Battery Box Assembly With Semi-Accommodating Frame Insertion Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery modules face difficulties in efficient installation due to their complex structure, often resulting in low installation efficiency and potential damage during the installation process, as they may collide with the battery box.
Innovation Solution
A battery box design featuring a semi-accommodating space with a smaller height in the entry direction than the battery module, utilizing a U-shaped middle frame structure and snap-fitting mechanism to securely and conveniently place the battery module, reducing the need for additional connecting members and enhancing assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a battery module with complex structure is installed into a battery box, then the battery can accommodate more capacity, but it becomes difficult to enter the battery box accurately during installation
Solution Approach 1:
The patent applies preliminary action by designing a guide structure (guide plate and guide groove) that is pre-configured in the battery box. This guide structure performs the preliminary action of directing and positioning the battery module during insertion, ensuring accurate entry before the main installation action is completed. The guide plate with guiding portion and the corresponding guide groove work together to automatically align the battery module with the battery box opening, eliminating the need for manual positioning adjustments.
2Productivity
If a battery module is forced into the battery box during installation, then installation can be completed, but collision may occur affecting usage performance
Solution Approach 1:
The patent implements beforehand cushioning through the guide structure that gradually directs the battery module into the battery box. The guide plate and guide groove create a controlled insertion path that cushions the entry process, preventing sudden impacts or collisions. This gradual guidance mechanism ensures the battery module enters smoothly without forcing, thereby protecting both the battery module and battery box from damage while maintaining installation efficiency.
3Stability of the object's composition
If additional connecting members are used to secure the battery module, then the battery module can be firmly fixed, but the occupied installation space increases
Solution Approach 1:
The patent applies merging by integrating the fixation function directly into the battery box structure itself. The guide plate and guide groove are formed as integral parts of the battery box, combining the positioning, guiding, and securing functions into a single unified structure. This eliminates the need for separate connecting members such as bolts or clips, thereby firmly fixing the battery module while minimizing the occupied installation space and maximizing energy density.

AI summary
This application relates to a battery box, a battery, and an electric apparatus. A first end plate, a second end plate, and a first middle frame jointly enclose a semi-accommodating space with an opening at one end, and a height of the semi-accommodating space in an entry direction of a battery module entering the space is smaller than a height of the battery module in the direction, that is, the semi-accommodating space is shallower than the battery module. In this way, when the battery module is placed into the semi-accommodating space, it is less likely to fall and cause damage to the battery module. After the battery module is safely placed into the semi-accommodating space, a second middle frame is spliced with the first middle frame to seal the semi-accommodating space, thereby encapsulating the battery module.
