[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0073] According to the first aspect of this application, referring to Figure 1 , Figure 2 and Figure 5 This application provides a wheel 100, including a body 110 and a movable part 120.

[0074] Specifically, the body 110 includes a hub 111, a rim 112, and spokes 113. The hub 111 is used to connect the axle, suspension, etc., and provides central support for the wheel 100. The rim 112 is used to mount the tire. The spokes 113 connect the hub 111 and the rim 112 and provide support to prevent the wheel 100 from deforming. The body 110 has internal space for mounting heat-generating components such as brakes or the hub 111 motor.

[0075] The movable component 120 is used to form a guide channel for gas flow with the body 110. During the movement of the wheel 100, it can actively guide the gas into the internal space of the body 110 and exchange heat with the heat-generating components installed inside the body 110.

[0076] The movable component 120 is movably connected to the body 110 so that the movable component 120 has different angles with the central axis C1 of the body 110 at different positions. It can be understood that the central axis C1 of the body 110 can be the rotation center of the wheel 100 during operation. The angle between the movable component 120 and the central axis C1 can be adjusted according to actual needs, thereby adjusting the ventilation volume and guiding direction of the guide channel to meet different heat dissipation requirements.

[0077] Through the above technical solution, by setting the movable component 120, it can form a guide channel with the main body 110 to actively guide the gas, increase the ventilation of the wheel 100 and improve the heat dissipation performance; and the movable component 120 is movably connected to the main body 110 and has different angles with the central axis C1 of the main body 110 at different positions, which can adjust the guiding capacity of the guide channel, thereby making it suitable for some scenarios with large heat dissipation requirements; for example, there is a risk of brake overheating when braking on a long downhill slope at high speed, and effective heat dissipation can be achieved by actively guiding the gas through the movable component 120.

[0078] In some embodiments, the angle between the movable member 120 and the central axis C1 of the wheel 100 ranges from 0° to 90°.

[0079] It is understandable that by limiting the range of the included angle, the guide channel formed by the moving part 120 and the body 110 can be adjusted from the maximum ventilation volume to the minimum ventilation volume, or from the maximum ventilation volume to complete closure.

[0080] For example, the movable part 120 can be rotated to a position perpendicular or parallel to the central axis C1.

[0081] As a specific plan, refer to Figure 5 The main body 110 has a vent 110a. The vent 110a communicates with the internal space of the main body 110, meaning that the internal space of the main body 110 is connected to the external environment through the vent 110a. The vent 110a increases airflow between the internal space and the external environment; however, it can also increase the wind resistance of the wheel 100. It is easy to understand that the larger the opening area of ​​the vent 110a, the greater the ventilation volume, and consequently, the greater the wind resistance.

[0082] The opening area here can be the projected area of ​​the wall surface forming the vent 110a along the central axis C1.

[0083] In some embodiments, refer to Figure 1 At least a portion of the movable member 120 is located within the vent 110a. That is, the movable member 120 and the vent 110a are at least partially coincident in the circumferential and / or axial direction of the central axis C1, and the guide channel may be a gap formed between the movable member 120 and the wall of the body 110 of the vent 110a.

[0084] By employing this scheme, at least a portion of the movable part 120 is located within the vent 110a, allowing the movable part 120 to block a portion of the vent 110a. This adjusts the opening area of ​​the vent 110a, thereby adjusting the ventilation volume and wind resistance of the vent 110a and balancing the air resistance and heat dissipation performance of the wheel 100.

[0085] In some embodiments, the axial projected area of ​​the movable member 120 is less than or equal to the axial projected area of ​​the vent 110a.

[0086] It is understood that, since the structure of the main body 110 is fixed, the projected area of ​​the vent 110a in the axial direction can be considered constant; when the movable part 120 moves to different positions relative to the main body 110, it has different projected areas in the axial direction. By limiting the projected area of ​​the movable part 120 in the axial direction to be less than or equal to the projected area of ​​the vent 110a in the axial direction, it is possible to avoid collision and interference between the movable part 120 and the main body 110 during movement.

[0087] For example, the closer the axial projected area of ​​the movable member 120 is to the axial projected area of ​​the vent 110a, the smaller the opening area of ​​the vent 110a. When the axial projected area of ​​the movable member 120 is equal to the axial projected area of ​​the vent 110a, the movable member 120 can completely close the vent 110a.

[0088] In some embodiments, refer to Figure 1 and Figure 2 The movable part 120 is rotatably connected to the body 110 so that the movable part 120 and the vent 110a have different coupling areas.

[0089] The coupling area between the movable part 120 and the vent 110a can be understood as the area of ​​the overlapping part of the projection of the movable part 120 in the axial direction and the projection of the window in the axial direction.

[0090] By adopting this scheme, the coupling area can be continuously adjusted through the rotatable connection between the movable part 120 and the main body 110, thereby effectively balancing wind resistance and heat dissipation requirements.

[0091] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 The movable component 120 is configured to rotate relative to the body 110 about a rotation axis C2; the rotation axis C2 is perpendicular to the central axis C1.

[0092] It is understandable that the movable part 120 extends radially along the central axis C1, and when it rotates along the rotation axis C2, it can be adjusted to partially extend beyond the body 110 to play a role in drainage.

[0093] In some embodiments, the movable element 120 is configured to have a first guide surface 121 and a second guide surface.

[0094] The first guide surface 121 and the second guide surface are disposed on opposite sides of the movable member 120. The first guide surface 121 is configured to form a first type of flow channel with the body 110 through the vent 110a; the second guide surface is configured to form a second type of flow channel with the body 110 through the vent 110a.

[0095] It is understandable that the guiding flow channel includes at least the first type of flow channel and the second type of flow channel.

[0096] By setting the first guide surface 121 and the second guide surface, airflow can be guided, allowing air to pass more smoothly through the vent 110a.

[0097] In a specific embodiment of this application, the movable member 120 is configured in a fan-shaped form, with a uniform thickness between the first guide surface 121 and the second guide surface. The included angle can be understood as the angle between the first guide surface 121 or the second guide surface and the central axis C1. Based on the effect of the first guide surface 121 and the second guide surface on the air when rotating with the body 110, one of the first guide surface 121 and the second guide surface can serve as a pressure surface, and the other can serve as a suction surface.

[0098] In some embodiments, refer to Figure 5 The hub 111, rim 112 and spokes 113 together form the vent 110a; wherein the first guide surface 121 and the second guide surface are located between the hub 111 and the rim 112.

[0099] In some embodiments, refer to Figure 1 and Figure 2 The wheel 100 further includes a drive assembly 130. The drive assembly 130 is configured to drive the movable component 120. This design allows for active adjustment of the movable component 120, thereby improving air resistance or heat dissipation and reducing overall vehicle energy consumption.

[0100] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4The wheel 100 includes a plurality of movable parts 120. The plurality of movable parts 120 are arranged circumferentially along the central axis C1. Correspondingly, the body 110 is provided with a plurality of vents 110a circumferentially along the central axis C1, and the movable parts 120 correspond one-to-one with the vents 110a.

[0101] The drive assembly 130 includes a transmission member 131. The transmission member 131 is coupled to the plurality of movable members 120 to drive the plurality of movable members 120 to move.

[0102] By adopting this scheme, multiple moving parts 120 are driven to move synchronously through the transmission component 131, so that the multiple moving parts 120 have the same angle with the central axis C1, thereby improving the consistency of air resistance and ventilation volume of the wheel 100 in the circumferential direction.

[0103] In some embodiments, refer to Figure 6 The drive assembly 130 includes a prime mover 132. The prime mover 132 drives the transmission member 131 to rotate around the central axis C1. More specifically, the prime mover 132 may be an electric motor.

[0104] For example, the transmission member 131 has a connecting shaft 131a extending axially for connection with the prime mover 132.

[0105] As an alternative, each moving part can also be driven by an independent motor.

[0106] In some embodiments, refer to Figure 2 and Figure 3 The transmission component 131 includes a transmission part 131b. The transmission part 131b is coupled to the plurality of movable parts 120, and the transmission part 131b is configured as transmission teeth arranged around the central axis C1.

[0107] This design achieves high transmission efficiency and accuracy through the rotational motion of the transmission component 131 and the action of the transmission teeth.

[0108] In some embodiments, refer to Figures 2 to 4 The drive assembly 130 further includes a driven gear 133. The driven gear 133 meshes with the transmission part 131b, and the driven gear 133 is anti-rotatingly connected to the movable member 120. By providing the driven gear 133, the movement of the transmission member 131 along the central axis C1 is converted into the rotation of the movable member 120 along the rotation axis C2.

[0109] Optionally, the meshing method between the driven gear 133 and the transmission part 131b can be a combination of spur gear and helical gear, or a combination of bevel gear, etc.

[0110] As a specific plan, refer to Figure 2 and Figure 3 Both the transmission part 131b and the driven gear 133 are constructed as bevel gears.

[0111] In some embodiments, the transmission member 131 and the driven gear 133 are respectively mounted on the hub 111. This improves the structural compactness. Furthermore, the transmission member 131 and the hub 111 form a rotatable connection, improving the motion stability of the transmission member 131.

[0112] In some embodiments, refer to Figures 2 to 4 The movable component 120 further includes a first connecting portion 122. The first connecting portion 122 is anti-rotatably connected to the driven gear 133; the first connecting portion 122 and / or the driven gear 133 are rotatably connected to the hub 111.

[0113] By adopting this scheme, the first connecting part 122 of the moving part 120 is rotated and supported by the hub 111, thereby improving the stability of the moving part.

[0114] In some embodiments, the rim 112 has a mating groove (not shown). The mating groove is formed on the side of the rim 112 near the hub 111. Specifically, the mating groove is configured as a columnar groove.

[0115] Reference Figure 2 and Figure 4 The movable component 120 further includes a second connecting portion 123. At least a portion of the second connecting portion 123 is embedded in a mating groove and can rotate within the groove, so that the movable component 120 and the rim 112 form a rotatable connection.

[0116] By adopting this scheme, the second connecting part 123 is limited by the mating groove of the rim 112, and the stability of the moving part 120 is further improved when the angular adjustment is combined with the mating of the hub 111 and the first connecting part 122.

[0117] In some embodiments, refer to Figure 2 The wheel 100 further includes a locking assembly. The locking assembly is used to lock the movable member 120 to the body 110 so that the movable member 120 and the central axis C1 of the wheel 100 are maintained at a preset angle.

[0118] Optionally, the locking assembly can cooperate with the transmission member 131 to lock the moving member 120 through the transmission part 131b and the driven gear; or, the locking assembly can directly lock the second connecting part 123 to the rim 112.

[0119] By using this solution, after the movable part 120 is adjusted to the required angle, it is braked and locked to prevent positional displacement during the rotation of the wheel 100.

[0120] For example, the locking component can be implemented by means of a concave-convex fit or contact clamping.

[0121] According to a second aspect of this application, a wheel assembly 100 is provided, which includes the wheel 100 described above and a tire, the tire being mounted on the wheel 100. This wheel assembly 100 possesses all the beneficial effects of the wheel 100 described above, which will not be elaborated further herein.

[0122] According to a third aspect of this application, a vehicle is provided that includes the aforementioned wheel 100, or the aforementioned wheel 100 assembly, and the vehicle has all the beneficial effects of the aforementioned wheel 100, which will not be repeated here.

[0123] The vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific restrictions.

[0124] In some embodiments, refer to Figure 6 The vehicle further includes a controller 200. The controller 200 is electrically connected to the prime mover 132 and is configured to control the operation of the prime mover 132 according to the vehicle's travel speed to adjust the angle between the movable member 120 and the central axis C1 of the wheel 100.

[0125] When the vehicle's speed increases, air resistance increases, and the need to reduce resistance exceeds the need for heat dissipation. The controller 200 sends a signal to the prime mover 132 to control the rotation of the movable part 120, which increases the coupling area between the movable part 120 and the vent 110a. This reduces the gap between the movable part 120 and the inner wall of the vent 110a until the gap disappears, thereby reducing air resistance. When the vehicle's speed decreases, air resistance decreases, and the brake temperature increases. The controller 200 sends a signal to the prime mover 132 to control the rotation of the movable part 120, which reduces the coupling area between the movable part 120 and the vent 110a. This increases the gap between the movable part 120 and the inner wall of the vent 110a, increasing ventilation and improving heat dissipation.

[0126] By adopting this approach, the state of the moving part 120 is adjusted according to the needs of the vehicle under different driving conditions on the road, thereby improving air resistance or heat dissipation performance and reducing the vehicle's energy consumption.

[0127] Optionally, the controller 200 can be a vehicle controller 200 or a standalone controller 200.
