[0029] This utility model provides a transfer trolley for vertical take-off and landing aircraft. The transfer trolley has a simple structure and high versatility.

[0030] like Figures 1 to 5 As shown, the vertical takeoff and landing (VTOL) aircraft transport trolley provided in this embodiment includes a tow bar 10, a trolley body 20, a lifting mechanism 30, and a connecting seat 40. There are at least two trolley bodies 20, each connected to the tow bar 10. The connecting seat 40 is used to fix the landing gear of the VTOL aircraft. The connecting seat 40 is located below the trolley body 20 and is connected to the trolley body 20 via the lifting mechanism 30. The lifting mechanism 30 adjusts the ground clearance of the connecting seat 40.

[0031] When transporting a vertical takeoff and landing (VTOL) aircraft using the VTOL transport trolley provided in this embodiment, a trolley body 20 can be mounted across each landing gear of the VTOL aircraft. The landing gear is then fixed to the connecting seat 40; the connecting seat 40 is then connected to the lifting mechanism 30, and the height of the connecting seat 40 is adjusted via the lifting mechanism 30; finally, the tow rod 10 is connected to the two trolley bodies 20, thus completing the assembly. The VTOL aircraft can be transported by pulling the tow rod 10 using the transport vehicle.

[0032] In this embodiment, due to the connecting seat 40, the entire weight of the VTOL aircraft can be supported by the landing gear, and the landing gear's ground clearance can be adjusted by the lifting mechanism 30. During transport, the vehicle body 20 can move using its wheels. Since the ground clearance is adjustable, collisions between the landing gear and ground obstacles can be prevented. Furthermore, because the height of the connecting seat 40 is adjustable, it can adapt to various VTOL aircraft.

[0033] Therefore, this embodiment can complete the transfer of a vertical takeoff and landing (VTOL) aircraft by setting up the tow bar 10, the trolley body 20, the lifting mechanism 30, and the connecting seat 40. The VTOL aircraft transfer trolley has a simple structure and high versatility.

[0034] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the main body 20 of the vehicle includes a frame 21, a wheel fixing plate 22, and a lifting mechanism fixing plate 23. Both the wheel fixing plate 22 and the lifting mechanism fixing plate 23 are mounted on the frame 21. The wheels are connected to the wheel fixing plate 22 via connecting rods 24.

[0035] In this embodiment, the connecting rod 24 can be connected to the wheel fixing plate 22 by bolts or other fixing structures, so as to select the appropriate wheel according to the terrain.

[0036] The connecting seat 40 is connected to the frame 21 in sequence through the lifting mechanism 30 and the lifting mechanism fixing plate 23, so as to fix the connecting seat 40 to the bottom of the frame 21.

[0037] A traction joint 25 is also provided on the frame 21 for fixing the traction rod 10.

[0038] Please continue to refer to Figure 3 and Figure 5 In this embodiment, the lifting mechanism 30 includes a worm gear 31, a worm 32, and a handle 33. The worm gear 31 is fixed to the lifting mechanism fixing plate 23. The worm 32 extends into the worm gear 31 and is connected to the connecting seat 40 below. The handle 33 is connected to the worm gear 31 to control the rotation of the worm gear 31. Through the cooperation of the worm gear 31 and the worm 32, the worm 32 can move up and down relative to the worm gear 31 along its own axis to change the height of the connecting seat 40 above the ground.

[0039] The connecting seat 40 includes a base 41, a cover plate 42, and a connecting portion 43. A groove 411 adapted to the shape of the landing gear support rod is formed on the base 41. The cover plate 42 covers the groove 411. When the landing gear support rod is placed in the groove 411, the cover plate 42 covers the groove 411 to secure the landing gear support rod.

[0040] The connecting part 43 is disposed on either the base 41 or the cover plate 42; in this embodiment, it is disposed on the base 41. The connecting part 43 can be connected to the worm gear 32 via a connecting structure, such as a bolt. The connecting part 43 is disposed in the middle of the base 41 to ensure the balance of the connecting seat 40.

[0041] In this embodiment, a connecting seat 40 is provided at both the front and rear ends of the vehicle body 20, and each connecting seat 40 is connected to the frame 21 through a corresponding lifting mechanism 30. In other words, the landing gear on each side of the vertical take-off and landing aircraft can be supported by two connecting seats 40 to ensure the stability of the vertical take-off and landing aircraft during transportation.

[0042] When transporting a vertical takeoff and landing (VTOL) aircraft according to the above structure, the trolley body 20 can first be straddled on both sides of the landing gear; then, the VTOL aircraft can be slightly lifted by the wings so that the base 41 of the connecting seat 40 can be inserted between the support rod of the landing gear and the ground, and the support rod can be placed in the groove of the connecting seat 40; then, the cover plate 42 can be placed on the groove and connected to the lifting mechanism 30 through the connecting part 43; then, the VTOL aircraft can be lifted to the set height by the lifting mechanism 30; finally, the tow bar 10 can be connected to the trolley body 20, and the VTOL aircraft can be transported by the transport vehicle.

[0043] This embodiment utilizes a tow bar 10, a trolley body 20, a lifting mechanism 30, and a connecting seat 40 to complete the transfer of a vertical takeoff and landing (VTOL) aircraft. This VTOL aircraft transfer trolley has a simple structure and high versatility.
