Problems solved by technology

This method has extremely high requirements on the verticality of the shaft and the pump handle, and it is difficult to guarantee the accuracy of production and processing. It often requires a lot of manual corrections, inter-matching inspections, etc., which not only causes waste of resources, but also may eventually lead to failure of the product to be installed. Or installation is difficult, causing the product to be scrapped
On the other hand, although the casing can be adjusted at a certain angle, thereby realizing the height adjustment of the spare tire rack, but because the rotating shaft is cylindrical, the casing is damaged by force during adjustment, resulting in structural failure

Abstract

The invention relates to the technical field of automobiles, and discloses an automobile rear bumper and an automobile. The automobile rear bumper comprises a bumper body installed at the tail of theautomobile, a spare wheel carrier, a shaft sleeve and a circular-truncated-cone-shaped rotating shaft; the rotating shaft is arranged at one end of the bumper body in a swinging mode, and the shaft sleeve is fixed at one end of the spare wheel carrier; the spare wheel carrier is arranged on the rotating shaft in a rotating and sleeving mode; and the other end of the spare wheel carrier is detachably connected with the bumper body. According to the automobile rear bumper and the automobile, the circular-truncated-cone-shaped rotating shaft is arranged, and the rotating shaft is arranged at oneend of the bumper body in a swinging mode; meanwhile, the shaft sleeve is arranged at one end of the spare wheel carrier, and the rotating shaft is sleeved with the shaft sleeve so that the lower endof the shaft sleeve can swing left and right around the upper end of the spare wheel carrier when the other end of the spare wheel carrier ascends or descends; free adjustment of the angle of the spare wheel carrier is achieved, damage to the shaft sleeve due to stress during adjustment is avoided, and structural reliability is guaranteed; and vertical precision is not required, production requirements are reduced, and popularization and application are easy.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile rear protection bar and an automobile. Background technique [0002] At present, some models can be equipped with spare tires on their vehicle bodies due to needs, and the installation methods of spare tires are various. One end welding sleeve pipe 300, then sleeve pipe 300 is socketed on the cylindrical rotating shaft 200 and realizes the rotation of spare tire carrier 2 (as Figure 6 ). This method has extremely high requirements on the verticality of the shaft and the pump handle, and it is difficult to guarantee the accuracy of production and processing. It often requires a lot of manual corrections, inter-matching inspections, etc., which not only causes waste of resources, but also may eventually lead to failure of the product to be installed. Or installation is difficult, causing the product to be scrapped. On the other hand, although the sleeve can be ...
