The flip cover 70 can be buckled to the socket panel 102 after flipping, so as to cover the outside of the socket panel 102, thereby achieving a certain protection and waterproof effect on the socket panel 102. The above-mentioned switch door assembly 20 is arranged on the inner side of the socket panel 102, and the plug-in is inserted from the socket panel 102 and electrically connected to the conductive terminal structure 50 after passing through the switch door assembly 20.

When the discharge socket of the present application is in use, the insertion and removal of the connector is monitored by the switch door assembly 20 provided in the seat body 10, and the monitored plug-in and pull-out signals are transmitted to the external control module, and then the external control module can control the power supply state of the power cord 40 according to the received plug-in and pull-out signals, so that the power supply state of the discharge socket can be intelligently switched according to the insertion and removal of the connector, so as to prevent the discharge socket from being unable to be powered off in time after use, which may lead to the risk of electric shock; in addition, when the discharge socket of the present application is used for discharge outside the vehicle, there is no need to separately configure a dedicated discharge gun, which is convenient to use.

In one embodiment, as shown in Figures 2, 6 and 7, the switch door assembly 20 includes a supporting base 201 detachably connected to the socket panel 102, and the side of the supporting base 201 facing the socket panel 102 has a sliding cavity 202 formed by an inward depression, and at least one baffle 30 that can slide along a predetermined path when the connector is inserted is arranged in the sliding cavity 202, and the bottom surface and/or the side surface of the sliding cavity 202 are provided with at least one sensing structure electrically connected to the external control module, and the baffle 30 can abut against the sensing structure during the process of sliding along the predetermined path. Furthermore, the sensing structure includes a force transmission rod 204 and a micro switch 205 electrically connected to an external control module. A guide hole 203 is provided through the bottom surface and/or side surface of the sliding cavity 202. A force transmission rod 204 with a top protruding from the bottom surface and/or side surface of the sliding cavity 202 is retractably provided in the guide hole 203. The micro switch 205 is arranged on a side of the force transmission rod 204 away from the supporting seat 201. When the baffle 30 slides along a predetermined path, it can abut against the micro switch 205 through the force transmission rod 204.

The control principle of the present application is as follows: As shown in FIG5 , the micro switch 205 is electrically connected to the input end of the external control module through the signal line 60, the output end of the external control module is electrically connected to the power supply module, and the power supply module is electrically connected to the conductive terminal structure through the power line 40, and after the sensing end of the micro switch 205 is abutted by the force transmission rod 204, the monitored sensing signal (plug and unplug signal) is transmitted to the external control module, and then the external control module controls the power supply module to change the power supply state of the power line 40. It should be noted here that the external control module and the power supply module mentioned in this embodiment can be, for example, the controller and the power supply module of the whole vehicle, respectively.

In this embodiment, as shown in FIG8 , the middle part of the force transmission rod 204 has a protruding stop ring 2041, and a first return spring 207 is provided between the stop ring 2041 and the micro switch 205.

After the force transmission rod 204 is pressed, the crimping portion 2043 at the bottom of the force transmission rod 204 abuts against the sensing end of the micro switch 205. The setting of the stop ring 2041, the protruding portion 2042 and the crimping portion 2043 can ensure the stability of the force transmission rod 204 when it is pressed, and prevent dislocation and other unexpected situations, which result in the inability to further press the sensing end of the micro switch 205.

In one embodiment, as shown in Figures 2 and 3, the conductive terminal structure 50 is arranged on a side of the supporting base 201 away from the socket panel 102; the conductive terminal structure 50 includes a conductive terminal 501 with a power cord 40 crimped at one end, and a conductive spring 502 embedded in the supporting base 201 on the side away from the socket panel 102, and the end of the conductive terminal 501 that is not crimped with the power cord 40 is conductively connected to the conductive spring 502.

At the same time, the socket panel 102 and the sliding cavity 202 are correspondingly provided with a first socket 206 for the connector to pass through. The connector passes through the first socket hole 206 provided on the socket panel 102 and the sliding cavity 202 and is electrically connected to the conductive spring sheet 502 of the conductive terminal structure 50, thereby achieving a stable electrical connection.

In one embodiment, the baffle 30 covers or exposes the first socket 206 during the process of sliding in the sliding cavity 202, as follows: when the connector is not inserted, the baffle 30 covers the outside of the first socket 206, and when the connector is inserted, the baffle 30 slides along a predetermined path to expose the first socket 206, thereby achieving the purpose of secondary protection and further preventing the risk of electric shock when the connector is not inserted.

As shown in Figures 6 and 7, the baffle 30 specifically includes a first baffle 301 and a second baffle 302 that are relatively arranged on the bottom surface of the sliding cavity, and at least one second return spring 303 is arranged between the first baffle 301 and the second baffle 302. The second return spring 303 provides a retaining force to the first baffle 301 and the second baffle 302 so that the two (the first baffle 301 and the second baffle 302) are respectively abutted against the side of the sliding cavity 202. At this time, the first baffle 301 and the second baffle 302 cover the outside of the first socket 206.

In order to ensure the stability of the first baffle 301 and the second baffle 302 when sliding, as shown in Figure 6, a support rod 304 for installing the second return spring 303 is correspondingly arranged on the opposite side walls of the first baffle 301 and the second baffle 302. The support rod 304 can be cylindrical (see Figure 6 for details) or prismatic (not shown in the figure), and the second return spring 303 is sleeved on the outside of the support rod 304.

The bottom surface of the sliding cavity 202 is also provided with a guide groove 305 for assisting the first baffle plate 301 and the second baffle plate 302 to slide along a predetermined path therein, and the bottoms of the first baffle plate 301 and the second baffle plate 302 are respectively provided with a first slider 306 and a second slider 307 matching the guide groove 305. The first slider 306 and the second slider 307 match the shape of the guide groove 305 and can move freely in the guide groove 305. Further, the guide hole 203 is located in the guide groove 305. Inside, the first slider 306 and the second slider 307 are both provided with a crimping bevel 308 for pressing the force transmission rod 204. When the first baffle plate 301 and the second baffle plate 302 move in the guide groove 305, the force transmission rod 204 is pressed by the crimping bevel 308 provided on the first slider 306 and the second slider 307 to prevent the baffle plate 30 from interfering with the force transmission rod 204 and failing to be pressed.

In one embodiment, the plug connector is a three-pin plug or a two-pin plug. In this embodiment, the three-pin plug includes two live pins and one ground pin, and correspondingly, the first baffle 301 and the second baffle 302 need to be provided with corresponding inclined structures. Specifically, as shown in FIG6 and FIG7, the top end surface of one of the first baffle 301 and the second baffle 302 has a first inclined surface 309 that matches the live pin, and the top end surface of the other has a second inclined surface 310 that matches the pin of the two-pin plug, and the middle part of the other also has a second plug hole 311 for the ground pin in the three-pin plug to pass through.

The following takes the example that the first inclined surface 309 is arranged on the first baffle 301, and the second inclined surface 310 and the second plug hole 311 are arranged on the second baffle 302 to illustrate the technical solution of the present application:

1) When the plug connector is a two-hole plug, it needs to be inserted from the second baffle 302. During the insertion process, due to the existence of the second inclined surface 310, the second baffle 302 will slide inward along the guide groove 305 after receiving the vertical downward force of the pin of the two-hole plug, so that the first plug hole 206 is exposed, so that the pin of the two-hole plug can be smoothly inserted into the first plug hole 206, and achieve conductive connection with the conductive terminal structure 50. At the same time, during the process of the second baffle 302 sliding inward along the guide groove 305, the force transmission rod 204 can be pressed and the bottom end of the force transmission rod 204 can be abutted against the micro switch 205, thereby realizing power transmission of the power cord 40 and the conductive terminal structure 50.

2) When the plug connector is a three-pin plug, it needs to be inserted from the first baffle 301. During the insertion process, due to the existence of the first inclined surface 309, the first baffle 301 will slide inward along the guide groove 305 after receiving the vertical downward force of the two live pins of the three-pin plug, so that the first plug hole 206 is exposed, while the second baffle 302 does not move because it is not subjected to force, and the second plug hole 311 on the second baffle 302 is always in an exposed state, so that the two live pins and one ground pin of the three-pin plug can be smoothly inserted into the first plug hole 206 and the second plug hole 311, and then achieve conductive connection with the conductive terminal structure 50. At the same time, during the process of the first baffle 301 sliding inward along the guide groove 305, the force transmission rod 204 can be pressed and the bottom end of the force transmission rod 204 can be abutted against the micro switch 205, thereby realizing power transmission of the power cord 40 and the conductive terminal structure 50.
