Ultrasonic sensor arrangement for a motor vehicle with elements for reducing the propagation of bending waves and associated production method

摘要

The invention relates to an ultrasonic sensor arrangement (11) for a motor vehicle (1) with a vehicle component (10) and with an ultrasonic sensor (4) which is connected to the vehicle component (10), wherein the ultrasonic sensor (4) is designed to Transmitting ultrasonic signal through the vehicle component (10) and / or receiving an ultrasonic signal through the vehicle component (10), and wherein the vehicle component (10) comprises a plurality of elements (16) for reducing propagation of structure-borne noise in the vehicle component (10) A sequence of emitting the ultrasonic signal and / or receiving the ultrasonic signal, wherein the plurality of elements (16) is adapted to reflect the propagating in the vehicle component (10) structure-borne sound such that the propagation of structure-borne noise is reduced by a destructive interference ,
