[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1As shown, a high-voltage control box is primarily used in the "aircraft and automotive" fields and requires multiple functions. This control box represents a further design improvement on the original, integrating multiple control functions while ensuring a compact and safe design. The control box's structural design includes a control box housing 1, which is formed by one-piece die-casting of aluminum profiles. This ensures structural integrity, reduces connections, improves sealing and waterproofing, and increases its service life.

[0023] The control box housing 1 has several holes pre-drilled on one end face for installing and connecting high-current connectors 11 and signal connectors 12. The other end face of the control box housing 1 also has several holes for installing and connecting high-current connectors 11. One side of the control box housing 1 is connected to a wall-penetrating end 13, and a vent valve 14 is provided on one side of the wall-penetrating end 13 for connection and fixation to the side wall of the control box housing 1. The bottom of the control box housing 1 is connected to four connecting limit blocks 15, which have bolt connection holes for bolts to pass through, thereby limiting and fixing the control box housing 1. Furthermore, the interior of the control box housing 1 is divided into several chambers, each for installing and connecting different control units.

[0024] An example of a control unit (including a control unit circuit board) installed inside the control box housing 1 is as follows:

[0025] The corresponding chambers of the control box housing 1 are installed and connected sequentially and neatly according to the design requirements, including:

[0026] The system includes high-voltage contactor units, high-current through-wall terminal units, connector units, control system units, copper busbar units, high-voltage fuse units, reverse connection protection units, and communication interface units. These control units are electrically connected via cables and then used in conjunction with display systems and control systems to provide human-machine interaction functions such as remote terminal data transmission, data feedback, and data operation, thereby enabling real-time monitoring of aircraft and vehicle data operation.

[0027] Furthermore, the control box housing 1 has several ventilation holes on its side wall. A ventilation fan is installed inside the control box housing 1 near the ventilation holes, and the ventilation fan is electrically connected to the control circuit inside the control box housing 1. By electrically installing the ventilation fan at a suitable position on the control box housing 1, namely at the ventilation holes, the ventilation and heat dissipation of the entire control box are increased. A dust screen is detachably installed on the outer wall of the control box housing 1 near the ventilation holes using screws; this dust screen prevents external dust, rainwater, etc., from entering the control box and affecting the control circuit boards inside the control box.

[0028] Furthermore, the bottom surface of the control box housing 1 is provided with adjustable lifting components around its perimeter. Each lifting component includes a bolt rod, one end of which is threadedly connected to the bottom of the control box housing, and the other end of which is connected to a support plate. The bolt rod allows for height adjustment of the control box housing 1 relative to its placement surface, thereby ensuring better ventilation and heat dissipation, as well as stability of the entire control box housing.

[0029] Furthermore, the control box housing 1 has several connecting partitions inside. The connecting partitions are fixed to the bottom surface of the control box housing 1 with screws. The connecting partitions have several bolt holes for mounting and connecting control unit circuit boards. The connecting partitions can be used to install and connect other control units (including control circuit boards, etc.), thereby enabling the control box housing 1 to perform more functions. The separation of the "connecting partitions" ensures that there is more installation space inside, while also making the installation position more orderly and avoiding wiring errors.

[0030] Furthermore, a cable channel is provided at the bottom of the control box housing 1 for cables electrically connected to the control unit circuit board inside the control box housing 1. The cable channel is equipped with a limiting clamp for cable positioning. Several limiting clips for cable positioning are detachably connected by screws to the side of the control box housing 1 near the cable channel. This design allows cables connected to the inside of the control box housing 1 to pass through the cable channel 18 and, under the limiting clamp's control, to enter the control box housing 1 neatly and rationally. The limiting clips also limit and organize different cables, serving a cable management function and preventing internal wiring tangles and incorrect cable connections.

[0031] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the embodiments described above. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.
