The side wall of the support plate 17 close to the side of the armrest 2 is provided with a trigger switch 36 for controlling the on/off of the fan 35, and the trigger switch 36 is used for abutting against the sun visor 24 when the sun visor 24 is turned to the vertical state.

When the sun visor 24 is needed to be used, the output shaft of the first forward and reverse rotation motor 272 drives the driving rod 271 to rotate, the supporting plate 17 is driven by the driving rod 271 to drive the guide block 18 to move vertically upwards along the guide groove 20, and meanwhile, the sun visor 24 is driven by the supporting plate 17 to move vertically upwards. Meanwhile, the output shaft of the second forward/reverse rotation motor 29 is used to drive the rotation shaft 30 to rotate forward, and the two pull wires 33 are gradually unwound.

When the sun visor 24 is extended from the mounting groove 16, the first forward/reverse rotation motor 272 and the second forward/reverse rotation motor 29 are turned off. At this time, the sun visor 24 is turned towards the direction far away from the support plate 17 under the elastic force of the torsion springs 26, and when the hinge lug 25 abuts against the limit bar 21, the sun visor 24 is in a horizontal state, so as to shield the sunlight. Meanwhile, when the sun visor 24 is disengaged from the push switch 8, the fan 35 is activated, so that the cool wind generated by the fan 35 can blow the user.

At this time, the user can drive the rotating shaft 30 to rotate in the reverse direction by the second forward/reverse rotation motor 29, and wind the two wires 33 around the rotating shaft 30. At this time, the sun visor 24 is turned toward the support plate 17 by the pulling of the two pull wires 33 to achieve the adjustment of the turning angle of the sun visor 24. Meanwhile, the output shaft of the first forward and reverse rotation motor 272 can be used to drive the driving rod 271 to rotate reversely, and then the driving rod 271 drives the supporting plate 17 to drive the guide block 18 to move vertically along the guide groove 20, so that the height of the sun visor 24 from the head of the user can be adjusted.

When the sun visor 24 needs to be stored, the second forward/reverse rotation motor 29 drives the rotating shaft 30 to rotate in the reverse direction, and the two wires 33 are wound around the rotating shaft 30. At this time, the sun visor 24 is turned toward the support plate 17 by the pulling of the two pull wires 33. When the sun visor 24 is turned to the upright position, the sun visor 24 interferes with the touch switch, and the fan 35 is automatically turned off. At the same time, the torsion springs 26 are all in a compressed state.

Subsequently, the first forward and reverse rotation motor 272 is started, the output shaft of the first forward and reverse rotation motor 272 drives the driving rod 271 to rotate in the reverse direction, the supporting plate 17 is driven by the driving rod 271 to drive the guide block 18 to move vertically downwards along the guide groove 20, and meanwhile, the sun visor 24 is driven by the supporting plate 17 to move vertically upwards. When the mounting block 31 enters the mounting groove 16, the second forward and reverse rotation motor 29 can be turned off. Subsequently, the stay 17 and the shade 24 are gradually entered into the mounting groove 16, thereby achieving the storage of the shade 24 and the stay 17.
