[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0022] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0023] Secondly, "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the utility model. "In one embodiment" appearing in different places in this specification does not mean the same embodiment, nor is it an embodiment that is independent or alternative to other embodiments.

In addition, three-dimensional spatial dimensions including length, width and depth should be included in actual manufacturing.

[0025] Referring Figures 1-4 One embodiment of the utility model provides a compressor cylinder pressure introduction assembly device, which comprises:

[0026] The fixed scroll 1 and the cylinder wall 2 are relatively fixedly arranged, the fixed scroll 1 is located in the cylinder wall 2, and the cylinder wall 2 is used for fixedly connecting the shell of the compressor;

[0027] The movable scroll 3 matched with the fixed scroll 1 is located in the cylinder wall 2, and the movable scroll 3 works when moving relative to the fixed scroll 1;

[0028] The detection part and the pressure control part are electrically connected, the detection part is used for detecting the acting force of the movable scroll 3 on the cylinder wall 2, and the pressure control part is used for controlling the pressure in the pressure introduction channel, for example, the pressure control part can adopt an electric valve, and the pressure in the pressure introduction channel is controlled by controlling the air flow entering the pressure introduction channel;

[0029] Based on the above, the detection part and the pressure control part can be electrically connected by a control element, such as a single-chip microcomputer unit, etc. Specifically, when the detection part detects that the extrusion force of the orbiting scroll 3 on the cylinder wall 2 is too large, it indicates that the extrusion force on the fixed scroll 1 is also too large. At this time, the pressure control part reduces the pressure in the pilot passage, thereby reducing the force on the orbiting scroll 3, so as to reduce the mutual extrusion force between the two scrolls. Thus, the mutual force between the two scrolls can be maintained at an appropriate level throughout the process, thereby reducing the operating resistance and reducing the generation of mechanical wear, so as to improve the service life of the compressor.

[0030] Further, referring to Figure 1 , the fixed scroll 1 is integrally formed with the cylinder wall 2, thereby increasing the stability of the relative fixation.

[0031] Further, referring to Figures 1-4 , the orbiting scroll 3 includes a fixedly connected orbiting scroll leaf 301 and a cover plate 302, and further includes a support plate 303 in sliding connection with the cover plate 302. The sliding direction is perpendicular to the surface of the cover plate 302. The support plate 303 is used to connect the driving force of the driving motor of the compressor, so as to drive the cover plate 302 to move synchronously in the circumferential direction. The pilot passage is used to apply force to the cover plate 302. The detection part is used to detect the interaction force between the cover plate 302 and the support plate 303, so as to detect the interaction force and obtain the force of the cover plate 302 on the cylinder wall 2.

[0032] Further, referring to Figure 4 , the detection part includes a pressure testing element 4 connected between the cover plate 302 and the support plate 303. The interaction force between the cover plate 302 and the support plate 303 acts on the pressure testing element 4 to be detected. The pressure testing element 4 can specifically be a pressure strain gauge or a ceramic pressure element, etc.

[0033] Further, referring to Figure 1 , Figure 3 and Figure 4 , the support plate 303 is provided with a through hole 5, and the cover plate 302 is provided with a piston rod 6 in sliding cooperation with the through hole 5, so as to realize the sliding connection between the cover plate 302 and the support plate 303.

[0034] Further, referring to Figure 1 , the through hole 5 is also used to communicate with the pilot passage, so that the pressure in the pilot passage acts on the piston rod 6, thereby achieving the force applying effect on the cover plate 302, thereby simplifying the structure of the entire device.

Rather and more generally, specific implementations were developed to provide implementations that are functionally, economically, and / or esthetically practical, in light of ongoing technological changes having economic, business, and / or social consequences.
