Description

Technical Field

[0001] The utility model relates to the technical field of dynamic scroll plates, and in particular, to a dynamic scroll plate assembly, a pump body assembly and a compressor. Background Art

[0002] At present, as a positive displacement compressor, a scroll compressor provides power through the volume change of a compression chamber formed between a dynamic scroll plate and a static scroll plate.

[0003] However, when the pump body of the scroll compressor compresses the refrigerant, a large axial force will be generated. The axial force will cause a tendency for the dynamic scroll plate and the static scroll plate to separate axially, thereby causing pump body leakage. At the same time, since the axial force received by the base plate of the dynamic scroll plate is not evenly distributed along the circumference of the dynamic scroll plate, an overturning moment will be generated on the dynamic scroll plate, resulting in the inability of the dynamic scroll plate to maintain a translational state. The tooth part of the dynamic scroll plate will tilt, and further cause friction between the tooth part of the dynamic scroll plate and the tooth part of the static scroll plate, thereby affecting the service life and reliability of the dynamic scroll plate and the static scroll plate, increasing the noise and vibration generated by the compressor.

[0049] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0050] As Figures 1 to 7 shown, the first embodiment of the present utility model provides a moving scroll assembly. The moving scroll assembly includes a bracket 20 and a moving scroll 10 movably arranged on the bracket 20. An installation groove 30 is arranged on the moving scroll 10, and a sliding groove 40 opposite to the installation groove 30 is arranged on the bracket 20. The moving scroll assembly further includes an abutting member 50 and an elastic member 70. The abutting member 50 includes a connected connecting portion 51 and an abutting portion 52. The connecting portion 51 is arranged to be adapted to the installation groove 30; at least part of the connecting portion 51 is movably arranged in the installation groove 30, and the abutting portion 52 extends out of the installation groove 30 and is arranged to be adapted to the sliding groove 40. The elastic member 70 is arranged in the installation groove 30; the elastic member 70 is connected to or abuts against the connecting portion 51 so that at least part of the abutting portion 52 remains in abutment with the groove wall of the sliding groove 40.

[0051] By adopting the moving scroll disk assembly provided in the first embodiment of the present utility model, through the arrangement of the abutting member 50 and the elastic member 70, at least part of the connecting portion 51 is movably arranged in the installation groove 30, and in cooperation with the arrangement of the elastic member 70, at least part of the abutting portion 52 connected to the connecting portion 51 is kept in abutment with the groove wall of the sliding groove 40. Through such an arrangement, since the connecting portion 51 is arranged to be adapted to the installation groove 30 and the abutting portion 52 is arranged to be adapted to the sliding groove 40, when the moving scroll disk 10 is subjected to an axial force, the overturning moment generated in the moving scroll disk 10 can be transmitted to the bracket 20 through the abutting member 50, so as to cancel out with the axial force, enabling the moving scroll disk 10 to maintain a translational state without tilting, and further being able to avoid friction and vibration caused by the tilting of the moving scroll disk 10. Therefore, through the moving scroll disk assembly provided in this embodiment, the technical problem that the moving scroll disk in the prior art is difficult to maintain a translational state during operation can be solved.

[0052] Specifically, "the connecting portion 51 is arranged to be adapted to the installation groove 30" means that along the direction from the bracket 20 to the moving scroll disk 10, the thickness of the connecting portion 51 is adapted to the thickness of the installation groove 30. Specifically, "the abutting portion 52 is arranged to be adapted to the sliding groove 40" means that along the direction from the bracket 20 to the moving scroll disk 10, the thickness of the abutting portion 52 is adapted to the thickness of the sliding groove 40.

[0053] Specifically, for the convenience of the movement of the moving scroll disk 10, along the circumferential direction of the moving scroll disk 10, the width of the sliding groove 40 is greater than the width of the abutting portion 52.

[0054] Specifically, the sliding groove 40 includes a first sliding groove side wall and a second sliding groove side wall arranged oppositely, and the sliding groove 40 further includes a bottom wall, and both the first sliding groove side wall and the second sliding groove side wall are connected to the bottom wall. Specifically, "at least part of the abutting portion 52 is kept in abutment with the groove wall of the sliding groove 40" means that at least part of the abutting portion 52 is kept in abutment with the bottom wall of the sliding groove 40. With such a structural arrangement, when the moving scroll disk 10 moves, under the action of the elastic member 70, at least part of the abutting portion 52 will slide along the surface of the bottom wall in the sliding groove 40, so as to facilitate better maintaining the translational state of the moving scroll disk 10.

[0055] Specifically, the elastic member 70 is located on the side of the connecting portion 51 away from the abutting portion 52 and is connected or abutted to the connecting portion 51. Specifically, one side of the elastic member 70 is connected or abutted to the connecting portion 51, and the other side of the elastic member 70 is connected or abutted to the groove wall of the installation groove 30. With such a structural arrangement, it can facilitate the movement of at least part of the connecting portion 51 in the installation groove 30, enabling the abutting member 50 to quickly generate a supporting reaction force to balance with the axial force received by the moving scroll disk 10.

[0056] Specifically, in order to facilitate ensuring that at least part of the abutting portion 52 can abut against the groove wall of the sliding groove 40, the elastic member 70 is a spring.

[0057] Specifically, a supporting groove 21 is provided on the bracket 20, and at least part of the moving scroll 10 is located in the supporting groove 21; a back pressure chamber 60 is provided at the bottom of the supporting groove 21, and the back pressure chamber 60 is filled with a pressure fluid. Among them, at least part of the back pressure chamber 60 is disposed opposite to at least part of the portion of the moving scroll 10 where the mounting groove 30 is provided. With such a structural arrangement, the axial force received by the moving scroll 10 can be balanced jointly by the back pressure chamber 60 and the abutting member 50, thereby reducing the risk of deformation of the abutting member 50 due to excessive force, and at the same time, it can better ensure the balance of the axial force and ensure the smooth movement of the moving scroll 10. In addition, by making at least part of the back pressure chamber 60 disposed opposite to at least part of the portion of the moving scroll 10 where the mounting groove 30 is provided, the effect of the joint action of the abutting member 50 and the back pressure chamber 60 can be further improved, and the balance efficiency can be accelerated.

[0058] Specifically, the "portion of the moving scroll 10 where the mounting groove 30 is provided" refers to the part of the groove wall of the moving scroll 10 for forming the mounting groove 30.

[0059] Specifically, there are a plurality of mounting grooves 30, and the plurality of mounting grooves 30 are arranged at intervals along the circumference of the moving scroll 10. Among them, the sliding grooves 40, the elastic members 70 and the abutting members 50 are all plural, and the plurality of mounting grooves 30, the plurality of sliding grooves 40, the plurality of abutting members 50 and the plurality of elastic members 70 are all arranged in one-to-one correspondence. With such a structural arrangement, the bearing capacity of the moving scroll 10 for the axial force can be improved through the coordinated arrangement of the plurality of mounting grooves 30, the plurality of sliding grooves 40, the plurality of abutting members 50 and the plurality of elastic members 70, and since the overturning force generated by the axial force in the moving scroll 10 is uneven along the circumference of the moving scroll 10, such an arrangement can better improve the effect of the abutting member 50 offsetting the overturning force.

[0060] Specifically, there are a plurality of mounting grooves 30, and the plurality of mounting grooves 30 are arranged at intervals along the circumference of the moving scroll 10. Among them, the plurality of mounting grooves 30 are evenly spaced along the circumference of the moving scroll 10. With such a structural arrangement, the effect of the abutting member 50 offsetting the overturning force can be better improved, and the situation where the offset effect of the abutting member 50 on a specific angle in the circumferential direction of the moving scroll 10 is poor can be avoided.

[0061] Specifically, as Figure 6 and Figure 7As shown, there are three installation grooves 30, and the three installation grooves 30 are arranged at intervals along the circumference of the moving scroll 10. The corresponding central angle between two adjacent installation grooves 30 is 120°. The sliding grooves 40, elastic members 70 and abutting members 50 are also three in number, and the three installation grooves 30, three sliding grooves 40, three abutting members 50 and three elastic members 70 are arranged in one-to-one correspondence. With such a structural arrangement, the bearing capacity of the moving scroll 10 for axial force can be improved through the cooperation of the three installation grooves 30, three sliding grooves 40, three abutting members 50 and three elastic members 70. And since the overturning force generated inside the moving scroll 10 under the influence of the axial force is uneven along the circumference of the moving scroll 10, such an arrangement can better improve the effect of the abutting member 50 offsetting the overturning force.

[0062] In this embodiment, as Figure 3 and Figure 4 shown, the moving scroll 10 includes a base plate 11 and a tooth portion 12 connected to each other, and the installation groove 30 is arranged on the base plate 11. Among them, d1 = d2, where d1 is the thickness of the installation groove 30 along the thickness direction of the base plate 11, and d2 is the thickness of the sliding groove 40 along the thickness direction of the base plate 11. Specifically, there is a clearance fit between the installation groove 30 and the sliding groove 40 and the abutting member 50. With such a structural arrangement, it can be ensured that when an overturning moment is generated inside the moving scroll 10, the abutting member 50 can, through the abutting and limiting cooperation with the sliding groove 40, ensure the translational state of the moving scroll 10 and avoid the overturning of the moving scroll 10. In the case where d1 and d2 are not the same size, when the dimensional deviation between the two is small, when the moving scroll 10 overturns, the abutting member 50 will tilt at a small angle along with the moving scroll 10, but at this time, the abutting between the abutting member 50 and the sliding groove 40 can still play a limiting role, but the force-bearing surface of the abutting member 50 becomes a point or a line, affecting the service life; when the dimensional deviation between the two is large, when the moving scroll 10 overturns, the abutting member 50 tilts greatly, and at this time, the effect of the abutting member 50 on restricting the overturning is poor.

[0063] Specifically, as Figure 3 , Figure 4 and Figure 5 shown, the moving scroll 10 includes a base plate 11 and a tooth portion 12 connected to each other, and the installation groove 30 is arranged on the base plate 11. Among them, 1 / 2 ≤ d3 / d4 ≤ 2 / 3, where d3 is the thickness of the connecting portion 51 along the thickness direction of the base plate 11, and d4 is the thickness of the base plate 11. Specifically, there is a clearance fit between the installation groove 30 and the abutting member 50. With such a structural arrangement, the structural strength of the abutting member 50 itself can be ensured, and at the same time, it can also be avoided that the part of the groove wall on the base plate 11 for forming the installation groove 30 is too thin, thereby avoiding the force deformation of the moving scroll 10 during the movement process.

[0064] Specifically, in the thickness direction of the substrate 11, the installation groove 30 is arranged in the middle of the substrate 11. With such a structural arrangement, it is possible to avoid the part of the groove wall of the substrate 11 used to form the installation groove 30 from being too thin, thereby ensuring the structural strength of the substrate 11 and preventing the substrate 11 from deforming under force during movement.

[0065] Specifically, as Figure 6 and Figure 7 shown, the length of the abutting member 50 is L, and L ≤ 5D; where D is the depth of the sliding groove 40. With such a structural arrangement, by setting the length of the abutting member 50 and the depth of the sliding groove 40, it is possible to ensure the movement of the abutting member 50 in the sliding groove 40 and avoid affecting the normal operation of the moving scroll 10.

[0066] Specifically, as Figure 6 and Figure 7 shown, the length of the abutting member 50 is L, and L ≥ 2B; where B is the length of the abutting portion 52. With such a structural arrangement, it is possible to prevent the support reaction force generated by the abutting of the abutting member 50 against the bracket 20 from damaging the structures of the abutting member 50 and the substrate 11 of the moving scroll 10, thereby extending the service life of the moving scroll assembly.

[0067] Specifically, as Figure 6 and Figure 7 shown, in order to ensure the normal operation of the moving scroll 10, A ≥ E + C; where A is the width of the sliding groove 40 in the circumferential direction of the moving scroll 10, E is the eccentricity of the moving scroll 10, and C is the width of the connecting portion 51 in the circumferential direction of the moving scroll 10.

[0068] In this embodiment, at least a part of the abutting portion 52 is in point contact or line contact with the groove wall of the sliding groove 40. Specifically, "at least a part of the abutting portion 52 is in point contact or line contact with the groove wall of the sliding groove 40" means that the end of the abutting portion 52 far from the connecting portion 51 is in point contact or line contact with the bottom wall of the sliding groove 40. With such a structural arrangement, it is possible to reduce the friction generated when the abutting portion 52 contacts the bottom wall of the sliding groove 40 as the moving scroll 10 moves, reduce the wear of the abutting member 50 and the bottom wall of the sliding groove 40, and thereby extend the service life of the moving scroll assembly.

[0069] Specifically, in order to further reduce the friction between the abutting portion 52 and the bottom wall of the sliding groove 40, the end of the abutting portion 52 far from the connecting portion 51 is an arc structure.

[0070] Specifically, the abutting member 50 has a strip-shaped structure. With such a structural arrangement, it is more convenient for the power vane 10 to drive the abutting member 50 to move, and the force transmission between the abutting member 50 and the sliding groove 40 is more efficient, making the structure of the power vane assembly simpler and easier to set up. At the same time, such an arrangement facilitates the mold opening manufacturing of the abutting member 50 and the operation of opening the sliding groove 40.

[0071] Specifically, the connecting portion 51 has a cylindrical structure, and the mounting groove 30 is a cylindrical hole groove adapted to the cylindrical structure. One end of the connecting portion 51 away from the abutting portion 52 is a flat surface, so as to facilitate abutting against the elastic member 70.

[0072] Specifically, the connecting portion 51 includes an upper side surface 511 and a lower side surface 512, and the upper side surface 511 and the lower side surface 512 are arranged at intervals along the direction from the bracket 20 to the power vane 10; both the upper side surface 511 and the lower side surface 512 are flat surfaces. With such a structural arrangement, the contact area between the connecting portion 51 and the mounting groove 30 can be increased, thereby reducing the pressure on the contact surface between the connecting portion 51 and the mounting groove 30 and improving the load-bearing capacity of the abutting member 50.

[0073] Specifically, as Figure 8 shown, in the second embodiment of the present invention, there are four mounting grooves 30, and the four mounting grooves 30 are arranged at intervals along the circumference of the power vane 10. The central angle corresponding to two adjacent mounting grooves 30 is 90°. There are also four sliding grooves 40, four elastic members 70, and four abutting members 50, and the four mounting grooves 30, four sliding grooves 40, four abutting members 50, and four elastic members 70 are arranged in one-to-one correspondence. With such a structural arrangement, the cooperation of the four mounting grooves 30, four sliding grooves 40, four abutting members 50, and four elastic members 70 can improve the axial force bearing capacity of the power vane 10, and since the overturning force generated by the influence of the axial force inside the power vane 10 is uneven along the circumference of the power vane 10, such an arrangement can better improve the effect of the abutting member 50 offsetting the overturning force.

[0074] The third embodiment of the present invention provides a pump body assembly, which includes the power vane assembly provided in the first embodiment or the second embodiment, a stationary vane, and a drive shaft. The stationary vane is meshed with the power vane 10 of the power vane assembly. The drive shaft is drivingly connected to the power vane 10.

[0075] By adopting the pump body assembly provided in the third embodiment of the present utility model, through the arrangement of the abutting member 50 and the elastic member 70, at least part of the connecting portion 51 is movably arranged in the mounting groove 30, and in cooperation with the arrangement of the elastic member 70, at least part of the abutting portion 52 connected to the connecting portion 51 is kept in abutment with the groove wall of the sliding groove 40. Through such an arrangement, since the connecting portion 51 is arranged to be adapted to the mounting groove 30 and the abutting portion 52 is arranged to be adapted to the sliding groove 40, when the moving scroll 10 is subjected to an axial force, the overturning moment generated in the moving scroll 10 can be transmitted to the bracket 20 through the abutting member 50, so as to cancel out the axial force, enabling the moving scroll 10 to maintain a translational state without tilting, and further being able to avoid the adverse situation of vibration caused by the mutual friction between the moving scroll 10 and the stationary scroll due to the tilting of the moving scroll 10. Therefore, through the pump body assembly provided in this embodiment, the technical problem that the moving scroll in the prior art is difficult to maintain a translational state during operation can be solved.

[0076] Specifically, the driving end of the driving shaft is used to be inserted into at least part of the moving scroll 10, and the driving end of the driving shaft is in clearance fit with at least part of the moving scroll 10. Among them, the connecting portion 51 of the moving scroll assembly is in clearance fit with the mounting groove 30 of the moving scroll assembly, and the clearance between the connecting portion 51 and the mounting groove 30 is smaller than the clearance between the driving shaft and at least part of the moving scroll 10. With such a structural arrangement, it is possible to prevent the small fluctuations between the connecting portion 51 and the mounting groove 30 from being directly transmitted to the driving shaft, so as to keep the oil film between the driving shaft and the moving scroll 10 stable during operation, and further facilitate maintaining the normal operation of the pump body assembly.

[0077] Specifically, in order to better ensure the normal rotation of the moving scroll 10, the pump body assembly further includes a cross slip ring 80. The cross slip ring 80 is arranged between the moving scroll 10 and the bracket 20, and the cross slip ring 80 is used to prevent the self-rotation of the moving scroll 10.

[0078] Specifically, the tooth portion of the moving scroll 10 and the tooth portion of the stationary scroll are engaged with each other to form a compression chamber. When the compression chamber compresses the refrigerant, an axial force will be generated, and the axial force will cause a tendency for the moving scroll 10 and the stationary scroll to be axially separated. In this application, the arrangements of the abutting member 50 and the back pressure chamber 60 are both used to balance the axial force generated when the compression chamber compresses the refrigerant.

[0079] Embodiment 4 of the present utility model provides a compressor, which includes the pump body assembly provided in Embodiment 3. By using the compressor provided in Embodiment 4 of the present utility model, through the arrangement of the abutting member 50 and the elastic member 70, at least part of the connecting portion 51 is movably arranged in the mounting groove 30, and in cooperation with the arrangement of the elastic member 70, at least part of the abutting portion 52 connected to the connecting portion 51 remains in abutment with the groove wall of the sliding groove 40. Through such an arrangement, since the connecting portion 51 is arranged to be adapted to the mounting groove 30 and the abutting portion 52 is arranged to be adapted to the sliding groove 40, when the moving scroll 10 is subjected to an axial force, the overturning moment generated in the moving scroll 10 can be transmitted to the bracket 20 through the abutting member 50, so as to cancel out the axial force, so that the moving scroll 10 can maintain a translational state without tilting, and further, the bad condition that the moving scroll 10 and the stationary scroll rub against each other to generate vibration due to the tilting of the moving scroll 10 can be avoided. Therefore, through the compressor provided in this embodiment, the technical problem that the moving scroll in the prior art is difficult to maintain a translational state during operation can be solved.

[0080] Specifically, the compressor provided in Embodiment 4 of the present utility model is a scroll compressor.

[0081] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: balancing the axial gas force generated in the compression chamber, preventing the moving scroll from overturning, reducing the friction of the teeth of the moving scroll, and preventing leakage between the moving and stationary scrolls. At the same time, the axial gas force received by the moving disk is transmitted to the bracket structure through the connecting structure and will not be transmitted to the shafting, ensuring that the oil film between the shafting and the moving disk bearing remains stable during operation and reducing the noise and vibration of the compressor.

Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the description. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0084] In the description of the present application, it should be understood that the orientation or positional relationships indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc. are usually based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present application and simplifying the description. Without contrary description, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present application; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0085] For ease of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship of a device or feature shown in the drawings with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation described in the drawings for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0086] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without otherwise stating, the above words have no special meanings. Therefore, it cannot be understood as a limitation on the protection scope of the present application.
