[0021] Please refer to the following: Figures 1 to 10 The power bank with a replaceable power output interface 3 provided in this embodiment of the present invention will now be described. Please refer to the following for further details. Figure 2 , Figure 3 , Figure 4 and Figure 10The power bank with a replaceable power output interface 3 provided in this embodiment includes a power bank body 1, a 3-pin connector 21, a power output interface 3, and a locking structure 4. The power bank body 1 includes a power bank shell 11, a battery 12 disposed in the power bank shell 11, a control board 13 disposed in the power bank shell 11, and buttons disposed on the power bank shell 11. The battery 12 and buttons are electrically connected to the control board 13. The principle of controlling the power supply and charging of the power bank is not described in detail here. It should be noted that the control board 13 is a circuit board with various control circuits, which is implemented using existing technology in the field of power banks. The 3-pin connector 21 is electrically connected to the control board 13. The power bank shell 11 is provided with a positioning cavity 113 for accommodating and positioning the 3-pin connector 21. The 3-pin connector 21 is accommodated and positioned in the positioning cavity 113 to prevent the 3-pin connector 21 from shaking or shifting. Please refer to the following references. Figure 4 , Figure 5 and Figure 9 The power output interface 3 includes a power supply interface 31 for charging or supplying power to small electronic devices such as mobile phones and tablets, and an adapter 32 for connecting the power supply interface 31. The power supply interface 31 is located at one end of the adapter 32, and the other end of the adapter 32 is provided with a 3PIN female connector for the 3PIN pin 21 of the 3PIN connector 21 to be inserted. The power bank shell 11 is provided with a plug interface 114 for positioning and accommodating the adapter 32. The power bank shell 11 is also provided with a through hole connecting the positioning cavity 113 and the plug interface 114. The 3PIN pin 21 of the 3PIN connector 21 extends through the through hole into the plug interface 114. When the adapter 32 is inserted into the plug interface 114, the 3PIN pin 21 of the 3PIN connector 21 can be inserted into the conductive socket 22 of the 3PIN female connector, so that the power supply interface 31 is electrically connected to the control board 13 through the 3PIN connector 21. The locking structure 4 is used to lock the adapter 32 in the plug interface 114 to prevent the adapter 32 from being pulled out of the plug interface 114 by external force, thereby enabling the power supply interface 31 to be positioned on the power bank shell 11.

[0022] When using the power bank with replaceable power output interface 3 provided in this embodiment of the utility model, simply insert the adapter 32 with power supply interface 31 into the predetermined position in the plug interface 114 on the power bank shell 11. When the adapter 32 is inserted into the plug interface 114, the 3PIN pin 21 of the 3PIN pin 21 connector 2 can be inserted into the conductive socket 22 of the 3PIN female, so that the power supply interface 31 is electrically connected to the control board 13 through the 3PIN pin 21 connector 2. Then, the adapter 32 is locked in the plug interface 114 by the locking structure 4, so that the power supply interface 31 is positioned on the power bank shell 11, ensuring the stability of the electrical connection between the power supply interface 31 and the 3PIN pin 21 connector 2. Thus, the power bank can charge or supply power to small electronic devices such as mobile phones and tablets through the power supply interface 31 inserted into the plug interface 114. When the charging port malfunctions or is damaged, or when the charging port on the power bank is incompatible with the charging port of the small electronic device such as a mobile phone or tablet to be charged or powered, simply release the locking structure 4 from the adapter 32. The power supply port 31 can then be pulled out of the plug-in 114 on the power bank shell 11. A new adapter 32 with a power supply port 31 can then be inserted into the plug-in 114 on the power bank shell 11. Alternatively, an adapter 32 with a power supply port 31 that matches the charging port of the small electronic device such as a mobile phone or tablet can be inserted into the plug-in 114 on the power bank shell 11. The locking structure 4 then locks the adapter 32 into the plug-in 114, positioning the power supply port 31 on the power bank shell 11. This ensures the stability of the electrical connection between the power supply port 31 and the 3PIN connector 21. Thus, the power bank can charge or power small electronic devices such as mobile phones or tablets through the power supply port 31 inserted into the plug-in 114.

[0023] Compared with the prior art, the power bank with replaceable power output interface 3 in this embodiment of the utility model provides a 3PIN connector 21 in the positioning cavity 113 on the power bank shell 11, which is electrically connected to the control board 13 in the power bank shell 11. A plug interface 114 is provided on the power bank shell 11 at the position corresponding to the positioning cavity 113. The adapter 32 with power supply interface 31 is simply inserted into the plug interface 114, so that the conductive hole 22 of the 3PIN female on the adapter 32 is electrically connected to the 3PIN pin 21 of the 3PIN connector 21. Then, the adapter 32 is locked in the plug interface 114 by the locking structure 4, so that the power supply interface 31 is positioned on the power bank shell 11. When it is necessary to replace the power supply interface 31, simply unlock the adapter 32 by releasing the locking structure 4. Then, the old power supply interface 31 can be pulled out from the plug-in 114 on the power bank shell 11. The new adapter 32 with the power supply interface 31 can then be inserted into the plug-in 114 on the power bank shell 11. The locking structure 4 will then lock the adapter 32 with the power supply interface 31 into the plug-in 114. This allows for convenient replacement of the power supply interface 31. Thus, when the power output interface 3 malfunctions or is damaged, only the power output interface 3 needs to be replaced to use the power bank normally. This avoids the need to discard the entire power bank, thus saving users' operating costs.

[0024] Please refer to the following: Figure 1 , Figure 3 and Figure 4In some embodiments, the locking structure 4 includes a magnetic member 41 disposed on the power bank casing 11 and a magnetic member 42 that can be magnetically connected to the magnetic member 41. The magnetic member 42 is provided with a positioning sleeve hole 421 that allows the power supply interface 31 to pass through and a pressing protrusion 422 for pressing the adapter 32 against the plug interface 114. The pressing protrusion 422 is inserted into the plug interface 114 and is connected to the plug interface 114 with an interference fit. In this embodiment, by providing a magnetic suction member 41 on the power bank casing 11, when the magnetic suction member 41 magnetically fixes the magnetic member 42 to the power bank casing 11, the power supply interface 31 extends through the positioning sleeve hole 421 on the magnetic member 42 to the outside of the power bank casing 11. At the same time, the pressing protrusion 422 on the magnetic member 42 presses the adapter 32 against the plug interface 114, thereby locking the adapter 32 with the power supply interface 31 into the plug interface 114 on the power bank casing 11. This ensures that the power supply interface 31 is positioned on the power bank casing 11, guaranteeing the stability of the electrical connection between the power supply interface 31 and the 3PIN pin 21 connector 2. Thus, the power bank can charge or supply power to small electronic devices such as mobile phones and tablets by inserting the power supply interface 31 into the plug interface 114. When the power supply interface 31 needs to be replaced, simply remove the magnetic component 41 from the power bank casing 11 under external force to release the lock on the adapter 32. This allows the power supply interface 31, along with the adapter 32, to be easily pulled out of the plug-in interface 114 for replacement. Furthermore, the positioning hole 421 on the magnetic component 42 positions and straightens the power supply interface 31, preventing it from becoming misaligned during charging.

[0025] Please refer to the following: Figure 2 , Figure 4 and Figure 10 In some embodiments, the pressing protrusion 422 is a U-shaped protrusion. This U-shaped protrusion abuts against the stepped surface 33 at the connection between the power supply interface 31 and the adapter 32, enhancing the stability of the adapter 32 pressing against the plug interface 114. The central opening of the U-shaped protrusion forms a positioning sleeve hole 421, which positions and straightens the power supply interface 31, preventing it from tilting during charging.

[0026] Please refer to the following: Figure 3 , Figure 4 and Figure 6 In some embodiments, the power bank casing 11 is recessed with a first positioning groove 115 for accommodating and positioning the magnetic member 41. The magnetic member 41 is fixedly disposed in the first positioning groove 115, thereby enhancing the stability of the installation of the magnetic member 41.

[0027] Please refer to the following: Figure 2 , Figure 3 and Figure 4In some embodiments, the magnetic suction element 41 is a magnet, and the magnetic suction element 41 is a magnetic suction plate made of iron, steel or alloy material. When the magnetic suction plate is magnetically connected to the magnet, the magnetic suction plate covers the opening of the first positioning groove 115.

[0028] Please refer to the following: Figure 2 , Figure 4 , Figure 6 and Figure 10 In some embodiments, the locking structure 4 further includes multiple screws 43. The power bank shell 11 is provided with multiple internal threaded holes 116 that are adapted to the screws 43. The magnetic suction member 41 is provided with through holes 44 corresponding to the positions of each internal threaded hole 116. Each screw 43 passes through the corresponding through hole 44 and is threadedly connected to the corresponding internal threaded hole 116. The magnetic suction member 41 is fastened to the power bank shell 11 by the screws 43, preventing the magnetic suction member 41 from falling off under the action of external force. This helps to enhance the stability of the pressure protrusion 422 on the magnetic suction member 41 against the adapter 32, and prevents the adapter 32 from falling off the plug interface 114 under the pulling action of external force.

[0029] Please refer to the following: Figure 2 In some embodiments, multiple screws 43 are arranged around the positioning sleeve hole 421, and the distance between two adjacent screws 43 is equal, which enables the magnetic suction member 41 to be subjected to balanced force and ensures the stability of the pressing protrusion 422 on the magnetic suction member 41 against the adapter seat 32.

[0030] Please refer to the following: Figure 1 , Figure 3 and Figure 10 In some embodiments, the power bank casing 11 includes a first casing 111 and a second casing 112. The first casing 111 and the second casing 112 are fixedly connected by means of snap-fit ​​connection or bolt fixing. The first casing 111 is provided with a first receiving groove 117 and a second receiving groove 118. The first receiving groove 117 and the second receiving groove 118 together form a receiving cavity for accommodating and positioning the battery 12. The first casing 111 is provided with a second positioning groove 119 for accommodating and positioning the control board 13. The second casing 112 is provided with a plurality of pressing posts 45 for pressing and positioning the control board 13 in the second positioning groove 119. The multiple pressing posts 45 press the control board 13 into the second positioning groove 119, enhancing the stability of the control board 13 installation. In addition, the first casing 111 is provided with a positioning cavity 113, a plug interface 114, a first positioning groove 115, an internal threaded hole 116, and a through hole.
