Description

Technical Field

[0001] The utility model mainly relates to the technical field of charging gun cables, and in particular to a curling mechanism of a charging gun cable. Background Art

[0002] As a new energy vehicle, electric vehicles need to be charged with a charging gun. The length of the cable connecting the existing charging pile to the charging gun is usually several times the height of the charging pile, generally about 5 to 10 meters. When the charging gun is inserted into the charging pile, the cable is basically in a dragging state, which can easily cause cable wear and leakage, and easily affect people's travel. If the cable is wound up and hung after each charging, the operation is also cumbersome, time-consuming and labor-intensive.

[0003] For example, the new energy vehicle charging gun cable storage device disclosed in the authorization announcement number CN220700921U includes a turntable for winding and storing the charging gun cable and a charging pile arranged on the outside of the turntable. The turntable is provided with a turnover cable for powering the charging pile, and an external terminal box for the turnover cable. The turntable includes a chassis fixedly installed on the outer end face of the charging column and a middle plate rotatably installed on the outer end of the chassis. The outer end of the middle plate is fixedly sleeved with a surface plate, and the charging gun cable is wound and installed on the surface plate. The surface plate can be rotated by a handle, so that it is convenient for personnel to retract and release the charging gun cable, so that the charging gun cable is wound on the turntable in an orderly manner. The charging pile is installed at the outer end of the surface plate and is powered by a turnover cable. The turnover cable is switched and moved between two sets of spiral cable reel cable grooves to eliminate the torque generated by the rotation, and the cable rotation kinks and causes damage. A guide is also provided at the outer end of the turntable to improve the sliding property of the charging gun cable.

[0004] The storage device provided by the above technical solution has a complex structure and is manually stored, which is cumbersome to operate. On this basis, and in order to meet the diversified development of the market, a curling mechanism for a charging gun cable is proposed. Utility Model Content

[0032] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and all adopt the existing technology. At the same time, the content of the above background technology belongs to the technical cognition scope of the utility model inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute the prior art.

[0033] Reference Figure 1-3 This embodiment provides a curling mechanism for a charging gun cable, comprising:

[0034] A charging gun 1, the end of which is arranged on a bottom plate 2;

[0035] Charging cable 3, connected to the input end of charging gun 1;

[0036] The cable reel 4 is arranged in two sets of wall panels 5 arranged perpendicularly to the two ends of the bottom plate 2, and the charging cable 3 is wound and stored in the cable reel 4 in an orderly manner;

[0037] The conductive slip ring 6 has a bearing housed inside the cable drum 4, and the starting end of the charging cable 3 extends into the cable drum 4 and is electrically connected to the conductive slip ring 6. Since the bearing of the conductive slip ring 6 is arranged inside the cable drum 4, when the cable drum 4 rotates, the conductive slip ring 6 does not rotate. The conductive slip ring 6 is connected to the charging module through a wire, so as to supply power to the charging cable 3. The conductive slip ring 6 can be implemented by the existing technology;

[0038] Among them, one group of the wall panels 5 is provided with a driving component 7 for storing or unwinding the charging cable 3, and the driving component 7 is transmission-connected to the cable reel 4, and two groups of wall panels 5 are provided with a guide component 8 for limiting the charging cable 3, and the driving component 7 is transmission-connected to the guide component 8.

[0039] The utility model has a simple structure and is easy to operate. When the driving assembly 7 drives the cable reel 4 to rotate, the driving assembly 7 drives the guide assembly 8 to limit the charging cable 3, so that the charging cable 3 is wound or unwound on the cable reel 4 in an orderly manner.

[0040] In a preferred embodiment, the driving assembly 7 includes a servo motor 71, which is arranged on one side of a wall panel 5; a synchronous pulley 72, which is connected to the output end of the servo motor 71, and the synchronous pulley 72 is arranged on the outside of the wall panel 5, and the synchronous pulley 72 is connected to the large pulley 74 through a synchronous belt 73, and the inner side of the large pulley 74 is connected to the cable reel 4.

[0041] The rotation of the servo motor 71 will drive the synchronous pulley 1 72 to rotate, thereby driving the large pulley 74 to rotate, that is, driving the cable reel 4 to rotate accordingly.

[0042] In a preferred embodiment, a synchronous pulley 2 75 is provided on the outer side of the large pulley 74, and the synchronous pulley 2 75 is connected to the synchronous pulley 3 77 through the synchronous belt 2 76. The synchronous pulley 3 77 is connected to the guide assembly 8, and the guide assembly 8 includes a lead screw 81 arranged on the inner side of the synchronous pulley 3 77, and the lead screw 81 is provided with a cable guide wheel 82 for limiting the charging cable 3.

[0043] When the servo motor 71 rotates to drive the large pulley 74 to rotate, the synchronous pulley 2 75 outside the large pulley 74 will drive the synchronous pulley 3 77 to rotate, that is, drive the lead screw 81 to rotate, so that the cable guide wheel 82 guides and limits the charging cable 3. It should be noted that the drive assembly 7 and the guide assembly 8 provided in this embodiment are only an implementation method, which should not be a limitation of the present utility model.

[0044] In a preferred embodiment, a plurality of limit rods 9 are provided around the cable reel 4 and between the two groups of wall panels 5, and a plurality of flow beads 10 are provided on each group of the limit rods 9. Considering that some charging cables 3 are relatively thick, if only a guide mechanism 8 is provided, the charging cable 3 may not be tightly wound around the cable reel 4 during use. Therefore, a plurality of limit rods 9 and a plurality of flow beads 10 are provided around the cable reel 4, so that the charging cable 3 is tightly wound around the cable reel 4. During the driving process of the servo motor 71, the cable reel 4 rotates one circle, and the lead screw 81 rotates one stroke, so that the charging cable 3 is wound around the cable reel 4 in an orderly manner.

[0045] In a preferred embodiment, a reducer is provided at the output end of the servo motor 71, and the output end of the reducer is connected to a synchronous pulley 72. The reducer is provided to facilitate further adjustment of the rotation speed of the cable reel 4.

[0046] In a preferred embodiment, a tensioning wheel 11 for adjusting the synchronous belt 73 is provided on the wall panel 5 at the same side as the synchronous belt pulley 72 .

[0047] The operation process is as follows:

[0048] When the charging cable 3 needs to be rolled up, the servo motor 71 is driven to reverse, and the servo motor 71 drives the synchronous pulley 1 72 to rotate, and drives the large gear 74 to rotate through the synchronous belt 1 73, that is, drives the cable reel 4 to rotate, and at the same time, the synchronous pulley 2 75 on the outer side of the large gear 74 drives the synchronous pulley 3 77 to rotate through the synchronous belt 2 76, that is, drives the lead screw 81 of the guide assembly 8 to rotate, so that the cable guide wheel 82 guides and limits the charging cable 3, and by providing a plurality of limit rods 9 and a plurality of smooth beads 10 surrounding the cable reel 4, the charging cable 3 is tightly wound on the cable reel 4;

[0049] When the charging cable 3 needs to be unwound, the servo motor 71 is driven to rotate forward.

[0050] 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.
