Description

Technical Field

[0002] Air conditioners have air deflectors and louvers installed at their air outlets. Both are crucial components for adjusting the direction of airflow. In related technologies, multiple louvers are driven to swing together via a connecting rod. A drive motor is located at one end of the connecting rod along its length, causing the connecting rod to move along the length of the rod, thus pulling the multiple louvers to rotate synchronously. However, when the drive motor pulls the connecting rod, the rod is prone to bending due to the resistance of the louvers, preventing the connecting rod from reliably and effectively pulling the louvers to rotate.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0030] The air guide component 100 of the first aspect of this utility model is described below with reference to the accompanying drawings.

[0031] According to the embodiment of the present utility model, the air guide component 100, such as Figure 1 and Figure 2 As shown, the air guiding component 100 includes: an air guiding plate 1, louvers 2, a connecting rod 3, a drive mechanism 4, and a connector 5. Multiple louvers 2 are arranged at intervals along the length X of the air guiding plate 1, and each louver 2 is rotatably connected to the air guiding plate 1. The connecting rod 3 extends along the length X of the air guiding plate 1 and is rotatably connected to each louver 2. The drive mechanism 4 is located at one end of the connecting rod 3 along its length and is connected to the connecting rod 3 to drive the louvers 2 to rotate relative to the air guiding plate 1 by pulling the connecting rod 3. The connector 5 is located between the louver 2 closest to the drive mechanism 4 and the drive mechanism 4, and is rotatably connected to the air guiding plate 1 and the connecting rod 3. The drive mechanism 4 pulls the connector 5 to rotate in the same direction as the louvers 2 via the connecting rod 3.

[0032] Therefore, according to the embodiment of the present utility model, the air guide component 100, by providing a connecting member 5 between the louver 2 closest to the drive mechanism 4 and the drive mechanism 4, and the connecting member 5 being pulled by the connecting rod 3 and rotating in the same direction as the louver 2, can effectively reduce the risk of the connecting rod 3 bending due to the resistance of the louver 2 when the drive mechanism 4 drives the connecting rod 3, thereby enabling the connecting rod 3 to reliably and effectively drive the louver 2 to rotate under the driving action of the drive mechanism 4.

[0033] The air guide plate 1 is the main body of the air guide component 100. The air guide plate 1 can guide the airflow. The air guide component 100 also includes a plurality of louvers 2 spaced apart along the length direction X of the air guide plate 1. Each louver 2 is rotatably connected to the air guide plate 1. The louver 2 can rotate to guide the air. By arranging the louvers 2 along the length direction X of the air guide plate 1, the air guide plate 1 and the louvers 2 can guide the air in different directions, thereby increasing the air guiding range of the air guide component 100.

[0034] For example, the length direction X of the air guide plate 1 is the left-right direction, and the air guide plate 1 can guide the airflow in the up-down direction or in the front-back direction; multiple louvers 2 are arranged at intervals along the left-right direction, and the louvers 2 can swing left and right to guide the airflow in the left-right direction, which has a large guiding range for the airflow and can improve the air guiding effect of the air guiding component 100. In actual use, the length direction X of the air guide plate 1 can be arranged in the vertical direction or in the horizontal direction, and this application does not impose any restrictions.

[0035] The air guiding component 100 also includes a connecting rod 3. The extension direction (or length direction) of the connecting rod 3 is consistent with the arrangement direction of the louvers 2. The connecting rod 3 also extends along the length direction X of the air guiding plate 1. The connecting rod 3 is rotatably connected to each louver 2, and the connecting rod 3 can drive the louvers 2 to rotate relative to the air guiding plate 1. The air guiding component 100 also includes a drive mechanism 4, which is connected to the connecting rod 3. The drive mechanism 4 pulls the connecting rod 3 to drive multiple louvers 2 to rotate relative to the air guiding plate 1. By setting the connecting rod 3, multiple louvers 2 can be driven to rotate relative to the air guiding plate 1 simultaneously, which can improve the overall movement of multiple louvers 2, improve the air guiding effect, and only one drive mechanism 4 is needed to drive multiple louvers 2 simultaneously, reducing costs and requiring less space for arrangement.

[0036] Furthermore, the drive mechanism 4 is located at one end of the connecting rod 3 along its length, that is, on the X side of the length direction of the air guide plate 1. This reduces the space occupied by the air guide plate 1 in both the width and thickness directions. It can be understood that when airflow passes through the air guide plate 1, compared to placing the drive mechanism in the width or thickness direction of the air guide plate, placing the drive mechanism 4 on the length direction reduces airflow obstruction, resulting in lower wind resistance and improved airflow flow.

[0037] The drive mechanism 4 is located at one end of the length direction of the connecting rod 3. The connecting rod 3 is connected to each louver 2. Therefore, the drive mechanism 4 is located at one end of the arrangement direction of the multiple louvers 2.

[0038] When the drive mechanism 4 applies a force along the length of the air guide plate 1 to the connecting rod 3, the connecting rod 3 can be displaced along the length of the air guide plate 1. This causes the louver 2 to be displaced along the length of the air guide plate 1 at the rotational connection between the louver 2 and the air guide plate 1, thereby pulling the louver 2 to rotate (i.e., swing) around the rotational connection between the louver 2 and the air guide plate 1, thus changing the airflow direction of the louver 2. Since the louver 2 is rotatably connected to the air guide plate 1, and the louver 2 is also rotatably connected to the connecting rod 3, when the louver 2 rotates, the rotational connection between the louver 2 and the connecting rod 3 will also be displaced along the width of the air guide plate 1, causing the connecting rod 3 to also be displaced along the width of the air guide plate 1.

[0039] Thus, when link 3 applies force to louver 2 to drive its oscillation, louver 2 also applies a reverse resistance to link 3. This resistance is not along the length of link 3, but rather at an angle to its length. Therefore, when the drive mechanism 4 applies a force along the length of link 3 to one end of link 3, the connection between link 3 and louver 2 is subjected to resistance at an angle relative to the length of link 3. This poses a risk of link 3 bending. If link 3 bends, it cannot reliably and effectively pull louver 2 to rotate, resulting in link 3 jamming and failure.

[0040] Therefore, in this embodiment of the present invention, a connecting member 5 is provided between the louver 2 closest to the drive mechanism 4 and the drive mechanism 4. The connecting member 5, like the louver 2, is rotatably connected to the air guide plate 1 and the connecting rod 3 respectively. The connecting member 5, like the louver 2, rotates relative to the air guide plate 1 by the pull of the connecting rod 3. The rotation direction of the connecting member 5 is the same as the rotation direction of the louver 2 (for example, they both swing to the left or to the right together). However, the connecting member 5 does not need to guide the air, so the connecting member 5 does not need to be designed with the same shape as the louver 2. The connecting member 5 does not need to be provided with an air guiding surface, thereby reducing the volume and size of the connecting member 5. This allows the connecting member 5 to be close to the edge position of the air guide plate 1 on the side close to the drive mechanism 4. When the connecting member 5 rotates, it will not interfere with the structure or components at that edge position of the air guide plate 1.

[0041] The force applied by the drive mechanism 4 to the connecting rod 3 is applied to the connecting member 5. Since the connecting member 5 is closer to the drive mechanism 4 than the louver 2, the lever arm is shortened, effectively reducing the bending moment on the connecting rod 3 compared to a design without the connecting member 5, thus reducing the risk of bending. Furthermore, because the connecting member 5 is positioned between the louver 2 closest to the drive mechanism 4 and the drive mechanism 4, and the connecting member 5 rotates in the same direction as the louver 2, the two ends of the connecting rod 3 located between the connecting member 5 and the louver 2 closest to the drive mechanism 4 experience the same force direction. This makes this part of the connecting rod 3 (i.e., the part of the connecting rod 3 most prone to deformation in a design without the connecting member 5) less likely to deform, thereby reducing the risk of bending and allowing the connecting rod 3 to reliably and effectively pull the louver 2 to rotate. Similarly, the risk of bending in the connecting rod 3 between multiple louvers 2 is also lower, enhancing the overall reliability of the connecting rod 3's movement and improving the operational stability of driving the louver 2 to oscillate.

[0042] As described above, by providing a connector 5 between the louver 2 closest to the drive mechanism 4 and the drive mechanism 4, and by having the connector 5, like the louver 2, pulled by the connecting rod 3 and rotating in the same direction as the louver 2, the risk of the connecting rod 3 bending due to the resistance of the louver 2 can be effectively reduced when the drive mechanism 4 drives the connecting rod 3. This allows the connecting rod 3 to reliably and effectively drive the louver 2 to rotate under the drive of the drive mechanism 4. Moreover, since the connector 5 does not need to guide airflow, its volume can be designed to be small, allowing it to be placed in a smaller space between the louver 2 closest to the drive mechanism 4, thus reducing the risk of the connecting rod 3 bending.

[0043] In some embodiments of this utility model, such as Figure 2 As shown, the louver 2 has a first rotating part 21 for rotatably connecting with the air guide plate 1 and a second rotating part 22 for rotatably connecting with the connecting rod 3. The connector 5 has a third rotating part 51 for rotatably connecting with the air guide plate 1 and a fourth rotating part 52 for rotatably connecting with the connecting rod 3. The axes of the first rotating part 21 and the second rotating part 22 are parallel and the distance between them is a first distance L1. The axes of the third rotating part 51 and the fourth rotating part 52 are parallel and the distance between them is a second distance L2. The second distance L2 is equal to the first distance L1.

[0044] The louver 2 oscillates relative to the air guide plate 1 with the first rotating part 21 as the rotation center. The second rotating part 22 is rotatably connected to the connecting rod 3. The second rotating part 22 of the louver 2 is pulled by the connecting rod 3 and rotates relative to the connecting rod 3 to perform an oscillating motion. The second rotating part 22 rotates with the first rotating part 21 as the rotation center. The axis of the second rotating part 22 is parallel to the axis of the first rotating part 21. The posture of the louver 2 is more stable when rotating, reducing the possibility of the louver 2 being pulled and tipping over.

[0045] Similarly, the connector 5 swings relative to the air guide plate 1 with the third rotating part 51 as the rotation center, the fourth rotating part 52 is rotatably connected to the connecting rod 3, the fourth rotating part 52 of the louver 2 is pulled by the connecting rod 3 and rotates relative to the connecting rod 3 to perform swinging motion, and the axis of the fourth rotating part 52 is also parallel to the axis of the third rotating part 51.

[0046] The distance between the axis of the first rotating part 21 and the axis of the second rotating part 22 is the first spacing L1, and the distance between the axis of the third rotating part 51 and the axis of the fourth rotating part 52 is the second spacing L2. The first spacing L1 and the second spacing L2 are equal. The first rotating part 21, the second rotating part 22, the third rotating part 51 and the fourth rotating part 52 are constructed as four points of a quadrilateral. The first spacing L1 and the second spacing L2 are constructed as the lengths of two opposite sides. The spacing between the first rotating part 21 and the third rotating part 51 is a fixed distance on the air guide plate 1, and the spacing between the second rotating part 22 and the fourth rotating part 52 is a fixed distance on the connecting rod 3.

[0047] When the connecting rod 3 drives the louver 2 and the connecting piece 5 to rotate, the edge between the first rotating part 21 and the second rotating part 22 rotates synchronously with the edge between the third rotating part 51 and the fourth rotating part 52. By designing the first spacing L1 and the second spacing L2 to be equal, the edge connecting the second rotating part 22 and the fourth rotating part 52 moves stably, and the connecting rod 3 between the second rotating part 22 and the fourth rotating part 52 is subjected to a stable force direction and is not prone to bending.

[0048] When the distance between the third rotating part 51 and the fourth rotating part 52 on the connecting member 5 is too small, when the connecting rod 3 is pulled for the same stroke, the rotation angle of the connecting member 5 is larger, while the rotation angle of the louver 2 is smaller. The force direction of the connecting rod 3 between the second rotating part 22 and the fourth rotating part 52 is unstable, which is not conducive to the stable movement of the connecting rod 3. Furthermore, there is a possibility that the connecting member 5 reaches its limit position earlier, limiting the connecting rod 3, which leads to a decrease in the swing angle of the louver 2.

[0049] By designing the first spacing L1 and the second spacing L2 to be equal, the connecting rod 3 between the second rotating part 22 and the fourth rotating part 52 is stable in the direction of force and is not prone to bending, and the connecting piece 5 does not affect the swing angle range of the louver 2.

[0050] Furthermore, when the lengths of the side formed between the first rotating part 21 and the third rotating part 51 are equal to the lengths of the side formed between the second rotating part 22 and the fourth rotating part 52, the first rotating part 21, the second rotating part 22, the third rotating part 51, and the fourth rotating part 52 are constructed as four points of a parallelogram. When the connecting rod 3 drives the louver 2 and the connecting member 5 to rotate, the louver 2 and the connecting member 5 move synchronously, and the connecting member 5 does not affect the swing angle range of the louver 2.

[0051] For example, the connecting rod 3 not only slides along the length direction X of the air guide plate 1, but also moves relative to the width direction of the air guide plate 1. The multi-directional movement of the connecting rod 3 forms an arc-shaped movement trajectory, thereby driving the louver 2 to rotate around the connection point with the air guide plate 1. When the connecting rod 3 moves, it causes the parallelogram formed by the first rotating part 21, the second rotating part 22, the third rotating part 51, and the fourth rotating part 52 to deform. However, the opposite side lengths of the parallelogram are consistent, so that the first rotating part 21, the second rotating part 22, the third rotating part 51, and the fourth rotating part 52 always form a stable parallelogram. The sides between the first rotating part 21 and the third rotating part 51 maintain parallel movement, the connecting rod 3 is subjected to uniform force, and the risk of bending of the connecting rod 3 is low.

[0052] In some embodiments of this utility model, such as Figure 2 As shown, the louver 2 has a first rotating part 21 for rotatably connecting with the air guide plate 1 and a second rotating part 22 for rotatably connecting with the connecting rod 3. The connector 5 has a third rotating part 51 for rotatably connecting with the air guide plate 1 and a fourth rotating part 52 for rotatably connecting with the connecting rod 3. The axes of the first rotating part 21 and the third rotating part 51 are parallel and the distance between them is the third distance L3. The axes of the second rotating part 22 and the fourth rotating part 52 are parallel and the distance between them is the fourth distance L4. The third distance L3 and the fourth distance L4 are equal.

[0053] By designing the third spacing L3 and the fourth spacing L4 to be equal, the first rotating part 21, the second rotating part 22, the third rotating part 51 and the fourth rotating part 52 can be constructed as four points of a parallelogram, so that when the connecting rod 3 drives the louver 2 and the connecting piece 5 to rotate, the louver 2 and the connecting piece 5 move synchronously, and the connecting piece 5 does not affect the swing angle range of the louver 2.

[0054] Furthermore, the first rotating part 21 is rotatably connected to the air guide plate 1, and the third rotating part 51 is also rotatably connected to the air guide plate 1. The dimension of the third distance L3 between the first rotating part 21 and the third rotating part 51 can also be regarded as the dimension between the part of the air guide plate 1 that mates with the louver 2 and the part that mates with the connecting piece 5. Similarly, the second rotating part 22 is rotatably connected to the connecting rod 3, and the fourth rotating part 52 is rotatably connected to the connecting rod 3. The dimension of the fourth distance L4 between the second rotating part 22 and the fourth rotating part 52 can also be regarded as the dimension between the part of the connecting rod 3 that mates with the louver 2 and the connecting piece 5. By designing the third distance L3 and the fourth distance L4 to be equal, the spacing of the mating points on the air guide plate 1 and the connecting rod 3 can be designed to be the same size, which can reduce the design difficulty and help reduce the fit tolerance.

[0055] In some embodiments of this utility model, such as Figure 2As shown, the louver 2 has a first rotating part 21 for rotatably connecting to the air guide plate 1 and a second rotating part 22 for rotatably connecting to the connecting rod 3. The connecting member 5 has a third rotating part 51 for rotatably connecting to the air guide plate 1 and a fourth rotating part 52 for rotatably connecting to the connecting rod 3. The axes of the first rotating part 21 and the second rotating part 22 are parallel and the distance between them is a first distance L1. The axes of the third rotating part 51 and the fourth rotating part 52 are parallel and the distance between them is a second distance L2, which is equal to the first distance L1. Furthermore, the axes of the first rotating part 21 and the third rotating part 51 are parallel and the distance between them is a third distance L3. The axes of the second rotating part 22 and the fourth rotating part 52 are parallel and the distance between them is a fourth distance L4, which is equal to the third distance L3 and the fourth distance L4.

[0056] The connecting rod 3 not only slides along the length direction X of the air guide plate 1, but also moves relative to the width direction of the air guide plate 1. The multi-directional movement of the connecting rod 3 forms an arc-shaped movement trajectory, which can drive the louver 2 to rotate around the connection point with the air guide plate 1.

[0057] The first rotating part 21, the second rotating part 22, the third rotating part 51, and the fourth rotating part 52 are constructed as four points of a parallelogram. When the connecting rod 3 moves, it causes the parallelogram formed by these four parts to deform. However, the opposite sides of the parallelogram have the same length, ensuring that the first rotating part 21, the second rotating part 22, the third rotating part 51, and the fourth rotating part 52 always form a stable parallelogram. The sides between the first rotating part 21 and the third rotating part 51 remain parallel during overall movement, resulting in uniform force on the connecting rod 3 and a lower risk of bending.

[0058] In some embodiments of this utility model, such as Figure 2 and Figure 10 As shown, the air guide plate 1 has multiple first mounting portions 11 spaced apart along the length X direction of the air guide plate 1 and arranged collinearly at their centers. Multiple louvers 2 and connecting pieces 5 are rotatably connected to their respective first mounting portions 11. Figure 3 As shown, the connecting rod 3 has a plurality of second mounting portions 31 spaced apart along the length direction of the connecting rod 3 and arranged collinearly at their centers. A plurality of louvers 2 and connectors 5 are rotatably connected to the corresponding second mounting portions 31.

[0059] Multiple first mounting parts 11 are collinear with the first line M1, which facilitates the processing of the air guide plate 1. Multiple second mounting parts 31 are collinear with the second line M2, which facilitates the processing of the connecting rod 3 and reduces the manufacturing difficulty.

[0060] Furthermore, the fact that multiple first mounting parts 11 and multiple second mounting parts 31 are collinear can improve the overall integrity of multiple louvers 2 and improve the air guiding effect. The connector 5 is also rotatably connected to the first mounting parts 11 and the second mounting parts 31, which is also conducive to the synchronous movement of the connector 5 and the louvers 2 and reduces the influence of the connector 5 on the swing angle of the louvers 2.

[0061] like Figure 2 and Figure 3 As shown, the center distance L5 between the two first mounting portions 11 near the drive mechanism 4 is equal to the center distance L6 between the two second mounting portions 31 near the drive mechanism 4.

[0062] The connector 5 is located between the louver 2 and the drive mechanism 4, which is closest to the drive mechanism 4. Therefore, the two first mounting portions 11 near the drive mechanism 4 are respectively rotatably connected to the louver 2 and the connector 5, and the two second mounting portions 31 near the drive mechanism 4 are respectively rotatably connected to the louver 2 and the connector 5. The first rotating portion 21 and the third rotating portion 51 are respectively rotatably connected to the two first mounting portions 11, and the second rotating portion 22 and the fourth rotating portion 52 are respectively rotatably connected to the two second mounting portions 31.

[0063] By designing the center distance L5 between the two first mounting portions 11 near the drive mechanism 4 and the center distance L6 between the two second mounting portions 31 near the drive mechanism 4 to be equal, they can cooperate with the first rotating portion 21, the third rotating portion 51, the second rotating portion 22 and the fourth rotating portion 52. The louvers 2 and the connectors 5 with equal third spacing L3 and fourth spacing L4 can be stably cooperated with the two first mounting portions 11 near the drive mechanism 4 and the two second mounting portions 31 near the drive mechanism 4.

[0064] In some embodiments of this utility model, the center distance between any two adjacent first mounting parts 11 and the center distance between any two adjacent second mounting parts 31 are equal, which facilitates the processing of the air guide plate 1 and the connecting rod 3, and reduces the manufacturing difficulty.

[0065] In some embodiments of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, the louver 2 has a first rotating part 21 for rotatably connecting with the air guide plate 1, and the connector 5 has a third rotating part 51 for rotatably connecting with the air guide plate 1; as Figure 2 As shown, along the length of the connecting rod 3, the center distance L3 between the first rotating part 21 and the third rotating part 51 is greater than the distance L7 from the third rotating part 51 to the edge of the air guide plate 1 near the drive mechanism 4.

[0066] The connector 5 is located between the louver 2 and the drive mechanism 4, which is closest to the drive mechanism 4. The connector 5 reduces the bending moment on the connecting rod 3. The connector 5 does not need to guide the air. Therefore, the connector 5 is located closer to the edge of the air guide plate 1 near the drive mechanism 4. The connector 5 can be arranged in a small space between the louver 2 and the drive mechanism 4, which reduces the influence on the air guiding effect of the air guide plate 1.

[0067] In some embodiments of this utility model, such as Figure 2 and Figure 5 As shown, the connector 5 has a third rotating part 51 for rotatably connecting with the air guide plate 1 and a fourth rotating part 52 for rotatably connecting with the connecting rod 3. The connector 5 also includes a connecting rod 53 connected between the third rotating part 51 and the fourth rotating part 52. Both the third rotating part 51 and the fourth rotating part 52 are rotating shafts. The third rotating part 51 extends toward the air guide plate 1 relative to the connecting rod 53, and the fourth rotating part 52 extends away from the air guide plate 1 relative to the connecting rod 53.

[0068] The connecting piece 5 oscillates relative to the air guide plate 1 with the third rotating part 51 as the rotation center. The fourth rotating part 52 is rotatably connected to the connecting rod 3. The fourth rotating part 52 of the louver 2 is pulled by the connecting rod 3 and rotates relative to the connecting rod 3 to perform an oscillating motion. A connecting rod 53 connects the third rotating part 51 and the fourth rotating part 52. The fourth rotating part 52 moves along a circular trajectory with the third rotating part 51 as the rotation center and the connecting rod 53 as the radius.

[0069] Both the third rotating part 51 and the fourth rotating part 52 are rotating shafts. Correspondingly, the air guide plate 1 is provided with a rotating hole that mates with the third rotating part 51, and the connecting rod 3 is provided with a rotating hole that mates with the fourth rotating part 52.

[0070] The air guide plate 1 and the connecting rod 3 are spaced apart, and the connecting piece 5 is disposed between the connecting rod 3 of the air guide plate 1. The third rotating part 51 of the connecting piece 5 extends toward the air guide plate 1 relative to the connecting rod 53, and the fourth rotating part 52 of the connecting piece 5 extends toward the direction away from the air guide plate 1 relative to the connecting rod 53. That is, the fourth rotating part 52 of the connecting piece 5 extends toward the connecting rod 3 relative to the connecting rod 53.

[0071] In some embodiments of this invention, the volume of the connector 5 is smaller than that of the louver 2; for example, the louver 2 has an additional air-guiding section compared to the connector 5. This reduces the installation space required for the connector 5.

[0072] For example, such as Figure 5 As shown, the connector 5 consists of a third rotating part 51, a fourth rotating part 52 and a connecting rod 53. As a result, the connector 5 has a small size and volume, which reduces costs and occupies little installation space.

[0073] In some other embodiments of this utility model, both the third rotating part 51 and the fourth rotating part 52 are constructed as rotating holes. Correspondingly, the air guide plate 1 is provided with a rotating shaft that cooperates with the third rotating part 51, and the connecting rod 3 is provided with a rotating shaft that cooperates with the fourth rotating part 52. Of course, this is not limited to this; the third rotating part 51 and the fourth rotating part 52 can also be other rotatable structural forms, which can be selected according to actual needs.

[0074] In some embodiments of this utility model, such as Figure 5 As shown, the diameter D3 of the third rotating part 51 is larger than the diameter D4 of the fourth rotating part 52.

[0075] The connector 5 swings relative to the air guide plate 1 with the third rotating part 51 as the rotation center. Therefore, the diameter D3 of the third rotating part 51 is designed to be larger than the diameter D4 of the fourth rotating part 52, which can improve the rotational stability of the connector 5.

[0076] In some embodiments of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, the louver 2 has a first rotating part 21 for rotatably connecting with the air guide plate 1 and a second rotating part 22 for rotatably connecting with the connecting rod 3. The first rotating part 21 is constructed as a rotating shaft with the same diameter as the third rotating part 51, and the second rotating part 22 is constructed as a rotating shaft with the same diameter as the fourth rotating part 52.

[0077] The louver 2 swings relative to the air guide plate 1 with the first rotating part 21 as the rotation center. The second rotating part 22 is rotatably connected to the connecting rod 3. The second rotating part 22 of the louver 2 is pulled by the connecting rod 3 and rotates relative to the connecting rod 3 to perform swinging motion.

[0078] Both the first rotating part 21 and the second rotating part 22 are constructed as rotating shafts. Correspondingly, the air guide plate 1 is provided with a rotating hole that mates with the first rotating part 21, and the connecting rod 3 is provided with a rotating hole that mates with the second rotating part 22. By designing the diameter D1 of the first rotating part 21 to be larger than the diameter D2 of the second rotating part 22, the rotational stability of the louver 2 can be improved.

[0079] By designing the diameter D1 of the first rotating part 21 to be equal to the diameter D3 of the third rotating part 51, and designing the diameter D2 of the second rotating part 22 to be equal to the diameter D4 of the fourth rotating part 52, the mating parts on the air guide plate 1 with the louvers 2 and the connecting parts 5 can be designed to be consistent, and the mating parts on the connecting rod 3 with the louvers 2 and the connecting parts 5 can be designed to be consistent, which facilitates the processing of the air guide plate 1 and the connecting rod 3, and reduces the manufacturing difficulty.

[0080] In some other embodiments of this utility model, both the first rotating part 21 and the second rotating part 22 are constructed as rotating holes. Correspondingly, the air guide plate 1 is provided with a rotating shaft that cooperates with the first rotating part 21, and the connecting rod 3 is provided with a rotating shaft that cooperates with the second rotating part 22. Of course, this is not limited to this; the first rotating part 21 and the second cooperating part can also be other rotatable structural forms, which can be selected according to actual needs.

[0081] In some embodiments of this utility model, the air guide plate 1 and the connecting rod 3 are spaced apart, and the louver 2 also includes an air guide part 23. The first rotating part 21 and the second rotating part 22 are both connected to the air guide plate 1. The movement of the first rotating part 21 and the second rotating part 22 drives the air guide plate 1 to swing and guide the air. Most of the air guide part 23 is located on the side of the connecting rod 3 away from the air guide plate 1.

[0082] Both the first rotating part 21 and the second rotating part 22 are pivots, and both extend towards the guide vane 1. The second rotating part 22 extends from the side of the connecting rod 3 away from the guide vane 1 to the connecting rod 3 to cooperate with the connecting rod 3. Compared with placing the second rotating part on the side of the connecting rod closer to the guide vane, the second rotating part 22 in this embodiment of the present invention has a simpler structure, stronger motion stability, and can reduce motion interference with the connecting rod 3 or the guide vane 1.

[0083] Both the third rotating part 51 and the fourth rotating part 52 are constructed as rotating shafts. Since the connecting member 5 does not need to guide airflow, it does not have an airflow guiding structure. The third rotating part 51 and the fourth rotating part 52 are connected by a connecting rod 53. Therefore, the connecting member 5 is relatively small. The connecting rod 53 is positioned between the connecting rods 3 of the air guide plate 1. The third rotating part 51 extends towards the air guide plate 1 relative to the connecting rod 53, and the fourth rotating part 52 extends towards the connecting rod 3 relative to the connecting rod 53. The connecting member 5 occupies less space on the side of the connecting rod 3 away from the air guide plate 1, thus reducing its space requirement. Therefore, the connecting member 5 can be positioned at the end near the air guide plate 1 where space is limited.

[0084] In some embodiments of this utility model, such as Figure 6 As shown, the drive mechanism 4 includes a drive rod 41 that is telescopic along the length of the connecting rod 3, and the drive rod 41 includes a drive shaft 411; as Figure 7 and Figure 8As shown, the end of the connecting rod 3 near the drive mechanism 4 is configured as a connecting portion 32. The connecting member 5 is rotatably connected to the connecting portion 32. A groove 321 is formed on the connecting portion 32. The length direction Y of the groove 321 is perpendicular to the length direction of the connecting rod 3. The connecting portion 32 cooperates with the drive shaft 411 through the groove 321, so that the connecting rod 3 and the drive rod 41 move synchronously along the length direction of the connecting rod 3, and the drive shaft 411 can slide relative to the groove 321 along the length direction of the groove 321, and the connecting rod 3 can rotate relative to the drive rod 41 about the drive shaft 411. The drive shaft 411 is cylindrical.

[0085] The drive mechanism 4 includes a telescopic drive rod 41. The extension and retraction of the drive rod 41 can drive the connecting rod 3 to move along the length direction of the connecting rod 3. The drive rod 41 includes a drive shaft 411, which is directly engaged with the connecting part 32 at the end of the connecting rod 3.

[0086] A groove 321 is formed on the connecting part 32. The length direction Y of the groove 321 is perpendicular to the length direction of the connecting rod 3. The connecting part 32 cooperates with the drive shaft 411 through the groove 321.

[0087] The drive shaft 411 cooperates with the slide groove 321. The extension and retraction of the drive rod 41 drives the drive shaft 411 to move along the length direction of the connecting rod 3, which in turn drives the connecting rod 3 to move along the length direction of the connecting rod 3.

[0088] The connecting part 32 engages with the drive shaft 411 via a groove 321. The drive shaft 411 can slide relative to the groove 321 along its length, thus allowing the connecting part 32 to move relative to the drive shaft 411 along a length direction perpendicular to the connecting rod 3. Consequently, the drive shaft 411 can drive the connecting rod 3 to move along its length and also drive it to move along a length direction perpendicular to the connecting rod 3. The movement of the connecting rod 3 in these two directions can be combined to form an arc-shaped trajectory motion relative to the air guide plate 1. In this way, the connecting rod 3 can cause the louvers 2 and the connecting piece 5 to swing relative to the air guide plate 1, improving the motion stability of the louvers 2 and the connecting piece 5.

[0089] The connecting part 32 engages with the drive shaft 411 via a groove 321, and the drive shaft 411 can slide relative to the groove 321 along the length direction of the groove 321. When the end of the groove 321 is open, the drive shaft 411 can slide from the open along the groove 321 to complete the engagement with the groove 321. Furthermore, since the length direction of the groove 321 is perpendicular to the length direction of the connecting rod 3, the drive shaft 411 is less likely to slide out of the groove 321 when moving along the length direction of the connecting rod 3. This can improve the stability of the engagement between the drive shaft 411 and the connecting part 32 while reducing the assembly difficulty of the drive shaft 411 and the connecting part 32.

[0090] The connecting part 32 engages with the drive shaft 411 via a groove 321, allowing the connecting rod 3 to rotate relative to the drive rod 41 around the drive shaft 411. It is understood that the air guide plate 1 requires rotational airflow guidance, therefore the louvers 2 also rotate with the air guide plate 1, and the connecting rod 3, which is connected to multiple louvers 2, will also rotate synchronously. By providing a groove 321 on the connecting part 32, the drive shaft 411 can pass through the groove 321 and rotatably engage with the connecting part 32, thereby allowing the connecting rod 3 to rotate relative to the drive rod 41 around the drive shaft 411.

[0091] The connector 5 requires less space, allowing it to be positioned on the connecting portion 32 near the end of the air guide plate 1, resulting in a compact structure. Furthermore, the connecting portion 32 increases the structural complexity of the end of the connecting rod 3, thereby improving the structural stability of the connecting rod 3 and enhancing the stability of the fit between the connector 5 and the connecting portion 32.

[0092] In some embodiments of this utility model, such as Figure 7 As shown, one end of the slide groove 321 is open in the length direction to form a groove opening 322. The drive rod 41 is adapted to cooperate with the slide groove 321 through the groove opening 322. The groove opening 322 is formed as a flared groove facing away from the slide groove 321.

[0093] The drive shaft 411 can slide into the slide groove 321 from the slot opening 322 to complete the engagement with the slide groove 321. Since the length direction of the slide groove 321 is perpendicular to the length direction of the connecting rod 3, the drive shaft 411 is not easy to slide out of the slide groove 321 when it moves along the length direction of the connecting rod 3. This can improve the engagement stability of the drive shaft 411 and the connecting part 32, while reducing the assembly difficulty of the drive shaft 411 and the connecting part 32.

[0094] The slot opening 322 is formed as an flared slot facing away from the slide groove 321. When the drive shaft 411 slides from the slot opening 322 into the slide groove 321, the slot opening 322 forms a constricted structure, which guides the movement of the drive shaft 411 and further reduces the assembly difficulty of the drive shaft 411 and the connecting part 32.

[0095] In some embodiments of this utility model, such as Figures 7-9 As shown, the connecting part 32 includes a sliding plate 323, a sliding groove 321 is formed on the sliding plate 323, and the drive shaft 411 includes a reduced diameter section 4111 and a stop section 4112 connected to both axial sides of the reduced diameter section 4111. The diameter D5 of the reduced diameter section 4111 is smaller than the diameter D6 of the stop section 4112. The reduced diameter section 4111 fits into the sliding groove 321, and the two stop sections 4112 stop on both sides of the sliding plate 323 respectively.

[0096] The slide groove 321 extends through the slide plate 323 along the length of the connecting rod 3. The drive shaft 411 passes through the slide groove 321. The smaller diameter reduced section 4111 fits into the slide groove 321, while the two larger diameter stop sections 4112 abut against the sides of the slide plate 323 respectively. The slide plate 323 thus limits the movement of the drive shaft 411, ensuring a stable fit between the drive shaft 411 and the connecting part 32. The drive shaft 411 can drive the connecting part 32 to move stably. Furthermore, it reduces the wobbling of the drive shaft 411 relative to the connecting part 32 in the length direction of the connecting rod 3, minimizing the possibility of misalignment of the connecting rod 3 relative to the drive shaft 411.

[0097] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the two ends of the connecting part 32 in the length direction of the connecting rod 3 are end plates 324. The connecting part 32 includes at least one connecting plate 325 connected between the two end plates 324. The connecting member 5 is rotatably connected to one of the connecting plates 325. The sliding groove 321 is formed on the end plate 324 of the two end plates 324 that is closer to the driving mechanism 4.

[0098] The connecting part 32 includes end plates 324 spaced apart along the length of the connecting rod 3 and a connecting plate 325 connected between the two end plates 324. The connecting member 5 is rotatably connected to the connecting plate 325. The connecting part 32 has stronger structural stability, and the connecting member 5 provided on the connecting part 32 can improve the connection stability between the connecting part 32 and the connecting rod 3.

[0099] The end of the connecting rod 3 near the drive mechanism 4 is configured as a connecting part 32. A groove 321 is formed on the end plate 324 of the connecting part 3 near the drive mechanism 4 in the length direction of the connecting rod 3. The groove 321 is located closest to the drive mechanism 4, which can improve the stability of the cooperation between the drive shaft 411 and the groove 321 and reduce the motion interference between the drive shaft 411 and other structures.

[0100] In some embodiments of this utility model, such as Figure 8 and Figure 10 As shown, the air guide plate 1 has a plurality of first mounting portions 11 spaced apart along the length direction X of the air guide plate 1. A plurality of louvers 2 and connectors 5 are rotatably connected to the corresponding first mounting portions 11. The first mounting portion 11 is a mounting hole 111. The distance L8 between the two end plates 324 along the length direction of the connecting rod 3 is greater than the diameter D9 of the mounting hole 111.

[0101] The distance L8 between the two end plates 324 along the length of the connecting rod 3 is greater than the diameter D9 of the mounting hole 111. The dimension of the connecting part 32 along the length of the connecting rod 3 covers the mounting hole 111 on the air guide plate 1, thereby making the size of the connecting part 32 larger and the structural stability of the connecting part 32 stronger. The connecting piece 5 is set on the connecting part 32 to improve the connection stability between the connecting part 32 and the connecting rod 3.

[0102] In some embodiments of this utility model, such as Figure 7 As shown, the connecting rod 3 also includes a rod body 33 and a transition portion 34. The transition portion 34 is connected between the rod body 33 and the connecting portion 32. The rod body 33 is a straight rod of equal width. The louver 2 is rotatably connected to the rod body 33. The width of the transition portion 34 gradually increases along the direction from the rod body 33 to the connecting portion 32.

[0103] The width of the connecting part 32 is greater than the width of the rod body 33, and the width of the transition part 34 gradually increases along the direction from the rod body 33 to the connecting part 32, which can improve the stability of the fit between the drive shaft 411 and the connecting part 32 and improve the reliability of the drive shaft 411 driving the connecting rod 3.

[0104] In some embodiments of this utility model, the drive rod 41 further includes a rack extending along the length of the connecting rod 3, and the drive shaft 411 is connected to the side of the rack near the connecting rod 3, such as... Figure 6 As shown, the drive mechanism 4 includes a motor 42 and a gear. The motor 42 drives the gear to rotate, and the gear meshes with the rack.

[0105] The drive rod 41 also includes a rack, which can move along the length of the connecting rod 3. The drive shaft 411 is connected to the side of the rack near the connecting rod 3. When the rack moves, it can drive the drive shaft 411 to extend and retract along the length of the connecting rod 3.

[0106] The drive mechanism 4 includes a motor 42 and a gear. The motor 42 drives the gear to rotate, and the gear meshes with the rack to move the rack along the length of the connecting rod 3. The gear and rack have a simple meshing structure and strong meshing stability, which can improve the working stability of the drive mechanism 4.

[0107] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the louver 2 is rotatably connected to the connecting rod 3 via a rotating shaft. When the rack moves, it drives the drive shaft 411 to extend or retract along the length of the connecting rod 3. The drive shaft 411 then drives the connecting rod 3 to slide along its length. Simultaneously, the drive shaft 411 also slides into the groove 321, allowing the connecting rod 3 to move relative to the drive shaft 411 in a direction perpendicular to its length. The movement of the connecting rod 3 in both directions can be combined to form an arc-shaped trajectory relative to the air guide plate 1. In this way, the connecting rod 3 can cause the louver 2 to oscillate relative to the air guide plate 1, improving the movement stability of the louver 2.

[0108] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the drive mechanism 4 also includes a gear box 44, a motor 42 is located outside the gear box 44, gears and racks are located inside the gear box 44, and a drive shaft 411 extends out of the gear box 44. The gear box 44 includes a support shaft 441, which includes a shaft segment 4411 and shoulders 4412 located on both axial sides of the shaft segment 4411. The diameter D7 of the shaft segment 4411 is smaller than the diameter D8 of the shoulders 4412. The end of the air guide plate 1 near the drive mechanism 4 includes a pivot portion 12. A pivot hole 121 with a side opening is formed on the pivot portion 12. The shaft segment 4411 pivotally engages with the pivot hole 121 through the side opening, and the two shoulders 4412 abut against both sides of the pivot portion 12.

[0109] Both the gear and rack are housed inside the gear box 44, which provides support and protection for the gear and rack, improving the structural compactness. The drive shaft 411 extends out of the gear box 44 to engage with the connecting part 32.

[0110] The end of the air guide plate 1 near the drive mechanism 4 includes a pivot portion 12. The pivot portion 12 has a pivot hole 121 with a side opening, which allows the support shaft 441 to be moved into the pivot hole 121, facilitating the assembly of the support shaft 441 and the pivot portion 12. The smaller diameter shaft section 4411 extends into the pivot hole 121 and pivotally engages with the pivot portion 12. The two larger diameter shaft shoulders 4412 abut against the sides of the pivot portion 12. The pivot portion 12 can thus limit the position of the support shaft 441, reducing the sway of the support shaft 441 relative to the pivot portion 12 in the length direction X of the air guide plate 1, improving the arrangement stability of the gear box 44, and enhancing the working reliability of the drive mechanism 4.

[0111] In some embodiments of this utility model, the air guide component 100 further includes an air guide plate driving device. The air guide plate driving device and the driving mechanism 4 are respectively disposed on both sides of the air guide plate 1 in the length direction X. The air guide plate driving device is connected to the air guide plate 1 to drive the air guide plate 1 to rotate around the shaft segment 4411.

[0112] The air guide plate drive device and the drive mechanism 4 are respectively located on both sides of the length direction X of the air guide plate 1. The reasonable arrangement of the air guide plate drive device and the drive mechanism 4 reduces mutual interference and improves the working reliability of the air guide plate drive device and the drive mechanism 4.

[0113] An air conditioner according to a second aspect of the present invention includes an air guide component 100 according to a first aspect of the present invention, wherein an air guide plate 1 is rotatably disposed at the air outlet of the air conditioner.

[0114] The type of air conditioner is not limited; it can be an integrated air conditioning unit (such as a window air conditioner or a kitchen air conditioner) or a split air conditioning unit (such as a floor-standing air conditioner or a wall-mounted air conditioner). For example, when the air conditioner is a floor-standing unit, the air outlet can be vertically positioned, and the length direction X of the air guide plate 1 is arranged vertically. For example, when the air conditioner is a wall-mounted unit, the air outlet can be horizontally positioned, and the length direction X of the air guide plate 1 is arranged horizontally.

[0115] The air guide plate 1 can rotate to guide the airflow, and the louvers 2 can also swing to guide the airflow. The air guide plate 1 and the louvers 2 can guide the airflow in different directions, which can improve the air outlet range of the air conditioner. By setting the air guide component 100 of the first aspect of this utility model, the movement stability of the connecting rod 3 is strong, which can improve the air outlet reliability of the air conditioner.
