Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) anti-falling devices, in particular to an unmanned aerial vehicle (UAV) anti-falling device. Background Art

[0002] Drones are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. According to their application areas, drones are currently widely used in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspections, disaster relief, film and television shooting, and creating romance.

[0003] Most existing drones land on a fixed landing gear at the bottom of the drone and do not have a buffer device. During flight, drones often lose connection with the control equipment due to factors such as the environment in which they are located, causing them to fall, which in turn causes irreversible damage to the drone. Therefore, a drone anti-fall device is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4As shown in the figure, the utility model relates to a drone anti-falling device, including a drone anti-falling device, which comprises a sliding rod 1, a supporting rod 2 and a telescopic rod 3. There are two groups of sliding rods 1. The lower surfaces at both ends of the sliding rod 1 are connected with first hinge blocks 6. The upper end of the telescopic rod 3 is installed inside the first hinge block 6 and can rotate. The outer side of the lower end of the telescopic rod 3 is installed with a second hinge block 11. One side of the second hinge block 11 is fixedly connected to the surface of the supporting rod 2. Upper baffles 7 and lower baffles 10 are respectively fixedly installed on the outer surfaces of the upper end and the lower end of the telescopic rod 3. A second spring 9 is arranged inside the lower baffle 10 and the upper baffle 7. The second spring 9 is installed outside the telescopic rod 3.

[0021] When in use, one end of the supporting rod 2 expands outwards, so that the other end moves inwards. The movement of the other end of the supporting rod 2 drives the slider 15 to slide on the surface of the sliding rod 1, and at the same time squeezes the first spring 14 inwards, thereby achieving a buffering effect.

[0022] Please refer to Figure 4 , sliders 15 are installed on the surface of the sliding rod 1. There are two groups of sliders 15, and they can slide on the surface of the sliding rod 1. A first spring 14 is arranged inside the two groups of sliders 15. The first spring 14 is installed outside the sliding rod 1. By arranging the sliders 15 and the first spring 14, a buffering effect can be achieved, greatly reducing the damage to the drone caused by falling.

[0023] [[ID=?]]Please refer to Figure 3 , the lower surface of the slider 15 is connected with a third hinge block 12. One end of the supporting rod 2 is installed inside the third hinge block 12 and can rotate. By arranging the third hinge block 12, it is used to hinge-connect the slider 15 and the third hinge block 12.

[0024] Please refer to Figure 3 , rollers 13 are installed on both sides of one end of the supporting rod 2. The rollers 13 can rotate on the surface of the supporting rod 2. By arranging the rollers 13, the landing stability can be improved.

[0025] Please refer to Figure 1 , mounting plates 5 are fixedly connected to the surfaces at both ends of the two groups of sliding rods 1. One side of the mounting plate 5 is connected with a connecting plate 4. One end of the connecting plate 4 is connected to one side of another mounting plate 5. By arranging the mounting plate 5, it is convenient to install this device on the bottom of the drone through bolts. By arranging the connecting plate 4, it is used to fixedly connect multiple mounting plates 5.

[0026] Working principle: The utility model is an anti-falling device for a drone. First, the device is installed at the bottom of the drone through the mounting plate 5. When the drone falls, affected by gravity, the roller 13 first contacts the ground and rotates. At this time, due to the continuous downward extrusion of the gravity of the drone itself, one end of the support rod 2 is driven to expand outwards. By the outward expansion of one end of the support rod 2, the telescopic rod 3 is extruded upwards. The contraction of the telescopic rod 3 drives the lower baffle 10 and the upper baffle 7 to squeeze the second spring 9 inwards, so as to achieve the buffering effect. By the outward expansion of one end of the support rod 2, the other end thereof moves inwards. The movement of the other end of the support rod 2 drives the slider 15 to slide on the surface of the slide rod 1 and at the same time squeezes the first spring 14 inwards, thereby achieving the secondary buffering effect.
