[0002] An unmanned aerial vehicle, abbreviated as "UAV", is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device, or is completely or intermittently autonomously operated by an on - vehicle computer. During the outdoor use of a UAV, due to reasons such as terrain and environment, the support of the UAV cannot stably contact the ground, resulting in the inability of the UAV to take off and land smoothly. Therefore, an airport that can assist the UAV in taking off and landing is needed. The charging ports of the existing airports are fixed. After the existing UAV lands on the take - off and landing airport, it cannot effectively align with the charging port, making it inconvenient for the UAV to dock with the charging port of the airport. Thus, when charging the UAV, it is necessary to manually move the UAV to the charging port of the take - off and landing airport to perform the charging operation. However, using this method to move the UAV cannot achieve rapid moving and positioning during UAV charging and is not convenient for UAV charging operations. Content of the Utility Model

Detailed implementation method

[0026] The following further describes the specific implementation manners of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these implementation manners is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] As shown in Figure 1 , 2 , 3, 4, 6, 7, and 8, a drone landing and centering structure provided by the present utility model includes a landing platform 1. A first centering module 2 is provided on the bottom surface of the landing platform 1. A second centering module 3 is provided below the first centering module 2. The first centering module 2 and the second centering module 3 are arranged in an interleaved manner. The centering ends of the first centering module 2 and the second centering module 3 pass through the landing platform 1 and extend to the upper surface of the landing platform 1. A placement space 5 is formed between the centering ends of the first centering module 2 and the second centering module 3, so that the drone can land at the placement space 5.

[0028] A first slot 6 and a second slot 7 are opened inside the landing platform 1.

The centering end of the first centering module 2 passes through the first slot 6 and extends to the upper surface of the landing platform 1, and the centering end of the second centering module 3 passes through the second slot 7 and extends to the upper surface of the landing platform 1.

[0029] When centering the drone landed on the upper surface of the landing platform 1: First, the drone can be landed at the placement space 5, and then the first centering module 2 is started. Through the first centering module 2, the drone located at the placement space 5 can be moved in the Y-axis direction, so that the drone can be moved to the central axis in the width direction of the landing platform 1, and the centering operation in the width direction can be realized. Subsequently, the second centering module 3 is started. Through the second centering module 3, the drone located at the placement space 5 can be moved in the X-axis direction, so that the drone can be moved to the central axis in the length direction of the landing platform 1. Through the first centering module 2 and the second centering module 3, the drone can be moved to the middle of the landing platform 1, and the centering operation in the length direction can be realized, so as to realize the centering operation of the drone, thereby quickly positioning the drone and enabling the drone to better align with the charging port at the landing platform 1 to realize the charging operation;

[0030] At the same time, centering the drone can ensure that the drone is located at the center of the landing platform 1, effectively avoiding the risk of the drone falling from the landing platform 1 after landing.

[0031] Subsequently, a shutdown module 4 is provided on one side of the opposite end of the module 3 in the second pair. After the UAV completes the centering operation, the shutdown module provided on one side of the second pair of modules 3 can be started, and the physical power switch of the UAV can be accurately controlled through the swinging path of the shutdown module 4. In this way, the shutdown and startup of the UAV can be achieved by starting the second pair of modules 3, without the need to manually operate the shutdown and startup of the UAV.

[0032] As shown in Figure 1 , 2 , 3, 4, and 5, the first pair of centering modules 2 includes a first support plate 21, a first connecting rod 22, a first motor 23, a first transmission rack 24, a second transmission rack 25, a first abutting member 26, and a second abutting member 27. The first support plate 21 is arranged on the bottom surface of the takeoff and landing platform 1. A first connecting rod 22 is arranged between the takeoff and landing platform 1 and the first support plate 21. First sliding components 28 and 29 are arranged on both sides of the upper surface of the first support plate 21. First transmission racks 24 and 25 are respectively arranged on the upper surfaces of the sliding parts of the first sliding component 28 and the second sliding component 29. The first transmission rack 24 and the second transmission rack 25 are arranged oppositely. A first motor 23 is arranged on the bottom surface of the first support plate 21. The output end of the first motor 23 passes through the first support plate 21 and is provided with a first transmission gear 210. The first transmission gear 210 meshes with the first transmission rack 24 and the second transmission rack 25. First abutting members 26 and 27 are respectively arranged on the sides of the first transmission rack 24 and the second transmission rack 25 away from the first transmission gear 210.

[0033] When it is necessary to perform centering operation on the UAV landed at the placement space 5 in the width direction: the first motor 23 can be started first, and the first transmission gear 210 is driven to rotate by the first motor 23. Subsequently, the first transmission gear 210 meshes with the first transmission rack 24 and the second transmission rack 25. In this way, when the first transmission gear 210 rotates, the first transmission rack 24 and the second transmission rack 25 can be driven to move in two directions. Subsequently, when the first transmission rack 24 and the second transmission rack 25 move, the first abutting member 26 and the second abutting member 27 can be respectively driven to move in two directions;

[0034] It should be noted that when the first motor 23 rotates forward, the first transmission gear 210 can be driven to rotate forward. When the first transmission gear 210 rotates forward, the first transmission rack 24 and the second transmission rack 25 can be driven to approach the central axis in the length direction of the takeoff and landing platform 1. In this way, the first abutting member 26 and the second abutting member 27 can be made to approach each other, thereby realizing the centering operation on the UAV at the placement space in the width direction;

[0035] On the contrary, it is known that when the first motor 23 rotates in the reverse direction, it can drive the first transmission gear 210 to rotate in the reverse direction. When the first transmission gear 210 rotates in the reverse direction, it can drive the first transmission rack 24 and the second transmission rack 25 to move away from the central axis in the length direction of the lifting platform 1, so that the first abutting member 26 and the second abutting member 27 can move away from each other, thereby releasing the centering operation in the width direction of the UAV at the placement space.

[0036] The first abutting member 26 and the second abutting member 27 are arranged oppositely, and the structures of the first abutting member 26 and the second abutting member 27 are the same. The first abutting member 26 includes a first mounting seat 261, a cover plate 262, an abutting block 263 and a spring member 264. The first mounting seat 261 is arranged at the end of the first rack on the side far from the first transmission gear 210. A cover plate 262 is arranged on the upper surface of the first mounting seat 261. An opening 265 is arranged on the side of the cover plate 262 facing the first transmission gear 210. The abutting block 263 is arranged in the cover plate 262 through the opening 265. A spring member 264 is arranged between the abutting block 263 and the inner wall surface of the cover plate 262.

[0037] When the first abutting member 26 and the second abutting member 27 come into contact with the UAV, they can be connected to the UAV through the abutting block 263. Subsequently, through the mutual cooperation of the abutting block 263 and the spring member 264, the abutting block 263 can achieve buffering when contacting the UAV, reducing damage to the surface of the UAV.

[0038] Preferably, silica gel pads are arranged on the surfaces of the first abutting member 26 and the second abutting member 27 facing the UAV.

[0039] As shown in the appendix Figure 1 、 2As shown in FIGS. 6, 7, 8, and 9, the second pair of centering modules 3 includes a second support plate 31, a second connecting rod 32, a second motor 33, a third transmission rack 34, a fourth transmission rack 35, a third abutting member 36, and a fourth abutting member 37. The second support plate 31 is disposed at the bottom of the first pair of centering modules 2. The upper surface of the second support plate 31 is provided with a second connecting rod 32. The second support plate 31 is connected to the bottom surface of the lifting platform 1 through the second connecting rod 32. The upper surface of the second support plate 31 is provided with a third sliding assembly 38 and a fourth sliding assembly 39 on both sides. The upper surfaces of the sliding portions of the third sliding assembly 38 and the fourth sliding assembly 39 are respectively provided with a third transmission rack 34 and a fourth transmission rack 35. The third transmission rack 34 and the fourth transmission rack 35 are disposed opposite to each other. The bottom surface of the second support plate 31 is provided with a second motor 33. The output end of the second motor 33 passes through the second support plate 31 and is provided with a second transmission gear 310. The second transmission gear 310 meshes with the third transmission rack 34 and the fourth transmission rack 35. A third abutting member 36 and a fourth abutting member 37 are respectively disposed on the sides of the third transmission rack 34 and the fourth transmission rack 35 away from the second transmission gear 310. A shutdown module 4 is disposed on the side of the third abutting member 36 away from the second transmission gear 310.

[0040] When it is necessary to perform centering operation on the length direction of the drone landed at the placement space 5: the second motor 33 can be started first, and the second transmission gear 310 is driven to rotate by the second motor 33. Subsequently, the second transmission gear 310 meshes with the third transmission rack 34 and the fourth transmission rack 35. Thus, when the second transmission gear 310 rotates, the third transmission rack 34 and the fourth transmission rack 35 can be driven to move in two directions. Subsequently, when the third transmission rack 34 and the fourth transmission rack 35 move, the third abutting member 36 and the fourth abutting member 37 can be respectively driven to move in two directions, and the shutdown module 4 on one side of the third abutting member 36 can be driven to move at the same time.

[0041] It should be noted that when the second motor 33 rotates forward, the second transmission gear 310 can be driven to rotate forward. When the second transmission gear 310 rotates forward, the third transmission rack 34 and the fourth transmission rack 35 can be driven to approach the central axis in the width direction of the lifting platform 1. Thus, the third abutting member 36 and the fourth abutting member 37 can be made to approach each other, so as to realize the centering operation on the width direction of the drone at the placement space 5, and the shutdown module 4 can be made to approach the drone at the placement space, so as to facilitate the shutdown module 4 to perform shutdown and start operations on the drone;

[0042] On the contrary, it is known that when the second motor 33 rotates in reverse, it can drive the second transmission gear 310 to rotate forward. When the second transmission gear 310 rotates in reverse, it can drive the third transmission rack 34 and the fourth transmission rack 35 away from the central axis in the width direction of the landing platform 1, so that the third transmission rack 34 and the fourth transmission rack 35 can move away from each other, thereby being able to release the centering operation in the width direction of the drone at the placement space, and can synchronously drive the shutdown module 4 away from the drone at the placement space 5.

[0043] The third abutting member 36 and the fourth abutting member 37 are arranged opposite to each other. The structures of the third abutting member 36 and the fourth abutting member 37 are the same. The third abutting member 36 includes a second mounting seat 361 and a top rod 362. The second mounting seat 361 is arranged at the end of the third rack on the side far from the second transmission gear 310. The top rod 362 is arranged on the upper surface of the second mounting seat 361. The shutdown module 4 is arranged on one side of the top rod 362. When the third abutting member 36 and the fourth abutting member 37 contact the drone, they can be connected to the drone by abutting against the top rod 362;

[0044] Preferably, the top rod 362 is made of silica gel.

[0045] As shown in Figure 1 、 2 、6, 7, 8, 9 and 10, the shutdown module 4 includes a mounting box 41, a third motor 42, a rotating rod 43, a rotating disk 44 and a swing arm 45. The mounting box 41 is arranged on the upper surface of the top rod 362. A connecting plate 47 is arranged at the lower part of the mounting box 41, so that the mounting box 41 is connected to the second mounting seat 361 through the connecting plate 47. A fixing frame 46 is arranged inside the mounting box 41. The third motor 42 is arranged inside the fixing frame 46. The output end of the third motor 42 is provided with the rotating rod 43. A rotating disk 44 is arranged on one side of the rotating rod 43. A clamping groove 441 is arranged on one side of the rotating disk 44. The rotating rod 43 is clamped in the clamping groove 441. A swing arm 45 is arranged on one side of the rotating disk 44;

[0046] A convex column 442 is arranged on the side of the rotating disk 44 close to the swing arm 45. A through hole 451 is arranged at one end of the swing arm 45 close to the rotating disk 44. The convex column 442 is inserted into the through hole 451. In this way, through the mutual cooperation of the convex column 442 and the through hole 451, when the rotating disk 44 rotates, it can drive the swing arm 45 to rotate. A protruding part 452 is arranged at the other end of the swing arm 45.

[0047] When the drone is shut down after the centering operation is completed: The third motor 42 can be started first, and the rotating rod 43 is driven to rotate by the third motor 42. Due to the mutual engagement between the rotating rod 43 and the rotating disk 44, when the rotating rod 43 rotates, the rotating disk 44 can be driven to rotate synchronously. When the rotating disk 44 rotates, the swing arm 45 can be driven to rotate, so that the protruding part 452 of the swing arm 45 can abut against the physical power switch of the drone, thereby realizing the shutdown operation of the drone.
