Movable shutter with sound absorption function
The invention discloses a movable shutter with a sound absorption function. The movable shutter comprises a fixed frame, a plurality of blades hinged into the fixed frame, a movable frame arranged in the fixed frame and blade connecting rods respectively hinged with the blades and the movable frame, and each blade comprises a blade shell and a sound absorption material arranged in the blade shell. The movable shutter has the beneficial effects that the sound absorption materials are arranged in the blades, so that the blades have a sound absorption function, noise transmitted from the interior of a locomotive to the outside can be reduced, and noise pollution to the environment outside the locomotive is reduced.
本发明公开了一种带吸音功能的活动百叶窗，包括固定框架、若干个铰接在固定框架内的叶片、设置在固定框架内的活动框架和分别与叶片与活动框架铰接的叶片连杆，所述的叶片包括叶片外壳和设置在叶片外壳内的吸音材料。本发明的有益效果是：本方案通过在叶片内设置吸音材料，使得叶片具备吸音的功能，从而能够减少从机车内传递至外界的噪音，减少对车外环境的的噪音污染。
