The present invention will no longer describe the specific circuit control relationship and circuit connection in detail.

[0062] like Figure 1-Figure 3 As shown, the present invention provides an electronic tag embodiment suitable for deformable objects.

[0063] The electronic tag suitable for deformable objects includes a tag body 2 and an antenna part 1, wherein the antenna part 1 includes at least one radiating antenna 11 and a spiral connecting part 12 connected to the radiating antenna; the tag body 2 includes a coupling bracket 20, a circuit board (not shown in the drawings) and a coupling part 21 that forms a signal connection with the circuit board, the coupling bracket 20 is provided with a spiral structure 23, the coupling part 21 is arranged in the spiral structure 23, and the spiral connecting part 12 is arranged in the spiral structure 23. At the working frequency, the spiral connecting part 12 is coupled with the coupling part 21 in the spiral structure 23, so that the radiating antenna 11 forms a signal path with the circuit board.

[0064] Specifically, the coupling bracket 20 is provided with a cavity (not shown in the drawings) in the length direction, and the circuit board is arranged in the cavity. The coupling part 21 can be arranged along the spiral groove 21 on the coupling bracket 20 using a conductive wire. The conductive wire can be a wire with an insulator on the surface or a wire with an exposed surface. The coupling bracket 20 can generally adopt two structures. One is to use a tubular structure, firstly use a conductive wire to wind the conductive wire in a spiral shape on the surface of the tubular structure, and then inject the tubular structure with the spiral conductive wire to form the coupling bracket 21. The surface of the coupling bracket 21 forms a spiral structure consistent with the distribution of the spiral conductive wire, and the spiral structure includes a spiral groove or a spiral hole. The second is to first inject the coupling bracket 20 with a spiral groove, and then wind the conductive wire along the spiral. It is best to make the conductive wire located at the bottom of the spiral groove. In order to ensure the consistency of the position of the spiral groove when the wire is spirally wound, and to have a better coupling signal, when the coupling bracket 21 is formed, positioning grooves (not shown in the drawings) for positioning the wire position are respectively provided at the bottom of the spiral groove.

[0065] Since the tag body 2 and the antenna part 1 are coupled through the spiral spiral connection part and the coupling part 21, the position between the coupling part and the spiral connection part is fixed after the tag body 2 and the antenna part 1 are fixed, and the coupling part and the spiral connection part of the spiral structure are matched with each other through the spiral, and the coupling line is long. When looseness occurs, at least a part of the spiral position between the two always maintains a relatively stable coupling, thereby ensuring the stability of the coupling signal during operation and avoiding signal instability due to the shape during use. It can be widely used on objects that are deformed during use, such as pressure detection on tires.

[0066] As required, the radiating antenna 11 includes a spiral or wavy structure, or can be configured as a structure of other radio frequency signals adapted to its operation. The radiating antennas 11 at both ends of the spiral connection 12 are arranged symmetrically around the spiral connection or in an axisymmetric manner.

[0067] As required, when the radiating antenna 11 is a spiral, the pitch L1 of the spiral structure of the radiating antenna 11 is greater than the pitch L2 of the spiral connecting portion 12; when the radiating antenna 11 is a wavy structure 13, the distance between adjacent wave crests and wave troughs is greater than the pitch of the spiral structure, such as Figure 4 This arrangement can ensure that after the tag body and the antenna part are coupled, at least part of them are always in the best coupling position to avoid being affected by deformation during use. At the same time, it can also ensure the stability of the tag body and the antenna part after they are fixed.

[0068] According to the requirements, the angle of the spiral on the spiral connection part and the spiral on the coupling part is not less than 360 degrees, and the angle of the spiral on the spiral connection part and the spiral on the coupling part is 1080-2160 degrees. The conductive wire includes memory metal.

[0069] As required, the coupling bracket 21 is provided with a cavity (not shown in the drawings) for accommodating a circuit board in the length direction.

[0070] In order to ensure the stability of the connection between the spiral structure and the spiral connection after fixation, when the pitch of the spiral structure is different from that of the spiral connection, the pitch at both ends of the spiral connection is greater than the middle pitch, or the middle pitch is greater than the pitch at both ends; when the screw hole aperture of the spiral structure is different from that of the spiral connection, the screw hole aperture at both ends of the spiral connection is smaller than the middle aperture, or the screw hole aperture at both ends of the spiral connection is larger than the middle aperture. It is also possible to set the screw hole in the middle part of the spiral structure to be smaller than the two ends as needed, and the spiral structure of the smaller screw hole part, such as the spiral angle of the spiral groove is not less than 720 degrees, so that at least two spiral lengths of coupling length can be guaranteed during coupling, thereby improving the reliability of the coupling signal that may be used in a motion scene. As needed, the spiral connection 12 is provided with at least one limiting portion (not shown in the figure), which cooperates with the limiting groove (not shown in the figure) on the spiral groove 23 to avoid the possible deformation of the radiating antenna from affecting the signal coupling between the spiral connection 12 and the coupling part.

[0071] In order to further improve the connection stability, the middle part of the spiral connection part is made of thicker metal or a flatter structure, which can form a good coupling effect after fixation, especially when the antenna part and the tag body are integrally formed by injection molding.

[0072] like Figure 5-6 As shown, the present invention also provides an embodiment of a method for making an electronic label.

[0073] The electronic label making method comprises:

[0074] Step S11 of manufacturing the antenna part, taking a section of conductive metal wire, forming a spiral connection part in a spiral shape in the middle of the conductive metal wire, so that at least one end of the spiral connection part forms a radiating antenna, thereby obtaining the antenna part;

[0075] Step S12 of making a tag body, forming a signal connection between the chip and the circuit board, a coupling bracket is provided on the circuit board, a coupling part having the same structure as the spiral connection part is provided on the coupling bracket, and the coupling part forms an electrical connection with the chip to obtain a tag body;

[0076] In step S13 of electronic tag formation, the manufactured tag body is fixed in the hollow of the spiral connection part, the spiral of the spiral connection part is made consistent with the spiral on the coupling part, and then injection molding is performed to make the coupling distance between the coupling part and the spiral connection part the same, thereby obtaining the electronic tag.

[0077] Specifically, the antenna part and the tag body are of the structure of the above-mentioned embodiment. The angle of the spiral on the spiral connection part and the spiral angle on the coupling part are not less than 360 degrees. The angle of the spiral on the spiral connection part and the spiral angle on the coupling part are 1080-2160 degrees. After the tag body and the antenna part are fixed by injection molding, a spiral groove or a spiral hole is formed between the two, and the coupling part is located in the spiral groove or the spiral hole at the same distance from the spiral connection part. The conductive metal wire includes memory metal and the like. The manufactured electronic tag has all the effects of the above-mentioned antenna part and tag body when they are matched. The coupling signal stability can be guaranteed, and it can better adapt to objects that are deformed during use, such as pressure detection on tires.

[0078] like Figure 7 As shown, the present invention also provides an embodiment of a method for making an electronic label.

[0079] The present invention also provides a method for producing an electronic label, the method comprising:

[0080] In step S11 of manufacturing the antenna part, a section of conductive metal wire is taken and a spiral connection part with a spiral shape is formed in the middle of the conductive metal wire, so that at least one end of the spiral connection part is provided with a radiating antenna;

[0081] Step S12 of making a tag body, forming a signal connection between the chip and the circuit board, setting a coupling bracket on the circuit board, and setting a coupling part which is completely the same as the spiral connection part on the coupling bracket, the coupling part forming an electrical connection with the chip, injection molding the coupling bracket, forming a spiral groove or a spiral hole on the coupling bracket, and the coupling part is distributed along the wall of the spiral groove or the spiral hole, so as to obtain the tag body;

[0082] In step S13 of electronic tag formation, the manufactured tag body is spirally rotated into the interior of the spiral connection part, so that the spiral coupling part in the spiral groove or spiral hole forms a signal coupling loop with the spiral connection part, thereby obtaining an electronic tag.

[0083] Specifically, the antenna part and the tag body are the structures of the above-mentioned embodiment, which will not be described in detail. The manufactured electronic tag has all the effects of the above-mentioned antenna part and tag body when they are matched. The coupling signal stability can be ensured, and it can better adapt to the deformation of the objects during use, such as the pressure detection on the tire.

[0084] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
