Disclosed is an ultrasonic sensor device for a vehicle. An ultrasonic sensor has a pot-shaped diaphragm including a diaphragm base for emitting/receiving ultrasonic signals and a decoupling ring with a ring portion having a hollow cylinder shape and at least portions of the inner peripheral wall which abut an outer lateral diaphragm surface. The diaphragm is inserted, with the decoupling ring, at least in portions into a recess in a covering part of the vehicle. A preloading element, at least partially extending around the ring portion, is located at the axial end of the ring portion remote from the diaphragm base. The preloading element extends from the axial end in an axial direction towards the diaphragm base and extends radially outwardly. Also disclosed is an ultrasonic sensor assembly for a vehicle having a covering part, and an ultrasonic sensor device inserted into a recess in the covering part.
An ultrasonic sensor device for a motor vehicle, comprising an ultrasonic sensor which has a pot-shaped diaphragm having a diaphragm base for at least one of emitting and/or receiving ultrasonic signals and having a decoupling ring which comprises a ring portion that has a shape of a hollow cylinder and at least portions of the inner peripheral wall which abut an outer lateral surface of the diaphragm, wherein the diaphragm is inserted, together with the decoupling ring, at least in portions into a recess in a covering part of the motor vehicle, wherein a preloading element which at least partially extends around the ring portion is located at an axial end of the ring portion, which axial end is remote from the diaphragm base, which preloading element extends from the axial end in an axial direction towards the diaphragm base and extends outwards in a radial direction.
