Problems solved by technology

[0003] The current drones are more intelligent and popular, but when they are in use, they often need to be controlled by humans during the landing process. The drone itself cannot sense the distance from the landing point, so that newcomers are in operation. It often leads to insufficient control of the landing distance of the UAV, and the danger of crashing due to excessive speed. Moreover, when the current UAV lands, the buffer effect at the bottom is not good, which often causes the UAV to collide with the ground, which is harmful to the UAV. cause damage
The invention patent with the publication number CN112093037A provides a landing device for a rotor UAV, which includes N landing legs evenly arranged on the lower end surface of the shell and a vertical adsorption module; the landing legs include telescopic rods, sleeves, and fixing plates , a movable plate and a buffer spring; the direct-facing adsorption module includes pistons, pistons, threaded rods, motors, driving gears, driven gears, fixed bearings, and M vacuum suction cups, which enable the rotor drone to land on uneven surfaces through landing legs The ground can still maintain a horizontal state in an instant, and the rotor UAV is adsorbed on the vertical surface through the vertical surface adsorption module. The structure is simple and easy to use, but the landing device cannot measure the landing distance for precise positioning and landing.
The authorized notification number is CN207232767U utility model patent, which provides a UAV landing device for harsh landing environments. A motor is installed on each axis of the UAV body, and a rotor is installed on the rotor of the motor. The device also includes a power supply Module, signal conditioning module, processor module and communication module, the distance sensor is set on each axis of the rotor installed on the body of the UAV, and the distance from each distance sensor to the rotor is equal. The focus of this device is to solve the ground The problem of being uneven and unable to land safely, its structural design does not take into account the buffering and protection of drones and landing devices

Abstract

The invention provides an unmanned aerial vehicle landing device with electric wave distance measurement guidance. The device comprises a connecting disc connected with the bottom of an unmanned aerial vehicle power disc and a mounting disc connected with the connecting disc through multiple sets of buffering supporting rod assemblies. The mounting disc is of a circular ring structure, the middle of the mounting disc is provided with a through receiving opening, the top of the receiving opening is provided with an electric wave induction device, the bottom of the mounting disc is provided with a plurality of sets of supporting legs, an annular cavity is formed in the circular ring structure of the mounting disc, and a control ring is rotationally connected into the annular cavity; the control ring is connected with the supporting legs through a transmission assembly, so that the supporting legs can be stretched outwards or folded inwards. The unmanned aerial vehicle landing device not only has an electric wave ranging guiding function and can realize accurate positioning landing, but also has an excellent buffering effect, can realize stable protection on the unmanned aerial vehicle and the landing device, and is simple in structure, convenient to store and carry and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of drones, and relates to a landing device for drones. Background technique [0002] With the continuous development of science and technology, drone technology has been greatly improved in recent years, and many intelligent and multi-functional unmanned aerial vehicles have emerged. In response to the needs of transmitting information and monitoring in some small areas, unmanned aerial vehicles are getting more and more attention. It is a new concept aircraft in rapid development, which has the advantages of flexible maneuverability, quick response, unmanned flight, and low operation requirements; the use of drones has been expanded to three major fields: military, scientific research, and civilian use. Specifically, it is widely used in fields such as electric power, communication, meteorology, agriculture, ocean, exploration, photography, disaster prevention and reduction, crop yield estimation, anti-dru...
