What Causes Car Doors to Leak Water on Rainy Days?

[OThomas]

Car doors leaking water on rainy days are usually caused by two reasons: water entering while the vehicle is in motion or water seeping in when the vehicle is parked. There are gaps on the car body and doors, making it inevitable for rainwater to penetrate the doors during rainy weather, leading to water leakage. Introduction: Car doors (car-door) provide access for drivers and passengers to enter and exit the vehicle, isolate external interference, mitigate side impacts to a certain extent, and protect occupants. The aesthetics of a car are also related to the design of its doors. 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 impact, the buffer distance is very short, making it easy for passengers inside the car to get injured.
