Abstract
The utility model discloses an inductor inductance type touch press key, which comprises an inductor type touch sensor and a single chip measuring control circuit, wherein the inductor type touch sensor consists of panels and a circuit board, the panels are tightly fixed, an inductance coil is distributed on the circuit board, and one side of the panels, which is in contact with the circuit board, is provided with a circular accommodating cavity with the radius larger than the inductance coil. The utility model does not depend on the human body or filed effect, and the pressure exerted on a press key is irrelevant with the attribute of objects, so the utility model can be used on electric products which need metal panels made of stainless steel, aluminum and the like and require seamless sealing on the external appearance, and the external appearance design of the products can be of much variety. In addition, because triggering mechanisms are different, the inductor inductance type touch press key still has stable and reliable work under the situation of humid environment or operation by operators with gloves.
Description
Technical field:
The utility model relates to touch induction technical field, especially relates to a kind of touch key-press of judging triggering by the variation of measuring the electromagnetic induction energy.
Background technology:
As a kind of replacement scheme of conventional button formula user interface, touch sensing is used and is applied in more and more on the various electronic products, not only can improve reliability, and touch sensing also helps to realize sealing fully and being imbued with the design of modern sense.At present most widely used is the capacitance touch sensing technology, but its triggering is the capacity effect that relies on human body, having determined it to be not suitable for being applied to key panel is metal material and the occasion that requires sealing, thereby need seek another scheme in this application scenario and replace the capacitor induction type touch key-press.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of inductance induction type touch key-press is provided that it can be applicable on the household appliances of appearance requirement sealing, and working stability is reliable.
For achieving the above object, inductance induction type touch key-press of the present utility model includes inductance type touch sensor and single chip computer measurement control circuit, wherein, the inductance type touch sensor is made of panel that closely is fixed together and the circuit board that is distributed with induction coil, and the one side that panel contacts with circuit board offers the circular containing cavity of radius greater than induction coil.
The position of the corresponding containing cavity of described panel surface offers the external diameter annular pocket consistent with induction coil.
Pass through screw or adhesive securement between described panel and the circuit board together.
The beneficial effects of the utility model are: it does not rely on human body or field effect, the attribute of applied pressure and object is irrelevant on button, therefore can be applicable to metal deckings such as needing to adopt stainless steel or aluminium and on the electric product of the seamless sealing of appearance requirement, make the appearance design scheme variation more of product; Secondly, because the mechanism that triggers is different, inductance induction type touch key-press is worn under the occasion of gloves operation in humidity or user, and its work is still reliable and stable.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a system configuration schematic diagram of the present utility model;
Fig. 2 is the decomposition texture schematic diagram of inductance type touch sensor of the present utility model;
Fig. 3 is the sectional structure schematic diagram of metal decking of the present utility model;
Fig. 4 is the operation principle schematic diagram of inductance type touch sensor of the present utility model.
Embodiment:
The following stated is preferred embodiment of the present utility model, does not therefore limit protection range of the present utility model.
See that accompanying drawing 1 is to shown in the accompanying drawing 4: inductance induction type touch key-press of the present utility model includes inductance type touch sensor 10 and single chip computer measurement control circuit 20, wherein, inductance type touch sensor 10 is made of panel 11 and the circuit board 12 that is distributed with induction coil 121, and panel 11 is in the same place by screw or adhesive securement with circuit board 12.The one side that panel 11 contacts with circuit board 12 offers the circular containing cavity 111 of radius greater than induction coil 121, and the position of panel 11 surperficial corresponding containing cavities 111 offers the consistent annular pocket with certain width and degree of depth 112 of external diameter and induction coil 121.
Operation principle of the present utility model is: after staff is pressed on the panel 11, panel 11 can produce small crooked deformation, the induction coil 121 of panel 11 on circuit board 12 drawn close, cause the magnetic flux generation minor variations between panel 11 and the circuit board 12, and then causing that the electric current in the induction coil 121 produces minor variations, system judges thus to have produced once and touches.
