The invention relates to the technical field of tire lifting, and provides an automobile tire lifting mechanism which comprises a power source, a gearbox and a base, the output end of the power source is provided with a driving gear, the gearbox is provided with a follow-up gear, the driving gear is meshed with the follow-up gear, and the driving gear is meshed with the follow-up gear. Connecting shafts are movably hinged to the two sides of the gearbox, and through arrangement of the first air cylinder, the second air cylinder and other structures, when tires of a vehicle need to be lifted to wade into water or get out of trouble, the first air cylinder and the second air cylinder are synchronously started. A first air cylinder enables a sliding shaft to slide to drive a connecting shaft to be separated from a straight shaft, a second air cylinder enables a moving shaft to slide, a fixing frame is separated from a mounting base, a base moves downwards, a tire mounting block is lifted away from a chassis, a vehicle is lifted through counter-acting force, and after the required height is reached, a power source retarding mode is started, and the tire mounting block rotates wheels through gear transmission; by means of the technical scheme, the problems that in the prior art, safety is insufficient, and stability is poor are solved.
本发明涉及轮胎升降技术领域,提出了一种汽车轮胎升降机构,包括动力源、变速箱以及底座,所述动力源的输出端安装有主动齿轮,所述变速箱上安装有随动齿轮,所述主动齿轮与所述随动齿轮相啮合,所述变速箱的两侧均活动铰接有连接轴,通过一气缸、第二气缸等结构的设置,车辆需轮胎抬起涉水或脱困时,同步启动第一气缸、第二气缸。第一气缸使滑动轴滑动,带动连接轴与直轴分离,第二气缸使移动轴滑动,固定框与安装座分离,底座下移,轮胎安装块抬离底盘,利用反作用力抬车,到达所需高度后,启动动力源缓速模式,通过齿轮传动使轮胎安装块转动车轮,提高车辆涉水和脱困安全性,通过上述技术方案,解决了现有技术中的安全性不足和稳定性差问题。
