Description

Technical Field

[0001] This application relates to the field of compressor technology, and in particular to a compressor and a vehicle. Background Technology

[0002] In automotive rotary compressors, the compression components are typically immersed in an oil sump to ensure reliable lubrication. However, this oil sump often contains impurities such as metal shavings and dust particles. If these impurities enter the compressor pump body, they can cause severe wear on the mechanical parts, affecting the compressor's performance and lifespan. To prevent impurities from entering the pump body, a filter screen is usually installed at the oil inlet. This filter screen generally consists of a plastic retainer and a metal mesh, secured by an interference fit between the plastic retainer and the oil inlet. However, under the high temperature and high vibration operating environment of the compression components, the interference fit between the plastic retainer and the oil inlet can easily fail, causing the filter screen to loosen and fall off. This prevents the filter screen from effectively blocking impurities from entering the pump body, thus affecting the compressor's performance and lifespan. Utility Model Content

[0047] The following is for reference. Figures 1-4 This application describes a compressor 1000 and a vehicle according to embodiments thereof.

[0048] like Figure 1 As shown, according to the first aspect embodiment of the present application, the compressor 1000 includes: a housing 400, a compression assembly, and a filter assembly 100.

[0049] The compression assembly is housed within the housing 400 and includes a crankshaft 200 and a first bearing 300 disposed at one end of the crankshaft 200. The first bearing 300 has an oil inlet. The filter assembly 100 includes a filter screen 1 and a connector 2. The filter screen 1 is cylindrical, and the connector 2 is disposed at one end of the filter screen 1. The connector 2 has a threaded portion 21 formed on it to be fixed to the oil inlet through the threaded portion 21. The connector 2 is made of metal.

[0050] Specifically, the compression assembly can be housed within the housing 400, which can accommodate, fix, and protect the compression assembly and the filter assembly 100, etc. The compression assembly includes a crankshaft 200, which is a power transmission component that transmits the rotational power of the motor in the compressor 1000 to the piston, enabling the piston to compress gas. A first bearing 300 is provided at one end of the crankshaft 200, which supports the crankshaft 200 and reduces friction and wear during rotation, thus improving the smoothness of the compressor 1000's operation. The first bearing 300 is provided with an oil inlet, through which oil can enter the first bearing 300 to lubricate and dissipate heat from the compression assembly 300. The filter screen 1 in the filter assembly 100 can have a dense mesh structure to intercept impurities in the oil, such as particles, dust, and metal shavings, thereby achieving a filtering effect and improving the cleanliness of the oil. The filter screen 1 is cylindrical in shape. This cylindrical structure allows the filter screen 1 to fully expand, increasing the filtration area and improving the uniformity of fluid distribution as it passes through the filter screen 1, thereby enhancing filtration efficiency and effectiveness. The filter screen 1 can be made of high-strength, corrosion-resistant metal or synthetic fiber materials, which possess excellent filtration performance and durability, ensuring stable filtration performance in harsh working environments (such as high-temperature and high-vibration environments). The connector 2 in the filter screen assembly 100 can be located at one axial end of the filter screen 1 and is adapted to be fixed to the oil inlet of the first bearing 300, thus securing the filter screen 1 to the oil inlet. The connector 2 has a threaded portion 21 that mates with the threaded structure of the oil inlet. By rotating the connector 2, the connection between the connector 2 and the oil inlet can be secured, making installation simple, quick, and stable. The connector 2 is made of metal, which gives it excellent properties such as high strength, corrosion resistance and high temperature resistance. This ensures that the connector 2 maintains good working performance in harsh working environments. At the same time, the metal threaded part 21 can apply a relatively large pre-tightening force to prevent loosening, which can improve the stability of the connector 2 when it is fixed to the oil inlet or outlet, thereby ensuring the reliability of the filter screen 1 in the oil inlet.

[0051] It should be noted that the refrigerant of the compressor 1000 in this application may be, but is not limited to, carbon dioxide. The refrigerant of the compressor 1000 may also be other refrigerants, such as hydrofluorocarbon refrigerants, natural working fluids such as ammonia and water, and other types of refrigerants.

[0052] According to the compressor 1000 of this application, its filter assembly 100 can be fixed to the oil inlet of the first bearing 300 through the threaded portion 21 on the metal connector 2. This can enhance the installation stability of the connector 2, optimize the anti-loosening performance, and ensure the working stability in high temperature and high vibration working environments. This can ensure the reliable filtration effect of the filter 1 at the oil inlet, ensure the cleanliness of the oil, and thus help improve the overall performance, life and safety of the compression assembly and the compressor 1000.

[0053] Furthermore, in some specific embodiments of this application, the housing 400 includes an outer shell 402 and a bracket 404, the outer shell 402 and the bracket 404 defining a receiving cavity 400a, the compression assembly being disposed within the receiving cavity 400a, and one end of the crankshaft 200 passing through the bracket 404. The bracket 404 and the outer shell 402 can be arranged sequentially in the axial direction. The bracket 404 can be used to support and fix components such as the crankshaft 200, thereby improving the overall stability and reliability of the crankshaft 200 and the compression assembly.

[0054] In some other specific embodiments of this application, the compression assembly further includes: a second bearing 600 and a cylinder 500. The cylinder 500 has a cylinder partition 506, which separates the cylinders 500 and defines a first cylinder 502 and a second cylinder 504. The first bearing 300 is located on the side of the second cylinder 504 away from the first cylinder 502, and the second bearing 600 is located on the side of the first cylinder 502 away from the second cylinder 504. The second bearing 600, the cylinder 500, and the first bearing 300 are all sleeved on the outer periphery of the crankshaft 200 and are arranged sequentially along the axial direction of the crankshaft 200. The second bearing 600 and the first bearing 300 can support the crankshaft 200 at different positions on the crankshaft 200 and reduce friction and wear during rotation, thereby improving the smooth operation of the compressor 1000. A piston can be installed inside the cylinder 500. The piston is connected to the crankshaft 200. The crankshaft 200 transmits the rotational power of the motor in the compressor 1000 to the piston, and drives the piston to reciprocate within the cylinder 500, thereby ensuring the compression operation of the compressor 1000.

[0055] like Figure 3 and Figure 4 As shown, according to some embodiments of this application, the filter assembly 100 further includes a retainer 3, which is connected to the connector 2, and the filter 1 is embedded in the retainer 3.

[0056] Specifically, the retainer 3 can have an embedding space, in which the filter screen 1 can be embedded and fit against the wall of the embedding space. The retainer 3 supports the filter screen 1, ensuring that the filter screen 1 maintains a stable cylindrical shape and structure. This prevents the filter screen 1 from deforming or being damaged under fluid pressure, guaranteeing the consistency and reliability of the filter screen 1's filtration effect. Furthermore, the same axial end of the retainer 3 and the filter screen 1 can be connected to the connector 2, thus achieving the connection between the retainer 3, the filter screen 1, and the connector 2. The method of embedding the filter screen 1 in the retainer 3 and connecting it to the connector 2 enhances the stability and durability of the filter screen 1.

[0057] like Figure 2 and Figure 4 As shown, according to some embodiments of this application, the end of the connector 2 is provided with a connecting flange 22, which is used to fix and limit the retainer 3.

[0058] Specifically, the connecting flange 22 can be disposed at the end of the connector 2 axially close to the retainer 3. The connecting flange 22 can be used for the installation and positioning of the retainer 3 and the filter screen 1, and for fixing and limiting the retainer 3 and the filter screen 1. Exemplarily, the connecting flange 22 can be configured to extend radially in the connector 2, and the connecting flange 22 defines a mounting hole at the end radially away from the connector 2. A radially extending groove can be formed on the retainer 3, with the mounting hole passing through the retainer 3 at one axial end, and the connecting flange 22 extending into the groove of the retainer 3 to limit the movement of the retainer 3 axially and radially, thereby achieving a good connection and limiting between the retainer 3 and the filter screen 1 and the connector 2. Through the fixing and limiting function of the connecting flange 22, the connection strength and stability between the retainer 3 and the filter screen 1 and the connector 2 can be improved, preventing the retainer 3 from moving or falling off under fluid pressure, and effectively improving the working reliability of the retainer 3 and the filter screen 1.

[0059] like Figures 2-4 As shown, according to some embodiments of this application, the retainer 3 is constructed of plastic, and the filter 1, the connector 2 and the retainer 3 are integrally injection molded.

[0060] Specifically, the retainer 3 can be constructed as a plastic part, while the filter screen 1 and the connector 2 can be constructed as metal parts. The filter screen 1, connector 2 and retainer 3 are integrally injection molded to form an integrated structure. In this way, on the one hand, the overall structure of the filter screen assembly 100 is stable, which can improve the overall impact and vibration resistance of the filter screen assembly 100 and ensure the stable operation of the filter screen assembly 100 in harsh working environments. On the other hand, by integrally injection molding the filter screen 1, connector 2 and retainer 3, the production process of the filter screen assembly 100 can also be simplified and the production efficiency can be improved.

[0061] Furthermore, in some specific embodiments of this application, the cage 3 is constructed of polypropylene, polyethylene, or nylon material. Polypropylene, polyethylene, and nylon materials have advantages such as high strength, strong corrosion resistance, good wear resistance, and low cost. By constructing the cage 3 as polypropylene, polyethylene, or nylon material, the cage 3 can have good working performance and durability, and save production costs.

[0062] like Figure 3 and Figure 4 As shown, according to some embodiments of this application, the retainer 3 has a plurality of support arms 31 that extend axially and are spaced apart in the circumferential direction, defining a filter channel 3a in communication with the filter screen 1.

[0063] Specifically, the retainer 3 may have multiple support arms 31 spaced apart in the circumferential direction. These support arms 31 extend axially and can work together to support and limit the filter screen 1, maintaining its cylindrical shape and structure to ensure its full deployment. The multiple support arms 31 define a filtration channel 3a, which is connected to the filter screen 1. The filtration channel 3a provides a passage for fluid to flow to the filter screen 1 for filtration, thereby removing impurities and achieving fluid cleanliness.

[0064] It is understandable that during the process of fluid passing through the filter assembly 100, the fluid can first flow into the filter channel 3a defined by multiple support arms 31, and flow along the axial direction of the support arms 31 in the filter channel 3a, and be evenly distributed throughout the entire filter channel 3a. The fluid in each region of the filter channel 3a can flow to the corresponding filter screen 1 region that is radially opposite to the filter channel 3a, thereby achieving uniform distribution of fluid on the filter screen 1 and uniform passage through the filter screen 1. After passing through the filter screen 1, the fluid can flow out from the space between multiple adjacent support arms 31, thereby completing the good filtration of the fluid by the filter assembly 100.

[0065] like Figure 2 and Figure 3 As shown, according to some embodiments of this application, the connector 2 has an inner hole 23, which communicates with the filter channel 3a.

[0066] Specifically, the inner hole 23 of the connector 2 can be configured to extend axially and penetrate the connector 2. One end of the inner hole 23 can communicate with the filter channel 3a, and the other end of the inner hole 23 is open and forms an inlet to provide a path for fluid to enter the filter assembly 100. The shape and size of the inner hole 23 can be set according to the size of the oil inlet and outlet and the properties of the fluid. For example, the inner hole 23 can be set as circular, elliptical, or other shapes to adapt to different fluid flow requirements. Simultaneously, the size of the inner hole 23 can be adjusted according to the fluid flow rate and pressure to ensure smooth fluid passage. In this embodiment, the overall process of fluid passing through the filter assembly 100 is as follows: the fluid enters the inner hole 23 through the inlet; after flowing through the inner hole 23, the fluid flows into the filter channel 3a from the end of the inner hole 23 near the filter channel 3a and flows to the filter screen 1 for filtration. The clean fluid filtered by the filter screen 1 then flows out of the filter assembly 100 from the space between adjacent support arms 31 to complete the filtration process.

[0067] like Figure 4 As shown, according to some embodiments of this application, the inner hole 23 includes a first hole segment 23a and a second hole segment 23b. The first hole segment 23a is connected to the filter screen 1 and the retainer 3, and the second hole segment 23b is constructed as an internal hexagonal hole.

[0068] Specifically, the inner hole 23 can be composed of a first hole segment 23a and a second hole segment 23b arranged sequentially along the axial direction. The first hole segment 23a is connected to the filter screen 1 and the retainer 3, enabling the inner hole 23 to communicate with the filter channel 3a and the filter screen 1. The second hole segment 23b communicates with the first hole segment 23a, and is located at the end of the first hole segment 23a that is axially away from the retainer 3 and the filter screen 1. The second hole segment 23b is constructed as an internal hexagonal hole, meaning it is located inside the connector 2. The axial projection of the second hole segment 23b is hexagonal. This internal hexagonal hole allows the connector 2 to be installed and disassembled using a special tool such as an internal hex wrench, applying torque to improve the installation and maintenance efficiency and convenience of the filter assembly 100. Furthermore, since the internal hexagonal hole is located at the end of the first hole segment 23a that is axially away from the retainer 3 and the filter screen 1, that is, the internal hexagonal hole is located at the end of the connector 2 that is axially away from the retainer 3 and the filter screen 1, the retainer 3 and the filter screen 1 will not be interfered with during the operation of the internal hexagonal hole using tools, thereby protecting the integrity of the retainer 3 and the filter screen 1.

[0069] like Figure 4 As shown, according to some embodiments of this application, the connector 2 has an inner wall 2a and an outer wall 2b, and a threaded portion 21 is formed on the outer wall 2b and is correspondingly formed as an external thread.

[0070] Specifically, the connector 2 is a hollow tubular structure with an inner wall 2a and an outer wall 2b. The inner wall 2a helps to define the channel through which fluid passes through the connector 2, and the outer wall 2b is the outer circumferential surface of the connector 2. In this embodiment, the threaded portion 21 can be formed on the outer wall 2b of the connector 2, and correspondingly formed as an external thread. The oil inlet of the first bearing 300 can be formed with an internal thread to achieve a threaded engagement with the external thread of the connector 2. By fixing the connector 2 to the oil inlet through the threaded engagement, good stability and anti-loosening performance of the connector 2 at the oil inlet can be ensured, thereby ensuring the reliable operation of the filter screen 1 under high temperature and high vibration environments.

[0071] like Figure 4 As shown, according to some embodiments of this application, the connecting flange 22 of the connector 2 is formed on the inner wall 2a.

[0072] Specifically, the connecting flange 22 of the connector 2 is formed on the inner wall 2a. The connecting flange 22 can extend radially close to the central axis of the connector 2. One end of the retainer 3 is connected to the side of the connecting flange 22 that is radially close to the central axis of the connector 2. The threaded portion 21 is formed on the outer wall 2b of the connector 2. Thus, the threaded portion 21 and the connecting flange 22 are located on different sides of the connector 2 in the radial direction. This can protect the limiting connection between the connecting flange 22 and the retainer 3 from interference with the threaded portion 21. It can ensure that the connector 2, the retainer 3 and the filter screen 1 as a whole have good installation stability and working reliability. At the same time, it is also conducive to improving the structural compactness of the connector 2, the retainer 3 and the filter screen 1, which helps to optimize space utilization, provide more channels and space for fluid, and enhance filtration efficiency and effect.

[0073] like Figures 1-4 As shown, the vehicle according to the second aspect of this application includes: the compressor 1000 as described in any of the above embodiments, and the resulting technical effects are the same as those in the above embodiments, which will not be repeated here.
