Abstract
The invention provides an integrated film keyboard. The film keyboard comprises a keypad panel, a lower-layer polyester film and a back plate. The keypad panel is formed by the interconnections of integrated silicone rubber keypads through a connecting part, the lower surface of the keypad panel is provided with a printed circuit, and each integrated silicone rubber keypad comprises an integrated keypad cover at the top and a base skirt edge at the bottom. Balance staff columns are arranged in the base skirt edges, and the lower surfaces of the balance staff columns are matched with the shape of touch spots of the lower-layer polyester film. According to the film keyboard, the function of the silicone rubber keypads and the keypad covers and the function of an upper-layer polyester film switch and a separating sheet are combined together, assembly procedures are reduced, and the defect of keypad falling of the keypad covers is overcome, so that a notebook keyboard is lighter and better in hand feeling.
Description
Technical field
The present invention relates to a kind of input unit using manual operation switch, be specifically related to a kind of one membrane keyboard.
Background technology
As shown in Figure 1, comprise keycap 1, scissor 2, silica gel push-button 3, polyester film switch and backboard 5, wherein polyester film switch has upper strata 4-1 to keyboard of notebook computer of the prior art, the lower three-decker of partition 4-2 and lower floor 4-3.Partition 4-2 has the partition hole 4-4 matched with silica gel push-button 3 internal cavity, and silica gel push-button 3 chamber central has a day stem, the key point one_to_one corresponding on this day stem and polyester film switch.During manufacture, man-made assembly is passed through after keycap 1, scissor 2 and silica gel push-button 3 are shaping respectively, especially the assembling procedure of scissor 2 is comparatively loaded down with trivial details, easy appearance is bad, and causing the thickness of keyboard of notebook computer superstructure thicker, the one membrane keyboard designing a kind of designs simplification has become technical problem urgently to be resolved hurrily.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of one membrane keyboard.
Technical scheme: for solving the problems of the technologies described above, one membrane keyboard provided by the invention, comprise the key panel, lower floor's polyester film and the backboard that connect successively, described key panel is interconnected by one silica gel push-button and forms, the lower surface of described key panel has printed wire, described one silica gel push-button comprises the one keycap at top and the base shirt rim of bottom, has a day stem in described base shirt rim, the bottom surface of described sky stem and the shape of lower floor's polyester film contact suitable.
As preferably, the surrounding of described one keycap has the outward flange of protrusion.
As preferably, described printed wire is the silver-colored line of printing.
As preferably, described printed wire is coppered wire.
During manufacture, existing silica gel push-button is made silica gel push-button and keycap integral type, and by multiple silica gel push-button all-in-one-piece key panel, adopt and print silver-colored line (or copper facing) at lower floor's polyester film, the bottom of upper strata key panel prints silver-colored line or copper facing replaces existing upper strata polyester film and silica gel push-button, the connecting portion of silica gel push-button replaces original spacer layer, button conducting after pressing.The function of existing upper strata polyester film, silica gel push-button, keycap is integrated on new silica gel push-button, and is connected with each other between silica gel push-button and plays partition effect.When silica gel push-button ejection formation, silica gel push-button base shirt rim is connected together and empties replacement spacer layer at button place, the general size of KEY point on sky stem and polyester film, above silica gel push-button, make hard material, and printing spraying numeral or English alphabet etc.
Beneficial effect: the present invention adopts brand-new design concept, the effect of silica gel push-button and keycap and upper strata polyester film is combined, simplify operation (scissor, keycap, upper strata polyester film and spacer layer need not be assembled), decrease bad (keycap falls key), feel better (sky stem is the same with KEY point very much not have assembly deviation cause button bad), having saved material (silica gel push-button instead of one deck polyester film, spacer layer, silica gel push-button, keycap, scissor) makes keyboard of notebook computer thinner, lighter.
Except technical problem, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the present invention recited above solves, the advantage that the other technologies feature comprised in the other technologies problem that one membrane keyboard of the present invention can solve, technical scheme and these technical characteristics bring, will be described in more detail by reference to the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing keyboard of notebook computer;
Fig. 2 is the structural representation of the one membrane keyboard of the embodiment of the present invention;
Fig. 3 is the partial enlarged drawing of key panel in Fig. 2;
In figure: 1 keycap, 2 scissors, 3 silica gel push-buttons, 4-1 upper strata, 4-2 partition, 4-3 lower floor, 4-4 partition hole, 5 backboards, 6 one silica gel push-buttons, 6-1 base shirt rim, 6-2 days stems, 6-3 one keycap, 6-4 connecting portion.
Embodiment
Embodiment:
The one membrane keyboard of the present embodiment as shown in Figure 2, comprises key panel, polyester film switch lower floor 4-3 and backboard 5, and wherein key panel is by the interconnective multiple one silica gel push-button 6 of connecting portion.One silica gel push-button 6 chamber central has a day stem, the key point one_to_one corresponding on this day stem and polyester film switch.
As shown in Figure 3, one silica gel push-button 6 in key panel comprises the one keycap 6-3 at top and the base shirt rim 6-1 of bottom, connecting portion 6-4 bottom it is interconnected, and wherein one keycap 6-3 has the outward flange of protrusion, has a day stem 6-2 in the 6-1 of base shirt rim.At the lower surface of key panel, there is printed wire, make it instead of existing upper strata polyester film switch.
Lack upper strata polyester film, partition, keycap and scissor in the current industry of structural rate of the present embodiment, simplified production process, saved material, reduce key and feel is bad.Make keyboard of notebook computer lighter and thinner, adapt to the development in epoch.
Below by reference to the accompanying drawings embodiments of the present invention are described in detail, but the present invention is not limited to described execution mode.For those of ordinary skill in the art, in the scope of principle of the present invention and technological thought, multiple change, amendment, replacement and distortion are carried out to these execution modes and still falls within the scope of protection of the present invention.
