A shaft assembly is arranged to connect two box bodies, so that the emergency power box may be of different structures to flexibly adapt to different installation scenarios; and a cavity is formed in the shaft assembly to allow connecting wires to penetrate through, so that a rotary structure is realized without exposing the internal connecting wires, and thus, the foldable emergency power box is safe and practical. ## Claims ### Claim 1 A foldable emergency power box with a shaft structure allowing wires to penetrate through, comprising a first box body for accommodating a main control circuit board and a second box body for accommodating a power supply, wherein the first box body and the second box body are rotatably connected through a shaft assembly, a cavity is formed in the shaft assembly, and wire holes communicated with the first box body and the second box body are formed in two sides of the cavity respectively; and an internal connecting wire connected to the power supply penetrates through the wire holes, stretches across the cavity in the shaft assembly and extends into the first box body to be electrically connected to the main control circuit board, and the main control circuit board is connected to an external emergency light through an external connecting wire. ### Claim 2 (depends on 1) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 1, wherein the shaft assembly is an 8-shaped shaft assembly having two ends provided with a first circular connecting portion and a second circular connecting portion respectively, the first circular connecting portion is rotatably connected to the first box body, the second circular connecting portion is rotatably connected to the second box body, and the wire holes are formed in a side, close to the first box body, of the first circular connecting portion and a side, close to the second box body, of the second circular connecting portion respectively. ### Claim 3 (depends on 2) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 2, wherein arc-shaped anti-skid grooves are formed along an edge of the first circular connecting portion and an edge of the second circular connecting portion respectively, multiple sliding teeth are disposed in each said arc-shaped anti-skid groove in parallel, and anti-skid blocks are disposed at positions, opposite to the arc-shaped anti-skid grooves, of the first box body and the second box body and extend into gaps between the sliding teeth. ### Claim 4 (depends on 2) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 2, wherein arc-shaped stop grooves are formed along an edge of the first circular connecting portion and an edge of the second circular connecting portion respectively, and stop pillars are disposed at positions, opposite to the arc-shaped stop grooves, of the first box body and the second box body and extend into the arc-shaped stop grooves. ### Claim 5 (depends on 4) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 4, wherein the arc-shaped anti-skid grooves and the arc-shaped stop grooves have a radian of 90°. ### Claim 6 (depends on 2) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 2, wherein a second installation portion is disposed on a recess, between the first circular connecting portion and the second circular connecting portion, of the shaft assembly, and a second bolt hole allowing a bolt to be inserted and installed therein is formed in the second installation portion. ### Claim 7 (depends on 1) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 1, wherein a power supply chamber is disposed in the second box body, and the power supply is installed in the power supply chamber; and a power installation hole is formed in an outer wall, opposite to the power supply chamber, of the second box body, and a power supply lid is disposed over the power installation hole. ### Claim 8 (depends on 1) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 1, wherein a power wire outlet is formed in an end, away from the shaft assembly, of the first box body, and the external connecting wire has an end electrically connected to the main control circuit board and an end stretching out via the power wire outlet. ### Claim 9 (depends on 1) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 1, wherein first installation portions extend from a side wall of the first box body and a side wall of the second box body, and first bolt holes allowing bolts to be inserted and installed therein are formed in the first installation portions. ### Claim 10 (depends on 8) The foldable emergency power box with a shaft structure allowing wires to penetrate through according to claim 8, wherein anti-skid portions are disposed on sides, away from the first installation portions, of the first box body and the second box body, and the anti-skid portions are located on edges of the first box body and the second box body and extend upwards to form anti-skid lines.
