Integrated designs also require increasingly larger enclosures, which are prone to defects during the casting process, increasing production costs. Furthermore, fault repairs often require complete replacement or complex maintenance, increasing maintenance complexity. Integrated designs also struggle to meet the customized needs of customers for different application scenarios, increasing development cycles and complexity. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly.

[0023] Example 1 In the new energy industry, power supply product development and design cycles are typically long. However, increasingly fierce market competition has led to shorter development cycles. Current power supply designs often integrate on-board chargers with DC-DC converters, or even combine on-board chargers, DC-DC converters, and power distribution units into a single unit. This two-in-one or multi-in-one integration requires larger casings, increasing the likelihood of defects during the casting process. Furthermore, the long development cycles of these two-in-one or multi-in-one designs make them ill-suited to today's highly competitive market. Current integrated power supply designs lack flexibility and scalability, making it difficult to quickly adapt to different voltage platforms, such as the need to upgrade from 600V to 800V, resulting in system upgrade difficulties. Integrated designs increase production costs and maintenance complexity. Due to the lack of module independence and interchangeability, fault repair often requires complete replacement or complex maintenance, further increasing costs. Finally, current power supply product designs lack standardization and scalability, making it difficult to meet the customized needs of customers for different application scenarios, thus increasing development cycles and complexity. Current power supply development models are increasingly unable to meet market demands for high performance, high reliability, scalability, ease of maintenance, and low cost in the context of rapid technological iteration. Therefore, there is an urgent need to modularize power supplies to meet the requirements of rapid iteration.

[0024] In view of this, see Figure 1 , Figure 1The present invention provides structural schematic diagrams of three implementation methods for functional sub-modules. The functional sub-modules provided in this embodiment include a metal housing 100 and a functional board assembly 200. The metal housing 100 has a cavity structure with an opening at the top, and the side wall of the metal housing 100 has a connection port communicating with the interior of the cavity structure. The outer wall of the metal housing 100 has a connecting structure for connecting with the connecting structure of the metal housing 100 in an adjacent functional sub-module. The functional board assembly 200 is installed inside the metal housing 100, and the functional board assembly 200 has connecting feet extending out of the connection port for connecting with the connecting feet of the functional board assembly 200 in an adjacent functional sub-module.

[0025] Specifically, the functional submodule includes a metal housing 100, which provides a metal surface to reduce EMC (Electromagnetic Compatibility) impacts. The metal housing 100 is equipped with signal interfaces, etc.

[0026] This functional submodule includes a metal housing 100, which houses the functional board assembly 200 and provides support and fixation for it. The side wall of the metal housing 100 has connection ports, allowing the connection feet of the functional board assembly 200 to extend out and electrically connect with the connection feet of adjacent functional submodules for current transmission. The outer wall of the metal housing 100 has a connection structure, enabling adjacent functional submodules to be connected for structural connection. This functional submodule can be assembled flexibly and conveniently, has expandable functionality, improves development efficiency, reduces raw material costs, and caters to customers' multifunctional design needs. Furthermore, a power module assembled from multiple such functional submodules offers high assembly efficiency, ease of maintenance, and low repair costs.

[0027] The structure and shape of the functional submodules are described in detail below: In the optional solution provided by this utility model embodiment, the connection structure is set as a connection protrusion 110, the connection protrusions 110 are stacked in two adjacent functional sub-modules, and the fastener passes through one of the connection protrusions 110 and is threadedly connected to the other connection protrusion 110.

[0028] Specifically, the connecting protrusion 110 is provided with a mounting hole 113, and the fastener is threadedly connected to the mounting hole 113. In this embodiment, the fastener is a screw.

[0029] The connecting protrusions 110 of two adjacent functional sub-modules are stacked and connected by screws to achieve a detachable connection between the two. This makes disassembly and assembly simple, facilitates later maintenance, reduces maintenance costs, and provides high connection strength.

[0030] In the optional embodiment of this utility model, multiple outer walls of the metal shell 100 are provided with connecting structures.

[0031] Specifically, for example, if the metal shell 100 is rectangular and each of its two adjacent outer walls is provided with a connecting structure, then the two adjacent outer walls of the metal shell 100 can be connected to other metal shells 100, thereby achieving the connection of three metal shells 100 in an L-shaped arrangement.

[0032] Multiple outer walls of the metal housing 100 are provided with connection structures, enabling multiple outer walls of the metal housing 100 to be connected to other metal housings 100, thereby improving the scalability of the functional sub-modules.

[0033] For example: See Figure 1 The functional submodule includes a first module 310, which is rectangular in shape. Adjacent first and second sidewalls of the metal housing 100 of the first module 310 are provided with connecting protrusions 110. Each connecting protrusion 110 includes two cylindrical protrusions 111. (See also...) Figure 1 The functional submodule includes a second module 320, which is rectangular. The metal housing 100 of the second module 320 has connecting protrusions 110 on its adjacent first and second sidewalls. The connecting protrusions 110 on the first sidewall are plate-shaped protrusions 112, each with two mounting holes 113. The connecting protrusions 110 on the second sidewall include two cylindrical protrusions 111. The first module 310 and the second module 320 represent two implementations of the functional submodule.

[0034] See Figure 1 and Figure 3 The first sidewall of the first module 310 is adjacent to the first sidewall of the second module 320, and the protrusion 111 on the first sidewall of the first module 310 is located on the protrusion plate 112 on the first sidewall of the second module 320. The screw passes through the mounting hole 113 of the protrusion plate 112 and is threadedly connected to the protrusion 111.

[0035] Based on the above, see Figure 1 The functional submodule includes a third module 330, and a second module 320 that is rectangular and longer than the first module 310 and the second module 320. The first sidewall of the metal housing 100 of the third module 330 has a connecting protrusion 110, which includes two plate-shaped protrusions 112. The third module 330 described above is one embodiment of the functional submodule.

[0036] See Figure 1 and Figure 2The first sidewall of the third module 330 is adjacent to the second sidewall of the first module 310 and the second sidewall of the second module 320. A protrusion 111 on the second sidewall of the first module 310 is located on a protruding plate 112 on the first sidewall of the third module 330, and a protrusion 111 on the second sidewall of the second module 320 is located on another protruding plate 112 on the first sidewall of the third module 330. A screw passes through the protruding plate 112 and is threadedly connected to the protrusion 111; alternatively, a screw passes through the protrusion 111 and is threadedly connected to the protruding plate 112. In this embodiment, an M5 screw is used for fastening.

[0037] Based on the above, the metal housing 100 of the third module 330 has a connecting protrusion 110 on the third side wall opposite to the first side wall. The connecting protrusion 110 includes two plate-shaped protrusions 112 for connecting with other functional sub-modules.

[0038] Based on the above, the metal casing 100 of the third module 330 is provided with a water channel section. After the first module 310 and the second module 320 are both connected to the third module 330, heat dissipation can be carried out through the water channel section.

[0039] As another implementation, in the optional solution provided by this utility model embodiment, the connection structure is set as a snap-fit ​​protrusion or a snap-fit ​​groove, and the connection structure of the metal housing 100 in the adjacent functional sub-module is correspondingly set as a snap-fit ​​groove or a snap-fit ​​protrusion, and the snap-fit ​​protrusion can be inserted into the snap-fit ​​groove.

[0040] Specifically, the snap-fit ​​protrusion extends along the height direction of the metal housing 100, and correspondingly, the snap-fit ​​groove extends along the height direction of another metal housing 100. The two metal housings 100 can move along the height direction to allow the snap-fit ​​protrusion to be inserted into the snap-fit ​​groove. Alternatively, the snap-fit ​​protrusion extends along the length direction of the metal housing 100, and correspondingly, the snap-fit ​​groove extends along the length direction of another metal housing 100. The two metal housings 100 can move along the length direction to allow the snap-fit ​​protrusion to be inserted into the snap-fit ​​groove. Of course, schemes in which the snap-fit ​​protrusion and the snap-fit ​​groove extend in different directions to achieve connection between different sidewalls of the two metal housings 100 should also be within the protection scope of this utility model embodiment.

[0041] The metal housings 100 of two adjacent functional sub-modules are connected by mortise and tenon joints using snap-fit ​​protrusions and snap-fit ​​grooves, thereby achieving a detachable connection between the two.

[0042] In the optional embodiment of this utility model, the metal casing 100 is filled with potting compound.

[0043] Specifically, when the functional board assembly 200 within the functional submodule needs heat dissipation, the metal housing 100 is filled with potting compound.

[0044] Individual potting and vacuuming of functional sub-modules allows the adhesive to be better filled into the interior of the functional board assembly 200, thereby improving heat dissipation.

[0045] In the optional solution provided by this utility model embodiment, the connecting pins in two adjacent functional sub-modules are connected by wire harness screws.

[0046] When connecting two adjacent functional submodules for power, a wire harness screw fastening process is used to achieve a secure connection.

[0047] In the optional solutions provided by this utility model embodiment, the functional sub-modules are configured as an AC battery interference module, a high-voltage electromagnetic interference module, a large-capacity filter module, a magnetic water channel module, a low-voltage DC power supply module, or an electronic fuse module; the magnetic water channel module is filled with potting compound.

[0048] Specifically, the functional submodules can be configured as AC battery interference modules, high-voltage electromagnetic interference modules, high-capacity filter modules, magnetic water channel modules, low-voltage DC power supply modules, or electronic fuse modules. Of course, if the functional submodules are configured as other functional modules, they should also be within the protection scope of this utility model embodiment. The magnetic water channel module includes potting compound; separate potting and vacuuming of this module allows the compound to better fill the interior of the magnetic component, thereby improving the heat dissipation capacity of the magnetic component.

[0049] Example 2 The power module provided in this embodiment includes the functional sub-modules described in Embodiment 1, and therefore also possesses all the beneficial effects of Embodiment 1, which will not be repeated here.

[0050] In the optional solutions provided by this utility model embodiment, multiple functional sub-modules are provided, and the connection structures in two adjacent functional sub-modules are connected.

[0051] Specifically, the various functional sub-modules can be physically assembled into a power module through series and parallel connections according to customer interface location requirements. For multiple functional requirements, the individually assembled functional sub-modules can be physically connected.

[0052] By developing functional sub-modules independently, the development cycle can be greatly shortened; multiple functional sub-modules can be freely replaced, and functions can be added or deleted at will according to needs, making the development operation simple and convenient; each functional sub-module is independent of each other, and can be replaced individually during maintenance, greatly reducing maintenance costs.

[0053] In the optional solutions provided by the embodiments of this utility model, multiple functional sub-modules are arranged along the first direction a; or, multiple functional sub-modules are arranged along the second direction b; or, multiple functional sub-modules are arranged along the first direction a and the second direction b.

[0054] Specifically, multiple functional submodules are connected in series for power supply, and the metal casing 100 is structurally connected through series or parallel connections. It is worth noting that the volumes of different functional submodules vary; for example, see [link to example]. Figure 3 When multiple functional sub-modules are arranged along the first direction a and the second direction b, the first row has two small first modules 310 and second modules 320, and the second row has a large third module 330.

[0055] Multiple functional sub-modules can be arranged and assembled in different ways according to requirements, resulting in a highly flexible power supply module.

[0056] In the optional solution provided by this utility model embodiment, the power module includes a cover plate, which covers the opening end of the metal housing 100 of multiple functional sub-modules, and a sealing element is provided between the cover plate and the metal housing 100.

[0057] Specifically, each metal housing 100 is equipped with a sealing element. After the cover plate is placed on the metal housing 100, the housing forms a sealed cavity, thereby realizing the overall sealing function of the power module.

[0058] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
