[0010] The integrated control chip has a preset program, which is displayed on the LCD screen and sends control information to the main controller.

[0011] The function keys include at least a start key, an adjustment key, and a mode key. When the function keys are pressed, the key information is sent to the integrated control chip via the key driver circuit board to control the program.

[0012] The start button is used to turn on the LCD central controller and drive motor with one click, so that the electric scooter enters the ready state.

[0013] The adjustment key is used to switch the control of different functional components, and the mode key causes the functional component to enter the corresponding mode.

[0014] The main controller receives speed adjustment information from the Hall sensor and control information from the integrated control chip, and sends execution instructions to the corresponding functional components to control the electric scooter.

[0015] A further preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the integrated trigger further includes a housing, the Hall sensor component and the key drive circuit board are disposed inside the housing, the dial extends out of the housing from the inside of the housing to one side of the housing, and the function key is disposed on the upper surface of the housing.

[0016] A further preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the integrated control chip includes an LCD driving module, an information communication module, and a storage processing module.

[0017] A further preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the adjustment key includes an up key and a down key, and the LCD central controller and the integrated trigger are connected through a five-pin male and female electrical connector.

[0018] A further preferred technical solution adopted by the present invention to solve the above-mentioned technical problems is: an electric switch is provided between the LCD central controller and the main controller.

[0032] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0033] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0034] like Figure 1 As shown, the electric scooter includes a frame consisting of a front frame 100, a footboard 200, and a rear frame 300, as well as a front wheel 400 and a rear wheel 500. The front frame 100, from top to bottom, includes a handlebar 101, a vertical post 102, and a wheel frame 103. The vertical post 102 is connected to the footboard 200 via its front beam 104, giving the electric scooter an L-shaped structure. At least one of the front wheel and the rear wheel 500 is equipped with a drive motor 10, which rotates the wheel to propel the electric scooter.

[0035] like Figure 1-3 As shown, the electric scooter control system includes a main controller 1, an LCD central controller 2, an integrated trigger 3, and several functional components. The main controller 1 is mounted on the frame, particularly within the frame of the footrest 200. The LCD central controller 2 is mounted on the handlebar crossbeam 101a, and the integrated trigger 3 is mounted on one side handlebar 101b. The functional components described here include at least a drive motor 10. They may also include various lighting display components or a lighting control module 20 that integrates and controls these components. The lighting display components include a taillight 30, a headlight 40, and an ambient light 50. The taillight 30 includes turn signals and brake lights.

[0036] like Figure 2 , 4 As shown in Figure 6, the integrated trigger 3 includes a dial 32, a Hall effect sensor 33, a function button 34, and a button drive circuit board 35, all integrated on the same housing 31. The outer side of the housing 31 has an arc-shaped opening K, and the dial 32 extends outward from the inside of the housing 31 through the arc-shaped opening K and can rotate along the arc-shaped opening K.

[0037] The Hall effect sensor assembly 33 includes a Hall effect sensor 33a and a magnetic element 33b, which are separately disposed on either the housing 31 or the dial 32. Rotation of the dial 32 changes the relative position of the Hall effect sensor 33a and the magnetic element 33b, thereby triggering the Hall effect sensor assembly 33 to generate different signals to form speed control information.

[0038] like Figure 2-3 As shown, the Hall sensor component 33 is connected to the main controller 1, and the main controller 1 sends speed control information to it. The main controller 1 obtains the speed control information and controls the motor speed or reverses it, thereby directly realizing speed control.

[0039] The function key 34 is connected to the LCD central controller 2 via the key driver circuit board 35, and sends key information to the LCD central controller 2 to realize the control corresponding to the key.

[0040] The LCD central controller 2 includes an LCD display screen 21 and an integrated control chip 22. The integrated control chip 22 is connected to the LCD display screen 21, the button driver circuit board 35, and the main controller 1. The integrated control chip 22 has a preset program, which is displayed on the LCD display screen 21 and sends control information to the main controller 1.

[0041] It should be noted that the LCD display 21 shows the operation interface corresponding to the program, and the user can use the function keys 34 to operate the functions indicated on the interface. Simultaneously, the LCD display 21 will also display the electric scooter's driving status information collected by the integrated control chip 22 and sent by the main controller 1. This driving status information includes vehicle speed, light display status, and battery level information.

[0042] The function buttons 34 include at least a start button p, an adjustment button, and a mode button M. The start button p is used to turn on the LCD central controller 2 and the drive motor 10 with one click, putting the electric scooter into a ready state. The adjustment button is used to switch the control of different functional components, and the mode button M puts the functional components into the corresponding modes. The main controller 1 receives the control information from the integrated control chip 22 and sends execution commands to the corresponding functional components to realize the control of the electric scooter.

[0043] In this way, the entire control of the electric scooter is integrated into a single component, the integrated trigger 3, making operation more convenient and the circuit structure simpler. Furthermore, users can control the integrated trigger 3 via buttons to switch the operating interface displayed on the LCD screen 21 in real time, visually representing the operation process. This enhances the enjoyment of operation, facilitates the timely detection of misoperations, and improves operational safety.

[0044] Furthermore, the speed-regulating Hall sensor component 33 is directly connected to the main controller 1 instead of going through the LCD central controller 2 again. This is because speed regulation emphasizes timeliness and efficiency, and shortening the control path helps improve control efficiency and further enhances the safety of the electric scooter.

[0045] like Figure 1 , 4 As shown in Figure 6, the function button 34 of the integrated trigger 3 is located on the upper surface of the housing 31, and the exposed part of the shifter 32 is close to the handlebars. The user can easily adjust the speed by hooking the shifter 32 with the ring and little fingers, while the thumb can easily press the function button 34 for mode control. The LCD central control unit 2 is located in the middle of the handlebar crossbeam 101a, allowing the user to simultaneously adjust the speed and operate the function, switch displays, and easily look down to view the interface on the LCD display screen 21 more clearly.

[0046] like Figure 1 , 4 As shown in Figure 6, the housing 31 extends downward to form a connecting portion L. The connecting portion L includes a base L1 and an annular curved portion L2. The annular curved portion L2 wraps around the body from bottom to top, forming a clamp structure with an adjustable transverse hole diameter. The free end of the annular curved portion L2 is connected to the base L1 by a screw. The integrated trigger 3 can be mounted on the handlebars of the electric scooter through the connecting portion L.

[0047] like Figure 2 As shown, the aforementioned functional components can refer to the lighting control module 20. The lighting control module 20 connects the main controller 1 and each lighting display component. After receiving the execution command from the main controller 1, the lighting control module 20 adjusts the lighting status of each lighting display component to achieve integrated management and control, and also avoids the line burden caused by the direct connection of each lighting display component to the main controller 1.

[0048] It should be pointed out that, such as Figure 4 As shown, the adjustment key in function key 34 can be one key or multiple keys. Switching can be achieved by pressing one key multiple times or by pressing any one of the multiple keys separately.

[0049] Preferably, the adjustment keys include an up key (U) and a down key (D), meaning the function keys 34 include a total of four keys: up key (U), down key (D), start key (P), and mode key (M). These four keys are arranged in a circular or matrix configuration.

[0050] More preferably, such as Figure 3As shown, the LCD central controller 2 and the integrated trigger 3 are connected via a first electrical connector. The first electrical connector is a five-pin male-female connector. This connector corresponds to the up button (U), down button (D), start button (P), mode button (M), and GND. GND refers to ground. Through the five-pin waterproof cable and the first five-pin male-female connector, unidirectional information transmission is achieved between the LCD central controller 2 and the integrated trigger 3.

[0051] The integrated trigger 3 and the main controller 1 are connected via a second electrical connector. This second electrical connector is a three-pin male-female connector, corresponding to the 5V power supply, GND, and signal transmission from the Hall sensor of the Hall sensor component 33. The battery connects to the main controller 1 to provide power, and the main controller 1 indirectly provides power to the integrated trigger 3. The Hall sensor unidirectionally outputs a speed control signal to the main controller 1.

[0052] Furthermore, a Universal Asynchronous Receiver / Transmitter (UART) is provided between the LCD central controller 2 and the main controller 1 to enable bidirectional signal transmission. That is, control information from the LCD central controller 2 can be transmitted to the main controller 1, and parameter information from the main controller 1 can also be transmitted to the LCD central controller 2 for display.

[0053] The LCD central controller 2 and the main controller 1 are connected via a third electrical connector. This third electrical connector is a six-pin male-female connector. The six-pin male-female connector corresponds to UART receive, UART transmit, power positive, power negative, electronic switch, and USB power input.

[0054] Furthermore, such as Figure 2 As shown, the integrated control chip 22 includes an LCD driver module 221, an information communication module 222, and a storage and processing module 223. The program is located in the storage and processing module, which processes the key information collected by the information communication module to form control information, and outputs the control information to the main controller 1 through the information communication module. The LCD driver module is the functional module that drives the LCD display screen 21 to display the information.

[0055] Preferably, such as Figure 3 As shown, a switch is installed between the LCD central controller 2 and the main controller 1. When the start button p of function button 34 is pressed, the LCD central controller 2 receives the power-on signal and outputs the power-on signal to the main controller 1 through the switch, thereby turning on the electric scooter.

[0056] The electric scooter control system provided by the present invention has been described above. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the present invention and its core ideas.

[0057] It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
