[0003] Currently, charging equipment on the market generally suffers from problems such as unreasonable layout, poor heat dissipation, and low assembly efficiency. Traditional charging cabinets typically adopt a centralized layout, leading to mutual interference between internal components, severe heat accumulation, and affecting the lifespan of the equipment. Furthermore, existing technologies often use cables to connect AC input and DC output units, which not only increases assembly complexity but also affects overall aesthetics and heat dissipation efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a layout structure for a charger, which solves the technical problems of poor heat dissipation performance and assembly efficiency caused by unreasonable internal layout of existing charger cabinets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a layout structure for a charger, including a cabinet, an AC input unit, a DC output unit, a control unit, an AC / DC conversion module, and a conductive assembly. The cabinet includes a front and a back panel opposite to each other. The control unit, the AC / DC conversion module, and the AC input unit are located on the front panel, and the DC output unit is located on the back panel. The control unit, the AC / DC conversion module, the AC input unit, and the DC output unit are electrically connected through the conductive assembly.

[0007] In one possible implementation, the cabinet has a first compartment, a second compartment, and a third compartment arranged sequentially from left to right. The control unit is located in the second compartment. The first compartment, the second compartment, and the third compartment are all equipped with the AC / DC conversion module, the conductor assembly, part of the AC input unit, and part of the DC output unit.

[0008] In one possible implementation, the layout structure further includes a molded case circuit breaker, an air switch assembly, and a surge protection assembly. The cabinet includes a live component area and a circuit component area. The AC input unit, the DC output unit, the control unit, and the AC / DC conversion module are all located in the live component area, while the molded case circuit breaker, air switch assembly, and surge protection assembly are all located in the circuit component area. The molded case circuit breaker, air switch assembly, and surge protection assembly are all electrically connected to the control unit via the conductive assembly.

[0009] In one possible implementation, the cabinet further includes three first cabinet doors covering the front of the cabinet and three second cabinet doors covering the back of the cabinet, wherein the three first cabinet doors correspond to the first compartment, the second compartment and the third compartment respectively, and the three second cabinet doors correspond to the first compartment, the second compartment and the third compartment respectively.

[0010] In one possible implementation, the first cabinet door has multiple air inlets, the second cabinet door has multiple air outlets, and a fan is provided at each of the air outlets.

[0011] In one possible implementation, the first cabinet door covering the second compartment is also provided with a control panel that is electrically connected to the control unit.

[0014] In one possible implementation, the front of the cabinet is provided with three magnetic door switches corresponding to the first cabinet door, and the back of the cabinet is provided with three magnetic door switches corresponding to the second cabinet door.

[0015] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model centrally arranges the control unit, AC / DC conversion module, and AC input unit on the front of the cabinet, facilitating front-side operation and wiring by operators; the DC output unit is independently located on the back of the cabinet, forming spatial isolation between input and output, which is beneficial for users to perform separate wiring operations for AC input and DC output; conductive components replace traditional cables as the core connection medium, and the electrical connection between various functional units is realized through a modular conductive structure. This design simplifies the complexity of internal wiring, improves assembly processability, and the overall layout, through the directional distribution of functional modules, constructs the shortest energy transmission path while ensuring electrical performance. At the same time, it reserves space for the subsequent air duct design of the heat dissipation system, making the layout structure of the charger more reasonable, thereby improving heat dissipation performance and assembly efficiency, and solving the technical problem of poor heat dissipation performance and assembly efficiency caused by unreasonable internal layout of existing charging cabinets.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0028] like Figure 1 and Figure 2As shown, this utility model provides a layout structure for a charger, including a cabinet 100, an AC input unit 201, a DC output unit 202, a control unit 203, an AC / DC conversion module 204, and a conductor assembly 205. The cabinet 100 includes a front and a back of the cabinet 100 arranged opposite each other. The control unit 203, the AC / DC conversion module 204, and the AC input unit 201 are disposed on the front of the cabinet 100, and the DC output unit 202 is disposed on the back of the cabinet 100. The control unit 203, the AC / DC conversion module 204, the AC input unit 201, and the DC output unit 202 are electrically connected through the conductor assembly 205.

[0029] Among them, the cabinet 100 refers to the frame structure used to accommodate various functional units. Specifically, it can be made of metal material by welding or assembly, and its front and back form a physical separation between the operation interface and the heat dissipation channel.

[0030] The AC input unit 201 refers to a device that connects to an external AC power source and performs primary processing. Specifically, it can be implemented by combining a terminal block and a filter circuit to receive and distribute input electrical energy.

[0031] The DC output unit 202 refers to the interface component that outputs the converted DC power to the load. Specifically, it can adopt a structure that combines copper busbars and insulating brackets for centralized management of the output ports.

[0032] The control unit 203 refers to the electronic module that monitors and regulates the charging process. Specifically, it can be an integrated PLC controller and signal acquisition circuit to coordinate the working status of each module.

[0033] AC / DC conversion module 204 refers to a power conversion device that converts alternating current (AC) to direct current (DC). Specifically, it can adopt a topology that combines IGBT power modules and transformers to realize the conversion of electrical energy form.

[0034] Conductor assembly 205 refers to a rigid conductive structure that replaces traditional cables. Specifically, it can be a busbar system that combines copper busbars and insulating support components, and achieves electrical connection between modules through preset installation positions.

[0035] The core innovation of this application lies in its design paradigm that combines a dual-zone layout on both the front and back sides with integrated conductor connections. By centrally arranging the control unit 203 and power module on the front to form an operation and maintenance area, while independently placing the output unit on the back to form a wiring isolation area, a topology of physical separation between input and output is constructed. Combined with conductor components 205 replacing discrete cables, a modular electrical connection architecture is formed, which shortens assembly time and reduces wiring consumption. This layout not only achieves functional zoning but also provides basic airflow space for front and rear convection ventilation and heat dissipation.

[0036] This layout design achieves separation of strong and weak current and physical isolation of input and output ports. The control unit 203, AC / DC conversion module 204, and AC input unit 201 are centrally located on the front of the cabinet 100, facilitating front-side operation and wiring by operators. The DC output unit 202 is independently located on the back of the cabinet 100, forming spatial isolation between input and output, which is beneficial for users to perform separate wiring operations for AC input and DC output.

[0037] Conductor assembly 205 replaces traditional cables as the core connection medium, achieving electrical connections between functional units through a modular conductive structure. This design simplifies internal wiring complexity and improves assembly manufacturability. The overall layout, through the directional distribution of functional modules, constructs the shortest energy transmission path while ensuring electrical performance, and simultaneously reserves space for the subsequent airflow design of the heat dissipation system.

[0038] See Figure 1 and Figure 2 Furthermore, the cabinet 100 is provided with a first compartment 103, a second compartment 104 and a third compartment 105 connected sequentially from left to right. The control unit 203 is located in the second compartment 104. The first compartment 103, the second compartment 104 and the third compartment 105 are each provided with an AC / DC conversion module 204, a conductor assembly 205, a partial AC input unit 201 and a partial DC output unit 202.

[0039] The horizontal three-compartment structure physically separates the cabinet 100 into three independent compartments (left, center, and right). Each compartment contains a complete AC / DC conversion module 204 and conductive components 205. Partial components of the AC input and DC output units are distributed across each compartment. The control unit 203 is centrally located in the second compartment 104, forming a symmetrical heat dissipation channel. The conductive components 205 employ a distributed connection method, replacing traditional cables to achieve electrical connections between compartments.

[0040] Specifically, the first compartment 103, the second compartment 104, and the third compartment 105 are horizontally separated to form independent heat dissipation areas. Heat generated by the AC / DC conversion module 204 within each compartment is exhausted through independent air ducts, preventing heat accumulation across compartments. The control unit 203, centrally located in the second compartment 104, allows it to directly monitor the operating parameters of the left and right compartments, such as temperature or current data, via the conductor assembly 205. The AC input unit is divided into three groups, each connected to one compartment, and the DC output unit is also deployed with three independent output ports, thus forming a modular power unit. The conductor assembly 205 uses a parallel topology to connect the input and output terminals of each compartment, for example, through copper busbars to achieve a low-impedance transmission path. The physical isolation between compartments allows maintenance to be performed on a single compartment; for example, in the event of a fault in the third compartment 105, only the conductor connection of that compartment needs to be disconnected for replacement, without requiring a complete system shutdown for overhaul.

[0041] This layout allows for the decentralized configuration of functional modules while maintaining the integrity of each compartment's function. Physical isolation between compartments helps reduce electromagnetic interference. The modular design facilitates assembly and independent maintenance. Distributed current transmission paths optimize the overall topology, avoiding the problems associated with centralized cable routing.

[0042] like Figure 1 and Figure 2 As shown, in one optional embodiment, the layout structure further includes a molded case circuit breaker 206, an air switch assembly 207, and a surge protection assembly 208. The cabinet 100 includes a live component area 106 and a circuit component area 107. The AC input unit 201, DC output unit 202, control unit 203, and AC / DC conversion module 204 are all located in the live component area 106, while the molded case circuit breaker 206, air switch assembly 207, and surge protection assembly 208 are all located in the circuit component area 107. The molded case circuit breaker 206, air switch assembly 207, and surge protection assembly 208 are all electrically connected to the control unit 203 via a conductor assembly 205.

[0043] The vertically layered layout separates the live component area 106 from the circuit component area 107. The live component area 106 includes an AC input unit 201, a DC output unit 202, a control unit 203, and an AC / DC conversion module 204. The circuit component area 107 centrally houses the molded case circuit breaker 206, the air switch assembly 207, and the surge protection assembly 208. A vertical connection channel is formed between the live component area 106 and the circuit component area 107 via a conductive assembly 205. The centralized arrangement of the circuit protection module physically isolates it from the control unit 203 to avoid electromagnetic interference.

[0044] The power modules are concentrated in the live component area 106, while the protection modules are concentrated in the circuit component area 107, forming physical isolation and avoiding cross-interference between lines. The vertical layout shortens the connection path of the conductor assembly 205, reducing cable redundancy. Simultaneously, it creates a natural heat dissipation channel between the upper and lower layers, reducing the thermal impact of high-power devices on the circuit protection components and improving system stability. Furthermore, the unified connection between the circuit protection module and the control unit 203 via the conductor assembly 205 simplifies the wiring process, improving assembly efficiency and maintenance convenience.

[0045] See Figure 3 and Figure 4 Furthermore, the cabinet 100 also includes three first cabinet doors 108 covering the front of the cabinet 100 and three second cabinet doors 109 covering the back of the cabinet 100. The three first cabinet doors 108 correspond to the first compartment 103, the second compartment 104 and the third compartment 105 respectively, and the three second cabinet doors 109 correspond to the first compartment 103, the second compartment 104 and the third compartment 105 respectively.

[0046] Each cabinet door can be opened and closed independently, facilitating operation on specific compartments. The cabinet doors are made of metal with a corrosion-resistant paint coating for enhanced durability. The first cabinet door 108 has ventilation holes for air intake and heat dissipation. The second cabinet door 109 is equipped with a fan to exhaust hot air. Insulation material can be installed on the inside of the cabinet doors to prevent accidental contact with live parts.

[0047] The compartmentalized cabinet door design optimizes internal airflow paths and improves heat dissipation. The independent door structure simplifies the assembly process, allowing each compartment module to be installed independently before its corresponding door is closed. Furthermore, this design enhances the security of the cabinet, reducing the risk of unauthorized personnel accessing internal components.

[0048] like Figure 3 and Figure 4 As shown, specifically, the first cabinet door 108 has multiple air inlets 1081, the second cabinet door 109 has multiple air outlets 1091, and a fan 111 is correspondingly installed at each air outlet 1091.

[0049] External cold air flows naturally into each compartment through the air inlet 1081 on the front cabinet door, forming the initial section of the heat dissipation airflow. Hot air inside the compartment is forced to flow along a preset path by the fan 111 and discharged through the air outlet 1091 on the rear cabinet door. Because the air inlets 1081 and outlets 1091 of the three compartments are spatially isolated, each compartment forms an independent circulating airflow path, preventing hot air cross-flow between adjacent compartments. When the temperature inside the compartment exceeds a set threshold, the exhaust volume can be increased by increasing the speed of the fan 111. This design ensures that the heat exhaust paths of each compartment do not interfere with each other, and simultaneously optimizes the balance between heat dissipation efficiency and energy consumption by dynamically adjusting the power of the fan 111.

[0050] The spatial separation design of the air inlet 1081 and air outlet 1091 avoids airflow short-circuiting, ensuring efficient heat dissipation from areas with concentrated electrical components. The placement of the fan 111 further enhances airflow efficiency, especially in high-power operation scenarios, dynamically adjusting heat dissipation intensity to prevent localized heat accumulation at the back of the cabinet 100. Furthermore, the distribution of the air inlet 1081 and air outlet 1091 is compatible with the compartmentalized structure, ensuring independent and non-interfering airflow paths within each compartment. This guarantees overall heat dissipation uniformity and avoids temperature rise issues caused by heat crosstalk between compartments. This heat dissipation design significantly improves the heat dissipation efficiency of the cabinet 100, effectively reduces the operating temperature of components, extends equipment lifespan, and enhances system operational stability.

[0051] See Figure 3 In one alternative embodiment, a control panel 209 electrically connected to the control unit 203 is also provided on the first cabinet door 108 that covers the second compartment 104.

[0052] The control panel 209 can integrate a touch screen or physical buttons, and transmit signals to the control unit 203 via a waterproof connector or shielded cable. A quick-connect interface can be provided between the control unit 203 and the cabinet door to facilitate the separation of the control panel 209 from the internal wiring during maintenance.

[0053] This design maintains the integrity of the heat dissipation duct while improving user convenience and safety. By reducing the need for frequent cabinet door openings, the risk of internal exposure is lowered, while maintaining the original heat dissipation efficiency. Furthermore, the optimized spatial layout separating the operating interface from the heat dissipation structure effectively resolves the conflict between user operation and heat dissipation needs, enhancing the overall user experience of the charger.

[0054] like Figure 5 and Figure 6 As shown, in one optional embodiment, the cabinet 100 is provided with a first sidewall 112 and a second sidewall 113 on opposite sides, and the first sidewall 112 and the second sidewall 113 are provided with a fan 111 control module and a sensor module 211.

[0055] The fan 111 control module and sensor module 211 are integrated into the two side walls of the cabinet 100, avoiding functional overlap with the live component area 106 and the circuit component area 107, thus optimizing space utilization. The fan 111 control module is located close to the air inlet and outlet 1091, reducing signal transmission loss and improving control response speed. The sensor modules 211 are distributed on both side walls, covering different areas inside the cabinet 100, comprehensively collecting environmental parameters. The modular design reduces wiring complexity, enhances the self-adaptive capability of the heat dissipation system, ensures uniform heat dissipation, avoids localized overheating, and improves heat dissipation efficiency and operational stability.

[0056] See Figure 1 Optionally, there are multiple molded case circuit breakers 206, which are symmetrically arranged in the circuit component area 107.

[0057] The symmetrical arrangement includes an axisymmetric distribution based on the geometric center line of the circuit component area 107 or a centrally symmetrical distribution based on a specific mounting point. The symmetrical layout forms a spatial correspondence with the conductive components 205 in the compartmentalized structure, so that the current path forms a balanced loop between the symmetrically distributed circuit breakers. At the same time, the convection path of the air inlet 1081 and the air outlet 1091 can cover the symmetrically arranged circuit breaker group, avoiding airflow obstruction in local areas.

[0058] Symmetrically arranged circuit breaker assemblies create equal-length current paths, reducing current drift caused by differences in line impedance. The symmetrical design of the maintenance windows allows operators to access both circuit breakers simultaneously, shortening the maintenance path. Mirror-arranged rails enable standardized installation, reducing the risk of assembly errors. Symmetrically distributed ventilation paths create balanced airflow circulation, preventing localized temperature buildup.

[0059] like Figure 1 As shown, in one optional embodiment, the front of the cabinet 100 is provided with three magnetic door switches 110 corresponding to the first cabinet door 108, and the back of the cabinet 100 is provided with three magnetic door switches 110 corresponding to the second cabinet door 109.

[0060] Each magnetic door switch 110 independently generates an open / closed status signal, which is transmitted via wire to the control unit 203 or the fan 111 control module on the side wall. When a compartment door is open, its corresponding magnetic door switch 110 triggers a signal interruption, and the control unit 203 can immediately locate the abnormal compartment and generate an alarm message. This detection mechanism works in conjunction with the conductive components 205 and heat dissipation ducts in the compartment layout. For example, when the door of the second compartment 104 is abnormally opened, the control unit 203 can cut off the power supply circuit of the conductor in that compartment and simultaneously shut down the operation of the corresponding fan 111. The symmetrical arrangement of the magnetic door switches 110 avoids the blind spots that may exist in traditional single detection devices. For example, the problem that the status of the back compartment cannot be monitored synchronously when only the front compartment door is detected is completely solved. Through a one-to-one correspondence, maintenance personnel can quickly identify abnormal compartments based on the magnetic door signals.

[0061] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
