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 essential portable charging devices for users' daily commutes and outdoor activities. To further enhance ease of use, most mainstream power banks on the market adopt an integrated design with a built-in data cable. These products are mainly divided into two categories: one is a power bank with a retractable function, and the other is a power bank with a lanyard-style data cable.

[0003] However, existing power banks with built-in data cables fail to achieve a seamless integration of retractable charging and portable carrying functions: for retractable cable products, the data cable can only perform the single function of extending for charging and retracting for storage, and cannot be used as a handle for users to carry or hang the power bank; for lanyard products, although the data cable can be used as a handle, the cable length is strictly limited to ensure portability, and there is no telescopic mechanism, which makes it difficult to flexibly extend to a longer length, making it difficult to adapt to long-distance charging scenarios such as users holding the power bank while using a terminal or placing the terminal at a distance. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a portable power source that solves at least one of the aforementioned technical problems. It meets the dual requirements of long-distance telescopic charging and convenient carrying or hanging, and has a simple and compact structure, is easy to operate, and improves the advantages of convenience, adaptability and practicality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a portable power bank, comprising: The housing has a storage section and a cable outlet hole. A telescopic cable module, assembled within the housing, includes a telescopic mechanism and a data cable cooperating with the telescopic mechanism. The data cable is provided with a data cable interface and a limiting component. An unlocking component, movably assembled within the housing and engaging with the data cable interface for locking or releasing the limiting member; The data cable interface is housed in the housing section, and the limiting member is movably assembled with the cable outlet hole; when the data cable interface is placed in the housing section, the data cable interface causes the unlocking component to slide and lock the limiting member.

[0006] The present invention further provides that the unlocking component includes: a sliding member slidably assembled inside the housing and correspondingly disposed to the storage part for unlocking the limiting member; an elastic member disposed between the sliding member and the storage part; and a first magnetic member disposed on the side of the sliding member facing the storage part. The data cable interface is provided with a second magnetic component on the side facing the bottom of the storage part, which magnetically engages with the first magnetic component.

[0007] The present invention further provides that the sliding member extends one or more protrusions toward the side of the limiting member, and the limiting member is provided with a locking groove that locks and engages with the protrusions.

[0008] The present invention further provides that the sliding member is provided with a receiving cavity for accommodating the limiting member and communicating with the wire outlet hole.

[0009] The present invention further includes a baffle on the limiting member for closing the outlet hole.

[0010] The present invention further includes a support member that is slidably assembled with the sliding member inside the housing.

[0011] The present invention further includes a groove on the support member and a slider at the bottom of the sliding member that slides in cooperation with the groove.

[0012] The present invention further provides that the end of the support member away from the storage part is provided with a positioning protrusion for abutting against one side of the sliding member.

[0013] 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.

[0014] The present invention further provides that the housing is also provided with a clearance hole that connects to the storage part and is used to avoid the data cable interface.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows: In this utility model, a telescopic cable module and an unlocking component slidably assembled in the housing are used. The telescopic cable module includes a telescopic mechanism and a data cable. The data cable can be flexibly extended to a relatively long length from the cable outlet hole in the housing, adapting to long-distance charging scenarios. The data cable is provided with a data cable interface and a limiting component. The data cable interface is used to unlock and cooperate with the unlocking component to lock or release the limiting component. When the data cable interface is placed in the storage section, the data cable interface and the unlocking component magnetically cooperate, driving the unlocking component to slide and lock the limiting component, thus fixing the data cable in the storage state. At this time, the exposed data cable can directly serve as a handle for the user to carry or hang the power bank. The user only needs to pull the data cable interface outward to break the magnetic cooperation, and the unlocking component slides back to release the limiting component, allowing the data cable to be freely extended. This achieves a quick switch between the handle function and the telescopic charging function, balancing convenience and practicality. Therefore, compared with earlier power banks, it fulfills the dual needs of long-distance telescopic charging and convenient carrying or hanging. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] 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.

[0021] This embodiment relates to a portable power bank, as shown in the following figure. Figures 1-3 It includes: housing 100, telescopic cable module 200 and unlocking component 300.

[0022] The housing 100 has a storage section 110 and a cable outlet 120, while the retractable cable module 200 is disposed within the housing 100 and includes a retractable mechanism 210 and a data cable 220. The data cable 220 cooperates with and is wound around the retractable mechanism 210, which is used to store or retract the data cable 220 without the need for manual cable winding. 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 long-distance charging, thus expanding its applicability. It should be noted that the retractable mechanism 210 is existing technology, providing the winding, storage, and release drive for the data cable 220, and will not be described in detail here. 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.

[0023] Furthermore, the data cable 220 is provided with a data cable interface 410, which directly connects to the electrical device. A storage section 110 is located on one side of the housing 100 to store and protect the data cable interface 410. The data cable 220 also has a limiting member 420, and a cable outlet hole 120 is located on the side of the housing 100 near the storage section 110, providing a movable and retractable channel for the limiting member 420. The limiting member 420 can move and retract within the cable outlet hole 120 without affecting the release and storage of the data cable 220.

[0024] Furthermore, referring to Figures 1-4 The unlocking component 300 is movably mounted inside the housing 100 and magnetically engages with the data cable interface 410 to lock or release the limiting member 420. When the data cable interface 410 is placed in the storage section 110, the data cable interface 410 and the unlocking component 300 magnetically engage, driving the unlocking component 300 to slide and lock the limiting member 420, thus fixing the data cable 220 in the stored state. At this time, the cable has stable structural strength and can be directly used as a handle for users to carry or hang the power bank. Furthermore, the user only needs to pull the data cable interface 410 outward to break the magnetic engagement, and the unlocking component 300 slides back to release the limiting member 420, allowing the data cable 220 to be freely extended through the telescopic mechanism 210. This achieves a quick switch between the handle function and the telescopic charging function, balancing convenience and practicality. Therefore, compared with earlier power banks, this embodiment fulfills the dual needs of long-distance telescopic charging of the data cable 220 and convenient carrying or hanging of the data cable 220.

[0025] Specifically in this embodiment, refer to Figure 3 The cable outlet 120 is a stepped hole, with a stepped surface extending along the hole wall on its inner side. A baffle 422, adapted to this stepped surface, is provided on the limiting member 420. When the data cable 220 is in the retracted state, the baffle 422 closes against the inner stepped surface of the cable outlet 120, preventing dust, moisture, and other impurities from entering the housing 100 and protecting the internal circuitry and telescopic mechanism 210. Furthermore, the baffle 422 closing on the cable outlet 120 allows the cable outlet 120 to initially position the limiting member 420, restricting its displacement along the cable outlet 120 and preventing the sliding member 310 from sliding and causing the limiting member 420 to shift. This provides a preliminary guarantee for the subsequent precise locking of the sliding member 310 and the limiting member 420. It should be noted that the cable outlet 120 can also be an inclined hole or other types, which are not limited here.

[0026] In this embodiment, refer to Figures 1-4The unlocking component 300 includes a slider 310, an elastic element 320, and a first magnetic element 330. The slider 310 is slidably mounted within the housing 100, and its axial sliding within the housing 100 switches between locking and releasing the limiting element 420. The elastic element 320 is fixedly connected between the slider 310 and the storage portion 110. When the data cable interface 410 is disengaged from the storage portion 110, the elastic restoring force of the elastic element 320 causes the slider 310 to disengage from the limiting element 420, enabling convenient unlocking by simply unplugging the data cable interface 410 without manual operation. When the slider 310 and the limiting element 420 are locked, the elastic element 320 compresses and stores energy, providing power for the unlocking action.

[0027] Furthermore, the first magnetic suction member 330, serving as the responsive end of the magnetic attraction, is installed on the side of the sliding member 310 facing the storage section 110. The second magnetic suction member 411, serving as the trigger end of the magnetic attraction, is installed on the side of the data cable interface 410 facing the bottom of the storage section 110. Through the magnetic attraction of the first magnetic suction member 330 and the second magnetic suction member 411, when the data cable interface 410 is placed in the storage section 110, the sliding member 310 is precisely aligned with the storage section 110 under the action of magnetic force, thereby locking the limiting member 420 and achieving synchronous linkage of storage and locking. Moreover, the corresponding arrangement of the sliding member 310 and the storage section 110 ensures that the magnetic directions of the first magnetic suction member 330 on the sliding member 310 and the second magnetic suction member 411 on the storage section 110 are precisely aligned, and the magnetic attraction force is concentrated, avoiding positional displacement that would cause the magnetic attraction to disperse and result in an unstable lock, thus ensuring the reliability of the lock.

[0028] It should be noted that both the first magnetic component 330 and the second magnetic component 411 can be magnets, or the first magnetic component 330 can be a magnetic metal component and the second magnetic component 411 can be a magnet. There is no need to specifically limit this.

[0029] Furthermore, referring to Figure 4 The sliding member 310 has two protruding strips 311 extending towards the limiting member 420. The limiting member 420 has locking grooves 421 on its upper and lower sides that engage with the protruding strips 311. The protruding strips 311 of the sliding member 310 and the locking grooves 421 of the limiting member 420 form a mechanical engagement, locking the data cable 220 in a retracted state. This, combined with magnetic locking, provides double protection, ensuring sufficient structural strength for the data cable 220 and increasing its ability to support the weight of the power bank, allowing for easy carrying or hanging by the user. Furthermore, the symmetrical arrangement of two protruding strips 311 and two locking grooves 421 ensures even force distribution, further improving locking stability and preventing damage from concentrated localized forces. It should be noted that the protruding strips 311 and locking grooves 421 can also be one, three, or more; this is not limited here.

[0030] Furthermore, referring to Figures 2-3 The sliding member 310 is provided with a receiving cavity 312. The receiving cavity 312 not only accommodates the limiting member 420, but also limits the sliding stroke of the sliding member 310. The receiving cavity is connected to the cable outlet hole 120 to form a through channel, ensuring that the data cable 220 moves smoothly during the stretching or retraction process, and effectively preventing the sliding member 310 from blocking or interfering with the extension and retraction of the data cable 220.

[0031] In this embodiment, refer to Figures 3-5 A support member 130 is provided within the housing 100 to provide a sliding support platform for the slider 310, and simultaneously forms a sliding assembly structure with the slider 310. Specifically, in this embodiment, the support member 130 has an axially extending groove 131, and a slider 313 is correspondingly provided at the bottom of the slider 310. The slider 313 and the groove 131 are precisely matched in size and shape. By embedding the slider 313 into the groove 131, the slider 310 can slide smoothly along the axial direction of the support member 130, avoiding deviation during the sliding process. Optionally, the mating surfaces of the groove 131 and the slider 313 can be smoothed to reduce sliding resistance, allowing the slider 310 to move lightly and smoothly under the drive of magnetic attraction or elastic restoring force, improving the user's operating feel. In some embodiments, other sliding assembly structures can also be provided between the support member 130 and the slider 310.

[0032] Furthermore, a positioning protrusion 132 is provided at the end of the support member 130 away from the storage part 110. When the slider 310 slides away from the storage part 110 under the action of elastic restoring force, the positioning protrusion 132 abuts against one side of the slider 310, preventing the slider 310 from continuing to move and avoiding the slider 313 from coming off the end of the groove 131.

[0033] In this embodiment, refer to Figures 1-2 and Figure 6 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 410, ensuring that the data cable interface 410 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 set to one, three or more, which is not limited here. In some embodiments, the storage section 110 can also be set as a storage cavity or other storage structure.

[0034] 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 410 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.

[0035] Furthermore, the housing 100 is also provided with a clearance hole 140, which connects to the storage section 110. This provides independent space for the connection between the data cable 220 and the data cable interface 410, preventing this part from being squeezed by the housing 100 during storage.

[0036] Specifically in this embodiment, refer to Figure 1 and Figure 6 The data cable 220 also includes a first cable body 430, a second cable body 440, and a conductive connector 450. The first cable body 430 is disposed between the telescopic mechanism 210 and the limiting member 420, adapting to the winding or releasing action of the telescopic mechanism 210. The second cable body 440 is disposed between the limiting member 420 and the data cable interface 410, and can serve as a handle for users to carry or hang. The conductive connector 450 is disposed within the limiting member 420 and is electrically connected to both the first cable body 430 and the second cable body 440, enabling electrical conduction between the first cable body 430 and the second cable body 440.

[0037] Specifically, in this embodiment, the first thread 430 and the second thread 440 are made of different materials. For example, the first thread 430 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 440 can be made of woven fabric, with strong toughness and outstanding tensile strength, able to stably bear the weight of the power bank and prevent the thread from breaking when lifted or hung. Furthermore, the different materials of the two threads can create visual differences, enrich the visual layers of the product, and enhance its aesthetics. In some embodiments, the first thread 430 and the second thread 440 can also be made of other materials, or both can be made of the same material.

[0038] Furthermore, the first line body 430 is provided with a first wire core 431, and the second line body 440 is provided with a second wire core 441. The first wire core 431 and the second wire core 441 are respectively connected to the two ends of the conductive connector 450 to ensure that the segmented design does not affect the power transmission and achieves seamless integration of the charging function and the handle function.

[0039] It should be noted that, in order to ensure the effective connection between the first wire core 431 and the second wire core 441 and reduce resistance loss, the conductive connector 450 can be a circuit board, conductive sheet or terminal block or other conductive device, preferably a circuit board, and there is no limitation here.

[0040] 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.
