背景技术
在车辆行驶过程中，影响汽车舒适性的重要因素主要包括噪声和震动；其中，汽车车身及减震器的良好配合设计能够有效降低噪声和震动，从而提高汽车的NVH(Noise、Vibration、Harshness-噪声、振动与声振粗糙度)性能，进而提高汽车的综合制造质量。
一般来讲，汽车后减震器安装点的(动、静)刚度对后减震器的隔震量、以及降低路噪的能力有很大影响，当后减震器安装点的刚度越大时越有利于车内噪声和震动的控制。
现有结构中，当后减震器安装点受到来自于悬架中后减震器的激励时，震动和噪声的传播通道为从后减震器安装板至C柱加强板(也就是C柱)，由于C柱刚度有限，从而导致车内噪声和震动的控制效果不佳。
发明内容
有鉴于此，本发明旨在提出一种车身后部结构，以具有较好的传力效果，而可提高汽车的NVH性能。
为达到上述目的，本发明的技术方案是这样实现的：

具体实施例
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
为了便于对本实施例进行说明，以下所说的内侧是指朝向驾驶室内的一侧，外侧是指朝向驾驶室外的一侧。
下面将参考附图并结合实施例来详细说明本发明。
实施例一
本实施例涉及一种车身后部结构，应用于具有C柱和D柱的车身上，其主要包括侧围外板，配置于侧围外板内侧的侧窗内板，且由侧围外板和侧窗内板相连，而形成有C柱和D柱。于C柱和D柱下方还设有连接于一起的轮罩外板和轮罩内板，并于轮罩外板和轮罩内板之间连接有减震器安装板。本车身后部结构的主要改进点在于，其还包括C柱传力部、D柱传力部和轮罩内板传力部，以具有较好的传力效果，从而提高汽车的NVH性能。
基于以上的整体结构描述，本实施例的车身后部结构的一种示例性结构由图1和图2结合图9所示，其中图9示出了侧围外板11的结构示意图，其基本覆盖了车身左侧或右侧的大部分面积。
由图1和图2结合图10所示，其中图10示出了侧窗内板6的结构，其位于侧围外板11内侧，并靠上布置，侧窗内板6和侧围外板11固连于一起，从而形成有C柱和D柱。
接下来由图1至图3结合图10至图14对轮罩外板1和轮罩内板2的结构进行简要说明。其中图13示出了轮罩内板2的结构，图14示出了轮罩外板1的结构，轮罩外板1和轮罩内板2扣合固连于一起，两者位于C柱和D柱的下方，并均设置于侧围外板11的内侧。
由图11、图12结合图15和图16所示，于轮罩外板1和轮罩内板2之间连接有减震器安装板，并于减震器安装板上设置有减震器安装补强板301，本实施例中，减震器安装补强板301相对靠近轮罩内板2布置，并位于减震器安装板上表面上，以压缩轮罩内板2到轮胎中心的距离，使行李箱 空间最大化。减震器安装板的主要作用是安装现有的减震器，以用来抑制来自路面的冲击，改善汽车的行驶平顺性。
在此需要说明的是，以上的侧围外板11、侧窗内板6、C柱、D柱、减震器安装板3，轮罩外板1和轮罩内板2为现有结构，因此本实施例仅做了如上的简要介绍，以下将对本实施例的主要改进点进行详细说明。
C柱传力部10可由图1至图3并结合图17和图20所示，其中图20示出了C柱传力部10的具体结构，其顺沿C柱延伸设置，并连接于C柱和轮罩外板1之间，C柱传力部10和轮罩外板1的连接部位对应于减震器安装板3和轮罩外板1的连接部位设置，也就是说C柱传力部10和轮罩外板1的连接部位以及减震器安装板3和轮罩外板1的连接部位分置于轮罩外板1的两侧，且两者对应布置，其主要是将减震器安装板3承受的外力顺沿C柱及C柱传力部10朝向侧围上边梁4传递。
本实施例中，C柱传力部10由板状材质制成，其连接于侧窗内板6和轮罩外板1之间，且C柱传力部10与侧窗内板6的连接部位形成有第一空腔，C柱传力部10与轮罩外板1的连接部位形成有第二空腔。第一空腔和第二空腔相连通，并沿C柱传力部10的长度方向延展设置，也即沿传力方向延展设置，如此以加强C柱传力部10自身结构强度，从而起到较好的传力效果。
此外，结合图17所示，于轮罩内板2上还设置有轮罩内板前加强板201，轮罩内板前加强板201的上部与C柱传力部10连接，下部顺沿轮罩内板2向地板纵梁5延伸，以进一步改善传力效果。
D柱传力部可由图1至图3并结合图19所示，其中图19示出了D柱传力部的具体结构，其顺沿D柱延伸设置，并连接于车身的侧围上边梁4和轮罩外板1之间。D柱传力部和轮罩外板1的连接部位对应于减震器安装板3和轮罩外板1的连接部位设置，也就是说D柱传力部和轮罩外板1的连接部位以及减震器安装板3和轮罩外板1的连接部位分置于轮罩外板1的两侧，且两者对应布置，其主要是将减震器安装板3承受的外力顺沿D柱及D柱传力部朝向侧围上边梁4传递。
在此还需说明的是，为了起到较好的传力效果，C柱传力部10和轮罩外板1的连接部位以及D柱传力部和轮罩外板1的连接部位，分置于减震器 安装板3和轮罩外板1的连接部位的前部和后部。即C柱传力部10和轮罩外板1的连接部位，设置于减震器安装板3与轮罩外板1的连接部位的前部；D柱传力部和轮罩外板1的连接部位，设置于减震安装板3和轮罩外板1的连接部位的后部。
仍参照图19所示，为了便于安装布置，本实施例中，D柱传力部包括上下布置并连接于一起的上D柱加强板801和下D柱加强板802，且上D柱加强板801的上部与侧围上边梁4连接，下D柱加强板802的下部与轮罩外板1连接，以使减震器安装板3承受的外力能够顺沿D柱及D柱传力部朝向侧围上边梁4传递。
为了起到较好的传力效果，由图4至图6结合图8所示，上D柱加强板801与侧窗内板6之间，以及下D柱加强板802与侧窗内板6之间均形成有空腔，且空腔随D柱传力部的长度方向延展设置，也即沿传力方向延展设置，如此以加强D柱传力部自身结构强度，从而进一步提高传力效果。在此需要注意，图4及图6仅是为了清楚示出C柱传力部10、D柱传力部以及下述的轮罩内板传力部组合后的整体形状，其实际位置关系参照本说明书的文字描述和其他附图。
以上结构中，C柱传力部10和D柱传力部被配置于侧围外板11和侧窗内板6之间，该位置不占用存储空间，可有效提高空间利用率。
最后对轮罩内板传力部的结构进行说明，可参照图1至图3及图17和图18所示，其中图17和图18示出了轮罩内板传力部的具体结构，其固设于轮罩内板2上，并呈倒置的“Y”形。轮罩内板传力部的上部自由端与D柱连接，两个下部自由端于车辆长度方向上前后布置，并分别与车身的地板纵梁5连接，以将减震器安装板承受的外力向地板纵梁5传递。
本实施例中，结合图3至图7所示，轮罩内板传力部配置于轮罩内板2的内侧，并包括具有上部自由端和前部的下部自由端的主加强板901，以及具有后部的下部自由端，并与主加强板901的中部连接的副加强板902，且主加强板901和副加强板902的连接部位，对应于轮罩内板2和减震器安装板3的连接部位设置，两者分置于轮罩内板2的两侧，以起到较好的提高自身结构强度的作用，并起到较好的传力效果。该结构中，为了便于布置，主加强板901和副加强板902的靠近地板纵梁5的部位可由两段上下连接而 成，当然也可为一体结构。
为了起到较好的传力效果，于轮罩内板传力部和轮罩内板2之间形成有空腔，且空腔随轮罩内板传力部的形状延展设置。具体来讲，主加强板901和轮罩内板2之间，以及副加强板902和轮罩内板2之间均形成有空腔，且空腔呈倒置的“Y”形，以有效提高自身结构强度，从而起到更好的传力效果。
以上描述的车身后部结构，传力通道由四条环形通道和八条纵梁共同交织组成，四条“环”型通道分别是减震器安装部位的近似“X”型的传力通道连接地板横梁7、顶盖加强板、顶盖后横梁，构成的两条完整“环”型传力通道，以及背门门环和座椅安装横梁部位连接C柱加强部的“环”型传力通道。八条纵梁分布是两个侧围上边梁4、两个侧窗内板6下部、两个地板纵梁5以及两个地板面板加强梁12。
本发明的车身后部结构，可解决减震器安装部位刚度小的问题，使车身后部形成一个完整的整体，能有效提高车身后部整体抗扭转能力，间接地提高汽车在舒适性、耐久性、操控性、安全性等方面的表现。
此外，本车身后部结构同时设置有C柱传力部10、D柱传力部和轮罩内板传力部，能够优化车身后部结构的机械性能，实现力在车身后部结构上的有效传递，提高车辆的NVH性能，并可利用最轻的结构提升扭转刚度，还不会出现局部疲劳开裂问题，具有较好的实用性。
实施例二
本实施例提供了一种车辆，于该车辆上配置有如实施例一的车身后部结构。本实施例的车辆，通过应用实施一的车身后部结构，可起到较好的传力效果，从而提高车辆的NVH性能。
在此处所提供的说明书中，说明了大量具体细节。然而，能够理解，本发明的实施例可以在没有这些具体细节的情况下被实践。在一些实例中，并未详细示出公知的方法、结构和技术，以便不模糊对本说明书的理解。
在权利要求中，不应将位于括号之间的任何参考符号构造成对权利要求的限制。单词“包含”不排除存在未列在权利要求中的元件或步骤。位于元件之前的单词“一”或“一个”不排除存在多个这样的元件。本发明可以借助于包括有若干不同元件的硬件以及借助于适当编程的计算机来实现。在列举了若 干装置的单元权利要求中，这些装置中的若干个可以是通过同一个硬件项来具体体现。单词第一、第二、以及第三等的使用不表示任何顺序。可将这些单词解释为名称。
最后应说明的是：以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
