Abstract

ESTA INVENCION SE REFIERE A UN SENSOR AL IMPACTO QUE NO TIENE CONTACTOS ELECTRICOS EXPUESTOS AL AIRE Y NINGUNA PIEZA MOVIL, CON ALTA DURABILIDAD Y PRESTACION, Y QUE PUEDE DETECTAR EL CHOQUE DE UN VEHICULO ESTANDO INCLUSO MONTADO EN SU INTERIOR. EL SENSOR DE IMPACTO CONSTA DE UN ELEMENTO PIEZOELECTRICO (3, 13) QUE, CUANDO SE COMPRIME, GENERA UN VOLTAJE PROPORCIONAL A LA FUERZA DE COMPRESION, UN PAR DE ELECTRODOS (1C, 1D, 11C, 14) INTERCALADOS EN EL ELEMENTO PIEZOELECTRICO, UN ELEMENTO DE INERCIA (6, 16) PARA APLICAR LA FUERZA DE COMPRESION A UNO DE LOS ELECTRODOS Y UN ELEMENTO PUENTE (7, 17) PARA PUENTEAR EL ELEMENTO DE INERCIA (6, 16) HACIA EL ELEMENTO PIEZOELECTRICO. CUANDO SE LE APLICA UNA FUERZA IMPACTANTE AL ELEMENTO DE INERCIA (6, 16), EL ELEMENTO DE INERCIA (3, 13) COMPRIME AL ELEMENTO DE PIEZOELECTRICO (3, 13) CON LA FUERZA DE COMPRESION PROPORCIONAL A LA FUERZA IMPACTANTE Y EL ELEMENTO PIEZOELECTRICO (3, 13) GENERA EL VOLTAJE CORRESPONDIENTE A LA FUERZA DE COMPRESION.
