The invention discloses a frame structure, a battery pack and a vehicle, an inner cavity of a frame is divided into a control cabin and a battery cabin through a first cross beam, at least one edge beam, located in the Y direction, of the frame is provided with a vertical surface part, a guide part and a hanging part, and the vertical surface part is close to the control cabin and the battery cabin and serves as a mounting foundation of other parts of the battery pack; the vertical surface part is connected to the first crossbeam. The guiding part is located between the vertical surface part and the hanging part and plays a role in guiding deformation, one end of the guiding part is connected to the outer vertical surface of the vertical surface part, and the other end of the guiding part is connected to the hanging part. The inner cavity of the mounting part can be collapsed under the action of collision force, under some circumstances, the mounting part can also deform in the height direction of the vehicle under the guide action of the guide part, for example, upward bending and overturning or downward bending and overturning are conducted, and short-time energy release of the collision working condition can be well absorbed and dissipated in the process; different requirements of whole vehicle collision and battery pack extrusion on the battery box body are met, and internal parts of the frame are effectively protected.
本申请公开了一种框架结构、电池包以及车辆,边框的内腔通过第一横梁分隔为控制舱和电池舱,边框的位于Y向的至少一个边梁设有立面部、引导部和挂载部,立面部靠近于控制舱和电池舱,作为电池包其他部件的安装基础,立面部连接于第一横梁。引导部位于立面部与挂载部之间,起到引导变形的作用,引导部的一端连接于立面部的外立面,另一端连接于挂载部。挂载部内部型腔,能够在碰撞力的作用下发生缩溃,某些情况下,挂载部也能够在引导部的引导作用下向车辆的高度方向发生形变,例如向上弯曲翻转或向下弯曲翻转,该过程中能较好的吸收、耗散碰撞工况的短时能量释放,满足整车碰撞和电池包挤压对电池箱体的不同需求,有效保护边框内部零件。
