DESCRIPTION OF EMBODIMENT

[0048] According to a charging system of a vertical rotary type parking apparatus according to an embodiment of the present invention, as linear busbars through which power is supplied are mounted on the left and right frames of the parking apparatus, and a collector that is slidably coupled with the busbars for receiving electricity and a charger are mounted in each hanger on which a vehicle is loaded, electric vehicles may be charged during parking.

[0049] A vertical rotary type parking apparatus in which the charging system according to an embodiment of the present invention is not installed, referring to FIG. 5, includes: a pair of frames 10 arranged apart from each other; a rail 16 having a track shape that is fixed on each of the frames 10 and includes a curved section 16a disposed at each of upper and lower sides and a linear section 16b disposed at each of left and right sides; a pair of main chains 12 that are movably coupled to each of the rail 16 and circulated and rotated by power of a motor 11; a plurality of pallet holders 13, each having one end portion being fixed on each of the main chains 12 facing each other at regular intervals; and a hanger 19 that is pivotably connected to each of the pallet holders 13 and on which a vehicle is loaded.

[0050] The hanger 19 includes a pivot shaft 15 having both end portions rotatably connected to the pallet holders 13 facing each other, a pair of horizontal bars 18, center portions of the horizontal bars 18 being fixed on both end portions of the pivot shaft 15, a pallet 14 on which a vehicle is loaded, and an arm pipe 17 connecting the horizontal bars 18 to the pallet 14 so that the pallet 14 maintains a horizontal state.

[0051] FIGS. 6A and 6B show a state of the parking apparatus of FIG. 5 in which the charging system according to an embodiment of the present invention is installed.

[0052] The charging system according to an embodiment of the present invention includes busbars 20a and 20b fixed on the frames 10 and through which power is supplied, a collector 30 that is eccentrically arranged on the horizontal bars 18 of the hanger 19 and sliding along the busbars 20a and 20b and a charger 34 for charging electricity, and a distribution panel 28 that supplies power by connecting a power cable to each of the busbars 20a and 20b.

[0053] The charging system according to an embodiment of the present invention, as illustrated in FIG. 6A, may perform charging through a charging cable 35 while an electric vehicle 36 is parked on the pallet 14.

[0054] Referring to FIGS. 7, 9B, and 13A, the collector 30 is mounted on the horizontal bars 18 by means of a bracket 33 to be apart from the pivot shaft 15 by a certain distance.

[0055] For example, as in the related art, when the collector 30 according to an embodiment of the present invention is mounted on the pivot shaft 15 that is a pivot center of the hanger 19, the structure thereof is complicated and a pivot collection element like a slip ring that is expensive is required, but in the present invention, as illustrated in FIGS. 10 to 12, the collector 30 is mounted on the horizontal bars 18 to be apart from the pivot shaft 15 by a certain distance, and thus, a pivot collection element like a slip ring is not required for performing safe electricity feeding.

[0056] Referring to FIGS. 6B and 13A, the busbars 20a and 20b are fixed on the frames 10 corresponding to the linear section 16b of the rail 16 by means of a plurality of fixing brackets 27 and a fixing device 26.

[0057] Each of the fixing brackets 27 may be simply fixed to the frames 10 by bolting, and may be simply mounted by bolting each of the busbars 20a and 20b by using the fixing device 26.

[0058] Referring to FIGS. 7 and 9B, the busbars 20a and 20b are arranged asymmetrically in the left and right sides at distances a and b from a center portion C of the rail 16.

[0059] Accordingly, the fixing brackets 27 for fixing the left busbar 20a and the right busbar 20b are fixed on the frames 10 with different lengths and shapes at left and right.

[0060] In the above-described parking apparatus, the hanger 19 has a structure to circulate and rotate by the main chains 12, and the collector 30 has a structure of being eccentrically arranged on the hanger 19. By asymmetrically arranging the locations of the busbars 20a and 20b at the left and right, during circulation and rotation of the hanger 19, the collector 30 may always be coupled to each of the busbars 20a and 20b regardless of whether the hanger 19 is located at the left or right with respect to the center portion C of the rail 16.

[0061] Furthermore, in the charging system according to the present invention, as the busbars 20a and 20b are disposed only in the linear sections at the left and right sides of the rail 16, not in the curved sections at the upper and lower sides, short-circuit or electric shock according to a derailment problem or foreign material accumulation that may occur in the curved section may be prevented in advance.

[0062] Referring to FIGS. 6B, 8, and 13B, an upper trumpet tube 24 having a wide entrance is coupled to an upper end of each of the busbars 20a and 20b and a lower trumpet tube 25 is coupled to a lower end thereof.

[0063] Accordingly, the collector 30 may safely enter each of the busbars 20a and 20b and smoothly slide therealong.

[0064] The collector 30 includes a guide roller 31 guided by the upper trumpet tube 24 and the lower trumpet tube 25, and a carbon brush 32 sliding on each of the busbars 20a and 20b.

[0065] Referring to FIGS. 13A and 13B, each of the busbars 20a and 20b includes a non-conductive casing 23 with one open side, and at least a pair of copper plates 22 arranged apart from each other in the casing 23 and through which power is supplied and slidably coupled with the carbon brush 32.

[0066] Referring to FIGS. 9A and 9C, the above configuration enables supply of electricity in parallel by dividing the copper plates 22 into several sections at a certain distance. In other words, the copper plates 22 are not present in a certain section so that an electricity feeding section is divided.

[0067] For example, as electricity is supplied in parallel by dividing the left busbar 20a into two or more feeding sections and the right busbar 20b into two or more feeding sections, the capacity of the busbars 20a and 20b may be reduced to be economical and safety may be increased.

[0068] The copper plates 22 of each of the busbars 20a and 20b are arranged in the casing 23 to have an electrical contact with the carbon brush 32, thereby solving a safety problem.
