Problems solved by technology

[0003] During the landing process of the rotor UAV, due to environmental factors such as wind direction, uneven ground, and human manipulation errors, the landing process is not smooth, which makes the rotor UAV vulnerable to strong vibrations when it lands, which will damage the rotor. The delicate electronic equipment inside the drone poses a threat, so how to solve the problem of strong vibration when the rotor drone is landed is becoming more and more important

Embodiment 1

[0026] A composite UAV shock-absorbing base, such as figure 1 As shown, it includes a base 1, a shock-absorbing tripod 2 and a shock-absorbing box 3.

[0027] Wherein, the seat body 1 is configured as a plate, arranged horizontally when in use, and fixed on the drone, such as the bottom surface of the fuselage, by means of bolts, bonding, welding or the like.

[0028] Wherein, a plurality of shock-absorbing legs 2 are configured, and a plurality of shock-absorbing legs 2 are evenly arranged circumferentially on the same circumference of the bottom surface of the seat body 1, and the center of the circle is configured to coincide with the center of gravity of the drone to prevent rollover. In this embodiment, the shock-absorbing stand 2 includes a stand 21 hinged on the base 1 and a buffer spring 22 connected between the stand 21 and the seat 1; the upper end of the stand 21 is fixed with a pivot, and Ears are provided on the bottom surface or side of 1, and there are shaft h...

Embodiment 2

[0035] The difference between it and Embodiment 1 is: in this embodiment, if figure 1As shown, the shock-absorbing stand 2 also includes a roller 23 installed on the bottom of the stand 21 . And, when the stand 21 is at the supporting position, the roller 23 is positioned under the shock absorber 3, so that when the rotor drone lands, the roller 23 first touches the ground, and by setting the roller 23, the rotor drone can It is suitable for landing on various terrains, and avoids the situation that the shock-absorbing tripod 2 is embedded in the ground and cannot bounce up for shock-absorbing and buffering.

[0036] Simultaneously, in order to further improve the shock-absorbing and buffering effect of the shock-absorbing tripod 2, the configuration roller 23 is a rubber roller.

Embodiment 3

[0038] A drone such as figure 1 As shown, it is a rotor UAV, including a fuselage 4, a machine arm 5 and a rotor 6, wherein, the machine arms 5 are configured with four and symmetrically arranged, and each wing tip end of the machine arm 5 is fixedly equipped with a motor, The above-mentioned rotor 6 is fixed on the output shaft of each motor. In addition, the rotor UAV also includes the composite UAV shock-absorbing base disclosed in any of the above-mentioned embodiments, wherein the top of the seat body 1 in the composite UAV shock-absorbing base is fixedly connected to the UAV by bolts or welding. The bottom surface of the fuselage 4.

Abstract

The invention discloses a combined type unmanned aerial vehicle damping base and an unmanned aerial vehicle with the same, and belongs to the field of unmanned aerial vehicles. A plurality of damping foot stools are uniformly arranged on the same circumference of the bottom surface of the seat body in the circumferential direction; the damping foot stool comprises a supporting foot stand hinged to the seat body and a buffer spring connected between the supporting foot stand and the seat body, and the buffer spring is used for providing resistance for preventing the supporting foot stand from rotating towards one side of the seat body when the supporting foot stand is impacted by external force and providing elastic force for keeping the supporting foot stand at a supporting position for supporting the seat body when the supporting foot stand is not impacted by the external force; a damping box is arranged in the circumference defined by the multiple damping foot stools so that the supporting foot stools can be kept at the supporting position after abutting against the side wall of the damping box. The damping box comprises a box body and a damping plate, the top of the box body is fixed to the bottom face of the base, and the damping plate is fixed to the bottom of the box body. The invention is simple in structure, light in weight and good in damping effect, the stability of the unmanned aerial vehicle can be improved, and equipment damage is avoided.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a composite unmanned aerial vehicle shock-absorbing base and an unmanned aerial vehicle equipped with it. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. According to the application field, UAV can be divided into military and civilian. For military use, UAVs are divided into reconnaissance aircraft and target drones; for civilian use, UAVs are currently used in aerial photography, agriculture, plant protection, miniature selfies, express transportation, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, and news reports. , Power inspection, disaster relief, film ...
