The middle of the two sets of inclined baffles 27 is rotatably installed with two sets of auxiliary cylinders 28. The two sets of connecting cables 16 are respectively located in the middle of the four sets of auxiliary cylinders 28. A human-machine interface panel 11 and an intelligent identification module 12 are fixedly installed at the front end of the charging box 1. Parts of the slow charging gun 15 and the fast charging gun 17 are respectively inserted into the interior of the two sets of placement seats 14. The human-machine interface panel 11 and the intelligent identification module 12 are both electrically connected to the energy management module 19. A heat dissipation mechanism 13 is installed through one end of the charging box 1, and multiple sets of heat dissipation holes 18 are opened through the other end of the charging box 1. The multiple sets of heat dissipation holes 18 are aligned with the heat dissipation mechanism 13.
[0019] The specific setup and function of this embodiment will be described in detail below. The charging box 1, as the installation carrier and protective shell of the overall equipment, is made of high-strength metal material and has dustproof and waterproof characteristics (IP54 and above). The interior forms a closed space to protect the core components. Its front end integrates human-computer interaction and recognition functions, and charging interfaces are arranged at both ends. The interior houses the energy management and cable management system. The overall structure is compact and easy to install in photovoltaic energy storage charging station scenarios.
[0020] Charging interface components: Charging box 1 has symmetrically installed placement seats 14 at both ends for positioning and fixing the charging gun. The inner side of the placement seat has elastic buckles to firmly clamp the charging gun handle and prevent shaking or falling. One end of the charging box 1 is equipped with a slow charging gun 15 (suitable for AC charging needs) and the other end is equipped with a fast charging gun 17 (suitable for DC fast charging needs). Both types of charging guns adopt a mis-insertion prevention interface design that conforms to GB / T standards and has insulation protection and anti-arc function. Both the slow charging gun 15 and the fast charging gun 17 are connected to the internal system through connecting cables 16. The cables are made of weather-resistant rubber sheath and have tensile strength and high and low temperature resistance (-30℃ to 85℃). The internal wire core is made of high conductivity copper material to reduce transmission loss.
[0021] The fixed frame 21 adopts a welded steel structure, and its lower end is bolted to the bottom of the charging box, providing stable support for the entire mechanism; two sets of support seats 22 are fixed to the upper end of the fixed frame, and the rotating rod 24 is rotatably installed between the support seats through bearings. As the core component for cable winding, its outer wall is processed with spiral grooves to guide the connecting cable 16 to wind in an orderly manner and avoid messy stacking. Drive and limit unit: A set of support bases are equipped with a variable speed motor 23, which is connected to one end of the rotating rod 24 through a reducer to realize the power drive for cable winding and unwinding; the other end of the rotating rod is fixed with a limit sensor 25 (using a Hall sensor or photoelectric encoder), which can detect the number of rotations of the rotating rod in real time, calculate the cable winding and unwinding length, and send a signal to the energy management module when the preset maximum unwinding length or winding end point is reached to control the motor to stop, so as to prevent the cable from being overstretched or wound too tightly; Protection and guiding structure: Two sets of circular baffles 26 are fixed on the outer wall of the rotating rod to limit the axial displacement of the cable; an inclined baffle 27 is installed at the upper end of the support base, and two sets of auxiliary cylinders 28 are rotatably set in the middle. The connecting cable 16 passes through the two sets of auxiliary cylinders. During the winding and unwinding process, the auxiliary cylinders roll with the cable to reduce friction loss and avoid direct contact between the cable and the corners of the box, which would cause wear. Conductive transmission component: an electric slip ring 29 is fixed to the outer wall of the rotating rod 24. The end of the connecting cable 16 is electrically connected to one end of the electric slip ring, and the other end of the electric slip ring is connected to the energy management module 19 through an internal wire to ensure the continuity and stability of power transmission when the rotating rod rotates, and to adapt to the high current (such as 500A and above) transmission requirements in fast charging scenarios.
[0022] Control and Interaction System: The energy management module 19 is installed on the inner side wall of the charging box. As the core control unit, it integrates a microprocessor, a current / voltage detection module, and a communication module (supporting communication with the energy storage battery and photovoltaic inverter of the photovoltaic energy storage system). It can monitor the charging status in real time, adjust the output power, and link with the cable winding mechanism, human-machine interface panel, and intelligent identification module to achieve automated control. The human-machine interface panel 11 is fixed to the front of the charging box, including a touch screen and a physical emergency button. It can display information such as charging power, remaining time, and cost, support users to select charging modes (such as timed charging and full charging), and has a fault alarm prompt function. The intelligent recognition module 12 is integrated with the human-machine interaction panel and includes a high-definition camera and an image recognition chip. It can automatically identify the charging type (fast charging / slow charging) that is compatible with the vehicle model by scanning the vehicle's charging port or the user's APP QR code, and send instructions to the energy management module to prepare the corresponding charging gun cable retraction and extension actions in advance.
[0023] Cooling system: A cooling mechanism 13 (composed of an axial fan and a dust filter) is installed through one end of the charging box 1, and multiple sets of cooling holes 18 are opened at the other end. The cooling holes are designed with louvers to prevent rainwater from entering. The cooling mechanism is linked with the energy management module and automatically starts when the internal temperature exceeds 40°C. It dissipates the heat generated by the slip ring and cable joint during the charging process through air convection, ensuring that the equipment operates stably in high-temperature environments.
[0024] How to use and working principle of this device: Start-up identification: When the user brings the vehicle close to the charging box, the intelligent identification module 12 scans the vehicle's charging port or the user's QR code, automatically identifies the appropriate charging type (fast charging / slow charging), and transmits the signal to the energy management module 19; Cable release: The energy management module 19 sends a command to the cable winding and releasing mechanism 2 corresponding to the charging type. The variable speed motor 23 starts and drives the cable winding part to rotate through the rotating rod 24. The connecting cable 16 is released along the auxiliary cylinder 28. The limit sensor 25 on the rotating rod 24 detects the winding and releasing length in real time. When the preset value is reached, the motor is triggered to stop. The user can take out the slow charging gun 15 or fast charging gun 17 from the placement seat 14 and connect it to the vehicle. Charging control: After connection is completed, the user confirms the charging mode through the human-machine interface panel 11. The energy management module 19 links the photovoltaic storage system and adjusts the output power according to the energy storage status and photovoltaic power generation. The electric slip ring 29 ensures stable power transmission when the rotating rod 24 rotates, ensuring stable power supply for fast charging with high current or slow charging. Heat dissipation guarantee: During the charging process, the heat dissipation mechanism 13 is activated, forming air convection with the heat dissipation hole 18 at the other end of the charging box 1, which promptly removes the heat generated by components such as the slip ring 29 and the energy management module 19; End of winding: After charging is complete, the user removes the charging gun and puts it back on the placement seat 14. The energy management module 19 instructs the variable speed motor 23 to reverse, the rotating rod 24 retracts the cable, and the limit sensor 25 detects the end of winding and the motor stops, completing one charging cycle.
[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
