Description

Technical Field

[0001] This application relates to the field of lanyard technology, and in particular to a lanyard structure, a lanyard data cable, and a power bank. Background Technology

[0002] As the industry has developed, some power banks that can use the charging cable as a lanyard have gradually appeared on the market. When charging is needed, the charging cable can be removed from the power bank; when not charging, the charging cable can be attached to the power bank as a lanyard.

[0003] However, existing lanyard structures typically employ snap-on, plug-in, or rotating storage methods. When the power bank is carried or hung, the connection between the power bank and the lanyard can easily loosen, leading to the power bank falling and being damaged. Utility Model Content

[0004] In view of this, this application provides a lanyard structure, a lanyard data cable, and a power bank to improve the technical problem of unstable lanyard connection in existing power banks, which easily leads to the power bank falling and being damaged.

[0005] One embodiment of this application provides a lanyard structure. The lanyard structure is configured to lock into a data cable. The data cable includes a cable body and a charging connector disposed at the end of the cable body. The lanyard structure includes a storage compartment and a locking assembly. The storage compartment has a connector configured to allow the charging connector to enter and exit the interior of the storage compartment. The locking assembly includes a rotating member and a resilient member. The rotating member is rotatably mounted in the storage compartment, and the resilient member is mounted between the storage compartment and the rotating member. The rotating member is configured to drive the charging connector to rotate to a position misaligned with the connector when the charging connector is inserted into the interior of the storage compartment, thereby preventing the charging connector from disengaging from the interior of the storage compartment. The resilient member is configured to press against the rotating member when the rotating member rotates relative to the storage compartment, thereby constraining the position of the rotating member relative to the storage compartment.

[0006] In the aforementioned lanyard structure, rotating the rotating component drives the charging connector to rotate until it is misaligned with the plug interface, thus enabling the charging cable to be stored. Simultaneously, the elastic component presses against the rotating component as it rotates relative to the storage compartment, constraining its position and providing control over its rotation angle. This reduces the risk of the storage compartment's stop failing due to the rotating component's angular rotation, causing the charging connector to detach from the storage compartment. Therefore, this design helps to improve the stability and safety of the power bank while ensuring its portability.

[0007] In some embodiments of this application, the elastic element is an arc-shaped spring. The arc-shaped spring is installed in the storage compartment, and the rotating component has a protrusion. The arc-shaped spring is configured to press the protrusion in a direction perpendicular to the rotation axis of the rotating component when the rotating component rotates relative to the storage compartment, so that the protrusion maintains frictional contact with the inner wall of the storage compartment, thereby applying a damping force during the rotation of the rotating component.

[0008] By utilizing the interplay between the arc-shaped spring and the protrusion, the rotation angle of the rotating component can be controlled, reducing the risk of angular backspin. When the rotating component rotates relative to the storage compartment under external force, the protrusion compresses the arc-shaped spring, causing it to elastically deform and generate elastic potential energy. The arc-shaped spring presses against the protrusion in a direction perpendicular to the rotation axis of the rotating component, maintaining frictional contact between the protrusion and the inner wall of the storage compartment to apply a damping force during the rotation of the component. When the external force acting on the rotating component is removed, the rotating component can be maintained at a specific position under the action of this damping force.

[0009] In some embodiments of this application, the storage compartment is provided with a groove, the protrusion is inserted into the groove, and is configured to slide within the groove. The arc-shaped spring is at least partially located within the groove and occupies part of the movement path of the protrusion.

[0010] The groove design guides the rotating component, reducing the risk of misalignment and improving the stability and ease of installation of the hanging rope structure. When the rotating component rotates relative to the storage compartment under external force, the protrusion slides within the groove. Because the arc-shaped spring occupies the movement path of the protrusion, the protrusion compresses the arc-shaped spring during rotation, causing it to elastically deform and generate elastic potential energy. The arc-shaped spring acts on the protrusion in a direction perpendicular to the rotation axis of the rotating component.

[0011] In some embodiments of this application, the arc-shaped spring is provided with a first groove and a second groove, which are spaced apart along the rotation direction of the rotating member. The rotating member has a first position and a second position and is configured to be switchable to the first position or the second position. When the rotating member is in the first position, the protrusion engages in the first groove, and the charging connector is configured to be able to enter and exit the interior of the storage compartment. When the rotating member is in the second position, the protrusion engages in the second groove, and the charging connector is configured to be offset from the plug interface.

[0012] Because the curved spring has a first groove and a second groove, when the protrusion moves to the first position or the second position, the protrusion can be engaged in the first groove or the second groove to form tactile feedback (such as a "click" positioning), which helps to improve the user's operating experience.

[0013] In some embodiments of this application, the arc-shaped spring includes a first fixed section, a second fixed section, and a free section. The first fixed section and the second fixed section are disposed at both ends of the free section, and both the first fixed section and the second fixed section are connected to the storage compartment. The free section is close to the inner wall of the storage compartment along a direction perpendicular to the rotation axis of the rotating component. The first fixed section and the free section together form a first groove, and the second fixed section and the free section together form a second groove.

[0014] As the protrusion moves between the first and second positions, the elastic force generated in the free segment undergoes a process of decreasing magnitude. In other words, the damping force experienced by the rotating component during rotation also undergoes a process of decreasing magnitude. Users can judge whether the rotating component has reached its designated position, i.e., whether the charging connector has been locked or unlocked, based on the change in feel (specifically, the change in the magnitude of the damping force on the hand). This improves the operational feel of the lanyard structure and ultimately enhances the user experience.

[0015] In some embodiments of this application, the elastic element is a spring, with one end of the spring abutting and fixed to the storage compartment, and the other end pressing against the rotating element.

[0016] By using springs to directly constrain the position of the rotating component, not only is the hanging rope structure simplified, but its flexibility is also improved. The springs can constrain the rotating component's position regardless of its rotation. When the rotating component rotates relative to the storage compartment, the springs always press against it in a direction perpendicular to its rotation axis, maintaining frictional contact between the rotating component and the inner wall of the storage compartment to apply damping force during rotation. When the external force acting on the rotating component is removed, it can maintain a specific position under the action of the damping force.

[0017] In some embodiments of this application, the locking assembly further includes a friction plate mounted on the end of the spring facing the rotating component. Adding a friction plate (such as a polyurethane pad) to the end of the spring helps improve the uniformity of the damping force exerted by the spring on the rotating component, reducing the risk of component damage due to excessive concentration of damping force.

[0018] In some embodiments of this application, the rotating component includes a rotating body and a driving part. The rotating body is rotatably mounted in the storage compartment and has a protrusion. The driving part is mounted on the rotating body and extends into the interior of the storage compartment along the insertion direction of the charging connector. The driving part is configured to drive the charging connector to rotate when the rotating component rotates relative to the storage compartment.

[0019] When the rotating part rotates relative to the storage compartment under the action of external force, the drive unit can drive the charging connector to rotate relative to the storage compartment, so as to realize the misalignment of the charging connector and the plug interface, that is, to lock the charging connector.

[0020] In some embodiments of this application, the drive unit is provided with a limiting groove, which is configured to engage with the charging connector when the charging connector is inserted into the storage compartment. The limiting groove helps reduce the risk of the charging connector falling off or wobbling when rotating relative to the storage compartment, thus improving the stability of the lanyard structure.

[0021] In some embodiments of this application, the storage compartment is provided with a mounting groove, and the bottom wall of the mounting groove has a through hole that communicates with the interior of the storage compartment. The rotating main body is rotatably mounted in the mounting groove, and the driving part passes through the through hole and extends into the interior of the storage compartment. By providing a mounting groove and inserting the rotating part into the mounting groove, the overall volume of the hanging rope structure is reduced, making it easier for users to carry and store.

[0022] In some embodiments of this application, the rotating component further includes a buckle disposed on the rotating body, the buckle having a through hole and being movably engaged with the storage compartment. By employing a buckle structure, the maintenance or replacement of the hanging rope structure is facilitated; technicians only need to disconnect the buckle from the storage compartment to disassemble the rotating component without damaging the storage compartment.

[0023] One embodiment of this application provides a lanyard data cable. The lanyard data cable includes a data cable and a lanyard structure as described in any of the above embodiments. The data cable includes a cable body and a charging connector disposed at the end of the cable body, the charging connector being configured to enter and exit the interior of a storage compartment.

[0024] By adopting the aforementioned lanyard structure, the portability of the lanyard data cable can be ensured while improving its stability and safety, reducing the risk of the power bank falling off and being damaged due to unstable lanyard connection.

[0025] One embodiment of this application provides a portable power bank. The portable power bank includes a battery assembly and a lanyard structure as described in any of the above embodiments, the lanyard structure being detachably mounted to the battery assembly.

[0026] By employing the aforementioned lanyard structure in the power bank, the portability of the power bank can be ensured while improving its stability and safety, reducing the risk of the power bank falling off and being damaged due to unstable lanyard connection. Attached Figure Description

[0042] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0045] As the industry has developed, some power banks that can use the charging cable as a lanyard have gradually appeared on the market. When charging is needed, the charging cable can be removed from the power bank; when not charging, the charging cable can be attached to the power bank as a lanyard.

[0046] However, existing lanyard structures typically employ snap-on, plug-in, or rotating storage methods. When the power bank is carried or hung, the connection between the power bank and the lanyard can easily loosen, leading to the power bank falling and being damaged.

[0047] One embodiment of this application provides a lanyard structure. The lanyard structure is configured to lock into a data cable. The data cable includes a cable body and a charging connector disposed at the end of the cable body. The lanyard structure includes a storage compartment and a locking assembly. The storage compartment has a connector configured to allow the charging connector to enter and exit the interior of the storage compartment. The locking assembly includes a rotating member and a resilient member. The rotating member is rotatably mounted in the storage compartment, and the resilient member is mounted between the storage compartment and the rotating member. The rotating member is configured to drive the charging connector to rotate to a position misaligned with the connector when the charging connector is inserted into the interior of the storage compartment, thereby preventing the charging connector from disengaging from the interior of the storage compartment. The resilient member is configured to press against the rotating member when the rotating member rotates relative to the storage compartment, thereby constraining the position of the rotating member relative to the storage compartment.

[0048] In the aforementioned lanyard structure, rotating the rotating component drives the charging connector to rotate until it is misaligned with the plug interface, thus enabling the charging cable to be stored. Simultaneously, the elastic component presses against the rotating component as it rotates relative to the storage compartment, constraining its position and providing control over its rotation angle. This reduces the risk of the storage compartment's stop failing due to the rotating component's angular rotation, causing the charging connector to detach from the storage compartment. Therefore, this design helps to improve the stability and safety of the power bank while ensuring its portability.

[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] Please refer to the following: Figures 1 to 3 One embodiment of this application provides a lanyard data cable 100. The lanyard data cable 100 includes a data cable 10 and a lanyard structure 20, which is locked to the data cable 10.

[0051] By locking the lanyard structure 20 and the data cable 10 together, the charging function and the lanyard function of the data cable 10 can be combined into one, which helps to improve the user experience.

[0052] For example, when the data cable 10 is locked in place with the lanyard structure 20, the data cable 10 can act as a lanyard to be suspended from a target object (specifically, a wrist, hook, or other support). When the locking engagement between the lanyard structure 20 and the data cable 10 is released, one end of the data cable 10 is connected to a power source (not shown), and the other end is connected to a device to be charged (not shown), thereby charging the device. The device to be charged can be an electronic product such as a mobile phone or iPad.

[0053] In some embodiments, the data cable 10 includes a cable body 11 and a charging connector 12 disposed at one end of the cable body 11. The charging connector 12 can be a Lightning interface, a USB-C interface, etc. The cable body 11 is configured to act as a lanyard when the data cable 10 is locked in engagement with the lanyard structure 20. The charging connector 12 is configured to connect to a power source or a device to be charged when the lanyard structure 20 is released from the locking engagement with the data cable 10.

[0054] In some embodiments, the lanyard structure 20 is mounted on the power bank 200 (such as a portable charger) to facilitate user use and carrying of the power bank 200. Exemplarily, the lanyard structure 20 is suspended from the power bank 200 by a thin line (not shown). Specifically, the power bank 200 has a hanging hole (not shown) on its edge, one end of the thin line passes through the hanging hole, and the other end of the thin line passes through the lanyard structure.

[0055] In other embodiments, the thin thread may be omitted, and the hanging rope structure 20 may be directly attached to the hanging hole of the power bank 200 through the snap ring. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0056] In some embodiments, the line 11 is configured to be flexibly deformable.

[0057] In some embodiments, there are two charging connectors 12, one of which is connected to a power source and the other is connected to an electronic device.

[0058] In other embodiments, the number of charging connectors 12 may also be 3, 4, or other numbers. This application does not limit this number, and those skilled in the art can choose according to the actual situation.

[0059] Please refer to the following: Figures 3 to 5 In some embodiments, the lanyard structure 20 includes a storage compartment 21 and a locking assembly 22. The storage compartment 21 is provided with a connector 211 configured to allow the charging connector 12 to enter and exit the interior of the storage compartment 21. The locking assembly 22 includes a rotatable member 221 rotatably mounted on the storage compartment 21.

[0060] The rotating component 221 is configured to drive the charging connector 12 to rotate to a position that is misaligned with the plug interface 211 when the charging connector 12 is inserted into the storage compartment 21, so as to prevent the charging connector 12 from disengaging from the storage compartment 21, thereby realizing the storage of the data cable 10.

[0061] It is worth noting that, as mentioned above, the charging connector 12 is inserted into the interior of the storage compartment 21, specifically meaning that the charging connector 12 is completely housed inside the storage compartment 21. The charging connector 12 is misaligned with the insertion interface 211, specifically meaning that at the insertion interface 211, the projection of the storage compartment 21 along the insertion direction overlaps with the charging connector 12.

[0062] Understandably, when the data cable 10 is not in use, the charging connector 12 of the data cable 10 is inserted into the storage compartment 21 along the plug interface 211. The rotating component 221 rotates and drives the charging connector 12 to rotate synchronously until the charging connector 12 is misaligned with the plug interface 211, thereby achieving storage and locking of the data cable 10.

[0063] When the data cable 10 is needed, simply rotate the rotating part 221 in the opposite direction to return it to its initial position and remove the charging connector 12 from the inside of the storage compartment 21 to release the lock on the data cable 10. It should be noted that the initial position specifically refers to the position of the rotating part 221 when the projection of the storage compartment 21 at the plug interface 211 along the plugging direction does not overlap with the charging connector 12.

[0064] Please refer to the following: Figure 3 , Figures 6 to 7 In some embodiments, the locking component 22 further includes an elastic element 222 fitted between the storage compartment 21 and the rotating component 221. The elastic element 222 is configured to press the rotating component 221 against the storage compartment 21 as the rotating component 221 rotates relative to the storage compartment 21, thereby constraining the position of the rotating component 221 relative to the storage compartment 21.

[0065] By setting the elastic element 222, the rotation angle of the rotating element 221 can be controlled, reducing the risk that the storage compartment 21 will fail to stop due to the rotation of the rotating element 221 and the charging connector 12 will detach from the storage compartment 21.

[0066] The lanyard structure 20 provided in this application, through the cooperation of the rotating part 221 and the elastic part 222, can improve the stability and safety of the lanyard data cable 100 while ensuring its portability, and reduce the risk of the product falling off and being damaged due to unstable lanyard connection.

[0067] Please refer to the following: Figures 7 to 9 In some embodiments, the elastic element 222 is an arc-shaped spring sheet. The arc-shaped spring sheet 222 is installed in the storage compartment 21. The rotating element 221 has a protrusion 2211. The arc-shaped spring sheet 222 is configured to press the protrusion 2211 in a direction perpendicular to the rotation axis of the rotating element 221 when the rotating element 221 rotates relative to the storage compartment 21, so that the protrusion 2211 maintains frictional contact with the inner wall of the storage compartment 21, so as to apply a damping force during the rotation of the rotating element 221.

[0068] Understandably, when the rotating component 221 rotates relative to the storage compartment 21 under the action of an external force, the protrusion 2211 will compress the arc-shaped spring sheet 222, causing the arc-shaped spring sheet 222 to undergo elastic deformation and generate elastic potential energy. Under the action of elastic potential energy, the arc-shaped spring sheet 222 presses against the protrusion 2211 in a direction perpendicular to the rotation axis of the rotating component 221, so that the protrusion 2211 maintains frictional contact with the inner wall of the storage compartment 21, thereby applying a damping force during the rotation of the rotating component 221.

[0069] When the external force acting on the rotating member 221 is removed, the rotating member 221 can be maintained at a specific position under the action of the damping force. The specific position specifically refers to the position of the rotating member 221 when the charging connector 12 and the plug interface 211 interfere with each other, and the position of the rotating member 221 when the charging connector 12 and the plug interface 211 do not interfere with each other (i.e., the initial position mentioned above).

[0070] By cooperating with the arc-shaped spring piece 222 and the protrusion 2211, the rotation angle of the rotating part 221 can be controlled, reducing the risk that the stop of the storage compartment 21 will fail due to the angular rotation of the rotating part 221, and the charging connector 12 will detach from the storage compartment 21.

[0071] Please refer to the following: Figures 7 to 9 In some embodiments, the storage compartment 21 is provided with a groove 212, and the protrusion 2211 is inserted into the groove 212 and configured to slide within the groove 212. The arc-shaped spring piece 222 is at least partially located within the groove 212 and occupies part of the movement path of the protrusion 2211. The groove 212 provides guidance for the rotating member 221, which helps reduce the risk of the rotating member 221 deviating and improves the stability and installability of the hanging rope structure 20.

[0072] Understandably, when the rotating component 221 rotates relative to the storage compartment 21 under the action of an external force, the protrusion 2211 slides within the groove 212. Since the arc-shaped spring piece 222 occupies the movement path of the protrusion 2211, the protrusion 2211 will compress the arc-shaped spring piece 222 during rotation, causing the arc-shaped spring piece 222 to undergo elastic deformation and generate elastic potential energy.

[0073] Under the action of elastic potential energy, the arc-shaped spring 222 acts on the protrusion 2211 in a direction perpendicular to the rotation axis of the rotating member 221, so that the protrusion 2211 maintains frictional contact with the inner wall of the storage compartment 21, so as to apply damping force during the rotation of the rotating member 221.

[0074] For example, a groove 212 is provided on one end face of the storage compartment 21 away from the insertion interface 211, and the groove 212 is arc-shaped. The protrusion 2211 is slidably inserted into the groove 212. The arc-shaped spring piece 222 is completely installed in the groove 212, and part of the arc-shaped spring piece 222 occupies part of the movement path of the protrusion 2211.

[0075] By placing all the arc-shaped spring pieces 222 within the groove 212, the overall structure of the hanging rope 20 can be made more compact, which helps to reduce the space occupied by the hanging rope structure 20 and facilitates storage.

[0076] In other embodiments, the arc-shaped spring piece 222 may also be partially located in the groove 212, and the portion located in the groove 212 may occupy part of the movement path of the protrusion 2211. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0077] Please refer to the following: Figures 7 to 9 In some embodiments, the arc-shaped spring piece 222 is provided with a first groove 2221 and a second groove 2222, which are spaced apart along the rotation direction of the rotating member 221. The rotating member 221 has a first position and a second position and is configured to be able to switch to the first position or the second position.

[0078] When the rotating member 221 is in the first position, the protrusion 2211 engages with the first groove 2221, and the charging connector 12 is configured to enter and exit the interior of the storage compartment 21. When the rotating member 221 is in the second position, the protrusion 2211 engages with the second groove 2222, and the charging connector 12 is configured to be offset from the plug interface 211.

[0079] Understandably, when the protrusion 2211 moves to the first position or the second position, the protrusion 2211 can engage in the first groove 2221 or the second groove 2222 to form tactile feedback (such as a "click" positioning), which is beneficial to improving the user's operating experience.

[0080] Please see Figure 8 In some embodiments, the arc-shaped spring 222 includes a first fixed segment 2223, a second fixed segment 2224, and a free segment 2225. The first fixed segment 2223 and the second fixed segment 2224 are disposed at both ends of the free segment 2225, and both the first fixed segment 2223 and the second fixed segment 2224 are connected to the storage compartment 21.

[0081] The free segment 2225 approaches the inner wall of the storage compartment 21 in a direction perpendicular to the rotation axis of the rotating member 221. The first fixed segment 2223 and the free segment 2225 together form the first groove 2221, and the second fixed segment 2224 and the free segment 2225 together form the second groove 2222.

[0082] When the protrusion 2211 moves between the first position and the second position, the elastic force generated by the free segment 2225 will change from large to small. That is to say, the damping force experienced by the rotating member 221 during rotation will change from large to small.

[0083] Users can judge whether the rotating part 221 has rotated to the correct position, that is, whether the charging connector 12 has been locked or unlocked, by the change in feel (specifically the change in the magnitude of the damping force on the hand). This helps to improve the operation feel of the lanyard structure 20 and thus enhance the user experience.

[0084] In some embodiments, the elastic element 222 is a spring, with one end of the spring abutting and fixed to the storage compartment 21, and the other end pressing against the rotating element 221. By using a spring to directly constrain the position of the rotating element 221, it is not only beneficial to simplify the hanging rope structure 20, but also to improve the flexibility of the hanging rope structure 20. The spring can constrain the position of the rotating element 221 when it is rotated to any position.

[0085] Understandably, when the rotating component 221 rotates relative to the storage compartment 21, the spring always presses the rotating component 221 in a direction perpendicular to the rotation axis of the rotating component 221, so that the rotating component 221 maintains frictional contact with the inner wall of the storage compartment 21, thereby applying a damping force during the rotation of the rotating component 221. When the external force acting on the rotating component 221 is removed, the rotating component 221 can be maintained at a specific position under the action of the damping force.

[0086] In some embodiments, the locking assembly 22 further includes a friction pad (not shown) mounted on the end of the spring facing the rotating member 221. By adding a friction pad (such as a polyurethane pad) to the end of the spring, it is beneficial to improve the uniformity of the damping force of the spring on the rotating member 221 and reduce the risk of component damage due to excessive concentration of damping force.

[0087] Please refer to the following: Figure 10 and Figure 11 In some embodiments, the rotating component 221 includes a rotating body 2212 and a driving part 2213. The rotating body 2212 is rotatably mounted on the storage compartment 21, and the rotating body 2212 is provided with a protrusion 2211.

[0088] The drive unit 2213 is mounted on the rotating body 2212 and extends into the storage compartment 21 along the insertion direction of the charging connector 12. The drive unit 2213 is configured to drive the charging connector 12 to rotate when the rotating member 221 rotates relative to the storage compartment 21.

[0089] Understandably, when the rotating part 221 rotates relative to the storage compartment 21 under the action of external force, the rotating body 2212 drives the driving part 2213 to rotate, and the driving part 2213 drives the charging connector 12 to rotate relative to the storage compartment 21 until the charging connector 12 is misaligned with the plug interface 211, that is, the charging connector 12 is locked.

[0090] In some embodiments, the drive unit 2213 is provided with a limiting groove 2214, which is configured to engage with the charging connector 12 when it is inserted into the storage compartment 21. The limiting groove 2214 helps to reduce the risk of the charging connector 12 falling off or shaking when it rotates relative to the storage compartment 21, thereby improving the stability of the lanyard structure 20.

[0091] Please refer to the following: Figure 6 , Figures 9 to 10 In some embodiments, the storage compartment 21 is provided with a mounting groove 213, and the bottom wall of the mounting groove 213 is provided with a through hole 214. The through hole 214 is connected to the interior of the storage compartment 21. The rotating body 2212 is rotatably mounted on the mounting groove 213, and the driving part 2213 passes through the through hole 214 and extends into the interior of the storage compartment 21.

[0092] By setting the mounting slot 213 and inserting the rotating part 221 into the mounting slot 213, it is easier to reduce the overall volume of the hanging rope structure 20, making it easier for users to carry and store.

[0093] In some embodiments, the rotating component 221 further includes a buckle 2215 disposed on the rotating body 2212. The buckle 2215 passes through the through hole 214 and is movably engaged with the storage compartment 21. By adopting the buckle 2215 structure, it is convenient for the maintenance or replacement of the hanging rope structure 20. Technicians only need to disconnect the connection between the buckle 2215 and the storage compartment 21 to disassemble the rotating component 221 without damaging the storage compartment 21.

[0094] In other embodiments, the rotating component 221 may also adopt other structures to be movably connected to the storage compartment 21. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0095] Please see Figure 12 One embodiment of this application provides a portable power bank 200. The portable power bank 200 can be a power bank, a handheld energy storage device, etc. This application does not limit the scope of the application; those skilled in the art can choose according to the actual situation.

[0096] In some embodiments, the power bank 200 includes a battery assembly 210 and the aforementioned lanyard structure 20, which is detachably mounted to the battery assembly 210. When the power bank 200 is not in use, the user inserts the charging connector 12 into the storage compartment 21 along the plug interface 211 and rotates the rotating member 221 against the elastic force of the elastic member 222.

[0097] The rotating component 221 drives the charging connector 12 to rotate until the charging connector 12 is misaligned with the plug interface 211. At this time, the elastic component 222 can constrain the position of the rotating component 221 relative to the storage compartment 21, and the data cable 10 can act as a hanging rope to suspend it on the target object.

[0098] When the power bank 200 is needed, the user simply overcomes the elastic force of the elastic element 222, reverses the rotation element 221 to return it to its initial position, and removes the charging connector 12 from the storage compartment 21 to release the data restriction lock. One end of the data cable 10 is connected to the power source, and the other end is connected to the device to be charged to enable charging of the device.

[0099] The power bank 200 provided in this application, by employing the aforementioned lanyard structure 20, not only enables the storage of the charging cable but also provides control over the rotation angle of the rotating component 221. This reduces the risk of the charging connector 12 detaching from the storage compartment 21 due to the rotating component 221 angularly rotating. Therefore, while ensuring the portability of the power bank 200, its stability and safety are improved, reducing the risk of the power bank 200 falling off and being damaged due to unstable lanyard connection.

[0100] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
