[0003] The utility model with announcement number CN220220268U relates to the field of automotive wheel hub technology and discloses a self-heating wheel hub blade, including a wheel hub body. The end face of the wheel hub body has several equidistant air guide holes for heat dissipation. Several pairs of gas guiding components are detachably connected to the end face of the wheel hub body. Each gas guiding component includes a guide part, a first cutting groove, and a second cutting groove. The guide part is inclined towards the direction of rotation of the wheel hub body, and its concave surface faces the air guide holes and guides the gas into them. During the rotation of the wheel hub body, the concave surface of the guide part impacts the air and guides it. The concave surface of the guide part guides the flowing air to the port of the air guide hole and into it, increasing the heat dissipation effect on the braking system and the wheel hub body itself, preventing brake fade. By setting the guide part through a detachable connection, the original forming process of the wheel hub is retained, allowing for later installation and cost control.

[0004] However, the above-mentioned patents still have the following problems: the bolt installation method is inconvenient for quick installation, the installation time is long, and it is difficult to meet the high-efficiency assembly requirements of automated production lines. The wheel hub is subjected to high-frequency vibration and alternating load during driving. The bolt connection is prone to micro-cracks due to stress concentration.

The following embodiments are used to illustrate this utility model.

[0020] Example 1: Elliptical air vent spokes and novel air guide blades, specifically as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the spoke body 10 is a circular disc. It has a snap-fit ​​structure, including a first snap-fit ​​part and a second snap-fit ​​part. The first snap-fit ​​part includes ten sets of elliptical air guide holes 11 opened on the inner wall of the spoke body 10. The elliptical air guide holes 11 are elliptical in shape. The second snap-fit ​​part includes ten sets of air guide blade bodies 12 disposed on the outside of the spoke body 10. The air guide blade bodies 12 include a first air guide blade 13 and a second air guide blade 14. A set of first clips 15 and a set of second clips 16 are fixedly installed at the bottom of the first air guide blade 13. The first clips 15 and the second clips 16 are respectively snapped onto both sides of the elliptical air guide holes 11. One outer wall of the first clips 15 and the second clips 16 is tightly attached to the inner wall of the spoke body 10. The guide vane is quickly installed into the elliptical air hole using a snap-fit ​​structure. The first clip 16 is snapped into the elliptical air hole 13, and the second clip 17 is pressed and snapped into the elliptical air hole 13, so that one outer wall of the first clip 16 and the second clip 17 is in close contact with the inner wall of the spoke body 10. The second guide vane 15 is snapped into the elliptical air hole 13. The airflow is guided and cooled through the first guide vane 14 and the elliptical air hole 13.

[0021] Based on the above, the structure of the wheel spoke body 10, the elliptical air guide hole 11, the air guide blade body 12, the first air guide blade 13, the second air guide blade 14, the first clip 15 and the second clip 16 replaces the bolt connection method of the air guide blade, which improves the installation efficiency of the air guide blade. The elastic snap-fit ​​structure enables tool-free quick installation and reduces assembly costs.

[0022] Example 2: Based on Example 1, specifically as follows... Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, one side of the outer wall of the first guide vane 13 is fixedly connected to one side of the outer wall of the second guide vane 14, and the second guide vane 14 is arc-shaped.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the concave bending angle of the second guide vane 14 is less than 55 degrees, and the first guide vane 13 corresponds one-to-one with the corresponding elliptical guide hole 11. The convex surface of each second guide vane 14 faces the corresponding elliptical guide hole 11.

[0024] Based on the above, the structure of the elliptical air guide hole 11 and the air guide blade body 12 enables the air guide blade to be installed quickly. Through the multi-blade collaborative heat dissipation design, it can adapt to the needs of different vehicle models. The elliptical air guide hole topology optimization design improves the air guide blade's ability to prevent it from falling off, taking into account both strength and lightweight.

[0025] Example 3: Based on Examples 1 and 2, specifically as follows... Figure 1 , Figure 4 and Figure 5 As shown, the first guide vane 13, the second guide vane 14, the first clip 15, and the second clip 16 are made of polymer injection molding. This process is easy to manufacture, easy to install, lightweight, and offers good elasticity and durability.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, the wheel spoke body 10 is made of steel (wheel-specific steel), and its surface is coated with an anti-corrosion coating with a thickness of 10μm~50μm. This multi-layer anti-corrosion coating system improves vehicle energy efficiency and handling, achieving durable protection under all operating conditions.

[0027] Specifically, such as Figure 4 and Figure 5 As shown, the maximum pull-out force of the first clip 15 and the second clip 16 is ≥50N. After 100,000 vibration cycles, the engagement force attenuation rate is ≤15%. In an environment of -40℃ to 120℃, there is no plastic deformation or brittle fracture. This extends the service life of the parts.

[0028] Specifically, such as Figure 1and Figure 3 As shown, the major axis of the elliptical air guide hole 11 forms an angle of 0° to 45° with the radial direction of the wheel spokes. This reduces wind resistance, provides precise airflow guidance, minimizes turbulence losses, improves heat dissipation efficiency, and extends the life of the braking system.

[0029] In summary, the structure of the spoke body 10, the elliptical air guide hole 11, the air guide blade body 12, the first air guide blade 13, the second air guide blade 14, the first clip 15 and the second clip 16 improves the durability of the device, extends its service life, reduces its production cost, enhances its stability, and optimizes its user experience.

Through the snap-fit ​​structure, the air guide blades are quickly installed into the elliptical air vents. The first clip 16 is snapped into the elliptical air guide hole 13, and the second clip 17 is pressed in, so that one side of their outer wall is tightly attached to the inner wall of the spoke body 10. The second air guide blade 15 is then snapped into the elliptical air guide hole 13. In this embodiment, one side of the outer wall of the first guide vane 13 is fixedly connected to one side of the outer wall of the second guide vane 14. The second guide vane 14 is arc-shaped, and the concave bending angle of the second guide vane 14 is less than 55 degrees. The first guide vane 13 corresponds one-to-one with the elliptical air guide hole 11, and the convex surface of the second guide vane 14 faces the elliptical air guide hole 11. The first guide vane 13, the second guide vane 14, the first clip 15, and the second clip 16 are made of high-polymer injection molding, which is easy to produce, easy to install, lightweight, elastic, and durable. The spoke body 10 is made of steel. (Wheel-specific steel), with a 10μm-50μm anti-corrosion coating, improves vehicle energy efficiency and handling, and provides durable protection under all working conditions. The maximum pull-out force of the first clip 15 and the second clip 16 is ≥50N. After 100,000 vibration cycles, the clamping force attenuation rate is ≤15%. It does not undergo plastic deformation or brittle fracture in environments ranging from -40℃ to 120℃, thus extending the service life of parts.
