Abstract

A charge port door system can include a housing, a door configured to rotate between a cover position in which the door covers the housing and an uncover position in which the door uncovers the housing, and to move between a retracted position in which the door comes into contact with the housing and an advanced position in which the door is advanced from the housing in a state in which the door is in the cover position, a door actuator fixed to the door, and including an actuator member configured to linearly move and rotate by a motor, and a guide housing fixed to the housing, and configured to receive the actuator member, wherein the actuator member includes a first guide groove extending straightly along a longitudinal direction thereof, and a second guide groove extending spirally from the first guide groove.

First claim

What is claimed is:

1 . A charge port door system, comprising:
a housing; a door configured to rotate between a cover position in which the door covers the housing and an uncover position in which the door uncovers the housing, and to move between a retracted position in which the door comes into contact with the housing and an advanced position in which the door is advanced from the housing in a state in which the door is in the cover position; a door actuator fixed to the door, and including an actuator member configured to linearly move and rotate by a motor; and a guide housing fixed to the housing, and configured to receive the actuator member, wherein the actuator member comprises a first guide groove extending straightly along a longitudinal direction thereof, and a second guide groove extending spirally from the first guide groove, wherein the first guide groove and the second guide groove are provided in an outer surface of the actuator member, and wherein the guide housing includes a guide projection configured to be received in the first guide groove and the second guide groove.

2 . The charge port door system according to claim 1 , wherein the actuator member further comprises an attachment portion fixed to the door.

3 . The charge port door system according to claim 2 , wherein the attachment portion includes an attachment plate fixed to the door, and a plurality of bosses provided on edges of the attachment plate,
wherein each of the plurality of bosses has a hole defined in a center thereof, and wherein the plurality of bosses are fixed to the door by a plurality of fasteners.

4 . The charge port door system according to claim 3 , wherein the hole of at least one of the plurality of bosses has a slot shape.

5 . The charge port door system according to claim 1 , wherein the guide housing comprises:
a cylindrical portion; an attachment plate provided on the cylindrical portion; and a plurality of bosses provided on the attachment plate, wherein each of the plurality of bosses has a hole defined in a center thereof, and wherein the plurality of bosses are fixed to the housing by a plurality of fasteners.

6 . The charge port door system according to claim 5 , wherein the hole of at least one of the plurality of bosses has a slot shape.

7 . The charge port door system according to claim 1 , wherein the actuator member is configured to move between a first position, a second position, and a third position,
such that the door is in the retracted position in response to the actuator member being in the first position, such that the door is in the advanced position in response to the actuator member being in the second position, and such that the door is in the uncover position in response to the actuator member being in the third position.

8 . The charge port door system according to claim 7 , wherein, in response to the actuator member moving between the first position and the second position, the actuator member is guided to move linearly by the first guide groove and the guide projection, and
wherein, in response to the actuator member moving between the second position and the third position, the actuator member is guided to rotate around a central axis thereof by the second guide groove and the guide projection.

9 . The charge port door system according to claim 1 , wherein the door actuator further includes an actuator housing receiving the motor, and a guide sleeve extending from the actuator housing toward the door,
wherein the guide sleeve is received in the guide housing, and wherein the actuator member is movably received in the guide sleeve.

10 . The charge port door system according to claim 9 , wherein the outer surface of the actuator member is configured to match an inner surface of the guide sleeve.

11 . The charge port door system according to claim 1 , wherein the door actuator further includes a lead screw configured to be rotated by the motor,
wherein the lead screw has an external thread on an outer peripheral surface thereof, and wherein the actuator member has an internal thread meshing with the external thread of the lead screw.

12 . The charge port door system according to claim 11 , wherein the door actuator further includes a transmission mechanism configured to transmit a torque of the motor to the lead screw.

13 . The charge port door system according to claim 12 , wherein the door actuator further includes an operating gear configured to transmit the torque from the transmission mechanism to the lead screw.

14 . The charge port door system according to claim 13 , wherein the operating gear is fixed to the lead screw.

15 . A charge port door system, comprising:
a housing; a guide housing fixed to the housing, wherein the guide housing includes a guide projection; a door configured to cover a portion of the housing; and a door actuator fixed to the door, wherein the door actuator comprises:
an electric motor,
an actuator member configured to linearly move and rotate by the electric motor,
wherein the guide housing is configured to receive the actuator member therein,
wherein the actuator member comprises a first guide groove extending straightly along a longitudinal direction thereof, and a second guide groove extending spirally from the first guide groove,
wherein the first guide groove and the second guide groove are provided in an outer surface of the actuator member,
wherein the guide projection is configured to be received in the first guide groove and the second guide groove, and
wherein the actuator member includes an internal threaded portion therein,

a lead screw including an external threaded portion on an outer peripheral surface thereof, wherein the lead screw is rotatably coupled to the electric motor and configured to be rotated by the electric motor, wherein the internal threaded portion of the actuator member meshes with and threadedly engages with the external threaded portion of the lead screw,
wherein the charge port door system is configured such that rotation of the lead screw by the electric motor can cause an actuator-member motion of the actuator member, whereby the actuator-member motion of the actuator member can drive a door motion of the door, whereby the door can move between a first retracted cover position, a second partially-outwardly-extended cover position, and a third rotated-outwardly-extended uncover position, wherein the housing is covered and sealed by the door in the first retracted cover position of the door, and wherein the housing is exposed and accessible in the third rotated-outwardly-extended uncover position of the door, and wherein the door is pivoted relative to the housing in the third rotated-outwardly-extended uncover position.

16 . The charge port door system according to claim 15 , wherein the actuator member further comprises an attachment portion fixed to the door, wherein the attachment portion includes an attachment plate fixed to the door, and a plurality of bosses provided on edges of the attachment plate,
wherein each of the plurality of bosses has a hole defined in a center thereof, and wherein the plurality of bosses are fixed to the door by a plurality of fasteners.

17 . The charge port door system according to claim 16 , wherein the hole of at least one of the plurality of bosses has a slot shape.

18 . The charge port door system according to claim 15 , wherein the guide housing comprises:
a cylindrical portion; an attachment plate provided on the cylindrical port
