Description

Technical Field

[0001] The present invention relates to the technical field of welding workbenches, and particularly to a welding workbench for the rear hanger of an electric vehicle. Background Art

[0002] An electric vehicle, also known as an electric bicycle or an electric two-wheeler (broadly including electric motorcycles, etc.), is a two-wheeled (or in some cases three-wheeled) vehicle powered by electricity. The rear hanger of an electric vehicle is a metal or plastic structure installed at the rear of the electric vehicle for carrying items. It can hold daily items such as backpacks, shopping bags, and helmets, making it convenient for riders to carry. Some rear hangers are designed with mounting holes for installing accessories such as tail boxes and baby seats, increasing the practicality and functionality of the vehicle. The structure is simple and mainly serves the basic function of carrying goods. In the electric vehicle manufacturing industry, as an important load-bearing and decorative component, the production quality and efficiency of the rear hanger of an electric vehicle are directly related to the overall performance and market competitiveness of the electric vehicle. The traditional welding method for the rear hanger of an electric vehicle mainly relies on manual operation. Workers need to hold welding equipment and weld each component of the rear hanger one by one at a fixed work station. However, manual welding is slow and greatly affected by the proficiency and fatigue of the workers. The harmful factors such as arc light, soot, and high temperature generated during the welding process pose a threat to the physical health of the workers. Summary of the Invention
