The number of the conductive spring 107 may be determined according to the number of the pins 102, for example, when the pins 102 are two, the number of the conductive spring 107 is also two, and a general plug assembly has two pins, and the two pins are respectively connected to the live wire or the neutral wire, so that the number of the conductive spring is two.

In one example, as shown in fig. 2 and 3, the locking member includes a detent structure 105, the detent structure 105 is movably disposed in the accommodating space of the housing, and further disposed on the bottom shell 108, and is used for limiting the pivot shaft to swing open the pins when the pins are in the folded state.

Optionally, the locking structure 105 is located below the rotation shaft 1041, and limits the rotation shaft 1041 to rotate to open the plug 102 when the plug is in the folded state.

For example, the locking structure 105 can be moved in a direction perpendicular to the axial direction of the rotation shaft 1041 to move the locking structure 105 toward or away from the rotation shaft.

Illustratively, when the prongs are folded, the retaining structure 105 abuts against the stop 1042 to limit the rotation of the rotation shaft.

The detent structure 105 may be disposed on the bottom shell 108 between the adjacent brackets 1082, and in order to limit the moving direction of the locking member, a sliding slot (not shown) may be disposed on the bottom shell 108, and the detent structure 105 is disposed in the sliding slot and moves along the length extension direction of the sliding slot. Optionally, the detent structure 105 extends from the detent structure main body and extends out of the housing through the mounting hole 1083, that is, a part of the detent structure 105 extends from the detent structure main body and extends out of the housing through the mounting hole 1083, or the detent structure 105 is opposite to the mounting hole 1083 and is located outside the mounting hole 1083.

The detent structure 105 may be formed in a suitable shape, such as a square column or the like, or other irregular shapes, as desired, but it is desirable that the surface of the detent structure 105 contacting the bottom case be formed flat to facilitate movement of the locking member.

Specifically, the fixed end abuts against the sidewall of the panel 101 or the sidewall of the bottom case 108 according to the actual structure of the two, if the panel 101 has a downwardly-suspended sidewall and the bottom case 108 is fastened to the bottom end of the sidewall, the fixed end of the reset structure 106 abuts against the sidewall of the panel 101, and if the bottom case has an upwardly-protruded sidewall and is fastened to the panel, the fixed end of the reset structure 106 may abut against the sidewall of the bottom case 108.

When the locking structure 105 is located under the rotation shaft 1041, the restoring structure can be in a compressed state or in a natural extended state, so that the locking structure 105 can move under the rotation shaft 1041 under the elastic force of the restoring structure until the locking structure is no longer moved.

Illustratively, the reset mechanism 106 includes a reset spring, wherein one end of the detent mechanism 105 connected to the reset mechanism has a protrusion 1051, and a free end of the reset spring is connected to the protrusion, for example, the free end of the reset spring is sleeved on the protrusion 1051, so as to connect the reset mechanism 106 and the detent mechanism 105.

As shown in fig. 3, when the foldable plug assembly is not connected to the device body, the front shell 101 and the bottom shell 108 are firmly combined and can be regarded as an integral non-detachable member, and no relative displacement occurs, at this time, the pins 102 are kept in the folded and retracted state, i.e. the locked state, if the pins 102 are to be opened, the rotating shaft 1041 needs to be rotated 90 ° in the counterclockwise direction indicated by the arrow 1 in the drawing to open the pins 102, but at this time, under the action of the reset structure 106, the locking structure 105 keeps the ejected state and is located below the rotating shaft 1041, and the rotating shaft 1041 rotates to generate a tangential force which does not move the locking member, the locking member acts on the rotating shaft 1041 to rotate, so that the pins cannot be opened and cannot be normally inserted into a strong current conducting use, which is in this time, the safety state is obtained, so that when the foldable plug alone exists, the folded pins are, the foldable plug assembly can not be opened under the condition of non-violent damage, can not be normally plugged into a strong electric appliance, so that the safety and the reliability are higher, and the volume of the foldable plug assembly is smaller.

In another embodiment, the present invention also provides a device comprising the foldable plug assembly of the previous embodiments, 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.

Specifically, in one example, as shown in fig. 4, the device 200 of the present invention including a foldable plug assembly, the device 200 includes: the foldable plug assembly 100 previously described includes a face housing 101, pins 102, etc.

The device 200 further comprises a device body 201, only part of the structure of the device body 201 being shown in the drawing, wherein the housing of the device body 201 is formed with a receiving portion Wu for mounting the foldable plug assembly 100, a power receiving assembly is provided in the receiving bay, the power receiving assembly being electrically connected to a circuit structure provided in the device body 201, and when mounted, to a power transmitting assembly provided in the foldable plug assembly 100 for transmitting power on the pins 102 to the circuit structure. The device body 201 may be connected to the collapsible plug assembly by snap-fit connection, snap-fit clamping, ultrasonic welding, or other suitable means.

In one specific example, as shown in fig. 5, the device body 201 is detachably mounted with the foldable plug assembly, wherein the device body 201 includes an unlocking structure 202 for unlocking the lock to allow the prongs to be rotatably opened and folded for stowage when the foldable plug assembly is assembled into the device body.

Illustratively, when the foldable plug assembly is assembled into the device body, one end of the unlocking structure 202 abuts against the latching structure 105 of the foldable plug assembly, so that the latching structure 105 moves out of the position below the pivot axis 1041 of the foldable plug assembly to release the restriction of the pivot axis, and the pins can be rotated to open and folded to retract.

As shown in fig. 5, when the foldable plug assembly is assembled and connected with the device body, the unlocking structure passes through the mounting hole on the foldable plug assembly and abuts against the locking piece of the foldable plug assembly, so that the locking piece is unlocked, and the pins can be rotatably opened and folded for storage.

Specifically, the bottom housing of the foldable plug assembly further includes a vertically disposed mounting plate, a mounting hole is disposed on the mounting plate opposite to an end of the locking member of the foldable plug assembly, the unlocking structure 202 of the device body 201 passes through the mounting hole disposed on the bottom housing 108 and the gap between the brackets on the bottom housing 108 to apply a force on the locking structure 105, the force makes the locking structure 105 overcome the elastic force of the reset structure 106 to work and move in a direction away from the rotation shaft 1041 until the device body 201 and the foldable plug assembly are completely mounted in place, and the locking member is away from the rotation shaft 1041 at this time, so as to remove the limitation on the rotation shaft 1041, so that the rotation shaft 1041 can rotate in the accommodating space enclosed by the front housing and the bottom housing, and the plug pins 102 can be folded and retracted or opened.

As shown in fig. 6, when the user uses the device, the locking structure 105 does not restrict the rotation shaft 1041, so that the pin 102 can be directly applied with force to open the device, thereby electrically connecting the device 200 with a power source.

In one example, as shown in fig. 6, the top of the unlocking structure 202 is further provided with a groove 203, when the foldable plug assembly is in the open state, a stopper 1042 of the foldable plug assembly abuts against an inner wall of the groove 203, and an acting force is applied between the stopper and the unlocking structure, so that the foldable plug assembly cannot be separated from the device body when the pins are opened.

The unlocking structure 202 may be a structure disposed on the housing of the device body, when the pins 102 of the foldable plug assembly are opened, the grooves 203 are disposed to avoid the interference with the retaining members 1042, and once the pins 102 are fully opened, the retaining members 1042 are disposed in the grooves and may further abut against the sidewalls of the grooves, or may not abut against the sidewalls of the grooves.

Alternatively, the size and shape of the groove 203 may be set reasonably according to actual needs, for example, it may be a square groove, etc., and is not limited specifically herein.

Because the limiting member is located in the groove, a user cannot separate the foldable plug assembly from the device body when the pins 102 are in an opened state, and the foldable plug assembly needs to be separated from the device body only by retracting the pins.

In the process state that the foldable plug assembly and the device body are separated by assembling, i.e. from unlocking to locking state, the pins 102 of the foldable plug assembly are in the opening state initially, and the plug assembly and the device body cannot be separated under the action of the unlocking structure of the device body, therefore, as shown in fig. 7, when the plug assembly is separated from the device body, the pins must be folded and retracted, the pins can be forcibly rotated and folded through the unlocking structure or manually folded and retracted, the foldable plug assembly can be separated from the device body, otherwise, the pins cannot be separated under the action of the unlocking structure of the device body, after the pins are folded and retracted, the plug assembly and the device body can be separated, under the elastic force of the resetting structure, the blocking structure 105 is restored below the rotating shaft 1041 to realize locking state, and then the state shown in fig. 3 is restored, the locking member locks the prongs against pivotal opening.

The device comprising the foldable plug assembly of the utility model comprises the foldable plug assembly and a device main body, wherein the device main body is detachably connected with the foldable plug assembly, the device main body comprises an unlocking structure, when the foldable plug assembly is assembled into the device main body, one end of the unlocking structure is abutted against a locking piece of the foldable plug assembly, so that the locking piece moves out of the lower part of a revolving shaft of the foldable plug assembly to remove the limitation on the revolving shaft, thereby enabling the pins to be normally folded, folded or unfolded, and ensuring the normal use of the device; when the plug assembly is separated from the device main body, the plug pins must be folded and retracted, otherwise, the plug assembly cannot be separated under the action of an unlocking structure of the device main body; after the foldable plug assembly is separated from the device body, the pins are in a folding locking state, and cannot be opened under normal operation and cannot be normally inserted into a strong current for use, so that the safety and the reliability are higher. In addition, the foldable plug design is more convenient for the user to carry, and the user experience is better.
