The fourth guiding structure 310 cooperates with the second sliding slot 601 to guide the movement of the second rack structure 300.

The second rack structure 300 has full teeth as the second tooth portion 330 on the third surface, the first rack structure 200 has teeth as the first tooth portion 230 only on a part of the third surface, and the length of the second tooth portion 330 is greater than the length of the first tooth portion 230. Thus, the gear 110 may be engaged with both the first tooth portion 230 and the second tooth portion 330, or may be engaged with only the second tooth portion 330.

Preferably, the gear 110 is provided with a positioning rib 111, the positioning rib 111 is located in one tooth slot and is matched with the positioning groove 331 on the second rack structure 300, and during installation, the positioning rib 111 is installed in the positioning groove 331 of the second rack structure 300. The width of the positioning rib 111 is 1/10-1/5 of the tooth width of the conventional tooth, the tooth width of the adjacent tooth is smaller than that of the conventional tooth, and the adjacent tooth and the positioning rib 111 are spaced in the width direction of the tooth. This can prevent the positioning rib 111 from affecting the driving action of the gear 110 on the second rack structure 300.

The positioning groove 331 comprises two positioning teeth, the positioning teeth are located in one tooth socket, the positioning groove 331 is structurally matched with the positioning rib 111 of the gear 110, and the positioning groove 331 is used for installing the driving structure 100.

The positioning teeth are located on a side of the second tooth portion 330 away from the first rack structure 200.

Because the second rack structure 300 is designed to have full teeth on the third surface, 1 or 2 positioning grooves 331 can be designed on the second rack structure 300, when the air conditioner is installed, the gear 110 is matched with the positioning groove 331 close to the connection structure 3012, and when the gear 110 rotates for a circle, the positioning rib 111 can be matched with another positioning groove 331 far away from the connection structure 3012, so that the driving structure 100 can normally drive the second rack structure 300.

In addition, the first body 201 of the first rack structure 200 is a straight plate structure, the second body 301 of the second rack structure 300 is a bent structure, when the air deflector 400 is not opened, a distance L0 exists between the rotating shaft 302 of the second rack structure 300 and the rotating shaft 430 at the connection of the first rack structure 200 and the air deflector 400 in the width direction of the air deflector 400, and L0 is greater than 0mm. Thus, when the driving structure 100 simultaneously drives the first rack structure 200 and the second rack structure 300, the first rack structure 200 and the second rack structure 300 move synchronously to push out or pull back the air deflector 400; when the driving structure 100 drives the first rack structure 200 and the second rack structure 300 respectively, a distance difference is generated between the first rack structure 200 and the second rack structure 300, and the rotating shaft 302 or the rotating shaft 430 starts to push the air guiding plate 400 to rotate, so that the air guiding plate 400 rotates upward or downward.

The operation of the air deflection plate driving assembly will be described in detail with reference to fig. 13 to 17.

The first rack and the first rack structure 200 are arranged side by side, and when the air deflector 400 is in an initial state, a gap exists between the rotating shaft 302 and the rotating shaft 430 in the width direction of the air deflector 400;

after the air deflector 400 is opened, the first rack structure 200 and the second rack structure 300 synchronously move along the linear direction to push the air deflector 400 forward by a first set distance, and then the first rack structure 200 and the second rack start to perform differential motion.

The air deflection 400 assembly of the disclosed embodiment is primarily used in three modes.

In the first mode, the first rack structure 200 continues to extend forward by a second set distance, the second rack structure 300 continues to extend forward by a third set distance, the length of the second set distance is greater than that of the third set distance, and the air deflector 400 rotates counterclockwise, is in a downward opening state, and can be used for heating.

In the second mode, the first rack structure 200 continues to extend forward by a second set distance and then is stationary, and the second rack structure 300 continues to extend forward by a length greater than the second set distance, so that the air deflector 400 is in an upward opening state and can be used for cooling.

In a third mode, the first rack structure 200 continues to extend forward by a second set distance, the second rack structure 300 continues to extend forward by a fourth set distance, the length of the second set distance is equal to that of the fourth set distance, and the plane where the air deflector 400 is currently located is parallel to the plane where the air deflector 400 is located in the initial state, and can be used for supplying air up and down.

Accordingly, the air deflection panel 400 assembly mainly includes the following five states.

The first state is an initial state, the first tooth part 230 of the first rack structure 200 and the second tooth part 330 of the second rack structure 300 are both meshed with the gear 110, meanwhile, the double positioning columns at the upper ends of the first shaft body 221 of the first rack structure 200 and the third shaft body of the second rack structure 300 are respectively in contact with the upper ends of the guide rail grooves of the lower cover 500 and the upper cover 600 for limiting, the air deflector 400 is closed, and the mechanism is locked;
