Battery Guide Rails for Connector Alignment in Electric Mowers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric power equipment with rechargeable batteries face difficulties in aligning the battery connectors properly due to the weight of the battery, leading to potential damage or deformation of the connectors during insertion.
Innovation Solution
The use of guide rails and guide ribs within the battery receiving recess and battery housing ensures effortless alignment of the battery connectors by progressively increasing spacing and opposing surfaces, allowing for accurate and secure connection with minimal friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is placed into the battery receiving chamber without alignment guidance, then the connection process is simple, but the connectors may be damaged or excessively deformed due to misalignment
Solution Approach 1:
The guide rails are pre-installed in the battery receiving chamber and the guide ribs are pre-installed on the battery before insertion. These guiding elements are positioned in advance to automatically align the battery and connectors during the insertion process, eliminating the need for manual alignment while preventing connector damage.
Solution Approach 2:
The guide rails and guide ribs act as intermediary elements between the battery and the battery receiving chamber. These intermediaries facilitate the alignment process by providing a physical path that guides the battery into the correct position, ensuring proper connector alignment without requiring complex adjustment mechanisms.
2Weight of moving object
If the battery weight is significant, then the battery can provide sufficient power, but it becomes difficult to align the connectors properly during insertion
Solution Approach 1:
The guiding structure of guide rails and guide ribs is established before the heavy battery is inserted. This pre-established guidance system allows the user to simply place the battery into the receiving chamber without needing to manually align it, making the insertion process as easy as dropping the battery in, regardless of its weight.
Solution Approach 2:
The guide rails and guide ribs enable the heavy battery to self-align during insertion. The guiding elements automatically guide the battery into the correct position without requiring external alignment assistance, allowing the user to simply place the battery without concern for its weight or alignment difficulty.
3Manufacturing precision
If manual alignment is required for connector connection, then the alignment can be precise, but the process requires significant effort and care due to battery weight
Solution Approach 1:
The guide rails and guide ribs are pre-positioned to provide automatic alignment during battery insertion. This eliminates the need for manual alignment operations, allowing the battery to be quickly placed into the receiving chamber without requiring time-consuming adjustment or careful positioning by the user.
Solution Approach 2:
The guiding structure enables the battery-connector assembly to self-align during insertion. The system automatically achieves precise connector alignment through the mechanical guidance of the rails and ribs, eliminating the need for manual intervention and significantly reducing the time required for the connection process.

AI summary
A battery 20 of electric mower 1 is received in a battery receiving recess 40 of the electric mower. A battery side connector 132 is provided in a front end of the battery, and a mower side connector 44 is provided in a front end of the battery receiving recess, and configured to be electrically connected to the battery side connector when the front end of the battery is pushed against the front end of the battery receiving recess. A section of guide rails provided on the bottom surface of the battery receiving recess are configured to guide guide ribs provided on the lower surface of the battery so as to laterally align the battery with respect to the battery receiving recess as the battery is displaced toward the front end of the battery recess.
