Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0013] An explosion-proof power lithium battery cover, such as figure 1 As shown, the cover plate body 1 is included, and the cover plate body 1 is arranged horizontally. The cover plate body 1 is punched upward with a boss, and the boss includes a boss top wall 3. Boss side wall 2 is airtightly and fixedly connected to the bottom of the 3 circle, and the boss side wall 2 is vertically arranged, and the lower end of boss side wall 2 is airtightly and fixedly connected with cover plate body 1; explosion-proof marks 4 are engraved on the top wall 3 of the boss . In this embodiment, the thickness of the boss top wall 3 is smaller than the thickness of the boss side wall 2 and also smaller than the thickness of the cover body 1 . There are extruded strips 5 on the edge of the boss top wall 3 .

[0014] In the present invention, the cover body is first...

Abstract

The invention provides an explosion-proof power lithium battery cover plate. The cover plate comprises a cover plate body which is arranged horizontally; a boss is upward stamped on the cover plate body, and comprises a boss top wall which is horizontally arranged; a boss lateral wall is fixedly connected with the lower side of the periphery of the boss top wall in a closed manner, and is vertically arranged; the lower end of the boss lateral wall is fixedly connected with the cover plate body in a closed manner; and explosion-proof marks are engraved in the boss top wall; the thickness of the boss top wall is less than that of the boss lateral wall, and less than that of the cover plate body; and extrusion strips are arranged on the edge of the boss top wall. The power lithium battery explosion-proof cover plate is of an integrated structure, enables the boss to be molded by adopting a stretching way, and is simple in structure and easy to process. The structure of the cover plate is not provided with explosion-proof holes, do not have liquid leakage, the depth of the explosion-proof marks can be easy to control, and compared with the mode of riveting or soldering an explosion-proof die, the explosion proofing of the cover plate is more stable.

Description

technical field [0001] The invention relates to a battery cover, in particular to an explosion-proof power lithium battery cover. Background technique [0002] At present, the explosion-proof structure of the power lithium battery cover plate used in the market is to first punch a central positioning step hole on the cover plate body, then weld or rivet the explosion-proof membrane in the step hole, and finally make explosion-proof marks on the explosion-proof membrane. , This structure is complex to process, prone to liquid leakage, and unstable in explosion-proof. Contents of the invention [0003] The purpose of the present invention is to provide an explosion-proof power lithium battery cover plate with simple structure and good use effect. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] An explosion-proof power lithium battery cover plate, including a cover plate body, the cover plate body is arranged horizo...
