AI Technical Summary

Technical Problem

Existing car windshield sunshades require manual holding to secure them after being pulled out, and their automatic retraction and frequent use are inconvenient, failing to effectively prevent the interior temperature from rising due to high summer temperatures.

Method used

A car windshield sunshade device has been designed, including a retractor, a guide rail, a slider, and a limiting component. The slider is positioned at the upper limit of the guide rail, and the sunshade cloth is fixed by locking it with the guide rail through the limiting component. Combined with a roller blind cloth made of reflective and cooling materials, it provides two sunshade states and automatically adjusts the sunshade effect.

Benefits of technology

It achieves automatic fixing and stable sliding of the sunshade device, avoiding direct sunlight from affecting the driver's vision and increasing the temperature inside the vehicle. It eliminates the need for frequent operation, improving ease of use and safety.
