The invention relates to the technical field of folding sheds and particularly relates to a sound insulation type folding shed assembly. The sound insulation type folding shed assembly comprises a folding shed unit, a pedal piece and a connecting frame piece, wherein the folding shed unit comprises an outer folding shed, an inner folding shed and a plurality of sound insulation pipes, the outer folding shed is arranged on the outer side of the inner folding shed in a sleeving mode and matched with the inner folding shed, the inner folding shed is matched with the pedal piece, and the sound insulation pipes are all arranged between the outer folding shed and the inner folding shed; the multiple sound insulation pipes are in threaded connection with the outer folding shed, the outer folding shed is matched with the inner folding shed, primary noise reduction is achieved by forming an isolation space, then the sound insulation pipes are matched, the noise entering the folding shed assembly is further reduced, and then the noise in a compartment in the running process is effectively reduced; and the use experience of the folding shed assembly is improved.
本发明涉及折棚技术领域,具体涉及一种隔音型折棚总成;隔音型折棚总成包括折棚单元、踏板件和连接架件,折棚单元包括外折棚、内折棚和若干隔音管,外折棚套设于内折棚的外侧,且与内折棚配合,内折棚则与踏板件配合,若干隔音管则均设置于外折棚与内折棚之间,且若干隔音管均与外折棚螺纹连接,利用外折棚与内折棚配合,通过形成隔离空间而实现对噪音的初步降噪,再配合隔音管,从而实现对进入折棚总成中的噪音进一步降噪,进而实现对行驶过程中车厢内部噪音的有效降低,提升折棚总成的使用体验。
