Abstract
The utility model relates to a light guide key panel used for an electronic product, which comprises a plastic light guide substrate, one lateral surface of which is printed with a character-or point-shaped light guide ink part, and the other lateral surface of the light guide substrate is correspondingly printed with a mark layer, so as to form an integral type light guide key panel. The position of the lower surface of the integral type light guide key panel corresponding with each key is also printed and molded with a protuberance which can be resisted against a corresponding membrane switch. The utility model prints the light guide ink part used for reflecting light at one side of the plastic light guide substrate and prints and molds the mark layer at the other side to be used for marking the characters expressed by each key, so as to form the integral type light guide key panel which has a simple structural layer, is convenient for producing and can reduce the production cost effectively.
Description
Technical field
The utility model relates to a kind of light guide plate, refers in particular to a kind of light guide key panel of use for electronic products.
Background technology
The key panel of existing electronic product many by button, be used to illuminate the lamp of button and silica gel projection three parts that can cooperate with corresponding diaphragm switch constitute, this key panel structure complexity is assembled time-consumingly, production cost is higher.
The utility model content
Technical problem to be solved in the utility model is: a kind of light guide key panel of use for electronic products is provided, and it is simple in structure, is convenient to produce, and can effectively reduce production costs.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of light guide key panel of use for electronic products, the light guide base plate that comprises plastic material, one side surface of described light guide base plate is printed with the light guide ink portion of literal or point-like, and correspondingly on light guide base plate opposite side surface is printed with label layer and forms one-piece type light guide key panel.
Further improvement in the technical proposal is: the downside surface of described one-piece type light guide key panel corresponding to each place, button position also printing form the projection that can press on the corresponding diaphragm switch.
The beneficial effects of the utility model are: by be used for the light guide ink portion of refracted ray in the light guide base plate one side printing of a plastic material, and the opposite side printing forms label layer, be used to identify the character of each button representative, thereby form one-piece type light guide key panel, its structure sheaf is simple, be convenient to produce, can effectively reduce production costs.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the cross-sectional view of light guide key panel first execution mode of the utility model use for electronic products.
Fig. 2 is the cross-sectional view of light guide key panel second execution mode of the utility model use for electronic products.
Embodiment
See also Fig. 1, in first execution mode of the light guide key panel of a kind of use for electronic products of the utility model, described light guide key panel comprises the light guide base plate 1 of plastic material, and described light guide base plate can adopt in the following material any one to make: PC, PET, PMMA, PU.The downside surface of described light guide base plate 1 is printed with the light guide ink portion 2 of literal or point-like, and is printed with the character that label layer 3 is used to identify each button representative in that light guide base plate 1 uper side surface is corresponding, thereby forms one-piece type light guide key panel.The downside surface of described one-piece type light guide key panel corresponding to each place, button position also printing form the projection 4 that can press on the corresponding diaphragm switch (scheming not shown).Described projection can adopt thermohardening type material or drying type UV gel-type resin to make.And described light guide ink portion equally also can adopt thermohardening type material or drying type UV gel-type resin to make, and the thermohardening type material that is used for printing shaped projection and light guide ink portion can be any one of following material: epoxy resin, polyurethane or silica gel.
In the utility model shown in Figure 2 second execution mode, the main distinction of itself and last execution mode is, the location swap of described light guide ink portion 2 and label layer 3, that is: 2 printings of light guide ink portion take shape in the uper side surface of light guide base plate 1, and label layer 3 takes shape in the downside surface of light guide base plate 1, correspondingly, described projection 4 still takes shape in the downside surface of one-piece type light guide key panel, and promptly be positioned on the lower surface of label layer 3 this moment.In the present embodiment, light refraction can be illuminated the label layer of key panel equally in light guide ink portion 2, so that operation push-button.
