Battery Cover Connector Case Mounting for Compact Charging Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working vehicles with on-board charging power source connectors face challenges such as cumbersome assembly processes, increased man-hours, and spatial occupancy due to the connector's oblique downward orientation, as well as difficult inspection when the battery cover is opened.
Innovation Solution
The on-board charging power source connector is mounted on a hollow case fixed to the battery cover's outer surface, with the connector case fixed by welding to a reinforcing plate, allowing the charging cable to pass through, and the connector is oriented obliquely to reduce spatial occupancy and facilitate easy assembly and inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the on-board charging power source connector case is fixed to the counterweight by fixing screws inside the case, then the connector is securely mounted, but the assembly work becomes cumbersome and the number of man-hours increases
Solution Approach 1:
The connector case is pre-fixed to the battery cover in the factory before delivery to the construction site. This preliminary assembly action eliminates the need for on-site assembly work, reducing man-hours while maintaining secure mounting through the integrated fixing structure
Solution Approach 2:
The connector case and battery cover are merged into a single integrated assembly. The case is fixed to the outer surface of the battery cover, combining two components into one unit that simplifies installation and reduces assembly complexity
2Stability of the object's composition
If the connector case is mounted on the counterweight with internal fixing, then the mounting is stable, but the assembly process requires more time and labor
Solution Approach 1:
The fixing operation is performed in advance at the factory during manufacturing. The connector case is pre-attached to the battery cover with stable fixing screws before the equipment is deployed, eliminating time-consuming on-site assembly while ensuring mounting stability
3Object-affected harmful factors
If the on-board charging power source connector is covered by the battery cover during inspection, then the connector is protected, but the inspection work becomes difficult
Solution Approach 1:
The battery cover is designed to be openable, segmenting the protective enclosure into accessible and closed states. This allows the connector to be protected when closed and easily inspected when opened, resolving the contradiction between protection and accessibility
Solution Approach 2:
The battery cover transitions from a static closed state to a dynamic openable state. This dynamic design allows the cover to provide protection during normal operation while enabling easy access for inspection and maintenance when needed
4Ease of operation
If the connector case occupies space in the height direction and vehicle width direction, then the connector can be properly oriented, but the overall vehicle space efficiency decreases
Solution Approach 1:
The connector is oriented obliquely rather than purely vertically or horizontally, utilizing diagonal space efficiency. The electricity supply port faces obliquely upward toward the rear side, reducing the projected footprint in both height and width directions while maintaining proper connector orientation and functionality
