Description

Technical Field

[0001] The invention relates to the technical field of wheel structures, and in particular to a tire structure. Background Art

[0002] Tires are divided into pneumatic tires and airless tires. Traditional pneumatic tires are widely used because of their mature production technology, shock absorption, good riding comfort and good load-bearing capacity. However, with the increasing number of vehicle driving safety accidents caused by tire blowouts, wear and unstable operation, airless tires have no inner tubes and have the advantages of high safety, energy saving and environmental protection, which have attracted more and more attention. Airless tires are generally solid tires, but it has been observed that solid tires have poor shock absorption effect.

[0003] In view of this, the designer has conducted in-depth research on the above-mentioned deficiencies and inconveniences and thus came up with this project. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a tire structure with good shock absorption effect.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A tire structure includes a tire body, wherein the tire body is provided with a tread, a sidewall connecting the two ends of the tread, and a tire lip connecting the sidewall; a plurality of cavities with openings facing inward are provided in the tire body, and the plurality of cavities are evenly arranged along the circumference of the tire body; a dividing piece is provided between two adjacent cavities, and at least one of the dividing pieces is formed with a through hole connecting the two adjacent cavities at one end close to the tread.

[0007] At least one of the split pieces includes a first split piece and a second split piece, the two sidewalls are the first sidewall and the second sidewall, the first split piece is connected to the first sidewall, and the second split piece is connected to the second sidewall; one end of the first split piece close to the tread is recessed toward the first sidewall to form a first arc-shaped portion; one end of the second split piece close to the tread is recessed toward the second sidewall to form a second arc-shaped portion; the first arc-shaped portion, the second arc-shaped portion and the inner side surface of the tread cooperate to form the through hole.

[0008] The tire structure further includes an insert that fits at the opening of the cavity.

[0009] The size of the insert is greater than or equal to the opening size of the cavity.

[0010] When the first dividing piece and the second dividing piece are in contact with each other, the opening width of the chamber is k1, and the width k2 of the insert is greater than or equal to the opening width k1 of the chamber.

[0011] The insert is connected with a back plate, and the back plate is pressed against the tire lip.

[0012] The width of the back plate is equal to the bead width when the insert is assembled in the cavity opening.

[0013] The back plate is made of soft material.

[0014] After adopting the above scheme, the present invention increases the deformation space of the tire by setting a plurality of chambers in the tire body, thereby improving the shock absorption effect of the outer tire. At the same time, by setting a through hole at one end of the split piece close to the tread, the problem of the tire jumping during use is effectively avoided. In addition, the present invention divides the split piece into a first split piece and a second split piece, so that the cavity opening of the tire body has a larger deformation space, thereby facilitating the demoulding operation during the tire preparation process, improving production efficiency and reducing production costs. The present invention also adds an inlay and a back plate to avoid the misalignment problem when assembling the tire and the wheel rim, and improves the flexibility of tire assembly so that the tire can adapt to wheel rims of different sizes.

DETAILED DESCRIPTION

[0024] like Figures 1 to 7As shown, the present invention discloses a tire structure, which includes a tire body 10, wherein the tire body 10 is provided with a tread 11, a sidewall 12 connecting two ends of the tread 11, and a tire lip 13 connecting the sidewall 12; a plurality of chambers 14 with openings facing inward are provided in the tire body 10, and the plurality of chambers 14 are evenly arranged along the circumference of the tire body 10; a dividing piece 15 is provided between two adjacent chambers 14, and at least one of the dividing pieces 15 is formed with a through hole 153 connecting the two adjacent chambers 14 at one end close to the tread 11.

[0025] The present invention increases the deformation space of the tire by arranging multiple chambers 14 in the tire body 10, thereby improving the shock absorption effect of the tire. At the same time, by arranging a through hole 153 at one end of the splitter 15 close to the tread 11, the problem of the tire jumping during use is effectively avoided.

[0026] Embodiment 1

[0027] like Figures 1 to 3 As shown, in this embodiment, the splitter 15 includes a first splitter 151 and a second splitter 152, and the two sidewalls 12 of the tire body 10 are the first sidewall 121 and the second sidewall 122. The first splitter 151 is connected to the first sidewall 121, and the second splitter 152 is connected to the second sidewall 122; one end of the first splitter 151 close to the tread 11 is recessed toward the first sidewall 121 to form a first arc-shaped portion 1511; one end of the second splitter 152 close to the tread 11 is recessed toward the second sidewall 122 to form a second arc-shaped portion 1521; the first arc-shaped portion 1511, the second arc-shaped portion 1521 and the inner side surface of the tread cooperate to form a through hole 153.

[0028] When the tire is mounted on the wheel rim, the bead 13 of the tire body 10 is close to the wheel rim, and the first segment 151 and the second segment 152 are pressed against each other, thereby separating two adjacent chambers 14. However, due to the arrangement of the first arc-shaped portion 1511 and the second arc-shaped portion 1521, the first segment 151 and the second segment 152 cooperate to form the through hole 153, which connects the two adjacent chambers 14. Moreover, since the through hole 153 is located at one end of the segment close to the tread 11, the problem of the tire jumping during use is effectively avoided.

[0029] In addition, the present invention divides the partition between the chambers 14 into a first partition 151 and a second partition 152. During the preparation of the tire, the opening of the chamber 14 has a larger deformation space, so that the mold can be more easily separated from the chamber 14, thereby making the preparation of the tire more convenient and less costly.

[0030] 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 actual applications, some of the partitions 15 may not be provided with through holes 153, and these partitions 15 without through holes 153 are an integrated structure, so that a plurality of independent and non-communicating chambers are formed in the tire body 10.

[0031] Embodiment 2

[0032] like Figure 4 and Figure 5 As shown, based on the first embodiment, this embodiment further includes an insert 20, which is matched at the opening of the chamber 14. When the material used by the tire body 10 is relatively soft, the first segment 151 and the second segment 152 may be misaligned during the assembly of the tire body 10 and the wheel rim, thereby affecting the assembly downhill rate or use of the tire. The insert 20 can well prevent the misalignment of the first segment 151 and the second segment 152.

[0033] The size of the insert 20 is greater than or equal to the opening size of the chamber 14. Specifically, when the first segment 151 and the second segment 152 are in contact, if the opening width of the chamber 14 is k1, then the width k2 of the insert 20 is greater than or equal to the opening width k1 of the chamber 14. When the width k1 of the insert 20 is greater than the opening width k1 of the chamber 14, the width of the tire lip 13 of the tire body 10 increases, and the tire body 10 can be adapted to a rim with a larger width. In other words, by adjusting the size of the insert 20, the tire body 10 can be adapted to rims of different widths.

[0034] Embodiment 3

[0035] like Figure 6 and Figure 7 As shown, based on the second embodiment, this embodiment further includes a back plate 30 connected to the insert 20, and when in use, the back plate 30 is pressed against the tire lip 13. The width of the back plate 30 is equal to the width of the tire lip 13 when the insert 20 is assembled at the opening of the cavity 14.

[0036] By providing the back plate 30, the assembly work of the insert 20 on the chamber 14 can be made simpler and more accurate. In addition, by adjusting the thickness of the back plate 30, the tire can be adapted to rims of different diameters, making the assembly of the tire more flexible.

[0037] In addition, the back plate 30 may be made of a soft rubber material, thereby improving the shock absorption effect of the tire.

[0038] In summary, the key to the present invention is that the present invention increases the deformation space of the tire by setting a plurality of chambers 14 in the tire body 10, thereby improving the shock absorption effect of the outer tire. At the same time, by setting a through hole 153 at one end of the split piece close to the tread 11, the problem of the tire jumping during use is effectively avoided. In addition, the present invention divides the split piece into a first split piece 151 and a second split piece 152, so that the opening of the chamber 14 of the tire body 10 has a larger deformation space, thereby facilitating the demoulding operation during the tire preparation process, improving production efficiency and reducing production costs. The present invention also adds an inlay 20 and a back plate 30 to avoid the misalignment problem when the tire is assembled with the wheel rim, and improves the flexibility of tire assembly so that the tire can adapt to wheel rims of different sizes.

[0039] The above description is merely an embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
