Description

Technical Field

[0001] The utility model belongs to the technical field of compressors and relates to a vibration-damping bracket for installing a liquid storage cylinder of a compressor, a compressor and an air-conditioning system. Background Art

[0002] The large vibration of single-rotor compressors has always been a problem that needs to be paid attention to when designing compressors. When the compressor is in the air-conditioning system, the fixing constraint force of the rubber base is low and the compressor vibrates violently.

[0003] The fixing type of the existing compressor accumulator mainly relies on the bracket for positioning and the clamp for tightening. However, the clamp material is relatively thin and has a certain elasticity. When the vibration is severe, the tightening effect of the clamp will be reduced, resulting in an increase in stress at the bend of the accumulator until it breaks and fails. At the same time, the DC variable frequency single-rotor compressor, its power source motor 3, is installed away from one end of the base, the motor rotor 31 is heat-fitted with the long axis 41 of the pump crankshaft 4, and the motor stator 32 is tightly connected to the inner wall 21 of the compressor cylinder by hot pressing. When the power is turned on, due to the structural characteristics of the 6-pole or 8-pole DC motor, electromagnetic radial vibrations with multiples of the number of poles are generated on the outer circle of the stator 32. The vibration is transmitted through the cylinder 2 and the vibration-damping bracket 10 resistance-welded to the outer wall 22 of the compressor, thereby generating 6 or 8 times frequency noise peaks, which affect the environment. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing liquid reservoir fixing method in the prior art is unstable, and when electromagnetic radial vibration is generated inside the compressor, it will be transmitted through the bracket fixing the liquid reservoir, causing a higher noise peak, and provide a vibration-damping bracket for installing a compressor liquid reservoir, a compressor and an air-conditioning system.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A vibration-damping bracket for installing a compressor liquid storage cylinder comprises a body section, a first extension section and a second extension section are arranged opposite to each other on both sides of the body section, and the first extension section and the second extension section are used to connect with the outer side wall of the compressor;

[0007] The body section is provided with a connecting portion, and the connecting portion is connected to the compressor liquid storage cylinder;

[0008] During assembly, the body section abuts between the compressor and the compressor liquid storage cylinder. When the first extension section and the second extension section are connected to the outer side wall of the compressor, a gap exists between the outer side wall of the compressor and the side wall close to the body section.

[0009] The further improvement of the utility model is:

[0010] In the assembled state, the first extension section and the second extension section are spaced apart from each other up and down along the body section;

[0011] The connecting parts are arranged at two ends of the body segment.

[0012] The end surfaces of the first extension section and the second extension section connected to the outer side wall of the compressor are both arc surfaces;

[0013] The radius of the arc surface is greater than the radius of the outer side wall of the compressor.

[0014] The connection between the first extension section and the main section or the second extension section and the main section is smoothly transitioned, and the smooth transition connection forms an inner transition fillet r, r≤1.

[0015] There is a height difference a between the first extension section and the main body section or between the second extension section and the main body section, and the height difference a satisfies: 0.5mm≤a≤1.5mm.

[0016] The length of the first extension section and the second extension section and the length of the entire vibration-damping bracket satisfy: 0.3≤w1 / w2≤1;

[0017] Wherein, w1 represents the length of the first extension section or the second extension section, and w2 represents the length of the entire vibration-damping bracket.

[0018] The connecting portion is arranged in an inclined state along the end of the body section.

[0019] The connecting portion is provided with a connecting hole or a connecting groove, and the connecting hole or the connecting groove is used for connecting to a compressor liquid storage cylinder.

[0020] A compressor comprises a vibration-damping bracket for installing a compressor liquid storage cylinder as described in any one of the utility models, wherein the vibration-damping bracket is used to connect the compressor and the compressor liquid storage cylinder.

[0021] An air conditioning system comprises the compressor of the utility model.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] The utility model discloses a vibration-damping bracket for installing a compressor liquid storage cylinder. A first extension section and a second extension section are provided, and the connection between the bracket and the compressor is satisfied by the first extension section and the second extension section. Secondly, a connecting portion is provided, and the compressor liquid storage cylinder is connected by the connecting portion to satisfy the fixed connection between the compressor and the compressor liquid storage cylinder. During assembly, when the first extension section and the second extension section are connected to the outer wall of the compressor, a gap exists between the outer wall of the compressor and the side wall close to the body section, so that the body section is kept in a suspended state relative to the outer wall of the compressor, reducing the electromagnetic radial vibration transmitted by the outer cylinder of the compressor, and making the low-frequency resonance performance of the parts better. In addition, the device replaces the clamp clamping method, and the stability of the connection and fixation is higher.

[0024] Furthermore, in the utility model, the end surfaces of the first extension section and the second extension section connected to the outer wall of the compressor are both arc surfaces, which improves the tightness of the connection between the extension section and the outer wall of the compressor.

[0025] Furthermore, in the utility model, the connecting portion is arranged in an inclined state along the end of the main body section. During installation, since the connecting portion is in an inclined state, there is a large gap between the connecting portion and the outer wall of the compressor, which will not interfere with the installation of the liquid storage cylinder.
