White car body frame assembly

Abstract

The invention discloses a white car body frame assembly. The white car body frame assembly comprises a car body frame body, a front end frame and two side wall frames, wherein the front end frame is fixed to the front side of the car body frame body; the two side wall frames are fixed onto the left and right side faces of the car body frame body respectively; the left and right ends of the front end frame are fixedly connected with the front ends of the two side wall frames respectively; the front end frame comprises two upper bending beam upright post reinforced plates; and the two upper bending beam upright post reinforced plates extend from top to bottom respectively to be fixed to the rear sides of corresponding car body upper bending beam upright posts. The white car body frame assembly disclosed by the invention solves the problem that the connection between the upper bending beam upright posts and front longitudinal beams is weak, front face column collision longitudinal beams do not collide, the front face column collision performance is improved, moreover, the rigidity of headlamp mounting points is increased, and the safety of passengers is improved.

Description

technical field [0001] The invention relates to a body-in-white frame assembly, in particular to a body-in-white frame assembly for strengthening the connection strength of a body-in-white. Background technique [0002] The body-in-white frame assembly is the main body of the vehicle to bear the load and resist the impact of collisions. Its design plays a decisive role in the strength, stiffness, mode, safety, durability and other performance of the vehicle body, and directly affects the user's riding experience and subjective feelings. Currently, common body-in-white frames for passenger vehicles, such as figure 1 As shown, the vehicle body front-end frame A', front wheel housing assembly B', side wall frame C', door sill assembly E' and front wheel housing support assembly D' are connected to form, and the front-end frame A' (such as Figure 1a ) includes: upper curved beam column 10' and front longitudinal beam 11', front wheel house assembly B' (such as Figure 1b ) in...

AI Technical Summary

Problems solved by technology

[0009] The present invention is completed in order to solve the deficiencies in the prior art. The purpose of the present invention is to provide a solution to the problem of the weak connection between the upper curved beam column and the longitudinal beam, to realize that the front column collides with the longitudinal beam without participating in the collision, and improves the front column collision. performance while increasing the stiffness of the headlight mounting points and improving occupant safety in the body-in-white frame assembly
