Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a power adapter. Background Art

[0002] Power adapters are common electrical appliances in life, but they also have many inconveniences in situations where electrical appliances are used frequently. In traditional power adapters, the pins and the plug body are fixed as one. When not in use, due to its large size, it is extremely inconvenient to pack, transport and carry. Therefore, with the development of technology, foldable power adapters with foldable pins have emerged.

[0003] Today's foldable power adapters usually use a single-point supported spring or elastic plastic to achieve the flipping of the pins. However, the elastic parts with single-point support not only have poor resilience, but also have a short lifespan. After a long period of flipping, their elastic force will gradually decay, and they are also prone to loosening, shifting, and falling off during the flipping process. Utility Model Content

[0004] The power adapter provided in the embodiment of the present application can improve the resilience of the elastic conductive part, enhance the service life of the elastic conductive part, and also increase the reliability and stability of the elastic conductive part, so that the elastic conductive part is not easy to loosen and fall.

[0005] In a first aspect, an embodiment of the present application provides a power adapter, which includes a main body, a pin assembly, and an elastic conductive member.

[0006] The pin assembly is connected to the main body and can rotate relative to the main body between a first position and a second position.

[0007] The elastic conductive member is arranged inside the main body, and comprises a first supporting portion, a second supporting portion and an elastic abutting portion, wherein the elastic abutting portion is connected between the first supporting portion and the second supporting portion.

[0008] The elastic abutment portion is used to elastically abut the pin assembly, and is used to electrically contact the pin assembly when the pin assembly rotates to the first position, and to break away from electrical contact with the pin assembly when the pin assembly rotates to the second position. The first support portion and the second support portion are supported on the main body when the elastic abutment portion elastically abuts the pin assembly.

[0009] The beneficial effects of the present application are as follows: Different from the prior art, the present application provides an elastic conductive member with a first support portion and a second support portion in the power adapter, and when the elastic abutting portion abuts against the pin assembly to support the rotation of the pin assembly, the elastic conductive member can be supported on the main body through the two support points of the first support portion and the second support portion, so that the main body can provide support to the elastic conductive member through the two support points arranged at intervals, and share the pressure borne by the elastic conductive member through the two support points arranged at intervals, thereby improving the resilience of the elastic conductive member, reducing the elastic attenuation of the elastic conductive member, and thus improving the service life of the elastic conductive member, and can also increase the reliability and stability of the elastic conductive member, so that the elastic conductive member is not easy to loosen and fall. In addition, the elastic conductive member of the present application can elastically abut the pin assembly to support the rotation of the pin assembly, and can also be electrically connected to the pin assembly, so such a setting can simplify the internal structure of the power adapter and save resource costs.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The inventor of the present application has found that the foldable power adapters currently on the market usually use a single-point supported spring or elastic plastic to achieve the flipping of the pins, but the elastic member supported at a single point not only has poor resilience, but also has a short lifespan. After a long period of flipping, its elastic force will gradually decay, and it is also easy to loosen, shift, and fall during the flipping process. In order to solve the above problems, the present application proposes the following embodiments.

[0023] The following is an exemplary description of the power adapter according to the power adapter embodiment of the present application.

[0024] like Figures 1 to 8 As shown, the power adapter 10 may include a main body 100 , a pin assembly 200 and an elastic conductive member 300 .

[0025] The pin assembly 200 may be connected to the main body 100 and may rotate relative to the main body 100 between a first position and a second position.

[0026] The elastic conductive member 300 may be disposed inside the main body 100 , and may include a first supporting portion 310 , a second supporting portion 320 , and an elastic abutting portion 330 . The elastic abutting portion 330 is connected between the first supporting portion 310 and the second supporting portion 320 .

[0027] The elastic abutment portion 330 is used to elastically abut the pin assembly 200 and to electrically contact the pin assembly 200 when the pin assembly 200 rotates to the first position, and to lose electrical contact with the pin assembly 200 when the pin assembly 200 rotates to the second position.

[0028] For reference Figures 1 to 8 When the pin assembly 200 is in the first position, Figure 1 , Figure 5 and Figure 6 As shown, when the pin assembly 200 is in the second position, Figure 2 , Figure 7 and Figure 8 Specifically, when the pin assembly 200 is rotated to the first position, the pin assembly 200 is inserted into the corresponding socket hole for use and is electrically connected to the socket. When the pin assembly 200 is rotated to the first position, the pin assembly 200 can be in a storage state, and the pin assembly 200 is out of electrical contact with the elastic abutment portion 330, so that the pin assembly 200 is in a power-off state.

[0029] The pin assembly 200 is arranged in this way, so that the power adapter 10 is in a non-current state when in the storage state, thereby improving the safety of the power adapter 10. In addition, the pin assembly 200 can be rotated relative to the main body 100, which can improve the flexibility of the power adapter 10, so that the power adapter 10 can occupy less storage space when not in use, so that the power adapter 10 can be stored and carried.

[0030] The elastic conductive element 300 may be a metal spring, or a combination of a plastic elastic wall and a metal spring, or a metal elastic splitter. The elastic conductive element 300 is not specifically limited in this embodiment.

[0031] Specifically, the elastic conductive member 300 can not only elastically support the pin assembly 200 to rotate relative to the main body 100, but also form electrical contact with the pin assembly 200 when the pin assembly 200 is in the first position, so that the pin assembly 200 can form a current path with other components through the elastic conductive member 300. The setting of combining the elastic element and the conductive element into one can not only simplify the internal structure of the power adapter 10, but also save costs.

[0032] Furthermore, the elastic contact portion 330 is used to elastically contact the pin assembly 200. The first support portion 310 and the second support portion 320 are used to support the main body 100 when the elastic contact portion 330 elastically contacts the pin assembly 200.

[0033] Since the elastic abutment portion 330 is disposed between the first support portion 310 and the second support portion 320 , when the elastic abutment portion 330 elastically abuts against the pin assembly 200 , the first support portion 310 and the second support portion 320 can support the elastic abutment portion 330 on both sides of the elastic abutment portion 330 to share the pressure borne by the elastic abutment portion 330 .

[0034] Through the above arrangement, the main body 100 can provide support to the elastic conductive member 300 through two supporting points, and the pressure on the elastic conductive member 300 is shared through the two supporting points, thereby improving the resilience of the elastic conductive member 300, reducing the elastic attenuation of the elastic conductive member 300, and further improving the service life of the elastic conductive member 300. The arrangement of the two supporting points of the elastic conductive member 300 can increase the reliability and stability of the elastic conductive member 300, so that the elastic conductive member 300 is not easy to loosen and fall off.

[0035] In some embodiments, Figures 3 to 6 As shown, the main body 100 may include a main shell 110 and a bearing seat 120 , and the pin assembly 200 is rotatably connected to the main shell 110 .

[0036] In some embodiments, Figures 3 to 6 As shown, the main shell 110 may be provided with a receiving cavity 111 and a mounting hole 112 connected to the receiving cavity 111. The mounting hole 112 connects the outside and the receiving cavity 111. The bearing seat 120 may be arranged in the receiving cavity 111. The elastic conductive member 300 may be arranged in the bearing seat 120, and the elastic abutment portion 330 is arranged opposite to the mounting hole 112. The elastic conductive member 300 may extend to the mounting hole 112 or may extend out of the mounting hole 112, and the pin assembly 200 may abut against the elastic abutment portion 330 in the mounting hole 112. Alternatively, the elastic conductive member 300 may also be arranged inside the receiving cavity 111, and the pin assembly 200 may extend from the mounting hole 112 into the receiving cavity 111 to elastically abut against the elastic conductive member 300.

[0037] Optionally, the main shell 110 may further include an upper shell 115 and a lower shell 116 . The upper shell 115 and the lower shell 116 may be assembled with each other to enclose a receiving cavity 111 , and the supporting seat 120 is disposed between the upper shell 115 and the lower shell 116 .

[0038] Optionally, the main shell 110 and the bearing seat 120 may be fixed to each other by snap-fitting, and the first support portion 310 may be relatively fixed between the main shell 110 and the bearing seat 120 after being pressed by the main shell 110 and the bearing seat 120 .

[0039] In some embodiments, Figures 3 to 6 As shown, the first support portion 310 and the second support portion 320 can be fixedly arranged relative to the main body 100. Such an arrangement can make the connection between the elastic conductive member 300 and the main body 100 more stable, so that the elastic conductive member 300 is not easy to loosen and fall off.

[0040] Alternatively, at least one of the first supporting portion 310 and the second supporting portion 320 may be movably arranged relative to the main body 100, so as to be supported on the main body 100 when the elastic abutting portion 330 elastically abuts against the pin assembly 200. For example, one of the first supporting portion 310 and the second supporting portion 320 may be movably arranged relative to the main body 100, and when the elastic abutting portion 330 elastically abuts against the pin assembly 200, the movable first supporting portion 310 or the second supporting portion 320 is pressed by the pin assembly 200 and abuts against the main body 100 to support the elastic conductive member 300. Such an arrangement can make the arrangement of the elastic conductive member 300 more flexible, and can also facilitate the installation of the elastic conductive member 300.

[0041] In some embodiments, the first support portion 310 and the second support portion 320 are fixedly arranged relative to the main body 100 and may include the following structure:

[0042] like Figure 3 and Figure 6 As shown, the first support portion 310 is relatively fixed to the main body 100 when the elastic abutting portion 330 elastically abuts against the pin assembly 200 , so that when the elastic abutting portion 330 elastically abuts against the pin assembly 200 , the main body 100 can fix the elastic conductive member 300 by fixing the first support portion 310 .

[0043] In some embodiments, the first support portion 310 may be connected to the main body 100 by snap-fitting.

[0044] Alternatively, if Figure 5 and Figure 6 As shown, the main body 100 may be provided with a first locking column 130, and the first support portion 310 is provided with a first locking hole 311. The first support portion 310 is sleeved on the first locking column 130 through the first locking hole 311, so as to be relatively fixed with the main body 100 when the elastic abutment portion 330 elastically abuts against the pin assembly 200. The first locking column 130 may be provided on the main shell 110.

[0045] Through the above arrangement, the structure of the power adapter 10 can be simplified, so that the elastic conductive member 300 can be relatively fixed to the main body 100 through a simple structure.

[0046] Furthermore, if Figure 6As shown, the bearing seat 120 may be provided with a receiving hole 121, the first support portion 310 may be clamped between the main shell 110 and the bearing seat 120, the first positioning hole 311 and the receiving hole 121 may be arranged opposite to each other and communicate with each other, and the first positioning hole 311 is arranged through the first positioning hole 311 and extends into the receiving hole 121. In this arrangement, the main shell 110 and the bearing seat 120 cooperate with each other to fix the first support portion 310, which not only makes the arrangement of the elastic conductive member 300 more stable, but also makes the internal structure of the main body 100 more compact, and also facilitates the installation and removal of the power adapter 10.

[0047] Optionally, the second support portion 320 may be fixedly disposed on the bearing seat 120. A first implementation of the second support portion 320 is as follows:

[0048] For reference Figure 5 and Figure 6 The main body 100 may be provided with a second locking column 150, and the second support portion 320 may be provided with a second locking hole 321. The second support portion 320 may be sleeved on the second locking column 150 through the second locking hole 321 so as to be relatively fixed with the main body 100 when the elastic abutting portion 330 elastically abuts against the pin assembly 200.

[0049] Optionally, the second locking column 150 may be disposed on the bearing seat 120, and the second support portion 320 may be stacked with the bearing seat 120 to be supported on the bearing seat 120. The extension direction of the second locking column 150 may be perpendicular to the arrangement direction of the first support portion 310 and the second support portion 320. Figure 6 The second support portion 320 can be stacked with the second locking column 150 of the bearing seat 120 in the extending direction.

[0050] Or in other embodiments, the second locking column 150 can be arranged on the side of the bearing seat 120 opposite to the first support portion 310, the second support portion 320 can be stacked with the bearing seat 120 along the arrangement direction of the first support portion 310 and the second support portion 320, and the extension direction of the second locking column 150 can be consistent with the arrangement direction of the first support portion 310 and the second support portion 320. When the elastic abutment portion 330 elastically abuts the pin assembly 200, the second support portion 320 is fixed to the side of the bearing seat 120 through the second locking hole 321 and the second locking column 150 to be supported on this side.

[0051] Such a configuration can make the structure of the elastic conductive member 300 more stable, and prevent the elastic abutting portion 330 from loosening and falling off.

[0052] In some other embodiments, the second support portion 320 may be movably disposed relative to the main body 100. A second embodiment of the second support portion 320 is as follows:

[0053] See also Fig. 9 and Fig.10 The second support portion 320 may be movably disposed relative to the main body 100. The main body 100 may be provided with a support slope 140. The second support portion 320 is used to be slidably and elastically supported on the support slope 140 when the elastic abutting portion 330 elastically abuts against the pin assembly 200.

[0054] Specifically, the elastic conductive member 300 may have a free end, which is bent toward the first support portion 310 to form the second support portion 320 bent in an arc shape. The support slope 140 is inclined relative to the arrangement direction of the first support portion 310 and the second support portion 320 and faces the first support portion 310.

[0055] The arrangement direction of the first support portion 310 and the second support portion 320 can be as follows: Fig.10 As shown by the arrow G in the figure, the extension direction of the support slope 140 is as follows Fig.10 As shown by the arrow H, the H direction is inclined compared to the G direction. The support slope 140 may be oriented opposite to the first support portion 310 , so that the support slope 140 can support the second support portion 320 when the elastic contact portion 330 elastically contacts the pin assembly 200 .

[0056] Specifically, since the elastic abutment portion 330 is arranged between the first support portion 310 and the second support portion 320, when the elastic abutment portion 330 elastically abuts against the pin assembly 200, the first support portion 310 and the second support portion 320 are subjected to force and have a tendency to move toward both sides of the elastic abutment portion 330. Therefore, the supporting inclined surface 140 is arranged to be inclined in the arrangement direction of the first support portion 310 and the second support portion 320, and toward the first support portion 310, so that the second support portion 320 can be supported and restricted by the supporting inclined surface 140 after being subjected to force, so that the supporting inclined surface 140 can restrict the movement of the second support portion 320.

[0057] The second support portion 320 with an arc-shaped free end can not only allow the second support portion 320 to be restricted by the support slope 140 in multiple directions, but also prevent the second support portion 320 from damaging the support slope 140 when the support slope 140 supports the second support portion 320, and facilitates the assembly and disassembly of the elastic conductive part 300.

[0058] Of course, in other embodiments, the second support portion 320 may also be in other configuration forms, such as being welded to the support seat 120 , etc., which will not be listed in detail one by one in this application.

[0059] In some embodiments, Figures 3 to 10As shown, the elastic abutment portion 330 can be arranged to be arched relative to the first support portion 310 and the second support portion 320 toward the pin assembly 200. Such an arrangement can facilitate the pin assembly 200 to abut against the elastic abutment portion 330, and the elastic abutment portion 330 can be arranged in the rotation path of the pin assembly 200, so that the elastic abutment portion 330 elastically abuts against the pin assembly 200 during the rotation of the pin assembly 200.

[0060] In some embodiments, Figures 4 to 6 As shown, the elastic abutting portion 330 may include an abutting section 331 and a supporting section 332, wherein the first end of the abutting section 331 is connected to the first supporting portion 310, and the first end of the supporting section 332 is connected to the second supporting portion 320. The second end of the abutting section 331 and the second end of the supporting section 332 are respectively extended in the direction close to the pin assembly 200 and connected to each other, so that the elastic abutting portion 330 is arched.

[0061] The abutting section 331 is used for elastically abutting against the pin assembly 200 , and the supporting section 332 is used for elastically supporting the abutting section 331 when the abutting section 331 abuts against the pin assembly 200 .

[0062] Optionally, when the abutting section 331 elastically abuts against the pin assembly 200 , the abutting section 331 will undergo elastic deformation, and the abutting section 331 will also drive the supporting section 332 to undergo elastic deformation to allow the pin assembly 200 to rotate, and the supporting section 332 can further support the abutting section 331 through the second supporting portion 320 .

[0063] Optionally, the elastic coefficient of the supporting section 332 may be smaller than that of the abutting section 331 , so that the supporting section 332 can better support the abutting section 331 and make the abutting section 331 have better resilience.

[0064] Through the above arrangement, the elastic conductive member 300 can be conveniently used to elastically support the pin assembly 200 to rotate, and the resilience of the elastic conductive member 300 can be improved, thereby increasing the service life of the elastic conductive member 300 .

[0065] In some embodiments, Figures 4 to 6 As shown, in the arrangement direction of the first support portion 310 and the second support portion 320, the connection position of the second end of the abutment segment 331 and the second end of the support segment 332 is farther away from the first end of the abutment segment 331 than the first end of the support segment 332, so that the abutment segment 331 can be inclined toward the direction of the first end of the support segment 332.

[0066] In some embodiments, the angle between the abutment section 331 and the support section 332 may be an acute angle. Figure 6 As shown, the angle between the abutment section 331 and the support section 332 may be as follows: Figure 6Such a configuration allows the abutment section 331 to elastically abut against the pin assembly 200, and facilitates the abutment section 331 to drive the support section 332 to deform, so that the elastic abutment section 330 has better elasticity, and facilitates the pin assembly 200 to rotate under the elastic support of the elastic abutment section 330. Of course, in other embodiments, the angle between the abutment section 331 and the support section 332 can be a right angle, an obtuse angle, or other angles.

[0067] In some embodiments, the extension direction of the abutting section 331 intersects with the arrangement direction of the first supporting portion 310 and the second supporting portion 320, and intersects with the thickness direction of the abutting section 331. Figure 6 As shown in the direction I, the thickness direction of the abutting section 331 is as follows Figure 6 As shown in J. The structure of the abutting section 331 is set in this way, so that when the abutting section 331 elastically abuts against the pin assembly 200, the abutting section 331 can elastically support the pin assembly 200 better and more firmly, so as to facilitate the rotation of the pin assembly 200.

[0068] See also Figures 3 to 8 , the pin assembly 200 may include an electrode pin 210 and a fixing seat 220. The electrode pin 210 may be inserted into the fixing seat 220, and the fixing seat 220 may be rotatably connected to the main body 100. The fixing seat 220 may rotate between a first position and a second position relative to the main body 100. The electrode pin 210 and the fixing seat 220 may rotate together relative to the main body 100, so that the electrode pin 210 can be in electrical contact with the elastic conductive member 300 in the first position, and be out of electrical contact with the elastic conductive member 300 in the second position.

[0069] Optionally, the electrode pin 210 may have a connection pin 211 and an abutment pin 212 disposed opposite to each other, the connection pin 211 being used for plugging and mating with an external device, and the abutment pin 212 being used for electrically contacting the elastic conductive member 300 when the pin assembly 200 is located at the first position.

[0070] Specifically, when the fixing base 220 rotates to the first position, the abutting pin 212 abuts against the elastic abutting portion 330 to make electrical contact with the elastic conductive member 300. When the fixing base 220 rotates to the second position, the abutting pin 212 and the elastic abutting portion 330 are separated from each other. With such a configuration, the electrode pin 210 can be in a non-powered state when the power adapter 10 is not in use, thereby improving the safety of the power adapter 10.

[0071] In some embodiments, Figure 6As shown, a groove 340 may be formed at the connection between the elastic abutment portion 330 and the first support portion 310. When the fixing seat 220 rotates to the first position, the abutment pin 212 may be embedded in the groove 340, so that the pin assembly 200 is positioned at the first position.

[0072] The shape of the groove 340 can be adapted to the shape of the end of the abutting foot 212, so that the groove 340 can better position the abutting foot 212 at the first position. For example, the shape of the groove 340 can be semicircular, and the shape of the end of the abutting foot 212 can also be semicircular. This configuration allows the groove 340 to better restrict the abutting foot 212, and also facilitates the power adapter 10 to push the abutting foot 212 away from the groove 340 when rotating.

[0073] In some embodiments, Figures 5 to 8 As shown, the fixing seat 220 can abut against the elastic abutment portion 330 when rotating to the first position and the second position. Optionally, the electrode pin 210 can also abut against the elastic abutment portion 330 when rotating between the first position and the second position.

[0074] In some embodiments, Figures 3 to 8 As shown, the elastic abutting portion 330 may be provided with an elastic abutting surface 333 .

[0075] Optionally, the elastic abutting surface 333 may be disposed on the abutting section 331, and may be disposed on a side of the abutting section 331 away from the supporting section 332. The fixing seat 220 and the elastic abutting portion 330 may both abut against the elastic abutting surface 333 during the rotation process.

[0076] Specifically, Figures 3 to 8 As shown, the fixing seat 220 may be provided with a first abutting inclined surface 221 and a second abutting inclined surface 222. The first abutting inclined surface 221 and the second abutting inclined surface 222 may be arranged at an angle, and the abutting foot 212 passes through between the first abutting inclined surface 221 and the second abutting inclined surface 222 to the outside of the fixing seat 220. The first abutting inclined surface 221 and the second abutting inclined surface 222 may be arranged corresponding to the elastic abutting surface 333.

[0077] When the fixing seat 220 rotates to the first position, the first abutting slope 221 can abut against the elastic abutting surface 333, and the abutting foot 212 abuts against the elastic abutting portion 330. The elastic abutting surface 333 can be used to elastically support the first abutting slope 221, so that the pin assembly 200 remains in the first position.

[0078] With such a configuration, the pin assembly 200 can determine the position of the electrode pin 210 through the first abutment slope 221 and the elastic abutment portion 330, so that the end of the electrode pin 210 of the pin assembly 200 in the first position can fit into the groove 340 and form an electrical contact with the elastic conductive member 300, and can also further control the orientation direction of the fixed electrode pin 210 to facilitate the connection and cooperation between the connector pin 211 of the electrode pin 210 and the external device.

[0079] like Figure 7 and Figure 8 As shown, when the fixing base 220 rotates to the second position, the second abutting inclined surface 222 can abut against the elastic abutting surface 333, and the abutting pin 212 and the elastic abutting portion 330 are separated from each other, and the elastic abutting surface 333 can be used to elastically support the second abutting inclined surface 222, so that the pin assembly 200 is maintained in the second position. By setting the second abutting inclined surface 222 to abut against the elastic abutting surface 333 when the pin assembly 200 is in the second position, the second abutting inclined surface 222 can further fix the orientation of the electrode pin 210, so that the power adapter 10 is always in a folded state when not in use, thereby improving the safety and stability of the power adapter 10.

[0080] In some embodiments, the elastic force applied by the elastic abutment portion 330 to the fixing base 220 when the fixing base 220 rotates to the first position may be smaller than the elastic force applied to the fixing base 220 when the fixing base 220 rotates to the second position.

[0081] When the fixing base 220 is rotated to the second position, the power adapter 10 is in a folded state, so the elastic force applied by the elastic abutment portion 330 to the fixing base 220 is increased, so that the pin assembly 200 can be stabilized in the second position to ensure the stability and safety of the power adapter 10. When the fixing base 220 is rotated to the first position, the elastic force applied by the elastic abutment portion 330 to the fixing base 220 is smaller than the elastic force applied to the fixing base 220 when the fixing base 220 is rotated to the second position, so that the pin assembly 200 can be easily rotated from the first position to the second position.

[0082] In some embodiments, Figures 5 to 8 As shown, the fixing base 220 can rotate from the second position to the first position along the positive rotation direction, and can rotate from the first position to the second position along the reverse rotation direction. In this way, the turning process of the fixing base 220 can be limited to one path, thereby simplifying the movement path of the pin assembly 200, so as to facilitate the user to operate the pin assembly 200 described in the present application.

[0083] Optionally, the fixing seat 220 is rotatably connected to the main body 100 and is located outside the accommodating cavity 111, and can elastically abut against the elastic conductive member 300 outside the accommodating cavity 111. Alternatively, the fixing seat 220 can partially extend to the mounting hole 112, and elastically abut against the elastic conductive member 300 in the mounting hole 112. Of course, in other embodiments, the fixing seat 220 can extend from the mounting hole 112 into the accommodating cavity 111, and elastically abut against the elastic conductive member 300 in the accommodating cavity 111.

[0084] Alternatively, if Figures 3 to 8 As shown, the fixed seat 220 may include a fixed abutting portion 223 for abutting against the elastic abutting portion 330 , and the abutting foot 212 passes through the fixed abutting portion 223 to the outside of the fixed seat 220 . The first abutting inclined surface 221 and the second abutting inclined surface 222 may be disposed on the fixed abutting portion 223 .

[0085] Specifically, when the fixing seat 220 rotates to the first position, the hole wall of the mounting hole 112 can be used to limit the fixing abutment portion 223 to restrict the fixing seat 220 from continuing to rotate along the positive direction, thereby limiting the fixing seat 220 to the first position.

[0086] Alternatively, if Figure 3 As shown, the number of the elastic conductive members 300 can be two, and the number of the mounting holes 112 can also be two. The two elastic conductive members 300 can be disposed on the bearing seat 120, corresponding to the two mounting holes 112 one by one and arranged opposite to each other.

[0087] Optionally, the number of the fixed abutting portions 223 can be two, and the two fixed abutting portions 223 are arranged at intervals. The number of the electrode pins 210 can also be two, and one of the two electrode pins 210 can be a negative electrode pin and the other can be a positive electrode pin. The abutting pins 212 of the two electrode pins 210 pass through the two fixed abutting portions 223 to the outside of the fixing seat 220 respectively.

[0088] Specifically, the two elastic conductive members 300, the two mounting holes 112 and the two fixed abutting portions 223 can be arranged in a one-to-one correspondence. The two fixed abutting portions 223 and the two electrode pins 210 can partially extend to the two mounting holes 112 or extend from the two mounting holes 112 into the accommodating cavity 111, and respectively abut against the two elastic conductive members 300.

[0089] In some embodiments, Figure 3 As shown, the main housing 110 may be protrudingly provided with a mounting portion 113 located between the two mounting holes 112, and two fixed abutting portions 223 are located on both sides of the mounting portion 113. The two fixed abutting portions 223 may be connected to the mounting portion 113, so that the mounting portion 113 can further define the position of the pin assembly 200.

[0090] Optional, such as Figures 3 to 8 As shown, the main shell 110 may be provided with a blocking portion 117 on both sides of the mounting portion 113, and the blocking portion 117 may partially surround the corresponding mounting hole 112. When the fixing seat 220 is rotated to the second position, the blocking portion 117 may be used to be arranged opposite to the abutting pin 212 to cover the abutting pin 212. Such a setting allows the blocking portion 117 to block the abutting pin 212 when the power adapter 10 is not in use, so that the abutting pin 212 is not easily exposed to the outside and electrically contacted with other conductive elements, thereby ensuring that when the pin assembly 200 is in the second position, the electrode pin 210 is in a non-conductive state, so as to improve the safety of the power adapter 10.

[0091] Optionally, an installation space 131 communicating with the accommodating cavity 111 may be provided in the installation portion 113 .

[0092] In some embodiments, see Figures 3 to 8 The fixing base 220 may include a pin bracket 224 , an upper cover 225 and a bottom cover 226 .

[0093] The pin bracket 224 can be fixedly coated on the electrode pin 210 by injection molding, and the connecting pin 211 and the abutting pin 212 are exposed. The injection molding coating method can make the pin bracket 224 adapt to the shape of the electrode pin 210, thereby strengthening the connection between the pin bracket 224 and the electrode pin 210, so that the pin bracket 224 and the electrode pin 210 are not easy to separate from each other.

[0094] Furthermore, the upper cover 225 and the bottom cover 226 are covered to fix the pin bracket 224 between the upper cover 225 and the bottom cover 226, so as to fix the electrode pin 210 relative to the upper cover 225 and the bottom cover 226. The connecting pin 211 and the abutting pin 211 can be respectively extended to the upper cover 225 and the bottom cover 226.

[0095] The bottom cover 226 may be provided with the above-mentioned fixed abutting portion 223 .

[0096] Optionally, the bottom cover 226 is rotatably connected to the main body 100 and is located outside the accommodating cavity 111, and the bottom cover 226 is provided with two fixed abutting portions 223 spaced from each other. The two fixed abutting portions 223 can be located on both sides of the mounting portion 113. And the two fixed abutting portions 223 can abut against two elastic conductive members 300.

[0097] In some embodiments, Figures 6 to 10As shown, the bottom cover 226 may also be provided with a receiving groove 2261. When the fixing base 220 rotates to the first position, the mounting portion 113 is received in the receiving groove 2261, and the retaining portion 117 of the mounting portion 113 may stop the bottom cover 226 in the receiving groove 2261 to limit the fixing base 220 from continuing to rotate in the positive direction.

[0098] Furthermore, the receiving groove 2261 can cover the mounting portion 113 when the fixing base 220 rotates to the first position, thereby making the power adapter 10 more beautiful.

[0099] In some embodiments, Figure 3 and Fig.11 As shown, the power adapter 10 may include two rotating shafts 400 and an elastic member 500. The two rotating shafts 400 may be disposed on the mounting portion 113, and the elastic member 500 may be disposed in the mounting space 131.

[0100] A shaft hole 2231 may be opened on the opposite sides of the two fixed abutment portions 223, and the elastic member 500 is connected between one ends of the two shafts 400. The other ends of the two shafts 400 are elastically supported by the elastic member 500 and are inserted into the two shaft holes 2231 rotatably in a one-to-one manner.

[0101] Therefore, the two rotating shafts 400 can be fixed by the cooperation between the mounting portion 113 and the elastic member 500, and the two rotating shafts 400 can pass through the mounting portion 113 and be inserted into the rotating shaft holes 2231 of the two fixed abutting portions 223, which can further limit the position of the pin assembly 200 so that the pin assembly 200 is not easy to fall from the main body 100.

[0102] Optionally, the portions of the two rotating shafts 400 inserted into the two rotating shaft holes 2231 may be cylindrical, and the two rotating shaft holes 2231 may both be circular, so that the pin assembly 200 can be easily rotated relative to the main body 100 .

[0103] In some embodiments, the two shafts 400 can be brought close to each other to compress the elastic member 500, and then withdraw from the two shaft holes 2231. The two shafts 400 can be movably arranged by the elastic member 500, which can make the pin assembly 200 easy to install and disassemble, and can also improve the compactness of the structure of the power adapter 10.

[0104] In some embodiments, Figure 3 and Fig.11As shown, the bearing seat 120 may be protrudingly provided with a stopper 122 extending into the installation space 131, and the stopper 122 is used to stop one end of one of the rotating shafts 400 to limit the movement of one of the rotating shafts 400 toward the other rotating shaft 400, thereby allowing the other rotating shaft 400 to move toward one of the rotating shafts 400 and exit the corresponding rotating shaft hole 2231. Providing the stopper 122 to stop one rotating shaft 400 can make the setting of the rotating shaft 400 more stable and less likely to loosen or fall off.

[0105] Of course, in other embodiments, the two rotating shafts 400 may also be able to move relative to each other and exit the corresponding rotating shaft holes 2231 .

[0106] In some embodiments, Figure 3 and Figure 5 As shown, the power adapter 10 may further include a circuit board 600 and a socket 700 connected to the circuit board 600. The circuit board 600 and the socket 700 may both be disposed in the accommodating cavity 111.

[0107] The circuit board 600 may be a PCB (Printed Circuit Board), which can integrate analog circuits composed of capacitors, resistors, transistors, etc. and process analog signals. The socket 700 may be an interface 710 such as Type-A or Type-C, which can be plugged into a corresponding plug to connect other devices.

[0108] Specifically, the circuit board 600 can be electrically connected to the elastic conductive member 300, so that the circuit board 600 can be electrically connected to the electrode pin 210 through the elastic conductive member 300, and the electrode pin 210 can be connected to the socket 700 through the elastic conductive member 300 and the circuit board 600 in turn. Therefore, when the socket 700 is connected to other devices, the electrode pin 210 can be connected to the other devices, so that the power adapter 10 can be used as a plug converter.

[0109] Optionally, the main housing 110 may be provided with a communication hole 114 connecting the accommodating cavity 111 and the outside, and the interface 710 of the socket 700 may correspond to the communication hole 114, so that the interface 710 of the socket 700 can be connected with the outside through the communication hole 114. The communication hole 114 and the pin assembly 200 may be provided on different sides, so that when the pin assembly 200 is inserted into the corresponding socket for use, the communication hole 114 and the interface 710 of the socket 700 are not easily blocked.

[0110] In summary, the present application provides an elastic conductive member 300 having a first supporting portion 310 and a second supporting portion 320 which are arranged at intervals in the power adapter 10, and when the elastic abutting portion 330 abuts against the pin assembly 200 to support the rotation of the pin assembly 200, the elastic conductive member 300 can be supported on the main body 100 by the two supporting points of the first supporting portion 310 and the second supporting portion 320, so as to further fix and support the elastic conductive member 300, so that the main body 100 can provide support to the elastic conductive member 300 through the two supporting points which are arranged at intervals, and share the pressure borne by the elastic conductive member 300 through the two supporting points which are arranged at intervals, thereby improving the resilience of the elastic conductive member 300, reducing the elastic attenuation degree of the elastic conductive member 300, and further improving the service life of the elastic conductive member 300, and can also increase the reliability and stability of the elastic conductive member 300, so that the elastic conductive member 300 is not easy to loosen and fall. Furthermore, the elastic conductive member 300 of the present application can elastically abut the pin assembly 200 to support the rotation of the pin assembly 200, and can also be electrically connected to the pin assembly 200. Therefore, such a configuration can simplify the internal structure of the power adapter 10 and save resource costs.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
