By adjusting their modes, amphibious aircraft can perform flight missions in the air and walk on the ground.

[0003] However, in implementing the embodiments of this application, the inventors discovered that currently, when switching between flight mode and walking mode, the walking mechanism of the land-to-air aircraft needs to be manually operated to drive the propeller mechanism, thereby achieving mode switching. However, achieving mode switching through manual operation results in a low degree of automation for the aircraft, limiting its operational range and environmental adaptability.

[0004] Application content The main technical problem addressed in this application is to provide a deformation mechanism and a land-to-air aircraft, aiming to solve the technical problem that the low level of automation of the aircraft, which is caused by manually turning it to achieve mode switching, and thus limits the operating range and environmental adaptability of the land-to-air aircraft.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a deformable mechanism, including a support, a motion component, a linkage assembly, and a drive assembly. The support is used to be mounted on the fuselage of a land-to-air vehicle and to be rotatably connected to the vehicle's walking mechanism. The motion component is movably connected to the support, the linkage assembly is movably connected to the motion component and to be movably connected to the walking mechanism, and the drive assembly is connected to the support and the motion component. The drive assembly is used to drive the motion component to move, thereby driving the linkage assembly to move, and thus driving the walking mechanism to rotate, so that the walking mechanism contacts or disengages from the walking surface, thereby causing the walking mechanism to fold or unfold.

[0006] Optionally, the motion component includes a first screw and a first motion sleeve. The first screw extends along a first direction, which is perpendicular to the rotation axis of the walking mechanism. The first screw is rotatably connected to the bracket and connected to the drive component. The first motion sleeve is fitted onto the first screw and is movably connected to the linkage assembly.

[0007] Optionally, the linkage assembly includes a first link, which is movably connected to the first motion sleeve, and the first link is movably connected to the walking mechanism.

[0009] Optionally, the motion component includes a second screw and a second motion sleeve. The second screw extends along a second direction, which is perpendicular to the rotation axis of the walking mechanism. The second screw is rotatably connected to the bracket and connected to the drive component. The second motion sleeve is fitted onto the second screw and is rotatably connected to the linkage assembly.

[0010] Optionally, the linkage assembly includes a second linkage, which is rotatably connected to the second motion sleeve, and the second linkage is used for movably connecting to the walking mechanism.

[0013] Optionally, the drive assembly further includes a first gear and a second gear, the first gear being connected to the drive member and the second gear being connected to the motion assembly, the second gear meshing with the first gear.

[0014] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a land-air aircraft, including a fuselage, a running gear, a propeller mechanism and the above-mentioned morphing mechanism, wherein the support of the morphing mechanism is disposed on the fuselage, the linkage assembly of the morphing mechanism is movably connected to the running gear, and the propeller mechanism is disposed on the running gear.

[0015] In this embodiment, the deformable mechanism includes a support, a motion component, a linkage assembly, and a drive assembly. The support is mounted on the fuselage of the air-to-ground vehicle and rotatably connected to the vehicle's locomotive mechanism. The motion component is rotatably connected to the support, and the linkage assembly is rotatably connected to the motion component and rotatably connected to the locomotive mechanism. The drive assembly is connected to the support and the motion component, and drives the motion component to move, thereby driving the linkage assembly to move, which in turn drives the locomotive mechanism to rotate the propeller mechanism of the air-to-ground vehicle. This causes the locomotive mechanism to contact or disengage from the locomotive surface, and also causes the propeller mechanism to fold or unfold. By using the drive assembly to drive the motion component to move, which in turn drives the linkage assembly to move, and thus drives the locomotive mechanism to rotate, causing the locomotive mechanism to contact or disengage from the locomotive surface, and thus folding or unfolding the locomotive mechanism, the air-to-ground vehicle can automatically switch between flight mode and locomotive mode, improving its operational range and environmental adaptability.

[0021] This application provides a deformation mechanism 100, please refer to [link / reference]. Figure 1The deformation mechanism 100 includes a support 1, a third connecting shaft 2, a motion component 3, a linkage assembly 4, and a drive assembly 5. The support 1 is mounted on the fuselage 200 of the land-to-air vehicle 1000. The third connecting shaft 2 passes through the walking mechanism 300 and the support 1, allowing the support 1 to be rotatably connected to the walking mechanism 300 of the land-to-air vehicle 1000. The motion component 3 is movably connected to the support 1. The linkage assembly 4 is movably connected to the motion component 3 and is also movably connected to the walking mechanism 300. The drive assembly 5 is connected to the support 1 and the motion component 3, and drives the motion component 3 to move, which in turn drives the linkage assembly 4, thereby driving the walking mechanism 300 to rotate. This causes the walking mechanism 300 to contact or disengage from the walking surface, allowing it to fold or unfold, thus enabling the land-to-air vehicle 1000 to switch between walking mode and flight mode.

[0022] For the aforementioned bracket 1, please refer to Figure 2 The bracket 1 is provided with a mounting groove 11, a first rotating hole 12, a second rotating hole 13, a third rotating hole 14, and a movement port 15. The mounting groove 11 connects the first rotating hole 12, the second rotating hole 13, the third rotating hole 14, and the movement port 15. The first rotating hole 12, the mounting groove 11, and the second rotating hole 13 are arranged sequentially along the first direction z, that is, the first rotating hole 12 and the second rotating hole 13 are arranged opposite each other along the mounting groove 11. The first direction z is perpendicular to the rotation axis of the traveling mechanism 300.

[0023] Furthermore, the bracket 1 is provided with multiple first hollow openings 16, which are used to reduce weight.

[0024] For the third connecting shaft 2 mentioned above, please refer to Figure 1 The third connecting shaft 2 passes through the third rotating hole 14 and the fourth rotating hole 301 of the traveling mechanism 300 (e.g., Figure 10 As shown), the walking mechanism 300 rotates around the third connecting shaft 2, that is, the axis of the third connecting shaft 2 is the rotation axis of the walking mechanism 300.

[0025] For motion component 3 mentioned above, please refer to Figure 3 The motion component 3 includes a first screw 31 and a first motion sleeve 32. The first screw 31 is rotatably disposed in the mounting groove 11 and passes through the first rotating hole 12 and the second rotating hole 13. The first screw 31 extends along the first direction z, so that the first screw 31 is rotatably connected to the bracket 1 and the first screw 31 is connected to the drive component 5. The first motion sleeve 32 is disposed in the mounting groove 11 and is sleeved on the first screw 31. The first motion sleeve 32 is threadedly connected to the first screw 31, so that the first motion sleeve 32 moves along the first direction z under the rotation of the first screw 31. The first motion sleeve 32 is movably connected to the connecting rod component 4.

[0026] Furthermore, the first moving sleeve 32 is provided with a first mounting hole 321 and a second hollow opening 322. The first mounting hole 321 is connected to the mounting groove 11.

[0027] For the aforementioned link assembly 4, please refer to Figure 4 The linkage assembly 4 includes a first connecting rod 41, a first connecting shaft 42, and a second connecting shaft 43. One side of the first connecting rod 41 is disposed in the mounting groove 11, and the other side of the first connecting rod 41 extends out of the mounting groove 11 from the motion port 15. The first connecting rod 41 is provided with a second mounting hole 411 and a third mounting hole 412. The first connecting shaft 42 passes through the first mounting hole 411 and the second mounting hole 411, so that the first connecting rod 41 is movably connected to the first motion sleeve 32. The second connecting shaft 43 passes through the third mounting hole 412 and the traveling mechanism 300, so that the first connecting rod 41 is movably connected to the traveling mechanism 300.

[0028] Driven by the drive assembly 5, the first screw 31 rotates to drive the first moving sleeve 32 to move along the first direction z, thereby driving the first connecting rod 41 to move, which in turn drives the walking mechanism 300 to rotate, causing the walking mechanism 300 to contact or detach from the walking surface, and thus causing the walking mechanism 300 to fold or unfold.

[0029] In some embodiments, the number of the third rotating hole 14, the third connecting shaft 2, the motion port 15, the first mounting hole 321, and the connecting rod assembly 4 all include two. Specifically, the two third rotating holes 14, the two motion ports 15, and the two first mounting holes 321 are all arranged opposite each other along the second direction y. The second direction y, the first direction z, and the rotation axis of the traveling mechanism 300 are perpendicular to each other. A third connecting shaft 2 passes through a first rotating hole 12 and a fourth rotating hole 301 of the traveling mechanism 300 (e.g., ...). Figure 10 As shown), another third connecting shaft 2 passes through another first rotating hole 12 and another fourth rotating hole 301 of the walking mechanism 300. The first connecting rod 41 of the connecting rod assembly 4 is movably disposed in a first mounting hole 321 and a fourth mounting hole 302 of the walking mechanism 300. The first connecting rod 41 of the other connecting rod assembly 4 is rotatably disposed in another first mounting hole 321 and another fourth mounting hole 302 of the walking mechanism 300.

[0030] For the aforementioned driver component 5, please refer to Figure 5 The drive assembly 5 includes a drive base 51 and a drive member 52. The drive base 51 is connected to the bracket 1. The drive member 52 is connected to the drive base 51 and the first screw 31, and the drive member 52 is used to drive the first screw 31 to rotate.

[0031] In some embodiments, the drive element 52 is a motor.

[0032] Furthermore, the drive assembly 5 also includes a first gear 53 and a second gear 54. The first gear 53 is connected to the drive member 52, and the second gear 54 is connected to the first screw 31. The second gear 54 meshes with the first gear 53. The first gear 53 and the second gear 54 are arranged along the rotation axis x of the traveling mechanism 300, such that the drive member 52 and the first screw 31 are arranged along the rotation axis x. The drive member 52 drives the first gear 53 to rotate, thereby driving the second gear 54 to rotate the first screw 31.

[0033] It is understood that, in some embodiments, please refer to Figure 6 The motion assembly 3 and the linkage assembly 4 are not limited to the structures described above. They can also have other structures. For example, the motion assembly 3 includes a second screw 33 and a second motion sleeve 34, and the linkage assembly 4 includes a second connecting rod 44, a first connecting shaft 42, and a second connecting shaft 43. The second screw 33 is rotatably connected to the bracket 1, extends along a second direction y, and is connected to the second gear 54. The second motion sleeve 34 is fitted onto the second screw 33 and is threadedly connected to it. The first connecting shaft 42 passes through the second motion sleeve 34 and the second connecting rod 44, allowing the second connecting rod 44 and the second motion sleeve 34 to be movably connected. The second connecting shaft 43 passes through the second connecting rod 44 and the traveling mechanism 300, allowing the second connecting rod 44 to be movably connected to the traveling mechanism 300. The driving component 52 drives the first gear 53 to rotate the second gear 54, thereby driving the second screw 33 to rotate, which in turn drives the second moving sleeve 34 to move along the second direction y, thereby driving the second connecting rod 44 to move.

[0034] In some embodiments, the number of linkage assemblies 4 and motion assemblies 3 each includes two. The two linkage assemblies 4 are arranged opposite each other along the second direction y, and the two motion assemblies 3 are also arranged opposite each other along the second direction y. The second link 44 of one linkage assembly 4 is movably connected to the second motion sleeve 34 of one motion assembly 3 and a traveling mechanism 300, and the second link 44 of the other linkage assembly 4 is movably connected to the second motion sleeve 34 of another motion assembly 3 and another traveling mechanism 300. The driving member 52 drives the first gear 53 to rotate, thereby driving the second screws 33 of the two motion assemblies 3 to rotate, thus driving the second motion sleeves 34 of the two motion assemblies 3 to move towards or away from each other along the second direction y.

[0035] In this embodiment, the deformable mechanism 100 includes a support 1, a motion component 3, a linkage assembly 4, and a drive assembly 5. The support 1 is mounted on the fuselage 200 of the air-to-ground vehicle 1000 and is rotatably connected to the walking mechanism 300 of the air-to-ground vehicle 1000. The motion component 3 is movably connected to the support 1. The linkage assembly 4 is movably connected to the motion component 3 and is movably connected to the walking mechanism 300. The drive assembly 5 is connected to the support 1 and the motion component 3. The drive assembly 5 is used to drive the motion component 3 to move, thereby driving the linkage assembly 4 to move, which in turn drives the walking mechanism 300 to rotate the propeller mechanism 400 of the air-to-ground vehicle 1000, causing the walking mechanism 300 to contact or detach from the walking surface, and causing the propeller mechanism 400 to fold or unfold. The drive component 5 drives the motion component 3 to move, which in turn drives the linkage component 4 to move, thereby driving the walking mechanism 300 to rotate. This causes the walking mechanism 300 to contact or detach from the walking surface, and then causes the walking mechanism 300 to fold or unfold. This enables the land-air vehicle 1000 to automatically switch between flight mode and walking mode, improving the operating range and environmental adaptability of the land-air vehicle 1000.

[0036] This application also provides an embodiment of a land-air vehicle 1000; please refer to [link / reference]. Figures 7-10 The land-air vehicle 1000 includes a fuselage 200, a walking mechanism 300, a propeller mechanism 400, and the aforementioned morphing mechanism 100. The support 1 of the morphing mechanism 100 is disposed on the fuselage 200, and the linkage assembly 4 of the morphing mechanism 100 is movably connected to the walking mechanism 300. The propeller mechanism 400 is disposed on the walking mechanism 300. For the structure and function of the morphing mechanism 100, please refer to the above embodiments, which will not be described in detail here.

[0037] The deformation mechanism 100 is used to drive the walking mechanism 300 to rotate and deform, so that the walking mechanism 300 contacts or separates from the walking surface, thereby causing the walking mechanism 300 to fold or unfold, thus enabling the land-air vehicle 1000 to switch between walking mode and flight mode.

[0038] Furthermore, the body 200 is provided with a receiving cavity 201 and a first opening 202, the receiving cavity 201 communicating with the first opening 202, and the bracket 1 of the deformation mechanism 100 passing through the receiving cavity 201 and the first opening 202. Since the driving member 52 of the driving assembly 5 of the deformation mechanism 100 and the first screw 31 of the motion assembly 3 are arranged along the rotation axis in the direction x, the space occupied by the deformation mechanism 100 in the receiving cavity 201 along the first direction z is reduced.

[0039] In some embodiments, the number of first openings 202 includes two, with one first opening 202, the accommodating cavity 201 and the other first opening 202 connected in sequence, that is, one first opening 202, the accommodating cavity 201 and the other first opening 202 are arranged in sequence along the second direction y.

[0040] In some embodiments, the number of walking mechanisms 300 includes two, with one walking mechanism 300, the body 200 and the other walking mechanism 300 arranged along the second direction y, that is, the body 200 is located between the two walking mechanisms 300.
