[0032] A portable power bank (also known as a power bank or portable charger) is a portable electronic device that integrates energy storage and power supply to devices. These devices typically use lithium-ion or lithium-polymer batteries as the energy storage medium and, through built-in charge and discharge management circuits, can provide emergency power to various electronic devices such as smartphones, tablets, Bluetooth headsets, and smartwatches.

[0033] The mobile power banks in related technologies have limited functionality and cannot meet the diverse needs of users in various usage scenarios such as business travel, outdoor activities, and emergency rescue.

[0034] Reference Figure 1 , Figure 2 and Figure 3 This application provides a portable power bank, which includes a housing 1, a main circuit board 6, an energy storage component 2, a retractable cord assembly 3, and an adapter assembly 4. The energy storage component 2 is disposed inside the housing 1 and is electrically connected to the main circuit board 6. It is used to store electrical energy and output electrical energy to electrical devices. The retractable cord assembly 3 includes a retractable conductive cord 31, which is electrically connected to the main circuit board 6. At least a portion of the conductive cord 31 can extend or retract into the housing 1. The output end 311 of the conductive cord 31 is used to connect to an electrical device. The adapter assembly 4 is electrically connected to the main circuit board 6 and is used to connect to an external AC circuit and convert the AC power input from the external AC circuit into DC power.

[0035] In this embodiment, the housing 1 provides installation space and protection for the main circuit board 6, energy storage component 2, telescopic cable assembly 3, and adapter assembly 4. The housing 1 has an internal accommodating space, within which the energy storage component 2 and telescopic cable assembly 3 are housed. The adapter assembly 4 can be connected to an external circuit, and at least a portion of the adapter assembly 4 can extend from the housing for connection. The housing 1 can be made of plastic, carbon fiber composite material, or high-strength engineering plastic material, achieving both lightweight design and sufficient rigidity to withstand drops, collisions, and other accidents. The housing 1 can be a one-piece structure or a split structure. For ease of installation and maintenance, the housing 1 provided in this embodiment adopts a split structure, including an upper shell 13 and a lower shell 14. The upper shell 13 and lower shell 14 are fastened together to form the housing 1, creating an internal accommodating space.

[0036] In this embodiment, the main circuit board 6 establishes electrical connections with the energy storage component 2, the telescopic cable component 3, and the adapter component 4, respectively, so as to transfer the DC power converted by the adapter component 4 to the energy storage component 2 for storage, or to transmit the electrical energy of the energy storage component 2 to the telescopic cable component 3 for output.

[0037] In this embodiment, the energy storage component 2 can be a lithium-ion battery, a lithium polymer battery, a lithium iron phosphate battery, or a solid-state battery, used to store electrical energy and provide stable and safe power output to external electrical equipment.

[0038] In this embodiment, the retractable conductive wire 31 can be spiral-wound, spool-type, or telescopic sleeve-type, so that at least a portion of the conductive wire 31 can extend or retract into the housing 1. The output end 311 of the conductive wire 31 is located at the end of the conductive wire 31 that extends out of the housing 1, and the distance between the output end 311 and the housing 1 can be adjusted as the conductive wire 31 extends or retracts into the housing 1.

[0039] For example, the telescopic cable assembly 3 also includes a rotatable wheel core relative to the housing 1. The conductive cable 31 is wound around the wheel core. When the user applies a pulling force to the output end 311 located outside the housing 1, the wheel core rotates, and the conductive cable 31 extends out of the housing 1. When the user removes the pulling force, the conductive cable 31 can retract into the housing 1 as the wheel core rotates. To facilitate the adjustment of the extended length of the conductive cable 31, a spring and damping structure can also be provided on the wheel core.

[0040] It should be added that the output terminal 311 can integrate various types of connectors and / or wireless charging modules to meet the charging interface requirements of different devices.

[0041] In this embodiment, the housing 1 is provided with a wire-passing hole, which connects the interior and exterior of the housing 1. One end of the conductive wire 31 connected to the output terminal 311 can pass through the wire-passing hole. The output terminal 311 is located outside the housing 1. The size of the wire-passing hole can be adjusted as needed. For example, when the output terminal 311 can be retracted into the housing 1, the size of the wire-passing hole can be larger than the size of the output terminal 311; when it is not necessary to retract the output terminal 311 into the housing 1, the size of the wire-passing hole can be smaller than the size of the output terminal 311.

[0042] It should be added that electrical devices can include a variety of electronic devices such as mobile phones, tablets, Bluetooth headsets, watches, and smartwatches.

[0043] In this embodiment, the adapter component 4 is used to connect to an external AC circuit and convert the input AC power into DC power. The DC power can be used to charge the energy storage component 2, or to transmit electrical energy to the electrical device through the conductive wire 31.

[0044] In this embodiment, the adapter assembly 4 may include a plug module, which facilitates direct insertion into an AC power outlet for power supply. The plug module may integrate a rotating structure, allowing the plug angle to be adjusted to adapt to different outlet layouts and improve ease of use. The adapter assembly 4 also includes a conversion module, which can convert AC power to DC power, converting the input AC power (e.g., 220V / 50Hz or 110V / 60Hz) into DC power (e.g., 5V / 9V / 12V, etc.) suitable for charging the energy storage component 2 and powering the equipment.

[0045] The portable power bank of this application embodiment is electrically connected to the main circuit board 6 via the energy storage component 2, the conductive wire 31, and the adapter component 4. The main circuit board 6 electrically connects the energy storage component 2, the conductive wire 31, and the adapter component 4. Therefore, the energy stored in the energy storage component 2 can be directly used to power external devices, enabling power supply in mobile scenarios. Since at least a portion of the conductive wire 31 can extend or retract from the housing 1, the length of the conductive wire 31 can be flexibly adjusted according to requirements, reducing the problem of tangling and adapting to charging needs at different distances (such as charging devices over long distances). Because the housing 1 also integrates the adapter component 4, which is electrically connected to the main circuit board 6 and can be connected to an external AC circuit to convert AC power to DC power, it can directly power devices via an external AC circuit when the energy storage component 2 is depleted, while simultaneously replenishing the energy storage component 2, achieving uninterrupted power supply. With this structure, the portable power bank provided in this application embodiment can improve the versatility of portable power bank functions, thereby meeting a variety of usage scenarios, such as business trips (airport / hotel charging), outdoor camping (emergency power supply in environments without external AC circuits), and home use (flexible long-distance charging by the bedside / sofa).

[0046] Reference Figure 1 and Figure 2 In some possible embodiments of this application, along the length direction A of the housing, the housing 1 includes a first end 11 and a second end 12; the energy storage component 2 and the telescopic wire component 3 are stacked on the first end 11, and the adapter component 4 is located at the second end 12.

[0047] In this embodiment, the housing 1 has multiple extending directions, and the housing 1 has a corresponding dimension along each extending direction, wherein the extending direction corresponding to the largest dimension is the length direction A of the housing. For example, when the housing 1 is a cuboid structure, the length direction A of the housing is parallel to its edge with the largest dimension. That is, there is a large distance between the first end 11 and the second end 12 along the length direction of the housing 1.

[0048] It should be added that when the adapter component 4 is working, it needs to convert AC power to DC power, and in this process, the adapter component 4 will generate a lot of heat.

[0049] In this embodiment, both the energy storage component 2 and the telescopic wire component 3 are disposed at the first end 11, and the energy storage component 2 and the telescopic wire component 3 form a layered stacked structure. For example, along the thickness direction C of the housing, the energy storage component 2 and the telescopic wire component 3 are stacked. The stacked design can make the layout between the energy storage component 2 and the telescopic wire component 3 compact, saving internal space of the housing. When the energy storage component 2 and the telescopic wire component 3 are electrically connected, the stacked arrangement can also shorten the wiring distance.

[0050] In this embodiment of the portable power bank, the energy storage component 2 is located at the first end 11, and the adapter component 4 is located at the second end 12. This physically isolates the heat-generating adapter component 4 from the temperature-sensitive energy storage component 2 and retractable cable component 3, effectively reducing the impact of heat generated by the adapter component 4 during operation on the energy storage component 2 and retractable cable component 3. This minimizes battery performance degradation or aging of the conductive wire 31 caused by high temperatures, while simultaneously improving the operational stability and safety of the adapter component 4, energy storage component 2, and retractable cable component 3. This layout also optimizes internal space utilization, making the distribution and wiring of the adapter component 4, energy storage component 2, and retractable cable component 3 more rational and reducing electromagnetic interference.

[0051] In some possible embodiments of this application, the length direction of the energy storage component 2 is the same as that of the housing 1, and the stretching direction of the conductive wire 31 is perpendicular or parallel to the length direction of the housing 1; and / or, the adapter component 4 includes a plug-in portion 41, the plugging direction of which is perpendicular to the length direction of the housing 1.

[0052] In this embodiment, the length direction of the energy storage component 2 refers to the direction of its longest dimension. For example, see [reference]. Figure 1 When the housing 1 is elongated, the energy storage component 2 is also arranged along the long axis of the housing 1. In this way, the energy storage component 2 can be adapted to the shape of the housing 1, the layout of the energy storage component 2 within the housing 1 can be optimized, and the space occupied can be reduced.

[0053] In this embodiment, the stretching direction of the conductive wire 31 is parallel to the length direction of the housing 1, or the stretching direction of the conductive wire 31 is perpendicular to the length direction of the housing 1. Different stretching directions of the conductor points can be selected according to the usage scenario, which improves the adaptability of the conductive wire 31, reduces the need for bending of the conductive wire 31 in different usage scenarios, reduces wear on the conductive wire 31, and improves the convenience of use.

[0054] In this embodiment, the plug part 41 is used to connect to the socket of an external AC circuit. The plug-in direction of the plug part 41 is perpendicular to the length direction of the housing 1. In this way, when the plug part 41 is inserted into the socket, the side of the housing 1 in the length direction is located on the side of the surface (wall, etc.) around the socket, which can reduce the end of the housing 1 away from the socket from extending too far and reduce the risk of collision.

[0055] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In some possible embodiments of this application, the portable power bank further includes a functional component 7, which is located at the second end 12 and is located on a different side of the housing 1 from the adapter component 4; wherein the functional component 7 is at least electrically connected to the main circuit board 6, the functional component 7 is used for human-computer interaction, and / or, the functional component 7 is used for electrically connecting to an electrical device, and / or, the functional component 7 is used for electrically connecting to an external DC circuit.

[0056] In this embodiment, the functional component 7 may include a display module 72, a control module 73, and an output interface 71. For example, the display module 72 can be used to display parameters such as remaining battery power, charging / discharging power, and temperature in real time. The housing 1 may also include a light-transmitting element 16, through which the light from the display module 72 can pass. The control module 73 can be used to adjust the output mode (such as fast charging / normal charging switching) and toggle the wireless charging function on / off. The output interface 71 can be used to connect more electrical devices.

[0057] In this embodiment, the functional component 7 is located at the second end 12, that is, the functional component 7 and the adapter component 4 are disposed on the same side of the housing 1 in the length direction. The fact that the functional component 7 and the adapter component 4 are located on different sides of the housing 1 can be understood as the functional component 7 and the adapter component 4 being arranged on two opposite sides of the second end 12 of the housing 1, or the functional component 7 and the adapter component 4 being arranged on adjacent sides of the second end 12 of the housing 1.

[0058] The portable power bank of this application embodiment, since it also includes a functional component 7, can have extended functions such as power visualization, multi-device collaborative charging, and environmental parameter monitoring. Because the functional component 7 and the adapter component 4 are located on different sides of the housing 1, the functional component 7 and the adapter component 4 will not interfere with each other, especially reducing the impact of the adapter component 4's temperature on the functional component 7 during operation; furthermore, when the adapter component 4 is plugged into a socket for charging, it reduces obstruction of the functional component 7, making it easier to observe or control the functional component 7.

[0059] Reference Figure 1 , Figure 3 and Figure 6In some possible embodiments of this application, the portable power bank also includes a support frame 5, which is fixed inside the housing 1. The support frame 5 includes a first fixing plate 51, and the energy storage component 2 and the telescopic cable component 3 are respectively fixed to different sides of the first fixing plate 51.

[0060] In this embodiment, the support frame 5 provides an installation foundation and support for the energy storage component 2 and the telescopic cable assembly 3. The support frame 5 can be a plate structure, a frame structure, or a honeycomb sandwich structure, etc. The support frame 5 can be installed inside the housing 1 by means of snap-fit ​​fixing, screw fastening, or welding. The energy storage component 2 and the telescopic cable assembly 3 can be symmetrically distributed on both sides of the support frame 5, arranged in upper and lower layers, or installed in a staggered manner. The adapter assembly 4 being arranged adjacent to the support frame 5 means that the adapter assembly 4 is arranged on one side edge adjacent to the support frame 5, forming a spatial layout relationship similar to an L-shape or a T-shape with the support frame 5.

[0061] In this embodiment, the first fixing plate 51 extends along the length direction A of the shell and divides the internal space of the shell 1 into two spaces in the thickness direction. The energy storage component 2 is disposed in one space, and the telescopic wire component 3 is disposed in the other space. The first fixing plate 51 can be a reinforcing rib structure, a honeycomb sandwich panel structure, or a metal partition structure with heat dissipation holes.

[0062] The portable power bank of this application embodiment features a support frame 5 inside the housing 1, which enhances the structural strength of the housing 1 and improves its impact and deformation resistance. Since the energy storage component 2 and the retractable cable assembly 3 are located on different sides of the first fixing plate 51, a modular, partitioned layout of the components inside the housing 1 is achieved, facilitating heat dissipation management and maintenance / replacement. The first fixing plate 51 also provides stable support and restraint for the positions of the energy storage component 2 and the retractable cable assembly 3 within the housing 1, reducing their swaying within the housing 1 in the event of collisions or drops. The adapter assembly 4 and the support frame 5 are arranged adjacent to each other, providing support and restraint for the adapter assembly 4. Simultaneously, the support frame 5 can be used as a heat conduction medium to aid in heat dissipation for the adapter assembly 4.

[0063] Reference Figure 6 and Figure 7 In some possible embodiments of this application, the telescopic cable assembly 3 includes a housing 33 and a winding assembly; the first surface 511 of the first fixing plate 51 is provided with a positioning post 512 and a fixing member, and the housing 33 cooperates with the fixing member to fix the telescopic cable assembly 3; the positioning post 512 is inserted into the winding assembly to position the winding assembly; and / or, the first surface 511 of the first fixing plate 51 is provided with a groove, the telescopic cable assembly 3 includes a first circuit board and a winding assembly, the first circuit board is fixed in the groove, the first end of the first circuit board is electrically connected to the main circuit board 6, and the second end of the first circuit board is electrically connected to the winding assembly.

[0064] In this embodiment, a space for mounting the winding assembly is formed between the outer shell 33 and the first fixing plate 51. The outer shell 33 and the first fixing plate 51 provide a mounting base and protection for the winding assembly to reduce the spread of the conductive wires 31 of the winding assembly or its impact on other components inside the shell 1. The outer shell 33 has an opening on the side facing the first fixing plate 51. The first fixing plate 51 can form a sidewall of the opening to cover it. It can also be understood that the fixing plate is part of the structure of the outer shell 33, which can reduce the material consumption of the outer shell 33 and further reduce the space occupied by the shell 1.

[0065] In this embodiment, the first surface 511 of the first fixing plate 51 faces the winding assembly. A positioning post 512 is provided on the first surface 511. The conductive wire 31 of the winding assembly is wound around the outer periphery of the positioning post 512, allowing the conductive wire 31 to be released or wound around the positioning post 512. The positioning post 512 can also limit the conductive wire 31. The winding assembly may also include a wheel core, with the conductive wire 31 wound around the outer periphery of the wheel core. The wheel core can be fitted onto the positioning post 512 and can rotate around the positioning post 512, allowing the conductive wire 31 to be released and retracted through the rotation of the wheel core.

[0066] In this embodiment, the fastener refers to a mechanical structure or connecting component used to securely mount the telescopic cable assembly 3 (including the housing 33 and the winding assembly) onto the first fixing plate 51. The fastener cooperates with the housing 33 to reduce loosening or displacement of the telescopic cable assembly 3 inside the housing 1; the fastener can also provide mechanical support to keep the winding assembly stable when the conductive wire 31 is stretched or retracted. The fastener can be a combination of holes and bolts, using bolts to lock the housing 33 onto the first fixing plate 51; the fastener can also be a metal spring or a plastic clip, clamping the edge of the housing 33 for fixation.

[0067] In this embodiment of the application, the first end of the first circuit board is electrically connected to the main circuit board 6. The first end of the first circuit board and the main circuit board 6 can be electrically connected by soldering; they can also be detachably electrically connected by connecting pin headers and female headers; or they can be connected in other ways.

[0068] In this embodiment, the first surface 511 of the first fixing plate 51 is machined with a groove for embedding and fixing the first circuit board, reducing displacement of the first circuit board or interference with other components. The depth and shape of the groove may match the thickness and shape of the first circuit board to achieve flush mounting between the first circuit board and the groove, reducing the possibility of the first circuit board coming out.

[0069] In this embodiment, the second end of the first circuit board is electrically connected to the winding assembly. The winding assembly can also follow the circuit board. The following circuit board electrically connects the conductive wire 31 to the first circuit board or the main circuit board 6, thereby electrically connecting the conductive wire 31 to the components connected to the main circuit board 6 inside the housing 1, such as the energy storage component 2 and the functional component 7. The following circuit board can rotate relative to the first circuit board or the main circuit board 6 with the movement of the wheel core.

[0070] For example, when the follower circuit board is electrically connected to the first circuit board, the first circuit board is electrically connected to the main circuit board 6. The follower circuit board has at least two sets of 5-pin connectors soldered on it. The first circuit board has 5 copper rings in the middle. The follower circuit board is connected to the 5 copper rings of the first circuit board through the 5-pin connectors, so that the follower circuit board can rotate and be electrically connected relative to the first circuit board.

[0071] In this embodiment, the winding assembly may further include a gear damping assembly and a spring reset assembly, so that the conductive wire 31 can be locked at any length after extending out of the housing 1, reducing the rebound of the conductive wire 31 and improving stability; the spring reset assembly is used to provide the power for winding, so that the transmission line can be automatically retracted to be wound onto the corresponding wheel core. For example, the gear damping assembly may include a swivel wheel, a rocker arm, and a spring clip. The swivel wheel may be fixed to the side of the conductive wire 31 facing the first fixed plate 51, and the swivel wheel rotates synchronously with the wheel core. The rocker arm and the spring clip are fixed to the housing 33 or the first fixed plate 51.

[0072] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In some possible embodiments of this application, the portable power bank also includes a functional component 7 for human-computer interaction. The support frame 5 includes a second fixing plate 52. Along the width direction B of the housing, the functional component 7 and the adapter assembly 4 are fixed to different sides of the second fixing plate 52. The energy storage component 2 and the telescopic cable assembly 3 are respectively fixed to different sides of the first fixing plate 51 along the thickness direction of the housing 1.

[0073] In this embodiment, the second fixing plate 52 extends along the width direction B of the shell, and the second fixing plate 52 can be a frame structure, a grid support structure, etc.

[0074] In this embodiment of the application, the housing 1 has multiple extension directions, and the housing 1 has a corresponding size along each extension direction. The extension direction corresponding to the largest size is the length direction A of the housing; the extension direction corresponding to the smallest size is the thickness direction C of the housing; the size of the width direction B of the housing is greater than the size of the thickness direction of the housing 1 and less than the size of the length direction.

[0075] In this embodiment, the functional component 7 and the adapter component 4 are located on different sides of the support frame 5 along the width direction B of the housing. This means that the support frame 5 divides the internal space of the housing 1 into two opposing regions along the width direction B of the housing, and the functional component 7 and the adapter component 4 are respectively disposed in these two regions, thereby connecting the functional component 7 and the adapter component 4.

[0076] In this embodiment, the energy storage component 2 and the telescopic cable component 3 are located on different sides of the support frame 5 along the thickness direction C of the shell. This means that the support frame 5 isolates the internal space of the shell 1 into two opposing regions along the thickness direction C of the shell. It can also be understood that the support frame 5 isolates the internal space of the shell 1 into upper and lower layers of space, and the energy storage component 2 and the telescopic cable component 3 are respectively set in these two regions, thereby spatially separating the energy storage component 2 and the telescopic cable component 3.

[0077] The portable power bank of this application embodiment can divide the internal space of the housing 1 into four regions in the width and thickness directions, and respectively arrange the functional component 7, adapter component 4, energy storage component 2 and retractable cable component 3 in the four spaces. This optimizes the distribution of the internal space of the housing 1, optimizes the internal wiring path, improves the stability of the functional component 7, adapter component 4, energy storage component 2 and retractable cable component 3 inside the housing 1, and reduces the shaking and mutual interference of the internal structure of the housing 1.

[0078] It should be added that functional component 7 may include a display module 72, a control module 73, and an output interface 71, etc. For example, the display module 72 can be used to display parameters such as remaining power, charging and discharging power, and temperature in real time. The housing 1 may also include a light-transmitting element 16, through which the light from the display module 72 can pass; the control module 73 can be used to adjust the output mode (such as fast charging / normal charging switching) and toggle the wireless charging function; the output interface 71 can be used to connect more electrical devices, etc.

[0079] Reference Figure 1 , Figure 2 and Figure 3 In some possible embodiments of this application, the portable power bank further includes a support frame 5 and a functional component 7. The support frame 5 is fixed inside the housing 1, and the functional component 7 is used for human-computer interaction. The support frame 5 includes a first fixing plate 51 and a second fixing plate 52. The first fixing plate 51 is disposed between the energy storage component 2 and the telescopic cable component 3, and the first fixing plate 51 forms a limiting structure 15 corresponding to at least one of the energy storage component 2 and the telescopic cable component 3. The second fixing plate 52 is in a different direction from the first fixing plate 51, and the second fixing plate 52 forms a space for accommodating the functional component 7.

[0080] In this embodiment, the first fixing plate 51 may form a limiting structure 15 corresponding to at least one of the energy storage component 2 and the telescopic component 3, or it may form a limiting structure 15 corresponding to both the energy storage component 2 and the telescopic component 3. For the energy storage component 2, the limiting structure 15 may be a surrounding protrusion or an anti-slip silicone pad, etc., along the circumference of the energy storage component 2; for the telescopic component 3, the limiting structure 15 may be a guide groove or a positioning buckle, etc.

[0081] In this embodiment, the second fixing plate 52 extends along the width direction B of the housing. The second fixing plate 52 can be a frame structure, a grid support structure, etc., thereby forming a space to accommodate the functional components 7 within the second fixing plate 52. For example, a slot for the control main circuit board 6 is provided in the middle of the space formed by the second fixing plate 52, and an expansion interface reservation, button, display screen, etc. are provided on the side of the space formed by the second fixing plate 52.

[0082] In the portable power bank of this application embodiment, the first fixing plate 51 can be used to resist the extrusion deformation of the shell 1 in the thickness direction and the length direction, and the second fixing plate 52 can enhance the bending strength of the shell 1 in the width direction. The first fixing plate 51 and the second fixing plate 52 form a three-dimensional support frame similar to a "cross".

[0083] Reference Figure 1 and Figure 6 In some possible embodiments of this application, the portable power bank also includes a main circuit board 6, one end of which is disposed between the adapter assembly 4 and the functional component 7 along its length, and the other end of which is disposed adjacent to the retractable cable assembly 3; the energy storage component 2, the retractable cable assembly 3, the adapter assembly 4 and the functional component 7 are all electrically connected to the main circuit board 6.

[0084] In this embodiment, the length direction of the main circuit board 6 is consistent with the length direction A of the housing. One end of the main circuit board 6 is mounted on the second fixing plate 52 between the adapter assembly 4 and the functional component 7. The second fixing plate 52 provides a mounting base for the main circuit board 6. The other end of the main circuit board 6 is adjacent to the telescopic cable assembly 3.

[0085] In the portable power bank of this application embodiment, since one end of the main circuit board 6 is located between the adapter assembly 4 and the functional component 7, it is convenient for the adapter assembly 4 and the functional component 7 to be electrically connected to the main circuit board 6. The retractable cable assembly 3 is connected to the other end of the main circuit board 6, which can avoid the connection between the adapter assembly 4 and the functional component 7 and the main circuit board 6, thereby reducing interference between the components.

[0086] Reference Figure 1In some possible embodiments of this application, the portable power supply further includes a conductive harness 8 connected to a third end 61 of the main circuit board 6, the third end 61 being disposed away from the energy storage component 2; the adapter component 4 and the functional component 7 are electrically connected to the main circuit board 6 via the conductive harness 8.

[0087] In this embodiment of the portable power bank, since the third end 61 is positioned far from the energy storage component 2, the conductive wire 31 can maintain a large distance from the energy storage component 2, reducing the temperature-related influence between the conductive wire harness 8 and the energy storage component 2. The conductive wire harness 8 is connected to the third end 61 of the main circuit board 6, which is equivalent to the conductive wire harness 8 being arranged along the edge of the housing 1, allowing the conductive wire harness 8 to avoid heat dissipation areas and optimizing the wiring path.

[0088] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 In some possible embodiments of this application, the portable power supply further includes an output interface 71 and a second circuit board 9. The output interface 71 is used to connect to an electrical device and is electrically connected to the second circuit board 9. The second circuit board 9 is fixed to the main circuit board 6 and / or the second circuit board 9 is fixed to the support frame 5. The adapter assembly 4 includes a plug-in portion 41 and a third circuit board 42. The plug-in portion 41 is used to connect to a plug socket for an external AC circuit and is electrically connected to the third circuit board 42. The third circuit board 42 is fixed to the main circuit board 6 and / or the third circuit board 42 is fixed to the support frame 5. The second circuit board 9 and the third circuit board 42 are respectively electrically connected to the main circuit board 6. The extension direction of the second circuit board 9 and the third circuit board 42 both extend along a first direction, and the first direction is perpendicular to the extension direction of the main circuit board 6.

[0089] In this embodiment, the second circuit board 9 and the third circuit board 42 are electrically connected to the main circuit board 6, thereby electrically connecting the output interface 71 and the plug-in part 41 to the main circuit board 6, forming an electrical circuit between the plug-in part 41 and the output interface 71. The second circuit board 9 can integrate circuits such as voltage conversion and overcurrent protection. The second circuit board 9 is fixed on the main circuit board 6 or the support frame 5 to enhance structural stability and reduce poor contact caused by vibration or movement.

[0090] In this embodiment, the third circuit board 42 is electrically connected to the plug-in part 41. The third circuit board 42 can integrate rectifier, filter and other circuits to convert AC power into DC power. The third circuit board 42 is fixed on the main circuit board 6 or the support frame 5 to improve the stability of the third circuit board 42.

[0091] In this embodiment, the first direction is the extension direction of the second circuit board 9 and the third circuit board 42, that is, the extension directions of the second circuit board 9 and the third circuit board 42 are both parallel to the first direction. For example, the first direction can be the thickness direction of the housing 1, and the main circuit board 6 extends along a possible length direction. The first direction extends perpendicular to the main circuit board 6, which can form a three-dimensional structure layout between the second circuit board 9, the third circuit board 42 and the main circuit board 6, optimizing the stability of the internal structure of the housing 1; making full use of three-dimensional space, it also improves the compactness of the internal structure of the housing 1.

[0092] In some possible embodiments of this application, the portable power bank also includes a support frame 5 connected inside the housing 1, and the main circuit board 6 includes at least two sub-boards, which are respectively connected to opposite sides of the support frame 5.

[0093] In this embodiment, there can be multiple sub-boards, each with its own independent function. For example, a sub-board may include a main control sub-board, a power sub-board, and expansion sub-boards for other functions. Two sub-boards can be used to connect opposite sides of the support frame 5, and multiple sub-boards can be electrically connected to each other.

[0094] The portable power bank of this application embodiment, since at least two sub-boards are respectively connected to opposite sides of the support frame 5, allows for independent optimization and layout of each sub-board, enabling them to be distributed and reducing heat accumulation. Simultaneously, the gaps between the sub-boards can form heat dissipation channels, improving heat dissipation. Dividing the main circuit board 6 into multiple sub-boards also facilitates maintenance; in case of failure, only the damaged sub-board needs to be replaced or repaired.

[0095] Reference Figure 1 , Figure 2 and Figure 6 In some possible embodiments of this application, the housing 1 includes a receiving groove 17, the opening of which is located on the outer surface of the housing 1. The adapter assembly 4 includes a plug part 41 for connecting a plug socket of an external AC circuit. The plug part 41 is movably connected to the housing 1 and has a retracted state in which it is accommodated in the receiving groove 17 and an extended state in which it partially protrudes from the receiving groove 17.

[0096] In this embodiment, the movable connection between the plug-in portion 41 and the housing 1 can be a rotary connection, a sliding connection, or the like. For example, in the case of a rotary connection between the plug-in portion 41 and the housing 1, the plug-in portion 41 rotates relative to the housing 1, allowing the plug-in portion 41 to be adjusted between a retracted state and an unfolded state.

[0097] In this embodiment, when the plug part 41 needs to be connected to an external circuit socket, the plug part 41 is adjusted to an unfolded state; when the plug part 41 does not need to be connected to an external circuit socket, the plug part 41 can be rotated to a state where it is housed in the receiving groove 17.

[0098] In this embodiment, the shape and size of the receiving groove 17 can be adjusted according to the shape and size of the plug part 41 so that the plug part 41 can be housed in the receiving groove 17.

[0099] The portable power bank of this application embodiment improves the flexibility of the plug-in part 41 because the plug-in part 41 can be in a retracted state or an unfolded state relative to the receiving slot 17, and the state of the plug-in part 41 can be adjusted according to needs.
