[0002] Existing electrical equipment, such as uninterruptible power supply devices, generally install electrical modules into a cabinet to protect the electrical modules. However, in general, the size of the cabinet is fixed. Although the number of electrical modules, such as battery modules, in the cabinet can be adjusted as needed, the size of the cabinet cannot be adjusted accordingly. This results in the cabinet always occupying a fixed space regardless of actual needs. Utility Model Content

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background technology and to provide a modular stacked electrical component, which can adjust the space occupied by the electrical component according to actual needs.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A modular stacked electrical component comprises: a plurality of electrical modules, each comprising a shell and an electrical unit located inside, wherein the electrical unit is used to realize a specific electrical function; a first mating portion and a second mating portion are provided at the bottom and top of the shell at corresponding positions; each of the electrical modules is configured to be suitable for being stacked on each other in a positioned manner through mutual cooperation between the first mating portion and the second mating portion.

[0006] Furthermore, the first matching portion of each electrical module is suitable for being inserted into the second matching portion of another electrical module along the stacking direction to achieve positioning.

[0007] Furthermore, in the housing, a support column is provided between the first matching portion and the second matching portion, and the support column is configured to be suitable for supporting the electrical module above it.

[0008] Furthermore, it also includes a plurality of fixing members, which are suitable for being installed on two stacked electrical modules through fasteners to achieve relative fixation between the two modules.

[0009] Furthermore, the electrical module includes a battery module and a control module; the battery module is used to store and release electrical energy, and the control module is connected to the battery module to control the battery module to supply power to the load.

[0010] Furthermore, there are multiple battery modules and one control module; each battery module is independently connected to the control module via a cable.

[0011] Furthermore, there are multiple battery modules and one control module; the control module is configured to determine the series-parallel connection relationship between the battery modules through the wiring relationship between the interfaces connected to the battery modules.

[0012] Furthermore, there are multiple battery modules and one control module; each battery module is connected to the control module in series via cables.

[0013] Furthermore, the number of the battery modules is multiple and the number of the control module is one; among the battery modules, at least some of the battery modules are connected in series through cables to form a cluster and then connected to the control module, and the control module is suitable for determining the series and parallel connection relationship between the battery modules of different clusters through the wiring relationship between the corresponding interfaces.

[0014] Furthermore, there are multiple battery modules and one control module; among the battery modules, at least some of the battery modules are connected in parallel via cables to form a cluster and then connected to the control module, and the control module is suitable for determining the series and parallel connection relationship between the battery modules of different clusters through the wiring relationship between the corresponding interfaces.

[0015] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0016] In the electrical component provided by the utility model, a first mating portion and a second mating portion corresponding in position are arranged on the shell of the electrical module, and the electrical modules are positioned relative to each other through the mating relationship between the first mating portion and the second mating portion, so that when the electrical modules are stacked, their respective positions can be ensured not to be offset, so that even if the stacking height of the electrical modules is high, they can still have good stability; the electrical components can be assembled by stacking each other, without the need for a cabinet, which can reduce the space occupied by the cabinet, and at the same time, the number of electrical modules can be adjusted according to actual needs, which is not restricted by the cabinet and has a higher degree of freedom.

[0017] Among them, the first mating part and the second mating part are positioned by plugging in, which can not only conveniently determine the position of the electrical module located on the top during stacking, but also avoid shaking and position displacement between the electrical modules due to external force after stacking, so that the electrical components after stacking are more stable.

[0018] In addition, a support column is arranged between the first mating part and the second mating part. Compared with the thinner sheet metal used in the shell, the support column has better supporting performance and can centrally support the weight of the electrical module. At the same time, through the support columns located at the same position, the weight of the electrical module can be directly transferred downward along multiple support columns to the ground, which has better supporting stability and can also prevent the electrical module below from being deformed due to excessive weight.

[0019] A fixing piece is provided, and the fixing piece can fix adjacent electrical modules into one body through fasteners, so as to avoid an unstable center of gravity caused by stacking the electrical modules too high.

[0020] The electrical module may be a battery module and a control module, wherein the control module may control the battery module to supply power to the load. There are generally multiple battery modules, and the control module may be connected to multiple battery modules at the same time.

[0021] For example, the battery modules can be independently connected to the control module through cables, or the battery modules can be connected in series in sequence and then connected to the control module. Generally speaking, the two are in a parallel and series relationship, but the actual series-parallel relationship can also be changed by adjusting the wiring relationship between the various interfaces of the control module; or, the battery modules can be connected in series to form a cluster before being connected to the control module, or the battery modules can be connected in parallel before being connected to the control module. At this time, the corresponding connection relationship can also be changed by adjusting the wiring relationship between the various interfaces of the control module. By adjusting the connection relationship between the battery module and the control module, the voltage and power output by the control module can be adjusted according to actual needs. The electrical component can not only adjust the actual output power by stacking, but also further adjust the output power according to the change of the wiring relationship after the stacking is completed.

[0034] Example

[0035] Reference Figure 1 Embodiment 1 of the utility model provides an electrical component, which includes a plurality of electrical modules 10. The electrical modules 10 can be stacked to form the electrical component and realize corresponding electrical functions, such as power supply, current conversion, voltage boost, voltage reduction, etc.

[0036] The electrical module 10 in the electrical component includes a housing 13 and an electrical unit located inside, wherein the electrical unit is used to realize a specific electrical function. For example, in this embodiment, the electrical module 10 includes a battery module 11 and a control module 12, wherein the battery module 11 is used to store and release electrical energy, and the control module 12 is connected to the battery module 11 to control the battery module 11 to supply power to the load, and at this time, the electrical component provides the function of supplying power to the load; the battery module 11 generally includes a battery unit and a DCDC converter, and the battery unit is connected to the DCDC converter, and the DCDC converter plays a role in adjusting the output voltage of the battery module 11; the control module 12 can be an uninterruptible power supply module, i.e., UPS. After the battery module 11 is connected to the UPS, the battery module 11 can be controlled by the UPS to supply power to the load, or the battery module 11 can be charged by connecting the UPS to an external power supply. The battery unit can be a lithium battery.

[0037] Reference Figure 2 and Figure 3 The bottom and top of the housing 13 of the electrical module 10 are provided with a first mating portion 131 and a second mating portion 132 corresponding to each other. Each electrical module 10 is configured to be stacked on each other in a positioned manner through the mutual cooperation of the first mating portion 131 and the second mating portion 132. Specifically, the housing 13 of the electrical module 10 is roughly a cuboid, and the size of the housing 13 of each electrical module 10 is the same. According to common understanding, the housing 13 includes a length, a width and a thickness. Figure 1 The length direction of the housing 13 corresponds to the front-to-back direction, the width direction corresponds to the left-to-right direction, and the thickness direction corresponds to the up-down direction. In this embodiment, the electrical modules 10 are stacked in the up-down direction, the first mating portions 131 are arranged at the four corners of the bottom of the housing 13 of the electrical module 10, and the second mating portions 132 are correspondingly arranged at the four corners of the top of the housing 13 of the electrical module 10.

[0038] Reference Figure 2 and Figure 3, the first mating portion 131 of each electrical module 10 is suitable for being inserted into the second mating portion 132 of another electrical module 10 along the stacking direction to achieve positioning. Among them, the first mating portion 131 is a raised structure, and the second mating portion 132 is a recessed structure. The first mating portion 131 can be inserted into the second mating portion 132, so as to achieve relative positioning between the electrical modules 10. At the same time, the first mating portion 131 is a raised structure, and the electrical module 10 located at the bottom of the stacked electrical components can also be supported by the first mating portion 131 as a support leg. Specifically, the main body of the shell 13 of the electrical module 10 is a sheet metal plate, and each sheet metal plate is combined and formed by welding or bolting. The first mating portion 131 can be formed by welding another metal component to the bottom of the shell 13, and the second mating portion 132 can be directly stamped on the sheet metal plate serving as the shell 13.

[0039] Reference Figure 4 In the housing 13, a support column 14 is provided between the first mating portion 131 and the second mating portion 132, and the support column 14 is configured to support the electrical module 10 above it. Specifically, the support column 14 extends in the up-down direction, and its top abuts against the bottom of the second mating portion 132, and its bottom abuts against the upper side wall of the bottom sheet metal of the housing 13, and corresponds to the position of the first mating portion 131. Therefore, when the electrical modules 10 are stacked to form an electrical assembly, when the first mating portion 131 of the electrical module 10 located at the top is inserted into the second mating portion 132 of the electrical module 10 located at the bottom, it is equivalent to sitting on the support column 14, and the support column 14 can transfer the weight of the electrical module 10 step by step to the support column 14 of the lowest electrical module 10, and then transfer it to the ground through the first mating portion 131 of the lowest electrical module 10, thereby enhancing the load-bearing capacity of the electrical module 10.

[0040] Reference Figure 4 In this embodiment, the housing 13 includes two left and right side panels 134. The top and bottom of the two side panels 134 extend inward to form a flange 135 with a certain width. The first matching portion 131 and the second matching portion 132 are respectively arranged on the flange 135 at the bottom and top of the side panels. At the same time, the flange 135 has a certain thickness, which can improve the load-bearing performance of the housing 13.

[0041] In addition, refer to Figure 1 The electrical assembly also includes a plurality of fixing members 20, which are suitable for being installed on the two stacked electrical modules 10 through fasteners 21 to achieve relative fixation between the two. Grooves 133 are also provided on the left and right sides of the electrical module 10 to Figure 1Taking the right position as shown, the housing 13 of the electrical module 10 is arranged with two grooves 133 in the middle position of the front-back direction of the right shell wall along the up-down direction. The two grooves 133 are respectively close to the upper surface and the lower surface of the housing 13, and screw holes are provided on the two grooves 133. The fixing member 20 is an arched metal sheet, and through holes are provided at both ends of the fixing member 20. The size of the fixing member 20 is just enough to allow both ends to extend into the two adjacent grooves 133 on the two adjacent electrical modules 10. Then, the fixing member 20 is locked on the housing 13 of the two electrical modules 10 by the fastener 21, so that the two electrical modules 10 can be fixed together, thereby avoiding the shaking and position displacement of the electrical modules 10 due to the excessive stacking height. In addition, in other embodiments, each electrical module 10 can also be fixed by an integral fixing member. For example, after the stacking is completed, the integral fixing member can be screwed with each electrical module 10, so as to achieve the purpose of fixing each electrical module 10.

[0042] In the electrical component provided in this embodiment, the number of battery modules 11 is multiple, and the number of control modules 12 is one. In other embodiments, the number of battery modules 11 and control modules 12 can be adjusted according to actual needs. For example, when it is necessary to power multiple loads, multiple control modules 12 are set in one electrical component, and each control module 12 is connected to a specific number of battery modules 11; or when the power required by the load is low, only one battery module 11 and one control module 12 can be set. Such increase, decrease, and adjustment in quantity are all modifications that can be made according to actual needs, and they do not depart from the scope of the present utility model. In addition, in other embodiments, the electrical component can also be laid down for use. When it is laid down, due to the action of the fixing parts, it can still form an integral electrical component.

[0043] In this embodiment, a connection port of the battery module 11 is provided on the rear side of the battery module 11, and a corresponding connection port is also provided on the rear side of the control module 12. The connection port of the battery module 11 can be connected to the connection port of the control module 12 through a cable, thereby realizing the connection between the battery module 11 and the control module 12. However, in actual applications, there are many ways to connect the battery module 11 and the control module 12, and various situations are described below.

[0044] As an implementation mode, each battery module 11 can be independently connected to the control module 12 via a cable. In this case, one battery module 11 can be provided with one interface or two interfaces. In the case of one interface, the interface includes positive and negative electrodes. In the case of two interfaces, the positive and negative electrodes can be respectively provided in the two interfaces. Correspondingly, the control module 12 is provided with multiple interfaces, which can provide positive and negative electrodes in one interface, or two interfaces form a combination of positive and negative electrodes. When the cable connects the battery module 11 and the control module 12, the connection is performed in a manner in which each battery module 11 is connected in parallel with each other. It should be noted that at this time, in addition to the matching relationship between the positive and negative electrodes, the interfaces on the control module 12 are all in parallel with each other. At this time, each battery module 11 is connected to the control module 12 in a parallel manner.

[0045] As another embodiment, a battery module 11 is provided with two interfaces, both of which are provided with positive and negative electrodes, which can respectively form the first end and the second end of the battery module 11. When wiring, starting from the bottom battery module 11, its second end is connected to the first end of the second battery module 11 above it, and the second end of the second battery module 11 is then connected to the first end of the third battery module 11 above it, and so on, until the top battery module 11, and its second end is connected to the interface of the control module 12. In this wiring method, each battery module 11 can be connected by a cable of the same length, which can facilitate the preparation of cables.

[0046] As another embodiment, the control module 12 is configured to determine the series-parallel connection relationship between the battery modules 11 through the wiring relationship between the interfaces connected to the battery modules 11. Specifically, the multiple interfaces of the control module 12 can be in a series or parallel relationship. For example, when the number of interfaces of the control module 12 is eight, four of the interfaces can be in a series relationship, and the other four interfaces can be in a parallel relationship. At this time, the battery modules 11 connected to the control module 12, even if they are independently connected through cables, will determine whether they are connected in series or in parallel based on the wiring relationship between the interfaces of the control module 12.

[0047] As another embodiment, each battery module 11 is connected to the control module 12 in series through cables. In this case, one battery module 11 can be provided with two interfaces, namely, a positive electrode interface and a negative electrode interface. The negative electrode of the battery module 11 at the bottom is connected to the interface on the control module 12, and the positive electrode of the battery module 11 is connected to the negative electrode of the battery module 11 above and adjacent to it, and so on, until it is connected to the positive electrode of the top battery module 11, and then the positive electrode is connected to the corresponding interface on the control module 12, thereby completing the series connection of the battery modules 11.

[0048] As another embodiment, in each battery module 11, at least some of the battery modules 11 are connected in series through cables to form a cluster and then connected to the control module 12. The control module 12 is suitable for determining the series-parallel connection relationship between the battery modules 11 of different clusters through the wiring relationship between the corresponding interfaces. Specifically, taking the number of battery modules 11 as eight as an example, the eight battery modules 11 are divided into four clusters, each cluster has two battery modules 11, and the two battery modules 11 are connected in series with each other. Each cluster leads out a positive cable and a negative cable to the interface of the control module 12. At the same time, the control module 12 also determines the series-parallel connection relationship between the battery modules 11 of different clusters according to the wiring relationship between its own interfaces. For example, the battery modules 11 of the four clusters can be set to have two clusters connected in series to the control module 12, and two clusters connected in parallel to the control module 12.

[0049] As another embodiment, among the battery modules 11, at least some of the battery modules 11 are connected in parallel through cables to form a cluster and then connected to the control module 12. The control module 12 is suitable for determining the series-parallel connection relationship between the battery modules 11 of different clusters through the wiring relationship between the corresponding interfaces. Specifically, taking the number of battery modules 11 as eight as an example, the eight battery modules 11 are divided into four clusters, each cluster has two battery modules 11, and the two battery modules 11 are connected in parallel to each other. Each cluster leads out a positive cable and a negative cable to the interface of the control module 12. At the same time, the control module 12 also determines the series-parallel connection relationship between the battery modules 11 of different clusters according to the wiring relationship between its own interfaces. For example, the battery modules 11 of the four clusters can be set to have two clusters connected in series to the control module 12, and two clusters connected in parallel to the control module 12.

[0050] In the electrical component provided by the utility model, a first mating portion 131 and a second mating portion 132 corresponding in position are arranged on the shell 13 of the electrical module 10, and the electrical modules 10 are positioned by the mating relationship between the first mating portion 131 and the second mating portion 132, so that when the electrical modules 10 are stacked, their respective positions can be ensured not to be offset, so that even if the stacking height of the electrical modules 10 is high, it can still have good stability; the electrical component can be assembled by stacking each other, without the need for a cabinet, which can reduce the space occupied by the cabinet, and at the same time, the number of electrical modules 10 can be adjusted according to actual needs, which is not restricted by the cabinet and has a higher degree of freedom.

[0051] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
