In this way, the integration of the on-board charger housing 20 and the motor controller assembly housing 10 is realized. Since the first bottom shell 101 has a first water channel connection portion 110, the on-board charger housing 20 includes a second bottom shell 201 and a second side shell 202. The second bottom shell 201 has a heat dissipation water channel 210. The first water channel cover plate 30 is located between the second bottom shell 201 and the first bottom shell 101 and is connected to the second bottom shell 201. The first water channel cover plate 30 covers the heat dissipation water channel 210.

The first seal 50 and the second seal 60 are both hermetically connected between the first sealing groove 1101 and the first sealing boss 310, and are arranged axially with respect to the first water flow port. The third seal and the fourth seal are both hermetically connected between the second sealing groove and the second sealing boss, and are arranged axially with respect to the second water flow port.

[0064] The materials of the first and second sealing members 50 and 60 include, but are not limited to, rubber or silicone. The materials of the first and second sealing members 50 and 60 can be the same or different. The first sealing member 50 can be a sealing ring. In other words, the first sealing member 50 can be annular. The second sealing member 60 can be a sealing ring. In other words, the second sealing member 60 can be annular. The first and second sealing members 50 and 60 can surround the first sealing boss 310. Similar to the first and second sealing members 50 and 60, the materials of the third and fourth sealing members include, but are not limited to, rubber or silicone. The materials of the third and fourth sealing members can be the same or different. The third sealing member can be a sealing ring. In other words, the third sealing member can be annular. The fourth sealing member can be a sealing ring. In other words, the fourth sealing member can be annular. The third and fourth sealing members can surround the second sealing boss.

[0065] In this embodiment, the first seal 50 and the second seal 60 can form a double seal along the axial direction of the first water flow outlet, thereby improving the sealing effect between the second water channel connection part 301 and the first water channel connection part 110. The third seal and the fourth seal can form a double seal along the axial direction of the second water flow outlet, thereby improving the sealing effect between the fourth water channel connection part 302 and the third water channel connection part 112.

[0066] In one possible embodiment, please refer to Figures 9 to 12 , Figure 10 for Figure 1The schematic structural diagram of the first water channel cover plate 30 in the electric control housing assembly 100 is shown. Figure 11 for Figure 1 The schematic structural diagram of the first sealing member 50 in the electric control housing assembly 100 is shown in FIG. Figure 12 for Figure 1 The following is a schematic diagram of the structure of the second sealing member 60 in the electronic control housing assembly 100. The first sealing groove 1101 includes a first end surface 110a and a first peripheral side surface 110b. The first sealing boss 310 includes a second end surface 3101 and a second peripheral side surface 3102. The second end surface 3101 and the first end surface 110a are arranged opposite each other along the axial direction of the first water flow outlet. The first peripheral side surface 110b surrounds the second peripheral side surface 3102. The first sealing member 50 abuts between the second end surface 3101 and the first end surface 110a. The second sealing member 60 abuts between the second peripheral side surface 3102 and the first peripheral side surface 110b.

[0067] It is understandable that the orientation of the first end face 110a is different from that of the first circumferential side face 110b, and the orientation of the second end face 3101 is different from that of the second circumferential side face 3102. In this embodiment, the first sealing member 50 abuts between the second end face 3101 and the first end face 110a, thereby forming an end face seal between the second water channel connection portion 301 and the first water channel connection portion 110. The second sealing member 60 abuts between the second circumferential side face 3102 and the first circumferential side face 110b, thereby forming a radial seal between the second water channel connection portion 301 and the first water channel connection portion 110. In this manner, the first sealing member 50 and the second sealing member 60 are simple and convenient to install and remove, and there is no need to worry about eccentric leakage caused by precision problems in the radial seal. At the same time, enhanced sealing protection of the end faces is achieved, making the double sealing effect between the second water channel connection portion 301 and the first water channel connection portion 110 more reliable.

[0068] In a possible embodiment, similar to the first sealing groove 1101 and the first sealing boss 310 in the above embodiment, the second sealing groove includes a third end face and a third circumferential side face, the second sealing boss includes a fourth end face and a fourth circumferential side face, the fourth end face and the third end face are arranged opposite to each other along the axial direction of the second water flow outlet, the third circumferential side face surrounds the third circumferential side face, the third sealing member abuts between the fourth end face and the third end face, and the fourth sealing member abuts between the fourth circumferential side face and the third circumferential side face.

[0069] It is understandable that the orientation of the third end face is different from the orientation of the third peripheral side face, and the orientation of the fourth end face is different from the orientation of the fourth peripheral side face. In this embodiment, the third sealing member abuts between the fourth end face and the third end face, so that an end face seal is formed between the fourth water channel connection portion 302 and the third water channel connection portion 112, and the fourth sealing member abuts between the fourth peripheral side face and the third peripheral side face, so that a radial seal is formed between the fourth water channel connection portion 302 and the third water channel connection portion 112. In this way, the installation and removal of the third and fourth sealing members are simple and convenient, and there is no need to worry about eccentric leakage caused by precision problems of the radial seal. At the same time, the end face is strengthened with sealing protection, which can make the double sealing effect between the fourth water channel connection portion 302 and the third water channel connection portion 112 more reliable.

[0070] In one possible embodiment, please refer to Figure 8 and Figure 9 A first receiving groove 30a is formed between the first end surface 110a and the second end surface 3101, and a portion of the first sealing member 50 is received in the first receiving groove 30a.
