Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without any inventive effort, are intended to be within the scope of the application.

Reference herein to "an embodiment" or "implementation" means that a particular feature, structure, or characteristic described in connection with the embodiment or implementation may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, the present application provides an electronic device assembly 1, where the electronic device assembly 1 includes an electronic device 2 and a Power adapter 3 (Power adapter) as described in any of the following embodiments, and the Power adapter 3 is used to charge the electronic device 2.

The electronic device 2 may be, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a sound box, a smart watch, a bracelet, etc. The power adapter 3 is a conversion device that supplies the electronic device 2 with power supply. Typically, the power adapter 3 may convert an ac voltage to a dc voltage. For example, the power adapter 3 is plugged into the socket 4, receives the ac voltage output from the socket 4, and converts the received ac voltage into a dc voltage, which is used to charge the battery of the electronic device 2 for power consumption such as a mobile phone or a computer.

The power adapter 3 provided in the above-described embodiment is described in detail below with reference to the drawings.

Referring to fig. 2 to 4, the present application provides a power adapter 3, wherein the power adapter 3 includes an adapter body 10 and a flip cover 20.

The adapter body 10 includes pins 110 and a housing 120, the pins 110 being carried by the housing 120. The flip cover 20 is movably connected to the housing 120 so that the power adapter 3 has a closed state and an open state. The flip cover 20 has a first surface X1. The flip cover 20 has a through hole R1 located at the first surface X1. When the power adapter 3 is in the closed state, the flip cover 20 is closed to the adapter body 10, and the pins 110 are accommodated in the housing 120 and/or the flip cover 20. When the power adapter 3 is in the open state, the flip cover 20 is turned over to expose the adapter body 10, the pins 110 are exposed out of the through holes R1 of the first surface X1, and the first surface X1 forms a plugging surface of the power adapter 3.

The above components are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, the adapter body 10 includes a pin 110 and a housing 120, wherein the pin 110 is directly or indirectly supported by the housing 120.

The material of the pins 110 may be metal, such as copper alloy, aluminum alloy, etc. The pins 110 may be, but are not limited to, elongated. The end of the pin 110 for inserting into the socket 4 is arc-shaped so as to facilitate the insertion of the pin 110 into the socket 4. The number of pins 110 may be, but is not limited to, two, three, etc., and the present application is exemplified with only two oppositely disposed pins 110.

Referring to fig. 5, the adapter body 10 is a part for realizing the voltage conversion function of the power adapter 3. The adapter body 10 may also generally include a circuit board 130, an output port 140, the circuit board 130 and the output port 140 being at least partially housed within the housing 120. Wherein, the circuit board 130 is electrically connected to the pins 110, and the circuit board 130 is used for realizing voltage conversion. The output port 140 is electrically connected to the circuit board 130, and the output port 140 is used for being electrically connected to the electronic device 2 through the cable 5, so as to realize power supply to the electronic device 2. The output port 140 may be a USB interface or a Type-C interface, etc. It should be noted that the output port 140 may 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, and in other embodiments, the output port 140 may be disposed at other positions of the adapter body 10, such as a side surface.

The flip cover 20 is movably connected to the housing 120 so that the power adapter 3 has an open state (fig. 2) and a closed state (fig. 3 and 4). That is, the flip cover 20 is movable relative to the housing 120, so that the power adapter 3 can take two different forms, i.e., a closed state and an open state. It should be noted that the movable connection between 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 (fig. 2) and a second surface X2 (fig. 4) disposed opposite to each other, and a third surface X3 (fig. 3) disposed between the first surface X1 and the second surface X2. The flip cover 20 has a through hole R1 (see fig. 2 and 3) located on the first surface X1.

Referring to fig. 3, when the power adapter 3 is in the closed state, the third surface X3 faces away from the housing 120, the flip cover 20 is closed on the adapter body 10, and the pins 110 are accommodated in the housing 120 and/or the flip cover 20. That is, the closed state is a state in which the pins 110 are received in the housing 120 and/or the lid 20. Specifically, in the first embodiment, the pins 110 are retractable with respect to the housing 120, and the pins 110 are retracted into the housing 120 so as to be entirely accommodated in the housing 120 during the switching of the power adapter 3 from the open state to the closed state. Pins 110 extend out of housing 120 during the transition of power adapter 3 from the off state to the on state. 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 are always exposed outside the housing 120, and when the power adapter 3 is in the closed state, the pins 110 exposed outside the housing 120 are accommodated in the flip cover 20. It should be noted that, the following description of the present application is mainly given by way of example of the second embodiment (at least part of pins 110 are always exposed outside of housing 120), and the related structural arrangements of flip cover 20, housing 120, etc. are equally applicable to the first embodiment.

Referring to fig. 2, when the power adapter 3 is in the open state, the flip cover 20 is turned over to expose the adapter body 10, the first surface X1 faces away from the housing 120, the pins 110 are exposed out of the through holes R1 of the first surface X1, and the first surface X1 forms a plugging surface of the power adapter 3. That is, the open state is an exposed state in which the pins 110 are exposed to the outside, 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 is changed from the third surface X3 to the first surface X1, and the pins 110 protrude from the through holes R1 on the first surface X1, and the first surface X1 thus serves as a plugging surface.

Wherein the plugging surface refers to an outer surface of the power adapter 3 facing the socket 4, or being adjacent to the socket 4, or being attached to the socket 4 when the pins 110 of the power adapter 3 are plugged into the socket 4. For the power adapter 3, when the power adapter 3 is plugged into the socket 4, in order to avoid the power of the socket 4 leaking out through the pins 110, the user is injured. Therefore, the above-described plugging surface satisfies the safety regulation requirement (safety regulation requirement) of the power adapter 3, that is, the distance from the edge of the pin 110 to the edge of the plugging surface is greater than or equal to the safety regulation distance (or referred to as safety distance). The safety distance may be, but not limited to, 5.1mm, 6.3mm, 6.5mm, 7.9mm, etc., and may be different for different regions or different countries, which is not limited in the present application.

Compared with the prior art, the flip cover 20 in the power adapter 3 is movably connected with the housing 120, so that the power adapter 3 has a closed state and an open state, and when the power adapter 3 is required to supply power to the electronic equipment 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 the exposed pins 110 are plugged into the socket 4 to realize charging. When the power adapter 3 is not needed, the power adapter 3 can be switched to a closed state, so that the pins 110 are contained in the shell 120 or the flip 20, damage to the pins 110 can be avoided, such as impact deformation, and risks of functional failure caused by bending are avoided, and the service life of the power adapter 3 can be prolonged.

Referring to fig. 2 to 4, the housing 120 has a first side Y1 (fig. 2 and 3) and a second side Y2 (fig. 4) disposed opposite to each other. When the power adapter 3 is in the off 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 of the power adapter 3. When the power adapter 3 is in an open state, opposite ends of the first surface X1 protrude from the first side face Y1 and the second side face Y2, respectively.

In the present embodiment, when the power adapter 3 is in the open state, since the first surface X1 as the plugging surface protrudes from both the first side Y1 and the second side Y2 and the first surface X1 is located on the flip cover 20, the adapter body 10 will not be limited to the safety requirements when the adapter body 10 is dimensioned, 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 to be 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 is used as a plugging surface, so that only the self size of the first surface X1 is limited by the safety requirements, and the maximum distance between the first surface X1 and the second surface X2 (the thickness of the flip cover 20) can be designed to be as small as possible. In summary, the thickness of the adapter body 10 and the flip cover 20 are not limited by the safety requirements, in other words, the overall thickness of the power adapter 3 can be set as small as possible, thereby meeting the light and thin requirements of users.

In the related art, a single flip scheme and a double flip scheme are generally employed to reduce the thickness of the power adapter.

For a single flip scheme: the power adapter comprises an adapter body and a flip cover, wherein the flip cover is rotationally connected with the adapter body. The adapter body is provided with a first end face, and the pins penetrate through the first end face to be exposed to the outside. The flip cover has a second end face. The thickness of the power adapter is the largest of the width H1 of the first end face and the width H2 of the second end face. The first end face and the second end face each other when the power adapter is in the off state. When the power adapter is switched from a closed state to an open state, the flip rotates to one side (rotated 180 degrees) of the adapter body, after the flip rotates, the first end face and the second end face are positioned on the same plane, and the first end face and the second end face jointly form a plug-in face. It will be appreciated that, since the plug face is formed by the first end face and the second end face together, and the plug face needs to meet the safety requirements, the widths of the first end face and the second end face cannot be set to be small at the same time, so that the thickness of the power adapter cannot be designed to be as small as possible.

For the double flip scheme: the power adapter comprises an adapter body and two flip covers, wherein the two flip covers are oppositely arranged and are both rotationally connected with the adapter body. The adapter body is provided with a first end face, and the pins penetrate through the first end face to be exposed to the outside. One of the two flip covers has a second end face and the other one has a third end face, and the thickness of the power adapter is the largest of the width H1 of the first end face and the sum H2 of the widths of the second end face and the third end face. When the power adapter is in a closed state, the second end face and the third end face the first end face. When the power adapter is switched from a closed state to an open state, the two flip covers respectively rotate to two opposite sides of the adapter body (the two flip covers respectively rotate 180 degrees in opposite directions), after the flip covers rotate, the first end face, the second end face and the third end face are positioned on the same plane, and the first end face, the second end face and the third end face form a plug-in face together. In the double-flip scheme, the plugging surface is formed by the first end surface, the second end surface and the third end surface, and the plugging surface is required to meet the safety requirements, so that the widths of the first end surface, the second end surface and the third end surface cannot be set to be very small at the same time, and the thickness of the power adapter cannot be designed to be as small as possible. In addition, in the double-flip scheme, each flip is rotatably connected to the adapter body, so that two rotary connecting mechanisms exist, and if the strength of the rotary connecting mechanism is ensured, the size of the structure is required to be increased, so that the thickness of the power adapter is increased; conversely, if the thickness of the power adapter is to be ensured to be small, the strength of the rotary connection structure is weakened, and therefore, there is a design contradiction point between the strength and the thickness in the double-flip scheme.

Compared with the single flip scheme and the double flip scheme, the thickness of the power adapter 3 provided by the application is the distance between the first side surface Y1 and the second side surface Y2 or the distance between the first surface X1 and the second surface X2, however, the two distances are not influenced by the safety requirements, and only the self size of the first surface X1 is limited by the safety requirements, so that the power adapter 3 provided by the application can be provided with smaller thickness compared with the single flip scheme and the double flip scheme. In addition, only one flip cover 20 needs to be designed in the application, so that the contradiction between strength and thickness in the scheme of the double flip cover 20 can be avoided.

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

Referring to fig. 6, it should be noted that a 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 pin 110 to the right edge of first surface X1 is greater than or equal to the safety distance.

Referring to fig. 2, 3 and 7, the flip cover 20 includes a cover plate 210 and a main cover 220 connected to each other. Wherein the cover 210 is made of an insulating material, such as plastic, rubber, ceramic, 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 facing away from the second surface X2. The main cover 220 is rotatably connected to the housing 120, and the main cover 220 has a receiving space R2 communicating with the through hole R1. When the power adapter 3 is in the off state, the pins 110 are located in the accommodating space R2. It should be noted that, in the present embodiment, the pins 110 are fixed relative to the housing 120, and at least a portion of the pins 110 are located outside the housing 120.

Specifically, when the power adapter 3 is in the open state, the pins 110 are exposed to the outside through the through holes R1 in the cover plate 210, and in this state, can be inserted into the socket 4. When the power adapter 3 is not in use, the flip cover 20 can be rotated reversely (the second surface X2 is rotated in a direction away from the second side surface Y2), the pins 110 gradually enter the accommodating space R2 of the main cover 220 through the through holes R1, and the power adapter 3 is switched from the open state to the closed state. When the power adapter 3 is switched to the off state, the pins 110 are located in the accommodating space R2, so that the pins 110 can be protected from being damaged by foreign objects. Similarly, to switch the power adapter 3 in the off state to the on state, only the flip cover 20 is required to be rotated forward (the second surface X2 is rotated toward the direction approaching the second side Y2), and the pins 110 gradually enter from the accommodating space R2 and pass through the through holes R1, and finally are exposed to the outside.

The cover plate 210 and the main cover 220 may be in an integral structure or a split structure. The integrated structure means that the cover plate 210 and the main cover 220 are integrally formed. The split structure is that the cover plate 210 and the main cover 220 are separately processed and then connected together to form the flip cover 20. The present application is illustrated by way of example only in a split configuration. In the split structure, the connection form of the cover plate 210 and the main cover 220 may be, but not limited to, bonding (glue bonding, double-sided adhesive bonding), connection using a connector (screw, etc.), fastening, etc.

Referring to fig. 6, the power adapter 3 further includes a shielding member 30, and the shielding member 30 is made of an insulating material, such as plastic, rubber, ceramic, glass, etc. 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 along with 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 having the first side Y1, and the shielding member 30 shields the junction J between the cover 210 and the housing 120.

It will be appreciated that during insertion of the power adapter 3 into the receptacle 4 in the open state, the user's fingers need to be simultaneously held against the first and second sides Y1, Y2 of the housing 120 to provide a force to insert the power adapter 3 into the receptacle 4. However, there is resistance in the insertion process, so that 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 in a state protruding from the first side Y1. If the shielding member 30 is not provided, the finger attached to the first side Y1 may reach the junction J of the cover 210 and the housing 120 and abut against the cover 210, and the abutting action makes the cover 210 and the housing 120 generate a larger gap, and the finger further extends into the gap and touches the pin 110, so as to finally generate an electric shock accident.

Therefore, the shielding member 30 in the present embodiment is configured to shield or shelter the junction J, and even if the finger attached to the first side Y1 slides toward the cover 210, the finger is blocked by the shielding member 30, so that the finger can be prevented from touching the pins 110 when reaching the junction J. Further, since the cover 20 can rotate relative to the housing 120, the shielding member 30 is movably connected to the cover 210 and the adapter body 10 in this embodiment, so that the shielding member 30 can generate corresponding movement and can not block movement of the cover 20 during rotation of the cover 20 relative to the housing 120.

Several possible embodiments of the shield 30 are described in detail below in conjunction with the accompanying drawings.

In the first embodiment, the shield 30 is a rigid member, i.e., the shield 30 does not deform or deform significantly during movement.

Fig. 8 to 11 and 12 show schematic views of the flip cover in the case of rotating 0 °, 30 °, 60 ° and 90 ° relative to the housing in fig. 12. One end of the shielding member 30 is rotatably connected to one end of the cover plate 210 away from the third surface X3. One end of the shielding member 30 away from the cover plate 210 is slidably connected to the first side Y1 of the housing 120, and can slide in a direction approaching or moving away from the pins 110.

Specifically, for ease of illustration, the shield 30 is defined herein as having first and second movable ends that face away from 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. Referring to fig. 8, 9 and 12, when the power adapter 3 is in the off state, the shielding member 30 is parallel or almost parallel to the first side Y1 of the housing 120, and the second movable end is far away from the pins 110. Referring to fig. 10 to 11 and 12, when the power adapter 3 is in the open state, the shielding member 30 is inclined with respect to the first side Y1 of the housing 120 to face the interface J, and the second movable end is close to the pin 110. During the switching of the power adapter 3 from the closed state to the open state, the first movable end moves away from the housing 120 gradually following the movement of the cover plate 210, and the second movable end moves in a direction approaching the pins 110, so that the shutter 30 is gradually tilted. In the process of switching the power adapter 3 from the on state to the off state, the first movable end moves along with the cover plate 210 to gradually approach the housing 120, and the second movable end moves in a direction away from the pins 110, so that the inclination angle of the shielding member 30 gradually decreases.

Referring to fig. 13, the housing 120 has a receiving groove S1 recessed from the first side surface Y1 toward the second side surface Y2. When the power adapter 3 is in the off state, the shielding member 30 is accommodated in the accommodation groove S1. It can be appreciated that the accommodating groove S1 can perform a limiting function on the shielding member 30, so that on one hand, the shielding member 30 can be protected to a certain extent, and the shielding member 30 is prevented from being skewed under the action of external force to damage the connection structure of the shielding member 30 and the cover plate 210; on the other hand, the power adapter 3 can be more attractive.

Further, the first side Y1 includes a first sub-surface Y11 and a second sub-surface Y12, where the first sub-surface Y11 is farther from the second side Y2 than the second sub-surface Y12, and the second sub-surface Y12 is used as a bottom wall of the accommodating groove S1. Alternatively, the surface of the shutter 30 facing away from the second side Y2 is flush with the first sub-surface Y11 when the power adapter 3 is in the off state.

When the shield 30 is a rigid member, in a first seed embodiment: referring to fig. 14, the housing 120 further has a chute S2 recessed from a sidewall of the accommodating groove S1. The end of the shielding member 30 away from the cover 210 is at least partially located in the sliding slot S2, and can slide in the sliding slot S2 toward or away from the pins 110.

Specifically, two opposite side walls of the accommodating groove S1 are respectively provided with a sliding groove S2, the two sliding grooves S2 are oppositely arranged, and the extending direction of the sliding grooves S2 points to the pins 110. The sliding slot S2 is configured to receive at least a portion of the shutter 30, so as to guide a sliding direction of the shutter 30, and also to limit a position of the shutter 30 to prevent the shutter 30 from falling off from the housing 120.

Alternatively, referring to fig. 15, an end (a second movable end) of the shielding member 30 away from the cover plate 210 is provided with two protruding portions 320, the two protruding portions 320 are respectively protruding from opposite sides of the shielding member 30, and each protruding portion 320 is disposed in a corresponding sliding slot S2 and is slidable in the sliding slot S2. Further alternatively, the outer surface of the boss 320 is cylindrical.

Alternatively, referring to fig. 16, a sliding rod 330 is disposed at an end (a second movable end) of the shielding member 30 away from the cover plate 210, the sliding rod 330 penetrates through the shielding member 30 and protrudes from opposite sides of the shielding member 30, and portions of the two ends of the sliding rod 330 protruding from the shielding member 30 are disposed in the corresponding sliding slots S2 and can slide in the sliding slots S2. Further alternatively, the outer surface of the slide bar 330 is cylindrical.

It should be noted that, in the first seed embodiment, the length of the sliding slot S2 in the extending direction is greater than or equal to the movement travel of the second movable end of the covering member 30, so as to ensure that the protruding portion 320 or the sliding rod 330 located at the second movable end does not fall out of the sliding slot S2 during the sliding process. In other words, the boss 320 or the slide bar 330 at the second movable end is always located within the slide slot S2, regardless of whether the power adapter 3 is in the open state or the closed state.

When the shielding member 30 is a rigid member, in the second seed embodiment, referring to fig. 17, the power adapter 3 further includes a traction member 40 and a first force application member 50. Wherein the first force application member 50 is disposed in the flip cover 20. One end of the traction member 40 is connected to the first force application member 50, and the other end of the traction member 40 is connected to an end (second movable end) of the shielding member 30 remote from the cover plate 210. When the power adapter 3 is in the open state, the first urging member 50 tightens the traction member 40 so that the shielding member 30 abuts against the housing 120 under the tightening of the traction member 40.

In the first seed embodiment, the housing 120 defines the position of the shutter 30 by the chute S2 to avoid the second movable end of the shutter 30 from coming out of the housing 120. In the second seed embodiment, the pulling force of the pulling member 40 is used to define the shield 30. Specifically, opposite ends of the traction member 40 are respectively connected to the shielding member 30 and the first force application member 50, and the first force application member 50 provides a tensioning force in a first preset direction to the shielding member 30 through the traction member 40, where the first preset direction is that the first side Y1 points to the second side Y2, so that the tensioning force can make the second movable end of the shielding member 30 abut against a side of the housing 120 facing away from the second side Y2.

Wherein the first force application member 50 may be, but is not limited to, a coil spring, a motor, etc., which tightens the traction member 40 by winding. Traction member 40 is capable of bending 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 provided with the pins 110, and the traction member 40 is tightly attached to the housing 120 under the action of the tensioning force of the first force application member 50 and can slide along the surface of the housing 120.

It will be appreciated that in the first seed embodiment, the length of the chute S2 is required to be certain, so that the shape of the housing 120 is limited. However, in the second seed embodiment, the chute S2 is not required, so that the outer shape of the housing 120 is not limited, and the possible housing 120 is more abundant.

Further, referring to fig. 18, in the manner that the shielding member 30 is a rigid member, a central axis of rotation of the flip cover 20 relative to the housing 120 is a first preset axis O1. The central axis of rotation of the shielding member 30 relative to the cover plate 210 is a 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 the end (first movable end) of the shield 30 near the cover plate 210 to the end (second movable end) of the shield 30 far from the cover plate 210 is a second distance L2. The second distance L2 is greater than the first distance L1.

Specifically, since the housing 120, the cover plate 210, and the shielding member 30 are formed as a whole to approximate the slider-crank mechanism, the slider-crank mechanism has a dead point, and the slider-crank mechanism cannot move when it is at the dead point. In other words, during the rotation of the flip cover 20 relative to the housing 120, when the vertical line of the first movable end and the second movable end of the shutter 30 coincides with the vertical line of the first preset axis O1 and the second preset axis O2, the flip cover 20 cannot further rotate relative to the housing 120. Therefore, in the present embodiment, the second distance L2 is set to be greater than the first distance L1, so that the shutter 30 can be prevented from moving onto the line connecting the first preset axis O1 and the second preset axis O2, thereby avoiding the dead point problem described above.

In a second embodiment, the shield 30 is of a flexible construction, i.e. the shield 30 will deform during movement. The following is a detailed description with reference to the accompanying drawings.

Referring to fig. 19 to 22, an opening S5 is formed on the first side of the housing 120. The opening S5 communicates with the inner space of the housing 120. The adapter body 10 further includes a second force application member 60. The second force application member 60 is disposed in the inner space of the housing 120. The shield 30 is a flexible member. One end of the shutter 30 is connected to the cover plate 210. The other end of the shutter 30 is connected to the second force application member 60. The second force application member 60 is used to tighten the shutter 30 when the power adapter 3 is in the open state.

Wherein the second force application member 60 may be, but is not limited to, a coil spring, a motor, etc., which tightens the shutter 30 by winding. The second force application member 60 is disposed at an end of the housing 120 away from the flip cover 20, and is capable of providing a tensioning force in a second direction to the shielding member 30, where the second predetermined direction is a direction in which the flip cover 20 points toward the second force application member 60. When the power adapter 3 is in the open state, the shutter 30 will bend against the opening S5 due to the tension. It will be appreciated that the provision of the second force application member 60 may facilitate the retraction of the shutter 30 into the housing 120 and that when the power adapter 3 is in the off state, a substantial portion of the shutter 30 will be concealed within the housing 120 and thus protected from damage by foreign objects. In the present embodiment, the shield 30 may be, but is not limited to, cloth.

Referring to fig. 23, in the above embodiment, alternatively, the cover 210 has a first mating portion 211, the shielding member 30 has a second mating portion 310, and the power adapter 3 further includes a rotating shaft 90, and the rotating shaft 90 is disposed through the first mating portion 211 and the second mating portion 310, so as to implement a rotational connection between the cover 210 and the shielding member 30. The material of the rotating shaft 90 may be, but not limited to, plastic. Of course, other rotational connections exist for the cover plate 210 and the shutter 30, and are not described in detail herein.

The above are several embodiments of the shield 30, and for other possible embodiments, details are not provided herein. The following begins with the description of the flip 20, the housing 120, and the connection structure of the flip 20 and the housing 120.

Referring to fig. 24, the main cover 220 includes a main body 221 and a frame 222 surrounding the periphery of the main body 221. The frame portion 222 is substantially 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 221 has the accommodation space R2.

Referring to fig. 25, the main body 221 has a fourth surface X4 far 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 the off state, the fourth surface X4 is adjacent to and spaced from the third side Y3, that is, a gap exists between the fourth surface X4 and the third side Y3, so that the problem of motion interference caused by the collision of the flip cover 20 against the housing 120 during rotation can be avoided.

Referring to fig. 26, when the power adapter 3 is in the open state, the fourth surface X4 abuts against the second side Y2 of the housing 120, that is, the fourth surface X4 abuts against the second side Y2, so that the flip cover 20 is prevented from rotating excessively, and meanwhile, a finger of a user is prevented from passing between the fourth surface X4 and the second side Y2 and touching the pin 110.

Referring to fig. 27, the third side surface Y3 includes a first surface Y31, a second surface Y32, and a third surface Y33, which are sequentially bent and connected, thereby forming a step structure. The first face Y31 is closer to the top end of the pin 110 than the third face Y33, wherein the top end of the pin 110 is the end of the pin 110 far from the third face Y3 and exposed outside the housing 120. The third face Y33 is more adjacent to the second side face Y2 than the first face Y31.

When the power adapter 3 is in the off state, the fourth surface X4 is spaced apart from the third surface Y33, and a vertical distance from the fourth surface X4 to the third surface Y33 is smaller than or equal to a vertical distance from the first surface Y31 to the third surface Y33. In other words, fourth surface X4 is flush with first face Y31, or fourth surface X4 is farther from the tip of pin 110 than first face Y31. By this arrangement, when the power adapter 3 is in the closed state, the cover 20 completely shields the pins 110, so that the user cannot see the reflection of light of the pins 110, and the power adapter 3 is more beautiful. In the opposite direction, if the fourth surface X4 is closer to the top end of the pin 110 than the first surface Y31, there is a gap between the fourth surface X4 and the first surface Y31 in the vertical direction, and the user can see the pin 110 through the gap from the side of the housing 120 having the second side Y2, and the pin 110 is usually made of metal, so that the reflection of light is serious under intense light, which is unfavorable for the user, and the reflection problem can be avoided according to the arrangement of the present embodiment.

Referring to fig. 28 and 29, the housing 120 has a fourth side Y4 and a fifth side Y5 disposed opposite to each other. 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 further comprises a first shaft section assembly 70 and a second shaft section assembly 80. The first shaft segment assembly 70 is connected to a side of the housing 120 having a fourth side Y4. The second shaft segment assembly 80 is connected to a side of the housing 120 having a fifth side Y5. The frame 222 of the flip cover 20 is rotatably coupled to the housing 120 by the first shaft segment assembly 70 and the second shaft segment assembly 80.

It will be appreciated that the first shaft segment assembly 70 and the second shaft segment assembly 80 are connected to opposite ends of the housing 120, respectively, such that the first shaft segment assembly 70 and the second shaft segment assembly 80 can be prevented from occupying the inner space of the housing 120.

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

One possible embodiment of the first shaft segment assembly 70 and the second shaft segment assembly 80 is described below in connection with the accompanying drawings.

Referring to fig. 30, the first shaft section assembly 70 and the second shaft section assembly 80 are each composed of a first connector 710, a sleeve 720, a second connector 730, and a cover plate 740. The first connecting member 710 is fixedly connected to the housing 120, and the connection mode thereof may be, but not limited to, a hot-melt mode or an adhesive mode. The second connector 730 is inserted into the sleeve 720 and connected to the first connector 710, thereby fixing the sleeve 720 to the housing 120.

The first connector 710 may be, but is not limited to, a threaded nut, a nut. The second connector 730 may be, but is not limited to, a threaded bolt. The first connector 710 and the second connector 730 may be, but are not limited to, connected by a threaded fit.

The sleeve 720 protrudes from the housing 120 at least partially, and the frame portion 222 is sleeved on the outer periphery of the portion of the sleeve 720 protruding from the housing 120, so that the sleeve 720 and the housing 120 are rotatably connected.

The cover 740 covers the end of the sleeve 720 away from the housing 120 to cover the second connecting member 730 penetrating the sleeve 720, which is more beautiful.

While embodiments of the present application have been shown and described above, it should be understood that the above embodiments are illustrative and not to be construed as limiting the application, and that variations, modifications, alternatives and alternatives to the above embodiments may be made by those skilled in the art within the scope of the application, which is also to be regarded as being within the scope of the application.
