1. A battery module, comprising:
at least one battery unit array structure (10), each of the at least one battery unit array structure (10) comprising a plurality of battery units (11) and a plurality of busbars (12) electrically connected to the plurality of battery units (11);
an upper cover (13);
a lower cover (14), the at least one battery unit array structure (10) being disposed between the upper cover (13) and the lower cover (14); and
a fireproof component (17) disposed vertically and configured to block flame and high-temperature particles ejected from the vent (116),
wherein each of the plurality of battery units (11) in each of the at least one battery unit array structure (10) is provided with a vent (116) facing towards the fireproof component (17);
wherein the at least one battery unit array structure (10) comprises two or more battery unit array structures (10) comprising a first battery unit array structure (101) and a second battery unit array structure (102) adjacent to the first battery unit array structure (101);
wherein the fireproof component (17) comprises a fireproof main body (171) extending along a substantially vertical direction, and a first extension portion (172) connected to an upper end of the fireproof main body (171) and extending towards the first battery unit array structure (101), the fireproof component (17) further comprises a second extension portion (173) connected to the upper end of the fireproof main body (171) and extending towards the second battery unit array structure (102); and the first extension portion (172) and the second extension portion (173) are configured to prevent flame and high-temperature particles ejected from the vent (116) from ejecting upwards in a substantially vertical direction;
wherein the vent (116) of each of the plurality of battery units (11) of the first battery unit array structure (101) and the vent (116) of each of the plurality of battery units (11) of the second battery unit array structure (102) both face towards the fireproof main body (171), and the fireproof main body (171) is disposed between the vent (116) of each of the plurality of battery units (11) of the first battery unit array structure (101) and the vent (116) of each of the plurality of battery units (11) of the second battery unit array structure (102);
wherein the battery module further comprises a fire-extinguishing component (18), wherein the fire-extinguishing component (18) is provided below the lower cover (14), and the fire-extinguishing component (18) is provided with a fluid passageway for storing a fire-extinguishing liquid for extinguishing the flame and cool the high-temperature particles blocked by the fireproof component (17).
