Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to a shock-absorbing pad, a motor mounting structure, and an air conditioner. Background Technology

[0002] In current air conditioning equipment and its installation components, most motors have built-in mounting brackets and are fixed to the load equipment using shock-absorbing rubber rings and bolts. However, the mounting feet of encapsulated motors, metal end caps, or welded brackets currently have a single, fixed installation size, which is quite limiting. When dealing with different load equipment from various manufacturers and models with similar performance requirements, even slight deviations in the overall installation size can lead to motor incompatibility. This necessitates the creation of new molds for the motor encapsulation or shock-absorbing rubber rings (i.e., damping pads), resulting in significant waste in production costs. Furthermore, adjustments to the motor mounting foot structure due to installation size constraints not only waste design costs but also severely impact new product development and project development cycles. Utility Model Content

[0003] Therefore, this utility model provides a shock-absorbing pad, a motor mounting structure, and an air conditioner, which can overcome the technical problems of poor structural design versatility of shock-absorbing pads in related technologies, making it difficult to apply the shock-absorbing pad when there are small deviations in the mounting holes of the motor support or mounting carrier, resulting in high design and production costs.

[0004] To solve the above problems, this utility model provides a shock-absorbing pad, including a shock-absorbing pad body. The shock-absorbing pad body has a first end face and a second end face in its supporting direction. The shock-absorbing pad body has a bolt through hole that passes through the first end face and the second end face. Projected on the first end face, the bolt through hole has a U-shaped portion, and the radial depth of the U-shape is greater than the width of the U-shape.

[0005] In some embodiments, the shock-absorbing pad body includes an upper support body, a middle connecting body, and a lower support body that are sequentially connected along the support direction. The outer wall of the middle connecting body is formed with a slot. The slot is configured to pass through the bolt and its projection on the first end face is U-shaped. The slot can be engaged with the upper and lower slot surfaces of the U-shaped groove of the motor's support leg.

[0006] In some embodiments, a plurality of shock-absorbing ribs are formed on the groove wall surface of the card slot, and the shock-absorbing ribs are arranged at intervals.

[0007] In some embodiments, the central connecting body is further provided with multiple stress buffer grooves.

[0008] In some embodiments, each of the stress buffer grooves is spaced apart around the bolted member through hole; and / or, each of the stress buffer grooves extends to the first end face or the second end face.

[0009] This utility model also provides a motor mounting structure, including a motor, wherein each of the motor's legs has a U-groove in which the aforementioned shock-absorbing pad is provided, and the symmetrical center plane of the U-groove coincides with the symmetrical center plane of the U-shaped portion of the through hole of the bolt member.

[0010] In some embodiments, a clearance groove is formed on the support leg corresponding to the top surface area of ​​the U-groove, and a support platform is formed between the clearance groove and the U-groove, with the bottom end face of the upper support body supported on the support platform.

[0011] In some embodiments, the motor mounting structure further includes a mounting carrier and a bolting member. The bolting member includes a column passing through a through hole in the bolting member. The first end of the column has a connecting plate for connecting with the mounting carrier. The second end of the column protruding from the first end face has a nut threadedly connected to the column section. When the shock-absorbing pad is provided with a stress buffer groove and the shock-absorbing pad and the support leg are assembled in a shock-absorbing support state, the width of the stress buffer groove in the inner and outer wall thickness direction of the shock-absorbing pad body is k, and the axial compression of the shock-absorbing pad body is q, where q < k.

[0012] In some embodiments, the connecting plate is located on the side of the mounting carrier away from the motor, and a plurality of riveting protrusions are formed on the end face of the connecting plate near the mounting carrier.

[0013] This utility model also provides an air conditioner, including the motor mounting structure described above.

[0014] The shock-absorbing pad, motor mounting structure, and air conditioner provided by this utility model have the following beneficial effects:

[0015] Unlike existing rotary column structure shock absorbers (also known as shock absorber rings) with a circular bolt hole at the center, the shock absorber in this invention has a U-shaped bolt hole on its body, with the depth of the U greater than its width. This allows the shock absorber to have a greater displacement compensation distance in the radial direction of the motor, making it suitable for motors of different diameters within a certain range and for different mounting hole diameters on the mounting carrier. This improves the structural versatility of the shock absorber. Therefore, even if there are dimensional deviations between the motor and the mounting carrier (within a certain range), there is no need to design changes to the motor or mounting carrier structure specifically to address these deviations, nor is it necessary to separately mold and manufacture shock absorbers of suitable dimensions, thus reducing design and production costs.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0031] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0032] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0033] See also Figures 1 to 10 As shown, according to an embodiment of the present invention, a shock-absorbing pad is provided, including a shock-absorbing pad body 1, wherein the shock-absorbing pad body 1 has a direction in which it supports (e.g., Figure 1 The first end face (not labeled in the figure) and the second end face (not labeled in the figure) on the axial direction are shown, with Figure 1 The orientation shown is for reference. The aforementioned first end face is the top end face of the shock-absorbing pad body 1, and the second end face is the bottom end face of the shock-absorbing pad body 1. The shock-absorbing pad body 1 has a bolting through hole 11 that passes through the first end face and the second end face. Projected on the first end face, the bolting through hole 11 has a U-shaped portion, and the radial depth of the U-shape (i.e., with...) Figure 1 The direction perpendicular to the plane formed by the axial direction and the width direction of the U-shape (that is, the radial direction of the motor 100 after it is assembled with the motor 100) is greater than the width of the U-shape (see [reference]). Figure 1 As shown), in a specific embodiment, the aforementioned bolt hole 11 is as follows: Figure 1 In some other feasible embodiments, the U-shaped opening groove shown can also be a racetrack-shaped through groove (also called a waist-shaped groove).

[0034] In this technical solution, unlike the existing technology where the rotating column structure of the shock-absorbing pad (also known as the shock-absorbing rubber ring) has a circular bolt hole at the center, the bolt hole 11 on the shock-absorbing pad body 1 of this utility model has a U-shaped portion and the depth of the U is greater than the width of the U. This allows the shock-absorbing pad to have a larger displacement compensation distance in the radial direction of the motor 100, and can adapt to motors 100 of different diameters within a certain range and different mounting hole distribution circle diameters on the mounting carrier 200. This improves the structural versatility of the shock-absorbing pad. Thus, when there is a deviation in the installation dimensions between the motor and the mounting carrier (within a certain range), it is not necessary to design changes to the structure of the motor or the mounting carrier separately to address this deviation, nor is it necessary to separately mold and prepare shock-absorbing pads of suitable size, thereby reducing design and production costs.

[0035] See also Figure 1 and Figure 2As shown, in some embodiments, the shock-absorbing pad body 1 includes an upper support body 121, a middle connector 122, and a lower support body 123 connected sequentially along the support direction. The outer wall of the middle connector 122 has a slot 1221. The slot 1221 is arranged around the bolt hole 11 and its projection on the first end face is U-shaped. The slot 1221 can be engaged with the upper and lower slots of the U-groove of the motor's support leg 101. The upper and lower slots are the portions of the support leg 101 facing the first end face and the second end face, respectively, located in the U-groove position.

[0036] In this technical solution, the damping pad body 1 is divided into three parts connected from top to bottom: an upper support body 121, a middle connecting body 122, and a lower support body 123. The upper support body 121 and the lower support body 123 cooperate with the fastening components at the upper and lower ends of the bolt 2 (such as the connecting disc 22 and nut 23 mentioned later) to limit the damping pad body 1 in the axial direction. The middle connecting body 122 forms an axial support cooperation with the upper and lower slot surfaces of the U-shaped groove of the support leg 101 through the upper and lower limiting platform (not marked in the figure) formed by the aforementioned U-shaped slot 1221. This effectively realizes the purpose of damping connection between the support leg 101 of the motor 100 and the mounting carrier 200 through the damping pad body 1 with damping function. It is understood that at least three of the aforementioned support legs 101 are generally provided. The at least three aforementioned support legs 101 are evenly spaced around the rotating shaft of the motor 100. The aforementioned shock-absorbing pads and bolts 2 assembled on each support leg 101 can form a centered (aligned) installation of the motor 100. That is, no matter where the bolts 2 are located in the radial direction of the aforementioned U-shaped bolt through hole 11, reliable shock-absorbing support for the motor 100 can be achieved.

[0037] In some embodiments, a plurality of shock-absorbing buffer ribs 1222 are formed on the groove wall surface of the slot 1221, and the shock-absorbing buffer ribs 1222 are arranged at intervals. In a specific embodiment, the aforementioned shock-absorbing buffer ribs 1222 are arranged at intervals along the axial direction of the shock-absorbing pad body 1.

[0038] In this technical solution, on the one hand, by setting shock-absorbing buffer ribs 1222 on the groove wall of the slot 1221, the contact area between the slot 1221 and the support leg 101 can be reduced. At the same time, each shock-absorbing buffer rib 1222 also has a certain deformation capacity, which can further reduce the degree of transmission from the motor 100 to the mounting carrier 200 through the shock-absorbing pad body 1, thereby reducing the noise level. On the other hand, each shock-absorbing buffer rib 1222 can connect the upper support body 121 to the lower support body 123, improving the toughness and strength of the middle connecting body 122. It is understood that when the shock-absorbing pad is assembled in the U-groove of each support leg 101, each shock-absorbing buffer rib 1222 is clamped between the vertical wall of the U-groove of the support leg 101 and the vertical wall of the slot 1221.

[0039] In some embodiments, the central connector 122 is further provided with a plurality of stress buffer grooves 1223. Specifically, each stress buffer groove 1223 is arranged at intervals around the bolt through hole 11.

[0040] In this technical solution, the transmission of tangential vibration of the support leg 101 can be further reduced and the noise level can be reduced by multiple stress buffer grooves 1223 that are spaced around the bolt hole 11 and located in the middle connector 122.

[0041] To facilitate the fabrication of each stress buffer groove 1223, each stress buffer groove 1223 extends through to the first end face or the second end face.

[0042] See also Figures 4 to 10 As shown, according to an embodiment of the present invention, a motor mounting structure is also provided, including a motor 100. Each support leg 101 of the motor 100 has a U-groove in which the above-mentioned shock-absorbing pad is provided, and the symmetrical center plane of the U-groove coincides with the symmetrical center plane of the U-shaped portion of the through hole 11 of the bolt. A fan blade 300 is connected to the output shaft of the motor 100.

[0043] See details Figure 5 As shown, in some embodiments, a clearance groove 102 is formed on the support leg 101 corresponding to the top surface area of ​​the U-groove. A support platform 103 is formed between the clearance groove 102 and the U-groove. The bottom end face of the upper support body 121 is supported on the support platform 103. The radius of the aforementioned clearance groove 102 is a, which should be larger than the maximum outer diameter of the nut 23 of the bolt 2 to prevent the bolt 2 from contacting the support leg 101, causing a short circuit and loss of the damping function.

[0044] In some embodiments, the motor mounting structure further includes a mounting carrier 200 and a bolting member 2. The bolting member 2 includes a column 21 passing through the bolting member through hole 11. The first end of the column 21 has a connecting plate 22 for connecting with the mounting carrier 200. The second end of the column 21 protrudes from the column section of the first end face and is threaded with a nut 23. A limiting ring platform 211 is formed on the second end of the column 21 to axially limit the nut 23. The length of the column 21 between the limiting ring platform 211 and the connecting plate 22 is n. The total height of the damping pad body 1 is h. When the damping pad is provided with a stress buffer groove 1223 and the damping pad is assembled with the support leg 101 in a damping support state, the width of the stress buffer groove 1223 in the inner and outer wall thickness direction (i.e., the width direction or radial direction) of the damping pad body 1 is k. The axial compression of the damping pad body 1 is q, q < k, and the aforementioned q = hn.

[0045] In this technical solution, the axial compression amount, i.e. the axial deformation amount q, of the shock-absorbing pad body 1 is limited to be less than the width k of the stress buffer groove 1223 in the radial or thickness direction. This can prevent the groove walls on both sides of the stress buffer groove 1223 from contacting and reducing its stress buffering effect when the shock-absorbing pad body 1 is in a supported state.

[0046] In one specific embodiment, the aforementioned nut 23 is a washer nut, which can reduce the amount of material.

[0047] In some embodiments, the connecting disc 22 is located on the side of the mounting carrier 200 facing away from the motor 100. Multiple riveting protrusions 221 are formed on the end face of the connecting disc 22 near the mounting carrier 200. It is understood that the mounting carrier 200 has corresponding grooves at corresponding positions for each of the aforementioned riveting protrusions 221, with each protrusion 221 riveted into its respective groove. This reliably limits the circumferential displacement of the bolted member 2 and improves the bonding force between the connecting disc 22 and the mounting carrier 200, ensuring reliable connection. It is understood that q = hns, where s is the wall thickness of the mounting carrier 200 corresponding to the position of the bolted member 2. At this time, when the shock absorber is in working state (i.e., the aforementioned support state), the nut 23, the shock absorber body 1, the mounting carrier 200, and the connecting plate 22 are connected as a whole along the axial direction of the column 21, while the support leg 101 of the motor 100 is clamped and limited in the slot 1221 of the middle connecting body 122 of the shock absorber body 1.

[0048] See also Figure 3 , Figure 5 , Figure 6 and Figure 9As mentioned above, the width of the stress buffer groove 1223 is k, and the height is j, defined as 0 < k < m, 0 < i < j < h, where m is the radial thickness of the middle connecting body 122, h is the total height (axial) of the shock-absorbing pad body 1, and i is the axial height of the middle connecting body 122. The width of the upper support body 121 is e, the width of the lower support body 123 is d, the width of the middle connecting body 122 is f, the width of the bolt through hole 11 is g, 0 < g < f < e < a, the width of the support platform of the support leg 101 is b, the height is c, the slope of the support leg 101 is α, defined as 0 < α < 90°, b = f, c = i, and the diameter of the aforementioned main body 21 is p, p = g.

[0049] The material of the aforementioned shock-absorbing pad body 1 is preferably rubber, which mainly includes four steps: rubber raw material collection, rubber preparation, mixing and molding.

[0050] According to an embodiment of the present invention, an air conditioner is also provided, including the motor mounting structure described above. Specifically, the air conditioner is a ceiling-mounted unit, and the mounting carrier 200 is specifically the top shell of the ceiling-mounted unit.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
