Description

Technical Field

[0001] The present application belongs to the field of electronic technology, and specifically relates to a power adapter. Background Art

[0002] With the advancement of technology, mobile phones and other electronic devices have become necessities in people's lives. Power adapters are usually used to charge mobile phones and other electronic devices. Existing power adapters usually include pins for plugging into sockets. However, due to the size limitation of the power adapter, the pins are prone to leakage when plugged into the socket, causing harm to users. Summary of the invention

[0003] In view of this, the present application provides a power adapter, which has a closed state and an open state, including:

[0004] A pin assembly, comprising a pin and a bracket, wherein the bracket comprises a connecting end and a fixing end arranged opposite to each other, and the pin is connected to the connecting end;

[0005] a sleeve, which is sleeved and slidably connected to the bracket, and the sleeve can slide in a direction close to or away from the fixed end; when the power supply is adapted to the turned-on state, at least part of the pins protrude from the sleeve; and

[0006] The movable part includes a first end arranged on the side of the sleeve away from the fixed end. When the power adapter moves from the closed state to the open state, the sleeve slides in a direction close to the fixed end and moves the first end in a direction away from the pin, thereby causing the first end to protrude from the sleeve.

[0007] The present application provides a power adapter with a novel structure, which adds a sleeve and a moving part, so that the sleeve is sleeved on the bracket and is slidably connected with the bracket, so that the sleeve can slide in the direction close to or away from the fixed end. Specifically: when the sleeve slides in the direction away from the fixed end and the distance from the fixed end is the largest, it can be understood as a closed state. When the sleeve slides in the direction close to the fixed end and the distance from the fixed end is the smallest, it can be understood as an open state. When the power adapter is adapted to the open state, at least part of the pins protrude from the sleeve, so that the pins can be inserted into the socket for use.

[0008] In addition, the present application can also make the first end of the movable part be arranged on the side of the sleeve away from the fixed end. And when the power adapter is in the process of changing from the closed state to the open state, the sleeve slides in the direction close to the fixed end, and makes the first end move in the direction away from the pin, so that the first end protrudes from the sleeve. That is, the sleeve can make the first end of the movable part open outward while sliding, thereby increasing the distance between the surface of the first end away from the pin and the pin. In this way, when the user touches the surface of the first end away from the pin, the creepage distance can be increased, thereby improving the safety performance of the power adapter and preventing the pin from leaking electricity when inserted into the socket, thereby preventing harm to the user.

DETAILED DESCRIPTION

[0031] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0032] Before introducing the technical solution of the present application, the technical problems in the related technology are introduced in detail.

[0033] As mobile phones and other electronic devices continue to develop, the corresponding power adapters are also developing and improving. Electronic devices are usually equipped with rechargeable batteries, and power adapters usually include an adapter body and a plug. When the plug is inserted into a socket and the power adapter is electrically connected to the electronic device through a charging cable, the rechargeable battery can be charged.

[0034] At present, power adapters are developing towards miniaturization, but the continuously shrinking power adapters will cause the distance between the edge of the plug close to the adapter body and the outer surface of the adapter body to continue to decrease. When it is less than a certain distance (for example, 6.5mm), when the power adapter is charging, when the user's finger touches the outer surface, it will cause the creepage distance to be too short, so that the electric energy on the plug is transferred to the user's finger through the adapter body, resulting in leakage, thereby causing harm to the user. Therefore, it is urgently needed to seek a power adapter with a small size and leakage prevention.

[0035] In view of this, in order to solve the above problems, this application provides a power adapter. Please refer to Figure 1-Figure 5 , Figure 1 Schematic diagram of the application environment of the power adapter in one embodiment of the present application. Figure 2 It is a schematic diagram of the three-dimensional structure when the power adapter is in a closed state in one embodiment of the present application. Figure 3 It is a schematic diagram of the structure of a pin assembly in one embodiment of the present application. Figure 4 This is a schematic diagram of the three-dimensional structure when the power adapter is in an open state in one embodiment of the present application. Figure 5 for Figure 4A schematic cross-sectional view along the AA direction in FIG. This embodiment provides a power adapter 1, and the power adapter 1 has a closed state and an open state. Specifically, the power adapter 1 includes a pin assembly 10, a sleeve 20, and a movable member 30. Among them, the pin assembly 10 includes a pin 11 and a bracket 12, and the bracket 12 includes a connecting end 121 and a fixed end 122 arranged opposite to each other, and the pin 11 is connected to the connecting end 121. The sleeve 20 is sleeved and slidably connected to the bracket 12, and the sleeve 20 can slide in a direction close to or away from the fixed end 122; when the power adapter is in the open state, at least part of the pin 11 protrudes from the sleeve 20. The movable member 30 includes a first end 31 disposed on the side of the sleeve 20 away from the fixed end 122. When the power adapter 1 moves from the closed state to the open state, the sleeve 20 slides toward the fixed end 122 and moves the first end 31 toward a direction away from the pin 11, thereby causing the first end 31 to protrude from the sleeve 20.

[0036] The power adapter 1 provided in this embodiment is a conversion device for providing power to the electronic device 2. Generally, the power adapter 1 can convert AC voltage into DC voltage. Figure 1 As shown, the power adapter 1 is plugged into the socket 3, receives the AC voltage output by the socket 3, and converts the received AC voltage into a DC voltage, which is used to charge the electronic devices 2 such as mobile phones and computers. It can be understood that in other embodiments, the power adapter 1 converts the received AC voltage into a DC voltage, and the DC voltage is directly used for the electronic components in the electronic device 2. It can be understood that the application environment diagram of the power adapter 1 only helps to understand the application of the power adapter 1, and should not be understood as a limitation of the power adapter 1 provided in this application.

[0037] In addition, the electronic device 2 referred to in this embodiment generally includes but is not limited to mobile terminals such as mobile phones, tablet computers, laptop computers, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and fixed terminals such as digital TVs and desktop computers. This embodiment is illustrated by taking the electronic device 2 as a mobile phone.

[0038] In addition, the power adapter 1 has an open state and also has a closed state corresponding to the open state, which means that the power adapter 1 is movable, that is, closed and opened, and the closing and opening result in the plug 11 being hidden and exposed. As for the specific state, the present application will be described below.

[0039] The power adapter 1 provided in this embodiment includes a pin assembly 10, and the pin assembly 10 includes a connected pin 11 and a bracket 12. The pin assembly 10 is composed of a bracket 12 and a pin 11. The material of the pin 11 is conductive metal, and the pin 11 is plugged into the socket 3 to receive the AC voltage provided by the socket 3. The number of the pins 11 can be but is not limited to two. In this embodiment, the number of the pins 11 is two. The two pins 11 are arranged oppositely and at intervals. The pin 11 can be but is not limited to a long strip. The end of the pin 11 away from the bracket 12 is arc-shaped to facilitate the insertion of the pin 11 into the socket 3. When the pin 11 is inserted into the socket 3 to receive the first voltage, the circuit board is electrically connected to the pin 11 to receive the first voltage transmitted by the pin 11, and the circuit board is used to convert the first voltage into a second voltage, and the second voltage is used to charge the battery.

[0040] As for the structure of the bracket 12 for setting the pin 11, the bracket 12 has two ends arranged opposite to each other, namely a connecting end 121 and a fixing end 122. The pin 11 of this embodiment is connected to the connecting end 121. That is, the connecting end 121 is used to connect the pin 11, while the fixing end 122 is not connected to the pin 11. As for the use of the fixing end 122, this application does not limit it here. Optionally, other structural parts can also be arranged in the bracket 12, which will not be described in detail in this embodiment.

[0041] The power adapter 1 provided in this embodiment omits the upper cover for covering and opening the pin 11 in the power adapter 1 of the prior art, and instead adds a sleeve 20. The sleeve 20 is an annular structure, and both opposite ends thereof are hollow, so the sleeve 20 can be sleeved on the bracket 12, that is, the sleeve 20 can be sleeved on the outer periphery of the bracket 12. And the sleeve 20 is slidably connected to the bracket 12, that is, the sleeve 20 can slide relative to the bracket 12. If the fixed end 122 of the bracket 12 is used as a reference, the sleeve 20 can slide in a direction close to or away from the fixed end 122. The sliding direction is as follows: Figure 2 The direction shown by D1.

[0042] In addition, the closed state and open state of the power adapter 1 mentioned above can also be understood by the movement state and position of the sleeve 20. When the sleeve 20 slides in the direction away from the fixed end 122 and the distance from the fixed end 122 is the largest, it can be understood as a closed state. When the sleeve 20 slides in the direction close to the fixed end 122 and the distance from the fixed end 122 is the smallest, it can be understood as an open state. When the power adapter is in the open state, at least part of the pin 11 protrudes from the sleeve 20, so that the pin 11 can be inserted into the socket 3 for use.

[0043] As for how the sleeve 20 is sleeved and slidably connected to the bracket 12, this application will describe it in detail later.

[0044] In addition to the sleeve 20, the power adapter 1 provided in this embodiment also has a moving part 30. The moving part 30 is a movable component. The moving part 30 includes a first end 31, and the first end 31 is arranged on the side of the sleeve 20 away from the fixed end 122, that is, the first end 31 is arranged on at least a portion of the surface of the side of the sleeve 20 away from the fixed end 122. As for the positional relationship between the other parts of the moving part 30 and the pin assembly 10 and the sleeve 20, this application does not limit it here, and will be described in detail later. This embodiment only needs to make the first end 31 arranged on the side of the sleeve 20 away from the fixed end 122.

[0045] Optionally, the first end 31 may abut against the side of the sleeve 20 away from the fixed end 122, so that there is no gap between the first end 31 and the side of the sleeve 20 away from the fixed end 122, thereby improving the appearance performance of the power adapter 1. Of course, in other embodiments, there may also be a gap between the first end 31 and the side of the sleeve 20 away from the fixed end 122.

[0046] As can be seen from the above, in the related art, the power adapter 1 includes an adapter body 60, a cover body, and a pin assembly 10. The cover body can be rotated relative to the bracket 12, so that the power adapter 1 has a closed state and an open state. However, when the cover body is in a semi-open state, and the cover body has begun to rotate but has not yet rotated to the right position, the cover body has not yet abutted against the adapter body 60. At this time, in order to facilitate rotation, there is usually a gap between the cover body and the adapter body 60. At this time, when the user touches the surface of the adapter body 60 that has been inserted into the socket 3, especially the surface of the adapter body 60 near the pin 11, the creepage distance of the power adapter 1 is very short. Among them, the creepage distance refers to the length of the path that the current travels from the side of the pin 11 close to the adapter body 60 to the user's touch position on the outer surface of the adapter body 60. This distance is too small, usually only 1-2mm, which is much smaller than the preset safety distance, which will cause harm to the user.

[0047] Therefore, the present embodiment adds a sleeve 20 and a moving member 30, and the sleeve 20 can slide relative to the bracket 12, and the sliding of the sleeve 20 can also drive the moving member 30 to move. Specifically, when the power adapter 1 is in the process of changing from the closed state to the open state, the sleeve 20 slides toward the direction close to the fixed end 122 (such as Figure 4 The first end 31 is moved away from the pin 11, and the first end 31 is protruded from the sleeve 20. That is, the sleeve 20 can make the first end 31 of the movable member 30 open outward while sliding, thereby increasing the distance between the surface of the first end 31 away from the pin 11 and the pin 11. It can also be understood that the distance from the edge of the pin 11 close to the first end 31 to the surface of the first end 31 away from the pin 11 is increased (as shown in the D2 direction in FIG. Figure 5 L1 is indicated by a thick black line).

[0048] In this way, when the user touches the surface of the first end 31 away from the pin 11, the creepage distance can be increased (for example, the creepage distance is 6.7mm), which is greater than the preset safety distance (for example, 6.5mm), thereby improving the safety performance of the power adapter 1 and preventing the pin 11 from leaking electricity when inserted into the socket 3, thereby causing harm to the user. When the user touches the surface of the sleeve 20 away from the pin assembly 10, the current also needs to flow from the edge of the pin 11 to the bracket 12, then from the bracket 12 to the sleeve 20, and finally to the surface of the sleeve 20 away from the pin assembly 10 (for example, Figure 5 The black thick line L2 in FIG. 1 is equivalent to making the current not go in a straight line but go in multiple bends, thereby increasing the creepage distance (for example, the creepage distance is 6.52 mm), which is also greater than the preset safety distance (for example, 6.5 mm), improving the safety performance of the power adapter 1, and preventing the pin 11 from leaking when it is inserted into the socket 3.

[0049] In summary, the power adapter 1 provided in this embodiment is flat and compact in size when in the closed state, and is easy to carry. When used in the open state, it can meet the requirements of safety regulations and prevent leakage problems.

[0050] In addition, as to how the sliding of the sleeve 20 drives the moving member 30 to move and causes the first end 31 to move in a direction away from the pin 11 , this application will describe it in detail below.

[0051] In addition, this embodiment introduces that when the power adapter 1 is in the process of changing from the closed state to the open state, the first end 31 protrudes from the sleeve 20. That is, when the power adapter 1 is in the open state, the first end 31 protrudes from the sleeve 20 (such as Figure 4-Figure 5As shown). However, when the power adapter 1 is in a closed state, the positional relationship between the first end 31 and the sleeve 20 is not limited. For example, the surface of the first end 31 facing away from the pin 11 may be lower than the surface of the sleeve 20 facing away from the pin 11, or flush with the surface of the sleeve 20 facing away from the pin 11, or protrude from the surface of the sleeve 20 facing away from the pin 11. This embodiment is illustrated by the surface of the first end 31 facing away from the pin 11 being flush with the surface of the sleeve 20 facing away from the pin 11 (as shown in FIG. Figure 2 As shown), the flatness of the surface of the power adapter 1 is improved.

[0052] Please refer to Figure 6-Figure 8 , Figure 6 In one embodiment of the present application Figure 2 Cross-sectional view along direction BB. Figure 7 This is a cross-sectional view of a power adapter from a closed state to an open state in one embodiment of the present application. Figure 8 This is a cross-sectional view of the power adapter in an open state in one embodiment of the present application. In this embodiment, the connecting end 121 is provided with a sliding groove 13, and the moving member 30 further includes a second end 32 disposed opposite to the first end 31, and the second end 32 is disposed in the sliding groove 13;

[0053] When the power adapter 1 moves from the closed state to the open state, the sleeve 20 slides toward the fixed end 122, driving the second end 32 to slide in the sliding groove 13 toward the fixed end 122, and the second end 32 cooperates with the side wall of the sliding groove 13 to move the first end 31 in the direction away from the pin 11.

[0054] In this embodiment, the moving member 30 includes not only the first end 31 but also the second end 32 which is arranged opposite to the first end 31. The connecting end 121 of the bracket 12 may be provided with a sliding groove 13, and the second end 32 is arranged in the sliding groove 13. That is, the sliding groove 13 is used to install part of the moving member 30, and the sliding member is also used to interact with the second end 32 of the sliding member.

[0055] Specifically, when the power adapter 1 is in the process of changing from the closed state to the open state, the sleeve 20 will slide in the direction close to the fixed end 122. At this time, the sliding of the sleeve 20 can make the moving member 30 also slide in the direction close to the fixed end 122, so that the second end 32 can also slide in the sliding groove 13 in the direction close to the fixed end 122. When sliding, the second end 32 can cooperate with the side wall of the sliding groove 13 to move the first end 31 in the direction away from the pin 11.

[0056] The above content can be simply understood as follows: the sliding of the sleeve 20 drives the sliding of the second end 32 , and the second end 32 can cooperate with the side wall of the sliding groove 13 when sliding to move the first end 31 outward, thereby achieving the purpose of increasing the creepage distance.

[0057] As to how the sliding of the sleeve 20 drives the second end 32 of the moving member 30 to slide, and how the second end 32 cooperates with the side wall of the sliding groove 13 to move the first end 31 outward, the present application will describe in detail below.

[0058] Please refer to Figure 8-Figure 9 , Fig. 9 The figure is a cross-sectional exploded view of the bracket and the moving part in one embodiment of the present application. In this embodiment, the side wall of the sliding groove 13 has a first inclined surface 131 on the side away from the fixed end 122, and the side of the second end 32 close to the fixed end 122 has a second inclined surface 322. When the power adapter 1 is in the process of changing from the closed state to the open state, the second inclined surface 322 abuts against the first inclined surface 131, and the component force of the second inclined surface 322 on the first inclined surface 131 causes the second end 32 to slide in the direction close to the fixed end 122, and the component force can also cause the first end 31 to move in the direction away from the pin 11.

[0059] In this embodiment, it will be described in detail how the second end 32 cooperates with the side wall of the sliding groove 13 to move the first end 31 outward. In this embodiment, a first inclined surface 131 can be provided on the side of the side wall of the sliding groove 13 away from the fixed end 122, and a second inclined surface 322 can be provided on the side of the second end 32 close to the fixed end 122.

[0060] Optionally, the first inclined surface 131 is arranged so that the opening size of the part of the sliding groove 13 gradually decreases from the side away from the fixed end 122 to the side close to the fixed end 122, that is, the part of the sliding groove 13 where the first inclined surface 131 is arranged is a "large at the top and small at the bottom". And the first inclined surface 131 is arranged toward the first end 31, that is, the vertical distance from the first inclined surface 131 away from the fixed end 122 to the first end 31 is greater than the vertical distance from the first inclined surface 131 close to the fixed end 122 to the first end 31.

[0061] The second inclined surface 322 may be arranged parallel to the first inclined surface 131 , so that the second inclined surface 322 and the first inclined surface 131 can be in better contact.

[0062] By setting the first inclined surface 131 and the second inclined surface 322, when the power adapter 1 is in the process of changing from the closed state to the open state, the sleeve 20 will slide in the direction close to the fixed end 122. At this time, the sliding of the sleeve 20 can make the moving member 30 also slide in the direction close to the fixed end 122, so that the second end 32 can also slide in the sliding groove 13 in the direction close to the fixed end 122. The sliding of the second end 32 can make the second inclined surface 322 abut against the first inclined surface 131.

[0063] When the second inclined surface 322 abuts against the first inclined surface 131, the moving member 30 applies a moving force F toward the fixed end 122 and parallel to the sliding direction of the sleeve 20 to the first inclined surface 131 through the second inclined surface 322. The moving force F on the first inclined surface 131 can be decomposed into a positive pressure N perpendicular to the first inclined surface 131 and toward the fixed end 122, and a sliding force F1 parallel to the first inclined surface 131 and toward the fixed end 122.

[0064] And because the first inclined surface 131 is configured as described above, the second end 32 will slide on the first inclined surface 131 in a direction close to the fixed end 122 while sliding in a direction away from the plug pin 11. Therefore, the movement of the second end 32 can drive the first end 31 to move together, so that the first end 31 also slides in a direction close to the fixed end 122 while sliding in a direction away from the plug pin 11, so that the first end 31 and the sleeve 20 are relatively stationary in the sliding direction, but the first end 31 moves in a direction away from the plug pin 11, and finally the first end 31 protrudes from the sleeve 20, thereby increasing the creepage distance.

[0065] In addition, when the power adapter 1 is in the closed state, the first inclined surface 131 can abut against the second inclined surface 322, or there is a gap between the first inclined surface 131 and the second inclined surface 322. This embodiment is illustrated by the first inclined surface 131 abutting against the second inclined surface 322.

[0066] Please refer to Fig.10 , Fig.10 1 is a schematic diagram of an exploded view of a power adapter in an embodiment of the present application. In this embodiment, the power adapter 1 further includes a cover plate 40, which is disposed on a side of the sleeve 20 away from the fixed end 122, and the cover plate 40 is provided with a through hole 41, the pin 11 passes through the through hole 41, and the cover plate 40 is disposed on the sleeve 20 and the moving member 30.

[0067] In this embodiment, it will be described in detail how the sliding of the sleeve 20 drives the second end 32 of the movable member 30 to slide. In this embodiment, a cover plate 40 can be added, and a through hole 41 can be opened on the cover plate 40. The cover plate 40 is arranged on the side of the sleeve 20 away from the fixed end 122, and the pin 11 passes through the through hole 41, and the cover plate 40 is covered on the sleeve 20 and the movable member 30. In this way, the cover plate 40 is covered on the sleeve 20, firstly, the structure inside the sleeve 20 can be shielded, so that the user cannot see the structure inside the sleeve 20, and the sealing performance can be improved. Secondly, the sleeve 20 and the cover plate 40 can be surrounded to form an accommodating space 42, and the accommodating space 42 can hide at least part of the pin 11.

[0068] When the power adapter 1 is in the closed state, the pins 11 can be completely accommodated in the accommodating space 42, or only part of the pins 11 can be outside the accommodating space 42, thereby effectively protecting the pins 11 from damage. When the power adapter 1 is in the process of changing from the closed state to the open state, the sleeve 20 continuously slides toward the direction close to the fixed end 122, so that the pins 11 continuously protrude from the accommodating space 42. When the power adapter 1 is in the open state, the size of the pins 11 protruding from the accommodating space 42 reaches the maximum, and can be plugged into the socket 3.

[0069] In addition, since the cover plate 40 also covers the moving part 30, when the power adapter 1 is changed from the closed state to the open state, the sleeve 20 slides toward the direction close to the fixed end 122, so that the cover plate 40 also slides toward the direction close to the fixed end 122, and the cover plate 40 can abut the moving part 30. The movement of the cover plate 40 can drive the moving part 30 to slide toward the direction close to the fixed end 122, so that the second end 32 also slides in the sliding groove 13 toward the direction close to the fixed end 122, and the second end 32 cooperates with the side wall of the sliding groove 13 to make the first end 31 move in the direction away from the pin 11, and finally the first end 31 protrudes from the sleeve 20, thereby increasing the creepage distance.

[0070] In summary, the closed state and the open state of the power adapter 1 can be described in many aspects, such as the sliding of the sleeve 20 , the relationship between the pin 11 and the sleeve 20 , or the relationship between the moving part 30 and the sleeve 20 .

[0071] In addition, when the power adapter 1 is in the closed state, the cover 40 may abut against the moving member 30 , or there may be a gap between the cover 40 and the moving member 30 .

[0072] In addition, when the power adapter 1 is in a closed state, the cover plate 40 can be used as the plug-in surface of the power adapter 1. In this case, the thickness of the power adapter 1 can be greatly reduced, making the power adapter 1 easy to carry. When the power adapter 1 is in an open state, since the first end 31 of the moving part 30 protrudes from the sleeve 20, the creepage distance is increased, thereby improving the safety performance of the power adapter 1. At this time, the cover plate 40 and the surface protruding from the first end 31 of the sleeve 20 and away from the fixed end 122 together constitute the plug-in surface.

[0073] Please refer to Fig.11 , Fig.11 Schematic diagram of a part of the structure of the power adapter in one embodiment of the present application. In this embodiment, the moving member 30 includes a first sub-moving member 33 and a second sub-moving member 34, and the first ends 31 of the first sub-moving member 33 and the second sub-moving member 34 are respectively arranged on opposite sides of the sleeve 20;

[0074] The power adapter 1 also includes a first magnetic component 51 and a second magnetic component 52, wherein the first magnetic component 51 is disposed in the first sub-movable component 33, and the second magnetic component 52 is disposed in the second sub-movable component 34; the first magnetic component 51 and the second magnetic component 52 attract each other so that the first sub-movable component 33 can be magnetically connected to the second sub-movable component 34.

[0075] In this embodiment, the moving member 30 may include two sub-moving members 30, namely a first sub-moving member 33 and a second sub-moving member 34. And the first ends 31 of the first sub-moving member 33 and the second sub-moving member 34 are respectively arranged on opposite sides of the sleeve 20. In this way, the first ends 31 on the opposite sides can both protrude from the sleeve 20, further improving the safety performance of the power adapter 1.

[0076] In addition, the power adapter 1 can also be provided with a first magnetic member 51 and a second magnetic member 52, and the first magnetic member 51 is disposed in the first sub-moving member 33, and the second magnetic member 52 is disposed in the second sub-moving member 34. The first magnetic member 51 and the second magnetic member 52 are attracted to each other by opposite charges so that the first sub-moving member 33 can be magnetically connected to the second sub-moving member 34.

[0077] As can be seen from the above, the first magnetic member 51 and the second magnetic member 52 have multiple uses. First, the first magnetic member 51 and the second magnetic member 52 can enable the first sub-moving member 33 to be magnetically connected to the second sub-moving member 34. For example, when the power adapter 1 is in the closed state, the first magnetic member 51 and the second magnetic member 52 attract each other, so that the first sub-moving member 33 is connected to the second sub-moving member 34.

[0078] Secondly, the magnetic force between the first magnetic member 51 and the second magnetic member 52 can prevent the moving member 30 from falling. Figure 11-Figure 15 , Fig.12 This is a schematic cross-sectional exploded view of a bracket and a moving part in another embodiment of the present application. Fig.13 In one embodiment of the present application, when the power adapter is in the turned-on state, Figure 4 Schematic diagram of the cross section along the CC direction. Fig.14 This is a cross-sectional view of a power adapter from an open state to a closed state in one embodiment of the present application. Fig.15 This is a cross-sectional view of a power adapter in a closed state in one embodiment of the present application. In this embodiment, when the power adapter 1 is in the closed state, the magnetic attraction of the first magnetic member 51 and the second magnetic member 52 causes the first inclined surface 131 to abut against the second inclined surface 322, so that the movable member 30 is stationary relative to the bracket 12; when the power adapter 1 is in the process of changing from the open state to the closed state, the first magnetic member 51 and the second magnetic member 52 cooperate with each other to move the first end 31 of the first sub-movable member 33 and the second sub-movable member 34 toward the direction close to the pin 11.

[0079] When the power adapter 1 is in the closed state, the sleeve 20, the moving member 30, and even the cover 40 will move downward spontaneously due to the effect of gravity, so that the first inclined surface 131 abuts against the second inclined surface 322. At this time, due to the attraction between the first magnetic member 51 and the second magnetic member 52, the magnetic force F' between the first magnetic member 51 and the second magnetic member 52 will be applied to the first inclined surface 131 through the second inclined surface 322 of the moving member 30. At this time, the component force of the magnetic force F' on the second inclined surface 322 can make the moving member 30 stationary relative to the bracket 12.

[0080] For example, the magnetic force F' on the second inclined surface 322 can be decomposed into a positive pressure N perpendicular to the first inclined surface 131 and toward the fixed end 122, and a sliding force F2 parallel to the first inclined surface 131 and away from the fixed end 122. Therefore, the existence of the magnetic force can increase the friction force of the moving member 30 on the second inclined surface 322, so that the moving member 30 is stationary relative to the bracket 12, thereby preventing the problem of the moving member 30 and the sleeve 20 falling off when the power adapter 1 is in the closed state.

[0081] Again, the cooperation between the first magnetic part 51 and the second magnetic part 52 can also make the first magnetic part 51 and the second magnetic part 52 approach each other through magnetic attraction when the power adapter 1 moves from the open state to the closed state, thereby causing the first end 31 of the first sub-movable part 33 and the second sub-movable part 34 to move toward the direction close to the pin 11.

[0082] In summary, the arrangement of the first magnetic member 51 and the second magnetic member 52 can ensure the tight connection between the two sub-moving members 30 in the closed state; can also ensure the stability of the moving member 30 and prevent the moving member 30 from falling; and can also restore the two sub-moving members 30.

[0083] Please refer to Fig.16 , Fig.16 Schematic diagram of partial structural decomposition of a power adapter in one embodiment of the present application. In this embodiment, a first receiving groove 35 is provided on the side of the first sub-moving member 33 away from the fixed end 122, and the first magnetic member 51 is disposed in the first receiving groove 35; a second receiving groove 36 is provided on the side of the second sub-moving member 34 away from the fixed end 122, and the second magnetic member 52 is disposed in the second receiving groove 36.

[0084] In this embodiment, a first receiving groove 35 may be provided on a side of the first sub-moving member 33 away from the fixed end 122, and then the first magnetic member 51 is disposed in the first receiving groove 35. A second receiving groove 36 may also be provided on a side of the second sub-moving member 34 away from the fixed end 122, and then the second magnetic member 52 is disposed in the second receiving groove 36. This reduces the difficulty of assembling the first magnetic member 51 and the second magnetic member 52.

[0085] Please refer again Figure 2 In this embodiment, a receiving groove 21 is provided on a side of the sleeve 20 away from the fixed end 122 , and the first end 31 is disposed in the receiving groove 21 .

[0086] In this embodiment, a receiving groove 21 may be provided on a side of the sleeve 20 away from the fixed end 122, and the first end 31 is provided in the receiving groove 21. This can reduce the difficulty of assembling the moving member 30 on the sleeve 20. In addition, the receiving groove 21 can also be used to limit the first end 31 of the moving member 30.

[0087] Please refer to Fig.17 , Fig.17 The cross-sectional diagram of the pin assembly and the sleeve in one embodiment of the present application is shown in FIG. In this embodiment, the inner peripheral side wall of the sleeve 20 is provided with a first sliding portion 22, and the outer peripheral side wall of the bracket 12 is provided with a second sliding portion 14, and the first sliding portion 22 and the second sliding portion 14 cooperate with each other so that the sleeve 20 can slide in a direction close to or away from the fixed end 122.

[0088] In this embodiment, a first sliding portion 22 may be provided on the inner side wall of the sleeve 20, and a second sliding portion 14 may be provided on the outer side wall of the bracket 12, and the first sliding portion 22 and the second sliding portion 14 may cooperate with each other to realize the sliding of the sleeve 20 mentioned in the above embodiment.

[0089] Optionally, the first sliding part 22 may be a slider or a slide groove, and the second sliding part 14 may be a slide groove or a slider. When the first sliding part 22 is a slider, the second sliding part 14 may be a slide groove. When the first sliding part 22 is a slide groove, the second sliding part 14 may be a slider. In this embodiment, the first sliding part 22 is a slider, and the second sliding part 14 may be a slide groove for illustration.

[0090] Please refer again Fig.17 In this embodiment, a first stop portion 23 is provided on the inner side wall of the sleeve 20, and a second stop portion 15 is provided on the outer side wall of the bracket 12 away from the fixed end 122. The first stop portion 23 and the second stop portion 15 cooperate with each other to limit the sleeve 20.

[0091] In this embodiment, a first stop portion 23 may be provided on the inner peripheral side wall of the sleeve 20, and a second stop portion 15 may be provided on the outer peripheral side wall of the bracket 12 away from the fixed end 122. The first stop portion 23 and the second stop portion 15 cooperate with each other to limit the sleeve 20. This prevents the sleeve 20 from sliding when sliding in a direction away from the fixed end 122, thereby preventing the sleeve 20 from separating from the bracket 12.

[0092] Please refer to Figure 18-19 , Fig.18 The figure is a schematic diagram of the three-dimensional structure of a power adapter in one embodiment of the present application. Fig.19 for Fig.18 In this embodiment, the power adapter 1 further includes an adapter body 60, the adapter body 60 has a receiving space 61, the fixed end 122 is disposed in the receiving space 61, and the sleeve 20 can abut against the surface of the adapter body 60 that opens the receiving space 61 to limit the sleeve 20.

[0093] The power adapter 1 provided in this embodiment may also include an adapter body 60. The adapter body 60 may be understood as the lower cover of the power adapter 1, which is used to protect and install the structural parts of the power adapter 1. For example, various structural parts (such as circuit boards) may be arranged in the receiving space 61 of the adapter body 60. And the receiving space 61 is formed by the side walls of the adapter body 60. For example, the side walls of the adapter body 60 are arranged around to enclose the receiving space 61. However, as to whether the adapter body 60 has a bottom wall, this application does not limit it.

[0094] In this embodiment, the fixed end 122 can also be disposed in the receiving space 61, that is, part of the bracket 12 is disposed in the receiving space 61, and connected to the side wall of the adapter body 60, so that the bracket 12 is fixed to the adapter body 60. And because the fixed end 122 is disposed in the receiving space 61, that is, the side wall of the adapter body 60 protrudes from the bracket 12, the surface of the adapter body 60 that opens the receiving space 61 can be used to limit the sleeve 20. That is, when the sleeve 20 slides toward the direction close to the fixed end 122, and the sleeve 20 abuts against the surface of the adapter body 60 that opens the receiving space 61, the sleeve 20 cannot continue to slide, thereby achieving the dual effects of assembly and limiting.

[0095] In summary, the present application can utilize the stop portion and the adapter body 60 to limit the position of the sleeve 20 in two sliding directions, thereby achieving the purpose of limiting.
