AI Technical Summary

Technical Problem

The existing opening and closing mechanism uses gear transmission, which results in a large product size and slow closing speed, affecting safety and reliability, and making it difficult to replace the old product.

Method used

The electromagnetic direct drive method is adopted. The trip coil and short-circuit induction coil are arranged horizontally and share key components to drive the moving iron core assembly to drive the push rod to achieve rapid closing or opening, which simplifies the structure and reduces the types and number of parts.

Benefits of technology

It achieves a compact structure, fast operation speed, strong breaking capacity, reduced costs, easy replacement of old products, and improved safety and reliability.
