the tail gate reinforcement 2 is connected with the hinge reinforcement plate 1 and the lock reinforcement plate 3 and is fixedly connected with the tail gate inner plate 4 to form an integrated series structure.
More specifically, in the present embodiment:
as shown in fig. 1, the tail gate reinforcement 2 connects the hinge reinforcement plate 1 (for reinforcing the local strength of the installation area of the hinge 8) and the lock reinforcement plate 3 (for reinforcing the local strength of the installation area of the lock), and at the same time, the tail gate reinforcement 2 is fixedly connected with the tail gate inner plate 4, so that the tail gate inner plate 4, the hinge reinforcement plate 1 and the lock reinforcement plate 3 form a series structure, and the tail gate has a continuous stress path, thereby improving the overall strength of the tail gate. To the condition that still is provided with the bulb mounting point on the tail-gate, can be through increasing the pole bulb reinforcing plate is connected to one section tail-gate reinforcement 2, strengthen bulb department structure.
The tail gate reinforcement 2, as shown in fig. 2, is formed by bending a standard section profile, and the material of the tail gate reinforcement 2 includes but is not limited to metal or plastic, and the main purpose is to provide strength and fixation and series connection of each area metal piece (reinforcing plate) and the tail gate inner plate 4; fig. 2 shows a conventionally used square section tail gate reinforcement 2 (fig. 2 (a), 2 (b)) and a round section tail gate reinforcement 2 (fig. 2 (c), 2 (d)), the square section tail gate reinforcement 2 can be directly matched with a mounting surface at a connection part due to its own shape, and a process path is mainly bending and punching; the tail gate reinforcement 2 with the circular cross section needs to be flattened at the joint part to be oblate, so that the tail gate reinforcement is matched with the mounting surface. Overall, the tailgate reinforcement 2 is simpler and less costly than conventional sheet metal forming processes.
Fig. 3 (a) and 3 (b) show schematic assembly structures of the square-section tailgate reinforcement 2 and the circular-section tailgate reinforcement 2 at the connection (exemplified by the hinge 8 mounting plate), respectively. It can be seen that the hinge 8, the inner door panel 4, the mounting plate for the hinge 8 and the reinforcing member 2 are fastened and fixed by screw-fitting between nuts previously fixed to the reinforcing member 2 and bolts 7 sequentially passing through the respective layers.
