Battery Securing Mechanism With Lifting Column for Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery securing components in straddle-type electric motorcycles require complex and inconvenient operations for battery insertion and removal due to large-angle flipping of compartment covers, which also limit design flexibility and increase interference with vehicle structures.
Innovation Solution
A battery securing component with a lifting column and a pressing sleeve, featuring an elastic engaging structure and pressure receiving grooves, allows for simple rotation and vertical movement to lock and unlock the battery, reducing the need for large-angle movements and enabling easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a compartment cover is flipped at a large angle to fully expose the opening for battery insertion and removal, then the battery can be installed and removed more smoothly, but the operation becomes more troublesome and inconvenient, and it limits the design of the compartment cover and vehicle head to avoid interference with vehicle structures
Solution Approach 1:
Instead of flipping the compartment cover upward at a large angle to expose the battery, this patent inverts the approach by rotating the pressing arm downward around the lifting column to press the battery into the storage compartment. The compartment cover remains stationary or rotates minimally, while the pressing mechanism performs the securing action through a different motion path that avoids structural interference.
Solution Approach 2:
The battery securing mechanism is segmented into distinct functional components: a stationary or minimally moving compartment cover, a lifting column for vertical movement, and a pressing arm for radial pressing action. This segmentation allows each component to perform its specific function with optimized motion, eliminating the need for the entire cover assembly to rotate at a large angle.
2Ease of operation
If a compartment cover is flipped at a large angle to fully expose the opening, then the battery can be installed and removed more smoothly, but placing and removing the battery becomes more troublesome and inconvenient
Solution Approach 1:
The patent inverts the conventional flipping motion by using a downward rotating pressing arm mechanism. The pressing arm rotates around the lifting column to press the battery into place, requiring minimal rotation angle and eliminating the need for large-angle cover flipping, thus reducing the time and effort required for battery installation and removal.
Solution Approach 2:
The lifting column and pressing arm are pre-positioned to align with the battery's insertion path. The pressing arm is already in place to receive and press the battery as it is inserted, eliminating the need for additional movements or adjustments during the installation process, thereby reducing the overall time required.
3Ease of operation
If a compartment cover is flipped at a large angle, then the opening can be fully exposed for battery removal and insertion, but it interferes with structures in the front portion of the vehicle
Solution Approach 1:
Instead of rotating the compartment cover upward and forward at a large angle, the patent inverts the motion by rotating the pressing arm downward around the lifting column. This alternative motion path directs the pressing action away from the vehicle's front structures, eliminating interference while maintaining full access to the battery.
Solution Approach 2:
The patent changes the dimension of motion from vertical flipping of the cover to radial rotation of the pressing arm around the lifting column. This dimensional change allows the battery securing mechanism to operate in a different spatial plane that does not conflict with the vehicle's front structures, maintaining battery accessibility without structural interference.
