Electric Vehicle Rear Structure with Separate Battery and Article Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear structures for electric vehicles limit storage capacity and ease of loading/unloading due to the placement of batteries and lack of efficient access points, with existing designs often restricting the placement and retrieval of batteries and baggage.
Innovation Solution
A rear structure for electric vehicles featuring a battery storage unit below an article storage unit, with separate opening mechanisms and inclined surfaces for easy access, allowing both baggage and battery storage and retrieval through multiple access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery is disposed in the casing at the rear of the vehicle, then the drive source is integrated into the rear structure, but the battery becomes difficult to take in and out
Solution Approach 1:
The rear structure is divided into separate compartments: an article storage unit for general storage and a dedicated battery storage unit for battery placement. This segmentation allows the battery to be easily accessed and removed from its own compartment without affecting other stored items, resolving the contradiction between integrated storage and ease of battery access.
2Quantity of substance
If articles are stored only in the refrigerator, then the refrigeration function is maintained, but the overall storage capacity is limited
Solution Approach 1:
The invention merges multiple storage functions into a single rear structure: the refrigerator for temperature-sensitive items, the article storage unit for general dry storage, and the battery storage unit for power supply. This combination significantly increases overall storage capacity while maintaining organized functionality through separate access points for each compartment.
3Quantity of substance
If the refrigerator greatly projects rearward, then refrigeration capacity is adequate, but the load weight on top of the refrigerator is limited
Solution Approach 1:
The invention utilizes the horizontal dimension by placing the article storage unit and battery storage unit beside the refrigerator rather than stacking them vertically on top. This dimensional rearrangement eliminates the weight limitation on the refrigerator while providing additional storage space in the available lateral space at the rear of the vehicle.

AI summary
In a rear structure for an electric vehicle including, at the rear of the vehicle body, an article storage unit supported on a rear frame, and a first lid configured to cover the article storage unit from above, the electric vehicle includes sub batteries serving as a drive source thereof, the sub batteries are stored in a battery storage unit disposed below the article storage unit, the article storage unit and the battery storage unit include an upper opening and a lower opening, respectively, which are open to the rear side of the vehicle, and a second lid configured to cover the upper opening and the lower opening is formed as a member different from the first lid. Such a rear structure for a vehicle is easy to use, and allows many articles be loaded on the article storage unit and be stored therein.
