So set up, in the actual installation, provide the support for power battery earlier with the frock, connect frame connection with battery connecting piece again and strengthen box and battery connecting piece bolted connection respectively at frame and power battery side, at last, will connect frame connection again and strengthen box and battery connecting piece bolted connection, nevertheless after removing the frock, power battery loses the support of frock, after the uneven road is gone for a long time, the bolt is elongated easily, produce the clearance between frame connection and strengthen box and the battery connecting piece, when the road surface is uneven, connect and strengthen box and battery connecting piece and rock the collision easily, twist the bolt this moment, reduce the frame connection and strengthen the clearance between box and the battery connecting piece, prevent to strengthen box and battery connecting piece and rock the collision.
Preferably, as a modification, the vertical holes are elongated, and the ends of the vertical holes extend to the edge of the first transverse plate away from one side of the frame. So set up, the bolt can be in vertical downthehole adjustment position to adapt to the power battery of different width.
Preferably, as a modification, the upper surface of the first cross plate is inclined toward the side close to the vehicle frame. So set up, the bolt can be constantly close to the frame at the screw up in-process to drive the second riser of power battery both sides and press from both sides power battery tight, and then prevent that the battery from rocking about.
