External-hanging type spare tire rapid replacement device and spare tire mounting and detaching method

Abstract

The invention discloses an external-hanging type spare tire rapid replacement device and a spare tire mounting and detaching method. The defects that an existing spare tire rapid replacement device is hard in spare tire mounting and detaching processes, the difficulty of spare tire replacement is increased, spare tire mounting and detaching operation is complex, the stability of a spare tire is not good after mounted on the rapid replacement device, and the safety hidden danger of slipping exists are overcome. The external-hanging type spare tire rapid replacement device comprises a base, a spare tire storage frame and a mounting frame; a left clamping arm and a right clamping arm are arranged on the mounting frame; the spare tire storage frame is connected on the left clamping frame and the right clamping frame in an abutting mode; a spring balancer is mounted on the left clamping arm; a coil spring is arranged in the spring balancer; one end of the coil spring extends out of the balancer and is connected with and tightens the spare tire storage frame; a connecting lock is mounted between the right clamping arm and the spare tire storage frame; a spare tire positioning mechanism is connected on the inner surface of the spare tire storage frame; the spare tire is mounted on the spare tire storage frame and positioned through the spare tire positioning mechanism; and an elastic positioning pin used for being connected on the inner wall of a spare tire rim in an abutting mode is arranged at the upper end of the mounting frame.

Description

technical field [0001] The invention relates to a spare tire installation device, more specifically, it relates to a labor-saving external spare tire quick change device and a spare tire loading and unloading method. Background technique [0002] Generally, a spare tire is equipped on a car, and its specification is the same as that of the original car tire, so that it can be replaced in time when the car tire blows out. Depending on the model, the spare tire is generally placed under the trunk floor or hung under the rear of the car or fixed outside the trunk door. Different storage positions have different spare tire storage racks. Usually, the spare tire is installed on the spare tire storage rack. When the spare tire needs to be replaced, the spare tire is removed from the spare tire storage rack. For the automobile that spare tire is placed outside the trunk door, an external spare tire quick-changing device is connected outside the automobile trunk door, and the spare...

AI Technical Summary

Problems solved by technology

[0004] The invention overcomes the laboriousness of the existing spare tire quick change device in the process of loading and unloading the spare tire, which increases the difficulty of spare tire replacement, the operation of spare tire loading and unloading is cumbersome, and the stability of the spare tire after being installed on the quick change device is not good. There is a safety hazard of slipping, and an externally mounted spare tire quick change device and a spare tire loading and unloading method are provided. The spare tire loading and unloading process is relatively labor-saving, which greatly reduces the difficulty of spare tire replacement. After being installed on the quick change device, the stability is good, which avoids the safety hazard of the spare tire slipping off
