A buffer cushion block is provided between the outer side wall of the main housing and the outer side wall of the liquid receiver, and the buffer cushion block is respectively press-fitted to the outer side wall of the main housing and the outer side wall of the liquid receiver. The damping effect of the buffer cushion block reduces the vibration amplitude of the liquid receiver, converts the vibration energy of the liquid receiver into heat energy of the buffer cushion block, which is beneficial to improving the vibration and noise of the liquid receiver and enhancing the fatigue strength of the system and its suction pipe.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the related art, an additional groove needs to be provided on the outer side wall of the liquid receiver as a limiting part to fix the buffer cushion block, which increases the complexity of the processing process.

[0049] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0050] The accumulator is a main vibrating component of the compressor. Since the accumulator is a thin-walled part, the greater the surface vibration of it, the greater the radiated noise. At present, the lowermost end of the accumulator is connected to the compressor housing through an intake pipe. A bracket is arranged at the upper end of the compressor housing, and the upper end of the accumulator is installed on the bracket through a clamping member. In order to reduce the vibration of the accumulator, a rubber pad is usually arranged between the clamping member and the accumulator to absorb the vibration of the accumulator. However, this structure cannot reduce the vibration of the lower part of the accumulator.

[0051] The related art discloses a rotary compressor. The compressor includes a main housing and a liquid receiver communicated with the main housing through a suction pipe. The liquid receiver is fixed to the main housing through a fixing bracket. A buffer cushion block is arranged between the outer side wall of the main housing and the outer side wall of the liquid receiver, and the buffer cushion block is press-fitted to the outer side wall of the main housing and the outer side wall of the liquid receiver respectively. The damping effect of the buffer cushion block reduces the vibration amplitude of the liquid receiver, converts the vibration energy of the liquid receiver into the heat energy of the buffer cushion block, which is beneficial to improving the vibration and noise of the liquid receiver and enhancing the fatigue strength of the system and its suction pipe. However, it is necessary to additionally provide a groove on the outer side wall of the liquid receiver as a limiting part to fix the buffer cushion block, which increases the complexity of the processing process. At the same time, it will also weaken the structural strength of the outer side wall of the liquid receiver. During the vibration of the liquid receiver, the groove may not provide enough friction or locking mechanism to maintain the stable fixation of the buffer cushion block.

[0052] Combined with Figure 1-8 As shown, an embodiment of the present disclosure provides a fixing bracket 100 for fixing a liquid receiver, including a bracket main body 10 and a vibration damping part 20.

[0053] Combined with Figure 1 and Figure 2 As shown, the bracket main body 10 is adapted to be connected to the compressor housing 30, and the bracket main body 10 is adapted to cooperate with the liquid receiver housing 40 to limit the liquid receiver housing 40; the vibration damping part 20 is connected to the bracket main body 10, the vibration damping part 20 is adapted to be arranged between the compressor housing 30 and the liquid receiver housing 40, and the vibration damping part 20 is adapted to abut against both the compressor housing 30 and the liquid receiver housing 40. The vibration damping part 20 is used to reduce the vibration of the liquid receiver.

[0054] The vibration damping component is made of a material with good elasticity and vibration absorption performance. The vibration damping part will deform when subjected to an external force, and after the external force is removed, the vibration damping part can return to its original state. Through deformation, the vibration damping part can effectively absorb the vibration energy generated by the liquid receiver during movement.

[0055] Combined with Figure 8 As shown, the vibration damping part 20 undergoes a deformation displacement x under the action of an external force F.

[0056] Using the fixing bracket 100 for fixing the liquid storage device provided by the embodiments of the present disclosure, the damping part 20 is connected to the bracket main body 10, which can improve the fixing effect of the damping part 20 between the compressor housing 30 and the liquid storage device housing 40 and enhance the stability of the damping part 20. At the same time, since the damping part 20 is fixed by connecting to the bracket main body 10, it is also possible to avoid additionally providing a limiting part in the related art on the liquid storage device housing 40, thereby reducing the production difficulty. During the installation process of the fixing bracket 100, the steps of limiting and installing the damping part 20 are reduced, and the installation process can be simplified. The damping part 20 abuts against both the compressor housing 30 and the liquid storage device housing 40. When the liquid storage device vibrates, the damping part 20 deforms under the action of an external force. In this way, the vibration of the liquid storage device can be effectively absorbed, and the noise radiation caused by the vibration of the liquid storage device can be effectively reduced.

[0057] Optionally, as shown in combination with Figure 1 , Figure 7 and Figure 8 , the damping part 20 includes a first elastic section 21. The first end 211 of the first elastic section is connected to the bracket main body 10 and extends along the axial direction of the liquid storage device housing 40, and is inclined in the direction approaching the liquid storage device housing 40 from the first end 211 to the second end 212 of the first elastic section; wherein, the first end 211 of the first elastic section is adapted to abut against the compressor housing 30, and the second end 212 of the first elastic section is adapted to abut against the liquid storage device housing 40.

[0058] The axial direction of the liquid storage device housing 40 is as indicated by the arrow direction in Figure 1 .

[0059] The first end 211 of the first elastic section is adapted to abut against the compressor housing 30, and the second end 212 of the first elastic section is adapted to abut against the liquid storage device housing 40, so that the first elastic section 21 can form a buffer support between the compressor housing 30 and the liquid storage device housing 40 to achieve a damping effect. The connection of the first end 211 of the first elastic section to the bracket main body 10 and the inclined design from the first end 211 to the second end 212 of the first elastic section in the direction approaching the liquid storage device housing 40 can more effectively absorb and disperse the vibration of the liquid storage device. The damping effect can be enhanced through the first elastic section 21, and the stability of the overall structure can be improved.

[0060] Optionally, as shown in combination with Figure 1 , Figure 7 and Figure 8As shown, the vibration damping part 20 further includes a second elastic section 22. The first end 221 of the second elastic section is connected to the second end 212 of the first elastic section and extends along the axial direction of the liquid reservoir housing 40. From the first end 221 to the second end 222 of the second elastic section, it inclines in a direction away from the liquid reservoir housing 40, so that a convex part 23 is formed at the first end 221 of the second elastic section and the second end 212 of the first elastic section. Among them, the first end 221 of the second elastic section is adapted to abut against the liquid reservoir housing 40, and the second end 222 of the second elastic section is adapted to abut against the compressor housing 30.

[0061] The first end 221 of the second elastic section is adapted to abut against the liquid reservoir housing 40, and the second end 222 of the second elastic section is adapted to abut against the compressor housing 30, so that the second elastic section 22 can form a buffer support between the compressor housing 30 and the liquid reservoir housing 40 to achieve the vibration damping effect. The first end 221 of the second elastic section is connected to the second end 212 of the first elastic section. The inclined design from the first end 211 to the second end 212 of the second elastic section in a direction away from the liquid reservoir housing 40 can more effectively absorb and disperse the vibration of the liquid reservoir. Through the second elastic section 22, the vibration damping effect can be enhanced and the stability of the overall structure can be improved.

[0062] The first end 221 of the second elastic section is connected to the second end 212 of the first elastic section to form a convex part 23, so that a larger elastic deformation space is formed between the convex part 23 and the compressor housing 30, which can adapt to a larger vibration load. This can increase the deformation ability of the vibration damping part 20 and effectively enhance the vibration damping effect.

[0063] Optionally, the vibration damping part 20 is arranged below the bracket main body 10. The first elastic section 21 extends obliquely downward in a direction close to the liquid reservoir housing 40, and the second elastic section 22 extends obliquely downward in a direction away from the liquid reservoir housing 40.

[0064] When the compressor and the liquid reservoir are placed vertically, the axial direction of the liquid reservoir housing 40 is the up and down direction. The bracket main body 10 is matched with the top end of the liquid reservoir housing 40 to limit the liquid reservoir housing 40. The vibration damping part 20 is arranged below the bracket main body 10 and is adapted to absorb the vibration below the liquid reservoir.

[0065] Optionally, in combination Figure 1 and Figure 7 and Figure 8 As shown, the second end 222 of the second elastic section is a free end. Under the action of an external force, the convex part 23 moves towards the compressor housing 30, and the second end 222 of the second elastic section moves along the surface of the compressor housing 30.

[0066] When the convex part 23 is subjected to an external force from the liquid reservoir, the convex part 23 moves towards the compressor housing 30. The second end 222 of the second elastic section moves along the surface of the compressor housing 30, which can increase the deformation degree of the vibration damping part 20 and more effectively absorb the vibration of the liquid reservoir.

[0067] Optionally, under the action of an external force, the convex part 23 moves towards the compressor housing 30, and the second end 222 of the second elastic section moves towards the bottom end 31 of the compressor housing.

[0068] The second elastic section 22 extends towards the bottom end 31 of the compressor housing. When the convex part 23 is subjected to an external force from the liquid reservoir, the convex part 23 moves towards the compressor housing 30. The second end 222 of the second elastic section in contact with the compressor housing 30 can move towards the bottom end 31 of the compressor housing, so that the convex part 23 deforms towards the bottom end 31 of the compressor housing, which can effectively absorb the vibration energy at the bottom end 41 of the liquid reservoir housing, thereby effectively reducing the noise radiation of the liquid reservoir. The bottom end 41 of the liquid reservoir housing is connected to the compressor housing 30 through the intake pipe 42, and the deformation of the convex part 23 towards the bottom end 31 of the compressor housing can also reduce the influence of vibration on the intake pipe 42.

[0069] Optionally, in combination Figure 4 and Figure 5 as shown, the convex part 23 includes an arc surface 231, and the arc surface 231 is adapted to fit with the liquid reservoir housing 40.

[0070] The convex part 23 fits with the liquid reservoir housing 40 through the arc surface 231, and can form a tight envelope contact with the surface of the liquid reservoir housing 40, providing a uniform and stable support for the liquid reservoir housing 40. In this way, the vibration of the liquid reservoir housing 40 can be more evenly absorbed and dispersed, thereby improving the vibration damping effect on the liquid reservoir.

[0071] Optionally, in combination Figure 4 and Figure 5 as shown, the convex part 23 includes a plane 232, and the plane 232 is adapted to abut against the liquid reservoir housing 40.

[0072] The convex part 23 abuts against the liquid reservoir housing 40 through the plane 232, which can provide a stable support surface and can maintain a stable position where the convex part 23 abuts against the liquid reservoir housing 40. At the same time, the design and manufacture of the plane 232 are relatively simple, which can reduce the production cost and complexity.

[0073] Optionally, in combination Figure 2 and Figure 3As shown, the bracket main body 10 includes a connecting portion 11, an extending portion 12, and an outer end portion 13. The connecting portion 11 is connected to the vibration damping portion 20 and is adapted to be connected to the compressor housing 30; the extending portion 12 is connected to an end portion of the connecting portion 11 along the circumferential direction of the accumulator housing 40 and is adapted to abut against the accumulator housing 40; the outer end portion 13 is connected to one end of the extending portion 12 along the circumferential direction of the accumulator housing 40 away from the connecting portion 11, and the outer end portion 13 is adapted to be connected to the clamp member 50 to limit the accumulator housing 40.

[0074] The connecting portion 11 serves as a connection point between the fixed bracket 100 and the compressor housing 30, and can firmly mount the fixed bracket 100 on the compressor housing 30. At the same time, the connecting portion 11 also provides support for the vibration damping portion 20, improving the stability of the vibration damping portion 20. The setting of the connecting portion 11 can improve the stability and reliability of the fixed bracket 100.

[0075] The extending portion 12 is connected to an end portion of the connecting portion 11 along the circumferential direction of the accumulator housing 40 and abuts against the accumulator housing 40, and can support and position the accumulator housing 40. The abutment of the extending portion 12 against the accumulator housing 40 can also evenly distribute the force received by the accumulator housing 40, improving the stability of the accumulator housing 40 during operation.

[0076] The outer end portion 13 is located at one end of the extending portion 12 away from the connecting portion 11, and can be connected to the clamp member 50 to form a limiting space 51, so that the accumulator housing 40 is firmly limited within the limiting space 51 to prevent the accumulator housing 40 from moving. At the same time, the firm limitation of the accumulator housing 40 within the limiting space 51 can also reduce the vibration of the accumulator and lower the noise.

[0077] Optionally, in combination with Figure 3 As shown, the extending portion 12 includes a first extending section 121 and a second extending section 122. The first extending section 121 and the second extending section 122 are respectively connected to two ends of the connecting portion 11 along the circumferential direction of the accumulator housing 40, and the first extending section 121 and the second extending section 122 are adapted to abut against the accumulator housing 40.

[0078] By respectively connecting the first extending section 121 and the second extending section 122 to two ends of the connecting portion 11 along the circumferential direction of the accumulator housing 40, and both the first extending section 121 and the second extending section 122 can abut against the accumulator housing 40, the contact and support between the fixed bracket 100 and the accumulator housing 40 can be enhanced, improving the structural stability.

[0079] Optionally, in combination with Figure 3As shown, the outer end portion 13 includes a first outer end 131 and a second outer end 132. The first outer end 131 is connected to one end of the first extension segment 121 away from the connecting portion 11, and the second outer end 132 is connected to one end of the second extension segment 122 away from the connecting portion 11. Along the circumferential direction of the liquid storage container housing 40, the first outer end 131, the first extension segment 121, the connecting portion 11, the second extension segment 122, and the second outer end 132 are connected in sequence.

[0080] The first outer end 131 is connected to one end of the first extension segment 121 away from the connecting portion 11, and the second outer end 132 is connected to one end of the second extension segment 122 away from the connecting portion 11. Both the first outer end 131 and the second outer end 132 can be connected to the clamp member 50 for limiting the liquid storage container housing 40. Along the circumferential direction of the liquid storage container housing 40, the first outer end 131, the first extension segment 121, the connecting portion 11, the second extension segment 122, and the second outer end 132 are connected in sequence, enabling an effective cooperation between the bracket main body 10 and the liquid storage container housing 40, which helps to stably fix the liquid storage container housing 40.

[0081] Along the circumferential direction of the liquid storage container housing 40, the first outer end 131, the first extension segment 121, the connecting portion 11, the second extension segment 122, and the second outer end 132 are connected in sequence. The two ends of the clamp member 50 can be respectively connected to the first outer end 131 and the second outer end 132, so that the fixing bracket 100 and the clamp member 50 can form a firm connection along the circumferential direction of the liquid storage container housing 40, effectively limiting the liquid storage container housing 40.

[0082] Combined Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a bracket assembly, including the fixing bracket 100 and the clamp member 50 as described in any one of the above - disclosed embodiments. The clamp member 50 is respectively connected to the two ends of the bracket main body 10 along the circumferential direction of the liquid storage container housing 40. A limiting space 51 is defined between the clamp member 50 and the bracket main body 10 to limit the liquid storage container housing 40 within the limiting space 51.

[0083] The bracket assembly provided by the embodiment of the present disclosure includes the fixing bracket 100 for fixing the liquid storage container as described in any one of the above - disclosed embodiments, and thus has all the beneficial effects of the fixing bracket 100 for fixing the liquid storage container as described in any one of the above - disclosed embodiments.

[0084] The clamp member 50 is connected to the two ends of the bracket main body 10 along the circumferential direction of the liquid storage container housing 40. A limiting space 51 is formed between the clamp member 50 and the bracket main body 10, which can stably limit the liquid storage container housing 40. Through the combination of the clamp member 50 and the bracket main body 10, the fixing stability of the liquid storage container can be enhanced, and the displacement of the liquid storage container housing 40 caused by vibration or impact can be reduced.

[0085] Optionally, in combination with Figure 1 and Figure 2 As shown, the bracket assembly further includes an elastic gasket 60, and the elastic gasket 60 is adapted to be disposed between the clamp member 50 and the liquid storage container housing 40 and / or between the bracket main body 10 and the liquid storage container housing 40.

[0086] The elastic gasket 60 can be disposed between the clamp member 50 and the liquid storage container housing 40, or between the bracket main body 10 and the liquid storage container housing 40, or can be disposed between both the clamp member 50 and the liquid storage container housing 40 and between the bracket main body 10 and the liquid storage container housing 40. The elastic gasket 60 can absorb vibrations that may occur during the operation of the liquid storage container, achieve vibration reduction and buffering effects, and reduce noise. At the same time, the elastic gasket 60 can protect the liquid storage container housing 40, the bracket main body 10, and the clamp member 50, and extend the service life of the bracket assembly.

[0087] Optionally, in combination with Figure 2 As shown, when the bracket main body 10 includes a connecting portion 11, an extending portion 12, and an outer end portion 13, the elastic gasket 60 is adapted to be disposed between the extending portion 12 and the liquid storage container housing 40.

[0088] The extending portion 12 is adapted to abut against the liquid storage container housing 40, and the elastic gasket 60 is adapted to be disposed between the extending portion 12 and the liquid storage container housing 40, and can absorb vibrations of the liquid storage container housing 40. This can prevent vibrations from being transmitted to the extending portion 12 and improve the vibration reduction effect.

[0089] Optionally, in combination with Figure 2 As shown, when the bracket main body 10 includes a connecting portion 11, an extending portion 12, and an outer end portion 13, the outer end portion 13 is connected to the clamp member 50 so as to define a limiting space 51 between the clamp member 50 and the bracket main body 10.

[0090] The connecting portion 11 is connected to the vibration damping portion 20, the extending portion 12 is connected to an end portion of the connecting portion 11 along the circumferential direction of the liquid storage container housing 40, the outer end portion 13 is connected to an end of the extending portion 12 along the circumferential direction of the liquid storage container housing 40 away from the connecting portion 11, and the outer end portion 13 is connected to the clamp member 50. In this way, the connecting portion 11, the extending portion 12, the outer end portion 13, and the extending portion 12 are connected in sequence, forming a stable limiting space 51, thereby being able to enhance the stability of the liquid storage container housing 40.

[0091] In combination with Figure 1 and Figure 2As shown in the figure, an embodiment of the present disclosure provides a compressor assembly, including a compressor housing 30, a liquid receiver housing 40, and a bracket assembly as described in the above-mentioned disclosed embodiments. The liquid receiver housing 40 is connected to the compressor housing 30; the bracket main body 10 is connected to the compressor housing 30, the liquid receiver housing 40 is disposed in the limiting space 51, and the damping portion 20 abuts against both the compressor housing 30 and the liquid receiver housing 40.

[0092] The compressor provided by the embodiment of the present disclosure includes the bracket assembly described in any one of the above-mentioned disclosed embodiments, and thus has all the beneficial effects of the bracket assembly described in any one of the above-mentioned disclosed embodiments. Through the bracket assembly, the connection between the liquid receiver housing 40 and the compressor housing 30 is made more stable. At the same time, effective vibration isolation of the liquid receiver is achieved through the damping portion 20, which can improve the stability and reliability of the compressor assembly.

[0093] Optionally, in combination with Figure 1 and Figure 7 As shown in the figure, when a convex portion 23 is formed at the first end 221 of the second elastic section and the second end 212 of the first elastic section, along the radial direction of the liquid receiver housing 40, the distance between the vertex 233 of the convex portion and the compressor housing 30 is L1, and the distance between the liquid receiver housing 40 and the compressor housing 30 is L2, where L1 ≥ L2.

[0094] The vertex 233 of the convex portion is the connection point formed by the first end 221 of the second elastic section and the second end 212 of the first elastic section.

[0095] The distance between the vertex 233 of the convex portion and the compressor housing 30 is as shown by L1 in Figure 7 and the distance between the liquid receiver housing 40 and the compressor housing 30 is as shown by L2 in Figure 1 . L1 ≥ L2 makes an interference fit formed between the convex portion 23 and the liquid receiver housing 40. During the vibration of the liquid receiver, the convex portion 23 can effectively generate elastic deformation to absorb the vibration, thereby improving the damping efficiency.

[0096] Optionally, L1 = (1 - 1.3) × L2.

[0097] L1 is greater than or equal to L2 and less than or equal to 1.3 × L2, that is, the distance L1 between the vertex 233 of the convex portion and the compressor housing 30 is defined as 1 to 1.3 times the distance L2 between the liquid receiver housing 40 and the compressor housing 30. This can form an interference fit between the convex portion 23 and the liquid receiver housing 40 while preventing excessive wear between the convex portion 23 and the liquid receiver housing 40, and extending the service life of the fixing bracket 100.

[0098] It can be understood that L1 = L2, L1 = 1.1×L2, L1 = 1.2×L2, or L1 = 1.3×L2.

[0099] Optionally, in combination with Figure 1 As shown, when the first end 221 of the second elastic section and the second end 212 of the first elastic section form a convex portion 23, along the axial direction of the liquid storage container housing 40, the distance between the vertex 233 of the convex portion and the center 14 of the bracket main body is H1, and the distance between the center 14 of the bracket main body and the bottom end 41 of the liquid storage container housing is H2, and H1 = (0.3 - 0.8)×H2.

[0100] The center 14 of the bracket main body, that is, the center position of the bracket main body 10 along the axial direction of the liquid storage container.

[0101] When H1 is greater than or equal to 0.3×H2, the distance between the vertex 233 of the convex portion and the center 14 of the bracket main body is relatively large, so that the convex portion 23 can contact the region with larger vibration at the bottom end 41 of the liquid storage container housing. In this way, the vibration damping portion 20 can more effectively absorb the vibration of the bottom end 41 of the liquid storage container housing, thereby reducing the overall vibration and noise.

[0102] When H1 is less than or equal to 0.8×H2, it can be avoided that the vertex 233 of the convex portion is too close to the bottom end 41 of the liquid storage container housing, and sufficient extension distance is reserved for the second elastic section 22, so that the second end 222 of the second elastic section can better abut against the compressor housing 30. In this way, the vibration damping portion 20 can achieve effective elastic deformation, thereby effectively absorbing the vibration of the liquid storage container. At the same time, since the bracket main body 10 is usually provided in the top region of the liquid storage container housing 40, and H1 is less than or equal to 0.8×H2, the stability of the entire fixing bracket 100 can also be improved by maintaining an appropriate distance between the vertex of the convex portion 23 and the bottom end 41 of the liquid storage container housing.

[0103] H1 = (0.3 - 0.8)×H2 can effectively reduce the vibration of the liquid storage container while improving the stability of the fixing bracket 100, thereby enhancing the stability of the compressor assembly.

[0104] Optionally, the natural frequency of the vibration damping portion 20 is f1, and the resonance frequency of the bottom end of the liquid storage container is f2, and f1 = (0.8 - 1.2)×f2.

[0105] In combination with Figure 8 As shown, the convex portion 23 is subjected to the pressure F formed by the vibration of the liquid storage container, and the external force application direction of the pressure F on the convex portion is as Figure 8 shown. When the convex portion 23 is subjected to the action of the pressure F, the deformation displacement is x.

[0106] The stiffness K of the vibration damping part 20 is K = F / x, and the vibration damping part 20 can be equivalently regarded as a dynamic vibration absorber. The equivalent mass of the accumulator to the vibration damping part 20 is M, and the natural frequency f1 of the vibration damping part 20 is as follows:

[0107]

[0108] When the bottom end of the accumulator resonates, the resonance frequency of the bottom end of the accumulator is denoted as f2.

[0109] f1 = (0.8 - 1.2) × f2, that is, the natural frequency f1 of the vibration damping part 20 is 0.8 to 1.2 times the resonance frequency f2 of the bottom end of the accumulator, which can make the natural frequency of the vibration damping part 20 close to the resonance frequency of the bottom end of the accumulator. In this way, additional vibration absorption capacity can be provided when the accumulator reaches the resonance state, enabling the vibration damping part 20 to better absorb the vibration at the bottom end of the accumulator and improving the effect of vibration reduction and noise reduction.

[0110] It can be understood that it can be f1 = 0.8 × f2, f1 = 0.9 × f2, f1 = f2, f1 = 1.1 × f2, f1 = 1.2 × f2.
