Novel power battery cover plate assembly structure

Abstract

The invention discloses a novel power battery cover plate assembly structure. The structure comprises a power connection terminal and a cover plate structural member, the power connection terminal comprises upper plastic, a metal ring and a pole, and the upper plastic, the metal ring and the pole are all of a circular structure; the upper plastic is provided with an embedded channel, and the embedded channel is arranged around the upper plastic; the metal ring is provided with a containing cavity, the pole is placed in the containing cavity, a clamping ring is arranged at the top of the metalring, and the clamping ring is inserted into the embedded channel; and the cover plate structural member comprises a substrate and a lower insulating sheet. The lower insulating sheet is provided withan insertion block. A clamping hole is formed in the substrate and correspond to the insertion block in position; the top of the insertion block is provided with a clamping part protruding outwards,the end face of the clamping part is an inclined face, and the insertion block is clamped in the clamping hole through the clamping part so that the substrate and the lower insulating sheet can be assembled into a whole. The structure has the advantages of simple structure, compact matching, reasonable design and the like; therefore, the structure is a product with excellent technical and economicperformances.

Problems solved by technology

[0002] With the gradual heating up of the electric vehicle industry, driving the development of the lithium-ion battery industry, the application of power lithium-ion batteries is becoming more and more extensive, and the battery cover is an important part of the power battery; the battery cover has electrical terminals, traditional The processing technology is to preset the terminal position on the battery cover, add each component of the electrical terminal to the terminal position one by one, and encapsulate the electrical terminal on the battery cover by injection molding, welding or riveting. The process steps are cumbersome, and deviations in the production process will inevitably lead to an increase in the rate of defective products, affecting production efficiency and increasing the burden on the enterprise; at the same time, the traditional processing method needs to be fixed from the inside of the battery cover when the final part of the battery terminal is fixed. Sealing increases the difficulty of processing; in view of this, it is necessary for us to propose a new packaging structure to reduce the difficulty of assembly of the power battery cover
