AI Technical Summary

Technical Problem

In existing technologies, when there is an angle between the axis of the charging head and the guide surface, it is easy to get stuck, resulting in poor docking during the charging process. In addition, the overall length of the charging rod and the vehicle-end power receiving device is too long, which is cumbersome. Furthermore, the grounding plug and socket are prone to getting stuck or failing to dock due to coaxial errors.

Method used

The design employs a columnar connector and guide seat, including floating guide components and a flexible mechanism. The guide surface inside the guide seat has been changed from rigid to flexible. The charging rod and the protective sleeve adopt a rolling fit. The guide seat is equipped with a multi-conical groove structure and a floating socket to ensure smooth docking between the charging rod and the vehicle-end power receiving device.

Benefits of technology

The problem of jamming between the charging head and the guide surface has been solved, the overall length of the charging device has been shortened, the reliability and smoothness of the docking have been improved, the risk of wear and jamming has been reduced, and the successful completion of automatic charging has been ensured.
