Battery Hatch Cover With Synchronized Dual Locking for Waterproof Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery compartment designs in electronic devices face issues with waterproof sealing, ease of disassembly, and reliability of locking mechanisms, particularly in compact designs, leading to potential loss and separation of components under impact.
Innovation Solution
A dual-locking mechanism comprising sliding and rotary buckles, driven by a rotary driving unit, ensures synchronized locking and unlocking, with a sealing ring for waterproofing, enhancing reliability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple rotating shaft structure is adopted to connect and fix the battery hatch cover, then the structure requires enough space for the rotating shaft and the battery hatch cover and equipment are not detachable, but the appearance requirement cannot be achieved in compact designs and the waterproof sealing structure cannot be achieved for thin-shell products
Solution Approach 1:
The locking mechanism is divided into multiple independent locking units (first locking unit with sliding buckles, second locking unit with rotary buckle) that work together. Each locking unit provides independent locking action, distributing the locking function across multiple components rather than relying on a single complex rotating shaft structure.
Solution Approach 2:
Instead of using a traditional rotating shaft that protrudes outward, the patent inverts the approach by using sliding buckles that move horizontally within the plane of the cover and a rotary buckle that rotates within a limiting groove. This inverts the conventional locking mechanism design to achieve compact integration without protruding elements.
2Reliability
If multiple locking mechanisms are provided for fixing the battery compartment cover, then the locking reliability is improved, but the plurality of locking mechanisms are required to be opened one by one in the disassembling process and the requirements of quick disassembly cannot be met
Solution Approach 1:
Multiple locking units (sliding buckles and rotary buckle) are merged into a single integrated locking system controlled by one rotating handle. The rotating handle simultaneously drives all locking units to lock or unlock, combining multiple locking actions into a single operational gesture.
Solution Approach 2:
The rotating handle serves as an intermediary component that transmits the user's rotational input to multiple locking units simultaneously. This intermediary mechanism coordinates the action of all locking units, enabling them to lock and unlock together through a single rotating motion.
3Reliability
If adhesive tape is tightly attached to the connecting gap to meet the sealing waterproof effect, then the waterproof sealing is improved, but the locking or locking needs to overcome the friction force with enough force and the quick operation of a user is not facilitated
Solution Approach 1:
The patent extracts the sealing function from the locking mechanism itself by introducing a separate first sealing ring at the periphery of the cover body. This separates the sealing responsibility from the locking buckles, allowing the locking units to operate without needing to overcome adhesive friction.
Solution Approach 2:
The first sealing ring acts as an intermediary sealing element positioned at the periphery, mediating the waterproof sealing function independently from the locking units. This intermediary sealing structure provides waterproofing without creating friction resistance against the locking operation.
4Device complexity
If the battery compartment cover is fixed by the single buckle or the buckle in a single direction, then the structure is simple, but the single buckle is easy to break or deform and separate to open the battery compartment cover when the battery compartment cover is subjected to large impact vibration
Solution Approach 1:
The patent employs asymmetric locking directions for different locking units. The sliding buckles lock in a first direction (horizontal movement), while the rotary buckle locks in a second direction (rotational movement at an angle). This asymmetric multi-directional locking provides redundant security against impact from different directions.
Solution Approach 2:
The locking mechanism incorporates dynamic elements including sliding buckles that can move horizontally and a rotary buckle that can rotate, allowing the locking system to adapt to various stress directions. The limiting groove guides the rotary buckle's rotation path, providing dynamic locking response to different impact forces.
