[0034] Next, with reference to the accompanying drawings, a propulsion device 10 of a vehicle according to some embodiments of the present disclosure is described.

[0035] As shown in FIGS. 1-5, the propulsion device 10 of a vehicle according to some embodiments of the present disclosure includes a driving assembly 1, a tire assembly 2, and a propeller 3, the driving assembly 1 includes a stator 11, a first rotor, and a second rotor, the stator 11 drives at least one of the first rotor or the second rotor to rotate, one of the first rotor and the second rotor is connected with the tire assembly 2, and the other of the first rotor and the second rotor is connected with the propeller 3.

[0036] Thus, integrated design is achieved, which is conducive to simplifying the structure, and the propeller 3 and the tire assembly 2 do not interfere with each other, which is conducive to ensuring the operation efficiency of the vehicle 1000.

[0037] First, as shown in FIGS. 1-2, the propulsion device 10 includes the driving assembly 1, the driving assembly 1 includes the stator 11, the first rotor, and the second rotor, the stator 11 is provided with a first winding and a second winding, the first winding is arranged correspondingly to the first rotor and is used for coupling and cooperating with the first rotor, and the second winding is arranged correspondingly to the second rotor and is used for coupling and cooperating with the second rotor.

[0038] For example, when the first winding is powered, the stator 11 can drive the first rotor to rotate; when the second winding is powered, the stator 11 can drive the second rotor to rotate; and when the first winding and the second winding are powered at the same time, the stator 11 can drive the first rotor and the second rotor to rotate, respectively.

[0039] For example, the propulsion device 10 further includes the tire assembly 2 and the propeller 3, one of the first rotor and the second rotor is connected with the tire assembly 2, and the other of the first rotor and the second rotor is connected with the propeller 3.

[0040] For example, the first rotor can be connected with the tire assembly 2, so that the first rotor can drive the tire assembly 2 to rotate synchronously, and the second rotor can be connected with the propeller 3, so that the second rotor can drive the propeller 3 to rotate synchronously.

[0041] In some embodiments of the present disclosure, as shown in FIGS. 3-5, the tire assembly 2 can be provided as a spare tire 203 of the vehicle 1000, and the propulsion device 10 can be switched between an open position and a stowed position.

[0042] When the propulsion device 10 is switched to the open position, the spare tire 203 moves to the lower part of the vehicle body 200, at this time, if the vehicle 1000 is on the ground, the spare tire 203 can be supported on the ground, if the vehicle 1000 is on the water, the spare tire 203 and the propeller 3 can extend into the water, the spare tire 203 is used to provide buoyancy, and the propeller 3 is used to provide thrust; while the propulsion device 10 is switched to the stowed position, the spare tire 203 and the propeller 3 are attached to the back door 201 of the vehicle body 200 to avoid affecting the normal driving of the vehicle 1000 on the ground.

[0043] Of course, the spare tire 203 can also be installed on the floor of the vehicle body 200; or the tire assembly 2 can be provided as a wheel 202 of the vehicle 1000, which is not limited in the present disclosure.

[0044] It can be understood that when the vehicle 1000 is on land, one of the first rotor and the second rotor can be driven to move by the stator 11 to drive the tire assembly 2 to rotate, thereby driving the vehicle 1000 to move on land, and when the vehicle 1000 is on water, the other one of the first rotor and the second rotor can be driven to move by the stator 11 to drive the propeller 3 to rotate, thereby driving the vehicle 1000 to move on water. Thus, integrated design can be achieved, which is beneficial to simplify the structure.

[0045] In addition, when the vehicle 1000 is driving on water, the propeller 3 can be rotated while the tire assembly 2 is not rotated to avoid the problem of flow resistance caused by the rotation of the tire assembly 2 in water, which is beneficial to improve the operating efficiency of the vehicle 1000, and when the vehicle 1000 is driving on land, the tire assembly 2 can be rotated while the propeller 3 is not rotated to avoid the idling of the propeller 3, which is beneficial to reduce energy consumption.

[0046] The propulsion device 10 of the vehicle according to some embodiments of the present disclosure can be used to drive the tire assembly 2 to rotate to drive the vehicle 1000 to move on land, and can be used to drive the propeller 3 to rotate to push the vehicle 1000 to move on water, which achieves integrated design, is beneficial to simplify the structure, and the propeller 3 and the tire assembly 2 do not interfere with each other, which is beneficial to ensure the operating efficiency of the vehicle 1000.

[0047] In some embodiments of the present disclosure, the tire assembly 2 includes a rim 22, and the driving assembly 1 is arranged on the radially inner side of the rim 22.

[0048] For example, referring to FIGS. 1-2, the tire assembly 2 includes a tire 21 and a rim 22, the tire 21 is connected to the outer side of the rim 22, and the rim 22 defines an installation space inside, and the driving assembly 1 is installed in the installation space to be located on the radially inner side of the rim 22. Through the above arrangement, the integration of the propulsion device 10 can be improved, and the driving assembly 1 can be better protected, thereby improving the operating stability of the propulsion device 10.

[0049] In some embodiments of the present disclosure, the rim 22 can be connected to one of the first rotor and the second rotor.

[0050] For example, the first rotor can be connected to the rim 22, so that the first rotor can drive the rim 22 to rotate. In this way, the connection difficulty between the tire assembly 2 and the driving assembly 1 can be reduced, and the connection stability can be improved.

[0051] In some embodiments of the present disclosure, as shown in FIGS. 1-2, the propeller 3 can be arranged at the radially inner side of the driving assembly 1. In this way, the space in the propulsion device 10 can be fully utilized, which is conducive to improving the integration of the propulsion device 10.

[0052] In some embodiments of the present disclosure, as shown in FIGS. 1-2, the first rotor can be configured as the outer rotor 12, and the second rotor can be configured as the inner rotor 13. In the radial direction of the outer rotor 12, the stator 11 is arranged between the inner rotor 13 and the outer rotor 12.

[0053] That is, the outer rotor 12 is located at the radially outer side of the stator 11 and coupled with the first winding of the stator 11, and the inner rotor 13 is located at the radially inner side of the stator 11 and coupled with the second winding of the stator 11.

[0054] For example, the propeller 3 can be arranged at the radially inner side of the inner rotor 13 and connected to the inner rotor 13, and the tire assembly 2 can be connected to the outer rotor 12.

[0055] Through the above arrangement, the utilization rate of the driving assembly 1 in the radial space can be improved, and the overall size of the propulsion device 10 is reduced. In addition, the propeller 3 and the remaining components can have less overlap in the axial direction, effectively reducing the flow resistance and improving the propulsion efficiency of the propeller 3.

[0056] Of course, the present disclosure is not limited thereto. For example, the first rotor and the second rotor can both be configured as the inner rotor 13, or the propeller 3 can be connected to the outer rotor 12, and the tire assembly 2 can be connected to the inner rotor 13, which is not limited by the present disclosure.

[0057] In some embodiments of the present disclosure, the spokes of the rim 22 can be configured as the propeller 3. In this way, when the tire assembly 2 rotates, the vehicle 1000 can be propelled on the water, which is conducive to improving the propulsion effect of the propulsion device 10.

[0058] In some embodiments of the present disclosure, when the propeller 3 and the tire assembly 2 rotate at the same time, the rotation directions of the propeller 3 and the tire assembly 2 can be opposite. In this way, the reaction forces of the propeller 3 and the tire assembly 2 can be counteracted, which is conducive to improving the stability of the vehicle 1000 running on the water.

[0059] In some embodiments of the present disclosure, as shown in FIGS. 1-2, the tire assembly 2 comprises a rim 22 connected with the outer rotor 12 through the rotor support frame 4. In this way, the connection between the rim 22 and the outer rotor 12 can be facilitated, and the arrangement between the rim 22 and the outer rotor 12 can be more flexible, thereby improving the practicability of the propulsion device 10.

[0060] In some embodiments of the present disclosure, the outer rotor 12 is fixed to the inner wall of the rotor support frame 4 to drive the rotor support frame 4 to rotate, and the rim 22 is connected with the rotor support frame 4.

[0061] For example, referring to FIGS. 1-2, the rotor support frame 4 is provided with an open accommodating cavity 41, and the drive assembly 1 is arranged in the accommodating cavity 41, so that the drive assembly 1 can be placed in the accommodating cavity 41.

[0062] In addition, the outer rotor 12 can be fixed to the inner wall of the rotor support frame 4, so that the outer rotor 12 can drive the rotor support frame 4 to rotate, and the rim 22 can be connected with the middle part of the rotor support frame 4, so that the outer rotor 12 can drive the rim 22 to rotate synchronously through the rotor support frame 4.

[0063] Through the above arrangement, the integration of the propulsion device 10 can be improved, and the mounting point of the rim 22 can be closer to the rotation axis, thereby improving the mounting stability of the tire assembly 2.

[0064] In some embodiments of the present disclosure, the rim 22 is detachably connected with the rotor support frame 4. For example, the rotor support frame 4 is provided with a threaded member 42, the threaded member 42 penetrates the rotor support frame 4 and the rim 22 in sequence along the axial direction and is connected with a nut (not shown in the figure), so as to detachably fix the rim 22 on the rotor support frame 4.

[0065] In this way, the tire assembly 2 can be disassembled and replaced to meet the use requirements of the tire assembly 2, such as serving as a spare tire 203, thereby improving the practicability of the propulsion device 10.

[0066] In some embodiments of the present disclosure, the propulsion device 10 of the vehicle further comprises a support shaft 5, and the tire assembly 2 and the propeller 3 are respectively rotationally connected with the support shaft 5.

[0067] For example, referring to FIG. 1, the propulsion device 10 further comprises a support shaft 5, and the tire assembly 2 and the propeller 3 are respectively supported on the support shaft 5 through a bearing 51, so that the tire assembly 2 and the propeller 3 can rotate around the support shaft 5.

[0068] In this way, the integration design of the propulsion device 10 can be realized, and the rotation stability of the tire assembly 2 and the propeller 3 can be improved, thereby improving the reliability of the propulsion device 10. In some embodiments of the present disclosure, the propulsion device 10 of the vehicle further comprises a support shaft 5, and the tire assembly 2 and the propeller 3 are respectively rotationally connected with the support shaft 5.

[0069] Of course, the present disclosure is not limited thereto, and the propulsion device 10 of the vehicle can also include two support shafts 5, and the tire assembly 2 and the propeller 3 are respectively supported on the two support shafts 5. In this way, flexible arrangement of the propulsion device 10 can be achieved.

[0070] In some embodiments of the present disclosure, the first rotor is an outer rotor 12, and the second rotor is an inner rotor 13. In the radial direction of the outer rotor 12, the stator 11 is arranged between the inner rotor 13 and the outer rotor 12, and the stator 11 is connected to the support shaft 5 through a stator support frame 52.

[0071] For example, referring to FIGS. 1-2, the first rotor can be configured as an outer rotor 12 located radially outside the stator 11 and coupled to the first winding of the stator 11, and the second rotor can be configured as an inner rotor 13 located radially inside the stator 11 and coupled to the second winding of the stator 11.

[0072] For example, the stator 11 can be connected to the support shaft 5 through a stator support frame 52, and the first rotor and the second rotor are respectively rotatably supported on the support shaft 5. In this way, the installation stability of the stator 11 can be improved, so that the stator 11 can better drive the first rotor and the second rotor to rotate.

[0073] In some embodiments of the present disclosure, as shown in FIG. 1, the propeller 3 can be supported on the support shaft 5, and the first rotor can be fixed on the propeller 3, so that the first rotor can be supported on the support shaft 5 through the propeller 3. In this way, the first rotor does not need to be provided with a separate rotor support frame 4, which can simplify the structure of the propulsion device 10, reduce the cost, and reduce the size of the propulsion device 10.

[0074] In some embodiments of the present disclosure, as shown in FIG. 1, the rotor support frame 4 can be supported on the support shaft 5, and the second rotor and the tire assembly 2 can be respectively installed on the rotor support frame 4, so that the support shaft 5 can support the second rotor and the tire assembly 2. Through the above arrangement, when the tire assembly 2 is replaced, the second rotor does not need to be replaced, which is beneficial to reduce the maintenance cost.

[0075] Some embodiments of the present disclosure also provide a propulsion device 100 of a vehicle.

[0076] As shown in FIGS. 1-2, the propulsion device 100 of the vehicle according to some embodiments of the present disclosure includes a propulsion device 10 and a mounting assembly 20. The propulsion device 10 is the propulsion device 10 described above. The mounting assembly 20 is connected to the propulsion device 10 to mount the propulsion device 10 to a vehicle body 200.

[0077] The propulsion device 100 of the vehicle according to some embodiments of the present disclosure, the driving assembly 1 can be used to drive the tire assembly 2 to rotate to drive the vehicle 1000 to move on land, and can be used to drive the propeller 3 to rotate to push the vehicle 1000 to move on water, realizing integrated design, facilitating to simplify the structure, and the propeller 3 and the tire assembly 2 do not interfere with each other, which is beneficial to guarantee the operation efficiency of the vehicle 1000, and improves the practicability of the propulsion device 100.

[0080] For example, as shown in FIGS. 3-5, when the vehicle 1000 is on land, if the vehicle 1000 is in normal driving, the propulsion device 10 can be switched to the stowed position by the connecting assembly 6, so that the tire assembly 2 is switched to the stowed position, thereby avoiding the tire assembly 2 from interfering with the normal driving of the vehicle 1000; if the vehicle 1000 needs to turn in place, the propulsion device 10 can be switched to the open position by the connecting assembly 6, so that the tire assembly 2 can be switched to the open position to be supported on the ground, so that the vehicle 1000 can turn in place or move by the tire assembly 2.

[0081] When the vehicle 1000 is on water, if the vehicle 1000 is in normal driving, the propulsion device 10 can be switched to the open position by the connecting assembly 6 to drive the propeller 3 to switch to the open position, so that the propeller 3 can extend into the water, so that the vehicle 1000 can move forward or backward under the push of the propeller 3; if the vehicle 1000 needs to land, the propulsion device 10 can be switched to the stowed position by the connecting assembly 6 to drive the propeller 3 to switch to the stowed position, thereby avoiding the propeller 3 from interfering with the ground and causing damage.

[0082] In addition, when the vehicle 1000 is normally driven on water, the speed and forward and backward direction of the vehicle 1000 on water can be adjusted by adjusting the rotating speed and direction of the propeller 3. When the vehicle 1000 encounters waves on water, the angle of the propeller 3 can be adjusted by the connecting assembly 6, so as to adjust the angle between the thrust and the horizontal direction, so as to balance the impact of the waves on water, thereby improving the stability of the vehicle on water.

[0083] And, when the vehicle 1000 is steering on water, steering can be realized by rotating the propeller 3 in cooperation with the wheel 202 of the vehicle 1000. Thus, the practicability of the propulsion device 100 can be improved.

[0084] In some embodiments of the present disclosure, as shown in FIGS. 1-3, the propulsion device 100 of the vehicle further comprises a bracket 7 mounted on the vehicle body 200, the fixed end 63 of the connecting assembly 6 is rotatably mounted on the bracket 7, and the movable end of the connecting assembly 6 is connected with the propulsion device 10, and the connecting assembly 6 is used to rotate around the bracket 7 to drive the propulsion device 10 to move, so as to change the position of the propulsion device 10.

[0085] Through the above arrangement, the mounting stability of the connecting assembly 6 can be improved, and the reliability of the propulsion device 100 can be improved.

[0086] In some embodiments of the present disclosure, the propulsion device 100 of the vehicle further comprises a power member 8, which can be configured as a driving motor, the power member 8 is mounted on the bracket 7, and the power member 8 is power-connected with the connecting assembly 6 and is used to drive the connecting assembly 6 to rotate relative to the vehicle body 200, so as to change the position of the propulsion device 10.

[0087] Thus, convenient switching between different working states of the propulsion device 10 can be realized, and the practicability of the propulsion device 100 is improved.

[0089] Through the above arrangement, during the rotation of the connecting assembly 6, the position of the connecting assembly 6 in the lateral direction of the vehicle body can remain unchanged, such as being kept in the middle of the lateral direction of the vehicle body 200, so that the tire assembly 2 and the propeller 3 can better push the vehicle 1000 to move, and the reliability of the propulsion device 100 is improved.

[0090] In some embodiments of the present disclosure, as shown in FIG. 2, the connecting assembly 6 comprises a swing arm 61 extending along a second direction L2, the support shaft 5 extends along a third direction L3, and the first direction L1, the second direction L2 and the third direction L3 are perpendicular to each other.
