[0027] The following specific embodiments will further illustrate the present invention in conjunction with the above drawings. Detailed implementation manners

[0028] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to fully understand the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art belonging to the technical field of the present invention. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0031] It should be noted that in this specification, the expressions such as first and second are only used to distinguish one feature from another feature, and do not represent any limitation on the feature.

[0032] Please refer to Figures 1-6 , Figure 1 A power button device 100 provided for an embodiment of the present invention. The power button device 100 of the present invention can be used as a power switch 10 of an electronic device, such as a computer, a handheld mobile terminal, a server, etc.

[0033] The power button device 100 includes: a switch 10, a pressing part 20, a touch part 30 fixed to the pressing part 20, and a housing 40.

[0034] The touch part 30 can trigger the switch 10 to turn on or off the power of the electronic device. The switch 10 includes a receiving groove 12, and a light source 14 is arranged in the receiving groove 12. The light source 14 can be a light emitting diode.

[0035] The pressing part 20 is made of a light-transmitting material. The light-transmitting material can be a resin material such as polyimide (PI), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), or glass.

[0036] Please refer to Figures 2-4 , the pressing part 20 includes a pressing panel 22, a light guide part 24, and two oppositely arranged buckles 26.

[0037] The pressing panel 22 has a circular contour, which includes a bottom surface 220 facing the switch 10, a pressing surface 222 opposite to the bottom surface 220, and an outer side surface 224 connected to the pressing surface 222. The pressing surface 222 and the outer side surface 224 are respectively coated with a black light-blocking layer 226 to prevent light leakage. The black light-blocking layer 226 can be black paint.

[0038] The light guide portion 24 is perpendicularly connected to the bottom surface 220 and is disposed opposite to the center of the light source 14. The light guide portion 24 is in the shape of a flat plate and includes a light incident surface 240, two opposite first side surfaces 242, and a second side surface 244 connected to the first side surfaces 242. The second side surface 244 is also inclinedly connected to the light incident surface 240. The second side surface 244 is also coated with a black light-blocking layer 226 to prevent light leakage.

[0039] Please refer to Figure 5 , the light incident surface 240 is an inclined surface that extends obliquely from one end of the bottom surface 220 to the edge of the pressing panel 22. In this embodiment, the light guide portion 24 is triangular. Since the light incident surface 240 is an inclined surface, the distance between the inclined light incident surface 240 and the light source 14 changes continuously. Thus, the light entering the light incident surface 240 has different optical paths, and the effect of light homogenization can be achieved.

[0040] The buckle 26 extends from the edge of the bottom surface 220 in a direction away from the bottom surface 220. The buckle 26 is in the shape of an L, and the end of the buckle 26 includes a hook 260. The two hooks 260 are arranged facing each other.

[0041] The pressing surface 222 is provided with a receiving groove 228, the receiving groove 228 is disposed opposite to the light guide portion 24, and a transmissive indicating light bar 230 is provided in the receiving groove 228. The light beam emitted by the light source 14 enters the light guide portion 24 from the light incident surface 240. Since the pressing portion 20 is made of a light-transmissive material, the light beam in the light guide portion 24 can be transmitted to the pressing panel 22 and the indicating light bar 230. The indicating light bar 230 is used to indicate the on / off state of the computer switch 10.

[0042] When the power button device 100 is pressed, the light emitted by the light source 14 is transmitted through the transparent area in the receiving groove 228 to the indicating light bar 230, and the indicating light bar 230 will emit light to indicate that the electronic device is turned on. Since the light incident surface 240 is an inclined surface, the light guide portion 24 can achieve light homogenization, and the light beam emitted from the indicating light bar 230 is relatively uniform, and the situation where the brightness of the central area is inconsistent with that of the edge area will not occur.

[0043] The touch part 30 is a non-closed circular cylindrical structure, and the touch part 30 is formed of a non-light-transmitting material. The touch part 30 includes an opposite top end 32 and a bottom end 34, and a peripheral wall 36 connecting the top end 32 and the bottom end 34. The peripheral wall 36 includes two oppositely arranged card slots 301 and a slot 303 located between the two card slots 301.

[0044] In this embodiment, the peripheral wall 36 includes an opposite inner surface 305 and an outer surface 307. The card slot 301 is opened from the top end 32 and extends towards the bottom end 34, but does not extend to the bottom end 34, and the card slot 301 is opened from the outer surface 307 towards the inner surface 305. A latching hole 309 is formed through the outer surface 307 and the inner surface 305 at a position of the card slot 301 close to the bottom end 34. The positions of the two card slots 301 correspond to the positions of the two buckles 26, and the hook 260 can be latched in the latching hole 309, so that the card slot 301 and the buckle 26 cooperate to fix the pressing part 20 and the touch part 30.

[0045] The slot 303 extends through from the top end 32 to the bottom end 34. The touch part 30 further includes two oppositely arranged and parallel light-blocking plates 38, and the light-blocking plates 38 are connected to the slot 303 and extend towards the inner surface 305 of the touch part 30. The height of the light-blocking plate 38 is the same as the height of the peripheral wall 36.

[0046] When the pressing part 20 is assembled to the touch part 30, the light guide part 24 is located between the two light-blocking plates 38, and the light guide part 24 is spaced apart from the light-blocking plates 38. If the first side surface 242 of the light guide part 24 is not coated with the black light-blocking layer 226, a reflective layer can also be provided on the surface of the light-blocking plate 38 facing the light guide part 24, so that the light beam emitted by the light guide part 24 is reflected into the light guide part 24 again when it reaches the light-blocking plate 38.

[0047] In this embodiment, when the pressing part 20 and the touch part 30 are assembled together, the length of the light guide part 24 can make it located below the bottom end 34 of the touch part 30. Thus, it is to increase the area of the light incident surface 240, so that the large-angle light beam emitted by the light source 14 can also enter from the light incident surface 240, improving the utilization rate of light.

[0048] The housing 40 includes a cover plate 41 and a receiving cylinder 42 connected to the cover plate 41. The cover plate 41 is provided with an opening 44, and the opening 44 is connected to the receiving cylinder 42. The pressing part 20 and the touch part 30 are assembled into the receiving cylinder 42 from the opening 44.

[0049] In summary, the power button device 100 provided by the present invention includes a switch 10, a pressing part 20, and a touch part 30 fixed to the pressing part 20. Compared with the integrally formed structure in the prior art, in the present invention, the pressing part 20 and the touch part 30 are formed separately and then assembled together. Thus, a material with a high light transmittance can be selected to form the pressing part 20, and a light-transmitting or non-light-transmitting material can be used to form the touch part 30.

[0050] Secondly, the switch 10 includes a receiving groove 12, a light source 14 is provided in the receiving groove 12. The pressing part 20 includes a pressing panel 22 and a light guide part 24 vertically connected to the bottom surface 220 of the pressing panel 22. The light guide part 24 is disposed opposite to the center of the light source 14. The light guide part 24 includes an incident light surface 240, and the incident light surface 240 is an inclined surface that extends obliquely from the bottom surface 220 towards the edge of the pressing panel 22. Since the incident light surface 240 is an inclined surface, the distance between the inclined incident light surface 240 and the light source 14 changes continuously gradually. Thus, the light entering the incident light surface 240 has different optical paths, and the effect of light homogenization can be achieved.

[0051] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed by the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights. In addition, it is obvious that the word "comprising" does not exclude other units or steps, and the singular does not exclude the plural. The multiple devices stated in the device claims can also be implemented by the same device or system through software or hardware. The words such as "first" and "second" are used to indicate names and do not indicate any specific order.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
