Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, specifically to an intelligent tire structure. Background Technology
[0002] As a crucial component of automotive intelligence, smart tires rely on sensors for real-time monitoring of tire conditions. Current smart tire sensor embedding technologies primarily fall into two categories: adhesive bonding and integrated vulcanization. Adhesive bonding uses adhesives to fix the sensor to the inner surface of the tire. To ensure adhesion, the inner tire surface needs to be sanded to remove the oil film. While this process is relatively simple, the sanding process easily damages the tire's airtight layer, leading to a decrease in tire air retention. Furthermore, since the sensor is only bonded on one side, with the other sides exposed, the sensor's lifespan is significantly shortened when harmful liquids or gases seep into the inner tire surface.
[0003] Integrated vulcanization technology embeds sensors during tire blank forming and then vulcanizes them together with the tire blank, aiming to achieve integration between the tire and the sensor. While this method can ensure the structural integrity of the tire to a certain extent, tire vulcanization requires a long period of high temperature (usually above 150°C) and high pressure (5-10MPa) environment. Since sensors are mostly composed of electronic components that are not resistant to high temperature and high pressure, they are prone to material deformation and structural damage during the vulcanization process, resulting in low sensor survival rate. This seriously affects the production efficiency and performance stability of smart tires. Therefore, a smart tire structure is proposed. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides an intelligent tire structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent tire structure, comprising:
[0006] The tire body has a reserved groove on one side of its inner wall, and the reserved groove is integrally formed with the tire body. A sensor is installed inside the reserved groove. Pins are provided at both the upper and lower ends of the sensor. First adhesive is provided on both the front and rear sides of the sensor inside the reserved groove.
[0007] Preferably, the interior of the tire body is provided with four protrusions evenly distributed along a ring, and the protrusions are integrally formed with the tire body, and the protrusions play a positioning role.
[0008] Preferably, the outer surface of the bump is provided with a textured surface, and the textured surface is integrally formed with the bump. The textured surface is a sulfurized etched textured surface, which increases the contact area of the second adhesive.
[0009] Preferably, a second adhesive is disposed on the outside of the textured surface, and a sound-absorbing cotton is disposed on the outside of the second adhesive. The second adhesive is a neoprene rubber adhesive.
[0010] Preferably, the outer side of the tire body is provided with equally spaced drainage grooves along a circumference, the drainage grooves are integrally formed with the tire body, and the drainage grooves are used for drainage.
[0011] Preferably, the outer edge of the tire body is provided with side grooves that are equidistantly distributed along the annular ring, and the side grooves are integrally formed with the tire body. The side grooves are connected to the drainage grooves and are used to extend the drainage grooves to improve the drainage effect.
[0012] Compared with the prior art, the present invention provides an intelligent tire structure with the following advantages:
[0013] This invention achieves non-destructive embedding of the sensor within the tire body by pre-setting a groove and using a first adhesive. This design avoids material deformation and structural damage to the sensor caused by the high-temperature and high-pressure vulcanization environment, significantly improving the sensor's survival rate and operational reliability. At the same time, it eliminates the need for grinding the inner wall of the tire. The positioning and bonding of the pre-set groove and the first adhesive avoid the risks of airtight layer damage and sensor exposure and damage in adhesive-based technologies, ensuring tire air retention and sensor lifespan.
