[0055] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0056] As Figure 1 and Figure 2 shown, in an embodiment, a power adapter 10 is provided. A power adapter includes a body and a connecting member 20. The body includes a housing 30 and pins 40. The housing 30 has a first surface 33, and the pins 40 protrude from the first surface 33. The connecting member 20 has a second surface 140 connected to the housing 30, and the second surface 140 and the first surface 33 can form a working mating surface 90 (shown in Figure 7a ). In an embodiment, the distance between the pins 40 and the edge of the working mating surface 90 is not less than a preset value, such as 5.1 mm or 6.5 mm or 7.9 mm, so that the power adapter 10 can meet the safety regulations requirements.

[0057] For the power adapter 10 of this embodiment of the present application, by forming the working mating surface 90 through the second surface 140 and the first surface 33, the pins 40 can meet the usage state. Since the pins 40 do not need to occupy the space inside the housing 30, the size of the housing 30 can be reduced, thereby reducing the overall volume of the power adapter 10, and the portability is good. For the power adapter 10 in the embodiment of the present application, due to the provision of the connecting member 20, the connecting member 20 and the housing 30 can be cooperated to form the working mating surface 20 to meet the usage requirements of the power adapter 10 (such as, safety regulations requirements), so that the thickness of the housing 30 itself can be set to be smaller (such as, much smaller than the above-mentioned preset value), and the overall volume of the power adapter 10 can be greatly reduced compared with the volume of the power adapter in the related art.

[0058] In one embodiment, the connector 20 can move relative to the housing 30 and be received inside the housing 30 or separated from the housing 30. When the connector 20 is received in the housing 30, it moves relative to the housing 30 and can move to fit the outer surface of the housing 30. The second surface 140 is flush with the first surface 33 to form a working mating surface 90. The user can insert the pin 40 into an external power supply, and the working mating surface 90 can cooperate with or be in contact with the surface of the external power supply.

[0059] It can be understood that the working mating surface 90 is the surface of the power adapter 10 that fits or is close to the external power supply when the power adapter 10 is electrically connected to the external power supply. When the connector 20 is separated from the housing 30, the connector 20 can be attached to the outer surface of the housing 30, and the second surface 140 is flush with the first surface 33 to form the working mating surface 90. The specific fixing method can be magnetic attraction or snap connection. In one embodiment, in the first state, the connector 20 is received inside one end of the housing 30 away from the pin 40, and the connector 20 is slidable so that the connector 20 slides out of the housing 30; the connector 20 can also move to fit the outer surface of the housing 30, and the second surface 140 is flush with the first surface 33. The specific moving method can adopt the settings in the mechanical field that can achieve this function, and will not be exemplified one by one here.

[0060] It can be understood that all "flush" described in the embodiments of the present application can also be "substantially flush", that is, the flush can be completely in one plane or there can be a height difference within a certain range. For example, the height difference between the second surface 140 and the first surface 33 is not greater than 2 mm or 5 mm or not greater than 10 mm or other dimensions, such as the height difference is not greater than 1 mm, and this situation is also within the protection scope of the present application. For example, when two surfaces are flush, it can mean that the two surfaces are completely in one plane or there can be a height difference within a certain range between the two surfaces.

[0061] In another embodiment, the second surface 140 and the first surface 33 together form the working mating surface 90, but there is a height difference between the second surface 140 and the first surface 33, and the height difference is within a set range, and the set range can be not greater than 2 mm, such as 1 mm.

[0062] As Figures 1 to 4 shown, in another embodiment, the connector 20 and the housing 30 are connected by a hinge assembly, and the connector 20 can rotate relative to the housing 30 to have a first state and a second state. In the first state, at least part of the structure of the pin 40 is received in the connector 20. In the second state, the second surface 140 is flush with the first surface 33 or there is a height difference within a set range to form the working mating surface 90.

[0063] As Figures 1 to 4As shown, in another embodiment, the connector 20 can rotate relative to the housing 30, such that the power adapter 10 has a first state and a second state. In the first state, the connector 20 covers the housing 30, and at least part of the structure of the pin 40 is received within the connector 20; in the second state, the end face of the connector 20 connected to the housing 30 is flush with the first surface 33, and a working mating surface 90 is formed. It can be understood that being flush can be completely in one plane or there can be a height difference within a certain range. For example, the height difference between the end face of the connector 20 connected to the housing 30 and the first surface 33 is not greater than 2 mm or 5 mm or not greater than 10 mm or other dimensions, such as the height difference is not greater than 1 mm, and this situation is also within the protection scope of this application. In another embodiment, the end face of the connector 20 connected to the housing 30 and the first surface 33 together form the working mating surface 90, but there is a height difference between the end face of the connector 20 connected to the housing 30 and the first surface 33, and the height difference is within a set range, and the set range can be not greater than 2 mm, such as 1 mm. A receiving space is provided within the housing 30, and a circuit board is provided within the receiving space. The circuit board is electrically connected to the pin 40. In one embodiment, the housing 30 has a cuboid or cube structure, and the edges of the housing 30 can be smoothly transitioned, such that the power adapter 10 has no convex edges and has a good feel. In other embodiments, the body can also have a cylindrical structure or other structures, which are not specifically limited herein.

[0064] As Figures 1 to 4 shown, in one embodiment, the connector 20 includes a first connector 100 and a second connector 200. In the first state, the first connector 100 and the second connector 200 are attached and fixed. In the second state, the first connector 100 and the second connector 200 are respectively attached and fixed to the opposite sides of the housing 30.

[0065] As Figures 1 to 4 shown, in one embodiment, the connector 20 includes a first connector 100 and a second connector 200, both of which are fixed to the edge of one end of the housing 30, and the first connector 100 and the second connector 200 are respectively fixed to the opposite sides of the housing 30. The pin 40 is fixed to the end of the housing 30 and is located at the same end as the first connector 100 and the second connector 200. The housing 30 is provided with a charging interface 341, and the charging interface 341 and the pin 40 are respectively located at the opposite ends of the housing 30. An external electronic component can pass through the charging interface 341 to be electrically connected to the circuit board, and thus be electrically connected to the pin 40. After the power adapter 10 is electrically connected to a power source, the power source can supply power to the electronic component. It can be understood that the electronic component can be an intermediate connecting line such as a data cable, or 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 cable, which is not limited herein.

[0066] As Figures 1 to 4 shown, in one embodiment, the power adapter 10 includes a length direction, i.e., the Y direction, a width direction, i.e., the X direction, and a thickness direction, i.e., the Z direction. The pin 40 extends along the length direction of the power adapter 10, i.e., the Y direction, that is, the length direction of the pin 40 is the Y direction. The housing 30 includes a fourth surface 31 and a fifth surface 32 that are arranged opposite to each other, a first side surface 35 and a second side surface 36 that are arranged opposite to each other, and a first surface 33 and a tenth surface 34 that are arranged opposite to each other. The fourth surface 31 and the fifth surface 32 define the thickness direction of the power adapter 10, i.e., the Z direction. The first side surface 35 and the second side surface 36 define the width direction of the power adapter 10, i.e., the X direction. The first surface 33 and the tenth surface 34 define the length direction of the housing 30, and the length direction of the power adapter 10, i.e., the Y direction, is the same as the length direction of the housing 30. The pin 40 extends out of the housing 30 along the length direction of the power adapter 10. In another embodiment, the pin 40 may also extend along the width direction of the power adapter 10, and corresponding designs can be made according to the actual requirements of the power adapter 10.

[0067] There are chamfers between adjacent surfaces of the housing 30 and the transition is smooth, so that the power adapter 10 has a smooth and round feel. The pin 40 is fixed and protrudes from the first surface 33. The first connector 100 is fixed at the junction of the first surface 33 and the fourth surface 31, and the second connector 200 is fixed at the junction of the first surface 33 and the fifth surface 32. It can be understood that chamfers may or may not be provided between the first surface 33 and adjacent surfaces.

[0068] As Figure 5 shown, in one embodiment, the material of the housing 30 is plastic. The housing 30 includes a first housing 300 and a second housing 400, and the pin 40 is fixed to the first housing 300. The first housing 300 and the second housing 400 are fixed by ultrasonic heat melting or other processes. The pin 40 and the first housing 300 are integrally formed by in-mold injection, and the first housing 300 is provided with a second receiving groove 331 for the subsequent installation of the hinge assembly. It can be understood that after the first housing 300 and the second housing 400 are assembled together, the fourth surface 31, the fifth surface 32, the first side surface 35, and the second side surface 36 are formed.

[0069] As Figure 5 and Figure 6As shown, in one embodiment, the first connector 100 includes a third surface 110 and a sixth surface 120 disposed opposite to each other, a first top surface 130 and a second surface 140 disposed opposite to each other, and a first left side surface 150 and a first right side surface 160 disposed opposite to each other. The adjacent surfaces of the first connector 100 can be smoothly transitioned, so that the first connector 100 has a smooth feel. It can be understood that a chamfer can be provided between the second surface 140 and the adjacent surface for smooth transition, or no chamfer can be provided. The second connector 200 includes a seventh surface 210 and an eighth surface 220 disposed opposite to each other, a second top surface 230 and a ninth surface 240 disposed opposite to each other, and a second left side surface 250 and a second right side surface 260 disposed opposite to each other. The adjacent surfaces of the second connector 200 can be smoothly transitioned, so that the second connector 200 has a smooth feel. It can be understood that a chamfer can be provided between the ninth surface 240 and the adjacent surface for smooth transition, or no chamfer can be provided.

[0070] As Figure 3 , Figure 6 and Figure 7a shown, in one embodiment, the first connector 100 and the second connector 200 can rotate relative to the housing 30 about the width direction of the power adapter 10, so that the first connector 100 and the second connector 200 have a first state and a second state, that is, the power adapter 10 has a first state and a second state. In another embodiment, the first connector 100 and the second connector 200 can also rotate relative to the housing 30 about the length direction of the power adapter 10. As Figure 7a shown, in the second state, the first connector 100 and the second connector 200 are separated from each other. The first connector 100 is attached to one side of the housing 30, and the second connector 200 is attached to the other side of the housing 30. The end faces of the first connector 100 and the second connector 200 connected to the housing 30 are flush with the end face of the housing 30 where the pins 40 are provided, that is, both the second surface 140 and the ninth surface 240 are flush with the first surface 33. The second surface 140, the ninth surface 240 and the first surface 33 together form a working mating surface 90, and the pins 40 are exposed. The user can insert the pins 40 into the power supply, and the working mating surface 90 is attached to the power supply. It can be understood that being flush can be completely in one plane, or there can be a height difference within a certain range. For example, the height difference between the end faces of the first connector 100 and the second connector 200 connected to the housing 30 and the first surface 33 is not greater than 2 mm or 5 mm or not greater than 10 mm or other dimensions, such as 1 mm. This situation is also within the protection scope of this application.

[0071] In the embodiments of the present application, all "fittings" described may be approximate fittings, that is, the fittings described in the embodiments of the present application include at least the following situations: In the first situation, the two surfaces being fitted are completely in close contact without gaps; in the second situation, there are gaps between the two surfaces being fitted. For example, the gaps between the first connecting member 100 and the second connecting member 200 and the surfaces on both sides of the housing 30 are not greater than 1 mm or 2 mm or other dimensions. This situation is also within the protection scope of the present application. The two surfaces being fitted may be parallel or not parallel; in the third situation, the two surfaces being fitted are in partial contact, that is, the two surfaces being fitted are not completely in close contact, but are in partial close contact, and there are gaps between the parts.

[0072] The second surface 140, the ninth surface 240 and the first surface 33 together form a working mating surface 90. The second surface 140 may be higher than the first surface 20 or lower than the first surface 33, that is, there is a height difference between the second surface 40 and the first surface 33, and the height difference is within a set range. The set range may be not greater than 2 mm, for example, 1 mm. Similarly, there may also be a height difference within the set range between the ninth surface 240 and the first surface 33.

[0073] As Figure 1 and Figure 3 As shown, in the first state, all structures of the pin 40 are covered by the first connecting member 100 and the second connecting member 200. The sixth surface 120 and the eighth surface 220 are fitted and in contact with each other. The third surface 110 is flush with the fourth surface 31. The seventh surface 210 and the fifth surface 32 are flush. The first left side surface 150 and the first side surface 35 are flush. The first right side surface 160 and the second side surface 36 are flush. The flushness between surfaces may be coplanar or there may be a slight height difference, which are all within the protection scope of the present application. When the sixth surface 120 and the eighth surface 220 are fitted, it includes the three situations of the above explanations of fitting, which will not be elaborated here. In the first state, the power adapter 10 appears as an integral cuboid structure with a good visual effect, and the pin 40 is completely covered and hidden. When the user puts the power adapter 10 into a pocket or a suitcase, the power adapter 10 will not damage the surrounding objects. In another embodiment, in the first state, part of the structure of the pin 40 is covered by the first connecting member 100 and the second connecting member 200, and part of the structure is exposed or protrudes from the first connecting member 100 and the second connecting member 200.

[0074] As Figure 2As shown, in one embodiment, the first connector 100 is provided with a first slot 121 that extends to the sixth surface 120. The shape of the first slot 121 is similar to the shape of the pin 40. The second connector 200 is provided with a second slot 221 that extends to the eighth surface 220. The shape of the second slot 221 is similar to the shape of the pin 40. In the first state, the first slot 121 and the second slot 221 are in communication, and the pin 40 can be received within the first slot 121 and the second slot 221. In one embodiment, in the length direction of the pin 40, i.e., the Y direction, the first slot 121 extends to the second surface 140 but there is a certain distance from the first top surface 130. The second slot 221 extends to the ninth surface 240 but there is a certain distance from the second top surface 230. Then, in the first state of the power adapter 10, the pin 40 is completely hidden and not exposed, and the appearance of the power adapter 10 presents a structure such as a cuboid or a cube, ensuring the overall appearance integrity of the power adapter 10. In another embodiment, as Figure 1 shown, in the length direction of the pin 40, i.e., the Y direction, the first slot 121 extends to the second surface 140 and the first top surface 130, and the second slot 221 extends to the ninth surface 240 and the second top surface 230. That is, the lengths of the first connector 100 and the second connector 200 protruding from the housing 30 are equal to the length of the pin 40. Then, in the first state of the power adapter 10, the pin 40 is flush with the first top surface 130 and the second top surface 230 respectively, so that the length dimension of the power adapter 10 is smaller, it is thinner and lighter, and is convenient to carry.

[0075] In one embodiment, the number of pins 40 is 2, and the number of the first slots 121 and the second slots 221 is both 2. In another embodiment, the number of pins 40 is 1, 3 or more, and the number of the first slots 121 and the second slots 221 corresponds to the number of pins 40. The shape of the pin 40 can be cylindrical or flat, and no specific limitation is made here.

[0076] In another embodiment, the first connector 100 is a boxed structure with a hollow opening, and the second connector 200 is a boxed structure with a hollow opening. In the first state, the first connector 100 and the second connector 200 form a closed internal space, and the pin 40 is received within the internal space formed by the first connector 100 and the second connector 200, and the number of pins 40 is not limited.

[0077] Figure 3 and Figure 7aAs shown, in one embodiment, compared with the first state of the power adapter 10, the first connector 100 and the second connector 200 are respectively rotated about 180° with the width direction of the power adapter 10 as the axis. That is, when the power adapter 10 is in the first state, the first connector 100 and the second connector 200 are rotated 180° relative to the housing 30, so that the third surface 110 is fixedly attached to the fourth surface 31, and the seventh surface 210 and the fifth surface 32 are fixedly attached. Then the power adapter 10 is in the second state.

[0078] As Figure 2 and Figure 7a As shown, in one embodiment, the number of pins 40 is two. The two pins 40 are arranged in the width direction of the power adapter 10, i.e., the X direction. The distances between the two pins 40 and the fourth surface 31 are both L1, and the distances between the two pins 40 and the fifth surface 32 are both L2. When the power adapter 10 is in the second state, the distances between the two pins 40 and the sixth surface 120 are both L3, and L3 is equal to the sum of the thickness of the first connector 100 and L1. The distances between the two pins 40 and the eighth surface 220 are both L4, and L4 is equal to the sum of the thickness of the second connector 200 and L2. In the second state, the distance between the pin 40 and the edge of the working mating surface 90 is the minimum value of L3 and L4.

[0079] It can be understood that when the number of connectors 20 is one, in the second state, the minimum value of the distance between the pin 40 and the surface of the housing 30 facing away from the connector 20 and the distance between the pin 40 and the surface of the connector 20 facing away from the housing 30 needs to be greater than a preset value. When the connector 20 includes the first connector 100 and the second connector 200, in the second state, when the distance between the pin 40 and the edge of the power adapter 10 in the X direction is greater than the distance between the pin 40 and the edge of the power adapter 10 in the Z direction, the minimum value of the distance between the pin 40 and the plane where the sixth surface 120 is located and the distance between the pin 40 and the plane where the eighth surface 220 is located needs to be greater than a preset value.

[0080] Safety specification requirements, i.e., in the safety regulations, it is stipulated that in the second state of the power adapter 10, the distance from the pin 40 to the edge of the working mating surface 90 is not less than a preset value. In some embodiments, the preset value can be 6.5 mm, or other data, which is specifically determined according to the usage of the power adapter 10. It can be understood that in the second state, in the thickness direction of the power adapter, i.e., the Z direction, the distance from the pin 40 to the edge of the working mating surface 90 is not less than the preset value; and in the width direction of the power adapter, i.e., the X direction, the distance from the pin 40 to the edge of the working mating surface 90 is not less than the preset value. In one embodiment, L1 is equal to L2, that is, the 2 pins 40 are symmetrically arranged on the first surface 33, L3 is equal to L4, then the minimum value of the distance from the pin 40 to the edge of the working mating surface 90 is L3 or L4, and L3 or L4 is not less than the preset value. L1 is less than the preset value, for example, 2.65 mm, and L3 is not less than the preset value, for example, 8.4 mm. In another embodiment, L1 is not equal to L2, that is, the 2 pins 40 are asymmetrically arranged on the first surface 33. For example, the 2 pins 40 are close to the fourth surface 31, then L1 is less than L2, then L3 is less than L4, and the minimum value of the distance from the pin 40 to the edge of the working mating surface 90 is L3, and L3 is not less than the preset value; again, for example, the 2 pins 40 are close to the fifth surface 32, then L1 is greater than L2, then L3 is greater than L4, and the minimum value of the distance from the pin 40 to the edge of 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 both L3 and L4 are not less than the preset value.

[0081] In one embodiment, in the second state, there is a height difference within a set range between the second surface 140 and the first surface 33, for example, not greater than 2 mm, for example, 1 mm. The second surface 140 can be higher than the first surface 33 or lower than the first surface 33. Then the minimum distance from any part of the pin 40 to the plane where the sixth surface 120 is located is not less than the preset value, that is, the same as the minimum distance without height difference, which 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 pin 40 and the eighth surface 120 is the same as above and needs to be greater than the preset value. In the second state, the first connector 100 is attached to the housing 30, and the attachment includes the three cases explained above, that is, completely tightly attached without gaps, having gaps within 2 mm or other size ranges, and partially tightly attached and partially having gaps. When there are the above gaps between the first connector 100 and the housing 30, the minimum distance from any part of the pin 40 to the plane where the sixth surface 120 is located needs to be greater than the preset value. The minimum distance between the pin 40 and the plane where the eighth surface 220 is located needs to be greater than the preset value.

[0082] In the first state of the power adapter 10, the thickness of the power adapter 10 is the sum of the dimension of the pin 40 in the Z direction and L1 and L2. Both L1 and L2 are less than a preset value. When L1 and L2 are small, the thickness of the power adapter 10 is small. The power adapter 10 with a smaller thickness has an aesthetic appearance, a sense of technology, and is convenient to carry. In the second state of the power adapter 10, it can meet the safety regulations requirements. That is, the power adapter 10 of the present application has a smaller thickness in the first state and is convenient to carry; in the second state, the fitting of the first connecting member 100 and the second connecting member 200 with the housing 30 increases the distance from the pin 40 to the edge of the working mating surface 90, so that the power adapter 10 can meet the safety regulations requirements, that is, the requirements of safety specifications.

[0083] As Figure 7b shown, in one embodiment, the first connecting member 100 and the second connecting member 200 and the housing 30 are an integrally formed structure. The specific preparation method can adopt injection molding or other molding methods. In another embodiment, only the first connecting member 100 may be included. The first connecting member 100 may be located on the fourth surface 31 of the housing 30 or on the fifth surface 32 of the housing 30, which is not limited herein.

[0084] As Figure 8As described, in another embodiment, two pins 40 are arranged in the thickness direction of the power adapter 10, i.e., the Z direction, such that one pin 40 is close to the fourth surface 31 and the other pin 40 is close to the fifth surface 32. In the second state, the distances of the two pins 40 from the edge of the first connector 100, i.e., the sixth surface 120, are different, and the distances of the two pins 40 from the fourth surface 31 are different; the distances of the two pins 40 from the edge of the second connector 200, i.e., the eighth surface 220, are different, and the distances of the two pins 40 from the fifth surface 32 are different. Define the minimum distance from the pin 40 to the fourth surface 31 as L5, then the distance between the pin 40 close to the fourth surface 31 and the fourth surface 31 is L5; define the minimum distance from the pin 40 to the sixth surface 120 in the second state as L7, then the distance between the pin 40 close to the fourth surface 31 and the sixth surface 120 is L7; define the minimum distance from the pin 40 to the fifth surface 32 as L6, then the distance between the pin 40 close to the fifth surface 32 and the fifth surface 32 is L6; define the minimum distance from the pin 40 to the eighth surface 220 in the second state as L8, then the distance between the pin 40 close to the fifth surface 32 and the eighth surface 220 is L8. In this embodiment, the distance from the pin 40 to the edge of the working mating surface 90 is not less than a preset value, i.e., both L7 and L8 are not less than the preset value; and in the width direction of the power adapter 10, i.e., the X direction, the distance from the pin 40 to the edge of the working mating surface 90 is not less than the preset value, i.e., the minimum distance from the pin 40 to the first side surface 35 is not less than the preset value, and the minimum distance to the second side surface 36 is not less than the preset value. L5 and L6 may be equal or unequal, but both L5 and L6 are less than the preset value; L7 and L8 may be equal or unequal, but both L7 and L8 are not less than the preset value. In one embodiment, the preset value is 6.5 mm.

[0085] In one embodiment, both the first connector 100 and the second connector 200 are connected to the housing 30 through a hinge assembly. It can be understood that the hinge assembly may be a part of the connector 20 or a part of the housing 30. For example, the hinge assembly connected between the first connector 100 and the housing 30 is a part of the first connector 100 or a part of the housing 30; the hinge assembly connected between the second connector 200 and the housing 30 is a part of the second connector 200 or a part of the housing 30. Of course, the hinge assembly may also be a structure independent of the connector 20 and the housing 30 and is fixed between the connector 20 and the housing 30 by mechanical means or bonding means.

[0086] Such as Figures 9 to 12As shown in the figure, the hinge assembly includes a first hinge assembly 50. The first hinge assembly 50 includes a rotating shaft seat 51, a first rotating shaft 52, and a second rotating shaft 53. The first connecting member 100 and the rotating shaft seat 51 are rotatably connected through the first rotating shaft 52, and the housing 30 and the rotating shaft seat 51 are rotatably connected through the second rotating shaft 53. The first rotating shaft 52 and the second rotating shaft 53 are parallel. Thus, the first connecting member 100 can achieve a larger angle of rotation, so that the first connecting member 100 and the second connecting member 200 can block the pins 40 in the second state and can not hinder the pins 40 from being plugged into an external power supply in the first state.

[0087] As Figures 9 to 12 shown, in an embodiment, the first hinge assembly 50 may further include: a first mounting seat 54 and a second mounting seat 55. The first mounting seat 54 is fixedly mounted on the first connecting member 100 and the second connecting member 200 respectively. The first rotating shaft 52 is rotatably connected to the first connecting member 100 and the second connecting member 200 through the first mounting seat 54. The second mounting seat 55 is fixedly mounted on the housing 30. The second rotating shaft 53 is rotatably connected to the housing 30 through the second mounting seat 55. That is to say, the first mounting seat 54 is fixedly connected to the first connecting member 100 and rotates synchronously. Thus, when the first rotating shaft 52 penetrates through the first mounting seat 54 and the rotating shaft seat 51, the first mounting seat 54 is rotatable relative to the rotating shaft seat 51, so that the first connecting member 100 is rotatable relative to the rotating shaft seat 51. The second mounting seat 55 is fixedly connected to the housing 30 and rotates synchronously. Thus, when the second rotating shaft 53 penetrates through the second mounting seat 55 and the rotating shaft seat 51, the second mounting seat 55 is rotatable relative to the rotating shaft seat 51, so that the housing 30 is rotatable relative to the rotating shaft seat 51.

[0088] Thus, the assembly of the first hinge assembly 50 with the housing 30, the first connecting member 100, and the second connecting member 200 can be simply and effectively realized. Moreover, by providing the first mounting seat 54, the connection between the first hinge assembly 50 and the first connecting member 100 and the second connecting member 200 can be made stable and firm, and the risk that the first hinge assembly 50 is disconnected from the first connecting member 100 and the second connecting member 200 during long-term use can be reduced. By providing the second mounting seat 55, the connection between the first hinge assembly 50 and the housing 30 can be made stable and firm, and the risk that the first hinge assembly 50 is disconnected from the housing 30 during long-term use can be reduced.

[0089] As Figures 9 to 12As shown, in one embodiment, the first mounting seat 54 wraps around the opposite sides of the rotating shaft seat 51, and the second mounting seat 55 wraps around the opposite sides of the rotating shaft seat 51, and the first mounting seat 54 and the second mounting seat 55 are butted. That is, the first mounting seat 54 and the second mounting seat 55 are butted to form an internal space, and the rotating shaft seat 51 is located in this internal space. The first rotating shaft 52 passes through the rotating shaft seat 51 and the first mounting seat 54, so that the first mounting seat 54 can rotate relative to the rotating shaft seat 51 around the first rotating shaft 52. The second rotating shaft 53 passes through the rotating shaft seat 51 and the second mounting seat 55, so that the second mounting seat 55 can rotate relative to the rotating shaft seat 51 around the second rotating shaft 53. A first arc surface 541 is provided at a position where the first mounting seat 54 is close to the second mounting seat 55, and a second arc surface 551 is provided at a position where the second mounting seat 55 is close to the first mounting seat 54. When the first mounting seat 54 or the second mounting seat 55 rotates relative to the rotating shaft seat 51, the first arc surface 541 and the second arc surface 551 provide an avoidance space, so that the first mounting seat 54 and the second mounting seat 55 can rotate relative to the rotating shaft seat 51.

[0090] First accommodating grooves 141 are formed on the first connecting member 100 and the second connecting member 200, and a second accommodating groove 331 is formed on the housing 30. The first mounting seat 54 is fixed in the first accommodating groove 141, and the second mounting seat 55 is fixed in the second accommodating groove 331, so that the first connecting member 100 and the second connecting member 200 are respectively connected to the housing 30 through the first hinge assembly 50. Specifically, the first mounting seat 54 and the second mounting seat 55 can be respectively bonded and fixed in the first accommodating groove 141 and the second accommodating groove 331; or the first mounting seat 54 and the second mounting seat 55 are respectively fixed in the first accommodating groove 141 and the second accommodating groove 331 by mechanical fixing means.

[0091] In Figure 13 In the specific example shown, the first connecting member 100 and the second connecting member 200 are in the first state. At this time, the first connecting member 100 and the second connecting member 200 are located directly above the housing 30, and the first rotating shaft 52 is located directly above the second rotating shaft 53. By separating the first connecting member 100 and the second connecting member 200 in a direction away from each other, that is, flipping the first connecting member 100 to the left and flipping the second connecting member 200 to the right. At this time, the first mounting seat 54 and the rotating shaft seat 51 can rotate relative to the housing 30 synchronously around the second rotating shaft 53. Combining Figure 14 , is the state where the first mounting seat 54 and the rotating shaft seat 51 rotate 90° relative to the housing 30 synchronously around the second rotating shaft 53. At this time, the first connecting member 100 and the second connecting member 200 are in a transition state between the first state and the second state. After that, the housing 30 and the rotating shaft seat 51 are relatively stationary, and the first mounting seat 54 rotates relative to the housing 30 and the rotating shaft seat 51 around the first rotating shaft 52. Combining Figure 15, is a state where the first mounting base 54 rotates 90° relative to the housing 30 and the rotating shaft base 51 around the first rotating shaft 52. At this time, the first connecting member 100 and the second connecting member 200 are in the second state, and the first rotating shaft 52 and the second rotating shaft 53 are at the same horizontal height.

[0092] It should be noted that the above principle of the action process is not the only action state of the first hinge assembly 50, but an idealized working state described for the sake of clear introduction. In fact, during the action of the first hinge assembly 50, it is very likely that while the first mounting base 54 rotates around the first rotating shaft 52 relative to the rotating shaft base 51, the rotating shaft base 51 also moves relative to the housing 30 around the second rotating shaft 53, so as to realize the switching from the first state to the second state. Similarly, according to the reverse action, the action process of the first connecting member 100 and the second connecting member 200 rotating back from the second state to the first state can be known, which will not be elaborated here. In addition, in order to avoid interference between the rotating shaft base 51 and the housing 30 and ensure that in the second state, the third surface 110 and the seventh surface 210 can be respectively attached to the fourth surface 31 and the fifth surface 32, an avoidance notch 511 can be provided on the rotating shaft base 51.

[0093] As Figure 16 and Figure 17 shown, in an embodiment, the hinge assembly includes a second hinge assembly 60. The second hinge assembly 60 includes a rotating shaft base 51, a first rotating shaft 52 and a second rotating shaft 53. The first connecting member 100 and the rotating shaft base 51 are rotatably connected through the first rotating shaft 52, the housing 30 and the rotating shaft base 51 are rotatably connected through the second rotating shaft 53, and the first rotating shaft 52 and the second rotating shaft 53 are parallel. Specifically, the first rotating shaft 52 is fixed to one of the first connecting member 100 and the rotating shaft base 51, and at least part of the structure of the first rotating shaft 52 penetrates through the other of the first connecting member 100 and the rotating shaft base 51. The second rotating shaft 53 is fixed to one of the housing 30 and the rotating shaft base 51, and at least part of the structure of the second rotating shaft 53 penetrates through the other of the housing 30 and the rotating shaft base 51. The connection mode of the second connecting member 200 and the housing 30 is the same as that of the first connecting member 100. So that the first connecting member 100 and the second connecting member 200 can rotate relative to the housing 30 and can be in the first state and the second state.

[0094] As Figure 18 shown, in an embodiment, the hinge assembly includes a third hinge assembly 70. The first connecting member 100 and the second connecting member 200 can rotate through the third hinge assembly 70 to be in the first state and the second state, and can be respectively fixed in the first state and the second state. It should be noted that the "fixing" mentioned in this paragraph does not mean permanent fixing, but means that the first connecting member 100 and the second connecting member 200 can be kept in the corresponding state without external force.

[0095] As shown Figure 18 in FIG. a, the third hinge assembly 70 may include: a first rotating member 71, a second rotating member 72, a torsion spring 75, a first pivot 73, and a second pivot 74. As shown Figure 18 in FIG. b, the first rotating member 71 or the second rotating member 72 presents a first state and is in a first stable position. As shown Figure 18 in FIG. d, the first rotating member 71 or the second rotating member 72 presents a second state and is in a second stable position. It can be understood that one end of the first rotating member 71 fixed to the first connecting member 100 or the second connecting member 200 can be bent according to actual needs, or two bends can be provided according to needs, so that in the first state, the first connecting member 100 and the second connecting member 200 can fit together, and in the second state, the first connecting member 100 and the second connecting member 200 can respectively fit to the housing 30.

[0096] As shown Figure 18 in FIG. a, the first rotating member 71 is rotatably connected to the housing 30 through the first pivot 73, and the second rotating member 72 is rotatably connected to the housing 30 through the second pivot 74. Wherein, one end of the first rotating member 71 is fixed to the first connecting member 100 or the second connecting member 200, and the other end abuts against the second rotating member 72. One end of the second rotating member 72 is provided with the second pivot 74, and the other end is a free end. The torsion spring 75 is sleeved on the second pivot 74, and one end is fixed to the housing 30 and the other end is fixed to the second rotating member 72, so that the end of the second rotating member 72 far from the second pivot 74 has a tendency to rotate towards the first rotating member 71. As shown Figure 18 in FIG. b, in the first state, one side of the first rotating member 71 abuts against the second rotating member 72, and the torsion spring 75 is in a compressed state, so that the end of the second rotating member 72 far from the second pivot 74 has a tendency to rotate towards the first rotating member 71; or the torsion spring 75 is in a natural state, but when the first rotating member 71 rotates, the second rotating member 72 needs to rotate and compress the torsion spring 75 to make room for the first rotating member 71, so when no force is applied to the first rotating member 71, the first rotating member 71 and the second rotating member 72 can also be fixed.

[0097] As shown Figure 18 in FIG. c, when a force is applied to the first rotating member 71, the first rotating member 71 can rotate, and the second rotating member 72 can rotate under the action of the first rotating member 71 until it reaches the second state as shown Figure 18 in FIG. d. In the second state, the other side of the first rotating member 71 abuts against the second rotating member 72, and the torsion spring 75 is in a compressed state, so that the end of the second rotating member 72 far from the second pivot 74 has a tendency to rotate towards the first rotating member 71, and the first rotating member 71 and the second rotating member 72 can be fixed.

[0098] It is understandable that the position and number of hinge assemblies can be specifically set and selected according to actual requirements. The first connector 100 and the housing 30 can be connected by one hinge assembly, and the hinge assembly is located at the center or close to the center of the width direction of the power adapter 10, i.e., the X direction. The first connector 100 and the housing 30 can be connected by two hinge assemblies, and the two hinge assemblies are respectively located at the two ends of the width direction of the power adapter 10, i.e., the X direction, or close to the two ends. The second connector 200 can also be connected to the housing 30 by one hinge assembly or two hinge assemblies, and the position of the hinge assembly can be the same as or different from the position of the hinge assembly connected between the first connector 100 and the housing 30.

[0099] like Figure 2 and Figure 5 As shown, in one embodiment, a fifth magnetic body 125 is provided in the first connecting member 100, and a sixth magnetic body 225 is provided in the second connecting member 200. In the first state, the first connecting member 100 and the second connecting member 200 are magnetically attracted and attached to each other by the magnetic force of the fifth magnetic body 125 and the sixth magnetic body 225. In the second state, the first connecting member 100 and the second connecting member 200 are magnetically attracted and attached to opposite sides of the housing 30 by the magnetic force of the fifth magnetic body 125 and the sixth magnetic body 225.

[0100] like Figure 2 and Figure 5 As shown, in one embodiment, the first connecting member 100 is provided with a first groove 122, and the first groove 122 extends to the sixth surface 120. A fifth magnetic body 125 is provided in the first groove 122. The second connecting member 200 is provided with a second groove 222, and the second groove 222 extends to the eighth surface 220. A sixth magnetic body 225 is provided in the second groove 222. 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 connecting member 100 and the second connecting member 200. 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 two can be magnetically attracted by a magnet, such as an ordinary iron block.

[0101] In another embodiment, the fifth magnetic body 125 can be located on the third surface 110 of the first connecting member 100 or covered inside the first connecting member 100, and the sixth magnetic body 225 can be located on the seventh surface 210 of the second connecting member 200 or covered inside the second connecting member 200, which can also enable the existence of a mutual magnetic force of attraction between the first connecting member 100 and the second connecting member 200.

[0102] like Figure 3As shown, in the first state of the power adapter 10, the first connector 100 and the second connector 200 are magnetically fixed to each other by the fifth magnet 125 and the sixth magnet 225, and the magnetic forces of the fifth magnet 125 and the sixth magnet 225 pass through the sixth surface 120 and the eighth surface 220. When the user places it in a pocket or a suitcase, the first connector 100 and the second connector 200 hide the pins 40, preventing the pins 40 from scratching surrounding objects, and the first connector 100 and the second connector 200 are not easily opened, enabling the power adapter 10 to reliably hide the pins 40 during storage or transportation.

[0103] As Figure 3 , Figure 6 and Figure 7a As shown, in one embodiment, the magnetic force of mutual attraction between the fifth magnet 125 and the sixth magnet 225 includes a first magnetic force F1 and a second magnetic force F2. The first magnetic force F1 passes through the sixth surface 120 and the eighth surface 220, causing the first connector 100 and the second connector 200 to tend to rotate to the first state; the second magnetic force F2 passes through the third surface 110, the seventh surface 210, and the housing 30, causing the first connector 100 and the second connector 200 to tend to rotate to the second state.

[0104] When the power adapter 10 is in the first state, the first connecting member 100 and the second connecting member 200 are attracted and tightened by the first magnetic force F1 between the fifth magnetic body 125 and the sixth magnetic body 225 and do not open. When it is necessary to open the first connecting member 100 and the second connecting member 200, the user needs to apply a force to the first connecting member 100 or the second connecting member 200 to overcome the first magnetic force F1 between the fifth magnetic body 125 and the sixth magnetic body 225, so that the first connecting member 100 or the second connecting member 200 can rotate relative to the housing 30. There is a critical angle α, which is the angle between the first connecting member 100 or the second connecting member 200 and the housing 30, that is, the included angle between the plane where the third surface 110 and the fourth surface 31 are located, or the included angle between the plane where the seventh surface 210 and the fifth surface 32 are located. When one of the first connecting member 100 and the second connecting member 200 is in the first state or the second state, and the angle between the other of the first connecting member 100 and the second connecting member 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 to make the first connecting member 100 and the second connecting member 200 in a balanced state. When one of the first connecting member 100 and the second connecting member 200 is in the second state, and the angle between the other of the first connecting member 100 and the second connecting member 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 connecting member 100 and the second connecting member 200 can automatically return to the first state. When one of the first connecting member 100 and the second connecting member 200 is in the first state, and the angle between the other of the first connecting member 100 and the second connecting member 200 and the housing 30 is less than the critical angle α, the first magnetic force F1 is less than the second magnetic force F2, and the first connecting member 100 and the second connecting member 200 can automatically return to the second state.

[0105] Assume that the user applies a force to the first connecting member 100, and the first connecting member 100 rotates while the second connecting member 200 remains stationary. At this time, the first magnetic force F1 is greater than the second magnetic force F2, causing the first connecting member 100 and the second connecting member 200 to tend to return to the first state. When rotating the first connecting member 100 from the first state and before reaching the state where the included angle between the first connecting member 100 and the housing 30 is the critical angle α, the first magnetic force F1 gradually weakens, the second magnetic force F2 gradually strengthens, and the first magnetic force F1 is greater than the second magnetic force F2, causing the first connecting member 100 and the second connecting member 200 to tend to return to the first state. When the first connecting member 100 rotates to the included angle with the housing 30 being the critical angle α, the first magnetic force F1 and the second magnetic force F2 are in an equilibrium state, enabling the first connecting member 100 and the second connecting member 200 to be in an equilibrium state. Ideally, the first connecting member 100 and the second connecting member 200 can remain stationary in this state. As the user continues to apply force, the first magnetic force F1 continues to decrease, the second magnetic force F2 continues to strengthen, but the first magnetic force F1 is always less than the second magnetic force F2. Then the user can stop applying force to the first connecting member 100, and the second magnetic force F2 causes the first connecting member 100 and the second connecting member 200 to automatically rotate relative to the housing 30 until both the first connecting member 100 and the second connecting member 200 are in contact with the housing 30. When the power adapter 10 is in the second state and the user uses the power adapter 10 to supply power to electronic components, the first connecting member 100 and the second connecting member 200 are fixedly attached to the housing 30 and will not shake or rotate, which is convenient for use. It can be understood that when the power adapter 10 needs to be opened, the user can also choose to apply a force to the second connecting member 200, and the power adapter 10 can also be opened in the same way as when the user applies a force to the first connecting member 100, and the working principle is the same.

[0106] Such as Figure 3 , Figure 6 and Figure 7aAs shown, in one embodiment, in the second state of the power adapter 10, the first connector 100 and the second connector 200 are attracted and tightened by the second magnetic force F2 between the fifth magnet 125 and the sixth magnet 225 and do not open. When the power adapter 10 needs to be closed, the user needs to apply a force to the first connector 100 or the second connector 200 to overcome the second magnetic force F2 between the fifth magnet 125 and the sixth magnet 225, so that the first connector 100 or the second connector 200 can rotate relative to the housing 30. Assuming that the user applies a force to the first connector 100, the first connector 100 leaves the housing 30 and rotates, and the second connector 200 remains in contact with the housing 30. As the first connector 100 rotates, the second magnetic force F2 weakens and the first magnetic force F1 gradually increases, but the second magnetic force F2 is always greater than the first magnetic force F1. When the angle between the first connector 100 and the housing 30 reaches the critical angle α, the first magnetic force F1 and the second magnetic force F2 are in an equilibrium state, that is, the first connector 100 and the second connector 200 are in an equilibrium state under the combined action of the first magnetic force F1 and the second magnetic force F2. Ideally, the first connector 100 and the second connector 200 can be in a stationary state. As the user continues to apply a force to the first connector 100, the balance state between the first magnetic force F1 and the second magnetic force F2 is broken, so that the first magnetic force F1 is greater than the second magnetic force F2, and the user can stop applying a force to the first connector 100. The first magnetic force F1 can cause the first connector 100 and the second connector 200 to automatically rotate relative to the housing 30 until the first connector 100 and the second connector 200 are in contact and fixed, so that the power adapter 10 is in the first state. In the first state of the power adapter 10, during storage, transportation, daily placement, or movement, the first connector 100 and the second connector 200 are tightly fixed, having the reliability of hiding the plug 40, and are relatively thin, which is convenient for carrying. It can be understood that when the power adapter 10 needs to be closed, the user can also choose to apply a force to the second connector 200, and the power adapter 10 can also be closed, and the working principle is the same as the way of applying a force to the first connector 100 by the user.

[0107] In one embodiment, part or all of the structure of the first connector 100 is made of a magnetic material, and part or all of the structure of the second connector 200 is made of a magnetic material, so that there is a mutually attractive magnetic force between the first connector 100 and the second connector 200. Thus, the automatic opening and automatic closing between the first connector 100 and the second connector 200 can be realized, and the implementation principle is the same as above and will not be elaborated here.

[0108] In one embodiment, part or all of the structure of the connecting member 20 is made of a magnetic material, and part or all of the structure of the housing 30 is made of a magnetic material, so that there is an attractive magnetic force between the connecting member 20 and the main body. For example, part of the structure of the first connecting member 100 and the second connecting member 200 is made of a magnetic material, 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 connecting member 100 and the housing 30, and there is an attractive magnetic force between the second connecting member 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 connecting member 100 and the second connecting member 200 can also be realized, and the implementation principle is the same as above, so it will not be elaborated here.

[0109] In one embodiment, when the power adapter 10 is in the first state, the first connecting member 100 and the second connecting member 200 are fixed by a buckle. In the second state, the first connecting member 100 and the second connecting member 200 are respectively fixedly connected to the housing 30 by a buckle. It can be understood that the present application is not limited to the buckle fixing method, and other fixing methods that can be realized are also within the protection scope of the present application. In another embodiment, the buckle fixing method can be used in combination with the magnetic attraction method. For example, in the first state, the first connecting member 100 and the second connecting member 200 are fixed by the magnetic attraction method, and in the second state, the first connecting member 100 and the second connecting member 200 are respectively fixed to the housing 30 by the buckle method. In yet another embodiment, the buckle fixing method can be used in combination with the magnetic attraction method, and no further examples will be given here.

[0110] In one embodiment, a method for manufacturing a power adapter 10 is provided, including the following steps:

[0111] Provide a pin 40, a first housing 300, a second housing 400, a hinge assembly, a first connecting member 100 and a second connecting member 200, and there is a magnetic force between the first connecting member 100 and the second connecting member 200;

[0112] Fix the pin 40 to the first housing 300;

[0113] Fix the first housing 300 and the second housing 400 to form the housing 30; and

[0114] Rotatably connect the first connecting member 100 and the second connecting member 200 to opposite sides of the housing 30 respectively;

[0115] Wherein, the first connecting member 100 and the second connecting member 200 have a first state and a second state relative to the housing 30. In the first state, the first connecting member 100 and the second connecting member 200 are attached and fixed, and at least part of the structure of the pin 40 is covered by the first connecting member 100 and the second connecting member 200; in the second state, the first connecting member 100 and the second connecting member 200 are respectively attached and fixed to both sides of the housing 30.

[0116] As Figure 19 and Figure 20 shown, in one embodiment, the pin 40 is fixed to the first housing 300 together, or directly purchase the pin 40 and the first housing 300 that are fixed as a whole. The pin 40 and the first housing 300 can be formed into an integral structure by in-mold injection. Then, the first housing 300 and the second housing 400 are fixed by ultrasonic heat melting or other processes to form the housing 30. It can be understood that the first housing 300 is provided with 4 second receiving grooves 331. In other embodiments, the number and position of the second receiving grooves 331 are changed according to actual needs.

[0117] As Figure 21 and Figure 22 shown, in one embodiment, four hinge assemblies are respectively fixed in the 4 second receiving grooves 331. The second mounting seat 55 is fixed in the second receiving groove 331, and the first mounting seat 54 is located outside the second receiving groove 331. The second mounting seat 55 can be bonded in the second receiving groove 331 by means of dispensing, or can be fixed in the second receiving groove 331 by means of mechanical fixing.

[0118] As Figure 23 and Figure 24 shown, in one embodiment, the fifth magnetic body 125 and the sixth magnetic body 225 are respectively installed in the first connecting member 100 and the second connecting member 200, so that there is a magnetic force of mutual attraction between the first connecting member 100 and the second connecting member 200.

[0119] As Figure 25 and Figure 26 shown, in one embodiment, the first connecting member 100 and the second connecting member 200 are respectively installed on the housing 30. Specifically, the first mounting seat 54 is respectively fixed in the first receiving groove 141 of the first connecting member 100 and the second connecting member 200, so that the first connecting member 100 and the second connecting member 200 are respectively rotatably connected to the housing 30 through hinge assemblies.

[0120] As Figure 2 、 Figure 6 and Figure 7aAs shown, in one embodiment, the fifth magnetic body 125 is fixed in the first groove 122, and the sixth magnetic body 225 is fixed in the second groove 222. When the power adapter 10 is in the first state, based on the principle of the magnetic fields of the fifth magnetic body 125 and the sixth magnetic body 225, when the first connector 100 or the second connector 200 is opened to the critical angle α, 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, thereby realizing the automatic opening of the first connector 100 and the second connector 200 and being able to maintain the open state all the time. Similarly, when the power adapter 10 is in the second state, when the first connector 100 or the second connector 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 less than the first magnetic force F1, and the first connector 100 and the second connector 200 will also automatically close and rely on the magnetic force to maintain the first state.

[0121] The power adapter 10 has a relatively thin thickness. Since the pins 40 do not need to occupy the space inside the housing 30, the size of the housing 30 can be reduced, thereby reducing the overall volume of the power adapter 10, and it has good portability. In the non-use state, the power adapter 10 can be placed in the first state, and the pins 40 are hidden, which has portability and the pins 40 will not damage surrounding objects. When the power adapter 10 is in the second state, the first connector 100 and the second connector 200 are attached to the housing 30, so that the power adapter 10 meets the safety regulations requirements. Utilizing the magnetic field characteristics of the fifth magnetic body 125 and the sixth magnetic body 225, after the first connector 100 or the second connector 200 is opened or closed to the critical angle α, the first connector 100 and the second connector 200 can together realize the function of automatic opening or closing, improving the user experience.

[0122] As Figures 27 to 29 shown, in one embodiment, the number of the connectors 20 is 1. When in the second state, the distance between the pins 40 and the surface of the side of the connector 20 facing away from the housing 30 is not less than a preset value, and the distance between the pins 40 and the surface of the side of the housing 30 facing away from the connector 20 is not less than a preset value. This enables the power adapter 10 to be made relatively thin and can be used normally in the second state.

[0123] As Figures 27 to 29As shown, in one embodiment, the number of the connecting members 20 is 1, the number of the pins 40 is 2, and the two pins 40 are arranged in the width direction of the housing 30, i.e., the X direction. The connecting member 20 is rotatably connected to the housing 30 through a hinge assembly. The connecting member 20 can rotate relative to the housing 30 and has a first state and a second state. In the first state, the connecting member 20 covers the end of the housing 30, and at least part of the structure of the pin 40 can be received in the connecting member 20. The entire structure of the pin 40 can be received in the connecting member 20, or part of the structure can be exposed. In the second state, the connecting member 20 is opened and stacked on one side of the body, and the surfaces of the body of the connecting member 20 are in contact. The contact can be understood as there being no gap between the two, or there can be a slight gap. The distance from the pin 40 to the surface of the side of the connecting member 20 facing away from the housing 30 is not less than a preset value, and the distance from the pin 40 to the surface of the side of the housing 30 facing away from the connecting member 20 is not less than a preset value, so that the power adapter 10 meets the requirements of safety specifications. In one embodiment, the preset value is 6.5 mm. In other embodiments, the preset value can also be other values, such as 5.1 mm, 7.9 mm.

[0124] Define the distance from the pin 40 to the edge of the working mating surface 90 as the minimum distance between any point of the pin 40 and the edge of the working mating surface 90 along the length direction of the pin 40, i.e., the plane in the Y direction. When the number of the connecting members 20 is 1, in the second state, when there is a height difference between the connecting member 20 and the first surface 33, such as not greater than 2 mm, the distance from the pin 40 to the edge of the working mating surface 90 is the same as when there is no height difference; in the second state, when there is a gap between the connecting member 20 and the housing 30, such as not greater than 2 mm, the distance from the pin 40 to the edge of the working mating surface 90 is the same as above, which is the minimum distance between any point of the pin 40 and the edge of the working mating surface 90 along the plane in the Y direction.

[0125] As Figure 27 shown, in the first state, the connecting member 20 is in contact with the first surface 33, and the connecting member 20 extends along the length direction of the housing 30, i.e., the Y direction. After being flipped, the connecting member 20 can rotate to the second state. As Figure 29 shown, in the second state, the connecting member 20 is in contact with the fifth surface 32, and the second surface 140 of the connecting member 20 connected to the housing 30 is flush with the first surface 33 of the housing 30 and forms a working mating surface 90.

[0126] In one embodiment, at least part of the structure of the connecting member 20 or the housing 30 is made of a magnetic material, so that there is a magnetic force of mutual attraction between the connecting member 20 and the housing 30.

[0127] In one embodiment, in the first state, the connecting member 20 and the first surface 30 are fixed by a snap; in the second state, the connecting member 20 and the fourth surface 31 or the fifth surface 32 are fixed by a snap. It can be understood that in the first state and the second state, the connecting member 20 and the housing 30 can also be fixed by other means, that is, other fixing means are also within the protection scope of the present application, as long as the connecting member 20 and the housing 30 can be fixed in the first state or the second state.

[0128] As Figures 27 to 29 shown, in one embodiment, a first magnetic body 123 and a third magnetic body 124 are provided inside the connecting member 20, and a second magnetic body 223 and a fourth magnetic body 224 are provided inside the housing 30. The first magnetic body 123 is close to the second surface 140, the second magnetic body 223 is close to the adjacent surface of the second surface 140, the third magnetic body 124 is close to the first surface 33, and the fourth magnetic body 224 is close to the fifth surface 32. In the first state, the connecting member 20 and the housing 30 are magnetically fixed by the magnetic force of mutual attraction between the first magnetic body 123 and the second magnetic body 223. In the second state, the connecting member 20 and the housing 30 are magnetically fixed by the magnetic force of mutual attraction between the third magnetic body 124 and the fourth magnetic body 224. During the rotation of the connecting member 20, when the magnetic force between the first magnetic body 123 and the second magnetic body 223 is greater than the magnetic force between the third magnetic body 124 and the fourth magnetic body 224, the connecting member 20 can automatically rotate to the first state and can maintain the first state. When the magnetic force between the first magnetic body 123 and the second magnetic body 223 is less than the magnetic force between the third magnetic body 124 and the fourth magnetic body 224, the connecting member 20 can automatically rotate to the second state and can maintain the second state.

[0129] In one embodiment, the snap fixing method can be combined with the magnetic fixing method. For example, in the first state, the connecting member 20 and the housing 30 can be magnetically fixed by the first magnetic body 123 and the second magnetic body 223. In the second state, the connecting member 20 and the housing 30 can be fixed by a snap. Or, in the first state, the connecting member 20 and the housing 30 can be fixed by a snap. In the second state, the connecting member 20 and the housing 30 can be magnetically fixed by the third magnetic body 124 and the fourth magnetic body 224. Or, in the first state, the connection 20 and the housing 30 are fixed by both a snap and magnetically fixed by the first magnetic body 123 and the second magnetic body 223; in the second state, the connection 20 and the housing 30 are fixed by both a snap and magnetically fixed by the third magnetic body 124 and the fourth magnetic body 224.

[0130] As Figure 30As shown, in one embodiment, two pins 40 are arranged in the thickness direction of the power adapter 10, i.e., the Z direction, that is, one pin 40 is close to the fourth surface 31, and the other pin 40 is close to the fifth surface 32. The distances of the two pins 40 from the fourth surface 31 are different, and the distances of the two pins 40 from the fifth surface 32 are different. In the second state, the distances of the two pins 40 from the edge of the connecting member 20 are different. In this embodiment, in the second state, the distance of the pin 40 from the edge of the working mating surface 90 is not less than a preset value, that is, the distance between the pin 40 close to the fourth surface 31 and the fourth surface 31 is not less than the preset value, and the distance between the pin 40 far from the fourth surface 31 and the side of the connecting member 20 away from the housing 30 is not less than the preset value. The distances between the two pins 40 and the first side surface 35 are not less than the preset value, and the distances between the two pins 40 and the second side surface 36 are not less than the preset value. In one embodiment, the preset value is 6.5 mm.

[0131] As Figure 31 shown, in one embodiment, the pin 40 is arranged along the width direction of the housing 30, i.e., the X direction, then the connecting member 20 is rotatably connected to the first side surface 35 or the second side surface 36 of the housing 30. In the second state, the connecting member 20 is attached to the fourth surface 31 or the fifth surface 32 of the housing 30. It can also achieve that the power adapter 10 is thinner in the first state and can meet the safety requirements in the second state.

[0132] As Figure 32 shown, in one embodiment, the connecting member 20 can be inserted and removed in cooperation with the housing 30 to have a first state and a second state. For example, in the first state, at least part of the structure of the pin 40 is received in the connecting member 20. The connecting member 20 can be first pulled out in the direction shown by the arrow S1, then flipped in the direction shown by the arrow S2, and then arranged on one side of the thickness of the housing 30 in the direction shown by the arrow S3, so that the connecting member 20 is in the second state, and the second surface 140 is flush with the first surface 33 to meet the safety requirements. It can be understood that in the second state, the connecting member 20 can be magnetically fixed to the housing 30 or fixed by means of a buckle or the like. This embodiment can also achieve that the power adapter 10 is thinner in the first state and can meet the safety requirements in the second state.

[0133] Another example is in Figure 33In the illustrated example, the connecting member 20 can be slidably mated with the housing 30 and includes a first mating member and a second mating member. The first mating member and the second mating member can be first slid out separately in the direction indicated by the arrow S4, and then mated in the direction indicated by the arrow S5 to form the connecting member 20 (for example, they can be mated and fixed by means of snap or magnetic attraction), and a second surface 140 is formed. Then, the mated connecting member 20 is disposed on one side of the thickness of the housing 30 in the direction indicated by the arrow S6, so that the second surface 140 is flush with the first surface 33 to form a working mating surface 90.
