Abstract

本申请公开一种搭载高压电池的车辆的车身。该车身包括：后横梁，沿车身的横向方向安装在前座位的后侧的下方；前横梁，沿车身的横向方向安装在后横梁的前方；以及多个纵向支撑构件，被安装为支撑高压电池的底部，并在车身的纵向方向上连接前横梁和后横梁，其中高压电池安装在前横梁和后横梁之间。

Description

搭载高压电池的车辆的车身
技术领域
本公开涉及一种诸如电动车辆或混合动力车辆的搭载高压电池的车辆的车身结构。
背景技术
通常，电动车辆或混合动力车辆需要搭载高压电池。然而，由于高压电池具有相对较大的体积和重量，并且需要具有水密性，因此难以确保车身中高压电池的搭载位置和空间。
此外，车身需要具有足够的刚度以承受例如由碰撞引起的各种外力。
本部分中公开的信息仅用于增强对常规背景的理解，并且不应被认为是对该信息构成本领域技术人员已知的相关技术的承认或任何形式的建议。
发明内容
因此，鉴于上述问题提出本公开，并且本公开的目的是提供一种搭载高压电池的车辆的车身，其能够在不减少车辆中乘坐者可使用的内部空间的情况下安全且牢固地搭载高压电池，并且通过安装在车身上的高压电池来提高刚度，从而降低车身由于例如由碰撞引起的各种外力的变形程度，并改善了车辆的噪声、振动和声振粗糙度(NVH)性能、乘坐舒适性和可操纵性。
根据本公开，上述和其它目的可以通过提供一种搭载高压电池的车辆的车身来实现，该车身包括：后横梁，沿车身的横向方向安装在前座位的后侧的下方；前横梁，沿车身横向方向安装在后横梁的前方；以及多个纵向支撑构件，被安装为支撑高压电池的底部，并在车身的纵向方向上连接前横梁和后横梁，其中高压电池安装在前横梁和后横梁之间。
多个纵向支撑构件中的每一个可以被安装为沿车身的长度方向排列，并且连接到前纵后构件的后端，前纵后构件从设置在车身的前部的前纵梁沿车身的长度方向向后延伸。
前横梁和后横梁中的每一个可以在其相对的端部处联接到车身的纵梁。
从设置在车身的前部的前纵梁沿车身的长度方向向后延伸的前纵后构件的后端可以联接到前横梁，并且多个纵向支撑构件中的每一个可以在前横梁上连接到前纵后构件的后端。
高压电池可以包括：隧道部，沿车身的纵向中心轴线延伸，并且形成为向上凹陷且向下开口；以及存储部，形成在隧道部的相对侧上，以容纳构成高压电池的电池模块。
隧道部可以被配置为使相对侧上的存储部中的内部空间通过隧道部彼此连通。
车身可以进一步包括：多个横向支撑构件，被配置为支撑高压电池，并且多个横向支撑构件可以设置在高压电池的下方，并可以在车身的横向方向上从隧道部延伸到车身的纵梁。
高压电池的存储部可以直接联接到车身的纵梁。
高压电池的隧道部的宽度可以形成为比形成在隧道部的相对侧上的每个存储部的宽度窄。
高压电池的隧道部的横截面可以形成为倒U形，以在车身的向下方向上开口。
附图说明
从以下结合附图的详细描述中，将更清楚地理解本公开的上述和其它目的、特征和其它优点，其中：
图1是从下方观察的根据本公开的搭载高压电池的车辆的车身的视图；
图2是沿图1中的线II-II截取的高压电池的截面图；以及
图3是示出利用图1所示的前纵后构件和纵向支撑构件确保车身在纵向方向上的刚度的结构的视图。
具体实施方式
现在将详细参照本公开的优选实施例，附图中示出其示例。在所有附图中，将尽可能使用相同的附图标记来表示相同或相似的部件。
参照图1至图3，根据本公开的搭载高压电池1的车辆的车身包括：后横梁3，沿车身的横向方向安装在前座位S的后侧的下方；前横梁5，沿车身的横向方向安装在后横梁3的前方；以及多个纵向支撑构件7，被安装为支撑高压电池1的底部，并在车身的前后方向上连接前横梁5和后横梁3。高压电池1安装在前横梁5和后横梁3之间。
前横梁5和后横梁3中的每一个在其相对的端部处直接联接到车身的纵梁9。
因此，高压电池1安装在由车身的相对侧的两个纵梁9、前横梁5和后横梁3形成的平面空间中。因此，设置在高压电池1周围的上述部件从根本上保护高压电池1免受外力的影响。
每个纵向支撑构件7被安装为沿车身的长度方向排列，并且连接到前纵后构件13的后端，前纵后构件13从设置在车身的前部的前纵梁11沿车身的长度方向向后延伸。
因此，如图3所示，前纵后构件13和每个纵向支撑构件7用作如“A”所示沿车身的纵向方向伸长并连接的刚度加强件，从而起到提高车身在纵向方向上的整体刚度的作用。
从设置在车身的前部的前纵梁11沿车身的长度方向向后延伸的前纵后构件13的后端联接到前横梁5。每个纵向支撑构件7在前横梁5上连接到前纵后构件13的后端。
因此，前纵后构件13和每个纵向支撑构件7的联接结构可以更牢固地固定在前横梁5上。
高压电池1包括：隧道部1-1，沿车身的纵向中心轴线延伸，并且形成为向上凹陷且向下开口；以及存储部1-3，形成在隧道部1-1的相对侧上，以容纳构成高压电池1的电池模块1-2。
隧道部1-1被配置为使在形成在隧道部1-1的相对侧上的存储部1-3中的内部空间通过隧道部1-1彼此连通，从而实现容纳在存储部1-3中的电池模块1-2之间的电连接。
在该实施例中，如图2所示，高压电池1的隧道部1-1的横截面形成为倒U形，以在车身的向下方向上开口。具体地，高压电池1的隧道部1-1具有两个倒U形横截面，两个倒U形横截面彼此垂直间隔开，以使两侧的存储部1-3通过两个倒U形横截面之间的间隙彼此连通。
隧道部1-1本身由于其横截面为倒U形而起到提高高压电池1的刚度的作用。另外，两个倒U形横截面彼此垂直隔开预定间隙的隧道部1-1的结构起到进一步提高高压电池1的刚度的作用。
因此，当具有上述高刚度结构的高压电池1通过每个纵向支撑构件7连接到前纵后构件13、前横梁5和后横梁3时，如上所述，高压电池1本身起到提高车身的刚度的作用。
另外，多个横向支撑构件15设置在高压电池1的下方，并在车身的横向方向上从隧道部1-1延伸到车身的纵梁9以支撑高压电池1，从而使车身更牢固地支撑高压电池1，并且进一步提高了车身本身的刚度。
当然，可以可选地设置横向支撑构件15。例如，可以省略横向支撑构件15，并且可以在高压电池1的存储部1-3的侧面形成凸缘结构等并可以直接联接到车身的纵梁9。
高压电池1的隧道部1-1的宽度可以形成为比形成在隧道部1-1的相对侧上的每个存储部1-3的宽度窄，从而充分确保存储部1-3的容量以充分确保用于在存储部1-3中搭载电池模块1-2的搭载空间。
作为参考，在后轮驱动车辆的情况下，隧道部1-1的下侧可以用作可以安装诸如驱动轴17的动力传递部件的空间，在图1中示出该示例。
从以上描述中显而易见的是，本公开提供了一种搭载高压电池的车辆的车身，其能够在不减少车辆中乘坐者可使用的内部空间的情况下安全且牢固地搭载高压电池，并且通过安装在车身上的高压电池来提高刚度，从而降低车身由于例如碰撞的各种外力的变形程度，并改善了车辆的噪声、振动和声振粗糙度(Noise Vibration Harshness,NVH)性能、乘坐舒适性和可操纵性。
尽管出于说明性目的公开了本公开的优选实施例，但是本领域技术人员将理解的是，在不脱离如所附权利要求书中公开的本公开的范围和宗旨的情况下，可以进行各种修改、添加和替换。
