Title:
ULTRASONIC TRANSCEIVER
Document Type and Number:
WIPO Patent Application WO/2023/200003
Kind Code:
A1
Abstract:
A coating layer having an ultraviolet-resistant effect and impact resistance is provided on the surface of a resin film (8) to form a protective film, which is bonded to the surface of an ultrasonic sensor, thereby protecting the ultrasonic sensor from impacts caused by flying stones etc., without impairing the ultrasonic wave transmitting/receiving ability of the ultrasonic sensor. Further, by providing a hard coat layer (9) having an ultraviolet-resistant effect on the surface of the protective film, it is possible to prevent yellowing due to ultraviolet rays and also prevent deterioration of sensor characteristics due to peeling of the protective film. In addition, a colored layer (11) can be obtained by stacking a plurality of layers of ink that has been adjusted to the same color as the exterior parts of a vehicle, so that the design can be ensured.
