Embodiment 1

[0039] With the tightening of fuel consumption requirements and the pursuit of battery life for electric vehicles, the research and development of low-drag components is becoming more and more important, and the design of low-drag rims is also one of them. The existing low-drag rims are all fixed structure to reduce wind resistance, the authorized announcement number is CN203611638U, and the patent name is a car wheel hub that reduces the wind resistance coefficient, such as Figure 6 As shown in this patent, the spokes are eccentrically arranged, and arc surfaces with different angles are set on the outside of the spokes, and the arc surfaces with smaller angles face the direction of the car to reduce wind resistance, and the wind pressure on the side with larger angles The small size drives the air to flow towards the inner brake disc; the spoke design is eccentric to one side, so that when the spoke cuts the air, the air flows along the spoke to the outside, and the gap outsi...

Embodiment 2

[0069] Embodiment 2 is a preferred embodiment of embodiment 1

[0070] The preferred feature of this embodiment and Embodiment 1 is that the elastic member 5 is a telescopic spring, and the fixing method of the telescopic spring is also consistent with Embodiment 1, and its working principle and beneficial effects are also the same as those of the above-mentioned embodiment. Basically the same, so I won't go into details here.

Embodiment 3

[0072] Through the rim assembly for automatically adjusting wind resistance provided by the above-mentioned embodiment, but lacking an application body, this embodiment provides a vehicle, which has the above-mentioned rim assembly for automatically adjusting wind resistance, and is installed on the vehicle On all the rims of the car, the function of automatically adjusting the wind resistance can be realized through this setting, but it needs to be designed according to the specific model.

Abstract

The invention discloses a rim assembly for automatically adjusting wind resistance, which includes a rim and spokes, the spokes are fixed on the rim, and rim windows are formed between the spokes, and the rim assembly also includes venetian blinds; the spokes An accommodating groove is provided along the side for accommodating the venetian blind; a groove is provided on the side of the rim close to the window of the rim, and the elastic member is connected to the venetian blind to rotate along the groove for shielding or Partially blocking the rim window, the present invention also provides a vehicle, the vehicle has the rim provided above, the present invention can realize the adjustment of the drag coefficient according to different vehicle speeds, and at the same time ensure the heat dissipation requirements of the brake.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a wheel rim assembly and a vehicle for automatically adjusting wind resistance. Background technique [0002] With the continuous development and progress of science and technology, the competition in the modern automobile industry is becoming more and more fierce. The production capacity of the industry is far greater than the market capacity. There is fierce competition in every detail market. From economical cars to high-end commercial vehicles, all brands In the struggle for quality and price, lower prices for the same quality are the goals that OEMs are constantly pursuing. During operation, the air resistance formed by the shape and structure of the car has an important impact on the running speed and acceleration of the car. . [0003] With the stringent requirements of automobile regulations on fuel consumption and emissions and the pursuit of battery life in the ele...
