Description

Technical Field

[0002] At present, in the existing technology, as the UAV technology develops more and more maturely, UAVs are widely used in various fields such as agriculture, aerial photography, search and rescue, and monitoring. Generally, the aircraft carries a variety of payloads such as pods, loudspeakers, radars, etc., which can track, locate, telemeter, and transmit real-time data to ground equipment. The launch method of UAVs can be catapult take-off, wheeled take-off and landing, or vertical take-off and landing, and the demand for launch and recovery devices is increasing. Vehicle-mounted UAV launch and recovery devices are favored by more users because of their better environmental adaptability and maneuverability. The vehicle-mounted launch and recovery device uses a vehicle to move the drone to a designated area for operation. When the operation is completed, the drone lands at a designated location and is fixed. Common vehicle-mounted drone launch and recovery devices are usually set inside the car or on the roof. The placement and take-off and landing of the drone are achieved by adapting the roof and the cabin. Recovering and placing the drone on the roof will cause the overall space of the vehicle to become larger, and the driver cannot always observe the roof situation. The drone is prone to accidents during the driving process of the vehicle. The drone launch and recovery device inside the car is usually provided with a homing mechanism, a locking mechanism and other auxiliary recovery mechanisms, which occupies a large car space. In addition, one car is usually provided with a launch and recovery device, and multiple drones cannot be placed, and the car space utilization rate is low.

[0084] In this embodiment, the drone storage box 2 includes a box body 201 and a drone support column 202. The box body 201 is provided with a cavity, and the number of drone support columns 202 is four. The drone support columns 202 are arranged in the cavity, and one end of the drone support column 202 is connected to the box body 201.

[0086] In this embodiment, when the drone's arm is placed on the arc structure 401, the lifting and fixing mechanism 5 continues to descend. Then, in the absence of support, the drone's arm will rise relative to the drone until the arm locking structure 204 is locked, and the initial processing of the drone is completed.

[0087] The movable terminal 2032 cooperates with the magnetic terminal 2031. When the drone needs to be recovered, the movable terminal 2032 contacts the magnetic terminal 2031. After power is turned on, the two terminals are attracted, the drone is locked, and the recovery process is completed, thereby realizing the rapid locking and recovery of the drone and improving the recovery efficiency.

[0088] In one embodiment, the working process of a vehicle-mounted multi-rotor UAV launch and recovery device of the present invention is as follows:

[0089] like Fig.12 As shown, this is the initial state of a vehicle-mounted multi-rotor UAV launch and recovery device of the present invention. In the initial state, the UAV is inside the UAV storage box 2, and the separation disk mechanism 3 is placed next to the UAV storage box 2. When the vehicle-mounted multi-rotor UAV launch and recovery device needs to launch the UAV, the controller controls the magnetic terminal 2031 to lose its magnetism, and the servo motor 1051 drives the active pulley 1052 to rotate, thereby driving the belt 1053 to move. During the movement, the belt 1053 drives the driven pulley 1054 to move, and the driven pulley 1054 further drives the screw body 1032 to rotate. When the screw body 1032 rotates, the screw nut 1033 moves in the vertical direction, and then drives the moving frame 503 to rise through the screw nut 1033. The moving frame 503 drives the guide rod nut 1022 to move and makes the moving frame rise and fall more smoothly through the guide rod nut 1022. The UAV landing board 501 lifts the UAV. At this time, the separation disk 303 is still placed next to the UAV storage box 2. As shown Figures 13 to 17 As shown, when the lower end of the UAV's arm exceeds the height of the arc structure 401, the rotary motor 305 rotates, and through the meshing transmission of the active gear 307 and the driven gear 309, the separation plate 303 is driven to rotate to the bottom of the UAV. At this time, the height of the separation plate 303 is lower than the lower end of the UAV's arm. The lifting motor 312 drives the elevator 302 to rotate, and then the output screw rod pushes the separation plate 303 to rise, and then drives the separation plate 303 to push the UAV's arm open. When the UAV's arm is opened to a position exceeding the axis of the arc structure 401. At this time, the servo motor 1051 drives the active pulley 1052 to rotate, thereby driving the belt 1053 to move. During the movement, the belt 1053 drives the driven pulley 1054 to move. The driven pulley 1054 further drives the screw body 1032 to rotate, thereby driving the motion frame 503 to descend through the screw nut 1033. The UAV descends along with the UAV landing board 501 on the lifting support column 502. Here, because the support bearing 403 is sleeved on the arc structure 401, the arc structure 401 can rotate relative to the flattening mechanism support 404, and then the UAV's arm is placed on the arc structure 401. At the same time, Fig.18As shown, the lifting motor 312 drives the lift 302 to rotate, so that the output screw drives the separation plate 303 to descend to the initial height, and the rotary motor 305 rotates, and through the meshing transmission of the driving gear 307 and the driven gear 309, drives the separation plate 303 to rotate to the side of the drone storage box 2, that is, the separation plate 303 returns to the initial state. Fig.19 As shown, as the drone descends, the deployment angle of the drone's arms increases continuously until they are completely flattened, and the locking structure 204 locks the arms, and the drone is in a take-off position.

[0090] When the vehicle-mounted multi-rotor drone launch and recovery device needs to recover the drone, the drone lands on the drone landing board 501, the staff folds the blades and the arms into the storage state, and the servo motor 1051 drives the active pulley 1052 to rotate, thereby driving the belt 1053 to move. The belt 1053 drives the driven pulley 1054 to move during the movement, and the driven pulley 1054 further drives the screw body 1032 to rotate, and then drives the motion frame 503 to descend through the screw nut 1033. The drone descends with the drone landing board 501, and the moving terminal 2032 on the drone contacts the magnetic terminal 2031. The controller controls the magnetic terminal 2031 to be magnetized, thereby causing the moving terminal 2032 to be attracted to the magnetic terminal 2031, the drone is locked, and the recovery process is completed.
