Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage technology, and in particular to PCB board mounting device, PCB board integrated module and energy storage converter. Background Technology
[0002] Energy storage converters are commonly used electrical devices in the energy storage field, primarily used to convert between alternating current (AC) and direct current (DC). When charging a battery system, the energy storage converter converts AC to DC and stores it in the battery. When discharging to an external source, the energy storage converter converts DC to AC to supply the load.
[0003] An energy storage converter contains multiple PCB boards, such as IGBT power boards, driver boards, capacitor filter boards, power supply boards, and control boards. These PCB boards typically need to be electrically connected according to the power flow direction. For example, the driver board needs to be connected to the IGBT power board to drive the IGBT power board to work, the capacitor filter board needs to be connected to the IGBT power board to filter and optimize the converted power, and the power supply board and control board need to be connected to the IGBT power board to ensure power supply and control of the IGBT module.
[0004] Currently, the conventional method for electrical connection between PCB boards is through cable connection. This conventional method has several drawbacks: First, cable connection is complex and costly, with a long assembly cycle; second, cable routing is complex, as different PCB boards are placed in different locations, resulting in long cable routing paths and sometimes requiring dedicated routing paths, leading to complex wiring between PCB boards; third, PCB boards have poor maintainability, as replacing or repairing a PCB board requires disassembling many cables and even some components, resulting in poor maintainability.

[0037] Specifically, please refer to Figures 1 to 7This application provides a PCB board mounting device for mounting a PCB board 50. The PCB board mounting device may include a housing 10, a front panel assembly 20, and a rear panel assembly 30. The housing 10 extends through the front-rear direction. The front panel assembly 20 includes a front mounting plate 21 and a front panel 22. The front mounting plate 21 is detachably mounted on the front side of the housing 10. The front panel 22 is disposed inside the front mounting plate 21 and has multiple sets of female connectors 221 arranged at intervals in the horizontal or numerical direction. The female connectors 221 are used to insert into male connectors 52 of the PCB board 50. The rear panel assembly 30 is detachably mounted on the rear side of the housing 10 and has multiple sets of functional openings 311 corresponding to each set of female connectors 221. The functional openings 311 are used to expose the functional interfaces 53 of the PCB board 50. In other words, when installing the PCB board 50, the male plug 52 of the PCB board 50 can be plugged into the female plug 221 of the front panel 22 to realize the electrical connection between multiple PCB boards 50. Then, the rear panel assembly 30 is installed on the housing 10 so that the functional opening 311 of the rear panel exposes the functional interface 53 of the PCB board so that the cable can be connected to the functional interface 53 of the PCB board.
[0038] It is understood that the PCB board mounting device of this application utilizes the female connector 221 of the front panel 22 and the male connector 52 of the PCB board 50 to achieve electrical connection between different PCB boards 50, enabling the PCB boards 50 to be centrally mounted in the device. This reduces cable connections and wiring design, and significantly improves the maintainability of the PCB boards 50. When maintaining the PCB board 50, it is only necessary to remove the rear panel assembly 30, disconnect the male connector 52 of the PCB board 50 from the female connector 221 of the front panel 22, and slide it out of the housing 10 to perform maintenance.
[0039] Furthermore, such as Figure 4 and Figure 5As shown, in some embodiments, the PCB board mounting device further includes multiple PCB fasteners 40, which are respectively fixed to the inner wall of the housing 10. Each PCB fastener 40 has a sliding groove 41 extending in the front-rear direction for inserting the board body 51 of the PCB board 50. Each PCB fastener 40 corresponds to a set of female connectors 221. The PCB board 50 fasteners can be used to fix and mount the PCB board. When installing the PCB board 50, the board body 51 of the PCB board 50 can be slid into the housing 10 along the sliding groove 41, allowing the male connector 52 of the PCB board 50 to be inserted into the female connector 221 of the front panel 22. Similarly, when removing the PCB board 50, the PCB board 50 can be slid out of the housing 10 along the sliding groove 41, disengaging the male connector 52 of the PCB board 50 from the female connector 221 of the front panel 22. In this way, by using the slide groove 41 of the PCB fastener 40 to guide the PCB board 50 into and out of the housing 10, the positions of the male plug-in 52 and the female plug-in 221 can be quickly aligned, simplifying the disassembly and assembly of the PCB board 50.
[0040] Optionally, in some embodiments, the housing 10 has a cuboid structure, and multiple sets of female inserts 221 can be arranged at intervals along the vertical direction on the front panel 22. PCB fasteners 40 are disposed on the left and right sides of the housing 10. When installing the PCB board 50, the sliding grooves 41 of the PCB fasteners 40 can support the left and right sides of the PCB board 50 respectively, so that the PCB board 50 is placed horizontally, and multiple PCB boards 50 are stacked along the vertical direction.
[0041] Preferably, as shown in 4, in some embodiments, multiple sets of female plug-in 221 are arranged at intervals along the left and right direction on the front panel 22, and multiple fasteners are respectively disposed on the top, bottom or top and bottom of the housing 10.
[0042] When installing the PCB board 50, the PCB fastener 40 located at the top or bottom of the housing 10 can restrict one side of the PCB board 50. The PCB board 50 is placed vertically, and with the insertion force of the male plug 52 and the female plug 221, the PCB board 50 is fixed, so that multiple PCB boards 50 are stacked in the left and right direction.
[0043] Preferably, in some embodiments, the thickness of the PCB board 50 is less than the width of the slide groove 41 of the PCB board mounting device. This creates a certain gap between the PCB board 50 and the slide groove 41, making it easier for the PCB board 50 to be inserted into the slide groove 41.
[0044] Furthermore, such as Figure 3 and Figure 7As shown, in some embodiments, the rear panel assembly 30 includes multiple sub-mounting plates 31, which are detachably mounted on the housing 10. Each sub-mounting plate 31 corresponds to a set of female plug-in 221, and each sub-mounting plate 31 has a set of functional openings 311. Thus, each sub-mounting plate 31 corresponds to one PCB board 50. When maintaining one PCB board 50, the cable connected to that PCB board 50 can be removed, and the corresponding sub-mounting plate 31 can be individually disassembled to remove the PCB board 50 from the housing 10 without affecting other PCB boards 50, making the maintenance of the PCB boards 50 more convenient and faster.
[0045] It is worth noting that the shape of the functional opening 311 on each sub-mount plate 31 corresponds to the functional interface 53 on the rear side of the PCB board 50 corresponding to that sub-mount plate 31, so as to prevent dust and other impurities from entering the housing 10 through the gap between the sub-mount plate 31 and the functional interface 53.
[0046] like Figure 3 and Figure 4 As shown, in some embodiments, the rear panel assembly 30 further includes a plurality of fixing bolts 32, each sub-mounting plate 31 is provided with a pair of through holes 312, and the housing 10 is provided with a plurality of bolt holes. The fixing bolts 32 pass through the through holes 312 and are screwed into the bolt holes to fix the sub-mounting plate 31. In this way, the sub-mounting plate 31 can be fastened to the housing 10 by the fixing bolts 32. When maintaining the PCB board 50, the sub-mounting plate 31 can be removed from the housing 10 by unlocking the fixing bolts 32.
[0047] In particular, in some embodiments, the fixing bolt 32 can be a thumb screw. By utilizing the knurling on the thumb screw head, maintenance personnel can directly unlock the thumb screw without the aid of tools, making the disassembly and assembly of the PCB board 50 more convenient.
[0048] like Figure 2 and Figure 4 As shown, in some embodiments, the front panel assembly 20 further includes a display assembly 23. The front mounting plate 21 has a display window 211, and the display assembly 23 is disposed in the display window 211 of the front mounting plate 21 and connected to the front panel 22. The display assembly 23 can generally be a display screen, capable of displaying control information of the PCB board 50, such as open-loop mode, open-loop given voltage, feedback voltage, given current, feedback current, etc. By referring to the control information displayed by the display assembly 23, maintenance personnel can more intuitively detect and set the status of the PCB board 50.
[0049] like Figure 1 and Figure 2As shown, in some embodiments, the front panel assembly 20 further includes a pair of mounting ears 24, which are respectively disposed on the left and right sides of the housing 10. Each mounting ear 24 is provided with a plurality of mounting holes 241 arranged in the vertical direction. In this way, the housing 10 can be fixed to the energy storage converter through the fixing holes on the mounting ears 24, realizing the assembly of the device and the energy storage converter.
[0050] like Figure 2 As shown, preferably, in some embodiments, the mounting hole 241 is an oblong hole extending in the left-right direction, that is, the length of the oblong hole in the left-right direction is greater than its height in the up-down direction. In this way, by using the oblong hole to form an assembly allowance in the left-right direction, the position of the device can be adjusted within a certain range when assembling the device with the energy storage converter, making the installation of the device more convenient and accurate.
[0051] Furthermore, such as Figure 6 As shown, this application also provides a PCB board integration module, which may include a PCB board mounting device as described above and multiple PCB boards 50. Each PCB board 50 includes a board body 51, a male connector 52 disposed on the front side of the board body 51, and a functional interface 53 disposed on the rear side of the board body 51. Each board body 51 is slidably inserted into a slot 41 of the PCB board mounting device. The male connector 52 is inserted into a female connector 221 of the PCB board mounting device. The functional interface 53 is disposed in a functional opening 311 of the PCB board mounting device. In this way, by using the PCB board mounting device, multiple PCB boards 50 can be installed in one device, eliminating the trouble of cable connection and wiring design, and greatly improving the maintainability of the PCB boards 50.
[0052] This application also provides an energy storage converter, which may include: the aforementioned PCB board integration module and a main body of the device, wherein the PCB board integration module is installed in the main body of the device. Using the PCB board integration module, the PCB boards can be centralized in one location, simplifying the installation structure of the PCB boards within the energy storage converter and eliminating the need for complex wiring designs.
[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
