[0088] A preferred embodiment is given below and combined with the accompanying drawings to more clearly and completely illustrate the present invention.

[0089] like Figure 1-7 As shown, this embodiment provides a modular charging cabinet 100. The modular charging cabinet 100 includes:

[0090] A cabinet body, wherein a plurality of charging compartments 1 are provided inside the cabinet body;

[0091] A plurality of chargers 2, wherein the chargers 2 are installed in the charging compartment 1;

[0092] The cabinet has a main air duct 3 and a circuit channel 4 inside. The cabinet has an air outlet 31 on the top. The air outlet 31 is connected to the main air duct 3 , the charger 2 is connected to the main air duct 3 , and the charger 2 is connected to the circuit channel 4 .

[0093] The modular charging cabinet 100 in this embodiment provides a modular and pre-installed modular charging cabinet 100 as a whole through the above-mentioned structural arrangement. A charging compartment for installing a charger is reserved in the cabinet of the modular charging cabinet and the main air duct is integrated. During on-site construction, the charger can be directly loaded into the charging compartment to complete the on-site assembly. The modular charging cabinet as a whole does not need to be installed on-site, which is convenient for transportation and use.

[0094] In this embodiment, a charging compartment 1 is disposed on a first side of the modular charging cabinet 100, and a circuit channel 4 and a main air duct 3 are disposed in parallel on a second side of the modular charging cabinet 100. Specifically, the first side and the second side may be, but are not limited to, opposite sides.

[0095] In this embodiment, the charging compartment 1 is extended horizontally and stacked from bottom to top in the vertical direction. The main air duct 3 and the circuit channel 4 both extend upward from the bottom of the modular charging cabinet 100. In this way, the charging compartment 1, the circuit channel 4 and the main air duct 3 are respectively arranged in the internal space on both sides of the modular charging cabinet 100, avoiding the front area. In other words, when other structures are arranged in the face of the charging rack to cooperate with the modular charging cabinet 100, they will not be affected by the internal structure of the modular charging cabinet 100.

[0096] Specifically, the charging compartment 1 is divided into seven layers, each of which is used to accommodate a maximum of seven chargers 2 .

[0097] like Figure 1-7 As shown, in this embodiment, the modular charging cabinet 100 is closed on one side of the main air duct 3 and the circuit channel 4 .

[0098] Specifically, the modular charging cabinet 100 in this embodiment includes a frame 62 and an outer panel 61, and the outer panel 61 is mounted on the frame 62. Since the overall structure of the modular charging cabinet 100 is mainly composed of the frame 62 and the outer panel 61, it is convenient to perform overall modularization operations, and the overall structure composed of the frame 62 and the outer panel 61 is conducive to improving the waterproof and dustproof performance of the modular charging cabinet 100, and preventing other objects from entering the main air duct 3 and the circuit channel 4.

[0099] Furthermore, on one side of the main air duct 3 and the circuit channel 4, the interior of the modular charging cabinet 100 is closed by an outer panel 61 installed on the frame 62. By closing the modular charging cabinet on one side of the main air duct 3 and the circuit channel 4 with the outer panel, the sealing performance of the main air duct 3 can be ensured, and the strong electrical components in the circuit channel 4 can be isolated to ensure safe use.

[0100] In this embodiment, the closure here does not specifically refer to a completely isolated seal, but rather a gap space without an open portion or affecting the overall closure of the structure. It should be noted by those skilled in the art that the basic structure composed of the frame 62 and the outer plate 61 already has a certain waterproof and dustproof effect. Of course, those skilled in the art can also add some sealing components on one side of the main air duct 3 and the circuit channel 4 according to the actual situation of the installation location to achieve a better waterproof and dustproof effect.

[0101] like Figure 1-7 As shown, in this embodiment, an opening is provided on the modular charging cabinet 100, and the opening is connected to the charging compartment 1, and the charger 2 is inserted into or removed from the charging compartment 1 from the opening. Specifically, the charger 2 is inserted into the charging compartment 1 from the opening and is stored in the charging compartment 1. In this embodiment, the size and shape of the interior of the charging compartment 1 are substantially the same as those of the charger 2. When the charger 2 and the modular charging cabinet 100 are disassembled and assembled, the charger 2 can be inserted into or removed from the charging compartment 1 from the opening, which is more convenient to operate.

[0102] like Figure 1-7 As shown, in this embodiment, the charger 2 has a cooling air duct 21 inside, and the cooling air duct 21 is arranged along the direction in which the charger 2 is inserted into the charging compartment 1. The inlet of the cooling air duct 21 is connected to the outside, and the outlet of the cooling air duct 21 is connected to the main air duct 3. Furthermore, the main air duct 3 has a plurality of air inlets 32, each of which corresponds to the charging compartment 1 one by one, and the air inlet 32 ​​is connected to and connected with the outlet of the corresponding cooling air duct 21.

[0103] Specifically, in this embodiment, air flow is sucked into the cooling air duct 21 of the charger 2 from the outside, and is exhausted to the main air duct 3 through the air inlet 32 ​​of the main air duct 3, and then discharged upward from the main air duct 3 to the outside of the modular charging cabinet 100.

[0104] In this embodiment, when the charger 2 is installed, the cooling air duct 21 in the charger 2 and the main air duct 3 are connected through the air inlet 32, depending on the positional relationship between the charger 2 and the air inlet 32. That is, as the charger 2 is installed in place, the cooling air duct 21 and the main air duct 3 can be automatically connected.

[0105] like Figure 1-7 As shown, in this embodiment, the modular charging cabinet 100 further includes a sealing plate, which is detachably connected to the main air duct 3 at the air inlet 32 ​​.

[0106] Specifically, when all chargers 2 are installed, all sealing plates are removed, and the corresponding positions are occupied by chargers 2. When no charger 2 is installed in a charging compartment 1 or the charger 2 is removed, the sealing plate can be installed at the corresponding air inlet 32, and the sealing performance of the main air duct 3 can be maintained by using the sealing plate installed on the air inlet 32.

[0107] like Figure 1-7 As shown, in this embodiment, a busbar 41 and a wire are provided in the circuit channel 4, and the busbar 41 is connected to a power source 5 outside the cabinet through the wire.

[0108] In this embodiment, the circuit is integrated into the circuit channel 4, and the busbar and the power supply are directly connected by wires. There is no need to set up wiring terminals, and there is no need to reinstall the circuit part of the modular charging cabinet 100, which makes the modular charging cabinet 100 more convenient to install and helps save costs.

[0109] Furthermore, in this embodiment, the busbar 41 is installed on one side of the circuit channel 4 close to the charging compartment 1, and an electrical connector is installed on the outside of the circuit channel 4. The electrical connector corresponds one-to-one to the charging compartment 1, and the busbar 41 is connected to the charger 2 through the electrical connector.

[0110] Similar to the principle of the main air duct 3, in this embodiment, the positional relationship between the electrical connector and the charging compartment 1 enables the charger 2 to automatically dock with the electrical connector after being inserted into the charging compartment 1 to achieve electrical connection, and is connected to the power source 5 through circuit parts such as the busbar 41. Specifically, the electrical connector and the busbar 41 are connected through a wire.

[0111] In the existing charging rack, the charger 2 is usually connected to the electrical connector using wires and terminals alone after the charger 2 is installed and fixed. In this embodiment, the electrical connector is pre-connected to the busbar 41 by wires, and no additional installation steps are required. At the same time, the overall structure is not limited by size when setting up, and the space arrangement between the charging compartment 1 and the busbar 41 can be realized.

[0112] Specifically, after the charger 2 is installed, a circuit is formed from the power source 5 to the busbar 41, then to the electrical connector and finally connected to the charger 2. For ease of description, the electrical connector connected to the busbar 41 in this embodiment is referred to as the busbar electrical connector 42.

[0113] In this embodiment, a plug-in guide surface is provided on the plug-in end of the electrical connector and / or the charger 2 .

[0114] Specifically, in this embodiment, the plug-in guide surface is used to directly connect the charger 2 and the busbar electrical connector 42, and the plug-in guide surface is automatically connected when the charger 2 is installed in place. The plug-in guide surface in this embodiment is two mutually matching inclined surfaces. In other embodiments, the plug-in guide surface can also be mutually matching conical surfaces or other matching surfaces with a guiding function.

[0115] In this embodiment, the inner and / or outer surfaces of the circuit channel 4 have an insulating layer. Specifically, the insulating layer is made of rubber material.

[0116] Since the circuit channel 4 is a high-current part, it is extremely dangerous if it leaks, so an additional insulating layer is provided to prevent the high-current part in the circuit channel 4 from leaking and causing danger.

[0117] It should be understood that the circuit channel 4 in this embodiment is formed in the internal space of the modular charging cabinet 100, so the inner and / or outer surfaces of the circuit channel 4 correspond to the inner and / or outer surfaces of the outer plate 61 of the modular charging cabinet 100. However, in other embodiments, the circuit channel 4 can be a physical channel located in the internal space of the modular charging cabinet 100. In this case, the physical channel should also be provided with an insulating layer to ensure safety.

[0118] Of course, no matter in which implementation mode, the staff will still directly contact the outer panel 61 of the modular charging cabinet 100 under normal circumstances, so the internal setting does not affect the need to set an insulating layer on the inner and / or outer surface of the outer panel 61 of the modular charging cabinet 100.

[0119] like Figure 1-7 As shown, in this embodiment, one side of the cabinet is provided with a cylinder channel 7, and the cylinder channel 7 is connected to the charging compartment 1.

[0120] Since the charging compartment 1 in this embodiment contains the charger 2, and the charger 2 is ejected or retracted by the cylinder on the battery rack at the joint with the battery pack to be charged, a cylinder channel 7 is provided inside the modular charger cabinet 100. The cylinder channel 7 is used to provide space in the stroke direction of the cylinder to correspond to the ejection or retraction of the cylinder during its stroke.

[0121] Specifically, another electrical connector is installed at the movable end of the cylinder, which is called a charging electrical connector in this embodiment and is used to connect to the battery pack to be charged.

[0122] Furthermore, when charging is required, the charger 2 is started, the cylinder pushes out the charging electrical connector, and plugs it into the battery pack to be charged. When charging is completed, the cylinder retracts the charging electrical connector, unplugs it, and retracts it into the cylinder channel 7.

[0123] like Figure 1-7 As shown, in this embodiment, the top of the modular charging cabinet 100 also has a plurality of lifting ears 63. Specifically, the number of the lifting ears 63 is four, which are respectively arranged at the four corners of the top surface of the modular charging cabinet 100. After the overall pre-installation is completed, the lifting equipment can be used in conjunction with the lifting ears 63 to realize the lifting, transportation and installation of the modular charging cabinet 100 as a whole. And the four lifting ears 63 are respectively arranged at the four corners of the top surface of the modular charging cabinet 100 so that the modular charging cabinet 100 is evenly stressed during the lifting process, and the lifting and transportation is stable and reliable.

[0124] The modular charging cabinet 100 in this embodiment also includes a duct floating joint 8. The duct floating joint 8 is connected to the cabinet at the air outlet 31, and the duct floating joint 8 is used to connect the main air duct 3 and the hot air duct 9 outside the modular charging cabinet 100. The duct floating joint 8 includes a flexible pipe 81 and a push component. The flexible pipe 81 is connected to the main air duct 3, and the push component is connected to the flexible pipe 81 and applies a force to the flexible pipe 81 toward the hot air duct 9 to achieve communication between the flexible pipe 81 and the hot air duct 9.

[0125] Since the air duct in the prior art is usually composed of air pipes, the connection between the air ducts must meet the basic structural requirements of stability and firmness while meeting the air duct performance requirements. In the prior art, fixings and / or seals are usually used to achieve this, which is not conducive to on-site installation and removal, and it is also necessary to add additional structures to increase the overall weight of the air duct. In the present embodiment, the flexible pipe 81 of the air duct floating joint 8 is a part of the overall air duct structure. Under the action of the pushing component, it is close to the hot air duct 9 to form a connection structure of the main air duct 3-flexible pipe 81-hot air duct 9. During installation, the first end of the air duct floating joint 8 is first installed on one side of the main air duct 3, and then the main air duct 3 and the hot air duct 9 are aligned and brought close to each other, so that the pushing component can make the second end of the flexible pipe 81 close to the hot air duct 9.

[0126] In this embodiment, the main air duct 3 and the hot air duct 9 are connected by the air duct floating joint 8 without the need for other connecting components. The pushing component applies force to the flexible pipe 81 so that the flexible pipe 81 can be closely attached to the hot air duct 9 to form a connecting structure, ensuring that the main air duct 3 and the second hot air duct 9 are connected stably and reliably. The air duct floating joint 8 can effectively improve the installation efficiency of the air duct connection structure.

[0127] The flexible pipe 81 in this embodiment includes a flexible pipe 81 body and a base plate 82. One end of the base plate 82 is connected to one end of the flexible pipe 81 body close to the hot air duct 9 and extends outward, and the base plate 82 is connected to the push component.

[0128] In this embodiment, the upper end of the flexible pipe 81 has a base plate 82, and the push component directly acts on the base plate 82 to drive the body of the flexible pipe 81 to move. In order to make the stress state of the end of the flexible pipe 81 close to the hot air duct 9 more stable, a base plate 82 extending laterally outward is provided at the upper end of the flexible pipe 81.

[0129] Specifically, the cross-sectional shapes of the main air duct 3, the hot air duct 9 and the flexible pipe 81 in this embodiment are all rectangular. Therefore, for the consideration of force stability, the outer contour of the base plate 82 is also set to be rectangular. Of course, in some other special structural forms, it is not required that the outer contour of the base plate 82 is the same as the cross-sectional shape of the flexible pipe 81.

[0130] like Figure 1-7 As shown, the air duct floating joint 8 in this embodiment also includes a guide mechanism. The guide mechanism is used to guide the base plate 82 to move in a direction close to the hot air duct 9. The flexible duct 81 also includes a mounting plate, and the flexible duct body, the push component and the guide mechanism are all mounted on the mounting plate.

[0131] In this embodiment, the air duct floating joint 8 includes a mounting plate, and the air duct floating joint 8 is connected to the main air duct 3 through the mounting plate. When the air duct floating joint 8 is connected to the main air duct 3, the mounting plate can be directly connected to the main air duct 3, and the connection operation is simple and convenient. However, it should be noted that in other embodiments, the flexible pipe 81 body, the push component and the guide mechanism of the air duct floating joint 8 can also be directly installed on the main air duct 3. The air duct floating joint 8 with this structure is conducive to cost saving.

[0132] Compared with direct installation, in this embodiment, when installing the air duct floating joint 8, the corresponding structure can be installed on the mounting plate in advance, and finally the mounting plate can be fixed on the main air duct 3 to complete the installation, which is more suitable for modular overall operation.

[0133] For the convenience of description, the present embodiment is described by taking as an example that the air duct floating joint 8 includes a mounting plate, and the air duct floating joint 8 is connected to the main air duct 3 as a whole through the mounting plate.

[0134] Specifically, in this embodiment, the guide mechanism is a guide post 84. The guide post 84 is connected to the mounting plate, and the base plate 82 is provided with a guide hole 85, and the guide post 84 is passed through the guide hole 85.

[0135] In this embodiment, the guide post 84 is fixed to the mounting plate and passes through the guide hole 85 on the base plate 82. That is, when the guide post 84 does not separate from the guide hole 85, the base plate 82 is guided by the guide post 84 to move along the center line direction of the flexible pipe 81, and is also restricted by the guide post 84 to prevent its position in the horizontal plane from changing, thereby avoiding interference in the structure and increasing the stability of the structure.

[0136] Furthermore, if Figure 1-7 As shown, the push component in this embodiment is a spring 83. The two ends of the spring 83 are respectively against the mounting plate and the base plate 82. There are multiple springs 83, and the multiple springs 83 are respectively arranged on the outer edges of the four sides of the base plate 82, which can provide a more uniform push force. Specifically, the four springs 83 in this embodiment are respectively arranged at the four corners of the base plate 82.

[0137] In this embodiment, the spring 83 is sleeved on the guide column 84, that is, the guide column 84 is inserted into the spring 83. In this way, the spring 83 can also be guided by the guide structure, and during the guiding process, the spring 83 always moves along the outer surface of the guide column 84. In this way, the spring 83 can be prevented from being damaged by lateral deformation, thereby improving the structural stability of the overall air duct floating joint 8.

[0138] The push component is a key component for providing the push force and is a key component for the floating joint 8 of the air duct to achieve docking. During the installation process, the guide column 84 and the guide hole 85 on the base plate 82 are used to limit the direction of movement, and the push component further provides a uniform and stable push force under the premise of structural stability. Therefore, in this embodiment, a spring 83 is used as a push component, and the spring 83 is arranged at the four corners of the base plate 82 to obtain a more uniform push force. Of course, under the premise of ensuring balance, those skilled in the art can refer to the actual effect and appropriately increase the number of springs 83 or change their arrangement rules to adapt to different air duct structures or shapes.

[0139] Furthermore, the air duct floating joint 8 also includes a sealing member 86, which is connected to the base plate 82, and the sealing member 86 is configured to fit against the hot air duct 9. When the air duct floating joint 8 realizes the connection between the main air duct 3 and the hot air duct 9, the inside of the air duct floating joint 8 should have good sealing performance. Based on this, the sealing member 86 is arranged on the base plate 82, and when the pushing component pushes the base plate 82 toward the hot air duct 9, the sealing member 86 abuts against the second sealing channel, and the sealing is automatically achieved with the help of the thrust, so that the air duct formed after the hot air duct 9 and the flexible pipe fit together has better air tightness.

[0140] Furthermore, the material of the seal 86 is heat-resistant rubber. In this embodiment, the integral air duct is used as a heat dissipation structure, and the air flow temperature therein is sometimes high. In order to prevent the rubber from losing elasticity and hardness due to heat, heat-resistant rubber is used as the material of the seal 86, which not only ensures the mechanical properties of the seal 86, but also improves the heat resistance of the seal 86.

[0141] Similarly, in this embodiment, the flexible pipe body is made of fireproof silicone cloth. Similar to the sealing member 86, the flexible pipe also needs to have a certain heat resistance, so the flexible pipe made of fireproof silicone cloth is used in this embodiment.

[0142] In other embodiments of the present invention, the pushing component includes a bolt and a nut, the bolt is connected to the mounting plate, the nut is connected to the base plate 82, and the bolt and the nut are connected by threads.

[0143] In this embodiment, the push component adopts a bolt-nut structure, and the push force can be adjusted by adjusting the position of the nut on the bolt, and then the base plate 82 is tightened by the bolt to apply a force toward the hot air duct 9 to the flexible pipe, so that the flexible pipe is closely attached to the hot air duct 9. In addition, in this embodiment, the push force acts directly on the base plate 82, and its connection structure and force transmission effect are more stable and reliable.

[0144] Furthermore, the push component further includes a spring 83, which is sleeved on the bolt. The provision of the spring 83 helps to increase the push force, further ensuring that the push is stable and reliable. In addition, the bolt is inserted into the spring 83, so that the spring 83 is also guided by the bolt, and its function is as described above, which will not be repeated here.

[0145] The difference between the above-mentioned different embodiments is only the different structures of the pushing components, and the other components and structural components are the same, which will not be described in detail here.
