Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of air pressure detection, especially to the straight -line type straight -cylinder flash lamp tire pressure monitoring device of non -motor vehicle. BACKGROUND

[0002] In today's short -distance travel field, bicycles and electric vehicles have become the popular choice of the public for daily commuting, leisure exercise because of their convenient and environmental characteristics. As the key component of their contact with the ground, whether the tire pressure is in the appropriate state has a crucial influence on the safety, comfort and energy utilization efficiency (for electric vehicles).

[0003] The traditional tire pressure monitoring technology has shown different forms and problems when applied in the field of automobiles. Similarly, when considering adapting it to bicycles and electric vehicles, the limitations of the original technology are more prominent. On the one hand, the indirect tire pressure monitoring system relies on the wheel speed sensor to indirectly calculate the tire pressure. In the relatively simple electronic control system of bicycles and electric vehicles, it is difficult to achieve accurate wheel speed comparison and analysis. Moreover, since the driving speed of these two types of vehicles is usually lower than that of cars, the sensitivity of wheel speed change to tire pressure is lower, and the detection accuracy is difficult to meet the actual demand. For example, when a bicycle tire has a slight slow leak, the air pressure slowly decreases, and the indirect system often fails to detect it in time. It may not be until the rider feels that the ride is difficult, or even the tire has been severely deflated to affect the control, that the warning is given, which undoubtedly poses a safety hazard to the riding process.

[0004] On the other hand, in terms of gas flow stability, due to the different vibration frequency and amplitude during the riding process of bicycles and electric vehicles, the side air inlet method is more likely to cause turbulence in the detection area, interfering with the work of the detection element. For example, when driving on a bumpy road, the violent shaking of the vehicle makes the already unstable side airflow even more complex, causing the detection result to fluctuate frequently and unable to provide accurate and continuous tire pressure information for the rider. Furthermore, considering that bicycles and electric vehicles are often parked outdoors, they are more vulnerable to rain and dust. The multiple sealed connection parts of the side air inlet design are easily damaged. Once the seal is not tight, rainwater may directly damage the detection element, shortening the service life of the device. Frequent maintenance and replacement not only consumes money but also energy.

[0005] Therefore, we propose a straight-line type straight-cylinder flash lamp tire pressure monitoring device for non-motor vehicles. Utility model content

[0048] Embodiments

[0049] As shown in Figures 1-6 The present application provides a technical scheme: a straight row type straight cylinder flash lamp tire pressure monitoring device for a non-motor vehicle, comprising: an air inlet bottom shell assembly directly connected to a tire valve, the air inlet bottom shell assembly being used for receiving gas in the tire.

[0050] The core of this design is to establish a direct connection channel between the device and the internal gas environment of the tire. The air inlet bottom shell assembly closely fits the tire valve, ensuring that the gas in the tire can flow smoothly and unobstructed into the device. The principle is to use the close connection with the valve to minimize pressure loss during gas transmission, ensuring that the gas sample used for subsequent detection accurately reflects the tire pressure. For example, during cycling, the gas in the tire may experience instantaneous high or low pressure fluctuations due to road bumps. If the air inlet link is blocked or unstable, the pressure entering the device will be biased, resulting in inaccurate detection results. This direct connection design is like a "highway" for gas, allowing it to enter smoothly.

[0051] When the tire is inflated and begins to be used, the gas naturally flows to the air inlet bottom shell assembly connected directly to the valve due to the pressure inside the tire, preparing for the subsequent detection process.

[0052] The connection of the air inlet bottom shell assembly is provided with a transparent shell assembly, and the connection of the air inlet bottom shell assembly is provided with a transparent shell assembly. The inside of the transparent shell assembly is provided with a detection assembly, and the bottom of the detection assembly and the end of the air inlet bottom shell assembly are provided with a gas pressure sensor 10 for detecting gas pressure.

[0053] The transparent shell assembly plays a dual role of protection and visualization. On the one hand, it provides a relatively closed and stable environment for the internal detection assembly, resisting possible physical impact from the outside world. On the other hand, the transparent material allows users to directly observe the working status of some key components inside, such as the flashing red and green lights 13. The gas pressure sensor 10 of the detection assembly is a key component that works on the principle of pressure to electrical signal conversion. When the gas pressure acts on the sensor's sensing element, it causes physical deformation of the element, which in turn converts into corresponding electrical signal changes. These electrical signals are transmitted to subsequent circuit modules for analysis and processing.

[0054] After the gas flows from the air inlet bottom shell assembly into the transparent shell assembly, it is immediately captured by the gas pressure sensor 10 at the bottom end. The gas pressure sensor 10 converts the tire gas pressure into an electrical signal in real time and transmits it to other circuit modules in the detection assembly. Under normal circumstances, the pressure sensor continuously detects the gas in the tire to ensure that the tire pressure status can be monitored in real time.

[0055] The top of the transparent shell assembly is provided with a top exhaust assembly connected thereto. The top exhaust assembly is located at the top of the device and is used to exhaust the detected gas. The air inlet bottom shell assembly, transparent shell assembly, detection assembly, and top exhaust assembly form a straight-line gas flow channel to achieve direct gas entry and exhaust, ensuring the accuracy and stability of the detection.

[0056] The straight gas flow channel is designed based on the principle of fluid mechanics. In a continuous, un-bent channel, the gas flow is more stable and less likely to form turbulence. Compared with a curved or complex structure channel, the straight type can reduce the collision between gas molecules and the friction with the pipe wall, avoiding additional pressure loss and air flow disturbance. This not only guarantees the accuracy of the data collected by the air pressure sensor 10, but also makes the entire detection process efficient and stable. Just like running water in a straight pipe, the water flow is uniform and the pressure is stable; in a curved pipe, the water flow is prone to eddy, uneven flow, etc., affecting the accuracy of water pressure measurement.

[0057] When manual deflation is performed, the gas naturally rises along the straight channel and reaches the top exhaust assembly, i.e. the valve core 302 at the top of the upper mounting shell 301. The valve core 302 is similar to a one-way valve. When the internal pressure of the device is higher than the external environment, the gas pushes open the valve core 302 to exhaust and return to the external atmospheric environment, so that the tire internal pressure gradually recovers to a relatively safe level; in the non-exhaust state, the valve core 302 is tightly closed to maintain the stability of the internal environment of the device, the third connecting thread 303 on the inner wall of the upper mounting shell 301 is stably connected with the transparent shell assembly, and the sealing performance of the entire gas channel is guaranteed to prevent foreign matter from flowing into the device.

[0058] The air inlet bottom shell assembly includes a lower mounting shell 201, the bottom of the lower mounting shell 201 is provided with a gas nozzle connector 202, the inside of the lower mounting shell 201 is provided with a gas passage 203, and the outer side of the lower mounting shell 201 is provided with a second connecting thread 204.

[0059] The lower mounting shell 201 is the main structure of the air inlet bottom shell assembly. The gas nozzle connector 202 is an "interface" directly connected with the tire valve, and its fine design ensures close fit with the valve to prevent air leakage. The gas passage 203 provides an internal passage for gas to enter, allowing the gas entering from the valve to flow smoothly to the subsequent components. The second connecting thread 204 on the outer side is used to connect with other components, such as the transparent shell assembly, through a threaded connection, which can not only ensure the firmness of the connection, but also facilitate disassembly and maintenance, following the principles of reliability and convenience of mechanical connection.

[0060] The gas nozzle connector 202 is screwed and fixed with the tire valve during initial installation, and the gas in the tire enters the gas passage 203 inside the lower mounting shell 201 through the gas nozzle connector 202 to provide a gas source for subsequent detection; when maintenance or replacement of components is required, the lower mounting shell 201 can be easily unscrewed using the second connecting thread 204.

[0061] The transparent shell assembly includes an outer transparent shell 101, and the inner wall of the outer transparent shell 101 is provided with a first connecting thread 102 at both ends. The inner wall of the outer transparent shell 101 is further provided with an inner protective transparent shell 7.

[0062] The outer transparent shell 101 plays a supporting and connecting role in structure, and the first connecting threads 102 at both ends are used to be closely connected with the air inlet bottom shell assembly and the top exhaust assembly to build a complete gas passage. The inner protective transparent shell 7 is a secondary protection for the internal detection assembly, which prevents the fine dust, water vapor and other impurities from breaking through the outer transparent shell 101 to cause damage to the precise detection elements, and at the same time does not affect the visual observation, which is a multi-layer protection and practical design.

[0063] When working, the outer transparent shell 101 is connected with the lower mounting shell 201 and the upper mounting shell 301 through the first connecting threads 102 respectively to ensure the sealing of the gas passage; the inner protective transparent shell 7 always guards the internal detection components such as the PCB circuit board 5, which can maintain the normal working environment of the detection components as much as possible even in harsh environments.

[0064] The detection assembly includes the PCB circuit board 5, and the MCU 11, the power module 12 and the flashing red and green light 13 are respectively installed on the PCB circuit board 5, and the MCU 11, the power module 12 and the flashing red and green light 13 are electrically connected with the PCB circuit board 5.

[0065] The PCB circuit board 5 is a bearing platform which integrates multiple key functional modules. The MCU 11 (micro control unit) is the "intelligent core" of the entire detection system, which receives the electrical signal transmitted by the air pressure sensor 10, analyzes and processes the data according to the preset program algorithm, and judges whether the tire pressure is within the normal range. The power module 12 provides stable power support for the entire detection assembly to ensure the normal operation of each component. The flashing red and green light 13 is an intuitive warning device, which flashes at a specific frequency when the MCU 11 judges that the tire pressure is abnormal, and sends an alarm to the rider.

[0066] Hereinafter, the operation principle of the detection and flashing light will be described in detail: after the air pressure sensor 10 converts the gas pressure in the tire into an electrical signal and transmits it to the MCU 11, the high-precision A / D (analog / digital) converter built in the MCU 11 first digitizes the electrical signal and converts it into a digital signal for subsequent operation and analysis. The MCU 11 pre-stores standard tire pressure range values for different types of non-motor vehicles (such as bicycles, electric vehicles, etc.), which are optimized and set after a large number of experimental tests and actual riding data collection. The MCU 11 compares the received digitized air pressure value with the corresponding standard tire pressure range in real time. Once the air pressure value is detected to be out of the standard range, whether it is higher than the upper limit value (which may indicate that the tire is overinflated and has the risk of tire burst) or lower than the lower limit value (which means that the tire may have a slow leakage phenomenon), the MCU 11 will immediately start the warning program.

[0067] When the warning program is started, the MCU 11 sends control instructions to the driving circuit connected to the flashing red and green light 13 according to the preset logic. The driving circuit is generally a power amplifier circuit composed of transistors, resistors and other electronic elements, which can amplify the weak control signal output by the MCU 11 to provide sufficient current to drive the flashing red and green light 13 to work. After receiving the instructions of the MCU 11, the driving circuit provides intermittent power supply for the flashing red and green light 13 according to the established frequency and mode, so that the red and green light flashes at a specific frequency, such as fast flashing red light indicating serious low pressure danger, slow flashing yellow light indicating slight low pressure or high pressure warning, etc., thereby directly conveying the tire pressure abnormal information to the rider.

[0068] In daily work, the MCU 11 continuously receives data of the air pressure sensor 10, and the power module 12 provides uninterrupted power supply, ensuring that the entire detection system is in standby state at all times. Once the tire pressure exceeds the normal range, the MCU 11 drives the flashing red and green light 13 to issue a warning signal, and the rider can see it at a glance through the transparent shell.

[0069] The top exhaust assembly includes an upper mounting shell 301, and the top of the upper mounting shell 301 is provided with a valve core 302, and the inner wall of the upper mounting shell 301 is provided with a third connecting thread 303.

[0070] The upper mounting shell 301 cooperates with the transparent shell assembly to complete the exhaust function. The valve core 302 at the top is similar to a one-way valve. When the internal pressure of the device is higher than the outside, the gas can push open the valve core 302 to exhaust when the exhaust condition is met. In the non-exhaust state, the valve core 302 is tightly closed to prevent foreign matter from flowing into the device. The third connecting thread 303 on the inner wall is used to stably connect with the transparent shell assembly to ensure the sealing of the entire gas channel, which is also a mechanical connection to ensure the sealing and functionality.

[0071] In work, the valve core 302 is normally closed to maintain the stability of the internal environment of the device. When the tire leaks and requires exhaust, the detected gas is pushed out by the pressure in the device to open the valve core 302, and the third connecting thread 303 ensures that the upper mounting shell 301 and the transparent shell are tightly matched without gas leakage.

[0072] The upper mounting shell 301 and the outer transparent shell 101 are connected by the third connecting thread 303 and the first connecting thread 102, and the connection is provided with a second sealing gasket 8.

[0073] The threaded connection provides basic connection strength, ensuring that the upper mounting shell 301 and the outer transparent shell 101 will not be loose and separated under various riding vibration environments. While the second sealing gasket 8 serves as an auxiliary sealing means, further filling the small gaps that may exist at the threaded connection to prevent gas leakage or impurities from entering, providing double protection to improve the overall sealing and reliability of the device, following the mechanical sealing redundancy design principle.

[0074] During daily riding and use, the threaded connection always keeps the upper mounting shell 301 and the outer transparent shell 101 tightly fixed, and the second sealing gasket 8 continuously plays a sealing role, providing protection for stable operation of the device.

[0075] The lower mounting shell 201 is connected to the outer transparent shell 101 through the threaded connection between the air hole 203 and the first connection thread 102, and the connection is provided with a third sealing gasket 9.

[0076] This situation is similar to the connection between the upper mounting shell 301 and the outer transparent shell 101, and the threaded connection ensures structural stability, and the air hole 203 allows gas to pass smoothly. The third sealing gasket 9 focuses on sealing the connection at the gas inlet link to prevent high-pressure gas in the tire from leaking at this point, affecting detection accuracy, because even a small amount of gas leakage can cause the pressure sensor 10 to collect a lower pressure value, giving an incorrect tire pressure normal signal.

[0077] In operation, the lower mounting shell 201 is tightly connected to the outer transparent shell 101 through the threaded connection, and the third sealing gasket 9 blocks gas leakage, ensuring that the gas flows from the tire to the subsequent detection process.

[0078] The inner protective transparent shell 7 also has a plurality of batteries 6, and the plurality of batteries 6 are electrically connected to the PCB circuit board 5.

[0079] The battery 6 is electrically connected to the PCB circuit board 5 to provide power for the detection assembly and maintain the continuous operation of the tire pressure monitoring function.

[0080] The bottom of the inner protective transparent shell 7 is also provided with a sealing plate 14, and the sealing plate 14 and the inner protective transparent shell 7 are also provided with a first sealing gasket 4.

[0081] The sealing plate 14 provides closed protection for the bottom of the inner protective transparent shell 7 to prevent dust, water vapor, etc. from entering from the bottom. The first sealing gasket 4 further enhances the sealing effect between the sealing plate 14 and the inner protective transparent shell 7, and together with other sealing gaskets, it forms a comprehensive protection system to protect the internal detection assembly. Even in rainy and waterlogged road conditions or long-term outdoor parking, the damage of external adverse factors to the device can be minimized.

[0082] During the use of the device, the sealing plate 14 and the first sealing gasket 4 are always on duty to block external impurities and ensure the cleanliness and stability of the internal environment of the transparent housing 7.

[0083] As shown in the figure, it is a schematic diagram of the mouth connection. Figure 6

[0084] Gas inlet process:

[0085] When initially installed, the gas nozzle joint 202 at the bottom of the lower installation shell 201 of the air inlet bottom shell assembly is tightly screwed and fixed with the tire valve, ensuring that there is no gas leakage between the two.

[0086] When the tire is inflated and put into use, due to the certain pressure inside the tire, the gas flows smoothly into the air hole 203 inside the lower installation shell 201 through the "inlet" of the gas nozzle joint 202, and then flows into the entire device, providing a gas source for the subsequent detection link. This process benefits from the precise fitting design of the gas nozzle joint 202 and the valve, as well as the reasonable layout of the air hole 203, which maximizes the stability and smoothness of gas entry, like opening a precise and stable "raw material supply gate" for the subsequent detection process.

[0087] Detection process:

[0088] After the gas flows from the air inlet bottom shell assembly into the transparent housing assembly connected thereto, it is immediately captured by the air pressure sensor 10 located inside the transparent housing assembly and at the end of the air inlet bottom shell assembly.

[0089] The air pressure sensor 10 works according to the pressure and electrical signal conversion principle. When the gas pressure acts on its sensing element, it causes physical deformation of the element, which in turn accurately converts the tire gas pressure into an electrical signal in real time.

[0090] The converted electrical signal is quickly transmitted to the PCB circuit board 5 in the detection assembly, and the PCB circuit board 5, as the core bearing platform of the entire detection system, plays a key role in data processing. The MCU 11 (micro control unit) installed on the PCB circuit board 5 has a built-in high-precision A / D (analog / digital) converter that first digitizes the received electrical signal for subsequent complex operation and analysis. At the same time, the MCU 11 has pre-stored standard tire pressure range values optimized for different non-motorized vehicles (such as bicycles, electric vehicles, etc.), which are derived from a large number of experimental tests and actual riding data collection. The MCU 11 continuously compares the received digitized air pressure value with the corresponding standard tire pressure range in real time, like a strict "data judge", constantly monitoring whether the tire pressure is normal.

[0091] Warning process (when the tire pressure is abnormal):

[0092] ​Once the MCU 11 detects that the air pressure value is out of the standard range, whether it is higher than the upper limit value (meaning that the tire is over-inflated, with the risk of tire burst), or lower than the lower limit value (indicating that the tire may have a slow leak), the MCU 11 will immediately start the warning program according to the preset logic.

[0093] When the warning program is started, the MCU 11 sends a control command to the drive circuit connected to the flashing red-green light 13. The drive circuit is usually composed of transistors, resistors and other electronic components to form a power amplifier circuit, which can effectively amplify the weak control signal output by the MCU 11, thereby providing sufficient current to drive the flashing red-green light 13 to work.

[0094] After receiving the command of the MCU 11, the drive circuit provides intermittent power supply for the flashing red-green light 13 according to the predetermined frequency and mode, so that the red-green light flashes at a specific frequency. For example, a fast flashing red light indicates a serious low pressure danger, warning the rider to stop and check immediately; a slow flashing yellow light indicates a slight low pressure or high pressure warning, prompting the rider to handle the tire pressure problem at the right time. Through this intuitive and eye-catching way, the rider is timely informed of the tire pressure abnormal information.

[0095] Exhaust process:

[0096] When exhaust is needed (such as too much gas is punched in), the gas detected by the air pressure sensor 10 naturally rises along the straight-line gas flow channel composed of the air inlet bottom shell assembly, the transparent shell assembly, the detection assembly and the top exhaust assembly. This design is based on the principle of fluid mechanics. The straight-line channel reduces the collision between gas molecules and the friction with the pipe wall, ensures the smooth flow of gas, avoids additional pressure loss and air flow disturbance, and ensures the accuracy and stability of detection.

[0097] When the gas reaches the top exhaust assembly, i.e. the valve core 302 at the top of the upper mounting shell 301. The valve core 302 is similar to a one-way valve. When the internal pressure of the device is higher than the outside, the gas pushes the valve core 302 to discharge and return to the outside atmosphere. In the non-exhaust state, the valve core 302 is tightly closed to prevent foreign matter from flowing into the device, and to maintain the stability of the internal environment of the device. The third connecting thread 303 on the inner wall of the upper mounting shell 301 is stably connected with the transparent shell assembly, ensuring the sealing of the entire gas channel and ensuring the orderly progress of the exhaust process, and ending the complete gas circulation detection process.

[0098] Although the embodiments of the present application have been shown and described, it will 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.
