The invention relates to the technical field of automobile spare tire placement structures, in particular to an automobile spare tire support. The spare tire support comprises a top support, a vertical support, a telescopic air cylinder and a swing rod with a spare tire containing position, wherein the vertical support is composed of a first vertical long rod, a second vertical long rod and connecting pieces arranged between the two long rods, the lower end of the swing rod is hinged to the lower end of the first vertical long rod, a folding support is arranged between the lower section of theswing rod and the lower section of the first vertical long rod, the middle hinge point of the folding support is hinged to the outer end of a telescopic rod of a telescopic air cylinder, the tail endof a telescopic air cylinder body is hinged to a support, a fixed supporting rod base corresponding to the free end of the swing rod is arranged at the end of the top support, and the fixed supporting rod base is detachably connected and fixed with the free end of the swing rod. According to the spare tire support, the telescopic air cylinder is matched with the folding support, and the spare tire support has the advantages of being long in spare tire conveying distance, small in swing amplitude of the telescopic air cylinder, gentle in stress of hinged positions and long in service life of the hinged positions.
本发明涉及汽车用备胎安置结构技术领域,具体涉及一种汽车备胎支架。该备胎支架包括顶部支架、竖向支架、伸缩气缸和带备胎安置位的摆杆,竖向支架由第一竖向长杆、第二竖向长杆以及安置在两长杆之间的连接件组成,摆杆的下端与第一竖向长杆的下端部铰接,摆杆下段与第一竖向长杆的下段之间设置有折叠支架,折叠支架的中部铰接点与伸缩气缸的伸缩杆外端铰接,伸缩气缸本体的尾端铰接在支座上,顶部支架的端部设置有与摆杆的自由端相对应的固定支杆座,固定支杆座与摆杆自由端之间为可拆卸连接固定。该备胎支架采用伸缩气缸与折叠支架的配合,具有备胎输送距离长,伸缩气缸摆动幅度小、各铰接处受力平缓、各铰接处使用寿命长的优点。
