[0057] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0058] As mentioned in the background section, air handling equipment, taking air conditioning equipment as an example, typically has an air deflector at the air outlet. The air deflector is connected to the air outlet by rotation, and the airflow direction is adjusted by changing its opening angle relative to the air outlet. The airflow angle adjustment mainly relies on blades, which are generally fixed in a local area of ​​the air outlet and are pulled by a lever to achieve one-dimensional rotation, thereby achieving left-right sweeping or up-down oscillation.

[0059] However, the aforementioned adjustments to the air supply direction and angle have several drawbacks. Firstly, the area of ​​the air supply zone is directly proportional to the area of ​​the air outlet, limiting the adjustable air supply angle and resulting in a smaller air supply coverage area for the air conditioning unit, making it difficult to meet the air supply needs of large areas. Secondly, because the blades are located within the air duct and can only deflect at the same angle, blind spots can easily appear when adjusting the air supply angle, leading to significant indoor temperature differences and greatly affecting comfort.

[0060] However, the aforementioned adjustments to the air supply direction and angle have several drawbacks. Firstly, the area of ​​the air supply zone is directly proportional to the area of ​​the air outlet, limiting the adjustable air supply angle and resulting in a smaller air supply coverage area for the air conditioning unit, making it difficult to meet the air supply needs of large areas. Secondly, because the blades are located within the air duct and can only deflect at the same angle, blind spots can easily appear when adjusting the air supply angle, leading to significant indoor temperature differences and greatly affecting comfort.

[0061] To address the aforementioned issues, an air guide structure can be installed at the air outlet to control the air delivery angle, adapting to different room layouts and user needs. This helps reduce blind spots in air delivery and optimize airflow distribution.

[0062] These types of air guide structures are typically driven by an air conditioning gearbox. However, when the air conditioning gearbox drives the air guide structure to sweep air, changes in airflow can cause uneven forces on the air guide plate. This uneven force can lead to vibration of the air guide structure. Due to the uneven force, the air guide structure may experience a jerking sensation during movement. This jerking sensation not only affects the user experience but may also generate noise, increasing the operating noise level of the equipment. In extreme cases, the vibration of the air guide structure may resonate with the equipment casing, which will not only exacerbate the noise problem but may also cause the air guide structure to detach from the casing, seriously affecting the reliability and safety of the equipment.

[0063] In view of this, the embodiments of this application apply resistance to the drive gear through a damping structure, which can effectively reduce the vibration and jerking caused by uneven force, thereby reducing noise; the introduction of the damping structure can absorb and mitigate instantaneous impact force, prevent the air guide structure from resonating with the shell, and improve the stability of the system; by reducing vibration and resonance, the risk of the air guide structure falling off the shell is reduced, enhancing the reliability and safety of the equipment; the presence of the damping structure allows the air guide structure to more accurately control its movement path and speed when disturbed, helping to maintain the stability and accuracy of the air guide structure; a smoother and quieter operating state improves the user experience and reduces discomfort caused by noise and vibration.

[0064] This application provides an air handling device, which includes, but is not limited to, air conditioning equipment, humidifiers, dehumidifiers, ventilation equipment, heat recovery ventilation systems, air purifiers, and fresh air systems. In this application embodiment, an air conditioning unit is used as an example for description. Since air conditioning equipment can include wall-mounted air conditioners, floor-standing air conditioners, central air conditioners, ducted air conditioners, etc., a wall-mounted air conditioner is specifically used as an example for description below.

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0066] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. In embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0067] refer to Figures 1-5 This application provides an air conditioning gearbox, including a housing 100, a drive gear 200, an output gear 300, and a damping structure 400.

[0068] The housing 100 can be used to fix it to the mounting bracket 01.

[0069] The drive gear 200 is rotatably mounted on the housing 100. The output gear 300 meshes with the drive gear 200 and can be used to drive the base plate 02 to move relative to the mounting bracket 01.

[0070] The damping structure 400 is disposed on the housing 100 and is connected to the drive gear 200 for transmission. The damping structure 400 can apply resistance to the drive gear 200.

[0071] It is understood that the housing 100 is used to fix the mounting bracket 01, providing support and protection for the entire gearbox; the drive gear 200 can rotate inside the housing 100 and is responsible for transmitting power to the output gear 300; the output gear 300 meshes with the drive gear 200, driving the base plate 02 to move relative to the mounting bracket 01, thereby realizing the adjustment of the wind direction by the air guide structure; the damping structure 400 is set inside the housing and is connected to the drive gear 200 in a transmission manner, and can apply resistance to the drive gear; the output gear 300 is used to drive the air guide structure.

[0072] It should be noted that the base plate 02 is movably mounted on the mounting bracket 01. The base plate 02 is used to connect the air guide structure, which is used to control the air delivery angle, adapt to different room layouts and user needs, and help reduce air delivery blind spots and optimize airflow distribution. Since the specific details of the mounting bracket 01, base plate 02, and air guide structure are not within the protection scope of this application embodiment, their specific structures are not described in detail.

[0073] The resistance applied by the damping structure 400 smoothly drives the movement of the gear 200, making the air guide structure more stable during movement. The damping structure 400 alters the system's dynamic characteristics, making its response to external disturbances more stable. With appropriate damping, the system can recover to equilibrium more quickly, thus reducing vibrations caused by changes in external forces. Simultaneously, by applying resistance, the damping structure 400 reduces the system's quality factor and increases its damping ratio, thereby reducing resonance. Resonance significantly increases vibration amplitude; therefore, suppressing resonance is crucial for reducing noise and vibration.

[0074] It's important to understand that the quality factor, often simply called the Q factor, is a dimensionless parameter used to describe the damping characteristics of an oscillating system. It's a crucial indicator of a system's response characteristics near its resonant frequency. Specifically, the quality factor represents the ratio of energy loss to stored energy, or the sharpness of the system's resonance peak.

[0075] The output gear 300 is simultaneously powered, which drives the base plate 02 to move relative to the mounting bracket 01. The base plate 02 can be used to install the air guide structure.

[0076] By applying resistance to the drive gear 200 through the damping structure 400, vibration and jerking caused by uneven force can be effectively reduced, thereby reducing noise. The introduction of the damping structure 400 can absorb and mitigate instantaneous impact forces, prevent resonance between the air guide structure and the housing 100, and improve system stability. By reducing vibration and resonance, the risk of the air guide structure falling off the housing is reduced, enhancing the reliability and safety of the equipment. The presence of the damping structure 400 allows the air guide structure to more accurately control its movement path and speed when disturbed, helping to maintain the stability and accuracy of the air guide structure. A smoother and quieter operating state improves the user experience and reduces discomfort caused by noise and vibration.

[0077] In some possible implementations, the drive gear 200 is provided with a connecting gear 500, which is coaxially fixed with the drive gear 200.

[0078] The damping structure 400 includes a body and an input gear 410 connected to each other. The input gear 410 meshes with the connecting gear 500, and the body applies resistance to the connecting gear 500 through the input gear 410.

[0079] It is known that the drive gear 200 and the connecting gear 500 are coaxially fixed, and the power can be transmitted stably and efficiently. The damping structure 400 can transmit resistance to the connecting gear 500 through the input gear 410. At the same time, the drive gear 200, which is coaxial with the connecting gear 500, drives the output gear 300, thereby making the air guide structure work smoothly.

[0080] The damping structure 400 applies resistance to the connecting gear 500 through the input gear 410, effectively alleviating the vibration and jerking caused by uneven force, thereby reducing noise.

[0081] In some possible implementations, the diameter of the drive gear 200 is smaller than the diameter of the output gear 300.

[0082] The diameter of the connecting gear 500 is larger than the diameter of the driving gear 200, and the diameter of the connecting gear 500 is larger than the diameter of the input gear 410.

[0083] It can be understood that since the diameter of the connecting gear 500 is larger than that of the drive gear 200, this means that the connecting gear 500 also has more teeth than the drive gear 200. When the smaller drive gear 200 drives the larger connecting gear 500, a deceleration effect is produced, but the output torque increases. This deceleration and torque-increasing characteristic is very important for applications requiring precise control and large torque. Since the connecting gear 500 meshes with the input gear 410 and is used to transmit the resistance of the damping structure, the larger connecting gear 500 can more effectively transmit and apply damping force. The diameter of the connecting gear 500 is larger than that of the drive gear 200 and also larger than that of the input gear 410. The connecting teeth 500 can effectively transmit and amplify the motion of the drive gear 200, while applying appropriate damping through meshing with the input gear 410.

[0084] Therefore, the connecting gear 500 effectively transmits motion through its large diameter and applies damping through meshing with the input gear 410, reducing vibration and noise caused by uneven force. Through reasonable gear size design, the force transmission path is optimized, the possibility of resonance is reduced, and the stability of the system is improved.

[0085] refer to Figure 5 and Figure 6 In some possible implementations, the housing 100 is provided with a partition plate 600.

[0086] The drive gear 200 is provided with a rotating shaft 210, which passes through the partition plate 600.

[0087] The connecting gear 500 is connected to the rotating shaft 210, and the connecting gear 500 rotates relative to the housing 100 via the rotating shaft 210.

[0088] It is known that the partition 600 is used to provide additional support and stability. The partition 600 divides the internal space of the housing into different areas, which helps to organize and manage the layout of the internal components.

[0089] The partition plate 600 provides additional support, reduces the shaking of the drive gear 200 during rotation, and improves the stability of the overall structure; the connection between the rotating shaft 210 and the partition plate 600 helps to balance the force on the drive gear 200, reducing vibration and noise caused by uneven force.

[0090] In some possible implementations, the drive gear 200 faces the first surface of the partition plate 600, and the drive gear 200 and the output gear 300 are arranged on the same side relative to the partition plate 600.

[0091] The connecting gear 500 is disposed on the second surface of the partition plate 600, and the connecting gear 500 and the input gear 410 are disposed on the same side relative to the partition plate 600.

[0092] It is understood that the arrangement of the drive gear 200 and the output gear 300 ensures the directness and efficiency of power transmission, reduces intermediate transmission links, and the layout of the connecting gear 500 and the input gear 410 can work together effectively to apply appropriate damping.

[0093] The use of the partition plate 600 not only provides structural support, but also reduces the possibility of resonance and improves the stability of the system by separating gear sets with different functions; by optimizing the gear layout and damping design, it reduces the risk of the air guide structure falling off the housing, thereby enhancing the reliability and safety of the equipment. In some possible embodiments, the partition plate 600 is provided with a clearance portion 610, which accommodates the body of the damping structure 400.

[0094] It is known that the design of the clearance part 610 ensures that the damping structure 400 can be tightly integrated into the partition plate 600, reducing the space occupied and improving the compactness of the design; through a reasonable structural layout, the possibility of resonance is reduced, and the stability and reliability of the system are improved.

[0095] refer to Figures 7-9 In some possible implementations, the output gear 300 is provided with an output shaft 310, and the output shaft 310 is provided with a control element 320.

[0096] The output shaft 310 is fixed relative to the control component 320. The output shaft 310 can output torque through the control component 320, and the end of the output shaft 310 can be reused to output torque.

[0097] It should be noted that the base plate 02 is movably mounted on the mounting bracket 01. When the base plate 02 is in the first position, it is located inside the mounting bracket 01; when the base plate 02 is in the second position, at least a portion of it extends out of the mounting bracket 01. Multiple air guide vanes 03 are movably mounted on the base plate 02.

[0098] It is known that the output gear 300 is equipped with an output shaft 310, which allows the output shaft to transmit power stably; the control component 320 is relatively fixed relative to the output shaft 310, and can also output torque through the output shaft 310 to achieve precise control of the air guide structure.

[0099] It should be noted that the control component 320 is fixed on the base plate 02. In this way, when the output shaft 310 rotates, it will drive the control component 320, and the base plate 02 will rotate together with the control component 320.

[0100] Meanwhile, the output shaft 310 is fixed together with the rotation shaft of the guide vane 03, so that the guide vane 03 can also be driven by the torque output by the output shaft 310.

[0101] For example, the output gear 300 has only a half-turn gear, meaning that the gear portion of the output gear 300 only covers a 180-degree circle. This design limits the rotation range of the output shaft 310, allowing it to rotate only within a certain angular range. When the output gear 300 rotates to the end of the gear, the system stops or reverses because there is no gear to continue meshing. This reciprocating motion is ideal for applications that require periodic changes in direction. For example, the guide vane 03, which is fixed to the output shaft 310, can swing left and right; by limiting the rotation range, the half-turn gear prevents the base plate 02 and the guide vane 03 from rotating excessively, thereby avoiding damage to the mechanical structure; by limiting the range of motion, it ensures that the guide vane 03 is adjusted within a predetermined angular range, thereby achieving precise airflow control.

[0102] The fixed design of the output shaft 310 and the control component 320 ensures the precise transmission of torque, improving transmission efficiency and control accuracy. By precisely controlling the torque output, vibration and noise caused by uneven force are reduced, improving the smoothness of equipment operation. The multi-functional design of the output shaft 310 reduces the number of components, lowers system complexity, and improves overall stability.

[0103] The output shaft 310 is simultaneously powered, which drives the base plate 02 to move relative to the mounting bracket 01, thereby driving the guide vane 03 to reciprocate.

[0104] The power input device here is not limited to a motor or mechanical structure. As long as it can input power to the output gear, the embodiments of this application do not impose too many restrictions.

[0105] refer to Figure 10 In some embodiments, the partition plate 600 is fixedly connected to the rotating shaft 210. The partition plate 600 has a snap-fit ​​portion 620 with a strip-shaped hollow structure. The opening direction of the snap-fit ​​portion 620 is away from the connecting gear 500, and the opening edge of the snap-fit ​​portion 620 is arc-shaped.

[0106] The air conditioning gearbox also includes an output plate 700, which is fixed to the output shaft 310. The output plate 700 has a snap-fit ​​post 710, which can be inserted into the snap-fit ​​part 620.

[0107] Meanwhile, the output gear 300 is sleeved on the output shaft 310.

[0108] It is understood that the output shaft 310 is used to output power. When the output shaft 310 rotates, it drives the output disk 700 to rotate. At this time, the locking pin 710 rotates together with the output disk. When the locking pin 710 moves to the opening of the locking part 620, the locking pin 710 slides into the locking part 620. At this time, the partition plate 600 rotates with the locking pin 710. The partition plate 600 drives the drive gear 200 on the rotating shaft 210 to rotate, and the drive gear 200 drives the 300 to rotate.

[0109] Due to the structural limitations of the locking part 620, as the moving output disk 700 continues to rotate, the locking post 710 will disengage from the locking part 620, and the partition plate 600 will stop driving the drive gear 200 on the rotating shaft 210 to rotate, thereby stopping the drive gear 200 from driving the output gear 300 to rotate, thus realizing the reciprocating staged movement of the workpiece controlled on the output gear 300.

[0110] In some possible implementations, the output gear 300 is provided with a fixing groove 330, and the control member 320 is provided with a mounting part 321, which is disposed within the fixing groove 330.

[0111] Understandably, the output gear 300 is provided with a fixing groove 330 for accommodating and fixing the mounting part 321 of the control component 320. The design of the fixing groove 330 ensures that the control component 320 can be firmly connected to the output gear 300, providing reliable support, while achieving precise torque transmission.

[0112] In some embodiments, the mounting portion 321 may be a mounting protrusion or a mounting groove, which can match the corresponding shape on the fixing groove 330.

[0113] By providing a fixing groove 330 on the output gear 300, the mounting part 321 of the control component 320 can be securely embedded therein, improving the stability of the connection and reducing vibration caused by loosening; the tight fit between the mounting part 321 and the fixing groove 330 ensures accurate torque transmission, reduces energy loss during transmission, and improves system efficiency; the stable connection reduces noise and vibration caused by loose or unstable connections, and improves the smoothness of equipment operation.

[0114] This application provides an indoor unit, which is a wall-mounted air conditioner, and the wall-mounted air conditioner includes the aforementioned air conditioner gearbox.

[0115] It is important to know that the evaporator, condenser, and compressor are the core components of refrigeration equipment, and they work together to achieve the refrigeration cycle.

[0116] The evaporator is the component in a refrigeration system responsible for absorbing heat. In the evaporator, liquid refrigerant absorbs heat from the surrounding air and evaporates into a gas. This process lowers the temperature of the surrounding air, thus achieving a cooling effect.

[0117] The condenser is the component in a refrigeration system responsible for releasing heat. In the condenser, the gaseous refrigerant releases heat and condenses into a liquid, a process that releases heat into the external environment.

[0118] The compressor is responsible for compressing the refrigerant and driving its circulation in the system. It compresses the low-pressure gaseous refrigerant into a high-pressure gaseous state, thereby increasing its temperature and pressure.

[0119] This application provides an air handling device, including the indoor unit described above, or the air conditioning gearbox described above.

[0120] This application provides an air handling device, which includes, but is not limited to, air conditioning equipment, humidifiers, dehumidifiers, ventilation equipment, heat recovery ventilation systems, air purifiers, and fresh air systems. In this application embodiment, an air conditioning unit is used as an example for description. Air conditioning equipment may include wall-mounted air conditioners, floor-standing air conditioners, central air conditioning systems, ducted air conditioners, etc.
