For the structure of the mouse touch pad, the touch pad is a capacitive touch pad supporting multi-point touch control, and the user can conduct touch operation simultaneously by using multiple fingers, thus improving the response sensitivity, accuracy and operation convenience of the mouse touch pad, and being beneficial to reducing the thickness of the touch pad.
Description
Technical field
The utility model relates to a kind of computer input equipment, especially a kind of notebook computer slide-mouse touch pad structure by the touch operation transmission signals.
Background technology
Slide-mouse touch pad (touch pad) is the mouse of present the most widely used mobile PC, it is all indispensable input equipment of each notebook computer, the original intention of system manufacturer design is to want to allow the user exempt trouble with external mouse, and realize the dream of mobile office at any time under fully need not the situation of external equipment, to reach the purpose of breaking away from the restriction of standard mouse operating space.Yet for most user, the slide-mouse touch pad is undoubtedly the synonym of chicken ribs, and is not only showy and not substantial, have a false reputation, and uses very arduously, causes work efficiency low, wasted the valuable working time.
Why the slide-mouse touch pad becomes chicken ribs, be that deficiency by its structure is determined, existing slide-mouse touch pad structure sees also shown in Figure 1, this slide-mouse touch pad 20 is located at the below at button interface on the keyboard body 10, mainly have one can the finger sensing running orbit pressure sensitivity plate 21 and two buttons 22,23, this button 22,23 is equivalent to the mechanical mouse left-right key.Please cooperate again referring to shown in Figure 2, the inner structure of this touch pad 20 comprises a rigid plastic substrate 24, these substrate 24 outside surfaces scribble one deck ITO conductive layer 25, be stamped one above and mould layer 26 firmly, this inside surface of moulding layer 26 firmly also scribbles one deck ITO conductive layer 27, be distributed with transparent isolating points 28 between this ITO conductive layer 25,27, this moulds layer 26 firmly can directly be pressure sensitivity plate 21 and button 22,23.When touch operation, ITO conductive layer 25 is pushed and touched to ITO conductive layer 27, and resistance changes and produces signal, through sensor circuit signal is delivered to microprocessor.
Structure by above existing slide-mouse touch pad as can be known, existing slide-mouse touch pad produces signal by resistance variations, this kind structure is called the resistive touch plate.Because the resistive touch plate needs just can make a response after the up and down two-layer ITO conductive layer collision.Therefore, when 2 simultaneously during pressurized, it is uneven that the pressure of slide-mouse touch pad becomes, and can cause touch-control error to occur.Such principle has caused the resistive touch plate can only realize single-point touches, and will a little firmly push and could realize touching effect.During concrete operations, can only lean on moving of a finger to realize moving and clicking of cursor, because reaction is insensitive, often need operation several times could realize purpose, it is very arduous to use.And firmly push for a long time the wearing and tearing that cause the touchpad surface material easily, perhaps two-layer ITO conductive layer follows the string and causes the appearance of loose contact problem up and down, therefore can influence the normal serviceable life of product.
In addition, existing slide-mouse touch pad is a sandwich construction, cause the thickness of whole touch pad to increase, the thickness of whole keyboard is by the thickness decision of thick assembly, and the thickness of existing slide-mouse touch pad in whole keyboard components for the thickest, therefore, finally caused the increase of whole keyboard thickness, not only cause waste of material, more against in the frivolous small and exquisite development trend of electronic product.
The utility model content
The technical problems to be solved in the utility model provides a kind of notebook computer slide-mouse touch pad structural improvement, and it can improve the convenience of the sensitivity, accuracy and the use that touch reaction, shortens the time of operation.
For solving the problems of the technologies described above, notebook computer slide-mouse touch pad structural improvement of the present utility model has a plastic base, and this real estate is the touch operation face to user's one side, and the another side of this substrate forms a conductive layer.
Described conductive layer directly plates the another side of being located at this substrate.
Form electrode pattern on the described conductive layer.
Compare with existing slide-mouse touch pad structure, notebook computer slide-mouse touch pad structural improvement of the present utility model has following advantage and beneficial effect:
1, with the condenser type slide-mouse touch pad of existing single-point touch resistance-type slide-mouse touch pad improvement for the support multi-point touch, can detect produced simultaneously multiple point touching signal, thereby can realize many fingers touch operation simultaneously, and the whole operation face can be used as button and use, so not only improve the convenience of sensitivity, accuracy and the use of touch reaction greatly, and shortened the time of operation.
2, simple in structure, thin thickness helps reducing the thickness of whole keyboard, meets the small and exquisite frivolous development trend of electronic product.The utility model has only double-layer structure, and substrate is a monoblock flat board, need not to establish in addition the button that is equivalent to the mouse right and left key, has so not only increased the area of operating surface, has improved the convenience of user's operation, and because of the processing of being more convenient for simple in structure.
3, very sensitive to the reaction that touches, only need finger to touch and get final product, can not cause the wearing and tearing of operating surface, thereby can prolong the serviceable life of product.

Embodiment
Understand for technology contents of the present utility model, characteristics and effect being had more specifically, existing in conjunction with illustrated embodiment, details are as follows:
See also shown in Figure 3, slide-mouse touch pad 40 of the present utility model is located at the below of these keyboard body 30 key areas, it comprises the substrate 41 of a plastic material, this substrate 41 is a touch operation face 410 in the face of user's one side, the user touches operating surface 410 by finger, can carry out touch operation; Please cooperate and consult shown in Figure 4ly, the another side of this substrate 41 is built with a conductive layer 42, and this conductive layer 42 is one deck ITO conducting film at least, is plated on the another side of this substrate 41 by the mode of plating, sputter or evaporation; Form electrode pattern on this conductive layer 42, to form circuits sense unit 50 (prior aries, concrete structure is not shown in the figures), microprocessor 60 (the prior aries of this circuits sense unit 50 and keyboard 30, concrete structure is not shown in the figures) electrically connect, the transmission circuit unit 70 (prior art, concrete structure not shown in the figures) of these 60 whiles of processor with this keyboard 30 electrically connects.
See also shown in Figure 5, when finger touches the operating surface 410 of slide-mouse touch pad 40, because the existence of people's bulk electric field, form a coupling capacitance between user's finger and the operating surface 410, finger is walked a very little electric current, this electric current flows out the electrode from 40 4 angles of touch pad respectively, and the electric current of four electrodes of flowing through in theory and finger are proportional to four jiaos distance; By circuits sense unit 50 this variation signal is transferred to computer microprocessor 60, computer microprocessor 60 calculates by the precision to four current ratios, draws touch location; This computer microprocessor 60 is transferred to transmission circuit unit 70 with the signal of computing; Transmission circuit unit 70 is transferred to motherboard processing unit 80 (prior aries with signal, so do not give unnecessary details), and be for further processing by motherboard processing unit 80, finally show to carry out touching clickable icon, option program, the amplification that instruction produced by display 90 (prior art is not so give unnecessary details) dwindles the page, different operational orders such as browses.
