For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Reference below Figure 1-Figure 10 A discharge connection device 100 according to an embodiment of the present invention is described.

[0045] like Figure 1 and Figure 6 As shown, the discharge connection device 100 according to the embodiment of the utility model includes a main body 1, a second connection part 2, a third connection part 3, a first switch 32 and a protective cover 4.

[0046] Specifically, Figure 1 and Figure 4As shown, the discharge connection device 100 is used for a vehicle, and the vehicle includes a battery and a first connection part 200, and the battery is electrically connected to the first connection part 200. The second connection part 2 is provided at one end of the main body 1, and is used to connect with the first connection part 200. The current in the battery of the vehicle can be transferred to the second connection part 2 of the discharge connection device 100 via the first connection part 200, and the discharge connection device 100 can transfer the current in the battery of the vehicle to the outside.

[0047] like Figure 2 and Figure 7 As shown, the third connection part 3 is arranged at the other end of the main body 1, and the third connection part 3 is provided with a plug part 31 for connecting with a plug 300 of an electric device. The current in the battery of the vehicle transmitted by the second connection part 2 is transmitted to the plug 300 of the electric device via the plug part 31 on the third connection part 3, thereby transmitting the current of the battery of the vehicle to the electric device outside the vehicle, and the user can lead the electric energy in the battery to the external electric device for use.

[0048] like Figure 3 , Figure 8 and Fig. 9 As shown, the protective cover 4 is used to open or cover the plug-in portion 31 and the plug 300. When the plug 300 is connected to the plug-in portion 31, the protective cover 4 is configured to trigger the first switch 32 when covering the plug-in portion 31 and the plug 300, and the storage device supplies power to the electrical device.

[0049] It is understandable that when the protective cover 4 covers the plug-in portion 31 and the plug 300, the first switch 32 is triggered, the circuit between the battery and the electrical equipment is connected, and the electrical equipment is powered; when the protective cover 4 opens the plug-in portion 31 and the plug 300, the first switch 32 is in an open circuit, the circuit between the battery and the electrical equipment is disconnected, and the electrical equipment is not powered. The user must cover the plug-in portion 31 and the plug 300 with the protective cover 4 before drawing electricity, so as to avoid leakage caused by sudden wind and rain when the user draws electricity from the vehicle's battery, and has the function of forcibly protecting the vehicle's battery from discharging outwards to ensure the safety of electricity use.

[0050] According to the discharge connection device 100 of the embodiment of the utility model, the user can lead the electric energy in the electric storage device to the external electric storage device for use by connecting the electric storage device and the electric consumption equipment on the vehicle through the discharge connection device 100. The protective cover 4 is used to open or cover the plug-in portion 31 and the plug 300. When the plug 300 is connected to the plug-in portion 31, the user must cover the plug-in portion 31 and the plug 300 with the protective cover 4 before drawing electricity, so as to avoid leakage caused by sudden wind and rain when the user draws electricity from the electric storage device of the vehicle, and has the function of forcibly protecting the electric storage device of the vehicle from discharging electricity to the outside.

[0051] In the present invention, the second connecting portion 2 is arranged in the length direction of the main body 1 (such as Figure 1 The third connection part 3 is arranged at one end of the main body 1 in the length direction, and the first connection part 200 and the second connection part 2 are arranged opposite to each other, so that the connection between the discharge connection device 100 and the vehicle's battery and the connection between the discharge connection device 100 and the external electrical equipment are more reliable.

[0052] In some embodiments of the present invention, the first switch 32 is disposed on the third connection portion 3 , so that when the protective cover 4 covers the plug-in portion 31 of the third connection portion 3 , it can better contact with the first switch 32 , thereby triggering the first switch 32 .

[0053] In some embodiments of the present invention, Figure 1 As shown, a trigger structure 41 is provided on the inner wall of the protective cover 4, and the protective cover 4 covers the state of the plug-in portion 31 and the plug 300, and the trigger structure 41 abuts against the first switch 32 to trigger the first switch 32. The abutment and disengagement of the protective cover 4 and the first switch 32 can be made simpler, and when the protective cover 4 begins to open the plug-in portion 31 and the plug 300, the trigger structure 41 and the first switch 32 immediately disengage, the circuit between the battery and the electrical equipment is disconnected, and the electrical equipment is not powered, which can better prevent leakage caused by sudden wind and rain when the user is drawing power from the battery of the vehicle, and has the function of forcibly protecting the safety of the battery of the vehicle from discharging outward.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, one end of the protective cover 4 is rotatably arranged on the third connecting part 3 or the main body 1. This can make 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 relatively simple, and can make 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 relatively simple.

[0055] Specifically, Figure 2 and Figure 7 As shown, a first lug 36 is provided on the outer peripheral wall of the third connecting portion 3, and a second lug 43 is provided in the circumferential direction of the protective cover 4. The first lug 36 and the second lug 43 are rotatably connected by pins or bolts, and the connection between the protective cover 4 and the third connecting portion 3 is relatively simple.

[0056] In the up and down direction (such as Figure 1 The first lug 36 and the second lug 43 can be arranged on the upper part of the protective cover 4 and the third connecting portion 3, specifically, they can be arranged at any position in the 180° direction from horizontal left to horizontal right, so as to increase 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 between the protective cover 4 and the first connecting surface 33 is relatively simple and reliable.

[0057] In addition, the protective cover 4 can form a receiving space with the main body 1 or the third connecting part 3 of the discharge connection device 100 , and the receiving space is convenient for receiving the plug 300 of the electric device inserted into the plug part 31 .

[0058] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the third connection portion 3 has a first connection surface 33, and the first connection surface 33 is arranged on the axial end surface of the discharge connection device 100. The plug-in portion 31 can be arranged on the first connection surface 33, so that the plug-in portion 31 is located on the axial end surface of the discharge connection device 100, so that the plug-in process of the plug 300 and the plug-in portion 31 is smoother and more convenient.

[0059] Furthermore, when the first connection part 200 is in a connected state with the second connection part 2, the first connection surface 33 is a vertical surface, which can prevent the plug 300 from being subjected to a vertical downward force when the plug 300 is inserted into the first connection surface 33, and can prevent the plug-in part 31 from being disconnected under load, thereby increasing the reliability of the connection between the plug-in part 31 and the plug 300.

[0060] Alternatively, along the axial direction of the discharge connection device 100, the first connection surface 33 is inclined upward at an angle A, and 0<A≤10° is satisfied. It can be understood that the angle A of the first connection surface 33 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 of the first connection surface 33 is not less than 0°, which can prevent the plug 300 from being subjected to a vertical downward force when the plug 300 is inserted into the plug part 31, and can prevent the plug part 31 from being disconnected under load, thereby increasing the reliability of the connection between the plug part 31 and the plug 300; the angle A of the first connection surface 33 is not greater than 10°, which can prevent the first connection surface 33 from being inclined too much upward, and can make the process of inserting the plug 300 into the plug part 31 more convenient.

[0061] In some embodiments of the present invention, Figure 4 As shown, the second connection part 2 has a second connection surface 21, and the first connection surface 33 is provided on the axial end surface of the discharge connection device 100, and the normal line of the first connection surface 33 is parallel to the normal line of the second connection surface 21. The first connection surface 33 and the second connection surface 21 of the discharge connection device 100 are parallel, and the first connection part 200 and the second connection part 2 are parallel. The discharge connection device 100 has a simple structure, a small volume, a small space occupation, and is easy to use. When the first connection part 200 and the second connection surface 21 are matched, the second connection surface 21 and the first connection part 200 are matched more conveniently.

[0062] In addition, the second connection part 2 of the discharge connection device 100 and the first connection part 200 of the vehicle can be connected before or after the plug 300 and the plug-in part 31 are plugged in, which can ensure that the interface between the plug 300 and the first connection part 200 is horizontally stressed, and the port of the first connection part 200 is not stressed, so that the discharge connection device 100 is durable and reliable.

[0063] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the third connecting portion 3 is provided with a second switch 34 , and the second switch 34 is triggered when the plug 300 is plugged into the plug-in portion 31 , and the second switch 34 is connected in series with the first switch 32 .

[0064] It is understandable that if Fig.10 As shown, CC and PE are two ends of the circuit connected to the vehicle and the discharge connection device 100, and the connection between the discharge connection device 100 and the vehicle has the following five states:

[0065] State 1: When the discharge connection device 100 and the first connection part 200 of the vehicle are connected, and the plug 300 of the electrical device in the third connection part 3 is not inserted into the plug-in part 31, the vehicle detects that the resistance between CC and PE is R4'+RC', and the vehicle displays that there is a plug-in signal at the first connection part 200 of the vehicle, but does not start discharging;

[0066] State 2: When the discharge connection device 100 and the first connection part 200 of the vehicle are connected, and only the plug 300 of the electric device in the third connection part 3 is inserted into the plug-in part 31, the plug 300 of the electric device closes one of the switches S1' or S2', and the vehicle detects that the resistance between CC and PE is R4'+RC', and the vehicle displays that there is a plug-in signal at the first connection part 200 of the vehicle, but does not start discharging;

[0067] State 3: the discharge connection device 100 and the first connection part 200 of the vehicle, when the plug 300 of the electrical device in the third connection part 3 is inserted into the plug-in part 31, the protective cover 4 is closed, and the protective cover 4 closes the remaining switch S1' or S2'. The vehicle detects that the resistance between CC and PE is RC', and the vehicle displays a signal that the discharge connection device 100 and the plug 300 are fully connected, and the discharge is started;

[0068] State 4: When the power is finished, the user opens the protective cover 4, and the protective cover 4 opens one of the switches S1' or S2'. The vehicle detects that the resistance between CC and PE is R4'+RC', and the discharge is finished. The user then unplugs the plug 300 of the electrical device, and the plug-in part 31 of the discharge connection device 100 will not be disconnected under load, thereby increasing the service life of the plug-in part 31;

[0069] State 5: When power consumption ends, the user presses S3 first, and the vehicle detects that the resistance between CC and PE is R4'+RC', ending discharge. The switch structure is consistent with the AC or DC charging gun described in the IEC 62196 and GB / T 20234 series standards, but when used for the discharge connection device 100, the S3 switch can be installed selectively.

[0070] The second connection part 2 of the discharge connection device 100 and the first connection part 200 of the vehicle include standard interfaces in accordance with the national, European and American standards defined in the IEC 62196 and GB / T 20234 series of standards. The type of the plug part 31 on the third connection part 3 of the discharge connection device 100 should include a socket type in accordance with the IEC TR 60083 and GB / T 1002 series of standards.

[0071] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, the protective cover 4 is provided with a wire outlet groove 42, which is used for the wire harness 400 connected to the plug 300 to pass through the protective cover 4, so that the wire harness 400 has a more reliable outlet position after the plug 300 of the electrical device is connected to the plug-in portion 31, thereby increasing the reliability of the plug 300 of the electrical device.

[0072] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the protective cover 4 covers the plug-in portion 31 and when the first connection portion 200 and the second connection portion 2 are connected, one end of the wire outlet groove 42 in the length direction is located on the surface of the protective cover 4 opposite to the plug-in portion 31, and the other end extends downward to the opening of the protective cover 4. This prevents rainwater from contacting the plug-in portion 31 when the wire harness 400 is connected to the tail of the plug 300 or the wire harness 400 is vertically downward relative to the plug-in direction of the plug 300, and the wire harness 400 can pass through the wire outlet groove 42 when the wire harness 400 is connected to the tail of the plug 300 or the wire harness 400 is vertically downward relative to the plug-in direction of the plug 300, and the discharge connection device 100 has a wider application range.

[0073] In some embodiments of the utility model, a first magnetic member is provided on the protective cover 4, a second magnetic member cooperating with the first magnetic member is provided on the third connecting portion 3, and the first magnetic member is magnetically connected to the second magnetic member. Among them, one of the first magnetic member and the second magnetic member is a magnet, and the other of the first magnetic member and the second magnetic member is a magnet or metal, and the magnets in the first magnetic member and the second magnetic member can also be electromagnets, and the first magnetic member and the second magnetic member can attract each other to provide a certain holding force.

[0074] A fixing structure is also provided on the protective cover 4, and the first magnetic component is provided on the fixing structure of the protective cover 4, which can reduce the distance between the first magnetic component and the second magnetic component, and the cooperation between the first magnetic component and the second magnetic component is more convenient.

[0075] In addition, the holding force between the first magnetic member and the second magnetic member can increase the matching relationship between the first switch 32 and the trigger structure 41 on the protective cover 4, thereby increasing the reliability of the matching between the protective cover 4 and the first switch 32.

[0076] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, the third connection part 3 is provided with a first sealing ring 35, and the first sealing ring 35 surrounds the plug-in part 31. When the protective cover 4 covers the plug-in part 31, the protective cover 4 and the third connection part 3 are sealed and connected through the first sealing ring 35. The connection between the protective cover 4 and the third connection part 3 can be made more reliable, and the protective cover 4 and the third connection part 3 are sealed, and the sealing effect of the protective cover 4 and the third connection part 3 is better. In addition, the holding force between the first magnetic attraction member and the second magnetic attraction member can increase the reliability of the sealed connection between the protective cover 4 and the third connection part 3.
