As shown in FIG. 6 , the sliding of the upper case 1 on the lower case 5 includes a lid-opening motion along the lid-opening direction K and a lid-closing motion along the lid-closing direction G opposite to the lid-opening direction K. By moving the upper shell 1 away from the preset cover closing position and performing the cover opening movement, the top opening 56 is opened, the earphone slot 22 is exposed, and the earphones can be taken and placed. , as shown in Figure 8. The top opening 56 is gradually closed by the cover closing movement of the upper shell 1. When the movement reaches the preset cover closing position, the top opening 56 is completely covered by the upper shell 1, and the earphone slot 22 is covered by the upper shell 1, as shown in FIG. 6 . shown, the charging case is in the closed state.

The middle shell 2 is rotatably connected to the lower shell 5 . The rotation center line of the middle shell 2 is perpendicular to the cover opening direction K. In other embodiments, the rotation center line of the middle shell 2 may not be completely vertical with respect to the cover opening direction K, and there is a clamp close to 90° in the two directions. horn. Optionally, as shown in FIG. 5 and FIG. 6 , a shaft fixing part 58 is fixedly arranged in the lower casing 5 , a rotating shaft 54 is arranged on the shaft fixing part 58 , and the middle casing 2 is rotatably connected to the rotating shaft 54 , and the rotation center line of the middle casing 2 is is the centerline of the rotating shaft 54 .

The reset assembly is arranged on the lower shell 5 . As shown in FIG. 7 , after the upper shell 1 moves to the preset first reference position along the cover opening direction K, driven by the reset component, the upper shell 1 continues to open the cover and moves to the preset limit cover opening position, and the middle The casing 2 is rotated in the lifting direction until at least part of the structure thereon protrudes upwardly from the top opening 56 . That is to say, the preset first reference position and the preset limit opening position are two different positions of the upper shell 1 during the movement process. For example, in this embodiment, the preset first reference position is the preset cover closing position. A position between the preset limit opening position. In addition, the reset assembly can directly drive the upper shell 1 and/or the middle shell 2, or the reset assembly can drive the upper shell 1 and/or the middle shell 2 through a transmission structure.

In this embodiment, in the process of opening the cover, when the upper shell 1 is opened and moved to the preset first reference position, the reset component provides a driving force, so that the user does not need to apply external force to the upper shell 1, the upper shell 1 and the middle shell 2. The movement in the original direction can be automatically performed under the drive of the reset component, which improves the automation degree of opening the cover and the opening efficiency.

Further, as shown in FIGS. 6 to 8 , a linkage structure is provided between the upper shell 1 and the middle shell 2 . When the upper shell 1 moves between the preset second reference position and the preset limit opening position, the reset component drives the upper shell 1 to move along the cover opening direction K, and the linkage structure plays a linkage role, and the upper shell 1 is driven by the linkage structure. Shell 2 turns. At this time, the reset assembly can directly drive the upper shell 1, and the upper shell 1 and the linkage structure constitute a transmission structure, and the reset assembly can drive the middle shell 2 through the transmission structure.

Among them, it should be noted that in the process of opening the cover of the upper shell 1, the linkage structure can only play a linkage role when the upper shell 1 moves to the preset second reference position, and drive the middle shell 2 to rotate. , the upper shell 1 and the middle shell 2 move separately without interfering with each other; or, before the upper shell 1 moves to the preset second reference position, it will play a linkage role.

Wherein, the preset second reference position and the preset limit opening position are two different positions of the upper shell 1 during the movement process. In addition, the preset second reference position and the preset first reference position are the same position. In other embodiments, the preset second reference position may be different from the preset first reference position. For example, along the cover opening direction K, the preset first reference position is located in front of the preset second reference position.

In this embodiment, through the setting of the linkage structure, the simultaneity of movement of the upper casing 1 and the middle casing 2 can be improved, and the cover opening speed can be further ensured; at the same time, the setting of the reset assembly is simplified. When only one is directly driven by the reset component, the other can also be driven.

Further, as shown in FIGS. 6 to 8 , the linkage structure includes an upper casing push rod 16 fixed to the upper casing 1 and a middle casing slide rail 23 fixed to the middle casing 2 . When the upper shell 1 moves from the preset second reference position to the preset limit opening position, the upper shell push rod 16 presses the middle shell slide rail 23 to drive the middle shell 2 to rotate in the lifting direction.

In this embodiment, the linkage structure is set as the upper casing push rod 16 and the middle casing sliding rail 23, which is convenient for processing. In the process of opening the cover of the upper shell 1 , as shown in FIG. 7 , the upper shell push rod 16 pushes the middle shell slide rail 23 , thereby driving the middle shell 2 to rotate.

Further, as shown in FIG. 6 , the middle case slide rail 23 includes a front baffle wall 232 and a rear baffle wall 231 arranged in sequence along the cover opening direction K. As shown in FIG. When the upper case 1 is in the preset cover closing position to cover the top opening 56 , the bottom end of the upper case push rod 16 is higher than the top end of the front baffle wall 232 and lower than the top end of the rear baffle wall 231 .

As shown in FIG. 7 , when the upper case 1 moves to the preset second reference position along the cover opening direction K, the upper case push rod 16 abuts against the rear stop wall 231 , and continues to move in the original direction with the upper case 1 , as shown in FIG. 8, the upper casing push rod 16 gradually extends into the gap between the rear baffle wall 231 and the front baffle wall 232 until the front baffle wall 232 presses the upper casing push rod 16. The shell push rods 16 abut against each other, which can prevent the middle shell 2 from continuing to rotate and play a limiting role. In addition, in the process of closing the cover of the upper shell 1, the front blocking wall 232 pressed on it can be pushed in the reverse direction by the upper shell push rod 16, so as to drive the middle shell 2 to reset and move in the opposite direction of the lifting direction, so as to use the upper shell The cooperation of the push rod 16 and the sliding rail 23 of the middle shell realizes the bidirectional pushing of the middle shell 2 .

Of course, in other embodiments, the middle shell slide rail 23 may also only include the above rear baffle wall 231 . Correspondingly, through the setting of the positional relationship between the center of gravity of the middle shell 2 and the position of the rotation center line, the upper shell 1 can be closed during the closing movement of the upper shell 1. In the middle, the middle shell 2 can be reset and rotated by means of gravity.

Further, after the upper case 1 moves to the preset third reference position along the cover closing direction G, driven by the reset assembly, the upper case 1 continues to move to the preset cover closing position covering the top opening 56 in the original direction.

Wherein, in the opening direction K, the preset first reference position is located in front of the preset third reference position, or the two positions are the same. For example, in this embodiment, the preset first reference position and the preset third reference position are The same, that is to say, in the process of closing the cover, just after the upper case 1 passes through the preset first reference position, the cover can be automatically continued to be closed by the driving of the reset component.

Through the arrangement of this embodiment, the reset component can realize automatic cover closing in addition to automatic cover opening, which further facilitates the use of the charging box. In addition, the reset assembly provides a driving force in the opening direction K, and the driving force in the opposite direction is provided in the front of the preset first reference position and the rear of the preset third reference position in the cover opening direction K, so that the upper shell 1 has a movement in the opposite direction. trend to ensure the reliability of the drive.

Further, after the upper case 1 moves to the preset fourth reference position along the cover closing direction G, the middle case 2 rotates in the opposite direction of the lifting direction under the driving of the reset assembly and/or the driving of the upper case 1 . Wherein, in the cover opening direction K, the preset fourth reference position is located in front of the preset cover closing position. In this embodiment, the preset fourth reference position is the same as the preset limit opening position, so that when the upper shell 1 starts to close the lid, the middle shell 2 is automatically reset and rotated through the linkage structure.

With the arrangement in this embodiment, the reset and rotation of the middle shell 2 can also be automated, which further improves the convenience of use.

Further, as shown in FIGS. 4 and 5 , the reset assembly includes an upper shell elastic member 6 , the lower shell 5 is fixedly connected to the support block 52 and slidably connected to the upper shell slider 53 , and the upper shell elastic member 6 is connected to the upper shell slider 53 . and the support block 52 .

Cover slide 132 . Wherein, in the opening direction K, the preset first reference position is located in front of the preset fifth reference position, or the two positions are the same. For example, in this embodiment, the preset first reference position and the preset fifth reference position are same. That is to say, the upper shell elastic member 6 can not only provide a driving force during the lid opening process, but also provide a driving force for the upper shell 1 during the lid closing process.

More specifically, as shown in FIG. 4 , a control slideway is provided on the bottom surface of the upper shell 1 , and the control slideway sequentially includes a cover opening slideway 131 and a cover closing slideway 132 along the cover opening direction K, and the cover opening slideway 131 It is docked with the cover closing slideway 132, and the docking point is B.

When the upper shell slider 53 enters the cover opening slideway 131 through point B, the reset force of the upper shell elastic member 6 presses the upper shell slider 53, so that the upper shell slider 53 generates a pressure F1 against the cover opening slideway 131, and the pressure F1 has a component force F11 along the cover opening direction K, so that the upper cover 12 is automatically driven to open the cover by the elastic force of the upper case elastic member 6 until the end point C of the cover opening slideway 131 moves to the upper case slider 53 . touch.

Similarly, when the upper case slider 53 enters the cover closing slideway 132 through point B, the restoring force of the upper case elastic member 6 presses the upper case slider 53 so that the upper case slider 53 exerts pressure on the cover closing slideway 132 F2, the pressure F2 has a component force F21 along the cover closing direction G, so that the upper cover 12 is automatically closed by the elastic force of the upper case elastic member 6 until the end point A of the cover closing slideway 132 moves to the sliding position with the upper case. Blocks 53 are in contact.

Of course, in other embodiments, only one of the cover opening slideway 131 and the cover closing slideway 132 may be provided on the upper shell 1. For example, in the control slideway, only the cover opening slideway 131 is provided, and the cover is closed. The position of the slideway 132 is changed to a straight slideway parallel to the cover-opening direction K, so that the upper case slider 53 can not hinder the movement of the upper case 1, and also does not provide the cover in the cover-opening direction K or the cover-closing direction G. driving force.

Wherein, the control slideway is specifically a slideway structure provided on the upper shell 1 , and correspondingly, the upper housing slider 53 is slidably inserted into the control slideway. More specifically, as shown in FIG. 3 and FIG. 4 , the upper case 1 includes an upper cover 12 and an upper inner cover 13 fixed on the lower side of the upper cover 12 , specifically by means of dispensing.

In this embodiment, see FIG. 5 for details, the second magnetic member 82 and the fourth magnetic member 84 are respectively disposed on the side walls of the middle casing 2 on both sides of the rotating shaft 54 . Correspondingly, the first magnetic member 81 and the third magnetic parts 83 are respectively located on both sides of the rotating shaft 54 .

Specifically, in each magnetic attraction structure, both of the two magnetic attraction members may have magnetic magnets, and there is a magnetic force that attracts each other. Alternatively, one of the two magnetic attraction members is a magnet, and the other is a non-magnetic iron block.

In this embodiment, the magnetic attraction assembly is used to cooperate with the upper casing elastic member 6 to realize the automatic opening and closing of the cover and the automatic rotation process of the middle casing 2, which can further improve the convenience of use, and at the same time, the device has a simple structure and is easy to process.

In addition, it should be noted that the preset first reference position to the preset sixth reference position may correspond to the same position or different positions under the premise that the above constraints are met.

The working principle of the charging box provided in this embodiment is as follows:

After assembly, in the closed state as shown in Figures 4 and 6, the upper shell elastic member 6 is compressed to a certain extent in the control track, and the upper shell slider 53 is at point A, according to the inclination direction of the AB section of the control track. , the upper shell elastic member 6 has the force to stretch outward, so the upper shell 1 has the force and tendency to maintain the closing. The third magnetic element 83 and the fourth magnetic element 84 are in contact with each other to attract and keep the middle case 2 at the bottom of the lower case 5 .

When the upper case 1 is opened: push the upper case 1 along the cover opening direction K by hand, and the upper inner cover 13 slides on the sliding support portion 531 . At this time, the upper casing slider 53 moves from A to B, and forces the upper casing elastic member 6 to further elastically deform and accumulate force. As shown in FIG. 7 , when the upper casing slider 53 reaches point B, the upper casing elastic member 6 reaches the maximum value of stored force, and at this time, the upper casing push rod 16 contacts the rear stop wall 231 . Continue to push the upper shell 1 by hand, and the upper shell push rod 16 pushes the rear blocking wall 231, so that the middle shell 2 is rotated and lifted around the rotating shaft 54, and the third magnetic element 83 and the fourth magnetic element 84 are separated. As shown in Figures 4 and 8, the upper casing slider 53 moves from B to C. According to the inclination direction of the BC section of the control track, the upper casing elastic member 6 stretches outward, and the upper casing 1 is automatically opened, that is to say, In essence, after the upper shell slider 53 enters the BC section, release your hand, and the upper shell 1 and the middle shell 2 can continue to move automatically; the support block 52 contacts the mounting block 14 at one end of the limit slide The case 1 remains open. The middle shell 2 is in contact with the rotation stop 57 . At this time, the first magnetic element 81 and the second magnetic element 82 are attracted to each other, maintaining the raised state of the middle shell 2 , which is convenient for taking and placing the earphone 7 .

When closing the upper case 1 : push the upper case 1 along the cover closing direction G by hand, and the upper inner cover 13 slides on the sliding support portion 531 . At this time, the upper casing slider 53 moves from C to B, and forces the upper casing elastic member 6 to further elastically deform and store force. During this process, the upper casing push rod 16 pushes the front blocking wall 232 , so that the middle casing 2 rotates around the rotating shaft 54 and falls back down, and the first magnetic element 81 and the second magnetic element 82 are separated. When reaching point B, the upper shell elastic member 6 reaches the maximum value of stored force; the upper shell slider 53 moves from B to A, according to the inclination direction of the BA section of the control track, the upper shell elastic member 6 stretches outward, and the upper shell 1 is automatically closed; the support block 52 is in contact with the other end of the limit slide rail 15 to stop, and the upper shell 1 remains closed. At this time, the third magnetic attraction member 83 and the fourth magnetic attraction member 84 are attracted to each other close to each other, maintaining the sinking state of the middle shell 2 , which facilitates the storage of the TWS earphone 7 .

In the charging box provided in this embodiment, the upper shell 1 is a sliding cover type to open and close the cover; slide the upper shell 1 to open the cover to a certain distance, the upper shell 1 can be automatically opened, and keeps the trend of opening. In the process, the load The middle shell 2 of the earphone 7 is rotated, and the earphone 7 is pulled out of the box, which is convenient for taking and placing. In the same way, slide the upper shell 1 to close the cover to a certain distance, the upper shell 1 can be automatically closed, and the trend of closing is maintained. The capping and closing process is highly automated.

Obviously, in other embodiments, the preset first reference position may be set at other positions. In the second embodiment, the preset first reference position is the preset cover closing position, and at this position, the upper shell 1 and the lower shell 5 are snap-connected. After the buckle is released, the reset component starts to drive the upper shell 1 to open automatically. In addition, the linkage structure may not be provided between the upper shell 1 and the middle shell 2 . At this time, the reset assembly includes a first elastic member disposed between the upper shell 1 and the lower shell 5 and a second elastic member disposed between the middle shell 2 and the lower shell 5. When the first elastic member is snapped together, the first elastic member and the second elastic member are in a deformed state, the limit of the buckle prevents the first elastic member from driving the upper shell 1 to reset, and the middle shell 2 is pressed by the upper shell 1 to prevent the second elastic member from returning. , the reset movement of the first elastic piece drives the upper shell 1 to open, and at the same time, the reset movement of the second elastic piece drives the middle shell 2 to rotate.

In addition, as in the first embodiment, the reset assembly already includes a structure in which the upper shell elastic member 6 provides the driving force, and in the embodiment in which the linkage structure is provided, as in the third embodiment, a magnetic attraction assembly is further provided, but the The position where the magnetic force is provided is different from that of the first embodiment. In the process of opening the cover, after the upper shell 1 passes the preset reference position and moves a distance greater than 0, the magnetic attraction component provides the magnetic attraction force to the middle shell 2. Specifically, the magnetic attraction force can be provided when the middle shell 2 rotates to the end point. , the same is true when the cover is closed, so that the main function of the magnetic suction assembly is to lock the middle shell 2 at the limit position of its rotation, so as to improve the stability of the middle shell 2.

In addition, in the fourth embodiment, the magnetic attraction component provided by it includes only one of the cover-opening magnetic attraction component or the cover-closing magnetic attraction component of the first embodiment.

In addition, in none of the embodiments, the upper shell elastic member 6 in the first embodiment is cancelled, and the automatic rotation of the middle shell 2 is realized only by the driving force of the magnetic attraction assembly between the middle shell 2 and the lower shell 5 and by means of the linkage structure , while the automatic movement of the upper shell 1.
