Description
Technical field
The present invention refers to a kind of easy assembling especially, reduces cost and noiseless press-key structure relevant for a kind of press-key structure.
Background technology
Epoch of popularizing of computer now, not only progress and the pursuit on the computer usefulness, its periphery is equipped with as mouse, convenience and aesthetic property on aids such as keyboard use, also more and more paid attention to by the user thereupon, and along with the development of information industry, no matter be work or personal use at present, desktop computer and notebook computer have been popularized in general masses' the life, because computer is widely used in various steady news occasions, as information transportation, commercial intercourse, client's communication, document processing and computer graphics etc., therefore computer has some idea of for the importance of daily life, and so one of of paramount importance input unit is exactly a keyboard in computer equipment.
Seeing also Fig. 1 and Fig. 2, is exploded perspective view and the cross sectional side view that shows known press-key structure respectively.One first balancing pole 1 and one second balancing pole 2 are located at respectively between a base 3 and the keycap 4.Wherein, first balancing pole 1 has a first end 5 and first articulated section 6, and the first end 5 of base 3 relative first balancing poles 1 is provided with a recess 7, and first articulated section 6 of keycap 4 relative first balancing poles 1 is provided with at least one trip 8.The first end 5 of first balancing pole 1 is contained in the recess 7 of base 3, and first articulated section 6 of first balancing pole 1 is snapped in the trip 8 of keycap 4.
Second balancing pole 2 has a second end 9 and second articulated section 10, and the second end 9 of base 3 relative second balancing poles 2 is provided with a hole 11, and second articulated section 10 of keycap 4 relative second balancing poles 2 is provided with a snapping portion 12.The second end 9 of second balancing pole 2 is inserted in the hole 11 of base 3, and second articulated section 10 of second balancing pole 2 is buckled in the snapping portion 12 of keycap 4.
Further set up a flexible member 13 between base 3 and keycap 4, by first balancing pole 1, second balancing pole 2 and flexible member 13, keycap 4 base 3 is relatively done elevating movement.Yet, in known technology, because the position configuration of first balancing pole 1 and one second balancing pole 2 relation, the user is when pushing keycap 4 and make keycap 4 do elevating movement, the collision and produce noise mutually of first balancing pole 1 and the first pad portion 14, and second balancing pole 2 and the second pad portion 15 also can collide mutually and produce noise problem.The second end 9 because of second balancing pole 2 needs labor intensive to operate and be inserted in accurately in the hole 11 of base 3 again, thus there is assembling problem consuming time to derive, and then cause cost to increase.(flexible member 13 diameters are littler to add the diameter of flexible member 13, its elastic tactility is poorer) limited the width (shown in double-head arrow symbol a) of second balancing pole 2, so reducing of this balancing pole 2 width a is very limited, Just because of this, make the volume microminiaturization of the balancing pole 1 of winning, second balancing pole 2, base 3 and keycap 4 more limited.So known keyboard still has disappearance and haves much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of press-key structure, this keyboard structure is more easy on assembling operation, can effectively reduce the manufacturing cost of keyboard, and strutting piece is raw material with plastics again, and adopts the mode of die sinking to make, and also can reduce manufacturing cost.And the user can't be taken place as in the known technology when pushing press-key structure of the present invention, the collision of strutting piece, balancing pole and other part and produce noise problem.
The object of the present invention is achieved like this, a kind of press-key structure, and this press-key structure comprises:
One base;
One keycap is located on this base;
One strutting piece is located between this base and this keycap, and this strutting piece has one first articulated section and one second articulated section, and this first articulated section is articulated in this base, and this second articulated section is articulated in this keycap;
One balancing pole is located between this base and this keycap, and this balancing pole has an end and one the 3rd articulated section, and this end is accommodated in this base, and the 3rd articulated section is articulated in this keycap;
One flexible member is located between this base and this keycap;
Wherein, by this strutting piece, this balancing pole and this flexible member, make relative this base of this keycap do elevating movement.
Preferably, this base first articulated section of this strutting piece relatively is provided with one first holding part, in order to articulate first articulated section of this strutting piece.
Preferably, this keycap second articulated section of this strutting piece relatively is provided with one second holding part, in order to articulate second articulated section of this strutting piece.
Preferably, this base end of this balancing pole relatively is provided with a recess, in order to take in the end of this balancing pole.
Preferably, this keycap the 3rd articulated section of this balancing pole relatively is provided with a trip, in order to articulate the 3rd articulated section of this balancing pole.
Preferably, this base is provided with one first hole, in order to ccontaining this flexible member.
Preferably, this strutting piece is provided with one second hole, makes this flexible member pass second hole of this strutting piece and is connected in this keycap.
Preferably, this keycap this flexible member relatively is provided with a projection, and this flexible member is contacted with this projection.
Preferably, this flexible member further comprises an annulus portion, and the annulus portion of relative this flexible member of this strutting piece is provided with a recess, makes this recess accommodate this annulus portion.
From the above mentioned, press-key structure of the present invention, because first articulated section of strutting piece is articulated in base, and second articulated section of strutting piece is articulated in keycap; And the end of balancing pole is accommodated in base, and the 3rd articulated section of balancing pole is articulated in keycap.By strutting piece, balancing pole and flexible member, keycap base is relatively done elevating movement.And the design of strutting piece and balancing pole or the configuration simplification that becomes makes keyboard more easy on assembling operation, so can effectively reduce the manufacturing cost of keyboard, and strutting piece is raw material with plastics again, and adopts the mode of die sinking to make, and also can reduce manufacturing cost.And the user can't be taken place as in the known technology when pushing press-key structure of the present invention, the collision of strutting piece, balancing pole and other part and produce noise problem.
