The invention relates to the technical field of unmanned helicopters, and discloses a buffer device with an anti-collision function for an unmanned helicopter. The buffer device comprises a machine body, buffer boxes are fixedly mounted on the outer walls of the left and right sides of the machine body, a plurality of insertion cylinders are inserted into the outer walls of the buffer boxes, arc-shaped anti-collision plates are fixedly mounted at the tail ends of the insertion cylinders, first springs are further arranged on the outer walls of the inserting cylinders, and the first springs are fixedly connected between the buffer boxes and the arc-shaped anti-collision plates. When a machine body of the unmanned helicopter collides with an obstacle, elastic rubber on the arc-shaped anti-collision plates is firstly extruded, the elastic rubber is extruded to sink inwards, gas in an arc-shaped cavity is exhausted through an exhaust groove, and first-stage buffering protection can be carried out; and when the machine body of the unmanned helicopter collides with the obstacle, the whole arc-shaped anti-collision plates move towards the buffer boxes, the arc-shaped anti-collision plates move towards the buffer boxes to compress the first springs on the insertion cylinders, and the first springs are stressed and compressed, so that secondary buffer protection can be carried out.

    本发明涉及无人直升机技术领域,且公开了一种无人直升机用具有防撞功能的缓冲装置,包括机体,所述机体的左右两侧外壁均固定安装有缓冲盒,所述缓冲盒的外壁插设有若干个插筒,若干个所述插筒的末端固定安装有弧形防撞板,若干个所述插筒的外壁还设置有第一弹簧,所述第一弹簧固定连接在缓冲盒与弧形防撞板之间。无人直升机的机体撞到障碍物时,首先会挤压弧形防撞板上的弹性橡胶,弹性橡胶被挤压向内凹陷,弧形腔内的气体通过排气槽排出,便能够进行一级缓冲保护;无人直升机的机体撞到障碍物时还使弧形防撞板整体向缓冲盒处移动,弧形防撞板向缓冲盒处移动会压缩插筒上的第一弹簧,第一弹簧受力压缩便能够进行二级缓冲保护。
