Description

Charging door device

[0001] The present invention relates to a charging door device. In particular, the present invention relates to a charging door device that adjusts the pressure applied to the charging door through an operating force compensation module mounted on a vehicle.

[0002] Looking at the process of opening and closing the charging door for charging, when the compression force of the rubber damper placed in the housing reaches a certain level due to the pressing action applied to the charging door, the charging switch mounted on the outer panel of the housing can be pressed.

[0003] Meanwhile, the compression force of the rubber damper shows a change of approximately 1 kgf per 0.1 mm of compression, so there is a difficulty in managing the tolerance variation through the structure from the external panel to the charging switch unit to within 0.2 mm.

[0004] Additionally, mass production is difficult due to factors such as changes in the compression force of the rubber damper depending on temperature. Furthermore, changes in operating force occur due to changes in the gap between the charging door and the switch caused by thermal deformation of the external panel resulting from changes in the compression force of the rubber damper.

[0005] The present invention aims to solve the above-mentioned problems and other problems.

[0006] Another object of the present invention is to provide a charging door device characterized in that a link connecting member hingedly connected to a housing portion is arranged, and a pressing force on a charging door panel connected to the link connecting member is corrected through an operating force correction module arranged in the housing portion.

[0115] The chamber cover (430) may include a cover engaging protrusion (435). The cover engaging protrusion (435) may be formed to protrude from the inner surface of the cover body (431) based on the elastic body securing protrusion (433).

[0116]

[0117] Below, referring to FIG. 10 and FIG. 11, the relationship between the chamber cover (430) and the compensation chamber (130) is shown.

[0118] The compensation chamber (130) may be formed on the outer surface of the upper port housing portion (125). For example, the compensation chamber (130) may be formed on the upper front portion (125t) of the upper port housing portion (125).

[0119] The compensation chamber (130) may include a compensation chamber body (131). The compensation chamber body (131) may be formed on the upper front portion (125t) of the upper port housing portion (125). The compensation chamber body (131) may extend from the outer surface of the port housing portion (120). For example, the compensation chamber body (131) may extend from the outer surface of the upper port housing portion (125).

[0120] The compensation chamber (130) may include a compensation chamber core (132). The compensation chamber core (132) may form a central portion of the outer surface of the compensation chamber body (131). The compensation chamber core (132) may form a hollow portion connected to the chamber inlet (133). The compensation chamber core (132) may have a hollow cylindrical shape.

[0121] The compensation chamber (130) may include a chamber inlet (133). The chamber inlet (133) may form an outer opening of the compensation chamber core (132).

[0122] The compensation chamber (130) may include a protrusion coupling member (135). The protrusion coupling member (135) may be formed on both sides of the compensation chamber body (131) with the compensation chamber core (132) as the center. The elastic body mounting protrusion (433) may correspond to the chamber inlet (133), and the cover coupling protrusion (435) may correspond to the protrusion coupling member (135). Meanwhile, the cover body (431) may be coupled to the outer surface of the compensation chamber body (131) with the compensation chamber core (132) as the center.

[0123] The link connecting member (300) is connected to a hinge pin (101) that is rotatably inserted into a hinge pin connecting hole (125h). The link connecting member (300) can rotate around a link rotating member (301) connected to the hinge pin (101). The link connecting member (300) can receive a pressing force from the charging door panel (200) through the link connecting end (303). The link connecting member (300) can provide a pressing force to the operating force compensation module (400) through the link pressing end (320).

[0124] A first pressing force may be applied to the charging door panel (200) from outside the vehicle by a user. The first pressing force applied to the charging door panel (200) may be redirected by a link connecting member (300). The pressing force transmitted by the link connecting member (300) may be transmitted to an operating force correction module (400). The pressing force transmitted to the operating force correction module (400) may be a second pressing force.

[0125] For example, the direction of the first pressing force and the direction of the second pressing force may be directed in different directions. For example, the direction of the first pressing force and the direction of the second pressing force may be directed in opposite directions through the link connecting member (300).

[0126] For example, referring to FIG. 5, when the charging door panel (200) is pressed toward the inside of the vehicle, the link connecting member (300) can be rotated counterclockwise around the link pivot (301). Accordingly, the link pressing end (320) of the link connecting member (300) can press the plunger (410) of the operating force correction module (400) disposed in the correction chamber (130) toward the outside of the vehicle.

[0127] Meanwhile, the tolerance for operating force management through the operating force compensation module (400) may be 3.75±0.25 kgf. The pressure applied to the operating force compensation module (400) may be in the range of 3.5 kgf to 4.0 kgf.

[0128] It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit and essential characteristics thereof. The above detailed description should not be construed in any way as limiting but rather as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the scope of equivalents of the present invention are intended to be included within the scope of the present invention.
