Load Transmission Mechanism for Multi-Directional Training

The patent employs a nested structure where the inner housing containing the main driving shaft and intermediate shaft is positioned inside the outer housing containing the crankshaft and connection joint. This nesting arrangement allows multiple transmission components to be integrated in a compact configuration, achieving enhanced load generation through multiple shafts and joints while controlling overall device complexity through space-efficient design.

The patent introduces an intermediate shaft as a mediator between the main driving shaft and the crankshaft. This intermediate shaft receives rotational input from the main driving shaft and transmits it to the crankshaft, enabling the conversion of rotational motion into multi-directional load application. The connection joint acts as another intermediary that facilitates the transmission of motion and force between different components, achieving enhanced load generation while maintaining manageable device complexity.

The patent employs dynamic elements including rotary shafts that can rotate, an intermediate shaft that transmits rotational motion, and a connection joint that enables multi-directional movement. These dynamic components allow the training machine to adapt to various muscle training needs by facilitating motion in multiple directions (pulling, turning, pushing) while maintaining a relatively compact and manageable device structure through integrated design.

The patent creates a multi-functional system where the combination of the main driving shaft, intermediate shaft, crankshaft, and connection joint enables the same mechanism to perform multiple muscle training functions. The system can apply loads in pulling direction, turning direction, and pushing direction, making it universally applicable for training different muscle groups and movement patterns without requiring separate dedicated mechanisms for each function.
