AI Technical Summary

Technical Problem

In existing vehicle electronic device housing designs, water is prone to accumulating and coming into contact with rear components, leading to a high likelihood of corrosion and malfunction.

Method used

Design a housing for vehicle-mounted electronic devices, which adopts an inclined configuration with the front side lower than the rear side, combined with a groove and inclined surface structure. The front edge of the groove is located at the lower rear edge of the upper housing, and the bottom surface of the groove is inclined downward in the width direction of the vehicle to form a water flow channel to avoid water retention and contact.

Benefits of technology

It effectively prevents water from accumulating at the rear of the casing, reduces contact with rear components, lowers the risk of corrosion, and eliminates the need for additional components, resulting in a lightweight casing and improved space utilization efficiency.
