In existing scroll compressors, axial adjustment of the stationary scroll plate leads to unstable meshing between the moving and stationary scroll plates, resulting in friction failure, uneven clearance, and fluid leakage, which affects compression efficiency and reliability.
The design employs a scroll plate assembly with a movable connection between the air intake port and the switching component. The opening and closing of the air intake port is controlled by the switching component, thereby adjusting the volume of the air intake space. This eliminates the need for the stationary scroll plate to move axially relative to the moving scroll plate, thus avoiding meshing deviation and friction failure.
It improves the compression efficiency and reliability of scroll compressors, reduces manufacturing difficulty and cost, extends service life, and avoids fluid leakage caused by increased or uneven gaps.

[0043] Embodiments of the present application
[0044] The technical solutions of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0045] The descriptions of the following embodiments are with reference to the additional drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in the description of the present application, such as “up”, “down”, “front”, “back”, “left”, “right”, “inner”, “outer”, “top surface”, “side surface”, “bottom surface”, “top wall”, “side wall”, “bottom wall”, “inner side wall”, “peripheral side wall”, etc., are only the directions of the additional drawings, therefore, the directional terms used are for better, clearer illustration and understanding of the present application, and are not indicative or implied that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, “connection” and “coupling” are used without specific description, and include direct connection (coupling) and indirect connection (coupling).
[0046] A scroll compressor is a high-efficiency, stable gas compression device with the advantages of small size, simple structure, and easy maintenance, and can provide efficient and stable gas compression effect. Therefore, it is widely used in the industrial field. For example: air compression field, medical instrument field, refrigeration field, air separation field, oil and gas field, air conditioning field, cold storage and refrigerator field, heat pump field, etc. Scroll compressor is a volumetric compression compressor, and the compression components mainly consist of a dynamic scroll plate and a static scroll plate.
[0047] However, in the scroll compressor provided by the related art, the height of the suction space is changed by making the static scroll plate position axially adjustable and axially fixable, so as to achieve the purpose of adjusting the volume of the suction space. This form of variable volume requires moving the static scroll plate, which will affect the meshing state between the dynamic scroll plate and the static scroll plate after moving, causing the static scroll plate to be skewed and friction failure, or causing the gap to become larger or unevenly distributed, resulting in a decrease in compression efficiency.
[0048] Meanwhile, in order to cooperate with the movement of the static scroll plate, the above-mentioned related technology needs to realize the telescopic function through the reset element between the dynamic scroll plate support plate and the dynamic scroll plate surface, and needs to ensure that the deformation of the reset element is uniform on the whole plane to ensure the perfect contact between the dynamic plate support plate and the static scroll plate tooth top. This is difficult to achieve. The cooperation between the dynamic scroll plate support plate and the static scroll plate tooth top is prone to deviation, and thus is prone to friction and leakage. In order to solve the problems in the above-mentioned related technology, a great cost needs to be paid to deal with the coaxial problem, the uneven gap problem and the increased leakage point problem during movement, which leads to the increase of the manufacturing difficulty and manufacturing cost of the scroll compressor. Meanwhile, this structure also has the problems of the decrease of the reliability and service life of the scroll compressor.
[0049] In view of the technical problems in the above-mentioned related technology, the present application provides a scroll plate assembly, a scroll compressor and a vehicle. The static plate member of the scroll compressor does not need to move axially relative to the dynamic plate member to realize the adjustment of the compression volume of the suction space, can avoid the meshing deviation or friction failure problem between the dynamic plate member and the static plate member caused by the movement of the static plate member, can prevent the fluid leakage problem of the suction space formed by the dynamic plate member and the static plate member due to the increase or unevenness of the gap during compression, and is beneficial to ensure the compression efficiency of the scroll compressor. Meanwhile, since the static plate member does not need to move axially relative to the dynamic plate member to realize the adjustment of the compression volume of the suction space, the coaxial problem between the dynamic plate member and the static plate member caused by the movement of the static plate member can be avoided, which is beneficial to reduce the manufacturing difficulty and manufacturing cost of the scroll compressor. The static plate member does not need to move axially relative to the dynamic plate member, which can also improve the reliability and service life of the scroll compressor in use.
[0050] The present application provides a vehicle 90, which comprises a scroll compressor 1000, as shown in FIG. 18, which is a structural block diagram of the vehicle 90 provided by the present application.
[0051] The scroll compressor 1000 provided by the present application will be described in detail below with reference to the accompanying drawings.

[0053] The scroll compressor 1000 provided in the present application comprises a scroll disc assembly 100, a housing member 200, a second scroll disc 300, a connecting member 400 and a driving member 500. The housing member 200 is configured to form an outer shell of the scroll compressor 1000. The scroll disc assembly 100, the second scroll disc 300, the connecting member 400 and the driving member 500 are all arranged in the housing member 200. The scroll disc assembly 100 is fixed in the housing member 200. The second scroll disc 300 is movably arranged in the housing member 200 and cooperates with the scroll disc assembly 100. The connecting member 400 is connected between the second scroll disc 300 and the driving member 500. The driving member 500 is configured to drive the second scroll disc 300 to move through the connecting member 400, so that the second scroll disc 300 and the scroll disc assembly 100 extrude fluid to form compressed fluid. In the embodiment, the scroll disc assembly 100 is a static disc assembly, and the second scroll disc 300 is a dynamic disc.
[0054] The housing member 200 comprises a first housing 201, a second housing 202 and a cover plate 203. The first housing 201 is connected between the second housing 202 and the cover plate 203. The first housing 201 is provided with a whole-machine inlet 204. The second housing 202 is provided with a whole-machine outlet 205. Fluid flows into the scroll compressor 1000 through the whole-machine inlet 204, and the compressed fluid flows out from the whole-machine outlet 205.
[0055] The second scroll disc 300 and the scroll disc assembly 100 are accommodated in the second housing 202. The second scroll disc 300 and the scroll disc assembly 100 are configured to jointly enclose an air suction space 600. The air suction space 600 is configured to compress fluid. Fluid flows into the scroll compressor 1000 through the whole-machine inlet 204, and enters the air suction space 600. The fluid compressed in the air suction space 600 flows out from the whole-machine outlet 205.
[0056] The connecting member 400 comprises a crankshaft 401, a bearing 402 and a slip ring 403. The crankshaft 401 and the bearing 402 are arranged in the first housing 201. The crankshaft 401 is connected between the second scroll disc 300 and the driving member 500. The bearing 402 is sleeved on the crankshaft 401. The slip ring 403 is arranged in the second housing 202. The slip ring 403 is connected between the crankshaft 401 and the second scroll disc 300.
[0057] The driving member 500 is a driving motor. The driving member 500 comprises a motor stator 501 and a motor rotor 502. The motor stator 501 and the motor rotor 502 of the driving member 500 are both arranged in the first housing 201. The driving member 500 drives the crankshaft 401 to drive the second scroll disc 300 to rotate axially, so that the volume of the air suction space 600 enclosed by the second scroll disc 300 and the scroll disc assembly 100 changes, and thus the fluid in the air suction space 600 is compressed.
[0058] During operation, fluid enters the scroll compressor 1000 from the whole machine inlet 204, flows through the drive member 500, then enters the suction space 600 through the gap between the peripheral wall of the second scroll plate 300 and the inner wall of the second housing 202 and the suction hole 21, and after the volume of the suction space 600 changes due to the work of the second scroll plate 300 and the first scroll plate 20, the compressed fluid flows out from the center of the first scroll plate 20 through the exhaust port 24, then realizes oil-gas separation through the exhaust cavity 60 formed between the second housing 202 and the first scroll plate 20, and finally is discharged from the whole machine outlet 205.
[0059] Please refer to FIGS. 3-5, FIG. 4 is a partial cross-sectional view of a scroll compressor 1000 in a closed state according to an embodiment of the present application, and FIG. 5 is a partial cross-sectional view of a scroll compressor 1000 in an open state according to an embodiment of the present application.
[0060] The present application provides a scroll plate assembly 100, which comprises a first scroll plate 20 and a switching component 40.
[0061] In the scroll compressor 1000 provided by the present application, the first scroll plate 20 and the second scroll plate 300 enclose the suction space 600. The first scroll plate 20 is provided with a suction hole 21, the suction hole 21 is in communication with the suction space 600, the switching component 40 is movably connected with the first scroll plate 20, and the switching component 40 is configured to open or close the suction hole 21. Thus, the switching component 40 can be arranged in the suction hole 21 and configured to form an adjustable-bore gas port with the inner wall of the suction hole 21, thereby realizing adjustable compression volume of the suction space 600.
[0062] The scroll assembly 100 provided by the present application, when applied to the scroll compressor 1000, the switch component 40 is movably connected with the first scroll plate 20. Specifically, the switch component 40 is movably arranged in the suction hole 21, so as to open or close the suction hole 21 by the switch component 40. When the switch component 40 moves in the suction hole 21, the opening or closing of the suction hole 21 can be adjusted, so as to control the flow rate of the fluid flowing into the suction space 600, and then adjust the compression volume of the suction space 600. Thus, the scroll assembly 100 provided by the present application, when applied to the scroll compressor 1000, the first scroll plate 20 does not need to move axially relative to the second scroll plate 300 to adjust the compression volume of the suction space 600, which can avoid the problems of the meshing deviation or friction failure between the second scroll plate 300 and the first scroll plate 20 caused by moving the first scroll plate 20, can prevent the problem of fluid leakage caused by the gap between the second scroll plate 300 and the first scroll plate 20 becoming larger or uneven during the compression process, and is beneficial to ensure the compression efficiency of the scroll compressor 1000. At the same time, since the first scroll plate 20 does not need to move axially relative to the second scroll plate 300 to adjust the compression volume of the suction space 600, the coaxial problem between the second scroll plate 300 and the first scroll plate 20 caused by the movement of the first scroll plate 20 relative to the second scroll plate 300 can be avoided, which is beneficial to reduce the manufacturing difficulty and manufacturing cost of the scroll compressor 1000. Moreover, the first scroll plate 20 does not need to move axially relative to the second scroll plate 300, which can also improve the reliability and service life of the scroll compressor 1000.
[0063] It can be understood that the driving of the movement of the switch component 40 includes but is not limited to motor driving or electromagnetic driving. When the motor driving is used, the rotation needs to be changed into linear motion through a transmission structure. When the electromagnetic driving is used, the linear motion is achieved by magnetic attraction or magnetic repulsion. The present application does not limit this.
[0064] Referring to FIGS. 3-5, in some embodiments, at least one of the first scroll plate 20 and the second scroll plate 300 is provided with a suction hole 21 communicating with the suction space 600. The switch component 40 is mounted to the suction hole 21. The switch component 40 is configured to form an adjustable-bore air port with the inner wall of the suction hole 21, so that the switch component 40 can open or close the suction hole 21, thereby realizing adjustable compression volume of the suction space 600. Fluid flows into the scroll compressor 1000 through the machine inlet 204, enters the suction space 600 from the suction hole 21, and then flows out from the machine outlet 205 after being compressed by the suction space 600. In other words, the suction hole 21 can be provided in either the first scroll plate 20 or the second scroll plate 300, or both the first scroll plate 20 and the second scroll plate 300, and the suction hole 21 communicates with the suction space 600 formed by the first scroll plate 20 and the second scroll plate 300.
[0065] Referring to FIGS. 3-5, in the present embodiment, the first scroll plate 20 is taken as an example of the static scroll plate, and the second scroll plate 300 is taken as an example of the dynamic scroll plate. It can be understood that in some other embodiments, the first scroll plate 20 can be a dynamic scroll plate, and the second scroll plate 300 can be a static scroll plate, which is not limited in the present application.
[0066] Referring to FIGS. 3-5, in one embodiment, the position of the suction hole 21 and the position of the switch component 40 are at least partially overlapped in the axial direction of the first scroll plate 20. By at least partially overlapping the suction hole 21 and the switch component 40 in the axial direction of the first scroll plate 20, the area of the overlapping part of the switch component 40 and the suction hole 21 can be adjusted during the movement of the switch component 40, so as to control the flow rate of the fluid flowing into the suction space 600, thereby realizing adjustment of the compression volume of the suction space 600.
[0067] Further, the switch component 40 is movably arranged in the axial direction of the first scroll plate 20. By movably arranging the switch component 40 in the axial direction of the first scroll plate 20, and at least partially overlapping the suction hole 21 and the switch component 40 in the axial direction of the first scroll plate 20, the area of the overlapping part of the switch component 40 and the suction hole 21 can be adjusted during the movement of the switch component 40 in the axial direction of the first scroll plate 20, so as to more accurately control the flow rate of the fluid flowing into the suction space 600, thereby improving the accuracy of the adjustment of the compression volume of the suction space 600.
[0068] Please refer to FIG. 3 to FIG. 5, in the scroll set 100 provided by the embodiment, the suction hole 21 is arranged on the first scroll 20. Part of the switch component 40 is arranged in the exhaust cavity 60 on the side of the first scroll 20 away from the second scroll 300, and the other part of the switch component 40 is movably arranged in the suction hole 21. By adjusting the insertion depth of the part of the switch component 40 in the suction hole 21, the size of the caliber surrounded by the part of the switch component 40 in the suction hole 21 and the inner wall of the suction hole 21 can be changed, so that the compression volume of the suction space 600 can be adjusted.
[0069] In the scroll set 100 provided by the embodiment, the first scroll 20 comprises a first disc body 22 and a first scroll tooth 23. The first scroll tooth 23 is arranged on the side of the first disc body 22 facing the second scroll 300. The first scroll tooth 23 is in a spiral shape. The first scroll tooth 23 extends spirally from the center of the first disc body 22 to the peripheral side. The suction hole 21 is arranged on the first disc body 22 and extends to the first scroll tooth 23, that is, the suction hole 21 penetrates the first disc body 22 and is partially arranged on the first scroll tooth 23. The opening of the suction hole 21 on the side of the first scroll 20 facing the second scroll 300 is completely located on the first scroll tooth 23, and the opening of the suction hole 21 on the side of the first scroll 20 facing the second scroll 300 is located on the first scroll tooth 23 close to the first disc body 22. The first scroll tooth 23, the first disc body 22 and the second scroll 300 enclose the suction space 600 of the scroll compressor 1000, and the suction hole 21 communicates with the suction space 600. Part of the switch component 40 is arranged on the side of the first disc body 22 away from the first scroll tooth 23, and the other part of the switch component 40 is movably arranged along the axial direction of the first disc body 22, so that the other part of the switch component 40 can open or close the suction hole 21, so that the size of the caliber surrounded by the part of the switch component 40 in the suction hole 21 and the inner wall of the suction hole 21 can be changed, thereby adjusting the compression volume of the suction space 600.
[0070] Please refer to FIG. 3 to FIG. 5, in an embodiment, the opening of the suction hole 21 on the side of the first disc body 22 away from the second scroll 300 corresponds to the first scroll tooth 23, that is, the suction hole 21 is a hole cut on the first disc body 22 and the first scroll tooth 23, and one wall surface of the suction hole 21 is arranged in the same plane with one side wall of the first scroll tooth 23, so as to form the opening of the suction hole 21 on the side of the first scroll 20 facing the second scroll 300 completely on the first scroll tooth 23 (that is, one end of the suction hole 21 penetrates the spiral peripheral surface of the first scroll tooth 23 to form the opening on the spiral peripheral surface of the first scroll tooth 23. The spiral peripheral surface is also the tooth surface of the first scroll tooth 23).
[0071] Specifically, the scroll disc assembly provided by the embodiment has the following technical effects. The length of the suction hole 21 in the axial direction perpendicular to the first scroll disc 20 decreases in the direction from the first disc body 22 to the first scroll tooth 23. In other words, the suction hole 21 is wedge-shaped. The switch component 40 includes a wedge-shaped block. The wedge-shaped block is movably arranged in the suction hole 21. The driving member 43 is configured to control the insertion depth of the wedge-shaped block in the suction hole 21. When the wedge-shaped block is completely arranged in the suction hole 21, the wedge-shaped block is located on the surface of the suction hole 21 and is coplanar with the tooth surface of the first scroll tooth 23, that is, when the wedge-shaped block is completely arranged in the suction hole 21, the wedge-shaped block is located on the surface of the suction hole 21 at the opening of the first scroll tooth and is coplanar with the tooth surface of the first scroll tooth 23. Since the wedge-shaped block is located on the surface of the suction hole 21 and is coplanar with the tooth surface of the first scroll tooth 23, the tooth surface structure of the first scroll tooth 23 is complete, the first scroll tooth 23 does not have a recess at the suction hole 21, the arrangement of the suction hole 21 does not affect the compression volume of the suction space 600, and the scroll compressor 1000 does not have an additional clearance volume. Therefore, when the wedge-shaped block is completely arranged in the suction hole 21, the volume efficiency loss of the suction space 600 of the scroll compressor 1000 is almost 0. Moreover, the assembly between the switch component 40 and the first scroll disc 20 is simple, the sealing between the switch component 40 and the first scroll disc 20 is simple, and additional leakage is not easy to occur. In this way, the scroll disc assembly 100 has a smaller calculation of the isentropic efficiency of the scroll compressor 1000. At the same time, since the scroll disc assembly 100 provided by the embodiment has a simple structure and assembly of the variable-volume control part of the scroll compressor 1000, the scroll compressor 1000 has high reliability, and the structure of the variable-volume control part is static and does not increase the additional energy consumption of the driving member 500, so that the energy utilization rate is high.

[0073] The scroll disc assembly 100 provided by the embodiment includes the suction hole 21, which includes a first opening 211 and a second opening 212. The first opening 211 is arranged on the side of the first disc body 22 away from the first scroll tooth 23.

The inner wall of the suction hole 21 includes a first inclined surface 213. The switch component 40 includes a second inclined surface 41 and a connecting surface 42 connected to each other (wherein the two sides of the second inclined surface 41 are connected to the connecting surface 42 through two intermediate surfaces 47, respectively). When the first inclined surface 213 is in contact with the second inclined surface 41, the switch component 40 closes the first opening 211 and the second opening 212 (i.e., the switch component 40 disconnects the first opening 211 and the second opening 212), and the connecting surface 42 is located in the second opening 212 and is coplanar with part of the first scroll tooth 23 (i.e., the connecting surface 42 is coplanar with the tooth surface of the first scroll tooth 23 forming the second opening 212). By arranging the connecting surface 42 in the second opening 212 and coplanar with part of the first scroll tooth 23 when the switch component 40 closes the first opening 211 and the second opening 212, the tooth surface structure of the first scroll tooth 23 is complete, and recesses are avoided at the second opening 212, so that the compression volume of the suction space 600 is not affected, and additional clearance volume is not brought to the scroll compressor 1000 formed by the scroll disc assembly 100. Therefore, when the switch component 40 closes the suction hole 21, the volume efficiency loss of the suction space 600 of the scroll compressor 1000 is almost 0.

[0080] The scroll plate assembly 100 provided by the embodiment has a plurality of suction holes 21. In the scroll compressor 1000 formed by the scroll plate assembly 100, the first scroll plate 20 and the second scroll plate 300 surround to form a plurality of suction spaces 600. At least one suction hole 21 is in communication with one suction space 600. By virtue of the plurality of suction holes 21 and the plurality of suction spaces 600, at least one suction hole 21 is in communication with one suction space 600, that is, each suction space 600 is in communication with at least one suction hole 21, so that each suction space 600 can compress fluid, which is conducive to improving the compression efficiency of the scroll compressor 1000.
[0081] The scroll plate assembly 100 provided by the embodiment forms the scroll compressor 1000, and the scroll compressor 1000 has a plurality of switch components 40. Each switch component 40 is matched with a corresponding suction hole 21. By virtue of the fact that each suction space 600 is in communication with at least one suction hole 21 and each suction hole 21 is matched with one switch component 40, the compression volume of each suction space 600 of the scroll compressor 1000 can be adjusted, thereby facilitating the adjustment of the compression volume of the scroll compressor 1000.
[0082] Please refer to FIG. 9 to FIG. 17. In some embodiments, the number of suction holes 21 in communication with each suction space 600 is a plurality, and the number of suction holes 21 in communication with each suction space 600 is equal. For example, the number of suction holes 21 in communication with each suction space 600 is two, or the number of suction holes 21 in communication with each suction space 600 is three, and the like, which are not limited in the present application.
[0083] Please refer to FIG. 9 to FIG. 17, in some embodiments, the first scroll disc 20 is provided with suction holes 21 at intervals of 90°, so that the plurality of suction holes 21 are uniformly distributed on the first disc body 22 and the first scroll tooth 23. In this way, the plurality of suction holes 21 are periodically and uniformly arranged on the first disc body 22 and the first scroll tooth 23, so that the scroll compressor 1000 has higher stability during the compression of the fluid, which is conducive to reducing the noise generated during the operation of the scroll compressor 1000.
[0084] It should be understood that the plurality of switching components 40 corresponding to the plurality of suction holes 21 are sliding valves, and the movement of the switching component 40 can make the switching component 40 and the inner wall of the suction hole 21 form an adjustable caliber, thereby realizing the adjustable compression volume of the suction space 600. When the switching component 40 is fully closed, the second inclined surface 41 of the switching component 40 is in close contact with the first inclined surface 213 of the corresponding suction hole 21, so that the suction hole 21 is completely closed, that is, the switching component 40 and the wall surface of the suction hole 21 can be completely in close contact, and the connecting surface 42 of the switching component 40 cooperates with the tooth surface of the first scroll tooth 23, that is, the connecting surface 42 is coplanar with the tooth surface of the second opening 212 formed in the first scroll tooth 23, so that the entire tooth surface structure of the first scroll tooth 23 is complete. In this way, the leakage of the suction space 600 can be prevented.
[0085] Please refer to FIG. 9 to FIG. 17, specifically, the switching component 40 includes a driving member 43 and an adjusting member 44. The driving member 43 is connected with the adjusting member 44. The driving member 43 is configured to control the depth of the adjusting member 44 inserted into the suction hole 21. The driving member 43 is arranged on the side of the second part 222 away from the second part 222. The adjusting member 44 is movably arranged in the first channel 221a communicating with the suction hole 21. One end of the driving member 43 is located on the side of the second part 222 away from the first part 221, that is, one end of the driving member 43 is arranged in the exhaust cavity 60 formed between the second part 222 and the second housing 202. The other end of the driving member 43 penetrates the second part 222 and is fixedly connected with the second part 222. The adjusting member 44 is movably connected with the driving member 43 on the side of the second part 222 facing the first part 221, and the adjusting member 44 is movably accommodated in the first channel 221a, and the adjusting member 44 is configured to be movably inserted into the suction hole 21. In order to ensure the sealing performance between the driving member 43 and the second part 222, a sealing member is arranged between the driving member 43 and the second part 222, so that the sealing performance between the driving member 43 and the second part 222 is better. The adjusting member 44 is a wedge-shaped block, and the adjusting member 44 is movably arranged in the suction hole 21, so that the caliber formed by the adjusting member 44 of the switching component 40 and the inner wall of the suction hole 21 is adjustable, thereby realizing the adjustable compression volume of the suction space 600. Therefore, the assembly between the switching component 40 and the first scroll disc 20 is simple and convenient, and has good sealing performance.
[0086] Referring to FIGS. 9-17, in one embodiment, the switch component 40 further comprises a reset member 45. The reset member 45 is connected between the driving member 43 and the adjusting member 44. The reset member 45 is configured to withdraw the adjusting member 44 from the air inlet hole 21 after the adjusting member 44 extends into the air inlet hole 21, so as to enable the switch component 40 to open or close the air inlet hole 21.
[0087] Specifically, the switch component 40 drives the adjusting member 44 to move along the axial direction of the first scroll 20 by electromagnetic drive, so as to realize the opening or closing of the air inlet hole 21 by the adjusting member 44. The reset member 45 is an elastic member, and the reset member 45 is configured to elastically connect between the driving member 43 and the adjusting member 44.
[0088] Referring to FIGS. 9-17, in the scroll assembly 100 provided in the embodiment, the first scroll tooth 23 comprises an inner tooth surface 231 and an outer tooth surface 232. The inner tooth surface 231 and the outer tooth surface 232 are arranged opposite to each other along the radial direction of the first scroll tooth 23. The first scroll tooth 23 further comprises a tooth head 233 and a tooth tail 234. The tooth head 233 is arranged at the air outlet 24 close to the center of the first portion 221. The first scroll tooth 23 extends spirally from inside to outside. The tooth tail 234 is arranged at the circumferential side of the first portion 221. In the two symmetrical air inlet spaces 600, the opening of the air inlet hole 21 on one air inlet space 600 is arranged on the inner tooth surface 231, and the opening of the air inlet hole 21 on the other air inlet space 600 is arranged on the outer tooth surface 232.
[0089] Specifically, as shown in FIG. 15, the suction space 600 comprises a first cavity 601, a second cavity 602, a third cavity 603 and a fourth cavity 604 arranged in sequence. The first cavity 601 and the second cavity 602 are symmetrically arranged. The third cavity 603 and the fourth cavity 604 are symmetrically arranged. One suction hole 21 is arranged on the outer tooth surface 232 of the first scroll tooth 23 forming the first cavity 601, and one suction hole 21 is arranged on the inner tooth surface 231 of the first scroll tooth 23 forming the second cavity 602. Among them, the suction hole 21 communicating with the first cavity 601 and the suction hole 21 communicating with the second cavity 602 are spaced apart by 180° in the spiral direction on the first scroll tooth 23, that is, the suction hole 21 communicating with the first cavity 601 and the suction hole 21 communicating with the second cavity 602 are arranged opposite in the radial direction of the first scroll tooth 23. Two suction holes 21 are arranged on the outer tooth surface 232 of the first scroll tooth 23 forming the third cavity 603, and two suction holes 21 are arranged on the inner tooth surface 231 of the first scroll tooth 23 forming the fourth cavity 604. Among them, one suction hole 21 communicating with the third cavity 603 is spaced apart by 90° from the suction hole 21 communicating with the second cavity 602 in the spiral direction, and the other suction hole 21 communicating with the third cavity 603 is spaced apart by 180° from the suction hole 21 communicating with the second cavity 602 in the spiral direction. One suction hole 21 communicating with the fourth cavity 604 is spaced apart by 90° from the other suction hole 21 communicating with the third cavity 603 in the spiral direction, and the other suction hole 21 communicating with the fourth cavity 604 is spaced apart by 180° from the suction hole 21 communicating with the third cavity 603 in the spiral direction.
[0090] In other words, starting from the tooth tail 234 of the first scroll tooth 23, every 90° of the tooth surface of the first scroll tooth 23 is provided with a suction hole 21. In order to ensure that there is a nearly symmetrical intake state in each symmetrical closed suction space 600, every 180° of each pair of symmetrically arranged closed suction spaces 600 needs to change the opening position of the suction hole 21, so that the opening positions of the suction holes 21 are distributed on the inner tooth surface 231 or the outer tooth surface 232 of the first scroll tooth 23, respectively. From the tooth tail 234 to the tooth head 233 of the first scroll tooth 23, if the openings of the initial two suction holes 21 are arranged on the inner tooth surface 231 of the first scroll tooth 23, then the openings of the next two suction holes 21 need to be arranged on the outer tooth surface 232 of the first scroll tooth 23, and so on.
[0091] It should be understood that the designer can determine the position of the last suction hole 21 on the first scroll tooth 23 according to the range of the required capacity variation. Since the central suction space 600 of the scroll compressor 1000 is in communication with the discharge chamber 60 and has substantially no compression work function, the suction hole 21 can be arranged in the first and second chambers 601 and 602 that are immediately adjacent to the central suction space 600 at most. According to different capacity variation requirements, the interval between the suction holes 21 in the spiral direction can be set to other values less than or greater than 90°, and the width of the suction hole 21 can also be set to different values, which are not limited in the present application.
[0092] Referring to FIGS. 9 to 17, in some embodiments, the first scroll tooth 23 includes an inner tooth surface 231 and an outer tooth surface 232. The inner tooth surface 231 and the outer tooth surface 232 are arranged opposite to each other in the radial direction of the first scroll tooth 23. The opening of each suction hole 21 is arranged on the inner tooth surface 231, or the opening of each suction hole 21 is arranged on the outer tooth surface 232, which is not limited in the present application. By setting the opening position of the suction hole 21 on the first scroll tooth 23 to be all on the inner tooth surface 231 or all on the outer tooth surface 232, instead of switching the opening direction every 180° in the spiral direction. Thus, suction capacity variation can be performed in only one of the pair of suction spaces 600 at all times, and the other suction space 600 is still normally compressed, which is beneficial to improve the symmetry of the compression parameters in the chambers when the two symmetrical suction spaces 600 move to the discharge port 24 of the first scroll plate 20, and is beneficial to optimize the discharge performance, thereby achieving the effect of noise reduction of the scroll compressor 1000 in the working process.
[0093] Referring to FIGS. 4 to 7, FIGS. 4 and 5 show the completely closed and partially open states of the switching component 40, FIGS. 4 and 6 correspond to the case that the scroll compressor 1000 is not capacity varied when the switching component 40 is completely closed, and FIGS. 5 and 7 correspond to the case that the scroll compressor 1000 is partially capacity varied when the switching component 40 is partially open.
[0094] It needs to be understood that, without changing the geometric size and distribution density of the suction holes 21, the variable capacity of the scroll compressor 1000 can be realized by adjusting the switching state and opening size of the switching components 40. When the scroll compressor 1000 needs to be variable, the switching and opening state of the switching components 40 can be reasonably designed according to the target displacement. Generally, when the displacement of the scroll compressor 1000 changes from large to small, the switching components 40 at the suction holes 21 of the first, second, …, N suction spaces 600 can be opened in turn (starting from the tail 234 and ending at the head 233). Generally, one target displacement can only open one pair of symmetrically located suction holes 21 of the suction space 600 (the suction holes 21 of the suction space 600 at other positions are closed), and if necessary, several pairs of adjacent suction holes 21 of the suction space 600 can be opened together. Here, many types of variable capacity can be derived according to the target demand to achieve different variable capacity effects of the scroll compressor 1000.
[0095] The present application can realize the variable capacity of the scroll compressor 1000 within a certain range by arranging several pairs of symmetric suction holes 21 and switching components 40. By designing different switching states and opening sizes of the switching components 40, and arranging different numbers and widths of the suction holes 21, the continuous variable capacity of the scroll compressor 1000 in different states can be realized.
[0096] In some other embodiments, the suction holes 21 of the scroll compressor 1000 can be arranged on the second scroll plate 300. The switching components 40 are arranged on the side of the second scroll plate 300 away from the first scroll plate 20, and the switching components 40 are movably arranged in the suction holes 21.
[0097] The second scroll plate 300 includes a second plate body 31 and a second scroll tooth 32, and the second scroll tooth 32 is arranged on the side of the second plate body 31 facing the first scroll plate 20. The suction holes 21 pass through the second plate body 31 and at least part of the second scroll tooth 32, and the openings of the suction holes 21 on the side of the second scroll plate 300 facing the first scroll plate 20 are completely located on the second scroll tooth 32.
[0098] In the scroll compressor 1000 provided by the present embodiment, the structure of the suction holes 21 and the switching components 40 arranged on the first scroll plate 20 is changed to be arranged on the second scroll plate 300, and the structures of the suction holes 21 and the switching components 40 are similar to those of the suction holes 21 and the switching components 40 arranged on the first scroll plate 20 described above, which will not be described here.
[0099] The channel connecting the suction hole 21 can be arranged on the side wall surface of the back pressure cavity of the second disc body 31 away from the first disc body 22, or on the upper end annular surface of the back pressure cavity, or on both of the above-mentioned positions.
[0100] The suction hole 21 is arranged periodically at the tooth bottom position of the second vortex tooth 32, and penetrates the tooth surface of the second vortex tooth 32, so that the opening of the suction hole 21 is located on the second vortex tooth 32. Part of the switching component 40 is arranged in the back pressure cavity of the second disc body 31 away from the first disc body 22, and the other part of the switching component 40 is movably extended into the suction hole 21.
[0101] If the second vortex disc 300 does not need to be axially dynamically adjusted (i.e. the second vortex disc 300 is axially fixed), no additional channel similar to the first channel 221a described above needs to be arranged on the second vortex disc 300. After the fluid enters from the channel connecting the suction hole 21, it directly enters the suction hole 21 through the back pressure cavity of the second disc body 31 away from the first disc body 22, and then enters the suction space 600.
[0102] If the back pressure cavity of the second disc body 31 away from the first disc body 22 needs to be used to axially dynamically adjust the second vortex disc 300, a channel similar to the inlet 221b described above needs to be arranged in the second vortex disc 300. At this time, the channel connecting the suction hole 21 needs to be arranged on the outer wall surface of the second disc body 31.
[0103] The above is part of the embodiments of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which are also considered to be within the scope of protection of the present application.
