On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] It should be understood that the terms used in the text are only for the purpose of describing specific example embodiments, and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used in the text may also be meant to include plural forms. The terms "include", "comprise", "contain", and "have" are inclusive, and therefore specify the existence of stated features, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not interpreted as necessarily requiring them to be performed in the specific order described or illustrated, unless the execution order is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0037] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0038] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure is turned over, then the elements described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0039] like Figures 1 to 5 As shown, Figure 1 The direction a is the depth direction of the second accommodating cavity 12, that is, the depth direction of the first accommodating cavity 11. According to the implementation mode of the utility model, the first aspect of the utility model proposes an electric control cabinet, which includes a cabinet body 10. The cabinet body 10 defines a first accommodating cavity 11 and a second accommodating cavity 12.

[0040] It is understandable that the energy storage device is a device that stores electricity through a battery and releases it when needed. The energy storage device will release heat when it is running, so a thermal management system needs to be set up to manage it thermally. The thermal management system can use an air cooling unit to cool it down by taking away the heat with cold air. The air cooling unit is provided with an electric control cabinet, and its interior is used to set air switches 40, instruments, control devices, and electronic devices 41 such as protective electrical appliances.

The first accommodating cavity 11 and the second accommodating cavity 12 can be provided with an installation structure for installing the electronic device 41. The depths of the two accommodating cavities are different, so that two partitions are formed inside the cabinet 10. In actual use, the high and low voltages can be divided into different partitions to improve safety. In addition, the electric control cabinet of the utility model can also be applied to other equipment, such as HVAC equipment, air conditioning equipment, etc.

[0041] The utility model divides the internal space of the electric control cabinet into a first accommodating cavity 11 and a second accommodating cavity 12 of different depths, so that the user can install different electronic devices 41 in the first accommodating cavity 11 or the second accommodating cavity 12 according to actual needs. For example, the first accommodating cavity 11 is used as an installation area for high-voltage electronic devices 41, and the second accommodating cavity 12 is used as an installation area for low-voltage electronic devices 41, so that the layout of the electronic devices 41 in the electric control cabinet is neat, the high and low voltages are separated, and the safety is standardized.

The transition plate 14 can be set at an angle with the first bottom plate 13 and the second bottom plate 15, that is, the transition plate 14 extends from the first bottom plate 13 to the second bottom plate 15. The structure of the inclined setting of the transition plate 14 makes the appearance of the electric control cabinet more beautiful, and the folding angle of the bottom plate assembly is more gentle, which reduces the adverse effect of the folding angle on the wiring harness and facilitates the wiring.

[0046] like Figures 1 to 3 As shown, in some embodiments of the present invention, the transition plate 14 is provided with a threading hole 141 for allowing the wire harness of the electronic device 41 to pass through.

[0051] It can be understood that the mounting frame 20 can be a bracket-type structure, such as a C-shaped or L-shaped bracket. One side of the mounting frame 20 can be welded to the base plate assembly, and the other side of the mounting frame 20 can be provided with a mounting groove or a mounting hole 231, and a bolt hole can also be provided to fix the wire controller 42 in the mounting groove or the mounting hole 231. The wire controller 42 can also be fixed to the mounting frame 20 with bolts. The mounting frame 20 sets the wire controller 42 in the second mounting cavity, so that the wiring harness at the rear end of the wire controller 42 can be easily passed through or connected to other electronic devices 41.

The first mounting plate 22 is connected to the side plate assembly 16. The second mounting plate 23 is provided with a mounting hole 231 for embedding and mounting the wire controller 42.

[0053] It is understandable that the mounting frame 20 can be made of sheet metal or welded together by multiple metal plates. The first mounting plate 22 and the second mounting plate 23 can be rectangular plate structures. The first mounting plate 22 can be connected to the side panel assembly 16 through a connector 24.
