Problems solved by technology
[0003] However, the existing UAV landing gears all adopt rigid brackets
When the UAV lands on an uneven ground, it is prone to tipping over, causing damage to the UAV in severe cases, and due to the lack of cushioning of the rigid support, even a normal landing may cause damage to the precision equipment on the UAV

The invention discloses a landing gear for an unmanned aerial vehicle with good shock absorbing effect, comprising a body provided with a rotor; the lower surface of the machine body is provided withgrooves near four corners, and a main pipe is arranged at the bottom of the groove, an extension rod is slidably connected to the inside of the main pipe, and the bottom ends of the extension rods areall welded with diagonal rods, a notch is reserved in the middle of the bottom of the inclined bar, and a rectangular groove is formed on the lower surface of the cross bar near the middle of the upper part. The groove bottom of the rectangular groove is clamped with a disc block, and the lower surface of the disc block is fixed with a compression spring, and the top end of the compression springis clamped with a convex block. The invention can compress the bump on the top of the spring to land first when the machine body is inclined to descend and is about to land, thereby generating a rebound force, which can prevent the machine body from continuing to fall to the ground in an inclined position, and has a good shock absorbing effect.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a landing gear for an unmanned aerial vehicle with good shock absorption effect. Background technique [0002] The landing gear of domestic rotor UAVs mostly adopts the method of two poles on both sides. This common structure can basically meet the take-off and landing performance requirements of small multi-rotor UAVs, but there are problems of single structure, poor support strength, and poor stability. Lean forward and roll over. The fixed-wing vertical take-off and landing UAV has a large take-off weight, and has high requirements on the performance of the landing gear and the stability of the aircraft during landing. [0003] But existing unmanned aerial vehicle landing gear, all adopts rigid support. When the UAV lands on an uneven ground, it is prone to tipping over, causing damage to the UAV in severe cases, and due to the lack of cushioning of the rigi...
