技术领域
本公开涉及交通工具领域，具体地涉及一种车辆。
背景技术
汽车车身一般分为承载式车身和非承载式车身两种。具有非承载式车身的汽车包括刚性车架(又称为底盘大梁架)和安装在刚性车架上的车身。在具有非承载式车身的汽车中，发动机、传动系统的一部分、车身等总成部件都是用悬挂装置固定在刚性车架上，刚性车架通过前后悬挂装置与车轮连接。虽然非承载式车身具有较好的平稳性和安全性，但是非承载式车身的汽车比较笨重、质量大、高度高，因此一般用在货车、客车和越野车上，也应用在部分高级轿车上。
具有承载式车身的汽车没有刚性车架。承载式车身包括底板、车顶以及连接在底板和车顶之间的立柱。立柱包括位于汽车的前门的前侧的A柱、位于汽车的前门和后门之间的B柱和位于后门的后侧的C柱。承载式车身的底板、车顶和立柱形成一个整体结构。汽车的发动机、用于安装前轮的前悬挂装置、用于安装后轮的后悬挂装置和传动系统的一部分均安装在承载式车身上。承载式车身的汽车具有质量小、高度低、装配容易等优点，大部分轿车均采用承载式车身结构。
承载式车身的底板和车顶均包括车身结构件和罩设在车身结构件上的车身覆盖件。大部分的车身覆盖件和车身结构件采用冲压成型工艺制造，承载式车身的尺寸以及形状受到各个车身结构件和车身覆盖件的尺寸和形状的影响。因此，在需要改变承载式车身的汽车型号时，需要改变用以制造车身结构件和车身覆盖件的多种冲压磨具，从而使得承载式车身的尺寸改变需 要巨大的成本。

具体实施方式
下面将结合本公开实施例的附图，对本公开实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，而不作为对本公开的任何限制。基于本公开的实施例，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，都属于本公开保护的范围。
本文中的“多个”是指两个或者两个以上；“纵向”是指车辆的长度方向；“横向”是指车辆的宽度方向；“前”为车头方向，“后”为车尾方向，。
图1示出本公开实施例的车辆的框架的拆解图。图2示出本公开实施例的车辆的结构示意图。图3示出本公开实施例的车辆的结构的立体图。
参考图1、2和3，本公开实施例的车辆1包括底盘10和设置在底盘10上的用于向车轮提供驱动力的驱动单元。底盘10包括底盘本体13、连接在底盘本体13的前端的前底盘模块单元11和连接在底盘本体13的后端的后底盘模块单元12。底盘本体13沿车辆1的纵向是细长形的，例如为线形的。
前底盘模块单元11通过前悬挂系统71与前轮73相连。后底盘模块单元12通过后悬挂系统72与后轮74相连。
前底盘模块单元11和后底盘模块单元12中的一个或两个设置有驱动单元。在前底盘模块单元11中设置驱动单元的情况下，车辆1为前驱的；在后底盘模块单元12中设置驱动单元的情况下，车辆1为后驱的。在前底盘 模块单元11和后底盘模块单元12中均设置驱动单元的情况下，车辆为四驱的。在本公开的实施例中，示出的车辆1为四驱的，在此情况下，设置在前底盘模块单元11中的驱动单元称为前驱动单元33，设置在后底盘模块单元11中的驱动单元称为后驱动单元34。
在本实施例中，由于底盘10包括底盘本体13和分别连接在底盘本体13的前后两端的前底盘模块单元11和后底盘模块单元12等多个独立的组成单元，所以在需要生产轴距不同的车型时，仅需改变底盘10的一个或多个组成单元并将多个组成单元依次连接，即可形成不同尺寸的底盘10。同样，可以通过更换底盘模块单元上的悬挂摇臂长度和悬挂系统高度，来改变车辆的轮距和离地间隙等。因此，本实施例的底盘10易于实现不同车型的车辆的规模化生产，并且降低了改变车型的成本。
前底盘模块单元11包括第一壳体110，第一壳体110上设置有第一通孔111，第一通孔111允许用于带动前轮73转动的第一传动装置61穿过。第一传动装置61沿车辆的横向由第一壳体110内部朝第一壳体110外侧延伸，第一传动装置61的远离第一壳体110的一端与前轮73连接。参见图8，第一传动装置61包括第一传动轴610。
第一壳体110可以在内部设置有第一动力舱室31，第一动力舱室31容纳用于驱动前轮73的前驱动单元33。第一壳体110上还设置有用于支撑前驱动单元33的支撑结构。
图9示出本公开实施例的前驱动单元33的外部结构示意图。前驱动单元33包括第一电动机331。第一传动装置61的远离前轮73的一端与前驱动单元33传动配合，以使前驱动单元33驱动前轮73转动。
可选地，前驱动单元33和第一传动装置61之间还设置有减速器、差速器和变速器等(未示出)。
本实施例中，前底盘模块单元11的两侧均设置有第一连接部件112。第一连接部件112能够与用以支撑前轮73的前悬挂系统71可拆卸地连接。参考图11，第一连接部件112设置在前底盘模块单元11的侧面上。前悬挂系统71与第一连接部件112连接，并沿车辆1的横向朝远离前底盘模块单元11的方向延伸。前悬挂系统71的远离前底盘模块单元11的一端与前轮73 连接。
图8示出本公开的实施例的车辆的前轮和前悬挂系统的示意图。在图8中，前悬挂系统71包括多个第一杆体711，第一杆体711的第一端与前底盘模块单元11的第一连接部件112连接，第一杆体711的第二端与前轮73连接。至少部分第一杆体711相对于车辆的横向倾斜，以形成三角形稳定结构。
第一连接部件112上可以设有与多个第一杆体711的第一端连接的多个第一安装部115，多个第一安装部115沿第一传动装置61的径向布置。多个第一杆体711的第一端与不同的第一安装部115连接，使得多个第一杆体711相对于车辆1的横向倾斜的角度不同，多个第一杆体711的第二端与前底盘模块单元11之间的垂直距离也就不同，也即实现了前悬挂系统71的长度的调节。因此实现了两个前轮73之间的距离的调节。
可选地，前轮73上设置有用于连接多个第一杆体711的第二端的多个第二安装部731，多个第二安装部731沿前轮73的径向布置。通过多个第一杆体711的第二端与不同的第二安装部731连接，也可以调节第一杆体711相对于车辆1的横向倾斜的角度，从而调节前悬挂系统71的长度，进而调节了两个前轮73之间的间距。
同理，通过调节第一杆体711的两端分别与前底盘模块单元11和前轮73的安装位置，也可以实现前底盘模块单元11离地间隙的调整。
由此可见，本实施例的车辆的前悬挂系统的长度是可调的，以改变车辆的轮距。进一步地，车辆1的前底盘模块单元11的离地间隙也是可调的，以改变车辆1的离地间隙。因此，本实施例的车辆1的底盘10以及前悬挂系统71经过简单的调整就能够用于不同的离地间隙以及不同轮距的车辆。
当然，车辆的底盘10还可以与不同的前悬挂系统71和后悬挂系统72配合，以改变车辆的宽度以及离地间隙，从而改变车辆的轮距和离地间隙。
参考图1和图3，前底盘模块单元11的第一壳体110的顶面的高度由前至后渐增，并且第一壳体110的顶面与底盘本体13的顶面平滑过渡，以利于实现车辆的流线形设计。可选地，第一壳体110的顶面与第一壳体110的侧面平滑过渡。
在本实施例中，底盘10的前底盘模块单元11、底盘本体13和后底盘 模块单元12等多个组成单元的材质均为铝合金。相邻的两个组成单元可以采用焊接、铆接或螺栓连接的方式连接在一起。
另外，底盘10的多个组成单元的材质可以均为碳纤维，相邻的两个部件可以采用粘接或铆接的方式连接。相邻两个组成单元中的一个的材质为碳纤维，另一个的材质为铝合金，不同的材质的相邻两个组成单元可以采用粘接或铆接的方式连接在一起。
底盘本体13上设置有驾驶员座舱131。底盘本体13的宽度仅稍大于驾驶员座舱131的宽度。底盘本体13的外壳包括在车辆的横向上间隔设置的两个侧壁1310，两个侧壁1310之间形成驾驶员座舱131。
底盘本体13上还设置有电力系统舱132，电力系统舱132用于安置车辆的电力系统或其他零部件。电力系统用于向车辆的驱动单元提供电力。本实施例中，电力系统包括发电系统、储能系统(例如蓄电池)、电力传输系统和/或电力控制系统。电力系统舱132位于驾驶员座舱131的后方且与驾驶员座舱131之间具有特定间距。因此，通过改变电力系统舱132与驾驶员座舱131之间的间距，可以改变底盘本体13的长度，从而改变车辆的轴距。
图3示出本公开的实施例的车辆的结构的立体图。图4示出本实施例的后底盘模块单元12的结构示意图。参考图1、图3和图4，后底盘模块单元12包括第二壳体122，第二壳体122上设置有第二通孔121，第二通孔121允许用于带动后轮74转动的第二传动装置62穿过。第二传动装置62沿车辆的横向由第二壳体122的内部朝第二壳体122的外侧延伸，第二传动装置62的远离第二壳体122的一端与车辆1的后轮74连接。如图10所示，第二传动装置62包括第二传动轴620。
第二壳体122包括第二动力舱室32，第二动力舱室32容纳用于驱动后轮74的后驱动单元34。后驱动单元34设置在第二壳体122内。第二壳体122上还设置有用于支撑后驱动单元34的支撑结构123。
在本实施例中，后驱动单元34包括第二电动机341。第二传动装置62的远离后轮74的一端与后驱动单元34传动配合，以使后驱动单元34驱动后轮74转动。
可选地，后驱动单元34和第二传动装置62之间还可以设置有减速器、 差速器和变速器等(未示出)。
图12示出本公开的实施例的位于后驱动单元外部的第二连接部件的构造示意图。第二连接部件124位于后驱动单元34外部并且设置在后底盘模块单元12的两侧，第二连接部件124包括多个第三安装部125，多个第三安装部125能够与用于支撑后轮74的后悬挂系统72可拆卸地连接。后悬挂系统72靠近后底盘模块单元12的一端与第二连接部件124连接，并且沿车辆1的横向朝远离后底盘模块单元12的方向延伸。后悬挂系统72的远离后底盘模块单元12的一端与后轮74连接。
后悬挂系统72包括多个第二杆体721，第二杆体721的第一端与第二连接部件124上的多个第三安装部125连接，第二杆体的721的第二端与后轮74连接。至少部分第二杆体721相对于车辆1的横向倾斜，以形成三角形稳定结构。
可选地，与第二杆体721的第一端连接的多个第三安装部125可以设置在第二壳体122上，多个第三安装部125沿第二传动装置62的径向布置。多个第二杆体721的第一端与不同的第三安装部125连接，使得多个第二杆体721相对于车辆1的横向倾斜的角度不同，多个第二杆体721的第二端与后底盘模块单元12之间的垂直距离也就不同，也即实现了后悬挂系统72的长度的调节。因此实现了两个后轮74之间的距离的调节。
可选地，后轮74上可以设置有用于与多个第二杆体721的第二端连接的多个第四安装部741，多个第四安装部741沿后轮74的径向布置，多个第二杆体721的第二端与不同的第四安装部741连接，可以调节第二杆体721相对于车辆1的横向倾斜的角度，从而调节后悬挂系统72的长度，进而能够调节两个后轮74之间的间距。
同理，通过调节第二杆体721的两端分别与后底盘模块单元12和后轮74的安装位置，也可以实现后底盘模块单元12离地间隙的调整。
由此可见，本实施例的车辆的后悬挂系统72的长度是可调的，以改变车辆的轮距。进一步地，车辆的底盘10的离地间隙也是可调的，以改变车辆的离地间隙。本实施例的车辆的底盘10以及后悬挂系统72经过简单的调整就能够用于不同离地间隙以及不同轮距的车辆。
综上所述，本实施例的车辆的悬挂系统的长度是可调的，以改变车辆的轮距。
车辆的底盘10可以与不同的前悬挂系统71和后悬挂系统72配合，以改变车辆的宽度以及离地间隙，从而改变车辆的轮距和离地间隙。
可选地，前悬挂系统71和后悬挂系统72中至少一个中的杆体是可伸缩的，使得前悬挂系统71和后悬挂系统72中至少一个的长度是可调节的。
如图1、5和7所示，驾驶员座舱131是底盘本体13的外壳围成的腔室，驾驶员座舱131的上端是开口端。
为了防止车辆在行驶的过程中因发生侧翻而产生滚动，车辆底盘还包括罩设在驾驶员座舱131的上方的防滚架2，防滚架2与底盘本体13可拆卸地连接。防滚架2能够在车辆发生意外时有效地保护驾驶员与乘客的安全。
防滚架2包括平行且间隔设置的两个拱形杆状部件21和连接在两个拱形杆状件之间的多个结构加强杆22。结构加强杆22的两端分别与两个拱形杆状部件21连接。
拱形杆状部件21的前端和后端均与底盘本体13连接，拱形杆状部件21的前端位于驾驶员座舱131的前方，拱形杆状部件的后端位于驾驶员座舱131的后方。
防滚架2还包括两个斜支撑杆23，两个斜支撑杆23的第一端与底盘本体13连接，位于驾驶员座舱131的前方，并且与拱形杆状部件21的前端在车辆的横向上间隔设置。两个斜支撑杆23的第二端与两个拱形杆状部件21分别连接，以增加防滚架2的结构强度。
车辆底盘10还包括设置在底盘本体13的侧部的乘客座舱5。乘客座舱5与底盘本体13可拆卸地连接。
车辆底盘10可以仅包括设置在底盘10一侧的乘客座舱5，也可以包括分别设置在底盘10的两侧的乘客座舱5。该乘客座舱也可以设计为行李舱。
在本实施例中，驾驶员座舱131的两侧均设置有乘客座舱5。驾驶员座舱131位于车辆的横向的中部。分别位于驾驶员座舱131两侧的两个乘客座舱5相对于底盘本体13对称设置。
本实施例中，底盘10的两侧均设置有乘客座舱5，乘客座舱5比驾驶 员座舱131靠近底盘10的后端，以防止乘客座舱5遮挡驾驶员的视野。
图5示出本公开实施例的车辆底盘10的底盘本体13和乘客座舱5没有连接在一起时的结构示意图。图6示出本公开的实施例的车辆底盘10的底盘本体13和乘客座舱5连接在一起时的结构示意图。
本实施例中，底盘本体13和乘客座舱5的材质均为铝合金。底盘本体13和乘客座舱5可以采用铆接、焊接或螺栓连接等方式连接在一起。
可选地，底盘本体13和乘客座舱5中之一的材质为铝合金，另一个的材质为碳纤维。或者，底盘本体13和乘客座舱5的材质均为碳纤维。底盘本体13和乘客座舱5可以采用粘接或铆接等方式连接在一起。
在本实施例中，车辆底盘10还包括用于连接底盘本体13和乘客座舱5的连接件8。
图7示出本公开实施例的车辆底盘的用于连接底盘本体13和乘客座舱5的连接件8的结构示意图。如图7所示，连接件8包括与底盘10连接的第一板体81、与乘客座舱5连接的第二板体82和连接第一板体81和第二板体82的立板83。第一板体81与立板83的上端连接，第二板体82与立板83的下端连接。
第一板体81上设置有用于连接底盘10的第一螺栓孔811。第一板体81与底盘10的底部通过多个第一螺栓连接。
第二板体82上设置有用于连接乘客座舱5的第二螺栓孔821。第二板体82与乘客座舱5的底部通过多个第二螺栓连接。
本实施例中，车辆底盘10还包括连接在底盘本体的前端设置的前缓冲部件41和连接在底盘本体的后端的后缓冲部件42，以在车辆发生意外碰撞时保护车辆以及车辆内的驾驶员和乘客。
以上所述仅为本公开的示例性实施例，并不用以限制本公开。凡在本公开的精神和原则之内所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
