The invention discloses a multifunctional automobile back hanging type spare tire protection device which comprises an air guide pipe, a side wall is arranged in the middle of the air guide pipe to divide the air guide pipe into two areas, and one end of the air guide pipe is fixedly connected with a Z-shaped pipe in a communicating mode. Through the arrangement of an L-shaped pipe and an L-shaped rod, the device can be effectively and firmly fixed to the rear portion of a vehicle, and it is avoided that due to infirm fixing or insufficient supporting force, a back hanging type spare tire bumps in the driving process, the spare tire pulls a rear vehicle door and the vehicle door deforms; at the moment, the L-shaped pipe and a rear vehicle door hinge are located on the same vertical line, in this way, when the rear vehicle door is opened, a second box body rotates on the L-shaped pipe to open the rear vehicle door conveniently, when the vehicle is rear-ended in the running process after the spare tire is placed, a second spring and a first spring are arranged, the buffering effect can be effectively achieved, and then the situation that the tail door is sunken and deformed due to collision is effectively avoided; in addition, in the running process of the vehicle, a porous ceramic material is arranged, so that the tail gas can be effectively purified.

    本发明公开了一种多功能汽车背挂式备胎保护装置,包括导气管,导气管的中部设有侧壁将其分成两个区域,导气管的一端连通固定连接有Z型管。通过L型管和L型杆的设置,可有效的将该装置牢固的固定在车后方,避免背挂式备胎由于固定不牢靠或者支撑力不够,在驾驶中颠簸使得备胎就会拉扯后车门导致形变,而且此时L型管与后车门铰接合页在同一竖线上,这样在打开后车门时,第二箱体在L型管上旋转便于将后车门打开,当备胎放置好后行驶中车子被追尾的时候,通过第二弹簧和第一弹簧的设置,可有效的起到缓冲作用,进而有效的避免撞击导致尾门凹陷变形;而且在汽车行驶的过程中,通过多孔陶瓷材料的设置,可有效的对尾气起到净化的作用。
