The air spoiler arranged at the tail part of the vehicle is also called the tail wing of the vehicle and is a part of the aerodynamic external member of the vehicle.

Referring to fig. 3, 5 and 6, in an embodiment of the present application, the output shaft 11 of the driving motor is connected to the driving motor 10 and can rotate under the driving of the driving motor 10. The driving motor output shaft 11 is connected to the first decelerating group 20, and the second decelerating group 30 is connected to the first decelerating group 20 and connected to the spoiler 40 through the rotating shaft 50, so that the rotational motion of the driving motor output shaft 11 can drive the first decelerating group 20, the second decelerating group 30 and the rotating shaft 50 to move, and further drive the spoiler 40 to adjust the angle.

The structure illustrated in the embodiment of the present application does not specifically limit the air spoiler 100. In other embodiments of the present application, air turbulator 100 may include more or fewer components than those shown, or some components may be combined, some components may be separated, or a different arrangement of components may be used. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.
Referring to fig. 3, 5 and 6, in the embodiment of the present application, the first reduction group 20 is a gear set, and the second reduction group 30 is a transmission group in which a worm wheel 32 and a worm 31 are engaged.
It can be understood that, when the driving motor 10 is operated, the first decelerating group 20 and the second decelerating group 30 can be driven by the driving motor output shaft 11 to move, so that the spoiler 40 can be angularly adjusted, and thus the spoiler 40 can be adjusted from the non-use position to the use position, and the use position can be a plurality of angles. Illustratively, the rotation angle of the spoiler 40 may be in an angular range of 0 ° to 30 ° (including 0 ° and 30 ° as end points).
Under the combined action of the first reduction gear set 20 and the second reduction gear set 30, the power of the driving motor 10 can be transmitted to the spoiler 40 and the rotation speed thereof can be reduced, so that the worm wheel 32 can reach the rotation speed suitable for adjusting the rotation angle of the spoiler 40. In the technical scheme of the application, the first speed reduction group 20 is in gear engagement, and the second speed reduction group 30 is in worm gear 32 and worm 31 engagement, so that the failure risk caused by excessive friction due to the fact that two worm gear speed reduction devices are adopted for speed reduction in the prior art can be effectively avoided. In addition, a set of worm and gear speed reducers in the prior art is replaced by a gear set, so that transmission is more stable, the movement of the spoiler 40 is smoother and more efficient, the cost of the air spoiler can be reduced, and the overall reliability of the air spoiler 100 is improved.
The possibility of implementing the first reduction group and the connection to the second reduction group will be described in detail below with reference to fig. 2, 3, 5 and 6.
In a possible embodiment, referring to fig. 2, fig. 3 and fig. 5, the first reduction gear set 20 may include a first gear set 21, the first gear set 21 is connected to the driving motor output shaft 11, the second reduction gear set 30 is connected to the first gear set 21 and is fixedly connected to the spoiler 40 through a rotating shaft 50, the driving motor output shaft 11 transmits the power of the driving motor 10 to the first gear set 21, and the second reduction gear set 30 is connected to the first gear set 21 and transmits the power of the first gear set 21 to the spoiler 40, so that the spoiler 40 can be angularly adjusted.
Specifically, the first gear set 21 includes a first gear 211 and a second gear 212. The second reduction group 30 comprises a worm 31 and a worm wheel 32. The first gear 211 is connected to and rotates coaxially with the drive motor output shaft 11, the second gear 212 is engaged with the first gear 211, and the second gear 212 is connected to the worm 31 and rotates coaxially with the worm 31. The worm wheel 32 is engaged with the worm 31 and is rotatably connected to the spoiler 40 by the rotation shaft 50 so that the spoiler 40 can be angularly adjusted.
Accordingly, by adjusting the angle of the spoiler 40, the downforce of the air can be changed, and the stability of the vehicle 1000 in the traveling state can be improved. In addition, compared with a worm gear transmission mode, a transmission mode realized by the meshing of the first gear 211 and the second gear 212 has the characteristics of more stable transmission, smoother and more efficient movement of the spoiler 40, and can also reduce the cost of the air spoiler apparatus 100. And, gear drive's drive ratio is suitable, can make the transmission more steady for the speed reduction process of driving motor output shaft 11 is more reliable.
For example, the first gear 211 and the second gear 212 may be bevel gears. It can be understood that the first gear 211 and the second gear 212 are set as bevel gears, so that the direction of gear transmission can be adaptively adjusted, flexibility is high, and the method is favorable for adapting to application requirements in multiple scenes.
Alternatively, the first gear 211 may be a spur gear, and the second gear 212 may be a face gear, wherein a central axis of the first gear 211 is perpendicular to a central axis of the second gear 212, and the central axis of the first gear 211 may be understood as a rotation center line of the first gear 211, around which the first gear 211 can rotate. The central axis of the second gear 212 can be understood as the rotational center line of the second gear 212, around which the second gear 212 can make rotational motion. It can be appreciated that the face gear has a longer life, and thus when applied to the air turbulator 100, the life of the entire air turbulator 100 can be extended, and the maintenance cost of the air turbulator 100 can be reduced.
Alternatively, the first gear 211 may be a helical gear, and the second gear 212 may be a face gear, wherein the central axis of the first gear 211 intersects with but is not perpendicular to the central axis of the second gear 212, and the central axis of the first gear 211 may be understood as the rotation center line of the first gear 211, around which the first gear 211 can rotate. The central axis of the second gear 212 can be understood as the rotational center line of the second gear 212, around which the second gear 212 can make rotational motion.
In the present embodiment, the number of teeth of the first gear 211 may be smaller than the number of teeth of the second gear 212. Thus, when the number of teeth of the first gear 211 is smaller than that of the second gear 212, the transmission ratio of the first gear 211 to the second gear 212 is greater than 1, and the rotation speed of the second gear 212 is smaller than that of the first gear 211, so as to decelerate the rotation of the driving motor 10.
For example, the worm wheel 32 may be a hollow right circular ring structure, and the rotating shaft 50 may pass through a middle hole 321 of the worm wheel 32 and be fixedly connected with the worm wheel 32 through the middle hole 321. The central axis of the worm wheel 32 coincides with the central axis of the rotating shaft 50, and the worm wheel 32 and the rotating shaft 50 rotate synchronously, wherein the central axis of the worm wheel 32 is the rotating central line of the worm wheel 32, and the worm wheel 32 can rotate around the central axis. The central axis of the rotating shaft 50 is the rotating center line of the rotating shaft 50, around which the rotating shaft 50 can rotate. The shaft 50 and the worm wheel 32 may be an integral structure formed by assembling or integrally molding.
In addition, the unwinding helix angle of the worm 31 may be smaller than the friction angle at which the worm wheel 32 and the worm 31 contact. Therefore, when the spiral angle of the worm 31 is smaller than the friction angle between the worm wheel 32 and the worm 31, and the second reduction group 30 has a self-locking function, that is, when the worm wheel 32 and the worm 31 move in opposite directions or have a tendency to move in opposite directions, the worm wheel 32 and the worm 31 are self-locked to prevent the opposite movement.
In another possible embodiment, the same contents as those in the previous embodiment are not repeated, and the different contents from those in the previous embodiment will be described in detail below.
Referring to fig. 2, 3 and 6, the first reduction gear set 20 further includes a second gear set 22. The driving motor 10 drives the first gear set 21 to move, the second gear set 22 is connected to the first gear set 21, the second gear set 22 is connected to the second reduction gear set 30 to transmit the power of the first gear set 21 to the second reduction gear set 30, and the spoiler 40 is rotatably connected to the second reduction gear set 30 through the rotating shaft 50 to be driven to adjust the angle.
It can be understood that, when the driving motor 10 is operated, the first gear set 21, the second gear set 22 and the second reduction gear set 30 can be driven by the driving motor output shaft 11 to move, so that the spoiler 40 can be angularly adjusted, and thus the spoiler 40 can be adjusted from the non-use position to the use position, and the use position can be a plurality of angles. Illustratively, the rotation angle of the spoiler 40 may be in an angular range of 0 ° to 30 ° (including 0 ° and 30 ° as end points).
Referring to fig. 6, in the present embodiment, the air spoiler 100 further includes a transmission shaft 23. The second gear set 22 includes a third gear 221 and a fourth gear 222. The first gear 211 is connected to the driving motor output shaft 11, and the second gear 212 is engaged with the first gear 211 and connected to the third gear 221 through the rotation shaft 23. That is, the second gear 212 and the third gear 221 rotate coaxially, and the central axis of the second gear 212 coincides with the central axis of the third gear 221, wherein the central axis of the third gear 221 can be understood as the rotation center line of the third gear 221, around which the third gear 221 can rotate. The third gear 221 is engaged with a fourth gear 222, and the fourth gear 222 is connected with the worm and coaxially rotates.
Thereby, the driving motor output shaft 11 rotates the first gear 211, and the second gear 212 engages with the first gear 211 and transmits the power of the first gear 211 to the third gear 221 rotating coaxially therewith. The fourth gear 222 is in meshed connection with the third gear 221 and transmits power on to the second reduction group 30.
It can be understood that, by adding the second gear set 22 between the first gear set 21 and the second reduction gear set 30, the first gear set 21, the second gear set 22 and the second reduction gear set 30 can form three-stage reduction due to the reduction effect of the second gear set 22, so that the second gear set 22 provides an excellent buffering effect for the reduction process between the first gear set 21 and the second reduction gear set 30, and further, the rotation speed of the driving motor 10 can be more smoothly reduced to the rotation speed required by the rotation of the spoiler 40.
Illustratively, the third gear 221 and the fourth gear 222 are both spur gears.
It will be appreciated that the gear ratio of the second gear set 22 can be adjusted by adjusting the gear ratio of the third gear 221 to the fourth gear 222. The third gear 221 and the fourth gear 222 are straight gears, so that negative effects caused by axial force can be reduced, and the cost of the air turbulence device 100 is effectively reduced because the straight gears are easy to machine and manufacture.
