Description

Technical Field

[0001] This utility model relates to the technical field of motor vibration damping structures, and in particular to a motor mounting structure. Background Technology

[0002] In modern industrial production and daily life, various types of rotary motion actuators—i.e., motors—are widely used in mechatronic equipment. As people's demands for product quality continue to increase, while pursuing high performance, they also place greater emphasis on low-noise operation and long lifespan. To effectively reduce the vibration generated by motor operation, the industry currently employs two main methods: The first is to use spring sheets or rubber pads as buffer elements placed between the stator assembly and the housing to form a flexible support system. The advantage is low cost and ease of processing, but the disadvantages are also very obvious, such as poor durability, easy aging and failure, resulting in loss of original vibration isolation performance and poor reliability, and low absorption efficiency for high-frequency, short-waveform disturbances. The second method introduces the concept of magnetic levitation, allowing the rotating shaft to be decoupled from physical contact and relying on electromagnetic force to achieve a non-physical connection, thereby avoiding frictional losses and effectively blocking the transmission path. However, this method is complex in construction and difficult to maintain. More importantly, it requires additional power supply support, making it unsuitable for the application environments of some portable equipment, limiting its applicability. Therefore, it is necessary to design a motor mounting structure that is simple in structure, easy to maintain, and not prone to aging and failure. Utility Model Content

[0028] Please refer to Figures 1-6This utility model provides a motor mounting structure 100, which includes a mounting housing 110 and a shock-absorbing mounting component 120. The shock-absorbing mounting component 120 includes a mounting body 121 and an extension arm 122. The mounting body 121 is connected to the extension arm 122, and the shock-absorbing mounting component 120 is mounted on the mounting housing 110 via the extension arm 122, such that the mounting body 121 and the mounting housing 110 are spaced apart. The extension arm 122 is made of an elastic material, and the mounting body 121 has a mounting groove 1211 for mounting the motor. Exemplarily, the shock-absorbing mounting component 120 mainly includes, but is not limited to, an integrally wrapped shock-absorbing collar made of silicone material, which is tightly fitted to the outside of the motor windings and fixed to the end cap. Furthermore, the shock-absorbing mounting component 120 is secured with screws to ensure a good overall seal and prevent loosening. In actual assembly, a suitable thickness specification can be selected according to the specific model to ensure that heat dissipation is not affected while achieving optimal sound insulation and noise reduction effects. To achieve ideal mechanical properties and durability, in this embodiment, a special medical-grade liquid injection molding (LSR) silicone with high tear strength, excellent resilience, and resistance to compressive deformation is selected to fabricate the aforementioned shock-absorbing mounting component 120. This material not only meets food hygiene standards and is safe and reliable, but also has a fast production cycle and is easy to mass-produce in customized quantities to suit the small household appliances or other consumer goods markets with different sizes and shapes. The working process and principle of the shock-absorbing mounting component 120: When the motor starts, the centrifugal force causes the rotating parts to produce a slight radial oscillation tendency. At this time, the soft elastic layer, which is completely covered, will undergo slight expansion and contraction changes in a timely manner, playing an automatic adjustment function similar to a sponge to prevent excessive wear and damage to core components, thus avoiding unnecessary economic losses.

[0029] Vibration damping mount 120 is an innovative noise suppression technology and process applied to various mechanical equipment. Based on current mainstream vibration isolation concepts, it offers a novel solution designed to better protect sensitive electronic components from damage while also providing a superior tactile experience. Its unique feature lies in the ingenious use of soft yet resilient silicone as an intermediary barrier, effectively separating internal and external spaces and significantly enhancing resistance to accidental impacts.

[0030] In this embodiment, the motor mounting structure 100 has an extension arm 122 on the mounting body 121. The extension arm 122 is made of elastic material, so that the vibration generated by the motor when it is working is canceled by the deformation of the extension arm 122. At the same time, since the mounting body 121 and the mounting housing 110 are spaced apart, the vibration generated by the motor and the mounting body 121 is suspended, which greatly reduces the noise generated by the motor vibration and helps to further avoid noise generated by collisions between the motor, the mounting body 121 and other components.

[0031] In one possible implementation, the mounting body 121 is made of an elastic material. Exemplarily, the material of the mounting body 121 is the same as that of the extension arm 122. The mounting body 121, made of an elastic material, is capable of absorbing and cushioning vibrations generated by the motor during operation. When the motor operates, its mechanical vibrations are transmitted to the mounting body 121, and the elastic material can counteract these vibrations through its own deformation, thereby reducing the impact of vibrations on the motor and surrounding structures. Because the elastic material effectively absorbs vibrations, the noise generated during motor operation can be significantly reduced. This damping effect not only improves the smoothness of equipment operation but also provides a quieter working environment for the user. The cushioning effect of the elastic material reduces hard contact between the motor and the mounting housing 110, avoiding mechanical wear caused by vibration. This wear reduction effect helps extend the service life of the motor and mounting structure, reducing equipment maintenance costs. The mounting body 121, made of an elastic material, can adapt to different working environments and conditions, maintaining good damping performance even under high-frequency vibration or long-term operation, thereby improving the overall reliability of the equipment. The use of an elastic material mounting body 121 simplifies the design of the motor mounting structure 100. Compared to traditional damping elements such as spring sheets or rubber pads, the mounting body 121 made of elastic material can be directly integrated into the mounting structure without the need for additional damping elements, thus simplifying structural design and reducing manufacturing costs. The use of elastic material provides greater design flexibility. The shape, size, and material properties of the mounting body 121 can be adjusted according to different motor models and application scenarios to achieve optimal vibration damping performance.

[0032] Please refer to Figure 5 In one possible implementation, the width of the mounting body 121 is denoted as H, and the length of the extension arm 122 is denoted as D, wherein the ratio between the length D of the extension arm 122 and the width H of the mounting body 121 is not less than 0.5. Exemplarily, the ratio D / H can be 0.5, 0.6, 0.7, or 0.8. The length D of the extension arm 122 determines the range of elastic deformation it can provide. When the ratio of D to the width H of the mounting body 121 is not less than 0.5, the extension arm 122 has sufficient length to absorb and buffer vibrations generated by the motor. A longer extension arm 122 can provide a larger elastic deformation space during motor operation, thereby more effectively counteracting vibrations.

[0033] Please refer to Figure 6In one possible implementation, the thickness of the mounting body 121 is denoted as X, and the thickness of the extension arm 122 is denoted as Y, wherein the ratio between the thickness X of the extension arm 122 and the thickness Y of the mounting body 121 is in the range of [0.05, 0.2]. For example, the X / Y ratio can be 0.05, 0.1, 0.15, or 0.2. The thickness X of the extension arm 122 determines its elastic deformation capability, while the thickness Y of the mounting body 121 affects its overall rigidity. When the X / Y ratio is in the range of [0.05, 0.2], the extension arm 122 can provide sufficient elastic deformation to absorb the vibration generated by the motor, while the thickness Y of the mounting body 121 ensures that it maintains sufficient strength and stability during vibration. This design can effectively reduce the amplitude of motor vibration transmitted to the mounting housing 110, thereby reducing noise and vibration during equipment operation and improving the smoothness and comfort of equipment operation. With an X / Y ratio within the range of [0.05, 0.2], the extension arm 122 ensures sufficient elastic deformation capacity to absorb vibration while avoiding insufficient structural rigidity due to excessive thickness. The thickness Y of the mounting body 121 provides sufficient support, ensuring that the entire structure does not deform excessively or loosen during vibration. This design significantly improves the stability of the motor mounting structure 100, ensuring that the motor maintains a stable position and posture even under high vibration or high load conditions during operation, preventing structural loosening or damage caused by vibration.

[0034] Please refer to Figure 3In one possible implementation, the distance between the mounting body 121 and the bottom surface of the mounting housing 110 is denoted as L, where the ratio of L / Y is in the range of [0.3, 0.5]. For example, the ratio of L / Y can be 0.3, 0.35, 0.4, 0.45, or 0.5. The distance L between the mounting body 121 and the bottom surface of the mounting housing 110 determines the movement space of the motor and its mounting body 121 during vibration. When the ratio of L to the thickness Y of the extension arm 122 is in the range of [0.3, 0.5], it means that the vibration generated by the motor during operation can be effectively buffered and isolated by the elastic deformation of the extension arm 122. The thickness Y of the extension arm 122 determines its elastic deformation capability, while the size of L provides sufficient space for this deformation. This design ensures that the motor does not directly contact the bottom surface of the mounting housing 110 during vibration, thereby avoiding noise and mechanical damage caused by hard impacts, while also better isolating vibration and reducing the possibility of vibration being transmitted to other components. The L / Y ratio, within the range of [0.3, 0.5], ensures sufficient movement space while preventing excessive distance between the mounting body 121 and the mounting housing 110. If the L / Y ratio is too small, the motor may collide with the bottom surface of the mounting housing 110 during vibration; conversely, if the ratio is too large, the stability of the mounting body 121 during vibration may decrease, or even cause wobbling. By properly controlling the L / Y ratio, the stability of the motor during operation can be ensured, while also guaranteeing the reliability of the entire mounting structure and preventing structural loosening or damage due to vibration.

[0035] Please refer to Figure 5In one possible implementation, multiple extension arms 122 are provided, symmetrically distributed along the central axis K of the mounting body 121. Exemplarily, four extension arms 122 are provided, with two on each side of the central axis K of the mounting body 121. During operation, the motor generates vibrations, which are transmitted to the extension arms 122 via the mounting body 121. Since the extension arms 122 are made of elastic material, their deformation can absorb and cancel vibration energy. When multiple extension arms 122 are symmetrically distributed along the central axis K, they can absorb vibrations uniformly from multiple directions, making the mutual cancellation of vibrations in each direction more significant. This symmetrically distributed distribution of extension arms 122 can more effectively reduce the transmission of motor vibrations, thereby reducing the overall vibration amplitude of the equipment and improving the smoothness of equipment operation. The symmetrically distributed extension arms 122 can ensure the consistency of the damping effect in all directions. Since the elastic material of the extension arms 122 has similar deformation capabilities in all directions, the symmetrical distribution ensures that vibrations are effectively absorbed and buffered in all directions. This design can significantly improve vibration damping performance, reduce noise and mechanical wear caused by vibration, and improve the operating efficiency and reliability of the equipment.

[0036] Please refer to Figure 4 , Figure 5 and Figure 6 In one possible implementation, the extension arm 122 includes an extension section 1221 and a mounting part 1222. The mounting body 121 and the mounting part 1222 are connected by the extension section 1221. The mounting part 1222 is provided with a mounting hole 1223. The mounting housing 110 includes a fixing post 111. The mounting hole 1223 and the fixing post 111 are connected by bolts.

[0037] In one possible implementation, the mounting housing 110 includes a support portion 112, with an extension arm 122 located directly below the support portion 112 and spaced apart from it. Exemplarily, the support portion 112 is a rectangular plate, and the width of the rectangular plate is greater than the width of the extension arm 122. This allows the support portion 112 to provide support when the extension arm 122 deforms, preventing excessive deformation and breakage, thus improving the service life of the vibration-damping mounting component 120. The support portion 112 is part of the mounting housing 110, located directly above the extension arm 122, and spaced apart from it. This design allows the entire mounting structure to provide additional support through the support portion 112 when subjected to motor vibration, preventing the mounting body 121 and the extension arm 122 from shifting position or deforming due to excessive vibration. The presence of the support portion 112 significantly enhances the stability of the entire motor mounting structure 100, ensuring that the motor maintains a stable position and posture even under high vibration or high load conditions during operation, preventing structural loosening or damage caused by vibration. The spacing design between the support portion 112 and the extension arm 122 allows the extension arm 122 to deform freely during vibration, while the support portion 112 limits excessive deformation of the extension arm 122. This design is similar to an "elastic buffer," allowing the extension arm 122 to exert its elastic damping function while preventing it from losing its damping capacity due to excessive deformation. The support portion 112 effectively improves vibration damping performance, reduces the amplitude of motor vibration transmitted to the mounting housing 110, thereby reducing noise and vibration during equipment operation and improving the smoothness and comfort of equipment operation.

[0038] Please refer to Figure 3 In one possible implementation, the mounting housing 110 includes a clearance groove 113 for clearing the output shaft of the motor.
