The embodiment of the invention belongs to the technical field of automobile manufacturing, and particularly relates to a chassis, a body in white and an electric automobile. The embodiment of the invention aims to solve the problem that the maintenance difficulty of the electric vehicle is relatively high. According to the chassis, the body in white and the electric automobile, the front ends of the first threshold beam and the second threshold beam of the chassis are connected with the front wall assembly, the second threshold beam comprises the first inner beam and the first outer beam, the front end of the first inner beam is connected with the front wall assembly, and the front end of the first outer beam is detachably connected with the front wall assembly; and the first inner beam is detachably connected with the first outer beam. In this way, when the side face of the electric automobile is collided, due to the fact that the first outer beam is located on the outer side of the body-in-white, the first outer beam deforms after being collided; after the first outer deformation, the first outer beam can be detached from the front wall assembly, then the first outer beam is replaced, the whole second doorsill beam does not need to be detached, and then the maintenance difficulty of the electric automobile is reduced.

    本申请实施例属于汽车制造技术领域,具体涉及一种底盘、白车身及电动汽车。本申请实施例旨在解决电动汽车的维修难度较大的问题。本实施例提供的底盘、白车身及电动汽车,底盘的第一门槛梁和第二门槛梁的前端均与前围组件连接,第二门槛梁包括第一内梁和第一外梁,第一内梁的前端与前围组件连接,第一外梁的前端与前围组件可拆卸的连接,第一内梁与第一外梁之间可拆卸的连接。如此,电动汽车在发生侧面碰撞时,由于第一外梁位于白车身的外侧,第一外梁受到碰撞后发生变形;在第一外变形后可以将第一外梁由前围组件上拆卸下来,进而更换第一外梁,无需拆卸整个第二门槛梁,进而降低了电动汽车的维修难度。
