Description

Technical Field

[0001] This utility model relates to the field of mobile power supply technology, specifically a mobile power supply with a detachable power source. Background Technology

[0002] A portable power bank with a detachable power supply refers to a portable charging device that separates the core energy storage unit (battery) from the main circuitry through structural design, allowing the battery to be independently removed, replaced, or combined. Its core feature is the flexibility and modularity of the battery unit, which retains the portable charging function of traditional power banks while meeting users' needs for extended battery life, battery maintenance, or personalized configuration through a detachable design.

[0003] A search revealed a Chinese utility model patent, CN222673933U, which discloses a portable power bank with a detachable power supply. The power bank includes a main body and a detachable power supply unit. The main body contains a circuit board and a first battery electrically connected to the circuit board. The main body also has a first USB port for charging electronic devices and a first conductive terminal that interfaces with the detachable power supply unit. The first conductive terminal and the first USB port are electrically connected. The detachable power supply unit is detachably mounted on the main body and contains a second battery. It also has a second conductive terminal electrically connected to the first battery. The first and second conductive terminals abut against each other when the detachable power supply unit is assembled to the main body, thus expanding the power supply capacity and meeting the needs of users for extended trips. For shorter trips, only the main power supply unit needs to be carried, reducing weight and making it more convenient to carry.

[0004] However, the device's protective function needs improvement. After separating the power supply body and the detachable power supply, the conductive terminals of the power supply body need to be protected by a cover plate. However, the cover plate is carried separately and is easy to lose, resulting in the conductive terminals not being protected. In addition, the installation and separation of the power supply body and the detachable power supply are carried out by sliding, which causes friction on the surface of the conductive terminals, resulting in surface damage and affecting contact and energy transfer.

[0005] The purpose of this invention is to provide a portable power supply with a detachable power source to solve the problems mentioned in the background art.

When the insert plate 9 cannot be inserted further into the slot 8, the conductive terminal 15 abuts against the conductive terminal 21. Pinch the fixing strap 4, align the male buckle 5 with the female buckle 6 and press it in to fix it, thereby fixing the two battery packs. If a small capacity portable power bank is needed, open the fixing strap 4, separate the two battery packs, and then snap the male buckle 5 on the fixing strap 4 into the female buckle 7. Select a battery pack of appropriate capacity. Battery pack 1 and battery pack 2 are connected by direct contact, avoiding friction of the conductive terminals caused by traditional sliding connections, protecting the conductive terminals. Moreover, the connection is firm and the assembly and disassembly operations are simple through the fixing strap 4 and the insert plate 9 slot 8.
