[0030] Example:

[0031] This embodiment discloses the structure of the high-voltage box cabinet.

[0032] like Figure 1 and Figure 4 As shown, the high-voltage box cabinet structure includes a box body 1, a mounting plate 2, a first bracket 21, a circuit breaker 3, and a box cover 7.

[0033] The enclosure 1 has a hollow structure with an upward-facing opening, including a positive input terminal 11, a negative input terminal 12, a positive output terminal 13, and a negative output terminal 14. These terminals are mounted on the front panel of the enclosure 1. A mounting plate 2 is located at the bottom inner side of the enclosure 1 and includes a first bracket 21, with its first end mounted on the mounting plate 2. A circuit breaker 3 is fixed to the second end of the first bracket 21 and is electrically connected to the positive input terminal 11, negative input terminal 12, positive output terminal 13, and negative output terminal 14 to form a control circuit, controlling the connection and disconnection between the input and output terminals. A cover 7 is fixed to the top of the enclosure 1. For example, the enclosure 1 is made of galvanized cold-rolled steel sheet, integrally bent and welded. The input and output ports are connected to the positive and negative terminals of an external power source, respectively. The first bracket 21 is a right-angle sheet metal structure with a first horizontal plate and a first vertical plate that are perpendicular to each other. The first horizontal plate is screwed to the mounting plate 2, and the circuit breaker 3 is connected to the front end of the first vertical plate. The cover 7 is welded to the upper end of the box body 1 and fixed by bolts, press-fitting, or riveting.

[0034] like Figure 1 and Figure 4 As shown, the housing 1 further includes a switch 15, which is disposed on the front panel of the housing 1 and connected to the adjustment terminal of the circuit breaker 3 via a rod. The switch 15 can manually control the circuit breaker 3 to connect or disconnect the control circuit.

[0035] like Figure 4 and Figure 5 As shown, the mounting plate 2 further includes a second bracket 22 and a BMS battery management system 8, with the first ends of the second bracket 22 and the BMS battery management system 8 mounted on the mounting plate 2. The high-voltage box cabinet structure includes a sensor 4, which is mounted on the second end of the second bracket 22. The sensor 4 and the BMS battery management system 8 are electrically connected to the control circuit. The sensor 4 detects parameters in the control circuit, and the BMS battery management system 8 receives the detection results from the sensor 4 and controls the circuit breaker 3 to connect or disconnect the control circuit. For example, the second bracket 22 is a right-angle sheet metal with a second horizontal plate and a second vertical plate that are perpendicular to each other. The second horizontal plate is screwed to the mounting plate 2, and the sensor 4 is connected to the rear end of the second vertical plate. The sensor 4 is a Hall sensor.

[0036] like Figure 4 and Figure 5 As shown, the housing 1 further includes a third bracket 23 and a fan 5. The first end of the third bracket 23 is located on the inner side of the housing 1, and the fan 5 is located on the second end of the third bracket 23. For example, the third bracket 23 is a right-angle sheet metal structure with mutually perpendicular third and fourth vertical plates. The third vertical plate is screwed to the side of the housing 1, and the fan 5 is connected to the rear end of the fourth vertical plate. For example, the housing 1, the first bracket 21, the second bracket 22, and the third bracket 23 are made of galvanized cold-rolled steel, and the mounting plate 2 is made of aluminum-zinc-magnesium steel, which has high corrosion resistance.

[0037] like Figure 1 As shown, the housing 1 further includes a handle 16, which is located on the front panel of the housing 1 to facilitate the removal and placement of the high-voltage box.

[0038] like Figure 1 As shown, the enclosure 1 further includes fixing ears 17, which are disposed on both front ends of the enclosure 1 for easy installation and fixing of the high-voltage box. For example, the handle 16 and the fixing ears 17 are made of 304 stainless steel.

[0039] like Figure 3 As shown, the enclosure 1 further includes an inner edge 18, which is disposed around the upper perimeter of the enclosure 1. The cover 7 includes foam 6, which is disposed on the top inner side of the cover 7, corresponding to the inner edge 18. For example, the foam 6 is 4mm EPDM foam, and a ring-shaped edging 71 extends from the lower end of the cover 7, so that the high-voltage box as a whole achieves an IP56 protection level, improving the sealing performance and safety of the high-voltage box.

[0040] like Figure 2As shown, the housing 1 further includes a grounding post, which is disposed on the front panel of the housing 1. The sensor 4 and the BMS battery management system 8 are connected to the grounding post through a grounding wire.

[0041] In this embodiment, by setting an mounting plate 2 at the bottom of the enclosure 1, and setting a bracket on the mounting plate 2, the internal equipment such as the circuit breaker 3 is installed on the bracket at the end away from the bottom of the enclosure 1. During installation and disassembly, the internal equipment such as the circuit breaker 3 and the bracket are simply removed from the housing together, making installation and disassembly convenient. At the same time, since the internal equipment such as the circuit breaker 3 does not directly contact the enclosure 1, the impact of external vibration or impact on the internal equipment is small, and the high voltage box has high safety.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
