DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting on the application or its applications or uses. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present application.

[0039] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0040] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used here to describe the spatial positional relationship of a device or feature as shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device as described in the figure. For example, if a device in the figure is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures.

[0041] See also Figures 1 to 6 As shown, according to an embodiment of the present invention, a motor assembly is provided, which includes a motor body 1, a bracket 2, and a vibration damper 3; mounting holes 201 are respectively provided on the two side walls of the bracket 2; the two end faces of the motor body 1 are respectively mounted on the bracket 2 through the vibration damper 3, and the two end faces of the motor body 1 are respectively provided with connecting ring grooves 101; one end of the vibration damper 3 is installed in the connecting ring groove 101, and the other end of the vibration damper 3 extends in a direction away from the end face of the motor body 1; the vibration damper 3 is engaged in the mounting hole 201 so that the motor body 1 is mounted on the bracket 2.

[0042] Specifically, when installing the motor body 1, align one end of the vibration damper 3 with the connecting ring groove 101 on the end face of the motor body 1, ensuring that the vibration damper 3 is stably installed in the connecting ring groove 101 and that it is securely installed and accurately positioned. Move the motor body 1 with the vibration damper 3 to the vicinity of the bracket 2, so that the two end faces of the motor body 1 are opposite the two side walls of the bracket 2, while ensuring that the other end of the vibration damper 3 is aligned with the mounting hole 201 on the side wall of the bracket 2. After the motor body 1 is roughly aligned with the bracket 2, insert the other end of the vibration damper 3 into the mounting hole 201 on the side wall of the bracket 2.

[0043] In this embodiment, when the motor body 1 is running, vibration and noise will be generated, the damping member 3 is installed between the motor body 1 and the support 2, when the motor vibrates, the damping member 3 can absorb and buffer the vibration energy, reduce the transmission of vibration to the support 2 and the surrounding structure, thereby effectively reducing the noise generated by the whole fan coil motor during operation, improving the noise control performance of the product, making the operation more quiet and stable. During installation, even if there is a certain error in the alignment of the motor body 1 and the support 2, the existence of the damping member 3 can also play a certain adjusting role, its own elastic deformation can make up for part of the assembly error, so that the motor body 1 can be more evenly erected on the support 2, avoiding problems such as motor shaft deflection and unstable rotation caused by assembly eccentricity, ensuring the normal operation and performance of the motor, improving the reliability and consistency of the product. The damping member 3 is installed in the connecting ring groove 101 on the end surface of the motor body 1 and is clamped into the mounting hole 201 in the side wall of the support 2. This structure forms a multi-point uniform support between the motor body 1 and the support 2, compared with the traditional two-side screw fixing method, the stress is more uniform, which can effectively reduce the vibration and swing of the motor body 1 during operation, improve the stability and reliability of the motor operation, reduce the risk of motor damage caused by excessive local stress, and the elastic properties of the damping member 3 can effectively buffer the vibration and impact during motor operation. When the motor is subjected to external vibration or vibration generated by itself, the damping member 3 can absorb and dissipate part of the vibration energy, reducing the transmission of vibration between the motor and the support 2, thereby reducing the impact of vibration on the performance and service life of the motor, improving the reliability and durability of the motor, and reducing the noise and damage caused by vibration.

[0044] In this embodiment, in addition to the damping effect of the damping member 3, the installation method of clamping the damping member 3 in the mounting hole 201 of the support 2 is adopted, compared with the traditional screw fixing method, the operation is more simple and fast, without the need to use tools to tighten the screws, only need to align the damping member 3 with the mounting hole 201 and clamp it in, the connection between the motor and the support 2 can be completed, reducing the assembly difficulty and the requirement for the technical level of the operator, improving the assembly efficiency, at the same time, it can also ensure the consistency and stability of the assembly, reducing the assembly problems caused by improper tightening force and other human factors. This installation method of the damping member 3 makes the connection between the motor body 1 and the support 2 more convenient, when the motor needs to be maintained or replaced, the damping member 3 can be removed from the mounting hole 201 of the support 2, and the motor body 1 can be easily detached from the support 2 without the need to disassemble the screws and other fasteners, greatly simplifying the disassembly process, saving maintenance time and labor cost, at the same time, when installing a new motor body 1, the installation can also be quickly completed, improving the maintenance efficiency of the equipment.

[0045] It is worth mentioning that the motor structure as a whole in the motor body 1 of the embodiment relates to the installation of the motor on the support 2. The motor can be provided with a connecting ring groove 101 at each end of the shell of the motor, or the motor can include two end covers, and the end faces of the two end covers are respectively provided with a damping member 3. In other embodiments, the motor body 1 can be provided with a damping member 3 at the connecting position of the motor body 1 and the support 2. The position of the damping member 3 needs to be considered according to the connecting position of the motor body 1 and the support 2.

[0046] For reference Figures 1 to 6 As shown in the drawings, the motor body 1 includes a front end cover 4, a rear end cover 5, a bearing, and a rotating shaft 6. The rotating shaft 6 is arranged in the front end cover 4 and the rear end cover 5. One end of the front end cover 4 and the rear end cover 5 is connected to each other. The end face of the end of the front end cover 4 away from the rear end cover 5 is provided with a first bearing chamber 401. The end face of the end of the rear end cover 5 away from the front end cover 4 is provided with a second bearing chamber 501. In the axial direction of the rotating shaft 6, the first bearing chamber 401 protrudes from the end face of the front end cover 4. The connecting position of the first bearing chamber 401 and the front end cover 4 is provided with a connecting ring groove 101. The second bearing chamber 501 protrudes from the end face of the rear end cover 5. The connecting position of the second bearing chamber 501 and the rear end cover 5 is provided with a connecting ring groove 101. The connecting ring groove 101 is a groove, that is, the connecting ring groove 101 is concave on the end face of the end cover. One end of the damping member 3 is installed in the connecting ring groove 101. The other end of the damping member 3 extends away from the end face of the end cover. Here, the other end of the damping member 3 can extend to be flush with the end face of the bearing chamber. That is, the damping member 3 wraps the bearing chamber as a whole. Neither the bearing chamber nor the end cover directly contacts the support 2.

[0047] In the embodiment, the motor assembly further includes a rotor assembly 10, a stator assembly 9, and a bearing. In the installation, the stator assembly 9 is pressed into the front end cover 4 by a hydraulic machine. The rotor assembly 10 is installed. The bearing is respectively installed into the first bearing chamber 401 of the front end cover 4 and the second bearing chamber 501 of the rear end cover 5. The rear end cover 5 is installed with the front end cover 4. The power line passes through the motor outlet. The front end cover 4 and the rear end cover 5 are connected together by screws and nuts. The rotating shaft 6 is arranged in the bearing of the front end cover 4 and the rear end cover 5 to ensure smooth rotation of the rotating shaft 6 in the bearing. The damping member 3 is installed at the connecting ring groove 101 of the front end cover 4 and the rear end cover 5. One end of the damping member 3 is aligned with the connecting ring groove 101, and then embedded and ensured to be firmly installed and accurately positioned. The motor body 1 with the damping member 3 is moved to the vicinity of the support 2. The front end cover 4 and the rear end cover 5 of the motor body 1 are respectively opposite to the two side walls of the support 2. The other end of the damping member 3 is aligned with the mounting hole 201 on the side wall of the support 2. Then, the other end of the damping member 3 is clamped into the mounting hole 201 of the side wall of the support 2.

[0048] In this embodiment, the bearing chamber of the front end cover 4 and the rear end cover 5 is combined with the connection ring groove 101, which provides a clear and stable mounting position for the damping member 3. This arrangement enables the damping member 3 to be quickly and accurately mounted on the motor body 1 without the need for additional alignment or positioning operations, greatly improving the convenience and efficiency of assembly. The connection between the damping member 3 and the motor body 1 is more secure and firm due to the connection ring groove 101, and the damping member 3 is firmly embedded in the connection ring groove 101, effectively preventing it from loosening or falling off during motor operation, ensuring reliable connection between the motor and the bracket 2, and improving the overall stability of the motor assembly. The bearing chamber protrudes from the end face of the front end cover 4 and the rear end cover 5, which makes rational use of the axial space of the motor body 1, making the structure of the motor body 1 more compact, while leaving enough space for the installation of the damping member 3 and the bracket 2, which is conducive to the miniaturization and integration of the entire motor assembly. The structure of the front end cover 4 and the rear end cover 5 integrates the bearing chamber and the connection ring groove 101, reducing the number and types of parts and simplifying the structure of the motor body 1. This integrated arrangement not only reduces production costs, but also improves production efficiency, and is also convenient for subsequent maintenance and replacement. In addition, the connection between the end cover surface and the bearing chamber is provided with a connection ring groove 101, which shortens the shaft distance and reduces the deformation amount during motor operation, effectively reducing motor noise.

[0049] As a specific implementation, the front end cover 4 and the rear end cover 5 are stretch-formed integrally, and the end cover surface is integrated with a reinforcing rib to enhance the strength of the end cover, which is conducive to the stable performance of the motor.

[0050] For reference Figures 1 to 7 As shown in the figure, the damping member 3 includes a circular ring body 302 and a boss 303. The circular ring body 302 is a cylinder, and the boss 303 is also a cylinder. One end of the circular ring body 302 is directed towards the end face of the motor body 1 and is provided with the boss 303, i.e. the circular ring body 302 is directed towards the end face of the end cover. The other end of the circular ring body 302 extends away from the end face of the motor body 1. The boss 303 is installed in the connection ring groove 101, and the circular ring body 302 is clamped in the mounting hole 201.

[0051] Specifically, ensure that the boss 303 is directed towards the connection ring groove 101, press the damping member 3 so that the boss 303 is completely embedded in the connection ring groove 101, and make the front end cover 4 and the rear end cover 5 of the motor body 1 respectively opposite to the two side walls of the bracket 2, while ensuring that the circular ring body 302 of the damping member 3 is aligned with the mounting hole 201 on the side wall of the bracket 2. Press the circular ring body 302 of the damping member 3 so that it is completely clamped in the mounting hole 201, ensuring that the damping member 3 is firmly installed and does not loosen.

[0052] In this embodiment, the shape of the boss 303 matches the connecting ring groove 101, which can be accurately embedded in the groove during installation, providing a clear installation position for the damping member 3, ensuring stable and reliable connection with the motor body 1, avoiding displacement or loosening of the damping member 3 during motor operation, maintaining the consistency of the damping effect, the boss 303 embedded in the connecting ring groove 101 increases the contact area and connection strength between the damping member 3 and the motor body 1, making them more closely combined, improving the overall rigidity of the motor assembly, helping to reduce the vibration amplitude of the motor during operation, reducing the risk of component wear and fatigue damage due to vibration, prolonging the service life of the motor. The shape of the circular ring body 302 is adapted to the mounting hole 201 on the side wall of the bracket 2, which can be smoothly clamped into the hole to realize the quick connection of the damping member 3 and the bracket 2, without the need for complex tools and cumbersome operation steps, simplifying the assembly process, improving production efficiency, reducing labor costs, and also facilitating subsequent disassembly and maintenance work. When the circular ring body 302 of the damping member 3 is clamped into the mounting hole 201, its ring structure can evenly transmit the weight and vibration load of the motor body 1 to the bracket 2, avoiding local stress concentration, reducing the risk of deformation or damage of the bracket 2 due to uneven stress, enhancing the structural stability and load-bearing capacity of the entire motor assembly, ensuring the smoothness of the motor during operation.

[0053] In this embodiment, the combination of the boss 303 and the circular ring body 302 forms a structure with hierarchical and functional division for the damping member 3. The boss 303 can tightly fit with the connecting ring groove 101 on the end surface of the motor body 1, providing a stable support point for the motor body 1. The circular ring body 302 extends outwardly to connect with the support 2. This structure makes the connection between the motor body 1 and the support 2 more reasonable and effective, improving the structural stability and compactness of the entire motor assembly. The boss 303 is embedded in the connecting ring groove 101 of the motor body 1, increasing the contact area and connection strength between the damping member 3 and the motor body 1. After the circular ring body 302 is clamped into the mounting hole 201 of the support 2, the load of the motor body 1 is uniformly transmitted to the support 2. The joint action of the two makes the connection between the motor body 1 and the support 2 more secure, capable of bearing greater radial and axial forces, reducing vibration and displacement of the motor during operation. The boss 303 and the circular ring body 302 together form a complete damping system. During motor operation, the boss 303 can reduce the transmission of vibration between the motor body 1 and the damping member 3, and the circular ring body 302 plays a buffering and isolating role between the motor body 1 and the support 2, effectively absorbing and dissipating vibration energy, reducing the vibration amplitude and noise level of the motor, and improving the stability and comfort of the motor operation. In addition, this structure and installation method of the damping member 3 has certain universality and adaptability, which can be adapted to different specifications and models of the motor body 1 and the support 2. Only the size and shape of the boss 303 and the circular ring body 302 need to be adjusted according to actual needs.

[0054] As a specific implementation, the circular ring body 302 is usually made of a material with certain elasticity, which can effectively absorb and buffer the vibration energy generated by the motor during operation, reducing the transmission of vibration to the support 2 and surrounding structures, thereby reducing the noise during motor operation and improving the comfort of the use environment. At the same time, it also protects the support 2 and other related components from damage caused by vibration, improving the reliability and durability of the entire system.

[0055] For reference Figures 1 to 8 As shown, the outer peripheral wall of the damping member 3 is provided with an outer edge ring groove 301, i.e. the outer peripheral wall of the circular ring body 302 is provided with an outer edge ring groove 301, which is clamped in the mounting hole 201. The outer edge ring groove 301 has a certain depth and width, which can be stably clamped in the mounting hole 201.

[0056] In this embodiment, the outer edge ring groove 301 cooperates with the mounting hole 201 to increase the contact area between the damping member 3 and the bracket 2, which helps to more evenly distribute the weight of the motor body 1 and the load generated during operation, reducing local stress concentration, thereby enhancing the stability of the connection between the damping member 3 and the bracket 2. The outer edge ring groove 301 increases the friction and mechanical locking effect between the damping member 3 and the mounting hole 201. During the operation of the motor, even if subjected to vibration and impact, the damping member 3 is not easy to loosen or pull out of the mounting hole 201, ensuring the reliability of the connection between the motor and the bracket 2. The shape and structure of the outer edge ring groove 301 provide additional elastic deformation space for the damping member 3. When the motor generates vibration, the outer edge ring groove 301 can better adapt and buffer these vibrations, making the damping member 3 more effectively absorb and dissipate vibration energy, thereby improving the damping effect. Through the cooperation of the outer edge ring groove 301 and the mounting hole 201, the stress can be more evenly distributed on the damping member 3 and the bracket 2 when the damping member 3 is subjected to vibration load. This helps to reduce the risk of fatigue damage of the damping member 3 and the bracket 2, prolonging their service life. The outer edge ring groove 301 is matched in shape with the mounting hole 201, which can be quickly aligned and clamped into place during installation, ensuring that the damping member 3 is correctly installed in the designated position, improving the accuracy and efficiency of installation. The outer edge ring groove 301 allows the damping member 3 to be tightly embedded in the mounting hole 201, reducing the use of additional fixing components (such as screws, nuts, etc.), thereby optimizing the structural layout of the motor assembly, making the entire system more compact. This setting integrates the fixing function of the damping member 3 into its own structure, eliminating the need for additional connecting parts, reducing the number and complexity of parts, improving production efficiency and reducing potential failure points.

[0057] For reference Figures 1 to 8 As shown in the longitudinal cross-section of the damping member 3, the diameter of the circular ring body 302 is greater than the diameter of the boss 303, and the connection between the circular ring body 302 and the boss 303 forms a stepped surface, which abuts against the end surface of the motor body 1.

[0058] In this embodiment, the stepped surface abuts against the end surface of the motor body 1, preventing excessive movement of the motor body 1 in the axial direction, ensuring the position stability of the motor body 1 on the support 2, avoiding the intensification of vibration or assembly looseness caused by axial displacement. The larger diameter of the circular ring body 302 cooperates with the mounting hole 201 of the support 2, limiting the shaking of the motor body 1 in the radial direction, ensuring the alignment of the central axis of the motor body 1 with the central axis of the support 2, and reducing radial vibration and swing. The stepped surface has a larger contact area with the end surface of the motor body 1, which can more evenly distribute the weight of the motor body 1 and the load generated during operation, improving the stability of the connection. The close abutment of the stepped surface and the end surface of the motor body 1 increases the friction, preventing the damping member 3 from loosening due to vibration during motor operation, ensuring the reliability of the connection. In addition, the stepped surface plays a guiding and positioning role during installation, ensuring accurate installation of the damping member 3 in place, improving installation efficiency, and the close abutment of the stepped surface and the end surface of the motor body 1 reduces the gap between them, preventing external impurities such as dust and moisture from entering the motor, improving the protection performance of the motor.

[0059] For reference Figures 1 to 8 As shown in the figure, the boss 303 is provided with a plurality of protrusions 304 towards the end surface of the connecting ring groove 101, the plurality of protrusions 304 form a T-shaped protrusion 304, and the plurality of protrusions 304 are arranged in the circumferential direction of the end surface of the boss 303. A plurality of positioning holes 111 are arranged in the connecting ring groove 101, and the protrusions 304 are clamped in the positioning holes 111.

[0060] Specifically, ensure that the boss 303 matches the shape and size of the connecting ring groove 101, the T-shaped protrusion 304 on the boss 303 aligns with the positioning hole 111 in the connecting ring groove 101, and the boss 303 of the damping member 3 is completely embedded in the connecting ring groove 101, ensuring that the T-shaped protrusion 304 is clamped into the positioning hole 111. The front end cover 4 and the rear end cover 5 of the motor body 1 are respectively opposite to the two side walls of the support 2, and at the same time, the circular ring body 302 of the damping member 3 is aligned with the mounting hole 201 on the side wall of the support 2, and is completely clamped into the mounting hole 201, ensuring that the damping member 3 is firmly installed and has no looseness.

[0061] In this embodiment, the plurality of protrusions 304 are arranged in the circumferential direction of the end face of the boss 303, corresponding to and clamped in the plurality of positioning holes 111 in the connecting ring groove 101, which enables the vibration damper 3 to be quickly and accurately positioned during installation, ensuring that the connection position of the vibration damper 3 with the motor body 1 is accurate. After the protrusions 304 are clamped into the positioning holes 111, the contact area and friction between the vibration damper 3 and the motor body 1 are increased, making the connection between them more secure and firm, which helps to improve the ability of the vibration damper 3 to resist axial and radial forces, reducing the risk of loosening due to vibration during operation of the motor, and enhancing the overall reliability of the motor assembly. The plurality of protrusions 304 can distribute the weight of the motor body 1 and the load generated during operation to multiple contact points, avoiding the problem of excessive stress caused by concentrating the load on a few points, which helps to reduce local stress concentration and improve the service life of the vibration damper 3 and the motor body 1, reducing the risk of component damage caused by excessive stress. The cooperation of the T-shaped protrusions 304 and the positioning holes 111 forms a multi-point support structure, which optimizes the path of vibration transmission from the motor body 1 to the vibration damper 3. This structure can more effectively absorb and buffer the vibration generated by the motor, reducing the transmission of vibration to the support 2 and the surrounding structure, thereby improving the vibration damping effect of the entire motor assembly and reducing noise and vibration levels. The arrangement of the plurality of protrusions 304 makes the installation of the vibration damper 3 on the end face of the motor body 1 more stable, reducing the vibration and movement of the vibration damper 3 itself, which enables the vibration damper 3 to better perform its vibration damping function, improving the smoothness of the motor operation and reducing the problem of secondary vibration caused by instability of the vibration damper 3. By arranging the plurality of protrusions 304 on the end face of the boss 303, the connection strength and stability between the vibration damper 3 and the motor body 1 can be improved without increasing additional space. This arrangement makes full use of the connecting ring groove 101 space on the end face of the motor body 1, making the structure of the entire motor assembly more compact, which is conducive to the miniaturization and integration of the equipment. By arranging the plurality of protrusions 304 on the end face of the boss 303 and cooperating with the positioning holes 111, the use of other auxiliary fixing components (such as screws, snap rings, etc.) can be reduced or avoided, simplifying the structure of the motor assembly, reducing production costs and assembly complexity, and also reducing potential failure points, improving the reliability and maintainability of the product.

[0062] For reference Figures 1 to 8 As shown, the connection between the protrusion 304 and the boss 303 is provided with a clamping ring groove 305, and the protrusion 304 extends into the motor body 1 through the positioning hole 111 and is clamped in the positioning hole 111.

[0063] Specifically, align the boss 303 of the damping member 3 with the connecting ring groove 101 of the end cover end face, ensure that the protrusion 304 (T-shaped protrusion 304) on the boss 303 is aligned with the positioning hole 111 in the connecting ring groove 101, press down the damping member 3, make the boss 303 completely embedded in the connecting ring groove 101, at the same time ensure that the protrusion 304 passes through the positioning hole 111 and extends into the motor body 1, that is, the protrusion 304 extends into the end cover. Continue to press the damping member 3, make the protrusion 304 completely match with the positioning hole 111, the clamping ring groove 305 is clamped in the positioning hole 111, ensure that the damping member 3 is installed firmly and without looseness.

[0064] In this embodiment, after the protrusion 304 passes through the positioning hole 111 and extends into the motor body 1, it forms a closer match with the internal structure of the motor body 1, effectively preventing the damping member 3 from rotating in the connecting ring groove 101 of the end face of the motor body 1, ensuring the relative static between the damping member 3 and the motor body 1, improving the stability of the motor during operation. After the protrusion 304 extends into the motor body 1, it increases the connection strength between the damping member 3 and the motor body 1, making it more difficult for the damping member 3 to be pulled out of the connecting ring groove 101, enhancing the firmness and reliability of the connection, reducing the risk of looseness caused by vibration. The protrusion 304 extends into the motor body 1, forming a deeper connection structure, further optimizing the path of vibration from the motor body 1 to the damping member 3. This enables the damping member 3 to more effectively absorb and buffer the vibration generated by the motor, reducing the transmission of vibration to the bracket 2 and surrounding structure, thereby improving the damping effect of the entire motor assembly. After the protrusion 304 extends into the motor body 1, it provides more elastic deformation space for the damping member 3, allowing it to better adapt to and buffer the vibration generated during motor operation, further improving the damping effect. The protrusion 304 extends into the motor body 1, making full use of the space inside the motor body 1, making the structure of the entire motor assembly more compact, which is conducive to the miniaturization and integration of the equipment. Through this setting, other auxiliary fixing components (such as screws, clamps, etc.) can be reduced or avoided, simplifying the structure of the motor assembly, reducing production costs and assembly complexity, while also reducing potential failure points, improving product reliability and maintainability.

[0065] In this embodiment, the clamping ring groove 305 is clamped in the positioning hole 111, which increases the friction and mechanical locking effect, preventing the damping member 3 from loosening or falling off due to vibration during motor operation, ensuring the connection reliability between the damping member 3 and the motor body 1. The setting of the clamping ring groove 305 makes it more difficult for the damping member 3 to be pulled out in the axial direction, enhancing the firmness of the connection and ensuring the stability of the damping member 3 during long-term operation. The cooperation of the clamping ring groove 305 and the positioning hole 111 provides a clear installation position for the damping member 3, ensuring its precise alignment with the motor body 1, avoiding problems such as motor eccentricity caused by installation deviation, and improving assembly quality and efficiency.

[0066] Referring to Figures 1 to 8 As shown in the figure, the protrusion 304 is provided with a cross-shaped groove 306 on the end face away from the boss 303, and the cross-shaped groove 306 penetrates the end face of the protrusion 304.

[0067] In this embodiment, the cross-shaped groove 306 weakens the rigidity of the protrusion 304, so that it is easier to produce elastic deformation when subjected to vibration, thereby better absorbing and buffering vibration energy, enhancing the damping effect. The cross-shaped groove 306 is provided to make the protrusion 304 have good elastic deformation capacity in multiple directions, which can effectively deal with vibrations from different directions and improve the damping performance of the damping member 3. During installation, the cross-shaped groove 306 makes the protrusion 304 have a certain elasticity, making it easier to pass through the positioning hole 111 and extend into the motor body 1, reducing the installation difficulty and improving the installation efficiency. Similarly, when disassembling, the elastic setting of the cross-shaped groove 306 makes the protrusion 304 easier to pull out of the positioning hole 111, simplifying the disassembly process and facilitating maintenance and replacement.

[0068] As a specific implementation, the circular ring body 302 and the boss 303 are made of silica gel material, and a through hole is coaxially provided in the middle of the circular ring body 302 and the boss 303. The size of the through hole is consistent with the outer diameter of the bearing chamber of the end cover, ensuring the accuracy of the installation of the end cover.

[0069] Referring to Figures 1 to 12 As shown in the figure, the bracket 2 is cold-rolled steel plate pressure casting, and the upper part is a semicircular structure, that is, the mounting hole 201 is a semicircular structure, and the circular arc angle is in a hand-holding type. The bracket 2 includes a first supporting arm 21 and a second supporting arm 22 arranged opposite to each other, and the first supporting arm 21 and the second supporting arm 22 are respectively provided with mounting holes 201. The mounting hole 201 has a broken section, and the two ends of the broken section are respectively provided with a first clamping hook 202 and a second clamping hook 203. Part of the wall surface of the damping member 3 is installed in the mounting hole 201, the first clamping hook 202 and the second clamping hook 203 are reversely oriented to the damping member 3, and the first clamping hook 202 and the second clamping hook 203 are clamped with the outer edge of the damping member 3.

[0070] Specifically, the front end cover 4 and the rear end cover 5 are connected to form the shell of the motor body 1, then the bearings are respectively installed into the bearing chambers of the front end cover 4 and the rear end cover 5, and finally the shaft 6 is inserted into the bearings, the boss 303 of the damping member 3 is aligned with the connecting ring groove 101 on the end surface of the motor body 1, the protrusion 304 on the boss 303 is aligned with the positioning hole 111 in the connecting ring groove 101, the damping member 3 is pressed down, the boss 303 is completely embedded into the connecting ring groove 101, and the protrusion 304 passes through the positioning hole 111 and extends into the motor body 1. The front end cover 4 and the rear end cover 5 of the motor body 1 are respectively against the two side walls of the bracket 2, and the circular ring body 302 of the damping member 3 is against the mounting hole 201 on the side wall of the bracket 2. The circular ring body 302 of the damping member 3 is pressed inward against the mounting hole 201, and a part of the circular ring body 302 enters the mounting hole 201. The first clamping hook 202 and the second clamping hook 203 are clamped with the outer edge of the damping member 3 to form a tight connection, ensuring that the damping member 3 is firmly installed.

[0071] In this embodiment, the first clamping hook 202 and the second clamping hook 203 are reversely oriented towards the damping member 3 and clamped with the outer edge of the damping member 3 to form a firm clamping structure, preventing the damping member 3 from loosening from the mounting hole 201 during use and ensuring the stability of the connection between the damping member 3 and the bracket 2. Even in the vibration environment during the operation of the motor, the fixation of the damping member 3 can be maintained. The clamping of the clamping hooks with the outer edge of the damping member 3 increases the connection strength between the damping member 3 and the bracket 2, making them more tightly combined and improving the overall rigidity of the motor assembly. This helps to reduce the vibration amplitude of the motor during operation, reduces the risk of wear and fatigue damage of parts caused by vibration, and prolongs the service life of the motor. The arrangement of the clamping hooks enables the damping member 3 to be quickly and accurately clamped into the mounting hole 201 without the need for complex tools and tedious operation steps, simplifying the assembly process, improving production efficiency, reducing labor costs, and facilitating subsequent disassembly and maintenance work. If the damping member 3 needs to be disassembled, the structure of the clamping hooks also makes it relatively easy to disconnect the connection between the damping member 3 and the bracket 2, facilitating maintenance and replacement. The clamping hooks provide a clear installation position for the damping member 3, ensuring accurate alignment of the connection between the damping member 3 and the bracket 2, avoiding problems such as motor eccentricity caused by installation deviation, improving assembly quality and efficiency, and ensuring the performance and reliability of the motor assembly. The clamping of the clamping hooks with the outer edge of the damping member 3 enables the weight and vibration load of the motor body 1 to be evenly transmitted to the bracket 2, avoiding local stress concentration and reducing the risk of deformation or damage of the bracket 2 caused by uneven stress, enhancing the structural stability and load-bearing capacity of the entire motor assembly, and ensuring the smoothness of the motor during operation.

[0072] For reference Figures 1 to 12As shown, the outer edge of the damping member 3 is circumferentially provided with a first self-locking groove 307 and a second self-locking groove 308, and the outer edge of the damping member 3 is circumferentially covered with a reinforcing ring 309, the reinforcing ring 309 is a steel ring, the steel ring is matched with the outer shape of the damping member 3, and the reinforcing ring 309 covers the groove walls of the first self-locking groove 307 and the second self-locking groove 308, that is, the reinforcing ring 309 is an integral structure, and is continuously transitioned even at the self-locking grooves; the first clamping hook 202 is clamped into the first self-locking groove 307, and the second clamping hook 203 is clamped into the second self-locking groove 308. The surface of the steel ring is galvanized and passivated to make it more firm and durable.

[0073] Specifically, the circular ring body 302 of the damping member 3 is aligned with the mounting hole 201 of the side wall of the support 2, at the same time, the first self-locking groove 307 and the second self-locking groove 308 on the outer edge of the damping member 3 are respectively aligned with the first clamping hook 202 and the second clamping hook 203 in the mounting hole 201 of the support 2, and the circular ring body 302 of the damping member 3 is pressed to partially enter the mounting hole 201. During the pressing process, the first clamping hook 202 and the second clamping hook 203 will respectively contact the first self-locking groove 307 and the second self-locking groove 308 covered by the reinforcing ring 309.

[0074] In this embodiment, the reinforcing ring 309 is a steel ring, has high rigidity and strength, and is covered on the outer edge of the damping member 3 in the circumferential direction, which can significantly improve the rigidity of the damping member 3, prevent the damping member 3 from being deformed due to radial force or axial force during use, ensure the shape and size stability of the damping member 3, prolong the service life thereof, cover the groove walls of the first self-locking groove 307 and the second self-locking groove 308, and enhance the structural strength at the self-locking grooves, so that the clamping of the clamping hooks and the self-locking grooves is more firm and reliable, prevents the clamping hooks from being loosened due to the deformation of the groove walls of the self-locking grooves, and improves the overall stability and reliability of the motor assembly. The covering of the reinforcing ring 309 enables the outer edge of the damping member 3 to have appropriate elastic deformation capability when the clamping hooks are clamped into the self-locking grooves, which not only ensures that the clamping hooks can be smoothly clamped into the self-locking grooves, but also provides sufficient clamping force, so that the connection between the damping member 3 and the support 2 is tight and not easy to loosen, the outer shape of the reinforcing ring 309 is matched with the damping member 3, which can ensure the consistency of the circumferential dimension of the outer edge of the damping member 3, thereby improving the precision and consistency of the clamping, and avoiding the problems of loose clamping or deflection caused by irregular shape of the damping member 3.

[0075] As a specific implementation, the outer edge of the circular ring body 302 is provided with a convex groove 310, which can be elastically deformed during assembly with the support 2, and the first clamping hook 202 and the second clamping hook 203 of the support 2 are more easily installed in the corresponding self-locking grooves.

[0076] For reference Figures 1 to 12As shown, the first self-locking groove 307 and the second self-locking groove 308 are both trapezoidal in shape with the cross section of the damping member 3 as the projection plane. The first self-locking groove 307 has a first acute angle A, and the angle A satisfies: 65°≤A≤85°. The second self-locking groove 308 has a second acute angle B, and the angle B satisfies: 55°≤B≤85°. The hook tip angle of the first hook 202 is a, and the angle a satisfies: 60°≤a≤85°. The hook tip angle of the second hook 203 is b, and the angle b satisfies: 30°≤b≤60°.

[0077] In the present embodiment, the first acute angle A of the first self-locking groove 307 is between 65° and 85°, and the hook tip angle a of the first hook 202 is between 60° and 85°. The two angles overlap in the range, which can achieve precise matching, so that the hook and the self-locking groove are tightly connected, ensuring that the damping member 3 will not loosen due to vibration after installation, improving the reliability of the connection. The first self-locking groove 307 and the second self-locking groove 308 are both trapezoidal in shape. Once the hook is inserted, the trapezoidal structure provides lateral support, making it difficult for the damping member 3 to move in the axial and radial directions, thereby enhancing the stability of the connection and preventing the damping member 3 from shifting or rotating during motor operation. The second acute angle B of the second self-locking groove 308 is between 55° and 85°, and the hook tip angle b of the second hook 203 is between 30° and 60°. The appropriate angle setting facilitates the smooth guiding of the hook into the self-locking groove during assembly, reducing the resistance and difficulty during assembly and improving the assembly efficiency. The reasonable angle setting allows the hook to produce appropriate elastic deformation during the connection process, ensuring the tightness of the connection without causing damage to the hook or the self-locking groove due to excessive deformation, making the assembly process smoother and reducing the assembly difficulty and the requirement for assembly tools. The reasonable angle setting allows the stress to be evenly distributed along the angle direction when the hook and the self-locking groove are under stress, avoiding local stress concentration and improving the fatigue life of the connection part, thereby prolonging the service life of the damping member 3 and the bracket 2. The precise angle matching makes the connection between the damping member 3 and the bracket 2 more tight and stable, which can more effectively absorb and dissipate the vibration energy generated during motor operation, reduce the vibration amplitude and noise level of the motor, and improve the vibration reduction effect of the entire motor assembly.

[0078] For reference Figures 1 to 12 As shown, the first arm 21 and the second arm 22 each include a first cantilever 241 and a second cantilever 242. The first cantilever 241 is provided with the first hook 202, and the second cantilever 242 is provided with the second hook 203. The first cantilever 241 and the second cantilever 242 form a mounting hole 201 therebetween. In the horizontal direction, the first cantilever 241 and the second cantilever 242 are inclined to the same side, so as to form an upward converging anti-disengagement structure between the first cantilever 241 and the second cantilever 242.

[0079] In the embodiment, the upward converging anti-extraction structure makes it difficult for the damping member 3 to be extracted from the mounting hole 201 in the vertical direction once it is installed in place. During operation of the motor, even if subjected to vibration and impact force, the damping member 3 can remain stable, ensuring the reliability of the connection between the motor and the support 2. This structure limits the displacement of the damping member 3 in all directions, especially preventing its upward extraction in the vertical direction, enhancing the stability of the overall structure. The provision of the anti-extraction structure allows the stress to be evenly distributed along the inclined cantilever when subjected to load, avoiding stress concentration, enhancing the structural strength of the support 2, prolonging the service life, and the inclined cantilever arrangement makes the entire support 2 structure more compact, optimizing space utilization, while improving the overall strength of the structure.

[0080] As a specific embodiment, the side of the support 2 is taken as the projection plane, and the support 2 is made of cold-rolled steel sheet by die casting. The left side of the support 2 extends to the first arm 21 with a beveled edge, and the included angle between the beveled edge and the bottom of the support 2 in the vertical direction is e, which satisfies: 90°≤e≤180°. The included angle between the beveled edge and the outside of the first arm 21 is c, which satisfies: 90°≤c≤180°. The included angle between the outside of the second arm 22 and the vertical direction of the support 2 is d, which satisfies: 90°≤d≤180°. The arrangement of the included angle e, the included angle c and the included angle d makes the first arm 21 and the second arm 22 in a "hand-holding" manner, ensuring that the motor body 1 can stably bear the weight of the motor when installed horizontally in the load and will not fall off. The width of the support 2 is consistent with the width after the end cover is installed with the damping member 3, ensuring the accuracy of installation.

[0081] For reference Figures 1 to 13 As shown in the drawings, it also includes a capacitor box 7 installed at the bottom of the support 2. The bottom of the support 2 is provided with a buckle 8, and the side wall of the capacitor box 7 facing the buckle 8 is provided with a clamping groove 701, and the buckle 8 is clamped into the clamping groove 701. A limiting groove is also provided at the bottom of the support 2 to limit the capacitor box 7. The two sides and the bottom of the support 2 are provided with reinforcing ribs, one of which is longer and is ≤10mm away from the arc-shaped edge of the upper mounting hole 201, further ensuring the strength of the support 2 and the reliability of the motor during operation.

[0082] In the embodiment, the buckle 8 and the card slot 701 are arranged to enable the capacitor box 7 to be quickly mounted on the bracket 2 without using fasteners such as screws, thereby simplifying the mounting steps and improving the mounting efficiency. Similarly, the structure facilitates the disassembly of the capacitor box 7 and facilitates the maintenance, replacement or upgrading of the capacitor box 7. After the buckle 8 is buckled into the card slot 701, the capacitor box 7 can be tightly fixed to prevent loosening or falling off due to vibration during the operation of the motor, thereby ensuring the connection reliability of the capacitor box 7 and the bracket 2. The limiting groove limits the displacement of the capacitor box 7 in each direction, thereby further enhancing the stability of the capacitor box 7 and ensuring the reliability of the capacitor box 7 in long-term use. The capacitor box 7 is mounted at the bottom of the bracket 2, thereby fully utilizing the vertical space of the motor assembly, making the layout of the entire motor assembly more compact, and being conducive to the miniaturization and integration of the equipment. This arrangement avoids separately arranging a mounting position for the capacitor box 7, reduces the demand of the capacitor box 7 for additional space, and improves the space utilization of the equipment.
