[0033] As a core mechanical device in the industrial field for increasing gas pressure, the compressor essentially performs work on the gas through the orderly movement of mechanical components, increasing the kinetic energy of gas molecules and converting it into potential energy, thereby meeting the high-pressure gas requirements under different operating conditions. These devices are widely used in many fields such as chemical, petroleum, metallurgy, refrigeration, and pneumatics. Whether it's pressurizing and transporting raw materials in chemical production, circulating refrigerant in air conditioning systems, or supplying power to industrial pneumatic equipment, the compressor plays an indispensable role. Its working principle encompasses two basic types: positive displacement and dynamic. The former achieves pressurization by changing the gas volume, while the latter relies on high-speed moving components to impart kinetic energy to the gas and then convert it into pressure energy. The centrifugal compressor is a typical representative of the dynamic compressor type.

[0034] In traditional compressor systems, controllers and sensors are discretely arranged with separate functions. This low integration has become a bottleneck restricting the miniaturization design of compressors. Specifically, controllers, such as rectifier control boards, and sensors, such as current sensors, are installed separately due to their independent functions. Each requires its own independent support structure and signal transmission path, resulting in a loose overall layout and occupying a large amount of axial and radial space. The discrete sensors and controllers rely on external cables for signal interaction, which not only increases wiring complexity but also easily leads to electromagnetic coupling interference and signal attenuation problems between the copper busbars and sensor cables. Furthermore, the need for cable fixing further encroaches on limited space. In addition, controllers require heat dissipation, and the independently designed controller heat dissipation structure and the boss space required for sensor installation are difficult to optimize in coordination with the compressor's structure, exacerbating the contradiction between functional integration and space constraints during miniaturization. This discrete arrangement makes the controller and sensors isolated functional units inside the compressor, making it impossible to reduce redundant design through structural reuse, thus becoming a technical obstacle hindering the development of compact compressors.

[0035] Reference Figure 1 and Figure 2 Therefore, this utility model proposes an integrated structure for a compressor controller and sensor, providing a highly integrated controller and sensor mounting method to facilitate the miniaturization design of the compressor. Specifically, the integrated controller and sensor structure proposed in this utility model includes a support plate 1 and a rectifier control plate 2. The top surface of the support plate 1 has a mounting groove 11, and the rectifier control plate 2 is disposed in the mounting groove 11. The bottom surface of the support plate 1 is provided with several reinforcing ribs 12 to improve the structural strength of the support plate 1. The bottom surface of the support plate 1 is provided with several copper busbars 3, which are arranged side by side. One end of each copper busbar 3 is fixed to the bottom surface of the support plate 1, and the other end extends toward one side of the support plate 1. The copper column 4 extends from the support plate 1 for circuit connection with the compressor. The bottom surface of the support plate 1 is also provided with several connecting copper columns 4, which are arranged side-by-side on the bottom surface of the support plate 1. Each connecting copper column 4 corresponds one-to-one with the output copper busbar 3, meaning one end of the connecting copper column 4 is fixedly connected to the end of the output copper busbar 3 located on the support plate 1. The length direction of the connecting copper column 4 is perpendicular to the bottom surface of the support plate 1. In this invention, there are three output copper busbars 3 and three connecting copper columns 4. A current sensor 5 is fitted onto each connecting copper column 4, and the current sensor 5 is used to monitor the current during compressor operation. Each connecting copper column 4 is fitted with a current sensor 5, or at least one connecting copper column 4 is fitted with at least one current sensor 5.

[0036] Refer to 3 and Figure 4 In this invention, the mounting groove 11 on the top surface of the support plate 1 is used to accommodate the rectifier control board 2, and the bottom surface integrates the outgoing copper busbar 3, the connecting copper column 4, and the current sensor 5. This achieves the concentration of the electrical connection components of the controller and the sensor on the same substrate, making the overall structure compact. Compared with the traditional controller and sensor placement, it saves a lot of installation space, thereby significantly improving the utilization rate of the compressor's internal space and meeting the miniaturization design requirements of the compressor. In addition, the reinforcing rib 12 on the bottom surface of the support plate 1 enhances the rigidity of the support plate 1, reduces the vibration deformation of the support plate 1 during high-speed operation of the compressor, ensures the relative positional accuracy of the current sensor 5 and the connecting copper column 4, and avoids signal acquisition errors caused by contact between the current sensor 5 and the connecting copper column 4. The mounting groove 11 forms a physical limit for the rectifier control board 2, and together with the design of the reinforcing rib 12, the vibration amplitude of the control board under complex operating conditions is significantly reduced.

[0037] It should be noted that the connecting copper column 4 is used to install the support plate 1 onto the compressor. That is, the function of the connecting copper column 4 is to support and fix it, and it is not directly used to transmit electrical signals. However, the connecting copper column 4 can be changed according to design requirements. That is, the connecting copper column 4 can also be designed to be conductive. It should be noted that in order to avoid the current sensor 5 being affected, the connecting copper column 4 with the current sensor 5 should preferably only be used to fix the support plate 1 and not be conductive.

[0038] Refer to 3 and Figure 4 Based on the above, the bottom surface of the support plate 1 is also provided with several supporting copper columns 41. The supporting copper columns 41 and the connecting copper columns 4 are used together to install the support plate 1 onto the compressor. The supporting copper columns 41 and the connecting copper columns 4 work together to provide support and fixation for the support plate 1. In addition, the current sensor 5 is not provided on the supporting copper column 41, but is only provided on the connecting copper column 4. Alternatively, it can be simply understood that the connecting copper column 4 is connected to the outgoing copper busbar 3, and the supporting copper column 41 is not connected to the outgoing copper busbar 3. The supporting copper column 41 and the connecting copper column 4 are actually the same concept, but they need to be distinguished due to their different design requirements, positions, and connections with other structures. It should be noted that the positions of the current sensors 5 on the connecting copper columns 4 can be adjusted according to actual usage needs. As mentioned above, one current sensor 5 can be installed on each connecting copper column 4, or multiple current sensors 5 can be installed on some or all of the connecting copper columns 4, as long as the design requirements are met.

[0039] It should be noted that at least one current sensor 5 is provided on the outer wall of at least one connecting copper pillar 4, which can be understood as:

[0040] (1) The number of connecting copper posts 4 is greater than the number of current sensors 5. In this case, the current sensors 5 can be paired up on the connecting copper posts 4, and some connecting copper posts 4 may not have current sensors 5 mounted on them. For example, there are six connecting copper posts 4 and three current sensors 5, with the three current sensors 5 mounted on any three of the six connecting copper posts 4, and the other three connecting copper posts 4 may not have current sensors 5 mounted on them; or, the current sensors 5 may be paired up on the connecting copper posts 4, with the other connecting copper posts 4 may not have current sensors 5 mounted on them. For example, there are six connecting copper posts 4 and three current sensors 5, with the three current sensors 5 mounted on all six connecting copper posts 4. In some cases, current sensors 5 are installed on any one of the connecting copper pillars 4, while the other five connecting copper pillars 4 are not fitted with current sensors 5. Alternatively, current sensors 5 can be installed on the connecting copper pillars 4 in a one-to-one or many-to-one manner, while the other connecting copper pillars 4 are not fitted with current sensors 5. For example, there are six connecting copper pillars 4 and three current sensors 5. Two current sensors 5 are installed on any one of the six connecting copper pillars 4, and the third current sensor 5 is installed on any one of the remaining five connecting copper pillars 4. The remaining four connecting copper pillars 4 are not fitted with current sensors 5. It should be noted that the above examples are only for the purpose of understanding the scheme and are not intended to limit the specific number of connecting copper pillars 4 and current sensors 5.

[0041] (2) The number of connecting copper posts 4 is less than the number of current sensors 5. In this case, multiple current sensors 5 can be mounted on all the connecting copper posts 4, or they can be selected to be mounted on some of the connecting copper posts 4. The connecting copper posts 4 with current sensors 5 can have only one current sensor 5 mounted on them, or multiple current sensors 5 can be mounted on them. For example, there are four connecting copper posts 4 and six current sensors 5. The six current sensors 5 can be selected to be mounted on one connecting copper post 4, or they can be selected to be mounted on two connecting copper posts 4 (the number of current sensors mounted on each connecting copper post 4 is not limited), or they can be selected to be mounted on four connecting copper posts 4 (i.e., at least one current sensor 5 is mounted on each connecting copper post 4). There are no specific limitations on this. It should be noted that the above examples are only for the purpose of understanding the scheme and are not intended to limit the specific number of connecting copper posts 4 and current sensors 5.

[0042] (3) The number of connecting copper pillars 4 is equal to the number of current sensors 5. At this time, the current sensors 5 can be selected to be set on the connecting copper pillars 4 in a one-to-one correspondence (the connection method described above), or multiple current sensors 5 can be selected to be fitted on some of the connecting copper pillars 4. The connecting copper pillar 4 fitted with the current sensor 5 can have only one current sensor 5 fitted on it, or multiple current sensors 5 can be fitted on it, as mentioned above, and will not be elaborated on further here.

[0043] Further reference Figure 3 , Figure 3 Three connecting copper posts are provided. At least two of these posts can be equipped with current sensors, or a single post can have only one sensor. Alternatively, two sensors can be placed on each of the three posts in pairs, or all three posts can have sensors, resulting in three sensors. However, it is important to emphasize that the current sensor 5 is not in contact with the connecting copper post 4 to avoid interference from the connecting copper post 4.

[0044] To acquire and control the current sensor 5, the integrated structure proposed in this invention also includes a sensor control board 6. The sensor control board 6 is L-shaped or rectangular, and at least one current sensor 5 is fixedly connected to the sensor control board 6. In this invention, when only one current sensor 5 is fitted on each or part of the connecting copper pillar 4, all current sensors 5 are fixedly connected to the sensor control board 6. When at least two sensors are fitted on each or part of the connecting copper pillar 4, at least one current sensor 5 on each or part of the connecting copper pillar 4 is fixedly connected to the sensor control board 6. In this invention, the current sensor 5 is fixed to the sensor control board 6 by welding, and each current sensor 5 is electrically connected to the sensor control board 6 to output or receive signals. The welding fixing method effectively improves the installation accuracy of the current sensor 5, thereby improving the acquisition accuracy of the current signal.

[0045] Reference Figure 3 and Figure 5Specifically, the sensor control board 6 is also located on the bottom surface of the support plate 1. The end of the connecting copper column 4 passes through the end of the sensor control board 6 where the current sensor 5 is fixed before connecting to the outgoing copper busbar 3. Thus, the sensor control board 6 can be positioned by the connecting copper column 4 during installation, thereby improving the convenience of the overall structure installation. The bottom surface of the support plate 1 is provided with several first connecting columns 13. When the sensor control board 6 is L-shaped, the several first connecting columns 13 are also distributed in an L-shape on the support plate 1, that is, the line connecting the positions of the first connecting columns 13 is also approximately L-shaped to fit the shape of the sensor control board 6. In this utility model, bolts are used to fix the sensor control board 6 to the first connecting columns 13. It should be noted that the L-shaped distribution of the connecting columns... The connecting posts (usually 3-4) form a stable triangular support structure, which evenly distributes the installation stress of the sensor control board 6 to the edge of the support plate 1, avoiding localized stress concentration. This makes it particularly suitable for compressors with high vibration amplitude. It should be noted that the setting position of the first connecting post 13 does not affect the shape of the sensor control board 6. In other words, the setting of the first connecting post 13 avoids interference between the reinforcing rib 12 and the sensor control board 6. Moreover, the standardized setting of the first connecting post 13 can be compatible with sensor control boards 6 of different sizes, thereby supporting quick replacement and maintenance. When it is necessary to upgrade or replace the sensor control board 6, it is not necessary to disassemble the entire support plate 1. Only the bolts of the first connecting post 13 need to be loosened to complete the module replacement, thus shortening the maintenance time.

[0046] Furthermore, the support plate 1 is provided with two connecting parts 7 for connecting to the compressor body or other external structures or equipment such as compressor parts. Considering the plurality of outgoing copper busbars 3 as a whole, the two connecting parts 7 are respectively provided on both sides of the plurality of outgoing copper busbars. The two connecting parts 7 are roughly parallel to the extension direction of the outgoing copper busbars 3 to facilitate the connection between the outgoing copper busbars 3 and external components such as the compressor body. The connecting parts 7 are roughly hollow square prisms with a plurality of holes and grooves for connecting to external structures or equipment. The symmetrically distributed connecting parts 7 on both sides provide double mechanical fixing points, which improves the connection rigidity between the support plate 1 and external components such as the compressor body, reduces the displacement under axial load, and thus avoids the risk of poor contact or breakage of the outgoing copper busbars 3 due to shaking.

[0047] Reference Figure 2 and Figure 5Considering that the sensor control board 6 and the rectifier control board 2 need to dissipate heat during operation, in this utility model, a fan assembly 8 is provided between two adjacent copper busbars 3 to provide air cooling for the sensor control board 6 and the rectifier control board 2. Taking the utility model with three copper busbars 3 as an example, there are two notches between the three copper busbars 3, and a fan assembly 8 is provided in each of these notches. Specifically, the fan assembly 8 includes a mounting bracket 81 and a fan 82. The mounting bracket 81 is located on the side of the support plate 1, that is, between two adjacent copper busbars 3. The mounting bracket 81 is provided with several holes and grooves for the fan 82 to be inserted. After the fan 82 is inserted into the groove, bolts can be driven into the holes on the mounting bracket 81 to fix the fan 82. The fan assembly 8 can effectively provide air cooling for the rectifier control board 2 and the sensor control board 6, thereby reducing the operating temperature of the rectifier control board 2 and the sensor control board 6 during compressor operation, and thus ensuring the normal operation of the rectifier control board 2 and the sensor control board 6.

[0048] Reference Figure 4 and Figure 5 It should be noted that, in order for the fan assembly 8 to simultaneously dissipate heat from both the rectifier control board 2 and the sensor control board 6, the support plate 1 is positioned at the midpoint of the height of the mounting bracket 81, roughly bisecting the mounting bracket 81. This allows the top and bottom of the mounting bracket 81 to protrude beyond the support plate 1, enabling the airflow generated by the fan 82 to pass over the top and bottom surfaces of the support plate 1. Correspondingly, to improve the cooling effect of the fan assembly 8 on the rectifier control board 2 within the mounting slot 11, the side wall of the mounting slot 11 has ventilation notches 111 corresponding to the mounting bracket 81. These ventilation notches 111 are used for cooling the rectifier control board 2. The ventilation notch 111 on plate 2 guides the airflow from fan 82 to directly sweep the top and bottom surfaces of the rectifier control plate 2, thereby better cooling the rectifier control plate 2. To further improve the cooling effect of fan assembly 8 on rectifier control plate 2, a second connecting post 14 is protruding in the mounting groove 11. The rectifier control plate 2 can be fixed in the mounting groove 11 by bolts and the second connecting post 14. The setting of the second connecting post 14 actually raises the rectifier control plate 2, leaving a gap between the bottom surface of the rectifier control plate 2 and the bottom of the mounting groove 11. This allows the airflow from fan assembly 8 to sweep the top and bottom surfaces of rectifier control plate 2, improving the cooling effect of fan assembly 8 on rectifier control plate 2. The setting of the first connecting post 13 is similar. The setting of the first connecting post 13 creates a gap between the bottom surface of sensor control plate 6 and support plate 1, allowing the airflow generated by fan 82 to pass through the gap, thereby improving the cooling effect of fan 82 on sensor control plate 6.

[0049] In order to guide the airflow of fan 82 and ensure the cooling effect of the airflow generated by fan 82, a guide slope 112 is also provided in the ventilation gap 111. The guide slope 112 can convert the high-speed airflow blown out by fan 82 into laminar flow parallel to rectifier control board 2, reduce the generation of eddies, and thus ensure the cooling effect of fan 82 on rectifier control board 2 and sensor control board 6.

[0050] Reference Figure 3 Correspondingly, in order to control the fan 82, a fan control board 9 is also provided on the bottom surface of the support plate 1. The fan control board 9 is electrically connected to the fan 82. The fan control board 9 can control parameters such as the start time and speed of the fan 82, thereby ensuring the heat dissipation effect of the fan assembly 8 on the overall structure. Correspondingly, referring to the setting of the first connecting post 13 and the second connecting post 14, a third connecting post 15 is also formed on the bottom surface of the support plate 1. The third connecting post 15 is also used to fix the fan control board 9 with bolts, thereby leaving a gap between the fan control board 9 and the support plate 1. The setting of the third connecting post 15 can also avoid the interference of the reinforcing rib 12 on the installation of the fan control board 9.

[0051] It should be noted that, in this utility model, in addition to the positions where the fan assembly 8 and the connecting part 7 are located, the support plate 1 is also provided with a number of weight-reducing holes arranged in an array around its perimeter, and a number of wire passage grooves or mounting protrusions are also provided. It should be noted that the weight-reducing holes can also be used for wire passage, and the specific positions and numbers of the wire passage grooves and mounting protrusions can be adjusted according to factors such as the actual design requirements of the compressor. Alternatively, the positions and numbers of the wire passage grooves and mounting protrusions can be adjusted for compatibility, i.e., applicability to various different models of compressors, in order to improve the adaptability of the overall structure in different compressors.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
