System and method for directing an airflow into a sensor enclosure
摘要
說明書
The cover 462 may be made from any suitable material that allows the one or more sensors of the enclosure 400 to properly function while shielding the one or more sensors from environmental elements (e.g., rain, snow, moisture, wind, dust, radiation, oxidation, etc.). Further, the suitable material must be transparent to wavelengths of light or electro-magnetic waves receptive to the LiDAR sensor 430 and the plurality of cameras 432. For example, for the LiDAR sensor 430 to properly operate, the cover 462 must allow laser pulses emitted from the LiDAR sensor 430 to pass through the cover 462 to reach a target and then reflect back through the cover 462 and back to the LiDAR sensor 430. Similarly, for the plurality of cameras 432 to properly operate, the cover 462 must allow visible light to enter. In addition to being transparent to wavelengths of light, the suitable material must also be able to withstand potential impacts from roadside debris without causing damages to the LiDAR sensor 430 or the plurality of cameras 432. In an implementation, the cover 462 can be made of acrylic glass (e.g., Cylux, Plexiglas, Acrylite, Lucite, Perspex, etc.). In another implementation, the cover 462 can be made of strengthen glass (e.g., Coring? Gorilla? glass). In yet another implementation, the cover 362 can be made of laminated safety glass held in place by layers of polyvinyl butyral (PVB), ethylene-vinyl acetate (EVA), or other similar chemical compounds. Many implementations are possible and contemplated.
