[0002] The advent of mobile power banks has freed users from the worry of their electronic devices not being able to function properly while on the go. In recent years, with the increasing number and widespread use of personal devices, users have significantly increased their demand for longer-lasting backup power. This has led to the emergence of AC mobile power banks, primarily for indoor use. When a portable backup power bank runs out of power, users can simply plug the AC mobile power bank into an indoor 110-220V AC outlet to charge, eliminating the need for a separate adapter. This provides added convenience.
[0003] Currently, most AC power banks on the market feature an integrated design. While this eliminates the need to carry an adapter, it also introduces issues like bulk, inconvenience, and increased backup power costs. Furthermore, if a safety issue arises with the AC input module, the connected DC and battery modules will also experience safety issues, posing a significant safety risk. Utility Model Content

[0027] The structure of the present invention will be further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention.
[0028] Reference Figures 1 to 9 As shown, the utility model discloses a detachable mobile power supply, which includes two parts: a mobile power supply body 1 and an AC charging head 2 that can be quickly combined or separated.
[0029] The power bank body 1 can be used independently as a traditional power bank, and includes a body shell 11, a battery module 12 and a charge and discharge management module 13 arranged in the body shell 11, and a battery charging interface 14 and a battery power output interface 15 arranged on the body shell 11; wherein, the battery module 12, the battery charging interface 14 and the battery power output interface 15 are respectively connected to the charge and discharge management module 13; the battery charging interface 14 is used to obtain DC power from the AC charging head 2 to charge the battery module 12, and mobile phones and other electronic products can obtain backup power charging from the battery power output interface 15.
[0030] The AC charger 2 can be quickly separated from the power bank body 1 and used independently. In scenarios with an AC outlet, the AC charger 2 can be used as a traditional power adapter. When the power bank body 1 needs to be charged, the AC charger 2 can be quickly combined with the power bank body 1 to replenish power to the power bank body 2 without the need for wires. The AC charger 2 specifically includes a charger housing 21, a power adapter module 22 disposed within the charger housing 21, and an AC plug 23 and an adapter power output interface 24 disposed on the charger housing 21. The AC plug 23 and the adapter power output interface 24 are respectively connected to the power adapter module 22. The AC plug 23 draws AC power from a 220V AC outlet, and after voltage reduction, outputs 5V DC power through the adapter power output interface 24.
[0031] In order to facilitate the rapid combination or separation of the AC charging head 2 with the mobile power supply body 1 and to replenish the power supply body 2 with electricity without the need for wire connection, the main body shell 11 is provided with a first joint interface 111, and the charging head shell 21 is provided with a second joint interface 211 that cooperates with the first joint interface 111. The battery charging interface 14 is provided on the first joint interface 111, and the second joint interface 211 is provided with an adapter power output interface 24 that docks with the battery charging interface 14 for power supply.
[0032] The first joint interface 111 and the second joint interface 211 may be kept in contact with each other by a snap-fit structure, or by a magnetic connection between the first joint interface 211 and the second joint interface through a magnetic structure.
[0033] To enhance the stability of the connection between the power bank 1 and the AC charger 2, the first joint interface 111 and the first joint interface 211 are secured together via a positioning groove and a positioning boss. To ensure precise assembly of the power bank 1 and the AC charger 2, and to prevent damage to the battery charging port 14 or the adapter power output port 24 when docked at an incorrect angle, the positioning groove and boss are designed with anti-slip edges.
[0034] The battery power output interface 15 is provided on a side surface other than the first joint interface 111 of the main body shell 11 . When the mobile power body 1 and the AC charger 2 are combined, the battery power output interface 15 is not affected in terms of plugging and use.
[0035] The AC plug 23 is a foldable plug. When the power bank 1 and AC charger 2 are combined, the prongs of the AC plug 23 fold away, creating a flat overall appearance and making it easy to carry. To adapt the present invention to different national power outlet standards, the AC plug 23 is interchangeably connected to the charger housing 21 via a plug-in structure, allowing users to choose different AC plug standards when using the device in different countries.
[0036] During the specific implementation process, the adapter power output interface 24 can adopt a standard TYPE-C interface or a USB interface, and the battery charging interface 14 is a corresponding plug connector protruding from the first joint interface 111; the adapter power output interface shown in the drawings of this embodiment can also be used, including a first adapter power output interface 241 dedicated to docking with the battery charging interface 14 for power supply, and two second adapter power output interfaces 242 for directly powering electrical devices; the second adapter power output interface 242 is preferably two TYPE-C interfaces and is provided on the second joint interface 211.
[0037] The battery charging interface 14 comprises an insulating raised ring, and positive and negative conductive plates located on either side of the ring. The second adapter power output interface 242, recessed into the surface of the second bonding interface 211, comprises a conductive ring and a resilient conductive PIN located at the center of the ring. When the first and second bonding interfaces 111 and 211 are magnetically attracted to form a single unit, the resilient conductive PIN electrically connects to the positive conductive plate on the inner side of the insulating raised ring, while the conductive ring electrically connects to the negative conductive plate on the outer side of the ring. The unique structure of the battery charging interface 14 and second adapter power output interface 242 in this utility model effectively reduces the possibility of short circuits caused by contact with metal objects while the user is carrying the power bank in a detached state. Compared to existing AC power banks, this utility model offers greater flexibility and convenience. The power bank body and AC charging head can be replaced separately, resulting in lower costs. When the power bank body is not in use, it can be separated from the AC charging head and used independently, reducing safety risks during product use.
