Abstract

The utility model is the application of using the carbon diaphragm flexible circuit in the aspect of the forced induction, in particular to the structure of a pressure-sensitive blanket with no requirement to the numerical value. The utility model is characterized in that the corresponding inner surfaces of two layers of basal pieces top and bottom are coated with conductive carbon diaphragm layers. A layer of perforated lamellar insulating lining is lined between the conductive carbon diaphragm layers to fix the two layers of basal pieces on top and bottom, and to divide the two layers of conductive carbon diaphragm layers, and the conductive carbon diaphragm layers are connected with conducting wires. The utility model can be applied to the places that need alarm device to alarm, coupled doors to lock or open and speech sound electric appliance to trigger and tip, such as the bank and the exchequer. The utility model applies the features of the carbon diaphragm flexible circuit technology, and offers a product which has the advantages of cheap fabricating cost, easy fabrication technology, easy use, strong durability, simple structure and comparatively strong applicability. The utility model is a comparatively perfect technical scheme in the application area that only need to check whether the pressure exists or not, but need not to check the numerical value of the pressure.

Description

The pressure sensitive blanket

Technical field

The utility model is with the application of carbon film flexible circuit aspect pressure sensitive, does not particularly have the structure of numerical value required pressure induction blanket.

Prior art

At present, generally all adopt the resistance strain gage sensing mode in the utilization of pressure sensitive sensing, be widely used in weigh, on the device such as dynamometry.The resistance strain gage sensor is a rigid structure, and there is the production and processing technology complexity in it, inconvenience is installed, shortcomings such as cost height.

But do not needing the detected pressures size, only needing whether the large tracts of land detected pressures exists, in the utilization such as cheap, easy for installation, still none desirable product can offer market at present, the carbon film flexible circuit for this class application requirements provides may.Use the pressure sensitive device of carbon film flexible circuit exploitation, can be used in antitheft, anti-invasion, anti-safety precaution field such as trail widely.Only needing a detected pressures whether to exist, do not need in the application of detected pressures magnitude numerical value, at present none comparatively perfect technical solution still.

Summary of the invention

The purpose of this utility model is, uses the characteristics of carbon film flexible circuit technology, and a kind of cheap, pressure sensitive blanket that manufacturing process is simple, easy to use, durable is provided.

Pressure sensitive blanket structure is, scribbles the conductive carbon rete on the inner face that two layers of substrate is relative up and down; Between the conductive carbon rete, serve as a contrast the laminar insulating cell fixed substrate of one deck perforate, and two layers of conductive carbon film are separated; The conductive carbon rete connects lead.

Hole on the laminar insulating cell can be 8～12 millimeters, and the hole center distance can be 16～24 millimeters.

Principle of work of the present utility model is, when the pressure sensitive blanket is not subjected to the external force extruding, promptly have no talent and on the pressure sensitive blanket, trample, pressure sensitive blanket two-layer conductive carbon rete up and down is equivalent to open circuit by the insulating cell of centre partition, control circuit is in original state, is infinitely great by the wire output end resistance at this moment.

When the pressure sensitive blanket is subjected to external force, trample thereon if any the people, middle foam mat is extruded, and two-layer up and down conductive carbon film forms the resistive loop about a 100-900 Ω by the tapping contact of insulating cell, in this resistance loop Access Control circuit, can make the relay conducting, output is often opened and normally closed many group switching value signals, removes to control speech control module, interlock control module, alarm control module, trigger burglar alarm and report to the police or the like, reach the control purpose.

The utility model can be applicable to, and need have warning device to report to the police, and linkage door locks or opens, and voice electrical equipment triggers places such as prompting, as: ground such as bank, national treasury.

The utility model has been used the characteristics of carbon film flexible circuit technology, and a kind of cheap, product that manufacturing process is simple, easy to use, durable is provided; It is simple in structure, and applicability is stronger.Only needing detected pressures whether to exist, do not need in the application of detected pressures magnitude numerical value, be a kind of comparatively perfectly technical scheme.

Specific embodiments

A kind of pressure sensitive blanket scribbles conductive carbon rete 3 on the relative inner face of upper strata substrate 2 and lower floor substrate 6; Between the conductive carbon rete, the laminar insulating cell 5 of lining one deck perforate is fixed two layers of substrate up and down, and two layers of conductive carbon film are separated; The conductive carbon rete connects lead 4.Be fixed with protective seam 1 and lower protective layer 7 at the outside surface of two layers of substrate up and down.Substrate is the terylene material, and the laminar liner of perforate is the sponge material, and upper and lower two-layer protective seam adopts rubber-like or polymeric type goods, waterproof and non-watertightly determine according to behaviour in service.The insulating cell hole shape is circular, and the aperture is 10 millimeters, and the hole center distance is 20 millimeters.Conductive carbon film is mixed by carbon dust and bonding agent and forms, and is sprayed on the mylar.But conductive carbon rete shape random geometry.

Conductive carbon film is sprayed on the geometric configuration that forms on the terylene substrate, according to concrete needs following geometric figure is arranged generally:

See accompanying drawing 3: spray type entirely.
