Background technology
The crowd of sitting, office crowds and motor vehicle of driving over a long distance for routine work is inevitable position.The harm of sitting it is generally known that, producing cause partially due to fix a posture and make lumbar soft tissue for a long time inPower state, soft tissue ischemic, and lumbar muscle strain is generated, lasting compressing can so that buttocks, anus portion muscle ischemic, microcirculation are obstructed,Muscle, soft tissue hyperemia, swelling, the serous effusion for finally resulting in progressive increase, and bursal synovitis occurs in coxa joint, delayWith the passing of time hydrops will become sticky, muddy, cellulose is calm and sticks together, and then nerve is caused to test inflammation, bring a series ofComprehensive illness.
What existing cushion used is to increase the environment temperature of waist buttocks to controlling scheme one, accelerates blood circulation, two are to providePart massage function accelerates blood circulation.
Such as application No. is 201210328347.X, applying date 2012-09-07, it is entitled that " one kind is with heatingWith the seat cushions of pressure sensing function " technical solution in, disclose a kind of with heating and the automobile of pressure sensing functionSeat cushion includes the pressure sensor of setting on cushion, it is characterised in that the pressure sensor includes the plastics being correspondingly arrangedFilm layer prints aluminium foil layer conducting channel, carbon slurry conductive layer successively on plastic film layers, and the carbon slurry conductive layer includes sensingCircuit and heater circuit are printed on the plastic film layers of printed circuit by interlayer cohesive together, and forming composite structure is describedThe multiple repeatable sensing units for measuring load on automotive seat of setting in composite construction；Pressure sensor end is sealed with plastic cementBlock is connected, and the machine core board that the resistance value signal of each sensing unit is carried out to classification processing is arranged in the plastic cement sealing block, describedMachine core board is connected with vehicle air bag electronic management system.
Carbon slurry conductive layer heater circuit is made of temperature-sensitive carbon slurry in above-mentioned technical proposal.
Temperature-sensitive carbon slurry is that PTC carbon is starched in above-mentioned technical proposal.
Aluminium foil layer conducting channel in above-mentioned technical proposal is prepared by aluminum corrosion method, the aluminum corrosion method packetInclude following step：Suitable protection liquid is printed in aluminium foil layer conducting wire, is then applied in aluminium foil layer conductive circuit surfaceAfter corroding corrosion 1-10min, then with lye wash off protection liquid.
The thickness of aluminium foil layer in above-mentioned technical proposal is 3~30 μm.
Corrosive liquid in above-mentioned technical proposal is hydrochloric acid.
Concentration of hydrochloric acid is 25~30wt% in above-mentioned technical proposal.
It is Animal Bone colloid extracting solution that liquid is protected in above-mentioned technical proposal.Heating cushion is combined with pressure sensor,Keep installation easier, shape is more succinct；Using classification pressure sensor design, controls air bag pop-up amount and occupant is reminded to fastenSafety belt more effectively ensures the life security of passenger；Metal conducting layer uses aluminium foil, reduces production cost, savesResource；It avoids and forgets to occur the case where closing heater switch, storage battery electricity is caused to exhaust and automobile can not be started；With addingIt is automatically stopped the function of heating when heat is up to the maximum temperature set, prevents sensor heating temperature from being caused to occupant more than the upper limitHealth cost；Sensor uses the design of metal aluminum foil, and toughness higher, the service life is longer.
When there is passenger riding, circuit is constituted between sensor harness I and sensor harness II, pressure sensor is then by phaseThe resistance value signal answered passes to vehicle air bag electric-control system, realizes the pressure transducer functionality of sensor；Work as sensorWhen having heating voltage between harness II and sensor harness III, realize the heating cushion function of sensor (as described in epimere)；Work as biographyWhen having voltage between sensor harness I and sensor harness III, sensor harness I does not have to sensor harness II when without occupantCircuit is not connected to, and sensor does not heat；When there is passenger riding, it is logical that sensor harness I to sensor harness II is communicated with electric currentIt crosses, sensor harness II is heated for III sections to sensor harness.Occupant leaves seat, sensor harness II to pickup wireIII sections of beam stops heating, realizes intelligentized control method heating function.It can additionally be starched using temperature-sensitive carbon, such as PTC carbon slurry,Suitable thermo-sensitive material is added in carbon slurry, heater circuit is disconnected automatically to control heating temperature when carbon slurry being made to reach specific temperature,It prevents sensor from being damaged since temperature is excessively high, and then achievees the purpose that automatically control heating temperature.
But the main starting point of similar cushion (including back cushion) is still to meet based on the contour structures of human factor engineering, firstWhat is ensured is the reliable connection of people-pad-supporter, accelerates sanguimotor mode that can't effectively be tied with human physiological functionsIt closes, when keeping continuing sitting state, physiotheraping effect is limited.
