[0025] Reference Figures 1 to 5 A plug-convertible charger according to an embodiment of this application includes a charging unit 100 and a conversion unit 200.

[0026] The charging unit 100 includes a first plug 110; the conversion unit 200 includes a second housing 210, a second plug 220, a limiting member 230, and a power receiving member 240; the second plug 220 is disposed in the second housing 210 and is connected to the power receiving member 240; the second housing 210 forms a socket 211; the limiting member 230 is swayably disposed in the second housing 210, and the limiting member 230 is provided with a limiting hole 231, which is located between the socket 211 and the power receiving member 240; the first plug 110 can pass through the socket 211 and the limiting hole 231 in sequence to contact the power receiving member 240; the limiting member 230 can lock or unlock the first plug 110 that passes through the limiting hole 231.

[0027] Understandably, referring to Figure 1 The first plug 110 and the second plug 220 are plugs of different specifications to adapt to different sockets. When needing to connect to a socket compatible with the first plug 110, the charging unit 100 can be used independently. The charging unit 100 is used for electrical connection to electrical devices, such as mobile phones and tablets. The first plug 110 is directly plugged into its compatible socket to supply power to the device. When needing to connect to a socket compatible with the second plug 220, refer to... Figure 3 The first plug 110 can be inserted into the second housing 210 through the socket 211 on the second housing 210. At this time, the limiting member 230 is in an inclined state, that is, the orientation of the limiting hole 231 on the limiting member 230 intersects with the insertion direction of the first plug 110. (Refer to...) Figure 4 The first plug 110 passes through the limiting hole 231, abutting against the inner wall of the limiting hole 231 to push the limiting member 230 to swing to a horizontal state. This means the orientation of the limiting hole 231 on the limiting member 230 is the same as the insertion direction of the first plug 110, facilitating its passage through the limiting hole 231. After passing through the limiting hole 231, the first plug 110 contacts the connecting member 240, which then electrically connects it to the second plug 220. The second plug 220, when inserted into the socket, provides power to the device connected to the first plug 110, thus adapting to different sockets. Furthermore, referring to… Figure 5 After the first plug 110 is inserted and abuts against the connector 240, the limiting member 230 swings to an inclined state, locking the first plug 110 and making it difficult for the first plug 110 to move relative to the limiting hole 231, thus making it difficult to pull out the first plug 110 and ensuring the contact stability between the first plug 110 and the connector 240. When it is necessary to pull the first plug 110 out of the second housing 210, the limiting member 230 swings to a horizontal state, unlocking the first plug 110 and facilitating its passage through the limiting hole 231 so that the first plug 110 can be pulled out.

[0028] In summary, the first plug 110 can be inserted into the second housing 210 and electrically connected to the second plug 220 via the connector 240, allowing for switching between using either the first plug 110 or the second plug 220 to connect to the socket. The first plug 110 and the second plug 220 can be adapted to different sockets, thus enabling the plug-convertible charger of this application to be compatible with various sockets. Furthermore, the first plug 110 passes through the limiting hole 231 of the limiting member 230. When the limiting member 230 is horizontal, it facilitates the first plug 110 passing through the limiting hole 231, allowing it to contact the connector 240 and subsequently unlock the first plug 110. When the limiting member 230 is tilted, it locks the first plug 110 through the limiting hole 231, preventing it from being easily pulled out and ensuring stable contact between the first plug 110 and the connector 240.

[0029] Specifically, the connector 240 is a metal sheet, one end of the second plug 220 protrudes from the second housing 210 for connecting to an external socket, and the other end of the second plug 220 passes through the second housing 210 and connects to the connector 240.

[0030] Specifically, the limiting member 230 is a limiting block, which is roughly square in shape, and the cross-section of the limiting hole 231 is also square, so that the first plug 110 can be locked when the limiting member 230 is in an inclined state.

[0031] Reference Figures 2 to 5 According to some embodiments of this application, the conversion part 200 further includes a first elastic member 250 and a fixing member 260. The fixing member 260 is disposed in the second housing 210 and is provided with a first slot 261. One end of the limiting member 230 is swayably engaged in the first slot 261, and the other end of the limiting member 230 is connected to the first elastic member 250. The first elastic member 250 is used to provide the limiting member 230 with an elastic force to keep the first plug 110 locked.

[0032] Understandably, when the first plug 110 is not inserted into the second housing 210, the first elastic member 250 provides elastic force to the other end of the limiting member 230, causing the limiting member 230 to be in an inclined state. The two ends of the limiting member 230 are relatively inclined, and the end of the limiting member 230 connected to the first elastic member 250 is closer to the socket 211 than the end that is engaged in the first slot 261. When the first plug 110 is inserted into the second housing 210 and pushes the limiting member 230 to swing, the limiting member 230 pushes the first elastic member 250 to compress, causing the limiting member 230 to be in a horizontal state. The two ends of the limiting member 230 are relatively horizontal, which facilitates the first plug 110 passing through the limiting hole 231. After the first plug 110 contacts the power receiving component 240, the pushing force on the first plug 110 is released, the retracted first elastic member 250 extends, and the first elastic member 250 provides elastic force to the limiting member 230, causing the limiting member 230 to swing to an inclined state. The inner wall of the limiting hole 231 abuts against the outer side of the first plug 110, locking the first plug 110, thereby realizing that the limiting member 230 automatically locks the first plug 110.

[0033] Specifically, the fixing member 260 is a fixing block. The first plug 110 can pass between the movable member 270 and the fixing member 260 to pass through the limiting member 230 between the fixing member 260 and the movable member 270.

[0034] In other embodiments, regarding the swinging mode of the limiting member 230, the limiting member 230 may also partially extend through the second housing 210, and the portion of the limiting member 230 extending through the second housing 210 may be moved to make the limiting member 230 swing.

[0035] Reference Figures 2 to 5According to some embodiments of this application, the conversion part 200 further includes a movable member 270, which is provided with a second slot 271. The other end of the limiting member 230 is swayably engaged in the second slot 271. The first elastic member 250 is connected to the movable member 270. The first slot 261 and the second slot 271 can be opposite to each other or offset from each other.

[0036] Understandably, the first elastic member 250 is connected to the limiting member 230 via the movable member 270. When the first plug 110 is not inserted into the second housing 210, the movable member 270 is pushed against the inner wall of the second housing 210 where the insertion port 211 is located, under the elastic force of the first elastic member 250. At this time, the second slot 271 and the first slot 261 are misaligned, and the limiting member 230 is in an inclined state. When the first plug 110 is inserted into the second housing 210 and pushes the limiting member 230 to swing, the end of the limiting member 230 that is engaged in the second slot 271 pushes the movable member 270 to compress the first elastic member 250 until the first slot 261 and the second slot 271 are aligned. At this time, the limiting member 230 is in a horizontal state. After the first plug 110 contacts the power receiving part 240, the pushing force on the first plug 110 is released, the retracted first elastic member 250 extends, the first elastic member 250 gives the movable part 270 an elastic force, the second slot 271 and the first slot 261 are misaligned again, the limiting member 230 is in an inclined state, and the first plug 110 is locked.

[0037] Reference Figure 2 and Figure 6 According to some embodiments of this application, the conversion unit 200 further includes a switch 280, which is movably disposed in the second housing 210. The switch 280 is connected to the movable member 270 and is used to drive the second slot 271 of the movable member 270 to move relative to the first slot 261 of the fixed member 260.

[0038] Understandably, switch 280 can drive movable member 270 to translate, causing movable member 270 to compress first elastic member 250, thereby aligning the second slot 271 of movable member 270 with the first slot 261 of fixed member 260, thus driving limiting member 230 to swing from an inclined state to a horizontal state. Therefore, when it is necessary to remove the first plug 110 from the second housing 210, switch 280 can drive limiting member 230 to swing to a horizontal state, unlocking the first plug 110, making it easy to remove. Alternatively, it can be understood that when it is necessary to insert the first plug 110 into the second housing 210, switch 280 can first drive movable member 270 to swing to a horizontal state, facilitating the first plug 110 to pass through limiting member 230.

[0039] Reference Figure 1 and Figure 6According to some embodiments of this application, the movable member 270 is provided with a slope 272, and the switch 280 protrudes out of the second housing 210 and forms a pressing protrusion 281. The pressing protrusion 281 is used to receive force to push the switch 280 into the second housing 210, and one end of the switch 280 slides in cooperation with the slope 272.

[0040] It is understood that the switch 280 is a push-button switch 280, which can be pressed to insert the switch 280 into the second housing 210. During the insertion of the movable member 270, the movable member 270 abuts against and slides against the inclined surface 272, and the inclined surface 272 pushes the movable member 270 to move, so that the limiting member 230 swings from the inclined state to the horizontal state.

[0041] In other embodiments, the switch 280 may also be a sliding switch 280, which is fixedly connected to the movable member 270 and can move along the direction in which the movable member 270 compresses the first elastic member 250.

[0042] Reference Figure 6 According to some embodiments of this application, the switching unit 200 further includes a second elastic member 290, which is connected to the switch 280 and is used to give the switch 280 an elastic force to exit the second housing 210.

[0043] Understandably, after pressing the switch 280 to unlock the first plug 110 and pull out the plug by the limit member 230, the pressure on the switch 280 is released, and the switch 280 is reset under the elastic force of the second elastic member 290. After the switch 280 is reset, the movable member 270 is reset under the action of the first elastic member 250.

[0044] Reference Figure 1 According to some embodiments of this application, a pressing protrusion 281 is provided on the side end of the second housing 210.

[0045] It is understandable that the pressing protrusion 281 passes through the side end of the second housing 210, that is, the end face of the pressing protrusion 281 is not the same as the end face of the second plug 220 and the end face of the socket 211, which makes it easier to press the switch 280, that is, to unlock the limiting member 230. Specifically, the end face of the second plug 220 is opposite to the end face of the socket 211.

[0046] Reference Figure 2 and Figure 3 According to some embodiments of this application, the fixing member 260 has a first channel 262, the first channel 262 can be inserted into the first plug 110, and the two ends of the first channel 262 face the limiting member 230 and the power receiving member 240.

[0047] It is understandable that after the first plug 110 passes through the limiting hole 231 of the limiting member 230, the first plug 110 will pass into the first channel 262. After the first plug 110 passes through the first channel 262, it will contact the power receiving member 240. Thus, the first channel 262 plays a guiding role in the insertion of the first plug 110.

[0048] Reference Figure 2 and Figure 3 According to some embodiments of this application, the fixing member 260 has a second channel 263, and the movable member 270 is movably disposed within the second channel 263.

[0049] It is understandable that when the movable member 270 is compressed by the first elastic member 250 or is pushed by the first elastic member 250, it moves within the second channel 263. Thus, the second channel 263 guides the movement of the movable member 270. Specifically, the portion of the movable member 270 with the second slot 271 protrudes from the second channel 263 to ensure that the second slot 271 can engage with the limiting member 230.

[0050] In some other embodiments, a through hole may be made on the wall of the second channel 263 to allow the second slot 271 to protrude through the through hole.

[0051] According to some embodiments of this application, the charging unit 100 further includes a first housing 120, the first housing 120 being provided with a receiving groove 121, and a first plug 110 being rotatably disposed in the first housing 120 and rotatably inserted into the receiving groove 121.

[0052] It is understood that the first plug 110 can rotate relative to the first housing 120 and can rotate into the receiving slot 121 so as to store the first plug 110 when not in use, reduce the space occupied by the charging unit 100, and make it easy to carry.

[0053] In one specific embodiment, reference is made to... Figures 2 to 6The second housing 210 has two first plugs 110, two sockets 211 on the back, and three second plugs 220 on the front. Two electrical connectors 240 are also provided on the inner wall of the second housing 210 corresponding to the front. One fixing member 260 is located inside the second housing 210. A second channel 263 is formed in the middle of the fixing member 260. First channels 262 are formed on both sides of the second channel 263, corresponding one-to-one with the two sockets 211. A first slot 261 is formed on the side of the fixing member 260 corresponding to each of the two first channels 262 near the sockets 211. A movable member 270 is located within the second channel 263 in the middle of the fixing member 260, and the portion of the movable member 270 forming the second slot 271 protrudes from the second channel 263. Two limiting members 230 are respectively provided corresponding to the two first channels 262 and the two sockets 211, that is, the limiting members 230 are located between the first channels 262 and the sockets 211, and the two ends of the limiting members 230 are respectively locked in the first slot 261 of the fixing member 260 and the second slot 271 of the movable member 270. One first elastic member 250 is provided, and the first elastic member 250 is connected to the side of the movable member 270 away from the back of the second housing 210, so that the movable member 270 tends to move closer to the back of the second housing 210. The switch 280 passes through the periphery of the second housing 210, and the pressing direction of the switch 280 is perpendicular to the insertion direction of the first plug 110 into the second housing 210. The side of the movable member 270 near the back of the second housing 210 forms an inclined surface 272. The switch 280 slides with the inclined surface 272 so that it can push the inclined surface 272 to move the movable member 270 away from the back of the second housing 210, thereby compressing the first elastic member 250. The second elastic element 290 connects the switch 280 and the fixing element 260 to push the switch 280 to reset.

[0054] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
