Description

Technical Field

[0001] This utility model relates to the field of electronic device technology, and in particular to an electronic device accessory with a retractable data cable. Background Technology

[0002] Electronic devices are widely used in people's daily lives. Currently, the data cables of electronic devices are generally located outside the device's casing, and their length is fixed. This can lead to the data cables becoming twisted, bent, tangled, or even broken. This not only hinders the neat and orderly storage of electronic devices but can also cause damage. Utility Model Content

[0003] This utility model provides an electronic device accessory with a retractable and lockable data cable, which enables convenient storage of electronic devices, makes the data cable less prone to damage, and thus improves the durability of electronic devices.

[0004] This utility model provides an electronic device accessory, including: a housing; a data cable, one end of which is disposed inside the housing and the other end of which is a telescopic end with a connector; and a telescopic locking structure exposed outside the housing, the telescopic locking structure having an unlocked state and a locked state. In the unlocked state, the telescopic end of the data cable can extend out of the housing or retract into the housing, and in the locked state, the data cable is locked.

[0005] Furthermore, the telescopic locking structure includes: a rotating wheel rotatably disposed within the housing about its own central axis, the data cable being wound around the rotating wheel; and a locking switch disposed on the housing, the locking switch being configured to reciprocate between an unlocked position and a locked position relative to the housing. When the locking switch is in the unlocked position, the telescopic end of the data cable can extend or retract relative to the housing in conjunction with the rotation of the rotating wheel; when the locking switch is in the locked position, the rotating wheel is locked.

[0006] Furthermore, the rotating wheel has a first fixing part, and the locking switch has a second fixing part. When the locking switch is in the unlocked position, the first fixing part and the second fixing part are separated; when the locking switch is in the locked position, the first fixing part and the second fixing part are locked together.

[0007] Furthermore, the first fixing part is a first sawtooth formed on the outer circumference of the wheel, and the second fixing part is a second sawtooth. The first sawtooth and the second sawtooth can mesh with each other or separate from each other.

[0008] Furthermore, the wheel includes a winding portion and two limiting portions. Each end of the winding portion along its axial direction is connected to one of the limiting portions. A winding groove is formed between the surfaces of the two limiting portions facing each other and the outer peripheral surface of the winding portion. The data cable is wound around the winding groove.

[0009] Furthermore, the outer periphery of both limiting portions is formed with the first sawtooth, and the locking switch also includes two locking plates, both of which are formed with the second sawtooth. When the locking switch is in the locked position, the first sawtooth of the two limiting portions respectively engages with the second sawtooth of the two locking plates.

[0010] Furthermore, the locking switch also includes a base portion, one end of each of the two locking plates is connected to the base portion, and the end of the locking plate away from the base portion forms the second serration.

[0011] Furthermore, the housing has a through groove, the base portion is located outside the housing, and the second serration of the locking plate extends into the housing through the through groove.

[0012] Furthermore, the locking switch also includes a connecting structure, which is connected to the base portion and located between the two locking plates. The locking switch is movably connected to the housing along a first direction via the connecting structure.

[0013] Furthermore, one end of the connecting structure is connected to the base portion, and the other end forms a limiting head. The housing has a sliding groove extending along the first direction. The limiting head of the connecting structure passes through the sliding groove and is limited within the housing. The connecting structure can reciprocate relative to the sliding groove along the first direction, so that the locking switch reciprocates between the unlocked position and the locked position.

[0014] Furthermore, the surface of the base portion facing away from the locking plate is formed with at least one groove structure and / or protrusion structure.

[0015] Furthermore, the locking switch reciprocates between the unlocked position and the locked position along a first direction, the first direction being tangent to the rotation direction of the rotating wheel.

[0016] Furthermore, the telescopic locking structure also includes an elastic reset member, which is connected between the housing and the rotating wheel. The elastic reset member can apply an elastic reset force to the rotating wheel, and the direction of the elastic reset force is opposite to the winding direction of the data cable on the rotating wheel.

[0017] This utility model provides an electronic device accessory, including a housing, a data cable, and a telescopic locking structure. The telescopic locking structure has two modes: an unlocked state and a locked state. In the unlocked state, the data cable can extend or retract from the housing, thereby adjusting the length of the data cable outside the housing. In the locked state, the data cable is locked and cannot be retracted or extended from the housing. Therefore, the electronic device accessory provided by this utility model allows for adjustment of the length of the data cable outside the housing, without being limited by a fixed length, providing high flexibility and enabling the electronic device accessory to adapt to the needs of different usage scenarios. Furthermore, due to the telescopic nature of the data cable, it is less prone to twisting, bending, or knotting during use, thus reducing damage caused by twisting, bending, or knotting and extending the service life of the electronic device accessory. Moreover, when not in use, the data cable can be retracted to its shortest state, not only reducing damage to the data cable but also facilitating convenient storage of the electronic device accessory.

[0028] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0029] 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 to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0032] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0033] With the widespread adoption of mobile devices and people's increasing reliance on smartphones and other electronic devices, electronic devices have become indispensable in daily life. Because the data cables of existing electronic device accessories are exposed outside the casing, there is a growing demand for improved durability by protecting the data cables from damage, as well as for more convenient use of these accessories.

[0034] Therefore, this application provides an electronic device accessory, including a housing, a data cable, and a telescopic locking structure. The telescopic locking structure allows the data cable to extend out of the housing to connect to an external device when needed, and to retract as far as possible into the housing when not in use. The telescopic locking structure has two modes: an unlocked state and a locked state. In the unlocked state, the data cable can extend or retract into the housing of the electronic device accessory, while in the locked state, the data cable can be fixed at any selectable length, without actively retracting or extending further out of the housing. In the unlocked state, the data cable can extend or retract as needed, without being limited by a fixed length, providing high flexibility and allowing the electronic device accessory to adapt to different usage scenarios. In the locked state, the data cable can be fixed at any selectable length. When not in use, the data cable is stored in the housing, reducing damage caused by twisting, bending, or knotting, thereby improving the lifespan of the electronic device accessory. The controllability of the data cable length allows for flexible adjustments as needed during use, preventing damage from excessive length or charging inconvenience from excessive length.

[0035] Below, refer to Figures 1 to 8 Some embodiments of this application will be described in detail.

[0037] It should be noted that electronic device accessories can refer to auxiliary parts or components used to support, expand, enhance, or maintain the functions of electronic devices. These include, but are not limited to, any one of power banks, docking stations, stands, power strips, and retractable data cables. This application uses a power bank as an example to illustrate the electronic device accessories of this application.

[0038] like Figure 1 and Figure 2 As shown, this application provides an electronic device accessory, including a housing 1, a data cable 3, and a telescopic locking structure 4. One end of the data cable 3 is disposed inside the housing 1, and the other end is a telescopic end 31 with a connector. The telescopic locking structure 4 is exposed outside the housing 1 and has an unlocked state and a locked state. In the unlocked state, the telescopic end 31 of the data cable 3 can extend out of the housing 1 or retract into the housing 1. In the locked state, the data cable 3 is locked.

[0039] "Data cable 3 is locked" means that the extension and retraction movement of data cable 3 is locked. That is, the extension and retraction end 31 of data cable 3 cannot extend or retract. In other words, the extension and retraction end 31 of data cable 3 can neither extend nor retract, thereby fixing the length of the part of the extension and retraction end 31 outside the housing 1.

[0040] "The telescopic locking structure 4 is exposed outside the housing 1" means that at least part of the telescopic locking structure 4 is exposed outside the housing 1, that is, at least part of the telescopic locking structure 4 can be seen outside the housing 1.

[0041] The electronic device accessory provided in this application has a telescopic locking structure 4 with two modes: an unlocked state and a locked state. In the unlocked state, the data cable 3 can extend or retract, thereby adjusting the length of the data cable 3 outside the housing 1. In the locked state, the data cable 3 is locked and cannot be retracted or extended. Therefore, when it is necessary to adjust the length of the data cable 3 outside the housing 1, the telescopic locking structure 4 is switched to the unlocked state, and then the data cable 3 is extended or retracted. After adjusting to the appropriate length, the telescopic locking structure 4 is switched to the locked state. At this time, the data cable 3 cannot extend or retract, and the length of the data cable 3 outside the housing 1 is fixed. Therefore, the electronic device accessory provided by this utility model can adjust the length of the data cable 3 outside the housing 1 without being limited by a fixed length, and has high flexibility, enabling the electronic device accessory to adapt to the needs of different usage scenarios. Furthermore, due to the telescopic nature of the data cable 3, it is less prone to twisting, bending, or knotting during charging, reducing damage to the data cable 3 caused by twisting, bending, or knotting, thereby improving the service life of the electronic device accessory. When not in use, the data cable 3 can be retracted to its shortest position, which not only reduces damage to the data cable 3, but also facilitates convenient storage of electronic device accessories.

[0042] In some embodiments of this application, such as Figures 1 to 3 As shown, the telescopic locking structure 4 also includes a rotating wheel 41 and a locking switch 42. The rotating wheel 41 is rotatably disposed inside the housing 1 about its own central axis, and the data cable 3 is wound around the rotating wheel 41; the locking switch 42 is disposed on the housing 1, and the locking switch 42 is configured to reciprocate between an unlocked position and a locked position relative to the housing 1 along a first direction X. When the locking switch 42 is in the unlocked position, the telescopic end 31 of the data cable 3 can extend or retract relative to the housing 1 with the rotation of the rotating wheel 41; when the locking switch 42 is in the locked position, the rotating wheel 41 is locked.

[0043] "Rotator 41 is locked" means that the rotation of rotor 41 is locked, that is, rotor 41 cannot rotate.

[0044] For example, when the locking switch 42 is in the unlocked position, when the data cable 3 is pulled at the telescopic end 31, the portion wrapped around the rotating wheel 41 exerts a force on the wheel 41, causing it to rotate. Due to the rotation of the wheel 41, the data cable 3 can extend smoothly. When the locking switch 42 is in the locked position, the rotating wheel 41 is locked, that is, the rotating wheel 41 cannot rotate. At this time, when the data cable 3 is pulled at the telescopic end 31, the portion wrapped around the rotating wheel 41 exerts a force on the wheel 41, but since the rotating wheel 41 cannot rotate, the data cable 3 cannot move, and the telescopic end 31 cannot extend or retract, thereby fixing the length of the data cable 3 outside the housing 1.

[0045] For example, when the locking switch 42 is in the unlocked position, the rotating wheel 41 rotates under the force that drives it to rotate, causing the data cable 3 to rotate synchronously, thus extending or retracting the telescopic end 31 of the data cable 3. When the locking switch 42 is in the locked position, the rotating wheel 41 is locked and cannot rotate, so the data cable 3 cannot move and the telescopic end 31 cannot extend or retract, thereby fixing the length of the data cable 3 outside the housing 1. The rotating wheel 41 can rotate around its central axis inside the housing 1, allowing the data cable 3 to be wound orderly around the outer circumference of the rotating wheel 41. The rotating wheel 41 can achieve the winding and unwinding of the data cable 3 through two opposite rotations, thereby achieving the extension and retraction of the telescopic end 31. The locking switch 42 can control the rotation and non-rotation of the rotating wheel 41. The locking switch 42 can move back and forth between the unlocked position and the locked position. When the locking switch 42 is in the unlocked position, the rotating wheel 41 can rotate. Therefore, the rotating wheel 41 will rotate when subjected to force, allowing the movable end of the data cable 3 to extend or retract.

[0046] Thus, through the cooperation of the rotating wheel 41 and the locking switch 42, the data cable 3 can be stored and the extension length of the telescopic end 31 can be adjusted. Furthermore, by using the rotating wheel 41 to wind the data cable 3, the probability of the data cable 3 twisting, bending, or knotting is reduced. At the same time, it also reduces the space occupied by the data cable 3, which is conducive to the miniaturization of electronic device components.

[0047] In some embodiments of this application, the rotating wheel 41 has a first fixing part and the locking switch 42 has a second fixing part. When the locking switch 42 is in the unlocked position, the first fixing part and the second fixing part are separated; when the locking switch 42 is in the locked position, the first fixing part and the second fixing part are locked together.

[0048] For example, the first fixing part and the second fixing part can be magnetic components, which are locked together by magnetic attraction.

[0049] For example, the first fixing part and the second fixing part can be a sawtooth structure, which is locked by the meshing of the sawtooth.

[0050] For example, the first fixing part and the second fixing part can be a structure that interlocks with each other, and are locked together by interlocking with each other.

[0051] In some embodiments of this application, the first fixing part is a first sawtooth 411 formed on the outer periphery of the rotating wheel 41, and the second fixing part is a second sawtooth 421. The first sawtooth 411 and the second sawtooth 421 can mesh with each other or separate from each other.

[0052] It is understandable that the outer circumference of the rotating wheel 41 refers to the part that surrounds the central axis of the rotating wheel 41, that is, the rotating wheel 41 has a first serration 411 that surrounds its central axis.

[0053] like Figure 3 and Figure 4 As shown, the outer peripheral edge of the rotating wheel 41 has a first serration 411, and the locking switch 42 has a second serration 421. The first serration 411 and the second serration 421 are serrated structures that can mesh with each other. These serrations can be, but are not limited to, straight serrations, oblique serrations, and curved serrations. The shape, size, and arrangement of the second serration 421 match the first serration 411, so that the second serration 421 meshes tightly and stably with the first serration 411 in the locked position and disengages from the first serration 411 in the unlocked position.

[0054] like Figure 4 As shown, when the locking switch 42 is in the unlocked position, the second sawtooth 421 is completely disengaged from the first sawtooth 411 and is in an unengaged state. At this time, the wheel 41 can rotate without being restricted by the locking switch 42. Figure 3 As shown, when the locking switch 42 is moved to the locked position, the second sawtooth 421 engages tightly with the first sawtooth 411. This physical connection prevents the rotating wheel 41 from rotating, thus achieving the locking function of the rotating wheel 41. Therefore, this embodiment of the application achieves control over the rotatability and non-rotatability of the rotating wheel 41 through the engagement and disengagement of the first sawtooth 411 and the second sawtooth 421, further realizing control over the retractability and locking of the data cable 3. Furthermore, the mutual engagement between the first sawtooth 411 and the second sawtooth 421 ensures high reliability of the locking switch 42 in locking the rotating wheel 41, reducing the possibility of the retractable end 31 extending or retracting out of control, thereby improving the stability and safety of electronic device components during use, as well as their convenience.

[0055] In some embodiments of this application, the connection structure is as follows: Figure 5 As shown, the wheel 41 includes a winding part 412 and two limiting parts 413. Each end of the winding part 412 along its axial direction is connected to a limiting part 413. The surfaces of the two limiting parts 415 facing each other form a winding groove 414 between the outer peripheral surface of the winding part 412. The data cable 3 is wound around the winding groove 414.

[0056] For example, the rotating wheel 41 is an H-shaped wheel, the limiting part 413 is a hollow disc, there are two limiting parts 413, the winding part 412 is located between the two limiting parts 413 and connected to the hollow part of the two limiting parts 413, the winding part 412 is cylindrical, the diameter of the limiting part 413 is larger than the diameter of the winding part 412, the surfaces of the two limiting parts 413 facing each other and the outer peripheral surface of the winding part 412 form a winding groove 414, the two limiting parts 413 and the winding part 412 share a common central axis.

[0057] By combining the winding portion 412 and the two limiting portions 413, a rotating wheel 41 structure is formed. The winding groove 414 formed between the facing surfaces of the two limiting portions 413 and the outer peripheral surface of the winding portion 412 provides a stable winding space for the data cable 3. The outer peripheral surface of the winding portion 412 is an annular surface surrounding the central axis of the winding portion 412, that is, the outermost layer of the winding portion 412 and the surface in contact with the data cable 3. The data cable 3 can be easily wound on the rotating wheel 41, making it easy to carry and store, reducing friction and collision between the data cable 3 and external objects, reducing twisting and knotting of the data cable 3 itself, thereby protecting the data cable 3 from damage and improving the service life of electronic device components.

[0058] In some embodiments of this application, such as Figures 4 to 6 As shown, the outer periphery of both limiting portions 413 is formed with first serrations 411, and the locking switch 42 also includes two locking plates 423, both of which are formed with second serrations 421. When the locking switch 42 is in the locked position, the first serrations 411 of the two limiting portions 413 respectively engage with the second serrations 421 of the two locking plates 423.

[0059] The engagement of the first sawtooth 411 and the second sawtooth 421 achieves mechanical locking between the limiting part 413 and the locking plate 423. The two limiting parts 413 cooperate with the two locking plates 423, improving the locking stability of the telescopic locking structure 4 in the locked state. The mutual engagement of the first sawtooth 411 and the second sawtooth 421 makes the relative position between the limiting part 413 and the locking plate 423 more precise. Each sawtooth acts as a positioning point, improving the accuracy of the locking switch 42 in the locked position.

[0060] In some embodiments of this application, such as Figure 6 As shown, the locking switch 42 also includes a base portion 424, one end of each of the two locking plates 423 is connected to the base portion 424, and the end of the locking plate 423 away from the base portion 424 forms a second serration 421.

[0061] With such a connection structure, the base part 424 simultaneously connects two locking plates 423, so that the two locking plates 423 and the base part 424 form an integral structure, which facilitates the synchronous movement of the two locking plates 423 and improves the switching speed.

[0062] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, the housing 1 has a through groove 5, the base part 424 is located outside the housing 1, and the second serration 421 of the locking plate 423 extends into the housing 1 through the through groove 5.

[0063] For example, there are two through slots 5, and the second serrations 421 of the two locking plates 423 each pass through the corresponding through slot 5 and extend into the housing 1.

[0064] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, the locking switch 42 also includes a connecting structure 422, which is connected to the base portion 424 and located between the two locking plates 423. The locking switch 42 is movably connected to the housing 1 along the first direction X through the connecting structure 422.

[0065] For example, there are two connection structures 422, which are movably connected to the housing 1, making the connection between the locking switch 42 and the housing 1 more stable, so that the locking switch 42 will not deviate or come off the housing 1 when the housing 1 moves along the first direction X.

[0066] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, one end of the connecting structure 422 is connected to the base part 424, and the other end forms a limiting head 4221. The housing 1 forms a sliding groove 6 extending along the first direction X. The limiting head 4221 of the connecting structure 422 passes through the sliding groove 6 and is limited within the housing 1. The connecting structure 422 can reciprocate relative to the sliding groove 6 along the first direction X, so that the locking switch 42 reciprocates between the unlocked position and the locked position.

[0067] For example, both connection structures 422 form a limiting head 4221, and the two limiting heads 4221 are arranged opposite to each other.

[0068] For example, the two limiting heads 4221 are respectively formed with protrusions protruding towards each other, there are two sliding grooves 6, and a sliding plate 7 is formed between the two sliding grooves 6. The minimum distance between the protrusions of the two limiting heads 4221 is less than the size of the sliding plate 7 in the spacing direction of the two limiting heads 4221, so that the two limiting heads 4221 are limited to the inside of the housing 1 by the sliding plate 7 and are not easy to fall out, thereby ensuring that the locking switch 42 will not deviate or fall out of the housing 1 when the housing 1 moves along the first direction X.

[0069] For example, the sliding groove 6 is connected to the through groove 5. The sliding groove 6 and the through groove 5 have a first end face 56 and a second end face 65 at their two ends along the first direction X. The first end face 56 can be, but is not limited to, a stepped surface. When the locking switch 42 is in the locked position, the connecting structure 422 and the locking plate 423 are in contact with the first end face 56. When the locking switch 42 is in the unlocked position, the connecting structure 422 and the locking plate 423 are in contact with the second end face 65.

[0070] In some embodiments of this application, such as Figure 4 As shown, at least one groove structure and / or protrusion structure 425 are formed on the surface of the base portion 424 facing away from the locking plate 423.

[0071] The groove structure and the raised structure 425 can increase the contact area between the base part 424 and the user's fingers or palm, and increase the coefficient of friction through changes in physical shape. This allows the user to press the base part 424 more stably when pushing or operating the locking switch 42, reducing operational errors caused by sliding or accidental touch, and improving the functionality and practicality of electronic device accessories.

[0072] For example, the surface of the base portion 424 facing away from the locking plate 423 is provided with a plurality of circular protrusions 425.

[0073] In some embodiments of this application, the locking switch 42 reciprocates between an unlocked position and a locked position along a first direction X, the first direction X being tangent to the rotation direction of the rotating wheel 41.

[0074] Because the arrangement of the unlock and lock positions is tangential to the rotation direction of the wheel 41, the user can smoothly move the lock switch 42 when pushing it. Thus, by pushing, the lock switch 42 moves back and forth between the unlock and lock positions without causing any jamming, improving the smoothness and comfort of operation.

[0075] In some embodiments of this application, the first direction X coincides with the radial direction of the rotating wheel 41.

[0076] The arrangement of the unlocked and locked positions is consistent with the radial direction of the rotating wheel 41, so that the locking switch 42 can be moved back and forth between the unlocked and locked positions by pressing the base part 424.

[0077] In some embodiments of this application, the telescopic locking structure 4 further includes an elastic reset member 43, which is connected between the housing 1 and the rotating wheel 41. The elastic reset member 43 can apply an elastic reset force to the rotating wheel 41, and the direction of the elastic reset force is opposite to the winding direction of the data cable 3 on the rotating wheel 41.

[0078] "The winding direction of the data cable 3 on the rotating wheel 41" refers to the winding direction relative to the rotating wheel 41 from the end of the data cable 3 away from the telescopic end to the telescopic end. The direction of the elastic restoring force is opposite to the winding direction of the data cable 3 on the rotating wheel 41, causing the rotating wheel 41 to rotate in a direction opposite to the winding direction of the data cable 3, so that the rotating wheel 41 winds the data cable 3, and the portion of the data cable 3 not wound on the rotating wheel 41 gradually winds further onto the rotating wheel 41. For example, the elastic restoring element 43 can be, but is not limited to, a spring, torsion spring, etc.

[0079] The elastic reset element 43 enables the rotating wheel 41 to automatically reset to its original position when no external force is applied. Figure 2 The initial state shown indicates that, with data cable 3 in its initial state, data cable 3 is almost entirely wound around the rotating wheel 41. It should be noted that, in the initial state, the elastic reset member 43 may or may not apply an elastic reset force to the rotating wheel 41.

[0080] The direction of the elastic restoring force is opposite to the winding direction of the data cable 3 on the rotating wheel 41, so that the data cable 3 can automatically retract and wind onto the rotating wheel 41 when the locking switch 42 is in the unlocked position. This simplifies the organization and storage of the data cable 3, reduces the chance of the data cable 3 twisting and knotting, thereby extending the service life of the data cable 3 and further improving the service life of electronic device components.

[0081] In some embodiments of this application, the electronic device accessory further includes a power module 2, which can supply power to the electronic device accessory and / or store electrical energy to power other devices. Thus, the electronic device accessory can be a portable power source.

[0082] In some embodiments of this application, such as Figure 1 As shown, the housing 1 includes a main shell 11 and a cover 12. The main shell 11 is a receiving cavity with an opening. The cover 12 covers the opening of the main shell 11. Part of the telescopic locking structure 4 and the power module 2 are accommodated in the receiving cavity of the housing 1.

[0083] It is understandable that the data cable 3 retracts into the housing 1, that is, it retracts into the receiving cavity of the housing 1.

[0084] For example, such as Figure 1 As shown, the main body shell 11 includes a first sidewall 111, which is parallel to a first direction X. A locking switch 42 is movably connected to the first sidewall 111 along the first direction X. At least a portion of the locking plate 423 and the connecting structure 422 of the locking switch 42 extends into the receiving cavity of the main body shell 11 to interact with the rotating wheel 41 and the data cable 3, respectively. A protruding structure 425 of the locking switch 42 is provided on the side of the base portion 424 facing away from the receiving cavity for the user to abut and push. Figure 1 As shown, the main body shell 11 also includes a second side wall 112 adjacent to the first side wall 111. The second side wall 112 has an extension opening. The telescopic end 31 of the data cable 3 extends outward through the extension opening, and the position of the extension opening is close to the position of the locking switch 42.

[0085] For example, the power module 2 includes a power control circuit disposed within the housing 1 of the power bank, a power display module disposed on the outer surface of the housing 1 of the power bank and electrically connected to the power control circuit, and a power control button disposed on the outer surface of the housing 1 of the power bank and electrically connected to the power control circuit. The power display module and the power control button are positioned close to each other. Other structures of the power module 2 can be found in the prior art and will not be described in detail here.

[0086] For example, the outer surface of the housing 1 is also provided with a power input / output interface, which is located on the second side wall 112 and spaced apart from the protrusion of the telescopic end 31. The power input / output interface can be, but is not limited to, a Type-C interface or a USB-A interface.

[0087] For example, the connector of data cable 3 can be, but is not limited to, a Type-C connector or a USB-A connector.
