Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] Traditional car fragrance devices typically use solid or liquid fragrance materials, releasing the aroma through natural evaporation or wind diffusion. These devices are usually fixed to the center console or air conditioning vents, and because they are far from passengers, the diffusion effect of the fragrance is limited.

[0047] In view of this, the present application provides a seat headrest, a seat assembly, and a vehicle. By placing the fragrance device on the headrest body, the fragrance device is placed closer to the passenger's head, which helps to increase the fragrance concentration perceived by the passenger and enhance the user experience.

[0048] refer to Figures 1 to 6 In a first aspect, embodiments of this application provide a seat headrest 100 for a vehicle. The seat headrest 100 may include a headrest body 110, a headrest conduit 120, and an aromatherapy device 130.

[0049] The headrest body 110 has an installation cavity and an opening 111 communicating with the installation cavity. Part of the structure of the headrest conduit 120 is located in the installation cavity. For example, part of the structure of the headrest conduit 120 can extend along the inner contour of the installation cavity. In the area outside the installation cavity of the headrest body 110, foam plastic, memory foam or other fiber filling materials can be filled. The headrest conduit 120 can define a relatively stable installation cavity to facilitate the installation of the fragrance device 130.

[0050] The fragrance device 130 is disposed within the mounting cavity and is fixedly connected to the headrest tube 120. Exemplarily, the fragrance device 130 can be snapped together with the headrest tube 120, or it can be fixed to the headrest tube 120 by adhesive or welding. Alternatively, the fragrance device 130 and the headrest tube 120 can be fixedly connected by fasteners (such as screws, bolts, nuts, or pins). This relatively fixed connection between the fragrance device 130 and the headrest tube 120 improves the installation stability of the fragrance device 130 and reduces the impact of vibration or impact on the fragrance device 130 when the headrest body 110 vibrates or is impacted. Furthermore, when the seat headrest 100 needs to be disassembled for maintenance or replacement, only the headrest tube 120 needs to be pulled out of the vehicle seat, thus improving the replacement efficiency of the fragrance device 133.

[0051] The fragrance device 130 has a receiving cavity 131 and a vent 132 communicating with the receiving cavity 131. The receiving cavity 131 is used to contain a fragrance body 133 that can release fragrance. The fragrance body 133 can be solid or liquid. The vent 132 is exposed from the opening 111, so that when the passenger is riding, the fragrance emitted by the fragrance body 133 can be diffused to the passenger's head through the vent 132, which helps to improve the passenger's experience.

[0052] refer to Figure 1 and Figure 2 Understandably, in this application, the opening 111 can be located on the headrest body 110 at the position corresponding to the human neck, that is, on the lower side of the contact point between the passenger's head and the headrest, improving the passenger's riding experience without affecting the headrest comfort. Alternatively, the opening 111 can also be located on both sides of the headrest body 110 corresponding to the human face, so that the fragrance emanating from the ventilation hole 132 can quickly diffuse into the passenger's nasal cavity, thereby improving the passenger's riding pleasure. Of course, in other embodiments of this application, the opening 111 can also be located at other positions on the headrest, and designers can design according to their needs; this application does not impose any limitations on this.

[0053] The seat headrest 100 of this application, by placing the fragrance device 130 on the headrest body 110, brings the fragrance device 130 closer to the passenger's head, which helps to increase the fragrance concentration perceived by the passenger. Furthermore, the fragrance device 130 is fixed to the headrest tube 120, and the headrest body 110 is fixed through the headrest tube 120. Thus, even if the headrest body 110 vibrates or shakes, the fragrance device 130 will not vibrate or shake accordingly, which helps to improve the installation stability of the fragrance device 130.

[0054] Furthermore, since the fragrance device 130 is integrated into the headrest body 110, when applied to the whole vehicle, users can place different fragrances on the headrest body 110 of the corresponding seat according to their preferences, making the vehicle more personalized and thus improving user satisfaction.

[0055] refer to Figure 1 and Figure 3In some embodiments, the headrest conduit 120 includes two inserts 121 and a transition tube 122. The two inserts 121 are parallel and spaced apart, and the transition tube 122 connects the two inserts 121. The use of two parallel and spaced inserts 121 improves the installation stability of the seat headrest 100. Each insert 121 includes an inner section 121a located within the mounting cavity and an outer section 121b located outside the mounting cavity. The transition tube 122 is located within the mounting cavity and connects to both inner sections 121a. The transition tube 122 and the two inner sections 121a form a support structure for the mounting cavity, which improves the installation stability of the fragrance device 130. Simultaneously, the seat headrest 100 connects to the insertion hole on the seat via the outer section 121b, facilitating easy installation and removal and improving the efficiency of replacing and installing the fragrance body 133.

[0056] Understandably, the extension trajectory of the transition tube 122 within the mounting cavity can correspond to the ergonomic force-bearing performance of the human head, thus avoiding a decrease in the headrest comfort of the headrest body 110 due to the transition tube 122.

[0057] The fragrance device 130 is connected to at least one of the cavity section 121a and the transition tube 122. For example, the fragrance device 130 may be connected to the cavity section 121a, or the fragrance device 130 may also be connected to the transition tube 122, or the fragrance device 130 may be fixedly connected to both the cavity section 121a and the transition tube 122 at the same time, so that the fragrance device 130 is fixedly connected to the headrest guide rail, thereby improving the installation stability of the fragrance device 130.

[0058] refer to Figure 3 and Figure 4 According to some embodiments of this application, the seat headrest 100 may further include a mounting base 140, which is fixedly connected to two intracavity sections 121a, and the fragrance device 130 is disposed on the mounting base 140. By providing the mounting base 140, a stable structural foundation is provided, allowing the fragrance device 130 to be securely installed inside the headrest, preventing displacement of the fragrance device 130 due to vibration or bumps during vehicle operation. Furthermore, the design of the mounting base 140 simplifies the installation and removal process of the fragrance device 130, facilitating maintenance and replacement of the fragrance body 133.

[0059] refer to Figure 4According to some embodiments of this application, the mounting base 140 may include two seat bodies 141 corresponding to the cavity section 121a. The two seat bodies 141 are respectively connected to the corresponding cavity section 121a and are spaced apart. The seat bodies 141 may be welded to the cavity section 121a, or the seat bodies 141 may be embedded in the slots on the cavity section 121a. By setting the mounting base 140 as two separate seat bodies 141, it is beneficial to reduce the overall size of the mounting base 140, avoid occupying too much space in the headrest body 110, and thus ensure the comfort of the headrest body 110.

[0060] The fragrance device 130 may include a fixing base 134, the inner side of which defines a receiving cavity 131. The fixing base 134 is disposed between two base bodies 141. The outer wall of the fixing base 134 is provided with a connecting platform 1341 for connecting with the base bodies 141. The connecting platform 1341 is connected to the two base bodies 141 respectively. For example, the connecting platform 1341 can be fixed to the two base bodies 141 respectively by adhesive or welding, or the connecting platform 1341 can also be fixedly connected to the base bodies 141 by fasteners such as screws, bolts, nuts or pins.

[0061] By employing a connection design between two seats 141 and the cavity section 121a, the mounting base 140 provides a stable yet flexible structural foundation. The connection between the connecting platform 1341 and the seats 141 ensures relative fixation between the fixed base 134 and the mounting base 140. The large contact area between the connecting platform 1341 and the seats 141 provides greater support for the fragrance device 130, thereby improving the installation stability of the fragrance device 130 within the seat headrest 100.

[0062] In addition, the two connecting seats are connected to the two bases 141 respectively, forming a multi-point connection structure, which is conducive to further improving the installation stability of the fragrance device 130.

[0063] refer to Figure 4 According to some embodiments of this application, both bases 141 are provided with first connecting holes, and the connecting platform 1341 is provided with second connecting holes 1341a corresponding to the first connecting holes. The fixing base 134 and the mounting base 140 are fixedly connected by fasteners passing through the first connecting holes and the second connecting holes 1341a, which helps to ensure the stability and safety of the fragrance device 130 during use. This connection method facilitates installation and disassembly, and improves the convenience of maintenance and replacement.

[0064] Alternatively, the fasteners can be standard parts such as screws, bolts, nuts, and pins, which helps to save equipment costs.

[0065] The connecting platform 1341 is provided with a positioning hole 1341b, and at least one of the two bases 141 is provided with a positioning post 1411. For example, one connecting platform 1341 is provided with a positioning hole 1341b, and the corresponding base 141 is provided with a positioning post 1411. Alternatively, both connecting platforms 1341 are provided with positioning holes 1341b, and both bases 141 are provided with positioning posts 1411. The fixed base 134 and the mounting base 140 are positioned and engaged by the positioning post 1411 passing through the positioning hole 1341b, thereby improving the installation efficiency of the fragrance device 130.

[0066] By introducing the design of the first connecting hole, the second connecting hole 1341a, the positioning hole 1341b, and the positioning post 1411, the connection between the fixing seat 134 and the mounting seat 140 is made more stable and precise, forming a multi-layered connection and positioning method. This helps to ensure the stability and reliability of the fragrance device 130 during use, while simplifying the installation and maintenance process of the fragrance device 130. In turn, it helps to improve the efficiency and safety of the fragrance device 130 and is suitable for various vehicle models and usage scenarios.

[0067] Understandably, in this embodiment, since the two connecting seats are respectively connected to the two mounting seats 140, when the first connecting holes on the two connecting seats are aligned with the second connecting holes 1341a respectively, they have already played a certain positioning role for the other. Therefore, in this application, the positioning hole 1341b and the positioning post 1411 may not be provided to reduce processing costs. Alternatively, the positioning hole 1341b and the positioning post 1411 may be provided, and the installation efficiency of the fragrance device 130 may be improved through the positioning cooperation between the positioning post 1411 and the positioning hole 1341b.

[0068] refer to Figure 5 and Figure 6 According to some embodiments of this application, the fragrance device 130 may include a fixed base 134 and a movable component 135.

[0069] The inner side of the mounting base 134 defines a receiving cavity 131, which has a plug-in port 1311. The movable part 135 is detachably disposed in the receiving cavity 131 via the plug-in port 1311. The fragrance body 133 is disposed on the movable part 135, which has a vent hole 132. By introducing the design of the mounting base 134, the receiving cavity 131, the plug-in port 1311, and the movable part 135, the user can directly replace the fragrance body 133 after pulling out the movable part 135 from the plug-in port 1311. This makes the replacement and maintenance of the fragrance body 133 simple and quick, and the user can adjust the in-car fragrance environment at any time according to personal preferences.

[0070] Understandably, when the opening 111 is positioned corresponding to the passenger's neck, the direction of inserting or removing the movable member 135 from the insertion port 1311 can be the height direction of the vehicle. Alternatively, when the opening 111 is positioned corresponding to the passenger's face, the direction of inserting or removing the movable member 135 from the insertion port 1311 can be the width direction of the vehicle. In this way, while improving the convenience of replacing the fragrance body 133, the impact on the structure of the headrest body 110 is reduced, which helps to ensure the headrest comfort of the seat body.

[0071] refer to Figure 5 and Figure 6 According to some embodiments of this application, the receiving cavity 131 may include a first chamber 131a and a second chamber 131b, the first chamber 131a and the second chamber 131b being aligned with the opening 111 of the insertion / removal port 1311 (e.g., ...). Figure 6 The X-direction shown is distributed sequentially from the outside to the inside. The inner wall of the receiving cavity 131 has an inwardly protruding first latch 131c. The first chamber 131a and the second chamber 131b are respectively located on both sides of the first latch 131c. The movable member 135 is movably disposed in the first chamber 131a. For example, the movable member 135 can be inserted into the first chamber 131a along the X-direction. At this time, the fragrance device 130 is in normal use. When the fragrance body 133 is exhausted or the fragrance device 130 needs maintenance, the movable member 135 can be pulled out along the X-direction.

[0072] The fragrance device 130 may further include a snap-fit ​​member 136, a portion of which is located in the second chamber 131b, and a portion in the first chamber 131a, and is detachably connected to the movable member 135. Exemplarily, the portion of the snap-fit ​​member 136 located in the first chamber 131a and the portion of the movable member 135 facing the snap-fit ​​member 136 can be magnetically connected. When the movable member 135 is installed in the first chamber 131a, the end of the snap-fit ​​member 136 located in the first chamber 131a magnetically engages with the end of the movable member 135 facing the snap-fit ​​member 136, thereby fixing the fragrance body 133 relatively within the receiving cavity 131 and emitting fragrance. When the user needs to remove the movable member 135, a pulling force exceeding the magnetic attraction force is applied outward to remove it. Alternatively, one of the snap-fit ​​member 136 and the movable member 135 may have a protrusion facing the other, while the other may have an annular groove with a notch. When the movable member 135 is installed in the first chamber 131a, the protrusion is located in the non-notch portion of the annular groove. When it is necessary to remove the movable member 135 from the first chamber 131a, simply rotate the movable member 135 and the snap-fit ​​member 136 relative to each other, causing the protrusion to rotate to the notch, thus allowing the movable member 135 to be pulled out. This achieves a separable connection between the movable member 135 and the snap-fit ​​member 136. This separable connection between the movable member 135 and the snap-fit ​​member 136 improves the installation stability of the fragrance body 133 when the movable member 135 is installed in the receiving cavity 131. When it is necessary to replace the fragrance body 133, simply separate the movable member 135 from the snap-fit ​​member 136, and the movable member 135 can be pulled out along the insertion / removal port 1311 for replacement, making the operation convenient.

[0073] The snap-fit ​​component 136 is provided with a second snap protrusion 1361 located in the second chamber 131b. Along the opening 111 of the insertion port 1311, the first snap protrusion 131c and the second snap protrusion 1361 interfere with each other. In other words, when the snap-fit ​​component 136 slides toward the first chamber 131a, the second snap protrusion 1361 abuts against the first snap protrusion 131c. Thus, through the interference between the first snap protrusion 131c and the second snap protrusion 1361, the snap-fit ​​component 136 is prevented from coming out of the second chamber 131b. This helps to improve the installation stability of the movable component 135 in the first chamber 131a, and prevents the movable component 135 from coming out due to vehicle vibration or bumps, thereby improving the structural reliability of the fragrance device 130.

[0074] refer to Figure 5 and Figure 6According to some embodiments of this application, the fixing seat 134 may include a seat body 134a and a cover 134b. One end of the seat body 134a is open, and the cover 134b is disposed at the open end of the seat body 134a.
