AI Technical Summary

Technical Problem

Existing charging cable storage devices use a synchronous bidirectional winding structure, which leads to cable tangling and jamming, makes it impossible to adjust the cable length independently, limits the flexibility of use, and makes the device bulky and difficult to carry.

Method used

The design incorporates an asynchronous bidirectional charging cable storage device with dual independent winding assemblies. The interior of the housing is divided into two storage compartments by a separator, with the charging cable and power cable placed in separate compartments. Asynchronous independent stretching is achieved through a rotating electrical connection assembly. A longitudinal stacked structure and rib ring separation design are used to reduce the device's volume.

Benefits of technology

It enables asynchronous and independent stretching of the charging cable and power cord, avoiding cable pulling interference, improving the flexibility of use, and the device has a compact structure, takes up little space, and is easy to carry.
