[0037] Please refer again to the attached Figure 1 and attached Figure 2 In some optional embodiments, the first locking structure 13 includes a first snap-on portion 132, and the second locking structure 22 includes a second snap-on portion 222 matching the first snap-on portion 132, and the interface connector 20 is installed in the plug-in portion 11 by snapping the first snap-on portion 132 and the second snap-on portion 222 together.

[0038] In some optional embodiments, a first magnetic component 131 is provided on the bottom wall of the plug-in portion 11, and a second magnetic component 221 corresponding to the position of the first magnetic component 131 is provided in the interface connector 20, and the end surfaces of the first magnetic component 131 and the second magnetic component 221 that are close to each other repel each other.

[0039] In some optional embodiments, the interface connector 20 includes a connector base 23 and a plug portion 24 disposed on the connector base 23. The second magnetic member 221 includes two sub-magnetic members, the connector base 23 includes a first end connected to the plug portion 24 and a second end away from the first end, and the two sub-magnetic members are respectively disposed at the first end and the second end. Specifically, the two sub-magnetic members are located in the same straight line in the height direction of the interface connector 23, and the magnetic poles of the two sub-magnetic members exposed on the surface of the connector base 23 are the same.

[0040] Please see attached Figure 5 and attached Figure 6In some optional embodiments, the connector base 23 is provided with two groups of second magnetic bodies 221 on both sides of the plug part 24, which are respectively the first group of second magnetic bodies 2211 and the second group of second magnetic bodies 2212; the first group of second magnetic bodies 2211 and the second group of second magnetic bodies 2212 each include two spaced-apart sub-magnetic parts. Specifically, the connector base 23 is symmetrically provided with a first through hole and a second through hole on both sides of the plug part 24, and the first through hole and the second through hole are respectively provided with the first group of second magnetic bodies 2211 and the second group of second magnetic bodies 2212. The sub-magnetic parts can be permanent magnets or other magnetic materials.

[0041] In some optional embodiments, a first magnetic member 131 is provided on the bottom wall of the plug portion 11, a second magnetic member 221 corresponding to the position of the first magnetic member 131 is provided in the interface connector 20, and the interface connector 20 includes a connector base 23 and a plug portion 24 provided on the connector base 23, and the second magnetic member 221 has the same magnetic pole as the connection surface of the first magnetic member 131 at one end close to the plug portion 24, and the second magnetic member 221 has the opposite magnetic pole to the connection surface of the first magnetic member 131 at one end away from the plug portion 24. It should be further explained that in the first state, the first magnetic member 131 is magnetically connected to the second magnetic member 221 with the opposite magnetic pole at one end away from the plug portion 24, and the interface connector 20 is magnetically connected to the second magnetic member 221 through the first magnetic member 131, and is locked in the plug portion 11 through the first buckle portion 132 and the second buckle portion 222. Among them, the plug portion 11 can be formed by the outer surface of the body 10 being recessed into the interior of the body 10, and the plug portion 11 matches the interface connector 20. The plug-in portion 11 includes a first plug-in portion 111 for plugging into the connector base 23 and a second plug-in portion 112 for plugging into the plug portion 24, and the first plug-in portion 111 is connected to the second plug-in portion 112. Specifically, the first plug-in portion 111 is located on a side close to the outer surface of the body 10, and the second plug-in portion 112 is located on a side close to the interior of the body 10. The space size of the first plug-in portion 111 is larger than the space size of the second plug-in portion 112. The second plug-in portion 112 is opened at the center of the bottom wall of the first plug-in portion 111. The first electrical connection structure 12 is provided on the bottom wall of the first plug-in portion 111 and distributed in the circumference of the second plug-in portion 112. The first magnetic member 131 is provided in an idle area on the bottom wall of the first plug-in portion 111 where the first electrical connection structure 12 is not provided. In a specific example, the magnetic pole of the second magnetic member 221 facing away from the end of the plug portion 24 is opposite to the connecting surface of the first magnetic member 131. When the interface connector 20 is positively inserted into the first plug portion 111, the first magnetic member 131 and the second magnetic member 221 move closer to each other to generate a magnetic attraction force, so that the connector base 23 of the interface connector 20 is quickly installed in the first plug portion 111. At the same time, the second electrical connection structure 21 located on the connector base 23 abuts against the first electrical connection structure 12 located on the bottom wall of the first plug portion 111 to achieve electrical connection, and the plug portion 24 is externally located relative to the plug portion 11 for connecting the electronic product to be charged.In another specific example, the second magnetic member 221 has an end near the plug portion 24 with the same magnetic pole as the connection surface of the first magnetic member 131. When the interface connector 20 is reversely inserted into the first plug portion 111, the first magnetic member 131 and the second magnetic member 221 move closer to each other to generate a repulsive force. The connector base 23 is locked by engaging the second snap-in portion 222 on the connector base 23 with the first snap-in portion 132 in the first plug portion 111. When the interface connector 20 is removed, the repulsive force helps to push the interface connector 20 to automatically pop out of the plug portion 11, making it easier for the user to remove the interface connector 20 from the plug portion 11.

[0042] It should be further explained that the first snap-on portion 132 is located on the side wall of the first plug-in portion 111, and the second snap-on portion 222 is arranged at a position corresponding to the side wall of the connector base 23 and the first snap-on portion 132. When the interface connector 20 is positively inserted into the first plug-in portion 111, the first magnetic member 131 and the second magnetic member 221 are brought close to each other to generate a magnetic force. If the magnetic force is a magnetic attraction force, the connector base 23 can be quickly installed in the first plug-in portion 111. At the same time, the second electrical connection structure 21 located on the connector base 23 abuts against the first electrical connection structure 12 located on the bottom wall of the first plug-in portion 111 to achieve electrical connection, and the second snap-on portion 222 located on the connector base 23 is snap-connected with the first snap-on portion 132 located in the first plug-in portion 111 to lock the connector base 23, thereby preventing the interface connector 20 from being electrically disconnected due to accidental pulling or squeezing during use.

[0043] It is further explained that the first magnetic member 131 and the second magnetic member 221 are brought close to each other to generate magnetic force. If the magnetic force is a repulsive force, the interface connector 20 is installed in the plug-in portion 11 through the first buckle portion 132 and the second buckle portion 222 being snap-fitted. After the interface connector 20 is reversely inserted into the first plug-in portion 111, the connector base 23 is locked by snapping the second buckle portion 222 on the connector base 23 with the first buckle portion 132 in the first plug-in portion 111, so that the connector base 23 is stably installed in the first plug-in portion 111. At this time, the second electrical connection structure 21 on the connector base 23 faces away from the first electrical connection structure 12 on the bottom wall in the first plug-in portion 111, and the first electrical connection structure 12 and the second electrical connection structure 21 are electrically disconnected. When the connector base 23 of the interface connector 20 is reversely inserted into the first plug-in portion 111, the corresponding plug portion 24 is inserted into the second plug-in portion 112. When the interface connector 20 is removed from the plug-in portion 11, the snapping force between the first snap portion 132 and the second snap portion 222 is released. The repulsive force generated between the first magnetic member 131 and the second magnetic member 221 near one end of the plug portion 24 helps to push the interface connector 20 to automatically pop out of the plug-in portion 11, making it convenient for the user to remove the interface connector 20 from the plug-in portion 11.

[0044] Please refer again to the attached Figure 1 In some optional embodiments, the body 10 is provided with an unlocking structure, which is connected to the first locking structure 13, so that the first locking structure 13 is disconnected from the second locking structure 22. The user can control the first locking structure 13 to move away from the second locking structure 22 by operating the unlocking structure, thereby releasing the connection between the first locking structure 13 and the second locking structure 22.

[0045] Specifically, the unlocking structure includes an elastic member and a button 14, the elastic member is connected to the first locking structure 13 and the button 14 respectively, and the movement of the button 14 drives the first locking structure 13 to extend and retract on the surface of the plug-in portion 11. More specifically, the button 14 is connected to the first buckle portion 132 through the elastic member, and the user can control the first buckle portion 132 to move away from the second buckle portion 222 by operating the button 14, thereby releasing the buckling force between the first buckle portion 132 and the second buckle portion 222. In this embodiment, through the provision of the button 14, the user can easily unlock the connection between the first buckle portion 132 and the second buckle portion 222. In particular, when the connector base 23 of the interface connector 20 is reversely inserted into the first plug-in portion 111, when the interface connector 20 needs to be removed from the plug-in portion 11, the user can release the snapping force between the first snap portion 132 and the second snap portion 222 by operating the button 14. At the same time, under the action of the repulsive force generated between the first magnetic member 131 and the third magnetic connection portion 223, the interface connector 20 can be easily removed from the plug-in portion 11.

[0046] Please refer to the attached Figure 7 In some optional embodiments, the first buckle portion 132 is a protrusion, the second buckle portion 222 is a recess, and the first buckle portion 132 and the second buckle portion 222 are connected in a concave-convex matching manner. In a specific example, the body 10 has an outer wall, the outer wall of the body 10 is provided with a sliding groove, the button 14 is arranged in the sliding groove, a sliding space is formed between the outer wall of the plug-in portion 11 and the outer wall of the body 10, and a perforation matching the protrusion is provided on the outer wall of the plug-in portion 11, and the protrusion can pass through the through hole when sliding to the through hole. In actual use, the sliding of the button 14 can drive the protrusion to slide along the sliding space. When the protrusion slides to the through hole position, it can extend out of the sliding space through the through hole and abut against the recess on the interface connector 20 to achieve a locking effect. When the protrusion slides away from the through hole position, it can shrink in the sliding space and separate from the recess on the interface connector 20 to achieve an unlocking effect.

[0047] In some optional embodiments, the number of the plug-in parts 11 is at least two, and each plug-in part 11 is provided with a corresponding protrusion; each protrusion is provided with an independent button 14, that is, each protrusion has a corresponding button 14, allowing the user to individually control the locking and unlocking of the interface connector 20 in each plug-in part 11, and the user can select a specific plug-in part 11 for operation as needed without affecting other plug-in parts 11. In some other optional embodiments, multiple protrusions are provided with a button 14, that is, one button 14 controls multiple protrusions at the same time, providing users with a fast and unified operation method. In addition, this embodiment, by providing multiple plug-in parts 11 on the body 10 of the portable charging device, it can simultaneously load multiple different types of interface connectors 20, such as Type-C male head, Lightning male head, Micro-USB male head, etc., which significantly enhances the versatility and functionality of the portable charging device and meets the diverse charging and connection needs of users.

[0048] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
