Air Conditioner Outdoor Unit Foot Vibration Isolation Structure

The foot is divided into three distinct segments: a rigid connection part for structural support, and two elastic isolation parts (first and second end parts) for vibration isolation. This segmentation allows each part to perform its specialized function - the connection part provides strength while the elastic parts provide vibration isolation, resolving the contradiction between structural strength and vibration isolation capability.

The foot employs composite material design with different material properties in different regions. The connection part uses rigid materials for structural support, while the end parts use elastic materials for vibration isolation. This composite approach allows the foot to simultaneously achieve both structural strength and vibration isolation capability.

Instead of using a complete wrapping vibration isolation member, the patent extracts only the essential isolation function by placing elastic end parts at the critical vibration transmission points (the ends of the foot). This extraction approach maintains effective vibration isolation while significantly reducing material usage compared to complete wrapping.

The vibration isolation is applied locally at the end parts where vibration transmission to the installation foundation occurs, rather than uniformly across the entire foot structure. This local quality approach concentrates isolation materials where they are most needed, improving cost-effectiveness while maintaining vibration isolation performance.

The patent merges the vibration isolation function directly into the foot structure itself by integrating the elastic end parts as integral components of the foot. This merging eliminates the need for separate complex isolation mechanisms and their associated installation procedures, thereby reducing installation difficulty while maintaining vibration isolation capability.

The foot structure provides its own vibration isolation function through the integrated elastic end parts, eliminating the need for additional separate isolation components. This self-service approach simplifies the overall system and reduces installation complexity, as the vibration isolation capability is inherent to the foot structure itself.
