With reference to the partial schematic diagram of pressing direction, an embodiment edge D1 section of luminous button of the present invention open shown in Fig. 3.See Fig. 3, luminous button 001 comprises: keycap 1, upper cover 2, waterproof membrane 3, circuit board 4, distance piece 5 and light source 6; Wherein, light source 6 can be light-emitting diode (light-emittingdiode, LED) device, such as, but not as limit, light source 6 also can be other light-emitting devices, Cold Cathode Fluorescent fluorescent tube (coldcathodefluorescentlamp, CCFL).
Keycap 1 has press section 11, guide pillar 12, first space S 1 and perforate 111; Press section 11 has first surface 112, and first surface 112 adjoins waterproof membrane 3, and perforate 111 is opened in the fringe region of press section 11, and perforate 111 is communicated with this first space S 1 and runs through first surface 112; Guide pillar 12 has first end 121 and the second end 122, the first end 121 of guide pillar 12 connects press section 11, the contiguous light source 6 of second end 122 of guide pillar 12, guide pillar 12 and press section 11 define the first space S 1, first space S 1 is arranged along pressing direction D1, and this first space S 1 is just to the light L that light source 6 sends to receive light source 6; Keycap 1 can be made up of dark material or lighttight material, to ensure that light L only propagates with perforate 111 from this first space S 1, and can not enter propagation in the material layer of keycap 1 and cause fall apart or light leak accumulateing of light L.
Upper cover 2 has button hole 21, the 4th surface 22, encloses portion 23 and lower surface 24, upper cover 2 is located in keycap 1, button hole 21 is corresponding with keycap 1, that is, enclose portion 23 along pressing direction D1 offering button hole 21 to abdicate keycap 1 along the position that is pressed on pressing direction D1, keycap 1 runs through button hole 21 and can move around on pressing direction D1, exposes upper cover 2 so that user's pressing to make press section 11.
Waterproof membrane 3 has second surface 31 and the 3rd surface 32, waterproof membrane 3 is attached at the 4th surface 22 of upper cover 2 by waterproof gum layer 9 and covers keycap 1, namely, the second surface 31 of waterproof membrane 3 is attached at the 4th surface 22 of upper cover 2 by waterproof gum layer 9, and second surface 31 covers button hole 21, second surface 31 is attached at the first surface 112 of press section 11.Whereby, can prevent liquid from entering button 001 from upper lid surface and affecting the structures such as circuit board 4, avoid the damage of electronic devices and components, improve fail safe.In the present embodiment, waterproof membrane 8 is made up of light transmissive material.
Circuit board 4 is provided with light source 6 and trigger member 7, light source 6 is just to this first space S 1 that guide pillar 12 position of keycap 1 is formed; Trigger member 7 is just to the second end 122 of guide pillar 12, and when keycap 1 moves along this pressing direction D1 to circuit board 4, the second end 122 of guide pillar 12 can contact trigger member 7 to realize the conducting of button 001.
Distance piece 5 is the column structure of hollow, and distance piece 5 is arranged between upper cover 2 and circuit board 4 to form accommodation space S2; Distance piece 5 has the first edge 52 and the second edge 53, see Fig. 4, the first edge 52 adjoins with the lower surface 24 of upper cover 2, and the second edge 53 is connected to the surface of circuit board 4, whereby, upper cover 2, distance piece 5 and circuit board 4 form airtight this accommodation space S2.Keycap 1, light source 6, trigger member 7 are all positioned at this accommodation space S2.In the present embodiment, distance piece 5 is one-body molded with keycap 1, and forms elastic arm 8 between keycap 1 and distance piece 5, that is, keycap 1, elastic arm 8 and distance piece 5 are formed in one design, and structure is simpler, it is more convenient to process, simultaneously, actuation of keys is smooth and easy, and can not produce firmly stagnant, feel is better; Keycap 1, elastic arm 8 and distance piece 5 can by dark material or lighttight material be one-body molded makes, to ensure that light L only propagates from this first space S 1 with perforate 111, and can not enter in the material layer of keycap 1, elastic arm 8 or distance piece 5 and propagate, light L is caused to accumulate loose or light leak, allow light L not scatter, and promote the intensity appearing the light L of button 001.In the present embodiment, when first edge 52 adjoins with the lower surface 24 of upper cover 2, the portion that encloses 23 of upper cover 2 extends towards the press section 11 of keycap 1 and protrudes from distance piece 5 part, so, when pressing keys 001, also there is certain elastic space, strengthen feel further.
So, on pressing direction D1, be respectively arranged with waterproof membrane 8, upper cover 2, keycap 1, light source 6 and circuit board 4, wherein, keycap 1 runs through button hole 21 from this accommodation space S2 and attaches to make first surface 112 and second surface 31.Waterproof membrane 8 is attached by the portion that encloses 23 of waterproof gum layer 9 with upper cover 2, to cover keycap 1, light source 6 and trigger member 7 in this accommodation space S2, ensure that the light L that light source 6 is launched in this accommodation space S2 only can propagate on the path of this first space S 1, perforate 111, then be incident upon in external environment condition through waterproof membrane 8.
Refer to the partial structurtes schematic diagram of the open embodiment of the present invention one keyboard components of Fig. 4, in this figure, upper cover 2 and keycap 1 are not arranged on it.See Fig. 4, keyboard components 002 has the luminous button 001 of multiple above-described embodiment, distance piece 5 has spaced walls 51, adjacent two luminous buttons 001 share a spaced walls 51, so, keyboard components 002 meets luminance raising when realizing printing opacity, improve pressing feel while, be conducive to the isolation of each light source, effectively ensure that the light that the light source of each luminous button is launched too does not scatter and mutually disturbs.
The present invention is described by above-mentioned related embodiment, but above-described embodiment is only enforcement example of the present invention.Must it is noted that the embodiment disclosed limit the scope of the invention.On the contrary, change done without departing from the spirit and scope of the present invention and retouching, all belong to scope of patent protection of the present invention.
