[0002] Electric vehicles, also known as battery-powered vehicles, are pure electric motor vehicles powered by batteries and driven by electric motors in DC, AC, series, and separately excited modes. In recent years, they have become very popular in my country. Domestically, battery-powered vehicles are mainly used for sightseeing, passenger transport, security patrols, and cargo handling. Electric sightseeing vehicles are mainly used for passenger transport in parks, scenic spots, resorts, universities, hospitals, golf courses, real estate companies, and other places. Electric patrol vehicles are mainly used for security patrols in station squares and densely populated areas. Electric transport vehicles are mainly used in factories, ports, docks, and logistics warehouses.

[0003] Electric vehicles, as a green and low-carbon mode of transportation, have gained increasing popularity among consumers. The front fork of an electric vehicle is one of the key components, supporting not only the front wheel but also serving important functions such as steering and shock absorption. However, its shock absorption is poor under complex road conditions, failing to effectively absorb high-frequency impacts, resulting in poor vehicle stability and reduced rider comfort. To address these issues, we propose a damping shock absorption structure for the front fork of an electric vehicle. Utility Model Content

[0022] As a technical optimization of this utility model, a reinforcing ring 4 is fixedly connected to the upper surface of the front fork bracket 1, and the inner ring of the reinforcing ring 4 is fixedly connected to the outer surface of the positioning rod 3.

[0023] In this embodiment, the reinforcing ring 4 facilitates the reinforcement of the positioning rod 3, thereby enhancing the stability of the positioning rod 3.
