The invention discloses a rear door window frame reinforcement structure and a vehicle rear door, which belong to the technical field of automobiles. The rear door window frame reinforcement structure includes a rear door window frame rear reinforcement plate, a rear door upper hinge mounting plate, a rear door lock reinforcement plate and a rear door inner panel front reinforcement plate, and the rear door window frame is welded at the four corners of the rear door window frame respectively for reinforcement plate, the upper hinge mounting plate of the rear door, the rear door lock reinforcement plate and the front reinforcement plate of the rear door inner panel. The invention improves the installation strength of the installation point of the lifting car door and the rigidity of the car door, simplifies the number of parts of the rear door assembly, simplifies the welding process, and reduces the cost of processing and forming the car door.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a rear door window frame reinforcement structure and a car rear door. Background technique [0002] The rear sliding door of the existing model design adopts the local welding reinforcement of the inner plate, and then realizes the rear door assembly through the fastening of the inner and outer plates. In the rear door assembly of this structure, the rear door window frame has the following defects: 1. The rear door window frame needs to be designed with multiple reinforcements and glass runners, the mold cost is high and the parts are difficult to form; 2. The rear door window frame is partially reinforced, It will cause the rigidity and strength of the rear door window frame to be weak, and the door will tremble when closed. Contents of the invention [0003] In order to solve the problems of the prior art, the embodiment of the present invention provides a rear door win...
