Abstract

The invention provides a reinforcing member for a vehicle backdoor inner plate. The vehicle backdoor inner plate comprises a windshield installing hole formed in the upper portion of the vehicle backdoor inner plate and D-column areas located on the two sides of the windshield installing hole; the reinforcing member comprises a pair of reinforcing member bodies symmetrically arranged in the D-column areas, wherein each reinforcing member body is divided into a bent section and a vertical section from top to bottom, both the bent section and the vertical section are composed of first side walls, second side walls and first bottom plates, a honeycomb structure is arranged between the first side wall and the second side wall, and the reinforcing member is wholly formed by a composite material. The honeycomb-type composite-material reinforcing member is high in strength, light in weight, simple in forming technology and high in size accuracy and stability and is used for the vehicle backdoor inner plate.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, and more particularly relates to a reinforcement for the inner panel of a vehicle back door. Background technique [0002] The main body of the back door of a hatchback or SUV is usually formed by sheet metal stamping, which has the disadvantages of heavy weight and limited shape. As the requirements for energy saving and emission reduction become more and more stringent, the advantages of plastic back doors, such as high integration, obvious weight reduction effect and high degree of freedom in shape, are getting more and more attention. However, the modulus of the plastic back door is much lower than that of the sheet metal back door. Therefore, in this field, the inner panel of the plastic back door combined with metal inserts or metal assemblies is usually used to meet the rigidity of the overall back door, especially the D-pillar area. , strength and other performance requirements. ...
