Battery Mounting Structure Integrating Locking Barrel and Removal Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery mounting structures for electric vehicles require additional space for a shaft and auxiliary removal lever, increasing the size and weight of the mounting part.
Innovation Solution
A battery mounting structure that uses a cylindrical locking device with a locking barrel to support the auxiliary removal lever, eliminating the need for a separate shaft and incorporating a biasing member to facilitate easy battery removal and mounting, thereby reducing the size and weight of the mounting part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate shaft is used to support the auxiliary removal lever, then the lever can be properly supported, but the mounting part size increases
Solution Approach 1:
The patent combines the shaft function with the locking barrel by making the locking barrel itself serve as the support for the auxiliary removal lever. The locking barrel has a through-hole that receives the auxiliary removal lever, eliminating the need for a separate shaft component. This merging of functions reduces the number of parts and decreases the mounting part area while maintaining reliable support for the lever.
2Reliability
If a separate shaft is used to support the auxiliary removal lever, then the lever can be properly supported, but the mounting part weight increases
Solution Approach 1:
The patent merges the shaft and locking barrel into a single integrated component. The locking barrel serves dual purposes: providing the locking function and supporting the auxiliary removal lever. This eliminates the separate shaft component and its associated weight, reducing the overall mounting part weight while maintaining the necessary support functionality.
3Area of stationary object
If the auxiliary removal lever is pivotally supported by the locking barrel, then the mounting part size is reduced, but the locking barrel structure becomes more complex
Solution Approach 1:
The patent implements a nested structure where the auxiliary removal lever is received within a through-hole of the locking barrel. The lever is pivotally supported by the locking barrel through this nested arrangement, allowing the lever to move within the space created by the through-hole. This nesting approach minimizes the additional structural complexity while achieving compact integration.
4Ease of operation
If the locking barrel is inserted into a biasing member, then the auxiliary removal lever can be easily biased, but the mounting part structure becomes more complex
Solution Approach 1:
The patent combines the locking barrel and biasing member into an integrated assembly where the locking barrel is inserted into the biasing member. The biasing member provides the necessary elastic biasing force to the auxiliary removal lever through this integrated structure. This merging approach provides easy operation of the lever while minimizing structural complexity compared to having separate, independently mounted components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces the size and weight of the battery mounting part by sharing the locking barrel for support and using a biasing member to pivot the auxiliary removal lever, enhancing the efficiency of battery installation and removal processes.
Implementation Method 1
the locking barrel is inserted into a biasing member that biases the auxiliary removal lever in the other direction

AI summary
A battery mounting structure includes a locking device 23 that fastens and releases a battery 13 mounted on a mounting part 16, and an auxiliary removal lever 24 that presses the battery 13 in a released state from the mounting part 16 in a removal direction. The locking device 23 has a cylindrical locking barrel 27. The auxiliary removal lever 24 has a pushing member 32 that presses the battery 13 in the removal direction and is pivotally supported by the locking barrel 27 so as to be fit onto the locking barrel 27.
