[0031] Schematic diagram of the easy-to-clean wheel hub,

[0032] refer to Figures 2 to 7 According to a preferred embodiment of the present invention, a wheel hub that is easy to clean includes a spoke 10, a rim 20 and an inner wall cleaning member 30.

[0033] Specifically, if Figure 3As shown, the rim 20 has a through hole 201, the spoke 10 is located at one end of the through hole 201 and is fixedly connected to the rim 20, and the fixed connection method includes but is not limited to welding. The end surface of one end of the spoke 10 and the hole wall of the through hole 201 together form a receiving cavity 202, as shown in FIG. Figure 4 As shown, the spoke 10 has a concave surface 101 at one end close to the opening of the accommodating cavity 202, and the concave surface 101 has a plurality of raised portions 102 arranged in a ring shape, and each of the raised portions 102 is provided with a through connecting hole 1021; the inner wall cleaning component 30 includes a plurality of branch pipe portions 301 arranged in a ring array, and a branch pipe portion 301 is provided on the concave surface 101 between two adjacent raised portions 102, and the distance between the raised portion 102 and the concave surface 101 is greater than the thickness of the branch pipe portion 301.

[0034] It should be noted that, during installation, the connection hole 1021 on the spoke 10 is connected to the external hub motor by bolts. In order to avoid interference between the branch pipe portion 301 and the external hub motor during installation, the present application provides the concave surface 101, and extends the convex portion 102 from the concave surface 101 toward the cavity opening of the accommodating cavity 202 by a predetermined distance, and makes the distance between the convex portion 102 and the concave surface 101 greater than the thickness of the branch pipe portion 301. When the external hub motor is bolted to the spoke 10, the end face of the external hub motor abuts against the convex portion 102, and the branch pipe portion 301 is spaced a predetermined distance from the convex portion 102, thus avoiding interference between the branch pipe portion 301 and the convex portion 102 during installation. 01 Interference problem with the external hub motor; in addition, when cleaning the hub, the side of the spoke 10 facing away from the opening of the accommodating cavity 202 is exposed, so the cleaning staff can directly apply the deironing powder spray and then rinse its surface with a water gun. When cleaning the inner wall of the spoke 10, that is, the side of the spoke 10 close to the opening of the accommodating cavity 202, a solution doped with deironing powder is injected into each of the branch pipe parts 301, and the solution flows along the branch pipe part 301 to the inner wall surface of the spoke 10, and then clean water is injected into each of the branch pipe parts 301 to achieve the cleaning of the inner wall of the spoke 10; it is obvious that compared with the prior art, the present application has the advantages of facilitating the cleaning of the inner wall of the spoke and helping to increase the service life of the hub.

[0035] Furthermore, in order to realize the connection of multiple branch pipes 301, as shown in FIG. Figure 4 As shown, the spoke 10 also has a central hole 103. Figure 5 and Figure 6As shown, the inner wall cleaning part 30 also includes an annular body portion 302, one end of the annular body portion 302 is penetrated by the central hole 103, and the branch pipe portions 301 are arranged in an annular array around the central axis of the annular body portion 302, and the annular body portion 302 has a first chamber 3021, and each of the branch pipe portions 301 has a second chamber 3011, each of the branch pipe portions 301 is fixedly connected to the annular body portion 302, and the first chamber 3021 is communicated with each of the second chambers 3011.

[0036] It should be noted that during cleaning, the cleaning staff injects cleaning liquid into the annular portion 302 , and the cleaning liquid flows along the first chamber 3021 to the second chamber 3011 , and is discharged from one end of the branch portion 301 away from the annular portion 302 .

[0037] Further, if Figure 3 and Figure 4 As shown, the spoke 10 has a convex arc surface 104 at one end close to the opening of the accommodating cavity 202. In order to fully flush the convex arc surface 104, as shown in FIG. Figure 2 and Figure 5 As shown, the branch portion 301 includes a welding portion 3012 and a bending portion 3013. The welding portion 3012 is placed on the concave surface 101 between the two adjacent raised portions 102. The welding portion 3012 is welded to the concave surface 101. The bending portion 3013 is located at one end of the welding portion 3012 away from the ring body portion 302, and the bending portion 3013 is arranged at an angle to the welding portion 3012. The bending portion 3013 is close to the convex arc surface 104.

[0038] In addition, in the embodiment of the present application, the number of the branch pipe portions 301 is five. In order to achieve comprehensive flushing of the convex curved surface 104, the end of the bent portion 3013 away from the welding portion 3012 and the two side walls of the bent portion 3013 are provided with water outlets (not marked in the figure), and the water outlets are connected to the second chamber 3011. Specifically, Figure 5 As shown, the two side walls of the bending portion 3013 have two inclined extension forks 3014. When the fluid enters the branch portion 301, the fluid can be discharged outward along the two extension forks 3014 and the end of the branch portion 301.

[0039] In addition, if Figure 5As shown, the end of the ring body 302 away from the branch pipe portion 301 has several water inlets 3022, and the water inlets 3022 are connected to the first chamber 3021. It should be noted that in the embodiment of the present application, the number of the water inlets 3022 is five, and the five water inlets 3022 are arranged in a circular array to reduce the uneven water output caused by the overall circular shape of the ring body 302 and the first chamber 3021. The cleaning staff can inject cleaning liquid into each of the water inlets 3022 one by one, and the two branch pipe portions 301 closest to the corresponding water inlets 3022 will flow out the most cleaning liquid to rinse the convex arc surface 104 of the corresponding area.

[0040] In addition, in order to avoid less fluid flowing to the extension fork 3014, as shown in FIG. Figure 7 As shown, the second chamber 3011 has two stopper portions 3015 at one end away from the annular body portion 302, and the two stopper portions 3015 are symmetrically arranged and located on both sides of the second chamber 3011. The two stopper portions 3015 have an inclined surface 3016 on the opposite sides, so that the cross-sectional area of ​​the end portion of the second chamber 3011 away from the annular body portion 302 gradually decreases. At the same time, each of the stopper portions 3015 has a guiding arc surface 3017 at one end close to the annular body portion 302. When the fluid flows through the stopper portion 3015, a part of the fluid is blocked by the guiding arc surface 3017 of the stopper portion 3015 and flows along the guiding arc surface 3017 to the extended fork 3014.

[0041] Furthermore, since an external brake disc is also placed in the accommodating chamber 202, in order to realize heat exchange between the external brake disc and the outside air, Figure 3 and Figure 4 As shown, the spoke 10 further has a plurality of heat dissipation holes 105 , the connection hole 1021 is located outside the central hole 103 , and the heat dissipation holes 105 are located outside the connection hole 1021 and are arranged in a ring array.

[0042] In summary, the easy-to-clean wheel hub according to the embodiment of the present application is explained, which provides the easy-to-clean wheel hub with advantages such as easy cleaning of the inner wall of the spokes and helping to increase the service life of the wheel hub.

[0043] It is worth mentioning that in the embodiments of the present application, the easy-to-clean wheel hub has a simple structure, does not involve complex manufacturing processes and expensive materials, and is highly economical. Furthermore, for manufacturers, the easy-to-clean wheel hub provided by the present application is easy to produce and is low-cost, which is more conducive to controlling production costs and further promoting product promotion and use.
