The touching and keying device can lead a capacitive touching panel to comprise the metal structure, and form unified style with metal frames of various home appliances such as a television, a refrigerator, an air conditioner and the like, is wider in applicable situations and fields, and improves the operation convenience and attractiveness of applied products.
Description
Technical field
The utility model relates to touch button device, specifically the touch button device of capacitive sensing.
Background technology
Traditional capacitance type touch key structure; The touch panel of nonmetallic materials is set on the touch key-press surface; The key panel of touch panel and touch sensitive (KEYPAD) contacts for face; Its operation principle is: through operator finger the touching of touch panel is changed the capacitance between key panel (KEYPAD) and the human body, trigger control chip and move and realize.Key panel is a capacitance pole as capacitance type touch key, and human body is another capacitance pole, and (ε is a dielectric constant according to C=ε .A/D; A is an electrode area, and D is an electrode distance), when the finger near the time; Distance B will be dwindled between human body and the key panel, and capacitance will increase, when finger leaves; Capacitance will diminish, and control chip is sensed the variation of capacitance, sends corresponding instruction.If but when adopting the touch panel of metal; Formed electric capacity between the touch panel of key panel surface and metal; Because the touch panel of metal is to the shielding action of electric field; When finger near the time to not influence of the capacitance between touch panel and the key panel, therefore can't change the capacitance on key panel surface, thereby trigger not control chip.Therefore the touch panel of conventional condenser touch structure can only use nonmetallic materials such as plastics, glass; There is the panel that electrodeposited coating, gold stamping, metallic paint etc. contain metal ingredient all can't use for metal material, frosting; Influence the application and the occasion of touch key-press, also reduced the operation ease and the aesthetic property of many products.
The utility model content
The utility model provides a kind of touch button device, can make in the touch panel of capacitance type touch key to comprise metal structure, makes touch button device can be applicable to occasion and field widely, has improved the operation ease and the aesthetic property of application product.
The touch button device of the utility model comprises touch panel and key panel, wherein touch panel be include metal structure and through the touching can produce the panel of deformation, between touch panel and key panel, be provided with rigid insulation structure and dielectric.The effect of rigid insulation structure is the distance that makes touch panel and key panel certain at interval; The touch panel that has metal structure through touching makes it to produce deformation; Changed the distance between touch panel and the key panel; According to C=ε .A/D, thereby change the capacitance between touch panel and the key panel, triggered the control chip that is connected with key panel.
Concrete a kind of scheme is that described insulation system is the laminated structure of plastics, and is located at the edge near key panel, makes touch panel when touching, be easier to produce deformation, changes the spacing with key panel.
In order to make touch panel be easier to be pressed, preferred a kind of scheme is that the thickness that touch panel is set is 0.5mm.
On this basis, can be pressed easily in order to make touch panel, the dielectric between touch panel and the key panel should be gas or flexible colloid, solid etc., comprising air or rubber, also can be the gas or the flexible media of other insulation.
Further; According to different application scenarios; Touch panel can have multiple different structural forms, and to adapt to various environment, version wherein includes the panel of simple metal structure; Also can be the touch panel that has metal structure on the surface, can also be the inner packet metal-containing layer at traditional touch panel.
Wherein the metal structure on the touch panel surface can be the structure of the coat of metal or metal pattern, to increase more aesthetic.
The touch button device of the utility model; Can make in the touch panel of capacitance type touch key and comprise metal structure; Make touch button device form unified style with the metal edge frame of various electrical equipment such as TV, refrigerator, air-conditioning; The occasion and the field that are suitable for are more extensive, and have improved the operation ease and the aesthetic property of application product.
Below in conjunction with embodiment, the foregoing of the utility model is remake further detailed description by the accompanying drawing illustrated embodiment.But should this be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following instance.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the utility model.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model touch button device.
Embodiment
As shown in Figure 1; The utility model touch button device; Comprise touch panel 1 and key panel 2; Touch panel 1 for include metal structure and can produce the panel of deformation through touching, described metallic magnetism includes the structure that simple metal structure, surface have the inner packet metal-containing layer of metal structure or touch panel, to adapt to different application scenarios.The thickness of touch panel 1 is 0.5mm.Between touch panel 1 and key panel 2, be provided with the dielectric 4 of sheet rigid insulation structure 3 and the air or the flexible rubber formation of plastics.
The effect of the sheet rigid insulation structure 3 of plastics is the distances that make touch panel and key panel certain at interval, makes touch panel 1 and key panel 2 form the two poles of the earth of electric capacity.After touch panel 1 that operator touching has a metal structure makes it to produce deformation; Promptly changed the distance between touch panel 1 and the key panel 2; According to C=ε .A/D; Also just change the capacitance between touch panel 1 and the key panel 2, triggered the control chip (not shown) that is connected with key panel 2.Like this; Can make and comprise metal structure in the touch panel 1 of capacitance type touch key or all constitute by metal; Make touch button device form unified style with the metal edge frame of various electrical equipment such as TV, refrigerator, air-conditioning; The occasion and the field that are suitable for are more extensive, and have improved the operation ease and the aesthetic property of application product.
