Specifically, when the heating member 301 is in an on state, if the temperature measured by the first temperature measuring apparatus 303 is lower than 40°C, the control unit 401 allows the heating member 301 to continue heating, and if the temperature measured by the first temperature measuring apparatus 303 is higher than or equal to 40 °C, the control unit 401 controls the heating member 301 to stop heating. When the heating member 301 is in an off state, if the temperature measured by the first temperature measuring apparatus 303 is lower than 40°C, the control unit 401 allows the heating member 301 to start heating.
[0131] Referring to FIG. 2 and FIG. 14, the child safety seat further includes: a thermal safety apparatus 50 arranged on the heating apparatus 30 and configured to cause the heating apparatus 30 to stop heating when the heating apparatus 30 reaches a first preset temperature. A maximum value of the second preset temperature is less than the first preset temperature. Specifically, when the heating apparatus 30 operates, if the temperature of the heating apparatus 30 exceeds the first preset temperature, for example, exceeds 60°C, the thermal safety apparatus 50 may break, thereby cutting off an electrical circuit of the heating member 301, causing the heating member 301 to stop heating. The thermal safety apparatus 50 is configured to prevent overheating of the heating apparatus 30, which may prevent damages to the heating apparatus 30 or other components of the child safety seat due to overheating and may also prevent injuries to the child passenger sitting in the child safety seat due to overheating of the seat cushion 20. In the embodiment shown in FIG. 14, the thermal safety apparatus 50 is arranged between the control apparatus 40 and the heating member 301, but this is only exemplary. Those skilled in the art may arrange the thermal safety apparatus 50 at any appropriate position in the circuit as required, as long as a requirement for cutting off the electrical circuit of the heating member 301 through the thermal safety apparatus 50 is met. Preferably, the thermal safety apparatus 50 is a resettable thermal fuse, which is connected in series in the electrical circuit of the heating member 301. The resettable fuse is limited to a first preset temperature, a resettable temperature, and a resettable time. When the temperature of the heating apparatus 30 exceeds the first preset temperature, the resettable fuse will break, thereby cutting off the electrical circuit of the heating member 301 so that the heating member 301 stops heating. When the temperature of the heating apparatus 30 remains below the resettable temperature for a period of time longer than the resettable time, the resettable fuse will resume conduction of a current. Optionally, the thermal safety apparatus 50 may alternatively be a disposable fuse. When the temperature of the heating apparatus 30 exceeds the first preset temperature, the disposable fuse will blow, thereby cutting off the electrical circuit of the heating member 301. Replacing the disposable fuse can resume the conduction of the current.
[0132] The thermal safety apparatus 50 may realize circuit breaking independently, which is particularly advantageous for certain extreme situations. For example, in a case where the control apparatus 30 fails, the control apparatus 30 does not control the heating member 301 to stop heating when the heating apparatus 30 exceeds the second preset temperature, thereby causing the heating member 301 to continue heating, so that the temperature of the control apparatus 30 rises above the first preset temperature. In this case, the thermal safety apparatus 50 breaks, cutting off the electrical circuit of the heating member 301 and causing the heating member 301 to stop heating, thereby realizing a "safety" function.
[0133] Referring to FIG. 5 to FIG. 7 and FIG. 14, FIG. 5 is a schematic perspective view of a seat according to an embodiment of the present disclosure; FIG. 6 is a schematic perspective view of the seat shown in FIG. 5, in which an upper cover is removed; and FIG. 7 is a schematic perspective view of the seat shown in FIG. 6, in which a fan is removed. In an embodiment, the child safety seat further includes: a ventilation apparatus 60 arranged in the seat 10 and electrically connected to the control apparatus 40. The ventilation apparatus 60 is configured to form air flow inside the seat 10 to reduce the temperature of the seat 10. Referring to FIG. 5 and FIG. 6, an accommodation cavity 102 is defined in the seat 10, the upper cover 101 is arranged to cover the accommodation cavity 102, and the ventilation apparatus 60 is arranged in the accommodation cavity 102. The ventilation apparatus 60 includes: a first fixed base 601 fixedly arranged in the accommodation cavity 102, an air duct 6011 being formed between the first fixed base 601 and the upper cover 101; and a fan 602 fixedly arranged on the first fixed base 601 and electrically connected to the control apparatus 40. An outlet 6021 of the fan 602 is in fluid communication with the air duct 6011. Room-temperature air driven by the fan 602 flows through the air duct 6011 and the first vents 1011 of the upper cover 101 into a region where the seat cushion 20 is located, to reduce the temperature of the seat cushion. In this embodiment, the air duct 6011 formed between the first fixed base 601 and the upper cover 101 defines a ventilation region on a side of the upper cover 101 facing away from the seat cushion 20. The ventilation region corresponds to at least part of a lower portion of the seat cushion 20. The room-temperature air driven by the fan 602 flows intensively in the region and flows out from the first vent 1011 to the seat cushion 20, and the airflow gathers in the part of the seat cushion 20 corresponding to the ventilation region, so the cooling is more targeted and more effective.
[0134] Referring to FIG. 7, FIG. 9, and FIG. 10, FIG. 9 is a schematic side sectional view of the child safety seat according to an embodiment of the present disclosure; and FIG. 10 is a partial enlarged view of Part A in FIG. 9. In an embodiment, the first fixed base 601 is provided with an air inlet 6013 and an air outlet 6014. The air inlet 6013 is in fluid communication with a third vent 120 at a backrest of the seat 10, and the air outlet 6014 is in fluid communication with the air duct 6011. Optionally, the air inlet 6013 is arranged at a portion of the first fixed base 601 close to the inlet 6022 of the fan 602. The arrangement of the air inlet 6013 can increase an air intake volume of the fan 602, thereby increasing an amount of air for cooling, to improve a cooling effect. It is to be noted that the number and the arrangement of the heat air inlet 6013 shown in FIG. 7 are both exemplary. Those skilled in the art may select the number and the arrangement of the air inlet 6013 according to an actual requirement, for example, the number and the arrangement of the inlet 6022 of the fan 602. [0135] Referring to FIG. 7 and FIG. 8, in an embodiment, the air duct 6011 is recessed in a direction away from the seat cushion 20 to define a ventilation region on a side of the upper cover 101 facing away from the seat cushion 20. The ventilation region corresponds to at least part of a lower portion of the seat cushion 20. The room-temperature air driven by the fan 602 flows intensively in the region and flows out from the first vent 1011 to the seat cushion 20, and the airflow gathers in the part of the seat cushion 20 corresponding to the ventilation region, so the cooling is more targeted and more effective. Further, a height of the air duct 6011 in an air circulation direction is less than a height of the air outlet 6014, so a space required by the air duct 6011 is smaller. Therefore, the first fixed base 601 occupies a smaller space, and an overall structure of the seat 10 is more compact. Further, a cross-sectional area of the air duct 6011 in the air circulation direction is larger than a cross- sectional area of the air outlet 6014, so that a flow rate of the airflow entering the air duct 6011 is reduced and pressure on a surrounding environment is increased, thereby improving a gas exchange capability and improving the cooling effect.
[0136] The first fixed base 601 further includes: a first guide rib 6012 arranged at an end of the first fixed base 601 close to the air outlet 6014. The first guide rib 6012 defines a first guide space 60121 between the air outlet 6014 and the air duct 6011. The first guide space 60121 is configured such that a cross-sectional area of the first guide space 60121 gradually becomes larger along a direction from the air outlet 6014 to the air duct 6011. Therefore, a flow rate of the airflow passing through the first guide space 60121 is reduced, and the pressure on the surrounding environment is greatly increased, thereby improving the gas exchange capability and improving the cooling effect. In addition, the guide space 60121 defined by the first guide rib 6012 guides the airflow flowing out of the outlet 6021 so that the airflow flows to the air duct 6011 as much as possible, to cool the part of the seat cushion 20 corresponding to the ventilation region. Therefore, the arrangement of the first guide rib 6012 improves utilization of the airflow and further improves the cooling effect. Referring to FIG. 8, in an embodiment, the ventilation apparatus 60 further includes: a second temperature measuring apparatus 603 arranged on the upper cover 101 and communicably connected to the control apparatus 40. The second temperature measuring apparatus 603 is configured to measure a real-time temperature of the seat 10. Specifically, the second temperature measuring apparatus 603 is a temperature sensor. The temperature sensor is arranged in the upper cover 101 to measure a real-time temperature near the upper cover 101 and the seat cushion 20. It is to be noted that although FIG. 8 shows that the second temperature measuring apparatus 603 is arranged in the middle of the upper cover 101 and has an elongated structure, this is only exemplary. Those skilled in the art may select the arrangement position and the shape of the second temperature measuring apparatus 603 according to an actual requirement. For example, the second temperature measuring apparatus 603 may be arranged on a side portion of the upper cover. Optionally, the second temperature measuring apparatus 603 may be in another shape, such as a circle or a rectangle. Optionally, a plurality of second temperature measuring apparatuses 603 may be arranged on the upper cover 101, and the control apparatus 40 evaluates a current real-time temperature near the seat cushion 20 through temperatures measured by the plurality of second temperature measuring apparatuses 603.
[0137] In an embodiment, the fan 602 is electrically connected to the control unit 401. The second temperature measuring apparatus 603 is communicably connected to the control unit 401. The control unit 401 is configured such that the control unit 401 controls the fan 602 to stop ventilation when a temperature measured by the second temperature measuring apparatus 603 is lower than a third preset temperature; and/or the control unit 401 controls the fan 602 to start ventilation or allows the fan to continue ventilation when the temperature measured by the second temperature measuring apparatus 603 reaches the third preset temperature.
[0138] Referring to FIG. 1 Aand FIG. 8, the operating unit 402 is configured to adjust an operating state of the ventilation apparatus 60. In the embodiment shown in FIG. 8, the position of the operating unit 402 may be similar to that in the embodiment shown in FIG. 1 A. The operating unit 402 includes at least one switch. The at least one switch is configured to control ON and OFF of the fan 602. Optionally, the operating unit 402 includes a ventilation switch. The ventilation switch is configured to control ON and OFF of the fan 602.
[0139] Optionally, in the embodiment shown in FIG. 8, the control unit 401 further includes: a wireless communication module. The wireless communication module may be similar to the wireless communication module in the embodiment shown in FIG. 1 A. After the control unit 401 is wirelessly and communicably connected to an external device through the wireless communication module, through application software running on the external device, operating parameters of the ventilation apparatus 60 may be set and the operating state of the ventilation apparatus 60 may be controlled.
[0140] A Bluetooth communication module and a mobile phone are taken as examples below to describe an operating mode of the ventilation apparatus 60 provided in the embodiments of the present disclosure. After the control unit 401 is wirelessly and communicably connected to the mobile phone through the Bluetooth communication module, the user may set operating parameters of the ventilation apparatus 60 and control the operating state of the ventilation apparatus 60 through an application program running on the mobile phone. For example, the user may control ON and OFF of the ventilation apparatus 60 through the application program running on the mobile phone. For example, the user may set the third preset temperature to, for example, 30°C through the application program running on the mobile phone. Specifically, when the fan 602 is in an on state, if the temperature measured by the second temperature measuring apparatus 603 is lower than 30°C, the control unit 401 controls the fan 602 to be turned off, and if the temperature measured by the second temperature measuring apparatus 603 is higher than or equal to 30°C, the control unit 401 allows the fan 602 to continue operating. When the fan 602 is in an off state, if the temperature measured by the first temperature measuring apparatus 303 is higher than or equal to 30 °C , the control unit 401 controls the fan 602 to start.
[0141] Referring to FIG. 9 and FIG. 10, in an embodiment, a second fixed base 103 is further arranged in the accommodation cavity 102. The second fixed base 103 is fixedly connected to a side of the first fixed base 601 facing away from the upper cover 101. A safety belt guide groove 1031 is defined between the second fixed base 103 and the first fixed base 601. Specifically, the safety belt guide groove 1031 is adapted to allow a safety belt to pass therethrough. On the one hand, the safety belt guide groove 1031 provides a passage path for the safety belt to facilitate layout of the safety belt in the child safety seat. On the other hand, the safety belt guide groove 1031 and the safety belt passing therethrough isolate the air duct 6011 above the safety belt guide groove 1031 from components below the safety belt guide groove 1031, to ensure the safe operation of the components below the safety belt guide groove 1031, which will be continuously described below.
[0142] Referring to FIG. 11 to FIG. 13, in an embodiment, the first fixed base 601 further includes: a second guide rib 6015 arranged at an end of the first fixed base 601 away from the air outlet 6014. The second guide rib 6015 defines a second guide space 60151 in the air duct 6011. The second guide space 60151 is configured such that a cross-sectional area of the second guide space 60151 gradually decreases along the direction from the air outlet 6014 to the air duct 6011. Therefore, a flow rate of the airflow passing through the second guide space 60151 is reduced, and the pressure on the surrounding environment is greatly increased, thereby improving the gas exchange capability and improving the cooling effect. Specifically, the second guide rib 6015 has a U-shaped structure, and the second guide rib 6015 is arranged at a position opposite to the air outlet 6014. The U-shaped portion of the second guide rib 6015 is in communication with the safety belt guide groove 1031. After passing through the safety belt guide groove 1031, the safety belt (crotch strap) passes through the U-shaped portion of the second guide rib 6015 and then further passes through a crotch strap opening portion of the upper cover 101, thereby preventing an excessively large bending angle of the crotch strap between the safety belt guide groove 1031 and the crotch strap opening portion. A lower cover 104 is further arranged in the accommodation cavity 102. The lower cover 104 is connected to a side of the second fixed base 103 facing away from the first fixed base 601. Amounting space 1041 is defined between the lower cover 104 and the second fixed base 103, and the control unit 401 is fixedly arranged in the mounting space 1041. In this embodiment, the side of the second fixed base 103 facing away from the first fixed base 601 extends in a direction away from the first fixed base 601 to form a hollow structure, and the lower cover 104 and the hollow structure together define the mounting space 1041. The control unit 401 is fixedly arranged on the lower cover 104 to be accommodated in the mounting space 1041. Optionally, the control unit 401 is a control circuit board. In this embodiment, the fan 602 and the air duct 6011 are arranged above the safety belt guide groove 1031, and the control unit 401 is arranged in the mounting space 1041 below the safety belt guide groove 1031. Therefore, the safety belt guide groove 1031 and the safety belt passing therethrough isolate the air duct 6011 above the safety belt guide groove 1031 from the control unit 401 arranged in the mounting space 1041 below the safety belt guide groove 1031, to prevent damages to the control unit 401 caused by contact of other components of the child safety seat or foreign matter in the air sucked by the fan 602 with the control unit 401.
[0143] Referring to FIG. 15, FIG. 17, and FIG. 19, in an embodiment, a child safety seat is further provided, including a seat 10 including an upper cover 101; a plurality of fans 602; and a plurality of air guide members 604. The plurality of air guide members 604 are in fluid communication with the plurality of fans 602 respectively. Air flow is formed inside the seat 10 through the fan 602 and the air guide member 604 to reduce the temperature of the seat 10 and provide comfortable experience for the user.
[0144] Referring to FIG. 20 and FIG. 21, in an embodiment, the air guide member 604 is provided with a hollow air duct 6011 and a plurality of second vents 6044. The second vents 6044 are arranged on at least one side facing the upper cover 101 and are in fluid communication with the air duct 6011. The fan 602 drives the air to pass through the air duct 6011 of the air guide member 604 and flow out from the second vent 6044. The flowing air can reduce a temperature of a region near the upper cover 101 of the seat 10. The air guide member 604 and the air duct 6011 are basically straight lines along a front-rear direction of the seat 10 to reduce noise caused by large-angle bending of the air duct.
[0145] Referring to FIG. 17 and FIG. 19, in an embodiment, the plurality of air guide members 604 are located on two sides of the upper cover 101 respectively, and the plurality of air guide members 604 and the upper cover 101 form a recess 6045. Those skilled in the art may understand that a combination of the plurality of independent air guide members and the plurality of fans can ensure airflow pressure at the air outlet and also effectively reduce the operation of the fan and the noise of the air duct. The arrangement of the plurality of air guide members 604 on two sides of the upper cover can maximize a contact area while ensuring strong air outlet pressure, so as to improve heat dissipation efficiency. In this embodiment, two air guide members 604 are provided, each air guide member 604 is connected to one fan, and air ducts of the two air guide members 604 are independent of each other to prevent loss of wind pressure due to mutual interference between the fans. The fan is connected to a front end of the air guide member 604, that is, the end away from the backrest of the seat. The carrying rib 6041 is located at a back end of the air guide member 604, that is, the end close to the backrest of the seat. A general region of the recess 6045 is exemplarily shown by dash-dotted lines in FIG. 17. Specifically, opposite edges of the air guide members 604 located on two sides of the upper cover 101 and the upper cover 101 jointly define the recess 6045. The recess 6045 is adapted to provide guidance and accommodation spaces for the safety belt of the child safety seat. Referring to FIG. 15 and FIG. 17 together, FIG. 15 exemplarily shows a structure of the safety belt of the child safety seat exposed from the seat 10, and FIG. 17 exemplarily shows a structure of the safety belt of the child safety seat located on a back side of the upper cover 101 (inside the seat 10) with dash-dotted lines. For example, the safety belt includes: a shoulder strap 81, a waist strap 82, a crotch strap 83, and a latch 85. The shoulder strap 81, the waist strap 82, and the crotch strap 83 may be locked by the latch 85 (e.g., a five-point buckle). The shoulder strap 81 penetrates from a safety belt hole in a back 11 of the seat 10 into the back side of the upper cover 101 (i.e., enters the interior of the seat 10), passes through the recess 6045, and passes through a through hole 1015 provided in the upper cover 101, so that a tail end of the shoulder strap 81 is exposed from the upper cover 101. A length adjustment strap 84 is formed at the tail end of the shoulder strap 81 exposed from the upper cover 101. The user adjusts a length of the shoulder strap 81 by pulling the length adjustment strap 84. In this embodiment, the recess 6045 provides at least limiting and guiding functions for the shoulder strap 81. The through hole 1015 is in communication with the recess 6045. Preferably, the through hole 1015 is arranged at a front end of the seat portion 12 of the seat 10, and the fans 602 are spaced apart from each other, leaving a gap for guidance. A width of the gap is less than a width of the recess 6045. The length adjustment strap 84 passes through the gap in the fan 602 before passing through the through hole 1015.
[0146] Referring to FIG. 19 and FIG. 20, in an embodiment, the child safety seat further includes a fixed plate 605, the fixed plate 605 is fixedly connected to at least two air guide members 604 of the plurality of air guide members 604, and the fixed plate 605 forms a channel 6051 with the recess 6045. Specifically, the fixed plate 605 covers a side of the recess 6045 away from the upper cover 101 to form a channel 6051 together with the recess 6045, and a region of the channel 6051 is approximately the same as a region of the recess 6045 (e.g., a region between the dash-dotted lines in FIG. 17). In this embodiment, the channel 6051 extends from the top of the backrest of the seat 10 to the through hole 1015 located at the front end of the seat 10, and the through hole 1015 is in communication with the channel 6051. Through the formation of the channel 6051, accidental contact of the shoulder strap 81 limited and guided in the recess 6045 with other components inside the seat 10 can be prevented, ensuring smooth guidance of the shoulder strap 81. It is to be noted that guiding the shoulder strap 81 through the recess 6045 or the channel 6051 is only exemplary, and other components of the safety belt, such as the crotch strap, the waist strap, and energized wires, may also be guided through the recess 6045 or the channel 6051, which is not limited in the present disclosure. [0147] Referring to FIG. 20, in an embodiment, a guide portion 6046 is arranged at an end of the fixed plate 605 in a vertical direction, and the guide portion 6046 is adapted to fit the upper cover 101 to form a guide opening for the safety belt. Preferably, guide portions 6046 are arranged at two ends of the fixed plate 605 in the vertical direction. Optionally, the guide portion 6046 is a plate-shaped structure protruding from an edge of the fixed plate 605 in the vertical direction in a direction away from the fixed plate 605.
[0148] Referring to FIG. 19 to FIG. 21, in an embodiment, the fixed plate 605 is arranged to extend from the back 11 of the seat 10 to the seat portion 12 of the seat 10, and the fixed plate 605 includes: a back section 6055, a seat section 6056, and a connecting section 6057. The back section 6055 is arranged, for example, on the back 11 of the seat 10. The seat section 6056 is arranged, for example, on the seat portion 12 of the seat 10. The connecting section 6057 is connected between the back section 6055 and the seat section 6056. Optionally, a shape of the connecting section 6057 matches a shape of the corresponding portion of the upper cover 101. Preferably, the connecting section 6057 is configured in an arc shape. Optionally, the air guide member 604 is provided as an elongated structure and extends from the back of the seat 10 to the seat portion of the seat 10. The elongated air guide member 604, on the one hand, can ensure wind pressure of the flowing air in the air duct 6011, and on the other hand, can cover a region from the back 11 of the seat 10 to the seat portion 12 as much as possible, so as to increase an area of a heat dissipation region and optimize a heat dissipation effect. Further, curvature of the air guide member 604 is less than 90 degrees to reduce loss of the passing airflow and increase the air outlet pressure at the vents (for example, the second vent 6044 and a ventilation opening 1019).
[0149] Referring to FIG. 17 and FIG. 18, in an embodiment, the air guide member 604 is provided with a carrying rib 6041, the upper cover 101 is provided with a first rib 1016 extending along a vertical direction, a carrying hole 1012 is arranged in a side wall of the first rib 1016, and the carrying rib 6041 is inserted into the carrying hole 1012 to be fixed to the upper cover 101, improving space utilization in a height direction. In addition, since resonance may occur between the plurality of independent air guide members, which may cause fixed screws to loosen, the insertion and fixation manner can improve an anti -resonance capability of the air guide member and improve stability of a fixed connection. Optionally, an end of the carrying rib 6041 that passes through the carrying hole 1012 is provided with an air opening 1013, and the air opening 1013 is in fluid communication with the air duct 6011. Through the arrangement of the air opening 1013, the flowing air in the air duct 6011 flows out from the air opening 1013 to reduce a temperature of a region of the upper cover 101 near the air opening 1013, thereby improving the heat dissipation effect. Optionally, the upper cover 101 is further provided with a second rib 1017 extending along a horizontal direction, and the first rib 1016 and the second rib 1017 form a reinforcing groove 1018 in the upper cover 101. In the reinforcing groove 1018, the first rib 1016 and the second rib 1017 intersect each other to form a cavity structure. The reinforcing groove 1018 is further provided with the ventilation opening 1019, and the air opening 1013 is in fluid communication with the upper cover 101 through the ventilation opening 1019. In this embodiment, on the one hand, structural strength near the carrying hole 1012 is strengthened through the formation of the reinforcing groove 1018, so as to ensure support for the carrying rib 6041, and on the other hand, the cavity structure in the reinforcing groove 1018 increases an air outlet area, resulting in more vacant space near the air opening 1013 and less resistance to air flow. In some embodiments, at least part of the vents (e.g., the second vents 6044 and the ventilation opening 1019) are arranged adjacent to two wings of the seat 10 to ensure that the vents are not completely covered by the baby's buttocks, thereby increasing efficiency of air outlet.
[0150] Referring to FIG. 17 and FIG. 18, in an embodiment, the upper cover 101 is provided with a plurality of first vents 1011 located above the air guide members 604 and pores 1014 located above the recess between the air guide members 604. Optionally, the first vent 1011 and the second vent 6044 of the air guide member 604 are arranged to overlap, so that the flowing air in the air duct 6011 can flow out to an upper surface of the upper cover 101, and hot air on the upper surface of the upper cover 101 can flow into the pores 1014 above the recess, to enhance the heat dissipation effect. In some embodiments, referring to FIG. 20, the air guide member 604 on the left side discharges air towards the upper surface of the upper cover 101 through the first vent 1011, and the air guide member 604 on the right side draws air from the upper surface of the upper cover 101 through the first vent 1011. In some other embodiments (not shown), more than two air guide members are arranged on the left and right sides of the seat respectively. In the air guide members on the left side, one part of the air guide members discharge air towards the upper surface of the upper cover through the first vents, and the other part of the air guide members draw air from the upper surface of the upper cover through the first vents, to form an air flow circulation system on the left side. In the air guide members on the right side, one part of the air guide members discharge air towards the upper surface of the upper cover through the first vents, and the other part of the air guide members draw air from the upper surface of the upper cover through the first vents, to form an air flow circulation system on the right side.
[0151] Referring to FIG. 20 to FIG. 22, in an embodiment, the air guide member 604 includes: an air duct upper cover 6042 and an air duct lower cover 6043, and the air duct lower cover 6043 and the air duct upper cover 6042 are inserted into and engaged with each other to form the air duct 6011. The air duct upper cover 6042 is arranged on a side of the air guide member 604 close to the upper cover 101, and the second vent 6044 is arranged on the air duct upper cover 6042.

Therefore, gas exchange is allowed between the air duct 6011 of the air guide member 604 and the cavity 134 of the support cushion assembly 13. In actual use, through the gas exchange between the air duct 6011 and the cavity 134, heat in the support cushion assembly 13 is taken away to achieve an effect of lowering a temperature of the support cushion assembly 13. Specifically, in this embodiment, two ventilation holes 130 are provided, the two ventilation holes 130 are arranged on left and right sides of the upper cover 101 respectively, and one air guide member 604 is arranged below each ventilation hole 130, to provide a relatively uniform heat dissipation effect on the left and right sides of the upper cover 101. Those skilled in the art may understand that the numbers and the arrangement positions of the ventilation hole 130 and the air guide member 604 in this example are only exemplary, and those skilled in the art may select other suitable numbers and arrangement positions of the ventilation hole 130 and the air guide member 604 according to an actual requirement.
[0160] Still referring to FIG. 28 A to FIG. 30, in an embodiment according to the present disclosure, a lower portion of the support cushion assembly 13 is protrudingly provided with a connecting member 133, the air hole 1331 is formed in the connecting member 133, and when the support cushion assembly 13 is mounted on the seat 10, the connecting member 133 is at least partially inserted into the air outlet port 6047 to enter the air duct 6011 , so that the fan is in fluid communication with the cavity 134 inside the support cushion assembly 13. The support cushion assembly 13 includes a cushion body 131 and a cushion core 132. The cushion body 131 is provided with a through groove 1311 along a vertical direction. The cushion core 132 is inserted into the through groove 1311. Athickness of the cushion core 132 is less than a thickness of the cushion body 131. When the cushion core 132 is inserted into the through groove 1311, an upper surface of the cushion core 132 is slightly lower than an upper surface of the cushion body 131, thereby forming a cavity structure on a side of the support cushion assembly 13 close to the upper cover 101 to enhance heat exchange efficiency of the support cushion assembly 13. As shown in FIG. 28B, the support cushion assembly 13 further includes an outer shell, and the outer shell wraps the cushion body 131 and the cushion core 132. Therefore, the outer shell and a portion of the through groove 1311 not occupied by the cushion core 132 form the cavity 134. It is to be noted that in order to express internal features of the support cushion assembly 13, the outer shell is omitted in FIG. 28A and FIG. 36A. When the support cushion assembly 13 is mounted on the upper cover 101, part of the connecting member 133 is inserted into the air outlet port 6047 to enter the air duct 6011, in this case, the air duct 6011 is in fluid communication with the cavity 134 through the air holes 1331 in the connecting member 133, thereby realizing gas exchange between the air duct 6011 and the cavity 134. Specifically, in this embodiment, two connecting members 133 are provided, and the two connecting members 133 are both arranged on a bottom side of the support cushion assembly 13 and extend perpendicularly to a bottom surface of the support cushion assembly 13 in a direction away from the support cushion assembly 13. Those skilled in the art may understand that the number and the arrangement position of the connecting member 133 in this example correspond to the numbers and the arrangement positions of the ventilation hole 130 and the air guide member 604. In other embodiments, those skilled in the art may select other suitable numbers and arrangement positions of the connecting member 133 according to the numbers and the arrangement positions of the ventilation hole 130 and the air guide member 604. Further, the connecting member 133 may alternatively be used as a guide member when the support cushion assembly 13 is mounted, so as to rapidly position a mounting position of the support cushion assembly 13 on the upper cover 101.
[0161] Referring to FIG. 28 A and FIG. 28B, in an embodiment according to the present disclosure, a side of the cushion body 131 facing away from the upper cover 101 is an arc-shaped surface, and the arc-shaped surface is provided with a through groove 1311. The outer shell may be wrapped around an outer side of the cushion body 131. When the user sits on the seat 10, the body is in contact with the outer shell, resulting in higher comfort. The cushion core 132 is made of a breathable material to improve breathability, so as to further improve sitting comfort. In this embodiment, the through groove 1311 is approximately positioned at the user's buttocks or back, and the cushion core 132 is arranged in the through groove 1311 to provide support and reduce fatigue after long-term sitting. Optionally, a portion of the outer shell corresponding to the through groove may be made of a material or structure with better air permeability, such as mesh cloth, to further improve breathability of the region and provide better sitting experience. In this embodiment, the cushion body 131 and the cushion core 132 are arranged separately, and the user may replace the cushion core 132 with a different property (such as material or hardness) according to an actual requirement. In other embodiments, the cushion body 131 and the cushion core 132 may alternatively be integrally formed, to improve mounting convenience. Optionally, as shown in FIG. 26B, a seat cushion 135 may further be mounted on the upper surface of the support cushion assembly 13, for example, to improve sitting comfort or to be suitable for younger infants. As shown in FIG. 28B, in an embodiment according to the present disclosure, the seat cushion 135 may be detachably connected to the support cushion assembly 13, for example, via a connecting mechanism such as a button or Velcro. In other embodiments, the seat cushion 135 may be designed as a structure integrated with the support cushion assembly 13.
[0162] Referring to FIG. 32 to FIG. 34 together, in an embodiment according to the present disclosure, the air guide member 604 includes an air duct upper cover 6042 and an air duct lower cover 6043 inserted into and engaged with each other, and the air duct 6011 is formed between the air duct upper cover 6042 and the air duct lower cover 6043. Compared with the air guide member 604 in the foregoing embodiments, a side of the air guide member 604 in this embodiment facing the upper cover 101 is further provided with a protruding air outlet port 6047, and the air outlet port 6047 is inserted into the ventilation hole 130 of the upper cover 101.
[0163] Referring to FIG. 30 and FIG. 33 together, in an embodiment according to the present disclosure, a fan 604 is arranged at one end of the air guide member 604, and the fan 604 is in fluid communication with the air duct 6011 of the air guide member 604. Rotation of the fan 602 generates power for gas flow in the air duct 6011. A plurality of second vents 6044 are arranged in an upper portion of the air guide member 604, and the ventilation holes 130 are located between the fan 604 and the second vents 6044. The connecting member 133 includes a windward portion 1332, for example, facing the fan 604 and a windshielding portion 1333, for example, facing away from the fan 604. The windward portion 1332 is arranged in fluid communication with the air hole (1331). Specifically, the windward portion 1332 is provided with an aperture 13321, and the aperture 13321 is in fluid communication with the air hole 1331. The windshielding portion 1333 is arranged to isolate fluid communication between the fan 604 and the ventilation hole 130. Specifically, the windshielding portion 1333 is configured to block the flow of air in the portion of the air duct 6011 away from the fan 604 and the windshielding portion 1333. Therefore, when the support cushion assembly 13 is mounted on the seat 10, the connecting member 133 blocks the air duct between the fan 604 and the second vent 6044. Only a very small part (or even almost none) of the airflow generated by the fan 604 flows out of the air duct 6011 through the second vent 6044, but most (or even substantially all) thereof enters the cavity of the support cushion assembly 13 through the aperture 13321 of the windward portion 1332, and finally completes gas exchange with the outside of the child safety seat through micropores on the material of the outer shell. In this way, the airflow generated by the fan 604 is maximized to take away heat in the support cushion assembly 13 to optimize the effect of lowering the temperature of the support cushion assembly 13. Optionally, an end of the portion of the connecting member 133 inserted into the ventilation hole 130 away from the support cushion assembly 13 is in contact with an inner wall on a side of the air guide member 604 opposite to the ventilation hole 130 to enhance a blocking effect of the windshielding portion 1333 on the airflow, which further optimizes the effect of lowering the temperature of the support cushion assembly 13 and improves sitting comfort of smaller children.
[0164] Referring to FIG. 31Aand FIG. 3 IB, in an embodiment according to the present disclosure, the seat 10 further includes a shielding sheet 140 arranged on, for example, the upper surface of the upper cover 101 or seat cloth, and is configured to cover a partial region of the upper surface of the upper cover 101. For example, the shielding sheet 140 may cover the ventilation hole 130. Optionally, the shielding sheet 140 is provided with a hole-blocking member 141. When the shielding sheet 140 covers the ventilation hole 130, the hole-blocking member 141 closes the ventilation hole 130. Optionally, the hole-blocking member 141 has a plug-like structure to be embedded in and close the ventilation hole 130. When the support cushion assembly 13 is not mounted, the fan 604 is in communication with the second vent 6044 through the air duct 6011, and the ventilation hole 130 is closed through the shielding sheet 140 and the hole-blocking member 141, which can prevent the airflow from entering and exiting the ventilation hole 130, increase an air outlet volume at the second vent 6044, and improve sitting comfort of smaller children. In addition, an opening area of the ventilation hole 130 is larger than an opening area of the second vent 6044.
[0165] Optionally, in an embodiment according to the present disclosure, the shielding sheet 140 is a portion of the seat cloth covering the seat 10, and the shielding sheet 140 is pivotable relative to other portions of the seat cloth. Specifically, the shielding sheet 140 is, for example, substantially in a shape of a rectangle, and the shielding sheet 140 is pivotable with one of long edges thereof as an axis. In this way, the shielding sheet 140 is pivotable between an open position and an closed position. At the open position, the hole-blocking member 141 does not close the ventilation hole 130, so that the air hole 1331 can be in fluid communication with the air outlet port 6047. The shielding sheet 140 is part of the seat cloth. Therefore, the shielding sheet 140 is always on the upper cover 101, without fear of loss. Optionally, the shielding sheet 140 is made of a same material as other portions of the seat cloth, to reduce foreign body sensation to an occupant.
[0166] Referring to FIG. 35Aand FIG. 35B, in an embodiment according to the present disclosure, the connecting member 133 is a cover plate, and the cover plate is pivotably arranged in the air duct 6011. Specifically, the cover plate is pivotably connected to the air duct upper cover 6042, and the pivoting cover plate may change an opening degree of the air outlet port 6047, thereby adjusting a ventilation flow rate. Specifically, when the cover plate rotates to completely block the air outlet port 6047, the cover plate reaches a first position. For example, referring to FIG. 35B, the cover plate is at the first position and completely blocks the air outlet port 6047. In this case, the airflow cannot pass through the air outlet port 6047, so that the gas exchange between the support cushion assembly 13 and the air duct 6011 is isolated, and the airflow generally flows in the air duct 6011. In actual use, generally, if there is no need to mount the support cushion assembly 13 or provide ventilation and heat dissipation for the support cushion assembly 13, the cover plate is pivoted to the first position. Still referring to FIG. 35 A, the cover plate pivots to a second position and completely blocks the air duct 6011. In this case, the airflow is allowed to pass through the air outlet port 6047, so that the gas exchange between the support cushion assembly 13 and the air duct 6011 is allowed, and the airflow in the air duct 6011 is blocked by the cover plate. In actual use, generally, if there is a need to provide ventilation and heat dissipation for the support cushion assembly 13, the cover plate is pivoted to the second position.
[0167] In another embodiment according to the present disclosure, the cover plate may alternatively be arranged in the ventilation hole 130. For example, the cover plate is pivotably connected to a side wall of the ventilation hole 130, so that the cover plate is pivotable between the first position for blocking the ventilation hole 130 and the second position for blocking the air duct 6011. For example, when the cover plate pivots to the first position, the cover plate blocks the ventilation hole 130. In this case, the airflow cannot pass through the ventilation hole 130, so that the gas exchange between the support cushion assembly 13 and the air duct 6011 is isolated, and the airflow generally flows in the air duct 6011. In actual use, generally, if there is no need to mount the support cushion assembly 13 or provide ventilation and heat dissipation for the support cushion assembly 13, the cover plate is pivoted to the first position. When the cover plate pivots to the second position, the cover plate enters the air duct 6011 through the air outlet port 6047 and completely blocks the air duct 6011. In this case, the airflow is allowed to pass through the ventilation hole 130, so that the gas exchange between the support cushion assembly 13 and the air duct 6011 is allowed, and the airflow in the air duct 6011 is blocked by the cover plate. In actual use, generally, if there is a need to provide ventilation and heat dissipation for the support cushion assembly 13, the cover plate is pivoted to the second position.
[0168] Referring to FIG. 36Aand FIG. 36B, in an embodiment according to the present disclosure, a support cushion assembly 13 is further provided. Compared with the support cushion assembly 13 in the embodiments shown in FIG. 26 A to FIG. 35B, the support cushion assembly 13 in this embodiment is provided with two through grooves 1311 spaced apart from each other, the two through grooves 1311 are each provided with one cushion core 132 to form a cavity 34 respectively, and each cavity 134 is in fluid communication with at least one air hole 1331. In this embodiment, the two through grooves 1311 in the support cushion assembly 13 are spaced apart from each other and are not in communication with each other, thereby preventing the following situation: airflow generated by the fans 604 of the two air guide members 604 affect each other, such as generate vortexes, thereby weakening the flow of gas in the through groove 1311 and reducing the heat dissipation effect of the support cushion assembly 13.
[0169] The technical features in the above embodiments may be randomly combined. For concise description, not all possible combinations of the technical features in the above embodiments are described. However, all the combinations of the technical features are to be considered as falling within the scope described in this specification provided that they do not conflict with each other.
[0170] The above embodiments only describe several implementations of the present disclosure, and their description is specific and detailed, but cannot therefore be understood as a limitation on the patent scope of the present disclosure. It should be noted that those of ordinary skill in the art may further make variations and improvements without departing from the conception of the present disclosure, and these all fall within the protection scope of the present disclosure. Therefore, the patent protection scope of the present disclosure should be subject to the appended claims.
