[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-6 The diagram shows a waterproof structure for an electric vehicle controller, comprising a housing 1, a first guide plate 12, a drainage mechanism, and a protective mechanism. A connecting pipe 6 is fixedly connected to the outer wall of the housing 1, and a main control board 10 is fixedly connected to the inner wall of the housing 1. The main control board 10 is used to control control signals. An end cover 3 is movably disposed on the top of the housing 1, and a heat dissipation vent 4 is opened on the outer wall of the end cover 3. A fixing plate 15 is fixedly connected to the inner cavity of the housing 1. The first guide plate 12 is fixedly connected to the top of the fixing plate 15 and is disposed below the heat dissipation vent 4. The drainage mechanism is disposed below the first guide plate 12 and is used to collect and drain water. The protective mechanism is disposed inside the connecting pipe 6 and is used to prevent water from entering the housing 1 through the connecting pipe 6. The first guide plate 12 catches the rainwater entering from the heat dissipation vent 4 and then guides the rainwater into the drainage mechanism, and then discharges it from the housing through the drainage mechanism. At the same time, the protective mechanism inside the connecting pipe 6 absorbs the rainwater flowing in from the connecting pipe 6, protecting the main control board 10 and preventing the controller from short-circuiting due to water immersion.

[0026] On one hand, a second guide plate 13 is fixedly connected to the bottom of the heat dissipation vent 4. The two guide plates 13 are matched in a V-shape. A sealing gasket 5 is fixedly connected to the top of the shell 1. A bolt 20 is threadedly connected between the end cover 3 and the shell 1. Workers fix the end cover 3 and the shell 1 with the bolt 20. The end cover 3 is used to squeeze the sealing gasket 5. The sealing gasket 5 prevents rainwater from entering from the connection between the end cover 3 and the shell 1. The drainage mechanism includes a water collection tank 9, which is fixedly connected to the inner cavity of the shell 1. The water collection tank 9 is located below the bottom of the first guide plate 12. The outer wall of the shell 1 is fixed. A drain pipe 7 is fixedly connected to the water collection tank 9. The drain pipe 7 extends into the water collection tank 9. A duckbill valve 8 is fixedly connected to the end of the drain pipe 7 away from the water collection tank 9. The duckbill valve 8 allows water inside the water collection tank 9 to flow out, while preventing external water from flowing back into the water collection tank 9. Rainwater entering from the heat dissipation vent 4 is guided by the second guide plate 13 to the middle of the first guide plate 12 to prevent rainwater from splashing onto the main control board 10. The first guide plate 12 is set at an angle, guiding the rainwater into the water collection tank 9. Finally, the rainwater is discharged through the drain pipe 7 and the duckbill valve 8, completing the drainage work.

[0027] On the other hand, a heating box 2 is fixedly connected to the outer wall of the shell 1. A heating plate is installed inside the heating box 2. There are two heating boxes 2 arranged symmetrically. A water-absorbing sponge 11 is fixedly connected to the inner wall of the heating box 2. The water-absorbing sponge 11 can absorb the water vapor inside the shell 1 to further improve the waterproof ability. After the water is absorbed, the heating box 2 is started and the heating box 2 heats the water-absorbing sponge 11 to improve the drying rate of the water-absorbing sponge 11.

[0028] In addition, the protective mechanism includes a first movable plate 17, which is disposed inside the connecting pipe 6. A deep groove 14 is formed on the outer wall of the first movable plate 17, and a second movable plate 18 is movably disposed inside the deep groove 14. Waterproof pads 19 are fixedly connected to the inner walls of the first movable plate 17 and the second movable plate 18. Threaded control rods 16 are rotatably connected to the outer walls of the first movable plate 17 and the second movable plate 18. The threaded control rods 16 are threadedly connected to the inner wall of the connecting pipe 6. The connecting pipe 6 is used to connect the line. When installing the line, the worker rotates the threaded control rods 16, which drives the first movable plate 17 and the second movable plate 18 to move until the waterproof pads 19 on the surface of the first movable plate 17 and the second movable plate 18 are in contact with the outer wall of the line. If rainwater flows down from the surface of the line, it can be absorbed by the waterproof pads 19.

[0029] In specific operation: rainwater entering from the heat dissipation vent 4 is guided by the second guide plate 13 to the middle of the first guide plate 12 to prevent rainwater from splashing onto the main control board 10. The first guide plate 12 is set at an angle and guides the rainwater into the water collection tank 9. Finally, it is discharged through the drain pipe 7 and the duckbill valve 8 to complete the drainage work. The water-absorbing sponge 11 can absorb the moisture inside the shell 1 to further improve the waterproof ability. After the water absorption is completed, the heating box 2 is started. The heating box 2 heats the water-absorbing sponge 11 to increase the drying rate of the water-absorbing sponge 11. The worker rotates the threaded control rod 16, which drives the first moving plate 17 and the second moving plate 18 to move until the waterproof pads 19 on the surface of the first moving plate 17 and the second moving plate 18 are in contact with the outer wall of the line. If rainwater flows down from the surface of the line, it can be absorbed by the waterproof pads 19.
