Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an air deflector structure for the front wheels of an automobile.

[0002] And vehicles Background Art

[0003] With the gradual intensification of the energy crisis and the continuous rise of oil prices, the energy consumption of automobiles has become an important factor that people care about when purchasing automobiles, and wind resistance is a key indicator affecting driving energy consumption. On the other hand, with the electrification of automobiles, the proportion of wind resistance in the overall vehicle energy consumption is gradually increasing, and the impact on energy consumption is greater. Especially at a vehicle speed of 120 km / h, about 65% of the power is used to overcome wind resistance. Therefore, in order to pursue an extreme performance experience, low wind resistance has become a trend in the development of automobiles.

[0004] During the driving process of a vehicle, due to the influence of air resistance, the energy consumption of the vehicle will increase and the cruising range will decrease. Therefore, in order to reduce the air resistance of the vehicle during driving, the related technology is to add an air deflector in front of the wheels of the vehicle, and use the air deflector to reduce the air resistance of the vehicle during driving, so as to achieve the purpose of reducing wind resistance. The air deflector structures of some existing vehicle models are not reasonably designed and are usually single plates arranged vertically, so the structure is not firm enough. Therefore, it is necessary to invent a new air deflector structure for the front wheels of an automobile. Content of the Utility Model

[0024] As shown Figures 1 to 5 in the structure of a front-wheel wind deflector for an automobile, which includes a wind deflector body 1. The wind deflector body 1 is of an L-shaped structure. The wind deflector body 1 includes a fixing plate 11 and a wind deflector 12. The wind deflector 12 is perpendicular to the fixing plate 11 and extends towards the ground. A number of groups of reinforcing ribs 13 are connected between the fixing plate 11 and the wind deflector 12. In this embodiment, five groups of reinforcing ribs 13 are provided. The fixing plate 11 is fixedly connected to the bottom of the front wheel fender 2 and is located in front of the front wheel of the vehicle. During the driving of the vehicle, the air flow in front of the wheel will directly flow towards the front of the wheel and generate air resistance to the wheel. The setting of the wind deflector 12 can reduce the impact of the front air flow on the wheel.

[0025] In order to facilitate the assembly of the wind deflector body 1 and make reasonable use of the space at the bottom of the vehicle body, the wind deflector body 1 is arranged in the space between the inner side wall of the front bumper lower body 3 and the outer side wall of the engine under shield 4.

[0026] The front-wheel wind deflector provided by this specific embodiment includes two parts: the left and right front-wheel wind deflectors; the wind deflector structure at the right front wheel is mirror-symmetrical to the wind deflector structure at the left front wheel. In addition to solving the strength problem of the existing wind deflector structure, the present invention can also solve some problems of the existing wind deflector structure design that is not reasonable enough and the diversion effect is not good through the optimization of the structure.

[0027] One end of the wind deflector 12 extends towards the inside of the vehicle and exceeds the inner edge of the wheel, and the part exceeding the wheel forms a wind deflector structure for the vehicle suspension; the other end of the wind deflector 12 extends towards the outside of the vehicle and exceeds the center axis of the wheel (due to the matching problem of the vehicle body data, the part exceeding the center axis of the wheel is not shown in the drawings), and this part forms a wind deflector structure for the tire.

[0028] In order to increase the structural stiffness, the reinforcing rib 13 is of a triangular structure, one side of which is fixedly connected to the lower end surface of the fixing plate 11, and the other side is fixedly connected to the side of the wind deflector 12 facing the wheel.

[0029] In order to achieve a good diversion effect on both sides of the wind deflector 12, the length of the wind deflector 12 is 180 - 250 mm.

[0030] In order to achieve a good diversion and wind deflector effect, the height of the wind deflector 12 is 40 - 70 mm. For vehicles with a lower chassis such as sedans, the height of the wind deflector 12 can be set lower, and for vehicles with a higher chassis such as off-road vehicles, the height of the wind deflector 12 can be set higher.

[0031] Meanwhile, considering that the wheels will disturb the air flow in the entire wheel cavity during high-speed rotation, a large amount of turbulent flow will be formed around the wheels, resulting in an increase in air resistance and ultimately affecting the aerodynamic drag coefficient of the whole vehicle. The wind blocking plate 12 is of a large-angle arc-shaped structure, and the wind blocking plate 12 bends backward from the middle to both sides. This diversion structure can reduce the flow rate and turbulent flow of the air flow entering the wheel cavity of the wheel 6, allowing the air flow to flow towards the rear of the vehicle more quickly.

[0032] To facilitate the assembly of the fixing plate 11 and the front wheel fender 2, the fixing plate 11 is fixedly connected to the front wheel fender 2 by riveting. The rivets 14 are used to cooperate with the rivet holes arranged at intervals along the length direction of the fixing plate 11. This assembly method has a low cost and is convenient for installation.

[0033] The material of the wind blocking plate body 1 is TPV thermoplastic vulcanized rubber, which has good flexibility and wear resistance.

[0034] Both left and right ends of the wind blocking plate 12 are provided with arc chamfers, so that the connection opening forms a guiding structure with a decreasing opening spacing from top to bottom.

[0035] In addition, the present utility model further includes a vehicle, and the vehicle is provided with the above-mentioned automotive front wheel wind blocking plate structure.

[0036] Through a large number of analysis and verification and from the results of aerodynamic simulation analysis, installing a suitable wind blocking plate structure will improve the air flow at the bottom of the vehicle and the tires, reduce the flow rate and turbulent flow of the air flow at the bottom of the vehicle, allow the air flow to flow towards the rear of the vehicle more quickly, have a "diversion" effect, and can also be regarded as a "spoiler" for the chassis and tires, effectively reducing the aerodynamic drag and energy consumption of the whole vehicle. On the other hand, as the working conditions of people using cars become more diverse and complex, the pain points caused by the appearance design defects of cars to users have also become one of the reasons for customer complaints. When the vehicle passes through road surface water or bad road conditions, the splashing of mud and water at the bottom of the vehicle has an impact on the appearance of the vehicle, reducing the user experience value. Using the present utility model can also solve this problem and improve the user experience and satisfaction.

[0037] In the description of the present utility model, it should be understood that terms such as "upper", "lower", "front", "rear", "left", "right", "bottom", "inner", "outer", "one end", "one side", "both ends", "both sides", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0038] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various improvements are made by adopting the method concept and technical solution of the present utility model, or directly applied to other occasions, they all fall within the protection scope of the present utility model.
