Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention will be further described:

[0032] Figure 1 to Figure 5 It shows a rear jack reinforcement structure of an automobile body, including a side wall outer panel 2, a door sill rear connection plate 3 and a door sill rear section 4, and a jack reinforcement plate 5 is added between the door sill rear section 4 and the door sill rear connection plate 3, By adding the jack reinforcing plate 5, the load of the side wall outer panel 2 can be effectively shared, and the serious deformation of the side wall outer panel 2 due to a large load can be avoided when the jack is used. Car body jack supporting point 1 and jack work together. figure 2 It is a schematic diagram of the A-A section in the overall schematic diagram of the car body jack reinforcement structure. The jack reinforcement plate 5 is first welded with the door sill rear connection plate 3 and connected by spot welding. The jack reinforcing pl...

Abstract

The invention relates to a rear jack reinforcing structure for a vehicle body. The reinforcing structure comprises a side wall outer plate (2), a threshold rear connecting plate (3) and a threshold rear segment (4). A jack reinforcing plate (5) is arranged between the threshold rear segment (4) and the threshold rear connecting plate (3); the jack reinforcing plate (5) is of an L-shaped structure; two locating holes (51) are formed in one side of the L-shaped structure; a concave type surface (52) is formed between the two locating holes (51); two double-layer welding spots are arranged on the concave type surface (52), to connect the threshold rear connecting plate (3) with the jack reinforcing plate (5), and four welding spots are arranged on the other side of the L-shaped structure, to connect the side wall outer plate (2), the jack reinforcing plate (5) and the threshold rear segment (4); a U-shaped notch (31) is formed in the welding face, corresponding to the jack reinforcing plate (5), of the threshold rear connecting plate (3); the welding edge, at a vehicle body jack supporting point (1), of the side wall outer plate (2) is shortened upwards than the welding edge of other positions in the height direction.

Description

technical field [0001] The invention belongs to the technical field of automobile body structures, and in particular relates to a rear jack reinforcement structure of an automobile body. Background technique [0002] With the rapid development of the automobile industry, automobiles have become a very common product in our lives. The body jack structure is the main component of the lower body. In the process of using the jack to support the whole vehicle and replace the spare tire, the body jack structure needs to have sufficient strength to bear a certain load, so as to ensure that the body sheet metal parts will not be severely deformed or even damaged. , affecting the appearance and service life of the body. [0003] In order to improve the strength performance of the rear jack structure of the car body, the commonly used methods are: changing the material or material thickness of the car body parts related to the rear jack structure, adjusting or increasing the number a...
