[0053] The tire pressure sensor module and the vehicle having the same according to the embodiment of the utility model are described in detail below with reference to the accompanying drawings.

[0054] Reference Figures 1 to 6 As shown, the tire pressure sensor 10 module provided according to the embodiment of the utility model includes a tire pressure sensor 10 , a valve stem 20 and a locking screw 30 .

[0055] Specifically, the tire pressure sensor 10 is used to monitor tire pressure. The tire pressure sensor 10 includes a housing, and a connection seat 101 is provided on the housing. The connection seat 101 has a swing hole H101 that penetrates the connection seat 101. Exemplarily, the connection seat 101 is formed as a structure protruding from the surface of the housing, and such a protruding structure is convenient for assembly and connection with the valve 20.

[0056] It should be noted that the tire pressure sensor 10 usually also includes a tire pressure monitoring module arranged in the shell. The shell is provided with air holes for gas to flow into the shell so as to detect tire pressure through the tire pressure monitoring module. The detected tire pressure data is sent wirelessly to the data acquisition device on the vehicle to realize tire pressure monitoring.

[0057] The valve stem 20 has a first end D201 and a second end D202, wherein the first end D201 is used to connect to the tire valve, and the second end D202 is inserted into the swing hole H101 and can swing in the swing hole H101, so that the valve stem 20 can be rotated and adjusted relative to the tire pressure sensor 10 within the angle range defined by the swing hole H101.

[0058] The valve 20 is usually a rod-shaped member, and the first end D201 of the valve 20 is connected to the tire valve by means of threading, clamping, etc. After the valve 20 is connected to the tire valve, the tire pressure sensor 10 assembly can be installed in the tire. The second end D202 of the valve 20 is inserted into the swing hole H101 of the connecting seat 101 and can swing, so as to realize the movable connection between the tire pressure sensor 10 and the valve 20. Before the first end D201 of the valve 20 is not connected to the tire valve, the valve 20 and the tire pressure sensor 10 can rotate relative to each other, and after the first end D201 of the valve 20 is connected to the tire valve, the valve 20 is fixed to the tire, and the tire pressure sensor 10 can rotate relative to the valve 20, thereby adjusting the angle of the tire pressure sensor 10 so that the tire pressure sensor 10 can be close to the wheel hub of the tire.

[0059] The locking screw 30 is arranged on the connection seat 101 and is threadedly connected to the second end D202, so as to selectively lock and fix the sensor to the valve 20. On the one hand, the locking screw 30 is threadedly connected to the second end D202 of the valve 20 on the connection seat 101, so that the second end D202 of the valve 20 will not be separated from the connection seat 101, and the assembly relationship between the two is maintained. On the other hand, when the angle of the tire pressure sensor 10 needs to be adjusted, the locking screw 30 can be loosened, and after the tire pressure sensor 10 is rotated to a suitable angle, the locking screw 30 can be tightened again, so that the tire pressure sensor 10 is locked and fixed to the connection seat 101, and then stably maintained at the angle position.

[0060] According to the tire pressure sensor 10 module provided by the embodiment of the utility model, the second end D202 of the valve stem 20 is inserted into the swing hole H101 on the connecting seat 101 and swings, so that the valve stem 20 can be rotatably adjusted relative to the tire pressure sensor 10 within the angle range defined by the swing hole H101, and the locking screw 30 can selectively lock and fix the sensor to the valve stem 20. In this way, in the installation of different tires, after the first end D201 of the valve stem 20 is connected to the tire valve, the tire pressure sensor 10 can be rotated and adjusted so that the tire pressure sensor 10 is close to the wheel hub, and then the tire pressure sensor 10 can be locked and fixed by the locking screw 30. Therefore, the adaptability of the tire pressure sensor 10 module to different tires can be improved, and the locking screw 30 can be reliably locked with low cost.

[0061] Reference Figures 3 to 5 As shown, in one embodiment of the utility model, the swing hole H101 includes a first limiting wall S01 and a second limiting wall S02, the first limiting wall S01 and the second limiting wall S02 are arranged relatively to each other, and a predetermined angle is defined between the first limiting wall S01 and the second limiting wall S02, and the predetermined angle is used to limit the angle range of rotation adjustment of the valve mouth 20 relative to the tire pressure sensor 10.

[0062] That is to say, a generally trapezoidal space is defined between the first limiting wall S01 and the second limiting wall S02, and the first limiting wall S01 and the second limiting wall S02 are respectively located on the two waists of the trapezoid. When the second end D202 of the valve stem 20 is inserted into the swing hole H101 and connected to the locking screw 30, the second end D202 of the valve stem 20 can swing relative to the tire pressure sensor 10 in the space defined by the first limiting wall S01 and the second limiting wall S02. In this way, the first limiting wall S01 and the second limiting wall S02 can be used to limit the angular range of rotation of the valve stem 20 relative to the tire pressure sensor 10.

[0063] In this embodiment, the first limiting wall S01 and the second limiting wall S02 of the swing hole H101 are designed to ensure that the swing amplitude of the valve stem 20 or the tire pressure sensor 10 is controlled within a predetermined angle range, thereby ensuring the reliability of the angle adjustment of the tire pressure sensor 10.

[0064] Reference Figure 5 As shown, in one embodiment of the utility model, the swing hole H101 also includes two plane walls S03, the two plane walls S03 are arranged opposite to each other and are parallel, one of the two plane walls S03 is connected between one side of the first limiting wall S01 and the second limiting wall S02, and the other of the two plane walls S03 is connected between the other side of the first limiting wall S01 and the second limiting wall S02.

[0065] The distance between the two plane walls S03 matches the thickness dimension of the second end D202 , and the thickness dimension of the second end D202 is a dimension perpendicular to the axial direction of the valve 20 .

[0066] In this embodiment, the two plane walls S03 and the first limiting wall S01 and the second limiting wall S02 jointly define a swing hole H101. The two plane walls S03 are arranged in parallel, and the distance between the two is adapted to the thickness dimension of the second end D202 of the valve 20. In this way, when the second end D202 of the valve 20 is inserted into the swing hole H101, the two sides of the second end D202 in the thickness direction are respectively close to the two plane walls S03. The two plane walls S03 can limit the freedom of the second end D202 in the thickness direction, thereby ensuring that the second end D202 of the valve 20 can only swing between the first limiting wall S01 and the second limiting wall S02, thereby improving the reliability and stability of the relative rotation between the valve 20 and the tire pressure sensor 10.

[0067] Preferably, the second end D202 has two side planes S06 facing each other, and the two side planes S06 correspond to the two plane walls S03 one by one, and each side plane S06 fits the corresponding plane wall S03. That is, the two side planes S06 of the second end D202 fit the two plane walls S03 in the swing hole H101 respectively, so that the contact area is increased by using the plane contact between the side planes S06 and the plane wall S03, so that the relative rotation between the valve 20 and the tire pressure sensor 10 is more stable. In addition, this structural design also makes the assembly relationship between the valve 20 and the connecting seat 101 more stable. In the application scenario of automobile driving, the failure rate is low, the service life is long, and the performance is more stable and reliable.

[0068] It should be noted that, in other embodiments of the present invention, the limitation of the angular range of relative rotation between the valve stem 20 and the tire pressure sensor 10 may also be achieved by using other limiting structures, as long as the limitation of the angular range can be achieved.

[0069] As for the first limiting wall S01 and the second limiting wall S02, they can be planes or arc surfaces matched with the outer surface of the second end D202.

[0070] Reference Figure 3 to Figure 4 As shown, in one embodiment of the present invention, the second end D202 is provided with an axially extending threaded hole, the connecting seat 101 is provided with a through hole H102 intersecting the swing hole H101, and the locking screw 30 passes through the through hole H102 and then engages with the threaded hole. When the second end D202 rotates in the swing hole H101, the locking screw 30 swings with the second end D202 in the through hole H102.

[0071] That is to say, in this embodiment, the locking screw 30 is inserted into the through hole H102 and is threadedly connected to the second end D202 along the axial direction of the second end D202. The locking or loosening direction of the locking screw 30 is achieved by rotating around the axis direction of the second end D202. The axis of the swing of the second end D202 of the valve 20 is perpendicular to the axis direction of the second end D202. In other words, the rotation axis of the locking screw 30 is perpendicular to the rotation axis of the second end D202. This perpendicular relationship will not affect the tightness of the locking screw 30 during the process of the tire pressure sensor 10 rotating to adjust the angle, that is, during the relative rotation of the tire pressure sensor 10 and the second end D202. Therefore, when it is used in a car, the tire pressure sensor 10 may vibrate due to various factors such as bumpy driving of the car, but this vibration will not affect the tightness of the locking screw 30, thereby ensuring that the tire pressure sensor 10 component can maintain long-term stability and reliability in the application of the car, and significantly reducing the adverse effects of bumps and vibrations on the tire pressure sensor 10 component.

[0072] It is understandable that in other embodiments of the present invention, in order to open a threaded hole or a pivot hole along the thickness direction (i.e., radial direction) of the second end D202, the through hole H102 is opened on one side of the connecting seat 101, and the locking screw 30 is passed through the through hole H102 on the connecting seat 101 and then matched with the threaded hole or the pivot hole, so that the second end D202 can also be rotated and adjusted in the swing hole H101. However, at this time, the rotation axis of the second end D202 coincides with or is parallel to the rotation axis of the locking screw 30. In this case, during the relative rotation of the tire pressure sensor 10 and the second end D202, the tightness of the locking screw 30 will be affected, thereby reducing reliability.

[0073] Preferably, the through hole H102 is a fan-shaped hole, and the fan-shaped hole has two limiting side surfaces, and a fan-shaped interval is defined between the two limiting side surfaces, and the locking screw 30 can swing within the fan-shaped interval. The function of the fan-shaped hole is to provide a movable space for the locking screw 30 so that it can swing along with the second end D202. When the second end D202 swings in the swing hole H101 relative to the tire pressure sensor 10, the locking screw 30 swings along with it in the fan-shaped hole. The fan-shaped hole design is conducive to the following swing of the locking screw 30, and the structure is compact and adapted to the swing range of the locking screw 30.

[0074] It is understandable that the through hole H102 may also be designed to be other shapes, such as a rectangular hole, a cylindrical hole, or a conical hole, as long as the size of the through hole H102 allows the locking screw 30 to swing along with the second end D202.

[0075] Reference Figures 3 to 5 As shown, in one embodiment of the utility model, the swing hole H101 has an open end away from the through hole H102, and the swing hole H101 has a ball socket surface S05 opposite to the open end, the through hole H102 passes through the ball socket surface S05, and the end surface of the second end D202 is a spherical surface S07, and the spherical surface S07 is rotatably matched with the ball socket surface S05.

[0076] During the assembly process between the valve stem 20 and the tire pressure sensor 10, the second end D202 of the valve stem is inserted into the swing hole H101 from the open end until the spherical surface S07 of the second end D202 is in contact with the ball socket surface S05 in the swing hole H101, and then the locking screw 30 is inserted through the through hole H102 and threadedly connected to the threaded hole of the second end D202. After tightening the locking screw 30, the head 301 of the locking screw 30 is pressed against the connecting seat 101, and the ball socket surface S05 can maintain a close contact with the spherical surface S07 of the second end D202.

[0077] During the rotation of the second end D202 relative to the tire pressure sensor 10, friction occurs between the spherical surface S07 and the socket surface S05. Since the spherical surface S07 is adapted to the socket surface S05, they have a larger contact area, thereby ensuring that the relative rotation between the second end D202 and the tire pressure sensor 10 is smoother and more stable. In addition, after the locking screw 30 is tightened, the relative fixed state between the tire pressure sensor 10 and the valve stem 20 is also more stable and reliable.

[0078] Reference Figures 2 to 4 As shown, in one embodiment of the present utility model, a gasket 31 is sleeved on the locking screw 30 , and the gasket 31 is pressed against the connecting seat 101 by the head 301 of the locking screw 30 .

[0079] In this embodiment, a gasket 31 is sleeved on the locking screw, and the gasket 31 isolates the head 301 of the locking screw 30 from the surface of the connecting seat 101, so that during the swinging process, the friction between the head 301 of the locking screw 30 and the connecting seat 101 can be reduced, thereby improving the service life. In addition, there is a larger contact area between the gasket 31 and the connecting seat 101, so that the head 301 of the locking screw 30 is pressed against the connecting seat 101 through the gasket 31, ensuring a more reliable locking effect.

[0080] Reference Figures 3 to 6As shown, in one embodiment of the present invention, the connection seat 101 has an arc surface S08, the through hole H102 is opened on the arc surface S08, and the gasket 31 is formed into an arc shape that matches the arc surface S08 and fits the arc surface S08. Since the rotation path of the second end D202 is an arc, the surface of the connection seat 101 that contacts the gasket 31 is configured as the arc surface S08, and at the same time, the gasket 31 is configured as an arc shape that matches the arc surface S08. In this way, the arc design that matches the rotation path makes the locking screw 30 follow more smoothly and reliably, and the assembly relationship between the locking screw 30 and the connection seat 101 is more stable.
