AI Technical Summary
The structural strength at the connection between the towing device and the longitudinal beam of the vehicle body is low, which makes the connecting bolts easy to break when towing a trailer with a large tonnage, affecting the safety of the towing device.
A box-shaped connector is installed at the connection between the towing device and the longitudinal beam of the vehicle body. It is connected to the rear assembly through a mounting plate and to the longitudinal beam of the vehicle body through an extension plate. This disperses the pulling force on the towing hook and increases the structural strength and durability of the connector.
This effectively reduces the risk of bolts breaking, ensures the safety and reliability of the towing device during use, and improves the stability and durability of the connection.
