Technical Field

[0001] The utility model belongs to the technical field of model cars, and in particular relates to a flywheel level and universal joint connection structure of a model car. Background Art

[0002] Model cars made according to proportion, especially model trains, are not only exquisite collectibles, but their appearance is also completely copied from trains of various countries and eras in smaller sizes. They are authentic and historic, and the railways are also scaled down according to the real railways. Model trains will move like real trains, with adjustable speeds for forward and reverse movements, and their lights will light up or change direction according to the direction of the train. Some may also have additional sound effects or smoke effects to make them as lifelike as real trains.

[0003] The flywheel of the existing model car is connected to the universal joint, and the flywheel needs to be installed on the universal joint, which leads to many processes and inconvenient operation. There is also a risk of the universal joint and the flywheel being loose after installation, resulting in unstable quality. Since the flywheel is connected through the universal joint, the flywheel has many connections and is unbalanced, which is difficult to control and causes a loud noise during operation.

[0005] To achieve the above-mentioned purpose, the flywheel level and universal joint connection structure of the model car provided by the embodiment of the utility model includes a frame and a flywheel, the flywheel is arranged in the frame and connected to the frame, the frame is provided with a mounting groove, the flywheel is arranged in the mounting groove and connected to the frame, the flywheel is provided with a dynamic balancing groove, and the flywheel maintains balance through the dynamic balancing groove.

[0006] As an optional solution of the present invention, there are multiple dynamic balancing grooves, which are evenly arranged on the flywheel, and the flywheel maintains balance through the multiple dynamic balancing grooves.

[0007] As an optional solution of the present invention, the dynamic balancing groove is arranged along the edge of the flywheel.

[0008] As an optional solution of the present invention, the flywheel is an integrated flywheel.

[0009] As an optional solution of the present invention, the width of the dynamic balancing groove is 1-20 mm, and the depth is 2-20 mm.

[0010] The above one or more technical solutions in the flywheel level and universal joint connection structure of the model car provided by the embodiment of the utility model have at least one of the following technical effects:

[0011] The flywheel level and universal joint connection structure of the model car provided by the present application includes a frame and a flywheel. A dynamic balancing groove is directly opened on the flywheel, which eliminates the universal joint installation process, reduces the process, makes the operation more convenient, avoids the risk of the flywheel loosening, and has more stable quality. Since the universal joint is omitted, the flywheel is more balanced, easier to control, and reduces the running noise. BRIEF DESCRIPTION OF THE DRAWINGS
