DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0024] For ease of description, spatially relative terms such as "on," "above," "on the upper surface of," and "upper" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in a drawing is inverted, a device described as "above" or "on top of" the other devices or features would then be positioned "below" or "beneath" the other devices or features.

[0025] See also Figures 1 to 6As 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 mounted 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, and the vibration damper 3 is clamped in the mounting hole 201 so that the motor body 1 is mounted on the bracket 2.

[0026] 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, ensuring that it is firmly installed and accurately positioned. Move the motor body 1 with the vibration damper 3 near the bracket 2, so that the two end faces of the motor body 1 are respectively opposite the two side walls of the bracket 2, and ensure that the other end of the vibration damper 3 is aligned with the mounting hole 201 on the side wall of the bracket 2. When the motor body 1 and the bracket 2 are roughly aligned, snap the other end of the vibration damper 3 into the mounting hole 201 on the side wall of the bracket 2.

[0027] In this embodiment, when the motor body 1 is running, vibration and noise are generated. The vibration damper 3 is installed between the motor body 1 and the bracket 2. When the motor vibrates, the vibration damper 3 can absorb and buffer the vibration energy, reducing the transmission of vibration to the bracket 2 and the surrounding structure, thereby effectively reducing the noise generated by the entire fan coil motor when it is working, improving the noise control performance of the product, and making it run more quietly and smoothly. During the installation process, even if there is a certain error in the alignment of the motor body 1 and the bracket 2, the presence of the vibration damper 3 can also play a certain regulatory role. Its own elastic deformation can compensate for some of the assembly error, allowing the motor body 1 to be more evenly mounted on the bracket 2, avoiding problems such as motor shaft deflection and unstable rotation caused by assembly eccentricity, ensuring the normal operation and performance of the motor, and improving the reliability and consistency of the product. The vibration damper 3 is installed in the connecting ring groove 101 on the end face of the motor body 1 and is inserted into the mounting hole 201 on the side wall of the bracket 2. This structure forms a multi-point uniform support between the motor body 1 and the bracket 2. Compared with the traditional two-side screw fixing method, the force 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, and reduce the risk of motor damage caused by excessive local force. The elastic properties of the vibration damper 3 itself enable it to play a good buffering role against vibration and impact during the operation of the motor. When the motor is subjected to external vibration or vibration generated by its own operation, the vibration damper 3 can absorb and dissipate part of the vibration energy, reduce the transmission of vibration between the motor and the bracket 2, thereby reducing the impact of vibration on the performance and life of the motor, improving the reliability and durability of the motor, and reducing the noise and damage caused by vibration to the motor.

[0028] In this embodiment, in addition to providing a vibration-damping effect, the vibration damper 3 is also mounted in the mounting hole 201 of the bracket 2. This installation method, in which the vibration damper 3 is snapped into place in the mounting hole 201 of the bracket 2, is simpler and faster to operate than conventional screw fixing methods. No tools are required to tighten the screws; the motor and bracket 2 can be connected by simply aligning the vibration damper 3 with the mounting hole 201 and snapping it into place. This reduces assembly difficulty and the technical requirements for the operator, improving assembly efficiency. It also ensures assembly consistency and stability, reducing assembly problems caused by human factors such as improper tightening force. This installation method of the vibration damper 3 makes the connection between the motor body 1 and the bracket 2 more convenient. When the motor needs to be maintained or replaced, the vibration damper 3 can be simply removed from the mounting hole 201 of the bracket 2 to conveniently remove the motor body 1 from the bracket 2. There is no need to remove fasteners such as screws, greatly simplifying the disassembly process and saving maintenance time and labor costs. Similarly, when installing a new motor body 1, installation can be completed quickly, improving equipment maintenance efficiency.

[0029] It is worth noting that in the present embodiment, the motor body 1 is a whole motor structure, which involves installing the motor on the bracket 2. Connecting ring grooves 101 can be respectively provided at both ends of the motor casing, or the motor can include two end covers, and the end faces of the two end covers are respectively provided with vibration dampers 3. In other embodiments, the vibration damper 3 can also be provided at the connection between the motor body 1 and the bracket 2. The setting position of the vibration damper 3 needs to take into account the connection position of the motor body 1 and the bracket 2.

[0030] See also Figures 1 to 6 As shown, the motor body 1 includes a front end cover 4, a rear end cover 5, a bearing and a rotating shaft 6, and 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 are connected to each other, and the end surface of the front end cover 4 away from the rear end cover 5 is provided with a first bearing chamber 401, and the end surface 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 surface of the front end cover 4, and a connecting ring groove 101 is provided at the connection between the first bearing chamber 401 and the front end cover 4, and the second bearing chamber 501 is provided at the end surface of the rear end cover 5 away from the front end cover 4. The bearing chamber 501 protrudes from the end face of the rear end cover 5. A connecting ring groove 101 is provided at the connection between the second bearing chamber 501 and the rear end cover 5. The connecting ring groove 101 is a groove, that is, the connecting ring groove 101 is recessed on the end face of the end cover. One end of the shock absorber 3 is installed in the connecting ring groove 101, and the other end of the shock absorber 3 extends in a direction away from the end face of the end cover. Here, the other end of the shock absorber 3 extends until it is flush with the end face of the bearing chamber, that is, the shock absorber 3 as a whole wraps the bearing chamber, and the bearing chamber and the end cover are not in direct contact with the bracket 2.

[0031] In this embodiment, the motor assembly also includes a rotor assembly 10, a stator assembly 9 and bearings. During installation, the stator assembly 9 is pressed into the front end cover 4 using a hydraulic press, the rotor assembly 10 is installed, and the bearings are respectively installed in 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 cord is passed through the motor outlet, and the front end cover 4 and the rear end cover 5 are connected together using screws and nuts. The rotating shaft 6 is inserted into the bearings of the front end cover 4 and the rear end cover 5 to ensure that the rotating shaft 6 rotates smoothly in the bearings. Install the vibration damper 3 at the connecting ring groove 101 of the front end cover 4 and the rear end cover 5 respectively, align one end of the vibration damper 3 with the connecting ring groove 101, then embed it and ensure that it is firmly installed and positioned accurately, move the motor body 1 with the vibration damper 3 to the vicinity of the bracket 2, so that 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 bracket 2, ensure that the other end of the vibration damper 3 is aligned with the mounting hole 201 on the side wall of the bracket 2, and then snap the other end of the vibration damper 3 into the mounting hole 201 on the side wall of the bracket 2.

[0032] In this embodiment, the bearing chambers of the front end cover 4 and the rear end cover 5 are combined with the connecting ring groove 101 to provide a clear and stable installation position for the vibration damper 3. This arrangement enables the vibration damper 3 to be quickly and accurately installed on the motor body 1 without the need for additional alignment or positioning operations, greatly improving the convenience and efficiency of assembly. The setting of the connecting ring groove 101 makes the connection between the vibration damper 3 and the motor body 1 tighter and stronger. The vibration damper 3 is firmly embedded in the connecting ring groove 101, which can effectively prevent it from loosening or falling off during the operation of the motor, ensuring a 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 faces of the front end cover 4 and the rear end cover 5. This arrangement rationally utilizes the axial space of the motor body 1, making the structure of the motor body 1 more compact. At the same time, it leaves enough space for the installation of the vibration damper 3 and the bracket 2, which is conducive to the miniaturization and integration of the entire motor assembly. The structural arrangement of the front end cover 4 and the rear end cover 5 integrates the bearing chamber and the connecting ring groove 101 together, 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, while also facilitating subsequent maintenance and replacement. In addition, a connecting ring groove 101 is provided at the connection between the end cover surface and the bearing chamber. The connecting ring groove 101 shortens the axis spacing, reduces the deformation during motor operation, and effectively reduces motor noise.

[0033] As a specific implementation method, the front end cover 4 and the rear end cover 5 are formed in one piece by stretching, and reinforcing ribs are integrated on the surface of the end covers to enhance the strength of the end covers, which is beneficial to the stability of the motor performance.

[0034] See also Figures 1 to 7As shown, the vibration damper 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 faces the end face of the motor body 1 and is provided with the boss 303, that is, the circular ring body 302 faces the end face of the end cover, and the other end of the circular ring body 302 extends in a direction away from the end face of the motor body 1; the boss 303 is installed in the connecting ring groove 101, and the circular ring body 302 is clamped in the mounting hole 201.

[0035] Specifically, ensure that the boss 303 is facing the connecting ring groove 101, press the vibration damper 3 so that the boss 303 is completely embedded in the connecting ring groove 101, and make the front end cover 4 and the rear end cover 5 of the motor body 1 face the two side walls of the bracket 2 respectively. At the same time, ensure that the circular ring body 302 of the vibration damper 3 is aligned with the mounting hole 201 on the side wall of the bracket 2, press the circular ring body 302 of the vibration damper 3 so that it is completely stuck in the mounting hole 201, and ensure that the vibration damper 3 is firmly installed and not loose.

[0036] In this embodiment, the shape of the boss 303 matches the connecting ring groove 101 and can be accurately embedded in the groove during installation, providing a clear installation position for the vibration damper 3, ensuring its stable and reliable connection with the motor body 1, avoiding displacement or loosening of the vibration damper 3 during the operation of the motor, and maintaining the consistency of the vibration damping effect. The boss 303 embedded in the connecting ring groove 101 increases the contact area and connection strength between the vibration damper 3 and the motor body 1, making the two 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, and extending 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, and can be smoothly inserted into the hole to achieve quick connection between the vibration damper 3 and the bracket 2. No complicated tools and tedious operating steps are required, which simplifies the assembly process, improves production efficiency, reduces labor costs, and is also beneficial to subsequent disassembly and maintenance work. When the circular ring body 302 of the vibration damper 3 is inserted into the mounting hole 201, its annular structure can evenly transfer 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 caused by uneven force on the bracket 2, enhancing the structural stability and load-bearing capacity of the entire motor assembly, and ensuring the stability of the motor during operation.

[0037] In this embodiment, the combination of boss 303 and annular body 302 forms a structure with layers and functional divisions for vibration damper 3. Boss 303 can closely mate with connecting ring groove 101 on the end face of motor body 1, providing a stable support point for motor body 1. Annular body 302 extends outward for connection to bracket 2. This structural arrangement makes the connection between motor body 1 and bracket 2 more reasonable and effective, improving the structural stability and compactness of the entire motor assembly. Boss 303 is embedded in connecting ring groove 101 of motor body 1, increasing the contact area and connection strength between vibration damper 3 and motor body 1. After annular body 302 is snapped into mounting hole 201 of bracket 2, it further evenly transfers the load of motor body 1 to bracket 2. The two work together to make the connection between motor body 1 and bracket 2 more secure, capable of withstanding greater radial and axial forces, and reducing vibration and displacement of the motor during operation. Boss 303 and ring body 302 together form a complete vibration damping system. During motor operation, boss 303 reduces vibration transmission between motor body 1 and vibration damper 3, while ring body 302 acts as a buffer and isolation between motor body 1 and bracket 2, effectively absorbing and dissipating vibration energy, reducing the motor's vibration amplitude and noise level, and improving the smoothness and comfort of motor operation. Furthermore, the structure and installation method of this vibration damper 3 are versatile and adaptable, suitable for motor bodies 1 and brackets 2 of different specifications and models. The size and shape of boss 303 and ring body 302 can be adjusted according to actual needs.

[0038] As a specific embodiment, the ring body 302 is usually made of a material with a certain elasticity. During the operation of the motor, it can effectively absorb and buffer the vibration energy generated by the motor, reduce the transmission of vibration to the bracket 2 and surrounding structures, thereby reducing the noise during the operation of the motor and improving the comfort of the use environment. At the same time, it also protects the bracket 2 and other related components from damage caused by vibration, thereby improving the reliability and durability of the entire system.

[0039] See also Figures 1 to 8 As shown, the outer peripheral wall of the vibration damper 3 is provided with an outer edge ring groove 301, that is, the outer peripheral wall of the circular ring body 302 is provided with an outer edge ring groove 301, and the outer edge ring groove 301 is clamped in the mounting hole 201. The outer edge ring groove 301 has a certain depth and width and can be firmly clamped in the mounting hole 201.

[0040] In this embodiment, the cooperation of the outer ring groove 301 and the mounting hole 201 increases the contact area between the vibration damper 3 and the bracket 2. This helps to more evenly distribute the weight of the motor body 1 and the load generated during operation, reduces local stress concentration, and thus enhances the stability of the connection between the vibration damper 3 and the bracket 2. The provision of the outer ring groove 301 increases the friction and mechanical locking effect between the vibration damper 3 and the mounting hole 201. During motor operation, even when subjected to vibration and impact, the vibration damper 3 is unlikely to loosen or be pulled out of the mounting hole 201, thus ensuring the reliability of the connection between the motor and the bracket 2. The shape and structure of the outer ring groove 301 provide additional elastic deformation space for the vibration damper 3. When the motor vibrates, the outer ring groove 301 can better adapt to and buffer these vibrations, allowing the vibration damper 3 to more effectively absorb and dissipate vibration energy, thereby improving the vibration damping effect. Through the cooperation of the outer ring groove 301 and the mounting hole 201, the stress of the vibration damper 3 is more evenly distributed between the vibration damper 3 and the bracket 2 when subjected to vibration loads. This helps reduce the risk of fatigue damage to the vibration damper 3 and bracket 2, extending their service life. The outer ring groove 301 matches the shape of the mounting hole 201, allowing for quick alignment and snapping into place during installation, ensuring that the vibration damper 3 is correctly installed in the designated location and improving installation accuracy and efficiency. The provision of the outer ring groove 301 allows the vibration damper 3 to be tightly embedded in the mounting hole 201, reducing the need for additional fixing components (such as screws and nuts), thereby optimizing the structural layout of the motor assembly and making the entire system more compact. This arrangement integrates the fixing function of the vibration damper 3 into its own structure, eliminating the need for additional connectors, reducing the number and complexity of components, improving production efficiency, and reducing potential points of failure.

[0041] See also Figures 1 to 8 As shown, with the longitudinal section of the vibration damper 3 as the projection surface, the diameter of the annular body 302 is larger than the diameter of the boss 303 , and a step surface is formed at the connection between the annular body 302 and the boss 303 , which abuts against the end face of the motor body 1 .

[0042] In this embodiment, the stepped surface abuts the end face of the motor body 1, preventing excessive axial movement of the motor body 1, ensuring the stable position of the motor body 1 on the bracket 2 and avoiding increased vibration or loosening of the assembly due to axial displacement. The larger diameter of the annular main body 302 cooperates with the mounting hole 201 of the bracket 2 to limit radial sway of the motor body 1, ensuring that the central axis of the motor body 1 is aligned with the central axis of the bracket 2, and reducing radial vibration and oscillation. The stepped surface has a large contact area with the end face of the motor body 1, which can more evenly distribute the weight of the motor body 1 and the load generated during operation, thereby improving the stability of the connection. The close contact between the stepped surface and the end face of the motor body 1 increases friction, preventing the vibration damper 3 from loosening due to vibration during motor operation, and ensuring the reliability of the connection. In addition, the stepped surface plays a guiding and positioning role during the installation process, ensuring that the vibration damper 3 is accurately installed and improved installation efficiency. The close contact between the stepped surface and the end face of the motor body 1 reduces the gap between them, preventing external impurities such as dust and moisture from entering the interior of the motor, and improving the protective performance of the motor.

[0043] See also Figures 1 to 8 As shown, the end face of the boss 303 facing the connecting ring groove 101 is provided with a plurality of protrusions 304, and the plurality of protrusions 304 form a T-shaped protrusion 304. The plurality of protrusions 304 are arranged at intervals in the circumferential direction of the end face of the boss 303. The connecting ring groove 101 is provided with a plurality of positioning holes 111 at intervals, and the protrusions 304 are clamped in the positioning holes 111.

[0044] Specifically, ensure that the boss 303 matches the shape and size of the connecting ring groove 101, align the T-shaped protrusion 304 on the boss 303 with the positioning hole 111 in the connecting ring groove 101, and completely insert the boss 303 of the vibration damper 3 into the connecting ring groove 101, ensuring that the T-shaped protrusion 304 is snapped into the positioning hole 111. Align the front cover 4 and rear cover 5 of the motor body 1 with the two side walls of the bracket 2 respectively. At the same time, ensure that the annular body 302 of the vibration damper 3 is aligned with the mounting hole 201 on the side wall of the bracket 2, and snap it into the mounting hole 201 completely to ensure that the vibration damper 3 is firmly installed and not loose.

[0045] In this embodiment, multiple protrusions 304 are spaced apart in the circumferential direction of the end surface of the boss 303, corresponding one-to-one with and engaging the multiple positioning holes 111 in the connecting ring groove 101. This allows the vibration damper 3 to be quickly and accurately positioned during installation, ensuring its precise connection position with the motor body 1. After the protrusions 304 are engaged with 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 the two tighter and more secure. This helps to improve the vibration damper 3's ability to resist axial and radial forces, reduces the risk of loosening caused by vibration during operation of the motor, and enhances the overall reliability of the motor assembly. The multiple 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 the load being concentrated at a few points. This helps to reduce local stress concentration, increase the service life of the vibration damper 3 and the motor body 1, and reduce the risk of component damage due to excessive stress. The combination of T-shaped protrusions 304 and positioning holes 111 forms a multi-point support structure, optimizing the path of vibration transmission from motor body 1 to vibration damper 3. This structure more effectively absorbs and cushions vibration generated by the motor, reducing the transmission of vibration to bracket 2 and surrounding structures, thereby enhancing the vibration damping effect of the entire motor assembly and reducing noise and vibration levels. The provision of multiple protrusions 304 further stabilizes the installation of vibration damper 3 on the end face of motor body 1, reducing vibration and sway of vibration damper 3 itself. This allows vibration damper 3 to better perform its vibration damping function, improve the smoothness of motor operation, and reduce secondary vibration problems caused by the instability of vibration damper 3. Arranging multiple protrusions 304 on the limited end face of the boss 303 can improve the connection strength and stability between the vibration damper 3 and the motor body 1 without increasing additional space. This arrangement fully utilizes the space of the connecting ring groove 101 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 integrated setting of the equipment. By arranging multiple protrusions 304 on the end face of the boss 303 and cooperating with the positioning hole 111, the use of other auxiliary fixing components (such as screws, retaining rings, 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 and improving product reliability and maintainability.

[0046] See also Figures 1 to 8 As shown, a snap ring groove 305 is provided at the connection between the protrusion 304 and the boss 303 . The protrusion 304 extends into the motor body 1 through the positioning hole 111 , and the snap ring groove 305 is snapped into the positioning hole 111 .

[0047] Specifically, align the boss 303 of the vibration damper 3 with the connecting ring groove 101 on the end face of the end cap, ensuring 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 the vibration damper 3 until the boss 303 is 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 cap. Continue to press the vibration damper 3 until the protrusion 304 fully mates with the positioning hole 111 and the snap ring groove 305 snaps into the positioning hole 111, ensuring that the vibration damper 3 is firmly installed and not loose.

[0048] In this embodiment, after protrusion 304 passes through positioning hole 111 and extends into motor body 1, it forms a tighter fit with the internal structure of motor body 1, effectively preventing vibration damper 3 from rotating within connecting ring groove 101 on the end face of motor body 1, ensuring relative stillness between vibration damper 3 and motor body 1, and improving the stability of the motor during operation. After protrusion 304 extends into motor body 1, it increases the connection strength between vibration damper 3 and motor body 1, making it more difficult to pull vibration damper 3 out of connecting ring groove 101, enhancing the firmness and reliability of the connection, and reducing the risk of loosening due to vibration. Protrusion 304 extends into the interior of motor body 1, forming a deeper connection structure, further optimizing the path of vibration transmission from motor body 1 to vibration damper 3. This enables vibration damper 3 to more effectively absorb and buffer vibrations generated by the motor, reducing the transmission of vibrations to bracket 2 and surrounding structures, thereby improving the vibration damping effect of the entire motor assembly. After protrusion 304 extends into motor body 1, it provides more space for elastic deformation for vibration damper 3, enabling it to better adapt to and buffer vibrations generated during motor operation, further improving the vibration damping effect. Protrusion 304 extends into the interior of motor body 1, fully utilizing the space within motor body 1 and making the entire motor assembly more compact, which is conducive to the miniaturization and integration of the equipment. This arrangement can reduce or avoid the use of other auxiliary fixing components (such as screws, retaining rings, etc.), simplifying the structure of the motor assembly, reducing production costs and assembly complexity, while also reducing potential failure points and improving product reliability and maintainability.

[0049] In this embodiment, the snap ring groove 305 is snapped into the positioning hole 111. By increasing friction and providing a mechanical locking effect, it prevents the vibration damper 3 from loosening or falling off due to vibration during motor operation, thereby ensuring the reliable connection between the vibration damper 3 and the motor body 1. The provision of the snap ring groove 305 makes it more difficult to remove the vibration damper 3 in the axial direction, enhancing the firmness of the connection and ensuring the stability of the vibration damper 3 during long-term operation. The combination of the snap ring groove 305 and the positioning hole 111 provides a clear installation position for the vibration damper 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.

[0050] See also Figures 1 to 8 As shown, a cross-shaped groove 306 is formed on the end surface of the protrusion 304 facing away from the boss 303 , and the cross-shaped groove 306 passes through the end surface of the protrusion 304 .

[0051] In this embodiment, the cross-shaped groove 306 weakens the rigidity of the protrusion 304, making it more susceptible to elastic deformation when subjected to vibration, thereby better absorbing and buffering vibration energy and enhancing the vibration reduction effect. The provision of the cross-shaped groove 306 gives the protrusion 304 good elastic deformation ability in multiple directions, effectively responding to vibration from different directions and improving the vibration reduction performance of the vibration damping member 3. During installation, the cross-shaped groove 306 imparts a certain degree of elasticity to the protrusion 304, making it easier to pass through the positioning hole 111 and extend into the motor body 1, reducing installation difficulty and improving installation efficiency. Similarly, during disassembly, the elastic provision of the cross-shaped groove 306 makes it easier to pull the protrusion 304 out of the positioning hole 111, simplifying the disassembly process and facilitating maintenance and replacement.

[0052] As a specific implementation, the annular body 302 and the boss 303 are both made of silicone material, and a through hole is coaxially opened in the middle of the annular body 302 and the boss 303. The size of the through hole is consistent with the outer diameter of the end cover bearing chamber, ensuring the accuracy of installation with the end cover.

[0053] See also Figures 1 to 12 As shown, the bracket 2 is die-casted by cold-rolled steel plate, and its upper part is a semicircular structure, that is, the mounting hole 201 is a semicircular structure, and the arc angle is hand-holding type. The bracket 2 includes a first arm 21 and a second arm 22 arranged opposite to each other, and the first arm 21 and the second arm 22 are respectively provided with a mounting hole 201, and the mounting hole 201 has a fracture, and the two ends of the fracture are respectively provided with a first hook 202 and a second hook 203, and part of the wall surface of the vibration damper 3 is installed in the mounting hole 201, and the first hook 202 and the second hook 203 are reversely facing the vibration damper 3, and the first hook 202 and the second hook 203 are clamped with the outer edge of the vibration damper 3.

[0054] Specifically, the front end cover 4 and the rear end cover 5 are connected to form the outer shell of the motor body 1, and then the bearings are installed in the bearing chambers of the front end cover 4 and the rear end cover 5 respectively. Finally, the rotating shaft 6 is inserted into the bearing, and the boss 303 of the vibration damper 3 is aligned with the connecting ring groove 101 on the end face of the motor body 1, and the protrusion 304 on the boss 303 is aligned with the positioning hole 111 in the connecting ring groove 101. Press the vibration damper 3 to allow the boss 303 to be completely embedded in the connecting ring groove 101. At the same time, the protrusion 304 passes through the positioning hole 111 and extends into the motor body 1. Let the front end cover 4 and the rear end cover 5 of the motor body 1 face the two side walls of the bracket 2 respectively, and at the same time let the circular ring body 302 of the vibration damper 3 face the mounting hole 201 on the side wall of the bracket 2. Facing the mounting hole 201, press the circular ring body 302 of the vibration damper 3 inward so that a part of the circular ring body 302 enters the mounting hole 201. The first hook 202 and the second hook 203 are engaged with the outer edge of the vibration damper 3 to form a tight connection, ensuring that the vibration damper 3 is firmly installed.

[0055] In this embodiment, the first hook 202 and the second hook 203 face opposite directions from the vibration damper 3 and engage with the outer edge of the vibration damper 3, forming a secure engagement structure. This prevents the vibration damper 3 from loosening from the mounting hole 201 during use, ensuring the stability of the connection between the vibration damper 3 and the bracket 2. Even in the vibration environment of motor operation, the vibration damper 3 can be kept fixed. The engagement of the hook with the outer edge of the vibration damper 3 increases the connection strength between the vibration damper 3 and the bracket 2, making the two more tightly connected, improving the overall rigidity of the motor assembly, helping to reduce the vibration amplitude of the motor during operation, reducing the risk of wear and fatigue damage to components caused by vibration, and extending the service life of the motor. The provision of the hook allows the vibration damper 3 to be quickly and accurately engaged in the mounting hole 201 without the need for complex tools and tedious operating steps, simplifying the assembly process, improving production efficiency, reducing labor costs, and facilitating subsequent disassembly and maintenance. If the vibration damper 3 needs to be disassembled, the hook structure also makes the connection between the vibration damper 3 and the bracket 2 relatively easy to disconnect, facilitating maintenance and replacement. The hook provides a clear installation position for the vibration damper 3, ensuring that its connection with the bracket 2 is precisely aligned, avoiding problems such as motor eccentricity due to installation deviation, improving assembly quality and efficiency, and ensuring the performance and reliability of the motor assembly. The hook is connected to the outer edge of the vibration damper 3, so that the weight and vibration load of the motor body 1 can be evenly transferred to the bracket 2, avoiding local stress concentration, reducing the risk of deformation or damage caused by uneven force on the bracket 2, enhancing the structural stability and load-bearing capacity of the entire motor assembly, and ensuring the stability of the motor during operation.

[0056] See also Figures 1 to 12As shown, the outer edge of the vibration damper 3 is circumferentially formed with a first self-locking groove 307 and a second self-locking groove 308. The outer ring of the vibration damper 3 is circumferentially covered with a reinforcement ring 309. The reinforcement ring 309 is a steel ring that matches the shape of the vibration damper 3 and covers the groove walls of the first and second self-locking grooves 307 and 308. In other words, the reinforcement ring 309 is a monolithic structure with a continuous transition even at the self-locking grooves. The first hook 202 engages the first self-locking groove 307, and the second hook 203 engages the second self-locking groove 308. The steel ring is galvanized and passivated to make it more durable and sturdy.

[0057] Specifically, align the annular body 302 of the vibration damper 3 with the mounting hole 201 on the side wall of the bracket 2. At the same time, ensure that the first self-locking groove 307 and the second self-locking groove 308 on the outer circumference of the vibration damper 3 are aligned with the first hook 202 and the second hook 203 in the mounting hole 201 of the bracket 2, respectively. Press the annular body 302 of the vibration damper 3 so that it partially enters the mounting hole 201. During the pressing process, the first hook 202 and the second hook 203 will respectively contact the first self-locking groove 307 and the second self-locking groove 308 covered by the reinforcement ring 309.

[0058] In this embodiment, the reinforcement ring 309 is a steel ring with high rigidity and strength. After being covered around the outer ring of the vibration damper 3, it can significantly improve the rigidity of the vibration damper 3 and prevent the vibration damper 3 from being deformed due to radial force or axial force during use, thereby ensuring the shape and dimensional stability of the vibration damper 3 and extending its service life. It covers the groove walls of the first self-locking groove 307 and the second self-locking groove 308, thereby enhancing the structural strength of the self-locking groove, making the connection between the hook and the self-locking groove more firm and reliable, preventing the hook from loosening due to deformation of the groove wall of the self-locking groove, and improving the overall stability and reliability of the motor assembly. The covering of the reinforcement ring 309 enables the outer edge of the vibration damper 3 to have appropriate elastic deformation ability when the hook is inserted into the self-locking groove, which not only ensures that the hook can be smoothly inserted into the self-locking groove, but also provides sufficient clamping force, so that the connection between the vibration damper 3 and the bracket 2 is tight and not easy to loosen. The shape of the reinforcement ring 309 matches the vibration damper 3, which can ensure the consistency of the circumferential size of the outer edge of the vibration damper 3, thereby improving the accuracy and consistency of the clamping, and avoiding the problem of loose or skew clamping due to the irregular shape of the vibration damper 3.

[0059] As a specific embodiment, a convex groove 310 is opened on the outer edge of the annular body 302. During the assembly process with the bracket 2, the convex groove 310 can be elastically deformed, and the first hook 202 and the second hook 203 of the bracket 2 can be more easily installed in the corresponding self-locking groove.

[0060] See also Figures 1 to 12As shown, with the cross section of the vibration damping member 3 as the projection surface, the first self-locking groove 307 and the second self-locking groove 308 are both trapezoidal, the first self-locking groove 307 has a first sharp angle, the angle of the first sharp angle is A, and the angle A satisfies: 65°≤A≤85°; the second self-locking groove 308 has a second sharp angle, the angle of the second sharp angle is 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°, and the hook tip angle of the second hook 203 is b, and the angle b satisfies: 30°≤b≤60°.

[0061] In this embodiment, the first tip 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°. There is an overlap in the angle ranges of the two, which can achieve precise matching, so that the hook and the self-locking groove are tightly engaged, ensuring that the vibration damper 3 will not loosen due to vibration and other reasons after installation, thereby improving the reliability of the connection. The first self-locking groove 307 and the second self-locking groove 308 are both trapezoidal. This trapezoidal structure makes it difficult for the vibration damper 3 to move axially and radially once the hook is engaged due to the lateral support of the trapezoid, thereby enhancing the stability of the engagement and preventing the vibration damper 3 from being displaced or rotated when the motor is running. The second sharp 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 hook to be smoothly guided into the self-locking groove during the assembly process, reducing the resistance and difficulty during assembly and improving the assembly efficiency. The reasonable angle setting enables the hook to produce appropriate elastic deformation during the clamping process, which can not only ensure the tightness of the clamping, but also prevent the hook or self-locking groove from being damaged due to excessive deformation, making the assembly process smoother, reducing the assembly difficulty and the requirements for assembly tools. The reasonable angle setting enables the hook and the self-locking groove to evenly distribute the stress along the angular direction when subjected to force, avoiding local stress concentration, improving the fatigue life of the clamping part, and extending the service life of the vibration damper 3 and the bracket 2. The precise angle matching makes the connection between the vibration damper 3 and the bracket 2 tighter and more stable, and can more effectively absorb and dissipate the vibration energy generated by the motor during operation, reducing the vibration amplitude and noise level of the motor, and improving the vibration reduction effect of the entire motor assembly.

[0062] See also Figures 1 to 12 As shown, the first arm 21 and the second arm 22 both include a first cantilever 241 and a second cantilever 242, the first cantilever 241 is provided with a first hook 202, the second cantilever 242 is provided with a second hook 203, and a mounting hole 201 is formed between the first cantilever 241 and the second cantilever 242. In the horizontal direction, the first cantilever 241 and the second cantilever 242 are inclined to the same side so that an upward converging anti-slip structure is formed between the first cantilever 241 and the second cantilever 242.

[0063] In this embodiment, the upward-converging anti-slip structure makes it difficult for the vibration damper 3 to slip out of the mounting hole 201 in the vertical direction once it is installed. During the operation of the motor, even if it is subjected to vibration and impact, the vibration damper 3 can remain stable, ensuring the reliability of the connection between the motor and the bracket 2. This structure limits the displacement of the vibration damper 3 in all directions, especially preventing it from slipping out upward in the vertical direction, thereby enhancing the stability of the overall structure. The setting of the anti-slip structure enables the stress to be evenly distributed along the inclined cantilever when subjected to load, avoiding stress concentration, enhancing the structural strength of the bracket 2, and extending its service life. The inclined cantilever setting makes the entire bracket 2 structure more compact, optimizes space utilization, and improves the overall strength of the structure.

[0064] As a specific embodiment, with the side of the bracket 2 as the projection surface, the bracket is die-cast using cold-rolled steel plate. The left side of the bracket 2 extends to the first arm 21 using a hypotenuse. In the vertical direction, the angle between the hypotenuse and the bottom of the bracket 2 is e, and the angle e satisfies: 90°≤d≤180°. The angle between the hypotenuse and the outer side of the first arm 21 is c, and the angle c satisfies: 90°≤c≤180°. The angle between the outer side of the second arm 22 and the bracket 2 in the vertical direction is d, and the angle d satisfies: 90°≤d≤180°. The setting of angles e, c, and d makes the first arm 21 and the second arm 22 form a "hand-holding" type, ensuring that the motor body 1 can stably bear the weight of the motor and will not fall off when it is horizontally installed in the load and operates. The width of the bracket 2 is consistent with the width of the end cover after the vibration damper 3 is installed, ensuring the accuracy of installation.

[0065] See also Figures 1 to 13 As shown, the motor further includes a capacitor box 7, which is mounted on the bottom of the bracket 2. A buckle 8 is provided at the bottom of the bracket 2. A slot 701 is provided on the side wall of the capacitor box 7 facing the buckle 8, and the buckle 8 snaps into the slot 701. A limit slot is also provided at the bottom of the bracket 2 to limit the position of the capacitor box 7. The sides and bottom of the bracket 2 are reinforced with ribs, one of which is longer and is ≤10mm from the curved edge of the upper mounting hole 201. This further ensures the strength of the bracket 2 and the reliability of the motor during operation.

[0066] In this embodiment, the arrangement of the buckle 8 and the slot 701 enables the capacitor box 7 to be quickly installed on the bracket 2 without the use of fasteners such as screws, thereby simplifying the installation steps and improving installation efficiency. Similarly, this structure also facilitates the disassembly of the capacitor box 7, making it easy to maintain, replace or upgrade the capacitor box 7. After the buckle 8 is inserted into the slot 701, it can tightly fix the capacitor box 7, preventing it from loosening or falling off due to vibration or other reasons during the operation of the motor, thereby ensuring the reliability of the connection between the capacitor box 7 and the bracket 2. The limit groove limits the capacitor box 7, restricting the displacement of the capacitor box 7 in all directions, further enhancing the stability of the capacitor box 7 installation, and ensuring its reliability in long-term use. Installing the capacitor box 7 at the bottom of the bracket 2 fully utilizes the vertical space of the motor assembly, making the layout of the entire motor assembly more compact, and is conducive to the miniaturization and integrated setting of the device. This arrangement avoids setting a separate installation position for the capacitor box 7, reducing the demand for additional space for the capacitor box 7, and improving the space utilization rate of the device.
