Unmanned aerial vehicle accidental falling speed-reducing and damping device

Abstract

An unmanned aerial vehicle accidental falling speed-reducing and damping device comprises a square box, wherein the bottom of the square box is open; a sliding plate is horizontally arranged in the square box; a pull rope and at least two compression springs are arranged between the upper surface of the sliding plate and the inner wall of the top of the square box; the upper ends and the lower ends of the compression springs are separately fixedly connected with the top of the square box and the upper surface of the sliding plate; the lower surface of the sliding plate is fixedly connected with an air bag positioned in the square box; a high-pressure helium tank, a controller and an electronically controlled rope cutting mechanism are arranged on the inner wall of the top of the square box; the controller is provided with an accelerated speed sensor and a wireless signal receiver; the electronically controlled rope cutting mechanism is positioned on one side of the upper portion of thepull rope; the accelerated speed sensor and the wireless signal receiver are connected with the controller through data lines; and the controller is separately connected with an electronic control valve and the electronically controlled rope cutting mechanism through a control cable. Safety guarantee is provided for an unmanned aerial vehicle, safety reliability is high, economic loss of a user of the unmanned aerial vehicle is reduced to a maximum extent, and the safety for preventing the unmanned aerial vehicle from dropping and smashing people and objects on the ground is ensured.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a deceleration and shock absorption device for accidental fall of an unmanned aerial vehicle. Background technique [0002] At present, UAVs have been more and more widely used, and UAVs have appeared in military reconnaissance, traffic monitoring, agricultural spraying pesticides, forest fire warning and other fields. With the popularization and application of drones, crashes occur from time to time due to subjective and objective reasons such as unskilled control technology, misuse, climate, flight environment, battery power failure, etc. of drone controllers. [0003] At present, the parachute in the UAV protective equipment also plays a certain protective role, but when the above-mentioned subjective and objective conditions of the UAV crash occur when the UAV is flying at low altitude, the parachute cannot be fully deployed due to time and space ...

AI Technical Summary

Problems solved by technology

[0003] At present, the parachute in the UAV protective equipment also plays a certain protective role, but when the above-mentioned subjective and objective conditions of the UAV crash occur when the UAV is flying at low altitude, the parachute cannot be fully deployed due to time and space problems, and it cannot achieve its due effect. protective effect

[0004] Even if there are sufficient time and space conditions to satisfy the full deployment of the parachute, when the falling environment is complex, it will inevitably cause damage to the drone, which will bring economic losses to the drone holder and also damage the ground. people, buildings or other objects
