The invention discloses an automobile spare tire mounting bracket which comprises an external spare tire bracket, a bracket chassis connecting seat, a limiting metal chain, a spare tire passive air leakage device and a license plate, the external spare tire bracket is mounted on the bracket chassis connecting seat, and the bracket chassis connecting seat is fixedly mounted on an automobile tail chassis structure; the support chassis connecting base is connected with the external spare tire support through the limiting metal chain, and the spare tire passive air leakage device and the license plate are fixedly installed on the external spare tire support. The externally-hung spare tire support combines the advantages of hard connection and flexible connection, when the hard connection is broken, the metal chain of the flexible connection limits the movement of the broken part, and the safety is improved. Meanwhile, the vertical rotating design is adopted, a trunk is convenient to open or a spare tire is convenient to disassemble, and the risk of opening a door to kill is avoided. The passive air leakage device for the spare tire can quickly release air during high-speed rear-end collision, the spare tire is prevented from rolling or bouncing, the risk of traffic accidents is reduced, the spare tire after air leakage has buffering performance, and follow-up impact force is relieved.

    本发明公开了一种汽车备胎安装支架,包括外挂备胎支架、支架底盘衔接座、限制金属链、备胎被动泄气器和车牌,外挂备胎支架安装在所述支架底盘衔接座上,支架底盘衔接座固定安装在车尾底盘结构上;支架底盘衔接座并通过所述限制金属链与所述外挂备胎支架相连,外挂备胎支架上固定安装有所述备胎被动泄气器和车牌。本发明外挂备胎支架结合硬连接与软连接的优点,当硬连接断裂时,软连接的金属链限制断裂部分移动,提升安全性。同时,采用垂直旋转设计,便于开启后备箱或拆卸备胎,避免“开门杀”风险。备胎被动泄气器能在高速追尾时迅速泄气,防止备胎滚动或弹跳,减少交通事故风险,泄气后的备胎还具备缓冲性,减轻后续冲击力。
