The invention discloses an anti-overturning limiting structure for a crumple support of a steering column, which comprises a steering column and a limiting plate, wherein the steering column is sleeved with a fixing pipe, and a mounting support is clamped on the steering column. According to the invention, a mounting hole is formed in a pull-off block, a second threaded hole is formed in the mounting support, the steering column is inserted into the fixing pipe, the mounting support is clamped on the steering column, the two groups of first threaded holes are in threaded connection through bolts, the pull-off block is clamped on the mounting support, the two groups of injection molding pin holes are injection-molded together through injection molding pins; and the limiting supporting basecan provide support for the rear end of the mounting support in the crumple process of the steering column, provide torque opposite to the rotating direction of the mounting support, prevent the mounting support from turning over, avoid abnormal friction force between the pull-off block and the mounting support, and further avoid the problem that the crumple force at the position of the pull-off block is abnormally increased.
本发明公开了一种转向管柱溃缩支架防翻转限位结构,包括转向管柱和限位板,所述转向管柱上套设有固定管,所述转向管柱上卡设有安装支架,本发明拉脱块上开设有安装孔,安装支架上开设有第二螺纹孔,把转向管柱插入到固定管内,安装支架卡设在转向管柱上,通过螺栓把两组第一螺纹孔螺纹连接在一起,拉脱块卡设在安装支架上,通过注塑销把两组注塑销孔注塑在一起,限位支撑座可在转向管柱溃缩过程中给予安装支架后端支撑,提供与安装支架转动方向相反的一个扭矩,防止安装支架翻转,可避免拉脱块与安装支架之间的异常摩擦力产生,进而避免拉脱块位置处的溃缩力异常变大的问题。
