Description

tires equipped with sensors

technical field

The invention relates to a structure of a tire and its accessories; in particular, it relates to a tire provided with a sensor.

Background technique

Existing sensors commonly used to detect tires, such as tire pressure sensors, are combined at the air nozzles of the rims, and the air pressure in the tires is measured by the structure in which the sensors are located in the tires. After the aforementioned tire pressure sensor installed on the rim valve senses the air pressure in the tire, it will transmit the air pressure data to the outside, such as the trip computer, and judge whether the tire pressure in the tire is abnormal, and then issue a warning signal to the driver signal.

The above-mentioned tire pressure sensor located at the rim air nozzle can be used to detect the air pressure inside the tire because the tire pressure is the same everywhere inside the tire. However, this type of tire pressure sensor is located close to the rim and far from the tire body, which is more suitable for measuring tire pressure values with equal pressure everywhere, and is relatively limited in measuring other tire values.
