[0036] Reference Figure 1-5 This embodiment provides an overhead rail charging device, including

[0037] A guide rail 1, inside of which a busbar 2 is provided;

[0038] A charging box 3 is provided with a frame 4 inside, and a driving assembly 5 is provided on the top surface of the frame 4. The driving assembly 5 includes a driving suspension beam 51 hinged to the top surface of one end of the frame and arranged at both ends of the guide rail 1. A servo motor 52 is provided on one side of the driving suspension beam 51, and a driving wheel 53 abutting against the guide rail 1 is provided at the output end of the servo motor 52. A driven wheel 54 corresponding to the driving wheel 53 is provided on the other side of the driving suspension beam 51, and the driven wheel 54 abuts against the other side wall of the guide rail 1;

[0039] Among them, a charging module 6 is provided in the charging box 3, and the charging module 6 is slidably set on the guide rail 1 through a conductor, one end of the conductor is connected to the charging module 6 (can be connected through a wire), and the other end of the conductor is connected to the bus bar 2, so that when the charging box 3 moves on the guide rail 1, the charging module 6 is always in a powered state.

[0040] The guide rail 1 is fixed, and the charging box 3 is driven to slide on the guide rail 1 by the driving component 5, so that the charging box 3 can be conveniently moved to a suitable position for charging as required.

[0041] The charging module 6 is arranged on one side of the frame 4 , and the control module is arranged on the other side of the frame 4 .

[0042] In a preferred embodiment, the driving component 5 also includes a passive suspension beam 55 arranged on the top surface of the other end of the frame 4 and at both ends of the guide rail 1, and driven wheels are arranged at both ends of the passive suspension beam 55 to abut against the side walls of the guide rail 1. In order to improve the stability of the driving component 5 driving the charging box 3 to move on the guide rail 1, a passive suspension beam 55 and driven wheels arranged at both ends of the passive suspension beam 55 are arranged.

[0043] In a preferred embodiment, the charging box 3 further includes a charging cable bending mechanism 7, and the charging cable bending mechanism 7 includes a charging gun 71, the end of which is arranged on a bottom plate 72 on the bottom surface of the frame 4;

[0044] A charging cable 73 connected to an input end of the charging gun 71;

[0045] The cable reel 74 is disposed in two sets of wall panels 75 vertically disposed at both ends of the frame 4, and the charging cable 73 is wound and stored in the cable reel 74 in an orderly manner;

[0046] The conductive slip ring 76 has a bearing housed inside the cable drum 74, and the starting end of the charging cable 73 extends into the cable drum 74 and is electrically connected to the conductive slip ring 76. Since the bearing of the conductive slip ring 76 is arranged inside the cable drum 74, when the cable drum 74 rotates, the conductive slip ring 76 does not rotate. The conductive slip ring 76 is connected to the charging module 6 through a wire, so as to supply power to the charging cable 73. The conductive slip ring 76 can be implemented by using existing technology;

[0047] Among them, one group of the wall panels 75 is provided with a driving component 2 77 for storing or unwinding the charging cable, and the driving component 2 77 is transmission-connected to the cable reel 74 . Two groups of wall panels 75 are provided with a guide component 78 for limiting the charging cable 73 , and the driving component 2 77 is transmission-connected to the guide component 78 .

[0048] The utility model has a simple structure and is easy to operate. While the driving component 77 drives the cable reel 74 to rotate, the driving component 77 drives the guide component 78 to limit the charging cable 73, so that the charging cable 73 is wound or unwound on the cable reel 74 in an orderly manner.

[0049] In a preferred embodiment, the second drive assembly 77 includes a second servo motor 771, which is disposed on one side of the wall panel 75;

[0050] The synchronous pulley 772 is connected to the output end of the servo motor 771. The synchronous pulley 772 is arranged on the outside of the wall panel 5, and the synchronous pulley 772 is connected to the large pulley 774 through the synchronous belt 773. The inner side of the large pulley 774 is connected to the cable reel 74.

[0051] The rotation of the servo motor 2 771 will drive the synchronous pulley 1 772 to rotate, thereby driving the large pulley 774 to rotate, that is, driving the cable reel 74 to rotate accordingly.

[0052] In a preferred embodiment, a synchronous pulley 2 775 is provided on the outer side of the large pulley 774, and the synchronous pulley 2 775 is connected to the synchronous pulley 3 777 through the synchronous belt 2 776. The synchronous pulley 3 777 is connected to the guide assembly 78, and the guide assembly 78 includes a lead screw 781 arranged on the inner side of the synchronous pulley 3 777, and the lead screw 781 is provided with a cable guide wheel 782 for limiting the charging cable.

[0053] When the servo motor 2 771 rotates to drive the large pulley 774 to rotate, the synchronous pulley 2 775 outside the large pulley 774 will drive the synchronous pulley 3 777 to rotate, that is, drive the lead screw 781 to rotate, so that the guide wheel 782 guides and limits the charging cable 73. It should be noted that the drive component 2 77 and the guide component 78 provided in this embodiment are only an implementation method, which should not be a limitation of the present invention.

[0054] In a preferred embodiment, a plurality of limit rods 8 are provided around the cable reel 74 and between the two groups of wall panels 75, and a plurality of flow beads 9 are provided on each group of the limit rods 8. Considering that some charging cables 3 are relatively thick, if only a guide mechanism 78 is provided, the charging cable 73 may not be tightly wound around the cable reel 74 during use. Therefore, a plurality of limit rods 8 and a plurality of flow beads 9 are provided around the cable reel 74, so that the charging cable 73 is tightly wound around the cable reel 74. During the driving process of the servo motor 2 771, the cable reel 74 rotates one circle, and the lead screw 781 rotates one stroke, so that the charging cable 73 is wound around the cable reel 74 in an orderly manner.

[0055] In a preferred embodiment, a reducer is provided at the output end of the servo motor 2 771 , and the output end of the reducer is connected to the synchronous pulley 1 772 . The reducer is provided to facilitate further adjustment of the rotation speed of the cable reel 74 .

[0056] In a preferred embodiment, a tensioning wheel 10 for adjusting the synchronous belt 773 is provided on the wall panel 75 on the same side as the synchronous belt pulley 772.

[0057] The operation process is as follows:

[0058] Fix the guide rail 1, drive the driving wheel 53 to rotate through the servo motor 52 of the driving assembly 5, and drive the charging box 3 to slide on the guide rail 1 with the driven wheel 54, and move the charging box 3 to a suitable position as required;

[0059] When charging the electric vehicle, the charging gun 71 is taken out. When the charging cable 73 needs to be unwound, the servo motor 2 771 is driven to rotate forward, and the servo motor 2 771 drives the synchronous pulley 1 772 to rotate, and drives the large gear 774 to rotate through the synchronous belt 1 773, that is, drives the cable drum 74 to rotate. At the same time, the synchronous pulley 2 775 on the outer side of the large gear 774 drives the synchronous pulley 3 777 to rotate through the synchronous belt 2 776, that is, drives the lead screw 781 of the guide assembly 78 to rotate, so that the cable guide wheel 782 guides and limits the charging cable 73. By setting a plurality of limit rods 8 and a plurality of smooth beads 9 surrounding the cable drum 74, the charging cable 73 is tightly wound on the cable drum 74;

[0060] After charging is completed, when the charging cable 73 needs to be bent and rolled up, the servo motor 2 771 is driven to reverse.

[0061] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
