Automobile wheels are provided with multiple spokes for connecting and supporting the inner connecting ring and the outer connecting ring. However, the spoke structures and sizes of existing automobile wheels are the same. Any spoke passing through the same position has the same reflection angle for light and the same guiding direction for the flowing gas. During the high-speed rotation of the wheel, the rotating spokes form a nearly complete surface, which not only has an unsightly visual effect, but also has poor ventilation and heat dissipation effects, and is prone to noise. Moreover, this type of wheel is heavy, which increases the weight and cost of the entire vehicle, and reduces power and economy. Summary of the invention
