Below hall device induction module, capacitive sensing module are elaborated.
The hall device induction module can comprise 4 sensor units, magnet and resilience mechanism.Wherein, magnet is fixed on the slide plate below, and moves along with moving of slide plate.
The resilience mechanism of hall device induction module comprises holder part and elastic force system, can be made up of materials such as spring, plastic cement, magnet.The main effect of resilience mechanism is when the slide plate of slide plate is not applied to external force, guarantee that slide plate remains static and is positioned at initial point, when slide plate is applied in external force, make slide plate free movement in the scope that resilience mechanism allows, after externally applied forces on the slide plate disappears, guarantee that slide plate returns initial point, and remain static.If the shape of slide plate is not centrosymmetric, then resilience mechanism also needs to increase anti-rotation structure, guarantees that slide plate makes same point be positioned at initial point all the time, can not rotate when all directions move horizontally.
The magnet of hall device induction module is fixed on the slide plate below, can move with slide plate.Under the effect of horizontal external, for example, user's finger push slide plate, slide plate drives magnet and moves together.The magnet area is less than Hall chip, and and Hall chip between certain distance is arranged.It is square in the heart that magnet is positioned at the center of Hall chip, when magnet was static, the magnetic flux of 4 sensors in the Hall chip was identical, when magnet moves, 4 sensors can be sensed the variation of magnetic flux separately, and the embedded computing unit of Hall chip goes out the position of magnet according to the change calculations of magnetic flux.The hall device induction module exports the position of magnet to main control chip.Magnet off center point is far away more, and cursor is fast more movably.
Please refer to Fig. 3, for overlooking the synoptic diagram of magnet and 4 sensing stations.Wherein can comprise: magnet 301, sensor 302-1, sensor 302-2, sensor 302-3, sensor 302-4.When magnet was static, the magnetic flux that sensor 302-1, sensor 302-2, sensor 302-3, sensor 302-4 sense was the same, and this moment, magnet was positioned at initial point.When magnet moved with slide plate, as the residing position of magnet among Fig. 3, the magnetic flux that sensor 302-1, sensor 302-2 sense increased, and the magnetic flux that sensor 302-3, sensor 302-4 sense reduces, and can judge that in view of the above magnet moves to first quartile.According to the difference of sensor 302-1, sensor 302-2 magnetic flux change amount, can judge the angle of magnet.In the present embodiment, the transportable zone of slide plate is the circle of 1mm for radius, in the distance of 1mm, and according to the variation of magnetic flux, exportable 8 grades of sensor, when magnet is static, output 0, during magnet skew 1mm, output 7.The hall device induction module can be determined the position of magnet according to the numerical value of 4 sensor outputs.And the numerical value of sensor output is big more, and cursor is fast more movably.After externally applied forces on the slide plate disappeared, slide plate recoiled to initial point, and magnet is got back to initial point simultaneously, and the numerical value of sensor output diminishes, and ignore the numerical value of sensor output this moment, and cursor is static to be moved with slide plate at this until magnet.
For the capacitive sensing module:
The capacitive sensing device is mainly used in the induction metal membrane-coating and triggers or be released, if metal membrane-coating triggers or is released, then the result that will sense exports to by key control unit, generates key information by key control unit, and exports key information to main control chip.
The capacitive sensing device begins to detect from sensing the metal membrane-coating triggering, after if finger leaves metal film, sensing metal membrane-coating within the predetermined time triggers once more, then assert the generation of an actuation of keys, such as the right and left key function that realizes a mouse click, if recur actuation of keys within the predetermined time twice, then think to have produced a double-click.According to the different formed shapes of metal film, metal film can also be designed to have the button of specific function.
Illustrate the function that realization is clicked, double-clicked below.
For clicking, two distributions about metal film can be.Please refer to Fig. 4, be the process flow diagram of realizing clicking.
Step 401: metal membrane-coating triggers.
Step 402: the capacitive sensing device is sensed metal membrane-coating and is triggered, and the output high level is to pressing key control unit.
Step 403: metal membrane-coating discharges.
Step 404: the capacitive sensing device is sensed metal membrane-coating and is discharged, and output low level is to pressing key control unit.
Step 405: the respective pin by key control unit produces by high level to low level negative edge pulse.
Step 406: the negative edge pulse causes to be interrupted, and will click signal and be changed to 1, and pick up counting.
Step 407: the capacitive sensing device triggers to metal membrane-coating at the 1s internal induction, then to exporting high level by key control unit.
Step 408: judge that according to the high level that receives the operation that this time triggers the metal film execution is to click by key control unit.
Step 409: will click signal 1 and export main control chip to.
Step 410: main control chip is finished single-click operation according to clicking signal, finishes timing simultaneously, clicks the signal zero clearing.
In step 407, if the capacitive sensing device does not detect the metal membrane-coating triggering in 1s, then the capacitive sensing device will be clicked signal by key control unit according to low level and put 0 to by the key control unit output low level.Main control chip is not operated.
If left side metal membrane-coating triggers, execution be the function of left mouse button, if the right metal membrane-coating triggers, execution be the function of right mouse button.
For double-click, on above-mentioned basis of clicking, preestablish the time interval of knocking for twice, trigger metal film as long as in the time interval, finish twice, can realize the double-click function of mouse.If twice triggering in the time interval, do not think that then finishing twice clicks function.
According to the difformity that metal film presented, can also make device provided by the invention realize more functions of multiple keys, for example fly the shuttle operation.
In order to realize flying the shuttle operation, n sheet metal film can have multiple shape and can make up, and for example: metal film can be fan-shaped, and the fan-shaped metal film of multi-disc is arranged rounded.Each metal film is numbered according to 1-n, for example, can be according to clockwise each metal film being numbered.Every metal film connects a pin of capacitive sensing module, and for example sheet 1 connects pin one, and sheet 2 connects pin two ..., sheet n connects pin n.When the capacitive sensing module detected sheet 1 and is touched, the pin one of capacitive sensing module became high level, and the capacitive sensing module is to by high level of key control unit output.In the predefined time, if finger is drawn to sheet n according to clockwise direction from sheet 1, pin one-the n of capacitive sensing module becomes high level successively, then this operation has realized the function of left mouse button, otherwise, if according to counterclockwise drawing to sheet 1, the pin n-1 of capacitive sensing module becomes high level to finger successively from sheet n, then this operation has realized the function of right mouse button.
In addition, realize by the multi-disc metal film, can also make every metal film realize different functions, for example, can realize moving up and down of cursor, perhaps mobile menu bar etc. owing to fly shuttle operation.
