Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a ring-shaped multi-charging position charging pile. Background Art

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or wall and installed in public buildings (such as public buildings, shopping malls, and public parking lots), residential parking lots, or charging stations. They can charge various models of electric vehicles at different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] With the country's promotion of new energy vehicles and the maturity of new energy vehicle technology, more and more people now favor new energy vehicles, which not only saves fuel money, but also makes a strong contribution to environmental protection.

[0004] However, with the increasing popularity of new energy vehicles, the use of charging piles has gradually become increasingly inadequate. Since a full charge takes a long time, users often have to wait in line for long periods of time. Currently, to reduce the waiting time for users to charge, charging piles are installed in every parking space. While this approach can solve the problem of long queues, the construction of multiple charging piles will significantly increase investment costs. In practice, not every vehicle parked in a parking space is actually charging, resulting in low charging pile utilization. The use of a multi-charging charging pile to fully and rationally allocate charging pile resources is an urgent issue that needs to be addressed. Summary of the Invention

[0034] 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.

[0035] See also Figure 1-9 The present invention provides a technical solution, a ring-shaped multi-charging station charging pile, wherein the ring-shaped power supply mechanism 4 includes a plurality of insulating inner rings 4.1 stacked in the middle of the top surface of the charging pile cabinet 1 and a top cover 4.2 covering the top of the top insulating inner ring 4.1. The insulating inner ring 4.1 is provided with a plurality of vertical through-holes 4.1.4 evenly distributed along the circumference. A plurality of fixing rods 4.3 are vertically fixed to the top surface of the charging pile cabinet 1, and are respectively fitted with the through-holes 4.1.4. The top of the fixing rods 4.3 is provided with an external thread 4.3.1, and a compression nut 4.4 is threadedly fitted onto the external thread 4.3.1. The bottom surface of the top cover 4.2 is provided with a sleeve ring 4.2.1, which is fitted with the inner cavity of the top insulating inner ring 4.1. Specifically, multiple stacked insulating inner rings 4.1 are sequentially inserted through perforations 4.1.4 onto fixing rods 4.3. Compression nuts 4.4 are installed and tightened, pressing against the top surface of the top insulating inner ring 4.1 to securely assemble the insulating inner rings 4.1. A top cover 4.2 is secured to the top insulating inner ring 4.1 via a sleeve ring 4.2.1. The top surface of the top cover 4.2 is a spherical convex structure, providing protection for the multiple insulating inner rings 4.1 below.

[0036] The outer peripheral wall of the insulating inner ring 4.1 is vertically provided with a plurality of annular grooves 4.1.1, and the inner cavities of the annular grooves 4.1.1 are respectively fixedly mounted with annular conductors 4.1.2. The inner peripheral wall of the insulating inner ring 4.1 is provided with core wire connectors 4.1.3 respectively electrically connected to the corresponding annular conductors 4.1.2, and the core wire connectors 4.1.3 are electrically connected to the connection terminals of the charging pile cabinet 1.

[0037] The rotating support mechanism 5 includes an insulating outer ring 5.1 that is rotatably sleeved on the outside of the insulating inner ring 4.1, a long shell 5.2 radially fixed to the outer peripheral wall of the insulating outer ring 5.1, a socket 5.3 fixed to the inner cavity of the long shell 5.2 near the outer end and used to insert the charging gun 3, a plurality of groove wheels 5.5 arranged in a zigzag pattern in the inner cavity of the long shell 5.2, and an elastic support member 5.4 provided on the top and bottom surfaces of the long shell 5.2 and used to elastically support the top and bottom ends of the central axis of the groove wheel 5.5 in a direction perpendicular to the axis of the long shell 5.2. The charging cable 2 passes around the plurality of groove wheels 5.5 in sequence, and the inner end of the charging cable 2 is fixed to the outer peripheral wall of the insulating outer ring 5.1. The inner circumference of the insulating outer ring 5.1 is fixed with ring conductors 5.1.1, which are rotatably engaged with annular grooves 4.1.1 and electrically contact the corresponding ring conductors 4.1.2. Cord connectors 5.1.2 are mounted on the outer circumference of the insulating outer ring 5.1, corresponding to the inner cavity of the long housing 5.2. The core wires at the inner ends of the charging cables 2 are electrically connected to the corresponding core connectors 5.1.2. This ensures that the ring conductors 4.1.2 and the corresponding ring conductors 5.1.1 are always in electrical contact, forming a rotating power supply structure and achieving electrical connection between the terminal of the charging pile cabinet 1 and the inner end of the charging cable 2.

[0038] A curved block 5.1.5 is fixed to the outer wall of the insulating outer ring 5.1 at a position corresponding to the inner cavity of the long shell 5.2. A curved clamp 5.1.6 is bolted to the curved block 5.1.5. The curved clamp 5.1.6 and the curved block 5.1.5 form a clamp structure that secures the inner end of the charging cable 2. In other words, the clamp structure formed by the curved clamp 5.1.6 and the curved block 5.1.5 is used to secure the inner end of the charging cable 2 to the sheath, preventing the core wire from falling off the core wire connector 2 5.1.2 when the charging gun 3 pulls the charging cable 2 outward.

[0039] The top and bottom surfaces of the long shell 5.2 are respectively provided with rectangular grooves 5.2.1 in a direction perpendicular to its axis, which are slidably engaged with the top and bottom ends of the central axis of the groove wheel 5.5. The elastic support member 5.4 includes a strip shell 5.4.1 fixed to the top and bottom surfaces of the long shell 5.2 and corresponding to the rectangular groove 5.2.1, a slider 5.4.3 slidably engaged in the inner cavity of the strip shell 5.4.1, and a spring supported between the slider 5.4.3 and one end surface of the inner cavity of the strip shell 5.4.1. A strip groove 5.4.1.1 is provided in the strip shell 5.4.1 near the rectangular groove 5.2.1, which is slidably engaged with the end of the central axis of the groove wheel 5.5.

[0040] In summary, when in use, the parking spaces are distributed in a ring around the periphery of the charging pile. When it is necessary to charge a new energy vehicle parked in the parking spaces within this range, the entire rotating support mechanism 5 is swung by the long housing 5.2 so that the outer end of the long housing 5.2 is aligned with the vehicle to be charged.

[0041] Remove the charging gun 3 from the socket 5.3 and then use it to pull the charging cable 2 outward. As the charging cable 2 is pulled outward, the sheaves 5.5 move toward the centerline of the long housing 5.2, gradually compressing the springs 5.4.4. This process continues until the charging gun 3 can be inserted into the charging port of the vehicle to be charged. The cable 2 is then pulled toward the center of the long housing 5.2 and tends to be straightened.

[0042] After charging is completed, the charging gun 3 is pulled out from the charging socket. Due to the rebound effect of the spring 5.4.4, the groove wheel 5.5 tends to move toward the sides of the long shell 5.2. After the charging cable 2 is relaxed, the groove wheel 5.5 will push the charging cable 2 to both sides, so that the charging cable 2 is arranged in a zigzag shape in the inner cavity of the long shell 5.2 to achieve the storage of the charging cable 2. Finally, the charging gun 3 can be reinserted into the socket 5.3.

[0043] Due to the action of the elastic support member 5.4, after the charging cable 2 is pulled through the charging gun 3 and the charging gun 3 is inserted into the charging socket of the new energy vehicle, a pulling force will be generated on the charging gun 3. In order to prevent the charging gun 3 from being pulled back and falling off from the charging socket, a locking mechanism 6 is provided at the outer end of the long shell 5.2 for preventing the pulled-out charging cable 2 from retracting. The locking mechanism 6 comprises a cylindrical housing 6.5 fixed to the top surface of the outer end of the elongated housing 5.2, a curved base 6.1 fixed to the bottom surface of the outer end of the inner cavity of the elongated housing 5.2, a curved pressure plate 6.2 located above the curved base 6.1, a telescopic cylinder 6.4 with its piston rod fixed to the middle of the top surface of the curved pressure plate 6.2 and sheathed within the inner cavity of the cylindrical housing 6.5, and guide rods 6.3 with their bottom ends fixed perpendicularly to the top surfaces of the curved base 6.1 on both sides and slidingly engaged with the bottom sides of the curved pressure plate 6.2. A circular hole 5.2.2 is provided on the top surface of the outer end of the elongated housing 5.2 at a position corresponding to the cylindrical housing 6.5, which slides with the piston rod of the telescopic cylinder 6.4. When the charging cable 2 is pulled to the new energy vehicle charging port via the charging gun 3, the telescopic cylinder 6.4 extends its piston rod, pushing the curved pressure plate 6.2 downward, causing it to move downward under the guidance of the guide rods 6.3, thereby locking the charging cable 2. In order to avoid interference when the long shells 5.2 swing, the height of the cylindrical shell 6.5 is smaller than the height difference between two adjacent long shells 5.2.

[0044] In order to facilitate the assembly of the elastic support 5.4, wing plates 5.4.1.2 are fixed on both sides of the strip shell 5.4.1 close to the top and bottom surfaces of the long shell 5.2. The wing plates 5.4.1.2 are fixed to the corresponding top and bottom surfaces of the long shell 5.2 with screws.

[0045] In order to improve the smooth movement of the groove wheel 5.5 in the direction perpendicular to the axis of the long shell 5.2, the inner cavity of the strip shell 5.4.1 is away from the end of the spring 5.4.4 and the guide wheel 5.4.2 is rolled on the card. The side wall of the slider 5.4.3 away from the spring 5.4.4 is abutted against the outer wall of the guide wheel 5.4.2. The center of the guide wheel 5.4.2 is provided with a column cavity 5.4.2.1, and the top and bottom ends of the central axis of the groove wheel 5.5 are respectively fixedly docked with plug-in columns 5.5.1 that are socketed and matched with the column cavity 5.4.2.1.

[0046] In order to improve the sealing effect between adjacent insulating outer rings 5.1, an annular groove 5.1.4 is fixed on the top surface of the insulating outer ring 5.1 near the outer edge, and an annular protrusion 5.1.3 is provided on the bottom surface of the insulating outer ring 5.1 near the outer edge, which is rotatably engaged with the annular groove 5.1.4.
