[0032] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present utility model will be described in detail below.

[0033] Reference will be made below to Figures 1 - 5 describe a spare tire 10 according to an embodiment of the present utility model, which is applied to a vehicle. For example, a rear door.

[0034] As Figures 1 - 3 shown, the spare tire 10 according to the present utility model includes: a tire assembly 11, a first driving member 12, and a propeller 13. The first driving member 12 includes: a stator 121, a first rotor 122, and a second rotor 123. The second rotor 123 is connected to the tire assembly 11, and the propeller 13 is connected to the first rotor 122. Wherein, the first rotor 122 and the stator 121 form a rotational movement of the first rotor 122 along the central axis of the stator 121; the second rotor 123 and the stator 121 form a linear movement of the second rotor 123 along the central axis of the stator 121; the second rotor 123 can approach the first rotor 122, so that the first rotor 122 and the second rotor 123 perform a rotational movement along the central axis of the stator 121.

[0035] It can be understood that the tire assembly 11, the first driving member 12, and the propeller 13 constitute the main structure of the spare tire 10, and the stator 121, the first rotor 122, and the second rotor 123 constitute the main structure of the first driving member 12. The second rotor 123 is connected to the tire assembly 11, so that the movement of the second rotor 123 can drive the rotation of the tire assembly 11. The propeller 13 is connected to the first rotor 122. Such a setting can not only enable the propeller 13 to change the water flow, but also enable the propeller 13 to support the first rotor 122, thereby ensuring the performance of the first rotor 122 and extending the service life of the first rotor 122.

[0036] Among them, the stator 121, the first rotor 122, and the second rotor 123 are arranged in a hollow manner. Such a setting can allow water flow to pass through the first driving member 12, thereby facilitating the realization of the waterborne driving function of the spare tire 10, and can also make the layout space of the first driving member 12 compact, thereby facilitating the installation and disassembly of the first driving member 12.

[0037] In addition, the first rotor 122 and the stator 121 form a rotational movement of the first rotor 122 along the central axis of the stator 121. Such a setting can enable the first rotor 122 to rotate around the central axis of the stator 121. Thus, when the spare tire 10 realizes the waterborne driving function, the first rotor 122 drives the propeller 13 to rotate, and the propeller 13 controls the direction of the water flow, thereby improving the driving speed and flexibility of the vehicle on water.

[0038] In addition, the second rotor 123 and the stator 121 form a linear motion of the second rotor 123 along the central axis of the stator 121. Such a setting enables the second rotor 123 to move along the central axis of the stator 121, so that the second rotor 123 can approach or move away from the first rotor 122. When the vehicle realizes the enhanced land driving function of the spare tire 10, the second rotor 123 approaches the first rotor 122 and is connected. The first rotor 122 and the second rotor 123 jointly rotate along the central axis of the stator 121, thereby enhancing the flexibility of the vehicle on land and further improving the auxiliary functions of the vehicle in different modes.

[0039] Thus, by rotating the first rotor 122 along the central axis of the stator 121, the first rotor 122 is connected to the propeller 13. Such a setting can realize the water driving function of the spare tire 10, as well as the linear motion of the second rotor 123 along the central axis of the stator 121 and the rotational motion of the first rotor 122 and the second rotor 123 along the central axis of the stator 121. The second rotor 123 is connected to the tire assembly 11. When the second rotor 123 moves linearly and approaches the first rotor 122, the first rotor 122 and the second rotor 123 move together. Such a setting enables the propeller 13 and the tire assembly 11 to move together, thereby realizing the function of the spare tire 10 to enhance the land driving of the vehicle, improving the performance of the spare tire 10, enhancing the integration degree of the spare tire 10, and further realizing the free switching of different modes of the vehicle.

[0040] Among them, as Figure 2 and Figure 3 shown, the stator 121 is arranged inside the tire assembly 11, and the first rotor 122 and the second rotor 123 are spaced apart and penetrate through the stator 121 along the thickness direction of the tire assembly 11.

[0041] It can be understood that the stator 121 is located inside the tire assembly 11, and the first rotor 122 and the second rotor 123 penetrate through the stator 121, so that the first rotor 122 and the second rotor 123 can both rotate around the central axis of the stator 121, and the stator 121 is in contact with the inner wall of the tire assembly 11. Such a setting enables the first driving member 12 to only occupy the inner peripheral space of the tire assembly 11, and enables the tire assembly 11 to protect the first driving member 12, thereby ensuring the performance of the first driving member 12, extending the service life of the first driving member 12, saving the vehicle space occupied by the spare tire 10, and further enhancing the integration degree of the spare tire 10.

[0042] In addition, as Figure 1 and Figure 2As shown, the tire assembly 11 includes: a tire body 111 and a spoke 112. The spokes 112 are arranged at intervals on the inner side of the tire body 111, and the stator 121 is arranged on the inner circumference of the spoke 112. That is to say, the tire body 111 and the spoke 112 constitute the main structure of the tire assembly 11. The tire body 111 is the main part of the tire assembly 11, so that the tire body 111 mainly plays a role in supporting and bearing loads, and the spoke 112 mainly plays a supporting role, so as to support the tire body 111, and further make the tire body 111 more stable. The stator 121 fits with the inner circumference of the spoke 112. Such a setting can make the first driving member 12 only occupy the inner circumference space of the tire assembly 11, and can also make the tire assembly 11 protect the first driving member 12, so as to ensure the performance of the first driving member 12, extend the service life of the first driving member 12, save the space of the spare tire 10 occupied by the whole vehicle, and further improve the integration degree of the spare tire 10.

[0043] In addition, as Figure 2 and Figure 3 shown, the first rotor 122 and the propeller 13 are arranged inside the spoke 112 and rotate along the central axis of the stator 121. It can be understood that the first rotor 122 and the propeller 13 are located inside the spoke 112. Such a setting can make the first rotor 122 and the propeller 13 only occupy the inner circumference space of the spoke 112, and can also make the spoke 112 protect the first rotor 122 and the propeller 13, so as to ensure the performance of the first driving member 12, extend the service life of the first driving member 12, and the first rotor 122 and the propeller 13 can rotate along the central axis of the stator 121. Such a setting can make the first rotor 122 rotate around the central axis of the stator 121. When the spare tire 10 realizes the function of driving on water, the first rotor 122 drives the propeller 13 to rotate, and the propeller 13 controls the direction of the water flow, so as to improve the driving speed and flexibility of the vehicle on water.

[0044] In addition, as Figure 3 shown, the stator 121 forms a first magnetic field 14 and a second magnetic field 15 in the spoke 112. The first magnetic field 14 and the second magnetic field 15 are spaced apart and have different directions. That is to say, the stator 121 forms two magnetic fields in the spoke 112. The two magnetic fields are spaced along the thickness direction of the spoke 112, forming the first magnetic field 14 and the second magnetic field 15, and the directions of the first magnetic field 14 and the second magnetic field 15 are different. Such a setting can make the first magnetic field 14 and the second magnetic field 15 not interfere with each other, so as to make the first magnetic field 14 and the second magnetic field 15 control the independent rotation or common rotation of the first rotor 122 and the second rotor 123, and further facilitate the free switching of different modes of the vehicle.

[0045] Among them, as Figure 3As shown, the first rotor 122 and the propeller 13 are located in the first magnetic field 14, and the first magnetic field 14 enables the first rotor 122 and the propeller 13 to rotate along the central axis of the stator 121; the second rotor 123 is located in the second magnetic field 15, and the second magnetic field 15 enables the second rotor 123 to move linearly along the central axis of the stator 121, and the second rotor 123 is close to the first rotor 122.

[0046] It can be understood that the first rotor 122 and the propeller 13 are located in the first magnetic field 14, and the first magnetic field 14 can enable the first rotor 122 and the propeller 13 to rotate along the central axis of the stator 121, so that the spare tire 10 can realize the function of traveling on water, and the propeller 13 can control the direction of water flow, thereby improving the traveling speed and flexibility of the vehicle on water. The second rotor 123 is located in the second magnetic field 15, and the directions of the first magnetic field 14 and the second magnetic field 15 are different, so that the second rotor 123 can gradually approach the first rotor 122, and the first rotor 122 and the second rotor 123 rotate together along the central axis of the stator 121, thereby enhancing the flexibility of the vehicle on land and realizing the free switching of different modes of the vehicle.

[0047] In particular, as Figure 2 and Figure 3 shown, the first rotor 122 and the propeller 13 are integrally formed or the first rotor 122 and the propeller 13 are fixedly connected. Such a setting not only facilitates the installation and disassembly of the first rotor 122 and the propeller 13, but also enables the first rotor 122 and the propeller 13 to rotate together, so that the spare tire 10 can realize the function of traveling on water, and the propeller 13 can control the direction of water flow, thereby improving the traveling speed and flexibility of the vehicle on water.

[0048] According to the installation assembly 100 of the spare tire of the present utility model, it includes: the spare tire 10 of the above embodiment. By rotating the first rotor 122 along the central axis of the stator 121, and the first rotor 122 is connected to the propeller 13, such a setting can realize the function of the spare tire 10 traveling on water, and the second rotor 123 moves linearly along the central axis of the stator 121 and the first rotor 122 and the second rotor 123 rotate along the central axis of the stator 121. The second rotor 123 is connected to the tire assembly 11. When the second rotor 123 moves linearly and approaches the first rotor 122, the first rotor 122 and the second rotor 123 move together. Such a setting can enable the propeller 13 and the tire assembly 11 to move together, thereby realizing the function of the spare tire 10 to enhance the land traveling of the vehicle, improving the performance of the spare tire 10, and enhancing the integration degree of the spare tire 10, and realizing the free switching of different modes of the vehicle. The installation assembly is used to install the spare tire 10 of the vehicle on the vehicle.

[0049] In addition, as Figure 1 andFigure 2 As shown, the mounting assembly 100 of the spare tire further includes: a mounting frame 20 and a swing arm 30. One end of the swing arm 30 is rotatably arranged on the mounting frame 20, and the other end of the swing arm 30 is connected to the first driving member 12. It can be understood that the mounting frame 20 mainly plays a role in mounting, thereby improving the overall structural strength of the mounting assembly 100 of the spare tire. The swing arm 30 mainly plays a role in transmission, so that the spare tire 10 can be flipped and retracted, thus facilitating the use and placement of the spare tire 10. One end of the swing arm 302 is rotatably arranged on the mounting frame 20, that is to say, one end of the swing arm 30 can rotate relative to the mounting frame 20. Also, the other end of the swing arm 30 is connected to the first driving member 12. In this way, when one end of the swing arm 30 rotates relative to the mounting frame 20, the other end of the swing arm 30 will drive the first driving member 12 to rotate, and thus the inclination angles of the first driving member 12 and the tire assembly 11 can be adjusted.

[0050] Furthermore, as Figure 1 and Figure 2 shown, the mounting assembly 100 of the spare tire further includes: a second driving member 40. The rotating shaft of the second driving member 40 passes through the mounting frame 20, and the rotating shaft of the second driving member 40 is drivingly connected to the swing arm 30. That is to say, the second driving member 40 mainly plays a driving role. The rotating shaft of the second driving member 40 passes through the mounting frame 20, and the rotating shaft of the second driving member 40 is drivingly connected to the swing arm 30, so that the second driving member 40 can drive the swing arm 30 to rotate, thus facilitating the use and placement of the spare tire 10.

[0051] In addition, the mounting assembly 100 of the spare tire further includes a connecting line. A hollow cavity is formed inside the swing arm 30. The connecting line passes through the hollow cavity, and the connecting line is electrically connected to the first driving member 12 and the second driving member 40 respectively. Among them, the connecting line is mainly used for transmitting signals. The hollow cavity mainly plays a role in passing through and mounting. Passing the connecting line through the hollow cavity, that is to say, part of the connecting line is installed inside the hollow cavity, which can save installation space and can protect the connecting line by using the hollow cavity. In addition, the connecting line is electrically connected to the first driving member 12 and the second driving member 40 respectively, so that external signals can be respectively transmitted to the first driving member 12 and the second driving member 40, facilitating the control of the first driving member 12 and the second driving member 40.

[0052] Specifically, as Figure 4 and Figure 5 shown, when the vehicle switches to the waterborne driving mode: the swing arm 30 flips the mounting frame 20 and the spare tire 10 to a specified direction, and the first driving member 12 starts to work. At this time, the first rotor 122 works and the second rotor 123 stops. The propeller 13 can change the water flow, so that the vehicle can travel along a predetermined driving direction, thereby increasing the waterborne driving efficiency of the vehicle.

[0053] When the vehicle switches to the land driving mode: In case of an emergency, the swing arm 30 flips the mounting bracket 20 and the spare tire 10 to a specified direction, and the driver and passengers remove the spare tire 10 and install it at the position of the wheel that needs to be replaced, so as to ensure the normal driving of the vehicle. When the vehicle needs to turn in a narrow space, the swing arm 30 flips the mounting bracket 20 and the spare tire 10 to a specified direction, and the first driving member 12 starts to work. At this time, the first rotor 122 and the second rotor 123 work, that is, the second rotor 123 gradually approaches the first rotor 122 under the action of the first magnetic field 14 and the second magnetic field 15. The first rotor 122 and the second rotor 123 move together to drive the tire body 111, so as to realize the turning of the vehicle in a narrow space.

[0054] The vehicle according to the present utility model includes: a rear door, a chassis, and the mounting assembly 100 of the spare tire in the above embodiment. The mounting assembly is arranged behind the rear door or under the chassis. Arranging the mounting assembly behind the rear door can fix some structures of the mounting assembly, making the setting of the mounting assembly more reliable and stable, so that the mounting assembly can work better. Moreover, by arranging the mounting assembly of the spare tire 10 on the rear door, the original mounting space of the spare tire 10 body is utilized. Therefore, no additional design space is added, and the driving of the vehicle 3 on land is not affected.

[0055] Among them, as Figure 4 and Figure 5 shown, the second driving member 40 drives the swing arm 30 to flip to an approximately vertical position, and the spare tire 10 contacts the ground. The first driving member 12 drives the tire assembly 11, so that the vehicle can turn in place with the front wheels as the rotation points. That is to say, when the vehicle switches to the land driving mode, the second driving member 40 drives the swing arm 30 to flip to an approximately vertical position, the first driving member 12 drives the tire assembly 11, the second rotor 123 gradually approaches the first rotor 122 under the action of the first magnetic field 14 and the second magnetic field 15, and the first rotor 122 and the second rotor 123 move together to drive the tire body 111, so that the vehicle can turn in place with the front wheels as the rotation points, and further the turning of the vehicle in a narrow space can be realized.

[0056] As an alternative embodiment, the mounting assembly 100 of the spare tire can also be mounted on the chassis.

[0057] In addition, the vehicle further includes: a controller. The mounting assembly further includes: a second driving member 40. The first driving member 12 and the second driving member 40 are respectively electrically connected to the controller. Among them, the controller mainly plays a role in control. Specifically, the controller can analyze and judge the received information, and control the first driving member 12 and the second driving member 40 to work correspondingly according to the analysis and judgment results. In this way, it is convenient to control the first driving member 12 and the second driving member 40, and the effectiveness and reliability of the mounting assembly work can be improved.

[0058] In addition, since the tire body 111 is filled with gas inside and its overall structure is similar to a floating box, the buoyancy of the vehicle can be improved.

[0059] It should be noted that when driving on land, the tire assembly 11 rotates around the output shaft of the second driving member 40 through the swing arm 30 to fit the rear door. This can not only prevent the tire body 111 from dragging on the ground and interfering with the normal driving of the vehicle on land, but also protect the first driving member 12, and does not affect the normal access of the tire body 111.
