In this embodiment, the compressor main housing 110, the connecting member 120 and the reservoir main cylinder 130 are made of plastic materials, which can effectively reduce the overall weight of the compressor assembly 100 compared to metal materials, and thus is more convenient for installing the internal components of the compressor or the reservoir. And, the compressor main shell 110, the connecting piece 120 and the reservoir main cylinder 130 can be demolded along the vertical direction, so that the injection molding is facilitated. The connecting piece 120 is integrally injection-molded, so that on one hand, the mounting steps of welding or clamping the connecting piece 120 with the compressor main shell 110 or the liquid storage device main cylinder 130 are reduced, the assembly efficiency is improved, and the yield is improved, on the other hand, the integral connecting effect of the compressor main shell 110, the connecting piece 120 and the liquid storage device main cylinder 130 is better, no gap exists, the integral structure is formed, the noise generated by mutual vibration is avoided, the integral plastic material is adopted, the material cost of the compressor and the liquid storage device is effectively reduced, the paint spraying and corrosion preventing procedures of the compressor and the liquid storage device are also saved, the production efficiency is improved, and the corrosion of the connecting piece 120 is avoided.

Because the compressor main housing 110 is overlapped with the edge of the compressor lower housing 150 in the axial direction, the compressor main housing 110 and the compressor lower housing 150 can be combined for injection molding and demolding together, so that the injection molding and welding times are reduced, the assembly process of the compressor assembly 100 is simplified, and the production efficiency is improved.

Preferably, the outlet tube insert 181 includes an outlet tube sleeve having a recess or protrusion to allow for engagement during injection molding of the cartridge lower cap 180. The air inlet of the air outlet pipe extends into the liquid storage device the inner cavity is near one end of the barrel upper cover 170, therefore, the air outlet pipe sleeve is arranged to avoid the inclination of the air outlet pipe and improve the installation stability of the air outlet pipe.
The invention provides a manufacturing method of a compressor assembly 100, which is used for manufacturing the compressor assembly 100 provided by any one of the technical schemes, and comprises the steps of injection molding at least part of a compressor main shell 110, a connecting piece 120 and at least part of a reservoir main cylinder 130 together to obtain an integrated structure, and separately injection molding the compressor shell and the rest of the reservoir cylinder and then welding the integrated structure.
It should be noted that, the compressor main housing 110, the connecting piece 120 and the reservoir main cylinder 130 can be injection molded together and be easily ejected, thereby improving the production efficiency. The combination of the compressor housing and the reservoir cylinder of the compressor assembly 100 through plastic injection molding and welding eliminates the corrosion prevention process required by metal processing, reduces the number of parts through an integral structure, and effectively avoids vibration noise caused by assembly errors. Meanwhile, the plastic shell does not need surface paint spraying treatment, so that the production flow is simplified and the emission of volatile organic compounds is reduced.
In a specific embodiment, the compressor housing and the remainder of the accumulator barrel are injection molded separately and welded to the unitary structure, comprising:
Separately injection molding the compressor upper case 140 and/or the compressor lower case 150, and then welding with the compressor main case 110 in an integrated structure;
and/or, the cartridge upper cover 170 and/or the cartridge lower cover 180 are injection molded separately and then welded to the reservoir main cartridge 130 in an integrated structure.
It should be noted that the compressor assembly 100 includes a compressor housing formed by welding the compressor upper housing 140, the compressor lower housing 150, and the compressor main housing 110, and a reservoir cylinder formed by welding the cylinder upper cover 170, the cylinder lower cover 180, and the reservoir main cylinder 130. The upper shell 140, the lower shell 150, the upper shell 170 and the lower shell 180 are made of plastic materials, so that the weight of the upper shell is further reduced, the material cost is reduced, the paint spraying and corrosion preventing requirements are reduced, and the processing efficiency is improved. At least part of the upper compressor housing 140, the lower compressor housing 150, the upper cylinder cover 170 and the lower cylinder cover 180 are respectively injection-molded as independent components, so that components with different specifications can be replaced conveniently, the complexity of the die can be reduced, and the molding precision of the components can be improved.
In a specific embodiment, after the injection molding of the compressor main housing 110, the motor of the compressor is installed at one end of the compressor main housing 110 close to the compressor upper housing 140, the pump body is installed at one end of the compressor main housing 110 close to the compressor lower housing 150, the pump body is fixed through a plurality of bypass line inserts on the side surface of the compressor main housing 110, and then the compressor upper housing 140, the compressor main housing 110 and the compressor lower housing 150 are subjected to ultrasonic welding, so that the sealing and fixing of the compressor housings are realized, and therefore, the installation of each internal element of the compressor is facilitated.
In a specific embodiment, after the reservoir main cylinder 130 is injection molded, the filter is installed in one end of the reservoir main cylinder 130 near the cylinder upper cover 170, and then the cylinder upper cover 170, the reservoir main cylinder 130 and the cylinder lower cover 180 are welded to perform ultrasonic welding, so as to realize sealing and fixing of the reservoir cylinder.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention should be assessed accordingly to that of the appended claims.
