Description

Charging device Technical Field

[0001] This application relates to the field of electronic device accessories technology, and more particularly to a charging device. Background Technology

[0002] Currently, electronic devices such as smartphones, smartwatches, and tablets have become essential tools in people's daily lives, and their usage frequency is increasing. However, electronic devices have limited battery life, so people choose to carry portable power banks with them to charge these electronic devices outdoors.

[0003] Some existing power banks require users to carry their own data cables to connect the power bank and electronic devices. Others have plugs directly installed on the power bank for connecting to electronic devices. However, the plugs are usually fixed to the power bank's casing and protrude from the surface, making them easily damaged when the power bank is dropped. In addition, the fixed plugs on the surface of the power bank detract from its overall aesthetics and affect the user experience. Summary of the Invention

[0014] The pop-out structure includes an elastic element disposed on the body, and the elastic element is at least partially located within the storage portion.

[0015] In some embodiments, the charging device further includes a wire, and the connecting device is connected to the body via the wire. The connecting device also includes a second usage state. In the second usage state, one end of the wire connected to the connecting device extends out of the storage portion, and the connecting device is separated from the body.

[0016] In some embodiments, the body is provided with a groove that connects the storage portion to the outside of the body, and one end of the wire can movably pass through the groove and be connected to the connecting device.

[0017] In some embodiments, the storage portion has a first opening, and the wire groove has a second opening; an anti-detachment portion is provided on the outer side of the main body, and the anti-detachment portion is located between the first opening and the second opening.

[0058] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0059] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom, etc.) in the embodiments of this application are only used to explain the relative positional relationship between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0060] It should also be noted that when a component is referred to as "fixed to" or "set on" another component, the component may be directly on the other component or there may be an intervening component present. When a component is referred to as "connected to" another component, it may be directly connected to the other component or there may be an intervening component present.

[0061] [First Embodiment]

[0062] Please refer to Figures 1 to 8. A charging device 1 provided in the first embodiment of this application includes a body 12 and a connecting device 13 electrically connected to the body 12. The connecting device 13 includes a plug 131 and a base 132. The plug 131 protrudes from the outside of the base 132 and is used for electrical connection with an electronic device, such as a mobile phone. That is, the plug 131 can be inserted into the charging port of the electronic device, while the base 132 is located outside the charging port. The charging device 1 can achieve the effect of connecting the body 12 and the electronic device through the connecting device 13, thereby charging the electronic device using the body 12. The charging device 1 has its own connecting device 13 for connecting to the electronic device, so the user does not need to carry an additional data cable, making it convenient for the user. Specifically, the charging device 1 is a power bank.

[0063] The main body 12 is provided with a storage part 121, and the connecting device 13 is movably disposed in the storage part 121. The connecting device 13 has a storage state and a first use state. In the storage state, the plug 131 is stored in the storage part 121. Therefore, when the connecting device 13 is not needed and the electronic device is not charged, the connecting device 13 can be stored in a storage state to protect the plug 131, reduce the risk of the plug 131 being damaged when the connecting device 13 is not in use, and also reduce the abruptness of the connecting device 13 when it is not in use, so as to improve the overall aesthetics of the charging device 1.

[0064] Understandably, in the stored state, the base 132 of the connecting device 13 can be partially or entirely stored inside the storage section 121, or it can be entirely located outside the storage section 121.

[0065] Preferably, in the stored state, the base 132 is stored in the storage part 121, and the outer surface of the connecting device 13, i.e. the outer surface of the base 132, smoothly transitions with the outer surface of the body 12, so as to further reduce the abruptness of the connecting device 13.

[0066] When the connecting device 13 is in the first use state, the base 132 is at least partially housed within the storage portion 121, and the plug 131 protrudes at least partially from the storage portion 121. When the user needs to charge the electronic device, the connecting device 13 can be switched from the storage state to the first use state, so that the plug 131 protrudes from the storage portion 121 to connect to the electronic device. At this time, the base 132 of the connecting device 13 is still housed within the storage portion 121, and the connecting device 13 is not separated from the main body 12, making the overall appearance of the charging device 1 more aesthetically pleasing.

[0067] Preferably, in the first use state, the connecting device 13 and the storage part 121 of the body 12 are relatively fixed in the depth direction (i.e., the extension direction of the plug 131 when it is located in the storage part 121), so as to prevent the connecting device 13 from falling out of the storage part 121 or retracting into the storage part 121 during use. This can avoid the problem of the plug 131 retracting during the process of inserting the plug 131 into the charging port of the electronic device, which would affect the plugging operation.

[0068] The specific method by which the connecting device 13 switches between the storage state and the first use state is not limited. For example, it can be done by rotating the connecting device 13 so that the plug 131 is stored inside the storage part 121 or protrudes outside the storage part 121. Alternatively, it can be done by driving the connecting device 13 to slide along the depth direction of the storage part 121 so that the plug 131 protrudes outside the storage part 121 or retracts into the storage part 121. Alternatively, it can be done by separating the connecting device 13 from the body 12 and then inserting the plug 131 into the storage part 121 with the plug facing inward or protruding the plug 131 outward.

[0069] In one embodiment, the storage part 121 includes a locking position 1212 and an unlocking position 1211. When the connecting device 13 is in the locking position 1212, the connecting device 13 and the body 12 remain relatively fixed in the depth direction of the storage part 121, forming a locking effect. When the connecting device 13 is in the unlocking position 1211, the connecting device 13 and the body 12 can move relative to each other in the depth direction of the storage part 121, releasing the locking effect and allowing the connecting device 13 to be taken out from the storage part 121, separating the connecting device 13 from the body 12, so that the connecting device 13 can switch between the storage state and the first use state.

[0070] In both the storage state and the first use state, the connecting device 13 is in the locked position 1212, thereby achieving a locking effect and enhancing the stability of the connecting device 13 in both the storage state and the first use state.

[0071] In this embodiment, the storage part 121 is a long strip-shaped groove, and the connecting device 13 can slide within the storage part 121 along the length direction of the storage part 121, thereby switching between the unlocking position 1211 and the locking position 1212. When the connecting device 13 is needed, it can be first slid within the storage compartment 121 to move from the locking position 1212 to the unlocking position 1211. The connecting device 13 is then removed from the storage compartment 121. The base 132 of the connecting device 13 is then inserted into the unlocking position 1211 of the storage compartment 121 with the plug 131 facing outwards. The connecting device 13 is then moved from the unlocking position 1211 to the locking position 1212 to achieve a locking effect, placing the connecting device 13 in the first use state. After charging is complete, the connecting device 13 in the first use state can be moved from the locking position 1212 to the unlocking position 1211. The connecting device 13 is then removed and inserted into the unlocking position 1211 of the storage compartment 121 with the plug 131 facing inwards. Finally, the connecting device 13 is moved from the unlocking position 1211 to the locking position 1212 to achieve the storage state.

[0072] Specifically, the locking position 1212 and the unlocking position 1211 are located at the two ends of the storage part 121, respectively. By driving the connecting device 13 to move from one end of the storage part 121 to the other end, the position of the connecting device 13 can be switched between the locking position 1212 and the unlocking position 1211.

[0073] In one embodiment, a limiting structure 14 is provided between the body 12 and the connecting device 13. When the connecting device 13 is in the locked position 1212, the limiting structure 14 locks the connecting device 13 and the body 12. That is, when the connecting device 13 is in the locked position 1212, it is relatively fixed to the body 12 through the limiting structure 14.

[0074] The limiting structure 14 includes a limiting block 141 and a limiting part 142. The limiting block 141 is disposed on the inner wall of the receiving part 121, and the limiting part 142 is disposed on the outer wall of the base 132 of the connecting device 13. The limiting block 141 and the limiting part 142 are correspondingly arranged. When the connecting device 13 is in the locked position 1212, the limiting block 141 is located inside the limiting part 142, forming a locking effect. When the connecting device 13 is in the unlocked position 1211, the limiting block 141 is removed from the limiting part 142, and the limiting block 141 and the limiting part 142 are separated, forming an unlocking effect.

[0075] Specifically, the limiting block 141 is a protruding strip, and the limiting part 142 is a limiting groove. Both are elongated and extend along the length direction of the receiving part 121, i.e. the sliding direction of the connecting device 13. Thus, when the connecting device 13 is in the locking position 1212, the cooperation of the limiting block 141 and the limiting part 142 can keep the connecting device 13 and the body 12 relatively fixed in the depth direction of the receiving part 121, i.e., in the direction perpendicular to the sliding direction of the connecting device 13, and form a sliding fit effect in the length direction of the receiving part 121.

[0076] In another embodiment, the limiting block 141 may be disposed on the outer wall of the connecting device 13, and the limiting part 142 may be disposed on the inner wall of the storage part 121.

[0077] The specific number of limiting structures 14 is not limited; there can be one or more. In this embodiment, limiting structures 14 are respectively provided between the opposite sides of the base 132 and the body 12. The limiting structures 14 located on the opposite sides of the base 132 are symmetrically arranged, that is, limiting portions 142 are respectively provided on the opposite sides of the base 132, and limiting blocks 141 are respectively provided on the two opposite inner walls of the storage portion 121. The limiting portions 142 and limiting blocks 141 located on the opposite sides of the connecting device 13 are symmetrically arranged. By providing limiting structures 14 on the opposite sides of the base 132, the stability of the connecting device 13 when it is in the locking position 1212 can be enhanced. At the same time, since multiple limiting blocks 141 and multiple limiting portions 142 are symmetrically arranged, the limiting blocks 141 can be selected to cooperate with different limiting portions 142 in different states of the connecting device 13, which is convenient for users.

[0078] Specifically, there are two limiting structures 14, that is, there are two limiting blocks 141 and two limiting parts 142. The two limiting blocks 141 are respectively provided on the two inner walls opposite to each other of the storage part 121, and the two limiting parts 142 are respectively provided on the opposite sides of the base 132.

[0079] In this embodiment, the outer wall of the limiting block 141 is provided with a positioning protrusion 1411, and the inner wall of the limiting part 142 is provided with a corresponding positioning recess 1421. The positioning protrusion 1411 can be selectively inserted into the positioning hole or withdrawn from the positioning recess 1421. That is, when the connecting device 13 is in the locking position 1212, the limiting block 141 is located in the limiting part 142, and the positioning protrusion 1411 is located in the positioning recess 1421. The positioning protrusion 1411 and the positioning recess 1421 cooperate to form a certain limiting effect in the sliding direction of the connecting device 13, so as to position the connecting device 13 at this position. When the external force on the connecting device 13 reaches a certain level, the positioning protrusion 1411 withdraws from the positioning recess 1421, the positioning effect is released, and the limiting block 141 can withdraw from the limiting part 142.

[0080] In another embodiment, the positioning protrusion 1411 may also be provided on the inner wall of the limiting portion 142, and the positioning recess 1421 is correspondingly provided on the outer wall of the limiting block 141.

[0081] In other embodiments, the limiting structure is not limited to being composed of a protrusion and a limiting groove. For example, a spring positioning pin and a positioning hole can be provided on the connector and the charging body respectively, and the locking effect can be achieved by the cooperation of the spring positioning pin and the positioning hole. Alternatively, an electromagnetic component can be provided on the charging body, and a spring can be provided between the electromagnetic component and the charging body. When the electromagnetic component is energized, it exits from the storage part and squeezes the spring, so that the connector can be taken out from the storage part. After the power is turned off, the electromagnetic component extends into the storage part under the action of the spring and inserts into the groove structure on the connector to form a locking effect.

[0082] In one embodiment, the main body 12 includes a housing 122, an energy storage component 123, and a circuit board 124. A storage portion 121 is disposed on the housing 122, and a connecting device 13 is movably engaged with the housing 122. Both the energy storage component 123 and the circuit board 124 are located inside the housing 122, and the energy storage component 123 and the connecting device 13 are electrically connected to the circuit board 124. The energy storage component 123 can store electrical energy, such as a rechargeable battery. When the connecting device 13 is connected to an electronic device, the energy storage component 123 can charge the electronic device through the circuit board 124 and the connecting device 13.

[0083] The specific method of electrical connection between the connecting device 13 and the circuit board 124 is not limited. For example, the electrical connection can be achieved through a wire or through a similar male-female plug-in connection. In this embodiment, the charging device 1 also includes a wire 110. The connecting device 13 is connected to the body 12 through the wire 110. That is, one end of the wire 110 is connected to the connecting device 13, and the other end is connected to the circuit board 124 of the body 12, thereby realizing the electrical connection between the connecting device 13 and the circuit board 124.

[0084] The connecting device 13 also includes a second usage state. In the second usage state, one end of the wire 110 connected to the connecting device 13 extends out of the storage portion 121, and the connecting device 13 retracts from the storage portion 121. At this time, the connecting device 13 is separated from the body 12, i.e., it is no longer in direct contact. The connecting device 13 has two different usage states. One state is that the connecting device 13 is not separated from the body 12, and the other state is that the connecting device 13 is separated from the body 12. The user can select the appropriate usage state according to the actual situation for user convenience.

[0085] The two ends of the wire 110 are connected to the main body 12 and the connecting device 13 respectively. The part of the wire 110 is located outside the main body 12 and has a ring-like structure, thus forming a hand-holding space 111. The user can carry the charging device 1 in his hand or on his wrist through the hand-holding space 111 for easy carrying.

[0086] The main body 12 is provided with a wire groove 125. The wire groove 125 extends from the unlocking position 1211 of the storage part 121 to the outside of the main body 12 along the sliding direction of the connecting device 13. One end of the wire 110 movably passes through the wire groove 125 and connects to the connecting device 13. Specifically, the wire groove 125 is a wire hole provided on the outer shell 122. The wire hole extends from one end of the storage part 121 near the unlocking position 1211 to the outside of the outer shell 122. One end of the wire 110 passes through the wire hole from the outside of the outer shell 122 and extends into the storage part 121 to connect with the connecting device 13. The part of the wire 110 is located outside the outer shell 122. When the user pulls the wire 110 outward, the connecting device 13 can be driven to slide in the direction from the locking position 1212 to the unlocking position 1211.

[0087] The storage section 121 has a first opening 1213 on the side near the surface of the main body 12, through which the connecting device 13 can be inserted into or withdrawn from the storage section 121. Furthermore, the wire groove 125 has a second opening on the side near the surface of the main body 12, through which the wire 110 passes. The second opening is, for example, a wire groove opening 1252.

[0088] An anti-detachment part 126 is provided on the outer side of the main body 12. The anti-detachment part 126 is located between the first opening 1213 and the second opening, and the wire 110 passes through the wire groove 125 and the storage part 121 and abuts against the anti-detachment part 126. In this embodiment, the first opening 1213 and the second opening are located on two adjacent and perpendicular sides of the main body 12, and the anti-detachment part 126 is the turning angle at the junction of the surfaces where the first opening 1213 and the second opening are located.

[0089] When the connecting device 13 is in the unlocked position 1211, the end of the connecting device 13 connected to the wire 110 abuts against the anti-detachment part 126 near the storage part 121. The wire 110 can abut against the anti-detachment part 126 inside the wire groove 125, so that the wire 110 can only pass through the openings at both ends of the wire groove 125. The anti-detachment part 126 is provided on the wire groove 125 to prevent the wire 110 from exiting from the wire groove 125, thereby preventing the wire 110 from separating from the body 12 when the charging device 1 is held, and increasing the lifting strength.

[0090] In one embodiment, the wire 110 is located on one side of the sliding direction of the connecting device 13, and the plug 131 is located on the side of the connecting device 13 perpendicular to its sliding direction, so that the end of the wire 110 connected to the connecting device 13 and the plug 131 are perpendicular to each other. The direction in which the wire 110 is inserted into the receiving part 121 is perpendicular to the direction in which the connecting device 13 slides within the receiving part 121, thus preventing the wire 110 from affecting the switching of the connecting device 13 between different states.

[0091] The circumferential dimension of the base 132 is larger than that of the plug 131, forming a T-shaped or L-shaped effect. The storage part 121 includes a first groove 1214 and a second groove 1215. The second groove 1215 is located on one side of the first groove 1214 and is connected to the first groove 1214. The side of the first groove 1214 away from the second groove 1215 is the first opening 1213 of the storage part 121. The circumferential dimension of the first groove 1214 is larger than that of the second groove 1215, so that the body 12 forms a step 1216 on the side of the first groove 1214 close to the second groove 1215.

[0092] In the stored state, the base 132 is housed within the first groove 1214, and the plug 131 is housed within the second groove 1215. When the connecting device 13 slides within the storage portion 121, the base 132 slides within the first groove 1214, and the plug 131 slides within the second groove 1215. In the first use state, the base 132 is housed within the first groove 1214, the plug 131 protrudes from the body 12 in a direction away from the second groove 1215, and the side of the base 132 away from the plug 131 abuts against the step 1216. During the process of switching the connecting device 13 to the first use state, the base 132 of the connecting device 13 can be inserted into the first groove 1214 of the storage part 121 until the base 132 abuts against the step 1216. The step 1216 forms a limiting effect on the connecting device 13, preventing it from being inserted further into the storage part 121. At this time, the limiting part 142 on the connecting device 13 is aligned with the limiting block 141 in the storage part 121. Pushing the connecting device 13 towards the locking position 1212 will automatically insert the limiting block 141 into the limiting part 142. The user does not need to deliberately align the limiting block 141 and the limiting part 142, which is convenient for the user.

[0093] In one embodiment, a push-pull portion 1321 is provided on the side of the base 132 away from the plug 131. The push-pull portion 1321 can increase the friction between the connecting device 13 and the user's finger or provide a force point, so that the user can push the connecting device 13 to slide when the connecting device 13 is stored in the storage portion 121.

[0094] The specific form of the push-pull portion 1321 is not limited; it can be a raised texture protruding from the surface of the base 132, or a recessed portion forming the surface of the base 132. In this embodiment, the push-pull portion 1321 is a recessed portion.

[0095] The connecting device 13 has a handle 133 on its outer circumferential side. When the connecting device 13 is taken out of the storage part 121, the user can hook the handle 133 with his / her finger to provide a point of force and make it easier for the user to take out the connecting device 13.

[0096] Understandably, the handle position 133 can be a protruding structure or a groove structure. In this embodiment, the handle position 133 is a groove, which is located on the side of the base 132 away from the wire 110.

[0097] In one embodiment, the charging device 1 further includes a pop-out structure 15, which is provided corresponding to the unlock position 1211 to provide a force to drive the connecting device 13 to move outward toward the storage portion 121 when the connecting device 13 is in the unlock position 1211, so that the connecting device 13 at least partially protrudes outward from the storage portion 121, so that the user can remove the connecting device 13 from the storage portion 121.

[0098] Specifically, the force generated by the pop-out structure 15 is insufficient to push the entire connecting device 13 out of the storage part 121. The connecting device 13 protrudes out of the storage part 121, forming a raised state. At this time, the user can hook the handle position 133 with his hand and take the connecting device 13 out of the storage part 121.

[0099] Understandably, this force can be the elastic force of an elastic element or the repulsive force between magnets.

[0100] In this embodiment, the pop-out structure 15 includes a first magnetic member 151 and a second magnetic member 152. The first magnetic member 151 is mounted on the body 12, and the second magnetic member 152 is mounted on the connecting device 13. The first magnetic member 151 is positioned close to the unlocking position 1211. When the connecting device 13 is in the unlocking position 1211, the first magnetic member 151 and the second magnetic member 152 are positioned opposite each other and repel each other, thereby pushing the connecting device 13 to move outward from the storage section 121.

[0101] In other embodiments, the pop-out structure can also be an elastic element such as a spring or sheet located in the locking position. The elastic element is located inside the storage part. When the connector moves to the unlocking position, the connector will squeeze the elastic element and deform it. After the connector is released, the connector will move out of the storage part under the elastic force of the elastic element. Alternatively, the pop-out structure can also be part of the wire. For example, when the connector moves from the locking position to the unlocking position, causing the wire to deform, the wire will also generate a certain elastic force. The elastic force generated by the wire will be used to push the connector out of the storage part.

[0102] [Second Embodiment]

[0103] Referring to Figures 9 to 12, the second embodiment of this application provides a self-contained charging device 1. Compared with the aforementioned embodiments, the main difference lies in the structure of the body 12 and the data cable 11. Specifically, the self-contained charging device 1 includes a body 12, a wire 110, and an interface connector 20. The body 12 has a charging circuit inside. One end of the wire 110 is electrically connected to the charging circuit, and the other end has an electrical connector 30. The interface connector 20 is detachably connected to and electrically connected to the electrical connector 30. It is worth mentioning that when the interface connector 20 and the electrical connector 30 are electrically connected, their combination is the same as that of the connection device 13 in the above embodiments, and can be used to connect with other electronic devices and transmit power. Correspondingly, the combination of the interface connector 20, the electrical connector 30, and the wire 110 can achieve the same function as the combination of the wire 110 and the connection device 13 in the above embodiments. It can be explained that the interface connector 20 being detachably connected to the electrical connector 30 means that the interface connector 20 can be easily removed from the electrical connector 30 without damaging the structure of the interface connector 20 and the electrical connector 30 itself. The self-cable charging device 1 can be a self-cable power bank, a self-cable charging head, or a self-cable power strip, etc.

[0104] The wire 110 of the self-contained charging device 1 is provided with an electrical connector 30. The interface connector 20 is detachably connected to the electrical connector 30 and electrically connected to the electrical connector 30, so that users can connect different types of interface connectors 20 to the wire 110 through the electrical connector 30 as needed, thereby improving the versatility and compatibility of the self-contained charging device 1.

[0105] In some optional embodiments, a storage portion 121 is provided on one side of the main body 12, and the electrical connector 30 is detachably disposed within the storage portion 121. The electrical connector 30 has a stored state within the storage portion 121 and a detached state removed from the storage portion 121. The interface connector 20 is detachably mounted on the electrical connector 30 and electrically connected to the electrical connector 30. It can be explained that the end of the wire 110 connected to the charging circuit is usually fixed and will not come out of the main body 12, while the end connected to the electrical connector 30 is movable. The user can move the electrical connector 30 to a target position as needed. Specifically, the electrical connector 30 can be stored within the storage portion 121 to form a stored state, or it can be removed from the storage portion 121 to form a detached state.

[0106] In this embodiment, a storage section 121 is provided on one side of the main body 12. The electrical connector 30 is detachably disposed in the storage section 121, so that the electrical connector 30 has a storage state stored in the storage section 121 and a detached state removed from the storage section 121. Users can remove or store the electrical connector 30 as needed, and can also replace the interface connector 20 on the electrical connector 30 as needed, making the use of the charging device more convenient in different situations.

[0107] Please refer to Figures 13 and 14. In some optional embodiments, the electrical connector 30 is provided with a connection groove 31, and the interface connector 20 includes a connector base 21 and a plug 131 disposed on the connector base 21. The connector base 21 is detachably connected to the connection groove 31.

[0108] In some optional embodiments, a first limiting part 311 is provided on the side wall of the connecting groove 31. The first limiting part 311 is used to provide a locking force for installing the interface connector 20 in the connecting groove 31. It should be further noted that a second limiting part 211 is provided on the connector base 21, which engages with the first limiting part 311. When the interface connector 20 is installed in the connecting groove 31, the cooperation of the first limiting part 311 and the second limiting part 211 can provide a locking force to securely install the interface connector 20 in the connecting groove 31, preventing the electrical connection from being disconnected due to accidental pulling or squeezing during use.

[0109] In some optional embodiments, the electrical connector 30 has a first electrical connection part 32 in the connection groove 31, and the connector base 21 has a second electrical connection part 22 that is adapted to the first electrical connection part 32. Specifically, the first electrical connection part 32 is located on the bottom wall of the connection groove 31 and is located in the middle area of ​​the bottom wall. The middle area of ​​the side of the connector base 21 facing away from the plug 131 has a second electrical connection part 22 that matches the first electrical connection part 32. The connector base 21 of the interface connector 20 can be inserted into the connection groove 31. The positions of the first electrical connection part 32 and the second electrical connection part 22 correspond to each other. The interface connector 20 and the electrical connector 30 are electrically connected through the contact of the first electrical connection part 32 and the second electrical connection part 22.

[0110] In some optional embodiments, the storage portion 121 is a recessed portion 128 formed on one side of the body 12. The thickness of the electrical connector 30 is less than or equal to the height of the recessed portion 128. The recessed portion 128 is used to place the electrical connector 30. By making the thickness of the electrical connector 30 less than or equal to the height of the recessed portion 128, the electrical connector 30 can be completely stored in the recessed portion 128, which increases the aesthetics and feel of the self-connected charging device 1.

[0111] Please refer to Figure 10. In some optional embodiments, a wire groove 125 is also provided on one side of the body 12. The wire groove 125 is used to place the wire 110. The wire groove 125 is connected to the storage part 121, specifically connected to the recessed part 128. In the storage state, at least a portion of the wire 110 near the electrical connector 30 is stored in the wire groove 125, and the electrical connector 30 is stored in the recessed part 128.

[0112] In some optional embodiments, a wire groove 125 is disposed within the body 12, having a first port 1251 communicating with the receiving portion 121. A wire 110 at least partially passes through the wire groove 125, with one end of the wire 110 near the electrical connector 30 movably passing through the first port 1251. The recessed portion 128 can be formed by the outer surface of the body 12 recessing into the interior of the body 12. The space of the recessed portion 128 matches the volume of the electrical connector 30 after the interface connector 20 is installed, allowing the electrical connector 30 to be better housed within the recessed portion 128 after the interface connector 20 is installed.

[0113] Referring to Figure 12, in some optional embodiments, one side of the main body 12 is provided with a wire groove opening 1252 communicating with the storage part 121; in the stored state, a portion of the wire 110 protrudes outside the wire groove opening 1252 to form a handle 112. Specifically, in the stored state where the electrical connector 30 is stored in the storage part 121, one end of the wire 110 is locked by the charging circuit, and the other end is locked by the electrical connector 30. A portion of the wire 110 is folded through the wire groove opening 1252 and protrudes outside the wire groove opening 1252 to form a handle 112. On the one hand, this allows the wire 110 to be neatly stored on the main body 12, and on the other hand, a portion of the wire 110 is folded and protrudes outside the wire groove opening 1252 to form a handle 112 for the user to grip.

[0114] Referring to Figures 11 and 15, in some optional embodiments, the wire groove 125 includes a positioning part 1253 and a wire-locking part 1254. Both the positioning part 1253 and the wire-locking part 1254 are groove-shaped and are connected to each other through a second port 1255. At least a portion of the wire 110 near the charging circuit is fixedly installed in the positioning part 1253, and the remaining portion of the wire 110 outside the positioning part 1253 is movably installed in the wire-locking part 1254. The two ends of the wire-locking part 1254 are respectively connected to the storage part 121 and the side wall of the body 12, and penetrate through the edge of the side wall of the body 12. A portion of the wire 110 near the electrical connector 30 is disposed in the wire-locking part 1254. The electrical connector 30 is placed in the storage part 121, and the portion of the wire 110 connected to the electrical connector 30 is locked in the wire-locking part 1254 for storage. The positioning part 1253 and the wire-locking part 1254 can be stacked vertically along the depth direction of the wire groove 125. The positioning part 1253 is located on the side closer to the interior of the main body 12, and the wire-locking part 1254 is located on the side closer to the outer surface of the main body 12. It can be explained that at least a portion of the wire 110 near the charging circuit is fixedly installed in the positioning part 1253, meaning that the wire 110 located in the positioning part 1253 is locked along its length. The remaining portion of the wire 110 outside the positioning part 1253 is movably installed in the wire-locking part 1254, meaning that the remaining portion of the wire 110 outside the positioning part 1253 can move freely.

[0115] Referring to Figure 11, in some optional embodiments, the wire-holding portion 1254 is a semi-enclosed structure with an opening in the circumference. The two ends of the wire-holding portion 1254 are respectively provided with a first port 1251 for the wire 110 to pass through and a second port 1255 opposite to the first port 1251. The wire 110 is detachably disposed within the wire-holding portion 1254. Because the wire 110 is detachably disposed within the wire-holding portion 1254, the user can remove or put back the wire 110 as needed during use, satisfying the user's long-distance charging needs while allowing the wire 110 to be retracted when the user is charging at close range or when it is not needed, thus reducing space occupation. It can be explained that the semi-enclosed structure with an opening in the circumference of the wire-holding portion 1254 means that the wire-holding portion 1254 forms an operating space for the user to remove or put back the wire 110.

[0116] Referring to Figure 9, in some other optional embodiments, the wire clamping portion 1254 is a circumferentially closed structure. The two ends of the wire clamping portion 1254 are respectively provided with a first port 1251 for the wire 110 to pass through and a second port 1255 opposite to the first port 1251. The wire 110 is retractably disposed within the wire clamping portion 1254. By retractably disposing of the wire 110 within the wire clamping portion 1254, the user can lengthen or shorten the wire 110 as needed, increasing the flexibility of use. The size design of the first port 1251 and the second port 1255 allows the wire 110 to slide along its length, but prevents the electrical connector 30 from sliding into the wire clamping portion 1254. It can be explained that the circumferentially closed structure of the wire clamping portion 1254 means that when the wire 110 slides inside the wire clamping portion 1254, it is at least partially installed within the wire clamping portion 1254, limiting the wire 110 and facilitating the user's lengthening or shortening of the wire 110. Furthermore, by providing a circumferentially enclosed structure for the cable clamping part 1254, the cable 110 is stored in a stowed state when not in use. When the middle part of the cable 110 protrudes from the outside of the cable groove opening 1252 to form the handle 112, the section of the cable 110 near the electrical connector 30 is confined inside the cable clamping part 1254 when the user lifts the self-contained charging device 1 through the handle 112, thereby avoiding the risk of the cable 110 falling out of the cable clamping part 1254.

[0117] Referring to Figure 10, in some optional embodiments, an interface portion 127 is also provided on one side of the body 12. The interface portion 127 has a space that matches the interface connector 20 for placing another interface connector 20 that supports different models. The interface portion 127 can be formed by the outer surface of the body 12 being recessed into the interior of the body 12. The interface portion 127 has a first space that matches the connector base 21 and a second space that matches the plug 131. The first space and the second space are connected. The interface portion 127 can accommodate another interface connector 20 that supports different interface standards.

[0118] In some other alternative embodiments, an interface portion 127 is also provided on one side of the body 12. The interface portion 127 is provided with another electrical connector 30 that can be electrically connected to the interface connector 20. Another interface connector 20 that supports different interface standards is detachably disposed in the interface portion 127.

[0119] It should be further noted that the interface connector 20 includes, but is not limited to, Type-C male connectors and Lightning male connectors. The Type-C male connector is suitable for newer devices from brands such as Huawei, Honor, Xiaomi, and Samsung, including smartphones, tablets, and other electronic devices that support Type-C male connectors. It supports data transfer and fast charging, and its reversible plugging capability improves user convenience. The Lightning male connector is suitable for Apple's iPhone, iPad, and iPod devices, supporting data transfer and charging. In some other optional embodiments, the interface connector 20 also includes a Micro-USB male connector, which is suitable for some earlier Android devices and some small electronic devices such as small fans and Bluetooth headsets. This embodiment, by providing a diverse range of interface connectors 20, enables the charging device to cover a broad electronic device market, ensuring that users of different electronic devices can find suitable charging and data transfer solutions for their devices.

[0120] Referring to Figure 14, in some optional embodiments, the electrical connector 30 is provided with a first magnetic attraction part 33, and the interface connector 20 is provided with a second magnetic attraction part 23. The interface connector 20 is detachably mounted on the electrical connector 30 through a magnetic connection between the first magnetic attraction part 33 and the second magnetic attraction part 23. The first magnetic attraction part 33 and the second magnetic attraction part 23 approach each other, generating a magnetic attraction force, which allows the connector base 21 of the interface connector 20 to be quickly mounted on the electrical connector 30, and the two achieve electrical connection. The plug 131 protrudes outside the electrical connector 30 for connecting the electronic device to be charged. Specifically, when the connector base 21 is mounted on the electrical connector 30 through the magnetic attraction force between the first magnetic attraction part 33 and the second magnetic attraction part 23, the first electrical connection part 32 on the electrical connector 30 abuts against the second electrical connection part 22 on the connector base 21 to achieve electrical connection between the connector base 21 and the electrical connector 30.

[0121] In some optional embodiments, the electrical connector 30 is provided with a slot 34 that mates with the plug 131; the slot 34 communicates with the connecting groove 31, and the slot 34 and the connecting groove 31 correspond to the plug 131 and the electrical connector 30, respectively. When the interface connector 20 is mounted on the electrical connector 30, it has a first mounting state and a second mounting state. In the first mounting state, the plug 131 faces away from the slot 34, and in the second mounting state, the plug 131 faces the slot 34 and is inserted into the slot 34. It should be further explained that, in the first installation state, the second electrical connection part 22 on the connector base 21 matches the first electrical connection part 32 on the electrical connection seat 30 to realize the electrical connection between the connector base 21 and the electrical connection seat 30. At this time, the plug 131 of the interface connector 20 faces away from the slot 34, so that the plug 131 can connect to the external electronic device to be charged, thereby realizing the charging needs of the external charging electronic device. In the second installation state, the second electrical connection part 22 on the connector base 21 and the first electrical connection part 32 on the electrical connection seat 30 are arranged back to back, so that the electrical connection between the connector base 21 and the electrical connection seat 30 is disconnected. At this time, the plug 131 of the interface connector 20 faces the slot 34 and is inserted into the slot 34.

[0122] [Third Embodiment]

[0123] Referring to Figure 16, the third embodiment of this application provides a mobile power bank body, which is the power body part of the charging device 1 in the aforementioned embodiments. Compared with the aforementioned embodiments, the main difference lies in the structure of the main body 12 and the interface connector 20 of the mobile power bank body. Specifically, the mobile power bank body includes a main body 12, which has a charging circuit inside. One side of the main body 12 has at least one first insertion position 411 for accommodating the connector base 21 of the external interface connector 20. The first insertion position 411 has a third electrical connection part 42 that is electrically connected to the charging circuit, and the third electrical connection part 42 is used to electrically connect to the connector base 21 of the interface connector 20.

The first insertion position 411 contains a third electrical connection portion 42 for electrical connection with the connector base 21 of the interface connector 20. This design allows users to electrically connect different types of interface connectors 20 to the power bank via the third electrical connection portion 42 as needed, thereby improving the versatility and compatibility of the power bank. Furthermore, the first insertion position 411 provides an installation location for the interface connector 20 and increases the stability of the connection between the interface connector 20 and the power bank. There may be one or multiple first insertion positions 411. Multiple first insertion positions 411 can accommodate different types of interface connectors 20, making the power bank more versatile. When multiple first insertion positions 411 are provided, they are arranged along the length of the power bank, including the main body 12.

[0125] Please refer to Figure 16 again. In some optional embodiments, a second plug-in position 412 is provided on one side of the body 12. The first plug-in position 411 and the second plug-in position 412 are connected. The second plug-in position 412 is used to accommodate the plug 131 of the interface connector 20.

[0126] Specifically, the first insertion position 411 is a first receiving groove 413 recessed on one side of the body 12, and the second insertion position 412 is a second receiving groove 414 recessed on one side of the first insertion position 411. The space of the second receiving groove 414 is smaller than the space of the first receiving groove 413. The first receiving groove 413 and the second receiving groove 414 are connected. The first receiving groove 413 matches the connector base 21, and the second receiving groove 414 matches the plug 131.

[0127] In some optional embodiments, the first receiving groove 413 and the second receiving groove 414 are interconnected along the central axis of the first receiving groove 413. Specifically, the first receiving groove 413 and the second receiving groove 414 are interconnected along the height of the first receiving groove 413. More specifically, the first receiving groove 413 and the second receiving groove 414 may be sequentially formed by recesses from the outer surface of the body 12 towards the interior of the body 12, with the second receiving groove 414 located on the side closer to the interior of the body 12 and the first receiving groove 413 located on the side closer to the outer surface of the body 12.

[0128] In some optional embodiments, the first plug-in position 411 has a bottom wall 4111, and the third electrical connection portion 42 is disposed on the bottom wall 4111. In a specific example, there are two third electrical connection portions 42, respectively disposed at both ends of the top of the second plug-in position 412. It should be further noted that there may also be multiple third electrical connection portions 42, with the second plug-in position 412 located at the center of the bottom wall 4111 of the first plug-in position 411, and multiple third electrical connection portions 42 located on the bottom wall 4111 of the first plug-in position 411 and circumferentially around the second plug-in position 412.

[0129] In some alternative embodiments, the power bank body further includes a locking component 401, the first plug-in position 411 having a side wall 4112 connected to the bottom wall 4111, the bottom wall 4111 and the side wall 4112 being connected to form a first receiving groove 413, and the locking component 401 being disposed on the bottom wall 4111 and / or the side wall 4112.

[0130] In some optional embodiments, the locking component 401 includes a third magnetic attraction portion 43, which is disposed on the bottom wall 4111. Specifically, there are two third magnetic attraction portions 43, which are respectively disposed at both ends of the top of the second insertion position 412. A third electrical connection portion 42 is disposed between the third magnetic attraction portion 43 and the top of the second insertion position 412.

[0131] In some optional embodiments, the locking component 401 includes a first latching portion 441 disposed on the side wall 4112. Specifically, the first latching portion 441 is a protrusion, and there are two protrusions, which are respectively located on two oppositely disposed side walls 4112.

[0132] In some optional embodiments, the second insertion position 412 is provided with a transmission structure electrically connected to the charging circuit. The transmission structure is used to electrically connect to the plug 131 of the interface connector 20. For example, the plug 131 is a male connector socket, the transmission structure is a female connector socket, and the transmission structure is interconnected with the plug portion 20 to realize data transmission.

[0133] [Fourth Embodiment]

[0134] Referring to Figures 13, 17, and 18, the fourth embodiment of this application provides a charging combination device 1. The charging combination device 1 includes an interface connector 20 and a mobile power supply body as described in the third embodiment. A charging circuit is provided inside the body 12. At least one first insertion position 411 is provided on one side of the body 12, and a third electrical connection portion 42 electrically connected to the charging circuit is provided within the first insertion position 411. The first insertion position 411 does not include the top of the second insertion position 412. In this embodiment, the first insertion position 411 includes a first receiving groove 413, which does not include the opening of the second receiving groove 414. The third electrical connection portion 42 is disposed on the wall of the first receiving groove 413. The interface connector 20 includes a connector base 21 and a plug 131 disposed on the connector base 21. A second electrical connection portion 22 is provided on the side of the connector base 21 away from the plug 131. The connector base 21 and the first insertion position 411 are electrically connected through the third electrical connection portion 42 and the second electrical connection portion 22.

[0135] The charging combination device 1 in this embodiment includes the mobile power bank body of any one of the above third embodiments, and therefore has the technical effects of the corresponding mobile power bank body embodiment, which will not be repeated here.

[0136] In some optional embodiments, the power bank body includes a second plug-in position 412, and the interface connector 20 has a first retracted state and a second retracted state. In the first retracted state, the plug 131 of the interface connector 20 protrudes from the outer surface of the first plug-in position 411, and the connector base 21 of the interface connector 20 is electrically connected to the third electrical connection portion 42 in the first plug-in position 411. In the second retracted state, the plug 131 of the interface connector 20 is retracted into the second plug-in position 412, the connector base 21 of the interface connector 20 is disconnected from the third electrical connection portion 42 in the first plug-in position 411, and the plug 131 of the interface connector 20 can be electrically connected to the transmission structure in the second plug-in position 412. Specifically, in the first retracted state, the interface connector 20 is electrically connected to the third electrical connection portion 42 within the first plug-in position 411, and the plug 131 of the interface connector 20 protrudes from the outer surface of the first plug-in position 411, allowing the plug 131 to connect to an external electronic product to be charged, thereby fulfilling the charging needs of the external electronic product. In the second retracted state, the interface connector 20 is electrically disconnected from the third electrical connection portion 42 within the first plug-in position 411, and the plug 131 of the interface connector 20 is retracted into the second plug-in position 412. This reduces the size of the power bank body, making it more convenient to carry. Furthermore, when charging is not required, retracting the plug 131 into the second plug-in position 412 can prevent damage to the plug 131 caused by friction or pressure during the transport of the power bank body.

[0137] The interface connector 20 is housed within the first insertion position 411 in a first orientation, thus being in a first housed state; the interface connector 20 is also housed within the first insertion position 411 in a second orientation opposite to the first orientation, thus being in a second housed state. It should be further noted that a plug 131 is provided at the front end of the connector base 21, and a second electrical connection portion 22 is provided at the rear end of the connector base 21. It can be explained that the first direction refers to the interface connector 20 being stored in a first storage state with the rear end of the connector base 21 close to the first plug position 411. In this state, the plug 131 of the interface connector 20 protrudes from the outer surface of the first plug position 411, allowing the plug 131 to connect to an external electronic product for charging. The second direction refers to the interface connector 20 being fully stored in a second storage state with the plug 131 close to the first plug position 411. In this state, the second electrical connection part 22 of the interface connector 20 is disconnected from the third electrical connection part 42 in the first plug position 411, and the plug 131 is hidden inside the second plug position 412. This reduces the space occupied by the main body of the power bank and protects the plug 131, preventing damage to the plug 131 due to friction or pressure during carrying.

[0138] Please refer to Figures 19 and 20. In some optional embodiments, the connector base 21 is provided with a second magnetic attraction part 23, and the first insertion position 411 is provided with a third magnetic attraction part 43 corresponding to the position of the second magnetic attraction part 23.

[0139] In some alternative embodiments, the connector base 21 is provided with a second latching portion 241, and the first insertion position 411 is provided with a first latching portion 441 that cooperates with and connects to the second latching portion 241.

[0140] In some optional embodiments, the third electrical connection portion 42 includes multiple metal pillars or multiple metal plates. Specifically, one of the third electrical connection portion 42 and the second electrical connection portion 22 is multiple metal pillars, and the other is multiple metal plates linked one-to-one with the multiple metal pillars. The fact that the third electrical connection portion 42 is disposed on the bottom wall 4111 within the first insertion position 411 ensures that when the interface connector 20 is inserted into the first insertion position 411 in the first direction, the second electrical connection portion 22 on the interface connector 20 can align and abut against it, achieving an effective electrical connection. This embodiment, through the cooperation of the metal pillars and metal plates, ensures a more precise and stable connection between the second electrical connection portion 22 on the interface connector 20 and the third electrical connection portion 42 on the bottom wall 4111 within the first insertion position 411, facilitating installation and reducing charging failures caused by poor contact.

[0141] In a preferred embodiment, the third electrical connection part 42 is a metal post, and the second electrical connection part 22 is a metal sheet that matches the metal post. In the second storage state, the second electrical connection part 22, that is, the metal sheet, can be stored as completely as possible in the first plug-in position 411 to form a better storage state.

[0142] In some optional embodiments, the number of first plug positions 411 is at least two, and the number of interface connectors 20 corresponds to the number of first plug positions 411, including multiple connectors. The plugs 131 of the multiple interface connectors 20 support different interface standards. It should be further noted that a third electrical connection part 42 can be provided on the bottom wall 4111 of each of the multiple first plug positions 411, so that the multiple first plug positions 411 can simultaneously have storage and charging functions.

[0143] In some optional embodiments, the power bank body further includes a stand storage compartment 16 and a stand 60. The stand storage compartment 16 is formed by a recess in the interior of the body 12 from the outer surface of the body 12. The stand 60 has a supported state and a folded state relative to the stand storage compartment 16. In the supported state, the stand 60 can hold electronic products. Specifically, the stand storage compartment 16 is located on one side of the body 12, with the larger side of the body 12. The stand 60 matches the stand storage compartment 16, and one side of the stand 60 is rotatably connected to the stand storage compartment 16, allowing the stand 60 to have both a supported state and a folded state relative to the stand storage compartment 16. The power bank body provided in this embodiment not only provides charging functionality but also, through the integrated stand 60, allows users to more conveniently view or operate electronic products while charging them. In actual operation, when users need to use electronic products while charging, they can take the stand 60 out of the stand storage compartment 16 and rotate it to the supporting state. At this time, the stand 60 can stably support the electronic products, allowing the electronic products to be tilted at a suitable viewing or operating angle. After use, users can rotate the stand 60 back into the stand storage compartment 16 to return it to the folded state, reducing the space occupied and making it convenient for users to carry.

[0144] [Fifth Embodiment]

[0145] Referring to Figures 20 and 21, the fifth embodiment of this application provides a portable charging device. Compared with the aforementioned embodiments, the main difference lies in the structure of the portable charging device's body 12 and interface connector 20. Specifically, the portable charging device includes a body 12 and an interface connector 20; a plug-in portion 40 is provided on one side of the body 12, and a first locking structure 44 is provided within the plug-in portion 40; the interface connector 20 is provided with a second locking structure 24 that matches the first locking structure 44, and the first locking structure 44 and the second locking structure 24 are connected to lock the interface connector 20 within the plug-in portion 40. The body 12 contains a charging circuit, the plug-in portion 40 contains a third electrical connection portion 42 that is electrically connected to the charging circuit, and the interface connector 20 is provided with a second electrical connection portion 22 that is adapted to the third electrical connection portion 42.

[0146] In this embodiment, a plug-in portion 40 is provided on one side of the main body 12. A first locking structure 44 is provided within the plug-in portion 40, and a second locking structure 24 is provided within the interface connector 20. The interface connector 20 achieves a locked connection with the plug-in portion 40 through the connection of the first locking structure 44 and the second locking structure 24, ensuring the stability of the electrical connection between the interface connector 20 and the plug-in portion 40. Furthermore, a third electrical connection portion 42, which is electrically connected to the charging circuit, is provided within the plug-in portion 40. The interface connector 20 has a second electrical connection portion 22. The interface connector 20 achieves an electrical connection with the plug-in portion 40 through the abutment of the second electrical connection portion 22 and the third electrical connection portion 42. Through the cooperation of the electrical connection structure and the locking structure, the user can easily install and remove the interface connector 20, while ensuring the stability of the electrical connection between the interface connector 20 and the plug-in portion 40.

[0147] Referring to Figures 22 to 25, in some optional embodiments, the interface connector 20 includes a connector base 21 and a plug 131 disposed on the connector base 21. It is worth noting that the interface connector 20 has a first state of being inserted into the mating portion 40 in a forward direction and a second state of being inserted into the mating portion 40 in a reverse direction. In the first state, the plug 131 is external relative to the mating portion 40, and in the second state, the plug 131 is internal relative to the mating portion 40. It should be further noted that the plug 131 is disposed at the front end of the connector base 21, and a second electrical connection portion 22 is disposed at the rear end of the connector base 21. It can be explained that forward insertion means that the interface connector 20 is inserted with the rear end of the connector base 21 close to the plug portion 40. In the first state, the second electrical connection portion 22 of the interface connector 20 matches the third electrical connection portion 42 in the plug portion 40 to achieve electrical connection. The plug 131 of the interface connector 20 protrudes from the outer surface of the body 12, so that the plug 131 can connect to an external electronic product to be charged, thereby meeting the charging needs of the external electronic product. Reverse insertion means that the interface connector 20 is inserted with the plug 131 close to the plug portion 40. In the second state, the second electrical connection portion 22 of the interface connector 20 is disconnected from the third electrical connection portion 42 in the plug portion 40. The plug 131 is built into the plug portion 40, which protects the plug 131 from damage caused by friction or pressure during carrying, and also avoids current leakage caused by accident.

[0148] The plug 131 is typically designed according to specific standards, such as Type-C, Lightning, or Micro-USB interfaces, to adapt to various electronic products that need to be charged, such as smartphones and tablets. This embodiment provides diverse interface connectors 20, enabling the capsule power bank to cover a broad electronic product market and ensuring that users of different electronic products can find suitable charging and data transfer options for their devices.

[0149] Please refer again to Figures 20 and 21. In some optional embodiments, the first locking structure 44 includes a first latching portion 441, and the second locking structure 24 includes a second latching portion 241 that matches the first latching portion 441. The interface connector 20 is installed in the plug-in portion 40 by engaging the first latching portion 441 and the second latching portion 241.

[0150] In some optional embodiments, the bottom wall of the plug portion 40 is provided with a third magnetic attraction portion 43, and the interface connector 20 is provided with a second magnetic attraction portion 23 corresponding to the position of the third magnetic attraction portion 43. The end faces of the third magnetic attraction portion 43 and the second magnetic attraction portion 23 that are close to each other repel each other.

[0151] In some optional embodiments, the interface connector 20 includes a connector base 21 and a plug 131 disposed on the connector base 21. The second magnetic attraction portion 23 includes two sub-magnetic elements. The connector base 21 includes a first end connecting to the plug 131 and a second end opposite to the first end. The two sub-magnetic elements are respectively disposed at the first end and the second end. Specifically, the two sub-magnetic elements are located on the same straight line in the height direction of the interface connector 20, and the magnetic poles of the two sub-magnetic elements exposed on the surface of the connector base 21 are the same.

[0152] Referring to Figures 24 and 25, in some optional embodiments, the connector base 21 has two sets of second magnetic parts 23 extending through both sides of the plug 131, namely a first magnetic body 231 and a second magnetic body 232; each of the first magnetic body 231 and the second magnetic body 232 includes two spaced-apart sub-magnetic elements. Specifically, the connector base 21 has a first through hole and a second through hole symmetrically arranged on both sides of the plug 131, and the first magnetic body 231 and the second magnetic body 232 are respectively installed in the first through hole and the second through hole. The sub-magnetic elements can be permanent magnets or other magnetic materials.

[0153] In some optional embodiments, the bottom wall of the plug portion 40 is provided with a third magnetic attraction portion 43, and the interface connector 20 is provided with a second magnetic attraction portion 23 corresponding to the position of the third magnetic attraction portion 43. The interface connector 20 includes a connector base 21 and a plug 131 disposed on the connector base 21. The end of the second magnetic attraction portion 23 near the plug 131 has the same magnetic pole as the connecting surface of the third magnetic attraction portion 43, and the end of the second magnetic attraction portion 23 away from the plug 131 has the opposite magnetic pole to the connecting surface of the third magnetic attraction portion 43. It should be further noted that in the first state, the third magnetic attraction portion 43 and the second magnetic attraction portion 23 with the opposite magnetic pole to the end away from the plug 131 are magnetically connected. The interface connector 20 is magnetically connected to the third magnetic attraction portion 43 and the second magnetic attraction portion 23, and is locked in the plug portion 40 by the snap-fit ​​connection of the first snap-fit ​​portion 441 and the second snap-fit ​​portion 241. The plug portion 40 can be formed by the outer surface of the body 12 recessed into the interior of the body 12, and the plug portion 40 matches the interface connector 20. The insertion portion 40 includes a first insertion position 411 for inserting into the connector base 21 and a second insertion position 412 for inserting into the plug 131. The first insertion position 411 and the second insertion position 412 are in communication. Specifically, the first insertion position 411 is located on the side near the outer surface of the body 12, and the second insertion position 412 is located on the side near the interior of the body 12. The space size of the first insertion position 411 is larger than the space size of the second insertion position 412. The second insertion position 412 is located at the center of the bottom wall of the first insertion position 411. The third electrical connection portion 42 is provided on the bottom wall inside the first insertion position 411 and distributed around the second insertion position 412. The third magnetic attraction portion 43 is provided in the empty area on the bottom wall inside the first insertion position 411 where the third electrical connection portion 42 is not provided. In a specific example, the magnetic poles of the second magnetic part 23 opposite to those of the plug 131 and the connecting surface of the third magnetic part 43 are opposite. When the interface connector 20 is inserted into the first plug-in position 411 in the forward direction, the third magnetic part 43 and the second magnetic part 23 move closer to each other and generate magnetic attraction, so that the connector base 21 of the interface connector 20 is quickly installed in the first plug-in position 411. At the same time, the second electrical connection part 22 located on the connector base 21 abuts against the third electrical connection part 42 located on the bottom wall of the first plug-in position 411 to achieve electrical connection. The plug 131 is external to the plug-in part 40 and is used to connect the electronic product to be charged. In another specific example, the magnetic poles of the second magnetic part 23 near the plug 131 are the same as those of the third magnetic part 43. When the interface connector 20 is inserted into the first insertion position 411 in reverse, the third magnetic part 43 and the second magnetic part 23 move closer to each other and generate a repulsive force. The connector base 21 is locked by the second latching part 241 located on the connector base 21 and the first latching part 441 located in the first insertion position 411. When the interface connector 20 is removed, the repulsive force helps to push the interface connector 20 to automatically pop out from the insertion part 40, making it easy for the user to remove the interface connector 20 from the insertion part 40.

[0154] It should be further explained that the first latching part 441 is located on the side wall of the first insertion position 411, and the second latching part 241 is located on the side wall of the connector base 21 at the position corresponding to the first latching part 441. When the interface connector 20 is inserted into the first insertion position 411 in the forward direction, the third magnetic attraction part 43 and the second magnetic attraction part 23 approach each other to generate a magnetic force. If the magnetic force is a magnetic attraction force, the connector base 21 can be quickly installed in the first insertion position 411. At the same time, the second electrical connection part 22 located on the connector base 21 abuts against the third electrical connection part 42 located on the bottom wall of the first insertion position 411 to achieve electrical connection. The second latching part 241 located on the connector base 21 engages with the first latching part 441 located in the first insertion position 411 to lock the connector base 21, preventing the interface connector 20 from being disconnected due to accidental pulling or squeezing during use.

[0155] To further explain, the third magnetic attraction part 43 and the second magnetic attraction part 23 approach each other to generate a magnetic force. If this magnetic force is a repulsive force, the interface connector 20 is installed in the plug-in part 40 by engaging the first latching part 441 and the second latching part 241. After the interface connector 20 is inserted into the first plug-in position 411 in reverse, the connector base 21 is locked by engaging the second latching part 241 on the connector base 21 with the first latching part 441 in the first plug-in position 411, so that the connector base 21 is securely installed in the first plug-in position 411. At this time, the second electrical connection part 22 on the connector base 21 faces away from the third electrical connection part 42 on the bottom wall of the first plug-in position 411, and the third electrical connection part 42 and the second electrical connection part 22 are disconnected. When the connector base 21 of the interface connector 20 is inserted into the first insertion position 411 in reverse, the corresponding plug 131 is inserted into the second insertion position 412. When the interface connector 20 is removed from the insertion part 40, the latching force between the first latching part 441 and the second latching part 241 is released. The repulsive force generated between the third magnetic part 43 and the second magnetic part 23 near the end of the plug 131 helps to push the interface connector 20 to automatically pop out from the insertion part 40, making it convenient for the user to remove the interface connector 20 from the insertion part 40.

[0156] Referring again to Figure 20, in some optional embodiments, the main body 12 is provided with an unlocking structure, which is connected to the first locking structure 44 so that the first locking structure 44 is released from the connection with the second locking structure 24. By operating the unlocking structure, the user can control the first locking structure 44 to move away from the second locking structure 24, thereby releasing the connection between the first locking structure 44 and the second locking structure 24.

[0157] Specifically, the unlocking structure includes an elastic element and a button 50. The elastic element is connected to both the first locking structure 44 and the button 50. Moving the button 50 causes the first locking structure 44 to extend and retract on the surface of the insertion portion 40. More specifically, the button 50 is connected to the first latching portion 441 via the elastic element. By operating the button 50, the user can control the first latching portion 441 to move away from the second latching portion 241, thereby releasing the locking force between the first latching portion 441 and the second latching portion 241. In this embodiment, through the setting of the button 50, the user can easily unlock the connection between the first latching portion 441 and the second latching portion 241. Especially when the connector base 21 of the interface connector 20 is inserted into the first insertion position 411 in reverse, when it is necessary to remove the interface connector 20 from the insertion part 40, the user can release the latching force between the first latching part 441 and the second latching part 241 by operating the button 50. At the same time, under the action of the repulsive force generated between the third magnetic part 43 and the second magnetic part 23, the interface connector 20 can be easily removed from the insertion part 40.

[0158] Referring to Figure 26, in some optional embodiments, the first latching part 441 is a protrusion, and the second latching part 241 is a recess, with the first latching part 441 and the second latching part 241 engaging in a convex-concave fit. In a specific example, the body 12 has an outer wall with a sliding groove. The button 50 is disposed in the sliding groove, and a sliding space is formed between the outer wall of the insertion part 40 and the outer wall of the body 12. The outer wall of the insertion part 40 has a through hole that matches the protrusion, allowing the protrusion to pass through the through hole when it slides to it. In actual use, the sliding of the button 50 can cause the protrusion to slide along the sliding space. When the protrusion slides to the position of the through hole, it can extend out of the sliding space, pass through the through hole, and abut against the recess on the interface connector 20, achieving a locking effect. When the protrusion slides away from the position of the through hole, it can retract into the sliding space and separate from the recess on the interface connector 20, achieving an unlocking effect.

[0159] In some optional embodiments, the number of plug-in portions 40 is at least two, and each plug-in portion 40 has a corresponding protrusion. Each protrusion has an independent button 50, meaning each protrusion has a corresponding button 50, allowing the user to individually control the locking and unlocking of the interface connector 20 within each plug-in portion 40. The user can select a specific plug-in portion 40 to operate as needed without affecting other plug-in portions 40. In some other optional embodiments, multiple protrusions share a single button 50, meaning one button 50 controls multiple protrusions simultaneously, providing the user with a quick and unified operation method. Furthermore, by providing multiple plug-in portions 40 on the body 12 of the portable charging device, this embodiment allows for the simultaneous installation of multiple different types of interface connectors 20, significantly enhancing the versatility and functionality of the portable charging device and meeting the diverse charging and connection needs of users.

[0160] [Sixth Embodiment]

[0161] Referring to Figures 27 to 29, the sixth embodiment of this application provides an interface connector 20. The interface connector 20 includes a connector base 21 and a plug 131 disposed on the connector base 21. The connector base 21 has a base wall 212 facing away from the plug 131, and a second electrical connection portion 22 is provided on the base wall 212. The plug 131 can be directly inserted into the charging interface of an electronic product to be charged, allowing the electronic product to be charged. The plug 131 has different types to adapt to various electronic products to be charged, such as smartphones and tablets. The connector base 21 of the interface connector 20 is typically electrically connected to a charging device. Specifically, the interface connector 20 achieves electrical connection with the charging device through the second electrical connection portion 22, enabling the current from the charging device to be transmitted to the electronic product to be charged.

[0162] In this embodiment, the interface connector 20 has a plug 131 on the connector base 21 and a second electrical connection part 22 on the bottom wall 212 of the base opposite to the plug 131. Its structure is simple, and users can connect different types of interface connectors 20 to charging devices (such as power banks or chargers) via the second electrical connection part 22 as needed, thereby improving the versatility and compatibility of the charging devices. Furthermore, when the interface connector 20 malfunctions or is damaged and needs to be replaced, it can be removed from the charging device.

[0163] In some optional embodiments, the second electrical connection portion 22 is located in the middle region of the bottom wall 212 of the base. In a specific embodiment, the plug 131 is located at the position corresponding to the second electrical connection portion 22 on the connector base 21, that is, the plug 131 is located in the middle region of the connector base 21 on the side away from the second electrical connection portion 22, so that the second electrical connection portion 22 is more stably connected to the corresponding electrical connection device.

[0164] In some alternative embodiments, the connector base 21 is further provided with a locking component 401. The locking component 401 enables the connector base 21 to achieve a secure mechanical connection with the charging device while maintaining an electrical connection, and allows for easy disassembly, so that the interface connector 20 can be securely connected to the charging device during use.

[0165] In some alternative embodiments, the locking component 401 includes a second magnetic part 23, the connector base 21 has a base top wall 213 near the plug 131, and the second magnetic part 23 is disposed on the base bottom wall 212 and / or the base top wall 213.

[0166] In one specific embodiment, the second magnetic attraction part 23 includes a first magnetic attraction body 231, which is disposed within the connector base 21 and exposed on the bottom wall 212 of the base. One first magnetic attraction body 231 may be provided, and its magnetic attraction force is sufficiently large to magnetically attract the corresponding magnetic component of the external charging device, thereby ensuring a stable connection between the connector base 21 and the charging device. Specifically, two first magnetic attraction bodies 231 may be provided, respectively located at opposite ends of the second electrical connection part 22. The two first magnetic attraction bodies 231 may be symmetrically arranged about the second electrical connection part 22 and located at both ends of the connector base 21, which can make the connection between the first magnetic attraction body 231 and the charging device more stable.

[0167] In another specific embodiment, the second magnetic attraction portion 23 includes a second magnetic attraction body 232, which is disposed within the connector base 21 and exposed on the top wall 213 of the base. Specifically, the first magnetic attraction body 231 and the second magnetic attraction body 232 are arranged collinearly in the height direction of the interface connector 20, so that the first magnetic attraction body 231 and the second magnetic attraction body 232 can be directly aligned with the same third magnetic attraction portion 43 of the charging device. More specifically, there are two second magnetic attraction bodies 232, respectively located at opposite ends of the plug 131 corresponding to the first magnetic attraction body 231.

[0168] It should be noted that the first magnetic 231 and the second magnetic 232 are disposed on the top wall 213 and / or the bottom wall 212 of the connector base 21, so that the interface connector 20 has a positive and an inverted state. In the positive state, the first magnetic 231 is connected to the third magnetic part 43 of the charging device, and the plug 131 is exposed outside the charging device; in the inverted state, the second magnetic 232 is connected to the third magnetic part 43 of the charging device, and the plug 131 is housed inside the charging device.

[0169] In some optional embodiments, the locking component 401 includes a second latching portion 241 disposed on the connector base 21. The second latching portion 241 provides a locking force for mounting the interface connector 20 onto the charging device. In one specific embodiment, the connector base 21 has a base top wall 213 opposite to the base bottom wall 212, and a base side wall 214 located between the base bottom wall 212 and the base top wall 213, with the second latching portion 241 disposed on the base side wall 214. The second latching portion 241 securely mounts the connector base 21 onto the charging device, preventing the interface connector 20 from being disconnected due to accidental pulling or squeezing during use. However, in some cases, such as when the magnetic attraction force of the magnetic component is large, the second latching portion 241 may not be provided. Because the magnetic attraction force itself can provide sufficient fixing force, the interface connector 20 can be securely connected to the charging device without additional locking force. This design simplifies the connection structure and improves assembly efficiency.

[0170] In some optional embodiments, the second electrical connection 22 includes multiple pin contacts or multiple metal plate contacts. Specifically, the second electrical connection 22 can be a pin in a Pogo Pin connector or a metal plate that matches the pin, which has a simple structure, is easy to assemble, and has high reliability.

[0171] Furthermore, referring to Figures 30 to 32, this embodiment also provides a portable power bank, which includes a body 12 and an interface connector 20 as described in any of the above embodiments. The body 12 is provided with a charging circuit and a plug-in portion 40. The interface connector 20 is detachably connected to the body 12. The plug-in portion 40 is provided with a third electrical connection portion 42. When the second electrical connection portion 22 on the connector base 21 is electrically connected to the third electrical connection portion 42, the third electrical connection portion 42 electrically connects the corresponding interface connector 20 to the charging circuit. When the second electrical connection portion 22 is a pin contact, the third electrical connection portion 42 is a metal plate contact; when the second electrical connection portion 22 is a metal plate contact, the third electrical connection portion 42 is a pin contact. The pin contact and the metal plate contact abut against each other to achieve electrical connection between the portable power bank body 12 and the interface connector 20.

[0172] In this embodiment, the power bank is equipped with an interface connector 20 as described in any of the above embodiments. The interface connector 20 is detachably connected to the main body 12. The insertion portion 40 of the main body 12 is provided with a third electrical connection portion 42. When the second electrical connection portion 22 and the third electrical connection portion 42 are electrically connected, the corresponding interface connector 20 is electrically connected to the charging circuit. This allows the main body 12 of the power bank to be detachably connected to the interface connector 20. Users can replace the interface connector 20 with one suitable for their electronic products, improving the compatibility and versatility of the power bank. It should be noted that detachable connection means that it does not require forced disassembly; the two components remain intact after disassembly. For example, the interface connector 20 and the main body 12 of the power bank are independent components. The interface connector 20 can be connected to the main body 12 of the power bank or simply removed from the main body 12. After removal, the interface connector 20 remains intact.

[0173] In some alternative embodiments, multiple interface connectors 20 are provided, and the plugs 131 of the interface connectors 20 are of different types, each supporting different interface standards. Multiple plug-in portions 40 are provided, and each plug-in portion 40 corresponds one-to-one with an interface connector 20.
