Automotive rearview mirrors (primarily optical types, both interior and exterior) generally consist of a mirror element (glass), a housing (casing), a support/adjustment mechanism (including motors or manual linkages), a heating element (on some models), and a mounting base; electric exterior mirrors also integrate components such as turn signals, folding motors, and wiring harnesses.
1. Mirror element: Interior mirrors are typically flat (or wedge-shaped anti-glare) mirrors, while exterior mirrors are usually convex (or dual-curvature) mirrors; the surface is coated with aluminum, silver, or chrome to provide reflectivity.
2. Mirror housing/casing: A plastic or metal shell that provides protection, styling, and aerodynamic optimization.
3. Adjustment mechanism: Manual operation via cables or levers; electric versions include adjustment motors (for up/down and left/right movement) and folding motors (for exterior mirrors).
4. Heating element: A heating coil embedded in the back of the mirror glass, used for defrosting and defogging.
5. Mounting base: Attaches to the vehicle door (exterior) or windshield (interior); includes the bracket, pivot pin, etc.
6. Additional functional components (common in exterior mirrors): Turn signal lights, blind-spot monitoring sensors, wiring harnesses, and gaskets.
