Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a wheel. Background Technology

[0002] A wheel generally consists of a rim and spokes. The outer surface of the spoke edge is connected to the inner surface of the rim where the spokes are mounted, and the spokes and rim are welded together to form a whole.

[0003] In order to reduce the weight of existing wheels, the hub and spoke parts are often replaced with metals with lower density than steel, such as aluminum alloys. However, the hub and spoke structure of aluminum alloys is often unable to withstand the lateral torque of the axle when the wheel turns. If the hub thickness is increased to improve its torsional strength, it will lead to excessive material costs.

[0004] Existing wheels integrate the spokes into a double-layered thin-walled structure, which improves the lateral stiffness of the wheel on the one hand, and reduces the amount of material used and weight on the other. However, the assembly efficiency of the double-layered spoke assembly process is low, which in turn affects the production efficiency of the wheel. Utility Model Content

[0005] This utility model aims to solve one of the technical problems in related technologies to a certain extent. Therefore, this utility model provides a wheel with the advantage of easy assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wheel, comprising an outer spoke, an inner spoke, and a rim, wherein the outer spoke and the inner spoke are sequentially fixedly connected to the inner wall of the rim along the axial direction of the rim, the inner edge of the central hole of the inner spoke is connected to the inner edge of the central hole of the outer spoke, a first cavity is formed on the wheel between the outer spoke and the inner spoke, the outer spoke has a plurality of external air holes communicating with the first cavity, and the inner spoke has a plurality of internal air holes communicating with the first cavity, wherein the plurality of external air holes and the plurality of internal air holes are interconnected through the first cavity.

[0007] Furthermore, the inner edge of the center hole of at least one of the inner spokes and the outer spokes is bent toward the other to form a bend, and the inner spokes and the outer spokes are connected through the bend.

[0008] Furthermore, a first central hole is formed at the center of the outer spoke, and a second central hole is formed at the center of the inner spoke. The wheel includes a central connecting cylinder, with both ends of the central connecting cylinder fixedly connected to the outer spoke and the inner spoke, respectively, and communicating with the first central hole and the second central hole. The rim, outer spoke, inner spoke, and central connecting cylinder together define the first cavity. By providing a central connecting cylinder, the lateral stiffness of the wheel can be improved.

[0009] Furthermore, the outer spoke includes a first mounting plate and a first support portion. The first support portion is arranged around the first mounting plate, and the outer side of the first support portion is connected to the inner wall of the rim. The center of the first mounting plate forms the first center hole. The first mounting plate is connected to the inner spoke through the center connecting cylinder. The outer air hole is formed on the first support portion, and the outer surface of the first support portion is connected to the outer surface of the first mounting plate.

[0010] Furthermore, a plurality of recesses are formed at the inner edge of the first support portion, distributed around the axis of the rim. The first mounting plate includes a center plate and radial extension plates. The center plate has the first center hole. The radial extension plates protrude radially from the outer side wall of the center plate and correspond one-to-one with the recesses. The radial extension plates are disposed within the corresponding recesses, and the outer surfaces of the center plate and the radial extension plates are on the same plane. This improves the overall strength and aesthetics of the wheel.

[0011] Furthermore, the first support portion includes an outer support section and an inner support section. The inner side of the outer support section and the outer side of the inner support section are connected to form a raised transition section. The outer surface of the raised transition section protrudes outward along the axial direction of the rim, intersecting with the outer surfaces of the outer and inner support sections. The external vent penetrates the outer support section, and the inner edge of the inner support section is connected to the first mounting plate. The outer spokes have an overall concave-convex structure, which can improve the overall strength of the outer spokes. Moreover, the external vents are located in the outer support section, which further facilitates heat dissipation and improves heat dissipation efficiency.

[0012] Furthermore, the inner spoke includes a second mounting plate and a second support portion. The second support portion is arranged around the second mounting plate, and its outer side is connected to the inner wall of the rim. The second support portion has the inner air hole formed on it. The inner edge of the first mounting plate and the inner edge of the second mounting plate are connected by the central connecting cylinder. This facilitates the assembly and connection of the inner and outer spokes and improves the stability of the connection.

[0013] Furthermore, the inner spoke includes a second mounting plate and a second support portion. The second support portion is disposed around the second mounting plate, and its outer side is connected to the inner wall of the rim. The second support portion has the inner air hole formed thereon. The inner edge of the first mounting plate and the inner edge of the second mounting plate are connected by the central connecting cylinder. This improves the lateral stiffness of the wheel.

[0014] Furthermore, the wheel includes multiple connecting sleeves. Multiple mounting through holes are formed on the outer spokes, surrounding the rim axis. The mounting through holes are disposed on a first mounting plate of the outer spokes. Connecting through holes corresponding to the mounting through holes are formed on the inner spokes, and the connecting through holes are disposed on a second mounting plate of the inner spokes. Multiple connecting sleeves are fixedly disposed between the outer spokes and the inner spokes. The two ends of the connecting sleeves are fixedly connected to the outer spokes and the inner spokes, respectively, and connect the mounting through holes and the corresponding connecting through holes.

[0015] Furthermore, the connecting sleeve includes a sleeve body and a second positioning boss. The second positioning boss is disposed on the outer wall surface of the sleeve body and located at the end of the connecting sleeve that mates with the inner wheel spoke. The second positioning boss protrudes radially from the outer edge of the connecting through hole. The second positioning boss abuts against the inner wheel spoke on the outer side of the inner wheel spoke, or the second positioning boss abuts against the inner wheel spoke on the inner side of the inner wheel spoke.

[0016] Furthermore, the outer spoke includes a flange that folds from the edge of the outer air hole toward the inner spoke.

[0017] In this technical solution, during wheel assembly, there is no relative positional relationship between the outer air holes on the outer spokes and the inner air holes on the inner spokes, which reduces the assembly precision requirements, simplifies the production process, and improves production efficiency. In addition, the multiple outer air holes and multiple inner air holes form an interconnected structure, which improves the heat dissipation efficiency of the wheel through the outer air holes and inner air holes.

[0018] Furthermore, the wheel hub spokes employ a double-layer structure combining outer and inner spokes, with corresponding connecting through holes and mounting through holes communicating with each other, forming a space for mounting fasteners (e.g., mounting screws) to pass through. When the wheel is fixedly connected to the axle, the mounting fasteners pass through this space and are fixed to the axle. When the vehicle turns, the torque transmitted from the axle first acts on the connection between the connecting through holes and the corresponding mounting through holes, and then applies force to the outer and inner spokes, thereby driving the outer rim to rotate. During this process, the connection between the connecting through holes and the mounting through holes applies a main radial force to the outer and inner spokes, respectively. As a result, the thin-walled outer and inner spokes do not bear excessive torque, which can significantly improve the lateral stiffness of the wheel and enhance NVH (noise, vibration, and harshness) performance.

[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 this utility model and should not be construed as limiting it.

[0041] 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 utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0042] See Figures 1 to 3 One embodiment of this utility model discloses a wheel, including an outer spoke 10, an inner spoke 20, and a rim 30. The outer spoke 10 and the inner spoke 20 are sequentially fixedly connected to the inner wall of the rim 30 along the axial direction of the rim 30. The inner edge of the center hole of the inner spoke 20 is connected to the inner edge of the center hole of the outer spoke 10. A first cavity 40 is formed on the wheel between the outer spoke 10 and the inner spoke 20. The outer spoke 10 has a plurality of external air holes 121 communicating with the first cavity 40. The inner spoke 20 has a plurality of internal air holes 221 communicating with the first cavity 40. The plurality of external air holes 121 and the plurality of internal air holes 221 are interconnected through the first cavity 40.

[0043] In the wheel provided by this utility model, the spoke portion of the wheel adopts a double-layer structure consisting of an outer spoke 10 and an inner spoke 20. The outer spokes 10 and the inner spokes 20 are connected on the outside by a rim 30, and their inner sides are also connected to each other. Furthermore, the outer spokes 10 and the inner spokes 20 are spaced apart along the axial direction, and there is a cavity structure between them. This can reduce the material of the wheel hub spokes and the total weight of the wheel while reducing bending and torsional stress, thereby reducing the material cost of the wheel and contributing to vehicle lightweighting.

[0044] The inner spokes 20 and outer spokes 10 of the double-layer structure form a first cavity 40. The outer air vents 121 on the outer spokes 10 and the inner air vents 221 on the inner spokes 20 are connected to the first cavity 40. In this way, multiple outer air vents 121 and multiple inner air vents 221 are interconnected through the first cavity 40. Thus, the inside of the wheel rim 30 is connected to the outside through the inner air vents 221, the first cavity 40, and the outer air vents 121, realizing air circulation. This can effectively realize heat exchange between the wheel and the outside air, improving heat dissipation efficiency. Compared with the existing technology where the inner air vents 221 and the outer air vents 121 are connected one-to-one, this can improve the efficiency of heat exchange.

[0045] Furthermore, this embodiment does not specifically limit the relative positional relationship between the inner air hole 221 and the outer air hole 121. In actual installation, the inner air hole 221 and the outer air hole 121 can be set to be opposite or staggered. In this way, compared with the existing technology where the inner air hole 221 and the outer air hole 121 are connected in a one-to-one correspondence, the production process is simplified and the machining accuracy requirements of the outer wheel spoke 10 and the inner wheel spoke 20 are reduced. In actual installation, only the accuracy of the connection structure between the outer wheel spoke 10 and the inner wheel spoke 20 needs to be considered, which can effectively improve production efficiency.

[0046] It should be noted that this embodiment does not specifically limit the number or shape of the external air vent 121 and the internal air vent 221. In actual design, the shape of the air vent can be set to a direction, a circle, a triangle or other irregular shape, and the number of air vents can be set to 2, 3 or more. The number of internal air vents 221 and external air vents 121 can be set to be the same or different (for example, the number of internal air vents 221 is greater than the number of external air vents 121), as long as the external air vents 121 and internal air vents 221 are connected through the first cavity 40.

[0047] In this embodiment, the connection structure between the inner spokes 20 and the outer spokes 10 is not specifically limited. In actual installation, the inner spokes 20 and the outer spokes 10 can be directly connected. For example, the inner edge of the outer spokes 10 can be configured as a structure bent towards the inner spokes 20, and then the bent structure can be welded to the inner spokes 20. Similarly, the inner edge of the inner spokes 20 can also be configured as a bent structure facing the outer spokes 10. The connection between the inner edges of the inner spokes 20 and the outer spokes 10 can also be achieved through external connectors, such as riveting or welding with the addition of intermediate components.

[0048] As can be seen, during the assembly of the wheel in this embodiment, there is no relative positional relationship between the outer air hole 121 and the inner air hole 221, which reduces the assembly accuracy requirements, simplifies the production process, and improves production efficiency. In addition, the multiple outer air holes 121 and the multiple inner air holes 221 form a mutually penetrating structure, which improves the heat dissipation efficiency of the wheel through the outer air holes 121 and the inner air holes 221.

[0049] In one embodiment of this utility model, the inner edge of the center hole of at least one of the inner spokes and the outer spokes is bent toward the other to form a bent portion, and the inner spokes and the outer spokes are connected through the bent portion.

[0050] In this embodiment, the inner and outer spokes are directly connected without the need for intermediate components. In actual production, the center of the inner or outer spoke can be stamped to form a bend at the edge of the center hole of the inner or outer spoke. The inner and outer spokes are directly connected by the connection of the bends, resulting in a stronger connection.

[0051] In actual design, the inner spokes and the outer spokes can have bends on only one of them, or both of them can have bends.

[0052] As one embodiment of this utility model, see the appendix. Figure 4 , 5The outer spoke 10 has a first center hole 114 formed at its center, and the inner spoke 20 has a second center hole 212 formed at its center. The wheel includes a center connecting cylinder 50, the two ends of which are fixedly connected to the first mounting plate 11 and the second mounting plate 21, respectively, and the first center hole 114 and the second center hole 212 are connected. The rim 30, the outer spoke 10, the inner spoke 20 and the center connecting cylinder 50 together define the first cavity 40.

[0053] In this embodiment, the inner spokes 20 and the outer spokes 10 are connected by a central connecting cylinder 50. The specific structure of the central connecting cylinder 50 is not specifically limited in this embodiment. For example, the central connecting cylinder 50 can have a tubular structure or a cylindrical structure with a sealed bottom. It should be noted that when the central connecting cylinder 50 is a cylindrical structure with a sealed bottom, no through holes are provided on the outer spokes 10 at positions opposite to the central connecting cylinder 50, and the sealed bottom of the central connecting cylinder 50 faces the outer spokes 10.

[0054] In this embodiment of the invention, no special limitation is made on how to achieve the "fixed connection" of the central connecting cylinder 50. For example, the two ends of the central connecting cylinder 50 can be welded to the outer spoke 10 and the inner spoke 20 respectively.

[0055] It should be noted that, in order to improve the efficiency of the connection between the central connecting cylinder 50 and the inner spokes 20 and the outer spokes 10, a positioning flange 213 protruding towards the outer spokes 10 can be provided on the inner edge of the second central hole 212 of the inner spokes 20. (See Appendix) Figure 7 The positioning flange 213 and the central connecting cylinder 50 can be sleeved together. The central connecting cylinder 50 is sleeved on the outside of the positioning flange 213. During assembly, the central connecting cylinder 50 is pre-positioned by the positioning flange 213, and then the central connecting cylinder 50 is welded to the inner spoke 20 and the outer spoke 10 respectively. The pre-positioning function of the positioning flange 213 can improve the assembly efficiency and the stability of the assembly.

[0056] In this embodiment, when the wheel is used on a vehicle, the torque transmitted from the wheel axle first acts on the central connecting cylinder 50 when the vehicle is driving and turning, and then applies force to the outer spokes 10 and the inner spokes 20, thereby driving the outer rim 30 to rotate. During this process, the central connecting cylinder 50 applies a main radial force to the outer spokes 10 and the inner spokes 20 respectively, so that the thin-walled outer spokes 10 and the inner spokes 20 do not have to bear too much torque, which can significantly improve the lateral stiffness of the wheel and extend the service life of the wheel.

[0057] As one embodiment of this utility model, see the appendix. Figure 2-4 , Figure 6 and Figure 7 ,7.1 The outer spoke 10 includes a first mounting plate 11 and a first support portion 12. The first support portion 12 is arranged around the first mounting plate 11. The outer side of the first support portion 12 is connected to the inner wall of the rim 30. The first mounting plate 11 has a first center hole 114 formed in its center. The first mounting plate 11 is connected to the inner spoke 20. The first support portion 12 has an outer air hole 121 formed on it. The outer surface of the first support portion 12 is connected to the outer surface of the first mounting plate 11.

[0058] In this embodiment, the first mounting plate 11 is used to connect to the wheel hub, from... Figure 2 , 4 As can be seen from the figure, the end face of the first mounting plate 11 in this embodiment is set as a planar structure, which facilitates the docking of the first mounting plate 11 with the wheel hub and can improve the stability of the connection of the connecting parts.

[0059] Furthermore, in this embodiment, the outer surface of the inner side of the first support portion 12 protrudes outward along the axial direction of the rim 30 from the outer surface of the first mounting plate 11, which is equivalent to forming a recess (equivalent to a countersunk hole) at the center of the outer spoke 10. It should also be noted that the fact that the outer surface of the inner side of the first support portion 12 protrudes outward along the axial direction of the rim 30 from the outer surface of the first mounting plate 11 does not mean that the outer surface of the first support portion 12 is always inside the axial direction of the rim 30 relative to the outer surface of the first support portion 12. In actual installation, the surface of the first support portion 12 can be set as a convex and concave structure (to increase the structural strength and aesthetics of the outer spoke 10 itself). The recess formed here refers to the formation of a ring of protrusions at least at the edge of the central connecting portion.

[0060] Of course, in the design and setup, the outer surface of the first mounting plate can also be set to be flush with the outer surface of the first support or protrude outward from the outer surface of the first support.

[0061] In this embodiment, the recess depth of the first mounting plate 11 is not specifically limited; the recess depth can be very small, as shown in the attached figure. Figure 7 As shown, the inwardly recessed structure of the first mounting plate 11 in this manner is easy to process; the first mounting plate 11 can also have a larger recess depth relative to the first support portion 12, as shown in the attached figure. Figure 3 , 5As shown, when the recess depth is large, during the assembly of the wheel and hub in this embodiment, the ends of the connecting parts (such as bolts) can be prevented from protruding from the outer side of the wheel, thus improving the overall appearance of the wheel. In actual installation, to further improve the overall appearance of the wheel, a cover plate covering the first mounting plate 11 can be provided on the outer side of the outer spoke 10. This can hide the connecting parts, improving both safety protection and aesthetics.

[0062] In actual production, the wheel of this embodiment can be stamped at the center of the outer spoke 10 to form the first mounting plate 11 in this embodiment. The first mounting plate 11 and the first support part 12 are essentially an integral structure, which can effectively ensure the overall strength of the outer spoke 10.

[0063] As one embodiment of this utility model, see the appendix. Figure 2 , 4 The first support portion 12 has a plurality of recesses 122 formed at its inner edge, which are distributed around the axis of the rim 30. The first mounting plate 11 includes a center plate 111 and a radial extension plate 112. The center plate 111 has a first center hole 114. The radial extension plate 112 protrudes radially from the outer side wall of the center plate 111 along the rim 30 and corresponds one-to-one with the recesses 122. The radial extension plate 112 is disposed in the corresponding recesses 122. The outer surfaces of the center plate 111 and the radial extension plate 112 are on the same plane.

[0064] In this embodiment, by setting the groove 122 and the radial extension plate 112, the radial extension plate 112 is inserted into the groove 122, making the first support part 12 and the central connection part more tightly connected, thus improving the overall strength of the wheel; in addition, the first mounting plate 11 has a radial structure, making the wheel more stylish and improving its aesthetics.

[0065] In this embodiment, the outer surfaces of the first mounting plate are on the same plane, so the mounting through holes are opened on the plane, which is convenient for processing. Moreover, when welding with the connecting sleeve, the planar structure can reduce welding stress and improve the overall strength of the wheel.

[0066] As one embodiment of this utility model, see the appendix. Figure 4 The first support portion 12 includes an outer support section 123 and an inner support section 124. The inner side of the outer support section 123 and the outer side of the inner support section 124 are connected to form a raised transition portion 125. The raised transition portion 125 protrudes outward along the axial direction of the rim 30 and onto the outer surfaces of the outer support section 123 and the inner support section 124. The outer air hole 121 penetrates the outer support section 123.

[0067] In this embodiment, the first support portion 12 is configured with a structure that protrudes from the middle to both sides. This structure of the outer wheel spoke 10 has high structural strength, which can improve the strength of the wheel itself. In addition, in this embodiment, the outer air hole 121 is set in the outer support section 123. In this way, the axis of the outer air hole 121 is offset from the axis of the wheel. During driving (the driving direction of the vehicle is orthogonal to the axis of the wheel), the external air can more easily enter the wheel through the outer air hole 121 and exchange heat with the wheel, thereby improving the air flow efficiency and heat dissipation efficiency.

[0068] Of course, in actual design, the first support part can also be set as a structure on the same plane, or the whole can be formed as a structure where the outer edge of the outer spoke is higher than the inner edge.

[0069] As one embodiment of the present invention, the inner spoke 20 of the present invention includes a second mounting plate 21 and a second support portion 22. The second support portion 22 is arranged around the second mounting plate 21. The outer side of the second support portion 22 is connected to the inner wall of the rim 30. The inner air hole 221 is formed on the second support portion 22. The first mounting plate 11 and the second mounting plate 21 are opposite to each other and connected to each other.

[0070] In this embodiment, a first mounting plate 11 and a second mounting plate 21 are provided to cooperate with each other. The inner surface of the second mounting plate 21 is also set as a planar structure. In this way, the first mounting plate 11 and the second mounting plate 21 cooperate with each other, which facilitates the assembly and connection of the inner and outer spokes 10 and can improve the stability of the connection.

[0071] To further improve wheel rigidity, see Appendix Figure 1 , 3 6, 8. In one embodiment of the present invention, the wheel includes a plurality of connecting sleeves 60. The outer spoke 10 has a plurality of mounting through holes 113 formed around the axis of the rim 30. The inner spoke 20 has connecting through holes 211 that correspond one-to-one with the mounting through holes 113. The plurality of connecting sleeves 60 are fixedly disposed between the outer spoke 10 and the inner spoke 20. The two ends of the connecting sleeves 60 are fixedly connected to the outer spoke 10 and the inner spoke 20 respectively, and the mounting through holes 113 and the corresponding connecting through holes 211 are connected.

[0072] When the wheel is fixedly connected to the axle, fasteners are installed through the space and fixed to the axle. When the vehicle turns, the torque transmitted from the axle first acts on the connection between the connecting through hole 211 and the corresponding mounting through hole 113, and then applies a force to the outer spoke 10 and the inner spoke 20, thereby driving the outer rim 30 to rotate. During this process, the connection between the connecting through hole 211 and the mounting through hole 113 applies a main radial force to the outer spoke 10 and the inner spoke 20, respectively. As a result, the thin-walled outer spoke 10 and the inner spoke 20 do not have to bear excessive torque, which can significantly improve the lateral stiffness of the wheel and extend the service life of the wheel.

[0073] In this invention, the outer spokes 10 and the inner spokes 20 are axially distributed, so that when the wheel twists, the force borne by each individual spoke component (outer spoke 10, inner spoke 20) is mainly radial, and no large lateral torque is generated on the individual spoke component, thereby ensuring the lateral stiffness of the wheel, ensuring that the wheel can withstand the torque acting on the wheel when the vehicle turns, and extending the service life of the wheel.

[0074] Furthermore, the outer spokes 10 and the inner spokes 20 are spaced apart along the axial direction, forming a first cavity 40 between them. This reduces the material of the wheel hub spokes and the total weight of the wheel while reducing bending and torsional stress, thereby reducing the material cost of the wheel and contributing to vehicle lightweighting.

[0075] As one embodiment of this utility model, see the appendix. Figure 10 The connecting sleeve 60 includes a sleeve body 63 and a first positioning boss 61. The first positioning boss 61 is disposed on the outer wall surface of the sleeve body 63 and is located at the end of the connecting sleeve 60 that mates with the outer spoke 10. The first positioning boss 61 protrudes radially from the outer edge of the mounting through hole 113. The first positioning boss 61 abuts against the outer spoke 10 on the outside of the outer spoke 10, or the first positioning boss 61 abuts against the outer spoke 10 on the inside of the outer spoke 10.

[0076] See appendix Figure 1 , 3 as well as Figures 8 to 11 The connecting sleeve 60 includes a sleeve body 63 and a second positioning boss 62. The second positioning boss 62 is disposed on the outer wall surface of the sleeve body 63 and is located at the end of the connecting sleeve 60 that mates with the inner spoke 20. The second positioning boss 62 protrudes radially from the outer edge of the connecting through hole 211. The second positioning boss 62 abuts against the inner spoke 20 on the outside of the inner spoke 20, or the second positioning boss 62 abuts against the inner spoke 20 on the inside of the inner spoke 20.

[0077] In this embodiment, the main body of the connecting sleeve 60 passes through the first cavity 40. Both ends of the connecting sleeve 60 are connected to the inner spoke 20 and the outer spoke 10, respectively. In actual production, to improve assembly efficiency and the accuracy of the connecting sleeve 60's positioning, a protruding first positioning boss 61 can be provided on the outer wall of the connecting sleeve 60, as shown in the attached figure. Figure 8 , 9 As shown in Figure 10, during production, the first positioning boss 61 is used to mate with the edge of the mounting through hole 113 on the outer spoke 10 to define the axial relative position of the connecting sleeve 60 and the outer spoke 10; in addition, a second positioning boss 62 that mates with the inner spoke 20 can also be provided, see Appendix Figure 10 , 11 The second positioning boss 62 is used to define the relative position of the connecting sleeve 60 and the inner spoke 20 in the axial direction.

[0078] It should be noted that in actual design, only one of the first positioning boss 61 and the second positioning boss 62 on the connecting sleeve 60 needs to be designed, for example... Figure 11 The connecting sleeve 60 has no first positioning boss 61. Of course, the connecting sleeve 60 can also be designed to have only the first positioning boss 61 and no second positioning boss 62.

[0079] As one embodiment of the present invention, along the axial direction of the rim 30, the outer air hole 121 communicates with at least one of the inner air holes 221.

[0080] In this embodiment, the number of inner air holes 221 on the wheel can be greater than the number of outer air holes 121. In the axial direction of the rim 30, each outer air hole 121 has an inner air hole 221 that communicates with it. In this way, the inner air holes 221 can be directly seen through the outer air holes 121 along the axial direction of the wheel.

[0081] In actual installation, each external air vent 121 can be interconnected with an internal air vent 221 (as shown in the attached diagram). Figure 2 It can also communicate with multiple inner air holes 221 at the same time, depending on the diameter of the outer air hole 121 and the inner air hole 221 and the relative positional relationship between the outer wheel spoke 10 and the inner wheel spoke 20.

[0082] Of course, see appendix. Figure 2 In actual installation, the inner air hole 221 and the outer air hole 121 can be configured as a one-to-one correspondence structure. During installation, when the inner wheel spoke 20 and the outer wheel spoke 10 are installed, the inner air hole 221 and the outer air hole 121 are aligned, which can improve the overall appearance of the wheel.

[0083] As one embodiment of this utility model, see the appendix. Figure 7 , 7.1Along the axial direction of the rim 30, the outer air hole 121 and the inner air hole 221 are not connected. At this time, along the axial direction of the wheel, the inner air hole 221 cannot be directly seen through the outer air hole 121.

[0084] As one embodiment of this utility model, see the appendix. Figure 1 The outer spoke 10 includes a flange 13 that folds from the edge of the outer air vent 121 toward the inner spoke 20. This makes the inner wall of the thin-walled component (outer spoke 10) invisible from the outside, improving the overall appearance of the wheel.

[0085] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model 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 this utility model will be included within the scope of the claims.
