[0069] It is understandable that when the battery cover 131 is closed on the opening of the battery cavity 111, the locking mechanism 134 can fix the battery cover 131 on the housing 11. The locking mechanism 134 improves the reliability of the battery cover 131 and helps to improve the sealing performance of the battery cover 131.

[0070] For example, the locking mechanism 134 may be a screw, pin, snap fastener, or other component.

[0071] In some embodiments, the shell 11 is provided with a locking groove 112, the locking mechanism 134 includes a locking tongue 1341 and a first elastic member 1342, the locking tongue 1341 is in sliding connection with the battery cover 131, and the first elastic member 1342 is connected between the shell 11 and the locking tongue 1341, and is used to push the locking tongue 1341 to insert into the locking groove 112, so as to lock the battery cover 131 and the shell 11.

[0072] The locking groove 112 can be a groove structure of the inner side wall of the shell 11.

[0073] The locking tongue 1341 is in sliding connection with the battery cover 131, and it can be understood that when the battery cover 131 covers the opening of the battery cavity 111, the locking tongue 1341 can slide relative to the battery cover 131 to extend into the locking groove 112, so as to lock the battery cover 131 and the shell 11; when the battery cavity 111 needs to be opened, the locking tongue 1341 slides reversely to exit the locking groove 112, so as to unlock the battery cover 131 and the shell 11, and facilitate the opening of the battery cover 131.

[0075] In some embodiments, the first elastic member 1342 is a spring, one end of the spring is hooked to the locking tongue 1341, and the other end of the spring is hooked to the battery cover 131.

[0076] In some embodiments, the locking mechanism 134 further comprises a sliding button 1343 connected with the lock tongue 1341 through the first cover 1313, and the sliding button 1343 is pushed to drive the lock tongue 1341 to slide, so as to realize the locking and unlocking of the locking mechanism 134.

The guide groove 13141 is used to limit the lock tongue 1341, so that the lock tongue 1341 can stably slide relative to the battery cover 131 to accurately extend into or exit the locking groove 112.

[0078] In some embodiments, the end cover assembly 13 further comprises a second elastic member 136 sleeved on the rotating shaft 133, and the two ends of the second elastic member 136 are connected with the battery cover 131 and the fixing seat 132, respectively. After the lock tongue 1341 exits the locking groove 112, the second elastic member 136 can automatically drive the battery cover 131 to flip, so as to realize the opening of the battery cover 131. The second elastic member 136 can be a torsion spring or the like.

[0079] Please refer to Figures 7-9 In some embodiments, the fixing seat 132 is snap-connected with the shell 11.

[0080] The snap-connection refers to connecting two components together by elastic deformation or mechanical structure interlocking. The connection structure of the snap-connection has various forms, such as elastic buckle, dovetail groove, threaded snap-connection, rotary snap-connection, etc.
