Embodiment 1

[0018] Such as figure 1 As shown, the new energy battery cover plate of the present invention that is easy to disassemble includes a cover plate body 1, a groove is opened on the bottom surface of the cover plate body 1, a first explosion-proof diaphragm 2 is fixed at the groove opening, and a first explosion-proof diaphragm 2 is fixed on the cover plate body 1. There is also a buffer port 3 on the plate body 1, and the buffer port 3 communicates with the inside of the groove, and a second explosion-proof diaphragm 4 is also arranged on the surface that the buffer port 3 contacts with the inside of the groove. The explosion-proof diaphragm 2 and the second explosion-proof diaphragm 4 encircle the inside of the groove to form an explosion-proof buffer chamber 5; on the bottom surface of the cover plate body 1, a circle of annular convex strips 6 is also arranged, and the outer wall of the annular convex strips 6 is provided with thread. The present invention just passes throug...

Embodiment 2

[0020] Such as figure 1 As shown, on the basis of Example 1, the thickness of the first explosion-proof diaphragm 2 is 1.5 mm.

Embodiment 3

[0022] Such as figure 1 As shown, on the basis of Example 1, the thickness of the second explosion-proof diaphragm 4 is 2mm.

Abstract

The invention discloses a new energy battery cover plate convenient in assembling. The new energy battery cover plate comprises a cover plate body, wherein the bottom of the cover plate body is provided with a groove; a first anti-explosion diaphragm is fixed in a groove opening; the cover plate body is also provided with a buffer hole; the buffer hole is communicated with the inner side of the groove; the surface, which is in contact with the inner part of the groove, of the buffer hole is provided with a second anti-explosion diaphragm; the first anti-explosion diaphragm and the second anti-explosion diaphragm surround the inner part of the groove to form an anti-explosion buffer cavity; the bottom surface of the cover plate body is also provided with one ring of annular convex strip; the outer wall of the annular convex strip is provided with a thread. According to the new energy battery cover plate, the problems that a traditional new energy battery cover plate is difficult in installation and disassembling and a pressure-relief anti-explosion function can not be performed on the new energy battery.

Description

technical field [0001] The invention relates to a battery cover, in particular to a new energy battery cover that is easy to assemble and disassemble. Background technique [0002] With the development of new energy battery technology, various new batteries have begun to be widely used. However, the existing new battery cover is difficult to install and disassemble, and it is prone to short circuit when the new battery collides. The existing new battery cover cannot play the role of pressure relief and explosion protection for the new battery, so we make improvements to this . Contents of the invention [0003] The purpose of the present invention is to provide a new energy battery cover plate that is easy to disassemble, which can effectively solve the problems that the existing new energy battery cover plate is difficult to install and disassemble and cannot play the role of pressure relief and explosion protection for the new energy battery. [0004] The present inven...
