Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

Reference herein to "an embodiment" or "an implementation" means that a particular feature, structure, or characteristic described in connection with the embodiment or implementation can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The present application provides a Power adapter 10. Referring to fig. 1, fig. 1 is a schematic application environment diagram of a power adapter according to an embodiment of the present disclosure. The power adapter 10 is a conversion device that supplies power to the electronic device 30. Generally, the power adapter 10 may convert an alternating voltage to a direct voltage. For example, the power adapter 10 is plugged into the socket 50, receives the ac voltage output by the socket 50, and converts the received ac voltage into a dc voltage, which is used to charge the electronic device 30 using electricity, such as a mobile phone and a computer. It is to be appreciated that in other embodiments, the power adapter 10 converts the received ac voltage to a dc voltage that is directly available to the electronic components in the electronic device 30. It is to be understood that the schematic diagram of the application environment of the power adapter 10 is only helpful for understanding the application of the power adapter 10, and should not be construed as limiting the power adapter 10 provided in the present application.

Referring to fig. 2, fig. 3 and fig. 4 together, fig. 2 is a schematic view illustrating a cover in a power adapter according to an embodiment of the present disclosure in a closed state; fig. 3 is a schematic view of the power adapter shown in fig. 2 with a cover in an open state; FIG. 4 is a schematic view of another angle of the power adapter shown in FIG. 3. The power adapter 10 includes an adapter body 100, pins 200, and a cover 300. The adapter body 100 has a first end face 161. The pins 200 are exposed at the first end surface 161 of the adapter body 100. The cover 300 is movably connected to the adapter body 100, and the cover 300 has a second end surface 340. When the cover 300 is in the closed state, the pins 200 are covered, and the second end surface 340 faces away from the adapter body 100; when the cover 300 is in the open state, the first end surface 161 and the second end surface 340 together form the plugging surface 11 of the power adapter 10.

It should be noted that the terms "first", "second", and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.

The adapter body 100 is a part that realizes the voltage conversion function of the power adapter 10. The adapter body 100 generally includes a circuit board for voltage conversion, and the adapter body 100 may further include a housing or the like for accommodating the circuit board. The specific structure included in the adapter body 100 will be described in detail later in conjunction with the exploded view of the power adapter 10.

The plug pins 200 are made of metal, and the plug pins 200 are inserted into the socket 50 and used for receiving an alternating voltage provided by the socket 50. The number of the pins 200 may be, but not limited to, two, and in the present embodiment, the number of the pins 200 is two. The two pins 200 are opposed and spaced apart. The pins 200 may be, but are not limited to, elongated. The end of the pin 200 facing away from the body of the socket 50 is curved to facilitate insertion of the pin 200 into the socket 50. When the pin 200 is inserted into the socket 50 to receive a first voltage, the circuit board 120 is electrically connected to the pin 200 to receive the first voltage transmitted from the pin 200, and the circuit board is used to convert the first voltage into a second voltage.

When the cover 300 is in the closed state, the pins 200 are covered, including but not limited to the following cases: the pins 200 are covered by the cover 300; alternatively, the pins 200 are covered by the adapter body 100; alternatively, the pins 200 are covered by both the adapter body 100 and the cover 300. The case where the pins 200 are covered by the cover 300 is exemplified by the case where the cover 300 has receiving cavities in which the pins 200 are received when the cover 300 is closed, so as to cover the pins 200. The case where the pins 200 are covered by the adapter body 100 is exemplified by the case where the adapter body 100 has a receiving cavity, and when the cover 300 is closed, the pins 200 are received back in the receiving cavity, and in this case, the pins 200 are covered by the adapter body 100. The plug pins 200 are covered by the adapter body 100 and the cover 300, for example, the adapter body 100 and the cover 300 together form a receiving cavity, and when the cover 300 is closed, the plug pins 200 are received in the receiving cavity formed by the adapter body 100 and the cover 300 together.

In the present embodiment, an example that the cover 300 is movably connected to the adapter body 100 is that the cover 300 can slide relative to the adapter body 100 is described, specifically, the cover 300 includes a first cover 310 and a second cover 320, and the first cover 310 and the second cover 320 are respectively connected to the adapter body 100 and can slide compared to the adapter body 100 is described as an example. It is understood that in other embodiments, the manner of connecting the cover 300 to the adapter body 100 may be other manners, for example, the cover is turned over several times and then the position of the cover is adjusted. As long as it is satisfied that the second end surface 340 and the first end surface 161 together form the plugging surface 11 of the power adapter 10.

In the schematic view of the present embodiment, the plug 200 is fixed to the adaptor body 100 and exposed from the first inserting surface 11. The number of the cover 300 is two for illustration, that is, the cover 300 includes a first cover 310 and a second cover 320. It is understood that in other embodiments, the number of the cover 300 is one.

In this embodiment, when the cover 300 is in the open state, the first end surface 161 and the second end surface 340 together form the insertion surface 11 of the power adapter 10, and the first end surface 161 is flush with the second end surface 340.

The plugging surface 11 of the power adapter 10 is a surface that is mated with the socket 50 when the pins 200 of the power adapter 10 are inserted into the socket 50, and the plugging surface 11 satisfies the safety requirements of the power adapter 10. When the plug 200 of the power adapter 10 is inserted into the receptacle 50, only the surface that is mated with the receptacle 50 but does not satisfy the safety regulations of the power adapter 10 cannot be referred to as the plug surface 11 of the power adapter 10. Specifically, for the power adapter 10, when the pins 200 of the power adapter 10 are inserted into the sockets 50, in order to prevent the power of the sockets 50 from leaking out through the pins 200 and causing injury to users, the distance between the edge of the pin 200 and the edge of the plugging surface 11 needs to be greater than or equal to a preset distance (also referred to as a safety distance). In the present embodiment, when the cover 300 is in the open state, the distance between the edge of the pin 200 adjacent to the cover 300 and the edge of the cover 300 away from the pin 200 is greater than or equal to a predetermined distance. For example, for the power adapter 10 suitable for china, the predetermined distance is 6.5 mm. For power adapters 10 suitable for use in other countries or regions, such as europe, the predetermined distance may be other values, such as 5.1mm, or 7.9 mm. In the schematic view of the present embodiment (as shown in fig. 4), when the first cover 310 and the second cover 320 are opened relatively, the distance from the leftmost side of the pin 200 to the surface of the first cover 310 facing away from the adapter body 100 (i.e., the leftmost surface of the first cover 310) is greater than or equal to the preset distance; likewise, the rightmost distance of the pins 200 is greater than or equal to the preset distance from the surface of the second cover body 320 facing away from the adapter body 100 (i.e., the rightmost surface of the second cover body 320).

Specifically, when the cover 300 includes the first cover 310 and the second cover 320, when the first cover 310 and the second cover 320 are both in the open state: the distance between the edge of the pins adjacent to the first cover body 310 and the edge of the first cover body 310 facing away from the pins is greater than or equal to 6.5mm, and the distance between the edge of the pins adjacent to the second cover body 320 and the edge of the second cover body 320 facing away from the pins is greater than or equal to 6.5mm, so as to meet the requirements of the safety regulations of the power adapter 10 applicable to china.

For power adapters 10 suitable for use in other countries or regions, such as europe, the distance between the edge of the pin adjacent to the first cover 310 and the edge of the first cover 310 facing away from the pin is greater than or equal to 5.1mm, and the distance between the edge of the pin adjacent to the second cover 320 and the edge of the second cover 320 facing away from the pin is greater than or equal to 5.1 mm. Alternatively, the distance between the edge of the pin adjacent to the first cover 310 and the edge of the first cover 310 facing away from the pin is greater than or equal to 7.9mm, and the distance between the edge of the pin adjacent to the second cover 320 and the edge of the second cover 320 facing away from the pin is greater than or equal to 7.9 mm.

In the related art (not the related art), the end face of the adapter body 100 provided with the pins 200 in the power adapter 10 constitutes the plugging face 11 of the power adapter 10, in other words, the plugging face 11 of the power adapter 10 in the related art power adapter 10 is formed only by the end face of the adapter body 100 provided with the pins 200, and therefore, in the related art, the thickness of the adapter body 100 is generally thick. For example, in order to meet the requirements of the safety regulations of the power adapter 10, the thickness of the body of the power adapter 10 (i.e. the width of the plugging surface 11 of the power adapter 10) is set to a preset thickness (e.g. 22mm), and the thickness of the adapter body 100 of the present application and the adapter body 100 of the related art are analyzed below. Since the mating face 11 of the adapter body 100 is formed only by the end face of the adapter body 100 where the pins 200 are provided in the related art, the thickness of the adapter body 100 of the power adapter 10 in the related art is thick. In the power adapter 10 of the present application, the second end surface 340 of the cover 300 and the first end surface 161 of the adapter body 100, on which the pins 200 are disposed, together form the plugging surface 11 of the power adapter 10, that is, the sum of the thickness of the adapter body 100 and the thickness of the cover 300 is equal to the predetermined thickness. In other words, the first end surface 161 of the adapter body 100 provided with the pins 200 in the power adapter 10 of the present application is only used as a part of the plugging surface 11 of the power adapter 10, that is, the size (i.e., the thickness of the adapter body 100) of the first end surface 161 of the adapter body 100 provided with the pins 200 in the power adapter 10 of the present application cannot satisfy the requirement of safety regulations, but needs to satisfy the requirement of safety regulations by means of the cover 300. As can be seen, the thickness of the adapter body 100 in the power adapter 10 of the present application is necessarily smaller than the thickness of the adapter body 100 in the related art. As can be seen, the thickness of the adapter body 100 in the power adapter 10 of the present application is thinner than the thickness of the adapter body 100 in the power adapter 10 of the related art.

Compared with the related art, in the power adapter 10 provided by the present application, the cover 300 is connected to the adapter body 100 and slides relative to the adapter body 100, and when the cover 300 is in the closed state, the pins 200 can be protected from being damaged and other objects can be prevented from being damaged by the pins 200. When the power adapter 10 needs to be used, the cover 300 is opened to expose the pins 200. Further, the second end surface 340 of the cover 300 and the first end surface 161 of the adapter body 100 together form the plugging surface 11 of the power adapter 10, in other words, the first end surface 161 of the adapter body 100 only constitutes a part of the plugging surface 11 of the power adapter 10, and the thickness of the adapter body 100 can be made thinner, thereby being beneficial to the miniaturization of the power adapter 10. In addition, compared to other movement modes such as the cover 300 being turned over with respect to the adapter body 100, in the power adapter 10 according to the embodiment of the present invention, the cover 300 is slidable with respect to the adapter body 100, and when the cover 300 of the power adapter 10 is switched from the closed state to the open state, the vertical distance between the cover 300 and the pins 200 is kept constant or does not change greatly, so that the vertical distance between the fingers of the user operating the cover 300 and the pins 200 is kept constant or does not change greatly, and even when the power adapter 10 is connected to the socket 50, the distance between the fingers of the user and the pins 200 can still meet the requirement of safety regulations, and electric shock is not easily caused.

The thickness of the adapter body 100 refers to the maximum dimension of the adapter body 100 in the thickness direction.

The cover 300 includes a first cover 310 and a second cover 320. The first cover 310 is connected to the adapter body 100 and can slide relative to the adapter body 100, and the first cover 310 has a first sub-end surface 311. The second cover 320 is connected to the adapter body 100 and can slide relative to the adapter body 100, the second cover 320 has a second sub-end surface 321, wherein the second end surface 340 includes the first sub-end surface 311 and the second sub-end surface 321. When the first cover 310 and the second cover 320 are in the closed state, the first sub-end surface 311 and the second sub-end surface 321 are away from the adapter body 100; when the first cover body 310 and the second cover body 320 are both in an open state, the first sub-end surface 311 and the second sub-end surface 321 are respectively disposed on two opposite sides of the first end surface 161, and the first sub-end surface 311, the second sub-end surface 321 and the first end surface 161 together form the plugging surface 11 of the power adapter 10.

When the first cover 310 is in the closed state, the first sub-end surface 311 faces away from the adapter body 100, that is, the first sub-end surface 311 faces away from the first end surface 161 of the adapter body 100. When the first cover 310 is opened by sliding gradually compared to the adapter body 100 from the closed state, the first sub-end surface 311 gradually approaches the first end surface 161 of the adapter body 100 until the first sub-end surface 311 is flush or substantially flush with the first end surface 161 when the first cover 310 is completely opened compared to the adapter body 100. Accordingly, when the first cover 310 is in the open state compared to the adapter body 100, the first sub-end surface 311 is flush or substantially flush with the first end surface 161, and when the first cover 310 is gradually slid from the open state to the closed state compared to the adapter body 100, the first sub-end surface 311 gradually deviates from the first end surface 161 of the adapter body 100 until the first cover 310 is completely in the closed state compared to the adapter body 100, at this time, the distance between the first sub-end surface 311 and the first end surface 161 of the adapter body 100 is the farthest, and the length of the power adapter 10 is the longest.

Similarly, when the second cover 320 is in the closed state, the second sub-end surface 321 faces away from the adapter body 100, that is, the second sub-end surface 321 faces away from the first end surface 161 of the adapter body 100. When the second cover 320 is opened by sliding relative to the adapter body 100 from the closed state, the second sub-end surface 321 gradually approaches the first end surface 161 of the adapter body 100 until the second sub-end surface 321 is flush or substantially flush with the first end surface 161 when the second cover 320 is completely opened relative to the adapter body 100. Accordingly, when the second cover 320 is in the open state compared to the adapter body 100, the second sub-end surface 321 is flush or substantially flush with the first end surface 161, and when the second cover 320 is gradually slid from the open state to the closed state compared to the adapter body 100, the second sub-end surface 321 gradually deviates from the first end surface 161 of the adapter body 100 until the second cover 320 is completely in the closed state compared to the adapter body 100, at this time, the distance between the second sub-end surface 321 and the first end surface 161 of the adapter body 100 is the farthest, and the length of the power adapter 10 is the longest.

When the first cover 310 and the second cover 320 are both in an open state, the first cover 310 and the second cover 320 are stacked on opposite sides of the adapter body 100, respectively. Correspondingly, the first sub-end surface 311 and the second sub-end surface 321 are respectively disposed on two opposite sides of the first end surface 161. In other words, the first end surface 161 is interposed between the first sub-end surface 311 and the second sub-end surface 321. When the first cover 310 and the second cover 320 are both in the open state, the first sub-end surface 311, the second sub-end surface 321, and the first end surface 161 are flush, so that the pins 200 can be inserted into the socket 50 conveniently.

When the first cover 310 and the second cover 320 are both in the open state, the length of the power adapter 10 is the shortest; when the first cover 310 and the second cover 320 are both in the closed state, the length of the power adapter 10 is longest.

Referring to fig. 5 and fig. 6, fig. 5 is a schematic diagram illustrating dimensions of components of a power adapter according to an embodiment of the present disclosure when a first cover and a second cover are in a closed state; fig. 6 is a schematic diagram illustrating dimensions of respective components in the power adapter shown in fig. 5 when the first cover and the second cover are in an open state.

In the present embodiment, the range of the thickness D1 of the adaptor body 100 is: d1 is not less than 6.3mm and not more than 14 mm; the thickness D2 of the first cover 310 ranges from: 4.825mm is not less than D2 is not less than 7mm, and the range of the thickness D3 of the second cover body 320 is as follows: d3 is not less than 4.825mm and not more than 7 mm.

Due to safety regulations, the width of the pins 200 is typically 6.3mm for a power adapter 100 suitable for china. Therefore, the D1 is more than or equal to 6.3 mm. In order to make the power adapter 10 thinner and lighter, the thickness D1 of the adapter body 100 is less than or equal to 14 mm.

In one embodiment, the thickness D1 of the adaptor body 100 ranges from: d1 is not less than 9.65mm and not more than 14 mm; the thickness D2 of the first cover 310 ranges from: d2 is not less than 4.825mm and not more than 7 mm; the thickness D3 of the second cover 320 ranges from: d3 is not less than 4.825mm and not more than 7 mm.

In one embodiment, the thickness D2 of the first cover 310 and the thickness D3 of the second cover 320 are equal, and the sum of the thickness D2 of the first cover 310 and the thickness D3 of the second cover 320 is equal to the thickness D1 of the adapter body 100.

The selection of the above dimensions is not arbitrary but is designed in combination with the requirements of safety regulations in the power adapter 10. Specifically, when the first cover 310 and the second cover 320 are both in the open state, the distance between the side surfaces of the pins 200 adjacent to the first cover 310 and the outermost surface of the first cover 310 is required to be greater than or equal to 6.5mm, due to the requirement of safety regulations, so as to prevent the user from being injured by electricity leakage when the power adapter 10 is inserted into the socket 50 through the pins 200. Likewise, due to safety regulations, the side of the pins 200 adjacent to the second cover 320 must be spaced from the outermost surface of the second cover 320 by a distance greater than or equal to 6.5 mm. Since the width of the pin 200 is 6.3mm, also due to the requirements of safety regulations, the minimum value of the thickness D1 of the adapter body 100, the thickness D2 of the first cover 310, and the thickness D3 of the second cover 320 is 6.3mm +6.5mm + 19.3 mm. Then, when the sum of the thickness D2 of the first cover 310 and the thickness D3 of the second cover 320 is equal to the thickness D1 of the adaptor body 100, the minimum value of the thickness D1 of the adaptor body 100 is equal to 19.3 mm/2-9.65 mm. When the thickness of the first cover 310 is equal to that of the second cover 320, D2-D3-9.65 mm/2-4.825 mm. That is, the minimum value of the thickness of the first cover 310 is 4.825mm, and the minimum value of the thickness of the second cover 320 is 4.825 mm. Since the thickness of the adapter body 100 of the conventional power adapter 10 is usually greater than 14mm, in order to make the adapter body 100 of the power adapter 10 thinner, the upper limit of the adapter body 100 may be selected to be 14 mm. When the thicknesses of the first cover 310 and the second cover 320 are equal, and the sum of the thickness of the first cover 310 and the thickness of the second cover 320 is equal to the thickness of the adapter body 100, the upper limit of the thickness of the first cover 310 is 7mm, and the upper limit of the thickness of the second cover 320 is 7 mm.

The manner in which the first cover 310 and the second cover 320 are connected to the adapter body 100 will be described in detail below. Referring to fig. 7, fig. 7 is a cross-sectional view of the power adapter of fig. 2 along the line I-I. The power adapter 10 further includes a first slide assembly 400 and a second slide assembly 500. One end of the first sliding member 400 is rotatably connected to the first cover 310, and the other end of the first sliding member 400 is rotatably connected to the adaptor body 100, so that the first cover 310 can slide relative to the adaptor body 100. One end of the second sliding member 500 is rotatably connected to the second cover 320, and the other end of the second sliding member 500 is rotatably connected to the adapter body 100, so that the second cover 320 can slide relative to the adapter body 100.

In the present embodiment, the configuration of the first slider unit 400 is illustrated as being the same as that of the second slider unit 500. It is to be understood that, in other embodiments, the structure of the first sliding assembly 400 and the structure of the second sliding assembly 500 may be different, as long as the first sliding assembly 400 can enable the first cover 310 to be slidable relative to the adaptor body 100, and the second sliding assembly 500 can enable the second cover 320 to be slidable relative to the adaptor body 100.

The first slide assembly 400 includes a first connector 410. The first connector 410 has a first rotating portion 411, a first connecting portion 412, and a second rotating portion 413 connected in sequence. The first rotating portion 411 is rotatably connected to the first cover 310, and the second rotating portion 413 is rotatably connected to the adaptor body 100.

The manner of the rotational connection between the first rotating portion 411 and the first cover 310 will be described in detail as follows. In this embodiment, the first rotating portion 411 is provided with a mounting hole (blind hole or through hole), and correspondingly, the first cover 310 is provided with a mounting hole (blind hole or through hole), and a connecting rotating member (e.g., a pin shaft) is inserted into the mounting hole of the first rotating portion 411 and the mounting hole of the first cover 310, so that the first rotating portion 411 is rotatably connected with the first cover 310. The first rotating portion 411 and the first cover 310 may be rotatably connected in other manners, for example, a rotating member is disposed on the first rotating portion 411, a mounting hole is disposed on the first cover 310, the rotating member is disposed in the mounting hole, and the rotating member may rotate in the mounting hole, so that the first rotating portion 411 and the first cover 310 are rotatably connected. Or, a mounting hole is formed in the first rotating portion 411, a rotating member is arranged on the first cover body 310, the rotating member is arranged in the mounting hole, and the rotating member can rotate in the mounting hole, so that the first rotating portion 411 is rotatably connected with the first cover body 310.

The manner in which the second rotating portion 413 is rotatably coupled to the adaptor body 100 will be described in detail below. In this embodiment, the second rotating portion 413 is provided with a mounting hole, and correspondingly, the adapter body 100 is provided with a mounting hole, and a connecting rotating member (e.g., a pin) is inserted into the mounting hole of the second rotating portion 413 and the mounting hole of the adapter body 100, so that the second rotating portion 413 is rotatably connected to the adapter body 100. Accordingly, the second rotating portion 413 may be rotatably connected to the adapter body 100 in other manners, for example, a rotating member is disposed on the second rotating portion 413, a mounting hole is disposed on the adapter body 100, the rotating member is disposed in the mounting hole, and the rotating member is rotatable in the mounting hole, so that the second rotating portion 413 is rotatably connected to the adapter body 100. Or, a mounting hole is formed in the second rotating portion 413, a rotating member is arranged on the adapter body 100, the rotating member is arranged in the mounting hole, and the rotating member can rotate in the mounting hole, so that the second rotating portion 413 is rotatably connected with the adapter body 100.

Further, in the present embodiment, the adaptor body 100 further has a first surface 162 and a second surface 163. The first surface 162 and the second surface 163 are respectively connected to the first end surface 161, and the first surface 162 is opposite to the second surface 163. The first surface 162 is disposed adjacent to the first cover 310 and the second surface 163 is disposed adjacent to the second cover 320. The first slide assembly 400 also includes a second link 420. The second connector 420 has a third rotation portion 421, a second connection portion 422, and a fourth rotation portion 423 that are sequentially connected, the third rotation portion 421 is rotatably connected to the first cover 310, and the fourth rotation portion 423 is rotatably connected to the adapter body 100; the connection point of the second rotating portion 413 and the adapter body 100 and the connection point of the fourth rotating portion 423 and the adapter body 100 are both away from the first surface 162.

When the first cover 310 and the second cover 320 are both in the closed state, the first surface 162 and the second surface 163 both constitute a partial appearance surface of the power adapter 10. When the first cover 310 and the second cover 320 are both in the open state, the first surface 162 is at least partially shielded by the first cover 310, and the second surface 163 is at least partially shielded by the second cover 320.

In the present embodiment, the third rotating portion 421 is rotatably coupled to the first cover 310 in the same manner as the first rotating portion 411 is rotatably coupled to the first cover 310. In this embodiment, the third rotating portion 421 is provided with a mounting hole, and correspondingly, the first cover 310 is provided with a mounting hole, and a connecting rotating member is inserted into the mounting hole of the third rotating portion 421 and the mounting hole of the first cover 310, so that the third rotating portion 421 is rotatably connected with the first cover 310. The third rotating portion 421 and the first cover 310 may be rotatably connected in other manners, for example, a rotating member is disposed on the third rotating portion 421, a mounting hole is disposed on the first cover 310, the rotating member is disposed in the mounting hole, and the rotating member can rotate in the mounting hole, so that the third rotating portion 421 and the first cover 310 are rotatably connected. Or, a mounting hole is formed in the third rotating portion 421, a rotating member is arranged on the first cover 310, the rotating member is arranged in the mounting hole, and the rotating member can rotate in the mounting hole, so that the third rotating portion 421 is rotatably connected with the first cover 310. It is understood that, in other embodiments, the third rotating portion 421 and the first cover 310 are rotatably connected in a different manner than the first rotating portion 411 and the first cover 310.

In the present embodiment, the fourth rotating portion 423 is rotatably coupled to the adaptor body 100 in the same manner as the second rotating portion 413 is rotatably coupled to the adaptor body 100. In this embodiment, the fourth rotating portion 423 is provided with a mounting hole, and correspondingly, the adapter body 100 is provided with a mounting hole, and a connecting rotating member (e.g., a pin shaft) is inserted into the mounting hole of the fourth rotating portion 423 and the mounting hole of the adapter body 100, so that the fourth rotating portion 423 is rotatably connected to the adapter body 100. Accordingly, the fourth rotating portion 423 may be rotatably connected to the adapter body 100 in other manners, for example, a rotating member is disposed on the fourth rotating portion 423, a mounting hole is disposed on the adapter body 100, the rotating member is disposed in the mounting hole, and the rotating member is rotatable in the mounting hole, so that the fourth rotating portion 423 is rotatably connected to the adapter body 100. Or, a mounting hole is formed in the fourth rotating portion 423, a rotating member is arranged on the adapter body 100, the rotating member is arranged in the mounting hole, and the rotating member can rotate in the mounting hole, so that the fourth rotating portion 423 is rotatably connected with the adapter body 100. It is understood that, in other embodiments, the fourth rotating portion 423 is rotatably connected to the adaptor body 100 in a different manner from the second rotating portion 413 is rotatably connected to the adaptor body 100.

The connection point of the second rotating portion 413 and the adapter body 100 and the connection point of the fourth rotating portion 423 and the adapter body 100 are both away from the first surface 162, so that the thickness space size of the adapter body 100 can be saved, and the thickness of the power adapter 10 is made to be thinner.

In the schematic diagram of the present embodiment, the first sliding assembly 400 includes the first connecting element 410 and the second connecting element 420 as an example, and it is understood that in other embodiments, the first sliding assembly 400 includes the first connecting element 410 and does not include the second connecting element 420. When the first sliding assembly 400 includes the first connecting member 410 and the second connecting member 420, the first cover 310 can be stably connected to the adaptor body 100, so that the first cover 310 is stable in movement, less prone to shaking and less prone to tilting and swinging compared to the adaptor body 100.

In this embodiment, the rotating connection member is taken as an example for illustration. The first rotating part 411 of the first connector 410 is fixed to the first cover 310 through a rotating connector, and the second rotating part 413 of the first connector 410 is fixed to the adaptor body 100 through a rotating connector; the third rotating portion 421 of the second link 420 is fixed to the first cover 310 by a rotating link, and the fourth rotating portion 423 of the second link 420 is fixed to the adapter body 100 by a rotating link. In this embodiment, the adaptor body 100, the first connector 410, the second connector 420 and the first cover 310 form a four-bar mechanism. The adaptor body 100 serves as a frame of the four-bar mechanism, the first connecting member 410 and the second connecting member 420 serve as side links of the four-bar mechanism, and the first cover 310 serves as a link assembly of the four-bar mechanism.

Referring to fig. 8 to 10 together, fig. 8 is a schematic diagram illustrating relationships among components of the power adapter shown in fig. 7; FIG. 9 is a schematic view of the power adapter shown in FIG. 3 in a semi-open state; FIG. 10 is a schematic view of the power adapter depicted in FIG. 9 from another angle. A connection point at which the first rotating portion 411 and the first cover 310 rotate is a first connection point P1, a connection point at which the second rotating portion 413 and the adapter body 100 rotate is a second connection point P2, a connection point at which the third rotating portion 421 and the first cover 310 rotate is a third connection point P3, when the first cover 310 is in a closed state, the third connection point P3 is disposed away from the first end surface 161 in comparison with the first connection point P1, a connection point at which the fourth rotating portion 423 and the adapter body 100 are connected is a fourth connection point P4, and the fourth connection point P4 is disposed adjacent to the first end surface 161 in comparison with the second connection point P2; a line L1 connecting the first connection point P1 and the third connection point P3 is parallel to a line L2 connecting the second connection point P2 and the fourth connection point P4.

The power adapter 10 is provided with the connection line L1 between the first connection point P1 and the third connection point P3 parallel to the connection line L2 between the second connection point P2 and the fourth connection point P4, so that the first cover 310 is stable and is not easy to shake and swing obliquely when moving relative to the adapter body 100.

The semi-open state refers to a state between an open state and a closed state. Specifically, when the first cover 310 is in the half-open state, the first cover 310 is in a state between the closed state and the half-open state; when the second cover 320 is in the half-open state, the second cover 320 is in a state between the closed state and the half-open state. When the first cover 310 and the second cover 320 are both in the half-open state, the power adapter 10 may be considered to be in the half-open state. Accordingly, when the first cover 310 and the second cover 320 are both in the open state, the power adapter 10 may be considered to be in the open state; when the first cover 310 and the second cover 320 are both in the closed state, the power adapter 10 is in the closed state.

In the schematic view of the present embodiment, when the first cover 310 and the second cover 320 are in the half-open state, the pins 200 are partially or completely exposed, and when the first cover 310 and the second cover 320 are in the half-open state, the pins 200 are completely exposed. As can be seen from the schematic diagram of the power adapter 10 in the half-open state, the second connector 420 is adjacent to the first end surface 161 compared to the first connector 410, and the second connector 420 partially shields the first connector 410. As can be seen from the schematic diagram of the power adapter 10 in the open state, the first connector 410 is completely hidden by the second connector 420. Of course, in other embodiments, when the power adapter 10 is in the open state, the first connector 410 is partially shielded by the second connector 420. For example, when the thickness of the first connector 410 is greater than the thickness of the first connector 410, and the opening width of the first end surface 161 is greater than the thickness of the first connector 410, when the power adapter 10 is in the open state, the first connector 410 is partially covered by the second connector 420.

In summary, the third connection point P3 is disposed away from the first end surface 161 compared to the first connection point P1, and the fourth connection point P4 is disposed adjacent to the first end surface 161 compared to the second connection point P2, so that when the first cover body 310 and the second cover body 320 are both in the open state, the first connection element 410 is partially or completely shielded by the second connection element 420. Therefore, the third connection point P3 is disposed away from the first end surface 161 compared to the first connection point P1, and the fourth connection point P4 is disposed adjacent to the first end surface 161 compared to the second connection point P2, so that the width of the opening formed on the first end surface 161 and the thickness of the second connector 420 are matched, and thus the width of the opening formed on the first end surface 161 is small, so that dust and the like are not easily introduced into the interior of the adapter body 100 through the opening. The fact that the width of the opening formed in the first end surface 161 is matched with the thickness of the second connector 420 means that the width of the opening formed in the first end surface 161 is equal to the thickness of the second connector 420 or larger than the preset thickness of the connector. The value of the predetermined dimension is usually small, for example, 0.02 mm.

In the present embodiment, the distance between the first connection point P1 and the second connection point P2 is equal to the distance between the third connection point P3 and the fourth connection point P4.

A distance between the first connection point P1 and the second connection point P2 is a first distance, and a distance between the third connection point P3 and the fourth connection point P4 is a second distance, wherein the first distance is equal to the second distance. The first distance is equal to the second distance, which is beneficial for the first sub-end surface 311 to be flush with the second end surface 340 when the first cover body 310 is opened, and the first cover body 310 fits the adapter body 100.

Referring to fig. 7 and 11 together, fig. 11 is a schematic cross-sectional view of the power adapter when it is fully opened. The third rotating portion 421, the second connecting portion 422, and the fourth rotating portion 423 are sequentially bent and connected to form an escape space 425 facing the first connecting member 410. The escape space 425 is used to avoid interference between the first connector 410 and the second connector 420 when the first cover 310 is in the closed state, and the first connection portion 412 abuts against the fourth rotation portion 423; when the first cover 310 is in the open state, the first rotating portion 411 abuts against the third rotating portion 421.

The avoidance space 425 can avoid interference when the first connector 410 and the second connector 420 rotate, in other words, due to the existence of the avoidance space 425, the first cover body 310 can rotate relative to the adapter body 100, and further the first cover body 310 can be switched between the closed state and the open state. In addition, when the first connection portion 412 abuts against the fourth rotation portion 423, the first cover 310 cannot be closed any more than the adapter body 100, so that the first cover 310 is in a closed state. When the first rotating portion 411 abuts against the third rotating portion 421, the first cover 310 cannot be opened further than the adapter body 100, so that the first cover 310 is in an opened state. Therefore, the structural design of the first connecting piece 410 and the second connecting piece 420 can prevent the first connecting piece 410 and the second connecting piece 420 from interfering when the first cover body 310 rotates relative to the adapter body 100, so as to ensure the smoothness of the first cover body 310 when the first cover body 310 rotates relative to the adapter body 100; on the other hand, the first cover 310 may be enabled to be in an opened state and a closed state.

Referring to fig. 10 and 11, the first end surface 161 has an opening, when the first cover 310 is in an open state, a surface of the fourth rotating portion 423 facing away from the first connecting member 410 is exposed at the opening, and a surface of the fourth rotating portion 423 facing away from the first connecting member 410 does not protrude from the first end surface 161.

When the first cover 310 is in the open state, a surface of the fourth rotating portion 423 facing away from the first connector 410 is exposed to the opening, and a surface of the fourth rotating portion 423 facing away from the first connector 410 does not protrude from the first end surface 161, including: the surface of the fourth rotating part 423 facing away from the first connector 410 is lower than the first end surface 161, or the surface of the fourth rotating part 423 facing away from the first connector 410 is flush with the first end surface 161. When the first cover 310 is in the open state, the surface of the fourth rotating portion 423 facing away from the first connector 410 does not protrude from the first end surface 161, so that the portion of the fourth rotating portion 423 exposed through the opening is prevented from affecting the use of the power adapter 10. Specifically, the insertion of the pins 200 of the power adapter 10 into the receptacle 50 is not affected.

In this embodiment, a surface of the fourth rotating portion 423 facing away from the first connecting portion 412 is an arc surface, and when the first cover 310 is opened, the arc surface is exposed to the opening of the first end surface 161, so that the appearance of the first cover 310 exposed to the opening is more attractive.

In addition, a surface of the fourth rotating portion 423 facing away from the first connecting portion 412 may be flush with a front end arc surface of the adaptor body 100.

With reference to fig. 10, the number of the first sliding elements 400 is two, two first sliding elements 400 are disposed at intervals, and the pins 200 are located between the two first sliding elements 400 when the first cover 310 is in the closed state.

The number of the first sliding assemblies 400 is two, so that the first cover 310 moves relatively smoothly when moving relative to the adapter body 100, and is not prone to shaking. In addition, when the first cover 310 is in the closed state, the pins 200 are located between the two first sliding assemblies 400, in other words, one of the first sliding assemblies 400 is disposed on one side of the two pins 200, and the other first sliding assembly 400 is disposed on the other side of the two pins 200, so that the movement of the first cover 310 relative to the adapter body 100 is more stable and less prone to generate wobbling. In addition, the above-mentioned position of the first sliding member 400 can make the first sliding member 400 convenient to set.

Referring to fig. 10, the number of the second sliding elements 500 is two, the two second sliding elements 500 are disposed at intervals, when the second cover 320 is in the closed state, the pin 200 is disposed between the two second sliding elements 500, and the first sliding element 400 located on the same side of the pin 200 and the second sliding element 500 in the second sliding element 500 are away from the pin 200.

The number of the second sliding assemblies 500 is two, so that the second cover 320 moves more stably and is less prone to shaking than the adapter body 100. In addition, when the second cover 320 is in the closed state, the pins 200 are located between the two second sliding assemblies 500, in other words, one of the second sliding assemblies 500 is disposed on one side of the two pins 200, and the other two first sliding assemblies 400 are disposed on the other side of the two pins 200, so that the movement of the second cover 320 relative to the adapter body 100 is more stable and less prone to generate wobbling. In addition, the above-mentioned position of the second sliding assembly 500 can make the second sliding assembly 500 convenient to set.

Referring to fig. 10 and 12 together, fig. 12 is a cross-sectional view taken along line III-III of the power adapter in fig. 10 in a half-open state. The second cover 320 has a third surface 323 and a fourth surface 324. The third surface 323 and the fourth surface 324 are respectively connected to the second sub-end surface 321, the third surface 323 forms a part of an external surface of the power adapter 10, the fourth surface 324 is opposite to the third surface 323, the fourth surface 324 has a limiting portion 3241, and the limiting portion 3241 is used to prevent the second sliding assembly 500 from shaking.

In this embodiment, the limiting portion 3241 is a groove. Referring to fig. 12, in the present embodiment, the fourth surface 324 further includes a first receiving portion 3242 and a second receiving portion 3243. When the first cover 310 and the second cover 320 are in the closed state: the first receiving portion 3242 is used for receiving at least a portion of the first connector 410 and at least a portion of the second connector 420, and the second receiving portion 3243 is used for receiving the pin 200.

It should be understood that, in the present embodiment, the fourth surface 324 is exemplified to have the limiting portion 3241, the first receiving portion 3242 and the second receiving portion 3243, and in other embodiments, when the first cover 310 and the second cover 320 are both closed, the surface of the first cover 310 facing the second cover 320 is provided with the limiting portion 3241, the first receiving portion 3242 and the second receiving portion 3243. In another embodiment, the stopper portion 3241, the first receiving portion 3242, and the second receiving portion 3243 are partially disposed on the first cover 310, and are partially disposed on the second cover 320. In another embodiment, a part of the second receiving portion 3243 is formed on the first cover 310, and another part is formed on the second cover 320.

In other words, the second receiving portion 3243 is disposed in at least one of the first cover 310 and the second cover 320. The second receiving portion 3243 is also called as a receiving cavity, and is used for receiving the pins 200 therein when the first cover 310 is closed relative to the second cover 320.

In the present embodiment, the first housing portion 3242 is a groove, and the second housing portion 3243 is also a groove.

Referring to fig. 2 and 13 together, fig. 13 is a cross-sectional view of the power adapter shown in fig. 2 along line IV-IV. In this embodiment, the power adapter 10 further includes: a first magnetic member 600 and a second magnetic member 700. For convenience of illustration, the first slide module 400 and the second slide module 500 are omitted in the schematic view of the present embodiment. The first magnetic member 600 is carried on the first cover 310. The second magnetic member 700 is carried by the second cover 320. When the first cover 310 and the second cover 320 are both in the closed state, the magnetic force between the first magnetic element 600 and the second magnetic element 700 makes the first cover 310 and the second cover 320 fixed on the same side of the first end surface 161; when the first cover 310 and the second cover 320 are both in the open state, the magnetic force between the first magnetic member 600 and the second magnetic member 700 makes the first cover 310 and the second cover 320 fixed to the adapter body 100, respectively.

Specifically, the first magnetic member 600 includes a first magnetic pole and a second magnetic pole, and the second magnetic member 700 also includes a first magnetic pole and a second magnetic pole. Wherein the first magnetic pole is an N pole, and the second magnetic pole is an S pole; alternatively, the first magnetic pole is an S pole, and the second magnetic pole is an N pole. When the first cover 310 and the second cover 320 are both in the closed state, the first magnetic pole of the first magnetic member 600 faces the second magnetic pole of the second magnetic member 700, and therefore, a magnetic attraction force is generated between the first magnetic member 600 and the second magnetic member 700, so that the first cover 310 and the second cover 320 are fixed together and are not easily separated.

The first magnetic member 600 may be, but is not limited to, a permanent magnet or an electromagnet, and accordingly, the second magnetic member 700 may be, but is not limited to, a permanent magnet or an electromagnet. In this embodiment, the first magnetic member 600 is a magnet, and the second magnetic member 700 is also a magnet.

In this embodiment, the first magnetic member 600 is carried by the first cover 310, and the first magnetic member 600 is disposed in a receiving space formed by the first cover 310. The second magnetic member 700 is carried by the second cover 320, and the second magnetic member 700 is disposed in a receiving space formed by the second cover 320.

Referring to fig. 14, fig. 14 is a schematic diagram illustrating a pushing force applied to the first cover in the power adapter in fig. 13. When the first cover 310 and the second cover 320 are both in the closed state, and a pushing force F is applied to the first cover 310 to slide the first cover 310, for example, when a user pushes the first cover 310 with a finger toward the adaptor body 100, the sliding of the first cover 310 also drives the second cover 320 to slide due to the magnetic force between the first magnetic member 600 and the second magnetic member 700 until the first cover 310 is in the open state and does not move, and the second cover 320 is in the open state and does not move. When the first cover 310 and the second cover 320 are both in the open state, the magnetic force between the first magnetic member 600 and the second magnetic member 700 makes the first cover 310 and the second cover 320 respectively fixed to two opposite sides of the adapter body 100.

Accordingly, when the first cover 310 and the second cover 320 are both in the open state, and a pushing force is applied to the first cover 310 to slide the first cover 310, for example, a user pushes the first cover 310 with a finger toward the plug 200, due to the magnetic force between the first magnetic member 600 and the second magnetic member 700, the sliding of the first cover 310 also drives the second cover 320 to slide the cover 300 until the first cover 310 is in the open state and does not move any more, and the second cover 320 is also in the open state and does not move any more. When the first cover 310 and the second cover 320 are both in the closed state, the magnetic force between the first magnetic element 600 and the second magnetic element 700 makes the first cover 310 and the second cover 320 fixed on the same side of the first end surface 161 of the adapter body 100.

When a pushing force is applied to the first cover 310 to slide the first cover 310, the sliding of the first cover 310 drives the sliding of the second cover 320 due to the magnetic force between the first magnetic element 600 and the second magnetic element 700. It can be understood that when the second cover 320 is slid by applying a pushing force to the second cover 320, the sliding of the second cover 320 drives the sliding of the first cover 310 due to the magnetic force between the first magnetic element 600 and the second magnetic element 700. In summary, due to the effects of the first magnetic element 600 and the second magnetic element 700, the synchronous movement between the first cover 310 and the second cover 320 can be achieved by applying a pushing force to any one of the first cover 310 and the second cover 320.

In this embodiment, the sixth rotating portion 513 is provided with a mounting hole, and correspondingly, the adapter body 100 is provided with a mounting hole, and a connecting rotating member (e.g., a pin shaft) is inserted into the mounting hole of the sixth rotating portion 513 and the mounting hole of the adapter body 100, so that the sixth rotating portion 513 is rotatably connected to the adapter body 100. Accordingly, the sixth rotating portion 513 may be rotatably connected to the adapter body 100 in other manners, for example, a rotating member is disposed on the sixth rotating portion 513, a mounting hole is disposed on the adapter body 100, the rotating member is disposed in the mounting hole, and the rotating member is rotatable in the mounting hole, so that the sixth rotating portion 513 is rotatably connected to the adapter body 100. Alternatively, a mounting hole is formed in the sixth rotating portion 513, a rotating member is arranged on the adapter body 100, the rotating member is arranged in the mounting hole, and the rotating member can rotate in the mounting hole, so that the sixth rotating portion 513 is rotatably connected with the adapter body 100.

Further, in the present embodiment, the adaptor body 100 further has a first surface 162 and a second surface 163. The first surface 162 and the second surface 163 are respectively connected to the first end surface 161, and the first surface 162 is opposite to the second surface 163. The first surface 162 is disposed adjacent to the first cover 310 and the second surface 163 is disposed adjacent to the second cover 320. The seventh rotating portion 521 is rotatably connected to the second cover 320, and the eighth rotating portion 523 is rotatably connected to the adaptor body 100; a connection point of the sixth rotating portion 513 to the adaptor body 100 and a connection point of the eighth rotating portion 523 to the adaptor body 100 are both away from the second surface 163.

In the present embodiment, the seventh rotating portion 521 is rotatably coupled to the second cover 320 in the same manner as the fifth rotating portion 511 is rotatably coupled to the second cover 320. In this embodiment, the seventh rotating portion 521 is provided with a mounting hole, correspondingly, the second cover 320 is provided with a mounting hole, and a connecting rotating member is inserted into the mounting hole of the seventh rotating portion 521 and the mounting hole of the second cover 320, so that the seventh rotating portion 521 and the second cover 320 are rotatably connected. For example, a rotating member is disposed on the seventh rotating portion 521, a mounting hole is disposed on the second cover 320, the rotating member is disposed in the mounting hole, and the rotating member can rotate in the mounting hole, so that the seventh rotating portion 521 is rotatably connected to the second cover 320.

It is understood that, in other embodiments, the seventh rotating portion 521 is rotatably connected to the second cover 320 in a different manner from the fifth rotating portion 511 is rotatably connected to the second cover 320.

In the present embodiment, the eighth rotating portion 523 is rotatably connected to the adaptor body 100 in the same manner as the sixth rotating portion 513 is rotatably connected to the adaptor body 100. In this embodiment, the eighth rotating portion 523 is provided with a mounting hole, and correspondingly, the adapter body 100 is provided with a mounting hole, and a connecting rotating member (e.g., a pin shaft) is inserted into the mounting hole of the eighth rotating portion 523 and the mounting hole of the adapter body 100, so that the eighth rotating portion 523 is rotatably connected with the adapter body 100. Correspondingly, the eighth rotating portion 523 may be rotatably connected to the adapter body 100 in other manners, for example, a rotating member is disposed on the eighth rotating portion 523, a mounting hole is disposed on the adapter body 100, the rotating member is disposed in the mounting hole, and the rotating member can rotate in the mounting hole, so that the eighth rotating portion 523 is rotatably connected to the adapter body 100.

It is understood that in other embodiments, the eighth rotating portion 523 is rotatably connected to the adaptor body 100 in a different manner than the sixth rotating portion 513 is rotatably connected to the adaptor body 100.

The connection point of the sixth rotating portion 513 and the adaptor body 100 and the connection point of the eighth rotating portion 523 and the adaptor body 100 are both away from the second surface 163, so that the thickness space size of the adaptor body 100 can be saved, and the thickness of the power adaptor 10 is made to be thinner.

In the schematic diagram of the present embodiment, the second sliding assembly 500 is illustrated as including the third connector 510 and the fourth connector 520, and it is understood that in other embodiments, the second sliding assembly 500 includes the third connector 510 and does not include the fourth connector 520. When the second sliding assembly 500 includes the third connecting member 510 and the fourth connecting member 520, the second cover 320 can be stably connected to the adapter body 100, so that the second cover 320 is stable and less prone to shake when moving compared to the adapter body 100.

The connection point of the second rotating portion 413 and the adapter body 100 and the connection point of the fourth rotating portion 423 and the adapter body 100 are both away from the first surface 162; and the connection point of the sixth rotating portion 513 and the adaptor body 100 and the connection point of the eighth rotating portion 523 and the adaptor body 100 are both away from the second surface 163, so that the first sliding assembly 400 and the second sliding assembly 500 are arranged in a staggered manner (see fig. 17 and 18), which is beneficial to saving the space of the power adaptor 10 and miniaturizing the power adaptor 10.

In the present embodiment, the fifth rotating portion 511 of the third link 510 is fixed to the second cover 320 by a pin, and the sixth rotating portion 513 of the third link 510 is fixed to the adaptor body 100 by a pin; the seventh rotating portion 521 of the fourth connecting member 520 is fixed to the second cover 320 by a pin, and the eighth rotating portion 523 is fixed to the adapter body 100 by a pin. In this embodiment, the adaptor body 100, the third link 510, the fourth link 520, and the second cover constitute another four-bar mechanism. The adapter body 100 serves as a frame of the four-bar mechanism, the third link 510 and the fourth link 520 serve as side links of the four-bar mechanism, and the second cover 320 serves as a link assembly of the four-bar mechanism.

Referring to fig. 19 to 21, fig. 19 is a schematic diagram illustrating connection points in the power adapter shown in fig. 15; FIG. 20 is a schematic view of various connection points in the power adapter shown in FIG. 16; fig. 21 is a schematic diagram of various connection points in the power adapter shown in fig. 17. The center of the rotational coupling member connecting the fifth rotating portion 511 and the second cover 320 is a fifth coupling point P5, the center of the rotational coupling member connecting the sixth rotating portion and the adaptor body 100 is a sixth coupling point P6, the center of the rotational coupling member connecting the seventh rotating portion 521 and the second cover 320 is a seventh coupling point P7, and the center of the rotational coupling member connecting the eighth rotating portion 523 and the adaptor body 100 is an eighth coupling point P8. A connecting line between the fifth connecting point P5 and the seventh connecting point P7 is parallel to a connecting line L4 between the sixth connecting point P6 and the eighth connecting point P8, so that when the second cover 320 slides relative to the adaptor body 100, the link assembly formed by the second cover 320, the third connecting member 510, the fourth connecting member 520 and the adaptor body 100 is always translated. The second cover 320 is relatively stable when moving relative to the adapter body 100, and is not prone to shaking and tilting.

In addition, due to the interaction between the first magnetic member 600 and the second magnetic member 700, the second cover 320 is driven to move when the first cover 310 moves, or the first cover 310 is driven to move when the second cover 320 moves. Since the link assembly (first link assembly) composed of the first cover 310, the first connector 410, the second connector 420, and the adapter body 100 is translated all the time when moving, and the link assembly (second link assembly) composed of the second cover 320, the third connector 510, the fourth connector 520, and the adapter body 100 is translated all the time when moving, when the first link assembly and the second link assembly move, the first link assembly and the second link assembly move all the time in parallel.

In addition, a connection point of the second rotating portion 413 and the adaptor body 100 and a connection point of the fourth rotating portion 423 and the adaptor body 100 are both away from the first surface 162; and the connection point of the sixth rotating portion 513 and the adaptor body 100 and the connection point of the eighth rotating portion 523 and the adaptor body 100 both face away from the second surface 163, so that the first sliding assembly 400 and the second sliding assembly 500 are arranged in a staggered manner, which is beneficial to saving the space of the power adaptor 10 and miniaturizing the power adaptor 10.

Specifically, the adapter body 100 serves as a frame of the first link assembly and the second link assembly, that is, a line connecting a center of the rotary connector of the adapter body 100 and a center of the rotary connector of the second rotating portion 413 and the fourth rotating portion 423 serves as one frame, and the frame is located at a lower portion of the adapter body 100, and is referred to as a first frame. When the first cover 310 slides, the first cover 310 moves around the first frame.

Similarly, a line connecting the center line of the rotary connection member connecting the sixth rotary portion 513 to the adapter body 100 and the center line of the rotary connection member connecting the eighth rotary portion 523 to the adapter body 100 serves as a frame, and the frame is located at the upper portion of the adapter body 100 and is referred to as a second frame. When the second cover 320 slides, the second cover 320 moves around the second frame.

It can be seen that the first slider and the second slider are arranged in a crossed manner, so that an upper first frame controls a lower second cover 320, and a lower second frame controls an upper first cover 310 in a crossed manner.

Referring to fig. 22, fig. 22 is a schematic structural diagram of the power adapter shown in fig. 2 in a half-open state. The first cover 310 further includes a first mating surface 312 facing away from the first sub-end 311, the second cover 320 further includes a second mating surface 322 facing away from the second sub-end 321, and accordingly, the adapter body 100 further includes a sidewall 112 connected between the first surface 162 and the second surface 163. The sidewall 112 includes a side surface 1121, and the side surface 1121 connects the first surface 162 and the second surface 163. The side wall 112 includes a first connecting surface 1122 and a second connecting surface 1123 connected in a bent manner. The first connection surface 1122 and the second connection surface 1123 are respectively connected to the side surfaces 1121, and the first connection surface 1122 and the second connection surface 1123 face the pins 200. When the first cover 310 is in the closed state, the first mating surface 312 faces the first connecting surface 1122; when the second cover 320 is in the closed state, the second mating surface 322 faces the second connecting surface 1123.

The connection point of the first connection surface 1122 and the second connection surface 1123 is an arc surface. The first connecting surface 1122 and the second connecting surface 1123 are both inclined surfaces, and correspondingly, the first mating surface 312 and the second mating surface 322 are both inclined surfaces, so that when the first cover 310 and the second cover 320 slide relative to the adapter body 100, the adapter body 100 is prevented from blocking the first cover 310 and the second cover 320, that is, the first connecting surface 1122 is avoided as the first mating surface 312, and the second connecting surface 1123 is avoided as the second mating surface 322, so that the first cover 310 and the second cover 320 slide more smoothly.

Referring to fig. 22, the surfaces of the first cover 310 and the second cover 320 are further provided with an operation portion 318, and the operation portion 318 facilitates a user to operate the first cover 310 and the second cover 320.

It is to be understood that, in other embodiments, the operation portion 318 is not disposed on the surface of the first cover 310 and the second cover 320, and when the user needs to use the power adapter 10, the user only needs to apply a pushing force to any one of the first sub-end surface 311 of the first cover 310 and the second sub-end surface 321 of the second cover 320.

Referring to fig. 23, fig. 23 is a schematic view of the power adapter shown in fig. 2 according to another angle. The power adapter 10 also includes a discharge interface 800.
