[0043] Specifically, as shown in FIGS. 1 and 4, the discharge connection device 100 is used in a vehicle, and the vehicle includes an electrical accumulator and a first connection part 200, and the electrical accumulator and the first connection part 200 are electrically connected. The second connection part 2 is arranged at one end of the main body part 1, and is used to connect with the first connection part 200.

The current in the electrical accumulator of the vehicle transmitted by the second connection part 2 is transmitted to the plug 300 of the electrical equipment via the plug-in part 31 on the third connection part 3, so as to transmit the current of the electrical accumulator of the vehicle to the electrical equipment outside the vehicle, and the user can lead the electrical energy in the electrical accumulator to the electrical equipment outside for use.

[0045] As shown in FIG. 3, FIG. 8 and FIG. 9, the protective cover 4 is used to open or cover the plug-in part 31 and the plug 300, when the plug 300 is connected with the plug-in part 31, the protective cover 4 is configured to trigger the first switch 32 when covering the plug-in part 31 and the plug 300, and the power storage device supplies power to the electrical equipment.

[0046] It can be understood that when the protective cover 4 covers the plug-in part 31 and the plug 300, the first switch 32 is triggered, the circuit between the power storage device and the electrical equipment is conducted, and the electrical equipment is powered on; when the protective cover 4 opens the plug-in part 31 and the plug 300, the first switch 32 is in open circuit, the circuit between the power storage device and the electrical equipment is disconnected, and the electrical equipment is not powered on. The user must cover the plug-in part 31 and the plug 300 with the protective cover 4 before taking power, which avoids the leakage caused by the sudden rain during the process of taking power from the power storage device of the vehicle, and has the function of protecting the electrical safety of the power storage device of the vehicle from discharging to the outside.

[0047] According to the discharge connection device 100 of the embodiment of the present application, the power storage device and the electrical equipment on the vehicle are connected through the discharge connection device 100, and the user can take the electrical energy in the power storage device to the external electrical equipment. And the protective cover 4 is used to open or cover the plug-in part 31 and the plug 300, when the plug 300 is connected with the plug-in part 31, the user must cover the plug-in part 31 and the plug 300 with the protective cover 4 before taking power, which avoids the leakage caused by the sudden rain during the process of taking power from the power storage device of the vehicle, and has the function of protecting the electrical safety of the power storage device of the vehicle from discharging to the outside.

[0048] In the present application, the second connecting part 2 is arranged at one end of the length direction (a direction shown in FIG. 1) of the main body part 1, the third connecting part 3 is arranged at the other end of the length direction of the main body part 1, and the first connecting part 200 and the second connecting part 2 are arranged oppositely, so that the connection of the discharge connection device 100 with the power storage device of the vehicle and the connection of the discharge connection device 100 with the external electrical equipment are more reliable.

[0049] In some embodiments of the present application, the first switch 32 is arranged on the third connecting part 3, so that the protective cover 4 can better contact the first switch 32 when covering the plug-in part 31 of the third connecting part 3, and trigger the first switch 32.

[0050] In some embodiments of the present application, as shown in FIG. 1, the inner wall of the protective cover 4 is provided with a triggering structure 41, the protective cover 4 covers the plug-in part 31 and the plug 300, the triggering structure 41 abuts against the first switch 32, and is used to trigger the first switch 32. The abutting and disengaging manner of the protective cover 4 and the first switch 32 is relatively simple, and when the protective cover 4 starts to open the plug-in part 31 and the plug 300, the triggering structure 41 and the first switch 32 are immediately disengaged, the circuit between the power storage device and the electrical equipment is disconnected, and the electrical equipment is not powered on, which can better avoid the electric shock caused by the sudden rain in the process of taking power from the power storage device of the vehicle, and has the function of forcibly protecting the electrical safety of the power storage device of the vehicle to discharge to the outside.

[0051] In some embodiments of the present application, as shown in FIGS. 1 and 2, one end of the protective cover 4 is rotatably arranged on the third connecting part 3 or the main body part 1. The process of the protective cover 4 from covering the plug-in part 31 and the plug 300 to opening the plug-in part 31 and the plug 300 can be relatively simple, and the process of the protective cover 4 from opening the plug-in part 31 and the plug 300 to covering the plug-in part 31 and the plug 300 can be relatively simple.

[0052] Specifically, as shown in FIGS. 2 and 7, the outer peripheral wall of the third connecting part 3 is provided with a first lug 36, and the peripheral direction of the protective cover 4 is provided with a second lug 43, the first lug 36 and the second lug 43 are rotatably connected by a pin or a bolt, and the connection of the protective cover 4 and the third connecting part 3 is relatively simple.

[0053] In the up-down direction (as shown in FIG. 1), the first lug 36 and the second lug 43 can be arranged on the upper half of the protective cover 4 and the third connecting part 3, and specifically, can be arranged at any position in the direction of 180° from horizontal left to horizontal right, thereby increasing the installation space of the protective cover 4. The protective cover 4 can form a sealing surface with the first connecting surface 33, so that the connection of the protective cover 4 and the first connecting surface 33 is relatively simple and reliable.

[0054] In addition, the protective cover 4 can form a containing space with the main body part 1 or the third connecting part 3 of the discharge connecting device 100, and the containing space is convenient for containing the plug 300 of the electrical equipment inserted into the plug-in part 31.

[0055] In some embodiments of the present application, as shown in FIGS. 7 and 8, the third connecting part 3 has a first connecting surface 33, and the first connecting surface 33 is arranged on the axial end surface of the discharge connecting device 100. The plug-in part 31 can be arranged on the first connecting surface 33, so that the plug-in part 31 is located on the axial end surface of the discharge connecting device 100, and the plug-in process of the plug 300 and the plug-in part 31 is relatively smooth and convenient.

[0056] Further, when the first connecting part 200 is connected with the second connecting part 2, the first connecting surface 33 is a vertical surface, which can avoid the plug 300 from being subjected to a vertical downward component force when the plug 300 is inserted into the first connecting surface 33, can avoid the plug-in part 31 from being subjected to a load break, and can increase the reliability of the connection between the plug-in part 31 and the plug 300.

[0057] Alternatively, the first connecting surface 33 is upwardly inclined at an angle A in the axial direction of the discharge connecting device 100, and 0 < A ≤ 10° is satisfied. It can be understood that the angle A at which the first connecting surface 33 is upwardly inclined can be 0, 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, 8°, 8.5°, 9°, 9.5°, or 10°. The angle A at which the first connecting surface 33 is upwardly inclined is not less than 0°, which can avoid the plug 300 from being subjected to a vertical downward component force when the plug 300 is inserted into the plug-in part 31, can avoid the plug-in part 31 from being subjected to a load break, and can increase the reliability of the connection between the plug-in part 31 and the plug 300; the angle A at which the first connecting surface 33 is upwardly inclined is not greater than 10°, which can avoid the angle A at which the first connecting surface 33 is upwardly inclined from being too large, and can make the process of inserting the plug 300 into the plug-in part 31 more convenient.

[0058] In some embodiments of the present application, as shown in FIG. 4, the second connecting part 2 has a second connecting surface 21, and the first connecting surface 33 is arranged on the axial end surface of the discharge connecting device 100, and the normal line of the first connecting surface 33 is parallel to the normal line of the second connecting surface 21. The first connecting surface 33 and the second connecting surface 21 of the discharge connecting device 100 are parallel, the first connecting part 200 and the second connecting part 2 are parallel, the structure of the discharge connecting device 100 is simple, the volume is small, the space occupied is small, and the use is convenient. Moreover, when the first connecting part 200 cooperates with the second connecting surface 21, the cooperation between the second connecting surface 21 and the first connecting part 200 is more convenient.

[0059] In addition, before or after the second connecting part 2 of the discharge connecting device 100 and the first connecting part 200 of the vehicle are plugged, the connection between the plug 300 and the plug-in part 31 can ensure that the interface of the plug 300 and the first connecting part 200 is subjected to a horizontal force, and the port of the first connecting part 200 is not subjected to a force, so that the use of the discharge connecting device 100 is more durable and reliable.

[0061] It can be understood that, as shown in Figure 10, the connection between the CC and the PE is the circuit connected by the discharging connection device 100 and the vehicle, and the connection of the discharging connection device 100 with the vehicle has the following five states:

[0062] State 1: When the first connection part 200 of the vehicle and the discharging connection device 100, and the plug 300 of the electrical equipment in the third connection part 3 are not inserted into the plug-in part 31, the vehicle detects that the resistance between the CC and the PE is R4'+RC', and the vehicle displays that the first connection part 200 of the vehicle has a gun insertion signal, but does not start discharging;

[0063] State 2: When the first connection part 200 of the vehicle and the discharging connection device 100, and only the plug 300 of the electrical equipment in the third connection part 3 is inserted into the plug-in part 31, the plug 300 of the electrical equipment closes one of the switches S1' or S2', the vehicle detects that the resistance between the CC and the PE is R4'+RC', and the vehicle displays that the first connection part 200 of the vehicle has a gun insertion signal, but does not start discharging;

[0064] State 3: When the first connection part 200 of the vehicle and the discharging connection device 100, and the plug 300 of the electrical equipment in the third connection part 3 is inserted into the plug-in part 31, and then the protective cover 4 is closed, the protective cover 4 closes the remaining one of the switches S1' or S2', the vehicle detects that the resistance between the CC and the PE is RC', and the vehicle displays that the discharging connection device 100 and the plug 300 are completely connected, and discharging is started;

[0065] State 4: When the use of electricity is over, the user opens the protective cover 4, the protective cover 4 opens one of the switches S1' or S2', the vehicle detects that the resistance between the CC and the PE is R4'+RC', the discharging is ended, and the user pulls out the plug 300 of the electrical equipment, and the plug-in part 31 of the discharging connection device 100 does not have a load breaking phenomenon, which improves the service life of the plug-in part 31;

[0066] State 5: When the use of electricity is over, the user first presses S3, the vehicle detects that the resistance between the CC and the PE is R4'+RC', the discharging is ended, and the structure of the switch is consistent with the description of the alternating current or direct current charging gun in the standard IEC 62196 and GB / T 20234 series standards, but when used in the discharging connection device 100, the S3 switch can be selectively installed.

[0067] The second connection part 2 of the discharging connection device 100 and the first connection part 200 of the vehicle include the national standard, European standard and American standard interface defined in the IEC 62196 and GB / T 20234 series standards. The type of the plug-in part 31 on the third connection part 3 of the discharging connection device 100 should include the socket type in the IEC TR 60083 and GB / T 1002 series standards.

[0068] In some embodiments of the present application, as shown in FIG. 1 and FIG. 6, the protective cover 4 is provided with a wire slot 42, which is used for the wire harness 400 connected with the plug 300 to pass out of the protective cover 4, so that the wire harness 400 has a reliable passing-out position after the plug 300 of the electrical equipment is connected with the plug-in part 31, thereby increasing the reliability of the plug 300 of the electrical equipment.

[0069] In some embodiments of the present application, as shown in FIG. 3 and FIG. 6, when the protective cover 4 covers the plug-in part 31 and the first connecting part 200 and the second connecting part 2 are connected, one end of the length direction of the wire slot 42 is located on the surface of the protective cover 4 opposite to the plug-in part 31, and the other end extends downward to the opening of the protective cover 4. This can prevent rainwater from contacting the plug-in part 31 when the wire harness 400 is connected to the tail of the plug 300 or the wire harness 400 is perpendicular downward relative to the plug-in direction of the plug 300, and the wire harness 400 can pass out of the wire slot 42 when the wire harness 400 is connected to the tail of the plug 300 or the wire harness 400 is perpendicular downward relative to the plug-in direction of the plug 300, thereby making the discharge connecting device 100 more widely applicable.

One of the first magnetic attraction member and the second magnetic attraction member is a magnet, the other of the first magnetic attraction member and the second magnetic attraction member is a magnet or a metal, and the magnet of the first magnetic attraction member and the second magnetic attraction member can also be an electromagnet. The first magnetic attraction member and the second magnetic attraction member can be attracted to each other to provide a certain holding force.

[0071] The protective cover 4 is also provided with a fixing structure, and the first magnetic attraction member is arranged on the fixing structure of the protective cover 4, which can reduce the distance between the first magnetic attraction member and the second magnetic attraction member, and facilitate the cooperation between the first magnetic attraction member and the second magnetic attraction member.

[0072] In addition, the holding force between the first magnetic attraction member and the second magnetic attraction member can increase the cooperation between the first switch 32 and the trigger structure 41 on the protective cover 4, thereby increasing the reliability of the cooperation between the protective cover 4 and the first switch 32.
