[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] The following is for reference. Figures 1-3 A spare tire assembly 100 according to a first aspect of the present invention is described.

[0038] like Figure 1 and Figure 2 As shown, according to a first aspect embodiment of the present invention, a spare tire assembly 100 is adapted to be disposed on the rear side of the body 200 of a vehicle 1000, and the spare tire assembly 100 includes: a wheel 10, a propeller 20 and a drive mechanism 30.

[0039] Specifically, the propeller 20 and the wheel 10 are arranged coaxially, and the drive mechanism 30 is connected to the propeller 20 to drive the propeller 20 to rotate. The spare tire assembly 100 has a synchronous state and an asynchronous state. In the synchronous state, the wheel 10 and the propeller 20 are fixedly connected. In the asynchronous state, the wheel 10 and the propeller 20 are separated and can rotate relative to each other.

[0040] The spare tire assembly 100 can be used in the amphibious vehicle 1000. When the vehicle 1000 is traveling in water, the drive mechanism 30 drives the propeller 20 located at the rear of the vehicle body 200 to rotate, which can drive the vehicle 1000 to travel in water. The air in the wheel 10 can increase the levitation force of the vehicle 1000 in the water. At this time, the spare tire assembly 100 can be adjusted to an asynchronous state, and the wheel 10 is separated from the propeller 20. In this way, the driving force on the drive mechanism 30 will not act on the wheel 10, so that the drive power of the drive mechanism 30 to the propeller 20 can be higher, thereby ensuring the driving effect of the propeller 20 on the vehicle 1000.

[0041] As will be understood by those skilled in the art, when the vehicle 1000 is driving on land, the spare tire assembly 100 will not affect the normal driving of the vehicle 1000 under normal circumstances. By mounting the propeller 20 on the spare tire assembly 100, the spare tire assembly 100 will not affect the normal driving of the vehicle 1000 during normal driving on land.

[0042] When vehicle 1000 is traveling on land, if it needs to make a U-turn or turn when it reaches a narrow road, but it is difficult to adjust the direction of vehicle 200, the height of spare tire assembly 100 at the rear of vehicle 200 can be adjusted so that spare tire assembly 100 contacts the ground and is adjusted to a synchronized state. At this time, spare tire assembly 100 can act as a drive wheel to drive vehicle 1000. Drive mechanism 30 drives propeller 20 and wheel 10 to rotate. In this way, the rotation of wheel 10 at the rear of vehicle 200 can cause vehicle 200 to swing left and right, thus making it easier for vehicle 1000 to adjust the direction of vehicle 200 to make a U-turn or turn on narrow roads.

[0043] According to the first aspect of the present invention, the spare tire assembly 100 can provide driving force when the vehicle 1000 is traveling on water by integrating the propeller 20 onto the spare tire assembly 100, without affecting the normal driving of the vehicle 1000 on land. By setting a synchronization state, it is convenient to adjust the direction of the vehicle body 200 on narrow roads to achieve operations such as turning or making U-turns.

[0044] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the drive mechanism 30 includes an inner and outer rotor assembly 32 and a stator assembly 31. The propeller 20 is fixed to the rotor assembly 32. In the synchronous state, the wheel 10 is fixed to the rotor assembly 32; in the asynchronous state, the wheel 10 is separated from the rotor assembly 32. In the synchronous state, when the drive mechanism 30 is working, the rotor assembly 32 drives the wheel 10 and the propeller 20 to rotate. In the asynchronous state, when the drive mechanism 30 is working, the rotor assembly 32 drives the propeller 20 to work. Thus, the drive mechanism 30 can drive the propeller 20 to rotate and drive the wheel 10 and the propeller 20 in the synchronous state. The drive mechanism 30 is configured as a motor, which facilitates its placement on the spare tire assembly 100. Furthermore, the motor has a faster response speed, improving the response speed of the spare tire assembly 100's state switching and thus enhancing the user experience. It should be noted that the propeller 20 can be integrated with the rotor 321 of the rotor assembly 32, or the propeller 20 can be a separate component fixedly connected to the rotor 321. During the product design process, the connection relationship between the propeller 20 and the rotor 321 can be adjusted according to the product design requirements, such as the required connection strength between the propeller 20 and the rotor 321 or the required assembly of the propeller 20 and the rotor 321.

[0045] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the rotor assembly 32 is arranged radially inside the stator assembly 31. The spare tire assembly 100 also includes a support shaft 40, on which both the rotor assembly 32 and the wheel 10 are rotatably mounted. The stator assembly 31 is fixed to the support shaft by a stator bracket 311. The support shaft 40 provides support for the wheel 10 and the drive mechanism 30, enabling the drive mechanism 30 to rotate the propeller 20 and the wheel 10. Furthermore, the support shaft 40 is connected to the vehicle body 200, allowing the spare tire assembly 100 to be mounted on the vehicle body 200.

[0046] In some embodiments of the present invention, such as Figure 3 As shown, the spare tire assembly 100 also includes a clutch mechanism 50, which includes a first mating component 51 and a second mating component 52. One of the first mating component 51 and the second mating component 52 is fixed to the rotor assembly 32, and the other is connected to the wheel 10. In a synchronous state, the first mating component 51 and the second mating component 52 are connected as one unit, and in an asynchronous state, the first mating component 51 and the second mating component 52 are separated. Thus, by switching the connection state of the first mating component 51 and the second mating component 52 in the clutch mechanism 50, the connection state of the wheel 10 and the propeller 20 can be switched, thereby realizing the switching of the spare tire assembly 100 between synchronous and asynchronous states.

[0047] In some embodiments of the present invention, the clutch mechanism 50 is disposed between the rotor assembly 32 and the wheel 10 in the axial direction of the rotor assembly 32. This reduces the difficulty of connecting the clutch mechanism 50 to the wheel 10 and the rotor assembly 32, and the wheel 10 and rotor assembly 32 can provide shelter for the clutch mechanism 50, reducing the probability of the clutch mechanism 50 being damaged by external forces, thereby improving the reliability of the spare tire assembly 100 during operation.

[0048] In some embodiments of the present invention, in a synchronous state, the first mating component 51 and the second mating component 52 are magnetically attracted, while in an asynchronous state, the first mating component 51 and the second mating component 52 have no magnetic attraction or are magnetically repelled. Thus, the connection state of the first mating component 51 and the second mating component 52 can be switched. The magnetic attraction response is rapid, and the magnetic attraction structure is simple. By achieving the switching between synchronous and asynchronous states of the spare tire assembly 100 through the magnetic attraction and disengagement of the first mating component 51 and the second mating component 52, the response speed of the spare tire assembly 100 can be improved, and the design and assembly difficulty of the spare tire assembly 100 are relatively low.

[0049] In some embodiments of the present invention, one of the first mating component 51 and the second mating component 52 is a coil and the other is a magnetic component. Thus, when the coil is energized, it generates a magnetic field. Under the influence of this magnetic field, the magnetic component and the coil are magnetically attracted. When the coil is de-energized, the magnetic field disappears, thereby eliminating the magnetic force acting on the magnetic component, and the coil separates from the magnetic component. This allows for the magnetic attraction and disengagement of the first mating component 51 and the second mating component 52, enabling the spare tire assembly 100 to switch between synchronous and asynchronous states. Changing the magnetic field state by controlling the coil's energization is easy to implement and responds quickly, further improving the response speed of the spare tire assembly 100 and reducing its design and assembly complexity.

[0050] In some embodiments of the present invention, the first mating part 51 is fixed to the rotor assembly 32, the first mating part 51 is a coil, and the second mating part 52 is connected to the wheel 10, the second mating part 52 is a magnetic element. It can be understood that there is more space on the rotor assembly 32, so the wires electrically connected to the coil are easier to arrange on the spare tire assembly 100, thereby reducing the difficulty of product design.

[0051] In some embodiments of the present invention, such as Figure 3As shown, the second mating member 52 is movable relative to the wheel 10 between the initial position and the engaged position. In the initial position, the second mating member 52 is spaced apart from the first mating member 51. In the engaged position, the second mating member 52 is connected to the first mating member 51. The clutch mechanism 50 also includes a reset member 53, which is connected between the second mating member 52 and the wheel 10. The reset member 53 is configured to drive the second mating member 52 to move from the engaged position to the initial position.

[0052] When the spare tire assembly 100 switches from an asynchronous state to a synchronous state, the second mating component 52 moves toward the first mating component 51 under the action of the magnetic force and magnetically attracts it, moving from its initial position to the attracted position. When the spare tire assembly 100 switches from a synchronous state to an asynchronous state, the magnetic force disappears, and the second mating component 52 moves from the attracted position to its initial position under the action of the reset component 53. By setting the reset component 53, the reset component 53 can ensure that the second mating component 52 and the first mating component 51 separate when the spare tire assembly 100 is in an asynchronous state, avoiding resistance to the rotation of the rotor assembly 32 by the wheel 10 in the asynchronous state, thereby ensuring the driving effect of the drive mechanism 30 on the propeller 20 in the asynchronous state.

[0053] The reset component 53 can be formed as a spring or an elastic rubber component, thus the structure of the reset component 53 is relatively simple and the assembly difficulty of the reset component 53 is low.

[0054] In some embodiments of the present invention, such as Figure 3 As shown, the rotor assembly 32 includes a rotor 321 and a rotor support 322. The rotor support 322 is arranged radially inside the rotor 321. The rotor support 322 includes an inner ring portion 3221 and a radial extension portion 3222. The inner ring portion 3221 is an annular cylindrical shape. The radial extension portion 3222 is connected to the inner ring portion 3221 and extends outward along the radial direction of the rotor 321. The rotor 321 is located at the end of the radial extension portion 3222 away from the inner ring portion 3221. The coil is sleeved on the outer peripheral surface of the inner ring portion 3221. The magnetic attractor extends in an annular shape around the axis of the rotor 321 and is arranged side by side with the coil in the axial direction of the rotor 321. After assembly, the propeller 20 is fixed on the rotor 321. During the operation of the spare tire assembly 100, the rotor 321 rotates, thereby driving the propeller 20 to rotate. By setting the rotor bracket 322, the rotor bracket 322 can provide support for the rotor 321 and the coil. By setting the rotor 321, the rotor 321 can realize the rotation of the rotor assembly 32 under the action of the magnetic field of the stator assembly 31. By setting the inner ring 3221, it is easy to fix the coil on the rotor assembly 32. By setting the magnetic attractor as a ring, when the coil is magnetically attracted to the magnetic attractor, the magnetic force is more evenly distributed on the magnetic attractor, thereby making the second mating part 52 move towards the first mating part 51 more smoothly.

[0055] In some embodiments of the present invention, such as Figure 3 As shown, the spare tire assembly 100 further includes a first bearing 13 and a second bearing 33, which are sleeved on the support shaft 40. The first bearing 13 is located between the wheel 10 and the support shaft 40, and the second bearing 33 is located between the rotor assembly 32 and the support shaft 40. This allows for a rotatable connection between the wheel 10, the rotor assembly 32, and the support shaft 40. Preferably, there are two second bearings 33, spaced apart axially on the support shaft 40. This improves the stability of the rotor assembly 32 on the support shaft 40, thereby enhancing the stability of the rotor assembly 32 during rotation.

[0056] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the wheel 10 includes a hub 11 and a tire 12. The hub 11 includes a rim, spokes, and an axle connection. The rim is annular. The tire 12 is fitted on the radially outer side of the rim. The axle connection is arranged on the radially inner side of the rim. The axle connection has an axle hole that passes through the axle connection along the axial direction of the wheel 10. There are multiple spokes, which are arranged circumferentially around the axle connection and connected between the axle connection and the rim. The drive mechanism 30 is arranged on one side of the spokes along the axial direction of the wheel 10 and is located on the radially inner side of the rim. After assembly, the propeller 20 is connected to the drive mechanism 30 on the side away from the hub 11. The wheel 10 can provide shielding for the drive mechanism 30 on the radially outer side, reducing the probability of damage to the drive mechanism 30 from the external environment. Furthermore, the spare tire assembly 100 has a more compact structure and smaller size, which facilitates the arrangement of the spare tire assembly 100 on the vehicle 1000.

[0057] The following is for reference. Figures 1-3 A vehicle 1000 according to a second aspect embodiment of the present invention is described.

[0058] like Figure 1 As shown, a vehicle 1000 according to a second aspect embodiment of the present invention includes: a body 200, a spare tire assembly 100 as described in the first aspect embodiment of the present invention, and a drive unit 300.

[0059] Specifically, the spare tire assembly 100 is located on the rear side of the vehicle body 200. The spare tire assembly 100 is movable relative to the vehicle body 200 between an initial position and an extended position. The extended position is located below and behind the initial position. The drive unit 300 is connected to the spare tire assembly 100 to drive the spare tire assembly 100 to move between the initial position and the extended position.

[0060] The vehicle 1000 can travel in water and on land. When the vehicle 1000 is traveling normally on land, the spare tire assembly 100 is in its initial position and does not affect the normal driving of the vehicle 1000. When the vehicle 1000 is driving on a narrow road and it is difficult to adjust its driving direction, the drive unit 300 drives the spare tire assembly 100 to move between the initial position and the extended position and make the wheel 10 contact the ground. Then, the drive mechanism 30 drives the wheel 10 of the spare tire assembly 100 to rotate. The wheel 10 of the spare tire assembly 100 drives the vehicle body 200 to swing left and right at the rear of the vehicle body 200, thereby facilitating the adjustment of the driving direction of the vehicle 1000 on narrow roads.

[0061] When the vehicle 1000 is traveling in water, the drive mechanism 30 drives the propeller 20 to rotate to drive the vehicle 1000. When the vehicle 1000 needs to adjust its angle relative to the water surface, for example when the water surface is large, the drive device 300 drives the spare tire assembly 100 to move, which can adjust the position and angle of the propeller 20's driving force on the vehicle 1000, thereby adjusting the angle of the vehicle 1000 relative to the water surface when traveling in water.

[0062] According to a second aspect embodiment of the present invention, by providing the spare tire assembly 1000 and the drive device 300 according to the first aspect embodiment of the present invention, the spare tire assembly 1000 can drive the vehicle 1000 when driving in water. At the same time, the spare tire assembly 1000 does not affect the normal driving of the vehicle 1000 on land, and can reduce the difficulty of adjusting the driving direction of the vehicle 1000 on narrow roads.

[0063] In some embodiments of the present invention, such as Figure 1 As shown, the drive unit 300 includes a drive motor 310 and a swing arm 320. One end of the swing arm 320 is connected to the drive motor 310, and the other end is connected to the spare tire assembly 100. The drive motor 310 drives one end of the swing arm 320 to rotate around a left-right extending rotation axis. Thus, the drive motor 310 drives the swing arm 320 to rotate, and the swing arm 320 drives the spare tire assembly 100 to rotate, thereby enabling the spare tire assembly 100 to move between an initial position and an extended position. The method of driving the spare tire assembly 100 to move via the drive motor 310 and the swing arm 320 is simple in structure and easy to arrange, reducing product design and assembly difficulty. During the design of the vehicle 1000, the size of the swing arm 320 can be adjusted according to the dimensions of the vehicle 1000, thereby meeting more design needs for the vehicle 1000.

[0064] During normal driving of vehicle 1000, drive motor 310 drives swing arm 320 to rotate and puts spare tire assembly 100 in the initial position; when vehicle 1000 travels to a narrow road, drive motor 310 drives swing arm 320 to rotate and puts wheel 10 of spare tire assembly 100 into contact with the ground, drive mechanism 30 drives wheel 10 to rotate, thereby adjusting the driving angle of vehicle 1000; when vehicle 1000 travels in water, drive motor 310 drives swing arm 320 to rotate, which can adjust the relative position of propeller 20 and vehicle body 200 and the orientation of propeller 20, thereby adjusting the direction of propeller 20's driving force on vehicle 1000.

[0065] When the drive wheel of vehicle 1000 fails and the spare tire needs to be replaced, the drive motor 310 drives the swing arm 320 to rotate to a suitable angle and height, which allows the user to easily remove the wheel 10 from the spare tire assembly 100, thereby improving the user experience.

[0066] In some embodiments of the present invention, such as Figure 1 As shown, the vehicle 1000 also includes a tailgate 210, which is located at the rear of the vehicle body 200. The tailgate 210 allows the interior space to be opened from the rear of the vehicle body 200. The spare tire assembly 100 and the drive unit 300 are mounted on the tailgate 210. In this way, the spare tire assembly 100 and the drive unit 300 do not affect the opening and closing of the tailgate 210. In the initial position, the wheels 10 of the spare tire assembly 100 are in contact with and fixed to the tailgate 210. During normal driving of the vehicle 1000, the stability of the spare tire assembly 100 and its reliability in the initial position can be improved.

[0067] In some embodiments of the present invention, such as Figure 1 As shown, the vehicle 1000 also includes: a bracket 400 connected to the tailgate 210, the bracket 400 having a support hole formed thereon, the main body of the drive motor 310 fixed to the tailgate 210, the output shaft of the drive motor 310 supported in the support hole, and the swing arm 320 connected to the output shaft. By providing the bracket 400, the bracket 400 can provide support for the output shaft of the drive motor 310, thereby improving the stability of the swing arm 320 during rotation and the reliability of the drive motor 310's output shaft supporting the swing arm 320.

[0068] In some embodiments of the present invention, the swing arm 320 has a wiring channel extending along the length of the swing arm 320. The vehicle 1000 further includes a wiring harness disposed within the wiring channel, one end of which is connected to the spare tire assembly 100, and the other end of which is connected to the vehicle controller. This facilitates the arrangement of the wiring harness on the vehicle 1000, and the swing arm 320 provides protection for the wiring harness, reducing the probability of damage to the wiring harness during vehicle 1000 operation and improving the reliability of the vehicle 1000 during operation.

[0069] In some embodiments of the present invention, the vehicle 1000 further includes an electronic control unit (ECU) housed within the vehicle body 200. The ECU is connected to the drive mechanism 30, drive unit 300, and clutch mechanism 50 via wiring harnesses. By incorporating the ECU, the operating states of the drive mechanism 30, drive unit 300, and clutch mechanism 50 can be controlled, thereby enabling the vehicle 1000 to operate normally. Furthermore, by housing the ECU within the vehicle body 200, the vehicle body 200 can provide protection for the ECU, thereby reducing the probability of damage to the ECU during vehicle 1000 operation and improving the reliability of the vehicle 1000 during operation.
