AI Technical Summary

Technical Problem

Existing battery swapping robots need to move four times during the battery swapping process for electric heavy trucks. The long path and time consumption limit the throughput capacity of battery swapping stations. Especially during peak traffic hours, queues are likely to form, which weakens the speed advantage of the battery swapping mode.

Method used

The battery lifting device adopts a double telescopic fork design combined with a slewing mechanism. The slewing mechanism allows one side of the telescopic fork to remove the depleted battery pack and then rotate it 180° in place, enabling direct installation of the fully charged battery pack. This eliminates the need for two separate movements to remove and store the battery. The battery pack is also limited by a clamp driven by an electric telescopic rod.

Benefits of technology

It shortens the time for a single battery swap operation, improves the overall operational efficiency of the battery swapping station, prevents the battery pack from slipping during movement or rotation, and increases the battery swapping speed and throughput.

Abstract

This utility model relates to the field of battery swapping station technology, specifically to a battery lifting device for battery swapping stations. It includes a crane main beam, on which a lifting trolley is mounted. A slewing mechanism is installed on the bottom surface of the lifting trolley. A mounting plate is fixedly connected to the bottom end of the slewing mechanism. A lifting mechanism and a guide column are mounted on the bottom surface of the mounting plate. A fork carriage is slidably connected to the guide column. A movable pulley is installed at the top of the fork carriage. Telescopic forks are installed on both sides of the bottom end of the fork carriage. An electric telescopic rod is fixedly connected to both sides of the fork carriage. Telescopic joints are slidably connected to both ends of the electric telescopic rods, and clamps are fixedly connected to the ends of the telescopic joints. This utility model, through the combination of a double telescopic fork design and a slewing mechanism, allows a fully charged battery pack to be installed on the other side after a depleted battery pack is removed by one side of the telescopic fork and rotated 180° in place by the slewing mechanism. This shortens the battery swapping operation time and improves the overall operating efficiency of the battery swapping station.
