[0035] The present application is described more clearly below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the effects of the present application, but are not intended to limit the present application in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present application. These all fall within the scope of protection of the present application.

[0036] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0037] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0038] In the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0039] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0040] In addition, the “plurality” mentioned in the embodiments of the present application should be interpreted as two or more.

[0041] 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.

[0042] In the prior art, a relay is usually arranged in the neutral and live wire paths of the power socket, and a key switch is used to control the on and off of the relay, thereby controlling the power supply of the power socket. Since the relay is connected in series in the neutral and live wire paths of the power socket, arcs are easily generated during the switching process, affecting the safety of the power socket.

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

[0044] Figure 1 This is a schematic diagram of the structure of a car power socket provided by an embodiment of the utility model. Figure 1 , the in-vehicle power socket comprises: a socket body 10 and a touch device 20;

[0045] 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 external AC power supply device 30;

[0046] The touch device 20 is connected to the enable terminal of the AC power supply device 30; the touch device 20 is used to respond to the user's touch operation and send a power supply control signal to the AC power supply device 30;

[0047] The AC power supply device 30 is used to output AC power to the socket body 10 in response to the power supply control signal.

[0048] Figure 1 The schematic diagram of the application scenario of the in-vehicle power socket in the embodiment of the utility model is shown. The touch device 20 obtains the user's touch operation and sends a power supply control signal to the AC power supply device 30. The AC power supply device 30 supplies power to the socket body 10 according to the power supply control signal. The embodiment of the utility model controls the power supply of the socket body 10 through the touch device 20. There is no need to set a relay inside the socket body 10, and no arc will be generated, thereby improving the safety and reliability of the in-vehicle power socket.

[0049] Meanwhile, in the prior art, the on-off of the relay is controlled by a key switch, thereby controlling the power supply of the socket. Since the key directly controls the on-off of the relay, it is usually arranged together with the socket body 10. In the embodiment of the utility model, the touch switch K1 does not directly control the socket body 10, but indirectly controls the power supply of the socket body 10 by controlling the output of the AC power supply device 30. The touch device 20 can be arranged at any position in the car. The arrangement position of the touch device 20 is more flexible and can be arranged at any position in the car, which is convenient for users to operate.

[0050] For example, the power socket in the car is in the back row, and the touch device 20 can be set in the front row. The user can directly control the power supply of the power socket in the back row in the front row, which improves the user experience.

[0051] Furthermore, the AC power supply device 30 includes: a power supply control module 31, the power supply control module 31 obtains a power supply control signal, and enables the output of AC power according to the power supply control signal. For example, when the power supply control signal is detected to be at a high level, the AC power supply device 30 outputs AC power; when the power supply control signal is detected to be at a low level, the AC power supply device 30 does not output AC power.

[0052] It should be noted that the control logic of the power supply control module 31 includes but is not limited to the above, which is specifically a conventional technical means in the field and is not within the protection scope of this application.

[0053] In a further embodiment, reference Figure 2 The number of the touch devices 20 may be two or more; each touch device 20 is connected to the AC power supply device 30 .

[0054] In the embodiment of the utility model, multiple touch devices 20 can be arranged in the vehicle, each touch device 20 is connected to the AC power supply device 30, and each touch device 20 can independently control the output of the AC power of the AC power supply device 30. Each touch device 20 is distributed at different positions in the vehicle, and users at different positions in the vehicle can control the power supply of the socket body 10, which is convenient for user operation.

[0055] Exemplarily, each touch device 20 is configured to have only one touch button; when the user touches the button, a high level pulse is sent to the AC power supply device 30. The AC power supply device 30 is configured to stop outputting AC power to the socket body 10 when receiving the high level pulse if the AC power supply device 30 currently outputs AC power normally; and to output AC power to the socket body 10 when receiving the high level pulse if the AC power supply device 30 currently does not output AC power.

[0056] In the embodiment of the utility model, the user can control the power supply of the socket body 10 through any touch device 20, which is convenient for the user.

[0057] Figure 3 A schematic diagram showing the connection relationship between some components of a new energy vehicle.

[0058] refer to Figure 3 There is a communication connection and an electrical connection between the on-board charger and the power battery, and the on-board charger controls the charging and discharging of the power battery; the central control screen is connected to the on-board charger for displaying various power parameters such as the remaining charging time, current power, charging current and voltage, and charging efficiency; the body controller is connected to the central control screen for receiving various control parameters input by the central control screen, or sending various display control parameters to the central control screen.

[0059] Since the on-board charger can invert the DC power of the power battery into AC power, based on this, in a possible implementation, the AC power supply device 30 can be the on-board charger, and the power supply control module 31 is the controller of the on-board charger. The on-board charger is directly used to power the socket body 10, and there is no need to set up an additional AC power supply device 30.

[0060] In another possible implementation, the touch device 20 may be a touch display screen; the touch display screen is a large screen of the vehicle computer.

[0061] refer to Figure 3 Since the vehicle screen can obtain the user's touch operation and the vehicle screen can communicate directly with the vehicle charger, the vehicle screen can be used as the touch device 20 in the embodiment of the utility model, and no additional touch device 20 is required.

[0062] Corresponding to the above embodiment, refer to Figure 4 The vehicle computer large screen communicates with the vehicle-mounted charger through the CAN network. The vehicle computer large screen sends a power supply control signal to the vehicle-mounted charger according to the user operation. The vehicle-mounted charger controls the discharge of the power battery according to the power supply control signal, thereby supplying power to the socket body 10.

[0063] For example, the large screen of the vehicle is provided with an on icon and an off icon. When the user clicks the on icon, the power supply control signal is the first signal, and after receiving the first signal, the onboard charger controls the power battery to discharge and supply power to the socket body 10;

[0064] When the user clicks the close icon, the power supply control signal is the second signal. After receiving the second signal, the on-board charger controls the power battery not to discharge, and the socket body 10 is not charged.

[0065] For another example, a socket control icon is provided on the large screen of the vehicle computer. By default, the power socket in the vehicle is not charged. When the user clicks the socket control icon for the first time, the on-board charger receives a first signal and supplies power to the socket body 10. When the user clicks the socket control icon again, the on-board charger receives a second signal and does not output power to the socket body 10.

[0066] For another example, every time the vehicle is turned off and restarted, the body controller sends an initialization command to the large screen of the vehicle computer. After receiving the initialization command, the large screen of the vehicle computer sends a second signal to the on-board charger to control the on-board charger not to output power to the socket body 10, thereby ensuring that the power socket in the vehicle is not energized and improving the safety of the use of the power socket.

[0067] In one possible implementation, reference Figure 5 , the enabling end of the AC power supply device 30 may include: a first signal end com1 and a second signal end com2; the touch device 20 may include: a touch switch K1; the touch switch K1 is arranged on the power socket body 10;

[0068] A first end of the touch switch K1 is connected to the first signal end com1 , and a second end of the touch switch K1 is connected to the second signal end com2 .

[0069] The touch switch K1 can be arranged on the socket body 10, so that the user can directly switch on or off the power supply of the in-vehicle power socket through the touch device 20 when inserting the plug. At the same time, the AC power supply device 30 obtains the user's touch operation by detecting the conduction state of the touch switch K1, thereby controlling the output of AC power.

[0070] In one possible implementation, reference Figure 5 , the AC power supply device 30 may include: a DC power supply VCC1, a first resistor R1 and a power supply control module 31;

[0071] The first end of the first resistor R1 is connected to the first signal terminal com1 and the first input terminal of the power supply control module 31 respectively, and the second end of the first resistor R1 is connected to the DC power supply VCC1;

[0072] The second signal terminal com2 and the second input terminal of the power supply control module 31 are both grounded.

[0073] The AC power supply device 30 can have a built-in DC power supply VCC1 as an excitation source, which forms a DC power supply VCC1 with the first resistor R1 and the touch switch K1. Figure 5 The circuit structure shown in the figure determines the conduction state of the touch switch K1 by detecting the voltage difference between the first signal terminal com1 and the second signal terminal com2. For example, when the AC power supply device 30 detects that the voltage difference between the first signal terminal com1 and the second signal terminal com2 is less than the first preset voltage, it determines that the touch switch K1 is closed; when the AC power supply device 30 detects that the voltage difference between the first signal terminal com1 and the second signal terminal com2 is greater than the second preset voltage, it determines that the touch switch K1 is disconnected.

[0074] Specifically, it can be defined that when the touch switch K1 is closed, the socket body 10 is powered, and when the touch switch K1 is disconnected, the socket body 10 is not powered. Therefore, when the AC power supply device 30 detects that the touch switch K1 is closed, no power is output; when the AC power supply device 30 detects that the touch switch K1 is disconnected, AC power is output normally.

[0075] In a possible implementation, the touch device 20 is connected to the AC power supply device 30 via a CAN bus.

[0076] In a possible implementation, the in-vehicle power socket may further include: a display device;

[0077] The display device is connected to the socket body 10 and is used to display the charged state of the socket body 10 .

[0078] More specifically, the display device may also be used to display power consumption data such as the power consumption of the power socket in the vehicle.

[0079] In one possible implementation, reference Figure 6, the display device may include: a rectifying unit BD1, a first capacitor C1, a second capacitor C2, a second resistor R2, a third resistor R3, a switch tube Q1 and a light emitting diode D1;

[0080] The first input terminal and the second input terminal of the rectifier unit BD1 are respectively connected to the neutral wire jack and the live wire jack of the socket body 10, the positive output terminal of the rectifier unit BD1 is respectively connected to the first end of the first capacitor C1, the first end of the second resistor R2 and the first end of the third resistor R3, and the negative output terminal of the rectifier unit BD1 is grounded;

[0081] The first end of the switch tube Q1 is connected to the cathode of the light emitting diode D1, the control end of the switch tube Q1 is connected to the second end of the second resistor R2, the control end of the switch tube Q1 is also grounded through the second capacitor C2, and the second end of the switch tube Q1 is grounded;

[0082] The anode of the light emitting diode D1 is respectively connected to the first end of the second resistor R2, the first end of the first capacitor C1 and the positive output end of the rectifying unit BD1 through the third resistor R3;

[0083] A second terminal of the first capacitor C1 is grounded.

[0084] Exemplarily, the switch tube Q1 can be an NPN transistor. When the socket body 10 is charged, the first capacitor C1 is charged, the base of the transistor is turned on at a high level, and the light-emitting diode D1 emits light, indicating that the socket body 10 is charged;

[0085] When the socket body 10 is not charged, the first capacitor C1 is discharged, the voltage is reduced, the base of the transistor is at a low level, the transistor is disconnected, and the light-emitting diode D1 does not emit light, indicating that the socket body 10 is not charged.

[0086] Through the above simple device list, the LED D1 can be used to indicate whether the socket body 10 is charged, and the user can intuitively see whether the socket body 10 is charged. The above circuit structure is simple, the number of devices is small, the volume is small, and the cost is low.

[0087] In a possible implementation manner, the rectifier unit BD1 may be a rectifier bridge.

[0088] The rectifying unit BD1 may be a rectifying bridge, which can be used to rectify the alternating current to charge the first capacitor C1 , and has low cost and small size.

[0089] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
