Wherein the size of the pin receiving groove 103 is matched with and larger than the size of the pin so as to receive the pin therein.
As shown in fig. 1 and 2, the foldable plug assembly includes at least two prongs 102 spaced apart from each other. The pins 102 may include pins complying with safety standards of various countries, for example, pins complying with safety standards of countries such as china, the united states, japan, the united kingdom, and the like. In the present embodiment, the foldable plug assembly of the present invention is mainly explained and illustrated by taking the structure of two pins 102 spaced apart from each other as an example, but it should be noted that the structure of the pins is not limited to the above structure, and other suitable structures are also possible.
Alternatively, as shown in fig. 3, at least two pins 102 spaced apart from each other are connected by a rotation shaft 104, and the pins 102 are rotated by the rotation of the rotation shaft. Wherein the rotation shaft 104 is disposed at one end of the pin 102 for electrically connecting with the conductive elastic sheet, and is away from one end of the pin 102 for electrically connecting with the power source.
In one example, as shown in fig. 8, the rotation shaft 104 is a cam structure, and the rotation shaft of the cam structure needs to have enough space under it during rotation, otherwise rotation cannot be achieved, and in addition, when the foldable plug assembly is mounted to the device body and the pins are opened, the cam structure abuts against the second locking member, so that the second locking member is moved downward to be connected to the device body, and the foldable plug assembly and the device body cannot be separated. Optionally, the rotating shaft 104 of the cam structure includes a cam 1041 protruding outward in the radial direction of the rotating shaft, and the cam 1041 is disposed eccentrically to the axis of the rotating shaft.

In one example, as shown in fig. 5, the second locking member includes a second detent structure 1091, the second detent structure 1091 engaging the device body when the foldable plug assembly is mounted to the device body and the prongs are in the open position such that the foldable plug assembly and the device body cannot be separated. As shown in fig. 2, a through hole 1084 is disposed on the bottom of the housing, the through hole 1084 penetrates through the bottom of the housing and is configured to allow the second detent structure 1091 to move up and down therein, for example, the through hole 1084 is disposed on the bottom housing 108.
The shape of the second detent structure 1091 may be any suitable shape, such as a cylinder, for example, a first end of the second detent structure 1091 located in the accommodating space of the housing has a smaller size than a second end opposite to the first end.
In one example, as shown in fig. 5, the second locking member further includes a fixing member 1093 disposed in the accommodating space of the housing, and the fixing member 1093 is connected to a first end of the second detent structure 1091 located in the accommodating space, so as to limit the second detent structure 1091 from being disengaged from the housing. For example, the second blocking structure 1091 passes through the through hole 1084 from the outside of the housing and is connected to the fixing member 1093 disposed in the accommodating space of the housing, so that the second blocking structure 1091 does not fall off from the housing. The fixing member 1093 may be connected by any suitable means, such as welding, bonding, screwing, etc., and in this embodiment, the fixing member 1093 and the second detent structure 1091 are connected by a screw 1094.
In one example, as shown in fig. 5, the second locking element further comprises a second reset structure 1092, wherein one end of the second reset structure 1092 abuts against the fixing member 1093, and the other end abuts against the bottom of the housing, so as to reset the second detent structure 1091. Wherein the second return structure 1092 may comprise a return spring, or other suitable return structure, wherein the return spring may be in a compressed state or a naturally extended state in an initial state, i.e., without the second locking element being subjected to other external forces.
In one example, as shown in fig. 9, when the foldable pin assembly is not mounted to the device body and the pins are in the folded state, the top end of the second locking member can abut against the pivot shaft 104 to assist in limiting the pivot of the pivot shaft, e.g., by urging the second locking member (e.g., the top end of the fixing member 1094) against the lower end of the pivot shaft 104 by the second restoring structure 1092 to assist in limiting the pivot of the pivot shaft so that the pins cannot be opened and the strong insertion connection force cannot be used normally, i.e., in the safe state. Alternatively, in other embodiments, it is also possible that the top end of the second locking member has a predetermined distance from the rotating shaft, which is smaller than the pivoting space of the cam of the rotating shaft, so that the cam of the rotating shaft can apply downward pressure to the second locking member to couple the second locking member to the device body when the prongs are opened.
As shown in fig. 2 and 9, when the foldable prong assembly is not mounted to the device body and the prongs are in the folded state, the second locking member is in the stowed state under the action of the second return structure 1092, which does not protrude outside the housing, i.e., the second detent structure 1091 does not protrude outside the housing.
As shown in fig. 3 and 4, if the prongs 102 are not restrained by the first locking member and can be opened, the cam 1054 of the pivot shaft exerts a downward force on the second locking member to cause a portion of the second detent structure 1091 to partially protrude out of the housing and thereby be available for connection to the device body.
In one example, the foldable plug assembly further comprises a mounting assembly (not shown) disposed on the housing for detachably mounting the foldable plug assembly to a device body. Wherein, the mounting assembly can be arranged on the bottom shell or the face shell. For example, the mounting assembly is disposed on the fixed structure 1080.
Optionally, the mounting assembly includes a power transfer assembly (not shown) electrically connected to the pins, when mounted to the device body, to a power input interface of the device body.
Alternatively, the bottom shell 108 may be any suitable shape, wherein the bottom shell 108 may include only a bottom plate to cover the opening in the bottom of the face shell 101, or the bottom shell 108 may further include a bottom plate and a vertically disposed mounting plate disposed at one end of the bottom plate, the mounting plate and the face shell being snap-coupled.
As shown in fig. 7 and 9, when the foldable plug assembly is not connected to the device body (i.e. mounted to the device body), the front shell 101 and the bottom shell 108 are firmly combined to form a housing of the foldable plug assembly, which can be regarded as an integral non-detachable member, and no relative displacement occurs, and at this time, the pins 102 are kept in a folded and retracted state, i.e. a locked state, if the pins 102 need to be opened, as shown in fig. 9, the rotating shaft 104 needs to rotate 90 ° in a counterclockwise direction indicated by an arrow in the figure, so as to open the pins 102, but at this time, under the action of the first resetting structure 106, the first blocking structure 105 is in a pop-out state against the limiting member 1042 (e.g. the limiting member 1042 is a concave structure, and part of the first blocking structure 105 (e.g. the blocking portion 1054) is inserted into the concave structure to limit the rotation of the rotating shaft) so as to limit the rotation of the rotating shaft, and at the same time, under the action of the second reset mechanism 1092, the second locking member (e.g., the top end of the fixing member 1094) is abutted against the lower end of the rotating shaft 104 to assist in synchronously limiting the rotation of the rotating shaft, so that the pins cannot be opened and normally inserted to conduct the use of strong electricity, which is a safe state, so that when the foldable plug is alone, the folded pins are locked, cannot be opened without violent damage, cannot be normally inserted to conduct the use of strong electricity, and thus the safety and reliability are higher, and the volume of the foldable plug assembly is smaller. In addition, as shown in fig. 7, the first blocking structure 105 further includes an extension portion 1052, which is configured to be inserted into the positive and negative electrode connecting holes 1083 when the foldable plug assembly is not mounted to the device body and the pins are in the folded state, so as to prevent foreign matters from falling into the positive and negative electrode connecting holes 1083, as shown in fig. 6 and 7, thereby avoiding the problem that the normal function of the pin assembly is affected by the falling of the foreign matters, and further providing better user experience.
In another embodiment, the invention also provides a device comprising the foldable plug assembly in the previous embodiment, which may be any device comprising a plug assembly, for example, the device may comprise a charging device, wherein the charging device may comprise a mobile phone charger, an adapter, a mobile power supply, etc.

As shown in fig. 10, the device further includes a device main body 200 detachably mounted with the foldable plug assembly, and in this drawing, only a partial structure of the device main body 200 is shown, wherein a housing of the device main body 200 is formed with a receiving dock (not shown) for mounting the foldable plug assembly 100, a power receiving assembly is provided in the receiving dock, the power receiving assembly being electrically connected to a circuit structure provided in the device main body 200, and an electric power transmitting assembly provided in the foldable plug assembly 100 for transmitting electric power on the pins 102 to the circuit structure when mounted. The device body 200 may be connected to the collapsible plug assembly by snap-fit, ultrasonic weld, or other suitable means.
In one example, as shown in fig. 10 and 11, the device main body 200 is further provided with positive and negative electrodes 201, for example, extending directions of the positive and negative electrodes are parallel to an inserting direction (direction shown by arrow in fig. 11) of the foldable plug assembly 100, when the foldable plug assembly is assembled into the device main body, the positive and negative electrodes 201 are used for unlocking the first locking elements to make the pins rotatably open and fold and retract, for example, as shown in fig. 12 and 14, when the foldable plug assembly is assembled into the device main body (i.e., when the device main body and the foldable plug assembly are in a connected state), the positive and negative electrodes pass through positive and negative connecting holes on the foldable plug assembly to abut against the first locking elements of the foldable plug assembly, and apply a transverse force to the first locking elements (e.g., the blocking portion 1054) to cause the blocking portion 1054 of the first blocking structure 105 abutting against the limiting member 1042 to be separated from the limiting member 1042 to release the limitation on the rotating shaft, to unlock the first locking member to allow the prongs to be rotatably opened and folded for stowage.
Meanwhile, the positive and negative electrodes 201 pass through the positive and negative electrode connecting holes 1083 to be connected with the power transmission assembly in the foldable plug assembly 100 so as to be conducted when the pins are powered on, for example, as shown in fig. 13, the positive and negative electrodes 201 are connected with the conductive elastic sheet 107 so as to be conducted when the pins are powered on. Therefore, the positive and negative electrodes of the device main body can be used for conducting as the electric connection between the positive and negative electrodes and the pin assembly, and can also be used for unlocking the first locking piece to release the limitation on the rotating shaft, so that the pin can be rotatably opened, folded and folded, and the connection reliability between the pin assembly and the device main body can be enhanced.
As shown in fig. 15, the device body 200 includes a fixing portion 202 for engaging with the second locking member of the foldable plug assembly, for example, an end portion of the second locking member protruding from the housing, and optionally, the fixing portion 202 may be disposed at the bottom of the housing of the device body 200, and when the pins are opened, the second locking member (for example, an end portion of the second locking member protruding from the housing) protrudes into the fixing portion 202 under the action of the cam 1041 of the rotation shaft to be coupled with the device body, thereby locking the foldable plug assembly and preventing the foldable plug assembly and the device body from being separated. Under the condition that the pins are opened, the foldable plug assembly is locked with the device body and cannot be separated under the condition of non-violent damage, and the connection is more reliable and safe. When participating in the subassembly and breaking away from the device main part, must fold and pack up to participate in and just can make and participate in subassembly and the separation of device main part, guarantee to participate in to pack up and be convenient for accomodate, user experience is better.
Optionally, as shown in fig. 10, 11, and 14, the fixing position 202 is a groove structure disposed on the device main body, and a portion of the second detent structure 1091 protruding from the housing extends into the groove structure, or the fixing position 202 is a protrusion structure disposed on the device main body, and a groove structure matching the protrusion structure is disposed on the second detent structure 1091 protruding from the housing. Alternatively, other configurations may be used which match each other.
