Description

Technical Field

[0001] This application relates to, but is not limited to, the field of electronic device technology, and in particular to a portable power bank. Background Technology

[0002] Portable power banks, also known as power banks or chargers, are used to store electrical energy and provide power to various electronic devices. However, current portable power banks often lack a sturdy handle, making them inconvenient to carry and requiring considerable storage space. Utility Model Content

[0003] The portable power bank provided in this application can achieve multi-functional switching of the conductive wire, and when needed, the conductive wire can form a stable handle for carrying or hanging, thus taking into account portability, storage and stability of use.

[0004] This application provides a portable power bank, which includes a housing, a telescopic component, and a limiting structure. The housing has an accommodating space; the telescopic component is disposed within the accommodating space and includes a retractable conductive wire and at least two connecting portions. At least a portion of the conductive wire can extend or retract into the accommodating space, and the interface end of the conductive wire is used to connect to an electrical device; the portion of the conductive wire extending out of the housing includes a flexible segment located between two adjacent connecting portions; the limiting structure is disposed on the housing, and at least two connecting portions are detachably connected to the limiting structure. When the limiting structure is connected to the connecting portions, the two ends of the flexible segment are fixed relative to the housing to form a handle for suspension.

[0005] The portable power bank provided in this application allows for flexible adjustment of the conductive wire length to suit different usage scenarios, as at least a portion of the conductive wire in the telescopic assembly can extend or retract into the receiving space. Since the portion of the conductive wire extending from the housing includes a flexible section located between two adjacent connecting parts, the two ends of the flexible section are fixed relative to the housing when the two connecting parts and the limiting structure are connected. This allows the flexible section to form a handle for hanging or carrying, facilitating the portable power bank's transport or storage. When the connecting parts are detached from the limiting structure, the flexible section can be retracted into the receiving space for storage or connected to a power device using an interface. The connection between the limiting structure and the connecting parts, fixing the two ends of the flexible section relative to the housing, improves the stability of the handle during use, preventing deformation or loosening under load. This structure enables the portable power bank to achieve multi-functional switching of the conductive wire, allowing it to form a stable handle for carrying or hanging when needed, thus balancing portability, storage, and stability.

[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] Portable power banks in related technologies lack a sturdy handle, making them inconvenient to carry and requiring a large storage space.

[0034] Reference Figure 1 , Figure 2 and Figure 6 This application provides a portable power bank, which includes a housing 1, a telescopic component 2, and a limiting structure 3. The housing 1 has an accommodating space; the telescopic component 2 is disposed within the accommodating space, and the telescopic component 2 includes a retractable conductive wire 21 and at least two connecting portions (e.g., Figure 2 The first connecting part 22 and the second connecting part 23) are described. At least a portion of the conductive wire 21 can extend or retract into the receiving space. The interface end of the conductive wire 21 is used to connect to electrical equipment. The portion of the conductive wire 21 extending out of the housing 1 includes a flexible segment 211, which is located between two adjacent connecting parts. A limiting structure 3 is provided on the housing 1. At least two connecting parts are detachably connected to the limiting structure 3. When the limiting structure 3 is connected to the connecting part, the two ends of the flexible segment 211 are fixed relative to the housing 1 to form a handle for suspension.

[0035] In this embodiment, the housing 1 provides an installation foundation and protection for the energy storage component, the telescopic component 2, and the limiting structure 3. The housing 1 has an internal accommodating space, within which the energy storage component and the telescopic component 2 are housed. The housing 1 can be made of plastic, carbon fiber composite material, or high-strength engineering plastic material, ensuring both lightweight construction and sufficient rigidity to withstand drops, collisions, and other unexpected events. 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 and a lower shell, which are fastened together to form the housing 1, creating an internal accommodating space.

[0036] In this embodiment, the retractable conductive wire 21 can be spiral-wound, spool-type, or telescopic sleeve-type, so that at least a portion of the conductive wire 21 can extend or retract into the housing 1. The interface end of the conductive wire 21 is located at the end of the conductive wire 21 that extends out of the housing 1, and the distance between the interface end and the housing 1 can be adjusted as the conductive wire 21 extends or retracts into the housing 1.

[0037] Reference Figure 2 In this embodiment, the telescopic component 2 further includes a wheel core 24 rotatable relative to the housing 1. A conductive wire 21 is wound around the wheel core 24. When the user applies tension to the conductive wire 21 located outside the housing 1, the wheel core 24 rotates, and the conductive wire 21 extends out of the housing 1. When the user removes the tension, the conductive wire 21 retracts into the housing 1 as the wheel core 24 rotates. To more conveniently adjust the length of the extended conductive wire 21, a spring and damping structure can also be provided on the wheel core 24.

[0038] It should be added that the interface can integrate various types of connectors and / or wireless charging modules to meet the charging interface requirements of different devices. These devices can include mobile phones, tablets, Bluetooth headsets, watches, smartwatches, and other electronic devices.

[0039] In this embodiment, the housing 1 is provided with a wire passage, which is used to connect the inside of the housing 1 and the outside of the housing 1. One end of the conductive wire 21 connected to the interface end can pass through the wire passage, and the interface end is located outside the housing 1. The size of the wire passage can be adjusted according to the requirements.

[0040] In this embodiment, at least two connecting parts are provided on the part of the conductive line 21 that extends out of the housing 1. The connecting parts can be retracted into the receiving space or connected to the limiting structure 3 so that the conductive line 21 between the connecting part and the interface end cannot be retracted into the receiving space.

[0041] Reference Figure 1 and Figure 6In this embodiment of the application, the conductive wire 21 between two adjacent connecting parts forms a flexible segment 211. After the two connecting parts at both ends of the flexible segment 211 are connected to the limiting structure 3, the positions of the two ends of the flexible segment 211 relative to the housing 1 are fixed. Thus, the flexible segment 211 can be used as a handle for hanging or carrying.

[0042] It should be added that the limiting structure 3 in this application can be a slot type, a magnetic type, a knob lock type, or a hook type; the connecting part can be adjusted according to different limiting structures 3. When the limiting structure 3 is a slot type, the connecting part can be a protruding buckle or a T-shaped slider structure. When it is a magnetic type, the connecting part can be a metal contact structure with embedded permanent magnets. When the limiting structure 3 is a knob lock type, the connecting part can be a threaded sleeve structure. When the limiting structure 3 is a hook type, the connecting part can be a ring buckle or a J-shaped hook structure. In order to make the conductive wire 21 usable as a handle, at least the outer layer of the flexible section 211 of the conductive wire 21 can be made of materials such as silicone or rubber, so that it can be bent into an arc suitable for gripping or hanging, and can also have sufficient strength. Other parts of the conductive wire 21 that can be retracted into the receiving space can be made of the same material as the flexible section 211, or can be adjusted according to needs.

[0043] For example, the side of the housing 1 may be provided with symmetrical slot-type limiting structures 3, each limiting structure 3 including a pressable elastic buckle and a corresponding snap-fit ​​groove. The conductive wire 21 is provided with multiple connecting parts made of rigid plastic material (such as ring buckles) at intervals, and the conductive wire 21 between adjacent connecting parts is a flexible segment 211 covered with flexible silicone. When a handle is needed, the conductive wire 21 is pulled out from the housing 1, aligning two adjacent connecting parts with the limiting structures 3 on both sides of the housing 1. The connecting part is pressed to embed into the snap-fit ​​groove, and the elastic buckle automatically springs back to lock the connecting part. At this time, the flexible segment 211 between the two connecting parts is in a suspended arc shape, and its ends cannot move due to the fixed connecting parts, forming a stable handle structure.

[0044] In another embodiment, the upper limit structure 3 of the housing 1 has a U-shaped groove. When the connecting part is connected to the limit structure 3, the flexible segment 211 is a straight line located between two adjacent connecting parts, and the two ends of the flexible segment 211 are fixed relative to the position of the housing 1. In this way, the space formed between the groove and the flexible segment 211 can form a space for fingers to pass through or for suspension.

[0045] In this embodiment, there can be multiple connecting parts, which are distributed at intervals along the flexible segment 211. Two different connecting parts are connected to the limiting structure 3, which can make the flexible segment 211 form handles of different sizes.

[0046] In this embodiment of the portable power bank, since at least a portion of the conductive wire 21 in the telescopic component 2 can extend or retract into the receiving space, the length of the conductive wire 21 can be flexibly adjusted according to usage requirements to adapt to different scenarios. Since the portion of the conductive wire 21 extending out of the housing 1 includes a flexible segment 211, and the flexible segment 211 is located between two adjacent connecting parts, when the two connecting parts and the limiting structure 3 are connected, the two ends of the flexible segment 211 are fixed relative to the housing 1. Thus, the flexible segment 211 can form a handle for hanging or carrying, so as to facilitate carrying the portable power bank or hanging it for storage. When the connecting parts are detached from the limiting structure 3, the flexible segment 211 can be retracted into the receiving space for storage, or connected to the power device using the interface end. Since the limiting structure 3 and the connecting parts are connected, fixing the two ends of the flexible segment 211 relative to the housing 1 can improve the stability of the handle during use, making the handle less prone to deformation or loosening when bearing weight. With this structure, the portable power bank can achieve multi-functional switching of the conductive wire 21, and when needed, the conductive wire 21 can form a stable handle for carrying or hanging, thus taking into account portability, storage and stability of use.

[0047] Reference Figure 2 , Figure 3 and Figure 4 In some possible embodiments of this application, at least two connecting portions include a first connecting portion 22, and the limiting structure 3 includes a first limiting member 31; the first limiting member 31 is fixed relative to the housing 1, the first limiting member 31 is elastically configured, and the first limiting member 31 abuts against the first connecting portion 22 under the action of elastic force to limit the movement of the first connecting portion 22 relative to the housing 1; or, the first limiting member 31 is movably connected to the housing 1, and the first limiting member 31 can move relative to the housing 1 to a first position and a second position. In the first position, the first limiting member 31 abuts against the first connecting portion 22 to limit the movement of the first limiting member 31 relative to the housing 1, and in the second position, the first limiting member 31 is separated from the first connecting portion 22.

[0048] In this embodiment, the first limiting member 31 can be an elastic element (such as a spring sheet, a helical spring, or an elastic rubber block); the first limiting member 31 can also be connected to the housing 1 through an elastic element, so that the limiting member can generate elastic displacement when subjected to external force, and automatically reset after the external force is removed.

[0049] In this embodiment, the first limiting member 31 may also rotate or slide relative to the housing 1, so that the first limiting member 31 can abut against the first connecting part 22 under the action of the first limiting member 31, thereby restricting the movement of the first connecting part 22 relative to the housing 1.

[0050] For example, when the first limiting member 31 is slidably connected to the housing 1, the first limiting member 31 can move toward or away from the first connecting part 22 relative to the housing 1. The first limiting member 31 slides toward the direction where the first connecting part 22 is located and moves to a position that abuts against the first connecting part 22, which is the first position; the first limiting member 31 slides away from the first connecting part 22 and moves to a position that separates from the first connecting part 22, which is the second position.

[0051] In another embodiment, the first limiting member 31 is rotatable relative to the housing 1. One end of the first limiting member 31 is rotatably connected to the housing 1, and the other end is rotatable around the connected end. When the first limiting member 31 rotates to a position abutting against the first connecting part 22, it can restrict the position of the first connecting part 22 relative to the housing 1. When the first limiting member 31 rotates to a position separated from the first connecting part 22, the first connecting part 22 can move relative to the housing 1.

[0052] In this embodiment of the portable power bank, the first limiting member 31 is elastically designed, allowing it to abut against the first connecting part 22 under the action of elastic force, thereby limiting the first connecting part 22. Because the first limiting member 31 is designed to move relative to the housing 1, it can switch between the limiting position and the release position in multiple different ways. This enables the first limiting member 31 to respond quickly and improves the stability of its limiting effect on the first connecting part 22. When limiting the first connecting part 22 is not required, the first connecting part 22 can be quickly released from the first limiting member 31.

[0053] Reference Figure 2 , Figure 3 and Figure 4 In some possible embodiments of this application, the limiting structure 3 further includes a fixing seat 32, which is connected to the housing 1, and the first limiting member 31 is connected to the fixing seat 32; the opposite sides of the first connecting part 22 abut against different positions of the first limiting member 31; or, the opposite sides of the first connecting part 22 abut against the first limiting member 31 and the fixing seat 32 respectively.

[0054] In this embodiment, the fixing seat 32 provides support for the first limiting member 31 and fixes the position of the first limiting member 31 relative to the housing 1. The fixing seat 32 can be made of metal stamping or engineering plastic injection molding, and is connected to the housing 1 by means of screw locking, snap connection or welding.

[0055] In this embodiment, two independent first limiting members 31 can be symmetrically arranged on the fixed base 32, so that the opposite sides of the first connecting part 22 abut against the two independent first limiting members 31 respectively; or a first limiting member 31 can be arranged on the fixed base 32, and the first limiting member 31 extends to the opposite sides of the first connecting part 22, so that the opposite sides of the first connecting part 22 abut against the first limiting structure 3 respectively, thereby restricting the position of the first connecting part 22.

[0056] In this embodiment, the fixed base 32 may be provided with only one first limiting member 31, and the first limiting member 31 abuts against one side of the first connecting part 22 and applies pressure to the first connecting part 22. The other side of the first connecting part 22 abuts against the fixed base 32 under the action of pressure. Under the combined action of the fixed base 32 and the first limiting member 31, the position of the first connecting part 22 relative to the housing 1 is defined.

[0057] In another embodiment, the limiting structure 3 may not include the fixing seat 32. The first limiting member 31 abuts against one side of the first connecting part 22 and applies pressure to the first connecting part 22. The other side of the first connecting part 22 abuts against the housing 1 under the action of pressure. Under the combined action of the housing 1 and the first limiting member 31, the position of the first connecting part 22 relative to the housing 1 is defined.

[0058] In this embodiment of the portable power bank, the fixing base 32 connects the first limiting member 31 and the housing 1, thereby improving the stability of the first limiting member 31. The opposite sides of the first connecting part 22 abut against the first limiting member 31, or the opposite sides of the first connecting part 22 abut against the first limiting member 31 and the fixing base 32 respectively, which can limit the first connecting part 22 on the opposite sides of the first connecting part 22, thereby improving the stability and reliability of the first connecting part 22 relative to the housing 1 and reducing the risk of the first connecting part 22 loosening under force.

[0059] Reference Figure 2 , Figure 3 and Figure 4 In some possible embodiments of this application, the fixing base 32 is provided with a wire harness channel 321, which connects the accommodating space and the outer side of the housing 1. The conductive wire 21 passes through the wire harness channel 321. Along the axial direction of the wire harness channel 321, a first limiting member 31 is provided at the end of the fixing base 32. The first limiting member 31 is provided on the inner wall of the wire harness channel 321. The fixing base 32 is provided with a through hole 322 corresponding to the middle part of the wire harness channel 321, and part of the first limiting member 31 extends into the wire harness channel 321 through the through hole 322.

[0060] In this embodiment, along the axial direction of the wire harness channel 321, a first limiting member 31 is disposed at the end of the fixing seat 32. The first limiting member 31 may include the end face of the fixing seat 32. When it is necessary to limit the first connecting part 22, the first connecting part 22 is accommodated in the wire harness channel 321 of the fixing seat 32. The end face of the first connecting part 22 near the outside of the housing 1 abuts against the end face of the fixing seat 32, so that the first connecting part 22 is stuck in the wire harness channel 321, so that the flexible segment 211 is subjected to force and the first connecting part 22 is stuck in the wire harness channel 321.

[0061] In another embodiment, along the axial direction of the wire harness channel 321, the first limiting member 31 is disposed on the inner wall of the wire harness channel 321. In this case, one or more sides of the inner wall of the wire harness channel 321 corresponding to the first connecting part 22 are provided with structures that can be adapted to the first limiting member 31, such as protrusions and grooves, buckles and slots, etc. When it is necessary to limit the first connecting part 22, the first connecting part 22 is housed in the wire harness channel 321 of the fixing seat 32, and the first limiting member 31 achieves radial limitation of the first connecting part 22.

[0062] In another embodiment, the fixing base 32 has a through hole 322 in the middle of the wire harness channel 321. The part of the first limiting member 31 that extends into the wire harness channel 321 through the through hole 322 can contact the first connecting part 22 and be used to limit the first connecting part 22.

[0063] Reference Figure 2 , Figure 3 and Figure 4 In some possible embodiments of this application, the fixing base 32 is provided with two through holes 322, which are symmetrically arranged about the axis of the wire harness channel 321; the first limiting member 31 includes a fixing part and two extension parts 313, which are arranged one-to-one with the two through holes 322. The fixing part is connected to the fixing base 32, and the extension parts 313 extend from the fixing part to the corresponding through holes 322.

[0064] In this embodiment, the extension 313 can be made into an arc or wave shape using a specific stamping process, so that it can elastically deform within a suitable range when the conductive wire 21 extends or retracts, providing sufficient rebound force to assist the conductive wire 21 in resetting and limiting its position. The proximal end of the extension 313 is connected to the fixing part, and the distal end of the extension 313 extends along an arc trajectory into the through hole 322.

[0065] The extension portion 313 can be made of a flexible material, such as metal or plastic. For example, the extension portion 313 can be made of resilient manganese steel. The extension portion 313 is a resilient manganese steel sheet. The extension portion 313 can be fixed on the fixing base 32 by heat fusion, or it can be connected to the fixing base 32 by the fixing part, so that the manganese steel sheet will not loosen or shift during frequent operation of the conductive wire 21. Manganese steel is a high-strength alloy steel, and the manganese steel material selected for the resilient manganese steel sheet has good elasticity and strength. After being deformed by external force, it can recover its original shape by its own elasticity. It can repeatedly withstand the stress changes during the stretching and retraction of the conductive wire 21, and is not prone to fatigue fracture even after long-term use.

[0066] The portable power bank of this application embodiment has two symmetrically arranged through holes 322, and the two first limiting members 31 correspond one-to-one with the two through holes 322. This allows the first limiting members 31 to limit the first connecting part 22 on both sides symmetrically along the axis of the wire harness channel 321, so that the first connecting part 22 is subjected to balanced force, thereby maintaining the stability of the limiting, reducing the off-center load problem caused by unilateral limiting, and improving the reliability of the limiting. The extension part 313 extends from the fixing part to the corresponding through hole 322, and the fixing part is connected to the fixing seat 32. Therefore, the extension part 313 is connected to the fixing part and the fixing seat 32, which can improve the stability of the extension part 313 and make the limiting of the first connecting part 22 by the first limiting member 31 accurate.

[0067] Reference Figure 3 and Figure 4 In some possible embodiments of this application, the fixing part includes two first plates 311, which are disposed on the side wall of the fixing base 32 where a through hole 322 is provided. Along the axial direction of the wire harness channel 321, the extension part 313 extends from the first plates 311 to the through hole 322. The fixing part also includes a second plate 312, which is connected between the two first plates 311. The second plate 312 is provided with at least two limiting holes 3121. The fixing base 32 is provided with limiting posts 323 at the positions corresponding to the limiting holes 3121. The limiting posts 323 are inserted into the corresponding limiting holes 3121.

[0068] In this embodiment, there are two extensions 313, each corresponding to a first plate 311. The extensions 313 extend from one side of the first plate 311 toward the outside of the housing 1, and the trajectory of the extensions 313 is arc-shaped. Thus, the trajectories of the two extensions 313 pass through the through hole 322 and then extend to the outside of the through hole 322. In this way, part of the arc-shaped portion of the extension 313 can pass through the through hole 322, and the arc-shaped portion passing through the wire harness channel 321 can cooperate with the first connecting portion 22 to restrict the position of the first connecting portion 22.

[0069] In this embodiment, the second plate 312 fixes the two first plates 311 to the fixing base 32. The second plate 312 can have multiple limiting holes 3121, and the shape of the limiting holes 3121 can be adjusted according to the shape of the limiting posts 323 on the fixing base 32. The limiting holes 3121 can be rhomboid, circular, irregular, etc. When the second plate 312 has two limiting holes 3121, the two limiting holes 3121 can be symmetrically arranged along the axis of the wire harness through hole 322, thereby ensuring uniform force distribution on the second plate 312 and improving the stability between the second plate 312 and the fixing base 32.

[0070] In the portable power supply of this application embodiment, since the two first plates 311 are symmetrically arranged on the side wall of the fixing base 32, the extension 313 can be symmetrically arranged on the two side walls of the fixing base 32 where the through hole 322 is provided, thereby limiting the first connecting part 22 from two opposite directions, so that the force on the first connecting part 22 is balanced, and the displacement or instability of the limiting part due to stress concentration on one side is reduced.

[0071] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 In some possible embodiments of this application, a positioning structure 11 is provided inside the housing 1. The inner contour of the positioning structure 11 is adapted to the outer contour of the fixing seat 32. The fixing seat 32 is disposed inside the positioning structure 11, and the fixing seat 32 is detachably connected to the positioning structure 11.

[0072] In this embodiment of the application, the positioning structure 11 can define the installation position of the fixing seat 32 relative to the housing 1. Since the inner contour of the positioning structure 11 is adapted to the outer contour of the fixing seat 32, the positioning structure 11 can be nested on the outer periphery of the fixing seat 32, thereby defining the position of the fixing seat 32 in multiple directions and positioning the installation of the fixing seat 32.

[0073] It should be added that when the fixing seat 32 is installed in the positioning structure 11, the first limiting member 31 is also located in the positioning structure 11.

[0074] In this embodiment, the fixing seat 32 and the positioning structure 11 can be connected by a snap-fit ​​connection, a guide rail connection, or by bolts or rivets. For example, the positioning structure 11 has an elastic snap-fit ​​on its inner side, and the fixing seat 32 has a corresponding slot on its outer edge. During assembly, the fixing seat 32 is pressed to snap into the positioning structure 11, and during disassembly, the snap-fit ​​and the slot are separated.

[0075] In this embodiment of the portable power bank, the mounting base 32 and the positioning structure 11 are detachably connected, which facilitates the maintenance and replacement of the mounting base 32 and the first limiting member 31 provided on the mounting base 32. The positioning structure 11 can facilitate the installation and positioning of the mounting base 32 and can also limit the fixing member.

[0076] Reference Figure 3 , Figure 4 and Figure 5 In some possible embodiments of this application, the positioning structure 11 is connected to the fixing seat 32 by a fastener 34; the positioning structure 11 is provided with a first clearance recess 12 and a second clearance recess 13, the first clearance recess 12 is used to clearance the fastener 34, and the second clearance recess 13 is used to clearance the first limiting member 31.

[0077] In this embodiment, the first clearance recess 12 is used to avoid the fastener 34, and the shape of the first clearance recess 12 can be adjusted according to the shape of the fastener 34. The fastener 34 can be an internal hex socket head cap screw, a threaded mounting post pan head screw, etc.

[0078] In this embodiment, the second clearance recess 13 is used to avoid the first limiting member 31. The second plate 312 of the first limiting member 31 is inserted and engaged through the limiting post 323 on the fixing seat 32, thereby connecting the first limiting member 31 and the fixing seat 32. In order to facilitate the replacement and maintenance of the first limiting member 31, clearance can be made in the area where the second plate 312 and the fixing seat 32 are inserted and engaged, thus forming the second clearance recess 13. The shape of the second clearance recess 13 can be adjusted according to the shape of the second plate 312 or according to the arrangement of the limiting post 323 on the fixing seat 32. For example, the second clearance recess 13 is a U-shaped notch.

[0079] The portable power bank of this application embodiment, because the positioning structure 11 is provided with a first clearance recess 12 and a second clearance recess 13, can reduce interference between the fastener 34 and other areas of the positioning structure 11 during the process of connecting the fixing base 32 and the positioning structure 11 by the fastener 34, thereby reducing wear on the positioning structure 11. The second clearance recess 13 also facilitates operation of the limiting post 323 on the second plate 312 and the fixing base 32, thereby facilitating the maintenance and replacement of the first limiting member 31.

[0080] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7In some possible embodiments of this application, the first connecting part 22 is sleeved on the outer periphery of the conductive wire 21, and the outer periphery of the first connecting part 22 is provided with a limiting recess 221, which is adapted to the first limiting member 31; the inner periphery of the first connecting part 22 is provided with a friction structure, and the first connecting part 22 is fixed relative to the conductive wire 21 by the friction structure, or the first connecting part 22 moves along the axial direction of the conductive wire 21 under the action of external force to overcome the frictional force of the friction structure.

[0081] In this embodiment, the outer periphery of the first connecting part 22 has a limiting groove. When the first connecting structure is located in the wire harness channel 321, the limiting groove and the two through holes 322 on the fixing seat 32 correspond one-to-one. With this structure, the arc-shaped part of the extension 313 passing through the wire harness channel 321 can pass through the through hole 322 and engage with the limiting groove located in the wire harness channel 321, thereby limiting the first connecting part 22 from both sides.

[0082] In this embodiment, a friction structure is provided on the inner periphery of the first connecting part 22. The friction structure is provided on the inner periphery of the first connecting part 22. The friction structure is used to contact the outer periphery of the conductive wire 21 and generate friction between the friction structure and the conductive wire 21. The friction structure can be a rubber friction structure, a damping structure, etc. The friction structure can also be a special texture, such as a fishbone-shaped anti-slip texture, a wave-shaped anti-slip texture, etc.

[0083] In this embodiment, after the first connecting part 22 overcomes the frictional force of the friction structure under the action of external force, it can move along the axial direction of the wire, thereby adjusting the position of the first connecting part 22 on the conductive wire 21, thereby changing the length of the flexible section 211, so as to adjust the size and shape of the handle formed by the flexible section 211.

[0084] Reference Figure 1 , Figure 3 and Figure 6 In some possible embodiments of this application, at least two connecting portions include a second connecting portion 23, and the interface end of the conductive wire 21 forms the second connecting portion 23; the limiting structure 3 also includes a second limiting member 33, and the second connecting portion 23 and the second limiting member 33 are snap-fitted together; the first limiting member 31 and the second limiting member 33 are located on the same side or adjacent sides of the housing 1.

[0085] In this embodiment, the second connecting part 23 and the second limiting member 33 are engaged to fix the position of the interface end of the conductive wire 21 relative to the housing 1. At the same time, the first limiting member 31 limits the first connecting part 22 to fix the position of the first connecting part 22 relative to the housing 1. Thus, a flexible segment 211 is partially formed between the first connecting part 22 and the second connecting part 23. This flexible segment 211 can be used as a handle.

[0086] In this embodiment of the application, the second limiting member 33 can be a magnetic latch, a snap fastener, or other structure. For example, the second limiting structure 3 is formed with a slot, which can undergo small elastic deformation, and the interface end of the conductive wire 21 is snapped into the slot.

[0087] In this embodiment of the portable power bank, the first limiting member 31 and the second limiting member 33 are disposed on the same side of the housing 1, which can reduce the size of the flexible segment 211 between the first connecting part 22 and the second connecting part 23, save costs, and improve the compactness of the structure. The first limiting member 31 and the second limiting member 33 are disposed on adjacent sides of the housing 1, which can improve the stress on the housing 1 and reduce the deformation of the housing 1 during the process of using the flexible segment 211 for suspension or hand carrying.

[0088] Reference Figure 6 and Figure 8 In some possible embodiments of this application, the second limiting member 33 includes a connected limiting channel 4 and a wire passage opening 5, and the wire passage opening 5 and the limiting channel 4 penetrate the second limiting member 33 in the same direction; the inner wall of the limiting channel 4 forms a first limiting surface, which extends along the penetration direction of the limiting channel 4 and is used to abut against the second connecting portion 23; the radial dimension of the limiting channel 4 is less than or equal to the radial dimension of the second connecting portion 23; along the direction perpendicular to the penetration of the limiting channel 4, the size of the wire passage opening 5 is less than the minimum radial dimension of the second connecting portion 23 and greater than the maximum radial dimension of the conductive wire 21.

[0089] In this embodiment, the limiting channel 4 is a channel that penetrates the second limiting member 33. The conductive wire 21 can move within the limiting channel 4, and the limiting channel 4 can be used to accommodate the second connecting portion 23. The wire-passing opening 5 penetrates the second limiting member 33 along the extending direction of the limiting channel 4. It can also be understood that the wire-passing opening 5 is opened on the peripheral surface of the limiting channel 4, that is, an opening is made on the side of the limiting channel 4. The conductive wire 21 can enter or exit the limiting channel 4 laterally, so that the limiting channel 4 is connected to the outside in the peripheral direction, thereby allowing the conductive wire 21 to pass through the wire-passing opening 5 and enter the limiting channel 4.

[0090] In this embodiment, the inner cavity size of the limiting channel 4 is adapted so that the second connecting part 23 can move axially along the limiting channel 4. However, due to the radial dimension of the limiting channel 4, the second connecting part 23 cannot be directly dislodged from the limiting channel 4. Combined with the contact of the limiting surface, the second connecting part 23 is limited.

[0091] In this embodiment, since the radial dimension of the limiting channel 4 is less than or equal to the radial dimension of the second connecting part 23, the second connecting part 23 cannot pass through the limiting channel 4. When the second connecting part 23 is located inside the limiting channel 4, the limiting surface can abut against the second connecting part 23 to limit the second connecting part 23.

[0092] In this embodiment of the application, the wire-passing opening 5 allows entry into the limiting channel 4 from the outside of the limiting channel 4. The size of the wire-passing opening 5 in the direction perpendicular to the limiting channel 4 can determine the size of the structure that enters or exits from the wire-passing opening 5.

[0093] In this embodiment, if the size of the wire passage opening 5 in the direction perpendicular to the limiting channel 4 is smaller than the maximum radial size of the conductive wire 21, the conductive wire 21 can pass through or out of the wire passage opening 5; if the size of the wire passage opening 5 in the direction perpendicular to the limiting channel 4 is smaller than the minimum radial size of the second connecting part 23, the second connecting part 23 cannot pass through or out of the wire passage opening 5.

[0094] In this embodiment, the wire-passing opening 5 allows the conductive wire 21 to pass through. When it is necessary to limit the second connecting part 23, the conductive wire 21 is passed through the wire-passing opening 5 into the limiting channel 4. The conductive wire 21 is pulled along the through direction of the limiting channel 4, so that the second connecting part 23 enters the second limiting member 33 along the through direction of the limiting channel 4 and abuts against the limiting surface. The limiting surface limits the second connecting part 23. When it is necessary to use the second connecting part 23, the second connecting part 23 is moved along the through direction of the limiting channel 4 until the second connecting part 23 is no longer in contact with the limiting surface. Then the conductive wire 21 is passed out of the wire-passing opening 5. In this way, the second connecting part 23 can be taken out from the limiting channel 4 to connect to external electrical equipment.
