[McJordan]

Solutions for abnormal noise when opening and closing car doors: 1. Check if the door seal is aging and replace it if necessary; 2. Check for any foreign objects in the door gaps and clean them; 3. If the noise is caused by loose parts between door components, tightening the screws can solve the problem; 4. If the noise is due to insufficient body stiffness or welding detachment causing friction between steel plates, it is recommended to seek professional repair at a maintenance shop. The design requirements for car doors are: 1. Ensure ease of passenger entry and exit, with the opening angle controlled between 65 to 70 degrees; 2. Avoid positional interference with other parts during the opening process; 3. Ensure reliable locking when the door is closed to prevent it from opening while driving; 4. Provide good sealing performance; 5. Have a large transparent area to meet lateral visibility requirements; 6. Possess sufficient strength and stiffness to ensure reliable door operation, reduce door vibrations, improve vehicle side collision safety, and prevent door sinking.
