Description

Technical Field

[0001] This utility model relates to the field of safety monitoring, and more specifically, to a tire pressure detector. Background Technology

[0002] As a key component in contact with the ground, tires' performance directly affects the safety and stability of vehicle operation. Among the many factors influencing tire performance, maintaining proper tire pressure plays a crucial role. Excessive tire pressure reduces the contact area between the tire and the ground, leading to uneven tire wear and decreased vehicle handling, making effective braking and steering difficult in emergencies. Conversely, insufficient tire pressure exacerbates tire deformation, damages the internal structure, generates excessive heat during driving, and significantly increases the risk of tire blowout. Therefore, accurate and real-time monitoring of tire pressure is of paramount importance for preventing traffic accidents and ensuring safe vehicle operation.

[0003] The existing technology still has the following drawbacks:

[0004] (1) It is impossible to monitor tire pressure during driving, making it difficult to detect sudden air leaks or abnormal pressure in time.

[0005] (2) When the detector alarms that the tire pressure is too low, the user needs to manually find an inflation device. In remote areas or at night, it may not be possible to replenish the air in time, resulting in the tire running under low pressure and causing damage to the tire.

[0006] Therefore, a tire pressure testing instrument is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a tire pressure monitoring device to address the current problem of not being able to monitor tire pressure during driving and the difficulty in timely detecting sudden air leaks or abnormal pressure, thereby solving the problems mentioned in the background art.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] The present invention is as follows: a tire pressure tester, including a valve core, on which a pressure detection component is fixedly installed, one end of the pressure detection component is connected to an annular monitoring module, an inflation component is fixedly installed on one side of the annular monitoring module, and a fixing component is connected to the top of the annular monitoring module.

[0010] The air pressure detection assembly includes a conversion connector fixedly connected to one end of the valve core. A sealing gasket is provided on the conversion connector, and a pressure sensor is fixedly installed on the sealing gasket. A conduit is fixedly connected to one end of the pressure sensor, and a sealing interface is fixedly installed at one end of the conduit. The sealing interface is fixed to the annular monitoring module by bolts.

[0011] As a preferred technical solution of this utility model, the inflation assembly includes a miniature inflation tank located on one side of the annular monitoring module. An air outlet is fixedly installed on one side of the miniature inflation tank. An air pipe is movably connected to one end of the air outlet. The air pipe and the air outlet are connected by a thread. An air inlet is fixedly connected to the other end of the air pipe. A pressure regulating valve is provided at the bottom of the air inlet. The pressure regulating valve is located at the top of the conduit. The conduit and the pressure regulating valve are fixed together by bolts.

[0012] As a preferred technical solution of this utility model, the fixing component includes a fastening band located at the top of the annular monitoring module and the miniature inflatable tank. The fastening band has a positioning hole, and an adjustable positioning bolt is provided in the positioning hole. An anti-detachment claw is fixedly installed on one side of the fastening band, and the anti-detachment claw is symmetrically distributed on both sides of the fastening band.

[0013] As a preferred technical solution of this utility model, heat insulation layers are fixedly installed on the inner side of both the annular monitoring module and the micro inflatable tank, and shock-absorbing pads are provided on the heat insulation layers, with two sets of shock-absorbing pads evenly distributed.

[0014] As a preferred technical solution of this utility model, an audible and visual alarm is provided on one side of the ring monitoring module, and the audible and visual alarm is electrically connected to the ring monitoring module.

[0015] As a preferred technical solution of this utility model, the ring monitoring module is provided with a battery device, which is located at the bottom of the fastening band.

[0016] As a preferred technical solution of this utility model, the ring monitoring module is equipped with a pressure display, which is located on one side of the pressure regulating valve and is electrically connected to the pressure regulating valve.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By using the set air pressure detection component, the adapter is tightened clockwise onto the tire valve core according to different tire models. The device automatically turns on when it is fully rotated, eliminating the need for cumbersome on / off operation. After startup, the pressure sensor collects the air pressure change data inside the tire in real time. The air pressure data is transmitted at high speed to the ring monitoring module through the conduit. The center of the conduit is the inflation channel, and the tube wall is embedded with miniature data wires. Inflation and signal transmission are completely isolated and do not interfere with each other. The device monitors the tire air pressure in real time, avoiding damage to the tire and sudden danger to the driver caused by excessively low or high tire pressure. This solves the problem of existing technologies that cannot monitor tire pressure during driving and are difficult to detect sudden air leaks or abnormal pressure in time.

[0019] 2. Through the specially designed inflation component, when the system detects that the tire pressure is lower than the preset safety value via the pressure sensor, compressed gas is first steadily output from the outlet of the miniature inflation canister, and then enters the high-pressure resistant air pipe through the leak-proof threaded interface. Subsequently, the gas flows rapidly in the air pipe and is injected into the tire through the inlet. The pressure regulating valve precisely controls the entire process, and through real-time monitoring, it accurately calculates how much gas needs to be inflated, avoiding the impact of insufficient inflation on driving safety and preventing damage to tire performance due to over-inflation. This solves the problem in existing technologies where, when the pressure gauge alarms that the tire pressure is too low, the user has to manually find an inflation device, which may not be possible in remote areas or at night, leading to the tire running under continuous low pressure and causing tire damage.

[0030] like Figures 1-4 As shown, this embodiment proposes a tire pressure tester, including a valve core 1, a tire pressure detection component 2 fixedly installed on the valve core 1, an annular monitoring module 3 connected to one end of the tire pressure detection component 2, an inflation component 4 fixedly installed on one side of the annular monitoring module 3, and a fixing component 5 connected to the top of the inflation component 4 and the annular monitoring module 3.

[0031] The tire pressure detection component 2 includes a conversion connector 201 fixedly connected to one end of the valve core 1. A sealing gasket 202 is provided on the conversion connector 201, and a pressure sensor 203 is fixedly mounted on the sealing gasket 202. One end of the pressure sensor 203 is fixedly connected to a conduit 204, and one end of the conduit 204 is fixedly mounted with a sealing interface 205. The sealing interface 205 is fixed to the annular monitoring module 3 by bolts. In use, the conversion connector 201 is tightened clockwise onto the tire valve core 1 according to the different tire models. Once fully tightened, the module automatically starts, eliminating the need for cumbersome on / off operations. After startup, the pressure sensor 203 collects real-time tire pressure change data and transmits the pressure data at high speed to the annular monitoring module 3 through the conduit 204. The center of the conduit 204 is an inflation channel with miniature data wires embedded in the tube wall, ensuring complete isolation and non-interference between inflation and signal transmission. This allows for real-time monitoring of tire pressure, preventing damage to the tire and potential hazards to drivers caused by excessively low or high tire pressure.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the inflation assembly 4 includes a miniature inflation tank 401 located on one side of the annular monitoring module 3. An air outlet 402 is fixedly installed on one side of the miniature inflation tank 401. One end of the air outlet 402 is movably connected to an air pipe 403. The air pipe 403 and the air outlet 402 are connected by a thread. The other end of the air pipe 403 is fixedly connected to an air inlet 404. A pressure regulating valve 405 is provided at the bottom of the air inlet 404. The pressure regulating valve 405 is located at the top of the conduit 204. The conduit 204 and the pressure regulating valve 405 are fixed together by bolts. When the system detects that the tire pressure is lower than the preset safety value through the pressure sensor 203, compressed gas is first steadily output from the outlet 402 of the miniature air canister 401, and enters the high-pressure resistant air pipe 403 through the leak-proof threaded interface; then the gas flows rapidly in the air pipe 403 and is injected into the tire through the air inlet 404. The pressure regulating valve 405 precisely controls the entire process. Through real-time monitoring, it accurately calculates how much gas needs to be injected, avoiding driving safety due to insufficient inflation and preventing damage to tire performance due to over-inflation.

[0033] like Figures 1-3 As shown, the fixing component 5 includes a fastening band 501 located at the top of the annular monitoring module 3 and the miniature air tank 401. The fastening band 501 has a positioning hole 502, and an adjustable positioning bolt 503 is installed inside the positioning hole 502. An anti-detachment claw 504 is fixedly installed on one side of the fastening band 501, and the anti-detachment claws 504 are symmetrically distributed on both sides of the fastening band 501. During installation, the fastening band 501 is placed on the wheel hub, the positioning bolt is adjusted and tightened, and the claws engage with the edge of the wheel hub, providing double security and adapting to different wheel hub sizes to ensure it does not loosen during driving.

[0034] like Figures 1-3 and Figure 5 As shown, heat insulation layers 6 are fixedly installed on the inner sides of both the annular monitoring module 3 and the miniature air tank 401. Two sets of shock-absorbing pads 7 are evenly distributed on the heat insulation layer 6. The heat insulation layer 6 prevents high brake temperatures from affecting electronic components, while the shock-absorbing pads 7 absorb tire vibrations, effectively protecting the annular monitoring module 3 and the miniature air tank 401.

[0035] like Figures 1-3 and Figure 5 As shown, an audible and visual alarm 8 is installed on one side of the ring monitoring module 3, and the audible and visual alarm 8 is electrically connected to the ring monitoring module 3. When the pressure sensor 203 detects an abnormality, the alarm immediately flashes and sounds, reminding the driver to take timely action and avoid the risk of tire blowout due to tire pressure problems.

[0036] like Figures 1-3 and Figure 5 As shown, the ring monitoring module 3 is equipped with a battery device 9, which is located at the bottom of the fastening strap 501. The battery device 9 powers the entire system, is rechargeable or replaceable, ensuring long-term use and reducing frequent charging.

[0037] like Figures 1-3 and Figure 5 As shown, the ring monitoring module 3 is equipped with a tire pressure display 10, which is located on one side of the pressure regulating valve 405. The tire pressure display 10 is electrically connected to the pressure regulating valve 405. The tire pressure display 10 displays the tire pressure in real time, and the pressure regulating valve 405 automatically adjusts the inflation amount based on the data. The vehicle owner can view the tire pressure through the display, and the system can automatically or manually adjust the tire pressure to maintain the optimal tire pressure.

[0038] Specifically, when using this tire pressure gauge: Secure the fastening strap 501 onto the wheel hub, adjust and tighten the positioning bolt, and engage the chuck around the edge of the wheel hub. Depending on the tire model, screw the adapter 201 clockwise onto the tire valve core 1. Once fully engaged, the device automatically powers on, eliminating the need for cumbersome on / off operations. After startup, the pressure sensor 203 collects real-time data on tire pressure changes and transmits this data at high speed to the annular monitoring module 3 via the conduit 204. The conduit 204 has an inflation channel at its center, with miniature data wires embedded in its wall, ensuring complete isolation and non-interference between inflation and signal transmission. The system monitors tire pressure in real time. When the pressure sensor 203 detects that the tire pressure is lower than the preset safety value, the tire pressure display 10 displays the tire pressure in real time. The pressure regulating valve 405 automatically adjusts the inflation amount according to the data. Compressed gas is first output smoothly from the outlet 402 of the miniature air canister 401 and enters the high-pressure resistant air pipe 403 through the leak-proof threaded interface. Then the gas flows rapidly in the air pipe 403 and is injected into the tire through the air inlet 404. The pressure regulating valve 405 precisely controls the entire process and accurately calculates how much gas needs to be inflated through real-time monitoring.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
