Reinforcement structure of automobile dash panel

Abstract

The invention discloses a reinforcement structure of an automobile dash panel. According to the reinforcement structure of the automobile dash panel, when collision energy is absorbed through collapse of a front longitudinal beam in frontal collision of an automobile, the backward intrusion deformation of the dash panel can be effectively reduced. The reinforcement structure comprises an auxiliary force guide component and a main force guide component, wherein the auxiliary force guide component is arranged between the front longitudinal beam and the dash panel, and the main force guide component is arranged between a column A and the front longitudinal beam. The auxiliary force guide component and the front longitudinal beam are located on the same side of the dash panel, the auxiliary force guide component is located on the outer side of the front longitudinal beam, and the main force guide component and the auxiliary force guide component are located on the two opposite sides of the front dash panel. The front of the auxiliary force guide component is connected with the outer side face of the front longitudinal beam, and the back of the auxiliary force guide component is connected with the dash panel. The side face, facing the dash panel, of the main force guide component is connected with the dash panel, and the main force guide component extends upwards obliquely from the root of the front longitudinal beam to the back along the dash panel and is connected with the lower end of the column A.

Description

technical field [0001] The invention relates to the field of vehicle body structures, in particular to a reinforcement structure for an automobile front panel. Background technique [0002] The quality of automobile body structure design directly affects the safety performance of the whole vehicle. When a car collides, it is required to minimize the deformation of the body and ensure the living space of the driver and passengers to the greatest extent. The front wall of the car refers to the partition between the engine compartment and the compartment, which is connected with the floor and the front pillar. As an important part of the vehicle body, the dash panel needs to control the deformation of the dash panel within a certain range in the event of a frontal collision to ensure the living space of the front row drivers and passengers. [0003] Due to the weak structural strength of the front wall of the car, and when the current car front wall is impacted, the impact fo...

Problems solved by technology

[0003] Due to the weak structural strength of the front wall of the car, and when the current car front wall is impacted, the impact force cannot be effectively transmitted to the rear of the vehicle body, so the impact resistance of the front wall is weak, and it is easy to produce deformation

During a frontal collision of a car, when the collision energy is absorbed through the collapse of the right front side beam and the left front side beam, it is easy to cause excessive intrusion and deformation of the front wall panel, resulting in a huge living space for the front row drivers and passengers. reduced, thus posing a threat to the safety of drivers and passengers

[0004] In order to reduce the amount of deformation of the dash panel when it is impacted, at present, the structural strength and rigidity of the dash panel itself are usually improved to improve the deformation of the dash panel when it is hit; although the structural strength and stiffness of the dash panel itself are strengthened To a certain extent, it can reduce the deformation of the dash panel when it is impacted; however, when the dash panel is impacted, the impact force is mainly borne by the dash panel itself, which cannot be effectively transmitted; plus the dash panel The board is plate-shaped and has a large area; therefore, the effect of improving the deformation of the dash board when it is hit by strengthening the structural strength of the dash board itself is not obvious

During a frontal collision of a car, when the collision energy is absorbed through the collapse of the right front side beam and the left front side beam, it is also easy to cause excessive intrusion and deformation of the front wall panel, resulting in a huge living space for the front row drivers and passengers. reduced, thus posing a threat to the safety of drivers and passengers
