Roof frame installation structure and car comprising same

Abstract

The invention relates to a roof frame installation structure. A roof side rail (3) of the roof frame is fixed on a side wall roof rail (4) of a side wall frame along the longitudinal direction of the car, wherein the roof frame installation structure also comprises a support member (5), the support member (5) is fixed on the side wall roof rail (4) and a roof cross rail (1) of the roof frame from the inner part of the car, and the support member and the roof cross rail (1) are located in the same cross section of the car. The technical scheme of the invention can obviously increase the rigidity and the strength of the upper structure of a body frame, so that the roof frame of the car can be prevented from seriously deforming toward the inner part of the car when a side turnover accident occurs to the car so as to ensure the safety of passengers.

Description

technical field [0001] The invention relates to an automobile roof frame installation structure. In addition, the present invention also relates to an automobile comprising the roof frame installation structure. Background technique [0002] Automobile (such as passenger cars, commercial vehicles, etc.) skeletons generally include front wall frames, rear wall frames, left and right side wall frames, floor frames, and roof frames. Among them, the traditional installation structure of the roof frame is as follows: figure 1 and figure 2 As shown, the roof beam 1 of the roof frame is connected to the roof side beam 3, and the roof side beam 3 is further welded to the side wall upper longitudinal beam 4 of the side wall frame along the longitudinal direction of the vehicle. In order to improve the supporting effect of the side frame on the roof frame, the roof beam 1 of the roof frame and the corresponding side column 2 of the side frame are generally in the same cross sectio...

AI Technical Summary

Problems solved by technology

[0003] However, there are two major disadvantages in the traditional mounting structure of the roof frame: first, although the traditional mounting structure can basically guarantee the supporting effect on the roof frame during the normal running of the car, when the car rolls over, The top of the car, especially the roof frame, is often directly impacted by the ground (especially the ground protrusions), so the deformation of the upper part of the car body will be large, which often causes the roof frame to deform severely to the inside of the car, and thus causes the roof to be damaged. The frame and its beams intrude into the interior space of the car where the occupants are located. This will cause the occupants to collide with the intruded roof frame and its beams when the car rolls over and the occupants seriously lose their balance. Injure or even kill the passengers, seriously threatening the safety of the occupants; second, the traditional roof installation structure is essentially a rigid connection structure

Since the connection between the roof frame and the side frame is rigid, it cannot absorb vibrations, and the side frame is rigidly connected to the floor frame or the frame, so the roof frame will repeatedly pull and compress the side frame Skeleton, this pulling force and compression force will be converted into rapid and severe micro-vibration of the side frame, which will cause the side window glass installed on the car side frame to vibrate sharply, affecting the ride comfort of the car
