ULTRASONIC WAVE SENSOR FIXING STRUCTURE FOR REDUCING SIGNAL NOISE RATIO BY CONTROLLING A SURFACE WAVE AND AN ULTRASONIC SENSOR MOUNTING PLATFORM USING THE SAME

摘要

PURPOSE: An ultrasonic wave sensor fixing structure and an ultrasonic sensor mounting platform using the same are provided to reduce a surface wave by making a trap structure so that interference acoustically is generated in the surface between a receive sensor transferring an ultrasonic wave and a transmission sensor, thereby reducing single noise ratio.;CONSTITUTION: An ultrasonic sensor comprises a receive sensor transferring an ultrasonic wave and a transmission sensor. A sensor mounting hole in order to be exposed the ultrasonic sensor to outside is formed in a platform main body(110). A trap is formed in the exterior of the platform main body and controls a surface wave generating between the receive sensor and transmission sensor.;COPYRIGHT KIPO 2011
