Embodiment
See also Fig. 2, Fig. 2 is the sketch map according to the keyboard 2 of the utility model one embodiment.As shown in Figure 2, keyboard 2 comprises base plate 30, circuit board 32 and a plurality of button 3.Each button 3 is arranged on the base plate 30, and button 3 is available for users to push, and then carries out the function of user institute desire input.
See also Fig. 3, Fig. 3 is that button 3 among Fig. 2 is along the profile of X-X line.As shown in Figure 3, button 3 comprises base plate 30, circuit board 32, luminescence unit 34, keycap 36, liftable supporter 38 and elastic component 40.Base plate 30 is arranged on the circuit board 32, and luminescence unit 34 is electrically connected at circuit board 32.Keycap 36 is arranged at base plate 30 tops, and liftable supporter 38 is arranged between keycap 36 and the base plate 30.In this embodiment, circuit board 32 can be film circuit board, luminescence unit 34 can be light-emitting diode (Light Emitting Diode, LED).In addition, elastic component 40 is arranged between circuit board 32 and the keycap 36, and elastic component 40 is used to provide elastic force so that keycap 36 relative circuit boards 32 move up and down.In practical application, an end of the elastic component 40 of the utility model is connected to the bottom of keycap 36, and the other end of elastic component 40 optionally is attached on one of them of circuit board 32 or base plate 30, and it is looked actual demand and decides.In addition, in this embodiment, elastic component 40 can be rubber washer (rubber dome), but not as limit.For instance, it also can be dome reed (metal dome), in other words, so long as the structural design of keycap 36 elastic force can be provided, all belongs to the scope that the utility model is protected.
What deserves to be mentioned is to have switch 321 on the circuit board 32, for example thin film switch (membrane switch) or other triggering property switch.Further, be formed with opening 301 on the position to inductive switch 321 on the base plate 30.When the keycap 36 of button 3 was pressed, the protuberance 401 in the elastic component 40 can be via the switch 321 on the opening 301 circuits for triggering plates 32, and then carried out the function of user institute desire input.
Further, keycap 36 has first chute 361 and first draw-in groove 363, and base plate 30 has second chute 303 and second draw-in groove 305.Liftable supporter 38 further comprises first strutting piece 381 and second strutting piece 383, and wherein second strutting piece 383 and first strutting piece 381 articulate.First strutting piece 381 has first sliding part 3810 and first articulated section 3812.When assembling first strutting piece 381, first sliding part 3810 is mounted slidably in first chute 361, and first articulated section 3812 is articulated in second draw-in groove 305 rotationally.Second strutting piece 383 has second sliding part 3830 and second articulated section 3832.When assembling second strutting piece 383, second sliding part 3830 is mounted slidably in second chute 303, and second articulated section 3832 is articulated in first draw-in groove 363 rotationally.By this, when the keycap 36 of button 3 was pressed, keycap 36 can move up and down with respect to base plate 30 by liftable supporter 38.
As shown in Figure 3, button 3 includes light-shielding structure 42 in addition, and it is arranged on the position of the luminescence unit 34 on the base plate 30 corresponding circuits plates 32.After base plate 30 is assembled on the circuit board 32, be formed with accommodation space 421 between light-shielding structure 42 and the circuit board 32, be used for ccontaining luminescence unit 34.In addition, light-shielding structure 42 has light hole 423.By this, the light launched of luminescence unit 34 can penetrate outside the light-shielding structures 42 via light hole 423.Further, keycap 36 has transmittance section 365 in corresponding light hole 423 places.Thus, the light that luminescence unit 34 is launched can penetrate outside the keycaps 36 via the light hole of light-shielding structure 42 423 and the transmittance section 365 of keycap 36, thereby reaches the effect that makes button 3 luminous.
In this embodiment; The light-shielding structure 42 of the utility model can be one-body molded with base plate 30; And because base plate 30 is arranged on the circuit board 32; So according to the be provided with relation of above-mentioned base plate 30,, can not assemble the problem of interference between light-shielding structure 42 and the circuit board 32 when light-shielding structure 42 together is assembled to 32 last times of circuit board with base plate 30 with circuit board 32.On the other hand, the light-shielding structure 42 of the utility model is assembled on the circuit board 32 together with base plate 30, so do not need that operating personnel are extra to assemble light-shielding structure 42, therefore, can avoid when assembling the error because of human factor produced.From the above, the light hole 423 of the light-shielding structure 42 of the utility model can correspond on the position of luminescence unit 34 exactly, causes light accurately to send from light hole 423 forwards, and by this, the utility model can promote the illumination effect of button 3 and keyboard 2.
In practical application, light-shielding structure 42 can be according to the material of base plate 30 and is optionally utilized punch forming or the mode of ejection formation is formed on the base plate 30.For instance, when base plate 30 was made up of plastic material, the mode of light-shielding structure 42 ejection formations capable of using was formed on the base plate 30; When base plate 30 was made up of metal material, the mode of light-shielding structure 42 punching press raisings capable of using was formed on the base plate 30.Thus, by light-shielding structure 42 and base plate 30 integrated designs, the utility model can omit to the offering of the mould of light-shielding structure further, thereby reduces the production cost of keyboard, makes the keyboard price on market, have more competitive advantage.
In prior art; Because the base plate of the utility model is arranged on the circuit board, and therefore the light-shielding structure of the utility model can directly be arranged on the base plate; When assembling; Light-shielding structure can together be assembled on the circuit board with base plate, and does not have the problem that assembling is interfered between light-shielding structure and the circuit board, and has simplified assembling flow path simultaneously.In addition; Because light-shielding structure can optionally utilize the punch forming or the mode of ejection formation and base plate one-body molded according to the material of base plate; So can omit offering of mould, thereby reduce the production cost of keyboard, make the keyboard price on market, have more competitive advantage.In addition, because light-shielding structure can be optionally one-body molded with base plate, so do not need that operating personnel are extra to assemble light-shielding structure; Therefore; Can avoid further in when assembling because of the error that human factor produced, and then the light hole of the light-shielding structure of the utility model can be corresponded on the position of luminescence unit exactly, cause light accurately to send from the light hole forward; By this, the utility model can promote the illumination effect of button and keyboard.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
