[0070] Law enforcement officers wear body cameras and other electronic devices that integrate real-time audio and video recording, photography, and video recording functions during their work. Because body cameras are typically used outdoors for extended periods, their battery life is crucial. Existing body cameras are usually small in size, resulting in small batteries. These small batteries cannot provide long battery life, potentially causing the body camera to run out of power during use and affecting normal operation.

[0071] To solve the above problems, such as Figures 1 to 14 As shown, this utility model first provides a back clip structure to improve the battery life of electronic devices.

[0072] As Figure 1 , Figure 3 and Figure 7 illustrated, specifically, the back clamp structure is used for the host 5, including the back clamp body 1, the battery assembly 2 and the fixing piece 3, wherein: the battery assembly 2 includes the shell 21, the first battery 22 and the first connector 23, the shell 21 is connected with the back clamp body 1, the shell 21 is provided with the first containing cavity 211 and the first interface 212 communicated with the first containing cavity 211, the first battery 22 is arranged in the first containing cavity 211, the first connector 23 is electrically connected with the first battery 22, part of the first connector 23 exposes the first interface 212, and is used for being electrically connected with the host 5; the fixing piece 3 is arranged on the back clamp body 1 or the shell 21, and the fixing piece 3 is used for being connected with the host 5.

[0073] The back clamp structure provided by the utility model embodiment, after the fixing piece 3 is connected with the host 5, the user can wear the host 5 on clothes through the back clamp body 1, without holding the host 5, simple and convenient operation, and the host 5 can be prevented from falling; in the assembled state, the first connector 23 is electrically connected with the host 5 at the first interface 212, so that the first battery 22 can supply power to the host 5, and the size of the first battery 22 is not affected by the size of the host 5, thereby the endurance of the host 5 can be improved through the first battery 22, and the working time of the host 5 is prolonged.

[0074] The back clamp body 1 is the existing back clamp structure for electronic equipment, and the specific structure is not described in detail here.

[0075] As Figure 3 illustrated, the shell 21 includes the first shell 213 and the second shell 214 in sealing connection, and the first shell 213 and the second shell 214 surround to form the first containing cavity 211. Dividing the shell 21 into the first shell 213 and the second shell 214 can facilitate installing the first battery 22 into the first containing cavity 211 in the production and assembly process, and sealingly connecting the first shell 213 and the second shell 214 can prevent external water vapor or dust from entering the first containing cavity 211 through the gap between the first shell 213 and the second shell 214 to affect the normal work of the first battery 22. Specifically, the first shell 213 and the second shell 214 can be sealingly connected by ultrasonic welding, dispensing or the like to ensure the reliability and sealing property of the connection therebetween. The first shell 213 can be connected with the back clamp body 1, and the second shell 214 is arranged on the side of the first shell 213 away from the back clamp body 1; the second shell 214 can be connected with the back clamp body 1, and the first shell 213 is arranged on the side of the second shell 214 away from the back clamp body 1; or the first shell 213 and the second shell 214 can be jointly connected with the back clamp body 1. Furthermore, the first interface 212 can be arranged on the first shell 213 or the second shell 214, or can be surrounded by the first shell 213 and the second shell 214.

[0076] For the convenience of description, the following is described by way of example with the first shell 213 connected to the back clamping body 1 and the second shell 214 arranged on the side of the first shell 213 away from the back clamping body 1. Since the second shell 214 faces the host computer 5 in the assembled state, the fixing member 3 is preferably arranged on the second shell 214 to facilitate the connection of the shell 21 to the host computer 5.

[0077] As shown in Figure 2 and Figure 5 , the fixing member 3 is arranged on the shell 21, the shell 21 is capable of rotating about a preset axis relative to the back clamping body 1, and the back clamping structure further comprises a damping member 4 arranged between the shell 21 and the back clamping body 1. The shell 21 is connected to the host computer 5 through the fixing member 3, so that the host computer 5 can rotate about the preset axis together with the shell 21 relative to the back clamping body 1, thereby enabling the angle of the host computer 5 to be adjusted as needed for the user to use. The damping member 4 can increase the friction between the shell 21 and the back clamping body 1, thereby enabling the shell 21 and the host computer 5 to be limited, ensuring the stability of the shell 21 and the host computer 5 during use, and preventing the shell 21 and the host computer 5 from rotating relative to the back clamping body 1 accidentally to affect the normal use of the host computer 5.

[0078] As shown in Figures 4 to 5 , the back clamping structure further comprises a rotating shaft 6 extending along the preset axis, and the shell 21 rotates about the preset axis relative to the back clamping body 1 through the rotating shaft 6. Specifically, the rotating shaft 6 comprises a first limiting section 61, a second limiting section 62, and a rotating shaft section 63 connected to the first limiting section 61 and the second limiting section 62 at both ends. The first limiting section 61 is used to connect with the shell 21, and the second limiting section 62 is used to connect with the back clamping body 1. The first shell 213 is provided with a first shaft hole 219 with a diameter greater than or equal to the diameter of the rotating shaft section 63 and less than the diameter of the first limiting section 61, the rotating shaft section 63 passes through the first shaft hole 219, and the first limiting section 61 is limited to the side of the first shell 213 away from the back clamping body 1; the back clamping body 1 is provided with a second shaft hole 12 with a diameter greater than or equal to the diameter of the rotating shaft section 63 and less than the diameter of the second limiting section 62, the rotating shaft section 63 passes through the second shaft hole 12, and the second limiting section 62 is limited to the side of the back clamping body 1 away from the first shell 213. Thus, the shell 21 and the back clamping body 1 can be connected, and the shell 21 can rotate about the preset axis relative to the back clamping body 1, and the shell 21, the damping member 4, and the back clamping body 1 can also be limited in the axial direction of the preset axis.

[0079] As shown in Figure 4 , the back clamping structure further comprises a gasket 7 arranged between the first limiting section 61 and the first shell 213, and the rotating shaft section 63 passes through the gasket 7. The gasket 7 can increase the contact area between the first limiting section 61 and the first shell 213, thereby improving the connection strength between the shell 21 and the rotating shaft 6 and prolonging the service life of the shell 21, the back clamping body 1, and the rotating shaft 6.

[0080] As shown in Figure 6 , the first shell 213 is provided with a first dispensing groove 216 on the side of the first shell 213 facing the second shell 214 and located at the outer periphery of the first shaft hole 219. The shell 21 further comprises a second cover 217 covering the side of the first shell 213 facing the second shell 214. The second cover 217 is connected to the first shell 213 by dispensing sealing in the first dispensing groove 216. The second cover 217 can protect the first battery 22, prevent the shaft 6 from moving along the axial direction of the preset axis and colliding with the first battery 22, and also prevent external water vapor or dust from entering the first containing cavity 211 through the first shaft hole 219 to affect the normal work of the first battery 22. The second cover 217 can be made of polycarbonate or other materials.

[0081] As shown in Figures 4 to 5 , in one embodiment, the damping member 4 is connected to the first shell 213 of the shell 21. One of the damping member 4 and the back clip body 1 is provided with a plurality of grooves 11, and the other is provided with a plurality of protrusions 41 capable of cooperating with the grooves 11. When the shell 21 rotates relative to the back clip body 1 around the preset axis, the protrusion 41 can cooperate with any groove 11 to limit the shell 21 to the current position, so as to stabilize the host 5 at the current angle, further improve the stability of the host 5 during use, and ensure the normal use of the host 5. When adjusting the angle of the host 5, a larger force needs to be applied to the shell 21 and the host 5 first, so that the protrusion 41 is out of the groove 11, and then the shell 21 and the host 5 are controlled to rotate relative to the back clip body 1 around the preset axis. The number of protrusions 41 can be one or more, and the number of protrusions 41 is less than or equal to the number of grooves 11. When one of the protrusions 41 cooperates with any of the grooves 11, the remaining protrusions 41 also cooperate with the corresponding grooves 11. Of course, in other embodiments, the damping member 4 can be connected to the back clip body 1, and one of the damping member 4 and the first shell 213 is provided with a plurality of grooves 11, and the other is provided with a plurality of protrusions 41 capable of cooperating with the grooves 11.

[0082] As shown in Figure 5 , the first shell 213 is provided with a limiting groove 215 corresponding to the damping member 4 on the side of the first shell 213 facing the back clip body 1. At least part of the damping member 4 is embedded in the limiting groove 215 to prevent the damping member 4 from sliding along the radial direction of the preset axis relative to the first shell 213, and to ensure the stability and reliability of the connection between the damping member 4 and the first shell 213.

[0083] As shown in Figure 3 , Figure 7 , and Figure 14As shown, the battery assembly 2 further includes a first seal 24 plugged at the first interface 212. A first through hole 241 corresponding to the part of the first connector 23 exposed from the first interface 212 is provided on the first seal 24. The first seal 24 can prevent external water vapor or dust from entering the first accommodation cavity 211 through the first interface 212 and affecting the normal operation of the first battery 22. Specifically, the housing 21 is provided with a second glue application groove 218 on the outer periphery of the first interface 212. The first seal 24 and the housing 21 are hermetically connected by glue application in the second glue application groove 218. The first connector 23 includes a power board 231 and terminals 232 that are electrically connected to each other.
