[0033] In existing technologies, illuminated knobs offer only a single, monochromatic lighting effect, lacking dynamism and depth, and failing to meet the demands of modern products for personalized and ambient lighting. Therefore, how to create illuminated knobs with unique lighting effects to satisfy users' personalized and diverse needs has become a key issue requiring attention from those skilled in the art.

[0034] As described below, some exemplary embodiments of this disclosure provide an illuminated knob and the vehicle in which it is applied to address the aforementioned problems.

[0035] refer to Figure 1 and Figure 2 An exemplary illuminated knob 100 according to an embodiment of the present disclosure is shown, wherein, Figure 1This is a cross-sectional view of the illuminated knob 100. Figure 2 This is an exploded view of the luminous knob 100. As shown, the luminous knob 100 includes: a knob body 102, a base 104, a light-emitting part 106, and a light-guiding part 108. The base 104 is rotatably connected to the knob body 102. The light-emitting part 106 is disposed between the knob body 102 and the base 104. The light-guiding part 108 is disposed between the light-emitting part 106 and the knob body 102.

[0036] The knob body 102 serves as the user's direct operating interface. Suitable materials include acrylic (polymethyl methacrylate, PMMA), polycarbonate (PC), optical glass, crystal, transparent ABS resin (acrylonitrile-butadiene-styrene copolymer), MS resin (methyl methacrylate-styrene copolymer), etc., which can both transmit and diffuse light. The base 104 acts as the core structural carrier of the knob, responsible for fixing the entire knob and its integrated circuits and electronic components. The light-emitting part (usually an LED) is mounted on the base as the light source. The light guide part guides the light emitted by the light-emitting part, ultimately achieving the desired luminous indication effect.

[0037] In some examples, the light guide 108 includes a semi-reflective layer 1082. The semi-reflective layer 1082 is positioned between the light-emitting part 106 and the knob body 102. Furthermore, the knob body 102 can rotate the semi-reflective layer 1082 relative to the light-emitting part 106. The rotation of the semi-reflective layer 1082 relative to the light-emitting part 106 causes the light path emitted by the light-emitting part 106 to continuously change with the rotation of the semi-reflective layer 1082, thereby allowing the light-emitting knob to present a dynamically changing kaleidoscope-like light effect.

[0038] The semi-reflective and semi-transparent layer 1082 can reflect a portion of the incident light back and transmit a portion of it. It should be noted that this disclosure does not limit the ratio of reflectivity to transmittance of the semi-reflective and semi-transparent layer. For example, the ratio of reflectivity to transmittance can be 30%:70%, or 50%:50%, or 80%:20%, etc.

[0039] In some examples, the semi-reflective layer 1082 can be achieved by an extremely thin metal plating (such as silver or aluminum) or a dielectric film of a certain thickness (such as silicon dioxide, silicon nitride, titanium oxide, or magnesium fluoride).

[0040] refer to Figure 3In some examples, a semi-reflective layer 1082 is deployed on the inner surface of the knob body 102, so that the knob body 102 can drive the semi-reflective layer 1082 to rotate relative to the light-emitting part 106. As a result, the light path of the light emitted by the light-emitting part 106 will change with the rotation of the semi-reflective layer 1082, and the light-emitting knob can present a dynamically changing light effect.

[0041] refer to Figure 4 and Figure 5 In some examples, the surface of the semi-reflective and semi-permeable layer 1082 can be a plane, a curved surface, or a pyramidal surface (e.g., Figure 4 As shown). A curved surface can be a smooth surface or an uneven surface (such as...). Figure 5 (As shown). Different surface shapes can produce different luminous pattern transformation effects, increasing the randomness of the dynamic changes in the pattern and enhancing the three-dimensional depth effect. This disclosure can further improve the randomness of the light effect presented when the knob is rotated by increasing the complexity of the surface of the semi-reflective and semi-transparent layer.

[0042] When the user operates the luminous knob and rotates the knob body 102, the knob body will cause the semi-reflective layer 1082 to rotate relative to the light-emitting part 106 and the base 104. This causes the light emitted by the light-emitting part 106 to be reflected and transmitted through the semi-reflective layer 1082, and then transmitted out through the knob body 102. As the semi-reflective layer 1082 rotates, the light path of the light emitted by the light-emitting part 106 will change accordingly, and the luminous knob can present a dynamically changing light effect.

[0043] In some examples, the light guide 108 also includes a light-transmitting texture layer 1084, which is disposed between the light-emitting part 106 and the semi-reflective layer 1082. The light-transmitting texture layer 1084 can reflect, transmit, and / or scatter the light emitted by the light-emitting part once or multiple times through its texture or pattern.

[0044] When the light emitted by the light-emitting part 106 passes through the light-transmitting area of ​​the light-transmitting texture layer 1084, part of the light passes through the semi-reflective layer 1082, and part of the light is reflected by the semi-reflective layer 1082 to the bottom reflective layer (e.g., a total reflection layer with a high reflection probability) of the light-transmitting texture layer 1084, and then reflected again to the semi-reflective layer 1082. After multiple transmissions and reflections, the light disappears, forming a light-emitting pattern with depth of field.

[0045] In some examples, the translucent texture layer 1084 is combined with the light-emitting part 106, for example, it can be deployed on the upper surface of the light-emitting part 106. When the knob body rotates, it causes the semi-reflective layer 1082 to rotate relative to the translucent texture layer 1084 and the light-emitting part 106. In other words, when the knob body 102 rotates, the light-emitting part 106 and the translucent texture layer 1084 remain stationary, and the knob body 102 causes the semi-reflective layer 1082 to rotate. The rotation of the semi-reflective layer 1082 causes a change in the texture of the light guide part 108, and the reflection path of the light emitted by the light-emitting part 106 also changes accordingly, so that the light-emitting knob can present a dynamically changing light effect.

[0046] In other examples, the translucent texture layer 1084 is integrated with the knob body 102. When the knob body 102 rotates, the translucent texture layer 1084 rotates accordingly, and the luminous pattern forms a dynamically changing pattern, producing a dynamic depth-of-field three-dimensional luminous effect. In some embodiments, the semi-reflective and semi-transparent layer 1082 can be deployed on the upper surface of the translucent texture layer 1084. The semi-reflective and semi-transparent layer 1082 and the translucent texture layer 1084 are a single unit, and the knob body 102 can drive the semi-reflective and semi-transparent layer 1082 and the translucent texture layer 1084 to rotate together. In other words, when the knob body 102 rotates, the luminous part 106 remains stationary, and the knob body 102 drives the semi-reflective and semi-transparent layer 1082 and the translucent texture layer 1084 to rotate. The rotation of the semi-reflective layer 1082 and the translucent texture layer 1084 results in richer variations in the texture of the light guide 108, and consequently, richer variations in the reflection path of the light emitted from the light-emitting part 106, allowing the luminous knob to present dynamic, depth-of-field lighting effects. The rotation of the translucent texture layer 1084 provides the luminous knob with lighting effects that are more varied and more random.

[0047] In some examples, the translucent texture layer 1084 can scatter light through its frosted surface, creating a soft-light effect. In some examples, the translucent texture layer 1084 can disperse light into iridescent colors through an etched diffraction grating. In some examples, the translucent texture layer 1084 can control the light emission angle through a microprism array. In some examples, the translucent texture layer 1084 can adjust the lighting effect of the illuminated knob through translucent patterns printed on it.

[0048] In some examples, the upper and / or lower surfaces of the translucent texture layer 1084 are reflective layers, used to reflect the light reflected by the semi-reflective and semi-transparent layer back again, achieving a richer depth-of-field effect through multiple reflections.

[0049] like Figure 1As shown, the lower surface 10842 of the translucent texture layer 1084 is a reflective layer, which can be a total reflection layer or a semi-reflective layer. Its working principle is explained as follows: the light emitted by the light-emitting part 106 is transmitted through the translucent texture layer 1084 to the semi-reflective layer 1082. The light reaching the semi-reflective layer 1082 is partially emitted through the semi-reflective layer 1082 and the knob body 102, and partially reflected back to the translucent texture layer 1084 by the semi-reflective layer 1082. Then it is reflected back to the semi-reflective layer 1082 by the lower surface 10842 of the translucent texture layer 1084. Then it continues to be partially transmitted and partially reflected on the semi-reflective layer 1082. This process is repeated many times to achieve the depth-of-field lighting effect.

[0050] refer to Figure 6 , Figure 7 and Figure 8 The structure of the illuminated knob will be further explained. Figure 6 The image shown is a cross-sectional view of an illuminated knob. Figure 7 The image shown is a visual rendering of an illuminated knob. Figure 8 This is a schematic diagram of the structure of the translucent texture layer. (Example:) Figures 6 to 8 As shown, in some examples, a semi-reflective layer 1082 is deployed on the inner surface of the knob body 102. In some examples, the semi-reflective layer 1082 has a textured surface, such as a pyramidal surface. In some examples, the surface of the translucent texture layer 1084 is provided with a translucent pattern 10844. In some examples, the upper and lower surfaces of the translucent texture layer 1084 have at least one reflective layer.

[0051] In some examples, the light-emitting part 106 is deployed at the bottom of the base 104. Further, in some examples, both the light-emitting part 106 and the light-guiding part 108 are deployed at the bottom of the base 104, that is, the light-emitting part 106 and the light-guiding part 108 are located between the lower surface of the knob body 102 and the upper surface of the base 104. The knob body 102 can drive the semi-reflective layer of the light-guiding part 108 to rotate, thereby continuously changing the light path of the light emitted by the light-emitting part 106, resulting in a dynamically changing light effect at the bottom of the luminous knob.

[0052] refer to Figure 9 In some examples, the light-emitting part 106 can be multiple point light sources distributed regularly or irregularly (e.g., multiple point light sources arranged in a matrix). When using multiple point light sources, the brightness is highest when the pattern is directly above the light source. As the pattern rotates with the knob body, and the light-emitting pattern shifts away from the light source, the brightness decreases instantaneously, creating a flickering light effect during rotation. (Reference) Figure 10 In other examples, the light-emitting part 106 can be a uniform surface light source (e.g., a COB surface light source), which can ensure that the brightness of the light-emitting pattern remains constant or gradually changes during pattern transformation. Figure 11 and Figure 12This is a visual representation of the knob's potential effects when rotated. Figure 12 This is a visual representation of multiple point light sources that are regularly distributed in the luminous part.

[0053] refer to Figure 13 The diagram shows an optical path diagram of an exemplary luminous knob according to an embodiment of the present disclosure. Figure 13 The arrows in the diagram indicate the direction of light propagation. The light emitted from the light-emitting part 106 is transmitted through the translucent texture layer 1084 to the semi-reflective layer 1082. Part of the light reaching the semi-reflective layer 1082 is emitted through the semi-reflective layer 1082 and the knob body 102, and part is reflected back to the translucent texture layer 1084 by the semi-reflective layer 1082. Then it is reflected back to the semi-reflective layer 1082 by the lower surface of the translucent texture layer 1084. The light continues to be partially transmitted and partially reflected on the semi-reflective layer 1082. This process is repeated multiple times to achieve a depth-of-field lighting effect.

[0054] refer to Figure 14 , Figure 15 and Figure 16 The diagram illustrates an exemplary translucent textured layer that is rotatable relative to a light-emitting portion according to an embodiment of the present disclosure. Figure 14 This is a schematic diagram showing the illuminated knob rotating from position A1 to position B1. Figure 15 This diagram illustrates the correspondence between the translucent texture layer and the light-emitting part at position A1, along with the corresponding optical path. Figure 16 This diagram illustrates the correspondence between the translucent texture layer and the light-emitting part at position B1, along with the corresponding optical path. Figures 14 to 16 As shown, when the knob body 102 rotates from position A1 to position B1, the translucent texture layer 1084 rotates along with it, while the light-emitting part 106 remains stationary. The translucent pattern 10844 rotates, causing the amount and direction of light passing through the pattern on the light-emitting part 106 to change. This results in a simultaneous change in the shape and brightness of the pattern presented by the knob, creating a dynamic visual effect. The light emitted by the light-emitting part 106 passes through the translucent texture layer 1084 to reach the semi-reflective layer 1082. Part of the light is transmitted through the knob body 102, while the other part is reflected and then reflected again by the reflective layer on the surface of the translucent texture layer 1084. Multiple reflections create a depth-of-field effect.

[0055] refer to Figure 17 , Figure 18 and Figure 19 The diagram illustrates an exemplary translucent textured layer that is non-rotatable relative to the light-emitting portion according to an embodiment of the present disclosure. Figure 17 This is a schematic diagram showing the illuminated knob rotating from position A2 to position B2. Figure 18 This diagram illustrates the correspondence between the translucent texture layer and the light-emitting part at position A2, along with the corresponding optical path. Figure 19 This diagram illustrates the correspondence between the translucent texture layer and the light-emitting part at position B2, along with the corresponding optical path. Figures 17 to 19 As shown, when the knob body 102 is rotated from position A2 to position B2, the light-emitting part 106 and the light-transmitting texture layer 1084 remain stationary. The texture of the semi-reflective and semi-transparent layer on the inner surface of the knob body 102 changes, and the light reflection path also changes. Therefore, rotating the knob body can make the light-emitting knob present a dynamically changing light effect.

[0056] refer to Figure 20 This diagram illustrates a schematic structure of an exemplary illuminated button according to an embodiment of the present disclosure. In this illuminated knob, a translucent textured layer 1084 is combined with a semi-reflective layer 1082 and a knob body 102. The knob body 102 can rotate the translucent textured layer 1084 and the semi-reflective layer 1082 together. Furthermore, the lower surface 10842 of the translucent textured layer 1084 is uneven and can be coated or laminated to form a reflective layer. A gap exists between the light-emitting part 106 and the translucent textured layer 1084.

[0057] refer to Figure 21 This diagram illustrates a schematic representation of an exemplary illuminated button according to an embodiment of the present disclosure. In this illuminated knob, a translucent textured layer 1084 is combined with a semi-reflective layer 1082 and a knob body 102. The knob body 102 can rotate the translucent textured layer 1084 and the semi-reflective layer 1082 together. Furthermore, the lower surface of the semi-reflective layer 1082 is uneven. A gap exists between the light-emitting portion 106 and the translucent textured layer 1084.

[0058] refer to Figure 22 This diagram illustrates a schematic structure of an exemplary illuminated button according to an embodiment of the present disclosure. In this illuminated knob, a translucent textured layer 1084 is coupled to a light-emitting portion 106, and a semi-reflective layer 1082 is coupled to a knob body 102. The knob body 102 can rotate the semi-reflective layer 1082, while the translucent textured layer 1084 and the light-emitting portion 106 remain stationary. Furthermore, the lower surface of the semi-reflective layer 1082 is uneven. A gap exists between the semi-reflective layer 1082 and the translucent textured layer 1084.

[0059] refer to Figure 23This diagram illustrates an exemplary luminous knob according to an embodiment of the present disclosure. The luminous knob includes a knob body 102, a base 104, a light-emitting part 106, and a light-guiding part 108. The base 104 is rotatably connected to the knob body 102. The light-emitting part 106 is disposed between the sidewall of the knob body 102 and the sidewall of the base 104. The light-guiding part 108 is disposed between the light-emitting part 106 and the sidewall of the knob body 102. The light-guiding part 108 includes a semi-reflective layer 1082. The semi-reflective layer 1082 is disposed between the light-emitting part 106 and the sidewall of the knob body 102. Furthermore, the knob body 102 can drive the semi-reflective layer 1082 to rotate relative to the light-emitting part 106. The rotation of the semi-reflective layer relative to the light-emitting part 106 causes the light path of the light emitted by the light-emitting part 106 to continuously change, resulting in a dynamically changing annular light effect on the sidewall of the luminous knob.

[0060] refer to Figure 24 , showed Figure 23 The diagram shows an enlarged view of the structure and optical path of region F of the illuminated knob. The arrows indicate the direction of light propagation. The light emitted from the light-emitting part 106 is transmitted through the translucent texture layer 1084 to the semi-reflective layer 1082. Part of the light reaching the semi-reflective layer 1082 is emitted through the semi-reflective layer 1082 and the knob body 102, and part is reflected back to the translucent texture layer 1084 by the semi-reflective layer 1082. Then, it is reflected back to the semi-reflective layer 1082 by the lower surface of the translucent texture layer 1084. The light continues to be partially transmitted and partially reflected on the semi-reflective layer 1082, and so on, to achieve a depth-of-field lighting effect.

[0061] This disclosure further provides a vehicle including a vehicle body and one or more luminous knobs as described above, the luminous knobs being disposed on the vehicle body. The implementation of this vehicle is similar to the implementation of the luminous knobs described above, and therefore will not be repeated here.

[0062] The luminous knob and its application vehicle disclosed herein utilize a special rotating structure design. The knob body drives a semi-reflective, semi-transparent layer to rotate relative to the light-emitting part, allowing the luminous knob to achieve dynamic changes in luminous patterns, resembling a kaleidoscope effect, when the light-emitting part emits light. Furthermore, this disclosure allows for different luminous effects by deploying the light-emitting part and / or light guide part on the bottom or sidewall of the luminous knob. Additionally, this disclosure further enhances the randomness of the light effect pattern by setting the surface of the light guide part, such as the semi-reflective, semi-transparent layer or the light-transmitting textured layer, to an uneven surface, thereby driving the rotation of the light-transmitting textured layer. Therefore, this disclosure effectively solves the technical problem of monotonous luminous effects in existing luminous knobs, helping to meet users' personalized needs for luminous knobs and vehicles.
