Battery Mounting Structure for Flexible Power Unit Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery mounting structures in electric power units, such as lawn mowers, restrict the layout freedom of components due to limited battery connection directions, necessitating design compromises that limit the arrangement of components like handles and protective frames.
Innovation Solution
A battery mounting structure with a placement member, such as a tray, that allows direct electrical connection between the battery and electrical components via a connection member, eliminating the need for terminals on the placement member, and using an engaging member with a pressing part and elastic member for secure attachment, enabling flexible mounting and reduced abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is connected to the battery mounting part along a rail part in a fixed direction, then the battery can be securely mounted and electrically connected, but the degrees of freedom in layout of constituent components including the battery are limited
Solution Approach 1:
The invention separates the mounting function (battery tray with engaging members) from the electrical connection function (connection terminals and harnesses). This segmentation allows the battery to be mounted securely through mechanical engagement while electrical connections are established independently through flexible harnesses, enabling greater layout freedom without compromising mounting security.
Solution Approach 2:
The invention introduces a flexible connection member (harness) as an intermediary between the battery and electrical components. This intermediary allows electrical connections to be made without rigid structural constraints, enabling the battery to be positioned more freely while maintaining reliable electrical connectivity to various components like motors and controllers.
2Reliability
If the battery mounting part includes terminals for electrical connection, then the battery can be electrically connected to electrical components, but the terminals may be damaged during battery mounting operations
Solution Approach 1:
The invention divides the battery mounting structure into a mechanical mounting portion (battery tray with engaging members) and an electrical connection portion (terminals and harnesses). The mechanical engagement features are designed to secure the battery without contacting the electrical terminals, allowing operators to mount and dismount the battery without risk of terminal damage, while maintaining reliable electrical connectivity through the separate harness connection system.
3Stability of the object's composition
If the battery is firmly fixed to the placement member, then vibrations-induced movement is minimized, but the mounting structure becomes more complex
Solution Approach 1:
The invention combines multiple functions into the battery tray structure: mechanical support, positioning guidance, and securing engagement. The engaging members are integrated directly into the tray, and guide rails are formed as part of the tray structure, eliminating the need for separate complex mounting mechanisms while achieving firm fixation that minimizes vibration-induced movement.

Implementation Method 1
by causing the elastic member to elastically deform by the load acting on the battery in an engaged state between the battery and engaging member
