Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to a compressor resilient base and a compressor including the resilient base. Background Technology

[0002] A compressor typically includes a motor that generates driving force and a pump connected to the motor for compressing the refrigerant, with both the motor and pump housed within the compressor casing. When the compressor operates, the rotational force of the motor drives the pump to compress the refrigerant. This process generates vibration and noise. Typically, the compressor is mounted on feet, which not only secures the compressor but also helps to reduce vibration and noise.

[0003] There are two main types of compressor feet: one type uses a foot with a small hole at the top, which is prone to contact with the positioning screw, causing the compressor vibration to be transmitted to the compressor chassis and generate vibration noise; the other type uses a foot with a large hole, which is less effective at positioning the compressor, especially in current small compressors. Due to their light weight, the compressor may tilt or twist during the welding and pulling process of the pipeline. The large hole foot does not provide proper positioning, resulting in poor system performance.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] To address the problems in the prior art, the present invention aims to provide a compressor elastic foot and a compressor including the same. The compressor elastic foot can reduce the vibration transmitted between the compressor base and the positioning bolt through the elastic foot, reduce the noise caused by the vibration of the compressor base, and simultaneously achieve compressor positioning, reducing the compressor tilt and deflection angle.

[0006] A first aspect of the present invention provides a compressor resilient foot, the resilient foot being cylindrical and having a through hole along its axial direction;

[0007] The inner wall of the through hole is provided with a lower boss and an upper boss, which are configured to support the compressor positioning bolts;

[0008] The outer peripheral surface of the elastic base is provided with a limiting groove, which is configured to engage with the compressor base.

[0009] The upper boss is below the limiting groove, and the inner diameter of the through hole above the upper boss is larger than the inner diameter of the upper boss.

[0010] According to a first aspect of the invention, the vertical distance between the highest point of the upper boss near the positioning bolt and the limiting groove in the axial direction of the elastic base is H, and satisfies: H≥1mm.

[0011] According to a first aspect of the invention, the inner diameter of the upper boss is d, and the inner diameter of the through hole above the upper boss is D, satisfying: 2mm≤Dd≤3mm.

[0012] According to a first aspect of the invention, the cross-section of the upper boss is planar or arc-shaped.

[0013] According to a first aspect of the invention, the upper boss has a thickness of T along the axial direction of the elastic base, and satisfies: T≥2mm.

[0014] According to a first aspect of the invention, the compressor's elastic base is a single piece.

[0015] According to a first aspect of the invention, the compressor's resilient base is made of plastic or rubber.

[0016] According to a first aspect of the present invention, the through hole between the upper boss and the lower boss is a second through hole, and the maximum inner diameter of the through hole above the upper boss is smaller than the maximum inner diameter of the second through hole.

[0017] A second aspect of the present invention provides a compressor, including a base, a positioning bolt, and a compressor elastic foot as described in any one of the above, wherein the base is engaged with a limiting groove of the compressor elastic foot;

[0018] The positioning bolt includes a cap and a screw, with the screw passing through the through hole from bottom to top.

[0019] According to a second aspect of the invention, the distance between the upper boss and the bolt is L, and satisfies: 0.5mm≤L≤1.5mm, and / or the distance between the lower boss and the bolt is l, and satisfies: 0≤l≤0.25mm.

[0020] The compressor of this invention has a lower boss and an upper boss inside the through hole of the elastic foot, and a limiting groove is provided on the outer peripheral surface to achieve positioning with the compressor base and the positioning bolt, thereby reducing the tilt and deflection angle of the compressor. At the same time, since the upper boss and the limiting groove are not set on the same plane, the vibration transmitted between the compressor base and the positioning bolt through the elastic foot is reduced. When the compressor tilts or deflects, the upper boss achieves elastic contact between the elastic foot and the positioning bolt, thereby reducing the noise caused by the vibration transmission of the compressor base and achieving vibration reduction and noise reduction.

[0031] This invention provides a compressor resilient base and a compressor including the resilient base. The resilient base is cylindrical and has a through hole along its axial direction. The inner wall of the through hole has a lower boss and an upper boss, which are configured to support a compressor positioning bolt. The outer circumferential surface of the resilient base has a limiting groove, which is configured to engage with a compressor base. The upper boss is located below the limiting groove. Preferably, the vertical distance H between the highest point of the upper boss near the positioning bolt and the limiting groove along the axial direction of the resilient base satisfies: H ≥ 1 mm. Further, H is less than half the height of the through hole to avoid affecting positioning and causing compressor torsion. The compressor of this invention has a lower boss and an upper boss inside the through hole of the elastic foot, and a limiting groove is provided on the outer peripheral surface to achieve positioning with the compressor base and the positioning bolt, thereby reducing the tilt and deflection angle of the compressor. At the same time, since the upper boss and the limiting groove are not set on the same plane, the vibration transmitted between the compressor base and the positioning bolt through the elastic foot is reduced. When the compressor tilts or deflects, the upper boss achieves elastic contact between the elastic foot and the positioning bolt, thereby reducing the noise caused by the vibration transmission of the compressor base and achieving vibration reduction and noise reduction.

[0032] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the compressor elastic base and the compressor including therein. It should be understood that the various specific embodiments are not intended to limit the scope of protection of the present invention.

[0033] Figure 1 and Figure 2 The images show a schematic diagram and a cross-sectional view of the compressor elastic foot according to the first embodiment of the present invention. Specifically, the compressor elastic foot 1 is cylindrical and has a through hole 11 along its axial direction. The inner wall of the through hole 11 has a lower boss 111 and an upper boss 112. When the compressor elastic foot 1 is used in a compressor, the lower boss 111 and the upper boss 111 are configured to support the compressor positioning bolts. The outer circumferential surface of the elastic foot 1 has a limiting groove 13. When the compressor elastic foot 1 is used in a compressor, the limiting groove 13 is configured to engage with the compressor base. The upper boss 112 is below the limiting groove 13. The vertical distance between the upper boss 11 and the limiting groove 13 in the axial direction of the elastic foot 1 is H, and satisfies: H≥1mm. In the first embodiment, the compressor elastic foot 1 is a single piece, which can be a plastic part or a rubber part. The plastic part can be a high-damping plastic part. A single rubber part helps to maintain the elasticity of the elastic foot and its service life.

[0034] When the elastic foot 1 is engaged with the positioning bolt of the compressor, the upper boss 112 is the contact point between the elastic foot 1 and the screw of the positioning bolt, and the limiting groove 13 is the contact point between the elastic foot 1 and the compressor base. When the two are on the same plane, the probability of vibration of the compressor base being transmitted to the positioning bolt through the limiting groove 13 and the upper boss 112 increases, thereby causing noise. In this invention, the upper boss and the limiting groove are not on the same plane, or rather, the upper boss is below the limiting groove. The vertical distance H between the two can be determined according to the structure of the compressor and the compressor base, thereby minimizing the vibration transmitted between the compressor base and the positioning bolt through the elastic foot, reducing the noise caused by the vibration transmission of the compressor base, and achieving vibration reduction and noise reduction.

[0035] The structural features of the compressor's flexible base will be further explained below in conjunction with its application in the compressor. Figure 3 and Figure 4 This is a cross-sectional view of the elastic foot of the first embodiment of the present invention when used in a compressor. The compressor also includes a compressor base 3 and a positioning bolt. The compressor base 3 engages with the limiting groove 13 of the compressor elastic foot 1. In practice, the portion of the compressor elastic foot 1 above the limiting groove 13 passes through a through hole on the compressor base 3, and the inner wall of the through hole on the compressor base 3 engages with the limiting groove 13. The positioning bolt includes a cap 21 and a screw 22. The screw 22 passes through the through hole 11 from bottom to top. In the first embodiment, the cross-section of the upper boss 112 is planar, that is, the inner circumference of the upper boss 112 is planar. In this case, the inner circumferential plane of the upper boss 112 is parallel to the screw 22 of the positioning bolt. The distance between the plane of the upper boss 112 and the outer circumferential surface of the bolt 22 is defined as L, and satisfies: 0.5mm ≤ L ≤ 1.5mm, such as L being 1.0mm, etc. Test results show that when L is within the above range, the effects of compressor tilting and torsion are reduced. Furthermore, the thickness of the upper boss 112 along the axial direction of the elastic foot 1 is T. In this embodiment, T is the thickness of the plane in the axial direction, which satisfies: T≥2mm.

[0036] Similarly, to reduce the vibration transmitted between the compressor base and the positioning bolt through the elastic foot, the inner diameter of the upper part of the through hole 11 of the elastic foot 1, i.e., the part above the upper boss 112, is D, and the inner diameter of the upper boss 112 is d, with 2mm ≤ Dd ≤ 3mm. In this case, the elastic foot 1 does not have a position that directly abuts against both the screw and the compressor base along the axial direction, thus reducing the direct transmission of vibration. Furthermore, as... Figure 2As shown, the through hole between the upper boss 112 and the lower boss 111 is the second through hole, and the maximum inner diameter of the through hole above the upper boss is smaller than the maximum inner diameter of the second through hole. This structure further reduces the vibration transmitted from the compressor to the chassis through the elastic feet. At the same time, the feet have better elasticity.

[0037] In the first embodiment, there is a certain gap between the lower boss 111 and the bolt 22, and the distance or gap between the two is l. Optionally, l < L. Preferably, l satisfies: 0 ≤ l ≤ 0.25 mm. In addition, in order to eliminate a certain inclination of the compressor base, the outer peripheral surface of the elastic foot 1 is wavy or serrated along its axial direction, as Figure 2 shown. This wavy or serrated structure increases the elasticity of the elastic foot in the axial direction and reduces the vibration transmitted from the compressor to the chassis through the elastic foot.

[0038] Figure 5 This is a sectional view of the elastic foot of the compressor according to the second embodiment of the present invention. Among them, the cross-section of the upper boss 112b of the elastic foot 1b of the compressor is arc-shaped. At this time, the distance between the top of the arc-shaped upper boss 112b and the outer peripheral surface of the bolt 22 is defined as L, and the distance L also needs to be between 0.5 mm and 1.5 mm.

[0039] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application. Any reference signs in the claims should not be regarded as limiting the claimed rights.
