Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] Refer to attached figure 1 And attached figure 2 , The first embodiment of the present invention is an electric vehicle battery case upper cover.

[0027] An upper cover of an electric vehicle battery box, comprising a box cover body (1), the box cover body (1) including five surfaces, one top surface (2), and four top surfaces (2) connected together A side wall surface (3), the four corners of the top surface (2) are R-angle transitions, which are top R-angle corners (4), and the top surface (2) and the four side wall surfaces ( 3) The connected part is an R-angle transition, which is the top facing corner (5), and the connection between the four side wall surfaces (3) is an R-angle transition, which is a side wall R-angle corner (6). The bottoms of the four side wall surfaces (3) are flanging structures, and the bead (7) is pasted together with the flangin...

Abstract

The invention relates to an electric automobile battery box upper cover. The electric automobile battery box upper cover comprises a box cover body, the box cover body comprises five surfaces including a top surface and four side wall surfaces connected with the top surface; four corners of the top surface are in R-angle transition and are top R-angle corners; the positions where the top surface are connected with the four side wall surfaces are in R-angle transition and are top straight-surface corners; and the positions where the four side wall surfaces are connected are in R-angle transition and are side wall R-angle corners. According to the electric automobile battery box upper cover, right-angled connection between the top cover and the side walls and right-angled connection betweenthe side walls are corrected into R-angle transition, due to structure change, a processing technology is adjusted, the process is changed into primary stretching from the original forming and welding, thus, the production efficiency of the product is improved, the product is stable, and the repair rate is low.

Description

technical field [0001] The invention relates to the field of electric vehicle batteries, in particular to an electric vehicle battery case upper cover. Background technique [0002] At present, the structure of the upper cover of the electric vehicle battery box has four side wall turning angles at right angles, four top turning angles at right angles, and four flange turning angles at right angles. . Due to the structural design of the original product with right-angle defects, the production process cannot be changed. The best production process can only use the tailor welding method. However, since the forming is an open form, the four corners after forming must be welded to ensure the sealing requirements. Due to The material is thin, and it is easy to weld through the product during welding, resulting in that the sealing cannot be guaranteed. Since the weld bead affects the appearance of the product after welding, it is necessary to grind the welded product. During th...
