Auto lined light plastic sheet

Abstract

The invention belongs to the technical field of plastic sheets, specifically to an auto lined light plastic sheet, comprising a plate, a cavity, rebounding modules and a buffering modules; a pluralityof the rebounding modules are arranged on the plate, and the cavity is formed on the inside of the plate, and the buffering modules are arranged between two adjacent rebounding modules on the insideof the cavity; the rebounding modules comprise a first elastic plate group, a second elastic plate group, a extrusion spring and a rebounding unit; one end of the first elastic plate group is fixedlyconnected with the inner wall, located above the cavity, of the plate; the second elastic plate group is fixedly connected with the other end of the first elastic plate group; the rebounding unit is arranged inside the second elastic plate group; the buffering modules comprise flat wire springs, a rectangular sleeve and a block, the buffering modules are composed of a plurality of flat wire springs splicing together with each other, and the flat wire springs at the two ends of the buffering modules are respectively connected with an adjacent first elastic plate group. The invention may improvethe buffering efficiency of the plate and extend the service life of the plate.

Description

technical field [0001] The invention belongs to the technical field of plastic sheets, in particular to a lightweight plastic sheet for automobile inner linings. Background technique [0002] In the prior art, the exterior parts of automobiles, such as front and rear panels, body panels, bumpers, masks, fenders, etc., are generally made of metal, thermosetting fiber-reinforced composite materials or thermoplastics. Thermosetting fiber-reinforced composite materials have a high density and cannot be recycled after molding. With the increasing number of automobiles, the environmental problems caused by them are becoming more and more serious. In order to adapt to the development trend of energy saving, environmental protection, and lightweight in the automotive industry, the development of lightweight, coating-free composite sheet structures for automotive exterior decoration has become a focus of attention in the automotive and related industries. Thermoplastic fiber-reinfor...

AI Technical Summary

Problems solved by technology

However, the use of lightweight materials reduces the protection efficiency of the car body, and the lightweight materials are easily worn and damaged by the impact of stones during use, which reduces the service life. Therefore, a lightweight plastic sheet for automobile inner lining is proposed, which can improve The cushioning effect of the plate prolongs the service life of the plate
