Integrated high-voltage battery case

摘要

The present invention relates to an integrated high-voltage battery housing. More particularly, it relates to an integrated high-voltage battery housing adapted to secure safety against side impact collisions while reducing the weight of a vehicle by integrating a connecting structure between a battery housing and a side member of a chassis of the vehicle. In particular, the integrated high-voltage battery housing includes: a bottom housing configured to receive a battery; a battery fixing bracket configured to fix the battery to a top surface of the bottom housing; and a plurality of flanges extending from an upper end edge of a side wall of the bottom housing and each having a coupling aperture for coupling the flange to a chassis side member. A protruding reinforcing portion extends transversely between opposite sides of the bottom housing on a bottom surface of the bottom housing.

1. An integrated high-voltage battery housing comprising:
a bottom housing configured to receive a battery; a battery fixing bracket configured to fix the battery to a top surface of the bottom housing; and a plurality of flanges extending from an upper end edge of a side wall of the bottom housing, each flange having a coupling aperture allowing the flange to be coupled to a chassis side member, wherein a protruding reinforcing portion extends transversely between opposite sides of the bottom housing on a bottom surface of the bottom housing, and is formed as a depression in the bottom surface of the bottom housing, wherein the battery fixing bracket has a bar-like shape that extends to opposite sides of the bottom housing and has an upwardly protruding protrusion, wherein the protrusion of the battery fixing bracket is disposed directly above the protrusion of the reinforcing portion, wherein the protrusion of the battery fixing bracket is overlapped with the protrusion of the reinforcing portion to form a space therebetween.
