[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain the present invention and should not be construed as limiting the invention.

[0022] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this invention. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0023] The mainstream structure of wheels in related technologies is generally made of all-metal materials. Although such wheel structures are low in cost and high in strength, they are also relatively heavy. Moreover, the stamping and forming of all-metal materials (usually steel) is not very effective in achieving complex appearances (such as sharp edges and three-dimensional effects).

[0024] In addition, some wheels in related technologies are made of carbon fiber, such as the entire wheel (rim and spokes) being made of carbon fiber, or only the spokes being made of carbon fiber. This will affect the overall strength of the wheel to some extent and significantly increase the overall cost of the wheel.

[0025] Based on this, see Appendix Figures 1 to 8 A wheel includes a metal rim 10 and a metal inner spoke 30. The wheel also includes a first connecting structure 40 and an outer spoke 20. The outer spoke is made of a non-metallic material and is located outside the inner spoke 30. A portion of the first connecting structure 40 is embedded in the edge of the outer spoke 20 and is fixedly connected to the outer spoke 20. Another portion of the first connecting structure 40 is fixedly connected to the rim 10.

[0026] The wheel in this embodiment has a double-thin-walled spoke structure, which improves the lateral stiffness of the wheel on the one hand, and reduces the amount of material and weight of the spokes on the other hand. In order to reduce the overall weight of the wheel, the material density of the outer spoke 20 can generally be set to be less than the material density of the inner spoke 30 during the design.

[0027] For example, the outer spokes can be made of carbon fiber or engineering plastics, while the inner spokes can be made of metal materials such as steel or aluminum. However, in actual installations, the inner spokes can also be made of magnesium alloy, in which case the density of the non-metallic outer spokes is roughly the same as that of the inner spokes.

[0028] In this embodiment, the outer spoke 20 of the double-spoke wheel is made of a non-metallic material (generally carbon fiber or engineering plastics; carbon fiber will be used as an example below), while the inner spoke 30 and rim 10 are still made of metallic materials, typically steel. The non-metallic structure of the outer spoke 20 can further reduce the overall weight of the wheel based on the weight reduction of the double-spoke design.

[0029] In other words, the wheel in this embodiment achieves a hybrid material structure of steel and carbon fiber, which retains the high load-bearing capacity and low cost advantages of the steel inner spokes 30 and rim 10, while also enabling the wheel to be lightweight and have diverse appearance.

[0030] In addition, the wheel in this embodiment is designed with a first connecting structure 40 and a second connecting structure 50. The first connecting structure 40 and the second connecting structure 50 are generally made of metal and are used to connect the carbon fiber outer spoke 20 structure with the steel rim 10 and the inner spoke 30, respectively.

[0031] The first connecting structure 40 connects the radial edge of the outer spoke 20 to the hub, and the second connecting mechanism connects the radial center of the outer spoke 20 to the inner spoke 30. In other words, both the radial edge and center of the outer spoke 20 have supporting structures, which can better ensure the overall strength of the outer spoke 20.

[0032] In this embodiment, the first connecting structure 40 fits into the outer spoke 20. During production, the carbon fiber composite outer spoke 20 is generally formed by layup curing. During the layup forming of the outer spoke 20, the outer spoke 20 forms a layup on the first connecting structure 40. See Appendix. Figure 2 This forms a structure in which the first connecting structure 40 is embedded in the outer spoke 20; another side of the first connecting structure 40 is connected to the rim 10, that is, the first connecting structure 40 serves as an intermediate connecting medium between the outer and inner spokes 30 and the inner spoke 30.

[0033] In this embodiment, the first connecting structure 40 is generally pre-formed as an integral part with the outer spoke 20, and then connected to the rim 10 together with the outer spoke 20.

[0034] In this embodiment, the specific structure of the first connecting structure 40 is not limited. For example, the first connecting structure 40 can be set as a ring or a multi-segmented arc.

[0035] In this embodiment, the second connecting structure 50 fits into the outer spoke 20. Similarly, during production, the outer spoke 20 forms a layup on the second connecting structure 50. (See attached diagram.) Figure 3This forms a structure in which the second connecting structure 50 is embedded in the outer spoke 20. On the other hand, the second connecting mechanism is connected to the inner spoke 30, that is, the second connecting mechanism serves as an intermediate connecting medium between the inner spoke 30 and the outer spoke 20.

[0036] In this embodiment, the industry problem of welding carbon fiber to steel rim 10 is cleverly solved by the arrangement of the first connecting structure 40 and the second connecting structure 50, eliminating the need for expensive and questionable large-area structural adhesive bonding. Furthermore, it ensures better wheel structural strength.

[0037] This embodiment, by setting the outer spokes 20 as a non-metallic material while retaining the metallic material of the rim 10 and inner spokes 30, can reduce the overall weight of the wheel while ensuring its load-bearing capacity, thus achieving wheel lightweighting. Moreover, the non-metallic material of the outer spokes 20 allows for more possibilities in the wheel's shape and structure, making it easier to achieve diversity in the wheel's appearance, thus balancing the wheel's strength, appearance, lightweighting, and cost.

[0038] As one embodiment of the present invention, see Appendix Figure 2 and attached Figure 4 The first connecting structure 40 includes an annular connecting portion 41 and an embedded fitting portion 42. The embedded fitting portion 42 is disposed at the first end of the annular connecting portion 41 and extends toward the inner side of the annular connecting portion 41. The embedded fitting portion 42 is embedded in the outer wheel spoke 20 and is fixedly connected to the outer wheel spoke 20. The second end of the annular connecting portion 41 extends out of the outer wheel spoke 20 and is circumferentially fixedly connected to the rim 10.

[0039] In this embodiment, the annular structure of the annular connecting part 41 can form a support between the outer wheel spoke 20 and the rim 10 in the circumferential direction, resulting in higher overall support strength. Moreover, the integrated annular structure can improve the structural strength of the first connecting structure 40 itself, thereby improving the strength of the wheel.

[0040] In this embodiment, the insert fitting portion 42 extends toward the inner side of the annular connecting portion 41, and the cross-sectional shape of the annular connecting portion 41 and the insert fitting portion 42 is an inverted "L" shape (see Appendix). Figure 2 This provides a larger fitting space for the outer spokes 20 and the embedded fitting part 42, making it easier for the outer spokes 20 to be combined with the embedded fitting part 42 during the layup process.

[0041] In this embodiment, the connection points of the first connecting structure 40 with the outer spokes 20 and the rim 10 are respectively located at opposite ends of the annular connecting portion 41, thereby achieving spacing and partitioning of the connection positions between the outer spokes 20 and the rim 10. In actual production, the first connecting structure 40 and the rim 10 are usually connected by welding. Through the structural arrangement of the annular connecting portion 41 and the embedded fitting portion 42, the welding point between the annular connecting portion 41 and the rim 10 can be kept away from the joint area between the embedded fitting portion 42 and the outer spokes 20, thereby effectively avoiding the damage to the performance of the carbon fiber composite material caused by the high temperature of welding.

[0042] As one embodiment of the present invention, see Appendix Figure 4 The surface of the embedded mating part 42 has several protrusions 421, which are mechanically locked to the outer wheel spokes 20. In this embodiment, when the outer wheel spokes 20 are laid up and cured on the embedded mating part 42, the carbon fiber material can be directly wrapped around the protrusions 421, thereby forming a mechanical interlocking structure between the protrusions 421 and the carbon fiber. Compared with simple friction or chemical bonding, this mechanical interlocking structure has better fatigue resistance and impact resistance, which can significantly improve the bonding strength between the outer wheel spokes 20 and the first connecting structure 40, thereby improving the overall structural reliability of the wheel.

[0043] In another embodiment of the present invention, a plurality of grooves 422 are formed on the surface of the embedded mating part 42, and the grooves 422 are mechanically locked with the outer spoke 20. This embodiment does not limit the specific shape of the grooves 422; for example, they can be arc-shaped grooves, straight grooves, or irregular grooves. Similarly, the carbon fiber material of the outer spoke 20 can be directly filled and cured into the grooves 422 during layup molding, forming a mechanical interlock with the embedded mating part 42, which has the same advantages as the aforementioned protrusion 421 scheme. It is understood that in actual installation, protrusions 421 can be provided on two opposite surfaces of the embedded mating part 42, or only on one surface, and protrusions 421 and grooves 422 can also be provided simultaneously to further enhance the locking effect.

[0044] The aforementioned protrusions 421 and grooves 422 increase the effective contact area between the embedded mating part 42 and the outer spoke 20, and also achieve stable mechanical interlocking. This effectively prevents interface peeling or slippage caused by stress concentration when transmitting circumferential torque and axial loads. Compared to chemical bonding with adhesives or frictional forces from interference fits, the mechanical interlocking structure of this invention offers higher durability and environmental adaptability.

[0045] It should be noted that, to enhance the bonding strength between the carbon fiber outer spoke 20 and the first connecting structure 40, the proposed solutions are not limited to the aforementioned protrusion 421 or groove 422. For example, grooves, hooks, or wavy textures can be provided on the surface of the embedded mating part 42, or the embedded mating part 42 itself can be designed as a hollow frame structure (such as a mesh or honeycomb structure), so that the carbon fiber, after curing, penetrates the hollow area to form a "rivet-like" interlock. Any structure that can achieve mechanical interlocking between the outer spoke 20 and the first connecting structure 40 should be considered to fall within the protection scope of this application.

[0046] In one embodiment of the present invention, the first connecting structure 40 is integrally formed with the rim 10. In this embodiment, the first connecting structure 40 and the rim 10 form an integral structure. During production, the edge of one end of the rim 10 can be folded inward to form the embedded fitting part 42 described above. Then, carbon fiber composite material is directly laid on that end of the rim 10 and cured, eliminating the need for a separate first connecting component and its welding process, thereby avoiding the risk of damage to the outer spoke 20 caused by welding heat.

[0047] Understandably, in actual implementation, the first connecting structure 40 can be welded to the rim 10 first, and then the outer spokes 20 can be laid up and formed, which can also avoid the influence of welding heat on the outer spokes 20.

[0048] As one embodiment of the present invention, see Appendix Figure 5 The wheel further includes at least one second connecting structure 50. Along the radial direction of the wheel, the second connecting structure 50 is disposed inside the first connecting structure 40. The inner spoke 30 has a central hole 33 and a plurality of first connecting holes 32 circumferentially distributed around the central hole 33. The outer spoke 20 has second connecting holes 22 corresponding one-to-one with the first connecting holes 32. The second connecting structure 50 connects the inner spoke 30 and the outer spoke 20. The second connecting structure 50 has a through hole that passes through the first connecting hole 32 and the second connecting hole 22 corresponding to the first connecting hole 32.

[0049] The second connecting structure 50 includes a first sleeve 52 and a second sleeve 51. The central cavities of the first sleeve 52 and the second sleeve 51 are interconnected and form the through hole. The first sleeve 52 is integrally formed with the outer spoke 20. One end of the second sleeve 51 is fixedly connected to the inner spoke 30, and the other end is fitted and connected to the first sleeve 52.

[0050] In this embodiment, the through hole of the second connecting structure 50 serves as the installation space for the connector that connects the wheel and the hub.

[0051] The structure of multiple second connecting structures 50 enables multi-point connection between the outer spokes 20 and the inner spokes 30, improving the connection support strength. The design of the first connecting hole 32 limits the installation position of the second sleeve 51, improving assembly efficiency.

[0052] As one embodiment of the present invention, see Appendix Figure 1 , 3 6. The second connecting structure 50 includes a first sleeve 52 and a second sleeve 51. The central cavities of the first sleeve 52 and the second sleeve 51 are interconnected and form the through hole. The first sleeve 52 is integrally formed with the outer spoke 20. One end of the second sleeve 51 is fixedly connected to the inner spoke 30, and the other end is fitted and connected to the first sleeve 52.

[0053] As one embodiment of the present invention, see Appendix Figure 3 and Figure 5 The second sleeve 51 includes a first cylindrical body 511 and a second cylindrical body 512. The diameter of the first cylindrical body 511 is smaller than the diameter of the second cylindrical body 512. The first cylindrical body 511 and the second cylindrical body 512 are connected and form a positioning platform at the connection. The positioning platform abuts against the outer surface of the inner spoke 30. The first cylindrical body 511 is inserted into the first connecting hole 32 and fixedly connected to the inner spoke 30. A fitting groove 513 is formed on the side wall of the second cylindrical body 512. The second cylindrical body 512 is embedded in the outer spoke 20. A portion of the outer spoke 20 is formed in the fitting groove 513 and mechanically locked with the fitting groove 513.

[0054] In this embodiment, by setting a first cylindrical body 511 and a second cylindrical body 512 with different diameters and forming a positioning platform at the connection, the second connecting structure 50 can be precisely positioned on the inner spoke 30. Specifically, when the first cylindrical body 511 is inserted into the first connecting hole 32 of the inner spoke 30, the positioning platform abuts against the outer surface of the inner spoke 30, which not only restricts the axial displacement of the second connecting structure, but also provides a stable assembly reference for subsequent fixed connections (such as riveting, welding, or thread locking). At the same time, the second cylindrical body 512 has a larger diameter, which facilitates its connection with the outer spoke 20. Moreover, the fitting groove 513 opened on its side wall is filled with carbon fiber material when the outer spoke 20 is laid up and cured. After curing, it forms a two-way mechanical lock in the radial and axial directions, which significantly improves the tensile and torsional resistance between the second sleeve 51 and the outer spoke 20.

[0055] In this embodiment, the second sleeve 51 and the inner spoke 30 are fixedly connected by at least one of riveting, welding and threaded connection, that is, the second cylinder 512 and the inner spoke 30 in this embodiment adopt the above-mentioned connection form.

[0056] As mentioned above, in this embodiment, the second sleeve 51 and the connection parts of the outer spoke 20 and the inner spoke 30 are arranged in a partitioned and spaced manner, which can also avoid the damage of the outer spoke 20 by the welding heat.

[0057] In this embodiment, the fitting groove 513 formed on the side wall of the second cylinder 512 has a similar function to the groove 422 in the first connecting structure 40 mentioned above. When the outer spoke 20 is laid up and cured, a portion of the carbon fiber can be laid up in the fitting groove 513 to achieve mechanical interlocking with the second sleeve 51.

[0058] As one embodiment of the present invention, see Appendix Figure 5 A plurality of fitting grooves 513 are formed on the side wall of the second cylinder 512, and the plurality of fitting grooves 513 are circumferentially distributed around the axis of the second cylinder 512. The fitting groove 513 extends circumferentially along the second cylinder 512, or the fitting groove 513 extends axially along the second cylinder 512.

[0059] In this embodiment, multiple fitting grooves 513 are formed on the side wall of the second cylinder 512. The design of multiple fitting grooves 513 can increase the bonding area between the outer spoke 20 and the second connecting structure 50 when the outer spoke 20 is laid up and cured, thereby improving the connection strength.

[0060] In this embodiment, the specific configuration of the fitting groove 513 is not specifically limited. For example, the fitting groove 513 mentioned in this embodiment can be configured to extend in the circumferential direction or in the axial direction. Of course, it is conceivable that multiple fitting grooves 513 can also be configured to have both circumferential and axial extensions.

[0061] From the appendix Figure 3 As can be seen from the diagram, when the outer spokes 20 and the second sleeve 51 are connected in this embodiment, the outer spokes 20 form a wrapping structure on both the inner and outer side walls of the second sleeve 512. This, combined with the mechanical interlocking structure in the fitting groove 513 on the second sleeve 512, can improve the bonding strength between the outer spokes 20 and the second connecting structure 50.

[0062] As one embodiment of the present invention, see Appendix Figure 3 The second sleeve 51 is fixedly connected to the inner spoke 30 by at least one of riveting, welding and threaded connection.

[0063] In one embodiment of the present invention, the outer spoke 20 is formed by carbon fiber composite material layup curing or forging carbon fiber, and the first connecting structure 40 and the outer spoke 20 form a mechanical interlocking structure; the second connecting structure 50 and the outer spoke 20 form a mechanical interlocking structure.

[0064] In this embodiment, the first connecting structure 40 and the second connecting structure 50 are respectively configured to form a mechanical interlocking structure with the outer spoke 20. However, the specific form of the mechanical interlocking structure is not limited. In addition to the protrusion 421, groove 422 and fitting groove 513 mentioned above, other structures that can form a mechanical interlocking structure should also be considered to fall within the protection scope of this application.

[0065] In one embodiment of the present invention, a plurality of circumferentially spaced external air holes 21 are formed on the outer spoke 20, and a plurality of circumferentially spaced internal air holes 31 are formed on the inner spoke 30, wherein the internal air holes 31 are located at the intervals between adjacent external air holes 21.

[0066] In this embodiment, the outer air vent 21 and the inner air vent 31 are staggered, meaning they do not overlap in the circumferential direction. This design has at least the following beneficial effects: First, it facilitates the formation of a tortuous airflow path for heat dissipation during wheel rotation, effectively carrying away the heat generated by the braking system and preventing external debris such as sand and mud from directly penetrating the wheel interior through the air vents, thus reducing external erosion of the inner spokes 30 and brake disc; second, from an aesthetic perspective, the incomplete transparency of the outer air vent 21 and the inner air vent 31 enhances the visual hierarchy of the wheel, balancing functionality and design aesthetics.

[0067] It is understood that the number, shape, and specific distribution angle of the external air vents 21 and the internal air vents 31 are not limited to the forms described in this embodiment. For example, the external air vents 21 can be fan-shaped, circular, or irregularly shaped, and the internal air vents 31 can also be adjusted accordingly; provided that the structural strength requirements are met, some of the internal air vents 31 and the external air vents 21 can be partially overlapped to achieve differentiated ventilation effects. All technical solutions based on the staggered arrangement of the internal and external air vents 21 to balance heat dissipation, protection, and structural strength fall within the protection scope of this invention.

[0068] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
