[0067] For example, refer to Figure 3 and Figure 4 The above-mentioned air outlet frame 5 may include a first frame body 51 and a second frame body 52, the first frame body 51 and the second frame body 52 are independently formed, the first frame body 51 and the second frame body 52 jointly define an air outlet channel 50, the first frame body 51 and the second frame body 52 are arranged along the front-to-back direction, and the first frame body 51 is located at the front side of the second frame body 52, the driving mechanism 8 can be arranged on the top of the second frame body 52, and the driving mechanism 8 and the air guide structure 7 can be connected in the up-down direction.

[0068] Reference Figure 4 and Figure 5 The driving mechanism 8 includes a driving motor 81 and a transmission member 82. The transmission member 82 is drivably connected between the driving motor 81 and the air guide structure 7. The driving motor 81 can drive the transmission member 82 to move. The movement of the transmission member 82 can drive the air guide structure 7 to move, thereby guiding the airflow in the air outlet channel 50. For example, the driving motor 81 can be a stepping motor.

[0069] Reference Figure 7-Figure 9 The protective shell 9 includes a first protective portion 91, the first protective portion 91 is formed with a guide channel 931, the guide channel 931 extends along a first direction, and the transmission member 82 is movably arranged in the guide channel 931 along the first direction; the inner wall of the guide channel 931 is formed with a first guide structure 932, and the transmission member 82 is formed with a second guide structure 820, the second guide structure 820 cooperates with the first guide structure 932, and the second guide structure 820 is slidable relative to the first guide structure 932 along the first direction.

[0070] For example, the first direction may be an up-down direction, the guide channel 931 extends along the up-down direction, the second guide structure 820 may slide relative to the first guide structure 932 along the first direction, and the transmission member 82 may move along the first direction.

[0071] By cooperating with the first guide structure 932 and the second guide structure 820 sliding along the first direction relative to the first guide structure 932, the transmission member 82 can move along the first direction, so that the transmission member 82 drives the air guide structure 7 to move, thereby guiding the airflow in the air outlet channel 50 to adjust the air outlet direction of the airflow; and, the guide channel 931 cooperates with the transmission member 82, so that the movement of the transmission member 82 is smoother and more stable, and the transmission between the driving mechanism 8 and the air guide mechanism 6 is stable, thereby improving the stability of the movement of the air guide structure 7.

[0072] The above-mentioned air outlet frame assembly 40 can be used in an air conditioner. For example, the air outlet frame assembly 40 can be used in an air conditioning indoor unit 100 of an air conditioner. The air outlet channel 50 of the air outlet frame 5 can be connected to the air outlet 110 of the air conditioning indoor unit 100. The air outlet 110 can be connected to the indoor room. The air guide structure 7 can adjust the air outlet direction of the airflow at the air outlet 110 to realize the airflow outlet toward different areas of the indoor space and adjust the temperature of different areas of the room.

[0073] According to the air outlet frame assembly 40 of the embodiment of the present invention, the second guide structure 820 cooperates with the first guide structure 932 and is slidable along the first direction relative to the first guide structure 932, so that the transmission member 82 can move along the first direction, so that the transmission member 82 drives the air guide structure 7 to move, thereby guiding the airflow in the air outlet channel 50 to adjust the air outlet direction of the airflow; and, the guide channel 931 cooperates with the transmission member 82, so that the movement of the transmission member 82 is smoother and more stable, and the transmission between the driving mechanism 8 and the air guide mechanism 6 is stable, thereby improving the stability of the movement of the air guide structure 7.

[0074] Reference Figure 7-10 According to some embodiments of the present invention, the first protection part 91 includes a first outer shell 92 and an inner guide rail 93, wherein the inner guide rail 93 is disposed in the first outer shell 92 and connected to the first outer shell 92; a guide channel 931 is formed in the inner guide rail 93, and the inner guide rail 93 and the first outer shell 92 are made of different materials. The inner guide rail 93 and the first outer shell 92 are connected to form the first protection part 91, so that the first protection part 91 has a strong structural strength, which can ensure the overall stability of the first protection part 91 and contribute to the smooth operation of the transmission member 82. If the inner guide rail 93 and the first outer shell 92 are made of different materials, there are more materials to choose from for the inner guide rail 93 and the first outer shell 92, which provides flexibility in selection.

[0075] According to some optional embodiments of the present invention, the inner guide rail 93 is a metal member, so that the structural strength of the inner guide rail 93 is relatively strong.

[0076] In some embodiments of the present invention, the inner guide rail 93 is an aluminum part or an aluminum alloy part, which has low cost and light weight.

[0077] According to some optional embodiments of the present invention, the first outer shell 92 is an injection molded part, and the inner guide rail 93 is a stamped part. For example, the inner guide rail 93 is a stamped aluminum alloy part.

[0078] It is understandable that injection molded parts have a demolding angle during production and have a large dimensional tolerance. When the first outer shell 92 is an injection molded part, if the transmission member 82 directly cooperates with the first outer shell 92, there are gaps of varying sizes between the transmission member 82 and the first outer shell 92. In this way, the transmission member 82 is prone to shaking during the movement along the first direction, and the transmission member 82 does not run smoothly, and there are large abnormal noises during operation.

[0079] Since the inner guide rail 93 is a stamped part, there is no problem of demoulding angle during the production of the stamped part, and the dimensional tolerance is small. When the transmission part 82 and the guide channel 931 in the inner guide rail 93 move in coordination, the uniformity of the gap between the transmission part 82 and the inner wall of the inner guide rail 93 can be improved, the smooth operation of the transmission part 82 can be achieved, and the problem of abnormal noise during the operation of the transmission part 82 can be improved.

[0080] Reference Figure 10-12 According to some optional embodiments of the present invention, the inner guide rail 93 and the first outer shell 92 are detachably connected, which facilitates the disassembly and assembly between the inner guide rail 93 and the first outer shell 92. When the first protective portion 91 is damaged or fails during long-term use, it is convenient to replace or maintain the inner guide rail 93, and it is also convenient to replace or maintain the first outer shell 92.

[0081] Reference Fig.10 and Fig.12 In some optional embodiments of the present invention, the inner guide rail 93 and the first outer shell 92 are connected by fasteners, which can ensure the stability of the connection between the inner guide rail 93 and the first outer shell 92, thereby ensuring the stability of the overall structure of the first protective part 91, which helps to improve the service life of the first protective part 91.

[0082] Continue to refer to Fig.10 and Fig.12 In some optional embodiments of the present invention, the first outer shell 92 has a first side wall 921 and a second side wall 923, the first side wall 921 and the second side wall 923 are arranged opposite to each other along the second direction, the fasteners are sequentially arranged through the inner guide rail 93 and the first side wall 921, and an assembly opening 924 is formed on the second side wall 923, the assembly opening 924 is opposite to the fastener, and the assembly opening 924 is used to avoid an operating space for installing the fastener, and the second direction intersects with the first direction. For example, the second direction can refer to the left-right direction in the figure, and the second direction is perpendicular to the first direction.

[0083] The fasteners can be passed through the inner guide rail 93 and the first side wall 921 through the assembly opening 924 , and the operating tools for installing the fasteners can also install the fasteners through the assembly opening 924 , which facilitates the operation and improves the assembly convenience of the inner guide rail 93 .

[0084] For example, refer to Fig.12 According to some specific embodiments of the present invention, a first fixing hole 922 is formed on the first side wall 921 of the first outer shell 92, and a second fixing hole 934 is formed on the side of the inner guide rail 93 facing the first side wall 921, and the second fixing hole 934 corresponds to the first fixing hole 922. The fastener is suitable for passing through the second fixing hole 934 and the first fixing hole 922 to achieve a fixed connection between the inner guide rail 93 and the first outer shell 92.

[0085] Reference Fig.10 and Fig.11 In some optional embodiments of the present invention, the first direction is the up and down direction, and a support limit flange 925 is formed at the bottom of the first outer shell 92. The bottom surface of the inner guide rail 93 is supported by the support limit flange 925. The support limit flange 925 can limit the inner guide rail 93 in the downward direction, which helps to enhance the stability of the inner guide rail 93 installed on the first outer shell 92, and the structure is relatively simple.

[0086] For example, when installing the inner guide rail 93, the inner guide rail 93 can be placed in the first outer shell 92 first, so that the bottom surface of the inner guide rail 93 is supported on the support limit flange 925; then the fastener can be passed through the assembly opening 924 and penetrated into the first side wall 921 of the inner guide rail 93 and the first outer shell 92, thereby fixing the inner guide rail 93 to the first outer shell 92.

[0087] Reference Figure 8 and Fig. 9 According to some embodiments of the present invention, the first guide structure 932 includes a first guide protrusion 933, which extends along the first direction; the second guide structure 820 includes a first guide groove 821, which extends along the first direction, and the first guide protrusion 933 can be slidably accommodated in the first guide groove 821 along the first direction.

[0088] By slidably accommodating the first guide protrusion 933 in the first guide groove 821 along the first direction, the smoothness of the movement of the transmission member 82 in the guide channel 931 can be further enhanced, thereby enhancing the smoothness of the movement of the air guide structure 7 driven by the driving mechanism 8; the first guide protrusion 933 and the first guide groove 821 both extend along the first direction, so that the transmission member 82 has a longer moving distance in the first direction, and the connecting rod 71 has a longer moving distance in the first direction.

[0089] Reference Figure 6 , Figure 7 and Fig.10 According to some embodiments of the present invention, the transmission member 82 is a transmission rack, and the driving mechanism 8 further includes a transmission gear 96, which is disposed on the motor shaft 811 of the driving motor 81, and the transmission gear 96 is meshed with the transmission member 82. When the motor shaft 811 rotates, the transmission gear 96 can be driven to rotate, and the meshing of the transmission gear 96 with the transmission rack can drive the transmission member 82 to move, thereby realizing that the driving mechanism 8 drives the air guide structure 7 to move. The protective shell 9 includes a second protective portion 94, and the second protective portion 94 has a motor cavity 941 connected to the guide channel 931. The driving motor 81 is disposed in the motor cavity 941, so that the overall structure of the driving mechanism 8 is compact, and the space occupied by the driving mechanism 8 is reduced, and the protective shell 9 has a protective effect on the driving motor 81.

[0090] For example, refer to Figure 7 and Fig. 9 According to some specific embodiments of the present invention, the driving motor 81 has two connecting lugs 812, each of which has a first connecting hole 813 formed thereon. Two second connecting holes 942 are provided on the inner wall of the motor cavity 941, and the second connecting holes 942 correspond to the first connecting holes 813 one by one. The driving motor 81 can be connected to the motor cavity 941 by fasteners passing through the second connecting holes 942 and the first connecting holes 813. Two third connecting holes 95 are formed on the protective shell 9, and two fourth connecting holes are formed on the top of the air outlet frame 5, and the fourth connecting holes correspond to the third connecting holes 95 one by one. The fasteners are suitable for passing through the third connecting holes 95 and the fourth connecting holes, so that the protective shell 9 can be connected and fixed to the air outlet frame 5, which is convenient for connection and has strong connection stability. The second protective portion 94 also has a receiving cavity for receiving the transmission gear 96, and the receiving cavity can communicate with the guide channel 931 and the motor cavity 941.

[0091] For example, the assembly process of the above-mentioned driving mechanism 8 is as follows: the transmission gear 96 can be installed in the accommodating cavity first, and then the driving motor 81 can be connected to the motor cavity 941 by fasteners passing through the second connecting hole 942 and the first connecting hole 813; then the inner guide rail 93 can be installed. When installing the inner guide rail 93, the inner guide rail 93 can be first placed in the first outer shell 92 from the upper opening of the first outer shell 92, so that the bottom surface of the inner guide rail 93 is supported on the support limit flange 925, and the fasteners pass through the assembly port 924 and pass through the first side wall 921 of the inner guide rail 93 and the first outer shell 92 to fix the inner guide rail 93 to the first outer shell 92; finally, the transmission member 82 can be placed into the guide channel 931 from the lower connecting port of the guide channel 931, so that the second guide structure 820 cooperates with the first guide structure 932, thereby completing the assembly of the driving mechanism 8.

[0092] Reference Figure 13-Figure 16According to some embodiments of the present invention, the air guide structure 7 includes a connecting rod 71 and a plurality of air guide louvers 72, the plurality of air guide louvers 72 are arranged along a first direction, the connecting rod 71 extends along the first direction, each air guide louver 72 is rotatably connected to the connecting rod 71, and each air guide louver 72 is connected to the air outlet frame 5, and in the first direction, the connecting rod 71 has a driving end 711 and a free end 717 that are relatively arranged, for example, the upper end of the connecting rod 71 is the driving end 711, the lower end of the connecting rod 71 is the free end 717, and the transmission member 82 is connected to the driving end 711. The transmission member 82 can drive the connecting rod 71 to move along the first direction when it moves in the first direction, and the connecting rod 71 can drive the air guide louver 72 to move when it moves, thereby guiding the airflow in the air outlet channel 50 and adjusting the air outlet direction of the airflow.

[0093] Reference Figure 5 , Fig.16 and Fig.17 According to some optional embodiments of the present invention, the transmission member 82 is connected to the driving end 711 through a connecting member 83, and the connecting member 83 includes a first connecting segment 831 and a second connecting segment 832, and the first connecting segment 831 and the second connecting segment 832 are connected to each other and arranged at an angle. The first connecting segment 831 extends along a third direction (for example, the front-to-back direction in the accompanying drawings), and the first connecting segment 831 is connected to the transmission member 82; the second connecting segment 832 extends along the first direction, and the second connecting segment 832 is connected to the driving end 711, and the third direction intersects with the first direction.

[0094] For example, the shape of the connecting member 83 may be L-shaped, the first connecting segment 831 and the second connecting segment 832 are connected to each other at a right angle, the first connecting segment 831 extends in the front-to-back direction, and the second connecting segment 832 extends in the up-down direction.

[0095] The locations of the drive mechanism 8 and the air guide structure 7 are easily limited by space, making it inconvenient for the transmission member 82 to be connected to the connecting rod 71. Therefore, by designing the connecting member 83 to include a first connecting section 831 and a second connecting section 832 extending in different directions, the connecting section is connected to the connecting rod 71, thereby achieving the connection between the transmission member 82 and the connecting rod 71.

[0096] Reference Figure 16-Figure 18In some optional embodiments of the present invention, the air guide louver 72 includes a louver body 720 and a first mounting column 73, and the first mounting column 73 is disposed on the louver body 720; the connecting rod 71 has a first mounting hole 718, and the first mounting column 73 is disposed in the first mounting hole 718 and is rotatable relative to the first mounting hole 718. The central axis of the first mounting hole 718 extends along the second direction, and the first direction, the second direction, and the third direction intersect each other. The center line located in the middle of the second connecting section 832 in the third direction is the first center line e1, and the straight line passing through the center of the first mounting hole 718 and extending along the first direction is the second center line e2. The spacing L1 between the first center line e1 and the second center line e2 in the third direction is less than 12 mm. For example, the spacing L1 between the first center line e1 and the second center line e2 in the third direction is 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0097] The distance L1 between the first center line e1 and the second center line e2 in the third direction can be considered as the power arm of the connecting rod 71. The smaller the power arm, the smaller the torque on the connecting rod 71, and the stronger the reliability of the connecting rod 71. For example, when the first center line e1 and the second center line e2 are located on the same straight line, the transmission member 82 has the best effect in driving the connecting rod 71 to move, and thus the reliability of the connecting rod 71 is the strongest.

[0098] Therefore, by ensuring that the distance L1 between the first center line e1 and the second center line e2 in the third direction is less than 12 mm, the transmission member 82 is connected to the connecting rod 71 and drives the connecting rod 71 to move, while also ensuring that the connecting rod 71 has a smaller lever arm, thereby enhancing the reliability of the connecting rod 71 and ensuring the service life of the connecting rod 71.

[0099] When the transmission member 82 drives the connecting rod 71 to move, the end of the connecting rod 71 close to the transmission member 82 is subjected to the greatest force and is prone to breakage. Therefore, the thickness or width of the end of the connecting rod 71 close to the transmission member 82 can be greater than the thickness or width of the other parts of the connecting rod 71 to enhance its structural strength and increase the service life of the connecting rod 71.

[0100] Reference Figure 5 and Fig.17 In some optional embodiments of the present invention, a connecting rod notch 712 is formed on the side wall of the driving end 711 along the third direction, and the connecting rod notch 712 penetrates two side walls of the driving end 711 that are arranged opposite to each other along the second direction. The wall adjacent to the first connecting section 831 located in the first direction and located at the connecting rod notch 712 is a matching wall 716, and a hanging hole 833 penetrating the second connecting section 832 along the third direction is formed on the second connecting section 832, and the matching wall 716 is penetrated in the hanging hole 833, and a part of the second connecting section 832 is accommodated in the connecting rod notch 712, so that the connecting member 83 can be connected to the driving end 711, and the stability of the connection between the connecting member 83 and the driving end 711 can be enhanced, and the connection operation is convenient.

[0101] Optionally, lubricating oil (such as silicone grease) is provided on the inner wall of the hanging hole 833, so as to reduce the friction noise between the matching wall 716 and the inner wall of the hanging hole 833.

[0102] Reference Fig.16 and Fig.17 In some optional embodiments of the present invention, in the third direction, the connecting rod notch 712 has a guide section 713 and a main section 714 arranged in sequence, a limited step surface 715 is formed between the guide section 713 and the main section 714, and the width of the guide section 713 in the first direction gradually increases in the direction from the main section 714 to the guide section 713. For example, the lower end of the second connecting section 832 is accommodated in the main section 714 of the connecting rod notch 712.

[0103] In the direction from the main section 714 to the guide section 713, the width of the guide section 713 in the first direction gradually increases, and the guide section 713 guides the portion of the second connecting section 832 placed in the connecting rod notch 712, and also guides the matching wall 716 passing through the hanging hole 833, so as to facilitate the connection operation between the second connecting section 832 and the driving end 711. The limiting step surface 715 can limit the matching wall 716, reduce the possibility of the matching wall 716 escaping from the hanging hole 833, and also reduce the possibility of the second connecting section 832 escaping from the connecting rod notch 712, so as to ensure the reliability of the connection between the driving mechanism 8 and the air guide structure 7.

[0104] Reference Fig.17 In some optional embodiments of the present invention, the expansion angle α of the guide segment 713 in the first direction is 15 to 60°, for example, the expansion angle α of the guide segment 713 in the first direction is 38°. By ensuring that the expansion angle α of the guide segment 713 in the first direction is not less than 15°, the expansion angle α of the guide segment 713 in the first direction is prevented from being too small, and the guiding function of the guide segment 713 can be ensured, so that part of the second connecting segment 832 can smoothly pass through the wire segment and enter the main body segment 714, facilitating the connection operation between the second connecting segment 832 and the driving end 711; by ensuring that the expansion angle α of the guide segment 713 in the first direction is not greater than 60°, the expansion angle α of the guide segment 713 in the first direction is prevented from being too large, so as to ensure the limiting function of the limiting step surface 715 on the matching wall 716, and ensure the reliability of the connection between the driving mechanism 8 and the wind guide structure 7.

[0105] Reference Fig.17In some optional embodiments of the present invention, the length L2 of the guide section 713 in the third direction is 2 to 5 mm. For example, the length L2 of the guide section 713 in the third direction is 2.8 mm, 3 mm, 3.5 mm or 4 mm. By having the length L2 of the guide section 713 in the third direction not less than 2 mm, the length of the guide section 713 is prevented from being too small, and the limiting effect of the limiting step surface 715 on the matching wall 716 can be ensured, thereby ensuring the reliability of the connection between the drive mechanism 8 and the air guide structure 7; by having the length L2 of the guide section 713 in the third direction not greater than 5 mm, the length of the guide section 713 is prevented from being too large, causing the drive end 711 to occupy too much space, which is beneficial to improving the compactness of the overall structure of the air guide structure 7.

[0106] Continue to refer to Fig.17 In some optional embodiments of the present invention, the expansion angle α of the guide segment 713 in the first direction is 15 to 60°, and the length L2 of the guide segment 713 in the third direction is 2 to 5 mm.

[0107] By ensuring that the expansion angle α of the guide section 713 in the first direction is not less than 15°, the expansion angle α of the guide section 713 in the first direction is prevented from being too small, thereby ensuring the guiding function of the guide section 713 and facilitating the connection operation between the second connecting section 832 and the driving end 711; by ensuring that the expansion angle α of the guide section 713 in the first direction is not greater than 60°, the expansion angle α of the guide section 713 in the first direction is prevented from being too large, thereby ensuring the limiting function of the limiting step surface 715 on the matching wall 716 and ensuring the reliability of the connection between the driving mechanism 8 and the air guide structure 7.

[0108] By ensuring that the length L2 of the guide section 713 in the third direction is not less than 2 mm, the length of the guide section 713 is prevented from being too small, thereby ensuring the limiting effect of the limiting step surface 715 on the matching wall 716 and ensuring the reliability of the connection between the driving mechanism 8 and the air guide structure 7; by ensuring that the length L2 of the guide section 713 in the third direction is not greater than 5 mm, the length of the guide section 713 is prevented from being too large, causing the driving end 711 to occupy too much space, which is beneficial to improving the compactness of the overall structure of the air guide structure 7.

[0109] Therefore, the expansion angle α of the guide segment 713 in the first direction is 15 to 60°, and the length L2 of the guide segment 713 in the third direction is 2 to 5 mm, so that the guide segment 713 has a suitable expansion angle in the first direction, and the guide segment 713 has a suitable length in the third direction, which can ensure the guiding function of the guide segment 713, facilitate the connection operation between the second connecting segment 832 and the driving end 711, ensure the reliability of the connection between the driving mechanism 8 and the air guide structure 7, and make the overall structure of the air guide structure 7 more compact.

[0110] Reference Figure 13-Figure 15 and Fig. 20 According to some optional embodiments of the present invention, the air guide louver 72 includes a louver body 720 and a second mounting column 74, and the second mounting column 74 is disposed on the louver body 720; the air outlet frame 5 has a second mounting hole 511, for example, the second mounting hole 511 can be formed in the first frame body 51, the second mounting column 74 is passed through the second mounting hole 511, and the second mounting column 74 is fixed relative to the second mounting hole 511. The louver body 720 is a flexible louver, and the louver body 720 includes a fixed area 721 and a movable area 722, wherein the second mounting column 74 is disposed in the fixed area 721, and the rigidity of the fixed area 721 is greater than the rigidity of the movable area 722.

[0111] The movable area 722 has a lower rigidity and is easily deformed when subjected to force; the fixed area 721 has a higher rigidity and is not easily deformed when subjected to force, and the second mounting column 74 is disposed in the fixed area 721, and the second mounting column 74 is fixed relative to the second mounting hole 511, and the fixed area 721 is fixed relative to the second mounting hole 511.

[0112] When the transmission member 82 drives the connecting rod 71 to move, the connecting rod 71 can drive the active area 722 of the louver body 720 to move; since the fixed area 721 is fixed relative to the second mounting hole 511, the active area 722 can bend and deform to form a curved surface, which can adjust the flow direction of the airflow in the air outlet channel 50, and the curved surface has a better wind guiding effect, which can increase the air supply range.

[0113] For example, when the air outlet frame assembly 40 is used in an air conditioner, after the active area 722 of the louver body 720 is bent to form a curved surface, the curved surface guides the air flow in the air outlet channel 50, which can increase the air supply angle of the air outlet 110 of the air conditioner, thereby increasing the coverage range of the air flow, so that the air flow can quickly exchange heat with the indoor air, so as to achieve the purpose of quickly adjusting the indoor temperature and improving the comfort of different areas in the room.

[0114] The first direction may be an up-down direction, and the transmission member 82 may drive the connecting rod 71 to move in the up-down direction. For example, when the air conditioner is cooling, the driving mechanism 8 may drive the connecting rod 71 to move upward, and the movable area 722 may be bent and deformed upward, so that the shutter body 720 may guide the airflow in the air outlet channel 50 upward, so that the angle of the air outlet 110 to discharge upward is increased; while the cold air tends to sink, and the cold air blown upward may diffuse downward and far away, so that the air supply distance may be increased, and the airflow coverage area may be increased, so that the cold air may be quickly mixed with the indoor air, so that rapid cooling may be achieved. For another example, when the air conditioner is heating, the driving mechanism 8 may drive the connecting rod 71 to move downward, and the movable area 722 may be bent and deformed downward, so that the shutter body 720 may guide the airflow in the air outlet channel 50 downward, so that the angle of the air outlet 110 to discharge downward is increased; while the hot air tends to float upward, and the cold air blown downward may diffuse upward and far away, so that the air supply distance may be increased, and the airflow coverage area may be increased, so that the hot air may be quickly mixed with the indoor air, so that rapid heating may be achieved.

[0115] The active area 722 accounts for more than 90% of the area of ​​the louver body 720, so that the area of ​​the louver body 720 that can be deformed by force is larger, ensuring that the area of ​​the curved surface for guiding wind formed after the louver body 720 is deformed is larger, further improving the wind guiding effect of the wind guiding louver 72. For example, the active area 722 accounts for 94%, 95% or 96% of the area of ​​the louver body 720.

[0116] Reference Fig. 22 The active area 722 includes alternately arranged first louver portions 723 and second louver portions 724, and the thickness of the first louver portions 723 and the second louver portions 724 are different. For example, the thickness of the first louver portion 723 is larger, and the thickness of the second louver portion 724 is smaller; or, the thickness of the first louver portion 723 is smaller, and the thickness of the second louver portion 724 is larger.

[0117] The first louver portion 723 and the second louver portion 724 have different thicknesses, which can ensure the structural strength of the active area 722 while also ensuring the flexibility of the active area 722 , ensuring that the active area 722 can bend and deform under the drive of the transmission member 82 to enhance the wind guiding effect of the wind guide louver 72 .

[0118] Reference Fig. 22 In some optional embodiments of the present invention, the thickness of the first louver portion 723 is 0.3-0.4 mm, and the thickness of the second louver portion 724 is 0.5-0.6 mm. For example, the thickness of the first louver portion 723 may be 0.3 mm, 0.35 mm, or 0.4 mm, and the thickness of the second louver portion 724 may be 0.5 mm, 0.55 mm, or 0.6 mm.

[0119] The thickness of the first louver portion 723 is 0.3-0.4 mm, and the thickness of the second louver portion 724 is 0.5-0.6 mm, so as to ensure the flexibility of the active area 722 and ensure that the active area 722 can bend and deform under the drive of the transmission member 82 to enhance the wind guiding effect of the wind guide louver 72; the structural strength of the active area 722 can also be ensured.

When the transmission member 82 drives the connecting rod 71 to move, the louver body 720 can be bent and deformed to form a curved surface, the curved surface can adjust the flow direction of the airflow in the air outlet channel 50, and the curved surface has a better wind guiding effect, which can increase the air supply range.

[0121] Reference Fig.13 and Fig. 22 A limiting protrusion 741 is formed on the outer peripheral wall of the second mounting column 74, and a limiting groove 512 connected to the second mounting hole 511 is formed on the inner wall of the air outlet channel 50. The limiting protrusion 741 is accommodated in the limiting groove 512, which can reduce the risk of rotation of the second mounting column 74 and ensure that the second mounting column 74 is fixed relative to the second mounting hole 511, thereby better realizing the wind guiding effect of the louver body 720.

[0123] Among them, the inner wall of the elastic notch 743 is formed with a reinforcing rib 744, which can enhance the stability of the elastic notch 743, prevent the elastic notch 743 from easily deforming or collapsing and causing the second mounting column 74 to fall out of the second mounting hole 511, and ensure the stability of the air guide louver 72 installed on the air outlet frame 5.

[0124] Reference Fig.21In some optional embodiments of the present invention, at least a portion of the outer end surface 742 is formed as a guide slope 745. In the radially outward direction from the second mounting column 74, the guide slope 745 extends obliquely toward the direction adjacent to the shutter body 720, and the inclination angle β of the guide slope 745 is 45 to 60°. For example, the inclination angle β of the guide slope 745 can be 45°, 47°, 50° or 60°.

[0125] At least a portion of the outer end surface 742 is formed as the guide slope 745 , which may include the following situations: a portion of the outer end surface 742 is formed as the guide slope 745 ; the outer end surface 742 is formed as the guide slope 745 .

[0126] The guide slope 745 extends obliquely toward the direction adjacent to the louver body 720, and the guide slope 745 guides the installation of the second mounting column 74 in the second mounting hole 511, thereby improving the convenience of assembling the air guide louver 72 on the air outlet frame 5. The guide slope 745 has an inclination angle β of not more than 60°, which can ensure the guiding function of the guide slope 745 and prevent the second mounting column 74 from easily falling out of the second mounting hole 511; the guide slope 745 has an inclination angle β of not less than 45°, which can better guide the second mounting column 74 to pass through the second mounting hole 511, thereby further improving the convenience of assembling the air guide louver 72 on the air outlet frame 5.

[0127] For example, refer to Fig.21 According to some specific embodiments of the invention, two spring buckles 746 are provided on opposite sides of the elastic notch 743 in the radial direction. The spring buckles 746 can serve as the inner wall of the elastic notch 743, and a reinforcing rib 744 is formed at one end of the spring buckle 746 away from the louver body 720. When the guide slope 745 guides the second mounting post 74 to be installed in the second mounting hole 511, the two spring buckles 746 approach each other; when the second mounting post 74 is installed in the second mounting hole 511, the spring buckles 746 move away from each other under their own elastic action, and one end of the two spring buckles 746 adjacent to the louver body 720 is connected by the connecting rib 747, which can enhance the structural strength of the spring buckle 746 and ensure the stability of the second mounting post 74 and the second mounting hole 511.
