  • the roof is provided with a plurality of rivet holes, and the rivets enter through the rivet holes and pass through the pre-embedded plate and the installation plate in turn.
  • the rivet holes are filled with sealant.
  • the roof and the embedded board are welded and fixed, and sealant is filled between the roof and the embedded board.
  • sealant is filled between the embedded board and the mounting board.
  • the present invention at least has the following beneficial effects:
  • the head of the bolt is welded and fixed with the head, so that the head of the bolt and the installation plate form a whole, and the part of the screw extending out of the roof is used to fix the battery pack.
  • the force of the screw transmits this tendency to the head, and the head, together with the mounting plate and the embedded plate, abut against the pre-embedded plate and release this force, thereby The strength of the bolted connection is preserved.
  • the mounting plate and the embedded plate since the contact area between the mounting plate and the embedded plate is large enough, even in the case of rapid acceleration or rapid deceleration of the car, that is, when the tendency of the battery pack to slip is large, the mounting plate and the embedded plate will abut against each other. The force that makes the battery pack slip can be removed, and the force on the mounting plate and the embedded plate per unit area is very small. Therefore, arranging the mounting plate and the pre-embedded plate can also protect the roof from deformation, prolong the service life of the roof, and at the same time enhance the safety of the roof battery pack.
