Description

Tread pattern structure of children's scooter

Technical Field

The utility model relates to a technical field of tire especially indicates a use pneumatic tire tread decorative pattern structure on children's smooth step balance car.

Background

The children's sliding vehicle is mainly designed for infants, and needs to provide sliding power by continuously pedaling the ground with feet, exercise the balance ability of the infants and train limb reactions. With the continuous improvement of ' second-child new politics ' and domestic consumption level, domestic children's scooter has rapidly grown up in recent years, and training institutions and more professional scooter events are launched in a plurality of cities. Professional scooter competitions are usually held in indoor places, asphalt ways and light off-road roads, the indoor places and the asphalt ways are usually flat, tires selected are usually high land ratio and smooth tread patterns for speed increasing, and the light off-road roads are high and low undulating soil slope pump roads, and the matched tires are mainly granular patterns so as to seek superior ground gripping and sideslip prevention performance.

The existing common scooter for children has single tire performance, high land ratio and smooth tread patterns can reduce the rolling resistance lifting speed, but the edge effect is insufficient, so that the existing common scooter for children has poor ground gripping performance, is easy to sideslip and has potential safety hazards; the granular patterns for the light cross-country pump passage have better ground gripping and sideslip preventing performance, but the tires are heavier, the acceleration performance is not good, and the competition result is influenced. In order to ensure that a professional scooter has excellent performance during various road surface competitions and obtain good competition results under the condition of safety, the design of a tire tread pattern with the road condition requirement performance needs to be researched aiming at various indoor places, asphalt ways and light off-road conditions, so that the problems are solved.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 3, the present invention discloses a tread pattern structure of a baby walker. Wherein the vertical direction is set to the tire circumferential direction, the lateral direction is set to the tire axial direction, the single-dot chain line represents the equatorial plane, CL represents the tread center line, and the arrow points represent the running direction of the tire. In fig. 1, the tire tread is formed by arranging a plurality of block units 1 at intervals, and each block unit 1 includes: the central pattern block 10 positioned in the center of the tread and the side pattern groups 20 positioned on two sides of the tread (for the convenience of understanding, the shaded filling part in fig. 1 represents the side pattern group 20), the two side pattern groups 20 are symmetrically configured by taking the tread center line CL as a reference, so that each pattern block unit 1 is integrally in a herringbone shape and points to the running direction of the tire, the rolling resistance of the tire can be reduced, and the competition speed can be improved. Wherein each side pattern group 20 is composed of a plurality of small quadrangular blocks, each quadrangular area being smaller than the area of the central block 10, preferably: each side pattern group 20 is composed of 4-10 quadrangles (in the embodiment, 8 quadrangles are taken as an example), if the number of the quadrangles composing the side pattern group 20 is too small, the edge effect which can be generated is also less, and the ground-grasping performance is not good; if the number of the quadrangles constituting the side pattern group 20 is too large, the area of each quadrangle is small, the rigidity of the two side edges of the tread is greatly weakened, and potential safety hazards are caused.

In addition, dense undulations 30 are provided on the surface of the small blocks of the both-side groups 20 (for the sake of distinction, the solid filled portions in fig. 2 represent the peaks of the undulations 30), preferably, strip-shaped undulations 30b are provided on the two quadrilateral surfaces located at the tread edge, angular undulations 30a are provided on each quadrilateral small block surface between the center block 10 and the two quadrilaterals of the tread edge, and as shown in connection with fig. 3, the depths of the undulations 30 are gradually reduced from the tread center to the tread edge, that is, h1 > h2 > h3 > h 4. The angular raised grains 30a can increase the multi-angle and multi-directional edge effect, improve the ground gripping performance and the sideslip prevention performance during straight-going turning and bending and increase the safety coefficient; the strip-shaped raised grains 30b are arranged on the two quadrilateral surfaces of the edge of the tread and are shallow in depth, so that the grip performance is improved, the rigidity of the edge of the tread is ensured, the problem that the tread cannot be straightened in time due to the over-weakened rigidity after the tread is bent at a large angle is avoided, and the potential safety hazard is reduced.

To sum up, the utility model discloses the tire tread is formed by 1 interval arrangements of a plurality of decorative pattern piece units, and every "people" font decorative pattern piece unit 1 contains: the tread comprises a central pattern block 10 positioned in the center of the tread and side pattern groups 20 positioned on two side edges of the tread, wherein each side pattern group 20 consists of a plurality of small quadrilateral pattern blocks, and the area of each quadrilateral is smaller than that of the central pattern block 10, so that the rolling resistance of the tire can be reduced, and the competitive speed can be increased; the thin grooves 10a are arranged on the surfaces of the two sides of the central pattern block 10, the strip-shaped raised grains 30b are arranged on the quadrilateral surfaces at the edges of the tread, the angular raised grains 30a are arranged on the quadrilateral surfaces between the central pattern block 10 and the edges of the tread, the depth of the raised grains is gradually reduced from the center of the tread to the edges of the tread, the ground gripping and sideslip preventing performance of the patterns can be further improved, the rigidity of the edges of the tread is ensured, the potential safety hazard is reduced, the comprehensive performance is excellent, and the tread is suitable for various indoor field, asphalt road way and light cross-country road condition.
