Description

Technical Field

[0001] The present application relates to the field of drones, and in particular, to a drone with a crash protection structure. Background Art

[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device. With the development of drone technology, drones are being used more and more widely. For example, drones can be used in aerial photography, agriculture, plant protection, disaster relief, surveying and mapping, and film and television shooting.

[0003] During the flight, drones are prone to crashing due to signal interference, battery power failure, and software and hardware failures. However, in related drone technologies, the bottom of the drone is only fixed with outriggers to support the drone. The structure of the outriggers is relatively simple, and the legs lack a certain buffer structure. In the event of a crash, the buffering performance of the outriggers is poor, and the drone cannot be effectively buffered and protected, which can easily cause damage to the drone. In addition, the outriggers are fixed and cannot be folded, which is inconvenient for the storage of the drone. Utility Model Content

[0005] An embodiment of the present application provides a drone with a crash protection structure, including a drone body and a buffer component.

[0006] The lower surface of the drone body is rotatably provided with supporting legs, and a plurality of the supporting legs are provided, and the plurality of the supporting legs are evenly distributed in a circle.

[0007] The buffer assembly includes a central connecting sleeve, an elastic member and a knob bolt. There are a plurality of elastic members, one end of each of which is rotatably connected to the central connecting sleeve. There are a plurality of knob bolts, each of which is fixedly connected to the other end of each of the elastic members in a one-to-one manner. The threads of each of the knob bolts are respectively and one-to-one passed through the leg bodies of each of the supporting legs.

[0008] In a specific embodiment, the bottom ends of several of the supporting legs are each provided with a foot, and the foot is configured to be cylindrical.

[0009] In a specific implementation scheme, one side of several of the supporting legs is provided with a Velcro hook surface, and the lower surface of the drone body is provided with a Velcro fur surface. There are several Velcro fur surfaces, and several of the Velcro fur surfaces are respectively provided in one-to-one correspondence with several of the Velcro hook surfaces.

[0010] In a specific implementation, a plurality of the elastic members are each provided with a rotating shaft at one end, and the plurality of the rotating shafts are each rotatably connected to the central connecting sleeve, and the plurality of the rotating shafts are each rotatably penetrated through the sleeve wall of the central connecting sleeve.

[0011] In a specific embodiment, a connecting hole is provided on the sleeve wall of the central connecting sleeve, and a plurality of the connecting holes are provided, and the plurality of the connecting holes are evenly distributed in a circle, and a plurality of the rotating shafts respectively rotate and pass through the interior of the plurality of the connecting holes, and the rotating shafts are rotatably connected to the hole walls of the connecting holes.

[0012] In a specific embodiment, the top wall of the central connecting sleeve is provided with a first elastic buffer pad, and the bottom wall of the central connecting sleeve is provided with a second elastic buffer pad.

[0013] In a specific embodiment, the plurality of elastic members are springs, and the first elastic buffer pad and the second elastic buffer pad are elastic rubber washers.

[0014] In a specific implementation manner, the leg bodies of several of the supporting legs are provided with threaded holes, the threaded holes are evenly distributed in a circle, and the corresponding threads of several of the knob bolts penetrate through the interiors of the threaded holes one by one.

[0015] The beneficial effect of the utility model is that the utility model obtains a drone with a crash protection structure through the above design. When in use, when the drone body crashes, the several support legs contact the ground. Under the pressure of the drone body, the several support legs spread apart from each other, and then stretch the several elastic parts, so as to provide buffering protection for the crash of the drone body. When the drone body is not in use, the knob bolt can be rotated to make the knob bolt withdraw from the interior of the support leg, and then the central connecting sleeve and the several elastic parts can be disassembled, and then the support leg can be rotated toward the drone body, and then the support leg can be folded, so as to facilitate the storage of the drone body. On the one hand, the crash of the drone body can be more effectively buffered, so that the drone body is not easily damaged. On the other hand, the support legs can be folded for convenient storage, which is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
