Radio frequency identification electronic label used for tyre

Abstract

The present invention relates to a radio frequency identification electronic label used for a tyre. The radio frequency identification electronic label comprises an electronic label and a packaging unit, an electronic label chamber of a preset size is arranged inside the packaging unit and is used to accommodate the electronic label. According to the radio frequency identification electronic label used for the tyre of the present invention, by setting the electronic label chamber of the preset size inside the packaging unit, the electronic label is located in the electronic label chamber without restraints, and the situation that an RFID signal is not shielded and interfered, is guaranteed. The RFID electronic label can slide and reset in the electronic label chamber integrally when the tyre operates, so that the situations that antennas break due to the severe distortion at the side of the tyre, and the equal lengths of the antennas change due to the tensile forces, can be avoided, and the stability of the radio frequency signal is guaranteed.

Description

technical field [0001] The invention relates to the technical fields of rubber machinery and electronic information, in particular to a radio frequency identification electronic tag for tires. Background technique [0002] As one of the key safety parts of automobiles, tires have problems of identification and management. Existing tire traceability marks generally use a barcode attached to the tire outer sidewall plus sidewall information to store various information of the tire. Once the tire is worn and cannot be seen visually, the information is completely lost. The radio frequency identification RFID electronic tag for tires is an electronic device used to store tire identification information and has wireless access functions. RFID technology is the core foundation of the Internet of Things. The application of automotive tire products will promote the Internet of Things management of tire product life cycle information from manufacturing, storage, sales to use, mainten...

On the other hand, the existing RFID electronic tags are mostly composed of three parts: a radio frequency module, an antenna, and an electronic tag substrate. The structural types of the two types of RFID electronic tag antennas have their own functional defects: one is the retractable spring. In use, due to the non-equal expansion and contraction of the sidewall part during bending and deformation, the length difference between the antennas at both ends of the radio frequency module is too large, which affects the radio frequency signal; The bending deformation of the side causes tearing and scrapping
