These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0051] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] The terms "first," "second," "third," "fourth," and so on (if any) in the specification and claims of this application and the drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0053] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0054] Furthermore, the terms "disposed," "connected," and "fixed" should be interpreted broadly. For example, "connected" can mean a fixed connection, a removable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediary, or an internal connection between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the embodiments of this disclosure based on the specific circumstances.

[0055] Unless otherwise stated, the term "plurality" means two or more.

[0056] As can be seen from the background technology, the air guide structure is an important component of the air conditioner, which can play a certain role in guiding the wind from the air conditioner body, thereby changing the air outlet direction of the air conditioner body and improving the air outlet effect of the air conditioner.

[0057] In existing air conditioners, extension plates are often designed on the air guide plates to improve the airflow and enhance the directionality and uniformity of air flow. This extension plate is movably mounted relative to the air guide plate and can be extended when needed to extend the air guide plate's airflow length, effectively increasing the airflow path. This makes the airflow from the air conditioner softer and covers a wider area, significantly improving the user's comfort experience.

[0058] In the prior art, the extension plate is typically slidably connected to the air deflector. As the air deflector gradually opens under the drive of a motor, gravity forces the extension plate to slide smoothly along pre-set rails, expanding the air guide path. This design simplifies the extension plate's drive mechanism and reduces manufacturing costs.

[0059] However, this type of extension plate, which relies solely on gravity for propulsion, suffers from instability during operation. Due to the uncontrollable nature of gravity-driven propulsion, the extension plate is prone to jamming during its extension and retraction, resulting in unstable movement and poor airflow. This can even damage the extension plate or the slide rail structure, impacting the overall performance of the air conditioner.

[0060] To address the issue of stalling, some researchers have attempted to use a gear and rack system to drive the extension panel. This approach provides a more stable and smooth drive, but its driving range is limited by the size of the gear and rack, making it difficult to accommodate extension panels of varying lengths. Furthermore, the installation and maintenance of the gear and rack system are relatively complex, increasing the cost of air conditioner manufacturing and subsequent maintenance.

[0061] To solve the above problems, an embodiment of the present application provides an air guide structure and an air conditioner, wherein the air guide structure includes an air guide plate, an extension plate and a driving assembly; the driving assembly includes a driving member, a first connecting rod and a second connecting rod; the driving member is arranged on the air guide plate, and the output shaft of the driving member is connected to the first end of the first connecting rod, the second end of the first connecting rod is rotatably connected to the first end of the second connecting rod, and the second end of the second connecting rod is rotatably connected to the extension plate; the driving member can drive the first connecting rod and the second connecting rod to move, so as to drive the extension plate to move along the air guiding direction of the air guide plate, thereby ensuring the smoothness of the movement of the extension plate relative to the air guide plate, avoiding the phenomenon of the extension plate being stuck and the movement process being unstable; and, only the size of the first connecting rod and the second connecting rod needs to be adjusted to change the movement range of the extension plate, which is more convenient to adapt to the situation where the extension plate needs to move long distances, and the installation and maintenance are relatively simple; there is no need to carry out complex installation design in order to replace and install a longer rack and maintain the meshing stability of the gear and the rack.

[0062] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can exist independently or in combination with each other. For the same or similar concepts or processes, they may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0063] Combine Figures 1 to 3 As shown, on the one hand, an embodiment of the present application provides an air guide structure, including an air guide plate 100, an extension plate 200 and a drive assembly 300; the extension plate 200 is arranged on the air guide plate 100, and the extension plate 200 can move along the air guide direction of the air guide plate 100; the drive assembly 300 includes a drive member 310, a first connecting rod 320 and a second connecting rod 330; the drive member 310 is arranged on the air guide plate 100, and the output shaft of the drive member 310 is connected to the first end of the first connecting rod 320, the second end of the first connecting rod 320 is rotatably connected to the first end of the second connecting rod 330, and the second end of the second connecting rod 330 is rotatably connected to the extension plate 200; the rotation axes of the first connecting rod 320 and the second connecting rod 330, the rotation axes of the second connecting rod 330 and the extension plate 200 are arranged parallel to the output shaft of the drive member 310.

[0064] As will be appreciated, the air deflector 100 can be hinged to the air outlet of the air conditioner. When the air conditioner is not in operation, the air deflector 100 typically blocks the air outlet, thereby closing it. When the air conditioner is in operation, the air deflector 100 can rotate relative to the air conditioner to remove the obstruction of the air outlet. Airflow from the air conditioner is discharged through the air outlet and, under the guidance of the air deflector 100, flows over a wider area, evenly distributing it within the room.

[0065] Combine Figure 1As shown, taking a ceiling-mounted air conditioner as an example, the top of the ceiling-mounted air conditioner is installed on the ceiling, and its air outlet can be opened at the bottom. The air guide plate 100 rotates relative to the air conditioner so that the plane where the air guide plate 100 is located forms a preset angle with the bottom plate of the air conditioner; during the rotation process, the rotation axis of the air guide plate 100 is aligned with the bottom plate of the air conditioner. Figure 1 The X axis is parallel to the

[0066] The extension plate 200 is arranged on the wind guide plate 100 and can move along the wind guiding direction of the wind guide plate 100. The extension plate 200 can be extended or retracted when needed, thereby dynamically adjusting the length of the wind guiding path to adapt to different usage requirements and provide a more flexible wind guiding effect.

[0067] Among them, when the extension plate 200 extends out of the air guide plate 100, the guide path of the air guide plate 100 can be enlarged, and the airflow can be directed to a wider area, so that it can be more evenly distributed in the room, thereby improving the indoor cooling or heating effect and improving the overall comfort; and, the airflow will generate certain noise when passing through the air duct. By setting the extension plate 200, the airflow can be guided to flow out more smoothly, reducing the friction and collision between the airflow and the inner wall of the air duct, thereby reducing the noise level.

[0068] Drive assembly 300 provides a stable transmission method that converts the rotational motion of drive member 310 into linear motion, providing a smooth drive effect and avoiding the instability of gravity-driven operation. The output shaft of drive member 310 is connected to the first end of first connecting rod 320, the second end of first connecting rod 320 is rotationally connected to the first end of second connecting rod 330, and the second end of second connecting rod 330 is rotationally connected to extension plate 200. This connection method ensures that the movement of drive member 310 can be effectively transmitted to extension plate 200, achieving its smooth movement. In addition, through this multi-stage connecting rod connection, the movement of drive member 310 can be amplified or reduced to adapt to different movement requirements, providing greater flexibility.

[0069] The rotating axes of the first connecting rod 320 and the second connecting rod 330, the rotating axes of the second connecting rod 330 and the extension plate 200, and the output axis of the driving member 310 are arranged in parallel, which can ensure that the various components remain well aligned during movement, thereby reducing unnecessary stress and wear, improving the smoothness of the movement process of the extension plate 200, and avoiding jamming.

[0070] Specifically, the air guide structure provided in the embodiment of the present application provides a stable and controllable extension plate 200 driving method through the drive component 300, which solves the problem of unstable movement of the extension plate 200 caused by gravity driving in the prior art; the connecting rod mechanism in the drive component 300 not only improves the smoothness of the drive, but also reduces the dependence on gears and racks, making it easier to adapt to situations where the extension plate 200 needs to move long distances, thereby reducing manufacturing and maintenance costs.

[0071] Combine Figure 3 and Figure 4 As shown, in some embodiments, the length of the first connecting rod 320 is less than the length of the second connecting rod 330 ; the length of the first connecting rod 320 is less than the distance between the output shaft of the driving member 310 and the air guide plate 100 .

[0072] Among them, the shorter first connecting rod 320 can produce greater force transmission efficiency within the limited motion range of the driving member 310, and the longer second connecting rod 330 can provide a larger range of motion, so that the extension plate 200 can move within a larger range, thereby increasing the adjustability of the air guide path.

[0073] By limiting the length of the first link 320, it is ensured that it does not exceed the physical limit range of the driving member 310 during rotation, thereby avoiding collision with the wind deflector 100 or other structures, and ensuring that the movement paths of the first link 320 and the second link 330 are not obstructed.

[0074] Specifically, by limiting the length of the first connecting rod 320 and the second connecting rod 330, the motion characteristics of the connecting rod mechanism are optimized, so that the driving assembly 300 can drive the extension plate 200 to move efficiently and smoothly within a limited space, reducing the possibility of mechanical interference and enhancing the reliability and durability of the air guide structure.

[0075] In some embodiments, the length direction of the extension plate 200 is set perpendicular to the wind guiding direction of the wind guide plate 100; the driving assembly 300 is set on one side of the length direction of the extension plate 200, and the second connecting rod 330 is rotatably connected to the end of the extension plate 200 along the length direction.

[0076] It is understood that the length of the extension plate 200 is perpendicular to the air guide direction of the air guide plate 100, and the air guide direction of the air guide plate 100 is consistent with the width of the air guide plate 100. When deployed, the extension plate 200 can extend across the width of the air guide plate 100, thereby increasing the length of the air guide path. This allows the airflow to be more evenly distributed when passing through the air guide plate 100 and the extension plate 200, thereby improving the overall air guide effect of the air conditioner.

[0077] The driving assembly 300 is arranged on one side of the extension plate 200 in the length direction, reducing the space occupied by other parts of the extension plate 200; and the second connecting rod 330 is rotatably connected to the end of the extension plate 200 along the length direction. The second connecting rod 330 can generate sufficient torque to push the extension plate 200 under the action of the driving member 310, ensuring the efficiency and stability of the drive.

[0078] Combine Figure 5As shown, in some embodiments, the wind guide plate 100 is provided with a guide member 110 , which extends along the wind guiding direction of the wind guide plate 100 , and the extension plate 200 can move relative to the guide member 110 along the wind guiding direction of the wind guide plate 100 .

[0079] It is understandable that the driving component 300 is set on one side of the extension plate 200 in the length direction. It is difficult for the driving component 300 to drive the two ends of the extension plate 200 in the length direction to move synchronously, which may cause the extension plate 200 to offset or jam during its movement.

[0080] By setting up the air guide, a stable track is provided for the movement of the extension plate 200, so that the extension plate 200 moves along the air guiding direction of the air guide plate 100, ensuring that the extension plate 200 remains stable during the movement and avoiding deviation or jamming due to uneven force.

[0081] Exemplarily, the air guide member may be a baffle bar protruding from the surface of the air guide plate 100 , and the baffle bar abuts against an end of the extension plate 200 facing away from the driving assembly 300 .

[0082] In some embodiments, the air guiding direction of the extension plate 200 is arranged parallel to the air guiding direction of the air guide plate 100; when the extension plate 200 moves relative to the air guide plate 100, at least a portion of the extension plate 200 is in contact with the air guide plate 100.

[0083] The airflow direction of extension plate 200 is arranged parallel to that of air guide plate 100, ensuring that the airflow maintains the same direction as it passes through air guide plate 100 and extension plate 200. This parallel arrangement allows extension plate 200 to extend the airflow path without changing the airflow direction, thereby enhancing the airflow coverage, helping to maintain airflow stability, reducing turbulence and airflow dispersion, and improving the overall airflow efficiency of the air conditioner.

[0084] When the extension plate 200 moves relative to the air guide plate 100, it is at least partially in contact with the air guide plate 100, so the extension plate 200 will never separate from the air guide plate 100, which can prevent the extension plate 200 from falling; in addition, the partial contact between the extension plate 200 and the air guide plate 100 helps to reduce the leakage of airflow from the connection between the extension plate 200 and the air guide plate 100, thereby reducing the loss of airflow during movement.

[0085] Combine Figures 2 to 6 As shown, in some embodiments, the air guide plate 100 is provided with a crimping piece 120, and the crimping piece 120 and the air guide plate 100 form a receiving groove 130, and the receiving groove 130 extends along the air guiding direction of the air guide plate 100; the extension plate 200 is provided in the receiving groove 130, and the first surface 210 of the extension plate 200 is in contact with the air guide plate 100, and the second surface 220 of the extension plate 200 is in contact with the crimping piece 120.

[0086] It can be understood that the accommodating groove 130 formed by the crimping piece 120 and the air guide plate 100 provides a physical constraint for the extension plate 200, so that the position of the extension plate 200 remains between the air guide plate 100 and the crimping piece 120. During the movement, the extension plate 200 is always located in the same plane as the air guide plate 100, preventing the extension plate 200 from separating from the air guide plate 100 during the movement, or forming an angle with the plane where the air guide plate 100 is located, thereby affecting the wind guiding effect.

[0087] Combine Figure 6 As shown, in some embodiments, the crimping member 120 is provided with a guide portion 121 on the side facing the air guide plate 100; the extension plate 200 is provided with a sliding portion 230, and the guide portion 121 and the sliding portion 230 can slide and cooperate along the air guiding direction of the air guide plate 100.

[0088] Exemplarily, the guide portion 121 can be a groove provided on the crimping part 120, and the extension direction of the groove is consistent with the air guiding direction of the air guide plate 100; the sliding portion 230 can be a slider provided on the extension plate 200, the slider is embedded in the groove, and the slider can slide along the groove.

[0089] In other embodiments, the sliding portion 230 may be configured as a roller to reduce friction and resistance during the movement of the extension plate 200 and improve the efficiency and smoothness of the movement of the extension plate 200 .

[0090] Specifically, by setting the guide part 121 and the sliding part 230 on the crimping part 120 and the extension plate 200, the guide part 121 provides a clear moving path, and the sliding part 230 ensures a low-friction moving environment, effectively improving the smoothness and stability of the movement of the extension plate 200.

[0091] In some embodiments, the number of the crimping members 120 is set to be multiple, and the multiple crimping members 120 are sequentially spaced along the length direction of the extension plate 200.

[0092] The plurality of crimping members 120 are sequentially spaced apart along the length direction of the extension plate 200 , which can ensure that the extension plate 200 can obtain uniform support and guidance along the entire length, and ensure that it remains stable and accurate during movement.

[0093] Combine Figure 3 and Figure 4 As shown, in some embodiments, the air guide plate 100 is provided with a base 140; the base 140 includes a base 141 and a mounting portion 142 connected to each other; the base 141 is provided on the air guide plate 100, and the surface of the base 141 facing away from the air guide plate 100 is used to place the driving member 310; at least a portion of the mounting portion 142 is provided on the side of the driving member 310 facing away from the base 141, and the mounting portion 142 and the base 141 jointly clamp and fix the driving member 310.

[0094] The base 140 can provide a stable installation platform for the driver 310 to ensure that the driver 310 remains stable during operation.

[0095] The mounting portion 142 and the base 141 jointly clamp and fix the driving member 310, thereby improving the fixing strength of the driving member 310 and preventing the driving member 310 from being displaced or vibrated during operation; the base 141 also provides a vibration isolation function, preventing the vibration generated by the driving member 310 itself during operation from being transmitted to the wind guide plate 100 and affecting the wind guiding effect.

[0096] By setting up the base 141, the driving member 310 is installed on the base 141, which increases the distance between the output shaft of the driving member 310 and the air guide plate 100. It is convenient to increase the length of the first connecting rod 320 according to actual needs, thereby increasing the moving range of the extension plate 200 to achieve the adjustability of the air guide path.

[0097] For example, the driving member 310 may be a motor.

[0098] Combine Figure 1 As shown, on the other hand, the present application provides an air conditioner, including an air conditioner body and an air guide structure provided by any of the above embodiments.

[0099] The air guide structure has been described in detail in the above embodiments and will not be repeated here.

[0100] For example, the air conditioner body can be a ceiling-mounted air conditioner. The top of the ceiling-mounted air conditioner is installed on the ceiling, the air outlet can be opened at the bottom of the ceiling-mounted air conditioner, and the air guide plate 100 is hinged to the air outlet of the air conditioner body.

[0101] In summary, the air guide structure and air conditioner provided by the embodiment of the present application can move the extension plate 200 along the air guide direction of the air guide plate 100 through the driving action of the drive assembly 300, combined with the guiding action of the guide member 110 and the crimping member 120, thereby dynamically adjusting the length of the air guide path to adapt to different usage requirements and providing a more flexible air guide effect. This driving method ensures the smooth movement of the extension plate 200 relative to the air guide plate 100, avoiding the phenomenon of the extension plate 200 being stuck and unstable during the movement process; and by adjusting the size of the first connecting rod 320 and the second connecting rod 330, the movement range of the extension plate 200 can be changed, which is more convenient to adapt to the situation where the extension plate 200 needs to move long distances, and is relatively simple to install and maintain; there is no need to carry out complex installation design in order to replace and install a longer rack and maintain the meshing stability of the gear and rack.

[0102] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the scope of protection of the present application is obviously not limited to these specific embodiments.
