Description

Technical Field

[0001] This application belongs to the field of electric vehicle parts technology, specifically relating to an anti-skid electric bicycle tire tread pattern. Background Technology

[0002] In existing technologies, to meet the strict weight restrictions imposed by the new national standard for electric bicycles, the weight of each component must be precisely controlled. After the new standard is implemented, manufacturers can no longer increase the range of electric bicycles by stacking batteries. Currently, manufacturers are improving the range of electric bicycles by reducing tire rolling resistance, thereby increasing the utilization rate of battery power.

[0003] In existing technologies, many tires reduce rolling resistance by increasing hardness and decreasing thickness. However, while reducing rolling resistance, this method also reduces the tire's energy absorption and support. When riding an electric vehicle, especially on complex road conditions or at high speeds, the vehicle is prone to skidding, seriously threatening riding safety. Furthermore, existing electric bicycle tire tread patterns have limitations in adapting to different road conditions. For example, some tires, in pursuit of low rolling resistance, adopt a slick tire-like tread design with fine surface patterns. While this can reduce energy consumption and increase speed on dry, flat roads, on wet, slippery surfaces, the lack of effective drainage patterns easily leads to the formation of a water film, preventing the tire from directly contacting the road surface and causing floating and slippage, greatly increasing the risk of sideslip. Some all-around tires use a semi-slick design on the front to ensure low rolling resistance, and the large rubber treads on the sides provide good grip when turning on rough or muddy roads. However, when turning on paved roads, the large rubber particles can cause excessive vibration and resistance, affecting riding comfort. Although urban tires effectively prevent hydroplaning through large-area drainage patterns and the continuous tread pattern reduces rolling resistance, their excessive emphasis on durability results in a heavy overall weight, which does not conform to the current trend of lightweight development for electric bicycles. Moreover, heavier tires can indirectly increase energy consumption and shorten the driving range.

[0004] Given the shortcomings of existing electric bicycle tire treads in terms of anti-skid performance, adaptability to different road conditions, and weight control, there is an urgent need to develop a new type of tire tread to improve the riding safety, comfort, and range of electric bicycles, and to meet the growing demand of consumers for high-quality travel. Utility Model Content

[0005] In order to address the technical problems in the prior art, where electric bicycles cannot stack batteries to improve their range due to the new national standard quality restrictions, and where manufacturers rely on increasing tire hardness and reducing tire thickness to reduce rolling resistance, but this easily leads to a decrease in tire support, making electric bicycles prone to sideslip during operation, and where existing tire tread patterns have poor adaptability to road conditions and are difficult to apply to complex road conditions, this application proposes an anti-slip electric bicycle tire tread pattern.

[0032] Combination Figures 1 to 11 The following description further illustrates the technical solution proposed in this application. This application adopts the following technical solution: an anti-skid electric bicycle tire tread pattern, comprising a first anti-skid group 1 disposed on one side of the tire tread, a second anti-skid group 2 disposed on the other side of the tire tread, a first support protrusion 3 disposed between the first anti-skid group 1 and the second anti-skid group 2, and a plurality of first grooves 4 disposed on the first support protrusion 3. The plurality of first grooves 4 are spaced apart along the rolling direction of the tire tread. Each first groove 4 includes a first arcuate groove 40 disposed on the first support protrusion 3, and a second arcuate groove 41 disposed on the first arcuate groove 40. The second arcuate groove 41 is inclined relative to the first arcuate groove 40, and the length of the second arcuate groove 41 is greater than the length of the first arcuate groove 40.

[0033] This application provides an anti-skid electric bicycle tire tread pattern, comprising a first anti-skid group on one side of the tread, a second anti-skid group on the other side, a first support protrusion between the two groups, and multiple first grooves on the support protrusion. The first grooves are spaced apart along the rolling direction and include a first arc-shaped groove and a second arc-shaped groove thereon. The second arc-shaped groove is inclined relative to the first arc-shaped groove and is longer. This application, through the combination of the first and second anti-skid groups on both sides and the central first support protrusion, reduces tire rolling resistance while enhancing tread support, effectively preventing tire skidding. By providing first grooves on the first support protrusion, the contact area between the tire and the ground is increased, allowing for rapid drainage of water and mud from the tread, improving wet grip, and effectively adapting to complex road conditions such as dry and wet surfaces. This application has the advantages of simple structure, good anti-skid effect, and ease of promotion and implementation.

[0034] In actual implementation, when an electric bicycle is in motion, the first anti-slip group 1 and the second anti-slip group 2 on both sides of the tire tread contact the ground to increase the friction of the tire tread edge and prevent the tire tread from shifting to the side when turning or tilting; the first support protrusion 3 in the middle is subjected to vertical force on the ground. With the increase in tire hardness and the reduction in thickness, it can make up for the defect of insufficient tire tread support, prevent the risk of sideslip caused by weak support during driving, and maintain low rolling resistance characteristics, which meets the new national standard for the quality restrictions of electric bicycles.

[0035] During the operation of the electric bicycle, multiple first grooves 4 are spaced apart along the rolling direction of the tire tread. When the tire tread contacts the ground, the first arc-shaped groove 40 can initially accommodate and guide the flow of accumulated water and mud. The second arc-shaped groove 41, which is inclined relative to the first arc-shaped groove 40 and is longer, can further expand the drainage path and accelerate the drainage speed, preventing water from forming a water film between the tire tread and the ground, and significantly improving the tire's wet grip. At the same time, the first groove structure makes the tire tread form an intermittent contact with the ground. On dry roads, the friction can be enhanced by the edge of the first groove, and on gravel roads, the groove can accommodate small gravel and reduce tire slippage.

[0036] In some feasible embodiments, the length of the second arcuate groove 41 is defined as L, and the length of the first arcuate groove 40 is defined as l, wherein L and l satisfy the following relationship: 2.5≤L / l≤3.5.

[0037] In some feasible embodiments, the first anti-skid group 1 includes a plurality of second grooves 10 provided on one side of the tread and a plurality of second support protrusions 11 provided on one side of the tread. The plurality of second grooves 10 are spaced apart along the rolling direction of the tread, and the second support protrusions 11 are provided between two adjacent second grooves 10.

[0038] In some feasible embodiments, the second groove 10 includes a second inclined groove 100 that is inclined relative to the centerline of the tread, a third arcuate groove 101 that is inclined on the second inclined groove 100, and a fourth arcuate groove 102 that is disposed between the second inclined groove 100 and the third arcuate groove 101.

[0039] In actual implementation, when an electric bicycle is in motion (especially when turning, tilting, or accelerating / decelerating), the first anti-slip group on one side of the tire tread directly contacts the ground. The second support protrusion between adjacent second grooves serves as the main force-bearing unit. Its raised structure increases the contact area between the tire tread and the ground, preventing the dispersion of contact force due to the increased tire hardness. At the same time, the spaced distribution of the second support protrusions forms an intermittent array of contact points. Each second support protrusion can independently generate frictional resistance with the ground. The frictional force of multiple second support protrusions is superimposed, significantly improving the grip of the tire edge, effectively suppressing the tendency of the tire tread to slide sideways during driving, and compensating for the insufficient edge support caused by the reduction in tire thickness.

[0040] On wet and slippery roads, water generated when the tire tread contacts the ground will quickly flow into the second groove. The extension path of the second groove along the rolling direction can guide the water to the rear or sides of the tire tread, preventing the water from forming a water film between the tire tread and the ground, and reducing the risk of tire slippage on wet surfaces. On complex road surfaces such as gravel and mud, the second groove can accommodate small gravel and mud from the road surface, preventing impurities from accumulating on the tire tread surface and causing a decrease in the coefficient of friction. This ensures that the second support bump can always form effective contact with the road surface, improving driving stability under different road conditions.

[0041] Furthermore, during driving, the tire tread will undergo slight deformation due to road bumps. When the second support protrusion is subjected to ground impact, the adjacent second groove allows the second support protrusion to undergo slight elastic deformation, preventing the second support protrusion from breaking or wearing due to excessive rigid stress. At the same time, the second groove structure can disperse the local stress of the tire tread, reduce fatigue damage caused by long-term concentrated stress on the tire tread, and extend the overall service life of the tire.

[0042] In some feasible embodiments, the angle of inclination of the second groove 100 relative to the centerline of the tread is defined as A, wherein A satisfies the following relationship: 45°≤A≤60°.

[0043] In some feasible embodiments, the arc-shaped region of the third arc-shaped groove 101 extends away from the second inclined groove 100, and the angle between the third arc-shaped groove 101 and the second inclined groove 100 is defined as B, wherein B satisfies the following relationship: 30°≤B≤50°.

[0044] In some feasible embodiments, a third support protrusion 5 is provided between the second inclined groove 100 and the third arc-shaped groove 101, and a third inclined groove 50 is provided on the third support protrusion 5, which is parallel to the second inclined groove 100.

[0045] In some feasible embodiments, the surface of the third support protrusion 5 is provided with a first support mesh 51.

[0046] In some feasible embodiments, a fifth arcuate groove 6 is also provided between two adjacent second grooves 10, and the second support protrusion 11 is provided in the enclosing area of ​​the two adjacent second grooves 10 and the fifth arcuate groove 6.

[0047] In some feasible embodiments, the surface of the second support protrusion 11 is provided with a fourth inclined groove 7, the fourth inclined groove 7 being parallel to the second inclined groove 100, and the surface of the second support protrusion 11 is provided with a second support mesh 8.

[0048] In actual implementation, the first and second anti-skid groups have the same structure, and the two are staggered on both sides of the tire tread.

[0049] This application provides an anti-skid electric bicycle tire tread pattern, comprising a first anti-skid group on one side of the tread, a second anti-skid group on the other side, a first support protrusion between the two groups, and multiple first grooves on the support protrusion. The first grooves are spaced apart along the rolling direction and include a first arc-shaped groove and a second arc-shaped groove thereon. The second arc-shaped groove is inclined relative to the first arc-shaped groove and is longer. This application, through the combination of the first and second anti-skid groups on both sides and the central first support protrusion, reduces tire rolling resistance while enhancing tread support, effectively preventing tire skidding. By providing first grooves on the first support protrusion, the contact area between the tire and the ground is increased, allowing for rapid drainage of water and mud from the tread, improving wet grip, and effectively adapting to complex road conditions such as dry and wet surfaces. This application has the advantages of simple structure, good anti-skid effect, and ease of promotion and implementation.
