Description

Technical Field

[0001] This utility model relates to the field of tire technology, and more specifically, to an off-road tire. Background Technology

[0002] Tires are components used in heavy-duty vehicles such as cars and bicycles to connect the vehicle to the ground, support the vehicle's weight, and provide cushioning and shock absorption. Tires are typically made of materials such as rubber, and their quality directly affects the vehicle's driving performance, safety, and ride comfort. Off-road tires are suitable for driving in outdoor environments and typically include highway tires, all-terrain tires, and mud tires. A search revealed a utility model patent with publication number CN216268492U, which discloses a novel off-road tire. The tire includes a carcass with treads fixedly connected to its surface. A cord layer is located on the inner side of the carcass. A nylon belt layer is bonded to the surface of the cord layer. A puncture-resistant layer is bonded to the surface of the nylon belt layer. A heat-dissipating layer is bonded to the surface of the puncture-resistant layer. An anti-wear layer is bonded to the surface of the heat-dissipating layer. A first guide groove is formed on the surface of the carcass. This invention utilizes the cross-connection between steel wires to facilitate tire protection, preventing sharp objects from penetrating the tire surface and extending its service life. The connection between the heat dissipation layer and the anti-wear layer improves the overall performance of the tire. The first and second guide grooves enhance the overall drainage effect, significantly reducing slippage caused by water and improving grip. However, in existing technologies, tire pressure is difficult to monitor during use, making the tire less usable. Furthermore, while increasing the volume ratio of grooves in the tire tread structure improves snow performance, it also reduces the strength of individual tread blocks, leading to decreased circumferential rigidity. In particular, many people choose to lower tire pressure to further enhance traction, but this further weakens circumferential rigidity. During driving, this reduced rigidity increases tire heat generation, reduces tread block durability, and increases the likelihood of tread block cracks and chipping. Additionally, reduced rigidity increases tire response lag, reducing handling performance. Therefore, improvements are needed. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide an off-road tire that can detect tire pressure and improve snow performance while ensuring the rigidity of the tread blocks, ensuring the tire's traction performance, and avoiding phenomena such as reduced durability, tread block cracking, chipping, and tread bottom cracking caused by increasing groove volume.

After the slider moves to the designated position, the air pressure detector, fixing block and slide groove are moved to the designated position in the tire body. Then the slider is moved into the slide groove, thereby limiting the components such as air pressure detector, thereby installing the air pressure detector, thereby enabling the air pressure detector to detect the tire pressure, making the tire easy to use.

[0015] (2) In this utility model, by designing components such as the first tread groove, the second tread groove, the third tread groove, the fourth tread groove, the fifth tread groove and the sixth tread groove, the tread is divided into multiple blocks of similar size by grooves at different angles. The rigidity of each tread block is relatively uniform, avoiding local heat generation caused by large differences in rigidity, which could lead to cracks or chips in the tire. In each tread block, a combination of 3D sipes and 2D sipes is used to improve the grip performance of the tread block on snowy roads while ensuring the rigidity of the tread block. The self-cleaning design of the groove bottom can protect the groove bottom from cuts and punctures while improving drainage, mud removal and stone removal performance, dispersing local stress, avoiding stress concentration, and improving the appearance grade of the tire.

[0041] In this embodiment, the second spring 2218 is designed so that the locking block 2215 has an elastic force.

[0042] Working principle: Before using the tire, pull handle 227 to move away from connecting seat 228. The movement of handle 227 moves pull rod 226, which in turn moves connecting block 2213 and support ring 225. The movement of connecting block 2213 moves slot 2214, causing slot 2214 to misalign with slot 2215, which in turn moves slot 2215 towards second spring 2218. The movement of slot 2215 moves sliding groove 2216, compressing second spring 2218. The movement of support ring 225 moves guide block 2211 and slider 224, compressing first spring 229. After slider 224 moves to the designated position, it moves air pressure detector 221, fixing block 222, and sliding groove 223 towards the tire. The handle 227 is released from the designated position within the main body 21. The elastic force of the first spring 229 pushes the support ring 225 to move. The movement of the support ring 225 drives the pull rod 226, guide block 2211, and slider 224 to move. The movement of the pull rod 226 drives the connecting block 2213 and handle 227 to move. The movement of the connecting block 2213 drives the slot 2214 to move. After the slider 224 moves into the slide groove 223, the elastic force of the second spring 2218 pushes the locking block 2215 to move. The movement of the locking block 2215 drives the slide groove 2216 to move. The locking block 2215 moves into the slot 2214, thereby limiting the components such as the air pressure detector 221, thereby installing the air pressure detector 221, and enabling the air pressure detector 221 to detect the tire pressure, making the tire easy to use.

[0043] The tire tread structure consists of the first tread groove 1, the second tread groove 2, the third tread groove 3, the fourth tread groove 4, the fifth tread groove 5, the sixth tread groove 6, the seventh tread groove 7, the first block pattern 11, the second block pattern 12, the third block pattern 13, the fourth block pattern 14, and the first decorative pattern 8 and the second decorative pattern 9. The self-cleaning design of the groove bottom consists of the bottom of the shoulder groove 111 and the bottom of the center groove 112. The tread has 8 block patterns: the first block pattern 11, the second block pattern 12, the third block pattern 13, the fourth block pattern 14, and the first decorative pattern 8 and the second decorative pattern 9. 2. The third and fourth tread blocks (13 and 14), the first and second decorative patterns (8 and 9) on both sides of the shoulder, and the tread groove bottoms (111 and 112) on the shoulder and center, are arranged alternately in a circumferential direction. Each tread block is designed with 2D and 3D sipes. While increasing the volume of the tread grooves, the rigidity of each tread block is balanced. The 2D and 3D sipe design on the tread blocks improves snow performance while ensuring the rigidity of the tread blocks, avoiding insufficient grip due to weak rigidity, tread block breakage, and cracks caused by excessive heat generation. Reinforcing ribs connect the tread blocks to improve their rigidity. The β-design of the groove walls and the application of sipes increase the tread flexibility and stress on the tread blocks, reducing heat generation. The groove bottoms are equipped with a self-cleaning device to effectively prevent stones from getting stuck in the groove bottoms and causing cracks.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
