[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0028] According to an embodiment of the present invention, an energy storage combiner cabinet is provided, comprising: a cabinet 1, which encloses and forms a receiving space, and at least one side of the cabinet 1 forms an inlet / outlet 11 communicating with the receiving space; and a combiner module 2, which is movably disposed on the cabinet 1, the combiner module 2 being adapted to move into or out of the receiving space along a first direction from the inlet / outlet 11, the combiner module 2 including a support leg structure 21, the support leg structure 21 being adapted to support the combiner module 2 at a predetermined position when it moves out of the receiving space.

[0029] By using the energy storage combiner cabinet of this embodiment, after the combiner module 2 is assembled externally, it is fitted with the cabinet 1 and moved into the receiving space, thus integrating the combiner module 2 into the energy storage cabinet without the need for a separate combiner cabinet. Furthermore, when the combiner module 2 needs to be inspected, maintained, or updated, it can be pulled out from the cabinet 1 and supported by the support leg structure 21 for operation. Therefore, modular installation of the combiner module 2 is achieved, the overall structure is simple, the manufacturability and maintainability are better, and production and installation efficiency is improved.

[0030] It is worth noting that the first direction refers to the direction perpendicular to the surface where the inlet / outlet 11 is located. The cabinet 1 includes an inspection door, which is closable and can be installed at the inlet / outlet 11. That is, when it is necessary to remove the busbar module 2 from the cabinet 1, the inspection door can be opened, and then the busbar module 2 can be pulled out. After completing the inspection, maintenance, and update operations, the busbar module 2 can be pushed back into the cabinet 1 and the inspection door can be closed.

[0031] It should be further clarified that the side of cabinet 1 refers to the surface of cabinet 1 that extends along the height direction (i.e., the vertical direction), and not the top and bottom surfaces.

[0032] Furthermore, in one embodiment, the outrigger structure 21 is a telescopic outrigger. Specifically, it can be electrically telescopic, pneumatically telescopic, hydraulically telescopic, or manually telescopic.

[0033] Understandably, when the outrigger structure 21 is needed for support, the telescopic outrigger can be extended and positioned at a predetermined location. When no support is needed, the telescopic outrigger can be retracted to reduce space occupation.

[0034] As an alternative implementation, the leg structure 21 can also be a folding leg or a detachable leg.

[0035] In one embodiment, such as Figures 1 to 4 As shown, the busbar module 2 includes a support structure 22 and a load-bearing structure 23. The support structure 22 is disposed in the accommodating space and connected to the cabinet 1. The support structure 22 extends along a first direction. The load-bearing structure 23 is movably disposed on the support structure 22. On the two sides of the load-bearing structure 23 that are disposed opposite each other along a second direction, one side forms a load-bearing surface 231, and the support leg structure 21 is disposed on the other side.

[0036] It's worth noting that the second direction is the height direction, that is, the vertical direction. This is understandable, as... Figure 1 and Figure 2 As shown, the bearing surface 231 is the upper surface of the bearing structure 23, and the leg structure 21 is located on the lower surface of the bearing structure 23.

[0037] Furthermore, in one embodiment, such as Figures 1 to 3 As shown, the bus module 2 also includes an electrical component 26, which is disposed on the bearing surface 231. The bus module 2 also includes a busbar 27, which is electrically connected to the electrical component 26 and extends downward after passing through the bearing structure 23.

[0038] In one embodiment, the support structure 23 is a tray. The tray can be used to install components of energy storage systems with different capacity ratios.

[0039] It is understandable that the electrical components 26 and busbar 27 can be installed on the support structure 23 outside the cabinet 1, and then the support structure 23 together with the electrical components 26 and busbar 27 can be pushed into the cabinet 1 along the support structure 22.

[0040] In one embodiment, such as Figure 2 As shown, at least one support leg structure 21 is provided on the edge of the supporting structure 23 along the first direction near the inlet / outlet 11. When assembling the busbar module 2 or when it is necessary to inspect, maintain, or update the busbar module 2, the supporting structure 23 is pulled out from the cabinet 1. The side of the supporting structure 23 away from the inlet / outlet 11 is attached to the support structure 22, and the side of the supporting structure 23 near the inlet / outlet 11 is supported by the support leg structure 21. This realizes the pre-integration and assembly line installation of the busbar module 2, and facilitates the inspection, maintenance, and update of the busbar module 2.

[0041] It is worth noting that the leg structure 21 is provided at least in the area near the outer edge of the lower surface of the load-bearing structure 23.

[0042] Specifically, in one embodiment, such as Figure 1 and Figure 2 As shown, several support leg structures 21 are provided, and these support leg structures 21 are respectively arranged close to the opposite sides of the load-bearing structure 23 along the first direction. When the load-bearing structure 23 is completely outside the cabinet 1, the support leg structures 21 support the load-bearing structure 23, enabling the assembly of other components on the load-bearing structure 23 without the need for other auxiliary tooling.

[0043] That is, the support leg structure 21 is not only provided on the area near the outer edge of the lower surface of the support structure 23, but also on the area near the inner edge of the lower surface of the support structure 23. Therefore, when the support structure 23 is completely outside the cabinet 1, it can provide stable support for the support structure 23.

[0044] Furthermore, in one embodiment, such as Figure 1 and Figure 2 As shown, the support leg structure 21 is positioned at the four corners of the load-bearing structure 23.

[0045] In one embodiment, such as Figure 1 and Figure 3 As shown, a pair of support structures 22 are arranged at relative intervals along a third direction, and the load-bearing structures 23 are respectively arranged on the pair of support structures 22 on opposite sides along the third direction. Using a pair of support structures 22 to support the load-bearing structures 23 on opposite sides improves the support effect of the load-bearing structures 23 and ensures the stability of the load-bearing structures 23 during installation and movement.

[0046] It is worth noting that the third direction is a direction that is perpendicular to both the first and second directions. That is, the first direction, the second direction, and the third direction are all perpendicular to each other.

[0047] Specifically, in one embodiment, such as Figure 4 As shown, the support structure 22 includes a support plate 221 and a guide rail 222. The support plate 221 is connected to the cabinet 1, and the guide rail 222 is disposed on the support plate 221. The load-bearing structure 23 is disposed on the guide rail 222 and is movably disposed along the guide rail 222. The guide rail 222 guides the movement of the load-bearing structure 23, improving the smoothness of the movement and the accuracy of its position.

[0048] It is worth noting that, such as Figure 2 and Figure 3 As shown, the guide rail 222 extends along the first direction. The support plate 221 can extend along the first direction, or it can be arranged in several intervals along the first direction.

[0049] It should be noted that, in one embodiment, such as Figure 4 As shown, the guide rail 222 has an "L"-shaped cross-section perpendicular to the first direction, so that the bottom plate of the guide rail 222 supports the load-bearing structure 23, and the side plates of the guide rail 222 restrict the load-bearing structure 23. Of course, in other alternative embodiments, the cross-section of the guide rail 222 perpendicular to the first direction can be "U"-shaped, so that the guide rail 222 forms a guide groove, and the edge of the load-bearing structure 23 is inserted into the guide groove.

[0050] In one embodiment, such as Figure 4 As shown, a smooth pad 24 is provided on the surface of the guide rail 222 facing the support structure 23 and / or the surface of the support structure 23 facing the guide rail 222. The support structure 23 and the guide rail 222 are slidably connected through the smooth pad 24. By providing the smooth pad 24, the friction force during the movement of the support structure 23 is reduced, making it easier to move the support structure 23 in and out, and improving the convenience of operation.

[0051] Specifically, in one embodiment, the smooth pad 24 can be a PTFE pad. Of course, in other alternative embodiments, the smooth pad 24 can also be made of other materials with a low coefficient of friction. Alternatively, a material with a low coefficient of friction can be coated on the surface of the guide rail 222 that contacts the load-bearing structure 23.

[0052] It is worth noting that the smooth pad 24 can be provided only on the guide rail 222, or only on the load-bearing structure 23, or both the guide rail 222 and the load-bearing structure 23 can be provided with the smooth pad 24.

[0053] As an alternative implementation, in another embodiment, rolling elements are provided on the surface of the guide rail 222 facing the support structure 23 and / or the surface of the support structure 23 facing the guide rail 222, allowing the support structure 23 and the guide rail 222 to roll into contact via the rolling elements. By providing rolling elements, the frictional force during the movement of the support structure 23 is reduced, making it easier to move the support structure 23 in and out, and improving operational convenience.

[0054] It is worth noting that rolling elements can be provided only on the guide rail 222, only on the bearing structure 23, or on both the guide rail 222 and the bearing structure 23.

[0055] In one embodiment, such as Figures 1 to 4 As shown, the junction module 2 also includes a gripping part 25, which is connected to the support structure 23 and positioned close to the inlet / outlet 11. The gripping part 25 facilitates the movement of the support structure 23 in and out by workers / operating machinery (e.g., a robotic arm), improving operational convenience.

[0056] Specifically, the gripping part 25 can be set on the side of the bearing structure 23 facing the inlet and outlet 11, or it can be set on the edge of the bearing surface 231 near the inlet and outlet 11, so that it is convenient for staff to use through the inlet and outlet 11.

[0057] In one embodiment, such as Figure 2 and Figure 3 As shown, the energy storage combiner cabinet also includes a limiting and cooperating structure, which includes a plug-in component 3 and a socket. One of the plug-in component 3 and the socket is located on the side of the combiner module 2 away from the inlet / outlet 11 along the first direction, and the other is located on the side of the cabinet 1 opposite to the inlet / outlet 11 along the first direction. The plug-in component 3 is adapted to engage with the socket when the combiner module 2 is moved into the receiving space. By setting the limiting and cooperating structure, further guidance can be achieved when the combiner module 2 is moved into the cabinet 1, ensuring the accuracy of the installation position of the combiner module 2. At the same time, after the combiner module 2 is installed, it can be further limited to prevent the combiner module 2 from shaking during transportation.

[0058] Specifically, the connector 3 and / or the socket are located on the side of the bearing structure 23 away from the inlet / outlet 11.

[0059] It is understandable that when the connector 3 is located on the side of the support structure 23 away from the inlet / outlet 11, the socket is located on the side of the cabinet 1 opposite to the inlet / outlet 11 along the first direction; when the connector 3 is located on the side of the cabinet 1 opposite to the inlet / outlet 11 along the first direction, the socket is located on the side of the support structure 23 away from the inlet / outlet 11.

[0060] In one embodiment, the bus module 2 further includes a fixing structure, which is disposed on the support structure 22 and adapted to be fastened to the load-bearing structure 23. Specifically, the fixing structure can be bolts. After the load-bearing structure 23 is moved into place inside the cabinet 1, it can be fixed to the support structure 22 by bolts; when it is necessary to remove the load-bearing structure 23, the connection between the bolts and the load-bearing structure 23 can be removed, and the load-bearing structure 23 can be pulled out.

[0061] In one embodiment, such as Figure 6 As shown, the energy storage combiner cabinet also includes a power distribution module 4, which is located on one side of the combiner module 2 along the second direction. Specifically, the power distribution module 4 is positioned above the combiner module 2.

[0062] In one embodiment, the energy storage combiner cabinet further includes an energy storage unit disposed within the housing space. Specifically, such as... Figure 7 As shown, the cabinet 1 is equipped with a partition structure to divide the storage space into a battery compartment 12 and an electrical compartment 13. The energy storage unit is located in the battery compartment 12, the combiner module 2 is located in the electrical compartment 13, and the power distribution module 4 is also located in the electrical compartment 13.

[0063] It is worth noting that the inlet / outlet 11 is connected to the electrical compartment 13, but not to the battery compartment 12, in order to avoid the battery compartment 12 being connected to the outside world when the busbar module 2 is inspected, maintained or updated.

[0064] When the busbar module 2 of this embodiment needs to be inspected, maintained, or updated, the inspection door is opened to expose the inlet / outlet 11, and the bolts fixing the support structure 23 are removed. Then, the worker / robotic arm applies force to the support structure 23 through the gripping part 25 to pull the support structure 23, together with the electrical components 26 and the busbar 27, out of the cabinet 1. However, it does not need to be completely pulled out so that the support structure 22 supports the rear end of the support structure 23, and the support leg structure 21 located at the front end of the support structure 23 is lowered to support the front end of the support structure 23. Then, inspection, maintenance, or update operations can be performed.

[0065] After the operation is completed, the support leg structure 21 is retracted, and the worker / robotic arm applies force to the load-bearing structure 23 through the gripping part 25 to push the load-bearing structure 23, together with the electrical components 26 and the busbar 27, into the cabinet 1, and make the plug-in component 3 and the socket fit together; finally, the bolts are screwed into the load-bearing structure 23 to fix the load-bearing structure 23 to the support structure 22, and the maintenance door is closed.

[0066] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
