[0043] Please refer to 1-8. This article provides an electric cart 10, including a body 1, a drive component 2 and a control component 3. A wheel 11 is provided at the bottom of the body 1; the drive component 2 is provided on the body 1 and electrically connected to the wheel 11; the control component 3 is communicatively connected with the drive component 2 to control the drive component 2 to drive the wheel 11 to move.

[0044] In the electric cart 10 herein, the user can operate the control component 3 so that the control component 3 can control the operation of the drive component 2, so that the drive component 2 drives the wheels 11 to rotate, providing power for the movement of the cart, so that the cart can be electrically driven according to the user's operation, further allowing the user to move the cart more easily, greatly reducing the user's physical exertion and facilitating the user's use.

[0045] It is worth noting that the drive assembly 2 can be electrically connected to the built-in hub motor of the wheel 11 to drive the motor to rotate, thereby moving the wheel 11. The drive assembly 2 can include a circuit board disposed on the vehicle body 1, including a drive control chip for driving the hub motor to rotate. The control assembly 3 can include a control chip that receives user operation signals and transmits them to the control assembly 3 to drive the hub motor to rotate.

[0046] In some respects, see Figure 3-4 The control assembly 3 includes an operating member 31 and a control member 32. The control member 32 senses the operating instructions of the operating member 31 to control the drive assembly 2. The operating member 31 is a structure manually operated by the user and can transmit the user's hand operation to the control member 32, so that the control member 32 can receive the control signal and control the drive assembly 2 to drive the hub motor to rotate according to the control signal, so that the wheel 11 rotates.

[0047] In some respects, see Figure 3The control member 32 includes a main control unit 321 and an inductive sensor 322. The inductive sensor 322 is electrically connected to the main control unit 321. The operating member 31 includes an operating unit 311 and a trigger unit 312. The trigger unit 312 is connected to the operating unit 311. The operating unit 311 can drive the trigger unit 312 to move, and the inductive sensor 322 can sense the movement of the trigger unit 312. The main control unit 321 can control the drive assembly 2 based on the sensing of the inductive sensor 322. In this configuration, when the user triggers the operating unit 311, the trigger unit 312 can move relative to the inductive sensor 322, causing the inductive sensor 322 to generate a corresponding signal. The main control unit 321 can receive the corresponding signal and control the drive assembly 2 to rotate the wheel 11. Specifically, the trigger unit 312 can be a magnet, and the inductive sensor 322 can be a Hall sensor, specifically a linear Hall sensor, which can be used to indicate the strength of a magnetic field. The magnet is connected to the operating unit 311, and the Hall sensor is disposed on the pusher 14 and is arranged opposite the magnet.

[0048] In some embodiments, the vehicle body 1 is provided with a pusher 14, a main control unit 321 is disposed on the pusher 14, and an operating unit 311 is movably disposed on the pusher 14. With this arrangement, a user can lean on the pusher 14 and operate the operating unit 311. The operating unit 311 drives the magnet relative to the linear Hall effect sensor, causing the linear Hall effect sensor to output a corresponding signal. The main control module then receives the signal from the linear Hall effect sensor and controls the vehicle's movement, such as forward and reverse. Furthermore, the user can adjust the cart's deflection direction through the pusher 14, enabling the cart to turn, for example.

[0049] In some embodiments, an elastic member 4 is further included, and the operating portion 311 has a receiving groove 3111. The elastic member 4 is arranged in the receiving groove 3111, and one end of the elastic member 4 abuts or is connected to the pushing portion 14, and the other end abuts or is connected to the operating portion 311, so that the operating portion 311 is elastically connected to the pushing portion 14. The elastic member 4 is used to enable the operating portion 311 to be reset. When the user releases the operating portion 311, the operating portion 311 can be reset relative to the pushing portion 14.
