[0022] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0023] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0024] like Figures 1 to 5As shown, the present invention provides a tire electronic tag with a new structure. The tire electronic tag is composed of a first protective layer 1, a second protective layer 2, an Inlay layer 3 and a release paper 4. Among them, the first protective layer 1 and the second protective layer 2 are made of PI material. The Inlay layer 3 is a prefabricated electronic tag, which is composed of an antenna 31, a dielectric substrate 34 and a tag chip 35. The dielectric substrate 34 is made of PI material. The antenna 31 is formed on the dielectric substrate 34 by etching and other processes, and is composed of a feed ring 32 and two antenna arms 33. The tag chip 35 is mounted on the two feeding points of the feed ring 32 by conductive adhesive and other materials to form a conductive connection.

[0025] The first protective layer 1, the second protective layer 2, and the Inlay layer 3 are stacked in sequence and attached by hot melt adhesive. The back of the Inlay layer is attached to the release paper 4 after adhesive is applied. When in use, the release paper 4 is torn off to complete the initial fixation of the tire electronic tag in the tire by the adhesive.

[0026] In the middle of the second protective layer 2, above the label chip 35, there is a chip avoidance hole 21 with a diameter of 4 mm, and the thickness of the second protective layer 2 is 150 μm, which is greater than the height of the label chip 35, and is used to protect the label chip 35 protruding from the Inlay layer 3 from external force.

[0027] Two fixing holes 5 with a diameter of 3 mm are made in the middle of the feed ring 32. The fixing holes 5 can be made after the tire electronic tag is stacked and pasted or directly made when each material layer is processed, and penetrate the first protective layer 1, the second protective layer 2 and the Inlay layer 3 of the tire electronic tag. When the tire electronic tag is heated, the hot melt adhesive of the tire will flow into the fixing hole 5; after cooling and solidifying, the tire electronic tag is fixed on the tire. Preferably, the distance between the two fixing holes 5 and the chip avoidance hole 21 is more than 1.25 mm to prevent the glue from flowing into the chip avoidance hole 21 and causing damage to the tag chip 35.

[0028] In this embodiment, the length of the tire electronic tag is 40 mm and the width is 8 mm; the antenna line type of the Inlay layer 3 is U4660 as an example; the first protective layer 1 and the second protective layer 2 are both made of PI material. PI material is a preferred material, which has the advantages of high temperature resistance, low temperature resistance (its long-term use temperature range is -269℃ to 260℃), high mechanical strength, excellent insulation performance, flame retardancy, chemical stability, etc., and is suitable for the working environment of the tire.

[0029] In specific applications, the line shape of the antenna 31 can be other line shapes suitable for tire electronic tags. The thickness of each material layer can be adjusted. Preferably, the thickness of the first protective layer 1 is 50 to 150 microns; the thickness of the second protective layer 2 is 150 to 250 microns, and the thickness of the Inlay layer 3 is 50 to 150 microns. The position and size of the chip avoidance hole 21 and the fixing hole 5 can be adjusted according to the antenna line shape. Preferably, the diameter of the chip avoidance hole 21 of the Inlay layer 3 is 3 to 8 mm; the diameter of the fixing hole 5 is 2 to 5 mm; the spacing between the chip avoidance hole 21 and the fixing hole 5 is not less than 1.25 mm. The release paper is obtained through procurement, and its thickness is determined by the purchased material, which is not specifically described.

[0030] The tire electronic tag can effectively prevent displacement by punching a fixing hole in the feed ring and fixing it with glue. In addition, because the fixing hole is close to the chip, a certain structural strength is provided, which can effectively protect the tag chip from external forces. A multi-layer protective layer is also used, and a chip avoidance hole is set above the tag chip in the middle protective layer, which can effectively protect the tag chip from external forces, so as to improve its yield rate and service life.

[0031] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
