AI Technical Summary
Traditional plastic-based car roofs are prone to deformation and are difficult to restore to their original shape when subjected to excessive pressure, leading to damage.
The canopy components, which are made by injection molding, are combined with a canopy reinforcement mechanism. This mechanism includes stacked reinforcing main beams and secondary beams, clamps, beam frames, spring plates, and stabilizing plates. These components are assembled and fixed with adhesives to form a stable structure that can withstand pressure and quickly reset.
It improves the compressive strength of the ceiling, ensuring that it can quickly return to its original position after being subjected to pressure, preventing collapse and protecting the wiring from damage.
