DETAILED DESCRIPTION

[0055] The object of the present invention is to provide a compressor housing, a compressor assembly and a manufacturing method, which are used to reduce the weight of the compressor housing, reduce transportation and manufacturing costs, improve production efficiency through injection molding, and reduce pollution.

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0057] See also Figures 1-12The present invention provides a compressor housing 100, which includes a compressor housing and a motor and a pump body arranged in the compressor housing. The compressor housing includes a compressor upper housing 110, a compressor main housing 120 and a compressor lower housing 130. The compressor upper housing 110, the compressor main housing 120 and the compressor lower housing 130 are made of plastic. The compressor upper housing 110 is connected to the top end of the compressor main housing 120, and the compressor lower housing 130 is connected to the bottom end of the compressor main housing 120.

[0058] In this embodiment, the compressor housing is made of plastic, which can effectively reduce the weight of the compressor housing, reduce transportation costs and material costs, and facilitate processing. The injection molding process can effectively improve processing efficiency, increase production capacity, and reduce manufacturing costs. Moreover, the plastic itself is corrosion-resistant, and after molding, there is no need to perform anti-corrosion processes such as painting on the outside. Therefore, the process is simpler and avoids painting to pollute the environment.

[0059] Preferably, the compressor housing is free of friction compared to internal components such as the pump body, thus requiring less demanding wear resistance. Furthermore, the compressor housing has lower thermal deformation requirements, allowing for a wider range of materials. Furthermore, the compressor housing requires lower machining precision, resulting in lower processing costs. Therefore, the compressor housing can be injection molded from materials such as glass fiber reinforced nylon, carbon fiber composites, PEEK, or BMC, resulting in higher mechanical strength, as well as resistance to oxidation, high temperatures, and corrosion.

[0060] It should be noted that the compressor main housing 120 is the cylindrical portion of the compressor housing.

[0061] In a specific embodiment, the compressor housing includes at least one welding position and multiple prefabricated structures welded through the welding positions, and the prefabricated structures are injection molded separately; and the multiple prefabricated structures include: a first prefabricated structure having a compressor upper housing 110, and a second prefabricated structure having a compressor lower housing 130, the first prefabricated structure and the second prefabricated structure are injection molded separately, and then welded to each other or welded through other prefabricated structures.

[0062] It should be noted that by splitting the compressor housing into multiple prefabricated structures, modular production is achieved, the complexity of the injection mold is reduced, and manufacturing flexibility is improved, which facilitates the continued replacement and combination of compressor upper housings 110 and compressor lower housings 130 of different specifications to realize compressor housings 100 with different principles or functions; at the same time, modular production of the compressor housing also facilitates the installation of various internal components such as motors and pump bodies into any prefabricated structure of the compressor housing, and then welding each prefabricated structure.

[0063] Preferably, when welding is performed between adjacent prefabricated structures, the connection can be made by hot plate welding or ultrasonic welding, thereby enabling rapid assembly and seamless connection, ensuring the sealing of the compressor housing, and avoiding the risk of refrigerant leakage.

[0064] See also Figure 6 In a specific embodiment, the compressor main shell 120 includes a first shell 121 and a second shell 122. The first shell 121 and the compressor upper shell 110 form an integrated first prefabricated structure, and the second shell 122 and the compressor lower shell 130 form an integrated second prefabricated structure. The first shell 121 and the second shell 122 are welded together through welding positions.

[0065] It should be noted that the cylinder is designed as a split body and is separately combined with the compressor upper shell 110 and the compressor lower shell 130. The compressor upper shell 110 and the compressor lower shell 130 do not need to be separately injection molded, which improves production efficiency and reduces the number of welding positions, improving welding efficiency and connection reliability. After the compressor main shell 120 is split, the mold size requirements are significantly reduced, making it easier to process larger compressor shells. After the compressor upper shell 110 and the compressor lower shell 130 are separately injection molded, they can also be easily demolded separately. Any part of the compressor main shell 120 can be demolded axially along with the compressor upper shell 110 or the compressor lower shell 130.

[0066] The compressor main housing 120 can be divided into the first housing 121 and the second housing 122 in any ratio, such as 1:1, 1:2, etc., which is not limited here. When other components such as bypass lines or sensors are installed on the side of the compressor main housing 120, the compressor main housing 120 can also be divided into a larger number of housings or housings of different ratios for avoidance or processing convenience, which is not limited here.

[0067] In a specific embodiment, the compressor main shell 120 and the compressor upper shell 110 form an integrated first prefabricated structure, the compressor lower shell 130 is a second prefabricated structure, and the first prefabricated structure and the second prefabricated structure are welded together through welding positions.

[0068] It should be noted that the compressor main housing 120 axially overlaps the edge of the compressor upper housing 110. Therefore, the compressor main housing 120 and the compressor upper housing 110 can be combined for injection molding and ejected from the mold together. This eliminates the need for separate injection molding of the compressor upper housing 110, reducing the number of injection molding and welding operations, simplifying the compressor housing assembly process, and improving production efficiency.

[0069] See also Figure 7In a specific embodiment, the compressor upper shell 110 is a first prefabricated structure, the compressor main shell 120 and the compressor lower shell 130 form an integrated second prefabricated structure, and the first prefabricated structure and the second prefabricated structure are welded together through welding positions.

[0070] It should be noted that the compressor main housing 120 axially overlaps with the edge of the compressor lower housing 130. Therefore, the compressor main housing 120 and the compressor lower housing 130 can be combined for injection molding and ejected from the mold together. This eliminates the need for separate injection molding of the compressor lower housing 130, reducing the number of injection molding and welding operations, simplifying the compressor housing assembly process, and improving production efficiency.

[0071] See also Figure 3 In a specific embodiment, the compressor upper shell 110 is a first prefabricated structure, and the compressor lower shell 130 is a second prefabricated structure; the multiple prefabricated structures also include a third prefabricated structure, which is the compressor main shell 120. The first prefabricated structure, the third prefabricated structure, and the second prefabricated structure are welded together in sequence through welding positions.

[0072] It should be noted that the compressor upper shell 110, the compressor main shell 120, and the compressor lower shell 130 are all injection molded separately to achieve a completely modular design, which is convenient for replacing parts according to size requirements, such as replacing the compressor main shell 120 of different lengths to adapt to different volume requirements.

[0073] In a specific embodiment, the welding position includes: a first matching structure 141 and a second matching structure 142 , and the first matching structure 141 and the second matching structure 142 are sleeved and matched, and then welded together.

[0074] It should be noted that the first matching structure 141 and the second matching structure 142 can be installed in a limited position, which can play a physical positioning effect before the compressor upper shell 110 is welded to the compressor main shell 120, or before the compressor main shell 120 is welded to the compressor lower shell 130, to avoid welding misalignment; and the socket structure can increase the welding contact area and improve the welding strength.

[0075] The first mating structure 141 and the second mating structure 142 can be stepped mating structures or mating structures with at least one inclined surface to achieve lateral limiting. For example, the first mating structure 141 is provided at the end of the compressor main housing 120, and the second mating structure 142 is provided at one end of the compressor upper housing 110 or the compressor lower housing 130 close to the compressor main housing 120. The first mating structure 141 is an inner ring structure, and the second mating structure 142 is an outer ring structure. The second mating structure 142 is sleeved on the outside of the first mating structure 141 to achieve positioning and installation of the compressor upper housing 110 and the compressor main housing 120, or positioning and installation of the compressor main housing 120 and the compressor lower housing 130.

[0076] See also Figure 3 and Figure 7 In a specific embodiment, the compressor housing further includes: a positioning foot 151, the positioning foot 151 is made of plastic, and the positioning foot 151 and the compressor lower housing 130 form an integrated second prefabricated structure.

[0077] It should be noted that the positioning foot 151 is used to support the compressor housing and stably install the compressor housing on the shock-absorbing spring; the positioning foot 151 uses plastic to further reduce weight and facilitate transportation, and the positioning foot 151 does not require a paint interface to be waterproof and corrosion-resistant, which simplifies the process flow; the positioning foot 151 and the compressor lower housing 130 are integrally injection molded, which further improves the injection molding efficiency, eliminates the assembly gap between the foot and the housing, and improves the installation stability; and compared with bolt fixing, one-piece injection molding has no risk of loosening and reduces maintenance costs.

[0078] See also Figure 2 and Figure 6 In another specific embodiment, the compressor housing further includes: a positioning leg 151 and an embedded reinforcement plate 152, the embedded reinforcement plate 152 is made of metal or alloy, the embedded reinforcement plate 152 is embedded in the compressor lower housing 130, and the positioning leg 151 is welded to the embedded reinforcement plate 152; wherein, the embedded reinforcement plate 152 is installed in the mold of the compressor lower housing 130, and the compressor lower housing 130 is injection molded so that the embedded reinforcement plate 152 and the compressor lower housing 130 are embedded to form a second prefabricated structure.

[0079] It should be noted that the embedded reinforcement plate 152 is used to improve the strength of the compressor lower shell 130, improve the load-bearing capacity of the compressor shell and the stability of installation; after the compressor lower shell 130 is injection molded, the embedded reinforcement plate 152 can be tightly matched with the compressor lower shell 130 to avoid loose connection caused by vibration, thereby stably installing the positioning support foot 151 on the embedded reinforcement plate 152.

[0080] Preferably, the embedded reinforcing plate 152 is a disc structure having a smaller diameter than the compressor lower housing 130. The embedded reinforcing plate 152 has grooves or protrusions circumferentially. After the compressor lower housing 130 is injection molded, protrusions or grooves are formed circumferentially that mate with the embedded reinforcing plate 152, achieving interlocking engagement between the two. For example, the embedded reinforcing plate 152 has multiple equally spaced grooves circumferentially. The grooves may be fan-shaped, square, or triangular, but this is not limited here. The number of grooves may be 3, 4, 6, or the like, arranged circumferentially.

[0081] Furthermore, the embedded reinforcement plate 152 has a mounting surface exposed at the bottom of the compressor lower shell 130, which is used to install the positioning leg 151, wherein a threaded hole can be provided on the mounting surface for locking the positioning leg 151 through a fastener, and the positioning leg 151 can also be directly welded on the mounting surface, which is not limited here.

[0083] It should be noted that the terminal insert 161 is used to power and control the compressor housing 100, and is made of, for example, copper alloy; the screw insert 162 is used to fix the compressor housing 100 to other components, and is made of, for example, stainless steel; the air pipe insert 163 is used to transport gas in or out, and is made of, for example, aluminum alloy. The terminal, screw, and air pipe can be stably installed on the compressor upper housing 110 in the form of inserts. After injection molding the compressor upper housing 110, the terminal, screw, and air pipe can be tightly matched with the compressor upper housing 110, achieving stable wiring, screw installation, and air pipe gas conduction functions; there is no need to subsequently fix the terminal, screw, and air pipe. Injection molding can make the installation of the terminal, screw, and air pipe easier, improve airtightness, and protect the integrity of the compressor housing; the compressor housing is made of plastic, which also serves as insulation for the terminal insert 161.
