Description

charger

[0001] The present invention relates to a charger.

[0002] A charger is a device used to charge a battery.

[0003] An example of a charger may be an electric vehicle charger that charges a vehicle such as an electric vehicle, and electrical energy is supplied to the battery of the electric vehicle by connecting a charging coupler provided at the end of a charging cable to a connection inlet installed in the electric vehicle.

[0004] To use the charging cable, unwind the coiled charging cable and then pull it out. However, due to its length, the middle part of the pulled-out charging cable may touch the floor. The part that touches the floor may be damaged, such as worn out, through repeated use, and may become contaminated by contaminants on the floor.

[0005] An example of a charger is a charging device for an electric vehicle disclosed in Korean Patent Laid-Open Publication No. 10-2021-0026907A (published on March 10, 2021), which includes: a charging body; a charging cable connected to the charging body and having a charging gun provided at an end; a guide frame installed on one side of the charging body and having a rail guide formed thereon; first and second roller modules formed to be capable of traveling along the rail guide of the guide frame; and a mounting bracket connected to the first and second roller modules and transported together, and on which the charging cable is mounted; wherein the first and second roller modules are capable of traveling on the rail guide according to the stopping position of the electric vehicle requiring charging, thereby moving the position of the charging cable.

[0006] Another example of a charger is a charging facility for an electric vehicle disclosed in Korean Patent Laid-Open Publication No. 10-2019-0091673A (published on August 7, 2019), which includes: a cable guide installed on the ceiling of a car deck on which an electric vehicle is loaded; a vehicle charging device that charges a driving battery of the electric vehicle while moving back and forth along the cable guide; and a power management device that supplies power to the driving battery, wherein the cable guide provides a path along which the driving unit of the vehicle charging device moves, and includes a rail installed on the ceiling in the longitudinal direction of the car deck on which the electric vehicles are arranged in a straight line; and a plurality of guide rings that are installed so as to be slidable along the rail and are configured so that a charging cable of the vehicle charging device can be hung at a predetermined interval, wherein the vehicle charging device includes: a charging cable having one end connected to the power management device and the other end provided with a plug, which charges the driving battery; And it includes a driving part that is installed so as to be drivable on the cable guide part and moves the charging cable.

[0007] The present embodiment provides a charger capable of minimizing tangling of a charging cable.

[0008] A charger according to the present embodiment may include a rail body having a plurality of rails formed thereon; a plurality of guides arranged to slide on each of the plurality of rails and on which a charging cable is mounted; and a spacer spaced apart from the plurality of guides.

[0009] The spacer may include a plurality of spacer guides guiding different portions of the charging cable and a bridge connecting the plurality of spacer guides.

[0010] The plurality of spacer guides include a lower spacer guide that guides the lower portion of the charging cable; and an upper spacer guide that guides the portion between the lower portion of the charging cable and the mounting portion mounted on the guide.

[0011] Upper spacer guides may be supplied in pairs.

[0012] The bridge may include a first bridge connected to a pair of upper spacer guides to space the pair of upper spacer guides apart, and a second bridge connected to the first bridge and the lower spacer guide to space the first bridge and the lower spacer guide apart.

[0013] Each of the plurality of guides may include a base; and a supporter formed on the bottom surface of the base and on which a charging cable is mounted.

[0014] Each of the plurality of guides may include an overlapping region that overlaps and hangs on an adjacent guide in the length direction of the guide, and a non-overlapping region that does not overlap with an adjacent guide in the length direction of the guide.

[0015] An overlapping area is formed at the base, and the supporters of multiple guides may not overlap.

[0016] Each of the plurality of guides may have a supporter formed with an opening that is open in a horizontal direction.

[0017] The opening directions of adjacent guides may be opposite to each other.

[0018] The direction of movement of the guide and the opening direction of the aperture can be orthogonal.

[0019] The first distance between the supports of adjacent guides in the longitudinal direction of the rail body may be longer than the second distance between the centers of the supports of adjacent guides in a direction orthogonal to the longitudinal direction of the rail body.

[0020] The supporters may not be aligned with the sides of the base.

[0021] The plurality of rails can be spaced apart in a direction perpendicular to the longitudinal direction of the rail body.

[0022] The rail body may include a body portion positioned between a pair of adjacent rails.

[0023] The body section can be gradually expanded from one end of the rail body to the other.

[0024] The charger may further include a body to which a charging cable is connected.

[0025] First of all, it can be closer to the main body than the other end.

[0026] According to this embodiment, the shape of the charging cable can be maintained while the spacer is spaced apart, and abrupt bending of the charging cable can be minimized.

[0027] In addition, each of the plurality of guides can sequentially move in the order in which the plurality of guides are arranged on the rail body, including an overlapping area and a non-overlapping area, and tangling of the charging cable can be minimized.

[0028] Additionally, since an overlapping area is formed at the base of each of the plurality of guides and the supporters of each of the plurality of guides do not overlap, tangling of the charging cable can be minimized.

[0029] In addition, since the moving direction of the guide and the opening direction of the opening are orthogonal, the moving direction of the guide and the winding direction of the charging cable can be aligned, and the user can move the charging cable by applying less force in the direction of moving the charging cable.

[0030] Additionally, since the supporter is not parallel to the side of the base, the overlap of the charging cable (3) can be minimized.

[0031] In addition, the distance between multiple rail bodies gradually increases from one end of the rail body to the other, so that tangling of the charging cable can be minimized.

[0089] The rail body (1) may include a beam having a space formed inside, and an opening for forming a rail may be formed in the lower plate of the beam.

[0090] The upper part of the guide (2) can be movably accommodated in the space of the beam.

[0091] The opening of the beam can be located at the lower side of the space of the beam, and the guide (2) can be moved in the longitudinal direction of the rail body (1) along the opening.

[0092] A plurality of rails (13)(14)(15) can be formed on a rail body (1). Each of the plurality of rails (13)(14)(15) can be formed to be long in the longitudinal direction (X) of the rail body (1). The plurality of rails (13)(14)(15) can be spaced apart from each other in the direction (Y) orthogonal to the longitudinal direction (X) of the rail body (1).

[0093] A plurality of guides (2) can be arranged to slide on each of a plurality of rails (13), (14), and (15).

[0094] A plurality of rails (13)(14)(15) can correspond 1:1 with a plurality of guides (2), and when the charger includes a first guide (21), a second guide (22), and a third guide (23), the plurality of rails (13)(14)(15) can include a first rail (13) on which the first guide (21) is slidably guided, a second rail (14) on which the second guide (22) is slidably guided, and a third rail (15) on which the third guide (23) is slidably guided.

[0095] The top plate of each of the multiple guides (2) can be mounted on the rail.

[0096] Each plane of the plurality of guides (2) may be rectangular, and the length (a) may be greater than the width (b).

[0097] Each of the plurality of guides (2) may include an overlapping area (O) and a non-overlapping area (N).

[0098] The overlap area (O) may be an area that overlaps an adjacent guide (2) in the longitudinal direction (X) of the guide (2), as illustrated in Fig. 6. The overlap area (O) may be caught in the longitudinal direction (X) of the guide (2) by an adjacent guide.

[0099] The overlapping area (O) of the first guide (21) overlaps the second guide (22) in the longitudinal direction (X) of the first guide (21) and can be caught in the longitudinal direction (X) of the first guide (21).

[0100] The overlapping area (O) of the second guide (22) overlaps the third guide (23) in the longitudinal direction (X) of the second guide (22) and can be caught in the longitudinal direction (X) of the second guide (22).

[0101] The non-overlapping area (N) may be an area that does not overlap with an adjacent guide in the longitudinal direction (X) of the guide, as illustrated in FIG. 6.

[0102] The non-overlap area (N) of the first guide (21) may not extend over the second guide (22) in the longitudinal direction (X) of the first guide (21).

[0103] The overlap area (N) of the second guide (22) may not overlap the third guide (23) in the longitudinal direction (X) of the second guide (22).

[0104] The first guide (21) may include a non-overlapping area (N) and an overlapping area (O).

[0105] The second guide (23) may include a pair of overlapping areas (O) and a non-overlapping area (N) located between the pair of overlapping areas (O). One of the pair of overlapping areas (O) may overlap with the overlapping area (O) of the first guide (21), and the other of the pair of overlapping areas (O) may overlap with the overlapping area (O) of the third guide (23).

[0106] The third guide (23) may include an overlapping area (O) and a non-overlapping area (N).

[0107] When each of the plurality of guides (2) includes an overlapping area (O) and a non-overlapping area (N), the plurality of guides (2) can move sequentially in the order in which they are arranged on the rail body (1), and tangling of the charging cable (3) can be minimized.

[0108] The guide (2) may include a base (24) and a supporter (26).

[0109] The base (24) can be guided in the longitudinal direction (X) of the rail body (2) along the rail body (2), and the guide (2) can be a linear moving guide.

[0110] When the charging cable (3) is mounted on the supporter (26), the supporter (26) can support the mounted portion of the charging cable (3).

[0111] The supporter (26) may protrude downward from the bottom surface of the base (24). The supporter (26) may be ring-shaped, as illustrated in FIG. 7. The supporter (26) may have an opening (27) formed therein through which a charging cable (3) may pass. The opening (27) may be opened horizontally on either the left or right side of the supporter (26). The opening (27) may be opened in the left-right direction (Y) on either the left or right side of the supporter (26). The charging cable (3) may be inserted and placed through the opening (27) from the side of the supporter (26).

[0112] The opening direction of the opening (27) and the moving direction of the guide (2) can be orthogonal. The guide (2) can be formed so that a space for accommodating the charging cable (3) is open in the forward-backward direction (X) and can move in the forward-backward direction (X). The opening (27) can be formed so as to be open in the left-right direction (Y) on the periphery of the supporter (26).

[0113] When the movement direction (X) of the guide (2) is forward and backward and the insertion direction (Y) of the charging cable (3) is left and right, the movement direction of the guide (2) and the winding direction of the charging cable (2) can be aligned in the forward and backward direction, and the user can move the charging cable (3) by applying less force in the direction in which the charging cable (3) moves.

[0114] The supporters (26) of the multiple guides (2) can be parallel to each other. In this case, the overlap of the charging cables (3) installed on the multiple guides (2) can be minimized.

[0115] An overlapping area (O) can be formed on the base (24), and the supporters (26) of the plurality of guides (2) may not overlap, in which case tangling of the charging cable (3) can be minimized.

[0116] A magnet may be placed on the rail body (1), and an electromagnet (6, see Fig. 6) may be placed on each of the plurality of guides (2). An electromagnet receiving portion (28) in which the electromagnet (6) is received may be formed inside the guide (2). The electromagnet (6) may be electrically connected to a power supply unit.

[0117] When the electromagnets (6) arranged on the plurality of guides (2) are controlled with the same polarity, the plurality of guides (2) can move away from each other due to the repulsive action of the electromagnets (6), and when the electromagnets arranged on the plurality of guides (2) are controlled with the opposite same polarity, the plurality of guides (2) can move closer to each other due to the attractive action of the electromagnets (6).

[0118] It can be locked to the magnet by the on-site magnet and attractive force of the electromagnet (6).

[0119] The charger may include a guide communication module (7) arranged in a guide (2). A communication module receiving portion (29) in which the guide communication module (7) is received may be formed inside the guide (2).

[0120] Examples of communication modules (7) may include BT communication modules and UWB communication modules.

[0121] A user or administrator can communicate with the guide communication module (7) through a mobile terminal, etc., outside the charger, and the guide communication module (7) can receive signals from the mobile terminal, etc.

[0122] The guide communication module (7) can communicate with the communication module provided in the coupler (31), and the electromagnet (6) provided in the guide (2) can be turned on or off according to a command received by the guide communication module (7).

[0123] The charger may further include a flat cable (8). The flat cable (8) may be a power supply unit that supplies power to the electromagnet (6). The flat cable (8) may be arranged in a long direction (X) of the rail body (1). The flat cable (8) may be in a band shape or a plate shape. The flat cable (8) may be accommodated in the space of the beam.

[0124] A flat cable (8) can be arranged between the rail body (1) and the guide (2). The flat cable (8) can be arranged on the upper surface of the guide (2). The flat cable (8) can be extended horizontally, particularly in the front-back direction.

[0125] The flat cable (8) can be energized by the electromagnet (6) of the guide (2) while it is fixed in position on the rail body (1).

[0126] The charger may further include a ball (9).

[0127] The ball (9) can be placed on the upper surface of the guide (2).

[0128] A ball receiving portion (24a) that receives a portion of a ball (9) may be formed on the upper surface of the guide (2). The ball (9) may roll when the guide (2) moves.

[0129] A plurality of balls (9) can be arranged in the charger, and the guide (2) can slide smoothly on the rail body (1).

[0130] Fig. 7 is a diagram illustrating multiple guides according to the present embodiment.

[0131] The supporter (26) of the plurality of guides (2) may have the opening direction of the opening (27) alternately opposite.

[0132] That is, each of the supporters (26) of the plurality of guides (2) (21), (22), and (23) has an opening (27) that is opened in a horizontal direction, and the opening directions of the openings (27) of adjacent guides may be opposite to each other.

[0133] When the opening (27) formed in the supporter (26) of the first guide (21) is formed on the left side of the supporter (26), the opening (27) formed in the supporter (26) of the second guide (22) can be formed on the right side of the supporter (26), and the opening (27) formed in the supporter (26) of the third guide (23) can be formed on the left side of the supporter (26).

[0134] Conversely, when the opening (27) formed in the supporter (26) of the first guide (21) is formed on the right side of the supporter (26), the opening (27) formed in the supporter (26) of the second guide (22) can be formed on the left side of the supporter (26), and the opening (27) formed in the supporter (26) of the third guide (23) can be formed on the right side of the supporter (26).

[0135] When the opening (27) formed in the supporter (26) of the adjacent guide is opened in the opposite direction, the charging cable (3) can be reliably installed on multiple guides (2).

[0136] Figure 8 is a bottom view when guides according to the present embodiment are arranged adjacently.

[0137] The supporters (26) of adjacent guides (22)(23) can be spaced apart in the oblique direction (XY) between the forward-backward direction and the left-right direction.

[0138] The first distance (L1) between the supporters (26) of adjacent guides (22)(23) may be longer than the second distance (L2) between the centers (C) of the supporters (26) of adjacent guides (22)(23).

[0139] The first distance (L1) may be a distance in the forward / backward direction, or may be a distance in the longitudinal direction (X) of the rail body (1).

[0140] The second distance (L2) may be a distance in the left-right direction, or may be a distance in the direction (Y) orthogonal to the longitudinal direction (X) of the rail body (1).

[0141] When the first distance (L1) is longer than the second distance (L2), the radius of curvature of the curved portion of the charging cable (3) can be reduced, and the longitudinal bending of the charging cable (3) can be minimized.

[0142] FIG. 8 is a diagram illustrating a spacer and a charging cable according to the present embodiment, and FIG. 9 is a perspective view illustrating the spacer guide illustrated in FIG. 8.

[0143] The charger may include a plurality of guides (2) and spaced spacers (5).

[0144] When a charger cable (3) is mounted on a plurality of guides (2), the charging cable (3) can be divided into a mounting portion that contacts the guide (2) and is mounted on the guide (2), and a non-contact portion that extends from the mounting portion and does not contact the guide (2) and connects adjacent mounting portions.

[0145] The non-contact portion may be roughly U-shaped or V-shaped.

[0146] The spacer (5) can maintain the charging cable (3) in a shape that does not cause the non-contact portion to bend sharply.

[0147] When the lower part of the non-contact portion is pulled downward, the non-contact portion can have an approximate V shape, and the spacer (5) can guide the non-contact portion so that the non-contact portion is not bent as much as possible and has a U shape or a shape close to a U shape.

[0148] The spacer (5) may include multiple stayer guides (51) (52 (53) and bridges (60).

[0149] Multiple stayer guides (51) (52 (53) can guide different parts of the charging cable (3).
