[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] Reference below Figure 1-Figure 14 The air guide plate assembly 100 and the air conditioner according to the embodiment of the present invention are described.

[0040] like Figure 1 , Figure 2 , Fig.11 , Fig.12 As shown, the air deflector assembly 100 according to the first embodiment of the present application includes: an air deflector 10, a first transmission assembly 20, a second transmission assembly 30 and a power source 40.

[0041] Among them, the first flip center 111 and the second flip center 112 are respectively formed on the upper and lower sides of the air guide plate 10, the first transmission assembly 20 is connected to the air guide plate 10 at the first flip center 111, and the first transmission assembly 20 is used to drive the air guide plate 10 to flip along the second flip center 112, the second transmission assembly 30 is connected to the air guide plate 10 at the second flip center 112, and the second transmission assembly 20 is used to drive the air guide plate 10 to flip along the first flip center 111, and the power source 40 has a power output end, which is selectively connected to the first transmission assembly 20 or the second transmission assembly 30 for power.

[0042] Specifically, the air guide plate assembly 100 is arranged on the air outlet area of ​​air conditioners, air coolers and other air flow processing equipment, and can open or cover the air outlet. The upper side of the air guide plate 10 is formed with a first flip center 111, and the lower side of the air guide plate 10 is formed with a second flip center 112. With the first flip center 111 as the axis, the second transmission assembly 30 drives the air guide plate 10 to rotate, so that the air guide plate 10 can be flipped to the first open position. At this time, the air guide plate 10 is located above the air outlet (see Figure 7 ), with the second flip center 112 as the axis, the first transmission assembly 20 drives the air guide plate 10 to rotate, so that the air guide plate 10 can be flipped to the second open position, at which time the air guide plate 10 is located below the air outlet (see Figure 8 ) so that the air guide plate 10 can move from above the air outlet to below the air outlet, or from below the air outlet to below the air outlet, so as to achieve large-angle air supply, a larger air supply range, better processing effect, and higher user experience.

[0043] Furthermore, a power source 40 is provided, and the power output end of the power source 40 is selectively connected to the first transmission component 20 and the second transmission component 30 by power. That is, the first transmission component 20 is connected to the power source 40 by power, so that the air guide plate 10 can be flipped around the second flip center 112 as the axis and flipped to the second open position. When the second transmission component 30 is connected to the power source 40 by power, the air guide plate 10 can be flipped around the first flip center 111 as the axis and flipped to the first open position. A power source 40 can drive the two groups of transmission components to selectively move in time to realize the switching of the air guide plate 10 between the first open position and the second open position. There is no need to set up multiple power sources 40, which can simplify the structure of the air guide plate assembly 100 and reduce the cost of the air guide plate assembly 100.

[0044] It can be understood that the selective power connection between the power output end and the first transmission component 20 and the second transmission component 30 means that the power output end is selectively power-connected with the first transmission component 20 and the second transmission component 30. The power connection can be direct transmission between the two, such as: meshing, belt drive, cam slider, etc., or it can be indirect transmission through other structures, such as: the power output end directly drives the first transmission component 20, and the first transmission component 20 selectively drives the second transmission component 30.

[0045] It should be pointed out that when the air guide plate 10 is in the first open position, it can discharge air downward, which is suitable for supplying air in the heating mode; when it is in the second open position, it can discharge air upward, which is suitable for supplying air in the cooling mode, and can also increase the indoor stratified temperature to improve comfort.

[0046] According to the air deflector assembly 100 of the embodiment of the present application, on the one hand, the air deflector 10 has a first flip center 111 and a second flip center 112, and the air deflector 10 can be switched between a first open position and a second open position through the first transmission assembly 20 and the second transmission assembly 30, so that the movement angle of the air deflector 10 is larger, and large-angle air supply can be achieved, thereby improving the temperature regulation effect and the user experience; on the other hand, by driving the two transmission assemblies with one power source 40, the structure of the air deflector assembly 100 can be simplified and the cost of the air deflector assembly 100 can be reduced.

[0047] It should be pointed out that the air guide plate with only one rotation center in the prior art cannot achieve large-angle air guide in different modes. For example, when switching from cooling mode to heating mode, the air guide plate with only one rotation center can only rotate downward to further open the air guide plate, but after opening to the maximum degree, it cannot be opened further due to the structure, and the air guide line of the air guide plate is still bent upward, and the effect of pressing the hot air downward is not improved. The air guide plate 10 of the present application solution can selectively flip with the first flip center 111 as the axis when heating, and flip with the second flip center 112 as the axis when cooling, so as to realize the upward delivery of cold air and the downward pressure of hot air, and construct an air guide line that is more suitable for cooling and heating.

[0048] It can be understood that the power source 40 drives the first transmission assembly 20 and the second transmission assembly 30 to realize the flipping of the air guide plate 10. When the power source 40 rotates clockwise, it drives the air guide plate 10 to rotate from the closed position to the first open position. When it rotates counterclockwise, the air guide plate 10 is first reset to the closed position, and then drives the air guide plate 10 to rotate to the second open position. The power source 40 can also rotate in a fixed direction (counterclockwise or clockwise), and the air guide plate 10 reciprocates between the first open position and the second open position.

[0049] like Figure 3 , Figure 4 , Fig.10 , Fig.13 , Fig.14 According to some embodiments of the present application, the first transmission assembly 20 has a first input shaft 21 , and the second transmission assembly 30 has a second input shaft 31 . The first input shaft 21 and the second input shaft 31 are selectively connected to the power source 40 .

[0050] Exemplarily, the power source 40 can be configured as a drive motor, the first input shaft 21 and the second input shaft 31 can be configured as gear shafts, the drive motor engages with the gear shaft through the power output end to achieve power transmission, or the first input shaft 21 and the second input shaft 31 can be configured as camshafts, and the power output end is connected to the camshaft to achieve power transmission.

[0051] It can be understood that the first input shaft 21 and the second input shaft 31 can be selectively connected to the power output end, which can improve the stability and reliability of power transmission and enhance the working stability of the air guide plate assembly 100.

[0052] Below, two feasible transmission structures of the present application are specifically described with two specific embodiments.

[0053] like Fig.10 As shown, in the first embodiment, according to some embodiments of the present application, the first input shaft 21 is coaxially arranged with the second input shaft 31, and the power output end is constructed as a stacked first gear 42 and a second gear 43, and the first gear 42 and the second gear 43 are both constructed as incomplete gears, so that the first gear 42 is selectively engaged with the first input shaft 21, and the second gear 43 is selectively engaged with the second input shaft 31, and the meshing tooth segment of the first gear 42 is staggered with the meshing tooth segment of the second gear 43.

[0054] Specifically, the first input shaft 21 and the second input shaft 31 are coaxially arranged, and the first input shaft 21 can be nested on the second input shaft 31, or the second input shaft 31 can be nested on the first input shaft 21. The first input shaft 21 and the second input shaft 31 can rotate separately without interfering with each other, and the first gear 42 and the second gear 43 are both constructed as incomplete gears. The power source 40 drives the first gear 42 and the second gear 43 to rotate synchronously. When the meshing tooth segment of the first gear 42 meshes with the first input shaft 21 and the smooth tooth segment of the second gear 43 is opposite to the second input shaft 31, the first transmission assembly 20 is connected to the power output end, and the second transmission assembly 30 is connected to the power output end. The power transmission between the output ends is interrupted, and the first transmission component 20 drives the air guide plate 10 to rotate around the second flip center 112. When the smooth tooth segment of the first gear 42 is opposite to the first input shaft 21 and the meshing tooth segment of the second gear 43 is meshed with the second input shaft 31, the power transmission between the first transmission component 20 and the power output end is interrupted, and the second transmission component 30 drives the air guide plate 10 to rotate around the first flip center 111, so as to realize the time-sharing transmission of the first transmission component 20 and the second transmission component 30 through the selectable power connection between two incomplete gears and two gear shafts, and the time-sharing transmission can be realized by only one power source 40, which effectively simplifies the structure of the air guide plate assembly 100 and reduces the cost.

[0055] like Fig.13 and Fig.14 As shown, in the second embodiment, in some embodiments, the power output end is constructed as a power output gear 41, the power output gear 41 is constructed as an incomplete gear, the first input shaft 21 and the second input shaft 31 are both constructed as gear shafts, and are located on the peripheral side of the power output gear 41, so that the power output gear 41 selectively engages with the first input shaft 21 or the second input shaft 31.

[0056] Among them, the meshing of the power output gear 41 with the first input shaft 21 and the second input shaft 31 in the second embodiment can achieve the same technical effect as the meshing of the first gear 42 and the second gear 43 with the first input shaft 21 and the second input shaft respectively in the first embodiment.

[0057] Specifically, the axis center of the first input shaft 21, the axis center of the second input shaft 31, and the rotation center of the power output gear 41 are located on the same straight line. During the rotation of the power output gear 41, when the meshing tooth segment is meshed with the first input shaft 21, the smooth tooth segment is opposite to the second input shaft 31, so that the first transmission component 20 outputs power, and when the meshing tooth segment is meshed with the second input shaft 31, the smooth tooth segment is opposite to the first input shaft 21, so that the second transmission component 30 outputs power.

[0058] like Figure 5 , Figure 6 , Fig. 9 , Fig.11 and Fig.12 As shown, in some embodiments, the first transmission assembly 20 also includes: a first connecting rod 22 and a second connecting rod 23, one end of the first connecting rod 22 is connected to the first input shaft 21, the other end of the first connecting rod 22 is connected to one end of the second connecting rod 23, the other end of the second connecting rod 23 is connected to the first flip center 111, and the second transmission assembly 30 also includes: a third connecting rod 32 and a fourth connecting rod 33, one end of the third connecting rod 32 is connected to the second input shaft, the other end of the third connecting rod 32 is connected to one end of the fourth connecting rod 33, and the other end of the fourth connecting rod 33 is connected to the second flip center 112.

[0059] Thus, the first input shaft 21 can drive the first connecting rod 22, the first connecting rod 22 drives the second connecting rod 23, the second connecting rod 23 pushes the air guide plate 10 to rotate around the second flip center 112, the second input shaft 31 can drive the third connecting rod 32, the third connecting rod 32 drives the fourth connecting rod 33, the fourth connecting rod 33 pushes the air guide plate 10 to rotate around the first flip center 111, which can improve the power transmission stability of the first transmission assembly 20 and the second transmission assembly 30, and make the movement smoother of the air guide plate 10 between the first open position, the second open position and the closed position.

[0060] It should be pointed out that the connecting rods, the shafts and the connecting rods, and the shafts and the air guide plate 10 can all be connected in a hinged manner.

[0061] like Figure 3 , Fig. 9 and Fig.11As shown, according to some embodiments of the present application, the air guide plate 10 has a fifth connecting rod 11 and a sixth connecting rod 12, and the fifth connecting rod 11 and the sixth connecting rod 12 are respectively arranged on the upper and lower sides and form a first flip center 111 and a second flip center 112 respectively.

[0062] Therefore, by setting the fifth connecting rod 11 and the sixth connecting rod 12, the first flipping center 111 and the second flipping center 112 are both aligned with the plate body of the air guide plate 10, so as to avoid interference between the plate body and surrounding components during the flipping of the air guide plate 10, thereby improving the working stability and reliability of the air guide plate assembly 100.

[0063] Furthermore, the length of the fifth connecting rod 11 is smaller than the length of the sixth connecting rod 12, so that the air guide plate 10 has a larger downward flip angle, further increasing the air supply range and improving the airflow disturbance effect.

[0064] The air conditioner according to the second embodiment of the present application includes: a face frame 200 and the air guide plate assembly 100 in the above embodiment, the power source 40 of the air guide plate assembly 100 is arranged on the face frame 200, and the first input shaft 21 of the first transmission assembly 20 and the second input shaft 31 of the second transmission assembly 30 are connected to the face frame 200.

[0065] According to the air conditioner of the embodiment of the present application, the above-mentioned air guide plate assembly 100 is adopted, so that the air guide plate 10 has a first flip center 111 and a second flip center 112, and the air guide plate 10 can be switched between a first open position and a second open position through a first transmission assembly 20 and a second transmission assembly 30, so that the movement angle of the air guide plate 10 is larger, and large-angle air supply can be achieved, thereby improving the temperature regulation effect and the user experience, and the air sweeping range of the air conditioner can be increased to improve the temperature regulation effect of the air conditioner, and layered temperature regulation of the space where the air conditioner is located can be achieved to improve the comfort.
