DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment 1

[0033] As Figures 1 to 4 shown, a centering structure for an unmanned aerial vehicle provided by an embodiment of the present utility model is installed on the cabin of the unmanned aerial vehicle. The centering structure for the unmanned aerial vehicle includes:

[0034] A landing platform 10, where the landing platform 10 is a non-ferrous, sheet-shaped, and rigid structure;

[0035] Four groups of guiding components 20, where the guiding component 20 includes a guiding rod 21 and a guiding seat 22. The guiding rod 21 is fixedly connected to the landing platform 10 through the guiding seat 22. The four groups of guiding rods 21 are horizontally arranged, and the four groups of guiding rods 21 are arranged in a square;

[0036] A centering component 30 slidably connected to the guiding rod 21. The centering component 30 includes a sliding block 31 and a centering rod 32. Two sliding blocks 31 are slidably connected to each guiding rod 21. The two ends of the centering rod 32 are respectively fixedly connected to the sliding blocks 31 on the opposite sides. The centering rods 32 located on the same guiding rod 21 are arranged in parallel, and the distances between the centering rods 32 located on adjacent guiding rods 21 and the landing platform 10 are different;

[0037] Four groups of linear driving parts 40. Two driving blocks 42 are provided on the linear driving part 40. The two driving blocks 42 perform linear motion under the drive of the linear driving part 40, and the motion modes of the two driving blocks 42 are opposite / away from each other. A second magnet 43 is fixedly connected to the driving block 42, and a first magnet 33 is fixedly connected to the sliding block 31. The first magnet 33 and the second magnet 43 attract each other so that the sliding block 31 follows the centering rod 32 to move.

[0038] In this embodiment, after the unmanned aerial vehicle docks on the landing platform 10, the linear driving part 40 is started. The driving blocks 42 located on the same linear driving part 40 perform opposite motion. When the driving block 42 moves, the second magnet 43 located on the driving block 42 drives the sliding block 31 to slide on the guiding rod 21 by attracting the first magnet 33. When the sliding block 31 slides, it drives the centering rod 32 located on the same guiding rod 21 to perform opposite motion. When the centering rod 32 performs opposite motion, the centering rod 32 centers the unmanned aerial vehicle.

[0039] The centering structure of the drone disclosed in the embodiment of the present utility model drives the centering component 30 located outside the landing platform 10 to slide linearly by installing the linear driving part 40 inside the landing platform 10 and by the mutual adsorption of the second magnet 43 and the first magnet 33, so as to achieve the purpose of centering for the drone. Since the power between the centering component 30 and the linear driving part 40 is transmitted by magnetic force, there is no need to set up a power transmission channel inside and outside the landing platform 10, and the cabin of the drone can be completely enclosed, reducing the influence of wind and rain on the drone cabin, so that the drone can take off and land in windy and rainy weather without causing water to enter the cabin.

[0040] Specifically, in this embodiment, the landing platform 10 is made of plastic material, the thickness of the landing platform 10 at the sliding track of the second magnet 43 is 1 millimeter, and the distance between the second magnet 43 and the first magnet 33 and the landing platform 10 is less than 1 millimeter, so that the suction force between the second magnet 43 and the first magnet 33 is sufficient to drive the first magnet 33 to slide. The second magnet 43 and the first magnet 33 are made of strong magnetic materials, such as the second magnet 43 and the first magnet 33 are rubidium magnets.

[0041] The guide rod 21 is a smooth round rod, and the guide rod 21 is fixedly connected to the landing platform 10 through a guide seat 22. The guide seat 22 is a right-angle pipe, and the guide seat 22 is provided with feet connecting the landing platform 10. The feet are fixed to the landing platform 10 through fastening screws. The fastening screws pass through the landing platform 10 and are screwed tightly on the feet by threads. A rubber gasket is arranged between the fastening screws and the landing platform 10, and the rubber gasket plays a waterproof role. The guide rod 21 is fixedly connected to the guide seat 22 by interference fit;

[0042] The guide rod 21 and the guide seat 22 form a square frame. The guide seat 22 is at the four corners of the square frame, and the guide rod 21 is the four sides of the square frame;

[0043] Preferably, the thread of the fastening screw is also filled with sealant to further improve the sealing performance between the landing platform 10 and the feet.

[0044] The sliding block 31 is a square block, and a sliding hole is also arranged on the sliding block 31. The guide rod 21 is located in the sliding hole. A first installation groove with a belt is arranged on the surface of the sliding block 31 close to the landing platform 10. The first magnet 33 is fixedly connected to the first installation groove by gluing. The centering rod 32 is a strip-shaped rod, and the end of the centering rod 32 is fixedly connected to the end of the sliding block 31 far from the landing platform 10 through a screw;

[0045] Two sliding blocks 31 are slidably connected to each of the guiding rods 21. Two guiding rods 21 arranged on opposite sides are connected to two centering rods 32. The centering rods 32 connected to the same guiding rod 21 are arranged in parallel. The four centering rods 32 are arranged in a square shape. When centering the drone, the four centering rods 32 push the drone to move to a preset position.

[0046] As Figure 4 and Figure 5 shown, the driving block 42 is a square block. A second installation groove is provided on one side of the driving block 42 close to the landing platform 10. The second magnet 43 is fixedly connected to the second installation groove by gluing.

[0047] Preferably, third magnets 44 are further fixed on both sides of the driving block 42 with respect to the second magnet 43. There are three groups of the second installation grooves. The second installation grooves are arranged along the sliding track direction of the driving block 42. The third magnets 44 are fixedly glued in the second installation grooves. The magnetic pole setting direction of the third magnet 44 is opposite to the magnetic pole setting direction of the second magnet 43. Exemplarily, if the upward end of the second magnet 43 is the S pole, then the end of the first magnet 33 close to the second magnet 43 is the N pole, and the upward end of the third magnet 44 is the N pole. When the first magnet 33 and the second magnet 43 are misaligned, the driving block 42 repels the first magnet 33, enabling the first magnet 33 to move following the second magnet 43 and preventing the sliding block 31 from detaching from the lead screw 41.

[0048] It should be noted that since the first magnet 33 and the second magnet 43 are connected without contact, the magnetism of the first magnet 33 and the second magnet 43 is adjusted according to the weight of the drone. For example, when the weight of the drone is large, the first magnet 33 and the second magnet 43 with larger magnetism should be used. Necessarily, the second magnet 43 can be an electromagnet to provide a larger suction force, thereby preventing the first magnet 33 from detaching from the second magnet 43 and causing the problem of centering failure.

[0049] In this embodiment, the linear drive unit 40 further includes a lead screw 41 and a drive motor 45. The lead screw 41 is rotatably connected to the landing platform 10 through a shaft seat structure. The output end of the drive motor 45 is connected to the lead screw 41 through a coupling structure to drive its rotation. The drive motor 45 is fixed to the landing platform 10 or inside the cabin. A lead screw nut is provided on the lead screw 41, and the lead screw nut is fixedly connected to the drive block 42 through a screw. The landing platform 10 is provided with limit baffles on both sides of the drive block 42 to prevent the drive block 42 from rotating with the lead screw 41. When the lead screw 41 rotates, the lead screw 41 drives the drive block 42 to move linearly through the lead screw nut. The lead screw 41 is provided with two external threads with opposite helix directions, and two drive blocks 42 are connected to each lead screw 41. The two drive blocks 42 are located on the thread sections with different helix directions on the lead screw 41;

[0050] Since the first magnet 33 and the second magnet 43 are connected in a non-contact manner, when controlling the centering rod 32 to be centered, the drive motor 45 rotates a preset number of turns according to the size of the drone, so that the centering rod 32 pushes the drone to move to a preset position. When the cabin adapts to the drone, the rotation angle of the drive motor 45 is set according to the size of the drone. When centering, the drive motor 45 rotates from the preset angle, so that the drive block 42 moves from the initial position to the preset position. When releasing the drone, the drive motor 45 rotates in the reverse direction by a preset number of turns to return to the initial position;

[0051] It should be noted that in this embodiment, the shaft seat structure may not be installed on the landing platform 10, and may also be installed at other positions in the cabin.

[0052] Embodiment 2

[0053] As another embodiment of the present invention, the difference between this embodiment and Embodiment 1 is that the linear drive unit 40 may also be other structures. For example, the linear drive unit 40 is a belt drive structure. In this embodiment, the lead screw 41 is not included, and a synchronous belt is installed at the position of the lead screw 41. The drive motor 45 drives the synchronous belt to rotate, and the drive block 42 is fixed to different areas on the synchronous belt. When the synchronous belt rotates, the two drive blocks 42 approach or move away from each other. This structure can refer to the structure of an electric curtain.

[0054] Embodiment 3

[0055] As Figure 6 shown, as one of the embodiments of the present invention, this embodiment further provides a drone cabin, which includes the drone centering structure described in Embodiment 1, and further includes:

[0056] The cabin body 50, and the landing platform 10 is fixedly connected to the upper end of the cabin body 50 by bolts;

[0057] Preferably, the cabin body 50 includes a housing with an opening at the upper end and other unmanned cabin structures, such as an electronic control structure, an upper cover, etc. The cabin body 50 is a prior art;

[0058] Preferably, the landing platform 10 is a trough-shaped structure. The linear drive part 40 is located inside the landing platform 10, and the guiding assembly 20 and the centering assembly 30 are located outside the landing platform 10. The landing platform 10 covers the cabin body 50.
