[0048] EMBODIMENTS

[0049] As Figures 1-9The utility model provides a technical scheme: a bicycle tail light can display tire pressure warning, including bicycle main body, warning display tail light structure and two tire pressure detection components, the bicycle main body includes bicycle frame 1, seat connecting rod 2 and two tires 3 before and after, two tire pressure detection components are installed at two tires 3 before and after of the bicycle main body, the tire pressure detection component is used for real -time detection to the air pressure in tire 3, and the detection result is transmitted to the warning display tail light structure and is shown in real time and is blinked, the warning display tail light structure is installed at seat connecting rod 2 of the bicycle main body, the warning display tail light structure is used for real -time display the tire pressure condition of two tire 3, can blink and remind and show specific tire pressure value simultaneously.

[0050] The innovative design combines tire pressure monitoring with bicycle tail light functionality, forming a multifunctional safety warning system. As a common means of transportation, tire pressure has a crucial impact on the safety and comfort of cycling. Traditional bicycles often lack tire pressure monitoring functionality, making it difficult for cyclists to determine whether the tire pressure is appropriate. The utility model realizes active monitoring and visual reminders of tire pressure by setting tire pressure detection components and warning display tail light structures at key parts of the bicycle main body. The principle is to use the tire pressure detection component to sense the internal pressure of the tire, then transmit the data to the warning display tail light structure, so that the rider can directly see the pressure information and be alerted in case of abnormality, ensuring safety during cycling.

[0051] The tire pressure detection component includes a component housing 4, an internal valve core 5 is provided near the left side of the component housing 4, the valve core 5 is used for plug-in in the tire 3, the air pressure in the tire 3 can reach the component housing 4 through the valve core 5, and the tire 3 can be inflated and deflated through the valve core 5.

[0052] The component housing 4 provides protection and installation foundation for other components of the tire pressure detection component. The valve core 5 is a key connecting component between the tire 3 and the tire pressure detection component. Its design is ingenious in that it allows the air pressure in the tire 3 to enter the component housing 4, enabling subsequent pressure detection to proceed smoothly. On the other hand, it has a conventional valve function, allowing the rider to easily inflate the tire 3 using a pump or other tool through the valve core 5, or to deflate it when needed, maintaining the tire pressure within an appropriate range. This design follows the basic principles of traditional valve cores, with the addition of tire pressure detection-related functionality, maintaining the convenience of original tire maintenance operations while achieving the inlet function of pressure detection.

[0053] The tire pressure detection assembly further comprises a pressure sensor 6 installed on one side of the valve core 5, and air pressure can reach the pressure sensor 6 through the channel on one side of the valve core 5, and the pressure sensor 6 is used for real-time monitoring of the air pressure in the tire 3.

[0054] The pressure sensor 6 is one of the core components of the tire pressure detection assembly, and its working principle is based on the conversion relationship between pressure and electrical signals. When the air pressure in the tire 3 enters the assembly shell 4 through the valve core 5 and conducts to the pressure sensor 6, the pressure sensor 6 will generate corresponding electrical signal changes according to the pressure it receives. This change in electrical signal has a specific corresponding relationship with the air pressure value. For example, the higher the air pressure, the greater the electrical signal strength generated by the pressure sensor 6, or in some sensors, it is manifested as a change in physical quantities such as resistance value, capacitance value, etc. By collecting and analyzing these electrical signals, real-time air pressure data in the tire 3 can be accurately obtained, providing basic information for subsequent data transmission and processing.

[0055] The inside of the assembly shell 4 and at the right side is provided with a detection end main board 7, the detection end main board 7 is provided with a detection end analog-digital conversion module 8, a detection end microcontroller 9 and a detection end Bluetooth module 10, and the detection end main board 7 is connected with the pressure sensor 6 through wires, and the pressure sensor 6 transmits the collected pressure data to the detection end analog-digital conversion module 8 on the detection end main board 7.

[0056] The detection end main board 7 is the control and data processing center of the tire pressure detection assembly, and integrates multiple key modules. The detection end analog-digital conversion module 8 exists because the pressure data collected by the pressure sensor 6 is usually an analog signal, and the subsequent digital circuits such as microcontrollers can only process digital signals. The analog-digital conversion module uses specific circuit principles such as sampling, quantization and encoding to convert the continuous analog signal from the pressure sensor 6 into discrete digital signals, so that the data can be accurately read and processed by the detection end microcontroller 9. The detection end microcontroller 9 undertakes the task of analyzing and processing digital signals. It can perform data filtering operations to remove noise interference in the signal and improve data accuracy. It can also perform calibration operations to correct measurement data according to pre-set standard values, further ensuring the reliability of the data. The detection end Bluetooth module 10 is responsible for sending the processed data, and communicates wirelessly with the warning display tail lamp structure. It is based on Bluetooth wireless communication technology and sends data in a certain communication frequency band according to the Bluetooth protocol, realizing the remote transmission of tire pressure data.

[0057] The detection end analog-digital conversion module 8 is used for converting the analog signal collected by the pressure sensor 6 into a digital signal, so as to facilitate subsequent reading of the detection end microcontroller 9; the detection end microcontroller 9 is used for analyzing and processing the digital signal, performing data filtering, calibration and the like, so as to improve the accuracy and reliability of the data; the detection end Bluetooth module 10 is connected with the detection end microcontroller 9, when the information configuration of the detection end Bluetooth module 10 by the detection end microcontroller 9 is completed, the detection end Bluetooth module 10 sends information and waits for the receiving end of the warning display tail lamp structure to receive.

[0058] The detection end analog-digital conversion module 8 adopts common analog-digital conversion circuit technology, for example, successive approximation ADC or sigma-delta ADC, etc., these circuits convert the analog voltage or current signal output by the pressure sensor 6 into binary digital code through internal comparators, capacitor arrays or integrators and the like, according to certain timing and algorithm, so that the detection end microcontroller 9 can directly perform digital operation and logical judgment, in the data processing process of the detection end microcontroller 9, the data filtering can adopt digital filtering algorithm, such as mean filtering, median filtering and the like, through processing of adjacent data points or certain data sequence, the sudden interference and high frequency noise in the signal are smoothed, the calibration operation is to establish a calibration curve or mathematical model according to the known standard air pressure value and the corresponding sensor output signal relationship, and correct the actual measurement data, compensate the drift and non-linear error of the sensor, the detection end Bluetooth module 10 is configured under the detection end microcontroller 9, sets communication parameters such as Bluetooth address, pairing password, transmission rate and the like according to the communication specification of Bluetooth, then sends the processed tire pressure data in the form of Bluetooth data packet, while waiting for the response of the receiving end, maintains the connection state with the receiving end, ensures the stability and continuity of data transmission.

[0059] The warning display tail lamp structure comprises a structure shell 11, a warning end mainboard 12 is installed in the inside of the structure shell 11, a vibration sensor 13, a vibration wake-up module 14, a main control chip 15, a warning end Bluetooth module 16 and a charge management module 17 are installed on the warning end mainboard 12.

[0060] The structural shell 11 provides physical protection for the warning display tail light structure and mounting space for internal components. The warning end mainboard 12 serves as the core control board, integrating multiple functional modules to realize various functions of the system. The vibration sensor 13 is used to sense the vibration state of the bicycle. Its principle is based on the change of certain physical properties under the action of vibration, such as piezoelectric effect (piezoelectric vibration sensor 13) or capacitance change (capacitive vibration sensor 13). When the bicycle is subjected to vibration, the vibration sensor 13 generates corresponding changes in electrical signals. The vibration wake-up module 14 works in conjunction with the vibration sensor 13. Its role is to trigger the wake-up operation of the system only by relying on the weak electrical signal changes of the vibration sensor 13 when the bicycle is in a stationary or low-power state. The main control chip 15 serves as the control center of the entire warning display tail light structure, responsible for coordinating the workflow between various modules, such as receiving tire pressure data from the warning end Bluetooth module 16, controlling the display content and flashing mode of the color dot matrix display screen 18, etc.

[0061] The warning end Bluetooth module 16 is responsible for receiving tire pressure data sent by the detection end Bluetooth module 10 of the tire pressure detection assembly. It follows the same Bluetooth communication protocol as the detection end Bluetooth module 10, achieving bidirectional data transmission.

[0062] The charging management module 17 is responsible for precise management of the charging and discharging process of the battery 19. It monitors parameters such as voltage and current of the battery 19, controls the on-off of the charging circuit and the size of the charging current, to ensure safe charging and long service life of the battery 19. At the same time, according to the running state of the system, it provides appropriate power voltage for each module, realizing different power mode switching, such as switching the system to low-power sleep mode after the bicycle is stationary for a period of time to save power, and when the vibration sensor 13 detects vibration, the charging management module 17 cooperates with the main control chip 15 to wake up the system to enter normal working state.

[0063] The warning display tail light structure further comprises a color dot matrix display screen 18, a battery 19, a charging assembly 20, a first button 21 and a second button 22. The color dot matrix display screen 18 is installed on the front of the structural shell 11. The battery 19 is installed inside the structural shell 11. The charging assembly 20 is connected between the battery 19. The first button 21 and the second button 22 are connected between the warning end mainboard 12. The first button 21 and the second button 22 are used for adjusting the warning display tail light structure and other operations.

[0064] The color dot matrix display screen 18 is an important interface for displaying information to the rider. It can display the tire pressure value, tire pressure state (normal, too low) and various warning information in the form of graphics, text or specific patterns.

[0065] The working principle is based on the matrix arrangement and control technology of light emitting diode (LED), through the main control chip 15 to control the lighting and extinguishing state of each LED point accurately, different display contents are combined.

[0066] The battery 19 provides power support for the whole warning display tail light structure, ensures that each module can work normally when there is no external power supply access, and the charging component 20 realizes the charging function of the battery 19, for example, can adopt the form of USB charging interface or wireless charging module, etc., to transmit the power of external power supply to the battery 19 for storage.

[0067] The first button 21 and the second button 22 provide a human-computer interaction means for the rider, the rider can switch the display content through the button operation, such as viewing the tire pressure data of the front and rear tires 3, setting the tire pressure warning value, adjusting the display screen brightness, etc., these operation instructions are transmitted to the main control chip 15 through the circuit connection between the button and the warning end mainboard 12, and the main control chip 15 executes the corresponding function according to the preset program.

[0068] The vibration sensor 13 is used to accurately detect the vibration condition of the bicycle body and trigger the vibration wake-up module 14; the vibration wake-up module 14 is used to work with the main control chip 15, when the vibration sensor 13 detects vibration, an electrical signal change will be generated, after amplification, filtering and other processing, the signal is input to the interrupt pin of the main control chip 15 or connected with a comparator circuit, when the vibration signal exceeds the set threshold value, the main control chip 15 wakes up from the low-power sleep mode and enters the normal working state, ready to receive and process the air pressure data transmitted by the detection end Bluetooth module 10; the main control chip 15 is used to coordinate and control the components of the whole warning display tail light structure; the warning end Bluetooth module 16 is used to receive the signal from the detection end Bluetooth module 10 and transmit the signal to the main control chip 15; the charging management module 17 is used to manage the charging and discharging of the battery 19, including monitoring the battery 19 voltage, power, controlling the charging process, and distributing appropriate power voltage for each module in the system, it can realize multiple power modes, such as normal working mode, low-power sleep mode, etc., automatically adjust the power supply according to the running state of the device, in order to achieve the purpose of energy saving, when the battery 19 power is too low, the PMIC can send a low power signal to the main control chip 15, and the main control chip 15 triggers the color dot matrix display screen 18 to perform corresponding warning.

[0069] When the vibration sensor 13 detects the vibration of the bicycle, for example, the piezoelectric vibration sensor 13 uses the piezoelectric effect of the piezoelectric crystal, when it is subjected to vibration and produces mechanical stress, the crystal surface will generate electric charge and form an electrical signal.

[0070] The capacitive vibration sensor 13 generates an electric signal by changing the distance or area between the capacitor plates caused by vibration, and the vibration wake-up module 14 amplifies the weak electric signal from the vibration sensor 13, and uses an amplifier circuit to improve the signal amplitude, so that the subsequent circuit can accurately identify.

[0071] The filter processing removes the stray interference in the signal, such as using a low-pass filter to remove high-frequency noise. The processed signal is connected to the interrupt pin of the main control chip 15 or connected to the comparator circuit. The comparator compares the signal with the set threshold voltage. When the signal exceeds the threshold, the interrupt of the main control chip 15 is triggered, which wakes up from the low-power sleep mode.

[0072] In the normal working state, the main control chip 15 coordinates the work of each module according to the preset program logic, for example, controls the warning end Bluetooth module 16 to periodically scan and connect the detection end Bluetooth module 10, receives the tire pressure data, and performs data analysis and processing. According to the processing result, the display content and flicker mode of the color dot matrix display screen 18 are determined.

[0073] When the warning end Bluetooth module 16 receives data, it performs operations such as data unpacking and checking according to the Bluetooth communication protocol, and transmits the data to the main control chip 15 after ensuring the integrity and correctness of the data. When monitoring the voltage and capacity of the battery 19, the charging management module 17 uses voltage dividing circuit and capacity measurement chip technology to obtain the state information of the battery 19 in real time.

[0074] During the control of the charging process, the charging current and voltage are adjusted by the charging control chip, for example, the constant current-

[0075] The constant voltage charging mode first charges with a constant current, and then charges with a constant voltage when the voltage of the battery 19 reaches the set value, ensuring the safety and efficiency of the battery 19 charging.

[0076] When implementing multiple power supply modes, the power supply switch tube or power management chip of each module is controlled to switch between different working modes, such as in the low-power sleep mode, the power of unnecessary modules is turned off or the working frequency is reduced to reduce power consumption. When the battery 19 is low, the power management chip (PMIC) in the charging management module 17 sends a low power signal to the main control chip 15, and the main control chip 15 controls the color dot matrix display screen 18 to display a low power warning icon or text according to the signal, reminding the rider to charge in time.

[0077] The color dot matrix display screen 18 can display different pictures according to the information transmitted by the main control chip 15, and transmit different warning information to the user.

[0078] The display control of the color dot matrix display screen 18 is based on the instruction operation of the main control chip 15 on its internal display driver chip. The main control chip 15 generates corresponding display instruction codes according to the received tire pressure data and system status information. These instruction codes are transmitted to the driver chip of the color dot matrix display screen 18 through the data bus. The driver chip controls the parameters such as the light emission color, brightness and lighting time of each LED dot on the display screen according to the instructions.

[0079] like Figure 10 As shown, when the pressure of both tires is sufficient, it indicates that the vehicle is ready to be ridden. At this time, the color dot matrix display screen 18 flashes a green light every 0.5 seconds, and this is repeated three times.

[0080] When the pressure of both tires is insufficient, it indicates that it is safe to ride a short distance or in a safe condition. At this time, the color dot matrix display screen 18 will flash a circle of yellow lights every 0.5 seconds, and this will be done three times in total.

[0081] When the pressure of both tires (3 tires) is severely insufficient, it indicates that riding is not possible. At this time, the color dot matrix display screen 18 will flash a red light every 0.5 seconds, for a total of 3 times.

[0082] like Figure 11 As shown, tire A 3 (displayed as A on the left side of the color dot matrix display screen 18 at this time; in this application, tire A 3 is the front tire 3) has sufficient tire pressure, while tire B 3 (displayed as B on the right side of the color dot matrix display screen 18 at this time; in this application, tire B 3 is the rear tire 3) has insufficient tire pressure. This indicates that the vehicle is ready for riding. At this time, the color dot matrix display screen 18 will display A in green and B in yellow, flashing once every 0.5 seconds, for a total of 3 times.

[0083] If tire A (tire 3) has insufficient pressure and tire B (tire 3) has sufficient pressure, it indicates that the vehicle can be ridden for a short distance or in a safe condition. At this time, the color dot matrix display screen 18 will show yellow for tire A and green for tire B, flashing once every 0.5 seconds for a total of 3 times.

[0084] like Figure 12 As shown, when tire A (tire 3) is severely deflated and tire B (tire 3) is inflated, it indicates that riding is not allowed. At this time, the color dot matrix display screen 18 will show A in red and B in green, flashing once every 0.5 seconds, for a total of 3 times.

[0085] If tire A (tire 3) is severely deficient in pressure and tire B (tire 3) is also underinflated, it indicates that riding is not permitted. At this time, the color dot matrix display screen 18 will show A in red and B in yellow, flashing once every 0.5 seconds, for a total of 3 times.

[0086] likeFigure 13 As shown, when the tire pressure of B tire 3 is seriously insufficient, and the tire pressure of A tire 3 is sufficient, at this time, the state is unable to ride, at this time, the color dot matrix display screen 18 will be displayed as A green, B red, flashing once every 0.5s, a total of three times 3 times;

[0087] If the tire pressure of B tire 3 is seriously insufficient, and the tire pressure of A tire 3 is insufficient, at this time, the state is unable to ride, at this time, the color dot matrix display screen 18 will be displayed as A yellow, B red, flashing once every 0.5s, a total of three times 3 times.

[0088] As shown, at this time, the color dot matrix display screen 18 will display various patterns, and the user can select the corresponding pattern according to his own preference, at this time, it means warning the rear vehicle. Figure 14 As shown, when the tire pressure needs to be actively checked, only the second button 22 needs to be actively pressed, at this time, the color dot matrix display screen 18 will display the specific tire pressure value as shown.

[0089] Figure 15 As shown, when the tire pressure needs to be actively checked, only the second button 22 needs to be actively pressed, at this time, the color dot matrix display screen 18 will display the specific tire pressure value as shown.

[0090] In actual use, the valve core 5 in the tire pressure detection assembly is connected with the bicycle tire 3, and the air pressure in the tire 3 enters the assembly shell 4 through the valve core 5, and reaches the pressure sensor 6.

[0091] The pressure sensor 6 converts the air pressure into an analog electric signal and transmits it to the detection end analog-digital conversion module 8 on the detection end mainboard 7.

[0092] After the detection end analog-digital conversion module 8 converts the analog signal into a digital signal, the detection end microcontroller 9 processes the digital signal for data filtering, calibration, etc., to ensure data accuracy and reliability.

[0093] The processed tire pressure data is sent out by the detection end Bluetooth module 10.

[0094] The warning end Bluetooth module 16 in the warning display tail light structure receives the tire pressure data from the detection end Bluetooth module 10 and transmits it to the main control chip 15.

[0095] When the bicycle is in a static or low-power state, the vibration sensor 13 detects the vibration of the bicycle, generates an electric signal change, and after processing by the vibration wake-up module 14, if the vibration signal exceeds the set threshold, the main control chip 15 wakes up from the low-power sleep mode to enter the normal working state, and is ready to receive and process the tire pressure data.

[0096] The main control chip 15 controls the color dot matrix display screen 18 to display the corresponding picture according to the received tire pressure data, such as normal tire pressure value display, abnormal tire pressure warning (displaying a specific flashing mode and warning information when too high or too low). ​

[0097] The charging management module 17 continuously monitors the battery 19 voltage, power, controls the charging process when charging, distributes appropriate power supply voltage for each module of the system, and sends a low power signal to the main control chip 15 when the battery 19 power is too low. The main control chip 15 triggers the color dot matrix display screen 18 to display a low power warning. The rider can also adjust the warning display tail light structure through the first button 21 and the second button 22, such as checking different tire 3 tire pressure, setting a warning value, etc.

[0098] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
