Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0044] At present, the air outlet of the air conditioner is equipped with a swing blade mechanism, which includes a swing blade assembly and a driving device. The driving device includes a motor, which is used to drive the swing blades of the swing blade assembly to swing, so as to realize the switching of multiple air supply modes of the air conditioner.

[0045] The motor is set with a zero point, which is the reference point for the motor's operation. Once the zero point is lost, the air conditioner will not be able to accurately switch between multiple air supply modes.

[0046] To this end, the utility model proposes a swing blade mechanism, which aims to enable the motor to calibrate the zero point, so that the air conditioner can accurately switch between multiple air supply modes.

[0047] Reference Figures 1 to 10 In one embodiment of the present invention, the swing blade mechanism 200 can be, but is not limited to, installed at the air outlet 110 of the air conditioner 100. Without loss of generality, for ease of description, this article takes the swing blade mechanism 200 installed at the air outlet 110 of the air conditioner 100 as an example for introduction.

[0048] The swing blade mechanism 200 includes a swing blade assembly 210 and a driving device 300 . The driving device 300 includes a transmission mechanism 320 and a motor 310 . The transmission mechanism 320 includes a mounting shell 330 , a rotating member 340 and a ratchet 400 .

[0049] The motor 310 drives the swing blade assembly 210 via the rotating member 340 , thereby realizing the swing blades 240 of the swing blade assembly 210 to swing, and then the air conditioner 100 can realize a variety of air supply modes through the swing of the swing blades 240 .

[0050] In addition, the rotating member 340 can be rotatably installed on the mounting shell 330. One of the rotating member 340 and the mounting shell 330 is provided with a guide rail 350, and the other is rotatably installed with a pawl 400. The pawl 400 can also be slidably connected to the guide rail 350. The guide rail 350 includes a loop 351 arranged around the rotation axis of the rotating member 340, and a positioning section 354 with one end connected to the loop 351. The other end of the positioning section 354 is provided with a positioning structure 380.

[0051] The rotating member 340 rotates along the first circumferential direction, which can drive the pawl 400 to rotate in the loop 351. The rotating member 340 rotates in the direction opposite to the first circumferential direction, which can drive the pawl 400 from the loop 351 into the positioning section 354, so that the pawl 400 can stop at the positioning structure 380. The motor 310 calibrates the zero point by stopping the pawl 400 at the positioning structure 380.

[0052] In this way, the air conditioner 100 can drive the rotating member 340 through the motor 310 when it is turned on, so that the rotating member 340 rotates in the direction opposite to the first circumferential direction, so that the ratchet 400 enters the positioning section 354 from the loop 351, and when the ratchet 400 stops at the positioning structure 380, the motor 310 realizes the zero point calibration. In this way, the air conditioner 100 can accurately switch between multiple air supply modes.

[0053] Optionally, in one embodiment, the loop 351 includes a first guide section 352 and a second guide section 353, the first guide section 352 and the second guide section 353 extend in different directions relative to the port of the positioning section 354 connecting the loop 351, the first guide section 352 is smoothly connected to the positioning section 354, and the second guide section 353 is arranged in parallel with the positioning section 354. It can be understood that when the rotating member 340 rotates in the direction opposite to the first circumferential direction, the pawl 400 can enter the positioning section 354 from the first guide section 352. Since the first guide section 352 and the positioning section 354 are smoothly connected, the process of the pawl 400 entering the positioning section 354 from the first guide section 352 is relatively smooth. In addition, when the rotating member 340 moves in the first circumferential direction, the pawl 400 can enter the first guide section 352 from the second guide section 353, and the second guide section 353 and the positioning section 354 are arranged in parallel to reduce the difficulty of processing the guide rail 350.

[0054] There are many relative positions of the second guide section 353 and the positioning section 354. Optionally, in one embodiment, the distance from the second guide section 353 to the rotation axis of the rotating member 340 is greater than the distance from the positioning section 354 to the rotation axis of the rotating member 340. However, the present design is not limited thereto. In other embodiments, the distance from the second guide section 353 to the rotation axis of the rotating member 340 is less than the distance from the positioning section 354 to the rotation axis of the rotating member 340.

[0055] Optionally, in one embodiment, the second guide section 353 is connected to the first guide section 352 through the arc-shaped guide groove 355. In this way, the process of the pawl 400 entering the first guide section 352 from the second guide section 353 is smoother. However, the present design is not limited thereto, and in other embodiments, the first guide section 352 and the second guide section 353 are smoothly connected.

[0056] Optionally, in one embodiment, the rotating member 340 is provided with an incomplete tooth portion 360, and the transmission mechanism 320 also includes a complete gear 500 rotatably provided on the mounting shell 330, and the motor 310 drives the complete gear 500 through the rotating member 340, and the rotating member 340 and the complete gear 500 are respectively driven and connected to a pendulum blade assembly 210, so that the pendulum blades 240 of the two pendulum blade assemblies 210 have two working modes of swinging in the same direction and swinging in the opposite direction, and the pawl 400 can switch the working mode by moving one circle along the first circumferential loop 351.

[0057] For ease of description, the two swing blade assemblies 210 are respectively configured as a first swing blade assembly 220 and a second swing blade assembly 230, the connecting rod and the swing blade 240 of the first swing blade assembly 220 are respectively configured as a first connecting rod 270 and a first swing blade 250, and the connecting rod and the swing blade 240 of the second swing blade assembly 230 are respectively configured as a second connecting rod 280 and a second swing blade 260. The first connecting rod 270 and the second connecting rod 280 are sequentially distributed along the first direction, so that the first swing blade 250 and the second swing blade 260 are sequentially distributed along the first direction, and further the first swing blade 250 and the second swing blade 260 can control the wind direction of the outlet airflow of the air outlet 110 in different areas in the first direction.

[0058] When the swing blade mechanism 200 is installed on the air outlet 110, the first direction can be set in parallel with the length direction of the air outlet 110. For example, when the length direction of the air outlet 110 is the left-right direction of the air conditioner 100, the first direction can be set to the right direction. When the length direction of the air outlet 110 is the up-down direction of the air conditioner 100, the first direction can be set to the up direction. It should be noted that the left direction and the right direction of the air conditioner 100 refer to that when the user faces the front side of the air conditioner 100, the left direction of the user is the left direction of the air conditioner 100, and the right direction of the user is the right direction of the air conditioner 100. It can be understood that there are many relative postures between the swing blade mechanism 200 and the air outlet 110. For other situations, similar deductions can be made according to the following text, and no further elaboration will be made here. This article introduces the first direction as the right direction.

[0059] Since the swing blades 240 of the two swing blade assemblies 210 have two working modes of swinging in the same direction and swinging in the opposite direction, the fixed air supply mode of the air conditioner 100 includes a concentrated air supply mode, a dispersed air supply mode, a first side air supply mode, and a second side air supply mode. It should be noted that the fixed air supply mode refers to an air supply mode for guiding the outlet air flow when the first swing blade 250 and the second swing blade 260 stop swinging.

[0060] Specifically, in the centralized air supply mode, the first swing blade 250 is tilted in a first direction in the air outlet direction of the air outlet 110, so that the air outlet airflow guided by the first swing blade 250 is tilted in the first direction, and the second swing blade 260 is tilted in a second direction opposite to the first direction in the air outlet direction of the air outlet 110, so that the air outlet airflow guided by the second swing blade 260 is tilted in the second direction. In this way, in the air outlet direction of the air outlet 110, the air outlet airflows respectively guided by the first swing blade 250 and the second swing blade 260 will gradually approach each other, so that the two air outlet airflows have a tendency to converge;

[0061] In the dispersed air supply mode, the first swing blade 250 is inclined in the second direction in the air outlet direction of the air outlet 110, and the second swing blade 260 is inclined in the first direction in the air outlet direction of the air outlet 110. In this way, in the air outlet direction of the air outlet 110, the airflows guided by the first swing blade 250 and the second swing blade 260 will gradually move away from each other, so that the two airflows have a dispersed trend.

[0062] In the first side air supply mode, the first swing blade 250 and the second swing blade 260 are both inclined along the first direction in the air outlet direction of the air outlet 110, so that the airflows guided by the first swing blade 250 and the second swing blade 260 are respectively inclined along the first direction.

[0063] In the second side air supply mode, the first swing blade 250 and the second swing blade 260 are both inclined in the second direction in the air outlet direction of the air outlet 110, so that the airflows guided by the first swing blade 250 and the second swing blade 260 are respectively inclined in the second direction.

[0064] It is understood that the air conditioner 100 also includes a swing air supply mode, which refers to a supply mode in which the first swing blade 250 and / or the second swing blade 260 swing back and forth to guide the air flow. In this way, the swing blade mechanism 200 enriches the air supply mode of the air conditioner 100.

[0065] In addition, the present solution can drive two swing blade assemblies 210 through a motor 310, so that the swing blades 240 of the two swing blade assemblies 210 have two working modes of same-direction swinging and reverse swinging, which is beneficial to simplify the structure of the swing blade mechanism 200 and reduce the manufacturing cost of the swing blade mechanism 200.

[0066] It can be understood that the rotating member 340 and the complete gear 500 constitute an incomplete gear 500 mechanism, which allows the pawl 400 to switch the above-mentioned working mode by moving one circle along the first circumferential loop 351. For example, the pendulums 240 of the two pendulum leaf assemblies 210 are in a working mode of swinging in the same direction, and the rotating member 340 rotates one circle, which can make the pendulums 240 of the two pendulum leaf assemblies 210 in a working mode of swinging in the opposite direction. At this time, the pawl 400 moves one circle along the first circumferential loop 351. For another example, the pendulums 240 of the two pendulum leaf assemblies 210 are in a working mode of swinging in the opposite direction, and the rotating member 340 rotates one circle, which can make the pendulums 240 of the two pendulum leaf assemblies 210 in a working mode of swinging in the same direction. At this time, the pawl 400 moves one circle along the first circumferential loop 351. It can be understood that in the process of switching the working mode, the pawl 400 will not interfere with the guide rail 350.

[0067] Optionally, in one embodiment, when the complete gear 500 and the incomplete tooth portion 360 are meshed, the pawl 400 moves on the first track of the guide rail 350, and the first track includes at least a portion of the positioning section 354 and at least a portion of the first guide section 352. It can be understood that when the air conditioner 100 enters the fixed air supply mode and the swing air supply mode, the complete gear 500 and the incomplete gear 500 are in a meshing state. In this way, when the air conditioner 100 enters the fixed air supply mode and the swing air supply mode, the present solution makes full use of the positioning section 354. When the air conditioner is turned on and the motor 310 completes the zero position calibration, the pawl 400 is located in the positioning section 354, which makes the distance for the pawl 400 to enter the first track shorter, which is beneficial for the air conditioner 100 to quickly enter the fixed air supply mode or the swing air supply mode. The schematic diagram of the first track is shown in FIG. Figure 8 As shown in segment ABC.

[0068] Optionally, in one embodiment, the midpoint of the first track is provided with an initial position 357, and when the pawl 400 abuts against the positioning structure 380, the pawl 400 can be rotated relative to the guide rail 350 by a preset angle to reset to the initial position 357. In this way, when the air conditioner 100 is turned on, the pawl 400 can move to the initial position 357. Without loss of generality, if the rotating member 340 moves along the first direction to the first track at this time, the air conditioner 100 will enter the first side air supply mode, and if the rotating member 340 moves along the second direction to the first track, the air conditioner 100 will enter the second side air supply mode. In this way, the difficulty of designing the air supply mode of the air conditioner 100 can be reduced.

[0069] Since the rotating member 340 is provided with an incomplete tooth portion 360, when the incomplete tooth portion 360 is used to mesh with the complete gear 500 for transmission, if the incomplete tooth portion 360 is separated from the complete gear 500 and the complete gear 500 is not restricted, the complete gear 500 may rotate under the action of inertia or external force. Thereafter, when the incomplete tooth portion 360 is meshed with the complete gear 500 again, the relationship between the incomplete gear 500 and the complete gear 500 will be disordered, and the swing blade 240 cannot move according to the predetermined trajectory, thereby causing the air supply mode of the air conditioner 100 to be disordered. To this end, optionally, in one embodiment, the rotating member 340 is provided with a first locking arc portion 370 disposed around the rotation axis of the rotating member 340, and the complete gear 500 is provided with a second locking arc portion 510 disposed around the rotation axis of the rotating member 340. When the incomplete tooth portion 360 is meshed with the complete gear 500, the first locking arc portion 370 is separated from the second locking arc portion 510, and when the incomplete tooth portion 360 is separated from the complete gear 500, the first locking arc portion 370 is matched with the second locking arc portion 510. In this way, when the incomplete tooth portion 360 is separated from the complete gear 500, under the cooperation of the first locking arc portion 370 and the second locking arc portion 510, the complete gear 500 will not rotate, so that the complete gear 500 waits for the next meshing with the incomplete tooth portion 360, so that the swing blade 240 can move according to the predetermined trajectory, and thus the air supply mode of the air conditioner 100 will not be disordered.

[0070] There are many structural forms of the pawl 400. Optionally, in one embodiment, one end of the pawl 400 is rotatably connected to the mounting shell 330, and the other end is provided with a limiting protrusion 410 that cooperates with the guide rail 350. It can be understood that the rotating member 340 is provided with the guide rail 350. However, the present design is not limited thereto. In other embodiments, the pawl 400 can also be in other structural forms, which are not limited here.

[0071] Optionally, in one embodiment, the mounting shell 330 is configured as a gear box, the mounting shell 330 includes a first shell 331 and a second shell 332 that defines a receiving chamber with the first shell 331, the full gear 500 and the rotating member 340 are received in the gear box, and the motor 310 is disposed in the gear box. The gear box can protect the full gear 500 and the rotating member 340 to prevent foreign matter from appearing at the meshing point of the full gear 500 and the rotating member 340, thereby ensuring smooth operation of the full gear 500 and the rotating member 340. In addition, the ratchet 400 is rotatably disposed in the second shell 332.

[0072] Optionally, in one embodiment, the positioning structure 380 is a ratchet groove, and the pawl 400 can engage and stop in the ratchet groove. In this way, when the pawl 400 stops at the positioning structure 380, the engagement between the pawl 400 and the ratchet is more stable. However, the present design is not limited to this. In other embodiments, the positioning structure 380 can also be in other structural forms, as long as it can be stopped by the pawl 400.

[0073] Optionally, in one embodiment, the rotating member 340 is coaxially connected to a ratchet 390, and a ratchet groove is formed on the ratchet 390. The ratchet 390 is coaxially arranged with the rotating member 340, so that the weight of the rotating member 340 is more even, so that the rotating member 340 rotates more smoothly. However, the present design is not limited to this, and in other embodiments, the ratchet groove can also be formed in other parts of the rotating member 340, which is not limited here.

[0074] To guide as much air flow as possible, optionally, the first direction is parallel to the length direction of the air outlet 110. However, the present design is not limited thereto, and in other embodiments, the first direction is arranged in parallel to the width direction of the air outlet 110.

[0075] There are many optional installation positions of the swing blade mechanism 200 on the air conditioner 100.
