Meanwhile, recently, technologies for arranging a charging door on the radiator grill side of a vehicle have been introduced in consideration of space efficiency and shape freedom of the vehicle.

For example, in the conventional charging door for a vehicle, the inlet of the charging port for charging the battery (hereinafter referred to as 'charging port') is disposed on the radiator grill side of the vehicle, and the charging door is configured to open and close the charging port.

The conventional charging door for a vehicle includes a single hinge in which the charging door body is provided inside the charging port, and a rotating body in the form of an arc-shaped link that rotates around the hinge and protrudes in front of the charging port.

When the charging door is opened, the rotating body rotates around the hinge and protrudes to the outside of the charging port, so that the charging door body protrudes long to the outside of the radiator grill after opening the charging port. Conversely, when the charging door is closed, the rotating body rotates around the hinge and protrudes to the inside of the charging port, so that the charging door body is pushed into the radiator grill and operated in the form of closing the charging port.

However, according to the structural restriction using the conventional single hinge and rotating body, in order to sufficiently open the charging port, the amount of displacement (this is referred to as the 'forward protrusion') of the charging door body and the rotating body protruding forward becomes too large. had no choice but to

In the end, as the amount of forward protrusion of the charging door became too large, it caused a collision with the user's body during charging, resulting in a risk of safety accidents, or there were problems of device breakage and vehicle damage due to collision and interference problems with the charging gun. .

As a prior document related to the present invention, there is Republic of Korea Patent Publication No. 10-1988633 (published on June 12, 2019), and the prior document discloses a charging port device for an electric vehicle.

The conventional charging port device for an electric vehicle disclosed in the prior literature has advantages such as easy door open identification and convenient door open confirmation. However, the conventional charging port device for an electric vehicle disclosed in the prior literature does not suggest a solution for reducing the forward protrusion amount of the door in the charging door having the door body in the form of a pivot link.

The charging port 20 is opened.

In the conventional vehicle charging door (1, see FIG. 2), a single rotating body (7, see FIG. 2) rotates in one direction based on a single hinge (5, see FIG. 2) and protrudes from the charging port. As a result, the charging door body 3 (see FIG. 2 ) protrudes forward to open the charging port 20 .

On the other hand, in the charging door 1000 for a vehicle according to an embodiment of the present invention, the charging door 1000 is rotated in the first direction R1 of the charging port 20 (eg, the front-rear direction or the horizontal direction, etc.). The shorter protruding primary opening operation is performed first.

Next, in the state in which the charging door 1000 is first opened, the secondary opening operation in which the charging door body 110 rotates in the second direction R2 (eg, up and down or vertical direction, etc.) is performed. Accordingly, the charging door 1000 for a vehicle according to an embodiment of the present invention can sufficiently open the charging port 20 while the amount of forward protrusion is reduced to half compared to the conventional charging door (see FIG. 1 and FIG. 2 ). have.

Hereinafter, a detailed configuration of the charging door 1000 for a vehicle according to an embodiment of the present invention will be described in detail.

3 to 5, the charging door 1000 for a vehicle according to an embodiment of the present invention includes a charging door body 100, a first charging door opening assembly 200, and a second charging door opening assembly ( 300) is included.

The charging door body 100 refers to a door body that opens and closes the charging port 20 of the vehicle. For example, the charging door body 100 may be provided in the form of a door that closes and seals the charging port 20 corresponding to the inlet of the charging port or opens and opens the charging port 20 when vehicle charging is required. .

The first charging door opening assembly 200 is a link that rotates the charging door body 100 from the charging port 20 in the first direction R1 to make the charging door body 100 move forward and backward of the radiator grill 11 . It may be a shape member. In other words, the first charging door opening assembly 200 primarily opens the charging port 20 by protruding and retracting the charging door body 100 in the first direction.

The charging door body 100 may rotate in the second direction R2 while in contact with the other end of the second connecting body 320 .

To this end, the second charging door opening assembly 300 may be configured to further include a rotation shaft protrusion 310 .

The rotation shaft protrusion 310 may have a shape protruding from the other end of the second connection body 320 toward the rear surface of the charging door body 100 by a predetermined length (see FIG. 4 ).

In addition, the rotation shaft protrusion 310 may be inserted into the insertion groove 140 when assembling between the charging door body 100 and the second charging door opening assembly 300 .

The insertion groove 140 may be provided on the rear surface of the charging door body 100 , and specifically, it may be located in the center of the rotation guide unit 130 provided in the rear protruding block 120 of the charging door body 100 . have.

In a state in which the rotation shaft protrusion 310 is inserted into the insertion groove 140 , the inserted position may be constrained to be arbitrarily separated and separated from the insertion groove 140 .

As configured in this way, the charging door body 100 protrudes from the charging port 20 in the first direction R1 by the first opening operation of the first charging door opening assembly 200 .

Subsequently, the charging door body 100 rotates in the second direction R2 with the rotation shaft protrusion 310 as the rotation center in a state protruding in the first direction R1 .

Accordingly, although the protrusion length of the charging door body 100 is reduced, the charging port 20 may be secondary opened, that is, completely opened by rotation in the second direction R2 .

Meanwhile, in the charging door 1000 for a vehicle according to an embodiment of the present invention, the charging door body 100 includes a door plate 110 and a rear protruding block 120 .
