Tire pressure sensor with wheel balance function and wheel balance system

Abstract

The invention discloses a tire pressure sensor with the wheel balance function and a wheel balance system. The tire pressure sensor with the wheel balance function is used for a wheel which is provided with a wheel ring and a tire, air pressure space is formed between the tire and the wheel ring, and the wheel ring is provided with an air nozzle communicating with the air pressure space; the tirepressure sensor comprises a body and a sensing module, and the body is movably arranged in the air pressure space and is provided with accommodating space; the sensing module is arranged in the accommodating space, and a sensing unit of the sensing module is used for sensing the gas pressure in the air pressure space and producing a pressure signal; and a central processing unit of the sensing module receives the pressure signal, the pressure signal is outwards transmitted wirelessly through a wireless transmission unit of the sensing module. The tire pressure sensor with the wheel balance function can effectively reduce the vibration and shaking problem due to uneven wheel weight during wheel travelling so as to achieve the effect of wheel balance.

Description

technical field [0001] The invention relates to the related field of tire pressure sensing of wheels, in particular to a tire pressure sensor and a wheel balancing system with a wheel balancing function. Background technique [0002] The tire pressure sensing system is an electronic system installed on the wheel to sense whether the air pressure of the tire is sufficient. Know the changes in tire pressure to reduce traffic accidents caused by over-inflated or under-inflated tires. [0003] The tire pressure sensing system can be divided into indirect type and direct type according to the operation mode. Among them, the indirect tire pressure sensing system does not directly sense the tire pressure of the tire, but senses the rotation speed of the wheel. However, the indirect tire pressure sensing system cannot provide the driver with the actual tire pressure value. [0004] In addition, the direct tire pressure sensing system, which has a sensor with signal transmission f...

AI Technical Summary

Problems solved by technology

Among them, the indirect tire pressure sensing system does not directly sense the tire pressure of the tire, but senses the rotation speed of the wheel. If the tire pressure is abnormal, the driver will be reminded. However, the indirect tire pressure sensing system cannot provide the driver with the actual tire pressure value.

[0004] In addition, the direct tire pressure sensing system, which has a sensor with signal transmission function, can provide the actual tire pressure value of the driver's wheel. Among them, according to the installation method, there are two types: the tire outside type and the inside type. The air nozzle installed on the wheel can be easily installed by the car owner. However, due to the weight of the sensor itself, locking it on the air nozzle will cause uneven distribution of the wheel mass, which will affect the balance of the wheel. In addition, the sensor needs to be disassembled when filling air, and there will be bumps. Risk of Bad Sensors

[0005] When the vehicle is moving, the structure of the rubber air nozzle combined with the tire outer sensor will shake, and the long-term operation of the wheel will cause the rubber body of the rubber air nozzle to be at risk of breaking

In addition, the in-tire sensor is installed in the rim of the wheel, and the tire needs to be disassembled for installation. Therefore, it can only be installed by a car maintenance factory. After installation, the tire needs to be rebalanced, and the operation is cumbersome.
