Description

Technical Field

[0001] This utility model belongs to the field of tires and relates to a tire incorporating RFID. Background Technology

[0002] Most existing tire products use RFID electronic tags as tire identification information records, which can be monitored in real time to achieve tire identification and theft prevention, service life recording, usage and maintenance status recording, etc.

[0003] RFID electronic tags are typically embedded during tire manufacturing. Referring to the method of embedding electronic devices in tires disclosed in CN101734112B, the electronic tags are directly embedded inside the tire sidewall or bead. However, during construction and vulcanization, tires are subjected to rolling stretching and internal flow deformation. The tag embedding method of the aforementioned patent is prone to compression deformation or misalignment during rolling stretching, and is prone to displacement during vulcanization, etc., which cannot ensure the accuracy, stability and durability of the electronic tag implantation. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a tire that incorporates RFID.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tire incorporating RFID includes a tire carcass with a multi-layer composite structure. An encapsulation component is disposed between any two adjacent layers in the multi-layer composite structure of the tire carcass. The encapsulation component includes an RFID tag and films disposed on opposite sides of the RFID tag.

[0007] Furthermore, the film is provided with a positioning structure, which includes two protruding ribs that protrude from the surface of the film and are distributed in parallel to each other, and a groove for placing the RFID tag is formed between the two protruding ribs.

[0008] Furthermore, the number of positioning structures is two, and they are respectively disposed on two films. The two positioning structures are centrally symmetrical about the RFID tag.

[0009] Furthermore, the groove and one of the ribs form a first width, and the groove and the other rib form a second width, wherein the first width is greater than the second width.

[0010] Furthermore, the RFID tag includes an antenna made of carbon steel with brass electroplated on its surface, and the film is made of rubber.

[0011] Furthermore, an adhesive layer is provided on the outer surface of the film.

[0012] In summary, the advantages of this utility model are as follows:

[0013] This utility model uses double-sided film to encapsulate RFID tags, embedding the entire encapsulation assembly inside the tire. The film encapsulation effectively fixes the RFID tag, reducing the displacement of the RFID tag during rolling and vulcanization, and providing effective protection for the tag, reducing the deformation of the tag due to external pressure. At the same time, the use of double-sided film allows the entire encapsulation assembly to be more fully integrated with the tire. Attached Figure Description

[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0022] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0023] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0024] This embodiment provides a tire incorporating RFID, referring to... Figure 1 As shown, the tire is manufactured using existing tire production processes. Its structure includes multiple structural layers such as bead 13, triangular rubber, inner liner, ply layer, belt layer, sidewall layer, and tread layer to form the tire carcass. An RFID tag 21 is embedded in the tire carcass to provide electronic storage of data and communication of this data to an external reader.

[0025] The tire carcass structure, in terms of location, includes a tread 11 located on the outer periphery, a bead 13 located on the inner periphery, and a sidewall 12 located between the tread 11 and the bead 13. As a preferred but not necessary practice, the RFID tag 21 is embedded in the sidewall 12 or the bead 13 of the tire carcass during tire construction and before vulcanization, to avoid embedding it in the tread 11 and causing the tread 11 to bulge, so as to maintain the structural integrity of the tire during operation as much as possible and avoid abnormalities.

[0026] As a preferred but not necessary option, the RFID tag 21 is embedded between the sidewall layer and the cord layer of the sidewall 12, or between the sidewall layer and the triangular rubber of the bead 13.

[0027] As a preferred but not necessary practice, the RFID tag 21 is placed perpendicular to the radial direction of the tire.

[0028] The multi-layer composite structure of the tire described in this embodiment is a common composite structure in the prior art, such as the tire structure disclosed in Chinese Invention Patent CN101734112B, so it will not be described in detail here.

[0029] As a preferred but not essential option, the RFID tag 21 described in this embodiment may take the form of the RFID electronic tag disclosed in Chinese Patents 2025203440717, 2024231576859, and 2024231576825, referring to... Figure 5 As shown, all include a carrier plate and antennas disposed at both ends of the carrier plate. However, this utility model does not limit this in any way. In other embodiments, any other RFID electronic tag that can be embedded in a tire can be applied to the scope of protection of this utility model.

[0030] The RFID tag 21 can be directly embedded in the tire body, or the RFID tag 21 can be combined with two films 22 to form an encapsulation component 2, which is embedded in the tire body.

[0031] Reference Figure 2 Two films 22 are arranged opposite each other, and the RFID tag 21 is sandwiched between the two films 22. The opposing side surfaces of the two films 22 are fixed together by adhesive bonding, fusion or other processes to fix the RFID tag 21 between the two films 22.

[0032] During tire construction, the pre-set encapsulation component 2 is placed within the structural layer of the tire carcass. Through rolling and vulcanization in the tire construction process, the film 22 is laminated with the RFID tag 21 and the film 22 is fused with the tire carcass.

[0033] An adhesive layer is provided on the outer surface of the film 22, so that during tire construction, the encapsulation component 2 can be directly adhered and fixed to the surface of any structural layer inside the tire through the adhesive layer, thereby reducing the displacement of the encapsulation component 2 under the influence of external forces during rolling bonding.

[0034] Furthermore, the antenna of the RFID tag 21 is made of carbon steel with a brass-plated surface, and the film 22 is made of rubber. The carbon steel material provides the antenna with excellent strength and fatigue resistance, maintaining the reliability of the antenna under the high-intensity working environment of the tire. During the vulcanization process, the film 22 bonds with the copper on the surface of the antenna, forming a tight composite between the film 22 and the antenna, reducing the possibility of cracks and gaps caused by the separation of the antenna and rubber under the high-intensity working environment of the tire.

[0035] Furthermore, the surface of the film 22 that contacts the RFID tag 21 is also provided with a positioning structure to position the RFID tag 21. The positioning structure includes two protruding ribs 221 that protrude from the surface of the film 22. The two ribs 221 are parallel and spaced apart by a predetermined interval to form a groove 222 for placing the RFID tag 21. The groove 222 has a U-shaped cross-section. When the RFID tag 21 is placed in the groove 222, it naturally falls to the bottom of the U-shape of the groove 222, thus positioning the RFID tag 21 in the groove. The raised ribs 221 are parallel, and their structure forms a thickened and reinforced area on the film 22, thereby providing support on both sides of the RFID tag 21 to better maintain the straight structure of the RFID tag 21 and reduce bending, deformation or displacement during rolling and vulcanization. Furthermore, the raised ribs 221 provide material to both sides of the RFID tag 21, which can more fully fill the gaps around the RFID tag 21 during vulcanization, especially the gaps of the antenna, to achieve a tight and thorough composite between the film 22 and the antenna.

[0036] In other embodiments, reference is made to Figure 3 The positioning structure is provided in one part, located on one of the films 22, and the other film 22 covers the top of the rib 221 to fix the RFID tag 21 in the groove 222.

[0037] In other preferred embodiments, two positioning structures are provided, each disposed on one of the two films 22, and the two positioning structures are staggered during installation, that is, one of the protruding ribs 221 of one positioning structure extends into the groove 222 of the other positioning structure, as shown in the reference. Figure 4 As shown, the two positioning structures are centrally symmetrically distributed with the RFID tag 21 as the center of symmetry, forming a bidirectional symmetrical snap-fit ​​fixation for the RFID tag 21, which better maintains the structure of the RFID tag 21. During the vulcanization process, the ribs 221 flow and fill into the grooves 222 on the opposite side. The four ribs 221 form an all-round wrap around the RFID tag 21, achieving a tighter and more complete composite.

[0038] Furthermore, the rib 221 and groove 222 of the positioning structure are configured as an asymmetrical structure, with a first width separating the groove 222 from one of the ribs 221 (refer to...). Figure 4 The width a) is separated from the rib 221 on the other side by a second width (refer to the width a). Figure 4 The width b) is made such that the first width is greater than the second width, thereby reserving space for the protruding rib 221 on the opposite side to enter.

[0039] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
