Foldable landing gear structure

Abstract

The invention discloses a foldable landing gear structure. The foldable landing gear structure comprises a lifting connecting rod, an internal shrinkage control device, a machine lower half part, a control panel, a fixing bolt, a lower connecting lug, an upper connecting lug, a machine upper half part and a foldable shrinkage frame, wherein the bottom of the machine upper half part is fixedly connected with the top of the machine lower half part, the internal shrinkage control device is installed in the machine upper half part, the two ends of the bottom of the foldable shrinkage frame are connected into the machine upper half part and fixedly connected with the interior of the internal shrinkage control device, the left end of the upper connecting lug is welded to the right end of the machine upper half part, and the right end of the machine lower half part is vertically connected with the left end of the lower connecting lug. The device can well buffer impact force generated during fast landing of a drone and plays a part in protecting the drone, and meanwhile, the foldable landing gear structure can automatically shrink, so that use convenience of the foldable landing gear structure is improved.

Description

technical field [0001] The invention relates to the field of landing gear structures, in particular to a foldable landing gear structure. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and its own program control device. At present, the domestic UAV market is hot. UAVs have gradually expanded from the initial military use to the consumer field. The degree of recognition and demand is also gradually rising. The take-off and landing control is particularly important during the operation of the UAV. The landing gear of the existing UAV is mostly fixed on the arm or the surface of the UAV body by screw fastening or extrusion on the outer surface. This kind of landing gear structure is greatly impacted when the aircraft lands too fast, and cannot play a buffer role when the drone fails to fly. Moreover, the fixed landing gear takes up a lot of space, and the space cannot be effectively used when used and stored. [0003] A...

Problems solved by technology

This kind of landing gear structure will be greatly impacted when the aircraft lands too fast, and it will not be able to play a buffer role when the drone fails to fly. Moreover, the fixed landing gear takes up a lot of space, and the space cannot be effectively used when used and stored.

[0003] At present, the foldable landing gear structure has to bear the impact force generated by the rapid landing of the UAV when it is in use, and cannot play a good buffer role for the UAV, reducing the use value of the device
