Groove (9), the groove (9) penetrate through top surface (2) surface.
Specifically, press strip (7) material is aluminium.
Specifically, being evenly distributed with hole, hole and institute on the press strip (7) on the press strip (7) and the turnup structure
The hole stated on turnup structure corresponds.
Specifically, described opening (8) surface is evenly arranged with hole.
Specifically, box cover body (1) length is 760mm, width 660mm, it is highly 120mm, with a thickness of
0.7mm。
Specifically, box cover body (1) length is 1058mm, width 660mm, it is highly 120mm, with a thickness of
0.7mm。
Compared with prior art, the present invention realize the utility model has the advantages that by original to electric automobile battery box superstructure
Top right angle portions optimization design be modified as R corner-kick at four angle right angle turns at the top of the transition of the angle R and battery box cover
Shape transition, product top four sides turning are modified as the transition of the angle R by right angle, and four corners of side wall are repaired by original right-angled bend
It is changed to the transition of the angle R, flange face is modified as the transition of the angle R by original right angle with side wall turning, and the variation in structure is so that original
Molding butt welding process be changed to disposable drawing process, after electric automobile battery box superstructure after optimization by designing,
Produce it is following the utility model has the advantages that
1. 20 times or more are promoted in production efficiency in original structure process；
2. repair rate is substantially reduced in terms of quality on original structure, original molding butt welding process repair rate 30% or so, existing one
The disposable qualification rate of secondary property drawing process is greater than 95% or more, and drawn products are stablized, and size and rigging position meet assembly and want
It asks, without being corrected；
3. can directly save two procedures in process in original structure technique, while it can directly reduce welding workstation
The investment of equipment and the investment of operator.
4. upper cover material thickness is thinned to 0.7mm by 0.8mm, press strip is changed to aluminium by iron, can have obvious loss of weight to imitate in weight
Fruit；
5. performance and functionally meeting the requirements, i.e., mode, which reaches, reaches requirement by testing verifying, and sealing performance passes through gas
Close property test reaches requirement with heavy water test, and overall dimensional accuracy is by being able to satisfy requirement after assembly and entrucking verifying.
