Abstract
The utility model relates to a key structure of a keyboard, which comprises a base plate, a film circuit board mounted on the base plate, an elastic body mounted on the film circuit board, a scissor mounted on the base plate and a key cap mounted on the scissor. In the key structure of the keyboard, the elastic body is directly arranged on the film circuit board, so as to avoid the complex process and structure that in a conventional keyboard, an elastic body is arranged on a film circuit board through a polyester film, so as to effectively reduce the cost of the keyboard while maintaining the service performances of the keyboard. Besides, the key structure of the keyboard simplifies the assembly process and increases the production efficiency.
Description
Technical field
The utility model relates to keyboard structure, and particularly a kind of cost is lower, assembles keyboard press button structure more easily.
Background technology
Keyboard is extensively applied to the input of computer and various electronic product equipment as a kind of common input unit.Along with being extensive use of of electronic product, keyboard occupies very consequence as man-machine communication's means in whole system.The structure of the existing keyboard that uses generally is made up of keycap, scissors pin, elastomer, polyester film (or PET film), film circuit board, aluminium sheet and base etc., when keycap is applied pressing force, keycap presses downwards in elastomer, make elastomer pass through polyester film and the conflict film circuit board, thereby the formation circuit turn-on is realized keyboard operation.As United States Patent (USP) the 6th, 020, No. 566, the 6th, 428,223B2 number, the 6th, 545,232B1 number; Chinese patent application No. 97115426.0 " key switch " has disclosed scissors foot keyboard structure respectively.Yet, the keyboard structure of existing this kind structure is just towards miniaturization and slimming development, the keycap area of button also makes the button internal structure be tending towards complicated thereupon dwindling relatively, required level is more, cause assembling procedure comparatively loaded down with trivial details, and materials used is many, is unfavorable for the reduction of cost, the raising of production efficiency, and is not easy to maintenance.
The utility model content
The purpose of this utility model is to provide a kind of keyboard press button structure, and it directly is installed on elastomer on the film circuit board, reduces the use of polyester film, is beneficial to reduce cost, enhance productivity and convenient for maintaining.
For achieving the above object, the utility model keyboard press button structure comprises: substrate, be installed on film circuit board on the substrate, be installed on elastomer on the film circuit board, be installed on the scissors pin on the substrate and be installed on keycap on the scissors pin.
The beneficial effects of the utility model: the utility model keyboard press button structure, it is that elastomer is directly installed on the film circuit board, and avoided elastomer in the existing keyboard to be installed in complicated process and structure on the film circuit board by polyester film etc., thereby when guaranteeing the keyboard serviceability, can effectively reduce its cost, and simplified assembling process, enhance productivity, and make it be convenient to maintenance more.
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effect apparent by embodiment of the present utility model is described in detail.
In the accompanying drawing,
Figure 1A to 1B is the three-dimensional exploded view of the utility model keyboard press button structure;
Fig. 2 is the section of structure of the utility model keyboard press button structure.
Embodiment
For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
Shown in Figure 1A, 1B, the utility model keyboard press button structure, it comprises: a substrate 2, a film circuit board 4, an elastomer 6, a scissors pin 8 and a keycap 10.
In the present embodiment, form an a pair of conduit and the independent carrier of accommodating on substrate 2 surfaces, described carrier equates with the distance that described a pair of each of accommodating in the conduit is accommodated conduit.Film circuit board 4 can be made a response with respect to the deformation state of elastomer 6, realizes the disconnection or the UNICOM of circuit, thereby produces corresponding signal.Elastomer 6 can produce distortion according to moving up and down of keycap 10.This scissors pin 8 comprises outer support arm 81, reaches and the hinged interior support arm 82 of outer support arm, its one-tenth X type bracing frame capable of being combined, and be contained in respectively between substrate 2 and the keycap 10, thereby play the integrated support effect in that button is inner, and can moving up and down and slide with keycap 10.Keycap 10 has plane, top and baseplane, forms a pair of isolated first carrier and a pair of isolated second carrier on the described baseplane so that the scissors pin to be installed.
As shown in Figure 2, scissors pin 8 is installed between keycap 10 and the substrate 2 by carrier, and elastomer 6 is installed on the film circuit board 4, and film circuit board 4 is installed on the substrate 2, and substrate 2 places the bottommost of button.Described substrate 2 is an aluminium sheet 2, and described film circuit board 4 is installed on the aluminium sheet 2, and keycap 10 is located at the top of this film circuit board 4, and elastomer 6 and scissors pin 8 correspondences are located between keycap 10 and the film circuit board 4.Described scissors pin 8 upper ends are installed on the carrier of keycap 10 belows, its lower end is installed on the carrier of aluminium sheet 2 by film circuit board 4, keycap 10 is supported in the top of film circuit board 4 by this scissors pin 8, elastomer 6 place in keycap 10 belows scissors pin 8 in the middle of the thread vacancy.Especially, described elastomer 6 is directly installed on the film circuit board 4 by viscose glue stickup or other fixed forms etc., has reduced the use of polyester film or PET film etc. in the prior art like this, reduces cost and enhances productivity thereby be beneficial to.This elastomer 6 is made and be can be multiple shape by rubber, in this specific embodiment, elastomer 6 is half-circle-arc shape for the section lower end.
In the utility model, when keycap 10 is applied pressing force, the scissors pin 8 of keycap 10 belows slides and descends, keycap 10 descends thereupon, elastomer 6 stressed flexural deformations simultaneously and conflicting downwards to film circuit board 4, keycap 10 touches film circuit boards 4 and turning circuit by this elastomer 6, and produces one and push signal, 4 of film circuit boards can transmit this signal to processor carrying out signal processing, thereby realize the input of keyboard.
In sum, the utility model keyboard press button structure, it is that elastomer is directly installed on the film circuit board, and avoided elastomer in the existing keyboard to be installed in complicated process and structure on the film circuit board by polyester film etc., thereby when guaranteeing the keyboard serviceability, can effectively reduce its cost, and simplified assembling process, enhanced productivity, and made it be convenient to maintenance more.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model claim.
