[0036] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0037] Reference will be made below to Figures 1 - 3 describe the cover plate 1 of the drive assembly according to an embodiment of the present utility model.

[0038] As Figures 1 - 3As shown, the cover plate 1 of the drive assembly according to an embodiment of the present utility model includes: a cover plate main body 10 and a vibration damping member 20. The cover plate main body 10 refers to a panel covering the opening on a machine, device, or a certain system. In this way, the cover plate main body 10 can play a certain sealing role to protect the components inside the device from the external environment. The vibration damping member 20 is a component used to reduce vibration and can be applied to various mechanical equipment to absorb or reduce vibration, thereby protecting the equipment from damage, extending its service life, and helping to reduce noise.

[0039] As Figure 1 and Figure 2 shown, the thickness of the cover plate main body 10 is d, and the value range of d is: 1mm ≤ d ≤ 5mm. The thickness d of the cover plate main body 10 needs to meet a certain range. Specifically, the thickness d of the cover plate main body 10 cannot be too small, that is, less than or equal to 1mm. In this case, the thickness of the cover plate main body 10 is too small to play a sealing role and cannot protect the components inside the device from the external environment. At the same time, the thickness d of the cover plate main body 10 cannot be too large, that is, greater than or equal to 5mm. In this case, although the cover plate main body 10 can play a sealing role and protect the components inside the device from the external environment, the thickness of the cover plate main body 10 will be too large, which is not conducive to the installation of the cover plate main body 10 on the opening of the machine, device, or a certain system. In addition, it will cause an increase in cost and weight, which is not conducive to achieving lightweight and reducing production costs. Therefore, the value range of the thickness d of the cover plate main body 10 is from 1mm to 5mm. Since the overall thickness of the cover plate main body 10 is relatively small and there is no reinforcing rib, a vibration damping member 20 needs to be provided on the cover plate main body 10. In this way, the vibration damping member 20 can protect the equipment from damage, extend its service life, and help to reduce noise.

[0040] The vibration damping member 20 includes: a polymer non-metal layer 200 and a film layer 201. The polymer non-metal layer 200 is connected to the surface of the cover plate main body 10, and the film layer 201 is disposed on the surface of the polymer non-metal layer away from the cover plate main body 10. That is to say, the polymer non-metal layer 200 and the film layer 201 are components of the vibration damping member 20. It should be noted that the polymer non-metal layer 200 can be a polymer damping layer, which can mainly be used to absorb or reduce vibration, thereby protecting the equipment from damage, extending its service life, and helping to reduce noise. The film layer 201 can mainly be used for anti-corrosion.

[0041] Connect the polymer non-metal layer 200 to the surface of the cover plate body 10. The thin film layer 201 is arranged on the surface of the polymer non-metal layer away from the cover plate body 10. The vibration damping member 20 is connected to the surface of the cover plate body 10 through the polymer non-metal layer 200. At this time, the vibration damping member 20 can improve the dynamic stability, vibration isolation, noise reduction and other capabilities of the drive assembly 2. Among them, the thin film layer 201 is a non-aluminum foil thin film layer or an aluminum foil thin film layer. The aluminum foil thin film layer has high structural strength and is not easily damaged. When the thin film layer 201 is a non-aluminum foil thin film layer, at this time, both the polymer non-metal layer 200 and the thin film layer 201 are set as non-metal structures. First of all, compared with the metal structure, the non-metal structure has a lighter mass, which is beneficial to the lightweight design of the vibration damping member 20, and the price of the non-metal structure is lower. In addition, the overall processing and forming of the non-metal structure vibration damping member 20 is simple, the process is less, the assembly difficulty is low, and it also has strong anti-corrosion performance. In this way, the optimized design of the cover plate 1 of the drive assembly can be realized, so as to avoid over-design or design risks of the vibration damping member 20.

[0042] Therefore, by setting the vibration damping member 20 as a combination of the polymer non-metal layer 200 and the thin film layer 201, the dynamic stability, vibration isolation, noise reduction and other capabilities of the drive assembly 2 can be improved. In addition, due to the characteristics of the non-metal structure, at this time, the mass of the vibration damping member 20 is lighter, which is beneficial to the lightweight design, and the manufacturing cost is lower. Moreover, the overall processing and forming of the non-metal structure vibration damping member 20 is simple, the process is less, the assembly difficulty is low, and it also has strong anti-corrosion performance. In this way, the optimized design of the cover plate 1 of the drive assembly can be realized, so as to avoid over-design or design risks of the vibration damping member 20.

[0043] Specifically, as Figure 2 shown, the polymer non-metal layer 200 is a polymer rubber layer, and the thin film layer 201 is a hard plastic thin film layer or an aluminum foil thin film layer. The polymer rubber layer has excellent elasticity, good sealing and corrosion resistance, noise reduction, and easy forming and processing and other advantages. The hard plastic thin film layer and the aluminum foil thin film layer have excellent mechanical strength, good wear resistance and corrosion resistance, good barrier performance and easy processing and forming and other advantages. By setting the polymer non-metal layer 200 as a polymer rubber layer and the thin film layer 201 as a hard plastic thin film layer or an aluminum foil thin film layer, at this time, the polymer non-metal layer 200 and the thin film layer 201 are more in line with the actual working conditions, and the vibration damping member 20 can make full use of the advantages of the two materials. In this way, the overall vibration damping and noise reduction effect of the vibration damping member 20 is good, and the anti-corrosion performance is strong, so as to better meet the actual working conditions.

[0044] Among them, as Figure 1 and Figure 2As shown, the polymer non-metal layer 200 is connected to the inner surface of the cover plate main body 10, or the polymer non-metal layer 200 is connected to the outer surface of the cover plate main body 10. That is to say, the polymer non-metal layer 200 can be arranged on the inner surface or the outer surface of the cover plate main body 10. Of course, when there are multiple polymer non-metal layers 200, a part of them can be arranged on the inner surface of the cover plate main body 10, and the other part can be arranged on the outer surface of the cover plate main body 10, and they can be arranged according to actual needs. At this time, the vibration damping member 20 can better improve the dynamic stability, vibration isolation, noise reduction and other capabilities of the drive assembly 2, so as to protect the drive assembly 2 from damage and extend the service life of the drive assembly 2.

[0045] Optionally, as Figures 1 - 3 , the cover plate main body 10 includes: a flat plate portion and a flanging portion. The flanging portion is connected to the peripheral side of the flat plate portion, and the vibration damping member 20 is connected to the flat plate portion. The flat plate portion and the flanging portion are components of the cover plate main body 10. The flat plate portion is the main body part of the cover plate main body, which can be mainly used to arrange the vibration damping member 20. The flanging portion mainly plays an installation role, and the cover plate main body 10 can be covered on a machine, equipment or a certain system through forms such as bolt fixation. The flanging portion is connected to the peripheral side of the flat plate portion, and the flanging portion is connected to the flat plate portion. At this time, the flat plate portion and the flanging portion form an integral body, which is convenient for the installation and setting of the cover plate main body 10. The vibration damping member 20 is connected to the flat plate portion. At this time, the vibration damping member 20 can protect the equipment from damage, extend the service life, and help reduce noise.

[0046] In addition, as Figure 1 and Figure 3 shown, the area where the vibration damping member 20 is connected to the surface of the flat plate portion is a, and the value range of a is: 0 < a ≤ 800 mm². It should be noted that the area a where the vibration damping member 20 is connected to the surface of the flat plate portion needs to meet a certain range. Specifically, the area a where the vibration damping member 20 is connected to the surface of the flat plate portion needs to be greater than 0, which is in line with the actual situation. The vibration damping member 20 can improve the dynamic stability, vibration isolation, noise reduction and other capabilities of the drive assembly 2, so as to protect the drive assembly 2 from damage and extend the service life of the drive assembly 2. At the same time, the area a where the vibration damping member 20 is connected to the surface of the flat plate portion cannot be too large, that is, greater than 800 mm². In this way, on the premise that the vibration damping member 20 improves the dynamic stability, vibration isolation, noise reduction and other capabilities of the drive assembly 2, the area of the vibration damping member 20 will be too large. At this time, it will cause an increase in cost and weight, which is not conducive to realizing lightweight and reducing production costs. Therefore, the value range of the area a where the vibration damping member 20 is connected to the surface of the flat plate portion is from 0 to 800 mm². Among them, the area where the vibration damping member 20 is connected to the surface of the flat plate portion can be determined through simulation calculation.

[0047] Among them, as Figure 1 and Figure 3As shown, the damping member 20 covers the surface of the flat plate portion. The area where the damping member 20 is connected to the surface of the flat plate portion can be the same as the size of the surface area of the flat plate portion. At this time, the damping member 20 can provide a balanced damping effect, absorb and reduce vibrations, improve the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, thereby protecting the drive assembly 2 from damage, extending the service life of the drive assembly 2, and reducing noise at the same time.

[0048] It should be noted that, as Figure 1 and Figure 3 shown, the surface area of the flat plate portion is s, and the relationship between a and s is: 0.1 ≤ a / s < 1. It should be noted that the ratio between the area a where the damping member 20 is connected to the surface of the flat plate portion and the surface area s of the flat plate portion needs to satisfy a certain range. Specifically, the ratio between a and s cannot be too small, that is, less than or equal to 0.1. In this case, the area a where the damping member 20 is connected to the surface of the flat plate portion will be too small, which is not conducive to the damping member 20 absorbing and reducing vibrations, and cannot improve the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, and may damage the drive assembly 2. At the same time, the ratio between a and s cannot be too large, that is, greater than 1. In this case, on the premise of improving the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, the area a where the damping member 20 is connected to the surface of the flat plate portion will be too large. At this time, some of the damping members 20 will not be able to function, and it will cause an increase in cost and weight, which is not conducive to achieving lightweight and reducing production costs. Therefore, the value range of the ratio between the area a where the damping member 20 is connected to the surface of the flat plate portion and the surface area s of the flat plate portion is from 0.1 to 1. Among them, the ratio between the area where the damping member 20 is connected to the surface of the flat plate portion and the surface area of the flat plate portion can be determined through simulation calculations.

[0049] Optionally, as Figure 1 and Figure 3 shown, the damping member 20 is connected to the middle of the flat plate portion. When the area where the damping member 20 is connected to the surface of the flat plate portion is not the same as the size of the surface area of the flat plate portion, the damping member 20 can be arranged at the center position of the flat plate portion. At this time, the damping member 20 can be evenly distributed and absorb vibrations from all directions, protecting the internal components of the flat plate portion from external vibrations and enhancing the stability and durability of the overall structure. That is to say, the damping member 20 can improve the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, thereby protecting the drive assembly 2 from damage and extending the service life of the drive assembly 2. It should be noted that the position of the damping member 20 can be determined through simulation calculations.

[0050] Specifically, as Figure 1 and Figure 2As shown, the flat part is provided with a mounting groove, and the vibration damping member 20 is arranged in the mounting groove. The mounting groove can play roles such as positioning, fixing, and simplifying the installation process. The flat part is provided with a mounting groove, and the vibration damping member 20 is arranged in the mounting groove. At this time, the vibration damping effect of the vibration damping member 20 can be improved through the precise positioning and fixing of the mounting groove. At the same time, it can ensure that the vibration damping member 20 can be stably installed at the predetermined position, enabling the vibration damping member 20 to achieve an ideal vibration damping effect, thereby protecting the drive assembly 2 from damage and extending the service life of the drive assembly 2.

[0051] Of course, the thickness of the vibration damping member 20 is b, and the value range of b is: 0 < b ≤ 0.5 mm. It should be noted that the thickness b of the vibration damping member 20 needs to meet a certain range. Specifically, the thickness b of the vibration damping member 20 needs to be greater than 0, which is in line with the actual situation. The vibration damping member 20 can improve the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, thereby protecting the drive assembly 2 from damage and extending the service life of the drive assembly 2. At the same time, the thickness b of the vibration damping member 20 cannot be too large, that is, greater than 0.5 mm. In this way, on the premise that the vibration damping member 20 improves the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, the thickness b of the vibration damping member 20 will be too large, which will cause an increase in cost and weight at this time, and is not conducive to achieving lightweight and reducing production costs. Therefore, the value range of the thickness b of the vibration damping member 20 is from 0 to 0.5 mm. Among them, the thickness of the vibration damping member 20 can be determined through simulation calculation.

[0052] Optionally, the relationship between b and d is: b:d = 1:5. The ratio between the thickness b of the vibration damping member 20 and the thickness d of the cover plate body 10 needs to meet a certain value. Specifically, the ratio between b and d can be 1 to 5. At this time, the sealing performance of the cover plate body 10 can be well guaranteed, so that the cover plate body 10 can protect the components inside the device from the influence of the external environment and extend the service life of the device.

[0053] Furthermore, as Figures 1 - 3 shown, the number of the vibration damping members 20 is c, and the value range of c is: 0 < c ≤ 4. It should be noted that the number c of the vibration damping members 20 needs to meet a certain range. Specifically, the number c of the vibration damping members 20 needs to be greater than 0, which is in line with the actual situation. The vibration damping members 20 can improve the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, thereby protecting the drive assembly 2 from damage and extending the service life of the drive assembly 2. At the same time, the number of the vibration damping members 20 cannot be too large, that is, greater than 4. In this way, on the premise that the vibration damping members 20 improve the dynamic stability, vibration isolation, and noise reduction capabilities of the drive assembly 2, the number of the vibration damping members 20 will be too large, which will cause an increase in cost at this time. Therefore, the value range of the number c of the vibration damping members 20 is from 0 to 4. Among them, the number of the vibration damping members 20 can be determined through simulation calculation.

[0054] In addition, as Figure 2 shown, the damping member 20 is provided with a chamfer. At this time, the installation efficiency of the damping member 20 can be improved, the stability and safety of the structure can be enhanced, and the service life can be extended. Specifically, the chamfer can reduce the resistance encountered by the damping member 20 during installation, making it easier to be arranged in the installation groove, which helps to improve the assembly efficiency and reduce the possible damage during installation. Secondly, by setting the chamfer, the stress distribution can be made more uniform, thereby increasing the durability of the damping member 20. In addition, the chamfer can reduce the direct friction and wear between the contact surfaces of the damping member 20 and the cover plate body 10, protect the damping member 20 and the cover plate body 10, and maintain the stability of the drive assembly 2. Among them, the chamfer can be set as a circular chamfer with a radius of about 1 mm.

[0055] In addition to this, as Figure 2 shown, the polymer non-metal layer 200 and the film layer 201 are adhesively connected. Adhesive connection is suitable for connecting different materials. By adopting the adhesive connection method, the connection components can have a uniform stress distribution, good sealing performance, be convenient for reducing weight and reducing vibration and noise. The polymer non-metal layer 200 and the film layer 201 are adhesively connected. At this time, the polymer non-metal layer 200 and the film layer 201 form an integral body, which is convenient for the installation and setting of the damping member 20. In addition, by adopting the adhesive connection method, the overall processing and forming of the damping member 20 is simple, the process is less, the assembly difficulty is low, and the anti-corrosion performance is strong, which is more conducive to realizing lightweight and reducing production costs.

[0056] Specifically, as Figure 1 and Figure 3As shown, the shape of the vibration damping member 20 projected on the cover plate body 10 is a polygon or a circle. That is to say, the shape of the vibration damping member 20 can be set as a polygon or a circle, and can be selected according to specific application requirements, design considerations and manufacturing processes. When the shape of the vibration damping member 20 projected on the cover plate body 10 is a polygon, at this time, the vibration damping performance in certain directions of the vibration damping member 20 can be optimized according to actual needs. Secondly, the polygon design can be customized according to the specific shape of the installation space, and the available space can be maximally utilized. In addition, the mechanical properties of the vibration damping member 20 can be changed by adjusting the number and length of the sides of the vibration damping member 20, so as to adapt to different load conditions and application scenarios. The polygon can be set as a rectangle, etc. When the shape of the vibration damping member 20 projected on the cover plate body 10 is a circle, the circle can provide a relatively uniform stress distribution, reduce local stress concentration, and thus can improve the durability and reliability of the vibration damping member 20. Secondly, the circular design is usually easier to manufacture and process, and standard molds can be used for mass production, thus reducing the manufacturing cost of the vibration damping member 20. In addition, the circular structure has good symmetry. At this time, the vibration damping member 20 can be applied to application occasions that require omnidirectional vibration damping. Therefore, when choosing whether the vibration damping member 20 is a polygon or a circle, comprehensive consideration is needed. First of all, the direction and frequency of the vibration source need to be considered. If the vibration source is multi-directional and random, the circular design is more suitable. If the vibration source has a clear directionality, the polygon design can provide a more targeted vibration damping effect. Secondly, the limitation of the installation space needs to be considered. In the case of limited space, the polygon design can better adapt to complex geometric shapes and maximize the use of available space. In addition, the manufacturing cost and process complexity need to be considered. The circular design is usually easier to manufacture and process and is suitable for mass production, while the polygon design requires more complex molds and processes, but can provide a higher degree of customization.

[0057] It should be noted that as Figure 3 shown, the cover plate 1 is the controller cover plate 30, the power module cover plate (not shown in the figure) and the motor end cover 40. It should be noted that the controller cover plate 30, the power module cover plate and the motor end cover 40 can all effectively protect the internal components, extend the service life of the equipment, and improve the reliability and performance of the overall system. The controller cover plate 30 can prevent dust, moisture and other pollutants from entering the controller, ensuring that the controller can operate stably for a long time. The power module cover plate can protect the power module from physical damage and environmental impacts. The motor end cover 40 can protect key components such as the internal winding and bearing from the external environment. At the same time, the motor end cover 40 also plays a role in supporting the rotor shaft, ensuring the smooth operation of the motor.

[0058] According to the drive assembly 2 of the embodiment of the present invention, it includes: the cover plate 1 of the drive assembly described in the above embodiment.

[0059] In addition, asFigure 3 As shown, the drive assembly 2 further includes: a controller, a power module, and a motor, and at least one of the controller, the power module, and the motor is provided with a cover plate 1.

[0060] Specifically, the controller is composed of a controller housing, a controller cover plate 30, and electronic components. The electronic components are arranged inside the controller housing. The controller housing is provided with an opening, and the controller cover plate 30 is arranged at the opening. The damping member 20 is connected to the controller cover plate 30. At this time, the damping member 20 can absorb and isolate vibrations, protect the sensitive electronic components inside the controller housing from external vibrations, improve the stability and reliability of the controller, and thus extend the service life of the controller.

[0061] The power module is composed of a power housing, a power module cover plate, and battery cells. The battery cells are arranged inside the power housing. The power housing is provided with an opening, and the power module cover plate is arranged at the opening. The damping member 20 is connected to the power module cover plate. At this time, the damping member 20 can absorb and isolate vibrations, protect the power module and the battery cells inside the power housing from external vibrations, and thus significantly improve the reliability and service life of the power module.

[0062] The motor is composed of a motor housing, a motor end cover 40, a stator, and a rotor. The stator and the rotor are generally arranged inside the motor housing. The motor housing is provided with an opening, and the motor end cover 40 is arranged at the opening. The damping member 20 is connected to the motor end cover 40. At this time, the damping member 20 can absorb and isolate vibrations, protect components such as the stator and the rotor inside the motor housing from external vibrations, and improve the stability and reliability of the entire system, and thus extend the service life of the motor.

[0063] It should be noted that, as Figure 3 shown, the power module and the motor are electrically connected to the controller respectively. The power module is electrically connected to the controller. The power module can provide power for the controller to ensure its normal operation. The controller is connected to the motor. The controller can generate corresponding drive signals according to the received instructions or sensor feedback to control the speed and direction of the motor. At the same time, the motor can feedback its operating state to the controller, thereby realizing closed-loop control. The power module realizes energy transfer with the motor through the controller. The controller, the battery module, and the motor can work efficiently in coordination, and thus can ensure the stable operation and long life of the entire system.
