[0002] The electric vehicle controller is a core control device used to control the starting, running, forward and backward movement, speed, and stopping of the electric vehicle motor, as well as other electronic components of the electric vehicle. It is like the brain of the electric vehicle and is an important component. It is mainly composed of peripheral devices such as resistors, sensors, and bridge switching circuits, as well as the main chip or microcontroller.

[0003] When in use, controllers are often designed with sealed housings to protect internal components and prevent water from entering the electric vehicle in rainy weather. However, most existing controllers have poor sealing or are difficult to disassemble. Some controllers with good sealing are difficult to disassemble, while controllers that are easy to disassemble often cannot guarantee sealing. Summary of the Invention

[0004] To address the problems of poor sealing or difficult disassembly of existing controllers during use, this invention provides a waterproof controller to solve the aforementioned issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waterproof controller includes a controller body, a connecting frame fixed to one end of the controller body, a sealing cover plate covering the outer side of the sealing gasket, a sealing gasket plate fixed to the outer edge of the controller body on the side of the sealing cover plate, a sealing clip frame fixed to the side of the sealing cover plate near the inside of the controller body, the sealing clip frame engaging and inserting into the inside of the controller body, and clamping components symmetrically arranged on each side of the sealing cover plate.

[0007] Furthermore, a rectangular groove that mates with the sealing frame is provided on the side of the connecting frame near the controller body, and a sealing plate is sleeved on the inner side of the controller body. One end of the sealing plate extending to the outer side of the controller body is fixed on the inner wall of the sealing cover.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A waterproof controller includes a controller body 1, a connecting frame 4 fixed to one end of the controller body 1, a sealing plate 13 sleeved on the inner side of the controller body 1, the end of the sealing plate 13 extending to the outer side of the controller body 1 and fixed to the inner wall of a sealing cover plate 3, a sealing gasket 2 covering the outer side of the sealing cover plate 3, a sealing gasket 2 fixed to the outer edge of the controller body 1 on the side of the sealing cover plate 3, a sealing clip frame 5 fixed to the side of the sealing cover plate 3 near the inside of the controller body 1, a rectangular groove that mates with the sealing clip frame 5 opened on the side of the connecting frame 4 near the controller body 1, the sealing clip frame 5 engaging and inserting into the inside of the controller body 1, and clamping components symmetrically arranged on each side of the sealing cover plate 3.

[0022] Specifically, when the sealing cover plate 3 needs to be installed, the sealing cover plate 3 is aligned and fitted onto the outside of the connecting frame 4, and the sealing clip frame 5 is inserted into the rectangular groove. At the same time, the sealing plate 13 is inserted into the controller body 1, and the sealing cover plate 3 abuts against the side of the sealing pad 2. After it fits with the sealing pad 2, the connection between the sealing cover plate 3 and the connecting frame 4 is sealed. This multiple sealing ensures the sealing performance of the connection between the controller body 1 and the sealing cover plate 3, and the insertion operation is simple and convenient.

[0023] As an optimization solution, such as Figure 3As shown, the clamping assembly includes a supporting rotating plate 7, a fixing screw 8, and a fixing clamp 9. Each side of the sealing cover plate 3 is symmetrically connected to a rotating connecting rod 6. Each side of the sealing cover plate 3 is symmetrically provided with a rotating groove 12 that cooperates with the rotating connecting rod 6. Each rotating groove 12 is set as a horizontally placed convex shape. The end of the rotating connecting rod 6 extending to the outside of the sealing cover plate 3 is fixed with a supporting rotating plate 7. The fixing screw 8 is threaded inside the supporting rotating plate 7. The side of the fixing screw 8 near the sealing gasket 2 is rotatably connected to a fixing clamp 9 through a bearing for clamping the sealing gasket 2. Each side of the fixing clamp 9 has a fixing slot 10 that cooperates with the fixing clamp 9. Each fixing slot 10 is set as a rectangle that cooperates with the fixing clamp 9. The sealing frame 5 away from the sealing cover plate 3, the side of the sealing gasket 2 near the sealing cover plate 3, and the side of the fixing clamp 9 near the inside of the fixing slot 10 are all glued and fixed with sealing gaskets 11.

[0024] Specifically, when it is necessary to separate the sealing cover plate 3 and the sealing gasket plate 2, tighten the fixing screw 8 so that the fixing screw 8 drives the fixing clamp 9 to move outward, and move the fixing clamp 9 out of the fixing slot 10. At this time, the limitation of the fixing clamp 9 on the supporting rotating plate 7 is released. Rotate the rotating connecting rod 6 to rotate the supporting rotating plate 7 and the fixing clamp 9 to be misaligned with the sealing gasket plate 2. Then pull the sealing cover plate 3 outward to separate the sealing cover plate 3 from the controller body 1. Open the controller body 1. When installing, first cover the sealing cover plate 3 on the connecting frame 4. Rotate the rotating connecting rod 6 so that the fixing clamp 9 is aligned with the fixing slot 10. Then tighten the fixing screw 8 to drive the fixing clamp 9 to abut and press tightly inside the fixing slot 10, and the sealing cover plate 3 can be fixed to the controller body 1.
