[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Taking A and / or B as an example, it includes technical solution A, technical solution B, and technical solution that satisfies both A and B; in addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0036] 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.

[0037] In view of this, the utility model proposes a charging system, which realizes that a plurality of plug components are arranged on a plug by relatively arranging a first plug surface and a second plug surface on a plug housing, and a first plug component is arranged on the first plug surface, and a second plug component is arranged on the second plug surface, so as to be plugged into different sockets. At the same time, in order to prevent the plug component at the other end from conducting electricity when the first plug component or the second plug component is plugged into the socket, which may bring potential safety hazards, a control device is also provided in the charging system, and when it detects that one of the first plug component and the second plug component is plugged into the socket, the other plug component is controlled to be disconnected from the control box, thereby improving the safety of the entire charging system.

[0038] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-7 As shown, a charging system 100 proposed by the utility model includes a charging gun head 20, a control box 30 and a plug 10, wherein the charging gun head 20 and the control box 30 are connected via a cable 40, and the control box 30 and the plug 10 are connected via a cable 40, and the plug 10 includes a shell 11, wherein the shell 11 has a first plug-in surface 111 and a second plug-in surface 112 which are arranged opposite to each other; a first plug-in component 12 is provided on the first plug-in surface 111, and a second plug-in component 13 is provided on the second plug-in surface 112; a control device is provided in the control box 30, which is configured to, when it is detected that the first plug-in component 12 is plugged into a socket, control the second plug-in component 13 to be disconnected from the control box 30, and when it is detected that the second plug-in component 13 is plugged into a socket, control the first plug-in component 12 to be disconnected from the control box 30.

[0040] In the technical solution adopted in this embodiment, the charging system 100 includes a charging gun head 20, a control box 30 and a plug 10, and a cable 40 is provided between the charging gun head 20 and the control box 30, and a cable 40 is also provided between the control box 30 and the plug 10. When the charging system 100 is used to charge a new energy vehicle, the charging gun head 20 is plugged into the charging socket on the new energy vehicle, and the plug 10 is plugged into the household socket. Preferably, the household socket can be a household 16A / 10A socket. The electric energy in the household 16A / 10A socket is transmitted to the control box 30 through the plug 10 and the cable 40, and then transmitted to the new energy vehicle through the charging gun head 20, so as to realize the charging of the new energy vehicle. The plug 10 is provided with a housing 11. It can be understood that in order to ensure safety and prevent electric shock, the housing 11 is often an insulating housing. A first plug assembly 12 is provided on the first plugging surface 111 of the housing 11, and the first plug assembly 12 is used to plug into a household socket of a certain specification. A second plug-in component 13 is provided on the second plug-in surface 112 of the housing 11, and the second plug-in component 13 is used to plug in a household socket of another specification. Preferably, the first plug-in component 12 can be plugged in a 16A household socket, and the second plug-in component 13 can be plugged in a 10A household socket. It is understandable that the first plug-in component 12 and the second plug-in component 13 can also be plugged in household sockets of other specifications, which is not limited here. A control device is provided in the control box 30, and the control device can detect whether the first plug-in component 12 and the second plug-in component 13 are plugged in with the socket, and when one of the plug-in components is plugged in with the socket, the other plug-in component is controlled to be disconnected from the control box 30. This arrangement prevents current from passing through the other plug-in component when one of the plug-in components is plugged in with the socket, causing a short circuit, thereby causing a safety hazard.

[0041] It is understandable that there are many ways for the control device to detect whether the first plug-in component 12 and the second plug-in component 13 are plugged into the socket, for example, the current and / or voltage on the relevant pins of the first plug-in component 12 and the second plug-in component 13 can be detected. Alternatively, a pressure sensor can be set on the first plug-in surface 111 and the second plug-in surface 112 of the socket. When the first plug-in component 12 or the second plug-in component 13 is plugged into the household socket, the household socket will contact the first plug-in surface 111 or the second plug-in surface 112 to generate pressure. It is understandable that the control device can also detect whether the first plug-in component 12 and the second plug-in component 13 are plugged into the socket in other ways, which are not limited here.

[0042] It is understandable that there are many ways for the control device to control the plug-in component to disconnect from the control box 30. For example, a switch circuit can be set inside the control box 30. When it is necessary to disconnect the relevant path of the plug-in component, it is only necessary to control the switch circuit connected to the path to control the plug-in component to disconnect from the control box 30.

[0043] Furthermore, in an embodiment of the utility model, the first plug-in component 12 includes a first live wire connector and a first neutral wire connector, and the second plug-in component 13 includes a second live wire connector and a second neutral wire connector; the first live wire connector is connected to the control device via a first wire, and the second live wire connector is connected to the control device via a second wire; when the control device detects that the voltage on the first wire exceeds a threshold value, the second wire is controlled to be disconnected, and when the control device detects that the voltage on the second wire exceeds a threshold value, the first wire is controlled to be disconnected.

[0044] It can be understood that the first live wire connector and the first neutral wire connector are used to connect to the live wire plug hole and the neutral wire plug hole in a household socket of one specification, and the second live wire connector and the second neutral wire connector are used to connect to the live wire plug hole and the neutral wire plug hole in another specification of the household socket. The cable 40 between the control box 30 and the charging gun head 20 also includes a first wire and a second wire, wherein the first live wire connector is connected to the control device through the first wire, and the second live wire connector is connected to the control device through the second wire. When the control device detects that the voltage on the first wire exceeds the threshold, the second wire is controlled to be disconnected, so that only the first wire and the charging gun head 20 are turned on, so that only the first plug assembly 12 is in normal operation, and the second plug assembly 13 will not short-circuit or leak. When the control device detects that the voltage on the second wire exceeds the threshold, the first wire is controlled to be disconnected, so that only the second wire and the charging gun head 20 are turned on, so that only the second plug assembly 13 is in normal operation, and the first plug assembly 12 will not short-circuit or leak. It is understandable that the control device can control the disconnection of the first wire or the second wire in a variety of ways. For example, a switch circuit can be set in the control box 30, and the switch circuit can be used to control the charging gun to be connected to only one of the first plug-in component 12 or the second plug-in component 13.

[0045] Furthermore, in an embodiment of the present invention, after the first neutral line connector and the second neutral line connector are connected in the housing 11, they are connected to the control device through a third wire.

[0046] It can be understood that one end of the first neutral line connector and the second neutral line connector are plugged into the household socket, and the other end is in the cavity extending into the housing 11. The first neutral line connector and the second neutral line connector can be connected through a wire in the housing 11, and then connected to the control device through a third wire. When the first plug assembly 12 is plugged into the household socket, the first live wire connector forms a loop through the first wire and the third wire of the first neutral line connector to supply power to the charging gun head 20. At this time, since the second wire has been disconnected, there will be no current and voltage on the second plug assembly 13, and therefore there will be no short circuit.

[0047] Furthermore, in one embodiment of the utility model, the first neutral wire connector is connected to the control device via a third wire, and the second neutral wire connector is connected to the control device via a fourth wire; when the control device detects that the voltage on the first wire exceeds a threshold value, the fourth wire is controlled to be disconnected, and when the control device detects that the voltage on the second wire exceeds a threshold value, the third wire is controlled to be disconnected.

[0048] It can be understood that by connecting the first neutral line connector and the second neutral line connector to the control device through the third wire and the fourth wire respectively, and further controlling the on and off of the third wire and the fourth wire through the control device, the charging safety performance of the entire charging system 100 is ensured.

[0049] Furthermore, in one embodiment of the utility model, the first plug-in assembly 12 also includes a first ground wire connector, and the second plug-in surface 112 also has a second ground wire connector; after the first ground wire connector and the second ground wire connector are connected in the housing 11, they are connected to the control device through a fifth wire.

[0050] It can be understood that one end of the first grounding connector and the second grounding connector are plugged into the household socket, and the other end extends into the cavity inside the housing 11. The first grounding connector and the second grounding connector can be connected through a wire in the housing 11, and then connected to the control device through a fifth wire.

[0051] Furthermore, in an embodiment of the utility model, the plug 10 also includes a protective cover 14, and the protective cover 14 is rotatably connected to the housing 11 through a swing arm 15, so that the protective cover 14 covers the first plug-in surface 111 or the second plug-in surface 112.

[0052] It can be understood that the protective cover 14 is provided with a receiving cavity 142. When the protective cover 14 is covered on the first plug component 12, the first plug component 12 is received in the receiving cavity 142. When the protective cover 14 is covered on the second plug component 13, the second plug component 13 is received in the receiving cavity 142. The protective cover 14 is rotatably connected to the housing 11 through the swing arm 15 to prevent the protective cover 14 from being lost. By providing the protective cover 14, when the first plug component 12 is plugged into the household socket, the protective cover 14 is covered on the second plug component 13. When the second plug component 13 is plugged into the household socket, the protective cover 14 is covered on the first plug component 12, thereby ensuring the beauty of the plug 10.

[0053] Furthermore, in an embodiment of the utility model, the shell 11 also has a first side surface 113 and a second side surface 114 arranged opposite to each other, and a mounting hole 115 is respectively provided on the first side surface 113 and the second side surface 114, and a swing arm 15 is respectively provided corresponding to the mounting hole 115, one end of the swing arm 15 is rotatably connected to the mounting hole 115, and the other end of the swing arm 15 is rotatably connected to the protective cover 14.

[0054] It can be understood that a mounting hole 115 is respectively provided on the first side 113 and the second side 114 of the shell 11, and each mounting hole 115 is correspondingly provided with a swing arm 15, one end of the swing arm 15 is rotatably connected to the mounting hole 115, and the other end of the swing arm 15 is rotatably connected to the protective cover 14, so as to ensure that the protective cover 14 can stably rotate around the shell 11, and further ensure that the protective cover 14 can cover the first plug-in component 12 or the second plug-in component 13.

[0055] Furthermore, in an embodiment of the present invention, the protective cover 14 is provided with connecting ears 141 corresponding to the first side surface 113 and the second side surface 114 , and one end of the connecting ear 141 close to the housing 11 is provided with a connecting hole 143 .

[0056] It can be understood that by providing the connecting ear 141, the protective cover 14 can be moved more smoothly from the first plug component 12 end to the second plug component 13 end, preventing interference between the protective cover 14 and the housing 11 during the rotation of the protective cover 14 around the plug 10.

[0057] Further, in an embodiment of the utility model, the swing arm 15 includes a connecting portion 151 and two connecting posts 152 respectively arranged at both ends of the connecting portion 151, one connecting post 152 passes through the mounting hole 115 to be rotatably connected to the housing 11, and the other connecting post 152 passes through the connecting hole 143 to be rotatably connected to the connecting hole 143. Preferably, a protrusion 153 is further provided at one end of the connecting post 152 away from the connecting portion 151, and a clearance groove 154 is provided on the protrusion 153; the diameter of the protrusion 153 is larger than the diameter of the mounting hole 115 and the connecting hole 143. Preferably, the clearance groove 154 is in a cross shape or a cross shape. It can be understood that when installing the swing arm 15, the protrusion 153 at one end of the swing arm 15 is squeezed into the mounting hole 115. At this time, due to the squeezing of the wall of the mounting hole 115, the spacing between the walls of the give way groove 154 is reduced, and the protrusion 153 shrinks toward the center of the protrusion 153, thereby reducing the overall diameter of the protrusion 153. After the protrusion 153 passes through the mounting hole 115, the mounting hole 115 no longer squeezes the protrusion 153, and the protrusion 153 restores its original diameter, thereby limiting the housing 11 between the protrusion 153 and the connecting portion 151. The installation of the connecting column 152 and the connecting hole 143 is similar to this, and will not be repeated here. Preferably, the connecting column 152 can be made of a deformable material, such as plastic or rubber. Preferably, the connecting portion 151 is arranged between the housing 11 and the corresponding connecting ear 141, and the connecting column 152 is arranged on both sides of the connecting portion 151.

[0058] 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.
