Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, specifically to a mobile power supply. Background Technology

[0002] With the widespread use of smartphones, tablets, and other mobile devices, power banks have become indispensable portable charging devices for users' daily travel and outdoor activities. To improve ease of use, existing power banks generally integrate built-in data cables, primarily retractable cables, or cables designed as lanyards. However, existing retractable cables only offer the single function of extending for charging and retracting for storage, lacking a handle or locking mechanism, making them impossible to carry. While lanyard-style cables can double as handles, their cable length is strictly limited to accommodate portability, lacking retractability and unable to achieve flexible extension over longer distances, making them unsuitable for long-distance charging scenarios. Existing products cannot simultaneously meet the dual needs of long-distance retractable charging and convenient carrying or hanging, reducing the adaptability and practicality of power banks. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a portable power supply that solves at least one of the aforementioned technical problems. It has the advantages of organically integrating retractable charging and handle functions, simple structure, convenient operation, and improved convenience, adaptability, and practicality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a mobile power supply, comprising: a housing, and a telescopic cable module assembled inside the housing; The telescopic cable module includes a telescopic mechanism and a data cable that cooperates with the telescopic mechanism. The data cable is provided with a data cable interface and a limiting member that cooperates with the data cable interface for unlocking. The housing is provided with a storage part and a cable outlet hole. The data cable interface is stored in the storage part, and the limiting member is movably assembled to the cable outlet hole. The housing is also provided with a limiting part that communicates with the cable outlet. When the data cable interface is inserted into the storage part, the data cable interface switches the limiting member from the cable outlet to the limiting part to lock the limiting member.

[0005] The present invention further provides that the limiting member is provided with a first magnetic suction member on the side facing the storage part, and the data cable interface is provided with a second magnetic suction member on the side facing the bottom of the storage part, which magnetically engages with the first magnetic suction member.

[0006] The present invention is further provided that the limiting part is a limiting hole, and the length of the limiting hole is less than the cross-sectional length of the limiting member.

[0007] The present invention is further provided that the length of the limiting hole is less than the length of the outlet hole.

[0008] The present invention further provides that the housing is provided with a movable groove for axial movement of the limiting member.

[0009] The present invention further provides that the movable groove is provided with a first avoidance hole for avoiding the data cable at one end near the telescopic mechanism.

[0010] The present invention is further provided that the storage part is a storage groove, and the side wall of the storage part is provided with a limiting protrusion for abutting against the data cable interface.

[0011] The present invention further provides that the housing is also provided with a second clearance hole that connects to the storage part and is used to avoid the data cable interface.

[0012] The present invention further includes, in addition to, a first wire body disposed between the telescopic mechanism and the limiting member, a second wire body disposed between the limiting member and the data line interface, and a conductive connector disposed within the limiting member and electrically connected to the first wire body and the second wire body.

[0013] The present invention further comprises that the first wire body is provided with a first wire core connected to one end of the conductive connector, and the second wire body is provided with a second wire core connected to the other end of the conductive connector. After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. In this utility model, the telescopic cable module installed inside the housing includes a telescopic mechanism and a data cable. The data cable can be flexibly extended to a longer length from the cable outlet of the housing, adapting to long-distance charging scenarios. The data cable is equipped with a data cable interface and a limiting member, and the limiting member and the data cable interface can be unlocked together. Furthermore, the housing is also equipped with a limiting part communicating with the cable outlet. When the data cable interface is placed in the storage part, the data cable interface and the limiting member magnetically engage, moving the limiting member from the cable outlet to the limiting part. At this time, the limiting part further locks the limiting member, and the limiting part can hold the limiting member to achieve a handle function. When the data cable interface is removed from the storage part, the magnetic force disappears, unlocking the limiting member, allowing charging of electrical devices via the data cable interface. Therefore, compared to existing power banks, it not only meets the requirement of extending the data cable length to enable long-distance charging, but also allows the data cable itself to function as a handle through the unlocking cooperation between the limiting component and the data cable interface, making it easy to carry or hang the power bank.

[0014] 2. The limiting component is equipped with a first magnetic suction component, and the data cable interface is equipped with a second magnetic suction component. The first and second magnetic suction components magnetically attract each other. Therefore, when the data cable interface is placed in the storage compartment, the limiting component moves closer to and fits against the storage compartment under the mutual magnetic attraction of the second and first magnetic suction components, and the limiting component is moved from the cable outlet hole into the limiting compartment for locking. Therefore, simply placing the data cable interface into the storage compartment allows the limiting compartment to engage the limiting component, thus achieving the handle function. The structure is simple and the operation is convenient. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to a portable power bank, as shown in the following figure. Figures 1-2The system includes a housing 100 and a retractable cable module 200. The housing 100 has a storage section 110 and a cable outlet 120. The retractable cable module 200 includes a retractable mechanism 210 and a data cable 220. The data cable 220 cooperates with and is wound around the retractable mechanism 210. The retractable mechanism 210 is used to store or release the data cable 220 without manually winding the cable. Furthermore, the data cable 220 can extend and retract from the cable outlet 120 via the retractable mechanism 210, overcoming the limitation of fixed cable length, meeting the needs of extending the data cable 220 and meeting long-distance charging requirements, thus expanding its applicability. It should be noted that the retractable mechanism 210 is existing technology, providing the drive for winding, storing, and releasing the data cable 220, and will not be described in detail here.

[0021] Specifically, in this embodiment, the power bank is also provided with other components such as a storage battery (not shown), a circuit board (not shown), a charging interface (not shown), and a button (not shown). The storage battery is connected to the data cable 220 and supplies it with power. The circuit board is electrically connected to the telescopic mechanism 210 and controls the telescopic mechanism 210 to perform winding or releasing actions.

[0022] Furthermore, the data cable 220 is equipped with a data cable interface 310 and a limiting member 320. The data cable interface 310 directly connects to the electrical device, and the limiting member 320 can extend and retract in the cable outlet 120 without affecting the release and storage of the data cable 220. The limiting member 320 cooperates with the data cable interface 310, allowing the data cable interface 310 to trigger a switching state between storage locking and use unlocking with the limiting member 320. The storage section 110 is located on one side of the housing 100 and is used to store and protect the data cable interface 310. The cable outlet 120 is located on the side of the housing 100 near the storage section 110, providing a channel for the extension and retraction of the limiting member 320. Furthermore, the housing 100 is also provided with a limiting part 130 that communicates with the cable outlet 120. When the limiting member 320 is switched to the limiting part 130, the limiting member 320 is fixed by mechanical engagement to limit the extension and retraction of the data cable 220, prevent the cable from becoming loose in the storage state, and ensure the reliability of the handle function.

[0023] When the data cable interface 310 is placed into the storage compartment 110, the data cable interface 310 and the limiting member 320 are magnetically engaged, causing the limiting member 320 to move from the cable outlet 120 to the limiting part 130. At this time, the limiting part 130 securely locks the limiting member 320 in place. Simply placing the data cable interface 310 into the storage compartment 110 will allow the limiting part 130 to firmly hold the limiting member 320, making the exposed data cable 220 a stable handle for easy carrying or hanging of the power bank. The operation is simple and convenient. When charging is needed, simply remove the data cable interface 310 from the storage compartment 110, and the limiting member 320 will automatically unlock. At this time, the user only needs to manually move the limiting member 320 back from the limiting part 130 to the cable outlet 120, and the data cable 220 can then be flexibly extended via the telescopic mechanism 210 to adapt to long-distance charging scenarios. Therefore, it not only meets the needs of long-distance telescopic charging, but also realizes the convenient carrying or hanging function, effectively taking into account dual usage scenarios and significantly improving the adaptability and practicality of the power bank.

[0024] Furthermore, referring to Figure 1 and Figure 3 A first magnetic element 321 is provided on the side of the limiting member 320 facing the storage part 110, serving as the responsive end for magnetic attraction. A second magnetic element 311 is provided on the side of the data cable interface 310 facing the bottom of the storage part 110, serving as the active end for magnetic attraction and driving the first magnetic element 321 through magnetic force. The second magnetic element 311 and the first magnetic element 321 attract each other, forming a sufficient force to move the limiting member 320, ensuring reliable locking and unlocking. Furthermore, through the magnetic attraction between the first magnetic element 321 and the second magnetic element 311, and by controlling the storage and charging states of the data cable interface 310, the locking and unlocking of the limiting member 320 is achieved. When the data cable interface 310 is placed into the storage section 110, the second magnetic member 311 and the first magnetic member 321 are precisely aligned and generate an attractive force. This force drives the limiting member 320 from the outlet hole 120 to the limiting section 130. The limiting section 130 mechanically locks the limiting member 320 securely, preventing the data cable from accidentally extending or retracting. When the data cable interface 310 is removed, the magnetic attraction between the second magnetic member 311 and the first magnetic member 321 disappears, and the limiting member 320 automatically unlocks. At this time, the user only needs to manually move the limiting member 320 back from the limiting section 130 to the outlet hole 120, and the data cable 220 can be flexibly extended through the telescopic mechanism 210, and then connected to the device through the data cable interface 310 to complete charging.

[0025] It should be noted that both the first magnetic component 321 and the second magnetic component 311 can be magnets, or the first magnetic component 321 can be a magnetic metal component and the second magnetic component 311 can be a magnet. There is no need to specifically limit this.

[0026] Furthermore, referring to Figure 3 The limiting part 130 is a limiting hole, the length of which is less than the cross-sectional length of the limiting member 320. This dimensional difference creates a physical barrier; the shorter limiting hole can hold the limiting member 320 in place, preventing it from dislodging. Once locked, the limiting member 320 fixes the length of the exposed data cable 220, forming a handle with a fixed length and stable structure. This prevents the handle from becoming loose and malfunctioning when the user lifts or hangs the cable. In some embodiments, the limiting part 130 can also be configured with other engaging limiting structures.

[0027] Furthermore, the length of the limiting hole is less than the length of the cable outlet hole 120. The cable outlet hole 120 is longer, which provides sufficient room for the limiting member 320 to move, ensuring that the limiting member 320 can slide smoothly and without jamming within the cable outlet hole 120 when the data cable 220 is extended or retracted; while the limiting hole is shorter and is only used for fixing in the locked state, and the two do not interfere with each other.

[0028] In this embodiment, refer to Figures 2-3 The housing 100 is provided with a movable groove 140, which provides a moving channel for the limiting member 320. The limiting member 320 can only move axially left and right within the moving channel to control the range of motion and avoid spatial redundancy that could lead to magnetic attraction failure.

[0029] Furthermore, the movable slot 140 is provided with a first clearance hole 141 at one end near the telescopic mechanism 210, which provides room for the data cable 220 connected to the limiting member 320 to move, avoiding interference and wear of the cable when the limiting member 320 moves. At the same time, it ensures that the limiting member 320 moves without resistance and that the data cable 220 can extend and retract smoothly.

[0030] In this embodiment, refer to Figure 1 and Figure 4 The storage section 110 is a storage groove, and a limiting protrusion 111 is provided on the side wall of the storage section 110. Specifically, there are two limiting protrusions 111, which are respectively provided on the two side walls of the storage groove, so as to jointly abut against the data cable interface 310, ensuring that the data cable interface 310 does not loosen in the stored state, and at the same time ensuring the stability of the magnetic engagement. It should be noted that the number of limiting protrusions 111 can also be one, three or more, and there is no limitation here. In some embodiments, the storage section 110 can also be configured as a storage cavity or other storage structure.

[0031] Specifically, in this embodiment, the limiting protrusion 111 and the storage part 110 adopt an integral molding structure, which significantly enhances the structural rigidity and can evenly bear the pulling force transmitted by the data cable interface 310 when the power bank is lifted. In other embodiments, the limiting protrusion 111 and the storage part 110 can also adopt a separate molding design. The limiting protrusion 111 is fixedly assembled on the side wall of the storage part 110 and can be a metal protrusion or a plastic protrusion, etc., to adapt to power bank products of different weights and specifications and diverse usage needs.

[0032] Furthermore, the housing 100 is also provided with a second clearance hole 150, which connects to the storage section 110. This provides independent space for the connection between the data cable 220 and the data cable interface 310, preventing this part from being squeezed by the housing 100 during storage.

[0033] In this embodiment, refer to Figure 4 The data cable 220 also includes a first cable body 330, a second cable body 340, and a conductive connector 350. The first cable body 330 is disposed between the telescopic mechanism 210 and the limiting member 320, adapting to the winding or releasing action of the telescopic mechanism 210. The second cable body 340 is disposed between the limiting member 320 and the data cable interface 310, and can serve as a handle for users to carry or hang. The conductive connector 350 is disposed within the limiting member 320 and is electrically connected to both the first cable body 330 and the second cable body 340, achieving electrical conductivity between the first cable body 330 and the second cable body 340.

[0034] Specifically, in this embodiment, the first thread 330 and the second thread 340 are made of different materials. For example, the first thread 330 can be made of soft plastic, possessing good flexibility and resilience, and can repeatedly wind and stretch with the telescopic mechanism 210 without breaking or getting stuck. The second thread 340 can be made of woven fabric, with strong toughness and outstanding tensile strength, capable of stably bearing the weight of the power bank and preventing thread breakage when lifted or hung. Furthermore, the different materials of the two threads can create visual differences, enriching the product's visual appeal and enhancing its aesthetics. In some embodiments, the first thread 330 and the second thread 340 can also be made of other materials, or both can be made of the same material.

[0035] Furthermore, the first line body 330 is provided with a first wire core 331, and the second line body 340 is provided with a second wire core 341. The first wire core 331 and the second wire core 341 are respectively connected to the two ends of the conductive connector 350 to ensure that the segmented design does not affect the power transmission and achieves seamless integration of the charging function and the handle function.

[0036] It should be noted that, in order to ensure the effective connection between the first wire core 331 and the second wire core 341 and reduce resistance loss, the conductive connector 350 can be a circuit board, conductive sheet or terminal block or other conductive device, preferably a circuit board, and there is no need to be specifically limited here.

[0037] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
