Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Reference Figures 1 to 4 According to a first aspect of the present invention, a positioning wheel for positioning an aircraft includes a wheel body 100 and guide members 200. The wheel body 100 has a friction structure 110 on its peripheral wall surrounding its rotation axis. Two guide members 200 are provided, one at each end of the wheel body 100. The guide members 200 can rotate together with the wheel body 100, and their peripheral walls have guide surfaces 210 for guiding the aircraft to the friction structure 110. By providing the friction structure 110, the aircraft, in conjunction with the friction structure 110, can improve the driving effect, facilitating the adjustment of the aircraft's position along the rotation direction of the positioning wheel. Furthermore, by providing guide members 200 at both ends of the wheel body 100, each with a guide surface 210, the aircraft can be guided by the guide surface 210 when adjusting the wheel body 100, reducing lateral adjustment resistance and facilitating rapid adjustment of the aircraft onto the friction structure 110 of the wheel body 100, thereby improving the aircraft's adjustment efficiency.

[0034] Specifically, when the aircraft lands on the support platform 300, the positioning wheel drives the aircraft to adjust to a predetermined position. The wheel body 100 is a rotating structure, and a friction structure 110 to increase friction can be provided on the outer peripheral wall of the wheel body 100. The guide member 200 guides the aircraft to adjust to the friction structure 110. It can be understood that the rotation of the wheel body 100 drives the aircraft to move radially along the wheel body 100, while the aircraft also needs to move axially along the wheel body 100 to the friction structure 110. The aircraft can adjust by lateral movement during landing, or by other positioning and adjustment mechanisms. Therefore, by providing the guide member 200, the resistance when the aircraft moves axially along the wheel body 100 can be reduced, thereby efficiently positioning it to the friction structure 110. The friction structure 110 increases the static friction between itself and the aircraft, thereby reducing slippage and improving the driving effect. Through the above structure, the aircraft can be positioned efficiently, ultimately improving the adjustment efficiency of the aircraft.

[0035] It is conceivable that the wheel body 100 and the guide component 200 can be an integral structure.

[0036] Reference Figures 1 to 2 In some embodiments of this utility model, the guide surface 210 is a conical surface or an arc surface. Specifically, when the guide surface 210 is a conical surface, the conical surface can be inclined outward from the direction toward the wheel body 100. The conical surface can reduce the resistance when the aircraft moves along the axial direction of the positioning wheel, and the conical surface is also easy to manufacture and process.

[0037] In addition, the guide surface 210 can also be set as an arc surface. Similarly, the arc surface can gradually expand outward from the direction toward the wheel body 100, which can also reduce the resistance when the aircraft moves along the positioning wheel axis.

[0038] Reference Figures 1 to 2 In some embodiments of this invention, the edges of the guide member 200 and the wheel body 100 at their mating points are approximately flush. This allows for a smooth transition between the guide member 200 and the wheel body 100, reducing resistance when the aircraft moves along the axial direction of the positioning wheel.

[0039] Reference Figures 1 to 2 In some embodiments of this utility model, the friction structure 110 includes a plurality of first grooves 111 extending axially along the wheel body 100, and the first grooves 111 are spaced apart around the rotation axis.

[0040] With the above structure, the extension direction of the first groove 111 can not affect the axial movement of the aircraft along the positioning wheel, but can also improve the driving efficiency of the aircraft and the positioning wheel in the radial direction. Furthermore, the first groove 111 is easy to process and has a low manufacturing cost.

[0041] It is conceivable that the friction structure 110 may also have other embodiments. For example, the friction structure 110 may be set with other shaped patterns, such as herringbone patterns, wave patterns, etc., or the friction structure 110 may be made of a material that can improve friction, such as rubber.

[0042] Reference Figures 1 to 2 In some embodiments of this utility model, the guide member 200 is provided with a second groove 211 that can engage with the first groove 111. The second groove 211 may be disposed at the edge of the guide member 200 near the wheel body 100, and the second groove 211 may extend only to a portion of the guide member 200.

[0043] Reference Figures 1 to 2 In some embodiments of this utility model, the guide member 200 is detachably installed on the wheel body 100, and the guide member 200 is made of metal, while the wheel body 100 is made of elastic material. Specifically, the guide member 200 can be made of metal, which can reduce friction and allow the aircraft to slide with the guide member 200. The metal material can also improve wear resistance. The wheel body 100 can be made of elastic materials such as rubber or plastic, which can improve friction and driving effect. The guide member 200 can be provided with a boss structure for snap-fit ​​near the wheel body 100, and the corresponding side of the wheel body 100 can be provided with a groove corresponding to the boss. The boss can snap-fit ​​with the groove. Alternatively, the guide member 200 can be provided with a groove, and the wheel body 100 can be provided with a boss. Since the wheel body 100 is made of elastic material, the above-mentioned connection structure can be directly inserted with an interference fit, making disassembly and assembly relatively convenient.

[0044] It is conceivable that the guide component 200 can also be connected to the wheel body 100 by fasteners.

[0045] Reference Figures 3 to 6 According to a second aspect embodiment of the present invention, the support platform 300 includes a positioning wheel for positioning an aircraft as described above. The support platform 300 can be used to support an aircraft. By employing the positioning wheel for positioning an aircraft as described above on the support platform 300, aircraft adjustment can be facilitated, and positioning efficiency can be improved.

[0046] Reference Figures 3 to 6In some embodiments of this utility model, the system further includes a platform body 310 and a first driving device 320. The platform body 310 is provided with a positioning mechanism and multiple positioning wheels. Each positioning wheel is spaced apart on the platform body 310 along the Y-axis direction. Each positioning wheel is connected to the first driving device 320. The first driving device 320 can drive the positioning wheels to rotate. The positioning mechanism can drive the aircraft to move along the X-axis direction and position it on the positioning wheel. The positioning wheel can drive the aircraft to move along the Y-axis direction and position it. Specifically, the carrying platform 300 can be mounted on a vehicle, and the aircraft can land on the carrying platform 300 and take off from the carrying platform 300. It is understood that the bottom of the aircraft has a support member 400, which can be configured as a support crossbar 410. The first drive unit 320 can be configured as a drive motor and a chain drive structure. Each positioning wheel is connected to the drive motor via the chain drive structure. The positioning wheels are spaced apart along the Y-axis and can drive the aircraft along the Y-axis. The positioning mechanism, on the other hand, can drive the aircraft to move and position itself along the X-axis, thus achieving planar positioning of the aircraft. In actual operation, the aircraft first lands on the support platform 300. The positioning mechanism then causes the aircraft to move along the X-axis. During this movement, the support crossbar 410 engages with the guide surface 210 of the guide member 200, facilitating X-axis positioning of the aircraft. After positioning, the support crossbar 410 moves onto the friction structure 110 of the wheel body 100. Then, the first drive unit 320 drives each positioning wheel to rotate. The positioning wheels, through the friction structure 110, drive the support crossbar 410 to move along the Y-axis, achieving positioning in the Y-axis direction. This structure improves the positioning efficiency of the aircraft.

[0047] Reference Figures 3 to 6 In some embodiments of this utility model, the positioning mechanism includes a second driving device 311 and a limiting member 312. The limiting member 312 is disposed on the platform body 310. The second driving device 311 can drive the platform body 310 to extend to an unfolded state and retract to a retracted state along the X-axis direction. When the second driving device 311 drives the platform body 310 to switch to the retracted state, the limiting member 312 can abut against the aircraft and drive the aircraft to be positioned in the X-axis direction. In the unfolded state, the platform body 310 can expand its bearing area to facilitate the landing of the aircraft, while in the retracted state, the aircraft can be positioned and retracted.

[0048] Specifically, the platform body 310 may include a base 313, a first platform frame 314, and a second platform frame 315. The first platform frame 314 and the second platform frame 315 are disposed opposite each other on the top of the base 313, and the first platform frame 314 and the second platform frame 315 can be slidably connected along the X-axis. The first drive device 320 is drively connected to the first platform frame 314 and / or the second platform frame 315. Specifically, the first platform frame 314 and the second platform frame 315 are disposed opposite each other along the X-axis. The first platform frame 314 and the second platform frame 315 can be connected by a slide rail, which can be disposed on the base 313, so that the first platform frame 314 and the second platform frame 315 can move closer to each other and slide away from each other to achieve extension and retraction. The limiting member 312 can abut and position itself against the aircraft during the retraction of the platform body 310, thereby achieving the positioning of the aircraft in the X-axis direction.

[0049] It is conceivable that the first drive device 320 can be configured as an electric or hydraulic push rod. The first drive device 320 can be fixed on the base 313, and its output end can be connected to the first platform frame 314 and the second platform frame 315 respectively, thereby driving the first platform frame 314 and the second platform frame 315 to slide. Alternatively, the first drive device 320 can be disposed on the first platform frame 314 or the second platform frame 315, and its output end can be on the platform frame respectively.

[0050] The vehicle according to a third aspect embodiment of the present invention includes a vehicle employing the aforementioned carrier platform 300. By employing the carrier platform 300, the vehicle can receive and release aircraft via the carrier platform 300, and the carrier platform 300 facilitates the adjustment of the aircraft's position, thereby improving the aircraft's positioning efficiency.
