Abstract
Description
Technical Field
[0001] This invention relates to the field of compressor equipment technology, specifically to a pump assembly, a compressor, and an air conditioner. Background Technology
[0002] Refer to the pump body structure in existing rolling rotor compressors. Figure 1 and Figure 2 The pump body structure includes components such as cylinder A, crankshaft B, compression spring C, vane D, and roller E. Cylinder A has a vane groove for mounting vane D, an inner cavity for mounting roller E, and a spring hole for mounting compression spring C. Roller E and crankshaft B are eccentrically positioned in the inner cavity of cylinder A. Vane D is mounted in the vane groove of the cylinder. Compression spring C is interference-fitted into the spring hole of the cylinder at its tail. The head of the compression spring contacts the tail of the vane, and the spring force makes vane D and roller E fit tightly together.
[0003] However, due to inherent errors in the actual machining of the cylinder spring hole position, the spring hole cannot be perfectly centered in the cylinder thickness direction. Excessive offset can lead to unstable pump operation, misfitting vanes and rollers, vane impact noise, and reduced compressor performance. Secondly, when the cylinder spring hole is not centered, the gap between the spring head and the vane tail groove causes misalignment between the spring head and tail after installation. This misalignment results in bending in the middle of the spring, which can easily scrape against the inner wall of the spring hole, leading to spring wear and failure, and reducing the reliability of the compressor.
[0004] Therefore, existing technologies need further development. Summary of the Invention
[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a pump body assembly, compressor and air conditioner to solve the technical problem in the related art that the spring hole cannot be completely centered in the cylinder thickness direction, and the resulting offset will cause the pump body to run unstablely.
[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: a pump body assembly is provided, including a cylinder, the cylinder being provided with a slide groove for mounting a slide and an inner cavity for mounting a roller, the pump body assembly further including: an elastic positioning component; the cylinder is also provided with a positioning groove for mounting the elastic positioning component, the positioning groove and the slide groove being coaxially arranged, the elastic positioning component abutting against the slide, and being used to push the slide to move along the axis in the slide groove through its own elastic force, and to keep the slide and the roller in contact.
[0007] Furthermore, the two sides of the elastic positioning component are aligned with the two reference planes of the cylinder, and the connection between the elastic positioning component and the slide is located on the central axis of the slide.
[0008] Furthermore, the elastic positioning assembly also includes a mounting base and an elastic element disposed on the mounting base. The mounting base is snapped into the positioning groove, and the elastic element is vertically disposed on the mounting base and coaxial with the central axis of the slide.
[0009] Furthermore, the elastic positioning assembly also includes a guide rod, which is vertically fixed on the mounting base, and the elastic element is sleeved on the guide rod; the guide rod is coaxial with the central axis of the slide.
[0010] Furthermore, the positioning groove has a rectangular cross-section, and an opening connected to the sliding plate groove is provided on the side wall of one short side of the rectangle; the mounting base is snapped onto the side wall of the other short side of the rectangle, and after snapping, the guide rod points towards the sliding plate groove.
[0011] Furthermore, the elastic element is a spring assembly, which is sleeved on the guide rod. The guide rod is arranged along the central axis of the mounting base, and the central axis of the mounting base coincides with the central axis of the slider.
[0012] Furthermore, the slider is provided with a guide hole. When the slider moves in the slider groove, the guide hole slides along the guide rod, thereby guiding and restricting the movement of the slider.
[0013] Furthermore, the mounting base includes a snap-fit seat and a reinforcing plate, which are fitted together. The positioning groove includes a first positioning groove and a second positioning groove. The snap-fit seat is located in the first positioning groove, and the reinforcing plate and the spring assembly are both located in the second positioning groove. The guide rod is fixed on the reinforcing plate. The lateral dimension of the first positioning groove is equal to the lateral dimension of the snap-fit seat, and the lateral dimension of the first positioning groove is greater than the lateral dimension of the second positioning groove, so that the snap-fit seat can snap into the first positioning groove to reinforce the elastic positioning assembly.
[0014] Furthermore, the lateral dimension of the reinforcing plate is equal to the lateral dimension of the second positioning groove.
[0015] Furthermore, the spring assembly includes a first spring and a guide ring. The first spring is fixed on the mounting base, and the guide ring has a through hole. The guide rod passes through the first spring and the through hole in sequence and is inserted into the guide hole. The diameter of the through hole is smaller than the diameter of the first spring, thereby preventing the first spring from twisting.
[0016] Furthermore, the spring assembly also includes a second spring, which is disposed at the end of the guide ring away from the first spring, and the free length of the second spring is less than the free length of the first spring.
[0017] Furthermore, the slider is also provided with two relief grooves, which are symmetrically distributed on both sides of the guide hole. When the spring assembly is in a compressed state, the end of the second spring extends into the relief groove.
[0018] Furthermore, when the spring assembly is in its maximum compressed state, the sum of the total length of the spring assembly and the length of the guide hole is greater than the length of the guide rod; when the spring assembly is in its minimum compressed state, the total length of the spring assembly is less than the length of the guide rod.

[0023] 2. The pump body assembly of the present invention maintains a stable fit between the sliding vane and the roller, avoiding impact noise caused by the sliding vane shifting or vibrating during operation, and improving the operating noise level of the compressor.
[0024] 3.

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0041] According to an embodiment of the present invention, a pump body assembly is provided; please refer to... Figures 3 to 11The pump assembly includes a cylinder 1, which has a slide groove 11 for mounting a slide 2 and an inner cavity for mounting a roller 13. The pump body assembly also includes an elastic positioning component 3. The cylinder 1 also has a positioning groove 12 for mounting the elastic positioning component 3. The positioning groove 12 is coaxially arranged with the slide groove 11. The elastic positioning component 3 abuts against the slide 2 and is used to push the slide 2 along the axis within the slide groove 11 through its own elastic force, keeping the slide 2 in contact with the roller 13. Figure 1 and Figure 2 As shown, in a traditional rolling rotor compressor, the spring hole is located in the cylinder thickness direction, but due to machining errors, the spring hole may not be perfectly centered. This spring misalignment leads to the following problems: poor contact between the vane and the roller, causing deviation in the vane's movement trajectory; and the spring bending or arching due to uneven force in the middle, potentially scraping the inner wall of the spring hole, accelerating wear and reducing lifespan. To address these problems, this embodiment provides an improved pump body assembly. An elastic positioning component 3 is installed in a positioning groove 12, and the positioning groove 12 is coaxially arranged with the vane groove 11. The elastic force of the elastic positioning component 3 pushes the vane 2 to move along the axis within the vane groove 11, keeping the vane 2 in contact with the roller 13. Through the elastic force provided by the elastic positioning component 3, the vane 2 moves along a centered trajectory within the vane groove 11, ensuring stable contact between the vane 2 and the roller 13 in the cylinder 1, thus solving the problem of vane misalignment caused by machining errors. The pump body assembly of this embodiment solves the technical problem in related technologies where the spring hole cannot be perfectly centered in the cylinder thickness direction, resulting in unstable pump operation due to misalignment.
[0042] See Figure 3 and Figure 4 In this embodiment, the pump body assembly has the elastic positioning component 3 aligned with the two reference planes of the cylinder 1 on both sides, and the connection between the elastic positioning component 3 and the slide 2 is located on the central axis of the slide 2. The two reference planes of the elastic positioning component 3 are designed to be perfectly aligned with the two reference planes of the cylinder 1, providing a precise reference for the movement of the slide 2. That is, refer to... Figure 4 From the perspective of [unclear context], the distance H1 between the two reference planes of the elastic positioning component 3 is equal to the distance H2 between the two reference planes of the cylinder 1. The two reference planes of the cylinder 1 are finished by precision machining, possessing high precision and flatness, ensuring the accuracy of the installation position of the elastic positioning component 3. The sliding vane groove 11 and the positioning groove 12 are used to install the sliding vane 2 and the elastic positioning component 3, respectively. The connection between the elastic positioning component 3 and the sliding vane 2 is located on the central axis of the sliding vane 2. The shape and size of the positioning groove 12 match the elastic positioning component 3, and the elastic positioning component 3 will not deviate in the thickness direction of the cylinder 1 (that is, the two reference planes of the cylinder 1), thereby ensuring that the force center line of the elastic positioning component 3 and the sliding vane 2 is always consistent, thus improving the smoothness of pump operation, reducing noise, and improving compressor performance.
[0043] See Figure 5 In this embodiment, the pump body assembly, specifically the elastic positioning component 3, further includes a mounting base 31 and an elastic element disposed on the mounting base 31. The mounting base 31 is snapped into the positioning groove 12, and the elastic element is vertically disposed on the mounting base 31 and coaxial with the central axis of the sliding vane 2. The vertical placement of the elastic element on the mounting base 31 provides a reliable elastic force transmission path, further enhancing the stability of the sliding vane 2's movement within the sliding vane groove 11. This snap-fit method simplifies the installation process and improves the assembly efficiency and structural reliability of the pump body assembly.
[0044] See Figure 5 In this embodiment, the pump body assembly, the elastic positioning assembly 3 also includes a guide rod 33, which is vertically fixed on the mounting base 31, and the elastic element is sleeved on the guide rod 33; the guide rod 33 is coaxial with the central axis of the slide plate 2, further refining the direction of action of the elastic element on the slide plate 2.
[0045] See Figure 5 In this embodiment, the pump body assembly has a rectangular cross-section for the positioning groove 12. An opening connected to the sliding vane groove 11 is provided on the side wall where one short side of the rectangle is located. The mounting base 31 is snapped onto the side wall where the other short side of the rectangle is located. After snapping, the guide rod 33 points to the sliding vane groove 11, so as to achieve precise contact between the guide rod 33 and the elastic element and the sliding vane 2.
[0046] See Figure 5 In this embodiment, the pump body assembly uses a spring assembly 32 as the elastic element. The spring assembly 32 is sleeved on the guide rod 33, which is arranged along the central axis of the mounting base 31. The central axis of the mounting base 31 coincides with the central axis of the slide plate 2. The guide rod 33 ensures the axial stability of the spring assembly 32, preventing spring misalignment or uneven force distribution, thus improving the performance of the elastic positioning assembly 3. Furthermore, the coincidence of the central axis of the mounting base 31 with the central axis of the slide plate 2 further enhances the accuracy of the slide plate 2's movement.
[0047] See Figure 5 and Figure 10 In this embodiment of the pump body assembly, the slide plate 2 is provided with a guide hole 21. When the slide plate 2 moves in the slide plate groove 11, the guide hole 21 slides along the guide rod 33, thereby guiding and restricting the movement of the slide plate 2 by the guide rod 33, which significantly reduces the deviation or vibration problems that occur during the operation of the slide plate 2.
[0048] See Figure 6 and Figure 7In this embodiment, the pump body assembly includes a mounting base 31 comprising a snap-fit base 311 and a reinforcing plate 312, which are fitted together. The positioning groove 12 includes a first positioning groove 121 and a second positioning groove 122. The snap-fit base 311 is located in the first positioning groove 121, and the reinforcing plate 312 and the spring assembly 32 are both located in the second positioning groove 122. The guide rod 33 is fixed on the reinforcing plate 312. The lateral dimension of the first positioning groove 121 is equal to the lateral dimension of the snap-fit base 311, and the lateral dimension of the first positioning groove 121 is greater than the lateral dimension of the second positioning groove 122, so that the snap-fit base 311 can be snapped into the first positioning groove 121, reinforcing the elastic positioning component 3 and thus improving the firmness of the elastic positioning component 3.
[0049] In this embodiment, the lateral dimension of the reinforcing plate 312 of the pump body assembly is equal to the lateral dimension of the second positioning groove 122, which further enhances the structural strength of the elastic positioning component 3, avoids loosening or displacement during operation, and improves the long-term reliability of the pump body assembly.
[0050] See Figure 5 , Figure 8 , Figure 9 and Figure 10 In this embodiment, the pump body assembly, spring group 32 includes a first spring 321 and a guide ring 322. The first spring 321 is fixed on the mounting base 31. The guide ring 322 has a through hole 323. The guide rod 33 passes through the first spring 321 and the through hole 323 in sequence and is inserted into the guide hole 21. The diameter of the through hole 323 is smaller than the diameter of the first spring 321, thereby preventing the first spring 321 from twisting. This ensures the stable operation of the spring assembly 32 and extends the service life of the spring.
[0051] See Figure 5 In this embodiment, the pump body assembly, spring group 32, further includes a second spring 324. The second spring 324 is disposed at the end of the guide ring 322 away from the first spring 321, and the free length of the second spring 324 is less than the free length of the first spring 321. When the slider 2 applies a compressive force to the spring group 32, the first spring 321 is preferentially subjected to the force, while the second spring 324 provides additional support, thereby effectively preventing the spring group 32 from arching during the initial compression stage and improving the overall operational stability and reliability of the structure.
[0052] See Figure 10 In this embodiment, the pump body assembly, the slide plate 2 is also provided with two relief grooves 22. The two relief grooves 22 are symmetrically distributed on both sides of the guide hole 21. When the spring assembly 32 is in a compressed state, the end of the second spring 324 extends into the relief groove 22, avoiding interference between the spring and the slide plate 2, and improving the overall structural stability and space utilization efficiency.
[0053] See Figure 11In this embodiment of the pump body assembly, when the spring assembly 32 is in its maximum compressed state, the sum of the total length of the spring assembly 32 and the length of the guide hole 21 is greater than the length of the guide rod 33; when the spring assembly 32 is in its minimum compressed state, the total length of the spring assembly 32 is less than the length of the guide rod 33. When the spring assembly 32 is in its maximum compressed state, the sum of its total length L1 and the length L2 of the guide hole 21 is greater than the length L3 of the guide rod 33, ensuring that effective compression of the spring assembly 32 does not lead to excessive exposure of the guide rod 33; while in the minimum compressed state, the total length L1 of the spring assembly 32 is less than the length L3 of the guide rod 33, avoiding obstruction during the movement of the sliding vane 2, and improving the flexibility and reliability of the system operation.
[0054] The compressor in this embodiment includes the pump assembly described above, which improves the compressor's operational stability, noise control, and durability, making it suitable for a wider range of industrial and household applications.
[0055] The air conditioner of this embodiment includes the compressor described above, and its pump assembly has optimized the core structural performance, further improving the cooling efficiency and operational stability of the air conditioner, and providing users with a more comfortable user experience.
[0056] The cylinder 1 of this invention eliminates the traditional spring hole on the outer circumference, instead providing a sliding vane groove 11 and a positioning groove 12 on the upper surface of the cylinder 1. This avoids the problems of misalignment and tilting when drilling on a circular arc surface using traditional spring holes. The distance H1 between the two reference planes of the elastic positioning component 3 is equal to the distance H2 between the two reference planes of the cylinder 1. When it is installed in the positioning groove 12 of the cylinder 1, the upper and lower planes of the snap-fit seat 311 are flush with the upper and lower precision-machined planes of the cylinder 1, achieving centered installation of the elastic positioning component. The guide rod 33 is installed on the mounting base 31 with a verticality requirement of less than 0.1, ensuring that the guide rod 33, the sliding vane guide hole 21, and the through hole 323 are on the same central axis during pump operation, resulting in more stable pump operation. The spring assembly 32 is divided into two sections: a first spring 321 and a second spring 324. The central structural guide ring 322 has a through hole 323. During operation, the guide rod 33 passes through the through hole 323, limiting the spring's arching in the middle and preventing it from scraping against the inner wall of the cylinder spring hole, thus improving the lifespan of the compression spring and the reliability of the compressor. After assembly, the depth L2 of the vane guide hole 21 must ensure that the total length of the spring assembly 32 is L1 at maximum compression, at which point the length L3 of the guide rod 33 does not reach the bottom of the guide hole 21, i.e., L1 + L2 - L3 > 0. At minimum compression, the total length of the spring assembly 32 must satisfy L1 < L3, thus preventing the guide rod 33 from disengaging from the vane guide hole 21.
[0057] In this embodiment, the middle guide ring 322 of the spring assembly 32 can be adjusted in position along the length of the spring assembly 32 according to the structure of the slider 2. The shorter spring assembly 32 can also be set as a single spring.
[0058] In this embodiment, the guide rod 33 can be configured as a circle, square or other shape as needed.
