Description
Technical field
The utility model is meant a kind of press-key structure with space pattern especially relevant for a kind of press-key structure.
Background technology
Progress and development along with science and technology, the consumer is for mobile phone or PDA(Personal Digital Assistant) now, the demand of super mobile personal computer electronic products such as (UMPC), also more and more tend to the shape-designing of personalization and sophistication, and these electronic product major parts all need to pass through button, just can reach the message transmission between user and the electronic product, and the user is for the button demand of electronic product, also constantly in seeking change and innovation, therefore how to develop and have more competitive button, to cater to popular at present general user demand, become the important topic that the button manufacturer is studied.
Known press-key structure, as Japanese disclosure of the Invention number is that the patent of 2000-340059 is disclosed, consult Fig. 1, this press-key structure mainly comprises bottom 10a, patterned layer 12a, superficial layer 14a and the coloured light transmission 17a that films, wherein the front of patterned layer 12a is convexly equipped with forming three-dimensional pattern 121a, superficial layer 14a then is provided with and aforementioned space pattern 121a corresponding matching groove, and superficial layer 14a is spliced on the front of patterned layer 12a; At the coloured light transmission of the back up of the patterned layer 12a 17a that films, bottom 10a then amplexiforms below light transmission is filmed 17a; So, to constitute press-key structure.
In addition, Japan's disclosure of the Invention number also discloses the press-key structure of another form for the patent of 2000-331554, itself and Japanese disclosure of the Invention number are the maximum difference point of the patent case of 2000-340059, it is the groove that forms space pattern in superficial layer inside, and be coated with the light transmission Coloured film in the groove inner surface, so as to going out space pattern in that superficial layer is inner visual.Yet aforesaid press-key structure is though have the display effect of space pattern, but it does not have the configuration of light guide plate, only can be applicable on minimal type or the single keycap to have the press-key structure of big region operation area, can not satisfy interim user demand for needs; In addition, Japanese disclosure of the Invention number is the patent case of 2000-340059, only prints at the space pattern end face, is difficult for allowing the moulded quilt of space pattern fully show, and makes its identification and aesthetic property not satisfactory.
In addition, Chinese patent notification number CN2544299Y discloses, it mainly comprises superficial layer, first patterned layer, refracting layer and second patterned layer, wherein superficial layer is a light penetrating object, first patterned layer is light tight body, be superimposed with this superficial layer is upper and lower, and be provided with first pattern that forms shape with the hollow out position; This refracting layer is semi-transparent body also, be positioned at the place, below of the superficial layer and first patterned layer, and the refracting layer below is formed with the back side; Second patterned layer is light tight body, is attached on the back side of refracting layer, and is provided with second pattern that forms shape with the hollow out position; And the light that utilizes luminescence component by the below of second patterned layer towards the projection of superficial layer direction, so that first and second pattern is presented on the superficial layer by printing opacity, to reach multiple display effect.Yet, aforesaid press-key structure, though have multiple display effect, it is by forming first and second pattern in first and second patterned layer, and make button to add gross thickness quite thick and heavy, and be not suitable on the electronic product of slimming day by day and lightness; Its luminescence component is formed at the below of second patterned layer in addition, more increases whole winding height, and makes the thickness of electronic product can't obtain reduction effectively; And its refracting layer is semi-transparent body, and makes shown identification and the visual effect that goes out of second pattern not satisfactory.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of press-key structure with space pattern that increases identification and aesthetic property.
In order to reach above-mentioned purpose, the utility model provides a kind of press-key structure with space pattern, comprise bottom, light guide plate, patterned layer, coating layer and superficial layer, wherein this light guide plate is spliced in the top of this bottom, this patterned layer is located at the top of this light guide plate, is provided with two or more space patterns on patterned layer; This coating layer is plating the upper surface in this patterned layer; This superficial layer splices in the top of this coating layer, and forms two or more keycaps corresponding to space pattern at this superficial layer.
As can be seen from the above technical solutions, press-key structure with space pattern of the present utility model, by each combining and configuring of forming assembly, patterns such as literal, symbol or figure can be revealed in keycap inside with three-dimensional form, and more increase visual effects such as identification and aesthetic property.
