Description

Technical Field

[0001] This utility model relates to the field of motor cover technology, specifically to a sensor integrated cover for motors and electric drive systems. Background Technology

[0002] The motor controller mainly consists of a control board, on which all functional modules are integrated. The control board is installed inside a housing. However, during motor operation, the internal temperature rises significantly, causing the temperature near the control board to increase. This forces the controller to operate in a high-temperature environment, compromising the board's optimal operating condition. Therefore, a sensor integration cover plate for the motor and electric drive system was designed, integrating the electric drive system onto the cover plate. This improves the circuit board's operating conditions and provides protection. Utility Model Content

[0003] The purpose of this utility model is to provide a sensor integrated cover plate for motors and electric drive systems. An inner ring plate is formed on the cover plate body, and a circuit board and a sealing plate are embedded in the inner ring plate for mounting and positioning of the circuit board and the sealing plate. At the same time, the sealing plate installs the circuit board in the cover plate body, so that the circuit board is integrated in the cover plate body, thereby improving the operating environment of the circuit board.

[0004] This utility model provides the following technical solution: a sensor integrated cover plate for motors and electric drive systems, comprising a cover plate body, wherein a connecting hole is provided on the edge of the cover plate body, characterized in that: an outer ring plate is formed on the edge of the cover plate body, a groove is formed between the outer ring plate and the inner wall of the cover plate body, the outer ring plate is formed on the cover plate body, a central ring is formed at the center of the cover plate body, and an inner ring plate is also formed on the cover plate body, the inner ring plate is located outside the central ring, a circuit board and a sealing plate are sleeved on the central ring, the circuit board is embedded in the inner ring plate, the sealing plate is also embedded in the inner ring plate, the sealing plate is located above the circuit board, and the outer edge of the sealing plate is in contact with the inner wall of the inner ring plate.

[0005] Furthermore, a pad is formed at one end of the inner ring plate, and a boss is formed on the pad. The boss supports the circuit board, ensuring the installation height of the circuit board and preventing the chips and components on the circuit board from touching the pad, thus protecting the components on the circuit board.

[0006] Furthermore, a support boss is formed on the cover plate body. The support boss is located between the pad block and the central ring. The support boss also supports the circuit board and protects the components on the circuit board.

[0007] Furthermore, a positioning post is formed inside the inner ring plate. The positioning post is formed on the cover plate body. The height of the positioning post is higher than the height of the boss. The positioning post supports the sealing plate. The sealing plate is attached to the back of the circuit board. The positioning post limits the installation height of the sealing plate and reduces the pressure of the sealing plate on the back of the circuit board.

[0008] Furthermore, the sealing plate is a shell with one side concave inward, and both the sealing plate and the circuit board have a circular hole in the center. The circular hole is used to fit onto the central ring, and the sealing plate and the circuit board are positioned by the circular hole, which improves the installation efficiency.

[0009] Furthermore, two positioning rings are formed on the bottom surface of the cover plate body. The positioning rings are used to position the opening and to open the oil inlet or outlet of the cooling oil passage. By opening the oil inlet or outlet through the positioning rings, the cooling oil passage in the motor is connected, and cooling oil is introduced to cool the motor.

[0010] Furthermore, the bottom surface of the cover plate body is formed with reinforcing ribs, which include vertical ribs and annular ribs. The vertical ribs are distributed radially with the central ring as the center, and the annular ribs are distributed parallel to the edge of the cover plate body. The rigidity of the cover plate body is enhanced by the vertical ribs and annular ribs.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] (1) By forming an inner ring plate on the cover plate body, the circuit board and the sealing plate are embedded in the inner ring plate, which can be used to position the circuit board and the sealing plate. At the same time, the sealing plate installs the circuit board in the cover plate body, so that the circuit board is integrated in the cover plate body, which improves the working environment of the circuit board.

[0013] (2) By forming a positioning ring between the inner ring plate and the outer ring plate, and using the positioning ring to open the oil inlet and outlet holes, the cover plate body and the cooling oil circuit are connected, which facilitates the cooling oil circuit to pass through the cover plate body, while enhancing the heat dissipation capacity of the cover plate body and further dissipating heat from the circuit board.

[0019] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a sensor integrated cover plate for motors and electric drive systems, including a cover plate body 1. A connecting hole 11 is provided on the edge of the cover plate body 1 for fixing the cover plate to the motor. An outer ring plate 3 is formed on the edge of the cover plate body 1. A groove 2 is formed between the outer ring plate 3 and the inner wall of the cover plate body 1, and a sealing strip is embedded in the groove 2 to maintain a seal between the cover plate body 1 and the motor. The inner sides of the outer ring plate 3 are all recessed downwards. A central ring 44 is formed at the center of the cover plate body 1, and an inner ring plate 4 is provided on the outer side of the central ring 44. The inner ring plate 4 is formed on the cover plate body 1. A circuit board 7 and a sealing plate 8 are sleeved on the central ring 44, with the sealing plate 8 located on the circuit board 7. Above, the central ring 44 positions the circuit board 7 and the cover plate 8, improving the installation efficiency of the circuit board 7 and the cover plate 8. The circuit board 7 is embedded in the inner ring plate 4, and the cover plate 8 is also embedded in the inner ring plate 4, with the outer edge of the cover plate 8 fitting against the inner wall of the inner ring plate 4. By applying glue between the cover plate 8 and the central ring 44 and between the cover plate 8 and the inner ring plate 4, the sealing between the cover plate 8 and the cover plate body 1 is ensured, so that the circuit board 7 and the cover plate body 1 are integrated together, improving the installation efficiency of the circuit board 7. At the same time, the cover plate 8 can increase the contact area with the circuit board 7, improve the heat dissipation of the circuit board 7, and ensure the stable operation of the components. The circuit board 7 is integrated into the cover plate body 1, improving the working environment of the circuit board 7.

[0020] like Figure 2 As shown, a pad 43 is formed at one end of the inner ring plate 4, and a boss 431 is formed on the pad 43. The boss 431 supports and limits the circuit board 7 to prevent the components on the circuit board 7 from colliding with the pad 43.

[0021] A support boss 42 is formed on the cover plate body 1. The support boss 42 is located between the pad block 43 and the central ring 44. The support boss 42 further positions the installation height of the circuit board 7.

[0022] The inner ring plate 4 also has a positioning post 45 formed inside. The positioning post 45 is formed on the cover plate body 1. The height of the positioning post 45 is higher than the height of the boss 431. The positioning post 45 supports the sealing plate 8. The sealing plate 8 is attached to the back of the circuit board 7. At the same time, the setting of the positioning post 45 reduces the pressure of the sealing plate 8 on the circuit board 7 and protects the circuit board 7.

[0023] The sealing plate 8 is a shell with one side recessed inward. The sealing plate 8 is fitted onto the circuit board 7 to position the circuit board 7. Both the sealing plate 8 and the circuit board 7 have a circular hole in the center, which is used to fit onto the central ring 44.

[0024] Two positioning rings 5 ​​are formed on the bottom surface of the cover plate body 1. The positioning rings 5 ​​are used to position the opening. The positioning rings 5 ​​are used to open the oil inlet or outlet of the cooling oil passage, so that the two ends of the cooling oil passage in the motor are connected to the positioning rings 5, which facilitates the injection of cooling oil into the motor.

[0025] The bottom surface of the cover plate body 1 is formed with reinforcing ribs 6. The reinforcing ribs 6 include vertical ribs 61 and annular ribs 62. The vertical ribs 61 are distributed radially with the central ring 44 as the center. The annular ribs 62 are distributed parallel to the edge of the cover plate body 1. The reinforcing ribs 6 further enhance the rigidity and strength of the cover plate body 1.
