The present application provides a Power adapter 10. Referring to fig. 1, fig. 1 is a schematic application environment diagram of a power adapter according to an embodiment of the present disclosure. The power adapter 10 is a conversion device that supplies power to the electronic device 30. Generally, the power adapter 10 may convert an alternating voltage to a direct 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 a dc voltage, which is used to charge the electronic device 30 using electricity, such as a mobile phone and a computer. It is to be appreciated that in other embodiments, the power adapter 10 converts the received ac voltage to a dc voltage that is directly available to the electronic components in the electronic device 30. It is to be understood that the schematic diagram of the application environment of the power adapter 10 is only helpful for understanding the application of the power adapter 10, and should not be construed as limiting the power adapter 10 provided in the present application.

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

FIG. 3 is a schematic diagram of the power adapter of FIG. 2 in a second state; fig. 4 is an exploded perspective view of the power adapter of 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, the carrier 210 is received in the receiving 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 receiving space 1111 and configured 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 pins 220 are received in the receiving space 1111 and a second state in which the pins 220 are exposed to the housing assembly 100 through the through holes 1312.

The housing assembly 100 has a receiving space 1111 for receiving the pin assembly 200, and the housing assembly 100 can also be used for receiving and protecting 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, elliptic cylindrical, cubic, or the like. In the present embodiment, the external shape of the housing assembly 100 is illustrated as a cylinder-like shape, and it should be understood that the external shape of the housing assembly 100 should not be construed as limiting the power adapter 10 provided in the present application. The extending direction of the housing assembly 100 is a preset extending direction. The through holes 1312 on the housing assembly 100 are used for the pins 220 to extend out of or retract into the receiving spaces 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 the present embodiment, the number of the through holes 1312 is two for illustration. In other embodiments, the number of the through holes 1312 may be other numbers, such as three.

The material of the carrying base 210 is an insulating material, such as plastic, rubber, plastic, ceramic, etc. The shape of the carrying seat 210 is adapted to the shape of the receiving space 1111 to be capable of moving in the receiving space 1111.

The plug 220 is made of metal, such as copper alloy, aluminum alloy, etc., and the plug 220 is inserted into the socket 50 for receiving an ac voltage provided by the socket 50. The number of the pins 220 may be, but not limited to, two, and in the schematic diagram of the present embodiment, the number of the pins 220 is taken as two for illustration, and the two pins 220 are arranged oppositely and at an interval. In other embodiments, the number of the pins 220 is three. The pins 220 may be, but are not limited to, elongated shapes. 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 bearing seat 210 and the pins 220 can be fixed together by, but not limited to, integral injection molding. The pins 220 are exposed at an end surface 1311 of the carrier 210 near the through holes 1312. In this embodiment, the moving direction of the pins 220 is the same as the moving direction of the carrier 210.

The driving assembly 300 is disposed in the receiving space 1111 and configured 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 provided on the housing assembly 100. The button 900 accepts user operation and triggers the control signal. In one embodiment, the detailed process of the button 900 receiving the user operation to trigger the control signal and the control signal driving the pins 220 to move is described below.

When the plug pins 220 are in the first state of being accommodated in the accommodating space 1111 and when the button 900 receives the operation of the user, a first control signal is generated by triggering, the first control signal is used for driving the carrying seat 210 to move, and the carrying seat 210 moves to drive the plug 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 through hole 1312. When the bearing seat 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 then gradually extends out of the through hole 1312.

When the plug pins 220 are in the second state exposed to the housing assembly 100, when the button 900 receives the operation of the user again, a second control signal is generated by triggering, the second control signal is used for driving the carrying seat 210 to move, and the carrying seat 210 moves to drive the plug pins 220 to be accommodated in the accommodating space 1111 through the through holes 1312. In this embodiment, a description will be given by taking the second control signal to drive the bearing seat 210 to move away from the through hole 1312. When the bearing seat 210 moves in a direction away from the through hole 1312 under the driving of the second control signal, the pins 220 are further 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 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, and the like. The communication module 800 receives the control signal sent by another device (such as the control device 60 like 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 further include a 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, and thus the power adapter 10 can have two control modes to control the movement of the pins 220.

In the following embodiments, the power adapter 10 includes the button 900 as an example for illustration.

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

The second state of the power adapter 10 is a state in which the pins 220 are exposed to 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 from the through holes 1312 and can be inserted into the sockets 50 to receive power.

Compared with the related art, the power adapter 10 provided in the embodiment of the present application has the second state in which the pins 220 are exposed to the housing assembly 100 through the through holes 1312, so that the power adapter 10 can be normally used; in addition, the power adapter 10 further has a first state that the pins 220 are accommodated in the accommodating space 1111, so that when the power adapter 10 is not needed to be used, the pins 220 can be retracted into the accommodating space 1111, thereby preventing the pins 220 from being damaged, for example, preventing impact deformation and functional failure caused by bending, and further allowing the power adapter 10 to have a longer service life. In addition, since the pins 220 are accommodated in the accommodating space 1111, damage to other articles by the pins 220 can be avoided, and a user can be prevented from having a time stamp. Furthermore, the driving assembly 300 of the power adapter 10 provided in the embodiment of the present application can drive the pin assembly 200 to move under the control of the control electrical signal, so as to realize the automatic extension and retraction of the pin assembly 200, and the operation is convenient and fast, and has a strong technological sense.

Please refer to fig. 6, fig. 7, fig. 8, fig. 9, and fig. 10, in which fig. 6 is a schematic partial structure diagram of the power adapter in fig. 3; FIG. 7 isbase:Sub>A cross-sectional view ofbase:Sub>A portion of the structure of FIG. 3 taken along line A-A, in accordance with one embodiment; FIG. 8 is a schematic structural diagram of a drive assembly of the power adapter shown in FIG. 2; figure 9 is a schematic diagram of the pin assembly shown in figure 2 from a perspective view. The driving assembly 300 includes a driving member 310 and a rotating member 320, 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 configured to rotate under the rotation of the driving member 310. The carrying seat 210 has a threaded hole 2111, the rotating member 320 is disposed through the threaded hole 2111, and when the rotating member 320 rotates in a predetermined direction, the carrying 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 predetermined direction, the carrying base 210 is driven to move in a direction away from the through hole 1312.

The driving member 310 may be, but not limited to, a stepping motor having an output shaft, and when the stepping motor receives the control electrical signal, the output shaft is controlled to rotate under the control of the control electrical signal. The driver 310 may be electrically connected to the Circuit board 400 through a Flexible Printed Circuit (FPC) 400 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 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 pins 220 are exposed from the through holes 1312, the pins 220 are stable and do not move when subjected to an external force, such as when the pins 220 are inserted into the sockets 50. Therefore, when the driving member 310 is a stepping motor with a self-locking function, the pin 220 is prevented from backing during use.

The rotating member 320 may be, but not limited to, a screw, the rotating member 320 and the driving member 310 may be connected by a coupling, and the rotating member 320 may be rotated by the driving member 310. In the present embodiment, the driving member 310 drives the rotating member 320 to rotate axially, specifically, to rotate along a predetermined direction and to rotate in a direction opposite to the predetermined direction. For example, the preset direction is a clockwise direction, and correspondingly, the direction opposite to the preset direction is an anticlockwise direction; or, the preset direction is a counterclockwise direction, and correspondingly, the direction opposite to the preset direction is a clockwise direction.

The bearing part 211 is used for bearing the pins 220, and the matching part 213 is provided with the threaded hole 211. The fitting portion 213 and the bearing portion 211 may be, but not limited to, fixed together by heat fusion. In another embodiment, the bearing seat 210 is a unitary structure, in other words, the bearing portion 211 and the mating portion 213 are unitary, and the bearing seat 210 has the threaded hole 211 therein.

The 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, 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 has a second conductive member 230, the second conductive member 230 is carried on the carrying seat 210 and electrically connected to the pin 220, and when the pin 220 is completely exposed to 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 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 an inner wall of the second housing 120. The way of fixing and electrically connecting a portion of the first conductive member 500 to the circuit board 400 may be, but is not limited to, welding, bonding with a conductive adhesive, and 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 to the first conductive member 500, the second conductive member 230 is in a compressed state, so that the electrical connection performance between the second conductive member 230 and the first conductive member 500 can be further ensured.

When the pin 220 is completely exposed to the through hole 1312, the second conductive member 230 is electrically connected to the first conductive member 500, and thus 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 on 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, and the like. The voltage value of the second voltage may be, but is not limited to, 5v,24v, and the like.

The first conductive member 500 includes a first conductive portion 510 and a second conductive portion 520. One end of the first conductive part 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 a width of the second conductive portion 520 is greater than a width of the first conductive portion 510.

Since each component of the power adapter 10 has tolerance during assembly, in the present embodiment, the width of the second conductive part 520 is greater than the width of the first conductive part 510, so that when the pins 220 completely protrude out of the through holes 1312, poor contact between the second conductive part 520 and the second conductive part 230 due to factors such as assembly tolerance of each component of the power adapter 10 can be reduced or even avoided, and electrical connection between the second conductive part 520 and the second conductive part 230 can be better ensured.

Referring to fig. 9 to 10 together with fig. 14 and 15 together, fig. 14 is a schematic structural view of the third housing shown in fig. 4 at a viewing angle; fig. 15 is a schematic view of the third housing shown in fig. 4 at another angle. The third casing 130 includes an end cover 131, a peripheral side plate 132 and a first stopper 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 in a bent manner, and the first stopper 133 is disposed on the inner wall of the peripheral side plate 132. The carrying seat 210 includes a carrying portion 211 and a second position-limiting portion 212, the carrying portion 211 is used for carrying the pins 220, the second position-limiting portion 212 is disposed on the carrying portion 211, and the second position-limiting portion 212 and the first position-limiting portion 133 cooperate to limit the movement direction of the carrying seat 210 relative to the third housing 130.

In this embodiment, the second position-limiting portion 212 and the first position-limiting portion 133 cooperate to limit the movement direction of the bearing seat 210 relative to the third housing 130, so as to prevent the pin 220 from being unable to normally extend through the through hole 1312 due to large shaking generated during the movement of the bearing seat 210 relative to the third housing 130.

In this embodiment, the number of the first stoppers 133 is two, and two first stoppers 133 are disposed on opposite sides of the peripheral wall. The number of the second position-limiting portions 212 is two, and the two second position-limiting portions 212 are disposed on two opposite sides of the carrying portion 211. One second position-limiting portion 212 is engaged with one first position-limiting portion 133, and the other second position-limiting portion 212 is engaged with the other first position-limiting portion 133, so as to improve the position-limiting effect when the carrying base 210 moves relative to the third housing 130.

In this embodiment, the first position-limiting portion 133 is a convex strip protruding from the peripheral side plate 132, and the second position-limiting portion 212 is a concave groove recessed in the carrying portion 211.

The first position-limiting portions 133 are protruding strips protruding from the peripheral side plate 132, so that the structural strength of the third housing 130 can be improved.

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; fig. 17 is a circuit block diagram of a power adapter according to an 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 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 providing electric energy to the driving assembly 300, and the battery 700 is further electrically connected to the circuit board 400 for receiving the second voltage and storing the electric energy.

The first voltage and the second voltage refer to the foregoing description, and are not repeated herein. In this embodiment, the output port 600 is a Universal Serial Bus (USB) interface, and the USB interface may be, but is not limited to, a USB 2.0 interface, a USB 3.0 interface, or a Type-C interface.

In the present 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 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 can also be charged, thereby ensuring that the battery 700 has enough power to supply to the driving assembly 300.

It will be appreciated that the battery 700 has initial power stored therein, and therefore, when the power adapter 10 is required to be used, the battery 700 can provide the initial power to the driving assembly 300, so that the driving assembly 300 drives the pin assembly 200 to extend out of the through hole 1312.

In conjunction 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 plugging surface of the power adapter 10.

Referring to fig. 18, fig. 18 is a schematic view illustrating the distance from the edge of the pin to the edge of the end face. The plugging surface 11 of the power adapter 10 is a surface which is engaged with the socket 50 when the pins 220 of the power adapter 10 are inserted into the socket 50, and the plugging surface 11 satisfies the safety requirements of the power adapter 10. When the pins 220 of the power adapter 10 are inserted into the sockets 50, only the surface that is mated with the sockets 50 but does not meet the safety regulations of the power adapter 10 cannot be referred to as the plugging 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, in order to prevent the power of the sockets 50 from leaking out through the pins 220 to cause injury to users, a distance d (as shown in fig. 3) between the edges of the pins 220 and the edge of the end surface 1311 needs to be greater than or equal to a preset distance (also referred to as a safety distance). For example, for the power adapter 10 suitable for china, the predetermined distance is 6.5mm. For power adapters 10 suitable for use in other countries or regions, such as europe, the predetermined distance may be other values, such as 5.1mm, or 7.9mm. In the schematic diagram of the present embodiment.

Referring to fig. 19, fig. 19 is a schematic view of an electronic device assembly according to an embodiment of the present disclosure. The electronic device assembly 1 includes an electronic device 30 and the power adapter 10 according to any of the foregoing embodiments, where the power adapter 10 is configured to provide power for the electronic device 30.

Generally, the power adapter 10 can convert an alternating current voltage into a direct current voltage. For example, the power adapter 10 is plugged into the socket 50, receives the 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 that uses electricity, such as a mobile phone and a computer. It is understood that in other embodiments, the power adapter 10 converts the received ac voltage to a dc voltage, and the dc voltage is directly supplied to the electronic components in the electronic device 30. Please refer to the foregoing description for the power adapter 10, which is not repeated herein.
