[0027] The function of the valve is to inflate and deflate the tire and maintain the seal after the tire is inflated. Traditional valves are divided into two types: vertically installed on the wheel hub or tilted installed on the wheel hub. The sensor of the valve installed vertically on the wheel hub is in a vertical state, while the sensor is also tilted when the valve is tilted on the wheel hub.

[0028] The tilted setting of the wheel hub opening can reduce the risk of sensor damage. If a valve nozzle installed vertically on the wheel hub is used, the sensor will be tilted. However, the tilted sensor may be crushed by its own gravity after the wheel hub is deflated, resulting in the inability to accurately detect the tire pressure in the tire through the sensor.

[0029] In order to solve this technical problem, the utility model provides a valve nozzle installed on a wheel hub with an oblique side opening and simultaneously performing tire pressure detection. The valve nozzle is used to be installed in a groove in the wheel hub, and a through hole is opened at the bottom of the groove, and the through hole is arranged relatively inclined to the bottom of the groove.

[0030] See also Figure 1 to Figure 2 The valve comprises: a valve body 10 , a sensor 30 and a protective member 40 .

[0031] The valve body 10 forms an air inflating passage 12 with two openings along its extension direction to allow external gas to enter the wheel hub 20. One end of the valve body 10 is used to be inserted into the through hole. The end of the valve body 10 located in the wheel hub 20 is formed with an inclined surface 11. The inclined surface 11 is inclined in a direction from one end of the valve body close to the through hole to the other end in a direction away from the groove bottom.

[0032] The sensor 30 is mounted on the inclined surface 11 and is perpendicular to the bottom surface of the groove; and

[0033] The protective member 40 is mounted on the other end of the valve body 10 and blocks the other opening of the inflation airway.

[0034] The valve assembly of the utility model includes a valve body 10, a sensor 30 and a protective member 40. An inclined surface 11 is provided at one end of the valve body 10. The inclined surface 11 extends from one side of the end of the valve body close to the through hole to the other side and extends in a direction away from the through hole. The valve body 10 penetrates the through hole opened at the bottom of the groove in the wheel hub 20, and at the same time ensures that the sensor 30 matches the groove in the wheel hub 20.

[0035] The valve body 10 is provided with an air inflating passage 12 along its extension direction. The air inflating passage 12 has two openings, one opening is located on a side close to the inclined surface 11, and the other opening is formed on the end surface of the valve body 10 located outside the wheel hub 20. The setting of the air inflating passage allows external gas to smoothly pass into the wheel hub 20, which is convenient for tire inflation.

[0036] The sensor 30 is mounted on the inclined surface 11 and is located in the groove. This arrangement enables the sensor 30 to accurately sense the air pressure changes in the tire, and effective tire pressure detection can be performed even on a wheel hub with an inclined side opening. The horizontal position of the sensor 30 ensures the accuracy of tire pressure reading and is not affected by the inclination angle of the wheel hub opening.

[0037] The protective member 40 is installed at the other end of the valve body 10. Its function is to block the other opening of the inflation airway 12 to prevent foreign matter from entering the airway, prevent gas from escaping, and protect the end of the valve body 10 from damage. The setting of the protective member 40 ensures the overall sealing and durability of the valve assembly.

[0038] Combination Figure 1 and Figure 2 As shown, in the embodiment of the present utility model, the sum of the inclination angle of the inclined surface 11 relative to the end surface of the valve body and the angle between the axis in the extension direction of the valve body 10 and the horizontal plane is equal to 90°.

[0039] In this embodiment, the sum of the inclination angle of the inclined surface 11 and the axial inclination angle of the valve body 10 is controlled to be equal to 90°.

[0040] The setting of the inclined surface 11 enables the sensor 30 to contact the inner wall of the wheel hub at an optimal angle, thereby improving the sensitivity of the sensor 30 to changes in tire pressure. The inclined angle ensures that the sensor 30 will not be misread due to the inclined opening of the wheel hub, thereby ensuring the accuracy of the tire pressure data.

[0041] Furthermore, the inclination angle of the inclined surface 11 is preferably 45°, and the inclination angle of the axis in the extension direction of the valve body 10 is preferably 45°. The inclined surface 11 of the valve body 10 and the axis in the extension direction of the valve body are set to an inclination angle of 45°. The angle of 45° provides an accurate position for the sensor 30, enabling it to maintain optimal horizontal contact with the inner wall of the tire, thereby ensuring the accuracy of the tire pressure reading.

[0042] Furthermore, when the axis and the inclined surface 11 of the valve body 10 are both set at 45°, the 45° angle configuration helps to optimize the spatial relationship between the sensor 30 on the valve body 10 and the wheel hub 20. Such a setting reduces the resistance of gas flow during the inflation or tire pressure detection process of the valve, thereby improving the inflation efficiency.

[0043] Combination Figure 1 and Figure 2 As shown, in the embodiment of the utility model, a protrusion 13 is provided on the extension direction of the valve body 10, an inclined surface 11 is formed on the end surface of the protrusion 13, and an opening of the inflation airway 12 is provided on the side of the valve body away from the groove bottom.

[0044] In this embodiment, a protrusion 13 is protruded in the extension direction of the valve body 10, and the protrusion 31 is integrally formed with the valve body 20. The protrusion 13 is arranged to avoid the air outlet of the inflation air duct 12 while forming an inclined surface, thereby optimizing the flow rate of the intake air and ensuring that the gas in the valve body 10 can smoothly pass through the through hole and enter the wheel hub. The arrangement of the inclined surface 11 on the protrusion 13 also contributes to the stable installation of the sensor 30, which provides a horizontal installation surface for the sensor 30, thereby ensuring the accuracy of tire pressure detection.

[0045] Combination Figure 1 and Figure 2 As shown, in the embodiment of the present invention, a recess 14 is formed on the circumferential side of the valve body 10, the inflation airway 12 is connected to the recess 14, and an opening is formed in the recess 14 to connect the inflation airway and the recess.

[0046] In this embodiment, a recess 14 is provided on the peripheral side of the valve body 10. The recess 14 may be an annular groove surrounding the valve body 10 or a semicircular groove. The inflation air duct 12 is connected with the recess 14, that is, the gas in the inflation air duct 12 can pass through the recess 14, thereby achieving communication with the interior of the wheel hub. The setting of the recess 14 provides the inflation air duct 12 with a channel directly connected with the interior of the wheel hub. Such a setting not only ensures the efficiency of gas circulation, but also helps to optimize the structure of the valve body 10, making it more compact.

[0047] Combination Figure 1and Figure 2 As shown, in the embodiment of the utility model, the sensor 30 is threadedly connected to the inclined surface 11, the sensor 30 defines a connecting hole 31, the inclined surface 11 defines a mounting hole 111, the locking member passes through the connecting hole 31, and is threadedly connected to the mounting hole 111.

[0048] In this example, the threaded connection has good detachability and increases the stability of the connection, which is convenient for maintenance or replacement of the sensor 30 when necessary. When the sensor 30 fails or needs to be upgraded, the technician can quickly disassemble and replace the new sensor without replacing the entire valve assembly, which greatly reduces the maintenance cost.

[0049] The sensor 30 is a tire pressure detection sensor, which is connected to the valve body 10 through the connection hole 31. The connection hole 31 is provided on the sensor 30 to allow the bolt to pass through and connect to the valve body 10. The valve body 10 has a mounting hole 111 on the inclined surface, that is, one end of the inflation airway is open, and the bolt is passed through the connection hole 31 and is threadedly connected to the mounting hole 111, so that the sensor 30 can be firmly connected to the valve body 10. This threaded connection can effectively prevent gas leakage during the inflation process.

[0050] Furthermore, the tire pressure detection sensor can monitor the air pressure in the wheel hub in real time and convert the signal into an electrical signal output for use by other systems of the vehicle. This can not only improve the comfort and safety of the vehicle, but also provide important reference information for vehicle maintenance and fault diagnosis.

[0051] Combination Figure 1 and Figure 2 As shown, in an embodiment of the utility model, the connecting hole includes a first connecting portion and a second connecting portion, the first connecting portion and the second connecting portion are arranged in the axial direction of the connecting hole, the diameter of the first connecting portion is greater than the diameter of the second connecting portion, and the locking piece is sequentially passed through the second connecting portion, the first connecting portion and the mounting hole 111.

[0052] In this embodiment, the connection hole is arranged in a segmented structure, specifically including a first connection part and a second connection part. The two parts are arranged in the axial direction of the connection hole to form a graded connection hole with different diameters. The diameter of the first connection part is set larger than the diameter of the second connection part. Such an arrangement not only provides a more flexible assembly method, but also can adapt to bolts of different sizes, thereby increasing the adaptability of the connection.

[0053] The provision of the first connection portion helps to improve the stability of the threaded connection. The first connection portion enables the sensor to adapt to other different models and types of valve nozzles, so that one end of the valve nozzle can be plugged into the first connection portion and connected to the sensor through threads, thereby increasing the versatility of the sensor.

[0054] Combination Figure 1 and Figure 2 As shown, in an embodiment of the utility model, the valve stem further includes a sealing member 50, which includes a first sealing portion and a second sealing portion connected to each other, wherein the diameter of the first sealing portion is greater than the diameter of the second sealing portion, and the first sealing portion and the second sealing portion are both sleeved on the valve stem body 10, and the outer peripheries of the first sealing portion and the second sealing portion are used to abut against the inner wall of the through hole.

[0055] In this embodiment, the seal 50 is introduced to ensure the sealing between the valve body 10 and the wheel hub 20, prevent gas leakage, and thus ensure the accuracy of tire inflation and tire pressure monitoring. The seal 50 is composed of two connected parts, namely a first sealing part and a second sealing part, which work together to provide a stable sealing system for the valve.

[0056] Furthermore, the diameter of the first sealing portion is set to be larger than the diameter of the second sealing portion, and such a setting allows the first sealing portion and the second sealing portion to be sequentially sleeved on the valve body 10 to form a tight sealing layer. The outer peripheries of the first sealing portion and the second sealing portion abut against the inner wall of the through hole, ensuring that there is no gas leakage at the through hole between the valve body 10 and the wheel hub 20, thereby enhancing the sealing performance of the entire valve assembly.

[0057] Combination Figure 1 and Figure 2 As shown, in the embodiment of the present utility model, the valve further includes an isolating member 60 , and the isolating member 60 is used to be installed on the inner wall of the through hole, and the first sealing portion and the second sealing portion are both in contact with the isolating member 60 .

[0058] In this embodiment, the isolating member 60 further enhances the sealing performance and structural stability of the valve assembly. The isolating member 60 is used to be installed on the inner wall of the through hole in the wheel hub 20, and it abuts against the first sealing portion and the second sealing portion of the sealing member 50 to form an additional sealing layer. At the same time, it can reduce the friction between the sealing member 50 and the inner wall of the through hole, thereby protecting the inner wall of the through hole from wear and extending the service life of the wheel hub.

[0059] Combination Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the valve further includes a gasket 70 and a locking piece 71. The gasket 70 is sleeved on the valve body and located outside the wheel hub. The locking piece 71 is threadedly connected to the valve body 10 and presses the gasket 70 against the wheel hub.

[0060] In this embodiment, the gasket 70 and the locking member 71 provide additional fixing and sealing support for the valve body 10. The gasket 70 is configured to be sleeved on the valve body 10 and located outside the wheel hub 20, thereby enhancing the sealing between the valve and the wheel hub.

[0061] The function of the locking piece 71 is to be connected to the valve body 10 through a threaded connection to ensure the stability of the valve body 10 on the wheel hub 20. The locking piece 71 can apply appropriate pressure to the gasket 70 through the threaded connection mechanism, so that it is tightly pressed against the wheel hub 20, and the time required for replacing parts is reduced, thereby improving the replacement efficiency.
