A kind of capacitance touch type mouse, the capacitance touch type mouse, comprise mouse body and be installed in the interior pcb board of mouse body, described pcb board is provided with single-chip microcomputer, also comprise touch pad, touch chip and soft-touch control, described touch pad is close to the bottom of the upper casing of mouse body, described touch chip is arranged on the bottom or pcb board of touch pad, described soft-touch control respectively with touch chip and link to each other with single-chip microcomputer on the pcb board, described touch chip is electrically connected with single-chip microcomputer on the pcb board, the front of described mouse body is provided with left key area and right button district, and described left key area and right button district are provided with slider bar respectively, and described slider bar links to each other with the touch chip; Described soft-touch control comprises the button that is arranged on the pcb board and is arranged at the cylinder of bottom of the upper casing of mouse body, described button respectively with touch chip and link to each other with single-chip microcomputer on the pcb board, described cylinder runs through touch pad and is connected on the button.

On the basis of the above, the slider bar on the left key area described in the utility model and right button district equidistantly distributed along vertically being of front of mouse body; The center section in described upper casing front is middle keypad; Described touch pad is close to the bottom of upper casing by double faced adhesive tape or glue; Described touch chip is connected with single-chip microcomputer by universal serial bus; Described touch chip is a condenser type single-point touches chip; Described touch pad is common pcb board or flexible PCB plate.

Compared with prior art, the utlity model has following advantage: the utility model adopts touch pad and a physical button, realized that two fingers slide on a large scale and about in the triple bond function, have 2 fingers arbitrarily to slide on a large scale, flexibly smooth, speed is freely, solved the problem that scroll wheel damages easily, use the single-point touches chip to realize the basic function of multiple point touching simultaneously, reached the effect of quick page turning; Button links to each other with touch chip electricity with single-chip microcomputer simultaneously, has overcome the problem that right and left key fast on time can be malfunctioning that touches; In addition, go up shell integrated elegant in appearancely, and can prevent that the front drips on a small quantity.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

As Fig. 1, shown in Figure 2, capacitance touch type mouse of the present utility model, comprise upper casing 1, lower casing 2 and pcb board 3, described upper casing 1 and lower casing 2 engagings are combined on, described pcb board 3 places in the housing and is fixed on the lower casing 2, described pcb board 3 is provided with single-chip microcomputer 4, also comprise touch pad 5, touch chip 6 and soft-touch control, described touch pad 5 is close to the bottom of upper casing 1 by double faced adhesive tape or glue 13, described touch chip 6 is arranged on the bottom or pcb board of touch pad 5, described soft-touch control comprises a button 7 that is arranged on the pcb board 3 and the cylinder 8 that is arranged at the bottom of upper casing 1, described button 7 respectively with touch chip 6 and link to each other with single-chip microcomputer 4 electricity on the pcb board 3, described cylinder 8 runs through touch pad 5 and is connected on the button 7, described touch chip 5 is electrically connected with single-chip microcomputer 4 on the pcb board 3, the front of described upper casing 1 is provided with left key area 10, right button district 11 and middle keypad 12, described left key area 10 and right button district 11 are respectively equipped with slider bar, and described slider bar links to each other with the touch chip.Mouse body of the present utility model can be selected wired or wireless mouse according to user's needs, and touch plate material can adopt common PCB or flexible PCB.

As shown in Figure 3, the utility model has been divided some slider bar L1s to Ln along the vertical equidistant of front of mouse body for realizing 2 finger sliding functions in the left key area L of left button touch and forefinger sliding area, as L group slider bar; In the right button district R of right button touch and middle finger sliding area, some slider bar R1 have been divided to Rn along the vertical equidistant of front of mouse body, as R group slider bar, the slider bar of L group and R group all touches chip and is connected, touch the chip timing scan, when pointing when the mouse Petting Area moves, touch and deliver to the page turning data of single-chip microcomputer again after chip calculates the slip side-play amount as roller, make L group and R group slider bar not only can discern finger and whether exist, also can calculate finger draw runner position, place respectively.In order to be fit to people's use habit, keypad M during the front of mouse is provided with between left key area and right button district.
