[0002] With the popularity of electric vehicles and the rise of outdoor camping activities, the discharge function has become one of the essential functions of electric vehicles. The external discharge of electric vehicles requires the DC power of the power battery to be inverted into AC power. The commonly used solution in the industry is to configure a bidirectional OBC (on-board charger) and use the AC charging socket as a discharge interface to achieve the discharge function.
[0003] In order to realize the switch control and current overload protection functions of the entire discharge circuit, it is necessary to configure relays and fuses in the discharge circuit.

[0013] As a further improvement, the relay is mounted on the PCB board and the fuse is mounted on the socket body.
[0014] The beneficial effect is that the fuse is arranged as a part independent of the socket body, so that the fuse can be replaced separately.

[0046] In order to solve the problem that relays and fuses of different specifications in the discharge circuit affect the standardization of OBC (on-board charger), the basic technical concept of the utility model is to separate the relay and fuse from the OBC, connect them in the charging socket, and connect them with the OBC in the same discharge circuit to achieve switch control and current overload protection.
[0047] The present invention is further described in detail below in conjunction with the embodiments.
[0048] Specific embodiment 1 of the charging socket provided by the utility model:
[0049] The purpose of this embodiment is to provide a charging socket in which a relay is integrated on a PCB board and a fuse is integrated on the socket body. Figure 1 and Figure 2As shown, the charging socket in this embodiment includes a socket body 1, on which is provided a socket portion for connecting an AC charging plug, and is also provided with a connection interface for electrically connecting to the OBC, thereby forming a charging circuit of the charging socket and the OBC. The specific charging circuit and the structure of the connection interface are consistent with the prior art and are not described in detail.
[0050] like Figure 3 As shown, the socket body 1 is provided with a PCB board 6 at the position of the socket tail 3. Specifically, the PCB board 6 can be installed on the socket body 1 through the PCB mounting holes 9 on the PCB board 6 with screws or rivets. The connection interface for electrical connection with the OBC is provided on the PCB board 6. A relay 7 is integrated and installed on the PCB board 6. The relay 7 can be directly welded on the PCB board 6 and electrically connected to the internal circuit of the PCB board 6, thereby realizing its electrical connection with the OBC. Figure 4 As shown, a detachable fuse box 2 is also installed on the socket body 1. Specifically, the fuse box 2 can be installed on the socket body 1 by installing screws or rivets through the fuse box installation hole 10 on the fuse box 2. A fuse 5 is installed in the fuse box 2. The fuse 5 is connected to the same discharge circuit through the wire 4 and the relay 7. Specifically, the fuse 5 can be directly connected to the relay 7 through the wire 4, and can also be connected to the PCB board 6. In other embodiments, the fuse box 2 may not be provided, and the fuse 5 can be directly fixed on the socket body 1 by soldering.
[0051] The circuit connection structure of each part of this embodiment when in use is as follows Figure 5 As shown, the charging socket is connected to the OBC, the OBC is connected to the power battery pack, and the external power unit is connected to the charging socket to form a complete discharge circuit. Since the charging socket includes a relay and a fuse, and the relay and the fuse are connected to the discharge circuit, the switch control and current overload protection of the entire circuit are realized.
[0052] Compared with the prior art, the charging socket in this embodiment has the functions of switch control and current overload protection, which meets the use needs. At the same time, there is no need to reserve installation space for relays and fuses in the OBC, which facilitates the standardization of the OBC.
[0053] In addition, in this embodiment, the fuse 5 is independently arranged on the socket body 1, so that in the subsequent use process, if the fuse 5 burns out, the fuse 5 can be replaced separately, which is more efficient.
[0054] The specific embodiment 2 of the charging socket provided by the utility model mainly differs from the embodiment 1 in that: in the embodiment 1, the fuse is installed on the socket body, and the relay is integrated on the PCB board. The purpose of this embodiment is to provide a charging socket with the relay and the fuse swapped. Specifically, the fuse in this embodiment is integrated on the PCB board, the relay is installed on the socket body, and the relay and the fuse are connected by a wire. In this case, the same switch control and current overload protection functions can be achieved.
[0055] The specific embodiment 3 of the charging socket provided by the utility model is different from the embodiment 1 mainly in that: in the embodiment 1, the fuse is set on the socket body, and the relay is integrated on the PCB board. The purpose of this embodiment is to provide a charging socket in which both the relay and the fuse are integrated on the PCB board. Specifically, Figure 6 As shown, the relay 7 and the fuse 5 can be connected to the PCB board 6 by screws or welding, plugging, hot riveting, etc. At this time, the relay 7 and the fuse 5 are both electrically connected to the PCB board 6, and the PCB board 6 is connected to the OBC through the wire 4 and the terminal 8 for transfer. At this time, while realizing the functions of switch control and current overload protection, the relay 7 and the fuse 5 can also be integrated and installed on the PCB board 6 first, which has high installation efficiency.
[0056] Regarding the connection form of the relay and the fuse in this embodiment, as a preferred solution, the relay and the fuse can be connected through the internal circuit of the PCB board, so that the integration effect is better. Of course, in other implementations, the relay and the fuse can also be connected through a wire.
[0057] The specific embodiment 4 of the charging socket provided by the utility model is different from the embodiment 1 mainly in that: in the embodiment 1, the fuse is arranged on the socket body, and the relay is integrated on the PCB board. The purpose of this embodiment is to provide a charging socket in which both the relay and the fuse are arranged on the socket body. Specifically, Figure 7 As shown, similar to the embodiment 1, a detachable fuse box 2 is installed on the socket body, and the relay 7 and the fuse 2 are both installed on the fuse box 2 and connected to the PCB board through the wire 4. As an implementable solution, an independent circuit board can be set in the fuse box 2, and the relay 7 and the fuse 5 can be electrically connected to the circuit board in the fuse box 2. As another implementable solution, an independent circuit board may not be set in the fuse box 2, and the relay 7 and the fuse 5 can be directly connected by wires. In this case, there is no need to modify the PCB board, and it is convenient to repair and replace the fuse.
[0058] In this embodiment, the socket body 1 may not even have a PCB board, and the interfaces of each circuit are connected by wires, which will increase the number of wires inside the socket body 1, but can achieve the same switching and overload protection functions.

[0060] The vehicle includes a power battery, an on-board charger and a charging socket. The charging socket is the charging socket described in any one of Embodiments 1 to 4 of the above-mentioned charging socket, which will not be described in detail here.
[0061] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein by equivalents.
