In the description of the present disclosure, unless otherwise specified, the phrase "a plurality of" means two or more.
  • FIGS. 1 to 15 A specific structure of a cordless lamp of an embodiment of the present disclosure is described below with reference to FIGS. 1 to 15 .
  • an additional protective cover 82 effectively prevents inadvertent activation of the switch 7 caused by the button 81 being inadvertently pressed during product handling and transportation process. Therefore, the situation is avoided that the built-in power loss caused by the lighting of the cordless lamp during the handling process will affect the quality of the product shipped.
  • the button 81 includes a flexible piece 811 and a rigid piece 812 embedded in an end of the flexible piece 811 opposite to the trigger surface of the switch 7. It can be understood that if the flexible piece 811 is in direct contact with the trigger surface, during long-term use, it is easy to cause material fatigue, aging and other phenomena at an end of the flexible piece 811 that is in contact with the trigger surface, thereby making the flexible piece 811 ineffective when pressed and unable to be used normally.
  • the rigid piece 812 added in the present embodiment can effectively prevent the flexible piece 811 from being in direct contact with the trigger surface of the switch 7, thereby effectively improving a service life of the button 81 and improving reliability when the button 81 is pressed. At the same time, operation hand feeling of the button 81 is effectively improved, which effectively avoids occurrence of conditions such as pressing failure of the button 81.
  • the button assembly 8 further includes a mounting plate 83 connected to an inner sidewall of the housing.
  • the flexible piece 811 includes a body 8111 and a protruding ring 8112 arranged around the body 8111. An end of the body 8111 passes through the housing to be fitted with the protective cover 82, and another end passes through the mounting plate 83 to be fitted with the rigid piece 812.
  • the protruding ring 8112 is clamped between the mounting plate 83 and the inner sidewall of the housing. Therefore, the mounting plate 83 is capable of firmly pressing the button 81 in the housing, thereby better ensuring stability of the button 81.
  • one of the body 8111 and the sidewall of the housing is openly provided with an annular mounting groove, and the other one is provided with a mounting bump adapted to the mounting groove.
  • the housing is openly provided with the fitting hole, the sealing performance of the whole cordless lamp is reduced to a certain extent.
  • sealing at the fitting hole is better realized by mating of the mounting bump and the mounting groove and the pressing effect of the mounting plate 83 on the protruding ring 8112, thereby ensuring the sealing performance of the cordless lamp.
  • the circuit board 32 include a main control module, a light source control module, a charge management module, a discharge management module and a light source control module.
  • the charge management module and the discharge management module are each electrically connected to the main control module.
  • the light source control module is electrically connected to the light-emitting element 33.

  • the housing is provided with a charge interface and a discharge interface.
  • a charge structure is electrically connected to the charge management module.
  • the discharge interface is electrically connected to the discharge management module.
  • the circuit board 32 of the cordless lamp of the present disclosure includes the charge management module, and the discharge management module, that is to say, the cordless lamp of the present disclosure has a charge function and a discharge function.
  • the cordless lamp of the present disclosure has a charge function and a discharge function.
  • the cordless lamp is capable of charging other external devices, thereby expanding a use range of the cordless lamp.
  • the charge management module and the discharge management module are integrated into a charge and discharge module, and the charge interface and the discharge interface are integrated into a charge and discharge interface 6. Therefore, a structure of the circuit board 32 is simplified, and hole/groove structures on the bottom housing 1 and the cover housing 2 are reduced, thereby indirectly improving the sealing performance of the cordless lamp of the embodiment of the present disclosure.
  • the circuit board 32 is further provided with a charge and discharge indicator lamp electrically connected to the charge and discharge module. Therefore, the charge and discharge indicator lamp is capable of indicating a charging or discharging state of the cordless lamp, thereby giving a very intuitive display to the user.
  • the charge and discharge interface 6 is a non-plug type magnetic interface. It can be understood that the non-plug type magnetic interface ensures that the charge and discharge interface has good sealing performance with the bottom housing 1 or the cover housing 2. At the same time, an interface area 61 has no groove structure, making it not affected by foreign objects.
  • the charge and discharge interface 6 includes the interface area 61 formed on the bottom wall of the housing.
  • the interface area 61 is provided with two charge and discharge contact points 62 protruding on the interface area 61.
  • the interface area 61 is covered with a covering.
  • the two charge and discharge contact points 62 are magnetic contact points. It can be understood that since the charge and discharge contact points 62 protrude out from the interface area 61, there is no groove structure at an electrical connection of the whole charge/discharge interface. Therefore, the electrical connection is not affected by foreign objects after completion, and an integral clamping groove type of charging and discharging can be used.
  • the interface area 61 is coat with stainless iron sheets.
  • the charge and discharge contact points 62 are magnetic contact points
  • the magnetic contact charger connector can be used to charge a device through a magnetic force adsorption of the stainless iron sheets. Additionally or alternatively, the charge and discharge contact points 62 are the magnetic contact points, which is very convenient.
  • a top portion of the charge and discharge contact point 62 is flush with the bottom wall of the housing, and the interface area 61 is located at an edge position of the housing. It can be understood that since an area of the interface area 61 is relatively small, the bottom wall of the housing is flush with a top portion of the charge and discharge contact point 62, so that a surface of the housing of the whole cordless lamp is relatively flat. At the same time, the interface area 61 is located at the edge position of the interface housing. When the device uses an integral clamping groove of charging mode, an elastic charging electrode of a charger will not contact the interface area 61 and scratch the housing.
  • the housing is a plastic member, and a side surface of the charge and discharge contact point is sealed by the interface area 61 by injection molding. Therefore, the side surface of the charge and discharge contact point 62 and the interface area 61 are sealed by injection molding, thereby improving the sealing performance of the whole cordless lamp.
  • the circuit board 32 is provided with a welding hole 322.
  • An end of the charge and discharge contact point 62 is fitted in the welding hole 322 and is fixed to the circuit board 32 by soldering. In this way, connection stability between the charge and discharge contact point 62 and the circuit board 32 can be better ensured, which improves reliability, impact resistance and explosion-proof performance of the cordless lamp, thereby ensuring stable charging and discharging of the cordless lamp.

  • the limit slot 612 and the two guide slots 611 are distributed in an isosceles triangle.
  • a length of the limit slot 612 is perpendicular to a length of the guide slot 611. It can be understood that when the magnetic contact charger connector is close to the interface area 61, the charging or discharging connector and the charge and discharge contact point 62 will generate a relatively large magnetic absorption force.
  • the guide slot 611 located at an outer side of the charge and discharge contact point 62 is mated with a guide boss on the charging or discharging connector, so that the charging or discharging connector and the charge and discharge contact point 62 are easily aligned and in good contact.
  • the limit slot 612 in the interface area 61 is capable of well limiting a position of a charging or discharging connector. After the charging is completed, in removing the charging or discharging connector, the limit slot 612 serves as a fulcrum. Therefore, the charging or discharging connector can be easily removed.
  • the limit slot 612 is an arc-shaped groove, whereby when the guide boss of the magnetic contact charging or discharging connector rotates in the arc-shaped groove, an arc-shaped structure of an inner surface of the groove makes the guide boss smoothly rotate and easily taken out.
  • the bottom wall of the housing is provided with two first sliding grooves 15 located on two sides of the interface area 61, and a top wall of the housing is provided with two second sliding grooves 26 located on two sides of the interface area 61.
  • first sliding groove 15 and the second sliding groove 26 are used to position and clamp the cordless lamp onto the charging or discharging connector, thereby ensuring the stability of the cordless lamp.
  • the light-emitting element 33 includes a primary light source 331 and a secondary light source 332 disposed around the primary light source 331.
  • the light source control module includes a primary light source control module electrically connected to the primary light source 331 and a secondary light source control module electrically connected to the secondary light source 332. Therefore, independent control of the primary light source 331 and the secondary light source 332 enables the cordless lamp of the present embodiment to provide different light intensities and light-emitting effects, thereby expanding the use range of the cordless lamp.
  • the four secondary light sources 322 are capable of providing different combination prompts during a charge/discharge process of the cordless lamp, which can be applied in emergency or other scenes, thereby greatly improving the user experience.
  • the housing is provided with buttons connected to the secondary light source control module.
  • the user can press different buttons according to actual needs so that the secondary light source 322 provides different combined illuminating prompts. Operation of such button switching is very convenient, so that the user is convenient to switch states of the secondary light source 322, thereby greatly improving the user experience.

  • An adhesive is filled between the second locking protrusion 22 and the clamping groove 11 to form a second waterproof structure.
  • the first locking protrusion 21 is clamped on and abutted against the snap ring 12 so that the open end of the bottom housing 1 abuts against the open end of the cover housing 2 to form the first waterproof structure, and the adhesive is filled between the second locking protrusion 22 and the clamping groove 11 to form the second waterproof structure.

Materials of the bottom housing 1 and the cover housing 2 and a type of the adhesive can be selected according to actual needs and are not to be limited to the above description.
  • the cordless lamp of the present embodiment when assembling the cordless lamp of the present embodiment, firstly, it is necessary to place an appropriate amount of adhesive in the clamping groove 11, and the amount of the adhesive ranges from 1/5 to 1/3 of a depth of the clamping groove 11. Secondly, it is necessary to ensure that the first locking protrusion 21 is aligned with the snap ring 12, the second locking protrusion 22 of the cover housing 2 is inserted into the clamping groove 11, and the first locking protrusion 21 is clamped on and abutted against the snap ring 12. Finally, the adhesive is cured to realize adhesion between the bottom housing 1 and the cover housing 2. In order to ensure adhesion strength between the bottom housing 1 and the cover housing 2, curing may be performed twice or more times. Further, the curing may be normal temperature curing or ultraviolet curing. A specific curing type may be selected according to a type of the adhesive, and is not limited to the aforementioned normal temperature curing and ultraviolet curing.
  • the first locking protrusion 21 is provided with a first inclined surface 211 inclined in a downward direction toward an inner wall close to the cover housing 2.
  • the snap ring 12 is provided with a second inclined surface 121 inclined in an upward direction toward an inner wall away from the bottom housing 1. It can be understood that during an actual mounting process, in a process of inserting the second locking protrusion 22 of the cover housing 2 into the clamping groove 11, the first locking protrusion 21 needs to be moved from a position where the first locking protrusion 21 is clamped on and abutted against an upper end surface of the snap ring 12 to a position where the first locking protrusion 21 is clamped on and abutted against a lower cross section of the snap ring 12.

  • the reflecting member 34 may be in the shape of a frustum of a cone with a hollow structure 341 adhesive to the lamp hood 25.
  • the hollow structure 341 forms a concave lens structure on a bottom surface of the reflecting member 34 and an inner surface of the lamp hood 25, so that a position where the light-emitting element forms a critical reflection point with a wide angle of 158° is near a small end of the reflecting member 34, which further reduces a height of the reflecting member 34, thereby further reducing loss of light emitted by the light source 2 due to reflection of the small end of the reflecting member 34.
  • the above description is only an exemplary illustration of the reflecting member 34 and is not a complete limitation of the reflecting member 34. That is, in other embodiments of the present disclosure, the reflecting member 34 can be selected according to actual needs, and a maximum wide angle of the light-emitting element 34 is not limited to 158°.
  • a frosted structure is located at a position of the reflecting member 34 corresponding to an outer surface of the lamp hood 25. Since a frosted surface can scatter light, a shadow formed by the reflecting member 34 on the light outbound surface 251 is reduced, thereby further enhancing the focusing brightness of the cordless lamp.
  • the reflecting member 34 is made of transparent material, and most of the light emitted from the light-emitting element 33 can pass through the reflecting member 34, so that the focusing brightness of the cordless lamp is improved.
  • the information storage bar code can be a two-dimensional code, a non-contact Radio Frequency Identification (RFID) tag or a Near Field Communication (NFC) tag, etc.
  • RFID Radio Frequency Identification
  • NFC Near Field Communication
  • the information storage bar code can record identity information of the cordless lamp, such as a manufacturer, product parameters (e.g., a model of the lamp source) or a serial number of the cordless lamp.
  • the NFC chip may contain a unique serial number. That is, each NFC tag corresponds to one unique random serial number (anticounterfeiting code).
  • One serial number has N bits.
  • data written in the NFC chip may be burned, and the user may only read the data.
  • Content of the tag may also be encrypted.
  • Ciphertext is written into the tag, and obtained ciphertext and serial number are sent to a decryption server to get decrypted, and then the decryption server feeds back a result.
