The light-emitting unit is electrically connected to the circuit board; Positioning on the bottom plate corresponding to the light-emitting unit and having a light-emitting hole, the light emitted by the light-emitting unit is emitted outside the light-shielding structure through the light-emitting hole; the key cap is disposed above the bottom plate; the elastic member is not disposed Between the circuit board and the keycap, for providing an elastic force to move the keycap relative to the board. When the keycap is pressed, the elastic member triggers the corresponding switch via the corresponding opening α_. As described above, since the bottom plate of the present invention is disposed on the circuit board, and the light-shielding structure of the present invention can be directly disposed on the bottom plate, the light-shielding structure can be assembled to the circuit board along with the bottom plate during assembly, and the light-shielding structure and There is no problem of assembly interference between the boards, and at the same time, the assembly process is simplified. The advantages and spirit of the creation can be further understood by the following detailed description of the creation and the drawings. [Embodiment] 2 is a schematic view of a keyboard 2 according to an embodiment of the present invention. As shown in FIG. 2, the keyboard 2 includes a bottom plate 30, a circuit board 32, and a plurality of buttons 3 The button 3 is arranged on the bottom plate 30, and the button 3 can be pressed by the user to enter the function of the user to input. 6 M419150. Please refer to Fig. 3, and Fig. 3 is the button 3 ^ χ χ line in Fig. 2 As shown in Fig. 3, the button 3 includes a bottom plate 30, a circuit board 32, a light-emitting unit %, a key cap 36, a lifting support device 38α, and an elastic member 4. The bottom plate 3 is disposed on the circuit board. The light-emitting unit 34 is electrically connected to the circuit board 32. The key cap 36 is disposed above the bottom plate 30, and the lifting support device 38 is disposed between the key cap 36 and the bottom plate 30. In this embodiment, the circuit board 32 can be a thin film circuit. The light-emitting unit 34 can be a Light Emitting Diode (LED). In addition, the elastic member 4 is disposed between the circuit board % and the key cap 36, and the elastic member 40 is used to provide an elastic force to make the key cap. 36 moves up and down relative to the circuit board 32. In an actual application, one end of the elastic member 4 of the present invention abuts against the bottom of the key cap 36, and the other end of the elastic member 40 is selectively attached to one of the circuit board 32 or the bottom plate 30, It depends on actual needs. Further, in this embodiment, the elastic member 4 may be a rubber dome, but not limited thereto. For example, it can also be a metal dome, in other words, as long as it can provide the elastic design of the key cap 36, which is protected by the creation. It is worth mentioning that the circuit board 32 has a switch 321 such as a membrane switch or other trigger switch. Further, an opening 3〇1 is formed at a position corresponding to the switch 321 on the bottom plate 3. When the key cap 36 of the button 3 is pressed, the projection 4〇1 in the elastic member 40 can trigger the switch 321 on the circuit board 32 via the opening 3〇1, thereby performing the function desired by the user. 7 M419150 The step-by-step key cap 36 has a first chute 361 and a first card slot, for example, and has a first chute 3〇3 and a second card slot 3〇5. The elevating branch device further The first branch member 381 is pivoted. The first branch member 381 has a first sliding portion and a first holding portion. In the first support member 381, the first sliding portion is disposed in the first sliding slot 361, and the first pivoting portion 3812 is rotatably engaged in the -card slot 3〇5. The second sliding portion 383 is slidably disposed on the second sliding slot 3 〇 3, and the second pivoting portion is assembled The portion is rotatably dragged into the first card # slot 363. Thereby, when the key cap % of the button 3 is pressed, the key cap % can be moved up and down relative to the bottom plate 30 by the lifting and lowering device 38. As shown in FIG. 3, the button 3 further includes a light-shielding structure, which is disposed on the bottom plate 30 corresponding to the position of the light-emitting unit 34 on the circuit board 32. When the bottom plate 3 is assembled to the circuit board 32 The rear light-shielding structure 42 is formed with a receiving space between the light-shielding structure 42 and the circuit board 32 for accommodating the light-emitting unit W. The light-shielding structure 42 has a light-emitting aperture. The light emitted by the light-emitting unit 34 can be emitted through the light. The hole 423 is emitted from the light-shielding structure 42. Further, the key cap 36 has a light-transmitting portion 365 at the corresponding light-emitting hole 423. Thus, the light-emitting unit 34 is in the light-emitting hole 423 of the light-emitting unit 34. The light-transmitting portion 365 of the key cap 36 is emitted outside the key cap 36 to achieve the function of causing the button 3 to emit light. In this implementation, the light-shielding structure 42 of the present invention can be integrally formed with the bottom plate 3 (8 M419150).
且由於絲30餘胁板32上，故轉上述额3G 32的設置關係’當絲結構42隨底板3()—同轉至電路板u 時，遮光結構42與電路板32之間不會發生組裝干涉的問題。^ 方面，本創作之遮光結構42係連同底板3卜起組裝至電路板7 上，故不需操作人_外朗光結構42進行組裝，因此，可 組裝時因人為因素所產生的誤差。由上述可知，本創作之士播 42之出光孔423可準確地對應至發光單元34的位置上導致:Moreover, since the wire 30 is on the slab 32, the relationship of the above-mentioned 3G 32 is changed. When the wire structure 42 is transferred to the circuit board u with the bottom plate 3 (), the light-shielding structure 42 does not occur between the circuit board 32 and the circuit board 32. The problem of assembly interference. In the aspect, the light-shielding structure 42 of the present invention is assembled to the circuit board 7 together with the bottom plate 3, so that the operator _ the outer light-light structure 42 is not required to be assembled, and therefore, an error due to human factors can be assembled. As can be seen from the above, the light hole 423 of the creation of the creator 42 can accurately correspond to the position of the light-emitting unit 34:

The 夂 key is actually used for the money, and the light-shielding structure 42 can be selectively applied to the wire 3G according to the material of the hybrid 3G by means of stamping into a thin film. For example, when the spring bottom plate is composed of a plastic material, the light-shielding structure 42 can be formed on the surface of the glass by using the injection molding method; when the 3G is in the domain of the gold-like texture, the light-shielding structure is made; the punching can be used (10) The pattern is mixed on the bottom plate 3G. In this way, the lying light-shielding structure 42 and the bottom plate 3G are formed into a design, and the creation can further omit the opening of the mold for the light-shielding structure from the call to the health county, so that the price is more competitive in the market. Advantage. Compared with the prior art, since the bottom plate of the present invention is disposed on the circuit board, and the shading junction J of the present invention is disposed on the bottom plate, the shading structure can be assembled to the circuit board together with the bottom plate, and the shading is shielded. There is no problem of assembly interference between the structure and the board' and at the same time the assembly process is simplified. In addition, since the calendering structure can be integrally formed with the bottom plate by stamping or injection molding according to the material of the 9 M419150 bottom plate, the mold opening can be omitted, thereby reducing the production cost of the keyboard and making the keyboard price on the market. More competitive advantage. In addition, since the light-shielding structure can be selectively connected to the bottom plate body, the operator does not need to additionally install the light-shielding structure, so that the error caused by the human factors can be avoided step by step. The light-emitting hole of the light-shielding structure of the present invention can accurately correspond to the position of the light-emitting unit, so that the light can be tidy from the JL to the hair; 'By this, the creation can improve the light-emitting effect of the button and the keyboard. The above is only the preferred embodiment of the present invention, and all changes and modifications made by the scope of the patent application should be covered by this creation.
