Embodiment Construction

[0027] Such as Figure 3 to Figure 7 Shown is a carbon fiber composite automobile rear roof beam assembly structure, the automobile rear roof beam assembly is only composed of the rear roof beam body 1, the back door left hinge reinforcement plate 2 and the back door right hinge reinforcement plate 3, without other redundant parts; the rear roof beam body 1 is fixedly connected to the lower end surface of the vehicle roof 5, and the rear door left hinge reinforcement plate 2 and the rear door right hinge reinforcement plate 3 are fixedly connected to the rear roof beam body 1 End face; the rear top beam body 1, the left hinge reinforcement plate 2 of the back door and the right hinge reinforcement plate 3 of the back door are all carbon fiber composite materials, and the carbon fiber composite material only needs a thickness of 1.5 mm to meet the strength and rigidity requirements.

[0028] Further, in order to better cooperate and connect the rear roof beam body 1, the left h...

Abstract

The invention provides a carbon fiber composite material automobile rear top cross beam assembly structure which consists of a rear top cross beam body, a back door left hinge reinforcing plate and a back door right hinge reinforcing plate, and the rear top cross beam body is fixedly connected with the lower end surface of an automobile body top cover; the back door left hinge reinforcing plate and the back door right hinge reinforcing plate are fixedly connected to the lower end face of the rear top beam body. The rear top beam body, the back door left hinge reinforcing plate and the back door right hinge reinforcing plate are all made of carbon fiber composite materials. The structure solves the problems that the rigidity and strength performance of a traditional rear top beam assembly of the vehicle body cannot meet the requirements, assembly is complex, rusting is prone to occurring, and the practicability and comfort of the whole vehicle are insufficient.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a carbon fiber composite material automobile rear roof beam assembly structure. Background technique [0002] The rear roof beam assembly structure of some automobile models, such as figure 1 with figure 2 As shown, the rear roof beam body, roof rear beam reinforcement plate and rear door left / right hinge reinforcement plate are welded by resistance welding. There are many sub-components in the rear roof beam assembly, too many components to be welded will lead to complicated welding process and difficult to control the quality of components. The components of the traditional rear roof beam assembly are stamped from high-strength cold-rolled steel plates, and are welded with the left / right sides of the body to form a body frame assembly, which provides support for the roof of the body and meets the requirements of the rear door assembly. assembly. In order to improve the rigidity a...
