Bicycle Supporting Frame Segmentation Dynamics

The supporting frame is divided into multiple independent components: a front supporting frame assembly with two first supporting legs, a rear supporting frame assembly with two second supporting legs, connecting bars, and elastic components. This segmentation allows each component to function independently while collectively providing enhanced stability compared to a single metal bar structure.

The supporting frame employs pivotal connections at multiple joints, allowing the frame to dynamically transition between a deployed supporting state and a folded storage state. The elastic components provide automatic return force, enabling the frame to maintain stability when deployed while easily folding when not in use, thus resolving the contradiction between rigidity and flexibility.

The front supporting frame assembly and rear supporting frame assembly are integrated through connecting bars and shared elastic components, forming a unified supporting system. This merging approach distributes the stabilizing function across multiple components while maintaining a coordinated structure that does not excessively increase overall complexity.

The pivotal connections and elastic components create a dynamic system that requires minimal force to initiate folding, as the elastic components naturally assist the folding motion. Once folding begins, the structure collapses smoothly due to the mechanical advantage provided by the pivotal joints, maintaining ease of operation despite strong anti-tipping performance when deployed.
