The invention discloses a door collision prevention device. The door collision prevention device comprises a mounting box mounted at the lower end of a door, a telescopic mechanism mounted in the mounting box, and a controller mounted in the mounting box; a detector for detecting the moving speed is mounted on the mounting box; the lower end of the telescopic mechanism extends below the mounting box, and is connected with a brake part; the detector and the telescopic mechanism are electrically connected with the controller; and when the detector detects that the moving speed of the mounting box is higher than or equal to a set value, or the acceleration of the mounting box is higher than or equal to a set value, the controller controls the telescopic mechanism to downwards extend, so that the brake part is contacted with the ground for braking. When the door quickly rotates, the brake part decelerates the door or even stops rotation of the door, so that the door can be prevented from violently colliding with a door frame or a door stopper or a wall.
本发明公开了一种预防门撞器，包括有安装在门下端的安装箱，安装在安装箱内的伸缩机构，以及安装在安装箱内的控制器，所述安装箱上安装有检测移动速度的检测仪，所述伸缩机构下端延伸到安装箱下方，且伸缩机构下端连接有刹车部，所述检测仪和伸缩机构分别与控制器电性连接；当检测仪检测到安装箱移动速度大于或等于设定值，或安装箱的加速度大于或等于设定值时，控制器控制伸缩机构向下伸长，使得刹车部与地面接触进行刹车。当门快速转动时，刹车部对门进行减速甚至使门停止转动，这样就可以避免门与门框或门吸或墙壁发生剧烈碰撞。
