Description

Technical Field

[0001] This utility model relates to an electric handling vehicle for logistics. Background Technology

[0002] In existing electric transport vehicles, a return device needs to be installed between the handle and the frame. The handle is equipped with a gyroscope or angle switch. If the handle cannot return to its normal position, it will affect the normal operation of the equipment.

[0003] Currently, the main return mechanism used is a gas spring. However, gas springs are affected by temperature. In hot weather, the operating force of the handlebar is adjusted based on ergonomic principles to match the gas spring pressure (elasticity). In winter, the gas spring pressure (elasticity) decreases, causing the handlebar to fail to return to its original position. Conversely, in hot weather, the operating force feels too great, resulting in poor comfort. Installing the gas spring between the handlebar and the frame requires special tools, making the process quite cumbersome. Utility Model Content
