[0002] An automobile bumper is a safety device that absorbs and mitigates external impact forces and protects the front and rear parts of the vehicle body. A skeleton is installed inside the bumper, which plays an important role in protecting the components inside the vehicle head.

[0003] The utility model with the patent number 202021142560.8 provides an installation combination bracket for an automobile bumper. The installation combination bracket for an automobile bumper of this utility model mainly utilizes a bracket plate, and a groove is opened inside the bracket plate for filling with buckyballs. The buckyballs are neatly arranged in the groove by the magnetism of the buckyballs. A rubber outer sleeve is adopted outside the buckyballs. When a vehicle collides, the bumper is recessed inward to squeeze the rubber outer sleeve, and the impact force received by the bumper is buffered through the rubber outer sleeve, so as to achieve the shock absorption and buffering of the vehicle's frontal collision. However, in the prior art, the installation of automobile bumpers requires personnel to tighten multiple screw and bolt components, which is cumbersome and inefficient, and the protection strength is poor, and it is difficult to provide good buffering, resulting in poor protection for the vehicle and the passengers inside.

When the installation rod 8 is inserted into the mounting hole 3, the threaded rod 4 is rotated to make the two moving rods 5 move relatively, and the moving plates 14 at both ends are driven to move relatively by the diagonal brace 15, so that the positioning rod 6 on the moving plate 14 is inserted into the positioning hole 16, which can ensure the stability of the installation rod 8 in the mounting hole 3 and make the installation operation more convenient.

[0026] Embodiment 2

[0027] As Figures 1 to 4 shown in the figure, for an automobile bumper mounting structure, a threaded section is provided at the left end of the connecting rod 10, and a connecting nut is connected to the threaded section through the connecting hole 11.
