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

[0035] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] The present invention provides a vehicle-mounted fragrance switching structure, please refer to Figures 1 to 4 The vehicle-mounted fragrance switching structure includes a box body 100, a fragrance box 200, a fragrance cover 300 and a gear 400. Specifically, the box body 100 may include a box cover 110, a box bottom 120 and a bracket 130. Of course, the box body 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.

[0037] There are multiple fragrance boxes 200, fragrance covers 300 and gears 400, and the number corresponds to each other, that is, one fragrance box 200 corresponds to one fragrance cover 300 and one gear 400. The fragrance box 200 is arranged in the box body 100, and a fragrance outlet is arranged on the fragrance box 200. The fragrance cover 300 is used to open and close the fragrance outlet. Figure 5 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 covers the fragrance outlet. The driving rod 310 is provided with one end of the cover plate 320 and is rotatably connected to the box body 100. A plurality of gears 400 are meshed with each other, and at least one of the gears 400 is connected to a driving device 500 to rotate the gear 400. Figure 5 and Figure 6As shown, a cam 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 fitted in the cam 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 cooperates with 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 positions of the cam-shaped grooves 410 of each gear 400 to achieve switching of multiple fragrances, and it is also possible to open or close each fragrance box 200 at the same time. At the same time, the opening degree of the fragrance cover 300 can be controlled to achieve concentration control, and different fragrance covers 300 are driven respectively by the gears 400 that mesh with each other, so that the overall structure is compact and the volume is small. Only one driving device 500 is required to drive one of the gears 400 to drive the other gears 400 through the gear 400. There are fewer driving devices 500, which further reduces the volume and reduces the cost. The vehicle-mounted fragrance switching structure of the present invention is streamlined and easy to assemble.

[0038] 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 5 to 7 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 realize 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 6 As shown, the phases of the apexes a of the cam grooves 410 on the three gears 400 are inconsistent, as shown in FIG. Figure 7 As shown, the phases of the apexes a of the cam grooves 410 on the three gears 400 are consistent. Figure 6 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.

[0039] Figure 8 8 is a schematic diagram showing how the opening of each fragrance box changes with the rotation angle of the driving device in the present invention. Figure 6 The opening of each fragrance cover 300 under the position arrangement of the gear 400 shown in the figure is schematically shown. Figure 8The fragrance A, fragrance B and fragrance C represent three fragrance boxes 200 corresponding to the three gears 400, and the stepper motor rotation angle represents the driving device 500. In one embodiment, the driving device 500 can be a stepper motor, and of course it can also be other driving devices that can achieve rotational drive. Figure 8 It 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.

[0040] like Figure 2 and Figure 3 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 arranged 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.

[0041] like Figure 2 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 2 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 volume of the vehicle-mounted fragrance switching structure.

[0042] like Figure 5 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.

[0043] like Figure 2As 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 driving device 500 . Figure 2 There are three gears 400 shown, and the middle gear 400 is connected to the driving device 500 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. Connecting the middle gear 400 to the driving device 500 not only makes the driving device 500 located in the middle position of the box body 100 along the left-right direction, making the overall structure more balanced, but also facilitates the arrangement of the connector 600 and the control board 700. The connector 600 is used to connect to an external power source, and the control board 700 is used to control the rotation angle of the driving device 500.

[0044] Specifically, Figure 2 and Figure 4 As shown, the driving device 500 adopts a stepper motor, and a mounting seat 101 for mounting the stepper motor is provided in the box 100. Further, as shown in FIG. Figure 4 As shown, the mounting base 101 is arranged on the box bottom 120, the partition 140 and the rear side plate of the box body 100 are arranged on the bracket 130, 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.

[0045] like Figure 2 As shown, a driving gear 420 having a smaller diameter than the gear 400 is disposed on the gear 400 connected to the driving device 500. The driving gear 420 is connected to the driving device 500 and disposed at the front side of the gear 400. An output gear 510 is disposed at the output end of the driving device 500. The output gear 510 meshes with the driving gear 420 to transmit torque. Providing a driving gear 420 with a smaller diameter to connect to the driving device 500 can reduce the size of the entire vehicle-mounted fragrance switching structure. For example Figure 2 As shown, the output gear 510 is meshed with the lower end of the driving gear 420. Compared with directly meshing the output gear 510 with the gear 400, the size of the vehicle fragrance switching structure in the up and down directions can be reduced, and the volume of the vehicle fragrance switching structure can be reduced, which is beneficial to the optimization of the vehicle structure.

[0046] Further, such as Figure 2 As shown, the diameter of the output gear 510 is smaller than the diameter of the driving gear 420 , so that the speed can be reduced, so that the speed transmitted from the driving device 500 to the gear 400 is reduced, which is conducive to smoothly controlling the opening and closing of each fragrance cover 300 .

[0047] In one embodiment, in combination Figure 5 and Figure 6As 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.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
