Problems solved by technology

[0002] At present, the B-pillar reinforcement plate structure of automobiles is mostly an integral structure. In order to meet the requirements of side collision, reinforcement plates are usually added to the reinforcement plate structure to achieve the purpose of strengthening the structure. However, the structure of the reinforcement plate of this structure is relatively complicated. The solder joints of the assembly are difficult to realize, and it brings great inconvenience to the electrophoresis and lightweight of the body; if high-strength materials are used, the structure can be greatly simplified, and the electrophoresis and lightweight of the body can be significantly improved, but the cost is high, so it cannot Meet the requirements of fleet cost control

Embodiment Construction

[0014] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. Detailed instructions:

[0015] as attached figure 1 , attached figure 2 As shown, the present invention is a B-pillar reinforcement plate structure of an automobile. The reinforcement plate structure includes an upper reinforcement plate 1 and a lower reinforcement plate 2, and both the upper reinforcement plate 1 and the lower reinforcement plate 2 are arranged in a “U” shape in section. structure, the bottom of the upper reinforcing plate is welded and connected with the top of the lower reinforcing plate.

[0016] The two sides of the upper reinforcing plate 1 are respectively provided with a left bending part I3 and a right bending par...

Abstract

The invention provides a reinforcing plate structure of an automobile column B, and belongs to the technical field of automobile body parts. The reinforcing plate structure comprises an upper reinforcing plate (1) and a lower reinforcing plate (2), the upper reinforcing plate (1) and the lower reinforcing plate (2) are set to be of a structure with a U-shaped section, and the lower end portion of the upper reinforcing plate (1) is connected with the upper end portion of the lower reinforcing plate (2) in a welding mode. According to the reinforcing plate structure, stress in the side impact process can be concentrated on the lap-jointpositionof the upper reinforcing plate and the lower reinforcing plate, therefore, the problem that the intrusion amount of the upper portion of the reinforcing plates is large in the side impact process is solved, the side impact performance of the reinforcing plates of the column B is improved, and the aim of reducing hurt to the human body by side impacts is achieved. Meanwhile, the reinforcing plate structure is simple in structure, low in cost and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of automobile body components, and more specifically relates to an automobile B-pillar reinforcement plate structure. Background technique [0002] At present, the B-pillar reinforcement plate structure of automobiles is mostly an integral structure. In order to meet the requirements of side collision, reinforcement plates are usually added to the reinforcement plate structure to achieve the purpose of strengthening the structure. However, the structure of the reinforcement plate of this structure is relatively complicated. Assembly solder joints are difficult to realize, and it brings great inconvenience to body electrophoresis and lightweight; if high-strength materials are used, the structure can be greatly simplified, and body electrophoresis and lightweight can be significantly improved, but the cost is high, so it cannot Meet the team's vehicle cost control requirements.
