A damping member (100), a bottom bracket frame (40), a power battery box assembly and a battery swapping vehicle. The damping member (100) comprises a plate-shaped metal substrate layer (10), an elastic layer (20) formed on the metal substrate layer (10), and a wear-resistant layer (30) formed on the elastic layer (20), wherein the area of the metal substrate layer (10) is greater than the area of the elastic layer (20), the metal substrate layer (10) is provided with two or more through mounting holes (11), and the elastic layer (20) and the wear-resistant layer (30) avoid the mounting holes (11). The damping member (100) forms a multi-layer structure, realizes independent functions of each layer, can be organically and tightly combined into a whole, and has high bonding strength. The mounting area of the metal substrate layer (10) is large, the damping member (100) is mounted and fixed by using the metal substrate layer (10), a fastener (101) is prevented from being in direct press contact with the elastic
