Foldable Rear Storage Basket Structure for Low-Speed EVs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-speed electric vehicles face challenges with unstable center of gravity due to roof racks and large, inconvenient rear storage baskets that are difficult to disassemble and organize.
Innovation Solution
A foldable storage basket with a fixing frame, basket body, and opening-closing device, allowing the basket body to be rotated and folded onto the fixing frame, forming a frame structure with an open upper end for easy item placement and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a roof rack is used to place items, then more items can be stored, but the vehicle's center of gravity becomes unstable and the rack is inconvenient to use
Solution Approach 1:
The storage basket is designed to be foldable and movable rather than fixed. The basket can be folded against the vehicle body when not in use and deployed when needed, transforming from a static structure to a dynamic one that adapts to different usage scenarios.
Solution Approach 2:
The storage basket utilizes the vertical space above the vehicle by extending upward from the rear, rather than occupying horizontal space on the roof. This dimensional change allows storage without compromising the vehicle's center of gravity stability.
2Quantity of substance
If a large rear storage basket is used to place more items, then storage capacity increases, but the basket becomes inconvenient to disassemble and organize
Solution Approach 1:
The storage basket is divided into multiple independent components including the basket body, backrest, and side panels that can be easily separated from each other. This segmentation allows for simple assembly and disassembly while maintaining a large storage capacity when assembled.
3Quantity of substance
If a fixed large storage basket is used, then maximum storage capacity is achieved, but space is wasted when fewer items need to be stored
Solution Approach 1:
The storage basket features a foldable design where the basket body and backrest can be collapsed against each other and secured to the vehicle body. This dynamic configuration allows the storage capacity to be adjusted from maximum (unfolded) to compact (folded) based on actual storage needs.

AI summary
A foldable storage basket for a low-speed electric vehicle, including a fixing frame, a basket body, and an opening-closing device. The basket body is rotatably connected to the fixing frame, and the basket body is capable of being folded on the fixing frame and being unfolded relative to the fixing frame through the opening-closing device. The fixing frame is fixed to the low-speed electric vehicle. The basket body includes a basket plate, a fence rotatably connected to the basket plate, and a guardrail rotatably connected to the fence. In condition of the basket body being unfolded relative to fixing frame, the basket body and the fixing frame enclose to form a frame structure with an open upper end.
