Anti-impact LED Display Screen Corner Armor Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED display screens are prone to damage during transportation and operation due to unprotected corners, where lamp beads can be knocked off, and existing protection methods fail to adequately safeguard the edges and corners.
Innovation Solution
An anti-impact LED display screen design featuring a protective mechanism with a movable base, corner armor, first and second resilient assemblies, and a limit member, which deploys to cover the module corners when activated, using resilient members to absorb impacts and prevent lamp bead dislodgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the module edge is flush with or beyond the box body edge for seamless splicing, then the splicing effect is improved, but the lamp beads on the module edge become unprotected and prone to damage
Solution Approach 1:
The corner armor is pre-installed on the box body at the module edges, positioned to protrude outward before any impact occurs. This preliminary protective measure ensures that when the module is installed flush with or beyond the box body edge for seamless splicing, the lamp beads are already protected by the protruding corner armor, resolving the contradiction between splicing effect and lamp bead protection.
2Reliability
If foam is used to directly protect the LED display screen during transportation, then the surface protection is improved, but the friction between foam and corners increases the probability of lamp bead dropping
Solution Approach 1:
The corner armor protrudes outward from the box body before transportation, creating a protective barrier that prevents direct contact between the foam and the module corners. This preliminary protective structure eliminates the friction problem while maintaining surface protection during transportation.
Solution Approach 2:
The corner armor acts as an intermediary protective element between the foam and the module corners. Instead of allowing the foam to directly contact and friction against the vulnerable lamp beads at the corners, the corner armor intercepts the contact, transferring the mechanical stress to itself while protecting the lamp beads from friction-induced damage.
3Reliability
If the corner armor protrudes outward to protect module corners, then the impact protection is improved, but the splicing between adjacent displays may be hindered
Solution Approach 1:
The corner armor is designed to protrude only at the specific corner locations of the box body, providing localized protection exactly where the module corners are most vulnerable. This localized protrusion allows the majority of the module surface to remain flush with the box body edge, maintaining seamless splicing between adjacent displays while protecting the critical corner areas from impact.

AI summary
Provided is an anti-impact LED display screen, comprising a box body(1), a module(2), a protective mechanism(3), a first resilient assembly(4), a second resilient assembly(5) and a limit member(6). The protective mechanism(3) comprises a movable base(31) and a corner armor(32). The corner of box body(1) is provided with a groove(11) for accommodating protective mechanism(3), the first resilient assembly(4) is arranged between corner armor(32) and movable base(31); The second residual assembly(5) is arranged between the side wall of groove(11) and protective mechanism(3); When protective mechanism(3) is turned on, the second resilient assembly(5) pushes protective mechanism(3) to move outward of groove(11), and the first resilient assembly(4) pushes the corner armor(32) out of groove(11); when the protective mechanism(3) is reset, the upper end of corner armor(32) abuts against the upper wall of groove(11), limit member(6) limits protective mechanism(3) within groove(11). According to the anti-impact LED display screen provided by the application, when the protective mechanism(3) is turned on, the corner armor(32) can protect the module(2); when the protective mechanism(3) is reset, protective mechanism(3) does not affect the splicing of LED display screens, and has simple structure and convenient operation.
