The invention provides an anti-vibration device for a new energy electric vehicle battery, and relates to the technical field of new energy. The anti-vibration device for the new energy electric vehicle battery comprises a box, two first vibration-reduction devices, two clamping plates, a second vibration-reduction device, two clamp plates, a clamping block, a slot and a clamping device. Each first vibration-reduction device comprises a connecting block, a fixing plate, a fixed rod, a connecting plate, a sliding groove, a sliding plate, a notch, a protrusion, a trapezoidal block, an expansionspring, a pulling block, a movable rod, a through opening and a baffle, wherein the bottom of the connecting block is fixedly connected with the internal bottom of the box, the bottom of the fixing plate is fixedly connected with the top of the connecting block, and the bottom of the fixed rod is fixedly connected with the connecting block. By arranging the connecting plates, the sliding grooves,the sliding plates, the expansion springs, the pulling blocks, the movable rods, the through openings and the baffles, the anti-vibration device for the new energy electric vehicle battery solves theproblem that during vehicle driving, the battery easily collides with a battery box, so that the use of the battery is affected.
