It should be noted that the air deflector body 50 may not contact with the first limiting block 24 or the second limiting block 25, and the start and stop of the movement of the air deflector body 50 are directly controlled by the motor. The first stopper 24 and the second stopper 25 are mainly used for controlling the rotation range of the second link 30 on the first link 20.

Referring to fig. 3 and 8, an embodiment of the present disclosure provides an air guiding plate driving assembly, which includes an air guiding plate body 50, a driving structure, a matching structure, and the above connecting rod structure.

As shown in fig. 4, optionally, the fitting structure includes: and a second link 30 mounted on the first link 20, wherein a guide post 33 is mounted on a surface of the second link 30 adjacent to the first link 20, the guide post 33 is engaged with the second guide rail 23, and the second link 30 can rotate on the first link 20 around the guide post 33.

It will be appreciated that the second link 30 is slidably engaged with the first link 20 via the guide post 33 such that the second link 30 is movable along the second guide rail 23. Preferably, the guide post 33 is a cylinder, and the second link 30 is rotatable about the guide post 33. The second link 30 is rotatable on the second guide rail 23 about the guide post 33 with respect to the first link 20. When the second link 30 rotates, the second link 30 pushes the air deflector body 50 to rotate around the first hinge point 511 of the connection between the first link 20 and the air deflector body 50. The rotation of the second link 30 and the movement along the second guide rail 23 may be performed simultaneously, or may be performed only along the second guide rail 23.

As an example, the second link 30 has a key-shaped structure, an upper portion having a ring-shaped structure, a middle portion having a through slot 31, a lower portion having a rod 32, and a guide post 33 disposed on a surface of the rod 32 facing the first link 20. The position of the through slot 31 is matched with the position of the first guide rail 22, so that the driving element 40 can drive the first connecting rod 20 and the second connecting rod 30 conveniently, and the interference of the movement of the first connecting rod 20 and the second connecting rod 30 can be avoided, and the second connecting rod 30 can rotate or move on the second guide rail 23 through the guide column 33.

As an example, the length of the second guide rail 23 is greater than or equal to the moving distance of the guide pillar 33 on the second link 30 to meet the requirement of the yaw angle.

As another example, the through groove 31 of the second link 30 is a rectangular through groove 31 to control the movement locus of the second link 30.

As shown in fig. 7, optionally, the air deflector body 50 is provided with a mounting seat 51, the mounting seat 51 is provided with a first hinge point 511 and a second hinge point 512, the first hinge point 511 is connected with the first connecting rod 20, and the second hinge point 512 is connected with the second connecting rod 30.

As shown in fig. 6, optionally, the air deflector drive assembly further includes: the chassis 10 is provided with a second guide structure 11 cooperating with the first guide structure 21.

It can be understood that, the first link 20 is used as a main component for pushing the air deflector body 50 out of the body, and in order to ensure that the moving track of the air deflector does not deviate, a guide structure is required to be arranged for guiding, the second guide structure 11 matched with the first link 20 is arranged on the bottom frame 10 in the embodiment of the disclosure, so that the integral installation of the air deflector driving assembly can be facilitated, the air conditioner does not need to be greatly changed during use, the production cost of the air conditioner is reduced, and the occupied space of the indoor unit of the air conditioner is saved.

Alternatively, the extension direction of the first guide rail 22 is arranged at an angle to the direction directed by the first guide structure 21.

It can be understood that when the driving element 40 rotates, the protruding pillar 422 will move along the first guiding rail 22, and since the driving element 40 moves in a circular shape, the force applied by the protruding pillar 422 to the first guiding rail 22 can be divided into two parts, one part of the force pushes the protruding pillar 422 to move on the first guiding rail 22, and the other part of the force pushes the first connecting rod 20 to move along the direction guided by the first guiding structure 21, so that the first connecting rod 20 pushes the air deflector body 50 out of the machine body.

Preferably, the extending direction of the first guide rail 22 is perpendicular to the guiding direction of the first guide structure 21 and the second guide structure 11. The first guide rail 22 is disposed perpendicular to the second guide rail 23. This can prevent the movement of the first and

second links

20 and 30 from interfering with or canceling out each other.

As an example, the first guiding structure 21 is a dual guiding rail disposed in parallel, and the second guiding structure 11 is a sliding block disposed on each guiding rail of the dual guiding rail, so that the first link 20 has sufficient motion stability. The second guide structure 11 may be provided as two parallel guide rails, and the first guide structure 21 may be a slider provided on each of the two guide rails.

As shown in fig. 5, optionally, the driving structure includes: the driving element 40 is provided with a flange 421 and a convex column 422, the flange 421 is matched with the through groove 31 in position, and the convex column 422 is matched with the first guide rail 22 in position; the protruding column 422 is used for driving the first connecting rod 20 to push out the air deflector body 50, and the flange 421 is used for driving the second connecting rod 30 to push the air deflector body 50 to rotate.

It will be appreciated that the first link 20 and the second link 30 cooperate to provide a large angular rotation of the air deflection plate. The driving element 40 is provided with a convex column 422, the air deflector driving assembly pushes the first guide rail 22 through the convex column 422 to drive the first connecting rod 20 to push out the air deflector body 50, because the second connecting rod 30 is connected with the air deflector body 50, the second connecting rod 30 also stretches along with the first connecting rod 20, and the air deflector driving assembly pushes the through groove 31 through the flange 421 of the driving element 40 to drive the second connecting rod 30 to rotate on the first connecting rod 20 to push the air deflector body 50 to rotate.

As an example, the driving element 40 includes a shaft coupling seat 41 and a connecting rod 42, one end of the shaft coupling seat 41 is connected to the shaft coupling seat 41, the other end is provided with a flange 421, and a convex pillar 422 is disposed on a surface of the connecting rod 42 facing the first connecting rod 20.

It is understood that the driving element 40 of the embodiment of the present disclosure is a key-like structure, the central portion of the coupling seat 41 is provided with a hole for connecting with the driving shaft of the motor, the connecting rod 42 is connected with the side of the coupling seat 41, and the flange 421 is provided at the edge of the driving element 40 and is a protruding structure for pushing the through slot 31 to move the second link 30 on the first link 20. When the driving element 40 rotates, the connecting rod 42 and the convex column 422 rotate synchronously, the flange 421 is located at the end of the connecting rod 42, is located in the through groove 31 of the second connecting rod 30, can trigger the second connecting rod 30 to move by contacting with the inner side wall of the through groove 31, and the convex column 422 is located on one surface, facing the first connecting rod 20, of the connecting rod 42, so that the convex column 422 can be matched with the first guide rail 22 to enable the convex column 422 to drive the first connecting rod 20 to move.

Optionally, the protruding column 422 passes through the through slot 31 to be slidably connected with the first guiding rail 22. In this way, it is possible to facilitate the driving of the first link 20 and the second link 30 by the driving member 40, and to avoid the movement of the first link 20 and the second link 30 from interfering with each other.

Optionally, the distance between stud 422 and the rotational axis of drive element 40 is greater than or equal to a set distance.

It can be understood that the convex pillar 422 is one of the main components for driving the air deflector body 50 to leave the machine body, and the distance between the convex pillar 422 and the rotation axis determines the moving distance of the convex pillar 422 on the first guide rail 22, which will also affect the moving distance of the first connecting rod 20 on the underframe 10 and the distance that the air deflector body 50 is pushed away from the machine body. Therefore, the distance between the protruding pillar 422 and the rotation axis of the driving element 40 should be greater than or equal to the predetermined distance, so that the first link 20 can push the air deflector body 50 out by a sufficient length. The set distance is a length that the first link 20 can push out the air deflector body 50 without affecting the rotation of the air deflector body 50. The rotation shaft may be a virtual shaft or may be a drive shaft of a motor that drives the drive element 40 to rotate.

The operation of the disclosed embodiment will be described with reference to fig. 1-8.

The chassis 10 is provided with double sliders, the surface of the first connecting rod 20 facing the chassis 10 is provided with double guide rails matched with the double sliders, and the surface of the first connecting rod 20 far away from the chassis 10 is provided with a first guide rail 22, a second guide rail 23, a first limiting block 24 and a second limiting block 25. The extending direction of the first guide rail 22 is perpendicular to the guiding direction of the dual guide rail, the extending direction of the second guide rail 23 is the same as the guiding direction of the dual guide rail, the first limiting block 24 is located on one side of the second guide rail 23, and the second limiting block 25 is located on the other side of the second guide rail 23. Wherein the first guide rail 22 is adapted to cooperate with the stud 422 of the driving element 40 and the second guide rail 23 is adapted to cooperate with the guide post 33 of the second link 30.

The second link 30 is a key-shaped structure, the upper portion is a ring-shaped structure, the middle portion is provided with a rectangular through groove 31, the lower portion is a rod body 32, and a guide post 33 is arranged on one side of the rod body 32 facing the first link 20. The position of the through slot 31 is matched with the position of the first guide rail 22, so that the driving element 40 drives the first connecting rod 20 and the second connecting rod 30, and the second connecting rod 30 can rotate or slide on the second guide rail 23 through the guide post 33. The flange 421 of the driving element 40 is located in the through slot 31, and the flange 421 pushes the through slot 31 to displace the second link 30, so as to push the air deflector body 50 to rotate.

In practice, when the air deflector is closed, the connecting rod 42 of the driving element 40 is located on the straight line of the second guide rail 23 and points away from the second guide rail 23; when the air deflector body 50 needs to be opened downwards, the driving element 40 is rotated in the first rotating direction, the convex column 422 is driven to move towards the first end of the first guide rail 22, in the moving process, the convex column 422 generates a component force to the first guide rail 22 to drive the first connecting rod 20 to extend outwards and push the air deflector body 50 out of the machine body, the air deflector body 50 is hinged with the second connecting rod 30, so the air deflector body 50 moves and simultaneously drives the second connecting rod 30 to extend outwards synchronously, in the process, the first connecting rod 20 and the second connecting rod 30 are relatively static, when the driving element 40 reaches the first end of the first guide rail 22, the flange 421 starts to contact with the lower edge of the rectangular through groove 31 and gradually supports against the lower edge of the rectangular through groove 31 to push the second connecting rod 30 to move, because the first connecting rod 20 is limited by the double guide rails and can only do telescopic movement, the second connecting rod 30 and the first connecting rod 20 are only in a matching relationship with the second guide rail 23 at the guide column 33, the second link 30 will be deflected by the thrust of the flange 421 and push the air deflector body 50 to rotate. When the air deflector body 50 contacts with the fourth inclined plane of the second limiting block 25, the air deflector body 50 reaches the maximum opening angle, at this time, because the air deflector is pressed, the load of the motor is suddenly increased, at this time, the motor stops moving, and the air deflector is located at the maximum opening angle to supply air. If the second connecting rod 30 contacts the first inclined surface of the first stopper 24 before the air deflector body 50 contacts the fourth inclined surface of the second stopper 25, the driving element 40 will push the second connecting rod 30 to move down along the second guide rail 23 while keeping contact with the first inclined surface, so that the opening angle of the air deflector body 50 is larger, and the motor stops moving until the air deflector body 50 abuts against the fourth inclined surface of the first stopper 24.

When carrying out the opening direction and switching, supposing to realize that the motor anticlockwise drives drive element and rotates when aviation baffle body 50 upwards opening is sent wind, when will switch to aviation baffle body 50 downwards opening and send wind the time motor only need change the rotation direction, clockwise rotation, and the aviation baffle needs to reach the closure earlier this moment, and the motor continues to drive element clockwise rotation and can switch to the opening angle that heats. The switching of the opening direction of the air deflector body 50 is realized only by controlling the forward and reverse rotation of the motor.

The stop motion of the air deflector can be realized from two aspects, on one hand, the motor is used for controlling the operation angle of the air deflector body 50, when the motor stops, no force is used for driving the air deflector body 50 to move, the air deflector body 50 stops moving, on the other hand, when the air deflector body 50 abuts against the first limiting block 24 or the second limiting block 25, the air deflector body 50 cannot continue to rotate, meanwhile, the motion step number of the motor is calculated according to the rotation angle of the motor transmission shaft, and when the maximum rotation angle is reached, the motor stops rotating.

By adopting the air deflector driving assembly provided by the embodiment of the disclosure, the driving element 40 can drive the first connecting rod 20 and the second connecting rod 30, and when the air deflector driving assembly is implemented, a group of driving structures are adopted to drive the driving element 40 to move, so that the pushing-out and rotating actions of the air deflector can be realized, and the problems of high cost and low movement reliability of the air deflector caused by a large number of driving structures are solved.
