本申请要求比亚迪股份有限公司于2022年07月29日提交的、名称为“车辆”的、中国专利申请号“202210911282.5”的优先权。
技术领域
本申请涉及电动车辆技术领域，具体涉及一种车辆。
背景技术
为了保护电动车辆的电池包，通常将电池包设置在车底。相关技术中，电池包通过设置在两侧的连接点与车身总成在宽度方向的两侧进行连接。然而，电池包仅在车身总成宽度方向与车身总成连接，使得电池包无法有效的提高车身的抗扭性能。
发明内容
本申请旨在至少在一定程度上解决相关技术中的技术问题之一。
为此，本申请提出一种车辆。
根据本申请的车辆，包括左前纵梁以及右前纵梁、左A柱以及右A柱、风窗上横梁和电池包，所述左前纵梁与所述右前纵梁在车辆的宽度方向上间隔设置，所述左A柱以及右A柱在车辆的宽度方向上间隔设置，所述左前纵梁与所述左A柱的下段连接，所述右前纵梁与所述右A柱的下段连接，所述风窗上横梁的两端分别连接所述左A柱的上段以及所述右A柱的上段，所述电池包的前端分别与所述左前纵梁以及所述右前纵梁直接连接，其中，所述左前纵梁、右前纵梁、左A柱、右A柱、风窗上横梁以及电池包形成第一A柱环状传力结构。
根据本申请实施例的车辆，通过将电池包的前端分别与左前纵梁以及右前纵梁直接连接，使得左前纵梁、电池包、右前纵梁、右A柱、风窗上横梁和左A柱在乘员舱前方和电池包前方上部形成第一A柱环状传力结构，由于电池包本身具有较大的强度和刚度，因此，将电池包作为第一A柱环状传力结构中的一部分，能够有效的增强第一A柱环状传力结构的强度，提高其抗扭能力，提高车辆的扭转强度。
本申请的附加方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本申请的实践了解到。
