LED Display Module Locking Structure to Prevent Missing Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing LED display devices face issues with missing locking when the LED display module is mounted on a box using multiple locks, leading to potential misalignment and instability.
Innovation Solution
An LED display module with a lock mechanism that includes a lock seat, rotatable lock cylinder, locking member, interference member, and elastic linkage member, which ensures proper alignment and secure mounting by switching between locking and unlocking positions, preventing missing locking through an uneven front surface indication and magnetic attraction structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple locks are used to mount the LED display module on the box, then the reliability of mounting is improved, but the device complexity increases and the ease of operation deteriorates
Solution Approach 1:
The patent combines multiple locking functions into a single integrated lock mechanism. The lock structure includes a lock body, locking member, and interference member that work together as one unit, replacing the need for multiple separate locks. This merging approach maintains mounting reliability while reducing overall system complexity and improving ease of operation.
Solution Approach 2:
The single lock mechanism performs multiple functions: the locking member provides the primary locking function, while the interference member provides a secondary indication function by protruding to show when the lock is engaged. This multi-functionality allows one lock to replace multiple locks while maintaining or enhancing reliability.
2Stability of the object's composition
If multiple locks are used to secure the LED display module, then the stability of mounting is improved, but the ease of operation deteriorates due to the large number of locks
Solution Approach 1:
Multiple locking operations are merged into a single rotational operation of the lock body. The locking member and interference member are both actuated by the same rotational motion, allowing the operator to secure the display module with one simple action rather than managing multiple separate locks.
Solution Approach 2:
The interference member automatically protrudes to indicate when the lock is engaged, providing visual feedback without requiring additional操作步骤. The mechanism self-indicates its state through the interference member's position, making it easy for the operator to confirm proper locking without extra steps.
3Ease of operation
If a single lock mechanism is used, then the ease of operation is improved, but the reliability of preventing missing locking deteriorates
Solution Approach 1:
The interference member serves as a feedback mechanism that protrudes when the lock is engaged and retracts when disengaged. This provides clear visual feedback to the operator about the locking state, preventing missing locking by making the engaged state immediately apparent without requiring additional checks or complex mechanisms.
Solution Approach 2:
While not explicitly using color changes, the invention uses positional changes of the interference member (protruding vs. retracted) as a visual indicator system, similar in principle to color-coded status indicators. The interference member's position provides immediate visual feedback about the locking state.
4Difficulty of detecting and measuring
If the interference member is added to indicate locking status, then the reliability of detecting locking state is improved, but the device complexity increases
Solution Approach 1:
The interference member is integrated into the existing lock structure as an additional function rather than a separate indicator system. It uses the same rotational motion and spatial arrangement as the locking member, providing state indication without requiring a separate detection mechanism or additional complexity beyond the basic lock components.

Function Achieved in This Case
The solution effectively prevents missing locking by ensuring the LED display module is securely mounted on the box, maintaining stability and preventing falls due to magnetic demagnetization or other factors, while allowing easy removal and reinstallation.
Implementation Method 1
an elastic linkage member arranged between the locking member and the interference member. When the locking member is in the unlocking position, the interference member is driven to the interference position by the elastic linkage member, and when the locking member rotates from the unlocking position to the locking position, the interference member rotates from the interference position to the avoidance position
Implementation Method 2
preventing falls due to magnetic demagnetization or other factors

AI summary
The present disclosure provides an LED display module and an LED display device. The LED display module includes a display module body and a lock. The lock includes: a lock seat arranged on a rear side of the display module body; a lock cylinder rotatably arranged in the lock seat; a locking member; an interference member rotatably sleeved on the lock cylinder and spaced apart from the locking member along the axial direction of the lock cylinder, the interference member having an interference position where the interference member locates on a front side of a connecting beam for lifting up the display module body and an avoidance position where the interference member avoids the connecting beam; and an elastic linkage member arranged between the locking member and the interference member. When the locking member is in an unlocking position, the interference member is driven to an interference position by the elastic linkage member. When the locking member rotates from the unlocking position to a locking position, the interference member rotates from the interference position to the avoidance position.
