In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] The present invention provides a vehicle-mounted fragrance system, please refer to Figures 1 to 5 The vehicle fragrance system includes a box 100, a fragrance seat 800, a first driving device 510, a fragrance box 200, a fragrance cover 300, a gear 400, a second driving device 520 and an exhaust device 900. Specifically, the box 100 may include a box cover 110, a box bottom 120 and a bracket 130. Of course, the box 100 may also be integrally formed, not divided into the box cover 110, the box bottom 120 and the bracket 130. The specific adjustment can be made according to actual needs and is not limited here.

[0052] The fragrance holder 800 is rotatably connected to the housing 100. The fragrance holder 800 can rotate around a first axis 101 in the housing 100. The first axis 101 is parallel to the left and right direction. A first driving device 510 connected to the fragrance holder 800 is provided in the housing 100. The first driving device 510 is used to drive the fragrance holder 800 to rotate around the first axis 101. The fragrance box 200 is placed on the fragrance holder 800. Figure 2 As shown, a fragrance box outlet 103 is provided at the bottom of the box body 100. When the fragrance box 200 needs to be replaced, the first driving device 510 controls the fragrance holder 800 to rotate toward the fragrance box outlet 103 by a predetermined angle, such as Figure 6 As shown, the fragrance box 200 is rotated out from the bottom of the box 100, and the fragrance box 200 is exposed to the outside of the box 100 from the fragrance box outlet 103, so that the fragrance box 200 can be taken out from the fragrance box outlet 103 and replaced with a new fragrance box 200. A rotatable fragrance seat 800 is set in the box 100, and the fragrance box 200 is placed on the fragrance seat 800. When the fragrance box 200 needs to be replaced, the fragrance seat 800 can be controlled to rotate by the first driving device 510 to take out the fragrance box 200 from the fragrance box outlet 103 at the bottom of the box 100, which makes it extremely convenient to replace the fragrance box 200.

[0053] like Figure 3 As shown, there are multiple fragrance boxes 200, which are arranged in a straight line along the left and right directions. Each fragrance box 200 is provided with a fragrance cover 300 and a gear 400. The top of the fragrance box 200 is provided with a fragrance outlet. The fragrance cover 300 is covered on the fragrance outlet of the fragrance box 200 to open and close the fragrance outlet. Figure 7 The fragrance cover 300 includes a driving rod 310 and a cover plate 320 disposed at one end of the driving rod 310. The cover plate 320 is disposed on the fragrance outlet. The driving rod 310 is provided with one end of the cover plate 320 rotatably connected to the box body 100. Figure 4 , the rotation axis is the second axis 102, the second axis 102 is perpendicular to the first axis 101, and the second axis 102 is parallel to the front-rear direction. A plurality of gears 400 mesh with each other, and at least one of the gears 400 is connected to a second drive device 520 to rotate the gear 400. The gears 400 mesh with each other so that the gear 400 connected to the second drive device 520 can drive the other gears 400 to rotate, thereby reducing the number of driving parts, simplifying the structure, reducing the size of the entire vehicle fragrance system, and reducing the cost. Both the first drive device 510 and the second drive device 520 can use motors. Figure 7 and Figure 8As shown, a cam-shaped groove 410 is provided on the gear 400, and the other end of the driving rod 310 (that is, the end of the driving rod 310 without the cover plate 320) is a bent structure, and this end of the driving rod 310 is matched in the cam-shaped groove 410. When the gear 400 rotates, if the gear 400 rotates to the position where the cam-shaped top of the cam-shaped groove 410 matches the driving rod 310, the driving rod 310 can be driven to rotate, so that the corresponding fragrance cover 300 is opened, thereby opening the corresponding fragrance box 200. It is only necessary to adjust the relative position between the cam-shaped grooves 410 of each gear 400 to achieve multiple fragrance switching, and it is also possible to achieve simultaneous opening or closing of each fragrance box 200. At the same time, the opening degree of the fragrance cover 300 can be controlled, so as to achieve concentration control. Different fragrance covers 300 are driven separately by the gears 400 that mesh with each other, so that the overall structure is compact, the volume is small, and the structure is simple.

[0054] The number of the fragrance boxes 200 of the present invention can be specifically set according to needs and is not limited here. Figure 4 As shown, three fragrance boxes 200 are used, and three fragrance covers 300 and gears 400 are also used accordingly. Figures 7 to 9 As shown, among the three gears 400, the phases of the vertices a of the cam-shaped grooves 410 on the gears 400 may be consistent or inconsistent. The different relative positions of the vertices a of the cam-shaped grooves 410 on the three gears 400 can achieve different control functions, such as controlling one of the three fragrance covers 300 to open and the other two to close, or controlling the three fragrance covers 300 to open or close at the same time. According to the actual demand for changing fragrance, the positions of the vertices a of the cam-shaped grooves 410 on the three gears 400 are adjusted. Figure 8 As shown, the phases of the apexes a of the cam grooves 410 on the three gears 400 are inconsistent, as shown in FIG. Fig. 9 As shown, the phases of the apexes a of the cam grooves 410 on the three gears 400 are consistent. Figure 8 The fragrance cover 300 at the leftmost end is in an open state, and the other two fragrance covers 300 are in a closed state.

[0055] Fig.10 10 is a schematic diagram showing how the opening of each fragrance box changes with the rotation angle of the second driving device in the present invention. Figure 8 The opening of each fragrance cover 300 under the position arrangement of the gear 400 shown in the figure is schematically shown. Fig.10 The fragrance A, fragrance B and fragrance C represent the three fragrance boxes 200 corresponding to the three gears 400, and the stepper motor rotation angle represents the rotation angle of the second driving device 520. In one embodiment, the second driving device 520 can be a stepper motor, and of course it can also be other driving devices that can achieve rotational drive. Fig.10It can be seen that in the present invention, not only can any one of the fragrance covers 300 be automatically controlled to open, but also the opening degree of the fragrance cover 300 can be controlled to achieve concentration control.

[0056] like Figure 1 As shown, an exhaust device 900 is provided on the top of the box 100 . The exhaust device 900 can be, for example, a blower. The blower is connected to a duct 901 . The blower extracts the fragrance in the box 100 and transports it into the car through the duct 901 .

[0057] like Figure 3 and Figure 4 As shown, a partition 140 is provided in the box 100, and the partition 140 is arranged in the left-right direction. A storage space is formed between the partition 140 and the rear side plate of the box 100, and the fragrance box 200 is located between the partition 140 and the rear side plate of the box 100, and one end of the driving rod 310 is rotatably connected to the partition 140 and the rear side plate of the box 100. The stability of the rotation of the driving rod 310 can be improved by rotatably connecting one end of the driving rod 310 to the partition 140 and the rear side plate of the box 100 at the same time, and the driving rod 310 is rotatably connected to the partition 140 and the rear side plate of the box 100 at the same time, so that the front and rear ends of the cover plate 320 can be supported, and the stability is higher.

[0058] like Figure 3 As shown, the rotation plane of the gear 400 is perpendicular to the front-to-back direction, and the gear 400 is rotatably connected to the front side of the partition 140. After the driving rod 310 passes through the partition 140, it cooperates with the gear 400 on the front side of the partition 140. Figure 3 As described above, the three gears 400 are arranged on the same plane, and the three gears 400 are all rotatably connected to the partition 140. The gears 400 can be directly installed on the partition 140 without the need to set up an additional mounting plate for installing the gears 400, thereby reducing the number of parts, simplifying the structure, and reducing the size of the vehicle fragrance system.

[0059] like Figure 7 As shown, the driving rod 310 includes a rotating portion 311, a rocker portion 312 and a matching portion 313. The rotating portion 311 is arranged along the front-to-back direction, the rocker portion 312 is perpendicular to the rotating portion 311, and the matching portion 313 is perpendicular to the rocker portion 312 and parallel to the rotating portion 311. The rotating portion 311 is rotatably connected to the box body 100, the depth direction of the cam-shaped groove 410 is along the front-to-back direction, and the matching portion 313 is inserted into the cam-shaped groove 410 on the gear 400, so that the gear 400 can drive the driving rod 310 to rotate. When the gear 400 rotates to make the matching portion 313 located at the vertex a of the cam-shaped groove 410, the driving rod 310 can rotate under the drive of the gear 400, thereby opening the corresponding fragrance cover 300.

[0060] like Figure 4As shown, the plurality of gears 400 are sequentially arranged along the left-right direction, and the gear 400 located in the middle of the plurality of gears 400 is connected to the second driving device 520 . Figure 4 There are three gears 400, and the middle gear 400 is connected to the second driving device 520 to transmit the torque to the gears 400 on both sides of the gear 400, thereby realizing the control of all the fragrance covers 300. The middle gear 400 is connected to the second driving device 520, so that the second driving device 520 is located in the middle position of the box body 100 in the left-right direction, and the overall structure is more balanced.

[0061] like Figure 5 As shown, the partition 140 and the rear side plate of the box body 100 are arranged on the bracket 130, and the box cover 110, the bracket 130 and the box bottom 120 of the box body 100 are arranged in sequence from top to bottom, and the box cover 110, the bracket 130 and the box bottom 120 are connected by snap-fits for easy assembly.

[0062] like Figure 4 As shown, the front end of the gear 400 connected to the second driving device 520 is provided with a driving gear 420 with a diameter smaller than that of the gear 400, the driving gear 420 is connected to the second driving device 520, the driving gear 420 is arranged at the front side of the gear 400, and the output end of the second driving device 520 is provided with an output gear 521, and the output gear 521 is meshed with the driving gear 420 to transmit torque. Providing a driving gear 420 with a smaller diameter to connect with the second driving device 520 can reduce the size of the entire vehicle fragrance system, which is conducive to the optimization of the vehicle structure.

[0063] Further, such as Figure 4 As shown, the diameter of the output gear 521 is smaller than the diameter of the driving gear 420 , so that the speed can be reduced, so that the speed transmitted to the gear 400 by the second driving device 520 is reduced, which is conducive to smoothly controlling the opening and closing of each fragrance cover 300 .

[0064] In one embodiment, in combination Figure 7 and 8 As shown, when the fragrance cover 300 is in the closed state, the bottom surface 321 of the cover 320 is lower than the lowest point b of the driving rod 310. Since the fragrance box 200 is located at a position slightly lower than the driving rod 310, the bottom surface 321 of the cover 320 is designed to be lower than the lowest point b of the driving rod 310 when the fragrance cover 300 is in the closed state, so that the cover 320 can well seal the fragrance box 200 at the lower position, thereby accurately controlling the output of the fragrance.

[0065] like Figure 4 and Figure 5 As shown, the first driving device 510 is disposed on the left or right side of the housing 100. Figure 4 and Figure 5 In the embodiment, the first driving device 510 is disposed on the left side of the housing 100, but the first driving device 510 may also be disposed on the right side of the housing 100, which is not limited here. Figure 4 and Figure 5 The box 100 is provided with a first PCB board 710 for controlling the rotation angle of the first driving device 510. The first PCB board 710 is provided between the first driving device 510 and the left side wall of the box 100, and the first driving device 510 is connected to the first PCB board 710 to control the first driving device 510 through the first PCB board 710.

[0066] Please continue to refer to Figure 4 and Figure 5 A second PCB board 720 is provided at the front end of the box 100. The second PCB board 720 is used to control the rotation angle of the second driving device 520. The second PCB board 720 is arranged between the second driving device 520 and the front side wall of the box 100. The second driving device 520 is connected to the second PCB board 720 so as to control the second driving device 520 through the second PCB board 720.

[0067] like Figure 5 As shown, a plurality of fragrance box placement positions are provided on the fragrance seat 800, and a fragrance box 200 is placed on each fragrance box placement position. A sensor 810 for detecting whether a fragrance box 200 is placed on the fragrance box placement position is provided at each fragrance box placement position, and a magnet 820 for adsorbing the fragrance box 200 is provided. The sensor 810 may be a photoelectric sensor. The sensor 810 is provided to detect whether a fragrance box 200 is placed on the corresponding fragrance box placement position so that the user can understand the placement of the fragrance box 200. For example, whether a fragrance box 200 is placed on each fragrance box placement position can be displayed on the car display screen, or the user can be prompted when a fragrance box 200 is not placed on a certain fragrance box placement position, so that the user can quickly understand the situation without opening the fragrance seat 800. The magnet 820 is provided to adsorb the fragrance box 200 so that the fragrance box 200 is firmly adsorbed on the fragrance seat 800 to prevent the fragrance box 200 from moving at will, especially when the fragrance box 200 is replaced, such as Figure 6 As shown, when the fragrance box 200 is replaced, the fragrance seat 800 is in a downward tilted state, and the magnet 820 attracts the fragrance box 200 to prevent the fragrance box 200 from falling.

[0068] like Figure 5As shown, the bottom of the fragrance holder 800 is provided with a third PCB board 730 and a bottom shell 830. The third PCB board 730 is screwed to the bottom shell 830, and the bottom shell 830 can be screwed or clamped to the bottom of the fragrance holder 800. The sensor 810 is connected to the third PCB board 730, and the magnet 820 can also be set on the third PCB board 730. The third PCB board 730 is connected to the second PCB board 720 through a flexible FPC circuit board 740. Please combine Figure 2 The front bottom of the fragrance seat 800 is provided with a wire hole 801. One end of the flexible FPC circuit board 740 is connected to the second PCB board 720, and the other end is connected to the third PCB board 730 through the wire hole 801. The flexible FPC circuit board 740 is made of flexible material and can be bent and deformed. When the fragrance seat 800 rotates, the flexible FPC circuit board 740 can bend with the rotation of the fragrance seat 800 and will not interfere with the rotation of the fragrance seat 800. The second PCB board 720 is connected to the third PCB board 730 through the flexible FPC circuit board 740 to transmit the detection of the sensor 810 on the third PCB board 730 to the second PCB board 720, so that the second PCB board 720 controls the rotation of the second driving device 520 according to the detection of the sensor 810, so as to realize the switching of the fragrance type.

[0069] Please refer to Figure 2 The outer wall of the box body 100 is provided with a receiving channel 104, and the receiving channel 104 is used for the flexible FPC circuit board 740 to pass through.
