Braking and parking separation type braking system of electro-tricycle

The utility model provides a braking and parking separation type braking system of an electro-tricycle. The braking and parking separation type braking system comprises a braking unit and a parking unit. The brake unit comprises a foot brake, a front brake pull rod, a brake distribution shaft, a rear brake pull rod and a front brake assembly; the parking unit comprises a parking braking handle and a parking braking assembly; according to the utility model, during braking, the front brake and the rear brake are driven to move synchronously by stepping on the foot brake, and the front wheel and the rear wheel are braked at the same time, so that the braking response speed is high, the inertial sliding distance in the braking process of the tricycle is reduced, and the braking effect is enhanced; during parking, the parking braking handle is connected with braking of the rear wheels through the parking braking assembly, and parking is achieved. And when the brake distribution shaft or the rear brake pull rod has
