[0002] The door panel is part of the interior of the car, usually located on the inside of the door, used to cover and decorate the internal structure of the door. The door panel provides protection for the mechanical and electronic components inside the door, such as the electric window mechanism, door locks, etc. It also helps to reduce noise and vibration, and improve the comfort and quietness of the car. When the vehicle is driving, it will generate a variety of noises from the engine, wind, road friction, etc. The sound insulation pad can make the car quieter by absorbing and blocking these noises and reducing the extent to which they are transmitted into the car. This not only improves the acoustic environment in the car, but also helps the comfort of passengers and drivers when communicating or enjoying music in the car.
[0003] However, most car door panels do not have a structure for quickly replacing the internal sound insulation material during use. They are usually bonded with expanding glue, which results in the previous sound insulation material being unable to be cleaned cleanly due to residual colloid during replacement, requiring technicians to manually clean it, which may cause scratches on the door panel.

[0025] Specifically, by pressing the pressing block 9 to slide on the upper surface of the first slide rail 8, the pressing block 9 drives the L-shaped plate 12 to slide under the limit of the first rotating shaft 13 and the clamping claw 14 to slide under the limit of the second slide rail 15. The clamping claw 14 can quickly fix the inner door panel 1. The clamping claw 14 allows the inner door panel 1 to be fixed without the use of filling glue.
