Undercarriage applied to four-axis unmanned aerial vehicle

Abstract

The invention discloses an undercarriage applied to a four-axis unmanned aerial vehicle. Front undercarriages are mounted on two sides of the front end of an unmanned aerial vehicle body. A front heightening part is arranged at the bottom end of each front undercarriage. A front mounting part is arranged at the top end of each front heightening part. A guide plate is mounted in the middle of eachfront mounting part. First fasteners are mounted on two sides of each guide plate. Rear undercarriages are mounted on two sides of the rear end of the unmanned aerial vehicle body. A rear heighteningpart is arranged at the bottom end of each rear undercarriage. A support is mounted in the middle of each rear heightening part. A third fastener is mounted at the top end of each support. A rear mounting part is arranged at the top end of each rear heightening part. Second fasteners are mounted on two sides of each rear mounting part. The undercarriage has the advantages that the unmanned aerialvehicle body is in snap joint with the front undercarriages through the first fasteners, and is in snap joint with the rear undercarriages through the second fasteners and the third fasteners, so thatthe undercarriage is simple to operate, firm in snap joint, and convenient to mount, demount, store and carry.

Description

technical field [0001] The invention relates to the technical field of an auxiliary device for an unmanned aerial vehicle, in particular to a landing gear applied to a four-axis unmanned aerial vehicle. Background technique [0002] The four-axis UAV is an unmanned aircraft with four rotors that is operated by radio remote control equipment and its own program control device. It has low cost, high efficiency, strong survivability, good maneuverability, and convenient use. Due to its advantages, it is widely used in various fields such as aerial photography, agriculture, forestry and plant protection, express transportation, power inspection, etc. The landing gear is a necessary support system for the four-axis UAV to take off and land, and its quality plays an important role in the safety of the UAV. Most of the existing landing gears are simple in structure and troublesome to install. Not only the overall strength is low, the service life is short, but also the shock absorp...

[0002] The four-axis UAV is an unmanned aircraft with four rotors that is operated by radio remote control equipment and its own program control device. It has low cost, high efficiency, strong survivability, good maneuverability, and convenient use. Due to its advantages, it is widely used in various fields such as aerial photography, agriculture, forestry and plant protection, express transportation, power inspection, etc. The landing gear is a necessary support system for the four-axis UAV to take off and land, and its quality plays an important role in the safety of the UAV. Most of the existing landing gears are simple in structure and troublesome to install. Not only the overall strength is low, the service life is short, but also the shock absorption is relatively poor. In addition, most of the landing gears are easy to cause scratches to the fuselage when they are installed. , less practical
