Description
技术领域 Technical field

背景技术 Background technique
脚踏车是绿色环保的交通工具。常见的脚踏车有两轮脚踏车，两轮脚踏车是依靠骑车人的重心变化实现转向，要求重心、车速与车前轮的弯折角度的变化协调一致，否则容易失去平衡。常见的还有三轮车，三轮车无需考虑重心、车速与车前轮的弯折角度的变化是否协调一致。在需要转弯的时候，车速很小也能保持车的平衡，主要依靠车前轮的弯折实现转向。但是，当车速很快、转向角度大时，由于现有三轮车的整个车架是刚性的，骑车人的重心和车的重心变得难以保持协调，而容易使骑车人摔下或是三轮车发生侧翻，不能实现灵活地转向。
Bicycles are green vehicles. A common bicycle has a two-wheeled bicycle. The two-wheel bicycle relies on the change of the center of gravity of the rider to achieve steering. The center of gravity, the speed of the vehicle and the bending angle of the front wheel of the vehicle are coordinated, otherwise it is easy to lose balance. It is also common to have a tricycle. The tricycle does not need to consider whether the center of gravity, the speed of the vehicle and the bending angle of the front wheel are consistent. When a turn is needed, the speed of the car can be kept small, and the car is balanced by the bending of the front wheel. However, when the speed is fast and the steering angle is large, since the entire frame of the existing tricycle is rigid, the center of gravity of the rider and the center of gravity of the car become difficult to maintain coordination, and it is easy for the rider to fall or the tricycle A rollover occurs and a flexible turn is not possible.
