Description

Technical Field

[0001] This invention belongs to the field of new energy storage and application technology, and specifically relates to an expandable portable multi-functional energy storage and power supply device. Background Technology

[0002] With the advancement of technology, electronic products are being used more and more frequently in daily life; at the same time, more and more traditional products, such as bicycles, cars, and tea stoves, are also adopting electricity as a new power source, making the use of energy storage power supply equipment more and more common.

[0003] Most existing energy storage power supply equipment exists in the form of charging cabinets, which generally only include battery packs, BMS controllers, inverter modules, etc., using mains power as the power source to provide simple power supply functions.

[0004] For example, the existing patent with application number CN201920628685.2 discloses an outdoor electric vehicle charging cabinet for charging electric vehicle batteries. The cabinet contains multiple charging compartments for inserting electric vehicle lithium batteries, supported by brackets. Insulating guides in multiple directions are provided along the battery insertion path within each compartment to limit battery insertion. A limit sensor button is located at the end of the battery insertion path. This design allows for convenient charging for electric vehicle users in outdoor environments. However, the charging cabinet product disclosed in the aforementioned patent has a single form, cannot be expanded, and has a limited scope of application.

[0005] Based on this, expandable smart charging cabinets have emerged in the market. For example, the existing patent with application number CN202121401771.3 discloses a combined expandable multimedia smart charging cabinet, including an expansion cabinet and a control cabinet. The front of the control cabinet is equipped with a touch screen and a QR code scanning module. The control cabinet contains a control host, a voice module, a relay, and a power supply module. The side of the expansion cabinet has a through hole for wiring and a waterproof cover. The expansion cabinet has multiple charging compartments. The top surface of each charging compartment is equipped with a plunger-type micro switch, and the inner side of each charging compartment is equipped with an electromagnetic lock. The front of the expansion cabinet is fitted with a cabinet door via a hinge, and the rear of the cabinet door is fitted with a latch box. The vertical edges of the expansion cabinet and the control cabinet are provided with snap-fit ​​strips and snap-fit ​​slots. The expansion cabinet and the control cabinet can be quickly assembled into a whole of different lengths using snap-fit ​​strips, snap-fit ​​slots, and connecting bolts, thus realizing the expansion of the smart charging cabinet. Although the smart charging cabinet disclosed in this patent can expand the cabinet, it only expands the number of charging compartments and cannot expand the function of the cabinet. It can only charge modular batteries, which has the disadvantage of single product function. It is highly homogeneous with existing products on the market and cannot meet the multi-scenario application needs of users. Summary of the Invention

[0006] To address the aforementioned issues, the primary objective of this invention is to provide an expandable, portable, multifunctional energy storage and power supply device. This device is expandable and can integrate different functional modules through a unified standard interface, greatly broadening the applicability of energy storage products, expanding application scenarios, and making energy storage and power generation devices more portable. Another objective of this invention is to provide an expandable, portable, multifunctional energy storage and power supply device that can be used as a power supply base, allowing for unlimited expansion of applications.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: This invention provides an expandable, portable, multi-functional energy storage and power supply device, comprising one or more energy storage and power supply units. Adjacent energy storage and power supply units are stacked vertically and electrically connected to each other. Each energy storage and power supply unit includes a unit body, and the unit body includes one or more module expansion compartments. Functional modules are disposed within each module expansion compartment. A unit control board is disposed on the unit body at a position corresponding to the module expansion compartment. The unit control board is provided with standard interface terminals. Each functional module contains a module control board, and the module control board is provided with a standard interface adapted to the standard interface terminals. The standard interface terminals are electrically connected to the standard interface. In this application, functional modules such as battery modules, adapter modules, and inverter modules can be installed in the module expansion compartments. The module expansion compartments are provided with unified standard interface terminals. Only standard interfaces adapted to the standard interface terminals need to be provided on the control boards of each functional module. Electrical connection between each functional module and the unit body is achieved through the plug-in connection of the standard interfaces to the standard interface terminals. This gives the device a multi-functional effect, eliminating the need for external mains power, inverters, or other equipment, making it more portable. Secondly, the energy storage power supply unit of this application can be configured with multiple layers, and the series and parallel connections between the energy storage power supply units of each layer are realized through stacking, which has scalability and the number of energy storage power supply units can be set according to specific application scenarios.

[0008] Furthermore, the functional modules include a battery module, an adapter module, and an inverter module. In this application, the battery module can supply power to the energy storage power supply device, the adapter module can adapt to various different sockets, and the inverter module can convert AC power for use with different devices to be powered.

[0009] Furthermore, the standard interface terminal includes a Type-C terminal, and the standard interface includes a Type-C interface. The Type-C connection is used to realize the electrical connection between the energy storage power supply unit and the functional module, which can not only power the functional module, but also transmit data.

[0010] Furthermore, the unit control board is provided with a first anti-mistake terminal group and a second anti-mistake terminal group, which are symmetrically arranged on the left and right sides of the standard interface terminal, respectively. The module control board is provided with a first anti-mistake socket group and a second anti-mistake socket group corresponding to the positions of the first and second anti-mistake terminal groups, which are symmetrically arranged on the left and right sides of the standard interface, respectively. In this application, anti-mistake socket groups adapted to the anti-mistake terminal groups are provided on the functional modules to realize the electrical connection between the functional modules and the unit body. By setting the anti-mistake terminal groups and anti-mistake socket groups as two symmetrical structures, normal power supply can be achieved regardless of positive or negative connection, thus providing an anti-mistake effect.

[0011] Furthermore, both the first and second anti-mistake terminal groups include an even number of anti-mistake connecting pieces, and both the first and second anti-mistake socket groups include an even number of anti-mistake sockets. Adjacent anti-mistake connecting pieces form a set of positive and negative connections, and adjacent anti-mistake sockets form a set of positive and negative connections. Users can achieve normal positive and negative electrical connections of the module when inserting it in either direction, thus providing a positive and negative anti-mistake effect.

[0012] Furthermore, the energy storage power supply unit also includes a front locking shell, which is connected to the front end of the module expansion compartment. The front end of the functional module is provided with a locking part, which is movably engaged with the front locking shell. In this application, the movable engagement between the locking part and the front locking shell not only secures the functional module to the module expansion compartment but also allows for the disassembly of the functional module, facilitating assembly.

[0013] Furthermore, the front locking shell is provided with an opening communicating with the module expansion compartment. The front locking shell has a slot on the side wall of the opening. The locking part includes a fixed body, a movable buckle, a return spring, and a toggle member. The fixed body has a movable groove, and both the movable buckle and the return spring are disposed within the movable groove. The front end of the movable buckle penetrates the side wall of the movable groove and is movably engaged within it. One end of the return spring abuts against the end of the movable buckle, and the other end abuts against the side wall of the movable groove away from the slot. The toggle member is rotatably connected to the fixed body, and can rotate to move the movable buckle towards the return spring within the movable groove, causing the front end of the movable buckle to retract into the movable groove. In this application, when the functional module is installed in the module expansion compartment, the movable buckle engages in the slot, achieving a locking mechanism between the two. When it is necessary to disassemble or assemble a functional module, simply move the lever to rotate it on the fixed body, forcing the movable latch to move toward the return spring. The front end of the movable latch retracts into the movable slot, and the movable latch will not engage with the slot, thus enabling the disassembly or assembly of the functional module. When the disassembly or assembly of the functional module is complete, release the lever, and the movable latch will return to its original position under the action of the return spring. The front end of the movable latch can then engage with the slot to achieve locking.

[0014] Furthermore, a pivot is provided on the outer surface of the fixed body, and the actuating component is rotatably connected to the fixed body via the pivot. A through hole is also provided on the outer surface of the fixed body, and a first actuating baffle is provided on the inner side of the actuating component. A second actuating baffle is provided on the outer side of the movable buckle. The first actuating baffle passes through the through hole and abuts against the second actuating baffle. When the actuating component is moved, the first actuating baffle pushes the second actuating baffle to move, thereby moving the movable buckle within the movable groove.

[0015] Furthermore, the outer surface of the fixing body is also provided with an outwardly protruding limiting protrusion, and the actuating component is provided with an actuating plate connected to the first actuating baffle. The actuating plate is provided with a limiting groove, and the front end of the limiting protrusion is limited within the limiting groove. During normal use, the actuating plate can be limited and fixed.

[0016] Furthermore, the energy storage power supply unit also includes a conductive pillar assembly, which is electrically connected to the unit control board, and its upper and lower ends extend outside the energy storage power supply unit. In this application, the stacked energy storage power supply units are electrically connected through the conductive pillar assembly, thereby achieving power supply connection for all energy storage power supply units.

[0017] Furthermore, the conductive column assembly includes a conductive column body, an upper movable buckle, an upper ejection spring, and a lower adjusting spring. The energy storage power supply unit also has a vertically penetrating columnar groove. A groove is provided on the outer side of the top sidewall of the columnar groove, and a protrusion adapted to the groove is provided on the outer side of the bottom sidewall of the columnar groove. The upper movable buckle is movably disposed within the groove. Both the upper movable buckle and the protrusion have through holes communicating with the columnar groove. The conductive column body is disposed within the columnar groove, and the upper and lower... Both ends pass through the through holes of the protrusion and the upper movable buckle, respectively. The middle part of the conductive post body protrudes outward to form a wiring connection post. The upper ejection spring is located on the upper part of the conductive post body, and the upper end of the upper ejection spring abuts against the bottom of the upper movable buckle. The lower end of the upper ejection spring abuts against the upper top surface of the wiring connection post. The lower adjustment spring is sleeved on the lower part of the conductive post body, and the upper end of the lower adjustment spring abuts against the lower bottom surface of the wiring connection post. The lower end of the lower adjustment spring abuts against the lower bottom surface of the columnar groove. In this application, when the energy storage power supply units are stacked, the protrusion at the bottom of the upper energy storage power supply unit aligns with the groove at the top of the lower energy storage power supply unit. The upper energy storage power supply unit layer presses down under its own weight, and the protrusion of the lower conductive column assembly presses the upper movable buckle of the lower conductive column assembly downward within its groove, causing the top of the conductive column body of the lower energy storage power supply unit to be exposed and able to abut against the bottom of the conductive column body of the upper energy storage power supply unit, achieving tight contact and ensuring the stability of the connection between the upper and lower energy storage power supply units. At the same time, when the upper and lower conductive column bodies abut against each other, both the upper and lower conductive column bodies will undergo relative displacement within the columnar groove due to pressure. At this time, the lower adjusting spring can adjust the position of the conductive column body through its own elasticity to avoid excessive displacement. In addition, the upper ejector spring is compressed during stacking, and when the upper energy storage power supply unit is removed, the upper movable buckle of the lower part can also be reset by the elasticity of the upper ejector spring.

[0018] Furthermore, the conductive post assembly also includes a limiting buckle. A limiting slot is provided on the wiring connection post, and a limiting mounting groove is provided on the side wall of the columnar groove. Both sides of the limiting buckle are fixed within the limiting mounting groove, and the middle of the limiting buckle is engaged within the limiting slot and can move up and down within the limiting slot. When the conductive post body moves up and down within a certain range, the limiting buckle can remain engaged in the limiting slot, thus limiting the up and down movement of the conductive post body and preventing it from coming out of the columnar groove.

[0019] Furthermore, the energy storage power supply unit also includes a rear shell, and four sets of conductive pillar assemblies are provided. Both the rear shell and the front locking shell have two parallel columnar slots, with the two columnar slots on the front locking shell located directly in front of the two columnar slots on the rear shell. The four sets of conductive pillar assemblies are respectively disposed within the four columnar slots. Two first connecting flexible wires are provided within the unit body, and two second connecting flexible wires are also provided within the rear shell. The front end of the first connecting flexible wire is electrically connected to the conductive pillar body within the front locking shell, and the rear end of the first connecting flexible wire is connected to a first electrical connection block, which is electrically connected to the unit control board. The rear end of the second connecting flexible wire is electrically connected to the conductive pillar body within the rear shell, and the front end of the second connecting flexible wire is connected to a second electrical connection block, which is electrically connected to the unit control board. In this application, four sets of conductive pillar assemblies are used to achieve cross-electrical connections between the various module expansion compartments within the energy storage power supply unit, as well as electrical connections between adjacent energy storage power supply units. Secondly, the energy storage power supply unit of this application can also be used as a power supply base outdoors. It is only necessary to set four connection ends with conductive column components at the bottom of products such as electric tea stoves, electric ovens, wireless charging stations, induction cookers, outdoor fans, outdoor refrigerators, outdoor coffee machines, outdoor lighting, electric bicycles, drones, and power tools to achieve electrical connection with this energy storage power supply unit, which can effectively expand the application scenarios of the products.

[0020] Furthermore, a first locking ring is fitted around the rear end of the first connecting wire, and a first locking screw is threaded onto the first locking ring. Both the first electrical connection block and the rear end of the first connecting wire are located within the first locking ring and are locked in place by the first locking screw. Similarly, a second locking ring is fitted around the rear end of the second connecting wire, and a second locking screw is threaded onto the second locking ring. Both the second electrical connection block and the rear end of the second connecting wire are located within the second locking ring and are locked in place by the second locking screw. In this application, both the first and second connecting wires are made of flexible copper wire, allowing for movement. One end of the copper wire is fixed by a locking screw, while the conductive post body connected to the other end can move up and down using the bending characteristics of the flexible copper wire, allowing for a certain range of motion and facilitating close contact between the upper and lower conductive post bodies.

[0021] Furthermore, a cooling fan is also provided at the rear of the module expansion compartment. The cooling fan is electrically connected to the unit control board. The cooling fan is located inside the rear shell, and the rear shell is also provided with ventilation holes.

[0022] Furthermore, a power generation control module is also provided on the top of the energy storage power supply unit. The power generation control module includes a housing and an electrical control assembly. The electrical control assembly is housed within the housing and includes a power generation control board, electrical connection pieces, and power generation connection posts. Four power generation connection posts are provided. The housing has four connection holes corresponding to the positions of the conductive post assemblies of the energy storage power supply unit. The four power generation connection posts are respectively installed in the four connection holes and electrically connected to the conductive post assemblies. Two electrical connection pieces are provided, and the four power generation connection posts are connected in a cross shape via the two electrical connection pieces. The electrical connection pieces are also electrically connected to the power generation control board. The power generation control board also has a standard power interface with one end exposed. In this application, the power generation control module can connect to an external wind power generation device or solar power generation device through the standard power interface to achieve power generation control. Then, it is electrically connected to the energy storage power supply unit through the four power generation connection posts to store electrical energy in the battery module. It should be noted that the control principle of the power generation control module in this application belongs to conventional wind power generation and solar power generation control technology, which is prior art. The specific implementation method does not need to be disclosed in this application.

[0023] Furthermore, the housing includes an upper shell and a lower shell, and the power generation connection post includes a threaded connection post. The threaded connection post can realize the electrical connection between the power generation control module and the energy storage power supply unit, and also realize the fixation between the upper shell and the lower shell.

[0024] The advantage of this invention is that, compared to existing technologies: 1. By setting standardized interfaces, the functionality of the product can be expanded in a modular way, increasing the product's variability and differentiation, and expanding the product's application scenarios; 2. Each functional module is installed and disassembled using a snap-fit ​​structure, which is simple and easy to assemble and disassemble; 3. The energy storage and power supply units of the product are connected in series and parallel using conductive copper pillars, which simplifies the traditional terminal wiring method and facilitates the stacking and expansion of energy storage and power supply units; 4. The functional modules and energy storage power supply units adopt a reverse connection design to prevent incorrect connection, making electrical connection more convenient.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0054] To achieve the above objectives, the technical solution of this embodiment is as follows: See Figure 1-22As shown, this embodiment provides an expandable portable multi-functional energy storage power supply device, including one or more energy storage power supply units 100. Adjacent energy storage power supply units 100 are stacked vertically and electrically connected to each other. Each energy storage power supply unit includes a unit body 1, and the unit body 1 includes one or more module expansion compartments 11. The module expansion compartment 11 contains a battery module 2, an adapter module 3, and an inverter module 4. The unit body 1 has a unit control board 12 at a position corresponding to the module expansion compartment 11. The unit control board 12 has a Type-C terminal 13. The battery module 2, adapter module 3, and inverter module 4 each have a module backplate 5. The module control board is located inside the module backplate 5. The module backplate 5 has a Type-C interface 51 adapted to the Type-C terminal 13. The Type-C interface 51 is connected to the module control board, and the Type-C terminal 13 is electrically connected to the Type-C interface 51. In this application, the module expansion compartment 11 can accommodate functional modules such as battery module 2, adapter module 3, and inverter module 4. Battery module 2 can power the energy storage power supply device, adapter module 3 can adapt to various different sockets, and inverter module 4 can convert AC power for use with different devices. The module expansion compartment 11 is equipped with a unified Type-C terminal 13. Only a Type-C interface 51 needs to be provided on the control board of each functional module. The Type-C terminal 13 and Type-C interface 51 are used to connect the functional modules to the unit body 1, enabling power supply and data transmission for each module. This gives the device a multi-functional effect, eliminating the need for external AC power or inverter equipment, making it more portable. Furthermore, the energy storage power supply unit 100 of this application can be multi-layered, with series and parallel connections between the layers of energy storage power supply units 100 achieved through stacking. This provides expandability, allowing the number of energy storage power supply units 100 to be set according to specific application scenarios.

[0055] See Figure 3 , 6 The unit control board 12 has two anti-misalignment connectors 14 on the left and right sides of the Type-C terminal 13, respectively. The two left anti-misalignment connectors 14 are symmetrical with the two right anti-misalignment connectors 14, forming a positive and negative connection. The module backplate 5 has two anti-misalignment sockets 52 on the left and right sides of the Type-C interface 51, respectively. The anti-misalignment sockets 52 are connected to the module control board, with the two left anti-misalignment sockets 52 symmetrical with the two right anti-misalignment sockets 52, forming a positive and negative connection. Users can achieve normal positive and negative electrical connection of the module regardless of whether it is plugged in correctly or incorrectly, providing a positive and negative misalignment prevention effect.

[0056] See Figure 1-6 The energy storage power supply unit 100 also includes a front locking shell 6, which is connected to the front end of the module expansion compartment 11. Locking parts 7 are provided at the front ends of the battery module 2, adapter module 3, and inverter module 4, and these locking parts are movably engaged with the front locking shell 6. In this application, the movable engagement between the locking parts 7 and the front locking shell 6 not only secures the functional modules to the module expansion compartment 11 but also allows for the disassembly of each functional module, facilitating assembly.

[0057] See Figure 1-6 9, 10. The front locking shell 6 is provided with an opening 61 that communicates with the module expansion compartment 11. The front locking shell 6 is provided with a slot 62 on the side wall of the opening 61. The locking part 7 includes a fixed body 71, a movable buckle 72, a return spring 73, and a toggle member 74. The fixed body 71 is provided with a movable groove 711. The movable buckle 72 and the return spring 73 are both provided in the movable groove 711. The front end of the movable buckle 72 passes through the side wall of the movable groove 711 and is movably engaged in the slot 62. One end of the return spring 73 abuts against the end of the movable buckle 72, and the other end abuts against the side wall of the movable groove 711 away from the slot 62. The toggle member 74 is rotatably connected to the fixed body 71, and the toggle member 74 can rotate to drive the movable buckle 72 to move toward the return spring 73 in the movable groove 711, so that the front end of the movable buckle 72 retracts into the movable groove 711. In this application, when the functional module is installed in the module expansion compartment 11, the movable latch 72 engages with the slot 62, achieving a locking between the two. When it is necessary to disassemble or assemble the functional module, simply move the actuating element 74, causing it to rotate on the fixed body 71, forcing the movable latch to move towards the return spring 73. The front end of the movable latch 72 retracts into the movable groove 711, and the movable latch 72 will not engage with the slot 62, thus enabling the disassembly or assembly of the functional module. When the disassembly or assembly of the functional module is completed, release the actuating element 74, and the movable latch 72 will reset under the action of the return spring 73, allowing the front end of the movable latch 72 to engage with the slot 62, achieving a locking effect.

[0058] Furthermore, a pivot 75 is provided on the outer surface of the fixed body 71, and the actuating member 74 is rotatably connected to the fixed body 71 via the pivot 75. A through hole 712 is also provided on the outer surface of the fixed body 71. A first actuating baffle 741 is connected to the inner side of the actuating member 74, and a second actuating baffle 721 is connected to the outer side of the movable latch 72. The first actuating baffle 741 passes through the through hole 712 and abuts against the second actuating baffle 721. When the actuating member 74 is actuated, the first actuating baffle 741 pushes the second actuating baffle 721 to move, thereby moving the movable latch 72 within the movable groove 711.

[0059] See Figure 16The outer side of the fixed body 71 is also connected to an outwardly protruding limiting protrusion 76. The actuating member 74 is provided with an actuating piece 742 connected to the first actuating baffle 741. The actuating piece 742 is provided with a limiting groove 743, and the front end of the limiting protrusion 76 is limited within the limiting groove 743. During normal use, the actuating piece 742 can be limited and fixed.

[0060] See Figure 1-8 The energy storage power supply unit 100 also includes a conductive column assembly 8, which is electrically connected to the unit control board 12, and extends to the outside of the energy storage power supply unit 100 at both ends. In this application, the energy storage power supply units 100 stacked vertically are electrically connected through the conductive column assembly 8, thereby achieving power supply connection for all energy storage power supply units 100.

[0061] See Figure 6 , 813. The conductive column assembly 8 includes a conductive column body 81, an upper movable buckle 82, an upper ejection spring 83, and a lower adjusting spring 84. The energy storage and power supply unit 100 also has a vertically penetrating columnar groove 9. A groove 91 is provided on the outer side of the top sidewall of the columnar groove 9, and a protrusion 92 adapted to the groove 91 is provided on the outer side of the bottom sidewall of the columnar groove 9. The upper movable buckle 82 is movably disposed within the groove 91. Both the upper movable buckle 82 and the protrusion 92 have through holes 93 communicating with the columnar groove 9. The conductive column body 81 is disposed within the columnar groove 9, and the upper and lower ends of the conductive column body 81 are... Do not penetrate into the through hole 93 of the protrusion 92 and the upper movable buckle 82. The middle part of the conductive post body 81 protrudes outward to form a wiring connection post 85. The upper ejector spring 83 is sleeved on the upper part of the conductive post body 81, and the upper end of the upper ejector spring 83 abuts against the bottom of the upper movable buckle 82. The lower end of the upper ejector spring abuts against the upper top surface of the wiring connection post 85. The lower adjusting spring 84 is sleeved on the lower part of the conductive post body 81, and the upper end of the lower adjusting spring 84 abuts against the lower bottom surface of the wiring connection post 85. The lower end of the lower adjusting spring 84 abuts against the lower bottom surface of the columnar groove 9. In this application, when the energy storage power supply units 100 are stacked, the protrusion 92 at the bottom of the upper energy storage power supply unit 100 is in contact with the groove 91 at the top of the lower energy storage power supply unit 100. The upper energy storage power supply unit 100 is pressed down by its own weight, and the protrusion 92 of the lower conductive post assembly 8 presses the upper movable buckle 82 of the lower conductive post assembly 8 to move down in its groove 91, so that the top of the conductive post body 81 of the lower energy storage power supply unit 100 is exposed and can abut against the bottom of the conductive post body 81 of the upper energy storage power supply unit 100, so as to achieve close contact and ensure the stability of the connection between the upper and lower energy storage power supply units 100. Meanwhile, when the upper conductive column body 81 and the lower conductive column body 81 abut against each other, the upper and lower conductive column bodies 81 will both be displaced relative to each other in the columnar groove 9 due to pressure. At this time, the lower adjusting spring 84 can adjust the position of the conductive column body 81 by its own elastic force to avoid excessive displacement. In addition, the upper ejector spring will be compressed when stacked. When the upper energy storage power supply unit 100 is removed, the lower upper movable buckle 82 can also be reset by the elastic force of the upper ejector spring.

[0062] Furthermore, the conductive post assembly 8 also includes a limiting buckle 86, a limiting slot 851 is provided on the wiring connection post 85, and a limiting mounting slot 94 is provided on the side wall of the columnar groove 9. The two sides of the limiting buckle 86 are fixed in the limiting mounting slot 94, and the middle part of the limiting buckle 86 is engaged in the limiting slot 851 and can move up and down within the limiting slot 851. When the conductive post body 81 moves up and down within a certain range, the limiting buckle 86 can remain engaged in the limiting slot 851, thereby limiting the up and down movement of the conductive post body 81 and preventing the conductive post body 81 from coming out of the columnar groove 9.

[0063] Furthermore, the energy storage power supply unit 100 also includes a rear shell 10, and four sets of conductive column assemblies 8 are provided. The rear shell 10 and the front locking shell 6 are each provided with two parallel columnar grooves 9, and the two columnar grooves 9 on the front locking shell 6 are located directly in front of the two columnar grooves 9 on the rear shell 10.

The rear end of the second soft copper wire 30 is electrically connected to the conductive column body 81 in the rear shell 10, and the front end of the second soft copper wire 30 is connected to a second electrical connection block 301. The second electrical connection block 301 is electrically connected to the unit control board 12. In this application, four sets of conductive pillar assemblies 8 are used to achieve cross-electrical connections between the various module expansion compartments 11 within the energy storage power supply unit 100, as well as electrical connections between adjacent energy storage power supply units 100. Furthermore, the energy storage power supply unit 100 of this application can also be used outdoors as a power supply base. Simply install four connection points on the bottom of products such as electric tea stoves, electric ovens, wireless charging stations, induction cookers, outdoor fans, outdoor refrigerators, outdoor coffee machines, outdoor lighting, electric bicycles, drones, and power tools to connect them to the conductive pillar assemblies 8, thus achieving electrical connection with the energy storage power supply unit 100 and effectively expanding the application scenarios of the products.

[0064] Furthermore, a first locking ring 202 is fitted at the rear end of the first soft copper wire 20, and a first locking screw 203 is threaded onto the first locking ring 202. Both the first electrical connection block 201 and the rear end of the first soft copper wire 20 are located within the first locking ring 202 and are locked in place by the first locking screw 203. Similarly, a second locking ring 302 is fitted at the rear end of the second soft copper wire 30, and a second locking screw 303 is threaded onto the second locking ring 302. Both the second electrical connection block 301 and the rear end of the second soft copper wire 30 are located within the second locking ring 302 and are locked in place by the second locking screw 303. In this application, both the first soft copper wire 20 and the second soft copper wire 30 are made of soft copper wire, allowing for movement. One end of the soft copper wire is fixed by a locking screw, while the conductive post body 81 connected to the other end can move up and down using the bending characteristics of the soft copper wire, allowing for a certain range of motion and facilitating close contact between the upper and lower conductive post bodies 81.

[0065] Furthermore, a cooling fan 40 is also provided at the rear of the module expansion compartment 11. The cooling fan 40 is electrically connected to the unit control board 12.

[0066] Furthermore, a power generation control module 50 is also provided on the top of the energy storage power supply unit 100. The power generation control module 50 includes an upper shell 501, a lower shell 502, a power generation control board 503, an electrical connection piece 504, and threaded connecting posts. The upper shell 501 and the lower shell 502 are detachably fixedly connected by threaded connecting posts 505. The power generation control board 503, the electrical connection piece 504, and the threaded connecting posts 505 are located in the cavity formed by the combination of the upper shell 501 and the lower shell 502. Four threaded connecting posts 505 are provided.
