AI Technical Summary

Technical Problem

Existing head-mounted display devices use a gear and rack structure for interpupillary distance adjustment, which results in high friction, poor stability, and noise during adjustment, affecting the user experience.

Method used

A magnetic adjustment mechanism is used to drive the movement of the lens module. Combined with the human eye detection module and control unit, stepless silent adjustment is achieved. The first magnetic adjustment mechanism drives the lens module to move towards each other, and the second magnetic adjustment mechanism drives the lens module to move away from each other. The interpupillary distance is adjusted by using the repulsive force provided by the electromagnet.

Benefits of technology

It achieves stable and noiseless interpupillary distance adjustment, improving the user's wearing experience.
