Express car dual power unit

Abstract

The invention discloses a dual power device for an express vehicle. It includes the frame and two pedal mechanisms installed on the frame, two reversing shaft mechanisms, gear shaft mechanisms, wheel shaft mechanisms, motor mechanisms and dual power switching mechanisms, and the two pedal mechanisms are respectively placed on both sides of the frame And installed symmetrically, the two ends of the gear shaft mechanism are connected with the reversing shaft mechanism, the reversing shaft mechanism is respectively connected with the pedal mechanism on both sides, the middle part of the gear shaft mechanism is connected with the wheel shaft mechanism through chain transmission, and the motor is connected to the wheel shaft mechanism mechanism, the wheel shaft mechanism is respectively connected with the gear shaft mechanism and the motor mechanism through the dual power switching mechanism, and realizes the mutual switching between the pedal power and the electric power. The invention can make the pedal swing within a range of 90 degrees, and drive the trolley forward through the two-stage gear set and the sprocket speed increase; compared with the pedal turning around the whole circle, it is easier and labor-saving, and the structure is more compact, realizing the human-driven and motor-driven Feel free to switch.

Description

technical field [0001] The invention relates to a vehicle power device, in particular to a dual power device for express vehicles, which solves the problems of low efficiency and high work intensity for couriers in high-end office buildings to send and receive express delivery on foot. Background technique [0002] With the rapid development of e-commerce, the express delivery industry is becoming more and more prosperous. In high-end office buildings with extremely dense population, since white-collar workers are all in the company, they often choose to sign for express delivery in the company, and the express delivery volume of a single high-end office building is huge. [0003] Couriers traditionally use sacks or small flatbeds to load packages, and use the original way of walking to deliver them layer by layer. In this way, the three factors that can be carried in a single delivery, walking speed and physical endurance The existence of express delivery makes it impossibl...
