Embodiment
In order to solve the technical matters that contactor control device range of application is narrow, sensitivity is low, manufacture process requirement is high with plane touch-control surface of the prior art, the main technical schemes that the utility model adopts is: the flexible cavernous body that outside surface is set between housing and PCB circuit board is enclosed with one deck conducting film.
The cut-open view with contactor control device that can touch-control curved surface that Figure 1 shows that the utility model embodiment relates to, as can be seen from Figure, of the present utility model have can touch-control curved surface contactor control device 1 comprise the plastic casing 10 for accepting to touch that is provided with multiple touch controlled keys position, be provided with in the PCB circuit board 20 of capacitive touch control circuit and multiple multiple electrode points 21 that are fixed on described PCB circuit board 20 and the flexible cavernous body 30 contacting with the relevant position of described housing 10 another sides respectively, the outside surface of described flexible cavernous body 30 is enclosed with one deck conducting film 40, for convenience of description and observe, conducting film 40 in the utility model accompanying drawing and electrode points 21 are the effect after amplifying to a certain extent.Preferably, in the present embodiment, electrode points 21 is the conductive copper films being attached on PCB circuit board 20.
The one side for accepting the plastic casing 10 touching that is provided with multiple touch controlled keys position in this enforcement is provided with curved touch-control surface, and described multiple touch controlled keys position is positioned on described touch-surface.
In Fig. 1, the curved shape of touch-control surface is specially arc, in the variation shown in Fig. 2 touch-control surface bending be shaped as waveform, concrete bending shape can arrange according to the different demand of user and hobby.The optional use of material of housing 10 has the plastic cement of certain flexibility, touches sense and friction force to increase.The one side of housing 10 is also provided with multiple marking keys (not shown)s of selecting for function, and marking keys, corresponding to touch controlled key position, facilitates user to select operation.The touch controlled key position that several marking keys and respective amount can be set according to the number of function in daily use, in the present embodiment is 4, is 3 in the variation of the present embodiment.
Be provided with flexible cavernous body 30 in the another side of housing 10 position corresponding with each touch controlled key, its one end is closely pushed and is contacted with the another side of housing 10, the other end is fixed in the electrode points 21 of PCB circuit board 20, particularly, the other end of flexible cavernous body 30 closely pushes and contacts with the electrode points 21 on PCB circuit board 20.The outside surface of flexible cavernous body 30 is enclosed with one deck conducting film 40, particularly, conducting film 40 covers the whole outside surface of flexible cavernous body 30, contact with the another side of housing 10 and the electrode points 21 of PCB circuit board 20 respectively, conducting film 40 can be to have the netted gauze of conducting function or the fexible film being formed by conducting resinl.Therefore, housing 10 can be electrically connected with PCB circuit board 20 by the conducting film of cavernous body outside surface 40.And because conducting film 40 is attached on flexible cavernous body 30, flexible cavernous body 30 can be out of shape in its deformation range, space between housing 10 and PCB circuit board 20 can be filled by flexible cavernous body 30, even if the size in this space is because ectocine or touch action change, flexible cavernous body 30 also can utilize its deformability and deformation recovery capability by this space-filling, therefore, can ensure the close contact between flexible cavernous body 30 and housing 10 and the electrode points 21 of PCB circuit board 20, that is to say, the touch-control surface of housing 10, between conducting film 40 and PCB circuit board 20, can carry out stable electrical connection, ensure that contactor control device triggers the sensitivity of controlling, reduce the technology difficulty of manufacturing.In addition, because the area coverage of flexible cavernous body 30 is larger, therefore, the electrode points that is positioned at the key zone on housing 10 and be positioned on PCB circuit board 20 does not need accurate aligning, the capacitance variations sensing by conducting film 40 still can stably be conducted to PCB circuit board 20, reduce from another point of view the technological requirement that product is manufactured, saved cost.
The process of button touch-control is carried out in lower mask body introduction by the flexible cavernous body 30 that is enclosed with conducting film 40 being set between housing 10 and PCB circuit board 20.
The touch controlled key position of contactor control device is usually located in a touch-control surface touch-control surface, in the present embodiment, touch controlled key position is positioned in the touch-control surface of curved surface, when without any conductive body contact touch-control surface, conducting film 40 is responded to the capacitance variations less than touch-control surface, in the time that human finger touches the touch-control surface of housing, conducting film 40 senses the new electric capacity producing between human body and touch-control surface by touch-control surface, and send this capacitance variations to PCB circuit board 20 by conducting film 40, thereby send the controller of corresponding signal to PCB circuit board 20.
Concrete, touch-control surface is provided with multiple electrodes corresponding with touch controlled key position, between adjacent electrode, there is spurious capacitance, in the time contacting without any conductive body, between each electrode, all can have a fixing loose strays to hold, now the Electric Field Distribution between electrode and electrode is fixed, once conductive body contact touch-control surface, the total capacitance value from induction channels that PCB circuit board receives can change, and can determine concrete touch position by the variation of this total capacitance value.
In the time of marking keys on human finger touching housing, the electrode of touch-control surface with point between formed a new electric capacity, in addition, between adjacent electrode, also there is a coupling capacitance.Thus, originally the electric field of stationary distribution between electrode just can be connected to finger skin and change because of part line of electric force, and then changed the capacitance of touch-control surface.For example, in the time of single finger or single-point contact, have an X-axis line and a Y-axis line generation capacitance variation simultaneously, therefore just can obtain concrete position of touch by the coordinate common factor of X-axis and Y-axis.Above-described by the marking keys of finger contact housing, and cause the capacitance of touch-control surface to change, the variation of this electric capacity sends PCB circuit board 20 to by conducting film 40, thereby sends the controller of corresponding signal to PCB circuit board 20.
It will be understood by those skilled in the art that; these are only the embodiment of the utility model optimum; can be improved according to the above description or be converted, do not making the improvement of making under the prerequisite of creative work and converting the protection domain that all should belong to the utility model claims.
