[0041] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0042] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0043] The following is a detailed description of the implementation of the present invention in conjunction with the specific drawings:

[0044] On-board charger (OBC) is also called on-board charger. As the name implies, it is a charger fixed on the electric vehicle. OBC can convert the alternating current (AC) from the power grid into the direct current (DC) required by the high-voltage battery of the electric vehicle to charge the power battery of the electric vehicle; it can also invert the DC power of the power battery into AC power and feed it back to the power grid. Therefore, for new energy vehicles, an AC charging socket can be set up in the car, which is directly powered by the OBC to meet the user's AC power supply needs.

[0045] In the prior art, the socket in the car is always charged, and when the plug is inserted into the socket, the power on the socket can flow into the load at the end of the power plug to supply power to the load. Therefore, when there are children in the car, it is easy to insert the conductor into the socket, causing electric shock accidents, which seriously affects the safety of the socket.

[0046] Based on the above, the present invention provides a schematic diagram of the structure of a power socket. Figure 1 , the power socket comprises: a socket body 10 and a detection switch K1;

[0047] The neutral wire jack (N) and the live wire jack (L) of the socket body 10 are respectively connected to the neutral wire terminal and the live wire terminal of the AC power supply device 20;

[0048] The detection switch K1 is connected to the enable terminal (Sig) of the AC power supply device 20;

[0049] When the plug is inserted into the jack of the socket body 10, the conduction state of the detection switch K1 changes, and a power supply signal is sent to the enable terminal (Sig) of the AC power supply device 20;

[0050] When receiving the power supply signal, the AC power supply device 20 outputs AC power to the socket body 10 .

[0051] In the embodiment of the utility model, when the plug is inserted into the socket of the socket body 10, the conduction state of the detection switch K1 changes, thereby generating a power supply signal and sending it to the AC power supply device 20. The AC power supply device 20 will then output AC power to the socket body 10, ensuring that the socket body 10 is energized when the plug is inserted into the socket of the socket body 10.

[0052] For example, when the plug is inserted into the socket body 10, the detection switch K1 is closed and turned on, and the enable end (Sig) of the AC power supply device 20 is at a low level; when the plug is detached from the socket body 10, the detection switch K1 is disconnected, and the enable end (Sig) of the AC power supply device 20 is at a high level; that is, the power supply signal can be a low level or a high level to low level jump. When the enable end of the AC power supply device 20 detects a low level or a high level to low level jump, the AC power supply device 20 outputs electrical energy to the socket body 10; otherwise, the socket body 10 is not powered.

[0053] When the plug is not inserted into the socket body 10, the socket body 10 is not electrified, and even if the user touches it by mistake, it will not cause a safety accident; and when the socket body 10 is electrified, since the plug has been inserted into the socket body 10, the three jacks of the socket body 10 (the ground wire socket, the neutral wire socket and the live wire socket) are covered by the plug, and the user will not touch them by mistake, which can effectively avoid safety accidents caused by accidental touching of the socket, ensure the safety of users' electricity use, and improve the safety of vehicle use.

[0054] It should be noted that the above-mentioned power socket includes but is not limited to the power socket in the car, and can also be a household power socket, which can be suitable for different application scenarios and ensure the safety of the socket use.

[0055] In a possible implementation, when the plug is inserted into the jack of the socket body 10, the detection switch K1 is turned on;

[0056] When the plug is separated from the insertion hole of the socket body 10, the detection switch K1 is turned off.

[0057] In the embodiment of the utility model, when the plug is inserted into the jack of the socket body 10, the detection switch K1 is turned on, and when the enabling end of the AC power supply device 20 detects that the detection switch K1 is turned on, the socket body 10 is powered. Otherwise, no power is output.

[0058] Exemplarily, the socket body 10 has a built-in first DC power source VCC1 as an excitation source, which forms a first resistor R1 and a detection switch K1. Figure 2 When the plug is inserted into the socket body 10, the detection switch K1 is turned on, and the enable terminal (Sig) of the AC power supply device 20 is at a low level. Figure 3 When the plug is out of the socket body 10, the detection switch K1 is disconnected, the enabling end of the AC power supply device 20 is high, reference Figure 3 The power supply signal is at a low level. When the AC power supply device 20 detects a low level, the AC power supply device 20 supplies power to the socket body 10, and the socket body 10 is energized.

[0059] For another example, the first DC power source VCC1, the first resistor R1 and the detection switch K1 form Figure 4 When the plug is inserted into the socket body 10, the detection switch K1 is turned on, the enable end of the AC power supply device 20 is high, reference Figure 5 When the plug is out of the socket body 10, the detection switch K1 is disconnected, the enabling end of the AC power supply device 20 is low, reference Figure 5 The power supply signal is at a high level. When the AC power supply device 20 detects a high level, the AC power supply device 20 supplies power to the socket body 10, and the socket body 10 is energized.

[0060] In another possible implementation, when the plug is inserted into the insertion hole of the socket body 10 , the detection switch K1 is opened; when the plug is separated from the insertion hole of the socket body 10 , the detection switch K1 is closed.

[0061] In the embodiment of the utility model, when the plug is inserted into the socket body 10, the detection switch K1 can be disconnected; otherwise, the detection switch K1 is closed. Similarly, the change of the switch state of the detection switch K1 causes the change of the level of the enable end (Sig) of the AC power supply device 20, and the AC power supply device 20 controls the power supply by detecting the change of the level. The specific principle is the same as above and will not be repeated here.

[0062] In one possible implementation, reference Figure 6 , the detection switch K1 can be a micro switch; the detection switch K1 is arranged between the ground wire socket, the neutral wire socket and the live wire socket of the socket body 10;

[0063] When the plug is inserted into the socket of the socket body 10, the micro switch is pressed to conduct when it is subjected to the pressure of the plug;

[0064] When the plug is separated from the insertion hole of the socket body 10, the micro switch is not subjected to the pressure of the plug and is disconnected.

[0065] Based on the above embodiments, refer to Figure 6The detection switch K1 can be a micro switch, which is arranged between the ground wire socket, the neutral wire socket and the live wire socket of the socket body 10. The button of the micro switch (K1) is provided with an elastic component. When the plug is inserted into the socket body 10, the button of the micro switch (K1) is squeezed, and the micro switch (K1) is turned on under pressure; when the plug is separated from the socket body 10, the micro switch (K1) is not subjected to pressure, and the elastic component pushes the button to automatically pop open, and the micro switch (K1) is disconnected. Therefore, when the plug is inserted into the socket body 10, the socket body 10 is energized; and when the plug is separated from the socket body 10, the socket body 10 is automatically powered off; therefore, the socket body 10 is only energized when electricity is used, which effectively ensures the safety of the use of the power socket.

[0066] In one possible implementation, reference Figure 7 , the enabling terminal of the AC power supply device 20 may include: a first signal terminal com1 and a second signal terminal com2;

[0067] The first signal terminal com1 is connected to a first terminal of the detection switch K1 , and the second signal terminal com2 is connected to a second terminal of the detection switch K1 .

[0068] The AC power supply device 20 may include a first signal terminal com1 and a second signal terminal com2, which are respectively connected to two ends of the detection switch K1, and the conduction state of the detection switch K1 is directly detected through the first signal terminal com1 and the second signal terminal com2, so as to control the power supply.

[0069] Specifically, the AC power supply device 20 may have a built-in second DC power source VCC2 as an excitation source, which forms a second DC power source with the second resistor R2 and the detection switch K1. Figure 7 The circuit structure shown determines the conduction state of the detection switch K1 by detecting the voltage difference between the first signal terminal com1 and the second signal terminal com2.

[0070] The detection logic for detecting the on-state of the switch K1 is a conventional technical means and is executed in the AC power supply device 20. This application only protects the power socket, and the specific detection logic is not within the protection scope of this application.

[0071] The circuit structure for detecting the conduction state of the detection switch K1 by the built-in excitation source in the AC power supply device 20 includes but is not limited to Figure 7 The circuit structure may also be other circuit structures, which are not specifically limited here.

[0072] In a possible implementation, when the plug is inserted into the jack of the socket body 10, the detection switch K1 is turned on; when the plug is removed from the jack of the socket body 10, the detection switch K1 is turned off; Figure 8 and Fig. 9The power socket may also include: a high voltage connector (J1A and J1B); the high voltage connector includes: a high voltage male connector J1A and a matching high voltage female connector J1B;

[0073] The neutral wire jack and the live wire jack of the socket body 10 are respectively connected to the neutral wire terminal and the live wire terminal of the AC power supply device 20 through high-voltage connectors (J1A and J1B);

[0074] The first signal terminal com1 is connected to the first terminal of the detection switch K1, and the second terminal of the detection switch K1 is connected to the first terminal of the high-voltage male connector J1A; the first terminal of the high-voltage male connector J1A corresponds to the first terminal of the high-voltage female connector J1B;

[0075] The second signal terminal com2 is connected to the second terminal of the high-voltage male connector J1A; the second terminal of the high-voltage male connector J1A corresponds to the second terminal of the high-voltage female connector J1B;

[0076] The first wiring terminal of the high-voltage female connector J1B is short-circuited to the second wiring terminal of the high-voltage female connector J1B.

[0077] When the power socket is set in a new energy vehicle, the power socket is usually connected to the AC power supply device 20 (for example, the AC power supply device 20 is an OBC) through a high-voltage connector (J1A and J1B). In the vehicle, the high-voltage connector is usually provided with an interlock detection, refer to Figure 8 When the high-voltage male connector J1A and the matching high-voltage female connector J1B are firmly connected, the first terminal of the high-voltage male connector J1A and the second terminal of the high-voltage male connector J1A are short-circuited and connected.

[0078] In the embodiment of the utility model, the interlocking connection line is reused, and the interlocking connection line is connected in series with the detection switch K1, so as to simultaneously detect whether the high-voltage male connector J1A and the high-voltage female connector J1B are tightly connected. If the detection switch K1 is not closed, or the high-voltage male connector J1A is disconnected from the high-voltage female connector J1B, the AC power supply device 20 does not output power.

[0079] In a possible implementation manner, the first terminal of the high voltage female connector J1B is short-circuited with the second terminal of the high voltage female connector J1B via a U-shaped pin.

[0080] The first signal terminal com1 is connected to the first terminal of the detection switch K1 through a high-voltage connector, and the second signal terminal com2 is also connected to the socket body 10 through a high-voltage connector and then connected to the second terminal of the high-voltage male connector J1A to form Figure 8The first signal terminal com1, the second signal terminal com2 and the AC power are all connected to the AC power supply device 20 through the high-voltage connector, which can simultaneously detect the detection switch K1 and the connection state of the high-voltage connector.

[0081] In another possible implementation, reference Fig. 9 , the power socket may also include: low voltage connectors (J2A and J2B);

[0082] The first end of the detection switch K1 is connected to the first signal terminal com1 through the low voltage connector (J2A and J2B);

[0083] The second connection terminal of the high voltage male connector J1A is connected to the second signal terminal com2 through the low voltage connector.

[0084] Since the voltage of alternating current is relatively high, in order to avoid the influence of high-voltage alternating current on low-voltage signals (power supply signals), a low-voltage connector (including a low-voltage male connector J2A and a matching low-voltage female connector J2B) is separately provided in the embodiment of the utility model, and the first end of the detection switch K1 and the second terminal of the high-voltage male connector J1A are connected to the AC power supply device 20 through the low-voltage connector from the socket body 10, which can effectively avoid the influence of high-voltage alternating current on low-voltage signals and provide reliability of the power socket.

[0085] In a possible implementation, the power socket may further include: a safety element;

[0086] The live wire socket of the socket body 10 is connected to the live wire terminal of the AC power supply device 20 through a safety element.

[0087] In the embodiment of the utility model, a safety element is provided between the live wire jack of the socket body 10 and the live wire terminal of the AC power supply device 20 to improve the safety and reliability of the power socket.

[0088] Specifically, the safety element may be disposed inside the socket body 10 , and the live wire socket of the socket body 10 is led out of the socket body 10 after passing through the safety element and connected to the AC power supply device 20 .

[0089] Exemplarily, the insurance element may be a fuse.

[0090] In a possible implementation, the output voltage of the AC power supply device 20 may be 220V.

[0091] The output voltage of the AC power supply device 20 includes but is not limited to 220V, and can be set according to actual application requirements.

[0092] Corresponding to any of the above-mentioned power sockets, an embodiment of the utility model further provides a vehicle, which includes any of the above-mentioned power sockets and has the advantages of the above-mentioned power sockets, which will not be repeated here.
