Abstract
The utility model discloses a key-press structure, which comprises a first key cap, a second key cap, a base plate and a first extension portion, wherein the first extension portion is extended from the second key cap to the right lower portion of the first key cap, and is connected on the base plate in a rotation way.
Description
Technical field
The utility model relates to a kind of press-key structure with extension, so that it can reach whole slimming design.
Background technology
Now in the daily life, computer institute role is handled audio-visual, electronic game, video signal of today etc. from the simple document in past, function is more and more diversified, and shoulder the keyboard of control interface important task, but do not influence its critical role because of the difference of computer task, by the different key on the keyboard, bring into play every function of its representative, allow the computer user just can control all by the transmission of keyboard.
Fig. 1 shows existing press-key structure.Existing press-key structure 10 comprises a keycap 101, two strutting pieces 102, an elastomer 103 and a substrate 104.Each element division is as follows:
Strutting piece 102 supports keycap 101, and elastomer 103 is positioned at the below of keycap 101, and by substrate 104 supported parts 102 and elastomer 103.
In addition, strutting piece 102 is arranged between cap key 101 and the substrate 104, and articulates with cap key 101 and substrate 104 simultaneously, makes cap key 101 to move up and down with respect to substrate 103.
The combination of existing press-key structure 10 is that strutting piece 102 directly is articulated between keycap 101 and the substrate 104, makes cap key 101 keep moving up and down of level with respect to substrate 103.Yet as a complete unit, existing press-key structure 10 must be kept certain thickness design, just allowed strutting piece 102 between keycap 101 and substrate 104, to carry out moving up and down of level, this restrictive condition then seriously cause press-key structure 10 slowly can't slimming design, and the assembling of its integral body and procedure also can't be further improved.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of press-key structure, to address the above problem.
The purpose of this utility model is achieved in that promptly provides a kind of press-key structure, and it comprises one first keycap, one second keycap, a substrate and one first extension.First extension is extended under first keycap by second keycap, and is connected on the substrate in rotatable mode.
Wherein, more comprise an elastomer, be positioned at first keycap below, and the base plate supports elastomer.
Wherein, first extending part is in elastomeric side.
Wherein, more comprise one second extension, extend under first keycap, and be connected on the substrate, and elastomer is between first extension and second extension in rotatable mode by second keycap.
Wherein, second extension can be a flexible material.
Wherein, second extension is identical with shape, the size of first extension.
Wherein, first extension has one first section and one second section, and first section is connected in keycap, and second section is connected in substrate.
Wherein, second section with substrate press from both sides an acute angle.
Wherein, second section can be a L type.
Advantage of the present utility model is, it can be by the corner dimension between extension and substrate, adjust designed integral thickness, reaching the demand of slimming, and when keycap moves up and down, the problem that does not also have unbalance stress produces, and for making and processing, two shapes and size are identical, and can take the made extension of one-body molded mode, not only can make the production simplification, more can promote its manufacture craft efficient and reduce processing cost and time.
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, preferred embodiment cited below particularly also cooperates appended accompanying drawing to elaborate.

Embodiment
Fig. 2 shows a wherein embodiment of the utility model press-key structure, general press-key structure is made up of a plurality of keycap usually, the press-key structure 20 of present embodiment then only captures first keycap 202 and second keycap 201 wherein, as the schematic diagram of the utility model press-key structure, so that describe.Please consult Fig. 2, Fig. 3 and Fig. 4 simultaneously, press-key structure 20 of the present utility model comprises first keycap 202, second keycap 201, elastomer 203, substrate 204, first extension 205 and second extension 206.Each element division is as follows:
Elastomer 203 is positioned at first keycap, 202 belows, and substrate 204 supports this elastomer 203.
Moreover first extension 205 has one first section 205a and one second section 205b, and wherein first section 205a is connected in 201, the second sections 205b of second keycap and is connected in substrate 204, and second section 205b can be a L type, and with substrate 204 folders one acute angle theta.
In addition, second extension 206 also has identical structure and connection relationship with first extension 205, is then omitted at this, is no longer described.
From the above, press-key structure 20 of the present utility model is with two shapes and the big or small first identical extension 205 and the scissor construction of second extension, 206 replacement prior aries, and it is extended under first keycap 202 by second keycap 201, and be connected on the substrate 204 in rotatable mode, and with substrate 204 folder one acute angle theta so that the second cap key 201 can moving up and down with respect to substrate 204 generation levels.
Therefore, press-key structure 20 of the present utility model can be adjusted designed integral thickness by the corner dimension between extension and substrate, to reach the demand of slimming, and when keycap moved up and down, the problem that does not also have unbalance stress produced, and for making and processing, two shapes and size are identical, and can take the made extension of one-body molded mode, not only can make the production simplification, more can promote its manufacture craft efficient and reduce processing cost and time.
