Detailed Description

As used herein, a "power adapter" may be an electric energy conversion device that transmits electric energy to an electronic device, and the power adapter may have devices such as a transformer, an inductor, a capacitor, a control chip, and a circuit board, which are mainly used to convert a high voltage into a low voltage required for the electronic device to be able to operate, so that the electronic device, such as a mobile phone, a tablet computer, a smart watch, smart glasses, and a wireless headset, can operate normally. Taking a mobile phone as an example, the power adapter can convert alternating current on the socket into direct current to charge a battery of the mobile phone, so that the mobile phone can be normally used. Of course, the power adapter may also directly transmit power to operate the electronic device, and is not limited to charging the electronic device.

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1 to 4, fig. 1 is a front view of a power adapter 10 according to an embodiment of the present disclosure, fig. 2 is another front view of the power adapter 10 in fig. 1, fig. 3 is a top view of the power adapter 10 in fig. 1, and fig. 4 is a top view of the power adapter 10 in fig. 2.

The power adapter 10 may be used to transfer power to the electronic device for proper operation of the electronic device. For example, the power adapter 10 may be a charging plug of a mobile phone, which can be electrically connected to the mobile phone through a patch cord, so as to convert the power of the socket and transmit the converted power to the mobile phone. As shown in fig. 1 to 4, the power adapter 10 may include: a fixing seat 100, a pin 200 and a rotating mechanism 300. The plug-in pin 200 and the rotating mechanism 300 can be both disposed on the fixing base 100, and the plug-in pin 200 can rotate relative to the fixing base 100, and the rotating mechanism 300 can rotate relative to the fixing base 100. Meanwhile, the pins 200 are also connected to the rotating mechanism 300 and linked with the rotating mechanism 300. In this embodiment, a user can change the state of the pins 200 by adjusting the position of the rotating mechanism 300, so that when the power adapter 10 needs to be used, the pins 200 can be rotated to be electrically connected with the socket, and when the power adapter 10 does not need to be used, the pins 200 can be rotated to be electrically disconnected with the socket. Thus, when a user without the ability to perform an autonomous action obtains the placed power adapter 10, the former cannot directly plug the plug pins 200 into the socket, which can reduce the safety risk of the user using the power adapter 10.

Specifically, when the rotating mechanism 300 rotates to the first position, the pin 200 may be moved to a first predetermined state, and the pin 200 may be plugged into the socket to be electrically connected in the first predetermined state. When the rotating mechanism 300 rotates to the second position, the plug 200 can be moved to the second predetermined state, and the plug 200 cannot be plugged into the socket to be electrically connected in the second predetermined state. In this way, the user can adjust the rotating mechanism 300 to the second position, so that the plug pins 200 can be placed in the second preset state, thereby reducing the safety risk after the user acquires the power adapter 10. As an example, the prongs 200 shown in fig. 1 and 3 may be in a first predetermined state and the rotation mechanism 300 shown may be in a first position. The prongs 200 shown in fig. 2 and 4 may be in a second predetermined state and the rotation mechanism 300 shown may be in a second position.

Further, since the number of the pins 200 is two, the rotating mechanism 300 may be disposed on two opposite sides of the fixing base 100, such that the rotating mechanism 300 on one side of the fixing base 100 may be linked with one pin 200, and the rotating mechanism 300 on the other opposite side may be linked with the other pin 200. So, power adapter 10 only can realize the electricity even with the socket grafting when the slewing mechanism 300 of relative both sides all is in the first position, and only need arbitrary slewing mechanism 300 be in the second position, can make power adapter 10 can not realize the electricity even with the socket grafting, and the linkage mode independent mutually can further reduce the safety risk that exists after the user takes power adapter 10 like this.

Alternatively, the fixing base 100 may be provided with a rotating mechanism 300 on only one side, and the state of the pin 200 may be changed by the linkage of a single rotating mechanism 300 and one pin 200. In this way, the security risk of the user after taking the power adapter 10 can still be reduced.

Referring to fig. 5 to 6, fig. 5 is a schematic structural diagram of a power adapter 10 according to an embodiment of the present application, and fig. 6 is another schematic structural diagram of the power adapter 10 in fig. 5.

The rotating mechanism 300 may receive the pins 200 in addition to the pins 200 in order to protect the pins 200. As shown in fig. 5 to 6, when the rotating mechanism 300 rotates to the first position, the pin 200 may be exposed to the outside and is in a first predetermined state, so that the pin 200 is plugged into a socket to be electrically connected. When the rotating mechanism 300 rotates to the second position, the pin 200 is received by the rotating mechanism 300 and is in the second preset state. Thus, the rotating mechanism 300 can be linked with the pins 200 and can also protect the pins 200, and when the rotating mechanism 300 accommodates the pins 200, a user can take the power adapter 10 and cannot directly plug the power adapter 10 into a socket, so that the safety risk existing after the user obtains the power adapter can be reduced. As an example, the prongs 200 shown in fig. 5 may be in a first predetermined state and the rotation mechanism 300 may be in a first position. Fig. 6 shows the rotation mechanism 300 in a second position and the pins 200 (shown in phantom) in a second predetermined position.

In this embodiment, the pin 200 is coupled to the base 100 in the same manner regardless of whether the rotating mechanism 300 is used to accommodate the pin 200. The aforementioned rotating mechanism 300 does not need to accommodate the prong 200, and it is well within the skill of the art to adapt the shape and size of the rotating mechanism 300 to the accommodation of the prong 200 by the rotating mechanism 300. Therefore, the following description will be given of a specific configuration of the power adapter 10, taking as an example only the case where the rotating mechanism 300 can accommodate the pins 200.

Referring to fig. 7 to 8, fig. 7 is an exploded schematic view of the fixing base 100 in fig. 5, and fig. 8 is a schematic view of the seat body 110 in fig. 7.

The holder 100 may be used to mount a circuit board of the power adapter 10 in addition to the pins 200 and the rotation mechanism 300. As shown in fig. 7, the holder 100 may include: a housing 110 and a case 120. The base 110 may be connected to the box 120, and the base and the box may jointly enclose to form the accommodating cavity 101, so as to install the circuit board of the power adapter 10 by using the accommodating cavity 101. Meanwhile, the base 110 can be connected with the pins 200 and the rotating mechanism 300, and both the pins 200 and the rotating mechanism 300 can rotate relative to the base 110. In addition, the base 110 and the box 120 may be made of plastic, and both may be formed by injection molding. Optionally, the fixing base 100 may also only include the seat body 110, and the box body 120 may be an independent structural component from the fixing base 100, and only the box body 120 can be connected to the seat body 110 and jointly surround the accommodating cavity 101 for mounting the circuit board, which is not limited in this embodiment.

The housing 110 may be used to connect the pins 200 and the rotating mechanism 300 to achieve the movement of the pins 200 and the rotating mechanism 300. As shown in fig. 7 to 8, the holder body 110 may include: a main body part 111, a first shielding part 112, and a second shielding part 113. The main body 111 can be connected to the pin 200 and the rotation mechanism 300, and both the first blocking portion 112 and the second blocking portion 113 can be connected to the main body 111 and can be used for blocking the rotation mechanism 300 on the main body 111. Alternatively, the first shielding portion 112 and the second shielding portion 113 can be omitted, and the seat body 110 can include only the main body portion 111.

Referring to fig. 9 to 10 in conjunction with fig. 8, fig. 9 is a schematic structural view of the main body 111 in fig. 8, and fig. 10 is a schematic structural view of the main body 111 in fig. 8 from another perspective.

As shown in fig. 8 to 9, the body portion 111 may have a top surface 1101, a bottom surface 1102, a first side surface 1103, a second side surface 1104, a third side surface 1105, and a fourth side surface 1106. Wherein the top surface 1101 can be exposed outside the receiving cavity 101 and is disposed opposite to the bottom surface 1102. The first side surface 1103, the second side surface 1104, the third side surface 1105, and the fourth side surface 1106 may each connect the top surface 1101 and the bottom surface 1102, respectively, and the first side surface 1103 may be disposed opposite to the second side surface 1104, and the third side surface 1105 may be disposed opposite to the fourth side surface 1106. Meanwhile, the top surface 1101 may be used to mount the pin 200, and the bottom surface 1102, the first side surface 1103, the second side surface 1104, the third side surface 1105, and the fourth side surface 1106 may all be used to mount the rotation mechanism 300. In the present embodiment, the first side surface 1103, the second side surface 1104, the third side surface 1105, and the fourth side surface 1106 may also be disposed perpendicular to the top surface 1101.

Specifically, the main body part 111 may be provided with through holes 11101 penetrating the top and bottom surfaces 1101 and 1102, so that the pins 200 may be inserted not only on the top surface 1101 using the through holes 11101 but also protrude from the bottom surface 1102 at one end thereof using the through holes 11101, thereby being electrically connected with the circuit board within the receiving cavity 101. The bottom surface 1102 is further provided with corresponding first mounting grooves 11102 for mounting a part of the structure of the rotating mechanism 300, so that the end of the pins 200 extending out of the bottom surface 1102 can be connected with the rotating mechanism 300 to realize the linkage of the pins 200 and the rotating mechanism 300. The first side surface 1103 and the second side surface 1104 are both provided with a second mounting groove 11103, and the second mounting groove 11103 can be used for mounting another part of the structure of the rotating mechanism 300, so as to realize the transmission of the rotating mechanism 300. The third side surface 1105 and the fourth side surface 1106 are both provided with a third mounting groove 11104, and the third mounting groove 11104 can also penetrate through the top surface 1101, which can be used for mounting the rest structure of the rotating mechanism 300, so as to realize the rotation of the rotating mechanism 300 relative to the fixed seat 100.

As shown in fig. 8 and 10, the first shielding portion 112 may be disposed on the bottom surface 1102, which may be used to shield the rotating mechanism 300 disposed in the first mounting groove 11102. Meanwhile, the first blocking portion 112 may further be provided with a hole communicating the accommodating cavity 101 and the through hole 11101 to avoid an end of the pin 200 extending out of the bottom surface 1102, so that the pin 200 can be electrically connected to the circuit board in the accommodating cavity 101. The second shielding portion 113 may be disposed in the second mounting groove 11103 and may be used to shield the rotating mechanism 300 disposed in the second mounting groove 11103. Meanwhile, the shape of the second blocking portion 113 can be matched with the second installation groove 11103 to fill the second installation groove 11103, and improve the flatness of the outer surface of the seat body 110. In addition, the number of the second shielding portions 113 may be two, and the two second shielding portions 113 may be respectively located in the second mounting grooves 11103 formed on the first side surface 1103 and the second side surface 1104. In the present embodiment, the first and second shade portions 112 and 113 can each be locked to the body portion 111 by screws.

Referring to fig. 7, the box 120 may be a hollow plate structure, and one side of the box 120 has an opening communicating with the outside, and the main body 111 covers the opening of the box 120 and surrounds the box 120 to form the accommodating chamber 101. Meanwhile, the box body 120 may also be disposed around and attached to a side surface of the main body 111, and may be used to shield the first shielding part 112 and the second shielding part 113 on the main body 111. In addition, box body 120 may also be provided with a notch communicating with accommodating chamber 101, so that the charging wire may be electrically connected to the circuit board in accommodating chamber 101 from the notch. It is understood that the aforementioned "side surfaces" may include, but are not limited to, the first side surface 1103, the second side surface 1104, the third side surface 1105, and the fourth side surface 1106. Optionally, the shape of the box 120 is not limited to be a plate-shaped structure, and the specific shape of the box 120 may also be adjusted according to design requirements, as long as the box 120 and the main body 111 can jointly enclose the accommodating cavity 101.

Referring to fig. 11 to 13 in conjunction with fig. 10, fig. 11 is a schematic structural view of the pin 200 in fig. 5, fig. 12 is a schematic structural view of the connection structure between the holder 100 and the pin 200 in fig. 5, and fig. 13 is a schematic structural view of a cross section of the holder 100 and the pin 200 in fig. 12 along v-v.

The pins 200 may be plugged into a receptacle to electrically connect the power adapter 10 to the receptacle. As shown in fig. 10 to 13, the pin 200 may include: a conductive member 210 and a rotational member 220. The conductive member 210 may be inserted into the main body 111, and the conductive member 210 may be electrically connected to the circuit board in the accommodating cavity 101. The rotating element 220 may be disposed around an outer surface of the conductive element 210, and may be configured to be connected to the rotating mechanism 300, and may be driven by the rotating mechanism 300 to rotate relative to the main body 111 in an axial direction perpendicular to the top surface 1101, so as to drive the conductive element 210 to rotate, so that the conductive element 210 may be switched between a first preset state and a second preset state. In this embodiment, the conductive element 210 may be made of a conductive metal, and the rotating element 220 may be made of a plastic, so that the pin 200 may be integrally formed through a metal insert molding process. Alternatively, the pin 200 may only include the conductive member 210, and the rotating member 220 may be a part of the rotating mechanism 300 for rotating the conductive member 210.

The conductive component 210 may be disposed in the through hole 11101, and one end of the conductive component 210 may protrude from the top surface 1101 for being plugged into a socket, and the other opposite end may protrude from the bottom surface 1102 and be electrically connected to the circuit board in the receiving cavity 101 through the hole of the first shielding portion 112. Meanwhile, one end of the conductive member 210 protruding from the top surface 1101 may be a sheet structure to match with the shape of the insertion hole on the socket, so as to realize the insertion of the conductive member 210 and the socket. The end of the conductive member 210 protruding from the bottom surface 1102 may be cylindrical to facilitate the conductive member 210 to be electrically connected to the circuit board in the receiving cavity 101. For example, the circuit board and the conductive element 210 may be electrically connected through a metal dome, the metal dome may clamp an end of the conductive element 210 protruding from the bottom surface 1102 and elastically abut against an end of the conductive element 210 protruding from the bottom surface 1102, and the cylindrical design of the end of the conductive element 210 electrically connected to the circuit board may improve the contact reliability of the conductive element 210 with the metal dome during the rotation process.

As shown in fig. 12 to 13, the rotation member 220 may include: a sleeve portion 221 and a gear portion 222. The sleeve portion 221 may be located in the through hole 11101 and disposed around one end of the conductive element 210 in a sheet structure, and the sleeve portion 221 may have a shape matching the through hole 11101, and may have opposite ends flush with the top surface 1101 and the bottom surface 1102, respectively, so as to fill a gap between the sheet structure of the conductive element 210 and the inner wall of the through hole 11101. The gear portion 222 may be located on the bottom surface 1102 and connected to an end of the sleeve portion 221 away from the top surface 1101, and the gear portion 222 is further disposed around an end of the conductive member 210 having a cylindrical structure, which may be used for meshing transmission with the rotation mechanism 300, so as to realize linkage of the pins 200 and the rotation mechanism 300. Meanwhile, the rotational axis direction of the gear portion 222 may be parallel to the direction perpendicular to the top surface 1101. In this configuration, when the rotating mechanism 300 starts to rotate, the conductive member 210 can rotate around the direction perpendicular to the top surface 1101 under the driving of the rotating member 220, so as to rotate to the first predetermined state or the second predetermined state.

Referring to fig. 14 to 15, fig. 14 is a schematic view of a partial connection structure between the fixing base 100 and the plug 200 in the first preset state in fig. 12, and fig. 15 is a schematic view of a partial connection structure between the fixing base 100 and the plug 200 in the second preset state in fig. 12.

As shown in fig. 14 to 15, the orthographic projection pattern of the conductive device 210 on the top surface 1101 may have a long side 211 and a short side 212 which are connected, and the top surface 1101 may also have a first side 11011 and a second side 11012 which are connected. When the conductive element 210 is in the first predetermined state, the extending direction of the long side 211 may be parallel to the extending direction of the first side 11011, and the extending direction of the short side 212 may be parallel to the extending direction of the second side 11012. When the conductive element 210 is in the second preset state, the extending direction of the long side 211 may intersect with the extending direction of the first side 11011, and the extending direction of the short side 212 may intersect with the extending direction of the second side 11012. So set up, electrically conductive 210 can have different forms under first preset state and the second preset state for electrically conductive 210 can with the socket assorted first preset state under, peg graft with the socket and realize the electricity and be connected, and with the socket unmatched second preset state under, can't peg graft with the socket and realize the electricity and be connected.

Preferably, when the conductive element 210 is in the second preset state, the extending direction of the long side 211 may be perpendicular to the extending direction of the first side 11011, the extending direction of the short side 212 may be perpendicular to the extending direction of the second side 11012, and the rotation angle of the conductive element 210 with respect to the main body portion 111 may range from 0 to 90 °. By the arrangement, the angle difference between the conductive piece 210 in the second preset state and the first preset state can be increased, and the probability that the conductive piece 210 can still be inserted into the socket due to the fact that the difference is not obvious before and after rotation is reduced.

It is understood that the aforementioned first preset state and second preset state are only one of the alternative embodiments of the present application. For example, when the conductive element 210 is in the first preset state, the extending direction of the long side 211 may be perpendicular to the extending direction of the first side 11011, and the extending direction of the short side 212 may be perpendicular to the extending direction of the second side 11012. When the conductive element 210 is in the second predetermined state, the extending direction of the long side 211 may be parallel to the extending direction of the first side 11011, and the extending direction of the short side 212 may be parallel to the extending direction of the second side 11012. That is, the first preset state and the second preset state may also be adaptively adjusted according to different specifications of the socket and the power adapter 10, and only the plug 200 may be plugged into the socket in the first preset state, and may not be plugged into the socket in the second preset state, which is not limited herein.

As shown in fig. 14 to 15, the number of the pins 200 may be two, i.e., a first pin 201 and a second pin 202, and the first pin 201 and the second pin 202 may be independently switched between a first preset state and a second preset state. The first pin 201 and the second pin 202 may be disposed in parallel, and the connection manner between the first pin 201 and the second pin 202 is the same as that of the pin 200 in the foregoing embodiment, which is not described herein again. In this way, the power adapter 10 can be plugged into the socket to realize electrical connection only when the first pin 201 and the second pin 202 are both in the first preset state, and only when any one of the first pin 201 and the second pin 202 is in the second preset state, the power adapter 10 cannot be plugged into the socket to realize electrical connection. In the case where the rotating mechanism 300 does not accommodate the pins 200, such independent linkage may further reduce the security risk after the user takes the power adapter 10.

Of course, the first pin 201 and the second pin 202 may also rotate synchronously. For example, a gear portion 222 of the first pin 201 and a gear portion 222 of the second pin 202 may be disposed therebetween with synchronizing gears respectively engaged with the two gear portions 222, so that the first pin 201 and the second pin 202 may rotate synchronously and in opposite directions.

As shown in fig. 16 to 17, the rotation mechanism 300 may include: a flip member 310 and a transmission member 320. Wherein, the flip cover assembly 310 can be connected with the main body 111 and can rotate relative to the main body 111. The transmission member 320 is located on the main body 111 and is connected to the flip member 310 and the gear portion 222, respectively, which can be used to realize the linkage of the flip member 310 and the pins 200. In the present embodiment, when the flip member 310 rotates to the first position, the pins 200 can rotate to the first predetermined state under the driving of the transmission member 320. When the flip member 310 rotates to the second position, the pins 200 can rotate to the second predetermined state under the driving of the transmission member 320, and the flip member 310 can further receive the pins 200 in the second predetermined state.

Specifically, the flip member 310 may include: a connector 311 and a flip cover 312. The first end 3111 of the connecting member 311 can be disposed in the third mounting groove 11104, and the connecting member 311 can also be rotatably connected with respect to the main body 111. For example, the main body 111 may be provided with a first rotation shaft 1111 disposed through the first end 3111 so that the connection member 311 can rotate with respect to the main body 111. The second end 3112 of the connecting member 311 can be connected to the flip 312 to drive the flip 312 to rotate relative to the main body 111, and the flip 312 can also rotate relative to the second end 3112 of the connecting member 311. For example, the flip 312 may also be provided with a second rotating shaft 3121 penetrating the second end 3112, so that the flip 312 can rotate relative to the connecting element 311. The flip cover 312 can be driven by the connecting member 311 to rotate relative to the main body 111, and the flip cover 312 can also receive the pins 200 located on the main body 111 after rotating to the corresponding position. For example, the flip cover 312 may be formed with corresponding receiving grooves 3122 for receiving the pins 200. In this embodiment, the rotational axis direction of the connector 311 may be perpendicular to the rotational axis direction of the pin 200. Alternatively, in the case where the pin 200 is not received in the rotating mechanism 300, the rotating shaft direction of the connector 311 may be parallel to the rotating shaft direction of the pin 200.

The transmission assembly 320 can be connected to the connecting member 311, and can be driven by the connecting member 311 to rotate relative to the main body 111, so as to drive the gear portion 222 connected to the transmission assembly 320 to rotate. As shown in fig. 16 and 18, the transmission assembly 320 may include: a first gear set 321 and a second gear set 322. The first gear set 321 may be disposed in the second mounting groove 11103, and the first gear set 321 may be connected to the connecting member 311 and driven by the connecting member 311 to rotate relative to the main body 111. The second gear set 322 may be disposed in the first mounting groove 11102, and the second gear set 322 may further be connected to the first gear set 321 and the gear portion 222 respectively, and may be driven by the first gear set 321 to rotate relative to the main body portion 111, so as to drive the gear portion 222 to rotate.

Specifically, the first gear set 321 may be provided with three gears 3211 engaged in sequence, and all of the three engaged gears 3211 may be disposed in the second mounting groove 11103 and rotate relative to the main body 111. The gear 3211 at the first end of the meshing may be connected to the connecting member 311, and may be driven by the connecting member 311 to rotate relative to the main body 111. For example, one end of the first rotating shaft 1111 may be disposed in the second mounting groove 11103, and the gear 3211 at the head end of the engagement may be sleeved on the first rotating shaft 1111, so that the connecting member 311 may drive the gear 3211 at the head end of the engagement to rotate via the first rotating shaft 1111. Meanwhile, the gear 3211 at the engagement tail end may be coaxially disposed with the second gear set 322, so that the gear 3211 at the engagement tail end may drive the second gear set 322 to rotate, thereby achieving the rotation of the pin 200. In the present embodiment, the rotational axis directions of the three sequentially meshing gears 3211 are all parallel to the rotational axis direction of the connecting member 311.

The second gear set 322 may be provided with a bevel gear 3221 and a dual gear 3222. The bevel gear 3221 and the dual gear 3222 are both disposed in the first mounting groove 11102 and are rotatable relative to the main body 111. Meanwhile, the bevel gear 3221 may be disposed coaxially with the gear 3211 at the engagement tail end, and may be driven by the gear 3211 at the engagement tail end to rotate relative to the main body 111.

For example, the dual gear 3222 may have a large gear and a small gear coaxially disposed, the bevel gear 3221 may be engaged with the small gear of the dual gear 3222, and the gear portion 222 may be engaged with the large gear of the dual gear 3222. In the present embodiment, the total transmission ratio of the first gear set 321, the second gear set 322 and the gear portion 222 may be 1.

Optionally, the first gear set 321 may not be limited to be provided with three gears 3211 that are sequentially engaged, the second gear set 322 may also not be limited to be provided with a bevel gear 3221 and a duplicate gear 3222 that are engaged, the number and the engagement relationship of the gears in the two may also be adjusted according to design requirements, and only the first gear set 321 and the second gear set 322 need to be capable of realizing the linkage of the connecting element 311 and the pin 200, which is not limited in this embodiment.

Referring to fig. 20 in conjunction with fig. 17, fig. 20 is a schematic partial cross-sectional view of the power adapter 10 of fig. 6 taken along vii-vii.

As shown in fig. 17 and 20, when the connecting member 311 rotates to the first position relative to the main body 111, the second end 3112 of the connecting member 311 and the flip cover 312 may be located on a surface of the main body 111 perpendicular to the top surface 1101, that is, the third side surface 1105 or the fourth side surface 1106. At this time, the flip cover 312 may be in an open state, so that the pins 200 may be exposed for plugging with the socket. When the connecting member 311 is rotated to the second position relative to the main body 111, the second end 3112 of the connecting member 311 and the flip cover 312 can be located on the top surface 1101, and the flip cover 312 can further receive the conductive member 210 located on the top surface 1101 by the receiving groove 3122. In the present embodiment, the rotation angle range of the connection member 311 and the folder 312 may be 0-90 °. It should be understood that the first position and the second position are only one of the alternative embodiments of the present application, and the first position and the second position can be adjusted adaptively according to the design requirements of the power adapter 10, and the present application is not limited thereto.

Correspondingly, the number of the rotating mechanisms 300 can also be two, namely a first rotating mechanism 301 and a second rotating mechanism 302, and the first rotating mechanism 301 can be connected with the first pin 201 and linked with the first pin 201, and the second rotating mechanism 302 can be connected with the second pin 202 and linked with the second pin 202. When the first rotating mechanism 301 and the second rotating mechanism 302 rotate to the first position, the flip member 310 in the first rotating mechanism 301 may be located on the third side surface 1105, and the flip member 310 in the second rotating mechanism 302 may be located on the fourth side surface 1106. When the first rotating mechanism 301 and the second rotating mechanism 302 rotate to the second position, both the first rotating mechanism 301 and the second rotating mechanism 302 may be located on the top surface 1101, and the flip cover 312 in the first rotating mechanism 301 and the second rotating mechanism 302 may form an accommodating space together with the accommodating groove 3122 for accommodating the first pin 201 and the second pin 202. In addition, the linkage manner of the first rotating mechanism 301 and the first pin 201, and the linkage manner of the second rotating mechanism 302 and the second pin 202 are the same as the linkage manner of the rotating mechanism 300 and the pin 200 in the previous embodiment, and the description of this embodiment is omitted.

Referring to fig. 21 to 22, fig. 21 is another structural diagram of the power adapter 10 according to the embodiment of the present application, and fig. 22 is a partial sectional view of the power adapter 10 of fig. 21 along ix-ix.

As shown in fig. 21 to 22, since the flip 312 is connected to the main body 111 through the connecting member 311, there is a gap 102 between the flip 312 and the main body 111 due to an assembly tolerance or a gap 102 reserved to avoid interference of structural members. When a user needs to use the power adapter 10, the existence of the gap 102 may cause a certain safety hazard, and the safety of the power adapter 10 is reduced. Specifically, when the user completely opens the flip cover 312, the creepage distance of the power adapter 10 may be the distance from the pins 200 to the edge position of the flip cover 312 (D1 shown in fig. 22), and the creepage distance is long at this time, which can satisfy the safety design criterion. When the user does not completely open the flip cover 312, the creepage distance of the power adapter 10 may be the distance (D2 shown in fig. 22) from the pin 200 to the gap 102, and the creepage distance is short at this time, and cannot meet the safety design standard, so that there is a certain safety hazard. Based on this, the power adapter 10 in this embodiment may be provided with the flexible member 400 for blocking the gap 102, so that even in a state where the flip cover 312 is not fully opened, the creepage distance of the power adapter 10 may still be from the pins 200 to the edge position of the flip cover 312, so as to reduce the safety risk of the power adapter 10 during use.

Specifically, the flexible member 400 may be connected to the flip cap 312 and the main body 111, respectively, and may be bent along with the rotation of the connecting member 311 to prevent the flexible member 400 from affecting the opening and closing of the flip cap 312. Meanwhile, the flexible member 400 may have an insulating property, and may be used to shield the gap 102 between the flip 312 and the main body 111, so that even when the flip 312 is not completely opened, the creepage distance of the power adapter 10 may still be the distance from the pin 200 to the edge position of the flip 312, so as to meet the safety design standard of creepage distance, and reduce the safety risk of the power adapter 10 in the use process. In this embodiment, the flexible member 400 may be made of any one of bazaar, silicone, rubber, and leather.

The flip cover 312 may include: an outer housing 3123 and an inner housing 3124. The outer housing 3123 may be connected to the inner housing 3124, and the two may be enclosed together to form a cavity, so as to install the magnet by using the cavity, so that the flip 312 may absorb or repel the corresponding magnetic component by using the magnet, thereby implementing the corresponding function. Meanwhile, the housing 3123 may be connected with the flexible member 400, and the housing 3123 and the flexible member 400 may be an integrated structure, and both may be integrally formed using an injection molding process. Further, the flexible member 400 may be connected to the main body 111 by fixing means such as bonding, welding, and screwing. It should be understood that, in addition to the solution that the pins 200 are linked with the rotating mechanism 300, the flexible element 400 provided in this embodiment may also be applied to other common power adapters 10 with flip covers, which is not limited in this embodiment.

The power adapter 10 according to the embodiment of the present application is provided with the plug pins 200 inserted into the top surface 1101 of the fixing base 100, and the plug pins 200 can rotate relative to the fixing base 100 in a direction perpendicular to the top surface 1101 as an axis direction, and the rotating mechanism 300 located on the fixing base 100 and connected to the plug pins 200 and capable of rotating relative to the fixing base 100 to be interlocked with the plug pins 200, so that a user can change the state of the plug pins 200 by adjusting the position of the rotating mechanism 300. Meanwhile, when the rotating mechanism 300 rotates to the first position, the plug pin 200 can rotate to the first preset state capable of being plugged with the socket, and when the rotating mechanism 300 rotates to the second position, the plug pin 200 can rotate to the second preset state incapable of being plugged with the socket, so that the user can adjust the plug pin 200 to the second preset state for placing when the user does not need to use the power adapter 10. In this way, when a user without the ability to perform an autonomous behavior acquires the placed power adapter 10, the former cannot plug the plug pin 200 in the second preset state into the socket, which can reduce the security risk of the user using the power adapter 10.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
