Referring to fig. 1, the present invention provides a two-wheeled vehicle-based mechanical load limiting device, which includes a rack 1, a gear 2, a gear shaft 3, a clockwork spring 4, an elastic member 5, and a slide rheostat 6, wherein the gear 2 is mounted on the gear shaft 3 and engaged with the rack 1, the gear shaft 3 is connected to a two-wheeled vehicle powertrain 7, the clockwork spring 4 is mounted on the gear shaft 3 for limiting rotation of the gear 2, a top end of the rack 1 is connected to a seat cushion 8 of the two-wheeled vehicle, a bottom end of the rack is connected to one end of the elastic member 5, and another end of the elastic member 5 is connected to the slide rheostat 6.

Specifically, the two-wheeled vehicle is a shared electric two-wheeled vehicle. The power assembly 7 is connected with a storage battery 9. The elastic piece 5 is a tension spring.

The invention provides a mechanical load limiting device based on a two-wheel vehicle, which has the following working principle:

under the condition that the electric two-wheeled vehicle is used in an overload state, the cushion 8 presses the rack 1 downwards to drive the gear shaft 3 to rotate, the spiral spring 4 contracts, the elastic piece 5 contracts, and after the set elastic potential energy of the spiral spring 4 is reached, the rack 1 presses the slide rheostat 6 downwards, and the rotation speed of the motor is reduced to limit the operation of the electric two-wheeled vehicle. If a dynamic load occurs, the device can restore the slide rheostat 6 through the elastic piece 5, and the device does not work.

The invention has the following beneficial effects: the elastic potential energy of a spring is used as an overload measuring index, and the sliding rheostat is used for increasing the resistance of a power circuit to reduce the rotating speed of the motor to limit the running of the two-wheel vehicle, so that the existing overload condition is effectively reduced.
