Description

Technical Field

[0001] The utility model relates to the technical field of wheels, in particular to a double-hardness wheel. Background Art

[0002] There are many styles of wheels for scooters and skates used for playing and traveling. Common scooter wheels include a wheel body and a hub. The hub is mounted on the axle through a ball bearing, and the wheel body is arranged on the outer ring of the hub to constitute a wheel.

[0003] The wheels of existing skateboards or roller skates mostly use a single-layer wheel structure and are mostly made of polyurethane. The structural design of the single-layer wheel makes it difficult for the wheels to simultaneously obtain good support and deformation capabilities. The poor light transmittance of the polyurethane material makes it impossible to install traditional light-emitting components on the wheel shell.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a dual-hardness wheel is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a dual-hardness wheel to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dual-hardness wheel, comprising a wheel hub and an axle hole, wherein the wheel hub is provided with an axle hole through the middle part thereof, and a center wheel meat is provided in the middle part of the outer circumference of the wheel hub, and the center wheel meat is in an inverted trapezoidal structure, and edge wheel meat is provided on both sides of the outer circumference of the wheel hub, and the edge wheel meat is in an inverted triangular structure, the center wheel meat and the edge wheel meat are both made of polyurethane, and the hardness of the center wheel meat is greater than the hardness of the edge wheel meat on both sides.

[0007] Furthermore, a shaft rod is provided through the middle of the wheel axle hole, and a mounting nut is threadedly fixed on the end of the shaft rod.

[0008] Furthermore, a magnetic ring is tightly fitted in the middle of the shaft, and bearings are symmetrically arranged on both sides of the magnetic ring.

[0009] Furthermore, the outer diameter of the bearing is larger than the outer diameter of the magnetic ring, and the bearing, the magnetic ring and the shaft are coaxially arranged.

[0010] Furthermore, the outside of the bearing is tightly fitted with the generator coil, and the inner wall of the generator coil does not contact the outer wall of the magnetic ring.

[0011] Furthermore, a limiting sleeve is integrally fixed in the middle of the power generation coil, and LED lamp beads are arranged in a circular array on the side of the power generation coil.

[0012] Furthermore, a dust cover is engaged with the outer side of the generating coil, and a side surface of the dust cover is provided with a through hole corresponding to the LED lamp bead.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the present invention is in use, the dual-hardness wheel of the present application is designed with the center wheel flesh located in the middle of the outer circumference of the hub, and the edge wheel flesh located on both sides of the outer circumference of the hub. Both the center wheel flesh and the edge wheel flesh are made of polyurethane material, and the hardness of the center wheel flesh is greater than the hardness of the edge wheel flesh on both sides. The high-hardness center wheel flesh can provide better support when driving in a straight line, and the low-hardness edge wheel flesh can produce a certain deformation when performing skill movements, thereby obtaining a good foot feel and stronger applicability.

[0015] 2. When the present invention is in use, when the generating coil is located outside the shaft through the bearings on both sides and rotates, since the inner wall of the generating coil is not in contact with the outer wall of the magnetic ring, electricity can be generated through relative rotation to power the LED lamp beads for illumination. The LED lamp beads are exposed to the outside of the wheel hub through the perforations opened on the side of the dust cover. They can illuminate themselves during the rotation of the wheel without an external battery, producing a gorgeous use effect. At the same time, the dust cover can prevent dust and rain from invading the interior of the wheel hub, thereby extending the service life of the generating components. By arranging the LED lamp beads on the side of the wheel hub, the present application effectively solves the existing technical deficiency that the light-emitting components cannot be installed on the outer skin of the wheel due to the low transparency of the polyurethane wheel.

When designing the dual-hardness wheel of the present application, the center wheel meat 3 is located in the middle of the outer circumference of the hub 1, and the edge wheel meat 4 is located on both sides of the outer circumference of the hub 1, the center wheel meat 3 and the edge wheel meat 4 are both made of polyurethane, and the hardness of the center wheel meat 3 is greater than the hardness of the edge wheel meat 4 on both sides, wherein the high-hardness center wheel meat 3 can provide better support when driving in a straight line, and the low-hardness edge wheel meat 4 can produce a certain deformation when performing skill movements, thereby obtaining a good foot feel;

[0022] like Figures 1 to 2 As shown, a shaft rod 5 is provided through the middle of the wheel axle hole 2, and a mounting nut 6 is fixed by thread on the end of the shaft rod 5, a magnetic ring 7 is tightly fitted in the middle of the shaft rod 5, and bearings 8 are symmetrically provided on both sides of the magnetic ring 7, the outer diameter of the bearing 8 is larger than the outer diameter of the magnetic ring 7, and the bearing 8, the magnetic ring 7 and the shaft rod 5 are coaxially arranged, the outside of the bearing 8 is tightly fitted with the power generation coil 9, and the inner wall of the power generation coil 9 does not contact the outer wall of the magnetic ring 7, the middle of the power generation coil 9 is integrally fixed with a limiting sleeve 10, and LED lamp beads 11 are provided in a ring array on the side of the power generation coil 9, a dust cover 12 is engaged with the outside of the power generation coil 9, and a through hole 13 corresponding to the LED lamp bead 11 is provided on the side of the dust cover 12. When the bearings 8 on both sides are located outside the shaft 5 and rotate, since the inner wall of the generating coil 9 is not in contact with the outer wall of the magnetic ring 7, electricity can be generated through relative rotation to power the LED lamp beads 11 for illumination. The LED lamp beads 11 are exposed to the outside of the wheel hub 1 through the through holes 13 opened on the side of the dust cover 12. They can emit light by themselves during the rotation of the wheel without an external battery, producing a gorgeous use effect.

The high-hardness center wheel meat 3 can provide better support when driving in a straight line, and the low-hardness edge wheel meat 4 can produce a certain deformation when performing skill movements, thereby obtaining a good foot feel. During use, when the generating coil 9 is located outside the shaft 5 through the bearings 8 on both sides and rotates, because the inner wall of the generating coil 9 does not contact the outer wall of the magnetic ring 7, the relative rotation can generate electrical energy to power the LED lamp beads 11 for illumination.

Without an external battery, it can emit light by itself during the rotation of the wheel, producing a gorgeous use effect.
