[0002] A power bank is a portable charger that can be carried by an individual and can store electricity. It is mainly used to charge handheld mobile devices and other consumer electronic products (such as wireless phones and laptops). It is especially used in situations where there is no external power supply. Its main components include: batteries for storing electricity, circuits for stabilizing output voltage, and most mobile power banks come with chargers to charge the built-in batteries.

[0003] Nowadays, the batteries of many mobile phones or electronic devices are not removable, but there are still a large number of electronic devices with removable batteries on the market. By directly replacing the battery, the electronic products can be restored to power and used at the fastest speed. However, the current power bank can only charge the electronic devices directly, and cannot achieve the purpose of charging the backup battery and directly replacing the battery for the electronic devices. For this reason, we designed a two-in-one device of lithium battery and power bank. Utility Model Content

[0021] See also Figure 1-2 : A two-in-one device of a lithium battery and a power bank, comprising a power bank body 1 and a lithium battery body 2. A placement slot 3 adapted to the lithium battery body 2 is opened on the top left side of the power bank body 1. The lithium battery body 2 is placed in the placement slot 3. The lithium battery body 2 is relatively independent of the power bank body 1. The lithium battery body 2 can be pulled out to replace the battery of the electronic device. When the lithium battery body 2 is not in use, the lithium battery body 2 can be inserted into the placement slot 3, which is convenient for storing and carrying the lithium battery body 2.

[0022] A slot 4 is provided at the top of the power bank body 1 and is vertically arranged with the placement slot 3. A sealing plate 5 is inserted inside the slot 4. A sealing slot 6 corresponding to the sealing plate 5 is provided at the top of the left side wall of the placement slot 3. The left end of the sealing plate 5 is inserted into the sealing plate 5. A rubber sealing gasket 11 is fixedly connected to the left side wall of the sealing slot 6. The sealing plate 5 can seal the opening of the placement slot 3 to prevent the lithium battery body 2 in the placement slot 3 from slipping out. The left end of the sealing plate 5 is inserted into the sealing slot 6.

[0025] In another embodiment, a guide groove 12 is formed on the side wall of the mounting groove 7 and is slidably connected to the side wall of the limiting plate 8. A pulling plate 13 is fixedly connected to the top of the sealing plate 5. The pulling plate 13 can more conveniently apply force to the sealing plate 5, making it easier to pull the sealing plate 5. The setting of the guide groove 12 can ensure smooth and stable movement of the sealing plate 5.

[0026] In another embodiment, an insulating shock-absorbing pad 14 is fixedly connected to the bottom wall of the placement groove 3, a first charging contact 15 is provided at the bottom of the lithium battery body 2, and a second charging contact 16 electrically connected to the power bank body 1 is installed on the inner bottom wall of the placement groove 3. The insulating shock-absorbing pad 14 can protect the bottom of the lithium battery body 2. Through the contact between the first charging contact 15 and the second charging contact 16, the power bank body 1 can charge the lithium battery body 2, ensuring that the circuit of the lithium battery body 2 is maintained at a high level, so that the lithium battery body 2 can be taken out for use conveniently.

[0027] In summary, when the utility model is in use, the sealing plate 5 can be more conveniently applied with force by pulling the plate 13, and the sealing plate 5 is pulled to the right. At this time, the limiting plate 8 is restricted by the mounting groove 7 to ensure that the sealing plate 5 slides to the right. At this time, the reset spring 9 is compressed. As the sealing plate 5 slides to the right, the opening of the placement groove 3 is exposed, and the lithium battery body 2 placed in the placement groove 3 can be taken out for use. The replaced lithium battery body 2 can be placed in the placement groove 3 again, and then the sealing plate 5 is released. The reset spring 9 can reset and push the limiting plate 8 and the sealing plate 5 to reset, and the opening of the placement groove 3 is re-blocked.
