DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0034] The present application provides a power adapter 10 (Power adapter). Figure 1 , Figure 1A schematic diagram of the application environment of a power adapter provided for one embodiment of the present application. The so-called power adapter 10 is a conversion device that provides power supply energy to the electronic device 30. Generally, the power adapter 10 can convert AC voltage into DC voltage. For example, the power adapter 10 is plugged into the socket 50, receives the AC voltage output by the socket 50, and converts the received AC voltage into DC voltage, and the DC voltage is used to charge the electronic devices 30 such as mobile phones and computers that use electricity. It is understandable that in other embodiments, the power adapter 10 converts the received AC voltage into DC voltage, and the DC voltage is directly used for the electronic components in the electronic device 30. It is understandable that the schematic diagram of the application environment of the power adapter 10 only helps to understand the application of the power adapter 10, and should not be understood as a limitation of the power adapter 10 provided in this application.

[0035] Please also read Figure 2 , Figure 3 and Figure 4 , Figure 2 A schematic diagram of a power adapter provided in an embodiment of the present application in a first state;

[0036] Figure 3 for Figure 2 A schematic diagram showing a power adapter in a second state; Figure 4 for Figure 2 Schematic diagram of a three-dimensional decomposition of a power adapter in FIG. The power adapter 10 includes a housing assembly 100, a pin assembly 200, and a driving assembly 300. The housing assembly 100 has a receiving space 1111 and a through hole 1312 communicating with the receiving space 1111. The pin assembly 200 includes a bearing seat 210 and a pin 220, wherein the bearing seat 210 is received in the receiving space 1111, and the pin 220 is supported on the bearing seat 210 and can move with the movement of the bearing seat 210. The driving assembly 300 is disposed in the receiving space 1111, and is used to control an electrical signal, and drive the pin assembly 200 to move under the control of the control electrical signal, so that the power adapter 10 has a first state in which the pin 220 is received in the receiving space 1111 and a second state in which the pin 220 is exposed from the housing assembly 100 through the through hole 1312.

[0037] The housing assembly 100 has a receiving space 1111, and the receiving space 1111 is used to receive the pin assembly 200, and the housing assembly 100 can also be used to receive and protect the components in the power adapter 10, such as the circuit board 400, the battery 700, etc. The shape of the housing assembly 100 can be, but is not limited to, a cylindrical shape, an elliptical cylindrical shape, a cube, a cube, etc. In this embodiment, the outer shape of the housing assembly 100 is similar to a cylindrical shape as an example for illustration. It can be understood that the outer shape of the housing assembly 100 should not be understood as a limitation on the power adapter 10 provided in this application. The extension direction of the housing assembly 100 is a preset extension direction. The through hole 1312 on the housing assembly 100 is used for the pin 220 to extend or retract into the receiving space 1111. The number of the through holes 1312 is adapted to the number of the pins 220, so that all the pins 220 can extend out of the receiving space 1111 through the through holes 1312. In the schematic diagram of this embodiment, the number of the through holes 1312 is two as an example for illustration. In other embodiments, the number of the through holes 1312 may also be other numbers, such as three.

[0038] The material of the bearing seat 210 is an insulating material, such as plastic, rubber, plastic, ceramic, etc. The shape of the bearing seat 210 is adapted to the shape of the receiving space 1111 so as to be able to move in the receiving space 1111 .

[0039] The material of the pin 220 is metal, such as copper alloy, aluminum alloy, etc. The pin 220 is plugged into the socket 50 to receive the AC voltage provided by the socket 50. The number of the pins 220 can be, but is not limited to, two. In the schematic diagram of this embodiment, the number of the pins 220 is two as an example, and the two pins 220 are arranged oppositely and at intervals. In other embodiments, the number of the pins 220 is three. The pins 220 can be, but is not limited to, long strips. The end of the pin 220 away from the body of the socket 50 is arc-shaped to facilitate the insertion of the pin 220 into the socket 50. The bearing seat 210 and the pin 220 can be fixed together by, but is not limited to, integral injection molding. The pin 220 is exposed on the end surface 1311 of the bearing seat 210 close to the through hole 1312. In this embodiment, the movement direction of the pin 220 is the same as the movement direction of the bearing seat 210.

[0040] The driving assembly 300 is disposed in the receiving space 1111, and is used to receive a control electrical signal, and drive the pin assembly 200 to move under the control of the control electrical signal. In this embodiment, the power adapter 10 has a button 900, and the button 900 is disposed on the housing assembly 100. The button 900 receives user operation and triggers the control signal. The following describes a detailed process in which the button 900 receives a user operation to trigger the control signal and the control signal drives the pin 220 to move.

[0041] When the pin 220 is in the first state of being accommodated in the accommodation space 1111, when the button 900 receives an operation from a user, a first control signal is triggered to be generated, and the first control signal is used to drive the bearing seat 210 to move, and the bearing seat 210 moves and drives the pin 220 to be exposed in the housing assembly 100 through the through hole 1312. In this embodiment, the first control signal drives the bearing seat 210 to move toward the through hole 1312 as an example for description. When the bearing seat 210 moves toward the through hole 1312 driven by the first control signal, the pin 220 is driven to move toward the through hole 1312, and gradually extends out of the through hole 1312.

[0042] When the pin 220 is in the second state exposed in the housing assembly 100, when the button 900 receives the user's operation again, it triggers the generation of a second control signal, and the second control signal is used to drive the bearing seat 210 to move, and the bearing seat 210 moves and drives the pin 220 to be received in the receiving space 1111 through the through hole 1312. In this embodiment, the second control signal drives the bearing seat 210 to move in a direction away from the through hole 1312 as an example for description. When the bearing seat 210 moves in a direction away from the through hole 1312 driven by the second control signal, it drives the pin 220 to pass through the through hole 1312 and gradually be received in the receiving space 1111.

[0043] Please also read Figure 5 , Figure 5A circuit block diagram of a power adapter provided for another embodiment of the present application. In another embodiment, the power adapter 10 further includes a communication module 800, such as a Bluetooth module, a Wireless Fidelity (WiFi) module, etc. The communication module 800 receives the control signal sent by other devices (such as a control device 60 such as a mobile phone), and drives the pin assembly 200 to move under the control of the control signal. When the power adapter 10 includes the communication module 800, the power adapter 10 may not include the button 900. Of course, when the power adapter 10 includes the communication module 800, the power adapter 10 may also include the button 900, so that the power adapter 10 can receive the control signal triggered by the button 900 and the control signal received by the communication module 800, so that the power adapter 10 can have two control modes to control the movement of the pin 220.

[0044] In the following embodiments, the power adapter 10 including the button 900 is taken as an example for illustration.

[0045] It should be noted that, in one embodiment, the first state of the power adapter 10 is the state in which the plug 220 is completely received in the receiving space 1111. In other words, all parts of the plug 220 are located in the receiving space 1111. When the plug 220 is retracted into the receiving space 1111 driven by the support base 210, the end of the plug 220 adjacent to the support base 210 is first retracted into the receiving space 1111, and then the end of the plug 220 away from the support base 210 is finally received in the receiving space 1111. When the end of the plug 220 away from the support base 210 is received in the receiving space 1111, the power adapter 10 can be regarded as being in the first state. In one embodiment, when the power adapter 10 is in the first state, the receiving of the plug 220 in the receiving space 1111 is blocked by the housing assembly 100, and it can no longer move toward the inside of the receiving space 1111. In another embodiment, the first state of the power adapter 10 is that the plug pin 220 is received in the receiving space 1111 and is shielded by the housing assembly 100 , and the plug pin 220 can continue to move toward the inside of the receiving space 1111 .

[0046] The second state of the power adapter 10 is a state in which the pin 220 is exposed to the housing assembly 100 through the through hole 1312 and can be used normally. In other words, when the power adapter 10 is in the second state, the pin 220 extends out of the through hole 1312 and can be inserted into the socket 50 to receive power.

[0047] Compared with the related art, the power adapter 10 provided in the embodiment of the present application has a second state in which the pin 220 is exposed in the housing assembly 100 through the through hole 1312, so the power adapter 10 can be used normally; in addition, the power adapter 10 also has a first state in which the pin 220 is accommodated in the accommodation space 1111, so when the power adapter 10 is not needed, the pin 220 can be retracted into the accommodation space 1111 to avoid damage to the pin 220, such as avoiding impact deformation, avoiding bending and causing functional failure, etc., so that the power adapter 10 has a longer service life. In addition, since the pin 220 is accommodated in the accommodation space 1111, it can also avoid damage to other items by the pin 220, and can avoid stabbing the user when the user carries it. Furthermore, the driving component 300 of the power adapter 10 provided in the embodiment of the present application can drive the pin component 200 to move under the control of the control electrical signal, thereby realizing the automatic extension and retraction of the pin component 200, which is more convenient to operate and has a strong sense of technology.

[0048] Please also read Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 , Figure 6 for Figure 3 A partial structural diagram of the power adapter; Figure 7 In one embodiment Figure 3 A cross-sectional view of a portion of the structure along line AA; Figure 8 for Figure 2 A schematic diagram of the structure of the driving component of the power adapter shown in; Fig. 9 for Figure 2 , a schematic structural diagram of the pin assembly at a certain viewing angle. The driving assembly 300 includes a driving member 310 and a rotating member 320. The driving member 310 is used to receive the control electrical signal and rotate under the control of the control electrical signal. The rotating member 320 is connected to the driving member 310 and is used to rotate under the rotation of the driving member 310. The bearing seat 210 has a threaded hole 2111. The rotating member 320 is inserted into the threaded hole 2111. When the rotating member 320 rotates in a preset direction, the bearing seat 210 is driven to move in a direction toward the through hole 1312. When the rotating member 320 rotates in a direction opposite to the preset direction, the bearing seat 210 is driven to move in a direction away from the through hole 1312.

[0049] The driving member 310 may be, but is not limited to, a stepper motor, the stepper motor having an output shaft, and when the stepper motor receives the control electrical signal, the output shaft is controlled to rotate under the control of the control electrical signal. The driving member 310 may be electrically connected to the circuit board 400 through a flexible printed circuit 400 (FPC) and a connector 420 to receive the control electrical signal. The connector may be, but is not limited to, a board to board connector (BTB). In one embodiment, the driving member 310 may be a stepper motor with a self-locking function, so that the pin 220 can maintain a relatively stable state without being moved. For example, when the power adapter 10 is in the second state in which the pin 220 is exposed in the through hole 1312, when the pin 220 is subjected to an external force, for example, when the pin 220 is inserted into the socket 50, it remains stable and does not move. Therefore, when the driving member 310 is a stepper motor with a self-locking function, the pin 220 can be prevented from retreating during use.

[0050] The rotating member 320 may be, but is not limited to, a screw rod. The rotating member 320 and the driving member 310 may be connected via a coupling, and the rotating member 320 may rotate under the drive of the driving member 310. In this embodiment, the driving member 310 drives the rotating member 320 to rotate axially, specifically, to rotate along a preset direction and in a direction opposite to the preset direction. For example, the preset direction is clockwise, and correspondingly, the direction opposite to the preset direction is counterclockwise; or, the preset direction is counterclockwise, and correspondingly, the direction opposite to the preset direction is clockwise.

[0051] In this embodiment, the bearing seat 210 includes a bearing portion 211 and a matching portion 213. The bearing portion 211 is used to bear the pin 220, and the matching portion 213 is provided with the threaded hole 211. The matching portion 213 and the bearing portion 211 may be fixed together by, but not limited to, hot melt. In another embodiment, the bearing seat 210 is an integral structure, in other words, the bearing portion 211 and the matching portion 213 are integral, and the bearing seat 210 has the threaded hole 211. The bearing seat 210 moves toward or away from the through hole 1312 driven by the rotating member 320 through the threaded matching between the threaded hole 2111 and the rotating member 320. In this embodiment, the rotating member 320 is a screw having a thread on the surface, and the screw matches the threaded hole 2111 of the bearing seat 210.

[0052] In this embodiment, the bearing seat 210 includes a first bearing surface 210a, a second bearing surface 210b and a connecting surface 210c. The first bearing surface 210a is a surface on which the pin 220 is exposed, and the first bearing surface 210a and the second bearing surface 210b are arranged opposite to each other. The connecting surface 210c connects the first bearing surface 210a and the second bearing surface 210b. The threaded hole 2111 passes through the first bearing surface 210a and the second bearing surface 210b. In this embodiment, the threaded hole 2111 passes through the central axis of the bearing seat 210 to ensure the stability of the bearing seat 210 when the rotating member 320 drives the bearing seat 210 to move.

[0053] Please continue reading Figures 6 to 10 The bearing seat 210 has a guide hole 2112, and the guide hole 2112 is spaced apart from the threaded hole 2111. The driving assembly 300 further includes a guide member 330, and the guide member 330 is fixed to and spaced apart from the rotating member 320. The guide member 330 is inserted into the guide hole 2112 of the bearing seat 210 to guide the bearing seat 210 when it moves toward or away from the through hole 1312.

[0054] In this embodiment, the guide hole 2112 passes through the first bearing surface 210a and the second bearing surface 210b. The bearing seat 210 includes the guide hole 2112, and the driving assembly 300 includes a guide member 330, which further improves the stability of the bearing seat 210 when the rotating member 320 drives the bearing seat 210 to move.

[0055] Please continue reading Figure 8 and Fig. 9 The driving assembly 300 includes two guide members 330 , the bearing seat 210 has two guide holes 2112 , and the two guide members 330 are respectively disposed on opposite sides of the rotating member 320 .

[0056] In this embodiment, the driving assembly 300 includes two guide members 330, and the supporting seat 210 has two guide holes 2112. One guide member 330 is arranged in one guide hole 2112, and the other guide member 330 is arranged in the other guide hole 2112, thereby further improving the stability of the rotating member 320 when driving the supporting seat 210 to move.

[0057] In this embodiment, the rotating member 320 is located at the center of the line connecting the two guide members 330. When the rotating member 320 is located at the center of the line connecting the two guide members 330, the guiding force of the two guide members 330 on the socket 50 is relatively consistent, thereby further improving the stability of the rotating member 320 when driving the bearing seat 210 to move.

[0058] In this embodiment, the driving assembly 300 further includes a first limit member 340 and a second limit member 350. The first limit member 340 and the second limit member 350 are disposed opposite to each other and spaced apart. The first limit member 340 is closer to the driving member 310 than the second limit member 350. Both ends of the guide member 330 are fixed to the first limit member 340 and the second limit member 350, respectively. Specifically, the first limit member 340 is disposed at one end of the guide member 330 and one end of the rotating member 320; the second limit member 350 is disposed at the other end of the guide member 330 and the other end of the rotating member 320, and the bearing seat 210 can move between the first limit member 340 and the second limit member 350 under the drive of the rotating member 320.

[0059] In this embodiment, the second stopper 350 is fixedly connected to the guide member 330, that is, it is non-detachably connected. Specifically, during assembly, the second stopper 350, the guide member 330 and the rotating member 320 are separate, and the bearing seat 210 is sleeved on the guide member 330 and the rotating member 320, and then the second stopper 350 is fixed to the guide member 330. For example, the fixed connection between the second stopper 350 and the guide member 330 may be, but is not limited to, welding, gluing, etc.

Specifically, in the present embodiment, the driving assembly 300 further includes two detachable fixing members 360, and the second position-limiting member 350 has two through holes 351 and a positioning hole 352. The two through holes 351 are arranged at intervals, and the positioning hole 352 is located between the two through holes 351, one end of the guide member 330 is passed through the through hole 351 and is detachably matched with the detachable fixing member 360, and one end of the rotating member 320 is arranged in the positioning hole 352. In the present embodiment, the positioning hole 352 is a blind hole.

[0061] In this embodiment, the detachable fixing member 360 is a member with internal threads, and one end of the guide member 330 has external threads. The guide member 330 and the detachable fixing member 360 are fixed by threaded fitting and are detachable.

[0062] In other embodiments, the detachable fixing member 360 may include a plug, and the guide member 330 may include a socket, and the plug is inserted into the socket to enable the detachable fixing member 360 to be detachably connected to the guide member 330 .

[0063] When the second position-limiting member 350 and the guide member 330 are detachably connected, during assembly, the bearing seat 210 is sleeved behind the guide member 330 and the rotating member 320 , and then the second position-limiting member 350 and the guide member 330 are fixed.

In this embodiment, the housing assembly 100 includes a first housing 110 , a second housing 120 , and a third housing 130 that are fixedly connected in sequence, so that the housing assembly 100 is easy to assemble.

[0066] Please continue reading Figures 4 to 10 , and see also Fig.12 and Fig.13 , Fig.12 for Figure 4 A schematic diagram of the first conductive member and the second housing being assembled together; Fig.13 for Fig.12The power adapter 10 further includes a circuit board 400 and a first conductive member 500. The circuit board 400 is accommodated in the first housing 110, and the first conductive member 500 is disposed on the second housing 120, and one end of the first conductive member 500 is electrically connected to the circuit board 400. The pin assembly 200 further includes a second conductive member 230, which is supported by the support seat 210 and electrically connected to the pin 220. When the pin 220 is fully exposed in the through hole 1312, the second conductive member 230 is electrically connected to the first conductive member 500.

[0067] The first conductive member 500 may be, but is not limited to, a conductive metal sheet. A portion of the first conductive member 500 passes through the second housing 120 and is fixed and electrically connected to the circuit board 400; another portion of the first conductive member 500 is disposed on the inner wall of the second housing 120. The method in which a portion of the first conductive member 500 is fixed and electrically connected to the circuit board 400 may be, but is not limited to, welding, bonding with conductive adhesive, etc. The number of the first conductive members 500 is two. The two first conductive members 500 are disposed on the second housing 120 at intervals.

[0068] The second conductive member 230 is a conductive spring. When the second conductive member 230 is electrically connected to the first conductive member 500 , the second conductive member 230 is in a compressed state, which can further ensure the electrical connection performance between the second conductive member 230 and the first conductive member 500 .

[0069] When the pin 220 is completely exposed in the through hole 1312, the second conductive member 230 is electrically connected to the first conductive member 500, so the pin 220 is electrically connected to the circuit board 400 through the second conductive member 230 and the first conductive member 500. The first voltage received by the pin 220 is transmitted to the circuit board 400 through the second conductive member 230 and the first conductive member 500, and the circuit board 400 converts the first voltage into a second voltage. For example, the first voltage is an AC voltage, and the second voltage is a DC voltage. The voltage value of the first voltage can be, but is not limited to, 220V, 110V, etc. The voltage value of the second voltage can be, but is not limited to, 5V, 24V, etc.

[0070] The first conductive member 500 includes a first conductive portion 510 and a second conductive portion 520. One end of the first conductive portion 510 is electrically connected to the circuit board 400. The second conductive portion 520 is connected to the first conductive portion 510, and the second conductive portion 520 is disposed adjacent to the through hole 1312 compared to the first conductive portion 510, and the width of the second conductive portion 520 is greater than the width of the first conductive portion 510.

[0071] Since the various components in the power adapter 10 have tolerances during assembly, in this embodiment, the width of the second conductive part 520 is greater than the width of the first conductive part 510. Therefore, when the pin 220 is fully extended out of the through hole 1312, the poor contact between the second conductive part 520 and the second conductive member 230 caused by factors such as the assembly tolerances of the various components in the power adapter 10 can be reduced or even avoided, and the electrical connection between the second conductive part 520 and the second conductive member 230 can be better guaranteed.

[0072] Please also read Figures 9 and 10 , and also see Fig.14 and Fig.15 , Fig.14 for Figure 4 A schematic structural diagram of the third housing at a viewing angle as shown in FIG. Fig.15 for Figure 4 The third housing 130 is a schematic diagram of another angle. The third housing 130 includes an end cover 131, a peripheral side plate 132 and a first limiting portion 133. The end cover 131 has the through hole 1312. The peripheral side plate 132 is disposed on the peripheral side of the end cover 131 and is connected to the end cover 131 by bending. The first limiting portion 133 is disposed on the inner wall of the peripheral side plate 132. The bearing seat 210 includes a bearing portion 211 and a second limiting portion 212. The bearing portion 211 is used to bear the pin 220. The second limiting portion 212 is disposed on the bearing portion 211. The second limiting portion 212 cooperates with the first limiting portion 133 to limit the bearing seat 210 relative to the movement direction of the third housing 130.

[0073] In this embodiment, the second limiting portion 212 cooperates with the first limiting portion 133 to limit the movement direction of the supporting base 210 relative to the third shell 130, thereby preventing the supporting base 210 from shaking greatly during the movement relative to the third shell 130, which may cause the pin 220 to fail to extend normally through the through hole 1312.

[0074] In this embodiment, the number of the first limiting parts 133 is two, and the two first limiting parts 133 are arranged on two opposite sides of the peripheral side wall. The number of the second limiting parts 212 is two, and the two second limiting parts 212 are arranged on two opposite sides of the bearing part 211. One second limiting part 212 cooperates with one first limiting part 133, and another second limiting part 212 cooperates with another first limiting part 133, so as to enhance the limiting effect when the bearing seat 210 moves relative to the third shell 130.

[0075] In this embodiment, the first limiting portion 133 is a convex strip protruding from the peripheral side plate 132 , and the second limiting portion 212 is a groove recessed in the bearing portion 211 .

[0076] The first limiting portion 133 is a convex strip protruding from the peripheral side plate 132 , so the structural strength of the third housing 130 can be improved.

[0077] Please also read Figure 4 , Fig.16 and Fig.17 , Fig.16 for Figure 4 A schematic diagram of a first housing in a power adapter shown in ; Fig.17 A circuit block diagram of a power adapter provided in one embodiment of the present application. The power adapter 10 further includes a circuit board 400, an output port 600, and a battery 700. The circuit board 400 is electrically connected to the pin 220, and is used to convert the first voltage received by the pin 220 into a second voltage. The output port 600 is electrically connected to the circuit board 400, and is used to output the second voltage. The battery 700 is electrically connected to the drive component 300, and is used to provide electrical energy to the drive component 300, and the battery 700 is also electrically connected to the circuit board 400, and is used to receive the second voltage and store electrical energy.

[0078] The first voltage and the second voltage are described above and will not be described again. In this embodiment, the output port 600 is a Universal Serial Bus (USB) interface, and the USB interface can be but is not limited to a USB 2.0 interface, a USB 3.0 interface, or a Type-C type interface.

[0079] In this embodiment, the circuit board 400 in the power adapter 10 converts the received first voltage into a second voltage, and outputs the second voltage to the electronic device 30 through the output port 600 to charge the electronic device 30. On the other hand, the second voltage is also used to charge the battery 700. Therefore, when the pin 220 of the power adapter 10 is inserted into the socket 50, so that the power adapter 10 charges the electronic device 30, it can also charge the battery 700 in the power adapter 10, thereby ensuring that the battery 700 has enough power to provide to the driving component 300.

[0080] It can be understood that initial electric energy is pre-stored in the battery 700. Therefore, when the power adapter 10 needs to be used, the battery 700 can provide initial electric energy to the driving component 300, so that the driving component 300 drives the pin component 200 to extend out of the through hole 1312.

[0081] In combination with the power adapter 10 provided in the above embodiments, the housing assembly 100 includes an end surface 1311 (see Figure 2 and Figure 3 ), the end surface 1311 constitutes the plug-in surface of the power adapter 10.

[0082] Please also read Fig.18 , Fig.18 is a schematic diagram of the distance from the edge of the pin to the edge of the end face. The so-called plug-in surface 11 of the power adapter 10 refers to the surface that cooperates with the socket 50 when the pin 220 of the power adapter 10 is inserted into the socket 50, and the plug-in surface 11 meets the safety requirements of the power adapter 10. When the pin 220 of the power adapter 10 is inserted into the socket 50, the surface that only cooperates with the socket 50 but does not meet the safety requirements of the power adapter 10 cannot be called the plug-in surface 11 of the power adapter 10. Specifically, for the power adapter 10, when the pin 220 of the power adapter 10 is inserted into the socket 50, in order to avoid the electrical energy of the socket 50 leaking out through the pin 220 and causing harm to the user, the distance d (such as Figure 3 ) needs to be greater than or equal to a preset distance (also called a safety distance). For example, for a power adapter 10 suitable for China, the preset distance is 6.5 mm. For a power adapter 10 suitable for other countries or regions (such as Europe), the preset distance is other values, such as 5.1 mm or 7.9 mm. In the schematic diagram of this embodiment.

[0083] Please also read Fig.19 , Fig.19This is a schematic diagram of an electronic device assembly provided in one embodiment of the present application. The electronic device assembly 1 includes an electronic device 30 and a power adapter 10 as described in any of the above embodiments, and the power adapter 10 is used to provide power to the electronic device 30 .

[0084] Generally, the power adapter 10 can convert AC voltage into DC voltage. For example, the power adapter 10 is plugged into the socket 50, receives the AC voltage output by the socket 50, and converts the received AC voltage into DC voltage, and the DC voltage is used to charge the battery 700 of the electronic device 30 such as a mobile phone and a computer. It can be understood that in other embodiments, the power adapter 10 converts the received AC voltage into DC voltage, and the DC voltage is directly used by the electronic components in the electronic device 30. Please refer to the previous description of the power adapter 10, which will not be repeated here.

[0085] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
