[0025] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] The present invention provides a motion mechanism, please refer to Figures 1 to 4 , including: an air outlet frame 10, the air outlet frame 10 has an air outlet 11; an air guide plate 20, including an air guide plate body 21 and a rotating shaft 22 connected to the air guide plate body 21, the rotating shaft 22 is connected to the air outlet frame 10 and is rotatably arranged to drive the air guide plate 20 to rotate, so that the air guide plate 20 closes the air outlet 11 or opens the air outlet 11 to guide air; a supporting structure, one end of the supporting structure is connected to the air guide plate body 21, and the other end of the supporting structure is connected to the air outlet frame 10, the supporting structure has a first initial position and a supporting position for supporting the air guide plate 20, and the supporting structure is movably arranged to switch between the first initial position and the supporting position.

[0028] The motion mechanism of the present invention includes an air outlet frame 10, an air guide plate 20 and a support structure. The air guide plate 20 is used to guide the gas flowing out of the air outlet 11 of the air outlet frame 10; one end of the support structure is connected to the air guide plate body 21, and the other end of the support structure is connected to the air outlet frame 10. When the air guide plate body 21 is driven by the rotating shaft 22 to the air guide position, the support structure moves to the support position following the air guide plate body 21 to support the air guide plate 20 to prevent the air guide plate 20 from shaking when guiding the air; when the air guide plate body 21 is driven by the rotating shaft 22 to the second initial position closing the air outlet 11, the support structure moves to the first initial position following the air guide plate body 21. It can be seen that the motion mechanism solves the problem of the air guide plate shaking during air supply due to the excessively long cantilever through the setting of the support structure, ensures user experience, and the support structure will not interfere with the air guide plate during the position switching process.

[0029] In order to drive the supporting structure to move with the air deflector body 21 when the air deflector body 21 rotates, the supporting structure includes a connecting rod assembly 30, a first end of the connecting rod assembly 30 is connected to the air deflector body 21, and a second end of the connecting rod assembly 30 is connected to the air outlet frame 10.

[0030] In this embodiment, if Figure 2 As shown, the connecting rod assembly 30 includes a first connecting rod 31 and a second connecting rod 32. The first end of the first connecting rod 31 is hinged to the air guide plate body 21, the second end of the first connecting rod 31 is hinged to the first end of the second connecting rod 32, and the second end of the second connecting rod 32 is hinged to the air outlet frame 10.

[0031] In specific implementation, when the air guide body 21 moves to the air guide position, it stops. At this time, the first connecting rod 31 and the second connecting rod 32 tend to be almost straight (the supporting force on the air guide can offset the wind force on the air guide). At this time, the air guide is balanced and not easy to shake. This can ensure that the air supply distance is sufficient and prevent the air guide from shaking, thereby improving the user experience.

[0032] Specifically, a boss is provided at the first end of the second connecting rod 32, and the second end of the first connecting rod 31 is hinged to the boss. The boss is integrally formed with the second connecting rod 32. Such a configuration facilitates the connection between the first connecting rod 31 and the second connecting rod 32.

[0033] In order to realize the hinge connection between the first connecting rod 31 and the air deflector body 21, as shown in FIG. Figure 2 As shown, the air deflector 20 includes a protrusion 23 , which is disposed on the air deflector body 21 , and a first end of the first connecting rod 31 is hinged to the protrusion 23 .

[0034] In order to realize the hinge connection between the second connecting rod 32 and the air outlet frame 10, as shown in FIG. Figure 2As shown, the motion mechanism further includes a transition connector 40, which is detachably connected to the air outlet frame 10, and the second end of the second connecting rod 32 is hinged to the transition connector 40. The detachable connection between the transition connector 40 and the air outlet frame 10 facilitates the connection of transition connectors 40 of different sizes to the second connecting rod 32, thereby increasing the applicable range of the transition connector 40; and, it is convenient for processing the air outlet frame 10, thereby reducing production costs.

[0035] Specifically, the air outlet frame 10 is provided with a mounting hole; the transition connector 40 includes an inserting portion and a connecting portion 42 connected to the inserting portion, the inserting portion is inserted in the mounting hole, and the second end of the second connecting rod 32 is hinged to the connecting portion 42. Such a configuration facilitates the installation and removal of the transition connector 40 and the air outlet frame 10.

[0036] Specifically, the transition connector 40 or the air outlet frame 10 is provided with a limiting portion 41, which is used to limit the second connecting rod 32 so that the support structure is in the supporting position. Such a setting can limit the movement of the second connecting rod 32, so that after the air guide plate 20 is opened, the angle between the first connecting rod 31 and the second connecting rod 32 is less than 180°, thereby preventing the first connecting rod 31 and the second connecting rod 32 from approaching a dead point and being unable to close.

[0037] In this embodiment, there are two connecting rod assemblies 30, and the two connecting rod assemblies 30 are arranged on opposite sides of the air deflector body 21. In this way, there are four fulcrums on the entire air deflector associated with the air outlet frame, which further enhances the support effect of the air deflector and prevents the air deflector from vibrating significantly during operation. Correspondingly, there are two protrusions 23, limit portions 41 and transition connectors 40, so as to correspond one to one with the two connecting rod assemblies 30.

[0038] In this embodiment, the motion mechanism further includes a driving member 50 , which is connected to the rotating shaft 22 to drive the rotating shaft 22 to rotate.

[0039] Optionally, the driving member 50 is a stepper motor or a motor.

[0040] In this embodiment, the motion mechanism further includes a transmission component 60 , and the driving member 50 is connected to the rotating shaft 22 via the transmission component 60 , so that the driving member 50 drives the rotating shaft 22 to rotate via the transmission component 60 .

[0041] Optionally, the transmission component 60 is a gear transmission component.

[0042] Specifically, the first end of the rotating shaft 22 is inserted into the air outlet frame, the first end of the rotating shaft 22 is connected to the first gear 62, the first gear 62 is meshed with the second gear 61, the second gear 61 is connected to the driving member 50, the driving member 50 drives the second gear 61 to rotate, and then drives the first gear 62 and the rotating shaft 22 to rotate.

[0043] Specifically, the second end of the rotating shaft 22 is inserted into the air outlet frame 10, and the second end of the rotating shaft 22 is connected to the air outlet frame through a sleeve 70. Such a setting realizes the axial positioning of the two, and facilitates the rotation of the rotating shaft 22 to avoid the wear of the air outlet frame. In other embodiments, the sleeve 70 can also be eliminated, and a transmission mechanism of a driving member 50 and a transmission component 60 is also set at the second end of the rotating shaft 22 to move synchronously with the driving member 50 and the transmission component 60 at the first end of the rotating shaft 22.

[0044] The present invention further provides an air-conditioning indoor unit, comprising a motion mechanism, wherein the motion mechanism is the motion mechanism in the above embodiment.

[0045] Specifically, the air-conditioning indoor unit is an upward and downward air-discharging type air-conditioning indoor unit, that is, the air-conditioning indoor unit can discharge air upward alone, can discharge air downward alone, or can discharge air upward and downward simultaneously.

[0046] The motion mechanism of the present application solves the problem of the air guide plate shaking when the indoor unit of the air conditioner is working.

[0047] The air conditioner indoor unit of the present application realizes long-distance air supply by adopting a larger-sized air guide plate. At the same time, a connecting rod assembly 30 is used to support the air guide plate, and the cantilever of the air guide plate is shortened to prevent the air guide plate from shaking during operation.

[0048] This application mainly uses the gear transmission mechanism and the connecting rod linkage structure to achieve the smooth movement and anti-shake of the large air guide plate. The connecting rod assembly 30 connects the air guide plate 20 and the air outlet frame 10 together. The gear transmission structure serves as the running carrier of the air guide plate. The stepper motor drives the gear to drive the air guide plate to operate. Figure 4 As shown, when the air guide plate is opened, the air guide plate drives the connecting rod assembly to move upward, and stops moving after reaching the highest point. The motor provides an upward rotational torque to prevent the air guide plate from shaking downward due to the influence of gravity G. At the same time, the first connecting rod 31 and the second connecting rod 32 tend to the same straight line to provide support and tensioning effect (i.e., tension F2) for the air guide plate, balancing the effect of wind force F1 on the air guide plate, and solving the problem of vibration during operation of the large air guide plate.

[0049] Specifically, the working principle is that when the air conditioner indoor unit is turned on, the stepper motor starts to drive the air guide plate to move through the gear transmission mechanism, driving the connecting rod assembly to swing upward until the air guide plate is opened to the maximum angle. At this time, the first connecting rod and the second connecting rod will tend to a straight line (the angle between the two connecting rods is less than 180° to prevent the two connecting rods from approaching a dead point and being unable to close). At this time, the connecting rod assembly supports and pulls the air guide plate, and this force can offset the effect of the wind force F1 on the air guide plate (the force analysis is as follows Figure 4 As shown in the figure, this pulling force F2 changes with the magnitude of the wind force F1. At the same time, it is subjected to the reaction force F3 of the motor rotation. This ensures that the force on the air guide plate is balanced and prevents the air guide plate from shaking when the air conditioner is working.

[0050] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0051] The motion mechanism of the present invention includes an air outlet frame 10, an air guide plate 20 and a support structure. The air guide plate 20 is used to guide the gas flowing out of the air outlet 11 of the air outlet frame 10; one end of the support structure is connected to the air guide plate body 21, and the other end of the support structure is connected to the air outlet frame 10. When the air guide plate body 21 is driven by the rotating shaft 22 to the air guide position, the support structure moves to the support position following the air guide plate body 21 to support the air guide plate 20 to prevent the air guide plate 20 from shaking when guiding the air; when the air guide plate body 21 is driven by the rotating shaft 22 to the second initial position closing the air outlet 11, the support structure moves to the first initial position following the air guide plate body 21. It can be seen that the motion mechanism solves the problem of the air guide plate shaking during air supply due to the excessively long cantilever through the setting of the support structure, ensures user experience, and the support structure will not interfere with the air guide plate during the position switching process.
