AI Technical Summary

Technical Problem

Existing electric vehicle electronic locks are difficult to guarantee production and transmission stability due to the influence of machining accuracy and dimensional chain errors. Furthermore, they have insufficient output force in extremely cold or freezing environments, and their transmission methods are limited, failing to meet diverse customer needs.

Method used

The shell design features a semi-enclosed structure with embedded pole plates and gear sets. Through a multi-stage gear transmission structure consisting of a worm gear, a transition wheel, and an output transition wheel, combined with a signal feedback mechanism using a sliding spring and a feedback spring, the microswitch is eliminated, achieving multi-stage gear transmission and flexible signal feedback.

Benefits of technology

The output force of the electronic lock has been increased, ensuring normal operation in harsh environments, adapting to different customers' conductivity methods and signal feedback requirements, and reducing the cost of structural adjustments and new mold openings.
