Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to a compressor, an air conditioning system, and a vehicle. Background Technology

[0002] Currently, the compressor is a core component of automotive refrigeration equipment. The compressor generates vibration and noise during operation, thus causing noise and vibration problems in the vehicle. Related technologies include... Figure 1 As shown, the compressor includes a rotating shaft 1' and a scroll compressor section 2' connected to the rotating shaft 1', as follows: Figure 2 and Figure 3 As shown, the bracket 3' is equipped with a bearing housing 30' and an anti-rotation component 32'. The rotating shaft 1' is mounted on the bearing housing 30', and the anti-rotation component 32' prevents the rotating parts of the scroll compressor section 2' from rotating. When the compressor operates at high speed, the centrifugal force on its rotating shaft components will increase significantly. Under this force, the bracket 3' used to fix the bearing will undergo relatively obvious local deformation, which will cause the compressor's noise and vibration to deteriorate. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, a first aspect of the present invention provides a compressor.

[0005] A second aspect of the present invention also provides an air conditioning system.

[0006] A third aspect of the invention also provides a vehicle.

[0007] In view of this, a first aspect of the present invention provides a compressor comprising: a rotating shaft; a motor unit connected to the rotating shaft; a scroll compressor unit connected to the rotating shaft, the scroll compressor unit including a rotating member; a bracket disposed between the motor unit and the scroll compressor unit, the bracket including: a bearing housing on which the rotating shaft is mounted; a flat portion extending from an end face of the bearing housing toward the scroll compressor unit along the axial direction of the rotating shaft; an anti-rotation member disposed on the flat portion and cooperating with the rotating member; and a connecting portion disposed on the outer side wall of the flat portion along the radial direction of the rotating shaft, the connecting portion being located between the end face of the connecting portion away from the rotating member and the end face of the flat portion near the rotating member along the axial direction of the rotating shaft.

[0008] The compressor provided by this invention includes a rotating shaft, a motor unit, a scroll compressor unit, and a support. Both the motor unit and the scroll compressor unit are connected to the rotating shaft. The motor unit drives the rotating shaft to rotate, which in turn drives the scroll compressor unit to move, thereby compressing the refrigerant. The support is disposed between the motor unit and the scroll compressor unit. The support includes a bearing housing, a flat portion, an anti-rotation component, and a connecting portion. The rotating shaft is mounted on the bearing housing, and the anti-rotation component is disposed on the flat portion, which extends from the end face of the bearing housing towards the scroll compressor unit. The anti-rotation component cooperates with the rotating component of the scroll compressor unit to prevent the rotating component from rotating during circumferential rotation, ensuring the reliability of the scroll compressor unit's refrigerant compression. During normal compressor operation, the motor drives the rotating shaft to rotate, which in turn drives the scroll compressor section. During this motion, the rotating shaft, due to its unbalanced structure, generates centrifugal force. Simultaneously, the scroll compressor section, during its rotation, is also subjected to centrifugal force and the gas generated by compressing the refrigerant. These forces are transmitted to the anti-rotation component that cooperates with the rotating component. Therefore, the forces generated during the rotation of the shaft and scroll compressor section are transferred to the support, causing the support to bear the forces from the shaft and rotating component. In the technical solution proposed in this application, a connecting portion is provided on the outer wall of the flat section. Along the axial direction of the rotating shaft, the end face of the connecting portion near the rotating component is located between the end face of the connecting portion away from the rotating component and the end face of the flat section near the rotating component. This places the two forces-bearing parts of the support on both sides of the connecting portion, thereby changing the overall stress distribution of the support and improving the compressor's operating noise and vibration.

[0009] In practical applications, at least a portion of the connecting part is recessed towards the motor part, thereby balancing the forces exerted on the support by the rotating shaft and the vortex compression part, and avoiding vibration and noise caused by support deformation.

[0010] Furthermore, the compressor includes a housing, which includes a first housing and a second housing. A rotating shaft and a motor are disposed within the first housing, a scroll compressor is disposed within the second housing, and a bracket is disposed between the first housing and the second housing. The bracket is connected to the first housing and the second housing via a connecting part.

[0011] It is understandable that the flat part extends from the end of the bearing housing near the rotating part towards the vortex compression part. Therefore, the force from the vortex compression part borne by the flat part and the force from the rotating shaft borne by the bearing housing are located on both sides of the bracket. Therefore, by recessing the connecting part from the end of the flat part near the rotating part towards the motor part, the external forces borne by the bearing housing and the flat part can be balanced, thereby improving the deformation of the bracket caused by the imbalance of forces, and thus reducing the vibration and noise caused by the deformation of the bracket.

[0012] The compressor provided by the present invention may also have the following additional technical features:

[0013] In some possible designs, the compressor also includes: a bearing, located in a bearing housing, with the rotating shaft connected to the bearing housing via the bearing; in a cross-section of the plane containing the axis of the rotating shaft, along the axial direction of the rotating shaft, the distance between the geometric center of the cross-section of the connecting part and the center of the axial length of the portion of the anti-rotation component protruding from the flat part is L1, and the distance between the geometric center of the cross-section of the connecting part and the center of the axial length of the bearing is L2, the ratio between L1 and L2 is greater than or equal to 0.75 and less than or equal to 1.5.

[0014] In this design, the compressor also includes bearings, which are mounted on bearing housings. The rotating shaft is mounted on the bearings to enable the shaft to rotate and reduce friction between the shaft and the bearing housing.

[0015] During operation, the rotating component of the vortex compressor contacts the support through the anti-rotation component. Therefore, the centrifugal force generated when the rotating component rotates in a circumferential direction is transmitted to the support through the anti-rotation component. The centrifugal force generated when the shaft rotates is transmitted to the support through the bearing. By placing the end face of the flat part facing the rotating component between the end face of the rotating component and the end face of the connecting part facing the rotating component, the connecting part can balance the force transmitted to the support by the bearing and the anti-rotation component, thereby reducing the deformation of the support and avoiding vibration and noise problems caused by the deformation of the support.

[0016] It is understandable that the vortex compression section is a vortex-type compression structure. One part of the anti-rotation component extends into the flat section, and the other part protrudes from the end face of the flat section facing the rotating component, which is used to limit the rotation of the rotating component of the vortex compression section when it rotates with the shaft.

[0017] Furthermore, the axis of the rotating shaft coincides with the axis of the bearing.

[0018] The connecting part is located between the end face of the flat part near the rotating part and the end face of the connecting part away from the rotating part. This allows the connecting part to balance the forces from the bearing and the anti-rotation component. However, if the axial dimension of the connecting part is too small, it will reduce the balancing effect of the forces from the bearing and the anti-rotation component and reduce the strength of the bracket. If the axial dimension of the connecting part is too large, it will reduce the balancing effect of the forces from the anti-rotation component and the bearing. Therefore, in the cross-section of the plane where the axis of the rotating shaft is located, along the axial direction of the rotating shaft, the ratio of L1 to L2 of the connecting part is set between 0.75 and 1.5. This ensures both the balancing effect of the forces from the bearing and the anti-rotation component and the strength of the bracket, thereby reducing the degree of bracket deformation and improving the operating noise and vibration of the compressor caused by bracket deformation.

[0019] Wherein, L1 is the length between the geometric center of the connecting section and the center of the axial length of the anti-rotation component protruding from the flat section in the cross section of the plane where the axis of the rotating shaft is located, and L2 is the length between the geometric center of the connecting section and the center of the axial length of the bearing in the cross section of the plane where the axis of the rotating shaft is located.

[0020] It is understandable that during compressor operation, the geometric center of the cross-section of the connecting part is the force center of the connecting part, the center of the axial length of the portion of the anti-rotation component protruding from the flat part is the center of the length of the portion of the anti-rotation component protruding from the flat part along the axial direction of the rotating shaft, and the center of the axial length of the bearing is the center of the length of the bearing along the axial direction of the rotating shaft.

[0021] In some possible designs, the bracket may also include a mounting portion located on the outer wall of the connector along the radial direction of the pivot.

[0022] In this design, the bracket also includes a mounting part, which is located on the outer side wall of the connecting part along the radial direction of the rotating shaft. This mounting part is used to install the bracket on the compressor housing, thereby improving the reliability of the connection between the bracket and the housing.

[0023] In some possible designs, along the axial direction of the shaft, the end face of the mounting part near the rotating part and the end face of the connecting part near the rotating part are on the same plane.

[0024] In this design, along the axial direction of the rotating shaft, the end face of the mounting part near the rotating part and the end face of the connecting part near the rotating part are on the same plane. The mounting part can also balance the forces from the bearing and the anti-rotation part, thereby reducing the degree of deformation of the bracket and avoiding abnormal compressor vibration or excessive noise caused by bracket deformation.

[0025] In some possible designs, along the axial direction of the shaft, the end face of the mounting part near the rotating component and the end face of the connecting part near the rotating component are on different planes.

[0026] In this design, along the axial direction of the shaft, the end face of the mounting part near the rotating component and the end face of the connecting part near the rotating component are not on the same plane. In one design, along the axial direction of the shaft, the end face of the mounting part near the rotating component protrudes beyond the end face of the connecting part near the rotating component, increasing the thickness of the mounting part and thus improving the connection strength between the bracket and the compressor housing, and enhancing the compressor's sealing performance. In another design, along the axial direction of the shaft, the end face of the connecting part near the rotating component protrudes beyond the end face of the mounting part near the rotating component, so that the mounting part can also balance the forces from the bearing and the anti-rotation component, reducing the degree of deformation of the bracket.

[0027] In some possible designs, the end face of the mounting part facing the motor part and the end face of the connecting part facing the motor part are on the same plane.

[0028] In this design, the end face of the mounting part facing the motor part and the end face of the connecting part facing the motor part are on the same plane, which facilitates the manufacture of the bracket, reduces production costs, and enables the mounting part to balance the forces from the bearing and the anti-rotation component, thereby reducing the degree of deformation of the bracket.

[0029] In some possible designs, the end face of the mounting part facing the motor part and the end face of the connecting part facing the motor part are on different planes.

[0030] In this design, the end face of the mounting part facing the motor and the end face of the connecting part facing the motor are not on the same plane. In one design, along the axial direction of the shaft, the end face of the mounting part facing the motor protrudes beyond the end face of the connecting part facing the motor, increasing the thickness of the mounting part and thus improving the strength of the bracket and the reliability of the connection between the bracket and the compressor housing. In another design, along the axial direction of the shaft, the end face of the connecting part facing the motor protrudes beyond the mounting part. Therefore, the mounting part can also balance the forces from the bearings and anti-rotation components, reducing the deformation of the bracket and lowering production costs.

[0031] In some possible designs, the two ends of the mounting portion protrude from the connecting portion along the axial direction of the rotating shaft.

[0032] In this design, both ends protrude from the connection part along the axial direction, which can not only balance the stress on the bracket, but also improve the connection strength between the bracket and the compressor housing, thereby improving the operating noise and vibration of the compressor.

[0033] In some possible designs, along the axial direction of the shaft, the end face of the mounting part near the motor part is flush with the connecting part, and the end face of the mounting part near the rotating part protrudes from the connecting part.

[0034] In this design, the wall of the mounting part near the motor part is flush with the connecting part, and the wall of the mounting part near the rotating part protrudes from the connecting part, thereby increasing the thickness of the mounting part and ensuring the connection strength between the mounting part and the compressor housing.

[0035] In some possible designs, along the axial direction of the shaft, the end face of the mounting portion near the rotating part and the end face of the flat portion near the rotating part are located on different planes.

[0036] In this design, along the axial direction of the shaft, the end face of the mounting portion near the rotating component and the end face of the flat portion near the rotating component are not on the same plane. In one design, along the axial direction of the shaft, the end face of the mounting portion near the rotating component protrudes beyond the end face of the flat portion near the rotating component, increasing the thickness of the mounting portion and thus improving the reliability of the connection between the bracket and the compressor housing. In another design, along the axial direction of the shaft, the end face of the flat portion near the rotating component protrudes beyond the end face of the mounting portion near the rotating component, thereby enabling the mounting portion to balance the forces from the bearing and the anti-rotation component, reducing the deformation of the bracket and also reducing production costs.

[0037] In some possible designs, along the axial direction of the shaft, the end face of the mounting portion near the rotating part and the end face of the flat portion near the rotating part are located on the same plane.

[0038] In this design, along the axial direction of the rotating shaft, the end face of the mounting part near the rotating part and the end face of the flat part near the rotating part are located on the same plane, which can improve the connection strength between the mounting part and the compressor housing, and also facilitate the production and manufacturing of the bracket.

[0039] In some possible designs, the connecting part has a cutout section.

[0040] In this design, the connecting part has a hollow section, which allows the spaces on both sides of the connecting part to be connected so that airflow can pass through.

[0041] In practical applications, the hollowed-out part includes through holes, and further, the shape of the through holes is arc-shaped or strip-shaped.

[0042] Furthermore, there are multiple hollowed-out sections, which are distributed circumferentially along the axis of rotation on the connecting section.

[0043] In some possible designs, in any two sections of the plane containing the axis of the pivot, the sections of the connecting part without the cutout have the same cross-sectional shape.

[0044] In this design, in any two sections of the plane containing the axis of the rotating shaft, the sections of the connecting part without the hollowed-out part have the same cross-sectional shape, that is, the connecting part is a uniform cross-sectional structure, thereby ensuring the balance effect of the connecting part on the forces brought by the bearing and the anti-rotation component.

[0045] In some possible designs, the part of the connecting section without a cutout is a variable cross-section structure.

[0046] In this design, the portion of the connecting part without the perforation is a variable cross-section structure, which facilitates the manufacturing of the connecting part. This reduces material usage while increasing the strength of the support frame and decreasing its deformation, thereby improving the vibration and noise issues of the compressor.

[0047] In some possible designs, the cross-sectional shape of the connecting part in the plane containing the axis of the rotating shaft includes any one of square, triangular, or rhomboid shapes.

[0048] In this design, the shape of the connecting part in the cross-section of the plane containing the axis of the rotating shaft can be any of a square, triangle, or rhombus. This facilitates the manufacturing of the connecting part, reduces material usage, increases the strength of the support, reduces the degree of deformation of the support, and thus improves the vibration and noise problems of the compressor. In specific applications, the cross-section of the portion of the connecting part without the cutout in the cross-section of the plane containing the axis of the rotating shaft is formed by any of a square, triangle, rhombus, or quadrilateral other than square and rhombus. Of course, the cross-sectional shape of the portion of the connecting part without the cutout can also be other polygons.

[0049] In some possible designs, the end face of the connecting part near the rotating part is provided with reinforcing ribs.

[0050] In this design, a reinforcing rib is provided on the end face of the connecting part near the rotating part, which improves the strength of the connecting part and thus prevents the bracket from deforming due to the force from the bearing and the anti-rotation part during the operation of the compressor.

[0051] In practical applications, in the cross-section of the plane passing through the axis of the rotating shaft, the reinforcing rib is triangular. One side of the triangular reinforcing rib fits into the connecting part, and the other side fits into the mounting part, which improves the strength of the connecting part.

[0052] In some possible designs, the anti-rotation component includes a pin.

[0053] In this design, the anti-rotation component includes a pin, part of which is inserted into the end face of the flat section, while the other part protrudes from the flat section, to prevent the rotating component of the vortex compression section from rotating. The pin design reduces production costs.

[0054] In some possible designs, there are multiple anti-rotation components.

[0055] In this design, there are multiple anti-rotation components. The multiple anti-rotation components improve the restriction effect on the rotating parts of the scroll compressor, ensuring the compression effect of the scroll compressor on the refrigerant.

[0056] Furthermore, multiple anti-rotation components are distributed circumferentially along the axis of rotation.

[0057] Understandably, the minimum outer perimeter of the flat section must include the entire outer diameter of the anti-rotation component, so that the anti-rotation component is entirely within the area of ​​the flat section.

[0058] In some possible designs, the rotating component includes a moving scroll.

[0059] In this design, the rotating component includes a moving scroll, which compresses the refrigerant through its rotational motion. An anti-rotation component prevents the moving scroll from rotating during its rotation, ensuring reliable refrigerant compression.

[0060] Furthermore, the vortex compression section also includes a stationary vortex disk, and the moving vortex disk meshes with the stationary vortex disk to form a compression cavity.

[0061] Understandably, the rotating scroll of the scroll compressor is subjected to centrifugal force and the gas generated during refrigerant compression during its rotational motion. This force is transferred to the support frame via an anti-rotation component. Therefore, the support frame bears the forces from both the bearings on the rotating shaft and the anti-rotation component. When the compressor operates at high speeds, the centrifugal force it experiences increases significantly. Consequently, the support frame undergoes relatively noticeable localized deformation under these forces, leading to increased noise and vibration in the compressor. By defining the positional relationship and dimensions of the connecting and flat sections, the overall stress on the support frame can be improved, thereby reducing vibration and noise in the compressor at high speeds.

[0062] In some possible designs, the compressor may also include: a first housing, in which the motor is located; a second housing, in which the scroll compressor is located; a bracket sandwiched between the first and second housings; and a mounting portion of the bracket connected to the first and second housings, wherein the pressure borne by the first housing is less than the pressure borne by the second housing.

[0063] In this design, the compressor also includes a first housing and a second housing. The motor unit is located inside the first housing, the scroll compressor unit is located inside the second housing, and a bracket is located between the first and second housings. The bracket is connected to the first and second housings via a mounting part. This fixes the bracket, reduces its deformation, and thus reduces vibration or noise caused by deformation. The first housing withstands less pressure than the second housing; that is, the first housing is a low-pressure housing, and the second housing is a high-pressure housing. When the compressor is operating normally, gaseous refrigerant enters the low-pressure housing cavity through the compressor's suction port and flows through the motor unit and bracket into the scroll compressor unit. The high-pressure gas formed after the refrigerant passes through the scroll compressor unit is discharged into the compression chamber enclosed by the high-pressure housing and leaves the compressor through the discharge port.

[0064] According to a second aspect of the present invention, an air conditioning system is also provided, comprising: a compressor as described in any of the above-described technical solutions.

[0065] The air conditioning system provided in the second aspect of the present invention, because it includes the compressor proposed in any of the above-mentioned technical solutions, has all the beneficial effects of the compressor.

[0066] Specifically, the air conditioning system also includes a condenser and a heat exchanger. The compressor, condenser and heat exchanger are connected in series to form a heat exchange flow path, and the refrigerant flows in the heat exchange flow path to achieve the cooling or heating effect.

[0067] According to a third aspect of the invention, a vehicle is also provided, comprising: a compressor as described in any of the technical solutions of the first aspect above, or an air conditioning system as described in the second aspect.

[0068] The vehicle provided by the third aspect of the present invention, having all the beneficial effects of the compressor or the air conditioning system as proposed in any of the above-mentioned technical solutions, or as proposed in the second aspect.

[0088] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0089] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0090] The following reference Figures 4 to 13 A compressor, an air conditioning system, and a vehicle are described according to some embodiments of the present invention.

[0091] like Figure 4 , Figure 5 and Figure 6 As shown, according to a first embodiment of the present invention, the present invention provides a compressor comprising: a rotating shaft 1, a motor unit 2, a scroll compressor unit 3, and a support 4.

[0092] Specifically, the motor unit 2 is connected to the rotating shaft 1. The scroll compressor unit 3 is connected to the rotating shaft 1 and includes a rotating member 30. A bracket 4 is disposed between the motor unit 2 and the scroll compressor unit 3. The bracket 4 includes a bearing housing 40, a flat portion 41, an anti-rotation member 42, and a connecting portion 43. The rotating shaft 1 is mounted on the bearing housing 40. Along the axial direction of the rotating shaft 1, the flat portion 41 extends from the end face of the bearing housing 40 to the scroll compressor unit 3. The anti-rotation member 42 is disposed on the flat portion 41 and cooperates with the rotating member 30 to prevent the rotating member 30 from rotating during circumferential rotation. Along the radial direction of the rotating shaft 1, the connecting portion 43 is disposed on the outer side wall of the flat portion 41. Along the axial direction of the rotating shaft 1, the end face of the connecting portion 43 near the rotating member 30 is located between the end face of the connecting portion 43 away from the rotating member 30 and the end face of the flat portion 41 near the rotating member 30.

[0093] The compressor provided by this invention includes a rotating shaft 1, a motor unit 2, a scroll compressor unit 3, and a support 4. Both the motor unit 2 and the scroll compressor unit 3 are connected to the rotating shaft 1. The motor unit 2 drives the rotating shaft 1 to rotate, thereby driving the scroll compressor unit 3 to move and compress the refrigerant. The support 4 is disposed between the motor unit 2 and the scroll compressor unit 3. The support 4 includes a bearing housing 40, a flat portion 41, an anti-rotation component 42, and a connecting portion 43. The rotating shaft 1 is mounted on the bearing housing 40. The anti-rotation component 42 is disposed on the flat portion 41, and the flat portion 41 extends from the end face of the bearing housing 40 towards the scroll compressor unit 3. The anti-rotation component 42 cooperates with the rotating component 30 of the scroll compressor unit 3 to prevent the rotating component 30 from rotating during circumferential rotation, ensuring the reliability of the refrigerant compression by the scroll compressor unit 3. During normal operation of the compressor, the motor 2 drives the rotating shaft 1 to rotate, and the rotating shaft 1 drives the scroll compressor 3 to move. During the above-mentioned movement, due to its own unbalanced structure, the rotating shaft 1 generates centrifugal force during rotation. At the same time, during the movement of the scroll compressor 3, its rotating component 30 is also subjected to centrifugal force and the gas generated by compressing the refrigerant. These forces are also transmitted to the anti-rotation component 42 that cooperates with the rotating component 30. Therefore, the forces generated during the movement of the rotating shaft 1 and the scroll compressor 3 are transferred to the support 4, so that the support 4 bears the forces from the rotating shaft 1 and the rotating component 30. In the embodiment proposed in this application, a connecting portion 43 is provided on the outer wall of the flat portion 41, and along the axial direction of the rotating shaft 1, the end face of the connecting portion 43 near the rotating component 30 is located between the end face of the connecting portion 43 away from the rotating component 30 and the end face of the flat portion 41 near the rotating component 30. This makes the two parts of the support 4 that bear the force located on both sides of the connecting portion 43, thereby changing the overall force situation of the support 4 and improving the operating noise and vibration of the compressor.

[0094] In practical applications, at least a portion of the connecting part 43 is recessed towards the motor part 2, thereby the connecting part 43 can balance the forces exerted on the bracket 4 by the rotating shaft 1 and the vortex compression part 3, and avoid vibration and noise caused by deformation of the bracket 4.

[0095] Furthermore, the compressor includes a first housing 6 and a second housing 7, a rotating shaft 1 and a motor 2 are disposed in the first housing 6, a scroll compressor 3 is disposed in the second housing 7, and a bracket 4 is disposed between the first housing 6 and the second housing 7. The bracket 4 is connected to the first housing 6 and the second housing 7 through a connecting part 43.

[0096] It is understandable that the flat portion 41 extends from the end of the bearing housing 40 near the rotating member 30 toward the vortex compression portion 3. Therefore, the force from the vortex compression portion 3 borne by the flat portion 41 and the force from the rotating shaft 1 borne by the bearing housing 40 are located on both sides of the bracket 4. Therefore, by recessing the connecting portion 43 from the end of the flat portion 41 near the rotating member 30 toward the motor portion 2, the external forces borne by the bearing housing 40 and the flat portion 41 can be balanced, thereby improving the deformation of the bracket 4 caused by the unbalanced force, and thus reducing the vibration and noise caused by the deformation of the bracket 4.

[0097] like Figure 6 , Figure 8 , Figure 10 and Figure 12 As shown, according to the second embodiment of the present invention, based on the first embodiment described above, the compressor further includes, in some possible designs, a bearing 5, which is disposed within a bearing housing 40, and the rotating shaft 1 is connected to the bearing housing 40 via the bearing 5.

[0098] In this design, the compressor also includes a bearing 5, which is mounted on a bearing housing 40. The rotating shaft 1 is mounted on the bearing 5 to enable the rotation of the rotating shaft 1 and reduce the friction between the rotating shaft 1 and the bearing housing 40.

[0099] During operation of the vortex compression unit 3, the rotating part 30 of the vortex compression unit 3 contacts the support 4 through the anti-rotation part 42. Therefore, the centrifugal force generated when the rotating part 30 rotates in the circumferential direction is transmitted to the support 4 through the anti-rotation part 42. The centrifugal force generated when the rotating shaft 1 rotates is transmitted to the support 4 through the bearing 5. By setting the end face of the flat part 41 facing the rotating part 30 between the end face of the rotating part 30 and the end face of the connecting part 43 facing the rotating part 30, the connecting part 43 can balance the force transmitted to the support 4 by the bearing 5 and the anti-rotation part 42, thereby reducing the deformation of the support 4 and avoiding vibration and noise problems caused by the deformation of the support 4.

[0100] It is understandable that the vortex compression section 3 is a vortex compression structure. Part of the anti-rotation member 42 extends into the flat section 41, and another part protrudes from the end face of the flat section 41 facing the rotating member 30, which is used to limit the rotation of the rotating member 30 of the vortex compression section 3 when it rotates with the rotating shaft 1.

[0101] Furthermore, the axis of the rotating shaft 1 coincides with the axis of the bearing 5.

[0102] In the cross section of the plane containing the axis of the rotating shaft 1, along the axial direction of the rotating shaft 1, the distance between the geometric center of the cross section of the connecting part 43 and the center of the axial length of the portion of the anti-rotation member 42 protruding from the flat part 41 is L1, and the distance between the geometric center of the cross section of the connecting part 43 and the center of the axial length of the bearing 5 is L2. The ratio between L1 and L2 is greater than or equal to 0.75 and less than or equal to 1.5.

[0103] In this design, the connecting part 43 is located near the end face of the rotating member 30, between the end face of the flat part 41 near the rotating member 30 and the end face of the connecting part 43 away from the rotating member 30. This allows the connecting part 43 to balance the forces from the bearing 5 and the anti-rotation member 42. However, if the axial dimension of the connecting part 43 is too small, it will reduce the balancing effect on the forces from the bearing 5 and the anti-rotation member 42 and reduce the strength of the bracket 4. If the axial dimension of the connecting part 43 is too large, it will reduce the balancing effect on the forces from the anti-rotation member 42 and the bearing 5. Therefore, in the cross-section of the plane where the axis of the rotating shaft 1 is located, along the axial direction of the rotating shaft 1, the connecting part 43 sets the ratio of L1 to L2 between 0.75 and 1.5, that is, 0.75≤L1 / L2≤1.5. This ensures both the balancing effect on the forces from the bearing 5 and the anti-rotation member 42 and the strength of the bracket 4, thereby reducing the deformation of the bracket 4 and improving the operating noise and vibration of the compressor caused by the deformation of the bracket 4.

[0104] Wherein, L1 is the length between the geometric center of the cross section of the connecting part 43 and the center of the axial length of the portion of the anti-rotation member 42 protruding from the flat part 41 in the cross section of the plane where the axis of the rotating shaft 1 is located, and L2 is the length between the geometric center of the cross section of the connecting part 43 and the center of the axial length of the bearing 5 in the cross section of the plane where the axis of the rotating shaft 1 is located.

[0105] In practical applications, the ratio of L1 to L2 can be any value among 0.75, 0.8, 0.85, 0.9, 0.95, 1, 1.05, 1.1, 1.15, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45, and 1.5.

[0106] like Figure 6 , Figure 8 , Figure 10 and Figure 12As shown, according to a third embodiment of the present invention, based on any of the above embodiments, the bracket 4 further includes a mounting portion 44, which is disposed on the outer side wall of the connecting portion 43 along the radial direction of the rotating shaft 1.

[0107] In this design, the bracket 4 also includes a mounting part 44. Along the radial direction of the rotating shaft 1, the mounting part 44 is disposed on the outer side wall of the connecting part 43 for mounting the bracket 4 on the compressor housing 6, thereby improving the reliability of the connection between the bracket 4 and the housing 6.

[0108] In practical applications, the mounting part 44 is arranged in a ring on the outer side wall of the connecting part 43. While realizing the connection between the housing 6 and the bracket 4, it can also ensure the sealing effect of the compressor, thereby ensuring the compression effect of the compressor on the refrigerant.

[0109] like Figure 7 and Figure 8 As shown, according to the fourth embodiment of the present invention, based on the above embodiment three, further: along the axial direction of the rotating shaft 1, the end face of the mounting part 44 near the rotating member 30 and the end face of the connecting part 43 near the rotating member 30 are on the same plane.

[0110] In this design, along the axial direction of the rotating shaft 1, the end face of the mounting part 44 near the rotating member 30 and the end face of the connecting part 43 near the rotating member 30 are on the same plane. The mounting part 44 can also balance the forces from the bearing 5 and the anti-rotation member 42, thereby reducing the degree of deformation of the bracket 4 and avoiding abnormal compressor vibration or excessive noise caused by the deformation of the bracket 4.

[0111] like Figure 9 and Figure 10 As shown, according to the fifth embodiment of the present invention, based on the above embodiment three, further: along the axial direction of the rotating shaft 1, the end face of the mounting part 44 near the rotating member 30 and the end face of the connecting part 43 near the rotating member 30 are on different planes.

[0112] In this design, along the axial direction of the shaft 1, the end face of the mounting part 44 near the rotating member 30 and the end face of the connecting part 43 near the rotating member 30 are not on the same plane. In one design, along the axial direction of the shaft 1, the end face of the mounting part 44 near the rotating member 30 protrudes beyond the end face of the connecting part 43 near the rotating member 30, thereby increasing the thickness of the mounting part 44, thus improving the connection strength between the bracket 4 and the compressor housing 6 and enhancing the sealing performance of the compressor. In another design, along the axial direction of the shaft 1, the end face of the connecting part 43 near the rotating member 30 protrudes beyond the end face of the mounting part 44 near the rotating member 30, so that the mounting part 44 can also balance the forces from the bearing 5 and the anti-rotation member 42, reducing the degree of deformation of the bracket 4.

[0113] like Figure 7 and Figure 8 As shown, according to the sixth embodiment of the present invention, based on the above-described embodiment three, the end face of the mounting portion 44 facing the motor portion 2 and the end face of the connecting portion 43 facing the motor portion 2 are on the same plane.

[0114] In this design, the end face of the mounting part 44 facing the motor part 2 and the end face of the connecting part 43 facing the motor part 2 are on the same plane, which facilitates the manufacturing of the bracket 4, reduces production costs, and enables the mounting part 44 to balance the forces from the bearing 5 and the anti-rotation component 42, thereby reducing the degree of deformation of the bracket 4.

[0115] like Figure 9 and Figure 10 As shown, according to the seventh embodiment of the present invention, based on the above-described embodiment three, the end face of the mounting part 44 facing the motor part 2 and the end face of the connecting part 43 facing the motor part 2 are on different planes.

[0116] In this design, the end face of the mounting portion 44 facing the motor portion 2 and the end face of the connecting portion 43 facing the motor portion 2 are not on the same plane. In one design, along the axial direction of the rotating shaft 1, the end face of the mounting portion 44 facing the motor portion 2 protrudes beyond the end face of the connecting portion 43 facing the motor portion 2, increasing the thickness of the mounting portion 44, thereby improving the strength of the bracket 4 and enhancing the reliability of the connection between the bracket 4 and the compressor housing 6. In another design, along the axial direction of the rotating shaft 1, the end face of the connecting portion 43 facing the motor portion 2 protrudes beyond the mounting portion 44. Therefore, the mounting portion 44 can also balance the forces from the bearing 5 and the anti-rotation component 42, reducing the deformation of the bracket 4 and also lowering production costs.

[0117] According to the eighth embodiment of the present invention, based on the above-described embodiment three, the mounting portion 44 protrudes from the connecting portion 43 at both ends along the axial direction of the rotating shaft 1.

[0118] In this design, both ends along the axial direction protrude from the connecting part 43, which can balance the force on the bracket 4 and improve the connection strength between the bracket 4 and the compressor housing, thereby improving the operating noise and vibration of the compressor.

[0119] According to the ninth embodiment of the present invention, based on the above embodiment three, further: along the axial direction of the rotating shaft 1, the end face of the mounting part 44 near the motor part 2 is flush with the connecting part 43, and the end face of the mounting part 44 near the rotating member 30 protrudes from the connecting part 43.

[0120] In this design, the wall surface of the mounting part 44 near the motor part 2 is flush with the connecting part 43, and the wall surface of the mounting part 44 near the rotating part 30 protrudes from the connecting part 43, thereby increasing the thickness of the mounting part 44 and ensuring the connection strength between the mounting part 44 and the compressor housing.

[0121] like Figures 7 to 10 As shown, according to the tenth embodiment of the present invention, based on the above embodiment three, further: along the axial direction of the rotating shaft 1, the end face of the mounting portion 44 near the rotating member 30 and the end face of the flat portion 41 near the rotating member 30 are located on different planes.

[0122] In this design, along the axial direction of the shaft 1, the end face of the mounting portion 44 near the rotating member 30 and the end face of the flat portion 41 near the rotating member 30 are not on the same plane. In one design, along the axial direction of the shaft 1, the end face of the mounting portion 44 near the rotating member 30 protrudes beyond the end face of the flat portion 41 near the rotating member 30, increasing the thickness of the mounting portion 44 and thus improving the reliability of the connection between the bracket 4 and the compressor housing 6. In another design, along the axial direction of the shaft 1, the end of the flat portion 41 near the rotating member 30 protrudes beyond the end face of the mounting portion 44 near the rotating member 30, thereby enabling the mounting portion 44 to balance the forces from the bearing 5 and the anti-rotation member 42, reducing the deformation of the bracket 4 and also reducing production costs.

[0123] like Figure 5 and Figure 6 As shown, according to the eleventh embodiment of the present invention, based on the above embodiment three, further: along the axial direction of the rotating shaft 1, the end face of the mounting portion 44 near the rotating member 30 and the end face of the flat portion 41 near the rotating member 30 are located on the same plane.

[0124] In this design, along the axial direction of the rotating shaft 1, the end face of the mounting part 44 near the rotating member 30 and the end face of the flat part 41 near the rotating member 30 are located on the same plane, which can improve the connection strength between the mounting part 44 and the compressor housing 6, and also facilitate the production and manufacturing of the bracket 4.

[0125] like Figure 5 , Figure 7 , Figure 9 and Figure 11 As shown, according to the twelfth embodiment of the present invention, based on any of the above embodiments, the connecting portion 43 is further provided with a hollow portion 45.

[0126] In this design, the connecting part 43 is provided with a hollow part 45, so that the spaces on both sides of the connecting part 43 are connected to allow airflow to pass through.

[0127] In specific applications, the cutout portion 45 includes a through hole, and further, the through hole is arc-shaped or strip-shaped.

[0128] Furthermore, there are multiple hollowed-out portions 45, which are distributed circumferentially along the pivot 1 on the connecting portion 43.

[0129] According to the thirteenth embodiment of the present invention, based on the above embodiment twelve, the cross-sectional shape of the portion of the connecting portion 43 without the hollow portion 45 is the same in any two cross-sections of the plane where the axis of the rotating shaft 1 is located.

[0130] In this design, in any two cross sections of the plane containing the axis of the rotating shaft 1, the cross-sectional shape of the part of the connecting part 43 without the hollow part 45 is the same, that is, the connecting part 43 is a uniform cross-sectional structure, thereby ensuring the balance effect of the connecting part 43 on the force exerted by the bearing 5 and the anti-rotation component 42.

[0131] According to the fourteenth embodiment of the present invention, based on the above embodiment twelve, the portion of the connecting portion 43 without the hollow portion 45 is further characterized by a variable cross-section structure.

[0132] In this design, the portion of the connecting part 43 without the perforated portion 45 has a variable cross-section structure, which facilitates the manufacturing of the connecting part 43. This reduces material usage while increasing the strength of the support 4 and reducing its deformation, thereby improving the vibration and noise issues of the compressor.

[0133] According to the fifteenth embodiment of the present invention, based on the above embodiment twelve, the cross-sectional shape of the connecting part 43 in the plane containing the axis of the rotating shaft 1 includes any one of square, triangle and rhombus.

[0134] In this design, the shape of the connecting part 43 in the cross-section of the plane containing the axis of the rotating shaft 1 includes any one of a square, triangle, or rhombus. This facilitates the manufacturing of the connecting part 43, reduces material usage, increases the strength of the support 4, reduces the deformation of the support 4, and thus improves the vibration and noise problems of the compressor. In specific applications, the cross-section of the portion of the connecting part 43 without the hollowed-out portion 45 in the cross-section of the plane containing the axis of the rotating shaft 1 is formed by any one of a square, triangle, rhombus, or quadrilateral other than square and rhombus. Of course, the cross-sectional shape of the portion of the connecting part 43 without the hollowed-out portion 45 can also be other polygons.

[0135] like Figure 11 and Figure 12 As shown, according to the sixteenth embodiment of the present invention, based on any of the above embodiments, the connecting portion 43 is further provided with a reinforcing rib 46 near the end face of the rotating member 30.

[0136] In this design, the end face of the connecting part 43 near the rotating part 30 is also provided with a reinforcing rib 46, which improves the strength of the connecting part 43 and thus prevents the bracket 4 from deforming due to the force from the bearing 5 and the anti-rotation part 42 during the operation of the compressor.

[0137] In practical applications, in the cross section of the plane passing through the axis of the rotating shaft 1, the reinforcing rib 46 is triangular. One side of the triangular reinforcing rib 46 is attached to the connecting part 43, and the other side is attached to the mounting part 44, which improves the strength of the connecting part 43.

[0138] Furthermore, the reinforcing rib 46 and the connecting part 43 are an integral structure.

[0139] Furthermore, the reinforcing rib 46 and the connecting part 43 are integrally formed.

[0140] According to the seventeenth embodiment of the present invention, based on any of the above embodiments, the anti-rotation component 42 further includes a pin.

[0141] In this design, the anti-rotation component 42 includes a pin, part of which is inserted into the end face of the flat portion 41, and the other part protrudes from the flat portion 41, to prevent the rotating component 30 of the vortex compression portion 3 from rotating. The pin reduces production costs.

[0142] Furthermore, there are multiple anti-rotation components 42.

[0143] In this design, there are multiple anti-rotation components 42. The arrangement of multiple anti-rotation components 42 improves the restriction effect on the rotating component 30 of the scroll compressor 3, and ensures the compression effect of the scroll compressor 3 on the refrigerant.

[0144] Furthermore, multiple anti-rotation components 42 are distributed circumferentially along the rotation axis 1.

[0145] It is understandable that the minimum outer perimeter of the flat portion 41 should include the entire outer diameter of the anti-rotation component 42, so that the anti-rotation component 42 is entirely located within the area of ​​the flat portion 41.

[0146] According to the eighteenth embodiment of the present invention, based on any of the above embodiments, the rotating member 30 further includes a moving scroll.

[0147] In this design, the rotating component 30 includes a moving scroll, which compresses the refrigerant through its rotational motion. The anti-rotation component 42 prevents the moving scroll from rotating during its rotational motion, ensuring the reliability of refrigerant compression.

[0148] Furthermore, the vortex compression section 3 also includes a stationary vortex disk, and the moving vortex disk meshes with the stationary vortex disk to form a compression cavity.

[0149] Understandably, the rotating scroll of the scroll compressor 3 is subjected to centrifugal force and the gas generated by compressing the refrigerant during its rotational motion. This force is transferred to the support 4 via the anti-rotation component 42. Therefore, the support 4 bears the forces from the bearing 5 of the rotating shaft 1 and the anti-rotation component 42. When the compressor operates at high speed, the centrifugal force it experiences increases significantly. Consequently, the support 4 undergoes relatively noticeable local deformation under these forces, leading to a deterioration in compressor noise and vibration. By defining the positional relationship and dimensions of the connecting portion 43 and the flat portion 41, the overall stress on the support 4 can be improved, thereby reducing vibration and noise at high speeds.

[0150] like Figure 4 As shown, according to the nineteenth embodiment of the present invention, based on any of the above embodiments, the compressor further includes: a first housing 6, a motor unit 2 disposed within the first housing 6; a second housing 7, a scroll compressor unit 3 disposed within the second housing 7, a bracket 4 sandwiched between the first housing 6 and the second housing 7, and a mounting portion 44 of the bracket 4 connected to the first housing 6 and the second housing 7, wherein the pressure borne by the first housing 6 is less than the pressure borne by the second housing 7.

[0151] In this design, the compressor also includes a first housing 6 and a second housing 7. The motor unit 2 is disposed within the first housing 6, the scroll compressor unit 3 is disposed within the second housing 7, and the bracket 4 is disposed between the first housing 6 and the second housing 7. The bracket 4 is connected to the first housing 6 and the second housing 7 via a connecting part 43, thereby fixing the bracket 4, reducing the degree of deformation of the bracket 4, and thus reducing vibration or noise caused by deformation. The pressure borne by the first housing 6 is less than that borne by the second housing 7; that is, the first housing 6 is a low-pressure housing, and the second housing 7 is a high-pressure housing. When the compressor is operating normally, gaseous refrigerant enters the low-pressure housing cavity from the compressor's suction port and flows through the motor unit 2 and the bracket 4 to the scroll compressor unit 3. The high-pressure gas formed after the refrigerant passes through the scroll compressor unit 3 is discharged into the compression chamber surrounded by the high-pressure housing and leaves the compressor through the discharge port.

[0152] The twentieth embodiment of the present invention also proposes an air conditioning system provided by an air conditioning system, such as the compressor proposed in any of the above embodiments.

[0153] The air conditioning system provided in the twentieth embodiment of the present invention, having included the compressor proposed in any of the above embodiments, has all the beneficial effects of the compressor.

[0154] Specifically, the air conditioning system also includes a condenser and a heat exchanger. The compressor, condenser and heat exchanger are connected in series to form a heat exchange flow path, and the refrigerant flows in the heat exchange flow path to achieve the cooling or heating effect.

[0155] According to a twenty-first embodiment of the present invention, a vehicle is also provided, comprising: a compressor or air conditioning system as described in any of the above embodiments.

[0156] The vehicle provided in the twenty-first embodiment of the present invention, having all the beneficial effects of the compressor or air conditioning system proposed in any of the above embodiments, has all the beneficial effects of the compressor or air conditioning system.

[0157] It is worth noting that the vehicles can be traditional gasoline-powered vehicles or new energy vehicles. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0158] like Figures 4 to 12 As shown, according to the twenty-second embodiment of this application, this application proposes a compressor, which is an electric compressor, for use in the air conditioning system of an automobile.

[0159] The compressor includes: a motor unit 2, a scroll compressor unit 3, a rotating shaft 1, a bearing 5, and a support 4. The support 4 includes a bearing housing 40, a flat section 41, a connecting section 43, a mounting section 44, a hollow section 45, and an anti-rotation component 42. The motor unit 2 is located inside the compressor and generates torque, including a stator and a rotor. The scroll compressor unit 3 compresses the intake refrigerant, including a stationary scroll and a moving scroll. The rotating shaft 1 is fixed to the rotor and transmits the torque provided by the motor unit 2. The bearing 5 supports the rotational movement of the rotating shaft 1. The support 4 is disposed between the motor unit 2 and the scroll compressor unit 3 for component connection and fixation. The bearing housing 40 is a structure located in the groove in the middle of the support 4 and within its outer wall area, used to fix and support the bearing 5 of the rotating shaft 1. Multiple anti-rotation components are disposed on the support 4, distributed on the side of the support 4 opposite to the moving scroll, to limit the rotation of the moving scroll during circumferential motion. The flat portion 41 is a plane on the bracket 4 used for assembling the anti-rotation component, and it is also the end face of the bearing housing 40 extending axially. The outer periphery of the flat portion 41 includes at least the entire outer diameter of the anti-rotation component. The mounting portion 44 is the upper and lower end face area on the outer side of the bracket 4 used for assembly and sealing. The connecting portion 43 is the connection structure between the mounting portion 44 and the bearing housing 40. The hollow portion 45 is a through hole structure provided in the area of ​​the connecting portion 43 for airflow.

[0160] Specifically, the end face of the connecting portion 43 near the moving scroll plate is not on the same plane as the flat portion 41. In particular, the end face of the flat portion 41 near the moving scroll plate is located between the moving scroll plate and the end face of the connecting portion 43 near the moving scroll plate, that is, the end face of the connecting portion 43 near the moving scroll plate is recessed from the end face of the flat portion 41 near the moving scroll plate to the side away from the moving scroll plate.

[0161] Furthermore, in any cross section of the bracket 4 passing through the central axis of the bearing 5, the geometric center of the cross section within the connection part 43, excluding the hollow part 45, should satisfy: 0.75≤L1 / L2≤1.5.

[0162] Wherein, L1 is the axial length from the geometric center of the cross section of the connecting part 43 to the center of the protruding section of the anti-rotation component 42, and L2 is the axial length from the geometric center of the cross section of the connecting part 43 to the axial center of the bearing 5.

[0163] Furthermore, the upper and lower end faces of the mounting part 44 may or may not be on the same plane as the connecting part 43. Specifically, the upper end face of the mounting part 44 is the end face of the mounting part 44 facing the moving scroll, and the lower end face of the mounting part 44 is the end face of the mounting part 44 facing the motor part 2.

[0164] Furthermore, the upper end face of the mounting part 44 may or may not be on the same plane as the flat part 41.

[0165] Furthermore, in any cross section of the bracket 4 along the central axis of the bearing 5, the cross section of the connecting part 43, excluding the hollow part 45, can be of various irregular shapes.

[0166] Furthermore, in any cross section of the bracket 4 along the central axis of the bearing 5, the cross section of the connecting part 43, excluding the hollow part 45, can be of the same shape or a variable cross section structure of different shapes.

[0167] Furthermore, the bracket 4 has a raised reinforcing rib 46 on the end face of the connecting part 43 near the flat part 41.

[0168] Furthermore, the anti-rotation component 42 is an anti-rotation pin.

[0169] Furthermore, the compressor proposed in this application is an electric compressor suitable for refrigerants R134a (hydrofluorocarbon refrigerant), R744 (carbon dioxide refrigerant), R290 (propane refrigerant) and R1234yf (tetrafluoropropylene refrigerant).

[0170] Specifically, such as Figure 13 As shown, graph F represents the deformation of the compressor in the related art when it operates at high speed, and graph H represents the deformation of the compressor proposed in this application when it operates at high speed. It can be seen that the compressor proposed in this application greatly reduces the deformation of the support.

[0171] This invention discloses an electric compressor for automotive air conditioning. The electric compressor has a first housing 6 (low-pressure housing), a second housing 7 (high-pressure housing), a scroll compressor 3, a motor 2, a bracket 4, an electronic control unit, and a cover plate. When the compressor is running normally, the motor 2 drives the rotating shaft to rotate, which in turn drives the moving scroll of the scroll compressor 3 to rotate circumferentially. During the above operation, due to its own unbalanced structure, the rotating shaft generates centrifugal force during rotation, which tends to be applied to the bearing 5 of the rotating shaft 1. At the same time, the moving scroll is subjected to centrifugal force and gas force generated by compressing the refrigerant during circumferential rotation, and these forces are also transmitted to the anti-rotation component mounted on the bracket 4. Therefore, the bracket 4 bears the forces from the bearing 5 of the rotating shaft 1 and the anti-rotation component. When the compressor runs at high speed, the centrifugal force it experiences increases significantly. Therefore, the bracket 4 will undergo relatively obvious local deformation under these forces, resulting in a deterioration of the compressor's noise and vibration. The compressor proposed in this invention changes the structure and axial dimension distribution of the connection portion 43 between the inner bearing seat 40 and the outer mounting portion 44 of the bracket 4. This improves the overall stress and deformation of the support 4, thereby reducing the vibration and noise of the compressor at high speeds.

The terms "installed," "connected," "linked," and "fixed," etc., should be interpreted broadly.
