Fender support made of composite materials

Abstract

The invention discloses a fender support made of composite materials. The fender support comprises a base, a pipe, a plug and a bolt, and is characterized in that sealants are coated at one end of the pipe, the end of the pipe is fixed into the base by the aid of the bolt, the plug is mounted at the other end of the pipe, the cut cross section of the pipe is elliptical or is in the shape of another polygon, the base is made of PA66 (polyamide 66)+GF30 (glass fiber 30) and SMC (sheet molding compound) resin or thermoset composite materials by means of injection molding or compression molding, and the pipe is made of unsaturated resin, phenolic resin, epoxy resin, PA66+GF30 or thermoset composite materials by means of injection molding or pultrusion or compression molding. The fender support with the arrangement has the advantages that the problem of easiness in corrosion and rusting of a fender support made of metal materials can be fundamentally solved; the fender support is high in strength and can be lightened, and the manufacturing cost of the fender support can be reduced; the fender support is excellent in toughness and vibration reducing performance, the problem of loosening of connection between a support rod and a fixing base can be solved by a base and pipe connection mode of the fender support, the pipe can effectively prevent a fender from rotating, and accordingly the fender support is stable.

Description

Technical field [0001] The invention relates to a composite fender bracket for installation on a car. Background technique [0002] The fender bracket is an important part of the connection between the fender and the tail light and the frame. At present, the fender bracket in the commercial vehicle field is mainly made of metal; its structure is a fixed base, a support rod welded structure or a fixed base and support Damping structure of rod vulcanized rubber. The metal fender brackets of these two structures have the defects that the paint film on the product surface is cracked, which is easy to rust and even be broken by corrosion. The fender bracket with the fixed base and the support rod directly welded to form a structure has poor shock absorption effect, which is easy to cause the phenomenon of loose and cracked connection between the fender and the support rod. Although the damping effect of the fender bracket with the rubber vulcanized damping structure between the fixe...

AI Technical Summary

Problems solved by technology

[0005] The invention fundamentally solves the problem that the metal fender bracket is easy to corrode and rust, and has high strength, which can reduce product weight and production cost. At the same time, its excellent toughness has good shock absorption performance. The connection method adopted solves the problem of loose connection between the support rod and the fixed base. The tube body can effectively prevent the rotation of the fender and is more stable
