In the related art, the wheel structure usually includes a tire, a hub, a spoke, and a central shaft, and various forms of spokes are connected to the hub, so as to obtain an expected appearance effect. However, due to the limitation of the spoke and other basic structures, the wheel in the related art has the problems of a complex structure and a lack of sense of science and technology.
According to embodiments of a first aspect of the present disclosure, a wheel for a scooter is provided, and is assembled and fitted with a frame of the scooter. The wheel includes a bearing support, a hub, at least one bearing and a hollow area. The bearing support includes an inner surface facing towards a rotation center of the wheel. Each bearing includes an outer ring and an inner ring, the outer ring is fixedly connected to the hub, and the inner ring and the frame are fixedly connected to the bearing support, respectively. The hollow area is surrounded by the inner surface.
According to embodiments of a second aspect of the present disclosure, a scooter is provided. The scooter includes a main body, a frame connected to the main body and a wheel coupled to the frame. The wheel includes a bearing support, a hub, at least one bearing and a hollow area. The bearing support includes an inner surface facing towards a rotation center of the wheel. Each bearing includes an outer ring and an inner ring, the outer ring is fixedly connected to the hub, and the inner ring and the frame are fixedly connected to the bearing support, respectively. The hollow area is surrounded by the inner surface. The bearing support is fixedly connected to the frame.
It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and do not limit the present disclosure.
The accompanying drawings incorporated into the specification and forming part of the specification, illustrate embodiments in accordance with the present disclosure, and are used with the specification to explain the principles of the present disclosure.
Exemplary embodiments will be described in detail, and examples of the embodiments will be shown in the accompanying drawings. When the following description relates to the accompanying drawings, the same numbers in different accompanying drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
The present disclosure provides a wheel assembled and fitted with a frame, and the wheel includes a bearing support, a hub and at least one bearing. The bearing includes an outer ring and an inner ring, the outer ring is fixedly connected to the hub, and the inner ring and the frame are fixedly connected to the bearing support, respectively. The bearing support includes an inner surface facing towards a rotation center of the wheel. The inner surface defines a hollow area surrounded by the inner surface.
Since the wheel includes the bearing support, the bearing and the hub, and the outer ring of the bearing is fixedly connected to the hub, the hub can rotate relative to the frame based on a fixed connection between the bearing support and the frame. The inner ring of the bearing is fixedly connected to the bearing support, to realize a support function for the bearing and other structures around the bearing through the bearing support. Since the wheel further includes the hollow area surrounded by the inner surface of the bearing support, the wheel obtains a hollow appearance effect, thus simplifying the wheel structure, and improving the appearance effect and the sense of science and technology of the wheel. Since the wheel structure is simplified, the material used for the wheel and the cost of the wheel are reduced, and the carbon emission is reduced.
In the above embodiment, one, two or more bearings may be provided, which is not limited by the present disclosure. The wheel structure is exemplarily described below by taking an example in which the wheel includes two bearings.
In some embodiments, a section of the hollow area 14 perpendicular to an axial direction of the wheel 1 has a circle shape, a polygon shape or other irregular shapes, which is not limited by the present disclosure. When the section of the hollow area 14 perpendicular to the axial direction of the wheel 1 has the circle shape, the overall aesthetics and the sense of science and technology of the wheel 1 can be improved. As shown in
The characteristic dimension D1 of the hollow area can refer to a characteristic dimension that can reflect an overall shape of the hollow area. For example, when the hollow area has the circle shape, the characteristic dimension D1 of the hollow area can be a diameter of the circle. When the hollow area has the rectangle shape, the characteristic dimension D1 of the hollow area can be a diagonal length of the rectangle.
Since two bearings 13 are provided for the wheel 1, the overall structural strength and the rotation stability of the wheel 1 are improved. Since the bearing support 11 is fixedly connected to the frame 21, and the outer rings 131 of the two bearings 13 are fixedly connected to the hub 12, respectively, the hub 12 can rotate relative to the frame 21. The inner rings 132 of the two bearings 13 are fixedly connected to the bearing support 11, respectively, so as to support the bearing 13 and other structures around the bearing 13 through the bearing support 11, thus ensuring the overall structural strength of the wheel 1. Since the wheel 1 further includes the hollow area 14 surrounded by the inner surface 1111 of the bearing support 11, the wheel 1 obtains a hollow appearance effect, thus simplifying the structure of the wheel 1, and improving the appearance effect and the sense of science and technology of the wheel 1.
It should be noted that the inner ring 132 of the bearing 13 can be fitted over the bearing support 11, and a fixed connection can be realized by interference fit, clamping, threaded connection, welding, etc. The hub 12 can be fitted over the outer ring 131 of the bearing 13, and a fixed connection can be realized by interference fit, clamping, threaded connection, welding, etc.
In some embodiments, the bearing support 11 may be a structural member formed by one support body 113, or the bearing support 11 may also be a structural assembly formed by two or more support bodies 113 assembled and fitted with each other, which is not limited by the present disclosure.
When the bearing support 11 includes one support body 113, as shown in
One, two or more connecting structures 112 may be provided, which is not limited by the present disclosure. In some embodiments, as shown in
When the bearing support 11 is the structural assembly formed by two or more support bodies 113 assembled and fitted with each other, as shown in
It should be noted that a width of the supporting body 111 in a axial direction of the wheel 1 can match with a width of the hub 12 in the axial direction of the wheel 1, the inner surface 1111 of the bearing support 11 can refer to an inner surface of the supporting body 111, and the hollow area 14 of the wheel 1 can be surrounded by the inner surface of the supporting body 111, so that a width of the hollow area 14 in the axial direction of the wheel 1 matches with the width of the hub 12 in the axial direction of the wheel 1, thus improving the overall aesthetics of the wheel 1.
In some embodiments, at least a part of the connecting structure 112 protrudes beyond the hub 12 in the axial direction of the wheel 1, so as to facilitate the assembling and fitting of the frame 21 and the connecting structure 112 and also to avoid the structural interference between the frame 21 and the wheel 1.
It should be noted that the supporting body 111 and the connecting structure 112 can be integrally formed, and the connecting structure 112 can also be assembled to the supporting body 111 by means of threaded connection, clamping, welding, etc. The present disclosure is not limited to this.

In other embodiments, when the bearing support 11 includes a plurality of support bodies 113, the wheel 1 may include one or more bearings 13. In still other embodiments, a number of the bearings 13 of the wheel 1 can match with a number of the support bodies 113 of the bearing support 11, and the bearings 13 can be correspondingly fitted with the support bodies 113 one to one, so as to adjust and calibrate the positions of the bearings 13 when assembling a plurality of support bodies 113, thus improving the mounting accuracy of the bearings 13.
In some embodiments, the wheel 1 further includes at least one bearing end cover 15. The bearing end cover 15 is fixedly connected to the hub 12, and hermetically fitted with a side surface of the bearing 13. The bearing end cover 15 can be fitted with the hub 12 to limit and seal the bearing 13, thus improving the dust-proof effect and the water-proof effect of the bearing 13. For example, as shown in
In the above embodiment, the wheel 1 may further include a sealing member 16 arranged between the bearing end cover 15 and the bearing 13, and the sealing member 16 is hermetically fitted with the bearing end cover 15 and the side surface of the bearing 13. Since the sealing member 16 seals between the bearing end cover 15 and the bearing 13, the sealing effect on the side surface of the bearing 13 is improved.
In some embodiments, the wheel 1 further includes a tire 17 assembled to an external side of the hub 12, so that the wheel 1 obtains a damping effect.
It should be noted that the fixed connection between the bearing support 11 and the frame 21, between two adjacent support bodies 113, and between the bearing end cover 15 and the hub 12 can be realized by threaded connection, clamping, welding, etc., which is not limited by the present disclosure.
