As shown in connection with fig. 1-12, an embodiment of the present disclosure provides an air deflection driving assembly, including a driving case 400 and a rack, wherein the driving case 400 is configured with a sliding space in which a restraining groove is provided in a length direction; the rack is suitable for being in driving connection with the air deflector 100 and is at least partially positioned in a sliding space, a first plane of the rack is provided with teeth, a second plane is outwardly provided with a guide post 230, a third plane is provided with a convex rib 240 along the length direction of the rack, the second plane is adjacent to the first plane, and the third plane is opposite to the first plane; wherein, when the rack slides in the sliding space, the guide post 230 slides in the constraint groove to limit the movement of the rack to a linear movement, and the rib 240 is in sliding contact with the bottom of the sliding space.

In the embodiment of the present disclosure, the rack slides in the sliding space of the driving box 400, and the guide post 230 of the rack is positioned in the restraining groove, thereby limiting the movement of the rack to a linear movement. The top surface of the rack is provided with a rack, the side edge of the rack is provided with a guide post 230 in an extending mode, and the bottom of the rack is provided with a convex rib 240 in a downward extending mode. The rib 240 extends along the length direction of the rack, and when the rack slides, the rib 240 slides along the length direction and is in sliding contact with the bottom of the sliding space.

With such a configuration, the friction between the rack and the driving box 400 can be reduced, so that the rack slides more smoothly, which is beneficial for the rack to drive the air deflector 100 to move.

Optionally, the number of the ribs 240 is plural, and the plurality of ribs 240 are disposed at intervals on the third plane of the rack.

The ribs 240 are disposed in parallel, and the length direction is along the sliding direction of the rack. The plurality of ribs 240 are arranged, so that the sliding resistance of the rack can be further reduced, and the rack is beneficial to driving the air deflector 100 to rotate.

Optionally, the number of racks is two, and the two racks are a first rack 210 and a second rack 220, respectively, the first rack 210 is drivingly connected to the first position of the air deflector 100, and the second rack 220 is drivingly connected to the second position of the air deflector 100; wherein, when the first rack 210 and the second rack 220 move in the same direction, the air deflector 100 is extended or retracted, and when the first rack 210 and the second rack 220 move in a differential direction, the air deflector 100 is turned over.

In the embodiment of the present disclosure, the first rack 210 and the second rack 220 move linearly in the sliding space, and the moving direction is toward or away from the wind deflector 100. The first end of the first rack 210 is rotatably coupled to a first position of the air deflector 100, and the first end of the second rack 220 is rotatably coupled to a second position of the air deflector 100. The first end of the first rack 210 and the first end of the second rack 220 are both on the outer side with respect to the air conditioner. The first and second positions of the deflector 100 are not the same position. When the first rack 210 and the second rack 220 are simultaneously moved outward, the air guide plate 100 is extended to open the air outlet of the air conditioner. When the first rack 210 and the second rack 220 simultaneously move inward, the air guide plate 100 is retracted to close the air outlet of the air conditioner. With the adoption of the arrangement mode, the air deflector 100 can be driven to stretch and overturn through the first rack 210 and the second rack 220, so that various air guiding modes are realized, and convenience is brought to users.

Optionally, the air deflector driving assembly further comprises a driving wheel 320, including a first gear 321 and a second gear 322 which coaxially rotate, wherein the diameter of the first gear 321 is larger than the diameter of the second gear 322; wherein the teeth of the first rack 210 are engaged with the first gear 321 and the second rack 220 is engaged with the second gear 322.

The driving wheel 320 is a double gear, and includes a first gear 321 and a second gear 322, and the first gear 321 and the second gear 322 are concentric and coaxial. The driving motor 310 is drivingly connected to the first gear 321 or the second gear 322 and can drive the first gear 321 and the second gear 322 to rotate simultaneously. The first gear 321 is engaged with the first rack 210, and the second gear 322 is engaged with the second rack 220. The diameter of the first gear 321 is larger than the diameter of the second gear 322, and when the driving motor 310 outputs power, the angular speeds of the first gear 321 and the second gear 322 are the same, and the linear speed of the first gear 321 is larger than the linear speed of the first gear 321. So that the first rack 210 and the second rack 220 can move in the same direction and differentially. When the driving wheel 320 rotates in the first direction, the air deflector 100 extends and turns in the first direction; when the driving wheel 320 rotates in the second direction, the wind deflector 100 is turned over and retracted in the second direction. With such an arrangement, what is needed is that section of wind-guiding angle. In addition, the driving wheel 320 is a double gear, and the driving wheel 320 can be driven to rotate by one motor, so that the first rack 210 and the second rack 220 can move in a differential mode, the motor is reduced, the structure of the air deflector driving assembly is simplified, and the cost of the air deflector driving assembly is reduced.

Optionally, the first portion 211 of the first rack 210 is engaged with the first gear 321, the second portion 212 is not engaged with the first gear 321, and the first portion 211 of the first rack 210 is adjacent to the air deflector 100; wherein, when the driving wheel 320 rotates, in the first stage, the first portion 211 of the first rack 210 is meshed with the first gear 321, the second rack 220 is meshed with the second gear 322, the speed of the first rack 210 is greater than the speed of the second rack 220, and the air deflector 100 extends outwards and turns in the first direction; in the second stage, the second portion 212 of the first rack 210 corresponds to the first gear 321, the first rack 210 is stationary, the second rack 220 extends outward, and the air deflector 100 is flipped in the second direction.

The operating states of the wind deflector 100 include a closed state, a first open state, and a second open state. The air deflection 100 is switched from the closed state to the first open state during the first stage of rotation of the drive wheel 320, and the air deflection 100 is switched from the first open state to the second open state during the second stage of rotation of the drive wheel 320. Taking the example that the air deflector driving assembly is applied to an indoor hanging machine, when the working state of the air deflector 100 is a closed state, the air conditioner is in a closed mode; when the air deflector 100 is in the first open state, the air outlet mode of the air conditioner is downward air outlet, and the operation mode of the air conditioner is heating mode; when the air deflector 100 is in the second open state, the air outlet direction of the air conditioner is the upward and downward air outlet simultaneously, the air outlet mode of the air conditioner is the anti-direct-blowing mode, and the operation mode of the air conditioner is the heating mode or the refrigerating mode. When the air conditioner operates in the heating mode, hot air blown out through the air conditioner is blown to a lower space in a room under the air guide effect of the air guide plate 100. The density of the hot air is smaller than that of the cold air, and the hot air floats upwards under the effect of the difference of the densities of the cold air and the hot air, so that the indoor temperature is uniformly changed, and a user can feel the heating effect of the air conditioner more clearly and rapidly. In order to avoid discomfort of users caused by direct blowing of the air conditioner, when the air deflector 100 is in the second open state, the air deflector 100 is perpendicular to the air outlet direction of the air outlet and is at a certain distance from the air outlet. In this way, the air blown out through the air outlet of the air conditioner is blown out into the room at the same time upward and downward at the stopper of the air guide plate 100. Under the mode, the direct blowing user of the air conditioner can be effectively avoided, and the direct blowing prevention function is realized.

In the first stage of rotation of the driving wheel 320, when the wind deflector 100 is switched from the closed state to the first open state, the stroke of the first rack 210 is greater than the stroke of the second rack 220, and the first rack 210 moves for the same time as the second rack 220, so that the speed of the first rack 210 is greater than the speed of the second rack 220.

When the air deflector 100 is switched from the first open state to the second open state, the second rack 220 moves outward and the stroke is larger than that of the first rack 210. The first rack 210 remains stationary and the second rack 220 moves outwardly, at which time the air deflection 100 is flipped in a second direction, which is opposite to the first direction. It should be noted that, when the air-out mode of the air conditioner is any air-out mode, the air-out mode can be swung by the reciprocating motion of the first rack 210 and/or the second rack 220, so as to increase the air-out range of the air conditioner and improve the uniformity of indoor refrigeration or heating.

The driving wheel 320 is a double gear, and includes a first gear 321 and a second gear 322, and the first gear 321 and the second gear 322 are concentric and coaxial. The driving motor 310 is drivingly connected to the first gear 321 or the second gear 322 and can drive the first gear 321 and the second gear 322 to rotate simultaneously. The first gear 321 is engaged with the first rack 210, and the second gear 322 is engaged with the second rack 220. The diameter of the first gear 321 is larger than the diameter of the second gear 322, and when the driving motor 310 outputs power, the angular speeds of the first gear 321 and the second gear 322 are the same, and the linear speed of the first gear 321 is larger than the linear speed of the first gear 321. So that the first rack 210 and the second rack 220 can move in the same direction and differentially.

The first portion 211 of the first rack 210 is configured with teeth to engage with the first gear 321, and the second portion 212 is not engaged with the first gear 321. The first portion 211 is adjacent to a first end of the first rack 210, i.e., adjacent to the air deflection 100, and the second portion 212 is adjacent to a second end of the first rack 210. When the air deflector 100 is switched from the closed state to the first open state, the position where the first gear 321 engages with the first rack 210 is moved from the first end to the second end of the first portion 211 of the first rack 210. That is, the first gear 321 moves relative to the first rack 210 from the first portion 211 of the first rack 210 to the second portion 212 of the first rack 210. The first rack 210 is disengaged from the first gear 321. The first rack 210 remains stationary during the switching of the damper 100 from the first open state to the second open state and from the second open state to the third open state. The first end of the first rack 210 provides a pivot for the air deflector 100, and the second rack 220 moves outwards to drive the air deflector 100 to turn over. Alternatively, the first portion 211 of the first rack 210 is disengaged from the first gear 321, and the first rack 210 is maintained in the rest position by a stopper or friction force.

With the air deflector driving assembly provided by the embodiment of the present disclosure, the first rack 210 is only provided with a tooth form at the first portion 211, the first rack 210 is controlled to move or be stationary by the engagement and disengagement of the first gear 321 of the driving wheel 320 and the first portion 211 of the first rack 210, the first rack 210 and the second rack 220 can be simultaneously driven by the driving wheel 320, and only one motor is required to drive the driving wheel 320 to bidirectionally rotate, so that the volume of the air deflector driving assembly is reduced, and the cost of the air deflector driving assembly is reduced; the air deflector 100 is driven to extend outwards and turn over through the first rack 210 and the second rack 220, the air outlet of the air conditioner is performed in a state that the air deflector 100 extends out, the air deflector 100 is at a certain distance from the air outlet, the air blown out from the air outlet can deflect under the action of the air deflector 100 after a certain distance, the resistance of the air deflector 100 to the wind speed can be reduced, meanwhile, the air outside the air outlet flows together with the air deflector 100 under the action of the injection of the air blown out from the air outlet, and the air outlet capacity of the air conditioner is improved; the angle of the air deflector 100 is adjusted through the first rack 210 and the second rack 220, so that the air outlet mode of the air conditioner can be better matched with the running mode of the air conditioner and the requirements of users, and the use experience of the users is improved.

Optionally, in a third stage of rotation of the drive wheel 320, the first rack 210 is stationary, the second rack 220 continues to move outwardly, and the air deflection 100 continues to turn in the second direction.

Taking an indoor on-hook as an example, when the air deflector 100 is in the second open state, the air outlet direction of the air conditioner is the upward and downward air outlet simultaneously, the air outlet mode of the air conditioner is the direct blowing preventing mode, and the operation mode of the air conditioner is the heating mode or the refrigerating mode. The second rack 220 continues to move outwardly and the air deflection 100 switches from the second open condition to the third open condition. When the air deflector 100 is in the third open state, the air outlet direction of the air conditioner is upward air outlet, and the operation mode of the air conditioner is a cooling mode. In the cooling mode, cool air blown out through the air conditioner is blown to an upper space in the room. The density of the cold air is greater than that of the hot air, and the cold air moves downwards under the effect of the difference of the densities of the cold air and the hot air, so that the indoor temperature can be uniformly changed, and a user can feel the refrigerating effect of the air conditioner more clearly and rapidly.

Alternatively, the air guide plate 100 is turned over a first predetermined angle in the first direction during the first stage of rotation of the driving wheel 320, the air guide plate 100 is turned over a second predetermined angle in the second direction during the second stage of rotation of the driving wheel 320, and the air guide plate 100 is turned over a third predetermined angle in the second direction during the third stage of rotation of the driving wheel 320.

The motion of the deflector 100 can be considered as a combination of an outward motion and a turning motion. With the second position of the air deflector 100 as a reference point, the distance of the air deflector 100 moving outwards is equal to the stroke of the second rack 220, and the turning motion is to turn around by using the first end of the second rack 220 as a rotation axis and relying on the stroke difference between the first rack 210 and the second rack 220. The stroke of the second rack 220 determines the distance of the outward movement of the air guide plate 100, and the difference in the strokes of the first rack 210 and the second rack 220 determines the angle at which the air guide plate 100 is turned over. Illustratively, the first preset angle is 30 degrees to 90 degrees and the second preset angle is 30 degrees to 90 degrees. Preferably, the second preset angle is equal to the first preset angle. In this way, when the air deflector 100 is in the second open state, the same angle is kept with the air outlet of the air conditioner when the air deflector is in the closed state, so that the direct blowing preventing function can be better realized. The third preset angle may be determined by a stroke difference between the second rack 220 and the first rack 210, for example, the third preset angle is 30 degrees to 90 degrees.

The stroke of the first rack 210 is L1, the stroke of the second rack 220 is L2, L is the distance between the first position and the second position of the air deflector 100 in the direction perpendicular to the movement direction of the first rack 210 or the second rack 220, and when the connecting line between the first end of the first rack 210 and the first end of the second rack 220 is approximately regarded as the turning angle θ1 of the air deflector 100, the stroke L1 of the first rack 210, the stroke L2 of the second rack 220 and the turning angle θ of the air deflector 100 satisfy the following relationship:

tanθ＝(L1-L2)/L

Optionally, the air deflector driving assembly further includes a pushing shaft 350 and a driving plate 340, wherein the pushing shaft 350 extends from an end surface of the driving wheel 320 along an axial direction of the driving wheel 320, and the first pushing shaft 351 performs a circular motion when the driving wheel 320 rotates; a driving plate 340 fixed to the first rack 210 and opposite to an end surface of the driving wheel 320, the driving plate 340 being configured with a driving groove 341; before the first portion 211 of the first rack 210 is disengaged from the first gear 321, the shaft 350 is pushed into the driving recess 341 to continue the outward movement of the first rack 210 to the rest position and remain stationary.

Alternatively, the first portion 211 of the first rack 210 is configured with teeth that mate with the first gear 321, and the second portion 212 of the first rack 210 is not in contact with the first gear 321.

Taking the first rack 210 being laterally disposed and having teeth formed on the top end as an example, the first portion 211 is provided with teeth, the second portion 212 is lower than the first portion 211, and the first rack 210 is not in contact with the first gear 321 during rotation of the driving wheel 320 and movement of the first rack 210. Therefore, the first gear 321 can rotate to move the first rack 210 in the process of driving the second rack 220 by the driving wheel 320, so as to avoid malfunction of the first rack 210 and improve the working accuracy of the air deflector driving assembly.

The pushing shaft 350 is disposed at an end surface of the driving wheel 320, the driving plate 340 is fixed to the first rack 210, and the driving plate 340 is configured with a driving groove 341. The driving wheel 320 extends in the circumferential direction of the driving wheel 320 and is not located at the center of the driving wheel 320. The driving wheel 320 rotates to push the shaft 350 to perform a circular motion. Push-out

The moving shaft 350 cooperates with the driving groove 341 to push the driving plate 340 to move. The driving plate 340 is fixed to the first rack 210 to move only linearly with the first rack 210. Accordingly, the pushing shaft 350 cooperates with the driving groove 341 to push the driving plate 340 to make a linear motion, thereby driving the first rack 210 to make a linear motion.

In order to better move the first gear 321 from the first portion 211 of the first rack 210 to the second portion 212 of the first rack 210 during the switching of the air guide plate 100 from the closed state to the first open state, the pushing shaft 350 is pushed into the driving groove 341 to form a force with the driving of the first gear 321 before the first gear 321 is out of engagement with the first portion 211 of the first rack 210, so that the first rack 210 is driven to continue to move outwardly to the rest position.

It should be noted that, the driving shaft 350 and the driving recess 341 are also reversible for driving the first rack 210. During the switching of the wind deflector 100 from the first opened state to the closed state, the push shaft 350 reversely rotates in the driving groove 341 to move the first rack 210 inward, and the first gear 321 moves from the second portion 212 of the first gear 321 to the first portion 211 of the first gear 321 to reengage the first gear 321. The pushing shaft 350 is separated from the driving groove 341, and the first gear 321 drives the first rack 210 to move inward to the initial position of the first rack 210.

The provision of the guide slot and drive shaft to urge the first rack 210 bi-directionally may complement the cooperation of the first rack 210 and the first gear 321 to better move the first rack 210 to the rest position and remain stationary. Specifically, the first rack 210 is driven to move in a process of disengaging the first gear 321 from the first rack 210 and reengaging the first gear 321 with the first rack 210. In this manner, the first rack 210 moves more clearly and the air deflection drive assembly operates more reliably.

Alternatively, the pushing shaft 350 extends from the end surface of the first gear 321 in a direction away from the second gear 322.

The first gear 321 is larger than the second gear 322, the pushing shaft 350 is configured on the end surface of the first gear 321 and extends in a direction away from the second gear 322, that is, the second gear 322 is located on one side of the first gear 321, and the pushing shaft 350 is located on the other side of the first gear 321, so that the interference between the rotation of the pushing shaft 350 and the first rack 210 or the second rack 220 can be avoided. In addition, the end surface area of the first gear 321 is larger, and the pushing shaft 350 is disposed on the end surface of the first gear 321 and may be disposed near the edge, so that the pushing shaft 350 obtains a larger linear velocity during the rotation of the driving wheel 320, and thus the first rack 210 is pushed to move bi-directionally and be kept at a static position by the driving plate 340.

Alternatively, the pushing shaft 350 includes a first pushing shaft 351 and a second pushing shaft 352, wherein the second pushing shaft 352 has a first motion phase difference with the first pushing shaft 351; the driving groove 341 includes a first driving groove 342 and a second driving groove 343, wherein the first driving groove 342 is matched with the first pushing shaft 351, before the first portion 211 of the first rack 210 is out of the matched with the first gear 321, the first pushing shaft 351 enters the first driving groove 342, and the first driving groove 342 converts the circular motion of the first pushing shaft 351 into the linear motion of the first rack 210 so as to enable the first rack 210 to move outwards to a rest position; the second driving groove 343 is annular and is matched with the second pushing shaft 352, before the first pushing shaft 351 is separated from the first driving groove 342, the second pushing shaft 352 enters the second driving groove 343, and the first rack 210 is kept at a static position when the second pushing shaft 352 moves circularly in the second driving groove 343.

The first motion phase difference exists between the first pushing shaft 351 and the second pushing shaft 352, so that the first pushing shaft 351 and the second pushing shaft 352 can be prevented from being in motion interference with the driving groove 341 of the driving plate 340.

The first driving groove 342 cooperates with the first pushing shaft 351 to make the first rack 210 move in a straight line. Specifically, during the switching of the air deflection 100 from the closed state to the first open state, the first pushing shaft 351 enters the first driving groove 342 before the first gear 321 is out of engagement with the first portion 211 of the first rack 210. The first driving groove 342 converts the circular motion of the first pushing shaft 351 into the linear motion of the driving plate 340, thereby driving the first rack 210 to protrude outward, and the first gear 321 is disengaged from the first portion 211 of the first rack 210.

The second driving groove 343 and the second pushing shaft 352 cooperate to maintain the first rack 210 in the rest position. The second driving groove 343 is annular, and when the driving wheel 320 rotates, the movement trace of the second pushing shaft 352 is circular movement with the same diameter as the second driving groove 343. During the switching of the air deflector 100 from the closed state to the first open state, the second pushing shaft 352 enters the second driving groove 343 before the first pushing shaft 351 exits from the first driving groove 342. During the switching of the wind deflector 100 from the first opened state to the second opened state, the second pushing shaft 352 rotates in the second driving groove 343, thereby restricting the sliding of the first rack 210, and maintaining the first rack 210 in the stationary position.

Alternatively, the driving wheel 320 rotates in the first direction while the first pushing shaft 351 is in the first driving groove 342; the first rack 210 moves inward and the first rack 210 moves outward as the drive wheel 320 rotates in the second direction.

In a first stage of rotation of the driving wheel 320, the first rack 210 moves linearly. With reference to the first rack 210, the driving wheel 320 moves from the first end of the first rack 210 to the second end of the first rack 210, and the first gear 321 moves from the first end of the first portion 211 of the first rack 210 to the second end of the first portion 211 of the first rack 210. When the first gear 321 moves to the second end of the first portion 211 of the first rack 210, the first pushing shaft 351 enters the first driving groove 342 before being out of engagement with the first portion 211 of the first rack 210. The driving wheel 320 continues to rotate, the first gear 321 is disengaged from the first rack 210, and the first pushing shaft 351 moves from the first end of the first guide groove to the second end of the first guide groove, thereby driving the first rack 210 to continue to move outwards to the rest position. When the wind deflector 100 is switched from the first opened state to the closed state, the first pushing shaft 351 moves from the second end of the first driving groove 342 to the first end of the first driving groove 342, thereby driving the first rack 210 to move inward until the first gear 321 is reengaged with the first portion 211 of the first rack 210. The driving wheel 320 continues to rotate, the first pushing shaft 351 leaves the first driving groove 342 from one end of the first driving groove 342, and the first gear 321 drives the first rack 210 to move to the initial position. With this arrangement, the first pushing shaft 351 and the first driving groove 342 cooperate to disengage the first portion 211 of the first rack 210 from the first gear 321 or to reengage the first portion 211 of the first gear 321 with the first gear 321, and the driving of the first gear 321 is engaged to better drive the first rack 210 for controlled movement.

Alternatively, the first rack 210 remains stationary while the drive wheel 320 rotates in the first direction and rotates in the second direction while the second push shaft 352 is within the second drive recess 343.

When the second pushing shaft 352 rotates in any direction in the second driving groove 343, the shape of the second driving groove 343 corresponds to the rotation track of the second pushing shaft 352, the driving plate 340 remains stationary, and the first rack 210 also remains stationary. This may better hold the first rack 210 in a stationary position, thereby providing a stable fulcrum for rotation of the deflector 100.

Optionally, the first driving groove 342 is arc-shaped and protrudes toward the first rack 210, and the first pushing shaft 351 enters or leaves the first driving groove 342 when being at a first distance from the first rack 210, and the first distance is less than or equal to the radius of the first gear 321.

The first driving groove 342 is adjacent to the first rack 210, that is, the first pushing shaft 351 enters and exits the first driving groove 342 at a position adjacent to the first rack 210. The linear velocity of the first pushing shaft 351 along the length direction of the first rack 210 at a position close to the first rack 210 is greater, so that the circular motion of the first pushing shaft 351 can be better converted into the linear motion of the driving plate 340, and the first rack 210 is driven to move. The first driving groove 342 is arc-shaped protruding toward the first rack 210, the movement track of the first pushing shaft 351 is relatively close, and the movement of the first guiding shaft in the first driving groove 342 can be smoother. The first distance is less than or equal to the radius of the first gear 321, and the maximum distance of the first driving groove from the first rack 210 is less than the radius of the first gear 321. During this distance, the speed of the first pushing shaft 351 along the length direction of the first rack 210 is larger, so that the first pushing shaft can be matched with the first driving groove 342 better to drive the first rack 210 to move.

Alternatively, the opening of the second driving groove 343 is remote from the first rack 210.

When the first pushing shaft 351 is located in the first driving groove 342, the first driving groove 342 is located at the proximal end, and the opening of the second driving groove 343 is located at the distal end, with reference to the first rack 210. Thus, on the one hand, the distance between the first pushing shaft 351 and the second pushing shaft 352 is far, and the movement of the two is not easy to interfere, specifically, when the first pushing shaft 351 slides in the first driving groove 342, the second pushing shaft 352 is at the distal end and does not interfere with the side wall of the first driving groove 342. Likewise, the second pushing shaft 352 is just like the second driving groove 343 from the distal end before the first pushing shaft 351 is separated from the inside of the first driving groove 342, and the first pushing shaft 351 does not interfere with the side wall of the second driving groove 343.

Alternatively, the first pushing shaft 351 and the second pushing shaft 352 are equidistant from the center of the driving wheel 320.

After the second pushing shaft 352 enters the second driving groove 343, the first pushing shaft 351 also enters the second driving groove 343 along with the rotation of the driving wheel 320, and keeps the first rack 210 in a stationary position together with the first driving groove 342.

The first pushing shaft 351 and the second pushing shaft 352 are both located in the second driving groove 343, so that the first rack 210 can be better kept in the rest position, and the first end of the first rack 210 can be used as a pivot point for rotating the air deflector 100 more firmly.

Alternatively, one of the first rack bar 210 and the second rack bar 220 is configured with a sliding groove 250 in a length direction, and the other is provided with a sliding portion 260, and the sliding portion 260 slides within the sliding groove 250 to slidably connect the second rack bar 220 to the first rack bar 210.

Optionally, a first plane of the first rack 210 is configured with teeth, and a second plane is recessed inward to form a first runner 250 along a length of the first rack 210, the second plane being adjacent to or opposite to the first plane; the second rack 220 is provided with a sliding portion 260 extending outwards, and the sliding portion 260 slides in the first sliding groove 250 of the first rack 210, so that the second rack 220 is slidably connected to the first rack 210.

The first plane of the first rack 210 is configured with teeth to be engaged with the gear, the second plane is configured with a sliding groove 250 extending in a length direction of the first rack 210, the second rack 220 is configured with a sliding portion 260, and the second rack 220 is slidably coupled to the first rack 210 through the sliding portion 260. Thus, the sliding direction of the first rack 210 is along the length direction of the first rack 210, the sliding direction of the second rack 220 is also along the length direction of the first rack 210, and the first rack 210 and the second rack 220 slide in parallel. On the one hand, the parallel sliding of the first rack 210 and the second rack 220 is beneficial to driving the air deflector 100 to stretch out and draw back and turn over, on the other hand, the second rack 220 is connected with the first rack 210 in a sliding manner, and a sliding track is not required to be additionally arranged for the second rack 220, so that the volume of the air deflector driving assembly is reduced, the wind resistance of the air deflector driving assembly is reduced, and the air outlet effect of the air conditioner is improved.

Alternatively, the first plane of the second rack 220 is configured with teeth, and the sliding portion 260 is disposed outwardly from a second plane of the second rack 220, which is a plane adjacent to or opposite to the first plane.

The first plane of the second rack 220 is used for being matched with a gear, the sliding part 260 is arranged on the surface, where no teeth are formed, of the second rack 220, the sliding part 260 and the first rack 210 cannot interfere with the matching of the gear and the second rack 220, and the gear is favorable for driving the second rack 220 to move better.

Optionally, the second rack 220 comprises a body 221 and an extension 222, wherein the body 221, the first plane, is configured with teeth; an extension portion 222 extending from a third plane of the body 221 in a direction away from the body 221, the third plane being a plane opposite to the first plane; wherein the sliding portion 260 extends outward from the side of the extending portion 222.

The body 221 of the second rack 220 is used for being driven by a gear to drive the air deflector 100 to move, and the extension 222 of the second rack 220 is used for being matched with the sliding groove 250 of the first rack 210 to provide a sliding track for the second rack 220. Taking the first plane as an example of the upper surface of the first gear 321, the extension portion 222 extends downward from the lower surface of the body 221, and the sliding portion 260 extends outward from the side edge of the extension portion 222 into the chute 250 of the first gear 321. An extension 222 is provided to allow for better sliding connection of the second rack 220 with the first rack 210.

Optionally, the length of the extension 222 is less than the length of the body 221 of the first rack 210.

In order to drive the air guide plate 100, the length of the second rack 220 is longer, and the travel of the second rack 220 is shorter when the air guide plate 100 moves, and the length of the extension 222 is smaller than the length of the body 221 of the second rack 220, so that the volume of the second rack 220 can be reduced, and the weight of the second rack 220 can be reduced.

Alternatively, the sliding portion 260 has a larger dimension along the length direction of the first rack 210 than a dimension perpendicular to the length direction of the first rack 210.

In this way, the sliding portion 260 is not easy to turn when sliding in the sliding groove 250 of the first rack 210, which is beneficial to the parallel movement of the first rack 210 and the second rack 220, so as to better drive the air deflector 100 to move.

Alternatively, the sliding part 260 includes a first slider 261 and a second slider 262, wherein the second slider 262 is spaced apart from the first slider 261.

The first sliding block 261 and the second sliding block 262 are arranged, so that the sliding part 260 can be prevented from turning in the sliding groove 250, and the parallel movement of the first rack 210 and the second rack 220 is facilitated, and the air deflector 100 is driven to move better.

Optionally, the air guide plate driving assembly further includes a first connection part 500 and a second connection part 600, wherein the first connection part 500 extends inward from the first position of the air guide plate 100, the first connection part 500 is provided with a rotation hole 510, and the first end of the first rack 210 is rotatably connected to the first connection part 500 through a first rotation shaft; the second connection part 600 extends inwards from the second position of the wind deflector 100, the second connection part 600 is provided with a direction-adjusting track groove 610, the first end of the second rack 220 is rotationally connected to the second connection part 600 through a second rotation shaft, and when the first rotation shaft rotates in the rotation hole 510, the second rotation shaft rotates or slides in the direction-adjusting track groove 610.

The first connection part 500 is fixed to a first position of the wind deflector 100, and the second connection part 600 is fixed to a second position of the wind deflector 100, the first and second positions being different positions.

The first connection portion 500 is provided with a rotation hole 510, and an axial direction of the rotation hole 510 is along a length direction of the air deflector 100. The first end of the first rack 210 is provided with a first rotation shaft, which rotates in the rotation hole 510, so that the first rack 210 is rotatably connected to the wind deflector 100.

The second connection portion 600 is provided with a direction-adjusting rail groove 610, and an axial direction of the direction-adjusting rail groove 610 is along a length direction of the wind deflector 100. The first end of the second rack 220 is provided with a second rotation shaft. The second rotation shaft rotates in the direction-adjusting rail groove 610, thereby rotatably connecting the second rack 220 to the wind deflector 100. At the same time, the second rotating shaft can also slide in the direction-adjusting track groove 610, so that the first rack 210 and the second rack 220 can better drive the wind deflector 100 to rotate.

Specifically, the first rack 210 and the second rack 220 slide in parallel, and the distance L between the first rotation axis and the second rotation axis in the direction perpendicular to the length direction of the first rack 210 remains unchanged. When the wind deflector 100 rotates, an included angle θ2 formed by a connecting line of the first rotation axis and the second rotation axis and the first rack 210 changes, and a distance between the first rotation axis and the second rotation axis is L3, where

L＝L3*sinθ2

It can be seen that the distance between the first rotation axis and the second rotation axis varies with the rotation of the air deflection plate 100. Accordingly, the first connection part 500 is provided with the direction-adjusting rail groove 610, and the first rotation shaft slides in the direction-adjusting rail groove 610 when the air guide plate 100 is driven to rotate, so that the distance between the first rotation shaft and the second rotation shaft is adaptively adjusted while the air guide plate 100 is driven to rotate.

With the air deflector driving assembly provided by the embodiment of the present disclosure, the first end of the first rack 210 and the first end of the second rack 220 are both rotatably connected to the air deflector 100, so that the air deflector 100 can be driven to move to realize multiple air guiding modes; the second connection part 600 is provided with a direction-adjusting rail groove 610, so that the air deflector 100 can be turned over by a larger angle, and the air conditioner can better discharge air.

Optionally, the direction-adjusting track groove 610 includes a first groove section 611 and a second groove section 612, wherein the first groove section 611 is obliquely arranged, and a distance between the first end and the air deflector 100 is smaller than a distance between the second end and the air deflector 100; the second groove section 612 is obliquely arranged, the first end of the second groove section 611 is communicated with the second end of the first groove section 611, the distance between the first end and the air deflector 100 is larger than the distance between the second end and the air deflector 100, and the connection position of the first groove section 611 and the second groove section 612 is inwards protruded.

When the wind deflector 100 is in the initial position, the second rotation shaft is positioned at the first groove section 611 of the steering rail groove 610. As the first rack 210 and the second rack 220 move differentially, the distance between the first rotation shaft and the second rotation shaft increases, and the second rotation shaft slides from the first groove section 611 to the second groove section 612. The connection position of the first groove section 611 and the second groove section 612 protrudes inward to play a role of positioning, which is advantageous for maintaining the air deflector 100 in the initial position. Specifically, the sliding resistance of the second rotating shaft increases when the second rotating shaft moves to the connection between the first groove section 611 and the second groove section 612, and thus, there is a short pause in the first groove section 611, and accordingly, the rotation of the air deflector 100 also changes at a relatively significant speed. Thus, the motion of the air deflector 100 can be clearer, and the air deflector 100 can be kept at the initial position.

The first groove section 611 is obliquely arranged, and the distance between the end far from the second groove section 612 and the air deflector 100 is smaller than the distance between the second end near to the second groove section 612 and the air deflector 100. Thus, when the second rack 220 moves, the whole movement of the second rack 220 is used for driving the air deflector 100 to turn, and meanwhile, the distance between the first end of the second rack 220 and the air deflector 100 becomes longer, and under the combined action of two factors, the second rack 220 turns the air deflector 100. The air deflection 100 may be flipped over a greater angle when the second rack 220 is moved the same distance than when the second slot segment 612 is disposed parallel to the air deflection 100. With this arrangement, the air guide plate 100 can be opened quickly. Likewise, the air guide plate 100 can be quickly closed when the air guide plate 100 is closed.

The difference in travel between the first rack 210 and the second rack 220 is a first distance when the second rotational shaft is within the second slot segment 612. The stroke difference between the first rack 210 and the second rack 220 is a second distance when the second rotation shaft is in the third groove section 613. The second distance is greater than the first distance.

The second slot segment 612 is obliquely arranged, and the distance between the end close to the first slot segment 611 and the air deflector 100 is larger than the distance between the end close to the second slot segment 612 and the air deflector 100. Thus, as the second rack 220 moves, a portion of the second rack 220 moves to bring the first end of the second rack 220 closer to the air deflection plate 100 and another portion moves to drive the air deflection plate 100 to turn. The air deflection 100 turns a smaller angle when the second rack 220 moves the same distance than when the second slot segment 612 is disposed parallel to the air deflection 100. This can improve the accuracy of controlling the turning of the air deflection plate 100.

Optionally, the second rotating shaft is in a closed state or a second open state of the air deflector 100 when in the first slot segment 611. In the second open state, the air deflection 100 extends outwardly while deflecting air upwardly and downwardly.

When the wind deflector 100 is in the closed state, the first rack 210 and the second rack 220 are in the initial positions. In the second open state of the air deflector 100, the stroke of the first rack 210 and the second rack 220 are the same, the air deflector 100 extends outward, and no overturning occurs with respect to the closed state. In this case, the protrusion at the junction of the first channel segment 611 and the second channel segment 612 may serve as a positioning function to place the air deflector 100 at the same angle as the closed state.

Alternatively, the second axis of rotation is in the first open position of the deflector 100 when in the second trough section 612. In an open state, the air deflector 100 directs air downward, and in a second open state, the air deflector 100 directs air downward.

The stroke of the second rack 220 is smaller than that of the first rack 210, and the wind deflector 100 turns in the first direction and guides the wind downward. When the air is guided downwards, a user of the air blown out by the air conditioner can feel more intuitively, so that the air outlet direction needs to be finely adjusted. When the second rotating shaft is in the second groove section 612, the control on the air outlet direction is accurate, so that the air conditioner can be used for air outlet at an accurate air outlet angle according to the operation intention of a user or automatically.

Optionally, the direction-adjusting track groove 610 further includes a third groove section 613, which is obliquely disposed, the first end is communicated with the second end of the second groove section 612, the distance between the first end and the air deflector 100 is smaller than the distance between the second end and the air deflector 100, and the connection position of the third groove section 613 and the second groove section 612 is protruded outwards.

The third groove section 613 is disposed obliquely, and the distance between the end close to the second groove section 612 and the air deflector 100 is smaller than the distance between the end far from the second groove section 612 and the air deflector 100. Thus, when the second rack 220 moves, the whole movement of the second rack 220 is used for driving the air deflector 100 to turn, and meanwhile, the distance between the first end of the second rack 220 and the air deflector 100 becomes longer, and under the combined action of two factors, the second rack 220 turns the air deflector 100. When the second rack 220 moves the same distance, the air guide plate 100 is turned over by a larger angle than in the case where the second groove section 612 is disposed parallel to the air guide plate 100, so that the range of controlling the turning of the air guide plate 100 can be increased.

Optionally, the second rotating shaft is in the third open state of the air deflector 100 when in the third slot section 613. In the third open state, the air guide plate 100 guides the air upward, and the air conditioner operates in the cooling mode.

When the air conditioner operates in the cooling mode, the turning angle of the air guide plate 100 determines the air supply distance of the air conditioner. Specifically, the closer the air guide plate 100 is disposed horizontally, the farther the air-conditioner is supplied. In the second rotation, in the third groove section 613, the third groove section 613 is obliquely arranged, and the second rack 220 can drive the air deflector 100 to turn over a larger angle, so that the air outlet range of the air conditioner is improved.

The protrusion at the joint of the second groove section 612 and the third groove section 613 plays a role in positioning the rotation of the second rotation shaft, and the second rotation shaft is not easy to enter the third groove section 613 when the second groove section 612 slides. Thus, the action of the air deflector 100 can be clearer, and good air guiding effect can be obtained in different air outlet modes.

Optionally, the second groove section 612 forms a first included angle with the first groove section 611, and the first included angle is greater than 90 degrees and less than 180 degrees; and/or the third groove section 613 forms a second angle with the second groove section 612, the second angle being greater than 90 degrees and less than 180 degrees.

The first included angle is greater than 90 degrees and less than 180 degrees, and the second rotating shaft can slide more smoothly when entering the second groove section 612 from the first groove section 611 or returning to the first groove section 611 from the second groove section 612. The bulge at the joint of the first groove section 611 and the second groove section 612 is naturally formed through the first included angle, so that the movement positioning of the air deflector 100 is facilitated.

The second included angle is greater than 90 degrees and less than 180 degrees, and can slide more smoothly when the second rotation shaft enters the third groove section 613 from the second groove section 612 or enters the second groove section 612 from the third groove section 613. The bulge at the joint of the first groove section 611 and the second groove section 612 is naturally formed through the first included angle, so that the movement positioning of the air deflector 100 is facilitated.

Optionally, the length of the first channel section 611 is less than the length of the second channel section 612.

The first groove section 611 is mainly used for keeping the air deflector 100 at the same angle in the closed state, and thus, the movement distance of the second rotation shaft in the first groove section 611 is short. The length of the first groove section 611 is shorter, and the length of the second groove section 612 is longer, so that the air deflector 100 can accurately control the rotation angle of the air deflector 100 in the second groove section 612.
