[0001] The utility model relates to the field of electronic products, in particular to a mobile power supply with replaceable batteries. Background Art

[0002] Current power banks consist of a circuit board with a charging and discharging interface, a battery, and a housing. The battery and circuit board are electrically connected and housed within the housing, with the charging and discharging interface exposed. To charge a mobile device, the power bank is connected to the mobile phone or other terminal device via a charging cable. The mobile phone and power bank are independent of each other, making them inconvenient to handle and prone to dropping the power bank and causing the charging interface to become detached. Most importantly, when the power bank runs low, it must be removed and plugged into a charging port. This makes it difficult to charge a mobile phone when the power bank is low, forcing users to use multiple power banks, which can be detrimental to the user experience. Utility Model Content

[0012] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:

[0013] Please refer to Figure 1 and Figure 2 The mobile power supply 100 with a replaceable battery 20 of the present invention is used to be attached to a mobile terminal 200 to charge the mobile terminal 200 .

[0014] like Figure 3 The mobile power supply 100 includes a housing 10 , a battery 20 and a circuit board 30 .

[0015] The circuit board 30 is arranged at one end of the shell 10, and a first contact point 31 is provided on the side of the circuit board 30 facing the inside of the shell 10. A charging and discharging interface 32 is provided on the circuit board 30 facing the outside of the shell 10, and the charging and discharging interface 32 is exposed from the shell 10. The charging and discharging interface 32 is used to connect with the mobile terminal 200 to charge the mobile terminal 200 or replenish its own power; the shell 10 is provided with an openable and closable flip cover 11 at the other end relative to the circuit board 30, and a second contact point 12 is provided on the side of the flip cover 11 facing the shell 10. The second contact point 12 is electrically connected to the circuit board 30 through the shell 10 via a flexible connecting line 40.

[0016] The battery 20 is provided with a first electrode 21 at one end and a second electrode 22 at the other end of the battery 20 opposite the first electrode 21. The first electrode 21 and the second electrode 22 have opposite polarities. When the battery 20 is inserted into the housing 10 and the flip cover 11 is closed, the first electrode 21 contacts the first contact point 31, and the second electrode 22 contacts the second contact point 12, thereby electrically connecting the battery 20 to the circuit board 30.

[0017] In the present invention, after the mobile power supply 100 is attached to the mobile terminal 200 , the charging and discharging interface 32 of the mobile power supply 100 is connected to the charging interface of the mobile terminal 200 using a charging cable, so that the mobile power supply 100 can charge the mobile terminal 200 .

[0018] The charging and discharging interface 32 of the mobile power supply 100 includes at least one bidirectional connection port 321 and at least one magnetic interface 322 . Both the bidirectional connection port 321 and the magnetic interface 322 can be used for charging or discharging.

[0019] When the mobile terminal 200 is connected to the bidirectional connection port 321, while the mobile power supply 100 is charging the mobile phone, the mobile power supply 100 can also be charged through the magnetic interface 322, and the electricity then passes through the mobile power supply 100 to charge the mobile terminal 200, thereby ensuring that the mobile power supply 100 and the mobile terminal 200 can be charged simultaneously through only one charging cable connected to the magnetic interface 322.

[0020] When the power bank 100 is attached to the mobile terminal 200 and connected to the mobile terminal 200 via a charging cable, the mobile terminal 200 no longer needs to be frequently plugged in and unplugged. When the battery 20 of the power bank 100 is low on power, the charging cable can be connected to the magnetic interface 322 to charge both the power bank 100 and the mobile terminal 200 simultaneously. Alternatively, the flip cover 11 can be opened, the battery 20 removed, and then replaced with a fully charged battery 20 for continued use, eliminating the need for frequent plugging in and out of the interface of the mobile terminal 200. Among them, the battery 20 is provided with a first electrode 21 and a second electrode 22 that can be contacted and conductive. Similarly, a first contact point 31 and a second contact point 12 are provided in the shell 10 and on the flip cover 11. The first contact point and the second contact point are elastic contacts. When the battery 20 is inserted into the shell 10 and the flip cover 11 is closed, the first electrode 21 can just contact the first contact point 31, and the second electrode 22 can contact the second contact point 12, so that the electric energy in the battery 20 is conducted to the circuit board 30, and the mobile terminal 200 is charged through the charge and discharge interface 32 on the circuit board 30. The designed structure can facilitate the insertion and removal of the battery 20, and at the same time can play a role in preventing accidental touch connection. The design is ingenious.

[0021] In the present invention, the flip cover 11 is connected to the housing 10 via a rotating shaft 13. An elastic member 14 is provided on the flip cover 11. A stopper 15 is provided at one end of the flip cover 11 away from the rotating shaft 13. The stopper 15 includes a stopper 151 protruding from the flip cover 11. One end of the elastic member 14 is abutted against the stopper 15, and the other end is fixed in the flip cover 11. The elastic member 14 pushes the stopper 15 toward the side of the stopper 151, thereby clamping the stopper 151 on the inner wall of the housing 10 to close the flip cover 11.

[0022] When the user needs to open the flip cover 11, they manually push the stopper 15 toward the rotating shaft 13, and the stopper 151 will disengage from the housing 10, thereby opening the flip cover 11. When the user needs to close the flip cover 11, they only need to press the flip cover 11 toward the circuit board 30, and the stopper 151 will be locked on the housing 10, thereby closing the flip cover 11.

[0023] like Figure 3 In the present invention, the housing 10 includes an outer shell 16 and an inner shell 17; the battery 20 is inserted into the inner shell 17, and the outer shell 16 is sleeved on the inner shell 17. One end of the inner shell 17 is used to mount the circuit board 30, and the other end of the inner shell 17 is an opening a for inserting or removing the battery 20. One side of the circuit board 30 is connected to the flexible connecting line 40.

[0024] A magnetic array 50 is provided on at least one surface of the inner shell 17 , and the magnetic array 50 includes a plurality of magnets arranged in an array. The outer shell 16 is sleeved behind the inner shell 17 to shield the magnetic array 50 .

[0025] The magnetic array 50 is disposed on two surfaces of the inner shell 17 , and the two surfaces are opposite to each other.

[0026] The magnetic array 50 is arranged in a circular shape.

[0027] In the present invention, at least one surface of the housing 16 is provided with a recessed platform 161 for attaching decorative paintings or photos. Specifically, when the power bank 100 is attached to the mobile terminal 200, the recessed platform 161 is located on a surface facing away from the mobile terminal 200, allowing for decorative paintings or photos to be attached.

[0028] In the present invention, when a magnetic structure is also provided on the mobile terminal 200, the mobile power supply 100 can be adsorbed on the mobile terminal 200 through the magnetic array 50, and the magnetic array 50 is provided between the inner shell 17 and the outer shell 16, which is more beautiful in appearance. Figure 4 Users can also use the magnetic array 50 to attract two or more power banks 100 to each other and attach them to the mobile terminal 200, thereby increasing the power of the mobile terminal 200. In this case, one mobile terminal 200 can be connected to the charging and discharging interface 32 of another mobile terminal 200 via a charging cable. When charging is needed, the magnetic interface 322 of the outermost mobile terminal 200 can be connected to the charging port to charge multiple power banks 100 and mobile terminals 200 simultaneously. When multiple power banks 100 are connected to each other, they are connected in series, and the power capacity of the series connection is several times that of a single power bank 100.

[0029] In the present invention, the magnetic array 50 is arranged in a circular ring shape, which can quickly achieve positioning and adsorption, and is more convenient.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
