Abstract
An ultra-thin keyboard mainly relates to the field of computer product manufacturing, and relates in particular to a computer keyboard. The ultra-thin keyboard mainly comprises a film key cap, a solid flexible glue layer, and film circuits. The film key cap is positioned at the top of the keyboard. The solid flexible glue layer is arranged to be adhered to the film key cap along a lower surface of the film key cap. The solid flexible glue layer is downwardly provided with a protruding contact corresponding to a middle position of the film key cap. The two film circuits are fixed below the solid flexible glue layer. The solid flexible glue layer is a silicon rubber layer or other flexible glue layer. A first double-sided adhesive is arranged between the solid flexible glue layer and the film circuits. A second double-sided adhesive is arranged between the two film circuits. Holes are provided on the first double-sided adhesive and the second double-sided adhesive corresponding to the position of the film key cap. An elastic material layer of the keyboard is integrally made together with the film key cap through a mold, so that the thickness of the keyboard becomes very small and can be controlled to be less than 2 mm, and the keyboard can be folded to facilitate carrying.
Description
Technical field
The utility model relates generally to computer product and makes the field, refers in particular to a kind of computer keyboard.
Background technology
At present, keyboard is the most frequently used input equipment, and the electronic products such as computer, calculator, mobile phone all are to carry out the data input by keyboard, and along with developing rapidly of electronic product, the application of keyboard is also more and more extensive.Our keyboard of use is desktop keyboard mostly now, desktop keyboard mainly is comprised of the silicon rubber cup under keycap, the keycap, support and thin film circuit, support under the keycap links up keycap and substrate, but because support is hard material, the thickness of the keyboard that becomes with rack making is larger, also can't convolution, carry inconvenience.
Summary of the invention
The defective work that causes for overcoming above-mentioned prior art, the utility model provide a kind of keyboard thickness very little, roll-up portable keyboard.
The technical scheme that the utility model adopts is:
Ultra-thin keyboard, mainly by the film keycap, solid-state flexible glue layer and thin film circuit form, the film keycap is positioned at the top of keyboard, solid-state flexible glue layer is close to the setting of film keycap along the lower surface of film keycap, solid-state flexible glue layer correspondence film keycap centre position to having the projection contact, the first film circuit is positioned at solid-state flexible glue layer below, the second thin film circuit is positioned at the first film circuit below, be provided with the first double faced adhesive tape between solid-state flexible glue layer and the first film circuit, the position of corresponding film keycap is offered porose on the first double faced adhesive tape, be provided with the second double faced adhesive tape between the first film circuit and the second thin film circuit, the position of the corresponding film keycap of the second double faced adhesive tape is offered porose.
The layer of silica gel of solid-state flexible glue layer for being formed in one by mould and film keycap.
Compare with conventional art, the utility model has the advantage of:
The elastomeric material of keyboard directly by mould with film keycap and the one-body molded making of silica gel, replaced keycap and the support in the conventional art, the less thick of keyboard, install easier, but and convolution, be convenient for carrying.
Description of drawings:
Fig. 1 is the section decomposing schematic representation of the keyboard that in the past used.
Fig. 2 is decomposing schematic representation of the present utility model;
Fig. 3 is the section decomposing schematic representation of button of the present utility model.
Embodiment:
Below in conjunction with drawings and the specific embodiments the utility model is described:
Fig. 1 is the section decomposing schematic representation of the keyboard that in the past used, the button of keyboard commonly used mainly was comprised of the silicon rubber cup 8 under keycap, the keycap, support 7 and thin film circuit in the past, support 7 under the keycap links up keycap and thin film circuit, but because support 7 is hard materials, the thickness of the keyboard that is made into support 7 is larger, also can't convolution, carry inconvenience.
Shown in Fig. 2 ~ 3, the utility model is mainly by film keycap 1, solid-state flexible glue layer 2, the first film circuit 4 and the second thin film circuit 6 form, film keycap 1 is positioned at the superiors of keyboard, solid-state flexible glue layer 2 is positioned at film keycap 1 below, solid-state flexible glue layer 2 is close to the lower surface setting of film keycap 1 along the lower surface of film keycap 1, the centre position of corresponding film keycap 1 is to having projection contact 201 on the solid-state flexible glue layer 2, solid-state flexible glue layer 2 directly by silica gel by mould and the 1 one-body molded making of film keycap, solid-state flexible glue layer 2 has the first film circuit 4 and the second thin film circuit 6, the second thin film circuit 6 is positioned at the first film circuit 4 belows, be provided with the first double faced adhesive tape 3 between solid-state flexible glue layer 2 and the first film circuit 4, the position of the first double faced adhesive tape 3 corresponding keycaps 1 is offered porose, be provided with the second double faced adhesive tape 5 between the first film circuit 4 and the second thin film circuit 6, the position of the second double faced adhesive tape 5 corresponding keycaps 1 is offered porose, the position of the corresponding keycap 1 of the first film circuit 4 lower surfaces upwards is provided with the second contact 601 to the position that has the corresponding keycap 1 of the first contact 401, the second thin film circuits, 6 upper surfaces.
The course of work of the present utility model is: when pressing film keycap 1, the backward lower motion that suffers oppression of solid-state flexible glue layer 2, projection contact 201 also moves downward, projection contact 201 compressing the first film circuit 4, deformation occurs in the first film circuit 4, thereby so that the hole that the first contact 401 on the first film circuit 4 is passed on the second insulation rubber 5 contacts with the second contact 601 on the second thin film circuit 6, thereby produced a push button signalling.
Because the elastomeric layer of keyboard directly by mould and film keycap 1 one-body molded being made into, has replaced keycap and the support in the conventional art, the less thick of keyboard, install more convenient, but and convolution, be convenient for carrying.
