Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a compressor intake component, a compressor, and a vehicle. Background Technology

[0002] The compressor is one of the core components of a modern air conditioning system, and its performance directly affects the efficiency and reliability of the entire system. Existing compressors typically consist of a housing and a stator housed within the housing, with suction ports on the housing to allow gas to be drawn in.

[0003] However, in the prior art, when the axial length of the stator increases, it may become incompatible with the housing, which will hinder the intake of gas through the suction port, resulting in problems such as suction pressure loss and reduced cooling capacity in most compressors. Utility Model Content

[0004] This application provides an intake assembly for a compressor, a compressor, and a vehicle. The intake assembly can improve the smoothness of intake, reduce intake pressure loss, and improve the working efficiency and cooling capacity of the compressor.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is: providing a compressor suction assembly, the suction assembly including a housing and a suction ring groove; the housing is provided with a receiving cavity for mounting a stator, and the housing is provided with a suction hole communicating with the receiving cavity and the external environment; the inner wall of the receiving cavity is provided with a plurality of guide grooves, the plurality of guide grooves being spaced apart along a first direction, and when the stator is assembled in the receiving cavity, the first direction is consistent with the circumferential direction of the stator, and the extension direction of the guide grooves is perpendicular to the first direction; the suction ring groove is provided on the inner wall of the receiving cavity along the first direction, and the suction ring groove is directly connected to the suction hole, and the plurality of guide grooves are all connected to the suction ring groove.

[0006] The air intake is also directly connected to one of the guide channels.

[0007] The inner wall of the receiving cavity is also formed with limiting parts spaced apart along the first direction. Along the first direction, the limiting parts are located between two guide grooves. When the stator is assembled in the receiving cavity, the inner side of the limiting parts abuts against the outer side of the stator.

[0008] The suction ring groove passes through the bottom wall and the limiting part of the guide groove. The suction ring groove includes a guide groove on the guide groove and a connecting groove on the limiting part. Along the second direction, the size of the guide groove in the guide groove part of the suction ring groove is smaller than the size of the connecting groove. When the stator is assembled in the receiving cavity, the second direction is consistent with the axial direction of the stator.

[0009] The drainage channel has a first cross-section parallel to the axial direction of the shell, and the connecting channel has a second cross-section parallel to the axial direction of the shell. The cross-sectional area of ​​the first cross-section is less than or equal to the cross-sectional area of ​​the second cross-section.

[0010] The suction ring groove has a third cross section parallel to the axial direction of the shell, and the area of ​​the third cross section is equal to the area of ​​the suction hole.

[0011] The connecting groove is formed by pressing the limiting part outward along the radial direction of the housing, and the outer wall of the housing is provided with a protrusion corresponding to the connecting groove.

[0012] This application also includes a second technical solution, providing a compressor that includes the suction component of the compressor described above.

[0013] The compressor also includes a stator, which is installed in the housing cavity and blocks at least part of the intake port; multiple guide grooves together with the stator form multiple airflow channels to diffuse the high-speed airflow drawn in by the intake port to the inner wall of the housing cavity, and the intake ring groove connects the multiple airflow channels.

[0014] This application also includes a third technical solution, providing a vehicle including the aforementioned compressor.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, the compressor intake assembly, compressor, and vehicle provided in this application include a housing and intake ring grooves. The housing has a receiving cavity for mounting a stator, and an intake port communicating with the receiving cavity and the external environment. The inner wall of the receiving cavity has multiple guide grooves, spaced apart along a first direction. When the stator is assembled in the receiving cavity, the first direction is consistent with the circumferential direction of the stator, and the extension direction of the guide grooves is perpendicular to the first direction. The intake ring grooves are arranged along the first direction on the inner wall of the receiving cavity, and are directly connected to the intake port. All guide grooves are connected to the intake ring grooves. The intake assembly of this application, by providing guide grooves spaced apart along the first direction on the inner wall of the receiving cavity and connecting the guide grooves and the intake port to the intake ring grooves, can improve the smoothness of intake, reduce the resistance to gas flow, and enable more efficient gas flow. Since the extension direction of the guide grooves is perpendicular to the circumferential direction of the stator, the gas can diffuse along the guide grooves towards the inner circumferential wall of the receiving cavity. The above structure reduces the compressor's suction pressure loss and increases the cooling capacity, thereby improving the compressor's efficiency and performance. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0025] Please refer to the reference. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a structure of an embodiment of the air intake component provided in this application. Figure 2 yes Figure 1 A schematic diagram of the structure of the suction ring groove. In one aspect of this application, a suction assembly 10 is provided, comprising a housing 1 and a suction ring groove 2. The housing 1 has a receiving cavity 11 for mounting a pin 30, and a suction hole 12 communicating with the receiving cavity 11 and the external environment. The inner wall of the receiving cavity 11 has multiple guide grooves 13, which are spaced apart along a first direction D1. The suction ring groove 2 is disposed on the inner wall of the receiving cavity 11 along the first direction D1, and is directly connected to the suction hole 12. All the guide grooves 13 are connected to the suction ring groove 2. The suction assembly 10 of this application, by providing guide grooves 13 spaced apart along the first direction D1 on the inner wall of the receiving cavity 11, and connecting the guide grooves 13 and the suction hole 12 to the suction ring groove 2, can improve the smoothness of suction, reduce the resistance to gas flow, and enable more efficient gas flow. Because the extension direction of the guide groove 13 is perpendicular to the circumferential direction of the stator 30, the gas can diffuse along the guide groove 13 towards the inner circumferential wall of the receiving cavity 11. This structure reduces the suction pressure loss of the compressor 100 and increases the cooling capacity, thereby improving the operating efficiency and performance of the compressor 100. It should be noted that when the stator 30 is assembled in the receiving cavity 11, the first direction D1 is consistent with the circumferential direction of the stator 30, and the extension direction of the guide groove 13 is perpendicular to the first direction D1.

[0026] Specifically, normally, when the stator 30 is installed in the receiving cavity 11, the stator 30 will abut against the inner wall of the receiving cavity 11, covering the guide groove 13 and thus hindering the flow of gas. However, in the embodiment of this application, the suction assembly 10, by setting the suction ring groove 2, allows a gap between the inner wall of the receiving cavity 11 and the stator 30. After the suction hole 12 draws in gas, it can flow along the suction ring groove 2 to the multiple guide grooves 13 without being blocked by the outside of the stator 30, thereby improving the smoothness of suction, reducing the resistance to gas flow, and enabling the gas to flow more efficiently.

[0027] When in use, after the air intake hole 12 draws in gas, the gas can continue to flow along the air intake ring groove 2 to the guide groove 13, and then diffuse into the inner wall of the receiving cavity 11 through the guide groove 13.

[0028] Furthermore, even if the axial length of the stator 30 within the receiving cavity 11 increases, this embodiment can still directly connect with the suction port 12 via the suction ring groove 2, improving or avoiding problems such as reduced suction smoothness and suction pressure loss caused by the increased axial length of the stator 30 blocking part or all of the suction port 12. In other words, the suction assembly 10 of this embodiment can be adapted to different models of stator 30, exhibiting high versatility. When the compressor 100 needs to replace stator 30 with different models and lengths, a single housing 1 can be used without developing new molds or housings 1, thus reducing the cost of the compressor 100.

[0029] Furthermore, the multiple guide grooves 13 are evenly spaced on the inner wall of the receiving cavity 11, which can improve the uniformity of gas flow and the uniformity of cooling.

[0030] In one embodiment of this application, the air intake 12 is also directly connected to one of the guide channels 13.

[0031] Specifically, the direct connection between the suction port 12 and the guide channel 13 means that gas entering through the suction port 12 can flow directly into the guide channel 13, reducing gas flow resistance, improving gas flow efficiency, and thus optimizing the gas flow path. Simultaneously, it allows for more effective distribution of the gas flow rate into the receiving cavity 11, thereby enhancing the overall performance and reliability of the compressor 100.

[0032] In one embodiment of this application, a limiting portion 14 is also formed on the inner wall of the receiving cavity 11, which is spaced apart along the first direction D1. Along the first direction D1, the limiting portion 14 is located between two guide grooves 13. When the stator 30 is assembled in the receiving cavity 11, the inner side of the limiting portion 14 abuts against the outer side of the stator 30.

[0033] Specifically, by providing a limiting part 14 on the inner wall of the receiving cavity 11 and abutting it against the outer side of the stator 30, on the one hand, the stator 30 can be effectively positioned and fixed, thereby simplifying the assembly process and improving structural stability; on the other hand, the limiting part 14 may include a protruding structure that protrudes from the inner wall of the receiving cavity 11 relative to the guide groove 13. When abutting against the outer side of the stator 30, since there is a height difference between the guide groove 13 and the limiting part 14 on the inner wall of the receiving cavity 11, the guide groove 13 can avoid the outer side of the stator 30. There is a gap between the guide groove 13 and the stator 30, forming an airflow channel 40 that allows airflow to diffuse and flow towards the inner wall of the receiving cavity 11.

[0034] In one embodiment of this application, as Figure 2 As shown, the suction ring groove 2 penetrates the bottom wall of the guide groove 13 and the limiting part 14. The suction ring groove 2 includes a guide groove 21 located on the guide groove 13 and a connecting groove 22 located on the limiting part 14. Along the second direction D2, the size of the guide groove 21 in the guide groove 13 is smaller than the size of the connecting groove 22. When the stator 30 is assembled in the receiving cavity 11, the second direction D2 is consistent with the axial direction of the stator 30.

[0035] Specifically, since the suction ring groove 2 penetrates the bottom wall of the guide groove 13 and the limiting part 14, when the inner side of the limiting part 14 abuts against the outer side of the stator 30, the suction ring groove 2 can connect two adjacent guide grooves 13, thereby improving the smoothness of suction and reducing the resistance to gas flow. By designing the size of the guide groove 21 to be smaller than that of the connecting groove 22, the cross-sectional area of ​​the guide groove 21 is smaller than that of the connecting groove 22, increasing the pressure of the gas passing through the connecting groove 22. This allows the gas to flow through the connecting groove 22 to the guide groove 21, and then from the guide groove 21 to the guide groove 13, diffusing along the guide groove 13 to the inner wall of the receiving cavity 11. This improves the efficiency of gas flow, optimizes the gas flow path and speed, and helps reduce pressure fluctuations during gas flow, thereby improving overall efficiency, reducing suction pressure loss, and increasing cooling capacity. It should be noted that the cross-sectional area here refers to the area of ​​the guide groove 21 and the connecting groove 22 along the cross-section parallel to the circumference of the housing 1.

[0036] In one embodiment of this application, the drainage channel 21 has a first cross section 211 parallel to the axial direction of the housing 1, and the connecting channel 22 has a second cross section 221 parallel to the axial direction of the housing 1. The cross-sectional area of ​​the first cross section 211 is less than or equal to the cross-sectional area of ​​the second cross section 221.

[0037] Specifically, when gas passes through the guide channel 21, part of it diffuses into the guide channel 13, while the other part continues to flow along the guide channel 21 towards the connecting channel 22. When gas passes through the connecting channel 22, it flows unidirectionally to the adjacent guide channel 21. Therefore, since the area of ​​the first cross-section 211 is less than or equal to the area of ​​the second cross-section 221, the flow rate of the guide channel 21 is less than or equal to the flow rate of the connecting channel 22. This enhances the suction pressure of the connecting channel 22, improving or preventing pressure loss or flow restriction in the connecting channel 22, thereby improving the efficiency and stability of gas flow.

[0038] In one embodiment of this application, the suction ring groove 2 has a third cross section parallel to the axial direction of the housing 1, and the area of ​​the third cross section is equal to the area of ​​the suction hole 12.

[0039] Specifically, the area of ​​the third cross section is the sum of the areas of the first cross section 211 and the second cross section 221. By making the area of ​​the third cross section equal to the area of ​​the suction port 12, the gas flow rate sucked in by the suction port 12 can be balanced, so that the gas can smoothly transition between the suction ring groove 2 and the guide groove 13, achieving pressure balance, uniform flow distribution, reducing suction pressure loss, and improving the stability of gas flow, thereby improving the efficiency, reliability and cooling capacity of the compressor 100.

[0040] In one embodiment of this application, the connecting groove 22 is formed by the limiting part 14 being stamped outward along the radial direction of the housing 1, and the outer wall of the housing 1 is provided with a protrusion 15 corresponding to the connecting groove 22.

[0041] Specifically, by stamping the limiting part 14 to form a connecting groove 22 on the limiting part 14 and a corresponding protrusion 15 on the outer wall of the housing 1, on the one hand, the accuracy and reliability of the position and shape of the connecting groove 22 can be improved, and on the other hand, the depth of the connecting groove 22 on the limiting part 14 can be increased, thereby reducing the resistance to gas flow and improving the efficiency of gas flow.

[0042] Of course, in another embodiment, the connecting groove 22 may also be formed in other ways, such as thinning the limiting part 14, etc. The specific method can be determined according to the actual process requirements, and will not be elaborated here.

[0043] In one specific embodiment, the inner wall of the receiving cavity 11 is provided with six guide grooves 13 and the six guide grooves 13 are connected by the suction ring groove 2. After the setter 30 is installed, the gas can flow through the suction hole 12 along the suction ring groove 2 to the six guide grooves 13 respectively, thereby improving the smoothness of suction, reducing suction pressure loss, and improving the working efficiency and cooling capacity of the compressor 100.

[0044] Of course, in another embodiment, the number of guide channels 13 may also include three, four, five, etc. The specific number and arrangement can be determined according to the actual process conditions, as long as pressure balance can be achieved.

[0045] like Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of one embodiment of the compressor of this application. In another aspect, this application provides a compressor 100, including the suction assembly 10 of the compressor 100 described above. Specifically, since the compressor 100 includes the suction assembly 10 described in the above embodiment, it also has the beneficial effects of the suction assembly 10 described above, which will not be repeated here.

[0046] Furthermore, the compressor 100 also includes a stator 30, which is installed in the receiving cavity 11 and blocks at least part of the suction port 12. Specifically, a plurality of guide grooves 13 together with the stator 30 form a plurality of airflow channels 40 for diffusing the high-speed airflow drawn in by the suction port 12 toward the inner wall of the receiving cavity 11, and the suction ring groove 2 connects the plurality of airflow channels 40.

[0047] The compressor 100 of this application embodiment connects multiple airflow channels 40 through the suction ring groove 2. Therefore, even if the stator 30 blocks at least part of the suction hole 12, the gas sucked in by the suction hole 12 can still be guided to each airflow channel 40 for cooling and diffusion through the suction ring groove 2. This improves or avoids the suction pressure loss caused by the stator 30 blocking the suction hole 12, thereby improving working efficiency and cooling capacity.

[0048] In another aspect, this application also provides a vehicle that includes the compressor 100 described above. Specifically, since the vehicle includes the compressor 100 described in the above embodiments, it also has the beneficial effects of the compressor 100 described above, which will not be repeated here.

Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted. In addition, the orientations or positional relationships indicated by terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships that are commonly used when the product of this application is in use. They are only for the purpose of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0050] It is understood that the term "multiple" in this document means at least two, such as two, three, etc., unless otherwise specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.
