Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

A high-elasticity bicycle tire comprises a tire tread 1 and an ellipsoid layer 2, wherein the ellipsoid layer 2 is formed by connecting hollow ellipsoids 22 sequentially around the axle center of the tire tread 1, the adjacent ellipsoids 22 are intersected on the surface corresponding to the short axis of the ellipsoid 22, namely the short axis is parallel to the axial line in the ellipsoid 22, the intersection position of the ellipsoid 22 is completely penetrated, namely the edge line of the intersection position of the ellipsoid 22 and the intersection position is in a completely penetrated state, other parts of the intersection position disappear, the ellipsoid 22 is not a complete ellipsoid at the moment but the ellipsoid 22 intercepted on the intersected plane, the side surface of the bicycle tire is an arc surface with alternating concave positions and convex positions formed by the intersection of the ellipsoid 22, an envelope layer 3 is arranged on the arc surface, the envelope layer 3 is completely connected with the concave positions and the convex surfaces of the arc surface, which is equivalent to the effect of reinforcing the ellipsoid 22, the supporting strength of the tire is enhanced when the tire is stressed, and the ellipsoid 22 is of a hollow structure and has enough elasticity, so that the elastic deformation is easy to occur.

In a further improvement, a through hole 31 is formed in the end position of the short axis of the ellipsoid 22 on the surface where the ellipsoid 22 is connected with the encapsulating layer 3, and the through hole 31 is communicated with the ellipsoid 22, so that on one hand, a heat dissipation effect can be achieved, and on the other hand, the problems of increased support strength and weakened elastic yield caused by the arrangement of the encapsulating layer 3 can be solved.

Further improving the comfort of the tire under stress, grooves may be provided in the tread 1. The symmetrical transverse grooves 11 are arranged on the tire tread 1 corresponding to the same ellipsoid connecting positions, the transverse grooves 11 take the edge of the tire tread 1 as a starting point, namely, the grooves are equivalent to openings at the edge of the tire tread 1, the two symmetrically arranged transverse grooves 11 are not intersected and have a certain interval, the two symmetrically arranged transverse grooves 11 are arranged along a tire tread arc line, and the tire tread arc line is an arc line of a section passing through the tire tread 1 by a plane where an axial line passing through an axle center is located. The symmetrically arranged transverse grooves 11 are used as a row, two pairs of oblique grooves 12 are arranged between two adjacent rows of transverse grooves 11, and the two pairs of oblique grooves 12 are also symmetrically arranged, namely, each pair of oblique grooves 12 is positioned between two adjacent transverse grooves 11 on the same side of the edge of the tread 1. Each pair of the diagonal grooves 12 includes one short groove 121 and one long groove 122, and since the diagonal groove 12 is located between the two lateral grooves 11, the long groove 122 starts from a position close to one of the lateral grooves 11 and the edge of the tread 1, extends toward an end point of the other lateral groove 11 distant from the edge position, and the starting position is communicated with the lateral grooves 11. The short groove 121 is located inside the long groove 122, and the inclined direction of the short groove 121 is consistent or relatively consistent with the long groove 122, i.e. parallel or not parallel, but the inclined direction is consistent. Through setting up the recess, can avoid tread 1 solid, the too big problem of hardness, tread 1 when contact ground atress, the power can be earlier through the tread 1 production elasticity yield by the recess is cut apart to conduct power to on the ellipsoid 22, thereby strengthened the comfort level that tread 1 contacted ground. When the tread 1 is connected with the ellipsoids 22, the transverse groove 11 is located on the tread 1 corresponding to the intersection position of the two ellipsoids 22, the surface of the ellipsoid layer 2 is just a concave position, and the thickness of the tread 1 connected with the ellipsoid layer 2 is inevitably increased at the position, so the strength at the position is also higher, and the groove depth of the transverse groove 11 at the position can be improved, that is, the groove depth of the transverse groove 11 at the position is gradually decreased from the end part close to the edge to the other end, so the tread 1 close to the edge is naturally thinned, and elastic deformation is easier to occur.

Two annular grooves 21 are arranged on the surface of the ellipsoidal layer 2 close to the axle center of the tread 1, and the annular grooves 21 are arranged in parallel relatively, so that the ellipsoidal body 22 can be used as a hub connecting part from the annular grooves 21 to the end point close to the ellipsoidal body 22, and the hub connecting part is convenient to connect with a hub.

Further improve the travelling comfort that tread 1 contacted the ground, can be provided with lug 13 between long recess 122 and tread 1 edge, lug 13 is according to arranging with tread 1 edge line parallel array and distributes, begins by tread 1 edge, and lug 13 divide into three parallel array, and there are 4 lugs 13 in the edge closest to tread 1, and the back reduces in proper order, has two lugs 13 in the place farthest from tread 1 edge. Because the tread 1 is the arcwall face, the centre is high, the shape that both sides edge is low, so when tread 1 atress, take place elastic yield, only then spread gradually to tread 1 edge position, so the existence of lug 13 can play the effect of transition. Of course, the arrangement or number of lugs 13 is not strictly limited as long as it provides an effective transition when the tread 1 is subjected to a force.

In order to further enhance the strength of the connection of the ellipsoids 22, a smooth transition process may be performed at the position where the ellipsoids 22 intersect, where the smooth transition process means that the sharp corner originally formed when the two ellipsoids 22 intersect is passivated, so that the two ellipsoids form an arc-shaped surface, and since the outer surface of the ellipsoid 22 of the present invention is covered with the envelope layer 3, the smooth transition process is substantially implemented in the hollow inner structure of the ellipsoid layer 2. The intersecting position is in smooth transition, so that the fracture of the intersecting position caused by overlarge stress and overlarge elastic deformation can be further prevented, which also means that the tire can be stressed more greatly.

The material of the tread 1 and the ellipsoidal layer 2 in the present invention is a high molecular polymer having a shore hardness of 55A to 60D, and any high molecular polymer satisfying the hardness requirement can be used as the material of the present invention, and polyurethane is selected as the high molecular polymer in the present embodiment in order to further consider the heat resistance and wear resistance of the tire.

In addition, the invention can be formed by connecting the tread and the ellipsoidal layer, and can also be formed into an integrated structure by injection molding, which can be determined according to the use condition and the use environment of the bicycle.

The present invention is not limited to the one shown in the drawings as to the number of ellipsoids in the ellipsoidal layer, and the number of ellipsoids in the ellipsoidal layer may be 7 to 120, that is, 7, 20, 50, 80, 100, 120, etc., which are not listed herein, and even a tire composed of a different number of ellipsoids satisfies the index requirements as a bicycle tire as long as the number of ellipsoids therein is within a limited range.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
