Description

Technical Field

[0001] The utility model relates to the technical field of TPMS valve nozzles, in particular to a one-time installation self-fixing angle-adjusting TPMS valve nozzle. Background Art

[0002] The PMS system is a system that monitors tire pressure in real time by using a tire pressure sensor unit and a tire pressure monitoring unit that use wireless radio frequency communication. In order to achieve real-time monitoring, the system installs a TPMS transmitter on each tire, which can monitor the pressure and temperature inside the tire and send it to the TPMS receiver in the car. In order to achieve a fixed installation of the TPMS transmitter and prevent it from falling off under various harsh vehicle conditions, the TPMS transmitter is generally installed on the rim of the tire and fixed together with the valve stem.

[0003] However, most of the existing TPMS valves require secondary installation. The first time, the valve stem, rubber pad, and gasket are assembled. The second time, the transmitter needs to be assembled and adjusted according to the rim angle and locked with screws. The secondary installation is prone to errors. Secondly, the large torque between the valve stem and the gasket will directly squeeze the transmitter housing and thus damage the transmitter. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to solve the problem of inconvenience in assembling the current TPMS valve and transmitter.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A one-time installation self-fixing angle-adjusting TPMS valve comprises a valve rod, a lower flat square and an arc-shaped gasket, wherein one end of the valve rod is connected to the lower flat square, wherein an outer side of the valve rod and an end close to the lower flat square is provided with an expansion rivet outer ring, the expansion rivet outer ring is sleeved with the arc-shaped gasket, and an expansion rivet inner ring corresponding to the expansion rivet outer ring is also provided inside the arc-shaped gasket.

[0007] The TPMS valve of the present application can be installed once, and there is no need to adjust the transmitter angle for the second time or connect the transmitter with the help of additional screws; the valve and the transmitter are connected by the lower flat square of the nozzle rod, which is locked after the transmitter is compressed. The nozzle rod and the gasket use the principle of wedge expansion sleeve. The gasket holds the nozzle rod tightly when the nozzle rod is axially displaced. The greater the axial force on the gasket, the greater the radial force between the nozzle rod and the gasket. The tighter the nozzle rod and the gasket are, the axial displacement of the gasket before the nozzle rod is clamped is achieved. The lower flat square on the nozzle rod is used to make the transmitter ball arc connection subject to upper and lower axial forces, and the transmitter is hung up. The transmitter ball arc and the spherical surface of the gasket automatically adjust the spoke angle before being subjected to force, fix the transmitter, and lock the TPMS valve.

[0008] As a further solution of the utility model: a rubber pad is sleeved at the connection position between the arc-shaped gasket and the nozzle rod for sealing.

[0009] As a further solution of the utility model: the arc-shaped gasket and the rubber gasket are both radially fixed to the nozzle rod.

[0010] As a further solution of the utility model: the expansion riveting outer ring is in a conical structure, and the outermost circle diameter of the expansion riveting outer ring is larger than the inner diameter of the rubber pad.

[0011] As a further solution of the utility model: the outermost circle diameter of the expansion rivet outer ring is larger than the outermost circle diameter of the nozzle rod.

[0012] As a further solution of the utility model: the outer diameter of the expansion riveted outer ring gradually increases in the direction of the lower flat square.

[0013] As a further solution of the utility model: the inner expansion ring is in a cone-shaped structure, and the inner expansion ring is fitted with the outer expansion ring.

[0014] As a further solution of the utility model: a nut is also installed on the outer side of the nozzle rod.

[0015] As a further solution of the utility model: the lower flat square is a "T"-shaped structure, which is installed in the TPMS transmitter housing.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The TPMS valve of the present application can be installed once, and there is no need to adjust the angle of the transmitter twice or connect the transmitter with additional screws; the valve and the transmitter are connected by the lower flat square of the self-use nozzle rod, which is locked after the transmitter is compressed. The nozzle rod and the gasket use the principle of wedge expansion sleeve. The gasket holds the nozzle rod tightly when the nozzle rod is axially displaced. The greater the axial force on the gasket, the greater the radial force between the nozzle rod and the gasket, and the tighter the nozzle rod and the gasket, the lower flat square is used to make the upper and lower axial forces on the connection of the transmitter ball arc, and the transmitter is hung up. The transmitter ball arc and the spherical surface of the gasket automatically adjust the spoke angle before the force is applied, fix the transmitter, and lock the TPMS valve;

[0018] 2. The present application provides an expansion rivet outer ring on the outside of the nozzle rod, and provides an expansion rivet inner ring corresponding to the expansion rivet outer ring inside the arc-shaped gasket, wherein the expansion rivet inner ring and the expansion rivet outer ring are fitted to form an expansion mortise design, which solves the problem of large torque directly squeezing the transmitter housing and damaging the transmitter. At the same time, the expansion mortise design also solves the problem of the gasket and the nozzle rod being directly clamped by force, and the nozzle rod spinning after the rim is installed;

[0019] 3. The contact position between the nozzle rod and the gasket of the present application is a wedge-shaped structure as a whole. This design makes the gasket more tightly fixed to the nozzle rod as the force on the gasket increases, thus preventing the transmitter housing from being damaged by a large axial force, and the design structure is simple;

[0020] 4. The spherical surface of the gasket of the present application and the spherical surface of the transmitter are highly applicable and compatible with different spoke angles, and do not require pre-adjustment at the tire factory; the T-hook of the mouth rod is used in conjunction with the gasket to fix the transmitter, without the need to use screws to fix the transmitter; locking the transmitter does not require auxiliary screws to connect, and the design structure of the present application is simple, reasonable, and highly versatile.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A one-time installation self-fixing angle adjustment TPMS valve, comprising a valve assembly 1 with a TPMS transmitter 2 installed at one end, the valve assembly 1 comprising an arc-shaped gasket 11, a lower flat square 12, a rivet outer ring 13, a rubber pad 14, a nozzle rod 15 and a nut 16, the arc-shaped gasket 11 and the rubber pad 14 are radially fixed to the nozzle rod 15, it should be noted that the arc-shaped gasket 11 is a metal gasket; the lower flat square 12 is installed at the end of the nozzle rod 15 facing the TPMS transmitter 2, and the rivet outer ring 13 is installed on the outside of the nozzle rod 15 and has an installation gap with the lower flat square 12, the arc-shaped gasket 11 is installed on the outside of the rivet outer ring 13 and the nozzle rod 15, and a rubber pad 14 is further provided between the arc-shaped gasket 11 and the nozzle rod 15 for fastening, and the rivet outer ring 13 is fitted with the arc-shaped gasket 11; a nut 16 is further installed on the outside of the nozzle rod 15 and on the rear side facing away from the TPMS transmitter 2.

[0028] Reference Figure 2 , Figure 3 and Figure 4 The arc-shaped gasket 11 is independently arranged, and has an arc-shaped and bowl-shaped structure, and its interior includes a rectangular mounting groove and a conical groove formed by a rivet inner ring 111, that is, the inner hole of the metal gasket is designed with an internal inclination, and the rectangular mounting groove is used to install the rubber pad 14; and the direction of the inclination is that the outer diameter of the rivet inner ring 11 toward the side of the rectangular mounting groove is getting smaller and smaller, and the corresponding outer diameter of the rubber pad 14 is larger than the maximum outer diameter of the rivet inner ring 11, so that the rubber pad 14 can play a role of limiting sealing for the rivet inner ring 11, and the spherical surface of the arc-shaped gasket 11 can automatically adjust the spoke angle before being subjected to force, fix the transmitter, and lock the TPMS valve.

[0029] Reference Figure 2 , Figure 3 and Figure 4 The lower flat square 12 is arranged at one end of the nozzle rod facing the TPMS transmitter 2. The lower flat square 12 is in a "T"-shaped structure and is installed in the TPMS transmitter housing. The T-shaped lower flat square 12 on the nozzle rod can be hung on the TPMS transmitter 2 during installation.

[0030] Reference Figure 2 , Figure 3 and Figure 4 The rivet outer ring 13 is arranged on the outside of the nozzle rod 15 and close to one end of the lower flat square 12. The rivet outer ring 13 is sleeved with the arc-shaped gasket 11, and the rivet outer ring 13 corresponds to the rivet inner ring 111, and the two fit together. Therefore, the rivet outer ring 13 is set with an outer inclination corresponding to the rivet inner ring 111. The rivet outer ring 13 has a conical structure. The outermost circle diameter of the rivet outer ring 13 is smaller than the inner diameter of the rubber pad 14. The rubber pad 14 can play a role of limiting sealing between the arc-shaped gasket 11 and the rivet outer ring 13; the outermost circle diameter of the rivet outer ring 13 is larger than the outermost circle diameter of the nozzle rod 15; the outer diameter of the rivet outer ring 13 gradually increases toward the lower flat square 12.

[0031] It should be noted that the wedge-shaped structural design of the nozzle rod 15 and the arc-shaped gasket 11 in the present application specifically refers to the wedge-shaped design between the expansion rivet outer ring 13 and the expansion rivet inner ring 111 . The greater the force on the arc-shaped gasket, the tighter it is fixed to the nozzle rod 15 .

[0032] Reference Figure 1 A nut 16 adjusting piece is also designed outside the mouth rod 15. When the arc-shaped gasket 11 is displaced by force, the mouth rod can be more tightly held by the nut.

[0033] The specific working principle of this application is as follows:

[0034] The nut 16 locks the valve, and when the nozzle rod 15 is at a certain axial locking force, the arc-shaped gasket 11 is axially displaced, and the spherical surface of the gasket squeezes the transmitter housing. At the same time, the T-hook on the nozzle rod 15 hangs the transmitter, and the transmitter housing is subjected to the up and down axial force of the nozzle rod 15, pressing the TPMS transmitter 2. At this time, the axial force on the end face of the gasket 11 continues to increase, and the nozzle rod 15 and the expansion sleeve structure on the gasket are locked by force. The gasket and the nozzle rod 15 are connected as a whole to absorb the locking force of the nut 16 to prevent the transmitter housing from being damaged by a large axial force. The gasket 11 and the nozzle rod 15 absorb most of the preload force. The nozzle rod and the gasket of the TPMS valve are designed with a wedge structure. The transmitter is radially adjusted in the spherical surface of the gasket. It has strong versatility and is suitable for rims with different spoke angles, avoiding cumbersome assembly, reducing professional operations and improving efficiency.
