Description

Technical Field

[0001] The present invention relates to a charger. Background Art

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

[0003] An example of a charger is an electric vehicle charger for charging a vehicle such as an electric vehicle. By connecting a charging connector provided at the end of a charging cable to a connection port provided in the electric vehicle, electric energy is supplied to the battery of the electric vehicle.

[0004] The charger includes a power module connected to a charging cable and a charger body having a space for accommodating the power module. In order to use the charging cable, the wound charging cable can be unwound and pulled out for use.

[0005] The charger may be provided with a locking device. An example of a charger provided with a locking device is the electric vehicle charging device disclosed in Korean Authorization Patent Announcement 10-1384613B1 (announced on April 11, 2014), which includes: a charger body for supplying power to the electric vehicle through a charging cable; a storage box for storing the charging cable arranged on the left or right side of the charger body; and a locking device provided for opening and closing the door of the storage box. If the locking device completes the payment of the charging demand amount through the user interface part and the card identification part provided on the charger body, it will be judged as an authenticated user and the door of the storage box will be opened. If it is recognized that the door is locked, the payment processing result is output and the door is locked. Summary of the Invention

[0006] Problems to be solved by the invention

[0007] This embodiment aims to provide a charger that can easily open and close the door without unlocking tools such as keys.

[0008] Means used to solve problems

[0009] According to the charger of this embodiment, it includes: a charger body, which forms a space; a door, which is used to open and close the space; a bracket; a wheel, which is rotatably arranged on the bracket and formed with a connecting rod; a driving source, which is used to rotate the wheel; a lever, which is formed with a long hole to guide the connecting rod and moves linearly through the wheel to lock or unlock the door; and a sensor, which is used to detect the lever.

[0010] The lever may be mounted on the bracket.

[0011] The bracket may be formed with a guide portion for guiding the lever to slide.

[0012] A guide rail extending along the longitudinal direction of the bracket may be formed on the guide portion.

[0013] The lever may be formed with a protrusion that is inserted into the guide rail.

[0014] The elongated hole may be perpendicular to the direction of movement of the lever.

[0015] The driving source may include: a motor; a motor cover covering the motor; and a worm rotated by the motor.

[0016] The motor may be a brushed motor that rotates the worm in one direction.

[0017] The wheel may be a worm wheel meshed with the worm. The worm wheel may include: a large diameter portion from which the connecting rod protrudes; and a small diameter portion protruding from the large diameter portion and having a gear meshed with the worm formed on its outer circumference.

[0018] The connecting rod can be closer to the center of the wheel and closer to the edge.

[0019] The sensor may include a photoelectric sensor, wherein the light emitting portion and the light receiving portion of the photoelectric sensor are separated from each other.

[0020] The lever may have a protruding body protruding therefrom.

[0021] If the lever is in the unlocked position, the protruding body is located between the light emitting portion and the light receiving portion.

[0022] If the lever is in the locked position, the protruding body is located outside the space between the light emitting portion and the light receiving portion.

[0023] The charger may further include: a display, which is arranged on at least one of the door or the charger body and is provided with an input interface.

[0024] The charger may further include: a communication module for communicating with a server.

[0025] The charger may also include a processor.

[0026] If door locking or door unlocking is input through the input interface, the processor may output a control signal to the motor.

[0027] If a door lock signal or a door unlock signal is received through the communication module, the processor may output a control signal to the motor.

[0028] Effects of the Invention

[0029] According to this embodiment, through the connecting rod formed on the wheel and the long hole formed on the lever, the motor can rotate in one direction to move the lever to the locking position and the unlocking position, thereby achieving locking or unlocking of the door with a simple structure and low cost.

[0030] In addition, administrators can lock or unlock the door through the display without using unlocking tools such as keys.

[0031] Additionally, administrators can lock or unlock the door remotely.

[0032] Furthermore, the lock is hidden by the door before it is opened, so the appearance of the charger can be more upscale. BRIEF DESCRIPTION OF THE DRAWINGS
