Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a compressor, an air conditioning system, and a vehicle. Background Technology

[0002] In a traditional compressor structure, the compressor has a main shaft and an eccentric wheel. The main shaft has a crank pin and a limiting cavity, while the eccentric wheel has a crank pin hole and a limiting pin hole. A limiting pin is pressed into the limiting pin hole, and the crank pin hole on the eccentric wheel fits onto the crank pin on the main shaft. Simultaneously, the limiting pin movably passes through the limiting cavity on the main shaft, allowing restricted movement within the cavity to limit the rotation angle of the eccentric wheel. Furthermore, in related technologies, the eccentric wheel is mounted on a moving plate base. Due to a limiting angle adjustment mechanism between the eccentric wheel and the main shaft, the moving plate can also rotate relative to the main shaft within a fixed angle, and has a retraction mechanism relative to the stationary plate (i.e., the moving and stationary plate teeth do not mesh, and a closed compression chamber is not formed). When the compressor starts at low speed, the limiting pin collidees within the limiting cavity, generating noise. Simultaneously, the low rotational speed of the moving plate means there is insufficient centrifugal force to engage with the stationary plate, compromising starting stability. Utility Model Content

[0003] The purpose of this utility model is to provide a compressor, an air conditioning system, and a vehicle to solve the problem of noise generated after the limiting pin collides in the limiting cavity in the prior art.

[0004] On one hand, this utility model provides a compressor, which includes: a housing having a receiving cavity; a crankshaft including a main shaft and a crank pin eccentrically disposed on the main shaft, the main shaft being rotatably disposed within the receiving cavity, the main shaft having a limiting cavity; an eccentric wheel having a crank pin hole and a limiting hole, the crank pin being disposed in the crank pin hole; a limiting pin assembly including a limiting pin body and an elastic post, the limiting pin body passing through the elastic post and being eccentrically disposed with the elastic post, the elastic post being disposed within the limiting cavity, the limiting pin body being disposed in the limiting hole; and a compression assembly connected to the side of the eccentric wheel opposite to the main shaft, the compression assembly having a compression cavity for compressing refrigerant.

[0005] As an optional technical solution for the compressor, the limiting pin body and the elastic column are an integral structure formed by injection molding.

[0006] As an optional technical solution for the compressor, the elastic column is made of rubber or polyurethane.

[0007] As an optional technical solution for the compressor, the compression assembly includes a moving disc and a stationary disc. The moving disc and the eccentric wheel are connected to the side opposite to the main shaft. The stationary disc can engage with the moving disc to form the compression chamber. When the stationary disc is not engaged with the moving disc, the limiting pin body is located in a first position. When the stationary disc engages with the moving disc, the limiting pin body is located in a second position. The first position is offset relative to the second position toward the rotation direction of the moving disc.

[0008] As an optional technical solution for the compressor, the moving disc has a mounting hole on the side facing the main shaft, the eccentric wheel is located in the mounting hole and connected to the inner wall of the mounting hole.

[0009] As an optional technical solution for the compressor, the compression assembly further includes an intermediate body located within the receiving cavity. One end of the intermediate body is connected to the inner wall of the outer casing, and the other end of the intermediate body abuts against the stationary disc. The main shaft passes through the intermediate body and is rotatably connected to it. The moving disc is located on the side of the intermediate body facing the stationary disc.

[0010] As an optional technical solution for the compressor, the compressor also includes a drive motor located inside the receiving cavity. The drive motor is driven and connected to the main shaft so that the main shaft drives the eccentric wheel to rotate.

[0011] As an optional technical solution for the compressor, the compressor also includes a rear cover, which is connected to the compression assembly.

[0012] On the other hand, this utility model provides an air conditioning system, including the compressor in any of the above-mentioned solutions.

[0013] On the other hand, this utility model provides a vehicle that includes the air conditioning system of any of the above-mentioned solutions.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention provides a compressor comprising a housing, a crankshaft, an eccentric wheel, a limiting pin assembly, and a compression assembly. The housing has a receiving cavity; the crankshaft includes a main shaft and a crank pin; the eccentric wheel has a crank pin hole and a limiting hole; the limiting pin assembly includes a limiting pin body and an elastic post. In this compressor, the elastic post is positioned within the limiting cavity, and the limiting pin body is positioned within the limiting hole. When the stationary and moving discs mesh, the limiting pin body is pressed back to the center position of the limiting cavity, and simultaneously, the elastic post is compressed, applying a preload force in the direction of rotation to the eccentric wheel and the moving disc. Through this configuration, when the compressor starts at low speed, the elastic post within the limiting cavity effectively prevents direct collision between the limiting cavity and the limiting pin body, thus avoiding starting noise. The compressor of this invention, by incorporating the elastic post, effectively solves the problem of noise generated by the limiting pin body colliding within the limiting cavity in existing technologies.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] like Figures 1 to 6As shown, this embodiment provides a compressor, which includes a housing 1, a crankshaft 2, an eccentric wheel 3, a limiting pin assembly 4, and a compression assembly 5. The housing 1 has a receiving cavity 11; the crankshaft 2 includes a main shaft 21 and a crank pin 22 eccentrically mounted on the main shaft 21, the main shaft 21 being rotatably disposed within the receiving cavity 11, and the main shaft 21 having a limiting cavity 211; the eccentric wheel 3 has a crank pin hole 31 and a limiting hole 32, the crank pin 22 being disposed in the crank pin hole 31; the limiting pin assembly 4 includes a limiting pin body 41 and an elastic post 42, the limiting pin body 41 passing through the elastic post 42 and being eccentrically mounted to the elastic post 42, the elastic post 42 being disposed within the limiting cavity 211, and the limiting pin body 41 being disposed in the limiting hole 32; the compression assembly 5 is connected to the side of the eccentric wheel 3 opposite to the main shaft 21, and the compression assembly 5 has a compression cavity 53 for compressing refrigerant.

[0035] The compressor of this invention features an elastic column 42 positioned within the limiting cavity 211, with the limiting pin body 41 positioned within the limiting hole 32. When the stationary disc 52 and the moving disc 51 engage, the limiting pin body 41 is pressed back to the center position of the limiting cavity 211, while the elastic column 42 is also compressed, applying a preload force in the direction of rotation to the eccentric wheel 3 and the moving disc 51. Through this configuration, when the compressor starts at low speed, the presence of the elastic column 42 within the limiting cavity 211 effectively prevents direct collision between the limiting cavity 211 and the limiting pin body 41, thus avoiding starting noise. The compressor of this invention, by incorporating the elastic column 42, effectively solves the problem of noise generated by the limiting pin body 41 colliding within the limiting cavity 211 in the prior art.

[0036] In this embodiment, the limiting pin body 41 and the elastic column 42 are integrally injection molded structures. This arrangement can improve the connection strength between the limiting pin body 41 and the elastic column 42, while reducing production costs.

[0037] In some embodiments, the material of the elastic column 42 includes, but is not limited to, rubber or polyurethane. Rubber has high elasticity and good water resistance; polyurethane has high wear resistance and elasticity, and excellent oil resistance.

[0038] In this embodiment, the compression assembly 5 includes a moving disk 51 and a stationary disk 52. The moving disk 51 is connected to the side of the eccentric wheel 3 opposite to the main shaft 21, and the stationary disk 52 can engage with the moving disk 51 to form a compression chamber 53. Figure 5 As shown, when the stationary disc 52 and the moving disc 51 are not engaged, the limiting pin body 41 is in the first position, where O1 is the center of the main shaft, O 21 O2 is the center of the eccentric wheel 3 when the stationary disk 52 and the moving disk 51 are not engaged; O3 is the center of the crank pin in the theoretical state when the stationary disk 52 and the moving disk 51 are engaged. Figure 6As shown, when the stationary disc 52 and the moving disc 51 are engaged, the limiting pin body 41 is in the second position. It can be seen that when the stationary disc 52 and the moving disc 51 are not engaged, the first position is offset relative to the second position towards the rotation direction of the moving disc 51. With this configuration, when the stationary disc 52 and the moving disc 51 are engaged, interference occurs between the toothed walls of the stationary disc 52 and the moving disc 51. This causes the moving disc 51 to move the eccentric wheel 3 and the limiting pin body 41, simultaneously pressing the elastic column 42. The pressed elastic column 42 continuously applies a preload force to the limiting pin body 41, the eccentric wheel 3, and the moving disc 51 in the engagement direction of the moving disc 51. This ensures that the moving disc 51 remains tightly fitted against the toothed wall of the stationary disc 52, maintaining engagement and guaranteeing stability during low-speed starting.

[0039] In some embodiments, the movable disk 51 has a mounting hole on the side facing the main shaft 21, wherein the eccentric wheel 3 is located inside the mounting hole and connected to the inner wall of the mounting hole. This facilitates the eccentric wheel 3 driving the movable disk 51 to rotate.

[0040] Furthermore, the compression assembly 5 also includes an intermediate body 54. The intermediate body 54 is located inside the receiving cavity 11, one end of the intermediate body 54 is connected to the inner wall of the outer shell 1, and the other end of the intermediate body 54 abuts against the stationary disk 52. Meanwhile, the main shaft 21 passes through the intermediate body 54 and is rotatably connected to the intermediate body 54 to facilitate the rotation of the main shaft 21. The moving disk 51 is located on the side of the intermediate body 54 facing the stationary disk 52.

[0041] In some embodiments, the compressor further includes a drive motor 6. The drive motor 6 is located within the receiving cavity 11 and is drivenly connected to the main shaft 21, so that the drive motor 6 can drive the eccentric wheel 3 to rotate via the main shaft 21.

[0042] In this embodiment, the compressor also includes a rear cover 7. This facilitates the connection between the rear cover 7 and the compression assembly 5.

[0043] This embodiment also provides an air conditioning system, including the compressor described above. In this air conditioning system, the elastic column 42 is positioned within the limiting cavity 211, and the limiting pin body 41 is positioned within the limiting hole 32. When the stationary disc 52 and the moving disc 51 engage, the limiting pin body 41 is pressed back to the center position of the limiting cavity 211, and simultaneously, the elastic column 42 is compressed, applying a preload force in the direction of rotation to the eccentric wheel 3 and the moving disc 51. Through this configuration, when the compressor starts at low speed, the presence of the elastic column 42 within the limiting cavity 211 effectively prevents direct collision between the limiting cavity 211 and the limiting pin body 41, thus avoiding starting noise. The air conditioning system of this invention, by incorporating the elastic column 42, effectively solves the problem of noise generated after the limiting pin body 41 collides within the limiting cavity 211 in the prior art.

[0044] This embodiment also provides a vehicle including the air conditioning system described above. The vehicle of this embodiment incorporates all the advantages of the aforementioned air conditioning system, which will not be elaborated further here.

[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
