Description

Technical Field

[0001] This application belongs to the technical field of electronic products, and specifically relates to a power adapter and electronic device components. Background Art

[0002] At present, some power adapters are provided with retractable pins, so as to better protect the pins and make the power adapter convenient to carry. However, if the pins need to be extended out of the bracket, the user needs to manually touch the pins and extend the pins out of the bracket, resulting in inconvenient use. Summary of the Invention

[0003] In view of this, in the first aspect of this application, a power adapter is provided, including:

[0004] A housing, on which a receiving groove and a first key hole are provided;

[0005] Pins, at least part of the pins are arranged in the receiving groove, and the pins are rotatably connected to the housing; at least part of the pins can be switched between a received state located in the receiving groove and an extended state located outside the receiving groove;

[0006] Two keys, at least part of the two keys are arranged on opposite sides of the pins, at least part of each key is arranged in the first key hole, and the keys are press-connectable to the housing; and

[0007] When the pins are in the extended state, the keys cooperate with the pins to limit the pins.

[0008] The power adapter provided in the first aspect of this application can realize the switching of at least part of the pins between a received state located in the receiving groove and an extended state located outside the receiving groove through the mutual cooperation of the pins and the keys. Among them, the received state refers to the state when all the pins are arranged in the receiving groove, and the extended state refers to the state when the pins can rotate relative to the housing and at least part of the pins are arranged outside the receiving groove. And when the pins are in the extended state, this application can also limit the pins through the mutual cooperation of the keys and the pins, that is, lock the pins, so as to improve the stability of the pins in the extended state and the convenience when plugging into the socket.

[0009] In addition, this application provides two buttons, and at least part of the two buttons is arranged on opposite sides of the pin. First, setting two buttons can further improve the limitation of the rotation of the pin by the buttons, and enhance the locking force by increasing the number of buttons. Second, arranging at least part of the two buttons on opposite sides of the pin facilitates the user to press and improves the stability of the power adapter. Third, when the number of buttons is two, only when the two buttons are pressed simultaneously can the abutting state between the button and the pin be released, and then the pin can rotate. This can reduce the risk of the pin rotating due to user's accidental operation compared with one button.

[0010] The second aspect of this application also provides a power adapter, including:

[0011] A housing, in which a receiving groove and a first button hole are formed, and a receiving space is provided inside the housing;

[0012] A pin, at least part of the pin is arranged in the receiving groove, the pin includes a rotating shaft and two pin columns connected to the same side of the rotating shaft, and the rotating shaft is rotatably connected to the housing; at least part of the pin can be switched between a receiving state located in the receiving groove and an extending state located outside the receiving groove;

[0013] Two buttons, at least part of the two buttons is arranged on opposite sides of the pin, at least part of each button is arranged in the first button hole, and the button is press-connectable to the housing; and

[0014] A driving member arranged in the receiving space, both ends of the driving member are respectively connected to the rotating shaft and the housing. When the pin is in the receiving state, the pin column and at least part of the driving member are arranged on the same side of the rotating shaft; and when the pin moves from the receiving state to the open state, the driving member drives at least part of the pin to rotatably extend out of the receiving groove.

[0015] For the power adapter provided by the second aspect of this application, through the mutual cooperation of the pin, the button and the driving member, the automatic extension of the pin is realized. Specifically, the driving member has the ability to drive the pin to rotatably extend out of the receiving groove. When the pin is in the receiving state, all pins are arranged in the receiving groove. At this time, the button abuts against the pin, so as to limit the rotation of the pin through the button, and thus the driving member cannot make the pin flip. But when the pin moves from the receiving state to the open state, the button will move under the external pressing force, so that the abutting state between the button and the pin is released. At this time, the button will no longer limit the rotation of the pin. Therefore, the driving member can drive at least part of the pin to rotatably extend out of the receiving groove, and finally realize automatic extension, improving the convenience of using the power adapter.

[0016] In addition, when the pin is in the received state, the present application can arrange the pin post and at least a part of the driving member on the same side of the rotating shaft. When the pin post is in the received state, at this time, the pin post is also arranged in the receiving groove. Therefore, the pin post will occupy a part of the space of the housing, and arranging at least a part of the driving member and the pin post on the same side of the rotating shaft can simplify the structure of the power adapter and reduce the overall size of the power adapter.

[0017] A third aspect of the present application provides an electronic device assembly, which includes an electronic device and a power adapter as provided in the first aspect of the present application. The power adapter is used for electrically connecting the electronic device, and the power adapter is also used for charging the electronic device when the pin is plugged into a power socket.

[0018] For the electronic device assembly provided in the third aspect of the present application, by adopting the power adapter provided in the first aspect of the present application, automatic extension of the pin can be achieved, improving the convenience during the use of the electronic device assembly. In addition, the locking force can be enhanced by increasing the number of buttons; the stability of the power adapter can be improved; and the risk of the pin rotating due to user's incorrect operation can also be reduced.

Detailed implementation manners

[0057] The following are the preferred implementation manners of the present application. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present application, several improvements and refinements can also be made, and these improvements and refinements are also regarded as the protection scope of the present application.

[0058] Please refer to Figures 1 - 5 , Figure 1 which is a three - dimensional structure schematic diagram of the power adapter in an embodiment of the present application. Figure 2 is Figure 1 the explosion diagram of Figure 3 which is a three - dimensional structure schematic diagram of the power adapter when the button is pressed in an embodiment of the present application. Figure 4 is Figure 3 the explosion diagram of Figure 5Explosion diagram of the power adapter in another embodiment of the present application. This embodiment provides a power adapter 1. Specifically, the power adapter 1 includes a housing 10, a plug 20, and two buttons 30. Among them, a receiving groove 11 and a first button hole 12 are formed on the housing 10. At least part of the plug 20 is disposed in the receiving groove 11, and the plug 20 is rotatably connected to the housing 10. At least part of the plug 20 can be switched between a received state located in the receiving groove 11 and an extended state located outside the receiving groove 11. At least part of the two buttons 30 is disposed on opposite sides of the plug 20, at least part of each button 30 is disposed in the first button hole 12, and the button 30 is press-connectable to the housing 10. When the plug 20 is in the extended state, the button 30 and the plug 20 cooperate with each other to limit the plug 20.

[0059] The power adapter 1 provided in this embodiment is a power supply conversion device for small portable electronic products and electronic appliances, and is widely used in devices such as telephone handsets, game consoles, mobile phones, laptop computers, etc. When the plug 20 of the power adapter 1 is inserted into a socket and the other end of the power adapter 1 is connected to the electronic device 3, electrical energy can be provided to the electronic device 3 to enable the electronic device 3 to work or charge normally.

[0060] The power adapter 1 provided in this embodiment includes a housing 10, which can provide a mounting foundation for other components of the power adapter 1 and can also protect the components disposed in the housing 10. Among them, a receiving groove 11 and a first button hole 12 are formed on the housing 10, and a receiving space 13 is provided inside the housing 10. The receiving groove 11 is used for mounting the plug 20 structure, the first button hole 12 is used for mounting the button 30, and the receiving space 13 is used for mounting the driving member 40.

[0061] Optionally, the housing 10 is not an integral structure but a split structure composed of two casings. Among them, part of the first button hole 12 is formed on each casing, and a complete first button hole 12 can be formed after the two casings are assembled together. Optionally, the power adapter 1 further includes other devices, such as a circuit board, a power chip, a power transformation module and other devices. These devices can be mounted in the receiving space 13 of the housing 10, and the plug 20 is electrically connected to these devices.

[0062] Optionally, the housing 10 provided in the present application has various combination forms. For example, the housing 10 provided in the present application can be a single housing structure, such as Figure 1 the bracket 100 type structure shown, or such as Figure 5 the outer shell 60 type structure shown. Or the housing 10 can also be a structure form in which two housings are combined. For example, it can be Figure 27The mating form of the bracket 100 shown and the outer shell 60. The bracket 100 is used to install structural components such as the pin 20, and then the bracket 100 is installed inside the outer shell 60. Any housing 10 that can install structural components such as the pin 20 and achieve the above functions shall fall within the protection scope of this application. In the following text of this application, the housing 10 is used as an example of the bracket 100 type structure for illustration.

[0063] The power adapter 1 provided in this embodiment further includes a pin 20. The power adapter 1 can be inserted into a power socket by using the pin 20, so that the power adapter 1 can obtain electric energy, thereby facilitating the transfer of electric energy to electronic devices 3 such as mobile phones, smart watches, laptop computers, tablet computers, and smart earphones. The pins 20 of the power adapter 1 can be pins 20 of various standards such as national standard, European standard, American standard, British standard, Australian standard, Japanese standard, and Korean standard. Among them, at least part of the pins 20 are arranged in the receiving groove 11.

[0064] In this application, the button 30 and the pin 20 cooperate with each other to enable at least part of the pins 20 to switch between a received state located in the receiving groove 11 and an extended state located outside the receiving groove. Among them, the received state refers to the state when all the pins 20 are arranged in the receiving groove 11 (as shown in Figure 1 ), and the extended state refers to the state when the pins 20 can rotate relative to the housing 10 and at least part of the pins 20 are arranged outside the receiving groove 11 (as shown in Figure 3 ). It can also be understood that when the button 30 is not pressed, the state when all the pins 20 are arranged in the receiving groove 11 is regarded as the received state. When the button 30 is pressed, the pins 20 can rotate relative to the housing 10 so that at least part of the pins 20 are arranged outside the receiving groove 11. At this time, it is regarded as the transition from the received state to the extended state. When the pins 20 rotate to the position, at least part of the pins 20 are arranged outside the receiving groove 11, and when the pressing force on the button 30 is removed, it is regarded as the extended state at this time. In the following text of this application, the state of the pins will be described according to the pressing situation of the button.

[0065] Optionally, when the button 30 is not pressed, all the pins 20 are arranged in the receiving groove 11, and when the button 30 is pressed, in this embodiment, part of the pins 20 are arranged in the receiving groove 11, and the remaining pins 20 are arranged outside the receiving groove for illustration. As for the specific location of the remaining pins 20, it will be introduced in detail in the following text of this application. In addition, the pins 20 are rotatably connected to the housing 10. It can also be understood that the pins 20 are not fixed relative to the housing 10 but have a rotational motion state, so that the pins 20 can be received in the receiving groove 11 or extended outside the receiving groove 11 to be inserted into the socket. Optionally, a metal conductor is provided at the end of the pins 20 to facilitate the conduction between the pins 20 and the power electrodes in the power socket.

[0066] The power adapter 1 provided by this embodiment further includes a button 30. The button 30 is one of the important structural components for controlling the movement state of the pin 20. The button 30 can be used as a movement switch trigger key for locking or unlocking the pin 20. At least part of each button 30 is disposed in the first button hole 12, and the button 30 is press-connectable to the housing 10. Optionally, when the button 30 is pressed, the button 30 can slide or move relative to the housing 10. The button 30 can be cooperatively connected to the pin 20 through the first button hole 12. A user or other object can press the button 30 to make the button 30 slide relative to the housing 10. Optionally, when the button 30 is not pressed, the pressing surface of the button 30 can protrude from the surface of the housing 10 for the user to press. After the button 30 is pressed, the button 30 can be received in the first button hole 12.

[0067] In addition, when the pin 20 is in the extended state, the present application can also limit the pin 20 through the cooperation of the button 30 and the pin 20, that is, lock the pin 20, which can facilitate the insertion of the pin 20 into the socket, thereby improving the stability and convenience of the pin 20 in the extended state. Optionally, when the pin 20 is in the received state, the present application can also limit the pin 20 through the cooperation of the button 30 and the pin 20. As for the specific structures of the button 30 and the pin 20, and how the button 30 and the pin 20 cooperate specifically to limit the pin 20 when it is in the received state and the extended state, the present application will be introduced in detail later.

[0068] In addition, two buttons 30 are provided in this embodiment, and at least part of the two buttons 30 is disposed on opposite sides of the pin 20. First, setting two buttons 30 can further improve the restriction of the rotation of the pin 20 by the button 30 compared to setting one button 30, and enhance the locking force by increasing the number of buttons 30. Second, disposing at least part of the two buttons 30 on opposite sides of the pin 20 is convenient for the user to press and improves the stability of the power adapter 1. Third, when the number of buttons 30 is two, only when the two buttons 30 are pressed simultaneously can the abutting state between the button 30 and the pin 20 be released, and then the pin 20 can rotate. This can reduce the risk of the pin 20 rotating due to user's misoperation compared to one button 30.

[0069] Optionally, please refer to again Figure 2 And Figure 4 , in this embodiment, the arrangement direction of the two buttons 30 (such as Figure 2 And Figure 4 The D1 direction in) is parallel to the direction of the rotation axis 21 line of the pin 20 (such as Figure 2 And Figure 4in the D1 direction). In this embodiment, the connection line of the centers of the two buttons 30 can be parallel to the rotation axis 21 line direction of the pin 20, so as to avoid the component force of the pressing force applied to the button 30 hindering the rotation of the pin 20 when the button 30 is pressed. In this embodiment, the arrangement direction of the two buttons 30 completely coincides with the rotation axis 21 line direction of the pin 20.

[0070] Please refer to again Figures 1 - 6 In this embodiment, the housing 10 has a receiving space 13, and the power adapter 1 further includes a driving member 40 disposed in the receiving space 13. Two ends of the driving member 40 are respectively connected to the pin 20 and the housing 10, so that when the pin 20 moves from the receiving state to the open state, the driving member 40 drives at least a part of the pin 20 to rotatably extend out of the receiving groove 11.

[0071] The power adapter 1 provided in this embodiment further includes a driving member 40. The driving member 40 is disposed in the receiving space 13, and the driving member 40 is connected to the pin 20. It can also be understood that one end of the driving member 40 is connected to the pin 20, and the other end of the driving member 40 is connected to the housing 10. This application will be introduced in detail later. The driving member 40 stores driving energy when all the pins 20 are disposed in the receiving groove 11, and it has the ability to drive the pin 20 to rotatably extend out of the receiving groove 11.

[0072] With the above structural components, in this embodiment, the automatic extension of the pin 20 can be achieved through the mutual cooperation of the pin 20, the button 30, and the driving member 40. Specifically, when the button 30 is not pressed, all the pins 20 are disposed in the receiving groove 11. At this time, it is the receiving state, which can also be understood as the non-working state. And disposing the pin 20 in the receiving groove 11 can reduce the overall size of the power adapter 1, and further facilitate the storage and carrying of the power adapter 1, and can also effectively protect the pin 20 from being damaged. At this time, the button 30 and the pin 20 are in mutual contact, that is, there will be partial contact between the button 30 and the pin 20; thus, the rotation of the pin 20 is restricted by the button 30, that is, the button 30 will not rotate and move at this time, so the pin 20 in contact with the button 30 will not rotate and move either. In this way, although the driving member 40 is connected to the pin 20 and the driving member 40 has a driving force, the driving member 40 cannot transmit the driving force to the pin 20 to make it flip.

[0073] When the button 30 is not pressed, all the pins 20 are disposed within the receiving groove 11, and the button 30 abuts against the pins 20 to restrict the rotation of the pins 20. However, when the button 30 is pressed, that is, when a pressing force from a user or other external source is applied to the button 30, the button 30 will move relative to the housing 10 under the action of the force, and further be received within the first button hole 12, thereby releasing the abutting state between the button 30 and the pins 20 and lifting the restriction on the rotation of the pins 20. The so-called "releasing the abutting state" can be understood as the separation of the contacting portions between the button 30 and the pins 20, that is, there is no contacting structure and surface between the button 30 and the pins 20, but the present application does not limit the positions of the button 30 and the pins 20. For example, when the button 30 and the pins 20 are in the released abutting state, the button 30 and the pins 20 can be completely separated macroscopically, that is, there is a certain distance between the button 30 and the pins 20. Alternatively, the button 30 and the pins 20 have a nested structural relationship. When the button 30 is not pressed, the nested portions of the button 30 and the pins 20 abut against each other; when the button 30 is pressed, the button 30 and the pins 20 still have a nested structure, but the button 30 and the pins 20 no longer contact each other at the nested portion, thereby achieving the release of the abutting state between the button 30 and the pins 20. At this time, the button 30 will no longer restrict the rotation of the pins 20. Therefore, the driving member 40 utilizes the driving force stored in advance to drive at least some of the pins 20 to rotatably extend out of the receiving groove 11, realizing the automatic extension of the pins 20, and finally inserting the pins 20 into a power socket for power transmission.

[0074] In summary, the above cooperation process can also be simply understood as: when the button 30 is not pressed, the pins 20 are restricted by the button 30 and cannot rotate; when the button 30 is pressed, the pins 20 can be automatically flipped and extended out of the receiving groove 11 under the drive of the driving member 40, and finally achieve automatic extension, improving the convenience of use of the power adapter 1.

[0075] In addition, after the pins 20 are flipped and extended relative to the housing 10, if the pressing force is removed, the button 30 can abut against the pins 20 again, thereby locking the pins 20 again. At this time, if it is desired to flip the pins 20 back into the receiving groove 11, the button 30 can be pressed again, and then a pressing force is applied to the pins 20, causing the pins 20 to flip and contract back relative to the housing 10. The flipping torque of the pins 20 can be transmitted back to the driving member 40 to enable the driving member 40 to store energy for the next time the pins 20 are extended. And after the flipping and contraction, if the pressing force is removed, the button 30 can abut against the pins 20 again, thereby locking the pins 20 again, thus completing the complete movement process of the power adapter 1 from the receiving state to the extended state and then back to the receiving state.

[0076] Optionally, the button 30 can limit or release the rotational torque transmission of the driving member 40 to the pin 20, so that at least a part of the pin 20 can be rotatably received or extended out of the receiving groove 11. The driving member 40 of the present application can provide various different types of driving forces to rotatably receive or extend the pin 20 out of the receiving groove 11. For example, rotational torque, sliding torque, or flipping torque, etc. This embodiment is illustrated with the driving force being rotational torque.

[0077] Further optionally, in order to enable the driving member 40 to store rotational torque, in this embodiment, the driving member 40 can be made elastic, that is, the driving member 40 is an elastic driving member 40. When the button 30 is not pressed (that is, when the pin 20 is in the receiving state), the driving member 40 is in an elastically deformed state, and at this time, the driving member 40 has an elastic restoring force (that is, driving force). When the button 30 is pressed (that is, when the pin 20 moves from the receiving state to the open state), the driving member 40 can release at least part of the elastic restoring force, so that at least a part of the pin 20 can be rotatably extended out of the receiving groove 11. In addition, according to the state of the driving member 40, it can be divided into a stretched state or a contracted state. Specifically, when the button 30 is not pressed, the driving member 40 is in a stretched state, and the driving member 40 has a tensile force; when the button 30 is pressed, the driving member 40 can release at least part of the tensile force. Or, when the button 30 is not pressed, the driving member 40 is in a compressed state, and the driving member 40 has a compressive force; when the button 30 is pressed, the driving member 40 can release at least part of the compressive force. As for the specific connection relationship and positional relationship of the driving member 40, this embodiment will be introduced in detail later. Optionally, the driving member 40 includes but is not limited to a spring.

[0078] Please refer to Figures 1 - 6 , Figure 6 which is a schematic structural diagram of a power adapter removing part of the bracket in an embodiment of the present application. In this embodiment, the number of the receiving grooves 11 is at least two, and the housing 10 is further provided with a boss 14, and at least two of the receiving grooves 11 are arranged corresponding to the circumferential side of the boss 14; the pin 20 includes a rotating shaft 21 and at least two pin columns 22 connected to one side of the rotating shaft 21, the rotating shaft 21 penetrates through the boss 14 and at least two of the receiving grooves 11, and the rotating shaft 21 is rotatably connected to the housing 10; at least two of the pin columns 22 can be rotatably received or extended out of at least two of the receiving grooves 11.

[0079] In this embodiment, the number of the receiving grooves 11 is at least two, and the at least two receiving grooves 11 are arranged corresponding to the circumferential side of the boss 14. Optionally, the boss 14 has a receiving groove 141 communicating with the receiving space 13. The pin 20 provided in this embodiment includes a rotating shaft 21 and at least two pin columns 22. The rotating shaft 21 mainly functions to rotate, while the pin columns 22 are used to be inserted into a socket. The rotation of the rotating shaft 21 can drive the pin columns 22 to rotate, so as to realize receiving or protruding from the at least two receiving grooves 11. In addition, the rotating shaft 21 of this embodiment can penetrate through the boss 14 and the at least two receiving grooves 11, that is, the rotating shaft 21 horizontally penetrates through the boss 14 and the receiving grooves 11. In this way, only part of the rotating shaft 21 is arranged in the receiving groove 11, and the rest of the rotating shaft 21 is arranged in the receiving groove 141 of the boss 14. In this way, not only can the boss 14 be used to separate the multiple receiving grooves 11, but also the boss 14 can be used to protect part of the rotating shaft 21 connected to the driving member 40 subsequently, and the boss 14 can also be used to cooperate and connect with other structures. Optionally, in this application, the number of the receiving grooves 11 is two and the number of the pin columns 22 is two for illustration.

[0080] Optionally, the length direction of the pin column 22 is perpendicular to the length direction of the rotating shaft 21. The central axis of the pin column 22 intersects with the central axis of the rotating shaft 21. The two pin columns 22 are arranged side by side in the axial direction of the rotating shaft 21.

[0081] Please refer to Figure 7 , Figure 7 which is a schematic structural diagram of a power adapter with part of the bracket removed in another embodiment. In this embodiment of the application, one end of the driving member 40 is connected to the rotating shaft 21, and the other end of the driving member 40 is connected to the housing 10; when the pin column 22 is arranged in the receiving groove 11, the pin column 22 and at least part of the driving member 40 are arranged on the same side of the rotating shaft 21.

[0082] As introduced above, one end of the driving member 40 is connected to the rotating shaft 21, thereby transmitting the driving force of the driving member 40 to the rotating shaft 21, so that the rotating shaft 21 rotates and then drives the pin post 22 to be rotatably received or extended out of the receiving groove 11. In this embodiment, the other end of the driving member 40 can be connected to the housing 10. Of course, in other embodiments, the other end of the driving member 40 can also be connected to other structures. In addition, when the pin post 22 is disposed in the receiving groove 11, at least a part of the driving member 40 and the pin post 22 are disposed on the same side of the rotating shaft 21. It can also be understood that when the pin post 22 is in the receiving state, at this time the pin post 22 is still disposed in the receiving groove 11, so the pin post 22 will occupy a part of the space of the housing, and arranging at least a part of the driving member 40 and the pin post 22 on the same side of the rotating shaft 21 can simplify the structure of the power adapter 1 and reduce the overall size of the power adapter 1. Optionally, the driving member 40 is hooked on the rotating shaft 21 and the housing 10. Optionally, when the number of the pin posts 22 is two, the driving member 40 is connected to the rotating shaft 21 between the two pin posts 22. This can make the driving force of the driving member 40 be more evenly transmitted to the rotating shaft 21 and improve the stability of the rotation of the pin 20.

[0083] Please refer to Figure 8 , Figure 8 for an embodiment of the present application Figure 1 which is a schematic view along the A-A direction. In this embodiment, one end of the driving member 40 is connected to the rotating shaft 21 passing through the boss 14, and one end of the driving member 40 is connected to the side of the rotating shaft 21 away from the receiving groove 11; when the button 30 is not pressed, the driving member 40 is in a stretched state.

[0084] This embodiment will introduce the specific structure for rotating the pin 20 by using the tensile force of the driving member 40. One end of the driving member 40 in this embodiment is connected to the rotating shaft 21 passing through the boss 14, and one end of the driving member 40 is connected to the side of the rotating shaft 21 away from the receiving groove 11, that is, connected to the lower side of the rotating shaft 21. Thus, when the button 30 is pressed, the driving member 40 will return from the stretched state to its original length, and during the process of returning to the original length, the driving member 40 will transmit the tensile force to the rotating shaft 21, pulling the rotating shaft 21 to rotate and driving the pin post 22 to rotate, and then making the pin post 22 extend out of the receiving groove 11.

[0085] Please refer to Figure 9 , Figure 9 for another embodiment of the present application Figure 1 which is a schematic view along the A-A direction. In this embodiment, one end of the driving member 40 is farther from the receiving groove 11 than the other end of the driving member 40.

[0086] This embodiment allows the driver 40 to be positioned at an angle, with one end of the driver 40 connected to the rotating shaft 21 positioned further away from the receiving slot 11 than the other end of the driver 40 connected to the housing 10. This increases the stretching length of the driver 40 within a similarly sized receiving space 13, thereby increasing the stretching force and facilitating the rotation of the pin 20. Furthermore, because the other end of the driver 40 is closer to the receiving slot 11 than one end of the driver 40, the rotation angle of the rotating shaft 21, and thus the rotation angle of the pin 20, is increased.

[0087] Please refer to Figure 10 , Figure 10 Another embodiment of this application Figure 1 In this embodiment, one end of the driving member 40 is connected to the rotating shaft 21 that passes through the boss 14, and one end of the driving member 40 is connected to a side of the rotating shaft 21 that is close to the receiving groove 11; when the button 30 is not pressed, the driving member 40 is in a compressed state.

[0088] This embodiment describes a specific structure that utilizes the compressive force of a driver 40 to rotate the pin 20. In this embodiment, one end of the driver 40 is connected to the rotating shaft 21, which extends through the boss 14. Another end of the driver 40 is connected to the side of the rotating shaft 21 closest to the receiving slot 11, that is, slightly above the rotating shaft 21. Consequently, when the button 30 is pressed, the driver 40 returns from its compressed state to its original length. During this return, the driver 40 transmits the compressive force to the rotating shaft 21, rotating the rotating shaft 21 and driving the pin 22 to rotate, thereby extending the pin 22 out of the receiving slot 11.

[0089] Please refer to Figure 11 , Figure 11 Another embodiment of this application Figure 1 In this embodiment, one end of the driving member 40 is closer to the receiving groove 11 than the other end of the driving member 40 .

[0090] This embodiment allows the driver 40 to be positioned at an angle, with one end of the driver 40 connected to the rotating shaft 21 positioned closer to the receiving slot 11 than the other end of the driver 40 connected to the housing 10. This increases the compression length of the driver 40 within a receiving space 13 of the same size, thereby enhancing the compression force and making it easier for the pin 20 to rotate. Furthermore, because the other end of the driver 40 is further away from the receiving slot 11 than the one end of the driver 40, the rotation angle of the rotating shaft 21, and therefore the rotation angle of the pin 20, can be increased.

[0091] The above content introduces the specific structure of the driving member 40. Next, this application will introduce the matching structure of the pin 20 and the button 30 in detail.

[0092] Please refer to Figures 12 - 13 , Figure 12 This is a schematic diagram of the structure of pins and buttons in one embodiment of the present application. Figure 13 This is an exploded view of a plug in one embodiment of the present application. In this embodiment, the plug 20 further includes a stopper 23 connected to the end of the rotation axis 21. When the button 30 is not pressed (i.e., when the plug 20 is in the retracted state), the button 30 and the end of the stopper 23 facing away from the rotation axis 21 abut against each other to restrict the rotation of the plug 20. When the button 30 is pressed (i.e., when the plug 20 moves from the retracted state to the open state), the button 30 and the end of the stopper 23 facing away from the rotation axis 21 are released from the abutment state, thereby releasing the restriction on the rotation of the plug 20.

[0093] In this embodiment, the pin 20 also includes a stopper 23. The end of the stopper 23 closest to the rotating shaft 21 is fixedly connected to the rotating shaft 21, while the end of the stopper 23 farther from the rotating shaft 21 cooperates with the button 30 to restrict the rotation of the pin 20. It will be understood that the stopper 23 is connected to the rotating shaft 21 so that when the stopper 23 moves, the rotating shaft 21 moves accordingly, and when the stopper 23 is stationary, the rotating shaft 21 remains stationary. When the stopper 23 is released from contact with the button 30, it can drive the rotating shaft 21 to rotate. When in contact with the button 30, the stopper 23 maintains its movement-restricting effect on the rotating shaft 21, keeping the rotating shaft 21 stationary relative to the housing 10. Furthermore, in this application, the stopper 23 and the button 30 form a nested structure, meaning that the button 30 can partially encase the stopper 23.

[0094] Please refer to Figures 13 - 17 , Figure 14 Schematic diagram of the structure of a button in one embodiment of the present application. Figure 15 This is a side view of the pins and buttons in one embodiment of the present application. Figure 16 In this application, when the button is not pressed Figure 15 Schematic diagram of the cross section along the BB direction. Figure 17 In one embodiment of the present application, when a button is pressed Figure 15Schematic cross-sectional view along the B-B direction. In this embodiment, a first limiting portion 24 is provided on the outer peripheral side wall of the end of the limiting member 23 facing away from the rotating shaft 21. A slot 31 for slidably inserting the limiting member 23 is provided at one end of the button 30 close to the limiting member 23. A second limiting portion 32 is provided on the inner peripheral side wall of the button 30 forming the slot 31. When the button 30 is not pressed (i.e., when the pin 20 is in the received state), the first limiting portion 24 and the second limiting portion 32 are in mutual abutment; when the button 30 is pressed (i.e., when the pin 20 changes from the received state to the open state), the second limiting portion 32 slides relative to the first limiting portion 24 to release the abutting state between the first limiting portion 24 and the second limiting portion 32.

[0095] In this embodiment, the button 30 and the limiting member 23 can be locked and fitted in a snap-fit manner. Specifically, a first limiting portion 24 is provided on the outer peripheral side wall of the end of the limiting member 23 facing away from the rotating shaft 21 (i.e., the end of the limiting member 23 close to the button 30). Optionally, the first limiting portion 24 can be a protrusion. A slot 31 is provided at one end of the button 30 close to the limiting member 23, and the above-mentioned nested structure is formed by using the slot 31, so as to realize the sliding fit between the button 30 and the limiting member 23. And a second limiting portion 32 is provided on the inner peripheral side wall of the button 30 forming the slot 31. Optionally, the second limiting portion 32 can also be a protrusion. Of course, the first limiting portion 24 and the second limiting portion 32 can also be of other structural forms.

[0096] As Figure 16 shown, when the button 30 is not pressed, the first limiting portion 24 and the second limiting portion 32 are in mutual abutment and cooperation to limit the relative rotation of the limiting member 23 with respect to the button 30, and further limit the relative rotation of the rotating shaft 21 and the pin column 22 with respect to the button 30. At this time, the button 30 cannot rotate relative to the housing 10, that is, the pin 20 cannot rotate relative to the housing 10 either.

[0097] As Figure 17 shown, when the button 30 is pressed, the button 30 will slide relative to the limiting member 23, that is, the second limiting portion 32 slides relative to the first limiting portion 24 (as Figure 17(As shown in the direction D2 in the figure), when the second limiting portion 32 moves beyond the axial dimension of the first limiting portion 24, although the button 30 and the housing 10 are still not nested, the first limiting portion 24 and the second limiting portion 32 in the slot 31 are no longer in contact. This can also be understood as a certain distance between the first limiting portion 24 and the second limiting portion 32 in the direction of the rotation axis 21 of the pin 20. Therefore, the limiting member 23 no longer restricts the rotation of the button 30, and consequently, the rotation axis 21 and the pin 22 are no longer restricted by the rotation of the button 30. The driving force of the driving member 40 can then drive the rotation axis 21 to rotate, thereby causing the pin 22 to rotatably extend out of the receiving slot 11.

[0098] Of course, in other embodiments, the stopper 23 and the button 30 can also be locked together using magnetic attraction. For example, a first magnet can be provided on the outer peripheral sidewall of the stopper 23 at the end facing away from the rotating shaft 21, and a second magnet can be provided on the inner peripheral sidewall of the button 30 forming the slot 31. When the button 30 is not pressed, the first and second magnets attract each other, securing the stopper 23 relative to the button 30, i.e., locking the button 30 with the pin 20. When the button 30 is pressed, the first and second magnets separate due to the external force, thereby separating the first and second magnets.

[0099] Optionally, a plurality of first limiting portions 24 are provided at intervals on the outer peripheral sidewall of the end of the limiting member 23 facing away from the rotation shaft 21. The plurality of first limiting portions 24 are symmetrically arranged around the central axis of the limiting member 23. A plurality of second limiting portions 32 are provided at intervals on the inner peripheral sidewall of the key 30 forming the slot 31. The plurality of second limiting portions 32 are symmetrically arranged around the central axis of the key 30. Further optionally, the central axis of the key 30, the central axis of the limiting member 23, and the rotation axis 21 of the rotation shaft 21 are coaxially arranged.

[0100] In addition, in one embodiment of the present application, when the driver 40 drives the pin 20 to rotate, the first limiting portion 24 rotates relative to the first limiting portion 24. At this time, the first limiting portion 24 may not be aligned with the gap between the two adjacent second limiting portions 32, so the blocking effect of the button 30 retracting the first limiting portion 24 cannot be reset. In this case, the pin 20 can be manually rotated so that the pin 20 is retracted into the receiving slot 11, and the first limiting portion 24 is realigned with the gap between the two adjacent second limiting portions 32, thereby resetting the button 30 to facilitate the next press of the button 30. During the process of manually pressing the pin 20 to retract it into the receiving slot 11, the rotational torque of the pin 20 can be transmitted to the driver 40, allowing the driver 40 to store driving force again and release the driving force after the button 30 is pressed next time.

[0101] Please refer to Figure 13 andFigure 18 , Figure 18 This is a schematic structural view of the limiting member in an embodiment of the present application. In this embodiment, a first connecting portion 25 is provided at one end of the limiting member 23 close to the rotating shaft 21, and a second connecting portion 26 is provided at one end of the rotating shaft 21 close to the limiting member 23. The first connecting portion 25 and the second connecting portion 26 cooperate with each other to connect the limiting member 23 to the rotating shaft 21.

[0102] In this embodiment, the rotating shaft 21 and the limiting member 23 are of a split structure. The first connecting portion 25 on the limiting member 23 and the second limiting portion 32 on the rotating shaft 21 cooperate with each other to connect the limiting member 23 to the rotating shaft 21, thereby realizing synchronous transmission of force. The first connecting portion 25 and the second connecting portion 26 can have various structural forms. Optionally, in this embodiment, the first connecting portion 25 is a card slot formed on one side surface of the limiting member 23, and the second limiting portion 32 is a card plate protruding from one side surface of the rotating shaft 21. The fixed connection is achieved by inserting the card plate into the card slot. Of course, the first connecting portion 25 can also be fixedly arranged by plugging, screwing, welding, etc. with the second connecting portion 26.

[0103] Please refer to Figure 19 , Figure 19 This is an exploded view of the elastic reset member, the pin, and the button in an embodiment of the present application. In this embodiment, the power adapter 1 further includes an elastic reset member 50. The elastic reset member 50 sleeves part of the limiting member 23. One end of the elastic reset member 50 abuts against the button 30, and the other opposite end of the elastic reset member 50 abuts against the rotating shaft 21; when the button 30 is pressed (that is, when the pin 20 changes from the receiving state to the open state), the elastic reset member 50 is in a compressed state. When the pressing force on the button 30 is zero, the button 30 can also return to the non-pressed state (that is, return to the original position) under the action of the sliding reset force of the elastic reset member 50.

[0104] As can be seen from the above, when the button 30 is pressed, the button 30 can linearly slide relative to the pin 20. In order to better reset the button 30, an elastic reset member 50 can be added in this embodiment, so that the elastic reset member 50 sleeves part of the limiting member 23, and one end of the elastic reset member 50 abuts against the button 30, and the other opposite end of the elastic reset member 50 abuts against the rotating shaft 21. When the button 30 is not pressed, the elastic reset member 50 is not stressed, or the elastic reset member 50 remains in a compressed state. When the button 30 is pressed, the button 30 slides relative to the pin 20, causing the button 30 to compress the elastic reset member 50. The two ends of the elastic reset member 50 are in the sliding direction of the button 30 (such as Figure 19It is compressed in the direction of D3 (as shown in the figure), so that the elastic resetting member 50 is in a compressed state. At this time, the elastic resetting member 50 has a compression force. When the user removes the pressing force, the pressing force on the button 30 is zero at this time. The elastic resetting member 50 will release the stored compression force, and both ends of the elastic resetting member 50 will open in the sliding direction of the button 30, and finally the button 30 will return to the position before being pressed.

[0105] It can be understood that in other embodiments of the present application, the elastic resetting member 50 can be replaced by other structural components that can store kinetic energy. For example, the component can be two mutually repulsive magnets, one magnet is fixed to the button 30, and the other is fixed to the limiting member 23. By moving the button 30 relative to the limiting member 23, the two magnets are compressed or stretched, that is, kinetic energy is stored or released, so as to meet the requirement that the button 30 can return to the state before being pressed after being pressed. Another example is that the component can be a piston arranged in the air chamber, and the piston is fixed to the limiting member 23. By moving the button 30 relative to the limiting member 23, the piston slides in the air chamber, and the gas in the air chamber is compressed or expanded, that is, kinetic energy is stored or released, so as to meet the requirement that the button 30 can return to the state before being pressed after being pressed. [[ID=]]

[0106] Please refer to Figures 20 - 22 , Figure 20 which is a schematic structural diagram of the pin and the button in another embodiment of the present application. Figure 21 In an embodiment of the present application, when the button is not pressed Figure 20 is a schematic cross-sectional view along the C-C direction in the figure. Figure 22 In an embodiment of the present application, when the button is pressed Figure 20 is a schematic cross-sectional view along the C-C direction in the figure. In this embodiment, the first limiting portion 24 rotates relative to the second limiting portion 32. When the pressing force on the button 30 is removed (when the pin 20 is in the open state), the rotated first limiting portion 24a abuts against the second limiting portion 32 to limit the rotation of the pin 20.

[0107] The above content introduces that when the button 30 is not pressed, the first limiting portion 24 abuts against the second limiting portion 32, so as to limit the rotation of the pin 20. And when the button 30 is pressed, the first limiting portion 24 and the second limiting portion 32 are staggered from each other, and the button 30 no longer limits the rotation of the pin 20 (i.e., the limiting member 23), so that the first limiting portion 24 can rotate relative to the second limiting portion 32. When the pressing force on the button 30 is removed, that is, when the pressing force on the button 30 is zero, the rotated first limiting portion 24a can correspond to the two adjacent second limiting portions 32 again and abut against the second limiting portion 32, so that the button 30 can still limit the rotation of the pin 20 after the pin 20 extends out.

[0108] Similarly, when the power adapter 1 is no longer in use, the button 30 can be pressed again to release the restriction on the movement of the pin 20, so as to push the pin 20 back into the receiving groove 11. Then, when the external force is removed, the first limiting portion 24 will abut against the second limiting portion 32 again, and further restrict the rotation of the button 30 to limit the rotation of the pin 20. It can also be simply understood that, regardless of the state, pressing the button 30 can release the restriction on the rotation of the pin 20, and when the pressing force on the button 30 is zero, the button 30 can limit the rotation of the pin 20.

[0109] Please refer to Figures 23 - 24 , Figure 23 which is a schematic diagram of the cooperation between the button and the bracket in an embodiment of the present application. Figure 24 which is a schematic diagram of the cooperation between the button and the bracket in another embodiment of the present application. In this embodiment, the housing 10 can restrict the rotation of the button 30, so that when the pin 20 is in the receiving state and the open state, after the button 30 and the housing 10 are in mutual abutting cooperation, the rotation of the pin 20 is restricted.

[0110] As can be seen from the above, when the button 30 is not pressed, the button 30 can restrict the rotation of the pin 20, so that the driving force of the driving member 40 cannot be transmitted to the pin 20. Therefore, in the present application, it is necessary to restrict the rotation of the button 30. In this embodiment, the rotation of the button 30 can be restricted by the cooperation between the housing 10 and the button 30, and then the rotation of the pin 20 can be restricted by the button 30. The present application provides two implementation manners, which are introduced in detail as follows.

[0111] Optionally, please refer to Figure 23 again. In the first embodiment provided by the present application, a protruding portion 33 is provided on the outer peripheral side wall of the button 30, and the protruding portion 33 abuts against the housing 10.

[0112] In the first implementation manner, a protruding portion 33 is provided on the outer peripheral side wall of the button 30, and the overall size of the button 30 and the protruding portion 33 is greater than the height of the housing 10. Therefore, when a part of the button 30 is installed in the first button hole 12, the protruding portion 33 on the button 30 can abut against the surface of the housing 10 to restrict the rotation of the housing 10. Optionally, four protruding portions 33 are provided on the outer peripheral side wall of the button 30, and the four protruding portions 33 are axially symmetrically arranged with respect to the central axis of the button 30, which can further improve the limiting effect of the housing 10 on the button 30. In addition, since the overall size of the button 30 and the protruding portion 33 is greater than the height of the housing 10, the overall size of the button 30 and the protruding portion 33 must also be greater than the size of the first button hole 12. In this way, when the button 30 returns to its original position under the action of the elastic reset member 50, the protruding portion 33 can be used to prevent the button 30 from falling off, so as to achieve the function of buckling the button 30.

[0113] Optionally, please refer to again Figure 24 In the second implementation manner provided by the present application, a first sliding portion 15 is provided on the inner peripheral side wall of the housing 10 forming the first key hole 12, and a second sliding portion 34 is provided on the outer peripheral side wall of the key 30. The first sliding portion 15 and the second sliding portion 34 cooperate with each other to enable the key 30 to slide relative to the housing 10, and can also limit the rotation of the key 30 relative to the housing 10.

[0114] In the second implementation manner, a first sliding portion 15 can be provided on the inner peripheral side wall of the housing 10 forming the first key hole 12, and a second sliding portion 34 can be provided on the outer peripheral side wall of the key 30. Optionally, the first sliding portion 15 includes but is not limited to a chute or a slider, and the second sliding portion 34 includes but is not limited to a slider or a chute. In this embodiment, the first sliding portion 15 is a chute and the second sliding portion 34 is a slider for illustration. By using the slider to slide in the chute, the sliding effect of the key 30 can be improved, and the rotation of the key 30 can also be limited by the side wall of the chute. Both of the two implementation manners provided by the present application can not only limit the rotation of the key 30, but also have their own unique performances, and users can choose according to their needs.

[0115] Please refer to together Figure 6 and Figure 25 , Figure 25 is a schematic perspective view of a power adapter in another embodiment of the present application. In this embodiment, an avoidance hole 16 is opened on the bottom wall of the housing 10 forming the receiving groove 11; or, an avoidance hole 16 is opened on the bottom wall of the housing 10 forming the receiving groove 11 and on the housing 10.

[0116] Since the receiving groove 11 is rectangular in this embodiment, when the key 30 is not pressed, both the rotating shaft 21 and the pin column 22 can be arranged in the receiving groove 11. However, when the key 30 is pressed, when the rotating shaft 21 rotates, it will hit the bottom wall of the receiving groove 11, thus hindering the rotation of the rotating shaft 21 and the pin column 22. Therefore, in this embodiment, an avoidance hole 16 can be opened on the bottom wall of the housing 10 forming the receiving groove 11. Or, avoidance holes 16 are opened on both the bottom wall of the housing 10 forming the receiving groove 11 and the housing 10. This can make the rotation of the rotating shaft smoother.

[0117] Optionally, in this embodiment, the side wall of the housing 10 forming the receiving groove 11 can limit the protrusion of the pin 20, and the bottom wall of the housing 10 forming the receiving groove 11 can limit the accommodation of the pin 20.

[0118] In this embodiment, in addition to providing the avoidance hole 16 on the bottom wall of the receiving groove 11, when the pin 20 is within the receiving groove 11, the bottom wall of the receiving groove 11 itself can limit the pin post 22 of the pin 20 to prevent the pin 20 from being overly received. When the pin 20 extends out of the receiving groove 11, the side wall of the receiving groove 11 adjacent to the rotating shaft 21 itself limits the pin 20 to prevent the rotation angle of the pin 20 from being too large, which is not conducive to the insertion of the pin 20 into the power socket. The rotating shaft 21 can be provided with an insulator that wraps one end of the pin post 22, and the rotating shaft 21 separates the two pin posts 22 to prevent the two pin posts 22 from being short-circuited. The pin post 22 is a metal part to enable the pin 20 to obtain current.

[0119] Please also refer to Figures 26 - 27 , Figure 26 which is a schematic structural diagram of the power adapter in another embodiment of the present application. Figure 27 is Figure 26 exploded view of. In this embodiment, the power adapter 1 further includes a housing 60 having an inner cavity 61 and a through groove 62 communicating with the inner cavity 61. The bracket 100 is received in the inner cavity 61, and the convex platform 14 is further configured to cooperate with the groove wall 65 of the through groove 62 to limit the bracket 100.

[0120] In this embodiment, in addition to including the bracket 100, the power adapter 1 may further include a housing 60, that is, the above-mentioned housing 10 is in the form of a combination of the bracket 100 and the housing 60. Among them, the housing 60 also serves as the housing of the power adapter 1. The bracket 100 can be fixed in the inner cavity 61 of the housing 60. The housing 60 provides stable protection for the bracket 100 and improves the appearance performance of the power adapter 1. The housing 60 is provided with an inner cavity 61 and a through groove 62 communicating with the inner cavity 61. The pin 20 can rotatably extend or retract from the through groove 62 relative to the housing 60. That is, the pin 20 is rotatably connected to the position where the bracket 100 faces the through groove 62. The button 30 passes through the housing 60 and is movably connected to the bracket 100. At least a part of the button 30 is exposed outside the housing 60 to facilitate the button 30 to receive the user's manipulation pressing force, so that the button 30 can move relative to the bracket 100 and the housing 60. Optionally, a second button hole 63 is further provided on the housing 60, and the button 30 is exactly corresponding to the first button hole 12 on the housing 60.

[0121] When the pin 20 extends relative to the bracket 100 and the outer shell 60, the end of the pin 20 rotatably connected to the bracket 100 is located in the receiving groove 11, and the other end is located outside the receiving groove 11. When the pin 20 is received relative to the bracket 100 and the outer shell 60, the pin 20 is completely received in the receiving groove 11 to achieve hidden protection for the pin 20 and reduce the volume of the power adapter 1 for easy carrying. When the pin 20 extends relative to the bracket 100 and the outer shell 60, the pin 20 can be inserted into a power socket, and the surface of the bracket 100 abuts against the power socket to prevent the outer shell 60 from contacting the power socket. The outer shell 60 protects the bracket 100. A circuit board electrically connecting the pin 20 can also be received in the outer shell 60 to facilitate the power adapter 1 to receive current and process the current.

[0122] It can be understood that the power adapter 1 adopts pins 20 that can be flipped out or received. In order to ensure that the pins 20 can be frequently flipped, the structural components that carry and rotatably connect the pins 20 have relatively high anti-fatigue requirements. The pins 20 need to obtain electrical energy when plugged into the power socket, so the pins 20 are often faced with the situation of arc combustion caused by high-voltage circuit short circuit. Therefore, to ensure the safety of the power adapter 1, the structural components that carry and connect the pins 20 have relatively high fire prevention and anti-combustion requirements. Obviously, in the embodiment of the present application, the bracket 100 carries the pins 20, the bracket 100 isolates the plugging from the outer shell 60, and the bracket 100 has better insulation protection performance, better wear and compression resistance performance, and better fire prevention and anti-combustion performance compared with the outer shell 60, which can ensure the safety of the power adapter 1 and increase the service life of the power adapter 1.

[0123] Please also refer to Figure 28 , Figure 28 is an exploded view of the power adapter in another embodiment of the present application. In this embodiment, the bracket 100 and a part of the outer shell 60 enclose to form the receiving space 13.

[0124] In the present application, the bracket 100 and the outer shell 60 can be two relatively independent structural components. That is, the bracket 100 has its own casing, and this casing encloses to form the receiving space 13 of the power adapter 1, and this casing is connected to the outer shell 60. Or, as in this embodiment, the bracket 100 and the outer shell 60 cooperate with each other. For example, the bracket 100 only has an upper casing, and a part of the outer shell 60 forms the lower casing of the bracket 100. The upper casing and this part of the outer shell 60 enclose the receiving space 13 of the bracket 100, and the other part of the outer shell 60 can extend to wrap part of the upper casing and form other spaces. This can save the lower casing of the bracket 100 and use part of the outer shell 60 as the lower casing, thereby reducing the thickness of the whole power adapter 1.

[0125] Please refer to again Figure 27, in this embodiment, an insertion hole 64 communicating the through groove 62 with the inner cavity 61 is formed in the outer shell 60. The bracket 100 can be inserted into the inner cavity 61 through the insertion hole 64, and the boss 14 is in limiting fit with the groove wall 65.

[0126] In this embodiment, an insertion hole 64 communicating the through groove 62 with the inner cavity 61 can be formed in the outer shell 60, so that the bracket 100 can be inserted into the inner cavity 61 through the insertion hole 64, thus completing the assembly. The inner peripheral side wall of the inner cavity 61 and the outer peripheral side wall of the bracket 100 are in clearance fit, so that after the bracket 100 is inserted into the inner cavity 61 through the insertion hole 64, it can be fixed in the inner cavity 61. One end of the through groove 62 away from the insertion hole 64 has a groove wall 65, and the groove wall 65 can limit the boss 14, so that the bracket 100 is inserted and limited inside, and the bracket 100 is prevented from shrinking too much inside the outer shell 60.

[0127] Please refer to Figure 29 , Figure 29 is an exploded view of a part of the structure of the power adapter in another embodiment of the present application. In this embodiment, the bracket 100 is provided with a first cover body 17 adjacent to the through groove 62 and a second cover body 18 covering the first cover body 17. The boss 14 is arranged on one side of the first cover body 17 facing away from the second cover body 18, and the rotating shaft 21 is rotatably connected between the first cover body 17 and the second cover body 18.

[0128] In this embodiment, the bracket 100 includes a first cover body 17 and a second cover body 18 covering the first cover body 17. The boss 14 is arranged on one side of the first cover body 17 facing away from the second cover body 18, and the rotating shaft 21 is rotatably connected between the first cover body 17 and the second cover body 18. The rotating shaft 21 is clamped by the first cover body 17 and the second cover body 18, so that the rotating shaft 21 rotates smoothly and steadily relative to the bracket 100.

[0129] Optionally, the abutting surface of the boss 14 is flush with the surface of the outer shell 60 to ensure the flatness of the appearance of the power adapter 1. In addition, there is a certain assembly step difference between the abutting surface and the surface of the outer shell 60. In order to ensure that the abutting surface always contacts the power socket prior to the surface of the outer shell 60, the abutting surface slightly protrudes from the outer surface of the outer shell 60. Optionally, the abutting surface of the boss 14 protrudes relative to the surface of the outer shell 60, that is, the end of the boss 14 protrudes relative to the surface of the outer shell 60, so that when the plug 20 is inserted into the power socket, there is always a certain distance between the outer shell 60 and the power socket to ensure the safety of the outer shell 60.

[0130] Please refer to Figures 30 - 31 , Figure 30 is a schematic structural diagram of the first cover body in an embodiment of the present application. Figure 31This is a schematic structural diagram of the second cover in an embodiment of the present application. In this embodiment, on the side of the first cover 17 facing the second cover 18, a protruding bearing boss 171 is formed corresponding to the receiving groove 11. On the side of the second cover 18 facing the first cover 17, a bearing protrusion 181 is provided for mating with the bearing boss 171. The rotating shaft 21 is rotatably connected between the bearing boss 171 and the bearing protrusion 181.

[0131] In this embodiment, a first U-shaped groove 172 is provided on the bearing boss 171, and a second U-shaped groove 182 is provided on the bearing protrusion 181. The first U-shaped groove 172 and the second U-shaped groove 182 jointly bear the rotating shaft 21 of the pin 20, enabling the pin 20 to rotate relative to the bracket 100. The first U-shaped groove 172 communicates with the receiving groove 11. Four first U-shaped grooves 172 are provided on each of the two side walls of the bearing boss 171, facilitating the rotating shaft 21 to pass through the receiving groove 11 via the first U-shaped groove 172. The pin column 22 is fixed to the part of the rotating shaft 21 passing through the receiving groove 11. The second cover 18 is provided with four bearing protrusions 181 corresponding to the four second U-shaped grooves 182 to enhance the structural stability between the rotating shaft 21 and the bracket 100, ensuring smooth rotation of the rotating shaft 21 relative to the bracket 100 and effectively isolating the two pin columns 22.

[0132] Please refer to Figure 32 , Figure 32 This is a partial structural exploded view of the power adapter in another embodiment of the present application. In this embodiment, the power adapter 1 further includes a pin elastic piece 70. One end of the pin elastic piece 70 is correspondingly clamped between the bearing boss 171 and the second cover 18. The opposite end of the pin elastic piece 70 elastically abuts against one end of the pin column 22 during the flipping process of the pin column 22 relative to the bracket 100.

[0133] In this embodiment, the power adapter 1 further includes two pin elastic pieces 70, and the two pin elastic pieces 70 are electrically connected to the two pin columns 22 respectively. The pin column 22 has a conductive contact 27 end away from the rotating shaft 21. When the pin 20 flips relative to the bracket 100 and extends out, the conductive contact 27 end elastically abuts against the pin elastic piece 70. When the pin 20 flips relative to the bracket 100 to the receiving state, the conductive contact 27 end separates from the pin elastic piece 70.

[0134] Specifically, the pin spring 70 includes a fixed end 71 and a curved end 72. The fixed end 71 corresponds to the end of the bearing boss 171 and is clamped to the inner wall bracket 100 of the second cover 18. The curved end 72 opposes the pin post 22 of the pin 20. The curved end 72 is curved and has elastic deformation properties. When the pin 20 is flipped and extended relative to the bracket 100, the conductive contact 27 rotates to contact the curved end 72, causing the curved end 72 to deform. The curved end 72 exerts an elastic resistance force on the conductive contact 27, further tightening the contact between the pin post 22 and the pin spring 70. This creates a damping force during the flipping process, that is, a damping force during the flipping of the pin 20 relative to the bracket 100, thereby reducing the impact force of the pin 20 on the bracket 100. When the pin 20 is flipped and accommodated relative to the bracket 100, the conductive contact 27 rotates to separate from the curved end 72, and the curved end 72 returns to its naturally extended state.

[0135] Please refer again Figure 32 In this embodiment, the first cover body 17 is further provided with a spring card slot 74 on one side of the bearing boss 171, and the pin spring 70 is provided with a conductive support leg 73 that is inserted into the spring card slot 74. The end of the rotating shaft 21 extends into the spring card slot 74 and contacts the conductive support leg 73, so that the pin column 22 maintains a conductive state with the conductive support leg 73 through the rotating shaft 21.

[0136] More specifically, the first cover 17 further includes a spring retaining slot 74 on one side of the bearing boss 171. The pin spring 70 includes a conductive leg 73 that engages with the spring retaining slot 74. The end of the rotating shaft 21 extends into the spring retaining slot 74 and contacts the conductive leg 73, thereby maintaining electrical contact between the pin 22 and the conductive leg 73 via the rotating shaft 21. The rotating shaft 21 also includes an axial conductor that contacts the two pins 22. The ends of the axial conductors extend into the spring retaining slot 74 and contact the conductive leg 73. The portions of the two axial conductors of the rotating shaft 21 that connect to the pins 22 are both insulated to prevent short circuits. The spring retaining slot 74 stabilizes the conductive leg 73, ensuring that the pin spring 70 maintains effective contact with the pin 20 even after the pin 20 is flipped multiple times relative to the bracket 100. This enhances the stability of the pin spring 70 and its effective electrical connection with the pin 20, thereby increasing the service life of the power adapter 1.

[0137] Please refer to Figures 33 - 34 , Figure 33 FIG. 1 is a partial cross-sectional diagram of a power adapter in one embodiment of the present application. Figure 34This is a partial cross-sectional schematic diagram of the power adapter in another embodiment of the present application. In this embodiment, the power adapter 1 further includes a transmission part 80 housed in the inner cavity 61. The transmission part 80 connects the button 30 and the plug 20. The transmission part 80 is used to convert the linear sliding torque of the button 30 into a rotational torque and transmit it to the plug 20, so that the plug 20 flips relative to the bracket 100.

[0138] The above content describes driving the rotation of the rotating shaft 21 by the driving member 40. In the present application, a transmission part 80 can also be added, so that the transmission part 80 connects the button 30 and the plug 20. The transmission part 80 is used to convert the linear sliding torque of the button 30 into a rotational torque and transmit it to the plug 20, so that the plug 20 flips relative to the bracket 100. By adding the transmission part 80, the sliding torque when the button 30 is pressed is utilized and converted into a rotational torque to be transmitted to the plug 20, further improving the rotational performance of the plug 20. Next, several structural forms of the present application will be briefly introduced.

[0139] Please refer to Figure 33 , in one implementation, the limiting member 23 can transmit the driving torque to the rotating shaft 21 through the transmission part 80, that is, the limiting member 23 is indirectly connected to the rotating shaft 21. For example, the limiting member 23 has a first connection end, and the first connection end transmits the rotational torque to the transmission part 80 through gear meshing. A gear is provided at the first connection end, and a gear or a gear set is provided on the transmission part 80, and the transmission part 80 meshes with the first connection end. After the limiting member 23 receives the rotational torque of the driving member 40, the first connection end transmits the rotational torque to the transmission part 80 through the meshing of the gear with the gear. The transmission part 80 is provided with a gear coaxial with the rotating shaft 21 and fixedly arranged with the rotating shaft 21, so that the transmission part 80 transmits the rotational torque to the rotating shaft 21. Finally, in the unlocked state, the limiting member 23 can transmit the rotational torque to the plug 20, so that the plug 20 can flip and extend relative to the bracket 100.

[0140] Please refer to Figure 34 , in another implementation, the linear sliding torque of the button 30 can be directly transmitted to the rotating shaft 21 of the plug 20 through the transmission part 80, so that the plug 20 can rotate to a state of extending relative to the bracket 100. Specifically, the transmission part 80 is provided with a transmission slider 81 fixedly connected to the button 30 and a worm 82 fixedly connected to the rotating shaft 21, and the transmission slider 81 meshes with the worm 82. By pressing the button 30, the button 30 drives the transmission slider 81 to slide relative to the bracket 100, and the transmission slider 81 drives the worm 82 to rotate, so that the worm 82 drives the rotating shaft 21 of the plug 20 to rotate, and finally the plug 20 flips relative to the bracket 100 to the extended state.

[0141] Based on the above, the power adapter 1 of the present application can also improve the structure of the housing 60. For example, it can provide another power adapter 1 that does not include the housing 60, or a power adapter 1 with a housing 60 of other structural forms. That is, the power adapter 1 of the present application does not limit the structural form of the housing 60 based on the above embodiments. Any solution that uses a similar method as in the above embodiments to release or limit the driving torque of the driving component to the pin 20 through the button 30, so that the pin 20 flips out or contracts relative to the bracket 100 is within the protection scope of the present application.

[0142] Optionally, in this embodiment, the power adapter 1 further includes a processor, a Bluetooth module, and a reminder. The Bluetooth module and the reminder are both electrically connected to the processor. The processor is configured to receive a first position signal through the Bluetooth module, and the processor is further configured to control the reminder to emit a reminder sound according to the first position signal. The processor is further configured to transmit a second position signal outward through the Bluetooth module.

[0143] In addition to the above mechanical structure in this embodiment, it may also include electronic structural components, such as a processor, a Bluetooth module, and a reminder. The present application can enable the power adapter 1 to have more functions through the mutual cooperation of the processor, the Bluetooth module, and the reminder. For example, since the power adapter 1 provided in this embodiment is relatively small in size. Therefore, users are prone to forget its location. In this way, the processor can receive the first position signal through the Bluetooth module. The first position signal can be information sent by other terminals such as a mobile phone or a laptop computer. After receiving the first position signal, the processor can control the reminder to emit a reminder sound according to the first position signal. For example, making the reminder emit a beeping sound to assist the user in knowing its location and finding the power adapter 1 more quickly. In addition, the processor can also transmit the second position signal outward through the Bluetooth module. Among them, the processor can actively transmit the second position signal outward through the Bluetooth module, or the user can press a dedicated switch on the adapter for transmission. When other terminals such as a mobile phone or a laptop receive it, they can also send a specific ringtone to assist the user in obtaining the location of the mobile phone or the laptop.

[0144] In addition to the structure of the power adapter 1 introduced above in this embodiment, this embodiment also provides another structure of the power adapter 1.

[0145] Please refer to again Figures 1 - 7, this embodiment provides a power adapter 1, where the power adapter 1 includes a housing 10, a plug 20, two buttons 30, and a driving member 40. A receiving groove 11 and a first button hole 12 are formed in the housing 10, and a receiving space 13 is provided inside the housing 10. At least part of the plug 20 is disposed in the receiving groove 11. The plug 20 includes a rotating shaft 21 and two pin columns 22 connected to the same side of the rotating shaft 21. The rotating shaft 21 is rotatably connected to the housing 10. At least part of the plug 20 can be switched between a receiving state located in the receiving groove 11 and an extended state located outside the receiving groove. At least part of the two buttons 30 is disposed on opposite sides of the plug 20, at least part of each button 30 is disposed in the first button hole 12, and the button 30 is press-connectable to the housing 10. The driving member 40 is disposed in the receiving space 13. Two ends of the driving member 40 are respectively connected to the rotating shaft 21 and the housing 10. When the plug 20 is in the receiving state, the pin columns 22 and at least part of the driving member 40 are disposed on the same side of the rotating shaft 21; and when the plug 20 is changed from the receiving state to the open state, the driving member 40 drives at least part of the plug 20 to rotatably extend out of the receiving groove 11.

[0146] Through the mutual cooperation of the plug 20, the button 30, and the driving member 40, the automatic extension of the plug 20 is achieved. Specifically, when the button 30 is not pressed, all the plugs 20 are disposed in the receiving groove 11. At this time, it is in the receiving state, which can also be understood as the non-working state. And disposing the plug 20 in the receiving groove 11 can reduce the overall size of the power adapter 1, thereby facilitating the storage and carrying of the power adapter 1, and can also effectively protect the plug 20 from being damaged. At this time, the button 30 and the plug 20 are in mutual contact, that is, there will be partial contact between the button 30 and the plug 20; thus, the rotation of the plug 20 is restricted by the button 30, that is, the button 30 will not rotate or move at this time, so the plug 20 in contact with the button 30 will not rotate or move either. In this way, although the driving member 40 is connected to the plug 20 and the driving member 40 has a driving force, the driving member 40 cannot transmit the driving force to the plug 20 to make it flip.

[0147] When the button 30 is not pressed, all the pins 20 are disposed within the receiving groove 11, and the button 30 abuts against the pins 20 to limit the rotation of the pins 20. However, when the button 30 is pressed, that is, when a pressing force from the user or other external sources is applied to the button 30, the button 30 will move relative to the housing 10 under the action of the force, and further be received within the first button hole 12, so that the button 30 and the pins 20 are disengaged from the abutting state, thereby releasing the restriction on the rotation of the pins 20. The so-called "disengaged from the abutting state" can be understood as the separation of the contacting portions between the button 30 and the pins 20, that is, there is no contacting structure and surface between the button 30 and the pins 20, but the present application does not limit the positions of the button 30 and the pins 20. For example, when the button 30 and the pins 20 are disengaged from the abutting state, the button 30 and the pins 20 can be completely separated macroscopically, that is, there is a certain distance between the button 30 and the pins 20. Or, the button 30 and the pins 20 have a nested structural relationship. When the button 30 is not pressed, the nested portions of the button 30 and the pins 20 abut against each other; when the button 30 is pressed, the button 30 and the pins 20 still have a nested structure, but the button 30 and the pins 20 no longer contact each other at the nested portion, thereby achieving the disengagement of the button 30 and the pins 20 from the abutting state. At this time, the button 30 will no longer restrict the rotation of the pins 20. Therefore, the driving member 40 utilizes the driving force stored in advance to drive at least some of the pins 20 to rotatably extend out of the receiving groove 11, realizing the automatic extension of the pins 20, and finally inserting the pins 20 into a power socket for power transmission.

[0148] In summary, the above cooperation process can also be simply understood as: when the button 30 is not pressed, the pins 20 are restricted by the button 30 and cannot rotate; when the button 30 is pressed, the pins 20 can be automatically flipped and extended out of the receiving groove 11 under the drive of the driving member 40, finally achieving automatic extension, which improves the convenience of using the power adapter 1.

[0149] In addition, when the pins 20 are in the receiving state, the present application can dispose the pin columns 22 and at least part of the driving member 40 on the same side of the rotating shaft 21. When the pin columns 22 are in the receiving state, at this time, the pin columns 22 are still disposed within the receiving groove. Therefore, the pin columns 22 will occupy a part of the space of the housing 10. Disposing at least part of the driving member 40 and the pin columns 22 on the same side of the rotating shaft 21 can simplify the structure of the power adapter 1 and reduce the overall size of the power adapter 1.

[0150] Optionally, the driving member is disposed between the two pin columns. When the number of the pin columns 22 is two, the driving member 40 is connected to the rotating shaft 21 between the two pin columns 22. This can make the driving force of the driving member 40 be transmitted to the rotating shaft 21 more evenly, improving the stability of the rotation of the pin 20. As for other structures, the structure of this embodiment is the same as that introduced in the above embodiment, that is, the specific structure introduced above is also applicable to the power adapter 1 provided in this embodiment.

[0151] Please refer to Figure 35 , Figure 35 which is a schematic diagram of an electronic device component in an embodiment of the present application. This embodiment provides an electronic device component 2, and the electronic device component 2 includes an electronic device 3 and a power adapter 1 provided in the above embodiment of the present application. The power adapter 1 is used for electrically connecting to the electronic device 3, and the power adapter 1 is further used for charging the electronic device 3 when the pin 20 is inserted into a power socket.

[0152] In addition to providing the power adapter 1, the present application also provides an electronic device component 2 using the power adapter 1. In addition to the power adapter 1, the electronic device component 2 further includes an electronic device 3. Among them, the electronic device 3 can be a mobile phone, a smart watch, a laptop computer, a tablet computer, a smart earphone and other devices. The electronic device 3 is provided with a power port 5. The power adapter 1 is provided with a charging end 4 electrically connected to the power port 5, and the charging end 4 can charge the power port 5 in a wired or wireless manner.

[0153] Optionally, the electronic device 3 is a mobile phone, and the power port 5 is disposed at the bottom end of the electronic device 3. The charging end 4 is inserted into the power port 5 and is electrically connected to the battery in the electronic device 3 through a cable. The power port 5 is a USB (Universal Serial Bus) interface, and the charging end 4 is a USB (Universal Serial Bus) plug. The charging end 4 is disposed at one end of the cable. The end of the cable away from the charging end 4 extends into the bracket 100 and is electrically connected to the pin elastic piece 70. When the pin 20 is flipped and extended relative to the bracket 100, the pin 20 is inserted into the power socket, so that the power adapter 1 obtains current. After the power adapter 1 processes the current, it is transmitted to the electronic device 3 through the charging end 4 to realize charging the electronic device 3. Optionally, the power adapter 1 is provided with a charging end 4, and the charging end 4 charges the electronic device 3 in a wired or wireless manner.

[0154] The electronic device component 2 provided by this embodiment can achieve the automatic extension of the pin 20 by using the power adapter 1 provided by the above embodiment of the present application, improving the convenience of using the electronic device component 2. In addition, the locking force can be enhanced by increasing the number of buttons 30; the stability of the power adapter 1 can be improved; and the risk of the pin 20 rotating due to the user's misoperation can also be reduced.
