[0002] Wheel hub packaging materials, as a packaging equipment for facilitating the transportation and handling of wheel hubs, have been widely used in major car factories. In order to avoid damage to the wheel hubs during packaging, wheel hub packaging materials are generally packaged with high-density composite materials, such as high-density polyethylene. Since the hardness of these materials is much lower than that of the wheel hubs, and at the same time, this material has the characteristics of high strength, light weight, easy manufacturing and low manufacturing cost, it is easier to package the wheel hubs and transport them.

[0003] However, the inventors have found that since most of the current packaging materials can only package wheels of one size, once wheels of multiple sizes need to be packaged at the same time, additional molds need to be opened for production and manufacturing, which undoubtedly increases the manufacturing cost. Utility Model Content

[0004] The purpose of the implementation mode of the utility model is to design a wheel hub upper positioning structure, a wheel hub lower positioning structure, a partition and a wheel hub packaging material, which can respectively meet the packaging requirements of two sizes of wheels, thereby reducing the production cost of the wheel hub packaging material.

[0005] In order to achieve the above-mentioned purpose, an embodiment of the utility model provides a hub upper positioning structure, wherein the hub upper positioning structure is arranged on the top side of the partition of the hub packaging material, and the hub upper positioning structure comprises:

[0006] An upper positioning groove is provided on the top side of the partition plate and is used to be embedded by the first end face of the wheel hub; the groove wall of the upper positioning groove is a first upper positioning surface that fits with the outer ring of the wheel rim of the wheel hub;

[0007] A boss is arranged in the upper positioning groove and is coaxially arranged with the upper positioning groove; the boss is used to enter the cavity of the wheel hub when the first end face of the wheel hub is embedded in the upper positioning groove; one side of the boss relative to the first upper positioning surface is a second upper positioning surface that can fit with the inner ring of the wheel rim of the wheel hub;

[0008] Wherein, when the first upper positioning surface is in contact with the outer ring of the wheel rim of the wheel hub, the second upper positioning surface is separated from the inner ring of the wheel rim of the wheel hub;

[0009] When the second upper positioning surface is in contact with the inner ring of the wheel rim of the wheel hub, the first upper positioning surface is separated from the outer ring of the wheel rim of the wheel hub.

[0010] In addition, an embodiment of the utility model provides a wheel hub lower positioning structure, which is arranged on the bottom side of the partition of the wheel hub packaging material, and the wheel hub lower positioning structure includes:

[0011] A lower positioning groove is provided on the bottom side of the partition plate and is used to be embedded by the second end face of the wheel hub; the groove wall of the lower positioning groove is a first lower positioning surface that fits with the outer ring of the wheel rim of the wheel hub;

[0012] A plurality of positioning protrusions are arranged around the axis of the lower positioning groove on the bottom side of the partition, and each of the positioning protrusions surrounds the axis of the lower positioning groove to form a positioning space that can be embedded in the second end face of the hub, and each of the positioning protrusions has a second lower positioning surface that can fit with the outer ring of the wheel rim of the hub;

[0013] Wherein, when the lower positioning groove is embedded by the second end surface of the wheel hub, the first lower positioning surface is fitted with the outer ring of the wheel rim of the wheel hub;

[0014] When the positioning space is embedded by the second end surface of the wheel hub, the second lower positioning surface of each positioning protrusion fits with the outer ring of the wheel rim of the wheel hub.

[0015] In addition, an embodiment of the utility model further provides a partition, the partition having a top side and a bottom side opposite to the top side, the top side is provided with at least one hub upper positioning structure as described above, and the bottom side is provided with at least one hub lower positioning structure as described above;

[0016] The number of the upper hub positioning structures is the same as the number of the lower hub positioning structures, and they are uniquely arranged. The upper hub positioning structures and the lower hub positioning structures are respectively used to position different hubs.

[0017] In addition, an embodiment of the present utility model provides a wheel hub packaging material, including: at least one partition as described above.

[0018] Compared with the prior art, the embodiments of the utility model have a hub positioning structure of the partition plate arranged on the top side of the partition plate, and the hub positioning structure includes: an upper positioning groove and a boss arranged on the top side of the partition plate, wherein the groove wall of the upper positioning groove is a first upper positioning surface that fits with the outer ring of the rim of the hub, and secondly, the boss is coaxially arranged with the upper positioning groove, and at the same time, the boss can directly enter the cavity of the hub when the first end face of the hub is embedded in the upper positioning groove, and the side of the boss relative to the first upper positioning surface is a second upper positioning surface that can fit with the inner ring of the rim of the hub, therefore, hubs of different sizes can be positioned respectively through the first upper positioning surface and the second upper positioning surface, so that the partition plate can meet the packaging positioning requirements of two different sizes of hubs respectively, thereby reducing the production cost of the hub packaging material.

Therefore, wheel hubs of different sizes can also be positioned respectively through the first lower positioning surface and each second lower positioning surface. As a result, the partition can meet the packaging positioning requirements of two sizes of wheel hubs respectively, thereby reducing the production cost of the wheel hub packaging material.

[0020] When multiple wheel hubs need to be packaged, one of the partitions can be used to support the first end face of the wheel hub so that the first end face of the wheel hub can be directly embedded in the upper positioning groove of the partition. At the same time, another partition cover is set on the second end face of the wheel hub so that the second end face of the wheel hub can be directly embedded in the lower fixed groove of the partition or embedded in the positioning space of the partition. Therefore, by arranging multiple partitions in sequence from bottom to top, the packaging needs of multiple wheel hubs can be met at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those skilled in the art that in each embodiment of the present invention, many technical details are provided to enable readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can be implemented.

[0027] Embodiment 1

[0028] The first embodiment of the utility model relates to a positioning structure on a wheel hub, such as Figure 1 As shown, the wheel hub upper positioning structure 11 is arranged on the top side 12 of the partition 1 of the wheel hub packaging material, and the wheel hub upper positioning structure 11 includes: an upper positioning groove 111 and a boss 112 .

[0029] Wherein, in some embodiments, Figure 1 , Figure 3 and Figure 4 As shown, the upper positioning groove 111 is arranged on the top side 12 of the partition 1, and the upper positioning groove 111 is used to be embedded in the first end face 101 of the hub 10, and the groove wall of the upper positioning groove 111 is a first upper positioning surface 113 that fits with the rim outer ring 102 of the hub 10.

[0030] Second, in some embodiments, Figure 1 As shown, the boss 112 is arranged in the upper positioning groove 111, and the boss 112 is coaxially arranged with the upper positioning groove 111. The boss 112 is used to enter the cavity 103 of the hub 10 when the first end face 101 of the hub 10 is embedded in the upper positioning groove 111, and the side of the boss 112 relative to the first upper positioning surface 113 is a second upper positioning surface 114 that can fit with the inner ring 104 of the rim of the hub 10.

[0031] When the first upper positioning surface 113 is in contact with the rim outer ring 102 of the wheel hub 10, the second upper positioning surface 114 is separated from the rim inner ring 104 of the wheel hub 10. When the second upper positioning surface 114 is in contact with the rim inner ring 104 of the wheel hub 10, the first upper positioning surface 113 is separated from the rim outer ring 102 of the wheel hub 10.

[0032] It is not difficult to see from the above content that the hub positioning structure 11 of the partition 1 is arranged on the top side 12 of the partition 1, and the hub positioning structure 11 includes: an upper positioning groove 111 and a boss 112 arranged on the top side 12 of the partition 1, wherein the groove wall of the upper positioning groove 111 is a first upper positioning surface 113 that fits with the rim outer ring 102 of the hub 10, and secondly, the boss 112 is coaxially arranged with the upper positioning groove 111, and at the same time, the boss 112 can directly enter the cavity 103 of the hub 10 when the first end face 101 of the hub 10 is embedded in the upper positioning groove 111, and the side of the boss 112 relative to the first upper positioning surface 113 is a second upper positioning surface 114 that can fit with the rim inner ring 104 of the hub 10. Therefore, wheel hubs 10 of different sizes can be positioned respectively through the first upper positioning surface 113 and the second upper positioning surface 114, so that the partition 1 can meet the packaging positioning requirements of two different sizes of wheel hubs 10 respectively, thereby reducing the production cost of the wheel hub packaging material.

[0033] Specifically, in some embodiments, Figure 3 and Figure 4 As shown in FIG. 1 , since the first upper positioning surface 113 of the upper positioning groove 111 can be fitted with the rim outer ring 102 of the wheel hub 10, and the second upper positioning surface 114 of the boss 112 can be fitted with the rim inner ring 104 of the wheel hub 10, the first upper positioning surface 113 can be used to position the wheel hub 10 of a large size, as shown in FIG. Figure 3 The state shown in FIG. 1 is shown in FIG. 1 , and the small-sized wheel hub 10 can be positioned by the second upper positioning surface 114, as shown in FIG. Figure 4 Also, it is worth noting that, in some embodiments, the first upper positioning surface 113 is a continuous circular surface. Alternatively, in other embodiments, such as Figure 1 As shown, the first upper positioning surface 113 includes: a plurality of arcuate surfaces 1131 formed by interrupting the axis of the upper positioning groove 111. Moreover, when the first upper positioning surface 113 includes: a plurality of arcuate surfaces 1131 formed by interrupting the axis of the upper positioning groove 111, each arcuate surface 1131 is equidistantly arranged around the axis of the upper positioning groove 111, thereby increasing the contact area between the first upper positioning surface 113 and the rim outer ring 102 of the wheel hub 10, so that the wheel hub 10 has a better positioning effect in the upper positioning groove 111. Moreover, as a preferred solution, in other embodiments, such as Figure 1 As shown, the first upper positioning surface 113 of the upper positioning groove 111 is gradually extended from the top side 12 to the bottom side 14 toward the axial direction of the partition 1, so that the first upper positioning surface 113 is inclined along the axial direction of the partition 1, thereby ensuring that the upper positioning groove 111 has a larger notch. Therefore, whenever the wheel hub 10 needs to be positioned through the first upper positioning surface 113, the first end surface 101 of the wheel hub 10 can enter the upper positioning groove 111 more conveniently. In addition, in other embodiments, such as Figure 1 As shown, the wheel hub upper positioning structure 11 further includes: an upper support platform 115, and the upper support platform 115 is arranged in the upper positioning groove 111, and at the same time, the upper support platform 115 is also coaxially arranged with the boss 112, wherein the upper support platform 115 is located between the boss 112 and the groove bottom of the upper positioning groove 111, and the upper support platform 115 is used when the first end face 101 of the wheel hub 10 is embedded in the upper positioning groove 111, as shown in FIG. Figure 3 As shown, the upper support platform 115 abuts against the first end surface 101 of the hub 10. Therefore, the support performance of the upper support platform 115 can be improved by the upper support platform 115 abutting against the first end surface 101 of the hub 10.

[0034] Finally, while ensuring the positioning performance of the boss 112 on the hub 10, in order to facilitate the formation of the boss 112 on the partition 1, in other embodiments, such as Figure 1 and Figure 3As shown, the boss 112 can be formed by the upper support platform 115, which is away from the side of the bottom of the upper positioning groove 111, with a portion protruding toward the top side 12 of the partition 1, so that the boss 112 and the partition 1 are formed integrally, thereby ensuring the strength of the boss 112 on the partition 1. In addition, since the formation of the boss 112 does not add any components to the partition 1, the weight of the partition 1 will not be increased, thereby facilitating the user to carry and transport the packaged wheel hub 10.

[0035] Similarly, in order to ensure the supporting performance of the upper support platform 115 for the wheel hub 10 while facilitating the formation of the support platform 115 on the partition 1, in some embodiments, the upper support platform 5 is formed by partially protruding the bottom of the upper positioning groove 111 toward the top side 12 of the partition 1, so that the upper support platform 5 and the partition 1 are formed integrally, which ensures the strength of the upper support platform 5 on the partition 1 while ensuring the supporting performance of the upper support platform 5 for the wheel hub 10.

[0036] Embodiment 2

[0037] The second embodiment of the utility model relates to a hub lower positioning structure, such as Figure 2 As shown, the wheel hub lower positioning structure 13 is disposed on the bottom side 14 of the partition 1 of the wheel hub packaging material, and the wheel hub lower positioning structure 13 includes: a lower positioning groove 131 and a plurality of positioning protrusions 132 .

[0038] Wherein, in some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, the lower positioning groove 131 is arranged on the bottom side 14 of the partition 1, and the lower positioning groove 131 is used to be embedded in the second end face 105 of the hub 10, and the groove wall of the lower positioning groove 131 is a first lower positioning surface 133 that fits with the rim outer ring 102 of the hub 10.

[0039] Second, in some embodiments, Figure 2 As shown, each positioning protrusion 132 is formed on the bottom side 14 of the partition 1 around the axis of the lower positioning groove 131, and each positioning protrusion 132 is surrounded by the axis of the lower positioning groove 131 to form a positioning space (not marked in the figure) that can be embedded in the second end face 105 of the hub 10, and each positioning protrusion 132 has a second lower positioning surface 134 that can fit with the outer ring of the rim of the hub.

[0040] When the lower positioning groove 131 is embedded in the second end face 105 of the wheel hub 10, the first lower positioning surface 133 is in contact with the rim outer ring 102 of the wheel hub 10. When the positioning space is embedded in the second end face 105 of the wheel hub 10, the second lower positioning surface 134 of each positioning protrusion 132 is in contact with the rim outer ring 102 of the wheel hub 10.

[0041] It is not difficult to see from the above content that the wheel hub lower positioning structure 13 of the partition 1 is arranged on the bottom side 14 of the partition 1, and the wheel hub lower positioning structure 13 includes: a lower positioning groove 131 and a plurality of positioning protrusions 132 arranged on the bottom side 14 of the partition 1, wherein the groove wall of the lower positioning groove 131 is a first lower positioning surface 133 that fits with the wheel rim outer ring 102 of the wheel hub 10, and secondly, each positioning protrusion 132 is arranged around the axis of the lower positioning groove 131 on the bottom side 14 of the partition 1, and each positioning protrusion 132 has a second lower positioning surface 134 that can fit with the wheel rim outer ring 102 of the wheel hub 10. Therefore, the wheel hubs 10 of different sizes can also be positioned respectively through the first lower positioning surface 133 and each second lower positioning surface 134, so that the partition 1 can meet the packaging positioning requirements of two sizes of wheel hubs 10 respectively, thereby reducing the production cost of the wheel hub packaging material.

[0042] Specifically, in some embodiments, Figure 3 and Figure 4 As shown in FIG. 1 , since the first lower positioning surface 133 of the lower positioning groove 131 can fit with the rim outer ring 102 of the wheel hub 10, and the second lower positioning surface 134 of each positioning protrusion 132 can also fit with the rim ring 104 of the wheel hub 10, the large-sized wheel hub 10 can be positioned by the first lower positioning surface 133, as shown in FIG. Figure 3 The state shown in FIG. 1 is shown in FIG. 1 , and the small-sized wheel hub 10 can be positioned by the second lower positioning surface 134 of each positioning protrusion 132, such as Figure 4 Also, it is worth noting that, in some embodiments, the first lower positioning surface 133 may be a continuous circular surface. Alternatively, in other embodiments, such as Figure 2 As shown, the first lower positioning surface 133 may also include: a plurality of arcuate surfaces 1331 formed by interrupting the axis of the lower positioning groove 131. Furthermore, when the first lower positioning surface 133 includes: a plurality of arcuate surfaces 1331 formed by interrupting the axis of the lower positioning groove 131, each arcuate surface 1331 is equidistantly arranged around the axis of the lower positioning groove 131, thereby increasing the contact area between the first lower positioning surface 133 and the rim outer ring 102 of the wheel hub 10, so that the wheel hub 10 has a better positioning effect in the lower positioning groove 131. Furthermore, as a preferred solution, in other embodiments, such as Figure 2 As shown, the first lower positioning surface 133 of the lower positioning groove 131 is inclined and extends gradually from the bottom side 14 to the top side 12 toward the axial direction close to the partition 1, so that the first lower positioning surface 133 is inclined along the axial direction of the partition 1, thereby ensuring that the lower positioning groove 131 has a larger notch. Therefore, whenever the wheel hub 10 needs to be positioned through the first lower positioning surface 133, the second end face 105 of the wheel hub 10 can enter the lower positioning groove 131 more conveniently.

[0043] Furthermore, based on the structural characteristics of the first lower positioning surface 133, in some embodiments, as Figure 2 As shown, the second lower positioning surface 134 of each positioning protrusion 132 may also be an arcuate surface that fits with the rim outer ring 102 of the wheel hub 10, thereby increasing the area where the second lower positioning surface 134 of each positioning protrusion 132 fits with the rim outer ring 102, thereby further improving the positioning performance of each positioning protrusion 132 on the wheel hub 10. Similarly, as a preferred solution, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the second lower positioning surface 134 of each positioning protrusion 132 is inclined and extends gradually from the bottom side 14 to the top side 12 toward the axial direction close to the partition 1, thereby ensuring that the positioning space surrounded by each positioning protrusion 132 has a larger opening. Therefore, when the partition 1 is covered on the second end surface 105 of the hub 10, the second end surface 105 of the hub 10 can enter the positioning space more conveniently.

[0044] Embodiment 3

[0045] The third embodiment of the present utility model relates to a partition, such as Figure 1 and Figure 2 As shown, the partition 1 has a top side 12 and a bottom side 14 opposite to the top side 12, wherein Figure 1 As shown, at least one hub upper positioning structure 11 as described in the first embodiment is provided on the top side 12. Figure 2 As shown, at least one under-hub positioning structure 13 as described in the second embodiment is disposed on the bottom side 14 .

[0046] Furthermore, the number of the upper hub positioning structures 11 is the same as the number of the lower hub positioning structures 13 , and they are uniquely arranged. Meanwhile, the upper hub positioning structures 11 and the lower hub positioning structures 13 are respectively used to position different hubs 10 .

[0047] It is not difficult to see from the above content that since the top side 12 and the bottom side 14 of the partition 1 are respectively provided with the upper hub positioning structure 11 described in Example 1 and the lower hub positioning structure 13 described in Example 2, one of the hubs 10 can be positioned by the upper hub positioning structure 11, and the other hub 10 can be positioned by the lower hub positioning structure 13, so that one partition 1 can meet the positioning requirements of two hubs 10 at the same time.

[0048] Specifically, in some embodiments, Figure 1 and Figure 2As shown, the boss 112 of the positioning structure 11 on the wheel hub is formed by squeezing the bottom side 14 of the partition 1 toward the top side 12, so that the boss 112 and the partition 1 are integrally formed. While not affecting the positioning of the wheel hub 10 by the boss 112, since no components are added to the partition 1, the weight of the partition 1 will not be increased, thereby facilitating the user to carry and transport the packaged wheel hub 10.

[0049] And, as a preferred solution, in other embodiments, such as Figure 1 and Figure 2 As shown, the side of the boss 112 facing away from the bottom side 14 of the partition 1 is partially extruded toward the top side 12, so that at least one reinforcing rib 116 is formed on the side of the boss 112 facing away from the top side 12. By forming the reinforcing rib 116 on the boss 112, the strength of the partition 1 can be further improved.

[0050] Embodiment 4

[0051] The fourth embodiment of the present utility model relates to a wheel hub packaging material, such as Figures 1 to 4 As shown, the wheel hub packaging material includes: at least one partition plate 1 as described in the third embodiment.

[0052] It is not difficult to see from the above content that when multiple wheel hubs 10 need to be packaged, one of the partitions 1 can be used to support the first end face 101 of the wheel hub 10, so that the first end face 101 of the wheel hub 10 can be directly embedded in the upper positioning groove of the partition 1, and at the same time, another partition 1 is covered on the second end face of the wheel hub 10, so that the second end face of the wheel hub can be directly embedded in the lower fixed groove of the partition or embedded in the positioning space of the partition. Therefore, by arranging multiple partitions in sequence from bottom to top, the packaging needs of multiple wheel hubs can be met at the same time.
