Aluminum alloy battery pack shell and manufacturing method thereof

The invention discloses an aluminum alloy battery pack shell and a manufacturing method thereof. The aluminum alloy battery pack shell comprises an upper cover body and a lower shell body. A sealing strip is arranged between the upper cover body and the lower shell body, and a space used for mounting a battery module is formed; both the upper cover body and the lower shell body are formed throughcombination of aluminum alloy plates; the aluminum alloy plates comprise upper face layers, lower face layers, middle honeycomb core layers and first high temperature resistant inorganic glue layers,and further comprises reinforcing layers arranged between the middle honeycomb core layers and the first high temperature resistant inorganic glue layers, and blocking structures connected to the honeycomb-shaped holes of the middle honeycomb core layers. The aluminum alloy battery pack shell adopts the aluminum alloy plates provided with the reinforcing layers and the blocking structures, the strength of the plate structu
