[0036] During driving, air resistance is an important influencing factor. For example, in high-speed driving, air resistance accounts for more than 70% of the driving resistance of the whole vehicle. Adding wheel spoilers to the vehicle can significantly reduce the air resistance of the whole vehicle. After reducing the air resistance of the whole vehicle, the endurance of the vehicle can be improved, and the vehicle control performance and driving stability can be improved. Therefore, more and more vehicles begin to install spoilers.

[0037] Adding front and rear wheel spoilers to the vehicle can significantly reduce the air resistance of the whole vehicle. However, the existing wheel spoilers are mostly fixedly installed on the bottom of the vehicle. Because the spoiler has a certain height, it is easy to contact the road surface and cause friction and abnormal noise when passing through rough road surfaces, which affects the chassis passability. Moreover, the existing wheel spoilers are generally used to reduce the impact of forward airflow, and are less optimized for the impact of actual yaw angles and crosswinds. In addition, although a one-sided active spoiler is disclosed in the prior art, it still has the problems of complex structure and poor adjustment response.

[0038] In order to solve the problems of complex spoiler structure and poor adjustment response, the present application discloses a vehicle spoiler assembly. By providing a rotation adjustment component and a movable adjustment component, the wheel spoiler can be adjusted both movablely and rotationally to meet different needs. The rotation and movable adjustment of the spoiler are achieved through a simple structure, which reduces air resistance and optimizes the vehicle's maneuverability, making the spoiler structure simpler and the control response more sensitive.

[0039] Before describing in detail the spoiler assembly of the vehicle disclosed in this embodiment, the relevant direction references in this embodiment are explained first: See Figure 1 In this embodiment, the vehicle coordinate system is used as a reference, wherein the length direction of the vehicle mentioned in this embodiment is as follows Figure 1 The X-axis direction is shown in the figure. The positive direction of the X-axis is the vehicle's rearward direction. The width direction is shown in the figure. Figure 1 The Y-axis direction is shown in the figure, where the positive direction of the Y-axis is the right direction of the vehicle, and the height direction is as follows: Figure 1 The Z-axis direction is shown in the figure, where the positive direction of the Z-axis is the upward direction of the vehicle. Furthermore, D corresponds to the X-axis direction for aerodynamic drag, S corresponds to the Y-axis direction for aerodynamic lateral force, and L corresponds to the Z-axis direction for aerodynamic lift. ∞ is the velocity of the incoming airflow, and ψ is the angle between the incoming airflow and the X-axis, which is the yaw angle and the direction of the crosswind. When ψ is 0°, the vehicle is largely unaffected by crosswinds, and the use of side sill spoilers is generally unnecessary.

[0040] Example 1

[0041] The vehicle spoiler assembly disclosed in this embodiment includes wheel spoiler assemblies 100, which are arranged in pairs in front of the left and right wheels of the vehicle in the longitudinal direction of the vehicle. Each wheel spoiler assembly 100 includes a wheel spoiler 110, a mounting base 120, a rotation adjustment component, and a movable adjustment component. The mounting base 120 is fixedly mounted on the vehicle chassis, and the wheel spoiler 110 is movably mounted on the mounting base 120 via the rotation adjustment component and the movable adjustment component.

[0042] It should be understood by those skilled in the art that the wheel spoiler group 100 should be preferably installed in pairs on the front side of the left and right wheels, for example, when a pair is provided, it can be provided on the front side of the left and right front wheels or the front side of the left and right rear wheels, when two pairs are provided, the wheel spoiler group 100 can be provided on the front side of the left and right front wheels and the front side of the left and right rear wheels, and the two pairs have better wind resistance reduction effect. Further, the mounting seat 120 can be fixedly installed on the chassis by welding, bolting, riveting and other different connection methods. As for the shape of the wheel spoiler 110, the wheel spoiler 110 can be provided in a flat plate structure or a curved surface plate structure with an arc, and those skilled in the art can design and select according to actual needs, which is not limited in the embodiment. Next, the rotating adjusting part and the moving adjusting part will be described in detail.

[0043] The moving adjusting part is used to control and drive the wheel spoiler 110 to move and adjust. The moving adjusting part includes a driving unit 130, a guide unit 140 and a moving seat 150. The guide unit 140 is arranged on the lower side surface of the mounting seat 120 and extends along the width direction of the vehicle. The moving seat 150 is movably arranged on the guide unit 140. It should be noted that the guide unit 140 is installed on the lower side surface, which means that when it is installed on the vehicle, it is on the lower side surface. The driving unit 130 is arranged on one side of the moving seat 150 and drives the moving seat 150 to move back and forth along the guide unit 140. The rotating adjusting part is used to control and drive the wheel spoiler 110 to rotate and adjust. The rotating adjusting part includes a first pivot shaft 160 and a first driving member arranged on the moving seat 150. The first pivot shaft 160 is arranged at the lower end of the moving seat 150 and extends along the width direction of the wheel. The wheel spoiler 110 extends along the width direction of the wheel and is fixedly connected to the top of the first pivot shaft 160. The first driving member drives the wheel spoiler 110 to rotate around the first pivot shaft 160. That is, the rotating adjusting part in the embodiment is arranged on the moving seat 150 of the moving adjusting part.

[0044] In one implementation, the driving unit 130 is arranged as a linear driving element, such as a linear motor, a driving cylinder, etc. The guide element can be arranged as any one of a guide groove, a guide rail, etc. For example, taking the driving cylinder, the guide groove and the moving seat 150 as an example, the moving seat 150 is arranged on the output end of the driving cylinder. When the output end of the driving cylinder moves back and forth, it can drive the moving seat 150 and the wheel spoiler 110 to move back and forth to adjust the position.

[0045] In another embodiment, the driving unit 130 is configured as a driving motor and a screw mechanism, a driving motor and a worm gear mechanism, a driving motor and a gear rack mechanism, etc., for example, when configured as a driving motor and a screw mechanism, the guide element is a screw rod, the screw rod is connected to the output end of the driving motor 131, and the moving seat 150 is fixedly arranged on the screw rod slider, when the driving motor 131 drives the screw rod to rotate forward or reversely, the screw rod rotates and drives the screw rod slider and the moving seat 150 to reciprocatingly move for adjustment, and when the worm gear mechanism and the gear rack mechanism are configured, the principle is the same, that is, the rotation of the driving motor 131 is converted into the reciprocating movement of the moving seat 150 for adjustment, and the configuration has the advantages of simple and compact structure, rapid response, and the like.

[0046] Further, in the embodiment, since the first pivot shaft 160 is arranged at the lower end of the moving seat 150 in the width direction of the wheel, the wheel spoiler 110 is rotated and adjusted toward the side of the wheel in front of the wheel, and the first driving member can be a common micro motor or a servo motor, etc.

[0047] It should be noted that, in the embodiment, the rotating and adjusting component at least includes one pivot shaft, when one pivot shaft is arranged, one direction of rotating freedom is provided, for example, when one pivot shaft is arranged, it is preferably arranged in the width direction of the vehicle, and this arrangement can rotate and adjust toward the side of the wheel when adjusting the wheel spoiler 110, when two pivot shafts are arranged, two directions of rotating freedom are provided, and the adjusting range is wider, for example, one of the pivot shafts is arranged in the width direction of the vehicle, and the other pivot shaft is arranged in the height direction of the vehicle, which can rotate toward the side of the wheel and also can be flipped to adjust, for example, when affected by the lateral wind, the pivot shaft arranged in the height direction can be used for adjustment.

[0048] With the design of the structure, the wheel spoiler 110 is adjusted by the rotating and adjusting component and the moving adjusting component, the angle and position of the wheel spoiler 110 can be adjusted according to the requirements (such as wind power, wind direction change), the air resistance can be reasonably reduced, and the vehicle can be more stable when driving at high speed.

[0049] Further, after the driving air resistance is reduced, the vehicle can be more energy-saving when driving, the fuel consumption or power consumption is saved, the endurance is improved, and the angle and position of the wheel spoiler 110 can be adjusted according to different requirements such as vehicle speed, driving direction, wind direction, etc., the movement is controlled by the driving unit 130, the guide unit 140 and the moving seat 150, the rotation is controlled by the first pivot shaft 160, the structure is more simple, the production cost is reduced, and the advantages of rapid response and higher freedom are also provided.

[0050] For example, when the vehicle speed is low, the wheel spoiler 110 can be in the retracted state, when the vehicle speed is high, the wheel spoiler 110 rotates relative to the side of the wheel tire, and the height of the spoiler and the area of the tire covered by the spoiler are changed, so as to adjust the spoiler area to reduce wind resistance. When the road condition is poor, the wheel spoiler 110 returns to the retracted state, thereby improving the chassis passability, avoiding the abnormal noise caused by the wheel spoiler 110 scraping the ground, and preventing the wheel spoiler device from being damaged.

[0051] Next, referring to Figure 2 The spoiler assembly of the vehicle disclosed in the embodiment is described in detail, wherein the mounting seat 120 is in a plate-shaped structure extending along the width direction of the vehicle, the upper side surface is fixed to the chassis, and the lower side surface is provided with a guide unit 140, the guide unit 140 includes a guide portion extending along the width direction of the vehicle, and one side of the mounting seat 120 is also fixedly provided with a rack 142 extending along the width direction. Specifically, the guide portion can be a common guide groove, guide rail, sliding rail or the like structure, the guide portion can assist the moving seat 150 to reciprocate along the width direction of the vehicle, and drive the wheel spoiler 110 to move along the width direction of the vehicle.

[0052] The upper side of the moving seat 150 is provided with a guided portion matched with the guide portion, the moving seat 150 is matched and engaged with the guide portion through the guided portion, the side of the moving seat 150 close to the rack 142 is provided with a protruding portion 151 protruding from the mounting seat 120, and the driving unit 130 is arranged on the protruding portion 151, and the driving unit 130 includes a driving motor 131 and a driving gear 132 arranged on the output end of the driving motor 131, the driving gear 132 is matched and engaged with the rack 142, and the driving motor 131 drives the driving gear 132 to rotate and drive the moving seat 150 to reciprocate along the guide portion.

[0053] It should be noted that the moving seat 150 is matched and engaged with the guide portion through the guided portion, which means that the guide portion and the guided portion are movably or movably matched or communicated, for example, when the guide portion is arranged as a guide groove, the guided portion is arranged as a guide wheel matched with the guide groove, when the guide portion is arranged as a sliding rail, the guided portion is arranged as a sliding block matched with the sliding rail, and the person skilled in the art can design and select according to the actual needs, and the embodiment does not make specific limitation.

[0054] The embodiment also discloses a spoiler assembly of a vehicle, the guide portion is a guide rail 141 extending along the width direction of the vehicle, and the guided portion is a boss 152 matched with the guide rail 141. The protruding portion 151 is arranged at one end of the moving seat 150 along the length direction of the vehicle, and the driving motor 131 and the driving gear 132 are arranged on the protruding portion 151 along the height direction of the vehicle.

[0055] With the above structure, the guide rail 141 and the boss 152 cooperate to guide and direct, and see Figure 2 The guide rail 141 in the embodiment is designed as a long strip-shaped component, which is designed to provide a smooth and accurate moving path. When the guide rail 141 cooperates with the boss 152, they together form an accurate and stable moving system to ensure the moving accuracy of the moving seat 150.

[0056] It should be noted that the protruding part 151 on one side of the moving seat 150 is fixedly provided with a driving motor 131, and the output end of the driving motor 131 is a driving gear 132. When the driving motor 131 drives the driving gear 132 to mesh along the length direction of the rack 142 and reciprocate, the gear drives the driving motor 131 and the moving seat 150 to move, and the moving seat 150 further drives the wheel spoiler 110 to reciprocate.

[0057] The embodiment also discloses a spoiler assembly of a vehicle. In the width direction of the vehicle, the width dimension of the wheel spoiler 110 is equal to or greater than the width dimension of the wheel, the extension dimension of the mounting seat 120 is greater than the length dimension of the wheel spoiler 110, and the rotation angle of the wheel spoiler 110 towards the front wheel side is in the range of 0-90°.

[0058] For example, the width dimension of the wheel spoiler 110 is equal to or slightly greater than the width dimension of the tire of the wheel, for example, slightly greater by 10mm, 15mm, 20mm, etc. The design purpose is to provide better spoiler effect and reduce wind resistance. The extension dimension of the mounting seat 120 is greater than the length dimension of the wheel spoiler 110, for example, greater than 30mm, 40mm, 45mm, etc. The purpose is to provide more adjustment size and adjustment distance. The rotation angle of the wheel spoiler 110 towards the front wheel side is in the range of 0-90°, which can be adjusted according to actual needs. For example, when the rotation angle is 0°, the wheel spoiler 110 is attached to one side of the vehicle chassis. When the rotation angle is 90°, the rotation angle is maximum, and the wind shielding area is also larger. For example, when the rotation angle is 30°, 45°, 60°, etc., the smaller the rotation angle, the smaller the spoiler wind shielding area, and the larger the rotation angle, the larger the spoiler wind shielding area. In the actual driving process, the adjustment angle can be adjusted according to the driving speed and the road surface condition. For example, the greater the driving speed, the greater the adjustment angle, and the wheel spoiler 110 can be rotated and retracted when passing through a bumpy road. Those skilled in the art can adjust it according to actual needs, and the embodiment does not make specific limitations.

[0059] The embodiment also discloses a spoiler assembly of a vehicle. In the width direction of the vehicle, the width dimension of the wheel spoiler 110 is equal to or greater than the width dimension of the wheel, the extension dimension of the mounting seat 120 is greater than the length dimension of the wheel spoiler 110, and the rotation angle of the wheel spoiler 110 towards the front wheel side is in the range of 0-90°. Figure 2, the rotating adjusting part further comprises a second pivot shaft 170 arranged on the moving seat 150, the second pivot shaft 170 is rotatably arranged between the moving seat 150 and the first pivot shaft 160, the moving seat 150 is internally provided with a second driving member connected with the second pivot shaft 170, the rotating axis of the first pivot shaft 160 is perpendicular to the rotating axis of the second pivot shaft 170, the rotating axis of the first pivot shaft 160 is the same as the width direction of the vehicle, and the rotating axis of the second pivot shaft 170 is the same as the height direction of the vehicle. The second driving member drives the first pivot shaft 160 and the wheel spoiler 110 to rotate around the second pivot shaft 170.

[0060] It should be noted that when the second pivot shaft 170 is rotatably arranged between the moving seat 150 and the first pivot shaft 160, the first pivot shaft 160 is rotatably arranged on the second pivot shaft 170, at this time, the rotating adjusting part is an adjusting part with two rotating degrees of freedom, specifically, the second pivot shaft 170 can drive the first pivot shaft 160 and the wheel spoiler 110 to rotate along the height direction of the vehicle, and the first pivot shaft 160 can drive the wheel spoiler 110 to rotate along the width direction of the vehicle, when the lateral wind is received, the wind resistance can be reduced when rotating along the width direction of the vehicle.

[0061] By adopting the above structure, the rotating adjusting part further comprises the second pivot shaft 170, the rotating axis of the first pivot shaft 160 is perpendicular to the rotating axis of the second pivot shaft 170, which is equivalent to that the wheel spoiler 110 further increases one rotating degree of freedom, so that the rotating adjustment can be further made when the side wind or other conditions are encountered, the wind resistance is reduced, the down pressure is optimized, the adaptability is increased, and the handling of the whole vehicle is improved. For example, referring to Figure 1 When the wind direction changes into the side wind, for example, the included angle ψ between the air inflow direction of the side wind and the X axis is 10°, the rotating adjusting part can be rotated by 10° to improve the wind blocking and disturbing effect. By adjusting the angle of the spoiler, the steering characteristics of the vehicle can be improved, the handling of the vehicle is optimized, and the driver is more easily to control the vehicle.

[0062] The embodiment further discloses a spoiler assembly of a vehicle.

[0065] For example, referring to Figure 4And Figure 5 Each of the threshold spoiler assembly 200 includes a threshold mounting seat 210, a telescopic adjusting part, a rotating part and a threshold spoiler 250, the upper side surface of the threshold mounting seat 210 is fixed to the chassis under the threshold and extends along the length direction of the vehicle, the telescopic adjusting part is telescopically arranged on the lower side surface of the threshold mounting seat 210, the rotating part is rotatably arranged at one end of the telescopic adjusting part away from the threshold mounting seat 210, and the threshold spoiler 250 is arranged on the rotating part. With the design of this structure, the threshold spoiler assembly 200 can further reduce the resistance and impact of the side wind, significantly improve the side wind stability, and also has the advantages of simple structure, rapid control response and low cost.
