Description

On the premise of ensuring safety and reliability, the on-board discharge system can realize 220V AC power supply on the vehicle, realize more extended functions, and meet more user needs.

[0003] In the related art, a switch is usually used to control a relay or a switch is used to send a power-on request instruction to a corresponding controller.

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The vehicle-mounted power extraction device and the vehicle having the same according to the embodiment of the utility model will be described below with reference to the accompanying drawings. First, the vehicle-mounted power extraction device proposed according to the embodiment of the utility model will be described with reference to the accompanying drawings.

[0036] In view of the problems in the background technology that a large number of relays are used to realize the power-on and power-off effects of the sockets, high temperatures are generated when the relays are connected or disconnected, the reliability of the power-drawing device is poor, and there are safety hazards, the embodiment of the utility model proposes a vehicle-mounted power-drawing device, which does not require the use of relays and their components. By using branch line components and control components to control the inverter device to discharge or stop discharging, the problem that relays in the related technology occupy a large space, are difficult to arrange, and have safety hazards is solved. Not only is the logic simple and the cost low, but it also ensures the stability and reliability of the vehicle-mounted power-drawing device, and is simple and easy to implement.

[0037] Specifically, Figure 1 The present invention is a schematic structural diagram of a vehicle-mounted power supply device provided according to an embodiment of the present utility model.

[0038] like Figure 1 As shown, the vehicle-mounted power supply device 10 includes: an inverter device 100 , a first power supply interface 200 , a second power supply interface 300 , a branching component 400 and a control component 500 .

[0039] Among them, the number of branching components 400 is at least one, the input end of each branching component 400 is connected to the inverter device 100, the first output end of each branching component 400 is connected to the first power supply interface 200, and the second output end of each branching component 400 is connected to the second power supply interface 300; the control component 500, the control component 500 is respectively connected to the first power supply interface 200, the second power supply interface 300 and the inverter device 100, the control component 500 is used to control the inverter device 100 to power the first power supply device through the first power supply interface 200 according to the first power supply signal, or control the inverter device 100 to power the first power supply device through the first power supply interface 200 according to the second power supply signal, and at the same time, power the second power supply device through the second power supply interface 300.

[0040] In some embodiments, the first power interface 200 is a power socket, and the second power interface 300 is an AC charging port.

[0041] Specifically, in some embodiments of the utility model, the first power supply interface 200 is a power supply socket, which can output high-voltage current to supply power to power supply equipment, such as refrigerators, other vehicles to be charged, etc.; the second power supply interface 300 can be a 220V AC charging port, which can charge the vehicle by connecting a charging gun, and can also output 220V AC power to charge other vehicles. When the control component 500 obtains the first power supply signal, it sends a control signal to control the inverter device 100 to supply power to the first power supply interface 200; when the control component 500 obtains the second power supply signal, it sends a control signal to control the inverter device 100 to supply power to the second power supply interface 300.

[0042] Optionally, in some embodiments, all the breakout components 400 are breakouts.

[0043] Specifically, if Figure 2 As shown, there is at least one branching assembly 400 in the embodiment of the utility model, and the input ends of all branching assemblies 400 are respectively connected to the inverter device 100, all first output ends are connected to the first power supply interface 200, and all second output ports are connected to the second power supply interface 300. When the inverter receives the control instruction and discharges, the current is shunted by the branching device and output to the first power supply interface 200 and the second power supply interface 300 respectively, so that the first power supply interface 200 and the second power supply interface 300 can work at the same time, so that the vehicle can be charged and run at the same time.

[0044] Optionally, in some embodiments, the vehicle-mounted power supply device 10 further includes: a first power supply switch 201. The first power supply switch 201 is configured corresponding to the first power supply interface 200, one end of the first power supply switch 201 is connected to the control component 500, and the other end of the first power supply switch 201 is connected to the ground node, and the first power supply switch 201 generates a first power supply signal when it is triggered.

[0045] Specifically, one end of the first power switch 201 is connected to the control component 500, and the other end is grounded. When the first power switch 201 is closed, it indicates that the first power interface 200 of the vehicle has a power demand. At this time, a first power signal is sent to the control component 500, indicating that the first power interface 200 needs to draw power. After analyzing that the discharge conditions are met, the control component 500 controls the inverter device 100 to supply power to the first power interface 200.

[0046] Optionally, in some embodiments, the vehicle-mounted power supply device 10 further includes: a second power supply switch 301, a detection component (not shown in the figure) and a first signal generating component (not shown in the figure). Among them, one end of the second power supply switch 301 is connected to the ground node, and the other end of the second power supply switch 301 is connected to the control component 500; the detection component is connected to the control component 500, and the detection component is used to detect whether the second power supply interface 300 is connected to the second power supply device; the first signal generating component is respectively connected to the second power supply switch 301, the detection component and the control component 500, and the first signal generating component generates a power-off signal when the second power supply switch 301 is in the open state and the second power supply interface 300 is not connected to the second power supply device, so that the control component 500 stops supplying power to the first power supply device based on the power-off signal.

[0047] It is understandable that when the second power switch 301 is closed, the control component 500 controls the inverter device 100 to supply power to the second power interface 300 after receiving the power signal, and the high-voltage current flows through the second power interface 300. If the second power interface 300 is not connected to the second power device at this time, the second power interface 300 is exposed to the outside, and it is easy to cause a leakage accident, which is extremely dangerous. Therefore, when the utility model detects that the second power interface 300 is not connected to the second power device, it will generate a power-off signal to stop supplying power.

[0048] Specifically, the detection component detects whether the second power supply interface 300 is connected to the second power supply device. If it is found that the second power supply interface 300 is not connected to the second power supply device, a device disconnection signal is sent to the first signal generating component. When the first signal generating component detects that the second power supply switch 301 is in the open state, a power-off signal is generated and sent to the control component 500. The control component 500 controls the inverter device 100 to stop discharging, and the first power supply interface 200 and the second power supply interface 300 stop drawing power at the same time.

[0049] Optionally, in some embodiments, the vehicle-mounted power supply device 10 further includes: a second signal generating component.

[0050] The second signal generating component is connected to the second power taking switch 301, the detection component and the control component 500 respectively, and the second signal generating component is connected to the second power taking device at the second power taking interface 300, and generates a second power taking signal when the second power taking switch 301 is in the open state.

[0051] Specifically, when the first power supply interface 200 is connected to the power supply device, if the second power supply switch 301 is in the open state, the second signal generating component generates a second power supply signal and sends it to the control component 500. After receiving the second power supply signal, the control component 500 controls the inverter device 100 to output the voltage. When the voltage flows through the branching component 400, it is diverted to supply power to the first power supply interface 200 and the second power supply interface 300 respectively.

[0052] Optionally, in some embodiments, the vehicle-mounted power supply device 10 further includes: a first reminder component, wherein the first reminder component is connected to the control component 500, and the first reminder component performs a power-off reminder when the control component 500 stops supplying power to the first power supply device based on the power-off signal.

[0053] Specifically, after obtaining the power-off signal sent by the control component 500, the first reminder component will make an acoustic reminder, or an optical reminder, or both an acoustic reminder and an optical reminder, to remind the user that there is no device connected to the second power supply interface 300, to prevent the risk of leakage and to stop supplying power to the first power supply device, such as lighting a red light or sounding a buzzer alarm.

[0054] Optionally, in some embodiments, the vehicle-mounted power supply device 10 further includes: a second reminder component. The second reminder component is arranged corresponding to the second power supply interface 300, the second reminder component is connected to the control component 500, and the second reminder component is used to provide acoustic and / or optical reminders when the inverter device 100 supplies power to the first power supply device through the first power supply interface 200.

[0055] Wherein, in some embodiments, the second reminder component includes:

[0056] An acoustic reminder unit, which is connected to the control assembly 500 and is used to provide an acoustic reminder when the inverter device 100 supplies power to the first power-taking device through the first power-taking interface 200;

[0057] And / or, an optical reminder unit, the optical reminder unit is connected to the control component 500 , and the optical reminder unit is used to perform an optical reminder when the inverter device 100 supplies power to the first power taking device through the first power taking interface 200 .

[0058] Specifically, when the vehicle-mounted power supply device 10 is working normally and the inverter device 100 supplies power to the first power supply interface 200 and the first power supply device, the second reminder component will make an acoustic reminder, or an optical reminder, or both an acoustic reminder and an optical reminder, to remind the user that a high voltage current is passing through the second power supply interface 300 at this time and the user should pay attention to the danger of electric shock due to leakage, such as lighting a red light or sounding a buzzer alarm next to the second power supply interface 300.

[0059] In summary, the vehicle-mounted power supply device of the utility model uses a branching component to replace the relay in the related technology to shunt the current, so that the inverter device can supply power to the charging port and the power socket at the same time, and at the same time remind the user when the power is off, so that the user can detect it in time and eliminate safety hazards.

[0060] The vehicle-mounted power supply device proposed in the embodiment of the utility model eliminates the relay and its components and uses the branch line component and the control component to control the inverter device to discharge or stop discharging, thereby solving the problem in the related art that the relay occupies a large space, is difficult to arrange and has potential safety hazards. It not only has simple logic and low cost, but also ensures the stability and reliability of the vehicle-mounted power supply device, and is simple and easy to implement.
