This application claims priority to Chinese Patent Application No. 202420716242.X, filed with the China National Intellectual Property Administration on April 08, 2024 and entitled "FRONT FORK STRUCTURE WITH SHOCK ABSORPTION CHARACTERISTICS AND VEHICLE", which is hereby incorporated by reference in its entirety. TECHNICAL FIELD The present application relates to a field of cycling transportation technologies and, in particular, to a vehicle. BACKGROUND In recent years, with the continuous development of technology and the continuous improvement of people's living standards, the development of China's vehicle industry has been relatively rapid, and the future development trend of the vehicle industry remains the core industry for development. The functionality of vehicles is becoming increasingly high, and people's means of transportation are also becoming more diverse. Where a scooter, as a cycling tool, is highly favored by consumers due to its advantages such as fast folding speed, small size, easy portability and the ability to navigate through relatively crowded roads. Generally speaking, the scooter can include structures such as a frame, a front wheel, and a front fork, and the frame connected to the front wheel through the front fork. The scooter is prone to jolting when passing through uneven roads, which can affect safe driving and comfort. However, most of scooters at present do not have shock absorption structures, resulting in a poor riding experience when riding a scooter on bumpy roads. In addition, some models with shock absorption structure mainly use springs to achieve shock absorption, which generally have two obvious problems: firstly, the spring shock absorption is usually set on two sides of the front fork, making the overall aesthetics of the scooter insufficient; secondly, when the spring shock absorption passes through bumpy roads, the characteristics of the spring itself cause significant abnormal noise in the scooter, affecting the riding experience.
