[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0029] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0030] See also Figures 1 to 7 As shown, according to an embodiment of the present invention, a pump body structure is provided, including a first split body 3 and a second split body 4, the first split body 3 is integrally formed, and a first chamber 1 is constructed on the first split body 3, the second split body 4 is integrally formed, and a second chamber 2 is constructed on the second split body 4, the first split body 3 and the second split body 4 are assembled and spliced ​​along the axial direction of the pump body structure to form a cylinder body of the pump body structure, and the first chamber 1 and the second chamber 2 are spliced ​​to form a compression chamber.

[0031] In this technical solution, since the cylinder body of the pump body structure of the present application is formed by axially assembling and splicing an integrally formed first split body 3 and an integrally formed second split body 4, compared with the cylinder body of the pump body structure formed by assembling an upper flange, a lower flange and a cylinder in the prior art, it has fewer parts and no radial gap, which not only makes the assembly of the cylinder body of the pump body structure simpler, but also the cylinder body of the pump body structure has no radial gap. Therefore, when the pump body compression chamber is exhausted, there is no serious radial leakage problem on the high-pressure side of the compression chamber, which helps to improve the performance of the compressor.

[0032] See also Figure 1 As shown, the first split body 3 is configured with an air intake port 22 corresponding to the first chamber 1, the second split body 4 is configured with an air exhaust port 21 corresponding to the second chamber 2, and the cylinder body of the pump body structure is configured with a vane groove connected to the compression chamber, the vane groove has a center plane extending along the axial direction of the pump body structure, and the first split body 3 is located on one side of the center plane.

[0033] In this embodiment, an exhaust valve plate is provided at the exhaust port 21, a rotatable roller 16 is installed in the compression chamber, a slidable vane 15 is installed in the vane groove, and the vane 15 cooperates with the roller 16. The process from the position of the air intake port 22 to the exhaust valve plate opening is a low-pressure process, and the process of exhausting after the exhaust valve plate opens is a high-pressure process. The roller 16 rotates 180° from the vane groove corresponding to the low-pressure process, and rotates 180° to 360° corresponding to the high-pressure process, and the center plane of the vane groove is exactly the dividing line between the low-pressure process and the high-pressure process. When the first split body 3 with the air intake port 22 is located on one side of the center plane of the vane groove, it indicates that the joint seam formed between the first split body 3 and the second split body 4 is on the low-pressure side, and the radial leakage of gas mainly occurs in the high-pressure process. When the roller 16 rotates to the high-pressure side, it has crossed the joint seam formed between the first split body 3 and the second split body 4, so it can be ensured that there is no gas leakage during exhaust. It should be noted that the joint formed between the first split body 3 and the second split body 4 is on the low-pressure side, and there is an oil seal at the joint. During the entire intake and exhaust process, there may be a slight leakage at the joint, but it can be ignored.

[0034] As a specific implementation, the first sub-body 3 is configured with a first chute 5 extending along the radial direction of the pump body structure, and the first chute 5 is connected to the first chamber 1. The second sub-body 4 is configured with a second chute 6 extending along the radial direction of the pump body structure, and the second chute 6 is connected to the second chamber 2. The first chute 5 and the second chute 6 are combined to form a vane groove, and the first chute 5 and the second chute 6 are symmetrical with respect to the center plane of the vane groove, and the first chamber 1 and the second chamber 2 are also symmetrical with respect to the center plane of the vane groove. Such a symmetrical design can facilitate the processing of the first sub-body 3 and the second sub-body 4 on the basis of ensuring that there is no gas leakage when the pump body compression chamber is exhausted.

[0035] See also Figure 1 and Figure 3 As shown, the first split body 3 includes a first cylinder portion 31 and a first flange portion 32 integrally formed on one side of the first cylinder portion 31, the first chamber 1 is constructed on the first cylinder portion 31, the second split body 4 includes a second cylinder portion 41 and a second flange portion 42 integrally formed on one side of the second cylinder portion 41, and the second chamber 2 is constructed on the second cylinder portion 41; when the first split body 3 and the second split body 4 are assembled and spliced ​​to form the cylinder body of the pump body structure, the first flange portion 32 and the second flange portion 42 are aligned and spliced, the first cylinder portion 31 and the second cylinder portion 41 are aligned and spliced, and the first flange portion 32 and the second flange portion 42 are connected by a first connecting member (not shown in the figure).

[0036] In this technical solution, for the cylinder body of the existing pump body structure formed by assembling the upper flange, the lower flange and the cylinder, the upper flange and the cylinder, and the lower flange and the cylinder are fixed by screws, so it is necessary to construct threaded holes on the wall of the cylinder for screw thread connection, which requires the wall of the cylinder to be designed to be thicker. The cylinder body of the pump body structure of the present application is assembled and spliced ​​by the first split body 3 and the second split body 4 along the axial direction, and the first flange part 32 of the first split body 3 is integrally formed on the first cylinder part 31, and the second flange part 42 of the second split body 4 is integrally formed on the second cylinder part 41, so the first split body 3 and the second split body 4 can be fixed together by connecting the first flange part 32 and the second flange part 42 through the first connecting member. In this way, the first connecting member can be avoided from the first cylinder part 31 and the second cylinder part 41, so the first cylinder part 31 and the second cylinder part 41 do not need to reserve space for the connection of the first connecting member, so that the wall of the first cylinder part 31 and the second cylinder part 41 can be designed to be thinner, and then the first chamber 1 and the second chamber 2 can be designed to be larger. That is, under the condition of the same outer dimensions, the compression chamber of the pump body structure of the present application is larger than the compression chamber of the pump body structure in the prior art, so that the material utilization rate is higher and the amount of refrigerant compressed in a single time is larger. Among them, the first connecting member can be a screw, the first flange part 32 is configured with a first threaded hole 11, the second flange part 42 is configured with a second threaded hole 12, and the first connecting member is threadedly connected in the first threaded hole 11 and the second threaded hole 12. It can be understood that the first slide groove 5 is configured on the first cylinder part 31, and the second slide groove 6 is configured on the second cylinder part 41.

[0037] See also Figure 1 and Figure 3 As shown, there are two first connecting members, the first side of the first flange portion 32 is connected to the first side of the second flange portion 42 through one of the first connecting members, and the second side of the first flange portion 32 is connected to the second side of the second flange portion 42 through another first connecting member.

[0038] In this embodiment, the two first connecting members fix the first flange part 32 and the second flange part 42 from the left and right sides of the first flange part 32 and the second flange part 42 respectively, which is equivalent to the two first connecting members fixing the first sub-body 3 and the second sub-body 4 from the left and right sides, so that the fixation between the first sub-body 3 and the second sub-body 4 is more firm, and then the splicing gap formed between the first sub-body 3 and the second sub-body 4 is smaller. Then, during the compression process, the amount of refrigerant leaked from the splicing gap formed between the first sub-body 3 and the second sub-body 4 is less. It can be understood that when the number of the first connecting members is two, the number of the first threaded holes 11 constructed on the first flange part 32 and the number of the second threaded holes 12 constructed on the second flange part 42 are also two.

[0039] See also Figure 1 and Figure 2 As shown, the first flange portion 32 is configured with a first mounting groove 7 extending along the axial direction of the pump body structure, the first mounting groove 7 passes through the first flange portion 32 and is connected to the first chamber 1, and the second flange portion 42 is configured with a second mounting groove 8 extending along the axial direction of the pump body structure, the second mounting groove 8 passes through the second flange portion 42 and is connected to the second chamber 2. When the first split body 3 and the second split body 4 are assembled and spliced ​​to form the cylinder body of the pump body structure, the first mounting groove 7 and the second mounting groove 8 are spliced ​​to form a first axial hole, and the first mounting groove 7 and the second mounting groove 8 are symmetrical with respect to the axis center of the first axial hole.

[0040] In this technical solution, the pump body structure also includes a crankshaft 17, which has an eccentric portion, namely, a roller 16. Since the crankshaft 17 has an eccentric portion, the crankshaft 17 cannot pass through the first axial hole formed by the first mounting groove 7 and the second mounting groove 8 by insertion. The crankshaft 17 can only be placed into the first mounting groove 7 or the second mounting groove 8 from the side, and the eccentric portion of the crankshaft 17 will also be placed in the first chamber 1 or the second chamber 2. After the first split body 3 and the second split body 4 are assembled and spliced, the eccentric portion of the crankshaft 17 is in the compression chamber, and the crankshaft 17 passes through the first axial hole. Because the diameter of the crankshaft 17 is basically the same as the diameter of the first axial hole, the first mounting groove 7 and the second mounting groove 8 that are spliced ​​to form the first axial hole are symmetrical relative to the axis center of the first axial hole, that is, the first mounting groove 7 and the second mounting groove 8 are of the same size to ensure that the crankshaft 17 is placed in the first mounting groove 7 or the second mounting groove 8 from the side.

[0041] See also Figure 1 As shown, the first split body 3 also includes a third flange portion 33 integrally formed on the other side of the first cylinder portion 31, and the second split body 4 also includes a fourth flange portion 43 integrally formed on the other side of the second cylinder portion 41. When the first split body 3 and the second split body 4 are assembled and spliced ​​to form the cylinder body of the pump body structure, the third flange portion 33 and the fourth flange portion 43 are aligned and spliced, and the third flange portion 33 and the fourth flange portion 43 are connected by a second connecting member (not shown in the figure).

[0042] In this embodiment, the third flange portion 33 and the fourth flange portion 43 are connected by the second connecting piece, which further makes the fixation between the first sub-body 3 and the second sub-body 4 more secure, and further makes the joint gap formed between the first sub-body 3 and the second sub-body 4 smaller. At the same time, the second connecting piece connects the third flange portion 33 and the fourth flange portion 43, which also avoids the first cylinder portion 31 and the second cylinder portion 41, and can still ensure that the compression chamber of the pump body structure of the present application is larger than the compression chamber of the pump body structure in the prior art. Among them, the second connecting piece can be a screw, the third flange portion 33 is configured with a third threaded hole 13, the fourth flange portion 43 is configured with a fourth threaded hole 14, and the second connecting piece is threadedly connected in the third threaded hole 13 and the fourth threaded hole 14.

[0043] See also Figure 1 and Figure 3 As shown, there are two second connecting members, the first side of the third flange portion 33 is connected to the first side of the fourth flange portion 43 via one of the second connecting members, and the second side of the third flange portion 33 is connected to the second side of the fourth flange portion 43 via another second connecting member.

[0044] In this technical solution, the two second connecting members fix the third flange 33 and the fourth flange 43 from the left and right sides of the third flange 33 and the fourth flange 43 respectively, which is equivalent to the two second connecting members fixing the first sub-body 3 and the second sub-body 4 from the left and right sides, thereby further making the fixation between the first sub-body 3 and the second sub-body 4 more firm, and further making the joint gap formed between the first sub-body 3 and the second sub-body 4 smaller. It can be understood that when the number of the second connecting members is two, the number of the third threaded holes 13 constructed on the third flange 33 and the number of the fourth threaded holes 14 constructed on the fourth flange 43 are also two.

[0045] It should be noted that, for the cylinder body of the existing pump body structure formed by assembling an upper flange, a lower flange and a cylinder, at least eight to ten screws are required between the upper flange and the cylinder, and between the lower flange and the cylinder for locking and fixing. However, the cylinder body of the pump body structure of the present application formed by axially assembling and splicing the first split body 3 and the second split body 4 only requires four screws for transverse locking and fixing, thereby significantly reducing the number of screws and threaded holes, which not only reduces material costs but also simplifies the processing technology.

[0046] See also Figure 1As shown, the third flange portion 33 is configured with a third mounting groove 9 extending along the axial direction of the pump body structure, the third mounting groove 9 passes through the third flange portion 33 and is connected to the first chamber 1, and the fourth flange portion 43 is configured with a fourth mounting groove 10 extending along the axial direction of the pump body structure, the fourth mounting groove 10 passes through the fourth flange portion 43 and is connected to the second chamber 2. When the first split body 3 and the second split body 4 are assembled and spliced ​​to form the cylinder body of the pump body structure, the third mounting groove 9 and the fourth mounting groove 10 are spliced ​​to form a second axial hole, and the third mounting groove 9 and the fourth mounting groove 10 are symmetrical with respect to the axis center of the second axial hole.

[0047] In this embodiment, because the crankshaft 17 has an eccentric portion, the crankshaft 17 cannot pass through the second axial hole formed by the third mounting groove 9 and the fourth mounting groove 10 by insertion. The crankshaft 17 can only be placed into the third mounting groove 9 or the fourth mounting groove 10 from the side, and the eccentric portion of the crankshaft 17 will also be placed in the first chamber 1 or the second chamber 2. After the first split body 3 and the second split body 4 are assembled and spliced, the eccentric portion of the crankshaft 17 is in the compression chamber, and the crankshaft 17 passes through the second axial hole. Because the diameter of the crankshaft 17 is basically the same as the diameter of the first axial hole, the third mounting groove 9 and the fourth mounting groove 10 that are spliced ​​to form the second axial hole are symmetrical relative to the axis center of the second axial hole, that is, the third mounting groove 9 and the fourth mounting groove 10 are of the same size to ensure that the crankshaft 17 is placed in the third mounting groove 9 or the fourth mounting groove 10 from the side.

[0048] It should be noted that the first flange portion 32 and the second flange portion 42 are aligned and assembled, which are equivalent to the upper flange 18 in the prior art, and the third flange portion 33 and the fourth flange portion 43 are aligned and assembled, which are equivalent to the lower flange 20 in the prior art. Alternatively, the first flange portion 32 and the second flange portion 42 are aligned and assembled, which are equivalent to the lower flange 20 in the prior art, and the third flange portion 33 and the fourth flange portion 43 are aligned and assembled, which are equivalent to the upper flange 18 in the prior art. The first cylinder portion 31 and the second cylinder portion 41 are aligned and assembled, which are equivalent to the cylinder 19 in the prior art.

[0049] Finally, it should be noted that the first split body 3 and the second split body 4 are both formed by integral casting, and the hollow areas on the first split body 3 and the second split body 4 are semi-finished, and then the first chamber 1, the second chamber 2, the first mounting groove 7, the second mounting groove 8, the third mounting groove 9, the fourth mounting groove 10, the first slide groove 5 and the second slide groove 6 are finely processed.
