Referring to fig. 2, fig. 3 and fig. 4 together, fig. 2 is a schematic diagram of a power adapter according to an embodiment of the application in a first state;

Fig. 3 is a schematic view of the power adapter in fig. 2 in a second state, and fig. 4 is an exploded perspective view of the power adapter in fig. 2. The power adapter 10 includes a housing assembly 100, a pin assembly 200, and a drive 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 carrier 210 and pins 220, wherein the carrier 210 is accommodated in the accommodating space 1111, and the pins 220 are carried on the carrier 210 and can move along with the movement of the carrier 210. The driving assembly 300 is disposed in the accommodating space 1111, and is configured to control an electrical signal, and drive the pin assembly 200 to move under the control of the electrical signal, so that the power adapter 10 has a first state in which the pins 220 are accommodated in the accommodating space 1111 and a second state in which the pins 220 are exposed from the housing assembly 100 through the through holes 1312.

The housing assembly 100 has a receiving space 1111, the receiving space 1111 is configured to receive the pin assembly 200, and the housing assembly 100 may also be configured to receive and protect components in the power adapter 10, such as the circuit board 400, the battery 700, and the like. The shape of the housing assembly 100 may be, but is not limited to, cylindrical, oval cylindrical, cubic, square, etc. In the present embodiment, the outer shape of the housing assembly 100 is illustrated as a cylindrical-like shape, and it should be understood that the outer shape of the housing assembly 100 should not be construed as limiting the power adapter 10 provided by the present application. The extending direction of the housing assembly 100 is a preset extending direction. The through hole 1312 of 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 pins 220 protrude out of the receiving space 1111 through the through holes 1312. In the schematic diagram of the present embodiment, the number of the through holes 1312 is two. In other embodiments, the number of the through holes 1312 may be other numbers, such as three.

The material of the carrier 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 accommodating space 1111, so as to be able to move in the accommodating space 1111.

The pin 220 is made of metal, such as copper alloy, aluminum alloy, etc., and the pin 220 is plugged into the socket 50 for receiving the ac voltage provided by the socket 50. The number of pins 220 may be, but is not limited to, two, and in the schematic diagram of the present embodiment, the number of pins 220 is two, which are illustrated as an example, and two pins 220 are opposite and spaced apart. In other embodiments, the number of pins 220 is three. The pins 220 may be, but are not limited to, elongated. The end of the pin 220 facing away from the body of the socket 50 is curved to facilitate insertion of the pin 220 into the socket 50. The carrier 210 and the pins 220 may be secured together by, but not limited to, integral injection molding. The pins 220 are exposed at an end surface 1311 of the carrier 210 adjacent to the through holes 1312. In this embodiment, the movement direction of the pins 220 is the same as the movement direction of the carrier 210.

The driving assembly 300 is disposed in the accommodating space 1111, and is configured to receive a control signal and drive the pin assembly 200 to move under the control of the control 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 accepts a user operation and triggers the control signal. In the following, a detailed process of receiving the control signal by the user operation of the button 900 and driving the pin 220 to move will be described.

When the pins 220 are in the first state of being received in the receiving spaces 1111, the button 900 is triggered to generate a first control signal when receiving a user operation, where the first control signal is used to drive the carrier 210 to move, and the carrier 210 moves to drive the pins 220 to be exposed to the housing assembly 100 through the through holes 1312. In this embodiment, the first control signal drives the carrier 210 to move toward the direction of the through hole 1312 is taken as an example. When the carrier 210 is driven by the first control signal to move toward the through hole 1312, the pin 220 is driven to move toward the through hole 1312, and gradually extends out of the through hole 1312.

When the pins 220 are in the second state exposed to the housing assembly 100, the button 900 is triggered to generate a second control signal when receiving the user operation again, the second control signal is used to drive the carrier 210 to move, and the carrier 210 moves to drive the pins 220 to be received in the receiving space 1111 through the through holes 1312. In this embodiment, the second control signal drives the carrier 210 to move in a direction away from the through hole 1312 is taken as an example. When the carrier 210 is driven by the second control signal to move in a direction away from the through hole 1312, the pins 220 are driven to be gradually accommodated in the accommodating space 1111 through the through hole 1312.

Referring to fig. 5, fig. 5 is a circuit block diagram of a power adapter according to another embodiment of the application. In another embodiment, the power adapter 10 further includes a communication module 800, such as a Bluetooth module, a wireless fidelity (WIRELESS FIDELITY, WIFI) module, or the like. The communication module 800 receives the control signal sent by other devices (such as the control device 60 of the mobile phone, etc.), 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 further include a button 900, so that the power adapter 10 can receive a control signal triggered by the button 900 and a control signal received by the communication module 800, so that the power adapter 10 can control the movement of the pin 220 in two control manners.

In the following embodiment, the power adapter 10 is illustrated as including the button 900.

In one embodiment, the first state of the power adapter 10 is a state in which the pins 220 are completely received in the receiving spaces 1111, in other words, all the positions of the pins 220 are located in the receiving spaces 1111. When the pin 220 is retracted into the accommodating space 1111 under the driving of the carrier 210, an end of the pin 220 adjacent to the carrier 210 is retracted into the accommodating space 1111, and then an end of the pin 220 facing away from the carrier 210 is finally accommodated in the accommodating space 1111. When the end of the pin 220 facing away from the carrier 210 is received in the receiving space 1111, the power adapter 10 is in the first state. In one embodiment, when the power adapter 10 is in the first state, the pin 220 is accommodated in the accommodation space 1111 and is blocked by the housing assembly 100, and can not move toward the inside of the accommodation space 1111. In another embodiment, the first state of the power adapter 10 is that the pins 220 are accommodated in the accommodation spaces 1111 and blocked by the housing assembly 100, and the pins 220 can further move toward the inside of the accommodation spaces 1111.

The second state of the power adapter 10 is a state in which the pins 220 are exposed from the housing assembly 100 through the through holes 1312 and can be used normally. In other words, when the power adapter 10 is in the second state, the pins 220 protrude through the through holes 1312 and can be inserted into the socket 50 to receive power.

In comparison with the related art, the power adapter 10 according to the embodiment of the application has the second state that the pins 220 are exposed from the housing assembly 100 through the through holes 1312, so that the power adapter 10 can be used normally, and the power adapter 10 also has the first state that the pins 220 are accommodated in the accommodating space 1111, so that the pins 220 can be retracted in the accommodating space 1111 when the power adapter 10 is not needed, and damage to the pins 220, such as impact deformation, functional failure caused by bending, etc., can be avoided, so that the power adapter 10 has a longer service life. In addition, since the pins 220 are accommodated in the accommodation spaces 1111, damage to other objects by the pins 220 can be avoided, and a user carrying a time stamp can be avoided. Furthermore, the driving component 300 of the power adapter 10 according to the embodiment of the present application can drive the pin component 200 to move under the control of the control signal, so as to realize the automatic extension and retraction of the pin component 200, and the operation is more convenient and has a stronger feeling of science and technology.

The driving assembly 300 includes a driving member 310 and a rotating member 320, wherein the driving member 310 is configured to receive the control electrical signal and rotate under the control of the control electrical signal, and the rotating member 320 is connected to the driving member 310 and is configured to rotate under the driving of 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, and when the rotating member 320 rotates in a preset direction, the bearing seat 210 is driven to move along a direction toward the through hole 1312, and when the rotating member 320 rotates in a direction opposite to the preset direction, the bearing seat 210 is driven to move along a direction away from the through hole 1312.

The driving member 310 may be, but is not limited to, a stepper motor having an output shaft, and the output shaft is controlled to rotate under the control of the control electrical signal when the stepper motor receives the control electrical signal. The driving member 310 may be electrically connected to the circuit board 400 through a flexible circuit board 400 (Flexible Printed Circuit, FPC) and a connector 420 to receive the control electrical signal. The connector may be, but is not limited to, a Board-to-Board (BTB) connector. In one embodiment, the driving member 310 may be a stepping motor having a self-locking function, so that the pins 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 pins 220 are exposed to the through holes 1312, the pins 220 remain stable against movement when an external force is applied to the pins 220, such as when the pins 220 are inserted into the sockets 50. Therefore, when the driving member 310 is a stepper motor with self-locking function, the pin 220 is prevented from being retracted during use.

The rotating member 320 may be, but not limited to, a screw, and the rotating member 320 and the driving member 310 may be connected by a coupling, and the rotating member 320 may be driven by the driving member 310 to rotate. In this embodiment, the driving member 310 drives the rotating member 320 to rotate axially, specifically, in a preset direction and in a direction opposite to the preset direction. For example, the preset direction is clockwise, and correspondingly, the opposite direction of the preset direction is counterclockwise, or the preset direction is counterclockwise, and correspondingly, the opposite direction of the preset direction is clockwise.

The engaging portion 213 and the bearing portion 211 may be fixed together by, but not limited to, heat fusion. In another embodiment, the bearing seat 210 is of an integral structure, in other words, the bearing portion 211 and the mating portion 213 are integral, and the bearing seat 210 has the threaded hole 211 therein. The bearing seat 210 is in threaded engagement with the rotating member 320 through the threaded hole 2111, so as to move toward or away from the through hole 1312 under the driving of the rotating member 320.

The pin assembly 200 further has a second conductive member 230, wherein the second conductive member 230 is carried on the carrier 210 and is electrically connected to the pin 220, and when the pin 220 is completely exposed from the through hole 1312, the second conductive member 230 is electrically connected to the first conductive member 500.

The first conductive member 500 may be, but is not limited to, a conductive metal sheet. A part of the first conductive member 500 passes through the second housing 120 and is fixed and electrically connected to the circuit board 400, and another part of the first conductive member 500 is disposed on an inner wall of the second housing 120. The first conductive member 500 may be fixed to and electrically connected to the circuit board 400 by, but not limited to, soldering, bonding with conductive adhesive, or the like. 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.

The second conductive member 230 is a conductive elastic sheet, and when the second conductive member 230 is electrically connected with the first conductive member 500, the second conductive member 230 is in a compressed state, so as to further ensure the electrical connection performance between the second conductive member 230 and the first conductive member 500.

When the pins 220 are completely exposed from the through holes 1312, the second conductive members 230 are electrically connected to the first conductive members 500, and thus, the pins 220 are electrically connected to the circuit board 400 through the second conductive members 230 and the first conductive members 500. The first voltage received on the pin 220 is transferred 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 the 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 may be, but is not limited to, 220v,110v, etc. The voltage value of the second voltage may be, but is not limited to, 5v,24v, etc.

Since the respective components of the power adapter 10 have a tolerance in assembly, in this embodiment, the width of the second conductive portion 520 is greater than the width of the first conductive portion 510, when the pins 220 are completely extended out of the through holes 1312, contact failure between the second conductive portion 520 and the second conductive member 230 due to the assembly tolerance of the respective components of the power adapter 10 can be reduced or even avoided, and electrical connection between the second conductive portion 520 and the second conductive member 230 can be better ensured.

Referring to fig. 4, 16 and 17, fig. 16 is a schematic view of a first housing of the power adapter shown in fig. 4, and fig. 17 is a circuit block diagram of the power adapter according to an embodiment of the 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 pins 220, and is configured to convert a first voltage received by the pins 220 into a second voltage. The output port 600 is electrically connected to the circuit board 400, and is configured to output the second voltage. The battery 700 is electrically connected to the driving assembly 300 for supplying power to the driving assembly 300, and the battery 700 is also electrically connected to the circuit board 400 for receiving the second voltage and storing power.

The first voltage and the second voltage are described above, and are not described herein. In this embodiment, the output port 600 is a universal serial bus (Universal Serial Bus, USB) interface, which may be, but is not limited to, a USB 2.0 interface, a USB 3.0 interface, or a Type-C interface.

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, so as to charge the electronic device 30. In another aspect, the second voltage is also used to charge the battery 700. Therefore, when the pins 220 of the power adapter 10 are inserted into the sockets 50, so that the power adapter 10 charges the electronic device 30, the battery 700 in the power adapter 10 may also be charged, thereby ensuring that the battery 700 has enough power to supply to the driving assembly 300.

As can be appreciated, the battery 700 stores initial power in advance, so that when the power adapter 10 needs to be used, the battery 700 can supply initial power to the driving unit 300, so that the driving unit 300 drives the pin unit 200 to protrude out of the through hole 1312.

In connection with the power adapter 10 provided in the foregoing embodiments, the housing assembly 100 includes an end surface 1311 (see fig. 2 and 3) provided with the through hole 1312, and the end surface 1311 forms a mating surface of the power adapter 10.

Referring to fig. 18, fig. 18 is a schematic diagram illustrating the distance from the edge of the pin to the edge of the end face. The mating surface 11 of the power adapter 10 is a surface that mates with the socket 50 when the pins 220 of the power adapter 10 are inserted into the socket 50, and the mating surface 11 meets the requirements of safety regulations of the power adapter 10. When the pins 220 of the power adapter 10 are inserted into the sockets 50, a surface that merely mates with the sockets 50 but does not meet the safety regulations of the power adapter 10 cannot be referred to as a mating surface 11 of the power adapter 10. Specifically, for the power adapter 10, when the pins 220 of the power adapter 10 are inserted into the sockets 50, a distance d (see fig. 3) from the edge of the pins 220 to the edge of the end surface 1311 needs to be greater than or equal to a predetermined distance (also referred to as a safety distance) in order to avoid injury to a user caused by leakage of power from the sockets 50 through the pins 220. For example, for a power adapter 10 suitable for use in China, the predetermined distance is 6.5mm. For power adapters 10 that are suitable for use in other countries or regions (e.g., europe), the preset distance is another value, such as 5.1mm, or 7.9mm. In the schematic diagram of this embodiment.

Referring to fig. 19 together, fig. 19 is a schematic diagram of an electronic device assembly according to an embodiment of the application. The electronic device assembly 1 comprises an electronic device 30 and the power adapter 10 according to any of the previous embodiments, wherein the power adapter 10 is configured to provide power supply to the electronic device 30.

Typically, the power adapter 10 may convert an ac voltage to a dc voltage. For example, the power adapter 10 is plugged into the socket 50, receives an ac voltage output from the socket 50, and converts the received ac voltage into a dc voltage, which is used to charge the battery 700 of the electronic device 30 for power consumption such as a mobile phone or a computer. It will be appreciated that in other embodiments, the power adapter 10 converts the received ac voltage to a dc voltage that is directly used by the electronic components in the electronic device 30. The power adapter 10 is described above, and will not be described in detail herein.
