Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle aviation, and in particular relates to a remotely controlled unmanned aerial vehicle parachute. Background Art

[0002] With the rapid development of drone technologies, drones are being used more and more widely. If a multi-rotor drone crashes during flight, it is easy to damage the drone. Therefore, in order to prevent the drone from crashing after a malfunction, the drone is generally equipped with a suitable parachute. When the drone encounters a malfunction, the parachute will open and the drone will land slowly.

[0003] However, most existing parachutes for drones cannot change the trajectory of descent during descent and are easily affected by wind during descent, making the descent of the drone uncontrollable after the parachute is opened. If the area where the drone fails is not suitable for landing, the drone is vulnerable to damage even if the parachute is opened after the drone fails. Therefore, it is urgent to design a remote-controlled parachute that can change the descent trajectory of the drone after the parachute is opened by ground personnel, so as to achieve control of the landing location.

The lower servo connecting piece 1064 has a One end of the control device 103 is connected to the lower steering gear 1063 and the other end is connected to the lower connecting rod 1065, one end of the lower connecting rod 1065 is connected to the lower connecting buckle 1062 and the other end is connected to the lower steering gear connecting plate 1064, an isolation plate 1031 is provided above the control device 103, a battery 104 is fixed on the isolation plate 1031, four parachute rope holes 1092 are provided on the middle shell 109, an igniter 1091 is installed on the plane outside the middle shell 109, a parachute part 2 is installed on the plane outside the middle shell 109, and a fixed mounting belt 301 is installed on the fixed handle 102;

[0039] The parachute part 2 includes a parachute body 201, parachute ropes 202, a canopy 203, a bottom canopy 204, and a combustible paper sheet 207. The parachute body 201 is connected to the parachute ropes 202, one end of the parachute ropes 202 is connected to the parachute body 201, and the outer side wall of the canopy 203 is provided with a canopy pull ring 2032, one side of the canopy pull ring 2032 is connected to the canopy connecting rod 1021, one end of the canopy connecting rod 2021 is connected to the canopy pull ring 2032 and the other end is connected to a fixed The fixed handle 102 has two upper fixing columns 2031 on one side of the inner part of the umbrella cover 203. The lower part of the umbrella cover 203 is connected to the umbrella base cover 204. The bottom surface of the umbrella base cover 204 has four umbrella cover holes 205 and one vent hole 206. The umbrella base cover 204 is installed on the plane outside the middle shell 109. The inner part of the umbrella base cover 204 has two lower fixing columns 2041. The combustible paper sheet 207 is installed between the vent hole 206 and the igniter 1091.

[0040] The fixed mounting belt 301 is used to connect the fixed handle 102, and the parachute is fixed in the middle position of the drone 3. The timing of the parachute opening is set inside the control device 103. The control device 103 has an IMU inside, which can sense the movement state of the drone 3. By receiving the signal sent by the remote control to the receiver 108, the servo movement is controlled to drive the upper moving plate 105 and the lower moving plate 106 to move.

[0041] Reference Figure 8-10 When installing the parachute ropes 202, the four parachute rope holes 1092 and the four umbrella cover holes 205 are in one-to-one correspondence, so that the parachute ropes 202 can pass smoothly. There are four pairs of parachute ropes 202, of which two non-adjacent pairs of parachute ropes 202 connect the parachute body 201 and the upper mounting holes 1051, and the other two pairs of parachute ropes 202 connect the parachute body 201 and the lower mounting holes 1061; when connecting the parachute ropes 202, each parachute rope 202 passes through the umbrella cover hole 205 and the parachute rope hole 1092.

[0042] The control device 103 controls the upper servo 1053 and the lower servo 1063 to rotate the upper moving plate 105 and the lower moving plate 106, and then pulls the parachute rope 202 to change the shape of the parachute body 201, thereby changing the force direction of the parachute; and the side surfaces of the upper moving plate 105 and the lower moving plate 106 are perpendicular to each other, so after the parachute is opened, the drone 3 can move forward, backward, left and right.

[0043] The combustible paper 207 is a flammable material. After being ignited by the igniter 1091, a small range of high-pressure gas is generated, so that the umbrella body 201 can be smoothly opened. Glue is applied to the connection between the bottom cover 204 and the umbrella cover 203, and the contact surface between the upper fixing column 2031 and the lower fixing column 2041; after applying glue, when the drone 3 flies normally, the umbrella cover 203 will not be opened due to the bonding effect of the glue; and the high-pressure gas generated after the combustible paper 207 is burned can break through the adhesion of the glue, open the umbrella cover 203, and then smoothly open the umbrella body 201.

[0044] When the drone 3 fails and the parachute body 201 is opened, the warning light 101 will flash continuously to help the operator determine the moving direction of the drone 3 during the fall. The remote controller is used to send a signal to the receiver 108, and finally the trajectory of the drone 3 during the fall is controlled.

[0045] Working principle: The conditions for the drone 3 to crash are set in the control device 103. When the drone 3 encounters these conditions, the control device 103 can sense the crash of the drone 3, send a signal to the igniter 1091, ignite the combustible paper 207 to generate high-pressure gas, and then open the umbrella cover 203 and the parachute body 201 to prevent the drone 3 from falling quickly; then, the control device 103 receives the signal sent by the remote control to the receiver 108, controls the upper side servo 1053 and the lower side servo 1063 to drive the upper moving plate 105 and the lower moving plate 106 to move, and then pulls the parachute rope 202 to deform the parachute body 201, change the force direction of the parachute, and finally change the descending trajectory of the drone 3.

[0046] The above is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be thought of by a person skilled in the art within the technical scope disclosed by the utility model without creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
