[0048] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0049] In one embodiment of the present invention, an intelligent solar warning light with tailgate usage status monitoring and its warning method are proposed. The intelligent solar warning light includes a solar charging module, a power control module, and a control warning light drive module.
[0050] The electrical signal output terminal of the solar charging module is connected to the electrical signal input terminal of the power control module, and the electrical signal output terminal of the power control module is connected to the electrical signal input terminal of the control warning light.
[0051] The warning lights of this invention are installed on both sides of the tailgate corners. A tilt switch determines whether the tailgate is operational. When the tailgate is tilted to a specified angle, such as around 60°, the warning lights activate, and the LEDs flash periodically. This warning light integrates a solar panel, battery charging circuit, battery, power on / off circuit, undervoltage protection circuit, tilt switch, microcontroller (MCU), LED driver circuit, and LEDs. The warning light is easy to install, simple to use, and features intelligent flashing control. It does not require a power supply from the car battery; the LEDs are off while the vehicle is in motion, charging via solar power, and flash when the vehicle is parked.
[0052] The working principle and technical effect of the above technical solution are as follows: In order to overcome the shortcomings of the existing technology, the present invention provides an intelligent solar warning light for tailgate usage status. It determines whether the LED light needs to be lit according to the opening angle of the tailgate during use, and uses solar charging to eliminate the need for power supply wiring harness.
[0053] This device consists of a solar panel, a battery charging circuit, a battery, a power on / off circuit, an undervoltage protection circuit, a tilt switch, a microcontroller (MCU), an LED driver circuit, and LED beads. The tilt switch monitors the tailgate angle in real time. Once the tailgate opens to the specified angle, the tilt switch activates, and the device begins operation. The MCU then controls the LEDs to turn on and off according to the set control logic, providing a visual warning.
[0054] Solar charging panels collect energy from sunlight during the day and convert it into electrical energy for output.
[0055] Batteries are used to provide the electrical power required for the system to operate.
[0056] The battery charging circuit uses the electrical energy provided by the solar panel to charge the battery.
[0057] The undervoltage protection circuit disconnects the power supply circuit after the battery voltage drops to a specified voltage to protect the battery from over-discharge.
[0058] The power on / off circuit passes through, for example Figure 3 U3 and as shown Figure 7 The Key7 shown forms the power-on / off circuit, which is used to conserve power and prevent the system from consuming power due to the flat position of the tail plate during transportation.
[0059] The tilt switch detects the tailgate opening angle in real time. When the tailgate angle is less than 60°, the power supply is disconnected. When the tailgate angle is greater than 60°, the system power supply is activated.
[0060] Microcontroller MCU (e.g.) Figure 4 As shown in the figure, it is used to control the logic of the warning light. When the circuit is powered on, it controls the light to perform the specified effect according to the pre-defined logic.
[0061] LED driver circuit (such as LED driver circuit) Figure 5 As shown in the figure, the driving circuit is used to drive the LED. After boosting the voltage, it drives the LED in a constant current manner, ensuring that the LED can work normally within the range of battery voltage fluctuation and that the brightness remains unchanged.
[0062] LED beads (such as LED lamp beads) Figure 5 , 6 (As shown in Figure 7) A total of 5 LEDs are used to emit warning lights and ensure sufficient brightness.
[0063] This system enables the tailgate to be closed while the vehicle is in motion. An integrated tilt switch and MCU disconnect the power supply to the LED lights, keeping them off and non-flickering, thus ensuring the safety of pedestrians and other vehicles. When the vehicle is stationary and the tailgate is in use, the LED lights flash intermittently as an alarm, providing safety warnings to pedestrians, electric bicycles, and motor vehicles to prevent accidental collisions. Currently, there are no similar products on the market, indicating widespread market demand. This technology will significantly improve product safety, providing safety warnings to pedestrians, electric bicycles, and motor vehicles. The system utilizes a tilt switch and MCU for control, allowing for customized LED warning light operation logic. No external power supply is required, making installation simple, quick, and easy to maintain. The system intelligently controls the solar-powered warning lights based on the tailgate's operating status.
[0064] In one embodiment of the present invention, the solar charging module includes a solar panel, a battery charging circuit, and a battery;
[0065] The electrical signal output terminal of the solar panel is connected to the electrical signal input terminal of the battery charging circuit, and the electrical signal output terminal of the battery charging circuit is connected to the electrical signal input terminal of the battery. The electrical signal output terminal of the battery is the electrical signal output terminal of the solar charging module.
[0066] The working principle and technical effect of the above technical solution are as follows: solar panels acquire light energy and convert it into electrical energy, which is then transmitted to the input of the battery charging circuit through its electrical signal output terminal; after receiving the electrical energy from the solar panels, the battery charging circuit performs voltage conversion, current control and status detection, and delivers the appropriate electrical energy to the input of the battery to achieve safe charging of the battery; after the battery stores electrical energy, it supplies power to the outside through its own output terminal.
[0067] By using solar panels to collect electrical energy and transmitting it to the charging circuit to charge the battery, the system achieves the collection, regulation, and storage of light energy into electrical energy, thus realizing the standardized acquisition of energy. The battery charging circuit manages the charging voltage to prevent battery damage due to improper charging and extends battery life.
[0068] In one embodiment of the present invention, the power control module includes a power on / off circuit, an undervoltage protection circuit, and a tilt switch;
[0069] The electrical signal input terminal of the power-on / off circuit is the electrical signal input terminal of the power control module. The electrical signal output terminal of the power-on / off circuit is connected to the electrical signal input terminals of the undervoltage protection circuit and the tilt switch, respectively. The electrical signal output terminals of the undervoltage protection circuit and the tilt switch are the electrical signal output terminals of the power control module.
[0070] The working principle and technical effect of the above technical solution are as follows: the power switch circuit controls the power on and off of the warning light, which plays the role of adjusting the warning light switch; the undervoltage protection circuit monitors the undervoltage of the power supply circuit, which plays the role of undervoltage protection; and the tilt switch performs tilt analysis, which plays the role of controlling the power supply circuit based on the tilt analysis.
[0071] The on / off circuit enables active switching adjustment of the warning lights based on the tailboard usage status, allowing for on-demand control of the warning lights' activation and deactivation, and achieving intelligent switching according to usage scenarios. The undervoltage protection circuit monitors the power supply circuit voltage to prevent abnormal operation of the warning lights due to low voltage, and also prevents damage to the power supply equipment due to excessive discharge caused by undervoltage. The tilt switch controls the power supply circuit through tilt state analysis, realizing automated control of the warning function.
[0072] In one embodiment of the present invention, the control warning light driving module includes a microcontroller (MCU), an LED driving circuit, and LED beads;
[0073] The electrical signal input terminal of the microcontroller MCU is the electrical signal input terminal of the warning light driving module. The control signal output terminal of the microcontroller MCU is connected to the control signal input terminal of the LED driving circuit, and the driving signal output terminal of the LED driving circuit is connected to the driving signal input terminal of the LED beads.
[0074] The working principle and technical effects of the above technical solution are as follows: the microcontroller (MCU) receives external input electrical signals, which plays the role of acquiring core control signals for reception and processing; the MCU outputs control signals and performs logic scheduling for the LED driver circuit, which plays the role of precise instruction transmission, start / stop of the driver circuit and control of working mode; the LED driver circuit amplifies the drive signal and adapts the power, which plays the role of signal conversion and power supply, converting the weak control signal of the MCU into the strong electrical signal required for the LED beads to work.
[0075] The microcontroller (MCU) controls the start / stop, brightness adjustment, or flashing frequency of the LED driver circuit according to the instructions of the external input electrical signal. It outputs differentiated working states of the LED beads according to the preset program logic. The LED driver circuit provides stable driving current / voltage output to the LED beads to avoid LED beads flickering, uneven brightness, or burnout due to current and voltage fluctuations.
[0076] By using a microcontroller (MCU) as the core control unit, the system enhances the intelligence and flexibility of the warning light drive control, supporting multi-mode warning logic expansion. The LED driver circuit provides adaptive driving for the LED beads, ensuring their operational stability and extending their lifespan. The three-level link signal transmission and functional coordination ensure timely response and accurate output from the warning light drive module, meeting the needs of different warning scenarios. The MCU enables rapid switching of warning light modes based on external command differences and dynamic adjustment of drive parameters based on load status feedback. The LED driver circuit provides voltage and current stabilization for the drive signals, preventing warning function failure due to abnormal power supply to the LED beads.
[0077] In one embodiment of the present invention, the warning method includes:
[0078] S1. Charge the battery using a solar charging module and obtain battery charging data;
[0079] S2. Power supply management is performed by the power control module based on battery charging data to obtain power supply management data;
[0080] S3. By controlling the warning light driver module to control the warning light drive according to the power supply management data, the warning light drive warning data is obtained.
[0081] like Figure 1 As shown, this invention comprises a solar panel, a battery charging circuit, a battery, a power on / off circuit, an undervoltage protection circuit, a tilt switch, a microcontroller (MCU), an LED driver circuit, and LED beads. Figure 2 As shown, when there is sunlight, the solar panel converts solar energy into electrical energy and charges the battery through a charging circuit. As long as the battery voltage is within the normal operating range and the tailgate is opened to a specified angle, such as 60°, [the system functions as described above]. Figure 2 The tilt switch K1 shown will then conduct, and the main control circuit will power on normally. At this time, the MCU will send a signal to the LED driver circuit and control the LED beads to achieve the function of light warning. When the tailgate closing angle is less than the specified angle, such as Figure 2 The tilt switch K1 shown will open, the main control circuit will be powered off, the LED will be turned off, and the power supply to the subsequent circuit of the tilt switch will be disconnected to save power.
[0082] With the tailgate open, tilt switch K1 is activated. If the battery is low, such as... Figure 3 As shown, U2 controls Q2 to cut off the subsequent power supply to conserve battery power and prevent over-discharge. Once the battery has recharged, the system can resume normal operation.
[0083] The tilt switch can be replaced by an accelerometer or an inertial measurement unit (IMU).
[0084] The MCU control logic can be replaced with a dedicated LED flashing chip.
[0085] The working principle and technical effects of the above technical solution are as follows: The solar charging module performs battery charging operations and monitors the charging status, converting solar energy into electrical energy to replenish the battery, while simultaneously collecting charging data such as battery voltage, charging current, and charging progress; the power control module performs real-time analysis of battery charging data and power supply strategy scheduling, dynamically adjusting the power supply mode according to the battery charging status and generating power management data adapted to load requirements; the warning light drive module controls the warning light's working status based on power management data, translating power management commands into warning light drive actions and collecting drive warning data such as light start / stop, mode, and brightness.
[0086] The power control module controls the power supply circuit, adjusts the power supply power, or switches to backup power based on the battery charging data output by the solar charging module. It also achieves precise matching of power supply parameters according to the load requirements of the warning light drive module. The warning light drive module adapts the power management data to the drive logic, avoiding warning light drive abnormalities caused by power supply mismatch. By linking the solar charging module, the power control module, and the warning light drive module through three levels of data linkage, a complete control chain is constructed, realizing closed-loop operation from solar energy acquisition to effective warning light alerts.
[0087] By using a solar charging module to convert clean and renewable energy and charge the battery, the system's reliance on traditional power sources is reduced, improving its endurance and environmental friendliness. The power control module intelligently manages battery charging data and power demand, optimizing power resource allocation and ensuring power stability and reliability. Finally, the warning light drive module provides precise drive control based on power supply status, ensuring the warning lights function effectively in different power supply scenarios and enhancing the adaptability of the warning function.
[0088] The power control module dynamically switches the power supply mode based on changes in battery charging data and flexibly adjusts the power supply according to the real-time needs of the warning light drive. Through the coordinated operation of three modules, the energy flow and signal transmission are managed throughout the entire process, preventing warning light failure or battery damage due to insufficient charging or unstable power supply. The data-driven closed-loop control design integrates the three core functions of charging, power supply, and drive, thereby improving the energy utilization efficiency of the warning light system and enabling intelligent and automated operation.
[0089] In one embodiment of the present invention, S1 includes:
[0090] Solar energy is collected through the solar charging panel of the solar charging module, and the collected solar energy is converted into electrical energy and output to the battery charging circuit.
[0091] The battery is charged using the electrical energy through a battery charging circuit to obtain battery charging data.
[0092] The working principle and technical effect of the above technical solution are as follows: the solar charging panel of the solar charging module captures and collects solar radiation energy, converting clean and renewable solar energy in nature into usable electrical energy; the battery charging circuit performs voltage regulation, current limiting and charging status monitoring on the electrical energy output by the solar charging panel, converting unstable solar power into stable power that meets the battery charging requirements.
[0093] The battery charging circuit dynamically adapts charging parameters based on the voltage / current characteristics of the solar panel's output power. It also monitors and regulates the power quality and battery status in real time during the charging process, preventing overcharging, undercharging, and low charging efficiency caused by fluctuations in solar power or mismatched charging parameters. By synergistically integrating the functions of the solar panel and the battery charging circuit, a complete charging chain is constructed, enabling the directional conversion and controllable charging process from solar energy to battery-stored power.
[0094] The solar charging panel efficiently collects solar energy and performs preliminary conversion of it into electricity, making full use of renewable energy, reducing dependence on traditional power grids or primary power sources, and improving the sustainability and environmental friendliness of the system's energy supply. The battery charging circuit adapts the electrical energy and charges the battery precisely, ensuring the safety and stability of the battery charging process and preventing problems such as battery lifespan degradation, bulging, and damage caused by improper charging. The real-time acquisition of battery charging data by the battery charging circuit enables visualization and intelligent control of the charging process.
[0095] The battery charging circuit dynamically adjusts charging parameters based on real-time changes in solar power and adaptively switches charging modes based on battery charging data feedback. The collaborative design of the solar charging panel and battery charging circuit optimizes the entire energy conversion and charging process, preventing system malfunctions due to energy waste or uncontrolled charging.
[0096] In one embodiment of the present invention, the passage S2 includes:
[0097] The tailgate usage status is collected through the power switch circuit of the power control module to obtain tailgate data; the main data collected is whether the tailgate is in a flat position (i.e., in a non-working state during transportation).
[0098] The power on / off control is performed based on the data collected from the tailgate to obtain power on / off control data.
[0099] When the power-on / off control data is power-on control, the undervoltage protection circuit collects battery voltage data based on the battery charging data to obtain battery voltage data.
[0100] The battery voltage data is compared with a preset voltage threshold to obtain voltage comparison data;
[0101] The power supply circuit control command is triggered based on the voltage comparison data.
[0102] When the power-on / off control data is power-on control, the opening angle of the tailgate is also detected by the tilt switch to obtain the tailgate angle detection data;
[0103] The tailboard angle detection data is compared with the preset tailboard angle threshold to obtain angle comparison data;
[0104] The power supply circuit control command is triggered based on the angle comparison data.
[0105] The power supply circuit control commands are the power supply management data.
[0106] The step of triggering the power supply circuit control command based on voltage comparison data includes:
[0107] When the battery voltage data is less than the preset voltage threshold, a power supply circuit disconnection command is triggered.
[0108] When the battery voltage data collected is greater than or equal to the preset voltage threshold, a power supply circuit connection command is triggered;
[0109] The power supply circuit disconnection command and the power supply circuit connection command are the power supply circuit control commands.
[0110] The method of triggering the power supply circuit control command based on angle comparison data includes:
[0111] When the tailplate angle detection data is less than the preset tailplate angle threshold, a power supply circuit disconnection command is triggered.
[0112] When the tailplate angle detection data is greater than or equal to the preset tailplate angle threshold, a power supply circuit connection command is triggered.
[0113] The power supply circuit disconnection command and the power supply circuit connection command are the power supply circuit control commands.
[0114] When one power supply circuit control command is a power supply circuit disconnection command and the other is a power supply circuit connection command, a priority analysis command is triggered to obtain the priority command, and the priority command is added to the power supply circuit control command.
[0115] The ratio of battery voltage acquisition data to a preset voltage threshold is obtained based on the priority analysis command, and the voltage ratio coefficient is obtained.
[0116] Obtain the difference between the preset voltage ratio threshold and the voltage ratio coefficient to obtain the voltage deviation coefficient;
[0117] The ratio of the tailplate angle detection data to the preset angle threshold is obtained based on the priority analysis command, and the angle ratio coefficient is obtained.
[0118] The angle deviation coefficient is obtained by comparing the angle ratio coefficient with the preset angle ratio threshold.
[0119] Obtain the preset angle weight and preset voltage weight;
[0120] Obtain the product of the preset angle weight and the angle deviation coefficient to get the angle comparison coefficient;
[0121] Obtain the product of the preset voltage weight and the voltage deviation coefficient to get the voltage comparison coefficient;
[0122] The angle comparison coefficient is compared with the voltage comparison coefficient to obtain the deviation comparison result;
[0123] The priority of the power supply circuit disconnection command and the power supply circuit connection command is determined based on the deviation comparison result, and the priority command is obtained.
[0124] By introducing preset weights, priorities can be flexibly adjusted according to actual needs, emphasizing either security or work efficiency, making it more adaptable.
[0125] The process involves quantitative calculations using ratio coefficients, deviation coefficients, weighted products, and comparative judgments, resulting in unambiguous qualitative assessments. This can be directly implemented through MCU programming. It is compatible with requirements for small undervoltage levels and large angle variations.
[0126] Conflict scenarios only occur in ΔK u <0 (undervoltage, disconnect) and ΔKθ≥0 (angle meets requirements, connect) (core conflict), or ΔK u ≥0 (voltage meets standard, connect) and ΔKθ<0 (angle does not meet standard, disconnect) (minor conflict).
[0127] The working principle and technical effect of the above technical solution are as follows: the power control module’s power-on / off circuit collects data on the tailboard’s flat position, which accurately identifies whether the tailboard is in a non-working state during transportation and obtains the core data on whether the tailboard is flat; the power control module performs power-on / power-off logic judgment and command generation based on the data collected from the tailboard, which clarifies the system’s working trigger conditions and outputs power-on / power-off control data.
[0128] When the power-on control data is set to power-on, the undervoltage protection circuit collects real-time battery voltage data based on battery charging data to obtain the current battery voltage status. The power control module compares the collected battery voltage data with a preset voltage threshold to generate voltage comparison data, determining whether the battery voltage meets the power supply requirements. Based on the voltage comparison data, the power control module triggers power supply circuit control commands, effectively managing the power supply circuit's on / off state based on voltage status. When the collected battery voltage is lower than the preset voltage threshold, a power supply circuit disconnection command is triggered to avoid the risk of low-voltage power supply; when the collected battery voltage is greater than or equal to the preset voltage threshold, a power supply circuit connection command is triggered to ensure normal power supply.
[0129] When the power-on control data is set to power-on, the tilt switch detects the tailplate opening angle in real time to obtain angle detection data of the actual tailplate unfolding angle. The power control module compares and analyzes the tailplate angle detection data with a preset tailplate angle threshold to generate angle comparison data, determining whether the tailplate unfolding state meets the power supply conditions. Based on the angle comparison data, the power control module triggers a power supply circuit control command to control the power supply circuit's on / off state. When the tailplate angle detection data is less than the preset tailplate angle threshold, a power supply circuit disconnect command is triggered to prevent accidental power supply when the tailplate is not fully unfolded. When the tailplate angle detection data is greater than or equal to the preset tailplate angle threshold, a power supply circuit connection command is triggered to ensure power supply when the tailplate is in an effective working posture.
[0130] Through the coordinated operation of the power-on / off circuit, undervoltage protection circuit, tilt switch and power control module, accurate generation of power management data is achieved, and a multi-dimensional collaborative power control closed loop is constructed.
[0131] By specifically collecting the flat posture of the tailboard through the power-on / off circuit, the system's working boundary is accurately defined, avoiding ineffective power supply when the tailboard is in a non-working state during transportation, thus reducing energy consumption. Through dual-condition collaborative detection in the power-on state, the system ensures power supply safety and adaptability from two core dimensions: power supply capacity and working posture, thereby improving the reliability of system operation.
[0132] By comparing the voltage detection and threshold values of the undervoltage protection circuit, the battery is effectively prevented from being damaged due to excessive discharge at low voltage, while also avoiding abnormal operation of the load equipment caused by low-voltage power supply. By comparing the angle detection and threshold values of the tilt switch, the power supply is ensured only when the tailplate is fully extended in its effective working posture, preventing accidental power supply when the tailplate is not extended or the extension angle is insufficient, thus reducing operational safety risks. Through clear threshold judgment logic and standardized power supply circuit control commands, the control logic is simplified, improving the accuracy and response speed of command execution. Through a multi-module collaborative closed-loop control design, intelligent and automated power supply management is achieved, reducing manual intervention.
[0133] In one embodiment of the present invention, S3 includes:
[0134] The microcontroller (MCU) controlling the warning light driver module generates warning light control commands based on power management data;
[0135] The LED driver circuit drives and controls the LED beads according to the warning light control instructions.
[0136] The working principle and technical effects of the above solution are as follows: The microcontroller (MCU) controlling the warning light driver module generates warning light control commands based on power management data, enhancing the flexibility and intelligence of the LED driver.
