The housing 110 is installed to be fixed to the ground, and a mounting space 100 in which a charger 170 connected to a cable (c) for supplying current to the forklift can be mounted can be formed inside the housing 110. Accordingly, the housing 110 may be formed in a size capable of accommodating a plurality of chargers 170 . The housing 110 may be formed of a hard material such as steel to protect the charger 170 therein. The housing 110 is formed to have a predetermined width and length, and a plurality of chargers 170 may be mounted therein. That is, the housing 110 may be formed with a width and length capable of accommodating the plurality of chargers 170 therein. For example, the housing 110 may be formed in a box shape having a predetermined width and length. The housing 110 is formed such that the front side is open, and the front side may be shielded by the door 120 .

The door 120 is installed on the front of the housing 110 to open and close the mounting space 100 inside the housing 110 .

A viewing window 121 may be formed in the door 120 . The viewing window 121 may be formed at each position corresponding to each mounting space 100 so that the plurality of mounting spaces 100 formed inside the housing 110 can be checked.

The separation frame 130 is installed inside the housing 110 to separate the mounting space 100 into a plurality of pieces. Specifically, one or more separation frames 130 may be installed along the vertical height inside the housing 110 . For example, when one separation frame 130 is installed at the center along the vertical height inside the housing 110, the inside of the housing 110 has an upper mounting space 100 and a lower mounting space 100. The mounting space 100 can be separated into two.

Here, referring to FIG. 2 , two separation frames 130 may be installed spaced apart from each other along the upper and lower heights inside the housing 110 .

The ventilator 140 is installed on the rear side of the housing 110 to circulate air in the mounting space 100 . Specifically, the ventilator 140 may discharge heat and air within the mounting space 100 to the outside. As heat and air inside the housing 110 are circulated with external air by the fan 140, the temperature of the charger 170 can be lowered and problems such as fire occurrence can be reduced.

The fire detection unit 150 is installed in the mounting space 100 inside the housing 110 and detects whether or not there is a fire by detecting smoke or temperature inside the housing 110 . When a fire is detected by the fire detection unit 150, a manager or a nearby worker is notified of whether a fire has occurred through an alarm sound, etc., and the fire can be quickly extinguished to prevent a large fire from occurring.

The display unit 160 may be installed outside the door 120 . The display unit 160 is installed adjacent to each viewing window 121 on the outside of the door 120 to display a charging state and a fully charged state of each of the plurality of chargers 170 .

Referring to FIGS. 4 and 5 , six mounting spaces 100 are formed inside the housing 110 to mount six chargers 170 therein. A plurality of separation frames 130 inside the housing 110 may separate internal spaces so that six mounting spaces 100 are formed inside the housing 110 .

First, referring to FIG. 4, when the left and right widths of the housing 110 are formed to a width in which two chargers 170 can be mounted, the separation frame 130 is installed perpendicularly to the ground at the center along the left and right directions of the housing 110 to separate the space inside the housing 110 into left and right sides. The separation frames 130 are spaced apart from each other along the upper and lower heights of the housing 110 in each of the left and right spaces, so that three mounting spaces 100 may be formed on each of the left and right sides. Accordingly, six mounting spaces 100 are formed inside the housing 110 so that six chargers 170 can be installed.

Referring to FIG. 5 , when the vertical length of the housing 110 is formed long, four separation frames 130 may be spaced apart from each other inside the housing 110 along vertical heights. Accordingly, the mounting space 100 inside the housing 110 may be divided into five. A charger 170 may be installed in each mounting space 100 . Although not shown in the drawings, similarly, five separate frames 130 may be spaced apart along the vertical height to form six mounting spaces 100 .

6 is a diagram showing the distribution box 20 connected to the distribution box 10 according to FIG. 2, FIG. 7 is a view showing the configuration of the distribution box 20, and FIG. 8 is the distribution box according to FIG.

6 to 8 , the distribution box 20 may supply current to the charger 170 mounted in the distribution box 10 .

Here, the case of FIG. 6 shows the distribution box 20 when three chargers 170 are installed as shown in FIG. 2, and the case of FIG. 8 shows the distribution box 20 when six chargers 170 are installed as shown in FIG.

The distribution box 20 may include a main connection unit 210 , a current supply unit 220 , an earth leakage blocker 230 and an overcurrent blocker 240 .

The main connection unit 210 may receive current from the outside. For example, the main connection unit 210 may be connected to a power system that supplies current to a building and receive current.

The main connection unit 210 may include a main electrical lead-in unit 211 and a main blocking unit 212 . The main electrical inlet 211 may be connected to a power system that supplies current to the building and receive current from the outside.

The main blocking unit 212 may block current supplied from the outside. Alternatively, all of the current supply unit 220, the earth leakage blocking unit 230, and the overcurrent blocking unit 240 may be blocked to receive or supply current.

The current supply unit 220 is connected to the main connection unit 210 and is connected to one or more chargers 170 to supply current to each charger 170 . It is connected to the current inlet 171 of the charger 170 and can supply current to the charger 170 . Specifically, current supplied from the outside through the main electrical inlet 211 may be supplied to the charger 170 through the current supply unit 220 .

The earth leakage blocking unit 230 may be connected to one or more chargers 170 and cut off the supply of current to the charger 170 when detecting that current supplied to each charger 170 is shorted.

The earth leakage blocking unit 230 may include an anomaly detection unit 231 , a primary blocking unit 232 and a secondary blocking unit 233 .

The earth leakage blocking unit 230 may be installed to correspond to each charger 170 . For example, when three chargers 170 are installed in the housing 110, three earth leakage blocking units 230 may also be installed and connected to each charger 170.

The abnormality detection unit 231 may detect an abnormality in the cable (c) supplying current to each charger 170 . For example, the anomaly detection unit 231 may detect a case in which a current leakage occurs due to a problem such as disconnection of the cable c.

When an abnormality is detected by the abnormality detection unit 231, the primary blocking unit 232 may cut off the supply of current to the charger 170 in which the abnormality is detected.

In a state where an abnormality is detected by the abnormality detection unit 231, the secondary blocking unit 233 does not block the supply of current to the charger 170 in which the abnormality is detected by the primary blocking unit 232. When current is continuously supplied to the charger 170, the current supply to the charger 170 in which the abnormality is detected may be cut off.

For example, when an abnormality is detected in the earth leakage blocking unit 230 connected to any one charger 170 among the plurality of chargers 170, the primary blocking unit 232 connected to the corresponding charger 170 may be operated. However, when current is continuously supplied to the charger 170 in which the abnormality is detected by the abnormality detector 231 due to a malfunction of the primary blocker 232, the secondary blocker 233 detects the abnormality. Current supply to the charger 170 can be stopped.

The overcurrent blocking unit 240 may be connected to one or more chargers 170 and cut off current supply to the charger 170 when the current supplied to each charger 170 reaches a predetermined value.

The overcurrent blocking unit 240 may include a measuring unit 241 and a current blocking unit 242 .

The measurement unit 241 may measure the current supplied to each charger 170 .

The current cutoff unit 242 generates an overvoltage for a predetermined time in the cable (c) through which current is supplied to each charger 170, or when the amount of current supplied to each charger 170 reaches a predetermined value, the current supply to the charger 170 can be cut off.

For example, when an overvoltage occurs in a cable (c) through which current is supplied to each charger 170 for a predetermined time, the current cutoff unit 242 may block current supply to the charger 170 to prevent an accident such as a fire due to the overvoltage.

In addition, the current cutoff unit 242 may cut off the supply of current to the charger 170 when the amount of current supplied to each charger 170 measured by the meter reaches a preset value. For example, the amount of current supplied to the forklift battery may be measured by measuring the amount of current from the time point when the charger 170 starts to supply current to the forklift battery. Accordingly, when the supplied amount of current reaches a predetermined value, it is determined that the battery is fully charged and current supply may be stopped.

At this time, the display unit 160 may be displayed in a fully charged state. Although not shown in the drawing, operations of the earth leakage blocking unit 230, the overcurrent blocking unit 240, and the display unit 160 may be controlled by a control unit.
