Description

Technical Field

[0001] The present invention relates to the field of electric motorcycles, and in particular to an integrated electric motorcycle display and control instrument panel. Background Art

[0002] In recent years, motorcycles have become widely popular as a convenient and fast means of transportation. Traditional motorcycle display and control systems typically employ a distributed modular design, with separate modules implementing different functions such as headlight control, anti-theft alarm, horn control, and turn signal control. While this design approach was common in early applications, its limitations have become increasingly apparent with the increasing sophistication of user needs and the continuous development of motorcycle technology.

[0003] The shortcomings of the existing technology are mainly manifested in the following aspects:

[0004] Since each functional module adopts an independent hardware design, additional wiring and connection are required, resulting in higher material and production costs.

[0005] In traditional electric motorcycles, various functional modules need to be connected to each other through a large number of wires. The wiring is complicated and prone to signal interference problems, affecting the stability and reliability of the system.

[0006] Due to the scattered modules and complex circuit connections, the system failure rate of the entire vehicle is high, which increases the maintenance cost in daily use.

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

[0008] The distributed module design of existing technology makes it easy for users to modify electric motorcycles at will, such as increasing the speed, removing the anti-theft module, etc., which increases potential safety hazards. Summary of the Invention

[0009] In order to solve the above problems, the present invention provides an integrated motorcycle display and control instrument panel, which integrates multiple functions into a set of circuit boards through highly integrated design, thereby achieving comprehensive optimization of the motorcycle display and control functions.

[0010] The present invention is achieved through the following technical solutions: an integrated electric motorcycle display and control instrument panel, comprising:

[0011] Battery module, used to provide power to the instrument panel system;

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

[0013] An input and output processing module, connected to the main control module, for controlling the vehicle's external devices, including interfaces for headlights, turn signals, and brake lights;

[0014] A display module, connected to the main control module, for displaying vehicle operation status information;

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

[0016] A fast charging module, connected to the battery module and controlled by the main control module, provides a fast charging function for external devices;

[0017] The positioning module, including the Beidou / GPS module and the 4G module, is connected to the main control module by plugging and is used to provide positioning, navigation and remote communication functions;

[0018] The anti-theft module is connected to the main control module and is used to realize the anti-theft alarm and remote locking functions of the vehicle;

[0019] A diagnostic port module, connected to the main control module, for detecting the vehicle's operating status and outputting a diagnostic signal;

[0020] The motor controller is connected to the main control module and the battery module and is used to adjust the operating state 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 various modules and output control signals after performing logical processing.

[0022] As an optimal 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 an 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 the vehicle brake signal and control the brake lights to light up.

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

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

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

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

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

[0029] Second, because 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 motorcycles, and significantly improving the stability and reliability of the system;

[0030] Third, the present invention reduces the space occupied by independent modules and wiring through the high integration of functional modules. At the same time, the speaker-sharing design enables the same speaker to sound both the whistle and the anti-theft alarm, further saving space in the vehicle and providing greater freedom in vehicle design.

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

[0032] 5. The NFC module provides a more convenient way to lock and unlock the vehicle. Seamless integration with mobile phones further enables intelligent unlocking and optimizes the user experience. In addition, the sound and light synchronization function of the turn signal and flash light effectively enhances the driver's safety awareness and reduces the risk of accidents caused by improper operation.

[0033] 6. Since all functional modules are integrated on the same circuit board, maintenance personnel only need to inspect and maintain the circuit board without having to check the scattered functional modules one by one, which greatly reduces the complexity of installation, debugging and maintenance and improves the user's maintenance efficiency.

[0047] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0048] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0049] like Figures 1-12 As shown, the integrated electric motorcycle display and control instrument panel of the present invention includes a battery module, a main control module, an input / output processing module, a display module, a communication module, a fast charging module, a positioning module, an anti-theft module, a diagnostic port module, and a motor control module. These modules are connected on a single circuit board through circuits, forming a highly integrated design, improving system reliability and reducing wiring complexity and production costs.

[0050] Battery modules such as Figure 9 and Figure 10 As shown, it is mainly used to provide power for the entire instrument panel system. Figure 9 The working voltage output of 5V and 12V is achieved through a step-down circuit. The circuit includes inductor L3, filter capacitors C21, C22 and Zener diode D10, which are used to filter out high-frequency noise and ensure stable output. Figure 10 The detailed circuit design for 12V voltage conversion is further demonstrated. The core component, EG1163, adjusts the output voltage through a feedback network, and overvoltage protection is provided by MOS transistor 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] The main control module is as follows Figure 1 Figure 1 shows the core control unit of the present invention, which utilizes the HK32F030R8T6 main control chip. The main control module connects to the input / output processing module, display module, and communication module via a communication bus. Its internal GPIO interface connects to the signal input and output terminals of each module. Through the logic operations within the core chip, the main control module rapidly processes signals from sensors and user input, outputs control commands, and enables coordinated operation of the entire system.

[0052] Input and 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 by 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 and overloads, the module incorporates a protection circuit, including a current sensing resistor R9 and a freewheeling diode D4, to ensure safe and reliable operation.

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

[0054] Communication modules such as Figure 2 and Figure 3 As shown in the figure, it includes NFC module and Bluetooth module. Figure 2 As shown in the figure, its main components are embedded antenna and peripheral filtering circuit. NFC_RST interface is used to reset the module. When the vehicle needs to be unlocked or locked, the signal is received by the antenna and transmitted to the main control module to ensure the accuracy of communication and fast response. Figure 3 As shown in the figure, its peripheral circuit includes the antenna, filter capacitors C6 and C7, and DC blocking inductor L2. The figure shows that the Bluetooth chip's main signal terminals include RX, TX, and WAKEUP interfaces. RX is responsible for receiving data, TX is responsible for sending data, and WAKEUP is used to wake up the Bluetooth module. When an external device is paired with the Bluetooth module, the signal is transmitted through the RX terminal to the main control module for processing.

[0055] Fast charging module such as Figure 6 As shown, it includes a USB interface and a fast-charging chip, the FS9112K. The USB interface is connected to the main control module via the VBUS pin. The VBUS signal is used to detect the connection status of external devices. The fast-charging chip regulates the output voltage and current through peripheral components such as inductor L1, capacitor C1, and freewheeling diode D2. An overload protection circuit is incorporated into the module, with R12 for current detection and Q3 as a protective MOSFET. When abnormal current is detected, the main control module can control the MOSFET to shut down through the GPIO interface, cutting off the power output.

[0056] Positioning module such as Figure 4 As shown, it includes a Beidou / GPS module and a 4G module, which are connected to the main control module via plug-in. The Beidou / GPS module's main interfaces include RXD (data reception) and TXD (data transmission). Signals enter the main control module through external filter capacitors C130 and C131. The main control module parses the location information and displays it on the instrument panel or uploads it to the cloud via the 4G module. The 4G module's power supply circuit uses a voltage regulator chip U3 and filter inductor L3 to ensure power supply stability and anti-interference capabilities during signal transmission.

[0057] Anti-theft module such as Figure 5As shown, it primarily consists of a 433MHz remote control receiver chip, the WS490H, and an alarm driver circuit. The 433_DAT interface connects to the main control module, transmitting remote control signals. The alarm driver circuit controls the buzzer and turn signal via MOS transistor Q5. Resistor R25 is used for current limiting, and D8 is a freewheeling diode to protect the circuit from reverse current surges. The anti-theft module also supports a silent alarm function. The main control module can silence the buzzer and only flash the alarm to avoid disturbing the surrounding environment.

[0058] Diagnostic port module such as Figure 1 and Figure 8 As shown, the module includes a standard plug-in interface for connecting external diagnostic equipment. The module transmits vehicle operating parameters to the main control module via the resistor divider network R10 and R11. Once the diagnostic equipment is connected, maintenance personnel can use the interface to read the operating status of the battery module and motor control module and quickly locate the fault point.

[0059] Motor control module such as Figure 1 As shown, it is responsible for regulating the operating status of the vehicle's motor. The module's speed limit adjustment unit uses a PWM signal to adjust the motor speed. The main control module controls the PWM duty cycle via the GPIO interface, achieving precise speed control. The module also features a soft start adjustment function. A buffer network composed of resistor R8 and capacitor C3 reduces the inrush current at motor startup, improving the driving experience.

[0060] Real-time clock module such as Figure 11 As shown, the module includes the SD2059 real-time clock chip and its backup battery. The module connects to the main control module via an I2C communication interface. The CLK signal synchronizes time data, and the backup battery provides power to the clock chip during power outages, ensuring time continuity. The main control module uses the clock signal to implement timed activation of anti-theft modes, such as automatically activating the alarm mode at night.

[0061] This invention utilizes a highly integrated modular design, concentrating all functions on a single circuit board to ensure efficient system operation. The circuit design incorporates overload protection, signal filtering, and anti-interference features, significantly improving system reliability, security, and user experience while effectively reducing production costs and maintenance.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
