Summary of the Invention

Problems to be Solved by the Invention

[0004] In the vehicle power supply system described in Patent Document 1, after rotating a blocking member that serves as a switch function for turning on / off the power supply state to expose the plug insertion port of the outlet, it is necessary to insert the plug of the electrical equipment into the outlet. However, the operation of rotating this blocking member is troublesome for the user.

[0005] The present disclosure has been made in view of the above problems, and an object thereof is to provide a vehicle power supply device that eliminates troublesome operations for turning on the power supply state.

Means for Solving the Problems

[0006] In order to solve the above problems, one aspect of the disclosed technology is a vehicle power supply device that supplies power to an electrical device, comprising: a socket into which a plug of the electrical device is inserted; and a switch that switches the power supply state to on by being pushed down by a conductor blade of the plug inserted into the socket, and switches the power supply state to off if not pushed down by the conductor blade.

Advantages of the Invention

[0007] According to the vehicle power supply device of the present disclosure, since the power supply state is turned on simply by inserting the plug of the electrical device into the plug insertion port of the socket, there is no troublesome operation for the user. Therefore, it is possible to prevent power consumption during standby when the electrical device is not inserted into the socket.

Modes for Carrying Out the Invention

[0009] The vehicle power supply device according to the present disclosure adds a switch mechanism to the socket that turns on the inverter operation when a plug is inserted into the insertion port and turns off the inverter operation if no plug is inserted into the insertion port. With this mechanism, it is possible to eliminate power consumption during standby without requiring troublesome operations for the user. Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings.

[0010] <Embodiment> [Structure] FIG. 1 is a front view for explaining the structure of a vehicle power supply device 100 according to an embodiment of the present disclosure. FIG. 2 is a view showing a cross section taken along line A-A of the vehicle power supply device 100 illustrated in FIG. 1 and a plug 210 of an electrical device.

[0011] The vehicle power supply device 100 shown in FIGS. 1 and 2 is a device provided in a vehicle and can supply predetermined power to electrical devices (not shown) such as home appliances electrically connected to the vehicle.

[0012] As this vehicle power supply device 100, an inverter device that can supply power (for example, AC1500W) by an AC power source can be exemplified.

[0013] The vehicle power supply device 100 includes an outlet (or receptacle) 110, an inverter switch 130, and an inverter circuit 140.

[0014] The outlet 110 is a power supply connection device for supplying power to an electrical device. This outlet 110 has one or more insertion ports (plug receptacles) 120 for inserting a plug 210 of an electrical device. The outlet 110 is electrically connected to a power supply source (not shown) such as an in-vehicle battery so as to be able to supply power to the plug 210 inserted into the insertion port 120.

[0015] The inverter switch 130 is a switch component provided in one of a pair of holes constituting the insertion port 120 of the outlet 110. This inverter switch 130 has a switch knob 131 and a contact portion 132, and is configured such that the contact portion 132 is electrically conducted when the switch knob 131 is pushed in.

[0016] The inverter circuit 140 is a power converter for converting a DC power source (e.g., DC 12V) such as an in-vehicle battery into a predetermined AC power source (e.g., AC 100V). This inverter circuit 140 is configured to operate (ON) / not operate (OFF) the inverter corresponding to the conduction state (ON) / cut-off state (OFF) of the inverter switch 130.

[0017] [Operation] Referring to FIG. 2 and further FIG. 3, the operation of the vehicle power supply device 100 will be described. The cross-sectional view taken along line A-A of the vehicle power supply device 100 shown in FIG. 2 also shows the state of the inverter switch 130 when the plug 210 of the electrical device is not inserted into the insertion port 120 of the power outlet 110. FIG. 3 is a diagram showing the state of the inverter switch 130 when the plug 210 of the electrical device is inserted into the insertion port 120 of the power outlet 110 in the cross-sectional view taken along line A-A of the vehicle power supply device 100 shown in FIG. 2.

[0018] As shown in FIG. 2, when the plug 210 of the electrical device is not inserted into the insertion port 120 of the power outlet 110, the switch knob 131 of the inverter switch 130 is not pushed in. Therefore, the contact portion 132 of the inverter switch 130 is in an electrically non-conductive state (OFF) that is cut off. In the state where this contact portion 132 is cut off, since the inverter circuit 140 is not connected to a power supply source (not shown) such as an in-vehicle battery, the inverter does not operate (OFF). Thus, power consumption by the inverter circuit 140 during standby can be eliminated.

[0019] On the one hand, as shown in FIG. 3, when the plug 210 of an electrical device is inserted into the insertion port 120 of the socket 110, the switch knob 131 of the inverter switch 130 is pushed in by the conductor blade 220 of the plug 210. Therefore, the contact portion 132 of the inverter switch 130 is in an electrically conductive state (ON). In this state where the contact portion 132 is conductive, the inverter circuit 140 is connected to a power supply source (not shown) such as an in-vehicle battery, and the inverter operates (ON). Thus, power is supplied to the electrical device connected to the socket 110.

[0020] FIG. 4 is a diagram for explaining the state of the inverter operation in the inverter circuit 140 with respect to the operation of the plug 210 of the electrical device. As shown in FIG. 4, when the plug 210 of the electrical device is inserted into the insertion port 120 of the socket 110, the inverter transitions from the non-operating state (OFF) to the operating state (ON), and when the plug 210 of the electrical device is removed from the insertion port 120 of the socket 110, the inverter transitions from the operating state (ON) to the non-operating state (OFF).

[0021] <Function and Effect> As described above, the vehicle power supply device 100 according to an embodiment of the present disclosure has a structure in which an inverter switch 130 is provided (built in) in the socket 110 into which the plug 210 of the electrical device is inserted, and the switch knob 131 of the inverter switch 130 is pushed down by the conductor blade 220 of the plug 210 inserted into the socket 110. The inverter switch 130 is provided with a function of automatically switching on the power supply state to the inverter circuit 140 when the switch knob 131 is pushed down by the conductor blade 220 so that the contact portion 132 is conductive.

[0022] With such a structure, in a scenario where a user uses an electrical device, by inserting the plug 210 of the electrical device into the insertion port 120 of the power outlet 110, power is supplied to the inverter circuit 140, and by removing the plug 210 of the electrical device from the insertion port 120 of the power outlet 110, the power supply to the inverter circuit 140 is cut off, thus enabling the construction of such a mechanism.

[0023] Therefore, there is no need to provide a physical switch (such as a button or lever) for the user to switch the operation / non-operation of the inverter, and a sense of security can be obtained that the power outlet in the vehicle (the power outlet 110 of the vehicle power supply device 100) can be used in the same way as a household power outlet provided on a wall surface of a house. Also, since no physical switch is provided, there is no such situation as forgetting to turn on the switch before using the electrical device and thus being unable to use the electrical device immediately, or forgetting to turn off the switch after using the electrical device and wasting standby power.

Industrial Applicability

[0024] The vehicle power supply device of the present disclosure can be used when supplying power to an electrical device electrically connected to a vehicle.
