Description

Technical Field

[0001] Embodiments of the present disclosure generally relate to the technical field of charging cabinets, and more particularly to an integrated box for a charging cabinet and a charging cabinet. Background Art

[0002] Charging cabinets are mainly used in public places, residential areas, commercial areas and highway service stations, and can provide energy supply services for electric vehicles. By efficiently converting grid electricity into the DC power required by vehicle batteries, vehicle batteries can be safely and quickly charged, effectively solving the range anxiety of electric vehicles and promoting the development of green travel. In conventional charging cabinets, a multi-module design is often used to improve the service capacity of the charging cabinet. Each charging cabinet includes multiple PDMs (Power Distribution Modules). Each PDM module works independently or collaboratively to assume functions such as power conversion, charging control and fault protection. However, when a single PDM module fails, the existing maintenance method often requires all PDM modules and the overall installation structure inside the charging cabinet to be disassembled in order to replace or repair the faulty module. The disassembly process is time-consuming, which significantly reduces the availability and maintenance efficiency of the charging cabinet. Utility Model Content

[0040] The preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc. may refer to different or the same objects.

[0042] As mentioned above, in conventional charging cabinets, a multi-module design is often used to improve the service capacity of the charging cabinet. Each charging cabinet includes multiple PDMs (Power Distribution Modules). Each PDM module works independently or collaboratively to undertake functions such as power conversion, charging control, and fault protection. However, when a single PDM module fails, the existing maintenance method often requires that all PDM modules and the overall installation structure inside the charging cabinet be disassembled in order to replace or repair the faulty module. The disassembly process is time-consuming, which significantly reduces the availability and maintenance efficiency of the charging cabinet.

[0043] The embodiments of the present disclosure provide an integrated box 100 for a charging cabinet and a charging cabinet. In the integrated box 100, each of the multiple supporting plates 21 is detachably coupled to the box body 10, and can be operated to be inserted into or pulled out of the box body 10 through the opening 101. When any power distribution module 23 in the integrated box 100 fails, the supporting plate 21 carrying the power distribution module 23 can be removed from the box body 10, and then the box body 10 can be pulled out along the opening 101. When removing the faulty power distribution module 23, it is only necessary to remove the connection between the corresponding power distribution module 23 and the busbar and quickly remove the related cables, which significantly reduces the required disassembly workload. The following will be combined with Figures 1 to 13 To describe the principles of the present disclosure in detail.

[0044] like Figure 1 and Figure 2As shown, the integrated box 100 for the charging cabinet includes a box body 10 and a plurality of bearing plates 21. The box body 10 can be a square / rectangular box body 10, which can be suitable for most standard installation environments, such as embedded, wall-mounted or floor-standing types. Of course, non-standard shapes can also be customized according to the installation location and usage scenarios, such as concealed distribution boxes or other combined shapes with curved surfaces that fit the wall. The box body 10 can be made of cold-rolled steel plates (SPCC), stainless steel plates, aluminum alloy profiles, and engineering plastics. The box body 10 is provided with an opening 101 on its first side. The first side generally refers to a main surface of the box body 10, such as the front side of the box body 10. The opening 101 allows the operator to directly access the electrical equipment inside the box body 10 through this entrance, and can perform installation, maintenance or replacement operations. An avoidance gap 121 is provided on a pair of second side portions (i.e., opposite sides) of the box body 10. The avoidance notch 121 can provide a passage for the busbar 30 to penetrate, so that the busbar 30 can enter the inside of the box body 10 from the outside of the box body 10 without being blocked, thereby achieving effective connection with internal components.

[0045] The busbar 30 plays a core role in power transmission in the charging cabinet and may be one or more main power lines. Figure 1 and Figure 2 As shown, the busbar 30 may include a plurality of copper bars arranged in parallel.

[0046] like Figure 1 and Figure 2 As shown, a plurality of carrier plates 21 are placed in parallel inside the housing 10, and each carrier plate 21 is designed to carry one or more power distribution modules 23. Each power distribution module 23 can be electrically connected to the busbar 30 independently, and can be responsible for a portion of the processing or distribution of electrical energy. In the embodiment of the present disclosure, the plurality of carrier plates 21 are detachably coupled to the housing 10, that is, each of the plurality of carrier plates 21 can be quickly installed or removed as needed.

[0047] The operator can insert or pull out the carrier plate 21 into or out of the box body 10 through the opening 101 on the first side of the box body 10, so as to flexibly increase, decrease, replace or maintain the internal power distribution module 23. With this arrangement, when any power distribution module 23 in the integrated box 100 fails, the carrier plate 21 carrying the power distribution module 23 can be removed from the box body 10, and then the box body 10 can be pulled out along the opening 101. When removing the faulty power distribution module 23, only the corresponding carrier plate 21 is removed, and the disassembly workload is small. At the same time, when removing the faulty power distribution module 23, it will not affect the normal operation of other power distribution modules 23, thereby improving the charging efficiency and facilitating the use of users.

[0048] In some embodiments, Figure 3and Figure 4 As shown, the box body 10 includes a bottom plate 11, a connector 13, a support beam 14 and two side plates 12. The two side plates 12 are arranged side by side on both sides of the bottom plate 11 to form the above-mentioned pair of second side portions, and the two side plates 12 are coupled to the bottom plate 11. An avoidance notch 121 is formed at the top position of the two side plates 12, and the busbar 30 can be inserted into the inside of the box body 10 along the top of the two side plates 12, and then electrically connected to a plurality of power distribution modules 23 respectively. The connector 13 is arranged on the rear side of the bottom plate 11 and the two side plates 12 away from the opening 101, and the connector 13 is coupled to the bottom plate 11 and the two side plates 12. In other words, the connector 13 can be a back plate, which is used to block or shield the rear side of the box body 10. The support beam 14 is disposed at the front side of the two side plates 12 and coupled to the two side plates 12 to form the aforementioned opening 101 for taking and placing the carrying plate 21 between the support beam 14 , the bottom plate 11 and the two side plates 12 .

[0049] like Figure 3 and Figure 4 As shown, the bottom plate 11 is the base part of the box body 10. The two side plates 12 are arranged side by side on both sides of the bottom plate 11, and together constitute the two side walls of the box body 10, that is, the pair of second side parts referred to above. In some embodiments, the bottom plate 11 and the two side plates 12 can be formed by stamping and bending the same metal part. In some alternative embodiments, the two side plates 12 can also be tightly combined with the bottom plate 11 by coupling, and the coupling here can be welding, bolt connection, snap connection, etc.

[0050] As mentioned above, an escape notch 121 is formed at the top of the two side panels 12. The escape notch 121 allows the busbar 30 to directly penetrate into the interior of the box body 10 from the top of the box body 10 in a horizontal direction without being blocked by the side panels 12, which facilitates the access and wiring of the busbar 30. After the busbar 30 enters the interior of the box body 10 along the escape notch 121 at the top of the side panel 12, it can be electrically connected to the multiple power distribution modules 23 in the box body 10 to form an effective power distribution system. The support beam 14 is arranged on the front side of the two side panels 12 (i.e., the side close to the opening 101) and is coupled to the two side panels 12. The support beam 14 can strengthen the structural strength of the box body 10, and can also be used to support and fix the internal load-bearing plate 21 or install other electrical components to ensure that the box body 10 remains stable during operation.

[0051] In the embodiment of the present disclosure, the main structure of the box body 10 is constructed by the bottom plate 11 , the side plates 12 , the connecting members 13 and the supporting beams 14 , and an opening 101 is formed between the bottom plate 11 , the supporting beams 14 and the two side plates 12 .

[0052] In some embodiments, Figures 1 to 4As shown, the bottom plate 11 includes a plurality of slide rails 111 arranged in parallel, and the plurality of slide rails 111 can provide guidance for the sliding of the plurality of bearing plates 21 in the box body 10 .

[0053] like Figures 1 to 4 As shown, a plurality of slide rails 111 are arranged on the bottom plate 11 along the same direction, and the plurality of slide rails 111 are adjacent to each other but do not cross each other. Each slide rail 111 is an independent guide device, which is used to support and guide the carrier plate 21 to make a linear motion in the box body 10 when the carrier plate 21 is inserted into or withdrawn from the box body 10 along the opening 101.

[0054] In some embodiments, Figures 1 to 4 As shown, a plurality of slide rails 111 are formed by stamping and bending. In this process, a suitable metal sheet is selected as the bottom plate 11, and pressure is applied to the bottom plate 11 by a precise stamping die and equipment to cause plastic deformation, thereby bending it into a slide rail 111 of a desired shape and size according to a predetermined design profile. After stamping and bending, the slide rail 111 has a precise straight line segment, which can provide a stable guide for the carrier plate 21, ensuring that the carrier plate 21 slides smoothly along the expected trajectory in the box body 10.

[0055] In some alternative embodiments, multiple independent slide rails 111 can also be coupled to the base plate 11 by appropriate means such as welding, fastener connection, etc. In this case, the slide rail 111 can be a slide groove type slide rail 111, a roller type slide rail 111, a steel ball type slide rail 111, a gear type slide rail 111, etc.

[0056] In some embodiments, Figure 2 and Figure 8 As shown, the box body 10 further includes an insulating cover plate 15 , which is disposed on a side (ie, a top side) of the two side plates 12 that is away from the bottom plate 11 .

[0057] The insulating cover 15 helps to cover the power distribution module 23 and the busbar 30 inside the box 10, and can provide a physical barrier and electrical isolation, while also helping to maintain the cleanliness inside the box 10, preventing dust and other impurities from entering the electrical area, and ensuring the normal operation of electrical equipment. At the same time, the insulating cover 15 can prevent current leakage or short circuit accidents from occurring, and can protect the safety of workers.

[0058] In some embodiments, Figure 3 , Figure 4 and Figure 5 As shown, the connecting member 13 is provided with a through hole 131 , and the through hole 131 can allow a cable to pass through.

[0059] like Figure 3 , Figure 4 and Figure 5As shown, the connector 13 is provided with a through hole 131. With the above arrangement, an opening 101 is provided on the front side of the box body 10, and a through hole 131 is provided on the rear side of the box body 10, and both the opening 101 and the through hole 131 can allow cables to pass through. The power distribution module 23 is not only electrically connected to the busbar 30, but also electrically connected to the data line and the power line. The data line is used for data transmission and circuit control, and the power line is used to provide power to the charging device. In an embodiment of the present disclosure, the opening 101 allows one of the data line and the power line to pass through, and the through hole 131 allows one of the data line and the power line to pass through.

[0060] The advantages of arranging data lines and power lines separately are as follows: First, the data lines are responsible for transmitting digital signals and have high requirements for signal integrity. If the power lines and data lines are too close or share the same path, the AC ripple and electromagnetic interference (EMI) in the power lines may couple to the data lines, causing data transmission errors or reduced rates. Separate settings can physically isolate the power lines and data lines, reduce the mutual influence of electrical noise, and improve the stability and reliability of data transmission.

[0061] Secondly, the power supply line can focus on providing stable DC power to the load without taking into account the data transmission function. This can make the power supply system more concise and efficient, facilitate the targeted implementation of power management measures such as filtering and voltage stabilization, ensure that pure and compliant power is provided to sensitive electronic equipment, help extend the life of the equipment, and prevent equipment failures caused by power problems.

[0062] Then, when the power line and the data line are separated, if there is a power supply problem (such as insufficient power supply, power fluctuation, etc.) or a data transmission problem (such as communication interruption, data loss, etc.), since the two do not affect each other, the fault location will be more direct, which speeds up the fault diagnosis and repair process.

[0063] Again, separating high-voltage / high-current power lines from low-voltage, low-current data lines can effectively reduce safety risks caused by unexpected situations such as short circuits and leakage, and protect users and equipment from hazards such as electric shock or fire.

[0064] Finally, for devices that require multiple power supply modes or data interfaces, separate power and data lines means that one can be replaced or upgraded independently without affecting the function of the other. For example, the power distribution module 23 may need to be upgraded to a faster data transmission standard, or replaced with a power line that adapts to a different power supply environment. In this case, separate arrangement makes such changes more convenient.

[0065] In addition, and more importantly, the data line and the power line are coupled to the power distribution module through a quick-release method, which can further improve efficiency and stability when the power distribution module is disassembled. In addition, the quick-release modules of the data line and the power line are equipped with a fool-proof design to prevent the risk of wrong insertion and improve reliability.

[0066] In some embodiments, Figure 3 , Figure 4 and Figure 6 As shown, the two side plates 12 further include a bending portion 122. The bending portion 122 is disposed on one side of the two side plates 12 facing the insulating cover plate 15, so as to be suitable for being detachably coupled to the insulating cover plate 15.

[0067] like Figure 3 , Figure 4 and Figure 6 As shown, the two side panels 12 each further include a bending portion 122, and the bending portion 122 can be obtained by bending the top edge of the side panel 12. The bending portion 122 is located on the side of the side panel 12 facing the insulating cover plate 15, and when the side panel 12 and the insulating cover plate 15 are assembled together, the bending portion 122 is in direct contact with the insulating cover plate 15. The bending portion 122 can be detachably connected to the insulating cover plate 15, and the insulating cover plate 15 can be removed from the side panel 12 or installed to the side panel 12 as needed. The coupling method includes but is not limited to screw fastening, snap connection, plug-in interface, etc. The shape, size and surface features (such as slots, threaded holes, flanges, etc.) of the bending portion 122 should match the corresponding structure on the insulating cover plate 15 to ensure that the two can be tightly and stably combined, while being easy to disassemble and maintain. With the above arrangement, the bent portion 122 can be detachably coupled to the insulating cover plate 15, thereby ensuring the overall packaging and protection requirements of the box body 10, while ensuring the convenience of assembly and maintenance operations.

[0068] In some embodiments, Figure 6 and Figure 7 As shown, the integrated box 100 further includes an insulating member 22 . The insulating member 22 is disposed on a side of the carrier plate 21 facing the power distribution module 23 .

[0069] like Figure 6 and Figure 7As shown, the integrated box 100 is also equipped with an insulating member 22. The main function of the insulating member 22 is to provide electrical isolation, thereby ensuring equipment safety, preventing short circuits, and maintaining signal purity. The insulating member 22 is coupled to the side of the carrier plate 21 close to the power distribution module 23. In other words, the insulating member 22 is located between the carrier plate 21 and the power distribution module 23. With this arrangement, when the power distribution module 23 is working, the high voltage and high current generated by it will not be transmitted to other low-voltage, sensitive electronic equipment in the box 10 through abnormal channels, or cause the risk of electric shock to personnel. The insulating member 22 can be directly attached to the carrier plate 21, or fixed in a designated position by means of a bracket, a buckle, etc., to ensure its stable and reliable isolation effect inside the integrated box 100.

[0070] In some embodiments, Figure 7 As shown, the bearing plate 21 includes a front flange 211, a rear flange 212 and a bottom flange 213. The front flange 211 is detachably coupled to the support beam 14 and the bottom plate 11. The rear flange 212 is detachably coupled to the connecting member 13. The bottom flange 213 is slidably connected to the slide rail 111, and the bottom flange 213 abuts against the bottom plate 11.

[0071] like Figure 7 As shown, the edge portion of the carrier plate 21 is formed into three different flanges by stamping and bending. A flange refers to an edge portion formed by extending outward or inward along a direction perpendicular to the plate surface. The flange can be used to enhance the structural strength of the carrier plate 21, provide an additional installation interface, or dock with other components. The front flange 211 is located at the front edge of the carrier plate 21, the rear flange 212 is located at the rear edge of the carrier plate 21, and the bottom flange 213 is located at the bottom edge of the carrier plate 21.

[0072] The front flange 211 is connected to the support beam 14 and the bottom plate 11 in a detachable manner. The connection between the front flange 211 and the support beam 14 and the bottom plate 11 is reversible, and can be easily installed or removed without destroying the original structure. The coupling method can include bolt connection, snap connection, pin connection, etc. The rear flange 212 is connected to the connecting member 13 in a detachable coupling manner. The rear flange 212 is removed from the connecting member 13, and the load-bearing plate 21 can be pulled out along the opening 101.

[0073] The bottom flange 213 is connected to the slide rail 111 by sliding, and the carrier plate 21 can smoothly move along a predetermined track on the slide rail 111 to achieve position adjustment. At the same time, the bottom flange 213 always keeps in contact or closely abuts against the bottom plate 11 during the sliding process, ensuring the stability of the carrier plate 21 during the sliding process and preventing shaking or deviation.

[0074] In some embodiments, Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, the connecting member 13 is provided with a plurality of positioning holes 132 , and the rear flange 212 and the bottom flange 213 both include a connecting portion 214 formed by bending, and the connecting portion 214 is suitable for being inserted into the positioning hole 132 , thereby realizing the positioning of the carrying plate 21 .

[0075] like Figure 4 , Figure 5 and Figure 7 As shown, a plurality of positioning holes 132 are provided on the connecting member 13, and the plurality of positioning holes 132 can be divided into a plurality of rows and a plurality of columns. A connecting portion 214 formed by bending is provided on the rear flange 212, and a connecting portion 214 formed by bending is also provided on the bottom flange 213. With this arrangement, when the carrying plate 21 is inserted into the box body 10 along the opening 101, the plurality of connecting portions 214 on the rear side of each carrying plate 21 can be inserted into the plurality of positioning holes 132 one by one, so that the rear side of the carrying plate 21 can be positioned and fixed.

[0076] In some embodiments, Figure 5 As shown, in order to further increase the stability of the load-bearing plate 21, on the rear side, the connecting portion 214 can be connected to the bottom plate 11 or the connecting member 13 by bolts, pins, etc. On the front side (i.e., the opening side), the connecting portion 214 can be connected to the support beam 14 and the bottom plate 11 by bolts, pins, etc.

[0077] In some embodiments, Figure 7 As shown, a notch 215 is provided on both the front flange 211 and the rear flange 212, and the size of the notch 215 is related to the number and size of cables that need to pass through.

The pair of integrated boxes 100 are arranged in the cabinet body 400 and coupled to the cabinet body 400.

[0081] like Fig.12 and Fig.13 As shown, the charging cabinet is a device for centralized storage and charging of various electronic devices (such as electric vehicles, etc.), usually with a certain capacity, safety protection function and management control system. The cabinet 400 includes but is not limited to components such as a shell, door panels, vents, handles, locks, and legs. The cabinet 400 not only provides protection for internal electronic components and charging units, but also undertakes the functions of overall structural strength, appearance, heat dissipation, fire prevention, dust prevention, and anti-theft. A pair of integrated boxes 100 are arranged in the cabinet 400, and the pair of integrated boxes 100 are coupled to the cabinet 400. The two integrated boxes 100 are responsible for converting the input AC power into DC power suitable for charging, and can realize intelligent monitoring, scheduling and safety management of the charging process.

[0082] In some embodiments, Fig.12 and Fig.13 As shown, one of the pair of integrated boxes 100 is suitable for connecting to the positive pole of the power supply, and the other is suitable for connecting to the negative pole of the power supply. One of the pair of integrated boxes 100 can be electrically connected to the positive pole of the external power supply through a dedicated interface, a terminal block or a connecting cable. The other of the pair of integrated boxes 100 can be electrically connected to the negative pole of the power supply. The negative pole of the power supply has a lower potential in the circuit and forms a complete power supply circuit together with the positive pole. When the pair of integrated boxes 100 are connected to the positive and negative poles of the power supply, respectively, they can receive electrical energy from the bus 30 and convert it into a DC voltage suitable for the charging device. The power distribution module 23 inside the integrated box 100 manages the charging process according to the charging requirements of the device, such as battery type, charging protocol, etc., to ensure that the device is charged safely and efficiently. With this arrangement, a complete charging circuit is formed after the charging interface is connected to the device to be charged. The current flows in this closed loop, realizing the effective transmission of electrical energy from the power supply to the device battery.

[0083] In some embodiments, Fig.12 and Fig.13As shown, a bracket 410 is also provided in the charging cabinet. The bracket 410 can provide stable and reliable support for the integrated box 100, ensuring that the integrated box 100 has a reasonable layout and runs smoothly. The bracket 410 can be selected from brackets 410 of different materials, structures, and shapes according to different design requirements, load-bearing capacity, space utilization efficiency, and other factors. For example, through metal profiles (such as aluminum profiles, steel) brackets, plastic brackets, composite brackets, etc., as well as customized modular brackets, folding brackets, sliding brackets, etc. The bracket 410 is arranged inside the cabinet 400 of the charging cabinet and can be fixed at a specific position (such as the back, bottom or both sides) of the cabinet 400. The compactness, heat dissipation efficiency, and convenience of operation and maintenance of the integrated box 100 are ensured through a reasonable layout. The bracket 410 can ensure that the integrated box 100 will not be displaced due to its own weight or the vibration generated by the operation of internal components during operation, and maintain its fixed position inside the cabinet 400 to ensure the normal operation of the charging function.

[0084] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
