Description

Technical Field

[0001] This utility model relates to the field of automotive tire valve technology, specifically to an adjustable-angle TPMS valve. Background Technology

[0002] To enable real-time monitoring, the system is equipped with a TPMS (Tire Pressure Monitoring System) on each tire. This system monitors the pressure and temperature inside the tire and transmits the data to a TPMS receiver inside the vehicle. To ensure a secure installation of the TPMS transmitter and prevent it from falling off under various harsh driving conditions, the TPMS transmitter is typically mounted on the tire rim and fixed to the valve stem.

[0003] Currently, most TPMS valve stems use screws to connect the transmitter and valve stem rod. After connection, the valve stem angle is fixed. Generally, one valve stem is shared by one or a few wheel hub models. This results in a large number of TPMS valve stem models, making it inconvenient for vehicle manufacturers to assemble and use them.

[0004] For example, in the existing patent technology with patent publication number CN116691242A, entitled "A Universal Self-Adjusting Angle Valve for One-Time Installation of TPMS and Assembly Method," it is disclosed that "This invention discloses a universal self-adjusting angle valve for one-time installation of TPMS and assembly method, wherein the valve includes a transmitter, valve stem, rubber gasket, washer, nut, and rim piece; a washer is fitted at the hinge; a wedge-shaped structure is formed at the connection between the bottom of the valve stem and the washer; the rubber gasket is fitted on the valve stem, and the lower part of the rubber gasket is connected to the top of the washer; the rim piece is located above the rubber gasket and connected to the valve stem; the nut is installed on the rim piece above the valve stem." In the above technology, the transmitter and valve stem are fixedly connected, which results in many TPMS valve models, making assembly and use inconvenient for vehicle manufacturers. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to solve the problem of poor universality of valve stems.

The valve stem assembly includes a valve stem and a chassis connected to the tail of the valve stem. The tail of the chassis is arc-shaped, and the transmitter also has a corresponding arc-shaped part at the contact position with the tail of the chassis.

[0008] The nozzle is provided with a tail connector at the tail end. The tail connector passes through the chassis and connects to the mounting groove. The ground where the tail connector contacts the mounting groove has an arc-shaped part.

[0009] This application sets the surfaces of the transmitter, nozzle rod, and chassis that contact each other as arc-shaped surfaces. At the same time, the rear of the chassis and the rear of the nozzle rod are also set as arc-shaped surfaces. By utilizing the principle of arc surfaces, the angle of the transmitter can be adjusted and the position of the transmitter can be adjusted, realizing the function of adjustable angle in one installation and improving the versatility of the wheel hub.

[0010] As a further embodiment of this utility model: arc-shaped limiting grooves are provided on both sides of the tail section where the chassis contacts the transmitter, and the arc-shaped part of the transmitter can be locked in the arc-shaped limiting grooves on both sides of the chassis.

[0011] As a further embodiment of this utility model: a mounting hole for connecting the nozzle rod is provided in the middle of the chassis, wherein the mounting hole corresponds to the position of the mounting groove.

[0012] As a further embodiment of this utility model, both the mounting hole and the mounting groove are waist-shaped grooves.

[0016] This application sets the surfaces of the transmitter, nozzle rod, and chassis that contact each other as arc-shaped surfaces. Simultaneously, arc-shaped surfaces are also set at the tail of the chassis and the tail of the nozzle rod. Utilizing the principle of arc surfaces, the transmitter's angle can be adjusted. During installation, the tightening force of the nuts applies force from the nozzle rod and chassis to the transmitter, firmly locking the transmitter groove and the arc-shaped surface at the tail of the nozzle rod. At this point, the transmitter's position is fixed in the desired location. The entire installation process only requires tightening the nuts; the transmitter's position can be adjusted, achieving a one-time installation angle adjustment function and improving hub versatility.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Reference Figure 1 An adjustable angle TPMS valve includes a transmitter 1, a chassis 2, a rubber pad 3, and a valve stem 4. The tail of the valve stem 4 passes through the chassis 2 and is connected to the transmitter 1. After being adjusted to the corresponding angle, the rubber pad 3 is inserted from the head of the valve stem 4 and abuts against the chassis 2. Finally, the valve stem 4 is fixed by bolts.

[0029] Reference Figure 2 , Figure 4 and Figure 5 An arc-shaped part is provided at the position where the transmitter 1 connects to the nozzle rod 4, and the arc direction of the arc part is towards the chassis 2. A mounting groove 101 is also provided on the arc part, and the mounting groove 101 adopts an waist-shaped hole structure. It should be noted that the bottom horizontal plane of the arc part is higher than the bottom horizontal plane of the transmitter 1, and there is a step between the two that can contact the chassis 2.

[0030] Reference Figure 2 and Figure 3The end of the chassis 2 closest to the transmitter 1 is configured with an arc-shaped surface corresponding to the arc-shaped part of the transmitter 1. The arc-shaped surface of the chassis 2 can contact the arc-shaped part of the transmitter 1. The chassis 2 has a mounting hole 201 inside that connects to the nozzle rod 4. The mounting hole 201 and the mounting groove 101 both adopt an oblong hole structure. Cuts are set on both sides of the arc-shaped surface of the chassis 2 to form an arc-shaped limiting groove 202. It should be noted that the arc-shaped part and the transmitter 1 form a stepped section that fits precisely at the position of the arc-shaped limiting groove 202. When the nozzle rod 4 adjusts its angle, it will drive the chassis 2 to adjust its angle along the arc-shaped part. At this time, the stepped section can also rotate and adjust at the position of the arc-shaped limiting groove 202.

[0031] Furthermore, the mounting hole 201 is located directly below the mounting groove 101, and the two are positioned correspondingly. For ease of understanding and description, the vertical direction here is referred to as... Figure 1 and Figure 2 For example, the other directions can be deduced from this. It should be understood that this direction setting is only for the convenience of description and understanding, and should not be construed as a limitation on this application.

[0032] Reference Figure 2 The nozzle rod 4 is provided with a tail connector 401 at the end facing the transmitter 1. The tail connector 401 is rectangular in shape. The side of the tail connector 401 facing away from the transmitter 1 is provided with an arc-shaped part 402. The tail connector 401 passes through the mounting hole 201 in the chassis 2 and is inserted into the upper part of the mounting groove 101. The arc-shaped part 402 can contact the arc-shaped surface above the mounting groove 101.

[0033] Furthermore, symmetrical cuts are provided on the end of the nozzle rod 4 facing the transmitter 1 to form a positioning part 403. This creates an oblong columnar structure at the positioning part of the nozzle rod that corresponds to the mounting hole 201. The positioning part 403 can extend into the oblong mounting hole 201, thus completing the installation. Figure 1 The state shown.

[0034] The specific operating principle of this application is as follows:

[0035] During product installation, first fix the chassis 2 structure to the nozzle rod 4 through the mounting hole 201, that is, pass the tail connector 401 through the mounting hole 201, and then the positioning part 403 is inserted into the mounting hole 201. Then, pass the nozzle rod 4 through the mounting groove 101 of the transmitter and rotate it 90 degrees so that the arc-shaped part 402 of the nozzle rod connector and the arc surface of the chassis match the inner and outer arc surfaces of the transmitter. Then, install the rubber gasket 3 into the chassis. When installing the TPMS valve on the wheel hub, first insert the valve rod 4 into the rim hole, adjust the transmitter 1 to the required position, and then tighten the nut on the nozzle rod 4.
