The housing assembly 110 has a receiving space 1111 for receiving the pin assembly 130, and the housing assembly 110 can also be used for receiving and protecting components in the power adapter 10, such as the circuit board 400. The shape of the housing assembly 110 may be, but is not limited to, cylindrical, elliptic cylindrical, cubic, square, etc. In the present embodiment, the outer shape of the housing assembly 110 is illustrated as a cylinder-like shape, and it should be understood that the outer shape of the housing assembly 110 should not be construed as limiting the power adapter 10 provided in the present application. The extending direction of the housing assembly 110 is a preset extending direction. The through holes 112a of the housing assembly 110 are used for the pins 132 to extend out of or retract into the receiving space 1111. The number of the through holes 112a and the number of the pins 132 are adapted to allow all the pins 132 to extend out of the receiving space 1111 through the through holes 112 a.

In this embodiment, the pins 132 are fixed on the carrier 131, and the moving direction of the pins 132 is the same as the moving direction of the carrier 131. In other embodiments, the moving direction of the pins 132 is different from the moving direction of the carrying seat 131, for example, the moving direction of the pins 132 forms an included angle with the moving direction of the carrying seat 131, as long as the pins 132 can be exposed to the housing assembly 110 through the through holes 112a under the driving of the carrying seat 131, and can be accommodated in the housing assembly 110 under the driving of the carrying seat 131.

The carrying seat 131 is accommodated in the accommodating space 1111, and the pins 132 are carried on the carrying seat 131 and can extend and retract along the direction of the through hole 12a of the housing assembly 110 along with the movement of the carrying seat 131. The pins 132 are carried on the carrying seat 131 and can extend and retract along the direction of the through holes 112a of the housing assembly 110 with the movement of the carrying seat 131.

In one embodiment, the carriage 131 can be driven by a driving mechanism. When the bearing seat 131 is electrically driven by the driving mechanism, the first shell 111 and the second shell 112 of the shell assembly 110 can be fixedly connected. In the present embodiment, the example that the carrying seat 131 is manually driven to move is illustrated, and a moving process of the carrying seat 131 will be described later, it should be understood that the moving manner of the carrying seat 131 should not be construed as a limitation to the power adapter 10 provided in the embodiments.

The material of the bearing seat 131 is an insulating material, such as plastic, rubber, plastic, ceramic, etc. The shape of the carrying seat 131 is adapted to the shape of the receiving space 1111 to be capable of moving in the receiving space 1111.

The plug 132 is made of metal, such as copper alloy, aluminum alloy, etc., and the plug 132 is inserted into the socket 50 for receiving an ac voltage provided by the socket 50. The number of the pins 132 may be, but not limited to, two, and in the schematic diagram of the embodiment, the number of the pins 132 is illustrated as two, and the two pins 132 are opposite and spaced apart from each other. In other embodiments, the number of pins 132 is three. The pins 132 may be, but are not limited to, elongated. The end of the pin 132 facing away from the body of the socket 50 is curved to facilitate insertion of the pin 132 into the socket 50. The carrier 131 and the pins 132 may be integrally formed by, but not limited to, insert molding. The pins 132 are exposed at the end surface 112b of the carrier 131 close to the through holes 112 a. In this embodiment, the moving direction of the pins 132 is the same as the moving direction of the carrier 131.

In the present embodiment, the receiving state of the power adapter 10 refers to a state in which the pins 132 are at least partially received in the receiving space 1111. The pins 132 are at least partially accommodated in the accommodating space 1111, including the pins 132 being partially accommodated in the accommodating space 1111 and the pins 132 being completely accommodated in the accommodating space 1111. When the pin 132 is partially received in the receiving space 1111, a part of the pin 132 is received in the receiving space 1111, and another part of the pin 132 is exposed to the housing assembly 110; when the pin 132 is completely received in the receiving space 1111, all portions of the pin 132 are located in the receiving space 1111. The working state of the power adapter 10 refers to a state that the pins 132 are exposed to the housing assembly 110 through the through holes 112a and can be used normally. When the pins 132 of the power adapter 10 are exposed to the housing assembly 110 only through the pins 132, the status that the pins 132 are exposed to the housing assembly 110 is not the working status of the power adapter 10 because the size of the pins 132 is small. It is understood that the operating state of the power adapter 10 means that the pins 132 are exposed from the housing assembly 110 and can be used normally, and do not represent the power adapter 10 being inserted into the socket 50 and used during the operation, and whether the power adapter 10 is inserted into the socket 50 or not.

In this embodiment, when the power adapter 10 is in a state that the pins 132 are completely accommodated in the accommodating space 111, when the bearing seat 131 is acted by a force and moves toward the through holes 112a, one ends of the pins 132 facing away from the bearing seat 131 are exposed to the housing assembly 110 through the through holes 112a, the rest portions of the pins 132 are gradually exposed to the housing assembly 110 through the through holes 112a, and when the pins 132 extend to a limit degree and cannot extend further, the power adapter 10 is in a working state.

When the power adapter 10 is in an operating state, when the carrying seat 131 is acted by a force to move away from the through hole 112a, one end of the pin 132 adjacent to the carrying seat 131 is firstly accommodated in the accommodating space 1111 through the through hole 112a, the rest of the pin 132 is gradually accommodated in the accommodating space 1111 through the through hole 112a, and when the pin 132 is accommodated in the accommodating space 1111 and cannot further enter the accommodating space 1111, the power adapter 10 is in an accommodating state.

The electrical connection assembly 140 is used to electrically connect the pins 132 and the circuit board assembly 120 when the power adapter 10 is in an operating state. It is understood that the pins 132 are disconnected from the electrical connection assembly 140 when the power adapter 10 is in a state other than the operating state (e.g., in the receiving state). In another embodiment, the pins 132 are electrically connected to the electrical connection assembly 140 when the power adapter 10 is in a state other than the operating state. The electrical connection relationship between the pins 132 and the electrical connection assembly 140 when the power adapter 10 is in other states than the operating state should not be understood as limiting the connection relationship between the pins 132 and the electrical connection assembly 140 when the power adapter 10 is in the operating state. In this embodiment, the plug 132 is disconnected from the electrical connection component 140 when the power adapter 10 is in a state other than the operating state.

Compared with the related art, the pin 132 of the power adapter 10 and the electrical connection element 140 form two conductive paths to be electrically connected to the circuit board element 120, so that the pin 132 and the electrical connection element 140 are electrically connected with each other more reliably, the unreliable or ineffective electrical conduction between the pin element 130 and the circuit board element 120 caused by the poor or unstable contact between the pin 132 and the electrical connection element 140 is prevented, and meanwhile, the sparking phenomena such as electric arcs or electric sparks at the contact position between the pin 132 and the electrical connection element 140 are avoided. Further avoiding the adverse effects of the temperature rise of the local position caused by the generation of electric arcs or electric sparks, the further melting of the shell assembly 110 and the like.

When the first housing 111 rotates relative to the second housing 112, the driving member 162 rotates relative to the second housing 112, and the driving member 162 is driven to drive the carrying seat 131 to move.

The bearing seat 131 includes a guide groove (i.e., a fourth engaging portion 1313), the second housing 112 includes an end cover 1121, a peripheral side plate 1122, and a guide rail (i.e., a fifth engaging portion 1123), the end cover 1121 has the through hole 112a, the peripheral side plate 1122 is disposed on the peripheral side of the end cover 1121 and is connected to the end cover 1121 in a bending manner, the guide rail is disposed on the inner wall of the peripheral side plate 1122, the guide rail is engaged with the guide groove to limit the movement direction of the bearing seat 131 relative to the second housing 112, the first magnetic member 171 is disposed in the guide groove, and the second magnetic member 172 is disposed in the guide rail.

In the present embodiment, the first magnetic member 171 and the second magnetic member 172 are disposed by using the guide groove and the guide rail that limit the movement of the holder 131 relative to the second housing 112, so that the space between the holder 131 and the second housing 112 can be fully utilized, which is advantageous for the miniaturization of the power adapter 10.

When the carrying seat 131 carries the pins 132 to pass through the through holes 112a to the position near the fully extended position, the first magnetic member 171 is repelled by the magnetic force of the second magnetic member 172, so as to rapidly carry the carrying seat 131 to continue moving toward the through holes 112a, so that the pins 132 are fully extended, and the power adapter 10 is in the working state. As can be seen from the above description, when the plug 132 is located at a position near the full extension position to the full extension position, the magnetic repulsion between the first magnetic member 171 and the second magnetic member 172 of the carrying seat 131 can rapidly drive the carrying seat 131 to move toward the through hole 112a, so that the user can feel different hand feeling from others, and the plug 132 can be prompted to fully extend.

Accordingly, when the carrying seat 131 drives the pins 132 to retract into the receiving space 1111 through the through holes 112a, the first magnetic member 171 is repelled by the magnetic force between the second magnetic members 172, so as to rapidly drive the carrying seat 131 to move in a direction away from the through holes 112a, so that the pins 132 are completely retracted, and the power adapter 10 is in the receiving state. It can be seen that when the power adapter 10 is in the vicinity of the storage state, the user can feel a different hand feeling from the other part due to the magnetic repulsion between the first magnetic member 171 and the second magnetic member 172, and the user is prompted to fully retract the pins 132.

In addition, when the power adapter 10 is in an operating state, the space between the carrier seat 131 and the second housing 112 is kept stable by the repulsive force between the first magnetic member 171 and the second magnetic member 172, so as to prevent the pins 132 from retracting into the receiving space 1111.

Referring to fig. 2, 3, 26 and 32, fig. 32 is a sectional view of a power adapter of another embodiment taken along line a-a of fig. 26. When the power adapter 10 is in the working state, the second magnetic member 172 and the first magnetic member 171 are attracted to each other. The bearing seat 131 includes a guide groove, the second housing 112 includes an end cover 1121, a peripheral side plate 1122 and a guide rail, the end cover 1121 has the through hole 112a, the peripheral side plate 1122 is disposed on the peripheral side of the end cover 1121 and is connected to the end cover 1121 in a bending manner, the guide rail is disposed on the inner wall of the peripheral side plate 1122, the guide rail is matched with the guide groove to limit the movement direction of the bearing seat 131 relative to the second housing 112, the first magnetic member 171 is disposed in the guide groove, and the second magnetic member 172 is disposed on the end cover 1121.

In this embodiment, the guide rail and the guide groove cooperate to limit the movement direction of the bearing seat 131 relative to the second housing 112, so that the bearing seat 131 can move along a preset line (here, a straight line), and the first magnetic member 171 is disposed in the guide groove, so that the space of the bearing seat 131 can be fully utilized, which is beneficial to the miniaturization of the power adapter 10.

When the carrying seat 131 drives the pins 132 to pass through the through holes 112a to the position near the fully extended position, the magnetic attraction force between the first magnetic member 171 and the second magnetic member 172 can quickly drive the carrying seat 131 to continue moving toward the through holes 112a, so that the pins 132 are fully extended, and the power adapter 10 is in the working state. As can be seen from the above description, when the plug 132 is located at a position near the full extension position to the full extension position, the magnetic attraction between the first magnetic member 171 and the second magnetic member 172 of the carrying seat 131 can quickly drive the carrying seat 131 to move toward the through hole 112a, so that the user can feel different hand feeling from other places, and the plug 132 can be prompted to fully extend.

In addition, the second magnetic member 172 is disposed on the end cover 1121, and compared with other positions, the second magnetic member 172 can be better disposed opposite to the first magnetic member 171, so that the attractive force between the first magnetic member 171 and the second magnetic member 172 is stronger, and the effect of quickly driving the bearing seat 131 to move toward the through hole 112a is achieved.

The power adapter 10 further includes a driving assembly 160 and a third magnetic member 173. The driving assembly 160 includes a mounting seat 161 and a driving member 162, which are fixedly connected, and the mounting seat 161 is fixed to the first housing 111. The second housing 112 is sleeved on the mounting seat 161 and can rotate relative to the mounting seat 161, and when the second housing 112 rotates relative to the mounting seat 161, the driving member 162 drives the carrying seat 131 to move. The third magnetic member 173 is disposed on the mounting base 161, and when the power adapter 10 is in the receiving state, the third magnetic member 173 and the first magnetic member 171 are attracted to each other.

When the carrying seat 131 drives the pins 132 to retract into the receiving space 1111 through the through holes 112a, the first magnetic member 171 is driven by the third magnetic member 173, so as to rapidly drive the carrying seat 131 to move in a direction away from the through holes 112a, so that the pins 132 are completely retracted, and the power adapter 10 is in a receiving state. Therefore, when the power adapter 10 is in the vicinity of the storage state, the user can feel a different hand feeling from the other part due to the magnetic attraction between the first magnetic member 171 and the third magnetic member 173, and the user is prompted to fully retract the plug 132.

In addition, when the power adapter 10 is in an operating state, the space between the carrier 131 and the mounting seat 161 is kept stable by the attraction between the first magnetic member 171 and the second magnetic member 172, so that the pins 132 are prevented from protruding into the receiving space 1111.

With reference to the power adapter 10 of any previous embodiment, the housing assembly 110 includes an end surface 112b (see fig. 2 and fig. 3) provided with the through hole 112a, and the end surface 112b forms a plug surface of the power adapter 10.

Referring to fig. 33, fig. 33 is a schematic view illustrating the distance from the edge of the pin to the edge of the end face. When the power adapter 10 is in the working state, the distance from the edge of the pin 132 to the edge of the plugging surface is greater than or equal to 6.5mm, or greater than or equal to 5.1mm, or greater than or equal to 7.9 mm.

The plugging surface 11 of the power adapter 10 is a surface that is mated with the socket 50 when the pins 132 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 132 of the power adapter 10 are inserted into the sockets 50, only the surface that fits into 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 132 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 132 and causing injury to users, a distance d (as shown in fig. 3) between the edge of the pins 132 and the edge of the end surface 112b 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 6.5 mm. 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 7.9 mm. In the schematic diagram of the present embodiment.

The power adapter 10 described in conjunction with the above embodiments, the power adapter 10 further includes a discharging interface 800 (see fig. 3). The discharging interface 800 is electrically connected to the circuit board assembly 120, and is configured to output the second dc voltage converted by the circuit board assembly 120. The discharging interface 800 may be, but is not limited to, a Universal Serial Bus (USB) interface. When the discharging interface 800 is a USB interface, the USB interface may be, but is not limited to, a USB 2.0 interface, a USB 3.0 interface, or the like.
