The invention discloses a ceiling capable of preventing splash during side curtain blasting and a manufacturing method thereof, and relates to the field of vehicle ceiling structures, the ceiling comprises a ceiling body, the ceiling body comprises a facing layer and a base material layer, a lower shell is arranged on the side, away from the facing layer, of the base material layer, and an upper shell used for being connected with an automobile metal plate is fixedly arranged on the lower shell; a weakening part is arranged between the upper shell and the lower shell and used for reducing the connecting strength between the upper shell and the lower shell, and when external force pushing the upper shell and the lower shell to be separated is generated between the upper shell and the lower shell and exceeds the bearing range of the weakening part, the upper shell and the lower shell are separated with the weakening part as the center. A buffering connecting piece is arranged between the lower shell and the upper shell, and when the upper shell and the lower shell are separated from each other, the buffering connecting piece is used for buffering the upper shell and the lower shell and limiting the distance between the upper shell and the lower shell after separation. The ceiling mounting structure has the advantages that the ceiling mounting stability is improved, and meanwhile the side air curtain can be conveniently disengaged.
本发明公开了一种侧帘爆破时防飞溅物的顶棚及其制造方法,涉及车辆顶棚结构领域,其包括顶棚本体,顶棚本体包括面饰层和基材层,基材层背离面饰层的一侧设有下壳体,下壳体固设有用于连接汽车钣金的上壳体,且上壳体与下壳体之间设有弱化部,弱化部用于降低上壳体与下壳体之间的连接强度,当上壳体与下壳体之间产生推动上壳体与下壳体分离的外力,且外力大小超过弱化部承受范围时,上壳体与下壳体以弱化部为中心分离,下壳体与上壳体之间设有缓冲连接件,当上壳体与下壳体相互分离时,缓冲连接件用于对上壳体与下壳体进行缓冲,并且限制上壳体与下壳体在分离后的距离。本申请具有在提高顶棚安装稳定性的同时,便于侧气帘脱出的效果。
