[0018] The present utility model provides an adjustment knob structure 100.
[0019] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the adjustment knob structure 100 includes a main body assembly 1 and a panel 2. The main body assembly 1 includes a housing 11 and a light source 12, and the light source 12 is disposed inside the housing 11; the panel 2 is connected to the housing 11, the panel 2 is provided with a first light collecting groove 21, a light transmissive area 211 is formed on the bottom wall of the first light collecting groove 21, and the light emitted by the light source 12 passes through the light transmissive area 211 and is concentrated by the side wall of the first light collecting groove 21.
[0020] In the technical solution of the present utility model, the light emitted by the light source 12 is projected onto the light transmissive area 211 to make the light transmissive area 211 transmissive, and the side wall of the first light collecting groove 21 plays a certain restrictive role in the direction of light propagation, so that the light can only be scattered along the notch of the first light collecting groove 21 (i.e., the specified direction), so that the light can be more concentrated in the first light collecting groove 21, making the light look brighter and more concentrated. And when the light passes through the light transmissive area 211 on the bottom wall of the first light collecting groove 21, it can make the side wall of the entire first light collecting groove 21 produce a surrounding light effect, enhancing the three-dimensional sense and dynamic sense in vision; this structural setting can significantly improve the light collecting effect and thus improve the overall light emitting effect of the structure. The light source 12 can be an LED lamp bead or a circular lamp strip, and the present utility model does not limit this; the panel 2 is usually a silicone panel 2, a light shielding layer is sprayed on the silicone panel 2, and the light shielding layer is removed at the position corresponding to the light transmissive area 211 to achieve the light transmissive of the light transmissive area 211 and the non-light transmissive of other areas.
[0021] To further improve the light-emitting effect, in an embodiment of the present utility model, the side wall of the first light-condensing groove 21 is arranged in an arc shape and is recessed outward from the center of the first light-condensing groove 21. By arranging the side wall of the first light-condensing groove 21 in an arc shape and recessing it outward, the light-gathering effect of light can be effectively improved, and the scattered light can be better concentrated and guided to the area that needs illumination or indication, improving the utilization efficiency of the light source 12; the recessed arrangement can reduce the loss of light during transmission. Generally, if light propagates through the edge of a plane, it may be scattered into the surrounding environment, while the recessed arrangement can more effectively control the propagation path of light and reduce the loss of light propagation, thereby improving the light-emitting effect.
[0022] Furthermore, in an embodiment of the present utility model, the included angle between the bottom wall of the first light-condensing groove 21 and the tangent line at any point on the side wall of the first light-condensing groove 21 is A, where 90° ≤ A ≤ 120°. By appropriately designing the included angle A, the uniform distribution of light in the first light-condensing groove 21 can be ensured, improving the light uniformity; a suitable included angle A can reduce the number of reflections of light in the first light-condensing groove 21, reduce light loss, contribute to improving the energy efficiency ratio of the light source 12, and reduce energy waste.
[0023] To further improve the light-condensing effect, please refer to Figure 1 , in an embodiment of the present utility model, the panel 2 is provided with a second light-condensing groove 22 along the circumferential direction of the panel 2, and the bottom wall of the second light-condensing groove 22 forms the first light-condensing groove 21. The light emitted by the light source 12 is projected onto the light-transmitting area 211, so that the light-transmitting area 211 realizes light transmission. Most of the light passing through the light-transmitting area 211 is concentrated in the first light-condensing groove 21, and part of the light is scattered into the second light-condensing groove 22 after passing through the first light-condensing groove 21, making the entire second light-condensing groove 22 produce a surrounding light effect, realizing the effect of continuous light condensation, improving the utilization rate of light, and further greatly improving the light-condensing effect and light-emitting effect of the overall adjusting knob structure 100; in another embodiment, a plurality of first light-condensing grooves 21 are evenly spaced on the panel 2, and the second light-condensing groove 22 is arranged around the plurality of first light-condensing grooves 21, and part of the light is scattered into the second light-condensing groove 22 after passing through the plurality of first light-condensing grooves 21, forming a bright light circle on the side wall of the second light-condensing groove 22.
[0024] Specifically, in an embodiment of the present utility model, the side wall of the second light condensing groove 22 is arranged in an arc shape and is recessed outward from the center of the second light condensing groove 22. By arranging the side wall of the second light condensing groove 22 in an arc shape and recessed outward, the light concentration effect can be effectively improved, the light scattered from the first light condensing groove 21 can be better concentrated, and the utilization efficiency of the light source 12 can be improved; the recessed arrangement can reduce the loss of light during transmission, more effectively control the propagation path of light, reduce the loss of light propagation, and thus improve the light concentration and light emission effects.
[0025] In an embodiment of the present utility model, the included angle between the bottom wall of the second light condensing groove 22 and the tangent line at any point on the side wall of the second light condensing groove 22 is B, where 90° ≤ B ≤ 120°. By appropriately designing the included angle B, the uniform distribution of light in the second light condensing groove 22 can be ensured, and the light uniformity can be improved; the appropriate included angle B can reduce the number of reflections of light in the second light condensing groove 22, reduce light loss, contribute to improving the energy efficiency ratio of the light source 12, reduce energy waste, enable the light to be better focused and diffused in the second light condensing groove 22, and enhance the visibility of the knob at different angles and lighting conditions.
[0026] Please refer to Figures 1 to 3, in an embodiment of the present utility model, the main body assembly 1 includes a knob main body 13, a PCB board 14, and a plurality of the light sources 12. The knob main body 13 passes through the bottom walls of the housing 11 and the first light condensing groove 21, and the knob main body 13 is exposed at the notch of the first light condensing groove 21. The light-transmitting area 211 is arranged around the knob main body 13; a plurality of light guiding through holes 111 are spaced apart in the circumferential direction of the knob main body 13 on the housing 11. The plurality of light sources 12 are spaced on the PCB board 14 and electrically connected to the PCB board 14. Each light source 12 corresponds to one of the light guiding through holes 111. Each light guiding through hole 111 accurately guides the light emitted from the light source 12, reducing the reflection and scattering of the light inside the knob structure, thereby reducing the loss and non-uniformity of the light; the paired design of each light guiding through hole 111 and each light source 12 can maximize the utilization of light transmission, avoiding the absorption or reflection of the light by the obstacles or reflecting surfaces inside the adjustment knob structure 100, thereby improving the luminous efficiency and brightness; the independent design of a single light guiding through hole 111 and the light source 12 can reduce the risk of affecting other parts due to the failure of one component. This separated design can increase the reliability and durability of the structure, reducing the need for maintenance and replacement; the knob main body 13 and the first light condensing groove 21 can be provided with one or multiple. When multiple are provided, each knob main body 13 corresponds to one of the first light condensing grooves 21. Different knob main bodies 13 can be used to adjust different parameters, such as the volume, pitch, and equalizer settings in an audio device, or the frequency, amplitude, etc. in an experimental instrument. Each knob main body 13 represents an independent control channel, allowing the user to adjust multiple parameters simultaneously to achieve precise adjustment and the best user experience.

[0028] Please refer to Figure 1, in an embodiment of the present utility model, a second limiting groove 113 is formed by inward depression of the bottom wall of the first limiting groove 112, the bottom wall of the first light collecting groove 21 protrudes towards the housing 11, and the bottom wall of the first light collecting groove 21 is limited within the second limiting groove 113; a positioning post 23 is formed on the side of the panel 2 facing the housing 11, and a positioning groove 114 is formed on the side of the housing 11 facing the panel 2, and the positioning post 23 is inserted into the positioning groove 114. The bottom wall of the first light collecting groove 21 is clamped and limited through the second limiting groove 113 to ensure accurate positioning between the panel 2 and the housing 11 and achieve a stable connection; by inserting the positioning post 23 into the positioning groove 114, accurate positioning between the panel 2 and the housing 11 can be ensured, avoiding deviation or instability during assembly, and improving the assembly accuracy and structural stability of the product; the design of the positioning post 23 and the positioning groove 114 can prevent the panel 2 from moving or falling off due to external force or accident during use, thereby reducing the risk of misoperation or damage.
