Abstract
The invention provides a keyboard on an electronic product, wherein the electronic product is provided with a casing and a circuit board. The keyboard comprises a first elastic body and a hard body which is positioned on the upper surface of the first elastic body, a projection on the first elastic body protrudes toward the circuit board, the casing is provided with a positioning portion, the keyboard is provided with an engaging portion engaged with the positioning portion for positioning, and the upper surface of the hard body is provided with a second elastic body. The upper surface of the keyboard is equipped with the elastic bodies, thereby realizing excellent sense of touch of the whole keyboard.
Description
Technical field
The present invention relates to a kind of keyboard, particularly a kind of good keyboard of feel of pushing.
Background technology
Along with the continuous development of science and technology, the portable type electronic product with input function is more and more, for example mobile phone, electronic dictionary, PDA (Personal Digital Assistant, personal digital assistant) etc.These electronic products constantly develop to miniaturization and ultra-thin direction, to be convenient for carrying.Keyboard shared large percentage on the volume of whole electronic product plays crucial effects to the miniaturization development of device, and the thickness of keyboard will directly have influence on the thickness of whole device, and simultaneously, keyboard also should have a good location to cooperate with housing.
Fig. 1 shows the sectional view of a kind of keyboard of prior art.This keyboard comprises elastomer 2, is positioned at the duromer 1 of elastomer 2 upper surfaces, forms a plurality of projections 11 on the lower surface of elastomer 2.Duromer 1 adopts steel disc class hard material to make, handle through the processing bending steel disc and electronic product casing both sides, bending goes out the location division (not shown) with the electronic product casing location, by the location division, makes keyboard and electronic product casing have a good location to cooperate.If the user presses down keyboard, then duromer 1 produces deformation, impels the projection 11 that is positioned at elastomer 2 lower surfaces to press down corresponding conductivity dome 4 on the circuit board, makes that corresponding contact element 31 electrically contacts on dome 4 and the circuit board 3.
Because the duromer 1 in the above-mentioned keyboard selects for use steel disc class hard material to make, such keyboard has ice-cold sensation in the process of using, and sense of touch is very poor, thereby has reduced the comprehensive use index of whole money mobile phone.In addition, for making keyboard and housing have a good location to cooperate, above-mentioned steel disc will be processed bending and handle, bending goes out the locating surface with the housing location, this bending and forming technology is comparatively complicated, and the button face of metal sheet is yielding in the process of bending, causes levelness to reduce, but also need the extra one button face flattening process step of adding, could guarantee that keyboard has the good horizontal degree.
Summary of the invention
Embodiment of the invention technical problem to be solved is to provide a kind of good keyboard of feel of pushing.
The embodiment of the invention is to realize like this, a kind of keyboard, be positioned on the electronic product, electronic product has housing and circuit board, keyboard comprises first elastomer and is positioned at the duromer of the first elastomer upper surface, stretches out projection to the circuit board direction on first elastomer, has the location division on the housing, keyboard is provided with the auxiliary section that cooperates the location with described location division, and the duromer upper surface is provided with second elastomer.
Technique scheme, compared with prior art, owing to be provided with second elastomer at the duromer upper surface of keyboard, thus make that the sense of touch of whole keyboard is good.Simultaneously, because keyboard has duromer, make keyboard not lose its intensity again.

Embodiment
In order to make the technical problem to be solved in the present invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention provides a kind of and existing keyboard to compare, and pushes the good keyboard of feel, and for this reason, the keyboard that the embodiment of the invention provides is provided with second elastomer at its duromer upper surface.
As shown in Figure 2, the keyboard of a preferred embodiment provided by the invention is positioned on the electronic product, and electronic product has housing 5 and circuit board 9.Have contact element 91 on the circuit board 9, circuit board 9 tops be provided with behind the pressurized can with contact element 91 contacted conductivity domes 8.Keyboard comprises first elastomer 72 and is positioned at the duromer 6 of first elastomer, 72 upper surfaces that duromer 6 selects for use this area common materials to make, for example plastic cement, metal steel disc etc.Have the projection 721 that is used with corresponding conductivity dome 4 on first elastomer 72, have location division 51 on the housing 5, location division 51 is a projection that is come out by projection on the housing 5; Keyboard is provided with the auxiliary section 722 that cooperates the location with location division 51, and auxiliary section 722 is extended by the bending of duromer 6 ends and formed, and is used with location division 51 keyboard is fixed on the housing 5.Duromer 6 upper surfaces also are provided with second elastomer 71, like this, make that the sense of touch of whole keyboard is good.
Fig. 3 to Fig. 5 has shown the keyboard of three kinds of preferred embodiments in addition provided by the invention.The keyboard of these three kinds of preferred embodiments, its first elastomer and second elastomer are an integral, flexible body 7 of being made by flexible glue, and it can be one-body molded, duromer 6 by sheet material directly cutting form, be encapsulated in the integral, flexible body 7.Because integral, flexible body 7 is made by flexible glue, can adopt the method for injection moulding or oil pressure.Form the auxiliary section 722 that cooperates with location division 51 on the housing in elastomer 7 ends.Like this, the concrete structure of auxiliary section 722 is easy to be designed to respective shapes according to the structure of housing location division 51, for example, has shown a kind of shape of corresponding auxiliary section 722 of the structural design according to different housings location division 51 among Fig. 3, Fig. 4 and Fig. 5 with regard to each.Certainly, location division 51 structure differences on the housing, the shape of then corresponding auxiliary section 722 also can be designed to difference, and therefore, the concrete structure of auxiliary section 722 is not limited to above-mentioned three kinds of structures.
For keyboard of the present invention, directly the elastomer time processing is molded the locating surface of locating with electronic product casing, reduced processing step, improved production efficiency.In addition, the locating surface height can carry out the furnishing conversion according to designing requirement, has improved design freedom greatly.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
