Description

Technical Field

[0001] The present invention relates to the technical field of tire pressure monitoring, and in particular to a tire pressure monitoring mechanism. Background Art

[0002] Insufficient tire pressure can cause shoulder wear and shorten tire life. Besides causing the tire to bulge outward and sit closer to the ground, making it more susceptible to damage, insufficient tire pressure can also cause severe deformation and a rapid rise in internal temperature, leading to crown peeling and shoulder wear. This shortens tire life and can also cause standing waves, leading to tire overheating and potentially a blowout. Therefore, excessive tire pressure directly impacts a vehicle's reliability, power, roadworthiness, braking, handling stability, comfort, fuel economy, tire durability, and driving safety.

[0003] Although existing cars are generally equipped with tire pressure monitoring sensors, the existing tire pressure monitoring sensors are generally installed in the tires at the factory, which makes it very inconvenient to disassemble and maintain them. Therefore, the existing technology has certain limitations. Summary of the Invention

[0004] The present invention is made to solve the above-mentioned problem, and its purpose is to provide a tire pressure monitoring mechanism.

[0005] The present invention provides a tire pressure monitoring mechanism, which is arranged on the valve core of the tire and has the following characteristics: a jacket protection assembly, including a fixing bracket and a protection tube, the fixing bracket is annular and is sleeved on the valve core, the protection tube is arranged on the fixing bracket and sleeved on the outer periphery of the valve core, the outer diameter of the protection tube opening is no greater than the outer diameter of the fixing bracket, and the inner diameter is greater than the outer diameter of the valve core, the outer wall of the valve core is provided with a pressure hole connected to the inner cavity of the protection tube, and the protection tube is transparent.

[0006] The air pressure monitoring component is arranged inside the protective tube. The air pressure monitoring component includes a pressure rubber pad, a first pressure display component, a second pressure display component, and an elastic component. The pressure rubber pad is slidably arranged in the protective tube. The first pressure display component is arranged on the pressure rubber pad. The second pressure display component is arranged in the protective tube and is located above the first pressure display component. The distance from the top end of the second pressure display component to the bottom end of the pressure rubber pad is smaller than the distance from the top wall of the protective tube to the valve core. One end of the elastic component is connected to the first pressure display component, and the other end is connected to the second pressure display component.

[0007] When the tire pressure is normal, the first pressure display element can be seen through the protective tube; when the tire pressure is lower than normal, only the second pressure display element can be seen through the protective tube.

[0019] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is described in detail in the following embodiments with reference to the accompanying drawings.

[0020] Example

[0021] Figure 1 It is a front view of the present invention, Figure 2 is a partial cross-sectional view of the present invention, Figure 3 It is a structural diagram of the pressure rubber pad in the present invention.

[0022] like Figures 1 to 3 As shown, this embodiment provides a tire pressure monitoring mechanism, which is arranged on the valve core of the tire and includes a jacket protection component 10 and a pressure monitoring component 20.

[0023] like Figure 1 and Figure 2 As shown, the outer sleeve protection assembly 10 includes a fixed bracket 11 and a protective tube 12. The fixed bracket 11 is annular and is mounted on the valve core. The protective tube 12 is provided on the fixed bracket 11 and is mounted on the outer periphery of the valve core. The outer wall of the valve core is provided with a pressure hole 13 connected to the inner cavity of the protective tube 12. The outer diameter of the tube mouth of the protective tube 12 is not larger than the outer diameter of the fixed bracket 11, and the inner diameter is larger than the outer diameter of the valve core. The protective tube 12 is a transparent protective tube 12.

[0024] In this embodiment, a sealing gasket 14 is provided between the protection tube 12 and the fixing bracket 11 .

[0025] In this embodiment, the height of the protective tube 12 is greater than the distance from the fixing bracket 11 to the valve core.

[0026] In this embodiment, one end of the pressure hole 13 is communicated with the inner cavity of the valve core, and the other end is communicated with the inner cavity of the protection tube 12 .

[0027] like Figure 2 and Figure 3 As shown, the air pressure monitoring assembly 20 is disposed within the protective tube 12 and includes a pressure rubber pad 21, a first pressure indicator 22, a second pressure indicator 23, and an elastic member 24. The pressure rubber pad 21 is slidably disposed within the protective tube 12. The first pressure indicator 22 is disposed on the pressure rubber pad 21. The second pressure indicator 23 is disposed within the protective tube 12 and above the first pressure indicator 22. The distance from the top of the second pressure indicator 23 to the bottom of the pressure rubber pad 21 is less than the distance from the top wall of the protective tube 12 to the valve core. One end of the elastic member 24 is connected to the first pressure indicator 22, and the other end is connected to the second pressure indicator 23. When the tire pressure is normal, the first pressure indicator 22 is visible through the protective tube 12; when the tire pressure is below normal, only the second pressure indicator 23 is visible through the protective tube 12.

[0028] In this embodiment, the top wall of the rubber seal 14 has a mounting groove for mounting the first pressure indicator 22. Both the first and second pressure indicators 22 and 23 have raised portions for the elastic member 24 to fit over. This ensures a secure connection between the pressure rubber seal 21, the first and second pressure indicators 22 and 23, and the elastic member 24, thereby ensuring stability during use.

[0029] In this embodiment, a slip ring 25 is provided on the outer periphery of the pressure rubber pad 21. The outer diameter of the slip ring 25 is equal to the inner diameter of the protective tube 12. The outer wall of the slip ring 25 and the inner wall of the protective tube 12 are both smooth, thereby ensuring that the pressure rubber pad 21 slides smoothly within the protective tube 12.

[0030] In this embodiment, the elastic member 24 is preferably a spring.

[0031] In this embodiment, the outer wall of the first pressure display element 22 is coated with a green coating, and the outer wall of the second pressure display element 23 is coated with a red coating, so that the tire pressure can be better judged during use.
