Problems solved by technology

As mentioned earlier, the strength of the A-pillar itself is generally low. In this case, the A-pillar is easily deformed, resulting in deformation of the cockpit, threatening the safety of the driver and passengers. When the deformation of the A-pillar is serious, It will cause the front door cannot be opened, and the chance of the driver's escape will be reduced

Embodiment Construction

[0017] figure 1 Shown is a schematic diagram of the body A-pillar reinforcement assembly, figure 2 for along figure 1 A cross-sectional view of the body A-pillar reinforcement assembly cut along line A-A in the center.

[0018] Such as figure 1 , figure 2 As shown, the vehicle body A-pillar reinforcement assembly includes an A-pillar reinforcement plate. The A-pillar reinforcement plate is a stamped plate with flanging formed on both sides and bent to form a groove 9 for covering the A-pillar 8 of the vehicle body. . In order to ensure the smooth progress of the stamping process, the A-pillar reinforcement plate is divided into upper and lower sections, that is, the upper section 1 of the A-pillar reinforcement panel and the lower section 4 of the A-pillar reinforcement panel. The upper section 1 of the A-pillar reinforcement panel and the lower section 4 of the A-pillar reinforcement panel are welded firmly connected together. In the groove 9 of the upper part 1 of th...

Abstract

The invention provides an A-column reinforced assembly of a car body. The A-column reinforced assembly of the car body comprises an A-column reinforced plate; a groove (9) for covering the A-column of the car body is formed on the A-column reinforced plate; the A-column reinforced assembly further comprises an upper part front support plate (3) and a lower part back support plate (2) which are fixed at the two corresponding sides of the front side wall (10) of the groove (9). Furthermore, the invention also provides an A-column reinforced structure of the car body by using the A-column reinforced assembly. The A-column reinforced structure of the car body can remarkably increase the strength of the A-column of the car body without influencing the visual field of a driver.

Description

technical field [0001] The invention relates to a vehicle body A-pillar reinforcement assembly. In addition, the invention also relates to a vehicle body A-pillar reinforcement structure using the reinforcement assembly. Background technique [0002] In today's world, cars have become the most important means of transportation. Based on the total population of the world, an average of nine people own one car, among which cars are the most. With the development of society, users have higher and higher requirements for various performances of automobiles, including comfort, aesthetics, entertainment, safety and other performance requirements. In the design of the automobile body, the performance of the A-pillar (i.e. the front pillar of the automobile body) is more difficult to take into account. In a collision, the strength of the A-pillar of the body is very important: first, the A-pillar can reduce the deformation of the cockpit and protect the passengers and the driver; ...
