[0052] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0053] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0054] This application describes a power adapter. A power adapter, also called an external power supply, is a power supply voltage conversion device for small portable electronic devices and electronic appliances. The working principle of a power adapter is to convert AC input into DC output. It can be divided into wall-mounted and desktop types according to the connection method.

[0055] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0056] The electronic devices involved in this application may include but are not limited to mobile phones, tablet computers, wearable devices (such as watches, bracelets, augmented reality glasses, virtual reality glasses, etc.), smart home appliances (such as desk lamps, fans, light strips, etc.), other audio products (such as speakers, story machines, headphones, etc.), security cameras, set-top boxes, routers and massagers.

[0057] In one embodiment, the power adapter includes a first shell, a second shell, a conductive member, an ejection mechanism, and a first connector. The first shell is connected to the second shell and forms a receiving cavity. The first shell and the second shell are configured to be relatively concentrically rotatable. The conductive member is mounted on the first shell and is located in the receiving cavity. The ejection mechanism is fixedly connected to the first shell. The first connector is fixedly connected to the ejection mechanism. The ejection mechanism pushes and pulls the first connector in response to the relative rotation of the first shell and the second shell, so that the first connector extends out of the receiving cavity and can be extended to a position electrically connected to the conductive member, or the first connector is retracted into the receiving cavity and can be retracted to a position separated from the conductive member.

[0058] In one embodiment, the conductive member includes an abutment member. The abutment member is disposed in the receiving cavity. The first connector moves relative to the first housing in response to extending out of the receiving cavity and can move to a position abutting against the abutment member, and the abutment member is configured to abut against the first connector under elastic deformation.

[0059] In one embodiment, the power adapter further comprises a printed circuit board and a second connector. The printed circuit board is disposed in the receiving cavity and is electrically connected to the conductive member. The second connector is disposed on the first housing and is electrically connected to the printed circuit board.

[0060] In one embodiment, the power adapter includes a first housing, a second housing, a conductive member, and a first connector. The first housing and the second housing are configured to be relatively rotatable concentrically. The conductive member is installed in the second housing. The first connector is configured to extend out of the second housing and extend to a position abutting against the conductive member in response to the relative rotation of the first housing and the second housing, or to retract into the second housing and retract to a position separated from the conductive member.

[0061] In one embodiment, the first connector includes a mounting seat disposed in the second housing and a plug pin disposed on the mounting seat, wherein the plug pin is used to abut against the conductive member.

[0062] In one embodiment, the power adapter includes a first housing, a second housing, an electronic component, an ejection mechanism, a first connector, and a second connector.

[0063] The first shell is provided with a first accommodating cavity. The second shell is provided with a second accommodating cavity connected to the first shell. The first shell and the second shell are configured to be relatively coaxially rotatable.

[0064] The electronic component includes a printed circuit board and a conductive member. The printed circuit board is arranged in the first accommodating cavity. The conductive member is arranged in the second accommodating cavity and is electrically connected to the printed circuit board. The ejection mechanism is arranged in the second accommodating cavity and is fixedly connected to the first housing.

[0065] The first connector is mounted on the ejection mechanism. The ejection mechanism is configured to push and pull the first connector in response to the relative rotation of the first housing and the second housing, so that the first connector extends out of the second accommodating cavity and can be extended to a position electrically connected to the conductive member, or the first connector is retracted into the second accommodating cavity and can be retracted to a position separated from the conductive member.

[0066] The second connector is disposed on the first housing and is electrically connected to the printed circuit board.

[0067] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A schematic diagram of the structure of a power adapter in one embodiment of the present application is disclosed. Figure 2 Disclose this application Figure 1 A schematic diagram of the structure of the power adapter in another perspective of the embodiment shown, Figure 3 Disclose this application Figure 1 An exploded view of the power adapter in the embodiment shown, Figure 4 Disclose this application Figure 1 In the embodiment shown, the power adapter is along Figure 1 The power adapter 100 may include a first housing 10, a second housing 20 that can be engaged with the first housing 10, an electronic component 30 disposed in the first housing 10 and the second housing 20, a second connector 40 disposed in the first housing 10, a first connector 50 that can be extended or retracted into the second housing 20, and an ejection mechanism 60 housed in the first housing 10 and the second housing 20 and used to drive the first connector 50 to extend or retract into the second housing 20.

[0068] Among them, the first shell 10 and the second shell 20 can be used as a shell after being engaged with each other, and a receiving cavity 101 is set in the shell. The receiving cavity 101 is used to receive and protect the components in the power adapter 100 (such as a printed circuit board and a transformer, inductor, capacitor, control integrated circuit, etc. on the printed circuit board). The first shell 10 can rotate around an axis relative to the second shell 20, and the second shell 20 can also rotate around the same axis relative to the first shell 10. The electronic component 30 is arranged in the receiving cavity 101 for realizing current and voltage conversion. For example, the electronic component 30 is used to realize the conversion of AC input into DC output. The second connector 40 and the first connector 50 are electrically connected to the electronic component 30 respectively. The first connector 50 is at least partially located in the receiving cavity 101 or outside the receiving cavity 101 in response to the relative rotation of the first shell 10 and the second shell 20. One of the second connector 40 and the first connector 50 is used to connect to an AC power source (such as 110-220VAC), so that the power adapter 100 can receive AC power from the AC power source. The other one of the second connector 40 and the first connector 50 is used to connect the electronic device, so that the power adapter 100 can output direct current (eg, 5-24 VDC) to the electronic device as a direct current power source.

[0069] It is understandable that the second connector 40 may also be arranged in the same manner as the first connector 50 , so that the second connector 40 is at least partially located inside or outside the receiving cavity 101 in response to the relative rotation of the first shell 10 and the second shell 20 .

[0070] In addition, the number of connectors such as the second connector 40 and the first connector 50 can be one. For example, the second connector 40 can be omitted. The electronic component 30 is connected to the AC power source (such as 110-220VAC) through the first connector 50, so that the power adapter 100 can receive AC power from the AC power source. The electronic component 30 is not connected to the electronic device through the second connector 40, but is directly connected to the electronic device, that is, the power adapter 100 can be used as a part of the electronic device.

[0071] Furthermore, the number of connectors, such as the second connector 40 and the first connector 50 , may be at least two. For example, if there are two second connectors 40 , two electronic devices may be connected via the second connectors 40 .

[0072] It should be noted that the terms "first", "second", "third", etc. in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", "third", etc. may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0073] It is understandable that the names such as “first shell”, “second shell” and “shell” can be interchanged with each other, for example, the “first shell” can also be called the “second shell”.

[0074] The names “first connector”, “second connector” and “connector” can be interchanged with each other. For example, the “first connector” can also be called the “second connector”.

[0075] Specifically, see Figure 5 , Figure 6 and Figure 7 , Figure 5 Disclose this application Figure 3 The schematic structural diagram of the first housing 10 in the embodiment shown, Figure 6 Disclose this application Figure 5 The schematic structural diagram of the first housing 10 from another perspective is shown. Figure 7 Disclose this application Figure 5 1 is a cross-sectional view of the first housing 10 shown. The first housing 10 can be made of any suitable material, such as plastic, rubber, ceramic, silicon, etc. Although the first housing 10 is shown as having a cylindrical shape, this is not required. The first housing 10 can have any other shape required for a specific application. For example, the first housing 10 can be one of a rectangular shape, a spherical shape, an irregular shape, etc.

[0076] The first housing 10 may include a first bottom plate 11 and a first side plate 12. The first side plate 12 is disposed around the first bottom plate 11 and connected to the first bottom plate 11 to form a first housing 10 having a first accommodating cavity 13 therein. The first accommodating cavity 13 facilitates the first housing 10 to accommodate components in the power adapter 100, such as part or all of the electronic assembly 30 and the second connector 40. Of course, the first accommodating cavity 13 of the first housing 10 may only accommodate part of the second connector 40. In some embodiments, the first accommodating cavity 13 may be a part of the accommodating cavity 101. Of course, in some embodiments, the first accommodating cavity 13 may also be the entire accommodating cavity 101.

[0077] The first bottom plate 11 is a circular plate-like structure, and it can also be other shapes such as rectangular, polygonal, irregular shapes, etc., and the shape can be changed according to actual conditions. The first bottom plate 11 can be provided with a through hole 111 that penetrates the first bottom plate 11. The through hole 111 is connected to the first accommodating cavity 13, so that the second connector 40 is arranged at the through hole 111. In some embodiments, the setting of the through hole 111 can facilitate the second connector 40 to extend out of the first accommodating cavity 13 from the through hole 111.

[0078] It is understandable that the number of the perforations 111 may be at least one. Of course, the number of the perforations 111 may be determined specifically according to the number of the second connectors 40 and the requirements of a specific application. In addition, in some embodiments, the perforations 111 may also be omitted. Even in some embodiments, the perforations 111 may be replaced by grooves. For example, a groove is provided on the first base plate 11 to accommodate the second connector 40, so that the second connector 40 is located outside the first accommodating cavity 13.

[0079] The first side plate 12 can be a cylindrical tubular structure, or other shapes. The shape can be changed according to actual conditions, which will not be described in detail. The first side plate 12 extends from the edge of the first bottom plate 11 to one side and forms a first opening 14. The first side plate 12 can be engaged with the second housing 20 at the first opening 14.

[0080] The first side plate 12 and the first bottom plate 11 may be an integral structure. In one embodiment, the first side plate 12 may be fixed to the first bottom plate 11 by adhesive bonding to form the first shell 10. In one embodiment, the first side plate 12 may also be fixed to the first bottom plate 11 by threaded connection or snap-on connection to form the first shell 10, so as to facilitate the detachable connection between the first bottom plate 11 and the first side plate 12. It can be understood that when the first side plate 12 is connected to the first bottom plate 11 to form the first shell 10, a through hole 111 may also be provided on the first side plate 12. That is, the through hole 111 may be provided on the first bottom plate 11 and / or the first side plate 12.

[0081] See also Figure 5 , Figure 6 and Figure 7 , the first housing 10, for example, the first side plate 12, is provided with a first snap-fit ​​structure 121 at the first opening 14, so as to facilitate the snap-fit ​​connection between the first housing 10 and the second housing 20. The first snap-fit ​​structure 121 may include a connecting plate 1211 extending from the edge of the first side plate 12 at the first opening 14 to one side. A groove 1213 is provided on the connecting plate 1211, so that the corresponding part of the structure of the second housing 20 is stuck in the groove 1213, so as to realize the snap-fit ​​connection between the first housing 10 and the second housing 20. In some embodiments, the first snap-fit ​​structure 121 may also be at least one of a protrusion, a hook, a slot, etc., provided on the first side plate 12.

[0082] The connecting plate 1211 may be an annular structure. The groove 1213 may also be an annular structure. The groove 1213 is arranged on the outer side of the connecting plate 1211, so that the second housing 20 is sleeved on the connecting plate 1211 and is stuck in the groove 1213, so that the second housing 20 rotates relative to the first housing 10 with the groove 1213 as an annular track. Of course, the groove 1213 may also be arranged on the inner side of the connecting plate 1211. It can be understood that the number of grooves 1213 may also be multiple, and multiple grooves 1213 are arranged side by side on the connecting plate 1211. In addition, the groove 1213 may also be discontinuous.

[0083] The first buckle structure 121 can facilitate the first housing 10 to be snap-connected with the second housing 20, and can also facilitate a part of the structure on the second housing 20 to be placed in the groove 1213 and slide in the groove 1213. When the first housing 10, such as the first buckle structure 121, is connected with the second housing 20, the second housing 20 can be rotated around an axis relative to the first housing 10 under force.

[0084] In one embodiment, a plurality of notches 1215 may be provided on the connecting plate 1211 so as to divide the connecting plate 1211 into a plurality of parts. Figure 6 , two notches 1215 are provided on the connecting plate 1211. The connecting plate 1211 is divided into two. It can be understood that the notches 1215 are provided so that each connecting plate 1211 forms a first buckle structure 121. That is, there may be multiple first buckle structures 121 on the first side plate 12. In one embodiment, some connecting plates 1211 may not be provided with grooves 1213.

[0085] It can be understood that the arrangement of the notch 1215 on the connecting plate 1211 can allow the first buckle structure 121 to have a deformation space at the notch 1215, and can allow each connecting plate 1211 to have the ability to elastically deform. During the snap connection process between the first shell 10 and the second shell 20, the connecting plate 1211 undergoes elastic deformation to avoid partial structure of the second shell 20, thereby avoiding damage to the first shell 10 and / or the second shell 20 during installation and removal.

[0086] See also Figure 5 , Figure 6 and Figure 7 , the first housing 10, for example, a mounting member 122 is further provided on the connecting plate 1211. The mounting member 122 is used to mount and fix some components of the electronic assembly 30. The number of the mounting members 122 can be two, namely, a first mounting member 1221 and a second mounting member 1223. Of course, the number of the mounting members 122 can be adjusted according to actual needs. For example, the number of the mounting members 122 can be not only two, but also one or three.

[0087] The first mounting member 1221 and the second mounting member 1223 may both be plate-shaped structures. The first mounting member 1221 and the second mounting member 1223 are respectively extended to one side from the edge of the first buckle structure 121, such as the connecting plate 1211. The first mounting member 1221 and the second mounting member 1223 may be symmetrically arranged.

[0088] It can be understood that the mounting member 122 is disposed on the first buckle structure 121, such as the connecting plate 1211, and the mounting member 122 can be an integral structure with the first buckle structure 121. The first buckle structure 121 can fix the electronic component 30. In one embodiment, the mounting member 122 can also be directly disposed on the first side plate 12. For example, the mounting member 122 extends to one side from the edge of the first side plate 12 at the first opening 14. In some embodiments, the mounting member 122 can also be disposed on the ejection mechanism 60. In some embodiments, the mounting member 122 can also be omitted.

[0089] See also Figure 8 and Fig. 9 , Figure 8 Disclose this application Figure 3 The schematic diagram of the structure of the second housing 20 in the embodiment shown, Fig. 9 Disclose this application Figure 8 20 is a partial cross-sectional view of the second housing 20 shown. The second housing 20 can be made of any suitable material, such as plastic, rubber, ceramic, silicon, etc. Although the second housing 20 is shown as having a cylindrical shape, this is not required. The second housing 20 can have any other shape required for a particular application. For example, the second housing 20 can be one of a rectangular shape, a spherical shape, an irregular shape, etc.

[0090] The second housing 20 may include a second bottom plate 21 and a second side plate 22. The second side plate 22 is arranged around the second bottom plate 21 and connected to the second bottom plate 21 to form a second housing 20 having a second accommodating cavity 23. The second side plate 22 is arranged on a side opposite to the second bottom plate 21 to form a second opening 24 so as to be snap-connected with the first housing 10, such as the first snap-fit ​​structure 121, at the second opening 24. The second accommodating cavity 23 is convenient for accommodating components in the power adapter 100, such as some components of the electronic assembly 30 and the first connector 50. The second housing 20 can be snap-connected with the first housing 10 to form an accommodating cavity 101. That is, the second accommodating cavity 23 can be a part of the accommodating cavity 101. In some embodiments, the second accommodating cavity 23 can also be the entire accommodating cavity 101.

[0091] The second bottom plate 21 is a circular plate-like structure, and it can also be other shapes such as rectangular, polygonal, irregular shapes, etc., and the shape can be changed according to actual conditions. The second bottom plate 21 can be provided with a channel 211 such as a first channel 2111 and a second channel 2113 that penetrates the second bottom plate 21. The channel 211 such as the first channel 2111 and the second channel 2113 are connected to the second accommodating cavity 23, so that the first connector 50 can extend or retract into the second accommodating cavity 23 through the channel 211 such as the first channel 2111 and the second channel 2113.

[0092] It is understandable that the number of channels 211 may be one or more, which may be determined according to the number of first connectors 50 and the requirements of a specific application. In some embodiments, the first channel 2111 or the second channel 2113 may be omitted. In some embodiments, the channel 211 may also be omitted.

[0093] The second bottom plate 21 is provided with a protrusion 212. The protrusion 212 is used to connect with the ejection mechanism 60, and plays a role in stabilizing the ejection mechanism 60.

[0094] Of course, in some embodiments, the protrusion 212 can be omitted. In some embodiments, the protrusion 212 can also be replaced by a groove or a through hole, that is, the second bottom plate 21 can be provided with a groove or a through hole so that the ejection mechanism 60 can extend into the groove or the through hole to achieve the connection between the second bottom plate 21 and the ejection mechanism 60 and stabilize the ejection mechanism 60.

[0095] The second side plate 22 can be a circular tubular structure, or other shapes. The design can be made according to the actual situation, and no further details are given. The second side plate 22 can be extended from the edge of the second bottom plate 21 to one side, and a second opening 24 is formed. The second side plate 22 can be connected to the first shell 10, such as the first snap structure 121, at the second opening 24. The second side plate 22 and the second bottom plate 21 can be an integral structure. In one embodiment, the second side plate 22 and the second bottom plate 21 can be fixed to form the second shell 20 by adhesive bonding. In one embodiment, the second side plate 22 and the second bottom plate 21 can also be fixed to form the second shell 20 by threaded connection or snap connection, so as to facilitate the detachable connection between the second bottom plate 21 and the second side plate 22. It can be understood that when the second side plate 22 is connected to the second bottom plate 21 to form the second shell 20, a channel 211, such as a first channel 2111 and a second channel 2113, can also be provided on the second side plate 22. That is, the channel 211 may be provided on the second bottom plate 21 and / or the second side plate 22 .

In one embodiment, the number of the guide members 222 may be at least one, for example, one of the first guide member 2221 or the second guide member 2223 may be omitted.

[0098] It can be understood that the guide member 222, such as the first guide member 2221 and the second guide member 2223, is disposed in the second accommodating cavity 23, so the guide member 222, such as the first guide member 2221 and the second guide member 2223, can also be formed on the second bottom plate 21, instead of being disposed on the second side plate 22. In addition, the guide member 222, such as the first guide member 2221 and the second guide member 2223, can be disposed on the second bottom plate 21 and the second side plate 22.

When the first housing 10 and the second housing 20 are engaged and connected, the first buckle structure 121 and the second buckle structure 223 are buckled and connected. Specifically, the second buckle structure 223 is sleeved on the outside of the first buckle structure 121, and the second buckle structure 223 is placed in the groove 1213 on the connecting plate 1211, and can slide in the groove 1213, so that the first housing 10 can rotate relative to the second housing 20 around an axis.

[0102] It is understandable that the names such as “first snap-fit ​​structure”, “second snap-fit ​​structure” and “snap-fit ​​structure” can be interchanged with each other, for example, the “first snap-fit ​​structure” can also be called the “second snap-fit ​​structure”.

[0137] See also Fig.18 The ejection member 15, such as the push-pull rod 151, responds to the rotation of the first shell 10 relative to the second shell 20, and pushes the first connector 50, such as the mounting seat 52, so that the first connector 50, such as the mounting seat 52, slides along the axial direction of the push-pull rod 151, so that the conductive member 51 extends out of the second accommodating cavity 23, and when the conductive member 51, such as the first pin 511 and the second pin 512 extend out of the second accommodating cavity 23, the first pin 511 abuts against the abutment member 323 of the electronic component 30, such as the first conductive member 32a, and the second pin 512 abuts against the abutment member 323 of the electronic component 30, such as the second conductive member 32b.

[0138] It can be understood that the push-pull rod 151 can also be a rod-shaped structure with a gear or a gear assembly installed. The push-pull rod 151 is connected by meshing with the mounting seat 52. The axial direction of the push-pull rod 151 may not be parallel to the extension direction of the guide member 222. In one embodiment, the mounting seat 52 is provided with a rack meshing with the gear in the gear assembly, and the meshing connection between the mounting seat 52 and the push-pull rod 151 is achieved through the rack and the gear assembly. The rack and the gear assembly are provided within the scope that can be understood by those skilled in the art, and no further description is given.

[0139] It can be understood that the push-pull rod 151 drives the mounting seat 52 to realize the movement of the first connector 50, and the guide member 222, such as the first guide member 2221 and the second guide member 2223, is used to guide the mounting seat 52. It can be understood that the ejection mechanism 60 can omit the mounting seat 52, and the guide member 222, such as the first guide member 2221 and the second guide member 2223, can serve as a part of the ejection mechanism 60.

[0140] In addition, the channel 211, such as the first channel 2111 and the second channel 2113, can guide the mounting seat 52 in some embodiments. It can be understood that the ejection mechanism 60 can omit the mounting seat 52, and the channel 211, such as the first channel 2111 and the second channel 2113, can be used as a part of the ejection mechanism 60.

[0141] When assembling the power adapter 100, refer to Fig.11 and Fig.13 , the second connector 40 is fixed by welding to the conductive pin of the printed circuit board 31, and the printed circuit board 31 and the second connector 40 are installed in the first accommodating cavity 13, so that the second connector 40 corresponds to the through hole 111, so that the second connector 40 is electrically connected to the electronic device through the through hole 111. The fixing member 321 of the conductive member 32 is fixed to the mounting member 122 by using the first clamping portion 3211, the second clamping portion 3213 and the third clamping portion 3215. The extension member 322 passes through the through hole, such as the first through hole 1521 and the second through hole 1523, and is fixed by welding to the conductive pin of the printed circuit board 31.

[0142] See also Fig.23 , the first connector 50 is mounted on the ejection member 15. The push-pull rod 151 passes through the screw hole 522 of the first connector 50, so that the first connector 50, such as the mounting seat 52, is threadedly connected with the push-pull rod 151.

[0143] See also Figure 4 and Fig.17, the first housing 10 is buckled with the second housing 20, and the first connector 50, such as the pins, is respectively matched with the channels 211, such as the first channel 2111 and the second channel 2113, that is, the first pin 511 can extend from the first channel 2111, and the second pin 512 can extend from the second channel 2113. The first connector 50, such as the slide 521, is matched with the guide member 222, such as the first guide member 2221 and the second guide member 2223, that is, the first guide member 2221 is placed in one slide 521, and the second guide member 2223 is placed in one slide 521, so that the first connector 50 can slide along the extension direction of the guide member 222, and the first connector 50, such as the first pin 511 and the second pin 512, slide out of the second accommodation cavity 23 from the channel 211, such as the first channel 2111 and the second channel 2113. The first buckle structure 121 and the second buckle structure 223 are buckled.

[0144] See also Fig.16 and Fig.17 When in use, hold the first shell 10 and rotate the second shell 20. Due to the setting of the thread, the mounting seat 52 and the push-pull rod 151 make a rotational motion. The guide members 222, such as the first guide member 2221 and the second guide member 2223, cooperate with the mounting seat 52, so that the mounting seat 52 moves in the axial direction of the push-pull rod 151. By changing the rotation direction of the second shell 20, the mounting seat 52 drives the first pin 511 and the second pin 512 to extend out of the second accommodating cavity 23 or retract into the second accommodating cavity 23.

[0145] See also Fig.24 and Fig.25 , respectively disclosed in this application Figure 3 In the cross-sectional view of the power adapter 100 shown in the figure, when the first pin 511 and the second pin 512 are at least partially located outside the second accommodating cavity 23, the abutment 323 abuts against the first pin 511, and the abutment 323 abuts against the second pin 512. When the first pin 511 and the second pin 512 are retracted into the second accommodating cavity 23, the mounting base 52 drives the first pin 511 and the second pin 512 to move toward one side of the first shell 10, so that the abutment 323 is disconnected from the first pin 511, and the abutment 323 is disconnected from the second pin 512.

[0146] The ejection member 15, such as the push-pull rod 151, responds to the rotation of the first shell 10 relative to the second shell 20, and pushes the first connector 50, such as the mounting seat 52, so that the first connector 50, such as the first pin 511 and the second pin 512, slide in the extension direction of the slide 521 to extend out of the second accommodating cavity 23, and when the first connector 50, such as the first pin 511 and the second pin 512 extend out of the second accommodating cavity 23, the first pin 511 abuts against the abutment piece 323 of the electronic component 30, such as the first conductive member 32a, and the second pin 512 abuts against the abutment piece 323 of the electronic component 30, such as the second conductive member 32b.

[0147] The ejection member 15, such as the push-pull rod 151, responds to the rotation of the first shell 10 relative to the second shell 20, pulling the first connector 50, such as the mounting seat 52, so that the first connector 50, such as the first pin 511 and the second pin 512, slide along the extension direction of the slide 521 to retract to the second accommodating cavity 23, and when the first connector 50, such as the first pin 511 and the second pin 512 are retracted to the second accommodating cavity 23, the connection between the first pin 511 and the abutment 323 of the electronic component 30, such as the first conductive member 32a, is disconnected, and the connection between the second pin 512 and the abutment 323 of the electronic component 30, such as the second conductive member 32b, is disconnected.

[0148] See also Figure 1 When the first housing 10 and the second housing 20 rotate relative to each other, the outer surface of the first housing 10 and the outer surface of the second housing 20 are always flush, that is, there is no sharp corner between the contacting parts of the first housing 10 and the second housing 20, which improves the appearance. Therefore, there is no limit on the rotation angle of the first housing 10 and the second housing 20 to rotate relative to each other to achieve the first connector 50 being rotated out or stored.

[0149] In one embodiment, the first housing 10 can rotate 360° relative to the second housing 20, so that the first connector 50 can move from a state of being completely accommodated in the second accommodating cavity 23 to a state of being extended out of the second accommodating cavity 23 to the maximum extent. Of course, the rotation angle can also be 45°, or 90°. The rotation angle can be set according to actual needs and will not be described in detail.

[0150] See also Fig.26 , which discloses the present application Figure 1A schematic diagram of the structure of another appearance change of the power adapter 100 shown. In the power adapter 100, the first shell 10 and the second shell 20 are both columnar structures with square cross-sections. Of course, the first shell 10 and the second shell 20 can also be columnar structures with polygonal cross-sections. Therefore, when the first shell 10 and the second shell 20 rotate relative to each other, corners are generated between the parts where the first shell 10 and the second shell 20 contact each other, affecting the appearance expression. When the first connector 50 is in a state of being completely accommodated in the second accommodating cavity 23, corners are generated between the parts where the first shell 10 and the second shell 20 contact each other, which will affect the storage. When the first connector 50 moves to a state where it extends out of the second accommodating cavity 23 to the maximum extent. Corners are generated between the parts where the first shell 10 and the second shell 20 contact each other, which will affect the use.

[0151] Therefore, it is necessary to limit the rotation angle of the first housing 10 and the second housing 20 to rotate relative to each other to realize the first connector 50 being rotated out or stored, so that when in the two states of storage and use, the outer surface of the first housing 10 and the outer surface of the second housing 20 are flush, and there are no edges and corners between the contact parts of the first housing 10 and the second housing 20, thereby improving the appearance of the power adapter 100. For example, the rotation angle can be an integer multiple of 90°.

[0152] See also Fig.26 , a first receiving groove 123 is provided on the side of the first side plate 12 of the first shell 10 facing the second shell 20. A first magnetic member 124 is provided in the first receiving groove 123. A second receiving groove 224 is provided on the side of the second side plate 22 of the second shell 20 facing the first shell 10. A second magnetic member 225 is provided in the second receiving groove 224. The first magnetic member 124 and the second magnetic member 225 are configured to attract each other with opposite poles. The first shell 10 can be rotated relative to the second shell 20 by an integer multiple of 360°, so that the first connector 50 can be moved from a state of being completely accommodated in the second receiving cavity 23 to a state of being extended out of the second receiving cavity 23 to the greatest extent.

[0153] When the first connector 50 is fully accommodated in the second accommodating cavity 13, the first magnetic member 124 and the second magnetic member 225 are attracted to each other, and the user can easily sense that the first shell 10 and the second shell 20 have been relatively rotated into place. At the same time, the outer surface of the first shell 10 is flush with the outer surface of the second shell 20, and there are no sharp edges between the contact parts of the first shell 10 and the second shell 20, which is convenient for storage.

[0154] When the first connector 50 moves to the state of being extended out of the second accommodating cavity 23 to the maximum extent, the first magnetic member 124 and the second magnetic member 225 face each other and attract each other, so that the user can easily sense that the first shell 10 and the second shell 20 are relatively rotated into place, and at the same time, the outer surface of the first shell 10 and the outer surface of the second shell 20 are flush, and there is no sharp corner between the contacting parts of the first shell 10 and the second shell 20, which is convenient for use.

[0155] It can be understood that the number of the first magnetic member 124 and the second magnetic member 225 can be multiple. The first magnetic member 124 and the second magnetic member 225 can be evenly distributed around the axis of rotation of the first shell 10 relative to the second shell 20. For example, there can be two first magnetic members 124, and when the second magnetic member 225 is directly facing and attracting any one of the two first magnetic members 124, the outer surface of the first shell 10 and the outer surface of the second shell 20 are flush, and there is no edge between the parts where the first shell 10 and the second shell 20 contact each other. When the second magnetic member 225 is directly facing and attracting one of the two first magnetic members 124, the first connector 50 is in a state of being completely accommodated in the second accommodating cavity 23. When the second magnetic member 225 is directly facing and attracting the other of the two first magnetic members 124, the first connector 50 is in a state of moving to the maximum extent to extend out of the second accommodating cavity 23.

[0156] It can be understood that the first magnetic member 124 and the second magnetic member 225 can both be magnets, and the arrangement of the first magnetic member 124 and the second magnetic member 225 can produce a centering effect in place, avoid poor appearance expression, and improve user experience. In addition, in the embodiment where the battery exists, the first magnetic member 124 and the second magnetic member can both be electromagnets.

[0157] The present application adopts a design in which the first housing 10 and the second housing 20 rotate concentrically relative to each other, and the first connector 50 is displaced by adjusting the ejection mechanism 60 through the relative rotation of the first housing 10 and the second housing 20, so that the first connector 50 is at least partially located outside the receiving cavity 101 for normal use, and the first connector 50 is located inside the receiving cavity 101 for storage. The technical solution of the present application is simple and reliable, and can realize the unscrewing, locking and storage of the power adapter, reduce the product size, prevent misoperation, and improve the user experience.
