Description

Technical Field

[0001] This utility model relates to the field of automobile model technology, and in particular to a sensor-activated automobile model wheel hub fixing mechanism. Background Technology

[0002] In sensor-controlled car models, whether static models for collection and display or remote-controlled models capable of dynamic movement, the connection and fixing mechanism between the wheel hub and axle is a crucial component. The performance of this mechanism directly affects the model's display effect, transmission efficiency, ease of disassembly, and overall reliability. In existing technologies, screws are directly screwed into the threaded holes at the axle end from the front or back of the wheel hub. This structure concentrates stress on a single screw when transmitting torque, easily leading to screw breakage or damage to the wheel hub mounting hole. Existing simple plug-in connections, using a hole in the center of the wheel hub and a protrusion on the axle for insertion, offer convenient disassembly but have low connection strength. They are prone to slippage and detachment when the model is moving at high speed or subjected to lateral forces, resulting in unreliable transmission and inability to guarantee effective power transfer. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a sensor-operated car model wheel hub fixing mechanism. Through various structural improvements, including a matching design between the axle key and the fixing groove, it achieves rapid connection and separation between the wheel hub and the axle. The improved structure of the stabilizing plate and its support ring enhances overall rigidity and prevents axle key misalignment. The improved fit between the external connecting key and the keyway provides a reliable torque transmission path, preventing slippage or loosening. The improved tightening component, combined with a screw structure, allows for wheel hub tightening and loosening simply by rotating a knob, requiring no additional tools. This convenient and quick operation makes it suitable for various scenarios.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0036] See Figures 1 to 10 The inductive car model wheel hub fixing mechanism provided in this embodiment includes: a wheel hub body 1 and an axle connection mechanism 2 and an axle connection plate 3 connected to the wheel hub body 1; the wheel hub body 1 includes: a rim 11 and spokes 16; the spokes 16 are connected to the inner side of the rim 11.

[0037] A spoke support ring 17 is provided at the center of the spoke 16, and an axle body 12 is provided inside the spoke support ring 17;

[0038] The axle body 12 is provided with an axle keyway 14 at its top; an axle key 15 is provided in the axle keyway 14;

[0039] The shaft connection mechanism 2 includes an inner cylinder wall 21 and an outer connection key 22 disposed on the inner side of the inner cylinder wall 21;

[0040] The axle connecting plate 3 is disposed inside the spoke 16. The axle connecting plate 3 is provided with an axle support ring 31, a fixing groove 32 and an axle connecting groove 33, for connecting the wheel hub body 1 and the axle body 12.

[0041] The improved structure of the stabilizing plate and its support ring enhances overall rigidity and prevents axle key misalignment. The improved fit between the external connecting key and keyway provides a reliable torque transmission path, preventing slippage or loosening. The axle key simultaneously connects the spoke support ring and the stabilizing plate support ring, forming a bidirectional fixation that further improves structural stability. This application achieves efficient power transmission and reduces energy loss through the keyway and key combination; its compact structure and clear transmission path make it suitable for the motion requirements of high-precision automotive models.

[0042] See Figures 4 to 6 In this embodiment, the fixing groove 32 is disposed on the outside of the axle support ring 31; the axle connecting groove 33 is disposed on the axle support ring 31; the fixing groove 32 matches the axle keyway 14 and the axle key 15; the fixing groove 32 and the axle keyway 14 are connected by the axle key 15, thus the wheel hub body 1 and the axle body 12 are connected in the rotation direction; when disassembly is required, the wheel hub body 1 is pulled to move outward in the direction of the axle body 12 to complete the quick disassembly.

[0043] See Figures 4 to 8 In this embodiment, an external connecting keyway 23 is provided on the inner side of the inner cylinder wall 21, and the external connecting keyway 23 matches the external connecting key 22; the external connecting key 22 is partially fixed in the external connecting keyway 23, providing a more stable connection;

[0047] The stabilizing plate support ring 41 is located outside the axle support ring 31. The stabilizing plate support ring 41 can prevent the axle key 15 from moving outward.

[0048] See Figures 6 to 7 The axle key 15 is connected to a stabilizing plate support ring 41 on one side and a spoke support ring 17 on the other side. Therefore, the axle key 15 does not need to be fixed separately and will not shift in position, thus improving the stability of the connection. The axle body 12 achieves torque transmission through the engagement of the axle key 15 with the external connecting keyway 23 of the axle connection mechanism 2.

[0049] See Figure 4 , Figure 5 In this embodiment, an elastic frame 5 is provided on the outside of the stabilizing plate 4. The elastic frame 5 includes a support spring 51 and a support barrel 52, which provide elastic preload.

[0050] The support spring 51 of the elastic frame 5 is installed inside the support barrel 52 and acts between the axle connecting plate 3 and the stabilizing plate 4 to provide axial elastic support.

[0051] See Figures 8 to 10 In this embodiment, a screw 13 is connected to the top end of the axle body 12; a tightening component 6 is also connected to the top end of the axle body 12. The tightening component 6 includes a tightening plate 61, a tightening nut 62, a nut hole 63, and a knob 64, which is used to tighten and release the wheel hub by rotation. The nut hole 63 is located on one side of the tightening plate 61; the nut hole 63 matches the thread of the screw 13, and the tightening nut 62 is threadedly connected to the screw 13.

[0052] The tightening component 6 can be installed and disassembled without operation by rotating the tightening nut 62 via the knob 64, which pushes the tightening plate 61 to tighten or release.

[0053] In summary, the above embodiments of this utility model, through various structural improvements and the matching design of the axle key and fixing groove, achieve rapid connection and separation of the wheel hub and axle. The improved clamping component of this application, combined with the screw structure, allows for wheel hub clamping and release simply by rotating the knob, requiring no additional tools and simplifying operation.

The improved cooperation between the external connecting key and keyway provides a reliable torque transmission path, preventing slippage or loosening. The axle key simultaneously connects the spoke support ring and the stabilizing plate support ring, forming a bidirectional fixation, further improving structural stability. This application achieves efficient power transmission and reduces energy loss through the cooperation of the keyway and key.
