Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a scooter with a double-bar stable folding structure. Background Technology

[0002] Electric scooters, as a new type of short-distance transportation tool, are increasingly popular due to their small size and ease of operation. Electric scooters typically include a control stick, a front wheel, foot pedals, and a rear wheel. The rear wheel and the rear end of the foot pedals are connected. The upper end of the control stick forms the front of the scooter, and the lower end of the control stick is indirectly connected to the front wheel. The control stick is also indirectly connected to the front end of the foot pedals.

[0003] Electric scooters on the market were initially designed for portability and lightness, with relatively simple designs, so most used a single-stick control. However, as the practical applications of electric scooters have gradually increased, single-stick control cannot meet the needs of high-strength and stable usage scenarios. To solve this problem, dual-stick control has emerged on the market, which can effectively improve the stability of vehicle handling and the strength of the stick. Existing dual-stick electric scooters use a single-buckle folding structure to improve storage capacity. However, using a single-buckle structure to fix the high strength of the dual-stick control can easily lead to loosening after long-term use, affecting the control experience and failing to meet user needs.
