Abstract

The invention provides an ultrasonic sensor for a motor vehicle. The ultrasonic sensor comprises a metal film for sending and / or receiving an ultrasonic wave and a housing for at least supporting themetal film. The housing includes at least one discharging assembly including a discharging unit; the discharging unit is configured to keep the pressure intensity inside the housing to be consistent with that outside the housing so as to prevent entrance of impurities into the housing.

Description

technical field [0001] The invention relates to an ultrasonic sensor for a motor vehicle and a motor vehicle comprising the ultrasonic sensor. Background technique [0002] Recently, the demand for ultrasonic sensors has been increasing day by day. Ultrasonic sensors can be installed in various motor vehicles, for example, for short-distance detection. [0003] On a traditional ultrasonic sensor housing, it is necessary to potting glue and sealing, for example, by filling a sealant, in order to realize the waterproof function. This will increase the complexity of the process and increase the overall weight of the ultrasonic sensor. [0004] In addition, in a conventional ultrasonic sensor, mist and / or moisture will be generated inside the housing due to the temperature difference between the inside and outside of the housing, which may affect the performance of the ultrasonic sensor. Contents of the invention [0005] In view of the above problems, in the present invent...
