Problems solved by technology
[0002] UAV is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. Civilian UAV has important applications in aerial photography, agriculture, plant protection, disaster relief and other fields; UAV needs to take off and land Shock absorption is used to protect the fuselage. The landing gear currently used is mostly fixed landing gear. When the drone lands, the landing gear will transmit the vibration generated when the landing gear contacts the ground to the fuselage, causing vibration and damage to the fuselage.

Embodiment Construction
[0022] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:
[0023] Such as figure 1 , a multi-stage buffer landing gear UAV, including a fuselage 1, a propeller 3 and a landing gear 2, the landing gear 2 includes at least three support rods 21, and the support rods 21 are hinged on the fuselage 1 On the side, the level of the end of the support rod 21 away from the fuselage 1 is higher than the level of the other end, and the end of the support rod 21 away from the fuselage 1 is provided with a leg 22, and the leg 22 is vertical. The first elastic mechanism 11 is arranged between the support rod 21 and the side of the fuselage 1. One end of the first elastic mechanism 11 is fixedly connected to the fuselage 1, and the other end is connected to the fuselage 1. The lower surface of the support rod 21 is fixedly connected.

The invention relates to a multistage buffer undercarriage unmanned aerial vehicle comprising a fuselage, propellers and an undercarriage. The undercarriage comprises at least three supporting rods which are hinged to the side surface of the fuselage, and the horizontal heights of the ends, away from the fuselage, of the supporting rods are larger than those of the other ends of the supporting rods. Supporting feet are arranged at the ends, away from the fuselage, of the supporting rods and are vertically arranged. A first elastic mechanism is arranged between the supporting rods and the sidesurface of the fuselage, one end of the first elastic mechanism is fixedly connected with the fuselage, and the other end of the first elastic mechanism is fixedly connected with the lower surfaces ofthe supporting rods. Multistage buffer structures are arranged, and thus damage to the fuselage when the unmanned aerial vehicle lands can be avoided.
Description
technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a multi-stage buffer landing gear unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. Civilian UAV has important applications in aerial photography, agriculture, plant protection, disaster relief and other fields; UAV needs to take off and land Shock absorption is used to protect the fuselage. The landing gear currently used is mostly fixed landing gear. When the drone lands, the landing gear will transmit the vibration generated when the landing gear contacts the ground to the fuselage, causing vibration and damage to the fuselage. . Contents of the invention [0003] Based on this, it is necessary to provide a multi-stage buffer landing gear UAV, including a fuselage, a propeller and a landing gear, the landing gear includes at least three support rod...
