[0037] With the development of new energy electric vehicles, the popularity of electric vehicles is getting higher and higher, and the demand for charging equipment is increasing. There are many specifications of existing charging plugs. For example, in the national standard size of three plugs, there are two specifications of 16A and 10A. Mode 2 AC charging gun, as a charging device on the vehicle, can be directly charged using the AC power grid, which is extremely convenient. However, due to the difference in the size of the two specifications of 16A and 10A in the national standard size of three plugs, they are not compatible during use, which greatly limits the scope of use of the charging gun.

[0038] In view of this, the utility model proposes a plug 3, by simultaneously arranging a first connector 331 and a second connector 332 on a plug housing 31, and controlling the first connector 331 and the second connector 332 to extend out of or enter a through hole 3111 through a control component 34, so as to meet the requirements of sockets of different specifications.

[0039] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0040] like Figure 1-6 The plug 3 proposed in the embodiment of the utility model includes a shell 31, a cavity 32 is provided in the shell 31, the shell 31 has a first surface 311 and a second surface 312 adjacent to each other, the first surface 311 is perpendicular to the plug-in direction; a first plug-in component 33, the first plug-in component 33 includes a first plug-in part 331 and a second plug-in part 332 arranged at intervals, the first plug-in component 33 is arranged in the cavity 32, the first surface 311 is provided with a through hole 3111 corresponding to the first plug-in component 33; a control component 34, the control component 34 is arranged on the second surface 31 2, the control assembly 34 includes a first control member 341 and a second control member 342 that are spaced apart, a first sliding hole 351 and a second sliding hole 352 are provided on the second surface 312, one end of the first control member 341 extends into the first sliding hole 351 and is fixedly connected to the first connector 331, and one end of the second control member 342 extends into the second sliding hole 352 and is fixedly connected to the second connector 332; the control assembly 34 slides along the plugging direction to drive the first connector 331 and / or the second connector 332 to extend out of or enter the through hole 3111.

[0041] In the technical solution adopted in this embodiment, the plug 3 has a shell 31. It is understandable that in order to ensure safety and prevent electric shock, the shell 31 is often an insulating shell 31. A cavity 32 is provided in the shell 31, and a first plug component 33 is provided in the cavity 32. It is understandable that the first surface 311 is perpendicular to the plug-in direction. When the plug 3 is plugged into the socket, the first surface 311 of the shell 31 faces the socket. Preferably, the second surface 312 is adjacent to the first surface 311. The first plug component 33 is arranged in the cavity 32, and the first surface 311 is provided with a through hole 3111 corresponding to the first plug component 33. One end of the first plug component 33 can be connected to the live wire and / or the neutral wire, and the other end of the first plug component 33 can extend from the first surface 311 through the through hole 3111, so as to be plugged into the socket to transmit the electrical energy in the socket. The first plug component 33 includes a first plug connector 331 and a second plug connector 332 arranged at intervals. The control assembly 34 is arranged on the second surface 312, and includes a first control member 341 and a second control member 342 arranged at intervals. The second surface 312 is provided with a first sliding hole 351 and a second sliding hole 352. The first sliding hole 351 and the second sliding hole 352 are both connected to the cavity 32. One end of the first control member 341 extends into the first sliding hole 351 and is fixedly connected to the first plug-in member 331, and one end of the second control member 342 extends into the second sliding hole 352 and is fixedly connected to the second plug-in member 332; the control assembly 34 slides along the plug-in direction to drive the first plug-in member 331 and / or the second plug-in member 332 to extend out of or enter the through hole 3111. It can be understood that when the socket is adapted to the size of the first control member 341, the first control member 341 can be operated to make the first control member 341 slide in the first sliding hole 351 in a direction close to the first surface 311, thereby driving the first plug-in member 331 to extend out of the through hole 3111, and at the same time, the second control member 342 is operated to make the second control member 342 slide in the second sliding hole 352 in a direction away from the first surface 311, thereby driving the second plug-in member 332 to enter the through hole 3111, so that the first control member 341 and the socket can be connected. When the socket is adapted to the size of the second control member 342, the first control member 341 can be operated to make the first control member 341 slide in the first sliding hole 351 in a direction away from the first surface 311, thereby driving the first plug-in member 331 to enter the through hole 3111, and at the same time, the second control member 342 can be operated to make the second control member 342 slide in the second sliding hole 352 in a direction close to the first surface 311, thereby driving the second plug-in member 332 to extend out of the through hole 3111, so that the second control member 342 and the socket can be plugged. In this way, the plug 3 can control the positions of the first plug-in member 331 and the second plug-in member 332 through the control component 34, so as to match and adapt to charging sockets of different specifications.

[0042] Furthermore, in an embodiment of the present invention, the plug 3 further includes a second plug assembly 36 , and the second plug assembly 36 includes a fifth plug piece, and the fifth plug piece is fixedly connected to the housing 31 .

[0043] It can be understood that the fifth plug-in piece passes through the first surface 311 and is fixedly connected to the housing 31. Preferably, one end of the fifth plug-in piece is exposed from the first surface 311 so as to be plugged into the socket, and the other end of the fifth plug-in piece is connected to the ground wire.

[0044] Furthermore, in one embodiment of the utility model, the first connector 331 includes a first connector piece 3311 and a second connector piece 3312, and the first connector piece 3311 and the second connector piece 3312 are symmetrical about the central axis; the second connector 332 includes a third connector piece 3321 and a fourth connector piece 3322, and the first connector piece 3311 and the third connector piece 3321 are parallel and spaced apart, and the second connector piece 3312 and the fourth connector piece 3322 are parallel and spaced apart.

[0045] It can be understood that such a configuration ensures that the first connector 331 and the second connector 332 will not interfere with each other when moving along the plugging direction, and also enables the first connector 331 to adapt to one socket specification and the second connector 332 to adapt to another socket specification.

[0046] Preferably, the distance between the first connector 331 and the center of the socket is smaller than the distance between the second connector 332 and the center of the socket. It can be understood that such a configuration can enable the first connector 331 to adapt to, for example, a 10A socket, and the second connector 332 to adapt to, for example, a 16A socket.

[0047] Furthermore, in an embodiment of the present invention, the fifth plug-in piece is electrically connected to the ground wire, the first plug-in piece 3311 and the third plug-in piece 3321 are electrically connected to the live wire, and the second plug-in piece 3312 and the fourth plug-in piece 3322 are electrically connected to the neutral wire.

[0048] It can be understood that in the national standard size of three sockets, the 10A socket has three plug holes, and the three plug holes are respectively connected to the ground wire, the live wire, and the neutral wire. Similarly, the 16A socket also has three plug holes, which are also respectively connected to the ground wire, the live wire, and the neutral wire. In order to make the plug 3 applicable to both the 10A socket and the 16A socket, the plug 3 in the utility model is provided with a first plug piece 3311, a second plug piece 3312, a third plug piece 3321, a fourth plug piece 3322 and a fifth plug piece, wherein the fifth plug piece is fixedly connected to the housing 31, and the fifth plug piece is connected to the ground wire. The first plug piece 3311 and the third plug piece 3321 are electrically connected to the live wire, and the second plug piece 3312 and the fourth plug piece 3322 are electrically connected to the neutral wire. Thus, when the first plug-in connector 331 extends out of the through hole 3111 and the second plug-in connector 332 enters the through hole 3111, the first plug-in connector 3311, the second plug-in connector 3312, and the fifth plug-in connector are connected to the socket, the fifth plug-in connector is connected to the ground wire, the first plug-in connector 3311 is connected to the live wire, and the second plug-in connector 3312 is connected to the neutral wire, so that the 10A socket can supply power to the plug 3. When the second plug-in connector 332 extends out of the through hole 3111 and the first plug-in connector 331 enters the through hole 3111, the third plug-in connector 3321, the fourth plug-in connector 3322, and the fifth plug-in connector are connected to the socket, the fifth plug-in connector is connected to the ground wire, the third plug-in connector 3321 is connected to the live wire, and the fourth plug-in connector 3322 is connected to the neutral wire, so that the 16A socket can supply power to the plug 3.

[0049] Further, in one embodiment of the utility model, the through hole 3111 includes a first sub-hole, a second sub-hole, a third sub-hole and a fourth sub-hole, the first sub-hole and the first plug-in piece 3311 are arranged correspondingly, the second sub-hole and the second plug-in piece 3312 are arranged correspondingly, the third sub-hole and the third plug-in piece 3321 are arranged correspondingly, and the fourth sub-hole and the fourth plug-in piece 3322 are arranged correspondingly.

[0050] It can be understood that by setting the first sub-hole, the second sub-hole, the third sub-hole and the fourth sub-hole on the first surface 311 corresponding to the first plug-in piece 3311, the second plug-in piece 3312, the third plug-in piece 3321 and the fourth plug-in piece 3322, the first plug-in piece 331 and the second plug-in piece 332 can be smoothly extended or entered into the through hole 3111, and the first plug-in piece 3311, the second plug-in piece 3312, the third plug-in piece 3321 and the fourth plug-in piece 3322 can be limited by the hole walls of the first sub-hole, the second sub-hole, the third sub-hole and the fourth sub-hole to prevent the first plug-in piece 3311, the second plug-in piece 3312, the third plug-in piece 3321 and the fourth plug-in piece 3322 from shaking in the radial direction, thereby improving the stability of the plug 3.

[0051] Furthermore, in one embodiment of the utility model, the first control member 341 includes a first lever 3411 and a first connecting rod, and the end of the first lever 3411 facing the shell 31 is connected to the first connector 331 through the first connecting rod; the second control member 342 includes a second lever 3421 and a second connecting rod, and the end of the second lever 3421 facing the shell 31 is connected to the second connector 332 through the second connecting rod.

[0052] It can be understood that the first control member 341 includes a first lever 3411 and a first connecting rod, and the end of the first lever 3411 facing the housing 31 is connected to the first connector 331 through the first connecting rod, so that the movement of the first lever 3411 can drive the movement of the first connector 331. The second control member 342 includes a second lever 3421 and a second connecting rod, and the end of the second lever 3421 facing the housing 31 is connected to the second connector 332 through the second connecting rod, so that the movement of the second lever 3421 can drive the movement of the second connector 332. Preferably, the width of the first lever 3411 is greater than the width of the first sliding hole 351, and the width of the second lever 3421 is greater than the width of the second sliding hole 352. It can be understood that by making the width of the first lever 3411 greater than the width of the first sliding hole 351, the first lever 3411 will not enter the first sliding hole 351, and the second lever 3421 will not enter the second sliding hole 352, thereby improving the stability of the control component 34 moving along the plugging direction.

[0053] Furthermore, in an embodiment of the present invention, a first limiting portion 313 is provided at one end of the first sliding hole 351 and / or the second sliding hole 352 close to the first surface 311 , and a second limiting portion 314 is provided at one end of the first sliding hole 351 and / or the second sliding hole 352 away from the first surface 311 .

[0054] It can be understood that a first limiting portion 313 is provided at one end of the first sliding hole 351 close to the first surface 311, and a second limiting portion 314 is provided at one end of the first sliding hole 351 away from the first surface 311; similarly, a first limiting portion 313 is provided at one end of the second sliding hole 352 close to the first surface 311, and a second limiting portion 314 is provided at one end of the second sliding hole 352 away from the first surface 311. When the plug 3 needs to be matched with a 10A socket, the first lever 3411 is pushed in a direction close to the first surface 311 until it exceeds the first limiting portion 313, and the second lever 3421 is pushed in a direction away from the first surface 311 until it exceeds the second limiting portion 314, so that the first plug-in piece 3311 extends out of the first sub-hole and the second plug-in piece 3312 extends out of the second sub-hole, the first limiting portion 313 clamps the first control member 341, and at the same time, the third plug-in piece 3321 enters the third sub-hole and the fourth plug-in piece 3322 enters the fourth sub-hole, and the second limiting portion 314 clamps the second control member 342, thereby preventing the first plug-in piece 3311 and the second plug-in piece 3312 from being erroneously retracted into the through hole 3111, and the third plug-in piece 3321 and the fourth plug-in piece 3322 from being erroneously extended out of the through hole 3111, causing connection failure.

[0055] Further, in one embodiment of the utility model, the first sliding hole 351 and / or the second sliding hole 352 have a first long side and a second long side that are arranged opposite to each other; the first limiting portion 313 is two protrusions that are arranged opposite to each other on the first long side and the second long side; and / or the second limiting portion 314 is two protrusions that are arranged opposite to each other on the first long side and the second long side.

[0056] It can be understood that a portion of the first connecting rod slides in the first sliding hole 351, and the width of the portion is less than the distance between the first long side and the second long side of the first sliding hole 351, and is greater than the distance between the two oppositely arranged protrusions. In this way, when the first control member 341 slides in the first sliding hole 351 along the plugging direction, an external force must be applied to enable the first connecting rod to pass through the first limiting portion 313 and the second limiting portion 314. Similarly, a portion of the second connecting rod slides in the second sliding hole 352, and the width of the portion is less than the distance between the first long side and the second long side of the second sliding hole 352, and is greater than the distance between the two oppositely arranged protrusions. In this way, when the second control member 342 slides in the second sliding hole 352 along the plugging direction, an external force must be applied to enable the second connecting rod to pass through the first limiting portion 313 and the second limiting portion 314. In this way, the first plug connector 331 and the second plug connector 332 are prevented from extending out / entering the through hole 3111 due to misoperation, causing connection failure.

[0057] like Figure 7As shown, an embodiment of the utility model further proposes a portable charging pile 100, which includes a charging gun 1, a first cable 21, a control box 23, a second cable 22 and the plug 3 as described above, wherein the charging gun 1 is connected to the control box 23 via the first cable 21, and the control box 23 is connected to the plug 3 via the second cable 22.

[0058] It can be understood that the charging gun 1 and the plug 3 are connected through the connecting assembly 2. Preferably, the connecting assembly 2 includes a first cable 21, a control box 23 and a second cable 22. When the plug 3 needs to be plugged into a 10A socket, the 10A charging mode is selected on the control box 23, and at the end of the plug 3, the first lever 3411 is moved toward the direction close to the first surface 311 to exceed the first limit portion 313, and the second lever 3421 is moved away from the first surface 311 to exceed the second limit portion 314. Similarly, when the plug 3 needs to be plugged into a 16A socket, the 16A charging mode is selected on the control box 23, and at the end of the plug 3, the first lever 3411 is moved toward the direction away from the first surface 311 to exceed the second limit portion 314, and the second lever 3421 is moved toward the direction close to the first surface 311 to exceed the first limit portion 313. Since the plug 3 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 described one by one here.

[0059] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
