Abstract

The utility model relates to a capacitance type mouse comprising a capacitance type touch pad, a shell and a USB interface, wherein the touch pad is in the shell; and the mouse also comprises an operating handle which extends outwards through the touch pad. When using the capacitance type mouse, a user only grips the mouse and can equally operate/control the change of a cursor as well through the operating handle, even when the mouse is separated from a desktop, thus realizing that the operation is similar to a game player, so that a user can use the mouse more conveniently and fast.

Description

Capacitive mouse

Technical field

The utility model relates to a kind of mouse, refers in particular to a kind of capacitive mouse.

Background technology

Along with computer technology rapid development, mouse has also become a kind of input equipment indispensable in the computer peripheral, common in the market have an optical mouse, its principle of work is: establish a light emitting diode in optical mouse inside, by the light that this light emitting diode sends, illuminate the optical mouse lower surface; With a part of light of optical mouse lower surface reflected back,, be transferred to the interior imaging of a photoinduction device (little imager) then through one group of optical lens.Like this, when optical mouse moved, its motion track just can be registered as the coherent image of one group of high-speed capture.Utilize a special image analysis chip (DSP of optical mouse inside at last, be digital microprocessor) a series of images that absorbs on the motion track is carried out analyzing and processing, by the variation of characteristic point position on these images is analyzed, judge mouse moving direction and displacement, thereby finish the location of cursor.

Though optical mouse operates very convenient, also there are a lot of shortcomings, as very sensitive to light, if use optical mouse, a little less than then indoor light is wanted relatively, otherwise cursor positioning is inaccurate; Moreover the carrier strong to reflective located also inaccurate; Also have a kind of situation be exactly the user in use, if it is parked in the air, just can not continue to use, the principle of work of optical mouse has determined to have a supporting body, and it is impossible that the mode of operation that wants to realize the similar operations game machine is come operated optronic mouse.In order to operate mouse more flexibly, we can select for use the mouse of other type to solve above problem.

Therefore need solve above problem for users provide a kind of convenient mouse.

Summary of the invention

The actual technical matters to be solved of the utility model is how a kind of user's handled easily that supplies is provided, and need not rely on the capacitive mouse of any supporting body.

In order to realize above-mentioned purpose of the present utility model, the utility model provides a kind of capacitive mouse, and it comprises capacitive type touch pad, shell and USB interface, and wherein touch pad is positioned at shell, this mouse also comprises an operating grip, and this operating grip stretches out by touch pad.

Capacitive mouse described in the utility model, the user in use, even mouse leaves supporting body such as desktop, the user equally holds MouseAcross and crosses the variation that handle just can be operated the control cursor, realization is similar to the same operation of game machine, so the user is convenient, quick when using this mouse.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Please shown in Figure 1 in conjunction with consulting, capacitive mouse 1 described in the utility model mainly comprises capacitive type touch pad 10, operating grip 11, shell 12 and USB interface (not indicating).Wherein, operating grip 11 is positioned at the inside of shell 12, and stretches out by touch pad 10.

Described capacitive type touch pad 10 is positioned at the front side of whole mouse 1, please refer to shown in Figure 2ly, and this capacitive touch control plate 10 comprises sense film 101, substrate 102 and circuit board 103.Wherein said sense film 101 is fixed on the described substrate 102, and sense film 101 is used for responding to the variation of its surface capacitance, and described circuit board 103 is positioned at the below of described substrate 102.

Described operating grip 11 stretches out from described touch pad 10, and the user can be directly operate this handle 11 with finger, thus joystick the centre push and the upper and lower, left and right four direction on rock.Because the utility model is to extend handle 11 on capacitive touch control plate 10, so handle 11 needs to adopt the condenser type conductor material.In the time of could guaranteeing the user by finger manipulation handle 11 like this, can cause changes in capacitance on the described Trackpad 10, thereby detect its movement locus.Its principle of work is as follows: when user's finger on the sense film 101 on capacitance touch control board 10 surfaces during operating grip 11, can cause the variation of capacitance touch control board 10 surface capacitances, this variation is by described capacitance touch control board 10 detectings, and convert current signal or voltage signal to, at this moment, described capacitance touch control board 10 just can be measured corresponding operation trace signal on X and the Y plane through signal Processing, by signal amplifying apparatus it is noted then, be that the A/D change-over circuit converts corresponding signal and data to through digital to analog converter again, be transferred to processor, last processor is finally judged direction and distance that this handle 11 moves by processing and analysis to data on described capacitive touch control plate 10.

Described touch pad 10 is owing to be positioned at the front side of whole mouse 1, so a finger that only needs the user just can operating grip 11, so more convenient to use.Shell 12 still is arranged to arch, to satisfy the operating gesture of user's custom.During use, USB interface is inserted on the corresponding host computer, can manipulates.

In order to adapt to user's use habit, described handle 11 when left and right directions rocks, may be defined as mouse 1 about click; Rocking of above-below direction may be defined as the front and back page turning; Middle click may be defined as definite; What handle while all directions were not stopped rocks, and promptly may be defined as the location of cursor.

Capacitive mouse described in the utility model, the user in use, even mouse leaves desktop, the user only holds the same variation that can operate the control cursor by handle of mouse, realization is similar to the same operation of game machine, thus the user using, convenient, quick.
