Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a tire with a tire pressure sensor valve structure having an inner and outer extended platform nozzle. Background Technology

[0002] As the only part of a car in contact with the ground, the stability of its internal pressure directly affects driving safety, fuel economy, and tire lifespan. Therefore, tire pressure monitoring systems have become an indispensable safety feature in modern vehicles. Among these, built-in tire pressure monitoring systems are widely used due to their high monitoring accuracy and ability to effectively avoid interference and damage from the external environment.

[0003] In existing technologies, built-in tire pressure monitoring sensors are typically installed on the inner wall of the wheel rim near the valve stem. A common mounting method involves using a rigid bracket or a mounting structure integrated into the sensor itself, and then screwing it directly onto the wheel rim. This design provides basic mounting functionality for specific wheel models.

[0004] However, there are many types of car wheels, and different brands, models, and even sizes of wheels have significant differences in the radius of curvature and structural shape of their inner walls. The aforementioned installation method using rigid, fixed brackets has poor structural adaptability. When the sensor is installed on a non-standard wheel, it is difficult for the bottom surface of its mounting platform to completely fit against the curved surface of the wheel's inner wall, inevitably creating an installation gap between them.

[0005] The existence of this installation gap fundamentally undermines the stability of the mounting. During vehicle operation, tires are subjected to continuous vibrations from road bumps and enormous centrifugal forces generated by high-speed rotation. This force, acting on a loosely mounted sensor, can cause minute displacement, wobbling, or even detachment. This instability not only severely interferes with sensor data acquisition, leading to inaccurate tire pressure monitoring readings or frequent false alarms, but also may accelerate the wear and tear on the sensor's electronic components due to long-term vibration, ultimately causing premature failure and creating serious safety hazards. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a tire with an inner and outer extended platform nozzle structure for fixing the tire pressure sensor valve. It aims to improve the problem in the prior art where the tire pressure monitoring sensor has poor adaptability of fixing structure, which makes it difficult to fit tightly with the inner wall of wheel hubs of different specifications, resulting in installation gaps, which causes unstable fixing and affects the accuracy of monitoring data.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a tire with an inner and outer extended platform nozzle fixed tire pressure sensor nozzle structure, including a wheel hub, a nozzle fixedly connected to the wheel hub, and a tire pressure monitor fixed to the inner side of the wheel hub; the tire pressure monitor is electrically connected to the inner end of the nozzle; The tire pressure monitoring device has an integrally extended fixed platform near the valve stem, and the bottom surface of the fixed platform is an inclined surface adapted to the curvature of the inner wall of the wheel hub. The fixed platform has an elongated slotted screw hole, the length of which is perpendicular to the axis of the air nozzle. The tire also includes a fixing assembly consisting of a fixing screw and a fixing plate. The fixing screw passes through the fixing plate and the screw hole in sequence and is threaded to the hub. The fixing plate is fitted onto the shank of the fixing screw and pressed against the top surface of the fixing platform.

[0008] Preferably, the tire pressure monitoring device also has an integrally formed anti-tire-repair fluid protrusion on its body.

[0009] Preferably, the anti-tire sealant protrusion is arranged around the outer side of the sensing core area of ​​the tire pressure monitor.

[0010] Preferably, the height of the anti-tire sealant boss is higher than the mounting plane of the core electronic component of the tire pressure monitoring device.

[0011] Preferably, the fixed platform has a structure that gradually thins towards the edges on both sides.

[0012] Preferably, the contact surface between the tire pressure monitor and the valve is an arc-shaped spherical structure.

[0013] Preferably, the contact surface of the fixing plate used to press the fixing platform is a plane.

[0014] Preferably, the bottom surface of the fixing platform is fixed to the inner wall of the wheel hub by means of adhesive or welding.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by setting a fixing platform with a sloping bottom surface and long slotted screw holes, and using fixing screws and fixing pressure plates for locking, the problem of poor fit and unstable fixing of the tire pressure monitor with different wheel hubs in the prior art is solved. It achieves the technical effects of strong installation adaptability, firm and reliable locking, effective resistance to driving bumps, and improved accuracy of monitoring data.

[0016] 2. In this utility model, by integrally molding an anti-tire sealant protrusion on the tire pressure monitor body, the problem of the core sensor components being easily damaged by the chemical corrosion of tire sealant in the prior art is solved, achieving the technical effects of effectively isolating and blocking tire sealant, protecting the core sensing components, significantly extending the product's service life and long-term working stability.

[0017] 3. This utility model solves the problem of easy transmission of vibration interference in the traditional rigid connection method by designing the contact surface between the tire pressure monitor and the valve as an arc spherical structure. It achieves the technical effects of reducing the interference of valve shaking on the monitoring data, making the monitor structure more compact, and optimizing the internal installation space of the wheel hub.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5This utility model provides a tire with an inner and outer extended platform nozzle structure for fixing the tire pressure sensor valve. It aims to solve the problem that the existing built-in tire pressure monitoring sensor is not tightly attached to the inner wall of the wheel hub, resulting in unstable fixation, and its core components are easily damaged by tire sealant.

[0022] The tire with an inner and outer extended platform nozzle fixed tire pressure sensor nozzle structure includes a hub 1, a nozzle 2, and a tire pressure monitoring device 3. The nozzle 2 is fixedly connected to the hub 1, and the tire pressure monitoring device 3 is fixed to the inner side of the hub 1 and electrically connected to the inner end of the nozzle 2. The hub 1 provides the mounting base for the entire device. The main structure of the nozzle 2 runs through the inner and outer sides of the hub 1 for tire inflation, and the tire pressure monitoring device 3 is used to monitor the pressure status inside the tire in real time.

[0023] To achieve a stable and adjustable installation, a fixed platform 4 is integrally extended from the tire pressure monitoring device 3 near the valve 2. The bottom surface of the fixed platform 4 is an inclined surface that adapts to the curvature of the inner wall of the wheel hub 1. This inclined surface structure increases the contact area between the fixed platform 4 and the inner wall of the wheel hub 1, thereby ensuring a tight fit. The fixed platform 4 has an elongated slotted screw hole 5. The length direction of the screw hole 5 is perpendicular to the axis of the valve 2. This layout allows the tire pressure monitoring device 3 to be finely adjusted in position along the tangent direction of the wheel hub 1 during installation.

[0024] The tire also includes a fixing assembly consisting of a fixing screw 6 and a fixing plate 7. During the fixing operation, the shank of the fixing screw 6 passes through the through hole of the fixing plate 7 and the screw hole 5 of the fixing platform 4 in sequence, and finally is threaded into the pre-set screw hole on the wheel hub 1. During this connection process, the fixing plate 7 is fitted onto the shank of the fixing screw 6, and the bottom surface of the fixing plate 7 is always pressed against the top surface of the fixing platform 4. By tightening the fixing screw 6, the fixing plate 7 applies a uniform and stable downward pressure to the fixing platform 4, thereby firmly locking the entire tire pressure monitoring device 3 onto the inner wall of the wheel hub 1.

[0025] The tire pressure monitoring device 3 also has an integrally formed anti-tire sealant protrusion 8. This anti-tire sealant protrusion 8 is arranged around the outside of the sensing core area of ​​the tire pressure monitoring device 3, forming a physical barrier. Specifically, the height of the anti-tire sealant protrusion 8 is higher than the mounting plane of the core electronic components of the tire pressure monitoring device 3. When liquid sealant is injected into the tire, the sealant flowing under the action of centrifugal force will be effectively blocked and isolated by the anti-tire sealant protrusion 8, and will not be able to overflow the protrusion and enter the sensing core area it surrounds. This avoids the sealant from causing chemical corrosion or physical coverage to the internal sensors or circuit boards and other precision components, thus ensuring the long-term stable operation of the tire pressure monitoring device 3.

[0026] To further optimize the overall structure, the two sides of the fixed platform 4 are designed to gradually thin towards the edge. This gradient design not only better matches the inner wall contour of the wheel hub 1 and reduces stress concentration, but also reduces the overall weight to a certain extent. In addition, the contact surface between the tire pressure monitoring device 3 and the valve 2 is an arc spherical structure. This non-rigid spherical fit can effectively buffer the slight shaking that the valve 2 may generate during vehicle operation, reduce the force transmission and interference to the tire pressure monitoring device 3 body. At the same time, this design also helps to shorten the body length of the tire pressure monitoring device 3, making its structure more compact and optimizing the installation space inside the wheel hub 1.

[0027] As a preferred embodiment, in order to ensure that the pressure applied by the fixing plate 7 to the fixing platform 4 is evenly distributed, the contact surface of the fixing plate 7 used to press the fixing platform 4 is a plane. This plane-to-plane contact method avoids stress concentration and can more reliably press the fixing platform 4 firmly onto the inner wall of the hub 1.

[0028] As another preferred implementation, to provide double protection under extreme bumpy conditions and further enhance the reliability of the fixation, the bottom surface of the fixing platform 4 can also be fixed to the inner wall of the wheel hub 1 by adhesive or welding. This rigid or flexible auxiliary connection complements the mechanical locking structure of the fixing screw 6 and the fixing pressure plate 7, making the tire pressure monitor 3 more firmly fixed.

[0029] In one specific structural implementation, the two sides of the fixed platform 4 are preferably thinned towards the edge to achieve a smooth transition with the inner wall arc surface of the wheel hub 1. At the same time, the contact surface between the tire pressure monitor 3 and the valve 2 is preferably an arc spherical structure. This design combination not only optimizes the fit and stability of the installation, but also makes the overall structure more compact.

[0030] Working principle: During installation, the valve 2 is first fixed to the wheel hub 1. Then, the mounting platform 4 of the tire pressure monitoring device 3 is fitted to the inner wall of the wheel hub 1 with the inclined surface of its bottom that matches the curvature of the inner wall of the wheel hub 1. The position of the tire pressure monitoring device 3 can be finely adjusted using the long slotted screw hole 5 on the mounting platform 4 until it achieves the best assembly state with the valve 2. This design solves the installation compatibility problem caused by the difference in wheel hub specifications.

[0031] After adjusting the position, pass the fixing screw 6 through the fixing plate 7 and the screw hole 5 in sequence and screw it into the wheel hub 1. During the tightening of the fixing screw 6, the fixing plate 7 will form a uniform and stable downward pressure on the top surface of the fixing platform 4. Combined with the large-area contact between the fixing platform 4 and the inner wall of the wheel hub 1, the tire pressure monitor 3 is firmly locked, effectively resisting the vibration and centrifugal force during vehicle operation, and avoiding loosening that would affect the accuracy of the monitoring data.

[0032] During vehicle use, if tire sealant is injected into the tire, the anti-tire sealant protrusion 8 integrally formed on the tire pressure monitoring device 3 plays a crucial protective role. It can effectively isolate the liquid sealant flowing due to tire rotation, preventing the sealant from corroding the core components of the sensor, thereby ensuring the long-term operational stability of the tire pressure monitoring device 3. Ultimately, through the coordinated work of the above components, the accurate and continuous monitoring function of tire pressure is achieved.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
