Description
Technical field
The present invention relates to a kind of Computer key structure, be specifically related to the press-key structure of notebook computer touch pad.
Background technology
Along with the high speed development of science and technology with information, people more and more be unable to do without computer and network, and the update of computer product is very fast.As the most general computer product of utilization, except that inherent upgrading and personalized design, the consideration of hommization is also fully represented.The effect of computor-keyboard is exactly to system's input instruction, finishes various work, and for the people who often is engaged in words input work, the feel of computor-keyboard is most important, and notebook computer is had higher requirement to button.
Keyboard can be divided into mechanical type, condenser type, Plastic Diaphragm Type Servomotor and conductive rubber formula according to different operation principles.Wherein therefore the button architecture design of Plastic Diaphragm Type Servomotor keyboard also becomes the selected framework of main flow keyboard product on the market gradually owing to have advantages such as cost is lower, the life-span is moderate, feel is good.Inseparable with the Plastic Diaphragm Type Servomotor keyboard is exactly the design of several keycap frameworks, can reduce volcanic crater framework, T framework and scissor framework substantially.
Wherein the volcanic crater framework is the most general design of adopting in the upper keyboard product of market, and the keycap of volcanic crater framework is directly supported by rubber blanket after inserting the volcanic crater, and the key journey is about about 3.80mm～4.0mm.The advantage of this framework is that cost is low, technology is simple, and has certain water-proof function, but because the strong point of keycap only is the cause of a rubber blanket, therefore keycap rocks easily, requirement is knocked finger and is just dropped on keycap central authorities and could obtain best feel, and long feel of time one can change, and noise also therefore and comparatively obvious.And the design of T type framework and volcanic crater framework are comparatively similar, just added a T shape backing strap (volcanic crater framework keycap adopt design for integral type) between keycap and the rubber blanket, so the design of T type framework can prevent the relevant issues that cause because of button is not in place to a certain extent.The design majority of scissor framework is used for notebook and ultra-thin computor-keyboard, scissor framework is two groups of bar linkage structure bracing frames that adopted similar scissors shape between keycap and the rubber blanket, the key journey is about about 2.50mm～3.0mm, this design then can allow user's finger stressed equably on keycap, and each button all can obtain same feel.
But the keycap of scissors pin formula button, all around the fixed form of four parts is different fully, the fixedly buckle of this four-way is not only dismantled difficulty, in the time of installation also painstakingly.And at bigger button, as it is then stable not as little key to make scissor framework, holds the assurance of key journey and feel is very difficult, and then very high to the requirement of framework, has increased the process technology difficulty.
Characteristics such as the automaticity height when IMR (In-mold Rolling, in-mold transfer printing) technology is produced because of it, the cost of production in enormous quantities is lower, product design is versatile and flexible are extensively applied to the button of computer and mobile phone.IMR technology is fit to different materials, and has fine anti-scratch, durability characteristics, can satisfy daily use, and can be as common easy not the fading of spraying paint, or is easy to generate severe marking.In addition, adopt traditional plastic cement to make button and easily produce current mark, spue line, melt run, demoulding albefaction, the shrink phenomenon is arranged, and shortcoming such as look spare is wayward, and aberration is big.
The utility model content
The purpose of this utility model aims to provide a kind of left and right press key structure of notebook computer touch pad, and this press-key structure has diverse outward appearance, and the press-key structure balance and stability is better, button can not rock, rotate, comfortable feel, and it is less to interspace in advance around the button, saves usage space.
For achieving the above object, the utility model is taked following technical scheme:
A kind of press-key structure of notebook computer touch pad, this device comprises, two structural slabs, two keycaps, two connecting rods, a metallic plate, a keyboard conductive film, an intermediate plate, two cushion rubbers, it is characterized in that its structure is: keycap and structural slab carry out the hot melt welding, pack into the draw-in groove of intermediate plate of the button that group is good, connecting rod snaps in the trip of structural slab, intermediate plate be pressed on the keyboard conductive film and with the iron plate hot melt, cushion rubber is placed in the circular hole of intermediate plate, and the computor-keyboard film is attached on the iron plate.
The structural slab both sides respectively are provided with a crooked pull bar, and the bending of pull bar tail end is vertically " Z shape ", and are provided with reference column and peak shape kick, and the peak shape kick is positioned at inside and outside both sides, this Tiebar structure with button be fixed on base iron plate on, prevent that button from sliding.
About keycap and structural slab comprise respectively two, and supporting separately, keycap is provided with little reference column, and structural slab is provided with corresponding little location hole, and keycap can overlap by hot melt with structural slab.
The middle of structural slab also respectively is provided with one and is the circular projection of palisade, this projection is corresponding with the circular hole of intermediate plate, and form with cushion rubber, keyboard conductive film and to dock, structural slab is provided with " ten " font, square, indentation reference column and trip, the trunk portion of bent connecting rod is stuck in the trip respectively, the crotch end then is stuck in the movable draw-in groove of intermediate plate, intermediate plate also is provided with and structural slab reference column and corresponding draw-in groove of connecting rod and location hole, also be provided with little reference column, the keyboard conductive film is provided with the corresponding perforation of reference column with intermediate plate, structural slab.
In addition, keycap adopts IMR technology to be made, and the material of making keycap is * * * (a non-traditional plastic cement).
Advantage of the present invention: can be made into diverse outward appearance, the press-key structure balance, good stability, button can not rock, rotate, comfortable feel, and it is less to interspace in advance around the button, saves the usage space of notebook computer.In addition, this button adopts separate type press-key structure, can can't volume production because of labyrinth, can increase production efficiency, and reduce cost.This structure is particularly useful for the left and right press key of notebook computer touch pad.
Below by drawings and Examples the technical solution of the utility model is described in further detail.
