Description

Technical Field

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

[0002] Mobile energy storage devices usually have plug-in terminals electrically connected to an external structure. The plug-in terminals are exposed to the outside through openings on the device housing. During the device assembly process, the alignment problem between the plug-in terminals and the housing openings is involved. In the related art, either the plug-in terminals are first assembled on the housing and then the plug-in terminals are connected to the circuit board, but the narrow space is not convenient for the connection between the plug-in terminals and the circuit board, which will result in a low overall assembly efficiency of the device; or the plug-in terminals are first connected to the circuit board and then the plug-in terminals are assembled with the housing, but the alignment accuracy requirements for the plug-in terminals and the housing openings are relatively high, also resulting in a low overall assembly efficiency of the device. Summary of the Utility Model

[0003] In view of this, the present application provides a housing assembly and an energy storage power supply, which can not only improve the assembly efficiency but also ensure the alignment accuracy between the plug-in terminals and the housing assembly.

[0004] An embodiment of the present application provides a housing assembly applied to an energy storage power supply. The energy storage power supply includes a circuit board. The circuit board is provided with plug-in terminals. The housing assembly includes a main housing and a panel housing. The main housing is configured to fixedly place the circuit board. And the main housing is provided with an assembly notch. The panel housing is provided with an avoidance opening and is formed with a clamping portion and a clamping connection portion. The clamping portion is configured to synchronously clamp the circuit board during the process of assembling the panel housing into the assembly notch, so as to restrict the movement of the panel housing relative to the circuit board in a first direction. The clamping connection portion is configured to synchronously clamp-connect to the edge of the assembly notch during the process of assembling the panel housing into the assembly notch, so as to restrict the movement of the panel housing relative to the circuit board in a second direction. An included angle is formed between the first direction and the second direction. The avoidance opening is configured to be adapted to the plug-in terminals after the panel housing is assembled into the main housing, so as to expose the plug-in terminals to the outside.

[0005] In the above embodiments, during the process of assembling the panel housing into the assembly notch, the clamping portion is clamped with the edge of the assembly notch, so that the panel housing is fixed to the main housing. The circuit board is fixed inside the main housing. While the clamping portion clamps the edge of the assembly notch, the clamping portion can synchronously clamp the circuit board, so that when the panel housing is fixed to the main housing, it is synchronously fixed to the circuit board. And the clamping portion positions the panel housing relative to the circuit board in the first direction, and the clamping portion positions the panel housing relative to the circuit board in the second direction. When the panel housing is fixed to the circuit board, the panel housing is synchronously positioned relative to the circuit board in a two-dimensional space, so that the insertion terminals assembled on the circuit board are positioned in a two-dimensional space with the avoidance openings formed in the panel housing. Therefore, the insertion terminals can be exposed to the outside through the avoidance openings for the energy storage power supply to be connected to external devices. And the positioning of the insertion terminals and the avoidance openings is carried out synchronously with the assembly of the panel housing to the main housing. Therefore, while ensuring the alignment accuracy between the housing assembly and the insertion terminals, the assembly efficiency is improved by eliminating additional positioning operations.

[0006] In some embodiments of the present application, the panel housing includes a panel body. The panel body is provided with avoidance openings. The clamping portion is connected to the panel body. The minimum distance between the range of the connection surface of the clamping portion on the panel body and the coverage range of the avoidance openings on the panel body is less than or equal to the maximum distance within the range of the connection surface of the clamping portion on the panel body.

[0007] In the above embodiments, by restricting the positional relationship between the clamping portion and the avoidance openings on the panel body, the clamping portion is close to the avoidance openings and the insertion terminals, so as to reduce the influence of the deformation of the circuit board itself on the alignment accuracy of the insertion terminals and the avoidance openings, which is beneficial to improving the alignment and adaptation accuracy between the housing assembly and the insertion terminals.

[0008] In some embodiments of the present application, the clamping portion is provided with a clamping groove and a guiding surface. The clamping groove is configured to synchronously receive the insertion of the circuit board during the process of assembling the panel housing into the assembly notch. The guiding surface is connected to the groove wall of the clamping groove. The guiding surface is configured to be located on at least one side of the clamping portion facing the circuit board in the first direction. And the guiding surface is configured to gradually approach the circuit board along the direction in which the circuit board is inserted into the clamping groove.

[0009] In the above embodiments, the circuit board is inserted into the clamping groove so that the clamping portion clamps the circuit board. The clamping portion clamps the circuit board in the first direction to restrict the relative position between the panel housing and the circuit board in the first direction. By providing the guiding surface, the clamping portion can guide the circuit board away from the clamping groove in the first direction to be close to the clamping groove, so as to reduce the alignment movement between the clamping portion and the circuit board in the first direction, which is beneficial to the clamping portion clamping the circuit board synchronously while the clamping portion clamps the edge of the assembly notch, thereby improving the assembly efficiency.

[0010] In some embodiments of the present application, the clamping portion is configured to be movable relative to the edge of the assembly notch in the first direction.

[0011] In the above embodiments, the main housing fixes the circuit board. By adjusting the position of the clamping portion relative to the edge of the assembly notch along the first direction, the clamping portion can move relative to the circuit board along the first direction, which is beneficial to accurately clamp the circuit board along the first direction so that the avoidance opening and the plug-in terminal are accurately aligned and adapted in the first direction.

[0012] In some embodiments of the present application, the clamping portion is provided with a clamping groove. The clamping groove is configured to synchronously supply the circuit board to be inserted during the process of assembling the panel housing into the assembly notch. The panel housing is further provided with a limiting portion. The limiting portion is at least partially disposed in the clamping groove. The limiting portion is configured to stop the circuit board along the direction in which the circuit board is inserted into the clamping groove, so that the plug-in terminal and the edge of the avoidance opening are spaced apart along the direction in which the circuit board is inserted into the clamping groove.

[0013] In the above embodiments, the circuit board is inserted into the clamping groove so that the clamping portion clamps the circuit board. As the circuit board is inserted into the clamping groove, the plug-in terminal gradually approaches the avoidance opening. By providing the limiting portion, the insertion depth of the circuit board in the clamping groove is restricted, so that the plug-in terminal is separated from the panel housing. If the energy storage power supply encounters scenarios such as dropping or collision, the panel housing directly impacts or applies a force to the circuit board rather than the plug-in terminal, which is beneficial to avoid the plug-in terminal being separated from the circuit board due to impact, thereby protecting the safety of the plug-in terminal.

[0014] In some embodiments of the present application, the limiting portion is configured to be spaced apart from the circuit board along the direction in which the circuit board is inserted into the clamping groove. And along the direction in which the clamping groove is for inserting the circuit board, the limiting portion is configured to have a distance from the circuit board greater than the distance between the edge of the avoidance opening and the plug-in terminal.

[0015] In the above embodiments, along the direction in which the circuit board is inserted into the clamping groove, the limiting portion does not directly abut against the circuit board, so as to provide redundancy between the assembly of the panel housing and the main housing and the assembly of the panel housing and the circuit board, which is beneficial to reducing the production operation requirements and thus reducing the production cost. At the same time, along the direction in which the circuit board is inserted into the clamping groove, by controlling the distance between the plug-in terminal and the avoidance opening to be greater than the distance between the circuit board and the limiting portion, it is ensured that the circuit board contacts the panel housing before the plug-in terminal, thereby protecting the safety of the plug-in terminal.

[0016] In some embodiments of the present application, the limiting portion and / or the clamping portion are provided with a limiting surface. The limiting surface is configured to abut against the mating surface of the circuit board along the second direction.

[0017] In the above embodiments, the limiting surface abuts against the mating surface in the second direction. On the one hand, on the basis of the positioning of the clamping portion in the second direction, the positioning accuracy of the panel housing relative to the circuit board is further improved, which is beneficial to improving the alignment and adaptation accuracy between the plug-in terminal and the avoidance opening. On the other hand, when the clamping portion fails to limit the panel housing in the second direction, the panel housing can be assisted in being limited, so as to maintain the adaptation between the plug-in terminal and the avoidance opening.

[0018] In some embodiments of the present application, the limiting portion is configured to be elastically deformed under the extrusion of the circuit board.

[0019] In the above embodiments, when the energy storage power supply encounters scenarios such as dropping or collision, or when the circuit board is inserted into the clamping groove, the limiting portion can absorb the impact between the panel housing and the circuit board through elastic deformation, and provide a buffer for the movement or movement tendency of the circuit board along the direction of inserting into the clamping groove, thereby protecting the safety between the panel housing and the circuit board.

[0020] In some embodiments of the present application, the clamping portion has a first buffer layer and a second buffer layer. The first buffer layer and the second buffer layer are arranged oppositely along the first direction and are configured to abut against the circuit board respectively. Both the first buffer layer and the second buffer layer are configured to be elastically deformed under the extrusion of the circuit board. When no circuit board is inserted between the first buffer layer and the second buffer layer, in the first direction, the distance between the first buffer layer and the second buffer layer is configured to be less than or equal to the thickness of the circuit board.

[0021] In the above embodiments, the clamping portion clamps and limits the circuit board in the first direction. By providing the first buffer layer and the second buffer layer, on the one hand, the production error between the clamping portion and the thickness of the circuit board in the first direction can be eliminated through elastic deformation, so as to avoid the generation of a gap between the clamping portion and the circuit board in the first direction, which reduces the alignment accuracy between the plug-in terminal and the avoidance opening, and avoid the generation of a negative gap between the clamping portion and the circuit board in the first direction, which makes it impossible to clamp the circuit board or damage the circuit board, thereby being beneficial to reducing the production operation requirements and production costs. On the other hand, the impact between the clamping portion and the circuit board can be absorbed through elastic deformation, and a buffer is provided for the movement tendency of the circuit board in the first direction, thereby protecting the safety between the clamping portion and the circuit board.

[0022] In some embodiments of the present application, the clamping portion includes a clamping sub-portion and a connecting portion. There are a plurality of clamping sub-portions, which are spaced apart along the second direction. The connecting portion connects two adjacent clamping sub-portions along the second direction. The connecting portion is configured to be spaced apart from the circuit board along the first direction.

[0023] In the above embodiment, by providing a plurality of clamping sub-parts, the clamping part can clamp and limit the circuit board at a plurality of points, thereby improving the assembly accuracy between the panel shell and the circuit board, which is conducive to accurately fitting the plug-in terminal to the avoidance opening. While maintaining a sufficient clamping connection range, the size of the structure of the clamping part itself can be reduced, which is conducive to reducing weight and production costs. At the same time, the connecting part connects two adjacent clamping sub-parts to reduce the possibility of misalignment between different clamping sub-parts, thereby maintaining the accuracy of the clamping part clamping and limiting the circuit board.

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

[0025] In the above embodiment, during the assembly process of the panel shell, the panel shell and the main shell can be clamped together while the circuit board can be clamped, so that the alignment and adaptation with the plug-in terminals can be completed during the assembly, so as to simplify the assembly process and improve the assembly efficiency. In addition, the plug-in terminals do not need to be fixed to the panel shell in advance, but can be directly integrated on the circuit board to save the wiring process, thereby reducing the assembly cost and simplifying the assembly process.

[0047] A mobile energy storage device usually has plug-in terminals electrically connected to an external structure. The plug-in terminals are exposed to the outside through openings on the device housing. During the device assembly process, the alignment of the plug-in terminals with the housing openings is involved. In the related art, either the plug-in terminals are first assembled on the housing and then connected to the circuit board, but the narrow space is not convenient for connecting the plug-in terminals to the circuit board, which results in a low overall assembly efficiency of the device; or the plug-in terminals are first connected to the circuit board and then the plug-in terminals are assembled with the housing, but the alignment accuracy requirement for the plug-in terminals and the housing openings is relatively high, also resulting in a low overall assembly efficiency of the device.

[0048] Embodiments of the present application provide a housing assembly and an energy storage power supply. The housing assembly is applied to the energy storage power supply. The energy storage power supply includes a circuit board. Plug-in terminals are provided on the circuit board. The housing assembly includes a main housing and a panel housing. The main housing is configured to fixedly accommodate the circuit board. And the main housing is provided with an assembly notch. The panel housing is provided with an avoidance opening and is formed with a clamping portion and a clamping connection portion. The clamping portion is configured to synchronously clamp the circuit board during the process of the panel housing being assembled into the assembly notch, so as to restrict the movement of the panel housing relative to the circuit board in a first direction. The clamping connection portion is configured to synchronously clamp to the edge of the assembly notch during the process of the panel housing being assembled into the assembly notch, so as to restrict the movement of the panel housing relative to the circuit board in a second direction. The first direction and the second direction form an included angle. The avoidance opening is configured to be adapted to the plug-in terminals after the panel housing is assembled to the main housing, so that the plug-in terminals are exposed to the outside.

[0049] During the process of the panel housing being assembled into the assembly notch, the clamping connection portion is clamped to the edge of the assembly notch, so that the panel housing is fixed to the main housing. The circuit board is fixed in the main housing. While the clamping connection portion clamps the edge of the assembly notch, the clamping portion can synchronously clamp the circuit board, so that the panel housing is fixed to the main housing and is synchronously fixed to the circuit board at the same time. And the clamping portion positions the panel housing relative to the circuit board in the first direction, and the clamping connection portion positions the panel housing relative to the circuit board in the second direction. Then, while the panel housing is fixed to the circuit board, the panel housing is synchronously positioned with the circuit board in a two-dimensional space, so that the plug-in terminals assembled on the circuit board are positioned with the avoidance openings formed on the panel housing in a two-dimensional space. Therefore, the plug-in terminals can be exposed to the outside through the avoidance openings for the energy storage power supply to be connected to external devices. And the positioning of the plug-in terminals and the avoidance openings is carried out synchronously with the assembly of the panel housing and the main housing. Therefore, while ensuring the alignment accuracy between the housing assembly and the plug-in terminals, the assembly efficiency is improved by eliminating additional positioning operations.

[0050] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0051] See Figure 1, an 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 is used for household power backup, power backup of production units, outdoor operations, outdoor entertainment, etc.

[0052] It can be understood that in some embodiments, the energy storage power supply 200 can be used independently and supply power to electrical equipment. In other embodiments, the energy storage power supply 200 can be used in coordination with other energy storage devices as a power supply system providing additional battery capacity.

[0053] See Figure 1 , Figure 2 and Figure 6 , in some embodiments, the energy storage power supply 200 includes a circuit board 201 and a housing assembly 100. The circuit board 201 is disposed within the housing assembly 100. The housing assembly 100 protects the circuit board 201.

[0054] It can be understood that in some embodiments, the circuit board 201 can be a BMS (Battery Management System) board or a PSDR (Power Supply Driver, inverter) board.

[0055] See Figure 1 and Figure 2 , in some embodiments, the energy storage power supply 200 further includes a plug-in terminal 202. The plug-in terminal 202 is integrated on the circuit board 201. The housing assembly 100 is provided with an avoidance opening 211. The plug-in terminal 202 is exposed to the outside through the avoidance opening 211. The energy storage power supply 200 is connected to an external device through the plug-in terminal 202.

[0056] It can be understood that in some embodiments, the plug-in terminal 202 can be various types of USB (Universal Serial Bus) interfaces, various types of audio interfaces, various types of fiber optic interfaces, etc.

[0057] See Figure 1 , Figure 3 and Figure 4 , in some embodiments, the housing assembly 100 includes a main housing 10 and a panel housing 20. The main housing 10 is configured to fixedly accommodate the circuit board 201. And the main housing 10 is provided with an assembly notch 11. The panel housing 20 is assembled to the assembly notch 11. The panel housing 20 is provided with an avoidance opening 211 for the plug-in terminal 202 to be exposed.

[0058] See Figure 1 , Figure 3 and Figure 4, in some embodiments, the circuit board 201 is fixedly connected to the main housing 10. The panel housing 20 is formed with a clamping portion 22 and a clamping connection portion 23. The clamping portion 22 is configured to clamp the circuit board 201 synchronously during the process of assembling the panel housing 20 into the assembly notch 11, so as to restrict the movement of the panel housing 20 relative to the circuit board 201 in the first direction. The clamping connection portion 23 is configured to be clamped to the edge of the assembly notch 11 synchronously during the process of assembling the panel housing 20 into the assembly notch 11, so as to restrict the movement of the panel housing 20 relative to the circuit board 201 in the second direction. An included angle is formed between the first direction and the second direction. The avoidance opening 211 is configured to be adapted to the plug-in terminal 202 after the panel housing 20 is assembled to the main housing 10, so that the plug-in terminal 202 is exposed to the outside. It can be understood that, in some embodiments, the first direction and the second direction are perpendicular to each other.

[0059] During the process of assembling the panel housing 20 into the assembly notch 11, the clamping connection portion 23 is clamped to the edge of the assembly notch 11, so that the panel housing 20 is fixed to the main housing 10. The circuit board 201 is fixed in the main housing 10, and while the clamping connection portion 23 clamps the edge of the assembly notch 11, the clamping portion 22 can clamp the circuit board 201 synchronously, so that when the panel housing 20 is fixed to the main housing 10, it is synchronously fixed to the circuit board 201.

[0060] The clamping portion 22 positions the panel housing 20 relative to the circuit board 201 in the first direction, and the clamping connection portion 23 positions the panel housing 20 relative to the circuit board 201 in the second direction. Then, while the panel housing 20 is fixed to the circuit board 201, the panel housing 20 is synchronously positioned relative to the circuit board 201 in a two-dimensional space, so that the plug-in terminal 202 assembled on the circuit board 201 and the avoidance opening 211 formed on the panel housing 20 are positioned in a two-dimensional space. Therefore, the plug-in terminal 202 can be exposed to the outside through the avoidance opening 211 for the energy storage power supply 200 to be connected to an external device.

[0061] The positioning of the plug-in terminal 202 and the avoidance opening 211 is carried out synchronously with the assembly of the panel housing 20 and the main housing 10. Therefore, while ensuring the alignment accuracy between the housing assembly 100 and the plug-in terminal 202, the assembly efficiency is improved by eliminating an additional positioning operation.

[0062] The housing assembly 100 can achieve alignment and adaptation with the plug-in terminal 202 during assembly, so that the plug-in terminal 202 does not need to be fixed to the panel housing 20 in advance, which is beneficial to directly integrating the plug-in terminal 202 on the circuit board 201 to eliminate the wiring process, thereby reducing the assembly cost and simplifying the assembly process.

[0063] See Figure 1, in some embodiments, it is defined that an included angle is formed between the third direction and the first direction and the second direction pairwise. The first direction is the direction parallel to the X shown in the figure, the second direction is the direction parallel to the Y shown in the figure, and the third direction is the direction parallel to the Z shown in the figure. For the convenience of referring to the figure, hereinafter, the first direction is represented by "First Direction X", the second direction is represented by "Second Direction Y", and the third direction is represented by "Third Direction Z". Optionally, in some embodiments, the First Direction X, the Second Direction Y, and the Third Direction Z are pairwise perpendicular to each other.

[0064] See Figures 1 to 4 , in some embodiments, when the panel shell 20 is assembled with the main housing 10, the panel shell 20 can first be aligned and fitted with one side edge of the assembly notch 11, and then flip with this side edge as a fulcrum. Along with the flipping process of the panel shell 20, the clamping portion 23 synchronously clamps the other side edges of the assembly notch 11 to realize the assembly of the panel shell 20 and the main housing 10. The axis of flipping of the panel shell 20 is parallel to the Second Direction Y, so as to facilitate the clamping portion 23 to accurately clamp the edge of the assembly notch 11 to limit the panel shell 20 in the Second Direction Y. And along with the flipping process of the panel shell 20, the clamping portion 22 synchronously clamps the circuit board 201 to be aligned and adapted to the circuit board 201.

[0065] In other embodiments, when the panel shell 20 is assembled with the main housing 10, the panel shell 20 can translate along the Third Direction Z. Along with the translation process of the panel shell 20 along the Third Direction Z, the clamping portion 23 synchronously clamps the edge of the assembly notch 11 to realize the assembly of the panel shell 20 and the main housing 10. And along with the translation process of the panel shell 20, the clamping portion 22 synchronously clamps the circuit board 201 to be aligned and adapted to the circuit board 201.

[0066] See Figure 4 , in some embodiments, the panel shell 20 includes a panel main body 21. The panel main body 21 is provided with an avoidance opening 211. The clamping portion 22 is connected to the panel main body 21. The clamping portion 23 is connected to the panel main body 21.

[0067] See Figure 2 and Figure 4 , in some embodiments, the minimum distance between the connection surface range of the clamping portion 22 on the panel main body 21 and the coverage range of the avoidance opening 211 on the panel main body 21 is less than or equal to the maximum distance within the connection surface range of the clamping portion 22 on the panel main body 21.

[0068] On the panel body 21, by restricting the positional relationship between the clamping portion 22 and the relief opening 211 on the panel body 21, the clamping portion 22 is brought closer to the relief opening 211 and the insertion terminal 202, so as to reduce the influence of the deformation of the circuit board 201 itself on the alignment accuracy of the insertion terminal 202 and the relief opening 211, which is beneficial to improving the alignment and adaptation accuracy between the housing assembly 100 and the insertion terminal 202. Specifically, it is not convenient to add another clamping portion 22 arranged along the maximum width direction of the connection surface between a certain clamping portion 22 and the relief opening 211, making this clamping portion 22 relatively close to the relief opening 211; otherwise, if it is easy to set another clamping portion 22 between this clamping portion 22 and the relief opening 211, then the newly added clamping portion 22 that should be added is closer to the relief opening 211 and can provide a better limiting effect.

[0069] It can be understood that in some embodiments, the panel body 21 of the panel housing 20 is provided with a plurality of relief openings 211, and the clamping portion 22 and the closest relief opening 211 meet the above distance requirements. In some embodiments, there are a plurality of clamping portions 22, and each clamping portion 22 and the closest relief opening 211 can meet the above distance requirements, or some clamping portions 22 and their respective closest relief openings 211 can meet the above distance requirements.

[0070] See Figure 2 、 Figure 4 and Figure 6 In some embodiments, the clamping portion 22 includes a clamping sub - portion 221 and a connecting portion 222. There are a plurality of clamping sub - portions 221 which are spaced apart along the second direction Y on the panel body 21. The connecting portion 222 connects two adjacent clamping sub - portions 221 along the second direction Y. The connecting portion 222 is configured to be spaced apart from the circuit board 201 along the first direction X.

[0071] By providing a plurality of clamping sub - portions 221, the clamping portion 22 clamps and limits the circuit board 201 through a plurality of points, thereby improving the assembly accuracy between the panel housing 20 and the circuit board 201, which is beneficial to accurately adapting the insertion terminal 202 and the relief opening 211. And while maintaining a sufficient clamping and connecting range, the structural size of the clamping portion 22 itself can be reduced, which is beneficial to reducing weight and production costs. At the same time, the connecting portion 222 connects two adjacent clamping sub - portions 221 to reduce the possibility of misalignment between different clamping sub - portions 221, thereby maintaining the accuracy of the clamping and limiting of the circuit board 201 by the clamping portion 22.

[0072] See Figure 2 、 Figure 4 and Figure 6 In some embodiments, the clamping portion 22 is provided with a clamping groove 223. The clamping groove 223 is configured to synchronously supply the circuit board 201 for insertion during the process of assembling the panel housing 20 into the assembly notch 11.

[0073] The circuit board 201 is inserted into the clamping groove 223 so that the clamping portion 22 clamps the circuit board 201. The clamping portion 22 clamps the circuit board 201 in the first direction X to restrict the relative position between the panel housing 20 and the circuit board 201 in the first direction X.

[0074] See Figure 2 、 Figure 5 and Figure 6 In some embodiments, the clamping portion 22 is provided with a guiding surface 224. The guiding surface 224 is connected to the groove wall of the clamping groove 223. The guiding surface 224 is configured to be located on at least one side of the clamping portion 22 facing the circuit board 201 in the first direction X. And the guiding surface 224 is configured to gradually approach the circuit board 201 along the direction in which the circuit board 201 is inserted into the clamping groove 223.

[0075] By providing the guiding surface 224, the clamping portion 22 can guide the circuit board 201 away from the clamping groove 223 in the first direction X to be close to the clamping groove 223, so as to reduce the alignment action between the clamping portion 22 and the circuit board 201 in the first direction X, which is beneficial to the simultaneous clamping of the circuit board 201 by the clamping portion 22 while the engaging portion 23 engages with the assembly notch 11, thereby improving the assembly efficiency.

[0076] It can be understood that in some embodiments, the guiding surface 224 is a flat surface. In other embodiments, the guiding surface 224 can be an arc surface.

[0077] See Figures 2 to 4 In some embodiments, the engaging portion 23 is configured to be movable relative to the edge of the assembly notch 11 in the first direction X. It can be understood that in some embodiments, the engaging portion 23 is engaged with the edge of the assembly notch 11 in the third direction Z to fix the panel housing 20 and the main housing 10 in the third direction Z. For example, one side of the engaging portion 23 in the second direction Y has a protrusion and is engaged with the main housing 10 in the second direction Y and the third direction Z.

[0078] The main housing 10 fixes the circuit board 201. By adjusting the position of the engaging portion 23 relative to the edge of the assembly notch 11 in the first direction X, the clamping portion 22 can move relative to the circuit board 201 in the first direction X, which is beneficial to accurately clamping the circuit board 201 by the clamping portion 22 in the first direction X, so that the avoidance opening 211 and the insertion terminal 202 are accurately aligned and adapted in the first direction X. Optionally, by allowing the engaging portion 23 to move relative to the edge of the assembly notch 11 in the first direction X, the guiding surface 224 can adjust the position of the panel housing 20 relative to the circuit board 201 in the first direction X with the circuit board 201 as a support.

[0079] See Figure 2 、 Figure 4 and Figure 6, in some embodiments, the panel housing 20 is further provided with a limiting portion 24. The limiting portion 24 is at least partially disposed in the clamping groove 223. The limiting portion 24 is configured to stop the circuit board 201 along the direction in which the circuit board 201 is inserted into the clamping groove 223, so that the insertion terminal 202 and the edge of the avoidance opening 211 are spaced apart along the direction in which the circuit board 201 is inserted into the clamping groove 223. It can be understood that in some embodiments, the limiting portion 24 can extend along the second direction Y to a plurality of clamping sub-portions 221 within the same clamping portion 22.

[0080] As the circuit board 201 is inserted into the clamping groove 223, the insertion terminal 202 gradually approaches the avoidance opening 211. By providing the limiting portion 24, the insertion depth of the circuit board 201 in the clamping groove 223 is restricted, so that the insertion terminal 202 is separated from the panel housing 20. If the energy storage power supply 200 encounters scenarios such as dropping or collision, the panel housing 20 directly impacts or applies a force to the circuit board 201 rather than the insertion terminal 202, which is beneficial to avoiding the separation of the insertion terminal 202 from the circuit board 201 due to impact, thereby protecting the safety of the insertion terminal 202.

[0081] See Figure 1 and Figure 2 , in some embodiments, the limiting portion 24 is configured to be spaced apart from the circuit board 201 along the direction in which the circuit board 201 is inserted into the clamping groove 223. And along the direction in which the circuit board 201 is inserted into the clamping groove 223, the limiting portion 24 is configured to have a distance from the circuit board 201 greater than the distance between the edge of the avoidance opening 211 and the insertion terminal 202.

[0082] Along the direction in which the circuit board 201 is inserted into the clamping groove 223, the limiting portion 24 does not directly abut against the circuit board 201, so as to provide redundancy between the assembly of the panel housing 20 and the main housing 10 and the assembly of the panel housing 20 and the circuit board 201, which is beneficial to reducing the production operation requirements and thus reducing the production cost. At the same time, along the direction in which the circuit board 201 is inserted into the clamping groove 223, by controlling the distance between the insertion terminal 202 and the avoidance opening 211 to be greater than the distance between the circuit board 201 and the limiting portion 24, it is ensured that the circuit board 201 contacts the panel housing 20 prior to the insertion terminal 202, thereby protecting the safety of the insertion terminal 202.

[0083] See Figure 2 , Figure 5 and Figure 6 , in some embodiments, the limiting portion 24 and / or the clamping portion 22 are provided with a limiting surface 241. The limiting surface 241 faces the second direction Y. The circuit board 201 is provided with a mating surface 2011. The mating surface 2011 faces the second direction Y. The limiting surface 241 is configured to abut against the mating surface 2011 of the circuit board 201 along the second direction Y.

[0084] The limiting surface 241 abuts against the mating surface 2011 in the second direction Y. On the one hand, on the basis of the positioning of the clamping portion 23 in the second direction Y, the positioning accuracy of the panel housing 20 relative to the circuit board 201 is further improved, which is beneficial to improving the alignment and adaptation accuracy between the insertion terminal 202 and the avoidance opening 211. On the other hand, when the limiting effect of the clamping portion 23 on the panel housing 20 in the second direction Y fails, it can assist in limiting the panel housing 20, thereby maintaining the adaptation between the insertion terminal 202 and the avoidance opening 211.

[0085] See Figure 2 、 Figure 4 and Figure 6 , in some embodiments, the limiting portion 24 is configured to be elastically deformed under the extrusion of the circuit board 201. When the energy storage power supply 200 encounters scenarios such as dropping or collision, or when the circuit board 201 is inserted into the clamping groove 223, the limiting portion 24 can absorb the impact between the panel housing 20 and the circuit board 201 through elastic deformation, provide buffering for the movement or movement trend of the circuit board 201 along the direction of inserting into the clamping groove 223, thereby protecting the safety between the panel housing 20 and the circuit board 201.

[0086] As an exemplary example, the limiting portion 24 can be various types of rubber, fabric, metal elastic sheets, etc.

[0087] See Figure 2 and Figure 4 , in some embodiments, the limiting portion 24 and the clamping portion 22 are of an integrally formed structure. See Figure 4 and Figure 5 , in some embodiments, the limiting portion 24 and the clamping portion 22 are of a split structure.

[0088] See Figure 5 and Figure 6 , in some embodiments, the clamping portion 22 has a first buffer layer 225 and a second buffer layer 226. The first buffer layer 225 and the second buffer layer 226 are relatively arranged along the first direction X and are configured to respectively abut against the circuit board 201. Both the first buffer layer 225 and the second buffer layer 226 are configured to be elastically deformed under the extrusion of the circuit board 201. When the circuit board 201 is not inserted between the first buffer layer 225 and the second buffer layer 226, in the first direction X, the distance between the first buffer layer 225 and the second buffer layer 226 is configured to be less than or equal to the thickness of the circuit board 201.

[0089] The clamping portion 22 clamps and positions the circuit board 201 in the first direction X. By providing the first buffer layer 225 and the second buffer layer 226, on the one hand, the production error between the thickness of the clamping portion 22 and the circuit board 201 in the first direction X can be eliminated through elastic deformation, so as to avoid the generation of a gap between the clamping portion 22 and the circuit board 201 in the first direction X, which reduces the alignment accuracy between the insertion terminal 202 and the avoidance opening 211, and to avoid the generation of a negative gap between the clamping portion 22 and the circuit board 201, which may prevent the clamping of the circuit board 201 or damage the circuit board 201. This is conducive to reducing the production operation requirements and production costs. On the other hand, the impact between the clamping portion 22 and the circuit board 201 can be absorbed through elastic deformation, providing a buffer for the moving trend of the circuit board 201 in the first direction X, thereby protecting the safety between the clamping portion 22 and the circuit board 201.

[0090] As an exemplary example, the first buffer layer 225 and the second buffer layer 226 can be various types of rubber, fabric, metal shrapnel, etc.

[0091] It can be understood that in some embodiments, each clamping sub-portion 221 is provided with the first buffer layer 225 and the second buffer layer 226. In some embodiments, a clamping groove 223 is formed between the first buffer layer 225 and the second buffer layer 226. In some embodiments, the guiding surface 224 is configured to be located on the side of the first buffer layer 225 and / or the second buffer layer 226 facing the circuit board 201 in the first direction X.

[0092] See Figure 1 、 Figure 3 and Figure 4 In some embodiments, as shown in

[0093] See Figures 1 to 4 In some embodiments, the assembly process of the energy storage power supply 200 is as follows:

[0094] The circuit board 201 is fixedly connected to the main housing 10. The panel housing 20 is gradually moved closer to the assembly notch 11 in the third direction Z until the clamping portion 23 is clamped to the edge of the assembly notch 11. During this process, the clamping portion 22 synchronously clamps the circuit board 201, thereby completing the assembly of the energy storage power supply 200.

[0095] In addition, those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as appropriate changes and variations made to the above embodiments fall within the scope of the spirit of the present application, they all fall within the scope of disclosure of the present application.
