[0002] As people's material and cultural living standards continue to improve, there are also more and more entertainment devices and methods available for people's leisure and entertainment. Among them, racing games have a relatively wide market, especially among young people.

[0003] Generally, under high-intensity use, racing car braking systems are prone to performance degradation due to heat buildup, and may even experience brake fade, leading to brake system failure. Currently, braking systems dissipate heat through passive cooling methods. For example, this can be achieved by using ventilated discs and air ducts. However, the heat dissipation efficiency of passive cooling cannot meet the high heat dissipation requirements of racing car braking systems. Therefore, improving the heat dissipation efficiency of racing car braking systems is one of the problems that those skilled in the art should solve. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wheel rim that improves the heat dissipation efficiency of the braking system of racing cars, in order to address the above-mentioned deficiencies of the prior art.

[0005] To achieve the above objectives, this utility model provides a wheel rim, comprising:

[0006] A frame;

[0007] A wheel hub, and the frame surrounding the wheel hub; and

[0008] Multiple spokes are connected between the hub and the frame and are arranged circumferentially along the hub. Each spoke has two opposing arc-shaped side edges, and the two opposite ends of the two arc-shaped side edges are respectively connected to the hub and the frame. The hub and the multiple spokes together form a fan-shaped shape.

[0009] The aforementioned wheel rim includes an outer frame and an inner frame. The outer frame surrounds and is connected to the inner frame. The inner frame surrounds the wheel hub, and the two arc-shaped side edges are connected to the inner frame.

[0017] The aforementioned wheel rim, wherein the plurality of spokes are made of aluminum alloy or titanium alloy.

[0018] The beneficial effects of this utility model are as follows:

[0019] The hub and spokes of this invention are both fan-shaped, allowing the rotating wheel rim to directly act as a fan to cool the racing car's braking system during operation. In other words, the wheel rim can function as an active cooling structure.

[0046] The structural and working principles of the present invention will be described in detail below with reference to the accompanying drawings:

[0047] Please see Figures 1 to 3 . Figure 1 This is a perspective view of a wheel frame omitting a temperature sensor according to an embodiment of the present invention. Figure 2 for Figure 1 Another 3D diagram of the wheel rim, Figure 3 for Figure 1 An exploded view of the wheel rim.

[0048] The wheel rim 10 of this embodiment is applied, for example, to a racing car or other mobile vehicle; that is, the wheel rim 10 of this embodiment is mounted, for example, on the body shell of a racing car (not shown). The wheel rim 10 is used to mount a racing car tire (not shown) and includes a frame 20, a hub 30, and a plurality of spokes 40. The surface of the wheel rim 10 is, for example, anodized or has a high-temperature resistant coating to improve the corrosion resistance of the wheel rim 10. In this way, the service life of the wheel rim 10 can be extended.

[0049] The frame 20 includes an outer frame 21 and an inner frame 22. The outer frame 21 surrounds and is connected to the inner frame 22. Specifically, the inner frame 22 is fixed to the outer frame 21, for example, by riveting or screwing. That is, the rim 10 is a two-piece rim 10. The inner frame 22 surrounds the hub 30.

[0050] Please refer to the following: Figure 4 and Figure 5 . Figure 4 for Figure 1 A plan view of the wheel rim. Figure 5 For along Figure 4 A cross-sectional view of the frame with section 5-5.

[0051] These spokes 40 connect the hub 30 and the inner frame 22 of the frame 20 to support the structure of the frame 10, and are arranged circumferentially along the hub 30. Each spoke 40 has two opposing arc-shaped side edges 41. The opposite ends of the two arc-shaped side edges 41 are respectively connected to the hub 30 and the inner frame 22. The two arc-shaped side edges 41 have the same curvature direction, for example. In this way, the hub 30 and these spokes 40 can be made to form a fan blade shape, so that the frame 10 can be an active cooling structure during rotation. In this way, the hub 30 of the frame 10 is the hub 30 of the fan blade, and these spokes 40 of the frame 10 are the blades of the fan blade.

[0052] When the race car is moving and the wheel rim 10 rotates, the fan-shaped wheel hub 30 and the spokes 40 are used to create a hot airflow around the race car's braking system, and the hot airflow is discharged to cool the race car's braking system.

[0053] In this embodiment, the angles of these spokes 40 correspond, for example, to the rotation trajectory of the frame 20, so that the spokes 40 and the rotation trajectory of the frame 20 are synchronized. In this way, the exhaust airflow can be more smoothly discharged from the race car body, thereby meeting the heat dissipation requirements of the race car's braking system.

[0054] In this embodiment, the hub 30 and the spokes 40 are made of materials such as aluminum alloy or titanium alloy to meet the requirements of high thermal conductivity, lightweight, and durability, but are not limited thereto. Furthermore, the hub 30 and the spokes 40 are manufactured, for example, using computer numerical control (CNC) to improve the structural strength and geometric accuracy of the hub 30 and the spokes 40. Additionally, the spokes 40, the inner frame 22, and the hub 30 are, for example, integrally formed to improve the structural strength of the spokes 40, the inner frame 22, and the hub 30 and reduce contact resistance with the exhaust airflow.

[0055] In this embodiment, the outer frame 21 may further include a first gradually expanding portion 211, a second gradually expanding portion 212, and a connecting portion 213. The first gradually expanding portion 211 and the second gradually expanding portion 212 are connected to opposite sides of the connecting portion 213, and the diameters of the first gradually expanding portion 211 and the second gradually expanding portion 212 increase outward from the side connected to the connecting portion 213.

[0056] In detail, the outer frame 21 may also have an airflow channel 214. The airflow channel 214 has an air inlet section 2141, an air outlet section 2142, and a connecting section 2143. The air inlet section 2141 is located in the first expanding section 211. The air outlet section 2142 is located in the second expanding section 212. The connecting section 2143 is located in the connecting section 213. The air inlet section 2141 and the air outlet section 2142 are respectively connected to opposite sides of the connecting section 2143. The air inlet section 2141 is positioned closer to the racing car's braking system than the air outlet section 2142. The wheel hub 30, the spokes 40, and the inner frame 22 are located in the air outlet section 2142, and the inner frame 22 is connected to the second expanding section 212. The maximum diameters R1 and R2 of the air inlet section 2141 and the air outlet section 2142 are, for example, larger than the diameter R3 of the connecting section 2143.

[0057] In this embodiment, the wheel rim 10 may also include a temperature sensor 50. The temperature sensor 50 is disposed on the frame 20. For example, the temperature sensor 50 is disposed on the first expanding portion 211 of the outer frame 21 of the frame 20, but is not limited thereto. By providing the temperature sensor 50, the braking temperature of the racing car's braking system can be monitored.

[0058] In this embodiment, since the wheel hub 30 and the spokes 40 together form a fan-shaped structure, the rotating wheel rim 10 can directly act as a fan to dissipate heat from the racing car's braking system while the car is in motion. In other words, the wheel rim 10 can directly function as an active cooling structure. Compared to passive cooling methods such as ventilator discs and air ducts, the active cooling of the wheel rim 10 improves the heat dissipation efficiency of the racing car's braking system. This enhances the heat dissipation efficiency of the racing car's braking system.

[0059] Furthermore, since the rotating wheel rim 10 can directly act as a fan to generate exhaust airflow, there is no need to install additional cooling devices or drive mechanisms to operate the cooling devices. This reduces the manufacturing cost of the race car and saves energy consumption.

[0060] Please refer to the following: Figure 6 . Figure 6 For airflow Figure 5 A cross-sectional view of the wheel rim. In this embodiment, when the race car is moving and the wheel rim 10 rotates, the exhaust airflow formed by the hot air around the race car's braking system flows from the air intake section 2141 into the airflow channel 214 in direction A. Then, the exhaust airflow flows in direction B within the airflow channel 214 towards the air outlet section 2142. Next, the exhaust airflow exits from the air outlet section 2142 through the spokes 40 in direction C and is discharged outside the race car body, while cool air from outside the race car body replenishes the space around the race car's braking system for the next cooling cycle. In this way, the race car's braking system can be cooled simultaneously while the race car is in motion.

[0061] In this embodiment, the wheel rim 10 is used in a racing car, but is not limited thereto. In other embodiments, the wheel rim can also be used in other high-performance mobile vehicles or industrial applications requiring high heat dissipation efficiency.

[0062] In this embodiment, the frame 20 includes an outer frame 21 and an inner frame 22, making the rim 10 a two-piece rim 10, but not limited thereto. In other embodiments, the frame may also be integrally formed, making the rim a one-piece rim, or the outer frame, inner frame, and spokes may be, for example, separate components, making the rim a three-piece rim.

[0063] In this embodiment, the inner frame 22 is fixed to the outer frame 21 by riveting or screwing, but this is not a limitation. In other embodiments, the inner frame may also be fixed to the outer frame by other means.

[0064] In this embodiment, the two arc-shaped side edges 41 bend in the same direction, but this is not a limitation. In other embodiments, the two arc-shaped side edges may be bend in different directions.

[0065] According to the wheel rim described in the above embodiment, since the hub and spokes together form a fan-like shape, the rotating wheel rim can directly act as a fan to dissipate heat from the racing car's braking system during operation. In other words, the wheel rim can directly function as an active cooling structure. Compared to passive cooling methods such as ventilated discs and air ducts, the wheel rim, as an active cooling system, improves the heat dissipation efficiency of the racing car's braking system. This, in turn, enhances the heat dissipation efficiency of the racing car's braking system.

[0066] Furthermore, since the rotating wheel rims can directly act as fans to generate exhaust airflow, there is no need to install additional cooling devices or drive mechanisms to operate them. This reduces the manufacturing cost of the race car and saves energy consumption.

[0067] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
