AI Technical Summary

Technical Problem

Existing power tools face problems such as excessive heat generation and vibration in the control module and motor during operation, leading to tool damage and a decline in the user experience.

Method used

A vibration damping mechanism is installed between the housings of the power tool, including a first vibration damping element and a second vibration damping element. The vibration transmission is reduced by a combination design of a damping ring and soft rubber coating. At the same time, the vibration deflection angle of the housing is optimized, and the heat dissipation effect is improved by a flow guiding mechanism.

Benefits of technology

It effectively reduces vibration transmission, improves user comfort and tool life, while also improving heat dissipation and enhancing overall tool performance.
