Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0027] like Figure 3 and Figure 4 As shown, an integrated electrical control device includes a housing 2, which comprises a motor housing 3 and an electrical control housing 4. The motor housing 3 houses a stator assembly and a rotor assembly, while the electrical control housing 4 houses the electrical control components. The electrical control housing 4 is located on the rear end cover 31 of the motor housing 3, and the electrical control housing 4 and the rear end cover 31 are integrally formed. Specifically, the electrical control housing 4 and the rear end cover 31 are integrally cast. Integrating the electrical control housing 4 integrally onto the rear end cover 31 of the motor to form a single component integrates the motor and the motor controller, reducing the overall size, lowering costs, and offering advantages such as reduced wiring harness connections and increased reliability.

[0028] like Figure 3 As shown, the equipment housing 2 also includes a large cover 5. The electrical control housing 4 has an opening on the side away from the motor housing 3. The large cover 5 can be detachably installed at the opening to protect the electrical control components inside the electrical control housing 4.

[0029] Specifically, the electrical control components include a control drive board 41, a three-phase copper busbar 42, a three-phase copper column 43, a drive module 46 (IGBT), a film capacitor 48, and a magnetic ring 49. The control drive board 41 processes high-voltage and low-voltage signals to control the motor; the three-phase copper column 43 and the three-phase copper busbar 42 connect the control drive board 41 and the drive module 46 for three-phase power transmission; the drive module 46 converts DC to AC, performing an inverter function; and the film capacitor 48 and the magnetic ring 49 perform rectification and filtering functions.

[0030] In this application, the thin-film capacitor 48 and the magnetic ring 49 are preferably integrated injection molded structures, which saves space and costs.

[0031] like Figure 5 As shown, in a further preferred embodiment, the control drive board 41 integrates a control circuit 411 and a drive circuit 412 to process high-voltage signals and low-voltage signals respectively. Integrating the control circuit 411 and the drive circuit 412 on a single circuit board can save costs and facilitate assembly.

[0032] like Figure 3As shown, an independent heat sink 47 is detachably installed inside the electrical control box 4, and the drive module 46 is detachably installed on the surface of the heat sink 47, such as by bolts. The heat generated by the drive module 46 during operation can be transferred to the electrical control box 4 through the heat sink 47 to achieve heat dissipation. The structure of the heat sink 47 is adapted to the structure of the drive module 46.

[0033] Since different motors require different drive modules 46, different heat sinks 47 are needed. At the same time, the equipment housing 2 is mass-produced using high-pressure casting, which is very expensive. Modifying the structure of the equipment housing 2 requires re-molding, which will result in cost waste. However, this application uses an independent heat sink 47 for heat dissipation. Different drive modules 46 can be adapted by changing the heat sink 47 without changing the equipment housing 2, thereby effectively reducing costs.

[0034] In this application, a junction box 44 is provided inside the electrical control box 4. The junction box 44 is located outside the three-phase copper busbar 42 and fixes the three-phase copper busbar 42. A shielding cover 45 is also provided inside the electrical control box 4. The shielding cover 45 is installed above the junction box 44 and is used to shield the high-voltage signal of the three-phase copper busbar 42 to prevent the low-voltage signal on the control drive board 41 from being interfered with.

[0035] A DC input terminal 32 is provided on the circumferential end face of the motor housing 3 for connecting a DC wiring harness. A small cover plate 33 is provided at the opening of the DC input terminal 32 to protect the wiring harness connection position.

[0036] This utility model's integrated electrical control equipment integrates the electrical control box into the rear end cover of the motor to form a single component, thereby integrating the motor and motor controller together. It also integrates the thin-film capacitor and magnetic ring into one unit, and integrates the control circuit and drive circuit into a single control drive board. This reduces the overall size of the machine and has advantages such as reducing wiring harness connections and increasing reliability. At the same time, the use of an independent heat sink design can reduce costs.

[0037] In the description of this specification, unless otherwise expressly defined, the terms "setup", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0038] While specific embodiments of this utility model have been described above, those skilled in the art should understand that the described embodiments are merely some, not all, embodiments of this utility model. These are merely illustrative examples, and the scope of protection of this utility model is defined by the claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model and without any inventive effort, but all such changes and modifications fall within the scope of protection of this utility model.
