具体实施方式
参考附图,其中相同的附图标记在几个视图中表示相同的部分,接合结构30包括第一部件32、第二部件34和插入件36。(本文件中的形容词“第一”和“第二”用作标识符而并非旨在表示重要性或顺序)。第一部件32由纤维增强材料形成并且具有限定轴线A的孔38。第二部件34与第一部件32相邻并且具有与第一部件32的孔38对准的孔40。插入件36位于第一部件32的孔38中。插入件36包括具有围绕轴线A的管状形状的内层42、围绕轴线A同心地与内层42相邻的中间层44;以及围绕轴线A同心地与中间层44相邻的外层46。层42、44、46由纤维增强材料形成。内层42与中间层44之间的边界50以及中间层44与外层46之间的边界52中的一个沿平行于轴线A的方向具有非线性轮廓。
插入件36允许由纤维增强材料制成的第一部件32以减少腐蚀风险的方式接合到第二部件34。与第一部件32和第二部件34接合的第二部件34或紧固件48可以由金属形成。当纤维增强材料中的纤维暴露于金属时,纤维会在金属中引起电化学腐蚀、这可能损害接点(例如紧固件48)的强度。插入件36减少了纤维增强材料中的纤维56对由金属制成的部分的暴露,例如减少第一部件32的纤维56对紧固件48和/或第二部件34的金属的暴露。插入件36还可以当第一和第二部件32、34受到反向力时提供额外的能量吸收,从而降低了接合结构30失效(即分离)的风险。
参考图1-4,第一部件32可以具有片状或板状的形状,即长度和宽度远大于厚度。第一部件32的片状形状可以根据第一部件32的需求来弯曲或弯折或成型。作为一个示例,第一部件32可以是如乘客车辆或商用车辆(如小型客车、载重货车、厢式货车、运动型多用途车、旅行车等)的车辆(未示出)的车身面板。具体地,第一部件32可以是车辆的外部车身面板。第一部件32可以具有A级表面(即旨在暴露给顾客并且特别地制造成具有高质量、完美而没有瑕疵的美观的表面)。作为其他示例,第一部件32可以是车辆的结构构件(例如车身加强件、车架构件、立柱、车顶横梁、车顶纵梁、下边梁、车架横梁等)。
第一部件32由纤维增强材料形成;换言之,第一部件32是纤维增强材料。第一部件32的纤维增强材料可以例如是纤维增强塑料或纤维增强聚合物。纤维增强材料包括纤维56。纤维56可以例如由碳、芳族聚酰胺(aramid)、玻璃、聚丙烯腈(polyacrylonitrile)、人造纤维等形成。纤维增强材料包括基体材料,并且纤维56设置在基体材料中。第一部件32的基体材料可以例如是聚酯(polyester)、环氧树脂(epoxy)、聚酰胺(polyamide)、聚碳酸酯(polycarbonate)、聚丙烯(polypropylene)、乙烯基树脂(vinyl)、任何合适类型的聚合物等。
参考图1和图4,第一部件32具有孔38。可以穿过第一部件32的厚度来切出孔38。例如,可以在第一部件32成型之后切出孔38,这导致纤维56的端部暴露在孔38周围。第一部件32的至少一些纤维56可能暴露在孔38中;换言之,至少一些纤维56位于孔38的表面处而没有被例如基体材料覆盖。因此,如果有的话,纤维56可能有在接触纤维56的金属部分中引起腐蚀的风险。
参考图1-4,接合结构30包括第二部件34。第二部件34可以具有片状或板状的形状,即长度和宽度远大于厚度。第一部件32的片状形状可以根据第一部件32的需求弯曲或弯折或成型。例如,第一部件32可以是车辆(未示出)中的车身面板。作为其他示例,第二部件34可以是车辆的结构构件,例如车身加强件、车架构件、立柱、车顶横梁、车顶纵梁、下边梁、车架横梁等等。
第二部件34与第一部件32相邻;换言之,第一部件32与第二部件34之间没有任何东西,并且第二部件34可以接触第一部件32。第二部件34可以与第一部件32齐平。更具体地,围绕第一部件32的孔38的区域58可以接触围绕第二部件34的孔40的区域60。区域58、60可以表示第一部件32和第二部件34的正交于第一部件32的和第二部件34的厚度的宽阔表面。
第二部件34可以由用于其需求的任何适当的坚固和耐用的材料形成;换言之,第二部件34是这样的材料。例如,第二部件34可以由如钢或铝的金属、塑料、如描述第一部件32的纤维增强材料等形成。
参考图1和图4,第二部件34具有与第一部件32的孔38对准的孔40。例如,由第一部件32的孔38限定的轴线A可以与由第二部件34的孔40限定的轴线相同。孔38、40的方向可以是平行的。
参考图2,第一部件32的孔38限定轴线A。该轴线A可以是圆柱坐标系的基线。在圆柱坐标系中,位置P被指定为三个尺寸:平行于轴线A的轴向尺寸z、指向为垂直远离轴线A的径向尺寸r、以及围绕轴线A的周向尺寸θ。轴向尺寸z和径向尺寸r是距离,并且周向尺寸是角度。轴向是平行于轴线A的方向,即轴向尺寸z在径向尺寸r和周向尺寸θ是恒定的时增大或减小。径向是与轴线A正交或远离轴线A的方向,即径向尺寸r在轴向尺寸z和周向尺寸θ是恒定的时增大或减小。周向方向在与轴线A正交的平面内环绕轴线A,即周向尺寸θ在轴向尺寸z和径向尺寸r是恒定的时增大或减小。
参考图4,插入件36位于在第一部件32的孔38中。如图4所示,插入件36可以位于在第二部件34的孔40的外部,或者插入件36可以延伸到第二部件34的孔40中。插入件36可以具有与轴线A对准的圆柱形形状。
参考图4-6,插入件36包括具有围绕轴线A的管状形状的内层42。换言之,内层42可以具有沿着轴线A伸长的圆形,并且可以具有平行于或对准于轴线A延伸穿过内层42的孔62。内层42可以从第一端部64轴向延伸到第二端部66。第二端部66可以接触第二部件34,并且第一端部64可以与第二部件34间隔开并且可以位于与第二部件34相对的第一部件32的孔38的端部处。
中间层44围绕轴线A同心地与内层42相邻;即中间层44围绕轴线A的整个周向与内层42相邻。中间层44可以具有管状形状。中间层44可以具有沿着轴线A伸长的圆形形状并且可以绕轴线A周向地围绕内层42。中间层44可以从第一端部68轴向地延伸到第二端部70。中间层44可以与内层42轴向共同延伸;即中间层44的第一端部68可以在内层42的第一端部64处,并且中间层44的第二端部70可以在内层42的第二端部66处。中间层44可以从内层42的第一端部64延伸到内层42的第二端部66。中间层44的第二端部70可以接触第二部件34,并且中间层44可以远离第二端部70轴向地延伸到中间层44的第一端部68。
中间层44和内层42可以在其之间具有边界50。边界50可以是内层42与中间层44的共享表面。边界50可以沿平行于轴线A的方向(即沿着轴向尺寸)具有非线性轮廓。换言之,边界50并不遵循内层42的第一端部64与内层42的第二端部66之间的直线。边界50的形状可以是旋转曲面,即通过围绕平面中的直线使平面中的曲线旋转而形成的表面。边界50可以是围绕轴线A旋转的非线性轮廓的旋转曲面。
继续参考图4-6,外层46可以包括管状部分72和凸缘部分74。管状部分72围绕轴线A同心地邻近中间层44;即管状部分72围绕轴线A的整个周向邻近中间层44。管状部分72具有管状形状。管状部分72可以具有沿着轴线A伸长的圆形形状并且可以绕轴线A周向地围绕中间层44。管状部分72可以从第一端部76轴向延伸到第二端部78。管状部分72的第一端部76可连接到凸缘部分74。管状部分72可与中间层44和/或内层42轴向地共同延伸;即管状部分72的第一端部76可以位于中间层44和/或内层42的第一端部64、68处,并且管状部分72的第二端部78可以位于中间层44和/或内层42的第二端部66、70处。管状部分72可以从中间层44和/或内层42的第一端部64、68延伸到中间层44和/或内层42的第二端部66、70。管状部分72的第二端部78可以接触第二部件34,并且管状部分可以远离第二端部78轴向地延伸到管状部分72的第一端部76。
中间层44和外层46的管状部分72可以具有其之间的边界52。边界52可以是中间层44和外层46的共享表面。边界52可以沿平行于轴线A的方向(即沿着轴向尺寸)具有非线性轮廓。换言之,边界52不遵循沿着中间层44的第一端部68与中间层44的第二端部70之间的轴向尺寸的直线。边界52的形状可以是旋转曲面,即通过围绕平面内直线使平面内的曲线旋转而形成的表面。边界52可以是围绕轴线A旋转的非线性轮廓的旋转曲面。
继续参考图4-6,外层46的凸缘部分74可以相对于轴线A从管状部分72径向向外延伸,即可以沿远离轴线A的径向方向延伸。凸缘部分74的外径可以大于外层46的管状部分72的外径。凸缘部分74可以具有在凸缘部分74的外径处周向延伸的斜面80。
凸缘部分74可以从邻近内层42的第一端部64的管状部分72相对于轴线A径向向内延伸,即可以沿着径向方向朝向轴线A延伸。凸缘部分74可以与中间层44相邻。凸缘部分74的内径可以小于管状部分72的内径。凸缘部分74的内径可以与内层42的内径相同,即与内层42的孔62的直径相同的尺寸。
外层46的凸缘部分74具有与内层42的第一端部64和中间层44的第一端部68的边界54。边界54可以是凸缘部分74、内层42或中间层44的共享表面。边界54可以沿与轴线A正交的方向(即沿着径向尺寸)具有非线性轮廓。换言之,边界54不遵循沿着从第一端部64处的凸缘或内层42的内径延伸到第一端部76处的管状部分72的内径的径向尺寸的直线。边界54的形状可以是旋转曲面,即通过围绕平面中的直线使平面中的曲线旋转而形成的表面。边界54可以是围绕轴线A旋转的非线性轮廓的旋转曲面。
参考图7和8,层42、44、46由纤维增强材料形成;即层42、44、46是纤维增强材料。层42、44、46可以由相同或不同的纤维增强材料形成,或者三个层42、44、46中的两个可以由相同的纤维增强材料(即相同类型的纤维增强材料)形成。作为另一个示例,所有三个层42、44、46可以由不同的纤维增强材料(即不同类型的纤维增强材料)形成。如上所述,纤维增强材料可以例如是纤维增强塑料或纤维增强聚合物,例如碳纤维、玻璃纤维或芳族聚酰胺纤维。纤维增强材料各自具有纤维82、84、86。纤维82、84、86可由例如碳、芳族聚酰胺、玻璃、聚丙烯腈、人造纤维等形成。纤维增强材料各自包括基体材料,并且纤维82、84、86设置在基体材料中。层42、44、46的基体材料可以例如是聚酯、环氧树脂、聚酰胺、聚碳酸酯、聚丙烯,乙烯基树脂、任何合适类型的聚合物等。
层42、44、46可以是一体的,即一起同时形成为一个整体单元。可选地,层42、44、46中的任何一个可以与其他层分开形成并且随后固定到其他层。
中间层44的纤维增强材料的纤维84在相对于轴线A的不同于内层42和外层46中的一个的纤维增强材料的纤维82、86的方向上延伸。例如,如果中间层44的纤维84径向延伸,则内层42或外层46的纤维82、86轴向地、周向地或者相对于轴向或周向以一定角度延伸。每根纤维都是纵长的,即在比在任何其他方向上长得多的一个方向上延伸。纤维集合(例如层42、44、46中的一个的纤维82、84、86)的方向是单独的纤维82、84、86的聚集方向,具体地是其中大部分纤维82、84、86取向的方向。
纤维82、84、86的密度可以在层42、44、46的不同位置之间变化。例如,如图7所示,相比在凸缘部分74的内径处或在管状部分72中,纤维82在外层46的凸缘部分74的外径处的密度可以更大。纤维82、84、86的密度是每单位体积的纤维数量。
参考图4-8,衬套88可以衬于孔62。衬套88可以是形成内层42的纤维增强材料的基体材料;即内层42的纤维增强材料的纤维86可以通过衬套88与孔62隔开。可选地,衬套88可以是与内层42的基体材料不同的材料。
参考图2和图3,接合结构30包括紧固件48。紧固件48可以位于穿过内层42的孔62和第二部件34的孔40。紧固件48接合第一部件32和第二部件34,即将第一部件32和第二部件34保持在一起。紧固件48由于插入件36而在安装时不接触第一部件32的纤维增强材料的任何纤维56。如图2和3所示,紧固件48可以是铆钉。当紧固件48安装到第一部件32和第二部件34时,紧固件48可以在两端包括头部90,头部90将内层42和外层44夹在一起。可选地,紧固件48可以是用于将第一部件32和第二部件34保持在一起的任何合适的类型,例如螺纹紧固件、销、夹子等。
如果第一部件32和第二部件34受到沿不同方向拉力,则紧固件48可阻止部件32、34分离。这些力将紧固件48推抵插入件36的孔62的一侧。如果力足够大,则插入件36可能变形或破裂。中间层44的纤维相对于内层或外层42、46的不同方向可允许中间层44压缩并且由此吸收能量,从而不会使插入件36破裂。
参考图7,插入件36的第一实施例可以包括相对于轴线A沿周向延伸的外层46的纤维82、相对于轴线A轴向延伸的中间层44的纤维84、和沿着相对于轴线A的周向与轴向之间的对角线的方向延伸的内层42的纤维86。换言之,外层46的纤维82在周向方向上延伸,即对于每个纤维,轴向尺寸z和径向尺寸r相对于周向尺寸θ是恒定的。中间层44的纤维84平行于轴线A延伸,即径向尺寸r和周向尺寸θ相对于轴向尺寸z是恒定的。内层42的纤维86沿着围绕轴线A的恒定半径的螺旋延伸,即径向尺寸r是恒定的,并且轴向尺寸是周向尺寸θ的线性函数,即z=kθ,其中k是常数。内层42可以包括在周向尺寸与轴向尺寸之间成对角的第一组纤维86a和在周向尺寸与轴向尺寸之间反向地成对角的第二组纤维86b。因此,对于第一组纤维86a,r是常数并且z=kθ,并且对于第二组纤维86b,r是常数并且z=–jθ,其中j和k是正常数。
参考图8,插入件36的第二实施例可以包括相对于轴线A沿周向延伸的外层46的纤维82、相对于轴线A径向延伸的中间层44的纤维84、和相对于轴线A沿周向延伸的内层42的纤维86。换言之,外层46和内层42的纤维82在周向上延伸,即对于每个纤维,轴向尺寸z和径向尺寸r相对于周向尺寸θ是恒定的。中间层44的纤维84正交于轴线A延伸,即轴向尺寸z和周向尺寸θ相对于径向尺寸r是恒定的。
已经以说明性方式描述了本公开,并且应当理解的是,已经使用的术语旨在描述词语的性质,而不是对其的限制。鉴于上述教导,本公开的许多修改和变化是可能的,并且本公开可以以与具体描述不同的方式实施。
