Description

Technical Field

[0001] This utility model belongs to the technical field of shock absorption devices, and specifically relates to a low-noise compressor assembly. Background Technology

[0002] Currently, energy storage devices typically use liquid-cooled air conditioners to cool the batteries and electronic control equipment, ensuring normal operation. To facilitate installation and reduce costs, liquid-cooled air conditioners are usually designed as integrated units, housing the compressor, fan, condenser, and other components in the same enclosure. However, because the condenser needs to exchange heat with the outside air, the interior of the liquid-cooled air conditioner is connected to the external environment, and the unit's operating noise is transmitted to the surrounding environment through the air outlet.

[0003] Existing compressors are generally fixed directly to the liquid-cooled air conditioning unit using fixed brackets. However, existing mounting brackets either use a simple primary vibration damping structure, resulting in high noise, or a secondary vibration damping structure that can only dampen vibrations in the vertical direction, which is complex, costly, and has limited applicability. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a low-noise compressor assembly to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A low-noise compressor assembly includes a compressor body and a support frame. The compressor body is detachably mounted on the support frame. The assembly also includes a primary damping component and a secondary damping component. The vibration transmission direction of the primary damping component forms an acute angle α with the mounting plane of the compressor body, and the vibration transmission direction of the secondary damping component forms a right angle with the mounting plane of the compressor body.

[0007] As a preferred technical solution, α is 30° to 45°.

[0008] As a preferred technical solution, the support frame includes an upper shock-absorbing bracket and a lower shock-absorbing bracket.

The upper shock-absorbing bracket includes a mounting foot for connecting the primary shock-absorbing component and a mounting plate for mounting the compressor body. The mounting foot is integrally connected to the outside of the mounting plate.

[0010] As a preferred technical solution, the primary damping component includes an upper damping pad, with the top of the first mounting foot vertically mounted on the upper damping pad. The first mounting foot forms an angle α with the plane of the mounting plate, and the first mounting foot gradually moves upward towards the compressor body.

[0011] As a preferred technical solution, at least two sets of mounting holes are provided on the mounting foot one, and the top of the upper shock-absorbing pad is installed on the mounting foot one by bolts and mounting holes one.

[0012] As a preferred technical solution, the mounting hole of one of the mounting feet is a U-shaped hole, and the U-shaped hole has a notch facing outward.

[0013] As a preferred technical solution, the lower shock absorber bracket is made by cutting and bending a whole piece of sheet metal into a cantilever state, and the lower shock absorber bracket is about the central axis.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example 1

[0024] refer to Figures 1 to 4 The low-noise compressor assembly described in this embodiment includes a compressor body 1, two sets of upper shock-absorbing brackets 2 and lower shock-absorbing brackets 3. The compressor body 1 is mounted on the upper shock-absorbing brackets 2 by multiple sets of fixing bolts 6. An upper shock-absorbing pad 4 is installed between the upper shock-absorbing brackets 2 and the lower shock-absorbing brackets 3. The upper shock-absorbing pad 4 forms an acute angle with the mounting plane of the compressor body 1 and gradually moves downward as it approaches the compressor body 1. A lower shock-absorbing pad 6 is installed at the bottom of the lower shock-absorbing bracket 3 and is perpendicular to the compressor mounting plane.

[0025] Preferably, the upper shock-absorbing pad 4 is at an angle α relative to the compressor mounting plane, where α is 30° to 45°.

[0026] The upper damping pad 4 forms an acute angle with the mounting plane of the compressor body 1, which differs from the direction of vibration transmission in vertical installations. This significantly reduces the vibration generated by the compressor body 1 during operation, and, together with the flexible upper damping pad 4, greatly reduces noise. The upper damping pad 4 is a primary damping device, while the lower damping pad 6 is a secondary damping device. The secondary damping device enhances the damping effect, thereby effectively improving the noise situation.

[0027] Preferably, the upper shock absorber bracket 2 includes a mounting foot 21 for connecting the upper shock absorber pad 4 and a mounting plate 22 for mounting the compressor body 1. The mounting foot 21 is integrally connected to the outside of the mounting plate 22. The mounting foot 21 is installed perpendicular to the upper shock absorber pad 4. Therefore, the plane where the mounting foot 21 and the mounting plate 22 are located is at an angle α, and the mounting foot 21 gradually moves upward towards the compressor body 1.

[0028] Preferably, the two sets of upper shock-absorbing brackets 2 are symmetrical about the compressor body 1 axis, which reduces material weight and is beneficial to the overall lightweight structure.

[0029] Specifically, at least two sets of mounting holes 24 are provided on the mounting foot 21, and the top of the upper shock-absorbing pad 4 is installed on the mounting foot 21 by bolts and mounting holes 24; at least two sets of assembly holes 23 are provided on the mounting plate 22, and the fixing bolts 6 are inserted into the assembly holes 23 and fixed.

[0030] Preferably, the mounting holes 24 of one set of mounting feet 21 are U-shaped holes 25, with the U-shaped holes 25 having a notch facing outwards. This makes it easy to align the bolts when installing the shock-absorbing pad 4, and facilitates assembly.

[0031] Preferably, the lower shock absorber bracket 3 is made by bending a whole piece of sheet material at an angle so that the whole is in a cantilever state, which increases flexibility without reducing strength, effectively reducing shock and thus reducing noise.

[0032] Specifically, the lower shock absorber bracket 3 includes a base plate 32, two sets of mounting feet 31 and two sets of mounting plates 35. The mounting feet 31 and mounting plates 35 are smoothly connected. The two ends of the base plate 32 are smoothly connected to the two sets of mounting feet 31 through a set of connecting plates 36. The two sets of mounting feet 31 and the two sets of mounting plates 35 are symmetrical about the base plate 32. The mounting feet 31 are parallel to the mounting feet 21, that is, the mounting feet 31 and the mounting plane of the compressor body 1 are at an angle α. The base plate 32 and the connecting plates 36 are at an obtuse angle β. The height of the base plate 36 is between the height difference of the mounting feet 31 and the mounting plates 35 are lower than the mounting feet 31.

[0033] Preferably, β is 120° to 150°, and the obtuse angle of 120° to 150° between the base plate 32 and the connecting plate 36 can increase the strength of the lower shock-absorbing bracket 3 and avoid the compressor body 1 during vibration, making the structure compact.

[0034] Specifically, mounting feet 2 and 31 are provided with mounting holes 2 and 33 respectively. The bottom end of the upper shock absorber 4 is mounted on mounting feet 2 and 31 by bolts and mounting holes 2 and 33. The upper shock absorber 4 is perpendicular to mounting feet 2 and 31. Mounting plate 3 and 35 are provided with at least two sets of mounting holes 3 and 34 respectively. The top end of the lower shock absorber 6 is fixedly mounted on mounting plate 3 and 35 by bolts and mounting holes 3 and 34.

[0035] This device is installed and fixed on the liquid-cooled air conditioner. When the compressor is running, it provides secondary vibration damping through the upper damping pad 4 and the lower damping pad 5, and changes the traditional single vertical vibration direction. This can effectively reduce the vibration and noise transmitted to the liquid-cooled air conditioner, which is beneficial to extending the service life of the compressor body 1 and reducing the operating noise of the liquid-cooled air conditioner.
