AI Technical Summary
Technical Problem
Sliding doors cause noise and instability issues during vehicle operation due to impacts, especially impacts and noise caused by the inability to effectively connect with the vehicle body.
Method used
A matching structure between the sliding door and the vehicle body was designed, including an upper guide rail, a lower guide rail, an upper wheel arm, and a lower wheel arm. Through the cooperation of limit pins, positioning buckles, and buffer blocks, the sliding door is ensured to be stable when closed and to buffer and reduce noise when opened.
Benefits of technology
This achieves structural stability and vibration and noise reduction effects for the sliding door during vehicle operation, improving the operational stability of the sliding door and reducing noise generation.
