[0047] In related technologies, amphibious vehicles combine the dual capabilities of cars and boats, allowing them to travel on land like a car and float on water like a boat. Due to their superior amphibious capabilities, they can cross rivers, lakes, and seas without being restricted by bridges or boats, thus holding special historical significance in transportation. Some related technologies integrate propellers and motors onto the wheels to achieve both land and water travel, but this results in a loose wheel structure and a larger overall size.

[0048] In this embodiment, the wheel 100 includes a tire assembly 10, a drive assembly 30, and a propeller assembly 40. The drive assembly 30 includes a first drive member 31 and a second drive member 32. The first drive member 31 is connected to the tire assembly 10 and drives the tire assembly 10 to rotate. The second drive member 32 is connected to the propeller assembly 40 and drives the propeller assembly 40 to rotate. The first drive member 31 and the second drive member 32 are spaced apart along the axial direction of the wheel 100, and the projections of the first drive member 31 and the second drive member 32 along the radial direction of the wheel 100 at least partially overlap. Thus, by arranging the drive motor of the tire assembly 10 near the rim and the drive motor of the propeller on the central axis of the tire assembly 10, the wheel 100 has a compact design, reducing the axial space of the wheel 100 and providing greater water flow space for water travel, increasing water flowability and improving propulsion efficiency.

[0049] In this application, the specific location and form of the wheel 100 are not limited to meet different needs. In one embodiment, the wheel 100 may be located at the spare tire position of the vehicle 300, and the following description will use the wheel 100 as a spare tire.

[0050] Please see Figures 1 to 7 In a first aspect, the present invention provides a wheel 100, comprising: a tire assembly 10, a drive assembly 30, and a propeller assembly 40. The drive assembly 30 includes a first drive member 31 and a second drive member 32. The first drive member 31 is connected to the tire assembly 10 and drives the tire assembly 10 to rotate. The second drive member 32 is connected to the propeller assembly 40 and drives the propeller assembly 40 to rotate. The first drive member 31 and the second drive member 32 are spaced apart along the axial direction of the wheel 100, and the projections of the first drive member 31 and the second drive member 32 along the radial direction of the wheel 100 at least partially overlap.

[0051] In the wheel of this embodiment, the wheel 100 includes a tire assembly 10, a drive assembly 30, and a propeller assembly 40. The drive assembly 30 includes a first drive member 31 and a second drive member 32. The first drive member 31 is connected to the tire assembly 10 and drives the tire assembly 10 to rotate. The second drive member 32 is connected to the propeller assembly 40 and drives the propeller assembly 40 to rotate. The first drive member 31 and the second drive member 32 are spaced apart along the axial direction of the wheel 100, and the projections of the first drive member 31 and the second drive member 32 along the radial direction of the wheel 100 at least partially overlap. Thus, by integrating the first drive member 31 and the second drive member 32 inside the tire assembly 10, space utilization is higher without increasing the volume of the wheel 100. This allows for a compact design structure for the wheel 100, reduces the axial space of the wheel 100, provides greater water flow space for water travel, increases water flow permeability, improves propulsion efficiency, and enhances the functionality of the vehicle 300 without changing its original form.

[0052] In this application embodiment, the specific type of vehicle 300 is not limited. Vehicle 300 can be a gasoline vehicle, an electric vehicle, or a hybrid vehicle; and the specific model of vehicle 300 is not limited either. For example, vehicle 300 can be an off-road vehicle.

[0053] Optionally, the drive assembly 30 is located radially inside the tire assembly 10.

[0054] The vehicle 300 of this embodiment, capable of both land and water travel, integrates the drive assembly 30 radially inside the tire assembly 10. This avoids the need for an additional underwater thruster that would cause a protruding part of the vehicle 300, affecting its overall appearance. An underwater thruster reduces the vehicle 300's ground clearance, hindering its normal road travel and posing a risk of damage from collisions. Furthermore, it avoids the limitation of an underwater thruster being solely for water travel, which is functionally unsustainable and cost-effective.

[0055] The vehicle 300 of this embodiment cleverly utilizes the space of the spare tire, a space rarely used in land-based driving structures. The spare tire integrates a drive motor and propeller, enabling independent drive for both the spare tire and the propeller. The vehicle 300 of this embodiment also adds water-based driving capability by concealing the underwater propulsion device without affecting the overall vehicle appearance. This not only does not affect the normal land-based driving of the vehicle 300 but also provides auxiliary drive, enhancing its land-based driving function.

[0056] Optionally, the wheel 100 also includes a center axle support 20, the tire assembly 10 includes a hub 11 and a tire 12, the tire 12 is mounted on the outer periphery of the rim of the hub 11, and the center axle support 20 is coaxially arranged with the hub 11 and is at least partially located on the inner side of the hub 11.

[0057] Optionally, the first driving component 31 includes a first stator 311 and a first rotor 312. The first stator 311 is connected to the central shaft support 20 through a first stator bracket, and the first rotor 312 is connected to the wheel rim. The first rotor 312 rotates under the action of the first stator 311 to drive the tire 12 to rotate.

[0058] Optionally, the second drive unit 32 includes a second stator 321 and a second rotor 322. The second stator 321 is disposed on the central shaft support 20, and the second rotor 322 is connected to the propeller assembly 40. The second rotor 322 rotates under the action of the second stator 321 to drive the propeller assembly 40 to rotate.

[0059] Optionally, in the radial direction of the tire assembly 10, the second drive member 32 is located on the side of the first drive member 31 opposite to the tire 12.

[0060] In the axial direction of the tire assembly 10, the second drive member 32 is located on one side of the central axle support 20.

[0061] Optionally, the propeller assembly 40 includes a first propeller 41, which is rotatably mounted on the central shaft support 20 and connected to a rim. The first rotor 312 of the first drive member 31 drives the first propeller 41 to rotate through the rim.

[0062] Optionally, in the axial direction of the tire assembly 10, the first propeller 41 is spaced apart from the first drive member 31.

[0063] Optionally, the first propeller 41 and the spokes of the hub 11 have the same structure.

[0064] Optionally, the propeller assembly 40 includes a second propeller 42, which is rotatably mounted on the central shaft support 20. The second rotor 322 of the second drive member 32 is connected to the second propeller 42 and drives the second propeller 42 to rotate.

[0065] Optionally, in the axial direction of the tire assembly 10, the second propeller 42 is spaced apart from the second drive member 32.

[0066] In this embodiment, the drive motor and propeller are integrated into the spare tire, and the spare tire and propeller are driven independently by different drive motors. The spare tire's drive motor is located near the rim and uses radial magnetic flux, while the propeller's drive motor is located on the spare tire's central shaft support 20 and uses axial magnetic flux. This design results in a compact structure, reduces motor size, provides more space for water flow during water travel, increases water flowability, and improves propulsion efficiency.

[0067] Optionally, the second drive unit 32 is disposed between the central shaft support 20 and the second propeller 42.

[0068] This design features a compact structure and reduces the size of the motor, providing more space for water flow when traveling on water, increasing water flowability and improving propulsion efficiency.

[0069] Optionally, the first propeller 41 rotates in the opposite direction to the second propeller 42.

[0070] This embodiment integrates two propellers. One is a propeller-shaped spoke connected to the wheel hub and driven by the spare tire's drive motor. It not only acts as propeller blades to generate thrust in the water but also supports the wheel rim, enhancing the spare tire's strength. The other is a normal propeller blade connected to the spare tire's central shaft via bearings, independent of the spare tire, and driven by the propeller's drive motor. The two propellers rotate in opposite directions (one is a left-handed propeller, the other a right-handed propeller), ensuring sufficient thrust for water travel while eliminating roll torque, thus enabling smooth vehicle movement.

[0071] Secondly, a wheel system 200 is also provided, which includes a wheel 100 and a tipping assembly 210 according to any of the above embodiments.

[0072] Optionally, the flipping assembly 210 is adapted to be connected to the vehicle body 310. The flipping assembly 210 includes a third drive member 211 and a flipping rod 212. The third drive member 211 is connected to the flipping rod 212, and the flipping rod 212 is connected to the wheel 100. The third drive member 211 drives the flipping rod 212 to rotate so as to flip the wheel 100.

[0073] Optionally, the flip assembly 210 also includes a mounting bracket 213, which is fixed to the vehicle body 310, and a third drive component 211 is disposed on the mounting bracket 213.

[0074] Optionally, there are two mounting brackets 213, which are spaced apart along the width of the vehicle body 310, and the flip bar 212 is disposed between the two mounting brackets 213.

[0075] Optionally, the wheel system 200 also includes a steering assembly 220, one end of which is connected to the tilting assembly 210 and the other end of which is connected to the wheel 100. The steering assembly 220 is capable of changing the orientation of the wheel 100.

[0076] Optionally, the steering assembly 220 includes a fourth drive member 221 and a swing arm 222. The fourth drive member 221 is fixed to the tilting rod 212, one end of the swing arm 222 is connected to the fourth drive member 221, and the other end of the swing arm 222 is connected to the central shaft bracket 20.

[0077] Optionally, the swing arm 222 includes a first side arm and a second side arm, the wheel 100 is disposed between the first side arm and the second side arm, and both the first side arm and the second side arm are connected to the central axle bracket 20.

[0078] Optionally, the fourth drive unit 221 is fixed at the middle position of the flip rod 212.

[0079] In this embodiment, during normal land driving, the wheel system 200 can rotate around the flipping rod 212 at a certain angle via the flipping component 210. In water driving mode, the water propulsion angle can be adjusted according to the water surface conditions. The angle between the propulsion system and the horizontal plane is controlled by the flipping component 210, thereby adjusting the vehicle 300's posture on water, solving the problem of the front of the vehicle sinking due to the imbalance of weight between the front and rear of the vehicle 300, reducing driving resistance, and balancing the impact of the unstable water surface during water driving. In land driving mode, when not in use, the wheel system 200 is flush with the tailgate, which does not affect the overall appearance of the vehicle or its normal land driving. In special circumstances, the multi-functional spare tire can be flipped to contact the ground, such as assisting the vehicle in getting out of trouble in complex terrain during off-road driving, assisting driving or driving to ensure the normal and stable driving of the vehicle 300 in the event of a tire blowout, and assisting in rapid braking through energy recovery.

[0080] The steering component 220 of this application can adjust the orientation of the multi-functional spare tire. Combined with the flipping component 210, it can achieve efficient steering when driving on water, as well as enhance steering and parallel parking functions when driving on land.

[0081] Thirdly, a vehicle 300 is also provided, which includes wheels 100 of any of the preceding embodiments; and / or wheel systems 200 of any of the preceding embodiments.

[0082] Optionally, the vehicle 300 also includes a body 310, with the wheel system 200 located on the outside of the trunk of the body 310.

[0083] In summary, compared with the prior art, the wheel 100, wheel system 200 and vehicle 300 of the embodiments of this application not only realize the water driving function of the vehicle 300 without increasing the design space or affecting the land driving function of the vehicle 300, but also enhance the normal land driving function of the vehicle 300. They have the advantages of compact space design, high integration of functions and diverse uses.

[0084] In the wheel 100, wheel system 200, and vehicle 300 of this application embodiment, the wheel 100 includes a tire assembly 10, a central axle support 20, a drive assembly 30, and a propeller assembly 40. At least a portion of the propeller assembly 40 is disposed on the tire assembly 10. The drive assembly 30 is adapted to drive the tire assembly 10 to rotate relative to the central axle support 20 and to drive at least a portion of the propeller assembly 40 to rotate. Thus, by combining the drive assembly 30 and the propeller assembly 40, the spare tire position of the vehicle 300 can be used for water propulsion, enabling the vehicle 300 to travel on both land and water simultaneously. By modifying the spare tire position, which is not normally used, the functionality of the vehicle 300 is improved without changing its original form.

[0085] Specifically, at least a portion of the propeller assembly 40 is disposed on the tire assembly 10, and the helical center of the propeller assembly 40 coincides with the center of the tire assembly 10, so that the propeller assembly 40 can rotate together with the tire assembly 10 around the center.

[0086] Meanwhile, the central support 20 can be at least partially inserted through the rotation center of the tire assembly 10 and the propeller assembly 40, allowing the tire assembly 10 and the propeller assembly 40 to rotate relative to the central support 20. The drive assembly 30 can provide power for the rotation of the tire assembly 10 and the propeller assembly 40.

[0087] In this way, the drive assembly 30 drives the propeller assembly 40 to rotate together with the tire assembly 10, so that the wheel 100 in the spare tire position can be used in both water and land environments at the same time, enabling the vehicle 300 to travel on both water and land.

[0088] It should be noted that the propeller assembly 40 can also at least partially replace the spokes on the hub 11, so that at least part of the propeller assembly 40 exists as part of the tire assembly 10, further improving the integration of the water driving structure and the land driving structure and saving design space.

[0089] Of course, in some embodiments, the wheels 100 in other positions of the vehicle 300 can also be modified, such as the other four wheels 100 of the vehicle 300. The embodiments of this application do not limit the specific wheels 100 to be modified or the number thereof, in order to meet various needs.

[0090] In some embodiments, the propeller assembly 40 includes a first propeller 41 and a second propeller 42, the first propeller 41 being disposed on the tire assembly 10 and the second propeller 42 being disposed on the central shaft support 20, and the drive assembly 30 being adapted to drive the tire assembly 10 and the second propeller 42 to rotate in opposite directions.

[0091] Furthermore, in some embodiments, the rotation direction of the first propeller 41 is the same as the rotation direction of the tire assembly 10, and opposite to the rotation direction of the second propeller 42.

[0092] In this way, the two propellers rotate in opposite directions, which ensures that the vehicle 300 has sufficient power to travel in the water, while eliminating the rolling torque caused by the unidirectional rotation of the propellers, allowing the vehicle 300 to travel smoothly in a straight line in the water.

[0093] Specifically, the first propeller 41 of the propeller assembly 40 is disposed on the tire assembly 10, so that the first propeller 41 can rotate in the same direction as the tire assembly 10 relative to the central shaft support 20 (e.g., clockwise rotation); the second propeller 42 of the propeller assembly 40 is disposed on the central shaft support 20, so that the second propeller 42 can rotate in the opposite direction as the tire assembly 10 relative to the central shaft support 20 (e.g., counterclockwise rotation). In this way, the drive assembly 30 can drive the first propeller 41 and the second propeller 42 to rotate in opposite directions, eliminating the roll torque caused by the unidirectional rotation of the propellers.

[0094] Of course, in some implementations, the two propellers can also rotate in the same direction to adjust the attitude of the vehicle 300 in the water using the roll torque.

[0095] In some embodiments, the helical direction of the first propeller 41 is opposite to that of the second propeller 42.

[0096] In this way, when the two propellers rotate in opposite directions, they can provide thrust to the vehicle 300 in the same direction.

[0097] Specifically, the spiral direction of the first propeller 41 causes the water to flow backward when the first propeller 41 rotates clockwise, thereby generating forward thrust.

[0098] The spiral direction of the second propeller 42 causes the first propeller to rotate clockwise, which pushes the water flow forward and generates a backward thrust.

[0099] For example, when the first propeller 41 rotates clockwise and the second propeller 42 rotates counterclockwise, the two propellers can simultaneously push the water flow backward, thereby generating forward thrust, enabling the vehicle 300 to move forward in the water.

[0100] When the first propeller 41 rotates counterclockwise and the second propeller 42 rotates clockwise, both propellers can push the water forward, thereby generating a backward pull, allowing the vehicle 300 to move backward in the water.

[0101] The embodiments of this application do not limit the specific spiral direction of the first propeller 41 and the second propeller 42, as long as the spiral directions are opposite.

[0102] In some embodiments, the drive assembly 30 includes a first drive member 31 and a second drive member 32. The first drive member 31 is used to drive the tire assembly 10 to rotate relative to the central shaft support 20, and the second drive member 32 is used to drive the second propeller 42 to rotate relative to the central shaft support 20.

[0103] Thus, different driving components can drive the first propeller 41 and the second propeller 42 respectively, so that the first propeller 41 and the second propeller 42 can rotate in opposite directions.

[0104] Specifically, the first drive member 31 is used to drive the tire assembly 10 to rotate relative to the central shaft support 20, while the first propeller 41 connected to the tire assembly 10 rotates in the same direction as the tire assembly 10. The second drive member 32 is used to drive the second propeller 42 to rotate relative to the central shaft support 20, so that the first propeller 41 and the second propeller 42 can rotate in opposite directions.

[0105] For example, when the first drive member 31 rotates clockwise and drives the first propeller 41 to rotate clockwise, the second drive member 32 can drive the second propeller 42 to rotate counterclockwise.

[0106] Of course, in some implementations, it may be necessary for the two propellers to rotate in the same direction, for example, in order to give the vehicle 300 a rolling torque in the water without causing a significant change in the position of the vehicle 300.

[0107] At this time, when the first driving member 31 drives the first propeller 41 to rotate in a clockwise direction, the second driving member 32 can also drive the second propeller 42 to rotate in a clockwise direction; or, when the first driving member 31 drives the first propeller 41 to rotate in a counterclockwise direction, the second driving member 32 can drive the second propeller 42 to rotate in a counterclockwise direction.

[0108] In some embodiments, the tire assembly 10 includes a hub 11 and a tire 12, the tire 12 being mounted on the outer periphery of the rim of the hub 11, and the center axle bracket 20 being coaxially disposed with the hub 11 and at least partially located on the inner side of the hub 11.

[0109] In this way, multiple functions can be achieved on land by utilizing the rotation of tire 12.

[0110] Specifically, the center axle bracket 20 is coaxially arranged with the wheel hub 11 and at least partially located inside the wheel hub 11, allowing the wheel hub 11 to rotate around the center axle bracket 20. Simultaneously, this causes the tire 12, mounted on the outer circumference of the wheel rim of the wheel hub 11, to also rotate around the center axle bracket 20. In this way, the entire tire assembly 10 can rotate around the center axle bracket 20, enabling the vehicle 300 to perform various functions on land using the rotation of the tire 12. For example, the wheels 100 assist the vehicle 300 in driving and steering.

[0111] In some embodiments, the first drive member 31 includes a first stator 311 and a first rotor 312. The first stator 311 is disposed on the central shaft support 20, and the first rotor 312 is connected to the inner side of the hub 11.

[0112] Thus, the hub 11 can rotate around the central shaft support 20 through the first stator 311 and the first rotor 312 of the first drive member 31.

[0113] Specifically, the first stator 311 is fixedly mounted on the central axle support 20, serving as the stationary part of the first drive component 31. The first rotor 312 is connected to the inner side of the wheel hub 11. When a rotational torque is generated between the first stator 311 and the first rotor 312, the torque drives the first rotor 312 to rotate, thereby causing the wheel hub 11 connected to the first rotor 312 to rotate. The wheel hub 11 then drives the first propeller 41 to rotate around the central axle support 20. In this way, the tire assembly 10 can rotate around the central axle support 20 to achieve the corresponding functions of the vehicle 300.

[0114] For example, the first stator 311 can be close to the first rotor 312 on the inner side of the hub 11, thereby providing the first rotor 312 with a large rotational torque. The first stator 311 is also mounted on the central shaft support 20, and there is a certain distance between the central shaft support 20 and the hub 11. Therefore, while the first stator 311 is close to the first rotor 312, the first stator 311 can be provided with corresponding connecting rods and fixedly connected to the central shaft support 20. At the same time, the connecting rods of the first stator 311 should not be too thick, nor should there be too many of them, so as not to obstruct the passage of water flowing through the middle of the wheel 100 when the propeller assembly 40 rotates in the water.

[0115] In some embodiments, the first propeller 41 and the hub 11 are integrally formed.

[0116] In this way, while ensuring that the rotation directions of the first propeller 41 and the hub 11 are consistent, the structural strength of the wheel 100 is increased.

[0117] Specifically, the first propeller 41 and the hub 11 may not be connected by conventional welding points, joints, or connectors, but rather as a seamless or nearly seamless integral continuous structure. This continuity may be achieved through casting, extrusion, stretching, or other special manufacturing processes to ensure that the physical and chemical properties between the first propeller 41 and the hub 11 remain consistent at the connection point.

[0118] For example, the hub 11 includes a rim and spokes, and the hub 11 is generally cast in one piece. When producing the hub 11, the spokes can be designed to resemble the first propeller 41, and a hub 11 with propeller-style spokes can be produced. In this way, the first propeller 41 and the hub 11 can be a one-piece structure.

[0119] In some embodiments, the wheel 100 further includes a first bearing 51 disposed between the first propeller 41 and the central shaft support 20.

[0120] In this way, the first propeller 41 can rotate more smoothly around the central shaft support 20 through the first bearing 51, reducing rotational resistance and improving propeller rotation efficiency.

[0121] Specifically, the first bearing 51 can be fitted onto the central shaft bracket 20, and the first propeller 41 is fitted onto the first bearing 51. Thus, when the first drive member 31 drives the tire assembly 10 to rotate, and the tire assembly 10 in turn drives the connected first propeller 41 to rotate, the first propeller 41 can rotate smoothly on the central shaft bracket 20 via the first bearing 51.

[0122] In some embodiments, the second drive member 32 includes a second stator 321 and a second rotor 322, the second stator 321 being disposed on the central shaft support 20, and the second rotor 322 being connected to the second propeller 42.

[0123] Thus, the second propeller 42 can rotate around the central shaft support 20 via the second stator 321 and the second rotor 322 of the second drive member 32.

[0124] Specifically, the second stator 321 is mounted on the central shaft support 20 as the stationary part of the second driving member 32. The second rotor 322 is connected to the second propeller 42. When a rotational torque is generated between the second stator 321 and the second rotor 322, the second rotor 322 will be driven to rotate, thereby driving the second propeller 42 connected to the second rotor 322 to rotate around the central shaft support 20.

[0125] In some embodiments, the wheel 100 further includes a second bearing 52 disposed between the second propeller 42 and the central shaft support 20.

[0126] In this way, the second propeller 42 can rotate more smoothly around the central shaft support 20 through the second bearing 52, reducing rotational resistance.

[0127] Specifically, the second bearing 52 can be fitted onto the central shaft support 20, and the second propeller 42 is fitted onto the second bearing 52, so that the second propeller 42 can rotate smoothly on the central shaft support 20 through the second bearing 52.

[0128] In some embodiments, the magnetic flux direction of the second drive member 32 is along the axial direction of the central shaft support 20.

[0129] This makes the space utilization of wheel 100 more compact, while improving the propeller's propulsion efficiency.

[0130] Specifically, the second drive unit 32 is preferably an axial flux motor, which can reduce the axial dimension of the drive unit compared to a radial flux motor, making the axial space utilization of the wheel 100 more compact. At the same time, in order to increase the water flow through the tire assembly 10 when the vehicle 300 is traveling in water and improve the propeller propulsion efficiency, it is also necessary to control the radial dimension of the axial flux motor.

[0131] Of course, the second drive element 32 can also be a radial flux motor. This application does not limit the type of motor used for the second drive element 32 to meet various needs.

[0132] In some embodiments, the magnetic flux direction of the first drive member 31 is along the radial direction of the central shaft support 20.

[0133] In this way, the power performance of the first drive component 31 can be guaranteed, while saving space between the central shaft bracket 20 and the first drive component 31.

[0134] Specifically, the first drive unit 31 is preferably a radial flux motor. The first stator 311 of the radial flux motor can be close to the first rotor 312 on the inner side of the wheel hub 11. The first stator 311 is provided with a connecting rod and is fixedly connected to the central axle bracket 20. This can save space between the central axle bracket 20 and the first drive unit 31, that is, it can save radial space in the middle of the wheel 100. This ensures the passage of water through the tire assembly 10 when the vehicle 300 is traveling in water.

[0135] Of course, it is also necessary to control the radial dimension and axial dimension of the radial flux motor to avoid encroaching on the setting position of the second drive component 32.

[0136] In some embodiments, the first drive element 31 may also be an axial flux motor. The embodiments of this application do not limit the type of motor used for the first drive element 31 to meet various needs.

[0137] This application provides a wheel system 200, including a wheel 100 and a rollover assembly 210 as described in any of the above embodiments.

[0138] Thus, the position and direction of the wheel 100 can be adjusted by the flipping component 210 to achieve a variety of functions.

[0139] Specifically, the position of the spare tire-modified wheel 100 can be adjusted via the flip component 210. When driving normally on land, adjusting the position of the wheel 100 can achieve multiple functions such as assisting with U-turns, assisting with parallel parking, and lifting the rear wheels of the vehicle 300.

[0140] When traveling in water, the position of the wheel 100 can be adjusted by the flipping component 210 so that the wheel 100 enters the water, while driving the propeller component 40 to rotate, providing power for the vehicle 300 to travel in water, or adjusting the direction of travel of the vehicle 300 so that the vehicle 300 can meet various passage conditions.

[0141] Meanwhile, by adjusting the tilting angle of the wheel 100 through the tilting component 210, the front and rear weight distribution of the vehicle 300 can be balanced, preventing the vehicle 300 from being front-heavy. When not in use, the tilting component 210 can also adjust the position of the wheel 100, making the wheel 100 disguised as a spare tire, ensuring the aesthetic appearance of the vehicle, while not affecting the vehicle 300's land driving.

[0142] In some embodiments, the flipping assembly 210 includes a third drive member 211 and a flipping rod 212. The flipping rod 212 is connected to the central shaft bracket 20, and the third drive member 211 is connected to the flipping rod 212 to drive the wheel 100 to move between a first predetermined position and a second predetermined position.

[0143] When the wheel 100 is in the first predetermined position, the wheel 100 will not contact the ground or the water surface;

[0144] When the wheel 100 is in the second predetermined position, the wheel 100 is in contact with the ground or water surface.

[0145] Thus, by adjusting the wheel 100 to different positions using the flipping component 210, multiple functions can be achieved.

[0146] Specifically, the third drive member 211 is connected to the flipping rod 212, the flipping rod 212 is connected to the central axle support 20 of the wheel 100, and the third drive member 211 drives the flipping rod 212 to flip, so that the wheel 100 connected to the flipping rod 212 can move between a first predetermined position and a second predetermined position.

[0147] In one embodiment, when the wheel 100 is not in use, the third drive member 211 drives the tilting rod 212 to tilt, so that the wheel 100 connected to the tilting rod 212 can be in a first predetermined position (e.g., Figure 4 For example, wheel 100 can be adjusted to fit against the trunk door of vehicle 300, making wheel 100 appear as a spare tire. In this case, even if vehicle 300 enters water, wheel 100 will not come into contact with the water surface.

[0148] In another embodiment, when wheel 100 is needed, the third drive member 211 drives the tilting rod 212 to tilt, so that wheel 100 connected to the tilting rod 212 can be in a second predetermined position (e.g., Figure 5 This allows the wheels 100 to contact the ground or water surface. For example, on land, adjusting the wheels 100 to contact the ground can assist in turning around, assist in parallel parking, and improve the steering flexibility of the vehicle 300, among other functions. Alternatively, in water, adjusting the wheels 100 to contact the water surface, or even having the wheels 100 fully submerged in the water, can drive the propeller assembly 40 to rotate, providing the vehicle 300 with the power to travel in the water. At the same time, the direction and attitude of the vehicle 300 in the water can be adjusted, allowing the vehicle 300 to meet various traffic conditions.

[0149] Of course, the wheel 100 can also be flipped to between the first and second predetermined positions as needed, for example, to balance the front and rear weight distribution of the vehicle 300. Alternatively, the wheel 100 can be adjusted to a horizontal position to form a platform with a certain load-bearing capacity, used for placing items or providing a place for people to rest or sit. This application's embodiments do not limit the flipping structure of the flipping component 210 or the position of the wheel 100 to meet various needs.

[0150] It should be noted that when using the flipping assembly 210 to flip the wheel 100, sufficient space should be left for flipping to avoid damage to the corresponding parts.

[0151] In some embodiments, the flipping assembly 210 further includes a mounting bracket 213, which is fixed to the body 310 of the vehicle 300. A third driving member 211 is disposed on the mounting bracket 213 and drives the two ends of the flipping rod 212 to rotate synchronously.

[0152] In this way, the aforementioned wheel 100 can be installed on the vehicle body 310, and the vehicle body 310 can provide support for the wheel 100, making it easier to use the wheel 100.

[0153] Specifically, the wheel 100 is connected to the tilting rod 212 and the mounting bracket 213, which is fixed to the body 310 of the vehicle 300, allowing the wheel 100 to be mounted on the body 310. Simultaneously, the third drive member 211 of the mounting bracket 213 can drive both ends of the tilting rod 212 to rotate, causing the wheel 100 to rotate relative to the mounting bracket 213, conveniently providing the vehicle 300 with various functions. This embodiment does not limit the position of the mounting bracket 213 on the body 310 to meet various needs. For example, the wheel 100 can be mounted at the upper rear of the vehicle, at the lower rear, or even at other locations besides the rear.

[0154] In some embodiments, the wheel system 200 further includes a steering assembly 220, which is connected to the tilting assembly 210 and the wheel 100 respectively. The steering assembly 220 can drive the wheel 100 to rotate between a first posture and a second posture.

[0155] When wheel 100 is in the first posture, wheel 100 is in contact with the ground;

[0156] When wheel 100 is in the second posture, wheel 100 is in contact with the ground or water surface.

[0157] In this way, the steering assembly 220 can adjust the wheel 100 to different postures (that is, the direction of the wheel 100 can be adjusted) to achieve multiple functions.

[0158] Specifically, when the vehicle 300 lacks power while driving on land, the steering assembly 220 can bring the wheels 100 into a first posture (e.g., Figure 6 At this point, wheel 100 is oriented in the same direction as the rear wheels of vehicle 300, and the central axle support 20 of wheel 100 is parallel to the width direction of vehicle 300. In this way, wheel 100 can enhance the power of vehicle 300, improve its traction, and help vehicle 300 get out of trouble when going uphill or getting stuck. Furthermore, in the event of a tire blowout, wheel 100 can also provide support and power to vehicle 300, balancing its weight and allowing vehicle 300 to continue moving.

[0159] Of course, wheel 100 can also be in a second posture (such as...) Figure 7At this point, the wheel 100 is oriented at a 90-degree angle to the rear wheel of the vehicle 300, and the central axle support 20 of the wheel 100 is parallel to the length of the vehicle 300. When the vehicle 300 is on land, the lateral wheel 100 can help the vehicle 300 to perform lateral parking in narrow spaces; or, it can help the vehicle 300 to turn around in narrow spaces, improving the vehicle 300's maneuverability. When the vehicle 300 is traveling in water, the rotation of the lateral wheel 100 drives the propeller assembly 40 to rotate, providing power to the vehicle 300 traveling in water.

[0160] In some embodiments, when the vehicle 300 is traveling in water, the wheels 100 can also be in a first posture. When the wheels 100 rotate, they drive the propeller assembly 40 to rotate, providing a lateral force in the width direction of the vehicle 300 to the rear of the vehicle, so that the vehicle 300 can turn or make a U-turn in the water. The embodiments of this application do not limit the application scenario corresponding to a certain wheel 100 posture, and the wheel 100 posture can be flexibly adjusted according to the usage requirements to meet various needs.

[0161] Furthermore, different predetermined positions and postures of the wheel 100 can be combined with each other. For example, when the wheel 100 is in the first predetermined position, it can be in either the first or the second posture; similarly, when the wheel 100 is in the second predetermined position, it can also be in either the first or the second posture. The embodiments of this application do not limit the posture of the wheel 100 when it is in a predetermined position, in order to meet various needs. Of course, the wheel 100 can also be in a posture between the first and second postures.

[0162] In some embodiments, the steering assembly 220 includes a fourth drive member 221 and a swing arm 222. The swing arm 222 is connected to the central axle support 20. The fourth drive member 221 is disposed on the tilting assembly 210 and connected to the swing arm 222 to drive the wheel 100 to switch between a first posture and a second posture.

[0163] Thus, the wheel 100 can switch between the first and second postures through the fourth drive component 221 and the swing arm 222.

[0164] Specifically, the fourth drive component 221 can be fixed at the middle position of the tilting rod 212, allowing it to rotate together with the tilting rod 212. Simultaneously, one side of the swing arm 222 is connected to the central axle bracket 20 of the wheel 100, and the other side is connected to the fourth drive component 221. This allows the wheel 100 to be rotated by the fourth drive component 221 via the swing arm 222, enabling it to switch between a first and a second posture. In this way, the wheel 100 can function as a swivel wheel, providing multiple functions for the vehicle 300 on which it is mounted.

[0165] In some embodiments, when the wheel 100 is in the second posture, the wheel 100 is able to press against the ground to lift the rear wheel of the vehicle 300.

[0166] In this way, the rear wheels of the vehicle 300 can be lifted, and the rear of the vehicle can be moved in an arc with the front of the vehicle as the center. This increases the maneuverability of the vehicle 300.

[0167] Specifically, after the vehicle 300 is parked, the wheels 100 can initially be in a first position. The first drive unit 31 is activated, causing the wheels 100 to roll against the ground towards the front of the vehicle. Simultaneously, the third drive unit 211 of the tilting assembly 210 drives the tilting rod 212, which in turn drives the swing arm 222 to continue rotating forward of the vehicle 300, ultimately moving the wheels 100 to a second predetermined position. This allows the wheels 100 to contact the ground, lifting the rear wheels of the vehicle 300. After lifting the rear wheels, the fourth drive unit 221 rotates, causing the wheels 100 to return to the second position.

[0168] At this point, an arc can be drawn using the front of the vehicle as the center and the length of the vehicle as the radius, utilizing the wheels 100. This allows the rear of the vehicle to move in an arc, assisting the vehicle 300 in completing functions such as turning around or parallel parking, increasing the vehicle 300's flexibility.

[0169] This application provides a vehicle 300, including a wheel 100 of any of the above embodiments; or a wheel system 200 of any of the above embodiments.

[0170] Vehicle 300 can be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, or a gasoline-powered vehicle. Vehicle 300 can also include cars, trucks, buses, lorries, trailers, etc. Specific categories are not limited here.

[0171] In the wheel 100, wheel system 200, and vehicle 300 of this application embodiment, the wheel 100 includes a tire assembly 10, a central axle support 20, a drive assembly 30, and a propeller assembly 40. At least a portion of the propeller assembly 40 is disposed on the tire assembly 10. The drive assembly 30 is adapted to drive the tire assembly 10 to rotate relative to the central axle support 20 and to drive at least a portion of the propeller assembly 40 to rotate. Thus, by combining the drive assembly 30 and the propeller assembly 40, the spare tire position of the vehicle 300 can be used for water propulsion, enabling the vehicle 300 to travel on both land and water simultaneously. By modifying the spare tire position, which is not normally used, the functionality of the vehicle 300 is improved without changing its original form.

[0172] In the wheel 100, wheel system 200, and vehicle 300 of this application embodiment, the wheel system 200 includes a tilting assembly 210 and a steering assembly 220. The steering assembly 220 is disposed on the tilting assembly 210 for adjusting the attitude of the wheel 100, and the tilting assembly 210 is fixed to the vehicle body 310 for adjusting the position of the wheel 100. Thus, different combinations of wheel 100 positions and attitudes bring a variety of practical functions to the vehicle 300.

[0173] In some embodiments, the vehicle 300 also includes a body 310, with the wheel system 200 located on the outside of the trunk of the body 310.

[0174] In this way, the overall aesthetics of the vehicle can be maintained without affecting the normal operation of the vehicle 300. At the same time, the wheel system 200 is set in this position, which allows the vehicle 300 to use the wheels 100 to perform various functions.

[0175] Specifically, when the aforementioned wheel 100 is not in use, the third drive component 211 drives the tilting rod 212 to tilt, allowing the wheel 100 connected to the tilting rod 212 to be in a first predetermined position. For example, the wheel 100 can be adjusted to fit against the trunk door of the vehicle 300, disguised as a spare tire, ensuring the overall aesthetics of the vehicle without affecting its normal operation. Alternatively, a regular spare tire can be directly modified into the aforementioned wheel 100, enriching the functionality of the vehicle 300's spare tire. When the aforementioned wheel 100 is in use, since the wheel system 200 is located on the outside of the trunk of the vehicle body 310, the position and attitude of the wheel 100 can be quickly and easily adjusted, thereby achieving various functions.

[0176] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0177] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
