[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to the attached document. Figures 1-5 This application provides an embodiment of a quick-connect charging and discharging box 100, which is used to electrically connect a high-voltage cabinet to an energy storage battery system.

[0036] Please refer to the attached document. Figures 1-5 In this embodiment, the quick-connect charging and discharging box 100 includes a box body 10, a busbar assembly 20, a plug 30, and a connecting assembly 40. A power distribution cavity 10a is formed inside the box body 10, and the box body 10 has a first inlet hole 10b and a second inlet hole 10c, respectively communicating with the power distribution cavity 10a. The first inlet hole 10b is used for the energy storage wires of the energy storage battery system to pass through. The busbar assembly 20 is disposed in the power distribution cavity 10a and is insulated from the box body 10. The plug 30 passes through the second inlet hole 10c and is insulated from the box body 10. The plug 30 is used for plugging into the high-voltage wires of the high-voltage switchgear. The connecting assembly 40 is disposed in the power distribution cavity 10a and is electrically connected to both the plug 30 and the busbar assembly 20. This allows the plug 30 to be electrically connected to the busbar assembly 20 via the connecting assembly 40, and the high-voltage wires of the high-voltage switchgear are connected to the plug 30 via a quick-connect method. This facilitates the electrical connection of the high-voltage cable of the high-voltage switchgear to the busbar assembly 20 via the plug 30, avoiding the need for bolts to press the high-voltage cable of the high-voltage switchgear to the busbar assembly 20. This prevents excessive temperature rise caused by loose bolts between the high-voltage cable and the busbar assembly 20, improves the ease of connection of the high-voltage cable of the high-voltage switchgear, and enhances work efficiency.

[0037] Please refer to the attached document. Figures 1-2In this embodiment, the housing 10 serves as a support component of the quick-connect charging and discharging box 100, supporting the busbar assembly 20, the plug 30, and the connection assembly 40. A power distribution cavity 10a is formed inside the housing 10, serving as the internal space of the housing 10. The housing 10 has a first inlet hole 10b and a second inlet hole 10c, respectively communicating with the power distribution cavity 10a. The first inlet hole 10b and the second inlet hole 10c are located at different positions within the housing 10. The first inlet hole 10b is used for the energy storage wires of the energy storage battery system to pass through; this allows the energy storage wires of the energy storage battery system to enter the power distribution cavity 10a through the first inlet hole 10b, thereby ensuring that one end of the energy storage wire is inside the housing 10 and the other end is outside the housing 10.

[0038] Please refer to the attached document. Figures 1-2 5. In this embodiment, the busbar assembly 20 is disposed in the distribution cavity 10a and insulated from the housing 10; this allows the busbar assembly 20 to be fixed inside the housing 10, facilitating the connection of one end of the energy storage cable of the energy storage battery system located inside the housing 10 to the busbar assembly 20. The insulation between the busbar assembly 20 and the housing 10 prevents the housing 10 from becoming energized, thus preventing electric shock when a user touches the housing 10 and improving the safety of the housing 10.

[0039] Please refer to the attached document. Figures 1-4 In this embodiment, the plug 30 is arranged relative to the second inlet hole 10c. The plug 30 passes through the second inlet hole 10c and is insulated from the housing 10, so that the plug 30 can be connected to the housing 10 through the second inlet hole 10c. This allows one end of the plug 30 to be exposed to the external environment, while the other end of the plug 30 is located inside the power distribution cavity 10a. The insulation between the plug 30 and the housing 10 prevents the housing 10 from becoming live, thus preventing electric shock when the user touches the housing 10 and improving the safety of the housing 10.

[0040] Please refer to the attached document. Figure 2 In this embodiment, the plug 30 is used to connect to the high-voltage wires of the high-voltage switchgear. The connecting assembly 40 is disposed in the distribution cavity 10a and is electrically connected to both the plug 30 and the busbar assembly 20, facilitating the electrical connection between the plug 30 and the busbar assembly 20 via the connecting assembly 40. The high-voltage wires of the high-voltage switchgear are connected to the plug 30 via a quick-connect method, thus facilitating the electrical connection between the high-voltage wires and the busbar assembly 20. This avoids the need for bolts to press the high-voltage wires into the busbar assembly 20, improving the ease of connection and work efficiency. It also prevents excessive temperature rise between the high-voltage wires and the busbar assembly 20 due to loose bolts.

[0041] Please refer to the attached document. Figure 2The busbar assembly 20 extends along the height of the enclosure 10, with multiple plugs 30 and multiple connecting assemblies 40. The plugs 30 are spaced apart along the height of the enclosure 10. Each connecting assembly 40 connects to one plug 30, allowing each plug 30 to be electrically connected to the busbar assembly 20 via its respective connecting assembly 40. By arranging multiple plugs 30, multiple high-voltage cabinets can be connected to multiple plugs 30, enabling simultaneous connection of multiple different high-voltage cabinets. Alternatively, different plugs 30 can output different currents to adapt to various high-voltage cabinets, improving the versatility of the quick-connect charging and discharging box 100. Two plugs 30 are arranged side-by-side as a group, with one group consisting of an AC power socket and a DC cable socket, allowing the positive and negative terminals of the high-voltage wires of the high-voltage cabinet to be connected to the AC power socket and the DC cable socket, respectively.

[0042] Please refer to the attached document. Figures 1-2 The housing 10 includes an end plate 11, a first side plate 12, and a second side plate 13. The end plate 11 is located at opposite ends in the height direction of the housing 10, which is the vertical direction. The first side plate 12 is located at opposite ends in the length direction of the housing 10, which is the horizontal direction. The second side plate 13 is located at opposite ends in the width direction of the housing 10, which is the front-to-back direction. A first inlet hole 10b is provided on the end plate 11 to allow the energy storage wires of the energy storage battery system to enter the housing 10 from top to bottom or from bottom to top through the first inlet hole 10b. A second inlet hole 10c is provided on the first side plate 12. A plug 30 passes through the second inlet hole 10c from left to right into the housing 10. The plug 30 is arranged along the length direction of the housing 10 for easy wiring. The busbar assembly 20 is insulated from the second side plate 13. This insulation prevents the second side plate 13 from becoming live, thus preventing electric shock when the user touches it and improving its safety. The width of the first side plate 12 is smaller than the width of the second side plate 13. The connecting components 40 are arranged along the width of the second side plate 13 to facilitate better arrangement of multiple connecting components 40 relative to the second side plate 13, while also reducing the material cost of the enclosure 10. The end plate 11, the first side plate 12, and the second side plate 13 enclose a power distribution cavity 10a to accommodate the busbar assembly 20, some plugs 30, and connecting components 40.

[0043] Please refer to the attached document. Figures 2-5The connecting assembly 40 includes multiple fastening screws 41, multiple fastening nuts 42, and a connecting plate 43. The two opposite ends of the connecting plate 43 are electrically connected to the busbar assembly 20 and the plug 30, respectively. One of the multiple fastening screws 41 passes through the connecting plate 43 and the plug 30 and is fixedly connected to the fastening nut 42, so that the fastening screw 41 and the fastening nut 42 can cooperate to clamp the connecting plate 43 and the plug 30, ensuring the connection stability between the connecting plate 43 and the plug 30. At the same time, the connecting plate 43 and the plug 30 are detachably connected by a fastening screw 41 and a fastening nut 42, which facilitates the disassembly and assembly of the connecting plate 43 and the plug 30. One of the multiple fastening screws 41 passes through the connecting plate 43 and the busbar assembly 20 and is fixedly connected to the fastening nut 42, so that the fastening screw 41 and the fastening nut 42 can cooperate to clamp the connecting plate 43 and the busbar assembly 20, ensuring the connection stability between the connecting plate 43 and the busbar assembly 20. At the same time, the connecting plate 43 and the busbar assembly 20 are detachably connected by the fastening screw 41 and the fastening nut 42, which facilitates the disassembly and assembly of the connecting plate 43 and the busbar assembly 20.

[0044] Please refer to the attached document. Figures 3-4 The outer periphery of the plug 30 is provided with a skirt 31, which overlaps the surface of the housing 10 so as to block the gap between the plug 30 and the second inlet hole 10c, preventing external dust from entering the housing 10 through the gap between the plug 30 and the second inlet hole 10c, thereby achieving a dustproof effect.

[0045] Please refer to the attached document. Figures 3-4 The quick-connect charging and discharging box 100 also includes a sealing gasket 50, which is sandwiched between the skirt 31 and the box body 10. This allows the skirt 31 to be sealed relative to the box body 10 through the sealing gasket 50, ensuring a sealing effect at the connection between the skirt 31 and the box body 10. This prevents external water from entering the box body 10 through the connection between the plug 30 and the box body 10, further achieving waterproof and dustproof effects.

[0046] The housing 10 has a receiving groove 10d, and the sealing gasket 50 is assembled in the receiving groove 10d so that the sealing gasket 50 can be engaged with the housing 10 through the receiving groove 10d, ensuring the connection stability between the sealing gasket 50 and the housing 10. The skirt 31 has multiple spaced limiting grooves 31a on the side facing the sealing gasket 50. Part of the sealing gasket 50 is received in the limiting grooves 31a. By arranging multiple spaced limiting grooves 31a, the sealing area between the sealing gasket 50 and the skirt 31 and the housing 10 is increased. When the sealing gasket 50 in one limiting groove 31a fails, the sealing gasket 50 in another limiting groove 31a remains sealed, ensuring the sealing effect between the sealing gasket 50 and the skirt 31 and the housing 10.

[0047] Please refer to the attached document. Figure 5The bus assembly 20 includes multiple insulating posts 21 and a busbar 22. The insulating posts 21 are spaced apart on the housing 10, with their opposite ends connected to the busbar 22 and the housing 10, respectively. This spacing between the busbar 22 and the housing 10 ensures the busbar 22 remains flat relative to the housing 10, preventing the housing 10 from becoming energized and guaranteeing its safety. The multiple insulating posts 21 ensure the busbar 22 is level with respect to the housing 10. The busbar 22 is electrically connected to the connecting component 40, allowing the busbar assembly 20 to conduct electricity with the connecting component 40 via the busbar 22. Optionally, the busbar 22 is a copper busbar. There are two busbars 22, one for the positive terminal and one for the negative terminal.

[0048] Please refer to the attached document. Figure 5 The bus assembly 20 also includes an isolation plate 23, which is disposed between the insulating post 21 and the bus 22. In the thickness direction of the isolation plate 23, the projection of the bus 22 falls on the isolation plate 23, thereby increasing the distance between the bus 22 and the housing 10. This increases the creepage distance, preventing insufficient spacing between the bus 22 and the housing 10 and avoiding electrical conduction between the bus 22 and the housing 10.

[0049] In another embodiment, a power distribution system includes an energy storage battery system, a high-voltage switchgear, and a quick-connect charging / discharging box 100. The energy storage battery system is electrically connected to the busbar assembly 20 of the quick-connect charging / discharging box 100 via energy storage cables, enabling electrical conductivity between the energy storage battery system and the quick-connect charging / discharging box 100. The high-voltage cables of the high-voltage switchgear are plugged into the plug 30 of the quick-connect charging / discharging box 100 via a quick-connect method, avoiding the need for bolts to press the high-voltage cables of the high-voltage switchgear into the quick-connect charging / discharging box 100. This allows the energy storage battery system to conduct electricity with the high-voltage switchgear through the quick-connect charging / discharging box 100.

[0050] The beneficial effects of this invention are as follows:

[0051] This utility model provides a quick-connect charging and discharging box 100. The box body 10 has a power distribution cavity 10a inside. The box body 10 has a first inlet hole 10b and a second inlet hole 10c, respectively communicating with the power distribution cavity 10a. The first inlet hole 10b is used for the energy storage wires of the energy storage battery system to pass through. A busbar assembly 20 is disposed in the power distribution cavity 10a and insulated from the box body 10. A plug 30 passes through the second inlet hole 10c and is insulated from the box body 10. The plug 30 is used for plugging into the high-voltage wires of the high-voltage switchgear. A connecting assembly 40 is disposed in the power distribution cavity 10a and is divided into... Do not electrically connect the plug 30 and busbar assembly 20, so that the plug 30 can be electrically connected to the busbar assembly 20 through the connecting component 40. The high-voltage wires of the high-voltage switchgear are connected to the plug 30 by a quick-connect method, which facilitates the electrical connection of the high-voltage wires of the high-voltage switchgear to the busbar assembly 20 through the plug 30. This avoids the high-voltage wires of the high-voltage switchgear being crimped to the busbar assembly 20 with bolts, and prevents excessive temperature rise caused by loose bolts between the high-voltage wires of the high-voltage switchgear and the busbar assembly 20. This improves the convenience of connecting the high-voltage wires of the high-voltage switchgear and improves work efficiency.
