Description

Technical Field

[0001] This application relates to the field of energy storage equipment technology, and in particular to a housing component and an energy storage device. Background Technology

[0002] Currently, energy storage equipment chassis typically have multiple removable covers. During later maintenance, operators can remove different covers to open corresponding areas inside the chassis for inspection and repair. For example, inverter chassis usually have an upper cover and a lower cover, which are positioned vertically. The external wiring ports of the inverter are concentrated in the area of ​​the lower cover. Operators can remove the lower cover to open the chassis and inspect and repair the inverter's wiring area. The chassis also requires welded crossbeams, located at the connection between the upper and lower covers. The upper and lower covers overlap and are fixed to the crossbeams to ensure the stability of the installation.

[0003] However, during the production and assembly of energy storage equipment, the presence of crossbeams can hinder the installation of electronic components inside the chassis. Furthermore, during later maintenance, the crossbeams can obscure some electronic components, making it difficult for operators to inspect the electronic components directly opposite the crossbeams, thus increasing the difficulty of after-sales maintenance.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0028] In the description of the embodiments in this application, the words "exemplary" or "for example" are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0029] Figure 1 This is a schematic diagram of the structure of the enclosure of an energy storage device in related technologies.

[0030] like Figure 1 As shown, the energy storage device's enclosure 101 typically has multiple removable covers. During later maintenance, operators can remove different covers to open the corresponding internal areas for inspection and repair. For example, the inverter's enclosure 101 usually has an upper cover and a lower cover. A crossbeam 102 is welded and fixed to the middle of the enclosure 101, and the upper and lower covers are respectively fixed to the enclosure 101, with the connection between the upper and lower covers overlapping and fixed to the crossbeam 102. The inverter's external wiring ports are centrally located in the area where the lower cover is located. Operators can remove the lower cover to open the enclosure 101 to inspect and repair the inverter's wiring area.

[0031] However, during the production and assembly of energy storage equipment, the crossbeam 102 is pre-welded to the middle of the housing 101. Therefore, the presence of the crossbeam 102 hinders the installation of electronic components 104 inside the housing 101. For example, when installing the circuit board 103 inside the housing 101, the circuit board 103 needs to be tilted and placed inside the housing 101 before being fixed to the bottom surface of the housing 101, affecting assembly efficiency and production benefits. Furthermore, during later maintenance, the crossbeam 102 will obstruct some of the electronic components 104, and it occupies internal space within the housing 101, making it difficult for operators to inspect the electronic components 104 inside the housing 101, increasing the difficulty of later maintenance.

[0032] Therefore, this application provides a housing component and energy storage device, which has the technical effects of facilitating assembly, improving production efficiency, and reducing the difficulty of later maintenance.

[0033] Figure 2 A schematic diagram of the structure of the housing assembly provided in this application. Figure 3 Exploded view of the chassis and support beam provided for this application.

[0034] like Figure 2 and Figure 3 As shown, this application embodiment first provides a housing assembly 100, which is applied to an energy storage device. The energy storage device can be a photovoltaic inverter, and includes electronic components and the housing assembly 100. The electronic components are disposed within the housing assembly 100, and the housing assembly 100 protects the electronic components. The electronic components include, but are not limited to, an inverter module, a control module, a battery management module, passive components (such as capacitors and inductors), and sensors, which can be configured according to the actual application scenario.

[0035] The enclosure assembly 100 includes a chassis 10, a first cover plate 20, a second cover plate 30, and a support beam 40. The chassis 10 has a receiving cavity 11, with an opening formed on its surface. The first cover plate 20 and the second cover plate 30 are both disposed on the chassis 10, arranged side-by-side, and cooperate to cover the opening of the receiving cavity 11. The support beam 40 is disposed on the chassis 10, located between the first cover plate 20 and the second cover plate 30, and connected to both. A detachable component 50 is provided at the end of the support beam 40, allowing for detachable connection between the support beam 40 and the chassis 10.

[0036] Understandably, the support beam 40 in this application is fixed to the chassis 10 in a reusable and reassembleable manner, replacing the non-reusable welding fixing method in related technologies. During production assembly, operators can first install the electronic components into the receiving cavity 11 of the chassis 10, then overlap the support beam 40 onto the chassis 10, and fix the support beam 40 to the chassis 10 using the disassembly / reassembly component 50. Finally, the first cover plate 20 and the second cover plate 30 are installed on the chassis 10 and the support beam 40. This avoids the pre-fixed support beam 40 obstructing the installation process of the electronic components, facilitating installation and improving assembly efficiency and production effectiveness.

[0037] In later maintenance, if it is necessary to inspect and repair the electronic components inside the chassis 10, the operator can remove the support beam 40 from the chassis 10 through the disassembly and assembly part 50, so as to avoid the support beam 40 from blocking the accommodating cavity 11 and electronic components, providing more operating space inside the chassis 10 and reducing the difficulty of later maintenance.

[0038] Figure 4 A cross-sectional view of the housing assembly provided in this application.

[0039] Please refer to the following: Figure 4 In some embodiments, the first cover plate 20 and the second cover plate 30 are detachably connected to the chassis 10, and the first cover plate 20 and the second cover plate 30 are distributed along a first direction. Exemplarily, the first direction is the X direction shown in the figure. Under normal use, the first direction is parallel to the vertical direction, and the first cover plate 20 is located below the second cover plate 30. The position of the first cover plate 20 can be configured according to the position of the interface terminals of the electronic components. Thus, by removing the first cover plate 20, the operator can open the area of ​​the chassis 10 near the interface terminals and directly inspect the wiring of the interface terminals, facilitating later maintenance.

[0040] Figure 5 A schematic diagram of the structure of the first cover plate provided in this application.

[0041] Please refer to the following: Figure 5 In some embodiments, the first cover plate 20 is rectangular in shape, and a first folded edge 21 is provided on the side of the first cover plate 20 facing the second cover plate 30. The first folded edge 21 is bent relative to the first cover plate 20 and is used to cooperate with and fix the second cover plate 30.

[0042] A first sealing ring 22 is provided on the side of the first cover plate 20 facing the chassis 10. The first sealing ring 22 is disposed between the first cover plate 20, the chassis 10 and the support beam 40 to seal the gap between the first cover plate 20, the chassis 10 and the support beam 40, thereby improving the sealing performance of the first cover plate 20.

[0043] In some embodiments, the first cover plate 20 is bolted to the chassis 10 and the support beam 40, so that the first cover plate 20 is detachably fixed to the chassis 10. Exemplarily, the first cover plate 20 is provided with a first fixing screw 23 and a second fixing screw 24. The first fixing screw 23 is located on the side of the first cover plate 20 closest to the support beam 40, and the second fixing screw 24 is located on the side of the first cover plate 20 furthest from the support beam 40. The first cover plate 20 has a first opening 25 for the first fixing screw 23 to pass through, and a second opening 26 for the second fixing screw 24 to pass through. The first fixing screw 23 passes through the first cover plate 20 and is threadedly connected to the support beam 40. The second fixing screw 24 passes through the first cover plate 20 and is threadedly connected to the chassis 10.

[0044] For example, the first fixing screw 23 and the second fixing screw 24 are both arranged in pairs, and the two first fixing screws 23 and the two second fixing screws 24 are distributed at the four corners of the first cover plate 20, which can improve the installation stability of the first cover plate 20.

[0045] When it is necessary to remove the first cover plate 20, the first fixing screw 23 and the second fixing screw 24 can be removed from the first cover plate 20 to open the first cover plate 20. When it is necessary to install the first cover plate 20, the first cover plate 20 can be overlapped on the support beam 40 and the chassis 10, and the first cover plate 20 can be fixed by the first fixing screw 23 and the second fixing screw 24.

[0046] It is understood that in the example of this application, the first cover plate 20 is detachably fixed by bolting. In other embodiments, the first cover plate 20 can also be detachably fixed by snap-fit, interference fit, pin fit, etc. This application does not limit this.

[0047] Figure 6 A schematic diagram of the structure of the second cover plate provided in this application.

[0048] Please refer to the following: Figure 6 In some embodiments, the second cover plate 30 is rectangular in shape, and a second folded edge 31 is provided on the side of the second cover plate 30 facing the first cover plate 20. The second folded edge 31 is bent relative to the second cover plate 30 and is used to cooperate with and fix the first folded edge 21 of the first cover plate 20.

[0049] A second sealing ring 32 is provided on the side of the second cover plate 30 facing the chassis 10. The second sealing ring 32 is disposed between the second cover plate 30, the chassis 10 and the support beam 40 to seal the gap between the second cover plate 30, the chassis 10 and the support beam 40, thereby improving the sealing performance of the second cover plate 30.

[0050] In some embodiments, the second cover plate 30 is bolted to the chassis 10 to allow for detachable fixation. Exemplarily, a locking stud 33 is provided on the side of the second cover plate 30 facing the chassis 10, and the locking stud 33 is riveted to the second cover plate 30. Multiple locking studs 33 are distributed on the side of the second cover plate 30 away from the second flange 31, and also distributed in the middle of the second cover plate 30. Each locking stud 33 is equipped with a locking screw 34. The locking screw 34 passes through the chassis 10 and is threadedly connected to the locking stud 33 to fix the second cover plate 30 to the chassis 10.

[0051] Figure 7 A partial schematic diagram of the cross-sectional view of the housing assembly provided in this application.

[0052] Please refer to the following: Figure 7 In some embodiments, the first folded edge 21 is provided with a positioning pin 211, and the second folded edge 31 is provided with a positioning hole 311, into which the positioning pin 211 is inserted. Exemplarily, multiple positioning pins 211 are provided, spaced apart along the length of the first folded edge 21. The positioning pins 211 are riveted to the first folded edge 21, and protrude relative to the first folded edge 21 along a first direction. The second folded edge 31 has multiple positioning holes 311, corresponding to multiple positioning pins 211, with each positioning pin 211 inserted into its corresponding positioning hole 311.

[0053] Thus, the edge of the first cover plate 20 near the first folded edge 21 can be fixed to the support beam 40 by the first fixing screw 23, and the second cover plate 30 can be fixed by the engagement of the positioning pin 211 and the positioning hole 311. The remaining edges of the first cover plate 20, excluding the first folded edge 21, can be fixed to the chassis 10 by the second fixing screw 24. The edge of the second cover plate 30 near the second folded edge 31 can be fixed to the first cover plate 20 by the engagement of the positioning pin 211 and the positioning hole 311, and the remaining edges of the second cover plate 30, excluding the second folded edge 31, can be fixed to the chassis 10 by the locking stud 33.

[0054] It is understandable that by utilizing the positioning fit between the positioning pin 211 and the positioning hole 311, the connection strength between the first cover plate 20 and the second cover plate 30 at the support beam 40 can be enhanced, while saving the use of screw structures and reducing material costs.

[0055] On the other hand, when it is necessary to disassemble the first cover plate 20, the first fixing screw 23 and the second fixing screw 24 can be removed first, and then the first cover plate 20 can be pulled to disengage the positioning pin 211 from the positioning hole 311, thereby releasing the positioning fit between the first cover plate 20 and the second cover plate 30. When it is necessary to install the first cover plate 20, the positioning pin 211 can be inserted into the positioning hole 311 after the second cover plate 30 has been installed in the chassis 10, and then the first cover plate 20 can be fixed by the first fixing screw 23 and the second fixing screw 24. In this way, the first cover plate 20 can be disassembled and installed independently without the participation of the second cover plate 30, reducing the number of operation steps and lowering the difficulty of disassembly and assembly.

[0056] In some embodiments, the second cover plate 30 is further provided with a third folded edge 35 on the side facing the first cover plate 20. The third folded edge 35 is formed by bending from the side of the second folded edge 31 away from the second cover plate 30, and the third folded edge 35 is parallel to the second cover plate 30. The third folded edge 35 has a plurality of connecting holes 351 for screws to pass through. The third folded edge 35 is used to overlap and fix with the support beam 40, thereby improving the connection strength between the second cover plate 30 and the support beam 40.

[0057] Figure 8 This is a structural diagram of the chassis provided in this application.

[0058] Please refer to the following: Figure 8 In some embodiments, the chassis 10 is generally rectangular, and an accommodating cavity 11 is formed inside the chassis 10. The accommodating cavity 11 forms an opening on the front of the chassis 10. It is understood that the front of an object mentioned in this application refers to the side of the object facing the user during normal use, and the back of an object refers to the side of the object away from the user during normal use.

[0059] The front of the chassis 10 is provided with a support plate 12. The support plate 12 is distributed around the cavity opening and is riveted to the edge of the chassis 10. The support plate 12 is used to provide a space for the first cover plate 20, the second cover plate 30 and the support beam 40 to overlap, so as to support the first cover plate 20, the second cover plate 30 and the support beam 40.

[0060] For example, the chassis 10 is provided with a plurality of fixing holes 13, and the plurality of fixing holes 13 are correspondingly provided with a plurality of second fixing screws 24. The fixing holes 13 are formed in the support plate 12, and the support plate 12 is riveted to the fixing holes 13 to fix a fixing nut. The second fixing screws 24 pass through the front of the first cover plate 20 and the support plate 12, and are threadedly connected to the fixing nut to fix the first cover plate 20 to the chassis 10. In this way, the first fixing screws 23 and the second fixing screws 24 can be installed or removed from the front of the first cover plate 20, which is convenient for operation.

[0061] For example, the chassis 10 is provided with a plurality of locking holes 14, which are correspondingly provided with a plurality of locking studs 33. Locking screws 34 pass through the back of the support plate 12 into the locking holes 14 and are threadedly connected to the locking studs 33 to fix the second cover plate 30 to the chassis 10. In this way, all the locking screws 34 can be hidden on the back of the second cover plate 30, protecting the appearance integrity of the chassis structure.

[0062] Figure 9 A structural schematic diagram of the support beam provided in this application.

[0063] Please refer to the following: Figure 9 In some embodiments, the support beam 40 is arranged parallel to the second direction, with an angle between the first and second directions. The second direction is the Y-direction shown in the figure. Under normal use, the second direction is parallel to the horizontal direction. The support beam 40 spans the opening of the accommodating cavity 11 in the second direction, and both ends of the support beam 40 are respectively overlapped and fixed to the housing 10. The connection between the first cover plate 20 and the second cover plate 30 is overlapped and fixed to the support beam 40 to prevent the connection between the first cover plate 20 and the second cover plate 30 from being suspended in the accommodating cavity 11, thereby improving the structural strength and installation stability of the first cover plate 20 and the second cover plate 30.

[0064] In some embodiments, the mounting component 50 includes a mounting stud 51 and a mounting screw 52, ​​and the chassis 10 is provided with a through hole 15. The mounting stud 51 passes through the through hole 15 and is threadedly connected to the mounting screw 52.

[0065] For example, the chassis 10 is provided with a recessed portion 16, which is formed by the support piece 12 being bent inward in a direction away from the opening of the receiving cavity 11. The support piece 12 has recessed portions 16 at both ends of the support beam 40. The recessed portions 16 are used to receive and position the support beam 40. A through hole 15 is formed in the bottom wall of the recessed portion 16, and a mounting stud 51 is fixed to the side of the support beam 40 facing the receiving cavity 11.

[0066] When the support beam 40 needs to be installed, the end of the support beam 40 can be overlapped and accommodated in the groove 16, allowing the mounting stud 51 to pass through the through hole 15, thus achieving initial positioning of the support beam 40. Then, the mounting screw 52 is threaded from the back of the support piece 12 to the mounting stud 51, so that the support beam 40 is completely fixed in the groove 16. When the support beam 40 needs to be disassembled, the mounting screw 52 can be unscrewed from the mounting stud 51, and then the end of the support beam 40 can be pulled out of the groove 16.

[0067] Understandably, the mounting stud 51 can cooperate with the through hole 15 to position the end of the support beam 40 in the groove 16, and can also cooperate with the mounting screw 52 to completely fix the support beam 40 in the groove 16. This facilitates the installation of the support beam 40 and improves the connection strength of the support beam 40.

[0068] In the example of this application, multiple mounting studs 51 are provided at both ends of the support beam 40, and the multiple mounting studs 51 are spaced apart in a first direction. For example, two mounting studs 51 are provided at each end of the support beam 40. Correspondingly, the chassis 10 is provided with a corresponding number of through holes 15 and a corresponding number of mounting screws 52. This improves the stability of the support beam 40 and enhances the support strength of the support beam 40 for the first cover plate 20 and the second cover plate 30.

[0069] It is understood that in the example of this application, the support beam 40 is detachably fixed by bolting. In other embodiments, the support beam 40 can also be detachably fixed by snap-fit, interference fit, pin fit, etc. This application does not limit this.

[0070] In some embodiments, the support beam 40 is provided with a mounting groove 46, which forms a slot on the side of the support beam 40 away from the mounting stud 51. A first flange 21, a second flange 31, and a third flange 35 pass through the slot and are received within the mounting groove 46, and a first cover plate 20 and / or a second cover plate 30 are fixed to the support beam 40.

[0071] For example, both the first cover plate 20 and the second cover plate 30 are fixed to the support beam 40. Specifically, the first cover plate 20 is bolted to the support beam 40 by a first fixing screw 23, and the second cover plate 30 is bolted to the support beam 40 by a third folded edge 35.

[0072] Thus, the side of the first cover plate 20 closest to the second cover plate 30 overlaps with the support beam 40, and the side of the second cover plate 30 closest to the first cover plate 20 overlaps with the support beam 40. The first folded edge 21 and the second folded edge 31 extend into the mounting groove 46 to complete the positioning fit. Both the first cover plate 20 and the second cover plate 30 are fixed to the support beam 40, so that the support beam 40 can simultaneously perform the functions of overlapping support, positioning fit, and bolting fixation for the first cover plate 20 and the second cover plate 30. While ensuring structural strength, the support and fixing structure is simplified, material costs are reduced, and space utilization is improved.

[0073] Specifically, the support beam 40 has a base plate 41, a first side plate 42, a second side plate 43, a first retaining edge 44, and a second retaining edge 45. The first side plate 42 and the second side plate 43 are disposed on both sides of the base plate 41 in a first direction, the first retaining edge 44 is disposed on the side of the first side plate 42 away from the base plate 41, and the second retaining edge 45 is disposed on the side of the second side plate 43 away from the base plate 41.

[0074] Thus, the base plate 41 forms the back portion of the support beam 40, the first flange 44 and the second flange 45 form the front portion of the support beam 40, and the first side plate 42 and the second side plate 43 form the side portion of the support beam 40. The base plate 41, the first side plate 42, the second side plate 43, the first flange 44 and the second flange 45 together form an mounting groove 46, and the first flange 44 and the second flange 45 are spaced apart to form a slot.

[0075] For example, the mounting studs 51 are riveted to the side of the base plate 41 opposite to the mounting groove 46, and each base plate 41 is provided with two mounting studs 51. The mounting studs 51 protrude from the surface of the base plate 41 so that the mounting studs 51 can be inserted into the through holes 15 of the recess 16.

[0076] For example, the support beam 40 can be formed by bending. The first side plate 42 and the second side plate 43 form an angle with the bottom plate 41, and the distance between the first side plate 42 and the second side plate 43 gradually increases in the direction away from the bottom plate 41. The shape of the groove portion 16 corresponds to the shape of the support beam 40, and the distance between the two sides of the groove portion 16 gradually increases in the direction away from the bottom wall of the groove.

[0077] Understandably, the support beam 40 adopts a wedge-shaped structure on the side, which facilitates the insertion of the support beam 40 into the groove 16, and increases the contact area between the side of the support beam 40 and other structures (such as sealing structures, support structures, etc.), thereby improving sealing performance and support strength.

[0078] For example, the first retaining edge 44 is provided with a mounting nut 47, which is correspondingly provided with the first fixing screw 23. The mounting nut 47 is riveted and fixed to the first retaining edge 44. The first fixing screw 23 passes through the first cover plate 20 and is threadedly connected to the mounting nut 47 to fix the first cover plate 20 to the support beam 40.

[0079] For example, the base plate 41 is provided with a connecting nut 48, which is correspondingly provided with the connecting hole 351, and the connecting nut 48 is riveted and fixed to the base plate 41. The third folded edge 35 is provided with a connecting screw, which passes through the connecting hole 351 and is threadedly connected to the connecting nut 48 to fix the second cover plate 30 to the support beam 40.

[0080] For example, both the first retaining edge 44 and the second retaining edge 45 are parallel to the base plate 41. The first retaining edge 44 is parallel to the first cover plate 20, and the second retaining edge 45 is parallel to the second cover plate 30. In this way, the contact area between the first cover plate 20, the second cover plate 30 and the support beam 40 can be increased, thereby improving the support strength of the support beam 40 for the first cover plate 20 and the second cover plate 30.

[0081] Figure 10 This is a structural schematic diagram of the seal provided in this application.

[0082] Please refer to the following: Figure 10 In some embodiments, a sealing element 60 is provided between the support beam 40, the chassis 10, the first cover plate 20, and the second cover plate 30. The sealing element 60 is located at both ends of the support beam 40 and is bonded and fixed to the support beam 40. The sealing element 60 is used to improve the sealing performance at the connection between the first cover plate 20 and the second cover plate 30, thereby enhancing the equipment's sealing level.

[0083] For example, the seal 60 may be integrally formed from an elastic material. The seal 60 has a connecting section 61, a first section 62, and a second section 63, wherein the first section 62 and the second section 63 are disposed on both sides of the connecting section 61. The connecting section 61 is disposed between the bottom surface of the support beam 40 and the chassis 10, the first section 62 is disposed between one side of the support beam 40 and the chassis 10, and the second section 63 is disposed between the other side of the support beam 40 and the chassis 10. The first section 62 is provided with a first extension 64, which is disposed between the support beam 40 and the first sealing ring 22. The second section 63 is provided with a second extension 65, which is disposed between the support beam 40 and the second sealing ring 32.

[0084] For example, the connecting section 61 is disposed between the base plate 41 and the bottom wall of the groove portion 16, so that the bottom of the support beam 40 and the bottom wall of the groove portion 16 cooperate to compress the sealing member 60, thereby achieving a large-area seal on the bottom surface. The position of the connecting section 61 is staggered from the position of the mounting stud 51 to avoid the sealing member 60 affecting the positioning and installation of the support beam 40.

[0085] For example, the shape of the seal 60 corresponds to the shape of the support beam 40. The side of the seal 60 adopts a wedge-shaped structure, that is, the first segment 62 and the second segment 63 form an angle with the connecting segment 61, and the distance between the first segment 62 and the second segment 63 gradually increases in the direction away from the connecting segment 61. The first segment 62 is disposed between the first side plate 42 and one of the groove walls of the groove portion 16, and the second segment 63 is disposed between the second side plate 43 and the other groove wall of the groove portion 16. In this way, the two side walls of the support beam 40 cooperate with the two groove walls of the groove portion 16 to compress the seal 60, thereby achieving a large-area seal on the side portion.

[0086] It is understandable that by utilizing the inclined surface fit between the side wall of the support beam 40, the groove wall of the groove portion 16, and the side of the seal 60, the contact area between the three can be increased, thereby improving the sealing performance and support strength.

[0087] For example, a first extension 64 is formed at the end of the first segment 62 away from the connecting segment 61. The first extension 64 is exposed in the recess 16 and extends along the first direction to the surface of the support piece 12 and the surface of the first retaining edge 44, and is pressed against the first sealing ring 22 to seal the gap between the first cover plate 20 and the support beam 40.

[0088] For example, a second extension 65 is formed at the end of the second segment 63 away from the connecting segment 61. The second extension 65 is exposed in the groove 16 and extends along the second direction to the surface of the support piece 12 and the surface of the second flange 45, and forms mutual compression with the second sealing ring 32 to seal the gap between the second cover plate 30 and the support beam 40.

[0089] It is understood that the sealing element 60 in this application can contact the first cover plate 20, the second cover plate 30, the support beam 40 and the chassis 10 at multiple positions respectively, and form a seal by extruding at different positions or angles, so as to meet the sealing processing tolerances and assembly process requirements between the first cover plate 20, the second cover plate 30, the support beam 40 and the chassis 10, and ensure that the sealing effect of the equipment is still met under the premise that the support beam 40 can be repeatedly disassembled and reassembled, thereby improving the durability and working stability of the equipment.
