AI Technical Summary
In existing technologies, optical sensors are easily affected by dirt and freezing moisture, which can cause the rotating protective housing to become stuck. Furthermore, de-icing methods are inefficient or cannot detect the presence of frost in a timely manner, affecting the normal operation of the vehicle.
It employs a protective device that includes heat transfer enhancement elements, improves heat conduction through a combination of thermally conductive materials and heating elements, cleans the optical window using centrifugal effect, and rapidly de-ices through alternating rotation and optical detection.
It enables efficient and rapid de-icing and cleaning, prevents diagnostic errors, and ensures the normal operation of optical sensors.
