Abstract

The invention provides an automobile roof crossrail connecting structure, which is applied to the technical field of automobile body parts. A roof crossrail assembly (1) of the automobile roof crossrail connecting structure comprises a roof crossrail body (4) and a roof crossrail reinforcing plate (5); a plurality of protruded protrusion parts I (6) are arranged on the roof crossrail body (4), andprotrusion parts II (7) corresponding to the protrusion parts I (6) one to one in position and number are arranged on the roof crossrail reinforcing plate (5); and the weld connected part of the outer side surface of the roof crossrail reinforcing plate (5) and a body-side inner plate (3) coincides with the welded part of an inner plate (2) of a column B and the inner side surface of the roof crossrail reinforcing plate (5). According to the automobile roof crossrail connecting structure, by changing structures and mutual connecting relations and connection positions of the parts such as theroof crossrail assembly and the body-side inner plate, the connecting rigidity between a roof crossrail and the body side is effectively improved, the automobile body strength is improved, and personal safety of personnel in an automobile is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile body parts, and more specifically relates to an automobile roof beam connection structure. Background technique [0002] In the automobile body structure in the prior art, the structural connection between the roof beam and the side wall inner panel is only through several welding points. Such a structure results in weak connection stiffness between the roof beam and the side wall, which is not conducive to roof stiffness and modal control, resulting in connection defects in the body structure, and cannot effectively protect the personal safety of the occupants in the event of a car accident. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple structure in view of the deficiencies of the prior art, by changing the structure of components such as the top cover beam assembly and the side wall inner panel, as well as their mutu...
