[0044] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0045] Reference below Figure 1-Figure 8 The light-emitting knob structure according to the embodiment of the present application is described.

[0046] Reference Figures 1 to 3 The light-emitting knob structure 100 includes a housing 110 , a light-guiding portion 120 and a light-emitting component 130 .

[0047] The housing 110 is provided with a light-transmitting area.

[0048] Since the technology of the housing 110 of the knob structure is mature, the specific structure of the housing 110 of the knob structure is not described in detail in this application. And the specific structure of the housing 110 of the knob structure is not limited in this application. In addition, it should be noted that the material of the housing 110 is PC material. In addition, after the housing 110 is injection molded, a light-transmitting area can be formed on the housing 110 in sequence by physical vapor deposition process-radium carving-UV paint spraying. In this way, through continuous production steps such as physical vapor deposition process, laser carving and UV paint spraying, the production cycle can be greatly shortened and the production efficiency can be improved. By forming a light-transmitting area on the housing 110, the appearance of the product can be made more beautiful and attractive. At the same time, the light-transmitting area can also improve the recognition of the product, which is conducive to the shaping of the brand image. The formation of a light-transmitting area can not only play a decorative role, but also increase the functionality of the product. For example, the light-transmitting area can be used as an indicator or sign to display status or direction, etc. Through high-quality production processes such as physical vapor deposition process, laser carving and UV paint spraying, a more uniform and smooth light-transmitting area can be obtained, thereby improving product quality. Through continuous production steps, waste and loss in the production process can be reduced, thereby reducing production costs. By forming a light-transmitting area on the housing 110, the product can be made unique and differentiated, thereby increasing the competitiveness of the product in the market.

[0049] PVD process is the physical vapor deposition process, which is called Physical Vapor Deposition in English. It is a technology that uses physical methods to vaporize the surface of the material source into gaseous atoms, molecules or partially ionize them into ions under vacuum conditions, and deposits a thin film with some special functions on the surface of the substrate through a low-pressure gas (or plasma) process.

[0050] UV paint is a kind of ultraviolet light-curing paint, also known as light-curing coating. It is applied to the furniture board surface through the automatic roller coating of the machine equipment. Under ultraviolet light, the initiator decomposes, causing the resin reaction, and instantly solidifies into a film. It is a relatively environmentally friendly paint. UV paint plays a role in protecting the primer and decoration with its good environmental protection, chemical resistance, physical damage resistance, high hardness and fast drying characteristics. Generally, the paint surface of the primer and the middle coat is too soft and easy to scratch. The UV paint surface is harder and scratch-resistant. UV paint can also be set to different gloss levels to enhance the texture and added value of the coated object. However, in the process of spraying UV on plastics and metal surfaces such as nylon and PP, the coating adhesion is often poor and the paint falls off due to the substrate. An effective solution is to use Jiongsheng adhesion promoter to enhance the interlayer adhesion between the substrate and the coating to solve the paint falling problem. The Baige adhesion test reaches 5B.

[0051] There are many ways to provide the housing 110 with a light-transmitting area. For example, in one embodiment, the housing 110 is at least partially transparent, so that the transparent portion can form a light-transmitting area. In other embodiments, a window may be further provided on the housing 110, and the window may be covered with a transparent cover, etc. Specifically, this application does not limit this. In addition, there are many locations for the light-transmitting area. In one embodiment, the light-transmitting area may be provided on the side of the housing 110. In one embodiment, the light-transmitting area may be provided on the top of the housing 110. In other embodiments, the light-transmitting area may be provided on both the side and the top of the housing 110. Specifically, the specific setting of the light-transmitting area may be selected as needed, and this application does not limit this.

[0052] Reference Figure 2 and Figure 4 , the light guide 120 is installed in the housing 110 and is connected to the housing 110 in a non-rotatable manner. In this way, this design allows the light guide 120 to be installed in the housing 110, and can greatly simplify the installation process and improve the installation efficiency. Since the light guide 120 is connected to the housing 110 in a non-rotatable manner, the installation position of the light guide 120 in the housing 110 is more stable, which can effectively prevent the light guide 120 from shifting or falling off during installation or use. This structure can avoid the safety risks caused by the light guide 120 accidentally falling off during installation or use.

[0053] In addition, the provision of the light guide portion 120 can form a uniform and soft lighting effect on the surface of the light-emitting knob structure 100 to enhance the user experience. The light guide portion 120 is usually made of optical materials such as optical fibers or optical plastics. Its function is to guide the light emitted by the light-emitting component 130 inside the shell 110 to the surface of the shell 110 and form a bright lighting effect on the surface of the knob. By providing the light guide portion 120, it can be ensured that the lighting effect on the surface of the light-emitting knob structure 100 remains stable during rotation, while avoiding glare and dazzling. In addition, the design of the light guide portion 120 can also be customized according to actual needs to achieve different lighting effects and colors to meet the needs and preferences of different users.

[0054] It should be noted that the light guide portion 120 may be made of a variety of materials. For example, the light guide portion 120 may be made of at least one of polycarbonate, polymethyl methacrylate, polyethyl methacrylate, polystyrene and polylactic acid. These materials have different characteristics and applicable scenarios. The choice of material depends on the specific application needs and product requirements. The present application does not limit the specific material selection of the light guide portion 120.

[0055] The light-emitting component 130 is installed in the housing 110. The light-emitting component 130 includes a circuit board 131 and a light-emitting part 132 installed on the circuit board 131. In this way, electrical energy can be directly converted into light energy with high efficiency and low energy consumption. The circuit board 131 is connected to the housing 110, which can provide stable support and connection, so that the light-emitting component 130 is more stable and reliable during installation and use. At the same time, the circuit board 131 can also realize the power supply and control of the light-emitting component 130. The circuit board 131 is used to support the light guide part 120. In this way, the support limit of the light guide part 120 is realized to prevent the circuit board 131 from shaking. The light emitted by the light-emitting part 132 is suitable for irradiating the light-transmitting area through the light guide part 120. In this way, the light emitted by the light-emitting part 132 is guided and diffused by the light guide part 120, and a uniform and soft lighting effect can be formed in the light-transmitting area.

[0056] It should be noted that in the embodiment of the present application, the circuit board 131 includes a PCB, which is the abbreviation of Printed Circuit Board. The Chinese name is a printed circuit board 131, also known as a printed circuit board, which is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. It transfers the circuit to the substrate by image transfer, and generates the circuit after chemical etching. Since the PCB is made by electronic printing, it is called a printed circuit board 131. In addition, in other embodiments, the selection of the circuit board 131 can be selected as needed, and the present application does not limit this.

[0057] According to the luminous knob structure 100 of the present application, since the luminous part 132 is installed on the circuit board 131, and the circuit board 131 is connected to the housing 110, the position of the luminous part 132 is limited. Under the support of the circuit board 131, the light guide part 120 is easy to install and operate, and the self-luminescence of the knob structure can be achieved, thereby improving the visibility, practicality and uniqueness of the luminous knob structure 100, simplifying the operation and saving energy. In addition, the light guide part 120 is connected to the housing 110 so that the light emitted by the luminous part 132 is guided and diffused by the light guide part 120, and a uniform and soft lighting effect can be formed in the light-transmitting area. In addition, the lighting effect of the luminous part 132 can be kept stable during rotation, while avoiding glare and blinding. Since the light guide portion 120 is directly in contact with the circuit board 131, the structural layout of the light guide portion 120 and the light-emitting component 130 is compact, which can reduce the volume of the light-emitting knob structure 100 to a certain extent, and can reduce the number of parts of the light-emitting knob structure 100, thereby reducing the manufacturing cost of the light-emitting knob structure 100 and simplifying the production process requirements.

[0058] It should be noted that the self-luminous characteristic makes the illuminated knob clearly visible in any environment and at any time, enhancing its visibility. This is very important for devices that need to be quickly identified and operated. The self-luminous knob can be used in dark or low-light environments, which improves its practicality. Whether at night or in other low-light environments, users can clearly see the status and position of the knob. The self-luminous knob can bring a unique appearance design to the product, making it stand out from many competing products. This design can also serve as a brand logo to enhance the recognition of the product. The use of self-luminous knobs can simplify the operation steps. In some cases, users do not need to rely on external light sources or manually turn on lighting equipment, thereby improving the convenience and efficiency of operation. Compared with knobs that require external light sources, self-luminous knobs can save energy. It does not require additional lighting equipment or batteries to provide light, thereby extending the service life of the product and reducing operating costs. The self-luminous knob can be used at night or in low-light environments, reducing the possibility of misoperation due to unclear vision and improving the safety of the product. The design of the self-luminous knob can increase the value of the product. It not only improves the practicality and visibility of the product, but also can be used as a selling point for differentiated competition to attract consumers and increase the price of the product.

[0059] Reference Figure 2 and Figure 3In one embodiment, the light guide 120 and the circuit board 131 are elastically abutted, so that external vibrations and shocks can be effectively buffered and absorbed, and the stability and reliability of the light emitting component 130 during use can be ensured. Since the light guide 120 and the circuit board 131 are elastically connected, it can avoid damage or short circuit to the light emitting component 130 in unexpected situations, such as falling, impact, etc., thereby improving the safety of the product. The design of the elastic connection can make the installation and maintenance between the light guide 120 and the circuit board 131 more convenient. During installation, the stability and tightness of the connection can be achieved by adjusting the position and tightening degree of the elastic material. During maintenance, the light guide 120 or the circuit board 131 can be easily disassembled and replaced without affecting the normal use of other components. This elastic connection design can be applied to light guides 120 and circuit boards 131 of different types and specifications, and has a wide range of applications. At the same time, since the connection between the light guide 120 and the circuit board 131 is detachable, it can be flexibly combined and customized according to actual needs.

[0060] Reference Figures 1 to 4 There are many ways to achieve elastic contact between the light guide 120 and the circuit board 131. In one embodiment, a plurality of elastic ribs 141 are provided on the first end surface of the light guide 120 facing the circuit board 131. The plurality of elastic ribs 141 are arranged at intervals along the circumference of the housing 110. The plurality of elastic ribs 141 are used to contact the circuit board 131. In this way, the provision of the plurality of elastic ribs 141 can increase the contact area between the light guide 120 and the circuit board 131, thereby enhancing the stability of the light emitting component 130 during use. At the same time, the elastic ribs 141 arranged at intervals along the circumference of the housing 110 can also effectively prevent relative displacement between the light guide 120 and the circuit board 131. The design of the plurality of elastic ribs 141 can make the connection between the light guide 120 and the circuit board 131 more convenient. Since the plurality of elastic ribs 141 can disperse the force, the fatigue degree of the light guide 120 and the circuit board 131 during use is reduced. At the same time, since the elastic rib 141 has good buffering performance, it can also absorb external impact and vibration, thereby extending the service life of the light emitting component 130.

[0061] It should be noted that the elastic rib 141 can be made of a variety of materials. For example, the elastic rib 141 can be made of elastic rubber, silicone or plastic. Specifically, the present application does not limit the specific material of the elastic rib 141.

[0062] Reference Figure 3 and Figure 8, in one embodiment, the height of the elastic rib 141 is H, where 0.1 mm ≤ H ≤ 0.3 mm. In this way, the elastic rib 141 with a height between 0.1 mm and 0.3 mm can provide appropriate elasticity and buffering performance, be able to adapt to external impacts and vibrations, and at the same time can effectively support and fix the light guide part 120 and the circuit board 131. When the height of the elastic rib 141 is within this range, the connection between the light guide part 120 and the circuit board 131 can be ensured to be stable and reliable. Due to the elastic effect of the rib, even in the case of external vibration or impact, the connection between the light guide part 120 and the circuit board 131 will not be damaged. An elastic rib 141 with too low a height may not provide enough supporting force, resulting in an unstable connection between the light guide part 120 and the circuit board 131. While an elastic rib 141 with too high a height may generate too large a pressing force between the light guide part 120 and the circuit board 131, causing damage to the light guide part 120 or the circuit board 131. Therefore, the height of the elastic rib 141 within this range can prevent the problem of over-crimping. The height of the elastic rib 141 between 0.1 mm and 0.3 mm is a relatively ideal range for manufacturing and processing. Within this range, the manufacturing and processing difficulty of the rib is moderate, which can ensure production efficiency and product quality.

[0063] Preferably, the height of the elastic rib 141 is 0.2 mm. Of course, in other embodiments, the height of the elastic rib 141 can be selected as needed, and the present application does not limit this.

[0064] , in one embodiment, the compression amount of the elastic rib 141 is K, where 0 < K ≤ 0.05 mm. In this way, when the compression amount of the elastic rib 141 is between 0 and 0.05 mm, it can ensure that the elastic rib 141 has a certain compression space when subjected to pressure, and at the same time will not be over-compressed and lose its elasticity. An appropriate compression amount can provide better buffering and supporting effects. Since the compression amount of the elastic rib 141 is within this range, the connection between the light guide part 120 and the circuit board 131 can be ensured to be stable and reliable. Even in the case of external vibration or impact, the elastic rib 141 can absorb and disperse the impact force to a certain extent, avoiding damage to the connecting components. If the compression amount of the elastic rib 141 is too large, its original elasticity and buffering performance may be damaged, resulting in an unstable connection between the light guide part 120 and the circuit board 131. While if the compression amount is too small, its supporting and fixing functions may not be fully exerted. Therefore, the compression amount within this range can prevent the problem of over-compression. When the elastic rib 141 is used within an appropriate compression range, the durability of its elasticity and buffering performance can be ensured, thereby extending the service life of the light guide part 120 and the light-emitting component 130.

[0065] Refer to Figure 2 , Figure 4 and Figure 8In one embodiment, the light guide portion 120 includes a light guide body 121 and a plurality of limit arms 122 extending from the light guide body 121 toward the circuit board 131. The plurality of limit arms 122 are arranged at intervals along the circumference of the housing 110. The free ends of at least some of the limit arms 122 are bent toward the inner side surface of the housing 110 to form abutment arm sections 1221. Each abutment arm section 1221 is non-rotatably connected to the inner wall surface of the housing 110. In this way, the arrangement of the plurality of limit arms 122 can increase the contact area between the light guide portion 120 and the circuit board 131, thereby enhancing the stability of the light emitting component 130 during use. At the same time, the limit arms 122 arranged at intervals along the circumference of the housing 110 can also effectively prevent relative displacement between the light guide portion 120 and the circuit board 131. The design of the plurality of limit arms 122 can make the connection between the light guide portion 120 and the circuit board 131 more convenient. Since the limiting arms 122 have certain elasticity and buffering properties, the light guide 120 and the circuit board 131 can be protected from damage during the installation process. The design of multiple limiting arms 122 can also facilitate the removal and replacement of the light guide 120 or the circuit board 131. In addition, since the multiple limiting arms 122 can disperse the force, the fatigue degree of the light guide 120 and the circuit board 131 during use is reduced.

[0066] At the same time, since the limiting arm 122 has good buffering performance, it can also absorb external impact and vibration, thereby extending the service life of the light-emitting component 130. Each abutting arm segment 1221 is connected to the inner wall surface of the housing 110 in a non-rotatable manner. This design can accurately limit the position and angle of the light-guiding portion 120 to prevent it from rotating or moving, thereby ensuring the normal operation of the light-emitting component 130. During assembly, there is no need to additionally fix or adjust the light-guiding portion 120, and the assembly can be completed quickly, thereby improving production efficiency.

[0067] It should be noted that the structures of the plurality of limit arms 122 may be the same or different, and this application does not limit this.

[0068] Reference Figure 2 and Figure 3In one embodiment, each abutting end surface of each abutting arm section 1221 facing the circuit board 131 is convexly provided with an elastic rib 141, and each elastic rib 141 abuts against the circuit board 131. In this way, the provision of the elastic rib 141 can increase the contact area between the light guide 120 and the circuit board 131, thereby enhancing the stability of the light emitting assembly 130 during use. At the same time, the elastic rib 141 can also effectively prevent the relative displacement between the light guide 120 and the circuit board 131. The design of the elastic rib 141 can make the connection between the light guide 120 and the circuit board 131 more convenient. At the same time, since the elastic rib 141 has a certain elasticity and buffering performance, it can also protect the light guide 120 and the circuit board 131 from damage during the installation process. The design of the elastic rib 141 can also facilitate the disassembly and replacement of the light guide 120 or the circuit board 131. Since the elastic rib 141 can disperse the force, the fatigue degree of the light guide 120 and the circuit board 131 during use is reduced. At the same time, since the elastic ribs 141 have good buffering properties, they can also absorb external shocks and vibrations, thereby extending the service life of the light-emitting assembly 130 and the light-guiding portion 120. Since the elastic ribs 141 can support and stabilize the light-guiding portion 120, the light-guiding portion 120 can more efficiently irradiate light to the desired position, thereby improving the luminous efficiency.

[0069] It should be noted that, in one embodiment, the first end face includes an abutting end face, and in another embodiment, the abutting end face may also be the first end face. Specifically, the present application does not limit this.

[0070] Reference Figure 4 and Figure 5In one embodiment, the inner wall surface of the housing 110 is arranged in a stepped manner to form a stepped surface 111 arranged toward the circuit board 131, and a limiting space a is formed between the stepped surface 111 and the second end surface 1311 of the circuit board 131 facing the light guide portion 120, and a plurality of abutting arm sections 1221 are all installed in the limiting space a, and abut against the stepped surface 111 and the second end surface 1311 respectively. In this way, the relative position between the light guide portion 120 and the circuit board 131 can be accurately limited by the limiting space a between the stepped surface 111 and the second end surface 1311 of the circuit board 131 facing the light guide portion 120. This design ensures the accuracy and stability of the light-emitting component 130 during assembly and use. The plurality of abutting arm sections 1221 abut against the stepped surface 111 and the second end surface 1311 of the circuit board 131 respectively, which can effectively prevent the relative movement between the light guide portion 120 and the circuit board 131, thereby enhancing the stability of the light-emitting component 130 during use. By installing the abutting arm section 1221 in the limiting space a, installation and maintenance can be conveniently performed. Through the precise limiting design, it can be ensured that the light guide section 120 efficiently illuminates the light emitting assembly 130, thereby improving the light emitting efficiency. Since each abutting arm section 1221 is non-rotatably connected to the inner wall surface of the housing 110, there is no need to additionally fix or adjust the light guide section 120 during assembly, and assembly can be completed quickly, thereby improving production efficiency.

[0071] Reference Figure 6 and Figure 7 In one embodiment, the step surface 111 is provided with a plurality of limiting ribs 112, which are arranged at intervals along the circumference of the housing 110 and respectively abut against the limiting end faces of the plurality of abutting arm segments 1221 that are away from the circuit board 131. In this way, the arrangement of the limiting ribs 112 can further enhance the stability of the light-emitting component 130. The limiting ribs 112 abut against the abutting end faces of the plurality of abutting arm segments 1221, respectively, to prevent relative movement between the light-guiding portion 120 and the circuit board 131, and ensure the stability of the light-emitting component 130 during use. The limiting ribs 112 are arranged at intervals along the circumference of the housing 110, so that the light-guiding portion 120 and the circuit board 131 can be more conveniently aligned during the installation process, and quick assembly can be achieved. At the same time, due to the arrangement of the limiting ribs 112, the problem of difficulty in installing the light-guiding portion 120 caused by processing errors can be reduced. The design of the limiting ribs 112 can disperse the force between the light guide 120 and the circuit board 131, reduce the fatigue during use, and thus extend the service life of the light emitting assembly 130. The design of the limiting ribs 112 can support and stabilize the light guide 120, so that the light guide 120 can more efficiently irradiate light to the desired position, thereby improving the luminous efficiency.

[0072] Reference Figure 1 and Figure 2In one embodiment, a plurality of light-emitting parts 132 are provided, and the plurality of light-emitting parts 132 are arranged at intervals along the circumference of the housing 110. By providing a plurality of light-emitting parts 132, the total light-emitting area of ​​the light-emitting assembly 130 can be increased, thereby enhancing its light-emitting intensity and visual effect. This design can improve the light-emitting efficiency of the light-emitting assembly 130, and is suitable for application scenarios requiring high-brightness lighting. The plurality of light-emitting parts 132 are arranged at intervals along the circumference of the housing 110, which can create a more uniform and smooth lighting effect. This design can enhance visual comfort and improve lighting quality. By arranging the plurality of light-emitting parts 132 at intervals along the circumference of the housing 110, the stability of the light-emitting assembly 130 can be increased. When one of the light-emitting parts 132 fails, the other light-emitting parts 132 can still work normally, ensuring the stability and reliability of the entire light-emitting assembly 130. The provision of a plurality of light-emitting parts 132 makes installation and maintenance more convenient. During installation, all light-emitting parts 132 can be installed at the same time to improve assembly efficiency. When one of the light-emitting units 132 needs to be repaired or replaced, the operation can be performed separately without affecting the normal operation of other light-emitting units 132. The provision of multiple light-emitting units 132 can avoid the glare caused by concentrated lighting, reduce damage to the eyes, and improve safety of use. By providing multiple light-emitting units 132, the light-emitting assembly 130 can be adapted to different application scenarios. For example, in places where local lighting or lighting of a specific shape is required, better lighting effects can be achieved by adjusting the number and arrangement of the light-emitting units 132.

[0073] It should be noted that, in the embodiment of the present application, six light emitting units 132 are provided, and the six light emitting units 132 are spaced 60 degrees apart, so that a uniform lighting effect can be provided, the visual effect can be enhanced, the indication function can be improved, the production efficiency can be improved, and the maintenance can be facilitated. Such a setting can be flexibly adjusted and optimized according to the needs of actual applications to achieve better performance and effects.

[0074] In one embodiment, the housing 110 and the light-emitting portion 132 are integrally formed, so that the assembly steps of the light-guiding portion 120 and the housing 110 are reduced, and the assembly efficiency of the light-emitting knob structure 100 is improved. The integrally formed setting can avoid the independent processing and assembly of the housing 110 and the light-emitting portion 132, thereby simplifying the production process and reducing the production cost. By integrating the housing 110 and the light-emitting portion 132 together, their integrity and stability can be enhanced. This design can ensure the reliability of the light-emitting component 130 during use and reduce the failure rate. The integrally formed setting makes the structural design of the light-emitting component 130 more reasonable and compact. This design can improve the performance of the light-emitting component 130 and make it more beautiful. The integrally formed setting can avoid assembly errors or omissions that may be caused by independent components, thereby improving the safety of use. The integrally formed setting of the housing 110 and the light-emitting portion 132 can better protect the light-emitting component 130 and improve the waterproof performance of the light-emitting knob structure 100. The light-emitting component 130 with an integrally formed setting can better utilize energy, so that the energy conversion efficiency is improved, thereby reducing energy consumption. The one-piece molding arrangement makes it easier to maintain the light emitting assembly 130. When the light emitting unit 132 needs to be repaired or replaced, it can be easily removed from the housing 110 and replaced without disassembling the entire assembly.

[0075] It should be noted that when the housing 110 and the light-emitting portion 132 are integrally formed, the housing 110 and the light-emitting portion 132 can be molded by two-color injection molding, so that the integrally molded housing 110 and the light-emitting portion 132 have the function of protecting the housing 110 and also have the function of guiding light, that is, two-color injection molding can integrate multiple functions into one plastic part, so that design space can be saved and the number of parts can be reduced. Through two-color injection molding, plastics of different materials or colors can be used to manufacture the housing 110 and the light-emitting portion 132, so that the utilization of materials can be optimized and efficiency can be improved without increasing production costs. Two-color injection molding technology can mold multiple parts at one time, which can not only reduce production steps, but also improve production efficiency. Two-color injection molding can also improve the quality of the product, because this method can reduce the movement or vibration of parts, thereby reducing the damage rate of the product during use. By using different colors or materials, two-color injection molding can make the product more beautiful and more attractive.

[0076] In addition, in other embodiments, the interior of the shell 110 can also be made into a light-emitting structure as a whole, so that the light-emitting knob structure 100 can be self-luminous. In this way, the structure of the light-emitting knob structure 100 is simplified, making the structure of the light-emitting knob structure 100 compact and small, and the number of parts of the light-emitting knob structure 100 can be reduced, thereby reducing the manufacturing cost of the light-emitting knob structure 100 and simplifying the production process requirements.

[0077] Reference Figures 6 to 8In one embodiment, the light guide 120 and the inner wall surface of the housing 110 are connected by a rotation-stopping structure, which includes a rotation-stopping protrusion 151 and a rotation-stopping groove 152 matched with the rotation-stopping protrusion 151. One of the rotation-stopping protrusion 151 and the rotation-stopping groove 152 is provided on the light guide 120, and the other is provided on the housing 110. In this way, the design of the rotation-stopping structure can effectively prevent the rotation between the light guide 120 and the housing 110, thereby ensuring the stability of the light emitting assembly 130 during use. The cooperation of the rotation-stopping protrusion 151 and the rotation-stopping groove 152 can limit the relative rotation of the light guide 120 and the housing 110, and avoid the performance degradation or damage of the light emitting assembly 130 caused by the rotation. Through the design of the rotation-stopping structure, the light guide 120 and the housing 110 can be more conveniently aligned and connected during assembly. The cooperation of the rotation-stopping protrusion 151 and the rotation-stopping groove 152 can make the assembly process simpler and faster. The design of the anti-rotation structure can ensure the correct position and angle of the light guide 120 in the light-emitting assembly 130, so that the light can be irradiated to the desired position more efficiently, thereby improving the light-emitting efficiency. The design of the anti-rotation structure can make the structure of the light-emitting assembly 130 more compact and reasonable, thereby reducing energy consumption and improving energy efficiency. The design of the anti-rotation structure makes the maintenance of the light-emitting assembly 130 more convenient. When the light guide 120 needs to be repaired or replaced, it can be easily disassembled and replaced by cooperating with the anti-rotation protrusion 151 and the anti-rotation groove 152 without disassembling the entire assembly.

[0078] In a second aspect, the present application also provides a vehicle, the vehicle comprising the luminous knob structure 100 as described above.

[0079] According to the vehicle of the present application, since the light-emitting part 132 is installed on the circuit board 131, and the circuit board 131 is connected to the housing 110, the position of the light-emitting part 132 is limited. Under the support of the circuit board 131, the light-guiding part 120 is easy to install and operate, and the self-luminescence of the knob structure can be realized, the visibility, practicality and uniqueness of the light-emitting knob structure 100 are improved, the operation is simplified and energy is saved. In addition, the light-guiding part 120 is connected to the housing 110 so that the light emitted by the light-emitting part 132 is guided and diffused by the light-guiding part 120, and a uniform and soft lighting effect can be formed in the light-transmitting area. In addition, the lighting effect of the light-emitting part 132 can be kept stable during rotation, while avoiding glare and dazzling. Since the light guide portion 120 is directly in contact with the circuit board 131, the structural layout of the light guide portion 120 and the light-emitting component 130 is compact, which can reduce the volume of the light-emitting knob structure 100 to a certain extent, and can reduce the number of parts of the light-emitting knob structure 100, thereby reducing the manufacturing cost of the light-emitting knob structure 100 and simplifying the production process requirements.
