Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the side structure of a tire, in particular to a side structure of a tire. BACKGROUND

[0002] As a key component of a vehicle in contact with the ground, the side of a tire plays a vital role. The side of a tire generally refers to the area between the tire bead and the tire shoulder, which not only bears lateral force, bending stress and other complex external forces during vehicle driving, but also protects the internal structure of the tire, such as the cord layer, from damage from the outside world. At the same time, the appearance design of the tire side also affects the overall aesthetics and brand recognition of the tire to some extent.

[0003] In the traditional design of the side structure of a tire, the surface of the side of most tires is relatively smooth and flat, or only has simple textures and markings. This traditional side structure has some obvious drawbacks. On the one hand, from a functional point of view, the smooth side of the tire has relatively small friction between the tire and the ground during vehicle driving, especially in bad road conditions such as wet, muddy or icy conditions, which can easily lead to a decrease in vehicle handling performance, such as longer braking distance and poor steering stability, which poses a potential threat to road safety. On the other hand, from the perspective of appearance design and brand marketing, the traditional tire side lacks unique visual effects and personalized features, making it difficult to stand out in the market among numerous tire products, which is not conducive to tire manufacturers establishing a unique brand image and improving the market competitiveness of their products. In addition, with the continuous development of the automotive industry and the increasing demand of consumers for vehicle performance and appearance, the traditional tire side structure has been difficult to meet the needs of modern vehicles for diversified performance and aesthetics of tires, so it is of great practical significance to develop an innovative tire side structure. SUMMARY

[0004] Therefore, the utility model provides a side structure of a tire, which solves the drawbacks of monotonous design and single knurling line type of the side of a traditional tire.

[0005] The utility model is implemented as follows:

[0006] The utility model provides a side structure of a tire, which comprises a tire, a plurality of knurling lines are designed on the side of the tire, the knurling lines are formed on the sidewall of the tire by a knurling engraving process; the knurling lines are composed of sparse knurling lines and dense knurling lines, the sparse knurling lines and the dense knurling lines are alternately arranged on the side of the tire; the knurling lines are composed of arrayed laser line type protrusions, the knurling lines and the tire are integrally formed;

[0007] The sparse knurl lines are arranged in an X shape in a radial manner, and the dense knurl lines are arranged in a diamond shape in a horizontal line or a vertical line.

[0009] On the basis of the above technical scheme, the tire side structure of the utility model can be further improved as follows:

[0010] The sparse knurl lines are composed of a plurality of parallel knurl lines and form a non-closed polygon pattern.

[0011] The beneficial effects of the above improvement scheme are as follows: the polygon pattern formed by the dense knurl lines is a closed geometric polygon, so that the stress can be more evenly distributed on each side and vertex of the polygon when the tire is stressed, thereby effectively improving the overall structural strength of the tire.

[0012] Further, the dense knurl lines are composed of a plurality of parallel knurl lines and form a non-closed polygon pattern.

[0013] Further, the sparse knurl lines and the dense knurl lines are connected and combined into a new polygon pattern on the tire side.

[0014] Further, the design angle of the sparse knurl lines and the dense knurl lines is 0-90°, and the design angle is specifically an angle between the knurl lines and the tire side wall.

[0015] Further, the spacing between the sparse knurl lines is 0.6-1.2 mm, and the spacing between the dense knurl lines is 0.5-0.8 mm.

[0022] The tire will generate a large amount of heat during high-speed driving, especially in the tire side part, because it is constantly subjected to bending and tensile deformation, the heat accumulation is more obvious. The knurling line structure of the utility model increases the surface area of the tire side, so that the tire can dissipate heat more effectively when in contact with air. Heat can be dissipated more quickly through the air gap between the knurling lines and the convection of the laser line type protrusions and air, thereby reducing the temperature inside the tire, reducing the problems of tire material aging, performance degradation and the like caused by high temperature, prolonging the service life of the tire, and improving the reliability and safety of the tire in high temperature environment;

[0023] (II) improving the appearance design and brand recognition of the tire:

[0024] The polygonal laser line pattern composed of sparse knurling lines and dense knurling lines forms a unique and novel visual effect on the tire side, which is in sharp contrast with the monotonous appearance of the traditional tire side.

[0025] (III) advantages brought by the one-piece forming process:

[0026] The polygonal knurling line and the tire are formed by one-piece forming process, which ensures the connection strength and stability between the knurling line and the main body of the tire. Compared with the traditional post-processing or additional decorative parts, one-piece forming avoids the risk of tire failure caused by loose or falling connection parts. At the same time, the one-piece forming process can simplify the production process, improve the production efficiency and reduce the production cost, so that the tire of the utility model has better cost performance advantage in the market.

[0059] Specifically, the principle of the utility model is:

[0060] (I) Knurling carving process principle:

[0061] The knurling carving process is a key technology for forming knurling lines on the sidewall surface of the tire. In the knurling carving process, a specific knurling tool is used, and the tool has a tooth shape or pattern matching the shape of the required knurling lines. When the tool is in contact with the sidewall surface of the tire at a certain pressure and rotation speed and moves relatively, a series of laser line protrusions are formed on the rubber surface of the tire through the extrusion and cutting action of the tool, and these protrusions are arranged according to the predetermined pattern, i.e., the sparse knurling lines and the dense knurling lines are formed;

[0062] (II) Mechanical principle of polygonal pattern:

[0063] The polygonal pattern composed of sparse knurl lines and dense knurl lines plays an important role in the mechanical properties of the tire. The structural characteristics of the polygon make the tire better disperse stress and avoid stress concentration in a certain point or area when subjected to lateral force and bending force, thereby improving the overall strength and fatigue resistance of the tire. For example, when the vehicle is turning, the polygonal laser line pattern on the tire side can effectively resist the action of lateral force, reduce the deformation and wear of the tire, and maintain the stable operation of the tire;

[0064] (Three) Material combination principle of one-piece molding:

[0065] The one-piece molding of the polygonal knurl line and the tire is realized through the vulcanization process. During the vulcanization process, the rubber material of the tire undergoes chemical reaction under high temperature and high pressure, forming cross-linked structure between molecular chains, thereby making the rubber material have better strength, elasticity and wear resistance, etc. At the same time, the rubber material of the knurl line part is also closely combined with the rubber material of the main body of the tire in the vulcanization process, forming an organic whole. This one-piece molding structure greatly enhances the bonding force between the knurl line and the tire, avoiding the risk of knurl line falling off or damage caused by external factors, ensuring the reliability and stability of the tire in the long-term use process.
