Specifically, a plurality of cavities 11 are arranged on the tire body 10 at intervals along the circumferential direction, and in the preferred embodiment, the cavities 11 are arranged at equal intervals; the opening 111 of the cavity 11 is located on the inner circumferential surface of the tire body 10, the bottom of the cavity 11 is opposite to the opening 111, and the thickness between the bottom of the cavity 11 and the tire of the tire body 10 is not less than a threshold thickness, wherein the thickness can be set according to the specific specification of the tire and the use environment of the tire; between adjacent openings 111, that is to say, between two adjacent cavities 11, there are connecting portions 12, where the connecting portions 12 are used to connect two sidewalls of the tire 10 in the thickness direction, the end connecting portions 122 are located at two ends of the middle connecting portion 121 and are respectively used to connect two sidewalls, where the middle connecting portion 121 is located at the middle position of the tire 10 and is a concentrated and main pressure-bearing position, and the two end connecting portions 122 are located at two sidewalls of the tire 10 and play roles of assisting pressure-bearing and balancing the tire.
In this embodiment, the width of the middle position of the middle connecting portion 121 is greater than the widths of the two end positions, that is, the middle connecting portion 121 is thick at the middle and thin at the two sides, so that the opening 11 between two adjacent connecting portions 12 is in a soap shape, that is, the middle is small and the two ends are large; therefore, because the middle position of the tire body 10 bears larger pressure, the thickness of the middle position of the tire body is matched with that of the middle connecting part 121, the pressure born by the positions at the two sides of the tire body 10 is relatively smaller, and the thickness of the middle position of the tire body is matched with that of the positions at the two ends of the tire body 10, namely, the shape of the tire body 10 is matched with the pressure distribution of the tire, the whole vibration damping effect of the tire can be effectively improved, the riding comfort is improved, the abrasion of the tire is small, and the cruising ability is better.
In one preferred embodiment of the present invention, each opening 111 in the tire body 10 is identical in shape.
Specifically, the tire body 10 is provided with a plurality of cavities 11 with the same shape and size, that is, the openings 111 on the inner circumferential surface of the tire body 10 have the same shape, so that when the tire body 10 bears pressure, the tire body has the same bearing capacity no matter where the tire body rotates, and the bumpy feeling caused by the inconsistent bearing capacity can be effectively avoided.
Further, in this embodiment, the cavity 11 and the opening 111 of the tire body 10 may be uniformly distributed along the circumferential direction of the tire body 10, so that the tire body 10 may ensure balanced stress at each position during rolling, and during vehicle driving, the vibration damping effect at each position of the tire is the same, thereby effectively improving comfort, reducing the risk of local loss of the tire, and further prolonging the service life of the tire.
Further, since the end connecting portion 122 is to connect the sidewalls of the tire body 10, in order to enhance the connection strength of the end connecting portion 122 with the sidewalls of the tire body 10 and thus enhance the rigidity and integrity between the connecting portion 12 and the tire body 10, the width of the end connecting portion 122 in the circumferential direction of the tire body 10 is greater than the width of the middle connecting portion 121 in the circumferential direction of the tire body 10, that is, the width of the connecting portion between both ends of the middle connecting portion 121 and two sidewalls of the tire body 10 in the circumferential direction of the tire body 10, as shown by width D in fig. 2, is greater than the maximum width of the middle connecting portion 121 in the circumferential direction of the tire body 10, that is, the maximum thickness of the middle connecting portion 121.
In addition, the distance from both ends of the opening 111 to the edge of the tire body 10 is equal in the width direction of the tire body 10.
Specifically, the cavity 11 is disposed in the middle of the tire body 10, so that the thicknesses of the sidewalls at two sides of the cavity 11 are equal, and the distances from two ends of the opening 111 to the edges of the tire body 10, that is, two sidewalls, are equal, so that the thicknesses of the sidewalls at two sides of the cavity 11 in the width direction of the tire body 10 are equal, and the thicknesses of the portions where two ends of the opening 111 are connected to the sidewalls are equal, so that the inner side and the outer side of the tire body 10 have the same pressure-bearing capacity, which is beneficial to improving the balance of the tire body 10 during rolling.
Further, the openings 111 are axisymmetric structures symmetrically distributed in the width direction or the circumferential direction of the tire body 10.
Specifically, the opening 111 may be an axisymmetric structure symmetrically distributed in the width direction of the tire body 111, the vertical dotted line as shown in fig. 2 being the axis of symmetry; the openings 111 may also be axisymmetric structures symmetrically distributed in the circumferential direction of the tire body 10, the axis of symmetry being the lateral dotted line as shown in fig. 2; due to the design of the shape, the tire body 10 has the same pressure bearing capacity in the two tire side directions, uniform stress is achieved, the tire does not swing left and right in the vehicle running process, and the running stability of the vehicle is guaranteed.
In another preferred embodiment of the present invention, the width of the middle portion of the middle connecting portion 121 decreases gradually from the middle position to the two end positions of the middle connecting portion 121.
Specifically, the width of the middle connection portion 121 gradually decreases from the middle position to the two end positions, that is, the width gradually increases from the end of the middle connection portion 121 to the middle position of the middle connection portion 121, so that the design is more suitable for the pressure-bearing distribution of the tire body 10, and is more beneficial to improving the rolling stability of the tire body 10.
Furthermore, the width of the middle connection part 121 gradually decreases from the middle position of the middle connection part 121 to the two end positions of the middle connection part 121, so that the design can be further matched with the pressure-bearing distribution of the tire body 10, and the rolling stability of the tire body 10 can be improved.
Further, in one possible embodiment of the present invention, the widths of the two end positions of the middle connection portion 121 are equal. Here, since the two end positions of the middle connection portion 121 have the same width, and accordingly have the same pressure-bearing capacity, the symmetrical balance of the pressure-bearing of the middle connection portion 121 in the width direction of the tire body 10 can be further improved, so as to effectively improve the rolling stability of the tire body 10.
In addition, referring to fig. 3, in another possible embodiment of the present invention, the widths of the two ends of the middle connection portion 121 are not equal. Here, the width of the middle connection portion 121 at two ends can be differentiated according to the pressure of the middle connection portion 121 in the width direction of the tire body 10, such as one side is larger and the other side is smaller, and one end is wider and the other end is narrower.
Further, in the case where the widths of the both end positions of the middle connection portion 121 are not equal, in order to balance the pressure-bearing capacities of the both ends of the middle connection portion 121 in the width direction of the tire body 10, the directions from the end portion of larger width to the end portion of smaller width are opposite in the adjacent two middle connection portions 121, as shown by the arrow direction in fig. 3. Because the widths of the two ends of the middle connecting part 121 are not equal, the two ends of the tire body 10 in the width direction have different pressure-bearing capacities, if the connecting parts 12 are arranged in the same direction, the pressure-bearing capacity of one side of the tire body 10 is greatly different from the pressure-bearing capacity of the other side of the tire body, and the tire body 10 is easy to deviate to one side when rolling, so that the driving safety of a vehicle is affected; in this embodiment, two large and small end portions of two adjacent middle connection portions 121 are alternately arranged, that is, the directions from the end portion with the larger width to the end portion with the smaller width are opposite, so that the connection portions 12 can be effectively prevented from being arranged in the same direction, the pressure bearing capacity of the tire body 10 at two ends in the width direction is equal, and the rolling stability of the tire body 10 is effectively improved.
In addition, in other preferred embodiments of the present invention, ribs 112 are provided at the bottom of the plurality of cavities 11 along the circumferential direction of the tire body 10.
Specifically, a rib 112 is provided at the cavity bottom of the cavity 11, and a plurality of ribs 112 are connected together in the circumferential direction of the tire body 10. In a preferred embodiment, the rib 112 is disposed at the middle position of the tire 10 along the width direction of the tire 10, and the arrangement of the rib 112 can improve the pressure resistance of the tire 10 and match the pressure distribution characteristics of the tire 10 with large pressure bearing in the middle and small pressure bearing in both sides.
Further, the inner corners of the opening 111 are in arc transition.
Specifically, the included angles of the openings 111 in the width direction of the tire body 10 and in the circumferential direction of the tire body 10, that is, the inner corners of the openings 111 are in the arc transition structure, so that the reduction of the tensile strength due to too sharp angles can be effectively avoided, thereby preventing the cracks or tearing phenomena occurring at the corners of the inner corners, and effectively improving the use quality of the tire body 10.
