Embodiment Construction

[0025] figure 1 The environment sensor device 1 according to a first preferred embodiment of the invention is shown in a side cross section. The environment sensor device 1 comprises an ultrasonic transducer 11 and a membrane 12 , wherein the ultrasonic transducer 11 is basically formed in this order from the connection of a front body 111 , a piezoelectric transducer element 112 and a rear body 113 . A coupling element 114 in the form of a plastic disk is arranged between converter element 112 and precursor body 111 . In this embodiment, the converter element 112 , the rear body 113 and the coupling element 114 are annular elements with a circular outer diameter and a circular recess in the center. In this case, the contacting of the piezoelectric transducer element 112 is achieved by arranging the first pole on a first side of the transducer element 112 and by arranging the second pole on the side opposite the first side, wherein this The two poles are connected to the co...

Abstract

The present invention discloses a surroundings-sensing system for transmitting and / or receiving ultrasound signals, said system comprising an ultrasonic transducer having at least one transducer element and at least one resonance body that has a front body and a rear body, and comprising a membrane for sound transmission, said membrane being coupled to an end face of the front body. The front body, the transducer element and the rear body are separably connected to each other, and the front body is secured to the membrane. Furthermore, the present invention discloses a motor vehicle having a bumper, side mirror or door section and at least one surroundings-sensing system of this type, the membrane of the surroundings-sensing system being formed by an outer shell of the bumper, the side mirror or the door section, and the ultrasonic transducer being hidden behind the outer shell.

Description

technical field [0001] The invention relates to an environment sensor device for ultrasonic-based environment sensing using an acoustic wave transducer, for example in addition to motor vehicles and moving or stationary machines (e.g. robots, agricultural machinery or construction machinery) and thus is used, for example, as a typical application of an environment detection aid for a corresponding parking assistance system, and also for measuring the distance to a specific object. Furthermore, the invention relates to a motor vehicle, wherein at least one of the ambient sensor devices is arranged on a bumper, a side mirror or a door section of the motor vehicle. Background technique [0002] Ultrasonic-based environmental sensors are currently used in motor vehicles in this technical field, in which piezoelectric-based acoustic transducers are generally used. In this case, the ultrasonic signal is usually transmitted from the transmitter to the receiver or from the transmit...
