Description
Technical field
This novel computer key technical field that relates to relates in particular to the shaftless framework of a kind of employings and is fit to the mechanical automation assembling, and the minimizing keycap rocks, scissor computer key cheaply.
Background technology
Along with the development of information industry, the increasingly extensive use of computer, no matter be that notebook or desktop computer all be unable to do without computer key, yet traditional scissor foot keyboard press-key structure complexity is not suitable for current mechanization production assembling, as Figure of description 1.The shortcoming of this class formation is as follows: one: cost is high, and not only the Mold Making cost is high for the conventional scissors leg structure, and the injection moulding production cost is also high, quality is difficult to control, consume a large amount of man-made assemblies, labour cost is higher, and production efficiency is low is the problem of present this industry headache.Its two: structure is insecure, and keycap easily rocks.Following scissor foot keyboard is super book type structure, need like this structure of scissor very accurate, the rotating shaft diameter only has 0.5-0.7mm, the edge diameter generally only has 1-1.2mm thick, add that the rough traditional structure of this class has affected his support strength, easily produce rocking of keycap when cutting the support oscilaltion inside and outside making, its three: this class formation can not make the supporting surface of scissor support and button cap and button base plate maximize, do not rock injustice when finger can produce by at the keycap mid point time, affect the comfort of feel.Its four: need to open notch above or below axis hole during the assembling of conventional scissors pin inside casing and housing, so no doubt facilitated installation, but reduced the intensity after the assembling, when keyboard is clashed into because of carelessness or falls in situation, inside casing and housing easily from groove day mouth come off, such structure is firm not.its five: traditional scissor leg structure complexity is irregular, the man-made assembly difficulty, production efficiency is low can't realize the machine automatization operation, one of reason: traditional scissor leg structure docking point many scissors inside casing and frame structure are too complicated, the frame of interior housing all will be provided with respectively four overhanging axiss of a cylinder outward, and also need to be respectively equipped with four docking points on keycap bottom surface and button base plate, a button, need to fill eight groups of docking points, 101 buttons of a keyboard need fill 808 docking points, so many docking point man-made assembly efficient is low, cost is high, be not easy to large-scale production.Former therefore two: these a large amount of quasi-tradition scissors are deposited in a time-out, and because outer frame body and interior housing have respectively jack-post and frame hole, mutually intersecting mixed is one, artificial explanation difficulty, and more None-identified ranking of machinery can't realize the machine automatization equalization.Therefore, in view of the above-mentioned problems with the shortcoming inventor with the sector design experiences for many years, propose a kind ofly new can promote quality and can be convenient to the machine automatization equalization again, the simplification structure of low-cost high efficiency through repetition test repeatedly.
Summary of the invention
This novel purpose is exactly that the shaftless framework of a kind of employings that provides for the deficiencies in the prior art part is fit to the mechanical automation assembling, and the minimizing keycap rocks, scissor computer key cheaply.
for achieving the above object, this novel technical scheme is: a kind of computer key without the card base scissor, include: button cap, scissor, the flexible silicon colloid, button base plate and cover printed circuit book film on the button base plate, the top of flexible silicon colloid is passed and is withstood on behind scissor frame hole on the button cap bottom surface, the bottom of flexible silicon colloid is positioned on the key switch of printed circuit film, described scissor is comprised of outer frame body and internal frame body two parts, internal frame body and outer frame body are to be combined into one by axle and hole docking, the whole gap of internal frame body is assemblied in outer frame body inside and makes internal frame body to rotate freely in outer frame body,
Described internal frame body is the framework of a symmetric figure, and internal frame body is to interconnect by inside casing forearm, inside casing postbrachium, inside casing left arm, inside casing right arm the rectangle framework that forms;
Described outer frame body is the framework of a symmetric figure, and this outer frame body is to interconnect by housing forearm, housing postbrachium, housing left arm, housing right arm the rectangle framework that forms, the cylinder that housing forearm and housing postbrachium all connect for ease of rotating shaft;
The bottom surface of described button cap is provided with the interior cucurbit groove deck of two keycaps and keycap side snap fit of distribution triangular in shape, after assembling, in two keycaps, cucurbit groove deck is rotationally connected respectively with after the clamping of outer frame body forearm, and keycap side snap fit slides with the internal frame body postbrachium and docks; Be provided with cucurbit groove deck and base plate side snap fit in two base plates of distribution triangular in shape on the button base plate, after assembling, in two base plates cucurbit groove deck be rotationally connected after the outer frame body postbrachium engages, base plate side snap fit docks with the slip of internal frame body forearm; Base plate side snap fit opening on keycap side snap fit on described button cap bottom surface and described button base plate distributes dorsad.
Described internal frame body and outer frame body are to be combined into one by axle and hole docking, concrete structure is: left arm and centre position, the right arm outside at internal frame body have a center of circle axis hole, and this center of circle axis hole be up and down entity structure, left arm and centre position, right arm inboard at outer frame body are respectively equipped with one to projecting inward cylinder axis, after combination, outer frame body is inserted into by cylinder axis and realizes the axis hole docking in center of circle axis hole corresponding on internal frame body.
Described internal frame body and outer frame body are to be by the concrete structure that axle and hole docking are combined into one: left arm and centre position, right arm inboard at outer frame body have a center of circle axis hole, and this center of circle axis hole be up and down entity structure, left arm and centre position, the right arm outside at internal frame body are respectively equipped with an outwardly cylinder axis, after combination, internal frame body is inserted into by cylinder axis and realizes the axis hole docking in center of circle axis hole corresponding on outer frame body.
Described internal frame body and outer frame body are the injection mo(u)lding thing, and described inside casing forearm and inside casing postbrachium are cylinder.
Described button cap and two interior cucurbit groove decks of keycap and a keycap side snap fit are integrated injection molding part.
