The invention relates to the technical field of vehicle door collision prevention, in particular to an anti-collision supporting device for a bulletproof vehicle door, which comprises a door body, a supporting plate is movably mounted on the outer side of the door body, primary buffer mechanisms are arranged at four corners of the back side of the supporting plate, and secondary buffer mechanisms are arranged at the top and the bottom of the back side of the supporting plate. And a three-stage buffering mechanism is arranged at the center of the back of the supporting plate, the primary buffering mechanism comprises four first fixing sleeves fixedly connected to the inner wall of the door body, and first sliding rods are slidably installed in the four first fixing sleeves correspondingly. Triple buffering of the impact moment impulse of the vehicle door is achieved through the primary buffering mechanism, the secondary buffering mechanism and the tertiary buffering mechanism, meanwhile, the impacted side wall of the outer side of the vehicle door is stably supported through the auxiliary supporting mechanism, the anti-collision effect of the bulletproof vehicle door is greatly improved, impact deformation is effectively reduced, and the service life of the bulletproof vehicle door is prolonged. And the life safety of people polices is fully guaranteed.

    本发明涉及车门防撞技术领域,尤其涉及一种防弹车车门用防撞击支撑装置,包括门体,所述门体的外侧活动安装有支撑板,所述支撑板的背侧四个拐角处设有初级缓冲机构,所述支撑板的背侧顶部和底部均设有二级缓冲机构,所述支撑板的背部中心处设有三级缓冲机构,所述初级缓冲机构包括固定连接在门体内壁的四个第一固定套,四个第一固定套的内部均滑动安装有第一滑杆。本发明通过初级缓冲机构、二级缓冲机构、三级缓冲机构实现对车门受撞击瞬间冲量的三重缓冲,同时通过辅助支撑机构对车门外侧受撞击侧壁进行稳定支撑,大大提高了防弹车门的防撞效果,有效减少了受撞击形变,充分保障了人民警察的生命安全。
