Forklift Battery Lock Plate Mechanism for Simple Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery forklift lock devices require complicated operations to switch between preventing and allowing battery protrusion, making them cumbersome to use.
Innovation Solution
A battery lock device with a lock plate that moves between two positions, supported by a shaft and locked by a spring-pressed lock pin, allowing for simple operation by sliding the lock pin between holes to change positions, and featuring a sensor and alarm for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock device with multiple lock tools and open-close plates is used, then the battery can be securely locked in both standing and lodging positions, but the operation becomes complicated requiring multiple tools
Solution Approach 1:
The patent combines multiple locking functions into a single integrated lock plate mechanism. The lock plate can rotate to different positions and engages with different holes to provide both standing and lodging position locking, eliminating the need for separate open-lock and close-lock tools.
Solution Approach 2:
The lock plate serves multiple functions: it can be positioned to lock the battery in standing position, lock in lodging position, or remain retracted to allow battery removal. A single lock plate with multiple holes provides universal locking capability for different operational states.
2Reliability
If a lock device with multiple components and operations is implemented, then the battery can be securely restrained, but the device complexity increases
Solution Approach 1:
The patent merges the locking mechanism into a single rotatable lock plate with multiple engagement holes, rather than using separate mechanisms for different locking states. This reduces the number of components while maintaining reliable restraint functionality.
Solution Approach 2:
The lock plate is designed to be rotatable rather than fixed, allowing it to dynamically change position to engage different holes. This dynamic design enables multiple locking states and battery removal capability without requiring multiple separate components.

AI summary
A battery lock device for a forklift includes a lock plate capable of moving between a first position and a second position. The lock plate at the first position is configured to keep a battery from being protruded. The lock plate at the second position is configured to enable the battery to be protruded. The battery lock device includes a shaft configured to rotatably support the lock plate with respect to a body, a fixed portion opposed to the lock plate, a lock pin capable of sliding toward the fixed portion in a first direction and away from the fixed portion in a second direction, and a spring configured to press the lock pin in the first direction. First and second holes are provided in the fixed portion. The lock pin is inserted into the first and second holes.
