What is the method to retrieve a card that has fallen into the car door?

[JosieFitz]

The methods to retrieve a card that has fallen into the car door are: 1. Use a wire to hook out the card that has fallen under the door; 2. Remove the door panel to retrieve the card. The car door provides access for the driver and passengers, isolates external interference, and to some extent protects the occupants from side impacts. Car doors can be categorized by their opening methods into: 1. Forward-opening doors; 2. Reverse-opening doors; 3. Sliding doors; 4. Upward-swinging doors; 5. Folding doors; 6. One-piece doors; 7. Split doors. The design requirements for car doors include: 1. The maximum opening angle should be controlled between 65 to 70 degrees; 2. During the opening process, there should be no positional interference with other parts.
