具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
实施例一
一方面，如图1至图2所示，本公开实施例提供了一种后翼子板流水槽加强结构，包括后翼子板流水槽1，后翼子板流水槽1与侧围总成2连接，后翼子板流水槽1包括支撑衬体1-3、流水槽支撑板1-1及与流水槽支撑板1-1连接的支撑加强筋板1-2，流水槽支撑板1-1与侧围总成2连接，支撑加强筋板1-2设于流水槽支撑板1-1的下方，且支撑加强筋板1-2与流水槽支撑板1-1之间形成空腔；支撑衬体1-3嵌入空腔内，且支撑衬体 1-3的形状、尺寸与空腔的形状、尺寸相适配。
在本实施例中，为提高后翼子板流水槽1的整体结构强度，通过在支撑加强筋板1-2与流水槽支撑板1-1之间形成的空腔内嵌入支撑衬体1-3，并将支撑衬体1-3的尺寸、形状设为与空腔的尺寸、形状相适配，以使得支撑衬体1-3在空腔内能对流水槽支撑板1-1及支撑加强筋板1-2实现有效的填充与支撑，同时也有效提高了后翼子板流水槽1的整体强度，利于提升车身的扭转刚度及提高车身的抗侧碰撞性能，利于提高车门乘员的人身安全。
进一步地，通过在支撑加强筋板1-2与流水槽支撑板1-1之间形成的空腔内设有支撑衬体1-3，使得空腔不连续，达到空腔阻断，控制空气、车外噪声流通，减少空气流通及噪声的传递，进而利于提高汽车的NVH特性(Noise噪声、Vibration振动、Harshness粗糙度)，利于提高整体的设计及制造质量。
另外，本公开实施例提供的后翼子板流水槽1加强结构，无需对后翼子板流水槽1设置额外的连接结构件，只需将支撑衬体1-3嵌入空腔内即可，装配简便，且整体结构强度的提升效果好，实用性强，利于进行标准化生产及推广。
特别的，支撑衬体1-3可以在完成支撑加强筋板1-2与流水槽支撑板1-1连接后进行组装，也可以在部分完成支撑加强筋板1-2与流水槽支撑板1-1连接后进行组装，具体可根据实际实施条件来选择合理的安装方式。
具体地，支撑衬体1-3包括骨架1-3-2及设于骨架1-3-2周边的发泡层1-3-1，支撑衬体1-3通过发泡层1-3-1分别与流水槽支撑板1-1及支撑加强筋板1-2接触连接，通过将强度相对较低的发泡层1-3-1分别与流水槽支撑板1-1及支撑加强筋板1-2接触，以防止发泡时对流水槽支撑板1-1及支撑加强筋板1-2造成损伤，利于延长整个后翼子板流水槽1的使用寿命。
在本实施例中，支撑衬体1-3选用骨架1-3-2与发泡层1-3-1相结合的方式，在一个实施例中，发泡层1-3-1附着在骨架1-3-2的周边；采用这种骨架1-3-2式的膨胀胶片，因其具有结构的多变性，能满足不同结构形状及不同尺寸的空腔。另外，骨架式膨胀胶片，在空腔内发泡后填充完全， 对空腔的封堵效果较好。
需进一步说明的是，采用由上述骨架1-3-2及发泡层1-3-1构成的支撑衬体1-3，质轻，利于降低后翼子板流水槽1加强结构的整体重量，利于提高装配效率及生产效率。
在一个实施例中，发泡层1-3-1与骨架1-3-2一体成型。为提高生产效率及便于装配，在本实施例中，发泡层1-3-1与骨架1-3-2采用一体成型的方式制成。
在本实施例中，骨架1-3-2采用PA66材料制成；发泡层1-3-1采用EVA发泡材料制成。
骨架1-3-2采用尼龙-66(PA66)材质制成，发泡层1-3-1采用乙烯-醋酸乙烯共聚物(EVA)材料制成；支撑衬体1-3由PA66材料与EVA发泡材料组成形式，强度较高，能确保其在空腔内固定不变形。
需说明的是，骨架1-3-2的材质不局限于上述PA66材料，发泡层1-3-1不局限于上述EVA材料，只需满足能在空腔内固定不变形的要求即可，具体可根据实际实施条件来选择合理的骨架1-3-2材质及发泡层1-3-1材质。

在本实施例中，为保证后翼子板流水槽1的结构强度，支撑加强筋板1-2及流水槽支撑板1-1均优选采用金属材质制成，如钢板或铝合金，具体可根据实际实施条件来选择合理的材质类型。
在一个实施例中，支撑加强筋板1-2与流水槽支撑板1-1的连接方式为焊接或粘接。
在本实施例中，支撑加强筋板1-2与流水槽支撑板1-1通过焊接的方式固定连接，且支撑加强筋板1-2的底部与流水槽支撑板1-1部分重合，以确保支撑加强筋板1-2与流水槽支撑板1-1的连接效果。
需说明的是，支撑加强筋板1-2除了采用上述焊接或粘接的方式与流水槽支撑板1-1连接外，还可采用螺纹连接或铆钉连接或螺钉连接的方式，具体可根据实际实施条件来选择合理的连接方式。
另一方面，本公开实施例还提供了一种汽车，包括所述的后翼子板流 水槽1加强结构。本公开实施例提供的汽车，因设置有上述技术方案中的后翼子板流水槽1加强结构，因而具备上述技术方案中的全部有益效果，为避免重复，不再赘述。
实施例二
本公开实施例提供了一种后翼子板流水槽1加强结构，包括后翼子板流水槽1，后翼子板流水槽1与侧围总成2连接，后翼子板流水槽1包括支撑衬体1-3、流水槽支撑板1-1及与流水槽支撑板1-1连接的支撑加强筋板1-2，流水槽支撑板1-1与侧围总成2连接，支撑加强筋板1-2设于流水槽支撑板1-1的下方，且支撑加强筋板1-2与流水槽支撑板1-1之间形成空腔；支撑衬体1-3嵌入空腔内，且支撑衬体1-3的形状、尺寸与空腔的形状、尺寸相适配。
其中，支撑衬体1-3包括片状膨胀胶，片状膨胀胶的形状、尺寸与空腔的形状、尺寸相适配，具体地，将片状膨胀胶完全填充满空腔，以有效提高后翼子板流水槽的结构强度。
在本实施例中，支撑衬体1-3采用片式膨胀胶支撑，可根据空腔的具体结构及尺寸进行切割，以达到与空腔相符形状，并在烘烤后实现密封阻断效果。采用这种结构形式的支撑衬体1-3，因结构单一，无需复杂成形结构，价格低廉；且这种片式膨胀胶用人工剪切即可完成产品形状，既能满足汽车厂要求，又节省工时及机械切割费用。
其它技术方案与实施例一中的相同，为避免重复，不再赘述。
综上所述，本公开实施例提供了一种后翼子板流水槽加强结构，包括后翼子板流水槽，后翼子板流水槽与侧围总成连接，后翼子板流水槽包括支撑衬体、流水槽支撑板及与流水槽支撑板连接的支撑加强筋板，流水槽支撑板与侧围总成连接，支撑加强筋板设于流水槽支撑板的下方，且支撑加强筋板与流水槽支撑板之间形成空腔；支撑衬体嵌入空腔内，且支撑衬体的形状、尺寸与空腔的形状、尺寸相适配。本公开实施例提供的后翼子板流水槽加强结构，通过在支撑加强筋板与流水槽支撑板之间的空腔内嵌入支撑衬体，以有效提高后翼子板流水槽的整体强度，利于提升车身的扭转刚度及提高车身的抗侧碰撞性能，利于提高车门乘员的人身安全。同时，本公开实施例提供的流水槽加强结构，无需增设新的连接结构，结构简单， 设计合理且装配简便，整体强度加强效果好，实用性强，利于进行标准化生产及推广。
最后应说明的是：以上实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本公开各实施例技术方案的精神和范围。
