Specifically, the first main groove 1011 and the second main groove 1012 are circular arc grooves, and the diameters of the first main groove 1011 and the second main groove 1012 are equal.

In some embodiments, the mounting base 110 is provided with a reference plane parallel to the first main slot 1011, the first sub slot 1021, the second sub slot 1022, and the third sub slot 1023, wherein an orthographic projection of the first main slot 1011 on the reference plane intersects with portions of the orthographic projections of the first sub slot 1021, the second sub slot 1022, and the third sub slot 1023 on the reference plane. For example, the orthographic projection of the first main groove 1011 on the reference plane can intersect with the orthographic projection of the second auxiliary groove 1022 on the reference plane, so that the whole driving device 100 is more compact in structure in the front-back direction, can be reduced in size and is convenient to mount.

In some embodiments, as shown in fig. 1 and 7, each driving arm 210 is provided with a driving hole 2101, an included angle is formed between an extension direction of the driving hole 2101 and a moving direction of the driving arm 210, the linkage arm 220 is provided with a driving post 2202, and the driving post 2202 is arranged on the driving hole 2101 in a penetrating manner. The power transmission between the driving arm 210 and the linkage arm 220 can be realized through the matching of the driving hole 2101 and the transmission column 2202, and as the curvature of the main guide groove 101 is larger than that of the auxiliary guide groove 102, when the driving arm 210 moves from the middle position of the main guide groove 101 to one end and the linkage arm 220 moves from the middle position of the auxiliary guide groove 102 along the same direction, the distance between the driving arm 210 and the linkage arm 220 is gradually increased, at the moment, the driving hole 2101 can push the transmission column 2202 to move, and the transmission column 2202 moves along the driving hole 2101 in the pushing process, so that the distance difference between the driving arm 210 and the linkage arm 220 is overcome.

For example, as shown in fig. 7, when the driving arm 210 moves in the left-right direction, an included angle is formed between the extending direction of the driving hole 2101 and the left-right direction, and the included angle may be specifically set according to circumstances, and it is only necessary to slide the driving post 2202 along the driving hole 2101 while the driving hole 2101 pushes the driving post 2202 to move.

As shown in fig. 2 and 6, the first housing 120 is provided with an auxiliary guide groove 1201, the auxiliary guide groove 1201 and the auxiliary guide groove 102 are curved in the same direction, the transmission post 2202 is provided with an auxiliary rolling body 60, and the auxiliary rolling body 60 is provided in the auxiliary guide groove 1201. That is, the auxiliary guide groove 1201 and the auxiliary rolling element 60 cooperate to guide and support the transmission column 2202, so that the reliability of the transmission column 2202 is improved, the resistance during the movement is small, and the friction is small.

In some embodiments, as shown in fig. 4 and 7, an avoiding hole 1103 is formed in the mounting base 110, the transmission post 2202 is inserted into the avoiding hole 1103, and the avoiding hole 1103 provides a space for the transmission post 2202 to move along with the linkage arm 220.

In some embodiments, the avoiding hole 1103 is a strip-shaped hole, the avoiding hole 1103 extends along the moving direction of the linkage arm 220, and the avoiding hole 1103 adopting the structure can reduce the size of the opening hole, thereby ensuring the structural strength of the mounting base 110.

In some embodiments, the auxiliary rolling element 60 may be a rolling sleeve or a roller, which is simple in structure and convenient to install.

In some embodiments, as shown in fig. 3, 4 and 5, a damping member 70 is disposed on one end of each linkage arm 220 away from the other linkage arm 220, and when the linkage arms 220 move to be close to the ends of the secondary guide slots 102, the damping member 70 can stop against the casing 10. Since the driving arm 210 moves from the middle position of the main guide groove 101 to one end, when the linkage arm 220 moves from the middle position of the auxiliary guide groove 102 to the same direction, the distance between the driving arm 210 and the linkage arm 220 is gradually increased, so that a speed difference can be formed in the process, when the linkage arm 220 moves to the tail end of the auxiliary guide groove 102, the damping part 70 can play a role in buffering and decelerating, impact abnormal sound is reduced, and safety is improved.

For example, when the two swing arms 230 drive the two air deflectors 300 to move away from each other, the damper 70 can reduce the impact of the air deflectors 300 on the air conditioning indoor unit, thereby reducing the impact noise.

Secondly, under the driving of the two swing arm assemblies 20, the two air deflectors 300 can swing towards the same side, and an air outlet is opened on the left side or the right side of the air-conditioning indoor unit 1000 to blow air outwards, in the process, because the curvatures of the main guide groove 101 and the auxiliary guide groove 102 are different, the distance between the end parts of the main guide groove and the auxiliary guide groove is gradually increased from the center to the direction extending from the two ends, when the two linkage arms 220 move in the same direction, the two linkage arms 220 form a speed difference, when the linkage arms 220 operate in the same direction through the damping piece 70, the speed of the linkage arm 220 which reaches the end part of the auxiliary guide groove 102 at first can be delayed, and further the distance difference of the two linkage arms 220 is shortened, so that when the two air deflectors 300 stop operating in the same time, the distance difference between the two air deflectors 300 is smaller or has no distance difference.

For example, the two air deflectors 300 can move leftward or rightward simultaneously, taking leftward movement as an example, in the process, the linkage arm 220 on the left side moves from the middle of the secondary guide slot 102 to the left end of the secondary guide slot 102, and the linkage arm 220 on the right side moves from the middle of the secondary guide slot 102 along the same direction, at this time, the linkage arm 220 on the left end of the secondary guide slot 102 is reached first, the damping member 70 can play a damping role, so that when the linkage arm 220 on the right side reaches the left end of the secondary guide slot 102, the distance difference between the two linkage arms 220 is relatively small or does not have a distance difference, and thus when the two air deflectors 300 move toward the same direction, no seam occurs between the joint surfaces of the two air deflectors 300, and the appearance is more attractive.

In some embodiments, as shown in fig. 3, the linkage arm 220 is provided with a mounting groove 2203, the damping member 70 is disposed in the mounting groove 2203 and partially extends out of the mounting groove 2203, that is, the damping member 70 is directly inserted into the mounting groove 2203.

In some embodiments, the damping member 70 can be an elastic member, and the elastic member can be a spring, which can achieve the damping effect and save the cost. As described above, when the linkage arm 220 on the left side reaches the left end of the secondary guide slot 102 first, the distance between the ends of the primary guide slot 101 and the secondary guide slot 102 is relatively large, so that the distance between the driving arm 210 on the left side and the linkage arm 220 on the left side is relatively large, and the movement speed of the driving arm 210 on the left side driving the linkage arm 220 on the left side is relatively large. Meanwhile, the distance between the right linkage arm 220 and the right driving arm 210 is relatively small, so that the right driving arm 210 drives the right linkage arm 220 to move at a relatively low speed. When the linkage arm 220 on the right side approaches the casing 10, the spring can firstly contact the casing 10 for buffering, the speed of the linkage arm on the right side is reduced, and at the moment, the speed of the linkage arm 220 on the left side is gradually increased, so that the two linkage arms 220 approach gradually, the distance difference between the two linkage arms can be shortened, and the two air deflectors 300 can keep a small gap or no gap.

In some embodiments, as shown in fig. 1 and 7, the driving mechanism 30 includes two driving assemblies 310, and the two driving assemblies 310 are disposed in a one-to-one correspondence with the two driving arms 210, that is, the two driving assemblies 310 can respectively drive the two driving arms 210 to move, and each driving arm 210 has an independent driving assembly 310.

When the driving arm 210 needs to be driven to move, the motor 3101 drives the gear 3102 to rotate, the gear 3102 drives the rack portion 2102 to move, and the driving arm 210 can slide along an arc-shaped track under the action of the main guide groove 101 and the main rolling body 40.
