Description

Technical Field

[0001] This utility model relates to the field of children's vehicle tire technology, specifically an explosion-proof children's vehicle tire. Background Technology

[0002] Existing children's bicycle wheels typically consist of an inner and outer tire, both of which are key structural elements ensuring the bicycle's proper functioning. The outer tire, in direct contact with the ground, is usually made of durable rubber with a tread pattern to enhance grip and cushion impacts. The inner tire, housed inside the outer tire, is also made of elastic rubber and is used for inflation to maintain tire shape and pressure, resulting in a smoother ride. The inner and outer tires work together to provide stable support and good shock absorption for the bicycle.

[0003] The aforementioned inner and outer tire technologies have the problem of being prone to blowouts during use. Specifically, when the tire is over-inflated, the internal pressure becomes too high, much like an over-blown balloon that is prone to bursting. Bumps or impacts during driving can cause the inner tire to rupture. Conversely, when the tire is under-inflated, the increased friction between the inner tire and the rim and outer tire generates heat, causing the inner tire to soften and weaken, also making it prone to blowout. Once a blowout occurs, the child may fall due to sudden loss of balance, resulting in abrasions, sprains, or even fractures. Furthermore, the impact of a blowout can frighten the child, affecting their sense of security. If a blowout occurs on the road, it can also cause traffic accidents. Therefore, to address these issues, a blowout-proof children's stroller tire is proposed. Utility Model Content

[0004] To address the technical problem that current children's stroller tires lack strong structural performance and are prone to sudden blowouts due to air pressure or impacts, this utility model provides an explosion-proof children's stroller tire.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] An explosion-proof children's stroller tire includes a rim with a mounting groove for mounting the tire; the tire includes a carcass with an inflatable cavity inside, and a sealing rubber layer is bonded to the inner wall of the carcass; an explosion-proof mesh cage is embedded inside the carcass and includes two symmetrically arranged hoop wires connected to it with a plurality of cords arranged in a circular array, the cords being arranged perpendicular to the tire's rolling direction, and connecting lines being connected to the cords perpendicular to the cords.

[0007] In one possible implementation, the tire body has an integral anti-slip protrusion on both sides of its bottom, and the rim has an anti-slip groove that matches the size of the anti-slip protrusion.

[0008] In one possible implementation, the hoop is embedded in the end of the anti-detachment protrusion, and the anti-detachment protrusion is spatially arranged to be completely embedded in the anti-detachment groove.

[0009] In one possible implementation, both ends of the cord are bent and extended into the anti-detachment protrusion, and the ends of the cord are processed to form connecting hooks, which are snapped onto the hoop cord.

[0010] In one possible implementation, the connecting lines are all embedded in the adhesive layer, the lower end face of the adhesive layer is bonded to the cord, and the upper end face of the adhesive layer is bonded to the inner wall of the tire.

[0011] In one possible implementation, the bottom ends of both sides of the tire carcass are machined with pressing feet, the lower end face of which fits into the mounting groove of the rim, and the upper end face of which is machined with an inclined chamfer.

[0012] In one possible implementation, the rim is provided with an integral air nozzle, which has an air hole inside that communicates with the inflation cavity, and the diameter of the air hole is smaller than the distance between the ends of the two pressing feet.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] This tire integrates the inner and outer tires by bonding a sealing rubber layer to the tire body. When the sealing rubber layer is punctured, the tire body and the sealing rubber layer can be subjected to the pressure of the gas together, so that the sealing rubber layer will not be torn by bearing the pressure impact alone. In addition, the elastic deformation ability of the sealing rubber layer itself will continue to contract after being punctured to reduce the hole, which can prevent gas from leaking out slowly and give children more reaction time.

[0015] To enhance the overall mechanical properties of the tire carcass and ensure that the tire carcass has strong load-bearing capacity and impact resistance, an explosion-proof mesh cage is installed inside the tire carcass. The mesh cage structure, which is formed by cords, hoop wires and connecting wires, can cover the entire tire carcass. The explosion-proof mesh cage distributes the tensile force, thereby significantly improving the tire carcass's performance under tension and enhancing the overall stress resistance of the tire carcass, making it less likely to burst under pressure due to severe local deformation.

[0016] In addition, the end of the tire carcass is equipped with an anti-detachment protrusion and a pressing foot. The anti-detachment protrusion is inserted into the anti-detachment groove of the rim. Under the action of air pressure, the anti-detachment protrusion can be tightly squeezed and locked in the anti-detachment groove, ensuring the airtightness of the tire carcass installation and preventing the tire carcass from detaching from the rim during movement. The pressing foot can fit tightly with the rim under the action of air pressure, further improving the airtightness of the tire carcass installation. Attached Figure Description

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0024] like Figure 1 - Figure 2 As shown, this embodiment provides an explosion-proof children's stroller tire, including a rim 1 with an installation groove for mounting a tire 2. The tire 2 includes a tire body 21 with an internal inflation cavity. A sealing rubber layer 24 is bonded to the inner wall of the tire body 21. By bonding the sealing rubber layer 24 to the tire body 21, the inner tube and outer tire are integrated together. When the sealing rubber layer 24 is punctured, the tire body 21 and the sealing rubber layer 24 are subjected to the pressure of the gas together, preventing the sealing rubber layer 24 from being torn due to the pressure impact alone. Furthermore, the elastic deformation capacity of the sealing rubber layer 24 will tend to contract after being punctured to reduce the hole size, thus preventing gas leakage and allowing children more reaction time.

[0025] To enhance the overall mechanical properties of the tire carcass 21 and ensure that the tire carcass 21 has strong load-bearing capacity and impact resistance, such as... Figure 2 - Figure 3As shown, the explosion-proof children's stroller tire provided in this embodiment also includes an explosion-proof mesh cage 3, which is embedded inside the tire body 21. It includes two symmetrically arranged hoop wires 33, on which are connected a plurality of cords 31 arranged in a circular array. The arrangement direction of the cords 31 is perpendicular to the rolling direction of the tire 2, and the cords 31 are connected to connecting lines 32, which are perpendicular to the cords 31. The cords 31, hoop wires 33 and connecting lines 32 form a mesh cage structure that can cover the entire tire body 21. The explosion-proof mesh cage 3 distributes the tensile force, thereby significantly improving the performance of the tire body 21 under tension, and enhancing the overall stress resistance of the tire body 21, making it less likely to experience local severe deformation and burst under pressure.

[0026] like Figure 2 - Figure 4 As shown, both sides of the bottom of the tire body 21 are provided with an integrated anti-detachment protrusion 22. The rim 1 is provided with an anti-detachment groove 11 that matches the size of the anti-detachment protrusion 22. The hoop 33 is embedded in the end of the anti-detachment protrusion 22. The anti-detachment protrusion 22 is completely embedded in the anti-detachment groove 11 in terms of spatial arrangement. Under the action of air pressure, the anti-detachment protrusion 22 can be tightly squeezed and locked in the anti-detachment groove 11, ensuring the sealing of the tire body 21 installation and making it difficult for the tire body 21 to detach from the rim 1 during movement. At the same time, under the action of air pressure, the hoop 33 will also be pressed into the anti-detachment groove 11, thereby establishing the force transmission relationship between the entire explosion-proof net cage 3 and the rim 1, and better transmitting the force on the tire body 21 to the rim 1.

[0027] Both ends of the cord 31 are bent and extended into the anti-detachment protrusion 22, and the ends of the cord 31 are processed to form connecting hooks 311, which are snapped onto the hoop cord 33. The above structure can realize the force transmission connection between the cord 31 and the hoop cord 33, and under the action of the external thrust of air pressure, the cord 31 can always be tightly connected to the hoop cord 33. In addition, the connecting lines 32 are embedded in the adhesive layer 34. The lower end face of the adhesive layer 34 is bonded to the cord 31, and the upper end face of the adhesive layer 34 is bonded to the inner wall of the tire carcass 21. The connection between the cord 31 and the connecting lines 32 can be realized through the adhesive layer 34, and the adhesive layer 34 can play the role of force transmission, so that the cord 31 and the connecting lines 32 can form a stable force transmission system through crisscrossing.

[0028] In addition, the bottom ends of both sides of the tire body 21 are machined with pressing feet 23, the lower end face of which fits into the mounting groove of the rim 1, and the upper end face is machined with an inclined chamfer. The pressing feet 23 can fit tightly into the rim 1 under air pressure, further improving the airtightness of the tire body 21 installation. In addition, the rim 1 is provided with an integrated air nozzle 4, which has an air hole inside that communicates with the inflation cavity. The diameter of the air hole is smaller than the distance between the ends of the two pressing feet 23. This size design ensures that the pressing feet 23 will not block the air hole, preventing the pressing feet 23 from being blown up when air is filled into the inflation cavity, which would prevent the tire body 21 from being sealed with the rim 1.

[0029] The working principle and usage process of this utility model:

[0030] Air is injected into the inflation cavity through the air nozzle 4. Under the action of air pressure, the anti-detachment protrusion 22 can be tightly squeezed and locked in the anti-detachment groove 11, ensuring the sealing of the tire body 21 installation and making it difficult for the tire body 21 to detach from the rim 1 during movement. At the same time, under the action of air pressure, the pressing foot 23 can fit tightly with the rim 1, further improving the airtightness of the tire body 21 installation.

[0031] When the sealing rubber layer 24 is punctured, the tire body 21 can be subjected to the pressure of the gas together with the sealing rubber layer 24, so that the sealing rubber layer 24 will not be torn due to the pressure impact alone. In addition, the elastic deformation ability of the sealing rubber layer 24 itself will continue to contract after being punctured to reduce the hole, which can block the gas leakage and allow the gas to leak slowly, giving the child a longer reaction time.

[0032] In addition, the cord 31, the hoop cord 33 and the connecting cord 32 can form a cage structure that can cover the entire tire body 21. The explosion-proof cage 3 shares the tensile force, thereby significantly improving the performance of the tire body 21 under tension and enhancing the overall stress resistance of the tire body 21, making it less likely to experience localized severe deformation and bursting under pressure.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
