Once-formed plastic housing automobile

Abstract

The invention discloses an automobile with a one-time molded plastic body shell, including a vehicle body and a chassis. The vehicle body is a hollow double-layer plastic shell that is integrally formed by a rotational molding process and is preset with vehicle door installation holes and vehicle window installation holes. A plurality of kiss ribs are formed between the inner wall and the outer wall of the hollow double-layer plastic shell, and the outer wall of the hollow double-layer plastic shell or the outer surface of the inner wall is formed with Several convex reinforcing ribs, the lower end of the outer surface of the inner wall of the hollow double-layer plastic shell is formed with a chassis embedded groove, and a number of screw sleeves are pre-embedded in the chassis embedded groove, and the chassis is embedded in the chassis embedded groove. The groove is screwed with it, the outer surface of the inner wall of the hollow double-layer plastic shell is formed with door post insertion grooves on both sides of the door mounting hole, and the upper end of the chassis is fixed with a door post insertion groove. doorpost. The invention has the advantages of good strength, good surface performance, light vehicle body, simple manufacture, low cost, convenient assembly and the like.

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] There is a new type of plastic body structure, which is composed of the connection of body parts formed by the combination of the skeleton and the outer shell. Sandwich components, leaving sufficient space in the hollow sandwich components, containing the inner bracket, filling the space of the sandwich components with foam plastics, and then fixing and molding the overall shell to form body parts. 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 toget...

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. It is inconvenient to assemble them piece by piece
