The protective frame is typically a metal or high-strength plastic border installed over or around the original dashboard frame.
Functions:
Core Impact Protection: This is the primary function. During accidental vehicle rollovers or crashes, the metal frame makes initial contact with the ground, absorbing most of the impact force. This effectively prevents dashboard shell fractures, screen shattering, or internal structural damage. Repairing a dashboard costs significantly more than replacing a protective frame.
Impact Force Dispersion: By distributing point-impact forces across the entire frame structure, it reduces pressure on the dashboard mounting points, preventing the handlebar mounting base from fracturing due to impact.
