Description
Technical field
The utility model relates to a kind of keyboard mechanical structure of keyboard of notebook computer, particularly relates to a kind of keyboard mechanical structure that is applicable to the multiple key (long key) that uses the metal balance bar.
Background technology
Along with Information technology progress with rapid changepl. never-ending changes and improvements, automation equipment enters into each company and family gradually, the chance that people contact with finger-impu system is increasing, and none is not to utilize keyboard and machine to link up such as computing machine, cashing machine etc., and and then carries out its instruction.Because keyboard become the very frequent article of contact in the daily life, so people are also more and more high for its requirements, and no matter its aesthetic appearance, the sense of touch when pushing, motion and sound, balance etc. all require its intimate perfection.
Known bridge formation formula (scissor) button, the keyboard mechanical structure that has been widely used at present keyboard of notebook computer, and general multiple button (as two times of keys, three times of isometric keys of key), because the longer dimension of its keycap, the operator not necessarily forces in the keycap center just when pushing keycap, therefore cause the phenomenon that keycap tilts when pushing easily, and then cause and definitely to import, even can cause the damage of keyswitch because of misoperation.For making the multiple key can balance play, generally can be between the keycap of button and base plate installing one rubber-like metal balance bar, the setting by balance stem can make the application of force that presses on keycap be passed to the keycap center, so that keycap can move stably.
See also Fig. 1, Fig. 2 and Fig. 3, keyboard mechanical structure for a kind of known keyboard of notebook computer, it is by a keycap 10a, one first support 11a, one second support 12a, an one base plate 13a and a balance stem 14a constitute, described first support 11a and the cross-shaped setting of the second support 12a, and with the pivot 15a of this first support 11a and this second support 12a lower end, 16a is articulated in described base plate 13a and goes up corresponding pivot seat 17a, among the 18a, the upper end of the described first support 11a and the second support 12a then is connected in the bottom surface of described keycap 10a, forms a bridge formation structure by described two support 11a and 12a.
Has a projection 19a on the first support 11a of this bridge formation structure, this projection 19a is positioned at the middle lower end of the described first support 11a, the lug 20a that has a correspondence on described base plate 13a, when described keycap 10a is pressing down in the process, described projection 19a can conflict lug 20a and locate.
Described balance stem 14a one is the metallic rod body of " U " type, body of rod 21a is articulated in the bottom surface of described keycap 10a in the middle of it, its two side levers body 22a then is arranged in described base plate 13a and goes up in the circular hole 24a of corresponding conduit assembly 23a, this circular hole 24a is level to running through, and be higher than the end face of base plate 13a, setting by balance stem 14a can make the application of force that presses on keycap 10a be passed to keycap 10a center, thereby makes keycap 10a can move up and down (as Fig. 2 and Fig. 3) stably.
In addition, can insert an elasticity between described keycap 10a and the base plate 13a and touch body 25a, this elasticity shake-up body 25a is positioned between the stroke of this keycap 10a action.Done by described two support 11a, 12a guiding parallel up and down when mobile as this keycap 10a, and the elasticity of this keycap 10a below is touched body 25a can press or leave FPC 26a, makes keyswitch do ON or OFF action.
But, the keyboard structure of notebook computer is gradually in compact design at present, therefore also reduce gradually the design space of balance stem, and because the space of design when minimizing, can produce fixing hole axle and set meter, for this balance stem 14a can be rotated, reserve bigger contact gap (as Fig. 2 A and Fig. 3 A) between two side lever body 22a that then need and the circular hole 24a of base plate 13a at this balance stem 14a, the origin of sound is mostly because the excessive caused noise of contact gap of the circular hole 24a of the two side lever body 22a of balance stem 14a and base plate 13a at present, and the two side lever body 22a of balance stem 14a and the circular hole 24a contact area of base plate 13a are big, also cause bigger noise easily.
As from the foregoing, above-mentioned known keyboard of notebook computer button obviously has inconvenience and exists with disappearance on reality is used, can wait to be improved.
