Abstract
Description
Technical Field
[0001] This application relates to the field of compressor technology, specifically to a support device for a compressor, a compressor assembly, and a household appliance. Background Technology
[0002] Currently, the compressor is the main source of vibration in air conditioners. Foot pads are usually installed between the compressor and the air conditioner chassis to support the compressor and reduce the transmission of compressor vibration to the air conditioning system, thereby reducing the vibration noise of the air conditioner.
[0003] Related technology provides a support assembly for a compressor. The support assembly includes a foot pad, a sleeve, and fasteners. The outer wall of the foot pad has at least one annular groove and an axially penetrating mounting hole. The inner wall of the mounting hole has an inwardly extending limiting protrusion. The sleeve extends into the mounting hole and engages with the limiting protrusion. The mounting hole has a radial clearance with the sleeve above and / or below the limiting protrusion. The fastener passes through the sleeve. The compressor foot has a radial clearance with the sleeve above the limiting protrusion. By leaving a certain radial clearance between the sleeve and the mounting hole, when vibration is transmitted to the support assembly, the radial clearance can increase the radial deformation of the foot pad. Furthermore, the annular groove reduces the axial stiffness of the foot pad, which can increase the axial deformation of the foot pad and improve the vibration isolation capability of the support assembly.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] In related technologies, the limiting protrusion can limit the horizontal movement of the sleeve, and the compressor feet have a radial clearance between themselves and the sleeve above the limiting protrusion. Although the radial clearance can dampen vibration, during compressor vibration, the feet drive the foot pads to move radially, and the sleeve will directly impact the inner wall of the through hole, generating a large vibration impact and affecting the stability of the compressor.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

The protruding part bends and deforms when mating with the fastener, reducing the radial stiffness of the support device and improving its vibration damping and isolation effect. Simultaneously, because the protruding part protrudes from the inner circumferential wall of the first through hole, a gap is formed between the inner circumferential wall of the first through hole and the fastener, providing a buffer space and enhancing the vibration isolation effect. Therefore, by providing a protruding part on the inner circumferential wall of the first through hole, the vibration damping effect of the support device can be improved while simultaneously enhancing the compressor's operational stability.

[0056] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0057] A compressor is a rotating machine, and the vibration it produces can be divided into circumferential vibration, radial vibration and axial vibration, with circumferential vibration being the most common.
[0058] The support device is fixed by a screw engaging with a through hole. When the support device is subjected to radial force, the inner wall of the through hole typically contacts the screw to resist deformation. Therefore, the radial stiffness of the support device is determined by the amount of compression between the outer and inner walls of the through hole, similar to compression deformation, resulting in high radial stiffness. Since the compressor's main vibration is circumferential, high radial stiffness of the support device leads to poor vibration damping and isolation for the compressor's circumferential vibration.
[0059] The vibration reduction and isolation effect of a support device is usually measured using vibration transmissibility; a lower vibration transmissibility indicates better vibration isolation. Vibration transmissibility is positively correlated with the stiffness of the support device; the lower the stiffness, the lower the transmissibility. Therefore, from a vibration isolation perspective, the lower the stiffness of the support device, the better. However, excessively low stiffness can lead to insufficient support for the compressor. Based on the installation characteristics of the support device and the compressor, the stiffness of the support device can be divided into radial stiffness and axial stiffness. Radial stiffness is mainly used to isolate the circumferential and radial vibrations of the compressor, while axial stiffness is mainly used to support the compressor and isolate its axial vibrations. Since the compressor's main vibration is circumferential, it is necessary to increase the axial stiffness while reducing the radial stiffness of the support device.
[0060] Combination Figure 1-4As shown, this embodiment of the present disclosure provides a support device 20 for a compressor 10. The compressor 10 is provided with support legs 11. The support device 20 is connected to a preset mounting surface 40 by fasteners 30. The support device 20 includes a mounting pad 21 and a support pad 26.
[0061] Combination Figure 1-3 As shown, the mounting pad 21 has a first through hole 22 along the axial direction of the support device 20. The mounting pad 21 includes a mounting part 23 and a protruding part 24. The mounting part 23 is located on the outer peripheral wall of the first through hole 22 and is used to mount the support leg 11 of the compressor 10. The protruding part 24 protrudes from the inner peripheral wall of the first through hole 22 and is configured to bend and deform under external force. The fastener 30 is adapted to pass through the first through hole 22 and cooperate with the protruding part 24.
[0062] The axial direction of the support device 20 is as follows Figure 2 As indicated by the middle arrow.
[0063] The direction of the compressor's vibration force is as follows Figure 3-4 As shown. Figure 4 As shown, the fastener 30 passes through the first through hole 22 and cooperates with the protrusion 24. When the mounting part 23 is subjected to the vibration force of the compressor 10, it bends and deforms along the axial direction of the support device 20.
[0064] The mounting part 23 is located on the outer peripheral wall of the first through hole 22 and directly engages with the support leg 11 of the compressor 10, ensuring stable installation between the compressor 10 and the support device 20. The protruding part 24 protrudes from the inner peripheral wall of the first through hole 22, converting the radial stiffness of the mounting pad 21 from the compressive deformation of the inner peripheral wall of the first through hole 22 into the bending deformation of the protruding part 24. The radial stiffness of the support device 20 is primarily determined by the bending deformation of the protruding part 24. The fastener 30 passes through the first through hole 22. When the compressor 10 vibrates during operation, the outer wall of the fastener 30 first contacts the protruding part 24. The protruding part 24 bends under external force, reducing the radial stiffness of the support device 20 and effectively improving the vibration damping and isolation effect of the support device 20 on the circumferential vibration of the compressor 10.
[0065] The fastener 30 passes through the first through hole 22. When not subjected to external force, the protrusion 24 and the fastener 30 can either abut against each other or have a certain gap. When the compressor 10 vibrates during operation, the fastener 30 abuts against the protrusion 24, causing the protrusion 24 to bend and deform. The fastener 30 can be a screw.
[0066] Using the support device 20 for the compressor 10 provided in this embodiment, when the compressor 10 experiences circumferential or radial vibration, the support leg 11 transmits the vibration force to the mounting portion 23. During vibration, the protrusion 24 of the mounting pad 21 first contacts the fastener 30, preventing the fastener 30 from directly impacting the inner peripheral wall of the first through hole 22, thereby avoiding abrupt changes in radial stiffness. The protrusion 24 bends and deforms when engaging with the fastener 30, reducing the radial stiffness of the support device 20 and improving its vibration damping and isolation effect. Simultaneously, since the protrusion 24 protrudes from the inner peripheral wall of the first through hole 22, a gap is formed between the inner peripheral wall of the first through hole 22 and the fastener 30, providing a buffer space and increasing the vibration isolation effect. Therefore, by providing the protrusion 24 on the inner peripheral wall of the first through hole 22, the vibration damping effect of the support device 20 can be improved while simultaneously enhancing the operational stability of the compressor 10.
[0067] Optionally, the protrusion 24 is provided at the end of the mounting portion 23 along the axial direction of the support device 20.
[0068] The support leg is installed on the mounting part 23, and the extension part 24 is provided at the end of the mounting part 23 along the axial direction of the support device 20, which can better reduce the radial stiffness of the support device 20.
[0069] Optionally, combined Figure 2 As shown, the protrusion 24 forms a mating space 241 along the radial direction of the first through hole 22 to mate with the fastener 30. The radial dimension of the mating space 241 is larger than the outer diameter of the fastener 30.
[0070] The radial dimension of the mating space 241 is larger than the outer diameter of the fastener 30, which can reduce the friction when the fastener 30 is inserted, reduce the installation difficulty and the required installation force.
[0071] Optionally, combined Figure 1-3 As shown, the protrusion 24 extends in a ring shape along the circumference of the first through hole 22, and a mating space 241 is formed inside the ring protrusion 24. The fastener 30 is adapted to pass through the mating space 241.
[0072] The protrusion 24 extends annularly along the circumference of the first through hole 22, maintaining the continuity of the protrusion 24 and providing a larger bending deformation area, thereby achieving better vibration reduction when the fastener 30 is inserted. The annular protrusion 24 can also evenly distribute the force applied by the fastener 30, reducing local stress concentration and improving the durability and reliability of the support device 20.
[0073] It is understood that the protrusion 24 may include a first protruding section and a second protruding section arranged radially symmetrically along the first through hole 22, with a mating space formed between the first protruding section and the second protruding section, and the fastener 30 is adapted to pass through the mating space and symmetrically mate with the first protruding section and the second protruding section.
[0074] The first mating section 272 and the second mating section 272, which are symmetrically arranged radially along the first through hole 22, can provide symmetrical mating points for the fastener 30, thereby more effectively reducing radial stiffness and improving the stability of the mating between the support device 20 and the fastener 30.
[0075] Optionally, combined Figure 4 As shown, the mounting portion 23 includes a first end 231 and a second end 232 opposite to each other along the axial direction of the support device, and the number of protrusions 24 is multiple, including a first protrusion 242 and a second protrusion 243; the first protrusion 242 is disposed at the first end 231 of the mounting portion 23 along the axial direction of the support device; the second protrusion 243 is disposed at the second end 232 of the mounting portion 23 along the axial direction of the support device.
[0076] The first protrusion 242 and the second protrusion 243 can cooperate with the fastener 30 in different areas of the mounting pad 21 to achieve bending deformation, effectively reducing the radial stiffness of the support device 20. The first protrusion 242 and the second protrusion 243 are respectively provided at the first end 231 and the second end 232 of the mounting part 23, which are arranged opposite each other along the axial direction of the support device. The support leg 11 of the compressor 10 is mounted on the mounting part 23. When the compressor 10 vibrates, the first protrusion 242 and the second protrusion 243 can form a better vibration damping effect at the first end 231 and the second end 232 of the mounting part 23.
[0077] Optionally, the first protrusion 242 forms a first mating space along the radial direction of the first through hole 22 to mate with the fastener 30, the radial dimension of the first mating space being larger than the outer diameter of the fastener 30; and / or, the second protrusion 243 forms a second mating space along the radial direction of the first through hole 22 to mate with the fastener 30, the radial dimension of the second mating space being larger than the outer diameter of the fastener 30. This facilitates the installation of the fastener 30.
[0078] It is understandable that only one of the first extension 242 and the second extension 243 can be provided.
[0079] like Figure 4 As shown, the fastener 30 passes through the first through hole 22 and cooperates with the first protrusion 242 and the second protrusion 243. When the mounting part 23 is subjected to the vibration force of the compressor 10, the first protrusion 242 bends upward along the axis of the support device 20, and the second protrusion 243 bends downward along the axis of the support device 20.
[0080] Optionally, combined Figure 1-4 As shown, the mounting pad 21 also includes a transition curved surface 25, which is disposed on the inner peripheral wall of the first through hole 22 and protrudes inward in a curved manner along the radial direction of the first through hole 22. The mounting part 23 corresponds to the transition curved surface 25 along the radial direction of the first through hole 22. When the protrusion 24 is bent and deformed to a preset value under the action of external force, the transition curved surface 25 can abut against the fastener 30. When the protrusion 24 includes a first protrusion 242 and a second protrusion 243, the transition curved surface 25 is located between the first protrusion 242 and the second protrusion 243 along the axial direction of the support device.
[0081] When the protrusion 24 bends and deforms to a preset value under the action of external force, the transition curved surface 25 can abut against the fastener 30. The preset value is within the elastic deformation range of the protrusion 24. After the protrusion 24 bends and deforms to a certain extent under the action of external force, the transition curved surface 25 can abut against the fastener 30, and then the protrusion 24 can automatically return to its original state.
[0082] When the compressor 10 experiences significant shaking during transportation or resonates and vibrates significantly during operation, the protrusion 24 bends and deforms to a preset value under external force, and is unable to support the compressor 10. The transition curved surface 25 then begins to contact the fastener 30 to limit the significant shaking or vibration of the compressor 10.
[0083] like Figure 1 As shown, the inner diameter formed by the apex (highest point) of the transition curved surface 25 is... The inner diameter formed by the valley point (lowest point) of the transition curved surface 25 is: The fastener 30 first contacts the apex of the transition surface 25 and finally contacts the valley point of the transition surface 25. This refers to the radial dimension of the transition curved surface 25.
[0084] When there is a gap between the inner peripheral wall of the first through hole 22 and the fastener 30, when vibration occurs during the operation of the compressor 10, the mounting pad 21 is subjected to radial force and first deforms within the gap. Then, the protrusion 24 contacts and abuts against the fastener 30, and the protrusion 24 bends and deforms, which can reduce vibration. When the protrusion 24 bends and deforms to a preset value under the action of external force, the fastener 30 contacts and abuts against the transition curved surface 25. The protrusion 24 protrudes inward along the radial direction of the first through hole 22, so that the contact between the fastener 30 and the transition curved surface 25 is from point to surface, and the radial stiffness changes evenly. This design can avoid the sudden change in stiffness caused by direct integral contact between the fastener 30 and the inner peripheral wall of the first through hole 22, thereby reducing the vibration impact force of the compressor 10 during operation and transportation and improving the vibration reduction effect.
[0085] Optionally, combined Figure 1 As shown, the first through hole 22 includes a mounting section 221 corresponding to the mounting portion 23. The wall thickness of the mounting section 221 is greater than the thickness of the protrusion 24 along the axial direction of the support device 20. When the protrusion 24 includes a first protrusion 242 and a second protrusion 243, the wall thickness of the mounting section 221 is greater than the total thickness of the first protrusion 242 and the second protrusion 243 along the axial direction of the support device 20.
[0086] The wall thickness of the mounting section 221 is greater than the thickness of the protrusion 24 along the axial direction of the support device 20, which enhances the structural strength of the mounting part 23, reduces deformation of the mounting part 23, and improves stability. When the protrusion 24 includes a first protrusion 242 and a second protrusion 243, the thickness of the protrusion 24 along the axial direction of the support device 20 is the total thickness of the first protrusion 242 and the second protrusion 243 along the axial direction of the support device 20. Furthermore, an appropriate hole wall thickness also helps control the elastic characteristics of the support device 20, enabling it to maintain good support performance while reducing vibration.
[0087] like Figure 1-2 As shown, the outer diameter of the wall of hole 221 in the mounting section is... The inner diameter of the wall of hole 221 in the installation section is: The wall thickness of the hole in the mounting section 221 is The thickness of the protrusion 24 along the axial direction of the support device is J. When the protrusion 24 includes a first protrusion 242 and a second protrusion 243, the thickness J of the protrusion 24 along the axial direction of the support device is J = J1 + J2.
[0088] When the mounting pad 21 includes the transition curved surface 25, the inner diameter dimension of the mounting section 221 hole wall is... The inner diameter dimension formed by the vertex of the transition curved surface 25.
[0089] Optionally, combined Figure 1-2 As shown, the support device 20 also includes a support pad 26, which is connected to the mounting pad 21 and is supported axially between the mounting pad 21 and the preset mounting surface 40. The support pad 26 has a second through hole 27 along the axial direction of the support device. The first through hole 22 and the second through hole 27 are connected axially along the support device. The fastener 30 is adapted to pass through the first through hole 22 and the second through hole 27 in sequence. The second through hole 27 includes an expansion section 271, which is located at one end of the second through hole 27 near the mounting pad 21. The inner diameter of the expansion section 271 is larger than the outer diameter of the fastener 30.
[0090] The compressor 10's support feet 11 are mounted on the mounting pad 21, and the weight of the compressor 10 is applied to the support pad 26 between the mounting pad 21 and the preset mounting surface 40. The mounting pad 21 mainly bears the circumferential and radial vibrations of the compressor 10, while the support pad 26 mainly bears the axial vibrations of the compressor 10. Since the compressor 10 mainly vibrates circumferentially, the protrusion 24 provided on the mounting pad 21 reduces the radial stiffness of the support device 20, thus achieving a vibration reduction effect.
[0091] When the support pad 26 bears the weight of the compressor 10 or is subjected to vertical impact, it will undergo axial deformation. The inner diameter of the expansion section 271 is larger than the outer diameter of the fastener 30, which can provide deformation space for the axial deformation of the support device 20, thereby improving the ability of the entire support device 20 to support the weight of the compressor 10.
[0092] Combination Figure 1-3 As shown, the inner diameter of the expansion section 271 is larger than the outer diameter of the fastener 30, and the inner peripheral wall of the expansion section 271 is recessed along the radial direction of the second through hole 27 toward the outer peripheral wall of the expansion section 271 to form a deformation space.
[0093] Optionally, combined Figure 1-3 As shown, the second through hole 27 includes a mating section 272, which communicates with the first through hole 22. The inner diameter of the mating section 272 is adapted to the outer diameter of the fastener 30.
[0094] The mating section 272 mainly mates with the fastener 30. The inner diameter of the mating section 272 is adapted to the outer diameter of the fastener 30, which can better limit the fastener 30 and make the support device 20 vertical when installed.
[0095] To facilitate the installation of the support device 20 on the screw, the inner diameter of the mating section 272 is as follows: Figure 1 middle As shown, the difference between the inner diameter of the mating section 272 and the outer diameter of the fastener 30 ranges from 0.1 to 2 mm.
[0096] It is understandable that the difference between the inner diameter of the mating section 272 and the outer diameter of the fastener 30 can be 0.1mm, 0.5mm, 1mm, 1.5mm, or 2mm.
[0097] Optionally, combined Figure 1-3 As shown, the second through hole 27 includes a clearance section 273, which is located at one end of the second through hole 27 near the preset mounting surface 40. The support device 20 is connected to the preset mounting surface 40 by fastener 30 and fastening fitting. The inner diameter of the clearance section 273 is adapted to the size of the fastening fitting to provide installation space for the fastening fitting.
[0098] Fastener 30 can be a screw, and the fastening mating part can be a nut. The inner diameter of the clearance section 273 is adapted to the size of the fastening mating part, so that the support pad 26 can make way for the fastening mating part and avoid interference.
[0099] Optionally, combined Figure 3 As shown, the second through hole 27 includes an expansion section 271, a mating section 272, and a clearance section 273. Along the direction of the support device 20 toward the preset mounting surface 40, the expansion section 271, the mating section 272, and the clearance section 273 are connected in sequence.
[0100] The expansion section 271 is located at the end of the second through hole 27 near the mounting pad 21, adjacent to the mounting pad 21. The inner diameter of the expansion section 271 is larger than the outer diameter of the fastener 30, providing axial deformation space for the support pad 26. The mating section 272 is located in the direction of the expansion section 271 toward the preset mounting surface 40. The inner diameter of the mating section 272 matches the outer diameter of the fastener 30, allowing the fastener 30 to pass through and be confined in the support device 20 stably, improving the reliability and stability of the connection between the support device 20 and the fastener 30. The clearance section 273 is located at the end of the mating section 272 near the preset mounting surface 40, providing installation space for the fastening mating part. When the fastener 30 mates with the fastening mating part, interference between the support pad 26 and the fastening mating part can be avoided. The sequential connection of the expansion section 271, the mating section 272, and the clearance section 273 can improve the support effect of the support pad 26.
[0101] Optionally, combined Figure 1-3 As shown, the mounting pad 21 also includes an abutment portion 28, which is connected to the end of the mounting portion 23 away from the support pad 26 and protrudes from the outer peripheral wall of the first through hole 22; wherein, the outer diameter of the mounting portion 23 is smaller than the outer diameter of the abutment portion 28.
[0102] The outer diameter of the mounting part 23 is as follows: Figure 1 middle As shown, the outer diameter of the abutment portion 28 is as follows: Figure 1 middle As shown.
[0103] The abutment portion 28 protrudes from the outer peripheral wall of the first through hole 22 and is connected to the top of the mounting portion 23. When the compressor's support leg 11 is installed in the mounting portion 23, the abutment portion 28 can limit the support leg 11 at the top of the mounting portion 23, thereby improving the connection stability between the support leg 11 and the support device 20. The outer diameter of the mounting portion 23 is smaller than the outer diameter of the abutment portion 28, which can enhance the connection stability between the support device 20 and the compressor 10's support leg 11.
[0104] Optionally, when the second through hole 27 includes an expansion section 271, the outer diameter of the abutment portion 28 is smaller than the outer diameter of the hole wall of the expansion section 271.
[0105] The outer diameter of the expansion section 271 hole wall is as follows: Figure 1 middle As shown.
[0106] When the support pad 26 includes the expansion section 271, the outer diameter of the abutment portion 28 is smaller than the outer diameter of the hole wall of the expansion section 271. This decreasing size design facilitates the installation of the support device 20 on the compressor 10 support leg 11 and prevents the support device 20 from falling off, thereby improving the stability and durability of the overall structure.

The multiple support devices 20 are correspondingly connected to the multiple legs 11. The multiple support devices 20 are arranged sequentially along the circumference of the compressor 10, and the multiple support devices 20 are at the same distance from the center of the compressor. The number of support devices 20 is n, the distance between the support device 20 and the center of the compressor 10 is r, the maximum gas resistance torque of the compressor 10 is Tmax, the elastic modulus of the support device is E, the radial length of the protrusion 24 is X, and the longitudinal cross-sectional area of the protrusion is Sa.
[0110]

[0112] This embodiment defines the radial stiffness of the support device 20.

[0124] Optionally, combined Figure 1As shown, when the protrusion 24 includes a first protrusion 242 and a second protrusion 243, the thickness of the first protrusion 242 along the axial direction of the support device is J1, and the thickness of the second protrusion 243 along the axial direction of the support device is J2.
[0125]
[0126] When the protrusion 24 includes a first protrusion 242 and a second protrusion 243, the thickness of the protrusion 24 along the axial direction of the support device is J = J1 + J2. Since only one of the first protrusion 242 and the second protrusion 243 can be provided, that is, J2 = 0 or J1 = 0.

[0130] The entire support device is made of the same material; therefore, the elastic modulus E and Shore hardness s of all parts of the support device are consistent. The Shore hardness of support device 20 is s, and the relationship between the elastic modulus E and the Shore hardness s of support device 20 is as follows:
[0131]
[0132] Therefore, we can conclude that:
