Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle equipment technology, specifically a camera housing for new energy vehicles. Background Technology

[0002] The housing of cameras in new energy vehicles serves as a core protective component of autonomous driving perception systems. As new energy vehicles rapidly iterate towards higher levels of autonomous driving, onboard cameras, acting as the "visual nerves" of environmental perception, undertake critical tasks such as road sign recognition, obstacle detection, and driver monitoring. Their performance and stability are directly related to driving safety.

[0003] Electromagnetic interference is a particularly prominent issue in new energy vehicle scenarios. On the one hand, components such as the on-board high-voltage battery system, motor controller, and DC / DC converter generate broadband electromagnetic noise during operation, which may couple to the camera circuitry through housing gaps or connection ports. On the other hand, if the camera's own high-frequency signal transmission is not effectively shielded, it can easily become an internal interference source, leading to increased image noise, dynamic range compression, and even system misjudgment. To address these issues, this invention provides a new energy vehicle camera housing to solve the aforementioned problems. Utility Model Content
