[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] In the present disclosure, unless otherwise stated, directional words such as "first direction, second direction, third direction" refer to three directions that intersect each other, and specifically can be three directions that are perpendicular to each other. For example, Figure 3 As shown; the directional words used such as "inside and outside" refer to the inside and outside of the specific structural outline, and the terms used such as "first and second" are only used to distinguish one element from another element, and do not have order and importance.

[0038] Reference Figures 1 to 3As shown, the present disclosure provides an icon indication structure 100, which includes a light-emitting component 1, a light guide component 2, a light diffuser (not shown) and a light-shielding component 3, wherein a light-incoming surface 201 of the light guide component 2 is located on a light-emitting side of the light-emitting component 1, the light diffuser is evenly arranged in the light guide component 2, and the light-shielding component 3 is arranged on a light-emitting surface 202 of the light guide component 2; wherein the light-shielding component 3 includes a light-shielding area 301 and an icon light-transmitting area 302, the light-shielding area 301 can limit light from being emitted from the light-emitting surface 202, and the icon light-transmitting area 302 can allow light to be emitted from the light-emitting surface 202.

[0039] In the above technical scheme, since the light-incoming surface 201 of the light-guiding component 2 is arranged on the light-emitting side of the light-emitting component 1, the light emitted by the light-emitting component 1 can enter the light-guiding component 2 through the light-incoming surface 201, and then the light can be emitted to the light-emitting surface 202. Since the light-shielding component 3 is arranged on the light-emitting surface 202 of the light-guiding component 2 and includes a light-shielding area 301 and an icon light-transmitting area 302, the light in the area where the light-emitting surface 202 and the light-shielding area 301 are opposite to each other cannot be emitted, and the light in the area where the light-emitting surface 202 and the icon light-transmitting area 302 are opposite to each other can be emitted. By designing the shape of the icon light-transmitting area 302, different luminous indication effects can be achieved. By evenly arranging the light diffuser in the light guide 2, the light can be scattered more in the light guide 2, making the light output more uniform. In addition, by adding the light diffuser, the light can be emitted at various angles, which can increase the light-emitting area of ​​the light-emitting surface. It is not necessary to make the light-emitting component 1 far away from the light-input surface 201 of the light guide 2 to achieve large-area light emission, utilizing the compact structural design.

[0040] Optionally, refer to Figure 2 As shown, the shading member 3 may include a base layer 31, an intermediate layer 32 and a surface layer 33; the base layer 31 covers the surface of the light emitting surface 202 and is light-transmissive, and the base layer 31 includes a first base portion 311 and a second base portion 312 which are connected to each other, the first base portion 311 is located in the shading area 301, and the second base portion 312 is located in the icon light-transmissive area 302; the intermediate layer 32 is arranged in the shading area 301, and covers the side of the base layer 31 away from the light guide 2 and is not light-transmissive, and the surface layer 33 covers the side of the intermediate layer 32 away from the base layer 31; wherein the intermediate layer 32, the surface layer 33 and the second base portion 312 jointly define the icon groove 30.

[0041] In this embodiment, in the light-shielding area 301, the first base portion 311 of the base layer 31 covers the surface of the light-emitting surface 202, and the middle layer 32 covers the side of the base layer 31 away from the light guide 2 and is not light-transmissive, so the light cannot be emitted from the light-shielding area 301, and the surface layer 33 covers the side of the middle layer 32 away from the base layer 31, which can play a good protective and decorative role. In the icon light-transmitting area 302, the second base portion 312 of the base layer 31 covers the surface of the light-emitting surface 202, and the base layer 31 can be light-transmissive, so the light can be emitted from the icon light-transmitting area 302. However, the present disclosure does not limit the specific structure of the light-shielding member 3. In addition, from the perspective of technology, in the early stage of the process, the base layer 31, the middle layer 32 and the surface layer 33 of the light shielding member 3 can be completely laid on the light shielding area 301 and the icon light transmission area 302. In the later stage of the process, the middle layer 32 and the surface layer 33 of the icon light transmission area 302 can be removed to ensure that light can be emitted from the icon light transmission area 302. As for the specific removal method, for example, the middle layer 32 and the surface layer 33 of the icon light transmission area 302 can be removed by laser engraving, for example, referring to Figure 1 As shown, the laser lamp 5 emits laser for engraving, thereby forming the above-mentioned icon groove 30, but the present disclosure does not limit the forming method of the icon groove 30.

[0042] In one embodiment, referring to Figure 2 As shown, the intermediate layer 32 may include a first intermediate layer 321 and a second intermediate layer 322, wherein the first intermediate layer 321 covers a side of the base layer 31 away from the light guide 2 and is opaque, and the second intermediate layer 322 covers a side of the first intermediate layer 321 away from the base layer 31 and is opaque. By setting the intermediate layer 32 as the first intermediate layer 321 and the second intermediate layer 322, and both the first intermediate layer 321 and the second intermediate layer 322 are opaque, the light shielding effect can be further improved.

[0043] For example, the light guide 2 can be made of a translucent milky white material, the base layer 31 can include a white primer, the first intermediate layer 321 includes a gray primer, the second intermediate layer 322 includes a colored paint, and the surface layer 33 includes a topcoat. However, the present disclosure does not limit the specific materials of the light guide 2, the base layer 31, the first intermediate layer 321, the second intermediate layer 322 and the surface layer 33, nor does it limit the color of each paint layer, which can be selected according to needs. For example, the above-mentioned colored paint can be a gray paint that is darker than the first intermediate layer 321. In addition, by setting the base layer 31 as a white primer, even if the light-emitting element 1 does not emit light, it can display a bright white decorative effect in the marked light-transmitting area 302. Of course, the present disclosure does not limit the specific color of the base layer 31, which can be selected according to needs.

[0045] In this embodiment, the button back cover 4 can effectively block the mounting groove 210, improve the sealing performance of the mounting groove 210, and also prevent light from leaking out. For example, the button back cover 4 can be made of opaque plastic, and the button back cover 4 can be connected to the light guide 2 by bonding or detachably connected to the light guide 2 by fasteners. In addition, the above-mentioned light-incoming surface 201 can be a curved surface, thereby increasing the angle of light entering. In addition, the icon indication structure 100 is not limited to being constructed as a button structure, and can be constructed as any structure that requires icon indication.

[0046] In other embodiments, the light guide body 21 is configured as a light guide block, the surface of the light guide block is configured as a light emitting surface 202 and includes a first button surface 2021 and a second button surface 2022 arranged back to back along a first direction A, the light shading member 3 is arranged on the first button surface 2021 and the second button surface 2022, and the icon light-transmitting area 302 is arranged on the first button surface 2021 and / or the second button surface 2022.
