Description

Technical Field

[0001] The present application relates to the technical field of intelligent turn signal lamps, and in particular to an intelligent turn signal lamp system for bicycles. Background Art

[0002] With the continuous development of intelligent transportation, the intelligence level of bicycles is also gradually improving. At present, there are some bicycle turn signal systems on the market. When using them, the rider is usually required to manually turn on or off the turn signal before preparing to turn, so as to inform the surrounding vehicles or pedestrians of their turning intention. However, this manual operation method sometimes causes the turn signal to be untimely or inaccurate due to the rider's negligence or inconvenient operation, which poses certain safety hazards. Utility Model Content

[0003] In order to improve the problem of untimely or inaccurate turn signals due to rider negligence or inconvenient operation in manual operation, the present application provides an intelligent turn signal system for a bicycle.

[0004] The present application provides a bicycle intelligent turn signal system using the following technical solutions:

[0005] A smart steering light system for a bicycle comprises a light assembly, a sensor assembly arranged in handlebars on both sides, and a smart terminal, wherein the light assembly comprises a pair of headlights facing the front of the bicycle and a pair of taillights facing the rear of the bicycle, and the sensor assembly comprises a gyroscope and a magnetometer; the headlights, the taillights, the warning lights, the gyroscope, and the magnetometer are all connected to the smart terminal by signal; the bicycle steering light system further comprises:

[0006] A manual control module, used for manually controlling the turning on or off of the vehicle headlights and the vehicle taillights;

[0007] A data processing module, used to obtain the angular velocity data collected by the gyroscope and the vehicle head direction measured by the magnetometer, and determine the inclination of the handlebar according to the angular velocity data and the vehicle head direction;

[0008] The automatic control module is used to control the turning on or off of the headlights and the taillights according to the handlebar tilt in the data processing module.

[0009] By adopting the above technical solution, during the driving of the bicycle, the rider can manually control the opening and closing of the headlights and taillights through the manual control module before turning to remind others of the turning intention. The intelligent turn signal system of the present application can also be used when the rider forgets or other unexpected circumstances lead to neglecting to turn on the turn signal by hand. The data processing module first obtains the angular velocity data and the direction of the front of the vehicle, and judges the inclination of the handlebar according to the preset calculation method, and then the automatic control module automatically controls the opening and closing of the headlights and taillights according to the inclination of the handlebar; thus, the present application can give a timely turn signal to surrounding vehicles or pedestrians every time the rider turns, effectively reducing the traffic accidents caused by the vehicle failing to give a turn signal in time when turning, and greatly ensuring the safety of the rider and other people in the traffic.

[0010] In a specific feasible implementation scheme, the lighting assembly includes two warning lights respectively arranged on both sides of the bicycle body, the sensor assembly also includes a number of distance sensors arranged around the bicycle, and the warning lights and the distance sensors are both signal-connected to the smart terminal; the data processing module is also used to obtain the real-time distance between other vehicles or pedestrians and the bicycle collected by the distance sensor and obtain a collision prediction result based on the real-time distance and the acceleration data, and the automatic control module is also used to control the turning on or off of the warning lights based on the collision prediction result.

[0011] By adopting the above technical solution, the distance sensor arranged on the bicycle body can detect the real-time distance between other vehicles and the bicycle itself, and the accelerometer can collect the acceleration value of the bicycle itself in real time. Therefore, the data processing module can obtain the collision prediction result according to the real-time distance and acceleration value, and the automatic control module can alert the oncoming vehicle or pedestrian by controlling the light corresponding to the direction of the oncoming vehicle or pedestrian to turn on before the vehicle or pedestrian may collide with the bicycle due to not noticing the bicycle.

[0012] In a specific possible implementation scheme, the sensor assembly also includes an accelerometer provided in the handlebars on both sides, the accelerometer is signal-connected to the smart terminal, the data processing module is also used to obtain the acceleration data collected by the accelerometer and determine the vehicle deceleration condition based on the acceleration data, and the automatic control module is also used to control the turning on or off of the warning light and the tail light according to the vehicle deceleration condition.

[0013] By adopting the above technical solution, the data processing module can obtain the situation that the vehicle suddenly stops or slowly decelerates when the acceleration suddenly drops rapidly or slowly, and then the automatic control module controls the opening and closing of the warning lights and tail lights according to the above-mentioned vehicle deceleration situation; thus, the intelligent turn signal system of the present application can promptly give a warning light signal to the vehicles behind and oncoming from the side when the bicycle stops suddenly.

[0014] In a specific possible implementation, the sensor assembly also includes a positioning sensor provided on the bicycle body, and the positioning sensor is signal-connected to the smart terminal; the data processing module is also used to obtain the vehicle position information collected by the positioning sensor and obtain a predicted turning result based on the vehicle position information and a preset navigation route; the automatic control module is also used to control the turning on or off of the headlights and the taillights according to the predicted turning result.

[0015] By adopting the above technical solution, the data processing module can obtain the predicted turning result according to the vehicle position information and the navigation route. Therefore, when the bicycle is about to turn, the automatic control module can control the opening and closing of the headlights and taillights according to the predicted turning result. The rider no longer needs to be distracted by controlling the opening and closing of the headlights and taillights while following the navigation, thereby effectively ensuring the safety of the rider.

[0016] In a specific implementation scheme, the bicycle guide light system further includes:

[0017] A true or false judgment module stores a preset time threshold and is used to judge the authenticity of the handlebar tilt according to the time threshold;

[0018] The automatic control module is also used to control the turning on or off of the headlights and the taillights according to the tilt of the handlebar when the judgment result in the true or false judgment module is true.

[0019] By adopting the above technical solution, when a bicycle is moving straight normally, if a vehicle suddenly appears in front of it to go in the opposite direction or topples over, the handlebars of the bicycle will briefly tilt when avoiding the vehicle in front. This handlebar tilt will resume straight movement in a short time, but it is extremely easy to cause misjudgment of the automatic control module in the intelligent turn signal system at the moment it occurs; therefore, the true or false judgment module provided in the present application can first judge the authenticity of the handlebar tilt of the bicycle according to a preset time threshold, and then the automatic control module controls the opening and closing of the corresponding headlights and taillights when the handlebar tilt is true, thereby effectively improving the accuracy of the intelligent control turn signals (headlights and taillights), thereby reducing the interference caused by the erroneous opening of the turn signals to surrounding vehicles or pedestrians.

[0020] In a specific possible implementation scheme, it also includes a power supply component for providing electrical energy to the sensor component, the smart terminal and the turn signal component.

[0021] In a specific implementation manner, the power supply assembly includes a rechargeable battery and a charging interface for charging the rechargeable battery, and the charging interface is disposed on the bicycle.

[0022] By adopting the above technical solution, the intelligent turn signal system of the present application can ensure normal use during daily charging.

[0023] In a specific implementation scheme, the intelligent terminal further includes a function test module for automatically detecting the communication status between the data processing module and the automatic control module.

[0024] By adopting the above technical solution, the functional testing module of the present application can test the automatic control lighting (warning, headlights and taillights) function of the intelligent turn signal system by sending test signals and receiving feedback before or during riding, so as to ensure that the rider can promptly discover and take measures when the automatic lighting control function fails, thereby greatly improving safety.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. This application realizes automatic detection of handlebar tilt, effectively reducing traffic accidents caused by the vehicle's failure to give a turn signal in time when turning, and greatly ensuring the safety of riders and other people in traffic.

[0027] 2. The true or false judgment module set in this application can effectively improve the accuracy of intelligent control of turn signals (headlights and taillights), thereby reducing the interference caused by the wrong turn signal to surrounding vehicles or pedestrians;

[0028] 3. This application uses a variety of sensors, such as gyroscopes, magnetometers, distance sensors, accelerometers and positioning sensors, to obtain richer riding data, such as angular velocity, vehicle head direction, real-time distance, acceleration and vehicle position, so as to make more comprehensive safety judgments and controls, further improving the practicality and safety of the intelligent turn signal system.

[0032] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0033] Embodiment 1 of the present application discloses an intelligent turn signal system for a bicycle.

[0034] Reference Figure 1 A smart turn signal system for a bicycle includes a light assembly, a sensor assembly, and a smart terminal. The light assembly includes a pair of headlights facing the front of the bicycle and a pair of taillights facing the rear of the bicycle. The headlights and taillights of this embodiment each include two left and right LED lights. During riding, this embodiment sends a turn signal by flashing the two LED lights on the side of the headlight and taillight corresponding to the turning direction to inform the surrounding vehicles or pedestrians of the rider's turning intention.

[0035] Reference Figure 1 The sensor components are located in the handlebars on both sides, mainly including gyroscopes and magnetometers. The gyroscope is used to collect the angular velocity data of the handlebars, while the magnetometer is used to measure the direction of the front of the vehicle. These two sensors work together to accurately determine the tilt of the handlebars, thereby reflecting the rider's steering intention.

[0036] Reference Figure 1 ,The intelligent terminal is the core part of this system. It receives and processes data from the sensor components and controls the working state of the lighting components based on these data. Specifically, the intelligent terminal mainly includes a manual control module, a data processing module and an automatic control module. The manual control module allows the rider to manually control the opening or closing of the headlights and taillights when necessary. The data processing module is responsible for acquiring and processing the data collected by the sensor components, such as angular velocity data and vehicle head direction data, and judging the handlebar inclination based on these data. The automatic control module automatically controls the opening or closing of the headlights and taillights according to the judgment results of the data processing module, thereby realizing the automatic sending of turn signals.

[0037] In this embodiment, the data processing module mainly calculates the current posture angle of the bicycle according to the angular velocity data and the direction of the front of the bicycle, so as to determine whether the bicycle needs to turn. This calculation method is a prior art and will not be described in detail here.

[0038] The implementation principle of Example 1 is as follows: during riding, the sensor assembly continuously collects the angular velocity data of the handlebars and the direction data of the front of the vehicle, and sends these data to the smart terminal in real time. After receiving these data, the data processing module of the smart terminal determines the inclination of the handlebars, that is, the rider's turning intention, through a preset algorithm. When it is determined that the traveler has a turning intention, the automatic control module will immediately control the corresponding headlights or taillights to turn on and send out a turn signal. In this way, the turn signal can be sent out in a timely and accurate manner without the need for manual operation by the rider, which greatly improves the safety of riding.

[0039] Example 2

[0040] Reference Figure 1 The difference of this embodiment is that the sensor assembly is further provided with a plurality of distance sensors arranged around the bicycle body, and two warning lights respectively arranged on both sides of the bicycle body.

[0041] In this embodiment, the distance sensors are installed at the front, rear and both sides of the bicycle, respectively, and are used to collect the real-time distance between other vehicles or pedestrians and the bicycle in the four directions of the front, rear, left and right of the bicycle.

[0042] In addition to processing the angular velocity data and the vehicle head direction data, the data processing module also obtains the real-time distance data collected by the distance sensor, and performs collision prediction based on these data and a preset algorithm. In this embodiment, the data processing module mainly obtains the collision prediction result of a possible collision when the real-time distance data is continuously reduced in a short period of time. At this time, the warning lights, headlights and taillights on both sides of the bicycle body will continuously flash under the control of the automatic control module to send out warning signals to remind surrounding vehicles and pedestrians to pay attention to safety.

[0043] In addition, the sensor assembly also includes an accelerometer disposed in the handlebars on both sides, and the acceleration data collected by the accelerometer can reflect the deceleration of the vehicle. When the data processing module detects that the vehicle is decelerating, the automatic control module will control the warning light and the tail light to turn on accordingly to remind the vehicles behind to keep a safe distance. In this embodiment, when the bicycle stops suddenly, the warning light and the tail light flash quickly, and when the bicycle slows down slowly, the warning light and the tail light stay on until the bicycle stops or starts to accelerate again.

[0044] Reference Figure 2, the smart terminal of this embodiment takes the processor ESP32 as an example, which supports Bluetooth and Wi-Fi communication, and also has electronic components such as integrated circuit bus I2C, serial peripheral interface SPI, general input and output GPIO interface and universal asynchronous receiver and transmitter UART, analog digital converter ADC, etc. Among them, C8 and C9 are power supply filter capacitors; IO13 is GPIO interrupt input mode, which is used to determine whether to obtain updated data in the sensor component (gyroscope, accelerometer and magnetometer); IO18 and IO19 are I2C mode, which is used to communicate with the gyroscope, accelerometer and magnetometer in the sensor component; IO16 is GPIO interrupt input mode, which is used to determine whether to synchronize the collected data with the stored data, so as to ensure the timeliness and effectiveness of the collected data (angular velocity data, vehicle head direction and acceleration data).

[0045] Reference Figure 3 The sensor component of this embodiment takes MPU9250 as an example. The sensor integrates an angular velocity meter, an accelerometer and a magnetometer. The communication mode is I2C and SPI. MPU9250 can be configured through I2C to output a pulse signal mode on the INT pin after updating data.

[0046] Example 3

[0047] The difference of this embodiment is that a positioning sensor and a true or false judgment module are added. The positioning sensor is arranged on the bicycle body and is used to collect the position information of the vehicle. The data processing module, combined with the preset navigation route, can predict the rider's turning intention according to the vehicle position information and obtain the turning prediction result, so as to control the turning on or off of the headlights and taillights in advance.

[0048] The authenticity judgment module is used to judge the authenticity of the handlebar tilt. It stores a preset time threshold. When the handlebar tilt lasts longer than the time threshold, it is considered a valid steering operation. This design is to avoid the turn signal being triggered by mistake due to a short handlebar shake caused by misoperation or avoiding the vehicle in front. Only when the authenticity judgment module confirms that the handlebar tilt is a real and valid steering intention, the automatic control module will control the corresponding light components to turn on or off according to the tilt.

[0049] Example 4

[0050] The present embodiment discloses a power supply assembly for providing power to the sensor assembly, the intelligent terminal and the turn signal assembly. The power supply assembly includes a rechargeable battery and a charging interface, which is conveniently arranged on the bicycle so that the rider can charge the battery at any time when needed, thereby ensuring the continuous and stable operation of the intelligent turn signal system.

[0051] It should be noted that in all the above embodiments, the manual control module and the automatic control module realize the switching of the lights by sending control commands (opening and closing the switches in the control circuit) to all the lights in the light assembly, wherein the control command sent by the automatic control module has a higher priority than the control command sent by the manual control module, and the control command issued according to the handlebar inclination has a higher priority than the control command issued according to the steering prediction result; that is, when the turn signal manually controlled by the rider (the LED lights corresponding to the steering direction in the headlights and taillights) is inconsistent with the automatically controlled turn signal, the control command issued by the manual control module will be cancelled, and the automatically controlled turn signal will be turned on accordingly, so that the control command obtained according to the actual vehicle body inclination is more accurate, effectively reducing the execution of the control command given by the rider in error;

[0052] Similarly, when the rider does not follow the navigation, the intelligent turn signal system of the present application will not issue an erroneous turn prompt based on the turn prediction result, but will control the LED lights in the correct direction to send out turn signals based on the actual vehicle body inclination, thereby greatly improving the accuracy of the turn signal issued by the intelligent turn signal system.

[0053] Example 5

[0054] Reference Figure 1 , the difference of this embodiment is that the intelligent turn signal system also includes a function test module for automatically detecting the communication status between the data processing module and the automatic control module, which is responsible for real-time monitoring of the communication status between the data processing module and the automatic control module to ensure accurate data transmission and normal operation of the module. During bicycle riding, the communication line may become unstable or fail due to vibration, environmental factors or equipment aging. The function test module detects the smoothness of communication by regularly sending test signals and receiving feedback.

[0055] Once a communication anomaly is detected, the functional test module will immediately trigger an alarm mechanism, prompting the rider to perform maintenance through sound, light or other means. At the same time, it can also try to restart the communication link or switch to a backup communication channel to ensure the continuous operation of the system. This design not only improves the stability of the system, but also further enhances the safety of riders in complex traffic environments.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
