Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted unmanned aerial vehicles, and in particular to a vehicle-mounted unmanned aerial vehicle landing gear lifting and stabilizing device. Background Art

[0002] The landing gear of a UAV refers to the structural component that supports the UAV when taking off and landing on the ground. It has the important functions of supporting the aircraft, reducing the impact of landing, and providing a suspension device. When a vehicle-mounted UAV takes off and lands, it needs to rely on a carrier vehicle as a carrier. The existing vehicle-mounted UAV landing gear lifting and stabilization device generally drives the UAV to rise in height through simple lifting, allowing the UAV to move to a suitable take-off height, avoiding the UAV being restricted by the carrier vehicle.

[0003] The existing UAV landing gear is usually equipped with a single lifting structure to control its lifting and lowering. Due to the size of the landing gear, the side without the lifting structure is offset by gravity, affecting the level of the landing gear. At the same time, the existing vehicle-mounted landing gear is usually lifted vertically relative to the vehicle. The angle of the landing gear cannot be adjusted according to the different road conditions encountered by the vehicle, resulting in it being not in a horizontal state, affecting the take-off and landing of the UAV. When the UAV is used during vehicle driving, the wind force on the front side is relatively large, which is easy to affect the UAV landing gear, causing it to shake, thereby reducing the stability of the UAV take-off and landing.

[0004] Therefore, there is an urgent need for a vehicle-mounted UAV landing gear lifting and stabilization device to solve the above problems. Summary of the invention
