Embodiment 1:

1-11 and 18 , an embodiment of the present disclosure provides a driving mechanism for an air guide plate 30 of an air conditioner.

The air conditioner includes an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected by a connecting pipe to realize the circulation of refrigerant between the indoor unit and the outdoor unit.

The indoor unit includes a housing 100, which defines an air duct and is provided with an air inlet and an air outlet 1001 connected to the air duct. A heat exchanger and a fan are provided in the air duct. Driven by the fan, air enters from the air inlet, exchanges heat with the heat exchanger, and is blown out from the air outlet 1001.

The indoor unit further includes an air guide plate 30 , which is movably disposed at the air outlet 1001 for opening or closing the air outlet 1001 .

Optionally, the driving mechanism includes a first connecting rod 10 and a second connecting rod 20 .

The first connecting rod 10 is configured to be movably connected to the air guide plate 30 and to make a linear motion along its own length direction; the second connecting rod is configured to be movably connected to the air guide plate 30 and to make a linear motion along its own length direction.

The first connecting rod 10 and the second connecting rod 20 are sequentially arranged along the width direction of the air guide plate 30, and the first connecting rod 10 and the second connecting rod 20 are both movably connected to the air guide plate 30. This arrangement allows the opening and closing requirements of the air guide plate 30 to be met when the first connecting rod 10 and the second connecting rod 20 both move linearly.

The first connecting rod 10 and the second connecting rod 20 work together to enable the air guide plate 30 to move between the closed position and the open position (as shown in FIG. 18 ).

The open position includes a first open position and a second open position. In the first open position, the wind guide surface 301 of the wind guide plate 30 faces the first wind guide direction, and in the second open position, the wind guide surface 301 of the wind guide plate 30 faces the second wind guide direction, and one of the first wind guide direction and the second wind guide direction faces upward, and the other faces downward. That is, as shown in Figures 7 and 8, the first wind guide direction faces downward, as shown in Figures 5 and 6, the second wind guide direction faces upward, or the first wind guide direction faces upward and the second wind guide direction faces downward, so as to achieve the flipping of the wind guide plate 30.

As shown in FIG. 18 , in the closed position, the air guide plate 30 closes the air outlet 1001. Taking the first air guide direction downward and the second air guide direction upward as an example, in the first open position, the air guide surface 301 of the air guide plate 30 faces downward, which is suitable for guiding the hot air flowing out of the air outlet 1001 to flow downward during heating. In the second open position, the air guide surface 301 faces upward, which is suitable for guiding the cold air flowing out of the air outlet 1001 to flow upward during cooling. Since the air guide plate 30 has a first open position and a second open position, the air conditioner has multiple air outlet modes.

Optionally, as shown in Figure 3, the first connecting rod 10 includes a first end 109 and a second end 110 in the length direction, and the first end is movably connected to the wind guide plate 30; the second connecting rod 20 includes a third end 206 and a fourth end 207 in the length direction, and the third end is movably connected to the wind guide plate 30; wherein the distance between the first end and the third end is smaller than the distance between the second end and the fourth end.

The wind guide surface 301 is provided with a first connection part and a second connection part, the first connection part is movably connected to the first connecting rod 10, and the second connection part is movably connected to the second connecting rod 20. The first connection part can be a first protrusion 302 or a first depression, and the second connection part can be a second protrusion 304 or a second depression.

The distance between the first end and the third end is smaller than the distance between the second end and the fourth end. Under the condition that the air deflector 30 can have the first open position and the second open position, the first connection portion and the second connection portion need to be close to the middle of the width direction of the air deflector 30. Compared with the first connection portion and the second connection portion being arranged at the ends of the width direction of the air deflector 30, the first connection portion and the second connection portion need to be close to the middle of the width direction of the air deflector 30 to reduce the movement stroke of the first connecting rod 10 and the second connecting rod 20 during the opening of the air deflector 30, thereby reducing the space occupied by the first connecting rod 10 and the second connecting rod 20.

The second end is located inside the first end, and the fourth end is located inside the third end, wherein the direction close to the interior of the indoor unit is the inside, and the direction away from the interior of the indoor unit is the outside. As shown in FIG3 , the first connecting rod 10 and the second connecting rod 20 both extend approximately along the length direction of the air duct, and the first connecting rod 10 and the second connecting rod 20 respectively make linear motions along their own length directions, which can be understood as the first connecting rod 10 and the second connecting rod 20 making linear motions approximately along the length direction of the air duct.

The motion trajectory of the first connecting rod 10 is a first straight line, and the motion trajectory of the second connecting rod 20 is a second straight line. Along the extension direction of the first connecting rod 10 and the second connecting rod 20, the first straight line approaches the second straight line, and the second straight line approaches the first straight line, so that the distance between the first straight line and the second straight line decreases.

Optionally, as shown in Figures 2 and 4, the driving mechanism also includes a limit member 70, which is provided with a first limit portion 105 and a second limit portion 202; the first connecting rod 10 is provided with a first limit fitting portion 702 that cooperates with the first limit portion 105, and the second connecting rod 20 is provided with a second limit fitting portion 703 that cooperates with the second limit portion 202; the first limit portion 105 cooperates with the first limit fitting portion 702 and can move relative to the first limit fitting portion 702 to guide the first connecting rod 10 to make a linear motion relative to the limit member 70 along its own length direction, and the second limit portion 202 cooperates with the second limit fitting portion 703 and can move relative to the second limit fitting portion 703 to guide the second connecting rod 20 to make a linear motion relative to the limit member 70 along its own length direction.

The first limiting portion 105 and the first limiting matching portion 702 can not only realize the installation of the first connecting rod 10 on the limiting member 70, but also guide the first connecting rod 10 to perform telescopic movement in its own length direction to avoid deviation of the first connecting rod 10 during movement.

As shown in Figures 3, 7 and 8, when moving from the closed position to the first open position, the first link 10 and the second link 20 respectively extend outward along their own length directions, and the first link 10 and the second link 20 can perform a larger differential movement. At this time, for example, the first link 10 extends faster and the second link 20 extends slower, so that the air guide plate 30 flips to the first open position.

The wind guide surface 301 is also provided with a second protrusion 304, and the second connecting rod 20 is rotatably connected to the second protrusion 304 via the second rotating shaft 205.

The first rotating shaft 108 and the second rotating shaft 205 are staggered and arranged in sequence along the width direction of the air guide plate 30, so that the air guide plate 30 can be flipped from the closed position to the first open position, and can be flipped from the first open position to the second open position.

The first rotating shaft 108 and the second rotating shaft 205 are both parallel to the length direction of the air guide plate 30 .

As shown in Figures 12 and 14, when moving from the closed position to the first open position, the first link 10 and the second link 20 respectively extend outward along their own length directions, and the first link 10 and the second link 20 can perform a larger differential movement. At this time, for example, the first link 10 extends faster and the second link 20 extends slower, so that the air guide plate 30 flips to the first open position.

For example, the first connecting rod 10 retracts into the air duct along its own length direction, and the second connecting rod 20 continues to extend along its own length direction, so that the air guide plate 30 is flipped to the second open position.

The following describes the opening process of the air guide plate 30 in the present application by taking the example that the air guide plate 30 passes through the closed position, the first open position and the second open position in sequence during the opening process, and the first connecting rod 10 is located above the second connecting rod 20.

As shown in Figures 15 and 17, when moving from the closed position to the first open position, the first link 10 and the second link 20 respectively extend outward along their own length directions, and the first link 10 and the second link 20 can perform a larger differential movement. At this time, for example, the first link 10 extends slower and the second link 20 extends faster, so that the air guide plate 30 flips to the first open position.

As shown in FIG. 16 , when the air guide plate 30 moves from the first open position to the second open position, the first connecting rod 10 continues to extend along its own length direction, and the second connecting rod 20 stops moving.
