Detailed Description

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

Referring to fig. 1 and 2, the present application provides a power adapter 100, where the power adapter 100 includes a bracket 10, a pin 20 rotatably connected to the bracket 10, and a moving portion 30 movably connected to the bracket 10, and the pin 20 can move with the moving portion 30 relative to the bracket 10 and can be protruded or retracted from the bracket 10 in a reversible manner. . It can be appreciated that the power adapter 100 is plugged into a power socket by using the pins 20, so that the power adapter 100 can obtain electric energy, and thus the electric energy can be conveniently transferred to electronic devices such as a mobile phone, a smart watch, a notebook computer, a tablet computer, a smart earphone and the like. The pins 20 of the power adapter 100 may be pins of various standards such as national standard, or euro standard, or american standard, or english standard, or australia standard, or japanese standard, or korean standard.

The moving part 30 is arranged through the support 10, the pin 20 is rotatably connected to the support 10, and the moving part 30 is moved, so that the pin 20 can be overturned to extend or retract in the support 10 along with the movement of the moving part 30, namely, the pin 20 is not required to be contacted, the extension and retraction of the pin 20 are realized, and the power adapter 100 is convenient and quick to use, labor-saving and safe.

In this embodiment, the power adapter 100 further includes a housing 90, the stand 10 is fixed in the housing 90, and the housing 90 protects the stand 10 firmly and increases the appearance performance of the power adapter 100. The housing 90 is provided with an inner cavity 99 and a through slot 91 communicating with said inner cavity 99. The pins 20 are reversibly extendable or retractable from the through slots 91 relative to the housing 90. I.e. the pins 20 are pivotally connected to the bracket 10 directly opposite the through slots 91. The moving part 30 is movably coupled to the bracket 10 through the housing 90. The moving part 30 is at least partially exposed out of the housing 90, so that the moving part 30 receives a manipulation force of a user, and the moving part 30 can move relative to the bracket 10 and the housing 90.

The bracket 10 is accommodated in the inner cavity 99 and is provided with a boss 109 matched with the through groove 91, the boss 109 is provided with an abutting surface 108 far away from the inner cavity 99, and the abutting surface 108 is inwards concave towards the inner cavity 99 to form the accommodating groove 18. When the pins 20 extend relative to the bracket 10 and the housing 90, the pins 20 are rotatably connected to the end portions of the bracket 10 and are positioned in the receiving grooves 18, and the other end portions are positioned outside the receiving grooves 18. When the pins 20 are contracted relative to the bracket 10 and the housing 90, the pins 20 are completely accommodated in the accommodating grooves 18, so that the pins 20 are hidden and protected, and the size of the power adapter 100 is reduced and the power adapter is convenient to carry. When the pin 20 extends out of the support 10 and the housing 90, the portion of the pin 20 protruding from the contact surface 108 may be plugged into a power socket, and the contact surface 108 abuts against the power socket, so as to avoid the contact between the housing 90 and the power socket. The housing 90 protects the stand 10. The housing 90 may also house a circuit board of electrical connection pins 20 therein for the power adapter 100 to receive and process electrical current.

Optionally, the abutment surface 108 of the boss 109 is flush with the surface of the housing 90 to ensure the flatness of the appearance of the power adapter 100. The abutment surface 108 allows for some assembly discontinuity with the surface of the housing 90, in order to ensure that the abutment surface 108 always preferentially contacts the surface of the housing 90 with the power outlet, the abutment surface 108 protrudes slightly beyond the outer surface of the housing 90.

Optionally, the abutment surface 108 of the boss 109 protrudes relative to the surface of the housing 90, that is, the end of the boss 109 protrudes relative to the surface of the housing 90, so that when the pin 20 is plugged into the power socket, a certain distance exists between the housing 90 and the power socket, so as to ensure the safety of the housing 90.

It will be appreciated that the power adapter 100 employs pins 20 that can be flipped out or retracted, in order to ensure that the pins 20 can be flipped over from time to time, making the structural components that carry the pins 20 for rotational connection more resistant to fatigue. The pin 20 needs to obtain electric energy under the condition that the power supply base is plugged in, so the pin 20 is often faced with the condition that the high-voltage circuit is shorted to generate arc burning, and therefore, in order to ensure the safety of the power adapter 100, the fireproof and anti-burning requirements on structural components for carrying and connecting the pin 20 are high. Obviously, in the embodiment of the application, the support 10 bears the pin 20, the support 10 isolates the plug 20 from the shell 90, and the support 10 has better insulation protection performance, better wear-resisting compression resistance and better fireproof combustion resistance compared with the shell 90, so that the safety of the power adapter 100 can be ensured, and the service life of the power adapter 100 is prolonged. The pins 20 are rotatably connected to the bracket 10, so that the plugging of the shell 90 with the power supply seat can be avoided, the scraping of the shell 90 is avoided, the damage of the shell 90 is avoided, and the appearance performance of the power adapter 100 is ensured.

Specifically, the housing 90 has a first end 92, a second end 93 opposite the first end 92, and a peripheral portion 94 disposed between the first end 92 and the second end 93. The through slot 91 is disposed adjacent the first end 92 at the peripheral side 94. The first end 92 is provided with an insertion hole 95 communicating with the cavity 99 and the through groove 91. The bracket 10 can be inserted into the inner cavity 99 through the insertion hole 95, and the boss 109 is in limit fit with the through groove 91. It will be appreciated that the inner peripheral side wall of the interior cavity 99 is in clearance fit with the outer peripheral side wall of the stent 10 so that the stent 10 can be secured within the interior cavity 99 after insertion into the interior cavity 99 through the insertion hole 95. The end of the through groove 91 far away from the insertion hole 95 is provided with a resisting wall, and the resisting wall can limit the boss 109, so that the insertion of the bracket 10 into the inner cavity 99 is limited, and the bracket 10 is prevented from being excessively retracted into the housing 90.

Optionally, the peripheral side portion 94 has a front surface 941 and a back surface 942 opposite the front surface 941, and a side surface 943 connected between the front surface 941 and the back surface 942. The through groove 91 is opened at the front surface 941.

In the present embodiment, the stand 10 has a front surface 11, a rear surface 12 opposed to the front surface 11, a first end surface 13 and a second end surface 14 connected between the front surface 11 and the rear surface 12 and disposed opposite to each other, and a first side surface 15 and a second side surface 16 connected between the front surface 11 and the rear surface 12 and disposed opposite to each other. A boss 109 is provided at the front face 11 adjacent the first end face 13. The pins 20 extend from the front face 11 or retract into the holder 10. The first end surface 13 and the second end surface 14 may be located at front and rear ends of the bracket 10, respectively, and the first side surface 15 and the second side surface 16 may be located at left and right sides of the bracket 10. After the bracket 10 is secured to the interior cavity 99, the first end face 13 is adjacent the first end 92 of the housing 90 and the second end face 14 is received within the interior cavity 99.

In this embodiment, when the prongs 20 are in an extended state relative to the bracket 10, the ends of the prongs 20 protrude relative to the front surface 941. The end of the pin 20 is provided with a metal conductor so that the pin 20 is conducted with a power electrode in the power socket, and the abutting surface 108 abuts against the power socket. When the pins 20 are in a contracted state relative to the bracket 10, the pins 20 are accommodated in the accommodating grooves 18, so that the whole power adapter 100 is rectangular, the power adapter 100 can be conveniently accommodated and carried, the pins 20 can be effectively protected by the bracket 10, and the safety is ensured.

Specifically, the pin 20 is provided with a rotation shaft 21 and two pins 22 fixed to the rotation shaft 21. The longitudinal direction of the pin 22 is perpendicular to the longitudinal direction of the rotation shaft 21. The center axis of the pin 22 intersects with the center axis of the rotary shaft 21. The two pins 22 are juxtaposed in the axial direction of the rotation shaft 21. The rotation shaft 21 is always located in the accommodation groove 18. The rotational shaft 21 is adjacent the receiving recess 18 away from the first end face 13 such that the end of the pin 22 remote from the rotational shaft 21 can be flipped out of the receiving recess 18. When the pins 20 are in a contracted state relative to the rack 10, the bottom walls of the accommodating grooves 18 limit the pins 20 so as to prevent the pins 20 from being too contracted into the rack 10. When the pin 20 is in the state of extending out relative to the bracket 10, the side wall of the accommodating groove 18 adjacent to the rotating shaft 21 limits the pin 20, so as to prevent the pin 20 from turning over too much angle relative to the bracket 10, which is not beneficial to the plug 20 and the power supply socket. The rotating shaft 21 may be provided with an insulator coating one end of the pin 22, and the rotating shaft 21 separates the two pins 22 to avoid shorting of the two pins 22. The pin 22 is a metal piece to enable the pin 20 to draw current.

The abutment surface 108 is provided with two opposite receiving grooves 18, the rotation shaft 21 passes through the two receiving grooves 18, and the two pin posts 22 are respectively telescopically engaged with the two receiving grooves 18 in a reversible manner. The two pin columns 22 are respectively accommodated by the two accommodating grooves 18, so that the stability of the bracket 10 is increased, the two pin columns 22 can be effectively isolated, and the pin columns 22 are prevented from being shorted.

In this embodiment, the bracket 10 is provided with a housing cavity 17, and the housing cavity 17 is used for housing devices such as a circuit board, a power chip, a power transformer module, and the like. One end of the pin 20 rotating connection bracket 10 is provided with a part to be accommodated in the accommodating cavity 17, so that the pin 20 can be electrically connected with devices such as a circuit board, a power chip, a power transformation module and the like. Alternatively, the bracket 10 includes a first housing 101 and a second housing 102 that covers the first housing 101, the boss 109 is disposed on a side of the first housing 101 facing away from the second housing 102, and the rotation shaft 21 is rotatably connected between the first housing 101 and the second housing 102. The front surface 11 is formed on a surface of the first housing 101 facing away from the second housing 102, and the back surface 12 is formed on a surface of the second housing 102 facing away from the first housing 101. The rotation shaft 21 is clamped by the first housing 101 and the second housing 102, so that the rotation shaft 21 rotates smoothly and stably relative to the bracket 10.

Specifically, a bearing boss 103 is formed in the first housing 101 facing the second housing 102 and corresponding to the receiving groove 18, and a bearing boss 104 in butt fit with the bearing boss 103 is provided in the second housing 102 facing the first housing 101. The bearing boss 103 is provided with a first U-shaped groove 105, and the bearing boss 104 is provided with a second U-shaped groove 106. 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 turned over relative to the bracket 10. The first U-shaped groove 105 communicates the accommodating chamber 17 and the accommodating groove 18. Two first U-shaped grooves 105 are provided on both side walls of the bearing boss 103, respectively, so that the rotation shaft 21 passes through the receiving groove 105 via the first U-shaped grooves 105, and the pin posts 22 are fixed to portions of the rotation shaft 21 passing through the receiving groove 105. The second housing 102 is provided with four bearing protrusions 104 corresponding to four second U-shaped grooves 106, so as to increase structural stability of the rotating shaft 21 and the bracket 10, ensure smooth rotation of the rotating shaft 21 relative to the bracket 10, and effectively isolate the two pin columns 22.

In this embodiment, the power adapter 100 further includes two pin spring pieces 60, and the two pin spring pieces 60 are electrically connected to the two pin posts 22, respectively. The pin 22 is provided with a conductive contact end 23 far away from the rotation shaft 21, when the pin 20 is turned over to extend out relative to the bracket 10, the conductive contact end 23 elastically abuts against the pin elastic sheet 60, and when the pin 20 is turned over to be in a contracted state relative to the bracket 10, the conductive contact end 23 is separated from the pin elastic sheet 60.

Specifically, the pin dome 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 bracket of the second housing 102. Bent end 62 is opposite leg 22 of pin 20. The curved end 62 is curved along a curve. The curved end 62 has elastic deformation properties. When the pin 20 is turned over to extend out of the support 10, the conductive contact end 23 rotates to contact with the curved end 62, so that the curved end 62 deforms, the curved end 62 applies elastic interference force to the conductive contact end 23, so that the pin 22 contacts with the pin spring 60 more tightly, and a damping force exists in the turning process of the pin 22, namely, a damping force exists in the turning process of the pin 20 relative to the support 10, so that the turning impact acting force of the pin 20 on the support 10 is reduced. When the pins 20 are turned to a contracted state with respect to the holder 10, the conductive contact terminals 23 are rotated to a separated state from the bent terminals 62, and the bent terminals 62 return to a natural extended state.

More specifically, the first housing 101 is further provided with a spring clip slot 107 at one side of the bearing boss 103, the pin spring 60 is provided with a conducting leg 63 that is clipped into the spring clip slot 107, and an end of the rotating shaft 21 extends into the spring clip slot 107 and abuts against the conducting leg 63, so that the pin 22 is kept in a conducting state with the conducting leg 63 via the rotating shaft 21. The rotation shaft 21 is provided with shaft conductors respectively contacting the two pins 22, and the ends of the shaft conductors extend into the spring clip grooves 107 and contact the conductive legs 63. The portions of the rotating shaft 21 where both axial conductors are connected to the pin posts 22 are covered with an insulator to prevent short circuits. The spring clip groove 107 stabilizes the conductive leg 63, so that the pin spring 60 can still keep effectively contacting with the pin 20 after the pin 20 turns over with respect to the bracket 10 for a plurality of times, thereby increasing the stability of the pin spring 60 and the effective conductive performance with the pin 20, and increasing the service life of the power adapter 100.

In this embodiment, referring to fig. 3 and 4, the moving portion 30 is movably disposed on the bracket 10. The moving portion 30 may be disposed on the first end surface 13 or the second end surface 14. The moving part 30 may move linearly on the support 10, or may rotate on the support 10, or may move linearly and rotationally on the support 10. The moving part 30 may move by a manual driving force of a user. The moving part 30 is separated from the accommodating groove 18, so that the moving part 30 is prevented from approaching the pin 20, and a user can operate the moving part 30 on the support 10 at a position far away from the pin 20, and the pin 20 can extend or retract relative to the support 10, so that safety is ensured.

Referring to fig. 5, 6 and 7, it can be appreciated that the power adapter 100 of the present application further includes a transmission portion 40 accommodated in the cavity 99, and the transmission portion 40 is connected to the moving portion 30 and the pin 20, so as to convert the movement torque of the moving portion 30 into a rotational torque and transmit the rotational torque to the pin 20, so that the pin 20 is turned relative to the housing 90. That is, the moving part 30 moves relative to the bracket 10, so that the moving part 30 drives the pin 20 to extend or retract relative to the bracket 10.

The moving part 30 is slidably disposed on the bracket 10 and located outside the receiving groove 18, and the transmission part 40 converts the linear sliding torque of the moving part 30 into a rotational torque and transmits the rotational torque to the rotational shaft 21 of the pin 20. The moving part 30 is slidable in a straight line with respect to the bracket 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 to the rotation shaft 21 such that the transmission part 40 can transmit rotation torque to the rotation shaft 21 such that the rotation shaft 21 rotates relative to the bracket 10.

In the present embodiment, the moving portion 30 is provided with a pressing cover 34, and the pressing cover 34 is slidably provided at an end portion of the bracket 10. The pressing cover 34 is linearly slidable with respect to the housing 90 upon receiving a pressing force from a user. The pressing cover 34 transmits the linear sliding torque to the transmission portion 40, and the transmission portion 40 converts the linear sliding torque into rotational torque and transmits it to the rotating shaft 21.

Alternatively, the pressing cover 34 is slidably disposed 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 face 13 or the second end face 14.

Optionally, the pressing cover 34 completely covers the first end face 13 or the second end face 14.

Specifically, referring to fig. 5, 6 and 7, the bracket 10 is provided with a sliding guide hole 171 extending into the accommodating cavity 17 at the first end surface 13. The pressing cover 34 includes a pressing cover 341 and a sliding protrusion 342 provided to the pressing cover 341. The sliding protrusion 342 is slidably engaged with the sliding guide hole 171. The pressing cover 341 may cover the first end face 13. The pressing cover 341 has a connecting portion 323 for connecting the transmission portion 40 to the receiving groove 18. When the pressing cover 34 is pressed to retract toward the bracket 10, the pressing cover 34 transmits sliding torque to the transmission part 40, and the transmission part 40 drives the rotating shaft 21 to rotate and drives the pins 20 to turn to an extended state relative to the housing 90. When the pressing cover 34 returns to the extended state relative to the bracket 10, the transmission part 40 drives the pin 20 to flip to the retracted state relative to the housing 90.

Optionally, the connecting portion 323 is provided with a plug rod 3231. The insertion rod 3231 is inserted into the transmission portion 40 to transmit the sliding moment of the pressing cap 34 to the transmission portion 40.

In the present embodiment, the transmission portion 40 includes a rack gear 43 fixedly connected to the pressing cover 34 and a gear 44 meshed with the rack gear 43 and fixed to the rotation shaft 21. The gear 44 is disposed coaxially with the rotation shaft 21. The rack 43 is slidably fitted to the first housing 101. The end of the rack 43 is fixedly connected to 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 rotation shaft 21 and is located between the two pins 22.

Optionally, the end of the rack 43 is provided with a connection protrusion 432, and the connection protrusion 432 is provided with a connection insertion hole 433 that is inserted into the insertion rod 3231, so that the insertion rod 3231 is firmly connected to the pressing cover 34.

Optionally, the first housing 101 is provided with a rack runner 1019, and the rack runner 1019 slidingly guides the rack 43.

Further, in the present embodiment, the power adapter 100 further includes an elastic restoring member 80, where the elastic restoring member 80 is elastically connected between the bracket 10 and the rack 43, and the elastic restoring member 80 is configured to provide an elastic restoring force for restoring the pressing cover 34 to an extended position relative to the bracket 10.

The first housing 101 is provided with a fixed baffle 1018 at an end of the rack runner 1019 remote from the pressing cover 34. One end of the elastic restoring member 80 is fixedly abutted against the fixing plate 1018, and the other end is fixedly abutted against one end of the rack 43 away from the connecting portion 323. When the pressing cover 34 is pressed to contract against the bracket 10, the rack gear 43 compresses the elastic return 80, so that the elastic return 80 is elastically deformed. When the pressing force of the pressing cover 34 is removed, the elastic member restoring member 60 is restored toward the natural extended state, so that the rack gear 43 pushes the pressing cover 34 to protrude with respect to the housing 90. Of course, in other embodiments, the elastic restoring member 80 may be connected between the bracket 10 and the pressing cover 34 to provide an elastic restoring force of the pressing cover 34 extending relative to the bracket 10.

Further, in the present embodiment, the power adapter 100 further includes a stopper rod 70 connected to the bracket 10 and the transmission part 40. The stop lever 70 is used to position the motion state of the transmission part 40.

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 connection lug 432 of the rack 43. One end of the stop lever 70 is utilized to engage the sliding position of the connection tab 432. After the pin 20 protrudes with respect to the bracket 10, one end of the stopper rod 70 is fixed at a first predetermined position of the connection protrusion 432, so that the pin 20 maintains the protruding state with respect to the bracket 10. When the pin 20 is contracted relative to the bracket 10, one end of the stopper 70 is fixed at the second preset position of the connection protrusion 432, so that the pin 20 maintains the contracted state relative to the bracket 10.

As an embodiment, the connection protrusion 432 is provided with a limiting chute 434, and the limiting chute 434 has a first retaining end 4341 and a second retaining end 4342 opposite to the first retaining end 4341. The sliding groove between the first retaining end 4341 and the second retaining end 4342 extends along a curve. The first retaining end 4341 is opposite to the second retaining end in the sliding direction of the pressing cover 34. The first retaining end 4341 is distal to the pressing cap 34 relative to the second retaining end 4342. One end of the limiting rod 70 is provided with a limiting rotating shaft which is rotationally connected with the first shell 101, and the other end of the limiting rod 70 is provided with a limiting sliding block 72. The limit slider 72 extends parallel to the limit rotation axis. The limit slider 72 is in sliding engagement with the limit chute 434. When the limit slider 72 slides to the first retaining end 4341, the force applied to the pressing cover 34 is removed, the rack 43 is elastically biased by the elastic restoring member 80, and the limit force of the limit slider 72, so that the rack 43 is kept away from the stationary state of the fixing plate 1018, i.e., the pressing cover 34 is kept in a stationary state protruding relative to the bracket 10. When the limit slider 72 slides to the second retaining end 4342, the force applied to the pressing cover 34 is removed, and the rack 43 is elastically biased by the elastic restoring member 80 and the limit force of the limit slider 72, so that the rack 43 is kept in a stationary state close to the fixing plate 1018, i.e., the pressing cover 34 is kept in a stationary state contracted with respect to the bracket 10.

Optionally, the first retaining end 4341 and the second retaining end 4342 are both V-shaped, so that the limiting slider 72 slides to the first retaining end 4341 or the second retaining end 4342 to limit the sliding movement of the rack 43.

Referring to fig. 8, the present application further provides an electronic device assembly 200, where the electronic device assembly 200 includes the power adapter 100 and the electronic device 300.
