Air Deflector Driving Device With Limiting Structure

The patent introduces a limiting structure as an intermediary component between the connecting rod and the driving case. This limiting structure includes limiting members with limiting grooves that guide and constrain the connecting rod's movement, preventing lateral displacement while maintaining the simplicity and lightness of the connecting rod itself. The intermediary structure resolves the contradiction by providing stability without requiring the connecting rod to be complex or heavy.

The patent segments the stabilization function from the connecting rod itself and places it in the driving case through separate limiting members. The limiting structure is divided into multiple limiting members (first limiting member, second limiting member, etc.) that work together to constrain movement in different directions. This segmentation allows the connecting rod to remain simple while the stabilization function is distributed across multiple dedicated components.

The patent uses a dynamic limiting structure where limiting members with grooves guide the connecting rod along its trajectory. The limiting grooves are designed to accommodate the required movement path while preventing deviation. This dynamic guidance system provides reliable trajectory control without requiring complex mechanical linkages or multiple constraint mechanisms, thus improving reliability while controlling complexity.

The limiting structure serves multiple functions simultaneously: it guides the connecting rod along the preset trajectory, prevents lateral displacement, supports the connecting rod during movement, and maintains proper alignment. By making the limiting structure multi-functional, the patent achieves reliable operation control without adding separate components for each function, thereby controlling overall device complexity.
