[0002] With the rapid development of the automotive industry and the increasing emphasis on driving safety, tire pressure monitoring systems have become an indispensable part of modern automobiles. As the core component of the tire pressure monitoring system, the stability, sealing, and ease of installation of the tire pressure sensor directly affect the system's monitoring accuracy and lifespan, thus impacting driving safety.

[0003] In existing technologies, the sensor and nozzle are often integrated into one design. When a single component fails, it cannot be replaced separately; the sensor and nozzle must be replaced together. This undoubtedly increases maintenance costs significantly, causes unnecessary waste of resources, and imposes an additional economic burden on users. Therefore, improvements are needed.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example: Figures 1-4 As shown, this utility model provides a technical solution: an installation structure for a car tire pressure sensor, including a tire pressure sensor body 1 and an air valve 2.

An installation plate 11 is fixedly installed on the inner surface of the installation groove 10. A spring 12 is fixedly installed on the side of the installation plate 11 away from the installation groove 10. A limit block 13 is fixedly installed on the end of the spring 12 away from the installation plate 11. A limit hole 14 is opened through the top of the rod 9. The fixing plate 5... A side plate 15 is fixedly installed on one side of the device. A sliding column 16 is slidably connected inside the side plate 15. A retaining ring 17 is fixedly installed on the outer wall of the sliding column 16. A spring 18 is sleeved on the outer wall of the sliding column 16. A handle 19 is fixedly installed on the top outer wall of the sliding column 16. The round hole 6 and the positioning groove 7 are interconnected. The air nozzle 2 is slidably connected to the round hole 6. The limiting block 13 is slidably connected to the mounting groove 10. The positioning block 4 is slidably connected to the positioning groove 7. One end of the spring 18 is fixedly connected to the retaining ring 17. The other end of the spring 18 is fixedly connected to the side plate 15. The sliding column 16 is slidably connected to the limiting hole 14. A rubber sealing gasket 20 is fixedly installed on the side of the fixing ring 3 away from the fixing plate 5. A gasket 21 is slidably connected to the outer wall of the air nozzle 2. A threaded sleeve 22 is threadedly connected to the outer wall of the air nozzle 2. A protective cap 23 is threadedly connected to the outer wall of the air nozzle 2.

[0021] In this embodiment, the tire pressure sensor body 1 and the valve 2 are detachably connected through the cooperation of components such as positioning block 4, fixing plate 5, round hole 6, positioning groove 7, slot 8, insertion rod 9, mounting groove 10, mounting plate 11, spring 12, limiting block 13, limiting hole 14, side plate 15, sliding column 16, retaining ring 17, spring 18, and pull handle 19. When one component is damaged, it can be disassembled and replaced individually without replacing the whole unit, which greatly reduces maintenance costs, reduces unnecessary resource consumption, and alleviates the economic burden on users. At the same time, the installation of this structure can be completed by the precise positioning of positioning block 4 and positioning groove 7, and the simple operation of components such as insertion rod 9, limiting block 13, and sliding column 16 without complicated tools. When disassembling, only pulling handle 19 and pressing limiting block 13 are needed to pull out insertion rod 9, realizing quick separation of components, greatly simplifying the installation and maintenance process, and saving labor costs.

[0022] The working principle of this embodiment is as follows: During installation, the air nozzle 2 is first passed through the round hole 6 on the fixing plate 5, and at the same time, the positioning block 4 on the outer wall of the air nozzle 2 slides into the positioning groove 7 of the fixing plate 5. The cooperation between the positioning block 4 and the positioning groove 7 plays a role in precise positioning and avoids misalignment during installation. When the positioning block 4 is fully inserted into the positioning groove 7, the fixing plate 5 and the slot 8 on the positioning block 4 are aligned. After alignment, the insertion rod 9 is aligned and inserted into the slot 8. After being inserted a certain distance, the limiting block 13 is pressed. At this time, the limiting block 13 compresses the spring 12 in the mounting groove 10 and retracts into the mounting groove 10 so that the insertion rod 9 can continue to be inserted into the slot 8 smoothly. After the insertion rod 9 is inserted a certain distance further, the handle 19 is pulled upward, which drives the sliding column 16 to move upward inside the side plate 15. The sliding column 16 moves upward. During the process, the retaining ring 17 will move together and compress the second spring 18, so that the bottom end of the sliding column 16 is away from the top of the insertion rod 9, making room for the further insertion of the insertion rod 9, so that the insertion rod 9 can be fully inserted into the slot 8. When the insertion rod 9 is fully inserted, the first spring 12 returns to its natural state, pushing the limiting block 13 out of the mounting groove 10. The limiting block 13 abuts against the outer side of the fixing plate 5, initially limiting the insertion rod 9 to prevent the insertion rod 9 from easily sliding out of the slot 8. Then, the pull handle 19 is released, the second spring 18 returns to its elasticity, and the sliding column 16 moves downward, its bottom end is inserted into the limiting hole 14 at the top of the insertion rod 9, further fixing the insertion rod 9 and ensuring that the insertion rod 9 is firmly in the slot 8, thereby firmly connecting the fixing plate 5 and the positioning block 4, realizing the installation and fixation of the tire pressure sensor body 1 and the valve 2. The retaining ring 3 on the outer wall of the valve stem 2 and the rubber sealing gasket 20 on the retaining ring 3 abut against the wheel hub after installation, which can effectively enhance the sealing of the connection between the valve stem 2 and the wheel hub and prevent moisture, dust and other substances from entering. The sliding gasket 21 and the threaded sleeve 22 on the outer wall of the valve stem 2 can further strengthen the connection between the valve stem 2 and the wheel hub during installation and improve the stability of the overall structure. The protective cap 23 can protect the end of the valve stem 2 and prevent impurities from entering the valve stem 2. When it is necessary to replace the tire pressure sensor body 1 or the valve stem 2, simply pull the handle 19 to move the sliding column 16 upward and disengage it from the limiting hole 14 on the insertion rod 9, release the limitation on the insertion rod 9, and then press the limiting block 13 to compress the spring 12 and retract it into the mounting groove 10. The insertion rod 9 can then be pulled out from the slot 8. At this time, the connection between the fixing plate 5 and the positioning block 4 is released, and the tire pressure sensor body 1 and the valve stem 2 can be removed and replaced separately, realizing the independent replacement of a single component and reducing maintenance costs.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
