[0001] The present invention relates to the technical field of air conditioner structures, and particularly relates to a wind deflector pushing mechanism and an air conditioner thereof. Background Art

[0002] Based on the current wind deflector pushing mechanisms on the market, the pushing methods and directions thereof have relatively single variability, and all use a single rack to push in an arc or straight line direction, so the air guiding positions of the wind deflector are relatively single.

[0003] For example: A patent document with the application number CN201110234136.5 discloses an indoor unit of an air conditioner, which includes an air outlet, an air duct, and a wind deflector for guiding the air outlet direction of the air conditioner; a volute tongue is provided at the outer end of the air duct.

[0004] The wind deflector opening and closing mechanism includes a left pushing device and a right pushing device located at the left and right ends of the wind deflector and capable of driving the wind deflector to move in and out. One end of the left pushing device and the right pushing device is fixed on the air conditioner body, and the other end is connected to the back of the wind deflector.

[0005] The left pushing device includes a first driving motor, a left gear fixed on the output shaft of the first driving motor, a left rack connecting rod meshed with the left gear, and a left box body; the first driving motor is fixed outside the left box body, the left gear is located in the inner cavity of the left box body, and the output shaft of the first driving motor passes through the side wall of the left box body; the inner end of the left rack connecting rod reciprocates in the inner cavity of the left box body, and the outer end of the left rack connecting rod extends outside the left box body.

[0006] The right pushing device includes a second driving motor, a right gear fixed on the output shaft of the second driving motor, a right rack connecting rod meshed with the right gear, and a right box body; the second driving motor is fixed outside the right box body, the right gear is located in the inner cavity of the right box body, and the output shaft of the second driving motor passes through the side wall of the right box body; the inner end of the right rack connecting rod reciprocates in the inner cavity of the right box body, and the outer end of the right rack connecting rod extends outside the right box body and is connected to the right support end of the wind deflector.

[0007] The left rack connecting rod or the right rack connecting rod has a linear or curved linear structure.

[0008] The wind deflector in the above indoor unit of the air conditioner is pushed in an arc or straight line direction, and there is a problem that the air guiding positions of the wind deflector are relatively single. Summary of the Invention

[0009] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a wind deflector pushing mechanism to solve the problem in the prior art that the wind deflector is pushed in an arc or straight line direction, resulting in relatively single air guiding positions of the wind deflector.

[0010] To achieve the above object, the present invention adopts the following technical solution: An air deflector pushing mechanism, comprising:

[0011] A bracket, which is used to be fixedly connected to the side of the air conditioner middle frame;

[0012] An orbital plate, which is slidably connected to the bracket along the Y-axis direction;

[0013] A defined locus plate, which is slidably connected to the orbital plate along the X-axis direction and has a moving internal gear ring formed at one end, and the other end is connected to the air deflector through a rotary driving mechanism to drive the air deflector to move;

[0014] A pushing driving mechanism, which is fixedly connected to the bracket and meshes with the moving internal gear ring.

[0015] Working principle: When the pushing driving mechanism operates, by meshing with the moving internal gear ring, the defined locus plate slides along the X-axis direction on the orbital plate, and at the same time, the orbital plate slides along the Y-axis direction on the bracket, so that the defined locus plate moves in both the X-axis direction and the Y-axis direction. Then, the defined locus plate drives the air deflector to move in both the X-axis direction and the Y-axis direction through the rotary driving mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This air deflector pushing mechanism is mainly composed of a bracket, an orbital plate, a defined locus plate and a pushing driving mechanism, so that the air deflector moves in both the X-axis direction and the Y-axis direction, thereby enriching the air guiding positions of the air deflector and realizing the position requirements of the air deflector in different modes.

[0018] To achieve the above object, the present invention also adopts the following technical solution: An air conditioner, comprising the above air deflector pushing mechanism; so that the air conditioner has the beneficial effects of the above air deflector pushing mechanism.

Detailed implementation manners

[0028] The present invention will be further described in detail below through specific implementation manners:

[0029] As Figure 1 shown, an embodiment of the present invention provides an air conditioner, including an air deflector pushing mechanism 1, where the air deflector pushing mechanism 1 is disposed on the side of the middle frame of the air conditioner and connected to the air deflector, and is used to adjust the position requirements of the air deflector in different modes; for example, when the air conditioner is in the cooling and heating modes, the position requirements for the air deflector are very different.

[0030] Here, the position of the air deflector is reasonably adjusted through the air deflector pushing mechanism 1 to meet the position requirements in different modes.

[0031] As Figure 2 shown, according to another embodiment of the present invention, the air conditioner, wherein the air deflector pushing mechanism 1 includes a bracket 11, a track plate 12, a defined track plate 13, and a pushing drive mechanism 14;

[0032] Among them, the bracket 11 is used to be fixedly connected to the side of the middle frame of the air conditioner;

[0033] The track plate 12 is slidably connected to the bracket 11 along the Y-axis direction;

[0034] The defined track plate 13 is slidably connected to the track plate 12 in the X-axis direction, and a moving internal gear ring 15 is formed at one end thereof, and the other end is connected to the air deflector through a rotary drive mechanism to drive the air deflector to move;

[0035] The pushing drive mechanism 14 is fixedly connected to the bracket 11 and meshes with the moving internal gear ring 15.

[0036] Such as Figure 3 , Figure 4 and Figure 5 , specifically: when the pushing drive mechanism 14 operates, by meshing with the moving internal gear ring 15, the defined track plate 13 slides on the track plate 12 in the X-axis direction, and at the same time, the track plate 12 slides on the bracket 11 in the Y-axis direction, so that the defined track plate 13 moves in both the X-axis direction and the Y-axis direction. Then, the defined track plate 13 drives the air deflector to move in both the X-axis direction and the Y-axis direction through the rotary drive mechanism, thereby enriching the air guiding positions of the air deflector and realizing the position requirements of the air deflector in different modes.

[0037] Such as Figure 6 shown, according to another embodiment of the present invention, the air conditioner, wherein the defined track plate 13 includes an internal gear ring mounting portion 131 and a drive mounting portion 132;

[0038] Wherein, the bottom of the internal gear ring mounting portion 131 is slidably connected to the track plate 12 in the X-axis direction, and the moving internal gear ring 15 is arranged at the top of the internal gear ring mounting portion 131;

[0039] The drive mounting portion 132 is fixedly connected to one end of the internal gear ring mounting portion 131, and a wire pressing cover 133 is buckled thereon, and an installation cavity 134 for installing the rotary drive mechanism is formed between the wire pressing cover 133 and the drive mounting portion 132.

[0040] Herein: The moving internal gear ring 15 is installed through the internal gear ring mounting part 131 and is connected to the track plate 12. When the pushing drive mechanism 14 operates, the internal gear ring mounting part 131 slides along the X-axis direction on the track plate 12 through the cooperation of the pushing drive mechanism 14 and the moving internal gear ring 15. At the same time, the track plate 12 slides along the Y-axis direction on the bracket 11, so that the internal gear ring mounting part 131 slides along the X-axis direction and the Y-axis direction, driving the mounting part 132 to run synchronously with the internal gear ring mounting part 131. Furthermore, the air deflector is driven to move through the rotation drive mechanism to change the position of the air deflector. And the wire pressing cover 133 cooperates with the driving mounting part 132 to form an installation cavity 134, and then the rotation drive mechanism is reasonably installed and arranged, making the structure more compact. Among them, the rotation drive mechanism adopted specifically includes a motor installed in the installation cavity 134. A small gear is fixedly connected to the output shaft of the motor. The small gear meshes with a large gear rotatably arranged in the installation cavity 134. The large gear is connected to the air deflector through a rotating shaft, and the rotating shaft freely passes through the installation cavity 134. When the motor operates, the torque is changed through the cooperation of the small gear and the large gear, so that the air deflector rotates stably through the rotating shaft, to adjust the opening and closing of the air deflector to the air outlet of the air conditioner and the air guiding angle.

[0041] Furthermore, the internal gear ring mounting part 131 and the driving mounting part 132 are connected through a connecting part 135, and a plurality of reinforcing ribs 136 are formed on the connecting part 135. One ends of the plurality of reinforcing ribs 136 all extend to be fixedly connected to the moving internal gear ring 15.

[0042] Specifically: The internal gear ring mounting part 131, the driving mounting part 132 and the connecting part 135 are integrally formed. The number of the reinforcing ribs 136 in this embodiment is two. The reinforcing ribs 136 are beneficial to improving the structural strength of the defined track plate 13 and the moving internal gear ring 15, and improving the stability of the defined track plate 13 and the moving internal gear ring 15 during the movement process.

[0043] Such as Figure 2 、 Figure 7 and Figure 8 As shown, according to another embodiment of the present invention, a first sliding groove 16 arranged along the Y-axis direction is formed on the bracket 11, and a first connecting protrusion 17 is formed on the track plate 12. The first connecting protrusion 17 is slidably connected in the first sliding groove 16 along the Y-axis direction.

[0044] The track slab 12 is stably slidably connected to the bracket 11 along the Y-axis direction through the cooperation of the first chute 16 and the first connecting protrusion 17. At the same time, a second chute 18 arranged along the X-axis direction is formed on the track slab 12. It is defined that one end of the track plate 13 connected to the moving internal gear ring 15 is slidably arranged in the second chute 18 along the X-axis direction, that is, the internal gear ring mounting portion 131 is slidably arranged in the second chute 18 along the X-axis direction. The internal gear ring mounting portion 131 is stably slidably connected to the track slab 12 along the X-axis direction through the cooperation of the internal gear ring mounting portion 131 and the second chute 18.

[0045] By using the cooperation of the first chute 16 and the first connecting protrusion 17, the cooperation of the internal gear ring mounting portion 131 and the second chute 18, and the cooperation of the moving internal gear ring 15 and the pushing drive mechanism 14, the multi-directional and complex position pushing and positioning of the air deflector are realized, and the position requirements of the air deflector in different modes are realized.

[0046] The air deflector pushing mechanism 1 of the present invention utilizes a bidirectional chute to effectively realize various defined motion trajectories, and utilizes the limit and guidance of the moving internal gear ring 15 to effectively ensure the accuracy and stability of the pushing position.

[0047] Moreover, the moving internal gear ring 15 is designed in a triangular shape, and its corners are all rounded; the shape of the moving internal gear ring 15 is not limited to this, and can be adjusted accordingly according to the actual situation; further effectively solves the singularity of the pushing position of the air deflector, and realizes various types of pushing positions by switching the defined motion trajectory, with strong applicability and replaceability.

[0048] At the same time, by using the chute, the assembly efficiency is greatly improved. The assembly does not require the use of small guide wheels or positioning wheels, and the assembly is simple and convenient, improving the assembly processability of the overall mechanism.

[0049] Such as Figure 2 and Figure 7 As shown, according to another embodiment of the present invention, in the air conditioner, the bracket 11 includes a frame body mounting portion 111 and a connecting portion 112;

[0050] Among them, the frame body mounting portion 111 is in a "U" shape, the first chute 16 is opened on the inner side wall of one end of the frame body mounting portion 111, and the pushing drive mechanism 14 is fixedly connected to the outer side wall of the other end of the frame body mounting portion 111;

[0051] The connecting portion 112 is located outside the frame body mounting portion 111 and is fixedly connected to the outer bottom wall of the frame body mounting portion 111. The connecting portion 112 is used for fixedly connecting to the side of the air conditioner middle frame.

[0052] Specifically, the connecting part 112 can be fixedly connected to the side of the air conditioner middle frame through buckles and screws, and the frame installation part 111 is designed in a "U" shape, which is convenient for opening the first sliding groove 16 on the frame installation part 111 to enable the stable sliding of the track plate 12 inside the frame installation part 111, improving the assembly stability between the track plate 12 and the bracket 11. At the same time, it is also convenient to reasonably install the pushing drive mechanism 14 to stably cooperate with the moving internal gear ring 15. Among them, the distance between one end of the first sliding groove 16 provided on the frame installation part 111 and the bottom of the frame installation part 111 is greater than the distance between the other end of the frame installation part 111 and the bottom of the frame installation part 111, so that a staggered notch is formed at the opening of the frame installation part 111, facilitating the quick assembly of the first connecting protrusion 17 at the bottom of the track plate 12 into the first sliding groove 16.

[0053] As Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, according to another embodiment of the present invention, in the air conditioner, the pushing drive mechanism 14 includes a driver 141 and a circular gear 142;

[0054] Among them, the driver 141 is fixedly arranged on the bracket 11;

[0055] The circular gear 142 is driven to rotate by the driver 141 and also meshes with the moving internal gear ring 15.

[0056] In this embodiment: The driver 141 can also be a motor. When the motor drives the circular gear 142 to rotate through the meshing of the circular gear 142 and the moving internal gear ring 15, it drives the defined trajectory plate 13 to slide along the X-axis direction on the track plate 12. At the same time, the track plate 12 slides along the Y-axis direction on the bracket 11, so that the defined trajectory plate 13 moves in both the X-axis direction and the Y-axis direction. Then, the defined trajectory plate 13 drives the air deflector to move in both the X-axis direction and the Y-axis direction through the rotation drive mechanism, thus enriching the air deflector's air guiding position and realizing the position requirements of the air deflector in different modes.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
