[0003] Currently, in some parking lots, in order to meet the charging needs of a large number of new energy vehicles, charging piles are often installed on each parking space. This approach will obviously cause a significant increase in costs. In addition, the vehicles parked in the parking spaces are not necessarily in the charging state, that is, the charging piles often exist in an idle state, with a relatively low utilization rate, resulting in a waste of resources.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1-15 , the present invention provides a technical solution, a six-gun ring-shaped 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 frame 4 includes a strip-shaped top plate 4.1 fixed to the top surface of the charging pile main cabinet 1 in the middle of the bottom surface, an annular track 4.2 provided on the periphery of the strip-shaped top plate 4.1, a plurality of support rods 4.3 fixedly connected between the outer peripheral wall of the strip-shaped top plate 4.1 and the inner peripheral wall of the annular track 4.2, and legs 4.4 fixedly connected to both ends of the bottom surface of the strip-shaped top plate 4.1 at the top. A plurality of positioning tracks 4.5 perpendicular to the outer peripheral wall at the inner end are evenly provided on the outer peripheral wall of the annular track 4.2.

An annular cavity 4.2.1 and a column cavity 4.5.1 are respectively provided in the middle of the inner cavities of the annular track 4.2 and the positioning track 4.5. An annular sliding groove 4.2.2 is provided on the bottom surface of the annular track 4.2 corresponding to the middle of the annular cavity 4.2.1, a linear sliding groove 4.5.2 is provided on the bottom surface of the positioning track 4.5 corresponding to the middle of the column cavity 4.5.1, and a side slot 4.2.3 is provided on the outer peripheral wall of the annular track 4.2 corresponding to the inner ends of the column cavity 4.5.1 and the linear sliding groove 4.5.2.

[0042] In the middle of the outer end of the top surface of the positioning track 4.5, there is a square hole 4.5.4. At the bottom of the outer end of the positioning track 4.5, there is a bottom housing 4.5.3. Inside the cavity of the bottom housing 4.5.3, there is a shielding member 4.5.5 for covering the bottom end of the first conductive post 5.4 and for pushing the slider 6.3 upward. On the bottom surface of the bottom housing 4.5.3, there is a chute connected to the linear chute 4.5.2. Among them, the shielding member 4.5.5 includes two inclined slats 4.5.5.1 whose bottom ends are respectively hinged to the top of the two side walls at the inner end of the cavity of the bottom housing 4.5.3, a U-shaped plate 4.5.5.2 whose inner end is fixedly butted to the top end of the inclined slat 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 cavity of the bottom housing 4.5.3.

[0043] The electrical connection member 5 includes a cylindrical housing 5.2 whose bottom end is fixed to the periphery of the square hole 4.5.4, a first insulating disc 5.3 fixedly sleeved at the bottom of the inner cavity of the cylindrical housing 5.2, a plurality of conductive sleeves 5.6 fixedly sleeved along the two sides of the middle of the first insulating disc 5.3 in the vertical direction, a first conductive post 5.4 slidably sleeved inside the conductive sleeve 5.6, and a top pressure spring 5.5 connected between the top surface of the first conductive post 5.4 and the top surface of the inner cavity of the cylindrical housing 5.2. The conductive sleeves 5.6 are respectively electrically connected to the wiring terminals of the charging pile main cabinet 1 through wires.

[0044] Among them, the electrical connection member 5 further includes a clamping plate 5.1 fixedly clamped to the top of the positioning track 4.5 and corresponding to the square hole 4.5.4. The clamping plate 5.1 is provided with a through hole 5.1.1 in the middle. The outer edge of the bottom end of the cylindrical housing 5.2 is fixedly connected to the top surface of the clamping plate 5.1 through bolts and is located at the position outside the through hole 5.1.1. The side wall of the first insulating disc 5.3 is provided with a side hole 5.3.1. A sleeve 5.2.1 is fixed to the outer peripheral wall of the cylindrical housing 5.2 corresponding to the position of the side hole 5.3.1. That is, both sides of the clamping plate 5.1 are fixedly connected to the two side walls of the positioning track 4.5 through bolts. The end of the wire connected to the wiring terminal of the charging pile main cabinet 1 is sleeved inside the sleeve 5.2.1, and then the core wires of the wire are respectively electrically connected to the corresponding conductive sleeves 5.6 through the side holes 5.3.1; and there is an electrical connection relationship between the first conductive post 5.4 and the conductive sleeve 5.6. The top end of the inner cavity of the conductive sleeve 5.6 is provided with an annular notch, and the outer edge of the top end of the first conductive post 5.4 is provided with an annular convex structure that is sleeved and matched with the annular notch. Under the top pressure of the spring 5.5, the bottom end of the first conductive post 5.4 has a tendency to protrude from the bottom surface of the first insulating disc 5.3, but the vertical spring 4.5.5.3 provides an upward thrust to the U-shaped plate 4.5.5.2, so that the top surface of the U-shaped plate 4.5.5.2 fits on the bottom surface of the first insulating disc 5.3, and the first conductive post 5.4 is pushed to a position flush with the bottom surface of the first insulating disc 5.3, thereby realizing the covering and protection of the idle first conductive post 5.4. In order to improve the sealing effect at the covering place, the top surface of the U-shaped plate 4.5.5.2 is coated with a rubber layer.

[0045] The six mobile supports 6 include a box body 6.1, a gun seat 6.2 fixed to the bottom end of the inner cavity of the box body 6.1 and used for inserting the charging gun 3, a sliding block 6.3 fixed to the middle of the top surface of the box body 6.1 and whose top end is slidably clamped with the annular track 4.2 and the positioning track 4.5, a power connection member 6.4 sleeved on the center of the sliding block 6.3, a plurality of grooved wheels 6.6 respectively slidably installed in the inner cavity of the box body 6.1 along the horizontal direction and used for supporting the charging cable 2 to be distributed in a zigzag shape, and elastic support members 6.5 arranged on both sides of the box body 6.1 and used for elastically supporting both ends of the central axis of the grooved wheel 6.6 along the horizontal direction. The power connection member 6.4 includes an insulating disc two 6.4.3 fixedly sleeved on the middle of the sliding block 6.3 and a plurality of conductive columns two 6.4.5 fixedly sleeved on both sides of the middle of the insulating disc two 6.4.3 along the vertical direction. The bottom ends of the conductive columns two 6.4.5 are respectively electrically connected to the core wires at the top end of the charging cable 2.

[0046] Among them, the sliding block 6.3 includes an insulating block 6.3.1 slidably clamped with the top of the annular cavity 4.2.1, the column cavity 4.5.1 and the side notch 4.2.3, and an insulating tube 6.3.2 fixedly connected to the middle of the bottom surface of the insulating block 6.3.1 and whose bottom end is fixedly connected to the middle of the top surface of the box body 6.1. A circular groove 6.3.1.1 fixedly sleeved with the insulating disc two 6.4.3 is formed in the middle of the insulating block 6.3.1. The insulating tube 6.3.2 is slidably clamped with the bottom of the annular sliding groove 4.2.2, the linear sliding groove 4.5.2 and the side notch 4.2.3. In addition, a bottom tube 6.4.4 sleeved and matched with the insulating tube 6.3.2 is fixedly connected to the middle of the bottom surface of the insulating disc two 6.4.3. An outer thread of the bottom end of the bottom tube 6.4.4 is sleeved with a connecting tube 6.4.2. An insulating plate 6.4.1 is fixedly sleeved on the periphery of the middle of the connecting tube 6.4.2. The connecting tube 6.4.2 is fixedly sleeved on the sheath at the top end of the charging cable 2. A top hole 6.1.1 sleeved and matched with the connecting tube 6.4.2 is arranged in the middle of the top surface of the box body 6.1. The top surface of the insulating plate 6.4.1 is pressed against the top surface of the inner cavity of the box body 6.1. Due to the fixing effect of the connecting tube 6.4.2 on the top end of the charging cable 2, the problem that the top end of the charging cable 2 falls off when the charging cable 2 is pulled downward is avoided. When the sliding block 6.3 slides to the position corresponding to the square hole 4.5.4, the positions of the conductive columns two 6.4.5 respectively correspond to the conductive columns one 5.4 one by one.

[0047] On both side walls of the box body 6.1, a plurality of rectangular holes 6.1.2 are vertically provided, which are slidably clamped to both ends of the central axis of the grooved pulley 6.6. The elastic support member 6.5 includes a strip-shaped housing 6.5.1 fixed to both side walls of the box body 6.1 and corresponding to the rectangular holes 6.1.2, a slider 6.5.2 slidably installed in the inner cavity of the strip-shaped housing 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-shaped housing 6.5.1. The strip-shaped housing 6.5.1 is provided with a strip-shaped groove 6.5.1.1 corresponding to one side wall of the box body 6.1 and slidably clamped to the central axis of the grooved pulley 6.6. Both ends of the grooved pulley 6.6 are respectively rotatably sleeved on the slider 6.5.2. In the idle state, the horizontal springs 6.5.3 respectively push the sliders 6.5.2 to the end positions of the inner cavity of the strip-shaped housing 6.5.1, that is, the grooved pulleys 6.6 are respectively located in the front or rear of the inner cavity of the box body 6.1. At this time, the sliders 6.5.2 in the inner cavities of two adjacent strip-shaped housings 6.5.1 are respectively at different ends, so as to ensure that the charging cable 2 sequentially bypassing the grooved pulleys 6.6 can be reciprocally distributed in a zigzag shape, thereby achieving the storage effect of the charging cable 2.

[0048] In order to prevent the rebounding force of the horizontal spring 6.5.3 from forming a pulling-back force on the charging cable 2 during charging, which may cause the charging gun 3 to be pulled out of the socket of the charging vehicle, a check mechanism 7 is also provided. Among them, a round hole 6.1.3 is opened at a position on the bottom end of one side wall of the box body 6.1 far from the gun seat 6.2. The check mechanism 7 includes an arc-shaped groove block 7.1 fixed to the other side wall of the inner cavity of the box body 6.1 and facing the round hole 6.1.3, an arc-shaped pressing plate 7.2 arranged in pairs with the arc-shaped groove block 7.1, guide rods 7.3 vertically fixed to the top and bottom ends of the side wall of the arc-shaped groove block 7.1 and slidably sleeved on the top and bottom ends of the arc-shaped pressing plate 7.2, a telescopic cylinder 7.4 with a piston rod slidably sleeved in the round hole 6.1.3 and the inner end of the piston rod fixedly connected to the middle of the outer side of the arc-shaped pressing plate 7.2, and a housing 7.5 fixed to the outer side wall of the box body 6.1 and sleeved outside the telescopic cylinder 7.4. That is, when the charging cable 2 is pulled outwards through the charging gun 3 for charging preparation, the telescopic cylinder 7.4 is in a contracted state. At this time, the arc-shaped pressing plate 7.2 and the arc-shaped groove block 7.1 are in a separated state. After the charging gun 3 is assembled with the socket of the new energy vehicle to be charged, the telescopic cylinder 7.4 extends the piston rod, so that the arc-shaped pressing plate 7.2 moves towards the arc-shaped groove block 7.1 under the guiding action of the guide rods 7.3. After the arc-shaped pressing plate 7.2 and the arc-shaped groove block 7.1 are combined, sufficient clamping force is provided to the charging cable 2 to achieve the effect of preventing the charging cable 2 from retracting.

[0049] In summary, during use, the entire six-gun ring-shaped charging pile is used to cover eight parking spaces, which are divided into two rows. The main cabinet 1 of the charging pile and the support legs 4.4 are arranged between the two rows of parking spaces. Ten positioning tracks 4.5 are provided and are respectively located directly above both sides of each parking space, so as to adapt to different settings of the charging sockets on the left and right sides of new energy vehicles.

[0050] When a new energy vehicle parked in a parking space needs to be charged, move the nearest and idle moving support member 6, that is, push and pull the whole moving support member 6 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 enters the column cavity 4.5.1 of the positioning track 4.5 through the side notch 4.2.3.

[0051] Continue to push the box body 6.1 outwards, and both sides of the bottom surface of the insulating block 6.3.1 gradually slide to the bottom end of the inclined strip 4.5.5.1. During the continuous sliding process, and with the assistance of the downward pulling force on 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 onto the top surface of the U-shaped plate 4.5.5.2. At this time, release the external force applied to the box body 6.1, and the vertical spring 4.5.5.3 will lift the U-shaped plate 4.5.5.2 upwards, so that the top end of the insulating block 6.3.1 is stuck into the square hole 4.5.4 to complete the one-to-one corresponding electrical connection between the first conductive column 5.4 and the second conductive column 6.4.5.

[0052] Then remove the charging gun 3 from the gun seat 6.2, and then drag the charging cable 2, so that the plurality of grooved wheels 6.6 gradually move towards the middle of the box body 6.1 by compressing the horizontal spring 6.5.3 through the slider 6.5.2 respectively, that is, the charging cable 2 originally distributed in a zigzag shape gradually tends to be in a vertical state. When the charging gun 3 can be inserted into the charging socket of the vehicle to be charged, the check mechanism 7 fixes and clamps the charging cable 2 to prevent the charging cable 2 from retracting.

[0053] After charging is completed, remove the charging gun 3 from the charging socket and release the fixing effect of the check mechanism 7 on the charging cable 2. Under the action of the rebounding force of the horizontal spring 6.5.3, the grooved wheels 6.6 are gradually reset, so as to realize the re-storage of the charging cable 2, and then re-install the charging gun 3 on the gun seat 6.2.

[0054] Then, pull the whole moving support member 6 downward through the box body 6.1, so that the insulating block 6.3.1 compresses the vertical spring 4.5.5.3 through the U-shaped plate 4.5.5.2 until the top end of the insulating block 6.3.1 disengages from the square hole 4.5.4. When pushing the box body 6.1 towards the annular track 4.2, the insulating block 6.3.1 gradually moves away from the inclined strip 4.5.5.1 and slides back into the annular chute 4.2.2 through the side notch 4.2.3. The shielding member 4.5.5 also resets to cover the bottom end of the first conductive column 5.4 again.
