Description

charger

[0001] The present invention relates to a charger.

[0002] A charger is a device used to charge a battery.

[0003] An example of a charger may be an electric vehicle charger that charges a vehicle such as an electric vehicle, and electrical energy is supplied to the battery of the electric vehicle by connecting a charging connector provided at the end of a charging cable to a connection inlet installed in the electric vehicle.

[0004] The charger includes a power module to which a charging cable is connected and a charger body that forms a space for accommodating the power module. To use the charging cable, the coiled charging cable can be unwound and then pulled out.

[0005] A locking device may be installed in the charger, and an example of a charger having a locking device is an electric vehicle charging device disclosed in Korean Patent Publication No. 10-1384613 B1 (published on April 11, 2014), including: a charger body that supplies power to an electric vehicle through a charging cable; a storage box for storing the charging cable installed on the left or right side of the charger body; and a locking device installed for opening and closing the door of the storage box; wherein, when payment for the charging amount is made through a user interface unit and a card recognition unit provided in the charger body, the locking device determines that the user is an authenticated user and opens the door of the storage box, and when the door is recognized as being locked, outputs a payment processing result and locks the door at the same time.

[0006] The present embodiment provides a charger that can easily open and close a door without an unlocking tool such as a key.

[0007] A charger according to the present embodiment includes a charger body having a space formed therein; a door for opening and closing the space; a bracket; a wheel rotatably disposed on the bracket and having a connecting rod formed therein; a driving source for rotating the wheel; a lever having a hole formed therein through which the connecting rod is guided and linearly moved by the wheel and locked or unlocked to the door; and a sensor for sensing the lever.

[0008] The lever can be mounted on a bracket.

[0009] The bracket may be formed with a guide portion that guides the lever to slide.

[0010] A long guide rail can be formed in the length direction of the bracket in the guide section.

[0011] The lever may be formed with a protrusion inserted into the guide rail.

[0012] The direction of movement of the lever can be perpendicular to the direction of movement of the lever.

[0013] The driving source may include a motor; a motor cover covering the motor; and a worm gear rotated by the motor.

[0014] The motor may be a brushed motor that rotates the worm gear in one direction.

[0015] The wheel may be a worm wheel having a worm gear engaged therewith. The worm wheel may include a large diameter portion from which a connecting rod protrudes; and a small diameter portion having a gear formed on the outer periphery thereof that protrudes from the large diameter portion and on which a worm gear is engaged therewith.

[0016] The connecting rod can be closer to the rim than the center of the wheel.

[0017] The sensor may include a photo sensor in which a light emitting portion and a light receiving portion are spaced apart from each other.

[0018] The lever may have a protruding body.

[0019] When the lever is in the unlocked position, the protruding body can be positioned between the light emitter and the light receiver.

[0020] When the lever is in the locking position, the protruding body can be positioned anywhere other than between the light emitter and the light receiver.

[0021] The charger may further include a display disposed on at least one of the door or the charger body and having an input interface disposed thereon.

[0022] The charger may further include a communication module for communicating with the server.

[0023] The charger may further include a processor.

[0024] When the locking or unlocking of the door is input through the input interface, the processor can output a control signal to the motor.

[0025] When a signal for door locking or unlocking is received through the communication module, the processor can output a control signal to the motor.

[0026] According to this embodiment, the motor can be rotated in one direction by a connecting rod formed in the wheel and a hole formed in the lever to move the lever to a locking position and an unlocking position, and the door can be locked or unlocked with a simple structure and low cost.

[0027] Additionally, the administrator can lock or unlock the door through the display without an unlocking tool such as a key.

[0028] Additionally, the administrator can remotely lock or unlock the door.

[0029] Additionally, the locker is concealed by the door before the door is opened, which can enhance the charger's appearance.
