Description

Technical Field

[0001] The present invention relates to the technical field of vehicle tires, and more particularly to a sports-type green and environmentally friendly tire pattern structure and a tread grinding and processing device thereof. Background Art

[0002] With the rapid development of the automotive industry, consumers' requirements for vehicle performance are increasing. As the only component in contact with the ground, the performance of tires is crucial to the power and handling of sports cars. Traditional tires often cannot meet the vehicle's requirements for grip and traction, handling and stability, drainage capacity and rolling resistance, as well as response speed when driving at high speeds and under intense control. Therefore, the development of ultra-high performance tires has become an inevitable trend to adapt to the ever-increasing performance of vehicles.

[0003] At the same time, with the gradual enhancement of environmental awareness, global attention to environmental protection continues to rise. Tire rolling resistance is closely related to vehicle fuel consumption. Reducing tire rolling resistance can effectively reduce vehicle fuel consumption and carbon dioxide emissions. This has prompted tire manufacturers to devote themselves to the research and development of green and environmentally friendly tires, using new materials and designs to minimize rolling resistance without sacrificing performance, achieve energy conservation and emission reduction, and meet the requirements of sustainable development.

[0004] However, the reduction of tire rolling resistance and the improvement of other performances are accompanied by the design of tire pattern structure and the tread grinding process after the pattern structure design. For example, the utility model patent CN209021833U discloses a tire tread grinding device, which uses a tensioning device to tighten and fix the tread, and automatically grinds various parts of the inner wall of the tread through the coordination of the tensioning device, the driving device and the grinding device;

[0005] However, the above patent content only has the function of grinding the tread on the outside of the tire. On the one hand, it is unable to grind the tread inside the tire, that is, it is unable to adapt to the removal of the edges of the internal tread of the tire. On the other hand, it is even more unable to remove the internal tread of the tire without destroying the existing pattern structure on the outside of the tire. There is also a lack of a structure for cleaning the internal tread of the tire and promoting its continuous operation. A solution is provided for this purpose. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Refer to the instruction manual Figure 1-Figure 7 , a sports green environmentally friendly tire pattern structure and tread grinding processing device thereof, such as Figure 1 and Figure 2 As shown, the tire body 01 includes an inner tread 02 provided inside the tire body 01, an arc scraping mechanism 03 and a pushing and supporting mechanism 04 provided on one side of the inner tread 02, and a pressing and supporting mechanism 05 provided on the top outer wall of the tire body 01;

[0036] like Figure 3 and Figure 4As shown, the arc scraping mechanism 03 includes a base 031 arranged at the bottom of the tire body 01, and a motor 032 is fixedly mounted on the outer wall of the base 031. The motor 032 is arranged in a horizontal state. A half gear 033 is provided on one side of the motor 032. The half gear 033 is arranged in a vertical state. The motor 032 on the base 031 drives the half gear 033 to rotate;

[0037] like Figure 3 and Figure 4 As shown, a double-toothed plate 034 is engaged at the top of the half gear 033, and the double-toothed plate 034 is slidably mounted on the outer wall of the base 031. A limit spring 035 is fixedly mounted on the outer wall of one side of the double-toothed plate 034, and the limit spring 035 is fixedly mounted on the outer wall of the base 031. Then, the half gear 033 periodically pushes the double-toothed plate 034 to slide to one side and pulls the limit spring 035, and when the double-toothed plate 034 is disengaged from the push of the half gear 033, it is pulled back into place by the limit spring 035.

[0038] like Figure 3 and Figure 4 As shown, the top of the double-toothed plate 034 is engaged with a gear 036, and the gear 036 is set in a vertical state. A rotating rod 037 is fixedly installed on the outer wall of one side of the gear 036. The rotating rod 037 is rotatably installed on the top of the base 031, and the rotating rod 037 is set in a horizontal state. The double-toothed plate 034 slides to drive the gear 036 to rotate, and then the gear 036 drives the rotating rod 037 to rotate.

[0039] like Figure 3 and Figure 4 As shown, a support plate 038 is fixedly installed on the outer wall of one side of the rotating rod 037, and the support plate 038 is set in a vertical state. A scraper 039 is fixedly installed on the top of the support plate 038, and the top of the scraper 039 is in contact with the inner tread 02. The rotation of the rotating rod 037 drives the support plate 038 to deflect the scraper 039.

[0040] like Figure 3 and Figure 5 As shown, a support frame 0310 is fixedly installed on the outer wall of one side of the base 031. The support frame 0310 is arranged in a V shape. Rotating rods 0311 are rotatably installed on both sides of the top of the support frame 0310. The two rotating rods 0311 are arranged symmetrically with each other. The tops of the two rotating rods 0311 fit into the inner tread 02. The support frame 0310 drives the rotating rods 0311 on both sides of the top to support the tire body 01.

[0041] like Figure 5 and Figure 6As shown, the push-support mechanism 04 includes a single pulley 041 fixedly mounted on the outer walls of the two rotating rods 0311, the two single pulleys 041 are staggered with each other, and the outer walls of the two single pulleys 041 are rotatably mounted with a synchronous belt 042, and the bottoms of the two synchronous belts 042 are jointly rotatably mounted with a double pulley 043, and the double pulley 043 is rotatably mounted on the top of the base 031, and the rotation of the double pulley 043 drives the two synchronous belts 042 to make the single pulleys 041 on both sides rotate synchronously, that is, the two single pulleys 041 drive the two rotating rods 0311 to rotate synchronously.

[0042] like Figure 5 and Figure 6 As shown, a ratchet 044 is fixedly installed on one side of the double pulley 043. The ratchet 044 is arranged in a vertical state. The ratchet 044 and the rotating rod 037 are arranged corresponding to each other. The rotation of the ratchet 044 can drive the double pulley 043 to rotate synchronously.

[0043] like Figure 5 and Figure 6 As shown, a pawl 045 is provided on the top of the ratchet 044, and the outer wall of the pawl 045 fits into the outer wall of the ratchet 044. A push plate 046 is rotatably installed on one side of the pawl 045, and the push plate 046 is fixedly installed on the outer wall of the rotating rod 037. The rotation of the rotating rod 037 drives the pawl 045 to deflect and push the ratchet 044 to rotate.

[0044] like Figure 7 As shown, the pressure support mechanism 05 includes a compression plate 051 slidably installed on the outer walls on both sides of the base 031, the two compression plates 051 are symmetrically arranged, the two compression plates 051 are arranged in a vertical state, and the tops of the two compression plates 051 are fixedly installed with pressure rods 052, the two pressure rods 052 are located at the top of the tire body 01, and the outer walls of the two pressure rods 052 are rotatably installed with pressure rollers 053, and the two pressure rollers 053 are symmetrically arranged.

[0045] like Figure 7 As shown, the outer walls of the two pressure rollers 053 fit together with the top of the tire body 01, and the bottom outer walls of the two compression plates 051 are fixedly installed with heavy pressure blocks 054. The gravity of the heavy pressure blocks 054 pulls the two compression plates 051 to drive the pressure rods 052 and pressure rollers 053 on both sides to move downward and fit and squeeze the top of the tire body 01.

[0046] During the specific implementation, the tire body 01 is first placed on top of the two rotating rollers 0311, that is, the inner tread 02 is in contact with the top of the two rotating rollers 0311, and the gravity of the weighted pressure block 054 pulls the two squeezing plates 051 to drive the pressure rods 052 and pressure rollers 053 on both sides to move downward and press the top of the tire body 01 to stabilize it;

[0047] The motor 032 on the start base 031 drives the half gear 033 to rotate, and then the half gear 033 periodically pushes the double-toothed plate 034 to slide to one side and pulls the limit spring 035. When the double-toothed plate 034 is released from the push of the half gear 033, the limit spring 035 pulls it back to its original position, and the double-toothed plate 034 slides back and forth left and right. The sliding of the double-toothed plate 034 drives the gear 036 to rotate, and the gear 036 drives the rotating rod 037 to rotate. The rotation of the rotating rod 037 drives the supporting plate 038 to deflect the scraper 039, and the scraper 039 deflects back and forth left and right to scrape and clean the debris and scraps on the surface of the inner tread 02.

[0048] At the same time, the rotating rod 037 rotates to drive the pawl 045 to deviate and push the ratchet 044 to rotate, that is, the reciprocating movement of the pawl 045 first pushes the ratchet 044 to rotate and then moves back and disengages from the ratchet 044, so that the ratchet 044 rotates intermittently. When the scraper 039 grinds the inner tread 02, the pawl 045 disengages from the ratchet 044, and when the scraper 039 moves back, the ratchet 044 is pushed to rotate by the pawl 045, and then the ratchet 044 drives the double pulley 043 to rotate synchronously.

[0049] The rotation of the double pulley 043 drives the two synchronous belts 042 to make the single pulleys 041 on both sides rotate synchronously, and the two single pulleys 041 can drive the two rotating rollers 0311 to rotate synchronously, so that the two rotating rollers 0311 jointly push the tire body 01 to move forward and rotate, making it easier for the scraper 039 to clean the rest of the inner tread 02, thereby achieving the effect of fully scraping the inner tread of the tire and being able to operate continuously.

[0050] To sum up, the present invention is based on two rotating rollers supporting the inner tread of the tire and stabilizing it, and then scraping the inner tread of the tire by a reciprocating scraper. At the same time, when the scraper moves back, it drives the two rotating rollers to rotate so that the tire rotates synchronously, thereby changing the position of the scraper on the inner tread of the tire, which is convenient for comprehensive scraping of the inner tread of the tire and continuous operation.

[0051] Refer to the instruction manual Figure 8 and Figure 9 The present invention also relates to a sports-type green and environmentally friendly tire pattern structure, including a central pattern block arranged on the tire body and shoulder pattern blocks on the left and right sides. A continuous central pattern block 1 is arranged in the center of the tread. The central pattern block 1 adopts a widened design and a continuous "arrow"-like shape design, which can improve the tire's handling stability and acceleration performance, and at the same time improve the overall stiffness of the pattern block, achieving perfect driving response accuracy and extraordinary handling performance.

[0052] like Figure 8As shown, a plurality of shoulder blocks 3 are arranged in an annular pattern on the left and right sides of the central pattern block 1. The left and right shoulder blocks 3 are staggered and adopt a large-pitch combination design to optimize the contact patch, improve the best ground contact force, maximize stability and wear resistance during cornering, and supplemented by fine sipes 11 to optimize water film penetration.

[0053] like Figure 8 As shown, a shoulder transverse pattern groove 5 is provided between two adjacent shoulder pattern blocks 3 located on the same side of the central pattern block 1 .

[0054] like Figure 8 As shown, a plurality of "E-shaped" crown blocks 2 are provided on both sides of the central block rib 1 in a circular distribution. The edge of the block wall of the crown block 2 is a multi-dimensional design with a large inclination angle. A small longitudinal groove 4 is provided on the crown block 2, and the groove is arranged on the crown block 2 facing the central block 1, and is connected to the front longitudinal groove 6 between the central block 1 and the crown block 2, thereby improving drainage.

[0055] like Figure 8 As shown, the crown block 2 is also provided with a fine knife groove 7, which passes through the longitudinal small groove 4. The fine knife groove 7 divides the crown block 2 into four small pattern blocks, which can optimize the water film penetration ability, reduce the water accumulation under a single pattern block, and shorten the wet braking distance.

[0056] like Figure 8 As shown, a rear longitudinal groove 9 is provided between the crown pattern block 2 and the shoulder pattern block 3 , and a transverse groove 10 is provided between the crown pattern block 2 and the crown pattern block 2 .

[0057] like Figure 8 As shown, the rear longitudinal grooves 9, the front longitudinal grooves 6, the transverse grooves 10, and the shoulder transverse pattern grooves 5 are coordinated, and the longitudinal grooves and the transverse grooves are designed to be interconnected, which can effectively ensure that the tire can quickly drain water when entering a flooded road surface, ensuring the tire's grip and traction on wet roads.

[0058] like Figure 8 As shown, the shoulder transverse pattern groove 5 adopts an open design, which improves the drainage performance, braking and handling performance. At the same time, the shoulder pattern block 3 is a large-pitch combination design, which can effectively improve the overall rigidity of the shoulder pattern block 3 and ensure accuracy when turning. At the same time, the pattern block is designed with a fine knife groove 11, which can effectively "shred" the noise area on the tread separately when the tire is running at high speed, reduce the spread of noise, and improve driving comfort.

[0059] like Figure 8As shown, the artistic font "SPORT-X" is designed at eight equally spaced points on the circumference of the central tread block 1 of the tire. The font is designed in an embedded manner, which not only implies the type of this tread from the semantic meaning, but also uses artistic font design, increasing the overall beauty of the tire.

[0060] As Figure 9 shown, the first region and the second region of the tread are arranged in a mirror image and staggered left and right. The misalignment distance is designed to be 30.1 mm, which can effectively optimize the overall performance of the tire, significantly enhance the performance of the tire in complex driving environments and road conditions, and at the same time is more sporty and fashionable, improving the overall visual effect of the vehicle.

[0061] As Figure 9 shown, the tread includes three pitch sizes of different sizes, namely the first pitch L1, the second pitch L2 and the third pitch L3. The pitch ratio of the tread is L1 < L2 < L3, and the pitch ratio is L1:L2:L3 = 1.0:(1.10 - 1.15):(1.20 - 1.25). The pitch ratio of the tread is an irrational ratio;

[0062] From the perspective of finite element analysis, when the pitch width is an irrational ratio, it is beneficial to reduce the probability of resonance, thereby reducing tire noise. The first pitch L1, the second pitch L2 and the third pitch L3 are arranged along the circumferential direction of the tire, and the large and small pitches are arranged staggeredly, further reducing the resonance ratio and improving the overall handling and comfort of the tire.

[0063] As Figure 8 and Figure 9 shown, the tread groove walls are designed with an inclined structure. The longitudinal tread grooves 9 and 6 have an inclination angle of 8 degrees, and their groove bottoms are designed with rounded corners; the transverse grooves 10 and 5 have an inclination angle of 5 degrees, and their groove bottoms are designed with arc shapes, which can effectively reduce the probability of the tire getting stuck with stones and other sundries during driving, and can effectively ensure the driving safety of the vehicle.

[0064] Compared with existing tires, the ultra-high performance sports green environmental protection tire of the present invention establishes a computer model to simulate the size and shape of the ground contact marks of the tire on dry flat, wet, gravel, mud, mountain curves, and rock slopes, the height and distribution of the ground contact pressure, and the contact conditions between the tread and gravel, mud, and rock slopes.

[0065] The best "arch-shaped" tread grooves, "S-shaped" tread grooves and "E-shaped" tread blocks, arrow-shaped tread blocks, knife-point-shaped tread blocks and strip-shaped tread blocks are designed, which greatly improve the passing rate of this tire on dry flat, wet, gravel, mud, mountain curves, and rock slope roads and functions such as drainage, mud discharge, and sand and gravel discharge, improve the stability and the improvement of the quick turning performance, and endow the tire with super strong grip and wear resistance;

[0066] For this purpose, we have developed an ultra-high-performance sports green and environmentally friendly tire formula: it has the advantages of safe braking, good elasticity, low rolling resistance, low fuel consumption, low heat generation, wear resistance, puncture resistance, large load capacity, and comfortable ride. Compared with traditional tires, it highlights the advantages of environmental protection, energy saving, new technology, new materials and other aspects.

[0067] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
