[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1-15 The present invention provides a technical solution, a one-machine six-gun ring charging pile, including a charging pile main cabinet 1, a charging cable 2 and a charging gun 3 assembled at the bottom end of the charging cable 2.

[0040] The support rail 4 comprises a strip-shaped top plate 4.1, the middle portion of which is fixed to the top of the charging pile main cabinet 1; a circular track 4.2, which is located around the periphery of the strip-shaped top plate 4.1; a plurality of support rods 4.3, which are fixedly connected between the outer wall of the strip-shaped top plate 4.1 and the inner wall of the circular track 4.2; and support legs 4.4, whose top ends are fixedly connected to the bottom ends of the strip-shaped top plate 4.1. The outer wall of the circular track 4.2 is evenly distributed with a plurality of positioning rails 4.5, whose inner ends are fixed perpendicularly to the outer wall.

[0041] The annular track 4.2 is an oblong structure. An annular cavity 4.2.1 and a column cavity 4.5.1 are centrally located within the annular track 4.2 and the positioning track 4.5, respectively. An annular chute 4.2.2 is located on the bottom surface of the annular track 4.2, corresponding to the center of the annular cavity 4.2.1. A linear chute 4.5.2 is located on the bottom surface of the positioning track 4.5, corresponding to the center of the column cavity 4.5.1. Side notches 4.2.3 are located on the outer peripheral wall of the annular track 4.2, directly opposite the inner ends of the column cavity 4.5.1 and the linear chute 4.5.2.

[0042] A square hole 4.5.4 is provided in the middle of the outer end of the top surface of the positioning track 4.5. A bottom shell 4.5.3 is provided at the bottom of the outer end of the positioning track 4.5. The inner cavity of the bottom shell 4.5.3 is provided with a shielding member 4.5.5 for covering the bottom end of the conductive column 5.4 and for pushing the sliding block 6.3 upward. The bottom surface of the bottom shell 4.5.3 is provided with a slide connected to the linear slide 4.5.2. Among them, the shielding member 4.5.5 includes two inclined slats 4.5.5.1, the bottom ends of which are respectively hinged to the top of the two side walls of the inner end of the inner cavity of the bottom shell 4.5.3, a U-shaped plate 4.5.5.2, the inner end of which is fixedly docked to the top of the inclined slats 4.5.5.1, and a vertical spring 4.5.5.3 connected between the outer end of the bottom surface of the U-shaped plate 4.5.5.2 and the outer end of the bottom surface of the inner cavity of the bottom shell 4.5.3.

[0043] The electrical connection component 5 includes a cylindrical shell 5.2 with its bottom end fixed to the periphery of the square hole 4.5.4, an insulating disk 5.3 fixedly mounted on the bottom of the inner cavity of the cylindrical shell 5.2, multiple conductive sleeves 5.6 fixedly mounted vertically on both sides of the middle of the insulating disk 5.3, a conductive column 5.4 slidingly mounted within the conductive sleeve 5.6, and a pressure spring 5.5 connected between the top surface of the conductive column 5.4 and the top surface of the inner cavity of the cylindrical shell 5.2. The conductive sleeves 5.6 are electrically connected to the terminal of the charging pile main cabinet 1 via wires.

[0044] The electrical connection member 5 also includes a card plate 5.1 fixedly connected to the top of the positioning track 4.5 and corresponding to the square hole 4.5.4. The card plate 5.1 has a through hole 5.1.1 in the center. The outer edge of the bottom end of the cylindrical shell 5.2 is fixedly connected to the top surface of the card plate 5.1 by bolts and is located outside the through hole 5.1.1. The side wall of the insulating disk 5.3 is provided with a side hole 5.3.1. The outer wall of the cylindrical shell 5.2 has a sleeve 5.2.1 fixed to the position corresponding to the side hole 5.3.1. That is, the two sides of the card plate 5.1 are fixedly connected to the two side walls of the positioning track 4.5 using bolts. The end of the wire connected to the terminal of the charging pile main cabinet 1 is inserted into the sleeve 5.2.1, and then the core wire of the wire is electrically connected to the corresponding conductive sleeve 5.6 through the side hole 5.3.1. The conductive column 1 5.4 and the conductive sleeve 5.6 are electrically connected. An annular notch is located at the top of the inner cavity of the conductive sleeve 5.6, and an annular protrusion is located on the outer edge of the top of the conductive post 5.4, which fits snugly into the notch. Under the pressure of the spring 5.5, the bottom of the conductive post 5.4 tends to protrude from the bottom of the insulating disk 5.3. However, the vertical spring 4.5.5.3 provides an upward thrust on the U-shaped plate 4.5.5.2, causing the top surface of the U-shaped plate 4.5.5.2 to fit against the bottom of the insulating disk 5.3 and press the conductive post 5.4 until it is flush with the bottom of the insulating disk 5.3, thereby providing protective coverage for the idle conductive post 5.4. To enhance the sealing effect of the covering area, the top surface of the U-shaped plate 4.5.5.2 is coated with a rubber layer.

[0045] The six movable support members 6 include a box body 6.1, a gun holder 6.2 fixed to the bottom of the inner cavity of the box body 6.1 and used to insert the charging gun 3, a sliding block 6.3 fixed to the middle of the top surface of the box body 6.1 and the top of which is slidably engaged with the circular track 4.2 and the positioning track 4.5, a power connection member 6.4 mounted in the center of the sliding block 6.3, a plurality of grooved wheels 6.6 respectively mounted in the inner cavity of the box body 6.1 for sliding horizontally and used to support the charging cable 2 in a zigzag distribution, and elastic support members 6.5 provided on both sides of the box body 6.1 and used to elastically support the two ends of the central axis of the grooved wheel 6.6 in the horizontal direction. The power connection member 6.4 includes an insulating disk 2 6.4.3 fixedly mounted in the middle of the sliding block 6.3 and a plurality of conductive columns 2 6.4.5 fixedly mounted on both sides of the middle of the insulating disk 2 6.4.3 vertically. The bottom ends of the conductive columns 2 6.4.5 are respectively electrically connected to the core wires at the top of the charging cable 2.

[0046] The sliding block 6.3 comprises an insulating block 6.3.1 that slides and engages with the annular cavity 4.2.1, the column cavity 4.5.1, and the top of the side notch 4.2.3; and an insulating tube 6.3.2 that is fixedly connected to the middle of the bottom surface of the insulating block 6.3.1 and its bottom end is fixedly connected to the middle of the top surface of the box body 6.1. The insulating block 6.3.1 has a circular groove 6.3.1.1 in the center that is fixedly connected to the second insulating disc 6.4.3. The insulating tube 6.3.2 slides and engages with the bottom of the annular groove 4.2.2, the linear groove 4.5.2, and the side notch 4.2.3. A bottom tube 6.4.4, which fits snugly with the insulating tube 6.3.2, is fixedly connected to the middle of the bottom surface of insulating disk 2 6.4.3. A connecting tube 6.4.2 is threadedly connected to the outer end of the bottom of bottom tube 6.4.4. An insulating plate 6.4.1 is fixedly connected to the outer periphery of the middle of connecting tube 6.4.2. Connecting tube 6.4.2 is fixedly connected to the sheath at the top of charging cable 2. A top hole 6.1.1 is provided in the middle of the top surface of the box body 6.1, which fits snugly with connecting tube 6.4.2. The top surface of insulating plate 6.4.1 is pressed tightly against the top surface of the inner cavity of box body 6.1. The fixing effect of connecting tube 6.4.2 on the top of charging cable 2 prevents the top of charging cable 2 from falling off when pulling downward. When sliding block 6.3 slides to the position corresponding to square hole 4.5.4, the position of conductive post 2 6.4.5 corresponds one-to-one with conductive post 1 5.4.

[0047] The two side walls of the box body 6.1 are respectively provided with a plurality of rectangular holes 6.1.2 in the vertical direction, which are slidably engaged with the two ends of the central axis of the grooved wheel 6.6. The elastic support member 6.5 includes a strip shell 6.5.1 fixed to the two side walls of the box body 6.1 and corresponding to the rectangular holes 6.1.2, a slider 6.5.2 slidably engaged in the inner cavity of the strip shell 6.5.1, and a horizontal spring 6.5.3 supported between the slider 6.5.2 and one end wall of the inner cavity of the strip shell 6.5.1. A strip groove 6.5.1.1 is provided on one side wall of the strip shell 6.5.1 corresponding to the box body 6.1, which is slidably engaged with the central axis of the grooved wheel 6.6. The two ends of the grooved wheel 6.6 are respectively rotatably sleeved on the slider 6.5.2. In the idle state, the horizontal spring 6.5.3 pushes the slider 6.5.2 to the end position of the inner cavity of the strip shell 6.5.1, so that the grooved wheel 6.6 is located at the front or rear of the inner cavity of the box body 6.1. At this time, the sliders 6.5.2 of the inner cavities of two adjacent strip shells 6.5.1 are at different ends, so as to ensure that the charging cables 2 that pass by the grooved wheel 6.6 in turn can be distributed back and forth in a zigzag shape, thereby achieving the storage effect of the charging cable 2.

[0048] To prevent the rebound force of the horizontal spring 6.5.3 from pulling back on the charging cable 2 during charging, thereby causing the charging gun 3 to be pulled out of the charging vehicle's socket, a backstop mechanism 7 is also provided. A circular hole 6.1.3 is provided at the bottom end of one side wall of the housing 6.1, away from the gun holder 6.2. The backstop mechanism 7 comprises an arcuate groove block 7.1 fixed to the other side wall of the inner cavity of the housing 6.1 and directly opposite the circular hole 6.1.3; an arcuate pressure plate 7.2 paired with the arcuate groove block 7.1; a guide rod 7.3 perpendicularly fixed to the top and bottom ends of the side wall of the arcuate groove block 7.1 and slidably engaged with the top and bottom ends of the arcuate pressure plate 7.2; a telescopic cylinder 7.4 with a piston rod slidably engaged in the circular hole 6.1.3 and a fixed inner end of the piston rod to the middle outer side of the arcuate pressure plate 7.2; and a cover 7.5 fixed to the outer wall of the housing 6.1 and sleeved on the exterior of the telescopic cylinder 7.4. When the charging cable 2 is pulled outward through the charging gun 3 to prepare for charging, the telescopic cylinder 7.4 is retracted, and the curved pressure plate 7.2 is separated from the curved groove block 7.1. When the charging gun 3 is assembled with the new energy vehicle inlet to be charged, the telescopic cylinder 7.4 extends the piston rod, causing the curved pressure plate 7.2 to move toward the curved groove block 7.1 under the guidance of the guide rod 7.3. After the curved pressure plate 7.2 and the curved groove block 7.1 are combined, they provide sufficient clamping force on the charging cable 2 to prevent it from retracting.

[0049] In summary, the six-pronged circular charging station is designed to cover eight parking spaces, divided into two rows. The charging station main cabinet 1 and legs 4.4 are positioned between the two rows of parking spaces. Ten positioning rails 4.5 are provided, located directly above each parking space on either side to accommodate the different left and right charging socket configurations for new energy vehicles.

[0050] When a new energy vehicle parked in a parking space needs to be charged, the nearest and idle mobile support 6 is moved, that is, the mobile support 6 is pushed and pulled as a whole through the box body 6.1, so that the insulating block 6.3.1 first slides along the annular cavity 4.2.1 of the annular track 4.2. When the insulating block 6.3.1 moves to the positioning track 4.5 corresponding to the vehicle to be charged, the insulating block 6.3.1 is passed through the side notch 4.2.3 into the column cavity 4.5.1 of the positioning track 4.5.

[0051] Continue to push the box body 6.1 outward, and the two sides of the bottom surface of the insulating block 6.3.1 gradually slide to the bottom end of the inclined slat 4.5.5.1. During the sliding process, and with the help of the force pulling down the box body 6.1, the vertical spring 4.5.5.3 will be compressed, so that the insulating block 6.3.1 can finally slide to the top surface of the U-shaped plate 4.5.5.2. At this time, the external force applied to the box body 6.1 is released, and the vertical spring 4.5.5.3 will lift the U-shaped plate 4.5.5.2 upward, so that the top of the insulating block 6.3.1 is stuck in the square hole 4.5.4, thereby completing the one-to-one electrical connection between the conductive column 1 5.4 and the conductive column 2 6.4.5.

[0052] Then remove the charging gun 3 from the gun holder 6.2, and then drag the charging cable 2 so that the multiple grooved wheels 6.6 compress the horizontal springs 6.5.3 through the slider 6.5.2 and gradually move toward the middle of the box 6.1, so that the charging cable 2 that was originally distributed in a zigzag shape gradually tends to a vertical state. When the charging gun 3 can be inserted into the charging socket of the vehicle to be charged, the non-return mechanism 7 fixes and clamps the charging cable 2 to prevent the charging cable 2 from retracting.

[0053] After charging is completed, unplug the charging gun 3 from the charging socket and release the fixing effect of the non-return mechanism 7 on the charging cable 2. Under the rebound force of the horizontal spring 6.5.3, the grooved wheels 6.6 are gradually reset, thereby re-storing the charging cable 2, and then the charging gun 3 is reinserted on the gun holder 6.2.

[0054] Then, the entire movable support 6 is pulled downward through the housing 6.1, causing the insulating block 6.3.1 to compress the vertical spring 4.5.5.3 via the U-shaped plate 4.5.5.2 until the top of the insulating block 6.3.1 is released from the square hole 4.5.4. The housing 6.1 is then pushed toward the annular track 4.2, gradually removing the insulating block 6.3.1 from the inclined slats 4.5.5.1 and sliding back into the annular chute 4.2.2 through the side notch 4.2.3. The shield 4.5.5 is also reset to re-cover the bottom of the conductive column 1 5.4.
