Car frame structure made of carbon fiber composite materials

Abstract

The invention discloses a car frame structure made of carbon fiber composite materials. The car frame structure comprises a front windscreen shield, a car rear tail cover, a left side enclosing plate, a right side enclosing plate, a car body chassis and a top cover, wherein the front windscreen shield, the car rear tail cover, the left side enclosing plate, the right side enclosing plate, the car body chassis and the top cover are integrally formed from carbon fiber composite materials and form the car frame structure through connecting structures. The car frame structure made of carbon fiber composite materials is simple in structure, light in weight, better in rigid intensity, and convenient for standardized production.

Description

technical field [0001] The invention relates to a vehicle frame structure, in particular to a carbon fiber composite material vehicle frame structure. Background technique [0002] In the prior art, the frame structure of city bus generally adopts steel structure, such as figure 1 As shown, the frame part of the entire steel structure is a closed welded structure, which is welded by multiple components, with a load-bearing overall metal skeleton inside, and the outer shell is formed by a sheet metal stamping die, and then fitted one by one on the on a metal frame. Yet the defective of described vehicle frame structure is: [0003] 1. The frame of the steel structure has a heavy body weight and is not easy to be modularized. [0004] Second, the frame of the steel structure is usually designed as a skeleton type, and the single component is large in size, which makes the welding operation complicated. Metal welding technology is required, which makes the weight of the prod...

Problems solved by technology

Yet the defective of described vehicle frame structure is:

[0003] 1. The frame of steel structure has a heavy body weight and is not easy to be modularized

[0004] Second, the frame of the steel structure is usually designed as a skeleton type, and the single component is large in size, which makes the welding operation complicated. Metal welding technology is required, which makes the weight of the product difficult to control, and local deformation is easy to produce. The production process is cumbersome and the production cycle is long. , and requires a larger production site

[0005] Three, the frame of the steel structure has a large skeleton, which makes the mold more complicated. At the same time, the forming process of the sheet metal body shell is cumbersome, and many molds are used

[0006] 4. The frame of the steel structure has many skeleton interfaces. During the welding process, it is easy to cause local deformation, which makes it difficult to assemble the skeleton part and the sheet metal shell part.

[0007] Fifth, there are many frame members of the steel structure, and they are assembled by welding, so that the rigidity of the entire frame structure is insufficient, the energy absorption and buffering capacity of the body is poor, and the impact strength and yield strength are low
