When the power adapter 3 is in a closed state, the flip cover 20 is closed on the adapter body 10 , and the pins 110 are received in the housing 120 and/or the flip cover 20 . When the power adapter 3 is in an open state, the flip cover 20 is turned over to expose the adapter body 10 , the pins 110 are exposed outside the through holes R1 of the first surface X1 , and the first surface X1 It forms the plug-in surface of the power adapter 3 .

The above-mentioned components will be introduced in detail below with reference to the accompanying drawings.

Please refer to FIG. 2 . The adapter body 10 includes pins 110 and a shell 120 . The pins 110 are directly or indirectly carried by the shell 120 .

The material of the pin 110 may be metal, such as copper alloy, aluminum alloy, etc. The pins 110 may be in the shape of, but are not limited to, strips. The end of the pin 110 for inserting into the socket 4 is arc-shaped to facilitate the insertion of the pin 110 into the socket 4 . The number of the pins 110 may be, but is not limited to, two, three, etc. This application only uses two oppositely arranged pins 110 for illustration.

Please refer to FIG. 5 . The so-called adapter body 10 refers to the part that implements the voltage conversion function of the power adapter 3 . The adapter body 10 may also generally include a circuit board 130 and an output port 140 . The circuit board 130 and the output port 140 are at least partially housed in the housing 120 . Among them, the circuit board 130 is electrically connected to the pin 110, and the circuit board 130 is used to implement voltage conversion. The output port 140 is electrically connected to the circuit board 130 , and is used to electrically connect to the electronic device 2 through the cable 5 to transmit power to the electronic device 2 . The output port 140 may be a USB interface or a Type-C interface. It should be noted that the output port 140 can be disposed at the bottom of the adapter body 10 , that is, at an end of the adapter body 10 away from the pins 110 . Of course, in other embodiments, the output port 140 can also be disposed at the adapter body. 10 other positions, such as the side.

The flip cover 20 is movably connected to the housing 120 so that the power adapter 3 has an open state (as shown in Figure 2) and a closed state (as shown in Figures 3 and 4). That is to say, the flip cover 20 can move relative to the housing 120, so that the power adapter 3 can assume two different states: a closed state and an open state. It should be noted that the movable connection form of the flip cover 20 and the housing 120 may be, but is not limited to, a rotational connection.

The flip cover 20 has a first surface X1 (as shown in Figure 2) and a second surface X2 (as shown in Figure 4) arranged oppositely, and a third surface X3 (as shown in Figure 4) located between the first surface X1 and the second surface X2. 3). The flip cover 20 has a through hole R1 located on the first surface X1 (see Figures 2 and 3).

Please refer to Figure 3. When the power adapter 3 is in a closed state, the third surface X3 is away from the housing 120, the flip cover 20 is closed on the adapter body 10, and the pins 110 are received in the housing. body 120 and/or the flip cover 20 . That is to say, the closed state is a state in which the pin 110 is received in the housing 120 and/or the flip cover 20 . Specifically, in the first embodiment, the pins 110 are retractable relative to the housing 120. When the power adapter 3 is switched from the open state to the closed state, the pins 110 are retracted into the housing 120, so that they are all accommodated in the housing 120. inside the housing 120. When the power adapter 3 is switched from the closed state to the open state, the pins 110 protrude from the housing 120 . In the second embodiment, the pins 110 are fixedly carried on the housing 120 and cannot be retracted. At least part of the pins 110 is always exposed outside the housing 120. When the power adapter 3 is in a closed state, the pins 110 are exposed outside the housing 120. 110 is contained within the flip cover 20 . It should be noted that the following content of this application is mainly exemplified by the second embodiment (at least part of the pins 110 is always exposed outside the housing 120 ), and related structural settings such as the flip cover 20 and the housing 120 can also be applied to the same application. First implementation.

Referring to FIG. 2 , when the power adapter 3 is in an open state, the flip cover 20 is turned over to expose the adapter body 10 , the first surface X1 is away from the housing 120 , and the pins 110 are exposed on the The first surface X1 is outside the through hole R1 , and the first surface X1 constitutes the plug-in surface of the power adapter 3 . That is to say, the open state is an exposed state in which the pins 110 are exposed to the outside world. Specifically, when the power adapter 3 is switched from the closed state to the open state, the surface of the flip cover 20 facing away from the housing 120 changes from the third surface X3 to the third surface X3. There is a surface X1, and the pins 110 protrude from the through holes R1 on the first surface X1, and the first surface X1 therefore serves as the insertion surface.

The insertion surface refers to the upper surface of the power adapter 3 facing the socket 4, or adjacent to the socket 4, or attached to the outer surface of the socket 4 when the pins 110 of the power adapter 3 are inserted into the socket 4. For the power adapter 3, when the power adapter 3 is plugged into the socket 4, in order to prevent the power of the socket 4 from leaking through the pins 110 and causing harm to the user. Therefore, the above-mentioned plug surface meets the safety regulations (safety requirements) of the power adapter 3. That is to say, the distance from the edge of the pin 110 to the edge of the plug surface is greater than or equal to the safety distance (or safety distance). The safety distance may be, but is not limited to, 5.1 mm, 6.3 mm, 6.5 mm, 7.9 mm, etc. The safety distance may be different for different regions or countries, and this application does not limit this.

Compared with the prior art, the flip cover 20 in the power adapter 3 provided by this application is movably connected to the housing 120, so that the power adapter 3 has a closed state and an open state. When the power adapter 3 needs to be used to supply power to the electronic device 2, The power adapter 3 can be switched to the open state, so that the pins 110 are exposed from the through holes R1 on the flip cover 20 , and then the exposed pins 110 are plugged into the socket 4 to achieve charging. When the power adapter 3 is not needed, the power adapter 3 can be switched to the off state so that the pins 110 are contained in the housing 120 or the flip cover 20 to avoid damage to the pins 110, such as impact deformation and functional failure due to bending. and other risks, thereby extending the service life of the power adapter 3.

Referring to FIGS. 2 to 4 , the housing 120 has a first side Y1 (as shown in FIGS. 2 and 3 ) and a second side Y2 (as shown in FIG. 4 ) arranged oppositely. When the power adapter 3 is in a closed state, the first side Y1 and the first surface X1 are located on the same side of the power adapter 3 , and the second side Y2 and the second surface X2 are located on the same side. The same side of the power adapter 3. When the power adapter 3 is in an open state, two opposite ends of the first surface X1 protrude from the first side Y1 and the second side Y2 respectively.

In this embodiment, when the power adapter 3 is in the open state, since the first surface X1 as the plug surface protrudes from the first side Y1 and the second side Y2 at the same time, and the first surface X1 is located on the flip cover 20, therefore For the adapter body 10 , the size design of the adapter body 10 will not be limited by safety requirements, so that the maximum distance between the first side Y1 and the second side Y2 (the thickness of the adapter body 10 ) can be designed. as small as possible. For the flip cover 20, when the power adapter 3 is in the open state, the first surface X1 on the flip cover 20 serves as the plug-in surface. Therefore, only the size of the first surface The maximum distance between the first surface X1 and the second surface X2 (thickness of the flip cover 20 ) is designed to be as small as possible. To sum up, the thickness of the adapter body 10 and the flip cover 20 will not be restricted by safety regulations. In other words, the overall thickness of the power adapter 3 can be set as small as possible to meet the user's thinning needs.

In the related art, a single flip cover solution and a double flip cover solution are usually used to reduce the thickness of the power adapter.

For the single flip cover solution: the power adapter includes an adapter body and a flip cover, and the flip cover is rotationally connected to the adapter body. The adapter body has a first end face, and the pins pass through the first end face and are exposed to the outside world. The flip cover has a second end surface. The thickness of the power adapter is the largest of the width H1 of the first end surface and the width H2 of the second end surface. When the power adapter is in a closed state, the first end face and the second end face face each other. When the power adapter is switched from the closed state to the open state, the flip cover is rotated to one side of the adapter body (rotated 180°). After the flip cover is rotated, the first end face and the second end face are in the same plane, and the first end face and the second end face are separated from each other. Together they form the mating surface. It can be understood that since the insertion surface is composed of the first end surface and the second end surface, and the insertion surface needs to meet safety regulations, the width of the first end surface and the second end surface cannot be set to be very small at the same time, so that As a result, the thickness of the power adapter cannot be designed as small as possible.

For the double flip cover solution: the power adapter includes an adapter body and two flip covers. The two flip covers are oppositely arranged and both are rotationally connected to the adapter body. The adapter body has a first end face, and the pins pass through the first end face and are exposed to the outside world. One of the two flip covers has a second end surface and the other has a third end surface. The thickness of the power adapter is the largest of the width H1 of the first end surface and the sum of the widths H2 of the second end surface and the third end surface. When the power adapter is in a closed state, both the second end surface and the third end surface face the first end surface. When the power adapter is switched from the closed state to the open state, the two flip covers are rotated to opposite sides of the adapter body (the two flip covers are rotated 180° in opposite directions). After the flip covers are rotated, the first end face, the second end face, The third end surface is on the same plane, and the three end surfaces together form the insertion surface. Similar to the above single flip solution, in the double flip solution, since the plug surface is composed of the first end face, the second end face, and the third end face, and the plug face needs to meet the safety requirements, therefore, the first end face, the third end face The widths of the second end surface and the third end surface cannot be set to be very small at the same time, so that the thickness of the power adapter cannot be designed to be as small as possible. Moreover, in the double flip solution, each flip is rotatably connected to the adapter body, so there are two rotary connection mechanisms. To ensure the strength of the rotary connection structure, the size of the structure needs to be increased, which will increase the thickness of the power adapter. ; On the contrary, if you want to ensure that the thickness of the power adapter is small, the strength of the rotating connection structure will be weakened. Therefore, there is a design conflict between strength and thickness in the double flip solution.

Compared with the single flip cover solution and the double flip cover solution mentioned above, the thickness of the power adapter 3 provided by this application is the distance between the first side Y1 and the second side Y2, or the thickness between the first surface X1 and the second surface X2. However, these two distances are not affected by safety requirements. Only the size of the first surface And the double flip solution can be set to a smaller thickness. In addition, in this application, only one flip cover 20 is required, thereby avoiding the design conflict between strength and thickness existing in the above-mentioned double flip cover 20 solution.

Optionally, the first surface X1 and the first side Y1 are flush. The second surface X2 is flush with the second side Y2.

Please refer to FIG. 6 . It should be noted that the distance d1 from the left edge of the pin 110 to the left edge of the first surface X1 is greater than or equal to the safety distance. The distance d2 from the right edge of the pin 110 to the right edge of the first surface X1 is greater than or equal to the safety distance.

Please refer to Figures 2, 3 and 7. The flip cover 20 includes a connected cover plate 210 and a main cover body 220. The cover 210 is made of insulating material, such as plastic, rubber, ceramics, glass, etc. The cover 210 has the first surface X1, the main cover 220 has the second surface X2, and the cover 210 is connected to a side of the main cover 220 that is away from the second surface X2. side. The main cover 220 is rotatably connected to the housing 120 . The main cover 220 has a receiving space R2 connected to the through hole R1 . When the power adapter 3 is in a closed state, the pins 110 are located in the receiving space R2. It should be noted that in this embodiment, the pins 110 and the housing 120 are relatively fixed, and at least part of the pins 110 are located outside the housing 120 .

Specifically, when the power adapter 3 is in an open state, the pins 110 pass through the through holes R1 on the cover 210 and are exposed to the outside world. In this state, the socket 4 can be inserted. When the power adapter 3 is not in use, the flip cover 20 can be rotated in the opposite direction (to rotate the second surface X2 away from the second side Y2), so that the pins 110 gradually enter the receiving space R2 of the main cover 220 through the through hole R1. , the power adapter 3 thereby switches from the open state to the closed state. When the power adapter 3 is switched to the off state, since the pin 110 is located in the receiving space R2, the pin 110 can be protected from being damaged by foreign objects. In the same way, if you want to switch the power adapter 3 from the closed state to the open state, you only need to rotate the flip cover 20 in the forward direction (rotate the second surface X2 toward the direction closer to the second side Y2), and the pins 110 will gradually move out of the receiving space R2. Enter and pass through the through hole R1, and finally emerge to the outside world.

The cover plate 210 and the main cover body 220 may have an integrated structure or a split structure. The so-called integrated structure means that the cover plate 210 and the main cover body 220 are processed into one piece. The split structure means that the cover 210 and the main cover 220 are processed independently and then connected together to form the flip cover 20 . This application only uses a split structure as an example. In the split structure, the connection form between the cover plate 210 and the main cover body 220 can be, but is not limited to, bonding (glue bonding, double-sided tape bonding), connection using connectors (screws, etc.), buckle connection, etc.

Referring to FIG. 6 , the power adapter 3 further includes a shielding member 30 , and the shielding member 30 is made of insulating material, such as plastic, rubber, ceramics, glass, etc. The two opposite ends of the shielding member 30 are movably connected to the cover plate 210 and the adapter body 10 respectively, so that the shielding member 30 can move following the rotation of the cover plate 210 . When the power adapter 3 is in the open state, at least part of the shielding member 30 is located on the side of the housing 120 with the first side Y1 , and the shielding member 30 blocks the cover 210 and the housing. The junction of body 120 J.

It can be understood that during the process of inserting the open power adapter 3 into the socket 4, the user's fingers need to be close to the first side Y1 and the second side Y2 of the housing 120 at the same time in order to provide the power adapter 3 with the function of being inserted into the socket 4. force. However, there is resistance during the insertion process, so during this process, the finger attached to the first side Y1 may slide along the first side Y1 toward the position of the cover 210 , and the cover 210 is protruding from the first side. The status of side Y1. If the above-mentioned shielding member 30 is not provided, the fingers attached to the first side Y1 may reach the junction J of the cover 210 and the casing 120 and abut against the cover 210 . This abutment causes the cover 210 and the casing 120 to A large gap is created, and the finger extends into the gap and touches the pin 110, eventually causing an electric shock accident.

Therefore, the shielding member 30 provided in this embodiment is to enable the shielding member 30 to cover or cover the junction J. Even if the finger attached to the first side Y1 slides toward the cover 210, it will eventually be affected by the shielding member 30. blocking, thereby preventing fingers from reaching the junction J and touching the pin 110. Furthermore, since the flip cover 20 can rotate relative to the housing 120, in this embodiment, the shielding member 30 is movably connected to the cover 210 and the adapter body 10, so that when the flip cover 20 rotates relative to the housing 120, the shielding member 30 It can produce the corresponding movement and at the same time, it will not hinder the movement of the flip cover 20 .

Several possible implementations of the shielding member 30 will be described in detail below with reference to the accompanying drawings.

In the first embodiment, the shielding member 30 is a rigid member, that is, the shielding member 30 will not deform or will not deform significantly during movement.

Please refer to Figures 8 to 11 and 12, wherein Figure 12 shows a schematic diagram when the flip cover is rotated 0°, 30°, 60°, and 90° relative to the housing. One end of the shielding member 30 is rotatably connected to an end of the cover plate 210 away from the third surface X3. An end of the shield 30 away from the cover 210 is slidably connected to the first side Y1 of the housing 120 and can slide in a direction toward or away from the pin 110 .

Specifically, in order to facilitate the explanation of the solution, it is defined here that the shielding member 30 has a first movable end and a second movable end that are opposite to each other. The first movable end is rotatably connected to the cover 210 , and the second movable end is slidably connected to the housing 120 . Please refer to FIGS. 8 , 9 , and 12 . When the power adapter 3 is in a closed state, the shield 30 is parallel or almost parallel to the first side Y1 of the housing 120 , and the second movable end is away from the pin 110 . Please refer to FIGS. 10 to 11 and 12 . When the power adapter 3 is in the open state, the shield 30 is inclined relative to the first side Y1 of the housing 120 and faces the above-mentioned junction J, and the second movable end is close to the pin 110 . When the power adapter 3 switches from the closed state to the open state, the first movable end follows the movement of the cover 210 and gradually moves away from the housing 120, while the second movable end moves closer to the pin 110, so that the shield 30 gradually tilts. When the power adapter 3 is switched from the open state to the closed state, the first movable end follows the movement of the cover 210 and gradually approaches the housing 120 , while the second movable end moves away from the pin 110 , and the inclination angle of the shield 30 is accordingly slowing shrieking.

Referring to FIG. 13 , the housing 120 has an accommodating groove S1 that is recessed from the first side Y1 toward the second side Y2 . When the power adapter 3 is in a closed state, the shielding member 30 is received in the accommodating slot S1. It can be understood that the accommodating groove S1 can play a role in limiting the shielding member 30. On the one hand, it can protect the shielding member 30 to a certain extent and prevent the shielding member 30 from being distorted under the action of external force and damaging the shielding member 30 and the cover plate 210. The connection structure; on the other hand, the power adapter 3 can also be made more beautiful.

Further, the first side Y1 includes a first sub-surface Y11 and a second sub-surface Y12, wherein the first sub-surface Y11 is further away from the second side Y2 than the second sub-surface Y12, and the second sub-surface Y11 is further away from the second side Y2 than the second sub-surface Y12. Y12 serves as the bottom wall of the accommodation tank S1. Optionally, when the power adapter 3 is in a closed state, the surface of the shielding member 30 away from the second side Y2 is flush with the first sub-surface Y11.

When the shielding member 30 is a rigid member, in the first sub-implementation: please refer to FIG. 14 , the housing 120 further has a slide groove S2 recessed from the side wall of the accommodating groove S1. An end of the shielding member 30 away from the cover 210 is at least partially located in the chute S2 and can slide in the chute S2 toward or away from the pin 110 .

Specifically, chute S2 is provided on two opposite side walls of the accommodating groove S1. The two chute S2 are arranged oppositely, and the extending direction of the chute S2 points toward the pin 110. The chute S2 is used to receive at least part of the shielding member 30 , thereby guiding the sliding direction of the shielding member 30 and limiting the position of the shielding member 30 to prevent the shielding member 30 from falling off the housing 120 .

Optionally, please refer to FIG. 15 . The end (the second movable end) of the shielding member 30 away from the cover 210 is provided with two protrusions 320 . The two protrusions 320 are respectively protruded on two opposite sides of the shielding member 30 . On the other side, each protruding portion 320 is disposed in the corresponding slide groove S2 and can slide in the slide groove S2. Further optionally, the outer surface of the protruding portion 320 is a cylindrical surface.

Optionally, please refer to Figure 16. The end (the second movable end) of the shielding member 30 away from the cover 210 is provided with a sliding rod 330. The sliding rod 330 is inserted into the shielding member 30 and protrudes from the opposite side of the shielding member 30. On both sides of the back, the portions of the two ends of the sliding rod 330 that protrude from the shielding member 30 are disposed in corresponding chute S2 and can slide in the chute S2. Further optionally, the outer surface of the sliding rod 330 is a cylindrical surface.

It should be noted that in the first sub-implementation, the length of the chute S2 in the extension direction is greater than or equal to the movement stroke of the second movable end of the shield 30 to ensure that the protruding portion 320 or the sliding rod located at the second movable end 330 will not fall out of the chute S2 during the sliding process. In other words, no matter whether the power adapter 3 is in an open state or a closed state, the protruding portion 320 or the sliding rod 330 located at the second movable end is always located in the slide slot S2.

When the shielding member 30 is a rigid member, in the second sub-implementation, please refer to FIG. 17 , the power adapter 3 further includes a traction member 40 and a first force-applying member 50 . Wherein, the first force-applying member 50 is provided in the flip cover 20 . One end of the pulling member 40 is connected to the first force applying member 50 , and the other end of the pulling member 40 is connected to an end (the second movable end) of the shielding member 30 away from the cover plate 210 . When the power adapter 3 is in the open state, the first force-applying member 50 tightens the pulling member 40 so that the shielding member 30 abuts against the pulling member 40 under the tightening effect of the pulling member 40 . The housing 120.

In the first sub-implementation, the housing 120 defines the position of the shielding member 30 through the sliding groove S2 to prevent the second movable end of the shielding member 30 from escaping from the housing 120 . In the second sub-implementation, the pulling force of the traction member 40 is used to define the shielding member 30 . Specifically, the two opposite ends of the traction member 40 are respectively connected to the shielding member 30 and the first force-applying member 50. The first force-applying member 50 provides a tensile force in the first preset direction to the shielding member 30 through the traction member 40. The first preset direction is the direction in which the first side Y1 points to the second side Y2. Therefore, the tightening force can cause the second movable end of the shielding member 30 to contact the side of the housing 120 away from the second side Y2. .

The first force-applying member 50 may be, but is not limited to, a coil spring, a motor, etc., which tightens the traction member 40 by winding. The traction member 40 can be bent, and may be, but is not limited to, a flexible rope. When the power adapter 3 is in the open state, the traction member 40 bypasses the side of the adapter body 10 where the pins 110 are provided. Under the tightening force of the first force-applying member 50 , the traction member 40 is close to the housing 120 and can Slide along the surface of the housing 120 .

It can be understood that in the first sub-implementation, the length of the chute S2 requires certain requirements, which limits the shape of the housing 120 . However, in the second sub-implementation, the chute S2 does not need to be provided, so the shape of the housing 120 is not limited, and the feasible housing 120 styles are more abundant.

Further, please refer to FIG. 18 . In the above manner in which the shielding member 30 is a rigid member, the central axis of the flip cover 20 relative to the housing 120 is the first preset axis O1 . The central axis of rotation of the shielding member 30 relative to the cover plate 210 is the second preset axis O2. The distance from the second preset axis O2 to the first preset axis O1 is a first distance L1. The distance from one end of the shielding member 30 close to the cover plate 210 (the first movable end) to the end of the shielding member 30 away from the cover plate 210 (the second movable end) is the second distance L2. The second distance L2 is greater than the first distance L1.

Specifically, since the whole body composed of the housing 120, the cover 210, and the shield 30 is similar to a slider crank mechanism, and the slider crank mechanism has a dead point, it cannot move when the slider crank mechanism is at the dead center position. In other words, when the flip cover 20 rotates relative to the housing 120 , when the vertical line connecting the first movable end and the second movable end of the shielding member 30 coincides with the first preset axis O1 and the second preset axis O2 When connected vertically, the flip cover 20 cannot further rotate relative to the housing 120 . Therefore, in this embodiment, the second distance L2 is set to be greater than the first distance L1, thereby preventing the shielding member 30 from moving to the connection line between the first preset axis O1 and the second preset axis O2, thereby avoiding the above-mentioned Dead center problem.

In the second embodiment, the shielding member 30 has a flexible structure, that is, the shielding member 30 will deform during movement. The following is a detailed introduction with reference to the attached drawings.

Referring to FIGS. 19 to 22 , an opening S5 is provided on the first side of the housing 120 . The opening S5 communicates with the internal space of the housing 120 . The adapter body 10 further includes a second force applying member 60 . The second force-applying member 60 is disposed in the internal space of the housing 120 . The shielding member 30 is a flexible member. One end of the shielding member 30 is connected to the cover plate 210 . The other end of the shielding member 30 is connected to the second force applying member 60 . When the power adapter 3 is in an open state, the second force-applying member 60 is used to tighten the shielding member 30 .

The second force-applying member 60 may be, but is not limited to, a coil spring, a motor, etc., which tightens the shielding member 30 by winding. The second force-applying member 60 is provided at an end of the housing 120 away from the flip cover 20 , and can provide a tightening force in a second direction to the shielding member 30 . The second preset direction is when the flip cover 20 points toward the second force-applying member 60 . direction. When the power adapter 3 is in the open state, the shielding member 30 will abut against the opening S5 and bend due to the tightening force. It can be understood that the arrangement of the second force-applying member 60 can facilitate pulling the shielding member 30 back into the housing 120 , and when the power adapter 3 is in a closed state, most of the shielding members 30 will hide the housing 120 inside to avoid being damaged by foreign objects. In this embodiment, the shielding member 30 may be, but is not limited to, cloth.

Please refer to Figure 23. Optionally, in the above embodiment, the cover 210 has a first fitting part 211, the shield 30 has a second fitting part 310, and the power adapter 3 also includes a rotating shaft 90. The rotating shaft 90 is inserted into the first fitting part 211 and the second fitting part 310 to realize the rotational connection between the cover plate 210 and the shielding member 30 . The material of the rotating shaft 90 can be, but is not limited to, plastic. Of course, there are other rotational connection forms between the cover plate 210 and the shielding member 30, which will not be described again here.

The above are several implementations of the shielding member 30. Other possible implementations will not be described in detail here. Next, we will introduce the flip cover 20, the housing 120, and the connection structure between the flip cover 20 and the housing 120.

Please refer to FIG. 24 , the main cover 220 includes a main body part 221 and a frame part 222 connected around the periphery of the main body part 221 . The frame portion 222 is generally U-shaped, and the frame portion 222 is rotatably connected to the housing 120 . The frame portion 222 has the third surface X3. The main body part 221 has the receiving space R2.

Please refer to FIG. 25 , the main body part 221 has a fourth surface X4 away from the third surface X3. The housing 120 has a third side Y3, and the pins 110 pass through the third side Y3. When the power adapter 3 is in a closed state, the fourth surface X4 and the third side Y3 are adjacent and opposite each other, that is, there is a gap between the fourth surface X4 and the third side Y3, so that This prevents the flip cover 20 from colliding with the housing 120 during rotation, thereby causing motion interference.

Please refer to FIG. 26 . When the power adapter 3 is in the open state, the fourth surface X4 is in contact with the second side Y2 of the housing 120 . That is to say, the fourth surface X4 is in contact with the second side Y2 . This arrangement prevents the flip cover 20 from over-rotating, and at the same time, prevents the user's fingers from passing between the fourth surface X4 and the second side Y2 and then touching the pin 110 .

Referring to FIG. 27 , the third side Y3 includes a first side Y31 , a second side Y32 and a third side Y33 that are bent and connected in sequence, thereby forming a step structure. The first surface Y31 is closer to the top of the pin 110 than the third surface Y33, where the top of the pin 110 refers to the part of the pin 110 that is away from the third side Y3 and exposed from the housing 120 outer end. The third surface Y33 is closer to the second side Y2 than the first surface Y31.

When the power adapter 3 is in a closed state, the fourth surface X4 and the third surface Y33 are spaced apart and face each other, and the vertical distance from the fourth surface X4 to the third surface Y33 is less than or equal to The vertical distance from the first surface Y31 to the third surface Y33. In other words, the fourth surface X4 is flush with the first surface Y31 , or the fourth surface X4 is further away from the top of the pin 110 than the first surface Y31 . With this arrangement, when the power adapter 3 is in a closed state, the flip cover 20 completely blocks the pin 110, so that the user will not see the reflection of the pin 110, and the power adapter 3 can also be made more beautiful. To illustrate from a reverse angle, if the fourth surface X4 is closer to the top of the pin 110 than the first surface Y31, there will be a gap between the fourth surface X4 and the first surface Y31 in the vertical direction. The side of 120 with the second side Y2 can see the pin 110 through the gap. The pin 110 is usually made of metal and seriously reflects under strong light, which is not conducive to the user. However, according to the arrangement of this implementation, it can Avoid reflection problems.

Referring to FIGS. 28 and 29 , the housing 120 has a fourth side Y4 and a fifth side Y5 arranged oppositely. The fourth side Y4 and the fifth side Y5 are located between the first side Y1 and the second side Y2. The power adapter 3 also includes a first shaft segment assembly 70 and a second shaft segment assembly 80 . The first shaft segment assembly 70 is connected to the side of the housing 120 having the fourth side Y4. The second shaft segment assembly 80 is connected to the side of the housing 120 having the fifth side Y5. The frame portion 222 of the flip cover 20 is rotatably connected to the housing 120 through the first shaft segment assembly 70 and the second shaft segment assembly 80 .

It can be understood that the first shaft segment assembly 70 and the second shaft segment assembly 80 are respectively connected to opposite ends of the housing 120, thereby preventing the first shaft segment assembly 70 and the second shaft segment assembly 80 from occupying the housing 120. internal space.

It should be noted that, in one embodiment, the first shaft segment assembly 70 and the second shaft segment assembly 80 may be fixedly connected to the housing 120 and rotationally connected to the frame portion 222 . In another embodiment, the first shaft segment assembly 70 and the second shaft segment assembly 80 may also be fixedly connected to the frame portion 222 and rotationally connected to the housing 120 .

A possible implementation of the first shaft segment assembly 70 and the second shaft segment assembly 80 will be introduced below with reference to the drawings.

Referring to FIG. 30 , the first shaft segment assembly 70 and the second shaft segment assembly 80 are composed of a first connecting piece 710 , a sleeve 720 , a second connecting piece 730 , and a cover piece 740 . Among them, the first connecting member 710 is fixedly connected to the housing 120, and its connection form may be, but is not limited to, hot melt or adhesive form. The second connecting member 730 is inserted into the sleeve 720 and connected to the first connecting member 710 to fix the sleeve 720 on the housing 120 .

The first connecting member 710 may be, but is not limited to, a nut or nut with threads. The second connecting member 730 may be, but is not limited to, a threaded bolt. The first connecting member 710 and the second connecting member 730 may be, but are not limited to, connected through threaded fitting.

The sleeve 720 at least partially protrudes from the housing 120 , and the frame portion 222 is sleeved on the outer periphery of the portion of the sleeve 720 that protrudes from the housing 120 , thereby achieving a rotational connection between the two.

The cover piece 740 covers the end of the sleeve 720 away from the housing 120 to cover the second connecting member 730 that penetrates the sleeve 720, so that it looks more beautiful.
