At the same time, the other ends of the left and right pull wires 12 respectively drive the movable bodies 2 on the left and right sides, and the movable body 2 overcomes the force of the torsion spring 6 and opens part of the guide hole. When the motor reverses, the left and right pull wires 12 are separated from the winding wheel 10, and the movable body 2 returns to the closed state under the action of the torsion spring 6. In addition, the torsion spring 6 is installed on the first connecting rod 4, and the torsion spring 6 provides a continuous pre-tightening force to the first connecting rod 4. The first connecting rod 4 drives the driven rod to continuously provide support force to the movable body 2, so that the movable body 2 remains in a closed state.
[0085] The vehicle of this embodiment can close the air guide holes with the decorative covers on both sides when the vehicle is traveling at a low speed or parked statically, thereby improving the refinement of the vehicle. When the vehicle is traveling at a high speed, opening some of the air guide holes can reduce wind resistance or cool down components such as brake discs, which is beneficial to reducing the energy consumption of the vehicle, thereby making the vehicle have a better use effect.
