Detailed Description

As shown in fig. 1 to 7, the present invention discloses a novel tire structure, which includes a tire body 10, wherein the tire body 10 is provided with a tread 11, sidewalls 12 connecting two ends of the tread 11, and a bead 13 connecting the sidewalls 12; a plurality of cavities 14 with openings facing the inner side are arranged in the tire body 10, and the cavities 14 are uniformly arranged along the circumferential direction of the tire body 10; a partition 15 is arranged between two adjacent chambers 14, and a through hole 153 communicating the two adjacent chambers 14 is formed at one end of at least one partition 15 close to the tread 11.

The utility model discloses a set up a plurality of cavities 14 in tire body 10 to increase the deformation space of tire, and then improve the shock attenuation effect of cover tire. Meanwhile, through the through hole 153 arranged at one end of the partition 15 close to the tread 11, the problem that the tire jumps in the use process is effectively avoided.

Example one

As shown in fig. 1 to 3, in the present embodiment, the dividing member 15 includes a first dividing member 151 and a second dividing member 152, and the two sidewalls 12 of the tire body 10 are a first sidewall 121 and a second sidewall 122. Wherein the first split 151 is connected to the first sidewall 121, and the second split 152 is connected to the second sidewall 122; one end of the first dividing piece 151 close to the tread 11 is recessed toward the first tread 121 to form a first arc 1511; one end of the second dividing member 152 close to the tread 11 is recessed toward the second sidewall 122 to form a second arc portion 1521; the first arc part 1511, the second arc part 1521 and the inner side surface of the sidewall are matched to form a through hole 153.

When the tire is assembled on the rim, the bead 13 of the tire body 10 abuts against the rim, and the first and second dividing

members

151 and 152 abut against each other, thereby dividing the adjacent two chambers 14. However, due to the arrangement of the first arc-shaped portion 1511 and the second arc-shaped portion 1521, the first dividing member 151 and the second dividing member 152 cooperate to form the above-mentioned through hole 153, and the through hole 153 communicates two adjacent chambers 14. And because the through hole 153 is positioned at one end of the dividing piece close to the tread 11, the problem that the tire jumps during use is effectively avoided.

Furthermore, the utility model discloses a divide into first segmentation 151 and second segmentation 152 with the segmentation between the cavity 14, in the preparation process of tire, cavity 14 opening has bigger deformation space for the mould can break away from out from cavity 14 more conveniently, thereby makes the preparation of tire more convenient, and the cost is lower.

In this embodiment, all the partitions 15 are provided with through holes 153, and all the partitions 15 include a first partition 151 and a second partition 152. In practical applications, the through holes 153 may not be formed in some of the partitions 15, and the partitions 15 without the through holes 153 are of an integral structure, so that a plurality of independent and non-communicating chambers are formed in the tire body 10.

Example two

As shown in fig. 4 and 5, in addition to the first embodiment, the present embodiment further includes an insert 20, and the insert 20 is fitted in the opening of the cavity 14. When the material used for the tire body 10 is soft, the first and second dividing

members

151 and 152 may be misaligned during the process of assembling the tire body 10 to the rim, thereby affecting the downhill assembly rate or use of the tire. The insert 20 can prevent the first and second divided

members

151 and 152 from being misaligned.

The insert 20 has a size equal to or greater than the opening size of the cavity 14. Specifically, when the first dividing member 151 and the second dividing member 152 abut against each other, if the opening width of the cavity 14 is k1, the width k2 of the insert 20 is equal to or greater than the opening width k1 of the cavity 14. When the width k1 of the insert 20 is greater than the opening width k1 of the cavity 14, the width of the bead 13 of the tire body 10 is increased, and the rim with larger width can be adapted. That is, by adjusting the size of the insert 20, the tire body 10 can be adapted to rims of different widths.

EXAMPLE III

As shown in fig. 6 and 7, in addition to the second embodiment, the present embodiment further comprises a back plate 30 connected to the insert 20, wherein the back plate 30 is pressed against the bead 13 in use. The width of the back plate 30 is equal to the width of the bead 13 when the insert 20 is fitted in the opening of the cavity 14.

The assembly of the insert 20 in the cavity 14 is made easier and more accurate by the provision of the back plate 30. Moreover, the thickness of the back plate 30 is adjusted, so that the tire can be adapted to rims with different diameters, and the assembly of the tire is more flexible.

In addition, the back plate 30 may be provided as a soft rubber material, thereby improving the shock-absorbing effect of the tire.

To sum up, the utility model discloses a key lies in, the utility model discloses a set up a plurality of cavities 14 in tire body 10 to increase the deformation space of tire, and then improve the shock attenuation effect of cover tire. Meanwhile, through arranging the through hole 153 at one end of the partition close to the tread 11, the problem that the tire jumps in the use process is effectively avoided. Furthermore, the utility model discloses a to cut apart the piece and divide into first segmentation 151 and second segmentation 152, make the cavity 14 opening of tire body 10 have bigger deformation space to make things convenient for the drawing of patterns operation in the tire preparation process, improve production efficiency, reduction in production cost. The utility model discloses still add insert 20 and backplate 30 to dislocation problem when avoiding tire and wheel rim assembly, and the flexibility that improves tire assembly makes the not unidimensional wheel rim of tire adaptation.

The above description is only an embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
