The invention discloses an integrated electric spare tire lifting device, which adopts a worm and gear transmission structure and integrates a spare tire lifting actuating mechanism on a worm gear rotating shaft. When the motor lifting button is started, the worm drives the worm gear to rotate, the steel wire rope rotates in the annular groove, and lifting of the spare tire is achieved through winding and unwinding of the steel wire rope. According to the technical scheme, through the innovative design of the worm gear structure, integration of the spare tire lifting executing mechanism and the worm gear is achieved. When the spare tire is lifted to a certain position and the lifting button is loosened, the worm transmission shaft loses driving force, and due to the fact that the worm gear and the worm can achieve the self-locking function, the spare tire cannot fall off and is maintained at the current position. By means of the structure, the purposes of speed reduction and torque increase of lifting of the spare tire are achieved, and meanwhile the spare tire is automatically locked after a power source is removed. And the outer shell and the spare tire ascending (descending) button have an integrated structural design characteristic. The invention further discloses a vehicle applying the integrated electric spare tire lifting device.

    本发明公开了一种集成式电动备胎升降装置,采用蜗轮蜗杆传动结构,并把备胎升降执行机构集成在蜗轮转动轴上。电机升降按钮启动时,蜗杆带动蜗轮转动,钢丝绳在环槽内转动,即通过钢丝绳的收放,实现备胎的升降。此技术方案通过蜗轮结构的创新设计,实现了备胎升降执行机构与蜗轮的集成化。当备胎升降至某一位置,松开升降按钮时,蜗杆传动轴失去驱动力,由于蜗轮蜗杆可实现自锁功能,备胎不会跌落并维持当前位置。此结构实现了备胎升降的减速增扭的目的,同时实现了撤销动力源后,备胎自动锁定位置。外壳体和备胎升(降)按钮具有集成式的结构设计特征。本发明还公开了一种应用上述集成式电动备胎升降装置的车辆。
