In addition, when the tail cap 200 of the embodiment is applied to a flashlight, the tail cap 200 is connected to one end of the barrel 100, and the length direction of the barrel 100 is perpendicular to the first side 211 of the base 210, so that the limiting groove 221 extending along the direction perpendicular to the base 210 can limit the circuit board in the length direction of the barrel 100, the circuit board in the barrel 100 can extend along the length direction of the barrel 100, and the charging contact 213 and the charging interface 214 for charging on the tail cap 200 are also convenient to connect with the first circuit board 300 and the second circuit board 400 through the tail cap 200, and the tail cap 200 is sealed at one end of the barrel 100, thereby forming a layout along the length direction of the barrel 100, so that the space along the length direction of the barrel 100 is reasonably utilized, the barrel 100 can maintain a smaller radial dimension, and the user can carry or use the barrel 100 in a hand.
Referring to fig. 2 and 4, in some embodiments, the charging contact 213 and the through hole 216 for connecting the charging interface 214 are oppositely disposed on the base 210, so that the charging contact 213 and the charging interface 214 have a set distance therebetween, thus not affecting each other, and facilitating the arrangement of the first circuit board 300 and the second circuit board 400, avoiding structural interference. The first side 211 of the base 210 may be provided with a notch 215 recessed downward along a direction perpendicular to the first side 211, and the charging contact 213 is disposed in the notch 215, so that the charging contact 213 can be exposed from the notch 215 to the base 210 for contact charging with a contact charger, the exposed portion of the charging contact 213 may be located in the notch 215, and the exposed portion is not greater than the depth of the notch 215, thereby preventing the charging contact 213 from protruding from the first side 211 of the base 210 to affect the flatness, and preventing the charging contact 213 from being rubbed to affect the charging and discharging performance. The charging interface 214 is located beside the charging contact 213, and an opening of the charging interface 214 is exposed on the first side 211 of the base 210 for inserting a connector, and in some specific embodiments, the charging interface 214 may be a common interface, such as a Type-C interface, a USB interface, or a DC interface.
In the above-described embodiment, the charging contact 213 may be implemented in various ways, for example:
fig. 5 is an exploded view of a portion of the structure in fig. 4, fig. 6 is a schematic cross-sectional structure of a tail cap 200 according to an embodiment of the application, fig. 7 is a schematic structure of a conductive member 240 in the tail cap 200 according to an embodiment of the application, referring to fig. 4 to 6, a conductive member 240 may be disposed on a base 210, one end of the conductive member 240 is disposed in the base 210 and exposed to a first side 211 of the base 210 to form a charging contact 213, the other end of the conductive member 240 and a limiting portion 220 are disposed on a second side 212 of the base 210, and the other end of the conductive member 240 is electrically connected to a first circuit board 300, so that the charging contact 213 is contacted by a contact charger to charge a built-in power supply 500 connected to the first circuit board 300 in the flashlight. Referring to fig. 6 and 7, a bent connection end 241 may be disposed at one end of the conductive member 240 disposed in the base 210, and one side of the connection end 241 is exposed to the first side 211 of the base 210 to form the charging contact 213. The first bending portion 242 is disposed on the side of the connection end 241 facing away from the charging contact 213, so that the area and strength of the portion inside the base 210 can be increased, and the stability of connection between the conductive member 240 and the base 210 can be improved. Specifically, the conductive member 240 may be a sheet structure made of a conductive material, and one end of the conductive member 240 is bent to form the connection end 241. The base 210 can be manufactured by injection molding, and one end of the conductive element 240 and the base 210 are integrally formed, so that stable connection between the conductive element 240 and the base 210 is ensured, and an assembly process of the conductive element 240 can be omitted during flashlight assembly, so that assembly cost can be reduced to a certain extent.
Alternatively, the charging contact 213 and the conductive member 240 are provided as two separate structural members (not shown), for example, the charging contact 213 is disposed in the base 210 and exposed to the first side 211 of the base 210, so as to charge, the charging contact 213 is connected to the conductive member (not shown) on the second side 212 of the base 210, the conductive member 240 is used for electrically connecting with the first circuit board 300, and the charging contact 213 and the conductive member 240 may be made of conductive materials, respectively. In this embodiment, the charging contact 213 and the base 210 may be manufactured into an integral structure by an injection molding process, and one end of the conductive member 240 may be connected by welding, riveting, or the like. The other end of the conductive member 240 can be electrically connected to the first circuit board 300 positioned in the limiting groove 221, so that the built-in power supply 500 connected to the first circuit board 300 can be charged through the contact charger.
In some embodiments, referring to fig. 5 to 7, one end of the conductive member 240 for connecting to the first circuit board 300 may further be provided with a clamping portion 243, where the clamping portion 243 is used for clamping with the first circuit board 300, and it should be noted that a structure for matching with the clamping portion 243 to perform clamping may be correspondingly provided on the first circuit board 300, so as to facilitate clamping between the two. For example, the conductive member 240 extends from the second side 212 of the base 210 in a direction away from the base 210, a clamping portion 243 is disposed on a side of the conductive member 240 facing the first circuit board 300, the clamping portion 243 includes a plurality of claws, a grabbing groove 310 may be disposed on the first circuit board 300 located by the limiting groove 221 corresponding to the clamping portion 243, and a charging circuit connection structure may be disposed in the grabbing groove 310, so when the first circuit board 300 is assembled on the base 210 of the tail cap 200, the conductive member 240 can be clamped with the grabbing groove 310 of the first circuit board 300 by the claws and electrically connected with the charging circuit, and the claws and the grabbing groove 310 can effectively avoid relative movement between the connection end 241 and the first circuit board 300, thereby ensuring stability of electrical connection between the conductive member 240 and the first circuit board 300. In addition, the conductive member 240 may be made of a thin sheet structure made of a metal material, so as to form a metal spring with elasticity, and the second bending portion 244 bent toward the first circuit board 300 is disposed at a portion between the clamping portion 243 and the charging contact 213, so that the clamping portion 243 can abut against the first circuit board 300, and can be clamped with the first circuit board 300 by means of elasticity, so that the stability of the electrical connection between the conductive member 240 and the first circuit board 300 is further ensured.
For connection of the circuit board, in the related art, the circuit board is easy to loosen and generate displacement due to unreliable connection of the circuit board in the flashlight, so that the circuit connection is unreliable, and normal use of the flashlight is affected.
