What Causes Water Leakage into Car Doors on Rainy Days?

[DiRemington]

Water leakage into car doors on rainy days is usually caused by two reasons: one is water entering while the vehicle is in motion, and the other is water entering while the vehicle is parked. There are gaps on the car body and doors, so it is inevitable for rainwater to seep into the doors during rainy days, leading to water leakage. Relevant information about car doors is as follows: 1. Introduction: A car door provides access for drivers and passengers to enter and exit the vehicle, isolates external interference, reduces side impacts to a certain extent, and protects occupants. The aesthetics of a car are also related to the design of its doors. 2. Standards for Good Car Doors: The quality of car doors is mainly reflected in their anti-collision performance, sealing performance, ease of opening and closing, and of course, other functional indicators. Anti-collision performance is particularly important because during a side collision, the buffer distance is very short, making it easy to injure occupants inside the vehicle.
