Referring to fig. 1 and 2, the present application provides a power adapter 100, wherein the power adapter 100 includes a housing 10, a push-pull bracket 20, and pins 30. The housing 10 is provided with an accommodating space 11; the push-pull bracket 20 is in sliding fit with the accommodating space 11; the plug 30 is movably connected to the push-pull bracket 20, and is closed relative to the push-pull bracket 20 and contained in the containing space 11 when sliding to the first position along with the push-pull bracket 20, and is unfolded relative to the push-pull bracket 20 and the end part of the plug is far away from the containing space 11 when sliding to the second position along with the push-pull bracket 20.

It can be understood that, the power adapter 100 may be plugged into a power socket by the pins 30, so that the power adapter 100 may obtain electric energy, thereby conveniently transmitting the electric energy to electronic devices such as a mobile phone, a smart watch, a notebook computer, a tablet computer, and a smart headset. The pins 30 of the power adapter 100 may be pins 30 of various standards such as national standard, european standard, american standard, english standard, australian standard, japanese standard, korean standard, and the like.

Through the sliding fit of the push-pull bracket 20 and the housing 10, the plug pin 30 is movably connected to the push-pull bracket 20, and is accommodated in the accommodating space 11 when sliding to the first position along with the push-pull bracket 20, and the end part of the plug pin is far away from the accommodating space 11 when sliding to the second position along with the push-pull bracket 20, so that the power adapter 100 is fast and convenient to use, labor-saving and safe.

In this embodiment, the housing 10 may protect the push-pull holder 20 and the prongs 30. The housing 10 has a flat box shape to facilitate carrying the power adapter 100. The accommodating space 11 is formed in a space surrounded by the inner surface of the housing 10. The inner surface of the housing 10 slidably guides the push-pull holder 20 so that the push-pull holder 20 can be slid relatively smoothly with respect to the housing 10, i.e., the inner peripheral side surface of the housing 10 is in clearance fit with the outer peripheral side surface of the push-pull holder 20. The first position and the second position are respectively provided at both ends of the housing 10 in the length direction. Of course, in other embodiments, the housing 10 may have a rectangular column shape or a cylindrical shape.

It is understood that, in the present embodiment, the first position and the second position are two end positions of the sliding stroke of the push-pull bracket 20. Specifically, the first position of the housing 10 is determined by that when the push-pull bracket 20 slides to the first position, the plug pins 30 just move along with the push-pull bracket 20 to completely accommodate the accommodating space 11, and the plug pins are completely closed relative to the push-pull bracket 20. In the second position of the housing 10, when the push-pull bracket 20 slides to the second position, the plug pins 30 just move with the push-pull bracket 20 until the end portions of the plug pins completely extend out of the accommodating space 11, and the plug pins are not aligned with the push-pull bracket 20 in a completely unfolded state. In the present embodiment, when the push-pull bracket 20 slides to the first position or the second position, it may be completely or partially accommodated in the accommodating space 11, that is, when the push-pull bracket 20 is at the first position or the second position, the mating state with the accommodating space 11 is limited, and it is necessary to ensure that the plug 30 is in a state of accommodating the accommodating space 11 and closing with respect to the push-pull bracket 20 at one end position (the first position) of the sliding stroke of the push-pull bracket 20, and the end of the plug 30 is away from the accommodating space 11 and is in a state of unfolding with respect to the push-pull bracket 20 at the other end position (the second position) of the sliding stroke of the push-pull bracket 20.

Referring to fig. 2, 3 and 4, in the present embodiment, the push-pull bracket 20 has a first end 21 and a second end 22 opposite to the first end 21. The pin 30 is disposed at the first end 21, the second end 22, or a portion between the first end 21 and the second end 22. The first end 21 is closer to the first position than the second end 22, and the second end 22 is closer to the second position than the first end 21. The direction in which the first end 21 opposes the second end 22 is parallel to the direction in which the first position opposes the second position. The distance from the first end 21 to the second end 22 may be smaller than the distance from the first position to the second position, and may also be larger than the distance from the first position to the second position. The push-pull bracket 20 drives the plug pins 30 to move relative to the housing 10, so that the plug pins 30 can be wholly accommodated in the accommodating space 11 or be wholly away from the accommodating space 11, or the portion of the plug pins connected with the push-pull bracket 20 can be accommodated in the accommodating space, and the end portion of the plug pins far away from the push-pull bracket 20 is far away from the accommodating space 11. When the push-pull bracket 20 is in the first position, the plug pins 30 can be closed relative to the push-pull bracket 20, so that the plug pins 30 and the push-pull bracket 20 are compact in structure, and the plug pins 30 are conveniently accommodated in the accommodating space 11, so that the plug pins 30 are protected by the shell 10, and the safety of the power adapter is ensured. When the push-pull bracket 20 is in the second position, the plug 30 can be unfolded relative to the push-pull bracket 20, so that the plug 30 is away from the accommodating space 11, and the plug 30 can be supported by the push-pull bracket 20 and can be stably plugged on the power supply base. When the plug 30 is unfolded relative to the push-pull bracket 20, the length direction of the plug 30 is perpendicular to the sliding direction of the push-pull bracket 20. The length direction of the pins 30 is the plugging direction of the pins 30 into the power socket. The prongs 30 may be rotatably closed or opened with respect to the push-pull bracket 20, slidably closed or opened with respect to the push-pull bracket 20, or rotatably and slidably closed or opened with respect to the push-pull bracket 20.

It will be appreciated that the structural components of the pin 30 that carry the pivotal connection are subject to high fatigue requirements in order to ensure that the pin 30 is constantly movable relative to the push-pull bracket 20. The pin 30 needs to obtain electric energy when being plugged into the power socket, so the pin 30 is often exposed to arc burning caused by short circuit of a high-voltage circuit, and thus, in order to ensure the safety of the power adapter 100, the structural component for bearing and connecting the pin 30 has high requirements on fire resistance and burning resistance. Obviously, in the embodiment of this application, push-and-pull support 20 bears participating in 30, and push-and-pull support 20 will participate in 30 and completely cut off with shell 10, and push-and-pull support 20 has better insulating barrier propterty, better wear-resisting compressive property compared with shell 10 to and better fire prevention fire behavior, can guarantee power adapter 100's security, increase power adapter 100's life.

The plug pins 30 are movably connected to the push-pull support 20, so that the plug-in connection of the shell 10 and the power socket can be avoided, the shell 10 is prevented from being scratched, the shell 10 is prevented from being damaged, and the appearance performance of the power adapter 100 is ensured. Specifically, the housing 10 is provided with a first end face 16, a second end face 17 opposite to the first end face 16, and a front face 13 connecting the first end face 16 and the second end face 17, the first position and the second position are respectively adjacent to the first end face 16 and the second end face 17, and when the end portions of the pins 30 are far away from the accommodating space 11, the end portions of the pins 30 protrude relative to the front face 13. The housing 10 is further provided with a back side 14 opposite the front side 13 and a first side 15 connected between the front side 13 and the back side 14. When the push-pull bracket 20 moves to the first position, the plug 30 is located between the front surface 13, the back surface 14, the first side surface 15, the first end surface 16 and the second end surface 17, so as to ensure that the plug 30 can be completely accommodated in the accommodating space 11. When the push-pull bracket 20 moves to the second position, the plug 30 may move to the side of the second end surface 17 away from the first end surface 16, so as to be away from the accommodating space 11, and after the plug 30 is unfolded relative to the push-pull bracket 20, the end of the plug protrudes relative to the front surface 13. The pins 30 may also be moved to the side of the second end surface 17 facing the first end surface 16, and the ends of the pins 30 protrude from the front surface 13 away from the accommodating space 11, so that the ends of the pins 30 protrude from the front surface 13 to facilitate the ends of the pins 30 to be plugged into an electrical outlet.

Optionally, the front surface 13 and the back surface 14 are flat surfaces. The distance from the front surface 13 to the back surface 14 is smaller than the distance between the two first side surfaces 15, so that the housing 10 is flat for carrying the power adapter 100.

Optionally, the push-pull bracket 20 is made of an insulating material, and the housing 10 is a metal member or a metal layer is disposed on an outer surface thereof, so that the power adapter 100 is metalized, appearance performance is improved, and safety can be ensured.

Alternatively, after the end of the pin 30 is far away from the accommodating space 11, the pin protrudes relative to the front surface 13, and the length direction of the pin 30 is perpendicular to the front surface 13.

Specifically, the push-pull bracket 20 has a first surface 23, a second surface 24 opposite to the first surface 23, and two second side surfaces 25 connected between the first surface 23 and the second surface 24 and oppositely disposed. The first surface 23, the second surface 24 and the two second sides 25 form the peripheral sides of the push-pull bracket 20. The first surface 23 and the second surface 24 are adjacent to the front surface 13 and the back surface 14, respectively. The prongs 30 are deployed from the first surface 23 or closed to the push-pull bracket 20. The two second sides 25 may be located on the left and right sides of the push-pull bracket 20. The first surface 23, the second surface 24 and the second side 25 are all clearance fitted with the inner peripheral side of the housing 10 to ensure that the push-pull bracket 20 can slide relative to the housing 10.

Optionally, the push-pull bracket 20 includes a first housing 26 and a second housing 27 covering the first housing 26, and the portion of the plug 30 movably connected to the push-pull bracket 20 is disposed between the first housing 26 and the second housing 27. The first surface 23 is formed on a surface of the first housing 26 facing away from the second housing 27, and the second surface 24 is formed on a surface of the second housing 27 facing away from the first housing 26. A portion of the pin 30 is held by the first and

second housings

26 and 27, so that the pin 30 smoothly moves with respect to the push-pull bracket 20. The side 25 is formed by splicing the first housing 26 and the second housing 27, that is, half of the side 25 is formed at the edge of the first housing 26, and the other half is formed at the edge of the second housing 27. By detachably connecting the first casing 26 and the second casing 27, the plug pins 30 can be conveniently detached and maintained, and the service life of the power adapter 100 is prolonged.

It is understood that, in the present embodiment, the driving force for sliding the push-pull bracket 20 relative to the housing 10 may be a manual force of a user, that is, the user manually acts on the push-pull bracket 20 and the housing 10 to make the two slide relative to each other. The unfolding motion of the plug 30 relative to the push-pull bracket 20 can be driven by a driving element disposed on the push-pull bracket 20, i.e. the plug 30 can be unfolded relative to the push-pull bracket by the driving force of the driving element when the push-pull bracket 20 slides to the second position.

In the first embodiment, the first end surface 16 is disposed in a closed manner, and the second end surface 17 is disposed with an opening 111 communicating with the accommodating space 11. When the push-pull bracket 20 slides to the first position, the push-pull bracket 20 is accommodated in the accommodating space 11, and when the push-pull bracket 20 slides to the second position, a portion of the push-pull bracket 20 extends out through the opening 111. During the process of assembling the push-pull bracket 20 with the housing 10, the push-pull bracket 20 can be at least partially inserted into the accommodating space 11 through the opening 111 to realize the sliding fit between the push-pull bracket 20 and the housing 10. The first end 21 is always in plug-in fit with the housing 10, and the second end 22 can be retracted or extended relative to the housing 10. When the second end 22 extends out of the opening 111, and finally the plug 30 moves along with the push-pull bracket 20 in the process of moving the push-pull bracket 20 to the second position, the plug 30 can be unfolded relative to the push-pull bracket 20, and finally the end of the plug 30 is far away from the push-pull bracket 20 and further far away from the accommodating space 11, so that the end of the plug 30 is convenient to be plugged into a power socket. When the second end 22 is retracted into the opening 111, and finally the push-pull bracket 20 moves to the first position, the plug pins 30 move to the position of being accommodated in the accommodating space 11 along with the push-pull bracket 20, and the plug pins 30 are restricted by the housing 10 and cannot move relative to the push-pull bracket 20, so that the power adapter 100 has a more compact structure and a smaller and more compact appearance after the plug pins 30 are accommodated in the housing 10, and the housing 10 protects the plug pins 30. It can be understood that, in the process that the plug 30 is accommodated in or away from the accommodating space 11, only the push-pull bracket 20 needs to be driven to slide relative to the housing 10, and the push-pull bracket 20 is linked with the plug 30 without contacting the plug 30, so that the plug 30 is prevented from being damaged, and the safety of the plug 30 is ensured. It is understood that the movement of the prong 30 relative to the push-pull bracket 20 may be accompanied by the sliding movement of the push-pull bracket 10 relative to the housing 10, or the movement of the prong 30 relative to the push-pull bracket 20 may be followed by the sliding movement of the push-pull bracket 10 relative to the housing.

Optionally, the opening 111 is a rectangular hole, that is, the space where the accommodating space 11 is in sliding fit with the push-pull bracket 20 is a rectangular space, so as to limit the push-pull bracket 10 and prevent the push-pull bracket 20 from rotating relative to the housing 10.

In the first embodiment, the front surface 13 is provided with a through hole 12 communicating the opening 111 and the accommodating space 11, and when the push-pull bracket 20 slides to the second position, the end of the pin 30 is far away from the accommodating space 11 from the through hole 12. The through-hole 12 is opened at the front face 13 connecting the second end face 17 so that the through-hole 12 communicates with the opening 111. Through opening the through hole 12 in the front 13, pulling the push-pull bracket 20 to stretch out the accommodating space 11 from the opening 111, so that the push-pull bracket 20 does not need to take the plug 30 out of the accommodating space 11 completely, and only needs to drive the plug 30 to a position corresponding to the through hole 12, so that the end of the plug 30 can stretch out of the through hole 12, and finally the end of the plug 30 is far away from the accommodating space 11, that is, the push-pull bracket 20 slides to the second position. In a state that the end of the plug pin 30 is far away from the accommodating space 11, by pushing the push-pull bracket 20 to contract towards the accommodating space 11, the plug pin 30 may start to close relative to the push-pull bracket 20, and gradually stagger relative to the through hole 11 as the push-pull bracket 20 slides, and finally, the plug pin 30 slides in a state of being resisted and limited by the housing 10, and the second end 22 of the push-pull bracket 20 covers the opening 111, that is, the push-pull bracket 20 slides to the first position. When the push-pull bracket 20 slides to the first position, the push-pull bracket 20 can be accommodated in the accommodating space 11, and the end surface of the second end 22 is flush with the second end surface 17, so as to ensure the appearance smoothness of the power adapter 100. In other embodiments, when the push-pull bracket 20 slides to the first position, a portion of the second end 22 of the push-pull bracket 20 may be exposed from the opening 111 to form a receiving space, so that a pulling force is applied to the portion of the push-pull bracket 20 exposed from the opening 111 next time, thereby facilitating the sliding of the push-pull bracket 20 relative to the housing 10.

In the first embodiment, referring to fig. 5 and 6, the push-pull bracket 20 is provided with a boss 29 engaged with the through hole 12, when the push-pull bracket 20 slides to the first position, the boss 29 abuts against the inner wall of the through hole 12 away from the opening 111 to limit the push-pull bracket 20.

Specifically, referring to fig. 6, 7 and 8, the front surface 13 has two inner side edges 132 connected to the second end surface 17, and a supporting edge 133 connected to the two inner side edges 132 and opposite to the second end surface 17, and the through hole 12 is formed among the second end surface 17, the two inner side edges 132 and the supporting edge 133.

When the push-pull bracket 20 drives the plug pin 30 to be accommodated in the accommodating space 11, that is, when the push-pull bracket 20 slides to the first position, the boss 29 abuts against the abutting edge 133 to limit the push-pull bracket 20 to be inserted into the accommodating space 11, so as to prevent the push-pull bracket 20 from being excessively retracted into the accommodating space 11, which is inconvenient for pulling out the push-pull bracket 20 from the accommodating space 11 next time.

When the push-pull bracket 20 drives the end of the plug pin 30 to be far away from the accommodating space 11, that is, when the push-pull bracket 20 slides to the second position, a part of the boss 29 is matched with the through hole 12, and the boss 29 can fill a part of the through hole 12, so as to avoid impurities from being mixed in the through hole 12, and ensure the appearance smoothness of the power adapter 100. When the push-pull bracket 20 slides to the first position, the side surface of the boss 29 near the first end 21 can abut against the abutting edge 133, so as to prevent the push-pull bracket 20 from retracting into the opening 111 and being unable to pull the push-pull bracket 20 next time. The two inner edges 132 can also be slidably engaged with two side walls of the boss 29 to slidably guide the push-pull bracket 20.

Optionally, the top surface of the boss 29 may be flush with the front surface 13 to ensure the flatness of the appearance of the power adapter 100. The top surface of the boss 29 and the front surface 13 are allowed to have a certain assembly tolerance, ensuring that the top surface of the boss 29 always preferentially contacts the power socket with the front surface 13, thereby preventing the outer surface of the housing 10 from being damaged.

Optionally, the top surface of the boss 29 protrudes relative to the front surface 13, so that when the pin 30 is plugged into the power socket, a certain distance is always reserved between the housing 10 and the power socket, so as to ensure the safety of the housing 10.

It will be appreciated that when the push-pull bracket 20 is slid to the second position, the prong 30 is just no longer constrained by the housing 10, the prong 30 can receive the driving force to start to unfold movably relative to the push-pull bracket 20 and finally unfold to a state where its end portion protrudes out of the through hole 12, and the portion of the prong 30 connected to the push-pull bracket 20 is close to the abutting edge 133. When the plug 30 needs to be accommodated in the accommodating space 11, the push-pull bracket 20 is pushed to slide towards the first end surface 16, and the abutting edge 133 abuts against the peripheral side surface of the plug 30, so as to force the plug 30 to close relative to the push-pull bracket 20, and gradually begin to shrink into the accommodating space 11, finally the plug 30 moves to a state of closing with the push-pull bracket 20, and the plug 30 shrinks into the accommodating space 11.

In a first embodiment, referring to fig. 5 and 6, the plug 30 can be rotatably opened or closed relative to the push-pull bracket 20, i.e., the plug 30 is rotatably connected to the push-pull bracket 20.

Specifically, the push-pull support 20 is further provided with receiving grooves 210 located at two sides of the boss 29, the pin 30 is provided with a rotating shaft 31 and two pin columns 32 fixed on the rotating shaft 31, the rotating shaft 31 is rotatably connected with the push-pull support 20 and penetrates through the two receiving grooves 210, the axial direction of the rotating shaft 31 is perpendicular to the sliding direction of the push-pull support 20, and the two pin columns 32 can rotate along with the rotating shaft 31 and are respectively rotatably screwed out of or screwed into the two receiving grooves 210. The rotating shaft 31 is sandwiched between the first and

second housings

26 and 27 so that the prongs 30 can effectively rotate relative to the push-pull bracket 20.

In this embodiment, the boss 29 has a "T" shape. The portion of the boss 29 perpendicular to the sliding direction of the push-pull bracket 20 is near the second end 22 of the push-pull bracket 20. The portion of the boss 29 parallel to the sliding direction of the push-pull bracket 20 is located between the two receiving grooves 210. When the plug 30 is rotated out relative to the push-pull bracket 20 and the housing 10, the end of the plug 30 connected to the push-pull bracket 20 is located in the receiving groove 210, and the other end is located outside the receiving groove 210. The pin columns 32 are accommodated in the accommodating grooves 210, so that the pins 30 are closed relative to the push-pull support 20, the push-pull support 20 can hide and protect the pins 30, and the size of the power adapter 100 (see fig. 1) is reduced, so that the power adapter is convenient to carry.

Specifically, the longitudinal direction of the pin 32 is perpendicular to the longitudinal direction of the rotating shaft 31. The center axis of the pin column 32 intersects with the center axis of the rotary shaft 31. The two pin columns 32 are arranged side by side in the axial direction of the rotating shaft 31. A part of the rotating shaft 31 is always positioned in the receiving groove 210. The rotating shaft 31 is adjacent to the receiving groove 210 and away from the first end surface, so that the end of the pin 32 away from the rotating shaft 31 can be turned out of the receiving groove 210. When the plug 30 is in a closed state relative to the push-pull bracket 20, the bottom wall of the receiving groove 210 limits the plug 30 to prevent the plug 30 from being excessively contracted into the push-pull bracket 20. When the plug pins 30 are in the unfolded state relative to the push-pull bracket 20, the accommodating grooves 210 limit the plug pins 30 by the side walls of the rotating shafts 31, so as to prevent the plug pins 30 from being inserted into the power supply socket disadvantageously due to an excessively large overturning included angle relative to the push-pull bracket 20. The two receiving grooves 210 are used for respectively receiving the two pin columns 32, so that the stability of the push-pull support 20 is increased, the two pin columns 32 can be effectively isolated, and the short circuit of the pin columns 32 is prevented. The pin post 32 is a metal piece to enable the pin 30 to draw current.

In the first embodiment, a bearing boss is formed in the first housing 26 corresponding to the receiving groove 210 and facing the second housing 27, and a bearing protrusion 271 mating with the bearing boss is disposed in the second housing 27 facing the first housing 26. The bearing boss is provided with a first U-shaped groove, and the bearing boss 271 is provided with a second U-shaped groove. The first and second U-shaped grooves together carry the pivot shaft 31 of the prongs 30, enabling the prongs 30 to be flipped relative to the push-pull support 20. The first U-shaped groove communicates with the inner space of the push-pull holder 20 and the receiving groove 210. Two first U-shaped grooves are respectively formed on two side walls of the bearing boss, so that the rotating shaft 31 passes through the accommodating groove 210 through the first U-shaped grooves, and the pin post 32 is fixed on a portion of the rotating shaft 31 passing through the accommodating groove 210. The second housing 27 is provided with four bearing protrusions 271 corresponding to the four second U-shaped grooves to increase the structural stability of the rotating shaft 31 and the push-pull bracket 20, ensure that the rotating shaft 31 rotates smoothly relative to the push-pull bracket 20, and effectively isolate the two pin columns 32.

Referring to fig. 7 and 8, the pin post 32 has a root 321 fixedly connected to the rotating shaft 31, the pin 30 further has an insulating block 33 covering the periphery of the root 321, when the push-pull bracket 20 is inserted into the end plate 16 to slide, the abutting edge 133 abuts against the insulating block 33 and pushes the insulating block 33 to screw into the receiving slot 210, so as to push the pin into the receiving slot 210. When the push-pull bracket 20 slides from the second position to the first position, the housing 10 abuts against the insulating block 33 and pushes the insulating block 33 to screw into the receiving slot 210, so as to push the pin post 32 into the receiving slot 210. It is understood that the abutting edge 133 is a portion of the housing 10 that abuts against the insulating block 33.

The insulating block 33 covers the root portion 321, and covers a portion of the rotating shaft 31 connected to the root portion 321. The insulating block 33 has a flat end surface 331 perpendicular to the longitudinal direction of the pin 32 and a circular arc end surface 332 opposite to the flat end surface 331. The pin column 32 passes through the flat end surface 331. When the pin post 32 is in the final state of being rotated out of the receiving slot 210, the flat end surface 331 is substantially flush with the top surface of the boss 29. The arc end surface 332 is an arc cylindrical surface. The center axis of the circular arc end surface 332 coincides with the center axis of the rotary shaft 31. The insulating block 33 also has an abutment side surface 333 connecting the flat end surface 331 and the arc end surface 332. The abutment side surface 333 is perpendicular to the flat end surface 331 and tangential to the arcuate end surface 332. The abutting side surface 333 is provided on the side of the insulating block 33 close to the abutting edge 133. When the end of the pin 30 is far away from the receiving space 11, the abutting side 333 is adjacent to the abutting edge 133. When the end of the pin post 32 has been screwed out of the receiving slot 210, the push-pull bracket 20 slides relative to the housing 10 under the driving force and slides in a manner of gradually closing to the first position, the abutting edge 133 starts to abut against the abutting side surface 333, so that the insulating block 33 receives the sliding resistance from the housing 10, the insulating block 33 starts to drive the pin post 32 to rotate into the receiving slot 210 under the sliding resistance of the housing 10, and the abutting side surface 333 gradually slides into the receiving space 11 in a sliding fit with the abutting edge 133, so that the pin post 32 is finally received in the receiving slot 210, and at this time, the pin post 32 moves to a state of being located in the receiving space 11, and a part of the pin post 32 is staggered with a region corresponding to the through hole 12, so that the pin 30 can rotate out of the receiving slot 210 when the push-pull bracket 20 is driven to slide relative to the housing 10 next time. Of course, in another embodiment, the insulating block 33 may have a cylindrical shape, the arc end surface 332 may be an arc spherical surface, and the contact side surface 333 may be a circular cylindrical surface.

In the first embodiment, the housing 10 is provided with a chamfered surface 134 at the abutting edge 133, and the chamfered surface 134 is slidably engaged with the abutting side surface 333 of the insulating block 33 when the push-pull holder 20 is slid to the second position.

In the present embodiment, the housing 10 is provided with a through hole inner surface 135 connected to the front surface 13, and the through hole inner surface 135 faces the second end surface 17. A through-hole inner side surface 135 is formed at the abutting edge 133, and a chamfered surface 134 is provided between the through-hole inner side surface 135 and the inner surface of the housing 10. When the push-pull holder 20 is inserted and slid to the second position, the chamfered surface 134 contacts the abutment side surface 333, the chamfered surface 134 is in contact with the abutment side surface 333, the abutment side surface 333 slides relative to the chamfered surface 134, and the abutment side surface 333 rotates relative to the chamfered surface 134. The chamfered surface 134 and the abutting side surface 333 are used for matching to reduce the sliding resistance between the housing 10 and the insulating block 33, so as to ensure that the housing 10 pushes the insulating block 33 to smoothly rotate towards the push-pull bracket 20, i.e. ensure the smoothness of the pin 30 screwed into the receiving slot 210. Optionally, the chamfered surface 134 is an arc surface, and the chamfered surface 134 is tangent to the inner side surface 135 of the through hole and the inner surface of the housing 10. Of course, in other embodiments, the through-hole inner surface 135 is an arc surface, the through-hole inner surface 135 is tangent to the outer surface of the housing 10 and the inner surface of the housing 10, and the chamfered surface 134 is formed at the connection point of the through-hole inner surface 135 and the inner surface of the housing 10. When the push-pull bracket 20 is inserted and slid toward the end plate 16, the inner side surface 135 of the through hole is slidably engaged with the side surface 25 of the insulating block 33.

In the second embodiment, please refer to fig. 9 and 10, which are substantially the same as the first embodiment, except that when the push-pull bracket 20 slides to the second position, the end of the plug 30 is driven to move away from the accommodating space 11 from the opening 111.

Specifically, when the push-pull bracket 20 slides to the second position, the plug pin 30 is completely pulled out from the accommodating space 11, so that the plug pin 30 is completely located outside the accommodating space 11, and the plug pin 30 is not limited by the housing 10, the plug pin 30 can receive driving force and move to the unfolded state relative to the push-pull bracket 20, and the end of the plug pin 30 protrudes relative to the front surface 13, so that the plug pin 30 is conveniently plugged with the power socket. When the push-pull bracket 20 slides to the first position, the push-pull bracket 20 drives the plug pins 30 to enter the accommodating space 11 from the opening 111, so that at least part of the plug pins 30 are accommodated in the accommodating space 11, and thus the plug pins 30 are limited by the housing 10, and the plug pins 30 cannot be unfolded relative to the push-pull bracket 20 to keep a closed state with the push-pull bracket 20, so that the power adapter 100 is compact in structure and convenient to carry.

It will be appreciated that the prongs 30 extend from the openings 111 and allow the prongs 30 to move to a deployed position relative to the push-pull support 20, such that the housing 10 is structurally complete and the front 13 and back 14 surfaces conform, ensuring the structural appearance of the housing 10.

More specifically, in order to facilitate the push-pull bracket 20 to be inserted into the accommodating space 11 and ensure that the front surface 13 is consistent with the back surface 14, the first surface 23 and the second surface 24 are both flat, so as to ensure that the first surface 23 and the second surface 24 can be slidably engaged with the inner surface of the housing 10.

In order to facilitate the pushing of the pin 30 to rotate in a closing manner relative to the push-pull bracket 20 by using the housing 10, the first end surface is provided with a chamfered surface 134 at an edge adjacent to the opening 111, the chamfered surface 134 is close to the front surface, so that the chamfered surface 134 contacts and abuts against the side surface 333, and further, by applying a driving force to the push-pull bracket 20 to move from the second position to the first position, the housing 10 applies a pushing force to the pin 30 in a direction from the first end to the second end, so that the pin 30 can rotate in a closing manner relative to the push-pull bracket 20.

It will be appreciated that to facilitate the housing 10 being able to push the prongs 30 closed against the push-pull support 20, the portion of the prongs 30 that are connected to the push-pull support 20 may be spaced from the second end 22 of the push-pull support 20 such that the closed prongs 30 are positioned within the distance, and the portion of the prongs 30 that are connected to the push-pull support 20 may also be adjacent the second end 22 if the prongs 30 are not required to be closed against the push-pull support 20 by the pushing force of the housing 10.

In a third embodiment, please refer to fig. 11 and 12, which are substantially the same as the first embodiment, except that the first end surface 16 is provided with an opening 111 communicated with the accommodating space 11, the second end surface 17 is closed, the front surface 13 is provided with a through hole 12 communicated with the accommodating space 11 and adjacent to the second end surface 17, when the push-pull bracket 20 slides to the first position, a part of the push-pull bracket 20 extends through the opening 111, and when the push-pull bracket 20 slides to the second position, the push-pull bracket 20 is accommodated in the accommodating space 11.

In particular, the pin 30 is movably connected to the second end 22. When the push-pull bracket 20 is slid to the second position, the second end 22 is adjacent to the second end surface 17, the pin 30 can correspond to the through hole 12, the pin 30 can be movably unfolded relative to the push-pull bracket 20, and the end part of the pin 30 can extend out of the through hole 12, so that the end part of the pin 30 protrudes relative to the front surface 12. When the push-pull bracket 20 is slid to the first position, the second end 22 is offset from the through hole 12, so that the plug 30 is at least partially offset from the through hole 12, and the plug 30 is at least partially restrained by the housing 10, so that the plug 30 cannot move relative to the push-pull bracket 20, thereby keeping the closed state relative to the push-pull bracket 20, and the first end 21 of the push-pull bracket 20 extends out of the opening 111. After the first end 21 extends out of the opening 111, the first end 21 is pressed next time, so that the push-pull bracket 20 is driven to slide towards the second end surface 17, and then the push-pull bracket 20 slides to the second position, so that the end of the plug 30 is far away from the accommodating space 11. When the plug 30 needs to be accommodated in the accommodating space 11, a pulling force away from the second end surface 17 is applied to the push-pull bracket 20, so that the plug 30 is away from the second end surface 17, gradually retracts from the through hole 12 to the accommodating space 11, and is closed relative to the push-pull bracket 20.

Optionally, in order to fully utilize the usage space of the push-pull bracket 20, the receiving slot 210 may be used to receive devices such as a circuit board, a transformer, and an electronic component between the position adjacent to the first end 21 and the pin 30, so that the power adapter 100 has a compact structure, and the devices such as the circuit board, the transformer, and the electronic component are more conveniently electrically connected to the pin 30.

In the fourth embodiment, please refer to fig. 13 and 14, which are substantially the same as the third embodiment, except that the first end surface 16 and the second end surface 17 are both closed, the push-pull bracket 20 is always accommodated in the accommodating space 11, the front surface 13 is provided with a through hole 12 adjacent to the second end surface 17, and when the push-pull bracket 20 slides to the second position, the end of the pin 30 is far away from the accommodating space 11 through the through hole 12.

Specifically, the push-pull bracket 20 slides back and forth between the first end surface 16 and the second end surface 17, and the pin 30 is movably connected to the second end 22. When the push-pull bracket 20 slides to the first position, the first end 21 is adjacent to the first end surface 16, the second end 22 is spaced from the second end surface 17, the second end 22 is staggered with respect to the through hole 12, and the pin 30 is staggered with respect to the through hole 12, so that the pin 30 is limited by the housing 10, maintains a closed state with the push-pull bracket 20, and is accommodated in the accommodating space 11. When the push-pull bracket 20 slides to the second position, the second end 22 is adjacent to the second end surface 17, the pin 30 corresponds to the through hole 12, the end portion thereof protrudes from the through hole 12 to be far away from the accommodating space 11, and the first end 21 is spaced from the first end surface 16. The first end face 16 and the second end face 17 are both closed, so that a larger part of the push-pull support 20 is always accommodated in the accommodating space 11, and the safety of the push-pull support 20 is ensured. The push-pull bracket 20 may be provided with a portion of the push-pull structure extending from the first side 15 (see fig. 2), the front 13 or the back 14 so as to receive a driving force by the push-pull structure to drive the push-pull bracket 20 to slide relative to the housing 10. Of course, a driving mechanism may be disposed in the accommodating space, and the driving mechanism may be used to directly drive the push-pull bracket to slide relative to the housing.

In the fifth embodiment, please refer to fig. 15 and 16, which are substantially the same as the second embodiment, except that the first end surface 16 and the second end surface 17 are both provided with an opening 111 communicated with the accommodating space 11, when the push-pull bracket 20 slides to the first position, a portion of the push-pull bracket 20 extends through the opening of the first end surface 16, and when the push-pull bracket 20 slides to the second position, a portion of the push-pull bracket 20 extends through the opening of the second end surface 17.

Specifically, the push-pull bracket 20 always at least partially protrudes out of the accommodating space from the opening 111. When the push-pull bracket 20 slides to the first position, the first end 21 extends out from the opening of the first end surface 16, the second end 22 is accommodated in the accommodating space 11, the pin 30 is accommodated in the accommodating space 11 and is adjacent to the second end surface 17, and the first end 21 extends out from the opening 111 of the first end surface 16, so that the push-pull bracket 20 receives the pushing force and slides towards the second end surface 17. When the push-pull bracket 20 slides to the second position, the second end 22 extends out of the opening 111 of the second end surface 17, the pin 30 is far away from the accommodating space 11 from the opening 111, and the end part of the pin protrudes relative to the front surface 13, and the first end 21 is accommodated in the accommodating space 11. The first end face 16 and the second end face 17 are provided with the opening 111, so that the push-pull support 20 always partially extends out of the opening 111, the part of the push-pull support 20 extending out of the opening 111 receives driving force and slides relative to the housing 10, the push-pull support 20 is prevented from exposing the accommodating space 11 from the front face 13, the back face 14 and the first side face 15, and the appearance integrity of the front face 13, the back face 14 and the first side face 15 is ensured.

Further, referring to fig. 17, the power adapter 100 further includes a power assembly 40, the power assembly 40 is accommodated in the accommodating space 11, and the power assembly 40 is connected to the plug 30 and the push-pull bracket 20, so as to drive the plug 30 to move relative to the push-pull bracket 20.

In the present embodiment, the power module 40 is always housed in the casing 10. The power assembly 40 may drive the prong 30 to expand relative to the push-pull bracket 20 while using other components to drive the prong 30 to close relative to the push-pull bracket 20. The power assembly 40 may be configured to drive the prongs 30 to either expand relative to the push-pull bracket 20 or to drive the prongs 30 to close relative to the push-pull bracket 20. The power assembly 40 may drive only the prongs 30 to close relative to the push-pull bracket 20 while using other components to drive the prongs 30 to expand relative to the push-pull bracket 20. The power assembly 40 can drive the plug 30 to rotate relative to the push-pull bracket 20, can drive the plug 30 to slide relative to the push-pull bracket 20, and can drive the plug 30 to rotate and slide relative to the push-pull bracket 20. The power adapter 100 of the present application is not limited to the manner in which the power assembly 40 drives the prongs 30 to move relative to the push-pull bracket 20.

In a first embodiment, referring to fig. 17 and 18, the power assembly 40 can continuously provide a rotational torque to the prong 30 to drive the prong 30 to rotatably deploy relative to the push-pull bracket.

Specifically, the power assembly 40 provides a power torque to the prongs 30 such that the prongs 30 may flip relative to the push-pull bracket 20 and assume a deployed state. The power assembly 40 can always provide torque for the plug pin 30, when the push-pull bracket 20 moves to the second position, the plug pin 30 moves along with the push-pull bracket 20 to a position corresponding to the through hole 12, so that the plug pin 30 can release after receiving the torque of the power assembly 40, and further the plug pin 30 can rotate and expand relative to the push-pull bracket 20, and finally the end part of the plug pin is far away from the accommodating hole 11. In the process of accommodating the plug 30 in the accommodating space 11, by pushing the push-pull support 20 to slide to the first position, the chamfered surface 134 of the housing 10 starts to contact with the plug 30 and forces the plug 30 to close relative to the push-pull support 20 and gradually retract towards the accommodating space 11, finally the plug 30 moves to the position pressed and limited by the housing 10, the plug 30 is limited by the housing 10 and cannot release the rotation torque, and thus the stationary state relative to the push-pull support 20 is maintained, that is, the closing of the plug 30 relative to the push-pull support 20 is completed by the pressing and limiting acting force of the housing 10.

Optionally, the power assembly 40 is provided with a torsion spring 41, one end of the torsion spring 41 is fixedly connected with the plug pin 30, and the other end of the torsion spring 41 is fixedly connected with the push-pull bracket 20, so as to provide torque for unfolding and rotating the plug pin 30 relative to the push-pull bracket 20.

The torsion spring 41 has a first fixed end 411 and a second fixed end 412 opposite to the first fixed end 411, and a bending arm 413 connected between the first fixed end 411 and the second fixed end 412. The first fixing end 411 is fixed to the connection pin 30, and the second fixing end 412 is fixed to and abutted against the inner side of the second housing 27. The second fixing end 412 is located in the clip groove 262. The curved arm 413 is wound around the rotation shaft 31. The bent arm 413 provides an elastic force for the first fixing end 411 to be spread relative to the second fixing end 412. When the housing 10 pushes the plug 30 to screw into the accommodating space 11, the bending arm 413 is deformed by the twisting action force, the torsion spring 41 starts to store kinetic energy, and the first fixed end 411 and the second fixed end 412 of the torsion spring 41 are in a mutually closed state. When the push-pull bracket 20 drives the plug 30 to slide to a position corresponding to the through hole 12, the plug 30 is not limited by the housing 10, and the torsion spring 41 releases kinetic energy to the plug 30, so that the plug 30 rotates relative to the push-pull bracket 20 and is screwed out of the accommodating space 11.

Specifically, the power assembly 40 further has a shaft sleeve 42 for fixedly connecting the plug 30, and the torsion spring 41 is sleeved on the shaft sleeve 42, and has one end fixed to the peripheral wall of the shaft sleeve 42 and the other end fixed to the push-pull bracket 20. The sleeve 42 is fitted over the end of the rotating shaft 31. Alternatively, the end of the rotating shaft 31 is provided with a flat pin 310, and the flat pin 310 protrudes axially along the rotating shaft 31. The shaft sleeve 42 is provided with a flat insertion hole, and the flat insertion hole extends inwards along the axial direction of the shaft sleeve 42. The flat pin 310 is engaged with the flat insertion hole to prevent the boss 42 from rotating with respect to the rotation shaft 31 and to stabilize the boss 42 with the rotation shaft 31. A pin hole is formed in the circumference of the shaft sleeve 42, the first fixed end 411 is inserted into the pin hole, and the bent arm 413 is wound around the circumference of the shaft sleeve 42 so that the first fixed end 411 is fixed to the rotating shaft 31. The shaft sleeve 42 is detachably connected with the rotating shaft 31, so that the power assembly 40 and the plug pins 30 can be detachably maintained, and the service life of the power adapter 100 can be prolonged.

A sixth embodiment is provided and referring to fig. 19, substantially the same as the first embodiment except that the power assembly 40 continues to provide rotational torque to the prongs 30 to cause the prongs 30 to rotate in a closed relationship relative to the push-pull bracket 20. When the push-pull bracket 20 slides to the first position, the power assembly 40 drives the plug 30 to close relative to the push-pull bracket 20, and the plug 30 is gradually accommodated in the accommodating space 11. When the end of the plug 30 needs to be far away from the accommodating space 11, the push-pull bracket 20 is driven to slide to the second position relative to the shell 10, the plug 30 is abutted by the abutting edge of the shell 20, so that the plug 30 is unfolded and rotated relative to the push-pull bracket 20, and finally, the end of the plug 30 extends out of the through hole 12 and is far away from the accommodating space 11.

Optionally, the power assembly 40 is provided with a closing torsion spring 410, one end of the closing torsion spring 410 is fixedly connected with the plug pin 30, and the other end of the closing torsion spring is fixedly connected with the push-pull bracket 20, so as to drive the plug pin 30 to close relative to the push-pull bracket 20. When the plug 30 is unfolded relative to the push-pull bracket 20, the two ends of the closing torsion spring 410 are elastically unfolded, as shown in the figure, so that the plug 30 is driven by the driving force towards the closing of the push-pull bracket 20, and when the plug 30 is not limited by the shell, the plug 30 starts to rotate relative to the push-pull bracket 20 under the elastic closing force of the closing torsion spring 410.

A seventh embodiment is provided and referring to fig. 20 and 21, substantially identical to the first embodiment except that the power assembly 40 can drive the prongs 30 to either extend or close relative to the push-pull bracket 20. During the sliding process of the push-pull bracket 30 from the second position to the first position, the power assembly 40 drives the plug 30 to rotate relative to the push-pull bracket 20. During the sliding process of the push-pull bracket 30 from the first position to the second position, the power assembly 40 drives the plug 30 to unfold and rotate relative to the push-pull bracket 20.

Specifically, referring to fig. 22, 23 and 24, the power assembly 40 is provided with a first magnetic member 49 fixedly connected with the plug 30 and a second magnetic member 48 fixedly connected with the housing, when the push-pull bracket 20 slides to the second position, the first magnetic member 49 and the second magnetic member 48 are in magnetic repulsion engagement to drive the plug 30 to rotate and unfold relative to the push-pull bracket 20, and the end portion thereof is far away from the accommodating space 11. When the push-pull bracket 20 slides to the first position, the first magnetic member 49 and the second magnetic member 48 are magnetically engaged to drive the plug 30 to rotate and close relative to the push-pull bracket 20.

Referring to fig. 23, 24, 25 and 26, unlike the first embodiment, the shaft sleeve 42 is provided with a first fixing groove 429, an opening of the first fixing groove 429 is located on the circumferential side of the shaft sleeve 42, and an opening direction of the first fixing groove 429 is perpendicular to the length direction of the pin 30. The first magnetic member 49 is fixed in the first fixing groove 429, and the first magnetic member 49 is offset from the axis of the rotating shaft 31, so that the rotating shaft 31 can be driven by the first magnetic member 49 to rotate. The first magnetic member 49 is provided with a first south magnetic pole 491 and a first north magnetic pole 492, the relative directions of the first south magnetic pole 491 and the first north magnetic pole 492 being perpendicular to the axial direction of the rotating shaft 31 and parallel to the longitudinal direction of the pin 32. The first south magnetic pole 491 and the first north magnetic pole 492 are each partially exposed out of the first fixing groove 429 so that the first south magnetic pole 491 and the first north magnetic pole 492 are each magnetically engageable with the second magnetic member 48. The inner surface of the housing 10 adjacent to the back surface 14 is provided with a second fixing groove 149, and the second magnetic member 48 is fixed to the second fixing groove 149. The second magnetic member 48 is provided with a second south magnetic pole 481 and a second north magnetic pole 482. The opposing directions of the second south magnetic pole 481 and the second north magnetic pole 482 are perpendicular to the front face. The second north magnetic pole 482 is at least partially exposed from the second retaining groove 149 to facilitate magnetic engagement of the second north magnetic pole 482 with the first south magnetic pole 491 and the first north magnetic pole 492.

Optionally, the outer shell 10 is provided with a retaining plate 148 at two ends of the second fixing groove 149 parallel to the sliding direction of the push-pull bracket 20, and the retaining plate 148 clamps the second magnetic member 48 firmly to ensure the stability of the second magnetic member 48 and the outer shell 10.

Optionally, the two ends of the rotation shaft 31 of the pin 30 are provided with the shaft sleeves 42, and the first magnetic members 49 are fixed in the two shaft sleeves 42, so as to increase the rotational balance of the pin 30.

Optionally, two second magnetic members 48 are disposed in the housing 10, and the two second magnetic members 48 are respectively matched with the two first magnetic members 49.

To facilitate the magnetic engagement of the first magnetic member 49 and the second magnetic member 48, the second surface 24 of the push-pull bracket 20 is provided with a sliding through-slot 249 corresponding to the bushing 42. The sliding channel 249 is in sliding engagement with a portion of the second magnetic member 48 such that the second magnetic member 48 can exert a magnetic force on the first magnetic member 49.

The magnetic force of the first magnetic member 49 and the second magnetic member 48 is used to drive the plug 30 to rotate in an opening or closing manner with respect to the push-pull bracket 20.

The first south magnetic pole 491 is close to the end of the pin 32 which can be far away from the accommodating space 11 relative to the first north magnetic pole 492. The second south magnetic pole 481 is adjacent the back face 14 relative to the second north magnetic pole 482. As shown in fig. 23, when the push-pull bracket 20 slides to the first position, the first south magnetic pole 491 and the first north magnetic pole 492 are opposite and parallel to the front surface 13, and the second magnetic member 48 is located on the side of the rotating shaft 32 adjacent to the first end 21, i.e. the second north magnetic pole 482 and the first south magnetic pole 491 are close to each other, so that the second north magnetic pole 482 and the first south magnetic pole 491 are kept magnetically attracted, and the rotating moment closing with respect to the push-pull bracket 20 is continuously applied to the pin 30. As shown in fig. 24 and fig. 25, when the end of the plug 30 needs to be away from the accommodating space 11 so as to be plugged into the power socket by using the plug 30, the push-pull bracket 20 is pulled to slide the second magnetic member 48 to a side of the rotating shaft 32 away from the first end 21, that is, the second magnetic pole 482 is close to the first magnetic pole 492, so that the second magnetic pole 482 and the first magnetic pole 492 are in a magnetic repulsion state, and then the plug 30 is driven to unfold and rotate relative to the push-pull bracket 20, and finally the push-pull bracket 20 slides to the second position, the magnetic repulsion force of the second magnetic member 48 and the first magnetic member 49 drives the plug 30 to unfold relative to the push-pull bracket 20, and the end of the plug 30 is away from the accommodating space 11. As shown in fig. 26, when the plug 30 needs to be accommodated in the accommodating space 11, the push-pull bracket is pushed to slide from the second position to the first position, so that the abutting edge of the housing abuts against the plug, the abutting edge 133 of the housing 10 pushes the plug 30 to rotate in a closed manner relative to the push-pull bracket 20, and the second magnetic member 48 slides to the side of the rotating shaft 32 close to the first end 21 again, the second north magnetic pole 482 and the first south magnetic pole 491 start magnetic attraction and fit, so that the closing rotation of the plug 30 relative to the push-pull bracket 20 is accelerated, the plug 30 moves towards the accommodating space 11, and a suction feeling exists, so that the plug 30 is quickly reset to a closed state relative to the push-pull bracket 20.

It is understood that the positions of the first south magnetic pole 491 and the first north magnetic pole 492 can be reversed, and the positions of the second south magnetic pole 481 and the second north magnetic pole 482 can be reversed, so that the magnetic force of the first magnetic member 49 and the second magnetic member 48 can be matched to drive the pin 30 to rotate relative to the push-pull bracket 20.

It is understood that the second magnetic member 48 may be a magnetic member having only one magnetic pole, such that the second magnetic member 48 is engaged with the two magnetic poles of the first magnetic member 49, respectively, to drive the pin 30 to rotate relative to the push-pull bracket 20.

An eighth embodiment is provided, and referring to fig. 27 and 28, the same as the first embodiment except that the plug 30 is opened or closed in a sliding manner relative to the push-pull bracket 20, and the power assembly 40 is used for driving the plug 30 to slide relative to the push-pull bracket 20. Specifically, the push-pull bracket 20 is provided with a sliding groove 239 extending perpendicular to the first surface 23, and the pins 20 are slidably fitted into the sliding groove 239. The chute 239 has a telescoping opening 238 in the first surface 23. The power assembly 40 is accommodated between the bottom of the sliding groove 239 and the pins 20. When the push-pull bracket 20 slides to the second position, the telescopic opening 238 of the sliding groove 239 is opposite to the through hole 12, so that the plug 30 is driven by the power assembly 40 to slide and unfold relative to the push-pull bracket 20, and the end of the plug 30 extends out of the telescopic opening 238 and the through hole 12 to be away from the accommodating space 11. When the plug pins 30 need to be accommodated in the accommodating space 11, the plug pins 30 are pushed back to the sliding grooves 239 by applying a pressing force to the plug pins 30, and the push-pull bracket 20 is pushed to slide towards the first position, so that the plug pins 30 are finally accommodated in the accommodating space 11.

Optionally, the power assembly 40 is provided with a spring 47, one end of the spring 47 is fixedly connected with the plug 30, the other end of the spring 47 is abutted against the push-pull bracket 20, and the spring 47 is used for driving the plug 30 to extend relative to the push-pull bracket. When the push-pull bracket 20 slides to the first position and the plug pin 30 is in the closed state relative to the push-pull bracket 20, the plug pin 30 slides along the sliding slot 239 to the state of being accommodated in the sliding slot 239, and the spring 47 is in the elastic compression state, at this time, the plug pin 30 is accommodated in the accommodating space 11. When the push-pull bracket 239 slides to the second position, the pin 30 is no longer limited by the sliding of the housing 10, and the elastic potential energy of the spring 47 is released, so that the pin 30 slides along the sliding slot 239 to a state where the end portion of the pin extends out of the through hole 12, and finally the pin 30 slides to a state where the pin is stably connected with the push-pull bracket 20, so that the pin 30 is conveniently inserted into the power socket.

Of course, in other embodiments, the user may manually drive the prong 30 to slide relative to the push-pull bracket 20, and to avoid the user from contacting the pin leg 32 of the prong 30, a manual driving structure may be provided on the second side 25 of the push-pull bracket 20, and the prong 30 may be driven to slide relative to the push-pull bracket 20 by the manual driving structure.

It can be understood that when the push-pull bracket 20 slides relative to the housing 10, a transmission mechanism may also be used to transmit a sliding moment of the housing 10 to the plug pins 30, so that the plug pins 30 slide and contract relative to the push-pull bracket 20, and thus the plug pins 30 and the push-pull bracket 20 are synchronously linked, so as to ensure that when the push-pull bracket 20 slides to the first position, the plug pins 30 slide to a fully closed state retracted relative to the push-pull bracket 20, and the plug pins 30 are fully accommodated in the accommodating spaces 11, and when the push-pull bracket 20 slides to the second position, the plug pins 30 slide to an extended state relative to the push-pull bracket 20, and the end portions of the plug pins 30 far from the push-pull bracket 20 extend out of the accommodating spaces 11.

In the embodiment of the present application, the movement manner of the insertion pin 30 to open or close with respect to the housing 10 is not limited, and in addition to the insertion pin 30 in the above-described embodiment to open or close rotationally with respect to the housing 10, the insertion pin 30 may also open or close rotationally with respect to the push-pull bracket 20. The power source for the motion of the plug 30 relative to the push-pull bracket 20 is not limited, and the plug 30 may be driven by a user manually, or by a driving mechanism, or by a power source, or may be driven by a combination of a user manually and a power mechanism to move the plug 30 relative to the push-pull bracket 20.

Referring to fig. 29 and 30, a ninth embodiment is provided, which is substantially the same as the first embodiment, except that when the pin 30 is misaligned with the through hole 12, the power element 40 stops providing the rotational torque to the pin 30, and when the pin 30 moves to a position corresponding to the through hole 12, the power element 40 starts providing the rotational torque to the pin 30 and allows the pin 30 to be unscrewed from the through hole 12, so as to prevent the pin 30 from continuously acting on the housing 10 and reduce the strain level of the housing 10. For example, the power assembly 40 is provided with a first magnet 401 fixed on the inner wall of the housing 10 and a second magnet 402 fixed on the pin 30, when the pin 30 moves to a position corresponding to the through hole 12, the first magnet 401 and the second magnet 402 are close to each other, and the first magnet 401 and the second magnet 402 are magnetically attracted or magnetically attracted and repelled with each other, so as to drive the pin 30 to rotate relative to the housing 10, thereby enabling the pin 30 to be screwed out through the through hole 12. Specifically, a first magnet 401 is fixed to the housing 10 adjacent to the through hole 12, and a second magnet 402 is fixed to the pin 30 at a position offset from the axial center of the rotating shaft 31.

A tenth embodiment is provided, and referring to fig. 31, substantially the same as the first embodiment except that the power assembly 40 is provided with a kinetic energy storage member 403 and a transmission assembly 404. The kinetic energy storage member 403 is disposed on the inner wall of the housing 10, and the transmission member 403 is connected to the pin 30. When the pin 30 moves to a position corresponding to the through hole 12, the driving element 404 is connected to the kinetic energy storage element 403, and the through hole 12 allows the kinetic energy storage element 403 to release kinetic energy to the driving element 404, so that the pin 30 is driven by the driving element to rotate, and the pin 30 is screwed out of the through hole 12. The kinetic energy storage member 403 may be a spring, and the transmission member 404 may be a rack and a gear engaged with each other, by providing a button on the housing 10, the button controls the spring to release kinetic energy to the rack and drive the gear to rotate, and finally the gear drives the pin 30 to rotate.

Alternatively, the keys may be provided on the first side surface 15, or on the first end surface 16 or the second end surface 17.

Of course, the button can be replaced by a button key, and the rotation torque of the button key can also be used to control whether the kinetic energy storage part 403 releases the kinetic energy to the transmission component 404, so as to drive the plug 30 to move relative to the push-pull bracket 20.

Further, referring to fig. 32, 33 and 34, the inner surface of the housing 30 is provided with a limiting protrusion 112, the outer surface of the push-pull bracket 20 is provided with a limiting sliding groove 28 slidably engaged with the limiting protrusion 112, the extending direction of the limiting sliding groove 28 is parallel to the sliding direction of the push-pull bracket 20, and two ends of the limiting sliding groove 28 are disposed in a sealing manner, so that the push-pull bracket 20 is limited in sliding relative to the housing 10. When the push-pull bracket 20 drives the plug pin 30 to be screwed out from the through hole 12, the limiting protrusion 112 abuts against one end of the limiting sliding groove 28 close to the second end surface 17 to limit the push-pull bracket 20 to continue sliding towards the second end 17, and after the push-pull bracket 20 drives the plug pin 30 to be accommodated in the housing 10, the limiting protrusion 112 abuts against one end of the limiting sliding groove 28 close to the first end surface 16 to limit the push-pull bracket 20 to further slide towards the first end surface 16.

For the convenience of describing the engaging process of the position-limiting protrusion 112 and the position-limiting sliding groove 28 in detail, the first embodiment is illustrated, and in other embodiments, the engaging relationship of the position-limiting protrusion 112 and the position-limiting sliding groove 28 can refer to the first embodiment.

In the first embodiment, the push-pull bracket 20 is provided with a limit chute 28 on both the first surface 23 and the second surface 24. The housing 10 is provided with a stop protrusion 112 on both the inner surface adjacent the front face 13 and the inner surface adjacent the back face 14. The limit protrusion 112 is slidably engaged with the limit sliding groove 28 during the sliding engagement of the push-pull bracket 20 with the housing 10. The side of the stop lug 112 facing the end plate 16 is provided with a first side wall 113 which is perpendicular to the front face 13 or the rear face 14. The side of the stop lug 112 remote from the end plate 16 is provided with a second side wall 114 which is inclined relative to the first side wall 113. The limiting protrusion 112 is disposed in the accommodating space 11 near the through hole 12 and located on a side of the through hole 12 away from the opening 111 to limit the sliding of the push-pull bracket 20 toward the direction of the extending opening 111 after the plug 30 is screwed out from the through hole 12. The two opposite closed ends of the limiting chute 28 are provided with limiting side walls 281 which are vertical to the first surface 23 or the second surface 24. When the first sidewall 113 abuts against the limiting sidewall 281, the push-pull bracket 20 cannot slide in the direction of the separation opening 111 relative to the housing 10, so as to ensure the safety of the push-pull bracket 20 and the housing 10. In the process of assembling the push-pull bracket 20 and the housing 10, in order to facilitate the push-pull bracket 20 to be inserted into the accommodating space 11 from the opening 111, a leading-in chamfer 211 is arranged at an included angle between the end surface of the first end 21 and the first surface 23 and the second surface 24, and the second side wall 114 is matched with the leading-in chamfer 211, so that the resistance of the limiting protrusion 112 to the insertion and sliding of the push-pull bracket 20 can be reduced, and the push-pull bracket 20 can be conveniently inserted into the accommodating space 11, and the limiting protrusion 112 can slide into the limiting sliding groove 28 from the front surface 23.

Optionally, the first surface 23 and the second surface 24 are both provided with two spacing sliding grooves 28 arranged at intervals. Two spacing protrusions 112 are disposed on the inner surface of the housing 10 adjacent to the front surface 13 and the inner surface adjacent to the back surface 14.

Alternatively, the limiting protrusion 112 may be made of plastic, rubber, or silicone with elastic deformation performance. The position-limiting protrusion 112 may also be a resilient plate having elastic deformation properties.

It is understood that in other embodiments, the limiting sliding groove 28 may be disposed on the inner surface of the housing 10, and the limiting protrusion 112 may be disposed on the outer surface of the push-pull bracket 20. The stop protrusion 112 may also be an inner wall disposed on the inner surface of the housing 10 adjacent to the side surface 15, and the stop runner 28 opens at the second side surface 25.

Further, referring to fig. 35 and fig. 36, the power adapter 100 further includes a circuit board assembly 50 fixed in the accommodating space 11, and the circuit board assembly 50 is electrically connected to the pins 30.

The circuit board assembly 50 is fixed relative to the housing 10, that is, the circuit board assembly 50 and the pins 30 are movably engaged with each other, and in order to ensure stable conduction between the circuit board assembly 50 and the pins 30, a conductive structure is required to be arranged between the circuit board assembly 50 and the pins 30. To illustrate the connection relationship between the circuit board assembly 50 and the pins 30 in detail, the first embodiment is illustrated, and in other embodiments, the connection relationship between the circuit board assembly 50 and the pins 30 can refer to the first embodiment.

In the first embodiment, the accommodating space 11 accommodates the circuit board assembly 50 adjacent to the first end face. The circuit board assembly 50 is remote from the opening 111. During the process of installing the circuit board assembly 50 into the accommodating space 11, the circuit board assembly 50 may be inserted into the accommodating space 11 through the opening 111 and finally inserted to be adjacent to the first end face 16. The circuit board assembly 50 is fixedly connected to the housing 10, or may be fixedly connected to the housing 10 through a bracket fixed to the accommodating space 11. When the circuit board assembly 50 is electrically connected to the pins 30, so that the pins 30 are electrically connected to an external power source, the circuit board assembly 50 can be connected to an external current and process the external current, so that the external current forms a current receivable by the electronic device.

Specifically, the thickness of the circuit board assembly 50 is equal to the distance from the position of the inner surface of the housing 10 adjacent to the front surface 13 to the position of the inner surface adjacent to the back surface 14, so that after the circuit board assembly 50 is accommodated in the accommodating space 11, the internal structure of the housing 10 is compact, and the power adapter 100 is slim and portable.

More specifically, the first end face 16 is provided with a connector interface 161, and the circuit board assembly 50 is provided with an electrical connector 51 that mates with the connector interface 161. The electrical connector 51 is a USB (Universal Serial Bus) connector. The electrical connector 51 is electrically connected to the USB cable via the interface of the connector 161, so that the USB cable connectable to the electronic device conducts the current processed by the circuit board assembly 50 to the electronic device, so that the electronic device can obtain the current via the power adapter 100. The connector interface 161 is provided with the power adapter 100 so that the housing 10 is detachably connected to the USB cable, facilitating the carrying of the power adapter 100.

Referring to fig. 36, 37 and 38, the power adapter 100 further includes a conductive elastic piece 60 and a conductive cable 70, the conductive elastic piece 60 is fixed to the push-pull bracket 20, one end of the conductive elastic piece 60 elastically abuts against the plug pin 30, the other end extends toward the circuit board assembly 50, one end of the conductive cable 70 is electrically connected to the end of the conductive elastic piece 60 extending toward the circuit board assembly 50, the other end is electrically connected to the circuit board assembly 50, and the conductive cable 70 can be bent during the process of the push-pull bracket 20 approaching the circuit board assembly 50.

In this embodiment, the power adapter 100 includes two conductive elastic pieces 60, and the two conductive elastic pieces 60 are electrically connected to the two pin columns 32, respectively. The pin column 32 is provided with a conductive contact end 322 passing through the arc end surface 332, when the pin 30 is screwed out of the receiving slot 210, the conductive contact end 322 elastically abuts against the conductive elastic sheet 60, and when the pin 30 is completely screwed into the receiving slot 210, the conductive contact end 322 is separated from the conductive elastic sheet 60.

Specifically, the conductive elastic piece 60 includes a fixed end 61 and a bent end 62. The securing end 61 is clamped to the end of the bearing boss and the inner wall bracket of the second housing 27. The bent end 62 is opposite the pin leg 32 of the pin 30. The bent end 62 is bent along a curve. The bent end 62 has elastic deformation properties. When the plug 30 is in a state of being screwed out of the receiving slot 210, the conductive contact end 322 rotates to contact with the bent end 62, so that the bent end 62 deforms, the bent end 62 applies an elastic contact force to the conductive contact end 322, and the plug 32 is in closer contact with the conductive elastic sheet 60, so that the plug 32 has a damping force in the overturning process, i.e. the plug 30 has a damping force in the overturning process relative to the push-pull bracket 20, so as to reduce the overturning impact acting force of the plug 30 on the push-pull bracket 20. When the pin 30 is completely screwed into the receiving slot 210, the conductive contact end 322 is rotated to be separated from the bent end 62, and the bent end 62 returns to a natural stretching state.

More specifically, the first housing 26 is further provided with a spring clip groove 262 at one side of the bearing boss, the conductive spring 60 is provided with a conductive support leg 63 clamped in the spring clip groove 262, one end of the conductive support leg 63 extends toward the circuit board assembly 50, and one end of the conductive support leg 63 is electrically connected to the conductive cable 70. The elastic sheet clamping groove 262 stabilizes the conducting support leg 63, so that the conducting support leg 63 can still keep effective contact with the conductive cable 70 after the pin 30 is overturned for a plurality of times relative to the push-pull bracket 20, the stability of the conductive elastic sheet 60 is improved, the performance of effective conduction with the conductive cable 70 is improved, and the service life of the power adapter 100 is prolonged. The conductive cable 70 can be bent so that the push-pull bracket 20 can slide relative to the housing 10, thereby ensuring the sliding smoothness of the push-pull bracket 20.

Alternatively, the conduction leg 63 is provided with a through groove through which the end of the rotation shaft 31 passes so that the end of the rotation shaft 31 receives the driving force of the power assembly 40.

Referring to fig. 39, 40 and 41, in the first embodiment, the push-pull bracket 20 is partially exposed out of the housing 10, and the portion of the push-pull bracket 20 exposed out of the housing 10 is used for receiving a push-pull driving force, so that the push-pull bracket 20 slides along the accommodating space 11. The portion of the push-pull bracket 20 exposed to the housing 10 may receive an external driving force. For example, the portion of the push-pull bracket 20 exposed to the housing 10 receives a user's push-pull force. When the user manually pushes the portion of the push-pull bracket 20 exposed out of the housing 10 to slide toward the first end surface 16, that is, the push-pull bracket 20 slides from the second position to the first position, so that the push-pull bracket 20 drives the plug pins 30 to move into the accommodating space 11, and the plug pins 30 are closed relative to the push-pull bracket 20 under the supporting action of the housing 10, and finally the plug pins 30 are screwed into the accommodating space 11. When the user manually pulls the portion of the push-pull bracket 20 exposed out of the housing 10 to slide away from the first end surface 16, that is, the push-pull bracket 20 slides from the second position to the first position, so that the push-pull bracket 20 drives the plug 30 to move to the area corresponding to the through hole 12, the end of the plug 30 is rotated out of the accommodating space 11 under the driving force of the power assembly 40 and extends out of the housing 10.

Specifically, the housing 10 is provided with a push-pull groove 19, the push-pull bracket 20 is provided with a push-pull key 211 slidably engaged with the push-pull groove 19, and the push-pull key 211 is exposed out of the housing 10 through the push-pull groove 19. The housing 10 is provided with push-pull grooves 19 on both first sides 15. The push-pull bracket 20 is provided with two push-pull keys 211, the two push-pull keys 211 are respectively arranged on the two second side surfaces 25 of the push-pull bracket 20, and the two push-pull keys 211 are respectively arranged on the two sides of the push-pull bracket 20 in the width direction, so as to avoid the increase of the whole thickness of the power adapter 100.

Optionally, the push-pull key 211 includes a push-pull plate 212 and at least two posts 213 disposed inside the push-pull plate 212. The side of the first casing 26 is provided with at least one insertion hole 262, the side of the second casing 27 is provided with at least one insertion hole 262, and at least two insertion posts 213 of the push-pull key 211 are respectively in insertion fit with the at least two insertion holes 262 on the same side of the push-pull bracket 20, so that the push-pull key 211 is stable with the first casing 26 and the second casing 27.

Optionally, a surface of the push-pull plate 212 facing away from the plug column 213 is provided with a corrugated surface, so that the friction force of the push-pull plate 212 contacting with the finger of the user is increased, and the user can apply the push-pull force to the push-pull key 211 conveniently.

Of course, in other embodiments, the push-pull key 211 may be integrally formed with the first housing 26 or the second housing 27 to increase the stability of the push-pull key 211 with the first housing 26 or the second housing 27.

More specifically, the push-pull groove 19 is disposed on the first side surface 15 adjacent to the second end surface 17, and the push-pull groove 19 is in communication with the opening 111. The push-pull key 211 is provided at the second end 22 of the push-pull bracket 20. When the push-pull bracket 20 slides to the first position, the plug 30 is screwed into the receiving space 11, the second end 22 is engaged with the opening 111, and the push-pull key 211 slides into the push-pull groove 19 to plug the push-pull groove 19. When the push-pull bracket 20 is slid to the second position and the plug 30 is away from the accommodating space 11, the second end 22 is extended relative to the housing 10, and the push-pull key 211 slides out of the push-pull groove 19.

In the eleventh embodiment, referring to fig. 42, the push-pull groove 19 is spaced apart from the first end surface 16 and the second end surface 17. The two ends of the push-pull groove 19 are closed. The push-pull key 211 slides back and forth at both ends of the push-pull slot 19 to move the push bracket 20 back and forth between the first end surface 16 and the second end 17. When the push-pull bracket 20 slides to the first position, the push-pull key 211 slides to the end of the push-pull groove 19 near the first end surface 16, and the push-pull bracket 20 drives the plug pins 30 to rotate into the accommodating space 11. When the push-pull bracket 20 slides to the second position, the push-pull key 211 slides to the end of the push-pull slot 19 close to the second end surface 17, and the push-pull bracket 20 drives the plug pins 30 to move away from the accommodating space 11.

In a twelfth embodiment, referring to fig. 43 and 44, substantially the same as the first embodiment, except that the front plate 13 and the back plate 14 are provided with two push-pull grooves 19. The positive plate 13 is provided with two push-pull grooves 19, the two push-pull grooves 19 of the positive plate 13 are respectively located at two sides of the through hole 12, the outer surface of the first shell 26 is provided with two push-pull keys 211, and the outer surface of the second shell 27 is provided with two push-pull pieces 211, so that a user can pinch the part in the thickness direction of the push support, and the push support 20 is driven to slide relative to the shell 10.

Further, referring to fig. 45 and 46, the power adapter 100 further includes a damping mechanism 80 disposed between the housing 10 and the push-pull bracket 20, wherein the damping mechanism 80 is configured to provide a damping force for the sliding of the push-pull bracket 20 relative to the housing 10.

In the present embodiment, the damping mechanism 80 is disposed in the accommodating space 11. The damping mechanism 80 is located at a portion where the inner surface of the housing 10 is engaged with the outer surface of the push-pull bracket 20. The damping force of the damping mechanism 80 can make the sliding process of the push-pull support 20 relative to the housing 10 have a stagnation feeling, and prevent the push-pull support 20 from sliding too smoothly relative to the housing 10, thereby causing the mutual collision between the push-pull support 20 and the housing 10.

In the first embodiment, the damping mechanism 80 includes a first damping protrusion 81 and a second damping protrusion 82 disposed on the inner surface of the housing 10, and a sliding protrusion 83 disposed on the outer surface of the push-pull bracket 20, the first damping protrusion 81 and the second damping protrusion 82 are disposed at an interval in the sliding direction of the push-pull bracket 20, and the sliding protrusion 83 is in interference fit with the first damping protrusion 81, so that the end of the pin 30 driven by the push-pull bracket 20 is prevented from being damped when the pin is about to finally get away from the accommodating space 11, that is, the push-pull bracket 20 is about to slide to the second position. The sliding protrusion 83 and the second damping protrusion 82 are in abutting fit, so that the damping force is applied when the push-pull bracket 20 drives the end of the plug 30 to just start to be away from the accommodating space 11, that is, when the push-pull bracket 20 just starts to slide from the first position to the second position, the damping force is applied.

Specifically, the first and second damping

protrusions

81 and 82 are each disposed on the inner surface of the housing 20 adjacent to the first side 15. The first damping projection 81 is located closer to the first end surface 16 than the second damping projection 82. The second damping projection 82 is close to the opening 111 with respect to the first damping projection 81. The sliding protrusion 83 is disposed on a side of the first housing 26. The side of the first casing 26 is provided with a damping sliding groove 263, and the sliding protrusion 83 is disposed in the damping sliding groove 263. The first and second damping

projections

81 and 82 are slidably fitted to the damping slide grooves 263. The damping chute 263 has a damping opening at the first end 21 and is closed at a location remote from the first end 21. The sliding protrusion 83 is disposed on the damping sliding groove 263 near the damping opening. Of course, in other embodiments, the damping chute 263 may be disposed on the side of the second casing 27, and the sliding protrusion 83 may be disposed on the second casing 27. The damping sliding groove 263 can be disposed on one half of the side of the first casing 26, the other half of the side of the second casing 27, and the sliding protrusion 83 is disposed on one half of the first casing 26 and the other half of the side of the second casing 27.

More specifically, the first damping projection 81 has a first inclined surface 811 and a second inclined surface 812 inclined with respect to the first inclined surface 811, and the second damping projection 82 has a third inclined surface 821 and a fourth inclined surface 822 inclined with respect to the third inclined surface 821. When the push-pull bracket 20 rotates the plug 30 from the closed state to the final unscrewed state, the sliding protrusion 83 is in interference fit with the first inclined surface 811, the second inclined surface 812, the third inclined surface 821 and the fourth inclined surface 822 in sequence.

The first inclined surface 811 is parallel to the fourth inclined surface 822. The second inclined surface 812 is parallel to the third inclined surface 821. The first inclined surface 811, the second inclined surface 812, the third inclined surface 821 and the fourth inclined surface 822 may form a slope surface with the inner surface of the side panel 15 as a reference surface. The slope of the first inclined surface 811 is greater than the slope of the second inclined surface 812.

The sliding protrusion 83 has a fifth inclined surface 831 substantially parallel to the first inclined surface 811 and a sixth inclined surface 832 substantially parallel to the second inclined surface 812. When the push-pull bracket 20 is ready to slide from the first position to the second position, the plug pin 30 is accommodated in the accommodating space 11, the first inclined surface 811 abuts against and cooperates with the fifth inclined surface 831, at this time, the push-pull bracket 20 is pushed to drive the plug pin 30 to start to move away from the accommodating space 11, a large blocking feeling exists, and a large pushing force needs to be applied to the push-pull bracket 20 to drive the push-pull bracket 20 to slide, so that the push-pull bracket 20 is prevented from sliding relative to the housing 10 under the action of gravity. When the fifth inclined surface 831 slides over the first inclined surface 811 and the sixth inclined surface 832 is in sliding engagement with the second inclined surface 812, the sliding damping force applied to the push-pull bracket 20 is instantaneously reduced, and the push-pull bracket 20 slides toward the second position with respect to the housing 10, thereby providing a boosting feeling. When the fifth inclined surface 831 slides to abut against and cooperate with the third inclined surface 821, the push-pull bracket 20 is about to slide to the second position, the prong 30 is in an expanded state relative to the push-pull bracket 20, and the end of the prong 30 is about to move to a posture that is finally far away from the accommodating space 11, at this time, the push-pull bracket 20 is subjected to a damping action force again, the damping action force is small, the push-pull bracket 20 slides relative to the push-pull bracket 20 with a certain retardation feeling, so as to reduce the rotating speed of the prong 30 that is finally far away from the accommodating space 11, and avoid the collision between the prong 30 and the push-pull bracket 20 and the collision between the push-pull bracket 20 and the housing 10, thereby ensuring the safety of the power adapter 100. When the fifth inclined surface 831 slides over the third inclined surface 821 and the sixth inclined surface 832 is in sliding fit with the fourth inclined surface 822, the push-pull bracket 20 slides to the second position, the end of the pin 30 moves rapidly to a state finally far away from the accommodating space 11, the push-pull bracket 20 is again assisted by the aid of the aid and is kept in a positioning state, so that the sixth inclined surface 832 is subjected to a large resistance by the aid of the fourth inclined surface 822, the push-pull bracket 20 is limited to automatically retract, the end of the pin 30 is kept in a state finally far away from the accommodating space, and the end of the pin 30 is conveniently and effectively plugged with an external power socket.

protrusions

81 and 82 may also be disposed on the inner surface of the housing 10 adjacent to the front surface 13 or adjacent to the back surface 14. The sliding protrusion 83 may be provided on the outer surface of the first housing 26 or the outer surface of the second housing 27.

Referring to fig. 47, a thirteenth embodiment is provided, which is substantially the same as the first embodiment, except that the damping mechanism 80 includes a first damping member 84 fixed on the inner surface of the housing 10 and a second damping member 85 fixed on the outer surface of the push-pull bracket 20, and the first damping member 84 and the second damping member 85 are magnetically engaged to make the push-pull bracket 20 under the action of magnetic resistance during the sliding process relative to the housing 10.

The first damping member 84 is fixed to the inside of the side plate 15. The second damping member 85 is fixed to a side of the first housing 26. The number of the first damping members 84 is two. The two first damping members 84 are respectively disposed at intervals in the sliding direction of the push-pull bracket 20. The second damping member 85 is provided at the first end 21 of the push-pull bracket 20. When the second damping member 85 is magnetically engaged with the first damping member 84 sliding to be close to the end plate 16 (see fig. 1), the first damping member 84 exerts a magnetic attractive force or a magnetic repulsive force to the second damping member 85 to prevent the push-pull bracket 20 from sliding relative to the housing 10, so that the push-pull bracket 20 is maintained in a state of being contracted with the housing 10, i.e., the pin 30 is maintained in a state of being closed relative to the push-pull bracket 20. When the second damping member 85 slides to magnetically engage with the first damping member 84 away from the end plate 16, the first damping member 84 exerts a magnetic attraction force or a magnetic repulsion force on the second damping member 85 to prevent the push-pull bracket 20 from sliding relative to the housing 10, so that the push-pull bracket 20 is maintained in a state of being extended from the housing 10, i.e., the pin 30 is maintained in a state of having its end away from the accommodating space 11.

Alternatively, the first damping member 84 is a magnet and the second damping member 85 is a magnet.

Alternatively, the first damping member 84 is a magnet, and the second damping member 85 is a ferrous member.

The damping holder 87 is disposed at the first end 21 of the push-pull bracket 20. The damping elastic member 86 is provided with a slot, when the damping abutting member 87 slides to be matched with the slot, the damping elastic member 86 applies an elastic clamping acting force to the damping abutting member 87, so that the push-pull bracket 20 slides relative to the outer shell 10 with a damping acting force, and the push-pull bracket 20 can keep a relative static state with the outer shell 10 under the condition that the driving acting force to the push-pull bracket 20 is cancelled. When the damping support member 87 slides to the position close to the first end surface 16, the damping elastic member 86 exerts an elastic holding force on the damping support member 87 to prevent the push-pull bracket 20 from sliding relative to the housing 10, so that the push-pull bracket 20 is kept in a state of being contracted with respect to the housing 10, i.e. the pin 30 is kept in a closed state with respect to the push-pull bracket 20. When the damping support member 87 slides to the position far away from the damping elastic member 86 of the first end surface 16 to be clamped and matched, the damping elastic member 86 exerts an elastic clamping force on the damping support member 87 to prevent the push-pull bracket 20 from sliding relative to the housing 10, so that the push-pull bracket 20 keeps the end part far away from the accommodating space 11, i.e. the pin 30 keeps the state of being unfolded relative to the push-pull bracket 20.

It is to be understood that the power adapter 100 of the present application is not limited to the above-mentioned power adapter that uses the push-pull key 19 (see fig. 20) to receive the push-pull force of the user to drive the push-pull bracket 20 to slide, for example, the power adapter 100 may also be provided with a driving mechanism inside the housing 10, and the driving mechanism may be used to drive the push-pull bracket 20 to slide.

When the push-pull bracket 20 contracts relative to the housing 10, the elastic driving member 90 compresses and stores kinetic energy, and the pin 30 starts to be screwed into the accommodating space 11. When the elastic driving member 90 releases kinetic energy to the push-pull bracket 20, the elastic driving member 90 drives the push-pull bracket 20 to extend and slide relative to the housing 10 and drives the plug 30 to move to the region corresponding to the through hole 12, and the plug 30 can be screwed out of the housing 10 under the action of the power assembly 40.
