Therefore, they should not be construed as limitations on this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] As a core component of the vehicle's air conditioning system, the air vent adjustment device's main function is to precisely adjust the airflow volume and direction of the vents to ensure uniform air circulation inside the vehicle and passenger comfort. The air vent adjustment device uses an air vent adjustment actuator to drive the air damper; by adjusting the angle of the damper, the airflow volume and direction are adjusted.

[0039] As the power core of an air vent regulation device, the vent actuator is a key component. Currently, vent actuators generally suffer from large size and space consumption. This problem is particularly pronounced in situations with limited space or complex installation environments, restricting the design of the air vent regulation device. For example, they are typically installed on one side of the fan casing, resulting in a large overall space occupation. The size and weight of the actuator not only affect the installation and layout of the overall system but may also increase energy consumption and maintenance difficulty. Therefore, there is an urgent need to optimize existing vent actuators to improve their space utilization efficiency and performance.

[0040] Please see Figure 1 The air vent regulating actuator 10 provided in the embodiments of this application will now be described. The air vent regulating actuator 10 includes:

[0041] Output shaft 3; Output shaft 3 is used to output the driving force for adjusting the air outlet;

[0042] Transmission mechanism 2; Transmission mechanism 2 includes at least two stages of transmission structure connected in sequence, and output shaft 3 is connected to transmission mechanism 2 in transmission.

[0043] Drive component 1; Drive component 1 is connected to transmission mechanism 2.

[0044] The drive unit 1 and the transmission mechanism 2 are located on the side of the output shaft 3, and each stage of the transmission structure is arranged along the axial direction of the output shaft 3.

[0045] In the vent adjustment actuator 10 of this embodiment, the drive component 1 is the power source of the actuator. The drive component 1 can be driven by different types of motors, such as electric, pneumatic, or hydraulic motors, with electric motors being the most common. The motor can provide power by connecting to the connection port through its terminal wires. The function of the transmission mechanism 2 is to effectively transmit the power of the drive component 1 to the output shaft 3. Its structure includes at least two stages of transmission. Given that vent adjustment operations often require high torque and low speed, these transmission structures are generally designed as reduction gear transmission structures and can be combined with mechanisms that can change the transmission direction as needed. The purpose of setting at least two stages of transmission structure is to provide flexibility in arranging the reduction gear transmission structure, thereby ensuring that the required higher torque can be obtained during vent adjustment. The specific number of transmission stages of the transmission mechanism 2 is determined according to the actual application requirements. The transmission mechanism 2 is connected to the drive component 1, so that the power of the drive component 1 is transmitted to the transmission mechanism 2, and then transmitted step by step between the various stages of the transmission structure before being transmitted to the output shaft 3. Output shaft 3 is the power output structure of air outlet regulating actuator 10, used to output the driving force for air outlet regulation. It is connected to the damper to drive the damper to achieve air outlet regulation.

[0046] In this embodiment, the drive component 1 and the transmission mechanism 2 are located on the side of the output shaft 3, which can effectively reduce the axial dimension of the vent regulating actuator 10 on the output shaft 3. Simultaneously, the various stages of the transmission structure are arranged sequentially along the axial direction of the output shaft 3, which can effectively reduce the radial dimension of the vent regulating actuator 10 on the output shaft 3. Therefore, the vent regulating actuator 10 in this embodiment can balance both axial and radial dimensions, improving structural compactness, reducing overall volume, and thus reducing space occupation. The vent regulating actuator 10 is smaller in size and requires less installation space, and is not limited to installation on the fan casing; it can be installed on the vent body 20, thereby reducing the overall volume of the vent structure.

[0047] Please see Figure 1 In some embodiments of this application, the output shaft 3 includes a first output end 31 and a second output end 32, with the drive member 1 and the transmission mechanism 2 both located between the first output end 31 and the second output end 32. Since the transmission mechanism 2 is located on the side of the output shaft 3, it is more suitable for air vent adjustment actuators 10 with relatively long output shafts 3. In this embodiment, the output shaft 3 includes a first output end 31 and a second output end 32, which can be connected to both sides of the damper respectively, allowing for synchronous drive of the damper and ensuring balanced force on both sides of the damper.

[0048] Since the first output end 31 and the second output end 32 are used to drive the two sides of the damper respectively, the distance between them is usually adapted to the width of the air outlet. This distance is sufficient to arrange the drive element 1 and the transmission mechanism 2. Therefore, in this embodiment, the drive element 1 and the transmission mechanism 2 are both located between the first output end 31 and the second output end 32, thereby ensuring the compactness of the air outlet regulating actuator 10. The axial length of the entire air outlet regulating actuator 10 on the output shaft 3 is equivalent to the distance between the first output end 31 and the second output end 32. At the same time, since the various stages of the transmission structure in the transmission mechanism 2 are arranged sequentially along the axial direction of the output shaft 3, the radial dimension of the air outlet regulating actuator 10 on the output shaft 3 is also reduced to the greatest extent, thereby minimizing the overall volume of the air outlet regulating actuator 10.

[0049] Please see Figure 1 In some embodiments of this application, the air vent regulating actuator 10 further includes a housing 4, a driving member 1 and a transmission mechanism 2 disposed within the housing 4; an output shaft 3 disposed within the housing 4, a first output end 31 and a second output end 32 extending out of the housing 4 respectively, a first bearing 41 and a second bearing 42 disposed on the housing 4, and the two ends of the output shaft 3 respectively disposed within the first bearing 41 and the second bearing 42.

[0050] In this embodiment, the air vent regulating actuator 10 also includes a housing 4, which is the external protective structure of the actuator. The housing 4 houses the drive component 1, the transmission mechanism 2, and the output shaft 3, preventing external dust, moisture, and other impurities from entering the interior, while providing necessary support and protection. The shape of the housing 4 can be determined based on the layout of the air vent regulating actuator 10 itself and specific installation requirements.

[0051] The drive component 1 and transmission mechanism 2 are housed within the housing 4, which protects them. The output shaft 3 is also housed within the housing 4, while the first output end 31 and the second output end 32 extend out of the housing 4 to connect to the damper and drive it. A first bearing 41 and a second bearing 42 are respectively positioned on the housing 4 near the first output end 31 and the second output end 32. These bearings support the output shaft 3, ensuring its stability and accuracy during rotation and preventing deviation. This guarantees the concentricity of the first output end 31 and the second output end 32, thus ensuring the synchronicity of the drive on both sides of the damper. In addition to supporting the output shaft 3, the drive component 1 and transmission mechanism 2 can also be mounted on the housing 4, ensuring operational stability.

[0052] Please see Figure 2 and Figure 3 In some embodiments of this application, the transmission mechanism 2 includes at least one double-geared member, which comprises two interconnected gear transmission mechanisms 2, and the two gear transmission mechanisms 2 of the at least one double-geared member are respectively located on both sides of the output shaft 3.

[0053] There are many ways to specifically arrange the driving component 1 and the transmission mechanism 2. In this embodiment, the transmission mechanism 2 includes at least one double-geared component. The double-geared component is a structure formed by connecting two gear transmission mechanisms 2. When one gear transmission mechanism 2 rotates, it can synchronously drive the rotation of the other gear transmission mechanism 2. For example, two gears can be connected in double gears, or a gear and a worm can be connected in double gears. The double-geared component can achieve different transmission ratio changes by adjusting the number of teeth and the module, thereby adjusting the torque and speed output by the actuator to meet the output requirements of the actuator. In this embodiment, the transmission mechanism 2 includes at least one double-geared component, and one double-geared component can serve as a primary transmission structure. In these double-geared components, the two gear transmission mechanisms 2 of at least one double-geared component are located on both sides of the output shaft 3, that is, the output shaft 3 is clamped between the two gear transmission mechanisms 2 of the double-geared component, so that the gear transmission mechanisms 2 form a structure with staggered arrangement on both sides, which allows the output shaft 3 and the double-geared component to be arranged more compactly, thereby reducing the size of the actuator. The total number of double-geared components and the number of double-geared components distributed on both sides of the output shaft 3 are designed according to actual needs. For example, if only one double-geared component is needed in the transmission mechanism 2, then the two gear transmission mechanisms 2 of this double-geared component can be placed on both sides of the output shaft 3; or, if the transmission mechanism 2 contains multiple double-geared components, then two gear transmission mechanisms 2 of one or more double-geared components can be placed on both sides of the output shaft 3. Figure 2 In the embodiment shown, the transmission mechanism 2 is provided with a total of six transmission structures, of which the middle second to fifth transmission structures are all double gears. In these double gears, the gear transmission mechanisms 2 of the second and third transmission structures are respectively arranged on both sides of the output shaft 3.

[0054] Please see Figure 3 In some embodiments of this application, the axial direction of the output end of the drive member 1 is parallel to the axial direction of the output shaft 3, and the axial direction of the double gear is perpendicular to the axial direction of the output shaft 3.

[0055] The transmission mechanism 2 includes a first worm 21, which is disposed on the output end of the drive member 1. The double gear includes a first double gear 22, which includes a first helical gear 221. The first worm 21 meshes with the first helical gear 221.

[0056] To facilitate the placement of the two gear transmission mechanisms 2 of the double gear assembly on opposite sides of the output shaft 3, the axial direction of the double gear assembly can be perpendicular to the axial direction of the output shaft 3. If the axial direction of the output end of the drive member 1 is parallel to the axial direction of the output shaft 3, then the axial direction of the double gear assembly is perpendicular to the axial direction of the output end of the drive member 1, achieving transmission between them. In this embodiment, the transmission mechanism 2 includes a first worm gear 21, which is disposed on the output end of the drive member 1. Here, the first worm gear 21 serves as the first-stage transmission structure, used to transmit power from the output end of the drive member 1. Placing the first worm gear 21 on the output end of the drive member 1 achieves stable transmission while occupying less space. The double gear assembly includes a first double gear assembly 22, which includes a first helical gear 221. The first double gear assembly 22 is used to connect with the first worm gear 21 to achieve transmission. Specifically, the first helical gear 221 in the first double gear assembly 22 meshes with the first worm gear 21 to form a worm gear transmission structure.

[0057] It is important to note that power is transmitted from the first worm gear 21 to the first helical gear 221. Due to the irreversible nature of the worm gear transmission structure, the helical gear can only be driven by the worm, not by the helical gear, or a very large torque is required for the helical gear to drive the worm. Therefore, in this embodiment, the first double-geared member 22 can be easily driven by the drive component 1, thereby driving the output shaft 3 to rotate and adjusting the damper. When the actuator is powered off, it has a certain holding force, which can achieve self-locking of the actuator and prevent the first worm gear 21 in the transmission mechanism 2 from being driven in reverse under the gravity or vibration of the damper when the power is off, thus preventing the damper from closing or shifting. In addition, the use of worm gear transmission also has better noise performance.

[0058] Please see Figure 3 In some embodiments of this application, the axial direction of the double gear is perpendicular to the axial direction of the output shaft 3; the transmission mechanism 2 includes a second helical gear 24, which is disposed on the output shaft 3; the double gear includes a second double gear 23, which includes a second worm 231, which meshes with the second helical gear 24.

[0059] The function of the second helical gear 24 in the transmission mechanism 2 is to transmit power from the transmission mechanism 2 to the output shaft 3. The second helical gear 24 is mounted on the output shaft 3, enabling stable transmission while occupying minimal space. Furthermore, the axial direction of the second helical gear 2 is the same as that of the output shaft 3. To facilitate the arrangement of the two gear transmission mechanisms 2 on opposite sides of the output shaft 3, the axial direction of the double gear is perpendicular to the axial direction of the output shaft 3. This ensures that the axial direction of the double gear is perpendicular to the axial direction of the second helical gear 24.

[0060] Therefore, in this embodiment, a second worm gear 231 is provided in the second double-geared member 23 of the double-geared member. The second worm gear 231 meshes with the second helical gear 24, thereby transmitting power from the second double-geared member 23 to the second helical gear 24, which in turn drives the output to rotate. Similarly, the second worm gear 231 and the second helical gear 24 also form a worm gear transmission structure, which can achieve self-locking when the actuator is powered off, thereby preventing the damper from closing or shifting. This is suitable for damper structures that require hovering after power failure and has better noise performance.

[0061] In the two embodiments described above, in addition to the first double-gear component 22 and the second double-gear component 23, one or more other double-gear components can be provided. The gear transmission mechanism 2 of these double-gear components can be either spur gear or helical gear. The double-gear components mesh sequentially along the output shaft 3, which not only reduces the size but also achieves the effects of increasing torque, reducing speed, and reducing noise.

[0062] Please see Figure 4 and Figure 5 In some embodiments of this application, the axial direction of the output end of the drive member 1 is parallel to the axial direction of the output shaft 3. The transmission mechanism 2 includes a planetary transmission structure 25, a first gear 26, and a second gear 27. The planetary transmission structure 25 is arranged along the axial direction of the output shaft 3. The planetary transmission structure 25 is connected to the output end of the drive member 1. The first gear 26 is disposed on the output end of the planetary transmission structure 25, and the second gear 27 is disposed on the output shaft 3. The first gear 26 and the second gear 27 mesh with each other.

[0063] In this embodiment, the air vent regulating actuator 10 achieves transmission and torque adjustment through a planetary transmission structure 25. To reduce the size of the actuator, the planetary transmission structure 25 is also arranged along the output shaft 3, and the axial direction of the output end of the drive member 1 is parallel to the axial direction of the output shaft 3, allowing the output end of the drive member 1 to be directly connected to the planetary transmission structure 25. When the air vent regulating actuator 10 is de-energized, when the gravity or vibration force of the damper is transmitted to the output end of the planetary transmission structure 25, the planetary transmission structure 25 can generate a certain counter-drive force, thereby preventing the damper from closing or shifting. The planetary transmission structure 25 is arranged along the axial direction of the output shaft 3, and its output end can also be parallel to the output shaft 3. The first gear 26 is disposed on the output end of the planetary transmission structure 25, and the second gear 27 is disposed on the output shaft 3. The first gear 26 and the second gear 27 mesh to achieve parallel transmission. The planetary transmission structure 25 can adopt a multi-stage planetary structure. For specific details, refer to existing planetary transmission structures 25, such as the planetary transmission structure 25 disclosed in patent document CN201843951U.

[0064] Please see Figure 6 and Figure 7In some embodiments of this application, the axial direction of the output end of the drive member 1 is perpendicular to the axial direction of the output shaft 3, and the transmission mechanism 2 includes at least two stages of parallel transmission structure 28, the axial direction of the parallel transmission structure 28 being parallel to the axial direction of the output end of the drive member 1.

[0065] The axial direction of the output end of the drive component 1 can be perpendicular to or parallel to the axial direction of the output shaft 3. In this embodiment, the axial direction of the output end of the drive component 1 is perpendicular to the axial direction of the output shaft 3, thus enabling parallel transmission with the transmission mechanism 2. The transmission mechanism 2 includes at least two stages of parallel transmission structures 28. The first stage transmission structure can be directly mounted on the output shaft 3 of the drive component 1, and the remaining transmission structures can be arranged sequentially. The parallel transmission structure 28 can be a gear or a double-gear structure, etc.

[0066] The axial direction of the parallel transmission structure 28 is parallel to the axial direction of the output end of the drive member 1. Multiple parallel transmission structures 28 have parallel axes, enabling multi-stage parallel transmission. The axial direction of the parallel transmission structure 28 is perpendicular to the axial direction of the output shaft 3, allowing for a more compact arrangement of the transmission structure. Please refer to [link / reference]. Figure 7 Taking a double-gear transmission as an example, when the axial direction of the double-gear is perpendicular to the axial direction of the output shaft 3, the maximum lateral dimension of the vent regulating actuator 10 is approximately equal to the maximum diameter of the double-gear. However, if the axial direction of the double-gear is parallel to the axial direction of the output shaft 3, the maximum lateral dimension of the vent regulating actuator 10 needs to be greater than the sum of the diameter of the output shaft 3 and the maximum diameter of the double-gear. Therefore, having the axial direction of the parallel transmission structure 28 perpendicular to the axial direction of the output shaft 3 can significantly reduce the lateral dimension of the vent regulating actuator 10. Furthermore, the arrangement of each stage of the parallel transmission structure 28 along the output shaft 3 is also very simple. Therefore, the transmission mechanism 2 in this embodiment is simpler to arrange and easier to assemble.

[0067] Please see Figure 7 In some embodiments of this application, the transmission mechanism 2 further includes a third helical gear 29, which is disposed on the output shaft 3, and the parallel transmission structure 28 includes a third worm gear 281, which meshes with the third helical gear 29.

[0068] Because the axial direction of the parallel transmission structure 28 is perpendicular to the axial direction of the output shaft 3, a third helical gear 29 is installed on the output shaft 3 to achieve transmission between the parallel transmission structure 28 and the output shaft 3. A third worm gear 281 is installed in the parallel transmission structure 28, and transmission is achieved through the meshing of the third worm gear 281 and the third helical gear 29. The third worm gear 281 and the third helical gear 29 form a worm gear transmission structure, which can achieve self-locking when the actuator is powered off, thereby preventing the damper from closing or shifting. It is suitable for damper structures that require power-off hovering and has better noise performance.

[0069] In the above embodiments, the number of transmission stages of the transmission mechanism 2 is determined according to requirements, for example, Figures 1 to 3 In the illustrated embodiment, the transmission mechanism 2 has six stages of rotation. The first stage transmission structure is a first worm 21 connected to the output end of the drive member 1. The second stage transmission structure is a first double-geared member 22, which includes a first helical gear 221. The first worm 21 and the first helical gear 221 are connected to form a worm structure. The other gear in the first double-geared member 22 can be either a helical gear or a spur gear. The third and fourth stage transmission structures are both double-geared members, specifically helical or spur gears. The fifth stage transmission structure includes a second worm 231 and another gear, where the other gear meshes with the fourth stage transmission structure, and the second worm 231 is used to transmit power to the next stage transmission structure. The sixth and final stage transmission structure is a second helical gear 24 mounted on the output shaft 3, which meshes with the second worm 231 to achieve transmission. For example... Figures 4 to 5 In the illustrated embodiment, the transmission mechanism 2 includes a planetary transmission structure, a first gear 26, and a second gear 27 connected in sequence. The first gear 26 is located on the output end of the planetary transmission structure 25, and the second gear 27 is located on the output shaft 3. For example... Figures 6 to 7 In the embodiment shown, the transmission mechanism 2 includes a multi-stage parallel transmission structure 28 and a third helical gear 29 disposed on the output shaft 3. Except for the gear installed on the output end of the drive member 1, the other parallel transmission structures 28 are all double gear members. The last stage of double gear members includes a third worm 281, which meshes with the third helical gear 29 to realize the transmission between the transmission mechanism 2 and the output shaft 3.

[0070] Based on the air vent regulating actuator 10 in the above embodiments, this application also provides an air vent structure that uses the air vent regulating actuator 10 in the above embodiments. Since the air vent regulating actuator 10 has the advantage of small size, it is beneficial to reduce the size of the air vent and facilitate its arrangement. In addition to its small size, the air vent regulating actuator 10 also has advantages such as power-off self-locking, large transmission ratio, large output torque, better noise performance, and synchronous output at both ends, all of which contribute to improving the performance of the air vent structure.

[0071] Please see Figure 8 In some embodiments of this application, the air vent structure includes an air vent body 20, and an air vent adjustment actuator 10 is disposed on the inner side of the air vent body 20.

[0072] Taking the air vent structure of a car as an example, the existing air vent adjustment actuator 10 is usually installed on the outside of the fan. For left-hand drive and right-hand drive cars, completely mirror-image parts are required, resulting in high mold costs and a large variety of materials, which is inconvenient for material management. However, the air vent adjustment actuator 10 in this embodiment is small in size and can be directly installed on the air vent body 20. The air vent body 20 is the structure with the air vent. Installing the air vent adjustment actuator 10 on the inside of the air vent body 20 can save space on the fan cover, thereby reducing the overall volume. Moreover, the same air vent structure can be used in left-hand drive and right-hand drive cars, thus reducing the variety of materials, improving material versatility, facilitating material management, and reducing mold costs.

[0073] Please see Figure 8 In some embodiments of this application, the air vent structure further includes a stacking door mechanism 30. The first output end 31 and the second output end 32 of the air vent regulating actuator 10 are respectively connected to both sides of the stacking door mechanism 30 to synchronously drive the stacking door mechanism 30.

[0074] The drive unit 1 is powered by an external circuit or other structure, which drives the transmission mechanism 2 to rotate. The transmission mechanism 2 then drives the output shaft 3 to rotate. The actuator is integrated inside the damper and is connected to the damper via a shaft, causing the damper to rotate and thus opening, closing, and adjusting the opening degree of the stacking door mechanism 30. The stacking door mechanism 30 itself has a small size, which facilitates the placement of the vent adjustment actuator 10 on the vent body 20. The first output end 31 and the second output end 32 of the vent adjustment actuator 10 are respectively connected to both sides of the stacking door mechanism 30, allowing for synchronous driving of the stacking door mechanism 30. This ensures force balance at both ends of the stacking door mechanism 30 and improves the service life of the vent structure.

[0075] The aforementioned air vent adjustment actuator and air vent structure can be used in ventilation, air conditioning and other systems, which can reduce the space occupied by the air vent adjustment actuator and air vent structure, thereby facilitating the arrangement of various parts and the overall design.

[0076] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
