[0042] With the rapid development of new energy vehicles, the electric drive system, as the core power source of new energy vehicles, has also made rapid progress. The multi-functional electric drive technology has gradually matured, and the controller has integrated more modules, which has led to more prominent controller noise issues.

[0043] Currently, reducing controller noise has become an urgent problem to be solved.

[0044] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle according to one or more embodiments of this application.

[0045] Vehicle 1 can be a new energy vehicle, such as a hybrid vehicle or a range-extended vehicle. Vehicle 1 can be a front-wheel drive vehicle, a four-wheel drive vehicle, etc. Vehicle 1 includes an electric drive system 2, which converts electrical energy from the battery into mechanical energy to power vehicle 1 and drive it.

[0046] Reference Figure 2 , Figure 2 This is a first structural schematic diagram of an electric drive assembly according to one or more embodiments of this application.

[0047] To solve the above problems, this application provides an electric drive assembly 2, which includes a controller 10, a motor 20, and an elastic damping part 30. The motor 20 and the controller 10 are spaced apart. The elastic damping part 30 is disposed between the motor 20 and the controller 10, and the elastic damping part 30 is in contact with the controller 10 and the motor 20 respectively. The elastic damping part 30 is configured to deform under the compression of the motor 20 and the controller 10 to limit the relative movement of the controller 10 and the motor 20.

[0048] The motor 20 converts electrical energy from the battery into mechanical energy, thereby generating torque to drive the wheels. The controller 10 converts the direct current from the battery into three-phase alternating current required by the motor 20, and controls the torque and speed of the motor 20, etc. The spaced arrangement between the motor 20 and the controller 10 means that a gap exists between them, and an elastic damping part 30 is located within this gap, contacting both the controller 10 and the motor 20. The elastic damping part 30 is elastic and can be formed of an elastic damping material, which may include, but is not limited to, rubber, asphalt, damping adhesive, etc. It is understood that during the operation of the electric drive assembly 2, the controller 10 will vibrate, including vibrations actively generated by the controller 10 itself and vibrations transmitted to the controller 10 from other components. During vibration, the controller 10 will move relative to the motor 20, thereby compressing the elastic damping part 30 between the controller 10 and the motor 20. The elastic damping part 30 can deform under the compression of the motor 20 and the controller 10, limiting the relative movement between the controller 10 and the motor 20, thereby absorbing and suppressing the vibration of the controller 10 and effectively reducing the vibration noise of the controller 10. It should be noted that the elastic damping part 30 can be set between the motor 20 and the controller 10 in various ways. For example, the elastic damping part 30 can be completely filled in the gap between the motor 20 and the controller 10, or the elastic damping part 30 can be divided into multiple sub-damping parts, which are spaced apart in the gap between the motor 20 and the controller 10.

[0049] Through the above embodiments, the elastic damping part 30 can deform under the compression of the motor 20 and the controller 10, restricting the relative movement of the controller 10 and the motor 20, thereby absorbing the vibration generated by the controller 10, reducing the noise of the controller 10, and at the same time, the structure is simple, the weight is light, and the cost is saved.

[0051] In some embodiments, the controller 10 includes a controller body 11 and a first abutment 12. The first abutment 12 is connected to the controller body 11 and is located on the side of the controller body 11 facing the motor 20. An elastic damping part 30 is located between the first abutment 12 and the motor 20. The first abutment 12 can be used to contact the elastic damping part 30. It is understood that when the controller 10 vibrates and tends to approach the motor 20, the first abutment 12 can abut against and compress the elastic damping part 30 with the motor 20, thereby facilitating full contact between the controller 10 and the motor 20 and the elastic damping part 30, improving the limiting effect of the elastic damping part 30 on the vibration of the controller 10, fully absorbing and suppressing the vibration of the controller 10, thereby reducing the vibration noise of the controller 10. Viewed from the direction from the first abutment 12 to the controller body 11, the shape of the first abutment 12 can be any shape, including but not limited to a circle, a square, or an irregular shape. The first abutment 12 may protrude from the side of the controller body 11 facing the motor 20. The first abutment 12 can be integrally formed with the controller body 11. For example, the boundary of the controller body 11 can be defined by the controller housing, and the first abutment 12 can be integrally formed with the controller housing. The number of first abutment 12 can be one or more, and multiple first abutment 12 can be arranged at intervals. Specifically, the first abutment 12 can be arranged in the area where the controller 10 vibrates more strongly, according to the actual application scenario.

[0052] In some embodiments, the motor 20 includes a motor body 21 and a second abutment 22, which is connected to the motor body 21 and located on the side of the motor body 21 facing the controller 10. An elastic damping portion 30 is located between the second abutment 22 and the controller 10. The second abutment 22 can be used to contact the elastic damping portion 30. It is understood that when the controller 10 vibrates and tends to approach the motor 20, the controller 10 can abut against and compress the elastic damping portion 30 with the second abutment 22, thereby facilitating sufficient contact between the controller 10 and the motor 20 and the elastic damping portion 30, improving the limiting effect of the elastic damping portion 30 on the vibration of the controller 10, and fully absorbing and suppressing the vibration of the controller 10, thereby reducing the vibration noise of the controller 10. Viewed from the direction from the second abutment 22 to the motor body 21, the shape of the second abutment 22 can be any shape, including but not limited to a circle, square, or irregular shape. The second abutment 22 may protrude from the side of the motor body 21 facing the controller 10. The second abutment 22 can be integrally formed with the motor body 21. For example, the boundary of the motor body 21 can be defined by the motor housing, and the second abutment 22 can be integrally formed with the motor housing. The number of second abutment 22 can be one or more, and multiple second abutment 22 can be arranged at intervals. Specifically, the second abutment 22 can be arranged to correspond to the area of ​​the controller 10 where the vibration is relatively strong, according to the actual application scenario.

[0053] In some embodiments, the controller 10 includes a controller body 11 and a first abutment 12. The first abutment 12 is connected to the controller body 11 and is located on the side of the controller body 11 facing the motor 20. The motor 20 includes a motor body 21 and a second abutment 22. The second abutment 22 is connected to the motor body 21 and is located on the side of the motor body 21 facing the controller 10. An elastic damping part 30 is located between the first abutment 12 and the second abutment 22. It is understood that when the controller 10 vibrates and tends to approach the motor 20, the first abutment 12 and the second abutment 22 can abut against and compress the elastic damping part 30, thereby facilitating full contact between the controller 10 and the motor 20 and the elastic damping part 30, and improving the vibration limiting effect of the elastic damping part 30 on the controller 10. The number of the first abutment part 12 and the second abutment part 22 can be set accordingly. For example, the number of the first abutment part 12 and the second abutment part 22 can both be one or both can be multiple. Multiple first abutment parts 12 and multiple second abutment parts 22 can be set one-to-one.

[0054] Combination Figures 6-11 , Figure 6 This is a fifth structural schematic diagram of an electric drive assembly according to one or more embodiments of this application; Figure 7This is a sixth structural schematic diagram of an electric drive assembly according to one or more embodiments of this application; Figure 8 This is a seventh structural schematic diagram of an electric drive assembly according to one or more embodiments of this application; Figure 9 It is based on Figure 8 The diagram shows a cross-sectional view of the electric drive assembly along the AA direction; Figure 10 It is based on Figure 8 The diagram shows a cross-sectional view of the electric drive assembly along the BB direction; Figure 11 It is based on Figure 8 The diagram shows a cross-sectional view of the electric drive assembly along the CC direction.

[0055] In some embodiments, one of the controller 10 and the motor 20 has a recessed receiving groove 40 that is concave compared to the other, and the other has a protrusion 50. The protrusion 50 is inserted into the receiving groove 40 and spaced apart from the inner wall of the receiving groove 40. An elastic damping portion 30 fills the space between the protrusion 50 and the inner wall of the receiving groove 40. Exemplarily, the controller 10 may form the receiving groove 40, and the motor 20 may form the protrusion 50, or the controller 10 may form the protrusion 50, and the motor 20 may form the receiving groove 40. The protrusion 50 is inserted into the receiving groove 40 and spaced apart from the inner wall of the receiving groove 40. The elastic damping portion 30 can fill the space between the protrusion 50 and the receiving groove 40. Exemplarily, the inner wall of the receiving groove 40 may include a side wall and a bottom wall, and the protrusion 50 is spaced apart from the side wall and the bottom wall. Understandably, during vibration, the controller 10 moves relative to the motor 20, causing the protrusion 50 to move relative to the receiving groove 40. The inner walls of the protrusion 50 and the receiving groove 40 compress the elastic damping part 30. The elastic damping part 30 deforms under the compression of the inner walls of the protrusion 50 and the receiving groove 40, thereby limiting the relative movement of the inner walls of the protrusion 50 and the receiving groove 40, thus absorbing and suppressing the vibration of the controller 10, effectively reducing the vibration noise of the controller 10. Therefore, by filling the protrusion 50 and the receiving groove 40 with the elastic damping part 30, the contact area between the controller 10 and the motor 20 and the elastic damping part 30 is increased, improving the vibration absorption and suppression effect of the elastic damping part 30 on the controller 10, and helping the elastic damping part 30 to better reduce the noise of the controller 10. At the same time, the receiving groove 40 and the protrusion 50 cooperate to accommodate the elastic damping part 30, improving the contact stability between the elastic damping part 30 and the controller 10 and the motor 20, reducing the difficulty of setting up the elastic damping part 30, and improving production efficiency.

[0056] In some embodiments, the controller 10 includes a controller body 11 and a first protrusion 13. The first protrusion 13 protrudes from the side of the controller body 11 facing the motor 20. The motor 20 includes a motor body 21 and a second protrusion 23. The second protrusion 23 protrudes from the side of the motor body 21 facing the controller 10. The first protrusion 13 forms a protruding post 50, and the second protrusion 23 forms a receiving groove 40. Understandably, the first protrusion 13 is closer to the motor 20 than the controller body 11, and the second protrusion 23 is closer to the controller 10 than the motor body 21. The distance between the first protrusion 13 and the second protrusion 23 is less than the distance between the controller body 11 and the motor body 21. The first protrusion 13 forms a protrusion 50, and the second protrusion 23 forms a receiving groove 40. The elastic damping part 30 is disposed between the protrusion 50 and the receiving groove 40. This saves the size of the elastic damping part 30 in the distance between the motor body 21 and the controller body 11, reduces the difficulty of setting the elastic damping part 30 and the molding difficulty of the controller 10 and the motor 20, and saves production costs. Optionally, the first protrusion 13 can be integrally formed with the controller body 11, and the second protrusion 23 can be integrally formed with the motor 20. In some other application scenarios, the second protrusion 23 forms a protrusion 50, and the first protrusion 13 forms a receiving groove 40.

[0057] In some embodiments, the electric drive assembly 2 further includes a connecting portion 60, which is fixedly connected to the motor 20 and the controller 10 respectively. The fixed connection between the motor 20 and the controller 10 via the connecting portion 60 improves their relative stability. Optionally, there may be multiple connecting portions 60, which can be arranged along the periphery of the side surface of the controller 10 facing the motor 20. It is understood that the connection points between the motor 20 and the connecting portion 60, and between the controller 10 and the connecting portion 60, are relatively stable. The vibration energy of the controller 10 is mainly concentrated in the position of the controller 10 away from the connecting portion 60. By arranging multiple connecting portions 60 along the periphery of the side surface of the controller 10 facing the motor 20, the elastic damping portion 30 can fully absorb the vibration of the controller 10, thereby reducing the noise of the controller 10.

[0058] In some embodiments, the connecting portion 60 includes a first portion 61 and a second portion 62. The first portion 61 is fixedly connected to the controller 10, and the second portion 62 is fixedly connected to the motor 20. The first portion 61 has a first fixing hole 611, and the second portion 62 has a second fixing hole 621. The first fixing hole 611 and the second fixing hole 621 communicate with each other. The electric drive assembly 2 also includes a fixing member 70, which is inserted into the first fixing hole 611 and the second fixing hole 621 to fix the first portion 61 and the second portion 62. The fixing member 70 can be, but is not limited to, bolts, rivets, etc. By inserting the fixing member 70 into the first fixing hole 611 and the second fixing hole 621, the connection stability of the first portion 61 and the second portion 62 can be effectively improved. In some application scenarios, the first portion 61 and the second portion 62 can also be disassembled by removing the fixing member 70 from the first fixing hole 611 and the second fixing hole 621, thereby improving the flexibility of the first portion 61 and the second portion 62, and thus improving the connection flexibility between the controller 10 and the motor 20. Optionally, the first part 61 and the controller 10 can be separately configured or integrally formed, and the second part 62 and the motor 20 can be separately configured or integrally formed. It should be noted that by configuring the connecting part 60 as a separate first part 61 and second part 62, and connecting the first part 61 and second part 62 by the fastener 70, the difficulty of setting the elastic damping part 30 between the controller 10 and the motor 20 can be reduced, thereby improving production efficiency.

[0059] In some embodiments, the electric drive assembly 2 further includes a reducer 80, which is fixedly connected to the controller 10 and the motor 20. The reducer 80 can reduce the higher speed of the motor 20 to a lower speed usable by the wheels while amplifying torque. The fixed connection of the reducer 80 to the controller 10 and the motor 20 improves the connection stability between the reducer 80 and the controller 10. It is understood that vibrations generated by the reducer 80 can also be transmitted to the controller 10 through the fixed connection with the controller 10 and the motor 20. The elastic damping portion 30 can also absorb at least a portion of the vibrations transmitted from the reducer 80 to the controller 10, thereby reducing the noise of the controller 10. The fixed connection between the reducer 80 and the controller 10 and the motor 20 can be, but is not limited to, detachable and non-detachable connections, wherein detachable connections can include, but are not limited to, bolted connections, etc.

[0061] In some embodiments, at least one of the controller 10 and the motor 20 forms a receiving groove 40 that is recessed relative to the other. The elastic damping portion 30 includes a filling portion 31 and a contact portion 32 connected to each other. The filling portion 31 fills the receiving groove 40, and the contact portion 32 covers the opening of the receiving groove 40. The contact portion 32 contacts the controller 10 and the motor 20 respectively. Exemplarily, the controller 10 may form a receiving groove 40 that is recessed relative to the motor 20, and the position of the motor 20 corresponding to the receiving groove 40 is a relatively flat surface; or the motor 20 may form a receiving groove 40 that is recessed relative to the controller 10, and the position of the controller 10 corresponding to the receiving groove 40 is a relatively flat surface; or the controller 10 forms a receiving groove 40 that is recessed relative to the motor 20, and the motor 20 also forms a receiving groove 40 that is recessed relative to the controller 10. It is understood that the filling part 31 of the elastic damping part 30 fills the receiving groove 40, and the contact part 32 covers the opening of the receiving groove 40. The filling part 31 can fully contact the inner wall of the receiving groove 40, and the contact part 32 can fully contact the outer surface of the controller 10 and the outer surface of the motor 20. This increases the contact area between the elastic damping part 30 and the controller 10 and the motor 20, improves the vibration absorption and suppression effect of the elastic damping part 30 on the controller 10, and helps the elastic damping part 30 to better reduce the noise of the controller 10.

[0062] In some embodiments, the controller 10 has a first recess 41 that is recessed relative to the motor 20, and the motor 20 has a second recess 42 that is recessed relative to the controller 10. The first recess 41 and the second recess 42 are spaced apart from each other. A filling portion 31 fills the first recess 41 and the second recess 42, and a contact portion 32 covers the opening of the first recess 41 and the opening of the second recess 42. Exemplarily, the filling portion 31 may include a first filling segment and a second filling segment spaced apart from each other. The first filling segment fills the first recess 41, the second filling segment fills the second recess 42, and the contact portion 32 is located between the first filling segment and the second filling segment, and covers the opening of the first recess 41 and the second recess 42. It is understandable that the elastic damping part 30 makes full contact with the inner walls of the first groove 41 and the second groove 42 through the filling part 31, and makes full contact with the outer surface of the controller 10 and the outer surface of the motor 20 through the contact part 32. This increases the contact area between the elastic damping part 30 and the controller 10 and the motor 20, improves the vibration absorption and suppression effect of the elastic damping part 30 on the controller 10, and helps the elastic damping part 30 to better reduce the noise of the controller 10.

[0063] In summary, the electric drive assembly 2 provided in this application includes a controller 10, a motor 20, and an elastic damping part 30. The motor 20 and the controller 10 are spaced apart. The elastic damping part 30 is disposed between the motor 20 and the controller 10, and the elastic damping part 30 contacts both the controller 10 and the motor 20. The elastic damping part 30 is configured to deform under the compression of the motor 20 and the controller 10 to limit the relative movement between the controller 10 and the motor 20. Through the above embodiment, the elastic damping part 30 can deform under the compression of the motor 20 and the controller 10, limiting the relative movement between the controller 10 and the motor 20, thereby absorbing the vibration generated by the controller 10, reducing the noise of the controller 10, and at the same time, the structure is simple and cost-effective.
