Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] The electric drive system of new energy vehicles includes a motor, an inverter, a reducer, a control controller and a cold zone system, and these components are arranged on the housing of the electric drive system.

[0041] Figure 2 An exploded view of an electric drive system housing provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 2As shown, the motor housing 3 includes an integrated housing 301 and a rear end cover 302 , and the reducer housing 2 and the rear end cover 302 are respectively connected to opposite ends of the integrated housing 301 .

[0042] Figure 3 A top view of a controller housing of an electric drive system housing provided in an embodiment of the present disclosure. Figure 4 A bottom view of a controller housing of an electric drive system housing provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 3 and 4 As shown, the first side wall 101 of the controller housing 1 is provided with a water inlet 103, the side of the controller housing 1 close to the motor housing 3 is provided with a water outlet 104, and a water flow channel 105 is provided inside the controller housing 1, which is connected to the water inlet 103 and the water outlet 104 respectively.

[0043] It should be noted that the water flow channel 105 is arranged inside 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 connected to an external cooling device, and the cooling liquid is heat exchanged at the external cooling device, thereby circulating and cooling the controller. The cooling liquid can be ionized water, ethylene glycol solution or other special cooling liquid, so as to meet the requirements of high thermal conductivity and low corrosion for circulating cooling.

[0044] In some embodiments of the present disclosure, Figure 3 As shown, a power module interface 106 is provided on one side of the controller housing 1 away from the motor housing 3, and the water flow channel 105 is connected to the power module interface 106. Specifically, the power module interface 106 includes a power module water outlet 1061 and a power module water inlet 1062. The cooling liquid can flow into the power module through the power module water inlet 1062, and flow out from the power module water outlet 1061 to the water flow channel 105 of the controller housing 1, thereby circulating and cooling the power module. The water flow channel 105 can have a multi-section bending structure, thereby expanding the coverage area of ​​the water flow channel 105 to improve the cooling effect on the controller.

[0045] In some embodiments of the present disclosure, 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 sequentially connected with the power module interface 106 and the inverter module interface 107. Specifically, the inverter module interface 107 includes an inverter module water outlet 1071 and an inverter module water inlet 1072, and the water flow channel 105 is respectively connected with the inverter module water inlet 1072 and the inverter module water outlet 1071. The coolant housing flows into the inverter module through the inverter module water inlet 1072, flows out of the inverter module from the inverter module water outlet 1071, and enters the water flow channel 105 of the controller housing 1, thereby circulating and cooling the inverter module.

[0046] In the controller housing 1 provided by the embodiment of the present disclosure, the cooling liquid enters the water flow channel 105 through the water inlet 103, enters the power module through the power module water inlet 1062, returns to the water flow channel 105 from the power module water outlet 1061, flows into the inverter module through the inverter module water inlet 1071, and then flows out to the water flow channel 105 through the inverter module water outlet 1072. Among them, the multiple sections of water flow channels 105 in the controller housing 1 are directly formed by the core-pulling structure.

[0047] Optionally, a plurality of temperature sensors may be provided in the controller housing 1, and the temperature sensors are used to monitor the temperature of the controller in real time, and can control the liquid flow in the water flow channel 105 according to the temperature of the controller to adjust the cooling effect on the controller.

[0048] Figure 5 A schematic diagram of a motor housing of an electric drive system housing provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 5 As shown, a side of the rear end cover 302 away from the integrated housing 301 is provided with a plurality of air compressor mounting parts 303. The plurality of air compressor mounting parts 303 are used to fix the rear end cover 302 to the air compressor. The plurality of air compressor mounting parts 303 can be used to install the air compressor without using an air compressor mounting bracket, which is conducive to cost saving. Exemplarily, a side of the rear end cover 302 away from the integrated housing 301 is provided with four air compressor mounting parts 303.

[0049] In some embodiments of the present disclosure, Figure 5 As shown, a side of the rear end cover 302 away from the integrated housing 301 is provided with a plurality of suspension mounting parts 304. The plurality of suspension mounting parts 304 are used to connect the rear end cover 302 to the suspension, thereby improving the stability and reliability of the overall structure. Exemplarily, a side of the rear end cover 302 away from the integrated housing 301 is provided with four suspension mounting parts 304.

[0050] It should be noted that the fixed connection involved in the embodiment of the present disclosure may be a welding connection or a threaded connection. For example, the air compressor mounting portion 303 and the suspension mounting portion 304 are both threaded holes, so that the air compressor and the suspension can be fixedly mounted on 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 respectively integrally die-cast. 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 using magnesium alloy die-casting has a smaller weight, which is beneficial to reducing the weight of the entire vehicle. Compared with the split housing, 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, and can also reduce the assembly process to reduce costs and effectively reduce the risk of sealing failure.
