Problems solved by technology

[0005] In order to simplify the process or reduce the weight of existing light and small UAVs, the landing gear often uses carbon fiber tubes or injection-molded plastic parts. This type of landing gear is rigid, has poor cushioning and energy absorption characteristics, and has the problem of large landing impact load.

Embodiment 1

[0025] Such as figure 1 Shown, a kind of unmanned aerial vehicle undercarriage, described undercarriage comprises four legs, and four legs are cross-shaped and connected to the fuselage of unmanned aerial vehicle; Any one leg comprises buffer energy absorber 2 and tripod 3. One end of the buffer energy absorber 2 is connected to the drone, and the other end is connected to the tripod 3;

[0026] Such as figure 2 and image 3 As shown, the energy absorber 2 includes elastic sheets 2-1 and 2-3 and a damping layer 2-2, the damping layer is sandwiched between the two layers of elastic sheets, and the upper and lower layers of the energy absorber are elastic sheets.

[0027] The buffer energy absorber is in an upwardly arched arc shape. Several outriggers are evenly distributed in the circumferential direction and connected to the drone. One end of the tripod 3 is connected to the buffer energy absorber 2 , and the other end is connected to the upwardly bent support foot 4 . ...

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to an unmanned aerial vehicle undercarriage which comprises a plurality of supporting legs, and any supporting leg comprises a buffering energy absorber and a foot stool; one end of the buffer energy absorber is connected with an unmanned aerial vehicle, and the other end is connected with the foot stool; and the buffer energy absorber comprises elastic pieces and a damping layer, and the damping layer is clamped between the two elastic pieces. The unmanned aerial vehicle undercarriage is simple in process, low in cost and light in weight, has good buffering and energy absorbing characteristics and can be applied to vertical take-off and landing light unmanned aerial vehicles on a large scale.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a landing gear of a light and small vertical take-off and landing unmanned aerial vehicle. Background technique [0002] The main functions of the landing gear of vertical take-off and landing UAV include two points: 1) ground support when the UAV is parked; internal equipment. [0003] At present, in order to reduce structural weight and reduce manufacturing costs, light and small UAVs usually use rigid landing gear made of carbon fiber tubes or plastic parts, and are hard-connected to the fuselage, and the function is close to the support frame. Although this type of landing gear is simple in process and light in weight, when the landing speed is too high, the UAV will be subjected to a large impact load, and the UAV and airborne equipment are easily damaged. [0004] For vertical take-off and landing of light and small unmanned aerial vehicles, the developme...
