Description

Technical Field

[0001] The invention relates to the technical field of bicycle tire pressure monitoring, and in particular to a bicycle taillight capable of displaying tire pressure warning. Background Art

[0002] With the acceleration of urbanization and people's pursuit of healthy life, bicycles are used more and more frequently as a green and low-carbon means of travel. Whether it is urban commuting, outdoor sports or leisure riding, bicycles are widely used in various fields.

[0003] During the use of bicycles, tire pressure is one of the key factors to ensure riding safety and comfort. Normal tire pressure can ensure good contact between the tire and the ground, and ensure riding stability and controllability. However, insufficient or excessive tire pressure often occurs. Insufficient tire pressure may be caused by slow tire leakage, valve core failure and other reasons, which will increase the friction between the tire and the ground, making riding more laborious and accelerating tire wear. What is more serious is that in this case, the heat generated by the tire during driving is difficult to dissipate effectively, increasing the possibility of tire blowout. If the tire pressure is too high, the contact area of ​​the tire will be reduced, reducing the stability of riding, especially on slippery roads or turning, which can easily cause the vehicle to lose control.

[0004] As an important accessory to ensure cycling safety, bicycle taillights play a key role at night or in low visibility environments. However, the main function of existing bicycle taillights on the market is to warn vehicles behind by emitting light. Their design and functions are relatively simple. Although some taillights have been improved in terms of brightness and flashing mode, they have not been combined with the important safety function of tire pressure monitoring, and have failed to give full play to the potential of taillights as a core component of bicycle safety warnings. This situation has resulted in cyclists lacking a simple, direct and integrated way to simultaneously obtain vehicle warning information and abnormal tire pressure information during riding.

[0005] Therefore, we propose a bicycle taillight that can display tire pressure warning. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings existing in the prior art. As an important accessory to ensure riding safety, bicycle taillights play a key role at night or in low visibility environments. The main function of existing bicycle taillights on the market is to warn vehicles behind by emitting light. Their design and functions are relatively simple. Although some taillights have been improved in terms of brightness, flashing mode, etc., they are not combined with the important safety function of tire pressure monitoring, and the potential of taillights as core components of bicycle safety warnings has not been fully utilized. This situation results in the lack of a simple, direct and integrated way for riders to simultaneously obtain vehicle warning information and abnormal tire pressure information during riding.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A bicycle taillight capable of displaying tire pressure warning comprises a bicycle body, a warning display taillight structure and two tire pressure detection components.

[0009] The bicycle body comprises a bicycle frame, a seat connecting rod and two front and rear tires.

[0010] Two tire pressure detection components are installed at the front and rear tires of the bicycle body. The tire pressure detection components are used to detect the air pressure in the tires in real time and transmit the detection results to the warning display taillight structure for real-time display and flashing.

[0011] The warning display taillight structure is installed at the seat connecting rod of the bicycle body. The warning display taillight structure is used to display the air pressure of the two tires in real time, and can flash to remind and display the specific tire pressure value.

[0012] As a preferred solution of the present invention, the tire pressure detection component includes a component housing, and a valve core is provided inside the component housing and near the left side. The valve core is used to be inserted into the tire. The air pressure in the tire can reach the component housing through the valve core, and the tire can be flushed and deflated through the valve core.

[0013] As a preferred solution of the present invention, the tire pressure detection assembly also includes a pressure sensor, which is installed on one side of the valve core. The air pressure can reach the pressure sensor through one side of the valve core. The pressure sensor is used to monitor the air pressure in the tire in real time.

[0014] As a preferred solution of the present invention, a detection end mainboard is provided inside the component housing and on the right side, and a detection end analog-to-digital conversion module, a detection end microcontroller and a detection end Bluetooth module are installed on the detection end mainboard.

[0016] The detection end microcontroller is used to analyze and process digital signals, perform data filtering, calibration and other operations to improve the accuracy and reliability of data;

[0017] The detection end Bluetooth module is connected to the detection end microcontroller.

[0020] As a preferred solution of the present invention, the vibration sensor is used to accurately detect the vibration of the bicycle body and trigger the vibration wake-up module;

[0021] The vibration wake-up module is used to work in conjunction with the main control chip. When the vibration sensor detects vibration, an electrical signal change is generated.

It can realize multiple power supply modes, such as normal working mode, low-power sleep mode, etc., and automatically adjust the power supply according to the operating status of the equipment to achieve the purpose of energy saving. When the battery power is too low, the PMIC can send a low power signal to the main control chip, and the main control chip triggers the color dot matrix display screen to issue a corresponding warning.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] Example

[0049] like Figure 1-9 As shown, the present invention provides a technical solution: a bicycle taillight capable of displaying tire pressure warning, comprising a bicycle body, a warning display taillight structure and two tire pressure detection components, wherein the bicycle body comprises a bicycle frame 1, a seat connecting rod 2 and two front and rear tires 3, and the two tire pressure detection components are installed at the two front and rear tires 3 of the bicycle body, and the tire pressure detection components are used to perform real-time detection of the air pressure in the tires 3, and transmit the detection results to the warning display taillight structure for real-time display and flashing, and the warning display taillight structure is installed at the seat connecting rod 2 of the bicycle body, and the warning display taillight structure is used to display the tire 3 air pressure conditions of the two tires 3 in real time, and can flash to remind and display specific tire pressure values.

[0050] This innovative design combines tire pressure monitoring with the bicycle taillight function to form a multifunctional safety warning system. As a common means of transportation, the tire 3 air pressure of bicycles has a vital impact on riding safety and comfort. Traditional bicycles often lack tire pressure monitoring functions, and it is difficult for riders to know whether the tire 3 air pressure is appropriate. The present invention realizes active monitoring and visual reminder of the tire 3 air pressure by arranging tire pressure detection components and warning display taillight structures at key positions of the bicycle body. The principle is to use the tire pressure detection component to sense the internal air pressure of the tire 3, and then transmit the data to the warning display taillight structure, so that the rider can intuitively see the air pressure information and get a warning in case of abnormalities, thereby ensuring safety during riding.

[0051] The tire pressure detection component includes a component housing 4, and a valve core 5 is provided inside the component housing 4 and near the left side. The valve core 5 is used to be inserted into 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 flushed and deflated through the valve core 5.

[0052] The component housing 4 provides protection and installation basis 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 clever in that, on the one hand, it allows the air pressure in the tire 3 to enter the interior of the component housing 4, so that subsequent pressure detection can be carried out smoothly. On the other hand, its conventional valve function allows the rider to still conveniently use tools such as an air pump to inflate the tire 3 through the valve core 5, or deflate it when necessary, to keep the tire 3 pressure within an appropriate range. This design follows the basic principle of the traditional valve core 5, but adds functional expansion related to tire pressure detection on this basis, which does not affect the convenience of the original tire 3 maintenance operation, and realizes the entrance function of air pressure detection.

[0053] The tire pressure detection component also includes a pressure sensor 6, which is installed on one side of the valve core 5. The air pressure can reach the pressure sensor 6 through a channel on one side of the valve core 5. The pressure sensor 6 is used to monitor the air pressure in the tire 3 in real time.

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

[0055] A detection end mainboard 7 is provided inside the component housing 4 and on the right side. A detection end analog-to-digital conversion module 8, a detection end microcontroller 9 and a detection end Bluetooth module 10 are installed on the detection end mainboard 7. The detection end mainboard 7 is also connected to the pressure sensor 6 through a wire. The pressure sensor 6 transmits the collected pressure data to the detection end analog-to-digital conversion module 8 on the detection end mainboard 7.

[0056] The detection end mainboard 7 serves as the control and data processing center of the tire pressure detection component and integrates multiple key modules. The detection end analog-to-digital conversion module 8 exists because the pressure data collected by the pressure sensor 6 is usually an analog signal, and subsequent digital circuits such as microcontrollers can only process digital signals. The analog-to-digital conversion module uses specific circuit principles, such as sampling, quantization and encoding operations, to convert the continuous analog signal transmitted by the pressure sensor 6 into a discrete digital signal, so that the data can be accurately read and processed by the detection end microcontroller 9. The detection end microcontroller 9 is responsible for 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 the measured data according to pre-set standard values ​​to further ensure data reliability. The detection end Bluetooth module 10 is responsible for sending the processed data and wirelessly communicating with the warning display taillight structure. It is based on Bluetooth wireless communication technology and packages and sends data in a certain communication frequency band according to the Bluetooth protocol to achieve remote transmission of tire pressure data.

[0057] The detection end analog-to-digital conversion module 8 is used to convert the analog signal collected by the pressure sensor 6 into a digital signal, so as to facilitate the subsequent reading by the detection end microcontroller 9; the detection end microcontroller 9 is used to analyze and process the digital signal, and perform data filtering, calibration and other operations to improve the accuracy and reliability of the data; the detection end Bluetooth module 10 is connected to the detection end microcontroller 9. When the detection end microcontroller 9 completes the information configuration of the detection end Bluetooth module 10, the detection end Bluetooth module 10 sends the information and waits for the receiving end of the warning display taillight structure to receive it.

[0058] The detection end analog-to-digital conversion module 8 adopts common analog-to-digital conversion circuit technology, such as 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 other components according to a certain timing and algorithm, so that the detection end microcontroller 9 can directly perform digital operations and logical judgments. During the data processing process, the detection end microcontroller 9 can use digital filtering algorithms for data filtering, such as mean filtering, median filtering, etc., by processing adjacent data points or a certain data sequence. , smooth out the sudden interference and high-frequency noise in the signal. The calibration operation is based on the known standard air pressure value and the corresponding sensor output signal relationship to establish a calibration curve or mathematical model, correct the actual measurement data, and compensate for the drift and nonlinear error of the sensor. The detection end Bluetooth module 10, under the configuration of the detection end microcontroller 9, sets the communication parameters such as Bluetooth address, pairing password, transmission rate, etc. in accordance with the Bluetooth communication specification, and then sends the processed tire pressure data in the form of a Bluetooth data packet. While waiting for the response from the receiving end, maintain the connection status with the receiving end to ensure the stability and continuity of data transmission.

[0059] The warning display taillight structure includes a structural shell 11, a warning end mainboard 12 is installed inside the structural shell 11, and a vibration sensor 13, a vibration wake-up module 14, a main control chip 15, a warning end Bluetooth module 16 and a charging management module 17 are installed on the warning end mainboard 12.

[0060] The structural shell 11 provides physical protection for the warning display taillight structure and installation space for internal components. The warning end mainboard 12 serves as a core control board and integrates multiple functional modules to realize multiple 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 the piezoelectric effect (piezoelectric vibration sensor 13) or capacitance change (capacitive vibration sensor 13). When the bicycle is vibrated, the vibration sensor 13 will produce corresponding electrical signal changes. The vibration wake-up module 14 works in conjunction with the vibration sensor 13. Its function is to trigger the system wake-up operation 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 taillight structure and is responsible for coordinating the work processes between various modules, such as receiving tire pressure data transmitted by the warning end Bluetooth module 16, and controlling the display content and flashing mode of the color dot matrix display screen 18.

[0061] The warning end Bluetooth module 16 is responsible for receiving the tire pressure data sent from the detection end Bluetooth module 10 of the tire pressure detection component. It follows the same Bluetooth communication protocol as the detection end Bluetooth module 10 to achieve two-way data transmission.

[0062] The charging management module 17 is responsible for the precise management of the charging and discharging process of the battery 19. It controls the on and off of the charging circuit and the size of the charging current by monitoring the voltage, current and other parameters of the battery 19 to ensure the safe charging and long life of the battery 19. At the same time, according to the operating status of the system, it allocates appropriate power supply voltage to each module to achieve different power mode switching. For example, after the bicycle has been stationary for a period of time, the system is switched to a low-power sleep mode to save power. When the vibration sensor 13 detects vibration, the charging management module 17 cooperates with the main control chip 15 to wake up the system and put it into normal working state.

[0063] The warning display taillight structure also includes a color dot matrix display screen 18, a battery 19, a charging component 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, and the battery 19 is installed inside the structural shell 11. The charging component 20 and the battery 19 are interconnected, and the first button 21 and the second button 22 are interconnected with the warning end mainboard 12. The first button 21 and the second button 22 are used to adjust the warning display taillight structure and perform other operations.

[0064] The color dot matrix display screen 18 is an important interface for displaying information to the rider. It can display the air pressure value of the tire 3, the tire pressure status (normal, too low) and various warning messages in the form of graphics, text or specific patterns.

[0065] Its working principle is based on the matrix arrangement and control technology of light emitting diodes (LEDs). The main control chip 15 accurately controls the lighting and extinguishing status of each LED point to combine different display contents.

[0066] The battery 19 provides power support for the entire warning display taillight structure, ensuring that each module can work normally when there is no external power supply. The charging component 20 realizes the charging function of the battery 19. For example, a USB charging interface or a wireless charging module can be used to transfer the power of the external power supply to the battery 19 for storage.

[0067] The first button 21 and the second button 22 provide a means of human-computer interaction for the rider. The rider can switch the display content by button operation, such as checking the tire pressure data of the front and rear tires 3, setting the tire pressure warning value, adjusting the display brightness, etc. These operation instructions are transmitted to the main control chip 15 through the circuit connection between the button and the warning end motherboard 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 of the bicycle body and trigger the vibration awakening module 14; the vibration awakening module 14 is used to work in conjunction 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 to a comparator circuit. When the vibration signal exceeds the set threshold, 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 entire warning display taillight structure; The warning end Bluetooth module 16 is used to receive signals from the detection end Bluetooth module 10 and transmit the signals to the main control chip 15; the charging management module 17 is responsible for managing the charging and discharging of the battery 19, including monitoring the voltage and power of the battery 19, controlling the charging process, and allocating appropriate power supply voltages to each module in the system. It can realize multiple power supply modes, such as normal working mode, low power sleep mode, etc., and automatically adjust the power supply according to the operating status of the equipment to achieve the purpose of energy saving. When the battery 19 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 issue a corresponding warning.

[0069] When the vibration sensor 13 detects the vibration of the bicycle, for example, the piezoelectric vibration sensor 13 utilizes the piezoelectric effect of the piezoelectric crystal. When mechanical stress is generated by vibration, electric charges are generated on the surface of the crystal to form an electrical signal.

[0070] The capacitive vibration sensor 13 causes the distance or area between the capacitor plates to change through vibration, thereby causing the capacitance value to change and generate an electrical signal. The vibration wake-up module 14 amplifies the weak electrical signal transmitted from the vibration sensor 13 and uses an amplifier circuit to increase the signal amplitude so that the subsequent circuit can accurately identify it.

[0071] Filtering removes 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 a comparator circuit. The comparator compares the signal with a set threshold voltage. When the signal exceeds the threshold, it triggers an interrupt to the main control chip 15, waking it up from a low-power sleep mode.

[0072] When working normally, the main control chip 15 coordinates the work of each module according to the preset program logic. For example, it controls the warning end Bluetooth module 16 to regularly scan and connect to the detection end Bluetooth module 10, performs data analysis and processing after receiving tire pressure data, and determines the display content and flashing mode of the color dot matrix display screen 18 according to the processing results.

[0073] When receiving data, the warning end Bluetooth module 16 performs operations such as unpacking and checking the data in accordance with the Bluetooth communication protocol to ensure the integrity and correctness of the data before transmitting it to the main control chip 15. When monitoring the voltage and power of the battery 19, the charging management module 17 uses technical means such as voltage divider circuits and power metering chips to obtain the status information of the battery 19 in real time.

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

[0075] In the constant voltage charging mode, the battery 19 is first charged with a constant current, and then switched to constant voltage charging when the voltage of the battery 19 reaches the set value, thereby ensuring the safety and efficiency of charging the battery 19.

[0076] When implementing multiple power modes, the different working modes of the power switch tube or power management chip of each module are controlled to switch. For example, in the low-power sleep mode, unnecessary module power is turned off or its operating frequency is reduced to reduce power consumption. When the battery 19 is too low, the power management chip (PMIC) in the charging management module 17 sends a low-battery signal to the main control chip 15. The main control chip 15 controls the color dot matrix display screen 18 to display a low-battery warning icon or text according to this signal to remind 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 convey 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 based on 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 color, brightness and lighting time of each LED point on the display screen according to the instructions.

[0079] like Fig.10 As shown, when the tire pressures of the two tires 3 are sufficient, it means that the riding can be carried out. At this time, the color dot matrix display screen 18 flashes a circle of green lights every 0.5s, and it is performed three times in total;

[0080] When the tire pressure of both tires 3 is insufficient, it means that the riding can be done in a short distance or in a safe state. At this time, the color dot matrix display screen 18 flashes a circle of yellow light every 0.5s, and it is performed three times in total;

[0081] When the tire pressures of the two tires 3 are seriously insufficient, it means that the vehicle cannot be ridden. At this time, the color dot matrix display screen 18 flashes a circle of red lights every 0.5 seconds, and the operation is performed three times in total.

[0082] like Fig.11 As shown, the tire pressure of tire A 3 (the graphic displayed on the left side of the color dot matrix display screen 18 is A at this time, and tire A 3 is the front tire 3 in this application) is sufficient, and the tire pressure of tire B 3 (the graphic displayed on the right side of the color dot matrix display screen 18 is B at this time, and tire B 3 is the rear tire 3 in this application) is insufficient, which means that the state 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 0.5s, and it is executed three times in total;

[0083] If the tire pressure of tire A 3 is insufficient and the tire pressure of tire B 3 is sufficient, it means that the state is that short distance or safe riding is possible. At this time, the color dot matrix display screen 18 will be displayed as A yellow and B green, 0.5s, flashing once every 0.5s, and executed three times in total.

[0084] like Fig.12 As shown, when the tire pressure of tire A 3 is seriously deflated and the tire pressure of tire B 3 is sufficient, it means that riding is not allowed. At this time, the color dot matrix display screen 18 will be displayed as A red and B green, flashing once every 0.5s, and it is executed three times in total;

[0085] If the tire A 3 is seriously deflated and the tire B 3 is under-inflated, it means that riding is not possible. At this time, the color dot matrix display screen 18 will be displayed as A red and B yellow, flashing once every 0.5s, and executed three times in total.

[0086] like Fig.13 As shown, when the tire pressure of tire B 3 is seriously deflated and the tire pressure of tire A 3 is sufficient, it means that riding is not allowed. At this time, the color dot matrix display screen 18 will display A as green and B as red, flashing once every 0.5s, and it is executed three times in total;

[0087] If the B tire 3 is seriously deflated and the A tire 3 is under-inflated, it means that riding is not possible. At this time, the color dot matrix display screen 18 will display A in yellow and B in red, flashing once every 0.5s, and executing three times in total.

[0088] like Fig.14 As shown, the color dot matrix display screen 18 will display various patterns at this time, and the user can choose the corresponding pattern according to his or her own preferences. At this time, it is indicated as a warning to the rear vehicle.

[0089] like Fig.15 As shown, when it is necessary to actively check the tire pressure, only the second button 22 needs to be actively pressed, and the color dot matrix display screen 18 will display the specific tire pressure value as shown in the figure.

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

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

[0092] After the detection end analog-to-digital conversion module 8 converts the analog signal into a digital signal, the detection end microcontroller 9 performs data filtering, calibration and other processing on the digital signal 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 stationary or low-power state, the vibration sensor 13 detects the vibration of the bicycle and generates an electrical signal change. After being processed 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 and enters a normal working state, ready to receive and process tire pressure data.

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

[0097] The charging management module 17 continuously monitors the voltage and power of the battery 19, controls the charging process during charging, allocates appropriate power supply voltage to each module of the system, and sends a low power signal to the main control chip 15 when the power of the battery 19 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 taillight structure through the first button 21 and the second button 22, such as checking the tire pressure of different tires 3, setting warning values, etc.

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