[0063] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] like Figures 1 to 4 As shown, Figure 1 This is a schematic diagram of the structure of a combined module 100' in one embodiment of this application; Figure 2 for Figure 1 Another structural schematic diagram of the 100' modular module; Figure 3 for Figure 2 Exploded view of the 100' modular module; Figure 4 for Figure 1A schematic diagram of the structure of the 100' modular module after removing the cover plate.

[0065] The combined module 100' in this embodiment includes a functional module 100 and a sub-module 20. The functional module 100 includes a first housing 101 and a first circuit board assembly 107 with a first function located within the first housing 101. Specifically, the first circuit board assembly 107 may include a circuit board 1071 and various electronic devices disposed on the circuit board 1071. These electronic devices may be, for example, capacitors, chips, semiconductor power devices, etc. The electronic devices may be, for example, independent devices soldered onto the circuit board 1071, or devices integrated onto the circuit board 107. Furthermore, the first function mentioned in this embodiment refers to the ability of the first circuit board assembly 107 to perform a first function. For example, if the first function is a charging function, then the first circuit board assembly 107 includes various hardware components capable of performing the charging function. These hardware components are connected for the purpose of performing the first function, and these connections include electrical connections, signal connections, etc.

[0066] The sub-module 20 of the modular module 100' includes a second housing 201 and a hardware unit group 204 located within the second housing 201. The first housing 101 and the second housing 201 are detachably connected. The first circuit board assembly 107 and the hardware unit group 204 can be connected and combined to form a second circuit board assembly with a second function. Here, the hardware unit group 204 of the sub-module 20 does not need to have an independent function; that is, the hardware unit group 204 may include some hardware that implements a certain function. After this part of the hardware is connected to the first circuit board assembly 107 of the functional module 100, it can be combined to form a second circuit board assembly with an independent second function. In other words, the hardware of the sub-module 20 and at least some of the hardware of the functional module 100 are connected for the purpose of realizing a second function. This connection includes electrical connections, signal connections, etc. The hardware can be electrical devices or circuit boards. The hardware unit group 204 may include only electronic devices or a combination of circuit boards and electrical devices. The first circuit board assembly 107 can be a whole and the hardware unit group 204 of the sub-module 20 connected together to form the second circuit board assembly, or a part of the first circuit board assembly 107 and the hardware unit group 204 of the sub-module 20 connected together to form the second circuit board assembly. A part of the first circuit board assembly 107 can be some electronic components of the first circuit board assembly 107, or it can be a part of the circuit board and some electronic components.

[0067] In some embodiments, the individual hardware unit group 204 may also have independent functions, and the embodiments of this application do not impose specific limitations.

[0068] It can be seen that the first circuit board assembly 107 of the functional module 100 and the second circuit board assembly that implements the second function overlap. For example, the second circuit board assembly that implements the second function may require M hardware components, while the first circuit board assembly 107 that implements the first function has N hardware components. However, P (P≤N) of the N hardware components overlap with some of the hardware components in the second circuit board assembly. Therefore, the sub-module 20 only needs to set (MP) hardware components. When the second function needs to be implemented, it is only necessary to connect the sub-module 20 and the functional module 100 to form a combined module 100' that includes M hardware components and has the second function. It can be seen that the setting of the sub-module 20 allows the functional module 100 to be expanded into a module with the second function in a relatively simple way. It is equivalent to the module with the first function and the module with the second function sharing a part of the hardware and a part of the casing.

[0069] The modular module 100' can have only the second function, or it can retain the first function, meaning the modular module 100' has both the first and second functions. In this case, if the modules with the first and second functions were set up separately, (M+N) hardware units would be required. However, according to this embodiment, only (N+MP) hardware units are needed in total. It can be seen that both functions can be achieved with fewer hardware units.

[0070] In some embodiments, the first circuit board assembly 107 can perform functions such as charging, and the second circuit board assembly can perform functions such as optical storage. Of course, the second circuit board assembly can have both charging and optical storage functions.

[0071] like Figures 5 to 8 As shown, Figure 5 for Figure 4 A structural diagram from another perspective; Figure 6 for Figure 5 Enlarged diagram of part A in the middle; Figure 7 for Figure 4 Another structural diagram from a different perspective. Figure 7 Further electronic components of the first circuit board assembly 107 are shown; Figure 8 for Figure 7 Top view.

[0072] In this example, the functional module 100 is a charging module, and the combined module 100' includes an optical storage module. The circuit board 1071, capacitors, and other devices of the first circuit board assembly 107 of the charging module are also hardware required by the optical storage module. Therefore, the sub-module 20 can be equipped with hardware such as the contactor 2041 that is required by the optical storage module but not by the charging module. After the functional module 100 and the sub-module 20 are combined together, an optical storage module with optical storage function is formed. That is, the optical storage module and the functional module 100 share some hardware.

[0073] In some embodiments, the functional module 100 is not limited to a charging module, and the combined module 100' is not limited to including a photovoltaic storage module, but can also be other combined forms, such as a combination of a high-voltage module and a low-voltage module.

[0074] Therefore, the embodiments of this application can have the following technical effects:

[0075] Firstly, by setting up sub-modules 20 that can be combined with functional modules 100, functional modules 100 with the first function can be expanded into second modules with the second function, thereby expanding the hardware installation space, meeting the module layout methods of different functions, reducing the product development cycle, improving design efficiency, and reducing costs.

[0076] Secondly, the functional module 100 and the sub-module 20 are detachable, which facilitates quick switching between different modules and reduces design costs. That is, when the first function is needed, the sub-module 20 is detached, and when the second function is needed, the sub-module 20 is connected.

[0077] Thirdly, in this embodiment, the sub-module 20 can be connected to any position in the functional module 100 according to actual functional requirements, satisfying the diverse needs of module design. Of course, regardless of where the sub-module 20 is connected in the functional module 100, its hardware unit group 204 and the first circuit board assembly 107 can be connected to form the second circuit board assembly.

[0078] Please continue to combine Figure 3 In this embodiment, the combined module 100' includes a connector 30. The first circuit board assembly 107 of the functional module 100 and the hardware unit group 204 of the sub-module 20 are specifically connected through the connector 30. This facilitates the connection between the first circuit board assembly 107 and the hardware unit group 204 after the first housing 101 and the second housing 201 are assembled and connected.

[0079] See again Figure 9 and Figure 10 , Figure 9 for Figure 3 A structural schematic diagram of the functional module 100 of the combined module 100'; Figure 10 for Figure 9 Enlarged diagram of part B in the middle.

[0080] like Figure 10 As shown, the first housing 101 may have an opening 101a, and one end of the connector 30 may pass through the opening 101a and be connected to the first circuit board assembly 107. The first circuit board assembly 107 may be provided with a functional interface, which can be used for power switching and signal connection. The functional interface of the first circuit board assembly 107 may be defined as a first functional interface 1072 (shown in...). Figure 6The connector 30 passes through the opening 101a and can be connected to the first functional interface 1072 of the first circuit board assembly 107. The other end of the connector 30 is connected to the hardware unit group 204, which also has a functional interface, which can be defined as the second functional interface 2042 (shown in...). Figure 8 The other end of connector 30 is connected to the second functional interface 2042 of hardware unit group 204.

[0081] Please refer to Figures 11 to 13 , Figure 11 for Figure 3 A schematic diagram of the connection between the intermediate functional module 100 and the adapter 302 of the connector 30; Figure 12 for Figure 11 An explosion diagram; Figure 13 for Figure 12 Enlarged diagram of part C in the middle.

[0082] In this embodiment, as Figure 3 As shown, the connector 30 specifically includes an adapter 302 and a connecting copper busbar 301. A portion of the adapter 302 can pass through the opening 101a and connect to the first functional interface 1072 within the first housing 101. The adapter 302 may have connecting holes for connection with the connecting holes 101a around the opening 101a on the first housing 101 via fasteners, such as screws. The adapter 302 may also have connecting posts, and the end of the connecting copper busbar 301 may have insertion holes. The connecting posts are inserted into the insertion holes to connect the connecting copper busbar 301 and the adapter 302. Separating the connector 30 into the adapter 302 and the connecting copper busbar 301 facilitates the manufacturing of the connector 30 and the connection operations with the first circuit board assembly 107 and the hardware unit group 204.

[0083] In a specific example, the first housing 101 has a first sidewall 10111 with the aforementioned opening 101a. One side of the second housing 201 is open, and the first sidewall 10111 covers the opening. By making one side of the sub-module 20 open, it can be directly attached to the first sidewall 10111 of the first housing 101 for connection. This reduces the amount of housing material used and facilitates the accommodation and concealment of the connector 30, protecting the connector 30. It also makes the assembled modular module 100' have a relatively flat appearance.

[0084] like Figure 2 and Figure 3As shown, the first shell 101 is a cuboid structure with one sidewall called the first sidewall 10111. The second shell 201 is also a cuboid structure, with its open side having a shape and size that is basically the same as the first sidewall 10111. Thus, the first shell 101 and the second shell 201 can be directly assembled into a larger cuboid structure. Of course, the first shell 101 and the second shell 201 can be either cuboids or cubes. Relatively regular shell structures will maintain their relatively regular shape after assembly, which is beneficial for spatial arrangement.

[0085] like Figure 14 As shown, Figure 14 for Figure 1 A schematic diagram of the structure of part of the housing of the middle functional module 100 and the sub-module 20.

[0086] Figure 14 In this design, the second housing 201 includes an annular edge portion 20111 surrounding the opening, defining the opening. The annular edge portion 20111 connects to other sidewalls of the adjacent second housing 201. The annular edge portion 20111 of the second housing 201 connects to the edge portion of the first sidewall 10111 of the first housing 101. That is, one side of the second housing 201 is not completely open, retaining an annular edge portion 20111. The annular edge portion 20111 and the first sidewall 10111 of the first housing 101 are positioned opposite each other. This facilitates the connection between the annular edge portion 20111 and the first sidewall 10111 of the first housing 101 when assembling the first housing 101 and the second housing 201, resulting in a smoother appearance of the assembled housing. For example, the annular edge portion 20111 and the first sidewall 10111 can both be provided with connecting holes. Figure 14 The connecting hole 201a shown allows for connection and fixation via fasteners such as screws.

[0087] In a specific embodiment, the modular module 100' may include a first annular sealing gasket 40, such as Figure 12 , 13 As shown, the first annular sealing gasket 40 surrounds the opening 101a, and a portion of the connector 30 is inserted into the opening 101a, with the portion of the connector 30 abutting against the first annular sealing gasket 40. Specifically, a portion of the adapter 302 is inserted into the opening 101a, and the portion of the adapter 302 abuts against the first annular sealing gasket 40. The first annular sealing gasket 40 improves the airtightness of the connection between the adapter 302 and the first housing 101, meeting protection requirements. The first housing 101, the first annular sealing gasket 40, and the adapter 302 can all be provided with connection holes for connection using fasteners such as screws. Figure 10 The connection hole 101a shown is provided on the first housing 101.

[0088] In the above embodiments, the first housing 101 and the second housing 201 can be detachably connected by at least one of the following connection methods: plug-in connection, or connection by fasteners.

[0089] like Figure 15 As shown, Figure 15 for Figure 1 A schematic diagram of the structure in which the central functional module 100 and the sub-module 20 are connected by the first connection method.

[0090] As described above, both the annular edge portion 20111 and the first sidewall 10111 are provided with connection holes, thereby allowing connection via fasteners such as screws. The functional module 100 and sub-module 20 are defined to be distributed and spliced ​​along a first direction, i.e., the first direction is... Figure 4 , 5 The left and right directions shown can also be used to define a second direction and a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. The second direction is... Figure 4 , 5 The vertical direction, the third direction, that is... Figure 4 , 5 In the front-back direction, connection holes can be provided at the upper and lower positions of the annular edge portion 20111. Of course, connection holes can also be provided at positions distributed along a third direction. In addition, the connection holes in the first sidewall 10111 can also be set as blind holes to reduce communication with the internal space of the first housing 101.

[0091] Let's look again. Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of the structure in which the functional module 100 and the sub-module 20 are connected by a second connection method in an embodiment of this application. Figure 17 for Figure 16 Enlarged schematic diagram of part D in the middle.

[0092] Functional module 100 and sub-module 20 can be connected using a combination of fastener connections and plug-in connections. For example... Figure 17 As shown, the first housing 101 is provided with a hook, and the second housing 201 is provided with a hanging hole. During assembly, the hook and the hanging hole can be plugged in first, that is, the hook is inserted into the hanging hole, which can pre-position the first housing 101 and the second housing 201. Then, the fasteners are inserted into the connecting holes of the first housing 101 and the second housing 201 to achieve fixation. This combination connection method can improve the assembly efficiency.

[0093] As can be seen, the connection between functional module 100 and sub-module 20 is diverse, using fasteners such as screws and pins, which provides good convenience.

[0094] like Figure 2 ,4 and Figure 5 As shown, in a specific embodiment, the functional module 100 may have a first output port 102 and a first input port 103. The sub-module 20 is provided with a second input port 203 and a second output port 202. After the sub-module 20 and the functional module 100 are combined into a combined module 100', the second input port 203 and the second output port 202 are the input and output ports of the combined module 100'.

[0095] The first output port 102, the first input port 103, and the second output port 202 and the second input port 203 can be located on the same side of the modular module 100', which facilitates connection with external devices. Figure 4 and Figure 5 As shown, for the specific structure of the functional module 100, the second direction can be defined as the front-to-back direction. The functional interface, first input port 103, and first output port 102 of the functional module 100 are all located on the front side, while the functional interface of the hardware unit group 204 is located on the rear side. In this case, in order to allow the second input port 203 and the second output port 202 to also be located on the same side, the connecting copper busbar 301 is relatively long, extending along the second direction to the rear side to connect with the reserved second functional interface 2042 of the hardware unit group 204. The second input port 203 and the second output port 202 can then be arranged on the front side. The hardware unit group 204 can also include a connecting copper busbar 2043, which extends along the second direction to connect to the second input port 203 and the second output port 202 on the front side. Of course, the functional interface of the hardware unit group 204 does not necessarily have to be arranged in the opposite direction to the second input port 203 and the second output port 202. Multiple input and output ports can be arranged according to actual needs, and the first circuit board assembly 107 and the hardware unit group 204 can also be adaptively adjusted in position.

[0096] like Figure 18 As shown, Figure 18 for Figure 1 An exploded view of the modular module 100'.

[0097] In a specific embodiment, both the first housing 101 and the second housing 201 can be separately provided with cover plates. Specifically, the first housing 101 may include a first housing body 1011 and a first cover plate 1012, and the second housing 201 may include a second housing body 2011 and a second cover plate 2012. Both the first housing body 1011 and the second housing body 2011 can have an opening on one side. Figure 18In the example of the orientation, there are openings at the top of both, with the first cover plate 1012 and the second cover plate 2012 respectively covering the corresponding openings. It can be seen that the openings can also be set in other positions, and the first cover plate 1012 and the second cover plate 2012 can be set in other positions accordingly. The first cover plate 1012 and the second cover plate 2012 can serve as the entire sidewall of the corresponding shell, or as a part of a sidewall, depending on actual needs.

[0098] This design facilitates the maintenance and replacement of the hardware inside the first housing 101 and the second housing 201. Furthermore, when assembling the first housing 101 and the second housing 201, the first cover plate 1012 can be removed for easier connection via fasteners.

[0099] You can continue to refer to this. Figures 19 to 20 , Figure 19 This is a schematic diagram of the structure of a functional module 100 in an embodiment of this application; Figure 20 This is an exploded view of functional module 100 of the 19 types.

[0100] As described in the above embodiments, the functional module 100 includes a first housing 101 and a first circuit board assembly 107 located within the first housing 101. The first circuit board assembly 107 has a first function and a functional interface, defined as a first functional interface 1072. The functional interface of the first circuit board assembly 107 is used to connect with a corresponding sub-module 20 to form a second circuit board assembly with a second function. In other words, the functional module 100 is an independent module capable of implementing the first function and can be used independently.

[0101] To facilitate connection and expansion with sub-module 20, the first housing 101 of functional module 100 has an opening 101a, which corresponds to the first functional interface 1072 of the first circuit board assembly 107. Here, correspondence means that the connector 30 can connect to the first functional interface 1072 of the first circuit board assembly 107 after passing through the opening 101a.

[0102] Functional module 100 is not limited to setting one functional interface. For example, it can set more functional interfaces. Each functional interface and its corresponding sub-module 20 are combined to form a module with a new function that is different from the first function.

[0103] In a specific embodiment, the functional module 100 may include a handle 106 disposed on the first housing 101 to facilitate operation of the functional module 100, such as carrying or transporting.

[0104] For reference Figure 21 As shown, Figure 21 for Figure 20Enlarged diagram of part E in the middle.

[0105] At this time, the functional module 100 may also include a second annular sealing gasket 105 and a sealing plate 104. The second annular sealing gasket 105 is arranged around the opening 101a, and the sealing plate 104 presses against the sealing gasket and seals the opening 101a. In this way, when it is not necessary to expand into a combined module 100' with a second function, the opening 101a can be sealed by the second annular sealing gasket 105 and the sealing plate 104 to maintain the airtight performance of the first housing 101 and meet the protection requirements. Both the second annular sealing gasket 105 and the sealing plate 104 may be provided with connection holes to allow for connection and fixation to the first housing 101 by fasteners such as screws.

[0106] like Figure 22 As shown, Figure 22 This is a schematic diagram of the structure of a sub-module 20 in an embodiment of this application.

[0107] This application embodiment also provides a sub-module 20, which includes a second housing 201 and a hardware unit group 204, the hardware unit group 204 being located within the second housing 201; the hardware unit group 204 has a functional interface, which is used to connect with a corresponding functional module 100 to form a second circuit board assembly with a second function. As mentioned above, the sub-module 20 may not be an independent module, that is, it does not have a usable function when not combined with the functional module 100, and forms a combined module 100' with a second function after being combined with the functional module 100; of course, the sub-module 20 may also be an independent module with a function.

[0108] like Figure 4 and Figure 5 As shown, in a specific embodiment, the combined module 100' is an optical storage module. In this case, the sub-module 20 is provided with a contactor 2041 and a circuit board. This circuit board is a smaller circuit board than the circuit board 1071 in the functional module 100, that is, it is smaller in size and the number of devices on it can also be set to be relatively small.

[0109] This embodiment also provides a charging energy storage system, which may include at least one functional module 100 as described in the above embodiments and at least one sub-module 20 as described in the above embodiments, wherein at least one functional module 100 is a charging module, and at least one charging module and the corresponding sub-module 20 are combined to form a combined module 100' with a second circuit board assembly.

[0110] The charging energy storage system may include, for example, a charging station. The charging station can be equipped with multiple functional modules 100, such as S functional modules 100. Depending on actual usage, if the number of charging modules is found to be redundant, some functional modules 100 and sub-modules 20 can be combined to form a combined module 100' that includes a photovoltaic and energy storage module. For example, S1 functional modules 100 and their corresponding sub-modules 20 can be combined, in which case (S-S1) functional modules 100 can be retained for continued use as charging modules, while S1 combined modules 100' including photovoltaic and energy storage modules are created. The charging energy storage system may also include an energy storage device. The combined module 100' can be connected to the energy storage device, and its photovoltaic and energy storage function can store the converted electrical energy in the energy storage device. This provides the charging energy storage system with high flexibility, allowing for the allocation of charging and energy storage according to actual needs.

[0111] like Figures 23 to 25 As shown, Figure 23 This is a structural block diagram of a charging energy storage system under a first operating condition according to an embodiment of this application; Figure 24 for Figure 23 A structural block diagram of a medium-capacity energy storage system under the second operating condition; Figure 25 for Figure 23 The structural block diagram of the charging energy storage system under the third operating condition.

[0112] In a specific embodiment, the functional module has a first input port 103 and a first output port 102. The first input port 103 can be connected to the power grid, and the first output port 102 can be connected to electrical equipment, such as a new energy vehicle. The sub-module has a second input port 203 and a second output port 202. The second input port 203 can be connected to an energy harvesting device, such as a photovoltaic harvesting system or a wind power generation system. The harvested energy can be converted into electrical energy and stored in an energy storage device through a photovoltaic-storage module.

[0113] As an example, the combined module 100' can have both the first and second functions, namely, both charging and energy storage functions.

[0114] At this time, as Figure 23 As shown, when the electrical equipment needs electricity, it is connected to the first output port 102. Electrical energy from the power grid is input through the first input port 103, processed by the first circuit board assembly, and then output to the electrical equipment through the first output port 102. An energy harvesting device is connected to the second input port 203, and after processing by the second circuit board assembly, it is output to the energy storage device through the second output port 202 for energy storage.

[0115] like Figure 24As shown, when electrical equipment needs electricity but the power grid has sufficient power, the power grid can also output energy to the energy storage device through the first input port 103 and after being processed by the second circuit board assembly, through the second output port 202 for energy storage.

[0116] like Figure 25 As shown, when the electrical equipment needs electricity but the power grid is insufficient, the energy harvesting device can output to the electrical equipment through the first output port 102 after being processed by the second circuit board assembly through the second input port 203. That is, the energy harvesting device and the power grid work together to charge the electrical equipment.

[0117] As can be seen, the combined module 100' in this embodiment enables the charging and energy storage systems to be interconnected, forming multiple working modes to adapt to different working conditions.

It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
