Description

Technical Field

[0001] The invention relates to the technical field of compressor equipment, and in particular to a pump body component, a compressor and an air conditioner. Background Art

[0002] The pump structure of the existing rolling rotor compressor is shown in 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 installing vane D, an inner cavity for installing roller E and a spring hole for installing compression spring C. Roller E and crankshaft B are eccentrically arranged in the inner cavity of cylinder A. Vane D is installed in the vane groove of the cylinder. Compression spring C is fitted in the spring hole of the cylinder through tail interference fit. The head of the compression spring contacts the tail of the vane, and the vane D and roller E are tightly fitted through the spring force.

[0003] However, since there will always be errors in the position and size of the cylinder spring hole in actual processing, the spring hole cannot be completely centered in the thickness direction of the cylinder. When the offset is too large, it will cause the pump body to be unstable during operation, the vane and the roller will not fit well, the compressor will produce vane impact noise and performance will be reduced. Secondly, when the cylinder spring hole is not centered, the gap between the head of the compression spring and the tail groove of the vane causes the head and tail of the compression spring to be misaligned after installation, and the middle part of the compression spring will bend after the head and tail are misaligned. After the compression spring is bent, the arched middle part is easy to scrape the inner wall of the spring hole, causing the spring to wear and fail, thereby reducing the reliability of the compressor.

[0004] Therefore, the prior art needs to be further developed. Summary of the invention

[0005] The purpose of the present invention is to overcome the above technical deficiencies and provide a pump body assembly, a compressor and an 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 deviation will cause the pump body to run unsteadily.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] According to an embodiment of the present invention, a pump assembly is provided. Figures 3 to 11 , including a cylinder 1, a slide groove 11 for installing a slide 2, and an inner cavity for installing a roller 13 are provided on the cylinder 1, and the pump body assembly also includes: an elastic positioning assembly 3; a positioning groove 12 for installing the elastic positioning assembly 3 is also provided on the cylinder 1, and the positioning groove 12 is coaxially arranged with the slide groove 11, and the elastic positioning assembly 3 abuts against the slide 2, and is used to push the slide 2 to move along the axis in the slide groove 11 through its own elastic force, and keep the slide 2 and the roller 13 in contact. Figure 1 and Figure 2As shown, in the conventional rolling rotor compressor, the spring hole is located in the thickness direction of the cylinder, but due to processing errors, the spring hole may not be completely centered. The installation deviation of the spring will lead to the following problems: the sliding plate and the roller are not well fitted, causing the sliding plate movement trajectory to deviate; the middle part of the spring is bent or arched due to uneven force, which may scrape the inner wall of the spring hole, accelerate wear and reduce life. According to the above problems, this embodiment provides an improved pump body assembly, the elastic positioning assembly 3 is installed in the positioning groove 12, and the positioning groove 12 is coaxially arranged with the sliding plate groove 11, and the sliding plate 2 is pushed to move along the axis in the sliding plate groove 11 by the elastic force of the elastic positioning assembly 3 itself, and the sliding plate 2 is kept in contact with the roller 13. Through the elastic force provided by the elastic positioning assembly 3, the sliding plate 2 moves along the centering trajectory in the sliding plate groove 11, ensuring that the sliding plate 2 and the roller 13 in the cylinder 1 are kept in stable contact, solving the problem of sliding plate deviation caused by processing errors. The pump body assembly of this embodiment solves the technical problem that the spring hole in the cylinder thickness direction cannot be completely centered in the related art, and the resulting deviation will cause the pump body to run unsteadily.

[0029] See also Figure 3 and Figure 4 In the pump assembly of this embodiment, the two sides of the elastic positioning assembly 3 are aligned with the two side reference planes of the cylinder 1, and the connection between the elastic positioning assembly 3 and the slide 2 is located on the central axis of the slide 2. The two side reference planes of the elastic positioning assembly 3 and the two side reference planes of the cylinder 1 are designed to be completely aligned, providing an accurate reference for the movement of the slide 2. In other words, refer to Figure 4 From the perspective of the cylinder 1, the distance H1 between the two side reference planes of the elastic positioning component 3 is equal to the distance H2 between the two side reference planes of the cylinder 1. The two side reference planes of the cylinder 1 are completed by a fine machining process with high precision and flatness, ensuring the accuracy of the installation position of the elastic positioning component 3. The vane groove 11 and the positioning groove 12 are used to install the vane 2 and the elastic positioning component 3, respectively. The connection between the elastic positioning component 3 and the vane 2 is located on the central axis of the vane 2. The shape and size of the positioning groove 12 match the elastic positioning component 3. The elastic positioning component 3 will not deviate in the thickness direction of the cylinder 1 (that is, the two side reference planes of the cylinder 1), thereby ensuring that the force center lines of the elastic positioning component 3 and the vane 2 are always consistent, thereby improving the smoothness of the pump body operation, reducing noise and improving the performance of the compressor.

[0030] See also Figure 5In the pump assembly of this embodiment, the elastic positioning assembly 3 further includes a mounting seat 31 and an elastic member disposed on the mounting seat 31. The mounting seat 31 is clamped in the positioning groove 12. The elastic member is vertically disposed on the mounting seat 31 and is coaxial with the central axis of the slide 2. The elastic member is vertically disposed on the mounting seat 31, providing a reliable elastic force transmission path, further enhancing the stability of the slide 2 moving in the slide groove 11. This clamping method simplifies the installation process and improves the assembly efficiency and structural reliability of the pump assembly.

[0031] See also Figure 5 In the pump body assembly of this embodiment, the elastic positioning assembly 3 also includes a guide rod 33, which is vertically fixed on the mounting seat 31, and the elastic member is sleeved on the guide rod 33; the guide rod 33 is coaxial with the central axis of the slide 2, further accurately determining the direction of action of the elastic member on the slide 2.

[0032] See also Figure 5 In the pump body assembly of this embodiment, the cross-section of the positioning groove 12 is a rectangle, and an opening connected to the slide groove 11 is opened on the side wall where one short side of the rectangle is located; the mounting seat 31 is clamped on the side wall where the other short side of the rectangle is located, and after clamping, the guide rod 33 points to the slide groove 11, so that the guide rod 33 and the elastic member are accurately abutted against the slide 2.

[0033] See also Figure 5 In the pump assembly of this embodiment, the elastic member is a spring group 32, which is sleeved on a guide rod 33, which is arranged along the central axis of the mounting seat 31, and the central axis of the mounting seat 31 coincides with the central axis of the slide 2. The arrangement of the guide rod 33 ensures the axial stability of the spring group 32, avoids the spring from being offset or unevenly stressed, improves the performance of the elastic positioning assembly 3, and at the same time, the central axis of the mounting seat 31 coincides with the central axis of the slide 2, further enhancing the accuracy of the movement of the slide 2.

[0034] See also Figure 5 and Fig.10 In the pump body assembly of this embodiment, the slide 2 is provided with a guide hole 21. When the slide 2 moves in the slide groove 11, the guide hole 21 slides along the guide rod 33, so that the guide rod 33 guides and limits the movement of the slide 2, which significantly reduces the deviation or vibration problem of the slide 2 during operation.

[0035] See also Figure 6 and Figure 7In the pump body assembly of this embodiment, the mounting seat 31 includes a snap-fit ​​seat 311 and a reinforcement plate 312, the snap-fit ​​seat 311 and the reinforcement plate 312 are fitted and connected, the positioning groove 12 includes a first positioning groove 121 and a second positioning groove 122, the snap-fit ​​seat 311 is located in the first positioning groove 121, the reinforcement plate 312 and the spring group 32 are both located in the second positioning groove 122, the guide rod 33 is fixed on the reinforcement plate 312, the lateral dimension of the first positioning groove 121 is equal to the lateral dimension of the snap-fit ​​seat 311, and the lateral dimension of the first positioning groove 121 is larger than the lateral dimension of the second positioning groove 122, so that the snap-fit ​​seat 311 can be snapped in the first positioning groove 121, reinforcing the elastic positioning assembly 3, thereby improving the firmness of the elastic positioning assembly 3.

[0036] In the pump body assembly of this embodiment, the lateral dimension of the reinforcement plate 312 is equal to the lateral dimension of the second positioning groove 122, which further enhances the structural strength of the elastic positioning assembly 3, avoids loosening or displacement during operation, and improves the long-term reliability of the pump body assembly.

[0037] See also Figure 5 , Figure 8 , Fig. 9 and Fig.10 In the pump assembly of this embodiment, the spring group 32 includes a first spring 321 and a guide ring 322. The first spring 321 is fixed on the mounting seat 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 being twisted. Ensure the stable operation of the spring group 32 and extend the service life of the spring.

[0038] See also Figure 5 In the pump assembly of this embodiment, the spring group 32 further includes a second spring 324, which is arranged at one end of the guide ring 322 away from the first spring 321, and the free length of the second spring 324 is smaller than the free length of the first spring 321. When the slide 2 applies a compressive force to the spring group 32, the first spring 321 is preferentially acted upon, while the second spring 324 provides additional support, thereby effectively preventing the spring group 32 from arching at the initial stage of compression, and improving the operational stability and reliability of the overall structure.

[0039] See also Fig.10 In the pump body assembly of this embodiment, the slide 2 is also provided with two clearance grooves 22, and the two clearance grooves 22 are symmetrically distributed on both sides of the guide hole 21. When the spring group 32 is in a compressed state, the end of the second spring 324 extends into the clearance groove 22, avoiding interference between the spring and the slide 2, thereby improving the running stability and space utilization efficiency of the overall structure.

[0040] See also Fig.11In the pump assembly of this embodiment, when the spring group 32 is in the maximum compression state, the sum of the total length of the spring group 32 and the length of the guide hole 21 is greater than the length of the guide rod 33; when the spring group 32 is in the minimum compression state, the total length of the spring group 32 is less than the length of the guide rod 33. When the spring group 32 is in the maximum compression 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 the effective compression of the spring group 32 will not lead to excessive exposure of the guide rod 33; and in the minimum compression state, the total length L1 of the spring group 32 is less than the length L3 of the guide rod 33, avoiding obstacles in the movement of the slide 2, and improving the flexibility and reliability of the system operation. The compressor of this embodiment includes the pump body assembly as described above, which improves the running stability, noise control effect and durability of the compressor and is suitable for a wider range of industrial and household scenarios.

[0041] The air conditioner of this embodiment includes the compressor as described above, and its pump body assembly optimizes the core structural performance, further improves the cooling efficiency and operating stability of the air conditioner, and provides users with a more comfortable use experience.

[0042] The cylinder 1 of the present invention eliminates the traditional spring hole set on the outer circle, and instead sets a slide groove 11 and a positioning groove 12 on the upper surface of the cylinder 1, which can avoid the problem of the traditional spring hole being not centered or tilted during the circular arc surface drilling process. The distance H1 between the two sides of the reference plane of the elastic positioning component 3 is equal to the distance H2 between the two sides of the reference plane of the cylinder 1. When it is installed in the positioning groove 12 of the cylinder 1, the upper and lower planes of the clamping seat 311 are flush with the upper and lower finishing planes of the cylinder 1, realizing the centered installation of the elastic positioning component. The guide rod 33 is installed on the mounting seat 31 with a verticality requirement of less than 0.1, ensuring that the guide rod 33, the slide guide hole 21, and the through hole 323 are on the same central axis when the pump body is running, and the pump body runs more smoothly. The spring group 32 is divided into two sections, the first spring 321 and the second spring 324. The middle structure guide ring 322 has a through hole 323. During operation, the guide rod 33 passes through the through hole 323. The guide rod 33 limits the spring from arching in the middle to avoid arching and scraping the inner wall of the cylinder spring hole, thereby improving the service life of the compression spring and the reliability of the compressor. After assembly, the depth L2 of the slide guide hole 21 must ensure that the total length of the spring group 32 is L1 when it is compressed to the maximum, and the length L3 of the guide rod 33 does not reach the bottom of the guide hole 21, that is, L1+L2-L3>0; when the spring group 32 is compressed to the minimum, its total length needs to meet L1<L3, so that the guide rod 33 does not fall out of the slide guide hole 21.

[0043] In this embodiment, the middle guide ring 322 of the spring group 32 can adjust its position on the length of the spring group 32 according to the structure of the slide 2, and the spring group 32 with a shorter length can also be set as a section of spring.

[0044] In this embodiment, the guide rod 33 can be configured to be circular, square or other shapes as required.
