Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a low-power intelligent charging pile. Background Art

[0002] Low-power smart charging piles usually refer to electric vehicle charging equipment with relatively low output power.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The present invention is further described in detail below in conjunction with the embodiments.

[0028] Specific embodiments of the low-power intelligent charging pile provided by the utility model:

[0029] See also Figure 1-6 , a low-power intelligent charging pile includes a charging pile body 1; a mounting plate 2 is provided at the rear of the charging pile body 1, and a shield 4 is connected between the mounting plate 2 and the rear side of the charging pile body 1. In this embodiment, the mounting plate 2 is a rectangular plate, and its corners all protrude from the shield 4. Specifically, the width of the mounting plate 2 is the same as that of the charging pile body 1, and the height of the mounting plate 2 is not higher than the height of the charging pile body 1. The outer dimensions of the shield 4 are smaller than the mounting plate 2, so that the four corners of the mounting plate 2 are exposed, and the corners of the mounting plate 2 are provided with mounting holes 3, which are convenient for fixing the mounting plate 2 to the wall or the upper part of the frame using expansion screws.

[0030] The shield 4 has an opening on one side; in this embodiment, the shield 4 has an opening on the lower side, the width of the shield 4 is the same as the mounting plate 2 and is correspondingly connected, and the height of the shield 4 is less than the height of the mounting plate 2; the shield 4 is in the shape of an inverted U-shaped plate.

[0031] A conductive slip ring 11 is connected to the output end of the charging pile body 1, and a charging cable 6 is electrically connected through the conductive slip ring 11. Specifically, a rotor of the conductive slip ring 11 is electrically connected to the charging cable 6, and a stator of the conductive slip ring 11 is installed on the rear wall of the charging pile body 1 and is electrically connected to the output end of the charging pile body 1; a charging gun 7 is connected to the end of the charging cable 6, and the charging gun 7 is plugged into the charging port of the electric vehicle to realize charging.

[0032] The reel 5 for winding up the charging cable 6 is rotatably mounted inside the shield 4. In this embodiment, the center of the reel 5 has a central axis 12, the front end of the central axis 12 is connected to the rotor of the conductive slip ring 11, and the rear end of the central axis 12 is rotatably connected to the mounting plate 2. In this way, the central axis 12 can rotate, and the charging cable 6 can be retracted and released by driving the reel 5 to rotate. Annular limit plates are provided on the outer sides of the edges of both ends of the reel 5 to limit the winding of the charging cable 6 and prevent the charging cable 6 from escaping from the outside of the reel 5.

[0033] The shield 4 protects the charging cable 6, and the charging cable 6 is rolled up in the shield 4 on the rear side of the charging pile body 1; compared with the structure in the prior art in which the cable is stored at the lower side of the charging pile, the overall structure of this charging pile is more compact, smaller in size, and has stronger integrity.

[0034] A spiral protrusion 8 is provided on the outside of the reel 5, and the protrusion 8 forms a spiral groove on the outside of the reel 5 to accommodate the charging cable 6; when winding, the charging cable 6 is wound along the groove between the protrusions 8, which can be arranged neatly to avoid tangled cables. The height of the protrusion 8 is not less than the outer diameter of the charging cable 6, and the outer edge of the protrusion 8 is rounded to reduce friction on the charging cable 6.

[0035] like Figure 2 , Figure 4 and Figure 6 As shown, the inner end of the charging cable 6 passes through the inside of the reel 5 and is connected to the rotor of the conductive slip ring 11, and the outer end passes around the reel 5 and is connected to the charging gun 7. When the reel 5 rotates, the inner end and the rotor of the charging cable 6 rotate with the reel 5; the outer part of the charging cable 6 is retracted and released as the reel 5 rotates.

[0036] A coil spring 9 is connected between the reel 5 and the inner side of the protective cover 4. Specifically, the inner and outer ends of the coil spring 9 are respectively connected to the central axis 12 and the inner side of the protective cover 4. During the release of the charging cable 6, the reel 5 and the central axis 12 rotate to store energy in the coil spring 9. After charging is completed, the rebound force of the coil spring 9 can cause the reel 5 to rotate automatically, thereby realizing automatic winding of the charging cable 6.

[0037] A damper 10 is provided in the shield 4. Specifically, the damper 10 is installed outside the mounting plate 2 and around the rear end of the central shaft 12. The damper 10 damps the rotation of the reel 5. Without the damper 10, the coil spring 9 causes the reel 5 to rotate quickly, thereby causing the charging cable 6 to reel quickly. The excessive speed leads to certain risks. The damper 10 can suppress the rotation speed of the central shaft 12 and the reel 5 during reeling, thereby improving safety and stability.

[0038] Due to the existence of the coil spring 9, during charging, the coil spring 9 generates a reeling force on the charging cable 6, which continuously acts on the charging cable 6 and the charging gun 7, which may easily cause the connection between the charging gun 7 and the charging cable 6 to bend, deform, or even be damaged. In this embodiment, a clamping structure for clamping the charging cable 6 is provided at the opening of the shield 4. The clamping structure clamps the charging cable 6, suppresses the reeling force at the clamping structure, and prevents the reeling force from being transmitted to the charging gun 7.

[0039] Specifically, the wire clamping structure includes a fixed plate 13, a movable plate 14, a guide rod 15 and a bolt 16; the charging cable 6 passes through the fixed plate 13 and the movable plate 14; in this embodiment, the fixed plate 13 is L-shaped, the movable plate 14 corresponds to and is parallel to a straight section of the fixed plate 13, and the length of the movable plate 14 corresponds to the axial span of the reel 5, and the position corresponds; in this way, the charging cable 6 is always between the movable plate 14 and the fixed plate 13 during the winding process.

[0040] There are two guide rods 15, which are connected to the movable plate 14 and slide through the shield 4; the bolt 16 is rotatably connected to the movable plate 14 and is threadedly connected to the shield 4; the bolt 16 passes through the side wall of the shield 4, and a handle is provided at the end of the bolt 16 away from the movable plate 14. The bolt 16 is rotated by the handle to drive the movable plate 14 to move, thereby changing the distance between the movable plate 14 and the fixed plate 13, thereby realizing the clamping, positioning and release of the charging cable 6.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
