[0029] The utility model will be further described in detail below in combination with the drawings.

[0030] Please refer to Figures 1 to 4The embodiment discloses a knob structure which comprises a transparent shell 1, a knob body 2, a decorative ring 3 and a circuit board 4. The transparent shell 1 comprises a shaft part 11 which is provided with a mounting hole 113 and a light guide gear ring 1131. The knob body 2 is rotationally connected to the mounting hole 113. The decorative ring 3 is sleeved on the shaft part 11. The circuit board 4 is connected to the transparent shell 1 and is provided with a plurality of light source lamps 41 which are distributed around the circuit board 4 and are opposite to the side of the shaft part 11 away from the decorative ring 3. The light of the light source lamps 41 can reach the decorative ring 3 after being refracted by the shaft part 11 and the light guide gear ring 1131.

[0031] The shaft part 11 and the light guide gear ring 1131 are both transparent, so that the light can penetrate and be refracted by the shaft part 11 and the light guide gear ring 1131. Specifically, the light guide gear ring 1131 can realize the functions of refraction and light collection, thereby enhancing the brightness and uniformity of the light. Thus, the light of the plurality of light source lamps 41 distributed around the circuit board 4 can be uniformly irradiated on the decorative ring 3 after being refracted by the shaft part 11 and the light guide gear ring 1131, which can avoid the problem of uneven light distribution and make the bright part of the decorative ring 3 present a more uniform and soft luster.

[0032] As shown in Figs. Figure 3 and Figure 4 Specifically, in the embodiment, the first direction is defined as the axial direction of the mounting hole 113, and the second direction is perpendicular to the first direction. The shaft part 11 has a first side wall 111 and a second side wall 112, and the mounting hole 113 has a third side wall 1133. The first side wall 111 is away from the decorative ring 3. The second side wall 112 and the third side wall 1133 are both inclined to the first direction. The second side wall 112, the first side wall 111 and the light source lamps 41 are arranged in the first direction in sequence. The second side wall 112 and the light guide gear ring 1131 are oppositely arranged in the second direction. The light guide gear ring 1131 and the third side wall 1133 are oppositely arranged in the first direction. The third side wall 1133 and the decorative ring 3 are oppositely arranged in the second direction. Thus, the light of the light source lamps 41 first passes through the first side wall 111 of the shaft part 11 and then reaches the second side wall 112. Due to the inclination angle of the second side wall 112, the light is refracted. The refracted light enters the light guide gear ring 1131. The light guide gear ring 1131 further refracts and collects the light. The collected light reaches the third side wall 1133. The third side wall 1133 also has an inclination angle and refracts the light again. Finally, the light is refracted from the third side wall 1133 to the decorative ring 3, so that the decorative ring 3 presents a uniform and soft luster. Thus, the inclined second side wall 112 and the third side wall 1133 and the light guide gear ring 1131 with a special tooth shape realize the uniform propagation of the light from the light source lamps 41 to the decorative ring 3. This design not only solves the problem of uneven light distribution but also improves the visual effect and aesthetic degree of the product.

[0033] Specifically, the first direction can refer to the e1 direction in Figure 3 , and the second direction can refer to the e2 direction in Figure 3 ; more specifically, Figure 4 The dotted line between the light source lamp 41 and the decorative ring 3 in

The design of the inclined side wall 1132 allows the light to be further refracted and propagate in a specific direction, and the design of the inclined side wall 1132 can allow light from different directions to be focused on specific areas, thereby enhancing the brightness and visual effect of these areas. Specifically, in the present embodiment, the light is focused on the third side wall 1133, which in turn refracts the light to the decorative ring 3. In addition, due to the possible small gaps or gaps between the teeth, these gaps and gaps can also produce certain scattering or diffraction effect on the light, thereby further enhancing the uniformity and soft spotlight effect of the light.

[0035] As shown in Figure 2 , Figure 3 and Figure 4 , preferably, in the present embodiment, the knob structure further comprises a bracket 5 connected to the transparent shell 1, and the circuit board 4 is fixed to the bracket 5, and the bracket 5 forms a side light that surrounds and shields the light source lamp 41.

In this way, the design of the plate part 12 not only enhances the overall structural stability of the transparent shell 1, but also provides convenience for the installation of other components, the light shielding piece 6 is arranged in the mounting groove 121, the main function of the light shielding piece 6 is to shield or absorb unnecessary light from the light source lamp 41, so as to prevent these light from interfering with the surrounding area or causing light leakage, and by placing the light shielding piece 6 in the mounting groove 121, it can be ensured that it is tightly attached to the transparent shell 1, thereby effectively playing its light shielding role, at the same time, this design also makes the installation and disassembly of the light shielding piece 6 relatively simple.

[0038] It should be noted that in some other embodiments, the mounting groove 121 can form a full surrounding to the shaft part 11, the shape and size of the mounting groove 121 can be set according to actual needs, which is not limited herein.

[0039] As shown in Figure 3 , Figure 4 and Figure 6As shown, specifically in this embodiment, the plate portion 12 is also provided with a connecting groove 122 surrounding the shaft portion 11, and the bracket 5 is partially engaged within the connecting groove 122. Thus, a connecting groove 122 surrounding the shaft portion 11 is added to the plate portion 12. The shape and size of this connecting groove 122 typically match the corresponding part of the bracket 5 to ensure that the bracket 5 can be securely engaged within the groove. Furthermore, on the one hand, the connecting groove 122 is designed to surround the shaft portion 11, meaning that the bracket 5 can fit tightly around the shaft portion 11 when engaged, thus providing additional support and stability. On the other hand, part of the bracket 5's structure is designed to engage within the connecting groove 122.
