[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The smart lock uses a rechargeable lithium battery, which includes four rechargeable lithium battery bodies 1 connected in series to form a battery pack. The bottom of the battery pack is equipped with a mounting component 2. The lithium battery body 1 has a built-in overcharge protection circuit, which is electrically connected to the charging interface of the lithium battery body 1. The output voltage of the battery pack is 14.8V.

[0019] Mounting assembly 2 includes a base 21, which is located at the bottom of the battery pack. Two series mounting brackets 22 are mounted on the top of the base 21 for connecting four lithium battery bodies 1 in series. Each series mounting bracket 22 has a mounting groove 23 for mounting the lithium battery bodies 1. The lithium battery bodies 1 are mounted on the inner wall of the mounting groove 23, and their positive and negative terminals are connected to contact pieces on the inner wall of the mounting groove 23 to achieve a series connection. The two series mounting brackets 22 are connected by a wire. A sleeve 24 is mounted on the surface of each series mounting bracket 22. A contact piece 200 is mounted on the top of the left series mounting bracket 22 and is connected to the battery pack. The sleeve 24 is made of insulating material and is open at both the top and bottom. The specific shape and structure formed by the lithium battery bodies 1 and mounting assembly 2 is suitable for smart locks.
