Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0058] The louver assembly 10 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0059] like Figure 1 , Figure 2 and Figures 12-23 As shown, the louver assembly 10 according to an embodiment of the present invention includes: a connecting rod 1, a plurality of louvers 2 and a louver drive component 73.

[0060] Specifically, if Figure 1 , Figure 2 and Figures 12-20 As shown, the louver assembly 10 is used in the air outlet frame assembly 100, which has an air outlet 202. The connecting rod 1 extends along the length direction of the air outlet 202 (e.g., the up-down direction in this utility model), and one end of the connecting rod 1 has a closed locking hole 11. Multiple louvers 2 are spaced apart along the length direction of the air outlet 202 and are all rotatably connected to the connecting rod 1. The louver drive member 73 is located on one side of the length direction of the air outlet 202. The louver drive member 73 has a rack 31 that moves along the length direction of the air outlet 202. The rack 31 has a hook portion 311 that cooperates with the locking hole 11. The extension direction of the locking hole 11 is perpendicular to the length direction of the connecting rod 1, and the hook portion 311 is movably located in the locking hole 11.

[0061] It should be noted that multiple louvers 2 are spaced apart along the length of the air outlet 202 and are all rotatably connected to the connecting rod 1, so that the rack 31 drives the connecting rod 1 to move along the length of the air outlet 202, thereby driving the multiple louvers 2 to rotate. At the same time, the connecting rod 1 moves along the extension direction of the locking hole 11 to realize the air guiding of the louver assembly 10.

[0062] Understandably, by providing a closed locking hole 11 at one end of the connecting rod 1, the structure at the connection point between the connecting rod 1 and the rack 31 becomes stable, less prone to deformation, and possesses good rigidity, thus better supporting the movement of the connecting rod 1 and making its movement more stable and smooth. The extension direction of the hook portion 311 is perpendicular to the extension direction of the rack 31. Since the rack 31 has a relatively small length along the length of the air outlet 202 and its own high rigidity, the notch-type hook portion 311 is not prone to deformation, ensuring the stability and smoothness of the connecting rod 1 during movement.

[0063] Furthermore, such as Figure 1 As shown, the louver drive component 73 also includes a drive motor, which is used to drive the rack 31 to move along the length of the air outlet 202. The drive shaft of the drive motor is connected to the rack 31 through a worm gear, thereby enabling the drive motor to drive the rack 31 to move along the length of the air outlet 202.

[0064] In addition, since the rack 31 and the connecting rod 1 are engaged by the hook part 311 and the locking hole 11, compared with the rack 31 and the connecting rod 1 being connected by fasteners, there is no need to tighten the fasteners, which ensures the ease of installation between the rack 31 and the connecting rod 1 and improves the efficiency of disassembly and assembly.

[0065] According to the embodiment of the present invention, the louver assembly 10 extends along the length direction of the air outlet 202 via a connecting rod 1, and a closed locking hole 11 is provided at one end of the connecting rod 1; a hook portion 311 that cooperates with the locking hole 11 is provided on the rack 31 of the louver drive component 73. The extension direction of the locking hole 11 is perpendicular to the length direction of the connecting rod 1, and the hook portion 311 is movably provided in the locking hole 11, thereby making the structure of the connection between the connecting rod 1 and the rack 31 stable, not easily deformed, and having good rigidity, which can better support the movement of the connecting rod 1, making the connecting rod 1 more stable and smooth when moving.

[0066] In some embodiments of this utility model, such as Figures 12-16 As shown, the hook portion 311 has a mating rib 312 on at least one side along the length of the connecting rod 1, and the mating rib 312 extends along the axial direction of the locking hole 11. For example, in this utility model, the hook portion 311 has mating ribs 312 on both sides along the length of the connecting rod 1, but this utility model is not limited to this, and the hook portion 311 may also have a mating rib 312 on one side along the length of the connecting rod 1.

[0067] It is understandable that the mating rib 312 is suitable for contacting the hole wall of the locking hole 11. By setting the mating rib 312, the large surface of the hook part 311 along the length direction of the connecting rod 1 with the mating rib 312 is prevented from directly contacting the hole wall of the locking hole 11, thereby reducing the contact area between the hook part 311 and the hole wall of the locking hole 11, reducing the friction force of the connecting rod 1 when moving, and making the connecting rod 1 more stable and smooth when moving.

[0068] In some embodiments of this utility model, such as Figures 12-16 As shown, the mating ribs 312 on one side of the hook portion 311 along the length of the connecting rod 1 are multiple and spaced apart along the length of the locking hole 11. This avoids direct contact between the large surface of the hook portion 311 with the mating ribs 312 along the length of the connecting rod 1 and the wall of the locking hole 11, reducing the contact area between the hook portion 311 and the wall of the locking hole 11, thus reducing the friction force of the connecting rod 1 during movement and making the connecting rod 1 move more stably and smoothly. Furthermore, it increases the support of the wall of the locking hole 11 for the hook portion 311, making the connecting rod 1 more stable and reliable during movement.

[0069] For example, Figures 12-15 In the example shown, the mating ribs 312 on one side of the hook portion 311 along the length direction of the connecting rod 1 are two spaced apart along the length direction of the locking hole 11. However, the present invention is not limited to this. The mating ribs 312 on one side of the hook portion 311 along the length direction of the connecting rod 1 are more than one spaced apart along the length direction of the locking hole 11, such as 3, 4, 5 or 6.

[0070] In some embodiments of this utility model, such as Figure 19 and Figure 20 As shown, the inner peripheral wall of the retaining hole 11 has a parting line 111, and the mating ribs 312 are spaced apart from the parting line 111 in the axial direction of the retaining hole 11. It should be noted that the parting line 111 refers to the boundary line where two or more parts of the mold separate when the mold is opened and closed. During injection molding, the parting line 111 is the location where mold components mate, and it is also the mold seam mark visible on the product. At the same time, the parting line 111 often has burrs. Burrs are excess, useless parts that appear at the edge of the product due to material flowability, mold structure defects, inappropriate molding processes, etc., during injection molding or mold forming. These excess parts usually appear as rough edges, flash, or overflow, which can not only cause injury to the user but also affect the appearance and performance of the product.

[0071] Understandably, the mating rib 312 and the parting line 111 are spaced apart in the axial direction of the locking hole 11, thereby avoiding the burrs on the parting line 111 from interfering with the movement of the mating rib 312 within the length range of the locking hole 11. This makes the connecting rod 1 more stable and smooth when moving. At the same time, it also avoids the burrs on the parting line 111 from affecting the installation of the rack 31 and the connecting rod 1, so that the rack 31 and the connecting rod 1 can be installed smoothly.

[0072] In some embodiments of this utility model, such as Figures 12-17 As shown, the hook portion 311 has a limiting protrusion 313 on at least one side along the length direction of the connecting rod 1. The limiting protrusion 313 is located at one end of the hook portion 311 along the length direction of the locking hole 11. The connecting rod 1 has at least one limiting hole 12 that cooperates with the limiting protrusion 313. The limiting hole 12 penetrates the connecting rod 1 along the axial direction of the locking hole 11 and communicates with the locking hole 11. The limiting hole 12 is located at one end of the length direction of the locking hole 11.

[0073] Understandably, when it is necessary to install connecting rod 1 and rack 31, the limiting protrusion 313 can be aligned with the limiting hole 12, allowing the hook part 311 to smoothly enter the locking hole 11, completing the installation between connecting rod 1 and rack 31. Simultaneously, the mutual cooperation between the limiting protrusion 313 and the limiting hole 12 provides a foolproof design for the installation between connecting rod 1 and rack 31, thus facilitating the installation and improving installation efficiency. Furthermore, when connecting rod 1 moves along the length of locking hole 11, the limiting protrusion 313 prevents the hook part 311 from disengaging from locking hole 11 along its axial direction.

[0074] For example, in this utility model, the hook portion 311 has a limiting protrusion 313 at one end along the length direction of the connecting rod 1, and the connecting rod 1 has a limiting hole 12 that cooperates with the limiting protrusion 313. However, this utility model is not limited to this. It is also possible that the hook portion 311 has a limiting protrusion 313 at both ends along the length direction of the connecting rod 1, and the connecting rod 1 has two limiting holes 12 that cooperate with the two limiting protrusions 313 respectively.

[0075] In some embodiments of this utility model, such as Figures 16-20 As shown, along the direction in which the hook portion 311 is inserted into the locking hole 11, the two inner walls of the locking hole 11, which are opposite each other along the length of the connecting rod 1, extend at an incline towards each other. It is understood that the connecting rod 1 is injection molded, and after the injection-molded connecting rod 1 cools, it may adhere tightly to the inner wall of the mold due to plastic shrinkage. If the hole wall of the locking hole 11 is horizontal, the product is easily scratched or the hole wall is damaged during demolding. The inclined hole wall reduces the friction between the connecting rod 1 and the mold, helping the connecting rod 1 to disengage more easily from the mold.

[0076] In some embodiments of this utility model, such as Figures 16-20 As shown, the angles between the two opposing inner walls of the retaining hole 11 along the length of the connecting rod 1 and the axis of the retaining hole 11 are all between 0.5° and 15°, such as 0.5°, 1°, 3°, or 15°. This reduces friction between the product and the mold, making it easier for the connecting rod 1 to disengage from the mold. It also prevents the angles between the two opposing inner walls of the retaining hole 11 along the length of the connecting rod 1 and the axis of the retaining hole 11 from being too large, which could affect the stability of the connecting rod 1 during movement, resulting in smoother and more stable movement of the connecting rod 1.

[0077] In some embodiments of this utility model, such as Figures 16-20 As shown, the connecting rod 1 includes: a first connecting part 13, a second connecting part 14 and a third connecting part 15, with a locking hole 11 provided on the first connecting part 13; the second connecting part 14 and the first connecting part 13 are spaced apart along the length of the air outlet 202, and the louver 2 is rotatably provided on the second connecting part 14; the two ends of the third connecting part 15 along the length of the air outlet 202 are respectively connected to the first connecting part 13 and the second connecting part 14, and there is an angle between the third connecting part 15 and the length of the air outlet 202.

[0078] It is understandable that there is an angle between the third connecting part 15 and the air outlet 202 along their length direction, so that the first connecting part 13 and the second connecting part 14 can be staggered in the axial direction of the card hole 11, which facilitates the connection of the first connecting part 13 with the hook part 311 and also facilitates the connection of the second connecting part 14 with the louver 2.

[0079] In some embodiments of this utility model, such as Figures 16-20 As shown, along the axial direction of the locking hole 11, the distance between the midpoint of the first connecting part 13 and the midpoint of the second connecting part 14 is less than 15mm, for example, 3mm, 5mm, 10mm or 14mm. This avoids excessive spacing between the first connecting part 13 and the second connecting part 14 along the axial direction of the locking hole 11, thereby ensuring the overall stability of the connecting rod 1 and reducing the likelihood of vibration in the connecting rod 1.

[0080] In some embodiments of this utility model, such as Figure 3 and Figure 23 As shown, along the airflow direction, the two walls of the connecting rod 1 at the windward end, extending in the width direction of the air outlet 202, extend in an inclined direction away from each other. This reduces the obstruction of the airflow by the windward end of the connecting rod 1, making the airflow smoother.

[0081] The air outlet frame assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0082] like Figures 1-11As shown, the air outlet frame assembly 100 according to an embodiment of the present utility model includes: an air outlet frame 20 and the above-mentioned louver assembly 10.

[0083] Specifically, refer to Figures 1-11 As shown, the air outlet frame 20 has an air outlet duct 201 and an air outlet 202 communicating with the air outlet duct 201; louvers 2 and connecting rod 1 are disposed within the air outlet duct 201, and louver drive component 73 is disposed on the air outlet frame 20. The louvers 2 and connecting rod 1 are disposed in the air outlet duct 201 to facilitate adjustment of the airflow direction to the air outlet 202, and the louver drive component 73 is disposed on the air outlet frame 20 to facilitate the fixing and installation of the louver drive component 73.

[0084] Furthermore, such as Figures 1-11 As shown, the louvers 2 are engaged with the air inlet end of the air outlet frame 20. It should be noted that the airflow enters the air outlet duct 201 from the air inlet end of the air outlet frame 20, and then is guided by multiple louvers 2, so that the airflow can flow out from the air outlet 202, thus achieving the airflow guiding function.

[0085] Understandably, because the louver 2 is snapped into the air inlet end of the air outlet frame 20, the louver 2 can be connected and installed with the air outlet frame 20 in the direction of airflow, thus avoiding the installation of the louver 2 in the width direction of the air outlet 202. At the same time, the air inlet end of the air outlet frame 20 is unobstructed, which makes the installation of the louver 2 and the air outlet frame 20 convenient, improves the installation efficiency and installation quality, and reduces the problem of parts being damaged due to improper installation.

[0086] In some embodiments of this utility model, such as Figures 2-4 As shown, the air outlet frame 20 has a first sidewall 203 forming an air outlet duct 201. The first sidewall 203 is located on one side of the air outlet duct 201 in the width direction. The louver 2 includes a body portion 21 and a snap-fit ​​portion 22. The snap-fit ​​portion 22 is provided on one side of the body portion 21 along the width direction of the air outlet duct 201, and the snap-fit ​​portion 22 is snap-fitted to the air inlet end of the first sidewall 203. It can be understood that the body portion 21 is rotatably mounted on the connecting rod 1, and the snap-fit ​​portion 22 is provided on the side of the body portion 21 facing the first sidewall 203 along the width direction of the air outlet duct 201, thereby facilitating the snap-fit ​​portion 22 to snap-fit ​​to the air inlet end of the first sidewall 203.

[0087] In some embodiments of this utility model, such as Figures 2-6 As shown, the snap-fit ​​part 22 has a slot 221 with an opening facing the air outlet 202. The air inlet end of the first side wall 203 is snapped into the slot 221. The part of the snap-fit ​​part 22 located on the side of the slot 221 away from the air outlet duct 201 is formed as a snap-fit ​​part 222.

[0088] Understandably, the opening of the slot 221 faces the air outlet 202, facilitating the entry of the air inlet end of the first side wall 203, and thus enabling the engaging part 22 to engage with the air inlet end of the first side wall 203 along the airflow direction. Simultaneously, the bottom wall 2211 of the slot can abut against the air inlet end of the first side wall 203, thereby restricting the movement of the engaging part 22 and the first side wall 203 relative to each other along the airflow direction, improving the installation reliability and stability between the louver 2 and the air outlet frame 20.

[0089] In some embodiments of this utility model, such as Figures 4-11 As shown, the end of the latching part 222 facing the air outlet 202 along the airflow direction has a limiting hook 223 extending towards the air outlet duct 201, and the side of the first sidewall 203 facing away from the air outlet duct 201 has a limiting groove 204 that cooperates with the limiting hook 223. It can be understood that the cooperation between the limiting groove 204 and the limiting hook 223 can restrict the latching part 22 and the first sidewall 203 from moving away from each other along the airflow direction, thereby improving the installation reliability and stability between the louver 2 and the air outlet frame 20.

[0090] Furthermore, such as Figures 4-11 As shown, the side of the first sidewall 203 facing away from the air outlet duct 201 has a mounting groove 207. At least a portion of the snap-fit ​​part 222 is disposed in the mounting groove 207. The inner peripheral wall of the mounting groove 207 can restrict the snap-fit ​​part 222 from moving along the length direction of the air outlet frame 20, thereby further improving the installation reliability and stability between the louver 2 and the air outlet frame 20. The mounting groove 207 has a limiting rib extending along the length direction of the air outlet frame 20, dividing the mounting groove 207 into two slots spaced apart along the airflow direction. The slot near the air outlet 202 is a limiting groove 204. The snap-fit ​​part 222 is adapted to be disposed in the limiting groove 204 and abut against the limiting rib, thereby restricting the snap-fit ​​part 22 and the first sidewall 203 from moving away from each other along the airflow direction, improving the installation reliability and stability between the louver 2 and the air outlet frame 20.

[0091] In some embodiments of this utility model, such as Figures 2-4 As shown, the latching part 22 also has a first notch 224 opening towards the air outlet 202. The first notch 224 is spaced apart from the latching groove 221 and located within the air outlet duct 201. Therefore, the first notch 224 prevents the main body 21 from affecting the latching part 22 during rotation, thus preventing the latching part 22 from rotating. This reduces the risk of relative rotation between the latching part 22 and the first sidewall 203 during louver 2 rotation, thereby reducing damage to the latching part 22 and / or the first sidewall 203 and improving the structural durability.

[0092] In some embodiments of this utility model, such as Figures 2-11As shown, the air inlet end of the first sidewall 203 has a second notch 205, and the bottom wall 2211 of the slot is located within the second notch 205. It can be understood that the bottom wall 2211 of the slot is located within the second notch 205, so that at least a portion of the engaging part 22 is disposed within the second notch 205. The second notch 205 facilitates, on the one hand, the engaging part 22 extending into the second notch 205 and engaging with the first sidewall 203. On the other hand, the second notch 205 allows the two walls of the second notch 205 along the length of the air outlet frame 20 to limit the engaging part 22, thereby preventing the engaging part 22 from moving along the length of the air outlet frame 20, and improving the installation reliability and stability between the louver 2 and the air outlet frame 20.

[0093] In some embodiments of this utility model, such as Figure 5 , Figure 6 and Figure 22 As shown, the snap-fit ​​portion 22 has a first positioning protrusion 225 on at least one side along the length direction of the air outlet 202, and the first positioning protrusion 225 is adapted to abut against the side wall of the second notch 205. For example, in this utility model, the snap-fit ​​portion 22 has the first positioning protrusion 225 on both sides along the length direction of the air outlet 202, but this utility model is not limited to this, and the snap-fit ​​portion 22 may also have the first positioning protrusion 225 on one side along the length direction of the air outlet 202.

[0094] Understandably, the design of the first positioning protrusion 225 increases the length of the locking part 22 along the length of the air outlet 202, thereby facilitating its contact with the side wall of the second notch 205. This prevents the locking part 22 from moving along the length of the air outlet frame 20, improving the installation reliability and stability between the louver 2 and the air outlet frame 20. Simultaneously, the smaller contact area between the first positioning protrusion 225 and the side wall of the second notch 205 results in less friction and less installation resistance, facilitating the connection between the louver 2 and the air outlet frame 20 and making the installation of the louver 2 and the air outlet frame 20 smoother.

[0095] Furthermore, the sidewalls of the first positioning protrusion 225 and the second notch 205 are interference-fitted. The first positioning protrusion 225 is deformable, thereby further improving the connection reliability between the snap-fit ​​part 22 and the first sidewall 203. At the same time, the deformation of the first positioning protrusion 225 can absorb and adaptively adjust the tolerance between the snap-fit ​​part 22 and the first sidewall 203, thereby facilitating the connection and installation between the snap-fit ​​part 22 and the first sidewall 203.

[0096] In some embodiments of this utility model, such as Figure 5 , Figure 6 and Figure 22As shown, the first positioning protrusion 225 on one side of the snap-fit ​​part 22 along the length direction of the air outlet 202 is a plurality of spaced-apart protrusions. This further increases the reliability of the side wall stop between the snap-fit ​​part 22 and the second notch 205, thereby further preventing the snap-fit ​​part 22 from moving along the length direction of the air outlet frame 20, and improving the installation reliability and stability between the louver 2 and the air outlet frame 20.

[0097] For example, Figure 5 , Figure 6 and Figure 22 In the example shown, there are two first positioning protrusions 225 on one side of the snap-fit ​​part 22 along the length direction of the air outlet 202. However, the present invention is not limited to this. There can be more first positioning protrusions 225 on one side of the snap-fit ​​part 22 along the length direction of the air outlet 202, such as 3, 4, 5 or 6.

[0098] In some embodiments of this utility model, such as Figures 2-4 and Figure 11 As shown, the side of the first sidewall 203 facing away from the air outlet duct 201 has a second positioning protrusion 206, which is adapted to abut against the latching part 222. It can be understood that the second positioning protrusion 206 abuts against the side of the latching part 222 facing the air outlet duct 201, thereby restricting the movement of the latching part 222 towards the air outlet duct 201, further improving the installation reliability and stability between the louver 2 and the air outlet frame 20.

[0099] Furthermore, such as Figures 4-11 As shown, the side of the first sidewall 203 away from the air outlet duct 201 has a mounting groove 207, at least a portion of the snap fastener 222 is provided in the mounting groove 207, and the second positioning protrusion 206 is provided on the inner peripheral wall of the mounting groove 207 and extends obliquely in the direction away from the bottom wall of the mounting groove 207.

[0100] In some embodiments of this utility model, such as Figure 11 As shown, the second positioning protrusions 206 are multiple spaced apart. This further restricts the movement of the latching part 222 toward the air outlet duct 201, further improving the installation reliability and stability between the louver 2 and the air outlet frame 20.

[0101] For example, Figure 11 In the example shown, there are two second positioning protrusions 206, but the present invention is not limited to this. There can also be multiple second positioning protrusions 206, such as 3, 4, 5 or 6.

[0102] In some embodiments of this utility model, such as Figure 5 and Figure 6As shown, the side of the latching part 222 facing away from the air outlet duct 201 has a reinforcing rib 226. This improves the structural strength of the latching part 222 and enhances the durability of the louver 2.

[0103] In some embodiments of this utility model, such as Figures 2-4 and Figure 23 As shown, along the airflow direction, the main body 21 includes a first section 211, a second section 212 and a third section 213 connected in sequence. The third section 213 is rotatably connected to the connecting rod 1. The first section 211 is connected to the snap-fit ​​part 22. The second section 212 is a flexible part.

[0104] It is understandable that when the connecting rod 1 moves along the length of the air outlet 202, it will drive the third section 213 to rotate. The third section 213 has the tendency to drive the second section 212 to rotate. Since the first section 211 is connected to the snap-fit ​​part 22 and the first section 211 is a rigid part, the second section 212 will deform. Thus, through the rotation of the first section 211 and the deformation of the second section 212, the airflow can change its direction, achieving the effect of guiding air in different directions.

[0105] Meanwhile, since the second segment 212 deforms, the first segment 211 does not need to rotate, thereby avoiding relative rotation between the snap-fit ​​part 22 and the first side wall 203. This reduces the risk of damage to the snap-fit ​​part 22 and / or the first side wall 203 caused by relative rotation between the snap-fit ​​part 22 and the first side wall 203 when the louver 2 rotates, thus improving the durability of the structure.

[0106] In some embodiments of this utility model, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the air outlets 202 are multiple and spaced apart along the width of the air outlet frame 20, and the louver assemblies 10 are multiple corresponding to each other. This improves the air outlet efficiency and the working efficiency of the air conditioner 1000.

[0107] For example, Figure 1 , Figure 2 , Figure 7 and Figure 8 In the example shown, there are two air outlets 202 spaced apart along the width of the air outlet frame 20. However, this utility model is not limited to this. There can be more air outlets 202, such as 3, 4, 5 or 6.

[0108] The following description refers to an air conditioner 1000 according to an embodiment of the present invention.

[0109] The air conditioner 1000 according to an embodiment of the present utility model includes the above-described air outlet frame assembly 100.

[0110] According to the embodiment of the present utility model, the air conditioner 1000 includes the above-mentioned air outlet frame assembly 100 and louver assembly 10. The connecting rod 1 extends along the length direction of the air outlet 202, and a closed locking hole 11 is provided at one end of the connecting rod 1. A hook portion 311 that cooperates with the locking hole 11 is provided on the rack 31 of the louver drive component 73. The extension direction of the locking hole 11 is perpendicular to the length direction of the connecting rod 1. The hook portion 311 is movably provided in the locking hole 11, thereby making the structure of the connection between the connecting rod 1 and the rack 31 stable, not easily deformed, and having good rigidity. It can better support the movement of the connecting rod 1, making the connecting rod 1 more stable and smooth when moving.
