when the pin is in the extended state, the key and the pin are matched with each other to limit the pin.

According to the power adapter provided by the first aspect of the application, at least part of the pins can be switched between the accommodating state in the accommodating grooves and the extending state outside the accommodating grooves through the mutual matching of the pins and the keys. The accommodating state refers to a state when all the pins are arranged in the accommodating grooves, and the extending state refers to a state when at least part of the pins are arranged outside the accommodating grooves and can rotate relative to the shell. And when participating in and be located the state of stretching out, this application still can be through button and participating in mutually supporting spacing participating in, carries out the locking to the plug promptly to improve the stability of participating in when the state of stretching out and the convenience when pegging graft the socket.

In addition, the pin is provided with two keys, and at least parts of the two keys are arranged on two opposite sides of the pin. Firstly, compared with the arrangement of one key, the arrangement of two keys can further improve the limitation of the keys on the rotation of the pin, and the locking force is enhanced by increasing the number of the keys. Secondly, at least part of two buttons are arranged on two opposite sides of the pin, so that the user can press the buttons conveniently, and the stability of the power adapter is improved. When the number of the keys is two, the abutting state of the keys and the pins can be released and the pins can be rotated only when the two keys are pressed simultaneously. This reduces the risk of the pins rotating due to a user mishandling relative to a single key.

The second aspect of the present application also provides a power adapter, including:

the key comprises a shell, a key body and a key cover, wherein the shell is provided with an accommodating groove and a first key hole, and an accommodating space is formed in the shell;

Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Referring to fig. 1 to 5, fig. 1 is a schematic perspective view of a power adapter according to an embodiment of the present disclosure. Fig. 2 is an exploded view of fig. 1. Fig. 3 is a schematic perspective view of a power adapter when a key is pressed according to an embodiment of the present application. Fig. 4 is an exploded view of fig. 3. Fig. 5 is an exploded view of a power adapter in another embodiment of the present application. The embodiment provides a power adapter 1, and specifically, the power adapter 1 includes a housing 10, a pin 20, and two keys 30. The housing 10 is provided with a receiving groove 11 and a first key hole 12. At least part of the pins 20 are arranged in the accommodating grooves 11, and the pins 20 are rotatably connected with the shell 10. At least a part of the pins 20 can be switched between a receiving state in the receiving slots 11 and an extending state outside the receiving slots 11. At least part of the two keys 30 are disposed on opposite sides of the pin 20, at least part of each key 30 is disposed in the first key hole 12, and the keys 30 are connected to the housing 10 in a pressing manner. When the pins 20 are in the extended state, the buttons 30 cooperate with the pins 20 to restrain the pins 20.

The power adapter 1 according to the present embodiment is a power supply conversion device for small portable electronic products and electronic appliances, and is widely used in devices such as a telephone set, a game machine, a mobile phone, a notebook computer, and the like. When the plug 20 of the power adapter 1 is inserted into the socket and the other end of the power adapter 1 is connected to the electronic device 3, the electronic device 3 can be powered to operate or charge the electronic device 3.

The power adapter 1 according to the present embodiment includes a housing 10, and can provide a mounting base for other components of the power adapter 1 and protect components provided in the housing 10. The housing 10 is provided with a receiving groove 11 and a first key hole 12, and the housing 10 has a receiving space 13 therein. The receiving groove 11 is used for receiving the pin 20 structure, the first key hole 12 is used for receiving the key 30, and the receiving space 13 is used for receiving the driving member 40.

Alternatively, the housing 10 is not an integral structure but a split structure composed of two housings. Each of the housings is provided with a portion of the first key hole 12, and when the two housings are assembled together, the complete first key hole 12 is formed. Optionally, the power adapter 1 further includes other devices, such as a circuit board, a power chip, a power transforming module, and the like. These devices may be installed in the receiving space 13 of the housing 10 and the pins 20 may be electrically connected to the devices.

Alternatively, the housing 10 provided herein may have a variety of combinations, for example, the housing 10 provided herein may be a single housing structure, such as a bracket 100 like structure shown in fig. 1, or a housing 60 like structure shown in fig. 5. Alternatively, the housing 10 may be formed by two housings, for example, a bracket 100 and a housing 60 as shown in fig. 27, the bracket 100 is used to mount the pins 20, and then the bracket 100 is mounted in the housing 60. It is within the scope of the present application that the housing 10 be capable of mounting the pins 20 and other structures to perform the above-described functions. The present application will be described with reference to the case 10 as a bracket 100.

The power adapter 1 provided by the embodiment further includes the plug pins 20, and the power adapter 1 can be plugged into a power socket by the plug pins 20, so that the power adapter 1 can obtain electric energy, and the electric energy can be conveniently transmitted to the electronic devices 3 such as a mobile phone, an intelligent watch, a notebook computer, a tablet computer, and an intelligent headset. The pins 20 of the power adapter 1 may be pins 20 of various standards such as national standard, european standard, american standard, english standard, australian standard, japanese standard, korean standard, and the like. At least a part of the pins 20 are disposed in the receiving slots 11.

The present application can switch at least a portion of the pins 20 between a receiving state in the receiving slots 11 and an extending state outside the receiving slots by cooperating the keys 30 with the pins 20. The accommodated state refers to a state (as shown in fig. 1) when all the pins 20 are disposed in the accommodating grooves 11, and the extended state refers to a state (as shown in fig. 3) when at least some of the pins 20 are disposed outside the accommodating grooves 11 and the pins 20 are rotatable relative to the housing 10. It is also understood that when the key 30 is not pressed, all the pins 20 are disposed in the receiving slots 11, i.e., the receiving state is determined. When the key 30 is pressed, the pins 20 can rotate relative to the housing 10, so that at least a portion of the pins 20 are disposed outside the accommodating grooves 11, and the state from the accommodated state to the extended state is determined. When the pins 20 are rotated to the proper position, at least a portion of the pins 20 are disposed outside the receiving slots 11, and when the pressing force on the key 30 is removed, the pins are determined to be in the extended state. The state of the pins will be explained in the following by the pressing condition of the key.

Alternatively, when the key 30 is not pressed, all the pins 20 are disposed in the receiving slots 11, and when the key 30 is pressed, the present embodiment is illustrated with some of the pins 20 disposed in the receiving slots 11 and the rest of the pins 20 disposed outside the receiving slots 11. As to where the remaining pins 20 are specifically located, the present application is described in detail below. In addition, the pin 20 is rotatably connected to the housing 10, and it can be understood that the pin 20 is not fixed with respect to the housing 10, but has a rotating motion state, so that the pin 20 can be accommodated in the accommodating groove 11, or the pin 20 can be extended out of the accommodating groove 11 to be inserted into the socket. Optionally, the ends of the pins 20 are provided with metallic conductors to facilitate the conduction of the pins 20 to the power supply electrodes in the power supply socket.

The power adapter 1 provided in this embodiment further includes a key 30, and the key 30 is one of important structural members for controlling the movement state of the pins 20. The key 30 may be used as a motion switch activation key for locking or unlocking the pin 20. At least a portion of each of the keys 30 is disposed in the first key hole 12, and the keys 30 are connected to the housing 10 in a pressing manner. Alternatively, the key 30 may slide or move relative to the housing 10 when the key 30 is pressed. The key 30 can be connected with the pin 20 through the first key hole 12. A user or other object may press the keys 30 to slide the keys 30 relative to the housing 10. Alternatively, when the key 30 is not pressed, the pressing surface of the key 30 may protrude from the surface of the housing 10 for the user to press. When the key 30 is pressed, the key 30 can be received in the first key hole 12.

In addition, when the pin 20 is in the extended state, the pin 20 can be limited by the key 30 cooperating with the pin 20, i.e. the pin 20 is locked, so that the pin 20 can be conveniently inserted into the socket, thereby improving the stability and convenience of the pin 20 in the extended state. Alternatively, the present application may limit the position of the pins 20 by the keys 30 cooperating with the pins 20 when the pins 20 are in the received state. As to the specific structure of the key 30 and the pin 20, and how the key 30 and the pin 20 are specifically matched to make the pin 20 in the receiving state and the extending state can be limited, the present application will be described in detail later.

In addition, the present embodiment provides two keys 30, and at least portions of the two keys 30 are provided on opposite sides of the pin 20. First, the provision of two keys 30 can further improve the restriction of the rotation of the pin 20 by the keys 30 as compared with the provision of one key 30, and enhance the locking force by increasing the number of keys 30. Secondly, providing at least part of the two keys 30 on opposite sides of the pins 20 facilitates the pressing by the user and improves the stability of the power adapter 1. When the number of the push buttons 30 is two, the push buttons 30 and the pins 20 are released from contact with each other and the pins 20 are rotated only when the two push buttons 30 are simultaneously pressed. This reduces the risk of the pin 20 rotating due to a user's wrong operation with respect to one of the keys 30.

Optionally, referring to fig. 2 and 4 again, in the present embodiment, the arrangement direction of the two keys 30 (e.g., the direction D1 in fig. 2 and 4) is parallel to the axial direction of the rotation axis 21 of the pin 20 (e.g., the direction D1 in fig. 2 and 4). The present embodiment can make the connection line of the centers of the two keys 30 parallel to the direction of the axis of rotation 21 of the pin 20, thereby avoiding the component of the pressing force applied to the keys 30 from obstructing the rotation of the pin 20 when the keys 30 are pressed. In this embodiment, the arrangement direction of the two keys 30 completely coincides with the axial direction of the rotation shaft 21 of the pin 20.

Referring to fig. 1 to 6 again, in the present embodiment, the housing 10 has an accommodating space 13 therein, the power adapter 1 further includes a driving member 40 disposed in the accommodating space 13, two ends of the driving member 40 are respectively connected to the pins 20 and the housing 10, so that when the pins 20 are in the accommodating state to the extending state, the driving member 40 drives at least a portion of the pins 20 to rotatably extend out of the accommodating grooves 11.

The power adapter 1 of the present embodiment further includes a driving member 40, the driving member 40 is disposed in the accommodating space 13, and the driving member 40 is connected to the pin 20. It is also 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, which will be described in detail later. The driving member 40 stores driving energy when all the pins 20 are disposed in the receiving slots 11, and has a capability of driving the pins 20 to rotatably protrude out of the receiving slots 11.

With the above structure, the present embodiment can realize the automatic extension of the pin 20 by the mutual cooperation of the pin 20, the button 30 and the driving member 40. Specifically, when the key 30 is not pressed, all the pins 20 are disposed in the housing groove 11, and in this case, the housing state is defined as the non-operating state. And the pins 20 are arranged in the accommodating grooves 11, so that the size of the whole power adapter 1 can be reduced, the power adapter 1 can be conveniently accommodated and carried, and the pins 20 can be effectively protected from being damaged. At this time, the key 30 and the pin 20 abut against each other, that is, parts of the key 30 and the pin 20 contact with each other; the rotation of the pin 20 is restricted by the button 30, that is, the button 30 does not rotate and move, and thus the pin 20 abutting against the button 30 does not rotate and move. Thus, 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 turn it.

When the key 30 is not pressed, all the pins 20 are disposed in the receiving slots 11, and the key 30 and the pins 20 abut against each other to limit the rotation of the pins 20. However, when the key 30 is pressed, that is, when the key 30 is pressed by a user or other external pressing force applied to the key 30, the key 30 is moved relative to the housing 10 by the force and is further accommodated in the first key hole 12, so that the key 30 and the pin 20 are released from the abutting state, and the rotation of the pin 20 is released. The "abutting state released" is understood to mean that the portion of the key 30 in contact with the pin 20 is separated, that is, the structure and surface of the key 30 not in contact with the pin 20, but the position of the key 30 and the pin 20 is not limited in the present application. For example, when the key 30 and the pin 20 are in the contact-released state, the key 30 and the pin 20 may be completely separated macroscopically, that is, the key 30 and the pin 20 have a certain distance. Or, the key 30 and the pin 20 are in a nested structure relationship, and when the key 30 is not pressed, the nested parts of the key 30 and the pin 20 are abutted with each other; when the key 30 is pressed, the key 30 and the pin 20 are still in a nested structure, but the key 30 and the pin 20 are not contacted with each other at the nested position, so that the abutting state of the key 30 and the pin 20 is released. At this time, the key 30 will not restrict the rotation of the pin 20, so the driving member 40 uses the driving force stored in advance to drive at least a portion of the pin 20 to rotatably extend out of the receiving slot 11, so as to realize the automatic extension of the pin 20, and finally the pin 20 is inserted into the power socket for power transmission.

In summary, the above-mentioned matching process can also be simply understood as follows: when the key 30 is not pressed, the pin 20 is restricted by the key 30 from rotating; when the button 30 is pressed, the pins 20 can be driven by the driving member 40 to automatically extend out of the receiving slots 11 in a turning manner, and finally, automatic extension is realized, so that convenience in use of the power adapter 1 is improved.

When the pin 20 is turned and extended with respect to the housing 10, the push button 30 may again abut against the pin 20 to lock the pin 20 again when the pressing force is removed. At this time, if the pin 20 is to be turned over again in the accommodating slot 11, the button 30 can be pressed again, and then the pressing force is applied to the pin 20, so that the pin 20 is turned over relative to the housing 10 and then contracted, and the turning torque of the pin 20 can be transmitted back to the driving member 40, so that the driving member 40 stores energy, and the pin 20 is extended again next time. And when the pressing force is removed after the power adapter 1 is turned over and contracted, the key 30 can abut against the pins 20 again to lock the pins 20 again, so that the complete movement process of the power adapter 1 from the accommodating state to the extending state and then to the accommodating state is completed.

Optionally, the key 30 can limit or release the transmission of the rotation torque of the driving member 40 to the pin 20, so that at least a portion of the pin 20 can rotatably receive or protrude from the receiving slot 11. The driving member 40 of the present application can provide a plurality of different types of driving forces to rotatably receive or extend the pin 20 from the receiving slot 11. Such as rotational torque, slip torque, or tumble torque, among others. The present embodiment is illustrated with the driving force as the rotational torque.

Further alternatively, in order to allow the driving member 40 to store a rotational torque, the present embodiment may provide the driving member 40 with elasticity, i.e. the driving member 40 is an elastic driving member 40. When the key 30 is not pressed (i.e. when the pin 20 is in the receiving state), the driving member 40 is in an elastically deformed state, and the driving member 40 has an elastic restoring force (i.e. a driving force). When the key 30 is pressed (i.e. when the pin 20 is in the receiving state to the extending state), the driving member 40 can release at least a portion of the elastic restoring force, so that at least a portion of the pin 20 can rotatably extend out of the receiving slot 11. In addition, the state may be classified into a stretching state or a contracting state according to the state of the driving member 40. Specifically, when the key 30 is not pressed, the driving member 40 is in a stretched state, and the driving member 40 has a stretching force; when the button 30 is depressed, the actuation member 40 may release at least a portion of the tensile force. Or, when the key 30 is not pressed, the driving member 40 is in a compressed state, and the driving member 40 has a compressive force; when the key 30 is pressed, the driving member 40 may release at least part of the compression force. As for the specific connection and position of the driving member 40, the present embodiment will be described in detail later. Alternatively, drive member 40 includes, but is not limited to, a spring.

Referring to fig. 1 to fig. 6, fig. 6 is a schematic structural diagram of a power adapter with a portion of a bracket removed according to an embodiment of the present application. In this embodiment, the number of the accommodating grooves 11 is at least two, the housing 10 is further provided with a boss 14, and at least two accommodating grooves 11 are provided corresponding to the peripheral side of the boss 14; the pin 20 comprises 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 the at least two accommodating grooves 11, and the rotating shaft 21 is rotatably connected with the housing 10; at least two of the pin columns 22 are rotatably received in or protrude out of at least two of the receiving slots 11.

In the present embodiment, the number of the receiving grooves 11 is at least two, and at least two receiving grooves 11 are provided corresponding to the circumferential side of the boss 14. Optionally, the boss 14 has a receiving groove 141 therein, which communicates with the receiving space 13. The pin 20 provided in this embodiment includes a rotation shaft 21 and at least two pin columns 22. Wherein the rotation shaft 21 mainly functions as a rotation and the pin post 22 is used for insertion into a socket. The rotation of the rotating shaft 21 drives the pin column 22 to rotate, so as to realize the accommodation or extend out of at least two accommodation grooves 11. In addition, the rotating shaft 21 of the present embodiment may penetrate the boss 14 and at least two of the receiving slots 11, that is, the rotating shaft 21 transversely penetrates the boss 14 and the receiving slot 11, such that only a portion of the rotating shaft 21 is disposed in the receiving slot 11, and the remaining rotating shafts 21 are disposed in the receiving slots 141 of the boss 14, such that not only the plurality of receiving slots 11 can be separated by the boss 14, but also a portion of the rotating shaft 21 connected to the driving member 40 later can be protected by the boss 14, and the boss 14 can be used to be connected to other structures. Optionally, the number of the receiving slots 11 is two, and the number of the lead posts 22 is two for illustration in the present application.

Alternatively, the length direction of the pin post 22 is perpendicular to the length direction of the rotation shaft 21. The center axis of the pin 22 intersects the center axis of the rotary shaft 21. The two pin columns 22 are arranged side by side in the axial direction of the rotating shaft 21.

Referring to fig. 7, fig. 7 is a schematic structural diagram of a power adapter with a portion of a bracket removed according to another embodiment. In the present embodiment of the present application, one end of the driving element 40 is connected to the rotating shaft 21, and the other end of the driving element 40 is connected to the housing 10; when the pin column 22 is disposed in the accommodating groove 11, the pin column 22 and at least a portion of the driving member 40 are disposed on the same side of the rotating shaft 21.

It is described above that one end of the driving member 40 is connected to the rotating shaft 21, so as to transmit the driving force of the driving member 40 to the rotating shaft 21, so that the rotating shaft 21 rotates to drive the pin 22 to be rotatably received in or extend out of the receiving slot 11. The other end of the driving member 40 may be connected to the housing 10 in this embodiment, but other structures may be connected to the other end of the driving member 40 in other embodiments. When the pin 22 is disposed in the receiving groove 11, the pin 22 and at least a portion of the driving member 40 are disposed on the same side of the rotating shaft 21. It can also be understood that when the pin 22 is in the receiving state, the pin 22 is still disposed in the receiving slot 11, so that the pin 22 occupies a part of the housing space, and at least a portion of the driving member 40 and the pin 22 are disposed on the same side of the rotating shaft 21, which simplifies the structure of the power adapter 1 and reduces the overall size of the power adapter 1. Alternatively, the driving member 40 is hooked on the rotating shaft 21 and the housing 10. Alternatively, when the number of the lead posts 22 is two, the driving member 40 is connected to the rotating shaft 21 between the two lead posts 22. This allows the driving force of the driving member 40 to be more uniformly transmitted to the rotary shaft 21, thereby improving the stability of the rotation of the pin 20.

Referring to fig. 8, fig. 8 is a schematic view along a direction a-a in fig. 1 according to an embodiment of the present disclosure. In this embodiment, one end of the driving element 40 is connected to the rotating shaft 21 penetrating through the boss 14, and one end of the driving element 40 is connected to a side of the rotating shaft 21 away from the accommodating groove 11; when the button 30 is not pressed, the driving member 40 is in a stretched state.

The present embodiment will describe a specific structure for rotating the pins 20 by the tensile force of the driving member 40. In the present embodiment, one end of the driving member 40 is connected to the rotating shaft 21 penetrating through the boss 14, and one end of the driving member 40 is connected to a side of the rotating shaft 21 away from the accommodating groove 11, that is, to a lower side of the rotating shaft 21. Thus, when the key 30 is pressed, the driving member 40 returns to the original length from the stretched state, and in the process of returning to the original length, the tensile force is transmitted to the rotating shaft 21, the rotating shaft 21 is pulled to rotate and the pin 22 is driven to rotate, so that the pin 22 extends out of the receiving slot 11.

Referring to fig. 9, fig. 9 is a schematic view taken along a direction a-a in fig. 1 according to another embodiment of the present disclosure. In the present embodiment, one end of the driving member 40 is spaced apart from the accommodating groove 11 with respect to the other end of the driving member 40.

In the present embodiment, the driving member 40 may be disposed to be inclined, that is, one end of the driving member 40 connected to the rotation shaft 21 is far from the accommodating groove 11 relative to the other end of the driving member 40 connected to the housing 10. This first increases the length of the extension of the drive element 40 in the accommodation space 13 of the same size range, which increases the extension force and makes the rotation of the foot 20 easier. Secondly, since the other end of the driving member 40 is closer to the accommodating groove 11 than the one end of the driving member 40, the rotation angle of the rotation shaft 21 and thus the rotation angle of the pin 20 can be increased.

Referring to fig. 10, fig. 10 is a schematic view taken along a direction a-a in fig. 1 according to another embodiment of the present disclosure. In this embodiment, one end of the driving element 40 is connected to the rotating shaft 21 penetrating through the boss 14, and one end of the driving element 40 is connected to a side of the rotating shaft 21 close to the accommodating groove 11; when the button 30 is not depressed, the actuating member 40 is in a compressed state.

The present embodiment will describe a specific structure for rotating the pin 20 by the compression force of the driving member 40. In the present embodiment, one end of the driving member 40 is connected to the rotating shaft 21 penetrating through the boss 14, and one end of the driving member 40 is connected to a side of the rotating shaft 21 close to the accommodating groove 11, that is, to an upper side of the rotating shaft 21. Thus, when the key 30 is pressed, the driving member 40 returns from the compressed state to the original length, and transmits the compression force to the rotating shaft 21 in the process of returning to the original length, so as to push the rotating shaft 21 to rotate and drive the pin 22 to rotate, thereby extending the pin 22 out of the receiving slot 11.

Referring to fig. 11, fig. 11 is a schematic view taken along a direction a-a in fig. 1 according to another embodiment of the present disclosure. In the present embodiment, one end of the driving member 40 is close to the accommodating groove 11 relative to the other end of the driving member 40.

In the present embodiment, the driving member 40 may be disposed to be inclined, that is, one end of the driving member 40 connected to the rotation shaft 21 is close to the receiving groove 11 relative to the other end of the driving member 40 connected to the housing 10. This first increases the compression length of the driver 40 within the same size range of the receiving space 13, thereby increasing the compression force and making the pin 20 easier to rotate. Secondly, since the other end of the driving member 40 is farther away from the receiving slot 11 than the one end of the driving member 40, the rotation angle of the rotation shaft 21 and thus the rotation angle of the pin 20 can be increased.

The above description describes the specific structure of the driving member 40, and the present application will describe the matching structure of the pin 20 and the key 30 in detail.

Please refer to fig. 12-13, fig. 12 is a schematic structural diagram of a pin and a key according to an embodiment of the present application. Fig. 13 is an exploded view of a pin according to an embodiment of the present application. In this embodiment, the pin 20 further includes a limiting member 23 connected to an end of the rotating shaft 21, and when the key 30 is not pressed (i.e., when the pin 20 is in the accommodating state), one ends of the key 30 and the limiting member 23 facing away from the rotating shaft 21 abut against each other to limit the rotation of the pin 20; when the push button 30 is pressed (i.e., when the pin 20 is in the accommodated state to the extended state), the push button 30 may be released from the abutting state with the end of the stopper 23 away from the rotating shaft 21, so as to release the restriction on the rotation of the pin 20.

In this embodiment, the pin 20 further includes a limiting member 23, wherein one end of the limiting member 23 close to the rotating shaft 21 is used for being fixedly connected with the rotating shaft 21, and one end of the limiting member 23 away from the rotating shaft 21 is used for being matched with the key 30 to limit the rotation of the pin 20. It will be understood that the limiting member 23 is connected to the rotating shaft 21, such that the rotating shaft 21 moves when the limiting member 23 moves, and the rotating shaft 21 is stationary when the limiting member 23 is stationary. The stopper 23 can rotate the rotating shaft 21 in a state where the stopper is released from contact with the push button 30. The stopper 23 keeps the movement of the rotary shaft 21 restricted so that the rotary shaft 21 is kept stationary with respect to the housing 10 in a state where the stopper and the push button 30 are in abutting engagement with each other. In addition, in the present application, the position limiting element 23 and the key 30 are nested structures, that is, the key 30 can be sleeved with a portion of the position limiting element 23.

Please refer to fig. 13-17, and fig. 14 is a schematic structural diagram of a key according to an embodiment of the present application. FIG. 15 is a side view of a pin and a key according to an embodiment of the present application. FIG. 16 is a schematic cross-sectional view taken along the direction B-B in FIG. 15 when the key is not pressed according to one embodiment of the present application. FIG. 17 is a schematic cross-sectional view taken along the line B-B in FIG. 15 when a key is pressed according to an embodiment of the present application. In this embodiment, an outer peripheral sidewall of one end of the limiting member 23 away from the rotating shaft 21 is provided with a first limiting portion 24, one end of the key 30 close to the limiting member 23 is provided with a slot 31 in sliding insertion with the limiting member 23, and an inner peripheral sidewall of the slot 31 formed by the key 30 is provided with a second limiting portion 32. When the key 30 is not pressed (i.e. the pin 20 is in the receiving state), the first position-limiting part 24 and the second position-limiting part 32 abut against each other; when the push button 30 is pressed (i.e., when the pin 20 is in the accommodated state to the extended state), the second stopper 32 slides relative to the first stopper 24, so that the first stopper 24 and the second stopper 32 are released from the abutting state.

In the present embodiment, the key 30 and the stopper 23 may be locked and engaged with each other by engaging with each other. Specifically, a first limiting portion 24 is disposed on a peripheral sidewall of an end of the limiting member 23 away from the rotating shaft 21 (i.e., an end of the limiting member 23 close to the key 30). Alternatively, the first stopper portion 24 may be a projection. The end of the key 30 close to the limiting member 23 is provided with a slot 31, and the slot 31 is used to form the above-mentioned nested structure, so as to realize the sliding fit between the key 30 and the limiting member 23. And a second limiting portion 32 is provided on the inner peripheral side wall of the key 30 forming the slot 31. Alternatively, the second position-limiting portion 32 may be a protrusion. Of course, the first position-limiting portion 24 and the second position-limiting portion 32 may have other structures.

As shown in fig. 16, when the key 30 is not pressed, the first position-limiting portion 24 and the second position-limiting portion 32 are abutted and matched with each other to limit the rotation of the position-limiting member 23 relative to the key 30, and further limit the rotation of the rotating shaft 21 and the pin 22 relative to the key 30. At this time, the key 30 cannot rotate relative to the housing 10, i.e., the pin 20 cannot rotate relative to the housing 10.

As shown in fig. 17, when the push button 30 is pressed, the push button 30 slides relative to the stopper 23, that is, the second stopper portion 32 slides relative to the first stopper portion 24 (as shown in a direction D2 in fig. 17), and when the distance that the second stopper portion 32 moves exceeds the axial dimension of the first stopper portion 24, although the push button 30 and the housing 10 are still not nested, the first stopper portion 24 and the second stopper portion 32 in the slot 31 are released from the abutting state and do not abut. It can also be understood that the first position-limiting portion 24 and the second position-limiting portion 32 have a certain distance in the direction of the rotation axis 21 of the pin 20. Therefore, the limiting member 23 is no longer limited by the rotation of the key 30, and the rotating shaft 21 and the pin 22 are no longer limited by the rotation of the key 30, and the driving force of the driving member 40 can drive the rotating shaft 21 to rotate, so as to drive the pin 22 to rotatably extend out of the receiving slot 11.

Of course, in other embodiments, the limiting member 23 and the key 30 may also be locked and engaged in a magnetic manner, for example, an outer peripheral sidewall of one end of the limiting member 23 away from the rotating shaft 21 is provided with a first magnet, and an inner peripheral sidewall of the key 30 forming the slot 31 is provided with a second magnet. When the key 30 is not pressed, the first magnet and the second magnet attract each other, so that the retaining member 23 is fixed relative to the key 30, i.e. the key 30 is locked with the pin 20. When the key 30 is pressed, the first magnet is separated from the second magnet due to the separation of the first magnet from the second magnet caused by an external force.

Optionally, a plurality of first limiting portions 24 are disposed at intervals on an outer peripheral sidewall of one end of the limiting member 23 away from the rotating shaft 21. The plurality of first stopper portions 24 are arranged symmetrically around the central axis of the stopper 23. The inner peripheral side wall of the slot 31 formed by the key 30 is provided with a plurality of second limiting parts 32 arranged at intervals. The plurality of second stoppers 32 are symmetrically arranged around the central axis of the key 30. Further alternatively, the central axis of the key 30, the central axis of the stopper 23, and the axis of rotation 21 of the rotation shaft 21 are coaxially arranged.

In addition, in one embodiment of the present application, when the driving element 40 drives the pin 20 to rotate, the first position-limiting portion 24 rotates relatively. At this time, the first position-limiting portion 24 may not be aligned with the gap between two adjacent second position-limiting portions 32, so that the key 30 cannot be reset by the blocking effect of the first position-limiting portion 24. At this time, the pin 20 can be rotated manually, so that after the pin 20 is retracted into the receiving slot 11, the first position-limiting portion 24 is aligned with the gap between the two adjacent second position-limiting portions 32 again, thereby resetting the key 30, so as to facilitate the next pressing of the key 30. During the process of manually pressing the pin 20 to retract into the slot 11, the rotational torque of the pin 20 can be transmitted to the driving member 40, so that the driving member 40 can store the driving force again to release the driving force after the key 30 is pressed next time.

Please refer to fig. 13 and 18 together, and fig. 18 is a schematic structural diagram of a position limiting element according to an embodiment of the present application. In this embodiment, a first connecting portion 25 is disposed at one end of the limiting member 23 close to the rotating shaft 21, a second connecting portion 26 is disposed at one end of the rotating shaft 21 close to the limiting member 23, and the first connecting portion 25 and the second connecting portion 26 are mutually matched to connect the limiting member 23 to the rotating shaft 21.

In the present embodiment, the rotating shaft 21 and the limiting member 23 are of a split structure, and the first connecting portion 25 on the limiting member 23 and the second limiting portion 32 on the rotating shaft 21 are engaged with each other, so that the limiting member 23 and the rotating shaft 21 are connected to realize synchronous force transmission. The first connection portion 25 and the second connection portion 26 may have various structural forms. Alternatively, in the present embodiment, the first connecting portion 25 is a slot opened on one side surface of the limiting member 23, and the second limiting portion 32 is a clip protruding on one side surface of the rotating shaft 21. The clamping plate is inserted into the clamping groove to realize fixed connection. Of course, the first connection portion 25 may be fixedly inserted into the second connection portion 26, fixedly screwed, fixedly welded, or the like.

Referring to fig. 19, fig. 19 is an exploded view of the elastic reset element, the pin and the key according to an embodiment of the present disclosure. In this embodiment, the power adapter 1 further includes an elastic reset member 50, the elastic reset member 50 is sleeved on a portion of the limiting member 23, one end of the elastic reset member 50 abuts against the key 30, and the other end of the elastic reset member 50 opposite to the key abuts against the rotating shaft 21; when the key 30 is pressed (i.e. the pins 20 are in the accommodated state to the extended state), the elastic reset element 50 is in a compressed state, and when the pressing force on the key 30 is zero, the key 30 can be restored to an un-pressed state (i.e. restored to the original position) by the sliding reset force of the elastic reset element 50.

As can be seen from the above, when the key 30 is pressed, the key 30 can slide linearly with respect to the pin 20. In order to better restore the key 30, in the present embodiment, an elastic restoring member 50 may be additionally disposed, such that the elastic restoring member 50 is sleeved on a portion of the limiting member 23, one end of the elastic restoring member 50 abuts against the key 30, and the other end of the elastic restoring member 50 opposite to the key abuts against the rotating shaft 21. The elastic restoring member 50 is not stressed when the key 30 is not pressed, or the elastic restoring member 50 maintains a compressed state. When the key 30 is pressed, the key 30 slides relative to the pins 20, so that the key 30 compresses the elastic restoring member 50, and both ends of the elastic restoring member 50 are compressed in the sliding direction (as shown in the direction D3 in fig. 19) of the key 30, so that the elastic restoring member 50 is in a compressed state, and the elastic restoring member 50 has a compression force. When the user removes the pressing force, the pressing force on the key 30 is zero, the elastic restoring member 50 releases the stored compressive force, and the two ends of the elastic restoring member 50 are opened in the sliding direction of the key 30, so that the key 30 is finally restored to the non-pressed position.

It is understood that in other embodiments of the present application, the elastic restoring element 50 may be replaced by another structural element capable of storing kinetic energy, for example, the structural element may be two mutually repulsive magnets, one of which is fixed to the key 30 and the other is fixed to the retaining element 23, and the two magnets are compressed or extended by the movement of the key 30 relative to the retaining element 23, that is, the kinetic energy is stored or released, so that the key 30 can be restored to the non-pressed state after the key 30 is pressed. For another example, the component may be a piston disposed in the air cavity, the piston fixes the limiting member 23, and the piston slides in the air cavity by the movement of the key 30 relative to the limiting member 23, so that the gas in the air cavity is compressed or expanded, that is, the kinetic energy is stored or released, so as to meet the requirement that the key 30 can be restored to the non-pressed state after the key 30 is pressed.

Please refer to fig. 20-22, fig. 20 is a schematic structural diagram of a pin and a key according to another embodiment of the present application. FIG. 21 is a schematic cross-sectional view taken along the direction C-C in FIG. 20 when a key is not pressed according to an embodiment of the present application. FIG. 22 is a schematic cross-sectional view taken along the direction C-C in FIG. 20 when a key is pressed according to an embodiment of the present application. In this embodiment, the first stopper portion 24 rotates relative to the second stopper portion 32, and when the pressing force on the key 30 is removed (when the pin 20 is in the extended state), the rotated first stopper portion 24a and the second stopper portion 32 abut against each other to restrict the rotation of the pin 20.

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

Similarly, after the power adapter 1 is used, the key 30 can be pressed again to contact the limitation on the movement of the pin 20, so as to push the pin 20 to return to the receiving slot 11 again, and then the external force is removed to make the first position-limiting portion 24 abut against the second position-limiting portion 32 again, so that the key 30 limits the rotation of the pin 20 again. It can also be simply understood that, regardless of the state, pressing the key 30 contacts the restriction of the rotation of the pin 20, and when the pressing force on the key 30 is zero, the key 30 restricts the rotation of the pin 20.

Please refer to fig. 23-24, fig. 23 is a schematic diagram illustrating a key and a bracket according to an embodiment of the present application. Fig. 24 is a schematic view illustrating a key and a bracket according to another embodiment of the present disclosure. In this embodiment, the housing 10 may limit the rotation of the key 30, so that when the pin 20 is located in the receiving state and the extending state, the key 30 and the housing 10 are abutted and engaged with each other to limit the rotation of the pin 20.

As can be seen from the above, when the button 30 is not pressed, the button 30 can limit the rotation of the pin 20, so that the driving force of the driving member 40 cannot be transmitted to the pin 20. Therefore, the present application needs to limit the rotation of the key 30, in this embodiment, the housing 10 cooperates with the key 30 to limit the rotation of the key 30, and then the key 30 is used to limit the rotation of the pin 20. The present application provides two implementations, described in detail below.

Optionally, referring to fig. 23 again, in the first embodiment provided in the present application, a protruding portion 23 is disposed on a peripheral sidewall of the key 30, and the protruding portion 23 abuts against the housing 10.

In the first implementation manner, the protrusion 23 is disposed on the peripheral sidewall of the key 30, and the overall size of the key 30 and the protrusion 23 is greater than the height of the casing 10, so that when a part of the key 30 is installed in the first key hole 12, the protrusion 23 on the key 30 can abut against the surface of the casing 10, thereby restricting the rotation of the casing 10. Optionally, four protrusions 23 are disposed on the peripheral sidewall of the key 30, and the four protrusions 23 are disposed in axial symmetry with respect to the central axis of the key 30, so that the limiting effect of the housing 10 on the key 30 can be further improved. In addition, since the overall size of the key 30 and the protruding portion 23 is larger than the height of the housing 10, the overall size of the key 30 and the protruding portion 23 is also larger than the size of the first key hole 12, so that when the key 30 is restored to the original position under the action of the elastic restoring member 50, the protruding portion 23 can be used to prevent the key 30 from falling off, thereby realizing the function of locking the key 30.

Optionally, referring to fig. 24 again, in a second embodiment provided by the present application, an inner peripheral sidewall of the housing 10 forming the first key hole 12 is provided with a first sliding portion 15, an outer peripheral sidewall of the key 30 is provided with a second sliding portion 34, and 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 further, the key 30 is restricted from rotating relative to the housing 10.

In a second implementation manner, the first sliding portion 15 may be provided on the inner peripheral side wall of the casing 10 where the first key hole 12 is formed, and the second sliding portion 34 may 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 sliding slot or a sliding block, and the second sliding portion 34 includes, but is not limited to, a sliding block or a sliding slot. In the present embodiment, the first sliding portion 15 is illustrated as a chute, and the second sliding portion 34 is illustrated as a slider. The sliding block slides in the sliding groove, so that the sliding effect of the key 30 is improved, and the side wall of the sliding groove can be used for limiting the rotation of the key 30. The two implementation modes provided by the application can not only realize the rotation of the limit key 30, but also have respective unique performance, and a user can select according to the requirement.

Please refer to fig. 6 and 25 together, and fig. 25 is a schematic perspective view of a power adapter according to another embodiment of the present application. In this embodiment, the bottom wall of the housing 10 forming the accommodating groove 11 is provided with an avoiding hole 16; alternatively, the housing 10 forms a bottom wall of the receiving groove 11, and the housing 10 is provided with a relief hole 16.

Since the housing groove 11 is rectangular in the present embodiment, the rotation shaft 21 and the pin 22 can be disposed in the housing groove 11 when the key 30 is not pressed. However, when the push button 30 is pressed, the rotation shaft 21 hits the bottom wall of the housing groove 11 when rotated, thereby blocking the rotation of the rotation shaft 21 and the pin post 22. Therefore, in the present embodiment, the bottom wall of the housing 10 forming the receiving groove 11 may be provided with a relief hole 16. Alternatively, the bottom wall of the housing 10 forming the receiving groove 11 and the housing 10 are both provided with avoiding holes 16. This makes the rotation of the rotary shaft smoother.

Optionally, in this embodiment, the side wall of the housing 10 forming the accommodating groove 11 may limit the protrusion of the pin 20, and the bottom wall of the housing 10 forming the accommodating groove 11 may limit the accommodation of the pin 20.

In this embodiment, in addition to forming the avoiding hole 16 on the bottom wall of the receiving slot 11, when the pin 20 is located in the receiving slot 11, the bottom wall of the receiving slot 11 can limit the pin post 22 of the pin 20 to prevent the pin 20 from being excessively received. When the pin 20 extends out of the receiving slot 11, the side wall of the receiving slot 11 adjacent to the rotating shaft 21 limits the pin 20, so as to prevent the pin 20 from rotating too much, which is not favorable for the pin 20 to be plugged into the power socket. The shaft 21 may be provided with an insulator covering one end of the pin posts 22, and the shaft 21 separates the two pin posts 22 to prevent the two pin posts 22 from short-circuiting. The pin post 22 is a metal piece to enable the pin 20 to draw current.

Referring to fig. 26 to 27 together, fig. 26 is a schematic structural diagram of a power adapter according to another embodiment of the present application. Fig. 27 is an exploded view of fig. 26. In this embodiment, the power adapter 1 further includes a housing 60, the housing 60 has an inner cavity 61 and a through slot 62 communicating with the inner cavity 61, the bracket 100 is accommodated in the inner cavity 61, and the boss 14 is further configured to cooperate with a slot wall 65 of the through slot 62 to limit the bracket 100.

In this embodiment, the power adapter 1 may further include a housing 60 in addition to the bracket 100, that is, the housing 10 is a fitting form of the bracket 100 and the housing 60. Wherein, the casing 60 also acts as the casing of the power adapter 1, the bracket 100 can be fixed in the inner cavity 61 of the casing 60, the casing 60 can stably protect the bracket 100, and the appearance performance of the power adapter 1 is enhanced. The housing 60 is provided with an inner cavity 61 and a through slot 62 communicating with said inner cavity 61. The pins 20 are rotatably extended or retracted from the through slots 62 relative to the housing 60. I.e., the prongs 20 are pivotally connected to the bracket 100 directly opposite the channel 62. The key 30 is movably coupled to the bracket 100 through the housing 60. The keys 30 are at least partially exposed out of the housing 60 so that the keys 30 receive a user's manipulation pressing force to allow the keys 30 to move relative to the bracket 100 and the housing 60. Optionally, the housing 60 is further provided with a second key hole 63, and the housing 60 of the key 30 just corresponds to the first key hole 12.
