Description

Technical Field

[0001] This invention relates to the field of electric bicycles, and more specifically to an integrated display and control dashboard for electric bicycles. Background Technology

[0002] In recent years, electric motorcycles have become widely popular as a convenient and fast mode of transportation. Traditional electric motorcycle display and control systems typically employ a distributed modular design, with different functions such as headlight control, anti-theft alarm, horn control, and turn signal control implemented by separate modules. While this design was common in early applications, its limitations have become increasingly apparent as user needs have become more complex and electric motorcycle technology has continued to develop.

[0003] The main shortcomings of existing technologies are as follows:

[0004] Because each functional module uses an independent hardware design, additional wiring and connections are required, resulting in higher material and production costs.

[0005] In traditional electric motorcycles, various functional modules need to be interconnected by a large number of wires, which makes the wiring complicated and prone to signal interference, affecting the stability and reliability of the system.

[0006] Due to the dispersed modules and complex circuit connections, the vehicle's system failure rate is relatively high, increasing maintenance costs during daily use.

[0007] The installation and debugging of independent modules require professional technical support, and the maintenance process is relatively complicated, which is not conducive to users' daily operation and maintenance.

[0008] The distributed modular design of existing technologies makes electric bicycles easy for users to modify at will, such as increasing speed or removing anti-theft modules, which increases potential safety hazards. Summary of the Invention

[0009] To address the aforementioned issues, this invention provides an integrated display and control dashboard for electric bicycles. Through highly integrated design, multiple functions are integrated onto a single circuit board, achieving comprehensive optimization of the display and control functions for electric bicycles.

[0010] This invention is achieved through the following technical solution: an integrated display and control dashboard for electric bicycles, comprising:

[0011] The battery module is used to provide power to the dashboard system;

[0012] The main control module, connected to each functional module, is used to receive signals, process data, and output control signals.

[0013] An input / output processing module, connected to the main control module, is used to control external vehicle devices, including interfaces for headlights, turn signals, and brake lights.

[0014] The display module, connected to the main control module, is used to display vehicle operating status information;

[0015] The communication module, including a Bluetooth module and an NFC module, is connected to the main control module and is used to realize wireless communication and near-field communication functions;

[0016] The fast charging module is connected to the battery module and controlled by the main control module to provide fast charging functionality for external devices;

[0017] The positioning module, including a Beidou / GPS module and a 4G module, is connected to the main control module via a plug-in connection and is used to provide positioning, navigation and remote communication functions;

[0018] An anti-theft module, connected to the main control module, is used to realize the vehicle's anti-theft alarm and remote locking functions;

[0019] The diagnostic port module, connected to the main control module, is used to detect the vehicle's operating status and output diagnostic signals.

[0020] The motor controller, connected to the main control module and the battery module, is used to regulate the operating status of the vehicle motor.

[0021] As a preferred technical solution, the main control module includes a main control chip HK32F030R8T6, which is used to receive signals from each module, perform logic processing, and output control signals.

[0022] As a preferred technical solution, the fast charging module includes a USB interface and a fast charging chip FS9112K. The USB interface adopts a standard USB 2.0 interface, supports 5V and 12V output, and has overload protection function.

[0023] As a preferred technical solution, the input / output processing module further includes a brake signal interface, which is connected to the main control module and is used to detect vehicle brake signals and control the brake lights to illuminate.

[0024] As a preferred technical solution, the display module includes two common cathode LED driver chips AIP1640, which are used to drive the display of vehicle speed, battery level, mileage and fault information status indicators.

[0025] As a preferred technical solution, the diagnostic port module includes a standard connector, which is connected to the main control module via a communication cable to read the operating parameters of the vehicle battery module and motor control module.

[0026] As a preferred technical solution, the anti-theft module includes a 433MHz remote control receiver chip WS490H and an alarm drive circuit. The alarm drive circuit is connected to the light signal interface and is used to drive the vehicle lights to flash in anti-theft mode.

[0027] As a preferred technical solution, the motor control module includes a speed limit adjustment unit, which receives external input signals through the main control module and adjusts the maximum operating speed of the vehicle.

[0028] The beneficial effects of this invention are: 1. This invention integrates all functions on a single circuit board through the integrated design of highly integrated chips and functional modules, reducing the number of hardware modules and eliminating the redundant wiring and connection devices required by traditional distributed modules, thereby significantly reducing production and material costs.

[0029] Second, since all functional modules are integrated into the same circuit board, the wiring is simpler, effectively avoiding signal interference and connection failures caused by the complex wiring of traditional electric bicycles, and significantly improving the stability and reliability of the system.

[0030] Third, this invention reduces the space occupied by independent modules and wiring through the high integration of functional modules.

[0031] Fourth, the integrated design of this invention effectively prevents abnormal modifications. Users cannot easily change the vehicle speed limit or remove the anti-theft module, thereby avoiding safety hazards such as speeding and loss of vehicle control caused by modifications.

[0032] Fifth, the NFC module provides a more convenient way to lock and unlock the car. The seamless connection with the mobile phone further realizes intelligent unlocking and optimizes the user experience. In addition, the sound and light synchronization function of the turn signal and flash effectively enhances the driver's safety awareness and reduces the risk of accidents caused by improper operation.

[0033] VI. Since all functional modules are integrated on the same circuit board, maintenance personnel only need to test and maintain the circuit board, without having to check each of the separate functional modules, which greatly reduces the complexity of installation, debugging and maintenance and improves the user's maintenance efficiency.

These modules are connected to the same circuit board via circuitry, forming a highly integrated design that improves system reliability and reduces wiring complexity and production costs.

[0050] Battery modules such as Figure 9 and Figure 10 As shown, it is mainly used to provide power to the entire dashboard system. Figure 9 The circuit uses a step-down circuit to achieve 5V and 12V operating voltage outputs. The circuit includes inductor L3, filter capacitors C21 and C22, and Zener diode D10 to filter out high-frequency noise and ensure stable output. Figure 10 The circuit design for the 12V voltage conversion is further demonstrated. The core component, EG1163, adjusts the output voltage through a feedback network, and overvoltage protection is provided by MOSFET Q10 and resistor R102. The battery module is connected to both the main control module and the fast charging module, providing reliable power support for the system and external devices.

[0051] Main control module such as Figure 1 The diagram shows the core control unit of this invention, which uses the HK32F030R8T6 main control chip. The main control module is connected to the input / output processing module, display module, and communication module via a communication bus, and its internal GPIO interface is connected to the signal input / output terminals of each module. Through the internal logic operations of the core chip, the main control module can quickly process signals from sensors and user input, output control commands, and achieve coordinated operation of the entire system.

[0052] Input / output processing modules, such as Figure 8 As shown, the module includes multiple interfaces for controlling external vehicle devices. The headlights, turn signals, and brake lights are controlled via MOSFETs Q3 and Q4, respectively. The brake signal interface is connected to the ADC input port of the main control module via a resistor divider network R7 and R8 to detect voltage changes in the brake signal. To prevent short circuits or overloads, the module is designed with protection circuitry, including a current sensing resistor R9 and a freewheeling diode D4, ensuring the module's safety and reliability.

[0053] Display module such as Figure 7As shown, the system includes two common-cathode LED driver chips, AIP1640, used to drive the instrument panel's display screen and indicator lights, showing real-time vehicle speed, battery level, mileage, and fault information. Each chip connects to the instrument panel's digital displays and indicator lights via multiple output terminals (such as SEG1-SEG8, GRID1-GRID12). The main control module communicates with the AIP1640 chip via an I2C interface, sending information such as speed and battery level. The LED driver chip controls the display content based on the received signals, ensuring the driver can clearly and intuitively understand the vehicle's operating status.

[0054] Communication module such as Figure 2 and Figure 3 As shown, it includes an NFC module and a Bluetooth module. The NFC module is as follows...
