Background technology
Be used in the Trackpad of mobile computer as the control screen cursor, because of having contact of detecting finger and the function that moves, and be used as cursor control, to drive moving of screen cursor, possessing has volume little, the advantage that area is little, so become the basic outfit of mobile computer, and this Trackpad roughly can be divided into condenser type or resistance-type, its principle of work is to utilize X, the variation that the capacitance of Y-axis or resistance value are produced when contacting because of finger, through obtaining the center and the displacement thereof of finger contact area after the coordinate calculation, and transfer displacement the displacement of screen cursor to, with this moving as the control cursor.
Though have the convenience of moving cursor quickly by Trackpad, but when cursor moves in the screen on certain feature button (icon), when choosing or activating this feature button, then also need to be used the button outside Trackpad, because finger will be controlled cursor on the one hand, watch button again attentively, just can finish pushing of button, still have locating of inconvenience in the operation; The driver of some Trackpad in addition, provide the user utilize finger fast and continuity point by Trackpad, to substitute extra button, though can improve the convenience of use, its convenience still clicks on the project not as moving on to certain at cursor, directly presses down conveniently; Moreover be that cursor control has the left button function different with right button, clicks the function that can only substitute left button continuously and fast, still can't replace the function of right button, still has disappearance in the use in the system as the operation of Windows.
Summary of the invention
In view of this, the objective of the invention is is providing a kind of Trackpad with press pressure detection, it comprises a Trackpad at least, one piezoelectric ceramic plate and a voltage detection circuit, utilize this Trackpad detecting to obtain finger contact and mobile signal, and size by the finger presses power, formed voltage difference changes after seeing through this piezoelectric ceramic plate pressurized, after the judgement via the microprocessor in this voltage detection circuit, to confirm operator's push action, reach by this that controlling cursor moves and, be the effect that the present invention reaches as the input control of keypress function button.
The Trackpad with press pressure detection of the invention described above, it can distinguish function as left button and right button according to the pressure of pushing, and for example dubbing is left button, and weight is right button.
The voltage detection circuit of the invention described above more comprises a voltage oscillating circuit again, uses the vibrations that drive this piezoelectric ceramic plate, with pushing of response user.
Trackpad of the invention described above and piezoelectric ceramic plate are to stick together mutually with scolding tin again.
Again the invention described above voltage detection circuit, be size, to confirm user's push action according to forward voltage that piezoelectric ceramic plate produces.
The voltage detection circuit of the invention described above is when leaving this Trackpad with the detecting finger, to confirm the end of push action again.
When the voltage detection circuit of the invention described above again, the reverse voltage of its this piezoelectric ceramic plate that detects, to confirm the end of actuation of keys.

Embodiment
Fig. 1 is a three-dimensional exploded view of the present invention, Fig. 2 is another three-dimensional exploded view of depression angle of the present invention, wherein the invention provides a kind of Trackpad with press pressure detection, it includes a Trackpad 2, a piezoelectric ceramic plate 3 and a voltage detection circuit 4 at least, wherein:
This Trackpad 2, it is the function that has the touch of detecting finger sensing and differentiate its coordinate position, the electrode that utilization is arranged combines the capacitance variations that is produced with the static between human body, form an induced current and detect its coordinate position, and the end face 21 of this Trackpad 2 is to be an induction zone, the installing on road 221 of can powering of its bottom surface 22, and be provided with more than one first contact 222;
This piezoelectric ceramic plate 3, it is the below that fits in this Trackpad 2, it is that top by a basic unit 31 is provided with an electroplated conductive layer 32, and its underpart is provided with a metal base 33 and forms (seeing also Fig. 3), this electroplated conductive layer 32 is provided with more than one and the second corresponding contact 321 of this Trackpad 2 first contacts 222, and sticks together mutually with scolding tin;
This voltage detection circuit 4 is the voltage (as shown in Figure 3) that produces behind these piezoelectric ceramic plate 3 pressurizeds in order to detect, and it is to comprise:
One analog-digital converter 41 converts digital signal in order to the voltage (simulation) that this piezoelectric ceramic plate 3 is exported;
One microprocessor 42 is digital signals of accepting these analog-digital converter 41 outputs, and judges the variation of its digital signal.
The Trackpad with press pressure detection of the invention described above; it more can be located in the frame shell 1; this frame shell 1 includes a loam cake 11 and a base 12; provide it to support by this base 12 with fixing; and this loam cake 11 to be putamina bodies be overlying on these Trackpad 2 end faces 21, with protection and prevent that it is by directly scratch or wearing and tearing person.
The piezoelectric ceramic plate 3 of the invention described above again, its basic unit 31 is a ceramic material, as barium titanate (BATI03), lead titanates materials such as (PZT) is made.
The piezoelectric ceramic plate 3 of the invention described above again, its metal base 33 is to be a conductive metal sheet, as copper sheet etc.
The piezoelectric ceramic plate 3 of the invention described above when it is subjected to the pressure of finger presses, can produce the distortion of trace again, and exports the first voltage V1 of a forward; And remove (pressure disappearance) when the pressure of finger presses, and this piezoelectric ceramic plate 3 can be replied original shape, and can produce reverse second a voltage V2 (shown in the 4th figure) this moment.
Moreover, voltage detection circuit 4 of the present invention, it more includes a voltage oscillating circuit 43, it is the variation during greater than one first ratings S1 (or one second ratings S2) that receives the first voltage V1 (or second voltage V2) output at this microprocessor 42, promptly export a voltage that exchanges and give this piezoelectric ceramic plate 3, shake with the distortion that makes this piezoelectric ceramic plate 3 be back and forth, and experience slight vibrations, to respond the affirmation that it is pushed for user's finger.
By the composition of the invention described above, the user pushes the relevant start flow process following (seeing also shown in Fig. 3,5) of this Trackpad:
Step 5 detecting second voltage, whether voltage detection circuit 4 detecting piezoelectric ceramic plates 3 have the variation of second voltage V2 output, during less than the second ratings S2, then carry out steps 7 as the obtained second voltage V2 of voltage detection circuit 4; Otherwise then execution in step 6;
Whether step 6 finger leaves, and whether Trackpad 3 detecting fingers leave, in this way execution in step 7 then; Otherwise then execution in step 1;
Step 7 is pushed signal and is stopped, and the signal that voltage detection circuit 4 output one push action stops to be given main frame P, stops to confirm as the action that finger pushes button.
In sum, the present invention can effectively solve the disappearance of habit formula Trackpad, but except that the fast moving screen cursor, but and intuition obtain the function that button is pushed in the mode of pushing, do the option input effector of keypress function button to make things convenient for the user.
