Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to a housing assembly and a compressor having the same. Background Technology

[0002] As refrigeration compressors are used in more and more applications, they are also used in some small, enclosed spaces. However, the requirements for noise and vibration of compressors in small, enclosed spaces are very stringent.

[0003] Existing methods for reducing noise and vibration in refrigeration compressors can be approached from two aspects: firstly, reducing the source of noise and vibration; and secondly, hindering the propagation of noise and vibration. The housing assembly can play a role in hindering the propagation of noise and vibration, but the housings of existing small compressors have poor sound insulation. Therefore, how to improve the sound insulation effect of the housing through optimized design is a problem that urgently needs to be solved in current technology. Utility Model Content

[0004] This invention provides a housing assembly and a compressor having the same, to solve the existing problem of how to improve sound insulation by optimizing the housing.

[0005] According to one aspect of the present invention, a housing assembly is provided, comprising an upper shell and a lower shell, both surfaces of which are curved. The upper and lower shells are interlocked to form a sealed chamber. The ratio of the length dimension to the width dimension of the housing assembly is between 1.2 and 1.25, the ratio of the width dimension to the height dimension of the housing assembly is between 0.88 and 0.98, and the ratio of the height dimension to the length dimension of the housing assembly is between 0.84 and 0.85.

[0006] Furthermore, the end of the upper shell closest to the lower shell is located inside the lower shell, and the overlap between the upper shell and the lower shell in the height direction is between 7 mm and 7.5 mm.

[0007] Furthermore, the ratio of the length dimension to the width dimension of the upper shell is between 1.2 and 1.25, the ratio of the width dimension to the height dimension of the upper shell is between 2.1 and 2.2, and the ratio of the height dimension to the length dimension of the upper shell is between 0.38 and 0.4.

[0008] Furthermore, the ratio of the length dimension to the width dimension of the lower shell is between 1.2 and 1.25, the ratio of the width dimension to the height dimension of the lower shell is between 1.2 and 1.25, and the ratio of the height dimension to the length dimension of the lower shell is between 0.68 and 0.7.

[0009] Furthermore, the inner surface of the upper shell has multiple limiting protrusions, which are symmetrically distributed on both sides of the upper shell along its length.

[0010] Furthermore, the plurality of limiting protrusions include a first protrusion, a second protrusion, a third protrusion, and a fourth protrusion. The first and second protrusions are symmetrically distributed on both sides of the upper shell along the length direction of the upper shell, and the third and fourth protrusions are symmetrically distributed on both sides of the upper shell along the length direction of the upper shell. The side of the first, second, third, and fourth protrusions facing the center of the upper shell has a limiting chamfer. The ratio of the limiting chamfer of the first and second protrusions is equal to the ratio of the limiting chamfer of the third and fourth protrusions.

[0011] Furthermore, the inner surface of the lower shell has multiple supporting protrusions, which are symmetrically distributed on both sides of the lower shell along its length.

[0012] Furthermore, the multiple support protrusions include a fifth protrusion, a sixth protrusion, a seventh protrusion, and an eighth protrusion. The fifth and sixth protrusions are symmetrically distributed on both sides of the lower shell along the length direction of the lower shell, and the seventh and eighth protrusions are symmetrically distributed on both sides of the lower shell along the length direction of the lower shell. The height of the fifth protrusion is the same as the height of the sixth protrusion, and the height of the seventh protrusion is the same as the height of the eighth protrusion.

[0013] Furthermore, the height of the fifth protrusion is lower than the height of the seventh protrusion, and the height difference between the fifth and seventh protrusions is between 1 mm and 1.2 mm.

[0014] According to another aspect of the present invention, a compressor is provided, including the aforementioned housing assembly.

[0015] The technical solution of this utility model employs a curved upper and lower shell structure, with the two parts interlocking to form a complete sealed chamber. By maintaining the length-to-width ratio of the shell assembly between 1.2 and 1.25, the width-to-height ratio between 0.88 and 0.98, and the height-to-length ratio between 0.84 and 0.85, the shell's shape is close to that of a sphere. This configuration evenly distributes stress and significantly enhances the overall rigidity of the shell assembly. The increased rigidity raises the natural frequency of the shell assembly, ensuring it is significantly higher than common external excitation frequencies, such as mechanical vibration and sound wave frequencies, thereby effectively reducing or avoiding shell resonance. This design effectively suppresses noise and vibration caused by resonance during compressor operation, further improving the overall sound insulation of the shell. Attached Figure Description

[0039] 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.

[0040] like Figure 1 and Figure 2 As shown, this embodiment of the present invention provides a housing assembly, which includes an upper shell 10 and a lower shell 20. Both the surfaces of the upper shell 10 and the lower shell 20 are curved surfaces, and the upper shell 10 and the lower shell 20 are interlocked to form a sealed chamber. Specifically, the circumferential surfaces of the upper shell 10 and the lower shell 20 in terms of length and width are curved surfaces, as are the circumferential surfaces in terms of height and length, and the circumferential surfaces in terms of height and width. The ratio of the length dimension to the width dimension of the housing assembly is between 1.2 and 1.25, specifically 1.2, 1.23, and 1.25. The ratio of the width dimension to the height dimension of the housing assembly is between 0.88 and 0.98, specifically 0.88, 0.9, 0.92, and 0.98. The ratio of the height dimension to the length dimension of the housing assembly is between 0.84 and 0.85, specifically 0.84 and 0.85. For example... Figure 3 and Figure 4 As shown, in this embodiment, H is the height of the housing assembly, L is the length of the housing assembly, and W is the width of the housing assembly.

[0041] The technical solution of this utility model employs a curved structure for both the upper shell 10 and the lower shell 20, which are interlocked to form a complete sealed chamber. By maintaining the length-to-width ratio of the shell assembly between 1.2 and 1.25, the width-to-height ratio between 0.88 and 0.98, and the height-to-length ratio between 0.84 and 0.85, the shell's shape is close to that of a sphere. This configuration evenly distributes stress and significantly enhances the overall rigidity of the shell assembly. The increased rigidity raises the natural frequency of the shell assembly, ensuring it is much higher than common external excitation frequencies, such as mechanical vibration and sound wave frequencies, thereby effectively reducing or avoiding shell resonance. This design effectively suppresses noise and vibration caused by resonance during compressor operation, further improving the overall sound insulation of the shell.

[0042] The end faces of the upper shell 10 and the lower shell 20 can be fitted together or offset. In this embodiment, the end of the upper shell 10 closest to the lower shell 20 is located inside the lower shell 20, and the overlap in height between the upper shell 10 and the lower shell 20 is between 7mm and 7.5mm. Specifically, it can be 7mm, 7.2mm, 7.4mm, or 7.5mm. Figure 4 As shown in the figure, in this embodiment, the dimension in which the upper shell 10 and the lower shell 20 overlap in the height direction is represented by h.

[0043] If the embedding depth is less than 7mm during assembly of the housing assembly, the connection between the upper housing 10 and the lower housing 20 will be unstable, leading to shaking during compressor operation and increasing noise and vibration. If the embedding depth exceeds 7.5mm, it will unnecessarily increase the overall weight and volume of the housing assembly, and excessive embedding will also increase assembly difficulty and operational challenges. Therefore, in this embodiment, the overlap dimension of the upper housing 10 and the lower housing 20 in the height direction is set between 7mm and 7.5mm. By determining the above range, a tight and stable connection is formed between the upper housing 10 and the lower housing 20, which not only strengthens the overall rigidity of the housing and effectively improves its vibration resistance and reduces operating noise, but also takes into account the assembly accuracy and mechanical performance of the housing assembly, achieving the goal of compressor miniaturization and weight reduction without sacrificing its reliability and durability.

[0044] In this embodiment, the ratio of the length to the width of the upper shell 10 is between 1.2 and 1.25, specifically 1.2, 1.22, and 1.25. The ratio of the width to the height of the upper shell 10 is between 2.1 and 2.2, specifically 2.1, 2.15, and 2.2. The ratio of the height to the length of the upper shell 10 is between 0.38 and 0.4, specifically 0.38, 0.39, and 0.4. Figure 5 and Figure 6 As shown, the length of the upper shell 10 is represented by L1, the width of the upper shell 10 is represented by W1, and the height of the upper shell is represented by H1.

[0045] Studies have found that when the ratio of the length to the width of the upper housing 10 is less than 1.2, meaning the difference between the length and width of the upper housing 10 is too small, the stability and deformation resistance of the housing will be affected when subjected to longitudinal or lateral external loads. This may lead to more frequent resonance and increase compressor operating noise. Furthermore, an excessively close length-to-width ratio can restrict the rational layout of internal space, affecting the installation and heat dissipation efficiency of compressor components. If the ratio is higher than 1.25, the upper housing 10 extends excessively in the length direction, disrupting the overall structural balance and increasing the weight and volume of the housing components. In addition, an excessively large length-to-width ratio may cause uneven stress at the connection points, affecting connection strength and long-term reliability. Simultaneously, the asymmetry of the housing structure will exacerbate vibration and noise problems, hindering the efficient and stable operation of the compressor. In this application, by setting the ratio of the length to the width of the upper shell 10 between 1.2 and 1.25, the structural instability caused by the disproportionate size of the shell is avoided, while ensuring sufficient internal space to accommodate the core components of the compressor and maintain its normal and efficient operation.

[0046] In this embodiment, the ratio of the width to the height of the upper shell 10 is set between 2.1 and 2.2. Specifically, a ratio below 2.1 indicates that the upper shell 10 is designed to be too flat and wide, weakening the strength of its longitudinal structure. This reduces the structural rigidity of the shell assembly, decreasing its resistance to external mechanical impacts and sound waves, making the compressor more prone to resonance and noise during operation. A ratio above 2.2 indicates that the upper shell 10 is too tall or too long and narrow, with a height that is too large relative to its width. This causes the center of gravity of the shell assembly to shift upward, affecting the stability of the compressor operation and increasing vibration and noise. In this embodiment, by setting the above ratio, the weakening of the shell assembly's rigidity due to an imbalance in the width-to-height ratio of the upper shell 10 is effectively avoided, thus improving the rigidity of the shell assembly.

[0047] In this embodiment, the ratio of the height to the length of the upper housing 10 is between 0.38 and 0.4. Specifically, when the ratio is less than 0.38, the height-to-length ratio of the upper housing 10 is too small, resulting in insufficient rigidity in the height direction. This makes the upper housing 10 susceptible to bending deformation due to longitudinal external forces, which in turn affects the stable operation of the compressor and increases noise. When the ratio is greater than 0.4, the height-to-length ratio of the upper housing 10 is too large, increasing the weight and volume of the housing in the longitudinal direction. In this embodiment, the design of the above ratio ensures the structural balance of the upper housing 10 in both the vertical and longitudinal directions, thereby effectively suppressing vibration during compressor operation and reducing noise levels. At the same time, this design also ensures installation space for the internal components of the upper housing 10 and makes the compressor more compact and lightweight.

[0048] Further, in this embodiment, the ratio of the length to the width of the lower shell 20 is between 1.2 and 1.25, specifically 1.2, 1.23, and 1.25. The ratio of the width to the height of the lower shell 20 is between 1.2 and 1.25, specifically 1.2, 1.23, and 1.25. The ratio of the height to the length of the lower shell 20 is between 0.68 and 0.7, specifically 0.68, 0.69, and 0.7. Figure 7 and Figure 8 As shown, in this embodiment, the length of the lower shell is represented by L2, the width by W2, and the height by H2.

[0049] In this embodiment, the ratio of the length to the width of the lower shell 20 is between 1.2 and 1.25. Specifically, if the ratio is less than 1.2, meaning the length-to-width ratio of the lower shell 20 is too small, the rigidity of the lower shell 20 in the width direction is relatively excessive, while the rigidity in the length direction is relatively low. Such structural imbalance can easily lead to twisting or deformation during compressor operation, especially when subjected to external forces in the length direction, resulting in decreased shell stability and causing unnecessary vibration and noise. Conversely, when the ratio is higher than 1.25, it means the length-to-width ratio of the lower shell 20 is increased, and the structural asymmetry leads to excessive rigidity in the length direction and insufficient rigidity in the width direction. This asymmetrical rigidity distribution not only increases the amount of material used but also increases the volume and weight of the lower shell 20. Therefore, in this embodiment, by setting the length and width of the lower shell 20 within the above-mentioned ratio range, the rigidity of the lower shell 20 is effectively improved, further increasing the natural frequency of the shell assembly and enhancing the sound insulation effect of the shell assembly.

[0050] Furthermore, the ratio of the width to the height of the lower housing 20 is set between 1.2 and 1.25. Specifically, when the ratio is less than 1.2, it means that the width of the lower housing 20 is too narrow relative to its height. This leads to a decrease in the rigidity of the housing in the lateral direction, making the lower housing 20 prone to deformation under lateral external forces, especially under high-frequency vibration or high-pressure conditions. The stability of the housing will decrease significantly, increasing the noise and energy consumption of the compressor during operation. Conversely, when the ratio is higher than 1.25, the width of the lower housing 20 becomes too large relative to its height. This results in excessive rigidity of the housing assembly in the vertical direction, while the lateral rigidity is not correspondingly improved, causing structural inconsistency. This, in turn, exacerbates the noise problem due to the unreasonable increase in the size of the housing, affecting the quietness performance of the compressor. Therefore, in this embodiment, by setting the above-mentioned ratio range, the problem of reduced rigidity of the lower housing 20 due to uneven body proportions can be effectively reduced.

[0051] Furthermore, by maintaining the ratio of the height to the length of the lower housing 20 between 0.68 and 0.7, the internal space layout of the lower housing 20 can be optimized while ensuring its structural stability and rigidity, thereby enhancing the overall operating efficiency and noise reduction performance of the compressor. Specifically, if the ratio is less than 0.68, it means that the vertical dimension of the lower housing 20 is significantly smaller than its length. This results in insufficient vertical rigidity of the lower housing 20 structure, making it prone to deformation under vertical loads during compressor operation. This affects the compressor's sealing performance and operational stability, increasing vibration and noise. Conversely, when the ratio exceeds 0.7, the height of the lower housing 20 is too large relative to its length. Although vertical rigidity is enhanced, longitudinal rigidity and structural stability must be sacrificed, causing the compressor to wobble easily in the longitudinal direction and increasing operating noise.

[0052] Specifically, the inner surface of the upper shell 10 has multiple limiting protrusions, which are symmetrically distributed on both sides of the upper shell 10 along its length. In this embodiment, the symmetrical distribution of the limiting protrusions not only enhances the stability of the internal structure of the upper shell 10, but also effectively disperses the external forces acting on the shell by forming a balanced support layout, reducing local stress concentration and thus improving the overall deformation resistance of the upper shell 10. In addition, these limiting protrusions can also form a more precise fit with the lower shell 20 or internal components, limiting the displacement of internal components during operation and avoiding additional vibration and noise caused by component shaking.

[0053] like Figure 9As shown, the plurality of limiting protrusions include a first protrusion 11, a second protrusion 12, a third protrusion 13, and a fourth protrusion 14. The first protrusion 11 and the second protrusion 12 are symmetrically distributed on both sides of the upper shell 10 along the length direction of the upper shell 10, and the third protrusion 13 and the fourth protrusion 14 are symmetrically distributed on both sides of the upper shell 10 along the length direction of the upper shell 10. The side of the first protrusion 11, the second protrusion 12, the third protrusion 13, and the fourth protrusion 14 facing the center of the upper shell 10 all have a limiting chamfer. The ratio of the limiting chamfer of the first protrusion 11 and the second protrusion 12 is equal to the ratio of the limiting chamfer of the third protrusion 13 and the fourth protrusion 14. Specifically, in Figure 9 In the diagram, A1 represents the limiting chamfer of the first protrusion 11, A2 represents the limiting chamfer of the second protrusion 12, A3 represents the limiting chamfer of the third protrusion 13, and A4 represents the limiting chamfer of the fourth protrusion 14.

[0054] By providing a first protrusion 11, a second protrusion 12, a third protrusion 13, and a fourth protrusion 14 on the inner surface of the upper shell 10, and symmetrically distributing these protrusions along the length of the upper shell 10 on both sides, a stable internal support structure is formed, thereby improving the overall rigidity of the shell. Furthermore, the symmetrically distributed limiting protrusions are equivalent to constructing a set of balanced reinforcing ribs within the shell, effectively dispersing the external forces borne by the upper shell 10 during operation, reducing force concentration, and thus lowering local stress, preventing deformation and damage to the shell due to uneven stress.

[0055] Furthermore, in this embodiment, the design of the limiting chamfer is equivalent to introducing a small bevel inside the shell. When contacting and constraining internal components, it can smoothly transition the contact pressure, avoiding sharp stress concentration, thereby reducing potential structural damage and improving the durability and lifespan of the entire upper shell 10 assembly. More importantly, the equal ratio of the limiting chamfer ensures the force balance and structural consistency on both sides of the upper shell 10, effectively preventing shell deformation or torsion caused by uneven force on one side. This further strengthens the longitudinal stiffness and lateral stability of the upper shell 10, enabling it to better resist various forms of external force intrusion when facing complex operating environments, maintain its structural integrity, and reduce noise and energy efficiency loss caused by structural deformation.

[0056] The inner surface of the lower housing 20 has multiple support protrusions, which are symmetrically distributed on both sides of the lower housing 20 along its length. These protrusions interact with the limiting protrusions of the upper housing 10 and other internal components to form a stable positioning and support system. This ensures precise fit and tight connection between the housing components, further enhancing the rigidity of the entire housing assembly and enabling the compressor to maintain high stability during high-speed operation. The symmetrical distribution of the support protrusions also promotes balanced support for the internal components in all directions, preventing housing tilting or deformation caused by excessive force on one side, reducing additional vibration and noise, and contributing to improved compressor quietness.

[0057] like Figure 10 As shown, the multiple support protrusions include a fifth protrusion 21, a sixth protrusion 22, a seventh protrusion 23, and an eighth protrusion 24. The fifth protrusion 21 and the sixth protrusion 22 are symmetrically distributed on both sides of the lower shell 20 along the length direction of the lower shell 20, and the seventh protrusion 23 and the eighth protrusion 24 are symmetrically distributed on both sides of the lower shell 20 along the length direction of the lower shell 20. The height of the fifth protrusion 21 is the same as the height of the sixth protrusion 22, and the height of the seventh protrusion 23 is the same as the height of the eighth protrusion 24.

[0058] In this embodiment, the fifth protrusion 21, the sixth protrusion 22, the seventh protrusion 23, and the eighth protrusion 24 arranged on the inner surface of the lower shell 20 are symmetrically distributed on both sides along the length of the lower shell 20, and the height of the protrusions on the same side is consistent. This design ensures that the force distribution of the lower shell 20 is balanced in the length direction, avoids shell deformation or rigidity reduction caused by uneven local force, improves the shell's ability to resist external vibration and internal high pressure, and thus effectively reduces the vibration amplitude and noise level of the compressor during operation.

[0059] Furthermore, the fact that the two protrusions at the same end along the length have the same height means that they can provide the same support force. This uniform support force helps maintain the overall structural strength of the lower shell 20 and enhances the lower shell 20's ability to resist longitudinal bending. This allows the lower shell 20 to maintain a stable shape even when subjected to unbalanced external forces from both sides, reducing the risk of interference or damage to internal components that may be caused by shell deformation.

[0060] The height of the fifth protrusion 21 is lower than the height of the seventh protrusion 23, and the height difference between the fifth protrusion 21 and the seventh protrusion 23 is between 1mm and 1.2mm. Specifically, it can be 1mm, 1.1mm, and 1.2mm. This optimizes the positioning of internal components, balances stress distribution, enhances shell rigidity, effectively suppresses vibration, and reduces operating noise. It avoids the situation where the height difference between the two protrusions is too small, affecting the positioning of internal components, or that the height difference is too large, resulting in excessive support on one side of the internal component positioning and insufficient support on the other side. The above design can prevent the shell from tilting or twisting during operation. Specifically, as shown... Figure 11 As shown, in this embodiment, the height difference between the fifth protrusion 21 and the seventh protrusion 23 is represented by Δh.

[0061] In another embodiment of this application, a compressor is also provided, including the housing assembly described above.
