AI Technical Summary
Current butterfly door hinges have complex structures, high costs, complex assembly, poor ride comfort, and high failure rates, failing to meet market demands for personalized and fashionable door openings, especially in narrow parking spaces.
A butterfly door hinge design with a hinge connecting arm constraining the door to swing along a fixed point, using a frictional fit between a planar limiting portion and a limiting body to maintain a specific posture, and incorporating a rolling fit between a collision unit and the planar limiting portion to reduce frictional resistance, resulting in a simpler structure, fewer moving pairs, and improved smoothness.
The design simplifies assembly, reduces failure rates, and enhances the smoothness of the opening and closing process while allowing the butterfly door to share a locking system with side-hinged doors, reducing manufacturing costs and improving ride comfort.
