The invention discloses a structure for preventing a vehicle door from slipping during side collision, which comprises an anti-slip column, the anti-slip column comprises a base, a rod handle and an anti-slip double ball, the base is fixed at the side lower corner of a rear vehicle door through a bolt, the rod handle is arranged above the base, and the anti-slip double ball is arranged above the rod handle; the anti-skid groove is formed in the side wall, the anti-skid groove is opposite to the anti-skid column in position, the anti-skid groove comprises a double-layer baffle and a mounting hole, the anti-skid groove is fixedly connected with the extrusion aluminum alloy doorsill, and the double-layer baffle and the anti-skid double balls are in multi-stage matched connection; in a normal state, the anti-skid grooves are in clearance fit with the anti-skid columns, and normal opening and use of the vehicle door are guaranteed; in the collision state, when the rear vehicle door turns on one side, the anti-skid double balls on the anti-skid columns make contact with the anti-skid grooves to apply force, and pulling-off is prevented through multiple times of mutual interference. The anti-slip structure can structurally ensure that the automobile door is firmly fixed on the side wall when the automobile door changes and turns over when the side collision happens to the automobile, a complete closed structure is formed for a passenger compartment, the side collision invasion amount of a barrier is reduced, and therefore the injury to passengers is reduced.

    本发明公开了一种满足侧碰防车门滑脱的结构,包括防滑柱,其包括底座、杆柄以及防滑双球,底座通过螺栓固定在后车门的侧下角,杆柄设置于底座上方,杆柄上方设置有防滑双球;防滑槽,设置于侧围上,防滑槽与防滑柱位置相对,防滑槽包括双层挡板和安装孔,防滑槽与挤压铝合金门槛固定连接,双层挡板与防滑双球形成多级匹配连接;在正常状态下,防滑槽与防滑柱间隙配合,保证车门正常开启使用;在碰撞状态下,后车门侧翻时,防滑柱上的防滑双球与防滑槽接触施力,通过多次相互干涉防止拉脱。本申请的防滑脱结构能够结构确保汽车发生侧碰车门发生变动翻转时把车门牢固的固定在侧围上,对乘员舱形成完整的封闭结构,降低壁障的侧碰侵入量,从而降低乘员伤害。
