Išradimo trūkumas yra tas, kad įrenginio konstrukcija yra gana sudėtinga, reikalaujanti didelio gamybos ir surinkimo tikslumo, slydimo kontaktai ir sandarinimas neužtikrina patikimos bei ilgalaikės įrenginio eksploatacijosThe disadvantage of the invention is that the construction of the device is quite complicated, requiring high manufacturing and assembly precision, sliding contacts and sealing do not ensure reliable and long-term operation of the device.

Šio išradimo tikslas - supaprastinti įrenginio konstrukciją padidinti eksploatavimo laikąThe object of the present invention is to simplify the design of the device to increase its service life

Išradimo tikslas pasiekiamas tuo, kad įrenginio, skirto informacijai perduoti taktiliniu būdu pavaroje, susidedančioje iš korpuso, dviejų elektrodų, strypo su taktiline galvute ir dangtelio, papildomai įvesta dvi tamprios membranos , kur viena iš . jų pritvirtinta tarp strypo ir taktilinės galvutės, o kita strypo apatinėje dalyje ir dalija korpuso vidinę ertmę į dvi dalis, kur viena iš jų pripildyta valdomo klampumo skysčio, o elektrodai pagaminti cilindro formos, laisvai užmauti ant strypo ir nejudamai pritvirtinti prie korpuso per papildomai įvestą laikiklį.The object of the invention is achieved by the addition of two elastic membranes, one of which is provided in a device for tactically transmitting information in a gear consisting of a housing, two electrodes, a rod with a tactile head and a cap. mounted between the rod and the tactile head, and the other at the bottom of the rod, dividing the inner cavity of the housing into two parts, one filled with a controlled viscosity fluid and electrodes made in cylindrical form, freely pressed on the rod and fixedly fixed to the housing .

Išradimo esmė paaiškinta brėžinyje.The invention is explained in the drawing.

brėžinyje pavaizduota įrenginio, skirto informacijai perduoti taktiliniu būdu, pavaros skersinis pjūvis.Figure 1 is a cross-sectional view of a drive for a tactile transmission device.

Įrenginio, skirto informacijai perduoti taktiliniu būdu pavara susideda iš korpuso 1, dviejų cilindro formos elektrodų 2, strypo 3 su taktiline galvute 4, dangtelio 5, dviejų tamprių membranų 6 ir 7, kur viena iš jų pritvirtinta tarp strypo 3 ir taktilinės galvutės 4, o kita - strypo 3 apatinėje dalyje ir dalija korpuso 1 vidinę ertmę į dvi dalis 8 ir 9, kur viena iš jų pripildyta valdomo klampumo skysčio, o cilindro formos elektrodai 2 laisvai užmauti ant strypo 3 ir nejudamai pritvirtinti prie korpuso 1 per papildomai įvestą laikiklį 10.The actuator for transmitting information tactically comprises a housing 1, two cylindrical electrodes 2, a rod 3 with a tactile head 4, a cap 5, two elastic membranes 6 and 7, one of which is mounted between the rod 3 and the tactile head 4, and the other in the lower part of the rod 3 and dividing the inner cavity of the housing 1 into two portions 8 and 9, one filled with fluid of controlled viscosity, the cylindrical electrodes 2 being loosely applied to the rod 3 and fixedly attached to the housing 1 via an additional insert.

Įrenginio informacijai perduoti taktiliniu būdu pavara veikia sekančiai.The actuator operates as follows for tactile transmission of device information.

Korpuso 1 ertmėje 8 sukuriamas reikiamo dydžio slėgis, kuris veikia tamprią membraną 6. Membrana 6, priklausomai nuo slėgio ženklo, tampriai deformuojama aukštyn arba žemyn. Dėl tamprios membranos 6 deformacijos juda prie jos pritvirtintas strypas 3 su taktiline galvute 4, ant kurio laisvai užmauti du cilindro formos elektrodai 2 ir nejudamai pritvirtinti prie korpuso 1 per laikiklį 10. Korpuso 1 ertmė 9 yra pripildyta valdomo klampumo skysčio. Prie cilindro formos elektrodų 2 prijungus reikiamo didumo elektros įtampą susidaro elektros laukas, dėl kurio, tarpuose tarp elektrodų 2 ir strypo 3 esančio skysčio klampumas padidėja ir užfiksuoja strypą 3 su taktiline galvute 4 norimoje padėtyje be tiesioginio kontakto su elektrodais 2. Taip užfiksuojant, išvengiama papildomos trinties ir deformacijų elektros perdavimo grandinėje, o tai leidžia padidinti įrenginio eksploatacijos laiką ir supaprastina konstrukciją. Strypas 3 su taktiline galvute 4 išlieka toje padėtyje tol, kol neišjungiama įtampa cilindro formos elektrodams 2. Nepriklausomai nuo to ar tampri membrana 6 deformuojama toliau ar ne, strypas 3 išlieka nejudamoje padėtyje ir atlieka informacijos perdavimo funkciją. Išjungus įtampą cilindro formos elektrodams 2, tamprios membranos 6 ir 7, kurios taip pat atlieka ir skysčio ' sandarinimo funkciją gražina strypą 3 su taktiline galvute 4 į pradinę padėtį. Tokiu būdu strypo 3 su taktiline galvute 4 judesį galima valdyti taip, kad aklasis ar silpnaregis žmogus, pirštu liesdamas dangtelio 5 paviršių, gali pajusti ar taktiline galvutė 4 išlindus virš dangtelio 5 plokštumos ar ne ir taip nuskaityti perduodamą informaciją.The cavity 8 of the housing 1 generates a pressure of the required size which acts on the resilient membrane 6. The diaphragm 6 is elastically deformed up or down, depending on the pressure mark. Due to the elastic deformation of the diaphragm 6, a rod 3 with a tactical head 4 attached thereto is moved, on which two cylindrical electrodes 2 are loosely inserted and fixed fixedly to the housing 1 through a holder 10. The cavity 9 of the housing 1 is filled Applying a sufficient amount of voltage to the cylindrical electrodes 2 creates an electric field that increases the viscosity of the fluid between the electrodes 2 and the rod 3 and locks the rod 3 with the tactile head 4 in the desired position without direct contact with the electrodes 2. friction and deformation in the electrical transmission circuit, which increases the life of the unit and simplifies construction. The rod 3 with the tactile head 4 remains in that position until the voltage is applied to the cylindrical electrodes 2. Regardless of whether the resilient membrane 6 is further deformed or not, the rod 3 remains in a stationary position and functions as an information transmitter. When the cylindrical electrodes 2 are disconnected, the resilient membranes 6 and 7, which also perform a fluid sealing function, return the rod 3 with the tactile head 4 to its original position. In this way, the movement of the bar 3 with tactile head 4 can be controlled such that a blind or partially sighted person may feel the tactile head 4 touching the plane 5 of the lid 5 or not and thus read the transmitted information.

Palyginus su prototipu, nauja konstruktyvinių elementų visuma, padeda valdyti visus judančius informacijos nešiklius vienu varikliu, panaikina trintį ir deformacijas elektros perdavimo grandinėje, o visa tai leidžia supaprastinti įrenginio konstrukciją ir tuo pačiu padidinti eksploatavimo laiką.Compared to the prototype, the new set of structural elements helps to control all moving media on a single motor, eliminates friction and deformation in the electrical transmission circuit, all of which simplifies the design of the unit while increasing its service life.
