Battery Pack Locking Structure for Ordered Tamper-Resistant Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-professionals often disassemble vehicle battery packs, causing secondary damage and safety risks due to improper maintenance.
Innovation Solution
A tamper-resistant battery pack design featuring interconnected connection structures and an unlocking mechanism that requires a specific disassembly order, making it difficult for non-professionals to disassemble without proper authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery pack is designed with simple assembly structure, then the ease of maintenance is improved, but the risk of unauthorized disassembly increases
Solution Approach 1:
The battery pack is divided into multiple components (cover, bottom plate, service cover) that are interconnected through a sequence of connection structures. Each component must be disassembled in a specific order, creating segmented access control that prevents unauthorized maintenance while allowing professional service when the correct sequence is followed.
Solution Approach 2:
The design incorporates preliminary locking actions through multiple connection structures that must be sequentially unlocked. The first connection structure locks the cover, the second locks the bottom plate, and the third locks the service cover - all requiring preliminary unlocking actions in a specific sequence before any component can be accessed.
2Reliability
If multiple connection structures are added to prevent disassembly, then the tamper resistance is improved, but the device complexity increases
Solution Approach 1:
Multiple connection structures (first, second, and third connection structures) are merged into a single integrated disassembly sequence. The connection structures work together as a unified system where unlocking one structure enables access to the next, combining multiple security functions into a coordinated mechanism that prevents disassembly without the correct sequence.
Solution Approach 2:
The connection structures are designed with dynamic interdependence - each structure's locked state depends on the previous structure being unlocked. This creates a dynamic security system where the accessibility of each component changes based on the disassembly progress, transitioning from all locked to progressively unlocked only when the correct sequence is followed.

AI summary
A tamper-resistant battery pack is provided. The tamper-resistant battery pack includes: a frame beam; a cover; and a bottom plate. A service cover is assembled on the bottom plate. An inner side of the frame beam is provided with a first connection structure configured to prevent disassembly of the cover, a second connection structure configured to prevent disassembly of the bottom plate, and a third connection structure configured to prevent disassembly of the service cover. The third connection structure is provided with an unlocking portion. In case that the unlocking portion is not operated to be unlocked, the service cover is locked by the third connection structure, the cover is locked by the first connection structure, and the bottom plate is locked by the second connection structure.
