Reinforcing structure penetrating front wall board and front floor

Abstract

The invention relates to a reinforcing structure penetrating a front wall board and a front floor. The reinforcing structure comprises a right edge part and a left edge part. The left edge part comprises a front wall board left supporting component, a front floor left front reinforcing piece and an engine compartment left edge beam front section adjacent to the front wall board left supporting component and further comprises the front wall board, the front floor, a front wall board left reinforcing cross beam, an engine compartment left edge beam rear section, a left edge beam rear section outer lining board and a front-row seat installation front cross beam, all of which are connected with the front wall board left supporting component or / and the front floor left front reinforcing piece. The front wall board left supporting component is a box with a strip-shaped opening, and the upper end of the front wall board left supporting component is adjacent to the fork position of the engine compartment left edge beam front section. The opening edge of the front wall board left supporting component is welded to the front wall board, further welded to the left edge beam rear section outer lining board arranged on the lower face of the front floor and the engine compartment left edge beam rear section arranged on the lower face of the front floor in an overlapped manner and further welded to the front wall board left reinforcing cross beam. By the adoption of the reinforcing structure, the problems that the front wall board deforms and the invading amount is too large in the direct impact and bias impact processes can be solved, and the safety of a driver is facilitated.

Description

technical field [0001] The invention relates to a car body, in particular to a reinforcement structure passing through a front wall plate and a front floor. Background technique [0002] At present, the development of new models pays more and more attention to safety performance, and the connection between the front cabin and the front floor directly affects the frontal collision and offset collision performance. CN 201220282124.X discloses "a support structure for front wall panels" and CN 200820176323.6 discloses "body front panel reinforcement structure and vehicle body front panel assembly", the front panel reinforcement structure focuses on the front panel Local reinforcement and support, without mentioning the connection between the reinforcement structure and the frame beam of the vehicle body and the connection with the front part of the front floor, the collision channel is not optimized enough. CN 203372297U discloses "a reinforcing plate for connecting the front ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a reinforcement structure that runs through the front wall and the front floor, which can solve the problems of deformation and excessive intrusion of the front wall in frontal and offset collisions, and is beneficial to the safety of the driver and co-driver. Safety, while taking into account the structure simplification and process optimization
