Description

Technical Field

[0001] The utility model relates to the technical field of off-road vehicle tires, in particular to an off-road tire with a pangolin-shaped pattern structure. Background Art

[0002] Off-road tires are specially designed for off-roading. The sidewall design is harder, the tire teeth are more exaggerated, and the distance between the tire teeth is significantly larger, which is convenient for slow mud discharge or high-speed mud dumping when driving on muddy ground. In addition, it is easier to increase adhesion on some harsh ground (such as uneven rocky roads). When driving on muddy ground, the silt in the gaps between the tire treads can be quickly removed, making it easy to drive on mountain roads and muddy roads. The tread structure uses an increased groove volume ratio to increase the tire's tolerance to mud and sand, thereby improving traction performance. In addition, off-road enthusiasts will also make a fuss about tire pressure. By reducing tire pressure, the off-road performance of the vehicle is improved, and the damage to the body and vehicle caused by bumps is reduced, thereby increasing driving comfort.

[0003] The existing off-road tire pattern design is rough, the tread gap is large, and the increase in the tread groove area in the tread pattern causes the performance on paved roads to decrease, the noise to increase, and the rolling resistance and fuel consumption to increase. When driving off-road tires, most people choose to reduce the tire pressure to improve the traction performance of the tire, which can easily cause the pattern blocks to tear and collapse, so it is necessary to pay attention to improving the rigidity of the pattern blocks when designing the pattern.

[0004] Based on this, a pangolin-shaped pattern structure off-road tire is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0005] The utility model aims to provide an off-road tire with a pangolin-shaped pattern structure to solve the problems of rough pattern design, large tread gap, increased tread groove area in the tread pattern, decreased paved road performance, increased noise, increased rolling resistance and fuel consumption in the existing off-road tires. During the driving of the off-road tires, most people choose to reduce the tire pressure to improve the traction performance of the tires, which easily causes the problem of tearing and breaking of pattern blocks.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pangolin-type off-road tire comprises a middle pattern block and a shoulder pattern block. The tire tread structure is divided into two parts, namely, the middle pattern block and the shoulder pattern block. The middle pattern block comprises two groups of first pattern blocks and second pattern blocks. The shoulder pattern blocks comprise two long pattern blocks and a short pattern block of different lengths. The long pattern blocks and the short pattern blocks are alternately arranged in the circumferential direction of the tire. The long pattern blocks correspond to the second pattern blocks, and the short pattern blocks correspond to the first pattern blocks.

[0008] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:

[0009] In an optional solution: the middle pattern block has a pangolin pattern structure, and the pangolin pattern blocks are anti-symmetrically distributed and staggered with the pattern blocks to form a large middle pattern block.

[0010] In an optional solution, the central groove of the middle pattern block is formed into an S-letter pipe by two groups of middle pattern block edges.

[0011] In an optional solution: the first long strip ribs and the second long strip ribs are regularly arranged at the groove bottom of the shoulder pattern block.

[0012] In an optional solution: adjacent edges of the first pattern block and the second pattern block engage with each other to form a mortise and tenon structure.

[0013] In an optional scheme: the pangolin-like pattern structure is an antisymmetric pangolin design, the angle a° between the side lengths L1 and L2 of the pangolin-like pattern structure is an obtuse angle, and the angle range is defined in the interval of 124°-141°, the angle b° between the side lengths L2 and L3 is an acute angle, and the angle range is defined in the interval of 38°-48°, the angle c° between the side lengths L1 and L4 is an obtuse angle, and the angle range is defined in the interval of 115°-137°, and the length range is determined according to the angles a°, b°, and c° on both sides, thereby forming a pangolin-like pattern structure.

[0014] In an optional solution: the mortise and tenon structure is formed with a connection area in two transverse directions L3 and L5 and a longitudinal direction L6, and the length variation principle determines that L3>L5>L6.

[0015] In an optional solution: the S-shaped pipe 7 is formed by connecting the edges of two groups of pattern blocks A, and the edge angles d°, e°, f°, and h° are all obtuse angles, and the angle range is defined in the range of 128°-163°.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] The utility model can reduce the pump noise generated by the volume of the pattern groove through the angle design of the S-letter pipe. The mortise and tenon structure connects the two pattern blocks together to improve the rigidity of the pattern blocks in the circumferential direction, reduce the phenomenon of pattern block tearing and collapse, improve performance, reduce noise and rolling resistance, and reduce fuel consumption.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] In one embodiment, Figure 1-Figure 3 As shown, an off-road tire with a pangolin-type pattern structure includes a middle pattern block A and a shoulder pattern block B. The tire tread structure is divided into two parts, the middle pattern block A and the shoulder pattern block B. The middle pattern block A is composed of two groups of first pattern blocks 1 and second pattern blocks 2, and the shoulder pattern block B is composed of two long pattern blocks 3 and short pattern blocks 4 of different lengths, and the long pattern blocks 3 and the short pattern blocks 4 are alternately arranged in the circumferential direction of the tire, the long pattern blocks 3 correspond to the second pattern blocks 2, and the short pattern blocks 4 correspond to the first pattern blocks 1, which can improve the circumferential rigidity of the pattern blocks, improve performance, and reduce noise.

[0024] In one embodiment, Figure 1 As shown, the middle pattern block A has a pangolin-like pattern structure, and the pangolin pattern blocks are anti-symmetrically distributed and staggered with the pattern blocks 2 to form a large middle pattern block A.

[0025] In one embodiment, Figure 1 As shown, the central groove of the middle pattern block A is formed by two groups of middle pattern block edges to form an S-shaped pipe 7. The angle design of the S-shaped pipe 7 can block the inlet and outlet speed of the airflow when the tire is running in the circumferential direction, thereby reducing the pumping noise of the pattern groove.

[0026] In one embodiment, Figure 1 As shown, the first long strip ribs 5 and the second long strip ribs 6 are regularly arranged at the groove bottom of the shoulder pattern block B, which has the effect of repelling stones.

[0027] In one embodiment, Figure 1 As shown, the adjacent edges of the first pattern block 1 and the second pattern block 2 engage with each other to form a mortise and tenon structure 8. When the tire is running in the circumferential direction, the two connected pattern blocks are connected together to improve the circumferential rigidity of the pattern blocks and reduce the phenomenon of pattern block tearing and breaking.

[0028] In one embodiment, Figure 2 and Figure 3 As shown, the pangolin-style pattern structure is an antisymmetric pangolin design. The angle a° between the side lengths L1 and L2 of the pangolin-style pattern structure is an obtuse angle, and the angle range is defined in the interval of 124°-141°. The angle b° between the side lengths L2 and L3 is an acute angle, and the angle range is defined in the interval of 38°-48°. The angle c° between the side lengths L1 and L4 is an obtuse angle, and the angle range is defined in the interval of 115°-137°. The length range is determined according to the angles a°, b°, and c° on both sides, thereby forming a pangolin-style pattern structure.

[0029] In one embodiment, Figure 2 and Figure 3 As shown, the mortise and tenon structure is formed by two lateral directions L3 and L5 and one longitudinal direction L6 to form a connection area. The length change principle determines that L3>L5>L6. When the tire rolls circumferentially, the long side L3 and the short side L5 are automatically locked, thereby enhancing the circumferential rigidity of the pattern block.

[0030] In one embodiment, Figure 2 and Figure 3 As shown, the S-letter duct 7 is composed of the edges of two groups of middle pattern blocks A, and the edge angles d°, e°, f°, and h° are all obtuse angles. The angle range is defined in the range of 128°-163°. Reasonable angle parameter design can block the inlet and outlet speed of the airflow when the tire is traveling in the circumferential direction, and reduce the pump noise of the pattern groove.

[0031] The above embodiment discloses an off-road tire with a pangolin-shaped pattern structure. When the tire is running, the groove pumping noise generated by the squeezing, sliding, and friction between the pattern and the ground is reduced. The angle design of the S-letter pipe can reduce the pumping noise generated by the volume of the pattern groove. The groove between two adjacent pattern blocks forms a mortise and tenon structure 8 when the tire is running in the circumferential direction. The mortise and tenon structure 8 connects the two pattern blocks together to improve the circumferential rigidity of the pattern blocks and reduce the phenomenon of pattern block tearing and collapse. Even when the off-road tire is running at low air pressure, the rigidity of the off-road tire in the circumferential direction can still be maintained.

[0032] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
