AI Technical Summary

Technical Problem

Existing helmet adjustment mechanisms rely on manual rotation, which is cumbersome, inefficient, and lacks an automatic retraction or reset mechanism. This makes it impossible to meet the needs for quick wearing and immediate adjustment, and it is also difficult to integrate a power mechanism within a limited space.

Method used

The device employs a combination of a spring and a transmission gear. The spring stores energy under external force and automatically releases it to drive the transmission gear to rotate, thereby automatically adjusting the tension of the headband. Combined with a guide plate and a snap-fit ​​structure, it ensures that the headband extends and retracts synchronously and fits evenly.

Benefits of technology

It achieves automatic tension adjustment and reset of the helmet head lock, improving wearing comfort and stability, reducing operation steps, and enhancing structural protection and transmission smoothness.
