[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.
[0026] To avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not of great importance are omitted. Figure 2 The charging cable 101 was removed from the power bank body 1 described below.
[0027] like Figure 1 As shown, this utility model embodiment provides a portable power bank with an attached power adapter 2, which includes a portable power bank body 1 and a power adapter 2.
[0028] Combination Figure 1 and Figure 2 As shown, the power bank body 1 includes a front shell 1a and a side shell 1b. The four edges of the front shell 1a of the power bank body 1 are adjacent to its side shell 1b. The side shell 1b is a cylindrical shell for the user to hold. The area enclosed by the front shell 1a and the side shell 1b forms an internal storage space for storing the battery cells and circuit boards. The power bank body 1 has a charging cable storage slot 10, which stores a charging cable 101. The front shell 1a of the power bank body 1 is also provided with a plurality of first magnets 11, which are arranged around the four edges of the front shell 1a.
[0029] Combination Figures 3 to 5As shown, one end of the power adapter 2 has a protruding edge ring 21. The protruding edge ring 21 is a protruding structure on the edge of the end face of the power adapter 2. The power adapter 2 has a plurality of second magnets 22 that correspond one-to-one with the first magnet 11 inside the protruding edge ring 21. The protruding edge ring 21 is connected to the front shell surface 1a of the mobile power supply body 1, and each second magnet 22 is attracted to the corresponding first magnet 11.
[0030] In the aforementioned portable power bank with included power adapter 2, the power adapter 2 is attracted to the portable power bank body 1 by magnets that cooperate with it, so that the protruding edge ring 21 of the power adapter 2 is aligned with the front shell surface 1a of the portable power bank body 1, thus achieving an integrated structure of the power adapter 2 and the portable power bank body 1. This eliminates the need for the user to carry the power adapter 2 separately, making the portable power bank adaptable to more usage scenarios and improving the user experience. When it is necessary to charge the portable power bank body 1, the power adapter 2 can be directly removed from the portable power bank body 1, releasing the attraction between the first magnet 11 and the second magnet 22, exposing the front shell surface 1a of the portable power bank body 1, and taking out the charging cable 101 from the charging cable storage slot 10. Thus, the power adapter 2 can be used to charge the portable power bank body 1 through the charging cable 101.
[0031] like Figure 4 and Figure 5 As shown, the raised edge ring 21 fits snugly against the periphery of the front shell surface 1a of the power bank body 1. The raised edge ring 21 is fitted around all the first magnets 11 and abuts against each of the first magnets 11. By utilizing the abutment between the inner side of the raised edge ring 21 and each of the first magnets 11, after the first magnets 11 and the second magnets 22 attract each other, the raised edge ring 21 acts as a limiting element on the front shell surface 1a of the power bank body 1, restricting the movement of the power adapter 2 in a direction parallel to the front shell surface 1a, thus ensuring a stable connection between the power bank body 1 and the power adapter 2. In this embodiment, the cross-sectional area of the second magnet 22 is larger than the cross-sectional area of the first magnet 11.
[0032] Furthermore, the first magnets 11 are arranged in pairs, with each pair of first magnets 11 located on two non-adjacent sides of the front shell 1a of the power bank body 1. That is, the pairs of first magnets 11 are located in opposite positions. For example, a pair of first magnets 11 is arranged on the top and bottom sides of the front shell 1a, and a pair of first magnets 11 is arranged on the left and right sides of the front shell 1a.
[0033] like Figure 2As shown, specifically, the charging cable storage slot 10 extends from the front shell surface 1a of the power bank body 1 to the side shell surface 1b, and one end of the charging cable storage slot 10 on the front shell surface 1a is located inside the raised edge ring 21. When the raised edge ring 21 is aligned with the front shell surface 1a of the power bank body 1, the raised edge ring 21 closes one end of the charging cable storage slot 10 on the front shell surface 1a, which can prevent the charging cable 101 from falling out.
[0034] Combination Figure 2 and Figure 3 As shown, similarly, the front shell 1a of the power bank body 1 is provided with an input interface 12 and an output interface 13. The power adapter 2 is provided with a charging cable interface 23 inside the raised edge ring 21. The input interface 12, output interface 13, and charging cable interface 23 are located inside the raised edge ring 21. Thus, when connected, the input interface 12, output interface 13, and charging cable interface 23 are also enclosed in the raised edge ring 21, which can prevent external dust and other foreign objects from entering the input interface 12, output interface 13, and charging cable interface 23, protect the internal circuit structure, and facilitate the long-term use of the power bank. When the power adapter 2 is removed from the power bank body 1 to charge the power bank body 1, the charging cable 101 connects the input interface 12 of the power bank body 1 and the charging cable interface 23 of the power adapter 2. When the power bank body 1 charges an electronic device, the charging cable 101 connects the output interface 13 of the power bank body 1 and the electronic device.
[0035] The power adapter 2 has a rotatable relief groove 240 on the other end opposite to the protruding edge ring 21. A pin 24 is rotatably connected in the rotatable relief groove 240. The power adapter 2 is connected to the socket through the pin 24, which can prevent the pin 24 of the power adapter 2 from protruding when carrying the power bank, thus avoiding affecting the grip and carrying.
[0036] To further facilitate users in carrying the power bank, a screw seat 14 is connected to the side shell of the power bank body 1, and a lifting strap 15 is fixed on the screw seat 14, the lifting strap 15 forming a ring structure.
[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0038] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
