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.

[0032] The present invention provides a motion mechanism, please refer to Figures 1 to 10, 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 as to close the air outlet 11 or open the air outlet 11 and guide the air; a motion component 40, including a moving part 42, the moving part 42 performs reciprocating linear motion; a support member 30, the support member 30 has a first position supporting the air guide plate 20 and a avoidance position avoiding the air guide plate 20; the first end of the support member 30 is connected to the air guide plate body 21, and the second end of the support member 30 is connected to the moving part 42, so that the support member 30 switches between the first position and the avoidance position.

[0033] The motion mechanism of the present invention includes an air outlet frame 10, an air guide plate 20, a motion component 40 and a support member 30. The air guide plate 20 is used to close the air outlet 11 or open the air outlet 11 and guide the air; the support member 30 follows the movement of the air guide plate 20 and the motion component 40 to switch between the first position and the avoidance position, so as to support the air guide plate 20 when the air guide plate 20 is opened to sweep the air, thereby avoiding the air guide plate 20 from shaking when supplying air; and the reciprocating linear motion of the moving part 42 drives the support member 30 to switch between the first position and the avoidance position with high reliability, and no jamming or failure problems will occur.

[0034] Specifically, compared to the structure that uses a connecting rod assembly to support the air guide plate 20, that is, one end of the connecting rod assembly is hinged to the air outlet frame 10, and the other end of the connecting rod assembly is hinged to the air guide plate body 21, the motion mechanism drives the support member 30 to switch between the first position and the avoidance position through the moving part 42 that performs reciprocating linear motion, and has high reliability and will not cause problems of jamming or failure.

[0035] In this embodiment, the motion assembly 40 includes a first transmission wheel 411, a second transmission wheel 412 and a conveyor belt 413. The conveyor belt 413 is sleeved on the first transmission wheel 411 and the second transmission wheel 412. The first transmission wheel 411 and the second transmission wheel 412 are both rotatably arranged to drive the conveyor belt 413 to move. The moving part 42 is a part of the belt body of the conveyor belt 413. Such an arrangement can drive the support member 30 to move through the reciprocating linear motion of the part of the belt body of the conveyor belt 413, and the transmission reliability of the conveyor belt is relatively high.

[0036] In this embodiment, the first transmission wheel 411 is connected to the rotating shaft 22 to drive the rotating shaft 22 to rotate. Such an arrangement can drive the rotating shaft 22 and the support member 30 to move together through the motion assembly 40, and the transmission linkage and the compact structure are high.

[0037] In this embodiment, the motion mechanism further includes a driving member 43, which is connected to the first transmission wheel 411 to drive the first transmission wheel 411 to rotate. Specifically, the first transmission wheel 411 rotates as a driving wheel to drive the conveyor belt 413 to move forward and backward.

[0038] In this embodiment, the first end of the support member 30 is hinged to the deflector body 21, and the second end of the support member 30 is hinged to the moving portion 42. This arrangement allows the support member 30 to follow the movement of the deflector body 21 and the moving portion 42 to achieve position switching.

[0039] In this embodiment, the movable part 42 is provided with a mounting groove 421, and the second end of the support member 30 is provided with a clamping part 31, which is arranged in the mounting groove 421 and rotatably arranged relative to the movable part 42. Such an arrangement realizes the hinge connection between the support member 30 and the movable part 42.

[0040] Specifically, the movable portion 42 has a groove matched with the structure of the clamping portion 31 , and the clamping portion 31 is clamped into the movable portion 42 , thereby driving the air guide plate to open and close, which can ensure reliable movement without getting stuck.

[0041] In this embodiment, the moving part 42 is provided with an escape hole 422, which is connected to the mounting groove 421, and extends along the moving direction of the moving part 42 to accommodate the support member 30. Such a setting can make the support member 30 avoid the support member 30 when the support member 30 swings relative to the moving part 42, thereby providing a movable space for the support member 30.

[0042] Optionally, the avoidance hole 422 is a countersunk hole or a through hole.

[0043] Optionally, the support member 30 is a rod-shaped structure or a plate-shaped structure.

[0044] In this embodiment, there are two motion components 40, which are arranged on the air outlet frame 10, and the two motion components 40 are arranged on opposite sides of the air outlet 11; there are two support members 30, which are arranged one-to-one with the two motion components 40, and each support member 30 is connected to the corresponding motion component 40. Such an arrangement further improves the reliability of the motion component and prevents the air guide plate from shaking.

[0045] In specific implementation, the application mainly uses a conveyor belt, a first transmission wheel and a second transmission wheel to realize the opening and closing of the air guide plate, and the conveyor belt supports the connecting rod (i.e., the support member) to prevent the air guide plate from shaking. The movement mode is as follows Figure 2 and Figure 3As shown; when the moving component moves, the air guide plate is connected to the conveyor belt and stops when it reaches the highest point. At this time, the support and the conveyor belt support the air guide plate to prevent it from shaking. This can ensure that the air supply distance is sufficient and prevent the air guide plate from shaking, thereby improving the user experience.

[0046] In specific implementation, the first transmission wheel 411 rotates clockwise to drive the conveyor belt and the second transmission wheel 412 to rotate, thereby pulling the support member 30 to move, and finally closing the air guide plate. When the air guide plate is opened, the first transmission wheel 411 rotates counterclockwise to drive the conveyor belt to rotate, pulling the support member 30 and the air guide plate to open. The conveyor belt mechanism moves smoothly, which can ensure reliable and stable movement. At the same time, Figure 4 As shown, when the air guide plate is in the open state, the air guide plate is subjected to the gravity G, the force F1 of the wind and the pulling force F2 of the connecting rod (i.e., the support member 30, the same below). When the air-conditioning indoor unit is working normally, the force of the wind acting on the air guide plate is relatively large, and the air guide plate tends to lift upward. At this time, because the connecting rod is connected to the air guide plate and the conveyor belt, the connecting rod generates a pulling force on the air guide plate, and the pulling force of the connecting rod changes with the change of the force of the wind. Therefore, the three forces shown in the figure can be balanced to ensure that the air guide plate will not shake.

[0047] 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.

[0048] The present application solves the following technical problems: solves the problem of the air guide plate shaking when the air conditioner is working, and solves the problem of unreliable movement of the supporting parts of the air guide plate.

[0049] The beneficial effects of the present application are as follows: the upper and lower air-outlet air-conditioning indoor units can realize long-distance air supply by adopting a large air guide plate, and at the same time adopt a pulley-type motion mechanism to ensure reliable and smooth movement without jamming. At the same time, a pulley structure and a connecting rod structure are used to support the air guide plate to prevent the air guide plate from shaking.

[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, a motion component 40 and a support member 30. The air guide plate 20 is used to close the air outlet 11 or open the air outlet 11 and guide the air; the support member 30 follows the movement of the air guide plate 20 and the motion component 40 to switch between the first position and the avoidance position, so as to support the air guide plate 20 when the air guide plate 20 is opened to sweep the air, thereby avoiding the air guide plate 20 from shaking when supplying air; and the reciprocating linear motion of the moving part 42 drives the support member 30 to switch between the first position and the avoidance position with high reliability, and no jamming or failure problems will occur.
