Abstract

The utility model relates to a light-transmitting rubber key with characters and patterns, comprising a key body with elastic soft material, a light-transmitting coating layer, a light-proof coating layer and a light source. The structure is mainly that the light-transmitting coating layer is coated on the key body; the light-proof coating layer is coated on the light-transmitting coating layer by baking; patterns or characters are carved on the light-proof coating layer by laser; the patterns or the characters are displayed by the light-transmitting coating layer under the irradiation of the light source in order that the utility model can be used conveniently at night or at the time of inadequate light.

Description

Lighting rubber key with character pattern

General rubber key does not on the market all have the printing opacity design, only can make and adopt the various products (computing machine, connector, game machine etc.) of rubber key to use daytime, then must there be the light fixture can if use night, so the user then can't use in the place that light fixture or insufficient light are not arranged, cause applicability limited, practicality thereby be greatly affected.

In view of this, but the purpose of this utility model provide a kind of in night the mat light source make pattern or literal printing opacity on the rubber key, but be convenient to the user in equal font pattern Nonopaque type rubber key of easy operating any time.

The structure of font pattern Nonopaque type rubber key of the present utility model includes:

Soft keying body has elasticity, and can be convexly equipped with a plurality of convex bodys of various difformities and size on demand on keying body, forms a pliability interval between convex body and keying body;

The printing opacity dope layer is evenly coated on the soft keying body;

Light tight dope layer is evenly coated on the printing opacity dope layer, has required pattern or font with laser engraving and removal on this light tight dope layer;

Light source is positioned at soft keying body below, makes the printing opacity dope layer manifest required pattern or font under the light projection, uses to be convenient to the operator when night or light are not enough.

Now in conjunction with the accompanying drawings with regard to structure explanation of the present utility model as back:

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is stereoscopic figure of the present utility model.

Fig. 3 is that the utility model is used in the embodiment stereographic map on the computing machine.

Fig. 4 is sectional plain-view drawing of the present utility model (one).

Fig. 5 is sectional plain-view drawing of the present utility model (two).

Fig. 6 is a process flow diagram of the present utility model.

Consult Fig. 1,2, by Fig. 1,2 font pattern of the present utility model as can be known Nonopaque type rubber key; Include:

Soft keying body 1 has elasticity, and can be convexly equipped with the convex body 11 of a plurality of various difformities and size on demand on keying

body

1, and 1 of convex body 11 and keying body form a pliability interval 12;

Printing opacity dope layer 2 is evenly coated on the soft keying body 1, is dried in the ventilation heating chamber;

Light tight dope layer 3, evenly coat on the printing opacity dope layer 2, on this light tight dope layer 3, carve required pattern or font again,, see shown in Figure 3 so that pattern of being scribed or font display by described printing opacity dope layer 2 under the rayed of bottom with laser engraving machine;

Light source 4 is positioned at soft keying body 1 below;

Said structure, the mat laser engraving machine is according to pattern required on the printing opacity dope layer 2 or font, carve and remove the corresponding site on the light tight dope layer 3, thereby make the printing opacity dope layer directly manifest required pattern or font, so that rubber key is when night or light deficiency, but the projection of mat light source makes pattern or font high-visible, so that the operator uses.

Light source of the present utility model can be luminous and substitute as the equivalent elements of light source with bulb or LED or other.

The utility model light source can be established one or more on demand.

The utility model elastomeric flexible rubber body 1, the available silicon resin, or other materials with equivalence substitute.

The utility model rubber key can apply to computing machine, and telephone set remote controller, game machine etc. must have on the various products of button.

Consult Fig. 5, the structure of the utility model font pattern Nonopaque type rubber key is made as shown in Figure 5.
