Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a balanced and anti-shaking valve hub fixed built-in tire pressure sensor valve structure. Background Technology

[0002] Tire pressure monitoring systems (TPMS) are an important active safety device for automobiles, capable of monitoring tire pressure in real time and effectively preventing traffic accidents caused by tire malfunctions. Currently, built-in TPMS sensors are widely used in the market due to their advantages such as accurate measurement and resistance to theft and damage. These sensors are typically installed inside the tire and integrated with or fixedly connected to the inflator valve.

[0003] When a vehicle travels at high speed, the wheels rotate at high speed. The tire pressure sensor, installed inside the wheel hub, is a component with a certain mass and is inevitably subjected to a huge centrifugal force. In existing installation structures, the sensor and its associated fasteners are mostly fixed to the wheel hub through only one connection point: the valve stem. The entire sensor assembly forms a cantilever beam structure relative to the root of the valve stem.

[0004] In this cantilevered fixed structure, a continuous and strong centrifugal force acts on the sensor's center of mass, generating a torque that attempts to cause it to swing outward. Lacking additional support points to balance or counteract this torque, the entire sensor assembly is prone to minute vibrations and swaying during high-speed rotation. This long-term instability not only accelerates the fatigue aging of the sensor's mounting structure, leading to loose connections or even breakage and affecting the accuracy of monitoring data, but more seriously, the swaying itself also disrupts the dynamic balance of the wheels, posing a potential hazard to driving safety.

[0005] Therefore, this utility model proposes a balanced and anti-shaking valve hub fixed built-in tire pressure sensor valve structure to solve the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a balanced anti-shaking valve hub fixed built-in tire pressure sensor valve structure. It aims to improve the problem that the built-in tire pressure sensor in the existing balanced anti-shaking valve hub fixed built-in tire pressure sensor valve structure is only fixed to the wheel hub by a single point cantilever through the valve. When the wheel rotates at high speed, it is prone to shaking due to the lack of effective support, resulting in structural instability and safety hazards.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a balanced and anti-shaking valve hub fixing valve structure with built-in tire pressure sensor, including a hub with a valve hole, a valve inserted through the valve hole, a tire pressure monitor, an arc-shaped displacement groove, a reinforcing and stabilizing rubber coating, and a screw with a through hole in the middle. Among them, the reinforced and stabilizing rubber is fixedly connected to the outer surface of the arc displacement groove, and the reinforced and stabilizing rubber is provided with a cavity for accommodating the tire pressure monitor, and a support point is integrally formed on it. Furthermore, the through-hole screw passes through the arc-shaped displacement groove and is threaded to the inner end of the air nozzle, locking the arc-shaped displacement groove and the reinforcing and stabilizing rubber coating fixed thereon to the air nozzle. In the installed state, the support point abuts against the inner wall of the wheel hub.

[0008] Preferably, the arc-shaped displacement groove is provided with a displacement elongated hole through which a central through-hole screw can pass.

[0009] Preferably, the side of the enhanced stabilizing package GPIO facing the inner wall of the hub is formed as an arc surface that matches the inner wall of the hub.

[0010] Preferably, the end of the reinforcing and stabilizing coating furthest from the air nozzle has a gradually thinning structure.

[0011] Preferably, the structure further includes a sleeve pressure plate, which is sleeved on the air nozzle on the outside of the wheel hub and pressed against the outer surface of the wheel hub.

[0012] Preferably, the intermediate through-hole screw has a through hole for inflation along its axial direction.

[0013] Preferably, an airtightness detection hole is provided on the outer side of the wheel hub.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting an arc-shaped displacement groove with a displacement elongated hole, and cooperating with an integrally formed support point on the reinforced and stable rubber coating, the problem of poor compatibility with different specifications of wheel hubs during installation of existing built-in tire pressure sensors, and the easy shaking that occurs when the tire rotates at high speed after installation, resulting in structural instability, is solved. The technical effect of flexibly adapting to a variety of wheel hubs, achieving a balanced and stable structure after installation, and effectively preventing shaking is achieved.

[0015] 2. In this utility model, by designing the side of the reinforcing and stabilizing rubber coating facing the wheel hub as an arc surface and designing the end away from the valve stem as a gradually thinning structure, the problems of poor adhesion between the sensor and the inner wall of the wheel hub after installation and easy damage to the sensor by the tire bead during tire installation and removal are solved in the prior art. The technical effect of achieving tight adhesion with the wheel hub, effective protection of the sensor, and improved product durability is achieved.

[0016] 3. This utility model solves the problem of complicated inflation operation process after the installation of some existing built-in sensors by designing the middle screw used to lock and fix each component as a structure with a central through hole. It achieves the technical effect of integrating the fastening function and the inflation function into one, simplifying the operation and improving the ease of use. Attached Figure Description

[0019] 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.

[0020] Reference Figures 1-5 This utility model provides a balanced and anti-shaking valve hub fixing built-in tire pressure sensor valve structure, which aims to solve the problems of poor compatibility during installation, easy shaking after installation leading to structural instability, and easy scratching and damage during tire installation and removal in the prior art.

[0021] The basic mounting carrier for this balanced, anti-shaking valve hub-fixed tire pressure sensor valve structure is the wheel hub 1, which has a valve hole 2 for mounting the valve. The valve 5 passes through the valve hole 2, so that part of the valve 5 is exposed on the outside of the wheel hub 1 for inflation, and the other part extends to the inside of the wheel hub 1 for fixing internal components. The core innovation of this structure lies in a monitor support assembly fixed to the inner end of the valve 5. This monitor support assembly includes an arc-shaped displacement groove 6, a reinforcing and stabilizing rubber coating 8, and a central through-hole screw 7. The reinforcing and stabilizing rubber coating 8 is fixedly connected to the outer surface of the arc-shaped displacement groove 6, and the reinforcing and stabilizing rubber coating 8 is provided with a feature for accommodating and fixing the tire. The tire pressure monitoring device 3 is housed in a cavity. The central through-hole screw 7 passes through the arc-shaped displacement groove 6 and is threaded to the inner end of the valve stem 5. By tightening the central through-hole screw 7, the arc-shaped displacement groove 6 and the reinforcing and stabilizing rubber coating 8 fixed thereon can be firmly locked onto the valve stem 5 as a whole. In order to achieve structural balance and prevent it from shaking, the reinforcing and stabilizing rubber coating 8 is specially integrally formed with a support point 9. When the entire structure is installed in place, the end of the support point 9 will abut against the inner wall of the wheel hub 1, thereby forming a stable support for the entire monitoring device bearing component, effectively balancing the force it experiences when the tire rotates at high speed, and preventing it from swinging or loosening.

[0022] The arc-shaped displacement groove 6 is a metal part with a specific curvature, on which a long displacement hole is provided for the through-hole screw 7 to pass through. During installation, the arc-shaped displacement groove 6 is fitted onto the air nozzle 5, and the screw portion of the through-hole screw 7 passes through this long displacement hole. The design of this long displacement hole allows the arc-shaped displacement groove 6 to be finely adjusted relative to the axis of the air nozzle 5 along the length of its long hole before being finally locked by the through-hole screw 7. At the same time, the through-hole screw 7 not only acts as a fastener to lock the arc-shaped displacement groove 6 onto the air nozzle 5, but its screw diameter is also precisely matched with the width of the long displacement hole, ensuring clear guidance during adjustment and no excess clearance after locking. This sliding adjustment mechanism between the screw and the long displacement hole... The structure ensures that the installation position of the entire monitor support component can be flexibly adjusted, thereby accurately adapting to the actual height or position differences of the valve hole 2 on different wheel hubs 1. This ensures that the reinforcing and stabilizing rubber coating 8 and its support points 9 can accurately form reliable contact with the inner wall of the wheel hub 1, greatly improving the versatility and installation reliability of the entire device. In addition, to further enhance the installation stability of the valve 5 from the outside of the wheel hub 1, the structure also includes a sleeve pressure plate 4. The sleeve pressure plate 4 is fitted onto the valve 5 on the outside of the wheel hub 1 and pressed tightly against the outer surface of the wheel hub 1, working together with the internal monitor support component to form a double fixation effect. An air tightness detection hole 10 can also be provided on the outside of the wheel hub 1 to assist in detecting the air tightness of the tire.

[0023] As a preferred embodiment, to ensure the monitor mounting assembly fits better against the inner wall of the hub 1 and enhances the tightness and stability after installation, please refer to... Figure 2 The side of the reinforcing and stabilizing rubber coating 8 facing the inner wall of the hub 1 is specially shaped into an arc surface. The curvature of this arc surface matches the curvature of the inner wall of the conventional hub 1. This shape matching allows the two to achieve a large-area close contact after installation, eliminating stress concentration or installation gaps that may be caused by shape mismatch.

[0024] As another preferred embodiment, in order to effectively protect the tire pressure monitoring system 3 and its supporting structure during maintenance scenarios such as tire removal and installation, and to prevent them from being damaged by the tire bead, please refer to... Figure 3 and Figure 5 The end of the reinforcing and stabilizing rubber coating 8 that is away from the valve stem 5, that is, the end that extends toward the center of the tire interior, is designed with a gradually thinning structure. This gradually thinning structure makes the thickness of its end gradually decrease, forming a smooth slope transition. After installation, this gradually thinning end will naturally press against and close to the inner surface of the hub 1, thereby avoiding the formation of a raised step that is easily scratched, significantly improving the product's durability and adaptability to complex working conditions.

[0025] In another preferred embodiment, to simplify the inflation process and improve ease of use, the central through-hole screw 7 is machined with a through hole running through both ends along its own central axis; the inner wall of the through hole may be threaded, and its size and structure are adapted to the interface of a standard inflation device. In this way, when it is necessary to inflate the tire, the operator does not need to disassemble the device at all, and can directly connect the inflation device to the exposed port of the central through-hole screw 7. The gas can then flow directly into the valve 5 and into the tire through this through hole, thus realizing the integration of fastening and inflation functions.

[0026] Working principle: During installation, firstly, the valve 5 is passed through the valve hole 2 of the wheel hub 1, and the outer side of the wheel hub 1 is initially reinforced by the sleeve pressure plate 4. Next, on the inner side of the wheel hub 1, the monitoring device bearing assembly (i.e., the combination of the reinforcing and stabilizing rubber 8 and the arc-shaped displacement groove 6) integrating the tire pressure monitoring device 3 is fitted onto the inner end of the valve 5. At this time, according to the actual size of the wheel hub 1, the position of the entire monitoring device bearing assembly can be adjusted by sliding along the displacement elongated hole on the arc-shaped displacement groove 6 until the support point 9 on it reliably abuts against the inner wall of the wheel hub 1. After the position is determined, the central through-hole screw 7 is passed through the displacement elongated hole and screwed into the valve 5, and gradually tightened. During the tightening process, the head of the central through-hole screw 7 will press against the arc-shaped displacement groove 6, and the strong axial locking force will firmly lock the arc-shaped displacement groove 6, the reinforcing and stabilizing rubber 8 and the valve 5 into a whole. At the same time, the abutment relationship between the support point 9 and the inner wall of the wheel hub 1 provides radial stable support.

[0027] After installation, due to the presence of support point 9, the complex forces such as centrifugal force experienced by the entire monitoring device bearing assembly during high-speed tire rotation are effectively balanced and dispersed, preventing structural swaying and fatigue damage. At the same time, the curved design of the reinforced stabilizing rubber coating 8 ensures a tight fit with the inner wall of the wheel hub 1, further enhancing the overall stability of the structure. Its gradually thinning design provides effective physical protection for the tire pressure monitoring device 3 during tire installation and removal. When inflation is required, it can be operated directly through the through hole in the center of the through-hole screw 7. The gas flows sequentially through the through hole, the internal channel of the valve 5, and finally into the tire. The entire process does not require disassembly of any parts, and the tire pressure monitoring device 3 continuously monitors the air pressure inside the tire.

[0028] 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.
