Description

Technical Field

[0001] This utility model relates to the field of energy storage controller technology, and in particular to a controller housing and controller outer shell. Background Technology

[0002] The Battery Storage Controller (BSC) is a key device in managing energy storage systems. It primarily monitors and controls the battery charging and discharging process to ensure the safe and efficient operation of the energy storage system. The BSC controller's housing mainly consists of an upper and lower shell formed using sheet metal processes. The shell is typically formed by bending sheet metal parts. To ensure strength, the flanges or edges created by bending usually require welding, riveting, or screwing to secure the structural connection and maintain structural strength. However, welding can easily lead to deformation of the flanges or edges, while riveting or screwing requires more parts, increasing costs, complicating installation, and consuming more time during assembly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology in which the fixing method between the shell flanges is easy to cause flange deformation or troublesome fixing and installation and high cost, and to provide a controller shell and controller housing.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A controller housing includes a cover plate, two first side plates, two second side plates, and a connecting plate;

[0006] The cover plate is bent at both ends in a first direction to form the first side plate, and the cover plate is bent at both ends in a second direction to form the second side plate; the cover plate, the two first side plates, and the two second side plates form a receiving cavity; wherein, the wall thickness direction of the cover plate is perpendicular to the plane formed by the first direction and the second direction;

[0007] The connecting plate is connected to the second side plate, and at least a portion of the connecting plate is located on one side of the first side plate in its wall thickness direction; one of the connecting plate and the first side plate is provided with a boss, and the other of the connecting plate and the first side plate is provided with a mounting hole; the connecting plate and the first side plate with the boss are defined as the first mounting plate, and the connecting plate and the first side plate with the mounting hole are defined as the second mounting plate; the mounting hole penetrates the second mounting plate in the wall thickness direction of the first side plate, and the boss extends into the mounting hole;

[0008] In the wall thickness direction of the first side plate, the port area of ​​the mounting hole at the end closer to the first mounting plate is smaller than the port area of ​​the mounting hole at the end farther away from the first mounting plate, and the boss is riveted and fixed to the mounting hole.

[0009] In this design, the connection between the first side plate and the connecting plate is achieved through riveting between the boss and the mounting hole, thereby fixing the first and second side plates to ensure the structural strength of the flanged area of ​​the controller housing. The boss and mounting hole can be directly machined into the first side plate and the connecting plate, reducing the number of parts required for fixing (such as screws or rivets), lowering material costs and inventory management complexity, simplifying the assembly process, making installation more convenient, and shortening installation time. Furthermore, the riveting method avoids the deformation risk associated with welding.

[0010] Preferably, the mounting hole includes a first mounting hole section and a second mounting hole section in the wall thickness direction of the first side plate, and the second mounting hole section is connected to the end of the first mounting hole section away from the first mounting plate in the wall thickness direction of the first side plate.

[0011] The inner diameter of the second mounting hole gradually increases from one end of the second mounting hole section facing the first mounting hole section along the wall thickness direction of the first side plate to the end of the second mounting hole section away from the first mounting hole section.

[0012] In this design, the gradually increasing hole length during the riveting process facilitates material flow, resulting in a more uniform riveted joint and improved connection reliability.

[0013] Preferably, the wall thickness of the second mounting plate is defined as t;

[0014] Before the boss is riveted to the mounting hole, the controller housing satisfies one or more of the following conditions:

[0015] a1. The outer diameter of the boss is 2*t~5*t;

[0016] b1. The height of the boss in the wall thickness direction of the first side plate is t~1.2*t.

[0017] In this solution, by limiting the size of the boss, it is ensured that the boss has sufficient deformation capacity, so that the boss can be stably connected to the second mounting plate with mounting holes after riveting deformation.

[0018] Preferably, before the boss is riveted to the mounting hole, the minimum diameter of the mounting hole is greater than the outer diameter of the boss.

[0019] In this solution, the above-mentioned settings reduce the difficulty of fitting the mounting holes and bosses, lower the manufacturing precision requirements of the mounting holes and bosses, and improve the assembly error tolerance.

[0020] Preferably, the cross-section of the mounting hole along the center line perpendicular to the mounting hole is an oblong shape, and the oblong shape includes a first arc segment, a straight segment and a second arc segment in sequence in the wall thickness direction of the cover plate, and the straight segment is parallel to the wall thickness direction of the cover plate.

[0021] In this design, the elongated oval mounting hole effectively absorbs the tolerance in the bending height direction of the controller housing, compensates for dimensional errors in sheet metal processing, and ensures accurate alignment between the boss and the mounting hole.

[0022] Preferably, the controller housing satisfies one or more of the following conditions:

[0023] a2. The length of the straight segment in the wall thickness direction of the cover plate is 0.2~0.5mm;

[0024] b2. Before the boss is riveted to the mounting hole, the distance between the outer peripheral wall of the boss and the inner wall of the mounting hole corresponding to the straight line segment is 0.05~0.1mm.

[0025] In this solution, the above-mentioned settings are used to ensure a stable connection between the boss and the mounting hole.

[0026] Preferably, the second mounting plate is located on the side of the first mounting plate away from the receiving cavity in the wall thickness direction of the first side plate.

[0027] In this solution, the above-mentioned setup allows operators to perform riveting operations on the outside of the controller housing, reducing the difficulty of riveting processing.

[0028] Preferably, the end of the second side plate in the first direction is bent toward the direction of the first side plate to form the connecting plate, the connecting plate being located on the side of the first side plate toward the receiving cavity in the wall thickness direction of the first side plate.

[0029] In this design, the connecting plate is formed by bending the second side plate, which improves the flange strength of the controller housing. The connecting plate is located on the side of the first side plate facing the receiving cavity, reducing external protrusions of the controller housing, making it both aesthetically pleasing and safe.

[0030] A controller housing, the controller housing comprising the controller housing as described above.

[0031] Preferably, there are two controller housings, with the open ends of the receiving cavities of the two controller housings facing each other, and the two controller housings are detachably connected to form a receiving space for accommodating the main control board.

[0032] In this solution, both the upper and lower housings of the controller housing can be made using the controller housing described above, thereby enhancing the overall strength of the controller housing.

[0033] The positive and progressive effects of this utility model are as follows: This utility model achieves the connection between the first side plate and the connecting plate through riveting and fixing between the boss and the mounting hole, thereby fixing the first side plate and the second side plate to ensure the structural strength of the flange of the controller housing. The boss and mounting hole can be directly machined into the first side plate and the connecting plate, reducing the number of parts required for fixing (such as screws or rivets), lowering material costs and inventory management complexity, simplifying the assembly process, making installation more convenient, and shortening installation time. At the same time, the riveting fixing method also avoids the deformation risk caused by welding. Attached Figure Description

[0056] Riveting auxiliary tooling 8 Detailed Implementation

[0057] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0058] This embodiment discloses a BSC controller for monitoring and regulating the battery charging and discharging process to ensure the safe and efficient operation of the energy storage system. The BSC controller includes a controller housing and a main control board. The controller housing has an internal accommodating space, and the main control board is disposed within this space and fixed to the controller housing.

[0059] The controller housing is generally assembled from two separate controller housings, namely an upper housing and a lower housing. The main control board is mounted on the lower housing, and the upper housing is located above the main control board. In this embodiment, both the upper and lower housings are box-shaped structures with flanges, meaning that both the upper and lower housings have an open-end receiving cavity inside. The open ends of the receiving cavities of the upper housing and the lower housing face each other. The upper and lower housings are detachably connected to form a receiving space for accommodating the main control board.

[0060] The following discloses a controller housing, which can be used as the upper housing of a controller shell, or as the lower housing of a controller shell, or both the upper and lower housings of a controller shell can use the controller housing.

[0061] like Figure 1 and Figure 2 As shown, the controller housing includes a cover plate 1, two first side plates 2, two second side plates 3, and a connecting plate 4.

[0062] like Figure 1 and Figure 9As shown, the cover plate 1 is bent at both ends in a first direction to form a first side plate 2, and the cover plate 1 is bent at both ends in a second direction to form a second side plate 3. The first side plate 2 and the second side plate 3 are flanged structures of the controller housing. The cover plate 1, the two first side plates 2, and the two second side plates 3 form a receiving cavity 7 for forming a receiving space. The receiving cavity 7 is located in the wall thickness direction of the cover plate 1 ( Figure 1 and Figure 7 The end furthest from cover plate 1 in the Z direction is the open end.

[0063] It should be noted that the wall thickness direction of the cover plate 1 is perpendicular to the plane formed by the first direction and the second direction. Specifically, in this embodiment, the first direction is the length direction of the cover plate 1. Figure 1 , Figure 4 , Figure 6 and Figure 8 The X direction is the first direction, and the second direction is the width direction of cover plate 1. Figure 1 (Y direction in the diagram). In other alternative embodiments, the first direction may also be the width direction of the cover plate 1, and the second direction may be the length direction of the cover plate 1.

[0064] Furthermore, such as Figure 2 As shown, the first side plate 2 is connected to the adjacent second side plate 3 via a connecting plate 4. Specifically, in this embodiment, the connecting plate 4 and the second side plate 3 are an integral structure. The end of the second side plate 3 in the length direction of the cover plate 1 is bent toward the first side plate 2 to form the connecting plate 4. The connecting plate 4 is formed by bending the second side plate 3, which improves the flange strength of the controller housing.

[0065] Furthermore, the connecting plate 4 is located on the side of the first side plate 2 facing the receiving cavity 7 in the wall thickness direction of the first side plate 2 (i.e., the length direction of the cover plate 1 in this embodiment), which reduces the external protrusion of the controller housing, making it aesthetically pleasing and safe.

[0066] In other alternative embodiments, the connecting plate 4 may be located on the side of the first side plate 2 away from the receiving cavity 7 in the wall thickness direction of the first side plate 2.

[0067] like Figures 2-8 As shown, one of the connecting plate 4 and the first side plate 2 is provided with a boss 5, and the other of the connecting plate 4 and the first side plate 2 is provided with a mounting hole 6. The connecting plate 4 and the first side plate 2 with the boss 5 is defined as the first mounting plate, and the connecting plate 4 and the first side plate 2 with the mounting hole 6 is defined as the second mounting plate. The mounting hole 6 passes through both ends in the wall thickness direction of the second mounting plate, and the boss 5 extends into the mounting hole 6.

[0068] In this embodiment, the connecting plate 4 is the first mounting plate, and the first side plate 2 is the second mounting plate, that is, the second mounting plate is located on the side of the first mounting plate away from the receiving cavity 7 in the wall thickness direction of the first side plate 2. The boss 5 is provided on the connecting plate 4, and the mounting hole 6 is provided on the first side plate 2. The mounting hole 6 penetrates the first side plate 2 at both ends in the wall thickness direction of the first side plate 2. The boss 5 extends into the mounting hole 6 from the inside to the outside. The operator can perform riveting operations on the outside of the controller housing, reducing the difficulty of riveting processing.

[0069] In other alternative embodiments, the first side plate 2 may be a first mounting plate, the boss 5 may be provided on the first side plate 2, the connecting plate 4 may be a second mounting plate, the mounting hole 6 may be provided on the connecting plate 4, and the mounting hole 6 may be through both ends in the wall thickness direction of the connecting plate 4.

[0070] In other alternative embodiments, the second mounting plate may be located on the side of the first mounting plate facing the receiving cavity 7 in the wall thickness direction of the first side plate 2, and the operator may perform the riveting operation from inside the receiving cavity 7 of the controller housing.

[0071] like Figure 6 and Figure 8 As shown, in the wall thickness direction of the first side plate 2, the port area of ​​the mounting hole 6 at the end closest to the first mounting plate is smaller than the port area of ​​the mounting hole 6 at the end furthest from the first mounting plate. The boss 5 is riveted to the mounting hole 6 to achieve the connection between the first side plate 2 and the connecting plate 4, thereby achieving the fixation between the first side plate 2 and the second side plate 3, to ensure the structural strength of the flange of the controller housing. The riveting method also avoids the deformation risk caused by welding.

[0072] Specifically, such as Figure 6 As shown, in this embodiment, the mounting hole 6 includes a first mounting hole segment 61 and a second mounting hole segment 62 in the wall thickness direction of the first side plate 2. The second mounting hole segment 62 is connected to the end of the first mounting hole segment 61 away from the first mounting plate in the wall thickness direction of the first side plate 2. Along the wall thickness direction of the first side plate 2 from the end of the second mounting hole segment 62 facing the first mounting hole segment 61 to the end of the second mounting hole segment 62 away from the first mounting hole segment 61, the inner diameter of the second mounting hole segment 62 gradually increases, i.e., the second mounting hole segment 62 is a funnel-shaped hole. The inner diameter of the first mounting hole segment 61 remains unchanged, and the inner diameter of the first mounting hole segment 61 is equal to the minimum diameter of the second mounting hole segment 62.

[0073] like Figure 8 As shown, before the boss 5 is riveted to the mounting hole 6, that is, before the boss 5 is deformed, the outer diameter of the boss 5 is smaller than the minimum hole diameter of the mounting hole 6, that is, the outer diameter of the boss 5 is smaller than the inner diameter of the first mounting hole section 61, so as to reduce the difficulty of fitting the mounting hole 6 and the boss 5, reduce the manufacturing precision requirements of the mounting hole 6 and the boss 5, and improve the assembly error tolerance.

[0074] In this embodiment, before the boss 5 is riveted to the mounting hole 6, the minimum distance between the outer peripheral wall of the boss 5 and the inner wall of the mounting hole 6 is 0.05~0.1mm. In other alternative embodiments, the distance between the outer peripheral wall of the boss 5 and the inner wall of the mounting hole 6 before the boss 5 is riveted to the mounting hole 6 can be designed to be other values, depending on the actual requirements.

[0075] like Figure 8 As shown, the boss 5 passes through the first mounting hole section 61 and extends into the second mounting hole section 62. The riveting tool applies pressure to the end of the boss 5 away from the first mounting plate, causing the end of the boss 5 away from the first mounting plate to deform and make an interference fit with the inner wall surface of the second mounting hole section 62. The outer diameter of the portion of the boss 5 located in the second mounting hole section 62 is larger than the diameter of the hole in the first mounting hole section 61, thereby fixing the boss 5 to the mounting hole 6. During the riveting process, the gradually enlarging second mounting hole section 62 facilitates material flow, forming a more uniform riveted joint and improving the reliability of the connection.

[0076] In this embodiment, the riveting tool extends into the second mounting hole section 62 to press the boss 5, ensuring that the boss 5 can tightly fit with the inner wall surface of the second mounting hole section 62. In other alternative embodiments, before the boss 5 is riveted to the mounting hole 6, the boss 5 can extend further beyond the second mounting hole section 62, and the riveting tool performs the riveting work outside the controller housing, that is, the riveting tool does not extend into the second mounting hole section 62, ensuring the connection strength between the boss 5 and the mounting hole 6.

[0077] Furthermore, in this embodiment, the single first side plate 2 and the single connecting plate 4 are connected by multiple bosses 5 and mounting holes 6 to ensure connection strength. During the processing, the riveting tool can either press only a single boss 5 in a single operation, or simultaneously press multiple bosses 5 located on the same side of the controller housing.

[0078] In other alternative embodiments, the mounting hole 6 can also be designed as a hole structure with a gradually changing inner diameter, that is, the mounting hole 6 is designed entirely with reference to the second mounting hole segment 62, and no longer has the first mounting hole segment 61 with a constant inner diameter.

[0079] In this embodiment, the boss 5 and the mounting hole 6 are directly machined on the first side plate 2 and the connecting plate 4. For example, the boss 5 can be formed by stamping the connecting plate 4, and the mounting hole 6 can be formed by punching the first side plate 2. This direct machining method reduces the number of parts required for fixing (such as screws or rivets), lowers material costs and inventory management complexity, simplifies the assembly process, makes installation more convenient, and shortens installation time.

[0080] Furthermore, such as Figure 9 As shown, to prevent deformation of the first side plate 2 and the connecting plate 4 during the riveting process, a riveting auxiliary fixture 8 can be provided in the receiving cavity 7 to support the first side plate 2 and the connecting plate 4. Specifically, the riveting auxiliary fixture 8 abuts against one end face of the connecting plate 4 facing the receiving cavity 7 in the wall thickness direction of the first side plate 2. The position of the riveting auxiliary fixture 8 is fixed to provide a stable and reliable supporting force to the first side plate 2 and the connecting plate 4.

[0081] Since the first side plate 2 and the second side plate 3 in this embodiment are formed by bending from the end of the cover plate 1, the bending error caused by the bending process will result in a certain tolerance in the height of the first side plate 2 and the second side plate 3 in the wall thickness direction of the cover plate 1. As a result, the position of the connecting plate 4 connected to the second side plate 3 relative to the first side plate 2 in the wall thickness direction of the cover plate 1 will also have a certain tolerance. This will result in a certain tolerance in the position of the mounting hole 6 on the first side plate 2 and the boss 5 on the connecting plate 4 in the wall thickness direction of the cover plate 1, which will increase the difficulty of fitting the boss 5 and the mounting hole 6.

[0082] Therefore, as Figure 5 As shown, in this embodiment, the mounting hole 6 is designed as an elongated oval structure. Specifically, the cross-section of the mounting hole 6 along the center line perpendicular to the center line of the mounting hole 6 is an elongated oval. The elongated oval includes, in sequence, a first arc segment 63, a straight segment 64, and a second arc segment 65 in the wall thickness direction of the cover plate 1. The straight segment 64 is parallel to the wall thickness direction of the cover plate 1. The elongated oval structure of the mounting hole 6 effectively absorbs the tolerance in the bending height direction of the controller housing, compensates for dimensional errors in sheet metal processing, and ensures accurate alignment between the boss 5 and the mounting hole 6.

[0083] Furthermore, in this embodiment, the first side plate 2 and the connecting plate 4 have the same thickness, both being 1 mm. The outer diameter of the boss 5 is 3.5 mm, and the height of the boss 5 in the wall thickness direction of the first side plate 2 is 0.9 mm. The diameter of the first arc segment 63 and the second arc segment 65 is 3.6 mm, and the length of the straight segment 64 in the wall thickness direction of the cover plate 1 is 0.3 mm.

[0084] In other alternative embodiments, the preferred length of the straight segment 64 in the wall thickness direction of the cover plate 1 is 0.2~0.5mm. The diameters of the first arc segment 63 and the second arc segment 65 are designed according to the specific outer diameter of the boss 5. Preferably, the distance between the outer peripheral wall of the boss 5 and the mounting hole 6 corresponding to the inner wall surface of the straight segment 64 is 0.05~0.1mm, thereby ensuring a stable connection between the boss 5 and the mounting hole 6.

[0085] In other alternative implementations, when the thickness of the first side plate 2 and the connecting plate 4 is other values, before the boss 5 is riveted to the mounting hole 6, the outer diameter of the boss 5 is 2*t~5*t, and the height of the boss 5 in the wall thickness direction of the first side plate 2 is t~1.2*t; where t is the wall thickness of the second mounting plate.

[0086] This embodiment limits the size of the boss 5 to ensure that the boss 5 has sufficient deformation size, so that the boss 5 can be stably connected to the second mounting plate with mounting holes 6 after riveting deformation.

[0087] In this embodiment, the connecting plate 4 and the second side plate 3 are an integral structure, with the connecting plate 4 directly bent from the end of the second side plate 3. In other alternative embodiments, the connecting plate 4 can also be an independent structural component, meaning that the connecting plate 4 and the second side plate 3 are independent of each other and connected by a connecting structure. For example, the connecting plate 4 can be an L-shaped structural plate, with the two bent portions of the connecting plate 4 located on one side of the first side plate 2 in its wall thickness direction and on one side of the second side plate 3 in its wall thickness direction, respectively, to connect with the first side plate 2 and the second side plate 3, thereby fixing the first side plate 2 and the second side plate 3. The specific connection method of the connecting plate 4 and the second side plate 3 can refer to the connection method of the connecting plate 4 and the first side plate 2 described above.

[0088] In this embodiment, both the upper and lower housings of the controller housing can be made of the controller housing described above, which can further enhance the overall strength of the controller housing.

[0089] In this embodiment, the upper and lower housings of the controller housing are connected by fasteners such as bolts. In other alternative embodiments, the upper and lower housings of the controller housing can also be connected by riveting using the aforementioned central boss 5 and mounting holes 6.
