Description

Technical Field

[0001] This utility model belongs to the field of tire technology, and more specifically, relates to a tire tread pattern and an all-weather low-noise tire. Background Technology

[0002] As a key component that directly contacts the ground, tires play a crucial role in vehicle safety, handling stability, and ride comfort. Under varying road conditions and weather environments, tires need diverse performance characteristics to meet the normal driving needs of vehicles. For example, on wet roads, tires need good water drainage to prevent hydroplaning and ensure stable braking and steering; on dry roads, tires need sufficient grip and handling to allow the vehicle to move precisely according to the driver's intentions; simultaneously, to enhance the passenger experience, tires also need to have low noise levels. Therefore, developing a tire that can balance water drainage, handling, and quietness under all weather conditions is of significant practical importance.

[0003] Currently, tire products on the market primarily focus on improving one or a few performance aspects in their design. Regarding water drainage, some tires achieve this by incorporating longitudinal grooves in the tread. These grooves quickly expel water from the tire's contact patch, reducing the impact of water accumulation on tire grip. However, this design, relying solely on grooves for drainage, has limitations in drainage efficiency and path optimization. In cases of heavy rainfall or deep water, drainage may still be insufficient, leading to hydroplaning.

[0004] In terms of handling performance, some tires enhance traction by adjusting the shape and layout of their tread blocks. For example, the tread blocks are designed with specific geometries to generate greater friction upon contact with the ground. However, these designs often overlook the mechanical balance of the tread blocks under stress. When cornering or making emergency maneuvers, the tire may experience insufficient lateral support, affecting the vehicle's handling stability.

[0005] In terms of noise reduction, existing tire noise reduction technologies mainly focus on adding sound-absorbing materials to the tire cavity, using the porous structure of these materials to absorb noise generated during tire operation. However, this single cavity-based noise reduction method has limited effectiveness in suppressing aerodynamic noise and structural vibration noise generated when the tire contacts the ground, and the quietness inside the vehicle still needs further improvement.

[0006] In summary, current tire technology struggles to simultaneously meet the high demands for drainage, handling, and quietness under all-weather conditions. On wet roads, insufficient drainage efficiency can lead to hydroplaning, affecting driving safety. Regarding handling, imperfect tread block mechanical balance design can worsen vehicle stability. As for noise reduction, single noise reduction methods are insufficient to effectively reduce various types of noise, impacting passenger comfort. Therefore, there is a need to develop a new tire tread pattern and an all-weather low-noise tire to address these issues in existing technologies and achieve a comprehensive improvement in drainage, handling, and quietness on both dry and wet roads.

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tire tread pattern and an all-weather low-noise tire.

[0008] To achieve the aforementioned utility model objective, the technical solution adopted by this utility model includes: a longitudinally arranged main groove is formed on the tire tread, located in the middle of the lateral direction of the tire tread; a water-guiding block is fixedly connected within the main groove; longitudinally arranged auxiliary grooves are formed on both sides of the main groove, parallel to the main groove; multiple tread blocks are arranged between the auxiliary grooves and the main groove; side blocks are arranged on the auxiliary grooves away from the main groove; multiple shoulder grooves are formed on the side blocks along the longitudinal direction; a shock-absorbing layer and sound-absorbing cotton are provided in the inner cavity of the tire; multiple tread blocks are arranged in a longitudinal array; the side of the tread block closest to the auxiliary groove is in the same direction as the auxiliary groove, and the side closest to the main groove is in the same direction as the main groove; the two ends of the tread block are inclined at an angle of 45°. Optionally, the height of the water guide blocks is lower than the depth of the main trench, and the water guide blocks are arranged in an array along the longitudinal direction.

[0009] Optionally, the depth of the auxiliary ditch may be less than the depth of the main ditch.

[0011] Optionally, the shoulder groove is located on both sides of the tire width. The shoulder groove follows the curvature of the tire, and the groove depth gradually decreases in the direction away from the main groove. The groove opening of the shoulder groove corresponds to the groove of the two tread blocks. The end of the shoulder groove away from the tread block is inclined, and the inclination direction of the shoulder groove is the same as the inclination direction of the end of the tread block.

[0013] Compared with the prior art, the advantages of this utility model include: This utility model provides a tire tread pattern and an all-weather low-noise tire. This tire effectively improves drainage performance by incorporating main grooves, secondary grooves, water guide blocks, tread blocks, and shoulder grooves on the tread. The main grooves are located in the transverse center of the tread and, together with the water guide blocks, quickly guide water flow. The secondary grooves are parallel to the main grooves and distributed on both sides, further dispersing the water flow. The shoulder grooves are located on both sides of the tire, with gradually decreasing depth, facilitating the guidance of water to the outer side of the tire, reducing hydroplaning, and enhancing the tire's grip and driving safety on wet and slippery roads.

The shock-absorbing layer can effectively buffer the vibration during driving. The auxiliary cotton and the sound-absorbing cotton are made of the same material and are molded together. The sound-absorbing cotton completely wraps the shock-absorbing layer and is thicker, which can efficiently absorb the noise generated by the rolling of the tire, creating a quieter and more comfortable driving environment for the driver and passengers and improving the driving experience.

[0023] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0024] Example 1 Please see Figure 1 and Figure 2 A tire pattern and all-weather low-noise tire includes a tread 1, on which a main groove 11 is formed. The main groove 11 is arranged longitudinally, which is the circumferential direction of the tire, and the transverse direction is the width direction of the tire. The main groove 11 is located in the middle of the transverse direction of the tread 1. Water guide blocks 12 are fixedly connected in the main groove 11. The height of the water guide blocks 12 is lower than the groove depth of the main groove 11. The water guide blocks 12 are arranged in an array along the longitudinal direction.

[0025] Please see Figure 1 and Figure 2 Auxiliary ditches 2 are provided on both sides of the main ditch 11. The auxiliary ditches 2 are parallel to the main ditch 11 and are arranged longitudinally. Multiple patterned blocks 3 are provided between the auxiliary ditches 2 and the longitudinal main ditch 11. The multiple patterned blocks 3 are arranged in an array along the longitudinal direction. The side of the patterned block 3 closest to the auxiliary ditch 2 is in the same direction as the opening of the auxiliary ditch 2, and the side of the patterned block 3 closest to the main ditch 11 is in the same direction as the opening of the main ditch 11. The two ends of the patterned block 3 are inclined. The ends of the patterned block 3 are inclined towards the auxiliary ditch 2 from the side closest to the main ditch 11, with an inclination angle of 45°. The depth of the auxiliary ditch 2 is less than the depth of the main ditch 11. Please see Figure 1 and Figure 2 The water guide blocks 12 in the main channel 11 are set at one end of each patterned block 3. The inclined direction of the water guide blocks 12 is the same as the inclined direction of the end of the patterned block 3. Adjacent water guide blocks 12 are symmetrically arranged in the longitudinal direction. Please see Figure 1 and Figure 2A side block 4 is provided on the auxiliary groove 2 away from the main groove 11. The side block 4 is located on the side of the auxiliary groove 2 away from the main groove 11. Multiple shoulder grooves 41 are opened on the side block along the longitudinal direction. The shoulder grooves 41 are located on both sides of the tire width. The depth of the shoulder grooves 41 gradually decreases as it moves away from the main groove 11 along the curvature of the tire. The groove opening of the shoulder groove 41 corresponds to the groove of the two tread blocks 3. The end of the shoulder groove 41 away from the tread block 3 is inclined. The inclination direction of the shoulder groove 41 is the same as the inclination direction of the end of the tread block 3.

[0026] Please see Figure 1 and Figure 2 The inner cavity of the tire is provided with a shock-absorbing layer 5 and a sound-absorbing cotton 6. Auxiliary cotton 61 is provided at both ends of the shock-absorbing layer 5. The auxiliary cotton 61 and the sound-absorbing cotton 6 are made of the same material and are molded together. The sound-absorbing cotton 6 can completely wrap the shock-absorbing layer 5. The thickness of the sound-absorbing cotton 6 is greater than the thickness of the auxiliary cotton 61.

[0027] The advantages of this invention are as follows: The tire tread pattern and all-weather low-noise tire demonstrate significant advantages in actual use. The coordinated design of the main groove 11 and auxiliary groove 2 on the tread 1, along with the precise layout of the water guide block 12, significantly improves the tire's drainage efficiency when driving on wet and slippery roads. The water guide block 12 and the tread block 3 have the same tilt direction at their ends, effectively guiding water flow quickly through the main groove 11, avoiding water accumulation and reducing hydroplaning. At the same time, the depth difference design between the main groove 11 and the auxiliary groove 2 further optimizes the drainage path, ensuring stable tire grip.

[0028] The 45° inclined structure at the end of tread block 3 and the arc design of shoulder groove 41 form a dynamic mechanical balance. When the tire contacts the ground, the inclined surface at the end of tread block 3 and the inclined surface of shoulder groove 41 are subjected to force simultaneously, converting vertical pressure into lateral dispersion force. This not only enhances the friction coefficient between the tire and the road surface, but also buffers the impact force through the gradual depth design of shoulder groove 41, significantly improving the lateral support force when the vehicle is cornering and noticeably improving handling stability.

[0029] The vibration-damping layer 5 and the sound-absorbing cotton 6 in the tire's inner cavity form a triple noise reduction system. The vibration-damping layer 5 absorbs low-frequency vibrations generated by road impacts, the sound-absorbing cotton 6 absorbs mid-to-high-frequency noise through its porous structure, and the auxiliary cotton 61 fills the gaps at the edges of the vibration-damping layer 5, forming a complete acoustic barrier. This layered design effectively blocks the noise generated by the tire during driving, significantly improving the quietness of the vehicle interior, making it especially suitable for driving scenarios with frequent starts and stops in urban areas.

[0030] The corresponding design of the shoulder groove 41 and the groove of the tread block 3 forms an airflow channel when the tire rolls. When the tire rotates, air flows orderly through the channel formed by the shoulder groove 41 and the groove of the tread block 3, reducing aerodynamic noise caused by air stagnation on the tread 1, while optimizing the airflow distribution on the tire surface, reducing the drag coefficient, and further improving fuel economy.

[0031] This tire achieves comprehensive improvements in drainage, handling, and quietness through structural innovation, maintaining stable performance on both dry and wet roads, and significantly enhancing its all-weather applicability.

[0032] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model.
