Ultrasound sensor
First Claim
1. An ultrasound sensor, comprising:
- a housing which is fixedly arranged at inner side of a periphery member of a vehicle;
an ultrasound vibrator for sending and receiving ultrasound, the ultrasound vibrator being accommodated in the housing and fixed to an end portion of the housing, the end portion facing the periphery member; and
an ultrasound transferring member which is arranged at the end portion of the housing and contacts both the ultrasound vibrator and the periphery member of the vehicle, whereinthe ultrasound transferring member is constructed of a different material from that of the housing to have an acoustic impedance with a medium value between an acoustic impedance of the ultrasound vibrator and that of the periphery member, the ultrasound being sent and received through the ultrasound transferring member and the periphery member of the vehicle.

Abstract
An ultrasound sensor for a vehicle has a housing which is fixedly arranged at a vehicle inner side of a periphery member of the vehicle, an ultrasound vibrator for sending and receiving ultrasound, and an ultrasound transferring member which is constructed of a different material from that of the housing to have an acoustic impedance with a medium value between an acoustic impedance of the ultrasound vibrator and that of the periphery member. The ultrasound vibrator is accommodated in the housing and fixed to an end portion of the housing, which faces the periphery member. The ultrasound transferring member is arranged at the end portion of the housing, and contacts both the ultrasound vibrator and the periphery member of the vehicle.

8. An ultrasound sensor, comprising:
-
a housing which is fixed to a side of a base; an ultrasound vibrator for sending ultrasound to an opposite side of the base and for receiving ultrasound from the opposite side, the ultrasound vibrator being accommodated in the housing and fixed to an inner surface of an end portion of the housing with a vibration direction of the ultrasound vibrator being substantially perpendicular to the inner surface, the end portion of the housing facing the base; and an ultrasound transferring member which is arranged at the end portion of the housing and contacts both the ultrasound vibrator and the base, wherein the ultrasound transferring member is constructed of a different material from that of the housing to have an acoustic impedance with a predetermined value. - View Dependent Claims (9, 10, 11, 12, 13)
