It should be understood that the various embodiments of the present invention are different, but need not be mutually exclusive. For example, certain features, structures, and characteristics described herein may be implemented in other embodiments without departing from the spirit and scope of the invention in connection with an embodiment. It is also to be understood that the position or arrangement of the individual components within each disclosed embodiment may be varied without departing from the spirit and scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is to be limited only by the appended claims, along with the full scope of equivalents to which such claims are entitled, if properly explained. In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings in order that those skilled in the art can easily carry out the present invention.

FIG. 1 is a perspective view showing the outline of an electric vehicle charging apparatus installed on a pole according to an embodiment of the present invention.

1, an electric vehicle charging apparatus according to an embodiment of the present invention includes a main body 180, a holder 183, a charging cable 184, a charger 185, a cradle 186, and a cover 187 .

The main body 180 may be installed on the electric pole 10 to supply electric power to the electric vehicle. Here, the electric pole 10 is not limited to a pole, but means a pole capable of hanging the electric vehicle charging apparatus 100 and providing an environment for receiving electric energy from the electric distribution line and delivering it to the electric vehicle charging apparatus 100 .

For example, the main body 180 may receive power from a power cable 190 connected to a power distribution line, and may include the configuration of the electric vehicle charging apparatus shown in FIG. The main body 180 can supply electric power to the electric vehicle as the charger 185 is electrically connected to the electric vehicle.

For example, a cover 187 may be disposed on the main body 180. The cover 187 is controlled to be exposed to the outside of the main body 180 when the mounting space of the mount 186 is isolated from the outside of the main body 180 and is in the open state when the cover 187 is in the closed state . When the cover 187 is in the open state, the charger 185 can be electrically connected to the electric vehicle easily by the driver of the electric car. When the cover 187 is in the closed state, the charger 185 can be protected from an external impact or a negative environment, and the charger 185 can be prevented from being stolen.

The charging cable 184 may be configured to be electrically connected between the main body 180 and the charger 185 configured to be electrically connected to the electric vehicle and may be supported by the holder 183.

The charging cable 184 may extend from the body 180 prior to charging of the electric vehicle charging device and may be retracted to the body 180 after charging of the electric vehicle charging device.

If the extension length of the charging cable is always fixed, the charging cable can often come in contact with the floor or obstacles and can lead to damage or safety accidents. Ideally, the charging cable may be wound by the operator of the electric car, but the charging cable management by the electric car driver is usually limited.

The charging cable 184 may be wound on a reel at least a portion of which is disposed inside the body 180 and may be extended or retracted by rotation of the reel.

The electric vehicle charging apparatus according to an embodiment of the present invention can reduce the frequency of the floor or obstacle contact of the charging cable 184 by controlling the rotation or fixing of the reel. Thus, the safety of the charging cable 184 can be improved, and safety accidents caused by the charging cable 184 can be prevented.

For example, the rotation or fixation of the reel may be mechanically controlled by the force received by the holder 183 supporting the recharging cable 184. That is, the portion of the charging cable 184 supported by the holder 183 can be subjected to a force by the driver of the electric car holding and holding the charger 185 for charging. The reel connected to the holder 183 may protrude to the outside of the main body 180, and the state of the reel may be changed to a rotatable state while being fixed by the protrusion.

Further, the rotation or fixing of the reel can be controlled by a retractor to be described later with reference to Fig.

And the second port 120 may be configured to receive power from the power distribution line 20.

The blocking unit 130 may switch the open / close state between the first port 110 and the second port 120. [ The charging of the electric vehicle charging apparatus 100 with respect to the electric vehicle 300 may be determined according to the switching state of the blocking unit 130.

The control unit 140 may control the operation of the blocking unit 130 based on the information included in the signal received by the communication unit 150 or the charging request information input by the input unit 160. [

For example, when the load amount corresponding to the transformer load information received by the communication unit 150 is greater than the reference load amount, the controller 140 electrically connects the first port 110 and the second port 120 The blocking unit 130 can be controlled to be opened.

For example, the controller 140 determines the power supply voltage, the frequency, the DC / AC status, the wired / wireless mode, the charging mode, and / or the charging speed based on the charging request information input by the input unit 160 The switching point of the blocking unit 130 can be controlled, and charge information can be generated accordingly.

Depending on the design, the control unit 140 may control the state of the cover shown in Fig. For example, the controller 140 may close the cover when the charger is detected by the sensor 165.

The sensor 165 may sense whether the charger shown in FIG. For example, the sensor 165 may be embedded in a cradle or exposed to the outside of the cradle, and may detect whether a charger is present at a predetermined position through a magnetic or optical method.

The sensing result of the sensor 165 may be transmitted to the controller 140. The control unit 140 may generate a control signal for driving the retractor 181 according to the detection result of the sensor 165 and may transmit the control signal to the retractor 181.

The retractor 181 can control the rotation or fixing of the reel to which the charging cable shown in Fig. 1 is wound according to the control signal.

For example, the retractor 181 may control the rotation of the reel so that the reel winds the recharging cable after the recharger is seated in the mount.

The retractor 181 may control the rotation or the fixing of the reel according to the control result of the blocking unit 130 of the control unit 140.

For example, the retractor 181 may be configured such that when the breaker 130 is electrically connected between the first port 110 and the second port 120, The reel may be controlled so that the reel is unlocked when the first port 110 and the second port 120 are electrically opened.

The assembly structure may be connected to the electric pole 10 by connecting members 189a and 189b. Accordingly, the main body 180 can be fixed to the electric pole 10.

The reel 182 may include a portion disposed within the body 180 and a protruding portion protruding from the body 180. The portion of the reel 182 disposed inside the main body 180 may be configured so that the charging cable 184 is wound by rotation, and the fixing of the charging cable 184 may be determined according to the protruding length of the protruding portion.

When the charging cable 184 is subjected to the force by the driver of the electric car, the protruding length of the protruding portion can be prolonged. Accordingly, the portion of the reel 182 disposed inside the main body 180 can be changed to a rotatable state in a state in which it is fixed by the protrusion of the protrusion.

FIGS. 4A and 4B are diagrams illustrating the appearance of the electric vehicle charging apparatus installed on the pole of FIG. 3 when viewed from the pole to the body.
