Referring to fig. 1 and 2, an air conditioner according to an embodiment of the present utility model includes a housing 110 and an air guide plate driving mechanism installed in the housing 110. The air deflector driving structure comprises a fixing seat 10, a telescopic shearing fork frame 20 and an air deflector 30, wherein the fixing seat 10 is fixedly arranged on the inner surface of a shell 110, one end of the shearing fork frame 20 is connected with the fixing seat 10, and the other end of the shearing fork frame is connected with the air deflector 30, so that when the shearing fork frame 20 stretches, the shearing fork frame 20 drives the air deflector 30 to stretch out or retract relative to the fixing seat 10.

Referring to fig. 2, when the scissor frame 20 is retracted relative to the fixing seat 10, the air outlet 111 can be closed by the air deflector 30, and the air conditioner is in a closed state at this time, and the air outlet 111 is closed by the air deflector 30 to prevent dust from entering the air conditioner. When the scissor frame 20 extends out of the fixing base 10, referring to fig. 2, the air deflector 30 is separated from the air outlet 111 and moves in a direction away from the air outlet 111, so that the air outlet 111 is in an open state, and at this time, the air conditioner is in an open state, and cool air or warm air generated by the air conditioner is blown out through the air outlet 111.

Further, referring to fig. 2 and 3, the distance between the air deflector 30 and the air outlet 111 is adjusted by adjusting the telescopic length of the scissor frame 20, so as to adjust the air outlet range of the air outlet 111. Specifically, when the length of the scissor frame 20 extending out of the fixing base 10 is longer, the distance between the air deflector 30 and the air outlet 111 is longer, and the smaller the range of the air outlet 111 blocked by the air deflector 30 is, the larger the air outlet range of the air outlet 111 is. And when the length of the scissor frame 20 extending out of the fixing base 10 is smaller, the distance between the air deflector 30 and the air outlet 111 is shorter, and the larger the range of the air outlet 111 shielded by the air deflector 30 is, the smaller the air outlet range of the air outlet 111 is. Thus, in the actual use process, when the user needs to adjust the air outlet range of the air conditioner, the telescopic length of the scissor frame 20 can be adjusted, so as to adjust the air outlet range of the air outlet 111.

Furthermore, the scissors frame 20 generally adopts a plurality of movable rods which are disposed to cross each other, i.e. the first movable rod 25, the second movable rod 26 and the third movable rod 27, which are described below, are not provided with gears or arc racks, so that the difficulty in processing the scissors frame 20 can be greatly reduced, and if the movable rods are further processed and manufactured by adopting materials such as plastics, the manufacturing cost of the scissors frame 20 can be further reduced, and the manufacturing difficulty of the driving mechanism of the air deflector can be further reduced.

Above-mentioned aviation baffle actuating mechanism drives aviation baffle 30 through the flexible of shearing fork 20 and stretches out and retract to realize that aviation baffle 30 opens or closes air outlet 111, compare in traditional mode that adopts the motor to drive gear drive arc rack motion, through the flexible mode of shearing fork 20, need not processing gear or arc rack, greatly reduced aviation baffle actuating structure's manufacturing degree of difficulty.

In the embodiment of the present utility model, the scissors frame 20 can controllably rotate around an axis relative to the fixed base 10, and the axis intersects the telescopic direction of the scissors frame 20 and is parallel to the longitudinal direction of the air deflector 30. Therefore, when the scissor frame 20 stretches and contracts, the air deflector 30 is close to or far away from the air outlet 111, when the scissor frame 20 rotates relative to the fixed seat 10, the air deflector 30 rotates relative to the air outlet 111, if the scissor frame 20 rotates relative to the fixed seat 10 while stretching and contracting, the air deflector 30 can rotate relative to the air outlet while approaching or far away from the air outlet 111, namely, the air deflector 30 can do arc motion relative to the air outlet 111. Therefore, besides the movement process of the air deflector 30 is more beautiful, the scissors frame 20 can avoid interference with other parts in the air conditioner, such as the shell 110, through rotation during the expansion process, so that the movement of the scissors frame 20 is more flexible.

Specifically, in the embodiment of fig. 1, the expansion and contraction direction is the X direction, i.e., the up-down direction, and the longitudinal direction of the air deflector 30 is the Y direction, i.e., the left-right direction.

In some embodiments, referring to fig. 2 and 5, the scissors assembly 20 includes a first end 21 and a second end 22 opposite to each other along a telescopic direction, the second end 22 is connected to the air deflector 30, the first end 21 includes a first telescopic end 28 and a second telescopic end 29, the first telescopic end 28 is fixedly mounted on the fixing base 10, the second telescopic end 29 is controllably movable along an arc, and a center of the arc is spaced from the first telescopic end 28, that is, the second telescopic end 29 does not move circumferentially around the first telescopic end 28, so that the second telescopic end 29 moves relatively to the first telescopic end 28 during movement, that is, the second telescopic end 29 moves closer to or away from the first telescopic end 28, and when the second telescopic end 29 moves closer to the first telescopic end 28, the scissors assembly 20 stretches, and when the second telescopic end 29 moves away from the first telescopic end 28, the scissors assembly 20 shortens.

The second telescopic end 29 moves along the arc line, and simultaneously, the second telescopic end 28 moves relatively to the first telescopic end, and drives the scissor frame 20 to rotate relatively to the fixed seat 10, the air deflector 30 also rotates along with the fixed seat 10, and the air deflector 30 can rotate in conjunction with the relative movement of the first telescopic end 28 and the second telescopic end 29 when extending or retracting, namely, the air deflector 30 moves in an arc line relatively to the air outlet 111.

In the embodiment, the fixing base 10 is further provided with a limiting groove 11 extending along the arc in a longitudinal direction, the first telescopic end 28 is movably installed in the limiting groove 11, the moving mode of the first telescopic end 28 can be directly driven by a motor and a connecting rod, and the limiting groove 11 can limit the movement of the first telescopic end 28, so that the movement of the first telescopic end 28 is smoother.

Further, in order to reduce the space occupied by the first telescopic end 28 in the housing 110, the air deflector driving mechanism further includes a power source 31, a first connecting rod 32 and a second connecting rod 33, the power source 31 may be a motor, an output shaft of the power source 31 is connected with one end of the first connecting rod 32, the other end of the first connecting rod 32 is connected with one end of the second connecting rod 33, and the other end of the second connecting rod 33 is hinged with the first telescopic end 28. In this way, the power source 31, the first connecting rod 32, the second connecting rod 33 and the limiting groove 11 together form a crank-slider mechanism, so that the rotation of the output shaft of the power source 31 is converted into the movement of the first telescopic end 28 along the limiting groove 11.

Further, the length of the first connecting rod 32 is smaller than that of the second connecting rod 33, so that the internal space of the housing 110 occupied by the rotation of the first connecting rod 32 is reduced, the first connecting rod 32 can only swing within a certain range relative to the fixing seat 10, and does not occupy excessive internal space of the housing 110, and therefore, the normal extension and retraction of the air deflector 30 can be ensured and the installation space in the housing 110 can be saved through the crank slider mechanism.

The plurality of first scissors structures 23 form a main telescopic part of the scissors assembly 20, two first movable rods 25 of the first scissors structure 23 at the head end deviate from two ends of the adjacent first scissors structure 23 to serve as a first telescopic end 28 and a second telescopic end 29 respectively, and when the first telescopic end 28 and the second telescopic end 29 are close to or far away from each other, the two first movable rods 25 of the other first scissors structure 23 can be driven to be close to or far away from each other, so that the whole scissors assembly 20 can be lengthened or shortened.

The second scissor structure 24 comprises a second movable rod 26 and a third movable rod 27, wherein the middle end of the second movable rod 26 is hinged with one end of the third movable rod 27, the other end of the third movable rod 27 is hinged with one of the first movable rods 25 of the first scissor structure 23 at the tail end, one end of the second movable rod 26 is hinged with the other movable rod of the first scissor structure 23 at the tail end, and the other end of the second movable rod is connected with the air deflector 30. In this way, when the two first movable rods 25 in each first scissor structure 23 approach to or separate from each other, the second movable rod 26 and the third movable rod 27 of the second scissor structure 24 can be driven to approach to or separate from each other, so that the air deflector 30 connected with the second movable rod 26 is extended or retracted.

If the second fork structure 24 and the first fork structure 23 have the same structure, the second fork structure 24 has one more end, which is easy to interfere with other components of the air conditioner during the movement of the air deflector 30, so as to block the movement of the air deflector 30. For this reason, the second scissor structure 24 adopts a manner that the end of the third movable rod 27 is hinged to the second movable rod 26, so that the second scissor structure 24 has three ends, and no redundant ends exist, which not only saves the installation space of the second scissor structure 24, but also prevents the redundant ends from influencing the movement of the air deflector 30.

In the embodiment, the second movable rod 26 is hinged to the air deflector 30, so that the air deflector 30 can rotate relative to the second movable rod 26, and when the air outlet 111 blows air in different directions, the air deflector 30 can also rotate relative to the air outlet 111 to adapt to the air flows in different directions.

The following describes the movement process of the air deflector driving mechanism in the embodiment of the present utility model with reference to fig. 2, 3 and 4.

Referring to fig. 2, the air guide plate driving mechanism is in an initial state, the air guide plate 30 closes the air outlet 111, and the air conditioner is in a closed state. When the air conditioner is turned on, referring to fig. 2, the power source 31 drives the first connecting rod 32 to rotate anticlockwise, and the first connecting rod 32 drives the second telescopic end 29 to move in the arc-shaped slot through the second connecting rod 33 and to approach the first telescopic end 28, so that the scissor frame 20 rotates while extending to drive the air deflector 30 to extend out of the air outlet 111 and rotate relative to the air outlet 111.
