Description

Technical Field

[0001] This invention relates to the field of air pump technology, specifically to an intelligent air pump automatic air replenishment system and its usage method. Background Technology

[0002] With the increasing popularity of new energy intelligent vehicles, users have placed higher demands on the convenience and safety of vehicle use. Whether tire pressure is within the standard range directly affects driving safety, driving range, and tire lifespan. Currently, although most new energy vehicles on the market are equipped with tire pressure monitoring systems, they can only issue an alarm when low tire pressure is detected; subsequent inflation still requires manual operation by the user. In traditional inflation equipment, ordinary air pumps require users to manually query and set the pressure value. However, different vehicle models and tire sizes have different pressure standards, and users are prone to incorrect inflation pressure due to memory errors or untimely queries. Some air pumps claiming to be "intelligent" only support interaction with mobile apps and are not deeply integrated with the vehicle's infotainment system. They cannot directly obtain the vehicle's specific tire pressure standard and winter / summer pressure adaptation coefficient, and lack integrated functions for automatically determining the inflation timing and completing inflation automatically, failing to fundamentally solve the user's operational difficulties.

[0003] Traditional solutions require users to manually check and set tire pressure values, making it difficult to accurately determine the tire pressure standards for different vehicle models and adapt to the differences in tire pressure between winter and summer. This can easily lead to safety hazards due to operational errors. Existing smart air pumps are mostly linked to mobile apps, making it difficult to directly obtain vehicle-specific parameters and lacking the function of automatically verifying tire pressure data and automatically completing the entire inflation process. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent air pump automatic air replenishment system and its usage method, so as to solve the problems of traditional air pump solutions in the prior art that require manual air pressure setting and are difficult to adapt to different vehicle models and winter and summer tire pressures, and intelligent air pumps that rely on mobile phone APPs and are difficult to obtain vehicle-specific parameters.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent air pump automatic inflation system, comprising a vehicle infotainment system, an intelligent air pump, and a tire pressure sensor:

[0006] The vehicle system includes a vehicle parameter database, a Bluetooth communication module, a tire pressure data processing module, a command generation module, a tire pressure abnormality prompt unit, and a winter / summer air pressure automatic conversion unit. The vehicle parameter database stores the standard air pressure range corresponding to the tire model and the winter / summer air pressure correction coefficient.

[0007] The intelligent air pump includes a Bluetooth communication module, an air pressure detection module, an inflation control module, a display module, and a connection memory unit. The Bluetooth communication module is compatible with the Bluetooth communication module of the vehicle system.

[0008] The tire pressure sensors are installed inside each tire, and the tire pressure sensors collect tire pressure data in real time and transmit it to the tire pressure data processing module.

[0009] Furthermore, the air pressure correction coefficients for the vehicle system in winter and summer are as follows: the winter correction coefficient is 5%-10% higher than the standard air pressure value, and the summer correction coefficient is 5%-10% lower than the standard air pressure value.

[0010] Furthermore, the connection memory unit is used to store the Bluetooth connection parameters of the vehicle system, supporting automatic connection upon subsequent power-on after the initial pairing.

[0011] Furthermore, the intelligent air pump is equipped with an air nozzle at its inflation end. The air nozzle is made of brass and is compatible with the valve stems of TR413 / TR415 tires.

[0012] A method for automatically replenishing air in an intelligent air pump includes the following steps:

[0013] S1. When the tire pressure sensor detects that the tire pressure is lower than the standard lower limit for the corresponding season, the vehicle system will issue a low air pressure warning. After the user turns on the smart air pump, it will automatically connect to the vehicle system via Bluetooth.

[0014] S2. The vehicle's infotainment system and intelligent air pump simultaneously display the location of the low-inflation tire. The user installs the valve assembly and ensures a seal.

[0015] S3, the intelligent air pump and tire pressure sensor collect tire pressure data and transmit it to the vehicle system. After the data is verified, the vehicle system issues a target air pressure command.

[0016] S4. The intelligent air pump automatically inflates after receiving the command, and automatically stops and prompts the user after reaching the target air pressure. It then automatically enters standby mode.

[0017] Furthermore, the vehicle's infotainment system in the S1 identifies the current season through a built-in ambient temperature sensor and clock module, and automatically switches to the corresponding air pressure standard.

[0018] Furthermore, the preset error range for data verification in S3 is ±0.02 bar. When the data difference exceeds this range, the vehicle system prompts the user to check the valve installation.

[0019] Furthermore, in the S1, the smart air pump needs to be manually paired with the vehicle system via Bluetooth upon first use. After successful pairing, the connection memory unit stores the connection parameters, and the system will automatically connect within 10 seconds of subsequent power-on.

[0020] Compared with existing technologies, the intelligent air pump automatic inflation system provided by this invention works in conjunction with the vehicle's infotainment system, intelligent air pump, and tire pressure sensors. Relying on the vehicle parameter database to store tire pressure standards and an automatic winter / summer conversion unit, it eliminates the need for users to manually query and set the air pressure. It can accurately adapt to the tire pressure requirements of different vehicle models and seasons, effectively avoiding the risk of operational errors. The intelligent air pump directly obtains vehicle-specific parameters from the vehicle's infotainment system, and with tire pressure verification, automatic inflation throughout the entire process, and shutdown prompts, it greatly simplifies the operation process, shortens inflation preparation and execution time, and comprehensively ensures driving safety.

[0023] Figure 2 This is a schematic diagram of the vehicle infotainment system modules. Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 2 As shown:

[0026] Example 1:

[0027] This invention provides an intelligent air pump automatic inflation system, comprising a vehicle infotainment system, an intelligent air pump, and a tire pressure sensor, which work together to achieve automatic inflation.

[0028] The vehicle system includes a vehicle parameter database, a Bluetooth communication module, a tire pressure data processing module, a command generation module, a tire pressure abnormality warning unit, and a winter / summer air pressure automatic conversion unit. The vehicle parameter database stores the standard air pressure range corresponding to the tire model and the winter / summer air pressure correction coefficient.

[0029] The intelligent air pump includes a Bluetooth communication module, an air pressure detection module, an inflation control module, a display module, and a connection memory unit. The Bluetooth communication module is compatible with the Bluetooth communication module of the vehicle system. The intelligent air pump has an air valve installed at the inflation end. The air valve is made of brass and is compatible with TR413 / TR415 tire valves and has a sealing function.

[0030] Tire pressure sensors are installed inside each tire, and the tire pressure sensors collect tire pressure data in real time and transmit it to the tire pressure data processing module.

[0031] The vehicle infotainment system's seasonal air pressure correction coefficients are as follows: the winter correction coefficient is 5%-10% higher than the standard air pressure value, and the summer correction coefficient is 5%-10% lower than the standard air pressure value; the connection memory unit is used to store the vehicle infotainment system's Bluetooth connection parameters, and supports automatic connection upon subsequent power-ups after the initial pairing.

[0032] The usage method includes the following steps:

[0033] S1. When the tire pressure sensor detects that the tire pressure is lower than the standard lower limit for the corresponding season, the vehicle system will issue a low air pressure warning. After the user turns on the smart air pump, it will automatically connect to the vehicle system via Bluetooth.

[0034] The vehicle system identifies the current season through a built-in ambient temperature sensor and clock module, and automatically switches to the corresponding air pressure standard. When using it for the first time, you need to manually pair the smart air pump with the vehicle system via Bluetooth. After successful pairing, the connection memory unit stores the connection parameters, and it will automatically connect within 10 seconds of powering on.

[0035] S2. The vehicle's infotainment system and intelligent air pump simultaneously display the location of the low-inflation tire. The user installs the valve assembly and ensures a seal.

[0036] S3, the intelligent air pump and tire pressure sensor collect tire pressure data and transmit it to the vehicle system. After the data is verified, the vehicle system issues a target air pressure command. The preset error range for data verification is ±0.02 bar. If the data difference exceeds this range, the vehicle system prompts the user to check the valve installation.

[0037] S4. The intelligent air pump automatically inflates after receiving the command, and automatically stops and prompts the user after reaching the target air pressure. It then automatically enters standby mode.

[0038] Example 1: Low Temperature Scenario in Winter

[0039] Component parameters and adaptation requirements: The vehicle system adopts Bluetooth version 5.0 and supports BLE low power communication. It has a built-in ambient temperature sensor with a measurement range of -40℃ to 85℃ and an accuracy of ±0.5℃ to achieve seasonal recognition. The vehicle parameter database has a pre-stored standard air pressure range of 2.2-2.5 bar for 225 / 55R18 tires. The winter air pressure correction factor is set to 1.08. The preset error range for dual tire pressure verification is ±0.02 bar. The response time of the tire pressure abnormality warning unit is ≤1 second.

[0040] The smart air pump's Bluetooth communication module is compatible with the vehicle's infotainment system's Bluetooth module, supporting automatic connection within 10 seconds of power-on after initial pairing. The air pressure detection module has a detection accuracy of ±0.01 bar. The inflation control module controls the inflation motor's inflation pressure range of 0-8 bar and inflation flow rate of 35 L / min. The display module is a 2.4-inch LCD screen that supports real-time tire pressure data display, inflation progress bar, and status prompts that refresh every 0.5 seconds. The connection memory unit can store at least one set of vehicle Bluetooth connection parameters. The built-in backup power supply supports continuous inflation time of ≥30 minutes and standby power consumption of ≤5mA. The valve assembly is made of brass and is compatible with TR413 tire valves.

[0041] The tire pressure sensor is a wireless radio frequency (RF) type, with an operating frequency of 433MHz, static power consumption ≤3μA, wake-up threshold of 0.01bar, data transmission interval of 10 seconds in driving mode and 60 seconds in stationary mode, transmission distance ≥10 meters, and battery life ≥5 years.

[0042] Tire pressure sensors are installed in all four tires. After starting the vehicle, enter the "Tire Pressure Monitoring Settings" interface of the vehicle's infotainment system and select the "Sensor Matching" function. The system identifies the sensor IDs one by one via RF signals and completes the binding. After binding, the central control screen displays that the signal strength of each sensor is ≥-85dBm, and the data transmission is stable. In the "Auxiliary Equipment" module of the infotainment system, select "Intelligent Air Pump Adaptation," enter the current vehicle's 225 / 55R18 tire information, and the system automatically matches the pre-stored standard air pressure range. The user confirms the winter correction factor of 1.08 based on the low winter temperatures of their region.

[0043] The system automatically calculates the target tire pressure for winter as 2.3 bar × 1.08 = 2.48 bar, and sets a tire pressure abnormality warning threshold that triggers a warning when the pressure is 10% lower than the target pressure (i.e., 2.23 bar). The intelligent air pump is charged for approximately 2 hours using 12V until the green light is constantly on; then, the power button is pressed and held for 3 seconds to turn it on. In the vehicle's Bluetooth settings, the system searches for the air pump's Bluetooth name "AirPump," clicks to pair, and enters the preset pairing code "1234." After successful pairing, the vehicle's system displays "Connection Successful," and the intelligent air pump connects to the memory unit to store the vehicle's Bluetooth connection parameters. The left front tire pressure is manually reduced to 2.0 bar to verify the vehicle's system's timely low-pressure warning. The intelligent air pump is then connected to the left front tire valve, and the error between the two sets of tire pressure data is checked to be ≤ ±0.02 bar. A inflation command is issued to verify the accuracy of the intelligent air pump's start-up, progress bar display, and automatic shutdown after the tire pressure reaches the target, ensuring that all system components function properly.

[0044] When the ambient temperature is -5℃, the left front tire pressure sensor detects a tire pressure of 2.2 bar during vehicle operation. This value is lower than the warning threshold of 2.23 bar for the winter target tire pressure of 2.48 bar. The sensor immediately transmits the data to the vehicle system. The vehicle system's tire pressure abnormality warning unit displays the words "Left front tire low on air" in red and a location diagram on the central control screen, while simultaneously announcing in voice "Left front tire pressure is low, please turn on the intelligent air pump."

[0045] After the user takes out the smart air pump and turns it on, the user connects to the memory unit to retrieve the stored Bluetooth parameters and automatically connects to the vehicle system within 8 seconds. The smart air pump display module simultaneously displays "Left front tire is low on air, waiting for valve installation". The user follows the instructions to unscrew the dust cap of the left front tire valve, tightens the smart air pump valve to the valve and confirms a sealed installation. The smart air pump is then tested and found to have no air leaks.

[0046] The tire pressure detection module collects the current tire pressure of 2.21 bar and transmits it to the vehicle system. The vehicle system simultaneously receives the 2.2 bar data transmitted by the tire pressure sensor. The difference between the two sets of data is 0.01 bar (≤±0.02 bar), which is verified. The vehicle system's winter and summer tire pressure automatic conversion unit identifies that it is currently winter through the ambient temperature sensor. The instruction generation module issues a target tire pressure of 2.48 bar and an air replenishment instruction.

[0047] The intelligent air pump inflation control module starts the inflation motor, and the display module progress bar dynamically updates according to the initial progress of (2.48-2.21) / (2.48-2.2)×100%≈96%, simultaneously displaying the current tire pressure and target tire pressure. The vehicle system simultaneously displays the remaining inflation time of approximately 1.2 minutes.

[0048] When the tire pressure reaches 2.48 bar, the intelligent air pump automatically stops and displays "Inflation complete" and emits a beeping sound. The vehicle's infotainment system simultaneously announces "Left front tire inflation complete, current pressure 2.48 bar". After the user removes the valve stem, the intelligent air pump enters standby mode within 10 seconds and the Bluetooth connection automatically disconnects after 30 seconds.

[0049] This tire inflation process requires no manual setting of tire pressure parameters by the user. It only involves three steps: "power on → install valve → remove valve". After inflation, the tire pressure is accurately 2.48 bar with an error of ≤ ±0.01 bar, which is suitable for the tire pressure requirements in low-temperature winter conditions. It effectively avoids the impact of low tire pressure on driving stability, and is convenient, safe and reliable to operate.

[0050] Example 2: High Temperature Scenario in Summer

[0051] Component parameters and compatibility requirements: The vehicle system uses Bluetooth version 5.0 and supports BLE low-power communication. It has a built-in ambient temperature sensor with a measurement range of -40℃ to 85℃ and an accuracy of ±0.5℃ to achieve seasonal recognition. The vehicle parameter database has a pre-stored standard tire pressure range of 2.2-2.5 bar for 225 / 55R18 tires. The summer tire pressure correction factor is set to 0.92. The preset error range for dual tire pressure verification is ±0.02 bar. The response time of the tire pressure abnormality warning unit is ≤1 second.

[0052] The smart air pump's Bluetooth communication module is compatible with the vehicle's infotainment system's Bluetooth module, supporting automatic connection within 10 seconds of power-on after initial pairing. The air pressure detection module has a detection accuracy of ±0.01 bar. The inflation control module controls the inflation motor's inflation pressure range of 0-8 bar and inflation flow rate of 35 L / min. The display module is a 2.4-inch LCD screen, supporting real-time tire pressure data display, inflation progress bar, and status prompts that are refreshed every 0.5 seconds. The connection memory unit can store at least one set of vehicle infotainment system Bluetooth connection parameters. The built-in backup power supply supports continuous inflation time of ≥30 minutes and standby power consumption of ≤5mA. The valve assembly is made of brass and is compatible with TR415 tire valves.

[0053] The tire pressure sensor is a wireless radio frequency (RF) type, with an operating frequency of 433MHz, static power consumption ≤3μA, wake-up threshold of 0.01bar, data transmission interval of 10 seconds in driving mode and 60 seconds in stationary mode, transmission distance ≥10 meters, and battery life ≥5 years.

[0054] Tire pressure sensors are installed in all four tires. After starting the vehicle, enter the "Tire Pressure Monitoring Settings" interface of the vehicle's infotainment system and select the "Sensor Matching" function. The system identifies the sensor IDs one by one via RF signals and completes the binding. After binding, the central control screen displays that the signal strength of each sensor is ≥-85dBm, and the data transmission is normal. In the "Auxiliary Equipment" module of the infotainment system, select "Intelligent Air Pump Adaptation," enter the current vehicle's 225 / 55R18 tire information, and the system automatically matches the pre-stored standard tire pressure range. The user confirms the summer correction factor of 0.92 based on the high summer temperatures in their region.

[0055] The system automatically calculates the target air pressure value for summer as 2.3 bar × 0.92 = 2.12 bar, and sets a tire pressure abnormality warning threshold that triggers a prompt when the air pressure is 10% lower than the target pressure (i.e., 1.91 bar). The intelligent air pump is charged for approximately 2 hours using 12V until the green light is constantly on; then, the power button is pressed and held for 3 seconds to turn it on. In the vehicle's Bluetooth settings, the system searches for the intelligent air pump's Bluetooth name "AirPump," clicks to pair, and enters the preset pairing code "1234." After successful pairing, the vehicle's system displays "Connection Successful," and the intelligent air pump connects to the memory unit to store the vehicle's Bluetooth connection parameters. The right rear tire pressure is manually reduced to 1.8 bar to verify the vehicle's system's timely low-pressure warning. The intelligent air pump is then connected to the right rear tire valve, and the error between the two sets of tire pressure data is checked to be ≤ ±0.02 bar. A inflation command is issued to verify the accuracy of the intelligent air pump's start-up, progress bar display, and automatic shutdown after the tire pressure reaches the target, ensuring that all system components function properly.

[0056] When the ambient temperature is 35℃, the right rear tire pressure sensor detects a tire pressure of 1.9 bar while the vehicle is stationary. This value is lower than the warning threshold of 1.91 bar for the summer target tire pressure of 2.12 bar. The sensor immediately transmits the data to the vehicle system. The vehicle system's tire pressure abnormality warning unit displays "Right rear tire low on air" and a location indicator on the central control screen, and at the same time announces "Right rear tire pressure is low, please turn on the intelligent air pump" in voice.

[0057] After the user removes and powers on the smart air pump, the memory unit retrieves stored Bluetooth parameters, and the system automatically connects to the vehicle's infotainment system within 6 seconds. The smart air pump's display module simultaneously shows "Right rear tire low on air, awaiting valve installation." Following the instructions, the user unscrews the dust cap from the right rear tire valve, tightens the smart air pump valve to the valve, and confirms a leak-free seal. The smart air pump detects no leaks and displays a warning. The tire pressure detection module collects the current tire pressure of 1.91 bar and transmits it to the vehicle's infotainment system. The system simultaneously receives the 1.9 bar data from the tire pressure sensor. The difference between the two sets of data is 0.01 bar (≤±0.02 bar), verifying successful connection. The vehicle's automatic winter / summer tire pressure conversion unit uses the ambient temperature sensor to identify the current temperature. In summer, the instruction generation module issues a target tire pressure of 2.12 bar and an inflation command; the intelligent air pump inflation control module starts the inflation motor, and the display module's progress bar dynamically updates according to the initial progress of (2.12-1.91) / (2.12-1.9)×100%≈95%, simultaneously displaying the current tire pressure and the target tire pressure. The vehicle system simultaneously displays approximately 1.5 minutes of remaining inflation time; when the tire pressure reaches 2.12 bar, the intelligent air pump automatically stops and displays "Inflation complete" and emits a beeping prompt. The vehicle system simultaneously announces in voice, "Right rear tire inflation complete, current pressure 2.12 bar"; after the user removes the valve stem, the intelligent air pump enters standby mode within 10 seconds, and the Bluetooth connection automatically disconnects after 30 seconds.

[0058] This tire inflation process requires no manual setting of tire pressure parameters by the user, and the operation is simple and convenient. After inflation, the tire pressure reaches an accurate 2.12 bar with an error of ≤ ±0.01 bar, which is suitable for the tire anti-inflation needs in high-temperature summer environments and effectively avoids the risk of tire blowout caused by excessive tire pressure. The system has good stability and practicality.

[0059] Example 3: High-temperature summer scenario - Re-inflating after pairing

[0060] When the ambient temperature is 36℃, after driving for 15 minutes and parking on the side of the road, the right front tire pressure sensor detected a tire pressure of 1.9 bar, which is lower than the warning threshold of 1.91 bar for the summer target tire pressure of 2.12 bar. The sensor immediately transmits the data to the vehicle's infotainment system. The vehicle's infotainment system's tire pressure abnormality warning unit displays "Right front tire low on air" and a location indicator on the central control screen, while simultaneously announcing in voice, "Right front tire pressure is low, please turn on the smart air pump."

[0061] The user removes the smart air pump and presses and holds the power button for 3 seconds to turn it on. The system quickly retrieves stored Bluetooth parameters from the vehicle's memory unit and automatically connects to the vehicle's system within 5 seconds. The smart air pump display module simultaneously shows "Right front tire low on air, waiting for valve installation." Following the instructions, the user unscrews the dust cap from the right front tire valve, tightens the smart air pump valve to the valve, and confirms a tight seal. The smart air pump display module briefly indicates "Valve installation normal." The tire pressure detection module collects the current tire pressure of 1.91 bar in real time and transmits it to the vehicle's system via Bluetooth. The vehicle's system simultaneously receives the 1.9 bar data from the right front tire pressure sensor. The difference between the two sets of data is 0.01 bar (≤±0.02 bar), indicating successful verification.

[0062] The vehicle's infotainment system's automatic winter / summer tire pressure conversion unit identifies summer as the current season using an ambient temperature sensor. The command generation module quickly issues a target tire pressure of 2.12 bar and a "start inflating" command. Upon receiving the command, the intelligent air pump control module immediately starts the inflation motor. The progress bar on the display module dynamically updates according to an initial progress of (2.12-1.91) / (2.12-1.9)×100%≈95%, simultaneously displaying the current tire pressure (refreshed every 0.5 seconds) and the target tire pressure of 2.12 bar. The vehicle's infotainment system's central control screen simultaneously displays the inflating progress and approximately 1.5 minutes of remaining inflating time. When the tire pressure detection module detects that the tire pressure has reached 2.12 bar, it immediately sends a stop signal to the inflation control module. The inflation motor stops working, the intelligent air pump display module displays "Inflation complete" in green and emits 3 beeps. The vehicle system simultaneously announces "Right front tire inflation complete, current pressure 2.12 bar" via voice. The user unscrews the intelligent air pump nozzle counterclockwise and screws back the valve cap. The intelligent air pump automatically shuts off the display module within 10 seconds of removing the nozzle and enters a low-power standby state. The Bluetooth connection between the vehicle system and the intelligent air pump is maintained for 30 seconds before automatically disconnecting.

[0063] This re-inflation process did not involve any Bluetooth pairing or parameter settings. It only required three simple steps: "powering on, installing the valve stem, and removing the valve stem." After inflation, the tire pressure accurately reached the target value of 2.12 bar with an error of ≤ ±0.01 bar. This meets the tire anti-inflation requirements in high-temperature summer environments and effectively avoids the risk of tire blowout caused by excessive tire pressure. At the same time, relying on the stored connection parameters and preset air pressure standards, the connection and inflation preparation time was significantly shortened, further highlighting the system's stability and ease of use.

[0064] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
