Description

Technical Field

[0001] This utility model relates to the field of structural design technology, specifically to a dual-gun charging pile. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the demand for AC charging piles, a key energy replenishment facility, is increasing daily. Currently, most mainstream AC charging piles on the market adopt a single-gun design with a single charging interface, making it difficult to cope with peak demand from users charging at concentrated times, thus limiting equipment utilization efficiency and operational benefits.

[0003] Furthermore, existing charging piles generally suffer from the following shortcomings in structural design: First, the internal layout of the pile lacks modularity and symmetry, resulting in cumbersome production and assembly processes, making it difficult to achieve pre-assembly and mass production on assembly lines, thus hindering production efficiency and increasing manufacturing costs. Second, the installation methods of charging piles (such as wall-mounted and column-mounted) often adopt independent design schemes, resulting in poor structural compatibility between the pile and the column. Converting the installation requires replacing parts or redesigning, which not only increases material and installation costs but also leads to a lack of overall cohesion and aesthetics in the appearance of the entire pile, affecting the overall image of the charging station.

[0004] Therefore, there is an urgent need in this field for an AC charging pile solution that can support simultaneous charging of two charging guns, has a modular internal structure, and can flexibly adapt to different installation methods, in order to solve the comprehensive problems of existing technologies in terms of charging efficiency, production economy and structural adaptability.

Detailed Implementation

[0024] As a crucial energy replenishment facility for new energy vehicles, the demand for AC charging stations is increasing daily. However, existing charging stations generally suffer from the following shortcomings: The lack of modular and symmetrical design in the internal layout of the pile body leads to complicated production and assembly processes, making it difficult to achieve pre-assembly and mass production on assembly lines. The charging piles are installed using an independent design scheme, and the structural compatibility between the pile body and the column is poor. Converting the installation requires replacing parts or redesigning.

[0025] Therefore, there is an urgent need in this field for an AC charging pile solution that can support simultaneous charging by two guns, in order to solve the technical problem that the utilization efficiency of existing AC charging piles is limited due to the use of a single gun design.

[0026] Based on the above background, this utility model proposes a dual-gun charging pile structure. Through a modular mounting frame, it achieves pre-assembly and rapid final assembly of core components, significantly improving production efficiency and reducing costs. The cabinet adopts a functional partition design. The dual charging gun sockets on the first panel support simultaneous charging of two vehicles, improving equipment utilization. The second and third panels are respectively equipped with cable inlets and operating structures, ensuring neat wiring and operational safety. This design balances the rationality of the internal layout with the convenience of external use, effectively solving the problems of poor compatibility and low efficiency of traditional charging piles.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 The image shows a specific embodiment of the dual-gun charging station provided by this utility model, comprising: A dual-gun charging station, characterized in that it includes a cabinet 2 and a modular mounting frame 3 installed inside the cabinet 2; The cabinet 2 includes a first panel, a second panel and a third panel; the first panel is provided with two charging gun holders 102, the second panel is provided with a cable inlet, and the third panel is provided with an operating structure. The modular mounting bracket 3 includes a modular mounting bracket 3011 and a control structure, an operation structure, a display structure, a power grid input structure, and a handover control structure. Each structure is electrically connected to the others and is mounted on the modular mounting bracket 3011, which is installed in the cabinet 2.

[0032] In this specific embodiment, the cabinet and modular mounting frame together constitute the core physical architecture of the dual-gun charging pile. The cabinet achieves clear functional zoning through its first, second, and third panels: the two charging gun sockets centrally located on the first panel provide a physical interface for simultaneous dual-gun charging, directly improving the service capability and utilization efficiency of the equipment; the dedicated cable inlet on the second panel ensures the standardized introduction of the power grid input cable, which is beneficial for ensuring electrical safety and simplifying on-site installation; the integrated operation structure on the third panel provides users with a centralized and convenient human-machine interface.

[0033] The modular mounting rack, serving as the structural carrier for core electrical functions, integrates control, operation, display, power grid input, and traffic control structures into a single unit. This highly integrated modular design allows all electrical structures to be pre-installed and internally wired outside the cabinet, forming a complete functional module. This module is then installed as a whole inside the cabinet. This structural form transforms complex on-site cabinet assembly into efficient modular final assembly, greatly simplifying the final assembly process, ensuring product consistency and reliability, and providing significant convenience for production, testing, and subsequent maintenance.

[0034] The functional zoning layout of the cabinet and the integrated design of the modular mounting rack work together to achieve the technical benefits of the dual-gun charging pile in terms of clear external functions, compact internal structure, and efficient production and assembly.

[0035] In another specific embodiment of this utility model, the cabinet body 2 is connected to the cabinet door panel 1, as shown in the reference.

The communication antenna 201 provides communication functionality for the cabinet 2, the sealing cover 203 provides a waterproof seal when wall-mounted, and the silicone sealant 204 provides a seal when wall-mounted, reducing the impact of dust and other contaminants on the components inside the cabinet.

[0037] Reference Figure 2 As shown in (b), two charging gun holders 102 are arranged side by side at the bottom of the first panel. The first panel also includes a screen display component 101 located above the charging gun holders 102 and charging indicator lights 103 located on both sides of the charging gun holders 102. The screen display component 101, the charging gun holders 102, and the charging indicator lights 103 are all fixed to the cabinet door panel 1 with screws. Reference Figure 2 As shown in (c), the inlets include an electrical grid inlet 208, a gun wire inlet 207, and a communication wire inlet 209, which are sequentially arranged on the bottom surface of the cabinet 2. The operating structure includes an emergency stop button 206 and a door lock 205, both of which are located on the side of the cabinet 2. The door lock 205 provides security and anti-theft protection for the cabinet 2. In an emergency, pressing the emergency stop button 206 can quickly cut off the circuit inside the cabinet to prevent danger. The electrical grid inlet 208, the gun wire inlet 207, and the communication wire inlet 209 satisfy the input / output and external communication functions of the cabinet 2.

[0038] Reference Figure 2 As shown in (d), the cabinet 2 is also equipped with an auxiliary structure, including a wall-mounting screw mounting port 2011 on the back of the cabinet 2, providing mounting holes for wall-mounting screws to enable the wall-mounting function of the dual-gun charging pile. In this specific embodiment, the back of the cabinet 2 is also equipped with a cabinet heat dissipation hole 2010 and an anti-theft screw hole 2012. The cabinet heat dissipation hole 2010 provides ventilation and heat dissipation for the cabinet 2, preventing problems such as excessive internal temperature causing derating of the charging pile output. The anti-theft screw hole 2012 is fixed to the mounting component from inside the cabinet 2 with screws to prevent the charging pile from being disassembled from the outside, thus serving an anti-theft function. A meter window 2013 is also provided on the side of the cabinet 2 to meet various metering display functions.

[0039] The modular mounting component 3 supports the installation of all components inside the cabinet 2 and consists of three main parts: a galvanized steel plate mounting bracket 306, a router mounting bracket 309, and a modular mounting bracket 3011, providing installation positions for the electrical components inside the cabinet 2. The modular mounting bracket 3011 has a symmetrical structure, as shown in the reference...

The display area is symmetrically arranged on both sides of the operation area, and the handover control area is symmetrically arranged on both sides of the power grid input area.

[0040] Reference Figure 4 As shown, the router mounting bracket 309 is mounted on the modular mounting bracket 3011, and the galvanized steel plate mounting bracket 3010 is mounted on the router mounting bracket 309. The modular mounting bracket 3011 is fixed to the welded beam inside the cabinet 2 by screws. The whole is a sheet metal structure, formed by bending and stamping. The modular mounting bracket 3011 adopts a modular assembly design. After all components are assembled, the connector is left outside, and the whole assembly can be completed at one time, which is simple and efficient. Alternatively, it can be pre-assembled during production, which is called pre-assembly processing. It can be mass-produced on the assembly line, and then assembled with the cabinet 2. Then, the wire harness and other components are plugged in and connected to achieve cost reduction and efficiency improvement.

[0041] The control structure includes a first control board 307 and a second control board 3010, which are sequentially mounted in the control area via brackets. The control area also includes a router 308 and a galvanized steel plate 305. The second control board 3010 is directly mounted on a modular mounting bracket 3011. The router 308 is mounted on the outside of the second control board 3010 via a router mounting bracket 309. The first control board 307 is mounted on the outside of the router 308. The galvanized steel plate mounting bracket 306 has sufficient space to accommodate both the router 308 and the first control board 307 while being connected to the router mounting bracket 309. The galvanized steel plate 305 is mounted on the outside of the first control board 307 via the galvanized steel plate mounting bracket 306. In this specific embodiment, the galvanized steel plate 305 is an electrolytically galvanized steel plate.

[0042] The control structure includes a residual current device 3012 mounted in the control area via a residual current device mounting bracket 301101 and an air switch 304 mounted in the control area via an air switch mounting bracket 301102.

Each AC contactor 303 is also individually connected to a control module 301. In this specific embodiment, the control module 301 is a PME module.

[0043] The dual-gun charging pile structure provided by this utility model also considers situations where wall mounting is not possible, and pre-drilled installation holes are provided. When the charging pile 4 needs to be fitted with a base, the cabinet 2 and the support column 5 can be connected by screws through the pre-drilled installation holes inside the charging pile 4. The end of the support column 5 furthest from the cabinet 2 is installed on the ground, making operation convenient. (Refer to...) Figure 5 As shown, Figure 5 (a) is a sectional view of the side of the cabinet 2 and the column 5 during installation. Figure 5 (b) is a front sectional view of the installation of cabinet 2 and column 5. Figure 5 (c) in the diagram is a simplified side connection diagram of the cabinet and the upright. Figure 5 (d) shows a simplified diagram of the front connection between the cabinet and the column. There are two fixing screws in the front view, six fixing screws in the top view, and four fixing screws in the side view. The fixing positions can be referenced in the connection diagram. The overall fixing points form a triangle, connecting cabinet 2 and column 5 into a single unit from three directions, improving the overall aesthetics and uniformity. In the overall system design, each of the two branch circuits is equipped with an air switch 304, a leakage current protector 3012, an AC meter 3013, and an AC contactor 303, effectively enhancing the protection mechanism of each branch circuit. If any branch circuit experiences a short circuit or open circuit, the other branch circuit can still provide charging service. Additionally, an external emergency stop button provides a second line of defense for the overall safety of the unit. The entire system control terminal uses CAN and RS485 communication to achieve internal and external control, ensuring timely and effective control.

[0044] This utility model, through its dual-gun design, can simultaneously charge two electric vehicles, significantly improving the operational efficiency and output allocation flexibility of a single charging station, and helping to reduce operating costs. Structurally, it adopts a modular assembly scheme, achieving a symmetrical layout within the cabinet. Core electrical components can be pre-assembled on mounting racks to form independent functional modules before being fully installed into the cabinet. This design transforms complex on-site assembly into efficient modular assembly, greatly improving production efficiency and reducing production costs. Furthermore, through a rational structural design, it achieves rapid compatibility and stable integration between the charging station cabinet 2 and the column 5, satisfying the convenient conversion between wall-mounted and column-mounted installation methods while enhancing the overall uniformity and aesthetics of the charging station. This design not only enhances the product's market competitiveness but also optimizes the convenience of maintenance operations, contributing to a better overall image for operators.
