To the back side of the plate body.The outer gusset of retaining ring in above scheme plays outside booster action.
The plate body mounting portion includes mounting plate, and the front of the mounting plate and the front for docking flange are concordant；
It draws to be equipped between the back side of the mounting plate and the back side of the plate body and outer gusset is installed, the outer gusset of the installation is also same
When connect with the outer wall of the docking flange and the outer wall of the cabinet retaining ring.
Running through on the mounting plate has mounting hole.
The front of the plate body is additionally provided with a circle shutter card slot around the plate body hollow-out parts.After shutter card slot is used for
Additional plate is quickly in place by the phase.
The cabinet retaining ring, retaining ring inner reinforced plate, docking flange, the outer gusset of retaining ring, mounting plate, the outer gusset of installation and the plate
The molding of body integrated die-casting.
The utility model has the advantages that using the electric automobile battery box plate of the utility model, whether it is connect with battery according to plate body, it will be electric
Pond boxboard is divided into part of the force and the part that do not stress, and only die casting is carried out to part of the force, thus frontal plane of projection when reducing die casting
Product, even if biggish battery case, it is possible to use the press die casting of small tonnage；And the hollow-out part not stressed can add outside the later period
Plate is closed.
