Taking a manual anti-glare interior rearview mirror as an example, its primary structure is illustrated in the figure; typical sub-components include the mirror frame, mirror element assembly, mirror housing, adjustment lever, spherical cover, mirror arm, and mounting base.
The interior rearview mirror is primarily positioned in the area of the front windshield, providing the driver with a view of the area behind the vehicle. It is typically mounted by engaging the mirror's mounting base with a corresponding base attached to the windshield-using methods such as snap-ring connections or screw fastening.
Tip: For manual anti-glare interior rearview mirrors, the anti-glare function is activated by toggling the adjustment lever.
Field of View Compliance: Class II primary exterior mirrors must allow the driver to see a road width of ≥5000 mm at a distance of 30 m behind the eye point on both the driver and passenger sides, while also covering an area 4 m behind the eye point with a width of 1 m.
Aerodynamic Styling: The mirror housing and vehicle body form a diverging "V-shape" to reduce airflow impact; the connecting arm is kept as thin as possible to minimize turbulence; and a clearance of ≥40 mm is maintained between the housing and the base to reduce wind noise.
Positioning Requirements: The field of view must cover the target area under normal seating conditions; the mirror must be located within the side window's wiper sweep area; and the lateral protrusion must be ≤250 mm (when the lowest edge is ≤1800 mm from the ground at full load).
Safety Design: The exterior shape must avoid sharp protrusions to protect pedestrians and occupants during a collision, while also ensuring functional performance across various climatic conditions.
