A kind of structure of computor-keyboard
Technical field
The utility model relates to a kind of computer field, is specifically related to a kind of structure of computor-keyboard.
Background technology
The structure of existing computor-keyboard comprises five big assembly materials basically, and aluminium sheet is used to do the substrate of bottom support; Flexible circuit board, the electronic devices and components of realization keyboard entry function; Silica gel push-button, make keyboard can production capacity move up and down and obtain feel assembly; The scissors pin is used to realize the assembly that moves up and down and connect; Keycap, the keyboard appearance part, and, realize that the user obtains the assembly of visual information at its surface printing literal.
Aluminium sheet mainly adopts sheet material aluminium sheet or corrosion resistant plate through the multiple working procedure drawing; Flexible circuit board mainly is to adopt silk-screen printing technique on the polyester film material, forms electronic circuit, after drawing, and is connected to computer main board electron gain signal; Silica gel push-button is the silica gel material of certain degree of hardness, adopts ejection formation or hot-forming, obtains certain shape by mould; The scissors pin, the main material in polyester resin that adopt obtain by ejection formation more; Keycap mainly is to adopt material in polyester resin, obtains by ejection formation.
It mainly is to connect keycap and aluminium sheet by the scissors pin that the assembly of keyboard connects, and flexible circuit board and silica gel push-button be clipped between aluminium sheet and the keycap, in supporting role by silica gel push-button, realize that keycap can stand on the aluminium sheet, the user is when pressing keycap, by the rotation of scissors pin, realize pressing down, realize resilience by silica gel push-button when unclamping.
Summary of the invention
The purpose of this utility model provides a kind of structure of computor-keyboard, pass through structural design, realize the repertoire of existing keyboard, and can obtain keyboard and reach the noiseless effect and the function of integral waterproofing in the process of knocking, embody the function of quiet keyboard and can guarantee that keyboard can operate as normal at special environment condition.
The technical solution adopted in the utility model is: a kind of structure of computor-keyboard, comprise keycap, flexible circuit board and substrate, described keycap engages with substrate by the silica gel pillar, described flexible circuit board is sealed between keycap and the substrate, flexible circuit board is the single-layer type structure, described keycap is divided into three parts, the key cap surface layer is the high rigidity silicon gel part, the keycap main body is middle hardness silicon gel part, the keycap bottom is conduction carbon granules part, is provided with the both positive and negative polarity that circuit touches part with conduction carbon granules part correspondence position on the described flexible circuit board.
As preferably, described substrate adopts plastic plate, aluminium sheet, iron plate, corrosion resistant plate.
As preferably, described baseplate material adopts flexible material, becomes software keyboard.
As preferably, the top section of described keycap is provided with fluorescent material, becomes luminous keyboard.
The utility model can obtain needed profile of keyboard and internal structure by drawing or injection molding respectively, flexible circuitry adopts the single-layer type design, the circuit envelope is except that contact point, adopt the insulative water-proof material to be coated with, keycap partly adopts repeatedly forming technique of silica gel, utilize the silica gel material of different hardness, reach key cap surface height hardness, the characteristic of hardness in the bottom, and the silica gel pillar by the keycap back side is realized the function that is connected with substrate, utilize the sealing property of silica gel, realization is airtight fully with substrate, guarantee the water resistance of keyboard, because of wiring board adopt for single-layer type designs, so can consider keyboard start process the airtight problem that may cause.
Beneficial effect: the utility model utilizes repeatedly forming technique of silica gel, the silica gel material of different hardness is attached to one becomes a kind of novel key cap, realizes two kinds of functions of original keycap and button, and the closed nature of binding silica gel material, with closely cooperating of substrate, realize the seal of keyboard.The utility model can reduce a large amount of shape technologies of dashing on original keyboard Designing, reduce intrinsic operation, and can very simply realize the assembly of keyboard towards shape mould and jetting mold and correspondence, make and reduce great amount of manpower, to obtain the least cost of keyboard in the production process of keyboard.
