[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device, or is operated completely or intermittently autonomously by an onboard computer. Currently, drones are widely used in police, urban management, agriculture, geology, meteorology, electricity, disaster relief, video shooting and other industries.

[0003] When a drone lands, if the landing speed is too fast, a strong impact force will be generated. After the strong impact force is transmitted to the drone, it is easy to cause impact damage to the drone. At the same time, the strong impact is easy to cause damage to the internal parts of the drone, thereby reducing the life of the drone. Therefore, a drone with a buffer carrier is needed to solve this problem. Utility Model Content

There are symmetrically distributed slides 8, and the opposite outer walls of the two slides 8 on the same side are fixedly connected with the first straight racks 9, and the left and right end surfaces inside the two installation cavities 6 are fixedly connected with a connecting shaft 10, and the outer walls of the two connecting shafts 10 are rotatably connected with gears 11, and the four first straight racks 9 are respectively meshed with the two gears 11, and the upper end surfaces of the two support plates 3 are fixedly connected with the second straight racks 12, and the two second straight racks 12 are respectively meshed with the two gears 11, and the outer walls of the four second slide bars 7 are sleeved with the first springs 13, and the outer walls of the four first slide bars 4 are sleeved with the second springs 14.

[0021] In this embodiment: when the drone body 1 lands, when the support plate 3 contacts the ground, under the action of the impact force, the support plate 3 moves upward relative to the buffer frame 2, thereby driving the first slide bar 4 to move upward along the slide groove 5, thereby compressing the second spring 14, and the impact force is first buffered by the second spring 14. At the same time, the support plate 3 drives the second spur rack 12 to move upward, thereby driving the gear 11 to rotate clockwise, and the clockwise rotation of the gear 11 further drives the two first spur racks 9 to move relative to each other, thereby driving the two slide plates 8 to slide relative to each other along the second slide bar 7, and the two slide plates 8 further compress the first spring 13, and the impact force is further buffered by the first spring 13. The utility model performs double buffering of the impact force by the first spring 13 and the second spring 14, and has a good buffering effect, which solves the problem that the internal parts of the drone are easily damaged and the service life is reduced due to the impact when the drone lands in the past.

[0022] As a technical optimization solution of the present utility model, the upper end surfaces of the four first sliding rods 4 are fixedly connected to the limiting blocks 15 .

[0023] In this embodiment, the first slide bar 4 is restricted inside the slide groove 5 by the limiting block 15 to prevent the first slide bar 4 from escaping from the slide groove 5 .

[0024] As a technical optimization solution of the present invention, two rectangular holes are opened on the lower end surface of the buffer frame 2, and the two second spur racks 12 extend to the inside of the buffer frame 2 through the two rectangular holes respectively.

[0025] In this embodiment, two rectangular holes are provided on the lower end surface of the buffer frame 2 , so that the two second spur racks 12 extend to the inside of the buffer frame 2 through the two rectangular holes respectively and mesh with the gear 11 .

[0026] As a technical optimization solution of the present invention, the face width of the gear 11 is greater than the sum of the face widths of the first spur rack 9 and the second spur rack 12 .

[0028] As a technical optimization solution of the present utility model, the buffer frame 2 is U-shaped.

[0029] In this embodiment, by setting the buffer frame 2 to be U-shaped, the wind resistance of the buffer frame 2 during flight can be reduced, thereby saving energy.

[0030] As a technical optimization solution of the present invention, rubber pads 16 are provided on the lower end surfaces of the two support plates 3 .

[0031] In this embodiment, rubber pads 16 are provided on the lower end surfaces of the two support plates 3, so that nearly half of the impact force during landing can be buffered, and the buffering effect is good.

[0032] The working principle of the utility model is as follows: when the drone body 1 lands, the support plate 3 first contacts the ground, and under the action of the impact force, the support plate 3 moves upward relative to the buffer frame 2, thereby driving the first slide bar 4 to move upward along the slide groove 5, thereby compressing the second spring 14, and first buffering the impact force through the second spring 14. At the same time, the support plate 3 drives the second spur rack 12 to move upward, thereby driving the gear 11 to rotate clockwise, and the clockwise rotation of the gear 11 further drives the two first spur racks 9 to move relative to each other, thereby driving the two slide plates 8 to slide relative to each other along the second slide bar 7, and the two slide plates 8 further compress the first spring 13, and further buffer the impact force through the first spring 13. The utility model performs double buffering of the impact force through the first spring 13 and the second spring 14, and has a good buffering effect, which solves the problem that the internal parts of the drone are easily damaged and the service life is reduced due to the impact when the drone lands in the past.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
