The embodiment of the invention discloses a protective base for a battery pack, a battery pack box body, a battery cell directly integrated battery pack and a vehicle, the protective base for the battery pack comprises a main body and an anti-collision structure, the main body comprises a top plate, a bottom plate and side plates, and the top plate, the bottom plate and the side plates jointly define a first accommodating space; the anti-collision structure is arranged in the first containing space and comprises a plurality of first anti-collision substructures and a plurality of second anti-collision substructures which are alternately arranged in the first direction and connected with one another. A plurality of liquid cooling channels which are arranged at intervals in the first direction are formed in the protective base. According to the protective base disclosed by the embodiment of the invention, the liquid cooling channel and the collision-resistant structure are combined, in the application process, the collision-resistant structure can effectively inhibit damage of external collision to the battery, and meanwhile, the cooling liquid is introduced into the liquid cooling channel so that heat generated by the battery pack can be absorbed in time.
本发明实施例公开了电池包用防护底座、电池包箱体、电芯直接集成电池包和车辆,电池包用防护底座包括:主体和耐撞结构,所述主体包括顶板、底板和侧板,所述顶板、所述底板和所述侧板共同围成第一容置空间;所述耐撞结构设置在所述第一容置空间内,所述耐撞结构包括沿第一方向交替排列并相互连接的多个第一耐撞子结构和多个第二耐撞子结构;所述防护底座形成有沿所述第一方向间隔排列的多个液冷通道。本发明实施例的防护底座将液冷通道与耐撞结构相结合,在应用过程中,耐撞结构能有效抑制外部撞击对电池的损害,同时,液冷通道中通冷却液能够及时吸收电池包所产生的热量。
