[0043] Reference below Figure 1-Figure 4 A spoiler assembly 10 according to an embodiment of the present invention is described.

[0044] like Figure 1 and Figure 2 As shown, a spoiler assembly 10 according to an embodiment of the present invention includes a movable spoiler 1 and a driving device 2 .

[0045] Specifically, Figure 1 As shown, the spoiler assembly 10 is used for a vehicle 100. The spoiler assembly 10 can provide additional downforce for the vehicle 100 by changing the flow direction of the airflow, so that the contact between the vehicle 100 and the ground is closer, thereby enhancing the grip of the vehicle 100 and improving the driving stability. The spoiler assembly 10 can guide the airflow 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 too much energy to maintain high-speed driving, thereby achieving the effect of energy saving and emission reduction.

[0046] like Figure 1 and Figure 2As shown, the active spoiler 1 is rotatably disposed on the upper side of the rear window glass 20 of the vehicle 100, and the driving device 2 is suitable for being disposed on the vehicle 100. The driving device 2 is connected to the active spoiler 1 and is used to drive 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 switch between a raised state and a 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 and guides the air to the upper surface of the active spoiler 1, thereby avoiding the air from being divided into two airflows and going through the upper surface and the lower surface of the spoiler assembly 10, accelerating the air flow speed of the roof, thereby reducing the air energy dissipation at the back of the vehicle 100, reducing the wind resistance of the whole vehicle, and improving the fuel economy of the vehicle 100; when the active spoiler 1 is in the lowered state, the rear end of the active 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 through 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, increase the air flow rate on the rear window glass 20, play the effect of airflow cleaning the rear window glass 20, and improve the visibility of the rear window glass 20.

[0047] According to the spoiler assembly 10 of the embodiment of the present invention, 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 drives the rear end of the active spoiler 1 to swing up and down, so that the active spoiler 1 can switch between a raised state and a lowered state. When the active spoiler 1 is in the raised state, the air energy dissipation at the back of the vehicle 100 can be reduced, the wind resistance of the whole vehicle 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 rear end of the active spoiler 1 and the rear window glass 20 of the vehicle 100 are attached to the same plane, and the airflow can be directly guided to pass through 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, increase the air flow rate on the rear window glass 20, play the effect of airflow cleaning the rear window glass 20, and improve the visibility of the field of view of the rear window glass 20.

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

[0049] Furthermore, if Figure 2 and Figure 3 As shown, the driving device 2 includes a driving motor 21, a gear 22 and a movable rack 23. The driving motor 21 is suitable for being arranged on the vehicle 100. The gear 22 is suitable for being arranged on the vehicle 100 and connected to the output shaft 211 of the driving motor 21. The movable rack 23 is movably arranged on the vehicle 100 and meshes with the gear 22. The movable rack 23 is suitable for being connected to an end of the active spoiler 1 away from the fixed rod 3. When the driving motor 21 is working, the output shaft 211 of the driving motor 21 rotates, driving the gear 22 to rotate. When the gear 22 rotates, it drives the movable rack 23 to move. The movable rack 23 is connected to the active spoiler 1, and can drive the rear end of the active spoiler 1 to swing up and down, so that the active spoiler 1 can be automatically switched between the raised state and the lowered state, and the switching method is relatively simple.

[0050] Furthermore, the projection of the movable rack 23 on a 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 meshed with the gear 22. After the movable rack 23 is meshed with 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, and the rotation of the movable spoiler 1 with the axis of the fixed rod 3 as the center can be realized, and the rotation of the movable spoiler 1 is more reliable.

[0051] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the driving motor 21 includes 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 both sides of the driving motor 21 along the left and right directions of the vehicle 100, there are two movable spoilers 1, and the two movable racks 23 respectively drive the rear ends of the two active spoilers 1 to swing up and down, so that the movement of the active spoiler 1 can be split into two places for driving, so that the driving force of the movement of the active spoiler 1 can be more sufficient, and the driving reliability of the driving device 2 can be increased.

[0052] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the spoiler assembly 10 further includes a movable link 4, one end of which in the length direction is fixedly connected to the movable rack 23, and the other end of the movable link 4 is connected to the end of the movable spoiler 1 away from the fixed rod 3. The movable link 4 can play a certain force transmission role, transmitting the movement of the movable rack 23 to the movable spoiler 1, so that the force transmission process between the movable rack 23 and the movable spoiler 1 is 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 (such as Figure 1 The movable rack 23 and the movable spoiler 1 are connected to each other in the vertical direction (in the vertical direction shown in the figure) and one end is rotatably connected to the end of the first connecting rod away from the movable rack 23, and the other end is rotatably connected to the end of the movable spoiler 1 away from the fixed rod 3. The force transmission direction can be changed in the left-right direction and the up-down direction, which is convenient for realizing the force transmission 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 simple and reliable.

[0054] In some embodiments of the present invention, Figure 3 As shown, the vehicle 100 has a storage space 24, which is located on the upper side of the rear window glass 20, and the upper end of the storage space 24 is open. The drive device 2 is arranged in the storage space 24, and the spoiler assembly 10 also includes a cover plate 5, which is arranged at the open mouth of the storage space 24, so that the drive device 2 can be relatively sealed in the body 30 of the vehicle 100, and the drive device 2 can be protected, and the drive device 2 can be prevented from being impacted by external forces, and the drive device 2 can be prevented from being damaged. At the same time, the cover plate 5 can prevent dust and other particles from entering the drive device 2, and avoid damage to the drive device 2, and can make the body 30 of the vehicle 100 more beautiful. The cover plate 5 is provided with an avoidance hole, and at least part of the drive device 2 is penetrated in the avoidance hole, so that the movement of the movable rack 23 in the storage space 24 is transmitted to the active spoiler 1 through the part of the drive device 2 penetrated in the avoidance hole, thereby increasing the reliability of the force transmission between the movable rack 23 and the active spoiler 1.

[0055] In some embodiments of the present invention, Figure 1 As shown, the spoiler assembly 10 also includes a spoiler body 6, which is arranged on the upper side of the rear window glass 20. The length direction of the spoiler body 6 (such as Figure 1The two ends of the spoiler body 6 (in the left and right directions shown) are fixedly connected to the body 30 of the vehicle 100, and the part of the spoiler body 6 is separated from the body 30 and defines an installation space between the spoiler body 6 and the body 30, and the movable spoiler 1 is arranged in the installation space. The spoiler body 6 can increase the guiding effect of the spoiler assembly 10. The spoiler body 6 guides the air above the top of the vehicle 100 and guides the air to the upper surface of the spoiler body 6, thereby avoiding the air from being divided into two air flows and going from the upper surface and the lower surface of the spoiler assembly 10, speeding up the air flow speed on the roof, thereby reducing the air energy dissipation on the back of the vehicle 100, reducing the wind resistance of the whole vehicle, and improving the fuel economy of the vehicle 100. At this time, a hollow spoiler is formed between the spoiler body 6 and the body 30, so that the spoiler body 6 can reduce its own weight while maintaining sufficient rigidity, and reduce the contact area with the air, thereby reducing air resistance. The airflow on the roof is forcibly divided into two airflows with different flow directions and sizes. One part of the airflow passes through the upper surface of the rear window glass 20, and the other part of the airflow passes through the upper surface of the spoiler body 6, meeting various usage requirements.

[0056] Furthermore, if Figure 1 As shown, the spoiler body 6 includes an intermediate structure 61 and two spoiler arms 62, the intermediate structure 61 is separated from the vehicle body 30, one end of the two spoiler arms 62 in the length direction is fixedly connected to the two ends of the intermediate structure 61 in the left and right directions, the other end of the spoiler arm 62 extends forward and is fixedly connected to the vehicle body 30 of the vehicle 100, the intermediate structure 61, the two spoiler arms 62 and the vehicle body 30 jointly define an installation space, and the two ends of the length direction of the front end of the active spoiler 1 are rotatably connected to the two spoiler arms 62 respectively. 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 while maintaining sufficient rigidity, and reduce the contact area with the air, thereby reducing air resistance. The roof airflow is forcibly divided into two airflows with different flow directions and sizes, one part of the airflow passes through the upper surface of the rear window glass 20, and the other part of the airflow passes through the upper surface of the spoiler body 6, meeting a variety of usage requirements.

[0057] Furthermore, if Figure 1 As shown, the spoiler body 6 further includes a limiting portion 63, one end of the limiting portion 63 in the length direction is connected to the intermediate structure 61, and the other end extends forward to be connected to the body 30 of the vehicle 100, and the limiting portion 63 is configured such that when the rear end of the active spoiler 1 swings upward, at least a portion of the lower surface of the limiting portion 63 abuts against the upper end surface of the active spoiler 1. The limiting portion 63 can limit the active spoiler 1, prevent the active spoiler 1 from excessively rotating upward, and increase the reliability of the position of the active spoiler 1.

[0058] According to the vehicle 100 of the embodiment of the present invention, Figure 1As shown, it includes the spoiler assembly 10 mentioned above.

[0059] According to the vehicle 100 of the embodiment of the present invention, 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 drives the rear end of the active spoiler 1 to swing up and down, so that the active spoiler 1 can switch between a raised state and a lowered state. When the active spoiler 1 is in the raised state, the air energy dissipation at the back of the vehicle 100 can be reduced, the wind resistance of the whole vehicle 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 rear end of the active spoiler 1 and the rear window glass 20 of the vehicle 100 are attached to the same plane, and the airflow can be directly guided to pass through the upper surface of the rear window glass 20.

When the active spoiler 1 is in the raised state, the air energy dissipation at the back of the vehicle 100 can be reduced, the wind resistance of the whole vehicle 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 rear end of the active spoiler 1 and the rear window glass 20 of the vehicle 100 are attached to the same plane, and the airflow can be directly guided to pass through 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, increase the air flow rate on the rear window glass 20, play the effect of airflow cleaning the rear window glass 20, and improve the visibility of the field of view of the rear window glass 20.

[0062] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, obtaining the driving environment and status signal of the vehicle 100 includes: obtaining the vehicle speed signal of the vehicle 100 through a vehicle speed sensor, and adjusting the working parameters of the vehicle 100 according to the different speeds of the vehicle 100 to meet the user's needs under different speed conditions; obtaining the working time of the front wiper of the vehicle 100, and then confirming the obstruction of the user's field of vision, and then facilitating the confirmation of whether the user's field of vision needs are prioritized.

[0063] In some embodiments of the present invention, determining the field of vision requirement and the priority of aerodynamic drag reduction of the vehicle 100 includes: determining whether the speed signal of the vehicle 100 exceeds a threshold value, and the threshold value can be confirmed based on parameters such as the shape of the vehicle 100; if not, the wind resistance of the vehicle 100 is not enough to generate noise, and will not affect the user experience inside the vehicle 100, and the field of vision requirement is prioritized, and the active spoiler 1 is controlled to swing downward, and the active spoiler 1 is in a lowered state, and the rear end of the active 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 through the upper surface of the rear window glass 20, and a large amount of airflow can directly flush the rear window glass 20 of the vehicle 100, thereby increasing the air flow rate on the rear window glass 20, which can achieve the effect of airflow cleaning the rear window glass 20 and improve the visibility of the field of vision of the rear window glass 20.

[0064] If yes, it is determined whether the front wiper of the vehicle 100 has been working continuously for more than 10 seconds, so as to confirm the rainfall outside the vehicle 100; if yes, the vision requirement is prioritized, the rainfall outside the vehicle 100 is heavy, and the user's vision is blocked, and the active spoiler 1 is controlled to swing downward, the active spoiler 1 is in a lowered state, and the tail end of the active 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 through the upper surface of the rear window glass 20, and a large amount of airflow can directly flush the rear window glass 20 of the vehicle 100, thereby increasing the air flow rate on the rear window glass 20, which can play a role in airflow. The effect of cleaning the rear window glass 20 is to improve the visibility of the rear window glass 20; if not, aerodynamic drag reduction is prioritized. At this time, the air group of the vehicle 100 generates greater noise, and the active spoiler 1 is controlled to swing upward. The active spoiler 1 is in a raised state. The active spoiler 1 guides the air above the top of the vehicle 100, and guides the air to the upper surface of the active spoiler 1, thereby avoiding the air from being divided into two airflows and going from the upper and lower surfaces of the spoiler assembly 10, speeding up the air flow speed on the roof, thereby reducing the air energy dissipation on the back of the vehicle 100, reducing the wind resistance of the entire vehicle, and improving the fuel economy of the vehicle 100.

[0065] Furthermore, by obtaining a rainfall signal outside the vehicle 100 through a rain sensor, it is understandable that when the external rainfall is heavy, the user's field of vision is obstructed, which may easily lead to danger, and the vehicle 100 needs to make corresponding adjustments; the front wiper can be opened or closed according to the signal transmitted by the rain sensor, avoiding the need for manual operation by the user, thereby increasing the safety of the user's driving of the vehicle 100.

[0066] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, judging the vision requirement and the priority of aerodynamic drag reduction of the vehicle 100 also includes: judging whether the front wiper of the vehicle 100 stops working for more than 15 seconds; if not, the vision requirement is prioritized, and water may be accumulated on the rear window glass 20, and the user's vision is blocked, and the active spoiler 1 is controlled to swing downward, and the active spoiler 1 is in a lowered state, and the tail end of the active 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 through the upper surface of the rear window glass 20, and a large amount of airflow can directly flush the rear window glass 20 of the vehicle 100, increasing the air flow rate on the rear window glass 20, which can play the effect of airflow cleaning the rear window glass 20, and improve the visibility of the rear window glass 20;

[0067] If yes, it is determined whether the speed of the vehicle 100 exceeds a threshold value, and the threshold value can be determined according to parameters such as the appearance of the vehicle 100; if yes, aerodynamic drag reduction is prioritized, and at this time, the air group of the vehicle 100 generates a large noise, and the active spoiler 1 is controlled to swing upward, and the active spoiler 1 is in a raised state, and the active spoiler 1 guides the air above the top of the vehicle 100, and guides the air to the upper surface of the active spoiler 1, thereby avoiding the air from being divided into two air flows and going from the upper surface and the lower surface of the spoiler assembly 10, speeding up the air flow speed on the roof, thereby reducing the air energy consumption at the back of the vehicle 100. If not, the field of vision is prioritized, and the active spoiler 1 is controlled to swing downward, the active spoiler 1 is in a lowered state, and the rear end of the active 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 through the upper surface of the rear window glass 20, and a large amount of airflow can directly flush the rear window glass 20 of the vehicle 100, increasing the air flow rate on the rear window glass 20, which can play the effect of airflow cleaning the rear window glass 20 and improve the visibility of the field of vision of the rear window glass 20.

[0068] A vehicle 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0069] Specifically, Figure 1-Figure 5 As shown, the adjustment of the position of the active spoiler 1 can be divided into two modes: manual and automatic. In the manual mode, the original position of the active spoiler 1 is directly in the pneumatic drag reduction state, that is, the raising mode. The user can raise or lower the active spoiler 1 by pressing the button in the car when necessary. In the automatic mode, the rain sensor and the speed sensor can feedback 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 in real time to control the raising or lowering position of the active spoiler 1.

[0070] When the active spoiler 1 is in the raised state, the active spoiler 1 guides the air above the roof and guides the air to the upper surface of the spoiler, thereby avoiding being divided into two air flows and going through the upper and lower surfaces of the hollow spoiler assembly 10, accelerating the air speed on the roof, thereby reducing the air energy dissipation at the back of the vehicle 100, reducing the wind resistance of the whole vehicle, and improving the fuel economy of the vehicle 100; when the active spoiler 1 is in the lowered state, the rear end of the active 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 through 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, increasing the air flow rate on the rear window glass 20, and achieving the effect of airflow cleaning the rear window glass 20 of the vehicle 100, thereby improving the field of view visibility of the rear window glass 20.

[0071] When the vehicle 100 is in the process of driving, the active spoiler 1 can be kept in the raised or lowered state by manual control, that is, it is always kept in the pneumatic drag reduction mode or the rear window glass 20 cleaning mode. The state of the active spoiler 1 can also be automatically adjusted by the automatic mode working logic. Under the driving condition, the vehicle speed reaches the threshold, and the airflow above the roof is accelerated. At this time, if the rain sensor receives the rain level signal and transmits it to the ECU, the front wiper is driven to work automatically. If the current wiper works continuously for more than 10s, it can be determined that the field of vision demand is prioritized. At this time, the field of vision of the rear window glass 20 has a higher priority than the pneumatic drag reduction function. The ECU transmits the control signal to the control motor to drive the gear 22 to rotate, driving the active rack 23. One end of the active link 4 is connected to the active rack 23, 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 be in the lowered state, and the tail end of the active spoiler 1 is in contact with the rear window glass 20, guiding the airflow to pass through the upper surface of the rear window glass 20 to wash the rainwater. When the current wiper stops moving for more than 15 seconds, it can be determined that the priority of the field of view priority is lower than the aerodynamic drag reduction function. The ECU transmits a control signal to the control motor drive to drive the active rack 23 to move upward, and the active spoiler 1 can be controlled to be in a raised state, changing to the aerodynamic drag reduction mode.

[0072] The process of raising and lowering the active spoiler 1 device is as follows: after each start or shutdown of the vehicle 100, the drive motor 21 drives the active spoiler 1 to a fully lowered or fully raised state to verify the status information of the device; during the driving process of the vehicle 100, when the drive motor 21 receives the ECU signal, the drive gear 22 rotates in a specified direction and engages with the active rack 23 connected to the active spoiler 1, thereby driving the active rack 23 to move downward in a specific direction until it moves to a specified limit state and stops. Because there is a matching relationship between the active parts of the active spoiler 1 and the active connecting rod 48, the fixing rod 3 can fix the active spoiler 1, thereby realizing the active spoiler 1 in a raised or lowered state, that is, the drag reduction function and the upper surface cleaning function of the rear window glass 20 are realized.
