Drones are becoming more and more popular, and more and more people are playing with them. However, due to the large number of variables in high-altitude flight, drone crashes are relatively common. Unmanned aircraft are referred to as "drones", and the English abbreviation is "UAV". They are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or are completely or intermittently operated autonomously by on-board computers. Drones often perform tasks such as filming during flight. During the flight of drones, drones often collide and collide due to careless operation by operators or due to terrain and airflow, causing a certain degree of damage to the drone body.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The embodiment of the utility model provides a technical solution: a UAV flight anti-collision device, comprising a UAV 1, on the outer wall of which are mounted four connecting rods 2 which are equidistantly distributed in a ring shape, and at the ends of which are mounted power mechanisms 3, a base 6 is fixed to the bottom of the UAV 1; the cross section of the base 6 is an isosceles trapezoidal structure and a groove 4 is provided inwardly in the middle of the bottom surface, the groove 4 is a trapezoidal groove 4 and a buffer frame 5 is installed inside the groove 4, a plurality of buffer pads 7 are installed on both sides of the bottom surface of the base 6, and the heights of the plurality of buffer pads 7 decrease from both sides to the middle, and when landing, the buffer pads 7 from both sides to the middle contact with the ground or the platform in turn, so as to achieve a multi-stage buffering and shock absorption effect, play a better protection effect, and reduce the impact of the landing shock on the UAV 1.

[0023] In a further improvement, the power mechanism 3 includes a fixed box 13, a telescopic buffer tube 11 and an anti-collision plate 10. The fixed box 13 is installed at the end of the connecting rod 2 and a motor 9 is installed inside the fixed box 13. The rotor 8 is fixed to the power output end of the motor 9. The telescopic buffer tube 11 is vertically connected to the outer wall of the fixed box 13. The end of the telescopic buffer tube 11 is connected to the middle of the side wall of the anti-collision plate 10. The two ends of the telescopic buffer tube 11 are tubular and the middle part is rod-shaped. The two ends of the middle rod extend into the tube and are installed with elastic mechanisms to achieve a buffering effect. The anti-collision plate 10 has an arc-shaped structure and ventilation grooves 12 are evenly opened on both sides of the surface. A buffer strip is formed between adjacent ventilation grooves 12. The arc-shaped anti-collision plate 10 has a better protective effect on the rotor 8.

[0024] Further improved, the buffer frame 5 includes a fixed plate 16 and a buffer bent rod 15, the buffer bent rod 15 is an inverted J-shaped structure and is symmetrically installed at the bottom of the fixed plate 16, and a support pad 14 is installed at the bottom end of the buffer bent rod 15. The support pad 14 is released from the ground or platform and transfers the pressure to the end of the buffer bent rod 15.

[0025] As a further improvement, a buffer rod 17 is installed on the top of the buffer foot pad 7, the upper end of the buffer rod 17 extends to the inside of the base 6 and is movably connected to the base 6, a limit plate is installed on the upper end of the buffer rod 17, and a spring 18 is sleeved on the buffer rod 17, which plays a buffering and rebounding role.

[0026] Working principle: When the UAV 1 is flying, the anti-collision plate 10 on the power mechanism 3 can prevent the power mechanism 3 from directly colliding with other objects. When the UAV 1 is landing, the buffer rubber pads from the two sides to the middle contact with the ground or the platform in turn and squeeze the spring 18 for buffering.

The utility model installs a buffer pad 7 and a buffer frame 5 at the bottom of the drone 1. Due to the different heights of the buffer pads 7, during the landing of the drone 1, the buffer pads 7 on both sides are first in contact with the ground or the platform, and the middle buffer pad 7 is the last to contact with the ground or the platform. After the middle pad is buffered, the buffer frame 5 contacts the ground and the platform, achieving a step-by-step buffering effect and improving the buffering quality.
