Description

A canopy for charging an electric vehicle and an electric vehicle charging apparatus including the same

The present invention relates to a canopy for charging an electric vehicle and an electric vehicle charging device including the same, and more particularly, a charging cable that is heavy and thick and inflexible when charging an electric vehicle is easy to use for the charging port of an electric vehicle for general users as well as for those with weak traffic. The present invention relates to a canopy for charging an electric vehicle for general users and those with limited traffic, and an electric vehicle charging device including the same.

In recent years, as the seriousness of air pollution problems such as fine dust increases, the use of electric vehicles is encouraged and the number of users is increasing. Accordingly, the number of electric vehicle charging stations for charging electric vehicles is also increasing, and the need for electric vehicle charging devices installed in a small size in public institutions or home charging devices for charging electric vehicles at home is also increasing.

An electric vehicle charging device for charging an electric vehicle requires a power supply and a charging cable and a charging gun for charging the electric vehicle with electricity supplied from the power supply. When the user inserts the charging gun into the charging port of the electric vehicle, the charging cable should be handled without difficulty, but the charging cable for fast and super-fast charging lacks flexibility, which makes the user feel inconvenient when handling.

That is, in the case of a charging cable for rapid and super-quick charging, a high current needs to flow, so a high heat is generated due to a large amount of heat generated, so a flow path through which a refrigerant for cooling is flowed is additionally built into the charging cable. Therefore, in the case of fast and super fast charging cables, it is not easy to handle such as pulling or bending the charging cable for charging because it is not only thick but also has a lot of flexibility.

When the charging cable for fast and super fast is introduced in the existing charging device, the user must handle the charging cable according to the location of the charging port of the vehicle, but the fast and super fast charging cable is not easy to handle due to its characteristics. The discomfort is great. That is, the location of the charging port is different for each electric vehicle, and the user is inconvenient because the charging cable itself is thick and inflexible, making it difficult to handle. In particular, it is not easy to pull or bend the charging cable to insert the charging gun into the charging port in the case of the disabled, the elderly, and the vulnerable such as women.

Therefore, after moving the charging cable for fast and super-fast charging to the charging port location of the electric vehicle, even if the charging gun and charging port do not match, not only general users but also the disabled, the elderly, and women, etc. There is a need to develop a charging device that can easily adjust the location of the charging gun and the charging port by fine adjustment.

Republic of Korea Patent Publication No. 10-1883385 (2018. 07. 24.) Korean Patent Application Publication No. 10-2019-0062099 (2019. 06. 05.) Republic of Korea Patent Publication No. 10-2019-0042232 (2019. 04. 24.)

Accordingly, an object of the present invention was invented to solve the above problems, and it is possible to easily handle charging cables that are thick and heavy and inflexible when charging an electric vehicle, so that not only general users, but also people with disabilities, the elderly and women, etc. It is also to provide a canopy for charging an electric vehicle and a charging device for an electric vehicle including the same so that the electric vehicle can be conveniently charged.

In order to achieve the above-described object of the present invention, the electric vehicle charging canopy having a power supply unit for charging an electric vehicle, a charging gun provided, and a ceiling covering the upper side of the charging cable is mounted and transported. At least one or more traveling bodies, and a transfer rail installed under the canopy ceiling so that the at least one traveling body is horizontally transferred by an external force pulling the charging cable.

The transfer rail is at least one or more first rails installed so that the at least one or more traveling bodies are transferred from the upper side of the charging gun to the front where the electric vehicle is parked, and the at least one or more first rails are connected to a center portion, And a second rail installed in a'C' shape so that the at least one traveling body is transferred to the left and right by an external force pulling the charging cable.

Here, the at least one traveling body is a column-shaped transfer bar vertically installed to penetrate from the inside of the transfer rail to the lower outside through the open portion of the transfer rail, and the transfer bar to be accommodated inside the transfer rail. Is installed on the upper side of the ball receiving portion having a plurality of protrusions formed on the lower surface thereof, and is accommodated inside the ball receiving unit and is in contact with the inner bottom surface of the transfer rail through the plurality of protrusions and rotates while the transfer bar pulls the charging cable. It characterized in that it comprises a plurality of balls rotating so as to be transported according to an external force, and a cable connection portion to which the charging cable is mounted and connected to the lowermost end of the transport bar.

In addition, the traveling body may further include a balance wheel installed at the top of the transfer bar to adjust the horizontal balance during transfer of the transfer bar.

Meanwhile, the electric vehicle charging device including the canopy for charging the electric vehicle of the present invention includes a power supply unit for supplying DC power for charging an electric vehicle, and the DC power supplied from the power supply unit is supplied to the electric vehicle. A charging gun detachable from the charging port, a charging gun provided with the charging gun provided, a charging cable connected between the power supply unit and the charging gun to pass current, the power supply part, the charging gun provided, and the charging cable And a canopy having a ceiling covering the upper side of the canopy, a transfer rail installed on the ceiling of the canopy, and at least one traveling body horizontally transferred along the transfer rail by an external force pulling the charging cable.

According to the electric vehicle charging canopy of the present invention and the electric vehicle charging device including the same, the traveling body equipped with a thick and heavy charging cable is transferred along a transfer rail installed at the lower part of the canopy ceiling, so that the user needs to wind up or pull the charging cable with difficulty. You can easily insert the charging gun into the charging port of an electric vehicle without the need.

In addition, since the traveling body is transferred to the left or right of the parked electric vehicle through the transfer rail installed in a'C' shape, the user can easily move the charging gun by pulling the charging gun to the charging port position of the vehicle to be charged.

In addition, since the traveling body is provided with a transfer wheel or ball for transferring the charging cable, it is possible to reduce the resistance generated when the traveling body is transferred and contacts the transfer rail.

In addition, since the vehicle is equipped with a balance wheel, the transfer bar is tilted during transfer to reduce the resistance generated by contacting the transfer rail, so that not only general users but also the disabled, the elderly, and the weak traffic such as women can also charge cables. It is easy to charge the electric vehicle because it can be pulled easily.
