Embodiment 1

[0030] Example 1: Such as Figure 1~4 As shown, a safe driving system for driving and pushing a dual-purpose electric shopping cart includes a driving system and a braking system; the driving system includes a deceleration device and a motor 2, a controller 22, a power supply 3, and a foot connected by wires. Step-on governor 4 and switch assembly 5; the controller 22, power supply 3 and foot-step governor 4 are arranged on the frame 1, the motor 2 is drivingly connected to the deceleration device, and the deceleration device is fixedly connected to the frame 1 by bolts And its power output end is drivingly connected to one of the rear wheels 6, and the rear wheel 6 is connected to the frame 1 through the steering knuckle 11, and the remaining three wheels are connected to the frame 1 through the axle rotation; the brake system includes a brake The moving pedal 7, the brake pump assembly 8, the brake disc 9 and the caliper 10; the brake pedal 7 is connected to the frame 1 throu...

Embodiment 2

[0043] Embodiment 2: This embodiment is a further improvement of Embodiment 1. The main improvement is that although Embodiment 1 solves the technical problem of walking and braking the shopping cart on a flat road, when getting on and off the elevator, the elevator has a certain As a result, the user needs to push or pull the shopping cart forcefully when getting on and off the elevator. In this embodiment, the above-mentioned defects can be avoided, specifically:

[0044] Both sides of the frame 1 are welded with cross bars 25, and elevator wheels 26 are installed at the bottom of the cross bars 25; in this embodiment, elevator wheels 26 are installed on the frame 1 for parking when going up and down the elevator to ensure that the elevator goes up and down. Security.

[0045] Except for this, this embodiment is completely the same as Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a safe driving system of a driving and pushing dual-purpose electric shopping cart. The safe driving system comprises a driving system and a braking system, wherein the drivingsystem comprises a speed reducing device, and a motor, a controller, a power supply, a foot-operated speed regulator and a switch assembly which are connected through wires; the controller, the powersupply and the foot-operated speed regulator are arranged on a frame; the motor is in driving connection with a speed reducer; the speed reducer is fixedly connected to the frame through bolts; the power output end of the speed reducer is in driving connection with one rear wheel; the rear wheel is connected with the frame through a steering knuckle; the other three wheels are rotatably connectedto the frame through wheel shafts; the braking system comprises a brake pedal, a brake pump assembly, a brake disc and a caliper; the brake pedal is connected with the frame through a bolt; and the brake pump assembly is fixedly connected to the frame. The motor, the speed reducer and a half shaft are in coaxial transmission, structural arrangement of the shopping cart is facilitated, and it is guaranteed that the shopping cart is compact in structure and small in size.

Description

Technical field [0001] The invention relates to the technical field of shopping equipment, in particular to a safe driving system for driving and promoting a dual-purpose electric shopping cart. Background technique [0002] Shopping cart generally refers to a kind of shopping equipment we use in supermarkets and shopping malls. It is an indispensable tool in our lives. Using a shopping cart when shopping can increase buyers’ demand on the one hand, and on the other hand It has further increased the seller's trading volume, which can be described as a win-win result with two birds with one stone.
