Description

Technical Field

[0001] This application relates to the field of electronic technologies, and particularly to a power adapter and an electronic device assembly. Background Art

[0002] With the progress of technologies, electronic devices such as mobile phones have become necessities in people's lives. A power adapter is usually used to charge electronic devices such as mobile phones.

[0003] Existing power adapters generally include an adapter body and pins exposed outside the adapter body. However, since the pins of existing adapters are entirely exposed, they are prone to damage. Summary of the Invention

[0004] This application provides a power adapter, which includes:

[0005] An adapter body having a first end face;

[0006] Pins exposed outside the first end face of the adapter body; and

[0007] A cover body connected to the adapter body and slidable relative to the adapter body, the cover body having a second end face; when the cover body is in a closed state, the pins are covered, and the second end face faces away from the adapter body; when the cover body is in an open state, the first end face and the second end face together form the plugging face of the power adapter.

[0008] This application also provides a power adapter, which includes an adapter body, pins, a first cover body, and a second cover body. The adapter body has a first end face exposing the pins. The first cover body and the second cover body are respectively slidably connected to the adapter body. The first cover body has a first sub-end face, and the second cover body has a second sub-end face. When at least one of the first cover body and the second cover body has a receiving cavity, when both the first cover body and the second cover body are in a closed state, the pins are received in the receiving cavity, and both the first sub-end face and the second sub-end face face away from the first end face; when both the first cover body and the second cover body are in an open state, the first cover body and the second cover body are respectively stacked on opposite sides of the adapter body to expose the pins, and the first end face, the first sub-end face, and the second sub-end face together form the plugging face of the power adapter.

[0009] This application also provides an electronic device assembly, which includes an electronic device and the power adapter as described above, and the power adapter is used to charge the electronic device.

[0010] In the power adapter provided by the present application, the cover is connected to the adapter body and is movable relative to the adapter body. When the cover is in the closed state, therefore, the pins can be protected from being damaged and other objects can be prevented from being damaged by the pins. When the power adapter needs to be used, the cover is opened to expose the pins. Further, the second end face of the cover and the first end face of the adapter body jointly form the plugging face of the power adapter. In other words, the first end face of the adapter body only constitutes a part of the plugging face of the power adapter, and the thickness of the adapter body can be made thinner, which is beneficial to the miniaturization of the power adapter.

[0037] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0038] Referring to "embodiment" or "embodiment" herein means that the specific features, structures or characteristics described in conjunction with the embodiment or embodiment may be included in at least one embodiment of this application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0039] This application provides a power adapter 10 (Power adapter). Please refer to Figure 1 , Figure 1 which is a schematic diagram of the application environment of the power adapter provided by an embodiment of this application. The so-called power adapter 10 is a conversion device that provides power supply for the electronic device 30. Generally, the power adapter 10 can convert an AC voltage into a DC 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, and the DC voltage is used to charge the electronic devices 30 such as mobile phones and computers. It can be understood that in other embodiments, the power adapter 10 converts the received AC voltage into a DC voltage, and the DC voltage is directly used by the electronic components in the electronic device 30. It can be understood that the schematic diagram of the application environment of the power adapter 10 only helps to understand the application of the power adapter 10, and should not be construed as a limitation of the power adapter 10 provided by this application.

[0040] Please refer to Figure 2 , Figure 3 and Figure 4, Figure 2 Schematic diagram when the cover of the power adapter provided in an embodiment of the present application is in a closed state; Figure 3 is Figure 2 Schematic diagram when the cover of the power adapter shown in Figure 4 is Figure 3 Schematic diagram of another angle of the power adapter shown in . 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 on the first end face 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 face 340. When the cover 300 is in a closed state, the pins 200 are covered, and the second end face 340 faces away from the adapter body 100; when the cover 300 is in an open state, the first end face 161 and the second end face 340 together form a plugging surface 11 of the power adapter 10.

[0041] It should be noted that the terms "first", "second", etc. in the description, claims, and the above-mentioned drawings of the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0042] The so-called adapter body 100 refers to the part that realizes the voltage conversion function of the power adapter 10. The adapter body 100 usually includes a circuit board for voltage conversion. In addition, the adapter body 100 may further include components such as a housing for accommodating the circuit board. The specific structure included in the adapter body 100 will be introduced in detail later in combination with the exploded view of the power adapter 10.

[0043] The pins 200 are made of metal. The pins 200 are plugged into a socket 50 to receive the AC voltage provided by the socket 50. The number of the pins 200 can be but is not limited to two. In this embodiment, the number of the pins 200 is two. The two pins 200 are opposite and spaced apart. The pins 200 can be but is not limited to being strip-shaped. The end of the pins 200 facing away from the socket 50 body is arc-shaped to facilitate the insertion of the pins 200 into the socket 50. When the pins 200 are inserted into the socket 50 to receive a first voltage, the circuit board 120 is electrically connected to the pins 200 to receive the first voltage transmitted by the pins 200, and the circuit board is used to convert the first voltage into a second voltage.

[0044] 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; or, the pins 200 are covered by the adapter body 100; or, the pins 200 are covered by both the adapter body 100 and the cover 300. Examples of the case where the pins 200 are covered by the cover 300 are as follows. The cover 300 has a receiving cavity. When the cover 300 is closed, the pins 200 are received in the receiving cavity to cover the pins 200. Examples of the case where the pins 200 are covered by the adapter body 100 are as follows. The adapter body 100 has a receiving cavity. When the cover 300 is closed, the pins 200 are received back into the receiving cavity. In this case, the pins 200 are covered by the adapter body 100. Examples of the case where the pins 200 are covered by both the adapter body 100 and the cover 300 are as follows. The adapter body 100 and the cover 300 jointly form a receiving cavity. When the cover 300 is closed, the pins 200 are received in the receiving cavity jointly formed by the adapter body 100 and the cover 300.

[0045] In the present embodiment, the manner in which the cover 300 is movably connected to the adapter body 100 is taken as an example for illustration, in which the cover 300 can slide relative to the adapter body 100. Specifically, reference can be made to the example in which 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 both slide relative to the adapter body 100. It can be understood that in other embodiments, the manner in which the cover 300 is connected to the adapter body 100 can also be other ways. For example, the cover is flipped multiple times and then the position of the cover is adjusted, etc. As long as the second end face 340 and the first end face 161 jointly form the plugging face 11 of the power adapter 10.

[0046] In the schematic diagram of the present embodiment, an example is illustrated in which the pins 200 are fixed to the adapter body 100 and exposed on the first plugging face 11. An example is illustrated in which the number of the covers 300 is two, that is, the cover 300 includes a first cover 310 and a second cover 320. It can be understood that in other embodiments, the number of the covers 300 is one.

[0047] In the present embodiment, when the cover 300 is in the open state, the first end face 161 and the second end face 340 jointly form the plugging face 11 of the power adapter 10, and the first end face 161 is flush with the second end face 340.

[0048] The so-called insertion surface 11 of the power adapter 10 refers to the surface that mates with the socket 50 when the pins 200 of the power adapter 10 are inserted into the socket 50, and the insertion surface 11 meets the requirements of the safety regulations of the power adapter 10. When the pins 200 of the power adapter 10 are inserted into the socket 50, the surface that only mates with the socket 50 but does not meet the safety regulations of the power adapter 10 cannot be called the insertion 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 socket 50, in order to prevent the electric energy of the socket 50 from leaking out through the pins 200 and causing harm to the user, the distance between the edge of the pins 200 and the edge of the insertion surface 11 needs to be greater than or equal to a preset distance (also known as the safety distance). In this embodiment, when the cover 300 is in the open state, the distance between the edge of the pins 200 adjacent to the cover 300 and the edge of the cover 300 facing away from the pins 200 is greater than or equal to the preset distance. For example, for the power adapter 10 applicable to China, the preset distance is 6.5 mm. For the power adapter 10 applicable to other countries or regions (such as Europe), the preset distance is other values, such as 5.1 mm, or 7.9 mm. In the schematic diagram of this embodiment (such as Figure 4 ), when the first cover 310 and the second cover 320 are opened relative to each other, the distance between the leftmost side of the pins 200 and 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; similarly, the distance between the rightmost side of the pins 200 and the surface of the second cover 320 facing away from the adapter body 100 (i.e., the rightmost surface of the second cover 320) is greater than or equal to the preset distance.

[0049] Specifically, when the cover 300 includes a first cover 310 and a second cover 320, when both the first cover 310 and the second cover 320 are in the open state: the distance between the edge of the pins adjacent to the first cover 310 and the edge of the first cover 310 facing away from the pins is greater than or equal to 6.5 mm, and the distance between the edge of the pins adjacent to the second cover 320 and the edge of the second cover 320 facing away from the pins is greater than or equal to 6.5 mm, so as to meet the requirements of the safety regulations of the power adapter 10 applicable to China.

[0050] For the power adapter 10 applicable to 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 5.1 mm, 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 7.9 mm, 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.

[0051] In the related art (not the prior art), the end face of the pin 200 provided on the adapter body 100 of 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 is only formed by the end face of the pin 200 provided on the adapter body 100. Therefore, in the related art, the thickness of the adapter body 100 is usually relatively thick. For example, in order to meet the requirements of the safety regulations of the power adapter 10, the thickness of the power adapter 10 body (i.e., the width of the plugging face 11 of the power adapter 10) is set to a preset thickness (such as 22 mm). Now, the thickness of the adapter body 100 in the present application and the adapter body 100 in the related art will be analyzed. Since in the related art, the plugging face 11 of the adapter body 100 is only formed by the end face of the pin 200 provided on the adapter body 100, the thickness of the adapter body 100 of the power adapter 10 in the related art is relatively thick. In the power adapter 10 of the present application, the second end face 340 of the cover 300 and the first end face 161 of the adapter body 100 provided with the pin 200 together constitute the plugging face 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 preset thickness. In other words, the first end face 161 of the adapter body 100 provided with the pin 200 in the power adapter 10 of the present application only serves as a part of the plugging face 11 of the power adapter 10. That is, the size of the first end face 161 of the adapter body 100 provided with the pin 200 in the power adapter 10 of the present application (i.e., the thickness of the adapter body 100) itself cannot meet the requirements of the safety regulations, and it needs to rely on the cover 300 to meet the requirements of the safety regulations. Thus, it can be seen that the thickness of the adapter body 100 in the power adapter 10 of the present application must be less than the thickness of the adapter body 100 in the related art. Thus, it can be seen that 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 of the power adapter 10 in the related art.

[0052] Compared with the related art, in the power adapter 10 provided by the present application, the cover body 300 is connected to the adapter body 100 and slides relative to the adapter body 100. When the cover body 300 is in the closed state, therefore, the pin 200 can be protected from being damaged and other objects can be prevented from being damaged by the pin 200. When the power adapter 10 needs to be used, the cover body 300 is opened to expose the pin 200. Further, the second end face 340 of the cover body 300 and the first end face 161 of the adapter body 100 together form the plugging face 11 of the power adapter 10. In other words, the first end face 161 of the adapter body 100 only constitutes a part of the plugging face 11 of the power adapter 10, and the thickness of the adapter body 100 can be made thinner, which is conducive to the miniaturization of the power adapter 10. In addition, compared with other movement modes such as the cover body 300 flipping relative to the adapter body 100, in the power adapter 10 provided by the embodiment of the present application, the cover body 300 can slide relative to the adapter body 100. When the cover body 300 of the power adapter 10 is switched from the closed state to the open state, the vertical distance between the cover body 300 and the pin 200 remains unchanged or changes little. Therefore, the vertical distance between the finger of the user operating the cover body 300 and the pin 200 remains unchanged or changes little. Even when the power adapter 10 is connected to the socket 50, the distance between the user's finger and the pin 200 can still meet the requirements of safety regulations and it is not easy to get an electric shock.

[0053] It should be noted that the so-called thickness of the adapter body 100 refers to the maximum dimension of the adapter body 100 in the thickness direction.

[0054] The cover body 300 includes a first cover body 310 and a second cover body 320. The first cover body 310 is connected to the adapter body 100 and can slide relative to the adapter body 100. The first cover body 310 has a first sub-end face 311. The second cover body 320 is connected to the adapter body 100 and can slide relative to the adapter body 100. The second cover body 320 has a second sub-end face 321. Among them, the second end face 340 includes the first sub-end face 311 and the second sub-end face 321. When the first cover body 310 and the second cover body 320 are in the closed state, the first sub-end face 311 and the second sub-end face 321 face away from the adapter body 100. When the first cover body 310 and the second cover body 320 are both in the open state, the first sub-end face 311 and the second sub-end face 321 are respectively arranged on two opposite sides of the first end face 161, and the first sub-end face 311, the second sub-end face 321 and the first end face 161 together form the plugging face 11 of the power adapter 10.

[0055] When the first cover 310 is in the closed state, the first sub-end face 311 faces away from the adapter body 100. The so-called first sub-end face 311 facing away from the adapter body 100 means that the first sub-end face 311 faces away from the first end face 161 of the adapter body 100. When the first cover 310 gradually slides relative to the adapter body 100 from the closed state to the open state, the first sub-end face 311 gradually approaches the first end face 161 of the adapter body 100. Until the first cover 310 is completely in the open state relative to the adapter body 100, the first sub-end face 311 is flush or substantially flush with the first end face 161. Correspondingly, when the first cover 310 is in the open state relative to the adapter body 100, the first sub-end face 311 is flush or substantially flush with the first end face 161. When the first cover 310 gradually slides relative to the adapter body 100 from the open state to the closed state, the first sub-end face 311 gradually moves away from the first end face 161 of the adapter body 100. Until the first cover 310 is completely in the closed state relative to the adapter body 100, at this time, the distance between the first sub-end face 311 and the first end face 161 of the adapter body 100 is the farthest, and the length of the power adapter 10 reaches the longest.

[0056] Similarly, when the second cover 320 is in the closed state, the second sub-end face 321 faces away from the adapter body 100. The so-called second sub-end face 321 facing away from the adapter body 100 means that the second sub-end face 321 faces away from the first end face 161 of the adapter body 100. When the second cover 320 gradually slides relative to the adapter body 100 from the closed state to the open state, the second sub-end face 321 gradually approaches the first end face 161 of the adapter body 100. Until the second cover 320 is completely in the open state relative to the adapter body 100, the second sub-end face 321 is flush or substantially flush with the first end face 161. Correspondingly, when the second cover 320 is in the open state relative to the adapter body 100, the second sub-end face 321 is flush or substantially flush with the first end face 161. When the second cover 320 gradually slides relative to the adapter body 100 from the open state to the closed state, the second sub-end face 321 gradually moves away from the first end face 161 of the adapter body 100. Until the second cover 320 is completely in the closed state relative to the adapter body 100, at this time, the distance between the second sub-end face 321 and the first end face 161 of the adapter body 100 is the farthest, and the length of the power adapter 10 reaches the longest.

[0057] When the first cover 310 and the second cover 320 are both in the open state, the first cover 310 and the second cover 320 are respectively stacked on two opposite sides of the adapter body 100. Accordingly, the first sub-end face 311 and the second sub-end face 321 are respectively disposed on two opposite sides of the first end face 161. In other words, the first end face 161 is clamped between the first sub-end face 311 and the second sub-end face 321. When the first cover 310 and the second cover 320 are both in the open state, the first sub-end face 311, the second sub-end face 321 and the first end face 161 are flush, so as to facilitate the insertion of the pin 200 into the socket 50.

[0058] When the first cover 310 and the second cover 320 are both in the open state, the power adapter 10 has the shortest length; when the first cover 310 and the second cover 320 are both in the closed state, the power adapter 10 has the longest length.

[0059] Please refer to Figure 5 and Figure 6 , Figure 5 which is a schematic diagram of the dimensions of each component when the first cover and the second cover in the power adapter provided by an embodiment of the present application are in the closed state; Figure 6 is Figure 5 a schematic diagram of the dimensions of each component when the first cover and the second cover in the power adapter shown in

[0060] In this embodiment, the range of the thickness D1 of the adapter body 100 is: 6.3 mm ≤ D1 ≤ 14 mm; the range of the thickness D2 of the first cover 310 is: 4.825 mm ≤ D2 ≤ 7 mm, and the range of the thickness D3 of the second cover 320 is: 4.825 mm ≤ D3 ≤ 7 mm.

[0061] Due to the requirements of safety regulations, for the power adapter 10 applicable to China, the width of the pin 200 is usually 6.3 mm. Therefore, D1 ≥ 6.3 mm. In order to make the power adapter 10 thinner and lighter, the thickness D1 of the adapter body 100 ≤ 14 mm.

[0062] In one embodiment, the range of the thickness D1 of the adapter body 100 is: 9.65 mm ≤ D1 ≤ 14 mm; the range of the thickness D2 of the first cover 310 is: 4.825 mm ≤ D2 ≤ 7 mm; the range of the thickness D3 of the second cover 320 is: 4.825 mm ≤ D3 ≤ 7 mm.

[0063] In one embodiment, the thickness D2 of the first cover 310 is equal to the thickness D3 of the second cover 320, 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.

[0064] The selection of the above dimensions is not arbitrary, but designed in combination with the requirements of safety regulations in the power adapter 10. Specifically, when both the first cover 310 and the second cover 320 are in the open state, due to the requirements of safety regulations, the distance from the side of the pin 200 adjacent to the first cover 310 to the outermost surface of the first cover 310 must be greater than or equal to 6.5 mm to prevent electric shock to the user when the power adapter 10 is inserted into the socket 50 through the pin 200. Similarly, due to the requirements of safety regulations, the distance from the side of the pin 200 adjacent to the second cover 320 to the outermost surface of the second cover 320 must be greater than or equal to 6.5 mm. Then, also due to the requirements of safety regulations, the width of the pin 200 is 6.3 mm. Therefore, 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 D1 + D2 + D3 = 6.3 mm + 6.5 mm + 6.5 mm = 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 adapter body 100, the minimum value of the thickness D1 of the adapter body 100 is equal to 19.3 mm / 2 = 9.65 mm. When the thickness of the first cover 310 is equal to the thickness 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 4.825 mm, 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 traditional power adapter 10 is usually greater than 14 mm, in order to make the adapter body 100 in the power adapter 10 of this case thinner, the upper limit of the adapter body 100 can be selected as 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 7 mm, and the upper limit of the thickness of the second cover 320 is 7 mm.

[0065] The following details the way the first cover 310 and the second cover 320 are connected to the adapter body 100. Please refer to Figure 7 , Figure 7 For Figure 2Schematic cross-sectional view of the power adapter along line I-I. The power adapter 10 further includes a first sliding assembly 400 and a second sliding assembly 500. One end of the first sliding assembly 400 is rotatably connected to the first cover 310, and the other end of the first sliding assembly 400 is rotatably connected to the adapter body 100, so that the first cover 310 can slide relative to the adapter body 100. One end of the second sliding assembly 500 is rotatably connected to the second cover 320, and the other end of the second sliding assembly 500 is rotatably connected to the adapter body 100, so that the second cover 320 can slide relative to the adapter body 100.

[0066] In this embodiment, the structure of the first sliding assembly 400 is the same as that of the second sliding assembly 500 as an example for illustration. It can be understood that in other embodiments, the structure of the first sliding assembly 400 and the structure of the second sliding assembly 500 can also be different, as long as the first sliding assembly 400 can make the first cover 310 slide relative to the adapter body 100, and the second sliding assembly 500 can make the second cover 320 slide relative to the adapter body 100.

[0067] The first sliding assembly 400 includes a first connecting member 410. The first connecting member 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 adapter body 100.

[0068] The way in which the first rotating part 411 is rotatably connected to the first cover 310 is introduced in detail as follows. In this embodiment, an installation hole (blind hole or through hole) is provided on the first rotating part 411. Correspondingly, an installation hole (blind hole or through hole) is provided on the first cover 310. A connecting rotating member (such as a pin shaft) is inserted into the installation hole on the first rotating part 411 and the installation hole on the first cover 310, so that the first rotating part 411 is rotatably connected to the first cover 310. The way in which the first rotating part 411 is rotatably connected to the first cover 310 can also be other ways. For example, a rotating member is provided on the first rotating part 411, an installation hole is provided on the first cover 310, the rotating member is arranged in the installation hole, and the rotating member can rotate in the installation hole, so that the first rotating part 411 is rotatably connected to the first cover 310. Or, an installation hole is provided on the first rotating part 411, a rotating member is provided on the first cover 310, the rotating member is arranged in the installation hole, and the rotating member can rotate in the installation hole, so that the first rotating part 411 is rotatably connected to the first cover 310.

[0069] The way in which the second rotating part 413 is rotatably connected to the adapter body 100 is introduced in detail as follows. In this embodiment, an installation hole is provided on the second rotating part 413. Correspondingly, an installation hole is provided on the adapter body 100. A connecting rotating member (such as a pin shaft) is inserted into the installation hole on the second rotating part 413 and the installation hole on the adapter body 100, so that the second rotating part 413 is rotatably connected to the adapter body 100. Correspondingly, the way in which the second rotating part 413 is rotatably connected to the adapter body 100 can also be other ways. For example, a rotating member is provided on the second rotating part 413, an installation hole is provided on the adapter body 100, the rotating member is arranged in the installation hole, and the rotating member can rotate in the installation hole, so that the second rotating part 413 is rotatably connected to the adapter body 100. Or, an installation hole is provided on the second rotating part 413, a rotating member is provided on the adapter body 100, the rotating member is arranged in the installation hole, and the rotating member can rotate in the installation hole, so that the second rotating part 413 is rotatably connected to the adapter body 100.

[0070] Further, in the present embodiment, the adapter 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 face 161, and the first surface 162 and the second surface 163 are disposed opposite to each other. The first surface 162 is adjacent to the first cover 310, and the second surface 163 is adjacent to the second cover 320. The first sliding assembly 400 further includes a second connecting member 420. The second connecting member 420 has a third rotating portion 421, a second connecting portion 422, and a fourth rotating portion 423 connected in sequence. The third rotating portion 421 is rotatably connected to the first cover 310, and the fourth rotating portion 423 is rotatably connected to the adapter body 100; the connection points of the second rotating portion 413 with the adapter body 100 and the connection points of the fourth rotating portion 423 with the adapter body 100 both face away from the first surface 162.

[0071] When both the first cover 310 and the second cover 320 are in the closed state, the first surface 162 and the second surface 163 both constitute part of the external appearance surface of the power adapter 10. When both the first cover 310 and the second cover 320 are in the open state, at least a part of the first surface 162 is blocked by the first cover 310, and at least a part of the second surface 163 is blocked by the second cover 320.

[0072] In this embodiment, the third rotating part 421 is rotatably connected to the first cover 310 in the same manner as the first rotating part 411 is rotatably connected to the first cover 310. In this embodiment, the third rotating part 421 is provided with a mounting hole. Correspondingly, the first cover 310 is provided with a mounting hole. A connecting rotating member is inserted into the mounting hole on the third rotating part 421 and the mounting hole of the first cover 310, so that the third rotating part 421 is rotatably connected to the first cover 310. The manner in which the third rotating part 421 is rotatably connected to the first cover 310 can also be other ways. For example, a rotating member is provided on the third rotating part 421, a mounting hole is provided 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 part 421 is rotatably connected to the first cover 310. Or, a mounting hole is provided on the third rotating part 421, a rotating member is provided 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 part 421 is rotatably connected to the first cover 310. It can be understood that in other embodiments, the manner in which the third rotating part 421 is rotatably connected to the first cover 310 is different from the manner in which the first rotating part 411 is rotatably connected to the first cover 310.

[0073] In this embodiment, the manner in which the fourth rotating portion 423 is rotatably connected to the adapter body 100 is the same as the manner in which the second rotating portion 413 is rotatably connected to the adapter body 100. In this embodiment, an installation hole is provided on the fourth rotating portion 423. Correspondingly, an installation hole is provided on the adapter body 100. A connecting rotating member (for example, a pin shaft) is inserted into the installation hole on the fourth rotating portion 423 and the installation hole on the adapter body 100, so that the fourth rotating portion 423 is rotatably connected to the adapter body 100. Correspondingly, the manner in which the fourth rotating portion 423 is rotatably connected to the adapter body 100 can also be other manners. For example, a rotating member is provided on the fourth rotating portion 423, an installation hole is provided on the adapter body 100, the rotating member is arranged in the installation hole, and the rotating member can rotate in the installation hole, so that the fourth rotating portion 423 is rotatably connected to the adapter body 100. Or, an installation hole is provided on the fourth rotating portion 423, a rotating member is provided on the adapter body 100, the rotating member is arranged in the installation hole, and the rotating member can rotate in the installation hole, so that the fourth rotating portion 423 is rotatably connected to the adapter body 100. It can be understood that in other embodiments, the manner in which the fourth rotating portion 423 is rotatably connected to the adapter body 100 is different from the manner in which the second rotating portion 413 is rotatably connected to the adapter body 100.

[0074] The connection point between the second rotating portion 413 and the adapter body 100 and the connection point between the fourth rotating portion 423 and the adapter body 100 both face away from the first surface 162, which can save the thickness space dimension of the adapter body 100 and make the thickness of the power adapter 10 thinner.

[0075] In the schematic diagram of this embodiment, an example is given with the first sliding assembly 400 including the first connecting member 410 and the second connecting member 420. It can be understood that in other embodiments, the first sliding assembly 400 includes the first connecting member 410 but does not include the second connecting member 420. When the first sliding assembly 400 includes the first connecting member 410 and also includes the second connecting member 420, the first cover 310 can be stably connected to the adapter body 100, and further, when the first cover 310 moves relative to the adapter body 100, it is relatively stable, not easy to shake, and not easy to deflect and swing.

[0076] In this embodiment, the rotating connecting piece is taken as a pin shaft for illustration. The first rotating part 411 of the first connecting piece 410 is fixed to the first cover body 310 through the rotating connecting piece, and the second rotating part 413 of the first connecting piece 410 is fixed to the adapter body 100 through the rotating connecting piece; and the third rotating part 421 of the second connecting piece 420 is fixed to the first cover body 310 through the rotating connecting piece, and the fourth rotating part 423 of the second connecting piece 420 is fixed to the adapter body 100 through the rotating connecting piece for illustration. In this embodiment, the adapter body 100, the first connecting piece 410, the second connecting piece 420 and the first cover body 310 form a four-bar mechanism. Among them, the adapter body 100 serves as the frame of the four-bar mechanism, the first connecting piece 410 and the second connecting piece 420 serve as the connecting rods of the four-bar mechanism, and the first cover body 310 serves as the connecting rod assembly of the four-bar structure.

[0077] Please refer to Figures 8 to 10 , Figure 8 for Figure 7 the schematic diagram of the relationship between various components in the power adapter shown in Figure 9 ; Figure 3 for Figure 10 the schematic diagram of the power adapter shown in Figure 9 in a semi-open state;

[0078] In the above-mentioned power adapter 10, the connection line L1 between the first connection point P1 and the third connection point P3 is parallel to the connection line L2 between the second connection point P2 and the fourth connection point P4, which can make the first cover body 310 move relatively smoothly with respect to the adapter body 100, not easy to shake, and not easy to deflect and swing.

[0079] The so-called semi-open state refers to the state between the open state and the closed state. Specifically, when the first cover 310 is in the semi-open state, the first cover 310 is in the state between the closed state and the semi-open state; when the second cover 320 is in the semi-open state, the second cover 320 is in the state between the closed state and the semi-open state. When both the first cover 310 and the second cover 320 are in the semi-open state, it can be considered that the power adapter 10 is in the semi-open state. Correspondingly, when both the first cover 310 and the second cover 320 are in the open state, it can be considered that the power adapter 10 is in the open state; when both the first cover 310 and the second cover 320 are in the closed state, the power adapter 10 is in the closed state.

[0080] When both the first cover 310 and the second cover 320 are in the semi-open state, part or all of the pins 200 are exposed. In the schematic diagram of this embodiment, when both the first cover 310 and the second cover 320 are in the semi-open state, all of the pins 200 are exposed. As can be seen from the schematic diagram of the power adapter 10 in the semi-open state, the second connecting member 420 is closer to the first end face 161 than the first connecting member 410, and the second connecting member 420 partially obscures the first connecting member 410. As can be seen from the schematic diagram of the power adapter 10 in the open state, the first connecting member 410 is completely obscured by the second connecting member 420. Of course, in other embodiments, when the power adapter 10 is in the open state, the first connecting member 410 is partially obscured by the second connecting member 420. For example, when the thickness of the first connecting member 410 is greater than the thickness of the first connecting member 410, and the opening width of the first end face 161 is greater than the thickness of the first connecting member 410, when the power adapter 10 is in the open state, the first connecting member 410 is partially obscured by the second connecting member 420.

[0081] In summary, the third connection point P3 is disposed away from the first end face 161 relative to the first connection point P1, and the fourth connection point P4 is disposed closer to the first end face 161 relative to the second connection point P2, so that when the first cover 310 and the second cover 320 are both in the open state, part or all of the first connecting member 410 is blocked by the second connecting member 420. Therefore, the third connection point P3 being disposed away from the first end face 161 relative to the first connection point P1, and the fourth connection point P4 being disposed closer to the first end face 161 relative to the second connection point P2 enables the width of the opening formed on the first end face 161 to be adapted to the thickness of the second connecting member 420, so that the width of the opening formed on the first end face 161 is small, making it difficult for dust and the like to enter the interior of the adapter body 100 through the opening. The so-called adaptation of the width of the opening formed on the first end face 161 to the thickness of the second connecting member 420 means that the width of the opening formed on the first end face 161 is equal to the thickness of the second connecting member 420 or greater than a preset dimension of the thickness of the connecting member. The value of the preset dimension is usually small, for example, 0.02 mm.

[0082] 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.

[0083] The distance between the first connection point P1 and the second connection point P2 is a first distance, and the 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 equality of the first distance and the second distance is beneficial for the first sub-end face 311 to be flush with the second end face 340 and the first cover 310 to fit the adapter body 100 when the first cover 310 is opened.

[0084] Please refer to Figure 7 and Figure 11 , Figure 11 is a schematic cross-sectional view when the power adapter is fully opened. The third rotating portion 421, the second connecting portion 422, and the fourth rotating portion 423 are bent and connected in sequence to form an avoidance space 425 facing the first connecting member 410. The avoidance space 425 is used to prevent interference between the first connecting member 410 and the second connecting member 420 during rotation, and when the first cover 310 is in the closed state, the first connecting portion 412 abuts against the fourth rotating portion 423; when the first cover 310 is in the open state, the first rotating portion 411 abuts against the third rotating portion 421.

[0085] The avoidance space 425 can prevent interference when the first connecting member 410 and the second connecting member 420 rotate. In other words, due to the existence of the avoidance space 425, the first cover 310 can rotate relative to the adapter body 100, so that the first cover 310 can be switched between the closed state and the open state. In addition, when the first connecting portion 412 abuts against the fourth rotating portion 423, the first cover 310 cannot continue to close relative to the adapter body 100, so that the first cover 310 is in the closed state. When the first rotating portion 411 abuts against the third rotating portion 421, the first cover 310 cannot continue to open relative to the adapter body 100, so that the first cover 310 is in the open state. It can be seen that the structural design of the first connecting member 410 and the second connecting member 420 can, on the one hand, prevent interference between the first connecting member 410 and the second connecting member 420 when the first cover 310 rotates relative to the adapter body 100, thus ensuring the smoothness of the rotation of the first cover 310 relative to the adapter body 100; on the other hand, it can make the first cover 310 be in the open state and the closed state.

[0086] Please continue to refer to Figure 10 and Figure 11 , the first end face 161 has an opening. When the first cover 310 is in the open state, the surface of the fourth rotating portion 423 facing away from the first connecting member 410 is exposed in the opening, and the surface of the fourth rotating portion 423 facing away from the first connecting member 410 does not protrude from the first end face 161.

[0087] When the first cover 310 is in the open state, the surface of the fourth rotating portion 423 facing away from the first connecting member 410 is exposed in the opening, and the surface of the fourth rotating portion 423 facing away from the first connecting member 410 does not protrude from the first end face 161 includes: the surface of the fourth rotating portion 423 facing away from the first connecting member 410 is lower than the first end face 161, or the surface of the fourth rotating portion 423 facing away from the first connecting member 410 is flush with the first end face 161. When the first cover 310 is in the open state, the surface of the fourth rotating portion 423 facing away from the first connecting member 410 does not protrude from the first end face 161, which can prevent the part of the fourth rotating portion 423 exposed through the opening from affecting the use of the power adapter 10. Specifically, it does not affect the insertion of the pin 200 of the power adapter 10 into the socket 50.

[0088] In this embodiment, the surface of the fourth rotating portion 423 facing away from the first connecting portion 412 is an arc surface. When the first cover 310 is opened, the arc surface is exposed at the opening of the first end face 161, which can make the appearance of the first cover 310 exposing the opening more beautiful.

[0089] In addition, the surface of the fourth rotating portion 423 facing away from the first connecting portion 412 can be flush with the front arc surface of the adapter body 100.

[0090] Please continue to refer to Figure 10 , the number of the first sliding components 400 is two, and the two first sliding components 400 are arranged at intervals. When the first cover 310 is in the closed state, the pins 200 are located between the two first sliding components 400.

[0091] The number of the first sliding components 400 is two, which can make the movement of the first cover 310 relative to the adapter body 100 more stable and 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 components 400. In other words, one of the first sliding components 400 is arranged on one side of the two pins 200, and the other first sliding component 400 is arranged on the other side of the two pins 200, which further makes the movement of the first cover 310 relative to the adapter body 100 more stable and not prone to shaking. In addition, the above positions of the first sliding components 400 can make the arrangement of the first sliding components 400 more convenient.

[0092] Please continue to refer to Figure 10 , the number of the second sliding components 500 is two, and the two second sliding components 500 are arranged at intervals. When the second cover 320 is in the closed state, the pins 200 are arranged between the two second sliding components 500, and the second sliding component 500 of the first sliding component 400 and the second sliding component 500 on the same side of the pins 200 faces away from the pins 200.

[0093] The number of the second sliding components 500 is two, which can make the second cover body 320 move more smoothly relative to the adapter body 100 and is not prone to shaking. In addition, when the second cover body 320 is in the closed state, the pins 200 are located between the two second sliding components 500. In other words, one of the second sliding components 500 is arranged on one side of the two pins 200, and the other two first sliding components 400 are arranged on the other side of the two pins 200, which further makes the second cover body 320 move more smoothly relative to the adapter body 100 and is not prone to shaking. In addition, the above positions of the second sliding components 500 can make the second sliding components 500 easier to set up.

[0094] Please refer to Figure 10 and Figure 12 , Figure 12 which is Figure 10 a cross-sectional view along line III-III when the power adapter in

[0095] is in the semi-open state. The second cover body 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 face 321. The third surface 323 constitutes a part of the appearance surface of the power adapter 10. The fourth surface 324 is arranged 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 component 500 from shaking. Figure 12 In this embodiment, the limiting portion 3241 is a groove. Please continue to refer to Figure 12 , in this embodiment, the fourth surface 324 further has a first storage portion 3242 and a second storage portion 3243. When the first cover body 310 and the second cover body 320 are in the closed state: the first storage portion 3242 is used to store at least part of the first connecting member 410 and at least part of the second connecting member 420, and the second storage portion 3243 is used to store the pins 200.

[0096] Understandably, in the present embodiment, the fourth surface 324 is taken as an example with a limiting portion 3241, a first receiving portion 3242, and a second receiving portion 3243. In other embodiments, when both the first cover 310 and the second cover 320 are 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 other embodiments, some of the limiting portion 3241, the first receiving portion 3242, and the second receiving portion 3243 are provided on the first cover 310, and the other parts are provided on the second cover 320. In other embodiments, a part of the second receiving portion 3243 is formed on the first cover 310, and the other part is formed on the second cover 320.

[0097] In other words, the second receiving portion 3243 is provided on at least one of the first cover 310 and the second cover 320. The second receiving portion 3243 is also referred to as a receiving cavity for receiving the pin 200 in the receiving cavity when both the first cover 310 and the second cover 320 are in a closed state relative to each other.

[0098] In the present embodiment, the first receiving portion 3242 is a groove, and the second receiving portion 3243 is also a groove.

[0099] Please refer to Figure 2 and Figure 13 , Figure 13 is Figure 2 a schematic cross-sectional view of the power adapter shown in along the line IV-IV. In the present embodiment, the power adapter 10 further includes: a first magnetic member 600 and a second magnetic member 700. For the convenience of illustration, the first sliding assembly 400 and the second sliding assembly 500 are omitted in the schematic diagram of the present embodiment. The first magnetic member 600 is carried on the first cover 310. The second magnetic member 700 is carried on the second cover 320. When both the first cover 310 and the second cover 320 are in a closed state, the magnetic force between the first magnetic member 600 and the second magnetic member 700 fixes the first cover 310 and the second cover 320 on the same side of the first end face 161; when both the first cover 310 and the second cover 320 are in an open state, the magnetic force between the first magnetic member 600 and the second magnetic member 700 fixes the first cover 310 and the second cover 320 to the adapter body 100 respectively.

[0100] 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. Among them, 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 both the first cover 310 and the second cover 320 are in a closed state, the first magnetic pole of the first magnetic member 600 faces the second magnetic pole of the second magnetic member 700. Therefore, a magnetic attraction force is generated between the first magnetic member 600 and the second magnetic member 700, thereby fixing the first cover 310 and the second cover 320 together and making it not easy to separate.

[0101] The first magnetic member 600 can be, but is not limited to, a permanent magnet or an electromagnet. Correspondingly, the second magnetic member 700 can 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.

[0102] In this embodiment, the first magnetic member 600 is carried on the first cover 310, including that the first magnetic member 600 is disposed in the receiving space formed by the first cover 310. The second magnetic member 700 is carried on the second cover 320, including that the second magnetic member 700 is disposed in the receiving space formed by the second cover 320.

[0103] Please continue to refer to Figure 14 , Figure 14 For Figure 13 a schematic diagram of applying a thrust to the first cover in the power adapter in

[0104] Accordingly, when both the first cover 310 and the second cover 320 are in the open state, when a thrust is applied to the first cover 310 to cause the first cover 310 to slide, for example, when the user pushes the first cover 310 in the direction of the pins 200 with a finger, due to the magnetic force between the first magnetic member 600 and the second magnetic member 700, the sliding of the first cover 310 will also drive the second cover 320 of the cover 300 to slide until the first cover 310 is in the open state and stops moving, and the second cover 320 is also in the open state and stops moving. When both the first cover 310 and the second cover 320 are in the closed state, the magnetic force between the first magnetic member 600 and the second magnetic member 700 fixes the first cover 310 and the second cover 320 on the same side of the first end face 161 of the adapter body 100.

[0105] When a thrust is applied to the first cover 310 to cause the first cover 310 to slide, due to the magnetic force between the first magnetic member 600 and the second magnetic member 700, the sliding of the first cover 310 will drive the second cover 320 to slide. It can be understood that when a thrust is applied to the second cover 320 to cause the second cover 320 to slide, due to the magnetic force between the first magnetic member 600 and the second magnetic member 700, the sliding of the second cover 320 will drive the first cover 310 to slide. In summary, due to the action of the first magnetic member 600 and the second magnetic member 700, a thrust only needs to be applied to any one of the first cover 310 and the second cover 320 to achieve the synchronous movement between the first cover 310 and the second cover 320.

[0106] Similarly, please also refer to Figures 15 to 17 , Figure 15 is Figure 2 a schematic cross-sectional view of the power adapter shown in Figure 16 along line II-II; Figure 15 is a cross-sectional view of the power adapter shown in Figure 17 in a semi-open state; Figure 15 is a cross-sectional view of the power adapter shown in Figure 15 in an open state. For the convenience of schematically showing the second sliding assembly 500, the first sliding assembly 400 is omitted in Figure 17 and The second sliding assembly 500 includes a third connecting member 510. One end of the third connecting member 510 is rotatably connected to the second cover 320, and the other end of the third connecting member 510 is rotatably connected to the adapter body 100. One end of the fourth connecting member 520 is rotatably connected to the second cover 320, and the other end of the fourth connecting member 520 is rotatably connected to the adapter body 100.

[0107] In this embodiment, the second sliding component 500 has the same structure as the first sliding component 400, the third connecting member 510 has the same structure as the first connecting member 410, and the fourth connecting member 520 has the same structure as the second connecting member 420.

[0108] Specifically, the third connecting member 510 includes a fifth rotating portion 511, a third connecting portion 512, and a sixth rotating portion 513 that are connected in sequence. The fifth rotating portion 511 is rotatably connected to the second cover 320, and the sixth rotating portion 513 is rotatably connected to the adapter body 100. The fourth connecting member 520 includes a seventh rotating portion 521, a fourth connecting portion 522, and an eighth rotating portion 523 that are connected in sequence. The seventh rotating portion 521 is rotatably connected to the second cover 320, and the eighth rotating portion 523 is rotatably connected to the adapter body 100.

[0109] The manner in which the fifth rotating portion 511 is rotatably connected to the second cover 320 is described in detail as follows. In this embodiment, an installation hole (blind hole or through hole) is provided on the fifth rotating portion 511. Correspondingly, an installation hole (blind hole or through hole) is provided on the second cover 320. A connecting rotating member (such as a pin shaft) is inserted into the installation hole on the fifth rotating portion 511 and the installation hole on the second cover 320, so that the fifth rotating portion 511 is rotatably connected to the second cover 320. The manner in which the fifth rotating portion 511 is rotatably connected to the second cover 320 can also be other manners. For example, a rotating member is provided on the fifth rotating portion 511, an installation hole is provided on the second cover 320, the rotating member is disposed in the installation hole, and the rotating member can rotate in the installation hole, so that the fifth rotating portion 511 is rotatably connected to the second cover 320. Or, an installation hole is provided on the fifth rotating portion 511, a rotating member is provided on the second cover 320, the rotating member is disposed in the installation hole, and the rotating member can rotate in the installation hole, so that the fifth rotating portion 511 is rotatably connected to the second cover 320.

[0110] The way in which the sixth rotating part 513 is rotatably connected to the adapter body 100 is introduced in detail as follows. In this embodiment, mounting holes are provided on the sixth rotating part 513. Correspondingly, mounting holes are provided on the adapter body 100. A connecting rotating member (such as a pin shaft) is inserted into the mounting holes on the sixth rotating part 513 and the mounting holes on the adapter body 100, so that the sixth rotating part 513 is rotatably connected to the adapter body 100. Correspondingly, the way in which the sixth rotating part 513 is rotatably connected to the adapter body 100 can also be other ways. For example, a rotating member is provided on the sixth rotating part 513, a mounting hole is provided 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 part 513 is rotatably connected to the adapter body 100. Or, a mounting hole is provided on the sixth rotating part 513, a rotating member is provided 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 part 513 is rotatably connected to the adapter body 100.

[0111] Further, in this embodiment, the adapter body 100 also 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 face 161, and the first surface 162 and the second surface 163 are arranged opposite to each other. The first surface 162 is adjacent to the first cover 310, and the second surface 163 is adjacent to the second cover 320. The seventh rotating part 521 is rotatably connected to the second cover 320, and the eighth rotating part 523 is rotatably connected to the adapter body 100; the connection points of the sixth rotating part 513 and the adapter body 100, and the connection points of the eighth rotating part 523 and the adapter body 100 are all away from the second surface 163.

[0112] When both the first cover 310 and the second cover 320 are in the closed state, the first surface 162 and the second surface 163 both form part of the appearance surface of the power adapter 10. When both the first cover 310 and the second cover 320 are in the open state, at least part of the first surface 162 is blocked by the first cover 310, and at least part of the second surface 163 is blocked by the second cover 320.

[0113] In this embodiment, the way the seventh rotating part 521 is rotatably connected to the second cover body 320 is the same as the way the fifth rotating part 511 is rotatably connected to the second cover body 320. In this embodiment, the seventh rotating part 521 is provided with a mounting hole. Correspondingly, the second cover body 320 is provided with a mounting hole. A connecting rotating member is inserted into the mounting hole on the seventh rotating part 521 and the mounting hole of the second cover body 320 so that the seventh rotating part 521 is rotatably connected to the second cover body 320. The way the seventh rotating part 521 is rotatably connected to the second cover body 320 can also be other ways. For example, a rotating member is provided on the seventh rotating part 521, a mounting hole is provided on the second cover body 320, the rotating member is arranged in the mounting hole, and the rotating member can rotate in the mounting hole so that the seventh rotating part 521 is rotatably connected to the second cover body 320. Or, a mounting hole is provided on the seventh rotating part 521, a rotating member is provided on the second cover body 320, the rotating member is arranged in the mounting hole, and the rotating member can rotate in the mounting hole so that the seventh rotating part 521 is rotatably connected to the second cover body 320. It can be understood that in other embodiments, the way the seventh rotating part 521 is rotatably connected to the second cover body 320 is different from the way the fifth rotating part 511 is rotatably connected to the second cover body 320.

[0114] In this embodiment, the manner in which the eighth rotating portion 523 is rotatably connected to the adapter body 100 is the same as the manner in which the sixth rotating portion 513 is rotatably connected to the adapter body 100. In this embodiment, an installation hole is provided on the eighth rotating portion 523. Correspondingly, an installation hole is provided on the adapter body 100. A connecting rotating member (such as a pin shaft) is inserted into the installation hole on the eighth rotating portion 523 and the installation hole on the adapter body 100, so that the eighth rotating portion 523 is rotatably connected to the adapter body 100. Correspondingly, the manner in which the eighth rotating portion 523 is rotatably connected to the adapter body 100 can also be other manners. For example, a rotating member is provided on the eighth rotating portion 523, an installation hole is provided on the adapter body 100, the rotating member is disposed in the installation hole, and the rotating member can rotate in the installation hole, so that the eighth rotating portion 523 is rotatably connected to the adapter body 100. Or, an installation hole is provided on the eighth rotating portion 523, a rotating member is provided on the adapter body 100, the rotating member is disposed in the installation hole, and the rotating member can rotate in the installation hole, so that the eighth rotating portion 523 is rotatably connected to the adapter body 100. It can be understood that in other embodiments, the manner in which the eighth rotating portion 523 is rotatably connected to the adapter body 100 is different from the manner in which the sixth rotating portion 513 is rotatably connected to the adapter body 100.

[0115] The connection point between the sixth rotating portion 513 and the adapter body 100 and the connection point between the eighth rotating portion 523 and the adapter body 100 both face away from the second surface 163, which can save the thickness space dimension of the adapter body 100 and make the power adapter 10 thinner.

[0116] In the schematic diagram of this embodiment, the second sliding assembly 500 is exemplified by including a third connecting member 510 and a fourth connecting member 520. It can be understood that in other embodiments, the second sliding assembly 500 includes the third connecting member 510 but does not include the fourth connecting member 520. When the second sliding assembly 500 includes both the third connecting member 510 and the fourth connecting member 520, the second cover 320 can be stably connected to the adapter body 100, and further, when the second cover 320 moves relative to the adapter body 100, it is relatively stable and not prone to shaking.

[0117] The connection points of the second rotating part 413 and the adapter body 100, and the connection points of the fourth rotating part 423 and the adapter body 100 both face away from the first surface 162; and the connection points of the sixth rotating part 513 and the adapter body 100, and the connection points of the eighth rotating part 523 and the adapter body 100 both face away from the second surface 163, so that the first sliding assembly 400 and the second sliding assembly 500 are staggered (please refer to Figure 17 and Figure 18 ), which is conducive to saving the space of the power adapter 10 and miniaturizing the power adapter 10.

[0118] In this embodiment, the fifth rotating part 511 of the third connecting piece 510 is fixed to the second cover body 320 by a pin shaft, and the sixth rotating part 513 of the third connecting piece 510 is fixed to the adapter body 100 by a pin shaft; and the seventh rotating part 521 of the fourth connecting piece 520 is fixed to the second cover body 320 by a pin shaft, and the eighth rotating part 523 is fixed to the adapter body 100 by a pin shaft as an example for illustration. In this embodiment, the adapter body 100, the third connecting piece 510, the fourth connecting piece 520 and the second cover form another four-bar mechanism. Among them, the adapter body 100 serves as the frame of the four-bar mechanism, the third connecting piece 510 and the fourth connecting piece 520 serve as the connecting rods of the four-bar mechanism, and the second cover body 320 serves as the connecting rod assembly of the four-bar structure.

[0119] Please refer to Figures 19 to 21 , Figure 19 is Figure 15 a schematic diagram of each connection point in the power adapter shown; Figure 20 is Figure 16 a schematic diagram of each connection point in the power adapter shown; Figure 21 is Figure 17Schematic diagram of each connection point in the power adapter shown. The center of the rotating connection member connecting the fifth rotating portion 511 and the second cover 320 is the fifth connection point P5, the center of the rotating connection member connecting the sixth rotating portion and the adapter body 100 is the sixth connection point P6, the center of the rotating connection member connecting the seventh rotating portion 521 and the second cover 320 is the seventh connection point P7, and the center of the rotating connection member connecting the eighth rotating portion 523 and the adapter body 100 is the eighth connection point P8. Among them, the line connecting the fifth connection point P5 and the seventh connection point P7 is parallel to the line L4 connecting the sixth connection point P6 and the eighth connection point P8, so that when the second cover 320 slides relative to the adapter body 100, the link assembly composed of the second cover 320, the third connection member 510, the fourth connection member 520, and the adapter body 100 is always in translational motion. When the second cover 320 moves relative to the adapter body 100, it is relatively stable, not easy to shake, and not easy to deflect and swing.

[0120] In addition, due to the interaction between the first magnetic member 600 and the second magnetic member 700, when the first cover 310 moves, it drives the second cover 320 to move, or when the second cover 320 moves, it drives the first cover 310 to move. Since the link assembly (the first link assembly) composed of the first cover 310, the first connection member 410, the second connection member 420, and the adapter body 100 is always in translational motion during movement, and the link assembly (the second link assembly) composed of the second cover 320, the third connection member 510, the fourth connection member 520, and the adapter body 100 is always in translational motion during movement, therefore, when the first link assembly and the second link assembly move, the first link assembly and the second link assembly always move in parallel.

[0121] In addition, the connection points of the second rotating portion 413 and the adapter body 100, and the connection points of the fourth rotating portion 423 and the adapter body 100 both face away from the first surface 162; and the connection points of the sixth rotating portion 513 and the adapter body 100, and the connection points of the eighth rotating portion 523 and the adapter 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 an interleaved manner, which is beneficial to saving the space of the power adapter 10 and making the power adapter 10 miniaturized.

[0122] Specifically, the adapter body 100 serves as the frame of the first link assembly and the second link assembly. That is, the line connecting the center of the rotating connection member connecting the second rotating portion 413 and the adapter body 100 and the center of the rotating connection member connecting the fourth rotating portion 423 and the adapter body 100 serves as a frame, and the frame is located at the lower part of the adapter body 100, and this frame is called the first frame. When the first cover 310 slides, the first cover 310 moves around the first frame.

[0123] Similarly, the line connecting the midline of the rotating connection member connecting the sixth rotating portion 513 to the adapter body 100 and the center of the rotating connection member connecting the eighth rotating portion 523 and the adapter body 100 serves as a frame, and the frame is located at the upper part of the adapter body 100, and this frame is called the second frame. When the second cover 320 slides, the second cover 320 moves around the second frame.

[0124] It can be seen that the first sliding member and the second sliding member are arranged in a cross pattern, thus forming a cross arrangement structure of "the upper controls the lower, and the lower controls the upper", where the first frame located above controls the second cover 320 located below, and the second frame located below controls the first cover 310 located above.

[0125] Please refer to Figure 22 , Figure 22 as Figure 2 the schematic structural diagram of the power adapter shown in the semi-open state. The first cover 310 further includes a first mating surface 312 facing away from the first sub-end surface 311, and the second cover 320 further includes a second mating surface 322 facing away from the second sub-end surface 321. Correspondingly, the adapter body 100 further includes a side wall 112 connected between the first surface 162 and the second surface 163. The side wall 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 that are bent and connected. The first connecting surface 1122 and the second connecting surface 1123 are respectively connected to the side surface 1121, and the first connecting surface 1122 and the second connecting surface 1123 face the plug 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.

[0126] The connection between the first connecting surface 1122 and the second connecting surface 1123 is an arc surface. Both the first connecting surface 1122 and the second connecting surface 1123 are inclined surfaces. Correspondingly, both the first mating surface 312 and the second mating surface 322 are inclined surfaces, so that when the first cover body 310 and the second cover body 320 slide relative to the adapter body 100, the adapter body 100 is prevented from blocking the first cover body 310 and the second cover body 320. That is, the first connecting surface 1122 provides an avoidance position for the first mating surface 312, and the second connecting surface 1123 provides an avoidance position for the second mating surface 322, making the sliding of the first cover body 310 and the second cover body 320 smoother.

[0127] Please refer to Figure 22 , operation parts 318 are further provided on the surfaces of the first cover body 310 and the second cover body 320. The operation parts 318 facilitate the user to operate the first cover body 310 and the second cover body 320. In this embodiment, the operation parts 318 are convex structures. In other embodiments, the operation parts 318 can be a plurality of grooves formed on the surfaces of the first cover body 310 and the second cover body 320, or rough structures. It can be understood that in other embodiments, the operation parts 318 are provided on one of the first cover body 310 and the second cover body 320.

[0128] It can be understood that in other embodiments, the operation parts 318 are not provided on the surfaces of the first cover body 310 and the second cover body 320. When the user needs to use the power adapter 10, only a thrust needs to be applied to any one of the first sub-end face 311 of the first cover body 310 and the second sub-end face 321 of the second cover body 320.

[0129] Please refer to Figure 23 , Figure 23 This is Figure 2 a schematic diagram of another angle of the power adapter shown in this application. The power adapter 10 further includes a discharge interface 800. The discharge interface 800 is electrically connected to the circuit board 120 (refer to Figure 24 ) and is used to output the second voltage converted by the circuit board 120. The discharge interface 800 can be, but is not limited to, a Universal Serial Bus (USB) interface. When the discharge interface 800 is a USB interface, the USB interface can be, but is not limited to, a USB 2.0 interface, or a USB 3.0 interface, etc.

Please refer to Figure 24 , Figure 24 which is Figure 2 the exploded schematic view of the power adapter shown in. In this embodiment, the number of the first sliding components 400 is two, the number of the second sliding components 500 is two, and each rotating connecting member is a pin shaft as an example for illustration. In this embodiment, the adapter body 100 includes a housing 110, a circuit board 120, a carrier 130, a first end cap 140, and a second end cap 150. The housing 110 includes an accommodation space 111 for accommodating the circuit board 120. The carrier 130 is used for carrying the plug 200, and the carrier 130 is disposed at the opening of the accommodation space 111. The first end cap 140 and the second end cap 150 are respectively disposed on opposite sides of the carrier 130 and cooperate with the housing 110 to encapsulate the carrier 130. The surface of the first end cap 140 facing away from the housing 110 is the first connection surface 1122 and the second connection surface 1123 described above. Correspondingly, the surface of the second end cap 150 facing away from the housing 110 is the first connection surface 1122 and the second connection surface 1123 described above. It can be understood that the adapter body 100 described above includes two opposite side walls 112, one of the side walls 112 includes the first end cap 140 and the part of the housing 110 connected to the first end cap 140; the other side wall includes the second end cap 150 and the part of the housing 110 connected to the second end cap 150.

[0131] The first cover 310 includes a first cover portion 316 and a first capping portion 317. The surface of the first cover portion 316 constitutes a part of the appearance surface of the power adapter 10. The first cover portion 316 is used to house the first magnetic member 600, and the first capping portion 317 cooperates with the first cover portion 316 to encapsulate the first magnetic member 600. The second cover 320 includes a second cover portion 326 and the second capping portion 327.

The second cover portion 326 is used to house the second magnetic member 700, and the second capping portion 327 cooperates with the second cover portion 326 to encapsulate the second magnetic member 700. When both the first cover 310 and the second cover 320 are in the closed state, the first capping portion 317 faces the second capping portion 327, the first cover portion 316 deviates from the second cover 320 relative to the first capping portion 317, and the second cover portion 326 deviates from the second cover 320 relative to the second capping portion 327.

[0132] The first magnetic member 600 and the first capping portion 317 are also assembled on the first cover portion 316. The second magnetic member 700 and the second capping portion 327 are also assembled on the second cover 320.
