Wheel and mobility including the same
View Patent ↗A wheel includes a deformable part reversibly deformable in shape by an external force, wherein the deformable part includes an inner region having a shape extending in a peripheral direction, an outer region having a shape extending in the peripheral direction and spaced apart outward from the inner region in a radial direction, and a spoke region provided between the inner region and the outer region and having a first side connected to the inner region and a second side connected to the outer region. The spoke region includes a first spoke region having a section protruding in a first of two peripheral directions and a second spoke region disposed at a first side of the first spoke region based on a second of the two peripheral directions opposite the first peripheral direction, wherein the second spoke region has a section protruding in the second peripheral direction.
1. A wheel comprising:
a deformable part that can be reversibly deformed in shape by an external force, wherein the deformable part comprises:
an inner region having a shape extending in a peripheral direction;
an outer region having a shape extending in the peripheral direction and spaced apart outward from the inner region in a radial direction; and
a spoke region provided between the inner region and the outer region and having a first side connected to the inner region and a second side connected to the outer region, wherein the spoke region comprises:
a first spoke region having a section protruding in a first of two peripheral directions; and
a second spoke region disposed at a first side of the first spoke region based on a second of the two peripheral directions, the second peripheral direction opposite to the first peripheral direction, wherein the second spoke region has a section protruding in the second peripheral direction,
wherein a thickness of the first spoke region at a portion where the first spoke region is connected to the inner region is larger than a thickness of the first spoke region at a portion where the first spoke region is connected to the outer region.
2. The wheel of claim 1 , wherein:
the spoke region is one of a plurality of spoke regions, and
each of the plurality of spoke regions is disposed in the peripheral direction.
3. The wheel of claim 2 , wherein a first interval between the outer region and a section of the first spoke region, which protrudes by a largest amount in the first peripheral direction, is larger than a second interval between the outer region and a section of the second spoke region that protrudes by a largest amount in the second peripheral direction.
4. The wheel of claim 2 , wherein a first interval between a region in which the first spoke region and the outer region meet and a region in which the second spoke region and the outer region meet is larger than a second interval between a region in which the first spoke region and the inner region meet and a region in which the second spoke region and the inner region meet.
5. The wheel of claim 2 , wherein the plurality of spoke regions is disposed at intervals that allow the first spoke region, and the second spoke region spaced apart from the first spoke region in the first peripheral direction to come into direct contact with each other when an external force of a predetermined magnitude or higher is applied to the outer region in the radial direction.
6. The wheel of claim 1 , wherein the first spoke region is longer than the second spoke region.
7. The wheel of claim 1 , wherein the first spoke region is thicker than the second spoke region.
8. The wheel of claim 1 , wherein a first interval between the outer region and a section of the first spoke region, which protrudes by a largest amount in the first peripheral direction, is smaller than a second interval between the inner region and a section of the first spoke region that protrudes by a largest amount in the first peripheral direction.
9. The wheel of claim 1 , wherein a third interval between the outer region and a section of the second spoke region, which protrudes by a largest amount in the second peripheral direction, is smaller than a fourth interval between the inner region and a section of the second spoke region that protrudes by a largest amount in the second peripheral direction.
10. The wheel of claim 1 , wherein a thickness of the second spoke region at a portion where the second spoke region is connected to the inner region is larger than a thickness of the second spoke region at a portion where the second spoke region is connected to the outer region.
11. The wheel of claim 1 , wherein a portion where the first spoke region is connected to the outer region is directed away in the peripheral direction from a portion where the first spoke region is connected to the inner region.
12. The wheel of claim 1 , wherein a portion where the second spoke region is connected to the outer region is directed away in the peripheral direction from a portion where the second spoke region is connected to the inner region.
13. The wheel of claim 1 , wherein a portion where the first spoke region is connected to the outer region is directed away in the second peripheral direction from a portion where the first spoke region is connected to the inner region.
14. The wheel of claim 1 , wherein a portion where the second spoke region is connected to the outer region is directed away in the second peripheral direction from a portion where the second spoke region is connected to the inner region.
15. The wheel of claim 1 , further comprising:
a core part provided inside the inner region in the radial direction and having a first side fixedly coupled to the inner region; and
a connection part having a first side connected to the core part and a second side connected to the outer region.
16. A wheel comprising:
a deformable part that can be reversibly deformed in shape by an external force, wherein the deformable part comprises:
an inner region having a shape extending in a peripheral direction;
an outer region having a shape extending in the peripheral direction and spaced apart outward from the inner region in a radial direction; and
spoke regions provided between the inner region and the outer region, each of the spoke regions having a first side connected to the inner region and a second side connected to the outer region, wherein the spoke regions are spaced apart from one another in the peripheral direction, and wherein each of the spoke regions comprises:
a first spoke portion extending outward from the inner region in the radial direction;
a second spoke portion extending from the first spoke portion in a first peripheral direction of two directions of the peripheral direction; and
a third spoke portion extending outward from the second spoke portion in the radial direction and connected to the outer region.
17. The wheel of claim 16 , wherein:
the first spoke portion extends outward from the inner region in the radial direction and extends to be directed in a second peripheral direction opposite to the first peripheral direction of the peripheral direction; and
the third spoke portion extends outward from the second spoke portion in the radial direction and extends to be directed in the second peripheral direction.
18. The wheel of claim 16 , wherein a first region in which the second spoke portion and the third spoke portion of a first spoke region of the spoke regions meet is spaced apart outward, in the radial direction, from a second region in which the first spoke portion and the second spoke portion meet in a second spoke region of the spoke regions that is spaced apart from the first spoke region in the first peripheral direction of the peripheral direction.
