Referring to fig. 3 to 5, fig. 3 is a schematic view illustrating a connection structure of the pin 100 and the housing 200 in fig. 2, fig. 4 is a schematic view illustrating a cross-sectional structure of the pin 100 and the housing 200 along v-v in fig. 3, and fig. 5 is an enlarged view of a portion a in fig. 3.

The housing 200 may be used to mount and protect various components required by the power adapter 10. As shown in fig. 3 to 4, the housing 200 may be provided with a receiving cavity 201 for mounting the circuit board 500, and the receiving cavity 201 may be used for mounting other components required for the power adapter 10 in addition to the circuit board 500. Meanwhile, the case 200 may further include: a case 210 and a case cover 220. Wherein, the box body 210 may be similar to a hollow rectangular parallelepiped structure in appearance. The cover 220 may be covered on the case body 210 from the side of the opening of the case body 210, and together with the case body 210, forms the accommodating cavity 201. The case 200 is designed to be divided into the case body 210 and the case cover 220, so that the circuit board 500 can be easily assembled with the case 200. Alternatively, the case 210 and the case cover 220 may be connected by, for example, clamping, bonding, welding, and screwing.

The receiving groove 202 can be used for installing the shaft 300 and providing a clearance space required for connecting the cover 400 and the shaft 300, so as to maintain the flatness of the outer surface of the power adapter 10 and prevent the shaft 300 and the cover 400 from forming a protrusion on the outer surface of the box 210. Alternatively, the rotation shafts 300 may be directly disposed at opposite sides of the case 210, and the design of the receiving groove 202 may be eliminated.

Further, the positioning portions 212 may be disposed in the receiving grooves 202 on two opposite sides. As shown in fig. 3 to 5, the positioning portion 212 may be located on an inner sidewall of the receiving groove 202 contacting the first surface 211, and may be engaged with the cover 400 to limit the cover 400 from being turned over to reside the cover 400 when the cover 400 receives the pin 100, so as to maintain the receiving state of the pin 100 by the cover 400, and improve the portability and safety of the power adapter 10 during carrying. Meanwhile, the positioning portion 212 may be an integral structure with the case 210, which may be formed by protruding a partial region of the case 210 within the receiving groove 202. In this way, the positioning portion 212 can be directly formed in the process of manufacturing the box 210, which is beneficial to simplifying the assembling process of the power adapter 10.

In order to connect the patch cord with the power adapter 10, the box cover 220 may further be provided with a notch 203 communicating with the accommodating cavity 201, so that the patch cord can be electrically connected with an interface integrated on the circuit board 500 through the notch 203. Any one or more combinations of charging interfaces such as a micro-usb interface, a type-c interface, and a lightning interface may be integrated on the circuit board 500, so that the power adapter 10 may be electrically connected to the electronic device through a patch cord corresponding to the interface. Alternatively, the notch 203 may not be limited to be disposed on the box cover 220, but may be disposed on the box body 210, and only the charging interface may correspond to the notch 203.

Referring to fig. 6 to 7, fig. 6 is a schematic view of a connection structure of the pin 100, the housing 200 and the shaft 300 in fig. 2, and fig. 7 is a schematic view of a partial cross-sectional structure of the pin 100, the housing 200 and the shaft 300 in fig. 6 along vi-vi.

The hinge 300 may be used to realize the hinge connection between the housing 200 and the cover 400, so that the cover 400 can be turned over relative to the housing 200 to accommodate the pins 100, thereby improving the portability and safety of the power adapter 10 during carrying. As shown in fig. 6 to 7, the rotation shaft 300 may include: a first shaft 310 and a second shaft 320. The first rotating shaft 310 may be disposed in the accommodating groove 202 on one side of the box body 210, and the first rotating shaft 310 may be located on an inner sidewall of the accommodating groove 202 connected to the first surface 211 and disposed adjacent to the positioning portion 212. The second shaft 320 can be disposed in the receiving groove 202 on the other opposite side of the box body 210, and the second shaft 320 can also be disposed on the inner sidewall of the receiving groove 202 connected to the first surface 211 and adjacent to the positioning portion 212. Meanwhile, the first rotating shaft 310 and the second rotating shaft 320 may be disposed opposite to each other to maintain the turning consistency of the cover 400 with respect to the case 210 through the first rotating shaft 310 and the second rotating shaft 320. Thus, the rotating shaft 300 is provided as the first rotating shaft 310 and the second rotating shaft 320, and the first rotating shaft 310 and the second rotating shaft 320 can be respectively located in the accommodating grooves 202 on two opposite sides, so that the pin 100 in the accommodating cavity 201 can be avoided, and the situation that the pin 100 is blocked by the accommodating cavity 201 and electrically connected with the circuit board 500 after the first rotating shaft 310 and the second rotating shaft 320 are connected into a whole is avoided.

Further, one end of the first rotating shaft 310 may be located in the accommodating chamber 201 and fixed to an inner wall of the accommodating chamber 201. One end of the second rotating shaft 320 may also be located in the accommodating cavity 201 and fixed on the inner wall of the accommodating cavity 201. Meanwhile, the housing 200 may be further provided with a fixing member 230 for limiting the displacement of the first and second rotating shafts 310 and 320. As shown in fig. 6 to 7, the fixing member 230 may be disposed in the accommodating cavity 201, and two opposite sides of the fixing member 230 may be respectively abutted against one ends of the first rotating shaft 310 and the second rotating shaft 320 located in the accommodating cavity 201, so as to support and limit the first rotating shaft 310 and the second rotating shaft 320, and reduce the probability of displacement of the first rotating shaft 310 and the second rotating shaft 320 under the action of an external force. In addition, in order to facilitate fixing the fixing member 230 in the accommodating cavity 201, the fixing member 230 may be attached to the inner wall of the accommodating cavity 201. Thus, in the assembling process, the fixing member 230 is only required to be installed in the accommodating cavity 201, so that the fixing member 230 can be abutted against the inner wall of the accommodating cavity 201 to complete the assembling.

The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Referring to fig. 8 to 10 in combination with fig. 1, fig. 8 is another schematic structural diagram of the power adapter 10 in fig. 1, fig. 9 is a schematic structural diagram of the first cover 410 in fig. 8, and fig. 10 is a schematic structural diagram of the second cover 420 in fig. 8.

The cover 400 may be hinged to the case 210 by the hinge 300, and may receive the pin 100 after being turned over with respect to the case 210, so as to improve portability and safety of the power adapter 10 when being carried. As shown in fig. 1 and 8, the cover 400 may receive the pins 100 when the cover 400 is turned to the first position, and the pins 100 may be connected to the socket when the cover 400 is turned to the second position. In this way, when the user needs to use the power adapter 10, the cover 400 may be turned to the second position, so that the pins 100 can be connected to the socket. When a user needs to carry the power adapter 10, the cover 400 may be turned to the first position, so that the pins 100 can be covered and hidden by the cover 400 to improve portability and carrying safety of the power adapter 10. The first position and the second position can be adjusted according to design requirements, and only the cover 400 needs to be ensured to accommodate the pin 100 at the first position, and the connection between the pin 100 and the socket is not affected at the second position.

Specifically, the cover 400 may include: a first cover 410 and a second cover 420. The first cover 410 can be simultaneously sleeved on the first rotating shaft 310 and the second rotating shaft 320, and the second cover 420 can also be simultaneously sleeved on the first rotating shaft 310 and the second rotating shaft 320. When the first cover 410 and the second cover 420 are turned to the first position, the two covers can be respectively located at two opposite sides of the pin 100, and together enclose to form the receiving space 401, so that the pin 100 is received by the receiving space 401, and the pin 100 is covered and hidden. Accordingly, when the first cover 410 and the second cover 420 are turned to the second position, they can be unfolded toward the opposite sides of the pins 100, so that the pins 100 are exposed, thereby facilitating the connection of the pins 100 with the socket. Alternatively, the cover 400 may be provided with only the first cover 410, and the first cover 410 may be provided with a receiving space 401 for receiving the pin 100, so that the pin 100 is received by the receiving space 401 after the first cover 410 is turned to the first position, and the first cover 410 and the second cover 420 together enclose the receiving space 401.

In order to make the first cover 410 and the second cover 420 reside at the first position and the second position, the first cover 410 and the second cover 420 may be further disposed on the first rotating shaft 310 and the second rotating shaft 320 in a crossed manner, so that both the first cover 410 and the second cover 420 can be engaged with the positioning portion 212 in the receiving groove 202. As shown in fig. 8 to 10, the first cover 410 may be provided with a first connecting portion 411 and a first mating portion 412, and the first connecting portion 411 and the first mating portion 412 may be disposed opposite and spaced apart from each other. The first connecting portion 411 may be sleeved on the first rotating shaft 310, the first engaging portion 412 may be sleeved on the second rotating shaft 320, and the first connecting portion 411 may be provided with a first positioning groove 4001 and a second positioning groove 4002 engaged with the positioning portion 212. When the first cover 410 is turned to the first position, the positioning portion 212 may occupy the first positioning groove 4001 to limit the turning of the first cover 410, so as to realize the residence of the first cover 410 in the first position. When the first cover 410 is turned to the second position, the positioning portion 212 may occupy the second positioning groove 4002 to limit the turning of the first cover 410, so as to realize the residence of the first cover 410 at the second position.

Accordingly, the second cover body 420 may be provided with a second connection portion 421 and a second fitting portion 422, and the second connection portion 421 and the second fitting portion 422 may be oppositely and spaced apart. The second connecting portion 421 can be sleeved on the second shaft 320 and located between the box 210 and the first matching portion 412, and the second connecting portion 421 can also be provided with a first positioning groove 4001 and a second positioning groove 4002 matched with the positioning portion 212. The second matching portion 422 can be sleeved on the first rotating shaft 310 and is located on a side of the first connecting portion 411 departing from the box 210. When the second cover 420 is turned to the first position, the positioning portion 212 may occupy the first positioning groove 4001 to limit the turning of the second cover 420, so as to realize the residence of the second cover 420 in the first position. When the second cover 420 is turned to the second position, the positioning portion 212 may occupy the second positioning groove 4002 to limit the turning of the second cover 420, so as to enable the second cover 420 to reside at the second position.

Further, in order to realize that the first cover 410 and the second cover 420 can reside at other positions between the first position and the second position, the first connecting portion 411 and the second connecting portion 421 may be provided with a third positioning groove 4003. The third positioning slot 4003 may be located on a moving path of the positioning portion 212 from the first positioning slot 4001 to the second positioning slot 4002, so that the positioning portion 212 may occupy the third positioning slot 4003 when the first cover 410 and/or the second cover 420 are turned from the first position to the second position, so as to limit turning of the first cover 410 and/or the second cover 420, and thus to realize residence of the first cover 410 and/or the second cover 420 at other positions between the first position and the second position.

Alternatively, the third positioning groove 4003 may be provided on other moving paths of the positioning portion 212, except for being disposed between the first positioning groove 4001 and the second positioning groove 4002, and only the positioning portion 212 needs to occupy the third positioning groove 4003 during the movement. In addition, the first connection portion 411 and the second connection portion 421 may also be provided with only the first positioning groove 4001 to realize the residence of the first cover 410 and the second cover 420 at the first position.

By sleeving the first cover 410 and the second cover 420 on the first rotating shaft 310 and the second rotating shaft 320 in a crossed manner, both the first cover 410 and the second cover 420 can be matched with the positioning portion 212 in the accommodating groove 202, so that the first cover 410 and the second cover 420 can be retained at the first position and the second position. Compared with the scheme of utilizing magnetic attraction or a torsion spring to realize the residence of the cover 400, the power adapter 10 provided by the embodiment of the application has a simpler overall structure, and is beneficial to simplifying the assembly process of the power adapter 10 and reducing the production cost of the power adapter 10.

Alternatively, besides the first positioning groove 4001, the second positioning groove 4002 and the third positioning groove 4003, the first connecting portion 411 and the second connecting portion 421 may be provided with a plurality of positioning grooves, such as four, five, six or more positioning grooves, as required, so as to realize the residence of the first cover 410 and the second cover 420 at different positions. In addition, it is understood that the names of the first positioning slot, the second positioning slot, the third positioning slot, and the positioning slot may be interchanged. For example, in some embodiments, a "first detent" may be referred to as a "second detent" or "detent" and a "second detent" may also be referred to as a "first detent" or "detent".

Optionally, the positions of the positioning portion 212 and the positioning groove may be interchanged, that is, the positioning portion 212 may be disposed on each of the first connecting portion 411 and the second connecting portion 421 facing the cartridge 210, and the positioning groove matched with the positioning portion 212 may be disposed on the inner sidewall of the receiving groove 202 connected to the first surface 211. In this way, the first cover 410 and the second cover 420 can still reside at the first position and the second position by using the positioning portion 212 and the positioning groove.

Alternatively, the first cover 410 and the second cover 420 may be engaged with each other to reside at different positions, except for the positioning portion 212 on the case 210. For example, a side of the first coupling portion 411 facing the second fitting portion 422 may be provided with one of the positioning portion 212 and the positioning groove, and a side of the second fitting portion 422 facing the first coupling portion 411 may be provided with the other of the positioning portion 212 and the positioning groove. Accordingly, the second connecting portion 421 and the first mating portion 412 may be arranged in the same manner. In this way, when the first cover 410 and the second cover 420 are turned over, the positioning portion 212 can still occupy the positioning groove to limit the turning over of the first cover 410 and the second cover 420.

As shown in fig. 9 to 10, since the first cover 410 and the second cover 420 are both sleeved on the first rotating shaft 310 and the second rotating shaft 320, in order to avoid mutual interference when the two are turned over, a first avoiding groove 4004 may be disposed on a side of the first connecting portion 411 away from the box 210, and the second matching portion 422 may be disposed in the first avoiding groove 4004. Correspondingly, a second avoiding groove 4005 may also be disposed on a side of the second connecting portion 421 away from the case 210, and the first matching portion 412 may be disposed in the second avoiding groove 4005. When the first cover body 410 and the second cover body 420 are turned to the first position, the first engaging portion 412 may completely occupy the second avoiding groove 4005 to fill the second avoiding groove 4005, and the second engaging portion 422 may also completely occupy the first avoiding groove 4004 to fill the first avoiding groove 4004. So configured, it is beneficial to improve the flatness of the outer surface of the power adapter 10.

Referring to fig. 11 to 13 in conjunction with fig. 8, fig. 11 is a partial sectional view of the power adapter 10 of fig. 1 taken along line iv-iv, fig. 12 is a partial sectional view of the power adapter 10 of fig. 8 taken along line vii-vii, and fig. 13 is a partial sectional view of the power adapter 10 of fig. 8 taken along line ix-ix.

As shown in fig. 8 and 11 to 12, in order to prevent the first cover 410 and the second cover 420 from interfering with the pin 100 when the pin 100 is connected to the socket, the first cover 410 may further be provided with a second surface 413, and the second cover 420 may further be provided with a third surface 423. When the first cover 410 and the second cover 420 are turned to the first position, the second surface 413 may contact the second cover 420, the third surface 423 may contact the first cover 410, and the second surface 413 and the third surface 423 may form an included angle. When the first cover 410 and the second cover 420 are turned to the second position, the second surface 413 and the third surface 423 may be parallel to the first surface 211, and may form a contact surface 402 together, and the contact surface 402 may contact with an outer surface of the socket when the pin 100 and the socket are connected. Meanwhile, in order to completely submerge the pin 100 into the socket of the socket, the second surface 413 and the third surface 423 may be disposed flush with the first surface 211, or may be disposed slightly lower than the first surface 211, so as to ensure that the first surface 211 can contact with the outer surface of the socket after the pin 100 is connected to the socket. In addition, as shown in fig. 8 and 12, in order to meet the national standard requirements, the distances L1 and L2 between the pins 100 and the edge of the contact surface 402 may also be greater than or equal to 6.5mm to improve the safety of the power adapter 10 in use.
