[0002] Electric scooters are a modern personal travel tool that combines traditional scooters with electric drive technology to provide a convenient, environmentally friendly and efficient short-distance transportation method. The folding structure of electric scooters is designed to facilitate carrying and storage. Its specific structure and design vary depending on the brand and model, but in general, the handlebars and pedals of electric scooters are usually equipped with folding joints, and safety locking devices are set on the folding joints to prevent accidental folding or unfolding, thereby increasing the safety of use. However, most electric scooters currently have only a single locking device on the folding joints, which is locked by a locking pin after the electric scooter is unfolded to prevent the handlebars from turning. However, in order to improve the safety of electric scooters, it is necessary to set up a folding structure with multiple safety protections, so that when one of the locking methods fails, other locking methods can continue to provide protection.
