[0002] With the international development demand for intelligent and unmanned operations, the research and development of intelligent unmanned equipment has ushered in a booming vitality. Among them, the monitoring, loading, hovering, cruising and other functions of unmanned aerial devices, as well as their flexible and low-cost characteristics, have been greatly promoted and applied in agriculture, forestry, animal husbandry, sideline production and fishery industries. Therefore, the study of the take-off and landing methods and angles of unmanned aerial devices is particularly urgent and important. This is conducive to the optimization and improvement of the upgrading of flying devices, and also helps unmanned aerial devices to develop faster in all walks of life.

[0003] In the past, unmanned aerial devices were usually operated with human assistance during the take-off and landing process.

In addition, the impact of the final velocity of the unmanned aerial device on the landing point during the landing process can easily damage the device itself. At the same time, the unknown landing angle causes the device to leave the landing range, resulting in an inability to land effectively and posing a certain safety threat to the surrounding environment.

[0039] In this embodiment, referring to Figure 4 and Figure 6, a sliding track 12 is provided at the upper end of the launch rack 6. A sliding fixing block 13 is slidably mounted on the sliding track 12. A sliding plate 14 is provided on the sliding fixing block 13. The sliding plate 14 is fixed to the sliding fixing block 13 by a spring hook 20, so that the sliding plate 14 is stably mounted on the sliding fixing block 13.

[0040] In this embodiment, referring to Figure 4 and Figure 5 , a speed increasing mechanism 7 is provided on the launch rack 6. The speed increasing mechanism 7 is used to adjust the initial speed of the sliding fixing block 13. The speed increasing mechanism 7 includes a pneumatic cylinder 9, an air pressure bottle 10, two moving pulleys 71, a fixed pulley 72 and a traction rope 73. The pneumatic cylinder 9 is fixed at a position near the rear end inside the frame of the launch rack 6. The air pressure bottle 10 is fixed at a position near the rear end inside the frame of the launch rack 6. The air pressure bottle 10 is communicated with the pneumatic cylinder 9.

One end of the traction rope 73 is fixedly connected to the end wall at the front end inside the frame of the launch rack 6, and the other end passes through the front end of the sliding track 12 and is connected to the sliding fixing block 13. The traction rope 73 also sequentially surrounds and is sleeved on the moving pulley 71, the fixed pulley 72 and the moving pulley 71 and passes through the front end of the sliding guide rail and is connected to the sliding fixing block 13, thus forming a transmission route.

[0041] By changing the air pressure in the air pressure bottle 10, the extending speed of the pneumatic cylinder 9 is controlled, and then the speed of the traction rope 73 is transmitted and increased through the fixed pulley 72 and the moving pulley 71 to meet the different requirements of the flying device 22 for the initial speed and improve the take-off success rate of the flying device 22.

[0042] In this embodiment, referring to Figure 4 and Figure 5 , two groups of proximity switches 19 are provided at the front end of the launch rack 6.

[0043] In this embodiment, a buffer member 8 is provided at the front end of the sliding track 12. When the sliding fixing block 13 slides to the position of the buffer member 8, the kinetic energy of the sliding fixing block 13 is absorbed by the buffer member 8, so that the speed of the sliding fixing block 13 slows down. At this time, the sliding plate 14 overcomes the elastic force of the spring hook 20 by its own inertia, so that the sliding plate 14 and the sliding fixing block 13 are unlocked, and the sliding plate 14 and the flying device 22 are separated together to realize the take-off process of the flying device 22.

[0046] The working process of this embodiment: The mobile flying device launching platform is pushed to a designated position through the moving wheels 1, the supporting screw rod 2 is landed to bear force stably, the control motor 16 is started to control the lifting electric cylinder 5 to lift the telescopic frame 3 to a predetermined height. At the same time, the telescopic frame 3 rises along the telescopic stabilizing rod 4 to realize the adjustment of the height of the launching frame 6; further control the flipping electric cylinder 11, and by reading the angle value on the rotary encoder 18, make the launching frame 6 erected to a designated departure angle, install the flying device 22 on the sliding plate 14, lock the sliding plate 14 and the sliding fixing block 13 through the spring lock hook, check that the limit electromagnet 21 and the sliding fixing block 13 are in a locked state, adjust the flight attitude of the flying device 22 through the bolt knobs on both sides of the sliding fixing block 13 and tighten and fix it. Subsequently, remotely control the unlocking of the limit electromagnet 21 and the sliding fixing block 13; then open the valve of the air cylinder 10, the compressed air enters the pneumatic cylinder 9, quickly pulls the piston rod, and the traction rope 73 realizes transmission through two movable pulleys 71 and a fixed pulley 72, quickly driving the sliding fixing block 13 to be pulled out along the sliding track 12. The flying device 22 and the sliding plate 14 slide along the sliding track 12 with the sliding fixing block 13. After the sliding fixing block 13 contacts the buffer member 8, it decelerates and stops. The sliding plate 14 overcomes the elastic force of the spring lock hook due to inertia, and separates the sliding plate 14 and the flying device 22 together; through this structure, the flying device 22 can be accurately assisted in launching and flying, or the speed, angle and height simulation tests of the takeoff and landing of the flying device 22 can be carried out by means of this platform.
