Foam structure for improving sealing of hole of quarter window cover plate of vehicle

The invention is applicable to the technical field of vibration and noise control, and provides a foam structure for improving sealing of a hole in a cover plate of a quarter window of a vehicle, which comprises a foam body provided with a mounting hole; the foam structure comprises a foam body and at least one circle of mounting hole, the at least one circle of hole position convex rib is arranged on the foam body and located on the outer side of the mounting hole, and at least one circle of mounting surface convex rib is arranged on the mounting surface of the foam body. The foam structure for improving the sealing of the vehicle quarter window cover plate hole is provided with the hole position convex rib and the mounting surface convex rib on the basis of a traditional foam structure, and is simple and convenient; the effect is good, the positions near the hole positions are directly sealed through the hole position convex ribs, and airflow circulation can be mostly blocked; extremely few leaked airflow i
