Description

Technical Field

[0001] This utility model belongs to the field of wheel hub technology, and in particular relates to wheel hubs for puncture-proof tires. Background Technology

[0002] A wheel hub is the rotating part of the tire's inner rim, connected to the wheel core by a pillar; it's the central metal component supporting the tire and mounted on the axle. It's also called a wheel rim, steel rim, wheel, or tire rim. Wheel hubs come in many varieties depending on their diameter, width, molding method, and materials.

[0003] According to CN222522382U, a puncture-resistant tire hub includes a main body. A spoked wheel is fixedly connected to the inside of one side of the main body. The main body has a head at one end, a middle section in the middle, and a tail at the other end. The head, middle section, and tail are an integrated structure. Several protruding ribs are fixedly connected to the inner wall of the main body. This utility model increases structural strength through the stepped design of the head, reduces the thickness of the middle section, optimizes material distribution, and facilitates quick installation and removal of the puncture-resistant tire through the b-angle connection between the head and the middle section. The rounded transition design of the b-angle between the tail and the middle section enhances structural strength, reduces material redundancy, and increases the stability of the device. The integrated design of the head, middle section, and tail makes the entire hub structure more compact, reduces structural material usage, and increases material utilization to over 90%. However, when the puncture-resistant tire is punctured and loses pressure, relying solely on the thicker inner side of the tire to support vehicle operation cannot guarantee tire stability and needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide a rim for puncture-proof tires. By pressing an elastic block with a retaining ring, the wave-shaped support structure of the elastic block forms a spring-like structure, providing support, cushioning, and guidance. The elastic block drives the retaining ring to hold the inner wall of the tire body, providing auxiliary support for the tire. Furthermore, the sealing boss at the junction of the tire and the rim improves the sealing performance, preventing the tire from detaching from the rim and ensuring the stability of the tire when pressure is lost, thus solving the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a puncture-proof tire hub, comprising a hub body, a rim on the outer side of the hub body, a tire body on the outer side of the rim, a mounting plate on one side of the hub body, a connecting plate on one side of the mounting plate, spokes on the outer side of the connecting plate, a bead seat on the inner side of the rim, a protrusion on the outer edge of the rim, a rim groove on the inner side of the rim, and a limiting component inside the rim groove; The limiting component includes a positioning groove inside the rim groove, a fixing ring inside the positioning groove, an elastic block outside the fixing ring, and a retaining ring outside the elastic block.

[0006] Furthermore, the inner wall surface of one end of the hub body is provided with raised ribs, which are arranged in a ring and two are arranged symmetrically.

[0007] Furthermore, the wheel spokes are provided in a plurality of numbers, the wheel spokes are distributed in a ring array, a reinforcing rib is provided on one side of the wheel spokes, and a plurality of the reinforcing ribs are arranged radially, the reinforcing ribs being fin-shaped.

[0008] Furthermore, the number of elastic blocks is set to several, the elastic blocks are distributed in a circular array, and the elastic blocks are in a wave shape.

[0009] Furthermore, the fixing ring is adapted to the size of the positioning groove, and the fixing ring is engaged with the rim groove through the positioning groove.

[0010] Furthermore, the size of the retaining ring is adapted to the internal dimensions of the tire body, and the retaining ring is movably connected to the fixing ring through an elastic block.

[0011] This utility model has the following beneficial effects: By setting up a ring of raised ribs, with two symmetrically arranged raised ribs, the ring-shaped raised ribs enhance the circumferential strength of the rim itself and resist deformation. The number of spokes is set up in a ring array, with a reinforcing rib on one side of the spokes. Several reinforcing ribs are arranged radially, and the reinforcing ribs are fin-shaped. The fin-shaped ribs, together with the radially arranged reinforcing ribs, increase the effective heat dissipation area and airflow channels while improving strength, thereby improving heat dissipation efficiency.

[0012] By setting a wave-shaped elastic block with a retaining ring on the outside, the retaining ring abuts against the inside of the tire body. When the tire is punctured and loses pressure, the tire deforms and contracts, causing the retaining ring to squeeze the elastic block. The wave-shaped support structure of the elastic block forms a spring-like structure, providing support, cushioning, and guidance. The elastic block drives the retaining ring to hold against the inner wall of the tire body, providing auxiliary support for the tire. In addition, the sealing boss at the junction of the tire and the rim improves the sealing performance, preventing the tire from detaching from the rim and ensuring the stability of the tire when pressure is lost.

The raised rib 101 is arranged in a ring, and two raised ribs 101 are symmetrically arranged. The ring-shaped raised rib 101 enhances the circumferential strength of the rim 2 itself and resists deformation. The number of spokes 6 is provided in a ring array. A reinforcing rib 601 is provided on one side of the spokes 6. The reinforcing ribs 601 are arranged radially. The reinforcing ribs 601 are fin-shaped. The fin shape combined with the radial layout of the reinforcing ribs 601 increases the effective heat dissipation area and airflow channel while improving the strength, thereby improving the heat dissipation efficiency.

[0019] Please see Figure 3-4 In this embodiment, the limiting component 10 includes a positioning groove 1001 disposed inside the rim groove 9, a fixing ring 1002 disposed inside the positioning groove 1001, an elastic block 1003 disposed outside the fixing ring 1002, and a retaining ring 1004 disposed outside the elastic block 1003.

It works with the sealing boss at the junction of the tire and the rim to improve the sealing performance, prevent the tire from coming off the rim, and ensure the stability of the tire when pressure is lost.

[0020] One specific application of this embodiment is as follows: In use, when the puncture-proof tire is punctured and loses pressure, the tire deforms. Due to its thick sidewall, it can continue to provide support. During deformation, the compression of the retaining ring 1004 presses against the elastic block 1003, which takes on a wave shape. This wave-shaped support structure forms a spring-like structure, providing support, cushioning, and guidance. The elastic block 1003 drives the retaining ring 1004 to abut against the inner wall of the tire body 3, providing auxiliary support for the tire. Furthermore, the sealing boss at the junction of the tire and the rim improves the sealing performance, preventing the tire from detaching from the rim and ensuring the tire's stability during pressure loss. The stability is enhanced by the presence of raised ribs 101 on the inner wall surface of one end of the hub body 1. The raised ribs 101 are arranged in a ring, and there are two symmetrical raised ribs 101. The ring-shaped raised ribs 101 enhance the circumferential strength of the rim 2 itself and resist deformation. The spokes 6 are arranged in a ring array. A reinforcing rib 601 is provided on one side of the spokes 6. The reinforcing ribs 601 are arranged radially and are fin-shaped. The fin shape combined with the radial layout of the reinforcing ribs 601 increases the effective heat dissipation area and airflow channels while improving strength, thereby improving heat dissipation efficiency.
