[0032] In the description of the present utility model, it should be understood that the terms "first", "second", etc. used in the present utility model to describe various information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0033] Such as Figures 1 to 6As shown in the figure, an embodiment of the present utility model provides a wheel hub 100, specifically a wheel hub 100 for a skateboard, which includes a rim 30, a first retaining ring 10, and a second retaining ring 20. The rim 30 has a first mounting portion 31 and a second mounting portion 32; the first mounting portion 31 and the second mounting portion 32 are respectively arranged on opposite sides of the rim 30; the first retaining ring 10 is sleeved on the first mounting portion 31 and is snap-connected to the first mounting portion 31; the second retaining ring 20 is sleeved on the second mounting portion 32 and is fixedly connected to the second mounting portion 32; wherein, the rim 30, the first retaining ring 10, and the second retaining ring 20 are all made of metal materials.

[0034] Based on the above technical solution, the first retaining ring 10 is sleeved on the first mounting portion 31 to be installed on the outer side of the rim 30, and the second retaining ring 20 is sleeved on the second mounting portion 32 to be installed on the inner side of the rim 30. The area enclosed by the first retaining ring 10, the second retaining ring 20, and the rim 30 is used for installing a tire. When the tire needs to be disassembled and replaced due to a fault, since the first retaining ring 10 is snap-connected to the first mounting portion 31, only an external force needs to be applied to release the connection between the first retaining ring 10 and the first mounting portion 31, and the tire can be taken out. Compared with the structure of using screws to fix the retaining ring, in this embodiment, the first retaining ring 10 is designed to be snap-connected to the first mounting portion 31, so as to facilitate the disassembly of the first retaining ring 10 and the tire, thereby reducing the difficulty of installing and disassembling the tire and improving the efficiency of replacing the tire.

[0035] In the related art, the wheel hub 100 is made of plastic material and is relatively easy to break. In this embodiment, the rim 30, the first retaining ring 10, and the second retaining ring 20 are all made of metal materials, that is, the whole wheel hub 100 is made of metal material to improve the structural strength of the wheel hub 100.

[0036] Exemplarily, the first retaining ring 10, the second retaining ring 20, and the rim 30 are all made of lightweight and high-strength aluminum alloy material, which can reduce the overall weight while improving the structural strength.

[0037] In some embodiments, as Figures 3 to 6 shown, the first mounting portion 31 is provided with a plurality of clamping members 310 along the circumferential direction, and the first retaining ring 10 is provided with a plurality of clamping grooves 101 along the circumferential direction. Each clamping member 310 is respectively snapped into each clamping groove 101 to enable the first retaining ring 10 to be snap-connected to the first mounting portion 31.

[0038] Specifically, a plurality of clamping members 310 are circumferentially distributed along the edge of the first mounting portion 31 of the rim 30. Along the circumference of the first retaining ring 10, a number of clamping grooves 101 equal to the number of the clamping members 310 are provided. The shape and size of the clamping grooves 101 match those of the clamping members 310, and the two can be tightly fastened together. During installation, align the first retaining ring 10 with the first mounting portion 31, and by gently rotating or pressing, insert each clamping member 310 into the corresponding clamping groove 101 one by one to form a tight locking state after being inserted into the groove position.

[0039] In the design of skateboard wheels, the distribution of the snap structure is crucial for the balance of the wheels. Uneven spacing distribution leads to uneven stress, affecting the connection strength and the stability of the wheels.

[0040] In some embodiments, as Figure 5 and Figure 6 shown, a plurality of clamping members 310 are circumferentially equally spaced, and a plurality of clamping grooves 101 are circumferentially equally spaced.

[0041] Specifically, a plurality of clamping members 310 are circumferentially equally spaced along their circumferences, and a plurality of clamping grooves 101 are circumferentially equally spaced along their circumferences. Each clamping member 310 is inserted into the corresponding clamping groove 101 one by one and equally spaced. This equally spaced distribution method makes the installation process smoother and at the same time ensures the stability of the snap connection between the first retaining ring 10 and the first mounting portion 31.

[0042] In some embodiments, as Figure 3 and Figure 4 shown, the clamping members 310 are provided on the outer wall of the first mounting portion 31, and the clamping grooves 101 are provided on the inner wall of the first retaining ring 10.

[0043] Specifically, on the outer wall of the first mounting portion 31, a plurality of clamping members 310 are circumferentially equally spaced. These clamping members 310 can be outwardly protruding elastic protrusions, hook-shaped structures or other shapes, which are used to cooperate with the clamping grooves 101 on the inner wall of the first retaining ring 10 to achieve a stable connection. On the inner wall of the first retaining ring 10, a plurality of clamping grooves 101 are provided at positions corresponding to the clamping members 310. The shape, size and depth of the clamping grooves 101 match those of the clamping members 310.

[0044] During actual production, a suitable aluminum alloy or other lightweight and high-strength metal material is selected, and the wheel rim 30, the first retaining ring 10, and the second retaining ring 20 are processed by means of casting, forging, or machining. A plurality of equally spaced engaging members 310 are machined on the outer wall of the first mounting portion 31, and an engaging groove 101 matching the engaging members 310 is machined on the inner wall of the first retaining ring 10. Align the first retaining ring 10 with the first mounting portion 31 to ensure that they are on the same axis, and then gently rotate or press the first retaining ring 10 so that its inner wall fits tightly against the outer wall of the first mounting portion 31. At the same time, check whether each engaging member 310 has been accurately snapped into the corresponding engaging groove 101.

[0045] In some embodiments, as Figure 6 shown, the first retaining ring 10 includes a first ring body 11 and a second ring body 12 connecting the first ring body 11. The outer diameter of the second ring body 12 is larger than the outer diameter of the first ring body 11. The first ring body 11 is sleeved on one side of the first mounting portion 31 close to the second mounting portion 32, and the engaging groove 101 is provided on the inner wall of the second ring body 12.

[0046] Specifically, the outer diameter of the second ring body 12 is larger than the outer diameter of the first ring body 11, forming a stepped ring body structure. The first ring body 11 is sleeved inside the first mounting portion 31, and the second ring body 12 is sleeved outside the first mounting portion 31. During installation, align the first ring body 11 of the first retaining ring 10 with the first mounting portion 31, push it inward and gently rotate or press it until it is sleeved in place, until the engaging member 310 on the first mounting portion 31 snaps into the engaging groove 101 on the inner wall of the second ring body 12.

[0047] In some embodiments, as Figure 6 shown, the first ring body 11 and the second ring body 12 are of an integrally formed structure. The two ring bodies are integrally manufactured, which is beneficial for rapid production.

[0048] In some embodiments, as Figure 1 and Figure 2 shown, an installation hole 33 is provided at the center of the wheel rim 30. A bearing is installed in the installation hole 33, and the bearing of the hub 100 is installed on the rotating shaft of the skateboard. Vent holes 34 are provided on the side wall of the wheel rim 30. The vent holes 34 communicate with the air holes on the inner tube of the tire, and the tire can be inflated through the vent holes 34. In addition, the vent holes 34 are also equipped with sealing devices such as sealing plugs or valve nozzles to ensure that the tire can maintain a sealed state.

[0049] In some embodiments, as Figure 1 and Figure 2 shown, from both sides of the wheel rim 30 to the central axis direction of the first mounting portion 31 and the second mounting portion 32, the wheel rim 30 gradually depresses towards the center of the wheel rim 30.

[0050] Specifically, starting from the two side edges of the rim 30, it gradually deepens along the direction towards the center of the rim 30 until it reaches near the central axis of the first mounting portion 31 and the second mounting portion 32, and the depression reaches the maximum depth to form a depression structure, so that during the tire mounting process, the bead of the tire can more easily slide into the rim 30 while ensuring a sealed contact between the tire edge and the rim 30.

[0051] In this embodiment, the tires of the skateboard are off-road tires. The off-road tires have deeper treads and softer rubber, enabling the tires to provide better grip on complex road surfaces. Compared with ordinary skateboard wheels, off-road tires can reduce slipping and improve the stability and safety of skateboard sliding.

[0052] In a second aspect, the present utility model provides a wheel, specifically a wheel of a skateboard, which includes a tire and a hub 100, and the hub 100 is used to support the tire.

[0053] Specifically, by adopting the above-mentioned hub 100, the first retaining ring 10 is designed to be snap-connected to the first mounting portion 31 for easy disassembly and replacement of the tire.

[0054] In a third aspect, the present utility model provides a skateboard, which includes a pedal and a plurality of wheels, and the plurality of wheels are used to support the pedal.

[0055] Specifically, the pedal is made of a lightweight and high-strength composite material, such as carbon fiber, aluminum alloy or fiberglass, etc., to ensure that the skateboard has sufficient strength and stiffness while maintaining light weight. The shape of the pedal is designed according to ergonomics, facilitating the skater to stand and perform various actions. The wheels adopt the above-mentioned wheel structure with enhanced performance, including a high-strength hub and wear-resistant and highly elastic tires, to ensure that the skateboard can maintain good sliding performance and stability under different road conditions.
