Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle interior technology, and in particular to an air vent structure and a vehicle. Background Technology
[0002] Currently, air conditioning systems have become an indispensable component of vehicles, ensuring the comfort of passengers. Air vents, as the terminal components of the air conditioning system, are located inside the vehicle body, introducing heated or cooled air or fresh air from outside into the vehicle's interior.
[0003] Existing air outlet structures typically include an air outlet housing, a fan ball installed inside the housing, and a damper assembly. A transmission mechanism is provided between the fan ball and the damper assembly. The fan ball can rotate relative to the air outlet housing, and the opening and closing of the damper assembly is controlled by the transmission mechanism to adjust the air volume.
[0004] However, after long-term use, the transmission mechanism of the existing air outlet structure is prone to failure or malfunction, which leads to the failure of the damper assembly to open and close, resulting in failure of air volume regulation and affecting the user experience. Utility Model Content
[0005] This application addresses, to at least some extent, one of the technical problems in the related art.
[0006] Therefore, this application aims to provide an air outlet structure and vehicle, which improves the reliability and structural stability of the damper assembly drive by improving the transmission mechanism between the air guide assembly and the damper assembly, thereby improving the response accuracy and driving comfort of the air conditioning system.
[0007] To achieve the above objectives, in a first aspect, this application provides an air outlet structure, comprising: an air outlet housing, an air guide assembly, an air damper assembly, and a drive shaft; the air outlet housing includes an air inlet and an air outlet that are disposed opposite to and communicate with each other; the air guide assembly is disposed at the air outlet of the air outlet housing, and the air guide assembly includes air guide blades and a drive seat that is synchronously rotatably connected to the air guide blades, the drive seat having an opening on the side away from the air guide blades and forming a rotating cavity inside; the air damper assembly is disposed inside the air outlet housing and close to the air inlet; the drive shaft is disposed between the air guide assembly and the air damper assembly, and a rotating part is provided at the end of the drive shaft near the air guide assembly, the rotating part being rotatably disposed in the rotating cavity, and the end of the drive shaft away from the rotating part being drively connected to the air damper assembly; wherein, a drive part is protruding on the surface of the rotating part that mates with the rotating cavity, and a guide part is formed on the inner surface of the rotating cavity, the guide part being able to be inserted into the drive part and transmitting the rotation of the drive seat to the drive shaft.
[0008] In the above technical solution, a transmission part and a guide part that cooperate with each other are set between the rotating cavity and the rotating part to reliably transmit the rotation of the air guide blades to the transmission shaft, thereby driving the damper assembly to open and close, realizing the adjustment of the air volume, improving the reliability and structural stability of the damper assembly during the driving process, thereby ensuring the accuracy of the air volume adjustment, improving the response efficiency of the vehicle air conditioning system and the driving comfort.
[0009] In some embodiments, the rotating part and the rotating cavity form a multi-degree-of-freedom rotational fit so that the air guide vane can rotate in multiple directions relative to the air outlet housing; the guide part extends from the end of the transmission seat near the air guide vane to the opening end of the transmission seat, and the width of the guide part is adapted to the size of the transmission part so as to transmit the rotation of the transmission seat along the circumference of the air guide vane to the transmission shaft.
[0010] In the above technical solution, the rotating part at one end of the drive shaft and the rotating cavity of the air guide assembly form a multi-degree-of-freedom rotational fit, enabling the air guide blades to rotate flexibly in multiple directions and realize the adjustment of the air outlet direction; in addition, the guide part has a certain extension length and the width is adapted to the size of the drive part, so as to ensure the circumferential transmission effect without affecting the adjustment of the air outlet direction of the air guide blades.
[0011] In some embodiments, the guide vane includes a plurality of blade bodies and an inner ring seat located at the center of the plurality of blade bodies, wherein a mounting cavity is defined in the inner ring seat and the mounting cavity is open on the side facing the drive shaft, and a drive seat is mounted in the inner ring seat.
[0012] In the above technical solution, the inner ring seat on the guide vane provides an installation position for the transmission seat. This effectively utilizes the structure of the guide vane to house the transmission seat within the mounting cavity of the inner ring seat, reducing the axial length of the air outlet structure. Furthermore, the transmission seat's location within the inner ring seat also protects it from external impacts that could cause functional failure, thus improving the reliability of the transmission.
[0013] In some embodiments, the air vent housing includes an outer shell and a positioning part fixed inside the outer shell. The positioning part is a cylindrical structure extending axially along the outer shell. The positioning part is for inserting a drive shaft to position the drive shaft. A portion of the sidewall at one end of the positioning part protrudes axially relative to another portion of the sidewall to form a limiting step at the connection point, defining a limiting area between the two limiting steps. A rotation limiting part is circumferentially protruding on the drive shaft. The circumferential length of the rotation limiting part is less than the circumferential length of the limiting area. The rotation limiting part is located within the limiting area to limit the rotation range of the drive shaft.
[0014] In the above technical solution, the positioning part itself forms a limiting area, which cooperates with the rotation limiting part set on the transmission shaft to limit the rotation range of the transmission shaft. This avoids the problem of not being able to perceive the rotation angle during the adjustment of the air volume. The range of the limiting area can correspond to the opening and closing stroke of the damper assembly, so that the user can effectively perceive the degree of air volume adjustment and adjust it to the required air volume.
[0015] In some embodiments, the air outlet housing is provided with a receiving chamber, and the interior of the drive shaft and the rotating part is hollow; the air outlet structure also includes a light-emitting component, which includes a light-emitting body and an electrical connector electrically connected to the light-emitting body; the electrical connector is disposed in the receiving chamber, and the light-emitting body extends from the electrical connector through the interior of the drive shaft to the rotating part; the rotating part, the drive seat, and the inner ring seat are respectively formed with light-transmitting parts corresponding to the light-emitting body, and the light-transmitting parts are used to allow light emitted by the light-emitting body to pass through.
[0016] In the above technical solution, a light-emitting component is integrated into the air outlet structure. The light-emitting component emits light, which can indicate the location of the air outlet and enhance the aesthetics of the interior. The drive shaft is designed as a hollow structure, and the light-emitting body is installed in the internal space of the drive shaft and the air outlet housing, providing sufficient installation space for the light-emitting body. Various types of light bodies can be selected as needed.
[0017] In some embodiments, a light-transmitting cover is mounted on the side of the inner ring seat away from the drive shaft, and the light-transmitting cover is used to display optical patterns.
[0018] In the above technical solution, the design of the light-transmitting cover allows the light emitted by the light source to form an optical pattern with decorative effect under the refraction or diffuse reflection of the light-transmitting cover, thereby enhancing the atmosphere in the driver's cabin and increasing the personalization of the interior.
[0019] In some embodiments, light-transmitting openings are formed on the rotating part, the transmission seat, and the inner ring seat respectively corresponding to the light-emitting element, and multiple light-transmitting openings form a light-transmitting channel extending from the outside of the inner ring seat into the rotating part; the light-transmitting cover includes a light-transmitting end cap and a light-guiding part; the light-transmitting end cap is installed on the inner ring seat and covers the end face of the inner ring seat; the light-guiding part is located on the side of the light-transmitting end cap facing the inner ring seat, and the light-guiding part extends into the rotating part through the light-transmitting channel, opposite to the end of the light-emitting element.
[0020] In the above technical solution, the light-transmitting end cap of the photomask covers the end face of the inner ring seat, and the light guide extends into the light-transmitting channel opposite to the light-emitting body, effectively guiding the light emitted by the light-emitting body to the light-transmitting end cap, thereby collecting the light and transmitting it to the user through the light-transmitting end cap, enhancing the uniformity and brightness of the light.
[0021] In some embodiments, the end of the inner ring seat away from the light-transmitting end cap extends outward relative to the side wall of the inner ring seat to form a limiting boss; a knob ring is sleeved on the outer periphery of the inner ring seat, and the knob ring is limited between the light-transmitting end cap and the limiting boss; a linkage part is protruding on the inner surface of the knob ring, and a mating part for inserting the linkage part is provided on the side wall of the inner ring seat, so as to drive the air guide blade to rotate by rotating the knob ring.
[0022] In the above technical solution, the knob ring is installed using a light-transmitting cover and an inner ring seat. A reliable linkage between the knob ring and the inner ring seat is achieved through a linkage mechanism and a mating mechanism. When the user rotates the knob ring, the linkage mechanism rotates accordingly, driving the mating mechanism, which in turn causes the air guide vanes to rotate synchronously, thus adjusting the airflow direction or volume.
[0023] In some embodiments, a transmission gear is mounted on the end of the transmission shaft away from the rotating part, and the transmission gear is located between the positioning part and the damper assembly; the surface of the transmission gear facing away from the transmission shaft is a tooth surface, which is connected to the damper assembly in a transmission manner; the surface of the transmission gear facing the transmission shaft is a positioning surface, and a positioning groove is provided on the positioning surface; an installation groove is provided in the side wall of the positioning part, the opening of the installation groove is facing the positioning surface, a positioning member is installed in the installation groove, an elastic member is provided between the positioning member and the bottom of the installation groove, one end of the positioning member extends out of the installation groove and makes pressure contact with the positioning surface under the action of the elastic member; the transmission gear is driven to rotate by the transmission shaft, and the positioning member slides on the positioning surface, and the positioning groove is located on the sliding path of the positioning member; the damper assembly is configured such that when the positioning member slides into the positioning groove, the damper assembly is in a fully open or fully closed state.
[0024] In the above technical solution, the positioning of the damper's open / closed state can be achieved through the design of the positioning component and the positioning groove. The circumferential rotation of the guide vanes, in conjunction with the transmission and guiding components, causes the transmission shaft to rotate, driving the transmission gear to rotate. As the transmission gear rotates, when the positioning component slides into the positioning groove, the elastic component strikes the bottom of the groove, producing a crisp sound to indicate that the opening / closing position is achieved. As rotation continues, the resistance of the elastic component must be overcome, causing the positioning component to slide out of the positioning groove, thus transmitting the resistance to the user and allowing the user to perceive the rotational position.
[0025] In a second aspect, this application provides a vehicle, including a body, with a passenger space defined inside the body, and an air vent structure as described in any of the first aspects above provided within the passenger space.
[0026] In the above technical solution, the vehicle interior is equipped with an improved air vent structure, which makes the adjustment of the air conditioning air direction and air volume more reliable, improves the accuracy of the vehicle air conditioning system response, and thus improves the physical comfort of the driver and passengers.
[0027] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0061] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.
[0062] In vehicle air conditioning systems, air vents, as key components for air delivery and airflow regulation, are widely placed in various locations within the vehicle's passenger space (such as the center console, both sides of the dashboard, and the rear seat area). As the final actuator of the air conditioning system for transmitting airflow, the air vents are responsible for effectively guiding cold / hot air to various areas of the vehicle, directly affecting user comfort and driving experience.
[0063] Existing air outlet structures typically include an air outlet housing, a fan that can rotate relative to the housing to adjust the airflow direction, and a damper assembly for controlling the airflow volume. To achieve airflow volume regulation, a transmission mechanism is also provided between the fan and the damper assembly, which drives the damper assembly to open or close by rotating the fan.
[0064] However, after long-term use, the transmission mechanism of this type of structure is prone to mechanical fatigue or wear, which can lead to the damper assembly failing to respond accurately to control commands, resulting in problems such as poor opening or failure to close, causing the air volume regulation to fail, reducing the user experience and the reliability of the system.
[0065] Based on this, this application proposes an air outlet structure and a vehicle. By structurally improving the transmission mechanism between the air guide assembly and the damper assembly, the reliability and structural stability of the damper assembly drive are improved. This effectively avoids the problem of the damper failing to open or close due to transmission mechanism failure, thereby ensuring the accuracy of air volume adjustment and improving the response accuracy of the air conditioning system and the driving comfort.
[0066] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.
[0067] like Figures 1 to 5 As shown in the schematic embodiment of the air outlet structure provided in this application, the air outlet structure includes: an air outlet housing 1, an air guide assembly 2, and an air damper assembly 3.
[0068] The air vent housing 1 includes an air inlet 101 and an air outlet 102 that are arranged opposite to each other and connected. An air intake channel is formed inside the air vent housing 1 between the air inlet 101 and the air outlet 102. The airflow in the air conditioning system enters the air intake channel through the air inlet 101 and flows out through the damper assembly 3, the air outlet 102 and the air guide assembly 2.
[0069] The air guide assembly 2 is located at the air outlet 102 of the air outlet housing 1, and the air guide assembly 2 includes air guide blades 21. The air guide blades 21 are used to guide the outflow direction of the airflow, and the user can control the outflow direction by adjusting the angle of the air guide blades 21.
[0070] The damper assembly 3 is located inside the air outlet housing 1 and near the air inlet 101. By controlling the opening and closing degree of the damper assembly 3, the flow of air and the volume of air output can be adjusted.
[0071] like Figures 22-24 As shown, the damper assembly 3 includes a first damper 31 and a second damper 32, with one side of the first damper 31 and one side of the second damper 32 rotatably connected to each other.
[0072] By driving the first damper 31 and the second damper 32 to rotate close to each other around the rotation axis, the opening of the air inlet channel at this position gradually increases, and the air volume gradually increases; when the first damper 31 and the second damper 32 are parallel to each other or close together, the damper assembly 3 is in a fully open state, the opening of the air inlet channel reaches its maximum, and the air volume is at its maximum.
[0073] By driving the first damper 31 and the second damper 32 to rotate away from each other around the rotation axis, the opening of the air inlet channel at this position gradually decreases, and the air volume gradually decreases. When the first damper 31 and the second damper 32 move to the same plane and laterally block the air inlet channel, the damper assembly 3 is in a completely closed state, the air inlet channel is completely blocked, and the air volume is zero at this time.
[0074] like Figures 4-8 As shown, the air guide assembly 2 also includes a transmission seat 22, which is synchronously rotatably connected to the air guide blade 21. The transmission seat 22 has an opening on the side away from the air guide blade 21 and a rotating cavity 221 is formed inside.
[0075] like Figures 4-7 As shown, a drive shaft 4 is provided between the air guide assembly 2 and the damper assembly 3. The end of the drive shaft 4 near the air guide assembly 2 is provided with a rotating part 41. The rotating part 41 is rotatably disposed in the rotating cavity 221, so that the air guide blade 21 can rotate relative to the air outlet housing 1 to realize the adjustment of the air outlet direction.
[0076] The end of the drive shaft 4 away from the rotating part 41 is connected to the damper assembly 3, which transmits the rotation of the guide vane 21 to the damper assembly 3, thereby controlling the opening and closing degree of the damper assembly 3.
[0077] like Figure 6 and Figure 13 As shown, a transmission part 411 is protruding from the surface of the rotating part 41 that mates with the rotating cavity 221; further reference Figure 11 A guide portion 222 is formed on the inner surface of the rotating cavity 221. The guide portion allows the transmission portion 411 to be inserted and transmits the rotation of the transmission seat 22 to the transmission shaft 4.
[0078] In the air outlet structure provided in the above embodiments of this application, a transmission shaft 4 is provided between the air guide assembly 2 and the damper assembly 3. A rotating part 41 is provided at one end of the transmission shaft 4 near the air guide assembly 2. A transmission part 411 and a guide part 222 that cooperate with each other are provided between the rotating cavity 221 and the rotating part 41, so as to reliably transmit the rotation of the air guide blade 21 to the transmission shaft 4, thereby driving the damper assembly 3 to open and close, and realizing the adjustment of the air volume.
[0079] Based on the above structural improvements, the air outlet structure proposed in this application improves the reliability and structural stability of the damper assembly 3 during the driving process while maintaining the adjustable air outlet direction, thereby ensuring the accuracy of air volume adjustment and improving the response efficiency and driving comfort of the vehicle air conditioning system.
[0080] In some embodiments, the rotating part 41 and the rotating cavity 221 form a multi-degree-of-freedom rotational engagement, so that the air guide assembly 2 can rotate relative to the air outlet housing 1 in multiple directions, thereby realizing multi-angle adjustment of the air outlet direction.
[0081] Further reference Figure 11 The guide portion 222 extends from the end of the transmission seat 22 near the guide vane 21 to the open end of the transmission seat 22. The width of the guide portion 222 is adapted to the size of the transmission portion 411 so as to transmit the rotation of the transmission seat 22 along the circumference of the guide vane 21 to the transmission shaft 4.
[0082] In the above embodiment, the rotating part 41 at one end of the transmission shaft 4 forms a multi-degree-of-freedom rotational fit with the rotating cavity 221 of the air guide assembly 2, so that the air guide blade 21 can rotate flexibly in multiple directions to achieve the adjustment of the air outlet direction; in addition, the guide part 222 has a certain extension length and the width is adapted to the size of the transmission part 411, so as to ensure the circumferential transmission effect without affecting the adjustment of the air outlet direction of the air guide blade 21.
[0083] In some embodiments, a spherical fit is formed between the rotating part 41 and the rotating cavity 221. Specifically, the rotating part 41 is designed as a sphere or a hemisphere, and the rotating cavity 221 is designed as a spherical or hemispherical inner cavity that fits with the outer surface of the rotating part 41. This spherical fit structure allows the rotating part 41 to rotate in multiple dimensions (up, down, left, right) within the rotating cavity 221, thereby giving the air guide assembly 2 greater rotational freedom, enabling it to adapt to adjustment requirements for multiple air outlet directions, and improving the flexibility and smoothness of air outlet adjustment.
[0084] When the guide vane 21 rotates relative to the air outlet housing 1 and the plane of rotation passes through the axis of the transmission shaft 4, the transmission part 411 slides along the guide part 222 without restricting the rotation of the guide vane 21, thus realizing the adjustment of the air outlet direction left and right or up and down. When the guide vane 21 rotates along its circumference, the guide part 222 transmits the rotation in this direction to the transmission part 411, which drives the transmission shaft 4 to rotate. The rotation of the transmission shaft 4 controls the opening or closing of the damper assembly 3 until the required air volume is adjusted.
[0085] In some embodiments, such as Figure 13As shown, there are two transmission parts 411, located on opposite sides of the rotating part 41; correspondingly, two guide parts 222 are provided on the inner surface of the rotating cavity 221, which respectively cooperate with the two transmission parts 411. By setting two sets of transmission parts 411 and guide parts 222, a transmission cooperation structure is formed on both sides, which can more stably transmit the rotational motion to the transmission shaft 4 when the guide vane 21 rotates in the circumferential direction, thereby improving the balance of the transmission process and the stability of the overall structure.
[0086] In some embodiments, such as Figures 8-10 As shown, the guide vane 21 includes multiple blade bodies 211 and an inner ring seat 212 located at the center of the multiple blade bodies 211. An installation cavity 213 is defined in the inner ring seat 212. The installation cavity 213 is open on the side facing the drive shaft 4. The drive seat 22 is installed in the inner ring seat 212.
[0087] The design of the inner ring seat 212 on the guide vane 21 provides an installation position for the transmission seat 22. By effectively utilizing the structure of the guide vane 21, the transmission seat 22 is housed and installed in the mounting cavity 213 of the inner ring seat 212, reducing the axial length of the air outlet structure. In addition, the transmission seat 22 being located in the inner ring seat 212 can also protect the transmission seat 22 from external impacts that could cause functional failure, thus improving the reliability of the transmission.
[0088] In some embodiments, such as Figure 10 and Figure 11 As shown, a positioning block 223 is provided on the outer wall of the transmission seat 22, and a positioning recess 2131 that cooperates with the positioning block 223 is provided on the inner surface of the mounting cavity 213. When the transmission seat 22 is installed in the inner ring seat 212, the positioning block 223 is located in the positioning recess 2131 to restrict the circumferential rotation of the transmission seat 22 relative to the inner ring seat 212, and prevent it from rotating in the inner ring seat 212 and causing transmission failure.
[0089] In some embodiments, such as Figure 10 and Figure 11 As shown, a stop portion 2132 is also provided on the inner surface of the mounting cavity 213. The stop portion 2132 is provided near the opening end of the inner ring seat 212 and protrudes from the inner surface of the inner ring seat 212. A limiting protrusion 224 is provided on the outer wall of the transmission seat 22 near the opening end of the transmission seat 22. A stop step 2241 is formed between the limiting protrusion 224 and the outer wall surface of the transmission seat 22. When the transmission seat 22 is installed in the inner ring seat 212, the stop portion 2132 is located outside the stop step 2241 and opposite to the stop step 2241, which limits the transmission seat 22 to be located in the mounting cavity 213 of the inner ring seat 212 and prevents the transmission seat 22 from coming out of the opening end of the mounting cavity 213.
[0090] In some embodiments, such as Figure 12As shown, the transmission base 22 includes a first base 225 and a second base 226 that are detachably connected. The first base 225 and the second base 226 are mated together, and their inner surfaces form a rotating cavity 221. By designing the transmission base 22 as being formed by the mating of two detachable bases, during installation, the transmission part 411 on the rotating part 41 can be easily inserted into the corresponding guide part 222 while the two bases are separated. Then, the two bases are mated together for installation. This avoids installation difficulties caused by the presence of the transmission part 411 and improves the convenience of parts assembly.
[0091] In some embodiments, such as Figure 12 As shown, the first seat 225 and the second seat 226 are fixedly installed together by a clamp 227. The clamp 227 includes two sets of clamping arms 2271 located on opposite sides. The first seat 225 and the second seat 226 are mated and located between the two sets of clamping arms 2271, and are pressed and fixed from both sides by the two sets of clamping arms 2271.
[0092] In some embodiments, such as Figures 14-17 As shown, the air vent housing 1 includes an outer shell 11 and a positioning part 12 fixed inside the outer shell 11. The positioning part 12 is a cylindrical structure extending axially along the outer shell 11. The positioning part 12 is for inserting the drive shaft 4 to position the drive shaft 4. The positioning part 12 is used to position and install the drive shaft 4 inside the air vent housing 1, while allowing the drive shaft 4 to rotate freely in the circumferential direction, thereby ensuring the normal realization of the transmission function.
[0093] In some embodiments, such as Figures 14-17 As shown, a connecting stiffener 13 connects the positioning part 12 to the air outlet housing 1. Optionally, four connecting stiffeners 13 are provided, arranged in pairs around the circumference of the positioning part 12, supporting the positioning part 12 in the middle part of the air outlet housing 1. In addition to mounting the positioning part 12, the connecting stiffeners 13 can also enhance the strength of the air outlet housing 1.
[0094] In some embodiments, such as Figure 15 and Figure 16 As shown, a portion of the sidewall at one end of the positioning part 12 protrudes axially relative to the other portion of the sidewall to form a limiting step 121 at the connection point, defining a limiting region 122 between the two limiting steps 121; a rotation limiting part 42 protrudes circumferentially on the drive shaft 4, the circumferential length of the limiting rotation part being less than the circumferential length of the limiting region 122; as Figure 14 As shown, the rotation limiting part 42 is located within the limiting area 122 to limit the rotation range of the drive shaft 4.
[0095] In the above embodiment, a limiting region 122 is formed by the structure of the positioning part 12 itself, which cooperates with the rotation limiting part 42 provided on the transmission shaft 4 to limit the rotation range of the transmission shaft 4. By limiting the rotation angle of the transmission shaft 4, the problem of not being able to perceive the rotation angle during the adjustment of the air volume is avoided. In particular, this rotation range can correspond to the opening and closing stroke of the damper assembly 3; for example, when the transmission shaft 4 rotates and the rotation limiting part 42 moves from one end of the rotation range to the other end, the damper assembly 3 changes from a fully open state to a fully closed state, or from a fully closed state to a fully open state. Through this design, the user can effectively perceive the degree of air volume adjustment, thereby being able to adjust to the required air volume and achieve precise control of the air volume.
[0096] In some embodiments, such as Figure 13 As shown, a damping part 43 surrounds the outer circumference of the drive shaft 4, and the damping part 43 is interference-fitted with the positioning part 12. The damping part 43 can both ensure the rotational stability of the drive shaft 4 and realize damped rotation.
[0097] In some embodiments, such as Figure 7 , Figure 19 and Figure 20 As shown, a transmission gear 5 is mounted on the end of the transmission shaft 4 away from the rotating part 41. The transmission gear 5 is located between the positioning part 12 and the damper assembly 3. The surface of the transmission gear 5 facing away from the transmission shaft 4 is a tooth surface, and the tooth surface is connected to the damper assembly 3 in a transmission manner.
[0098] Specifically, such as Figure 19 and Figure 20 As shown, damper gears 33 are respectively provided on the first damper 31 and the second damper 32. The damper gears 33 mesh with the transmission gears 5. The rotation of the transmission shaft 4 drives the transmission gears 5 to rotate, which in turn drives the damper gears 33 to rotate. The rotation of the damper gears 33 drives the corresponding dampers to rotate, thereby realizing the opening and closing action of the damper assembly 3. Optionally, the damper gears 33 are specifically wedge gears.
[0099] In some embodiments, such as Figure 20 and Figure 21 As shown, the surface of the transmission gear 5 facing the transmission shaft 4 is a positioning surface 51, and a positioning groove 511 is provided on the positioning surface 51; as Figure 17 and Figure 18 As shown, a mounting groove 123 is provided on the side wall of the positioning part 12, and the opening of the mounting groove 123 faces the positioning surface 51; a positioning member 61 is installed in the mounting groove 123, and an elastic member 62 is provided between the positioning member 61 and the bottom of the mounting groove. One end of the positioning member 61 extends out of the mounting groove 123 and makes pressure contact with the positioning surface 51 under the action of the elastic member 62.
[0100] The transmission shaft 4 drives the transmission gear 5 to rotate, and the positioning member 61 slides on the positioning surface 51. The positioning groove 511 is located on the sliding path of the positioning member 61. The damper assembly 3 is configured such that when the positioning member 61 slides into the positioning groove 511, the damper assembly 3 is in a fully open or fully closed state.
[0101] In the above embodiment, the positioning element 61, in conjunction with the positioning groove 511, enables the positioning of the damper's open and closed state. When the user rotates the knob ring 9, the transmission shaft 4 rotates under the cooperation of the transmission part 411 and the guide part 222, driving the transmission gear 5 to rotate. As the transmission gear 5 rotates, when the positioning element 61 slides into the positioning groove 511, under the action of the elastic element 62, the positioning element 61 will strike the bottom of the positioning groove 511, producing a crisp sound, indicating that the opening or closing is complete. When the user continues to rotate the knob ring 9, the resistance of the elastic element 62 must be overcome before the positioning element 61 can slide out of the positioning groove 511, thereby transmitting the resistance to the user and facilitating the user's perception of the rotation position. Optionally, the positioning element 61 is specifically a positioning pin, and the elastic element 62 is specifically a spring.
[0102] In some embodiments, such as Figures 22-24 As shown, the edges of the first damper 31 and the second damper 32 are covered with buffer portions 34. The buffer portions 34 are used to buffer the impacts received during the opening and closing of the first damper 31 and the second damper 32, protecting them. Simultaneously, the buffer portions 34 can also reduce impact noise during the opening and closing process, improving the noise reduction effect. The buffer portions 34 can be made of rubber.
[0103] In some embodiments, such as Figures 22-24 As shown, a first bushing 311 is provided near the rotation axis of the first damper 31, and a second bushing 321 is provided near the rotation axis of the second damper 32. The first bushing 311 and the second bushing 321 are spaced apart along the rotation axis. A first rotating shaft 312 is inserted into the first bushing 311, and a second rotating shaft 322 is inserted into the second bushing 321. An interval region is formed between the first rotating shaft 312 and the second rotating shaft 322. A first limiting post 313 is provided on the first damper 31, and a second limiting post 323 is provided on the second damper 32. The first limiting post 313 and the second limiting post 323 are located on the rotation axis and between the first rotating shaft 312 and the second rotating shaft 322 to prevent the first rotating shaft 312 or the second rotating shaft 322 from coming out of the corresponding bushing through the interval region.
[0104] In some embodiments, the air outlet 102 assembly further includes a light-emitting component 7, which includes a light-emitting element 71 and an electrical connector 72 electrically connected to the light-emitting element 71. For example...

In the above solution, the drive shaft 4 is designed as a hollow structure. The light-emitting element 71 is installed in the internal space of the drive shaft 4 and the air vent housing 1, providing ample installation space for the light-emitting element 71. Various types of light bodies can be selected as needed.
[0106] Optionally, the light-emitting element 71 in the light-emitting component 7 is specifically an ambient light tube, and the electrical connector 72 is an ambient light head; the ambient light tube extends from the ambient light head to the rotating part 41 via the drive shaft 4, and emits ambient light outward through the light-transmitting part at the front end to enhance the atmosphere in the driver's cabin.
[0107] In some embodiments, such as Figure 13 As shown, the portion of the drive shaft 4 corresponding to the receiving chamber 14 has a notch 44, through which the light-emitting body 71 enters the drive shaft 4 from the receiving chamber 14 via the notch 44, facilitating the installation of the light-emitting body 71.
[0108] In some embodiments, such as Figure 1 , Figures 25-27 As shown, a light-transmitting cover 8 is installed on the side of the inner ring seat 212 away from the drive shaft 4. The light-transmitting cover 8 is used to display optical patterns. Through the design of the light-transmitting cover 8, the light emitted by the light-emitting body 71 forms an optical pattern with decorative effect under the refraction or diffuse reflection of the light-transmitting cover 8, which enhances the atmosphere in the cabin and enhances the personalization of the interior.

[0111] In the above embodiment, the light-transmitting end cap 81 of the light-transmitting cover 8 covers the end face of the inner ring seat 212, and the light guide part 82 extends into the light-transmitting channel 26 opposite to the light-emitting body 71, effectively guiding the light emitted by the light-emitting body 71 to the light-transmitting end cap 81, thereby collecting the light and transmitting it to the user through the light-transmitting end cap 81, enhancing the uniformity and brightness of the light.
[0112] In some embodiments, such as Figure 1 and Figure 26 As shown, the air outlet structure also includes a knob ring 9, which is sleeved on the outer periphery of the inner ring seat 212. The end of the inner ring seat 212 away from the light-transmitting end cover 81 extends outward relative to the side wall of the inner ring seat 212 to form a limiting boss 214. The knob ring 9 is limited between the light-transmitting end cover 81 and the limiting boss 214 to realize the installation of the knob ring 9.
[0113] In some embodiments, such as Figure 26 As shown, a linkage part 91 protrudes from the inner surface of the knob ring 9, and a mating part 2121 is provided on the side wall of the inner ring seat 212 for the linkage part 91 to be inserted into, so that rotating the knob ring 9 drives the air guide vane 21 to rotate. The linkage part 91 and the mating part 2121 form a reliable linkage between the knob ring 9 and the inner ring seat 212. When the user rotates the knob ring 9, the linkage part 91 rotates accordingly and drives the mating part 2121, thereby driving the air guide vane 21 to rotate synchronously, realizing the adjustment of the air outlet direction or air volume. Optionally, the outer surface of the knob ring 9 is provided with anti-slip texture to increase the friction during user operation.
[0114] In some embodiments, the air guide component 2 is designed as a circular structure, which makes the air outlet facing the user aesthetically pleasing.
[0115] In some embodiments, such as Figure 8 As shown, the air guide assembly 2 also includes an air guide base 23, a fixed bracket 24, and an air guide cover 25; the air guide base 23 is located on the side of the air guide blade 21 near the air outlet housing 1; the fixed bracket 24 connects the air guide base 23 and the air guide blade 21; the air guide cover 25 is arranged around the outer periphery of the air guide blade 21.
[0116] In some embodiments, such as Figure 9 and Figure 10 As shown, the guide vane 21 also includes an outer ring 215 surrounding multiple blade bodies 211, the outer ring 215 being coaxially arranged with the inner ring seat 212; the blade body 211 extends from the outer ring 215 toward the inner ring seat 212, and two or more blade bodies 211 are connected to the inner ring seat 212.
[0117] In some embodiments, such as Figures 1-5As shown, the air outlet structure also includes a decorative strip 10 and a decorative frame 20; the decorative strip 10 is located on the user-facing side of the air outlet structure, and the decorative frame 20 extends axially along the air outlet structure and connects the decorative strip 10 and the air outlet housing 1. Optionally, the decorative strip 10, the decorative frame 20, and the air outlet housing 1 are connected by a snap-fit structure. When the air guide assembly 2 has a circular structure, the decorative strip 10 and the decorative frame 20 are designed as annular.
