Abstract
Description
Technical Field
[0001] The invention relates to the technical field of air pressure detection, and in particular to a straight-row, straight-tube flashing-light tire pressure monitoring device for non-motor vehicles. Background Art
[0002] In today's short-distance travel, bicycles and electric vehicles have become popular choices for daily commuting and leisure exercise due to their convenience and environmental protection. Tires are key components that come into contact with the ground. Whether the tire pressure is in a proper state has a vital impact on riding safety, comfort, and energy efficiency (for electric vehicles).
[0003] Traditional tire pressure monitoring technology has presented different forms and problems when applied to the automotive field. Similarly, when considering adapting it to bicycles and electric vehicles, the limitations of the original technology become increasingly prominent. On the one hand, the indirect tire pressure monitoring system relies on wheel speed sensors to indirectly calculate tire pressure. In the relatively simple electronic control systems of bicycles and electric vehicles, it is difficult to achieve accurate wheel speed comparison and analysis. Moreover, since the driving speeds of these two types of vehicles are usually lower than those of cars, the sensitivity of wheel speed changes to tire pressure is lower, and the detection accuracy is difficult to meet actual needs. For example, when a bicycle tire has a slight slow leak and the air pressure slowly drops, the indirect system often cannot detect it in time. It may not be detected until the rider obviously feels that riding is difficult, or even when the tire has been deflated to seriously affect the control, which undoubtedly buries a safety hazard in the riding process.
[0004] On the other hand, in terms of gas flow stability, since the vibration frequency and amplitude of bicycles and electric vehicles during riding are different from those of cars, the side air intake method is more likely to cause gas turbulence in the detection area and interfere with the operation of the detection elements. For example, when passing through bumpy roads, the violent vibration of the vehicle will make the originally unstable side airflow even more complicated, causing frequent fluctuations in the detection results and failing to provide accurate and continuous tire pressure information for the rider. Furthermore, considering that bicycles and electric vehicles are often parked in the open air and face more rain and dust, the multi-sealed connection parts of the side air intake design are extremely susceptible to damage. Once the seal is not tight, rainwater infiltration may directly damage the detection elements and shorten the service life of the device. Frequent repairs and replacements are both costly and labor-intensive.
[0005] Therefore, we propose a straight-row, straight-tube, flashing-light tire pressure monitoring device for non-motor vehicles. Summary of the invention
[0006] The purpose of the present invention is to solve the shortcomings existing in the prior art. In terms of gas flow stability, since the vibration frequency and amplitude of bicycles and electric vehicles during riding are different from those of cars, the side air intake method is more likely to cause gas turbulence in the detection area and interfere with the operation of the detection element. For example, when passing through bumpy roads, the violent vibration of the vehicle will make the originally unstable side airflow more complicated, causing frequent fluctuations in the detection results and failing to provide accurate and continuous tire pressure information for the rider. Furthermore, considering that bicycles and electric vehicles are often parked in the open air and face more rain and dust invasion, the multi-sealed connection parts of the side air intake design are extremely susceptible to damage. Once the seal is not tight, rainwater infiltration may directly damage the detection element and shorten the service life of the device. Frequent maintenance and replacement are both costly and labor-intensive.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[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 1-6 As shown, the present invention provides a technical solution: a straight-row flashing light tire pressure monitoring device for a non-motor vehicle, comprising: an air intake bottom shell assembly directly connected to the tire valve, the air intake bottom shell assembly is used to receive the 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 intake bottom shell assembly fits tightly with the tire valve to ensure that the gas in the tire can flow into the device smoothly and unimpeded. The principle is to minimize the pressure loss during gas transmission by closely docking with the valve, and ensure that the gas sample used in subsequent tests can truly reflect the air pressure in the tire. For example, during bicycle riding, as the road is bumpy, the gas in the tire may produce instantaneous high or low pressure fluctuations. If the air intake link is blocked or unstable, the air pressure transmitted to the device will deviate, resulting in inaccurate test results. This directly connected design is like opening up a "highway" for the gas to allow it to enter smoothly.
[0051] When the tire is inflated and put into use, the gas naturally flows to the intake pan assembly directly connected to the valve due to the pressure inside the tire, ready to enter the subsequent inspection process.
[0052] A transparent shell assembly is provided at the connection of the air intake bottom shell assembly, a detection assembly is provided inside the transparent shell assembly, and an air pressure sensor 10 for detecting gas pressure is installed at the bottom of the detection assembly and at the end of the air intake bottom shell assembly.
[0053] The transparent shell component plays a dual role of protection and visualization. On the one hand, it provides a relatively closed and stable environment for the internal detection component to resist 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 internal components, such as flashing red and green lights 13. The air pressure sensor 10 of the detection component is a key link. It works based on the principle of pressure and electrical signal conversion, that is, when the gas pressure acts on the sensor's sensing element, it will cause physical deformation of the element, which is then converted into corresponding electrical signal changes. These electrical signals are transmitted to the subsequent circuit for analysis and processing.
[0054] After the gas flows from the air intake bottom shell assembly into the transparent shell assembly, it is immediately captured by the air pressure sensor 10 located at the bottom end. The air pressure sensor 10 converts the air pressure in the tire into an electrical signal in real time and transmits it to other circuit modules in the detection assembly. Under normal circumstances, the pressure sensor will continue to detect the gas in the tire to ensure that the tire pressure status can be grasped in real time.
[0055] A top exhaust assembly connected to the transparent shell assembly is provided on the top of the device, and is used to exhaust the detected gas. The air intake bottom shell assembly, the transparent shell assembly, the detection assembly and the top exhaust assembly form a linear gas flow channel to achieve direct entry and exhaust of the gas and ensure the accuracy and stability of the detection.
[0056] The linear gas flow channel is designed based on the principles of fluid mechanics. In a continuous, unbending channel, the gas flow is smoother and turbulence is not easy to form. Compared with curved or complex structure channels, the straight type can reduce the collision between gas molecules and the friction with the tube wall, avoiding additional pressure loss and airflow disturbance. This not only ensures the accuracy of the data collected by the air pressure sensor 10, but also makes the entire detection process efficient and stable. It is like running water in a straight water pipe, the water flow velocity is uniform and the pressure is stable; in a curved water pipe, the water flow is prone to vortexes and uneven flow velocity, which affects the accuracy of water pressure measurement.
[0057] When manually deflated, the gas naturally rises along the linear channel and reaches the top exhaust assembly, that is, 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 air pressure inside the device is higher than that outside, the gas pushes the valve core 302 open and is discharged, returning to the outside atmospheric environment, so that the air pressure inside the tire gradually returns 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, and the third connecting thread 303 on the inner wall of the upper mounting shell 301 is firmly connected to the transparent shell assembly to ensure the sealing of the entire gas channel and prevent external impurities from flowing back into the device.
[0058] The air intake bottom shell assembly includes a lower mounting shell 201 , a gas nozzle joint 202 is provided at the bottom of the lower mounting shell 201 , a vent hole 203 is opened inside the lower mounting shell 201 , and a second connecting thread 204 is provided on the outer side of the lower mounting shell 201 .
[0059] The lower mounting shell 201 is the main structure of the air intake bottom shell assembly. The air nozzle joint 202 is the "interface" that directly docks with the tire valve. Its sophisticated design ensures a tight fit with the valve to prevent air leakage. The vent 203 provides an internal channel for gas to enter, allowing the gas entering from the valve to flow smoothly to subsequent components. The second connecting thread 204 on the outside is used to connect with other components, such as a transparent shell assembly. The threaded connection method 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 air valve joint 202 is screwed and fixed to the tire valve during initial installation, and the gas in the tire enters the vent 203 inside the lower mounting shell 201 through the air valve joint 202 to provide an air source for subsequent detection; when the device needs to be maintained or parts need to be replaced, the lower mounting shell 201 can be easily unscrewed using the second connecting thread 204.
[0061] The transparent shell assembly comprises an outer transparent shell 101 . A first connecting thread 102 is provided on the inner wall of the outer transparent shell 101 and at both ends. An inner protective transparent shell 7 is also provided inside the outer transparent shell 101 .
[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 intake bottom shell assembly and the top exhaust assembly to build a complete gas channel. The inner protective transparent shell 7 provides secondary protection for the internal detection components to prevent the external fine dust, water vapor and other impurities from breaking through the outer transparent shell 101 and causing damage to the precise detection components, while not affecting visual observation. It is a multi-layer protection and practical design.
[0063] During operation, the outer transparent shell 101 utilizes the first connecting thread 102 to dock with the lower mounting shell 201 and the upper mounting shell 301 respectively to ensure the sealing of the gas channel; the inner protective transparent shell 7 always guards the internal PCB circuit board 5 and other detection components, and can maintain the normal working environment of the detection components as much as possible even in harsh environments.
[0064] The detection component includes a PCB circuit board 5 , on which an MCU 11 , a power module 12 and a flashing red light 13 are respectively mounted. The MCU 11 , the power module 12 and the flashing red light 13 are all electrically connected to the PCB circuit board 5 .
[0065] The PCB circuit board 5 serves as a carrier platform and integrates multiple key functional modules. The MCU11 (microcontroller unit) is the "intelligent core" of the entire detection system. It receives the electrical signal from the air pressure sensor 10, analyzes and processes the data according to the preset program algorithm, and determines whether the tire pressure is within the normal range. The power module 12 provides stable power support for the entire detection component to ensure the normal operation of each component. The flashing red and green lights 13 are intuitive warning devices. When the MCU11 determines that the tire pressure is abnormal, it controls the red and green lights to flash at a specific frequency to alert the rider.
[0066] Here is a detailed description of the operating principle from detection to flashing lights: When the air pressure sensor 10 converts the gas pressure in the tire into an electrical signal and transmits it to MCU11, the high-precision A / D (analog / digital) converter built into MCU11 first digitizes the electrical signal and converts it into a digital signal for subsequent calculation and analysis. MCU11 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. MCU11 compares the received digitized air pressure value with the corresponding standard tire pressure range in real time. Once it is detected that the air pressure value exceeds the standard range, whether it is higher than the upper limit (which may indicate that the tire is over-inflated and there is a risk of a blowout) or lower than the lower limit (which means that the tire may have a slow leak), MCU11 will immediately start the warning program.
[0067] When the warning program is started, MCU11 will send control instructions to the drive circuit connected to the flashing red light 13 according to the preset logic. This drive circuit is generally a power amplifier circuit composed of electronic components such as transistors and resistors. It can amplify the weak control signal output by MCU11 to provide sufficient current to drive the flashing red light 13 to work. After receiving the instruction from MCU11, the drive circuit provides intermittent power supply to the flashing red light 13 according to the established frequency and mode, so that the red light lights up at a specific flashing frequency, such as fast flashing red light indicates serious low pressure danger, slow flashing yellow light indicates slight low pressure or high pressure warning, etc., so as to intuitively convey abnormal tire pressure information to the rider.
[0068] In daily operation, MCU11 continuously receives data from the air pressure sensor 10, and the power module 12 provides uninterrupted power supply to ensure that the entire detection system is always on standby. Once the tire pressure exceeds the normal range, MCU11 immediately drives the flashing red light 13 to send a warning signal, and the rider can see it clearly through the transparent shell.
[0069] The top exhaust assembly comprises an upper mounting shell 301 , a valve core 302 is arranged on the top of the upper mounting shell 301 , and a third connecting thread 303 is arranged on the inner wall of the upper mounting shell 301 .
[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 air pressure inside the device is higher than that outside, when the exhaust conditions are met, the gas can push open the valve core 302 to be discharged; in the non-exhaust state, the valve core 302 is tightly closed to prevent external impurities from flowing back into the device. The third connecting thread 303 on the inner wall is used to firmly connect with the transparent shell assembly to ensure the sealing of the entire gas channel. This is also a manifestation of mechanical connection to ensure sealing and functionality.
[0071] During operation, the valve core 302 is normally closed to maintain a stable internal environment of the device; when tire leakage causes exhaust demand, the detected gas is pushed open by the internal pressure of the device to push the valve core 302 out, and the third connecting thread 303 ensures that the upper mounting shell 301 is tightly matched with the transparent shell to prevent air leakage.
[0072] The upper mounting shell 301 and the outer transparent shell 101 are threadedly connected via the third connecting thread 303 and the first connecting thread 102 , and a second sealing gasket 8 is provided at the connection.
[0073] The threaded connection provides basic connection strength, ensuring that the upper mounting shell 301 and the outer transparent shell 101 will not loosen or separate under various riding vibration environments. The second sealing pad 8, as an auxiliary sealing means, further fills the tiny gaps that may exist in the threaded connection to prevent gas leakage or impurities from penetrating. The double protection improves the overall sealing and reliability of the device, following the mechanical seal 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 pad 8 continues to play a sealing role to ensure the stable operation of the device.
[0075] The lower mounting shell 201 is threadedly connected to the first connecting thread 102 of the outer transparent shell 101 through the vent hole 203, and a third sealing gasket 9 is provided at the connection.
[0076] This situation is similar to the connection between the upper mounting shell 301 and the outer transparent shell 101. The threaded connection ensures the stability of the structure, and the vent hole 203 allows the gas to transfer smoothly. The third sealing pad 9 focuses on strengthening the seal of the connection of the air intake link to prevent the high-pressure gas in the tire from leaking here and affecting the detection accuracy, because even a small amount of gas leakage may cause the pressure value collected by the air pressure sensor 10 to be low, giving an erroneous normal tire pressure signal.
[0077] During operation, the lower mounting shell 201 is tightly matched with the outer transparent shell 101 by means of threaded connection, and the third sealing gasket 9 blocks gas leakage, ensuring that the gas flows completely from the tire into the subsequent detection process.
[0078] A plurality of storage batteries 6 are also arranged inside the inner protective transparent shell 7 , and the plurality of storage 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 to the detection component to maintain the continuous operation of the tire pressure monitoring function.
[0080] A sealing plate 14 is further provided at the bottom of the inner protective transparent shell 7 , and a first sealing gasket 4 is further provided between the sealing plate 14 and the inner protective transparent shell 7 .
[0081] The sealing plate 14 provides a closed protection for the bottom of the inner protective transparent shell 7 to prevent dust, water vapor, etc. from invading from the bottom. The first sealing gasket 4 further strengthens the sealing effect between the sealing plate 14 and the inner protective transparent shell 7, and together with other sealing gaskets, builds a comprehensive protection system to protect the internal detection components. Even if you ride on a flooded road in rainy days or park in the open air for a long time, it can minimize the damage to the device caused by adverse external factors.
[0082] During the service life of the device, the sealing plate 14 and the first sealing gasket 4 always stay in place to block external impurities and ensure the cleanliness and stability of the internal environment of the inner protective transparent shell 7.
[0083] like Figure 6 As shown, it is a schematic diagram of the connection of the beautiful nozzle.
[0084] Gas entry process:
[0085] During initial installation, the air valve connector 202 at the bottom of the lower mounting shell 201 of the air intake bottom shell assembly is tightly screwed and fixed to the tire valve to ensure 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 under pressure flows smoothly into the vent 203 opened inside the lower mounting shell 201 through the "entrance" of the gas nozzle joint 202, and then flows into the entire device to provide gas source for subsequent testing. This process is due to the precise adaptation design of the gas nozzle joint 202 and the valve, as well as the reasonable layout of the vent 203, which maximizes the stability and smoothness of gas entry, just like opening a precise and stable "raw material supply gate" for the subsequent testing process.
[0087] Testing process:
[0088] After the gas flows from the air intake bottom shell assembly into the transparent shell assembly connected thereto, it is immediately captured by the air pressure sensor 10 located inside the transparent shell assembly and at the end of the air intake bottom shell assembly.
[0089] The air pressure sensor 10 works based on the principle of pressure and electrical signal conversion. When the gas pressure acts on its sensing element, it causes the element to physically deform, thereby accurately converting the gas pressure in the tire into an electrical signal in real time.
[0090] The converted electrical signal is quickly transmitted to the PCB circuit board 5 in the detection component. The PCB circuit board 5 serves as the core carrier platform of the entire detection system, and the MCU11 (microcontroller unit) installed on it plays a key role in data processing. MCU11 has a built-in high-precision A / D (analog / digital) converter, which first digitizes the received electrical signal for subsequent complex calculation and analysis. At the same time, MCU11 pre-stores the standard tire pressure range values that are carefully optimized and set for different types of non-motor vehicles (such as bicycles, electric vehicles, etc.). These values are derived from a large number of experimental tests and actual riding data collection. MCU11 continuously compares the received digitized air pressure value with the corresponding standard tire pressure range in real time, like a rigorous "data judge", always monitoring whether the tire pressure is normal.
[0091] Warning process (when tire pressure is abnormal):
[0092] Once MCU11 detects that the air pressure value exceeds the standard range, whether it is higher than the upper limit (meaning that the tire is over-inflated and there is a risk of blowout) or lower than the lower limit (indicating that the tire may have a slow leak), MCU11 will immediately start the warning program according to the preset logic.
[0093] When the warning program is started, the MCU 11 sends a control instruction to the drive circuit connected to the flashing red 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 the flashing red light 13 with sufficient current to drive it to work.
[0094] After receiving the instruction from MCU11, the driving circuit provides intermittent power supply to the flashing traffic light 13 according to the established frequency and mode, so that the traffic light lights up at a specific flashing 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 deal with the tire pressure problem at the right time. In this intuitive and eye-catching way, abnormal tire pressure information is conveyed to the rider in a timely manner.
[0095] Exhaust process:
[0096] When exhaust and deflation are required (e.g. too much gas is injected), the gas detected by the air pressure sensor 10 naturally rises along the linear gas flow channel composed of the intake bottom shell component, the transparent shell component, the detection component and the top exhaust component. This design is based on the principle of fluid mechanics. The linear 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 airflow disturbance, and ensures the accuracy and stability of detection.
[0097] The gas reaches the top exhaust assembly, that is, 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 air pressure of the device is higher than that of the outside, the gas pushes the valve core 302 open and is discharged to return to the outside atmosphere. In the non-exhaust state, the valve core 302 is tightly closed to prevent external impurities from flowing back into the device and 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 firmly connected to the transparent shell assembly to ensure the sealing of the entire gas channel and ensure that the exhaust process proceeds in an orderly manner, bringing a complete gas circulation detection process to a full stop.
[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.
