The invention discloses a transportation device for a new energy vehicle battery. The transportation device comprises a box body, sliding slots are formed in the centers of both sides of the inner cavity of the box body, and sliding bars are slidably connected to the inner cavities of the sliding slots. The inner sides of the sliding bars penetrate through the sliding slots and are fixedly connected with a placing box. A box cover is movably connected to the top of the left side of the placing box through a moving shaft, and a limiting rod is fixedly connected to the right side of the bottom of the box cover. Through the cooperation of the box body, the sliding slots, the sliding bars, the placing box, the box cover, the limiting rod, a first fixing block, a limiting slot, a first clampingslot, a first clamping rod, a fixing pin, supporting seats, fixing seats, buffer springs, buffer heads, pushing rods, shock absorbers, shock absorbing springs and a cover plate, the new energy vehicle battery can be subjected to shock absorption treatment, at the same time, the sealing performance of the transportation device is enhanced, the use effect of the transportation device is enhanced, the problem of poor use effect of an existing transportation device is solved, and the transportation device for the new energy vehicle battery is worth being promoted and used.
