[0009] In some embodiments, optionally, the circuit board assembly includes a plurality of circuit boards, and adjacent two circuit boards are fixedly connected by a connecting column.

Screws are fixed in the first screw hole and the second screw hole to fixedly connect the circuit board and the guide rail.

[0011] In some embodiments, optionally, the lower guide rail plate is detachably connected to the housing by screws.

[0012] In some embodiments, optionally, the conductive layer is a copper layer.

[0013] In some embodiments, optionally, the housing has two side plates disposed opposite to each other. A set of fixing holes is provided in two corner regions on the same side of each side plate. The set of fixing holes includes three fixing holes, and the three fixing holes are arranged in an L shape in the corner region, so that any one side edge of the corner region has two of the fixing holes, and the distance between the two fixing holes on any one side edge of the corner region is the same;

[0014] The energy storage control device further includes an L-shaped plate. Two positioning holes are provided in the L-shaped plate. The two positioning holes correspond to the two fixing holes on any one side edge of the corner region.

Detailed Embodiments

[0023] To make the above objects, features, and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application is provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0024] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0026] In the present application, unless otherwise clearly defined and limited, the terms "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] In the present application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0028] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0029] In existing industrial and commercial energy storage or microgrid control devices, the circuit boards are usually fixed by means of press riveting studs, etc. The installation of the circuit boards is relatively complex, which is not convenient for the assembly of the devices, and the internal structure and wiring of the devices are complex, with poor integration. When there are multiple circuit boards, it is relatively difficult to install them one by one in the device, making it difficult to place the circuit boards and difficult to design the grounding scheme for the circuit boards.

[0030] Therefore, the present utility model provides an energy storage control device, which includes a housing 20 and a circuit board assembly disposed in the housing 20. Among them, the housing 20 is grounded, and a guide rail is provided on each of two opposite inner side walls in the housing 20, and the guide rail is in conductive contact with the housing 20; the circuit board assembly includes at least one circuit board 23, and the circuit board 23 is inserted and fixed in the guide rail, and the part of the circuit board 23 inserted in the guide rail is in conductive contact with the guide rail, so that the circuit board 23 is grounded in sequence through the guide rail and the housing 20.

[0031] In this embodiment, the guide rail includes an upper guide rail plate 21 and a lower guide rail plate 22. The upper guide rail plate 21 and the lower guide rail plate 22 are spaced apart to form a gap for inserting the circuit board 23. The lower guide rail plate 22 is fixedly connected to the housing 20, and the upper guide rail plate 21 is detachably connected to the lower guide rail plate 22. Specifically, the lower guide rail plate 22 can be fixedly connected to the side wall of the housing 20 through connectors such as screws. The upper guide rail plate 21 is arranged parallel and spaced apart from the lower guide rail plate 22, and the gap between the two can accommodate the circuit board 23 clamped therein. In some embodiments, optionally, the upper guide rail plate 21 is detachably connected to the lower guide rail plate 22 through screws. By setting the upper guide rail plate 21 and the lower guide rail plate 22 to be detachably connected, when installing the circuit board assembly, the lower guide rail plate 22 can be first fixedly connected to the inner wall of the housing 20, then the two ends of the circuit board 23 are placed on the upper surfaces of the lower guide rail plates 22 on both sides, and then the entire circuit board 23 is slowly pushed into the housing 20. After being pushed in place, the upper guide rail plate 21 is fixed to the lower guide rail plate 22 and the circuit board 23 through screws, and the circuit board 23 is clamped between the upper guide rail plate 21 and the lower guide rail plate 22 to limit the displacement of the circuit board 23 in the vertical and planar directions. Moreover, this detachable connection method enables the circuit board assembly to be installed outside the housing 20 first, and then the upper-layer PCB is placed on the lower guide rail plate 22 after installation, which facilitates the assembly of the circuit board assembly and avoids the cumbersome process of individually installing the circuit board 23 into the housing 20.

[0032] That is to say, in the energy storage control device of the present application, by providing a guide rail on two opposite inner side walls of the housing 20, the circuit board assembly is directly inserted and fixed in the guide rail, realizing the simple installation of the circuit board 23. The staff can first complete the assembly between multiple circuit boards 23 outside the housing 20 and then directly push them into the guide rail of the housing 20, reducing the installation difficulty. And since the housing 20 is grounded, the circuit board 23 is further grounded via the housing 20 by electrically contacting the guide rail, ensuring the stability of grounding. Thus, the guide rail simultaneously plays the roles of fixing and grounding, simplifies the wiring inside the device, and facilitates the arrangement of the circuit board 23.

[0033] In some embodiments of the present application, optionally, a conductive layer is laid on at least one surface of the part of the circuit board 23 inserted in the guide rail, and the conductive layer is in electrical contact with the guide rail. That is to say, in order to achieve a good grounding effect between the circuit board 23 inserted in the guide rail and the guide rail, a conductive layer can be laid on at least one surface of the part of the circuit board 23 inserted in the guide rail (i.e., both ends of the circuit board 23), and the conductive layer is used to achieve good electrical contact with the guide rail, thereby ensuring that the circuit board 23 is grounded over a large area and the grounding effect of the circuit board 23 is good. Optionally, the conductive layer can be a copper skin layer.

[0034] In some embodiments, optionally, the circuit board assembly includes a plurality of circuit boards 23. Adjacent circuit boards 23 are fixedly connected through connection posts 24. The grounding portions of the plurality of circuit boards 23 are electrically connected through the connection posts 24, and are grounded through the circuit board 23 inserted in the guide rail, the guide rail, and the housing 20.

[0035] That is to say, when the circuit board assembly includes a plurality of circuit boards 23, the plurality of circuit boards 23 can be stacked. Adjacent circuit boards 23 are fixedly connected through connection posts 24. For example, the connection post 24 can be a hexagonal prism or the like. At this time, as long as any one of the circuit boards 23 on both sides of the circuit board assembly is inserted and fixed in the guide rail, the fixation of all the circuit boards 23 in the housing 20 can be realized.

[0036] In this embodiment, the grounding portions of the plurality of circuit boards 23 are electrically connected through the connection posts 24, and then grounded through the circuit board 23 inserted in the guide rail, the guide rail, and the housing 20. Thus, the grounding of all the circuit boards 23 in the circuit board assembly is realized. The grounding method is simple and convenient, saving wiring.

[0037] In other embodiments of the present application, optionally, at least one first screw hole is provided on both sides of the circuit board 23 inserted in the guide rail. Second screw holes are provided at positions corresponding to the first screw holes on the guide rail. Screws are fixed in the first screw holes and the second screw holes to fixedly connect the circuit board 23 and the guide rail. In this embodiment, the guide rail and the circuit board 23 are fixed by screws, which is convenient for disassembly between the two. Among them, the number of the first screw holes can be multiple, and the number of the corresponding second screw holes is also multiple. When the circuit board 23 and the guide rail are fixed by screws passing through the first screw holes and the second screw holes, multi-point grounding of the circuit board 23 can also be realized to ensure effective contact between the circuit board 23 and the guide rail.

[0038] In some embodiments of the present application, optionally, the housing 20 has two side plates arranged opposite to each other. A set of fixing holes is provided in two corner regions on the same side of each side plate. The set of fixing holes includes three fixing holes, and the three fixing holes are arranged in an L shape in the corner region, so that any one side edge of the corner region has two fixing holes, and the distance between the two fixing holes on any one side edge of the corner region is the same; the energy storage control device further includes an L-shaped plate 25. Two positioning holes are provided on the L-shaped plate 25. The two positioning holes correspond to the two fixing holes on any one side edge of the corner region. The L-shaped plate 25 is fixedly connected to the side plate by screws passing through the fixing holes and the positioning holes.

[0039] In this embodiment, the housing 20 includes two side plates arranged oppositely. For each side plate, a set of fixing holes is provided at two corner regions on the same side of the side plate. Each set of fixing holes includes three fixing holes, and the three fixing holes in the same set are arranged in an L shape in the corner region, so that there are two fixing holes on any one side edge of the corner region. Optionally, the connecting line of the centers of the two fixing holes on each side edge is parallel to the side edge, and the distance between the centers of the two fixing holes on each side edge is the same.

[0040] The energy storage control device in this embodiment further includes an L-shaped plate 25. Two positioning holes are provided on the L-shaped plate 25, and the two positioning holes correspond to the two fixing holes on any one side edge of the corner region, that is, the distance between the centers of the two positioning holes is the same as the distance between the centers of the two fixing holes on each side edge. By rotating the L-shaped plate 25, the two positioning holes on the L-shaped plate 25 can be made to correspond to the two fixing holes on any one side edge. Then, the L-shaped plate 25 can be fixed to the housing 20 by screwing through the fixing holes and the positioning holes. After that, the L-shaped plate 25 is fixed to other objects such as a wall, and finally the energy storage control device is fixed.

[0041] Among them, the number of L-shaped plates 25 can be multiple, such as two, three, four, etc. By connecting the L-shaped plates 25 to different groups of fixing holes on the housing 20, or different two fixing holes in the same group, different fixing methods of the energy storage control device can be realized, so as to meet the installation selection in various scenarios.

[0042] In some embodiments of the present application, the L-shaped plate 25 includes a first plate body and a second plate body arranged vertically. The two fixing holes are provided on the first plate body, and a third fixing hole is provided on the second plate body. The third fixing hole is used for fixed connection with objects such as a wall by screws.

[0043] In some embodiments, optionally, the number of the L-shaped plates 25 is two, and one L-shaped plate 25 is fixed to each side plate, and the L-shaped plates 25 on the two side plates are symmetrically arranged. Thus, the energy storage control device can be hung on objects such as a wall by the two L-shaped plates 25. When the energy storage control device is fixed by the two L-shaped plates 25, by adjusting which set of fixing holes on the connecting side plate of the L-shaped plate 25, the adjustment of the orientation of different surfaces of the energy storage control device can be realized.

[0044] In other embodiments, optionally, the number of the L-shaped plates 25 is four, and two L-shaped plates 25 are fixed to each side plate, and the L-shaped plates 25 on the two side plates are symmetrically arranged, and the two L-shaped plates 25 on the same side plate are arranged on the same side edge of the side plate. By fixing the energy storage control device with four L-shaped plates 25, the fixing effect can be enhanced.

[0045] The following is an exemplary introduction to different connection methods of the L-shaped plates 25.

[0046] (a) When four L-shaped plates 25 are fixed, the corresponding fixing holes of the four L-shaped plates 25 are: fixing hole 4 and fixing hole 5, fixing hole 6 and fixing hole 7, fixing hole 11 and fixing hole 12, fixing hole 13 and fixing hole 14;

[0047] (b) When two L-shaped plates 25 are fixed, the corresponding fixing holes of the two L-shaped plates 25 are: fixing hole 1 and fixing hole 4, fixing hole 8 and fixing hole 11;

[0048] (c) When two L-shaped plates 25 are fixed, the corresponding fixing holes of the two L-shaped plates 25 are: fixing hole 3 and fixing hole 7, fixing hole 10 and fixing hole 14.

[0049] In some embodiments of the present application, optionally, the energy storage control device further includes a guide rail buckle 26, which is disposed on the outer surface of the top plate connected between the two side plates. The guide rail buckle 26 is used for clamping with an external guide rail to suspend and fix the energy storage control device. By adding a guide rail buckle 26, the energy storage control device can be fixed to the guide rail by using the guide rail buckle 26, further increasing the installation options of the energy storage control device for different scenarios.

[0050] In summary, for the energy storage control device in the present application, by providing a guide rail on two opposite inner side walls of the housing, the circuit board assembly is directly inserted and fixed in the guide rail, realizing the simple installation of the circuit board. Since the guide rail includes an upper guide rail plate and a lower guide rail plate that are detachably connected, and the lower guide rail plate is fixedly connected to the housing, the staff can first complete the assembly between multiple circuit boards outside the housing, and then directly push them onto the lower guide rail plate of the housing, and then fix the upper guide rail plate to the lower guide rail plate by screws or the like, clamping the circuit board between the upper guide rail plate and the lower guide rail plate. Thereby, the installation difficulty of the circuit board assembly is reduced, and the situation where the circuit board cannot be smoothly pushed into the guide rail gap due to the existence of assembly tolerances in the case of pre-fixing the guide rail is avoided; and since the housing is grounded, the circuit board is further grounded via the housing by electrically contacting the guide rail, ensuring the stability of grounding. Thus, the guide rail simultaneously plays the roles of fixing and grounding, simplifies the wiring inside the device, and facilitates the setting of the circuit board.

[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0052] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
