[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] To address the problems of high processing difficulty, high cutting force, poor surface quality, high risk of deformation, and high cost in the machining of grooves on the flanges of wheel spokes in the prior art, this utility model provides a wheel.

[0035] like Figures 1 to 12 As shown, the wheel includes spokes 10 and an assembly ring 20. The spokes 10 have a central hole 11 and an annular flange 12 surrounding the edge of the central hole 11. The annular flange 12 has a first connecting structure. The assembly ring 20 has a second connecting structure and a third connecting structure arranged sequentially along its axial direction. The second connecting structure cooperates with the first connecting structure to connect the assembly ring 20 and the spokes 10. The third connecting structure cooperates with a fourth connecting structure on the decorative cover to connect the decorative cover and the assembly ring 20.

[0036] By adding an assembly ring 20 and setting a second and third connecting structure on the assembly ring 20, the processes that require a lot of machining are transferred to the assembly ring 20, while the spokes 10 only need to be machined to the first connecting structure. This can reduce machining time by at least 70%, greatly reduce the machining difficulty of the spokes 10, and help improve the machining progress of the wheel. It is also beneficial to improve the machining efficiency of the wheel through batch machining.

[0037] It should be noted that in this application, the mounting ring 20 is detachably connected to the spoke 10; and / or, the mounting ring 20 is detachably connected to the decorative cover. This ensures ease of assembly and disassembly between the mounting ring 20 and the spoke 10, as well as between the mounting ring 20 and the decorative cover.

[0038] It should be noted that in this application, the assembly ring 20 is fastened to the spoke 10; and / or, the assembly ring 20 is fastened to the decorative cover. This ensures the reliability of the connection between the assembly ring 20 and the spoke 10, as well as the reliability of the connection between the assembly ring 20 and the decorative cover.

[0039] It should be noted that in this application, the first connecting structure and the second connecting structure are in a concave-convex fit; and / or, the third connecting structure and the fourth connecting structure are in a snap-fit ​​fit. Thus, by setting the first connecting structure and the second connecting structure in a concave-convex fit configuration, the ease of processing of the first connecting structure and the second connecting structure, as well as the ease of assembly and reliability of connection between the two are ensured.

[0040] Example 1

Thus, while ensuring convenient assembly between the spokes 10 and the mounting ring 20, the connection between the spokes 10 and the mounting ring 20 is achieved through the concave-convex fit of the first mounting step 13 and the second mounting step 21.

[0042] like Figure 2 As shown, the first step surface of the first mounting step 13 is formed on the inner circumferential surface of the axial end of the annular flange 12 away from the central hole 11; the second step surface of the second mounting step 21 is formed on the outer circumferential surface of the mounting ring 20 facing the spoke 10. In this way, it is ensured that the first mounting step 13 and the second mounting step 21 can achieve a concave-convex fit.

[0043] It should be noted that, in this embodiment, as Figure 2 As shown, the first assembly step 13 and the second assembly step 21 are interference-fitted. This ensures ease of assembly between the first assembly step 13 and the second assembly step 21.

[0044] Optionally, the interference fit on one side of the first assembly step 13 can be in the range of 0.05-0.8mm.

[0045] Preferably, the interference fit on one side of the first assembly step 13 is 0.3 mm.

This ensures that the mounting ring 20 can be directly installed onto the spoke 10 by screwing, thus ensuring the ease of installation and removal of the mounting ring 20.

[0058] Example 6

[0059] It should be noted that the difference between this embodiment and Embodiment 4 is that, as shown in the following... Figure 11 and Figure 12 As shown, the first assembly step 13 and the second assembly step 21 are welded together.

[0060] It should be noted that in one embodiment of this application (not shown), the difference from embodiment four is that the first assembly step 13 and the second assembly step 21 are connected by a key.

[0061] like Figures 1 to 12 As shown, the third connecting structure is a snap-fit ​​groove 22 formed circumferentially on the assembly ring 20; the fourth connecting structure is a snap-fit ​​protrusion formed circumferentially on the decorative cover, which engages with the snap-fit ​​groove 22. This ensures convenient installation and removal of the decorative cover.

[0062] Furthermore, such as Figures 1 to 6 As shown, the snap-fit ​​groove 22 is an annular groove formed on the outer circumferential surface of the assembly ring 20, and the snap-fit ​​protrusion is an annular protrusion formed on the inner circumferential surface of the decorative cover; or, the snap-fit ​​groove 22 is a plurality of spaced-apart limiting grooves formed on the outer circumferential surface of the assembly ring 20, and the snap-fit ​​protrusion is a plurality of spaced-apart limiting blocks formed on the inner circumferential surface of the decorative cover, with the plurality of limiting blocks corresponding one-to-one with the plurality of limiting grooves. In this way, the connection between the assembly ring 20 and the decorative cover is achieved through the cooperation of the continuous annular grooves and the continuous annular protrusions, or the connection between the assembly ring 20 and the decorative cover is achieved through the cooperation of the plurality of spaced-apart limiting grooves and the plurality of spaced-apart limiting blocks.

[0063] Furthermore, such as Figures 7 to 12 As shown, the snap-fit ​​groove 22 is an annular groove formed on the inner circumferential surface of the assembly ring 20, and the snap-fit ​​protrusion is an annular protrusion formed on the outer circumferential surface of the decorative cover; or, the snap-fit ​​groove 22 is a plurality of spaced-apart limiting grooves formed on the inner circumferential surface of the assembly ring 20, and the snap-fit ​​protrusion is a plurality of spaced-apart limiting blocks formed on the outer circumferential surface of the decorative cover, with the plurality of limiting blocks corresponding one-to-one with the plurality of limiting grooves. The connection between the assembly ring 20 and the decorative cover is achieved through the cooperation of the continuous annular grooves and the continuous annular protrusions, or through the cooperation of the plurality of spaced-apart limiting grooves and the plurality of spaced-apart limiting blocks.

[0064] The present invention provides a wheel comprising spokes 10 and an assembly ring 20. The spokes 10 have a central hole 11 and an annular flange 12 surrounding the edge of the central hole 11. The annular flange 12 has a first connecting structure. The assembly ring 20 has a second connecting structure and a third connecting structure arranged sequentially along its axial direction. The second connecting structure cooperates with the first connecting structure to connect the assembly ring 20 and the spokes 10, and the third connecting structure cooperates with a fourth connecting structure on a decorative cover to connect the decorative cover and the assembly ring 20.

[0065] By adding an assembly ring 20 and setting a second and third connecting structure on the assembly ring 20, the processes that require a lot of machining are transferred to the assembly ring 20, while the spokes 10 only need to be machined to the first connecting structure. This can reduce machining time by at least 70%, greatly reduce the machining difficulty of the spokes 10, and help improve the machining progress of the wheel. It is also beneficial to improve the machining efficiency of the wheel through batch machining.
