Automobile with one-time formed plastic shell

Abstract

The invention relates to an automobile with a one-time formed plastic shell. The automobile comprises an automobile body and a chassis, wherein the automobile body is a hollow double-layer plastic shell which is integrally formed at one time by a rotational molding process and is provided with an automobile door installation hole and an automobile window installation hole in advance; a plurality of contact reinforcing ribs are formed between an inner-layer wall body and an outer-layer wall body of the hollow double-layer plastic shell; a plurality of convex reinforcing ribs are formed on the external surface of the outer-layer wall body or the inner-layer wall body of the hollow double-layer plastic shell; a chassis embedding groove is formed at the lower end of the external surface of the inner-layer wall body of the hollow double-layer plastic shell; a plurality of threaded sleeves are embedded into the chassis embedding groove; the chassis is embedded into and in threaded connection with the chassis embedding groove; the external surface of the inner-layer wall body of the hollow double-layer plastic shell is provided with door post embedding grooves on two sides of the automobile door installation hole; and the upper end of the chassis is fixedly provided with door posts inserted into the door post embedding grooves. The automobile has the advantages of high strength and surface performance, light body weight, low cost and the like, and is easy to manufacture and convenient to assemble.

Description

Technical field: [0001] The invention relates to the field of automobiles (including electric automobiles, motor automobiles, and hybrid electric automobiles), in particular to automobiles with one-time molded plastic car shells. Background technique: [0002] Chinese invention patent ZL01142849.X discloses a new type of plastic body structure, which is composed of body parts connected by a skeleton and an outer shell. The hollow sandwich member is formed by merging the sheets. There is sufficient space in the hollow sandwich member to contain the inner bracket, and the space of the sandwich member is filled with foam plastic, and then the overall shell is fixed and formed to form a body part. The disadvantages of this structure are: 1. Although the aluminum alloy inner bracket and foaming in the sandwich member can ensure the strength, it also increases the cost and production process; Molding is troublesome, and after the aluminum alloy inner bracket is assembled, the inn...

AI Technical Summary

Problems solved by technology

The disadvantages of this structure are: 1. Although the aluminum alloy inner bracket and foaming in the sandwich member can ensure the strength, it also increases the cost and production process; Molding is troublesome, and after the aluminum alloy inner bracket is assembled, the inner and outer sheets need to be fixed together to form a sandwich member. The whole production process is very cumbersome; 3. The surface performance of the product is not good, and seams and wall thickness are prone to occur Uneven phenomenon; 4. The design of the whole vehicle is the same as that of traditional vehicles. The body parts are decomposed into top cover, base, front fender, rear fender, etc., which need to be assembled piece by piece during assembly, which is very inconvenient
