Fan Frame Fixing Mechanism With Elastic Buffer

The patent changes the physical state of the elastic buffer by providing it with a hollow internal cavity filled with buffer material. This structural parameter change allows the buffer to absorb vibrations through the compression and expansion of the buffer material within the hollow space, rather than relying solely on the elastic deformation of a solid washer, thereby maintaining reliability over time

The patent uses a composite structure combining an elastic buffer material with a hollow internal cavity. The buffer material (such as foam, rubber, or gel) is contained within the hollow space of the elastic buffer, creating a composite system that provides both elastic support and vibration absorption, improving durability while maintaining shock absorption capability

The elastic buffer acts as an intermediary element between the screw and the fan frame. It provides a larger surface area for force distribution and creates a more stable connection interface, preventing screw loosening while simultaneously absorbing vibrations. The buffer mediates the connection between the rigid screw and the vibrating fan frame, solving both fixation stability and vibration absorption

The patent introduces a dimensional change by using a hollow elastic buffer with internal buffer material instead of a flat two-dimensional washer. This three-dimensional structure provides enhanced mechanical interlocking and force distribution in multiple directions, preventing screw loosening while maintaining vibration absorption capability
