[0042] Figure 3 A top view of the controller housing of the electric drive system housing provided by the embodiments of the present disclosure. Figure 4 A bottom view of the controller housing of the electric drive system housing provided by the embodiments of the present disclosure. In some embodiments of the present disclosure, as shown in FIG. 2, the first side wall 101 of the controller housing 1 is provided with a water inlet 103, and the side of the controller housing 1 close to the motor housing 3 is provided with a water outlet 104.

The controller housing 1 is provided with a water flow channel 105, and the water flow channel 105 is in communication with the water inlet 103 and the water outlet 104 respectively.

[0043] It should be noted that the water flow channel 105 is arranged in the interior of the controller housing 1, and the water flow channel 105 is a hollow cavity. The cooling liquid circulates in the water flow channel 105, thereby cooling the controller. The water inlet 103 and the water outlet 104 can be in communication with an external cooling device. The cooling liquid is heat exchanged at the external cooling device, thereby circulating the cooling of the controller. The cooling liquid can be ionized water, ethylene glycol solution or other special cooling liquid, thereby being able to meet the requirements of high thermal conductivity and low corrosion of circulating cooling.

[0044] In some embodiments of the present disclosure, as shown in FIG. 2, the side of the controller housing 1 away from the motor housing 3 is provided with a power module interface 106, and the water flow channel 105 is in communication with the power module interface 106.

The cooling liquid can flow into the power module through the power module water inlet 1062, flow out of the power module water outlet 1061 into the water flow channel 105 of the controller housing 1, thereby circulating the cooling of the power module. The water flow channel 105 can have a multi-bend structure, thereby expanding the coverage area of the water flow channel 105 to improve the cooling effect of the controller.

[0045] In some embodiments of the present disclosure, as shown in FIG. 2, the side of the controller housing 1 away from the motor housing 3 is provided with a power module interface 106, and the water flow channel 105 is in communication with the power module interface 106. Figure 3As shown, the side of the controller housing 1 away from the motor housing 3 is provided with an inverter module interface 107, and the water flow channel 105 is in communication with the power module interface 106 and the inverter module interface 107 in sequence.

In some embodiments of the present disclosure, as shown in Figure 5 The rear end cover 302 away from the integrated housing 301 is provided with a plurality of air compressor mounting portions 303. The plurality of air compressor mounting portions 303 are used to fixedly connect the rear end cover 302 and the air compressor, and the plurality of air compressor mounting portions 303 can install the air compressor without using the air compressor mounting bracket, which is beneficial to save costs. Exemplarily, the rear end cover 302 away from the integrated housing 301 is provided with four air compressor mounting portions 303.

[0049] In some embodiments of the present disclosure, as shown in Figure 5 The rear end cover 302 away from the integrated housing 301 is provided with a plurality of suspension mounting portions 304.

Exemplarily, the rear end cover 302 away from the integrated housing 301 is provided with four suspension mounting portions 304.

[0050] It should be noted that the fixed connection involved in the embodiments of the present disclosure can be a welding connection or a threaded connection. For example, the air compressor mounting portion 303 and the suspension mounting portion 304 are threaded holes, so that the air compressor and the suspension can be fixedly mounted to the rear end cover 302.

[0051] In some embodiments of the present disclosure, the controller housing 1, the reducer housing 2, the integrated housing 301, and the rear end cover 302 are integrally pressure cast, respectively. The main material of the controller housing 1, the reducer housing 2, the integrated housing 301, and the rear end cover 302 is aluminum alloy or magnesium alloy. The electric drive system housing pressure cast with magnesium alloy has smaller weight, which is beneficial to reduce the mass of the whole vehicle. The integrally formed controller housing 1, reducer housing 2, integrated housing 301, and rear end cover 302 have higher strength and better vibration modal performance compared with the split housing, and can also reduce the assembly process, reduce the cost, and effectively reduce the risk of sealing failure.

[0056] In the vehicle provided in this embodiment, both the first sidewall 101 and the second sidewall 102 of the controller housing 1 are provided with a fast-charging connector and a DC-DC connector. The fast-charging connector is used for electrical connection with the high-voltage power distribution unit, and the DC-DC connector is used for electrical connection with the power module.
