Abstract

The utility model discloses an aluminum hull apron subassembly with location structure, including casing and the top cap of pegging graft in the casing upper end, still including setting up the locating part on shells inner wall, the locating part moves down from downside restriction top cap after the top cap inserts the casing to fix a position. After the electric core is inserted into the shell, the top cover is covered, the size of the top cover is slightly smaller than that of the shell, the electric core can be inserted into the shell, after the electric core is inserted into the shell, the top cover contacts with the positioning bubble, the electric core moves downwards to meet resistance, stops at the moment, is welded in time, and avoids sliding downwards. The positioning of the positioning bubble avoids the situation that the cover plate moves down too much or not in place, ensures that the top cover is just matched with the shell, and has better welding tightness.

Description

Aluminum shell cover plate assembly with positioning structure

Technical Field

The utility model belongs to the technical field of the location of square aluminum hull apron, especially, relate to an aluminum hull apron subassembly with location structure.

Background

With the development of times, the application of lithium ion batteries is more and more extensive, and in the production process of square aluminum shell lithium ion batteries, after a battery core is placed into a shell, a top cover needs to be welded. And in part, when the battery cell is placed in the shell, the top cover cannot reach the expected position. Or outside location bubble partly, or inside sunken partly, lead to carrying out the top cap welding incomplete, the casing is unable totally enclosed, consequently, how to fix a position when the top cap inserts, guarantees welding quality and is the problem that this field technical staff urgently needed to solve.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an aluminum hull apron subassembly with location structure to solve the problem of background art.

In order to achieve the above object, the utility model discloses an aluminum hull cover plate assembly with location structure's concrete technical scheme as follows: the positioning component is inserted into the shell and limits the top cover to move downwards from the lower side so as to perform positioning.

Further, the positioning component is a positioning bubble.

Furthermore, the positioning bubble is arc-shaped and close to the corner of the shell.

Further, the positioning bubble is formed by punching the outer wall of the shell inwards.

Furthermore, the shell is square, and the positioning bubbles are arranged on the walls of the left inner cavity and the right inner cavity of the shell.

Furthermore, two positioning bubbles are respectively arranged on the left inner cavity wall and the right inner cavity wall of the shell.

Furthermore, the thickness of the positioning bubble is 0.15-0.25 mm.

Furthermore, the diameter of the positioning bubble is 0.8-1.2 mm.

Compared with the prior art, the utility model discloses following beneficial effect has: after the electric core is inserted into the shell, the top cover is covered, the size of the top cover is slightly smaller than that of the shell, the electric core can be inserted into the shell, after the electric core is inserted into the shell, the top cover contacts with the positioning bubble, the electric core moves downwards to meet resistance, stops at the moment, is welded in time, and avoids sliding downwards. The positioning of the positioning bubble avoids the situation that the cover plate moves down too much or not in place, ensures that the top cover is just matched with the shell, and has better welding tightness.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made with reference to the accompanying drawings.

Referring to fig. 1-3, an aluminum cover assembly with a positioning structure comprises a housing 1, a top cover 11 inserted into the upper end of the housing 1, and a positioning member disposed on the inner wall of the housing 1, wherein the positioning member restricts the top cover 11 from moving downward from the lower side after the top cover 11 is inserted into the housing 1, so as to perform positioning. The positioning component is a positioning bubble 2 which is pressed against the downward moving top cover 11 to achieve positioning. Location bubble 2 is convex, and is close to the corner of casing 1, avoids electric core to block. The positioning bubble 2 is formed by inward stamping of the outer wall of the shell 1, and manufacturing is convenient. The shell 1 is square, and the positioning bubbles 2 are arranged on the walls of the left and right inner cavities of the shell 1. The symmetrical arrangement is in both sides, also can not influence the other places that the electricity core was put into. Two positioning bubbles 2 are respectively arranged on the left inner cavity wall and the right inner cavity wall of the shell 1, so that the positioning effect is better. The thickness of the positioning bubble 2 is 0.15-0.25 mm, and if the thickness is too large, the insertion of the battery cell is easily influenced. The diameter of the positioning bubble 2 is 0.8-1.2 mm. Is moderate.

The working principle is as follows: after the electric core is inserted into the shell 1, the top cover 11 is covered, the size of the top cover 11 is slightly smaller than that of the shell 1, the electric core can be inserted into the shell 1, after the electric core is inserted, the top cover 11 contacts the positioning bubble 2, the electric core moves downwards to meet resistance, stops at the moment, is welded in time, and avoids sliding downwards. The positioning of the positioning bubble 2 avoids the situation that the cover plate 11 moves down too much or not in place, ensures that the top cover 11 is just matched with the shell 1, and has better welding tightness.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
