Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a vibration damping structure and a compressor adopting the vibration damping structure. Background Art

[0002] Due to its structural limitations, the rotary compressor of a household air conditioner cannot achieve torque balance within the full speed range, resulting in relatively large vibrations. Reducing the vibrations of the rotary compressor can effectively reduce the vibrations of the air conditioning system. In the prior art, vibration damping pads are mainly used to achieve the vibration damping of the compressor. The fasteners (such as bolts) for fixedly installing the compressor to the installation surface pass through the inner holes of the vibration damping pads. Through the damping effect of the vibration damping pads, the axial vibrations of the compressor can be effectively reduced. The existing vibration damping pads all adopt the assembly method along the axial direction of the compressor, and the effect of reducing vibrations is limited. Summary of the Utility Model

[0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is to provide a vibration damping structure that can effectively reduce the radial and axial vibrations of a vibrating body.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

Each group of vibration damping components includes a base and a damper. The base is connected to the outer surface of the vibrating body. One end of the damper is connected to the base, and the other end is used to connect to the installation surface. A through hole for the fastener to pass through is formed axially through the damper, and the axial direction of the damper forms an angle with the axial direction of the vibrating body.

[0006] Preferably, the axes of the dampers of all the vibration damping components intersect at the same intersection point.

[0007] Preferably, the intersection point is located on the first centroid axis, and the first centroid axis is parallel to the axis of the vibrating body and passes through the centroid of the vibrating body.

[0009] Preferably, the intersection point is located on the second centroid axis, and the second centroid axis is parallel to the axis of the vibrating body and passes through the centroid of the overall structure composed of the vibrating body and all the vibration damping components.

[0010] Preferably, the intersection point coincides with the centroid of the overall structure.

[0011] Preferably, the base has a mounting plate for connecting the damper. The mounting plate forms an angle with the axial direction of the vibrating body and is perpendicular to the axial direction of the damper.

[0012] Preferably, an installation hole penetrating axially along the damper is formed in the installation plate, and an annular clamping groove is formed circumferentially on the outer peripheral surface of the damper.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0035] In addition, in the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0036] As Figure 1 and Figure 2 shown, it is an embodiment of the vibration damping structure provided by the present utility model. The vibration damping structure of this embodiment is used to mount the vibrating body 1 (such as a compressor) onto the mounting surface 2 (such as the inner side surface of the equipment housing), and the vibration damping structure is disposed between the vibrating body 1 and the mounting surface 2, and damping is provided by the vibration damping structure to achieve the vibration damping effect.

[0037] The vibration damping structure of this embodiment includes multiple groups of vibration damping components 3. All the vibration damping components 3 are arranged at intervals along the circumferential direction of the vibrating body 1 on the outer surface of the vibrating body 1. Each vibration damping component 3 is respectively connected to the mounting surface 2. Thus, the vibrating body 1 is installed on the mounting surface 2 by multiple groups of vibration damping components 3 together, and a plurality of support points for supporting the vibrating body 1 are formed along the circumferential direction of the vibrating body 1, so as to ensure the stability of the vibrating body 1 after being installed on the mounting surface 2. Preferably, all the vibration damping components 3 are evenly distributed along the circumferential direction of the vibrating body 1 to ensure stable support for the vibrating body 1. The number of the vibration damping components 3 is not limited, and the corresponding number of vibration damping components 3 can be set according to the vibration condition of the vibrating body 1, so that the overall vibration damping capacity of the vibration damping structure matches the vibration damping requirement. Preferably, there are at least three groups of vibration damping components 3 to form a more stable support in the circumferential direction of the vibrating body 1.

[0038] Each group of vibration damping components 3 includes a base 31 and a damper 32. Among them, the base 31 is connected to the outer surface of the vibrating body 1. The base 31 is preferably rigid, and the vibration damping component 3 is installed and fixed on the outer surface of the vibrating body 1 through the base 31. One end of the damper 32 is connected to the base 31, and the other end of the damper 32 is used to connect to the mounting surface 2. The damper 32 provides damping to absorb the vibration of the vibrating body 1 and plays a role in vibration damping. The damper 32 is preferably made of an elastic material, and the elastic material for making the damper 32 is preferably rubber. A through hole is formed axially through the inside of the damper 32, and the through hole is for a fastener to pass through. The fastener is used to connect and fix the base 31 and the mounting surface 2, so as to install and fix the vibrating body 1 on the mounting surface 2. The fastener is preferably a bolt. The axis of the damper 32 forms an angle with the axis of the vibrating body 1, so that the radial and axial vibrations of the vibrating body 1 can be transmitted to the damper 32, and the vibration is absorbed by the damping and deformation of the damper 32, thereby effectively reducing the radial and axial vibrations of the vibrating body 1 and achieving a better vibration damping effect.

[0039] In this embodiment, preferably, the axes of the dampers 32 of all the vibration damping components 3 intersect at the same intersection point A, and the intersection point A is located inside the vibrating body 1, so that each vibration damping component 3 effectively cooperates in the circumferential direction of the vibrating body 1, and thus the overall vibration damping effect of the vibration damping structure is better.

[0040] Furthermore, in a preferred embodiment, the intersection point A of the axes of the dampers 32 of all the vibration damping components 3 is located on the first centroid axis L1. The first centroid axis L1 is parallel to the axis of the vibrating body 1 and passes through the centroid of the vibrating body 1. Thus, the overall vibration damping structure can play a better role in damping the vibration of the vibrating body 1, and at the same time take into account the good support and limiting function for the vibrating body 1 to ensure the stability of the vibrating body 1. Among them, when the intersection point A is located at a position on the first centroid axis L1 close to the centroid of the vibrating body 1, the overall vibration damping effect of the vibration damping structure is better, and the support and limiting effect is also better. Optimally, the intersection point A coincides with the centroid of the vibrating body 1.

[0041] In another preferred embodiment, the intersection point A of the axes of all the dampers 32 of the damping assembly 3 is located on the second centroid axis L2, and the second centroid axis L2 is parallel to the axis of the vibrating body 1 and passes through the centroid of the overall structure formed by the vibrating body 1 and all the damping assemblies 3. Thus, the overall damping structure can also better damp the vibration of the vibrating body 1, while taking into account the good support and limiting function for the vibrating body 1 to ensure the stability of the vibrating body 1. Among them, when the intersection point A is located at a position on the second centroid axis L2 close to the centroid of the overall structure formed by the vibrating body 1 and all the damping assemblies 3, the overall damping effect of the damping structure is better, and the support and limiting effect is also better. Optimally, the intersection point A coincides with the centroid of the overall structure formed by the vibrating body 1 and all the damping assemblies 3.

[0042] In practical applications, the above-mentioned first centroid axis L1 and the second centroid axis L2 may coincide or may not coincide.

[0043] In this embodiment, preferably, the base 31 has a mounting plate 311 for connecting the damper 32, and the mounting plate 311 forms an angle with the axis of the vibrating body 1 and is perpendicular to the axis of the damper 32. The angle formed by the mounting plate 311 and the axis of the vibrating body 1 is α, and the angle formed by the axis of the damper 32 and the axis of the vibrating body 1 is β, and α and β are complementary angles.

[0044] Preferably, the base 31 further has a connecting plate 312, and the connecting plate 312 is provided at one end of the outer surface of the mounting plate 311 close to the vibrating body 1. The connecting plate 312 is in contact with and fixedly connected to the outer surface of the vibrating body 1. The connecting plate 312 forms an angle with the mounting plate 311, so that the angle of the mounting plate 311 relative to the axis of the vibrating body 1 meets the requirements.

[0045] In this embodiment, preferably, the mounting plate 311 is provided with a mounting hole 313 penetrating along the axis of the damper 32, and a circumferential annular groove 321 is provided on the outer circumferential surface of the damper 32. The damper 32 is clamped with the mounting hole 313 through the annular groove 321, so that the damper 32 is passed through the mounting plate 311 of the base 31.

[0046] For the connection manner of the damper 32 and the mounting surface 2, in a preferred embodiment, such as Figure 1As shown in the figure, the installation surface 2 is provided with an inclined assembly surface 21, and the inclined assembly surface 21 is parallel to the mounting plate 311 of the base 31, so as to facilitate the placement of the damper 32. The damper 32 is used to connect the end face of one end of the installation surface 2 to the inclined assembly surface 21 provided on the installation surface 2. The end face of the damper 32 for connecting one end of the installation surface 2 is placed in a fitting manner on the inclined assembly surface 21. The fastener passes through the through hole axially penetrating inside the damper 32 and then is connected and fixed to the inclined assembly surface 21, realizing the connection and fixation between the base 31 and the inclined assembly surface 21, thereby mounting and fixing the vibrating body 1 to the inclined assembly surface 21 of the installation surface 2.

[0047] In another preferred embodiment, as Figure 2 shown, one end of the damper 32 for connecting the installation surface 2 is provided with a connection block 33. The connection block 33 is rigid. One end of the connection block 33 away from the damper 32 has a connection surface 331, and the connection surface 331 is adapted to the installation surface 2. The end face of the damper 32 for connecting one end of the installation surface 2 is attached to the connection block 33. The fastener passes through the through hole axially penetrating inside the damper 32 and then is connected and fixed to the connection block 33, realizing the connection and fixation between the base 31 and the connection block 33; the connection surface 331 of the connection block 33 is placed in a fitting manner on the installation surface 2 and is connected and fixed by a connecting member (such as a screw or a bolt), thereby realizing the connection and fixation between the base 31 and the installation surface 2, and thus mounting and fixing the vibrating body 1 to the installation surface 2. By adding the connection block 33 to adapt to the angle between the damper 32 and the installation surface 2, it is convenient to connect the damper 32 to the installation surface 2 which is integrally planar, without the need to provide an inclined assembly surface 21 on the installation surface 2, and the assembly adaptability is better.

[0048] Based on the vibration damping structure of the present invention, the embodiments of the present invention further provide a compressor. The compressor of this embodiment adopts the above-mentioned vibration damping structure of this embodiment. Taking the compressor as the vibrating body 1 and the inner side surface of the temperature control device housing as the installation surface 2, the above-mentioned vibration damping structure of this embodiment is provided on the housing (main housing or lower housing) of the compressor, and the compressor is installed on the inner side surface of the temperature control device housing through this vibration damping structure. By the damper 32 arranged at an angle to the axial direction of the compressor, the radial and axial vibrations of the compressor can be effectively reduced, and a better vibration damping effect can be achieved.

[0049] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
