As shown in fig. 1, the three-wheeled electric vehicle is provided with a steering column 1, two sides of which are symmetrically and fixedly connected with a limiting lug 2, the limiting lug 2 is generally a cylindrical metal rod, and can be welded on the steering column 1, a tricycle handle is fixed on the top end of the steering column 1, an electric cylinder 6 is fixed on a frame at the rear side of the steering column 1, the electric cylinder 6 is horizontally fixed, an expansion link of the electric cylinder is positioned at the front part and can stretch back and forth, a horizontally arranged connecting rod 5 is fixed at the end part of the expansion link, two ends of the connecting rod 5 are respectively connected with the rear end of a limiting stop lever, the front end of the limiting stop lever 3 extends forwards and is positioned in a rotating area of the limiting lug 2, the limiting stop lever 3 limits the rotating area of the limiting lug 2 by utilizing the end part, thereby ensuring that the steering range is within a safe range and avoiding side rollover.

As shown in fig. 2, in order to ensure the reliability of the limit stop lever 3 in limiting, the end of the limit stop lever 3 is provided with two clamping plates extending forward, the two clamping plates clamp the limit bump 2 from the upper side and the lower side, thereby the limit stop lever 3, the outer ends of the clamping plates are connected with each other, a sliding groove structure for the limit bump 2 to slide is formed, so that the clamping plate structure is more reliable, in addition, a gasket 4 contacting with the limit bump 2 can be arranged on the opposite surface of the clamping plate, the gasket 4 contacts with the limit bump 2, the steering friction force is increased, the steering tactile sensation is improved, the steering tactile sensation can be conveniently adjusted by changing the material of the gasket 4, the surface texture and the clamping plate gap, and the high-grade sensation of the electric tricycle is improved.

The electric control system of the whole mechanism is shown in fig. 3, a control port of the electric cylinder 6 is connected with a controller, a signal input end of the controller is connected with a vehicle speed sensor, and the vehicle speed sensor acquires a vehicle speed signal of the electric tricycle and transmits the vehicle speed signal to the controller. After the vehicle is started, the vehicle speed sensor transmits a vehicle speed signal to the controller in real time, and the controller drives the electric cylinder 6 according to the comparison of a current vehicle speed value and a preset control table;

the specific control strategy is as follows:

the electric cylinder 6 is driven to extend forwards along with the increase of the vehicle speed, and the rotating interval of the limiting lug 2 is reduced;

the electric cylinder 6 is driven to contract backwards along with the reduction of the vehicle speed, and the rotating range of the limiting lug 2 is enlarged;

therefore, the side turning of the vehicle caused by large turning is avoided when the vehicle is at a high speed.

Wherein, predetermine the control table and divide into 4-8 gears with the speed of a motor vehicle, every gear corresponds the flexible size of an electronic jar 6, for example divide into 5 gears:
