Description

Technical Field

[0001] This utility model relates to the field of battery cell technology, and in particular to a battery cell with multiple tabs. Background Technology

[0002] A battery cell with multiple tabs is a bipolar battery cell, which means that the battery has two positive tabs and one negative tab. This design can form two circuits on a single cell, spreading the current and voltage of high-power fast charging. Due to its dual-path charging design, bipolar battery cells have high charging efficiency and are suitable for high-power fast charging.

[0003] Common battery cell structures with multiple tabs are relatively simple and lack reinforcing components. In actual use, the tab solder joints are prone to loosening due to external impacts, leading to unstable connections. Furthermore, the part of the tab extending from the battery cell is relatively fragile and easily breaks due to impacts, thus rendering the battery cell unusable. Utility Model Content

[0004] The purpose of this invention is to provide a battery cell with multiple tabs to solve the technical problems of insufficient protection and lack of reinforcement structure, thereby improving connection stability and protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A battery cell with multiple tabs includes a battery cell body, and a reinforcing mechanism is installed at the top of the battery cell body;

[0007] The reinforcement mechanism includes a fixing base, which is installed on the top of the battery cell body. A back plate is fixedly connected to the top of the fixing base near the back side. A sliding groove is provided on the top of the fixing base near the front side, and a clamping component is installed inside the sliding groove.

[0008] As a preferred embodiment of this utility model, the top of the battery cell body is near the back side, and a tab assembly is installed through the fixing base.

[0009] As a preferred embodiment of this utility model, a rubber gasket is adhered to the front side of the back plate.

[0010] As a preferred embodiment of this utility model, the clamping assembly includes a slide bar, which is slidably connected inside the slide groove. A slide base is fixedly connected to the top of the slide bar, and the front of the slide base extends through the back, with several fixing rods threadedly connected to the corresponding electrode lugs.

[0011] As a preferred embodiment of this utility model, the slide is made of L-shaped aluminum alloy and its surface is treated with nickel plating.

[0012] As a preferred embodiment of this utility model, a fixing block is welded to one end of the slide bar near the right side, and a threaded rod is threadedly connected to the inside of the fixing block extending to the fixing seat on the right side.

[0013] As a preferred embodiment of this utility model, a protective pad is adhered to one end of the threaded rod extending to the back of the slide block.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using the mounting base, back plate, slide rail and clamping components together, the front and back of the tab assembly can be protected to prevent the tab assembly from breaking due to impact, which greatly improves the protection effect of the tab assembly.

[0016] 2. By using the sliding bar, sliding block, fixing rod and threaded rod together, the fixing rod can be used with the back plate to clamp and fix the electrode lugs after welding is completed. Compared with the traditional single welding fixing method, the connection stability is greatly improved. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example:

[0023] like Figures 1 to 3As shown, a battery cell with multiple tabs includes a battery cell body 1. A reinforcing mechanism 2 is installed on the top of the battery cell body 1. The reinforcing mechanism 2 includes a fixing seat 201, which is installed on the top of the battery cell body 1. A back plate 202 is fixedly connected to the top of the fixing seat 201 near the back side. A sliding groove 203 is opened on the top of the fixing seat 201 near the front side. A clamping component 204 is installed inside the sliding groove 203.

[0024] like Figures 1 to 3 As shown,

[0025] Near the back of the main body 1, the top of the battery cell is fitted with a tab assembly 101 that passes through the mounting base 201. A rubber gasket 2021 is adhered to the front of the back plate 202 to prevent the tab assembly 101 from directly contacting the back plate 202, thus improving stability. The clamping assembly 204 includes a slide bar 2041 that is slidably connected inside the slide groove 203. A slide base 2042 is fixedly connected to the top of the slide bar 2041. The front of the slide base 2042 extends through the back, and several fixing rods 2043 are threadedly connected to the tab assembly 101. By rotating the fixing rods 2043, the back plate 202 can be used to clamp and reinforce the tab assembly 101, improving connection stability. The slide base 2042 is made of L-shaped aluminum alloy. Furthermore, the surface is treated with nickel plating, which improves the corrosion resistance of the slide block 2042 and thus extends its service life. A fixing block 2044 is welded to the right end of the slide bar 2041. A threaded rod 2045 is threadedly connected to the right side of the fixing block 2044 and extends into the interior of the fixing seat 201. By rotating the threaded rod 2045, it can be inserted into the interior of the fixing seat 201, which can fix the position of the slide bar 2041 and the slide block 2042, prevent them from sliding, and improve the stability of use. A protective pad is glued to the end of the threaded rod 2045 that extends to the back of the slide block 2042. The protective pad can prevent the threaded rod 2045 from directly contacting the tab assembly 101, thus improving the protection of the tab assembly 101.

[0026] In summary, when reinforcing a battery cell with multiple tabs by welding the tab assembly 101, firstly, rotate the threaded rod 2045 to disengage it from the fixed base 201. Then, pull the slider 2041 to the right to disengage the slider 2042 from the fixed base 201. After welding, insert the left side of the slider 2041 into the groove 203 from the right side of the fixed base 201, and flip the threaded rod 2045 back into the fixed base 201 to secure the reinforcing mechanism 2. Finally, rotate the fixed rod 2043 to clamp and reinforce the tab assembly 101 in conjunction with the back plate 202, completing the entire process. This significantly improves the protection of the tab assembly 101 and effectively enhances connection stability.
