Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a plug. Background Technology

[0002] With the development of technology, there are more and more types of electronic products, and there are also more and more plugs used for electronic products. By inserting the plug's prongs into the socket, electronic products can be charged.

[0003] However, in related technologies, plugs typically only have a charging function, which is relatively simple and leads to a poor user experience. Utility Model Content

[0004] This application provides a plug with more functions, which can improve the user experience.

[0005] Specifically, a plug includes:

[0006] The housing has a receiving cavity and a clearance opening communicating with the receiving cavity;

[0007] The electronic control components are located within the receiving cavity;

[0008] A display element, disposed on the housing and electrically connected to the electronic control assembly, the display element having a display surface located on the outer side of the housing, the display surface being used to display charging information of the plug; and,

[0009] A pin is inserted through the recessed opening. The pin is electrically connected to the electronic control component and rotatably connected to the housing. The pin has a storage position, a first working position, and a second working position arranged sequentially on its rotation trajectory.

[0010] Specifically, when the pin is in the first working position and the second working position, the portion of the pin extending out of the housing and the display surface are located on different sides of the housing, and when the pin is in the first working position, the extension direction of the pin is perpendicular to the display surface; when the pin is in the second working position, the extension direction of the pin is parallel to the display surface.

[0011] The beneficial effects of this application are as follows: When carrying and storing the plug, the prongs can be rotated to the storage position. In this position, the length of the prongs extending out of the housing is shorter, making the plug smaller and thus more convenient to carry and store. When charging the plug, the prongs can be rotated to the first or second working position. In this position, the length of the prongs extending out of the housing is longer, making it easier to insert the prongs into the socket. Furthermore, the prongs have two different working positions. When the prongs are in different working positions, the extension direction of the prongs is different, resulting in different angles between the prongs and the housing. Users can adjust the position of the prongs according to different usage scenarios, allowing for flexible adjustment of the angle between the prongs and the housing when encountering different types of sockets. This makes it easier for the prongs to be inserted into the socket, preventing problems such as unstable insertion, obstruction of adjacent sockets, and interference with other plugs, thus meeting the needs of users in different usage scenarios. Furthermore, on the one hand, users can obtain the charging status and device information of their electrical equipment in real time through the display surface, enabling them to clearly understand the entire charging process, enhancing their trust in the plug, alleviating charging anxiety, and thus improving the plug's safety and reliability. On the other hand, it also enriches the plug's functionality, further improving the user experience. In addition, in this application, the angle between the display surface and the plug changes when the prongs are in the first and second working positions. This allows users to adjust the prong position according to the orientation of the socket's holes, ensuring that the display surface is always facing a direction easily visible to the user when the prongs are inserted into the socket's holes. This ensures the visibility of the display surface in various usage scenarios, facilitating the user's viewing of the charging information displayed, and further enhancing the user experience.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0037] In related technologies, the prongs of most plugs are usually fixed to the plug housing, making the plugs bulky. This makes them inconvenient to carry and store. Furthermore, in actual use, when the prongs are inserted into the socket holes, they can easily interfere with other devices on the socket, making it difficult to insert the prongs. This fails to meet the needs of users in different usage scenarios and reduces the user experience.

[0038] A small number of plugs have prongs that can rotate, but the prongs can usually only rotate between a retracted state and a working state. When the plug is not in use, the prongs can be rotated to the retracted state to reduce the overall size of the plug. When the plug is in use, the prongs are rotated to the working state. At this time, the prongs are also prone to interference with other devices on the socket, making it difficult to insert the prongs into the socket. Therefore, it cannot meet the needs of users in different usage scenarios and reduces the user experience.

[0039] Furthermore, in related technologies, plugs typically only have a charging function, which is relatively simple and can lead to a poor user experience.

[0040] In view of the above-mentioned technical problems, this application provides a plug to solve the above-mentioned technical problems.

[0041] Specifically, such as Figures 1 to 3 As shown, the plug includes a housing 10 and an electronic control component 20 (such as...). Figure 8 ) and pin 31.

[0042] The housing 10 is provided with a receiving cavity 11 (e.g. Figure 8 The housing 10 includes a recessed opening 12 that communicates with the receiving cavity 11. The overall shape of the housing 10 can be cuboid, cube, cylinder, or other shapes.

[0043] The electronic control component 20 is located within the receiving cavity 11. The electronic control component 20 enables the electrical connection between the plug 31 and the electrical device, allowing the device to connect to a power source via the plug. Furthermore, the electronic control component 20 controls the electronic components within the plug, including the output current and charging power. The electrical device can be a mobile phone, tablet, gaming device, AR (Augmented Reality) device, data storage device, audio playback device, video playback device, desktop computing device, or wearable device. Wearable devices can include electronic watches, electronic glasses, electronic helmets, electronic bracelets, electronic necklaces, etc.

[0044] The pin 31 passes through the recess opening 12, is electrically connected to the electronic control component 20, and is rotatably connected to the housing 10. The rotation trajectory of the pin 31 has sequentially arranged storage positions (e.g., ...). Figure 1 ), first working position (e.g.) Figure 2 ) and second work position (e.g. Figure 3 The clearance opening 12 provides rotation space for the pin 31 and restricts the rotation trajectory of the pin 31, so that the pin 31 rotates according to a preset trajectory. The pin 31 is made of metal material. The head end of the pin 31 is used to insert into the socket, and the tail end of the pin 31 is used to connect to the electrical control component 20, so as to realize the electrical connection between the plug and the electrical equipment through the pin 31.

[0045] It should be noted that the storage position, the first working position, and the second working position are three different positions on the rotation trajectory of the plug 31. The plug 31 can be rotated from the storage position to the first working position or the second working position in a clockwise or counterclockwise direction. The length of the part of the plug 31 extending out of the housing 10 when it is in the storage position is less than the length of the part of the plug 31 extending out of the housing 10 when it is in the first working position and the second working position. This makes the plug smaller in size when the plug 31 is in the storage position. When it is necessary to carry and store the plug, the plug 31 can be rotated to the storage position, making it more convenient to carry and store the plug. When it is necessary to use the plug for charging, the plug 31 can be rotated to the first working position or the second working position. At this time, the length of the part of the plug 31 extending out of the housing 10 is longer, making it easier to plug the plug 31 into the socket hole.

[0046] It should also be noted that in this application, the plug 31 has two different working positions (the first working position and the second working position, respectively). When the plug 31 is in different working positions, the extension direction of the plug 31 is different, which makes the angle formed between the plug 31 and the housing 10 different. Users can adjust the position of the plug 31 according to different usage scenarios, so that when encountering different types of sockets, the angle formed between the plug 31 and the housing 10 can be flexibly adjusted, making it easier for the plug 31 to be inserted into the socket hole, preventing problems such as unstable plugging, blocking of adjacent socket holes, and interference with other plugs around it. This can meet the needs of users in different usage scenarios and is applicable to usage scenarios such as at home, office, and travel, thereby improving the user experience.

[0047] Specifically, such as Figures 4 to 7 As shown, the plug also includes a display element 40, which is disposed in the housing 10 and electrically connected to the electronic control component 20. The display element 40 has a display surface 41 located on the outer side of the housing 10. The display surface 41 is used to display the plug's charging information, including but not limited to the plug's charging power, charging current, charging voltage, charging mode, and the brand and model of the electrical device, its battery capacity, estimated charging time, and battery health status. On the one hand, users can obtain the charging status and device information of the electrical device in real time through the display surface 41, enabling users to clearly understand the entire charging process, enhancing their trust in the plug, alleviating charging anxiety, and thus enhancing the plug's safety and reliability. On the other hand, it can also enrich the plug's functions, thereby further improving the user experience.

[0048] When the pin 31 is in the first working position and the second working position, the part of the pin 31 extending out of the housing 10 and the display surface 41 are located on different sides of the housing 10, so that the pin 31 and the display surface 41 have different orientations. When the pin 31 is inserted into the socket, the pin 31 is located on the side of the housing 10 closer to the socket, but the display surface 41 is not located on the side of the housing 10 closer to the socket, thereby preventing the display surface 41 from being blocked by the socket.

[0049] Furthermore, such as Figure 4 and Figure 5 As shown, when pin 31 is in the first working position, the extension direction of pin 31 is perpendicular to the display surface 41; Figure 6 and Figure 7 As shown, when pin 31 is in the second working position, the extension direction of pin 31 is parallel to the display surface 41.

[0050] It should be noted that when the socket is placed on a vertical wall, the socket is usually oriented perpendicular to the wall, making it horizontal; while when the socket is placed on a horizontal table, the socket is usually oriented perpendicular to the table, making it vertical. In this application, when the pin 31 is between the first and second working positions, the angle between the display surface 41 and the pin 31 also changes. This allows the user to adjust the position of the pin 31 according to the orientation of the socket's socket, ensuring that the display surface 41 is always facing a direction easily visible to the user when the pin 31 is inserted into the socket. This ensures the visibility of the display surface 41 in various usage scenarios, making it easier for the user to view the charging information displayed on the display surface 41, thereby further improving the user experience.

[0051] In some embodiments, the pin 31 can rotate 90 degrees from the storage position to the first working position; of course, in other embodiments, the pin 31 can rotate from the storage position to the first working position by other angles, such as 45 degrees, 60 degrees, or 75 degrees. In some embodiments, the pin 31 can rotate 90 degrees from the first working position to the second working position; of course, in other embodiments, the pin 31 can rotate from the first working position to the second working position by other angles, such as 60 degrees, 75 degrees, or 120 degrees.

[0052] See also Figures 4 to 7 As shown, in some embodiments, the outer surface of the housing 10 includes a first end face 13 and a second end face 14 (e.g., ...). Figure 3 The outer peripheral surface 15 is located between the first end surface 13 and the second end surface 14 and connected to both the first end surface 13 and the second end surface 14. The display surface 41 is located on the side of the housing 10 with the first end surface 13.

[0053] The clearance opening 12 includes a first opening 121 located on the second end face 14 and a second opening 122 located on the outer peripheral face 15. When the pin 31 is in the first working position (e.g. Figure 2 The pin 31 passes through the first opening 121; when the pin 31 is in the second working position (e.g., Figure 3 When ), pin 31 is inserted into the second opening 122.

[0054] It should be noted that the first opening 121 and the second opening 122 are two interconnected parts of the clearance opening 12. When the pin 31 is in the first working position, the pin 31 extends out of the housing 10 from the first opening 121, and the part of the pin 31 outside the housing 10 is positioned opposite to the display surface 41, so that the orientation of the pin 31 is opposite to the orientation of the display surface 41, and the extension direction of the pin 31 is perpendicular to the display surface 41. When the pin 31 is inserted into the socket, the display surface 41 is located on the housing 10 away from the socket. The side allows the user to easily see the display surface 41. When the pin 31 is in the second working position, the pin 31 extends out of the housing 10 from the second opening 122, and the part of the pin 31 outside the housing 10 is adjacent to the display surface 41, so that the orientation of the pin 31 is perpendicular to the orientation of the display surface 41, and the extension direction of the pin 31 is parallel to the display surface 41. When the pin 31 is inserted into the socket, the display surface 41 is located on the side of the housing 10 adjacent to the socket, and the user can also easily see the display surface 41.

[0055] It should also be noted that when the socket is placed on a vertical wall, such as Figure 4 As shown, pin 31 can be rotated to the first working position, so that the display surface 41 faces the side away from the vertical wall; of course, as Figure 6 As shown, at this time, the plug 31 can also be rotated to the second working position, and the display surface 41 can be set upwards, so that the user can more easily see the display screen 42. When the socket is placed on a horizontal table, as... Figure 5 As shown, pin 31 can be rotated to the first working position so that the display surface 41 faces upward; of course, as... Figure 7 As shown, at this time, the pin 31 can also be rotated to the second working position, and the display surface 41 can be oriented toward a side perpendicular to the extension direction of the pin 31.

[0056] Understandably, in this application, users can adjust the position of the plug 31 by adjusting the placement of the socket, thereby adjusting the orientation of the display surface 41. This ensures that the plug can be inserted into the socket hole in a way that is easy for the user to see, thus ensuring the visibility of the display surface 41 in various usage scenarios and further improving the user experience.

[0057] In some embodiments, a plug-in interface 51 is provided on the outer peripheral surface 15. The plug-in interface 51 is electrically connected to the electronic control component 20 and is used for data cable plugging to electrically connect the electronic control component 20 to the data cable. It is understood that by providing the plug-in interface 51 on the outer peripheral surface 15, the plug-in interface 51 can avoid the pin 31 and the display surface 41, and facilitates the user to plug the data cable into the plug-in interface 51.

[0058] The plug-in interface 51 can be provided as a single or multiple locations. These multiple interfaces 51 can be located on the same side of the housing 10 or on different sides. When multiple interfaces 51 are provided, the plug can charge multiple electrical devices simultaneously. The display surface 41 can display the charging power distribution of each electrical device in real time, allowing users to conveniently monitor the charging status of each device while charging multiple devices simultaneously, ensuring an efficient and safe charging process.

[0059] In some embodiments, a button 52 is provided on the outer peripheral surface 15. The button 52 is electrically connected to the display 40, and the display 40 can be controlled to perform corresponding operations by pressing the button 52, such as power on / off operation, mode switching operation, etc. The button 52 can be a push-button button, a touch button, or other type of button. There can be one or more buttons 52.

[0060] It should also be noted that only the plug-in interface 51 can be provided without the button 52; only the button 52 can be provided without the plug-in interface 51; or both the plug-in interface 51 and the button 52 can be provided at the same time, in which case the plug-in interface 51 and the button 52 can be located on the same side or different sides of the outer peripheral surface 15.

[0061] In some embodiments, the outer peripheral surface 15 includes a first side surface 151 disposed opposite to each other (e.g., Figure 4 ) and the second side 152 (e.g.) Figure 3 The second opening 122 includes a first portion 122a located on the first side 151.

[0062] When pin 31 is in the second working position, pin 31 passes through the first part 122a, and the plug interface 51 and / or button 52 are located on the second side 152. At this time, the orientation of pin 31 is opposite to that of plug interface 51 and / or button 52. When the data cable is inserted into plug interface 51, the insertion direction is the same as the extension direction of pin 31, so that the force direction of the plug is consistent with the extension direction of pin 31, which can prevent pin 31 from shaking or falling off when the data cable is inserted into plug interface 51. When button 52 is pressed, the pressing direction is the same as the extension direction of pin 31, so that the force direction of the plug is consistent with the extension direction of pin 31, which can prevent pin 31 from shaking or falling off when the data cable is inserted into plug interface 51.

[0063] In some embodiments, the second opening 122 includes a second portion 122b located on the second side 152, through which the pin 31 passes when the pin 31 is in the retracted position.

[0064] It should also be noted that when pin 31 is in the storage position, the angle formed between the extension direction XX of pin 31 and the second end face 14 can be 45 degrees, 60 degrees, 75 degrees, 90 degrees, 100 degrees, 120 degrees, 135 degrees, 150 degrees, 180 degrees, or other angles. When pin 31 is in the first working position, the angle formed between the extension direction XX of pin 31 and the second end face 14 can be 90 degrees. When pin 31 is in the second working position, the angle formed between the extension direction XX of pin 31 and the second end face 14 can be 0 degrees, that is, the extension direction XX of pin 31 is parallel to the second end face 14.

[0065] like Figure 7 and Figure 8 As shown, in some embodiments, the display 40 includes a display screen 42 and a light-transmitting cover 43. The display screen 42 can be installed on the side of the housing 10 with a first end face 13. The display screen 42 has a display surface 41. The light-transmitting cover 43 is disposed on the side of the housing 10 with the first end face 13 and is connected to the housing 10. The light-transmitting cover 43 can provide protection for the display screen 42 and allow light emitted by the display screen 42 to pass through.

[0066] In some embodiments, the housing 10 may include a middle shell 16 and a front cover 17, which together form a receiving cavity 11. A pin 31 is rotatably connected to the front cover 17, and a clearance opening 12 may be provided in the front cover 17. The electronic control assembly 20 may be located within the middle shell 16. The front cover 17 may be detachably connected to the middle shell 16, allowing the front cover 17 to be removed for maintenance and replacement of components within the receiving cavity 11. Alternatively, the front cover 17 may be fixedly connected to the middle shell 16.

[0067] See Figure 9 and Figure 10As shown, in some embodiments, the electronic control component 20 includes multiple circuit boards and a transformer 24. The circuit board assembly composed of multiple circuit boards is used to convert the AC power connected to the pin 31 into DC power, and at the same time output the relevant charging information to the display screen 42 so that the display screen 42 can display the charging information. The transformer 24 can convert high-voltage DC power into low-voltage DC power and output the low-voltage DC power required by the electrical equipment to the electrical equipment.

[0068] Multiple circuit boards are electrically connected, and the multiple circuit boards can be electrically connected sequentially or to each other. The multiple circuit boards can also be electrically connected by one or more circuit boards. The multiple circuit boards are located on different sides to define the placement cavity 25. The display 40 and the pin 31 are electrically connected to at least one circuit board. The transformer 24 is located in the placement cavity 25 and is electrically connected to at least one circuit board.

[0069] It is understandable that the number of circuit boards can be two, three, or more. Taking three circuit boards as an example, the main control chip and peripheral circuits can be integrated on the first circuit board, making the first circuit board the main board 21. The pin 31 is connected to the main board 21. The main board 21 can convert the AC power connected to the pin 31 into DC power and output DC power to the transformer 24. The second circuit board can be used as a protocol output board 22 to realize protocol communication and output power control functions. The third circuit board can be used as a control board 23, and the display screen 42 is electrically connected to the control board 23. The control board 23 mainly realizes logic information processing and outputs relevant charging information to the display screen 42, so that the display screen 42 can display charging information.

[0070] It should be noted that, compared to related technologies that integrate all functions onto a single board, resulting in a larger board size and consequently a larger plug size, this application uses multiple circuit boards, each responsible for different functions. Each circuit board is relatively small, making full use of the space within the housing 10, thereby reducing the plug size and making it more convenient to carry and store. Furthermore, by placing the transformer 24 within the placement cavity 25 formed by the multiple circuit boards, the arrangement of the electronic control components 20 becomes more compact, further reducing the overall size of the electronic control components 20 and consequently, the plug size.

[0071] In some embodiments, two adjacent circuit boards can be interlocked, allowing multiple circuit boards to be pre-fixed in a manner similar to rivet connection, and then assembled by welding or gluing, making circuit board installation more convenient.

[0072] In some embodiments, a heat-conducting element 60 is provided between at least one circuit board and the inner wall of the receiving cavity 11. The heat-conducting element 60 is in contact with the circuit board and the inner wall of the receiving cavity 11. The heat-conducting element 60 can evenly diffuse the heat generated by the electronic control component 20 to the housing 10, and then dissipate the heat through the housing 10. This can improve the heat dissipation efficiency of the electronic control component 20, prevent the plug from getting too hot during use, and ensure the heat dissipation performance of the charger when operating at high power. This allows the plug to maintain a relatively low temperature when charging at high power, thus extending the service life of the charger.

[0073] The heat-conducting element 60 can be a thermally conductive silicone pad. This pad has a certain degree of elasticity and can act as a buffer, thereby reducing the vibration transmitted from the housing 10 to the electronic control component 20 when the plug is dropped. Simultaneously, the thermally conductive silicone pad can fill the gap between the electronic control component 20 and the housing 10, preventing the electronic control component 20 from shaking or shifting position. Of course, in other embodiments, the heat-conducting element 60 can also be formed of other insulating and thermally conductive materials.

[0074] In some embodiments, thermally conductive materials such as thermally conductive adhesive or thermally conductive resin can be used to fill the space between the circuit board and the transformer 24, which can further improve the heat dissipation efficiency of the electronic control component 20.

[0075] In some embodiments, the electronic control component 20 further includes at least one insulating bracket 26, which isolates the AC circuit and DC circuit in the circuit board, thereby maintaining a safe distance between the AC circuit and DC circuit, which can improve the safety of the electronic control component 20 and thus improve the safety performance of the plug.

[0076] like Figure 11 As shown, in some embodiments, the plug further includes a male socket 71 and a female socket 72, one of which is disposed on the electrical control component 20 and the other is disposed on the display component 40.

[0077] In this embodiment, a pin is connected to one of the male socket 71 and the female socket 72. The pin is inserted into the other of the male socket 71 and the female socket 72 to electrically connect the display element 40 to the electrical control component 20. It is understood that given the small size of the plug, the space within the cavity 11 of the housing 10 is also small, making it difficult to achieve electrical connection between the display element 40 and the electrical control component 20 in such a confined space. However, in this embodiment, when electrically connecting the display element 40 to the electrical control component 20, it is only necessary to insert the pin from one of the male socket 71 and the female socket 72 into the other to achieve electrical connection. This makes the connection between the display element 40 and the electrical control component 20 more convenient and faster, solving the assembly problem in a confined space, thereby improving the production efficiency and assembly reliability of the plug.

[0078] Specifically, the male connector 71 can be soldered onto the circuit board, and the female connector 72 can be attached to the flexible circuit board 44 of the display screen 42. The female connector 72 has pins that extend along the arrangement direction of the display screen 42 and the circuit board. By inserting the pins into the socket of the male connector 71, the display screen 42 and the motherboard 21 can be electrically connected. Of course, in other embodiments, the male connector 71 can also be attached to the flexible circuit board 44 of the display screen 42, and the female connector 72 can be soldered onto the circuit board.

[0079] like Figures 12 to 14 As shown, in some embodiments, the plug further includes a resilient conductive element 80, which is installed within the receiving cavity 11 and located to the side of the pin 31. The pin 31 elastically abuts against the resilient conductive element 80 to electrically connect with the electronic control assembly 20 through the resilient conductive element 80, and to provide rotational resistance to the pin 31 through the resilient conductive element 80. It is understood that the resilient conductive element 80 is formed of a resilient conductive material (such as elastic steel), and the resilient conductive element 80 is capable of elastic deformation. The resilient conductive element 80 can be fixedly installed on the housing 10 and / or the electronic control assembly 20. The resilient conductive element 80 can act as an adapter between the pin 31 and the electronic control assembly 20, thereby enabling the electrical connection between the pin 31 and the electronic control assembly 20.

[0080] It should also be noted that, regardless of its position, pin 31 can maintain elastic contact with the elastic conductive element 80, ensuring that pin 31 experiences resistance from the elastic conductive element 80 during rotation, thus allowing pin 31 to stably remain in its retracted position (e.g., ...). Figure 15 ), first working position (e.g.) Figure 16 ) and second work position (e.g. Figure 17 This prevents pin 31 from rotating accidentally due to external force or vibration.

[0081] like Figures 14 to 17 As shown, in some embodiments, the elastic conductive member 80 is provided with a first slot 81 and a second slot 82 on the side facing the pin 31, such as... Figure 16 When pin 31 is in the first working position, pin 31 engages with the first slot 81; for example Figure 17 When pin 31 is in the second working position, pin 31 engages with the second slot 82.

[0082] Understandably, when the elastic conductive element 80 is engaged with the first slot 81 and the second slot 82, the elastic conductive element 80 can provide greater rotational resistance to the pin 31, enabling the pin 31 to lock in the first and second working positions. This allows the pin 31 to stay more stably in the first and second working positions, improving the reliability of the plug during operation. Furthermore, the pin 31 can rotate under external force (such as a person moving the pin 31), allowing it to disengage from the first slot 81 and the second slot 82 and unlock, thus ensuring that the pin 31 can smoothly rotate to other positions. In addition, the contact between the pin 31 and the slot wall of the first slot 81 and the second slot 82 increases the contact area between the pin 31 and the elastic conductive element 80, making the electrical connection between the pin 31 and the elastic conductive element 80 more stable.

[0083] In some embodiments, the elastic conductive element 80 includes a wiring portion 83 and an elastic portion 84 connected to the wiring portion 83. The elastic portion 84 is located to the side of the pin 31. It is understood that the wiring portion 83 is for electrical connection with the electronic control assembly 20. A first slot 81 and a second slot 82 are provided on the elastic portion 84. Both the elastic portion 84 and the wiring portion 83 are conductors. The elastic portion 84 and the wiring portion 83 can be integrally formed or formed separately and then spliced ​​together.

[0084] In some embodiments, the first slot 81 is located at the connection between the wiring portion 83 and the elastic portion 84, and the second slot 82 and the first slot 81 are arranged sequentially along the rotation trajectory of the pin 31. Figure 17 Taking the shown perspective as an example, when pin 31 is in the second working position, pin 31 is engaged with the second slot 82. At this time, rotating pin 31 counterclockwise disengages pin 31 from the second slot 82 and keeps it abutting against the elastic part 84. When pin 31 rotates to the first working position (e.g. Figure 16 The pin 31 engages with the first slot 81. Then, as the pin 31 continues to rotate counter-clockwise, it disengages from the first slot 81. When the pin 31 reaches the retracted position, it elastically contacts other parts of the elastic portion 84 (e.g., ...). Figure 15 ).

[0085] See also Figure 13 As shown, in some embodiments, the plug further includes a support shaft 32 located within the receiving cavity 11, and the pins 31 are connected to the support shaft 32 to be rotatably connected to the housing 10 via the support shaft 32, so that the pins 31 can rotate about the axis of the support shaft 32.

[0086] In some embodiments, the plug 31 includes a plug portion 311 and a contact portion 312 connected to the plug portion 311; the plug portion 311 passes through the recess opening 12 and is rotatably connected to the housing 10 via a support shaft 32 about the axis of the support shaft 32; the plug portion 311 is the part of the plug 31 used for plugging into the socket; the contact portion 312 is the part of the plug 31 used for contacting the elastic conductive member 80; both the contact portion 312 and the plug portion 311 are conductors; the contact portion 312 and the plug portion 311 can be integrally formed or separately formed and then spliced.

[0087] Furthermore, the contact portion 312 and the plug portion 311 are arranged at intervals along the extension direction of the axis of the support shaft 32. The elastic conductive element 80 is located on the side of the contact portion 312 and extends along the rotation trajectory of the contact portion 312, so that when the plug 31 rotates, the elastic conductive element 80 always elastically abuts against the contact portion 312, and the plug 31 can also rotate smoothly under the action of external force, preventing the plug 31 from being blocked by the elastic conductive element 80 and causing jamming.

[0088] The pin 31 can be formed together with the support shaft 32 by in-mold injection molding. The plug portion 311 is partially covered inside the support shaft 32, which can improve the connection strength between the pin 31 and the support shaft 32. The contact portion 312 extends out of the support shaft 32 to facilitate contact between the contact portion 312 and the elastic conductive element 80.

[0089] like Figures 18 to 21 As shown, in some embodiments, the support shaft 32 is rotatably connected to the housing 10 about its axis, and the pin 31 can rotate with the support shaft 32. The plug also includes an elastic limiting member 90, which is installed in the receiving cavity 11 and located to the side of the support shaft 32. A positioning protrusion 321 is provided on the outer periphery of the support shaft 32, and the positioning protrusion 321 elastically abuts against the elastic limiting member 90 to provide rotational resistance to the pin 31. It is understood that the elastic limiting member 90 can be formed of an elastic conductive material (such as elastic steel) or an elastic insulating material (such as elastic plastic), and the elastic limiting member 90 can undergo elastic deformation. The elastic limiting member 90 can be fixedly installed on the housing 10.

[0090] It should also be noted that, regardless of its position, pin 31 maintains elastic contact with the elastic limiting member 90. This ensures that pin 31 experiences resistance during rotation, increasing its rotational resistance and enhancing its stability in both the first and second working positions. This prevents pin 31 from becoming loose or making poor contact with the elastic conductive member 80. Furthermore, the rotational resistance provided by the elastic limiting member 90 to pin 31 can be adjusted by regulating the tightness of the contact between the elastic limiting member 90 and the positioning protrusion 321. This allows for adjustment of the user's feel when rotating pin 31, further enhancing the user experience.

[0091] In some embodiments, the elastic limiting member 90 includes a first limiting part 91, a second limiting part 92, and a connecting part 93; the second limiting part 92 is disposed at an angle to the first limiting part 91; the connecting part 93 is located between the first limiting part 91 and the second limiting part 92, and both ends of the connecting part 93 are respectively connected to the first limiting part 91 and the second limiting part 92, and a third slot 931 is provided on the side of the connecting part 93 facing the support shaft 32.

[0092] Specifically, when the pin 31 is in the retracted position, the positioning protrusion 321 elastically abuts against the first limiting part 91; when the pin 31 is in the first working position, the positioning protrusion 321 engages with the third slot 931; and when the pin 31 is in the second working position, the positioning protrusion 321 elastically abuts against the second limiting part 92. It can be understood that the first working position can be considered the commonly used working position of the pin 31. In the first working position, the engagement of the pin 31 with the first slot 81 and the engagement of the positioning protrusion 321 with the third slot 931 provides greater rotational resistance to the pin 31, thereby allowing the pin 31 to remain more stably in the first working position.

[0093] In some embodiments, the elastic limiting member 90 and the elastic conductive member 80 can be arranged along the axial direction of the support shaft 32, and the first limiting part 91 and the second limiting part 92 can be arranged along the circumferential direction of the support shaft 32, so that the positioning protrusion 321 always remains in contact with the elastic limiting member 90 during the rotation of the pin 31.

[0094] In other embodiments, the elastic limiting member 90 may be omitted, and the pin 31 may be provided with rotational resistance only by the elastic conductive member 80.

[0095] like Figure 12 As shown, in some embodiments, the housing 10 may also include a limiting cover 18, which is located on the side of the front cover 17 near the middle housing 16 and connected to the front cover 17. The support shaft 32, the elastic conductive element 80 and the elastic limiting element 90 may all be located between the limiting cover 18 and the front cover 17 to prevent the support shaft 32, the elastic conductive element 80 and the elastic limiting element 90 from detaching from the front cover 17.

[0096] In some embodiments, the plug may also include an AI chip that automatically identifies the brand, model, and battery health status of the device, thereby matching the most suitable charging power and optimizing charging efficiency. This allows the plug to support multiple charging modes such as "fast charging," "intelligent device protection," "battery maintenance," and "active device protection," balancing charging efficiency with battery protection.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
