Description

Technical Field

[0001] The present invention relates to the technical field of tires, and specifically to a tire. Background Art

[0002] As the only component of a vehicle in contact with the ground, a tire not only bears the weight of the vehicle but also undertakes important functions such as buffering, traction, driving, braking, and steering. Its performance and condition are directly related to the safety and stability of vehicle driving. During actual use, the tire is in a complex and changeable working condition environment for a long time, undergoing multiple tests such as friction on different road surfaces, load changes, and temperature fluctuations. Therefore, extremely high requirements are placed on the reliability and durability of the tire. With the development of vehicle intelligent technologies, applying RFID chips to tires to achieve intelligent management has become an important direction for improving tire performance monitoring and vehicle safety levels.

[0003] Currently, the application of RFID chips in the tire field aims to achieve intelligent management of tires, such as functions like identity recognition, data collection, and transmission. In the prior art, RFID chips are usually implanted into the tire sidewall by means of rubber pre-lamination. However, the size of the RFID chip after pre-lamination is relatively large, and its thickness often exceeds 4 mm. Limited by the size, it can only be implanted into the tire sidewall.

[0004] During vehicle driving, the tire sidewall continuously flexes and deforms, resulting in stress concentration at the position of the implanted RFID chip, and at the same time, local heat generation intensifies. In such a harsh working environment, the RFID chip is extremely prone to damage, thereby causing the loss of the RFID function of the tire and being unable to effectively monitor and manage the tire, greatly affecting the reliability and stability of RFID technology in the intelligent application of tires. Summary of the Invention

[0005] The purpose of the present invention is to provide a tire to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0016] As a further solution of the present invention: the airtight layer consists of a reinforcing mesh layer and two rubber layers, and the reinforcing mesh layer is bonded between the two rubber layers.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By surface treatment of the RFID chip, the present invention reduces the size and breaks through the traditional implantation position limitation. Through precise calculation of the tire stress and the flexure deformation area, the chip is implanted in the center of the tire, avoiding the stress concentration and local heat generation areas on the sidewall.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 3 , in the embodiment of the present invention, a tire includes a carcass 101, bead portions 108 extend on both sides of the carcass 101, a tread 109 is provided in the middle at the upper end of the carcass 101, a bead 107 is provided on the side of the bead portion 108 away from the carcass 101, a bead wire 104 is provided in the bead 107, a belt layer 102 is provided below the tread 109, bead filler rubbers 103 are provided on both sides of the belt layer 102, a ply 110 is provided below the belt layer 102, an inner liner 105 is provided below the ply 110, the inner liner 105 extends to the bead 107 on both sides, and an RFID module 200 is provided between the ply 110 and the inner liner 105; the width of the belt layer 102 is greater than the width of the ply 110; tire tread patterns are engraved on the surface of the tread 109; in the present invention, by surface treatment of the RFID chip 201, the size is reduced, breaking through the traditional implantation position limitation. After accurately calculating the tire stress and flexing deformation area, the chip is implanted in the center of the tire, avoiding the stress concentration and local heat generation areas on the sidewall. This design reduces the risk of chip damage, significantly improves its reliability and stability, ensures the stable operation of the RFID function throughout the tire life cycle, realizes continuous and efficient tire identification, data collection and transmission, and greatly improves the practicality of RFID technology in tire intelligent applications.

[0027] The RFID module 200 is placed at the middle position between the ply 110 and the inner liner 105 or offset 0 - 10 mm to the left or right with the midpoint of the ply 110 as the reference point; the RFID module 200 includes an RFID chip 201 and a packaging material 202, and the packaging material 202 wraps the surface of the RFID chip 201; the thickness of the RFID chip 201 is 0.5 - 2 mm; the diameter of the packaging material 202 is 6 - 10 mm; by wrapping the RFID chip 201 with the packaging material 202, the overall volume of the RFID module 200 is extremely small, reducing the impact on the tire performance after implanting the RFID module 200 into the tire.

[0028] The wrapping material 202 is epoxy resin or rubber; epoxy resin has good insulation and chemical stability, which can effectively protect the RFID chip 201 from external electric and magnetic fields, ensuring the accuracy and stability of chip data transmission. At the same time, its high strength and corrosion resistance can resist the erosion of various chemical substances and extend the service life of the RFID chip 201 in complex environments. Rubber, on the other hand, has excellent flexibility and elasticity, which can buffer external impact forces and prevent the chip from being damaged due to vibration or extrusion. In addition, rubber has good waterproof performance, which can prevent moisture from invading and damaging the chip, ensuring the normal operation of the chip in humid environments.

[0029] The wrapping material 202 is adhesively bonded to the cord layer 110 and the airtight layer 105 by vulcanization; vulcanization adhesion can form strong and stable chemical bonds, enabling a firm bond between the wrapping material and the cord layer and the airtight layer. This firm bond not only enhances the stability of the overall structure and improves the mechanical properties of the tire, but also effectively prevents separation or loosening between the wrapping material and the cord layer and the airtight layer, thus avoiding potential safety hazards caused by structural instability.

[0030] The airtight layer 105 consists of a reinforcing mesh layer 1501 and two rubber layers 1052, and the reinforcing mesh layer 1501 is bonded between the two rubber layers 1052; the rubber layer 1052 is flexible, elastic and has good conformability. The reinforcing mesh layer 1501 makes the airtight layer 105 more continuous and stable in sealing. When pressurized, the rubber layer 1052 is extruded into the voids of the mesh layer, effectively preventing air leakage and maintaining the stability of the internal pressure of the system. The provided reinforcing mesh layer can disperse stress when the airtight layer 105 is subjected to external forces, prevent the rubber layer from being damaged, and extend the service life of the tire in complex mechanical environments.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Although this specification is described in terms of embodiments, not every embodiment contains only one technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
