[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0034] According to the first aspect of the present application, please refer to Figure 1 , the present disclosure provides a compressor vibration damping structure. The compressor vibration damping structure includes an oil return partition 1, a static disk 2, and a vibration damping assembly 3. The oil return partition 1 forms an installation cavity 11. At least a part of the static disk 2 is disposed in the installation cavity 11. The static disk 2 can move relative to the oil return partition 1. The vibration damping assembly 3 is disposed in the installation cavity 11, and the vibration damping assembly 3 is located between the static disk 2 and the oil return partition 1.

[0035] It can be understood that by disposing the vibration damping assembly 3 between the static disk 2 and the oil return partition 1, when the static disk 2 moves relative to the oil return partition 1, the vibration damping assembly 3 can reduce the amplitude of vibration of the static disk 2, reduce the vibration transmitted from the static disk 2 to the oil return partition 1, and further reduce the high-frequency vibration of the compressor, effectively reducing the noise generated by the compressor. At the same time, the vibration damping assembly 3 can also reduce the force when the static disk 2 collides with the oil return partition 1, effectively reducing the knocking noise and effectively improving the noise problem of the compressor.

[0036] In the related art, during the actual operation of the compressor, the stationary disk 2 is forced to vibrate axially and radially. The stationary disk 2 will generate high-frequency vibration and collide with the oil return partition 1 to produce a knocking sound, resulting in high-frequency abnormal sound and knocking sound emitted by the compressor, and the noise is relatively large. However, in the present application, by providing a vibration damping component 3 between the stationary disk 2 and the oil return partition 1, on the one hand, the vibration damping component 3 can suppress the high-frequency vibration of the stationary disk 2 and reduce the vibration amplitude of the stationary disk 2. On the other hand, the vibration damping component 3 can play a buffering role between the stationary disk 2 and the oil return partition 1, reducing the knocking sound generated when the stationary disk 2 collides with the oil return partition 1, thereby effectively reducing the noise of the compressor.

[0037] In some examples, the vibration damping component 3 is, for example, a vibration damping damper or a spring, etc. It should be noted that only an example of the vibration damping component 3 is given here, and no special limitation is made.

[0038] In some examples, the stationary disk 2 can move relative to the oil return partition 1, indicating that there are certain gaps between the stationary disk 2 and the bottom wall and side wall of the installation cavity 11, so as to facilitate the movement of the stationary disk 2 relative to the oil return partition 1. The vibration damping component 3 can be provided between the stationary disk 2 and the bottom wall of the installation cavity 11, or can be provided between the stationary disk 2 and the side wall surface of the installation cavity 11, or can also be provided between the stationary disk 2 and the bottom wall of the installation cavity 11 and between the stationary disk 2 and the side wall of the installation cavity 11 at the same time.

[0039] In some embodiments, the vibration damping component 3 is an elastic member. When the stationary disk 2 moves towards the oil return partition 1, the stationary disk 2 squeezes the vibration damping component 3 to cause the vibration damping component 3 to deform. When the stationary disk 2 moves away from the oil return partition 1, the vibration damping component 3 provides a deformation restoring force to the stationary disk 2.

[0040] It can be understood that during the operation of the compressor, the stationary disk 2 will reciprocate relative to the oil return partition 1. And the vibration damping component 3 is located between the stationary disk 2 and the oil return partition 1. When the stationary disk 2 moves towards the oil return partition 1, the stationary disk 2 will squeeze the vibration damping component 3. Since the vibration damping component 3 is an elastic member, the vibration damping component 3 will deform under the action of the squeezing force. When the stationary disk 2 moves away from the oil return partition 1, the vibration damping component 3 will gradually recover the deformation and provide a deformation restoring force to the stationary disk 2, so that the stationary disk 2 returns to the correct position. That is to say, the elastic vibration damping component 3 can give a restoring moment to the stationary disk 2 when the stationary disk 2 moves away from the oil return partition 1 to prevent the stationary disk 2 from tilting.

[0041] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , along the axial direction of the stationary disk 2, the stationary disk 2 includes a first end face 21 facing the oil return partition 1, and the oil return partition 1 includes a connecting face 12 opposite to the first end face 21, and the vibration damping component 3 is provided between the first end face 21 and the connecting face 12.

[0042] It is understandable that when the stationary disk 2 moves axially, the damping component 3 between the first end face 21 of the stationary disk 2 and the connection face 12 of the oil return partition plate 1 can reduce the vibration of the stationary disk 2, so as to reduce the vibration transmitted from the stationary disk 2 to the oil return partition plate 1, and further effectively reduce the vibration of the entire compressor, so as to reduce the noise of the compressor. At the same time, the damping component 3 can also reduce the force of the stationary disk 2 hitting the oil return partition plate 1. That is, the damping component 3 can play a role in damping and reducing the knocking sound when the stationary disk 2 moves axially.

[0043] In some examples, the damping component 3 has a certain elasticity. Since the damping component 3 is located on the axial movement path of the stationary disk 2, when the stationary disk 2 moves axially away from the oil return partition plate 1, the damping component 3 can also provide a restoring moment for the stationary disk 2 to prevent the stationary disk 2 from tilting radially.

[0044] In some examples, along the axial direction of the stationary disk 2, the stationary disk 2 includes a first end face 21 and a second end face, and the second end face is adapted to be connected to the moving disk.

[0045] In some embodiments, referring to Figure 2 , the damping component 3 includes a plurality of first damping members 31, and the plurality of first damping members 31 are uniformly arranged along the circumferential direction of the stationary disk 2 between the first end face 21 and the connection face 12.

[0046] It is understandable that by arranging a plurality of first damping members 31 between the first end face 21 of the stationary disk 2 and the connection face 12 of the oil return partition plate 1, the plurality of first damping members 31 can all play a damping effect to effectively reduce the vibration of the stationary disk 2. At the same time, the plurality of first damping members 31 are uniformly arranged, ensuring that the forces exerted on the stationary disk 2 by the plurality of first damping members 31 are uniform, and can prevent the stationary disk 2 from tilting when moving relative to the oil return partition plate 1.

[0047] In some examples, the first damping member 31 has a certain elasticity. Since the first damping member 31 is located on the axial movement path of the stationary disk 2, when the stationary disk 2 moves axially away from the oil return partition plate 1, the first damping member 31 can also provide a restoring moment for the stationary disk 2, and since the plurality of first damping members 31 are uniformly distributed, the uniformity of the restoring moment received by the stationary disk 2 is ensured.

[0048] In some embodiments, referring to Figure 4 , along the axial direction of the stationary disk 2, the stationary disk 2 includes a first end facing the oil return partition plate 1, the damping component 3 is an annular damping member, one end of the annular damping member is sleeved on the first end of the stationary disk 2, and the other end of the annular damping member protrudes from the first end of the stationary disk 2.

[0049] It can be understood that the annular vibration damper is sleeved on the stator plate 2 so that the annular vibration damper is connected to the stator plate 2, and the first end of the stator plate 2 can play a certain limiting role on the annular vibration damper. At the same time, the other end of the annular vibration damper protrudes from the first end of the stator plate 2, so that the other end of the annular vibration damper can abut against the oil return baffle 1, that is, when the stator plate 2 moves toward the oil return baffle 1, the other end of the annular vibration damper will first abut against the oil return baffle 1, so that the annular vibration damper can reduce the knocking force between the stator plate 2 and the oil return baffle 1.

[0050] In some examples, a step surface is formed on the side wall surface of the first end of the stator plate 2, and one end of the annular vibration damper is sleeved on the first end of the stator plate 2 and abuts against the step surface. The step surface can limit the annular vibration damper and prevent one end of the annular vibration damper from moving in a direction away from the oil return baffle 1.

[0051] In some examples, along the axial direction of the stator plate 2 , the stator plate 2 includes a first end and a second end, and the second end of the stator plate 2 protrudes out of the mounting cavity 11 and is suitable for connecting with the moving plate.

[0052] In some embodiments, see Figure 1 and Figure 5 The vibration reduction assembly 3 includes a second vibration reduction member 32 , and the second vibration reduction member 32 is arranged between the side wall surface of the installation cavity 11 and the stator 2 .

[0053] It can be understood that the second vibration damper 32 can reduce the vibration of the stator 2, reduce the vibration transmitted from the stator 2 to the side wall of the installation cavity 11, and thus reduce the vibration of the compression molding machine, and the second vibration damper 32 can also reduce the rigid collision between the stator 2 and the side wall of the installation cavity 11, that is, reduce the rigid collision between the stator 2 and the oil return baffle 1, effectively suppress the knocking noise, and effectively reduce the noise generated by the compressor. At the same time, the second vibration damper 32 is arranged between the side wall of the stator 2 and the side wall of the installation cavity 11, and the second vibration damper 32 can prevent the stator 2 from tilting.

[0054] In some examples, the stator plate 2 can move relative to the oil return baffle 1, and the stator plate 2 has a certain degree of freedom of movement in the radial direction, that is, the direction from the side wall of the stator plate 2 to the side wall of the installation cavity 11. In this application, the second vibration damper 32 is disposed between the side wall of the stator plate 2 and the side wall of the installation cavity 11, and the second vibration damper 32 is used to reduce vibration, and the stator plate 2 is prevented from tilting toward the side wall of the installation cavity 11 as much as possible.

[0055] In some embodiments, see Figure 1 The side wall surface of the stator plate 2 includes a first connecting portion 22 and a second connecting portion 23 . The first connecting portion 22 is connected to the oil return baffle 1 through a second vibration damper 32 , and the second connecting portion 23 abuts against the oil return baffle 1 .

[0056] It can be understood that the second vibration damping member 32 connects the first connecting portion 22 of the stationary disk 2 and the oil return partition 1, and the second connecting portion 23 of the stationary disk 2 can directly abut against the oil return partition 1, so that the second vibration damping member 32 cannot completely wrap the side wall surface of the stationary disk 2, resulting in a certain rigid contact area between the oil return partition 1 and the stationary disk 2, so as to avoid plastic deformation or even rupture of the second vibration damping member 32 when the stationary disk 2 moves radially, ensuring the stable operation of the compressor.

[0057] In some embodiments, a first installation groove is formed on the side wall surface of the stationary disk 2, and the second vibration damping member 32 is installed in the first installation groove and abuts against the side wall surface of the installation cavity 11.

[0058] It can be understood that by providing the first installation groove on the side wall surface of the stationary disk 2, the first installation groove can play a limiting role on the second vibration damping member 32, enabling the second vibration damping member 32 to be stably connected to the stationary disk 2 and enabling the second vibration damping member 32 to be stably located between the stationary disk 2 and the side wall surface of the installation cavity 11.

[0059] In some examples, one end of the second vibration damping member 32 is inserted into the first installation groove, the other end of the second vibration damping member 32 protrudes from the first installation groove, and the second end of the second vibration damping member 32 is adapted to abut against the side wall surface of the installation cavity 11.

[0060] In some embodiments, refer to Figure 1 , a second installation groove 111 is formed on the side wall surface of the installation cavity 11, and the second vibration damping member 32 is installed in the second installation groove 111 and abuts against the side wall surface of the stationary disk 2.

[0061] It can be understood that by providing the second installation groove 111 on the side wall surface of the installation cavity 11, the second installation groove 111 can play a limiting role on the second vibration damping member 32, enabling the second vibration damping member 32 to be stably connected to the oil return partition 1 and enabling the second vibration damping member 32 to be stably located between the stationary disk 2 and the side wall surface of the installation cavity 11.

[0062] In some examples, one end of the second vibration damping member 32 is inserted into the second installation groove 111, the other end of the second vibration damping member 32 protrudes from the second installation groove 111, and the second end of the second vibration damping member 32 is adapted to abut against the side wall surface of the installation cavity 11.

[0064] It can be understood that the compressor of the present application arranges the vibration damping component 3 between the stationary disk 2 and the oil return partition plate 1. When the stationary disk 2 moves relative to the oil return partition plate 1, the vibration damping component 3 can reduce the amplitude of vibration of the stationary disk 2, reduce the vibration transmitted from the stationary disk 2 to the oil return partition plate 1, thereby reducing the high-frequency vibration of the compressor and effectively reducing the noise generated by the compressor. At the same time, the vibration damping component 3 can also reduce the impact force when the stationary disk 2 collides with the oil return partition plate 1, effectively reduce the knocking noise, and effectively improve the noise problem of the compressor.

At the same time, the vibration damping component 3 can also reduce the impact force when the stationary disk 2 collides with the oil return partition plate 1, effectively reduce the knocking noise, effectively improve the noise problem of the compressor, and thereby effectively reduce the operating noise of the air conditioner.

[0068] It can be understood that the vehicle includes an air conditioner, and the air conditioner includes a compressor. The compressor arranges the vibration damping component 3 between the stationary disk 2 and the oil return partition plate 1. When the stationary disk 2 moves relative to the oil return partition plate 1, the vibration damping component 3 can reduce the amplitude of vibration of the stationary disk 2, reduce the vibration transmitted from the stationary disk 2 to the oil return partition plate 1, thereby reducing the high-frequency vibration of the compressor and effectively reducing the noise generated by the compressor. At the same time, the vibration damping component 3 can also reduce the impact force when the stationary disk 2 collides with the oil return partition plate 1, effectively reduce the knocking noise, effectively improve the noise problem of the compressor, and thereby effectively reduce the operating noise of the air conditioner, thus reducing the operating noise of the vehicle.
