Battery Pack Locking Beam Layout for Easier Harness Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery pack designs obstruct the installation of wiring harnesses due to partitions, leading to lower production efficiency.
Innovation Solution
A battery pack design featuring a detachable locking beam that partitions the accommodating cavity into a module area and an electrical area, allowing the wiring harness to pass through the locking beam and enter the electrical area, facilitating its installation before the beam is attached to the box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a partition is arranged in the battery pack box to divide the accommodating cavity into module area and electrical area, then the battery pack structure is improved and components are properly organized, but the installation of wiring harness and copper busbar is obstructed, resulting in lower production efficiency
Solution Approach 1:
The partition is divided into a first partition section and a second partition section that are detachably connected. The first partition section is fixed to the box, while the second partition section can be detached to allow passage of wiring harness and copper busbar, then reattached to maintain structural organization. This segmentation enables both proper component organization and efficient installation operations.
Solution Approach 2:
The partition is designed with pre-formed openings or gaps in the first partition section, and corresponding passages in the second partition section, allowing wiring harness and copper busbar to be routed through before the second partition section is fully reattached. This preliminary routing action simplifies the installation process while maintaining the final structured organization.
2Strength
If the box and partition are manufactured through welding or as one-piece structure, then structural strength and stability are improved, but the installation operations of wiring harness and copper busbar are obstructed by the partition, resulting in lower production efficiency
Solution Approach 1:
The partition is segmented into detachably connected sections rather than being a single welded or one-piece structure. This allows the second partition section to be temporarily removed or opened during wiring installation, then reattached to restore structural strength. The segmentation enables flexible installation operations while maintaining overall structural integrity.
Solution Approach 2:
The partition transitions from a static welded or one-piece structure to a dynamic structure with detachable connections. The second partition section can be moved between attached and detached states, enabling flexible access for wiring installation while maintaining structural strength when attached. This dynamic capability resolves the conflict between structural integrity and installation efficiency.

AI summary
A battery pack (100) and an electronic device are provided in the present disclosure. The battery pack (100) includes a box (10), having an accommodating cavity; a locking beam (11), detachably connected to the box (10), wherein the accommodating cavity is partitioned into a module area (41) and an electrical area (42) by the locking beam (11); a battery module (20), arranged in the module area (41); a first cover (31), connected to the box (10) and covering the module area (41); wherein a gap is defined between the locking beam (11) and a bottom of the accommodating cavity, and a wiring harness (21) connected to the battery module (20) passes through the locking beam (11) from below and enters the electrical area (42). In this way, the routing and installation of the wiring harness (21) can be facilitated, thereby improving production efficiency of the battery pack (100).
