Self-discharging structure of freight electric tricycle type

The invention discloses a self-discharging structure of a freight electric tricycle type. The self-discharging structure of the freight electric tricycle type comprises a compartment (6) and a frame (7), wherein the compartment (6) is connected with the rear end of the frame (7) via a hinge pin. The self-discharging structure also comprises a hydraulic power unit (3) capable of providing power, a lifting oil cylinder (1), a battery (5) and a switch (4), wherein the lifting oil cylinder (1) is connected with the hydraulic power unit (3) by a hydraulic oil pipe (2); the battery (5) provides energy for the hydraulic power unit (3); the switch (4) controls the hydraulic power unit; the upper end of the lifting oil cylinder (1) is connected with the compartment (6); the lower end of the lifting oil cylinder (1) is fixedly arranged in the frame (7) by a fixed support (8). According to the self-discharging structure, one set of hydraulic lifting mechanism is additionally arranged on the chassis of the electric tricycle, and the self storage battery of the electric tricycle is used for supplying power to the hydraulic power unit to drive the lifting oil cylinder to realize an automatic discharging function.
