Integrated Battery Box Longitudinal Beams for More Cell Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery structure in vehicles has a low utilization rate of installation space due to design flaws, leading to a complex structure that limits the size of the battery and its energy density.
Innovation Solution
A battery box with an integrated structural design that includes longitudinal beams connected to the vehicle body, allowing battery cells to be accommodated between a bearing member and a cover, with the longitudinal beams protruding beyond the bearing member to provide stable support and expand installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the battery structure uses separate supporting structures for the battery box and vehicle body, then the structural strength is sufficient, but the installation space for the battery is reduced and the structure becomes complex
Solution Approach 1:
The patent merges the battery box supporting structure with the vehicle body supporting structure into a single integrated longitudinal beam. The longitudinal beam is designed to simultaneously support both the battery box and connect to the vehicle body, eliminating the need for separate supporting structures. This integration directly increases the installation space for the battery while reducing structural complexity.
Solution Approach 2:
The longitudinal beam is designed as a multi-functional component that serves dual purposes: it acts as both the battery box supporting structure and the vehicle body supporting structure. By making the longitudinal beam universal, the patent eliminates redundant structures and maximizes the space available for battery installation without compromising structural integrity.
2Area of stationary object
If the longitudinal beams are integrated into the battery box structure, then the installation space is expanded, but the connection stability with the vehicle body may be compromised
Solution Approach 1:
The longitudinal beam is segmented into distinct functional zones: a first portion that connects to the vehicle body and a second portion that supports the battery box. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity and connection stability.
Solution Approach 2:
The patent extends the longitudinal beam in the longitudinal direction of the vehicle beyond the lateral boundaries of the battery box. This dimensional extension allows the beam to protrude beyond the battery box in the longitudinal direction, providing stable connection to the vehicle body while maintaining adequate support for the battery box, thus resolving the contradiction between installation space and connection stability.

AI summary
A battery box, a battery, and a vehicle is disclosed. In the design of the battery box, a bearing member is arranged between two adjacent longitudinal beams. With the support of the longitudinal beams, this allows for stable accommodation of battery cells between the bearing member and the cover. The longitudinal beams are connected to the vehicle body and extended along the length direction of the vehicle. In this way, the longitudinal beams of the present application not only serve as the supporting structure of the battery box, but can also directly serve as the supporting structure of the vehicle. By integrating the beam structure of the vehicle into the battery box to form an integrated design, the installation space for the battery in the vehicle is expanded.
