Description

Technical Field

[0001] The present application relates to the technical field of energy storage equipment, and in particular to a housing assembly and an energy storage power supply. Background Art

[0002] Mobile energy storage devices usually have some plug-in terminals for connecting to external devices. In the related art, when assembling the mobile energy storage device, the plug-in terminals are first fixed to the panel shell of the outer shell, and then the panel shell is connected to the bottom shell of the outer shell, and then the plug-in terminals and the circuit board of the mobile energy storage device are connected by wiring. This assembly method needs to consider the connection process between the plug-in terminal and the outer shell and the wiring process between the plug-in terminal and the circuit board, and has the disadvantages of high assembly cost and complicated assembly. Utility Model Content

[0003] In view of this, the present application provides a housing assembly and an energy storage power supply, which are beneficial to reducing assembly costs and simplifying assembly procedures.

[0004] One embodiment of the present application provides a shell assembly, which is applied to an energy storage power supply. A circuit board is provided inside the energy storage power supply. Plug terminals are provided on the circuit board. The shell assembly includes a main shell and a panel shell. The main shell is configured to accommodate the circuit board. And the main shell is provided with an assembly opening. The assembly opening has two first side edges and a second side edge located between the two first side edges. The panel shell is provided with a first limiting structure, a notch and two first snap-fit alignment structures. The first limiting structure is configured to rotate with the second side edge so that the panel shell can rotate relative to the main shell and cover the assembly opening. The two first snap-fit alignment structures are configured to respectively align with the two first side edges so that when the panel shell covers the assembly opening, the notch is adapted to the plug-in terminal and the plug-in terminal is exposed to the outside.

[0005] In the above embodiment, during the assembly process of the panel shell, the first limiting structure is rotated relative to the second side edge, so that the panel shell can be rotated toward the assembly opening, so that the first clamping alignment structure is aligned with the first side edge, thereby completing the assembly of the panel shell and the main shell, which is conducive to simplifying the assembly process. The first limiting structure and the first clamping alignment structure are limited and matched with different edges of the assembly opening, so that the panel shell is stably assembled in the assembly opening of the main shell. At the same time, through the limitation of the first clamping alignment structure, the relative position of the panel shell and the bottom shell can be corrected on the basis of the limitation of the first limiting structure, so that the notch is aligned with the position of the plug-in terminal, so that the plug-in terminal does not need to be fixed to the panel shell in advance, which is conducive to integrating the plug-in terminal directly on the circuit board, thereby eliminating the wiring process, thereby reducing the assembly cost and simplifying the assembly process.

[0006] In some embodiments of the present application, the first direction is defined as the distribution direction of the two first side edges. The second direction and the third direction are defined to intersect pairwise with the first direction. The first clamping and alignment structure is clamped with the first side edge along the second direction. The main housing is provided with a first limiting portion. The first limiting portion is located at the second side edge. The first limiting structure is inserted into the first limiting portion along the third direction. The first limiting portion stops the first limiting structure along the second direction.

[0007] In the above embodiments, during the assembly of the housing assembly, by inserting the first limiting structure into the first limiting portion, the panel housing originally separated from the main housing can be flipped relative to the main housing with the first limiting portion as a fulcrum, so as to rotate towards the assembly opening to complete the assembly. And in the clamping direction of the first clamping and alignment structure, the first limiting portion can stop the first limiting structure, which is beneficial to preventing the first clamping and alignment structure from separating from the first side edge and improving the firmness of the panel housing assembly.

[0008] In some embodiments of the present application, the first limiting portion includes a first convex edge and a first stop block. The first convex edge protrudes along the third direction. The first stop block is spaced from the first convex edge along the second direction and forms a first slot. Along the second direction, the first stop block is located inside the main housing compared with the first convex edge. The first limiting structure includes a first limiting wall and a first convex rib. The first convex edge stops the first limiting wall along the first direction. The first convex rib is connected to the first limiting wall. The first convex rib protrudes along the first direction and is inserted into the first slot.

[0009] In the above embodiments, by providing the first convex edge and the first stop block, the first convex rib can be inserted into the first slot, so as to stop the relative two sides of the first convex rib in the second direction, limit the first convex rib and make the axis of the panel housing rotation relatively stable, which is beneficial to the accurate alignment of the first clamping and alignment structure. And by the first convex edge stopping the first limiting wall, on the one hand, it can support the first limiting wall when the panel housing rotates to improve the rotation stability and accuracy, and on the other hand, it can limit the first limiting wall after the panel housing is assembled in place to make the relative assembly position of the panel housing and the main housing accurate, and improve the alignment accuracy of the notch and the insertion terminal.

[0010] In some embodiments of the present application, the distance of the first slot along the second direction is greater than the structural length of the first convex rib along the second direction.

[0011] In the above embodiments, the first slot provides a loose environment for the first convex rib in the second direction, so that the first convex rib can rotate in the first slot when the panel housing flips, which is beneficial to both restricting the position of the axis of the panel housing rotation and reducing the problems of blockage and jerks during the rotation of the panel housing.

[0012] In some embodiments of the present application, the first direction is defined as the distribution direction of the two first side edges. The second direction and the third direction are defined to intersect pairwise with the first direction. The first clamping alignment structure is clamped with the first side edge along the second direction. The panel housing is further provided with a clamping portion. The clamping portion is spaced from the first clamping alignment structure along the first direction. The clamping portion is spaced from the first limiting structure along the third direction. The clamping portion is configured to clamp the circuit board.

[0013] In the above embodiments, on the basis of accurate assembly of the panel housing and the main housing, the circuit board is clamped by the clamping portion, improving the accuracy of the assembly position of the panel housing and the circuit board, which is beneficial to improving the alignment accuracy between the notch and the plug-in terminal.

[0014] In some embodiments of the present application, the main housing is provided with two first clamping portions. Each first clamping portion is located at a first side edge. The first clamping portion and the first clamping alignment structure are mutually stopped along the first direction and the second direction. And the first clamping portion and the first clamping alignment structure are allowed to move relative to each other along the third direction.

[0015] In the above embodiments, the first clamping portion stops the first clamping alignment structure in the second direction, so that the panel housing can be connected to the main housing after being flipped in place towards the assembly opening. The first clamping portion stops the first clamping alignment structure in the first direction, so that the panel housing and the main housing are assembled in place in the first direction. And the first clamping alignment structure can move relative to the first clamping portion in the third direction, so as to eliminate the error brought in the third direction due to the rotation of the first limiting portion, which is beneficial to the clamping portion moving to the position where the circuit board can be accurately clamped.

[0016] In some embodiments of the present application, the first direction is defined as the distribution direction of the two first side edges, the second direction and the third direction are defined to intersect pairwise with the first direction. The first clamping alignment structure is clamped with the first side edge along the second direction. The housing assembly further includes a top shell. The top shell is connected to the main housing and is located on the same side of the main housing and the panel housing along the third direction. The top shell is provided with a second limiting portion along the third direction. The panel housing is further provided with a second limiting structure. The second limiting structure is inserted into the second limiting portion along the third direction. The second limiting portion stops the second limiting structure along the second direction.

[0017] In the above embodiments, after the top shell is connected to the main housing, through the insertion and cooperation of the second limiting portion and the second limiting structure, the panel housing and the top shell are accurately assembled. And in the clamping direction of the first clamping alignment structure, the second limiting portion can stop the second limiting structure, which is beneficial to preventing the first clamping alignment structure from disengaging from the first side edge and improving the firmness of the panel housing assembly.

[0018] In some embodiments of the present application, the second limiting portion includes a second convex edge and a second stop block. The second convex edge protrudes along the third direction. The second stop block is spaced apart from the second convex edge along the second direction and forms a second slot. The second limiting structure includes a second limiting wall and a second convex rib. The second convex edge stops the second limiting wall along the first direction. The second convex rib is connected to the second limiting wall. The second convex rib protrudes along the first direction and is plugged into the second slot.

[0019] In the above embodiment, by providing the second convex edge and the second stop block, the second convex rib can be inserted into the second slot, thereby stopping the opposite sides of the second convex rib in the second direction, limiting the second convex rib to constrain the axis of rotation of the panel shell to be relatively stable, which is conducive to the accurate alignment of the first clamping alignment structure. And by the second convex edge stopping the second limiting wall, after the panel shell is assembled in place, the second limiting wall can be limited to make the assembly position of the panel shell relative to the main shell accurate, thereby improving the alignment accuracy of the notch and the plug-in terminal.

[0020] In some embodiments of the present application, the distance of the second slot along the second direction is equal to the structural length of the second rib along the second direction.

[0021] In the above embodiment, the second slot provides a suitable insertion space for the second rib in the second direction, so that the second limiting portion accurately defines the position of the second limiting structure in the second direction, thereby improving the accuracy of the panel shell assembly position.

[0022] In some embodiments of the present application, the panel shell is further provided with a second clamping alignment structure. The top shell is provided with a second clamping portion. The second clamping alignment structure is clamped with the second clamping portion along a third direction.

[0023] In the above embodiment, the second snap-fit alignment structure is snap-fitted with the second snap-fit portion, so that the top shell is stably assembled with the panel shell in the third direction, thereby improving the firmness of the overall assembly of the shell structure.

[0024] An embodiment of the present application provides an energy storage power supply. The energy storage power supply includes a battery cell, a circuit board, and a housing assembly as described in any of the above embodiments. The battery cell and the circuit board are both arranged in the housing assembly. The plug-in terminal is exposed to the outside through a notch.

[0025] In the above embodiment, during the assembly process of the panel shell, the panel shell can rotate with one side of the assembly opening as a fulcrum, and then snap-fit with other side edges to complete the assembly, thereby simplifying the assembly process. In addition, through the limitation of the first snap-fit alignment structure, the relative position of the panel shell and the bottom shell can be corrected on the basis of the limitation of the first limiting structure, so that the notch and the position of the plug-in terminal are aligned, so that the plug-in terminal does not need to be fixed to the panel shell in advance, which is conducive to directly integrating the plug-in terminal on the circuit board, thereby eliminating the wiring process, thereby reducing the assembly cost and simplifying the assembly process.

[0046] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

It is only for the convenience of describing this 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 cannot be understood as a limitation of this application.

[0049] In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0050] Mobile energy storage devices usually have some plug - in terminals for connecting to external devices. In the related art, when assembling a mobile energy storage device, the plug - in terminals are first fixed to the panel shell of the housing, then the panel shell is connected to the bottom shell of the housing, and then the plug - in terminals and the circuit board of the mobile energy storage device are connected by wiring. This assembly method needs to consider the connection process of the plug - in terminals to the housing and the wiring process of the plug - in terminals to the circuit board, and has the defects of high assembly cost and cumbersome assembly.

[0051] An embodiment of the present application provides a shell assembly and an energy storage power supply. The shell assembly is applied to an energy storage power supply. A circuit board is provided inside the energy storage power supply. Plug terminals are provided on the circuit board. The shell assembly includes a main shell and a panel shell. The main shell is configured to accommodate the circuit board. And the main shell is provided with an assembly opening. The assembly opening has two first side edges and a second side edge located between the two first side edges. The panel shell is provided with a first limiting structure, a notch and two first snap-fit alignment structures. The first limiting structure is configured to rotate with the second side edge so that the panel shell can rotate relative to the main shell and cover the assembly opening. The two first snap-fit alignment structures are configured to respectively align with the two first side edges so that when the panel shell covers the assembly opening, the notch is adapted to the plug-in terminal and the plug-in terminal is exposed to the outside.

[0052] During the assembly process of the panel shell, the first limiting structure is rotated relative to the second side edge so that the panel shell can be rotated toward the assembly opening, so that the first clip-on alignment structure can be aligned with the first side edge, thereby completing the assembly of the panel shell and the main shell, which is conducive to simplifying the assembly process. The first limiting structure and the first clip-on alignment structure are limited and matched with different edges of the assembly opening, so that the panel shell can be stably assembled in the assembly opening of the main shell. At the same time, through the limitation of the first clip-on alignment structure, the relative position of the panel shell and the bottom shell can be corrected on the basis of the limitation of the first limiting structure, so that the notch is aligned with the position of the plug-in terminal, so that the plug-in terminal does not need to be fixed to the panel shell in advance, which is conducive to integrating the plug-in terminal directly on the circuit board, thereby eliminating the wiring process, thereby reducing the assembly cost and simplifying the assembly process.

[0053] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0054] See also Figure 1 One embodiment of the present application provides an energy storage power supply 200. The energy storage power supply 200 has the functions of storing and discharging electricity, and can be used for home backup power, production unit backup power, outdoor work, outdoor entertainment, etc.

[0055] It is understood that in some embodiments, the energy storage power supply 200 can be used independently and supply power to the power-consuming device. In other embodiments, the energy storage power supply 200 can be used in coordination with other energy storage devices as a power supply system that provides additional battery capacity.

[0056] See also Figures 1 to 3 In some embodiments, the energy storage power supply 200 includes a battery cell 201, a circuit board 202, and a housing assembly 100. The battery cell 201 and the circuit board 202 are both disposed in the housing assembly 100. The housing assembly 100 is used to protect the battery cell 201 and the circuit board 202.

[0057] It can be understood that in some embodiments, the circuit board 202 can be a BMS (Battery Management System) board or a PSDR (Power Supply Driver) board.

[0058] See Figure 1 and Figure 2 , in some embodiments, the circuit board 202 is provided with a plug-in terminal 203. The housing assembly 100 is provided with a notch 21. The plug-in terminal 203 is exposed to the outside through the notch 21. The energy storage power supply 200 is connected to an external device through the plug-in terminal 203.

[0059] It can be understood that in some embodiments, the plug-in terminal 203 can be various types of USB (Universal Serial Bus) interfaces, various types of audio interfaces, various types of optical fiber interfaces, etc.

[0060] See Figure 1 and Figure 2 , in some embodiments, the housing assembly 100 includes a main housing 10 and a panel housing 20. The main housing 10 is configured to accommodate the circuit board 202. And the main housing 10 is provided with an assembly opening 11. The panel housing 20 is assembled to the assembly opening 11. The panel housing 20 is provided with a notch 21 for the plug-in terminal 203 to be exposed.

[0061] See Figures 3 to 5 , in some embodiments, the circuit board 202 is fixedly connected to the main housing 10. The assembly opening 11 has two first side edges 111 and a second side edge 112 located between the two first side edges 111. The panel housing 20 is provided with a first limiting structure 22 and two first snap-fit alignment structures 23. The first limiting structure 22 is configured to rotatably cooperate with the second side edge 112 so that the panel housing 20 can rotate relative to the main housing 10 and cover the assembly opening 11. The two first snap-fit alignment structures 23 are configured to respectively align and cooperate with the two first side edges 111 so that when the panel housing 20 covers the assembly opening 11, the notch 21 is adapted to the plug-in terminal 203 and the plug-in terminal 203 is exposed to the outside.

[0062] During the assembly process of the panel shell 20, the first limiting structure 22 rotates relative to the second side edge 112, so that the panel shell 20 can rotate toward the assembly opening 11, so that the first clamping alignment structure 23 can be aligned with the first side edge 111, thereby completing the assembly of the panel shell 20 and the main shell 10, which is conducive to simplifying the assembly process. The first limiting structure 22 and the first clamping alignment structure 23 are limited and matched with different edges of the assembly opening 11, so that the panel shell 20 can be stably assembled in the assembly opening 11 of the main shell 10. At the same time, through the limitation of the first clamping alignment structure 23, the relative position of the panel shell 20 and the bottom shell can be corrected on the basis of the limitation of the first limiting structure 22, so that the notch 21 is aligned with the position of the plug-in terminal 203, so that the plug-in terminal 203 does not need to be fixed to the panel shell 20 in advance, which is conducive to directly integrating the plug-in terminal 203 on the circuit board 202, thereby eliminating the wiring process, thereby reducing the assembly cost and simplifying the assembly process.

[0063] It can be understood that in some embodiments, the structure where the two first side edges 111 and the second side edge 112 are located is an integrally formed structure. In other embodiments, the structure where the two first side edges 111 and the second side edge 112 are located can also be a split structure; for example, the main housing 10 includes a bottom housing and a side housing that can be detached from each other, then the second side edge 112 is located at the bottom housing, and the first side edge 111 is located at the side housing.

[0064] See also Figure 1 In some embodiments, the first direction is defined as the distribution direction of the two first side edges 111. The second direction and the third direction are defined to intersect with the first direction in pairs. The first direction is the direction parallel to X in the diagram, the second direction is the direction parallel to Y in the diagram, and the third direction is the direction parallel to Z in the diagram. For the convenience of referring to the diagram, the first direction is hereinafter represented by "first direction X", the second direction is hereinafter represented by "second direction Y", and the third direction is hereinafter represented by "third direction Z". Optionally, in some embodiments, the first direction X, the second direction Y and the third direction Z are mutually perpendicular in pairs.

[0065] See also Figures 3 to 5 In some embodiments, the first clamping alignment structure 23 is clamped with the first side edge 111 along the second direction Y, so that the panel housing 20 is assembled and fixed relative to the main housing 10 in the second direction Y.

[0066] See also Figures 3 to 5 In some embodiments, the main housing 10 is provided with a first limiting portion 12. The first limiting portion 12 is located at the second side edge 112. The first limiting structure 22 is plugged into the first limiting portion 12 along the third direction Z. The first limiting portion 12 stops the first limiting structure 22 along the second direction Y.

[0067] When the housing assembly 100 is assembled, by inserting the first limiting structure 22 into the first limiting portion 12, the panel housing 20 that was originally separated from the main housing 10 can be flipped relative to the main housing 10 with the first limiting portion 12 as a fulcrum, and thus rotate towards the assembly opening 11 to complete the assembly. And in the clamping direction of the first clamping and alignment structure 23, the first limiting portion 12 can stop the first limiting structure 22, which is beneficial to preventing the first clamping and alignment structure 23 from disengaging from the first side edge 111 and improving the firmness of the assembly of the panel housing 20.

[0068] See Figures 3 to 5 , in some embodiments, the first limiting portion 12 includes a first convex edge 121 and a first stop block 122. The first convex edge 121 protrudes along the third direction Z. The first stop block 122 is arranged at an interval from the first convex edge 121 along the second direction Y and forms a first slot 123. Along the second direction Y, the first stop block 122 is located inside the main housing 10 compared with the first convex edge 121. The first limiting structure 22 includes a first limiting wall 221 and a first rib 222. The first convex edge 121 stops the first limiting wall 221 along the first direction X. The first rib 222 is connected to the first limiting wall 221. The first rib 222 protrudes along the first direction X and is inserted into the first slot 123.

[0069] By providing the first convex edge 121 and the first stop block 122, the first rib 222 can be inserted into the first slot 123, so as to stop the relative two sides of the first rib 222 in the second direction Y, limit the first rib 222 and make the axis of rotation of the panel housing 20 relatively stable, which is beneficial to the accurate alignment of the first clamping and alignment structure 23. And by the first convex edge 121 stopping the first limiting wall 221, on the one hand, it can support the first limiting wall 221 when the panel housing 20 rotates to improve the rotation stability and accuracy, and on the other hand, it can limit the first limiting wall 221 after the panel housing 20 is assembled in place to make the assembly position of the panel housing 20 relative to the main housing 10 accurate and improve the alignment accuracy between the notch 21 and the plug-in terminal 203.

[0070] See Figures 3 to 5 , in some embodiments, the first convex edge 121 and the first limiting wall 221 extend in the first direction X, so as to improve the sealing effect at the first limiting structure 22 after the panel housing 20 is assembled. There are multiple first stop blocks 122, and each first stop block 122 protrudes along the third direction Z. The multiple first stop blocks 122 are spaced apart along the first direction X, which is beneficial to avoiding the cooperation between the first convex edge 121 and the first stop block 122 and the first rib 222 from being too tight, so as to allow the main housing 10 and the panel housing 20 to have a certain production tolerance. The first rib 222 extends in the first direction X to facilitate the cooperation with the multiple first stop blocks 122.

[0071] See Figure 3, optionally, in some embodiments, the first rib 222 abuts against the first stop block 122 along the second direction Y, so that the first clamping alignment structure 23 and the first side edge 111 are firmly connected in the second direction Y.

[0072] In other embodiments, the first stop block 122 can be omitted. The first slot 123 is formed on the side of the first flange 121 close to the inner side of the main housing 10 along the second direction Y. When the panel housing 20 is assembled, after the first rib 222 is inserted into the first slot 123, the first rib 222 and the first limiting wall 221 form a folded structure to hook the first flange 121, and then the panel housing 20 can rotate with the first flange 121 as a fulcrum.

[0073] See Figure 3 , in some embodiments, the distance of the first slot 123 along the second direction Y is greater than the structural length of the first rib 222 along the second direction Y.

[0074] The first slot 123 provides a loose environment for the first rib 222 in the second direction Y, so that the first rib 222 can rotate in the first slot 123 when the panel housing 20 is flipped. This is beneficial not only to restricting the position of the axis of rotation of the panel housing 20, but also to reducing the problems of blockage and jerks during the rotation of the panel housing 20.

[0075] In other embodiments, both the first slot 123 and the first rib 222 can be cylindrical structures extending along the first direction X, and the first slot 123 can be adapted to the first rib 222. The first rib 222 can be snapped into the first slot 123 perpendicular to the first direction X, so that while the first rib 222 can rotate in the first slot 123, the first slot 123 limits the first rib 222 perpendicular to the first direction X.

[0076] See Figure 3 and Figure 5 , in some embodiments, the panel housing 20 is further provided with a clamping portion 24. The clamping portion 24 is arranged at an interval from the first clamping alignment structure 23 along the first direction X. The clamping portion 24 is arranged at an interval from the first limiting structure 22 along the third direction Z. The clamping portion 24 is configured to clamp the circuit board 202.

[0077] On the basis that the panel housing 20 and the main housing 10 are accurately assembled, the circuit board 202 is clamped by the clamping portion 24, which improves the accuracy of the assembly position of the panel housing 20 and the circuit board 202, and is beneficial to improving the accuracy of the alignment between the notch 21 and the plug-in terminal 203.

[0078] See Figure 4 and Figure 5, in some embodiments, the main housing 10 is provided with two first latching portions 13. Each first latching portion 13 is located at a first side edge 111. The first latching portion 13 and the first latching alignment structure 23 are mutually stopped along the first direction X and the second direction Y. And the first latching portion 13 and the first latching alignment structure 23 are allowed to move relative to each other along the third direction Z. It can be understood that the circuit board 202 is extended and arranged perpendicular to the third direction Z, and the clamping portion 24 is configured to clamp the circuit board 202 along the third direction Z.

[0079] The first latching portion 13 stops the first latching alignment structure 23 in the second direction Y, so that the panel housing 20 can be connected to the main housing 10 after being flipped in place toward the assembly opening 11. The first latching portion 13 stops the first latching alignment structure 23 in the first direction X, so that the panel housing 20 and the main housing 10 are assembled in place in the first direction X. And the first latching alignment structure 23 can move relative to the first latching portion 13 in the third direction Z, so as to eliminate the error brought in the third direction Z due to the rotation of the first limiting portion 12, which is beneficial to the clamping portion 24 moving to the position where the circuit board 202 is accurately clamped.

[0080] See Figure 4 and Figure 5 , in some embodiments, the first latching alignment structure 23 is a hook-shaped structure, and the first latching portion 13 is a hole opened on the main housing 10. One side of the hook-shaped structure of the first latching alignment structure 23 has a protrusion along the first direction X, and after passing through the hole of the first latching portion 13 along the second direction Y, it hooks on the other side. Thus, the first latching portion 13 and the first latching alignment structure 23 are mutually stopped in the first direction X and the second direction Y. In other embodiments, the first latching portion 13 is a hook-shaped structure, and the first latching alignment structure 23 is a hole opened on the panel housing 20; or both the first latching portion 13 and the first latching alignment structure 23 are hook-shaped structures.

[0081] See Figure 3 , Figure 5 and Figure 6 , in some embodiments, the housing assembly 100 further includes a top shell 30. The top shell 30 is connected to the main housing 10 and is located on the same side of the main housing 10 and the panel housing 20 along the third direction Z. The top shell 30 is provided with a second limiting portion 31 along the third direction Z. The panel housing 20 is further provided with a second limiting structure 25. The second limiting structure 25 is inserted into the second limiting portion 31 along the third direction Z. The second limiting portion 31 stops the second limiting structure 25 in the second direction Y.

[0082] After the top shell 30 is connected to the main housing 10, through the insertion fit between the second limiting portion 31 and the second limiting structure 25, the panel shell 20 and the top shell 30 are accurately assembled. And in the clamping direction of the first clamping alignment structure 23, the second limiting portion 31 can stop the second limiting structure 25, which is beneficial to preventing the first clamping alignment structure 23 from detaching from the first side edge 111 and improving the firmness of the assembly of the panel shell 20.

[0083] It can be understood that in some embodiments, the first limiting structure 22 and the second limiting structure 25 are located at both ends of the panel shell 20 along the third direction Z.

[0084] See Figure 3 、 Figure 5 and Figure 6 As shown in, in some embodiments, the second limiting portion 31 includes a second convex edge 311 and a second stop block 312. The second convex edge 311 protrudes along the third direction Z. The second stop block 312 is spaced from the second convex edge 311 along the second direction Y and forms a second slot 313. The second limiting structure 25 includes a second limiting wall 251 and a second rib 252. The second convex edge 311 stops the second limiting wall 251 along the first direction X. The second rib 252 is connected to the second limiting wall 251. The second rib 252 protrudes along the first direction X and is inserted into the second slot 313.

[0085] By providing the second convex edge 311 and the second stop block 312, the second rib 252 can be inserted into the second slot 313, so as to stop the relative two sides of the second rib 252 in the second direction Y, limit the second rib 252 and make the axis of rotation of the panel shell 20 relatively stable, which is beneficial to the accurate alignment of the first clamping alignment structure 23. And by stopping the second limiting wall 251 with the second convex edge 311, after the panel shell 20 is assembled in place, the second limiting wall 251 can be limited to make the assembly position of the panel shell 20 relative to the main housing 10 accurate, and the alignment accuracy between the notch 21 and the plug-in terminal 203 is improved.

[0086] See Figure 3 、 Figure 5 and Figure 6 As shown in, in some embodiments, the second convex edge 311 and the second limiting wall 251 extend in the first direction X, so as to improve the sealing effect at the second limiting structure 25 after the panel shell 20 is assembled. There are multiple second stop blocks 312, and each second stop block 312 protrudes along the third direction Z. The multiple second stop blocks 312 are spaced along the first direction X, which is beneficial to avoiding the too tight fit between the second convex edge 311 and the second stop block 312 and the second rib 252, so as to allow the top shell 30 and the panel shell 20 to have a certain production tolerance. The second rib 252 extends in the first direction X to facilitate the cooperation with the multiple second stop blocks 312.

[0087] Optionally, in some embodiments, the second stopper 312 is located inside the housing structure along the second direction Y relative to the second flange 311. The second rib 252 abuts against the second stopper 312 along the second direction Y, so that the first snap alignment structure 23 and the first side edge 111 are firmly connected in the second direction Y.

[0088] See Figure 3 , in some embodiments, the distance of the second slot 313 along the second direction Y is equal to the structural length of the second rib 252 along the second direction Y. Herein, "equal to" means that on the premise that the second rib 252 can be inserted into the second slot 313, the second flange 311 and the second stopper 312 respectively abut against the second rib 252 along the second direction Y.

[0089] The second slot 313 provides just the right insertion space for the second rib 252 in the second direction Y, so that the second limiting portion 31 accurately limits the position of the second limiting structure 25 in the second direction Y, improving the accuracy of the assembly position of the panel housing 20.

[0090] See Figure 5 and Figure 6 , in some embodiments, the panel housing 20 is further provided with a second snap alignment structure 26. The top housing 30 is provided with a second snap portion 32. The second snap alignment structure 26 is snap-connected to the second snap portion 32 along the third direction Z.

[0091] The second snap alignment structure 26 and the second snap portion 32 are snap-connected and matched, so that the top housing 30 is stably assembled with the panel housing 20 in the third direction Z, improving the firmness of the overall assembly of the housing structure.

[0092] It can be understood that, in some embodiments, the top housing 30 and the main housing 10 are snap-connected to each other in the third direction Z, so that the top housing 30 and the main housing 10 are fixedly assembled.

[0093] See Figures 4 to 6 , in some embodiments, the assembly process of the energy storage power supply 200 is as follows:

[0094] Fix the circuit board 202 to the main housing 10. Insert the first rib 222 into the first slot 123, and with the first limiting structure 22 and the first limiting portion 12 as fulcrums, flip the panel housing 20 towards the assembly opening 11 until the first snap alignment structure 23 is snap-connected to the first snap portion 13 of the first side edge 111. While the first snap alignment structure 23 is snap-connected to the first snap portion 13, the clamping portion 24 rotates to be aligned with the circuit board 202 and clamp the circuit board 202. Insert the second limiting portion 31 of the top housing 30 into the second limiting structure 25 of the panel housing 20 to align the top housing 30 with the panel housing 20 and the main housing 10, and then snap-connect the top housing 30 with the panel housing 20 and the main housing 10. Thus, the assembly of the energy storage power supply 200 is completed.

As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present application, they fall within the scope of disclosure of the present application.
