Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically a tire. Background Technology

[0002] As the only component of a vehicle in contact with the ground, tires not only bear the vehicle's weight but also perform crucial functions such as cushioning, traction, driving, braking, and steering. Their performance and condition directly affect the vehicle's safety and stability. In actual use, tires are constantly exposed to complex and changing operating conditions, enduring friction from different road surfaces, load variations, and temperature fluctuations. Therefore, extremely high requirements are placed on tire reliability and durability. With the development of vehicle intelligence technology, applying RFID chips to tires for intelligent management has become an important direction for improving tire performance monitoring and vehicle safety.

[0003] Currently, the application of RFID chips in the tire industry aims to achieve intelligent tire management, such as identification, data collection, and transmission. In existing technologies, RFID chips are typically embedded into the tire sidewall using a pre-bonded rubber method. However, this pre-bonded RFID chip is relatively large, often exceeding 4mm in thickness, limiting its implantation to the tire sidewall.

[0004] During vehicle operation, the tire sidewalls continuously bend and deform, causing stress concentration at the location of the implanted RFID chip and exacerbating localized heat generation. Under these harsh working conditions, the RFID chip is highly susceptible to damage, leading to the loss of the tire's RFID function and hindering effective tire monitoring and management. This significantly impacts the reliability and stability of RFID technology in intelligent tire applications. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 In this embodiment of the present invention, a tire includes a tire body 101, sidewalls 108 extending from both sides of the tire body 101, a tread 109 located at the upper center of the tire body 101, a bead 107 located on the sidewall 108 away from the tire body 101, a steel wire ring 104 located inside the bead 107, a belt layer 102 located below the tread 109, shoulder pads 103 located on both sides of the belt layer 102, a cord layer 110 located below the belt layer 102, an airtight layer 105 located below the cord layer 110, the airtight layer 105 extending to both sides to the bead 107, and an RFID module 200 located between the cord layer 110 and the airtight layer 105; the width of the belt layer 102 is greater than the width of the cord layer 110; tire tread patterns are engraved on the surface of the tread 109; the present invention reduces the size of the RFID chip 201 by surface treatment, thus overcoming the limitations of traditional implantation positions. By accurately calculating the tire stress and flexural deformation area, the chip is implanted in the center of the tire, avoiding 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 RFID function throughout the tire's entire life cycle, and achieves continuous and efficient tire identification, data collection and transmission, greatly improving the practicality of RFID technology in intelligent tire applications.

[0027] The RFID module 200 is positioned between the cord layer 110 and the airtight layer 105, or offset 0-10mm to the left or right from the midpoint of the cord layer 110. The RFID module 200 includes an RFID chip 201 and a wrapping material 202, which wraps the surface of the RFID chip 201. The thickness of the RFID chip 201 is 0.5-2mm, and the diameter of the wrapping material 202 is 6-10mm. By wrapping the RFID chip 201 with the wrapping material 202, the overall size of the RFID module 200 is made very small, reducing the impact on tire performance after the RFID module 200 is implanted in the tire.

[0028] The encapsulating material 202 is epoxy resin or rubber. Epoxy resin has excellent insulation and chemical stability, effectively protecting the RFID chip 201 from interference from external electric and magnetic fields, ensuring the accuracy and stability of chip data transmission. Simultaneously, its high strength and corrosion resistance can resist the erosion of various chemicals, extending the service life of the RFID chip 201 in complex environments. Rubber, on the other hand, has excellent flexibility and elasticity, buffering external impacts and preventing damage to the chip due to vibration or compression. Furthermore, rubber has good waterproof properties, preventing moisture intrusion and damage to the chip, ensuring normal operation even in humid environments.

[0029] The wrapping material 202 is bonded to the cord layer 110 and the airtight layer 105 by vulcanization. Vulcanization bonding can form strong and stable chemical bonds, achieving a firm bond between the wrapping material and the cord layer and airtight layer. This firm bond not only enhances the overall structural stability and improves the mechanical performance of the tire, but also effectively prevents the wrapping material from separating or loosening from the cord layer and airtight layer, thereby avoiding safety hazards caused by structural instability.

[0030] The airtight layer 105 consists of a reinforcing mesh layer 1501 and two rubber layers 1052, with the reinforcing mesh layer 1501 bonded between the two rubber layers 1052. The rubber layers 1052 are flexible, elastic, and have good adhesion. The reinforcing mesh layer 1501 makes the airtight layer 105 seal more continuously and stably. When under pressure, the rubber layers 1052 are squeezed into the gaps in the mesh layer, effectively preventing air leakage and maintaining stable internal pressure of the system. The reinforcing mesh layer can disperse stress when the airtight layer 105 is subjected to external forces, preventing damage to the rubber layers and extending the service life of the tire in complex mechanical environments.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
