Embodiment

Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, wherein identical from start to finish or similar label is represented identical or similar elements, and perhaps, identical from start to finish or similar label represents to have the element of identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the utility model, and can not be interpreted as restriction of the present utility model.

Disclose the housing that a kind of keyboard and fore shell are structure as a whole in embodiment of the present utility model, it is applicable to the electronic product field, particularly uses the electronic product of keyboard input.Those skilled in the art also can carry out adaptability revision to keyboard structure or fore shell form according to applied electronic product when implementing the utility model.The utility model is that specific embodiment is described with the mobile phone, and the description of described specific embodiment is for exemplary purposes, and can not think the restriction to protection range of the present utility model.

Mobile phone of the present utility model comprises casing assembly and is installed in the interior electronic circuit board of casing assembly, casing assembly comprises front shell assemblies and back shell component, wherein front shell assemblies mainly comprises keyboard and fore shell, because technical characterictic of the present utility model on front shell assemblies, therefore is described in detail with regard to front shell assemblies.

Fig. 3 illustrates the cell phone keyboard of the utility model one specific embodiment and the housing that fore shell is structure as a whole.Described housing is the one-time formed integrative-structure of integral molded plastic, can adopt transparent PC (Merlon) material, ABS (acrylonitrile-butadiene-styrene copolymer), or the materials such as mixture of PC (Merlon) and ABS (acrylonitrile-butadiene-styrene copolymer) come injection moulding.In this specific embodiment, described housing is by transparent makrolon material injection moulding one-shot forming, as shown in Figure 4, guarantee the intensity and the toughness of housing, and simplified process, can use surface spray coating process or surperficial whole PVD electroplating technology, or IML technology, the keyboard of disposable realization housing and the exterior decorative effects of fore shell such as (In-Molding Label).The associative perception and the intention sense of decorative appearance have been strengthened.

In the described housing, the thickness of keyboard is littler than the thickness of fore shell.The plastic cement wall thickness of fore shell is 1.2mm, thereby guarantees the structural strength of fore shell; The plastic cement wall thickness of keyboard is 0.5mm, thereby the dynamics when reducing the finger presses keyboard has improved the comfortable feel degree of keyboard.Because the structure of housing is not a uniform wall thickness, the thickness is 1.2mm, thinnest part is 0.5mm, when mold injection, be easy to generate current mark and melt undesirable appearance phenomenon such as trace, for addressing this problem, when structural design, accomplish the even smooth variation of wall thickness, and when mold design, improve the position and the quantity of hole for injecting glue, thereby strengthen the plastic cement flowability.

As shown in Figure 5, be to guarantee the comfortable feel of keyboard, keyboard is adopted the design of linear slit cutting, form plurality of keys technology groove 10, groove width is 0.3mm, and described button technology groove 10 is divided into plurality of keys with keyboard, and described button is connected with keyboard portion, is structure as a whole.Such design can reduce the active force of finger presses button, and makes each button that certain elastic force all be arranged.

Described keytop convexes to form a curved surface 20, is basal plane with the button horizontal plane, and curved surface 20 summit dimplings go out basal plane 0.4mm, thereby has strengthened the feel that keyboard is pressed.

In the utility model, the keyboard in the housing and the thickness of fore shell, the width of button technology groove 10, and the height that curved surface 20 protrudes basal plane all can be not limited to numeral cited in the present embodiment according to the actual conditions adjustment.

As shown in Figure 6 and Figure 7, described mobile phone also comprises a silica gel lamella 30, described silica gel lamella 30 is between keyboard and electronic circuit board, each button back side of keyboard is provided with the projection 40 of one, be provided with pothole 50 with described projection 40 corresponding positions on the silica gel lamella 30, when the finger presses button, button is to bottom offset, by the cooperation of projection 40 and pothole 50, can make pothole 50 bottoms touch electronic circuit board, realize input operation, silica gel lamella 30 has guaranteed to push the elastic handfeel of keyboard, and guarantees the structural strength of button.

The housing that the utility model adopts Shooting Technique that keyboard and fore shell are structure as a whole, novel form, frame mode uniqueness, mobile phone number of components and parts and assembly process have been reduced, simplified the process to fore shell and keyboard, reduced manufacturing cost, the button feel is good.The utility model has been simplified process, can use surface spray coating process or surperficial whole PVD electroplating technology, or IML technology, the keyboard of disposable realization housing and the exterior decorative effects of fore shell such as (In-Molding Label).The associative perception and the intention sense of decorative appearance have been strengthened.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
