Drone undercarriage of which rotation direction has damping and drone

Abstract

The invention discloses a drone undercarriage of which the rotation direction has damping and a drone. The drone undercarriage comprises a steering engine mounting box which is supported on a shock absorption device through a rotary shaft, a steering engine is arranged in the steering engine mounting box, the output end of the steering engine is connected with the rotary shaft through a linkage mechanism, the shock absorption device can be driven by the rotary shaft to change the direction, and the bottom of the shock absorption device is connected with drone wheels through a supporting frame;the shock absorption device comprises a first hinge and a second hinge which are arranged at an interval up and down and hinged together, several arc elastic ropes are arranged in an interval space between the first hinge and the second hinge, the arc direction of the arc elastic ropes is the pressure direction, the arc elastic ropes are fixed to the surfaces of the first hinge and the second hinge through an upper pressing plate and a lower pressing plate respectively, a hinging joint is arranged at the hinged point of the first hinge and the second hinge, and the hinging joint is provided with an opening and provided with a pin shaft for connection. By means of the drone undercarriage, the problem that the drone jolts and bounces up and down is solved, the damage to a gear of the steering engine can be prevented, the windward resistance is small, and more endurance can be obtained.

Description

technical field [0001] The invention relates to the field of UAV manufacturing, in particular to a UAV landing gear with damping in the rotation direction and the UAV. Background technique [0002] With the rapid development of industrial technology, the application of drones has become more and more extensive, and it has occupied an important position in various fields, and there are many new demands for accessories of drones. At present, the landing gear mechanisms of small and medium-sized fixed-wing UAVs are various, but the structural principles are similar, usually consisting of a wheel and a spring shock absorber (or gas spring) plus a fixed structure. When the UAV is taking off and landing, due to the condition of the runway surface, the attitude of the aircraft at that time is different, which will cause the UAV to vibrate. The shock absorption effect of the landing gear is particularly important at this time. The usual landing gear will transmit the impact force ...

AI Technical Summary

Problems solved by technology

When the wheel is turning in the direction of rotation, since there is no damping in the rotating square, a large impulse directly acts on the steering gear, causing damage to the steering gear
