Description

Technical Field

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

[0002] Remote-controlled model cars are highly customizable, allowing users to modify them in every way, from appearance to performance, according to their budget, skills, and preferences. This includes customization of the exterior and body, as well as performance and powertrain. The inventors discovered that in existing technologies, the wheel offset (the deviation between the wheel mounting surface and the wheel rim centerline) of remote-controlled model cars is usually fixed and not adjustable. To change the wheel track, users must either purchase wheels with different offsets or lengthen the hexagonal wheel hubs and axles. Both of these modification options require customization from manufacturers, resulting in high costs in terms of both money and time. Utility Model Content

[0015] The second boss, at least three of the second bosses, are disposed on the second central disk and are spaced apart around the axial direction of the second central disk.

[0016] Preferably, a third mounting hole is provided between at least three of the second bosses. When the connecting seat is fixed with the third mounting hole, the mounting surface and the center line of the hub form a third offset in the axial direction. A fourth mounting hole is provided on each of the second bosses. When the connecting seat is fixed with the fourth mounting hole, the mounting surface and the center line of the hub form a fourth offset in the axial direction.

[0017] Preferably, the first boss and the second boss are offset from each other around the same axial direction.

[0018] Preferably, the size of the first offset is -3mm to -1mm, the size of the second offset is -0.5mm to 1mm, the size of the third offset is 4mm to 6mm, and the size of the fourth offset is 6.5mm to 8mm.

[0019] Preferably, the coupling seat includes a mounting plate and a coupling portion, the coupling portion extending radially outward from the edge of the mounting plate for detachable connection with the inner ring of the wheel hub or the outer ring of the wheel hub.

[0020] Preferably, the mounting plate has a central hole and a mounting cylindrical wall surrounding the central hole, the mounting cylindrical wall being formed with an internal hexagonal structure, and the mounting surface being located on the inner bottom surface of the mounting cylindrical wall.

[0021] Preferably, the outer ring of the wheel hub has a first center opening, and the inner ring of the wheel hub has a second center opening. When the connecting seat is fixed to the outer ring of the wheel hub, the mounting cylinder wall is located inside the first center opening and the second center opening; when the connecting seat is fixed to the inner ring of the wheel hub, the mounting cylinder wall is away from the first center opening and the second center opening.

[0022] The above-described solution of this utility model has at least the following beneficial effects:

[0023] The model wheel hub provided by this utility model can have its mounting seat installed on the outer ring of the hub, so that the mounting surface of the mounting seat can form a first offset or a second offset with the center line of the hub.

[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 below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0041] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "circumferential", "radial", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] The model wheel hub of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 3As shown, the model wheel hub provided in this embodiment of the present invention includes: an outer ring 10, an inner ring 20, and a connecting seat 30. The inner ring 20 is coaxially fixed with the outer ring 10 and has a hub centerline CL10 formed together in the radial direction. The hub centerline CL10 represents the centerline passing through the side section of the wheel rim and is used to equally divide the wheel rim structure. The connecting seat 30 has a mounting surface 301, which is used to support the tire and maintain its radial direction. The mounting surface 301 can be connected to the drive shaft through bolt holes. The connecting seat 30 is configured to be coaxially fixed with the inner ring 20 or the outer ring 10.

[0047] Reference Figure 3 As shown, the coupling seat 30 includes a mounting plate 302 and a coupling portion 303. The coupling portion 303 extends radially outward from the edge of the mounting plate 302 for detachable connection with the inner ring 20 or the outer ring 10 of the wheel hub. The coupling portion 303 is provided with a through hole 306. The through hole 306 can be fixed with a first mounting hole 104, a second mounting hole 105, a third mounting hole 204, or a fourth mounting hole 205 by bolts, so that the operation of the coupling seat 30 and the outer ring 10 or the inner ring 20 of the wheel hub is simpler and more convenient when modifying and assembling.

[0048] Furthermore, the mounting plate 302 has a center hole 304, which can be used to connect with the drive shaft of the model car. The mounting cylinder wall 305 surrounding the center hole 304 can fix the drive shaft to the mounting plate 302. The mounting cylinder wall 305 is formed with an internal hexagonal structure, and the mounting surface 301 is located on the inner bottom surface of the mounting cylinder wall 305, so that the drive shaft of the model car can pass through the center hole 304 and be embedded in the mounting cylinder wall 305 by a hexagonal nut to fix the drive shaft and the center hole 304. This ensures that the use of tools can be reduced during the modification process, making the modification operation of the model car easier.

[0049] Therefore, the coupling seat 30 can be detachably connected to the outer ring 10 or the inner ring 20 of the wheel hub via the aforementioned coupling portion 303 using bolts. When the coupling seat 30 is fixed to the inner ring 20 of the wheel hub, the mounting surface 301 and the center line CL10 of the wheel hub form a first offset or a second offset in the axial direction. When the coupling seat 30 is fixed to the outer ring 10 of the wheel hub, the mounting surface 301 and the center line CL10 of the wheel hub form a third offset or a fourth offset in the axial direction. The wheel hub offset represents the distance between the mounting surface 301 and the center line CL10 of the wheel hub, and usually includes positive offset, negative offset, and zero offset. Among them, positive offset means that the mounting surface 301 is located outside the center line (i.e., closer to the vehicle side), zero offset means that the mounting surface 301 is completely coincident with the center line, and negative offset means that the mounting surface 301 is located inside the center line (i.e., further away from the vehicle side).

[0050] Reference Figure 1The outer rim 10 of the hub includes: a first rim 101, a first center disc 102 and a first boss 103. The first center disc 102 is coaxially disposed inside the first rim 101 and is perpendicular to the first rim 101. The first center disc 102 extends radially toward the rim axis. The first rim 101, the first center disc 102 and the first boss 103 may be integrally formed. At least three first bosses 103 are disposed on the first center disc 102 and are evenly spaced around the axial direction of the first center disc 102.

[0051] Reference Figure 2 As shown, the inner rim 20 of the wheel hub includes: a second rim 201, a second center disc 202, and a second boss 203. The second center disc 202 is coaxially disposed inside the second rim 201 and extends inward in the radial direction. The second rim 201, the second center disc 202, and the second boss 203 can be integrally formed. The inner rim 20 of the wheel hub and the outer rim 10 of the wheel hub can be integrally formed or assembled by bolts, so that the second rim 201 and the first rim 101 are spliced ​​into a whole, thereby allowing the tire to be installed and supported on the outside.

[0052] Example 1

[0053] Combination Figure 4 and Figure 5 As shown, each first boss 103 is provided with a first mounting hole 104, and at least three first bosses 103 are provided with second mounting holes 105. The height of the first mounting hole 104 is greater than the height of the second mounting hole 105, and the first mounting hole 104 and the second mounting hole 105 are spaced apart around the axial direction of the first center plate 102. The connecting seat 30 is fixed to the first mounting hole 104 by bolts. At this time, the connecting seat 30 is attached to the first boss 103, so that the mounting surface 301 is located away from the model car, and the mounting surface 301 and the wheel hub center line CL10 are defined by the first boss 103 to form a first offset. At this time, the first offset is a negative offset, that is, the size of the first offset is -3mm to -1mm. The size of the first offset is set according to the actual toy model car, for example, it can be -2mm, etc., so that users can modify the wheel track of the model car according to the first offset, making the assembly requirements simpler.

[0054] Example 2

[0055] Combination Figure 6 and Figure 7 As shown, the coupling seat 30 is fixed to the second mounting hole 105 by bolts. At this time, the coupling part 303 is attached to the first center plate 102, so that the mounting surface 301 on the coupling seat 30 and the hub center line CL10 are defined by the first center plate 102 to form a second offset. Figure 4The mounting surface 301 and the hub centerline CL10 coincide with each other. The second offset is -0.5mm to 1mm. Preferably, the second offset is zero offset, that is, the mounting surface 301 and the hub centerline CL10 coincide in the cross-sectional direction. Therefore, the second offset can be 0mm.

[0056] Example 3

[0057] Combination Figure 8 and Figure 9 As shown, at least three second bosses 203 are provided on the second center plate 202 and are spaced apart around the axial direction of the second center plate 202. A third mounting hole 204 is provided between the at least three second bosses 203. The connecting seat 30 is fixed to the third mounting hole 204 by bolts, so that the connecting seat 30 fits against the second center plate 202. At this time, the mounting surface 301 is located on the side closer to the vehicle, so that the mounting surface 301 and the wheel hub center line CL10 are defined by the second center plate 202 to form a third offset. The third offset is a positive offset, and the size of the third offset can be 4mm to 6mm, for example, it can be 5mm.

[0058] Example 4

[0059] Combination Figure 10 and Figure 11 As shown, each second boss 203 is provided with a fourth mounting hole 205. The connecting seat 30 is fixed to the fourth mounting hole 205 by bolts, so that the connecting seat 30 fits against the second boss 203. At this time, the position of the mounting surface 301 relative to the third mounting hole 204 is closer to the vehicle, so that the mounting surface 301 and the wheel hub center line CL10 form a fourth offset in the axial direction. Preferably, the size of the fourth offset is 6.5mm to 8mm, for example, the fourth offset can be 7mm. It can be understood that by fixing the connecting seat 30 to the outer ring 10 of the wheel hub, a first offset can be formed when the connecting seat 30 is installed with the first mounting hole 104, and a second offset can be formed when the connecting seat 30 is installed with the second mounting hole 105. By fixing the connecting seat 30 to the inner ring 20 of the wheel hub, a third offset can be formed when the connecting seat 30 is installed with the third mounting hole 204, and a fourth offset can be formed when the connecting seat 30 is installed with the fourth mounting hole 205.

[0060] It is understandable that through the above embodiments 1 to 4, when users need to modify model cars with different wheelbases, they can assemble the coupling seat 30 with the outer ring 10 or the inner ring 20 of the wheel hub to form different offsets, thereby reducing the cost of use and the time of customization, allowing users to assemble according to their own needs, and making it more playable.

[0061] Optionally, the first boss 103 and the second boss 203 are offset from each other around their respective axial directions. This ensures that when the outer ring 10 of the wheel hub, the inner ring 20 of the wheel hub, and the coupling seat 30 are fixed by bolts, the bolt size can be changed to complete the assembly, making the overall customization cost lower and the modification operation simpler.

[0062] Preferably, the outer ring 10 of the wheel hub has a first center opening 106, and the inner ring 20 of the wheel hub has a second center opening 206. When the connecting seat 30 is fixed to the outer ring 10 of the wheel hub, the mounting cylinder wall 305 is located inside the first center opening 106 and the second center opening 206. At this time, the offset between the mounting surface 301 and the center line CL10 of the wheel hub is a negative offset or a zero offset. When the connecting seat 30 is fixed to the inner ring 20 of the wheel hub, the mounting cylinder wall 305 is away from the first center opening 106 and the second center opening 206. At this time, the offset between the mounting surface 301 and the center line CL10 of the wheel hub is a positive offset. Thus, different wheel track modifications for the model car can be achieved according to different installation positions of the connecting seat 30, and only simple disassembly and installation operations are required, which greatly reduces the modification cost of the model car and makes it more playable.

[0063] The model wheel hub provided by this utility model can have the coupling seat 30 installed on the outer ring 10 of the hub, so that the mounting surface 301 of the coupling seat 30 and the center line CL10 of the hub can form a first offset or a second offset. Alternatively, the coupling seat 30 can be installed on the inner ring 20 of the hub, so that the mounting surface 301 of the coupling seat 30 and the center line CL10 of the hub can form a third offset or a fourth offset. Thus, when users need to change the wheel track of the model car, they only need to assemble the coupling seat 30 according to their own needs, thereby achieving the modification of the model car without customization, reducing the user's cost and time.
