Description

A battery cover Technical Field

[0001] This invention belongs to the field of battery appliance technology, and specifically relates to a battery cover. Background Technology

[0002] In existing technology, the battery cover body is provided with an injection hole for injecting electrolyte into the battery. The top surface of the injection hole is flush with the top surface of the cover body. In actual production, the electrolyte is prone to overflow from the injection hole to the outside during injection, resulting in electrolyte residue on the cover body. Since electrolyte is flammable and volatile, it can easily pollute the workshop environment and pose a safety hazard. Therefore, it is very necessary to provide a battery cover that is simple in structure, easy to use, avoids electrolyte overflow, and eliminates safety hazards. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery cover that is simple in structure, easy to use, prevents electrolyte leakage, and eliminates safety hazards.

[0004] The objective of this invention is achieved as follows: a battery cover plate includes a cover plate body, wherein an injection hole is provided on the cover plate body, and a surrounding barrier is provided around the injection hole; an installation hole is provided on the cover plate body, and a first electrode assembly is fixedly connected in the installation hole.

[0005] The enclosure is a closed structure that is fixedly connected to the top surface of the cover plate or integrally formed.

[0006] The first electrode assembly includes an electrode body and an insulating component. The electrode body is generally T-shaped and is fixedly connected in the mounting hole. The insulating component is fixedly connected in the gap between the electrode body and the mounting hole to form a closed structure.

[0007] The insulating component includes an upper insulating component and a lower insulating component; the upper insulating component includes an upper gasket and an annular upper flange disposed at the bottom of the upper gasket.

[0008] The upper gasket abuts against the top surface of the cover plate body, and the annular upper flange passes through the mounting hole.

[0009] The upper gasket has a first through hole on its inner surface corresponding to the annular upper flange. A fitting groove is provided outside the first through hole. An aluminum substrate is fitted and installed inside the fitting groove. A second through hole is provided inside the aluminum substrate corresponding to the first through hole.

[0010] The fitting groove includes a set of symmetrically arranged arc grooves and a set of symmetrically arranged straight grooves, with the arc grooves and straight grooves arranged alternately; the bottom of the aluminum substrate is provided with a fitting plate that matches the structure of the fitting groove.

[0011] The lower insulating component includes a lower gasket and an annular lower flange disposed on the top of the lower gasket. The lower gasket abuts against the bottom surface of the cover plate body, and the annular lower flange passes through the mounting hole.

[0012] A battery cover plate further includes a lower plastic component, which is disposed on the bottom surface of the cover plate body. A cap is installed on the bottom surface of the lower plastic component corresponding to the liquid injection hole. A connecting hole is opened on the cap corresponding to the liquid injection hole. A connecting through hole is opened on the upper surface of the lower plastic component corresponding to the mounting hole. The diameter of the connecting through hole is larger than the diameter of the mounting hole and smaller than the diameter of the lower part of the electrode body.

[0013] The beneficial effects of this invention are as follows: This invention provides a battery cover. In use, this invention improves upon existing electrolyte injection holes by adding a containment structure. This effectively prevents electrolyte from overflowing from the injection hole when electrolyte is injected into the battery, as the top surface of the injection hole is flush with the top surface of the cover body. This solves the problem of electrolyte residue on the cover body due to overflow and also eliminates the pollution of the workshop environment by flammable and volatile electrolyte, as well as related safety hazards, greatly improving safety. Furthermore, the first electrode assembly of this invention uses an insulating component to reliably seal the electrode body, effectively preventing electrolyte leakage from inside the battery and preventing leakage during transportation and... During non-static use, electrolyte leakage occurs, thus ensuring battery safety. Furthermore, this invention effectively simplifies the battery cover structure without increasing the overall battery height, allowing for a thinner cover and increased battery energy density. Finally, the lower plastic component reduces friction between the cover and battery, preventing damage due to excessive installation pressure. During discharge, an electric arc is generated between the battery and the contact block; the lower plastic component prevents this arc, increasing battery safety and directly ensuring the battery's own safety. This invention offers advantages such as simple structure, ease of use, prevention of electrolyte leakage, and elimination of safety hazards. Attached Figure Description
