[0036] With the development of new energy electric vehicles, the popularity rate of electric vehicles is getting higher and higher, and the demand for charging equipment is increasing continuously. There are many specifications for existing charging plugs. For example, in the national standard size of three-prong plugs, there are two specifications of 16A and 10A. As a charging device that comes with the vehicle, the mode 2 AC charging gun can directly charge using the AC power grid, which is extremely convenient. However, due to the differences in the sizes of the two specifications of 16A and 10A in the national standard size of three-prong plugs, they are not compatible during use, greatly limiting the scope of use of the charging gun.

[0037] In view of this, the present utility model proposes a plug 100. By respectively arranging a first plug-in part 21 and a second plug-in part 22 on the relatively arranged first surface 11 and second surface 12 of the plug 100 housing 1, and by using a switching part 3 to switch the conduction between the cable and the first plug-in part 21 or the conduction between the cable and the second plug-in part 22, the requirement that the same plug 100 adapts to different specifications of sockets is achieved.

[0038] To better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings.

[0039] As Figure 1-10As described above, a plug 100 provided by an embodiment of the present utility model includes a housing 1. A cavity 10 is provided inside the housing 1. The housing 1 has a first surface 11 and a second surface 12 that are oppositely arranged, and the first surface 11, the second surface 12 are perpendicular to the insertion direction; a plugging component 2, the plugging component 2 includes a plurality of first plugging members 21 and a plurality of second plugging members 22. The first plugging members 21 are arranged on the first surface 11. One end of the first plugging member 21 extends out of the first surface 11 to form a first plugging portion 211, and the other end of the first plugging member 21 extends into the cavity 10 to form a first conduction portion 212; the second plugging members 22 are arranged on the second surface 12. One end of the second plugging member 22 extends out of the second surface 12 to form a second plugging portion 221, and the other end of the second plugging member 22 extends into the cavity 10 to form a second conduction portion 222; a switching member 3, the switching member 3 has a control member 31 and a conductive member 32. The control member 31 controls the conductive member 32 to switch between a first position and a second position. When the conductive member 32 is in the first position, the first conduction portion 212 is electrically connected to the conductive member 32, and when in the second position, the second conduction portion 222 is connected to the conductive member 32.

[0040] In the technical solution adopted in this embodiment, the plug 100 has a housing 1. It can be understood that, in order to ensure safety and prevent electric shock, the housing 1 is often an insulating housing. A cavity 10 is provided inside the housing 1. The housing 1 has a first surface 11 and a second surface 12 which are oppositely arranged, and the first surface 11, the second surface 12 are perpendicular to the insertion direction. A plurality of first connectors 21 are provided on the first surface 11, and a plurality of second connectors 22 are provided on the second surface 12. It can be understood that the plurality of first connectors 21 on the first surface 11 can have a certain specification distribution method, and the second connectors 22 on the second surface 12 can have another specification distribution method. Preferably, the distribution method of the plurality of first connectors 21 is a 16A three-pin plug, and the distribution method of the plurality of second connectors 22 is a 10A three-pin plug. One end of the first connector 21 extends out of the first surface 11 to form a first insertion portion 211, and the first insertion portion 211 is used for inserting into a socket of a corresponding specification. For example, the first insertion portion 211 can be inserted into a 16A socket. The other end of the first connector 21 extends into the cavity 10 to form a first conduction portion 212. One end of the second connector 22 extends out of the second surface 12 to form a second insertion portion 221, and the second insertion portion 221 is used for inserting into a socket of another specification. For example, the second insertion portion 221 can be inserted into a 10A socket. The other end of the second connector 22 extends into the cavity 10 to form a second conduction portion 222. The switching member 3 has a control member 31 and a conductive member 32. The control member 31 controls the conductive member 32 to switch between a first position and a second position. When the conductive member 32 is in the first position, the first conduction portion 212 and the conductive member 32 are electrically connected. When in the second position, the second conduction portion 222 and the conductive member 32 are connected. It can be understood that when the control member 31 controls the conductive member 32 to be in the first position, at this time the conductive member 32 is electrically connected to the first conduction portion 212 of the first connector 21. When the first insertion portion 211 of the first connector 21 is inserted into a socket of a corresponding specification, the electric energy in the socket is transmitted to the first insertion portion 211 and then to the conductive member 32, and then is transmitted to a corresponding device such as a charging gun 300 through a first cable 500 connected to the conductive member 32, thereby completing the transmission of electric energy. When the control member 31 controls the conductive member 32 to be in the second position, at this time the conductive member 32 is electrically connected to the second conduction portion 222 of the second connector 22. When the second insertion portion 221 of the second connector 22 is inserted into a socket of a corresponding specification, the electric energy in the socket is transmitted to the conductive member 32 through the second insertion portion 221, and then is transmitted to a corresponding device such as a charging gun 300 through a first cable 500 connected to the conductive member 32, thereby completing the transmission of electric energy.By respectively arranging a plurality of first plug connectors 21 and a plurality of second plug connectors 22 on different surfaces of the housing 1, and at the same time arranging a switching member 3 to conduct electricity between the conductive member 32 and one of the first plug connector 21 and the second plug connector 22 to achieve power transmission, preventing the first plug connector 21 and the second plug connector 22 from being simultaneously connected to the conductive member 32 to cause potential safety hazards.

[0041] It can be understood that the switching member 3 can be switched between the first position and the second position by translating along the plugging direction. For example, when the switching member 3 as a whole moves closer to the position of the first plugging portion 211, at this time the switching member 3 is in the first position, the conductive member 32 is connected to the first conducting portion 212, and at the same time the conductive member 32 is far away from and not connected to the second conducting portion 222, so that the conductive member 32 is only connected to the first plug connector 21. When the plugging member as a whole moves closer to the position of the second plugging portion 221, at this time the switching member 3 is in the second position, the conductive member 32 is connected to the second conducting portion 222, and at the same time the conductive member 32 is far away from and not connected to the first conducting portion 212, so that the conductive member 32 is only connected to the second plug connector 22. The switching member 3 can also be switched between the first position and the second position in other ways, such as buttons, knobs, etc., which are not limited one by one here.

[0042] Furthermore, in an embodiment of the present utility model, the housing 1 further includes a first side surface 13 and a second side surface 14 arranged opposite to each other. A through hole 131 communicating with the cavity 10 is provided on the first side surface 13. The control member 31 includes a rotating rod 311 and a knob 312. The rotating rod 311 is arranged in the cavity 10. One end of the rotating rod 311 is rotatably connected to the second side surface 14, and the other end of the rotating rod 311 passes through the through hole 131 and is connected to the knob 312; when the knob 312 is rotated, the knob 312 drives the conductive member 32 to be switched between the first position and the second position.

[0043] It can be understood that the housing 1 further has a bottom surface 19, and a wire passing hole 191 is provided on the bottom surface 19. One end of the first cable 500 passes through the wire passing hole 191 to be electrically connected to the conductive member 32. The housing 1 further includes a first side surface 13 and a second side surface 14 which are oppositely arranged. A through hole 131 communicating with the cavity 10 is provided on the first side surface 13. One end of the rotating rod 311 passes through the cavity 10 and is rotatably connected to the second side surface 14. The other end of the rotating rod 311 passes through the through hole 131 and is connected to the knob 312. It can be understood that there are various ways to rotatably connect one end of the rotating rod 311 to the second side surface 14. For example, a through hole can be provided at a position corresponding to the through hole 131 on the second side surface 14, and the end of the rotating rod 311 away from the knob 312 passes through the through hole, so that the rotating rod 311 can rotate around the axes of the through hole 131 and the through hole; or a notch can be provided at a position corresponding to the through hole 131 on the second side surface 14, and the diameter of the notch is equivalent to the diameter of the rotating rod 311. The end of the rotating rod 311 away from the knob 312 is limited in the notch, so that the rotating rod 311 can rotate around the axes of the notch and the through hole 131. It can be understood that the rotating rod 311 can also be rotatably connected to the second side surface 14 in other ways, which is not limited here. When the knob 312 is rotated, the knob 312 drives the conductive member 32 to rotate around the axis of the rotating rod 311, so that the conductive member 32 can be switched between the first position and the second position.

[0044] Further, in an embodiment of the present invention, the rotating rod 311 further includes a connecting portion 3112, and the connecting portion 3112 is located in the middle of the length of the rotating rod 311. The conductive member 32 is vertically penetrated through the connecting portion 3112.

[0045] It can be understood that the rotating rod 311 further includes a connecting portion 3112, and the connecting portion 3112 is located at the middle position in the length direction of the rotating rod 311. Preferably, the conductive member 32 is vertically penetrated through the connecting portion 3112. Optionally, the cross section of the connecting portion 3112 is square. With such a setting, when the conductive member 32 is penetrated through the connecting portion 3112, the contact area between the two can be increased, and the connection stability between the conductive member 32 and the connecting portion 3112 can be improved.

[0046] Further, in an embodiment of the present invention, the number of the conductive members 32 is multiple, and the multiple conductive members 32 are sequentially arranged at intervals along the axial direction of the rotating rod 311. Each conductive member 32 includes a wiring portion 321 and a conduction rod 323 which are connected to each other. The wiring portion 321 is located at the end of the conductive member 32 away from the plugging assembly 2. The wiring portion 321 is connected to a wire, and the conduction rod 323 can be connected to the first conduction portion 212 or the second conduction portion 222.

[0047] It can be understood that the number of the conductive members 32 is multiple, and the multiple conductive members 32 are sequentially arranged at intervals along the axial direction of the rotating rod 311, so that the multiple conductive members 32 are respectively conductively connected to the multiple first plug connectors 21 or the multiple second plug connectors 22. To prevent short circuits between the multiple conductive members 32, the multiple conductive members 32 are sequentially arranged at intervals along the axial direction of the rotating rod 311. Each conductive member 32 includes a wiring portion 321 and a conduction rod 323 which are connected to each other. The wiring portion 321 is located at one end of the conductive member 32 away from the plugging assembly 2. The wiring portion 321 is connected to the first cable 500, and the conduction rod 323 can be connected to the first conduction portion 212 or the second conduction portion 222. With such an arrangement, when the first plug connector 21 is plugged in according to the corresponding specification, the electric energy in the socket is transmitted to the conductive member 32 connected thereto through the first plug connector 21, and the electric energy is transmitted to the first cable 500 connected to the wiring portion 321 through the wiring portion 321 of the conductive member 32, thereby realizing energy transmission. Preferably, in order to ensure that short circuits do not occur between different conductive members 32, the connecting portion 3112 is made of an insulating material.

[0048] Further, in an embodiment of the present invention, at least one conductive member 32 further includes a conduction head 322. The conduction head 322 is arranged at one end of the conduction rod 323 away from the wiring portion 321. The conduction head 322 includes a first conduction sheet 3221 and a second conduction sheet 3222 which are arranged in parallel at intervals. A first conduction groove 3223 is provided between the first conduction sheet 3221 and the second conduction sheet 3222.

[0049] It can be understood that as Figure 7 、 9 shown, in order to make the contact between the conductive member 32 and the plugging assembly 2 more stable, at least one conductive member 32 further includes a conduction head 322. The conduction head 322 is arranged at one end of the conduction rod 323 away from the wiring portion 321. The conduction head 322 includes a first conduction sheet 3221 and a second conduction sheet 3222 which are arranged in parallel at intervals. A first conduction groove 3223 is provided between the first conduction sheet 3221 and the second conduction sheet 3222. With such an arrangement, the first conduction portion 212 or the second conduction portion 222 can be inserted into the first conduction groove 3223, thereby increasing the contact area and ensuring the stability of the contact. Preferably, when the conductive member 32 includes the conduction head 322, the first conduction portion 212 or the second conduction portion 222 connected to the conductive member 32 is a conductive sheet, and the thickness of the conductive sheet is equivalent to the thickness of the first conduction groove 3223, so as to ensure that the conductive sheet can be inserted into the first conduction groove 3223.

[0050] Further, in an embodiment of the present utility model, at least one of the first conduction portions 212 includes a first connection piece and the second connection piece arranged in parallel, and a first connection groove is provided between the first connection piece and the second connection piece; and / or, at least one of the second conduction portions 222 includes a third connection piece 2221 and a fourth connection piece 2222 arranged in parallel, and a second connection groove 2223 is provided between the third connection piece 2221 and the fourth connection piece 2222.

[0051] It can be understood that, as Figure 2-3 shown, in order to make the contact between the conductive member 32 and the plugging assembly 2 more stable, at least one of the first conduction portions 212 includes a first connection piece and the second connection piece arranged in parallel, and a first connection groove is provided between the first connection piece and the second connection piece; and / or, at least one of the second conduction portions 222 includes a third connection piece 2221 and a fourth connection piece 2222 arranged in parallel, and a second connection groove 2223 is provided between the third connection piece 2221 and the fourth connection piece 2222. With such a setting, when the conductive member 32 does not include the conduction head 322, the conduction rod 323 of the conductive member 32 can be inserted into the first connection groove or the second connection groove 2223, so as to increase the contact area and ensure the stability of the contact. Preferably, when the first conduction portion 212 includes the first connection groove and / or the second conduction portion 222 includes the second connection groove 2223, the conduction rod 323 of the corresponding conductive member 32 is sheet-shaped, and the thickness of the conduction rod 323 is equivalent to the thickness of the first connection groove and / or the second connection groove 2223, so as to ensure that the conduction rod 323 can be inserted into the first connection groove and / or the second connection groove 2223.

[0052] Further, in an embodiment of the present utility model, the housing 1 includes a first outer shell 17 and a second outer shell 18, the first surface 11 is located on the first outer shell 17, the second surface 12 is located on the second outer shell 18, and the first outer shell 17 and the second outer shell 18 enclose to form the cavity 10.

[0053] It can be understood that the housing 1 can be made in an integrally formed manner. Preferably, for the convenience of assembling each component, it can also be made into a split type. It can be understood that the housing 1 includes a first outer shell 17 and a second outer shell 18, the first surface 11 is located on the first outer shell 17, the second surface 12 is located on the second outer shell 18, and the first outer shell 17 and the second outer shell 18 enclose to form the cavity 10.

[0054] Furthermore, in one embodiment of the present invention, a stop ring 15 is protruding from the side of the second side 14 facing the inner cavity, and a rotation groove is formed by the stop ring 15 and the inner wall of the second side 14. The end of the rotating rod 311 away from the knob 312 is inserted into the rotation groove, and a yield groove 16 is provided on the stop ring 15. A stop protrusion 3111 is provided on the side of the rotating rod 311 away from the knob 312, and the stop protrusion 3111 rotates in the yield groove 16.

[0055] It is understood that in order to ensure the stability of the rotation of the rotating rod 311, a stop ring 15 is provided on the side of the second side 14 facing the inner cavity. The stop ring 15 and the inner wall of the second side 14 form a rotation groove, and the end of the rotating rod 311 away from the knob 312 is inserted into the rotation groove. The through hole 131 and the rotation groove limit the rotating rod 311 to always rotate around the axis. In order to allow the switching member 3 to move between specific angles, a clearance groove 16 is provided on the stop ring 15.

By providing a clearance groove 16 on the stop ring 15, the clearance groove 16 limits the movement of the stop protrusion 3111, and then limits the rotation angle of the rotating rod 311, thereby preventing the switching member 3 from rotating too large an angle in the cavity 10 and causing damage to the components in the cavity 10, the first conductive part 212, and the second conductive part 222.

[0056] Preferably, a limiting ring 3113 is provided on the side of the rotating rod 311 near the knob 312. A limiting groove 3114 is provided between the limiting ring 3113 and the knob 312. The diameter of the limiting ring 3113 is larger than the diameter of the through hole 131. During installation, the end of the rotating rod 311 away from the knob 312 is inserted into the rotating groove, and the wall of the through hole 131 is engaged with the limiting groove 3114. This prevents the rotating rod 311 from axial displacement, thus ensuring the stability of the overall structure.

[0057] like Figure 10 As shown, an embodiment of the present invention also proposes a portable charging pile, which includes a charging gun 300, a first cable 500, a control box 200, a second cable 400 and a plug 100 as described above, wherein the charging gun 300 is connected to the control box 200 through the first cable 500, and the control box 200 is connected to the plug 100 through the second cable 400.

[0058] It can be understood that the charging gun 300 and the plug 100 are connected through a connecting component. Preferably, the connecting component includes a first cable 500, a control box 200, and a second cable 400. When the plug 100 needs to be plugged into a socket of the same specification as the second plug-in member 22 on the second surface 12, such as a 10A socket, select the 10A charging mode on the control box 200. At the plug 100 end, rotate the control member 31 towards the second surface 12 so that the conductive member 32 contacts the second conduction part 222. Similarly, when the plug 100 needs to be plugged into a socket of the same specification as the first plug-in member 21 on the first surface 11, such as a 16A socket, select the 16A charging mode on the control box 200. At the plug 100 end, rotate the control member 31 towards the first surface 11 so that the conductive member 32 contacts the second conduction part 222. Since the plug 100 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0059] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
