AI Technical Summary

Technical Problem

The existing tailgate power unit has problems with maintenance convenience and sealing performance. These include welding of the oil reservoir, which makes changing hydraulic oil complicated and difficult to clean; oil pipe joints and cables passing through gaps, which reduces the sealing effect; and the oil tank cover not being fixed firmly, which leads to insufficient sealing. In particular, it is easy to damage electronic components and hydraulic system in harsh environments.

Method used

The oil can body and oil source tank are designed with a sliding connection. The transparent plastic oil can is easy to clean. The waterproof cable sheath ensures the cable is sealed. The clamp-type partition straight connector and sealing rubber gasket improve the sealing performance. The oil tank cover is equipped with buckles and sealing strips to ensure long-term sealing.

Benefits of technology

It simplifies hydraulic oil replacement, prevents dust and moisture intrusion, protects electronic components, improves sealing performance and device reliability, and adapts to long-term use in harsh environments.
