a seat mounted on a chassis and including a rear support frame having two rear support legs and a first cross member extending left and right between upper ends of the two rear support legs, lower ends of the two rear support legs being pivotably connected to left and right sides of a rear end of the chassis, respectively, and a front support frame having two front support legs and a second cross member extending left and right between upper ends of the two front support legs, the two rear support legs and the two front support legs being pivotably cross-connected to each other at two crossing portions such that the rear support frame and the front support frame can pivot relative to each other to unfold and fold; a flexible cushion of the seat is mounted between the first cross beam and the second cross beam; wherein in a deployed state, the operating lever extends upwardly (e.g., directly or obliquely upwardly) from the chassis, the front and rear brackets are deployed relative to each other such that the seat cushion is deployed horizontally (or substantially in a horizontal plane), and a lower portion of the front bracket is supported on the chassis; in a folded state, the operating rod is pivoted to the upper surface of the chassis to a folded position, the front support frame and the rear support frame are folded with each other, and the seat is folded towards the upper surface of the chassis;
a control system including an angle sensing system and a speed adjustment mechanism connected to the front wheel.
Thus, when it is desired to use the seat in an unfolded state (in which the lower end of the rear support leg and the lower end of the front support leg are separated from each other and the first cross member at the upper end of the rear support leg and the second cross member at the upper end of the front support leg are separated from each other so that the flexible seat cushion installed between the first cross member and the second cross member is unfolded substantially horizontally), the user can sit on the seat cushion and operate the light electric scooter by means of the joystick in the unfolded state (extended upward); when not in use, the seat can be folded in a folded state (in which the front and rear support legs are pivotally folded toward each other through the intersection, at which time the lower ends of the rear support legs and the lower ends of the front support legs are folded toward each other and the first cross member and the second cross member are folded toward each other) and folded integrally onto the upper surface of the chassis, and the operating lever is also folded toward the upper surface of the chassis (for example, pivoted to a folded position), so that the entire lightweight electric scooter is folded for transportation or storage. It can be seen that excellent portability is achieved in a compact configuration by a design that is foldable and unfoldable.
In addition, an angle sensing system and a speed regulating mechanism are arranged in the control system, the steering condition of the light electric scooter is monitored in real time through the angle sensing system (for example, the steering condition of the front wheels is monitored), and when the steering angle or the steering change rate exceeds a preset threshold value, the running speed of the light electric scooter is reduced through the speed regulating mechanism, so that the light electric scooter is prevented from excessively inclining or even overturning the scooter body due to overhigh speed when the scooter turns, and the safety of the light electric scooter is improved.
