Problems solved by technology

The existing side wall reinforcement plate needs to develop molds and inspection tools for each component separately, and also needs to develop fixtures and welding equipment to weld the components. More welding points need to be added to the connection parts to ensure the connection strength, resulting in weight and production costs. cost increase
In addition, on the one hand, there is stress concentration at the welding position of the front reinforcement plate of the side wall, and the force transmission effect becomes poor;

Embodiment 1

[0026] see figure 1 , figure 1 The side wall AB pillar reinforcement panel assembly provided for the present invention includes an A-pillar reinforcement panel 10 , a B-pillar reinforcement panel 20 , and a rocker reinforcement panel 30 .

[0027] The A-pillar reinforcement plate 10 includes an A-pillar upper reinforcement plate 101 and an A-pillar lower reinforcement plate 102. The A-pillar upper reinforcement plate 101 extends upward and obliquely from the front to the rear of the vehicle, and the A-pillar lower reinforcement plate 102 extends from the front to the rear of the vehicle first. Extending downward and horizontally backward, the lower end of the A-pillar upper reinforcing plate 101 is connected with the upper end of the A-pillar lower reinforcing plate 102 .

[0028] The B-pillar reinforcement plate 20 includes a B-pillar upper reinforcement plate 201 and a B-pillar lower reinforcement plate 202. The B-pillar upper reinforcement plate 201 is T-shaped and include...

Embodiment 2

[0034] see figure 2 , figure 2 The side wall ABC pillar reinforcement plate assembly provided for the present invention is installed in a car with high safety requirements and intensive production requirements, and the side beam is added on the basis of the side wall AB pillar reinforcement plate assembly in Example 1 Reinforcement panel 40 and C-pillar reinforcement panel 50 .

[0035] The C-pillar reinforcement plate 50 includes a C-pillar upper reinforcement plate 501, a lock reinforcement plate 502, and a C-pillar lower reinforcement plate 503. The C-pillar upper reinforcement plate 501 includes a fifth connecting plate 501a extending from the front to the rear and connecting with the fifth The connecting plate 501a is connected to the sixth connecting plate 501b extending toward the bottom of the vehicle. The sixth connecting plate 501b is connected to the front end side of the fifth connecting plate 501a. The fifth connecting plate 501a is the upper end of the C-pilla...

Embodiment 3

[0038] see image 3 , image 3 The side wall ABCD pillar reinforcement plate assembly provided for the present invention is installed in automobiles with higher safety requirements and higher intensive production requirements, and the D-pillar reinforcement plate is added on the basis of the side wall ABC pillar reinforcement plate in Example 2 60 and CD column reinforcement plate connecting plate 70.

[0039] When manufacturing the ABCD pillar reinforcement plate assembly of the side wall, the joint of the A-pillar upper reinforcement plate 101 and the A-pillar lower reinforcement plate 102 is laser tailor-welded, and the junction of the B-pillar upper reinforcement plate 201, the hard area 202a, and the transition area 202b is laser welded. Welding, C-pillar upper reinforcement plate 501, lock reinforcement plate 502, and C-pillar lower reinforcement plate 503 joint laser tailor welding, the upper end of A-pillar upper reinforcement plate 101 and the first connecting plate ...

Abstract

A side wall reinforcing plate assembly comprises an A-pillar reinforcing plate, a B-pillar reinforcing plate, a doorsill reinforcing plate, an upper edge beam reinforcing plate and a C-pillar reinforcing plate, the upper end of the A-pillar reinforcing plate and the front end of the upper end part of the B-pillar reinforcing plate are subjected to tailored blank laser welding, the lower end of theA-pillar reinforcing plate and the front end of the lower end part of the doorsill reinforcing plate are subjected to laser tailor welding, the lower end part of the B-pillar reinforcing plate and the upper end part of the doorsill reinforcing plate are subjected to laser tailor welding, the rear end of the upper end of the B-pillar reinforcing plate is welded to the front end of the upper edge beam reinforcing plate in a laser tailor-welded mode, the rear end of the upper edge beam reinforcing plate is welded to the front end of the upper end of the C-pillar reinforcing plate in a laser tailor-welded mode, and the lower end of the C-pillar reinforcing plate is welded to the rear end of the lower end of the threshold reinforcing plate in a laser tailor-welded mode. According to the side wall reinforcing plate assembly, the problems that an existing side wall reinforcing plate cannot meet the safety requirement and is poor in weight, and spot welding is still needed are solved. The invention further provides a vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing and design, in particular to a side wall reinforcement plate assembly and a vehicle with the same. Background technique [0002] The side wall reinforcement plate structure of an automobile plays a vital role in the collision safety of the vehicle. The existing front side wall reinforcement plates are generally divided into A-pillar lower reinforcement plates, upper side beam reinforcement plates, B-pillar reinforcement plates and door sill reinforcement plates. , After the above four parts are hot stamped and formed separately, they are connected together by spot welding. The existing side wall reinforcement plate needs to develop molds and inspection tools for each component separately, and also needs to develop fixtures and welding equipment to weld the components. More welding points need to be added to the connection parts to ensure the connection strength, resulting in weigh...
