Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0027] Referring to the accompanying drawings, an electric vehicle charging and discharging assembly includes a charging and discharging gun 100, a discharging plug 200, and an adapter 300.

[0028] The charging / discharging gun 100 includes a vehicle-end gun head 101, a cable 102, and a charging / discharging plug 103. The vehicle-end gun head 101 is used to connect to the vehicle when charging or discharging from the vehicle. One end of the cable 102 is connected to the vehicle-end gun head 101, and the other end is connected to the charging / discharging plug 103. The charging / discharging plug 103 is a 16A plug. When the charging / discharging plug 103 is plugged into a charging station and used alone, the charging / discharging gun 100 operates in 16A charging mode.

[0029] The charging / discharging plug 103 includes a plug body 103-1, L / N / PE power contacts and signal contacts 103-4 disposed at the plug contact end, and a locking mechanism disposed on the side of the plug body 103-1. The signal contacts 103-4 are used to contact signal terminals adapted on the discharge plug 200 and adapter 300 to identify the charging or discharging mode and the charging current. Two signal contacts 103-4 are provided and are flush with the end face of the plug contact end.

[0030] The locking mechanism is located on one side or opposite sides of the plug body 103-1. In this embodiment, the locking mechanism is located on opposite sides of the plug body 103-1. Figure 4 As shown, the locking mechanism includes a button 103-2 and a locking hook 103-3. The locking hook 103-3 is slidably installed inside the plug body 103-1. One end of the locking hook 103-3 is a hook body for locking, and the other end is used to connect with the button 103-2. A spring or spring sheet for resetting the locking hook 103-3 is installed inside the plug body 103-1. The hook body of the locking hook 103-3 protrudes from the side of the plug body 103-1. The button 103-2 is installed in a key hole on the side of the plug body 103-1. After pressing the button 103-2 from the outside in, the spring or spring sheet is compressed by the locking hook 103-3, and the hook body of the locking hook 103-3 retracts into the plug body 103-1, thus releasing the locking mechanism.

[0031] like Figure 5 As shown, the discharge socket 200 is used to connect with the charging / discharging plug 103. In this case, the vehicle discharges electricity, and the electrical devices draw power from the discharge socket 200 to meet different power needs. The socket panel 201 of the discharge socket 200 has one discharge input position 202 and multiple discharge output positions. The discharge input position 202 is used to connect with the charging / discharging plug 103 to input current for vehicle discharge. The discharge input position 202 has a groove, and a first locking groove 202-1 is provided on the side of the groove for locking with the locking hook 103-3 on the charging / discharging plug 103. Two first spring signal pins 202-2 are provided in the groove, protruding from the bottom of the groove, for elastic contact with the signal contact 103-4 on the charging / discharging plug 103 to enable the vehicle and the charging / discharging gun 100 to identify the discharge mode. The discharge output positions include multiple sockets and multiple USB interfaces. In this embodiment, the discharge output position includes a first socket 203, a second socket 204, and a third socket 205. The first socket 203 outputs a 16A current, while the second socket 204 and the third socket 205 each output a 10A current, thus meeting the power supply needs of different electrical devices. In this embodiment, the USB interface 206 includes a Type-A port and a Type-C port to meet the power requirements of devices powered via USB.

[0032] It is understood that the number and type of sockets for the discharge output position or the number and type of USB interfaces on the discharge power strip 200 can be set according to actual conditions, and are not the set number and type described in this embodiment.

[0033] like Figure 6As shown, the adapter 300 is used to realize the 10A charging mode of the vehicle. The input end of the adapter 300 is provided with an adapter groove 301 for insertion into the charging plug 103. In addition to the socket for connecting the charging plug 103, the adapter groove 301 is also provided with two second spring signal pins 302. The second spring signal pins 302 protrude from the bottom of the adapter groove 301 and are used to elastically contact the signal contact 103-4 on the charging plug 103 to realize the vehicle and the charging gun 100 to identify the charging mode and charging current. The inner side of the adapter groove 301 is also provided with a second locking groove 303 for locking with the locking hook 103-3 on the charging plug 103. The output end of the adapter 300 is provided with L / N / PE power plugs for plugging into the charging pile to charge the vehicle.

[0034] The following is combined Figure 7-9 The circuit setup on the charging / discharging plug, discharge strip, and adapter is explained.

[0035] like Figure 7 As shown, the circuit inside the charging / discharging plug 103 has pins S and CC1, which are respectively connected to two signal contacts 103-4 on the charging / discharging plug 103. Pin S is used to connect to the identification circuit on the circuit board inside the vehicle-side gun head 101, so that the circuit board identifies the current working mode. Pin CC1 is used to connect to the identification circuit on the vehicle, so that the vehicle identifies the current working mode. The working modes include 16A charging mode, 10A charging mode, and discharging mode. The circuit inside the charging / discharging plug 103 also has a normally open over-temperature protection switch 400. Under normal operation, the normally open over-temperature protection switch 400 is in the open circuit state. When an over-temperature condition occurs, the normally open over-temperature protection switch 400 closes.

[0036] like Figure 8 As shown, the circuit within the discharge socket 200 includes pins S and CC1, which are respectively connected to the two first spring signal pins 202-2 of the discharge input position 202. A first identification resistor R1 is connected to the branch containing pin CC1, and pin CC1 is used to connect to the identification circuit on the vehicle, allowing the vehicle to identify the current operating mode. A second identification resistor R2 is connected to the branch containing pin S, and pin S is used to connect to the identification circuit on the circuit board inside the vehicle-end nozzle 101, allowing the circuit board to identify the current operating mode. Within the discharge socket 200, the first identification resistor R1 and the second identification resistor R2 are connected in parallel. Furthermore, a normally open over-temperature protection switch 400 is also connected in parallel to the second identification resistor R2.

[0037] After the charging / discharging plug 103 and the discharging socket 200 are connected, the pin S in the two circuits is connected through the signal contact 103-4 and the first spring signal pin 202-2, and the pin CC1 is connected through the signal contact 103-4 and another first spring signal pin 202-2.

[0038] like Figure 9 As shown, the circuit within the adapter 300 includes pins S and CC1, which are respectively connected to two second spring signal pins 302. A third identification resistor R3 is connected to the branch containing pin CC1, and pin CC1 is used to connect to the vehicle's identification circuit for the vehicle to identify the current operating mode. A fourth identification resistor R4 is connected to the branch containing pin S, and pin S is used to connect to the identification circuit on the circuit board inside the vehicle-end gun head 101 for the circuit board to identify the current operating mode. Inside the adapter, the third identification resistor R3 and the fourth identification resistor R4 are connected in parallel. Furthermore, a normally open over-temperature protection switch 400 is also connected in parallel to the fourth identification resistor R4.

[0039] After the charging / discharging plug 103 and the adapter 300 are connected, pin S in the two circuits is connected through the signal contact 103-4 and the second spring signal pin 302, and pin CC1 is connected through the signal contact and the second spring signal pin 302.

[0040] In the circuits of adapter 300 and discharge plug 200, the first identification resistor R1, the second identification resistor R2, the third identification resistor R3 and the fourth identification resistor R4 have different resistance values, so the total resistance of the circuit is also different to meet the current requirements of charging and discharging.

[0041] This invention distributes the identification resistors into different units (charge / discharge plug 103, discharge socket 200, and adapter 300), which can form a standard resistance value after being plugged in to meet the charging and discharging requirements.

[0042] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
