Description

Technical Field

[0001] This invention relates to the technical field of tire pressure sensors, and more particularly to a latching valve stem TPMS mounting structure and its assembly method. Background Technology

[0002] Tire pressure sensors are one of the key components of a car's tire pressure monitoring system. Installed on the wheels, they can monitor the tire pressure in real time and transmit the data to the vehicle's electronic control unit. If the tire pressure sensor malfunctions, the electronic control unit will not be able to receive the correct tire pressure data, causing the tire pressure monitoring system to malfunction.

[0003] Common tire pressure sensors are fixed to the valve stem by a threaded connection, which requires the use of a torque wrench to ensure that the tire pressure sensor does not become loose. However, the threaded connection between the tire pressure sensor and the valve stem requires tools for installation, and the threaded installation is relatively cumbersome, affecting the ease of installation of the tire pressure sensor. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a locking valve stem TPMS mounting structure and its assembly method to solve the problem of cumbersome installation of tire pressure sensor and valve stem.

[0005] Based on the technical problems existing in the background art, the present invention proposes a latching valve stem TPMS installation structure and its assembly method, including a valve core and a pressure sensor. The valve core has a tube body coaxially arranged at the outlet end. The outer side of the tube body is provided with an annular groove with a diameter smaller than the outer diameter of the tube body. The pressure sensor is provided with a ring buckle attached to the tube body. The annular groove is fitted with a buckle and the buckle is restricted between the annular groove and the valve core.

[0006] Preferably, the tube body has a locking hole extending into the tube body in a radial direction, and the side of the ring buckle has a hole extending in a radial direction. The ring buckle is fitted onto the tube body so that the hole is aligned with the locking hole and locked by inserting the buckle.

[0007] Preferably, the latch includes a connector and a locking member, one end of the locking member is connected to one side of the connector, one end of the connector is hinged to one end of the latch, and the connector can be flipped relative to the latch.

[0008] Preferably, the end of the locking member away from the connector is provided with a barb, and the locking member can be inserted into the lock hole so that the barb is locked inside the tube.

[0009] Preferably, the flip angle between the connector and the buckle is 90 degrees.

[0010] An assembly method for a latching valve stem TPMS mounting structure, comprising the following steps: first, connecting the pressure sensor's ring buckle to the tube body; then rotating the pressure sensor to align the locking hole with the bore; then inserting the locking member from the bore into the locking hole, and hooking the barb against the inner wall of the tube body; and finally flipping the buckle relative to the connecting member to lock and limit its position against the ring groove.

[0011] Compared with existing technologies, the latching valve stem TPMS mounting structure and its assembly method proposed in this invention achieve the following technical effects by adopting the above-mentioned technical solution:

[0012] This invention enables rapid fixing and disassembly of pressure sensors, facilitating sensor installation and fixation, thereby improving installation efficiency. Furthermore, this invention prevents accidental detachment of pressure sensors, enhancing the reliability of pressure sensor installation. Attached Figure Description

[0018] Example

[0019] Please refer to Figures 1-2 This invention proposes a latching valve stem TPMS mounting structure and its assembly method, including a valve core 1 and a pressure sensor 2. A tube body 3 is coaxially mounted on the outlet end of the valve core 1. An annular groove 31 with a diameter smaller than the outer diameter of the tube body 3 is provided on the outer side of the tube body 3. The pressure sensor 2 is provided with a ring buckle 21 attached to the tube body 3. A buckle 5 is installed in the annular groove 31 and restricts the ring buckle 21 between the annular groove 31 and the valve core 1. In this solution, the ring buckle 21 is located on the side of the pressure sensor 2, and the buckle 5 is a C-shaped buckle 5. When the ring buckle 21 is fitted onto the tube body 3, the buckle 5 is locked in place by the annular groove 31, which can restrict the ring buckle 21 between the end of the valve core 1 and the annular groove 31, and can prevent the ring buckle 21 from falling off the tube body 3, thus achieving a quick fixing effect.

[0020] In a specific embodiment, refer to Figure 1 , Figure 2 The tube body 3 has a locking hole 32 extending into the tube body 3 along the radial direction, and the ring buckle 21 has a hole 211 extending radially through the side. The ring buckle 21 is fitted onto the tube body 3 so that the hole 211 is aligned with the locking hole 32 and is locked by inserting the lock buckle 4. In this scheme, the entire sensor may rotate relative to the tube body 3. When the hole 211 and the locking hole 32 are aligned, the lock buckle 4 is used to lock the ring buckle 21 and the tube body 3. At this time, the ring buckle 21 will not rotate relative to the tube body 3 and can also limit the sliding of the ring buckle 21 relative to the tube body 3.

[0021] In a specific embodiment, refer to Figure 1 , Figure 2The latch 4 includes a connector 41 and a locking member 42. One end of the locking member 42 is connected to one side of the connector 41, and one end of the connector 41 is hinged to one end of the buckle 5. The connector 41 can be flipped relative to the buckle 5. In this solution, the latch 4 is separated into a connector 41 and a locking member 42. The locking member 42 is used to lock the hole 211 and the lock hole 32, which can restrict the ring buckle 21 from rotating relative to the tube body 3. However, the entire assembly may fall off as the tire rotates. Therefore, the locking member 42 is connected to the buckle 5 through the connector 41 to restrict the locking member 42 from falling off the hole 211 and the lock hole 32, thereby restricting the ring buckle 21. Furthermore, the length of the ring buckle 21 is equal to or slightly less than the minimum distance between the locking member 42 and the buckle 5. This can better restrict the space for the ring buckle 21 to slide on the tube body 3 and improve stability.

[0022] In a specific embodiment, refer to Figure 1 , Figure 2 The locking member 42 is provided with a barb 421 at the end away from the connector 41. When the locking member 42 is inserted into the lock hole 32, the barb 421 can be locked inside the tube body 3. The flip angle between the connector 41 and the buckle 5 is 90 degrees. In this solution, in order to further enhance the stability of the locking member 42 in the lock hole 32, when the locking member 42 is inserted into the lock hole 32, the barb 421 can be hooked with the inner wall of the tube body 3, which can further reduce the lock member 42 from falling out of the lock hole 32 and improve stability.

[0023] Please refer to Figures 1-2 An assembly method for a latching valve stem TPMS mounting structure, wherein the valve stem TPMS mounting structure is used for installation, including the following steps: first, the ring buckle 21 of the pressure sensor 2 is sleeved with the tube body 3; then, the pressure sensor 2 is rotated so that the locking hole 32 is aligned with the hole 211; then, the locking piece 42 is inserted from the hole 211 into the locking hole 32, and the barb 421 is hooked with the inner wall of the tube body 3; then, the buckle 5 is flipped relative to the connecting piece 41 and locked and limited by the ring groove 31.

[0024] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
