[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0035] like Figures 1 to 4 As shown, a bearing-free luminous wheel comprises an inner sleeve 1, which is hollow and has a magnetic core 2 fixed on it; a generator core 3 is arranged outside the magnetic core 2, and a gap is reserved between the magnetic core 2 and the generator core 3. Figure 3 as well as Figure 4 It can be seen that the magnetic core 2 is mounted inside the generator core 3, so a gap is reserved between the two so that the two can rotate relative to each other to generate electricity.

[0036] The generator core 3 is installed and fixed in the wheel body, and the wheel body is provided with an assembly hole 503. In this embodiment, the wheel body includes a hub 5 and a tire 6 wrapped on the hub 5. The assembly hole 503 is provided on the hub 5, and the generator core 3 is fixed in the hub 5. When the inner sleeve 1, the magnetic core 2, and the generator core 3 are assembled into the hub 5, the inner sleeve 1 is located in the assembly hole 503. At the same time, the aperture of the assembly hole 503 is larger than the outer diameter of the inner sleeve 1, that is, there is a gap between the assembly hole 503 and the outer surface of the inner sleeve 1 so that the inner sleeve 1 does not affect the rotation of the hub 5. Therefore, the whole formed by the hub 5 and the tire 6 is rotatably assembled on the inner sleeve 1; when the luminous wheel moves, the generator core 3 rotates relative to the magnetic core 2, cuts the magnetic field formed by the magnetic core 2, forms a cutting magnetic line of force movement to generate electricity, and the generator core 3 is connected to the luminous lamp 4, and the electricity emitted by the generator core 3 is transmitted to the luminous lamp 4 for emission; the inner sleeve 1 can be made of metal materials such as iron or stainless steel to enhance wear resistance.

[0037] In this embodiment, the outer wall of the magnetic core 2 is wrapped with a magnetic ring, and the magnetic field formed by the magnetic ring radiates in all directions, which is helpful for the rotation cutting of the generator core 3.

[0038] like Figure 4 As shown, the wheel hub 5 is split, that is, it has a left half and a right half, and a fixing position 501 for limiting the light emitting lamp 4 is provided in the wheel hub 5; when installed in the wheel hub 5, the inner sleeve 1, the magnetic core 2, and the generator core 3 are sequentially sleeved and arranged from the inside to the outside; when the inner sleeve 1, the magnetic core 2, and the generator core 3 are installed in the wheel hub 5, the generator core 3 is first placed on one side of the wheel hub 5; then the magnetic core 2 is fixed on the inner sleeve 1 to form a whole, and then the whole is placed in the center of the generator core 3, forming a structure as shown in FIG. Figure 3 The assembled wheel hub 5 is placed in a mold for injection molding or pouring to form a tire 6. The tire 6 is made of a light-transmitting material, and the light of the light-emitting lamp 4 is emitted through the tire 6.

[0039] from Figure 4 It can be seen that the central axes of the inner sleeve 1, the magnetic core 2 and the generator core 3 coincide with each other, which helps to increase the amount of cutting of the magnetic lines of force of the magnetic core 2 when the generator core 3 rotates.

[0040] like Figures 5 to 9 As shown, the utility model also requests protection for a wheel frame device using the above-mentioned luminous wheel that does not require a bearing, including a wheel frame body 9 and a connecting long piece 10, the wheel frame body 9 is provided with a wheel frame hole 901, the connecting long piece 10 is connected in the wheel frame hole 901; the inner sleeve 1 is connected to the connecting long piece 10; the luminous wheel is fixed to the wheel frame body 9 by the connecting long piece 10.

[0041] During operation, the inner sleeve 1 must be fixed and not rotated, so that the generator core 3 can rotate relative to the inner sleeve 1 when the light-emitting wheel moves, thereby cutting the magnetic field formed by the magnetic core 2 on the inner sleeve 1 to generate current. In this structure, the inner sleeve 1 is fixed by connecting the long piece 10. The specific structure of the connecting long piece 10 can be in the following two ways:

[0042] As one of the implementation structures of the connecting long piece 10, the connecting long piece 10 is a metal tube. After the connecting long piece 10 is inserted into the inner sleeve 1, the end of the connecting long piece 10 is riveted to make the part Figure 8 The deformation shown is enlarged, and there is a pressing force on the inner sleeve 1 in the direction of the wheel frame body 9, so that the inner sleeve 1 is tightly pressed on the wheel frame body 9; the enlarged deformation also helps to limit the outer end of the inner sleeve 1, so that the inner sleeve 1 will not fall off.

[0043] As another implementation structure of the connecting long piece 10, the connecting long piece 10 is a mother-and-child rivet piece (the mother-and-child rivet piece is a mature component available on the market), including a long tube and a rivet. The rivet is threadedly connected to the long tube. When the rivet is screwed in, the side of the inner sleeve 1 is also pressed, so that the inner sleeve 1 has a pressing force toward the wheel frame body 9.

[0044] The two implementation structures of the above-mentioned connecting long piece 10 both achieve the purpose of fixing the inner sleeve 1 so that the magnetic core 2 does not rotate. When the light-emitting wheel moves, the generator core 3 will rotate relative to the magnetic core 2 to generate electricity.

[0045] Combination Figure 1 , Figure 2 as well as Fig.10It can be seen that a recess 502 is formed on the outer side of the wheel hub 5 at a location corresponding to the assembly hole 503, and the inner sleeve 1 is the outer surface of the recess 502 that protrudes outward, and a gasket 8 is arranged on the side of the inner sleeve 1. The purpose of the gasket 8 is that the part of the connecting long piece 10 that is deformed and enlarged during riveting or the rivet is directly pressed laterally on the gasket 8, and the gasket 8 helps to disperse the force; the inner sleeve 1 protrudes from the recess 502, so that the part of the connecting long piece 10 that is deformed and enlarged during riveting or the lateral pressure of the rivet is pressed on the inner sleeve 1, and will not be in contact with the recess 502, that is, it will not be pressed tightly on the wheel hub 5, and therefore will not affect the rotation of the wheel hub 5 relative to the inner sleeve 1.

[0046] The recessed portion 502 is detachably connected with a shielding cover 7, which is connected to the recessed portion 502 in a snap-fit ​​manner, and has a shielding effect on the connecting long piece 10, thereby enhancing the aesthetics.

[0047] The wheel frame body 9 is provided with a recessed position 902, and the wheel body is correspondingly provided with a boss 504. The boss 504 is rotatably assembled in the recessed position 902. The boss 504 and the recessed position 902 are used in combination to ensure that the side portion of the light-emitting wheel is rotationally confined in the recessed position 902, making the light-emitting wheel installation structure compact and not easy to loosen.

[0048] In this embodiment of the wheel frame body 9, there are two light-emitting wheels, which are connected to the connecting long piece 10 symmetrically with the wheel frame body 9 as the center.

[0049] Fig. 9 This is a schematic diagram of a wheel frame device according to an embodiment of the utility model having only one luminous wheel. In this embodiment, the inner sleeve 1 is pressed and does not rotate by the same riveting or screwing-in rivet method as above, so that the function of the luminous wheel moving and emitting light can be realized.

[0050] The utility model also seeks to protect a vehicle body, including the above-mentioned wheel frame device, wherein the vehicle body is a suitcase, a trolley case, a scooter, a toy car, a bicycle, a baby stroller, etc.

[0051] like Fig.10 as well as Fig.11 For example, it is a schematic diagram of another embodiment of the luminous wheel for which protection is sought in the present application; in this embodiment, a positioning ring 11 is used to replace the traditional bearing, and the positioning ring 11 is detachably embedded in the wheel body. During assembly, the inner sleeve 1 with the magnetic core 2 fixed thereon is placed in the center of the wheel body, and then the positioning ring 11 is installed, and the inner sleeve 1 is passed through the assembly hole 503 of the positioning ring 11; the fixing method of this luminous wheel is the same as that of the previous embodiment, that is, the inner sleeve 1 is fixed and does not rotate, and will not be described in detail here. The advantage of this structure is that the thickness of the positioning ring 11 can be set according to actual conditions, and a wheel body with a thin structure can also be produced, and the positioning ring 11 is simple to process and has a lower cost than a bearing, which is conducive to reducing the production cost of the wheel body.

[0052] exist Fig.12 In the figure, the edge of the positioning ring 11 is provided with a convex edge, and a groove is provided at the corresponding part of the wheel body. When the positioning ring 11 is installed into the wheel body, the convex edge is inserted into the groove, thereby limiting the positioning ring 11 from rotating relative to the wheel body, which helps to ensure the stability of the structure.

[0053] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
