Description

Technical Field

[0001] This utility model belongs to the field of in-vehicle fragrance, specifically relating to a single-motor air outlet structure with a built-in fragrance system. Background Technology

[0002] With the continuous development of technology and increasing user attention to in-car air quality, the automotive industry has a growing demand for intelligent and environmentally friendly features, leading to a proliferation of intelligent technologies in modern vehicles. Among these, in-car fragrances, as an important branch of the automotive industry, are gaining popularity due to their ability to enhance the driving experience for drivers. In-car fragrances not only freshen the air and mask odors, improving the overall quality and luxury of the vehicle, but they also help drivers concentrate, reduce fatigue, and thus improve driving safety and enjoyment.

[0003] Currently, most in-car fragrance generators use independent control systems to manage fragrance release. This means users must separately set the airflow direction / speed and fragrance concentration. Such separate operation is not intuitive or user-friendly for the average consumer and can easily cause inconvenience. For example, adjusting the fragrance intensity may unintentionally change the airflow setting; and vice versa. This decoupled design limits the overall smoothness and convenience of the user experience. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a single-motor air outlet structure with a built-in fragrance system that can achieve precise control of the oscillation of the air guide vanes and the amount of fragrance output without adding an additional driving source, so as to provide users with a personalized and comfortable user experience.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a single-motor air outlet structure with a built-in fragrance system, including a number of air guide blades movably arranged in the air outlet channel of the housing, including: a first transmission component, movably arranged on the housing, the first transmission component being movably connected to the air guide blades and capable of driving the air guide blades to swing in the air outlet channel;

[0006] A fragrance component and a second transmission component are provided. The fragrance component is disposed on the housing and is movably connected to the air outlet channel.

[0007] A drive unit having a forward rotation state and a reverse rotation state, wherein both the first transmission assembly and the second transmission assembly are connected to the drive unit;

[0008] When the drive unit is in the forward rotation state, the air guide vanes rotate while the amount of fragrance flowing into the air outlet channel remains unchanged.

[0009] When the drive unit is in the reverse state, the amount of fragrance flowing from the fragrance component into the air outlet channel changes, while the air guide vanes do not rotate.

[0010] In the above-described single-motor air outlet structure with a built-in fragrance system, the fragrance component includes:

[0011] A fragrance chamber has an air outlet panel and an extension channel on its housing, and the fragrance chamber is disposed inside the air outlet panel; one end of the extension channel is connected to the air outlet channel and faces the air guide vane, and the other end is aligned with the outlet end of the fragrance chamber; the two side walls of the end of the second transmission component away from the first transmission component are respectively movably attached to the extension channel and the outlet end of the fragrance chamber.

[0012] A fragrance holder is disposed on the air outlet panel and connected to the fragrance chamber. The fragrance holder is used to fix the fragrance block to the end of the fragrance chamber away from the extension channel.

[0013] In the above-mentioned single-motor air outlet structure with a built-in fragrance system, the fragrance chamber is provided with an assembly channel and a guide channel. The fragrance holder is located at the end of the assembly channel. The assembly channel is perpendicular to the outer wall of the air outlet panel so that the fragrance block can be fixedly snapped into and extended into the assembly channel. The guide channel is set at an angle to the assembly channel, and one end of the guide channel is connected to the assembly channel, while the other end is aligned with and movably connected to the extension channel.

[0014] In the above-mentioned single-motor air outlet structure with a built-in fragrance system, a fragrance baffle is provided at the end of the second transmission component away from the driving component. An airflow adjustment hole is formed on the fragrance baffle. The two side walls of the fragrance baffle are respectively movably attached to the opening end of the fragrance chamber and the extension channel to adjust the opening size when the airflow adjustment hole, the opening end of the fragrance chamber, and the extension channel overlap.

[0015] In the above-mentioned single-motor air outlet structure with a built-in fragrance system, the housing is provided with a first limiting block and a second limiting block arranged at an angle, and the fragrance baffle moves against the first limiting block or the second limiting block.

[0016] In the above-mentioned single-motor air outlet structure with a built-in fragrance system, the included angle between the first limiting block and the second limiting block is 50°.

[0017] In the above-mentioned single-motor air outlet structure with a built-in fragrance system, the driving component includes a first straight tooth and a first bevel tooth arranged coaxially, a second straight tooth is provided on the first transmission component, and a second bevel tooth is provided on the second transmission component. The first straight tooth and the second straight tooth are in active engagement, and the first bevel tooth and the second bevel tooth are in active engagement.

[0018] In the above-described single-motor air outlet structure with a built-in fragrance system, both the first transmission component and the second transmission component further include:

[0019] The driven gear is coaxially mounted on both the second spur tooth and the second bevel tooth;

[0020] A connecting rod is located on one side of the driven wheel, and the driven wheel is movably engaged within the first connecting rod;

[0021] A drive arm is provided with a connecting plate between several of the air guide vanes. The drive arm is installed on both the connecting plate and the fragrance baffle, and the drive arm is movably engaged with the side of the connecting rod away from the driven wheel.

[0022] In the above-mentioned single-motor air outlet structure with a built-in fragrance system, the connecting rod includes:

[0023] A connecting post fixed to the housing;

[0024] A rotating block is movably hinged to the connecting column. A first traction block and a second traction block are symmetrically arranged on both sides of the rotating block. A first guide groove is formed in the first traction block. A first traction column is provided on the driven wheel, and the first traction column is movably engaged in the first guide groove. A second guide groove is formed in the second traction block. A second traction column is provided on the drive arm, and the second traction column is movably engaged in the second guide groove.

[0025] In the above-mentioned single-motor air outlet structure with a built-in fragrance system, a limiting groove is provided in both the second straight tooth and the second bevel tooth, and a mounting post extending into the limiting groove is provided on the driven wheel. A one-way component is installed on the mounting post, and the one-way component is snapped into the limiting groove.

[0026] When the drive unit is in the forward rotation state, the air guide vane rotates and the one-way component ensures that the amount of fragrance flowing into the air outlet channel remains constant.

[0027] When the drive unit is in the reverse state, the amount of fragrance flowing into the air outlet channel can be changed as the fragrance baffle rotates, and the one-way component prevents the air guide blades from rotating.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The present invention provides a single-motor air outlet structure with a built-in fragrance system. It utilizes a single drive component to achieve dual control of the oscillation of the air guide blades and the amount of fragrance. That is, the user can adjust the fragrance concentration without changing the air direction, or change the air direction while maintaining a stable fragrance output, providing the user with a comfortable airflow environment and a pleasant fragrance experience. Moreover, the single-motor drive reduces the number of parts, lowers the manufacturing cost, simplifies the structure and saves space, and greatly improves the overall smoothness and convenience of the user experience.

[0030] (2) The air vent structure in this application allows the fragrance to be quickly and evenly distributed into the car interior environment through the fragrance chamber, which improves the efficiency and coverage of fragrance diffusion and provides users with an immediate and long-lasting fragrance. At the same time, the embedded design of the fragrance holder allows users to easily install and replace the fragrance block, ensuring that each air vent can emit a different fragrance experience, allowing the driver and passenger to switch according to different fragrance needs. It is highly flexible and provides a guarantee for the user's experience.

[0031] (3) By introducing a one-way component structure, users can flexibly select ventilation mode or fragrance intensity according to actual needs without worrying that a change in one parameter will affect the setting of another parameter, thus providing users with a more comfortable and convenient operating environment.

[0046] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0047] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0048] like Figures 1 to 8As shown, this utility model discloses a single-motor air outlet structure with a built-in fragrance system, comprising several guide vanes 11 movably disposed within the air outlet channel 10 of a housing 1; a first transmission assembly 2 movably disposed on the housing 1, movably connected to the guide vanes 11, and capable of driving the guide vanes 11 to oscillate within the air outlet channel 10; a fragrance assembly 3 and a second transmission assembly 4, the fragrance assembly 3 being disposed on the housing 1 and movably connected to the air outlet channel 10; the second transmission assembly 4 extending movably between the fragrance assembly 3 and the housing 1 to adjust the amount of fragrance flowing from the fragrance assembly 3 into the air outlet channel 10; and a drive member 5 having a forward rotation state and a reverse rotation state, with both the first transmission assembly 2 and the second transmission assembly 4 connected to the drive member 5; when the drive member 5 is in the forward rotation state, the guide vanes 11 rotate while the amount of fragrance flowing from the fragrance assembly 3 into the air outlet channel 10 remains unchanged; when the drive member 5 is in the reverse rotation state, the amount of fragrance flowing from the fragrance assembly 3 into the air outlet channel 10 changes while the guide vanes 11 do not rotate.

[0049] This solution primarily aims to achieve independent control of airflow and fragrance volume, specifically, as follows: Figures 1 to 8 As shown, when the driving element 5 moves along Figure 2 During rotation in the direction of the arrow (i.e., forward rotation), the first transmission component 2 drives the air guide vane 11 to oscillate within the air outlet channel 10, thereby opening and closing the air outlet channel 10 and blowing air left and right. It is worth noting that in this state, the second transmission component 4 does not rotate with the driving component 5, thus maintaining a constant amount of fragrance from the fragrance component 3 flowing into the air outlet channel 10. Similarly, when the driving component 5 rotates along the direction of the arrow (i.e., forward rotation), the air guide vane 11 oscillates within the air outlet channel 10. Figure 2 During the rotation in the opposite direction of the arrow (i.e., the reverse state), the first transmission component 2 no longer affects the position of the air guide vane 11, meaning the air guide vane 11 will not rotate. As the second transmission component 4 and the driving component 5 begin to rotate, the relative position between the end of the second transmission component 4 and the fragrance component 3 is changed to adjust the fragrance flow rate, thereby increasing or decreasing the amount of fragrance flowing into the air outlet channel 10. Compared to the traditional independent fragrance generator, this solution combines it within the air outlet channel 10, achieving two functions (air guiding and fragrance blending) using a single driving component 5. This simplifies the mechanical structure, saves space occupied by the air outlet structure, improves system reliability, and reduces manufacturing costs. As a result, users can adjust the fragrance concentration without changing the airflow direction, or change the airflow direction while maintaining the same fragrance level, providing more flexible operating options.

[0050] The fragrance component 3 includes: a fragrance chamber 30, on which an air outlet panel 12 and an extension channel 13 are provided, and the fragrance chamber 30 is disposed inside the air outlet panel 12; one end of the extension channel 13 is connected to the air outlet channel 10 and faces the guide vane 11, and the other end is aligned with the outlet end of the fragrance chamber 30; the two side walls of the end of the second transmission component 4 away from the first transmission component 2 are respectively movably attached to the extension channel 13 and the outlet end of the fragrance chamber 30; and a fragrance holder 31, which is disposed on the air outlet panel 12 and connected to the fragrance chamber 30, and the fragrance holder 31 is used to fix the fragrance block 32 to the end of the fragrance chamber 30 away from the extension channel 13.

[0051] like Figures 1 to 5 As shown, the user places the fragrance block 32 in the fragrance holder 31, which is located on the air outlet panel 12, ensuring that the fragrance block 32 is firmly fixed and connected to the fragrance chamber 30. When the fragrance volume needs to be adjusted, the drive component 5 reverses and the second transmission component 4 rotates synchronously. By changing the relative position between the extension channel 13 and the outlet end of the fragrance chamber 30, the amount of fragrance flowing from the fragrance chamber 30 into the extension channel 13 is controlled. Ultimately, the fragrance passing through the extension channel 13 is blown into the vehicle interior environment through the guide vane 11 to provide the user with the desired fragrance experience. During this process, since one end of the extension channel 13 faces the guide vane 11, this helps to directly guide the fragrance into the main airflow path, achieving good mixing, improving the fragrance diffusion efficiency, and allowing the vehicle interior or indoor environment to reach the expected fragrance concentration more quickly.

[0052] Furthermore, it should be added that the air vent panel 12 in this embodiment is used to connect to the dashboard, which also allows the fragrance holder 31 for installing the fragrance block 32 to be directly exposed to the user's field of vision. This enables the user to easily and quickly remove and replace the fragrance block 32 on the fragrance holder 31, simplifying the user's operation process. At the same time, it also allows different air vents in the car to be equipped with different fragrance systems (i.e., fragrance blocks 32) according to the user's actual needs, so that each air vent can emit different fragrance experiences, allowing the driver and passenger to switch freely according to different fragrance needs.

[0053] The end of the second transmission component 4 away from the drive component 5 is provided with a fragrance baffle 40. A flow adjustment hole 400 is formed on the fragrance baffle 40. The two side walls of the fragrance baffle 40 are respectively movably attached to the opening end of the fragrance chamber 30 and the extension channel 13 to adjust the opening size when the flow adjustment hole 400, the opening end of the fragrance chamber 30 and the extension channel 13 overlap.

[0054] like Figures 3 to 5As shown, when the system is in a non-working state or set to non-fragrance output, the flow adjustment hole 400 on the fragrance baffle 40 does not overlap with the opening end of the fragrance chamber 30 and the extension channel 13. That is to say, at this time, the fragrance in the fragrance chamber 30 is restricted by the fragrance baffle 40 and cannot flow into the extension channel 13; as the drive member 5 moves along Figure 2 During rotation in the opposite direction of the arrow (i.e., in reverse state), the second transmission component 4 drives the fragrance baffle 40 to rotate relative to the housing 1, thereby pushing the fragrance baffle 40 to slide along its two side walls (closely against the opening end of the fragrance chamber 30 and the extension channel 13, respectively). Depending on the desired fragrance amount, the fragrance baffle 40 will adjust to different positions, causing the overlapping area of ​​the flow adjustment hole 400, the opening end of the fragrance chamber 30, and the extension channel 13 to change, thereby altering the effective cross-sectional area of ​​the fragrance flow path and achieving precise control of the fragrance flow rate. Therefore, the design of the fragrance baffle 40 combined with the flow adjustment hole 400 provides a more refined fragrance flow control capability, allowing users to fine-tune the fragrance concentration according to personal preferences or environmental needs.

[0055] Preferably, the fragrance baffle 40 in this embodiment can be made of soft / hard rubber material according to actual needs. Furthermore, on both sides of the fragrance baffle 40, there can be fittings for connecting to the outlet end of the fragrance chamber 30 (i.e., Figure 5 The right end of the fragrance chamber 30 and the extension channel 13 are fitted with a sealing ring (not shown in the figure), thereby ensuring the airtightness when the flow port 400 delivers fragrance to the extension channel 13.

[0056] More preferably, in this embodiment, the housing 1 is provided with a first limiting block 14 and a second limiting block 15 arranged at an angle, and the fragrance baffle 40 movably abuts against the first limiting block 14 or the second limiting block 15. Figure 4 As shown, at this time, the fragrance baffle 40 abuts against the second limiting block 15, and the flow regulating hole 400 is completely misaligned with the extension channel 13 and the fragrance chamber 30, preventing the fragrance from flowing into the air outlet channel 10. As the drive component 5 switches from forward rotation to reverse rotation, the second transmission component 4 drives the fragrance baffle 40 to abut against the first limiting block 14. This means that the preset maximum fragrance flow rate has been reached, and the overlap area between the flow regulating hole 400, the opening end of the fragrance chamber 30, and the extension channel 13 reaches its maximum value, ensuring the maximum fragrance release. Because of the presence of the first limiting block 14 and the second limiting block 15, if the fragrance release is to be reduced or the fragrance function to be stopped, the fragrance baffle 40 slowly moves towards the second limiting block 15 during rotation to reduce or close the fragrance flow path. This ensures that the fragrance baffle 40 can only move within a preset range, avoiding the risk of failure due to over-adjustment and improving the reliability and service life of the system.

[0057] More preferably, the included angle between the first limiting block 14 and the second limiting block 15 is 50°. That is, when the fragrance baffle 40 abuts against the first limiting block 14 at the 0° position, the fragrance release is at its maximum open state, while when the fragrance baffle 40 abuts against the second limiting block 15 at the 50° position, the fragrance release is zero (i.e., the fragrance system in the car is turned off). The 50° included angle of the limiting blocks clearly defines the maximum and minimum boundaries of the fragrance amount adjustment, preventing the fragrance baffle 40 from exceeding the safe range, protecting the internal mechanical structure from damage, and preventing waste caused by excessive fragrance release.

[0058] The fragrance chamber 30 has an assembly channel 300 and a flow channel 301. The fragrance holder 31 is located at the end of the assembly channel 300. The assembly channel 300 is perpendicular to the outer wall of the air outlet panel 12 so that the fragrance block 32 can be fixedly snapped into and extended into the assembly channel 300. The flow channel 301 is set at an angle to the assembly channel 300, and one end of the flow channel 301 is connected to the assembly channel 300, and the other end is aligned with and movably connected to the extension channel 13.

[0059] like Figure 5 As shown, in this embodiment, the assembly channel 300 and the guide channel 301 are set at an angle, so that after the fragrance is released from the fragrance block 32, it first enters the assembly channel 300, and then enters the guide channel 301 through the connection between the two. When the flow adjustment hole 400 on the fragrance baffle 40, the guide channel 301 and the extension channel 13 overlap and are interconnected, the fragrance can flow smoothly from the guide channel 301 into the extension channel 13 and finally reach the air outlet channel 10. It can be seen that the design of the assembly channel 300, which is perpendicular to the outer wall of the air outlet panel 12, makes the installation of the fragrance block 32 more intuitive and simple, reduces the difficulty of operation for users, and improves the convenience and satisfaction of use. The design of the guide channel 301 helps the fragrance to be evenly distributed before entering the main airflow, improves the mixing efficiency of fragrance and air, and allows the car or indoor environment to reach the expected fragrance concentration more quickly. Preferably, in this embodiment, the flow channel 301, the flow adjustment hole 400, and the extension channel 13 are all arranged in a semi-circular shape (not shown in the figure). This ensures that the fragrance is stably and smoothly delivered to the vehicle interior environment, while also avoiding the phenomenon of fragrance residue or loss due to excessively large channels.

[0060] The driving component 5 includes a first straight tooth 50 and a first bevel tooth 51 arranged coaxially. A second straight tooth 20 is provided on the first transmission component 2, and a second bevel tooth 41 is provided on the second transmission component 4. The first straight tooth 50 and the second straight tooth 20 are in active engagement, and the first bevel tooth 51 and the second bevel tooth 41 are in active engagement.

[0061] Specifically, such as Figure 2As shown, the first bevel tooth 51 on the drive member 5 is located on one side of the first spur tooth 50. When the drive member 5 is in the forward rotation state, the drive member 5 can drive the second spur tooth 20 along... Figure 2 The arrow indicates a counter-clockwise rotation, which in turn drives several guide vanes 11 to reciprocate through other components of the first transmission assembly 2, thereby enabling the vanes to open and close and blow air left and right within the air outlet duct 10. Similarly, when the drive component 5 is in the reverse state, it can drive the second bevel tooth 41 to rotate around its axis. Figure 1 The fragrance baffle 40 is rotated counterclockwise, and other components of the second transmission assembly 4 are used to rotate the fragrance baffle 40 to adjust the position of the fragrance baffle 40 relative to the housing 1. This changes the size of the overlap between the flow adjustment hole 400 and the flow guide channel 301 and the extension channel 13, and ultimately adjusts the amount of fragrance delivered to the air outlet channel 10.

[0062] Both the first transmission assembly 2 and the second transmission assembly 4 further include: a driven wheel 60, on which the driven wheel 60 is coaxially mounted; a connecting rod 61 located on one side of the driven wheel 60, with the driven wheel 60 movably engaged within the first connecting rod 61; and a drive arm 62, on which a connecting plate is provided between several air guide vanes 11, with the drive arm 62 mounted on both the connecting plate and the fragrance baffle 40, and the drive arm 62 movably engaged on the side of the connecting rod 61 away from the driven wheel 60.

[0063] Furthermore, such as Figure 2 , Figure 3 and Figure 6 As shown, when the driving component 5 is in the forward rotation state and drives the second spur tooth 20 along... Figure 2 When rotating in the opposite direction of the arrow, since the driven wheel 60 is coaxial with the second spur gear 20, the driven wheel 60 will move synchronously with the second spur gear 20. Furthermore, because one side of the drive arm 62 is connected to a connecting plate (not shown in the figure) between several guide vanes 11, and the other side is movably engaged with the connecting rod 61, when the driven wheel 60 rotates, it can drive the connecting rod 61 along... Figure 6 Rotating counterclockwise, while connecting rod 61 rotates, it also drives drive arm 62 along... Figure 6 The airflow rotates synchronously counterclockwise, and the signal is transmitted to the air guide vane 11 via the connecting plate, thus enabling the air guide vane 11 to open and close within the air outlet channel 10 and to blow air left and right. It should be noted that the working principle for driving the fragrance baffle 40 to rotate in this solution is the same as the working principle for driving the air guide vane 11 to rotate, and will not be repeated here.

[0064] The connecting rod 61 includes: a connecting column 610 fixed on the housing 1; a rotating block 611 movably hinged to the connecting column 610; a first traction block 612 and a second traction block 613 symmetrically arranged on both sides of the rotating block 611; a first guide groove 612a formed in the first traction block 612; a first traction column 600 provided on the driven wheel 60; the first traction column 600 movably engaged in the first guide groove 612a; a second guide groove 613a formed in the second traction block 613; a second traction column 620 provided on the drive arm 62; the second traction column 620 movably engaged in the second guide groove 613a.

[0065] Furthermore, such as Figure 3 and Figure 6 As shown, in this embodiment, the connecting rod 61 consists of a connecting post 610, a rotating block 611, and two traction blocks. The connecting post 610 is used to fix it to the car body 1, that is, the connecting post 610 is the rotation center of the rotating block 611. In addition, in this embodiment, a first guide groove 612a and a second guide groove 613a are respectively provided on the first traction block 612 and the second traction block 613. The first guide groove 612a and the second guide groove 613a are collinear and not connected to each other. They are movably engaged by the first traction post 600 on the driven wheel 60. Within the first guide groove 612a, the second traction column 620 on the drive arm 62 is movably engaged within the second guide groove 613a. This allows the driven wheel 60 to reciprocate within the first guide groove 612a when it rotates, simultaneously driving the rotating block 611 to rotate around the connecting column 610. Simultaneously, the rotation of the rotating block 611 inevitably applies a driving force to the second traction column 620, which is movably engaged within it, causing the drive arm 62 to rotate and ultimately driving the guide vane 11 to rotate. Therefore, this embodiment, through the design of the first guide groove 612a, ensures that the first traction column 600 is not easily dislodged from the connecting rod 61 during rotation. Simultaneously, by utilizing the rotational force applied to the connecting rod 61 by the first traction column 600, the second guide groove 613a, while providing rotational force to the second traction column 620, also serves to limit and guide the second traction column 620 during rotation.

[0066] Both the second straight tooth 20 and the second bevel tooth 41 are provided with limiting grooves 200. The driven wheel 60 is provided with a mounting post 601 extending into the limiting groove 200. A one-way component 602 is installed on the mounting post 601 and is engaged in the limiting groove 200. When the driving component 5 is in the forward rotation state, the air guide vane 11 rotates and the one-way component 602 keeps the amount of fragrance flowing into the air outlet channel 10 constant. When the driving component 5 is in the reverse rotation state, the amount of fragrance flowing into the air outlet channel 10 can be changed by the rotation of the fragrance baffle 40, and the one-way component 602 prevents the air guide vane 11 from rotating.

[0067] like Figure 2 , Figure 7 as well as Figure 8 As shown, in this embodiment, a one-way component 602 is installed on the mounting post 601 of the driven wheel 60. Limiting grooves 200 are provided on both the second straight tooth 20 and the second bevel tooth 41. Since the second straight tooth 20 and the second bevel tooth 41 are coaxially arranged with the driven wheel 60, when the mounting post 601 and the one-way component 602 extend into the limiting groove 200, the one-way component 602 is engaged within the limiting groove 200. It should be noted that, as... Figure 8 The diagram shows the mounting structure of the second straight tooth 20 and the one-way component 602. Since the rotation directions of the second straight tooth 20 and the second bevel tooth 41 are different, the installation directions of the one-way component 602 and the limiting groove 200 within the second straight tooth 20 and the second bevel tooth 41 are also exactly opposite (the specific structural diagram of the second bevel tooth 41 and the one-way component 602 is not shown). Therefore, when the second straight tooth 20 rotates along… Figure 8 When rotating clockwise, the limiting groove 200 applies a driving force to the one-way member 602, thereby causing the driven wheel 60, which is coaxially arranged with the second spur tooth 20, to rotate synchronously. Conversely, when the driving member 5 is in the reverse direction, the first spur tooth 50 on the driving member 5 drives the second spur tooth 20 to rotate clockwise. Figure 2 Rotate in the direction of the arrow shown (i.e.) Figure 8 The second spur tooth 20 rotates counterclockwise. During this rotation, the limiting groove 200 no longer applies driving force to the one-way component 602, so the coaxial driven wheel 60 does not rotate with the rotation of the second spur tooth 20. That is, when the driving component 5 is in the forward rotation state, the rotation of the first spur tooth 50 drives the second spur tooth 20 to rotate, thereby driving other components on the first transmission assembly 2 to realize the opening and closing of the guide vane 11 on the air outlet channel 10 and the left and right sweeping function during the movement. At this time, the driving component 5 in the forward rotation state is driven to rotate by the meshing of the first bevel tooth 51 and the second bevel tooth 41. A one-way component 602 is also provided between the driven wheel 60 and the second bevel tooth 41, which are coaxially arranged. The one-way component 602 restricts the rotation of the driven wheel 60, which is coaxial with the second bevel tooth 41, so that it cannot drive the other parts on the second transmission assembly 4 to rotate and thus achieve the adjustment of the fragrance amount by the fragrance baffle 40. Similarly, when the driving component 5 drives the second transmission assembly 4 to rotate the fragrance baffle 40, the one-way component 602 also causes the second straight tooth 20 to rotate. In this case, the driven wheel 60, which is coaxial with the second straight tooth 20, will not rotate, so it cannot drive the air guide vane 11 to rotate. The principle is the same as above, and will not be repeated here.

[0068] Preferably, the one-way component 602 described in this embodiment can be replaced by other one-way structures such as a one-way damper or ratchet, so as to ensure that the air guide vane 11 and the fragrance baffle 40 rotate separately, and realize the individual control switching of air outlet and different fragrance needs of the driver and passenger.

[0069] More preferably, in this embodiment, the output shaft of the drive component 5 is a splined shaft 52, which is used to connect to a motor having forward and reverse rotation states. Since this solution uses one motor to drive the rotation of the air guide vane 11 and the fragrance baffle 40 respectively, and uses the output end of the motor, which also has forward and reverse rotation states, to achieve a splined connection with the splined shaft 52, it is beneficial to enable the motor to transmit a larger torque to the drive component 5, resulting in higher load-bearing capacity and smoother operation, while reducing vibration and noise.

[0070] It should be noted that the driving component 5 in this embodiment can be replaced by other driving devices such as stepper motors and servo motors.
