Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.

When the motor 30 works, the rotating shaft rotates and outputs torque, and the rotating shaft applies high-frequency acting force to the motor 30, so that the motor 30 generates high-frequency axial or radial reciprocating displacement, namely high-frequency vibration. Especially, in the motor 30 for generating the airflow, when the rotating shaft drives the blades to rotate, the airflow disturbance on the blades can be transmitted to the motor 30 itself, which aggravates the vibration of the motor 30. In addition, the motor 30 generates a certain noise due to friction of the related structure during operation. The mounting member 100 provided in one embodiment of the present application is intended to buffer the motor 30, absorb and isolate high-frequency vibration and noise of the motor, and prevent the transmission to an external structure.

As shown in fig. 1 to 6, the mounting member 100 includes a buffer structure 10 for wrapping the motor 30, the buffer structure 10 includes a plurality of buffer portions 15 and at least one hollow portion 14, and the buffer portions 15 include a protrusion structure 151 formed of a flexible material.

The hollow portion 14 is equivalent to removing a part of material at some positions of the buffer structure 10 to form a hollow shape, so that the buffer structure 10 has structures such as a through hole, a through cavity, a notch, and the like. The buffer structure 10 is easy to deform at the edge of the hollow-out portion 14, so that the buffer structure 10 provided with one or more hollow-out portions 14 has a larger deformation space, which is equivalent to reducing the overall structural strength of the buffer structure 10, so that the buffer structure is easy to be stretched and compressed to deform, thereby being beneficial to absorbing fine and high-frequency vibration. In addition, after the hollow-out portion 14 is formed in the buffering structure 10 in the embodiment, the material of the hollow-out portion 14 is also saved, so that the consumed material cost is lower, and on the premise of providing the same or better buffering vibration isolation capability, the volume occupied by the buffering structure 10 in the embodiment is smaller, which is more favorable for space arrangement.

The cushioning structure 10 itself provided with the hollowed-out portion 14 is easily deformed by tension and compression. When the buffer structure 10 is mounted to the motor 30, compared with a structure without hollowing out, the buffer structure 10 is more easily stretched to be enlarged and sleeved outside the motor 30, so that the assembly between the buffer structure 10 and the motor 30 is easier.

It is easy to understand that, the greater the number and/or the greater the area of the hollowed-out portions 14 provided on the buffer structure 10, the lower the strength of the whole buffer structure 10, and the more suitable for the small high-speed motor with large vibration frequency and small vibration amplitude; conversely, the greater the strength of the entire buffer structure 10, the more suitable it is for a medium-and large-sized motor having a small vibration frequency and a large vibration amplitude.

The cushion structure 10 further includes a plurality of cushion portions 15, the cushion portions 15 include a projection structure 151, and the plurality of cushion portions 15 are distributed at a plurality of positions of the cushion structure 10 to form a plurality of positions capable of abutting against and cushioning the relevant structure. The protruding structure 151 is formed of a flexible material, i.e., a non-rigid material, such as rubber, silica gel, plastic, and asphalt, so that the protruding structure 151 can be compressed and deformed to a certain extent after being stressed, thereby absorbing vibration and isolating impact. In an embodiment, the entire buffer part 15 may be integrally formed by a flexible material (e.g., soft rubber), that is, the entire buffer part is made of the flexible material, which has a low production cost, and has low overall hardness and is easy to deform, and is suitable for the motor 30 with a small amplitude. In another specific embodiment, the buffer portion 15 may be a hard structure, and the protrusion 151 formed by a flexible material is extended from the hard structure, so that the overall rigidity is high and the motor 30 with a large amplitude is suitable.

In a specific embodiment, the motor 30 is indirectly fixed to an external rigid mounting structure (e.g., a mounting seat, a sleeve 20, etc.) through the mounting member 100, and the protruding structure 151 provided on the buffer structure 10 faces the outside of the motor 30, i.e., the protruding structure 151 abuts against the rigid mounting structure. When the motor 30 vibrates and generates operating noise, the protrusion 151 is pressed by the motor 30 and the rigid mounting structure to be compressed and deformed, thereby absorbing the vibration and noise of the motor 30 and preventing the vibration or noise from being transmitted to the rigid mounting structure. The convex structure 151 has a smaller contact area as a portion actually contacting the rigid mounting structure, and reduces noise and a propagation cross-sectional size of vibration compared to the case where the entire motor 30 contacts the rigid mounting structure, thereby absorbing and reducing vibration. In another embodiment, the motor 30 is indirectly fixed to an external rigid mounting structure (e.g., a mounting seat, a sleeve 20, etc.) through the buffer structure 10, and the protruding structure 151 disposed on the buffer structure 10 faces the motor 30, that is, the protruding structure 151 abuts against the motor 30, and the action principle and the technical effect are similar and will not be described again.

As can be seen from the above, the mounting device 100 of the present embodiment has the buffer structure 10 wrapped outside the motor 30, the hollow portion 14 of the buffer structure 10 can make the buffer structure 10 easily stretch or compress to generate elastic deformation when the motor 30 vibrates, so as to absorb and buffer vibration and noise, the flexible protrusion structure 151 of the buffer portion 15 can be elastically compressed and deformed in axial direction when an impact is applied, so as to absorb and buffer vibration and noise, the hollow portion 14 and the buffer portion 15 together achieve buffering and noise reduction of the motor 30, and the mounting device is particularly suitable for a small-sized super-speed motor with high-frequency vibration. In addition, due to the existence of the hollow part 14 and the protruding structure 151, the cross-sectional area of the transmission path of the running noise of the motor 30 itself is reduced, and the function of reducing the transmission of the noise can also be achieved, so that the noise reduction function is further achieved. The shock absorbing structure 10 can also absorb and absorb shock transmitted from the outside to the motor 30, thereby protecting the motor 30.

In addition, after the motor 30 is installed on the installation part 100, the hollow-out portion 14 formed in the buffer structure 10 can expose a local corresponding position of the motor 30, and therefore when a ground wire needs to be designed, the ground wire can be directly connected to the portion, exposed in the hollow-out portion 14, of the motor 30 by directly penetrating through any hollow-out portion 14, so that the ground wire can be directly connected to the motor 30 in the radial direction, the arrangement and design limitations of the related electrical structures 31 are small, and the optimization of the space setting of the motor 30 and the related structures nearby is facilitated. Similarly, for the control circuit, the conducting wire and other structures of the motor 30, the structure can also directly extend through the hollow part 14 in the radial direction to be connected with the motor 30, and the effects of small design limitation and favorable optimization of space setting are also achieved.

In some embodiments, as shown in fig. 2 and 3, cushioning portion 15 includes a base portion 152, and raised structures 151 are disposed on base portion 152. In any cushioning portion 15, the following relationship exists between the projection structure 151 and the base 152: the cross-sectional area of the raised structures 151 is less than or equal to 1/4 of the cross-sectional area of the base 152. The base 152 is used for absorbing and dispersing the force applied to the protruding structure 151, and the base 152 may be a rigid structure or a flexible structure, for example, a flexible material is used to integrally form the base 152 and the protruding structure 151.

During cushioning, the protrusion 151 is directly deformed by compression, and receives the related force, and the force applied to the protrusion 151 is transmitted to the base 152. According to the related pressure formula, the larger the area of the base portion 152, the more the force transmitted by the protrusion structure 151 to the buffer structure 10 is dispersed, so it can be understood that, under the premise that the surface area of the buffer structure 10 is not changed, the larger the number and/or the larger the area of the hollow portions 14, the smaller the available area of the buffer portion 15 is caused, and the smaller the area of the buffer portion 15, the larger the pressure applied to the motor 30 by the protrusion structure 151 after being stressed is caused. In order to allow the force transmitted by the raised structure 151 to be shared to reduce the relative pressure, it is necessary to ensure that the cross-sectional area of the base portion 152 in each cushioning portion 15 is at least four times the cross-sectional area of the raised structure 151, which is understood to mean a radial cross-section of the raised structure 151. It is also understood that, for the cushioning structure 10, the size of the cushioning portion 15 has a predetermined requirement, and it is required to reasonably disperse the force applied to the protrusion structures 151, so that it is required to ensure that each protrusion structure 151 is disposed on the base portion 152 having at least four times of the cross-sectional area thereof, and on the premise of satisfying the requirement, the hollow portions 14 may be disposed on the rest portions of the cushioning structure 10, and of course, the hollow portions 14 may not be disposed on these portions. On the premise that the area limitation is satisfied, the base 152 does not need a clear boundary and can play a role of distributing the force of the convex structure 151, for example, the base 152 may be a part of the edge of the hollow portion 14, or a plurality of bases 152 surround and constitute the hollow portion 14.

In some embodiments, the base 152 faces and conforms to the outer wall of the motor 30, and the raised structure 151 faces away from the motor 30. Because the cross-section of base 152 is great, and the cross-section of protruding structure 151 is less, if with base 152 laminating motor 30, protruding structure 151 butt exterior structure, then to the filtration of the vibration of motor 30 itself or noise, absorptive capacity is stronger, avoids transmitting to exterior structure. In some embodiments, the protruding structure 151 faces and abuts against the outer wall of the motor 30, the base portion 152 faces away from the motor 30 and is attached to the outer structure, the protruding structure 151 with a smaller cross-sectional area abuts against the motor 30, and the shock and vibration transmitted to the motor 30 from the outside are buffered. In a specific application, the protruding structure 151 faces away from the motor 30 (i.e., protrudes outward), or the protruding structure 151 faces toward the motor 30 (i.e., protrudes inward) may be selected according to actual needs.

In a specific embodiment, the convex structure 151 is cylindrical, the end is provided with a spherical structure which is easy to abut, the cylindrical supporting part bears force uniformly after being stressed, and the force can be evenly distributed and transmitted to the base part 152. The actual contact surface of the spherical structure is smaller, and the effect of reducing the contact area can be achieved.

As shown particularly in fig. 3, the radius R1 of the raised structure 151 (i.e., the radius of the cylindrical portion thereof) is less than or equal to the distance R2 between the edge of the raised structure 151 and the nearest edge of the base 152. From the equation of the circle area calculation, it can be seen that if the distance R2 between the base 152 and the nearest edge of the protrusion 151 is equal to or greater than the radius R1 of the protrusion 151 itself, the base 152 includes at least a region that is 4 times the cross-sectional area of the protrusion 151, and the protrusion 151 is located at the center of the region, so that the predetermined cushioning requirement can be satisfied. In other embodiments, the protruding structure 151 may have other shapes, such as a rectangle, a hexagon, etc., and accordingly, the corresponding base 152 covers a region four times its area according to the area definition, and the center of the protruding structure 151 substantially coincides with the center of the region to satisfy the predetermined cushioning requirement.

In some embodiments, as shown in fig. 2 and 4, the plurality of cushioning portions 15 are arranged to form a plurality of sets of cushioning modules, and the plurality of cushioning portions 15 in each set of cushioning modules are arranged along the axial direction of the cushioning structure 10. In the working process of the motor 30, the rotor and the stator are radially positioned only through the bearing, so that the limiting rigidity of the rotor in the axial direction is low, the play or vibration of the rotor in the axial direction is more obvious during rotation, and the high-frequency vibration is more severe on the motor 30, namely the high-frequency vibration in the axial direction. The plurality of buffer portions 15 are arranged in a plurality of rows at least in the radial direction, and the plurality of buffer portions 15 in each row are arranged substantially along the axial direction, so that the strength of the buffer structure 10 in the axial direction can be enhanced. If buffer 15 misplaces in the axial, can lead to buffer structure 10 not enough at the regional axial strength of dislocation set, when motor 30 axial vibration, the stroke that buffer structure 10 axial strength is not enough compressed is bigger, consequently leads to the whole orientation that is partial to axial strength low of motor 30 for motor 30 vibration is biased, enlargies, and the emergence that this problem can be avoided to the axial direction range of buffer structure 10 is all followed to a plurality of buffers 15 in each buffering subassembly.

In a more specific embodiment, each cushioning module has the same number of cushioning portions 15. The same number of buffer portions 15 means that the overall axial strength can be substantially the same, so that the axial strength provided by the plurality of buffer assemblies can be substantially the same, and further, the axial strength at each position of the buffer structure 10 can be substantially the same, thereby avoiding the problem of axial vibration deflection of the motor 30.

In a more specific embodiment, the multiple groups of buffer assemblies are uniformly arranged along the circumferential direction of the buffer structure 10, that is, on the radial cross section of the buffer structure 10, the multiple buffer parts 15 are substantially uniformly distributed along the edge, so that uniform force bearing in the circumferential direction is realized, and due to the fact that the multiple buffer parts 15 are arranged in the axial direction, uniform force bearing in the circumferential direction and uniform force bearing in the axial direction are realized, and the problem of axial vibration deviation of the motor 30 is further avoided.

In other embodiments, the plurality of cushioning portions 15 are arranged along the circumferential direction of the cushioning structure 10; and each of the base 152 and the projection 151 extends axially along the cushioning structure 10. That is, the base 152 and the raised structure 151 are each elongate elongated structures, rather than separate, discrete pluralities of structures. A plurality of buffer portions 15 are arranged along circumference, and each buffer portion 15 extends along the axial for intensity in the axis direction is great, and each intensity is the same roughly, and the mechanism of action is the same with aforementioned buffer assembly, can play equally to make buffer structure 10 axial load even, avoids the problem of motor 30 axial vibration deviation, and the principle is not repeated.

In practical applications, in order to avoid resonance with the motor 30, the number of rows of the buffer units 15 needs to be designed to be a specific number. The number of rows, i.e. the number of groups of cushioning elements in embodiments employing cushioning elements, or the number of cushioning portions 15 in embodiments employing axially extending cushioning portions 15. The motor 30 generally has a plurality of blades, and a plurality of cores are provided on the rotor or the stator, and the number of the rows needs to be different from the number of the blades and the number of the cores, so as to avoid resonance caused by one-to-one correspondence of the number of the blades. Further, in the case where the motor 30 is provided with a plurality of air guide blades, the number of rows needs to be different from the number of air guide blades. In addition, if the motor 30 has structures such as axial ribs, reinforcing ribs, etc., the number of rows should be avoided.

Cushioning structure 10 may be a unitary structure or may include a plurality of sub-structures. In a specific embodiment, as shown in fig. 1 to 6, the buffer structure 10 is an integral structure, and has a cavity 13 into which the motor 30 can be inserted and a buffer sidewall 11 for wrapping the motor 30, the plurality of buffer portions 15 and the plurality of hollow portions 14 are alternately and arrayed on the buffer sidewall 11, so that the buffer portions 15 and the hollow portions 14 are substantially uniformly distributed at each position on the buffer sidewall 11, and the motor 30 is inserted into the cavity 13 and then uniformly performs vibration isolation and noise reduction at each position of the motor 30 through the buffer portions 15 and the hollow portions 14 alternately and arrayed on the buffer sidewall 11.

Since the motor 30 is generally cylindrical, and the cavity 13 is generally cylindrical, it is easily understood that there also exists a non-cylindrical motor 30 in the prior art, such as a rectangular parallelepiped, a polygonal prism, etc., and the cavity 13 can be correspondingly configured to be non-cylindrical, and the specific shape is not the focus of the present embodiment, and the following description will take the motor 30 as a cylindrical shape as an example, unless otherwise specified.

In other embodiments, the buffer structure 10 may also be a split structure, including a plurality of relatively independent sub-structures, which together form a substantially barrel-shaped structure, and is sleeved and attached outside the motor 30. The substructures can be disconnected or mutually abutted, gaps are reserved at the joint to form hollow structures, or each substructure forms a plurality of hollow parts 14 through holes, gaps and the like; one or more buffer portions 15 may be formed on each substructure, or one or more buffer portions 15 may be formed by combining the substructures. In a specific embodiment, the sleeve 20 capable of accommodating the motor 30 is designed, a plurality of the above sub-structures are fixed on the inner wall of the sleeve 20 by gluing, thermoforming, embedding, magnetic attraction, etc. to form the buffer structure 10, and the buffer structure 10 is made to be capable of sleeving the motor 30 after the motor 30 is inserted into the sleeve 20. In another embodiment, the buffer structure 10 may be formed by adhering and fixing a plurality of the above sub-structures on the outer wall of the motor 30 by gluing, thermoforming, embedding, magnetic attraction, or the like.

As shown in fig. 1-6, in some embodiments, the cushioning structure 10 further includes a connecting portion 16 located between two adjacent cushioning portions 15, the connecting portion 16 being formed of a flexible material. The cushioning structure 10 has generally three configurations: the buffer structure comprises a buffer part 15, a hollow part 14 and a connecting part 16, wherein the connecting part 16 connects the buffer part 15 with each other, so that the buffer structure 10 is not divided into a plurality of independent parts by the hollow part 14, and the whole integral structure and shape can be kept. Since the connecting portion 16 is made of a flexible material, that is, the entire shock absorbing structure 10 actually takes on the tensile and compressive deformation actions of the connecting portion 16 when absorbing vibration, thereby performing the aforementioned vibration damping and noise reduction actions. It is understood that in other embodiments, the cushioning structure 10 may also include a plurality of sub-structures, and the cushioning portions 15 are connected by the connecting portions 16 inside the sub-structures, that is, the connecting portions 16 do not connect all the cushioning portions 15 into an integral structure.

In some embodiments, the connecting portion 16 may be a structure independent from the cushioning portion 15, for example, as shown in fig. 1 to 4, the plurality of connecting portions 16 include a plurality of rib structures extending in different directions, and at least a portion of the hollow portion 14 is formed by surrounding adjacent rib structures, that is, a structure extending in a substantially strip shape. In other embodiments, the shape may be one or more of a rectangular parallelepiped, a cylindrical shape, and a prismatic shape. After the rib structures are staggered, a plurality of hollowed-out portions 14 can be formed with the rib structures themselves and the staggered positions as boundaries. It will be readily understood that the hollowed-out portion 14 is not limited to a shape having a closed boundary, and may be a closed hole completely surrounded by a rib structure, for example, as shown in fig. 2, four sides of a rectangular hole are formed by four rib structures; the cutout 14 may also be an open hole formed by a rib structure, i.e. having at least one non-closed side (the cutout 14 is connected to the outside of the cushioning structure 10 such that it lacks an actual boundary), for example in the form of a notch, or an area between two parallel rib structures, etc. In one embodiment, the rib structures have the same width and/or length to ensure that the cushioning portions 15 and the cut-outs 14 are uniformly arrayed on the cushioning sidewall 11, and each portion of the cushioning sidewall 11 has substantially the same structural strength.

In a particular embodiment, the plurality of rib structures include a plurality of radial ribs parallel to the axial direction of the cushioning structure 10 and a plurality of weft ribs perpendicular to the radial rib direction; each hollow portion 14 is formed by two adjacent radial ribs and two adjacent weft ribs. The radial ribs and the latitudinal ribs are perpendicular to each other, and a plurality of approximately rectangular hollow parts 14 are regularly divided, so that the strength distribution of the whole buffer structure 10 is relatively uniform, and the radial ribs can bear axial elastic deformation, and the radial ribs can be combined with the above embodiment to be part of the reinforced axial strength of the buffer structure 10. In another embodiment, as shown in fig. 7, the cushioning structure 10a may be formed by interlacing rib structures inclined in different directions, and the hollow portions 14a formed correspondingly may have a diamond shape. Similarly, in other embodiments, the extending direction and shape of the rib structure are designed to form hollow parts with other shapes.

In some embodiments, there may be no distinct boundary between the cushioning portion 15 and the connecting portion 16, even though the cushioning portion 15 forms a part of the connecting portion 16. Such as the base portion 152 described above, is formed on the connecting portion 16. From the foregoing, the base portion 152 and the convex structure 151 have an area restriction relationship therebetween, and therefore, it can be understood that a portion on the connecting portion 16 satisfying the area restriction relationship with the convex structure 151 constitutes the base portion 152.

In some embodiments, the connecting portion 16 and the cushioning portion 15 may be formed by different structures, for example, the connecting portion 16 is made of a first flexible material with smaller rigidity, and the cushioning portion 15 is made of a second flexible material with larger rigidity, which are fixed to form the cushioning structure 10. The whole cushion structure 10 can also be integrally formed by a flexible material, that is, all parts of the whole cushion structure 10 are made of the same flexible material by injection molding or the like, so that the production cost is low. According to different adopted flexible materials, the whole body has different buffer strengths, which is not described in detail.

As shown in fig. 1 to 6, the shape of the hollow-out portion 14 may be one or more of a circle, an ellipse, a part of a circle, and a polygon. In some embodiments, only one cutout 14 may be provided. In some embodiments, the plurality of hollow portions 14 may have the same shape, or may be differently set to different shapes, the plurality of hollow portions 14 may be uniformly or non-uniformly arranged on the buffer structure 10, and the shape and arrangement of the hollow portions 14 may affect the overall and local strength of the buffer structure 10. In a specific embodiment, the differentiated hollow portions 14 are adopted, for example, when the motor 30 works, the vibration amplitude is larger at a certain angle, in order to optimize the overall dynamic balance of the motor 30, the buffer strength is increased at the certain angle, the hollow portions 14 can be differentially arranged from other areas at positions where the stretched amplitude is larger, for example, the hollow portions 14 with at least two different sizes are respectively arranged in the area and the other areas, or, in the manner of adopting the foregoing plurality of substructures, substructures with larger thickness or width are arranged in certain areas, so that the buffer structure 10 can provide different vibration isolation effects in different areas, so that in the work of the motor 30, a stronger buffer strength is provided in the direction where the vibration amplitude is larger, and the dynamic balance of the motor 30 is optimized.

As shown in fig. 1 to 5, in a specific embodiment, the motor 30 has a side wall, i.e., an outer circumferential surface of the housing in a radial direction of the motor 30, and an end portion, i.e., an end portion in an axial direction of the motor 30. The buffer structure 10 further includes a buffer end portion 12 formed along an end portion of the buffer sidewall 11 to extend toward the inside of the cavity 13, and the buffer end portion 12 is configured to abut against an end portion of the motor 30. After the buffer structure 10 is sleeved outside the motor 30, the buffer side wall 11 wraps the side wall of the motor 30 to limit the vibration of the motor 30 in the radial direction, the end part of the motor 30 abuts against the buffer end part 12 of the buffer structure 10 to limit the vibration of the motor 30 in the axial direction, and the end part of the motor 30 is prevented from being directly in hard contact with an external rigid structure, the buffer end part 12 can be made of a flexible material, or further, the buffer part 15 is also arranged on the buffer end part 12, and the buffer and vibration isolation effects of the buffer part 15 on the motor 30 are realized in the axial direction. More specifically, the buffer end portion 12 itself may constitute the base portion 152 of the buffer portion 15, on which one or more convex structures 151 are disposed, or a plurality of base portions 152 are disposed on the buffer end portion 12, on which the convex structures 151 are correspondingly disposed on the base portions 152, and so on.

More specifically, as shown in fig. 1 and 5, the buffer end 12 includes an annular end collar (not shown) having a complete, generally annularly extending structure that completely surrounds and covers the end of the motor 30. It will be readily appreciated that the motor 30 is generally cylindrical and thus has a generally circular end face and the end collars are correspondingly annular, and that motors 30 of special shapes exist in the prior art, e.g., end faces of rectangular, oval, etc., and the buffer end 12 is correspondingly shaped.

In another embodiment, the buffer end portion 12 may be a plurality of end protrusions spaced apart from each other, so that the rigidity of the buffer end portion 12 can be reduced and the buffer end portion can be easily deformed. The cushioning end 12 may be a flexible material to further enhance cushioning. Similar to the end collars described above, the plurality of end bosses may be spaced apart in a generally annular shape to accommodate the motor 30. The end portion protrusion may be directly formed in the same structure as the buffer portion 15, or a block structure may be provided and the buffer portion may be further formed on the block structure.

More specifically, the length of the buffer end portion 12 extending toward the inner cavity 13 is approximately equal to the thickness of the side wall of the motor 30, and on the premise of being completely abutted against the side wall of the motor 30, the buffer end portion is prevented from extending into the motor 30, interfering with an impeller or influencing airflow in an air duct.

In some embodiments, as shown in fig. 1 to 5, in the axial direction of the buffer structure 10, the buffer end portions 12 are respectively protruded from both ends of the buffer side wall 11 toward the inside of the cavity 13, and abut against the buffer structure 10 at two opposite positions and are axially positioned. The two buffer end portions 12 may have the same size and structure, or may be designed into different shapes according to actual size or buffer requirements.

As shown in fig. 4 and 5, in some embodiments, the mount 100 further includes a sleeve 20, the sleeve 20 having an inner cavity for receiving the cushioning structure 10, i.e., the motor 30 is enclosed within the cushioning structure 10 and is wrapped by the cushioning structure 10, and the cushioning structure 10 is enclosed within the sleeve 20 and is wrapped by the sleeve 20. The sleeve 20 is a rigid structure that can be rigidly secured directly to an external structure, thereby securing the motor 30. In other words, the sleeve 20 replaces the housing of the motor 30 itself, and as a part actually rigidly fixed to the external structure, the vibration and noise transmitted between the sleeve 20 and the motor 30 are absorbed by the buffer structure 10, so that the sleeve 20 does not receive the vibration and noise from the motor 30, and the motor 30 does not receive the impact from the sleeve 20.

In some embodiments, an opening (not shown) is formed in the sleeve 20 to expose at least a portion of the at least one opening 14. After the motor 30 is mounted to the sleeve 20, although there is actually a two-layer structure surrounding the motor 30: the buffer structure 10 of the inner layer and the sleeve 20 of the outer layer, but the opening on the sleeve 20 can expose at least part of at least one hollowed-out portion 14, so that part of the motor 30 can be directly exposed from the sleeve 20, and when a grounding circuit needs to be arranged, the related electrical structure 31, such as a lead, a PCB and other structures, is connected to the motor 30 through the opening on the sleeve 20, which is convenient and fast. In order to increase the conductive area between the ground circuit and the motor 30, a copper foil may be attached to the housing of the motor 30, the copper foil and the housing of the motor 30 are fixed by gluing, etc., and the copper foil is exposed in the opening, so that the electrical structure 31 is electrically connected to the copper foil, i.e., electrically connected to the motor 30 and has a larger electrical contact area. Electrical structure 31 may be directly radially extended to facilitate an overall structural design. The left and right of the opening formed in the sleeve 20 are not limited to the electrical structure 31, but may also have other functions, such as exposing a nameplate, a two-dimensional code, etc. of the motor 30, so that a user can directly observe the nameplate, the two-dimensional code, etc. of the motor 30 even after the sleeve 20 is received therein, and can know information such as the type, lot, performance, etc. of the motor 30. The above technical effect cannot be achieved without any structure of the opening or the hollowed-out portion 14.

In some embodiments, as shown in fig. 5, a positioning structure 21 is protruded inside the sleeve 20, and the positioning structure 21 can be abutted by the buffer structure 10 and axially positioned, so as to prevent the buffer structure 10 from being displaced relative to the sleeve 20 as a whole, which causes the motor 30 to shake and impact the sleeve 20. Further, the sleeve 20 and the buffer structure 10 positioned with each other cannot be displaced relative to each other, so that the buffer structure 10 can only buffer and absorb vibration by self-deformation when the motor 30 vibrates, and cannot be displaced as a whole, thereby failing to deform and absorb vibration.

More specifically, as shown in fig. 4 to 6, the positioning structure 21 includes a rib 21 protruding toward the inside along the sleeve 20, and the buffer structure 10 is axially abutted to the rib 21. The ribs 21 allow the cushioning structure 10 to abut and be positioned. In one particular embodiment, in combination with the foregoing, the cushioning structure 10 has a cushioning end 12, the cushioning end 12 abutting the ledge 21 for axial positioning. That is, after the motor 30 is installed in the mounting member 10, the end portion of the motor 30 and the rib 21 are flexibly spaced by the buffering end portion 12, so that the end portion of the motor 30 is prevented from being directly contacted with the sleeve 20 to transmit vibration and noise, and therefore the whole motor 30 and each external position are flexibly abutted to each other, and the problem of vibration and noise transmission caused by rigid contact is thoroughly isolated. In other embodiments, the positioning structure 21 may also be a plurality of protrusions spaced apart from each other, a bolt mounted to the sleeve 20, and the like, and is not limited to the above-mentioned ribs 21.

In addition, because motor 30, sleeve 20 are the stereoplasm structure, consequently sleeve 20, buffer structure 10, the motor 30 three that establish in proper order can carry out the pre-compaction of certain degree to buffer structure 10 under the prerequisite of realizing axial positioning through relevant structure, size cooperation design to further promote the stability of motor 30 operation in-process, avoid leading to having the clearance to make motor 30 rock scheduling problem because of the assembly size relation.

In some embodiments, as shown in fig. 2-7, a motor 30 is disposed in the airflow path to accelerate the air to form an airflow after rotation. In order to avoid the air flow entering the area between the motor 30 and the sleeve 20, a sealing ring 18 is also arranged outside the buffer structure 10, and the sealing ring 18 protrudes outwards relative to the buffer structure 10 and can abut against the inner wall of the sleeve 20, so as to seal and avoid the formation of an air flow channel. The number of the sealing rings 18 may be plural, for example, one sealing ring may be provided at each of the positions near both ends of the cushion structure 18. In some embodiments, the sealing ring 18 constitutes the aforementioned raised structure 151, which itself also serves as a deformation buffer. In some embodiments, the sealing ring 18 is formed by the aforementioned raised structures 151, i.e., there is at least one raised structure 151 disposed to extend along the outer peripheral surface of the cushioning structure 18. In some embodiments, the sealing ring 18 may be formed by the connection portion 16 protruding outward. In some embodiments, the sealing ring 18 is not integral with the buffer structure 10, and can be a separate structure, which is sleeved outside the buffer structure 10, or a structure formed and fixed on the inner wall of the sleeve 20. For the same purpose, the buffer end 12 of the buffer structure 10 may be provided with a related sealing structure, or the axial length of the buffer structure 10 may be set to exceed the axial length of the inner cavity of the sleeve 20, so that the end is tightly sealed against the sleeve 20 due to axial compression after installation, and further, a related axial elastic structure may be provided to further increase the axial elasticity.

In some embodiments, as shown in fig. 1 to 6, the sleeve 20 is provided with a first positioning structure 22, and the buffer structure 10 is provided with a second positioning structure 17 for matching the first positioning structure 22 to realize circumferential positioning. Most of the existing motors 30 are cylindrical, the corresponding buffer structures 10 and the corresponding sleeves 20 are also cylindrical, when the buffer structures 10 are sleeved outside the motors 30 and the corresponding sleeves 20 are sleeved outside the buffer structures 10, if only axial positioning is carried out, the possibility of relative rotation exists among the three, especially when the motors 30 work, the motors have a tendency of rotation due to the reaction force of rotors, and the problem of related structure dislocation caused by the rotation of the shafts of the motors 30 easily occurs. In order to avoid this problem, the second positioning structure 17 is disposed on the buffer structure 10, and cooperates with the first positioning structure 22 to achieve positioning between the buffer structure 10 and the sleeve 20, so that the two do not rotate relatively when the motor 30 works, and can be quickly positioned circumferentially during assembly to ensure that the buffer structure is mounted to a preset state, thereby avoiding the possibility that the opening on the sleeve 20 is not opposite to the corresponding hollow portion 14 on the buffer structure 10. The buffer structure 10 is tightly attached to the motor 20, and the buffer structure and the motor can be positioned through friction force without a related circumferential positioning structure.

More specifically, the second positioning structure 17 is a positioning protrusion 17 protruding outward along the buffering structure 10, and the first positioning structure 22 is a positioning notch 22 formed on the sleeve 20 for inserting the positioning protrusion 17. During assembly, the buffer structure 10 is rotated to align the positioning protrusion 17 with the positioning notch 22, and after insertion, the two are clamped and positioned with each other, so that the buffer structure 10 and the sleeve 20 cannot rotate relatively. In other embodiments, other positioning methods may be used, for example, the first positioning structure and the second positioning structure are both bumps, and the first positioning structure and the second positioning structure are abutted against each other to realize positioning.

In some embodiments, the electric machine 30 has an electrical structure 31 (which may be the structure described above for grounding or the structure described above for inputting power or control signals to the electric machine 30) extending radially outward, and the electrical structure 31 passes through the positioning notch 22. The positioning notch 22 is a notch formed on the sleeve 20, and can be connected with the inside and the outside of the sleeve 20, the depth of the positioning notch 22 is deepened and exceeds the length of the positioning bump 17, after the positioning bump 17 is inserted into the positioning notch 22, a space is still left at the bottom of the positioning notch 22 to form a channel communicated with the inside of the sleeve 20, the electrical structure 31 is designed to be led out from the channel to be connected with the outside, and the motor 30 and the sleeve 20 can be mutually positioned by means of the electrical structure 31.

In the preferred embodiment, the bottom of the positioning projection 17 facing the positioning notch 22 defines, in the orientation shown in fig. 6, its lower end, at which there is provided a secondary limit notch 171 through which the electrical structure 31 can at least partially pass. After the electrical structure 31 passes through the positioning notch 22, the lower end thereof is located in the positioning notch 22, and the upper end thereof is located in the auxiliary limiting notch 171, so that the buffer structure 10, the electrical structure 31, and the sleeve 20 are mutually positioned.

In some embodiments, a buffer may also be disposed within the secondary retention notches 171 that abuts the electrical structure 31. In the process of operating the motor 30, the electrical structure 31 rigidly connected to the motor 30 also serves as a way for transmitting energy, and therefore, the buffer part is disposed in the auxiliary limit notch 171 and abuts against the electrical structure 31 to elastically pre-compress the electrical structure 31, so that the vibration energy of the electrical structure 31 can be absorbed, and the vibration and noise can be prevented from being transmitted to the outside through the electrical structure 31.

As shown in fig. 8, there is also provided in an embodiment of the present application an electrical device 200 comprising a housing 60, a mounting member and a motor 30, the housing 60 being provided with an airflow outlet 50, the mounting member not being shown in fig. 8 for clarity of illustrating the structural arrangement of the electrical device 200, the position of which can be understood with reference to the motor 30. The motor 30 is mounted within the housing 60 and is capable of generating an airflow that exits the housing 60 from the airflow outlet 50 to act on a target. The motor 30 is buffered by the mounting member while operating, so that vibration and noise are not transmitted to the housing 60, and further, when the housing 60 is impacted or dropped, the impact force is buffered by the mounting member and is not transmitted to the motor 30. For the related technical effects and principles of the mounting member itself, please refer to the foregoing.

In a specific embodiment, the electrical device 200 further comprises a radiation source 40, the radiation source 40 being an electrical device capable of generating infrared radiation. When the electrical equipment 200 works, the infrared radiation and the air flow can jointly act on an external target object, and the drying efficiency is improved.

In some embodiments, the radiation source 40 has a through gas flow channel therein, one end of the gas flow channel is correspondingly connected to the gas flow outlet 50, and the other end of the gas flow channel is connected to the motor 30. In a more specific embodiment, the mounting member may be directly fixed to the radiation source 40 at a position where the air flow path is provided, thereby indirectly fixing the motor 30 to the housing 60.

In some embodiments, in addition to the radiation source 40 described above, a secondary heat source 70 may be provided inside the electrical device 200 for directly heating the airflow. The secondary heat source 70 may be located at least partially upstream of the motor 30, i.e., the air is heated prior to accelerating the heated air to form a hot air stream. Alternatively, the radiation source 70 may be located at least partially downstream of the motor 30, i.e., the air is accelerated prior to heating the high velocity air stream to form a heated air stream.
