The second protective layer is provided with a chip avoidance hole above the tag chip in the prefabricated electronic tag layer. Two fixing holes are provided on both sides of the chip avoidance hole, penetrating the first protective layer, the second protective layer, and the prefabricated electronic tag layer.

[0008] Furthermore, the diameter of the fixing hole is 2 to 5 mm.

[0009] Furthermore, the distance between the chip avoidance hole and the fixing hole is not less than 1.25 mm.

[0010] Furthermore, the materials of the first protective layer and the second protective layer are PI materials.

[0011] Furthermore, the thickness of the first protective layer is 50 to 150 microns.

[0012] Furthermore, the thickness of the second protective layer is 50 to 150 microns.

[0013] Furthermore, excluding the thickness of the label chip, the thickness of the prefabricated electronic label layer is 50 to 150 microns.

[0015] The tire electronic tag of this utility model has the following advantages:

[0016] This tire electronic tag forms a fixing hole by punching a hole in the feed ring and fixes it with glue, which can effectively prevent displacement.

[0022] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals 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 novel tire electronic tag structure. The tire electronic tag comprises a first protective layer 1, a second protective layer 2, an inlay layer 3, and a release paper 4. The first and second protective layers 1 and 2 are made of PI material. The inlay layer 3 is a prefabricated electronic tag consisting 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 through etching and other processes and consists of a feed ring 32 and two antenna arms 33. The tag chip 35 is attached to the two feeding points of the feed ring 32 using materials such as conductive adhesive to form a conductive connection.

[0025] The first protective layer 1, second protective layer 2, and inlay layer 3 are stacked in sequence and attached using hot melt adhesive. The back of the inlay layer is adhesive-coated and then attached to a release paper 4. When in use, the release paper 4 is removed to allow the tire electronic tag to be initially fixed to the tire using 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 microns, 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 3mm diameter fixing holes 5 are located in the center of the feed loop 32d. These fixing holes 5 can be created after the tire electronic tag is laminated or directly during the processing of each material layer. They penetrate the first protective layer 1, second protective layer 2, and inlay layer 3 of the tire electronic tag. When the tire electronic tag is heated, the tire's hot melt adhesive flows into the fixing holes 5, solidifies after cooling, and secures the tire electronic tag to the tire. Preferably, the distance between the two fixing holes 5 and the chip avoidance hole 21 is at least 1.25mm to prevent adhesive from flowing into the chip avoidance hole 21 and damaging the tag chip 35.

[0028] In this embodiment, the tire electronic tag is 40 mm long and 8 mm wide. The antenna line type of the inlay layer 3 is U4660, for example. Both the first protective layer 1 and the second protective layer 2 are made of PI material. PI is a preferred material, offering high and low temperature resistance (its long-term operating temperature range is -269°C to 260°C), high mechanical strength, excellent insulation, flame retardancy, and chemical stability, making it suitable for the tire's operating environment.

[0029] In specific applications, the linear profile of antenna 31 can be other linear profiles 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 linear profile. Preferably, the diameter of the chip avoidance hole 21 in the inlay layer 3 is 3 to 8 mm; the diameter of the fixing hole 5 is 2 to 5 mm; and the spacing between the chip avoidance hole 21 and the fixing hole 5 is not less than 1.25 mm. The release paper is purchased, and its thickness is determined by the purchased materials and is not specified here.

[0030] This tire electronic tag forms a fixing hole by punching a hole in the feed ring and fixes it with glue, which can effectively prevent displacement. Because the fixing hole is close to the chip, it provides a certain structural strength and can effectively protect the tag chip from external forces. It also adopts multiple protective layers and sets a chip avoidance hole above the tag chip in the middle protective layer, which can effectively protect the tag chip from external forces, thereby improving its yield rate and service life.

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