Embodiment 1：
When colliding to solve to exist in the prior art rigidly connected safeguard structure, entire rotor arm can be caused all
Stress, thus be easy to cause unmanned plane fall damage the technical issues of, the present embodiment provides a kind of anticollision unmanned plane, such as scheme
1, shown in Fig. 2, including rotor platform 1,1 edge of rotor platform are evenly distributed with rotor arm 2, and 2 end of rotor arm is provided with rotor
3, rotor 3 is driven by flight motor 4 to be rotated, wherein each 2 end of rotor arm is both provided with anticollision mechanism；Anticollision mechanism includes
It is fixed on the linking arm 5 of rotor arm end, 5 end of linking arm is inserted into a dampening assembly 9, and 9 top surface of dampening assembly is provided with anti-
Plate 6 is hit, Crashworthy plate 6 is arc-shaped structure, and the center of circle is overlapped with the rotation center of rotor.
Dampening assembly 9 is provided with one for for connecting rod on shell 12 as shown in figure 3, including a shell 12 on one side
The through-hole 11 of insertion, connecting rod be inserted into shell 12 inside the opposite side in one end two on be symmetrically arranged with pulley 13；Shell
It is symmetrical arranged in 12 there are two buffer stopper 10, two opposite sides of buffer stopper 10 are disposed as inclined-plane, and pulley 13 connects with inclined-plane
It touches and is slided along inclined-plane；10 upper and lower ends of buffer stopper are slidably connected with 12 inner top wall of shell, bottom wall respectively；Two buffer stoppers
It is both provided with the first spring 7 between 10 and 12 internal side wall of shell, is provided between 12 bottom walls in 5 bottom end of linking arm and shell
Two springs 8.
Above-mentioned unmanned plane protects rotor 3 in flight course, by Crashworthy plate 6, ensures that rotor 3 will not touch extraneous obstacle
Then Crashworthy plate 6 is fixed on the periphery of rotor 3 by object by above structure, when colliding, connecting rod is to transporting inside shell 12
It is dynamic, inclined-plane sliding of the pulley 13 on buffer stopper 10, since the distance between two pulleys 13 are constant, but between two inclined-planes
Distance be variation, so in 13 sliding process of pulley and two buffer stoppers 10 is pushed to be moved to both sides, at this point, the
It under one spring 7 and the effect of the elastic force of second spring 8, can stop that linking arm 5 moves, that is, offset the active force that collision generates, from
