Therefore, it is necessary to provide a new limit structure. Utility Model Content
[0003] The purpose of the utility model is to provide a new integrated limiting structure for the upper and lower bodies of the bumper. The structure adopts a pin + screw integration method. Under normal circumstances, the pin is adopted. The pin method can ensure the Y-direction matching surface difference of the upper and lower bodies of the bumper, and at the same time it can also save the cost of screws. The labor cost and working hours of screwing on the assembly line are greatly saved; the reservation of the screw structure can be used as a backup plan, and the integration of the two structures can take into account all assembly risks at the same time.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A novel integrated limiting structure for the upper and lower bodies of a bumper, wherein the limiting structure is provided with a mounting groove at the end of the upper body of the bumper, adjacent to the lower body of the bumper, and a mounting block for being assembled in the mounting groove is provided at the upper end of the lower body of the bumper, wherein the mounting groove and the mounting block are respectively arranged on both sides of the upper body of the bumper and the lower body of the bumper, and a latch hole is processed on the outer wall of the mounting groove, and a through hole is provided on the top surface of the mounting groove; the mounting block is provided with a latch at a position opposite to the latch hole, and a through block passing through the through hole is provided at a position opposite to the through hole, the upper body of the bumper and the lower body of the bumper are fixed by the latch and the through block, and the matching surface difference of the upper and lower bodies of the bumper is ensured; a screw hole penetrating the through block is provided at the center of the mounting block, and the screw hole is used to assemble screws when the latch fails, and the upper body of the bumper and the lower body of the bumper are fixed by the screws, and the matching surface difference of the upper and lower bodies of the bumper is ensured.
[0006] As a preferred embodiment of the present invention, the latch hole and the latch are both square structures.
[0007] The utility model has the following advantages and positive effects: the new integrated limiting structure provided by the utility model adopts a latch + screw integration method. Under normal circumstances, a latch is used. The latch method can ensure the Y-direction matching surface difference of the upper and lower bodies of the bumper, while also saving the cost of screws. The labor cost and working hours of screwing on the assembly line are greatly saved; the reservation of the screw structure can be used as a backup plan, and the integration of the two structures can take into account all assembly risks at the same time.
