[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-6 This utility model provides an embodiment of an electric-assisted flatbed trolley, including a trolley base 1, electric wheels 3, and a drive assembly. The drive assembly includes a main control module 5 and a battery pack 6. Electric wheels 3 are located on both sides of the front bottom of the trolley base 1, and driven wheels 4 are located on both sides of the rear bottom of the trolley base 1. The electric wheels 3 and driven wheels 4 are rotatably connected to the trolley base 1. The main control module 5 and the battery pack 6 are located at the bottom of the trolley base 1 and are fixedly connected to the trolley base 1. A trolley handle 2 is located at the rear of the trolley base 1, and the trolley base 1 is rotatably connected to the trolley handle 2. A connection is provided at the junction of the trolley base 1 and the trolley handle 2. The trolley has a limiting component and a control module 7 is located above the trolley handle 2. The main control module 5 is electrically connected to the electric wheel 3, the battery pack 6, and the control module 7. By setting the main control module 5 to draw power from the battery pack 6 and drive the electric wheel 3 to rotate, the flatbed trolley can achieve electric power-assisted drive to save manpower. The operator can input commands to the main control module 5 through the control module 7 to control the operation of the motor inside the electric wheel 3, thereby switching between multiple modes such as forward, reverse, speed switching, and stop. The rotatable connection between the trolley base 1 and the trolley handle 2 allows the trolley handle 2 to be folded and stored to save space when the trolley is not in use. The limiting component limits and fixes the position of the trolley handle 2 in the use and storage states.

[0018] Please see Figure 2 In this embodiment, the trolley base 1 and the trolley handle 2 are made of hollow tubing. The trolley base 1 and the trolley handle 2 are provided with wire holes 201. A third connecting wire 503 is provided in the trolley base 1 and the trolley handle 2. The two ends of the third connecting wire 503 are electrically connected to the main control module 5 and the control module 7, respectively. The hollow tubing helps to reduce the weight of the trolley base 1 and the trolley handle 2 and save material costs. At the same time, the hollow structure and the wire holes 201 facilitate the routing of the third connecting wire 503 inside the trolley base 1 and the trolley handle 2.

[0019] Please see Figure 4 In this embodiment, a second connecting wire 502 is provided between the main control module 5 and the battery pack 6, and a first connecting wire 501 is provided between the main control module 5 and the electric wheel 3. The main control module 5 and the battery pack 6 are provided with a protective shell 504, which is fixedly connected to the trolley base 1. The protective shell 504 protects the main control module 5 and the battery pack 6. The second connecting wire 502 serves as a channel for power transmission and signal exchange between the main control module 5 and the battery pack 6, and the first connecting wire 501 serves as a channel for power transmission and signal exchange between the main control module 5 and the electric wheel 3.

[0020] Please see Figure 5 In this embodiment, a steering button 701 and a mode switching switch 702 are provided on one side of the control module 7, and a signal light 703 is provided on the other side. There are two sets of steering buttons 701 and mode switching switches 702, and the mode switching switch 702 has three positions. The two sets of steering buttons 701 serve as control buttons for steering signals. After the steering button 701 is pressed, the steering button 701 generates an electrical signal. The main control module 5 receives the steering signal and controls the two sets of electric wheels 3 to turn at different speeds or different directions of rotation. One set of mode switching switches 702 has three modes for forward, stop, and reverse, and the other set of mode switching switches 702 has three modes for movement speed. The signal light 703 is used to display the current mode and speed, and illuminates as an alarm when the battery pack 6 has low power.

[0021] Please see Figure 5 In this embodiment, the limiting component includes a connector 8 and a foot pedal 9. The connector 8 is provided at the connection between the trolley base 1 and the trolley handle 2. The trolley handle 2 is rotatably connected to the connector 8. The connector 8 has a guide groove 802, and the foot pedal 9 is provided in the guide groove 802. A tension spring 801 is provided between the foot pedal 9 and the connector 8. When it is necessary to lay the trolley handle 2 flat or stand it up, the foot pedal 9 is stepped on. The foot pedal 9 slides down in the guide groove 802 and stretches the tension spring 801. At this time, the trolley handle 2 can rotate freely. When it is necessary to lay the trolley handle 2 flat or stand it up, the foot is released, and the tension spring 801 releases energy to pull the foot pedal 9 upward to reset, thus limiting the position of the trolley handle 2.

[0022] When in use, place the goods on the trolley base 1 and switch the mode switch 702 to the forward position. The speed position of the other mode switch 702 can be switched as needed. After receiving the electrical signal from the mode switch 702, the main control module 5 draws power from the battery pack 6 and drives the electric wheels 3 to rotate, realizing the electric power-assisted drive of the flatbed trolley to save manpower. After pressing the steering button 701, the steering button 701 generates an electrical signal. The main control module 5 receives the steering signal and controls the two sets of electric wheels 3 to run at different speeds or different directions of rotation to turn.
