[0023] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0024] The wheel structures of scooters, balance bikes, bicycles and other vehicles are designed in various forms to enhance aesthetics and user experience. In the related art, the wheel structure usually includes a tire, a hub, spokes, and a center axis, and various forms of spokes and hubs are connected to obtain the desired appearance. However, the wheels in the related art have complex structures and lack of technological sense due to the limitations of basic structures such as spokes.

[0025] The present disclosure provides a wheel, which is assembled with a frame, and includes a bearing bracket, a wheel hub, and at least one bearing. The bearing includes an outer ring and an inner ring, the outer ring is fixedly connected to the wheel hub, and the inner ring and the frame are respectively fixedly connected to the bearing bracket. The bearing bracket includes an inner surface facing the rotation center of the wheel, and the wheel also includes a hollow area surrounded by the inner surface.

[0026] Since the wheel includes a bearing bracket, a bearing and a wheel hub, the outer ring of the bearing is fixedly connected to the wheel hub, so that the wheel hub can rotate relative to the frame based on the fixed connection between the bearing bracket and the frame. The inner ring of the bearing is fixedly connected to the bearing bracket to achieve the support function of the bearing and other structures around the bearing through the bearing bracket. The wheel also includes a hollow area surrounded by the inner surface of the bearing bracket, so that the wheel has a hollow appearance, simplifies the wheel structure, and enhances the appearance and technological sense of the wheel. Because the wheel structure is simplified, the material usage and cost of the wheel are also reduced, reducing carbon emissions.

[0027] In the above embodiment, the above bearing may be one, two or more, and the present disclosure is not limited to this. The following takes the wheel including two bearings as an example to illustrate the wheel structure:

[0028] Figure 1 is a side structural schematic diagram of a wheel and a frame in cooperation in an exemplary embodiment of the present disclosure; Figure 2 is a schematic diagram of a three-dimensional structure of a wheel and a frame in cooperation with each other in an exemplary embodiment of the present disclosure; Figure 3 FIG. 1 is a schematic cross-sectional view of a wheel and a frame in an exemplary embodiment of the present disclosure. Figure 1 , Figure 2 , Figure 3 As shown, Figure 2 , Figure 3The dotted line represents the rotation center axis of the wheel 1. The wheel 1 is assembled with the frame 21, and the wheel 1 includes a bearing bracket 11, a wheel hub 12 and two bearings 13. Each bearing 13 includes an outer ring 131 and an inner ring 132, the outer ring 131 is fixedly connected to the wheel hub 12, and the inner ring 132 and the frame 21 are respectively fixedly connected to the bearing bracket 11. The bearing bracket 11 includes an inner surface 1111 facing the rotation center of the wheel 1, and the wheel 1 also includes a hollow area 14 surrounded by the inner surface 1111.

[0029] In some embodiments, the cross section of the hollow area 14 in the direction perpendicular to the axial direction of the wheel 1 includes a circle, a polygon or other irregular shapes, which is not limited in the present disclosure. When the cross section of the hollow area 14 in the direction perpendicular to the axial direction of the wheel 1 is a circle, the overall aesthetics and technological sense of the wheel 1 can be improved. Figure 1 As shown, the characteristic dimension D1 of the hollow area may be greater than or equal to one third of the outline diameter D2 of the wheel 1, and less than or equal to two thirds of the outline diameter D2 of the wheel 1, so as to obtain a better hollow wheel appearance without affecting the structural setting of the wheel 1. Alternatively, the outline diameter D2 of the wheel 1 may also be other multiples of the characteristic dimension D1 of the hollow area, and the present disclosure is not limited thereto.

[0030] Among them, the characteristic dimension D1 of the hollow area may refer to the characteristic dimension that can reflect the overall shape of the hollow area. For example, when the hollow area is circular, the characteristic dimension D1 of the hollow area may be the diameter of the circle; when the hollow area is rectangular, the characteristic dimension D1 of the hollow area may be the diagonal length of the rectangle.

[0031] Providing two bearings 13 for the wheel 1 improves the overall structural strength and rotational stability of the wheel 1. The bearing bracket 11 is fixedly connected to the frame 21, and the outer rings 131 of the two bearings 13 are respectively fixedly connected to the wheel hub 12, so that the wheel hub 12 can rotate relative to the frame 21. The inner rings 132 of the two bearings 13 are respectively fixedly connected to the bearing bracket 11, so that the bearings 13 and other peripheral structures of the bearings 13 can be supported by the bearing bracket 11, thereby ensuring the overall structural strength of the wheel 1. The wheel 1 also includes a hollow area 14 surrounded by the inner surface 1111 of the bearing bracket 11, so that the wheel 1 has a hollow appearance, simplifies the structure of the wheel 1, and improves the appearance and technological sense of the wheel 1.

[0032] It should be noted that the inner ring 132 of the bearing 13 can be sleeved on the bearing bracket 11, and can be fixedly connected by interference fit, clamping, threaded connection, welding, etc. The wheel hub 12 can be sleeved on the outer ring 131 of the bearing 13, and can be fixedly connected by interference fit, clamping, threaded connection, welding, etc.

[0033] In some embodiments, the bearing bracket 11 may be a structural member formed by a bracket body 113 , or the bearing bracket 11 may be a structural component formed by assembling and matching two or more bracket bodies 113 , which is not limited in the present disclosure.

[0034] When the bearing support 11 is a support body 113, as Figure 2 , Figure 3 As shown, the bearing bracket 11 may include a supporting body 111 and a connecting structure 112 connected to the supporting body 111, the bearing 13 is matched with the supporting body 111, and the frame 21 is matched with the connecting structure 112. The supporting function of the wheel 1 structure is realized by the cooperation between the supporting body 111 and the bearing 13, and the fixed connection with the frame 21 is realized by the connecting structure 112, so that the structural and functional interference between the supporting body 111 and the connecting structure 112 during the assembly and use process is avoided, and the reliability of the wheel 1 is improved.

[0035] The connection structure 112 may have one, two or more, and the present disclosure is not limited thereto. Figure 2 , Figure 3 As shown, the bearing bracket 11 may include two connection structures 112, which are arranged on opposite sides of the support body 111. The wheel 1 and the frame 21 are assembled by fixedly connecting the connection structures 112 on both sides of the support body 111 with the frame 21, thereby improving the stability of the wheel 1 in use.

[0036] When the bearing support 11 is a structural component formed by assembling and matching two or more support bodies 113, such as Figure 4 As shown, two or more bracket bodies 113 are assembled and matched to form a bearing bracket 11, and partial structures of two or more bracket bodies 113 are assembled to form a support body 111, and at least one bracket body 113 includes a connecting structure 112. When the bearing 13 is matched with multiple bracket bodies 113, it is convenient to adjust and calibrate the position of the bearing 13 when assembling multiple bracket bodies 113, thereby improving the installation accuracy of the bearing 13. For example, the bearing bracket 11 includes two bracket bodies 113 and two bearings 13, and the two bracket bodies 113 are assembled and matched. The main structures 1112 adjacent to the inner sides of the two bracket bodies 113 are spliced ​​into the support body 111, and each bracket body 113 is assembled with a bearing 13, and a connecting structure 112 is provided on the outer side of the main structure 1112 of each bracket body 113. When assembling multiple bracket bodies 113, the positions of the two bearings 13 can be adjusted and calibrated, thereby improving the installation accuracy of the bearing 13.

[0037] It should be noted that the axial width of the support body 111 in the wheel 1 can match the axial width of the hub 12 in the wheel 1, the inner surface 1111 of the bearing bracket 11 can refer to the inner surface 1111 of the support body 111, and the hollow area 14 of the wheel 1 can be surrounded by the inner surface 1111 of the support body 111, so that the axial width of the hollow area 14 in the wheel 1 matches the axial width of the hub 12 in the wheel 1, thereby improving the overall aesthetics of the wheel 1.

[0038] In some embodiments, in the axial direction of the wheel 1 , at least a portion of the connection structure 112 protrudes from the wheel hub 12 to facilitate assembly and cooperation between the frame 21 and the connection structure 112 and avoid structural interference between the frame 21 and the wheel 1 .

[0039] It should be noted that the support body 111 and the connection structure 112 can be integrally formed, and the connection structure 112 can also be assembled to the support body 111 by means of threaded connection, clamping, welding, etc., and the present disclosure does not limit this.

[0040] In some embodiments, Figure 1-Figure 4 As shown, the dot-dash line in the figure represents the rotation center axis of the wheel 1. The wheel 1 may include at least two bearings 13, the bearing bracket 11 includes a left edge and a right edge arranged along the axial direction of the wheel 1, the inner ring 132 of at least one bearing 13 is matched with the left edge, and the inner ring 132 of at least one bearing 13 is matched with the right edge, so as to improve the rotation stability of the wheel 1 by increasing the number of bearings 13 and optimizing the distribution position of the bearings 13.

[0041] In some other embodiments, the wheel 1 may also include a bearing 13 , and the bearing 13 matches the bearing bracket 11 in the axial width of the wheel 1 , thereby simplifying the structure and cost of the wheel 1 .

[0042] It should be noted that the wheel 1 may include one or more bearings 13, and the bearing bracket 11 may include one or more bracket bodies 113, and the present disclosure does not limit this. In some embodiments, when the bearing bracket 11 includes a bracket body 113, the wheel 1 may include one or more bearings 13. In other embodiments, when the bearing bracket 11 includes multiple bracket bodies 113, the wheel 1 may include one or more bearings 13. In still other embodiments, the number of bearings 13 of the wheel 1 may match the number of bracket bodies 113 of the bearing bracket 11, and the bearings 13 may be matched with the bracket bodies 113 in a one-to-one correspondence, so as to facilitate the adjustment and calibration of the position of the bearings 13 when assembling multiple bracket bodies 113, thereby improving the installation accuracy of the bearings 13.

[0043] In some embodiments, the wheel 1 further includes at least one bearing end cover 15, which is fixedly connected to the wheel hub 12 and seals with the side of the bearing 13. The bearing end cover 15 can cooperate with the wheel hub 12 to limit and seal the bearing 13, thereby improving the dust and water resistance of the bearing 13. Figure 3 , Figure 4 As shown, the wheel 1 includes two bearings 13 and a bearing end cover 15. The side of one of the two bearings 13 can be limited and sealed by the wheel hub 12 structure, and the side of the other bearing 13 can be limited and sealed by the bearing end cover 15, so as to simplify the assembly of the wheel 1 and improve the dustproof and waterproof effect of the bearing 13.

[0044] In the above embodiment, the wheel 1 may further include a seal 16, which is disposed between the bearing end cover 15 and the bearing 13, and the seal 16 is sealed with the bearing end cover 15 and the side of the bearing 13.

[0045] In some embodiments, the wheel 1 further includes a tire 17 , which is assembled on the outer side of the hub 12 , so that the wheel 1 can achieve a shock absorbing effect.

[0046] It should be noted that the bearing bracket 11 and the frame 21, between two adjacent bracket bodies 113, and between the bearing end cover 15 and the wheel hub 12 can be fixedly connected by threaded connection, clamping, welding, etc., and the present disclosure does not limit this.

[0047] The present disclosure further proposes a scooter, which includes a scooter body, a frame 21 and the above-mentioned wheel 1, and a bearing bracket 11 is fixedly connected to the frame 21.

[0048] During the use of the scooter, the wheel 1 includes a bearing bracket 11, a bearing 13 and a wheel hub 12. The outer ring 131 of the bearing 13 is fixedly connected to the wheel hub 12, so that the wheel hub 12 can rotate relative to the frame 21 based on the fixed connection between the bearing bracket 11 and the frame 21. The inner ring 132 of the bearing 13 is fixedly connected to the bearing bracket 11, so that the bearing 13 and other peripheral structures of the bearing 13 can be supported by the bearing bracket 11. Since the wheel 1 also includes a hollow area 14 surrounded by the inner surface 1111 of the bearing bracket 11, the wheel 1 has a hollow appearance, which simplifies the structure of the wheel 1 and improves the appearance and technological sense of the wheel 1 and the scooter using the wheel 1.
