As shown in Figures 1 and 3, the rear spoiler with stepless adjustment of the straight length includes an outer plate 1, an extension plate 2, an inner plate 3, an actuator 4, a transmission component 5 and a motor drive component 6. Here, the extension plate 2 is arranged under the outer plate 1, and the actuator 4 is mainly arranged under the extension plate 2 and connected to the extension plate 2. The actuator 4 can drive the extension plate 2 to extend from the rear of the outer plate 1. The transmission component 5 is connected to the actuator 4 and can drive the actuator 4 to perform reciprocating linear motion. The motor drive component 6 is connected to the transmission component 5. Here, the spoiler also includes an inner plate 3 for supporting and fixing various components. The actuator 4, the transmission component 5 and the motor drive component 6 are all installed on the inner plate 3. The motor drive component 6 is connected to the electronic control part 19 of the whole vehicle communication. The vehicle working condition is judged by the feedback of the speed sensor, so that the transmission component 5 and the actuator 4 are connected to drive the extension plate 2 to move, and the position of the extension plate 2 is adjusted in real time according to the vehicle speed, so that the extension plate 2 is in the position with optimal air resistance.

Specifically, as shown in FIG2 , in order to realize the stepless adjustment of the rear spoiler, the transmission component 5 includes a driving wheel 7, a fixed pulley 8 and a wire rope 9. The two fixed pulleys 8 and the driving wheel 7 are arranged in a triangle, and the triangular arrangement makes the force transmission more effective. The output end of the motor drive component 6 is connected to the driving wheel 7. The wire rope 9 is wound between the driving wheel 7, the fixed pulley 8 and the execution component 4. The motor drive component 6 rotates to the driving wheel 7 to amplify the speed and transmits the force to the fixed pulley 8 through the wire rope 9. The fixed pulley 8 transmits the force backward to the execution component 4 and realizes reciprocating linear motion. Here, the motor drive component 6 rotates to the driving wheel 7 to amplify the speed and transmits the force to the fixed pulley 8 through the wire rope 9. The fixed pulley 8 transmits the force backward to the execution component 4 and realizes reciprocating linear motion. The moving component 6 can drive the driving wheel 7 to roll, thereby amplifying the speed. Since the wire rope 9 is connected to the wire rope 9, the wire rope 9 will move between the driving wheel 7 and the fixed pulley 8. The wire rope 9 is connected to the actuator 4. In this way, the movement of the wire rope 9 will cause the actuator 4 to move. The actuator 4 includes an actuator 10, a linear guide 11 and a linear bearing 12. In order to facilitate the installation of the actuator 4, an actuator mounting bracket 13 is provided at the lower part of the extension plate 2. A fixed bracket 14 is provided on the actuator mounting bracket 13. The actuator mounting bracket 13 is installed to the fixed bracket 14 by a screw. In this way, the position of the execution mounting bracket 13 is fixed, so that the actuator 10 is more stable when moving. The actuator 10 and the linear bearing 12 are assembled together and sleeved on the linear guide rail 11. The linear guide rail 11 is installed on the execution mounting bracket 13. The extension plate 2 and the wire rope 9 are connected to the actuator 10. A guide member 15 is provided between the extension plate 2 and the outer plate 1. A guide wheel 16 is embedded on the guide member 15. The upper and lower surfaces of the extension plate 2 are respectively matched with the guide wheel 16. In this way, the movement direction of the extension plate 2 can be guaranteed by the guide wheel 16 to prevent deviation. Here, the movement of the wire rope 9 brings When the actuator 10 moves, the linear bearing 12 can cooperate with the linear guide 11 more smoothly and slide conveniently. The actuator 10 and the linear bearing 12 make reciprocating linear motion along the linear guide 11. Since the actuator 10 moves along the linear guide 11 through the linear bearing 12, it is equivalent to achieving stepless change, so that the adjustment of the position of the extension plate 2 is more accurate. Here, since the extension plate 2 is also connected to the actuator 10, it will drive the extension plate 2 to move. The outer plate 1 covers the extension plate 2 in the initial state, and when the extension plate 2 moves, it extends from the tail of the outer plate 1 to work.

In order to conceal the internal components of the rear spoiler, the tail of the extension plate 2 is provided with a shielding hook 17, and a seal 18 is provided between the shielding hook 17 and the inner plate 3, where the seal 18 can ensure sealing and prevent damage to internal components.

The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
