Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle tires, and in particular relates to a tire with a variable diameter. Background Art
[0002] Traditional automobile tires have limited maneuverability in complex terrain, such as deserts, Gobi deserts, and muddy areas. Variable-diameter tires, on the other hand, can adjust their diameter based on terrain changes, enhancing the vehicle's ability to navigate obstacles and maneuverability. The varying tire diameter helps maintain a stable driving posture, reduces bumps and vibrations, and improves ride comfort under varying road conditions. With the development of the automotive industry, the requirements for tire performance are becoming increasingly diverse. Variable-diameter tires can meet the needs of different vehicles and applications, offering a broad range of applications.
[0003] Existing variable-diameter tires divide the complete tire into multiple arc-shaped tires and change the tire diameter by adjusting the distance between the arc-shaped tires and the rotating axle. However, when the tire diameter becomes larger, a gap will appear between two adjacent arc-shaped tires, causing the vehicle to be bumpy when moving, and the vehicle's ride comfort cannot be guaranteed.

DETAILED DESCRIPTION
[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0028] A typical implementation of the present invention is as follows: Figure 1 and Figure 2 As shown, a variable diameter tire includes a rotating disk 1, a limiting disk 2 and a curved tire 3. The rotating disk 1 is provided with three rotating disks, namely a first rotating disk 11, a second rotating disk 12 and a third rotating disk 13. The axes of the first rotating disk 11, the second rotating disk 12 and the third rotating disk 13 are connected by a rotating shaft 14. The first rotating disk 11, the second rotating disk 12 and the third rotating disk 13 are spaced apart by a set distance. The rotating disk 1 and the rotating shaft 14 are integrally formed.
[0029] like Figure 3As shown, there are three limit plates 2, namely the first limit plate 21, the second limit plate 22 and the third limit plate 23. The axes of the first limit plate 21, the second limit plate 22 and the third limit plate 23 are all provided with axial holes. The first limit plate 21, the second limit plate 22 and the third limit plate 23 are sleeved on the outside of the rotating shaft 14 through the axial holes and are rotatably connected to the rotating shaft 14, wherein the first limit plate 21 is located between the first rotating disk 11 and the second rotating disk 12, and the thickness of the first limit plate 21 is equal to the distance between the first rotating disk 11 and the second rotating disk 12, the second limit plate 22 is located between the second rotating disk 12 and the third rotating disk 13, and the thickness of the second limit plate 22 is equal to the distance between the second rotating disk 12 and the third rotating disk 13, and the third limit plate 23 is located on the side of the third rotating disk 13 away from the second limit plate 22.
[0030] In this embodiment, the arc-shaped tire 3 is a 1 / 6 wheel, that is, six arc-shaped tires 3 can be combined to form a circular wheel, such as Figure 6 As shown, a tread 31 is provided on the outer arc surface of the arc-shaped tire 3, and an anti-skid groove is provided on the tread 31. A limiting rod 32 is provided on the inner arc surface of the arc-shaped tire 3. One end of the limiting rod 32 is connected to the inner arc surface, and the other end is fixedly connected with a guide column 33 and a limiting column 34 on both sides. The guide column 33 and the limiting column 34 are both arranged perpendicular to the limiting rod 32, and the guide column 33 and the limiting column 34 extend toward the side directions of both sides of the arc-shaped tire 3 respectively.
[0031] like Figure 4 and Figure 5 As shown, a plurality of movable cavities 24 are provided inside the limiting disk 2, and the plurality of movable cavities 24 are evenly distributed around the axis of the limiting disk 2. A plurality of through holes 25 are provided on the outer circumferential surface of the limiting disk 2, and the plurality of through holes 25 are provided corresponding to the plurality of movable cavities 24, and the through holes 25 are adapted to the limiting rod 32. A limiting hole 26 is provided on the side wall on one side of the movable cavity 24, and a limiting groove 27 is provided on the side wall on the other side. The length of the limiting hole 26 is the same as the length of the movable cavity 24, and the length of the limiting groove 27 is the same as the length of the limiting hole 26. The limiting hole 26 is adapted to the guide column 33 at the end of the limiting rod 32, and the limiting groove 27 is adapted to the limiting column 34 at the end of the limiting rod 32.
[0032] like Figure 3 As shown, during installation, one end of the limit rod 32 passes through the through hole 25 and enters the movable cavity 24, the guide column 33 at the end of the limit rod 32 is located in the limit hole 26, and the limit column 34 at the end of the limit rod 32 is located in the limit groove 27, so that the arc tire 3 can move up and down along the length direction of the limit rod 32, and the limit column 34 and the guide column 33 are used to limit the movement of the arc tire 3.
[0033] In this embodiment, six movable cavities 24 are provided in the limit plate 2, and each movable cavity 24 is slidably connected to a curved tire 3. When the six curved tires 3 slide to the lowest point, the six curved tires 3 are combined to form a circular wheel. During assembly, the angles between the three limit plates 2 differ by 30°, so that the curved tires 3 on the three limit plates 2 are staggered to ensure that when the curved tire 3 slides to the highest point, that is, after the wheel diameter increases, there is always a curved tire 3 in contact with the ground.
[0034] like Figure 2 and Figure 7 As shown, a plurality of guide holes 15 are provided on the rotating disk 1, and the plurality of guide holes 15 are all arc-shaped. The plurality of guide holes 15 are arranged correspondingly to the plurality of limiting holes 26 on the adjacent limiting disk 2, that is, the plurality of guide holes 15 on the first rotating disk 11 are arranged correspondingly to the plurality of limiting holes 26 on the first limiting disk 21, the plurality of guide holes 15 on the second rotating disk 12 are arranged correspondingly to the plurality of limiting holes 26 on the second limiting disk 22, and the plurality of guide holes 15 on the third rotating disk 13 are arranged correspondingly to the plurality of limiting holes 26 on the third limiting disk 23. One end of the guide hole 15 is arranged close to the axis of the rotating disk 1, and the other end extends toward a side away from the axis of the rotating disk 1, and the plurality of guide holes 15 are all bent to the same side. The guide column 33 passes through the limiting hole 26 and the guide hole 15 in sequence. When the rotating disk 1 rotates, the guide hole 15 drives the guide column 33 to move along the length direction of the limiting hole 26, thereby realizing the up and down movement of the arc tire 3, and then realizing the change of the diameter of the wheel.
