Description

Technical Field

[0001] This utility model relates to the field of intelligent accessories for electric bicycles, specifically to a communication cloud box for electric bicycles. Background Technology

[0002] With the increasing popularity of electric bicycles in urban short-distance travel, users' demands for intelligent vehicle management, safety protection, and remote monitoring are rising. The integration of vehicle networking technology with electric bicycles has become a significant trend in the industry. Currently, most mid-to-low-end electric bicycles on the market still use traditional local control and instrument display architectures. Their core functions are concentrated on vehicle driving control, local battery level display, and basic fault indication, lacking remote communication and positioning capabilities, thus failing to meet current users' core demands for vehicle intelligence. Existing electric bicycle technical solutions suffer from the following problems:

[0003] (1) Lack of remote communication capabilities. The vehicle lacks a cellular mobile communication module, making it impossible to establish a data connection with a remote cloud platform. This prevents users from obtaining real-time remote status information of the vehicle, and also prevents timely notifications to users or the maintenance platform when vehicle malfunctions. Furthermore, manufacturers face difficulties in performing batch remote management of vehicles, hindering the implementation of value-added services such as firmware upgrades and parameter optimization.

[0004] (2) Lack of positioning and anti-theft functions. Most existing models do not integrate GNSS positioning modules and rely solely on physical locks for basic anti-theft. Once a vehicle is stolen, users cannot track the vehicle's real-time location and driving trajectory, making subsequent recovery extremely difficult. Even some high-end models equipped with simple positioning devices are mostly independent modules that are not linked to the vehicle's overall status data. They cannot be combined with information such as the vehicle's ignition status and battery level changes to determine whether there is abnormal movement, resulting in insufficient accuracy and practicality in anti-theft.

[0005] (3) Insufficient data interaction and remote control capabilities of the whole vehicle. The instrument and vehicle control system of traditional electric bicycles only realize data interaction through local lines. The data can only be displayed locally on the vehicle and cannot be uploaded to the cloud platform for storage and analysis. At the same time, users cannot remotely control the vehicle through mobile terminals or cloud platforms. When the vehicle is unattended, there is a lack of emergency control measures, and the safety and flexibility of use are significantly reduced.

[0006] Therefore, a communication cloud box with high integration, comprehensive functions, and adaptability to the usage scenarios of electric bicycles is needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] This embodiment of the electric bicycle communication cloud box uses a Cat.1 communication module as its core hardware unit, integrating a GNSS positioning module, a Bluetooth communication module, a power supply module, interface circuits, auxiliary circuits, and antenna components. Through a compact hardware layout and collaborative design, it achieves core functions such as cellular communication, high-precision positioning, and Bluetooth instrument interaction, fully adapting to the voltage fluctuations, space constraints, and anti-interference requirements of the electric bicycle's onboard environment. Each module establishes stable signal interaction and power supply connections through optimized circuit routing. Component layout strictly adheres to the principle of minimizing signal interference, with key components placed close to their corresponding module pins to ensure overall operational stability. Figure 1 , Figure 2 As shown below, the modules and workflows are explained in detail:

[0026] (1) Main control module. A Cat.1 communication module is used as the core processing unit to coordinate the startup, data interaction and command execution of various functional modules. The module power supply is connected to a VCC_LTE power supply with a voltage range of 3.0V to 4.2V, which can meet the dynamic voltage requirements in the vehicle environment.

[0027] The module circuit is equipped with a USIM card interface circuit, which connects to the USIM_DATA, USIM_RST, and USIM_CLK pins via dedicated resistors to ensure stable communication between the SIM card and the module. The circuit includes a 0.1µF 50V capacitor and a 4.7µF 10V capacitor, all soldered close to the Cat.1 module pins to filter out power supply noise and signal interference, thus improving communication stability.

[0028] The module is equipped with dedicated GPIO pins, which are connected to a green LED indicator and a reset circuit, respectively. The green LED indicator provides real-time feedback on the module's operating status, remaining constantly lit during normal operation, flashing during data transmission, and turning off in case of an abnormality. The reset circuit is connected to the Reset pin via resistor R39, which can automatically trigger a reset and restart when the module experiences a communication interruption or functional malfunction, quickly restoring operation.

[0029] (2) Positioning Module. A high-performance GNSS positioning module is used, which establishes bidirectional communication with the Cat.1 module via the UART serial port, specifically pins 28 (AUXRXD) and 29 (AUXTXD). The GNSS module searches for satellite signals in real time and continuously outputs positioning data containing information such as positioning status, latitude and longitude, timestamp, and positioning accuracy. This data is then transmitted to the Cat.1 module via the serial port, where the Cat.1 module performs data parsing and format encapsulation.

[0030] The positioning module circuit integrates an antenna matching unit, and the ANT MAIN interface connects to an external ceramic antenna or rod antenna, which can enhance satellite signal reception strength in complex vehicle environments and ensure positioning continuity in obstructed scenarios. An 8.2 picofarad 50V capacitor is included in the circuit for signal filtering to prevent external electromagnetic interference from affecting the accuracy of positioning data transmission. The module's BDSReset pin is connected to a reset circuit, which can output control signals through the Cat.1 module to achieve remote restart and calibration of the positioning module, further improving positioning accuracy.

[0031] (3) Bluetooth Communication Module. The Bluetooth communication module establishes a stable connection with pins 17 and 18 of the Cat.1 module via the UART serial port, realizing bidirectional data interaction with the Bluetooth instrument panel of the electric bicycle. The module receives the vehicle status information transmitted by the Bluetooth instrument panel in real time, including key data such as battery voltage, driving speed, remaining power, fault codes, and ignition status, and transmits it synchronously to the Cat.1 module to update the internal status database of the cloud box; at the same time, it feeds back the remote control commands issued by the Cat.1 module to the Bluetooth instrument panel to trigger the vehicle to perform the corresponding operation.

[0032] The circuit design employs a one-line interconnect architecture, achieving efficient data transmission through the OneLine TX and OneLine RX pins. A zero-ohm resistor is configured as a line matching element to reduce signal attenuation during data transmission. The module's operating status is precisely controlled by the GPIO20 pin of the Cat.1 module, ensuring communication synchronization with the Bluetooth instrument and preventing data loss or command delays.

[0033] (4) Power Module. The power module supports wide voltage input characteristics and can be adapted to the voltage of common electric bicycle batteries ranging from 12V to 60V. The module converts the battery voltage to a stable 5V output through a wide voltage to 5V circuit, and then performs secondary voltage regulation through a 5V to 4V circuit and a 4V to 3.3V circuit, providing accurate adaptation voltages for the Cat.1 module, GNSS module and Bluetooth module respectively, ensuring stable operation of each module.

[0034] The module features a built-in dual power supply switching unit. When the vehicle battery voltage experiences momentary fluctuations or a brief power outage, it automatically switches to the backup power supply circuit, ensuring continuous power supply. The circuit incorporates a 220µF 10V surface-mount capacitor and a 1µF 16V capacitor for energy storage and filtering, respectively, effectively suppressing the impact of voltage fluctuations on the operation of each module. An integrated ADC detection circuit collects power input voltage data in real time and transmits it to the Cat.1 module for monitoring. When the voltage exceeds the safe range, an alarm is triggered and uploaded to the server.

[0035] (5) Interface and auxiliary circuit. The interface circuit includes the ACC detection interface and the vehicle status acquisition interface. The ACC detection interface obtains the vehicle ignition status signal through the ADC pin to accurately determine whether the vehicle is in driving or standby mode; the vehicle status acquisition interface collects the core data of the battery management system through the ADC detection circuit, including information such as battery charging and discharging current, cell temperature, and remaining capacity, to provide data support for vehicle status assessment.

[0036] The auxiliary circuit consists of an EEPROM storage unit, a reset circuit, and a grounding system. The EEPROM storage unit is used to persistently store key information such as device parameters, historical location data, and fault records. The data is not lost after power failure, facilitating subsequent traceability and analysis. The reset circuit is connected to the PWRKEY pin through a 1K ohm resistor R107, which can realize the overall system reset and solve the abnormal stuttering problem when multiple modules work together. The grounding system adopts a multi-point grounding design, with the GND pins of all modules connected to a unified grounding network to minimize electromagnetic interference and ensure the stability of signal transmission of each module.

[0037] The workflow of this embodiment is described as follows:

[0038] (1) After the cloud box is powered on, the power module immediately starts the voltage conversion process to provide a stable adaptation voltage for the Cat.1 module, GNSS module, Bluetooth communication module, etc. The Cat.1 module starts up synchronously and completes the initialization configuration of each communication interface. The green LED indicator lights up to indicate that the system is ready.

[0039] (2) The GNSS module starts the satellite search process. After successfully capturing the satellite signal, it continuously transmits positioning data to the Cat.1 module through the UART serial port. The Cat.1 module parses the data according to the preset protocol and completes the format encapsulation to form a standardized positioning information packet.

[0040] (3) The Bluetooth communication module automatically scans and establishes a pairing connection with the Bluetooth instrument of the electric bicycle, obtains the vehicle status information in real time, transmits it synchronously to the Cat.1 module, updates the internal status library of the cloud box, and ensures that the data is consistent with the actual status of the vehicle.

[0041] (4) The Cat.1 module establishes a stable communication link with the remote server through the cellular network, and reports the encapsulated positioning data and vehicle status information in real time at a fixed period. At the same time, it continuously listens for the control commands issued by the server to ensure that the commands are received in a timely manner.

[0042] (5) When the server control command is received, the Cat.1 module quickly parses the command content and transmits it to the Bluetooth instrument through the Bluetooth communication module, triggering the vehicle to perform remote locking, unlocking, and restricted start operations. After the operation is completed, the LED indicator flashes to indicate that the command was successfully executed, and the execution result is sent back to the remote server.

[0043] The electric bicycle communication cloud box in this embodiment achieves comprehensive technological improvements in remote communication, positioning and anti-theft, and intelligent management through hardware integration design and multi-module collaborative work. It not only meets users' core needs for vehicle safety monitoring and convenient operation, but also meets the development trend of the electric bicycle industry towards intelligence and connectivity.

[0044] It should be noted that the functions described in this embodiment require the cooperation of software and other related programs to be fully realized; the aforementioned software and other related programs are not the technical solutions claimed by this utility model and are not within the protection scope of this utility model.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
