Thus, the contact area of the surface of the pressing part can be increased. By the small area contact between the slide part and a base inner wall, the operation of the computer keyboard is convenient and a biased phenomenon can be dropped.
Description
Technical field
The utility model relates to a kind of keycap of computer keyboard, relates in particular to a kind of loam cake pedestal that is arranged on computer keyboard, can increase the press section surface contact area, and light along the keycap structure that makes things convenient for and can reduce the bias voltage phenomenon when pressing operation.
Background technology
Because computer is widely used in various information occasions, in information transportation, commercial intercourse, client's contact, document processing, computer graphics and various work, so computer is for the importance of the daily life particular importance that also just seems.Input equipment the most important and next to the shin in computer equipment is operated by the keycap of pushing keyboard then no more than keyboard (Keyboard), and program command or data are imported in the main frame rapidly in time.Because it is the most frequent that this keycap contact with the user, the operation of therefore providing convenience, feel be good, assemble the easy low keycap of cost that reaches, and becomes those skilled in the art's research topic.
The keycap of known computer keyboard can probably be divided into the integrally formed keycap that is used for personal computer and the composite type keycap that is used for notebook (is commonly called as: the two big classifications scissors pin).Though wherein the keycap used of personal computer has assembling and is easy to characteristic, but because the thickness of its press section is quite thick, and its surface is little with the contact area of user's finger, feel when causing operating letter symbol not good and that be located at the surface, press section can not obtain to amplify, and more can't obtain to reduce on cost of material; And the keycap that notebook is used is made up of keycap and bridge formation mechanism, its complicated integral structure, and suitable loaded down with trivial details difficulty and expending time in aspect assembling makes cost of manufacture can't effectively obtain to reduce.
So, the design people is in view of the defective that exists in the above-mentioned prior art, rely on the sector experience for many years of being engaged in, at carrying out improved defective, through concentrating on studies and cooperating actual utilization, in line with excelsior spirit, propose a kind of reasonable in design and effectively improve the utility model of above-mentioned defective finally.
The utility model content
Main purpose of the present utility model is to provide a kind of keycap of computer keyboard, it utilizes the minimizing of the thickness of press section, can increase the press section surface contact area, and utilize sliding part to contact, make operation more light along convenient and can reduce the bias voltage phenomenon with small size between base internal wall.
To achieve these goals, the utility model provides a kind of keycap of computer keyboard, and this keycap is arranged on the loam cake pedestal of computer keyboard.This keycap comprises press section and the sliding part that extends outward from this press section; This sliding part has and compresses assembly and be arranged on the coupling assembling that this compresses the assembly outside; This coupling assembling is centered on by a plurality of side plate to form, and is respectively equipped with trip on one group of corresponding side plate therein, in addition, is formed with the inclined plane respectively in the joint of any two-phase adjacent side plate, is provided with vertical raised line on this inclined plane.
Keycap with the utility model computer keyboard of said structure, because the thickness of its press section is little, and its surface is big with the contact area of user's finger, can amplify so the good hand touch during operation is located at the letter symbol on surface, press section simultaneously, and can reduce cost of material; And, utilize sliding part to contact with small size between base internal wall, make operation more light along convenient and can reduce the bias voltage phenomenon.
