[0002] Technical Field

[0003] The present application relates to the technical field of power distribution control equipment, and in particular to a low-voltage control distribution box.

[0004] Background Art

[0005] The control box of the battery system of an electric ship adopts a combiner cabinet model, but the traditional combiner cabinet design cannot meet the needs of current ship power distribution system design.

[0006] Technical issues

[0007] The control box for the battery system of an electric vessel uses a combiner cabinet model, integrating the high and low voltage components. This makes the entire cabinet space very large. At the same time, the cabinet contains multiple wiring harnesses for high-voltage, low-voltage, and signals, making the internal structure very complex and very difficult to install and repair. If the battery system control box integrates both high-voltage and low-voltage control, it will increase the difficulty of control box design, the internal layout will be very complex, the space requirements will be very strict, and the overall cost will be higher. In addition, in ship design, the space inside the battery compartment is narrow, and in many scenarios, the large integrated cabinet solution such as a combiner cabinet is not suitable.

[0008] Technical Solutions

[0009] In the first aspect, an embodiment of the present application provides a low-voltage control distribution box, comprising a box body, a plurality of wiring guides and a plurality of wiring boards, wherein the box body is provided with a distribution cavity configured to place components and connecting wires; the wiring guide is arranged in the distribution cavity, and the wiring guide is slidably connected to a plurality of wiring terminal groups, and a partition block is provided between two adjacent wiring terminal groups. The wiring guide is also provided with a fixing member, and the fixing member is configured to limit the plurality of wiring terminal groups to the wiring guide; the wiring board includes a plurality of first wire boards, and a plurality of wire troughs are provided on the first wire board, and the plurality of first wire boards and the plurality of wiring guides are alternately arranged.

[0010] Beneficial effects

[0011] The present application provides a low-voltage control distribution box, which provides a distribution cavity within the box body for the installation and arrangement of various components used for power distribution, wherein the distribution cavity is provided with a plurality of wiring rails configured to install terminal blocks, and a plurality of wiring boards configured to install fixed connecting wires. The terminal blocks are installed on the wiring rails, and after sliding along the wiring rails to corresponding positions, they are fixedly connected to the wiring rails via fixing members. The plurality of first wiring boards are arranged alternately with the plurality of wiring rails, so that the terminal blocks on each wiring rail can cooperate with a first wiring board to achieve wiring. The operation is simple and convenient, which helps to keep the lines neat and clear, and also facilitates subsequent maintenance.

[0012] Furthermore, since the terminal blocks can be flexibly arranged by sliding on the wiring rails, operators can flexibly arrange the matching and arrangement of terminal blocks of different lengths according to wiring requirements and the space conditions within the distribution chamber during installation. This makes installation and wiring flexible and convenient, which helps improve the space utilization of the distribution chamber and reduces the design and wiring difficulty of the distribution box. Adjacent terminal blocks are also separated by partitions, which helps avoid mutual interference between the two adjacent terminal blocks and also helps operators quickly install and identify the corresponding terminal blocks, facilitating installation or subsequent maintenance. At the same time, the low-voltage control part is integrated into a box, which only contains low-voltage electricity, effectively ensuring the safety of the operator's work.

[0022] Modes for Carrying Out the Invention

[0023] As shown in Figures 1 to 6, a low-voltage control distribution box of this embodiment includes a box body 100, multiple wiring guides 200 and multiple wiring boards 300. The box body 100 is provided with a distribution cavity 110 configured to place components 800 and connecting wires; the wiring guide 200 is arranged in the distribution cavity 110, and the wiring guide 200 is slidably connected to multiple wiring terminal groups 400, and a partition block 500 is provided between two adjacent wiring terminal groups 400. The wiring guide 200 is also provided with a fixing member 600, which is configured to limit the multiple wiring terminal groups 400 to the wiring guide 200; the wiring board 300 includes multiple first line boards 300a, and the first line boards 300a are provided with multiple wire grooves 310. The multiple first line boards 300a and the multiple wiring guides 200 are alternately arranged.

[0024] In this embodiment, a power distribution chamber 110 is provided within the housing 100 to accommodate the installation and arrangement of various components 800 for power distribution. The power distribution chamber 110 includes a plurality of wiring rails 200 configured to accommodate terminal blocks 400, and a plurality of wiring boards 300 configured to accommodate fixed connecting wires. The terminal blocks 400 are mounted on the wiring rails 200, slid along the wiring rails 200 to corresponding positions, and then fixedly connected to the wiring rails 200 via fixing members 600. Furthermore, the alternating arrangement of the plurality of first wiring boards 300a with the plurality of wiring rails 200 allows each terminal block 400 on each wiring rail 200 to cooperate with a first wiring board 300a for wiring. This simplifies and facilitates operation, helps maintain neat and clear wiring, and facilitates subsequent maintenance.

[0025] Furthermore, since the terminal block groups 400 can be flexibly arranged by sliding on the wiring guide rails 200, the operator can flexibly arrange the matching and arrangement of terminal blocks 400 of different lengths according to the wiring requirements and the space conditions in the distribution chamber 110 during the installation operation, making the installation and wiring flexible and convenient, which is conducive to improving the space utilization rate of the distribution chamber 110 and reducing the design difficulty and wiring difficulty of the distribution box. The two adjacent terminal blocks 400 are also separated by a partition block 500, which is conducive to avoiding mutual influence between the two adjacent terminal blocks 400, and is also conducive to the operator's rapid installation and identification of the corresponding terminal block 400, so as to facilitate installation or subsequent maintenance. At the same time, the low-voltage control part is integrated into a box 100, and the box 100 only contains low-voltage electricity, so that the operator's work safety is effectively guaranteed.

[0026] In actual operation, the terminal block assembly 400 includes multiple terminal blocks 410. Different numbers of terminal blocks 410 are used according to the wiring requirements of different terminal blocks 400, thereby customizing the length of the terminal block assembly 400. This simplifies operation and avoids waste of the terminal block 400, thereby saving costs. Furthermore, it helps improve the space utilization of the distribution box by arranging terminal blocks 400 of different lengths.

[0027] Furthermore, in actual operation, as shown in FIG3 , the fixing member 600 is slidably mounted on the wiring guide rail 200. The fixing member 600 is provided with a locking through-hole 610. The horizontal projection of the locking through-hole 610 is located on the track plane 210 of the wiring guide rail 200. A fixing member such as a bolt passes through the locking through-hole 610 and presses against the track plane 210 of the wiring guide rail 200 to secure the fixing member 600 to the wiring guide rail 200. When securing the terminal block 400, the two fixing members 600 are slid respectively until they abut against the two sides of the terminal block 400. The fixing members 600 are then secured to the wiring guide rail 200 using bolts, thereby securing the terminal block 400 and preventing the terminal block 400 from slipping on the wiring guide rail 200.

[0028] In one embodiment, a control assembly is further included, comprising a control box 710, which is disposed within the power distribution chamber 110 and is connected to an external battery system. The housing 100 is provided with a wiring hole 160 that communicates with the power distribution chamber 110, and the control box 710 is electrically connected to the external battery system via the wiring hole 160. Thus, the operator only needs to control the battery system on the low-voltage control distribution box, avoiding contact with high voltage, which is beneficial for ensuring the operator's safety. Furthermore, other components within the power distribution chamber 110 can also be electrically connected to other external devices via the wiring hole 160, or to other external devices via the control box 710, to achieve corresponding control operations. The housing 100 is connected to a door 120 configured to open and close the power distribution chamber 110. The control assembly further comprises a plurality of control components 730 disposed on the outside of the housing 100 or the door 120, and the control components 730 are connected to the control box 710. The control component 730 includes a control button 731, a display screen 732 and a display light 733, so that the operator can directly view the data information of the battery system and operate the battery system outside the box 100, as well as perform corresponding control and monitoring operations on other equipment.

[0029] In one embodiment, the control assembly further includes an air switch 720 connected to the control box 710 and the terminal block 400. The air switch 720 is located within the power distribution chamber 110 and is configured to protect the overall power distribution control safety of the distribution box. In this embodiment, the air switch 720 is mounted on one of the wiring rails 200. The terminal block 300 further includes a third wiring board 300c having the same structure as the first wiring board 300a. The third wiring board 300c is located on one side of the wiring rail 200 where the air switch 720 is mounted and is configured to provide wiring for the air switch 720 and other components 800.

[0030] In one embodiment, the terminal block 300 also includes a second terminal block 300b having the same structure as the first terminal block 300a. The second terminal blocks 300b are disposed on both sides of the first terminal block 300a in the longitudinal direction, i.e., a second terminal block 300b is provided on both sides of the wiring rail 200 in the longitudinal direction. This allows for wiring of the connecting wires of the terminal block 400 toward both sides of the wiring rail 200 in the longitudinal direction, facilitating wiring operations for operators. The first terminal block 300a and the second terminal block 300b are disposed perpendicular to each other, facilitating the wiring of connecting wires in different routing directions and ensuring a neat and standardized arrangement of the interconnecting wires within the distribution box. This helps prevent arbitrary bending of the connecting wires, which can lead to confusion and affect wiring safety and subsequent maintenance.

[0031] In one embodiment, the box 100 is provided with fixing brackets 130, which secure the box 100 to the side panels of the hull. The fixing brackets 130 are positioned on either side of the box 100, allowing the box 100 to be fixedly hung in the cabin via the fixing brackets 130, thus saving installation space. Furthermore, compared to mounting the box 100 on the floor, hanging the box 100 sideways on the side panels of the hull can help reduce the likelihood of impact to the box 100. Buffers (not shown) are provided between the fixing brackets 130 and the side panels of the hull, providing a buffer between the distribution box and the hull. In this embodiment, the fixing brackets 130 are L-shaped metal frames, with one side of the L-shaped fixing bracket 130 connected to the side of the box 100 and the other side of the L-shaped fixing bracket 130 connected to the side panels of the hull, thereby securing the box 100 to the hull. The buffer can be a rubber pad, sponge pad or other elastic buffer component and structure, or a spring buffer structure. This is not limited in this embodiment. As long as the structure and design can achieve buffering between the box body 100 and the hull, such designs are within the scope of protection of this application.

[0032] In one embodiment, as shown in FIG4 , a terminal block 300a further includes a terminal base 320 . Multiple winding portions 330 are provided on the terminal base 320 . A wire slot 310 is formed between adjacent winding portions 330 . The connecting wires are threaded through the wire slots 310 to facilitate routing and securing the connecting wires. A bending head 331 is provided on the side of the winding portion 330 away from the terminal base 320 . The bending head 331 is V-shaped. The connecting wires are routed around the winding portions 330 . If the connecting wires escape, the wires move from the side of the winding portion 330 closer to the terminal base 320 toward the bending head 331 . At this point, the connecting wires located on the side of the opening 332 will slide into the opening 332 and be blocked by the opening 332, effectively preventing the connecting wires from escaping and ensuring the stability of the connecting wires. Furthermore, a bent protrusion 333 on the back side of the opening 332 also blocks the connecting wires located on the back side of the opening 332 , preventing them from escaping.

[0033] In actual operation, the V-shaped opening 332 of the bending head 331 is set towards or away from the wiring guide 200, which facilitates the wiring and fixation of the terminal block or other components 800 on the wiring guide 200. In addition, in addition to this embodiment, the bending head 331 can also adopt other structures and shapes such as U-shape, hook shape or semicircle, etc. As long as it can achieve the purpose of blocking the connecting wire in this embodiment to prevent the connecting wire from falling out, such designs are within the scope of protection of this application.

[0034] In one embodiment, a mounting base plate 140 is further provided within the distribution chamber 110. The wiring rails 200, terminal blocks 300, and various components 800 are all mounted on a mounting surface 141 of the mounting base plate 140. The side of the mounting base plate 140 facing away from the mounting surface 141 is connected to one inner side surface of the enclosure 100. The mounting base plate 140 and the enclosure 100 are connected via a plurality of mounting brackets 150. The mounting base plate 140 is provided with a plurality of mounting holes 142 for mounting the wiring rails 200, terminal blocks 300, and various components 800. To accommodate different distribution box installation and wiring requirements, different mounting base plates 140 can be replaced to accommodate the installation of the corresponding wiring rails 200, terminal blocks 300, and various components 800. The mounting base 140 and the box body 100 are connected by the mounting bracket 150. The mounting bracket 150 can also provide a buffer between the mounting base 140 and the box body 100, thereby reducing the impact of the vibration of the box body 100 on the mounting base 140 and the components 800 on the mounting base 140, which is beneficial to protecting the components 800 and ensuring the normal operation of the distribution box.
