[0040] As Figure 3-4 shown, preferably in this embodiment, the air deflector structure 100 includes an air deflector 101, a bushing 102, and a telescopic rod 103 disposed within the bushing 102, and the second gear 104 is disposed on the telescopic rod 103. The air deflector 101, the bushing 102, and the telescopic rod 103 are coaxially arranged. Specifically, as Figure 4 shown, a blind hole of the air deflector is provided at one end of the air deflector 101 close to the drive unit 300, and the bushing 102 is disposed within the blind hole of the air deflector; a blind hole of the bushing is provided at one end of the bushing 102 close to the drive unit 300, and the telescopic rod 103 is disposed within the blind hole of the bushing. As Figure 2 shown, the bushing 102 includes a connecting portion and a flange portion. The connecting portion is cooperatively connected with the air deflector 101, and at least one buckle 1021 is provided on the end surface of the flange portion on one side of the connecting portion. The bushing 102 is axially limited by connecting with the air-conditioning frame through the buckle 1021.

[0041] The cross-sections of the bushing 102 and the telescopic rod 103 are polygonal. Preferably, as Figure 5-6 shown, the cross-section of the bushing 102 is hexagonal, and the cross-section of the telescopic rod 103 is quadrilateral. The cross-sections of the bushing 102 and the telescopic rod 103 are polygonal, which can realize the circumferential fixation between the telescopic rod 103 and the bushing 102, and between the bushing 102 and the air deflector 101. When the air deflector 101 works, the drive unit 300 drives the telescopic rod 103 to rotate through gear transmission, and the telescopic rod 103 drives the bushing 102 and the air deflector 101 to rotate synchronously.

[0042] Preferably in this embodiment, the air deflector structure 100 further includes a first control device for controlling the movement of the telescopic rod 103. Optionally, the first control device is an electromagnetic device or a hydraulic device. Using an electromagnetic device is beneficial to realizing the electrification control of the air-conditioning drive mechanism and can effectively improve the reliability of the control device.

[0043] In a preferred embodiment, the first control device is an electromagnetic device. The first control device includes a first electromagnet, a first iron core, a first spring, and a first coil. The first electromagnet is disposed at the bottom of the blind hole of the bushing, the first iron core is disposed at the end of the telescopic rod 103 close to the electromagnet, and both ends of the first spring are respectively fixed to the bottom of the blind hole of the bushing and the end of the telescopic rod 103 close to the first electromagnet. Specifically, when the air deflector 101 needs to work, the first electromagnet is powered off, the first spring returns from the compressed state, drives the telescopic rod 103 to extend, the first gear 302 meshes with the second gear 104, and the driving unit 300 drives the air deflector 101 to rotate; when the air deflector 101 does not need to work, the first electromagnet is powered on, adsorbs the first iron core at the end of the telescopic rod 103, drives the telescopic rod 103 to retract, the spring is in a compressed state, and the first gear 302 disengages from the second gear 104. By controlling the telescopic movement of the telescopic rod 103, the meshing or disengagement of the first gear 302 and the second gear 104 is controlled, so as to realize the driving or disengagement of the driving unit 300 from the air deflector structure 100.

[0044] As Figure 7-10 shown, preferably in this embodiment, the swing blade structure 200 includes a swing blade link 201, a worm wheel link 202, and a snap ring 204. The swing blade link 201, the worm wheel link 202, and the snap ring 204 are coaxially arranged.

[0046] In a preferred embodiment, the second control device is an electromagnetic device, which includes a second electromagnet, a second iron core, a second spring and a second coil. The second electromagnet is disposed at the bottom of the groove of the swing blade connecting rod 201. The second iron core is disposed within the snap ring 204. One end of the second spring is fixed to the bottom of the groove of the swing blade connecting rod 201, and the other end of the second spring is fixed to the annular surface of the snap ring 204 near the groove. Specifically, when the swing blade needs to work, the second electromagnet is powered off, the second spring returns from the compressed state, drives the snap ring 204 to extend, and catches the worm wheel connecting rod 202, realizing the fixed connection between the swing blade connecting rod 201 and the worm wheel connecting rod 202. The drive unit 300 drives the swing blade to rotate through the transmission of the worm wheel 203 and the worm 303. When the swing blade does not need to work, the second electromagnet is powered on, adsorbs the second iron core disposed within the snap ring 204, drives the snap ring 204 to retract, and the spring is in a compressed state, and the swing blade connecting rod 201 is disengaged from the worm wheel connecting rod 202.

[0047] For the air conditioner drive mechanism of the present invention, the air deflector structure 100 includes a telescopic rod 103 and a first control device for controlling the telescopic movement of the telescopic rod 103. When the telescopic rod 103 extends, the first gear 302 meshes with the second gear 104, and the drive unit 300 drives the air deflector 101 to rotate through gear transmission. When the telescopic rod 103 retracts, the first gear 302 disengages from the second gear 104. The swing blade structure 200 includes a snap ring 204 disposed between the swing blade connecting rod 201 and the worm wheel connecting rod 202, and a second control device for controlling the telescopic movement of the snap ring 204. When the snap ring 204 extends, the swing blade connecting rod 201 engages with the worm wheel connecting rod 202, and the drive unit 300 drives the swing blade to swing through the transmission of the worm wheel 203 and the worm 303. When the snap ring 204 retracts, the swing blade connecting rod 201 is disengaged from the worm wheel connecting rod 202. Through the above settings, it is possible to realize the separate drive of the drive unit 300 for the air deflector structure 100 or the swing blade structure 200, meeting the operating requirements of the air conditioner and improving the user experience.
