Description

Charger The present invention relates to a charger. A charger is a device used to charge a battery. An example of a charger may be an electric vehicle charger for charging vehicles such as electric vehicles, and electrical energy is supplied to the battery of an electric vehicle by connecting a charging connector provided at the end of a charging cable to a connection inlet installed in the electric vehicle. The charger includes a power module to which a charging cable is connected, and a charger body that forms a space for accommodating the power module. The user can connect the charging cable to the vehicle after removing the connector (charging gun or plug) provided on the cable from the charger body. U.S. Patent Publication US 11,260,767 B2 (Patent dated May 1, 2022) discloses a cable retrieval system comprising a wire connected to a charging cable, and the cable retrieval system comprises an enclosure having an opening formed therein, a movable pulley movably accommodated in the enclosure, a movable counterweight fastened to the movable pulley, a ring fixed inside the enclosure, a pulley positioned around the opening of the enclosure, and a wire having one end fastened to the ring and the other end fastened to the cable, and lifting the movable pulley. FIG. 1 is a perspective view of a charger according to the present embodiment, FIG. 2 is a perspective view showing a wire device according to the present embodiment, FIG. 3 is a perspective view showing a pulley and a pulley bracket according to the present embodiment, FIG. 4 is a figure illustrating the process when a wire is gradually pulled according to the present embodiment. FIG. 5 is a perspective view showing a damper according to the present embodiment, FIG. 6 is a figure showing a plurality of dampers and a second weight according to the present embodiment. Specific embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of a charger according to the present embodiment, FIG. 2 is a perspective view showing a wire device according to the present embodiment, FIG. 3 is a perspective view showing a pulley and a pulley bracket according to the present embodiment, and FIG. 4 is a diagram showing the process when a wire according to the present embodiment is gradually pulled. The charger may include a charging cable (1), a cable cover (2), and a wire device (3). The charger may further include a power module (not shown) to which a charging cable (1) is in contact, and a charger body (11) that accommodates the power module. The charger body (11) can form the exterior of the charger. A space (S1) can be formed inside the charger body (11). One end of the charging cable (1) can be connected to a power module inside the charger body (11), and the other end of the charging cable (1) can have a connector (12, charging gun or plug) connected to a vehicle such as an electric vehicle. The charging cable (1) can pass through a cable penetration formed in the charger body (11) between one end and the other end. A connector holder (13) on which a connector (12) is mounted may be placed on the charger body (11). A display (14) that displays various information related to charging may be placed on the charger body (11). The cable cover (2) can be placed on the charging cable (1). The cable cover (2) can be placed between one end of the charging cable (1) and the connector (12). The cable cover (2) can be placed to wrap around a portion of the charging cable (1).
