Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

As shown in fig. 1 and 4, in one embodiment, a power adapter 10 is provided that includes a body, a protective cover 20, and a flexible member 70. The body comprises a housing 30 and a pin 60, the pin 60 is connected to the housing 30, and the housing 30 has a receiving space 103 (shown in fig. 6 a). It is understood that "connected" includes direct connection in which the pins 60 are directly connected to the housing 30 and indirect connection in which the pins 60 are connected to the elements in the receiving space 103 of the housing 30 so as to be fixed to the housing 30 or movable together with the elements in the receiving space 103 relative to the housing 30 to protrude from the housing 30 or be received in the receiving space 103.

In one embodiment, the housing 30 has a first end surface 33, and the pins 60 protrude from the first end surface 33. The protective cover 20 has a first bottom surface 140 connected to the housing 30, and the first bottom surface 140 and the first end surface 33 can form a working mating surface 90. It will be appreciated that when the power adapter 10 is electrically connected to an external power source, the working mating surface 90 is the surface of the power adapter 10 that is attached to or adjacent to the external power source. In one embodiment, the distance between the pins 60 and the edge of the working mating surface 90 is not less than a predetermined value, such as 5.1mm or 6.5mm or 7.9mm, so that the power adapter 10 can meet the safety requirements. The flexible member 70 is coupled between the housing 30 and the protective cover 20 and fills a gap between the housing 30 and the protective cover 20.

The power adapter 10 of the embodiment of the present application forms the working mating surface 90 with the first bottom surface 140 and the first end surface 33, so that the pins 60 can meet the use condition. Since the pins 60 do not occupy the space inside the housing 30, the size of the housing 30 can be reduced, and the overall size of the power adapter 10 can be reduced, resulting in good portability. In the power adapter 10 of the embodiment of the present application, due to the arrangement of the protective cover 20, the working mating surface 90 can be formed by matching the protective cover 20 and the housing 30 to meet the use requirement (e.g., the safety requirement) of the power adapter 10, so that the thickness of the housing 30 itself can be set to be smaller (e.g., much smaller than the preset value), and the overall volume of the power adapter 10 can be greatly reduced compared with the volume of the power adapter 10 in the related art. The flexible member 70 fills the gap between the housing 30 and the protective cover 20, providing the power adapter 10 with appearance integrity.

As shown in fig. 1-4, in another embodiment, the protective cover 20 can be rotated relative to the housing 30 such that the power adapter 10 has a first state and a second state. In the first state, the protective cover 20 is covered on the housing 30, and at least part of the pins 60 are accommodated in the protective cover 20; in the second state, the first bottom surface 140 of the protective cover 20 is flush with the first end surface 33 of the housing 30 or has a height difference within a predetermined range, and forms the working engagement surface 90. It is understood that all "flush" described in the embodiments of the present application may also be "substantially flush", and that flush may be entirely within a plane, and there may be a height difference within a certain range, such as a height difference between the first bottom surface 140 and the first end surface 33 of the protective cover 20 of no more than 2mm or 5mm or no more than 10mm or other dimensions, such as a height difference of no more than 1mm, which is also within the scope of the present application. The circuit board 80 (shown in fig. 6 a) is disposed in the receiving space 103 of the housing 30, and the circuit board 80 is electrically connected to the pins 60. In an embodiment, the housing 30 is a rectangular parallelepiped or square structure, and the edge of the housing 30 can be smoothly transited, so that the power adapter 10 has no rib and has a good hand feeling. In other embodiments, the body may also be a cylindrical structure or other structures, and is not limited herein.

As shown in FIGS. 1 and 4, in one embodiment, the block-out cover 20 includes a first block-out cover 100 and a second block-out cover 200. In the first state, the first protective cap 100 and the second protective cap 200 are attached and fixed.

The plug 60 is fixed to the first end surface 33 of the housing 30 and is located at the same end as the first protective cover 100 and the second protective cover 200. The shell 30 is provided with a charging interface 341, the charging interface 341 and the pin 60 are respectively located at two opposite ends of the shell 30, and the external electronic element can penetrate through the charging interface 341 and be electrically connected with the circuit board 80, so that the external electronic element is electrically connected with the pin 60, and after the power adapter 10 is electrically connected with the power supply, the power supply can supply power to the electronic element. It should be understood that the electronic component may be an intermediate connection line such as a data line, an electronic device such as a mobile phone, a watch, a tablet, or a computer, or a combination of an electronic device and a corresponding data line, which is not limited herein.

As shown in fig. 1-4, in one embodiment, the power adapter 10 includes a length direction, i.e., a Y-direction, a width direction, i.e., an X-direction, and a thickness direction, i.e., a Z-direction. The pins 60 extend in the Y direction, which is the longitudinal direction of the power adapter 10, i.e., the longitudinal direction of the pins 60 is the Y direction. The housing 30 includes a first surface 31 and a second surface 32 opposite to each other, a first side surface 35 and a second side surface 36 opposite to each other, and a first end surface 33 and a second end surface 34 opposite to each other. The first surface 31 and the second surface 32 define a thickness direction of the power adapter 10, i.e., a Z direction, the first side surface 35 and the second side surface 36 define a width direction of the power adapter 10, i.e., an X direction, the first end surface 33 and the second end surface 34 define a length direction of the housing 30, and the length direction of the power adapter 10, i.e., a Y direction, is the same as the length direction of the housing 30. The pins 60 extend out of the housing 30 along the length of the power adapter 10. In another embodiment, the pins 60 may also extend along the width of the power adapter 10, and may be designed according to the actual requirements of the power adapter 10.

The adjacent faces of the housing 30 are chamfered and smoothly transitioned so that the power adapter 10 has a smooth and rounded feel. The plug 60 is fixed and protruded from the first end surface 33, the first protection cover 100 is fixed at the boundary between the first end surface 33 and the first surface 31, and the second protection cover 200 is fixed at the boundary between the first end surface 33 and the second surface 32. It will be appreciated that a chamfer may or may not be provided between the first end surface 33 and the adjacent surface.

As shown in fig. 4 and 6a, in one embodiment, the housing 30 is made of plastic. The housing 30 includes a first case 301 and a second case 302, and the pins 60 are fixed to the first case 301. The first case 301 and the second case 302 are fixed by ultrasonic heat fusion or other processes. The pin 60 and the first shell 301 are molded integrally by an in-mold, and the first shell 301 is opened with a second receiving groove 331 for subsequent installation of the hinge assembly. It is understood that the first shell 301 and the second shell 302 are assembled together to form the first surface 31, the second surface 32, the first side surface 35, and the second side surface 36.

As shown in fig. 4 and 6a, in an embodiment, the first protective cover 100 is assembled from a first outer shell and a first inner shell, and includes a first outer surface 110 and a first inner surface 120 that are opposite to each other, a first top surface 130 and a first bottom surface 140 that are opposite to each other, and a first left side surface 150 and a first right side surface 160 that are opposite to each other. The first outer surface 110 is located on the first outer shell and the first inner surface 120 is located on the first inner shell. The adjacent surfaces of first protective cap 100 may have a smooth transition therebetween, such that first protective cap 100 has a smooth feel. It is understood that the first bottom surface 140 may or may not have a chamfer to provide a smooth transition with the adjacent surface. The second protective cover 200 is assembled from a second outer shell and a second inner shell, and includes a second outer surface 210 and a second inner surface 220 that are opposite to each other, a second top surface 230 and a second bottom surface 240 that are opposite to each other, and a second left side surface 250 and a second right side surface 260 that are opposite to each other. The second outer surface 210 is located on the second outer shell and the second inner surface 220 is located on the second inner shell. The adjacent surfaces of the second protective cover 200 can be smoothly transited, so that the second protective cover 200 has a smooth feel. It will be appreciated that the second bottom surface 240 may or may not have a chamfer with a smooth transition to the adjacent surface.

As shown in fig. 2, 7 and 8, in an embodiment, the first protective cover 100 and the second protective cover 200 can rotate relative to the housing 30 about the width direction of the power adapter 10, so that the first protective cover 100 and the second protective cover 200 have a first state and a second state, i.e., the power adapter 10 has the first state and the second state. In another embodiment, the first protective cover 100 and the second protective cover 200 can also rotate relative to the housing 30 about the length direction of the power adapter 10. As shown in fig. 8, in the second state, the first protective cover 100 and the second protective cover 200 are away from each other, the first protective cover 100 is attached to one side of the housing 30, the second protective cover 200 is attached to the other side of the housing 30, the end surfaces of the first protective cover 100, the second protective cover 200, which are connected to the housing 30, are flush with the end surface of the housing 30 where the pin 60 is disposed, that is, the first bottom surface 140 and the second bottom surface 240 are flush with the first end surface 33, the first bottom surface 140, the second bottom surface 240, and the first end surface 33 together form the working mating surface 90, and the pin 60 is exposed. The user may insert the prongs 60 into the power source with the working mating surface 90 attached to the power source.

In the embodiments of the present application, all "fits" described may be substantially fits, that is, fits described in the embodiments of the present application include at least the following cases: in the first case, two attached surfaces are completely attached without gaps; in the second case, a gap exists between two surfaces to be attached, for example, the gap between the first protective cover 100 and the second protective cover 200 and the surfaces on two sides of the housing 30 is not greater than 1mm or 2mm or other dimensions, and in this case, within the protection scope of the present application, the two surfaces to be attached may be parallel or non-parallel; in the third case, two surfaces to be attached are in partial contact, that is, the two surfaces to be attached are not completely attached but partially attached, and a gap exists between the two parts.

The first bottom surface 140, the second bottom surface 240 and the first end surface 33 together form the working engagement surface 90, and the first bottom surface 140 may be higher than the first end surface 33 or lower than the first end surface 33, that is, there is a height difference between the first bottom surface 140 and the first end surface 33, and the height difference is within a set range, which may be not greater than 2mm, for example, 1 mm. Similarly, the second bottom surface 240 may have a height difference from the first end surface 33 within a predetermined range.

As shown in fig. 1 and 2, in the first state, the entire structure of the pin 60 is covered by the first protective cover 100 and the second protective cover 200, the first inner surface 120 and the second inner surface 220 are attached to and contact each other, the first outer surface 110 is flush with the first surface 31, the second outer surface 210 is flush with the second surface 32, the first left side 150 is flush with the first side 35, and the first right side 160 is flush with the second side 36. The surfaces may be flush with each other, coplanar, or have some height difference, and are within the scope of the present application. When the first inner surface 120 and the second inner surface 220 are attached, three cases including the above explanation about the attachment are not described herein. In the first state, the pins 60 are hidden by the cover, and when the user puts the power adapter 10 into a pocket or a trunk, the power adapter 10 does not damage the surrounding objects. In another embodiment, in the first state, a part of the structure of the pin 60 is covered by the first protective cover 100 and the second protective cover 200, and a part of the structure is exposed from or protrudes from the first protective cover 100 and the second protective cover 200.

In one embodiment, as shown in FIGS. 1 and 4, the first and

second covers

100 and 200 are pivotally coupled to the edge of the first end 33 of the housing 30 by a hinge assembly having outer surfaces that are substantially flush with the first and

second surfaces

31 and 32, respectively, in the first position. It can be seen that the first protective cap 100 rotates around the central axis, and the central axis is located at the side of the first surface 31 facing the inside of the housing 30; the second protective cap 200 is rotated about another central axis located on the side of the second surface 32 facing the interior of the housing 30. If the first outer surface 110 intersects the first bottom surface 140 at a right angle and the first end surface 33 intersects the first surface 31 at a right angle, when the first protective cover 100 rotates around the central axis, the intersection of the first outer surface 110 and the first bottom surface 140 will interfere with the intersection of the first end surface 33 and the first surface 31. Therefore, in order to facilitate the rotation of the first protection cover 100, a rounded corner or an arc surface is required to be disposed at the intersection of the first outer surface 110 and the first bottom surface 140, and a rounded corner or an arc surface is disposed at the intersection of the first end surface 33 and the first surface 31, so as to provide an avoiding space for the rotation of the first protection cover 100. Similarly, in order to facilitate the rotation of the second protective cover 200, a rounded corner or an arc surface is required to be disposed at the intersection of the second outer surface 210 and the second bottom surface 240, and a rounded corner or an arc surface is disposed at the intersection of the first end surface 33 and the second surface 32, so as to provide an avoiding space for the rotation of the second protective cover 200. In the first state, due to the existence of the rounded corner or the arc surface, gaps exist between the first protective cover 100 and the second protective cover 200 and the housing 30, respectively. In another embodiment, in the first state, there may be a gap between each of the first bottom surface 140 and the second bottom surface 240 and the first end surface 33.

As shown in fig. 6a to 6c, in an embodiment, a first groove 101 is formed in the first protective cover 100, and the first groove 101 is formed at the intersection of the first bottom surface 140 and the first outer surface 110. The housing 30 defines a second recess 102, and the second recess 102 is defined at the intersection of the first end surface 33 and the first surface 31. The flexible member 70 has a strip structure, one side of which is connected to the first recess 101, and the other side of which is connected to the second recess 102, and fills the gap between the first protective cap 100 and the housing 30. As shown in fig. 1 and 4, in an embodiment, in the first state, the first outer surface 110, the outer surface of the flexible member 70, and the first surface 31 are substantially flush, so that the first protective cover 100, the flexible member 70, and the housing 30 are in a complete structure and the pins 60 are prevented from being exposed through the gaps. In the second state, the flexible member 70 is exposed to the working mating surface 90.

In one embodiment, the number of the flexible members 70 is 2, and the flexible members are symmetrically disposed on two opposite sides of the housing 30. I.e., the flexible member 70 is also provided between the second protective cover 200 and the case 30 to fill the gap between the second protective cover 200 and the case 30, so that the second protective cover 200, the flexible member 70 and the case 30 assume a complete structure in the first state.

As shown in fig. 1 and 4, in an embodiment, the number of the hinge assemblies is 4, 2 hinge assemblies are connected between the first protection cover 100 and the housing 30, and the 2 hinge assemblies are close to both sides of the first protection cover 100 in the X direction, one of the flexible members 70 is located between the 2 hinge assemblies, and both ends of the flexible member 70 are respectively close to the 2 hinge assemblies. Another 2 hinge assemblies are connected between the second protection cover 200 and the housing 30, and the other 2 hinge assemblies are close to both sides of the second protection cover 200 in the X direction, and then another flexible member 70 is located between the other 2 hinge assemblies, and both ends of the flexible member 70 are respectively close to the 2 hinge assemblies.

As shown in FIGS. 4 and 5, in one embodiment, the flexible member 70 is a sheet-like planar structure, flexible, foldable and malleable such that the first and second

protective caps

100, 200 can be switched between the first and second states. In the second state, the surface of the flexible member 70 is flush or has a height difference with the working mating surface 90.

In another embodiment, as shown in fig. 10 and 11, the flexible member 70 is a generally sheet-like structure. Specifically, the flexible member 70 has a creased folded structure. The fold allows the flexible member 70 to open and fold, facilitating rotation of the first protective cap 100 and the second protective cap 200. In addition, in the second state, the folding structure 70 is exposed, so that the appearance expression of the power adapter 10 can be increased, and the power adapter 10 is more beautiful and has a design feeling.

In one embodiment, when the power adapter 10 is located between the first state and the second state, for example, the first protective cover 100 and the second protective cover 200 are respectively in a half-open state (a state after the first protective cover 100 and the second protective cover 200 are rotated 90 ° from the first state), the user holds the housing 30 with the hand, and the first protective cover 100 and the second protective cover 200 abut against the fingers of the user. Because the 2 flexible pieces 70 are respectively filled in the gap between the first protective cover 100 and the housing 30 and the gap between the second protective cover 200 and the housing 30, the flexible pieces 70 block the transmission path of the current between the plug pin 60 and the finger of the user, so that the creepage distance between the plug pin 60 and the finger of the user cannot exist, and the electric shock condition is avoided when the user inserts the power adapter 10 into an external power supply.

As shown in fig. 4, in an embodiment, the first inner housing of the first protective cover 100 defines a first engaging groove 121, the first engaging groove 121 extends to the first inner surface 120, and the shape of the first engaging groove 121 is similar to the shape of the plug 60; the second inner shell of the second protective cover 200 is formed with a second slot 221, the second slot 221 extends to the second inner surface 220, and the shape of the second slot 221 is similar to the shape of the pin 60. In the first state, the first card slot 121 and the second card slot 221 are in communication, and the pins 60 can be received in the first card slot 121 and the second card slot 221. In one embodiment, the first slot 121 extends to the first bottom surface 140 in the Y direction, which is the length direction of the pin 60, but is spaced from the first top surface 130; the second card slot 221 extends to the second bottom surface 240, but is spaced from the second top surface 230; the pins 60 of the power adapter 10 are completely hidden and not exposed in the first state, and the appearance of the power adapter 10 is a cuboid or a cube, so that the appearance integrity of the power adapter 10 is ensured. In another embodiment, in the length direction of the pin 60, i.e., the Y direction, the first card slot 121 extends to the first bottom surface 140 and the first top surface 130, and the second card slot 221 extends to the second bottom surface 240 and the second top surface 230; that is, the first protective cover 100 and the second protective cover 200 are equal to the protruding length of the plug pins 60 from the housing 30, and in the first state of the power adapter 10, the plug pins 60 are flush with the first top surface 130 and the second top surface 230, respectively, so that the power adapter 10 has a smaller length, is thinner and lighter, and is convenient to carry.

It will be appreciated that the first card slot 121 extends to the first bottom surface 140 and the second card slot 221 extends to the second bottom surface 240, but the working mating surface 90 is defined as the surface formed by the first bottom surface 140, the first end surface 33 and the second bottom surface 240 in the second state when the first card slot 121 and the second card slot 221 are omitted. When the number of the protective covers 20 is 1, the working engagement surface 90 is defined as a surface formed by the first bottom surface 140 and the first end surface 33 in the second state when the first card slot 121 is omitted.

In one embodiment, the number of the pins 60 is 2, and the number of the first card slots 121 and the number of the second card slots 221 are 2. In another embodiment, the number of the pins 60 is 1, 3 or more, and the number of the first card slots 121 and the second card slots 221 corresponds to the number of the pins 60. The shape of the pin 60 may be cylindrical or flat, and is not particularly limited herein.

In another embodiment, the first protective cap 100 is a hollow open box structure, and the second protective cap 200 is a hollow open box structure. In the first state, the first protective cap 100 and the second protective cap 200 form a closed inner space, the pins 60 are accommodated in the inner space formed by the first protective cap 100 and the second protective cap 200, and the number of the pins 60 is not limited.

In an embodiment, as shown in fig. 2 and 8, in the second state of the power adapter 10, compared with the first state, the first protective cover 100 and the second protective cover 200 are respectively rotated by about 180 ° around the width direction of the power adapter 10, that is, when the power adapter 10 is in the first state, the first protective cover 100 and the second protective cover 200 are rotated by 180 ° relative to the housing 30, so that the first outer surface 110 is attached to and fixed to the first surface 31, the second outer surface 210 is attached to and fixed to the second surface 32, and the power adapter 10 is in the second state.

As shown in fig. 4 and 8, in an embodiment, the number of the pins 60 is 2, 2 pins 60 are arranged in the width direction of the power adapter 10, i.e., the X direction, the distance between each of the 2 pins 60 and the first surface 31 is L1, and the distance between each of the 2 pins 60 and the second surface 32 is L2. In the second state of the power adapter 10, the distance between each of the 2 pins 60 and the first inner surface 120 is L3, and L3 is equal to the sum of the thickness of the first protective cover 100 and L1; the distance between the 2 pins 60 and the second inner surface 220 is L4, and L4 is equal to the sum of the thickness of the second protective cover 200 and L2. In the second state, the distance between the pin 60 and the edge of the working mating face 90 is the minimum of L3, L4.

It can be understood that, when the number of the protective covers 20 is 1, in the second state, the distance from the pin 60 to the surface of the housing 30 facing away from the protective cover 20, and the distance from the pin 60 to the surface of the protective cover 20 facing away from the housing 30, the minimum value of the two distances is greater than the preset value. When the protective cover 20 includes the first protective cover 100 and the second protective cover 200, in the second state, when the distance from the pin 60 to the edge of the power adapter 10 in the X direction is greater than the distance from the pin 60 to the edge of the power adapter 10 in the Z direction, the minimum value of the distances from the pin 60 to the plane where the first inner surface 120 is located and from the pin 60 to the plane where the second inner surface 220 is located needs to be greater than the preset value.

The safety specification, i.e., the safety specification, specifies that the distance from the pins 60 to the edge of the working mating surface 90 in the second state of the power adapter 10 is not less than a preset value. In some embodiments, the preset value may be 6.5mm, or may be other data, which is determined according to the usage of the power adapter 10. It is understood that, in the second state, in the thickness direction of the power adapter 10, i.e., the Z direction, the distance from the pins 60 to the edge of the working mating face 90 is not less than the preset value; and the distance from the pins 60 to the edge of the working mating face 90 in the width direction of the power adapter 10, i.e., the X direction, is not less than a preset value.

L1 is smaller than a preset value, such as 2.65mm, and L3 is not smaller than a preset value, such as 8.4 mm.

In another embodiment, L1 is not equal to L2, that is, 2 pins 60 are asymmetrically arranged on the first end face 33, for example, when 2 pins 60 are close to the first surface 31, L1 is smaller than L2, L3 is smaller than L4, the minimum value of the edge of each pin 60 from the working mating face 90 is L3, and L3 is not smaller than the preset value; for another example, when 2 pins 60 are close to the second surface 32, L1 is greater than L2, L3 is greater than L4, the minimum value of the edge of the pin 60 from the working mating surface 90 is L4, and L4 is not less than the preset value. In this embodiment, both L1 and L2 are less than the preset value, and neither L3 nor L4 are less than the preset value.

In an embodiment, in the second state, there is a height difference between the first bottom surface 140 and the first end surface 33 within a set range, such as not greater than 2mm, such as 1 mm. The first bottom surface 140 may be higher than the first end surface 33 or lower than the first end surface 33. The minimum distance from any one position of the pin 60 to the plane of the first inner surface 120 is not less than a preset value, i.e. the minimum distance is the same as the minimum distance without height difference, and is the minimum value of L3 and L4, and the minimum value of L3 and L4 is greater than the preset value. The minimum distance between the pins 60 and the second inner surface 220 is equal to or greater than a predetermined value. In the second state, first protective cap 100 is attached to housing 30, and the attachment includes the three cases explained above, i.e. completely attached to no gap, a gap within 2mm or other size range, and a gap partially attached to a portion. When the gap exists between the first protective cover 100 and the housing 30, the minimum distance between any one portion of the pin 60 and the plane where the first inner surface 120 is located needs to be greater than a predetermined value. The minimum distance between the pins 60 and the plane of the second inner surface 220 is greater than a predetermined value.

In the first state of the power adapter 10, the thickness of the power adapter 10 is the sum of L1 and L2. Both L1 and L2 are smaller than the preset values, and when L1 and L2 are smaller, the thickness of the power adapter 10 is smaller. The thin power adapter 10 is beautiful in appearance, scientific in sense, and portable. The power adapter 10 can satisfy the safety requirements in the second state. Namely, the power adapter 10 of the present application has a small thickness in the first state, and is convenient to carry; the provision of the flexible member 70 provides the power adapter 10 with appearance integrity in the first state.

The first rotating shaft 52 is inserted through the rotating shaft base 51 and the first mounting base 54, so that the first mounting base 54 can rotate relative to the rotating shaft base 51 around the first rotating shaft 52. The second rotating shaft 53 penetrates through the rotating shaft seat 51 and the second mounting seat 55, so that the second mounting seat 55 can rotate around the second rotating shaft 53 relative to the rotating shaft seat 51.

seats

In the specific example shown in fig. 23, the first protective cover 100 and the second protective cover 200 are in the first state, at this time, the first protective cover 100 and the second protective cover 200 are located directly above the housing 30, the first rotating shaft 52 is located directly above the second rotating shaft 53, the first protective cover 100 and the second protective cover 200 are separated in a direction away from each other, that is, the first protective cover 100 is turned over to the left, the second protective cover 200 is turned over to the right, and at this time, the first mounting seat 54 and the rotating shaft seat 51 can synchronously rotate around the second rotating shaft 53 relative to the housing 30. Referring to fig. 24, the first mounting seat 54 and the rotating shaft seat 51 rotate around the second rotating shaft 53 by 90 ° synchronously relative to the housing 30, at this time, the first protective cover 100 and the second protective cover 200 are in a transition state between the first state and the second state, and then, the housing 30 and the rotating shaft seat 51 are relatively stationary, and the first mounting seat 54 rotates around the first rotating shaft 52 relative to the housing 30 and the rotating shaft seat 51. Referring to fig. 25, the first mounting seat 54 is rotated by 90 ° around the first rotating shaft 52 relative to the housing 30 and the rotating shaft seat 51, and at this time, the first protective cover 100 and the second protective cover 200 are in the second state, and the first rotating shaft 52 and the second rotating shaft 53 are located at the same horizontal height.

It should be noted that the above-mentioned operation principle is not the only operation state of the second hinge assembly 50, but is an ideal operation state set forth for clarity, and in fact, during the operation of the second hinge assembly 50, the first mounting seat 54 is likely to rotate around the first rotating shaft 52 relative to the rotating shaft seat 51, and simultaneously, the rotating shaft seat 51 is also likely to move around the second rotating shaft 53 relative to the housing 30, so that the switching from the first state to the second state can be realized. Similarly, the opposite operation can be used to know the operation process of rotating the first protective cover 100 and the second protective cover 200 from the second state to the first state, which is not described herein. In addition, in order to avoid interference between the rotating shaft seat 51 and the housing 30, it is ensured that the first outer surface 110 and the second outer surface 210 can be respectively attached to the first surface 31 and the second surface 32 in the second state, and the avoiding notch 511 can be provided on the rotating shaft seat 51.

It will be appreciated that the position and number of hinge assemblies may be specifically set and selected according to the actual requirements.

The first protective cover 100 and the housing 30 can be connected by 2 hinge assemblies, and the 2 hinge assemblies are respectively located at or near two ends of the power adapter 10 in the width direction, i.e., the X direction. The second protective cover 200 may also be coupled to the housing 30 by 1 hinge assembly or 2 hinge assemblies, and the positions of the hinge assemblies may be the same as or different from the positions of the hinge assemblies coupled between the first protective cover 100 and the housing 30.

As shown in fig. 4 and fig. 6a, in an embodiment, a fifth magnetic body 125 is disposed in the first protective cover 100, and a sixth magnetic body 225 is disposed in the second protective cover 200. There is a magnetic force of mutual attraction between the fifth magnetic body 125 and the sixth magnetic body 225, so that there is a magnetic force of mutual attraction between the first protective cover 100 and the second protective cover 200. In the first state, the first protective cover 100 and the second protective cover 200 are magnetically attracted and attached to each other by the magnetic force of the mutual attraction between the fifth magnetic body 125 and the sixth magnetic body 225. In the second state, the first protective cover 100 and the second protective cover 200 are magnetically attracted and respectively attached to the two opposite sides of the housing 30 through the mutually attracted magnetic force between the fifth magnetic body 125 and the sixth magnetic body 225. In one embodiment, the fifth magnetic body 125 and the sixth magnetic body 225 are both magnets. In another embodiment, one of the fifth magnetic body 125 and the sixth magnetic body 225 is a magnet, and the other of the fifth magnetic body and the sixth magnetic body can be magnetically attracted by the magnet, such as a common iron block.

In another embodiment, the fifth magnetic element 125 may be located on the first outer surface 110 of the first protective cover 100, and the sixth magnetic element 225 may be located on the second outer surface 210 of the second protective cover 200, which also enables the first protective cover 100 and the second protective cover 200 to have attractive magnetic force.

As shown in fig. 1 and 2, in the first state of the power adapter 10, the first protective cover 100 and the second protective cover 200 are magnetically fixed by the fifth magnetic body 125 and the sixth magnetic body 225, and the magnetic force of the fifth magnetic body 125 and the sixth magnetic body 225 passes through the first inner surface 120 and the second inner surface 220. When a user places the plug pins 60 in a pocket or a trunk, the first protective cover 100 and the second protective cover 200 hide the plug pins 60 to prevent the plug pins 60 from scratching surrounding objects, and the first protective cover 100 and the second protective cover 200 are not easily opened, so that the power adapter 10 can reliably hide the plug pins 60 during storage or transportation.

As shown in fig. 2, 7 and 8, in one embodiment, the magnetic forces of the mutual attraction between the fifth and sixth

magnetic bodies

125 and 225 include a first magnetic force F1 and a second magnetic force F2. The first magnetic force F1 passes through the first inner surface 120 and the second inner surface 220 such that the first protective cap 100 and the second protective cap 200 have a tendency to rotate to the first state; the second magnetic force F2 passes through the first outer surface 110, the second outer surface 210, and the housing 30 such that the first protective cover 100 and the second protective cover 200 have a tendency to rotate to the second state.

In the first state of the power adapter 10, the first protective cover 100 and the second protective cover 200 are tightly attracted and do not open by the first magnetic force F1 between the fifth magnetic body 125 and the sixth magnetic body 225. When the first protective cover 100 and the second protective cover 200 need to be opened, the user needs to apply a force to the first protective cover 100 or the second protective cover 200 to overcome the first magnetic force F1 between the fifth magnetic body 125 and the sixth magnetic body 225, so that the first protective cover 100 or the second protective cover 200 can rotate relative to the housing 30. There exists a critical angle α, which is the angle between the first or second

protective cap

100 or 200 and the housing 30, i.e., the angle between the first outer surface 110 and the plane of the first surface 31, or the angle between the second outer surface 210 and the plane of the second surface 32. When one of the first protective cover 100 and the second protective cover 200 is in the first state or the second state, and an angle between the other of the first protective cover 100 and the second protective cover 200 and the housing 30 is the critical angle α, the first magnetic force F1 and the second magnetic force F2 are in a balanced state, that is, the first magnetic force F1 and the second magnetic force F2 interact with each other to make the first protective cover 100 and the second protective cover 200 in a balanced state. When one of the first protective cover 100 and the second protective cover 200 is in the second state and the angle between the other of the first protective cover 100 and the second protective cover 200 and the housing 30 is greater than the critical angle α, the first magnetic force F1 is greater than the second magnetic force F2, and the first protective cover 100 and the second protective cover 200 can automatically return to the first state. When one of the first protective cap 100 and the second protective cap 200 is in the first state and the angle between the other of the first protective cap 100 and the second protective cap 200 and the housing 30 is smaller than the critical angle α, the first magnetic force F1 is smaller than the second magnetic force F2, and the first protective cap 100 and the second protective cap 200 can automatically return to the second state.

Assuming a user applies a force to the first cap 100, the first cap 100 rotates and the second cap 200 remains stationary. At this time, the first magnetic force F1 is greater than the second magnetic force F2, such that the first protective cover 100 and the second protective cover 200 have a tendency to return to the first state. When the first protective cover 100 is rotated from the first state and the angle between the first protective cover 100 and the housing 30 is not reached to the critical angle α, the first magnetic force F1 is gradually weakened, the second magnetic force F2 is gradually strengthened, and the first magnetic force F1 is greater than the second magnetic force F2, so that the first protective cover 100 and the second protective cover 200 have a tendency to return to the first state. When the first protective cover 100 rotates to an angle with the housing 30, which is the critical angle α, the first magnetic force F1 and the second magnetic force F2 are in a balanced state, so that the first protective cover 100 and the second protective cover 200 can be in a balanced state, and ideally, the first protective cover 100 and the second protective cover 200 can remain stationary in the balanced state. As the user continues to apply force, the first magnetic force F1 continues to decrease, the second magnetic force F2 continues to increase, but the first magnetic force F1 is always less than the second magnetic force F2, the user may stop applying force to the first protective cover 100, and the second magnetic force F2 causes the first protective cover 100 and the second protective cover 200 to automatically rotate relative to the housing 30 until the first protective cover 100 and the second protective cover 200 are attached to the housing 30. When the power adapter 10 is in the second state and a user uses the power adapter 10 to supply power to an electronic component, the first protective cover 100 and the second protective cover 200 are fixedly attached to the housing 30 and do not shake or rotate, which is convenient for use. It is understood that when the power adapter 10 needs to be opened, the user can also choose to apply a force to the second protection cover 200, and the power adapter 10 can be opened as well, and the operation principle is the same as the manner in which the user applies a force to the first protection cover 100.

As shown in fig. 2, 7 and 8, in an embodiment, when the power adapter 10 is in the second state, the first protective cover 100 and the second protective cover 200 are tightly attracted and do not open by the second magnetic force F2 between the fifth magnetic body 125 and the sixth magnetic body 225. When it is desired to close the power adapter 10, the user applies a force to the first protection cover 100 or the second protection cover 200 to overcome the second magnetic force F2 between the fifth magnetic body 125 and the sixth magnetic body 225, so that the first protection cover 100 or the second protection cover 200 can rotate relative to the housing 30. Assume that the user applies a force to the first protective cap 100, the first protective cap 100 is separated from the housing 30 and rotated, and the second protective cap 200 is kept in a state of being attached to the housing 30. As the first protective cover 100 rotates, the second magnetic force F2 weakens, the first magnetic force F1 gradually increases, but the second magnetic force F2 is always greater than the first magnetic force F1. When the first protective cover 100 rotates to the critical angle α with the housing 30, the first magnetic force F1 and the second magnetic force F2 are in a balanced state, that is, the first protective cover 100 and the second protective cover 200 are in a balanced state under the combined action of the first magnetic force F1 and the second magnetic force F2, and ideally, the first protective cover 100 and the second protective cover 200 can be in a static state. As the user continues to apply force to the first protective cover 100, the equilibrium between the first and second magnetic forces F1 and F2 is broken such that the first magnetic force F1 is greater than the second magnetic force F2, and the user may stop applying force to the first protective cover 100. The first magnetic force F1 can cause the first protective cover 100 and the second protective cover 200 to automatically rotate relative to the housing 30 until the first protective cover 100 and the second protective cover 200 are attached to each other, so that the power adapter 10 is in the first state. In the first state, the power adapter 10 is tightly fixed between the first protective cover 100 and the second protective cover 200 during storage, transportation, daily placement and movement, and has the reliability of hiding the plug pins 60, and the thickness is thin, so that the power adapter is convenient to carry. It is understood that when the power adapter 10 needs to be closed, the user can also choose to apply force to the second protection cover 200, and the power adapter 10 can be closed similarly, and the operation principle is the same as the way that the user applies force to the first protection cover 100.

In one embodiment, part or all of the structure of the first protective cap 100 is made of a magnetic material, and part or all of the structure of the second protective cap 200 is made of a magnetic material, such that there is an attractive magnetic force between the first protective cap 100 and the second protective cap 200. Thereby, the automatic opening and the automatic closing between the first protection cover 100 and the second protection cover 200 can be realized, and the principle is the same, which is not described herein again.

In one embodiment, some or all of the structure of the cap 20 is made of a magnetic material and some or all of the structure of the housing 30 is made of a magnetic material, such that there is an attractive magnetic force between the cap 20 and the body. For example, the first protective cover 100 and the second protective cover 200 are made of magnetic materials, and there is an attractive magnetic force between the two, so that the first state of the power adapter 10 can be maintained; part of the structure of the housing 30 is made of a magnetic material, so that there is an attractive magnetic force between the first protective cover 100 and the housing 30, and an attractive magnetic force between the second protective cover 200 and the housing 30, so that the second state of the power adapter 10 can be maintained. The automatic opening and closing of the first protective cover 100 and the second protective cover 200 can also be achieved, and the principle is the same, and will not be described herein again.

In one embodiment, a method for manufacturing a power adapter 10 is provided, which includes the following steps:

providing a pin 60, a first shell 301, a second shell 302, a hinge assembly, a first protective cover 100 and a second protective cover 200, wherein a magnetic force exists between the first protective cover 100 and the second protective cover 200;

fixing the pins 60 to the first case 301;

fixing the first case 301 and the second case 302 to form the housing 30; and

the first protective cover 100 and the second protective cover 200 are respectively connected to the two opposite sides of the housing 30 in a rotating manner;

the first protective cover 100 and the second protective cover 200 have a first state and a second state relative to the housing 30, in the first state, the first protective cover 100 and the second protective cover 200 are attached and fixed, and at least part of the structure of the pin 60 is covered by the first protective cover 100 and the second protective cover 200; in the second state, the first protective cover 100 and the second protective cover 200 are respectively attached to and fixed on two sides of the housing 30.

In one embodiment, the pins 60 are fixed with the first housing 301, or the pins 60 and the first housing 301 fixed as one body are directly purchased. The pins 60 and the first housing 301 may be formed as a unitary structure by in-mold injection molding. The first shell 301 and the second shell 302 are then fixed by dispensing or ultrasonic heat fusion or other processes to form the housing 30. It can be understood that the first shell 301 is opened with 4 second receiving grooves 331, and in other embodiments, the number and positions of the second receiving grooves 331 are changed according to actual needs.

In one embodiment, four hinge assemblies are respectively fixed in the 4 second receiving grooves 331. The hinge assembly can be adhered to the second receiving groove 331 by dispensing or fixed to the second receiving groove 331 by mechanical fixing.

In one embodiment, the fifth magnetic body 125 and the sixth magnetic body 225 are respectively installed in the first protective cover 100 and the second protective cover 200, so that the first protective cover 100 and the second protective cover 200 have mutually attractive magnetic forces.

In one embodiment, the first protective cap 100 and the second protective cap 200 are mounted to the housing 30, respectively. Specifically, the hinge assemblies are respectively fixed in the first receiving grooves 141 of the first protective cover 100 and the second protective cover 200, so that the first protective cover 100 and the second protective cover 200 are respectively rotatably connected with the housing 30 through the hinge assemblies.

As shown in fig. 2, 7 and 8, in one embodiment, the fifth magnetic body 125 is fixed in the first protective cover 100, and the sixth magnetic body 225 is fixed in the second protective cover 200. When the power adapter 10 is in the first state, the second magnetic force F2 between the fifth magnetic body 125 and the sixth magnetic body 225 is greater than the first magnetic force F1 after the first protective cover 100 or the second protective cover 200 is opened by the critical angle α based on the principle of the magnetic fields of the fifth magnetic body 125 and the sixth magnetic body 225, so that the first protective cover 100 and the second protective cover 200 are automatically opened and can be always kept in the opened state. Similarly, when the power adapter 10 is in the second state, after the first protective cover 100 or the second protective cover 200 is closed to the critical angle α, the second magnetic force F2 between the fifth magnetic body 125 and the sixth magnetic body 225 is smaller than the first magnetic force F1, and the first protective cover 100 and the second protective cover 200 are also automatically closed and maintained in the first state by the magnetic force.

The thickness of the power adapter 10 is thin, and the pins 60 do not occupy the space inside the housing 30, so that the size of the housing 30 can be reduced, the overall size of the power adapter 10 can be reduced, and the power adapter is highly portable. In the non-use state, the power adapter 10 can be placed in the first state, the pins 60 are hidden, portability is achieved, and the pins 60 do not damage surrounding objects. Under the second state of the power adapter 10, the first protective cover 100 and the second protective cover 200 are attached to the housing 30, so that the power adapter 10 meets the safety requirements. By using the magnetic field characteristics of the fifth magnetic body 125 and the sixth magnetic body 225, after the first protective cover 100 or the second protective cover 200 is opened or closed to the critical angle α, the first protective cover 100 and the second protective cover 200 can be automatically opened or closed together, thereby improving the user experience.

In the first state, the protective cover 20 covers the end of the housing 30, and at least a portion of the pins 60 can be accommodated in the protective cover 20. The pins 60 may be entirely received in the cover 20 or partially exposed. In the second state, the protective cover 20 is opened and stacked on one side of the body, and the protective cover 20 is attached to the surface of the body. The fitting is understood to mean that there is no gap between the two, or that there may be a small gap. The distance from the pins 60 to the surface of the side of the protective cover 20 facing away from the housing 30 is not less than the preset value, and the distance from the pins 60 to the surface of the side of the housing 30 facing away from the protective cover 20 is not less than the preset value, so that the power adapter 10 meets the safety specification requirements.

When the number of the protective covers 20 is 1, in the second state, when a height difference exists between the protective covers 20 and the first end faces 33, such as not more than 2mm, the distance from the pins 60 to the edge of the working mating face 90 is the same as that when no height difference exists; in the second state, when there is a gap between the protective cover 20 and the housing 30, for example, not greater than 2mm, the distance from the pin 60 to the edge of the working engagement surface 90 is the same as the above, i.e., the minimum distance from any point of the pin 60 to the surface of the working engagement surface 90 along the Y direction.
