Description

Rim punching type monitoring structure

Technical Field

The invention relates to a monitoring device, in particular to a rim punching type monitoring structure which can be arranged on a rim in a penetrating way to detect tire monitoring parameters.

Background

The automobile industry is advancing, and many device structures are all equipped with automatic monitoring ware in order to monitor whether the car can maintain good operating performance, and protection driving safety avoids the driving accident. Among these, the most common concern is tire pressure conditions. From 2016, 7/1, taiwan, the sixty-eight regulations on vehicle safety standards are modified, and both newly-shipped vans and coaches must be equipped with a Tire Pressure Monitoring System (TPMS), and when the absolute detected Tire pressure working pressure is reduced to 20%, the system must turn on a light to warn driving, and if the newly-shipped vehicles are not equipped with a Tire pressure detector, the vehicles cannot be led.

When the vehicle is started, the general tire pressure detector can generate a notice symbol on an instrument panel, and when the tire pressure is reduced to 20 percent, the system can light up for warning in a short time to inform driving of insufficient tire pressure of the tire. Currently, tire pressure detectors can be classified into direct type and indirect type according to different measurement methods; the mounting position is divided into an in-tire type or an in-tire type.

The operation principle of the indirect tire pressure detector is that the wheel speed sensor of the ABS/EPS system compares the rotation speed difference of four tires of a vehicle during driving, and when one of the tires is insufficient in pressure and the outer diameter of the tire is reduced, the system can send out an abnormal signal of the tire condition. Because it is not directly used to measure the pressure in the tire, it is called indirect tire pressure detector (WSB TPMS). However, the indirect tire pressure detector cannot provide the tire pressure data, and only provides the tire pressure abnormality warning. The direct tire pressure detector directly installs the tire pressure sensor in the four tires of the vehicle, and can directly display the tire pressure data on the display of the receiver through the system of the receiver, which is easy to read; because the tire Pressure data of each tire can be directly read, the driving safety can be improved, namely, the tire Pressure-Sensor Based TPMS (PSB TPMS) can be called as a direct-Pressure-Sensor-Based TPMS.

The tire pressure detector is installed on the tire valve, i.e. the vehicle owner can buy the detector by oneself, but because not fixed in the tire, is easy to be destroyed and pulled away and steal by the careless person, and under the permanent use, because expose on the valve, receive the wind and shine easily and the structural body is out of shape and embrittled, is whipped and dropped when the tire rotates at a high speed. The tire pressure detector is installed in the tire, integrated with the tire, semi-permanently fixed, generally equipped with a battery, the power usually maintained for 3-5 years, and the vehicle owner can not install the tire pressure detector by himself, can only install through the vehicle maintenance factory, generally will install when the tire is changed.

Disclosure of Invention

At present, automobile repair factories advocate car owners to install in-tire type tire pressure detectors, which are more stable and have higher accuracy than out-tire type tire pressure detectors because they are fixed in the tire. However, since the tire pressure detector in the tire needs to be fixed on the tire frame, and the weight and the volume are usually large, the balance correction is needed after the tire pressure detector is installed, so as to prevent the tire from shaking during the rotation; in addition, because the metal net is often embedded inside the tire, the rim of the vehicle is usually made of metal material, and when the tire pressure detector is disposed inside the tire, the problem of signal shielding often occurs, resulting in incomplete data transmission and reception. Secondly, besides the tire pressure is an important monitoring item, the vehicle conditions such as the rotation speed, the dynamic balance and the static balance of the tire are also important monitoring items.

In view of the above-mentioned drawbacks, the present inventors have devised a rim punching type monitoring structure, which is disposed in a tire, and includes a sensor having a sensor body and a communication module electrically connected to one side of the sensor body. The sensor body is combined on the inner side of a rim body, and an antenna assembly of the communication module penetrates through a through hole in the rim body to be wirelessly connected to a reader.

Further, the sensor body is a vehicle sensor.

Further, the power supply of the sensor is electrically connected to the antenna assembly of the communication module.

Further, the antenna assembly receives the electromagnetic wave signal of the reader to generate a current and a control signal, the current is provided to the power supply through the antenna assembly, and the control signal is provided to a control chip through the antenna assembly.

Further, an airtight rubber is arranged between the antenna assembly and the via hole.

Further, the pressure detecting end of the sensor body is positioned in the tire cavity of the tire.

The rim punching type monitoring structure has the following advantages;

1. the rim punching type monitoring structure can effectively avoid the problem that the tire or the rim shields signals and ensure the integrity of the signals.

2. The rim punching type monitoring structure has small volume and light weight, and can not shake due to overlarge volume and weight when being installed on a tire frame to influence the running of a tire.

3. The rim punching type monitoring structure can effectively monitor the condition of the tire and ensure the driving safety of driving.
