AI Technical Summary

Technical Problem

The existing high-temperature resistant RFID electronic tags have the problem of metal shell interfering with radio frequency signals and reducing working distance. At the same time, the front packaging of the product is fragile and easy to be damaged by impact during use.

Method used

A high-temperature collision-resistant RFID electronic tag is designed, adopting a combined structure of a protection box and a first heat insulation element. The side wall of the protection box is equipped with toothed openings to reduce metal interference, and a protective rod is arranged at the top openings to enhance collision resistance, and a fiberglass cloth is covered on the epoxy resin potting layer to improve impact resistance and waterproof and dustproof performance.

Benefits of technology

It effectively reduces the interference of the metal box to RFID tags, improves working distance and impact resistance, and enhances waterproof and dust-proof sealing performance.
