[0038] Example 1

[0039] Example 1 provides an inner support body, as shown in Figures 1 and 2. The inner support body 1 has a ring structure and its outer side is connected to the inner side of the tread 2 through a connector. The outer side of the inner support body 1 is provided with an outwardly protruding outer support part 111. The outer support part 111 slightly presses the inner side of the tread 2 to make the tread 2 partially bulge.

[0040] In this embodiment, the annular inner support 1 is connected to the inner side of the tread 2 via a connector, and the outer side of the inner support 1 is provided with an outer support portion 111 protruding towards the tread 2. The outer support portion 111 slightly presses the inner side of the tread 2 to make the tread 2 partially bulge. Through the improvement of the structure of the inner support 1 itself, the inner support 1 and the tread 2 can be well matched, so that the tread 2 can cope with various complex or uneven ground environments and prevent the tire from getting stuck in obstacles.

[0041] In this embodiment, the outer side of the inner support body 1 is provided with an inwardly recessed inner support portion 112.

[0042] In this embodiment, the tread 2 is also an annular structure, as shown in Figure 3. The inner support 1 includes one or more inner bearing rings 11. The inner bearing rings 11 are annular structures, and adjacent inner bearing rings 11 are connected by a connector. One or more inner bearing rings 11 are coaxially arranged with the tread 2. The inner side of the inner bearing ring 11 is provided with an inwardly recessed inner support portion 112 and the outer side is provided with an outwardly protruding outer support portion 111.

[0043] In this embodiment, as shown in FIG1, when the inner support body 1 includes an inner bearing ring 11, the outer support part 111 presses against the inner side of the tire tread 2.

[0044] In this embodiment, as shown in FIG3, when the inner support body 1 includes multiple inner bearing rings 11, the multiple inner bearing rings 11 are stacked in sequence. The outer support portion 111 of the inner bearing ring 11 closest to the tread 2 presses against the inner side surface of the tread 2. In two adjacent inner bearing rings 11, the inner support portion 112 of one inner bearing ring 11 and the outer support portion 111 of the other inner bearing ring 11 are positioned correspondingly to prevent the inner bearing rings 11 from shifting when multiple inner bearing rings 11 are combined.

[0045] By configuring the inner support 1 as a structure comprising multiple inner bearing rings 11, with adjacent inner bearing rings 11 and connecting bodies forming a sandwich shell structure, this structure is characterized by its light weight, high strength, and high rigidity, and achieves good vibration resistance, heat insulation, sound insulation, and other necessary properties. Furthermore, by avoiding large-area riveting, stress concentration is reduced, resulting in a significant improvement in fatigue strength. Due to these advantages, sandwich shell structures are increasingly widely used in various military and civilian sectors. Mechanically, the two inner bearing rings 11 serve as the main load-bearing layers, while the connecting bodies form a sandwich structure that expands and firmly bonds the two inner bearing rings 11 together, bearing shear stress. This is similar to the concept of an I-beam, where the two inner bearing rings 11 act as flanges, and the connecting bodies form a sandwich structure that acts as a web.

[0046] In this embodiment, the connector is made of a flexible and elastic material to give it high strength and high toughness. The connector is evenly laid between the tread 2 and the inner bearing ring 11, or between two adjacent inner bearing rings 11, to maximize the contact area between the outer tread 2 and the inner bearing ring 11, thereby increasing the bonding strength. Furthermore, the even laying of the connector ensures a stable connection between the outer tread 2 and the inner bearing ring 11, or between two adjacent inner bearing rings 11, improving the stability and safety of the overall structure.

[0047] In this embodiment, as shown in Figures 1-5, the cross-sections of the outer support 111 and the inner support 112 are umbrella-shaped, so as to further apply gradually increasing and smooth pressure to the tread 2 from both sides of the inner bearing ring 11 to the middle of the inner bearing ring 11, so that the tread 2 can safely pass through various complex or uneven ground environments without reducing the bearing capacity of the tread 2, but rather increasing the bearing capacity of the tread 2 to a certain extent.

[0048] In this embodiment, the radii of the outer support portion 111 and the inner support portion 112 are much smaller than the radius of the inner bearing ring 11, ensuring that the pressure of the outer support portion 111 on the tread 2 is a small pressure, preventing excessive pressure from affecting the normal driving of the tread 2.

[0049] In this embodiment, there is one or more outer support parts 111 and / or inner support parts 112, and the outer support parts 111 and / or inner support parts 112 are integrally formed with the inner support body 1 or fixedly connected by welding.

[0050] In this embodiment, as shown in Figures 1 and 3, when there is one outer support 111 and / or one inner support 112, the outer support 111 and / or the inner support 112 are annular, and the outer support 111 is located in the middle of the outer side surface of the inner support body 1, so as to support the middle of the tread 2 through one outer support 111 and prevent the tread 2 from shifting. The inner support 112 is located in the middle of the inner side surface of the inner support body 1.

[0051] In this embodiment, as shown in Figures 4 and 5, when there are multiple outer support parts 111, the outer support parts 111 are ring-shaped or hill-shaped, and multiple outer support parts 111 are symmetrically arranged on the outer side of the inner support body 1, so as to support the middle part of the tread 2 through multiple outer support parts 111 and prevent the tread 2 from shifting.

[0056] Example 3

[0057] Example 3 provides a tire, as shown in Figures 6 and 7, comprising:

[0058] Tread 2;

[0059] The aforementioned inner support 1 is located inside the tread 2.

[0061] The outer support member 4 is located inside the middle support member 3;

[0062] The elastic support 5 is disposed inside the outer support 4;

[0063] The tread 2, inner support 1, middle support 3, outer support 4, and elastic support 5 are all coaxially arranged.
