Embodiment

See also Fig. 1, Fig. 1 is the schematic diagram according to the keyboard 1 of the utility model first embodiment.As shown in Figure 1, keyboard 1 comprises base plate 3, sliding part 5 and a plurality of button 7.Sliding part 5 is mounted slidably in base plate 3 times.Button 7 is arranged on the base plate 3, pushes for the user, and then carries out the function of user institute desire input.

See also Fig. 2, Fig. 2 be among Fig. 1 button 7 along the profile of X-X line.As shown in Figure 2, button 7 comprises base plate 3, sliding part 5, keycap 70, first magnetic part 71, second magnetic part 72, elastic component 73 and liftable supporter 74.Liftable supporter 74 is arranged between keycap 70 and the base plate 3.Keycap 70 has first chute 700 and first draw-in groove 702.Base plate 3 has second chute 30 and second draw-in groove 32.Liftable supporter 74 comprises first strutting piece 740 and second strutting piece 742, and wherein second strutting piece 742 and first strutting piece 740 articulate.First strutting piece 740 has first sliding part 7400 and first articulated section 7402.When assembling first strutting piece 740, first sliding part 7400 is mounted slidably in first chute 700, and first articulated section 7402 is articulated in second draw-in groove 32 rotationally.Second strutting piece 742 has second sliding part 7420 and second articulated section 7422.When assembling second strutting piece 742, second sliding part 7420 is mounted slidably in second chute 30, and second articulated section 7422 is articulated in first draw-in groove 702 rotationally.By this, keycap 70 can follow liftable supporter 74 to move vertically towards the direction of base plate 3.

Elastic component 73 is arranged between keycap 70 and the base plate 3.In practical application, button 70 can comprise the circuit board (not shown) in addition, is arranged on the base plate 3.Have the switch corresponding on the circuit board, for example thin film switch (membrane switch) or other triggering property switch with button 70.Elastic component 73 can be rubber washer (rubber dome), but not as limit.Elastic force required when elastic component 73 promptly moves up and down as keycap 70 relative base plates 3 is originated.When button 7 is pressed, the switch on the elastic component 73 meeting circuits for triggering plates, and then carry out the function that user institute desire is imported.

Keycap 70 has bottom surface 704, the first magnetic parts 71 and is arranged at bottom surface 704, and second magnetic part 72 is arranged on the sliding part 5.In this embodiment, first magnetic part 71 is different towards the polarity of a side of keycap 70 towards the polarity and second magnetic part 72 of a side of base plate 3.For example, first magnetic part 71 can be the N utmost point towards the polarity of a side of base plate 3, and second magnetic part 72 can be the S utmost point towards the polarity of a side of keycap 70, as shown in Figure 2.In other words, if first magnetic part 71 is the S utmost point towards the polarity of a side of base plate 3, then second magnetic part 72 is the N utmost point towards the polarity of a side of keycap 70.

See also Fig. 3, Fig. 3 is in the schematic diagram of collapse state for keycap 70 among Fig. 2.As shown in Figure 3, when second magnetic part 72 moves to first magnetic part, 71 belows along with sliding part 5, because first magnetic part 71 is different towards the polarity of a side of keycap 70 towards the polarity and second magnetic part 72 of a side of base plate 3, so attract each other between first magnetic part 71 and second magnetic part 72 and produce attraction.In this embodiment, this attraction needs the elastic force that produced because of compression greater than elastic component 73, so that keycap 70 moves towards the direction of base plate 3.By this, keycap 70 promptly is in collapse state, to reduce keyboard 1 whole height.In practical application, can the operating portion (not shown) that be available for users to operate be set on sliding part 5, when the user spurs this operating portion, can drive sliding part, and then fold each button 7 on the keyboard 1.In addition, also the button (not shown) can be set on keyboard 1, and see through suitable circuit and mechanism design, when allowing the user push this button, promptly drive sliding part automatically.

In addition, when second magnetic part 72 moved apart first magnetic part, 71 belows along with sliding part 5, the attraction between first magnetic part 71 and second magnetic part 72 disappeared, at this moment, the elastic force that elastic component 73 is produced because of compression makes keycap 70 move towards the direction away from base plate 3, as shown in Figure 2.By this, keycap 70 reverts to user mode, is available for users to push, and then carries out the function of user institute desire input.

See also Fig. 4, Fig. 4 be according to the button 7 of the utility model second embodiment ' profile.Button 7 ' be keycap 70 ' have first protuberance 706 with the main difference part of aforesaid button 7, and base plate 3 has second protuberance 34, wherein second protuberance 34 is close to first protuberances 706, and second protuberance 34 is overlapped at the direction and first protuberance 706 of vertical base plate 3.In this embodiment, when keycap 70 ' when being pressed, first protuberance 706 moves towards the direction of parallel base plate 3 each other with 34 restrictions of second protuberance, makes keycap 70 ' can move vertically towards the direction of base plate 3.It should be noted that, the assembly of same numeral among Fig. 4 and Fig. 2, its action principle is roughly the same, does not repeat them here.

See also Fig. 5, Fig. 5 is the button 7 according to the utility model the 3rd embodiment " profile.Button 7 " is button 7 with the main difference part of aforesaid button 7 " and more comprises loam cake 75, and loam cake 75 is arranged on the base plate 3.The both sides of loam cake 75 respectively have guidance part 750, and keycap 70 " both sides respectively have sliding part 708.In this embodiment, can on sliding part 708, form the hole (not shown), guidance part 750 can pass this hole, so that sliding part 708 is mounted slidably on guidance part 750.By this, " when being pressed, keycap 70 " can move vertically towards the direction of base plate 3 when keycap 70.It should be noted that, the assembly of same numeral among Fig. 5 and Fig. 2, its action principle is roughly the same, does not repeat them here.

Compared to prior art, the utility model utilizes magnetic part to produce attraction, keycap is moved towards the base plate direction, so button can fold downwards.In addition, button of the present utility model and keyboard can be applicable to mobile computer, when the user is entire when going up the screen of mobile computer, because button can fold, therefore can avoid screen and button to produce colliding and impaired.Moreover, after folding, button can reduce the mobile computer whole height, and make mobile computer be easier to slimming.

According to the detailed description of above embodiment, hope can be known description feature of the present utility model and spirit more, and is not to come the utility model is limited with above-mentioned disclosed embodiment.
