Description

Technical Field

[0001] The invention belongs to the field of vehicle-mounted fragrance, and in particular relates to a single-motor air outlet structure with a built-in fragrance system. Background Art

[0002] With the continuous development of science and technology, and the increasing attention of users to the air quality in cars, the automotive industry has an increasing demand for intelligence and environmental protection, and modern cars are equipped with more and more intelligent technologies. Among them, car fragrances, as an important branch of the automotive industry, are gradually being sought after by users because they can make drivers feel happy while driving. Car fragrances can not only refresh the air in the vehicle, cover the odor in the car, improve the overall texture and luxury, but also help drivers concentrate and reduce fatigue driving, thereby improving driving safety and pleasure.

[0003] In the current existing technology, most car fragrance generators use independent control systems to manage fragrance release, which means that users must set the wind direction / speed and fragrance concentration separately. Such separate operations are not intuitive and friendly for ordinary consumers and are easy to cause inconvenience in use. For example, when adjusting the fragrance intensity, the wind direction setting may be changed inadvertently, and vice versa. This uncoupled design limits the overall smoothness and convenience of the user experience. Summary of the invention

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] like Figures 1 to 8 As shown, a single-motor air outlet structure with a fragrance system of the present invention comprises a plurality of air guide blades 11 movably arranged in an air outlet channel 10 of a housing 1, a first transmission assembly 2 movably arranged on the housing 1, the first transmission assembly 2 movably connected to the air guide blades 11, and can drive the air guide blades 11 to swing in the air outlet channel 10; a fragrance assembly 3 and a second transmission assembly 4, the fragrance assembly 3 is arranged on the housing 1 and movably connected to the air outlet channel 10; the second transmission assembly 4 movably extends between the fragrance assembly 3 and the housing 1 to adjust the amount of fragrance flowing from the fragrance assembly 3 to the air outlet channel 10; a driving member 5 having a forward rotation state and a reverse rotation state, the first transmission assembly 2 and the second transmission assembly 4 are both connected to the driving member 5; when the driving member 5 is in the forward rotation state, the air guide blades 11 rotate while the amount of fragrance flowing from the fragrance assembly 3 to the air outlet channel 10 remains unchanged; when the driving member 5 is in the reverse rotation state, the amount of fragrance flowing from the fragrance assembly 3 to the air outlet channel 10 changes while the air guide blades 11 do not rotate.

[0023] This solution is mainly to achieve independent control of air flow and fragrance volume, specifically, Figures 1 to 8 As shown, when the driving member 5 moves along Figure 2 During the rotation in the direction of the arrow (i.e., the forward rotation state), the first transmission component 2 can drive the air guide blade 11 to swing in the air outlet channel 10, so as to realize the opening, closing, and left and right blowing functions of the air guide blade 11 on the air outlet channel 10. It is worth noting that in this state, the second transmission component 4 does not rotate with the driving member 5, and thus does not change the amount of fragrance flowing from the fragrance component 3 to the air outlet channel 10, and keeps it constant; similarly, when the driving member 5 is rotated along Figure 2During the rotation in the opposite direction of the arrow shown (i.e., the reverse state), the first transmission component 2 no longer affects the position of the air guide blade 11, i.e., the air guide blade 11 will not rotate. As the second transmission component 4 and the driving member 5 begin to rotate, the fragrance flow rate is adjusted by changing the relative position between the end of the second transmission component 4 and the fragrance component 3, thereby increasing or decreasing the amount of fragrance flowing out of the air outlet channel 10. Compared with the traditional independent fragrance generator, the present solution combines it with the air outlet channel 10, and realizes two functions (air guiding and fragrance adjustment) by using a single driving member 5, thereby simplifying the mechanical structure, saving the space occupied by the air outlet structure, improving the reliability of the system and reducing the manufacturing cost. For this reason, the user can adjust the fragrance concentration without changing the wind direction, or change the air flow direction while maintaining the same fragrance level, providing more flexible operation options.

[0024] The fragrance component 3 includes: a fragrance bin 30, an air outlet panel 12 and an extension channel 13 are provided on the shell 1, and the fragrance bin 30 is arranged in the air outlet panel 12; one end of the extension channel 13 is connected with the air outlet channel 10 and faces the wind guide blade 11, and the other end is aligned with the outlet end of the fragrance bin 30, and the two side walls of the end of the second transmission component 4 away from the first transmission component 2 are movably attached to the extension channel 13 and the outlet end of the fragrance bin 30; the fragrance support 31 is provided on the air outlet panel 12 and connected with the fragrance bin 30, and the fragrance support 31 is used to fix the fragrance block 32 to the end of the fragrance bin 30 away from the extension channel 13.

[0025] like Figures 1 to 5 As shown, the user places the fragrance block 32 in the fragrance holder 31, and the fragrance holder 31 is located on the air outlet panel 12, ensuring that the fragrance block 32 can be firmly fixed and connected with the fragrance bin 30; when the fragrance amount needs to be adjusted, the driving member 5 is reversed and the second transmission assembly 4 rotates synchronously, and when the relative position between the extension channel 13 and the outlet end of the fragrance bin 30 is changed, the amount of fragrance flowing out of the fragrance bin 30 into the extension channel 13 is controlled, and finally the fragrance passing through the extension channel 13 is blown into the in-vehicle environment through the air guide blade 11 to give the user the desired fragrance experience. In this process, since one end of the extension channel 13 faces the air guide blade 11, it helps to directly guide the fragrance into the main airflow path, achieve good mixing, improve the fragrance distribution efficiency, and make the in-vehicle or indoor environment reach the expected fragrance concentration faster.

[0026] Furthermore, it should be added that the air outlet panel 12 in the present embodiment is used to be connected to the dashboard, which also allows the fragrance tray 31 for installing the fragrance block 32 to be directly exposed to the user's field of vision, allowing the user to quickly and conveniently disassemble and replace the fragrance block 32 on the fragrance tray 31, while simplifying the user's operation process. At the same time, different air outlets in the car can be equipped with different fragrance systems (i.e., fragrance blocks 32) according to the actual needs of the user, so that each air outlet can emit a different fragrance experience, allowing the main driver and the co-driver to switch freely according to different fragrance needs.

[0027] A fragrance baffle 40 is provided at the end of the second transmission component 4 away from the driving member 5, and a flow regulating hole 400 is formed on the fragrance baffle 40. The two side walls of the fragrance baffle 40 are movably attached to the opening end of the fragrance bin 30 and the extension channel 13 respectively to adjust the opening size of the flow regulating hole 400, the opening end of the fragrance bin 30 and the extension channel 13 when they overlap.

[0028] like Figures 3 to 5 As shown, when the system is in a non-operating state or is set to non-fragrance output, the flow regulating hole 400 on the fragrance baffle 40 is not overlapped with the opening end of the fragrance bin 30 and the extension channel 13, that is, at this time, the fragrance in the fragrance bin 30 is restricted by the fragrance baffle 40 and cannot flow into the extension channel 13; as the driving member 5 moves along Figure 2 During the rotation in the opposite direction of the arrow (i.e., the reverse state), the second transmission component 4 can drive the fragrance baffle 40 to rotate relative to the shell 1, thereby pushing the fragrance baffle 40 to slide along its two side walls (close to the opening end of the fragrance bin 30 and the extension channel 13, respectively). Depending on the required amount of fragrance, the fragrance baffle 40 will be adjusted to different positions, so that the overlapping area of ​​the flow regulating hole 400, the opening end of the fragrance bin 30, and the extension channel 13 changes, thereby changing the effective cross-sectional area of ​​the fragrance flow path, and realizing precise control of the fragrance flow. It can be seen that the design of the fragrance baffle 40 combined with the flow regulating hole 400 provides a more sophisticated fragrance flow control capability, and users can fine-tune the fragrance concentration according to personal preferences or environmental requirements.

[0029] Preferably, the fragrance baffle 40 in this embodiment can be made of soft / hard rubber material according to actual needs. On this basis, both side walls of the fragrance baffle 40 can be equipped with a flange for connecting with the outlet end of the fragrance bin 30 (i.e. Figure 5 The right end of the fragrance bin 30) and the sealing ring (not shown in the figure) that is movably attached to the extension channel 13 ensure the sealing performance when the flow regulating hole 400 transports the fragrance to the extension channel 13.

[0030] Further preferably, the housing 1 in this embodiment is provided with a first limit block 14 and a second limit block 15 arranged at an angle, and the fragrance baffle 40 movably abuts against the first limit block 14 or the second limit block 15. Figure 4 As shown, at this time, the fragrance baffle 40 is against the second limit block 15, and the flow regulating hole 400 is completely misaligned with the extension channel 13 and the fragrance bin 30, so that the fragrance cannot flow into the air outlet channel 10; as the driving member 5 switches from the forward state to the reverse state, the fragrance baffle 40 can be driven by the second transmission assembly 4 to lean against the first limit block 14, which means that the preset maximum fragrance flow state is reached, and the overlapping area between the flow regulating hole 400 and the opening end of the fragrance bin 30 and the extension channel 13 reaches the maximum value, ensuring the maximum fragrance release. It is also because of the existence of the first limit block 14 and the second limit block 15 that if the fragrance release is to be reduced or the fragrance function is to be stopped, the fragrance baffle 40 will slowly approach the second limit block 15 during the rotation process to achieve the purpose of reducing or closing the fragrance flow path, ensuring that the fragrance baffle 40 can only move within the preset range, avoiding the risk of failure caused by over-adjustment, and improving the reliability and service life of the system.

[0031] Further preferably, the angle between the first limit block 14 and the second limit block 15 is 50°, that is, when the fragrance baffle 40 abuts against the first limit block 14 at the 0° position, the fragrance release amount is in the maximum open state, and when the fragrance baffle 40 abuts against the second limit block 15 at the 50° position, the fragrance release amount is zero (that is, the fragrance system on the car is turned off); the 50° angle of the limit block defines the maximum and minimum boundaries of the fragrance amount adjustment, avoids the fragrance baffle 40 from exceeding the safety range, protects the internal mechanical structure from damage, and prevents waste caused by excessive release of fragrance.

[0032] An assembly channel 300 and a guide channel 301 are provided in the fragrance chamber 30. The fragrance support 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 in and extend into the assembly channel 300. The guide channel 301 is arranged at an angle to the assembly channel 300, and one end of the guide channel 301 is connected to the assembly channel 300, and the other end is aligned with the extension channel 13 and movably connected.

[0033] like Figure 5As shown, the assembly channel 300 and the guide channel 301 in this embodiment are arranged 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 connecting port between the two. When the flow regulating holes 400, the guide channel 301 and the extension channel 13 on the fragrance baffle 40 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 this scheme makes the installation of the fragrance block 32 more intuitive and simple by designing the assembly channel 300 perpendicular to the outer wall of the air outlet panel 12, reduces the user's operation difficulty, and improves the convenience and satisfaction of use; and the design of the guide channel 301 helps to evenly distribute the fragrance before entering the main airflow, improves the mixing efficiency of the fragrance and the air, and enables the vehicle or indoor environment to reach the expected fragrance concentration faster. Preferably, the guide channel 301, the flow regulating hole 400 and the extension channel 13 in this embodiment are all arranged in a semicircular shape (not shown in the figure), which ensures that the fragrance is stably and smoothly delivered to the vehicle environment while avoiding the phenomenon of fragrance residue or loss and waste caused by the channel being too large.

[0034] The driving member 5 includes a first straight tooth 50 and a first bevel tooth 51 which are coaxially arranged. The first transmission component 2 is provided with a second straight tooth 20, and the second transmission component 4 is provided with a second bevel tooth 41. The first straight tooth 50 is movably engaged with the second straight tooth 20, and the first bevel tooth 51 is movably engaged with the second bevel tooth 41.

[0035] Specifically, Figure 2 As shown, the first bevel tooth 51 on the driving member 5 is located on one side of the first straight tooth 50. When the driving member 5 is in the forward rotation state, the driving member 5 can drive the second straight tooth 20 to rotate along Figure 2 The first transmission assembly 2 is rotated counterclockwise in the opposite direction of the arrow, and then drives the plurality of wind guide blades 11 to swing back and forth through other components of the first transmission assembly 2, so as to realize the opening and closing and left and right blowing functions of the blades in the air outlet channel 10; similarly, when the driving member 5 is in the reverse state, the driving member 5 can drive the second bevel gear 41 to rotate around its axis along the Figure 1 The fragrance baffle 40 is rotated counterclockwise, and then other parts of the second transmission assembly 4 are used to rotate to adjust the position of the fragrance baffle 40 relative to the shell 1, so that the size of the overlapping connection between the flow regulating hole 400 and the guide channel 301 and the extension channel 13 is changed, and finally the amount of fragrance delivered to the air outlet channel 10 is adjusted.

[0036] Both the first transmission assembly 2 and the second transmission assembly 4 further include: a driven wheel 60, on which the second spur gear 20 and the second bevel gear 41 are coaxially mounted; a connecting rod 61, which is located on one side of the driven wheel 60, and the driven wheel 60 is movably connected to the first connecting rod 61; a driving arm 62, a connecting plate is provided between the plurality of air guide blades 11, and the driving arm 62 is installed on the connecting plate and the fragrance baffle 40, and the driving arm 62 is movably connected to the side of the connecting rod 61 away from the driven wheel 60.

[0037] Further, if Figure 2 , Figure 3 and Figure 6 As shown, when the driving member 5 is in the forward rotation state and drives the second spur gear 20 along Figure 2 When the driven wheel 60 rotates in the opposite direction of the arrow, the driven wheel 60 will move synchronously with the second spur gear 20 because the driven wheel 60 is coaxially arranged with the second spur gear 20. In addition, because one side of the driving arm 62 is connected to a connecting plate (not shown in the figure) between a plurality of wind guide blades 11 and the other side is movably connected to the connecting rod 61, when the driven wheel 60 rotates, the connecting rod 61 can be driven to rotate along the Figure 6 The connecting rod 61 rotates counterclockwise, and the driving arm 62 is driven to rotate along the Figure 6 The air flow is synchronously rotated in the counterclockwise direction and finally transmitted to the air guide blade 11 through the connecting plate, so as to realize the opening and closing and left and right blowing functions of the air guide blade 11 in the air outlet channel 10. It should be noted that the working principle of driving the above-mentioned fragrance baffle 40 to rotate in this solution is the same as the working principle of realizing the rotation of the air guide blade 11 in the above-mentioned solution, and will not be described one by one here.

[0038] The connecting rod 61 includes: a connecting column 610 fixed on the shell 1; a rotating block 611, which is movably hinged to the connecting column 610, and a first traction block 612 and a second traction block 613 are symmetrically arranged on both sides of the rotating block 611, and a first guide groove 612a is formed in the first traction block 612, and a first traction column 600 is arranged on the driven wheel 60, and the first traction column 600 is movably engaged in the first guide groove 612a; a second guide groove 613a is formed in the second traction block 613, and a second traction column 620 is arranged on the driving arm 62, and the second traction column 620 is movably engaged in the second guide groove 613a.

[0039] Further, if Figure 3 and Figure 6As shown, the connecting rod 61 in this embodiment is composed of a connecting column 610, a rotating block 611 and two traction blocks, wherein the connecting column 610 is used to be fixed on the automobile body 1, that is, the connecting column 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, and are movably connected by the first traction column 600 on the driven wheel 60. In the first guide groove 612a, the second traction column 620 on the driving arm 62 is movably engaged in the second guide groove 613a, so that when the driven wheel 60 rotates, the first traction column 600 can be used to reciprocate in the first guide groove 612a, and the rotating block 611 is synchronously driven to rotate around the connecting column 610. When the rotating block 611 rotates, the second traction groove is bound to apply a driving force to the second traction column 620 movably engaged therein, so that the driving arm 62 rotates and finally drives the wind guide blade 11 to rotate. It can be seen that the design of the first guide groove 612a in this embodiment ensures that the first traction column 600 is not easy to be separated from the connecting rod 61 during the rotation process, and the first traction column 600 is used to apply a rotational force to the connecting rod 61, so that the second guide groove 613a can not only give the second traction column 620 a rotational force, but also play a role of limiting and guiding the second traction column 620 during the rotation process.

[0040] Limiting grooves 200 are provided in the second spur teeth 20 and the second bevel teeth 41, and the driven wheel 60 is provided with a mounting post 601 extending into the limiting groove 200, and a one-way member 602 is mounted on the mounting post 601, and the one-way member 602 is clamped in the limiting groove 200; when the driving member 5 is in the forward rotation state, the air guide blade 11 rotates and the one-way member 602 keeps the amount of fragrance flowing into the air outlet channel 10 unchanged; when the driving member 5 is in the reverse state, the amount of fragrance flowing into the air outlet channel 10 may change due to the rotation of the fragrance baffle 40, and the one-way member 602 prevents the air guide blade 11 from rotating.

[0041] like Figure 2 , Figure 7 as well as Figure 8 As shown, in this embodiment, a one-way piece 602 is installed on the mounting column 601 of the driven wheel 60, and a limiting groove 200 is provided on the second spur tooth 20 and the second bevel tooth 41. Since the second spur tooth 20 and the second bevel tooth 41 are coaxially arranged with the driven wheel 60, when the mounting column 601 and the one-way piece 602 extend into the limiting groove 200, the one-way piece 602 is clamped in the limiting groove 200. It should be noted that, as Figure 8The figure shows the installation structure of the second spur tooth 20 and the one-way member 602. Since the rotation directions of the second spur tooth 20 and the second bevel tooth 41 are different, the installation directions of the one-way member 602 and the limiting groove 200 in the second spur tooth 20 and the second bevel tooth 41 are just opposite (the specific structure of the second bevel tooth 41 and the one-way member 602 is not shown in the figure). Therefore, when the second spur tooth 20 is rotated along Figure 8 When the driving member 5 rotates clockwise, the limiting groove 200 applies a driving force to the one-way member 602, thereby causing the driven wheel 60 coaxially arranged with the second spur gear 20 to rotate synchronously. On the contrary, when the driving member 5 is in a reverse state, the first spur gear 50 on the driving member 5 drives the second spur gear 20 to rotate along the Figure 2 Rotate in the direction of the arrow shown (i.e. Figure 8 The second spur tooth 20 in the first transmission assembly 2 rotates counterclockwise), and during the rotation process at this moment, the limiting groove 200 no longer applies a driving force to the one-way member 602, so that the coaxially arranged driven wheel 60 does not rotate with the rotation of the second spur tooth 20, that is, when the driving member 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 air outlet channel 10 and the left and right wind sweeping functions of the air guide blade 11 during the movement; at this time, the driving member 5 in the forward rotation state drives it to rotate through the meshing of the first bevel tooth 51 and the second bevel tooth 41, and due to the meshing with the second bevel tooth A one-way piece 602 is also provided between the driven wheel 60 coaxially arranged with the tooth 41 and the second bevel tooth 41. The one-way piece 602 limits the rotation of the driven wheel 60 coaxial with the second bevel tooth 41, and thus cannot drive other components on the second transmission assembly 4 to rotate to achieve the fragrance baffle 40 to adjust the fragrance amount. Similarly, when the driving member 5 drives the second transmission assembly 4 to rotate the fragrance baffle 40, and the second spur tooth 20 is also rotated by the one-way piece 602, the driven wheel 60 coaxially arranged with the second spur tooth 20 will not rotate, and thus cannot drive the air guide blade 11 to rotate. The principle is the same as above and will not be repeated here.

[0042] Preferably, the one-way member 602 described in this embodiment can be replaced by other one-way structures such as a one-way damper or a ratchet, so as to ensure the separate rotation of the air guide blade 11 and the fragrance baffle 40, so as to achieve separate control switching of the air outlet and different fragrance requirements of the driver and the co-driver.

[0043] Further preferably, the output shaft of the driving member 5 in this embodiment is a spline shaft 52, and the spline shaft 52 is used to connect with a motor having a forward rotation state and a reverse rotation state. Since this solution uses one motor to drive the rotation of the air guide blade 11 and the fragrance baffle 40 respectively, the spline connection is achieved by using the output end of the motor which also has a forward rotation state and a reverse rotation state and the spline shaft 52, which is conducive to the motor transmitting a larger torque to the driving member 5, with a higher load-bearing capacity, and it is relatively stable during use, reducing vibration and noise.

[0044] It should be noted that the driving member 5 in this embodiment can be replaced by other driving devices such as a stepping motor and a servo motor.
