Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and more specifically, to a portable power supply device with a retractable and switchable charging cable and lanyard function. Background Technology

[0002] Currently, with the continuous development and increasing maturity of electronic technology, portable electronic products such as mobile phones and tablets have gradually become indispensable tools in people's lives and work. As outdoor power consumption scenarios continue to increase, users are using electronic devices more frequently. However, due to the limited power storage capacity of built-in batteries in electronic devices, the demand for portable power supplies is becoming increasingly widespread.

[0003] In the existing technology, portable power banks are generally designed without a lanyard or with a separate lanyard. Although their charging cables can be extended to complete the charging function, they do not have the collaborative function of storing the charging cable and automatically converting it into a lanyard. As a result, the overall portability of the device and the flexibility of its functional application are not high. Utility Model Content

[0047] Example 1

[0048] like Figures 1 to 3 As shown, this utility model embodiment provides a portable power bank device with a retractable and switchable charging cable and lanyard function. It includes a power bank body 1, a charging cable structure 2, and a cable limiting structure 3. The power bank body 1 effectively serves as the functional and assembly foundation of the overall device. Simultaneously, the charging cable structure 2, in addition to achieving the predetermined adaptive and extendable charging function, can further work with the cable limiting structure 3 to retract the charging end 23 and automatically convert the cable into a lanyard accessory, thereby significantly improving the overall functional flexibility and portability. The specific settings are as follows:

[0049] Please refer to Figures 1 to 3The power bank body 1 serves as the functional and assembly foundation of the overall device. The charging cable structure 2 includes a cable retracting body 21 and a power receiving end 22 and a charging end 23 respectively disposed at both ends of the cable retracting body 21. The cable limiting structure 3 includes a limiting seat 31 and a limiting storage groove 32. The power receiving end 22 of the cable retracting body 21 is detachably connected to the power output end of the power bank body 1 via a snap-fit ​​connection. The limiting seat 31 is positioned at one end of the cable retracting body 21 near the power receiving end 22. The limiting storage groove 32 is an arc-shaped groove with an opening on one side, and the limiting storage groove 32 is formed on one side of the limiting seat 31. At the side position, the charging end 23 is detachably and retainably housed inside the retaining and storage groove 32, which effectively serves as a storage space for the power receiving end 22. The retaining seat 31 is also provided with an end retaining part 33 on the inner side of the end of the retaining and storage groove 32 away from the power receiving end 22. The cross-sectional area of ​​the channel formed by the end retaining part 33 in the retaining and storage groove 32 is larger than the cross-sectional area of ​​the cable retractor body 21 and smaller than the cross-sectional area of ​​the charging end 23. This allows the charging end 23 to effectively form a lateral and pull-out retaining function in relation to the retaining and storage groove 32, thereby enabling it to be effectively switched to the lanyard function when the charging end 23 is stored, improving the flexibility of the function application.

[0050] Example 2

[0051] In Example 2, the same symbols are used for the same structures as in Example 1, and the same descriptions are omitted. Example 2 differs from Example 1 in that, please refer to... Figure 4 The limiting seat 31 is slidably mounted on one end of the take-up and unwinding body 21 near the power terminal 22, and the sliding assembly structure between the limiting seat 31 and the take-up and unwinding body 21 includes, but is not limited to, damped sliding and bolt-locked sliding, so as to more flexibly adjust the position of the limiting seat 31 and the size of the rope hook.

[0052] Example 3

[0053] In Example 3, the same symbols are used for the same structures as in Example 1, and the same descriptions are omitted. Example 3 differs from Example 1 in that, please refer to... Figure 5 The main body 21 of the retractable cable is further fitted with a flexible soft sleeve 35 between the power receiving end 22 and the limiting seat 31. The two ends of the flexible soft sleeve 35 are respectively fixedly connected to the power receiving end 22 and the limiting seat 31. This is to further improve the positioning regularity of the main body 21 when it is in the storage state by means of the deformable characteristics of the flexible soft sleeve 35, thereby enhancing the overall functionality and practicality.

[0054] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
