Description

Technical Field

[0001] This utility model relates to the field of scooter technology, specifically to a desert wheel hub structure. Background Technology

[0002] In existing technologies, the wheels of electric scooters are typically a single-piece structure, mounted on the drive shaft with nuts. However, this one-piece hub structure is prone to deformation or breakage due to localized stress concentration when riding in complex terrains such as deserts and sandy areas. If the rim or tire is damaged, it usually requires complete replacement, resulting in high repair costs and hindering rapid maintenance in outdoor environments. Therefore, a new drive wheel structure is urgently needed to solve these problems. Utility Model Content

[0003] This invention provides a desert wheel hub structure that, through modular design, allows for targeted replacement of damaged parts, significantly reducing spare parts costs and maintenance time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a desert wheel hub structure, comprising: a main body, wherein a through shaft hole is longitudinally provided in the center of the main body, and a radially arranged pin groove is provided at the bottom end of the main body corresponding to the shaft hole; a connecting seat, wherein multiple connecting seats are provided and distributed around the main body, and each connecting seat is provided with a longitudinally through mounting hole; and a positioning protrusion, wherein the positioning protrusion is an annular structure provided on the top of the main body and is coaxially arranged with the shaft hole.

[0005] Preferably, the main body has a first circular groove at the center of its top.

[0006] Preferably, the bottom of the main body is provided with a second circular groove corresponding to each of the mounting holes.

[0007] Preferably, each of the connecting seats has a chamfered corner on its bottom outer edge.

[0008] Preferably, the main body, the connecting seat, and the positioning protrusion are a single metal integral structure.

[0009] Preferably, the depths of the first and second circular grooves are both greater than the heights of the corresponding nuts and bolts.

[0010] Preferably, the inner diameters of the first and second circular grooves are both larger than the outer diameter of the corresponding bolt and nut loading and unloading sleeve tool.

[0011] The beneficial effects of this utility model are as follows: The design of this structure modularly decomposes the stress-bearing and functional components of the traditional one-piece wheel hub. By mounting the wheel hub on the axle head, the wheel hub bears the main torque transmission. The bottom radial pin groove achieves circumferential locking with the axle head by inserting a locating pin. The rim is fixedly connected to each connecting seat by bolts passing through the mounting holes. The locating protrusion ensures the coaxiality of the rim and the wheel hub through the center hole of the rim, avoiding the problem of vibration during operation. In this setting, the concentrated load of the rim is distributed to multiple independent nodes, thus reducing local stress. When the rim or a part of the tire is damaged, only the bolts of the connecting seat need to be removed, so that the rim can be quickly replaced without disassembling and replacing the wheel hub. This not only avoids the impact on the bearings and locating pin components, but also greatly reduces the adjustment time during field maintenance. The first circular groove is used to accommodate the nut at the end of the drive shaft, allowing the nut to sink into the first circular groove, preventing the protruding structure from colliding with obstacles, thus protecting the nut and preventing it from loosening due to external impact. The second circular groove is used to conceal the connecting bolts of the wheel rim, allowing the nuts of the bolts that pass through the mounting holes to sink into the second circular groove, preventing sand and gravel from directly impacting the nuts and causing deformation or detachment when driving on sandy terrain. The inner diameters of the first and second circular grooves also facilitate tool insertion. The unibody metal structure provides enhanced bending and torsional resistance, making it particularly suitable for the unpredictable impact loads in the desert. Furthermore, the one-piece molding ensures the geometric accuracy of the connecting seat and positioning protrusions, reducing the risk of dynamic imbalance during high-speed rotation. In addition, chamfering removes excess material, achieving localized weight reduction without compromising strength. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] according to Figure 1 , Figure 2 , Figure 3 As shown, a desert wheel hub structure includes: a main body 1, wherein the main body 1 has a through shaft hole 2 in the center and a radially arranged pin groove 3 at the bottom end corresponding to the shaft hole 2; a connecting seat 4, wherein multiple connecting seats 4 are arranged and distributed around the main body 1, and each connecting seat 4 has a through mounting hole 5 in the center; and a positioning protrusion 6, wherein the positioning protrusion 6 is an annular structure arranged on the top of the main body 1 and is coaxially arranged with the shaft hole 2.

[0019] The desert wheel hub structure described above is designed to modularly decompose the stress-bearing and functional components of a traditional one-piece wheel hub. By mounting the wheel hub on the axle, the wheel hub bears the main torque transmission. The bottom radial pin groove 3 achieves circumferential locking with the axle by inserting a locating pin. The rim is fixedly connected to each connecting seat 4 by bolts passing through the mounting holes 5. The locating protrusion 6 ensures the coaxiality of the rim and hub through the center hole of the rim, avoiding operational vibration. In this configuration, the concentrated load of the rim is distributed to multiple independent nodes, thus reducing local stress. When the rim or a part of the tire is damaged, only the bolts of the connecting seat 4 need to be removed, allowing for quick replacement of the rim without disassembling and replacing the entire hub. This not only avoids impacting the bearings and locating pin components but also significantly reduces adjustment time during field maintenance.

[0020] The main body 1 has a first circular groove 7 at its top center. The main body 1 has a second circular groove 8 at its bottom corresponding to each of the mounting holes 5. The depth of both the first circular groove 7 and the second circular groove 8 is greater than the height of the corresponding nut or bolt. Furthermore, the inner diameter of both the first circular groove 7 and the second circular groove 8 is greater than the outer diameter of the corresponding bolt or nut mounting / unmounting sleeve tool.

[0021] Through the above design, the first circular groove 7 is used to accommodate the nut at the end of the drive shaft, allowing the nut to sink into the first circular groove 7, preventing the protruding structure from colliding with obstacles, thus protecting the nut and preventing it from loosening due to external impact. The second circular groove 8 is used to hide the connecting bolts of the wheel rim, allowing the nuts of the bolts passing through the mounting hole 5 to sink into the second circular groove 8, preventing sand and gravel from directly impacting the nuts and causing deformation or detachment when driving on sandy terrain. Furthermore, the inner diameter settings of the first circular groove 7 and the second circular groove 8 also facilitate the insertion of tools.

[0022] Each of the connecting seats 4 has a chamfered corner 9 on its bottom outer edge, and the main body 1, the connecting seat 4 and the positioning protrusion 6 are a single metal structure.

[0023] In the above configuration, the main body 1 of the integrated metal structure has stronger bending / torsion resistance, making it especially suitable for unpredictable impact loads in the desert. The integral molding ensures the geometric accuracy of the connecting seat 4 and the positioning protrusion 6, reducing the risk of dynamic imbalance during high-speed rotation. In addition, the chamfer 9 removes excess material, achieving local weight reduction without affecting strength.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
