[0025] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] As described in the background technology, drones in the prior art are usually reusable, and it is necessary to ensure the safe recovery of drones. In order to safely recover drones in the event of an emergency, a solution is adopted for drones to be equipped with parachutes to reduce the damage to drones caused by unexpected falls or emergency landings. Simply carrying a parachute on a drone, the parachute rope is fixed to the surface of the drone body. During the normal flight of the drone, the emergency parachute and the parachute rope will generate additional air resistance that affects the performance of the drone. When the drone opens the emergency parachute due to accidental installation, the moment of opening the parachute will have a great impact on the parachute rope hanging point. Limited by the size and weight requirements, the strength of the drone body itself is not particularly high. When the structural strength of the parachute rope hanging point is not enough, it is easy to be damaged, causing the parachute rope to fall off the drone and tear the drone skin.

[0027] In order to solve the above problems, the present application creatively proposes a UAV parachute device and a UAV, in which the parachute is accommodated in a platform opened on the top of the UAV body to avoid the force detachment during the normal flight of the UAV, affecting the safety of the UAV flight and causing damage to the UAV, and the parachute rope is connected to the arm connecting part of the UAV body, and the parachute rope hanging point is located at the arm connection. The structural strength is high, which effectively avoids the parachute rope hanging point from being greatly impacted by the moment the parachute is opened, thereby causing secondary damage to the UAV.

[0028] The solution of the present application will be described in detail below in conjunction with the accompanying drawings and various embodiments.

[0029] Embodiment 1: This embodiment provides a parachute device for a drone, referring to Figure 1 and Figure 2 As shown, the device includes a drone body 1 and a parachute 2; the parachute 2 includes a parachute body 21, an umbrella rope 22 and a guide parachute (not shown); a platform 3 for accommodating the parachute 2 is provided on the top of the drone body 1; one end of the umbrella rope 22 is connected to the parachute body 21, and the other end is connected to the arm connector 11 of the drone body 1.

[0030] Reference Figure 3 As shown, the arm connector 11 is a component used to connect the drone body to the drone arm. The drone arm is the root of the drone wing. Since the drone wing rotates at high speed during flight, driving the drone to fly and generate a large impulse, the drone arm connector requires extremely high strength. Therefore, the parachute rope hanging point is set on the arm connector, which has high structural strength and is not easy to damage the drone body. The parachute is set in a platform opened on the drone body, which effectively avoids the force detachment during normal flight of the drone, affecting the safety of the drone flight and causing damage to the drone.

[0031] In one embodiment, the platform 3 includes a parachute cabin 31 and a parachute rope channel 32 that are connected;

[0032] The parachute body 21 is accommodated in the parachute compartment 31, and each parachute rope channel 32 is accommodated in a parachute rope 22; the opening of the parachute compartment 31 is covered with a parachute compartment opening cover 12, and the opening of the parachute rope channel 32 is covered with a parachute rope opening cover 13. The parachute ropes and the parachute body are accommodated in different parts of the platform 3 of the fuselage body 1, which can increase the speed of the parachute when it is opened, and avoid the parachute ropes and the parachute body being entangled or even knotted together, thereby preventing the opening failure.

[0033] Preferably, the parachute rope channel 32 is arranged around the parachute compartment 31. The parachute opens more smoothly, and the impact force generated on the drone body 1 at the moment of opening is relatively more uniform. Figure 1 and Figure 2As shown, the parachute 2 has four parachute ropes 22, corresponding to four parachute rope channels 32, and the four parachute rope channels 32 are arranged around the parachute compartment 31. The parachute rope hanging points are dispersed, the parachute ropes are dispersed quickly, and the success rate of parachute opening during landing is high.

[0034] More preferably, the hatch cover 12 and the rope cover 13 are both detachably connected to the surface of the drone body 1. The hatch cover 12 and the rope cover 13 are fixed to the surface of the drone body 1. When the parachute 2 is to be opened, the hatch cover 12 is forced to fall off, the parachute body 21 is pulled out of the cabin, the rope 22 is pulled outward by the parachute body 21, and the rope cover 13 is torn open by the rope 22. The hatch cover 12 and the rope cover 13 can be re-bonded and reused, and the utilization rate is high.

[0035] More preferably, the umbrella hatch cover 12 is integrally formed with the umbrella rope cover 13. The umbrella hatch cover 12 and the umbrella rope cover 13 are integrally formed, so that the umbrella hatch cover 12 and the umbrella rope cover 13 can be recycled and reused together after they fall off.

[0036] More preferably, the umbrella hatch cover 12 and the umbrella rope cover 13 are both conformal skins, which are consistent with the shape of the covered platform 3, saving materials and having a more beautiful appearance.

[0037] More preferably: the umbrella hatch cover 12 and the umbrella rope cover 13 are both carbon fiber composite covers, which have high strength and corrosion resistance and a long service life.

[0038] Preferably, when the parachute 2 is accommodated in the platform 3, the dimension of the parachute 2 in the depth direction of the platform 3 is less than or equal to the depth of the platform 3, so as to prevent the parachute 2 from protruding from the platform 3, thereby reducing the resistance effect on the drone during normal flight.

[0039] Preferably, the guide parachute is connected to the parachute body 21, and the guide parachute is connected to a side of the umbrella hatch cover 12 facing the umbrella cabin 31. When the parachute is opened, the umbrella hatch cover 12 falls off, and the guide parachute connected thereto falls off, thereby pulling the parachute body 21 connected to the guide parachute out of the umbrella cabin 31.

[0040] The parachute device for parachuting of unmanned aerial vehicles provided in this embodiment uses carbon fiber composite materials for the hatch cover and the rope cover, which are of high strength, corrosion resistance and long service life. After the rope cover is torn off by the parachute rope, it can be reused by re-bonding, and the utilization rate is high. The hatch and rope are buried in the fuselage, and the unmanned aerial vehicle is less affected when flying normally. The rope is provided with a separate rope channel and a rope cover. When the parachute is opened, the rope will not cause serious damage to the skin of the unmanned aerial vehicle. The rope hanging point is located on the arm connector with extremely strong structural strength, which can effectively bear the impact generated when the parachute is opened. The rope hanging points are dispersed, the rope dispersion speed is fast, and the success rate of parachute opening is high during landing.

[0041] Embodiment 2: This embodiment provides a drone, which includes the drone parachute device described in Embodiment 1.
