AI Technical Summary
Traditional capacitive touchscreens are prone to freezing and frost in cold environments, leading to touch malfunctions. Existing heating solutions suffer from uneven heat distribution and heat accumulation, lacking a dynamic balancing mechanism, which affects device reliability and user experience.
An adjustable antifreeze component is installed inside the protective shell, which includes a heating plate with built-in heating wire and adjustable heat dissipation holes. The adjustment mechanism driven by springs and screws achieves directional heating and heat dissipation balance, and the silicone insert and anti-slip pads improve operational stability.
It achieves rapid and uniform heating and antifreeze of capacitive touch screens at low temperatures, avoids overheating and aging, improves device reliability and user experience, and has flexible heat dissipation adjustment capabilities.
