[0031] The following is a detailed description of its overall specific settings and functions.

[0032] Reference Figure 1-Figure 5 As shown, in this embodiment: the upper surface of the cooling plate 6 is fixedly connected with an "L"-shaped plate 8, the inner wall of the "L"-shaped plate 8 is slidably connected with a pull rod 9, and the pull rod 9 is slidably connected to the inner wall of the slide 15.

By providing the limiting plate 16, a stable connection between the slide 15 and the pull rod 9 can be ensured.

[0033] A plurality of pointed protrusions 23 are fixedly connected to the side of the rectangular plate 17 close to the sponge strip 18. A sliding groove is provided on the upper surface of the "L"-shaped plate 8. A slider 12 is slidably connected to the surface of the sliding groove on the "L"-shaped plate 8. The slider 12 is fixedly connected to the card plate 11. By providing the pointed protrusions 23, the sponge strip 18 can be easily replaced. By providing the slider 12, the card plate 11 can be connected to the "L"-shaped plate 8. An arc-shaped plate 13 is fixedly connected to the side of the "L"-shaped plate 8 close to the card plate 11. A threaded rod 14 is threadedly inserted into the inner wall of the arc-shaped plate 13. The threaded rod 14 is rotatably connected to the surface of the card plate 11. By providing the arc-shaped plate 13, the rotation of the threaded rod 14 can be easily controlled. By providing the threaded rod 14, the movement of the card plate 11 can be easily controlled.

[0034] Working principle: when using the water cooling system device of the electric drive axle assembly, by starting the water pump 5, the coolant in the cooling water tank 3 is pumped out through the second water outlet pipe 4, and then passes through the cooling plate 6 and the water inlet pipe 7 into the electric drive axle body 1 to cool it. After that, the coolant that has absorbed heat in the electric drive axle body 1 enters the cooling water tank 3 again through the first water outlet pipe 2. When the cooling plate 6 needs to be cleaned, water is first injected into the rectangular plate 17 through the water injection bucket 22 and the water injection pipe 19. The water in the rectangular plate 17 enters the sponge strip 18, and then the threaded rod 14 is rotated to make the card plate 11 drive the slider 12 to slide on the surface of the slide groove on the "L"-shaped plate 8, so that the card block moves close to the curved plate 13, and the restriction on the position of the pull plate 10 is released. Then, the pull plate 10 drives the pull rod 9 to slide on the inner wall of the "L"-shaped plate 8, thereby driving the slide plate 15 and the rectangular plate 17 to move through the limit plate 16, so that the surface of the cooling plate 6 is cleaned through the sponge strip 18. After the cleaning is completed, the cover 21 is rotated away from the water outlet 20 to discharge the excess water in the rectangular plate 17, and then the cover 21 is installed on the water outlet 20, and the pull plate 1 is moved. 0 is close to the "L"-shaped plate 8, and the threaded rod 14 is rotated to make the card plate 11 move close to the pull plate 10, and the position of the pull plate 10 is restricted. By setting the rectangular plate 17 and the sponge bar 18, the cooling plate 6 can be easily cleaned. By setting the "L"-shaped plate 8, the pull plate 10 and the card plate 11, the position of the pull rod 9 and the rectangular plate 17 can be restricted, and the movement of the rectangular plate 17 when the sponge bar 18 is not in use can be avoided as much as possible. By setting the pointed protrusion 23, the sponge bar 18 can be easily replaced. By setting the water inlet, water can be injected into the rectangular plate 17, so that the sponge bar 18 can be soaked, thereby improving the cleaning effect of the sponge bar 18. By setting the water outlet 20, the excess water in the rectangular plate 17 can be easily discharged.
