Description

Technical Field

[0001] The utility model relates to the technical field of charging pile power distribution, in particular to a multi-way switch module. Background Art

[0002] With the global adoption of sustainable energy and environmentally friendly mobility, electric vehicle sales have experienced explosive growth over the past decade, directly driving the rapid development of the charging infrastructure industry. As a key enabler for the widespread adoption of electric vehicles, efficient and convenient charging services have become a focus of industry attention. However, as electric vehicles continue to increase their charging efficiency requirements, charging infrastructure must possess higher power density and flexible scalability to meet the growing demand. Against this backdrop, the electrical architecture design of charging facilities faces significant challenges, particularly in achieving efficient and reliable power distribution and switching, which has become a key bottleneck restricting the performance improvement of charging facilities.

[0003] Given the limitations of these technologies, switch module technology has emerged. The electrical connections between circuits can be designed as a modular structure, with power switching achieved through switch modules, making them one of the core components of charging facilities. Currently, charging facilities on the market generally use a design approach where high-voltage switch components are discretely installed or simply stacked. While this traditional architecture can meet basic charging needs, it is inadequate for advanced applications such as high power density and multi-circuit parallel charging. First, the limited internal space of the charging cabinet makes the layout and heat dissipation of high-voltage switch components challenging. Second, the complex electrical connections between charging circuits not only increase the risk of system failure but also make installation and maintenance more difficult. Crucially, the contactor components in traditional designs often fail to form independent functional modules, making rapid replacement and upgrades difficult, making it difficult to meet the future trend of intelligent and modular charging facilities.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of this utility model without substantially changing the technical content.

[0034] like Figures 1 to 7 As shown, this embodiment provides a multi-way switch module 110, which includes a control board 44, a contactor group 33, and an input and output wiring group 22; the control board 44 is arranged adjacent to the contactor group 33 and is electrically connected via a cable; the contactor group 33 includes a first contactor group 332 close to the control board 44 and a second contactor group 331 away from the control board 44, the first contactor group 332 and the second contactor group 331 are electrically connected via a copper busbar, and the first contactor group 332 and the second contactor group 331 each include a plurality of contactors 333 of the same number, the plurality of contactors 333 in the first contactor group 332 are electrically connected via a copper busbar, and the plurality of contactors 333 in the second contactor group 331 are not connected to each other; the input and output wiring group 22 includes an input wiring copper busbar group 221 and an output wiring copper busbar group 222, the first contactor group 332 is electrically connected to the input wiring copper busbar group 221, and the second contactor group 331 is electrically connected to the output wiring copper busbar group 222.

[0035] Specifically, the incoming wiring copper bar group 221 includes a plurality of incoming wiring copper bars 2211, the outgoing wiring copper bar group 222 includes a plurality of outgoing wiring copper bars 2221, each contactor 333 in the first contactor group 332 is electrically connected to one incoming wiring copper bar 2211, and each contactor 333 in the second contactor group 331 is electrically connected to one outgoing wiring copper bar 2221. It should be noted that the multi-way switch module 110 of this embodiment can be configured with a specific number of inputs and outputs according to actual needs, without specific limitation. In actual applications, a four-way, five-way, or six-way input and output type is preferably used.

[0036] The control board 44 communicates with the external system. In this embodiment, the control board 44 communicates with the charging device, such as the main control board of the charging station, and is responsible for receiving commands and transmitting status information. The first contactor group 332 is in a connected state, forming a closed circuit path. By controlling the number of closed contactors 333 in the first contactor group 332, the current flowing through the circuit is adjusted, thereby controlling the output power. For example, when a higher power output is required, more contactors 333 can be closed; when a lower power output is required, the number of closed contactors 333 is reduced. When the circuit needs to be closed, the charging device sends a signal to the multi-way switch module 110, closing some or all of the contactors 333 in the second contactor group 331, thereby forming a path with the outgoing wiring busbar 2221. Current flows from the incoming wiring busbar 2211 through the first contactor group 332 and the second contactor group 331 (which are now partially or fully closed), to the outgoing wiring busbar 2221, ultimately supplying the load. When the circuit needs to be disconnected, the charging device sends a signal to open the closed contactor 333 in the second contactor group 331, thereby cutting off the current path and achieving circuit disconnection.

[0037] To specifically illustrate the charging mode of this embodiment, Figure 7 As shown, this is a schematic diagram of a charging mode of this embodiment. The multi-way switch module 110 acts on the charging pile 90, and the power supply 10 inputs multiple voltages to the charging pile 90. The current passing through the first contactor group 332 is adjusted to control the output power, and then the power is output to different loads through the second contactor group 331. In this embodiment, the load is preferably an electric car 100. It should be noted that, according to different needs, the output voltage of the charging pile 90 is 220V and 380V. The input voltage of the AC (220V) charging pile power supply 10 is single-phase 220VAC, the output is AC, and the output power is single-phase 220V / 5KW; the input voltage of the DC (380V) charging pile power supply 10 is three-phase four-wire 380VAC, and the output is DC. The voltage input by the power supply 10 and different types of charging piles 90 can be set according to actual needs, and no specific restrictions are made here.

[0038] The multi-way switch module 110 of this embodiment adopts a highly integrated multi-way intelligent switch array design, achieving seamless communication with the main control board of the charging device, accurately issuing customized switch control instructions, and uploading the specific working status of each switch in real time, realizing dynamic and efficient power distribution and adjustment strategies, significantly improving charging efficiency and energy utilization; the highly integrated independent components and detection system are not only compact in structure and beautiful in layout, but also ensure the logic and clarity of the internal structure, making the installation process simple and fast, achieving cost-effective manufacturing, while taking into account the convenience of subsequent maintenance and overhaul, so that faulty or outdated contactors can be quickly replaced without interrupting the operation of other circuits, significantly reducing maintenance costs and time; the multi-way switch module 110 of this embodiment is used for charging equipment with multiple outputs, adapting to various complex charging needs. The internal functional modules are clearly divided, not only meeting the stringent requirements of large-capacity charging equipment, but also providing a solid foundation for large-scale production and deployment. The modularization also greatly improves its reliability and maintainability.

[0039] In order to realize the communication between the multi-way switch module 110 and the main control board of the charging device and the control of the internal contactor group 33, as shown in FIG. Figure 1 、 Figure 6 and Figure 9 As shown, in one specific embodiment, the control board 44 includes a CAN communication interface with CAN communication functionality and a communication connector 441 with a detection function. The CAN communication interface is located on the side of the control board 44 away from the contactor group 33, and the communication connector 441 is located on the side of the control board 44 closer to the contactor group 33. The input and output wiring assembly 22 also includes power terminals 224 and communication terminals 223. The power terminals 224 are connected to the CAN communication interface and are connected to the outside via a cable to access the low-voltage control power supply 60. The communication terminals 223 are also connected to the CAN communication interface and are connected to the outside via a cable. They communicate with the main control board of the charging device using CAN communication to receive and transmit the operating status of each contactor 333.

[0040] Specifically, the CAN communication interface is located on a side of the control board 44 away from the contactor group 33 , facilitating access to the power connection terminal 224 and the communication connection terminal 223 , and is located at the front end of the entire multi-way switch module 110 .

[0041] Furthermore, if Figures 1 to 2As shown, each contactor 333 is provided with a first communication point 3311, a second communication point 3312, a first power supply point 3313, and a second power supply point 3314, each of which is connected to the communication connector 441 of the control board 44 via a cable. The communication connector 441 can also detect the status of the communication point of the contactor 333, allowing the control board 44 to accurately know the current status of each contactor 333 and perform corresponding operations or protection actions to avoid signal loss, interruption, etc. The communication connector 441 is located on the side of the control board 44 close to the contactor group 33, which facilitates cable connection and ensures that the length of each cable group is consistent. The cable layout is beautiful and neat, saving space in the multi-way switch module 110.

[0042] like Figures 2 to 5 As shown, the multi-way bridging and expansion of the multi-way switch module 110 of this embodiment is specifically described using five input and output channels. Specifically, the first contactor group 332 and the second contactor group 331 each consist of ten contactors 333. The first contactor group 332 and the second contactor group 331 are arranged in two regular rows from the direction close to the control board 44 to the direction away from the control board 44, with five contactors 333 in each row. The contactors 333 in the first contactor group 332 are connected via a first connecting copper bar 3321, a second connecting copper bar 3322, a third connecting copper bar 3323, a fourth connecting copper bar 3324, a fifth connecting copper bar 3325, and an inter-contactor connecting copper bar 3326. The first contactor group 332 is connected to the second contactor group 331 via an inter-contactor group connecting copper bar 3327, a third connecting copper bar 3323, and an incoming wiring copper bar 2211, respectively. The third connecting copper bar 3323 connects the first contactor group 332 to the second contactor group 331 and also connects the contactors 333 between the first contactor group 332. The incoming wiring copper bar 2211 connects the incoming wiring copper bar group 221 to the outside world and also connects the first contactor group 332 to the second contactor group 331.

[0043] like Figures 1 to 2 and Figure 6 As shown, to provide physical protection and electrical isolation for the multi-way switch module 110 and ensure safe operation of the module, in one specific embodiment, the multi-way switch module 110 further includes a housing assembly 11. The housing assembly 11 is provided with a housing space consisting of a housing frame 111 and a rear panel to accommodate the control board 44 and the contactor assembly 33. The rear panel is provided with copper busbar holes to allow the incoming copper busbar assembly 221 and the outgoing copper busbar assembly 222 to extend from the housing space and be connected to the outside via cables. Preferably, the rear panel is a rear insulating plate 113.

[0044] Specifically, the ten contactors 333 in the first contactor group 332 are all connected to the ten incoming copper busbars 2211 in the incoming copper busbar group 221, and the ten contactors 333 in the second contactor group 331 are all connected to the ten outgoing copper busbars 2221 in the outgoing copper busbar group 222. The rear insulating plate 113 is provided with twenty corresponding copper busbar holes for the incoming and outgoing copper busbars. At the same time, the insulation setting of the rear panel prevents the incoming copper busbar group 221 and the outgoing copper busbar group 222 from damaging the multi-way switch module 110 due to the material of the rear panel when in operation. It should be noted that the housing frame 111 is formed by bending sheet metal. The sheet metal can be bent into complex and stable geometric shapes, which enhances the mechanical strength and stability of the housing frame 111. At the same time, the cost is relatively low, which helps to reduce the overall manufacturing cost.

[0045] Furthermore, if Figures 1 to 6 As shown, the shell frame 111 includes a U-shaped base 1111, an upper cover 1112 and a front panel 1113. The control board 44 is fixed to the inner side of the front panel 1113 and can be fixed to the front panel 1113 by rivet screws, that is, the control board 44 is fixed between the front panel 1113 and the contactor group 33. The U-shaped base 1111 is provided with an insulating column and a raising bracket. The insulating column is used to support the contactor group 33, and the raising bracket is used to raise the contactor 333 to a preset required height.

[0046] In this embodiment, the U-shaped base 1111 is composed of two left and right panels and a bottom panel. It can be formed by bending a single sheet of metal directly into a U-shape, or by assembling three sheets of metal together, depending on actual needs. To ensure an aesthetically pleasing wiring layout and facilitate the entry and exit of the incoming and outgoing copper busbars 221 and 222 from the housing assembly 11, the first contactor assembly 332 is positioned higher than the second contactor assembly 331. Two insulating posts are provided, namely the first insulating post 114 and the second insulating post 115; two raising brackets are provided, namely the first raising bracket 1114 and the second raising bracket 1115.

[0047] Specifically, the two rows of ten contactors 333 in the first contactor group 332 are all mounted on the first elevated bracket 1114, staggered front-to-back and left-to-right from the control panel 44 to the control panel 44 to conserve internal space. The first elevated bracket 1114 is directly mounted on the third connecting copper busbar 3323, which is mounted on the first insulating column 114 on the bottom panel of the U-shaped base 1111. This elevates and supports the first contactor group 332 while also preventing direct contact between the third connecting copper busbar 3323 and the bottom panel, which could cause damage during operation. The front panel 1113 also includes openings for exposing the power supply terminals 224 and the communication terminals 223.

[0048] The vertical projection of the second insulating pillar 115 overlaps with the first insulating pillar 114, supporting a portion of the incoming wiring busbar 2211 and the inter-contactor group connecting busbar 3327. The five contactors 333 in the second contactor group 331, located near the control board 44, are directly fixed to the bottom panel. The five contactors 333 in the row away from the control board 44 are mounted on the second elevated bracket 1115 on the bottom panel, with a front-to-back staggered arrangement. The highest point of the first contactor group 332 is higher than the highest point of the second contactor group 331.

[0049] The multi-way switch module 110 in this embodiment will generate a lot of heat during operation. In order to prevent the excessive heat from affecting the module, the multi-way switch module 110 needs to be cooled. Figure 1 and Figure 6 As shown, in a specific embodiment that can be implemented, a ventilation area 116 is provided on the left and right panels, the bottom panel, and the upper cover 1112 of the U-shaped base 1111, and a plurality of ventilation holes with regular or irregular patterns are provided in the ventilation area 116. Preferably, the ventilation area 116 in this embodiment is a long strip of ventilation holes. Alternatively, the ventilation area 116 is provided with an angled heat sink, or a heat sink is also provided. As long as the heat dissipation function can be achieved, there is no specific limitation here. Furthermore, insulating barley paper is also provided on the U-shaped base 1111 and the upper cover 1112 to ensure the safety of the multi-way switch module 110 when a large current passes through.

[0050] In order to facilitate the practical application of the multi-way switch module 110, in a specific example that can be implemented, a handle 112 is provided on the outside of the front panel 1113. Preferably, a handle 112 is provided at both ends of the outside of the front panel 1113. The handles 112 are fixed to the left and right panels of the U-shaped base 1111 through the mounting holes on the front panel 1113, and are symmetrically arranged. The provision of the handles 112 facilitates the push-pull installation of the multi-way switch. The front panel 1113 is sprayed with a universal color, and silk screen printing is added according to the functions on the control panel 44, so that the meaning expressed by the control panel 44 can be clearly identified, realizing a human-machine interface. An indicator light is provided on the side of the control panel 44 away from the contactor group 33. The indicator light includes an operation indicator light and an alarm indicator light, so that the working status of the multi-way switch module 110 can be observed.

[0051] like Figures 8 and 9FIG. 1 shows a schematic diagram of a multi-way switch module 110 according to this embodiment. The multi-way switch module 110 includes ten switches 80 in a first contactor group 332, ten switches 80 in a second contactor group 331, and a switch control and monitoring unit 50. The ten switches 80 in the first contactor group 332 connect the ten contactors 333 in the first contactor group 332, forming a closed circuit path. By controlling the number of closed switches 80 in the first contactor group 332, the current flowing through the circuit can be adjusted, thereby controlling the output power. The ten switches 80 in the second contactor group 331 have their inputs connected to the 1DC1+ interface, 1DC1- interface, 2DC1+ interface, 2DC1- interface, ..., 5DC1+ interface, and 5DC1- interface, respectively, through the first contactor group 332. Their outputs are connected to the 1DC2+ interface, 1DC2- interface, 2DC2+ interface, 2DC2- interface, ..., 5DC2+ interface, and 5DC2- interface, respectively. In this embodiment, the 1DC1+ interface, 1DC1- interface, 2DC1+ interface, 2DC1- interface...5DC1+ interface, 5DC1- interface are respectively located on the incoming wiring copper busbar group 221, that is, the ten incoming wiring copper busbars 2211; the 1DC2+ interface, 1DC2- interface, 2DC2+ interface, 2DC2- interface...5DC2+ interface, 5DC2- interface are respectively located on the outgoing wiring copper busbar group 222, that is, the ten outgoing wiring copper busbars 2221.

[0052] like Figure 9 and Figure 6 As shown, the switch control and monitoring unit 50 is also connected to the low-voltage control power supply 60 and the communication unit 70, and forms a secondary circuit with the first contactor group 332 and the second contactor group 331, thereby realizing remote control and remote signaling of the multi-way switch module 110. It should be noted here that the switch control and monitoring unit 50 is located on the control board 44, the low-voltage control power supply 60 is located on the power terminal 224, and the communication unit 70 is located on the communication terminal 223. In this example, the low-voltage control power supply 60 is preferably a +12V low-voltage control power supply 60, and the communication unit 70 is preferably the main control board of the charging device.

[0053] In this embodiment, the incoming wiring copper busbar group 221 inputs five groups of DC input signals 1DC1+ and 1DC1-, 2DC1+ and 2DC1-...5DC1+ and 5DC1- to the contactor group 33, and outputs five groups of DC output signals 1DC2+ and 1DC2-, 2DC2+ and 2DC2-...5DC2+ and 5DC2- through the contactor group 33. The control board 44 is connected to the power supply terminal 224 so that the switch control and monitoring unit 50 is connected to the +12V low-voltage control power supply 60. The control board 44 is connected to the communication unit 70 so that the switch control and monitoring unit 50 is connected to its main control board. The switch control and monitoring unit 50 sends control instructions to the contactor group 33 according to demand, and uploads the switch working status, and adjusts the current passing through the circuit in the first contactor group 332, thereby controlling the output power.
