The invention relates to the technical field of vehicles, in particular to a partition structure of a vehicle body cavity, the vehicle body cavity is provided with a functional area and a drainage area, the partition structure comprises a partition plate, the partition plate is arranged between the functional area and the drainage area and used for separating the functional area from the drainage area, and the partition plate is provided with a through hole; the one-way valve is arranged in the through hole of the partition plate, and the one-way valve is arranged to be capable of opening the through hole in the direction of the drainage area under the action of preset pressure and resetting to the position where the through hole is closed after the preset pressure disappears. The cavity partition is provided with the one-way valve, the partition effect from the drainage area to the functional area of the vehicle body cavity is achieved, the phenomenon that accumulated water, air flow, noise and the like of the drainage area are transmitted to the functional area is reduced, and meanwhile under the condition that accumulated water exists in the functional area of the vehicle body cavity, the vehicle body cavity cannot be blocked. Accumulated water can be discharged to a drainage area after opening a one-way valve through water pressure, so that the phenomenon that the accumulated water corrodes a metal plate of a vehicle body in a functional area is reduced.

    本申请涉及车辆技术领域,具体涉及一种车身空腔的隔断结构,车身空腔设置有功能区和泄流区,隔断结构包括:隔断板,隔断板设置于功能区与泄流区之间,用于隔开功能区与泄流区,且隔断板设置有贯通孔;单向阀,单向阀设置于隔断板的贯通孔,且单向阀设置为能够在预设压力作用下向泄流区的方向开启贯通孔,并能够在预设压力消失后,复位至关闭贯通孔的位置。本申请提供的空腔隔断设置有单向阀,实现了车身空腔的泄流区向功能区的隔断效果,减少泄流区的积水、气流和噪音等向功能区传递的现象,同时,在车身空腔的功能区存在有积水的情况下,积水还能够通过水压打开单向阀后卸流至泄流区,以此减少功能区存在积水腐蚀车身钣金的现象。
