Scissor-Link Folding Cart Layout for Lower Folded Volume

The folding assembly is nested within the space between the first and second frame assemblies when folded, with the bottom support assembly also folded within the same space. This nesting arrangement allows the moving parts to be contained within the bounding box of the frame assemblies, minimizing the overall volume when the cart is in its compact state.

The bottom support assembly is designed to fold in a direction perpendicular to the folding direction of the folding assembly. This multi-dimensional folding approach allows both components to be compacted simultaneously without interfering with each other, achieving a more space-efficient folded configuration.

The cart is divided into distinct modular components: frame assemblies, folding assemblies, and bottom support assemblies. Each module can be independently manufactured and assembled, which simplifies the overall manufacturing process despite the complex folded configuration. The segmentation allows for standardized production of individual components.

The folding assembly utilizes a dynamic scissor linkage mechanism with slide sleeves that allow for smooth expansion and contraction. This dynamic design achieves compact folding without requiring complex locking mechanisms or multiple discrete parts, as the sliding action naturally provides the necessary constraints and movement.
