The plurality of keys 14 are disposed on the base plate 12 for being pressed by a user to perform a function desired to be input by the user. The proposed design of covering the light emitting device with the first shielding sheet of the supporting member can be applied to at least one of the plurality of keys 14, the number of which depends on the practical application of the keyboard 10, the following description is given for the key 14 with the above design on one of them, and the other structural designs of the keys 14 with the same design can be analogized. When the keys of the present invention are applied to a keyboard, the bottom plates of all or part of the keys may be integrated.
As can be seen from fig. 1 and 2, the key 14 includes a key cap 16, a light emitting device 18 and a lifting support device 20, wherein the light emitting device 18 can be combined with the base plate 12 and the light emitting device 18 is located below the key cap 16, in more detail, in this embodiment, the light emitting device 18 can include a thin film circuit board 22 and a light emitting unit 24 (such as a light emitting diode, but not limited to, a light emitting diode), the thin film circuit board 22 is attached to the base plate 12, and the light emitting unit 24 is disposed on the thin film circuit board 22, so that the key 14 can perform light emission control of the light emitting unit 24 through the thin film circuit board 22, for example, control the light emitting unit 24 to emit blinking light or colored lights of different colors.
For a detailed description of the lifting support device 20, please refer to fig. 1, 2 and 3, fig. 3 is an enlarged perspective view of the first support member 26 of fig. 2 from another perspective, as shown in fig. 1, 2 and 3, the lifting support device 20 is disposed between the base plate 12 and the keycap 16, and the lifting support device 20 includes a first support member 26 and a second support member 28, wherein the first support member 26 and the second support member 28 are pivotally connected to each other in a crossing manner and are respectively movably connected to the keycap 16 and the base plate 12, such that the keycap 16 can move up and down relative to the base plate 12 via the lifting support device 20. In more detail, in the embodiment, as shown in fig. 3, the first supporting member 26 extends to the light emitting unit 24 to form a first shielding plate 30 to cover the light emitting unit 24, and the first shielding plate 30 has a first light outlet 32 corresponding to the position of the light emitting unit 24, so that the light emitted by the light emitting unit 24 can be emitted to the keycap 16 through the first light outlet 32, and the key 14 can generate a light emitting effect.

In addition, the design that the first shielding plate 30 extends above the light emitting unit 24 is adopted to replace the design that the L-shaped abdication groove is cut on the supporting member in the prior art, so the invention can strengthen the overall structural strength of the supporting member of the lifting supporting device and improve the problem of poor pressing action of the key cap in the prior art, thereby effectively improving the pressing hand feeling and structural uniformity of the key.
It should be noted that, as shown in fig. 2 and 3, in this embodiment, the first shielding plate 30 may extend to a position where the first supporting member 26 is connected to the base plate 12 to form a bearing bottom edge 34, so that when the key cap 16 moves up and down relative to the base plate 12 via the lifting supporting device 20, the bearing bottom edge 34 may abut against the base plate 12 to provide enough pivoting supporting force to the lifting supporting device 20, thereby further improving the pressing feel of the key 14. In addition, in order to reliably avoid the light leakage problem, as can be seen from fig. 2 and 3, the first shielding plate 30 extends downward from the first light outlet 32 toward the light emitting unit 24 to form at least one retaining wall 36 (three retaining walls 36 are shown in fig. 3 to be formed along the periphery of the first light outlet 32, but not limited thereto), and the retaining wall 36 can shield the light emitted laterally from the light emitting unit 24, so as to generate a lateral light blocking effect.
In practical applications, as shown in fig. 1, the key 14 may further include a light-transmitting sheet 38, and the light-transmitting sheet 38 may be coupled to the first light-emitting opening 32 to generate a protection effect or an effect of changing a light-emitting color. For example, the light-transmitting sheet 38 may be a generally transparent cover sheet to create the effect of covering and protecting the light-emitting unit 24; alternatively, the transparent sheet 38 may be a colored transparent sheet (e.g. a red transparent sheet, a red filter, etc.) that allows the specific color light to pass through, so that the key 14 can emit the specific color light. In addition, the key 14 may further include an elastic structure body 40, and the elastic structure body 40 (such as a rubber washer) may be disposed in the first support member 26 and the second support member 28, so that when the external force pressing the key cap 16 is released, the elastic structure body 40 may provide a return elastic force to the key cap 16 to drive the key cap 16 to return to the non-pressed position, thereby generating an automatic return effect.
In an embodiment, the light emitting device may include a first light emitting unit and a second light emitting unit, the first shielding plate 30 covers the first light emitting unit, the second supporting member 28 extends to the light emitting device 24 to form a second shielding plate to cover the second light emitting unit, the second shielding plate has a second light outlet corresponding to the position of the second light emitting unit, the light emitted by the first light emitting unit is emitted to the first position of the keycap 16 through the first light outlet 32, and the light emitted by the second light emitting unit is emitted to the second position of the keycap 16 through the second light outlet. In actual operation, the light emitted by the first light emitting unit and the second light emitting unit may be different. Alternatively, a second light transmitting sheet 38 is bonded to the second light outlet, and the second light transmitting sheet may be a colored light transmitting sheet that allows the first color light to pass therethrough, and the first color light and the second color light may be different from each other.
It should be noted that the configuration of the light emitting device is not limited to the above embodiment, and the present invention may also be configured by a light emitting unit and a flexible circuit board (Flexible Printed Circuit, FPC), for example, refer to fig. 4, which is a schematic partial cross-sectional view of a keyboard 100 according to another embodiment of the present invention, where the components of the embodiment have the same numbers as those of the above embodiment, and the components have the same structures or functions. As shown in fig. 4, the keyboard 100 includes a bottom plate 12 and a plurality of keys 102 (only one key 102 is shown in fig. 4), the keys 102 include a keycap 16, a lifting support device 20 and a light emitting device 104, in this embodiment, the light emitting device 104 may include a light emitting unit 24 (such as a light emitting diode, but not limited to) and a flexible circuit board 106, the flexible circuit board 106 is attached under the bottom plate 12, an opening 108 is formed at a position of the bottom plate 12 corresponding to the light emitting unit 24, the light emitting unit 24 is disposed on the flexible circuit board 106, and the light emitting unit 24 is disposed in the opening 108 in a penetrating manner, so that the keys 102 perform light emitting control of the light emitting unit 24 through the flexible circuit board 106, for example, control the light emitting unit 24 to emit flashing light or colored lights of different colors.
