Description

Technical Field

[0001] This utility model relates to the field of snow tire technology, specifically a snow tire with high snow removal performance. Background Technology

[0002] Snow tires are tires that, compared to regular tires, further improve handling and grip on icy and snowy roads in winter.

[0003] In Nordic regions such as Finland and northeastern my country, roads are often covered with ice and snow during winter. When tires are in motion, snow accumulates in the tread grooves and cannot be expelled in time. This causes snow to accumulate on the tire surface, reducing the friction between the tire and the road surface and causing slippage, which poses a significant threat to the safety of drivers and pedestrians.

[0004] An existing patent (authorization announcement number: CN221497557U) discloses a snow tire with an automatic snow removal device at the bottom of the groove. The key technical points of the solution are: by setting the tread grooves, multiple cuts are made on the tread blocks to reduce rigidity, thereby improving the snow tire's grip on icy and snowy roads. Under the action of the tread grooves, the snow accumulated in the tread grooves can be effectively discharged, reducing the accumulation of snow on the surface of the snow tire, thereby improving the snow tire's grip and handling performance and ensuring vehicle driving safety.

[0005] However, the above-mentioned technical solutions still have certain shortcomings. Existing snow tires mostly adopt a large-angle, herringbone-shaped tread pattern design, and the grooves are deeper than those of traditional summer tires. Multiple cuts are used on the tread blocks to reduce rigidity and improve the tire's grip on icy and snowy roads. However, current snow tire products on the market do not apply biomimetic principles to improve snow performance while also enhancing driving comfort. Therefore, a snow tire with high snow removal performance is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a snow tire with high snow removal performance to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A snow tire with high snow removal performance includes a rim, a tire shoulder fixedly mounted on the surface of the rim, and a tread disposed on one side of the tire shoulder. The tread is provided with grooves and a snow removal mechanism.

[0009] The tread features grooves designed with gecko-inspired groove technology to mimic the biological characteristics of a gecko when it attaches to its surface.

[0010] The bottom of the patterned grooves is equipped with snow spikes, and adjacent snow spikes are connected by interlocking bridges;

[0011] The tread shoulder is equipped with shoulder tread blocks designed with multiple staggered joints.

[0012] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0015] In one alternative snow tire with high snow removal performance: the tread grooves are configured as a first tread groove, a second tread groove, a third tread groove, a fourth tread groove, and a fifth tread groove.

[0016] In one snow tire option with high snow removal performance: the shape of the snow studs varies with the direction and width of the tread grooves, and each side is parallel to the wall of its adjacent tread groove.

[0017] In one snow tire option with high snow removal performance: the width (a) of the snow spike is 1 / 10 to 1 / 2 of the tread groove width (b), and the distance (c) between the two sides of the snow spike and the tread groove wall is equal.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, such as Figures 1-6 As shown, a snow tire with high snow removal performance includes a rim 1, a shoulder 2 fixedly mounted on the surface of the rim 1, and a tread 3 disposed on one side of the shoulder. The tread 3 has grooves and a snow removal mechanism 4. The snow removal mechanism 4 consists of a snow spike 41, an extension 43 fixedly mounted on the bottom of the snow spike 41, a stop 42 fixedly disposed on the inner wall of the tread 3, and a spring 44 wrapping the stop 42.

[0033] In this embodiment, the extension 43 lengthens the lever arm of the snow spike 41, generating a lever effect when the tire rolls, significantly enhancing the ability to break up compacted snow. The spring 44 ensures that the snow spike 41 always maintains effective contact with the snow, while avoiding structural damage caused by impacts from hard objects. The stop block 42 precisely limits the range of motion of the snow spike 41, preventing uneven wear caused by centrifugal force, extending the life of the components, and preventing the snow spike 41 from touching the tire tread 3 and causing tire damage.

[0034] In one embodiment, the tread 3 is provided with a patterned groove designed using gecko-inspired groove technology to simulate the biological characteristics of a gecko when it attaches to its surface; snow spikes 41 are provided at the bottom of the patterned grooves, and adjacent snow spikes 41 are connected by interlocking bridges 5; the shoulder of the tread 3 is provided with shoulder patterned blocks designed using multi-positional interlocking technology; the grooves adopt a unidirectional inclined design to form a "sticking-de-attachment" cycle similar to that of a gecko crawling; the surface of the grooves is provided with micron-level biomimetic protrusions to generate a capillary effect, disrupt the surface tension of snow water, the snow spikes 41 penetrate and compact the snow layer, the interlocking bridges 5 disperse the local load, and the grooves form vortices to accelerate snow removal.

[0035] In one embodiment, the snow spikes 41 are evenly distributed at the bottom of the circumferential tread grooves, with a number that is 3 to 10 times the number of tread pitches. The distance between each snow spike 41 on the same pitch is equal and they are evenly distributed. Through a high-density distribution that is 3 to 10 times the number of tread pitches, at least 2 to 3 effective snow spikes are maintained per square centimeter of tread 3. The even spacing forms a continuous breaking zone, eliminating snow removal blind spots. The equidistant distribution makes the centrifugal force evenly dispersed and avoids local stress concentration.

[0036] In one embodiment, the tread grooves on the tire tread 3 are configured as a first tread groove 31, a second tread groove 32, a third tread groove 33, a fourth tread groove 34, and a fifth tread groove 35. The shape of the snow spikes 41 varies with the direction and width of the tread grooves, and each side is parallel to the wall of its adjacent tread groove. The five sets of grooves form a hierarchical drainage network: the first / second grooves (main drainage) handle a large amount of snow melt, the third / fourth grooves (secondary drainage), and the fifth groove (micro-drainage) break the surface water film. The five sets of grooves generate sound waves of different frequencies, and the phase difference cancellation principle is used for synergistic noise reduction.

[0037] In one embodiment, the width (a) of the snow spike 41 is 1 / 10 to 1 / 2 of the width (b) of the tread groove, and the distance (c) between the two sides of the snow spike 41 and the tread groove wall is equal; the bottom of the circumferential tread groove is designed with special snow spikes 41 as an automatic snow removal device at the bottom of the groove, and the number is 3 to 10 times the number of tread pitches; the distance (d) between each snow spike 41 at the same pitch is equal and evenly distributed; each side of the snow spike 41 is parallel to the adjacent tread groove wall; the width (a) of the snow spike 41 is 1 / 10 to 1 / 2 of the tread groove (b), the distance (c) between the two sides of the snow spike 41 and the tread groove wall is equal, and the shape of each snow spike 41 changes with the direction of the tread groove, i.e., the change in width.

[0038] In one embodiment, the interlocking bridge 5 is a reinforcing structure that connects adjacent snow spikes 41 laterally. The interlocking bridge 5 connects adjacent snow spikes 41 into a whole, preventing individual snow spikes 41 from bending or breaking due to excessive force. When the tire rolls, the snow pressure is distributed to multiple snow spikes 41 through the interlocking bridge 5, reducing local stress concentration and extending service life. On bumpy or hard snow surfaces, the interlocking bridge 5 can absorb some of the impact and prevent the snow spikes 41 from breaking.

[0039] The above embodiment discloses a snow tire with high snow removal performance. The extension 43 lengthens the lever arm of the snow spike 41, generating a leverage effect when the tire rolls, which significantly enhances the ability to break up compacted snow. The spring 44 ensures that the snow spike 41 always maintains effective contact with the snow, while avoiding structural damage caused by impacts from hard objects. The groove adopts a unidirectional inclined design, forming an "adhesion-desorption" cycle similar to that of a gecko crawling. The groove surface is provided with micron-level biomimetic protrusions, which generate a capillary effect, disrupting the surface tension of snow water. The snow spike 41 penetrates the compacted snow layer, the interlocking bridge 5 disperses the local load, and the groove forms a vortex to accelerate snow removal.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
