[0002] Portable power banks are widely used in people's daily lives due to their portability, efficiency, and practicality. However, some existing power banks lack a built-in charging cable, causing inconvenience, while others have lanyards on their casings for easy carrying or hanging, resulting in complex structures. Utility Model Content

[0003] This invention provides a portable power source with a charging cable that can also function as a lanyard, thereby improving ease of use and simplifying the structure.

[0004] This utility model provides a portable power bank, which includes a housing, a battery assembly, a data cable, and a connector. The housing forms a receiving cavity and has a wiring hole communicating with the receiving cavity and the outside. One end of the data cable is a connecting end, which extends into the receiving cavity through the wiring hole and is electrically connected to the battery assembly. The other end of the data cable is a movable end with a charging connector located outside the housing. The connector connects the connecting end of the data cable to the shell wall of the housing. A first connecting structure is formed on the outer side of the housing, and a second connecting structure is formed on the movable end. The second connecting structure is detachably connected to the first connecting structure.

[0005] Furthermore, the connector is disposed in the wiring hole, and the connecting end includes a wire connection portion, which is disposed in the wiring hole and engages with the connector.

[0006] Furthermore, the wall of the wiring hole is formed with a first groove, and the outer peripheral surface of the wire connection part is formed with a second groove that is opposite to the first groove. The first groove and the second groove surround each other to form a locking cavity, and the connector is locked into the locking cavity.

[0007] Furthermore, the wiring hole penetrates the shell wall of the housing along the first direction, the first groove has a first sidewall and a second sidewall opposite to each other along the first direction, a portion of the connector is located between the first sidewall and the second sidewall, the second groove has a third sidewall and a fourth sidewall opposite to each other along the first direction, and another portion of the connector is located between the third sidewall and the fourth sidewall.

[0008] Furthermore, the housing includes a bottom shell having a shell opening at one end along a second direction intersecting the first direction, and a shell cover covering the shell opening. The bottom shell and the shell cover form the receiving cavity. A first groove is formed in the bottom shell and extends along the second direction, and a first opening is formed at the end of the bottom shell facing the shell cover. A second groove extends along the second direction and a second opening is formed at the end of the wire connection facing the shell cover. The first opening and the second opening are matched to form an engagement opening for the connector to be engaged into the engagement cavity.

[0009] Furthermore, the cover closes the snap-in opening.

[0010] Furthermore, the housing includes a first shell wall and a second shell wall connected to each other, and a corner is formed at the connection between the first shell wall and the second shell wall. The wiring hole is provided on the first shell wall and is located on the first shell wall closer to the corner. The first connecting structure is provided on the second shell wall and is located on the second shell wall closer to the corner.

[0011] Furthermore, the first connecting structure includes a snap-fit ​​groove formed on the outer surface of the housing, and the second connecting structure includes a snap-fit ​​block capable of engaging with the snap-fit ​​groove.

The movable end of the data cable forms a second connecting structure, which is detachably connected to a first connecting structure formed on the outer side of the housing. Thus, when charging is needed, the second connecting structure of the movable end can be detached from the first connecting structure, allowing the movable end to move freely for convenient charging. When charging is not needed, the second connecting structure of the movable end is connected to the first connecting structure, forming a loop structure between the cable routing hole and the second connecting structure. This loop structure can be used as a lanyard. Therefore, the portable power bank provided by this invention allows for convenient charging when needed, improving usability, and when not charging, the data cable can also function as a lanyard, eliminating the need for a separate lanyard and simplifying the power bank's structure. In addition, the connector connects the data cable's connection end to the housing wall, reducing the possibility of the data cable moving outward relative to the cable routing hole when used as a lanyard, thereby improving the power bank's suspension stability and reducing the possibility of the data cable detaching from the battery assembly when used as a lanyard.

[0028] With the widespread use of mobile devices and the increasing frequency of people's use of mobile phones and other electronic devices, power banks have become an indispensable part of daily life. However, existing power banks need further improvement in terms of the ease of use of charging cables and the simplification of their structure.

[0029] Therefore, this application provides a portable power bank, which includes a housing, a battery assembly, a data cable, and a connector. The connecting end of the data cable extends into the receiving cavity through a cable routing hole and is electrically connected to the battery assembly. Simultaneously, the connecting end of the data cable is connected to the shell wall of the housing via the connector. The connecting end is configured to remain fixed relative to the housing, and the movable end of the data cable forms a second connecting structure, which is detachably connected to a first connecting structure formed on the outer side of the housing. This results in the portion of the data cable between the cable routing hole and the second connecting structure forming a loop structure, which can be used as a lanyard. Therefore, the portable power bank provided by this invention allows for convenient charging when needed, improving ease of use, and when not charging, the data cable can also function as a lanyard, eliminating the need for a separate lanyard and simplifying the power bank's structure.

[0030] Below, refer to Figures 1 to 7 Some embodiments of this application will be described in detail.

[0031] Figure 1 An exploded view of a portable power bank provided in some embodiments of this application; Figure 2 A cross-sectional view of a mobile power supply provided in some embodiments of this application; Figure 3 A schematic diagram of the structure of a power bank data cable provided in some embodiments of this application when used as a lanyard; Figure 4 A schematic diagram of the structure of the connection between the first shell wall and the second shell wall of the bottom shell of a power supply provided in some embodiments of this application; Figure 5 This is a partial structural diagram of the bottom shell of a power bank and the movable end of a data cable in a locked state, as provided in some embodiments of this application. Figure 6 This is a schematic diagram of the structure of the data cable and connector of the mobile power supply provided in some embodiments of this application; Figure 7 This is a partial structural diagram of the bottom shell and the movable end of the data cable provided in some embodiments of this application.

[0032] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; here, intersecting each other includes perpendicularly intersecting each other. For ease of understanding of the embodiments of this application, in... Figure 1 and Figure 7 In the illustrated embodiments, the first direction, the second direction, and the third direction are given as examples where they intersect each other perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as follows... Figure 1 and Figure 3 As shown by the arrows in the diagram, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction.

[0033] like Figures 1 to 7 As shown, this application provides a power bank, including a housing 1, a battery assembly 2, a data cable 4, and a connector 5. The housing 1 has a receiving cavity 11 and a wiring hole 12 communicating the receiving cavity 11 with the outside. The battery assembly 2 is disposed in the receiving cavity 11. One end of the data cable 4 is a connecting end 41, which extends into the receiving cavity 11 through the wiring hole 12 and is electrically connected to the battery assembly 2. The other end of the data cable 4 is a movable end 42 with a charging connector located outside the housing 1. The connector 5 connects the connecting end 41 of the data cable 4 to the shell wall of the housing 1. A first connecting structure 13 is formed on the outer side of the housing 1, and a second connecting structure 422 is formed on the movable end 42. The second connecting structure 422 is detachably connected to the first connecting structure 13.

[0034] The data cable 4 of the power bank provided in this embodiment extends into the receiving cavity 11 through the cable routing hole 12 and is electrically connected to the battery assembly 2. Simultaneously, the data cable 4's connection end 41 is connected to the shell wall of the housing 1 via a connector 5. The connection end 41 is configured to remain fixed relative to the housing 1. The movable end 42 of the data cable 4 forms a second connection structure 422, which is detachably connected to a first connection structure 13 formed on the outer side of the housing 1. Thus, when charging is required, the second connection structure 422 of the movable end 42 can be detached from the first connection structure 13, allowing the movable end 42 to move freely for convenient charging. When charging is not required, the second connection structure 422 of the movable end 42 is connected to the first connection structure 13, forming a loop structure between the cable routing hole 12 and the second connection structure 422. This loop structure can be used as a lanyard. Therefore, the power bank provided by this utility model can be conveniently charged when needed, improving ease of use. Furthermore, when not charging, the data cable 4 can also serve as a lanyard, eliminating the need for a separate lanyard and simplifying the power bank's structure. In addition, the connector 5 connects the connecting end 41 of the data cable 4 to the shell wall of the housing 1, reducing the possibility of the data cable 4 shifting outwards relative to the cable routing hole 12 when used as a lanyard, thereby improving the power bank's suspension stability and reducing the possibility of the data cable 4 detaching from the battery assembly 2 when used as a lanyard.

[0035] In some embodiments of this application, such as Figures 1 to 5 As shown, the connector 5 is disposed in the wiring hole 12, and the connecting end 41 includes a wire connecting part 411, which is disposed in the wiring hole 12 and engages with the connector 5.

[0036] The connector 5 is located in the cable hole 12 and engages with the cable connection part 411 of the data cable 4, which enhances the connection strength of the connection end 41 of the data cable 4, reduces the possibility that the data cable 4 may accidentally come out due to external force during use or storage, or may accidentally retract into the receiving cavity 11 due to external force during use, improves the stability of the electrical connection, extends the service life of the data cable 4, and simplifies the assembly process and improves production efficiency.

[0037] In some embodiments of this application, such as Figures 2 to 7 As shown, the wall of the wiring hole 12 has a first groove 121, and the outer peripheral surface of the wire connection part 411 has a second groove 4111 that is opposite to the first groove 121. The first groove 121 and the second groove 4111 surround each other to form a locking cavity 53, and the connector 5 is locked in the locking cavity 53.

[0038] The first groove 121 formed by the hole wall of the wiring hole 12 and the second groove 4111 formed by the outer peripheral surface of the wire connection part 411 form a locking cavity 53. The connector 5 is locked in the locking cavity 53, so that the connector 5 can constrain the relative position of the wire connection part 411 and the wiring hole 12, thereby realizing the fixed connection between the wire connection part 411 and the shell wall of the housing 1.

[0039] In some embodiments of this application, such as Figures 3 to 7 As shown, the wiring hole 12 penetrates the shell wall of the housing 1 along the first direction Z. The first groove 121 has a first sidewall 1211 and a second sidewall 1212 opposite to each other along the first direction Z. A portion of the connector 5 is located between the first sidewall 1211 and the second sidewall 1212. The second groove 4111 has a third sidewall 1213 and a fourth sidewall 1214 opposite to each other along the first direction Z. Another portion of the connector 5 is located between the third sidewall 1213 and the fourth sidewall 1214.

[0040] For example, the length between the first sidewall 1211 and the second sidewall 1212 is equal to the length between the third sidewall 1213 and the fourth sidewall 1214, and the first sidewall 1211 and the third sidewall 1213 are coplanar, as are the second sidewall 1212 and the fourth sidewall 1214. The surface formed by the connection of the first sidewall 1211 and the third sidewall 1213 is one inner wall of the engaging cavity 53, and the surface formed by the connection of the second sidewall 1212 and the fourth sidewall 1214 is another inner wall of the engaging cavity 53 opposite to the previous inner wall.

[0041] This configuration ensures that the connector 5 is firmly constrained in the first direction Z, reducing the loosening of the connector 5 due to vibration of the housing 1 or external impact, improving the suspension stability of the power bank, reducing the possibility of the wire connection part 411 extending or retracting into the receiving cavity 11 due to external force during use, improving the stability of the electrical connection, and extending the service life of the data cable 4.

[0042] In some embodiments of this application, such as Figures 1 to 7 As shown, the housing 1 includes a bottom shell 14 having a shell opening at one end along a second direction Y intersecting the first direction Z, and a shell cover 15 covering the shell opening. The bottom shell 14 and the shell cover 15 form a receiving cavity 11. A first groove 121 is formed in the bottom shell 14 and extends along the second direction Y, and a first opening 142 is formed at the end of the bottom shell 14 facing the shell cover 15. A second groove 4111 extends along the second direction Y and a second opening 143 is formed at the end of the line connection portion 411 facing the shell cover 15. The first opening 142 and the second opening 143 are matched to form an insertion opening 151 for the connector 5 to be inserted into the insertion cavity 53.

[0043] For example, the assembly process of the connector 5 and the housing 1 is as follows: the connecting end 41 of the data cable 4 enters the receiving cavity 11 through the cable hole 12, so that the cable connection part 411 reaches the cable hole 12. At this time, the second groove 4111 and the first groove 121 are relatively enclosed to form a locking cavity 53, and the first opening 142 of the first groove 121 and the second opening 143 of the second groove 4111 are relatively enclosed to form a locking opening 151. The connector 5 extends into the locking cavity 53 through the locking opening 151, thereby connecting the cable connection part 411 to the bottom shell 14, and then the bottom shell 14 is closed by the shell cover 15.

[0044] The first opening 142 and the second opening 143 form a snap-fit ​​opening 151, which facilitates the quick positioning and installation of the connector 5 during assembly, and the snap-fit ​​operation is convenient.

[0045] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, the wall of the wiring hole 12 has two first grooves 121 opposite each other along the third direction X, and the outer peripheral surface of the wire connection part 411 has two second grooves 4111 opposite each other along the third direction X. The third direction X, the second direction Y and the first direction Z intersect each other. The two first grooves 121 are respectively surrounded by the two second grooves 4111 to form two engaging cavities 53 arranged along the third direction X. The connector 5 includes a base 51 and two engaging parts 52 respectively connected to the opposite ends of the base 51 along the third direction X. The two engaging parts 52 are respectively engaged in the two engaging cavities 53.

[0046] Two engaging cavities 53 arranged along the third direction X distribute the two engaging portions 52 of the connector 5 on both sides of the wire connection portion 411. The symmetrical force-bearing structure can reduce the lateral torsional force on the data cable 4 during use, and reduce the deflection or loosening of the data cable 4. The two engaging cavities 53 can evenly distribute the tensile force to two independent force-bearing points, reduce local breakage caused by long-term stress on one side, and extend the overall life of the connector 5 and the cable.

[0047] In some embodiments of this application, such as Figure 6 and Figure 7 As shown, a third groove 4112 is also formed on the outer peripheral surface of the wire connection part 411, and the base 51 is engaged in the third groove 4112.

[0048] The first groove 121, the second groove 4111, and the third groove 4112 cause the base 51 and the engaging part 52 to engage with the third groove 4112 and the two engaging cavities 53 respectively. This causes at least three sides of the wire connection part 411 to be limited by the connector 5, improving the reliability of the connector 5 in connecting the data cable to the shell wall, improving the stability of the electrical connection, and extending the service life of the data cable 4.

[0049] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the cover 15 closes and snaps into the opening 151.

[0050] The cover 15 closes the snap-fit ​​opening 151, which can reduce the influence of the external environment on the connector 5, such as liquid seepage or foreign object interference, and maintain the appearance integrity and sealing of the housing 1. At the same time, the cover 15 hides the snap-fit ​​opening 151 after it is closed, so that the connector 5 cannot be dislodged from the snap-fit ​​cavity 53. This improves the reliability of the connector 5 in connecting the data cable 4 to the housing wall, improves the suspension stability of the power bank, improves the stability of the electrical connection, and extends the service life of the data cable 4.

[0051] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the housing 1 includes a first housing wall 17 and a second housing wall 18 connected to each other. A corner portion 16 is formed at the connection between the first housing wall 17 and the second housing wall 18. A wiring hole 12 is provided on the first housing wall 17 and is located on the first housing wall 17 closer to the corner portion 16. A first connecting structure 13 is provided on the second housing wall 18 and is located on the second housing wall 18 closer to the corner portion 16.

[0052] Both the cable routing hole 12 and the first connection structure 13 are located near the corner 16 of the housing 1, making full use of the edge space of the housing 1 so that the data cable 4 occupies little space after being stored, thus making it easy for users to hold and carry.

[0053] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the snap-fit ​​groove 131 includes a first fixing groove 1311 and a second fixing groove 1312 connected to one end of the first fixing groove 1311. The size of the first fixing groove 1311 in the second direction Y is smaller than that of the second fixing groove 1312, thereby forming a first limiting surface 132 at the connection between the two.

[0054] The latching block 421 includes a first latching part 4211 and a second latching part 4212. The size of the first latching part 4211 in the second direction Y is smaller than that of the second latching part 4212, thereby forming a second limiting surface 133 at the connection between the two. When the latching block 421 is latched into the latching groove 131, the first limiting surface 132 and the second limiting surface 133 are opposite to and abut against each other. Therefore, when the data cable 4 is used as a lanyard, the connection between the first connecting structure 13 and the second connecting structure 422 is highly reliable, thereby improving the suspension stability of the power bank.

[0055] The opening of the first fixing groove 1311 on the outer surface of the second shell wall 18 is smaller in the second direction Y than the opening of the first snap-fit ​​part 4211 in the second direction Y. Therefore, after the first snap-fit ​​part 4211 is inserted into the first fixing groove 1311, it forms a snap-fit ​​with the first fixing groove 1311. The first snap-fit ​​part 4211 is not easy to come out of the first fixing groove 1311, so that the first connecting structure 13 and the second connecting structure 422 are reliably connected.

[0056] In some embodiments of this application, such as Figure 1 As shown, the second fixing groove 1312 has a guide surface 1313 at one end away from the first fixing groove 1311. The guide surface 1313 guides the second connecting structure 422 to be inserted into and / or removed from the second fixing groove 1312.

[0057] The guide surface 1313 at the end of the second fixing groove 1312 away from the first fixing groove 1311 can reduce the frictional resistance when the second connecting structure 422 is inserted or removed, making the operation of the second connecting structure 422 in the second fixing groove 1312 smoother, reducing the effort required by the user, and improving ease of use.

[0058] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the housing 1 is also provided with a solar panel 6, which is fixedly connected to the housing 1 and electrically connected to the battery assembly 2. The solar panel 6 is exposed on the outside of the housing 1.

[0059] For example, solar panel 6 uses a polycrystalline silicon photovoltaic panel. Solar panel 6 includes a polycrystalline silicon photovoltaic panel, a surface protective layer, and wires. The polycrystalline silicon photovoltaic panel converts sunlight into direct current. The surface protective layer provides scratch and dust resistance. The wires connect the solar cells to the built-in circuitry of the power bank, transmitting power to battery module 2. The polycrystalline silicon photovoltaic panel, surface protective layer, and wires are not shown in the figure. The specific structure and working principle of solar panel 6 can be found in existing technologies and will not be described in detail here.

[0060] The solar panel 6 can convert light energy into electrical energy to replenish the battery module 2, significantly extending the power bank's battery life in outdoor or power-free environments, meeting emergency charging needs, and reducing energy consumption from frequent charging, which aligns with the concept of green environmental protection.

[0061] In some embodiments of this application, such as Figures 1 to 3 As shown, a receiving groove 19 is formed on the outer surface of the housing 1, and the solar panel 6 is received in the receiving groove 19 and is bonded to the groove wall of the receiving groove 19.

[0062] The solar panel 6 is housed in the receiving groove 19, which can reduce the size of the mobile power supply and reduce space occupation. The receiving groove 19 can also limit the solar panel 6, making the solar panel 6 more securely fixed to the housing 1.

[0063] For example, the power bank also includes a circuit board 3 and a display component (not shown in the figure), the display component being electrically connected to the circuit board 3 and disposed in the housing 1.

[0064] For example, the display component (not shown in the figure) includes an LED digital display screen and a lens. The LED digital display screen can display information such as battery level, date, and time. The lens is connected to the base shell, which protects the LED digital display screen from damage caused by external forces and maintains a good display effect. Neither the LED digital display screen nor the lens is shown in the figure.

[0065] In some embodiments of this application, the material of the base shell includes, but is not limited to, polycarbonate. The material of the lens includes, but is not limited to, polycarbonate, and the lens is semi-transparent black to ensure 90% transmittance and improve display effect.

[0066] For example, the circuit board 3 can be powered by either the battery assembly 2 or directly by the solar panel 6.

[0067] For example, the outer surface of the housing 1 is also provided with a power input / output interface (not shown in the figure), which can be, but is not limited to, a USB Type-C interface or a USB Type-A interface.

[0068] For example, the charging connector of data cable 4 can be, but is not limited to, a USB Type-C connector or a USB Type-A connector.

[0069] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
