DETAILED DESCRIPTION

[0031] Referring to FIGS. 1-7, a charging system includes a charging housing 10 which may be located in a charging compartment 11 accessible via an opening 12 of a vehicle body component 14 (e.g., a body panel). The housing 10 defines an AC charging port socket 16, with associated pins located in pin openings 16a, and a DC charging port socket 18, with associated pins located in pin openings 18a. The DC charging port socket includes an associated charging port socket cover 20 that, in a closed position (per FIGS. 1-4) covers and protects the pins of the DC charging port socket 18, and that is movable to an access position (per FIG. 7) that uncovers the DC charging port socket 18 and enables a charging gun 22 to engage with the DC charging port socket 18. Intermediate positions of the charging port socket cover between the closed position the access position are shown in FIGS. 5-6.

[0032] Here, the charging port socket cover 20 includes a main cover plate 20a engageable over the DC charging port socket 18 when in the closed position, and an operating arm or arms 20b extending from the main cover plate 20a, with a pair of side pins 20c extending from the operating arm or arms 20b and ridable along a guide path defined by outwardly facing surfaces of respective side rails 22. An actuation device 30 includes an actuation plate component 30a that is mounted for pivotable movement about a horizontal pivot axis 32. The actuation device further includes an arm or arms 30b that extend from and pivot with the plate component 30a, and which are pivotably connected to a distal portion of the operating arm 20b such that the actuation device 30 and the cover 20 can pivot relative to each other about a horizontal pivot axis 34. Here, the pivot axis 32 is substantially parallel to the pivot axis 34.

[0033] As seen in the transitional progression of FIGS. 4-7, when the charging port gun 22 is moved toward the charging port socket 18, the gun engages with and rotates the actuation device 30 about the pivot axis 32, which causes the pivot axis 34 to shift downward and outwardly away from the charging port socket 18, thereby causing the cover 20 to shift downward and outwardly away from the charging port socket 18 (per FIG. 5). As the cover 20 shifts downward and away, the pins 20c slide along the guide path of surface(s) of the guide rail(s) 22. Further rotation/pivot of the actuation device 30 causes the cover 20 to move further downward and inward toward a final access position in which the cover 20 is beneath the actuation plate component 30a as the charging gun 22 engages into the charging port socket (per FIG. 7). A biasing assembly (e.g. in the form of a torsion spring along the connection axis 32 or a leaf spring assembly below/behind the actuation plate component) urges the actuation device into the set position of FIG. 3, which in turn urges the cover 20 into the closed position of FIG. 3, such that when the charging gun 22 is disengaged and removed, the actuation device 30 and the cover 20 automatically return to these positions.

[0034] FIGS. 9A-9C show an alternative embodiment in which the charging port socket cover 120 includes a pair of cover components 121 that are pivotable about respective pivot axes 124. The actuation device 130 is pivotable about horizontal axis 132. Here, the pivot axes 124 are not parallel with the pivot axis 132, and may, in embodiments, be substantially perpendicular to the pivot axis 132. As the actuation device 130 is pivoted about the axis 132 by engagement with the charging gun 122, the actuation device 130 causes the cover components 121 to pivot/rotate in opposite directions to clear the DC charging port socket, thus providing the access position of FIG. 9C. The connection between the actuation device 130 and the charging port socket cover components 121 for this purpose may be any of a geared connection and/or a cammed connection and/or a levered connection and/or a pivoting connection to translate movement of the actuation device into movement of the charging port socket cover. An optional connector guide 150 is also shown. Biasing is provided and may be any suitable configuration (e.g., torsion spring or leaf spring) to urge the actuation device 130 into its set position that corresponds to the closed position (FIG. 9A) of the cover components 121.

[0035] FIGS. 10A-10C show an alternative embodiment in which the charging port socket cover 220 includes a pair of cover components 221 that are pivotable about respective pivot axes 224. The actuation device 230 includes a pair of actuation structures/components 240 that are mounted for pivot/rotation about respective upright pivot axes 242. A geared connection 250 between each actuation component 240 and its corresponding cover component 221 is provided. The actuation structures/components 240 operate in the manner of swinging doors that are rotated in opposite directions when the charging gun is moved toward the charging port socket 18, thereby causing the cover components 221 to rotate in opposite directions to clear access to the charging port socket 18. Biasing is provided and may be any suitable configuration (e.g., a torsion spring associated with each actuation structure/component 240) to urge the actuation structures/components 240 into their set positions that correspond to the closed position (FIG. 10A) of the cover components 221.

[0036] Referring now to FIGS. 11-18, another embodiment of a charging system, similar that of FIGS. 1-7, is shown and includes a charging housing 310 which is located in a charging compartment 311 accessible via an opening 312 of a vehicle body component 314 (e.g., a body panel), where a compartment door or flap 313 is provided an movable between closed and open positions. The housing 310 defines an AC charging port socket 316, with associated pins located in pin openings 316a, and a DC charging port socket 318, with associated pins located in pin openings 318a. The DC charging port socket includes an associated charging port socket cover 320 that, in a closed position (per FIG. 11) covers and protects the pins of the DC charging port socket 318, and that is movable to an access position (per FIG. 12) that uncovers the DC charging port socket 318 and enables a charging gun 22 to engage with the DC charging port socket 318.

[0037] Here, the charging port socket cover 320 includes a main cover plate 320a engageable over the DC charging port socket 318 when in the closed position, and an operating arm or arms 320b extending from the main cover plate 320a, with a pair of side pins 320c extending from the operating arm or arms 320b and ridable along a guide path defined by outwardly facing surfaces of respective side rails 322. An actuation device 330 includes an actuation plate component 330a that is mounted for pivotable movement about a horizontal pivot axis 332. The actuation device further includes an arm or arms 330b that extend from and pivot with the plate component 330a, and which are pivotably connected to a distal portion of the operating arm 320b such that the actuation device 330 and the cover 320 can pivot relative to each other about a horizontal pivot axis 334. Here, the pivot axis 332 is substantially parallel to the pivot axis 334.

[0038] When the charging port gun 22 is moved toward the charging port socket 318, the gun engages with and rotates the actuation device 330 about the pivot axis 332, which causes the pivot axis 334 to shift downward and outwardly away from the charging port socket 318, thereby causing the cover 320 to shift downward and outwardly away from the charging port socket 318. As the cover 320 shifts downward and away, the pins 320c slide along the guide path of surface(s) of the guide rail(s) 322. Further rotation/pivot of the actuation device 330 causes the cover 320 to move further downward and inward toward a final access position in which the cover 320 is beneath the actuation plate component 330a as the charging gun 22 engages into the charging port socket. A biasing assembly (e.g. in the form of a torsion springs 330c along the connection axis 32 or a leaf spring assembly below/behind the actuation plate component) urges the actuation device into the set position of FIG. 11, which in turn urges the cover 320 into the closed position of FIG. 11, such that when the charging gun 322 is disengaged and removed, the actuation device 330 and the cover 320 automatically return to these positions.

[0039] It is to be clearly understood that the above description is intended by way of illustration and example only and is not intended to be taken by way of limitation. Still other variations and configurations are possible.
