[0064] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments.

[0065] Please refer to Figure 1 , Figure 2 and Figure 3The power adapter 100 includes a support 10, a pin 20 rotatably connected to the support 10, and a moving part 30 movably connected to the support 10. The pin 20 can move with the moving part 30 relative to the support 10 and can be reversibly extended or retracted from the support 10. It can be understood that the power adapter 100 is inserted into a power socket by the pin 20, so that the power adapter 100 can obtain electric energy, thereby facilitating the transmission of electric energy to electronic devices such as mobile phones, smart watches, notebook computers, tablet computers, and smart earphones. The pin 20 of the power adapter 100 can be a pin of various standards such as the national standard, the European standard, the American standard, the British standard, the Australian standard, the Japanese standard, and the Korean standard.

[0066] The moving part 30 is arranged on the support 10, and the pin 20 is rotatably connected to the support 10. Moving the moving part 30 allows the pin 20 to move with the moving part 30 and reversibly extend or retract from the support 10, i.e., without contacting the pin 20, the pin 20 can be extended or retracted, so that the power adapter 100 is convenient, labor-saving, and safe to use.

[0067] In this embodiment, the power adapter 100 further includes a shell 90, the support 10 is fixed in the shell 90, the shell 90 stably protects the support 10, and increases the appearance performance of the power adapter 100. The shell 90 is provided with an inner cavity 99 and a through slot 91 communicating with the inner cavity 99. The pin 20 can reversibly extend or retract from the through slot 91 relative to the shell 90. That is, the pin 20 is rotatably connected to the support 10 at a position opposite the through slot 91. The moving part 30 movably connects the support 10 by penetrating the shell 90. The moving part 30 is at least partially exposed from the shell 90, so that the moving part 30 can receive the operating force of a user and move relative to the support 10 and the shell 90.

[0068] The support 10 is accommodated in the inner cavity 99 and is provided with a boss 109 matched with the through slot 91. The boss 109 has an abutting surface 108 away from the inner cavity 99, and the boss 109 is provided with a receiving groove 18 at the abutting surface 108. When the pin 20 extends relative to the support 10 and the shell 90, the end of the pin 20 rotatably connected to the support 10 is located in the receiving groove 18, and the other end is located outside the receiving groove 18. When the pin 20 retracts relative to the support 10 and the shell 90, the pin 20 is completely accommodated in the receiving groove 18, so as to hide and protect the pin 20, reduce the volume of the power adapter 100, and facilitate carrying. When the pin 20 extends relative to the support 10 and the shell 90, the part of the pin 20 protruding from the abutting surface 108 can be inserted into the power socket, the abutting surface 108 abuts against the power socket, and the shell 90 is prevented from contacting the power socket. The shell 90 protects the support 10. The shell 90 can also accommodate a circuit board electrically connected to the pin 20, so as to facilitate the power adapter 100 to receive electric current and process the electric current.

[0069] Optionally, the abutting surface 108 of the boss 109 is flush with the surface of the shell 90 to ensure the appearance flatness of the power adapter 100. The abutting surface 108 and the surface of the shell 90 allow a certain assembly gap. In order to ensure that the abutting surface 108 always contacts the power socket first, the abutting surface 108 is slightly protruding from the outer surface of the shell 90.

[0070] Optionally, the abutting surface 108 of the boss 109 is protruding relative to the surface of the shell 90, that is, the end of the boss 109 is protruding relative to the surface of the shell 90. When the pin 20 is inserted into the power socket, the shell 90 always has a certain gap with the power socket to ensure the safety of the shell 90.

[0071] It can be understood that the power adapter 100 adopts the pin 20 which can be flipped out or retracted. In order to ensure that the pin 20 can be frequently flipped, the structure part bearing and connecting the pin 20 has a high anti-fatigue requirement. The pin 20 needs to obtain electric energy in the state of being inserted into the power socket, so the pin 20 often faces the situation of arc combustion caused by high-voltage circuit short circuit. Therefore, in order to ensure the safety of the power adapter 100, the structure part bearing and connecting the pin 20 has a high requirement of fireproof and anti-combustion. Obviously, in the embodiment of the present application, the bracket 10 bears the pin 20, the bracket 10 isolates the pin 20 from the shell 90, and the bracket 10 has better insulation protection performance, better wear resistance and pressure resistance, and better fireproof and anti-combustion performance, which can ensure the safety of the power adapter 100 and increase the service life of the power adapter 100. Rotatingly connecting the pin 20 to the bracket 10 can avoid the shell 90 being inserted into the power socket, avoid the shell 90 being scratched, avoid the shell 90 being damaged, and ensure the appearance performance of the power adapter 100.

[0072] Specifically, the shell 90 has a first end 92, a second end 93 opposite to the first end 92, and a circumferential side 94 disposed between the first end 92 and the second end 93. The through slot 91 is disposed at the circumferential side 94 adjacent to the first end 92. The shell 90 is provided with an insertion hole 95 at the first end 92, which is in communication with the inner cavity 99 and the through slot 91. The bracket 10 can be inserted into the inner cavity 99 through the insertion hole 95, and the boss 109 is limited by the through slot 91. It can be understood that the inner circumferential wall of the inner cavity 99 and the outer circumferential wall of the bracket 10 are gap-fitted, so that after the bracket 10 is inserted into the inner cavity 99 through the insertion hole 95, it can be stably located in the inner cavity 99. The end of the through slot 91 away from the insertion hole 95 has a blocking wall, which limits the boss 109 and limits the insertion of the bracket 10 into the inner cavity 99 to prevent the bracket 10 from being excessively retracted into the shell 90.

[0073] Optionally, the peripheral side 94 has a front surface 941 and a back surface 942 opposite to the front surface 941, and a side surface 943 connecting the front surface 941 and the back surface 942. The through slot 91 is formed in the front surface 941.

[0074] Please refer to Figure 2 、 Figure 3 and Figure 4 In this embodiment, the bracket 10 has a front surface 11, a back surface 12 opposite to the front surface 11, a first end surface 13 and a second end surface 14 connected to the front surface 11 and the back surface 12 and arranged oppositely, and a first side surface 15 and a second side surface 16 connected to the front surface 11 and the back surface 12 and arranged oppositely. The boss 109 is arranged at the front surface 11 and adjacent to the first end surface 13. The pin 20 extends from the front surface 11 or is retracted in the bracket 10. The first end surface 13 and the second end surface 14 can be respectively located at the front and back ends of the bracket 10, and the first side surface 15 and the second side surface 16 can be located at the left and right sides of the bracket 10. After the bracket 10 is fixed in the inner cavity 99, the first end surface 13 is close to the first end portion 92 of the shell 90, and the second end surface 14 is accommodated in the inner cavity 99.

[0075] In this embodiment, when the pin 20 is in the extended state relative to the bracket 10, the end portion of the pin 20 protrudes relative to the front surface 941. The end portion of the pin 20 is provided with a metal conductor so as to facilitate the conduction between the pin 20 and the power supply electrode in the power supply socket, and the abutting surface 108 abuts against the power supply seat. When the pin 20 is in the retracted state relative to the bracket 10, the pin 20 is accommodated in the accommodation slot 18, so that the whole power supply adapter 100 is in the shape of a rectangular block, thereby facilitating the storage and carrying of the power supply adapter 100, and the pin 20 can be effectively protected by the bracket 10, ensuring safety.

[0076] Specifically, the pin 20 is provided with a rotating shaft 21 and two pin columns 22 fixed on the rotating shaft 21. The length direction of the pin column 22 is perpendicular to the length direction of the rotating shaft 21. The central axis of the pin column 22 intersects with the central axis of the rotating shaft 21. The two pin columns 22 are side by side in the axial direction of the rotating shaft 21. The rotating shaft 21 is always located in the receiving groove 18. The rotating shaft 21 is adjacent to the first end surface 13 away from the receiving groove 18, so that the end of the pin column 22 away from the rotating shaft 21 can be flipped out of the receiving groove 18. When the pin 20 is in the retracted state relative to the support 10, the bottom wall of the receiving groove 18 limits the pin 20 to prevent the pin 20 from being excessively retracted into the support 10. When the pin 20 is in the extended state relative to the support 10, the side wall of the receiving groove 18 adjacent to the rotating shaft 21 limits the pin 20 to prevent the pin 20 from being flipped at too large an angle relative to the support 10, which is not conducive to the pin 20 being plugged into the power socket. The rotating shaft 21 can be provided with an insulator that covers one end of the pin column 22. The rotating shaft 21 separates the two pin columns 22 to prevent short circuiting of the two pin columns 22. The pin column 22 is a metal piece to enable the pin 20 to obtain current.

[0077] The boss 109 is provided with two opposite receiving grooves 18. The rotating shaft 21 passes through the two receiving grooves 18, and the two pin columns 22 can be flipped to extend or retract in the two receiving grooves 18, respectively. The use of the two receiving grooves 18 to receive the two pin columns 22, respectively, increases the stability of the support 10 and effectively isolates the two pin columns 22 to prevent short circuiting of the pin columns 22. It can be understood that the pin column 22 flipped to extend out of the receiving groove 18 means that the pin column 22 rotates relative to the support 10 in a flipping motion and causes the end of the pin column 22 to rotate out of the receiving groove 18 so that the end of the pin column 22 can be plugged into the power socket. The pin column 22 flipped to retract into the receiving groove 18 means that the pin column 22 rotates relative to the support 10 in a flipping motion and causes the pin column 22 to be entirely received in the receiving groove 18 for easy carrying.

[0078] In this embodiment, the support 10 is provided with a receiving cavity 17 for receiving devices such as a circuit board, a power supply chip, and a power supply transformer module. A part of the end of the pin 20 that is rotationally connected to the support 10 is received in the receiving cavity 17, so that the pin 20 can be electrically connected to the devices such as the circuit board, the power supply chip, and the power supply transformer module. Optionally, the support 10 includes a first housing 101 and a second housing 102 that covers the first housing 101. The boss 109 is arranged on the side of the first housing 101 away from the second housing 102, and the rotating shaft 21 is rotationally connected between the first housing 101 and the second housing 102. The front surface 11 is formed on the side of the first housing 101 away from the second housing 102, and the back surface 12 is formed on the side of the second housing 102 away from the first housing 101. The first housing 101 and the second housing 102 clamp the rotating shaft 21, so that the rotating shaft 21 rotates smoothly and stably relative to the support 10.

[0079] Specifically, the bearing boss 103 is formed on the side of the first shell 101 facing the second shell 102 corresponding to the accommodation groove 18, and the bearing protrusion 104 is arranged on the side of the second shell 102 facing the first shell 101 and is matched with the bearing boss 103. The first U-shaped groove 105 is arranged on the bearing boss 103, and the second U-shaped groove 106 is arranged on the bearing protrusion 104. The first U-shaped groove 105 and the second U-shaped groove 106 jointly bear the rotating shaft of the pin 20, so that the pin 20 can be flipped relative to the support 10. The first U-shaped groove 105 is communicated with the accommodation cavity 17 and the accommodation groove 18. Two first U-shaped grooves 105 are arranged on the two side walls of the bearing boss 103, so that the rotating shaft 21 passes through the accommodation groove 18 through the first U-shaped groove 105, and the pin post 22 is fixed to the part of the rotating shaft 21 passing through the accommodation groove 18. Four bearing protrusions 104 are arranged on the second shell 102 corresponding to the four second U-shaped grooves 106, so as to increase the structural stability of the rotating shaft 21 and the support 10, ensure the smooth rotation of the rotating shaft 21 relative to the support 10, and effectively isolate the two pin posts 22.

[0080] In the embodiment, the power adapter 100 further includes two pin springs 60, and the two pin springs 60 are electrically connected with the two pin posts 22 respectively. The pin post 22 is provided with a conductive contact end 23 away from the rotating shaft 21. When the pin 20 is flipped relative to the support 10 to the extending process, the conductive contact end 23 elastically contacts the pin spring 60. When the pin 20 is flipped relative to the support 10 to the retracted state, the conductive contact end 23 is separated from the pin spring 60.

[0081] Specifically, the pin spring 60 includes a fixed end 61 and a curved end 62. The fixed end 61 is clamped to the end of the bearing boss 103 and the inner wall support of the second shell 102. The curved end 62 is opposite to the pin post 22 of the pin 20. The curved end 62 is curved along a curve. The curved end 62 has an elastic deformation performance. When the pin 20 is flipped relative to the support 10 to the extending process, the conductive contact end 23 is rotated to contact the curved end 62, so that the curved end 62 is deformed, the curved end 62 exerts an elastic contact force on the conductive contact end 23, the pin post 22 is more closely contacted with the pin spring 60, and the pin post 22 has a damping force in the flipping process, that is, the pin 20 has a damping force in the flipping process relative to the support 10, so as to reduce the flipping impact force of the pin 20 on the support 10. When the pin 20 is flipped relative to the support 10 to the retracted state, the conductive contact end 23 is rotated to a separated state from the curved end 62, and the curved end 62 returns to a natural relaxed state.

[0082] More specifically, the first housing 101 is further provided with a spring clamping groove 107 on one side of the bearing boss 103, the pin spring 60 is provided with a conducting leg 63 clamped into the spring clamping groove 107, the end of the rotating shaft 21 extends into the spring clamping groove 107 and is in contact with the conducting leg 63, so that the pin column 22 is kept in a conducting state with the conducting leg 63 through the rotating shaft 21. The rotating shaft 21 is provided with shaft conductors in contact with the two pin columns 22 respectively, the ends of the shaft conductors extend into the spring clamping groove 107 and are in contact with the conducting leg 63. The parts of the two shaft conductors of the rotating shaft 21 connected with the pin columns 22 are covered by an insulator to prevent short circuit. The spring clamping groove 107 is stable to the conducting leg 63, so that the pin spring 60 can keep effective contact with the pin 20 after the pin 20 is turned over relative to the support 10 for many times, the stability of the pin spring 60 is increased, the effective conducting performance between the pin spring 60 and the pin 20 is increased, and the service life of the power adapter 100 is increased.

[0083] In the embodiment, please refer to Figure 1 , Figure 2 and Figure 3 , the moving part 30 is movably arranged on the support 10. The moving part 30 can be arranged on the back surface 12, the first side surface 15, the second side surface 16, the first end surface 13 and the second end surface 14. The moving part 30 can move linearly on the support 10, or can rotate on the support 10, or can have a combined motion of linear motion and rotation on the support 10. The moving part 30 can be moved under the manual driving force of a user. The moving part 30 is separated from the receiving groove 18 to avoid the moving part 30 approaching the pin 20, so that the user can control the moving part 30 on the support 10 away from the pin 20, and the pin 20 can be extended or retracted relative to the support 10 to ensure safety.

[0084] In the first embodiment, please refer to Figure 2 , Figure 3 and Figure 5 , the moving part 30 is provided with a button 31. The button 31 is slidably arranged on the support 10 in a pressable manner. The button 31 is located outside the receiving groove 18. The button 31 can be used as a motion switch trigger key for locking or unlocking the pin 20. For example, when the button 31 is not pressed, a part of the button 31 protrudes from the outer surface of the support 10, the pin 20 is in a locked state, the pin 20 remains stationary relative to the support 10, and the pin 20 is limited in a retracted state relative to the support 10. When the button 31 is pressed, the button 31 is retracted relative to the support 10, the pin 20 is in an unlocked state, and the pin 20 is triggered to receive a driving force to realize the turning motion of the pin 20 relative to the support 10. The pin 20 can receive the driving force from the driving member 51 in the receiving cavity 17, and the driving member 51 can be any device capable of outputting a driving force, such as a spring receiving an elastic force, a magnet receiving a magnetic force, or a piston receiving a gas pressure.

[0085] It can be understood that when the prong 20 is flipped out relative to the bracket 10, an action force is applied to the prong 20 so that the prong 20 is flipped back and retracted, and the flipping torque of the prong 20 can be returned to the driving member 51 to make the driving member 51 store energy, and finally the key 31 is reset to the state of protruding relative to the bracket 10, and the prong 20 and the transmission part 40 are locked again.

[0086] In the embodiment, the key 31 is arranged on the first side surface 15 or the second side surface 16 of the bracket 10. The straight sliding direction of the key 31 is substantially perpendicular to the first side surface 15 or the second side surface 16. Specifically, the key 31 is taken as an example of passing through the first side surface 15 of the bracket 10. The bracket 10 is provided with a key hole 151 on the first side surface 15. The key hole 151 is formed by splicing a first half hole arranged on the edge of the first shell 101 and a second half hole arranged on the edge of the second shell 102. The key 31 is assembled in the key hole 151. When the key 31 is pressed, the key 31 can be retracted in the key hole 151. When the key 31 is not pressed, the end of the key 31 can protrude out of the key hole 151 to present the state that the key 31 is partially protruded relative to the bracket 10, so as to facilitate the key 31 to be pressed. The shell 90 is provided with a key outer hole 944 corresponding to the side surface 943 for the key 31 to pass through, so that the key 31 is partially protruded relative to the shell 90, and the key 31 is facilitated to receive the pressing action force.

[0087] In the embodiment, the key 31 includes a key base 311 and a key cap 312 arranged on the key base 311. The key base 311 is in sliding cooperation with the key hole 151. The key cap 312 is used to receive the pressing action force. After the key cap 312 receives the pressing action force, the key cap 312 is located in the key hole 151, and the key base 311 can trigger the prong 20 to receive the driving torque of the driving member 51, so that the prong 20 is in the unlocked state and starts to rotate. When the key cap 312 does not receive the pressing action force, the key base 311 can reset the key cap 312 to the state of protruding relative to the bracket 10, and the key base 311 can lock the rotating shaft 21 of the prong 20 again to limit the movement of the transmission part 40 and the rotating shaft 21 of the prong 20.

[0088] As an implementation mode, please refer to Figure 5 , Figure 6 and Figure 7The outer circumferential side wall of the key base 311 is provided with a guide protrusion 313, and the inner circumferential side wall of the key hole 151 is provided with a guide groove matched with the guide protrusion 313. The guide protrusion 313 and the guide groove are matched in sliding, so that the key base 311 and the key hole 151 can slide smoothly, and the controllability of the key 31 being pressed and slid is improved. Of course, in other embodiments, the outer circumferential side wall of the key base 311 can be provided with a guide groove, and the inner circumferential side wall of the key hole 151 can be provided with a guide protrusion 313 matched with the guide groove in sliding. The guide protrusion 313 and the guide groove are matched in sliding, so that the key base 311 and the key hole 151 can slide smoothly.

[0089] Optionally, the key base 311 is in a rectangular block shape, and the key base 311 is provided with two guide protrusions 313 on opposite sides, respectively.

[0090] Optionally, the key cap 312 is in a circular column shape, so as to facilitate the key 31 being pressed and improve the pressing comfort of the key 31.

[0091] Optionally, the straight-line slidable direction of the key 31 is parallel to the axial direction of the rotating shaft 21, so as to facilitate the key 31 being non-rotatable relative to the support 10, and thus the rotation of the rotating shaft 21 can be limited.

[0092] Of course, in other embodiments, the key hole 151 can also be arranged on the back surface 12, or arranged on the first end surface 13, or arranged on the second end surface 14, that is, the key 31 can be pressed on the back surface 12 of the support 10, or pressed on the first end surface 13, or pressed on the second end surface 14.

[0093] In the embodiment, the power adapter 100 further includes a driving assembly 50 connected with the key 31 and the pin 20. When the key 31 is in a pressed state, the key 31 releases a driving torque of the driving assembly 50 to the rotating shaft 21 of the pin 20; when the key 31 is in an unpressed state, the key 31 limits the driving assembly 50 from releasing the driving torque to the rotating shaft 21 of the pin 20. The driving assembly 50 can release a rotating torque to the rotating shaft 21, or release a straight-line sliding torque to the rotating shaft 21, or release a composite torque of the rotating torque and the straight-line torque to the rotating shaft 21. It can be understood that when the key 31 is in the pressed state, the key 31 is unlocked with a part of the driving assembly 50, so as to release the limited state of the driving assembly 50. When the key 31 is in the unpressed state, the key 31 is locked with the part of the driving assembly 50, so as to keep the limited state of the driving assembly 50.

[0094] Specifically, the driving assembly 50 comprises a limiting piece 52 and a driving piece 51. The limiting piece 52 is connected to the rotating shaft 21 and the driving piece 51. When the button 31 is in an unpressed state, the limiting piece 52 is locked with the button 31 and limits the driving torque of the driving piece 51 from being transmitted to the rotating shaft 21. When the button 31 is in a pressed state, the limiting piece 52 is unlocked with the button 31 and transmits the driving torque of the driving piece 51 to the rotating shaft 21.

[0095] It can be understood that the limiting piece 52 is connected to the rotating shaft 21, so that the limiting piece 52 moves and the rotating shaft 21 moves, and the limiting piece 52 is static and the rotating shaft 21 is static. When the limiting piece 52 is unlocked with the button 31, the rotating shaft 21 can be driven to rotate. When the limiting piece 52 is locked with the button 31, the limiting piece 52 limits the movement of the rotating shaft 21, so that the rotating shaft 21 remains static relative to the support 10.

[0096] Specifically, the limiting piece 52 comprises a first connecting end 521 and a second connecting end 522 opposite to the first connecting end 521. The first connecting end 521 is connected to the rotating shaft 21 of the pin 20. The second connecting end 522 is locked or unlocked with the button base 311. The limiting piece 52 further comprises a power receiving portion 523 for receiving the driving torque of the driving piece 51, so that the limiting piece 52 can transmit the driving torque to the rotating shaft 21. The power receiving portion 523 can be arranged on the first connecting end 521 or the second connecting end 522, or between the first connecting end 521 and the second connecting end 522.

[0097] In the embodiment, the driving piece 51 can release the rotating torque to the limiting piece 52. The first connecting end 521 of the limiting piece 52 can transmit the rotating torque to the rotating shaft 21, so that the pin 20 is flipped out of the support 10 relative to the support 10.

[0098] In an embodiment, the first connecting end 521 is fixedly connected to the end of the rotating shaft 21, so that the limiting piece 52 and the rotating shaft 21 rotate synchronously, and the rotating torque of the limiting piece 52 is effectively transmitted to the rotating shaft 21, avoiding idling of the limiting piece 52, so as to ensure that the pin 20 can be effectively flipped.

[0099] Optionally, the first connecting end 521 is provided with a clamping groove 524, and the end of the rotating shaft 21 is provided with a clamping plate 401 inserted into the clamping groove 524, so as to realize the fixed connection between the first connecting end 521 and the rotating shaft 21. The clamping plate 401 is arranged at the end of the rotating shaft 21 away from the pin column 22. Of course, the transmission portion 40 can also be insertedly fixed, screwingly fixed, or weldingly fixed to the rotating shaft 21.

[0100] It can be understood that the guide sliding convex 313 of the key base 311 cooperates with the guide sliding groove of the key hole 151, so that the support 10 restricts the rotation of the key 31, so that the key 31 cannot rotate relative to the support 10. When the key 31 and the second connecting end 522 of the limiting piece 52 are locked and matched, the key 31 can restrict the rotation of the limiting piece 52, that is, the limiting piece 52 is connected with the driving piece 51, and the driving torque of the driving piece 51 cannot be released through the limiting piece 52 due to the limiting action of the key 31, that is, the key 31 locks the limiting piece 52, which can limit the rotation of the transmission part 40 and the plug 20.

[0101] In another embodiment, as shown in Figure 8 , the limiting piece 52 can transmit the driving torque to the rotating shaft 21 through the transmission part 40, that is, the limiting piece 52 is indirectly connected with the rotating shaft 21. For example, the first connecting end 521 and the transmission part 40 are engaged through gears to transmit the rotating torque. The first connecting end 521 is provided with a gear, and the transmission part 40 is provided with a gear or a gear set, and the transmission part 40 is engaged with the first connecting end 521. After the limiting piece 52 receives the rotating torque of the driving piece 51, the first connecting end 521 transmits the rotating torque to the transmission part 40 through gear engagement. The transmission part 40 is provided with a gear coaxial with the rotating shaft 21, and is fixedly arranged with the rotating shaft 21, so that the transmission part 40 transmits the rotating torque to the rotating shaft 21, and finally the limiting piece 52 can transmit the rotating torque to the plug 20 in the unlocked state, so that the plug 20 can be flipped and extended relative to the support 10.

[0102] In the first embodiment, please refer to Figure 6 , Figure 7 and Figure 9, the key 31 and the limiting member 52 can be locked and matched in a clamping manner. Specifically, the end face of the key base 311 away from the key cap 312 is provided with a insertion hole 319 extending towards the key cap 312. The second connecting end 522 is inserted into the insertion hole 319 and can be slidably matched with the insertion hole 319 to facilitate the pressing of the key 31. The outer peripheral side wall of the second connecting end 522 is provided with a limiting protrusion 525. The inner peripheral side wall of the insertion hole 319 is provided with a limiting clamping groove 314 which can be matched with the limiting protrusion 525. When the key 31 is in an unpressed state, the limiting clamping groove 314 is matched with the limiting protrusion 525 to limit the rotation of the limiting member 52 relative to the key 31. At this time, the key 31 cannot rotate relative to the support 10, that is, the limiting member 52 also cannot rotate relative to the support 10. The transmission part 40 is fixed with the limiting member 52, so that the transmission part 40 is limited by the key 31 and cannot rotate relative to the support 10. That is, the rotation shaft 21 of the prong 20 is also limited by the key 31 and cannot rotate relative to the support 10. The prong 20 remains in a state of being retracted into the accommodation groove 18. When the key 31 is in a pressed state, the limiting protrusion 525 slides relative to the limiting clamping groove 314 and slides to a misaligned state, thereby unlocking the matching between the limiting member 52 and the key 31. The limiting member 52 is not limited in rotation by the key 31, and the kinetic energy of the driving member 51 can be released through the limiting member 52. That is, the limiting member 52 rotates relative to the support 10 under the driving action of the driving member 51. The limiting member 52 drives the transmission part 40 and the rotation shaft 21 to rotate, and finally drives the prong 20 to flip to a state of extending relative to the support 10. Of course, in other embodiments, the limiting member 52 and the key 31 can also be locked and matched in a magnetic attraction manner. For example, the second connecting end 522 and the key base 311 are respectively provided with two magnets which magnetically attract each other. When the key 31 is not pressed, the second connecting end 522 and the key base 311 are magnetically attracted, so that the limiting member 52 is fixed relative to the key 31, that is, the key 31 is locked and matched with the limiting member 52. When the key 31 is pressed, the second connecting end 522 and the key base 311 are separated due to the magnetic attraction force being less than the pressing force, thereby unlocking the matching between the key 31 and the limiting member 52.

[0103] Optionally, the second connecting end 522 of the limiting member 52 can be provided with a plurality of limiting protrusions 525 around the central axis of the limiting member 52, and the plurality of limiting protrusions 525 are symmetrically arranged around the central axis of the limiting member 52. The key 31 is correspondingly provided with a plurality of limiting clamping grooves 314, and the plurality of limiting clamping grooves 314 are symmetrically arranged around the central axis of the key 31.

[0104] Optionally, the central axis of the key 31, the central axis of the limiting member 52, the central axis of the transmission part 40 and the central axis of the rotation shaft 21 are coaxially arranged.

[0105] It can be understood that when the driving member 51 drives the limiting member 52 to drive the transmission part 40 and the rotating shaft 21 to rotate, the limiting protrusion 525 of the limiting member 52 is close to the bottom of the insertion hole 319 relative to the limiting slot 314, at this time, the limiting slot 314 is staggered with the limiting protrusion 525, and the key 31 is blocked by the limiting protrusion 525 and cannot be reset. After the pin 20 is manually rotated and the pin 20 is retracted in the accommodation groove 18, the rotating shaft 21 of the pin 20 drives the limiting member 52 through the transmission part 40 to rotate, so that the limiting protrusion 525 is rotated to the position aligned with the limiting slot 314, and then the limiting protrusion 525 is slid to the position matched with the limiting slot 314 again, the key 31 is reset, so as to press the key 31 next time. During the process of manually pressing the pin 20 to retract in the accommodation groove 18, the rotating torque of the pin 20 is transmitted to the driving member 51 through the transmission part 40 and the limiting member 52, so that the driving member 51 can store kinetic energy again to release the kinetic energy when the key 31 is pressed next time.

[0106] In the embodiment, please refer to Figure 6 、 Figure 7 and Figure 10 , the driving member 51 is provided with an elastic member, the elastic member is connected to the key 31 and the limiting member 52, when the key 31 is in an unpressed state, the elastic member can store the rotating torque; when the key 31 is in a pressed state, the elastic member releases the rotating torque to the limiting member 52. One end of the elastic member is fixedly connected to the key 31, and the other end is fixedly connected to the limiting member 52. The elastic member is provided with a curved arm twisted along a curve between the two ends. When the limiting protrusion 525 cooperates with the limiting slot 314, the curved arm between the two ends of the elastic member is in a pre-compressed deformation state, that is, the elastic member stores elastic torsional kinetic energy. By pressing the key 31, the limiting protrusion 525 slides relative to the limiting slot 314 to a disengaged state, the curved arm between the two ends of the elastic member begins to recover the deformation to a natural relaxed state, that is, the two ends of the elastic member move away from each other in the plane perpendicular to the sliding direction of the key 31, the elastic member releases the rotating torque, thereby driving the limiting protrusion 525 to rotate relative to the key 31 and the bracket 10, and finally making the pin 20 flip out to the extended state relative to the bracket 10. When the pin 20 is manually pressed to retract in the accommodation groove 18, the pin 20 drives the limiting member 52 to rotate relative to the key 31 through the transmission part 40, so that the two ends of the elastic member move relative to each other in the plane perpendicular to the sliding direction of the key 31, and the curved arm between the two ends of the elastic member is compressed again to a pre-compressed state, so that the elastic member stores torsional kinetic energy.

[0107] In the embodiment, the elastic member also provides a sliding reset torque to the key 31, so that the key 31 is returned to the unpressed state after being pressed. The curved arm of the elastic member between the two ends extends along a spiral curve. During the process of pressing the key 31 to slide relative to the limiting member 52, the two ends of the elastic member are compressed in the sliding direction of the key 31, that is, the elastic member stores a linear sliding torque. During the process of aligning and sliding fitting the limiting protrusion 525 and the limiting clamping groove 314, the two ends of the elastic member are opened in the sliding direction of the key 31, that is, the elastic member releases the linear sliding torque to the key 31, so that the key 31 is returned to the unpressed state. It can be understood that the elastic member is a rectangular spring. The two ends of the elastic member can store or release a rotating torque when the key 31 and the limiting member 52 rotate relative to each other, and also store or release a linear sliding torque when the key 31 and the limiting member 52 slide relative to each other, that is, one elastic member can store or release kinetic energy in two directions at the same time, increase the utilization efficiency of the elastic member, and simplify the structure of the driving assembly 50, and improve the controllability of the power adapter 100. Of course, in other embodiments, the end of the elastic member away from the key 31 can also be fixed to the transmission part 40 or fixed to the rotating shaft 21, as long as the two ends of the elastic member can store or release a rotating torque when the key 31 and the limiting member 52 rotate relative to each other, and can store or release a sliding torque when the key 31 and the limiting member 52 slide relative to each other.

[0108] Optionally, the end face of the key base 311 away from the keycap is provided with a fixed groove 315 communicating with the insertion hole 319. One end of the elastic member extends into the insertion hole 319 and is provided with a first clamping hook 511 fixed to the fixed groove 315, so as to increase the stability of the elastic member and the key 31. The first connecting end 521 of the limiting member 52 is provided with a fixed hole, and the end of the elastic member away from the key 31 is sleeved on the limiting member 52 and is provided with a second clamping hook 512 inserted into the fixed hole, so as to increase the stability of the elastic member and the limiting member 52. The fixed hole forms a power receiving part 523 of the limiting member 52, and the elastic member is stably matched with the fixed hole by the second clamping hook 512, so as to drive the limiting member 52 to rotate. Of course, in other embodiments, the end of the elastic member away from the key 31 can also be fixed to the second connecting end 522 or fixed between the first connecting end 521 and the second connecting end 522.

[0109] In another embodiment similar to the first embodiment, as shown in FIG. 6, the key base 311 is provided with a limiting protrusion 313, and the limiting member 52 is provided with a limiting clamping groove 312 corresponding to the limiting protrusion 313. The limiting protrusion 313 is arranged on the key base 311 and the limiting clamping groove 312 is arranged on the limiting member 52, so that the key 31 and the limiting member 52 are matched and fitted in a rotating manner. The elastic member is arranged between the key 31 and the limiting member 52, and the two ends of the elastic member are arranged in the limiting clamping groove 312 and the limiting protrusion 313 respectively. The elastic member is arranged to store or release a rotating torque when the key 31 and the limiting member 52 rotate relative to each other, and to store or release a linear sliding torque when the key 31 and the limiting member 52 slide relative to each other. Figure 11 and Figure 12As shown, the driving member 51 can also drive the limiting member 52 to perform linear sliding movement. The transmission part 40 connects the limiting member 52 and the rotating shaft 21 of the pin 20, so that the transmission part 40 converts the linear sliding torque of the limiting member 52 into rotating torque and transmits the rotating torque to the rotating shaft 21. Specifically, the limiting member 52 is provided with a rack, and the transmission part 40 is provided with a gear fixedly connected to the rotating shaft 21 and coaxially arranged with the rotating shaft 21. The rack on the limiting member 52 is engaged with the gear on the rotating shaft 21, or the rack on the limiting member 52 is engaged with the gear on the rotating shaft 21 through a reversing gear, or the rack on the limiting member 52 is engaged with the gear on the rotating shaft 21 through a plurality of gears engaged in sequence. The key base 311 is provided with a through hole 3119 transversely penetrating. The limiting member 52 is also provided with a guide sliding bar 529 arranged in parallel with the rack. The length direction of the limiting member 52 is perpendicular to the slidable direction of the key 31. The slidable direction of the key 31 is parallel to the axial direction of the rotating shaft 21. When the key 31 is not pressed, the guide sliding bar 529 is misaligned with the through hole 3119, the end of the guide sliding bar 529 abuts against the circumferential side of the key base 311, so that the limiting member 52, the key 31, the transmission part 40 and the rotating shaft 21 all remain in a static state relative to the support 10, that is, the limiting member 52 is locked with the key 31. When the key 31 is pressed to make the guide sliding bar 529 opposite to the through hole 3119, the driving member 51 can drive the guide sliding bar 529 to slide with the through hole 3119, that is, the limiting member 52 is unlocked with the key 31, so that the limiting member 52 obtains linear sliding torque, the rack drives the gear to rotate, the gear drives the rotating shaft 21 to rotate, and finally the pin 20 is flipped to the state of extending relative to the support 10. As an embodiment, the driving member 51 is a rectangular spring connected to the support 10 and the limiting member 52. When the key 31 is not pressed, the driving member 51 is in a compressed state. When the key 31 is pressed, the driving member 51 returns to a natural relaxed state, and then the driving member 51 releases linear sliding torque to the limiting member 52.

[0110] It can be understood that in the first embodiment or another embodiment similar to the first embodiment, the driving member 51 can be replaced by other structural components capable of storing kinetic energy, for example, the driving member 51 can be two mutually repulsive magnets, one of which is fixed to the support 10 and the other of which is fixed to the limiting member 52. By moving the limiting member 52 relative to the support 10, the two magnets are compressed or relaxed, that is, the kinetic energy is stored or released, so as to meet the requirement that the pin 20 can be flipped to extend relative to the support after the key 31 is pressed. For another example, the driving member 51 can be a piston arranged in a gas cavity, the piston fixes the limiting member 52, and by moving the limiting member 52 relative to the support, the piston slides in the gas cavity, and the gas in the gas cavity is compressed or expanded, that is, the driving member 51 stores or releases kinetic energy, so as to meet the requirement that the pin 20 can be flipped to extend relative to the support after the key 31 is pressed.

[0111] In another embodiment similar to the first embodiment, asFigure 13 As shown, the linear sliding torque of the button 31 can be directly transmitted to the rotating shaft 21 of the prong 20 through the transmission part 40, so that the prong 20 can be flipped to the state of extending relative to the support 10. Specifically, the transmission part 40 is provided with a transmission sliding block 491 fixedly connected with the button 31 and a worm 492 fixedly connected with the rotating shaft 21, and the transmission sliding block 491 is engaged with the worm 492. By pressing the button 31, the button 31 drives the transmission sliding block 491 to slide relative to the support 10, the transmission sliding block 491 drives the worm 492 to rotate, so that the worm 492 drives the rotating shaft 21 of the prong 20 to rotate, and finally realizes the prong 20 to be flipped to the state of extending relative to the support 10. After the prong 20 is flipped to the state of extending relative to the support 10, the limiting magnet provided in the support 10 and capable of magnetically attracting the transmission sliding block 491 magnetically attracts the transmission sliding block 491, so that the prong 20 is kept in the state of extending relative to the support 10. When it is needed to store the prong 20 in the storage groove 18, an acting force is applied to the prong 20, the acting force is greater than the magnetic attraction force of the limiting magnet to the transmission sliding block 491, and finally the transmission sliding block 491 is separated from the limiting magnet, the prong 20 is flipped to be stored in the storage groove 18, and the button 31 is reset, so as to be pressed next time.

[0112] The power adapter 100 of the present application can also improve the structure of the shell 90 on the basis of the first embodiment, for example, to provide another power adapter not including the shell 90, or to provide a power adapter having a shell with other structural forms, that is, the power adapter 100 of the present application is not limited to the structural form of the shell 90 on the basis of the first embodiment, and any solution that releases or limits the driving torque of the driving assembly 50 to the prong 20 by using the button 31 to make the prong 20 flip relative to the support to extend or retract is within the protection scope of the present application.

[0113] It can be understood that, referring to Figure 14 , Figure 15 and Figure 16 , the power adapter 100 of the present application further includes the transmission part 40 stored in the support 10, the transmission part 40 is connected to the moving part 30 and the prong 20, so as to convert the movement torque of the moving part 30 into a rotating torque transmitted to the prong 20, so that the prong 20 is flipped relative to the shell 90. That is, by moving the moving part 30 relative to the support 10, the moving part 30 drives the prong 20 to extend or retract relative to the support 10.

[0114] The second embodiment is provided, which is different from the first embodiment. The moving part 30 is slidably arranged on the support 10 and located outside the accommodating groove 18. The transmission part 40 converts the linear sliding torque of the moving part 30 into the rotating torque and transmits the rotating torque to the rotating shaft 21 of the plug 20. The moving part 30 can slide linearly relative to the support 10. The moving part 30 is directly connected with the transmission part 40, so that the linear sliding torque of the moving part 30 can be transmitted to the transmission part 40. The transmission part 40 is directly connected with the rotating shaft 21, so that the transmission part 40 can transmit the rotating torque to the rotating shaft 21, and the rotating shaft 21 rotates relative to the support 10.

[0115] In the embodiment, the moving part 30 is provided with a sliding cover 32 arranged on the side of the support 10 away from the accommodating groove 18. The accommodating groove 18 is arranged on the side of the first shell 101 away from the second shell 102. The sliding cover 32 is slidably connected with the second shell 102. The sliding direction of the sliding cover 32 is parallel to the first side surface 15 and perpendicular to the rotating shaft 21. The sliding cover 32 is stacked on the second shell 102. The sliding cover 32 can slide to a position completely covering the second shell 102, and can slide to a position partially overlapping the second shell 102. The sliding cover 32 covers the side of the outer shell 90 away from the through groove 91. The sliding cover 32 is slidably connected with the second shell 102 through the outer shell 90.

[0116] As an implementation form, as shown in Figure 17 , when the sliding cover 32 slides to the position completely covering the second shell 102, the plug 20 is flipped to the extended state relative to the support 10. As shown in Figure 16 , when the sliding cover 32 slides to the position partially overlapping the second shell 102, the plug 20 is flipped to the retracted state relative to the support 10. Of course, in other embodiments, the sliding cover 32 can slide to the position completely covering the second shell 102, and the plug 20 can be flipped to the retracted state relative to the support 10; the sliding cover 32 can slide to the position partially overlapping the second shell 102, and the plug 20 can be flipped to the extended state relative to the support 10.

[0117] Please refer to Figure 16 , Figure 17 and Figure 18 . Optionally, the first side surface 15 and the second side surface 16 are both in the shape of a circular arc. The sliding cover 32 is provided with two opposite curved side edges. The curved side edges extend in the shape of a circular arc. The two opposite curved side edges are respectively aligned with the two opposite side edges of the second shell 102, so that the overall appearance of the power adapter 100 is simplified.

[0118] Optionally, the accommodation groove 18 also penetrates the first end surface 13 of the support 10, so as to facilitate cleaning of dust and impurities in the accommodation groove 18. The rotating shaft 21 is located approximately in the middle of the first end surface 13 and the second end surface 14, so that, after the prong 20 is flipped to the state of extending relative to the support 10, the prong 20 is approximately opposite to the center of the first housing 101, and then the support 10 is facilitated to exert a plugging force on the prong 20, so as to facilitate plugging of the prong 20 with the power socket.

[0119] Optionally, as shown in Figure 18 、 Figure 20 and Figure 21 , the second housing 102 is provided with two opposite sliding grooves 1021. The two sliding grooves 1021 are adjacent to the first side surface 15 and the second side surface 16, respectively. The sliding cover 32 is provided with two sliding protrusions 321, which are in sliding cooperation with the two sliding grooves 1021, respectively, so as to realize sliding guidance of the sliding cover 32 relative to the second housing 102, and limit movement of the sliding cover 32 in the width direction of the support 10, which is the direction opposite to the first side surface 15 and the second side surface 16. The inner side of the second housing 102 is provided with clamping flanges 1022 adjacent to the two sliding grooves 1021, respectively. The sliding protrusions 321 pass through the guide and sliding clamps 322 of the sliding grooves 1021. The guide and sliding clamps 322 are clamped to the clamping flanges 1022, so as to limit movement of the sliding cover 32 in the thickness direction of the support 10, which is the direction opposite to the front surface 11 and the back surface 12.

[0120] Optionally, the second housing 102 is provided with a guide and sliding through hole 1023. The guide and sliding through hole 1023 is located between the two bearing protrusions 104. The sliding cover 32 is provided with a connecting portion 323 passing through the guide and sliding through hole 1023. The connecting portion 323 connects the transmission portion 40. The guide and sliding through hole 1023 guides the sliding of the connecting portion 323, and facilitates connection of the sliding cover 32 with the transmission portion 40, so as to ensure that the linear sliding torque of the sliding cover 32 can be transmitted to the transmission portion 40.

[0121] Of course, in other embodiments, the sliding cover 32 can also be slidingly arranged on the first side surface 15 or the second side surface 16 of the support 10, and the sliding cover 32 is controlled by the user sliding on the side of the power adapter 100, so as to realize quick and convenient extension or retraction of the prong 20.

[0122] In this embodiment, please refer to Figure 16 、 Figure 17 and Figure 18The transmission part 40 is provided with a push block 41 fixedly connected with the connecting part 323 and a rocker 42 rotatably and slidably connected with the push block 41 at one end. The end of the rocker 42 away from the push block 41 is fixedly arranged with the rotating shaft 21 of the plug 20 to drive the plug 20 to rotate. The end of the rocker 42 is slidably connected with the push block 41 towards or away from the sliding cover 32, and the rocker 42 also rotates relative to the sliding cover 32 with the end connected with the push block 41 as the rotating shaft 21. The rotating shaft of the rocker 42 relative to the sliding cover 32 is parallel to the rotating shaft 21. When the sliding protrusion 321 of the sliding cover 32 slides to the closed end of the sliding groove 1021, the end of the rocker 42 slides away from the sliding cover 32 relative to the push block 41, and the plug 20 is flipped to the retracted or extended state relative to the support 10. When the sliding protrusion 321 of the sliding cover 32 slides to the position away from the two closed ends of the sliding groove 1021, the end of the rocker 42 slides towards the sliding cover 32 relative to the push block 41, and the plug 20 is flipped to the position of half rotation, i.e. the plug 20 is flipped to the state of being substantially inclined relative to the support 10.

[0123] Optionally, the rocker 42 extends along the radial direction of the rotating shaft 21. The direction in which the end of the rocker 42 slides relative to the push block 41 is parallel to the thickness direction of the support 10.

[0124] Optionally, the rocker 42 is integrally arranged with the rotating shaft 21 to increase the stability of the rocker 42 and the rotating shaft 21.

[0125] In the embodiment, please refer to Figure 18 、 Figure 20 、 Figure 22 The push block 41 is provided with a rotating shaft sliding groove 411, and the end of the rocker 42 is provided with a slidable rotating shaft 421 slidably and rotatably connected with the rotating shaft sliding groove 411. The slidable rotating shaft 421 extends transversely from the end of the rocker 42 away from the rotating shaft 21. The slidable rotating shaft 421 is parallel to the rotating shaft 21. When the sliding cover 32 slides relative to the second housing 102, the slidable rotating shaft 421 slides in the rotating shaft sliding groove 411 and rotates with the center axis of the slidable rotating shaft 421 as the rotating shaft. The rocker 42 rotates relative to the second housing 102 and drives the rotating shaft 21 to rotate.

[0126] Optionally, the push block 41 is provided with two opposite clamping plates 412 and reinforcing ribs 413 fixedly arranged on the two clamping plates 412 respectively. The reinforcing ribs 413 are arranged on the side of the clamping plates 412 away from the other clamping plate 412. The rotating shaft sliding groove 411 is arranged between the two clamping plates 412. The two clamping plates 412 guide the slidable rotating shaft 421 to slide and rotate.

[0127] Optionally, as Figure 16 、 Figure 17 and Figure 18As shown, the rocker 42 is provided with two connecting rods 422 which are arranged side by side along the axial direction of the rotating shaft 21. The slidable rotating shaft 421 is fixed to the ends of the two connecting rods 422 which are away from the rotating shaft 21, so as to make the slidable rotating shaft 421 stable in structure.

[0128] It can be understood that the linear sliding moment of the sliding cover 32 relative to the second housing 102 is decomposed into a linear moment along the thickness direction of the bracket 10 and a rotating moment about the rotating shaft 21. The rocker 42 transmits the rotating moment to the rotating shaft 21, so that the rotating shaft 21 rotates, and finally the plug 20 can be flipped out or retracted relative to the bracket 10.

[0129] Further, in the second embodiment, please refer to Figure 16 、 Figure 17 、 Figure 19 and Figure 22 The power adapter 100 includes a first damping member 71 arranged in the bracket 10 and a second damping member 72 arranged in the plug 20. The first damping member 71 is used to provide a damping force to resist the movement of the second damping member 72, so that the plug 20 is blocked from being flipped relative to the bracket 10.

[0130] When the moving part 30 slides linearly relative to the bracket 10, the second damping member 72 rotates with the rotating shaft 21 of the plug 20 relative to the bracket 10, i.e. the second damping member 72 rotates about the axis of the rotating shaft 21 and rotates in cooperation with the first damping member 71. The first damping member 71 is located in the tangential direction of the circular arc rotating track of the second damping member 72. When the second damping member 72 rotates to be close to and abut against the first damping member 71, the first damping member 71 exerts a damping force on the second damping member 72, so that the rotation of the second damping member 72 with the rotating shaft 21 is blocked, and further the rotation of the plug 20 relative to the bracket 10 is blocked. By cooperation of the first damping member 71 and the second damping member 72, a resistance is generated during the process of the plug 20 being flipped out or retracted relative to the bracket 10, so as to avoid a large impact on the bracket 10 when the plug 20 is stopped from being extended or retracted relative to the bracket 10.

[0131] Optionally, the first damping member 71 is arranged on the inner side of the first housing 101 opposite to the rotating shaft 21. The second damping member 72 is arranged on the circumferential side of the rotating shaft 21. The second damping member 72 is arranged on the circumferential side of the rotating shaft 21 opposite to the rocker 42.

[0132] Optionally, the first damping member 71 is a damping boss arranged inside the first housing 101. The second damping member 72 is a rotating boss arranged around the rotating shaft 21. The second damping member 72 extends along the radial direction of the rotating shaft 21. When the sliding cover 32 slides relative to the second housing 102, the rotating shaft 21 rotates relative to the support 10. When the second damping member 72 slides along the rotating shaft 21 to be close to the first housing 101, the second damping member 72 tightly contacts the first damping member 71. The contact force between the second damping member 72 and the first damping member 71 increases as the distance between the second damping member 72 and the first housing 101 decreases.

[0133] It can be understood that when the second damping member 72 rotates to just contact the first damping member 71, the slidable rotating shaft 421 of the rocker 42 slides in the rotating shaft sliding groove 411 to be away from the sliding cover 32, and the prong 20 is flipped to the extended or retracted state relative to the support 10. At this time, the damping force of the first damping member 71 on the second damping member 72 is the smallest. When the second damping member 72 rotates to the state that the contact force between the first damping member 71 and the second damping member 72 is the largest, the slidable rotating shaft 421 of the rocker 42 slides in the rotating shaft sliding groove 411 to be close to the sliding cover 32, and the prong 20 is flipped to the state of being substantially inclined relative to the support 10. At this time, the damping force of the first damping member 71 on the second damping member 72 is the largest.

[0134] Specifically, the end of the first damping member 71 is provided with two first teeth 711, and a damping groove is formed between the two first teeth 711. The end of the second damping member 72 is provided with a second tooth 721 which can be in contact with the damping groove. When the second tooth 721 rotates with the rotating shaft 21 to contact the first tooth 711, the first tooth 711 hinders the second tooth 721 from continuing to rotate with the rotating shaft 21, so that there is a pause during the rotation of the rotating shaft 21. When the second tooth 721 rotates to be in contact with the damping groove, the two first teeth 711 clamp the second tooth 721, so that there is a pause during the rotation of the rotating shaft 21, so that the sliding cover 32 needs to overcome the damping force of the first damping member 71 and the second damping member 72 to make the prong 20 extend or retract relative to the support 10, so as to improve the control feeling of the sliding sliding cover 32.

[0135] More specifically, the end of the first tooth 711 is arc-shaped and protrudes, or / and the end of the second tooth 721 is arc-shaped and protrudes, so that when the first tooth 711 and the second tooth 721 rotate, the second tooth 721 can slide relative to the surface of the first tooth 711, so as to realize the cooperation between the second tooth 721 and the damping groove. Of course, in other embodiments, the first damping member 71 can be provided with three or more first teeth 711.

[0136] The third embodiment is provided in the present application, please refer to Figure 23 、 Figure 24 andFigure 25 The difference between the second embodiment and the first embodiment is that the transmission part 40 is provided with a rack 43 fixedly connected with the moving part 30 and a plurality of gears 44 sequentially engaged with each other, the first gear 44 is engaged with the rack 43, and the last gear 44 is fixedly connected with the rotating shaft 21 of the plug 20 and coaxially arranged with the rotating shaft 21 of the plug 20. The rack 43 slides along the straight line relative to the support 10 with the moving part 30, the rack 43 drives the first gear 44 to rotate, and then drives the last gear 44 to rotate, the last gear 44 drives the rotating shaft 21 to rotate, and finally drives the plug 20 to flip and extend or retract relative to the support 10.

[0137] In the embodiment, the rack 43 is fixed on the connecting part 323 of the sliding block. The rack 43 is located on the side of the sliding cover 32 facing the second shell 102. The length direction of the rack 43 is parallel to the sliding direction of the sliding cover 32. The transmission part 40 is provided with a first gear 441 rotatably connected with the support 10 and engaged with the rack 43, and a second gear 442 fixedly connected with the rotating shaft 21 and coaxially arranged with the rotating shaft 21. The second gear 442 is engaged with the first gear 441. The first gear 441 constitutes the first gear 44, and the second gear 442 constitutes the last gear 44. The rotating shaft end of the first gear 441 is clamped between the bearing boss 103 and the bearing protrusion 104. The second gear 442 is fixed at the middle position of the rotating shaft 21, so that the rotating shaft 21 receives the rotating torque at the middle position, so that the rotating shaft 21 balances the rotation. The outer diameter of the first gear 441 is larger than the outer diameter of the second gear 442, so that after the sliding cover 32 slides a small distance, the second gear 442 can rotate about 90°, and the plug 20 is flipped and extended.

[0138] Optionally, the rack 43 is integrally arranged with the sliding cover 32.

[0139] Optionally, the first gear 441 is rotatably arranged between the two bearing bosses 103 and the two bearing protrusions 104.

[0140] Optionally, the sliding cover 32 partially covers the second shell 102.

[0141] Optionally, the surface of the sliding cover 32 away from the second shell 102 is provided with a boss 329, and the boss 329 facilitates the sliding cover 32 to receive the pushing and pulling force.

[0142] When the sliding cover 32 slides to be flush with the end edge of the second shell 102, the plug 20 is flipped to the retracted state relative to the support 10. When the sliding cover 32 slides to be substantially opposite to the center of the second shell 102, the plug 20 is flipped to the extended state relative to the support 10. The rotating shaft 21 of the plug 20 is substantially opposite to the center of the first shell 101, so that after the plug 20 is extended relative to the support 10, it is convenient to be inserted into the power socket.

[0143] Of course, in other embodiments, the transmission part 40 can also be provided with a gear 44 fixedly connected to the rotating shaft 21 and coaxially arranged with the rotating shaft 21, and the gear 44 is also engaged with the rack 43. When the sliding cover 32 drives the rack 43 to slide, the gear 44 rotates under the action of the rack 43 and drives the rotating shaft 21 to rotate.

[0144] In other embodiments, the transmission part 40 can also be provided with a gear engaged with the first gear 441 and the second gear 442, or more gears engaged in sequence between the first gear 441 and the second gear 442, the first gear 441 constitutes the first end gear, and the second gear 442 constitutes the last end gear.

[0145] Further, please refer to Figure 26 、 Figure 27 and Figure 28 , in the third embodiment, different from the second embodiment, the first damping member 71 is provided with two opposite elastic pieces 712, the two elastic pieces 712 form a clamping groove therebetween, the second damping member 72 is arranged on the moving part 30, and the second damping member 72 is provided with a protrusion 722 matched with the clamping groove. The second damping member 72 slides linearly relative to the first damping member 71 along with the moving part 30. During the sliding process of the second damping member 72, the elastic clamping force of the two elastic pieces 712 on the protrusion 722 forms the damping force of the second damping member 72. The two elastic pieces 712 are fixed to the inner side of the second support 10 and are respectively located on both sides of the guide sliding through hole 1023. The protrusion 722 is fixed to one side of the sliding cover 32 connected with the rack 43.

[0146] Optionally, the inner side of the second housing 102 is provided with two opposite fixed bosses 1029. The two elastic pieces 712 are respectively fixed to the two fixed bosses 1029 and are respectively located on the side of the two fixed bosses 1029 close to each other.

[0147] Optionally, the protrusion 722 is arranged on the connecting part 323 of the sliding cover 32. The protrusion 722 protrudes on the connecting part 323 respectively towards the two fixed bosses 1029, so as to facilitate the protrusion 722 to abut and match with the two elastic pieces 712 respectively. The protrusion 722 is integrally arranged with the sliding cover 32.

[0148] Optionally, the rack 43 is arranged on the side of the protrusion 722 away from the sliding cover 32, so as to facilitate the rack 43 to engage with the first gear 441. The rack 43 is integrally arranged with the protrusion 722.

[0149] Specifically, the fixed boss 1029 is provided with two fixed clamping grooves 1028. The two fixed clamping grooves 1028 are oppositely arranged in the sliding direction of the parallel sliding cover 32. The two ends of the elastic sheet 712 are respectively provided with two fixed clamping hooks 713, and the two fixed clamping hooks 713 are stably matched with the two fixed clamping grooves 1028. The elastic sheet 712 is provided with a first arch portion 714 between the two fixed clamping hooks 713. The first arch portion 714 is an arch portion with a bent line end. The first arch portion 714 can be elastically deformed under the action of a resisting force. The first arch portion 714 of one of the elastic sheets 712 arches towards the other elastic sheet 712. The two first arch portions 714 form a clamping area. The lug 722 is provided with a second arch portion 723 on the side facing the elastic sheet 712. When the lug 722 passes through the clamping area and the second arch portion 723 is in contact with the first arch portion 714, the first damping member 71 prevents the second damping member 72 from sliding.

[0150] It can be understood that when the second arch portion 723 slides with the lug 722 to just contact the first arch portion 714, the first arch portion 714 begins to deform, the sliding of the sliding cover 32 is blocked, the plug 20 is blocked from turning and rotating from the retracted state to the extended state, and if the sliding cover 32 continues to slide, the resistance will become larger and larger. When the arching end point of the second arch portion 723 continues to slide with the lug 722 to contact the arching end point of the second arch portion 723, the degree of deformation of the first arch portion 714 is the largest, the resistance to the sliding of the lug 722 is the largest, at this time, the sliding of the sliding cover 32 has a pause, and the plug 20 is turned to the inclined state relative to the support 10. When the arching end point of the second arch portion 723 continues to slide with the lug 722 to slide past the arching end point of the second arch portion 723, the first arch portion 714 begins to deform towards the natural relaxed state, the resistance to the sliding of the lug 722 gradually decreases, and at this time, the second arch portion 723 will slide quickly under the elastic restoring force of the first arch portion 714, so that the sliding cover 32 slides quickly, and the plug 20 quickly turns to the extended state relative to the support 10. Since the plug 20 is turned to the extended state relative to the support 10, the first arch portion 714 has a limiting and pressing effect on the second arch portion 723, preventing the lug 722 and the sliding cover 32 from retreating, and using the transmission relationship of the sliding cover 32, the transmission portion 40 and the plug 20, the plug 20 is locked, so that the plug 20 remains in the extended state relative to the support 10.

[0151] More specifically, as Figure 28As shown, the elastic piece 712 includes a first inclined section 715 and a second inclined section 716 which is bent relative to the first inclined section 715. When the slider 32 drives the plug 20 to slide from the retracted state to the extended state, the protrusion 722 first contacts the first inclined section 715 and is finally locked by the second inclined section 716. The arch end point of the first arch portion 714 is formed at the joint point of the first inclined section 715 and the second inclined section 716. The first distance L is set between the end point of the first inclined section 715 and the arch end point of the first arch portion 714 in parallel to the sliding direction of the slider 32. The second distance H is set between the end point of the first inclined section 715 and the arch end point of the first arch portion 714 in perpendicular to the sliding direction of the slider 32. The second inclined section 716 is inclined to the sliding direction of the slider 32 by the angle A. By adjusting the first distance L, the resistance stroke and the fast sliding stroke of the slider 32 during the sliding process can be adjusted. By adjusting the second distance H, the elastic resistance force of the elastic piece 712 to the protrusion 722 can be adjusted, so as to adjust the sliding damping force of the slider 32. By adjusting the angle A, the locking force of the elastic piece 712 to the slider 32 can be adjusted.

[0152] Please refer to Figure 29 、 Figure 30 The fourth embodiment is provided in the present application, which is substantially the same as the third embodiment, except that the slider 32 covers a part of the second housing 102, so that the side of the second housing 102 is exposed relative to the slider 32, and the side of the support 10 is exposed relative to the slider 32, so as to improve the appearance performance. The transmission part 40 further includes a sliding rack 450 which is engaged with the second gear 442. Please refer to Figure 31 and Figure 32 Further difference is that the outer diameter of the second gear 442 is larger than the outer diameter of the first gear 441, and the axis of the first gear 441 is closer to the first housing 101 than the axis of the second gear 442. As Figure 33 and Figure 34As shown, the outer diameter of the second gear 442 is greater than the outer diameter of the first gear 441, so that the sliding stroke of the sliding rack 450 is smaller than the sliding stroke of the sliding cover 32, so as to facilitate the damping cooperation of the second damping member 72 on the sliding rack 450 with the first damping member 71. The second damping member 72 is arranged on the sliding rack 450. The sliding rack 450 is slidingly arranged inside the first housing 101 and slides relative to the first housing 101 under the rotation of the second gear 442. The sliding direction of the sliding rack 450 is opposite to the sliding direction of the rack 43. When the sliding cover 32 drives the rack 43 to slide away from the end surface of the support 10, the sliding rack 450 slides towards the end surface of the support 10. When the sliding cover 32 drives the rack 43 to slide towards the end surface of the support 10, the sliding rack 450 slides away from the end surface of the support 10. By arranging the second damping member 72 on the sliding rack 450, the transmission part 40 can effectively obtain damping force, effectively prevent the movement of the transmission part 40, and effectively lock and limit the prong 20 when it is turned to the extended state or the retracted state.

[0153] Specifically, please refer to Figure 33 and Figure 34 The first damping member 71 is provided with a first locking boss 717 fixed inside the first housing 101 and a second locking boss 718 opposite to the first locking boss 717. The first locking boss 717 is provided with a first clamping groove, and the second locking boss 718 is provided with a second clamping groove. The opposite direction of the first locking boss 717 and the second locking boss 718 is parallel to the sliding direction of the sliding cover 32. The first locking boss 717 and the second locking boss 718 are adjacent to the first end surface 13 and the second end surface 14 of the support 10, respectively. The second damping member 72 is provided with a first elastic buckle 7230 and a second elastic buckle 724 fixed at both ends of the sliding rack 450. The first elastic buckle 7230 and the second elastic buckle 724 can be made of materials with elastic deformation performance. When the sliding cover 32 drives the prong 20 to turn relative to the support 10, the sliding rack 450 slides to be adjacent to the first end surface 13, the first elastic buckle 7230 is clamped with the first clamping groove, and the second elastic buckle 724 is separated from the second clamping groove, so that the sliding rack 450 remains in the locked position with the first housing 101, and the prong 20 remains in the extended state relative to the support 10. When the sliding cover 32 drives the prong 20 to retract relative to the support 10, the sliding rack 450 slides to be adjacent to the second end surface, the second elastic buckle 724 is clamped with the second clamping groove, and the first elastic buckle 7230 is separated from the first clamping groove, so that the sliding rack 450 remains in the locked position with the first housing 101, and the prong 20 remains in the retracted state relative to the support 10.

[0154] It can be understood that, in the process of the first elastic buckle 7230 being buckled into the first buckle slot, the first elastic buckle 7230 first contacts the first locking boss 717 and gradually starts to deform, and finally buckles into the first buckle slot and returns to the natural relaxed state, so that when the sliding cover 32 drives the plug 20 to flip relative to the support 10 to the extended state, there is a pause at first and finally stabilizes at the position of sliding to the end locking. Similarly, in the process of the second elastic buckle 724 being buckled into the second buckle slot, the second elastic buckle 724 first contacts the second locking boss 718 and gradually starts to deform, and finally buckles into the second buckle slot and returns to the natural relaxed state, so that when the sliding cover 32 drives the plug 20 to flip relative to the support 10 to the retracted state, there is a pause at first and finally stabilizes at the position of sliding to the end locking.

[0155] Please refer to Figure 35 , Figure 36 and Figure 37 , the fifth embodiment is provided, which is substantially the same as the third embodiment, except that the transmission part 40 is provided with a rack 43 fixedly connected with the sliding cover 32 and slidingly arranged in the first housing 101, and a gear 44 fixed to the rotating shaft 21 and coaxially arranged with the rotating shaft 21, the gear 44 being engaged with the rack 43.

[0156] Specifically, the connecting part 323 of the sliding cover 32 is provided with a first connecting shaft 324 and a second connecting shaft 325 arranged side by side with the first connecting shaft 324. The first connecting shaft 324 and the second connecting shaft 325 pass through the shell 90. The first connecting shaft 324 and the second connecting shaft 325 are oppositely arranged in the sliding direction of the sliding cover 32. The second housing 102 is provided with two sliding guide through holes 1023. The first connecting shaft 324 and the second connecting shaft 325 pass through the two sliding guide through holes 1023 and slide in the two sliding guide through holes 1023, respectively. The sliding rack 450 is slidingly arranged on the inner side of the first housing 101. The sliding rack 450 is provided with a connecting boss 451 protruding towards the second housing 102. The end of the connecting boss 451 is provided with a first matching hole and a plug column 453 opposite to the first matching hole, and the second connecting shaft 325 is provided with a second matching hole. The first connecting shaft 324 is inserted into the first matching hole, and the plug column 453 is inserted into the second matching hole, so that the sliding cover 32 and the rack 43 are stably matched through the hole shaft. The rack 43 is provided with a plurality of arranged transmission serrations at one end of the connecting boss 451, so that the transmission serrations of the rack 43 are engaged with the transmission serrations of the gear 44.

[0157] Optionally, please refer to Figure 35 and Figure 38The inner side of the first shell 101 is provided with a rack sliding groove 1019 for slidingly guiding the rack 43. The two opposite inner side walls of the rack sliding groove 1019 slidingly guide the rack 43. The inner wall of the rack sliding groove 1019 is provided with a first positioning groove and a second positioning groove opposite to the first positioning groove. The outer side wall of the rack 43 is provided with a positioning protrusion. The positioning protrusion has elastic deformation performance. When the positioning protrusion slides to cooperate with the first positioning groove, the prong 20 is flipped to retract relative to the outer shell 90. When the positioning protrusion slides to cooperate with the second positioning groove, the prong 20 is flipped to extend relative to the outer shell 90. When the positioning protrusion abuts against the inner wall of the rack sliding groove 1019, there is a damping force when the rack 43 slides in the rack sliding groove 1019, so that there is a resistance feeling during the sliding of the sliding cover 32.

[0158] Please refer to Figure 39 、 Figure 40 and Figure 41 The sixth embodiment is substantially the same as the third embodiment, except that the moving part 30 is provided with a sliding key 33, which is arranged on the support 10 and located outside the accommodation groove 18. The sliding key 33 is arranged on the support 10 to slide along a straight line. The sliding key 33 penetrates the side surface 943 of the outer shell 90. The sliding direction of the sliding key 33 is parallel to the length direction of the outer shell 90. The sliding key 33 is connected with the transmission part 40 and transmits the straight line sliding torque to the transmission part 40. The transmission part 40 converts the straight line sliding torque of the sliding key 33 into a rotating torque and transmits the rotating torque to the rotating shaft 21. The sliding key 33 is a sliding control key on the support 10. The user can control the prong 20 to flip relative to the support 10 to the extended or retracted state by sliding the sliding key 33.

[0159] Optionally, the sliding key 33 is arranged on the first side surface 15 or the second side surface 16 of the support 10 to slide.

[0160] Optionally, the sliding key 33 partially extends out of the support 10, so that the part of the sliding key 33 extending out of the support 10 can receive a sliding push-pull force.

[0161] Specifically, the edge of the first shell 101 is provided with a first strip-shaped groove, and the edge of the second shell 102 is provided with a second strip-shaped groove. The first strip-shaped groove and the second strip-shaped groove jointly form a sliding guide groove 331 of the sliding key 33. The sliding guide groove 331 is arranged on the first side surface 15 or the second side surface 16, so that the user can slide and control the sliding key 33 on the side of the power adapter 100, achieving the effect of convenience, speediness and labor saving.

[0162] The sliding key 33 comprises a sliding base 332 and a sliding key cap 333 arranged on the sliding base 332. The sliding base 332 is in the state of a rectangular plate.

The sliding key cap 333 is in the state of a rectangular boss. The length direction of the sliding key cap 333 is parallel to the length direction of the sliding base 332. The length of the sliding key cap 333 is less than the length of the sliding base 332. The end of the sliding key cap 333 extends out of the support 10. When the sliding key cap 333 slides from one end to the other end of the sliding guide groove 331, the sliding base 332 always covers the sliding guide groove 331, so as to avoid the sliding guide groove 331 from entering dust and impurities into the accommodating cavity 17. The side of the sliding base 332 away from the sliding key cap 333 is connected with the transmission part 40, so as to transmit the sliding torque of the sliding key 33 to the transmission part 40.

[0163] Optionally, a plurality of sawteeth in the state of a wavy curve are arranged on the end face of the end of the sliding key cap 333 away from the sliding base 332. The plurality of sawteeth are arranged along the length direction of the sliding key cap 333, so as to facilitate the user to push the sliding key cap 333.

[0164] In the embodiment, please refer to Figure 41 , Figure 42 and Figure 43 , the transmission part 40 is provided with a rack 43 fixed to the sliding base 332, a first gear 441 meshing with the rack 43 and rotationally connected with the support 10, a second gear 442 meshing with the first gear 441 and rotationally connected with the support 10, a reversing gear 45 meshing with the second gear 442 and rotationally connected with the support 10, and a third gear 443 meshing with the reversing gear 45 and fixedly connected with the rotating shaft 21, the third gear 443 being coaxially arranged with the rotating shaft 21. The first gear 441 is formed at the gear meshing with the first end of the rack 43, and the third gear 443 is formed at the gear fixedly connected with the end of the rotating shaft 21. The rack 43 drives the first gear 441, the second gear 442, the reversing gear 45 and the third gear 443 to rotate by the sliding of the sliding key 33, so as to finally control the extension or the overturning of the plug 20 relative to the support 10. The rotation axis of the first gear 441 is parallel to the direction in which the front face 11 and the back face 12 of the support 10 face each other. The rotation axis of the second gear 442 is parallel to the rotation axis of the first gear 441. The rotation axis of the reversing gear 45 is parallel to the rotation axis of the second gear 442. The reversing gear 45 is provided with a bottom gear meshing with the second gear 442 and a conical gear coaxial with the bottom gear. The conical gear meshes with the third gear 443.

[0165] Optionally, the rotation axis of the first gear 441 is rotationally connected with the first housing 101 and the second housing 102 at both ends thereof. The rotation axis of the second gear 442 is rotationally connected with the first housing 101. The rotation axis of the reversing gear 45 is rotationally connected with the first housing 101 and the second housing 102 at both ends thereof.

[0166] Optionally, the outer diameter of the second gear 442 is smaller than the outer diameter of the first gear 441.

[0167] Optionally, the rack 43 is integrally arranged with the sliding base 332.

[0168] Optionally, the motion part 30 is provided with two sliding keys 33, and the two sliding keys 33 are respectively arranged on the first side surface 15 and the second side surface 16 of the support 10. The power adapter 100 includes two transmission parts 40, and the two transmission parts 40 are respectively connected to the two sliding keys 33. The two third gears 443 are respectively fixed to the two ends of the rotating shaft 21, so that the two sliding keys 33 can be used to quickly control the plug 20 to be flipped relative to the support 10.

[0169] It can be understood that, by using the first gear 441 with a larger outer diameter than the second gear 442, a larger transmission ratio can be achieved, so that the sliding key 33 can drive the plug 20 to be flipped and extended relative to the support 10 after sliding a small distance.

[0170] Of course, in other embodiments, a gear or more gears can be arranged between the first gear 441 and the third gear 443 to increase the transmission effect of the transmission part 40 and meet more use requirements.

[0171] Please refer to Figure 44 and Figure 45 In another embodiment similar to the sixth embodiment, the rack 43 is engaged with the gear 44 fixed to the rotating shaft 21. The rack 43 is provided with an inclined sawtooth surface, and the sawtooth surface is arranged with a plurality of first transmission sawteeth. The gear 44 fixed to the rotating shaft 21 is coaxially arranged with the rotating shaft 21, and the gear 44 is provided with an inclined conical sawtooth surface, and the conical sawtooth surface is arranged with a plurality of transmission sawteeth. The rack 43 is engaged with the gear 44, thereby simplifying the structure of the transmission part 40 between the sliding key 33 and the plug 20, and making the power adapter 100 more lightweight and compact.

[0172] Please refer to Figure 46 and Figure 47 The seventh embodiment provided by the present application is substantially the same as the third embodiment, except that the motion part 30 is provided with a pressing cover 34, and the pressing cover 34 is slidingly arranged at the end of the support 10. After receiving the pressing force of the user, the pressing cover 34 can slide along a straight line relative to the shell 90. The pressing cover 34 transmits the straight-line sliding torque to the transmission part 40, and the transmission part 40 converts the straight-line sliding torque into a rotating torque and transmits the rotating torque to the rotating shaft 21.

[0173] Optionally, the pressing cover 34 is slidingly arranged on the first end surface 13 or the second end surface 14. The sliding direction of the pressing cover 34 is parallel to the normal direction of the first end surface 13 or the second end surface 14.

[0174] Optionally, the pressing cover 34 completely covers the first end surface 13 or the second end surface 14.

[0175] Specifically, referring to Figure 48 、 Figure 49 and Figure 50 , the bracket 10 is provided with a guide sliding hole 171 extending into the receiving cavity 17 at the first end surface 13. The pressing cover 34 includes a pressing cover plate 341 and a sliding protrusion 342 arranged on the pressing cover plate 341. The sliding protrusion 342 is in sliding fit with the guide sliding hole 171. The pressing cover plate 341 can cover the first end surface 13. The pressing cover plate 341 is provided with a connecting portion 323 connected with the transmission portion 40 on the side facing the receiving groove 18. When the pressing cover 34 is pressed to be retracted towards the bracket 10, the pressing cover 34 transmits a sliding torque to the transmission portion 40, the transmission portion 40 drives the rotating shaft 21 to rotate, and drives the insertion foot 20 to be flipped to the extended state relative to the shell 90. When the pressing cover 34 is restored to the extended state relative to the bracket 10, the transmission portion 40 drives the insertion foot 20 to be flipped to the retracted state relative to the shell 90.

[0176] Optionally, the connecting portion 323 is provided with an insertion rod 3231. The insertion rod 3231 is inserted with the transmission portion 40 to transmit the sliding torque of the pressing cover 34 to the transmission portion 40.

[0177] In this embodiment, the transmission portion 40 includes a rack 43 fixedly connected with the pressing cover 34 and a gear 44 engaged with the rack 43 and fixed to the rotating shaft 21. The gear 44 is coaxially arranged with the rotating shaft 21. The rack 43 is slidingly arranged on the first shell 101. The end portion of the rack 43 is fixedly connected with the connecting portion 323. The length direction of the rack 43 is parallel to the sliding direction of the pressing cover 34. The gear 44 is fixed to the rotating shaft 21 and located between the two insertion foot columns 22.

[0178] Optionally, the end portion of the rack 43 is provided with a connecting protrusion 432, and the connecting protrusion 432 is provided with a connecting insertion hole 433 inserted with the insertion rod 3231, so that the insertion rod 3231 is stably connected with the pressing cover 34.

[0179] Optionally, the first shell 101 is provided with a rack sliding groove 1019 for slidingly guiding the rack 43.

[0180] Further, in this embodiment, the power adapter 100 further includes an elastic restoring member 80 elastically connected between the shell 90 and the rack 43, and the elastic restoring member 80 is used to provide an elastic restoring force for restoring the pressing cover 34 to the extended state relative to the bracket 10.

[0181] The first housing 101 is provided with a fixed baffle 1018 at an end of the rack slot 1019 away from the pressing cover 34. One end of the elastic return member 80 is fixed against the fixed baffle 1018, and the other end is fixed against an end of the rack 43 away from the connecting portion 323. When the pressing cover 34 is pressed to retract relative to the support 10, the rack 43 compresses the elastic return member 80, so that the elastic return member 80 is elastically deformed. When the pressing force of the pressing cover 34 is removed, the elastic return member 80 returns to the natural relaxed state, so that the rack 43 pushes the pressing cover 34 to extend relative to the outer shell 90. Of course, in other embodiments, the elastic return member 80 can also be connected between the support 10 and the pressing cover 34 to provide an elastic return force for the pressing cover 34 to extend relative to the support 10.

[0182] Further, in the present embodiment, the power adapter 100 further comprises a limiting rod 70 connected between the support 10 and the transmission portion 40. The limiting rod 70 is used to position the movement state of the transmission portion 40.

[0183] Specifically, one end of the limiting rod 70 is rotatably connected to the first housing 101, and the other end of the limiting rod 70 is slidably connected to the connecting block 432 of the rack 43. The one end of the limiting rod 70 is positioned and matched with the sliding position of the connecting block 432. When the plug 20 extends relative to the support 10, the one end of the limiting rod 70 is fixed at a first preset position of the connecting block 432, so that the plug 20 remains in the extended state relative to the support 10. When the plug 20 retracts relative to the support 10, the one end of the limiting rod 70 is fixed at a second preset position of the connecting block 432, so that the plug 20 remains in the retracted state relative to the support 10.

[0184] As an implementation, the connecting protrusion 432 is provided with a curved sliding groove 434, which has a first clamping end 4341 and a second clamping end 4342 opposite to the first clamping end 4341. The sliding groove between the first clamping end 4341 and the second clamping end 4342 extends along a curve. The first clamping end 4341 and the second clamping end 4342 are opposite in the sliding direction of the pressing cover 34. The first clamping end 4341 is away from the pressing cover 34 relative to the second clamping end 4342. One end of the limiting rod 70 is provided with a limiting rotating shaft rotatingly connected to the first shell 101, and the other end of the limiting rod 70 is provided with a limiting sliding block 720. The limiting sliding block 720 extends in parallel with the limiting rotating shaft. The limiting sliding block 720 is in sliding fit with the curved sliding groove 434. When the limiting sliding block 720 slides to the first clamping end 4341, the action force on the pressing cover 34 is removed, the rack 43 is subjected to the elastic action force of the elastic restoring member 80 and the limiting action force of the limiting sliding block 720, so that the rack 43 keeps in a static state away from the fixed baffle 1018, i.e., the pressing cover 34 keeps in a static state of extending relative to the support 10. When the limiting sliding block 720 slides to the second clamping end 4342, the action force on the pressing cover 34 is removed, the rack 43 is subjected to the elastic action force of the elastic restoring member 80 and the limiting action force of the limiting sliding block 720, so that the rack 43 keeps in a static state close to the fixed baffle 1018, i.e., the pressing cover 34 keeps in a static state of retracting relative to the support 10.

[0185] Optionally, the first clamping end 4341 and the second clamping end 4342 are both "V"-shaped grooves, so that the limiting sliding block 720 sliding to the first clamping end 4341 or the second clamping end 4342 can slide-limit the rack 43.

The rotation range of the moving part 30 can be smaller than the rotation range of the prong 20, or can be greater than the rotation range of the prong 20, or can be equal to the rotation range of the prong 20. The rotation speed of the moving part 30 can be smaller than the rotation speed of the prong 20, or can be greater than the rotation speed of the prong 20, or can be equal to the rotation speed of the prong 20.

The first strip-shaped groove and the second strip-shaped groove jointly form a rotating groove 353 of the disc 351. The rotating groove 353 is arranged on the first side face 15 or the second side face 16, so as to facilitate the user to rotate the knob 35 by touching the side of the power adapter 100, thereby achieving the effect of being convenient, fast and labor-saving.

[0191] Two sides of the disc 351 with larger area are perpendicular to the rotating shaft 352. The axis of the rotating shaft 352 is parallel to the thickness direction of the bracket 10, so that the thickness direction of the disc 351 is parallel to the thickness direction of the bracket 10, and the user can slide and touch along the side of the bracket 10 to rotate the disc 351.

[0192] Optionally, the circumferential surface of the wheel disc 351 is provided with a plurality of sawteeth in wavy curve. The plurality of sawteeth are equidistantly arranged along the circumference of the wheel disc 351, so as to facilitate the user to rotate the knob 35. The wheel disc 351 is provided with the plurality of sawteeth, so that the wheel disc 351 can form a gear, to facilitate the transmission of the rotation torque of the wheel disc 351 to the transmission part 40.

[0193] In the embodiment, the transmission part 40 is provided with a first gear 441 engaged with the wheel disc 351 and rotationally connected with the bracket 10, a reversing gear 45 engaged with the first gear 441 and rotationally connected with the bracket 10, and a second gear 442 engaged with the reversing gear 45 and fixedly connected with the rotating shaft 21, the second gear 442 being coaxially arranged with the rotating shaft 21. The first gear 441 forms a gear connected with the first end of the knob 35, and the second gear 442 forms a gear fixedly connected with the last end of the rotating shaft 21. The wheel disc 351 drives the first gear 441 to rotate, the first gear 441 drives the reversing gear 45 and the second gear 442 to rotate, and finally controls the prong 20 to extend or flip relative to the bracket 10.

[0197] It can be understood that, by using the wheel disc 351 with the outer diameter larger than the outer diameter of the first gear 441, a larger transmission ratio can be achieved, so that the knob 35 can drive the prong 20 to flip and extend relative to the bracket 10 after a small amplitude of rotation.

[0198] Of course, in other embodiments, a third gear 443 or more gears in turn meshing can also be provided between the first gear 441 and the reversing gear 45 to increase the transmission effect of the transmission part 40 to meet more use requirements.
