Description

Technical Field

[0001] This application relates to the field of compressor technology, and in particular to a compressor. Background Technology

[0002] A compressor is used to draw in low-pressure gas and output high-pressure gas. The compressor includes a compressor body and a liquid receiver tank. The liquid receiver tank stores and separates the lubricating oil and liquid refrigerant within the compressor body. The liquid receiver tank and the compressor body are connected via rigid piping. During compressor operation, the periodic reciprocating motion of the compressor body's motor and internal components causes vibration. The vibration frequency of the compressor body approaches the natural frequency of the overall structure formed by the compressor body and the liquid receiver tank. This results in increased vibration amplitude due to resonance, leading to increased operating noise. Utility Model Content

[0003] The purpose of this application is to increase the natural frequency of the compressor, prevent the compressor from resonating during operation, and thereby reduce the operating noise of the compressor.

[0004] To achieve the above objectives, this application provides a compressor.

[0005] The compressor according to this application includes: a compressor body; a liquid storage tank disposed on the outer periphery of the compressor body and spaced apart from the compressor body, the compressor body and the liquid storage tank being in communication with each other; a mounting bracket including a connecting plate and a support plate, the connecting plate being connected between the periphery of the compressor body and the periphery of the liquid storage tank, and at least one side of the connecting plate being connected to the support plate in the circumferential direction of the compressor body, and one end of the support plate being connected to the compressor body in the direction from the compressor body to the liquid storage tank, and the other end of the support plate extending toward the liquid storage tank to be connected to the connecting plate; the connecting plate having a mounting surface opposite to the outer peripheral wall of the compressor body, the mounting surface being constructed as an arc surface matching the shape of the outer peripheral wall of the compressor body, the mounting surface being in contact with the outer peripheral wall of the compressor body.

[0006] According to the compressor of this application, the compressor body and the liquid receiver are connected by a connecting plate, and then the connecting plate is supported by a support plate. The support plate can increase the rigidity of the connecting plate, making it less likely for the compressor body and the liquid receiver to move relative to each other after connection. This can increase the natural frequency of the compressor, prevent the compressor from having a resonance effect during operation, and thus reduce the operating noise of the compressor.

[0007] In some examples of this application, the connecting plate includes a first connecting flange, a connecting plate body, and a second connecting flange. The connecting plate body is fixedly connected between the first connecting flange and the second connecting flange. The connecting plate body is fixedly connected to the compressor body. The first connecting flange and the second connecting flange are spaced apart circumferentially along the compressor body. The free ends of the first connecting flange and the second connecting flange, both away from the connecting plate body, extend in a direction from the compressor body toward the liquid storage tank. The free ends of the first connecting flange and the second connecting flange are connected and engaged with the outer peripheral wall of the liquid storage tank. The connecting plate body is non-detachably fixedly connected to the compressor body, and / or the first connecting flange and the liquid storage tank, and the second connecting flange and the liquid storage tank, are non-detachably fixedly connected.

[0008] In some examples of this application, along the circumference of the compressor body, support plates are provided on both sides of the connecting plate, one of the support plates having an angle with the first connecting flange, and the other support plate having an angle with the second connecting flange; the angle between the first connecting flange and the corresponding support plate is α1, and the angle between the second connecting flange and the corresponding support plate is α2, α1 and α2 satisfy the relationship: 25°≤α1≤30°, 25°≤α2≤30°.

[0009] In some examples of this application, the free end of the first connecting flange is spaced apart from the end of the corresponding support plate away from the compressor body, and the distance between the free end of the first connecting flange and the end of the corresponding support plate away from the compressor body is L1; the free end of the second connecting flange is spaced apart from the end of the corresponding support plate away from the compressor body, and the distance between the free end of the second connecting flange and the end of the corresponding support plate away from the compressor body is L2, and L1 and L2 satisfy the relationship: 3mm≤L1≤7mm, 3mm≤L2≤7mm.

[0010] In some examples of this application, the compressor, in its projection in the height direction, is constructed with a straight line that passes through both the central axis of the compressor body and the central axis of the liquid storage tank. The first connecting flange and the second connecting flange are symmetrically arranged on both sides of the symmetrical axis, and the two support plates are symmetrically arranged on both sides of the symmetrical axis. The height direction of the compressor, the central axis of the liquid storage tank, and the central axis of the compressor body are all parallel to each other.

[0011] In some examples of this application, the connecting plate and the two supporting plates are respectively constructed as independent components, or, a transition portion is connected between the first connecting flange and the corresponding supporting plate, and between the second connecting flange and the corresponding supporting plate. The transition portion is constructed as an arc-shaped body protruding from the compressor body to the liquid storage tank, and the mounting bracket is constructed as an integrally formed part.

[0012] In some examples of this application, the outer diameter of the liquid storage tank is smaller than the outer diameter of the compressor body; the outer diameter of the liquid storage tank is D1, and the distance between the free end of the first connecting flange and the free end of the second connecting flange is D2, and D1 and D2 satisfy the relationship: D1 > D2.

[0013] In some examples of this application, the support plate is provided with a first connecting portion, and the connecting plate is provided with a second connecting portion, wherein the first connecting portion and the second connecting portion are detachably connected and engaged.

[0014] In some examples of this application, the thickness of the support plate is t1, the thickness of the connecting plate is t2, and t1 and t2 satisfy the relationship: 0.7≤t1 / t2≤1.3.

[0015] In some examples of this application, the support plate has an overlapping portion at one end near the compressor body, the shape of the overlapping portion matching the shape of the outer peripheral wall of the compressor body, and the overlapping portion abutting against and connecting with the outer peripheral wall of the compressor body.

Detailed Implementation

[0018] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0019] like Figures 1-5 As shown in the embodiment of this application, a compressor 100 is disclosed. The compressor 100 can be installed in a gas delivery system, such as the heat exchange system of an air conditioner or a refrigerator. The compressor 100 is used to draw in low-pressure gas and output high-pressure gas.

[0020] like Figures 1-5 As shown, the compressor 100 according to an embodiment of this application includes: a compressor body 1, a liquid storage tank 2, and a mounting bracket 3. The compressor body 1 serves as the main working part of the compressor 100. The compressor body 1 includes components such as a housing, a core, and a motor. The core is installed inside the housing, and the motor is connected to the core for transmission. The motor drives the core to work, enabling the core to draw in low-pressure gas and output high-pressure gas. The housing allows the compressor body 1 to form a sealed space.

[0021] like Figure 5 As shown, the liquid receiver 2 is located on the outer periphery of the compressor body 1. The liquid receiver 2 is used to store and separate the lubricating oil and liquid refrigerant within the compressor body 1. The liquid receiver 2 is spaced apart from the compressor body 1. In some preferred embodiments, both the liquid receiver 2 and the compressor body 1 are generally cylindrical, and the central axis of the liquid receiver 2 is parallel to the central axis of the compressor body 1. A connecting pipe connects the compressor body 1 and the liquid receiver 2 to allow them to communicate with each other.

[0022] Furthermore, the mounting bracket 3 includes a connecting plate 31 and a support plate 32. The connecting plate 31 connects the periphery of the compressor body 1 and the periphery of the liquid storage tank 2, enabling the compressor body 1 and the liquid storage tank 2 to form an integrated structure, thus sharing a natural frequency. In the circumferential direction of the compressor body 1, at least one side of the connecting plate 31 is connected to the support plate 32. In the direction from the compressor body 1 to the liquid storage tank 2, one end of the support plate 32 is connected to the compressor body 1, and the other end of the support plate 32 extends towards the liquid storage tank 2, abutting and connecting to the connecting plate 31. By using the connecting plate 31 to connect the compressor body 1 and the liquid storage tank 2, and then using the support plate 32 to support the connecting plate 31, the support plate 32 increases the rigidity of the connecting plate 31, making it less prone to relative movement after the compressor body 1 and the liquid storage tank 2 are connected. This increases the natural frequency of the compressor 100, prevents resonance during operation, and reduces the operating noise of the compressor 100.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the connecting plate 31 includes a first connecting flange 311, a connecting plate body 312, and a second connecting flange 313. The connecting plate body 312 is fixedly connected between the first connecting flange 311 and the second connecting flange 313. The connecting plate body 312 is fixedly connected to the compressor body 1. The first connecting flange 311 and the second connecting flange 313 are spaced apart along the circumference of the compressor body 1. The free ends of the first connecting flange 311 and the second connecting flange 313, which are away from the connecting plate body 312, are both extended in the direction from the compressor body 1 toward the liquid storage tank 2. The free ends of the first connecting flange 311 and the second connecting flange 313 are both connected and engaged with the outer peripheral wall of the liquid storage tank 2. By setting a first connecting flange 311 and a second connecting flange 313 on both sides of the connecting plate body 312, a multi-point fixing structure can be formed between the compressor body 1 and the liquid storage tank 2 in the circumferential direction. When the compressor body 1 vibrates, the mounting bracket 3 can effectively disperse and transmit vibration stress. Compared with setting one connecting flange between the compressor body 1 and the liquid storage tank 2, setting multiple connecting flanges can avoid insufficient structural rigidity between the compressor body 1 and the liquid storage tank 2, thereby improving the natural frequency of the compressor 100.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, the connecting plate body 312 has a mounting surface 314 opposite to the outer peripheral wall of the compressor body 1. The mounting surface 314 is constructed as an arc surface that matches the shape of the outer peripheral wall of the compressor body 1, and the mounting surface 314 fits against the outer peripheral wall of the compressor body 1. This arrangement can increase the contact area between the compressor body 1 and the connecting plate 31. When the compressor body 1 vibrates, the vibration stress can be uniformly transmitted along the arc surface, thereby reducing local stress concentration on the connecting plate body 312. This can further improve the overall rigidity and stability of the mounting bracket 3, and further reduce the amplitude increase and noise problems caused by resonance of the compressor 100 during operation.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the connecting plate body 312 is non-detachably fixedly connected to the compressor body 1, and / or, the first connecting flange 311 is non-detachably fixedly connected to the liquid storage tank 2, and the second connecting flange 313 is non-detachably fixedly connected to the liquid storage tank 2. The connecting plate body 312 and the compressor body 1, the first connecting flange 311 and the liquid storage tank 2, and the second connecting flange 313 and the liquid storage tank 2 can all be fixed by welding to achieve the technical effect of non-detachable fixed connection between the corresponding components.

[0026] By fixing the connecting plate body 312 to the compressor body 1, the connecting plate 31 and the compressor body 1 can form an integral structure. A reliable vibration transmission path can be formed between the connecting plate 31 and the compressor body 1, and the connecting plate 31 is not easy to fall off from the outer peripheral wall of the compressor body 1, thereby improving the working reliability of the mounting bracket 3. Similarly, by fixing the first connecting flange 311 to the liquid storage tank 2 and the second connecting flange 313 to the liquid storage tank 2, the connecting plate 31 and the liquid storage tank 2 can form an integral structure. A reliable vibration transmission path can be formed between the connecting plate 31 and the liquid storage tank 2, and the connecting plate 31 is not easy to fall off from the outer peripheral wall of the liquid storage tank 2, thereby improving the working reliability of the mounting bracket 3.

[0027] In some preferred embodiments, the connecting plate body 312 is non-detachably fixedly connected to the compressor body 1, and the first connecting flange 311 and the liquid storage tank 2, as well as the second connecting flange 313 and the liquid storage tank 2, are all non-detachably fixedly connected. This arrangement allows the compressor body 1, the connecting plate 31, and the liquid storage tank 2 to be sequentially connected to form an integrated structure. The connecting plate 31 can prevent the liquid storage tank 2 from shaking relative to the compressor body 1, which helps to reduce the vibration and noise generated during the operation of the compressor 100.

[0028] like Figure 1 , Figure 3 and Figure 4As shown in some embodiments of this application, support plates 32 can be provided on both sides of the connecting plate 31 along the circumference of the compressor body 1. The two support plates 32 jointly support the connecting plate 31, which can make the support effect on the connecting plate 31 more balanced. One of the support plates 32 has an angle with the first connecting flange 311, so that the support plate 32, the first connecting flange 311 and the outer peripheral wall of the compressor body 1 can jointly form a triangular structure. The triangular structure has good stability, which can improve the rigidity of the mounting bracket 3, thereby reducing the deformation of the mounting bracket 3, and further increasing the natural frequency of the compressor 100, which can prevent the compressor 100 from having a resonance effect during operation.

[0029] Furthermore, the other support plate 32 and the second connecting flange 313 have an angle between them. Similarly, the support plate 32, the second connecting flange 313 and the outer peripheral wall of the compressor body 1 together form a triangular structure. This arrangement can improve the rigidity of the mounting bracket 3, thereby reducing the deformation of the mounting bracket 3, and further increasing the natural frequency of the compressor 100, which can prevent the compressor 100 from having a resonance effect during operation.

[0030] Furthermore, such as Figures 2-4 As shown, the included angle between the first connecting flange 311 and the corresponding support plate 32 is α1, and α1 satisfies the relationship: 25°≤α1≤30°. When the included angle between the first connecting flange 311 and the corresponding support plate 32 is less than 25°, the first connecting flange 311 and the corresponding support plate 32 are approximately parallel. When the support plate 32 is supported between the first connecting flange 311 and the outer peripheral wall of the compressor body 1, the direction of the supporting force applied by the support plate 32 to the first connecting flange 311 is close to the direction in which the first connecting flange 311 extends from the compressor body 1 towards the liquid storage tank 2. The lateral (i.e., the thickness direction of the first connecting flange 311) support effect of the support plate 32 on the first connecting flange 311 is poor, which leads to poor rigidity of the mounting bracket 3, making it difficult for the mounting bracket 3 to effectively offset vibration loads.

[0031] When the angle between the first connecting flange 311 and the corresponding support plate 32 is greater than 30°, in the triangular structure formed by the support plate 32, the first connecting flange 311 and the outer peripheral wall of the compressor body 1, the structural dimension of the support plate 32 extending between the outer peripheral wall of the compressor body 1 and the first connecting flange 311 is too long. The support plate 32 itself is prone to bending, and the support effect of the support plate 32 on the first connecting flange 311 is poor, which will also aggravate the vibration and noise problems of the compressor 100.

[0032] Therefore, by setting the included angle between the first connecting flange 311 and the corresponding support plate 32 to 25° to 30°, the structural dimensions of the support plate 32 are more reasonable, and the direction of the supporting force on the first connecting flange 311 is more suitable. After the supporting force on the first connecting flange 311 is decomposed, the first connecting flange 311 can have sufficient supporting strength, which can effectively limit the vibration transmission between the compressor body 1 and the liquid storage tank 2, thereby improving the stability and noise control performance of the compressor 100 during operation.

[0033] And, as Figures 2-4 As shown, the included angle between the second connecting flange 313 and the corresponding support plate 32 is α2, which satisfies the relationship: 25°≤α2≤30°. When the included angle between the second connecting flange 313 and the corresponding support plate 32 is less than 25°, the second connecting flange 313 and the corresponding support plate 32 are approximately parallel. When the support plate 32 supports the second connecting flange 313 and the outer peripheral wall of the compressor body 1, the direction of the supporting force applied by the support plate 32 to the second connecting flange 313 is close to the direction in which the second connecting flange 313 extends from the compressor body 1 towards the liquid storage tank 2. The lateral (i.e., the thickness direction of the second connecting flange 313) support effect of the support plate 32 on the second connecting flange 313 is poor, resulting in poor rigidity of the mounting bracket 3, making it difficult for the mounting bracket 3 to effectively counteract vibration loads.

[0034] When the included angle between the second connecting flange 313 and the corresponding support plate 32 is greater than 30°, in the triangular structure formed by the support plate 32, the second connecting flange 313 and the outer peripheral wall of the compressor body 1, the structural dimension of the support plate 32 extending between the outer peripheral wall of the compressor body 1 and the second connecting flange 313 is too long. The support plate 32 itself is prone to bending, and the support effect of the support plate 32 on the second connecting flange 313 is poor, which will also aggravate the vibration and noise problems of the compressor 100.

[0035] Therefore, by setting the included angle between the second connecting flange 313 and the corresponding support plate 32 to 25° to 30°, the structural dimensions of the support plate 32 are more reasonable, and the direction of the supporting force on the second connecting flange 313 is more suitable. After the supporting force on the second connecting flange 313 is decomposed, the second connecting flange 313 can have sufficient supporting strength, which can effectively limit the vibration transmission between the compressor body 1 and the liquid storage tank 2, thereby improving the stability and noise control performance of the compressor 100 during operation.

[0036] like Figure 3As shown, in some other embodiments of this application, the support plate 32 includes a first support portion 321 and a second support portion 322 connected to each other. The end of the first support portion 321 away from the second support portion 322 is connected to the outer peripheral wall of the compressor body 1, and the end of the second support portion 322 away from the first support portion 321 is abutted and connected to the connecting plate 31. There is an included angle between the first support portion 321 and the second support portion 322, and the second support portion 322 is inclined towards the inner side of the mounting bracket 3 in the direction from near the first support portion 321 to away from the first support portion 321. By pre-bending the support plate 32 to form the first support part 321 and the second support part 322, when the connecting flange (i.e. the first connecting flange 311 or the second connecting flange 313) is squeezed or stretched, the connecting flange drives the second support part 322 to move. The second support part 322 rotates around the connection between the first support part 321 and the second support part 322. The bending resistance of the support plate 32 itself can limit the rotation of the second support part 322, thereby achieving the technical effect of supporting the connecting plate 31.

[0037] like Figure 2 , Figure 3 As shown, in some embodiments of this application, the free end of the first connecting flange 311 is spaced apart from the end of the corresponding support plate 32 away from the compressor body 1. That is, the support plate 32 can support the middle position of the first connecting flange 311. When the first connecting flange 311 is compressed or stretched between the compressor body 1 and the liquid storage tank 2, causing the middle position of the first connecting flange 311 to bend, by using the support plate 32 to support the middle position of the first connecting flange 311, bending of the first connecting flange 311 can be avoided as much as possible, thereby effectively improving the support effect of the support plate 32 on the connecting plate 31.

[0038] Furthermore, the distance between the free end of the first connecting flange 311 and the end of the corresponding support plate 32 furthest from the compressor body 1 is L1, and L1 satisfies the relationship: 3mm≤L1≤7mm. When the distance L1 is less than 3mm, if the first connecting flange 311 is fixed to the support plate 32 and the liquid storage tank 2 by welding, the connection points between the first connecting flange 311 and the support plate 32, and between the first connecting flange 311 and the liquid storage tank 2, will be too close. This will cause the high temperature generated during the welding of the first connecting flange 311 and the support plate 32 to affect the connection point between the first connecting flange 311 and the liquid storage tank 2. The tank body of the liquid storage tank 2 will be prone to secondary deformation, leading to a reduction in the structural strength and rigidity of the liquid storage tank 2, and consequently, making the liquid storage tank 2 prone to breakage and leakage.

[0039] When the interval distance L1 is greater than 7mm, the interval distance between the support plate 32 on the side closer to the first connecting flange 311 and the liquid storage tank 2 is too far. The support effect of the support plate 32 on the liquid storage tank 2 is weakened, which leads to increased vibration of the liquid storage tank 2 when the compressor 100 is running, and increases the operating noise of the compressor 100.

[0040] Therefore, by designing the interval distance L1 to be 3mm to 7mm, the spacing between the connection points of the first connecting flange 311 and the support plate 32, and between the first connecting flange 311 and the liquid storage tank 2, is appropriate. The high temperature generated during the welding connection of the first connecting flange 311 and the support plate 32 does not affect the connection point between the first connecting flange 311 and the liquid storage tank 2, thus preventing secondary deformation of the liquid storage tank 2. This reduces the impact on the structural strength and rigidity of the liquid storage tank 2, improving its operational reliability. Furthermore, when the compressor body 1 vibrates, the support plate 32 effectively supports the first connecting flange 311, strengthening the structural strength of the mounting bracket 3. This improves the fixing effect of the mounting bracket 3 on the liquid storage tank 2, reducing the vibration and operating noise of the compressor 100.

[0041] Furthermore, such as Figure 2 , Figure 3 As shown, the free end of the second connecting flange 313 is spaced apart from the end of the corresponding support plate 32 away from the compressor body 1, and the distance between the free end of the second connecting flange 313 and the end of the corresponding support plate 32 away from the compressor body 1 is L2, which satisfies the relationship: 3mm≤L2≤7mm.

[0042] When the interval distance L2 is less than 3mm, if the second connecting flange 313 and the support plate 32, and the second connecting flange 313 and the liquid storage tank 2 are fixed by welding, the connection between the second connecting flange 313 and the support plate 32, and the connection between the second connecting flange 313 and the liquid storage tank 2 will be too close. This will cause the high temperature generated when the second connecting flange 313 and the support plate 32 are welded to affect the connection between the second connecting flange 313 and the liquid storage tank 2. The tank body of the liquid storage tank 2 is prone to secondary deformation, which will reduce the structural strength and rigidity of the tank body of the liquid storage tank 2, and thus make the liquid storage tank 2 prone to breakage and leakage.

[0043] When the interval distance L2 is greater than 7mm, the interval distance between the support plate 32 on the side closer to the second connecting flange 313 and the liquid storage tank 2 is too far. The support effect of the support plate 32 on the liquid storage tank 2 is weakened, which leads to increased vibration of the liquid storage tank 2 when the compressor 100 is running, and increases the operating noise of the compressor 100.

[0044] Therefore, by designing the interval distance L2 to be 3mm to 7mm, the spacing between the connection points of the second connecting flange 313 and the support plate 32, and between the second connecting flange 313 and the liquid storage tank 2, is appropriate. The high temperature generated during the welding connection of the second connecting flange 313 and the support plate 32 does not affect the connection point between the second connecting flange 313 and the liquid storage tank 2, thus preventing secondary deformation of the liquid storage tank 2. This reduces the impact on the structural strength and rigidity of the liquid storage tank 2, and improves the operational reliability of the liquid storage tank 2. Furthermore, when the compressor body 1 vibrates, the support plate 32 can effectively support the second connecting flange 313, strengthening the structural strength of the mounting bracket 3. This results in better fixation of the mounting bracket 3 to the liquid storage tank 2, reducing the vibration and operating noise of the compressor 100.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown in some embodiments of this application, in the projection of the compressor 100 in the height direction, a symmetry axis 4 is constructed by a straight line passing through the central axis of both the compressor body 1 and the central axis of the liquid storage tank 2. The first connecting flange 311 and the second connecting flange 313 are symmetrically arranged on both sides of the symmetry axis 4, and two support plates 32 are symmetrically arranged on both sides of the symmetry axis 4. The height direction of the compressor 100, the central axis of the liquid storage tank 2, and the central axis of the compressor body 1 are all parallel to each other. That is, on both sides of the symmetry axis 4, the mounting bracket 3 is constructed as an axisymmetric structure, with the design values ​​of the included angle α1 and included angle α2 being equal, and the design values ​​of the interval distance L1 and interval distance L2 being equal. When the compressor body 1 vibrates, this design allows the vibration load to be evenly distributed on the mounting bracket 3, avoiding excessive force on one side of the mounting bracket 3 and causing bending problems. This enhances the overall structural balance and rigidity of the mounting bracket 3, and further improves the stability and noise control performance of the compressor 100 during operation.

[0046] like Figures 2-4 As shown, in some embodiments of this application, the outer diameter of the liquid storage tank 2 is smaller than the outer diameter of the compressor body 1. The outer diameter of the liquid storage tank 2 is D1, and the distance between the free end of the first connecting flange 311 and the free end of the second connecting flange 313 is D2. D1 and D2 satisfy the relationship: D1 > D2. For example, in Figure 1In the illustrated embodiment, the outer diameter D1 of the liquid storage tank 2 is designed to be 89.7 mm, and the distance D2 between the free end of the first connecting flange 311 and the free end of the second connecting flange 313 is designed to be 86 mm. When the liquid storage tank 2 is installed with the mounting bracket 3, the liquid storage tank 2 can first extend into the opening formed by the first connecting flange 311 and the second connecting flange 313, and the liquid storage tank 2 simultaneously contacts the first connecting flange 311 and the second connecting flange 313. The first connecting flange 311 and the second connecting flange 313 can jointly pre-position the liquid storage tank 2 to limit the positional deviation when the liquid storage tank 2 is connected and fitted with the connecting plate 31, thereby improving the connection accuracy between the liquid storage tank 2 and the connecting plate 31, and thus improving the product consistency of the compressor 100.

[0047] In other embodiments of this application, the support plate 32 may be provided with a first connecting portion, and the connecting plate 31 may be provided with a second connecting portion, with the first connecting portion and the second connecting portion being detachably connected. The connection method between the first connecting portion and the second connecting portion includes, but is not limited to, screw connection, hinge connection, plug connection, or snap-fit ​​connection. For example, the first connecting portion may be provided with a first connecting hole, and the second connecting portion may be provided with a second connecting hole. Fasteners (e.g., bolts) pass through the first connecting hole and the second connecting hole in sequence to detachably connect the support plate 32 and the connecting plate 31 together. By detachably connecting the support plate 32 and the connecting plate 31, the assembly position between the support plate 32 and the connecting plate 31 is easier to adjust. The support plate 32 and the connecting plate 31 can be first connected to the compressor body 1 and the liquid storage tank 2, and then connected to each other. This reduces the installation difficulty of the mounting bracket 3 between the compressor body 1 and the liquid storage tank 2, thereby improving the assembly efficiency of the compressor 100.

[0048] like Figure 1 , Figure 3 As shown, in some embodiments of this application, by setting the support plate 32 and the connecting plate 31 as independent components, the thickness of the support plate 32 and the thickness of the connecting plate 31 can be set to different sizes to adjust the physical properties of the support plate 32 and the connecting plate 31, thereby adjusting the overall rigidity of the mounting bracket 3. The connecting plate 31 and the support plate 32 can respectively meet the connection requirements and noise suppression requirements between the compressor body 1 and the liquid storage tank 2.

[0049] In some specific embodiments of this application, the thickness of the support plate 32 is t1, and the thickness of the connecting plate 31 is t2. t1 and t2 satisfy the relationship: 0.7 ≤ t1 / t2 ≤ 1.3. When the thickness t1 of the support plate 32 is too small, and / or the thickness t2 of the connecting plate 31 is too large, resulting in a ratio between the thickness t1 of the support plate 32 and the thickness t2 of the connecting plate 31 being less than 0.7, the structural strength of the support plate 32 is too low and it is difficult to support the connecting plate 31. The support plate 32 does not significantly improve the overall rigidity of the mounting bracket 3, resulting in a low increase in the natural frequency of the compressor 100. The compressor 100 is prone to resonance during operation, leading to higher noise levels and affecting the user experience.

[0050] When the thickness t1 of the support plate 32 is too large and / or the thickness t2 of the connecting plate 31 is too small, resulting in a ratio between the thickness t1 of the support plate 32 and the thickness t2 of the connecting plate 31 being greater than 1.3, the connecting plate 31 is prone to deformation, which will affect the connection between the compressor body 1 and the liquid storage tank 2. This will cause the liquid storage tank 2 to easily shake relative to the compressor body 1, resulting in a lower increase in the natural frequency of the compressor 100. The compressor 100 is prone to resonance during operation, which in turn leads to greater noise from the compressor 100 and affects the user experience of the compressor 100.

[0051] Therefore, by designing the ratio between the thickness dimension t1 of the support plate 32 and the thickness dimension t2 of the connecting plate 31 to be 0.7 to 1.3, the supporting effect of the support plate 32 and the connecting effect of the connecting plate 31 can be more balanced, which can effectively improve the overall rigidity of the mounting bracket 3, thereby increasing the natural frequency of the compressor 100. This can make the operating frequency of the compressor 100 far away from the natural frequency of the compressor 100, which helps to prevent the compressor 100 from having a resonance effect.

[0052] like Figure 1 , Figure 3 and Figure 4As shown in some embodiments of this application, the end of the support plate 32 near the compressor body 1 may be provided with an overlapping portion. The shape of the overlapping portion matches the shape of the outer peripheral wall of the compressor body 1, and the overlapping portion abuts against and connects with the outer peripheral wall of the compressor body 1. That is, the support plate 32 can be connected to the outer peripheral wall of the compressor body 1 through the overlapping portion. By utilizing the abutting fit between the overlapping portion and the outer peripheral wall of the compressor body 1, the contact area between the support plate 32 and the compressor body 1 can be increased, that is, the connection area between the support plate 32 and the compressor body 1 can be increased. Furthermore, by making the shape of the overlapping portion match the shape of the outer peripheral wall of the compressor body 1, the overlapping portion can mutually limit the movement of the overlapping portion relative to the compressor body 1, thereby restricting the movement of the overlapping portion relative to the compressor body 1. This arrangement further improves the overall rigidity of the mounting bracket 3 and improves the connection strength and reliability between the support plate 32 and the compressor body 1.

[0053] like Figure 4 As shown, in some specific embodiments of this application, the support plate 32 and the connecting flange (i.e., the first connecting flange 311 or the second connecting flange 313) are spaced apart along the circumference of the compressor body 1. A transition portion 33 is connected between the support plate 32 and the connecting flange. The transition portion 33 is arc-shaped and protrudes from the compressor body 1 toward the liquid storage tank 2. This arrangement allows the mounting bracket 3 to be constructed as an integral structure, which can simplify the production process of the mounting bracket 3 and improve the connection reliability between the support plate 32 and the connecting flange.

[0054] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
