The linear guide rail 3 drives the connecting slide 9 to move toward or in the opposite direction at the same time, so as to drive the left cover shell 4 and the right cover shell 8 to engage with each other or to be pulled apart in the opposite direction;

[0022] As a further implementation of this embodiment, Figure 1 , Figure 2 and Figure 3As shown, a slow-descent platform 6 is arranged on the top of the platform 2, and the slow-descent platform 6 is parallel to the top surface of the platform 2. An infrared rangefinder 7 is arranged at the middle position of the top of the slow-descent platform 6. When the UAV lands, the infrared rangefinder 7 detects the distance between the bottom of the UAV and the slow-descent platform 6. A lifting electric cylinder 12 is arranged at the middle position between the top of the take-off and landing platform body 1 and the top of the platform 2. The top of the lifting electric cylinder 12 is fixedly connected to the middle position of the bottom of the slow-descent platform 6. When the bottom of the UAV is infinitely close to the slow-descent platform 6, the lifting electric cylinder 12 drives the slow-descent platform 6 to descend slightly slower than the descent speed of the UAV, so that the UAV lands smoothly. The drone can land slowly and stably on the slow-descent platform 6. Stabilizing sleeves 10 are provided on both sides of the top of the platform 2. Stabilizing guide rods 11 are provided on both sides of the bottom of the slow-descent platform 6. The stabilizing guide rods 11 are symmetrically arranged at the bottom end of the slow-descent platform 6. The bottom ends of the stabilizing guide rods 11 pass through the inside of the stabilizing sleeve 10. The stabilizing guide rods 11 can be lifted and slid in the stabilizing sleeve 10. The stabilizing guide rods 11 can lower the slow-descent platform 6 and slide downward in the inside of the stabilizing sleeve 10 to stabilize the slow-descent platform 6, thereby making the drone land more smoothly and safely, avoiding the drone from bouncing and falling after falling due to excessive descent speed, and having strong feasibility.

[0023] When the drone is landing on the platform 2, the infrared rangefinder 7 detects the distance between the bottom of the drone and the slow-down platform 6. When the bottom of the drone is infinitely close to the slow-down platform 6, the lifting electric cylinder 12 drives the slow-down platform 6 to descend slightly slower than the descent speed of the drone, so that the drone lands smoothly and stably on the slow-down platform 6. At the same time, the stabilizing guide rod 11 slides downward inside the stabilizing sleeve 10 to stabilize the slow-down platform 6.

[0024] As a further implementation of this embodiment, Figure 1-4 As shown, a card-joint sealing assembly is provided on the inner side of the left cover shell 4 and the right cover shell 8, and the card-joint sealing assembly includes a "U"-shaped docking card slot 5, which is provided at the edge of one side of the left cover shell 4, and a "U"-shaped docking card plate 14 is provided at the edge of one side of the right cover shell 8, and the docking card plate 14 is matched with the inside of the docking card slot 5, and the docking card plate 14 is subsequently engaged into the inside of the docking card slot 5 when the left cover shell 4 and the right cover shell 8 are closed, and a sealing gasket 13 is provided on the inner and outer sides of the docking card plate 14, and the card-joint is sealed by the sealing gasket 13, so that the docking joint of the left cover shell 4 and the right cover shell 8 is more stable and tight, and the phenomenon of water leakage at the docking joint in rainy and snowy weather is avoided, and the protective performance of the device shield is optimized;

[0025] The linear guide rail 3 drives the connecting slide 9 to pull the left cover shell 4 and the right cover shell 8 to move relative to each other, and when the docking is closed, the docking card plate 14 is then clamped into the inside of the docking card slot 5, and the clamping part is sealed by the sealing gasket 13, so that the docking part between the left cover shell 4 and the right cover shell 8 is more stable and tight;

[0026] Specific working principle:

[0027] When using the take-off and landing device, when the drone needs to land on the device, the linear guide rail 3 drives the connecting slide 9 to move in the opposite direction, thereby pulling apart the left cover 4 and the right cover 8. Subsequently, when the drone is landing on the platform 2, the infrared rangefinder 7 detects the distance between the bottom of the drone and the slow-descent platform 6. When the bottom of the drone is infinitely close to the slow-descent platform 6, the lifting electric cylinder 12 drives the slow-descent platform 6 to descend slightly slower than the descent speed of the drone, so that the drone lands smoothly and stably on the slow-descent platform 6. At the same time, the stabilizing guide rod 11 slides downward inside the stabilizing sleeve 10 to stabilize the slow-descent platform 6. After the drone lands, the linear guide rail 3 drives the connecting slide 9 to move toward each other, thereby driving the left cover 4 and the right cover 8 to close. At the same time, the docking card plate 14 is connected to the inside of the docking card slot 5, and the card joint is sealed by the sealing gasket 13, so that the docking point between the left cover 4 and the right cover 8 is more stable and tight, thereby providing safety protection for the drone.
