Problems solved by technology

[0003] However, since drones transmit and interact with information through wireless control, they are vulnerable to program failures, hardware failures, electromagnetic interference, hacking, etc.
When severely affected, it may even lead to major accidents such as crashes
At this time, the UAV not only cannot complete the established target tasks, but may even cause physical damage to the UAV.
In particular, pesticide spraying drones are large in size, heavy in weight, and carry toxic substances. If an accidental crash occurs, not only will the drone be damaged, but it may also cause losses to the person and property on the opposite side.

Embodiment 1

[0051] Such as Figure 1-6 As shown, a protection system for improving the safety of the physical layer of the drone includes a drone 5; the drone 5 has a support frame 1 and a rotating wing; the support frame 1 includes legs 10, two adjacent A crossbeam 17 is connected between the legs 10; a buffer layer is provided at the bottom of the legs 10, and the buffer layer is made of elastic material; the buffer layer includes multiple layers: the first buffer layer, the second buffer layer Two buffer layers and a wear-resistant layer; the first buffer layer is a rubber layer, the second buffer layer is a polyurethane foam layer, and the wear-resistant layer is a melamine resin layer.

[0052] The polyurethane layer is arranged at the bottom of the rubber layer; the spraying of the melamine resin is the bottom of the polyurethane foam layer, thus the rubber layer, the polyurethane foam layer and the melamine resin layer are sequentially arranged from top to bottom.

[0053] There a...

Embodiment 2

[0058] The difference between this embodiment and the first embodiment is that buffer wings 4 are provided on both sides of the fuselage of the drone, and the buffer wings 4 can rotate on the drone 5, and buffer wings 4 are provided with buffer Cloth 8, the other end of the buffer cloth 8 is connected with the UAV 5. The buffer fin 4 is connected to the UAV 5 through a rotating shaft 13, and the rotating shaft is connected to a motor 16 through a gear structure. The motor 16 is connected with the controller of the drone 5 .

[0059] The gear structure is a worm wheel 14 and a worm screw 15, the worm wheel 14 is connected with the rotating shaft 13, the output shaft of the motor 16 is connected with the worm screw 15, and the worm wheel and the worm screw mesh with each other.

Embodiment 3

[0061] This embodiment is different from Embodiments 1 and 2 in that a high-pressure gas cylinder is arranged in the drone 5, and an air nozzle 2 is arranged on the drone 5, and the gas outlet of the nozzle 2 is vertically The air nozzle 2 is connected to the high-pressure gas cylinder through the first air pipe 3 .

[0062] The left and right sides of the fuselage of the drone 5 are provided with air nozzles 2, and the air nozzles 2 on both sides are arranged symmetrically. Described jet nozzle 2 has four, is all at the bottom of unmanned aerial vehicle 5. The gas in the high-pressure gas cylinder is air, and the pressure in the high-pressure gas cylinder is 2.0-5.6 bar. The drone 5 is provided with a ranging sensor, and the ranging sensor is used to measure the distance between the drone and the ground.

[0063] The fuselage of the drone 5 is provided with a protective strip 18, the protective strip 18 includes a protective plate 20, the number of the protective plate 20 i...

Abstract

The invention discloses a protection system for improving the safety of a physical layer of an unmanned aerial vehicle. The unmanned aerial vehicle is provided with a supporting frame and rotary wings. The supporting frame comprises supporting legs, and a cross beam is connected between every two adjacent supporting legs. Buffer layers are arranged at the bottoms of the supporting legs; the buffer layers comprise a first buffer layer, a second buffer layer and a wear-resistant layer; the first buffer layer is a rubber layer, the second buffer layer is a polyurethane foam layer, and the wear-resistant layer is a melamine resin layer; the polyurethane layer is arranged at the bottom of the rubber layer; the melamine resin is sprayed at the bottom of the polyurethane foam layer; by setting physical protection measures, when the unmanned aerial vehicle is accidentally influenced and falls, the unmanned aerial vehicle is protected and prevented from the physical level, serious damage to the unmanned aerial vehicle during accidental falling is relieved, and the safety performance of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention belongs to the technical field of protection in unmanned aerial vehicles, and in particular relates to a protection system for improving the safety of the physical layer of the unmanned aerial vehicle. Background technique [0002] With the development of artificial intelligence and other technologies, more and more drones have entered people's lives. They are not only used for shooting, photography, monitoring security, terrain survey, etc., but also for many technologies such as spraying pesticides and logistics delivery. field. UAVs generally use remote control equipment or their own automatic driving technology to achieve the purposes of shooting, photography, monitoring security, terrain survey, spraying pesticides, and logistics delivery. [0003] However, since UAVs transmit and interact with information through wireless control, they are vulnerable to program failures, hardware failures, electromagnetic interference, hacking, etc...
