Description
Technical field：
The utility model belongs to smart mobile phone technical field, is related to the intelligent hand that a kind of rear shell has touchpad operation function
Machine, smart mobile phone one-handed performance is realized, occasion is prepared for mobile phone.
Background technology：
The input equipment of smart mobile phone is touch-screen, also known as " touch screen ", " contact panel ", is that one kind can receive contact
Deng the induction type display device of input signal, when contacting the graphic button on screen, the haptic feedback system on screen can
Various link devices are driven according to the formula of preprogramming, are substituted for mechanical push button panel, and by display picture
Produce lively visual and sound effects, can simply, conveniently, naturally realize man-machine interaction.The key property of touch-screen has at 3 points：
First, transparent, infrared technology touch-screen and surface acoustic wave touch screen are one layer of pure glass, and other touch-screens are the compound of multilayer
Film, weigh its quality and consider at least four aspects：Transparency, color distortion degree, reflective and definition；Second, touch-screen
It is absolute coordinate system, is physically a set of independent coordinate positioning, the data touched every time is turned by calibration data
It is that the elements of a fix and the last elements of a fix are not related each time the characteristics of absolute coordinate system for the coordinate on screen, it is same
The output data of point is stable, and the essential distinction with this kind of Relative positioning systems of mouse is the intuitive for having one-time-reach-place；
3rd, detection is touched and positioned, and various touch screen technologies are all to carry out work by respective sensor, or even the touch-screen having
Inherently a set of sensor, respective positioning principle and sensor each used determine touch-screen reaction speed, can
By property, stability and life-span.
Smart mobile phone screen tends to screen enlarging at present, needs a hand-held mobile phone using operation, another hand operates screen, double
Hand, which coordinates, to be completed, and made troubles to user；And touch pad with its stable performance, it is easy to operate the advantages that and as most
The standard configuration of number notebook computer, its part that can be selected as functions such as cursor navigation, selection or confirmations, touch
Plate generally use capacitance induction principle, some electrodes are designed and produced in the upper surface of pcb board, one layer of plastics are covered in electrode surface
Plate, when the finger or felt pen of people are in stroke on plastic plate, the capacitance on electrode can change, so as to detect
The situation of change of the coordinate value and coordinate value of finger or felt pen on pcb board, this coordinate value is corresponded on display can
To realize the functions such as cursor navigation.General touch pad is divided into resistance-type and electromagnetic type, is needed when resistive touch plate touches to touching
Touch and a little directly press, electromagnetic type touch pad needs to use special time writer.In the prior art, Chinese patent CN201662774U
A kind of input unit of handheld device and a kind of handheld device are disclosed, it is positive that the input unit includes handheld device housing
Control element is a control ball or control-rod, to control the cursor in the display device of handheld device；The device is also included extremely
A few side key, the side key are realized between handheld device and operating personnel by the Software Coding pre-set
Information exchange；It singlehanded can be used, but need to be placed on mobile phone on platform and be operated；Chinese patent CN203243380U is disclosed
A kind of intelligent terminal easy to operation, including a terminal body, set at least the one of the side of the terminal body and the back side
Operator is equipped with, it is provided with the operator of more than three, and is realized by the operator at side and the back side to front operator
One hand manipulation；It singlehanded can be used, but operator is more, and complicated and maintenance and preparation cost are higher；China Patent No.
CN203301578U discloses a kind of mobile phone with assist type touch controller, including is arranged at mobile phone body back or sidepiece
Touch control panel, control panel include the substrate positioned at outer layer, are covered in the sensing unit of substrate back and sensing unit leads to
The touch-control IC for crossing that wire is connected, the touch-control IC are connected with mainboard CPU, can performed by sliding the touch controller
Various programs, it singlehanded can be used, and touch control panel is integrated in mobile phone body, and overall structure is more complicated, is prepared and is tieed up
It is higher to accomplish this；Chinese patent CN204376974U discloses a kind of Intelligent flat mobile phone of band auxiliary touch screen, in mobile phone shell
It is upper to be provided with auxiliary touch screen, pressure sensitive module.By setting, the working condition of auxiliary touch screen may be selected, to main display
The touch-control state of screen replaces main display dispaly state, closed mode.Under touch-control state, the hand that will sense of auxiliary touch screen
Refer to mobile relevant position signal or direction, rate signal feed back to main display by CPU, cursor moves with finger, cursor
When reaching destination locations, press pressure induction module, the pressing signal sensed is sent into CPU, performs command adapted thereto；It can
One hand uses, but frequently uses pressure sensitive module, is easily caused damage of components.
The content of the invention：
The shortcomings that the purpose of this utility model is to overcome prior art to exist, seeking to design a kind of rear shell has touch pad
The smart mobile phone of operating function, solve Mobile phone screen greatly can not one-handed performance or mobile phone must be placed on platform and operate, or operation
