Wall-Mounted Charger Regulating Member for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wall-hanging charger structure is unstable due to positional deviations caused by careless contact, leading to potential disengagement of the protrusion from the tumbler-shaped hole, compromising the charger's hanging state.
Innovation Solution
A charger design with a regulating member that engages with the wall surface in a concave-convex manner, allowing the battery pack to slide and detach without positional deviation, featuring a two-piece housing structure with recessed portions and fixing holes for secure wall mounting, and strap attachment holes for enhanced stability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a tumbler-shaped hole with protrusion is used for wall-hanging mounting, then the charger can be mounted on the wall, but positional deviation occurs when contacted carelessly, leading to unstable wall-hanging state
Solution Approach 1:
The mounting structure is segmented into multiple independent elements: a recessed portion for wall reception, a protrusion for engagement, and a regulating member with regulating portion. This segmentation allows each element to perform its specific function - the recessed portion provides mounting location, the protrusion provides engagement mechanism, and the regulating member prevents positional deviation, collectively achieving stable wall-hanging
Solution Approach 2:
The regulating member acts as an intermediary element between the charger body and the wall surface. Its regulating portion protrudes from the recessed portion and engages with the wall, mediating the interaction between the charger and wall to prevent positional deviation while maintaining the simplicity of the overall mounting structure
2Reliability
If the charger is mounted on the wall, then the charger can be charged, but the battery pack cannot be easily detached without pressing the charger
Solution Approach 1:
The regulating member is positioned locally at a specific location within the recessed portion, not throughout the entire charger body. This localized regulation allows the charger to remain stable on the wall while permitting easy battery pack detachment through upward sliding, as the regulating member only constrains horizontal positional deviation rather than vertical movement

AI summary
A charger for charging a battery pack used as a power source in an electric tool is provided, and particularly, in a multi-port type charger in which a plurality of battery packs can be charged at one time, wherein the function for installing the charger in a wall-hanging state or for shouldering and carrying the charger is not considered. An object of the present invention is to provide the function without damaging durability and compactness of the charger. A pair of right and left fixing holes (30 and 30) and a pair of strap attachment holes (31 and 31) are provided on a rear surface of a main body housing (20) at a position which does not protrude from a side area S in a planar view. A bottom edge portion (25a) of an upper recessed portion (25) is provided above the fixing hole (30) to cover each of the right and left fixing holes, the strap attachment holes (31 and 31) are provided to be coaxial with the bottom edge portion (25a), and it is ensured that durability and compactness of the charger are obtained.
