Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lithium ion batteries, and in particular relates to a short-circuit-proof battery structure. Background Art
[0002] Lithium-ion batteries are small devices that generate electricity and are used in various electronic products, such as e-cigarettes. E-cigarettes are the preferred choice of most smokers due to their portability, ease of use, and lack of harmful fumes, particularly in recent years. To protect user health, disposable e-cigarettes have been introduced. Lithium-ion batteries are installed inside disposable e-cigarettes. These batteries are typically connected by welding the tabs on the battery to the terminals on the circuit board inside the e-cigarette. After using a disposable e-cigarette, users typically remove the battery for recycling to protect the environment. However, the tabs on the removed battery are exposed and easily come into contact with other objects, potentially causing a short circuit in the battery and posing a safety hazard. Utility Model Content
[0003] The purpose of the present utility model is to provide a battery structure that can solve the above problems.
[0004] To achieve the above-mentioned purpose, an embodiment of the present invention provides a short-circuit-proof battery structure, including a battery body and a rubber cover, wherein the rubber cover is installed at one end of the battery body, and the battery body is provided with two pole ears arranged at the same end as the rubber cover, and the end of the rubber cover away from the battery body is provided with a groove corresponding to the pole ear, the pole ear passes through the corresponding groove, and the through end of the pole ear is formed with a connecting portion by bending, and the connecting portion abuts against the bottom wall of the groove.
[0005] Optionally, a boss is provided on the bottom wall of the groove, and the connecting portion is in close contact with the boss.
[0006] Optionally, a limiting notch is provided at the lower end of the rubber cover.
[0007] Compared with the prior art, the beneficial effect of the present invention is that the grooves accommodate the connecting parts, thereby preventing the two connecting parts from being directly exposed to the outside, effectively avoiding the problem of the two connecting parts contacting external objects and causing battery short circuit, and greatly improving the safety of the battery structure.

[0018] like Figure 1 and 2 As shown, an embodiment of the present invention provides a short-circuit-proof battery structure, including a battery body 100 and a rubber cover 200 .
[0019] In which, the rubber cover 200 is installed at one end of the battery body 100, and the battery body 100 is provided with two pole ears 110 arranged at the same end as the rubber cover 200, and the end of the rubber cover 200 away from the battery body 100 is provided with a groove 210 corresponding to the pole ear 110, the pole ear 110 passes through the corresponding groove 210, and the through end of the pole ear 110 is formed with a connecting portion 111 by bending, and the connecting portion 111 is in contact with the bottom wall of the groove 210, that is, the connecting portion 111 is accommodated by the groove 210, thereby avoiding the two connecting portions 111 from being directly exposed to the outside, and avoiding the problem of the two connecting portions 111 contacting external objects and causing a battery short circuit, which can greatly improve the safety of the battery structure.
[0020] In one embodiment, a boss 211 is provided on the bottom wall of the groove 210 , and the connecting portion 111 is in close contact with the boss 211 , thereby ensuring stability when the connecting portion 111 is connected to a metal dome (not shown) on the electronic cigarette.
