Description

A light truck cab front wall assembly

technical field

The invention belongs to the technical field of automobiles, and in particular relates to a front wall assembly of a cab of a light truck.

Background technique

The front wall assembly is an important part of the cab, mainly to ensure the torsional rigidity of the body, improve the collision safety, and control the rearward displacement of the front wall of the cab after a collision. The structural design of the front wall assembly should not only meet the functional requirements for the installation of accessories, but also improve the manufacturability so that it has good welding performance on the production line; Safety. At present, the structure of the front wall of the light truck cab is relatively simple, and its strength is relatively weak, which cannot meet the relevant regulations on the protection of commercial vehicle occupants, and the anti-dent and rigidity cannot meet the requirements.

Contents of the invention

The purpose of the present invention is to provide a light truck cab cowl assembly technical solution. Through this technical solution, the rigidity and strength of the existing light truck cab cowl assembly are weak, and it is impossible to ensure that the occupants have enough space after a frontal collision. The problem of living space.

The present invention is achieved through the following technical solutions:

A light-duty truck cab front wall assembly, comprising a front wall outer panel, a bracket fixed on the left side panel of the front panel outer panel, a bracket fixed on the right side panel of the front panel outer panel, and a bracket fixed on the front panel outer panel The front wall reinforcement panel assembly on the inner side acts as a skeleton; a gap is provided between the front wall outer panel and the front wall reinforcement panel.

The outer surface of the dash outer panel protrudes outward.

The cowl reinforcement plate assembly is composed of a cowl upper reinforcement plate assembly, a cowl inner panel assembly, a cowl middle reinforcement plate and a cowl side reinforcement plate; The upper end of the outer panel is fixedly connected, and the lower end is fixedly connected with the upper end of the dash inner panel assembly; the dash inner panel assembly is also fixedly connected to the upper end of the dash center reinforcement board and the dash side reinforcement board; The lower end of the side reinforcing plate is fixedly connected to the lower end of the dash outer panel and welded to the floor at the same time.

The inner surface of the dash outer panel, the inner surface of the upper dash reinforcement panel assembly and the inner surface of the upper part of the dash inner panel assembly together form an upper cavity structure; the inner surface of the dash outer panel and the dash inner panel assembly The inner surfaces of the lower parts jointly enclose the lower cavity structure.

The gap between the front wall outer panel and the front wall reinforcing plate is 3-5mm.

The gap is filled with shock-absorbing glue.

The beneficial effect of the present invention compared with prior art is:

1. The structure of the front wall assembly of the existing light truck cab has been improved in a targeted manner, its stiffness and strength have been effectively improved, and the collision safety performance has been improved.

2. Two obvious cavity structures are formed through the technical solution of the present invention, which improves the strength of the entire cowl assembly, ensures full absorption of impact energy during a frontal collision, and reduces the collapse and deformation of the cowl.

Detailed ways

The technical solutions of the present invention are described in detail below through examples. It should be understood that the following examples can only be interpreted as explanations and descriptions of the technical solutions of the present invention and cannot be interpreted as limitations on the technical solutions of the present invention.

The inner side and the outer side mentioned in the present invention are relative concepts, which conform to the common understanding of those skilled in the art; the left side and the right side refer to the left side and the right side when facing the front view of the dash outer panel; The above and below are relative concepts, which are only used to describe the technical solution of the present invention.

Referring to Fig. 1 and Fig. 2, a front wall assembly of a cab of a light truck includes a front wall outer panel 1 protruding outward from the outer surface, a bracket 2 on the left side plate fixed on the front wall outer panel, and fixed on the front wall outer panel. The four parts of the bracket 3 on the right side of the plate and the front wall reinforcement plate assembly 4 are formed by tailor welding of each component on the welding fixture. The cowl assembly is a frame structure, the cowl stiffener assembly 4 acts as a skeleton, the dash outer panel 1 covers the outer surface of the cowl stiffener assembly 4, the gap between the two is 3 mm, and the coat is coated with Shock-absorbing rubber, after the expansion, the front wall assembly forms a space structure with anti-dent, anti-vibration and anti-impact.

Referring to FIG. 3 , the dash reinforcement panel assembly 4 is formed by welding the dash upper reinforcement panel assembly 5 , the dash inner panel assembly 6 , the dash middle reinforcement panel 7 , and the dash side reinforcement panel 8 . Among them, the dash upper reinforcing plate assembly is fixedly connected with the upper end of the dash outer panel, and the lower end is fixedly connected with the upper end of the dash inner panel assembly; the dash inner panel assembly is also fixedly connected with the dash middle stiffening plate and the dash side stiffening plate The upper end of the front wall reinforcement plate and the lower end of the front wall side reinforcement plate are fixedly connected to the lower end of the front wall outer panel and welded to the floor at the same time, which can also disperse and conduct the impact energy during the collision.

Referring to Fig. 4, the sectional view of the front wall assembly, the inner surface of the front wall outer panel, the inner surface of the front wall upper reinforcing plate assembly and the inner surface of the upper part of the front wall inner panel assembly together form an upper cavity structure 10; the front wall The inner surface of the outer panel and the inner surface of the lower part of the dash inner panel assembly together form a lower cavity structure 11; the upper cavity structure and the lower cavity structure communicate through the gap between the dash reinforcement panel assembly and the dash outer panel , the width of the upper cavity structure 10 and the width of the lower cavity structure are much larger than the gap of the void. Through the above structural design, two obvious cavity structures are formed, which improves the strength of the entire front wall assembly, ensures full absorption of impact energy during a frontal collision, and reduces the collapse and deformation of the front wall.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
