Automobile tail door

Abstract

The invention provides an automobile tail door. The automobile tail door comprises a tail door inner plate, and continuous fiber composite material structure connected with the tail door inner plate, wherein the continuous fiber composite material structure is formed by a continuous fiber composite material composed of continuous fibers and resin, the continuous fiber composite material structure is distributed in a key performance area on the tail door inner plate, and the key performance area comprises a hinge connecting part, a supporting rod ball head part, a door lock part and a wiper motor connecting part. On the basis of the continuous fiber composite material, the automobile tail door is preformed through mold pressing or other processes and then connected with the tail door inner plate through integral injection molding or post-assembly and other means, the weight of the door body is reduced, meanwhile, the rigidity and strength of the tail door can be guaranteed, and the integrity is enhanced.

Description

technical field [0001] The invention relates to the field of automobile tailgates, in particular to an automobile tailgate. Background technique [0002] At present, in the manufacture of automobile tailgates, in order to strengthen the rigidity of the important stress-bearing parts of the tailgate and improve the overall mechanical performance of the tailgate, two forms of metal inserts or metal assemblies are generally used. [0003] Among them, the disadvantages of metal inserts are: ① Stamping and forming, the structural design limitations are large; ② Thin material, weak structure, resulting in poor dimensional accuracy; ③ The metal is not compatible with the tailgate inner panel material, and the connection strength is weak. The disadvantages of metal assemblies are: ① Stamping and forming, the structural design limitations are large; ② The cost of metal bonding glue is relatively high. [0004] The above metal inserts and metal assemblies are all in the form of metal...
