The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0042] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the applicability of other processes and / or the use of other materials.

[0043] A driving device 100 and a vehicle 10000 having the same according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0044] Reference Figures 1-4 According to an embodiment of the first aspect of the present invention, a driving device 100 includes a power assembly 10, a propeller structure 20 and a tire structure 30. The power assembly 10 includes a stator 11 and a first rotor 12 and a second rotor 13 cooperating with the stator 11. The stator 11 can drive the first rotor 12 and / or the second rotor 13 to rotate. The propeller structure 20 is connected to the first rotor 12, and the tire structure 30 is connected to the second rotor 13. The first rotor 12 and the second rotor 13 are arranged on the same side of the stator 11.

[0045] Specifically, refer to Figures 1-4The drive device 100 in the embodiment of the present invention includes a power assembly 10, which serves as a power source and provides power for rotation. The power assembly 10 includes a stator 11 and a first rotor 12 and a second rotor 13 that cooperate with the stator 11. The stator 11 is capable of driving the first rotor 12 and / or the second rotor 13 to rotate. For example, the stator 11 can drive the first rotor 12 or the second rotor 13 to rotate separately, or can drive the first rotor 12 and the second rotor 13 to rotate simultaneously.

[0046] The propeller structure 20 is connected to the first rotor 12 and rotates under the drive of the first rotor 12, thereby propelling the vehicle 10000 through the water. The propeller structure 20 may include one or more blades, for example, two, three, or five blades. If there are multiple blades, they may be evenly arranged along the circumference of the tire structure 30.

[0047] The tire structure 30 is connected to the second rotor 13 to rotate under the drive of the second rotor 13, thereby propelling the vehicle 10000 to travel in the water.

[0048] The first rotor 12 and the second rotor 13 are disposed on the same side of the stator 11. For example, the first rotor 12 and the second rotor 13 can be disposed outside the stator 11, or the first rotor 12 and the second rotor 13 can be disposed inside the stator 11. This reduces the axial space requirement of the power assembly 10, facilitates the axial flow of water, reduces the axial flow resistance of water, improves fluid efficiency, and reduces energy consumption of the power source.

[0049] Therefore, refer to Figures 1-4 According to the drive device 100 of the present invention, a stator 11 is provided, along with a first rotor 12 and a second rotor 13 that cooperate with the stator 11. The first rotor 12 and the second rotor 13 are respectively connected to the propeller structure 20 and the tire structure 30, so that the stator 11 can drive the propeller structure 20 and / or the tire structure 30 to rotate. The first rotor 12 and the second rotor 13 are arranged on the same side of the stator 11, which reduces the axial space required by the power assembly 10, facilitates the axial flow of water, reduces the axial flow resistance of the water, improves fluid efficiency, and reduces the energy consumption of the power source.

[0050] In some embodiments, the stator 11 is connected to the hub 31 of the tire structure 30 to connect the power assembly 10 to the tire structure 30 .

[0051] It is understood that since the stator 11 is connected to the propeller structure 20 and the tire structure 30 via the first rotor 12 and the second rotor 13, respectively, the stator 11 can simultaneously drive the propeller structure 20 and the tire structure 30 to rotate. In this case, the rotational thrust is greater, and the vehicle 10000 moves forward or backward at a faster speed. Of course, the stator 11 can drive the propeller structure 20 and the tire structure 30 to rotate separately. If one of the propeller structure 20 and the tire structure 30 fails, the other can be driven to propel the vehicle 10000, or one can be rotated to drive the vehicle 10000 according to the required speed.

[0052] In some embodiments of the present invention, referring to Figures 1-4 The tire structure 30 includes a rim 32, and the power assembly 10 is disposed radially inwardly of the rim 32. In this way, the power assembly 10 can be integrated into the hollow space on one side of the rim 32, thereby improving the compactness of the overall structure, eliminating the need for additional space, and not affecting the land formation of the vehicle 10000.

[0053] In some embodiments of the present invention, the first rotor 12 and the second rotor 13 are coaxially arranged and located between the stator 11 and the rim 32 .

[0054] The coaxial arrangement of the first rotor 12 and the second rotor 13 improves the compactness of the overall structure of the power assembly 10. The first rotor 12 and the second rotor 13 are arranged between the stator 11 and the rim 32, which increases the radial rotation path, improves fluid efficiency, and enhances propulsion efficiency.

[0055] In some embodiments, the first rotor 12 and the second rotor 13 may also be disposed on a side of the stator 11 away from the rim 32 .

[0056] In some embodiments, the first rotor 12 is rotatably connected to the rim 32 of the tire structure 30. Connecting the first rotor 12 to the rim 32 provides the first rotor 12 with a fulcrum for movement. The first rotor 12 and the rim 32 are rotatably connected. In this way, the rim 32 not only provides a fulcrum for the first rotor 12, but also allows the first rotor 12 to rotate under the drive of the stator 11, thereby driving the propeller structure 20 connected thereto to rotate.

[0057] In some embodiments of the present invention, referring to Figure 3 and Figure 4 , the propeller structure 20 and the first rotor 12 are integrally formed; or, the propeller structure 20 and the first rotor 12 are fixedly connected.

[0058] The propeller structure 20 is integrally formed with or fixedly connected to the first rotor 12 so that the propeller structure can rotate along with the rotation of the first rotor 12 .

[0059] Specifically, the propeller structure 20 and the first rotor 12 can be welded or fixedly connected via a detachable structure, such as a threaded connection, a snap connection, etc.

[0060] In some embodiments of the present invention, referring to Figure 2-Figure 4 The tire structure 30 further includes a spoke 33, which is paddle-shaped.

[0061] The spokes 33 are designed to be paddle-shaped, and the spokes 33 and the rim 32 form a propeller, which facilitates driving the vehicle 10000 on water.

[0062] In some embodiments of the present invention, the rotation direction of the blades of the propeller structure 20 is opposite to the rotation direction of the blades of the spokes 33 .

[0063] The rotation direction of the propeller structure 20 blades is set to be opposite to the rotation direction of the blades of the spokes 33. In this way, when the propeller structure 20 and the tire rotate at the same time, the reaction torques of the propeller structure 20 blades and the tire blades are opposite in the circumferential direction and can offset each other, thereby reducing the influence of the reaction torque of a single set of blades on the machine base, which is beneficial to the stability of the vehicle 10000 running on water, and can better eliminate or reduce the influence of the spiral water flow on the water navigation and steering device of the vehicle 10000, thereby ensuring the normal navigation of the vehicle 10000.

[0064] In some embodiments, the rotation direction of the blades of the propeller structure 20 and the rotation direction of the blades of the spokes 33 may also be the same.

[0065] In some embodiments of the present invention, referring to Figure 3 and Figure 4 The power assembly 10 further includes a stator bracket 14 , and the stator 11 is connected to the stator bracket 14 in the radial direction of the tire structure 30 .

[0066] The stator bracket 14 is provided to facilitate installation of the stator 11. The stator 11 is connected to the stator bracket 14 along the radial direction of the tire structure 30, which can fully utilize the radial space of the tire and improve the compactness of the structure.

The first rotor bracket 15 is connected to the rim 32 via a bearing, allowing the first rotor bracket 15 and the rim 32 to be rotatably connected. In this way, the first rotor 12 is rotatably connected to the rim 32. The second rotor bracket 16 is connected to the rim 32, thereby connecting the second rotor 13 to the rim 32.

[0070] The first rotor 12 and the first rotor bracket 15 can be fixedly connected, such as by welding, or can be detachably connected, such as by threaded connection, snap connection, etc.

[0071] The second rotor 13 and the second rotor bracket 16 may be fixedly connected, for example, by welding, or detachably connected, for example, by threaded connection, snap connection, etc.

[0073] In some embodiments, the first rotor 12 and the rim 32 may be rotatably connected via a connecting member, such as a rotating shaft, a bearing, etc.; or may be rotatably connected via a sliding groove, etc.

[0074] In some embodiments, reference Figure 1 and Figure 2 The second rotor bracket 16 is connected to the rim 32 through a first detachable component 40, one end of the spoke 33 is connected to the rim 32, and the other end is connected to the stator 11 through a second detachable component.

[0075] The second rotor support 16 and the rim 32, and the spokes 33 and the stator 11 are detachably connected, so that the tire structure 30, the second rotor support 16 and the stator 11 can be easily installed and removed, and maintenance is facilitated.

[0076] In some embodiments, the stator 11 and the wheel hub 31 are detachably connected, which not only facilitates maintenance, but also allows the drive device 100 to be separated from the tire structure 30. When the tire structure 30 fails, the tire structure 30 can be replaced without affecting the coordinated use of the drive device 100 and the tire structure 30.

[0077] In some embodiments, reference Figure 2 The first detachable component 40 includes a first connecting member 41 and a first mounting member 42. The first connecting member 41 is fixedly connected to the rim 32. The first connecting member 41 is provided with a first connecting hole.

When traveling in water, the drive device 100 is rotated to below the chassis of the vehicle body 2000 to drive the vehicle 10000 to travel in the water.

[0100] Specifically, refer to Figure 5 and Figure 6 The tire structure 30 has a first position and a second position.
