Description

Technical Field

[0001] The embodiments of this utility model relate to the field of wheel hub packaging, and particularly to a wheel hub positioning structure and partition. Background Technology

[0002] Wheel hub packaging materials, as a type of packaging equipment used to facilitate the transportation and handling of wheel hubs, are widely used by major automakers. To avoid damage to the wheel hubs during packaging, these materials are typically made of high-density composite materials, such as high-density polyethylene (HDPE). Because these materials are much softer than wheel hubs, and possess characteristics such as high strength, light weight, ease of manufacture, and low production cost, they are relatively easy to package and transport.

[0003] However, the inventors discovered that while some wheel packaging materials can position wheel hubs of two different sizes, due to design and manufacturing errors, the wheel hub will shift in a localized area after being positioned on the partition, regardless of the size. This displacement can cause unnecessary vibration and / or shaking during transportation after the wheel packaging material has packaged multiple wheel hubs. This vibration and / or shaking can lead to wear or damage to the surface of the wheel hub. Utility Model Content

[0004] The purpose of this invention is to design a wheel hub positioning structure and partition, which can meet the packaging requirements of two different sizes of wheel hubs, while also improving the positioning performance of the wheel hub after packaging, and avoiding unnecessary vibration and / or shaking of the wheel hub during transportation.

[0005] To achieve the above objectives, embodiments of this utility model provide a hub positioning structure, wherein the hub positioning structure is disposed on the top side of the partition of the hub cladding material, and the hub positioning structure includes:

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

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

[0008] When the first positioning surface is in contact with the outer rim of the wheel hub, the second positioning surface is partially separated from the inner rim of the wheel hub, and partially in contact with the inner rim of the wheel hub, so that the wheel hub is positioned in the upper positioning groove.

[0009] When the second positioning surface is in contact with the inner rim of the wheel hub, part of the first positioning surface is separated from the outer rim of the wheel hub, and another part is in contact with the outer rim of the wheel hub, so that the wheel hub is positioned in the upper positioning groove.

[0010] In addition, an embodiment of the present invention provides a partition having a top side and a bottom side opposite to the top side, and the partition is provided with at least one hub positioning structure as described above.

[0011] Compared with the prior art, the embodiments of this utility model have the following advantages: the wheel hub positioning structure includes a boss and an upper positioning groove surrounding the boss. The groove wall of the upper positioning groove is a first positioning surface that can fit with the outer ring of the wheel hub rim, and the side of the boss opposite to the first positioning surface is a second positioning surface that can fit with the inner ring of the wheel hub rim. The first positioning surface and the second positioning surface can respectively meet the packaging requirements of two different sizes of wheel hubs. At the same time, since the boss and the upper positioning groove are eccentrically set, when the outer ring of the rim of one size of wheel hub fits with the first positioning surface of the upper positioning groove, the second positioning surface of the boss can also partially fit with the inner ring of the rim of that size of wheel hub, thereby meeting the positioning requirements of the medium-sized wheel hub in the upper positioning groove. Similarly, when the inner rim of a wheel hub of another size is in contact with the second positioning surface of the boss, the first positioning surface of the upper positioning groove can be partially in contact with the outer rim of the wheel hub, thus satisfying the positioning requirements of the wheel hub of that size in the upper positioning groove. Since both the first and second positioning surfaces can be in contact with the outer and inner rims of the wheel hub respectively when positioning wheel hubs of different sizes, the uniqueness of the wheel hub's position on the partition is guaranteed, thereby preventing the wheel hub from shifting on the partition and the wheel hub from vibrating and / or shaking during transportation, thus reducing the probability of wheel hub wear or damage.

[0012] In summary, the eccentric design described in this article can accommodate the positioning of rims of various sizes, and the upper and lower layers are less prone to misalignment. In addition, the partition parts that contact the front and back of the wheel hub all adopt a large flat surface design. Because many concave and convex structures are reduced, no stress concentration will occur in any size rim, significantly reducing the risk of crushing damage. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0020] Example 1

[0021] The first embodiment of this utility model relates to a hub positioning structure, such as... Figure 1 , Figure 4 and Figure 5 As shown, the hub positioning structure 11 is disposed on the top side 12 of the partition 1 of the hub cladding material, and the hub positioning structure 11 includes: an upper positioning groove 111 and a boss 112.

[0022] In some embodiments, such as Figure 1 and Figure 2 As shown, the upper positioning groove 111 is provided on the top side 12 of the partition plate 1. The upper positioning groove 111 is used to be embedded in one side end face of the hub 10, and the groove wall of the upper positioning groove 111 is a first positioning surface that can fit with the outer ring 102 of the rim of the hub 10.

[0023] Secondly, in some embodiments, such as Figure 1 and Figure 2 As shown, the boss 112 is surrounded by the upper positioning groove 111, and the boss 112 is eccentrically positioned with the upper positioning groove 111. The boss 112 is used to enter the cavity 103 of the wheel hub 10 when one end face of the wheel hub 10 is embedded in the upper positioning groove 111. Furthermore, the side of the boss 112 relative to the first positioning surface 113 is a second positioning surface 114 that can fit with the inner ring 104 of the wheel rim of the wheel hub 10.

[0024] Among them, combined Figure 5 As shown, when the boss 112 enters the cavity 103 of the hub 10, the first positioning surface 113 and the second positioning surface 114 are at least partially attached to the outer rim 102 and the inner rim of the hub 10, respectively, so that the hub 10 is positioned in the upper positioning groove 111.

[0025] As can be seen from the above, the wheel hub positioning structure includes a boss 112 and an upper positioning groove 111 surrounding the boss 112. The groove wall of the upper positioning groove 111 is a first positioning surface 113 that can fit with the outer rim of the wheel hub. The side of the boss 112 opposite to the first positioning surface 113 is a second positioning surface 114 that can fit with the inner rim 104 of the wheel hub 10. The first positioning surface 113 and the second positioning surface 114 can respectively meet the packaging requirements of two different sizes of wheel hubs 10. Since the boss 112 and the upper positioning groove 111 are eccentrically set, when the outer rim 102 of one size of wheel hub 10 fits with the first positioning surface 113 of the upper positioning groove 111, the second positioning surface 114 of the boss 112 can also partially fit with the inner rim 104 of that size of wheel hub 10, thereby meeting the positioning requirements of that size of wheel hub 10 in the upper positioning groove 111. Similarly, when the inner rim 104 of a wheel hub 10 of another size is in contact with the second positioning surface 114 of the boss 112, the first positioning surface 113 of the upper positioning groove 111 can be partially in contact with the outer rim 102 of the wheel hub 10, thereby satisfying the positioning requirements of the wheel hub of this size in the upper positioning groove. Since the first positioning surface 113 and the second positioning surface 114 can be in contact with the outer rim 102 and the inner rim 104 of the wheel hub 10 respectively when positioning wheel hubs 10 of different sizes, the uniqueness of the position of the wheel hub 10 on the partition 1 is guaranteed, thereby preventing the wheel hub 10 from shifting on the partition 1 and the wheel hub 10 from vibrating and / or shaking during transportation, thus reducing the probability of wear or damage to the wheel hub.

[0026] Specifically, the wheel hub positioning structure in this embodiment can position two different sizes of wheel hubs 10, for example, such as Figure 1 and Figure 2As shown, the large-sized wheel hub 10 can be positioned via the first positioning surface 113 of the upper positioning groove 111, while the small-sized wheel hub 10 can be positioned via the second positioning surface 114 of the boss 112. Specifically, when the boss 112 passes through the cavity 103 of the large-sized wheel hub 10, it combines with... Figure 5 As shown, at this time, most of the area of ​​the first positioning surface 113 can fit with the outer ring 102 of the rim of the hub 10, while at this time, part of the second positioning surface 114 of the boss 11 is separated from the inner ring 104 of the rim of the hub 10, and another part fits with the inner ring 104 of the rim of the hub 10, so that the hub 10 of this size can be clamped by the first positioning surface 113 and the second positioning surface 114 and positioned in the upper positioning groove 111.

[0027] Similarly, when the boss 112 passes through the cavity 103 of the small-sized hub 10, it engages... Figure 5 As shown, at this time, most of the area of ​​the second positioning surface 114 can fit with the inner ring 104 of the wheel hub 10, while at this time, part of the first positioning surface 113 of the upper positioning groove 111 is separated from the outer ring 102 of the wheel hub 10, and another part is fitted with the outer ring 102 of the wheel hub 10, so that the wheel hub 10 of this size can also be clamped by the first positioning surface 113 and the second positioning surface 114 and positioned in the upper positioning groove 111.

[0028] As can be seen from the above, since at least part of the first positioning surface 113 of the upper positioning groove 111 can fit with the outer rim 102 of the wheel hub 10, and at least part of the second positioning surface 114 of the boss 112 can fit with the inner rim 104 of the wheel hub 10, the positioning requirements of two different sizes of wheel hubs 10 on the partition plate 1 can be met by the fitting of the first positioning surface 113 and the second positioning surface 114 with the outer rim 102 and the inner rim 104 of the wheel hub 10, respectively.

[0029] Furthermore, it is worth noting that in some embodiments, the first positioning surface 113 can be a continuous circular surface. Or, in other embodiments, such as Figure 1 and Figure 2 As shown, the first positioning surface 113 includes a plurality of concave first arc surfaces 1131 formed by breaking the axis around the positioning groove 111. Furthermore, when the first positioning surface 113 includes a plurality of concave first arc surfaces 1131 formed by breaking the axis around the positioning groove 111, as... Figure 1 and Figure 2As shown, each first arc surface 1131 is arranged around the axis of the positioning groove 111. For example, each first arc surface 1131 can be arranged equidistantly around the axis of the positioning groove 111. Therefore, when each first arc surface 1131 is in contact with the outer ring 102 of the rim of the hub 10, the force on the hub 10 can be evenly distributed on the outer ring 102 of the rim of the hub 10, thereby further improving the positioning effect of the first positioning surface 113 on the hub 10.

[0030] Furthermore, since the upper positioning groove 111 and the boss 112 are eccentrically arranged, the vertical distance between at least one first arc surface 1131 and the second positioning surface 114 is smaller than the vertical distance between the other first arc surfaces 1131 and the second positioning surfaces 114. Therefore, when the boss 112 enters the cavity 103 of the hub 10, the combination... Figure 5 As shown, at least one first arc surface 1131 of the upper positioning groove 111 can also cooperate with the second positioning surface 114 of the boss 112 to clamp the wheel hub 10, thereby effectively preventing the wheel hub 10 from shifting within the upper positioning groove 111 and ensuring the uniqueness of the wheel hub 10's position within the upper positioning groove 111. For example, when the boss 112 enters the cavity 103 of a large-sized wheel hub 10, multiple first arc surfaces 1131 of the upper positioning groove 111 can fit against the outer rim 102 of the wheel hub 10, while the second positioning surface 114 of the boss 112 can partially fit against the inner rim 104 of the wheel hub 10. This allows the large-sized wheel hub 10 to be positioned within the upper positioning groove 111, ensuring the uniqueness of the wheel hub 10's position within the upper positioning groove 111 and preventing the wheel hub 10 of this size from shifting after positioning. Similarly, when the boss 112 enters the cavity 103 of the small-sized hub 10, as... Figure 5 As shown, the hub 10 can be offset toward at least one of the first arc surfaces 1131, so that the hub 10 can be clamped by the second positioning surface 114 of the boss 112 and at least one first arc surface 1131, thereby ensuring the uniqueness of the position of the small-sized hub 10 in the upper positioning groove 111 and avoiding the phenomenon of displacement of the hub 10 of this size after positioning.

[0031] Additionally, it is worth mentioning that in some embodiments, such as Figure 1 and Figure 2 As shown, the second positioning surface 114 is a circular surface, such that when positioning the wheel hub 10, the second positioning surface 114 can at least partially engage with the inner rim ring 104 of the wheel hub 10. However, as an alternative, in some other embodiments, such as... Figure 1 and Figure 2As shown, the boss 112 has a portion protruding in the direction of the first positioning surface 113 along its circumference to form a plurality of protrusions 115, and each protrusion 115 together constitutes the second positioning surface 114 on one side of the first positioning surface 113.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, each protrusion 115 has a second arc surface 1141 on one side relative to the first positioning surface 113, and the vertical distance between at least one second arc surface 1141 and the first positioning surface 113 is smaller than the vertical distance between the other second arc surfaces 1141 and the first positioning surface 113. Therefore, when the protrusion 115 enters the cavity 103 of the wheel hub 10, at least one second arc surface 1141 fits against the inner rim ring 104 of the wheel hub 10. For example, when positioning a large-sized wheel hub 10, combined with... Figure 3 and Figure 5 As shown, after the boss 112 enters the cavity 103 of the hub 10, the outer rim 102 of the hub 10 can be mostly fitted with the first positioning surface 113 of the upper positioning groove 111. Two of the second arc surfaces 1141 of the boss 112 can also fit with the inner rim 104 of the hub 10. The fitting of the two second arc surfaces 1141 with the inner rim 104 of the hub 10 further improves the positioning performance of the hub 10 within the upper positioning groove 111. Furthermore, it should be noted that in some embodiments, the two second arc surfaces 1141 fitting with the inner rim 104 of the hub 10 can be symmetrically arranged, so that the force exerted by the two second arc surfaces 1141 on the inner rim 104 of the hub 10 can be better distributed within the inner rim 104 of the hub 10, thus further improving the positioning effect of the hub 10 within the upper positioning groove 111.

[0033] Furthermore, it is worth noting that in some embodiments, such as Figure 3 and Figure 4 As shown, the boss 112 is formed by pressing the bottom side 13 of the partition 1 towards the top side, thereby forming a lower positioning groove 118 on the bottom side 13 of the partition 1 that can be embedded into the other side of the wheel hub 10. Corresponding to the second positioning surface 114 of the boss 112, the groove wall of the lower positioning groove 118 is a first positioning side 119 that fits against the outer rim 102 of the wheel hub 10. For example, after the small-sized wheel hub 10 is positioned on the upper positioning groove 111 of one of the partitions 1, such as Figure 5As shown, the bottom side 13 of another partition 1 can be placed over the other end face of the hub 10, so that the other end face of the hub 10 can be embedded into the lower positioning groove 118 of the partition 1. The first positioning side 119 of the lower positioning groove 118 and the outer rim 102 of the hub 10 allow the hub 10 to be positioned between the two partitions 1, thus completing the packaging of the hub 10. Similarly, corresponding to the first positioning surface 113 of the upper positioning groove 111, in other embodiments, such as... Figure 4 As shown, the hub positioning structure 11 further includes: a plurality of positioning protrusions 116, each positioning protrusion 116 being disposed on the bottom side 13 of the partition plate 1, and each positioning protrusion 116 being arranged around the axis of the lower positioning groove 118, and each positioning protrusion 116 forming a positioning space that can be embedded into the other end face of the hub 10 around the axis of the lower positioning groove 118. The side of each positioning protrusion 116 facing the axis of the lower positioning groove 118 together constitutes a second positioning side 117 that can be fitted with the outer rim of the hub 10. When the first positioning surface 113 of any partition plate 1 is fitted with the outer rim 102 of the hub 10, the second positioning side 117 of the other partition plate 1 is fitted with the outer rim 102 of the hub 10. Similarly, when the second positioning surface 114 of any partition 1 is in contact with the inner rim 104 of the wheel hub 10, the first positioning side 119 of the other partition 1 is in contact with the outer rim 102 of the wheel hub 10.

[0034] Example 2

[0035] Embodiment 2 of this 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 13 opposite to the top side 12, wherein, as Figure 1 As shown, at least one hub positioning structure 11 as described in Embodiment 1 is provided on the top side 12.

[0036] As can be seen from the above, the wheel hub positioning structure includes a boss 112 and an upper positioning groove 111 surrounding the boss 112. The groove wall of the upper positioning groove 111 is a first positioning surface 113 that can fit with the outer rim of the wheel hub. The side of the boss 112 opposite to the first positioning surface 113 is a second positioning surface 114 that can fit with the inner rim 104 of the wheel hub 10. The first positioning surface 113 and the second positioning surface 114 can respectively meet the packaging requirements of two different sizes of wheel hubs 10. Since the boss 112 and the upper positioning groove 111 are eccentrically set, when the outer rim 102 of one size of wheel hub 10 fits with the first positioning surface 113 of the upper positioning groove 111, the second positioning surface 114 of the boss 112 can also partially fit with the inner rim 104 of that size of wheel hub 10, thereby meeting the positioning requirements of that size of wheel hub 10 in the upper positioning groove 111. Similarly, when the inner rim 104 of a wheel hub 10 of another size is in contact with the second positioning surface 114 of the boss 112, the first positioning surface 113 of the upper positioning groove 111 can be partially in contact with the outer rim 102 of the wheel hub 10, thereby satisfying the positioning requirements of the wheel hub of this size in the upper positioning groove. Since the first positioning surface 113 and the second positioning surface 114 can be in contact with the outer rim 102 and the inner rim 104 of the wheel hub 10 respectively when positioning wheel hubs 10 of different sizes, the uniqueness of the position of the wheel hub 10 on the partition 1 is guaranteed, thereby preventing the wheel hub 10 from shifting on the partition 1 and the wheel hub 10 from vibrating and / or shaking during transportation, thus reducing the probability of wear or damage to the wheel hub.

[0037] Those skilled in the art will understand that the above embodiments are specific implementations of the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
