example 2:

as shown in fig. 1 and 2, the anti-collision device 4 is arc-shaped, the bottom end of the anti-collision device is connected with one end of the flight rod 2 far away from the machine body 1, a plurality of ball grooves are formed in the side surface of the anti-collision device 4 far away from the machine body 1, and rolling balls 7 are arranged in the ball grooves.

When can making buffer stop meet the object through the roll ball, become the rolling friction with the friction that the contact produced, the reduction friction that can be great leads to unmanned aerial vehicle's damage, the direction of stress when can changing unmanned aerial vehicle collision through rolling friction moreover to fall to minimum with unmanned aerial vehicle's harm.

Example 3:

as shown in fig. 1 and 5, a connecting groove 8 is formed in one end of the flight bar 2, which is far away from the machine body 1, one end of the connecting groove 8, which is far away from the interior of the anti-collision device 4, which is fixedly connected with a buffer spring 9, a through hole 10 is formed above the connecting groove 8, a limiting groove 11 is formed in the middle of the inner wall of the through hole 10, a connecting key 12 is arranged in the through hole 10, a limiting ring 13 is fixedly connected to the middle of the connecting key 12, and the limiting ring 13;

be provided with connecting block 14 in the spread groove 8, the one end and the buffer spring 9 contact of connecting block 14, the other end passes through powerful spring 15 and buffer 4's bottom to be connected, and limiting groove 16 has been seted up to connecting block 14's top, is provided with spacing post 17 in the limiting groove 16, and lifting spring and limiting groove 16 connection are passed through to spacing post 17's bottom.

When the collision-prevention device 4 of the unmanned aerial vehicle collides with an object, the collision-prevention device is extruded through the object and moves towards the inside of the connecting groove 8 through the connecting block 14, so that buffering is realized through the buffer spring 9, and the diameter of the through hole 10 is far larger than the diameter of the cross section of the limiting column 17, so that the limiting column 17 can move in the through hole 10 in the horizontal direction;

the anti-collision device 4 can be replaced at any time in a detachable mode, and the operation is that the limit column 17 is pressed downwards by pressing the connecting key 12, then the anti-collision device 4 can be pulled out, during installation, the limit column 17 is pressed manually until the limit column 17 is placed in the connecting groove 8, then the anti-collision device 4 is pushed until the limit column 17 is pushed into the through hole 10, force in all directions on the anti-collision device 4 can be converted into deformation of bending of the strong spring through the strong spring 15, and then the anti-collision device is automatically restored to the original shape;

this patent is through the good flight wing of protection that anti-collision device 4 can be fine, and then protects good whole unmanned aerial vehicle, can be fine when bumping convert the power that unmanned aerial vehicle received to the reduction collision that can be great is to the harm that unmanned aerial vehicle caused.

Example 4:

as shown in fig. 5, a sponge ring 18 is connected to the side of the flight bar 2 close to the impact prevention device 4.

When strong spring 15 takes place to warp through the bending, can play the effect of buffering through the sponge layer, under the condition that does not receive external force, the sponge layer can fill the space between flight bar and the buffer stop.
