[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0019] Please refer to Figures 1 to 4 This utility model discloses a battery, which includes a battery cell 100 and a circuit board 200. The circuit board 200 can manage and protect the battery, and can also provide a variety of additional functions.

[0020] The battery cell 100 has a tab 110. The tab 110 is a component that electrically connects the battery cell 100 to the circuit board 200. The circuit board 200 includes a circuit board body 210 and connection terminals 220. The connection terminals 220 are disposed on the circuit board body 210, and the connection terminals 220 can be disposed on the circuit board body 210 using surface mount technology.

[0021] The electrode 110 has a first snap-fit ​​portion, and the connection terminal 220 has a second snap-fit ​​portion. The first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​together so that the battery cell 100 is connected to the circuit board body 210 and electrically connected.

[0022] The battery disclosed in this application provides a first snap-fit ​​portion on the tab 110 of the cell 100, and sets the circuit board 200 to include a circuit board body 210 and a connection terminal 220. The connection terminal 220 is set to have a second snap-fit ​​portion, so that the cell 100 and the circuit board body 210 are connected and electrically connected through the snap-fit ​​of the first snap-fit ​​portion and the second snap-fit ​​portion. This eliminates the need for laser welding or other methods to connect the cell 100 and the circuit board body 210, thereby solving the problem in related technologies where the connection between the cell and the circuit board can easily lead to battery damage.

[0023] Furthermore, when the battery cell 100 is connected to the circuit board body 210 by a snap-fit ​​connection instead of laser welding, and the tab 110 is made of aluminum, there is no need to connect it to the battery cell 100 via a secondary adapter. This simplifies the process. In addition, compared to laser welding, the snap-fit ​​connection reduces the resistance at the connection point and improves the power transmission efficiency.

[0024] It should be noted that before the battery cell 100 is connected to the circuit board body 210, the connection terminal 220 is already set on the circuit board body 210. The circuit board body 210 and the connection terminal 220 are connected to the battery cell 100 as a whole through the snap-fit ​​of the first snap-fit ​​part and the second snap-fit ​​part.

[0025] Specifically, there are relatively many ways to implement the first and second locking parts. For example, the first locking part can be a component with a barb or wedge structure, and the second locking part can be a component with a hole or groove of the corresponding shape. When one end of the barb or wedge structure of the first locking part is inserted into the corresponding hole or groove, the first locking part will undergo elastic deformation. When fully inserted, the first locking part returns to its original shape and locks in the corresponding hole or groove.

[0026] In another embodiment, one of the first snap-fit ​​portion and the second snap-fit ​​portion can be a snap-fit ​​hole 111, and the other can be a snap-fit ​​protrusion, which can snap into the snap-fit ​​hole 111.

[0027] The battery disclosed in this application has a relatively simple structure by setting one of the first snap-fit ​​portion and the second snap-fit ​​portion as a snap-fit ​​hole 111 and the other as a snap-fit ​​protrusion.

[0028] To improve the stability of the connection between the snap-fit ​​protrusion and the snap-fit ​​hole 111, the second snap-fit ​​part can be a snap-fit ​​protrusion, and the first snap-fit ​​part can be a snap-fit ​​hole 111. The snap-fit ​​hole 111 of the tab 110 can be formed by drilling a hole at the head of the tab 110 during the cutting process of the tab 110.

[0029] The connecting terminal 220 may include a terminal body 221. The two opposite ends of the terminal body 221 (e.g., the first end and the second end distributed opposite to each other) can be bent and joined to form a receiving space 221a. The snap-fit ​​protrusion can be located within the receiving space 221a. When the circuit board body 210 is connected to the battery cell 100, the portion of the tab 110 with the snap-fit ​​hole 111 is located within the receiving space 221a, so that the snap-fit ​​protrusion and the snap-fit ​​hole 111 snap together within the receiving space 221a. This allows the inner wall surrounding the receiving space 221a to limit the tab 110, thereby improving the stability of the connection between the snap-fit ​​protrusion and the snap-fit ​​hole 111.

[0030] Optionally, the two mating ends of the terminal body 221 can be opposite to the snap-fit ​​protrusion, thereby distancing the snap-fit ​​protrusion from the two mating ends of the terminal body 221. Since the strength of the terminal body 221 is relatively low at the two mating ends, by setting the snap-fit ​​protrusion at the position opposite to the two mating ends of the terminal body 221, it is beneficial to alleviate the deformation of the terminal body 221 when the snap-fit ​​protrusion is connected to the snap-fit ​​hole 111.

[0031] It should be noted that the inner wall of the accommodating space 221a has a first sidewall that is opposite to the two ends of the terminal body 221. The snap-fit ​​protrusion is located on the first sidewall. The two ends of the snap-fit ​​protrusion that are opposite to the terminal body 221 mean that the two ends of the snap-fit ​​protrusion that are opposite to the terminal body 221 are opposite in the direction perpendicular to the first sidewall.

[0032] To further improve the stability of the connection between the snap-fit ​​protrusion and the snap-fit ​​hole 111, optionally, when the snap-fit ​​protrusion is snapped into the snap-fit ​​hole 111, the two mating ends of the terminal body 221 contact the top of the snap-fit ​​protrusion, thereby preventing the electrode tab 110 from coming off the top of the snap-fit ​​protrusion, and thus further improving the stability of the connection between the snap-fit ​​protrusion and the snap-fit ​​hole 111.

[0033] Optionally, the receiving space 221a may have a first opening and a second opening opposite to each other. The first opening may be used to allow the tab 110 to extend into the receiving space 221a. The connecting terminal 220 may also include a limiting part 222, which may be connected to the terminal body 221 and may be located at the second opening. The limiting part 222 may block at least part of the second opening.

[0034] The battery disclosed in this application embodiment has a limiting part 222, which blocks at least part of the second opening. This allows the limiting part 222 to limit the tab 110 at the second opening after the tab 110 extends into the receiving space 221a from the first opening, thereby preventing the tab 110 from extending into the receiving space 221a without restriction.

[0035] To avoid the situation where the locking hole 111 cannot engage with the locking protrusion before the locking hole 111 reaches the locking protrusion after the tab 110 makes contact with the limiting part 222, the limiting part 222 can optionally be recessed inward to the side away from the receiving space 221a, so that the recessed area of ​​the limiting part 222 can provide the tab 110 with a margin of movement, thereby allowing the locking hole 111 to engage with the locking protrusion better.

[0036] Optionally, the battery cell 100 may have multiple tabs 110, which may include a first tab and a second tab, with opposite polarities. For example, the first tab may be a positive tab and the second tab may be a negative tab, and each tab 110 has a corresponding connection terminal 220 on the circuit board body 210.

[0037] Optionally, the battery may include multiple cells 100, and the battery may also include a mounting bracket 300. All multiple cells 100 may be disposed on the mounting bracket 300, and all multiple cells 100 may be connected to and electrically connected to the circuit board body 210.

[0038] The battery disclosed in this application embodiment has a mounting bracket 300, which allows multiple battery cells 100 to be mounted on the mounting bracket 300. The multiple battery cells 100 can be connected to and electrically connected to the circuit board body 210, thereby forming an integral structure of multiple battery cells 100.

[0039] This application also discloses an electronic device, which includes the battery disclosed in the above embodiments.

[0040] The electronic device disclosed in this application embodiment, by setting the battery disclosed in the above embodiment, enables the battery cell 100 and the circuit board body 210 to be connected and electrically connected through the snap-fit ​​of the first snap-fit ​​part and the second snap-fit ​​part. This eliminates the need for the battery cell 100 and the circuit board body 210 to be connected by means of laser welding machine or other methods, thereby solving the problem in the related technology that the battery is easily damaged when the battery cell is connected to the circuit board.

[0041] Specifically, the electronic devices disclosed in this application can be mobile phones, tablets, game consoles, computers, etc., and this application does not impose specific restrictions on the types of electronic devices.

[0042] The above embodiments of this utility model mainly describe the differences between the various embodiments.
