Retractable landing gear for unmanned aerial vehicle

Abstract

The invention provides a retractable landing gear for an unmanned aerial vehicle. The retractable landing gear for the unmanned aerial vehicle comprises a base and a gear body; the base is mounted atthe bottom of the unmanned aerial vehicle; a rotating shaft is arranged at the upper end of the gear body; the rotating shaft is mounted on the base; a buffering device is mounted at the lower end ofthe gear body; a rotating wheel is mounted at the lower end of the buffering device; a connecting rod is hinged at the middle part of the gear body; a rotating piece is arranged at one end, far away from the gear body, of the connecting rod; a track is arranged on the external side of the rotating piece; the track is mounted on the base; and a fastening device is mounted on the rotating piece. Theretractable landing gear for the unmanned aerial vehicle has the advantages that good vibration absorbing effect is realized, the appearance is beautiful, the retraction and extension are convenient,the landing gear retracts and extends by using the connecting rod, the position of the landing gear is fixed by using the fastening device during using, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a retractable landing gear of an unmanned aerial vehicle. Background technique [0002] During the take-off and landing process, the UAV generally adopts the flight method of gliding and landing. During the take-off and landing process, the landing gear of the UAV is an important component in the aircraft take-off and landing process. Its weight, buffer capacity, installation method and reliability are important. There are strict technical requirements, otherwise it will have an adverse impact on the entire take-off and landing process, and even cause damage to the drone. It is fixed on the fuselage with rubber bands or screws. Although the structure is simple, its performance is poor, and it is easy to cause deformation, deviation, and breakage of the landing gear. Since the landing gear does not have a good shock absorption device, during the rough landing proc...

Problems solved by technology

[0002] During the take-off and landing process of the UAV, the flight mode of skid lift and slide is generally adopted. During the take-off and landing process, the UAV landing gear is an important part of the aircraft take-off and landing process. There are strict technical requirements, otherwise it will have an adverse effect on the entire take-off and landing process, and even cause damage to the UAV. At this stage, the common UAV landing gear is generally made of steel wire or carbon plate, which is made by bending process. It is fixed on the fuselage with rubber bands or screws. Although the structure is simple, its performance is poor, and it is easy to cause deformation, deviation, and breakage of the landing gear. Since the landing gear does not have a good shock absorbing device, during a rough landing, It often causes damage to the fuselage, and the landing gear is difficult to repair; the appearance of the landing gear is simple and rough, which affects the overall appearance of the UAV, and the existing landing gear has little retractable function, so we designed a UAV The retractable landing gear is used to solve the above problems
