[0007] Furthermore, a distance H between the top of the linear structure and the bottom surface of the groove is 0.15 mm to 0.6 mm.

[0008] Furthermore, the cross-section of the linear structure is triangular or trapezoidal, and the vertex angle of the triangle or the angle X between the two oblique sides of the trapezoid is 45° to 50°.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In order to solve the problem of poor strength of patterns on tire sidewalls in the prior art, the utility model provides a tire and a tire mold thereof.

[0027] Example 1

[0028] like Figures 1 to 4 A tire shown includes: a tire body, the sidewall of the tire body having at least one groove 10, and a pattern unit 20 is arranged in the groove 10; wherein, the pattern unit 20 includes a plurality of linear structures 21 and a reinforcing line structure 22, the linear structure 21 is protruding relative to the bottom surface of the groove 10 and extending continuously along the sidewall surface, the linear structure 21 includes at least one of a straight line, a broken line, and an arc line, and the linear structures 21 are arranged at intervals, and the reinforcing line structure 22 is arranged in the interval and connected to the two adjacent linear structures 21 at both ends.

[0029] This embodiment utilizes a pattern unit 20 that utilizes a linear structure 21 and a reinforcing wire structure. The linear structure 21 extends continuously along the sidewall surface, forming a single, curved, and swirling linear structure. This ensures that the linear structures 21 within the same line are seamless and form a network-like structure. Furthermore, the reinforcing wire structure 22 fills the gaps between the linear structures 21, thereby compensating for the spaces between the linear structures. This arrangement enhances the strength of the tire pattern after vulcanization, while the dense lines create color variations on the tire pattern surface, improving tire quality. Furthermore, the specific orientation of the linear structure 21 creates a specific effect on the surface of the pattern unit 20. This addresses the current issue of monotonous and aesthetically pleasing tire sidewall patterns and improves tire exhaust efficiency during vulcanization.

[0030] In actual use, the specific form of the linear structure 21 can be selected according to needs, and can be a single straight line, a broken line, an arc, or a combination of multiple of the above three. Figure 1 As shown, this embodiment adopts a straight line plus a broken line structure, so that the linear structure 21 is formed into a broken line extending along a specific direction.

[0031] In this embodiment, the linear structures 21 have the same shape and are arranged parallel to each other. Specifically, the linear structures 21 that make up the pattern unit 20 are arranged parallel to each other. This allows bubbles generated during tire vulcanization to be promptly discharged along the middle of the two adjacent linear structures 21, thereby resolving quality issues such as poor tire tread performance caused by the inability to promptly discharge bubbles during vulcanization. Furthermore, the parallel arrangement of the linear structures 21 creates a more distinct and distinctive effect on the pattern surface, thereby resolving the current problem of monotonous and poorly aesthetically pleasing tire sidewall patterns. Of course, in addition to the aforementioned parallel arrangement, the linear structures 21 can also be arranged at a certain angle.

[0032] In this embodiment, multiple reinforcing wire structures 22 are provided, and multiple reinforcing wire structures 22 can be simultaneously provided between two adjacent linear structures 21. Reinforcing wire structures 22 within the same interval are spaced a certain distance apart along the extending direction of the interval, thereby satisfying the need for structural reinforcement at the interval. Furthermore, the reinforcing wire structures 22 within the same interval can be arranged in parallel or non-parallel, and the distances between reinforcing wire structures 22 within the same interval can be the same or different.

[0033] In this embodiment, a connection is formed between the reinforcing wire structure 22 and the linear structure 21, and the extension direction of the reinforcing wire structure 22 at the connection is arranged at an angle relative to the extension direction of the linear structure 21 at the connection. In other words, the extension direction of the reinforcing wire structure 22 is different from the extension direction of the linear structure 21 to which it is connected, thereby ensuring that the reinforcing wire structure 22 strengthens the linear structure 21. At the same time, because the linear structure 21 of this embodiment is in the form of a broken line, this embodiment arranges part of the connection at the bend of the linear structure 21, that is, the end of part of the reinforcing wire structure 22 is located at the bend of the linear structure 21, thereby reinforcing the position of the linear structure 21 that is most prone to deformation. Of course, in addition to arranging the connection at the bend, the end of other parts of the reinforcing wire structure 22 can also be arranged at the straight section of the linear structure 21. The specific position of the connection can be adjusted as needed.

[0034] This embodiment also optimizes the specific configuration parameters of the linear structure 21, thereby enabling the linear structure 21 to enhance structural strength while also making the formed pattern units 20 more distinct and aesthetically pleasing. Of course, the following parameters can be adjusted as needed and are not limited to the values ​​given in this embodiment.

[0035] like Figure 2 As shown, the cross section of the linear structure 21 of this embodiment, that is, the cross section perpendicular to the extension direction, is set to be trapezoidal, and the long side of the trapezoid is connected to the bottom surface of the groove 10. Of course, it can also be set to other shapes such as triangle.

[0036] like Figure 2 As shown, the height difference H between the top of the linear structure 21 and the bottom surface of the groove 10 in this embodiment is 0.15mm to 0.6mm. The setting of H allows the distance that the linear structure 21 protrudes from the bottom surface of the groove 10 to be controlled, ensuring the aesthetics of the pattern unit 20 formed by the linear structure 21.

[0037] At the same time, the angle X between the two hypotenuses of the trapezoid is 45° to 50°, so that the inclination of the hypotenuse of the trapezoid can adapt to the viewing angle of most observers, ensuring that the displayed pattern is clear and beautiful. When a triangular cross-section is used, the angle X is the vertex angle of the triangle.

[0038] The short side length E of the trapezoid in this embodiment, that is, the length of the side of the trapezoid facing the opening of the groove 10 or extending out of the opening of the groove 10, is 0.05mm to 0.08mm. This allows the short side of the trapezoid to create a certain visual effect.

[0039] like Figure 3 and Figure 4As shown, this embodiment adopts a configuration in which the linear structure 21 is entirely located within the groove 10. That is, along the depth direction of the groove 10, the top of the linear structure 21 is no higher than the upper edge surface of the groove 10, so that the linear structure 21 does not protrude from the groove 10. This ensures that the arrangement of the linear structure 21 does not affect the sidewall surface, avoiding the protrusion of the linear structure 21 affecting the performance of the sidewall, and ensuring that the sidewall functions normally. Preferably, the distance S between the top of the linear structure 21 and the upper edge surface of the groove 10 is 0 to 0.2 mm, ensuring that the linear structure 21 can be located within the groove 10 without protruding from the groove 10, while also ensuring a good visual effect.

[0040] like Figure 1 As shown, in this embodiment, the spacing B between two adjacent linear structures 21 is set to 0.45mm≤B≤0.6mm. When two parallel linear structures 21 are too close together, they can easily be mistaken for a single line, making them difficult to distinguish in terms of reflection and unable to produce different visual effects at different positions and distances. If the distance between the linear structures 21 is too large, the visual effect produced by the pattern unit 20 will be poor. Therefore, in this embodiment, the spacing B is set to 0.45mm≤B≤0.6mm. This not only ensures that the two adjacent linear structures 21 are not too close together, making them difficult to distinguish, but also solves the problem of the linear structures 21 of the pattern unit 20 being insufficiently dense, thereby ensuring the visual effect of the linear structures 21.

[0041] Optionally, the shape of the pattern unit 20 as a whole can also be set as needed, and can be set to a polygon such as a rectangle, a rhombus, etc. The pattern unit 20 of this embodiment adopts a rectangular shape as a whole, so as to facilitate processing and identification. At the same time, the pattern unit 20 has a first side and a second side adjacent to each other, and the length of the first side and / or the second side is greater than or equal to 21 mm. Figure 1 As shown, in this embodiment, the length C of the first side and the length D of the second side are both greater than or equal to 21 mm, so as to facilitate identification and marking.

[0042] This embodiment also provides a tire mold for manufacturing the above-mentioned tire, wherein the tire mold is provided with at least one raised module, the raised module is used to form the groove 10 of the tire, and the raised module is provided with multiple textures, the multiple textures are used to form the pattern unit 20 of the tire, so that the raised module corresponds to the required pattern unit 20, ensuring that the processed pattern unit 20 meets the requirements.

[0043] Example 2

[0044] The difference from the first embodiment is that the structure of the linear structure 21 is different.

[0045] like Figure 5As shown, in this embodiment, the linear structure 21 adopts an arc-shaped structure, and the reinforcing wire structure 22 is still arranged between two adjacent linear structures 21. The specific arrangement method can be basically the same as that in the first embodiment.

[0046] It should be noted that, in the above embodiments, a plurality refers to at least two.

[0047] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0048] 1. Solve the problem of poor pattern strength on the tire sidewall in the prior art;

[0049] 2. The strength of the tire pattern after vulcanization is higher, and the dense lines can make the tire pattern surface have color difference, thereby improving the tire quality;

[0050] 3. The specific directional arrangement of the linear structure can create a specific effect on the surface of the pattern unit, thereby solving the current problem of monotonous tire sidewall patterns and poor aesthetics, and promoting exhaust efficiency during tire vulcanization.
