[0044] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] This embodiment provides a fragrance device with a simple structure, low cost, easy assembly and disassembly, and improved work efficiency.

[0046] like Figures 1-7 As shown, the fragrance device mainly includes a fragrance diffuser housing 10, a cantilever beam 20, and a fragrance bottle 30. The fragrance diffuser housing 10 has mounting holes 101. One end of the cantilever beam 20 is connected to the fragrance diffuser housing 10, and multiple cantilever beams 20 are evenly arranged about the axis of the mounting holes 101. A snap-fit ​​portion 21 is provided on the side of the cantilever beam 20 facing the mounting holes 101. The fragrance bottle 30 has protruding ribs 32 on its periphery, which are snap-fitted to the snap-fit ​​portion 21.

[0047] Based on the above design, in the embodiment, the cantilever beam 20 and the fragrance machine shell body 10 can be integrally formed or connected by clamping. In the process of installing the fragrance bottle 30, the protruding ribs 32 on the fragrance bottle 30 can be clamped with the clamping portions 21 on the cantilever beam 20, so that the protruding ribs 32 and the clamping portions 21 form an interference fit, thereby improving the stability and reliability of the assembly of the fragrance bottle 30. When it is necessary to disassemble the fragrance bottle 30, the user only needs to exert an upward force on the fragrance bottle 30 to disengage the protruding ribs 32 on the fragrance bottle 30 from the clamping portions 21 on the cantilever beam 20, so that the fragrance bottle 30 can be pulled out, which is convenient to operate, saves time and effort, and does not need to use the existing threaded screwing method to disassemble the fragrance bottle 30, thereby improving work efficiency and saving costs. Compared with the magnetic and press-and-pop fixing methods in the prior art, the fragrance device in the embodiment has a simple structure and low cost.

[0048] It can be understood that, as shown in Figure 6 When the user needs to install the fragrance bottle 30, the user holds the fragrance bottle 30 with his hand, aligns it with the installation hole 101 of the fragrance machine shell body 10, and inserts it. When the fragrance bottle 30 is about to be inserted into the installation hole 101, a slight downward force is applied, and when a "click" sound is heard, it indicates that the fragrance bottle 30 has been installed in place, and the clamping portion 21 of the cantilever beam 20 has clamped the fragrance bottle 30. As shown in Figure 7 When the user needs to disassemble the fragrance bottle 30, one of the fragrance bottles 30 is taken and held with the hand, and a slight upward force is applied, so that the fragrance bottle 30 can be separated from the fragrance machine shell body 10, and then the fragrance bottle 30 can be pulled out.

[0049] Optionally, the cantilever beam 20 in the embodiment can be provided in three, and the three cantilever beams 20 are uniformly arranged about the axis of the installation hole 101, that is, an included angle of 120° is formed between adjacent two cantilever beams 20, so as to ensure that the fragrance bottle 30 is uniformly stressed during installation.

[0050] As shown in Figures 1-3 In the embodiment, the clamping portion 21 has a first inclined surface 211 and a second inclined surface 212 adjacent to each other, the first inclined surface 211 and the cantilever beam 20 form an entry angle a, 100°≤a≤150°; the setting of the entry angle a can form a certain guiding effect when the fragrance bottle 30 is inserted into the installation hole 101, thereby improving the installation efficiency of the fragrance bottle 30. The second inclined surface 212 and the cantilever beam 20 form a disassembly angle β, 100°≤β≤150°, the setting of the disassembly angle β can form a certain guiding effect for disassembly of the fragrance bottle 30, reduce the interference stress between the clamping portion 21 and the protruding rib 32, and facilitate disassembly of the fragrance bottle 30.

[0051] Optionally, in this embodiment, the introduction angle α can be set to values ​​such as 100°, 110°, 120°, 130°, 140°, and 150°; the disassembly angle β can be set to values ​​such as 100°, 110°, 120°, 130°, 140°, and 150°.

[0052] Furthermore, in this embodiment, a first rounded corner is formed at the adjacent junction between the first inclined surface 211 and the second inclined surface 212. The first rounded corner allows the raised rib 32 on the fragrance bottle 30 to more smoothly engage with the engaging part 21 during the engagement process, reducing jamming and resistance caused by sharp edges, thereby improving assembly efficiency. In addition, the first rounded corner reduces friction and collision between the fragrance bottle 30 and the engaging part 21 during assembly, lowering the risk of wear and damage to components. Simultaneously, the first rounded corner disperses stress, reduces stress concentration, and improves the durability of the engaging part 21.

[0053] Optionally, in this embodiment, the radius r of the first fillet is set to a range of 0.1mm ≤ r ≤ 0.5mm. When the radius r of the first fillet is too large (r > 0.5mm), the excessively large first fillet will increase the volume of the snap-fit ​​part 21, affecting the overall design. When the radius r of the first fillet is too small (r < 0.1mm), it will increase the resistance of the fragrance bottle 30 during the snap-fit ​​process, making assembly more difficult; at the same time, an excessively small first fillet will exacerbate the friction and collision between the fragrance bottle 30 and the snap-fit ​​part 21, thereby increasing the risk of wear and damage to the components.

[0054] like Figures 1-3 As shown, in this embodiment, a second rounded corner is formed at the connection between the cantilever beam 20 and the fragrance diffuser housing 10. The second rounded corner disperses the stress at the connection between the cantilever beam 20 and the fragrance diffuser housing 10, preventing cracks or fractures caused by stress concentration, enhancing structural strength, and extending service life. Simultaneously, the second rounded corner facilitates material flow during injection molding or casting, reducing defects and improving manufacturing efficiency.

[0055] Optionally, in this embodiment, the radius R of the second rounded corner is set to a range of 1.0mm ≤ R ≤ 3.0mm. When the radius R of the second rounded corner is greater than 3.0mm, the excessively large rounded corner will increase the volume of the connection, which may affect the internal layout or appearance design, resulting in a less compact overall structure of the fragrance device and adding unnecessary volume and weight. When the radius R of the second rounded corner is less than 1.0mm, the excessively small second rounded corner cannot effectively distribute stress, which may lead to cracks or breakage at the connection. At the same time, an excessively small second rounded corner will increase the processing difficulty, requiring higher precision and more complex processes to ensure processing quality, thus increasing costs.

[0056] Optionally, the thickness T of the fragrance machine shell body 10 in the embodiment can be set to 2.0 mm, and the thickness t of the cantilever beam 20 can be set to 0.5T, i.e. 1.0 mm. The protruding height Y of the clamping portion 21 (i.e. the single-side overlapping amount of the clamping portion 21) can be set to 1.0 mm ± 0.15 mm. The distance L of the clamping portion 21 from the root of the cantilever beam 20 can be set to 10.7 mm. Optionally, the protruding rib 32 in the embodiment has a third round corner, and the radius of the third round corner can be set to 1.1 mm ± 0.1 mm.

[0057] As shown in Figure 5 In the embodiment, the fragrance bottle 30 includes a bottle body 31, and the protruding rib 32 is arranged on the circumferential side of the bottle body 31. The bottle body 31 protrudes a support portion 33, the bottle body 31 passes through the mounting hole 101, and the support portion 33 is supported on the fragrance machine shell body 10. After the fragrance bottle 30 is clamped and assembled with the cantilever beam 20, the protruding rib 32 on the fragrance bottle 30 and the clamping portion 21 on the cantilever beam 20 form a clamping structure, which can avoid the risk of the fragrance bottle 30 falling out due to road bumps during vehicle operation. The arrangement of the support portion 33 can support the fragrance bottle 30 to a certain extent and avoid the fragrance bottle 30 from falling into the mounting hole 101. In other words, the clamping structure achieves the limiting effect of the fragrance bottle 30 in the vertical upward direction, and the support portion 33 achieves the limiting effect of the fragrance bottle 30 in the vertical downward direction.

[0058] As shown in Figure 5 In the embodiment, the fragrance bottle 30 further includes a bottle cap 34, the bottle cap 34 is provided with an internal thread, the bottle body 31 is provided with an external thread, and the internal thread and the external thread are threadedly connected. The bottle body 31 is used to contain essential oil or perfume, and the bottle cap 34 is threadedly connected with the bottle body 31, which facilitates the disassembly of the bottle cap 34 and is conducive to the replacement of the essential oil or perfume in the bottle body 31.

[0059] As shown in Figure 4 In the embodiment, the mounting holes 101 are arranged at equal intervals, the fragrance bottles 30 are arranged in multiple numbers, and the fragrance bottles 30 are arranged one by one corresponding to the mounting holes 101. For example, the mounting holes 101 and the fragrance bottles 30 can be arranged in three, four, five or other numbers, so that the multiple fragrance bottles 30 allow the user to switch different fragrances according to mood or occasion, improving the personalized experience. At the same time, the multiple fragrance bottles 30 mean more fragrance reserves, reducing the frequency of frequent replacement, and meeting the needs of long-time driving.

[0060] Optionally, the fragrance bottle 30 in the embodiment cooperates with the cantilever beam 20 to require selection of appropriate materials, with a focus on the frequency of disassembly of parts and the resistance to essential oil corrosion, cost advantages, and the like. First, because the fragrance bottle 30 is a consumable, it needs to be replaced every three months to half a year, and the material of the bottle body needs to be selected to be resistant to essential oil corrosion and low in cost. Polypropylene (PP) plastic has good fluidity, stable chemical properties, strong resistance to essential oil corrosion, and low cost, so polypropylene (PP) plastic is the preferred material for the fragrance bottle 30. The cantilever beam 20 that cooperates with the fragrance bottle 30 needs to be selected to be wear-resistant, tough, and resistant to essential oil corrosion, considering that it needs to be used for a long time and disassembled frequently. Nylon (PA66-GF30) material is a high-performance engineering plastic with excellent mechanical strength and toughness, high tensile strength, good wear resistance, and good resistance to essential oil corrosion, so it is suitable for high-stress mechanical parts. Therefore, nylon (PA66-GF30) material is the preferred material for the cantilever beam 20. It can be understood that the cantilever beam 20 and the clamping portion 21 in the embodiment are made of the same material, and the cantilever beam 20 and the clamping portion 21 are integrally formed.

[0061] Finite element analysis verification:

[0062] The fragrance device in the embodiment is verified by finite element analysis, which mainly simulates the plug-in force of the fragrance bottle 30 to meet the requirements under the premise of meeting the yield strength according to the characteristics of the material, repeatedly checks whether the design parameters are reasonable, and provides a theoretical basis for structural design.

[0063] The pull-out force of the fragrance bottle 30 is an important indicator for evaluating the reliability of the fragrance bottle 30. When the pull-out force of the fragrance bottle 30 is too small, there is a risk of the fragrance bottle 30 falling off; when the pull-out force of the fragrance bottle 30 is too large, it is difficult for the user to pull it out, thereby affecting the user's experience. Therefore, according to the performance requirements of the pull-out force of the fragrance bottle 30, the plug-in force index of the fragrance bottle 30 in the embodiment is 10N-30N, which is more appropriate. The following table is the FEA simulation analysis result.

[0064]

[0065] The embodiment also provides a car, which includes a vehicle body frame and the above-mentioned fragrance device, and the fragrance device is arranged on the vehicle body frame. The fragrance device is connected with the vehicle body frame through a fixing support, and is specifically arranged in an interior space of an instrument panel, a storage slot of a center console, an interior of a glove box, or a vicinity of an air outlet of an air conditioner behind a seat, so as to adapt to layout requirements of different vehicle models.

[0066] The fragrance device in the embodiment is electrically connected with the automobile circuit system, and the fragrance release concentration and mode (such as continuous release and intermittent fragrance diffusion) can be adjusted through a vehicle-mounted central control screen or a mobile terminal APP. The airflow guide channel of the fragrance device is communicated with the air duct of the air conditioner in the vehicle, the fragrance is uniformly diffused to the whole vehicle space by using the airflow of the air conditioner, and the local concentration is prevented from being too high. In addition, the surface of the shell of the fragrance device is covered with a decorative panel matched with the interior decoration of the vehicle, so that the functionality and aesthetics are unified.
