AI Technical Summary

Technical Problem

During the unloading process of an existing freight vehicle, when the tail bumper is automatically converted to the storage state, the detection system may not be able to detect the storage state of bumper, resulting in the unloading operation failure.

Method used

A loading and unloading device is designed, including bumper devices. The bumper devices can be converted into driving position and storage position through electric mode, and are controlled by automatic unloading switches and bumper switches. In the automatic priority state, the automatic unloading switch is preferred. The bumper device can only be operated by the bumper switch under certain conditions to ensure that the bumper is in the correct position.

Benefits of technology

The automatic storage and uninstallation operations of bumper are realized to ensure safety and efficiency during the uninstallation process and avoid uninstallation operation interruptions caused by bumper detection failure.
