Charge port door
A door for a charging port of a vehicle includes a switch that transmits a control signal, a housing rim that is fixed to the vehicle and accommodates the switch, a door panel configured to open or close the housing rim based on the control signal, a spring that applies a pushing force to the door panel with respect to the housing rim, and a spring cover configured to be seated on the housing rim, accommodating the spring. When the door panel is moved toward the housing rim by an external pressure, the switch is operated.
1 . A charging port door assembly, comprising:
a housing rim configured to be fixed to a vehicle;
a switch disposed in the housing rim, wherein the switch transmits a control signal when pressed;
a door panel configured to open or close the housing rim based on the control signal;
a spring cover coupled to the door panel and exposed toward the housing rim;
a trigger coupled to the spring cover and configured to move relative to the spring cover; and
a spring coupled between the trigger and the spring cover to bias the trigger in a direction away from the housing rim,
wherein, in response to an external pressure being applied to the door panel, the door panel causes the trigger to protrude out with respect to the spring cover toward the housing rim, with the spring cover being seated on the housing rim, and causes the switch to be pressed.
2 . The charging port door assembly of claim 1 , wherein the spring cover and the trigger are engaged to restrict a movement range of the door panel.
3 . The charging port door assembly of claim 1 , wherein the housing rim comprises:
an upper housing rim disposed toward the door panel; and
a lower housing rim coupled to the upper housing rim to provide an accommodation space for the switch,
wherein the upper housing rim includes a housing aperture to allow movement of a stud provided in the trigger therethrough.
4 . The charging port door assembly of claim 3 , further comprising:
a sealing member made of a material deformable by a pressure applied via the stud, wherein the sealing member seals the housing aperture.
5 . The charging port door assembly of claim 4 , wherein the spring cover is seated on a seating surface formed by the upper housing rim and the sealing member.
6 . The charging port door assembly of claim 5 , wherein a surface of the sealing member and a surface of the upper housing rim are disposed on a same virtual surface, and
wherein the seating surface includes a portion of the virtual surface including the surface of the sealing member.
7 . The charging port door assembly of claim 4 , further comprising:
a pressure delivering member disposed between the sealing member and the switch to transmit the pressure from the stud to the switch.
8 . The charging port door assembly of claim 1 , wherein the door panel comprises:
an outer panel for receiving the external pressure; and
an inner panel disposed toward the housing rim and coupled to the outer panel,
wherein the spring cover is movable with respect to the inner panel.
9 . The charging port door assembly of claim 8 , wherein a stud included in the trigger provided on the outer panel presses the switch in response to the outer panel and the inner panel moving with respect to the spring cover by the external pressure.
10 . The charging port door assembly of claim 1 , wherein the switch transmits an open signal and a close signal alternatingly each time the switch is operated.
