Hard Disk Fixing Bracket With Swinging Arms for Fast Assembly

The patent applies the dynamics principle by replacing static screw fastening with a dynamic movable fastener system. The fastener includes swinging arms that can rotate around shafts between locked and unlocked positions, enabling rapid assembly and disassembly while maintaining firm fixation when locked. This dynamic mechanism resolves the contradiction between reliable fixation and assembly efficiency.

The patent segments the fastening function into multiple independent swinging arms that can operate individually or collectively. Each swinging arm acts as an independent fastening element that can be quickly engaged or disengaged, replacing the single complex screw operation with multiple simple segmental actions, thereby improving assembly and disassembly efficiency while maintaining secure fixation.

The patent applies the self-service principle by designing the swinging arm fastener system to be actuated by the hard disk itself during insertion and removal. When the hard disk is inserted, it automatically triggers the swinging arms to rotate into the locked position through the shaft rotation mechanism, eliminating the need for separate fastening operations. This self-service mechanism reduces operational complexity despite the increased structural complexity of the fastener system.

The patent merges multiple functions into the swinging arm mechanism: the same structure provides both the fastening function and the positioning function, while the rotation around shafts combines the locking and unlocking actions into a single motion. This functional merging reduces the number of separate components and operations needed, thereby reducing overall device complexity while maintaining high assembly and disassembly efficiency.

The patent applies parameter changes by selecting buffer pad materials with specific vibration-damping properties and optimizing their thickness and placement locations based on vibration analysis. By adjusting these parameters, the buffer pads provide effective vibration protection without requiring complex structures or additional active components, thereby maintaining ease of manufacture while improving protection against harmful vibrations.

The patent implements beforehand cushioning by pre-installing buffer pads at strategic locations where vibrations are most likely to occur during hard disk operation. These buffer pads are positioned in advance to absorb and dampen vibrations before they can damage the hard disk, providing proactive protection without requiring complex active vibration control systems, thus maintaining manufacturing simplicity.
