The first drive member 42 is disposed in the accommodating cavity 17, connected to the first drive seat 41, and connected to the first gear 31. The first drive member 42 drives the first gear 31 to rotate, thereby driving the second gear 32 to drive the first transmission shaft 33 and the third gear 34 to rotate, thus driving the first traveling wheel 21 to rotate, and also drives the fourth gear 35 to drive the second transmission shaft 36 and the fifth gear 37 to rotate, thereby synchronously driving the second traveling wheel 22 to rotate.

[0034] The transmission assembly 3 is driven to rotate by a first driving element 42, thereby driving the first traveling wheel 21 and the second traveling wheel 22 to rotate. This reduces the number of first driving elements 42, thereby reducing the number of connecting lines of the first driving elements 42, which is beneficial for wiring.

[0035] In some embodiments, the first drive element 42 is a motor.

[0036] It is understood that in some embodiments, the transmission assembly 3 is not limited to the above structure. The transmission assembly 3 may also be other structures. For example, the transmission assembly 3 does not include the third gear 34 and the fifth gear 37. The first transmission shaft 33 is provided with a third tooth (not shown), and the second transmission shaft 36 is provided with a fourth tooth (not shown). The third tooth meshes with the first tooth 2111, and the fourth tooth meshes with the second tooth 2211.

[0037] It is understood that in some embodiments, the transmission assembly 3 is not limited to the above structure. The transmission assembly 3 may also be other structures. For example, the transmission assembly 3 does not include the second gear 32 and the fourth gear 35. The first transmission shaft 33 is provided with a fifth tooth (not shown), and the second transmission shaft 36 is provided with a sixth tooth (not shown).

[0038] It is understood that in some embodiments, the transmission assembly 3 is not limited to the above structure, and the transmission assembly 3 may also be other structures.

The first transmission shaft 33 is provided with a third tooth and a fifth tooth, and the second transmission shaft 36 is also provided with a fourth tooth and a sixth tooth. The fifth tooth and the sixth tooth are both meshed with the first gear 31, the third tooth is meshed with the first tooth 2111, and the fourth tooth is meshed with the second tooth 2211.

[0039] It is understood that, in some embodiments, please refer to Figure 9 The transmission assembly 3 and drive assembly 4 are not limited to the structures described above. They can be other structures, such as the transmission assembly 3 including a third gear 34 and a fifth gear 37, and the drive mechanism 100 including a second drive member 43 and a third drive member 44. Both the second drive member 43 and the third drive member 44 are disposed in the accommodating cavity 17. The second drive member 43 is connected to the third gear 34, which meshes with the first tooth portion 2111. The second drive member 43 drives the third gear 34 to rotate, thereby driving the first traveling wheel 21 to rotate. The third drive member 44 is connected to the fifth gear 37, which meshes with the second tooth portion 2211. The third drive member 44 drives the fifth gear 37 to rotate, thereby driving the second traveling wheel 22 to rotate.

[0041] In some embodiments, both the second driving element and the third driving element are motors.

[0042] In this embodiment, the drive mechanism 100 includes an arm 1, a walking assembly 2, a transmission assembly 3, and a drive assembly 4. The arm 1 is connected to the deformable mechanism 300 of the land-to-air vehicle 1000. The walking assembly 2 includes a first walking wheel 21 and a second walking wheel 22, which are rotatably mounted on the arm 1. The transmission assembly 3 is mounted on the arm 1 and connected to the first walking wheel 21 and the second walking wheel 22. The drive assembly 4 is mounted on the arm 1 and connected to the transmission assembly 3. The drive assembly 4 drives the transmission assembly 3 to rotate, thereby driving the first walking wheel 21 and the second walking wheel 22. Because the first walking wheel 21 and the second walking wheel 22 are rotatably connected to the arm 1, and the transmission assembly 3 and the drive assembly 4 are mounted on the arm 1, a single arm 1 can accommodate the first walking wheel 21, the second walking wheel 22, the transmission assembly 3, and the drive assembly 4, reducing the number of arms 1 and thus simplifying the structure of the drive mechanism 100.

[0043] This application also provides an embodiment of a land-air vehicle 1000; please refer to [link / reference]. Figure 10 and Figure 11 The air-to-ground aircraft 1000 includes a fuselage 200, a morphing mechanism 300, a propeller mechanism 400, and the aforementioned drive mechanism 100. The morphing mechanism 300 is disposed on the fuselage 200 and connected to the arm 1 of the drive mechanism 100. The propeller mechanism 400 is disposed on the drive mechanism 100. For the structure and function of the drive mechanism 100, please refer to the above embodiments, which will not be described in detail here.

[0044] The deformation mechanism 300 is used to drive the drive mechanism 100 to rotate and deform the propeller mechanism 400, so that the land-air vehicle 1000 switches between flight state and walking state. When the land-air vehicle 1000 is in flight state, the walking component 2 of the drive mechanism 100 is disengaged from the walking surface. When the land-air vehicle 1000 is in walking state, the walking component 2 of the drive mechanism 100 is in contact with the walking surface.

[0045] In some embodiments, the deformation mechanism 300 is connected to the connecting portion 112 of the arm 1 of the drive mechanism 100, and the connecting shaft of the deformation mechanism 300 is inserted into the rotating hole 111 of the arm 1 of the drive mechanism 100.

[0046] In some embodiments, the number of drive mechanisms 100 includes two, with one drive mechanism 100 located on one side of the fuselage 200 and the other drive mechanism 100 located on the other side of the fuselage 200. When the air-to-ground vehicle 1000 is in a walking state, the walking components 2 of the one drive mechanism 100 and the walking components 2 of the other drive mechanism 100 rotate at different speeds to achieve steering of the air-to-ground vehicle 1000.

[0047] In some embodiments, the land-air vehicle 1000 further includes a lighting assembly 500, which includes a first light 501 and a second light 502.
