Battery Box Integration in Commercial Vehicle Floor Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicles face challenges in safely and efficiently installing and maintaining large batteries, which are essential for powering electrical consumers, including refrigeration machines, due to limited space and the need for secure protection from damage.
Innovation Solution
The integration of a battery box between structural elements that extend downward from the floor structure, providing protection and easy assembly/disassembly, along with a support structure that can be adjusted for secure footing, allows for the installation of large batteries and simplifies maintenance, eliminating the need for direct connections to the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If large batteries are installed to power electrical consumers, then the power supply capacity is improved, but the space requirement and protection difficulty increase
Solution Approach 1:
The battery box is installed in the vertical space between the floor structure and the downwardly extending components (side walls and support structure), utilizing the third dimension (height/vertical clearance) rather than consuming lateral space. This allows large batteries to be accommodated without increasing the vehicle's overall width or length.
Solution Approach 2:
The battery box is nested within the space created by the vehicle's structural components. The downwardly extending side walls and support structure form a protective enclosure that houses the battery box, effectively nesting the battery system within the existing structural framework of the vehicle.
2Reliability
If batteries are protected from damage, then the reliability is improved, but the assembly and maintenance complexity increases
Solution Approach 1:
The battery system is segmented into a removable battery box that can be easily detached from the vehicle structure. This segmentation allows the battery box to be protected during operation while enabling quick removal for maintenance, replacement, or charging without requiring disassembly of the entire vehicle structure.
Solution Approach 2:
The battery box is designed with dynamic characteristics - it can be in a fixed protected position during operation and easily removed when maintenance is needed. The downwardly extending components provide protection during operation, but the entire battery box can be quickly extracted when required, providing dynamic adaptability between protection and accessibility modes.

AI summary
Described and illustrated is a commercial vehicle (1), in particular a truck, trailer or semi-trailer, with a floor structure (10) supporting a loading floor (9), wherein structural elements (14) are rigidly suspended from the floor structure (10) and are assigned to the two opposite longitudinal sides of the commercial vehicle (1), each extending downwards at least partially. In order to enable the practical, safe and reliable mounting of even relatively large batteries, at least one battery box (17) for receiving at least one electric battery (16) is provided between the structural elements (14) extending downwards at least partially.
