Abstract

The invention discloses an inner panel of a resin back door. The inner panel of the resin back door is an integral structure, including an annular rear window and an annular reinforcing unit located below the annular rear window. The annular reinforcing unit includes an upper Side reinforcing beam, left lower reinforcing beam and right lower reinforcing beam, there is a left tail light mounting hole between the left end of the upper side reinforcing beam and the outer end of the left lower reinforcing beam, the right end of the upper side reinforcing beam and the A right taillight installation hole is left between the outer ends of the lower right reinforcement beam, a door lock installation hole is left between the inner end of the left lower reinforcement beam and the inner end of the right lower reinforcement beam, and the upper side reinforcement beam, The left lower reinforcing beam and the right lower reinforcing beam form an annular reinforcing structure. In one embodiment of the present invention, the annular reinforcing unit under the annular rear window can increase the rigidity and strength of the inner panel of the resin back door without significantly increasing the weight of the inner panel of the resin back door, satisfying lightweight requirements.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a resin back door inner panel. Background technique [0002] Lightweight is the key direction of the development of the automobile industry. The resin back door is a key case of lightweight car body. Its weight reduction effect can reach 30%, exceeding 7kg. At the same time, it also greatly increases the freedom of shape, function and assembly integration. Spend. [0003] Almost all new energy vehicles use resin back doors, but the existing resin back doors are not rigid and strong enough to reach the level of sheet metal, especially torsional rigidity. If the inner plate thickness or complex structure is increased, the lightweight effect will be greatly reduced. [0004] Therefore, it is necessary to design a resin back door inner panel that can simultaneously meet the requirements of rigidity, strength and light weight. Contents of the invention [0005] The object of ...
