[0043] The following description will be made with reference to the accompanying drawings. Figures 1-4 The spoiler assembly 10 according to the embodiments of the present application is described.

[0044] As shown in Figure 1 and Figure 2 , the spoiler assembly 10 according to the embodiments of the present application comprises a movable spoiler 1 and a driving device 2.

[0045] Specifically, as shown in Figure 1 , the spoiler assembly 10 is used for a vehicle 100, and the spoiler assembly 10 can provide additional downforce for the vehicle 100 by changing the flow direction of the air flow, so that the contact between the vehicle 100 and the ground is more closely, thereby enhancing the grip of the vehicle 100 and improving the stability of driving. The spoiler assembly 10 can guide the air flow to flow more smoothly through the vehicle body 30, thereby reducing air resistance. By reducing air resistance and improving stability, the power source of the vehicle 100 does not need to consume excessive energy to maintain high-speed driving, thereby achieving the effect of energy saving and emission reduction.

[0046] As shown in Figure 1 and Figure 2As shown, the active spoiler 1 is rotatably arranged on the upper side of the rear window glass 20 of the vehicle 100, and the driving device 2 is adapted to be arranged on the vehicle 100 and connected with the active spoiler 1 for driving the rear end of the active spoiler 1 to swing up and down. The driving device 2 drives the rear end of the active spoiler 1 to swing up and down, and the active spoiler 1 can be switched between the raised state and the lowered state. When the active spoiler 1 is in the raised state, the active spoiler 1 guides the air above the top of the vehicle 100 to the upper surface of the active spoiler 1, thereby avoiding the air being divided into two air flows from the upper surface and the lower surface of the spoiler assembly 10, accelerating the air flow speed on the roof, reducing the air energy dissipation on the back of the vehicle 100, reducing the overall vehicle drag, and improving the fuel economy of the vehicle 100. When the active spoiler 1 is in the lowered state, the tail end of the active spoiler 1 is attached to the same plane as the rear window glass 20 of the vehicle 100, at this time, the air flow can be directly guided to pass over the upper surface of the rear window glass 20, a large amount of air flow can directly flush the rear window glass 20 of the vehicle 100, increase the air flow speed above the rear window glass 20, and can play a role in cleaning the rear window glass 20 by the air flow, and improve the visibility of the field of view of the rear window glass 20.

[0047] According to the spoiler assembly 10 of the embodiment of the present application, by rotatably arranging the active spoiler 1 on the upper side of the rear window glass 20 of the vehicle 100, and driving the driving device 2 to drive the rear end of the active spoiler 1 to swing up and down, the active spoiler 1 can be switched between the raised state and the lowered state. When the active spoiler 1 is in the raised state, the air energy dissipation on the back of the vehicle 100 can be reduced, the overall vehicle drag can be reduced, and the fuel economy of the vehicle 100 can be improved. When the active spoiler 1 is in the lowered state, the tail end of the active spoiler 1 is attached to the same plane as the rear window glass 20 of the vehicle 100, the air flow can be directly guided to pass over the upper surface of the rear window glass 20, a large amount of air flow can directly flush the rear window glass 20 of the vehicle 100, increase the air flow speed above the rear window glass 20, and can play a role in cleaning the rear window glass 20 by the air flow, and improve the visibility of the field of view of the rear window glass 20.

[0048] In some embodiments of the present application, as shown in Figure 2 and Figure 3 The spoiler assembly 10 further comprises a fixed rod 3 extending along the left-right direction of the vehicle 100 (such as the left-right direction shown in Figure 1 The front end of the active spoiler 1 is rotatably connected with the fixed rod 3. It can be understood that the front end of the active spoiler 1 is mounted above the rear window glass 20 of the vehicle 100 through the fixed rod 3, the driving device 2 drives the rear end of the active spoiler 1 to swing up and down, and the active spoiler 1 can be switched between the raised state and the lowered state, which is convenient for the installation and rotation of the active spoiler 1.

[0049] Further, as shown in Figure 2 and Figure 3 , the driving device 2 comprises a driving motor 21, a gear 22 and a movable rack 23, the driving motor 21 is suitable to be arranged on the vehicle 100, the gear 22 is suitable to be arranged on the vehicle 100 and connected with the output shaft 211 of the driving motor 21, the movable rack 23 is movably arranged on the vehicle 100 and engaged with the gear 22, and the movable rack 23 is suitable to be connected with the end of the movable spoiler 1 away from the fixed rod 3. When the driving motor 21 works, the output shaft 211 of the driving motor 21 rotates to drive the gear 22 to rotate, and the gear 22 drives the movable rack 23 to move when rotating, and the movable rack 23 connected with the movable spoiler 1 can drive the rear end of the movable spoiler 1 to swing up and down, so as to realize the automatic switching of the movable spoiler 1 between the raised state and the lowered state, and the switching mode is relatively simple.

[0050] Further, the projection of the movable rack 23 on the plane perpendicular to the left-right direction is an arc with the axis of the fixed rod 3 as the center, and the inner arc surface of the movable rack 23 is engaged with the gear 22. After the engagement of the movable rack 23 and the gear 22, the arc-shaped movable rack 23 with the axis of the fixed rod 3 as the center can drive the rear end of the movable spoiler 1 to swing up and down, so as to realize the rotation of the movable spoiler 1 with the axis of the fixed rod 3 as the center, and the rotation of the movable spoiler 1 is relatively reliable.

[0051] In some embodiments of the present application, as shown in Figure 2 and Figure 3 , the driving motor 21 comprises two output shafts 211 extending to the left and right sides of the vehicle 100, the gear 22 and the movable rack 23 are two corresponding to the two output shafts 211, the two gears 22 and the two movable racks 23 are respectively arranged on the two sides of the driving motor 21 along the left-right direction of the vehicle 100, and the movable spoiler 1 is two, the two movable racks 23 respectively drive the rear ends of the two movable spoilers 1 to swing up and down, so as to split the movement of the movable spoiler 1 into two parts for driving, so as to make the driving force of the movement of the movable spoiler 1 sufficient, and increase the driving reliability of the driving device 2.

[0052] In some embodiments of the present application, as shown in Figure 3 and Figure 4 , the spoiler assembly 10 further comprises a movable connecting rod 4, one end of the length direction of the movable connecting rod 4 is fixedly connected with the movable rack 23, and the other end of the movable connecting rod 4 is connected with the end of the movable spoiler 1 away from the fixed rod 3. The movable connecting rod 4 can play a certain force transmission role, and transmit the movement of the movable rack 23 to the movable spoiler 1, so as to make the force transmission process between the movable rack 23 and the movable spoiler 1 relatively simple and reliable.

[0053] Furthermore, the movable link 4 includes a first link and a second link. The first link extends in the left-right direction and one end is connected to the movable rack 23. The second link extends in the up-down direction (e.g., ...). Figure 1 The rack extends in the vertical direction (as shown) and one end is rotatably connected to the end of the first connecting rod away from the movable rack 23, while the other end is rotatably connected to the end of the movable spoiler 1 away from the fixed rod 3. The direction of force transmission can be changed in the left-right and up-down directions, which facilitates the transmission of force between the movable rack 23 and the movable spoiler 1, making the force transmission process between the movable rack 23 and the movable spoiler 1 simpler and more reliable.

[0054] In some embodiments of the present invention, such as Figure 3 As shown, the vehicle 100 has a receiving space 24 located above the rear window glass 20. The upper end of the receiving space 24 is open, and the drive unit 2 is disposed within the receiving space 24. The spoiler assembly 10 also includes a cover plate 5, which covers the open end of the receiving space 24. This cover plate 5 can relatively tightly house the drive unit 2 within the body 30 of the vehicle 100, protecting the drive unit 2 from external impacts and preventing damage. Simultaneously, the cover plate 5 can prevent dust and other particles from entering the drive unit 2, thus avoiding damage, and also contributes to the aesthetic appearance of the vehicle body 30. The cover plate 5 has clearance holes through which at least a portion of the drive unit 2 passes. This allows the movement of the movable rack 23 within the receiving space 24 to be transmitted to the movable spoiler 1 via the portion of the drive unit 2 passing through the clearance holes, increasing the reliability of force transmission between the movable rack 23 and the movable spoiler 1.

[0055] In some embodiments of the present invention, such as Figure 1 As shown, the spoiler assembly 10 also includes a spoiler body 6, which is located on the upper side of the rear window glass 20.

At this time, the spoiler body 6 and the vehicle body 30 form a hollow spoiler, so that the spoiler body 6 can reduce its own weight and reduce the contact area with the air while maintaining sufficient rigidity, thereby reducing air resistance. The roof air flow is forcibly divided into two air flows with different flow directions and sizes, part of the air flow passes through the upper surface of the rear window glass 20, and part of the air flow passes through the upper surface of the spoiler body 6, thereby meeting various use requirements.

The intermediate structure, the two spoiler arms 62 and the vehicle body 30 jointly form a hollow spoiler, so that the spoiler body 6 can reduce its own weight and reduce the contact area with the air while maintaining sufficient rigidity, thereby reducing air resistance. The roof air flow is forcibly divided into two air flows with different flow directions and sizes, part of the air flow passes through the upper surface of the rear window glass 20, and part of the air flow passes through the upper surface of the spoiler body 6, thereby meeting various use requirements.

[0057] Further, as shown in Figure 1 The spoiler body 6 further includes a limiting portion 63, one end of the length direction of the limiting portion 63 is connected with the intermediate structure 61, and the other end extends forward to be connected with the vehicle body 30 of the vehicle 100, and the limiting portion 63 is configured to abut against at least part of the lower surface of the limiting portion 63 with the upper end surface of the movable spoiler 1 when the rear end of the movable spoiler 1 swings upward. The limiting portion 63 can limit the movable spoiler 1, avoid excessive upward rotation of the movable spoiler 1, and increase the reliability of the position of the movable spoiler 1.

[0066] In some embodiments of the present application, as shown in Figure 1 and Figure 5 It is judged whether the visual field demand and the priority of the aerodynamic drag reduction of the vehicle 100 further include: judging whether the front wiper of the vehicle 100 is stopped working for more than 15s; if no, the visual field demand is prior, the rear window glass 20 can store water, the visual field of the user is blocked, the movable spoiler 1 is controlled to swing downward, the movable spoiler 1 is in the lowered state, the tail end of the movable spoiler 1 is attached to the rear window glass 20 of the vehicle 100 to be in the same plane, at this time, the airflow can be directly guided to pass over the upper surface of the rear window glass 20, a large amount of airflow can directly flush the rear window glass 20 of the vehicle 100, the air flow rate on the rear window glass 20 is increased, the effect of cleaning the rear window glass 20 by the airflow is achieved, and the visibility of the visual field of the rear window glass 20 is improved;

[0067] If yes, it is judged whether the speed of the vehicle 100 exceeds a threshold value, which can be determined according to the shape and other parameters of the vehicle 100; if yes, the aerodynamic drag reduction is preferred, at this time the air group of the vehicle 100 produces a larger noise, the movable spoiler 1 is controlled to swing upward, the movable spoiler 1 is in the raised state, the movable spoiler 1 guides the air above the top of the vehicle 100 to the upper surface of the movable spoiler 1, thereby avoiding the air to be divided into two air flows from the upper surface and the lower surface of the spoiler assembly 10, accelerating the air flow speed above the roof, thereby reducing the air energy dissipation at the back of the vehicle 100, reducing the overall vehicle wind resistance, and improving the fuel economy of the vehicle 100; if no, the field of view requirement is preferred, the movable spoiler 1 is controlled to swing downward, the movable spoiler 1 is in the lowered state, the tail end of the movable spoiler 1 is attached to the rear window glass 20 of the vehicle 100 to be in the same plane, at this time the air flow can be directly guided to pass over the upper surface of the rear window glass 20, a large amount of air flow can directly flush the rear window glass 20 of the vehicle 100, increase the air flow speed above the rear window glass 20, and have the effect of cleaning the rear window glass 20 of the vehicle 100 by the air flow, and improve the visibility of the field of view of the rear window glass 20.

[0068] The vehicle 100 according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0069] Specifically, as shown in the figure, Figures 1-5 The adjustment of the position of the movable spoiler 1 can be divided into two modes of manual and automatic. In the manual mode, the original position of the movable spoiler 1 is directly in the aerodynamic drag reduction state, that is, the raised mode, and the user can operate the movable spoiler 1 to be raised or lowered through the in-vehicle button if needed. In the automatic mode, the rain sensor and the vehicle speed sensor can feed back signals to the ECU (Electronic Control Unit) according to the current driving state of the vehicle 100 and the working state of the front wiper, and drive the motor 21 to control the position of the movable spoiler 1 to be raised or lowered in real time.

[0070] When the movable spoiler 1 is in the raised state, the movable spoiler 1 guides the air above the roof to the upper surface of the spoiler, thereby avoiding the air to be divided into two air flows from the upper surface and the lower surface of the hollow spoiler assembly 10, accelerating the air speed above the roof, thereby reducing the air energy dissipation at the back of the vehicle 100, reducing the overall vehicle wind resistance, and improving the fuel economy of the vehicle 100; when the movable spoiler 1 is in the lowered state, the tail end of the movable spoiler 1 is attached to the rear window glass 20 of the vehicle 100 to be in the same plane, at this time the air flow can be directly guided to pass over the upper surface of the rear window glass 20, a large amount of air can directly flush the rear window glass 20 of the vehicle 100, increase the air flow speed above the rear window glass 20, and have the effect of cleaning the rear window glass 20 of the vehicle 100 by the air flow, and improve the visibility of the field of view of the rear window glass 20.

[0071] When the vehicle 100 is in driving process, not only can be through manual control, let the active spoiler 1 is always in the state of rise or lower, that is, always keep the aerodynamic drag reduction mode or the cleaning mode of the rear window glass 20. Also can be through the automatic mode work logic automatically adjust the state of the active spoiler 1, in the driving condition, the vehicle speed reaches the threshold value, the airflow above the roof is accelerated, at this time if the rainfall sensor receives the rainfall level signal to the ECU, the front wiper is driven to work automatically, and the current wiper works continuously for more than 10s, it can be determined that the field of view priority is given priority to, at this time the field of view priority of the rear window glass 20 is higher than the aerodynamic drag reduction function. The ECU will send control signal to control motor drive gear 22 rotation, drive the active rack 23. The active link 4 is connected to the active rack 23 at one end, and the other end is connected to the rear end of the active spoiler 1. When the active gear 22 moves downward, the active spoiler 1 can be controlled to lower state, the tail end of the active spoiler 1 is attached to the rear window glass 20, and the airflow is guided to wash the rainwater on the upper surface of the rear window glass 20. When the wiper stops moving for more than 15s, the priority of the field of view priority is lower than the aerodynamic drag reduction function, and the ECU will send control signal to control motor drive, drive the active rack 23 upward, and the active spoiler 1 can be controlled to rise state, change to aerodynamic drag reduction mode.

[0072] The active spoiler 1 device rises and lowers as follows: after each start or ignition of the vehicle 100, the driving motor 21 drives the active spoiler 1 to the fully lowered or fully raised state to check the state information of the device; during the driving process of the vehicle 100, when the driving motor 21 receives the ECU signal, the driving gear 22 rotates in the specified direction, the active rack 23 connected with the active spoiler 1 is engaged, thereby driving the active rack 23 to move downward along the specified direction until it stops at the specified limit state. Because there is a movable part matching relationship between the active spoiler 1 and the active link 48, the fixed rod 3 can fix the active spoiler 1, so as to realize the active spoiler 1 in the state of rise or lower, that is, the realization of the drag reduction function and the cleaning function on the upper surface of the rear window glass 20.
