Description

TECHNICAL FIELD

[0001] The present invention relates to a safety device for a tire; in particular, it relates to a run-flat device installed in a tire to support a tire tread. BACKGROUND

[0002] When a vehicle is running on a road, if a tire is punctured by a sharp object, is defective in itself, or is damaged by external force in the environment, thus causing a tire to have a gap and leak air, the tire cannot maintain an inflated state. The tire tread collapses due to the sudden reduction in the diameter of the tire, making it impossible for the tire to roll normally, which can easily cause the vehicle to lose control or even damage the wheel.

[0003] To solve the problem of vehicle loss of control caused by tire air leakage, tire manufacturers have invented a tire with enhanced tire wall strength, which can still provide some support after the tire leaks, allowing the tire to continue rolling and allowing the vehicle to continue driving. Although this tire with increased tire wall strength has the advantage of allowing the tire to continue rolling after it leaks, it is more expensive than a general tire, and the tire body is harder, thus providing less comfort, so there is still a demand in the market to replace this type of tire. SUMMARY

[0004] In view of the above, the purpose of the present invention is to design a device that can be installed in a tire and can support the tire tread when the tire is damaged and loses pressure, allowing the tire to continue rolling and thus avoiding vehicle loss of control for users to use.

[0005] To achieve the above purpose, the present invention provides a run-flat device, which includes a plurality of support elements, a cable ring, and an elastic ring, and the plurality of support elements are fixed to form a bundle ring arranged in a circle around a rotation axis. Two opposite directions along the rotation axis are defined as a first direction and a second direction. Each support element has a main wall, the side of the main wall away from the rotation axis is connected to a hook portion, the hook portion protrudes in the first direction and has a free end, the part of the hook portion adjacent to the free end has a bundle ring groove; the two sides of the main wall away from and close to the rotation axis and the part between the two sides are connected to an outer wall, an inner wall, and a middle wall, respectively, the outer wall, the inner wall, and the middle wall protrude in the second direction and are connected to a barrier wall between the outer wall and the inner wall; a support surface is formed between the main wall and the outer wall.

[0006] A steel cable through-hole is formed between the main wall, the inner wall, the middle wall, and the baffle wall; an elastic ring through-hole is formed between the main wall, the outer wall, the middle wall, and the baffle wall. A placement inlet is formed on the baffle wall corresponding to the portion of the elastic ring through-hole. The placement inlet penetrates the baffle wall along the rotation direction of the rotation axis, and the length of the placement inlet perpendicular to the rotation axis is less than the length of the elastic ring through-hole perpendicular to the rotation axis. The retaining ring is an elastic body and is tightly fitted around the multiple retaining ring grooves of the multiple support elements. The steel cable ring passes through the multiple steel cable through-holes of the multiple support elements. The elastic ring passes through and is embedded in the multiple elastic ring through-holes of the multiple support elements. The elastic ring is an elastic body and, after being compressed and deformed by external force, can pass through the multiple placement inlets of the multiple support elements.

[0007] In use, the hooks of the plurality of support elements are engaged with the main wall to fasten to a convex ring formed on the inner sidewall of a tire, thereby fixing the tire burst protection device to the inner sidewall of the tire. At this time, there is a certain length of gap between the support surface of each support element of the tire burst protection device and the tread of the tire, so that even if the tread is temporarily deformed by running over an object when the tire is in normal use, the tread will not collide with the tire burst protection device.

[0008] The advantage of this invention is that when a tire blows out and loses pressure, causing the tread to collapse inward, the multiple support elements are arranged in a circular pattern by the retaining ring, the steel cable ring, and the elastic ring. Furthermore, the multiple support elements can be placed side-by-side in pairs. At this time, the support surfaces of the multiple support elements fixed to the inner sidewall of the tire can support the tread, allowing the tire to maintain a certain shape and continue rolling, thus preventing the vehicle from losing control. Moreover, the blowout recovery device provides tire support force, enabling the vehicle to be safely moved to the roadside to await rescue, or allowing the vehicle to continue driving until it reaches the nearest repair shop.

[0065] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figures 1 to 5 As shown, a tire blowout recovery device 100 according to a preferred embodiment of the present invention is used to install on a tire and includes a plurality of support elements 10, a bundle of rings 20, a steel cable ring 30, and an elastic ring 40 that fix the plurality of support elements 10 in a circular arrangement about a rotation axis L. The two opposite directions along the rotation axis L are defined as a first direction L1 and a second direction L2, wherein:

[0066] The plurality of support elements 10 includes thirty support elements 10. Each support element 10 is made of polyvinyl chloride (PVC), commonly known as plastic steel, and is bent into an arc shape. In other preferred embodiments, the plurality of support elements 10 may include two or more other numbers of support elements 10. Each support element 10 may also be made of materials such as aluminum alloy, carbon fiber, or glass fiber. The plurality of support elements 10 are adjacent to each other. Each support element 10 has a main wall 12, which is an arc-shaped plate and has a hook portion 14 connected to the side away from the rotation axis L. The hook portion 14 protrudes towards the first direction L1 and has a suspended end 141. The portion of the hook portion 14 adjacent to the suspended end 141 has a binding ring groove 142. The plurality of hook portions 14 of the plurality of support elements 10 are arranged in a circle around the rotation axis L, and the plurality of binding ring grooves 142 of the plurality of support elements 10 are also arranged in a circle around the rotation axis L.

[0067] Please refer to Figures 2 to 4 and Figure 7 , Figure 8 As shown, the main wall 12 is connected to an outer wall 16 on one side away from the rotation axis L and an inner wall 18 on the other side. A middle wall 11 connects to the portion of the main wall 12 located between the outer wall 16 and the inner wall 18. The multiple outer walls 16, inner walls 18, and middle walls 11 of the multiple support elements 10 are arranged in a circle around the rotation axis L. The outer walls 16, inner walls 18, and middle walls 11 are plates protruding from the main wall 12 towards the second direction L2. A baffle 13 connects between the outer walls 16 and inner walls 18, and the baffle 13 is also connected to the middle wall 11. A steel cable perforation 15 is formed between the main wall 12, inner walls 18, middle walls 11, and baffle 13; an elastic ring perforation 17 is formed between the main wall 12, outer walls 16, middle walls 11, and baffle 13.

[0068] The plurality of cable perforations 15 of the plurality of support elements 10 are arranged in a circular pattern around the rotation axis L; the plurality of elastic ring perforations 17 of the plurality of support elements 10 are also arranged in a circular pattern around the rotation axis L. A portion of the baffle wall 13 corresponding to the elastic ring perforation 17 forms an insertion inlet 131, which penetrates the baffle wall 13 along the rotation direction of the rotation axis L, and the length of the insertion inlet 131 perpendicular to the rotation axis L is less than the length of the elastic ring perforation 17 perpendicular to the rotation axis L.

[0069] The inlet 131 expands at both ends along the rotational direction of the rotation axis L to form a first semi-expanded region 132 and a second semi-expanded region 133, respectively. The first semi-expanded region 132 of one of two adjacent support elements 10 faces the second semi-expanded region 133 of the other support element 10, and multiple pairs of opposing first semi-expanded regions 132 and second semi-expanded regions 133 exist between the plurality of support elements 10. In this preferred embodiment, the first semi-expanded region 132 communicates not only with the elastic ring through-hole 17, but also with both the steel cable through-hole 15 and the elastic ring through-hole 17; similarly, the second semi-expanded region 133 communicates not only with the elastic ring through-hole 17, but also with both the steel cable through-hole 15 and the elastic ring through-hole 17.

[0070] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, the main wall 12 and outer wall 16 of each support element 10 form a support surface F on their sides away from the rotation axis L. Each support element 10 has a first end face F1 and a second end face F2 at its two ends along the rotation direction of the rotation axis L. A first protrusion 191 and a second protrusion 192 are formed on the sides of the first end face F1 away from and near the rotation axis L, respectively, and the first protrusion 191 and the second protrusion 192 protrude from the first end face F1. Specifically, the diameter of the first protrusion 191 is larger than the diameter of the second protrusion 192. Each first protrusion 191 is located on the portion of the main wall 12 connecting the hook portion 14 and the outer wall 16, and each second protrusion 192 is located on the portion of the main wall 12 connecting the middle wall 11. The first protrusion 191 also has a socket 193. See also... Figure 9 and Figure 10 As shown, an adjustment member 19 can be selectively inserted into the socket 193. When the adjustment member 19 is an elastic body and when the adjustment member 19 is inserted into the socket 193, the adjustment member 19 protrudes from the first protrusion 191.

[0071] Normally, the first protrusion 191 and the second protrusion 192 of one of two adjacent support elements 10 are used to abut against the second end face F2 of the other support element 10. When the gap between a plurality of adjacent support elements 10 is too large, the adjusting member 19 can be inserted into the insertion hole 193 of one of the support elements 10. By having the adjusting member 19 cooperate with the second protrusion 192 to abut against the second end face F2 of the other support element 10, the gap between the adjacent support elements 10 is filled, so that the plurality of support elements 10 can be arranged in a more compact manner.

[0072] Please refer to Figures 1 to 4 As shown, the retaining ring 20 is an annular elastic body that tightly surrounds the plurality of retaining ring grooves 142 of the plurality of support elements 10. Through the restoring force of the retaining ring 20, the retaining ring 20 can bind the plurality of support elements 10 into a pair-together state, as described above, where the first protrusion 191 and the second protrusion 192 of one of two adjacent support elements 10 abut against the second end face F2 of the other support element 10.

[0073] Please refer to Figure 2A and Figures 7 to 8BAs shown, the steel cable ring 30 includes a steel cable 32 and a steel cable adjustment component 34. The steel cable 32 passes through the plurality of steel cable through holes 15 of the plurality of support elements 10, and both ends of the steel cable 32 are respectively connected to a sleeve 321. Each sleeve 321 has a screw hole 322, and each screw hole 322 is coaxially disposed in the sleeve 321. Each sleeve 321 has a positioning screw hole 323 around its periphery, and each positioning screw hole 323 communicates with one side of the periphery of each screw hole 322. A positioning bolt 324 is screwed into each positioning screw hole 323. The steel cable adjusting member 34 has a rotating member 341; in this preferred embodiment, the rotating member 341 is a polygonal prism, and each end of the rotating member 341 has a screw 342, the threads of the two screws 342 are opposite, each screw 342 is screwed into the screw hole 322 of each sleeve 321, and one side of each screw 342 is abutted by each positioning bolt 324, thereby fixing the position of each screw 342 with each positioning bolt 324. The rotating member 341 is exposed outward from one of the pair of opposing first semi-enlarged areas 132 and second semi-enlarged areas 133. Therefore, after loosening each of the positioning bolts 324, the user can tighten or loosen the steel cable 32 by rotating the rotating component 341. After adjusting the steel cable adjusting component 34, the user can retighten each of the positioning bolts 324 to fix the length of the steel cable loop 30 and prevent the tension of the steel cable 32 from loosening. When the steel cable adjusting component 34 tightens the steel cable 32, the steel cable 32 will be pressed against the inner wall of the steel cable through hole 15, and the steel cable 32 will bind the multiple support elements 10 into a pair-by-pair state.

[0074] Please refer to Figure 2A , Figure 4 , Figure 5 and Figure 7 As shown, the elastic ring 40 is an elastic body such as rubber or plastic that can deform and return to its original shape after being compressed by external force. The elastic ring 40 passes through and is embedded in the multiple elastic ring through holes 17 of the multiple support elements 10. After being compressed and deformed by external force, the elastic ring 40 can pass through the multiple insertion ports 131 of the multiple support elements 10, so that the elastic ring 40 can be inserted into the multiple elastic ring through holes 17 of the multiple support elements 10 through the multiple insertion ports 131, or moved outward from the multiple elastic ring through holes 17 of the multiple support elements 10. The elastic ring 40 can constrain the multiple support elements 10 into a state of two adjacent to each other.

[0075] When using the above preferred embodiments of the present invention, please refer to... Figure 7 and Figure 11As shown, the tire blowout recovery device 100 is installed on a tire 50. The tire 50 has a tread 51 and a sidewall 52 connected to the tire 50. A protruding ring 53 is provided on the inner side of the base of the sidewall 52 towards the tread 51. When the tire blowout recovery device 100 is installed on the tire 50, the hooks 14 of the plurality of support elements 10 are fastened to the sidewall 52 in conjunction with the main wall 12. The plurality of support elements 10 are constrained into a circular arrangement by the clamping ring 20, the steel cable ring 30, and the elastic ring 40. In addition, the plurality of support elements 10 are in a state of two-by-two contact after being constrained, so that when the tire 50 blows out and loses pressure, the tread 51 collapses inward, and the tread 51 collapses inward. When pressure is applied to the tire blowout recovery device 100, the plurality of support elements 10 of the tire blowout recovery device 100 can maintain a circular arrangement, and the tread 51 of the tire 50 is supported by each support surface F of the plurality of support elements 10, so that the tire 50 supported by the tire blowout recovery device 100 can still maintain a rolling state after being damaged and leaking air, avoiding the situation of losing vehicle control, and allowing the vehicle to continue driving to the side of the road to stop, or to a repair shop for repair or tire replacement.
