[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4This utility model discloses a rainproof controller for an electric vehicle motor, comprising: a sealed controller 1 and auxiliary components. The front surface of the sealed controller 1 has an abutment groove 8, which provides an installation position for an elastic sealing strip 9 and an abutment block 11, thus forming the first waterproof barrier. The inner surface of the abutment groove 8 abuts against the elastic sealing strip 9, which, through its elastic deformation, tightly adheres to the inner surface of the abutment groove 8, effectively preventing rainwater from entering through gaps in the front surface of the sealed controller 1. The inner surface of the abutment groove 8 abuts against the abutment block 11, which fits tightly with the abutment groove 8, further enhancing the sealing effect and providing a supporting connection base for the sealing block 4. The front surface of the abutment block 11 is fixedly connected to the sealing block 4, which, through its connection with the abutment block 11, securely mounts the entire sealing structure on the front surface of the sealed controller 1, while also providing an installation platform for subsequent components. The four corners of the front surface of the sealing block 4 are threaded with positioning bolts 5, which are used to firmly secure the sealing block 4. Fixed to the sealed controller 1, ensuring the stability of the sealing structure, the outer surface of the positioning bolt 5 is threaded with a nut. The nut works in conjunction with the positioning bolt 5. By tightening the nut, the sealing block 4 is tightly fitted to the sealed controller 1, ensuring the sealing effect. The side wall of the nut abuts against the waterproof sealing block 10, which fills the gap between the nut and the sealed controller 1, preventing rainwater from seeping in from the nut connection and enhancing the waterproof performance. The front surface of the waterproof sealing block 10 and the sealed controller 1 are tightly fitted together, further enhancing the integrity of the waterproof seal. The left and right sides of the front surface of the sealing block 4 are fixedly connected with wire harness threaded posts 6. The wire harness threaded posts 6 are used to connect external wire harnesses and, by cooperating with the waterproof inlet nut 7, ensure the waterproof effect at the wire harness connection. The outer surface of the wire harness threaded post 6 is threaded with a waterproof inlet nut 7. The waterproof inlet nut 7 is tightened onto the wire harness threaded post 6 to seal the wire harness that passes through, preventing rainwater from entering the controller's interior along the wire harness.

[0026] The interior of the contact groove 8 is connected to the outer surface of the sealing controller 1. This connection design allows the elastic sealing strip 9 and the contact block 11 to directly seal and protect the outer surface of the sealing controller 1. The inner surface of the contact block 11 abuts against the elastic sealing strip 9, and the contact block 11 presses the elastic sealing strip 9 inward to make it fill the gap more tightly and improve the waterproof capability. The nut is located inside the sealing block 4. This design allows the nut to be hidden inside the sealing block 4, which ensures the compactness of the structure and provides effective protection through the waterproof sealing block 10. The size of the contact block 11 is adapted to the size of the contact groove 8 to ensure that the contact block 11 can be tightly embedded in the contact groove. Groove 8 ensures a good seal. The size of the waterproof sealing block 10 matches the size of the sealing controller 1, allowing the waterproof sealing block 10 to completely cover the connection between the nut and the sealing controller 1, achieving a good waterproof seal. The number of nuts corresponds to the number of positioning bolts 5, ensuring that the sealing block 4 is evenly stressed and more securely fixed. The interior of the wire harness threaded post 6 is connected to the interior of the sealing block 4, facilitating the wire harness to pass through the sealing block 4 and ensuring the rationality of the internal wiring layout. The interior of the wire harness threaded post 6 is also connected to the interior of the waterproof inlet nut 7, ensuring that the waterproof inlet nut 7 can effectively seal the wire harness and prevent rainwater intrusion. The auxiliary components are located on the outer surface of the sealed controller 1. These components provide additional functional and structural support to ensure stable operation. The auxiliary components include heat dissipation fins 2 and positioning posts 3. The heat dissipation fins 2 and positioning posts 3 respectively handle heat dissipation and positioning functions, improving the performance of the sealed controller 1. Several heat dissipation fins 2 are fixedly connected to the upper and lower surfaces of the sealed controller 1. The heat dissipation fins 2 increase the heat dissipation area of ​​the sealed controller 1, dissipating the heat generated during operation and preventing overheating. Four positioning posts 3 are provided on both the left and right sides of the sealed controller 1. The positioning posts 3 are used to position the sealed controller 1 during installation. To ensure accurate installation and easy integration with other components, the heat dissipation fins 2 are evenly distributed on the outer surface of the sealed controller 1, allowing heat to be dissipated evenly and improving heat dissipation efficiency. The four positioning posts 3 are symmetrically arranged on the upper and lower sides of the side wall of the sealed controller 1 to ensure that the sealed controller 1 is balanced under force during installation and is more stable. The heat dissipation fins 2 are located on the rear surface of the sealing block 4, ensuring that the sealing block 4 works normally without affecting the heat dissipation function of the heat dissipation fins 2. The positioning posts 3 and the waterproof inlet nut 7 are arranged in parallel, so that the components of the controller are reasonably arranged and do not interfere with each other during installation and use, ensuring the stability and waterproof performance of the overall structure.

[0027] Working principle: First, the elastic sealing strip 9 is embedded into the contact groove 8 on the front surface of the airtight controller 1, using its elastic deformation characteristics to initially fill the gap and build a waterproof foundation. Next, the contact block 11 is placed into the contact groove 8, making tight contact with the elastic sealing strip 9 to further enhance the sealing effect and provide support for subsequent components. The sealing block 4 is fixed on the front surface of the contact block 11, so that the wire harness threaded post 6 and the positioning bolt 5 on the front surface of the sealing block 4 are in corresponding positions. By screwing a nut on the outer surface of the positioning bolt 5, the sealing block 4 is firmly fixed to the airtight controller 1. Tightening the nut makes the sealing block 4 fit tightly with the airtight controller 1. At the same time, a waterproof sealing block 10 is installed on the side wall of the nut to fill the gap between the nut and the airtight controller 1, enhancing the waterproof performance. The external wire harness is passed through the wire harness threaded post 6 and the connection inside the sealing block 4. After opening the channel, the waterproof inlet nut 7 is then tightened onto the outer surface of the wire harness threaded post 6 to seal the wire harness and prevent rainwater from entering the controller. When installing the sealed controller 1, the positioning posts 3 symmetrically arranged on its left and right sides are used for positioning to ensure accurate installation and facilitate cooperation with other components. At the same time, since the positioning posts 3 and the waterproof inlet nut 7 are arranged parallel to each other, it can be ensured that the layout of each component is reasonable and does not interfere with each other. After installation, during operation, the heat dissipation fins 2 evenly distributed on the upper and lower surfaces of the sealed controller 1 will increase the heat dissipation area and dissipate the generated heat in time, ensuring stable operation of the controller. In rainy environments, the elastic sealing strip 9, the contact block 11, the waterproof sealing block 10, and the waterproof inlet nut 7 work together to effectively prevent rainwater from entering and protect the internal circuit safety of the controller.
