Abstract

The invention provides a connecting structure of an front cross beam and a side wall assembly of an automobile roof, and belongs to the technical field of automobiles. The problem that the collision performance of the joint of an existing automobile roof front cross beam and a side wall assembly is poor is solved. The connecting structure comprises a connecting plate and a skylight reinforcing plate fixedly connected with the roof front cross beam, the connecting plate is provided with a base plate located on the lower side of the roof front cross beam and welded to the roof front cross beam,and the skylight reinforcing plate is provided with a longitudinal part extending in the front-back direction of an automobile body. The longitudinal part is provided with a main plate body arranged in the height direction of an automobile body, an extending plate body extending towards the rear side of the automobile body is connected to the base plate, the longitudinal part is welded to t he inner plate of the upper edge beam at the upper edge of the main plate body, and the longitudinal part is welded to the inner side edge of the extending plate body at the lower edge of the main plate body. And the outer side edge of the extending plate body is welded with a roof side rail inner plate. According to the invention, the automobile has good head-on collision performance and small offset collision performance.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a connection structure between a front beam of an automobile roof and a side wall assembly. Background technique [0002] With the development of science and technology and the improvement of people's living standards, cars have entered thousands of households and become the most important means of transportation for people's daily travel. The safety of a car is an important parameter for users to choose a car, and improving the crash performance of a car body has become an inevitable trend in the development of cars. [0003] The front cross beam of the car roof is supported on the lower side of the car roof along the lateral direction of the car. Whether the connection between the front cross beam of the car and the side panel assembly is reliable will directly affect the frontal collision performance and small offset collision performance of the car. [0004] At present, th...
