The invention relates to a flip-up back door assembly of an automobile. The assembly comprises an outer plate and an inner plate as well as a back door glass window frame, wherein mutually symmetric hinge reinforcing plates are disposed on edges of the left upper part and the right upper part of the inner plate respectively; mutually symmetric stay bar reinforcing plates are disposed on edges of the left middle part and the right middle part of the inner plate respectively, the upper end of the stay bar reinforcing plate on the edge of the left middle part is firmly connected to the lower end of the hinge reinforcing plate on the edge of the left upper part, the fixed connection part is, and the upper end of the stay bar reinforcing plate on the edge of the right middle part is firmly connected to the lower end of the hinge reinforcing plate on the edge of the right upper part; a windshield wiper installation plate is disposed on the middle part of the inner plate, and the windshield wiper installation plate is corresponding to the lower middle part of the back door glass window frame; and a door lock installation plate is disposed on the lower middle part of the inner plate. The assembly provided by the invention has the advantages that overall back door rigidity and local rigidity of installation points can be increased; deformation does not take place easily; and vibration and abnormal sounds can be reduced.
Description
technical field [0001] The invention relates to a car body, in particular to a lift-up rear door assembly for a hatchback passenger car. Background technique [0002] The opening at the rear of the car body will be opened and closed by the back door. The structure of the back door has a side-opening type and a lift-up type, and the lift-up type is usually used. The side opening type is mainly used for relatively large SUV models or commercial vehicles. When the back door is in the closed state, in order to prevent problems such as vibration and noise of the back door caused by external excitation and excessive drop of the back door, it is required that the back door as a whole must have sufficient rigidity. In the traditional car back door structure, in order to improve the overall rigidity of the back door, the structural design of the inner panel of the back door or the lower part of the back door assembly is focused on, ignoring the influence of the shape of the back doo...
