The invention relates to the technical field of vehicle body structures, and discloses a vehicle body structure for battery pack protection and a vehicle. The front ends and the rear ends of two doorsill longitudinal beams are connected through a doorsill connecting beam structure and a second-row seat front mounting cross beam, and the middle positions of the two doorsill longitudinal beams are connected through a front seat front cross beam structure and a front seat rear cross beam structure; four supporting paths in the side collision direction of the vehicle body are formed; the front ends of the two threshold longitudinal beams are connected with the front longitudinal beam assembly through threshold connecting beam structures, the threshold connecting beam structures are connected with the second row of seat front installation cross beams through two sets of front floor longitudinal beams, and four supporting paths in the driving direction are formed. By means of the four-transverse and four-longitudinal structural design, a vehicle body forms a structural frame with high rigidity, the battery pack is fixed in the structural frame, when a whole vehicle collides, collision force is transmitted to a battery pack body as little as possible through structural parts of the structural frame, extrusion to battery cells in the battery pack is reduced, and the battery pack is prevented from being damaged or being on fire.
本发明涉及车身结构技术领域,公开了一种电池包保护用车身结构及车辆,本发明的两门槛纵梁前端和后端之间通过门槛连接梁结构和第二排座椅前安装横梁连接,两门槛纵梁中间位置通过前座椅前横梁结构和前座椅后横梁结构连接,形成车身侧碰方向的四条支撑路径;两门槛纵梁前端均通过门槛连接梁结构连接前纵梁总成,门槛连接梁结构与第二排座椅前安装横梁之间通过两组前地板纵梁连接,形成行车方向的四条支撑路径;通过“四横四纵”的结构设计,使得车身形成一个刚度较高的结构框架,将电池包固定在结构框架中,在整车发生碰撞时,通过结构框架结构件,将碰撞力尽可能少的传递给电池包本体,减少对电池包内部电芯挤压,预防电池包损坏或起火现象。
