DETAILED DESCRIPTION

[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0037] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. In this disclosure, unless otherwise indicated, the directional words used, such as "inside" and "outside", are defined for the corresponding parts themselves. The terms "first" and "second" used in this disclosure are used to distinguish one element from another element and do not have order and importance.

[0038] The present disclosure provides a compressor, referring to Figure 1 and Figure 2 The compressor includes a compression part 200 and an electric control part 300. The compression part 200 includes a motor assembly 210 and may also include a scroll assembly 230. The motor assembly 210 is controlled to rotate by the electric control part 300, thereby driving the scroll assembly 230 to work, wherein the moving disk 231 of the scroll assembly 230 can be driven by the motor assembly 210, so that the moving disk 231 and the static disk 232 generate relative motion to perform compression. The compressor also includes a Hall acquisition part 400, which is used to collect the rotation information of the motor assembly 210, so as to compare the collected rotation information of the motor assembly 210 with the set target position, thereby adjusting the direction and speed of the motor assembly 210, so that the actual rotation position of the motor assembly 210 is consistent with the target position. In the embodiment of the present disclosure, the Hall acquisition unit 400 is integrated on the electric control unit 300. Thus, compared with the related art in which the electric control unit of the Hall acquisition unit 400 is separately provided, there is no need to separately assemble the electric control unit of the Hall acquisition unit 400, and at least the electrical connection harness between the electric control unit of the Hall acquisition unit 400 and the electric control unit of the compressor is reduced, thereby reducing the cost and improving the reliability of the operation of the compressor.

[0039] Reference Figure 1 and Figure 2 The compressor further includes a casing 100, which is used to accommodate the internal structure of the compressor. In the embodiment of the present disclosure, the compression part 200 and the electronic control part 300 can be separated by the casing 100, that is, the two are not accommodated in the same accommodation space. That is, the Hall acquisition part 400 is placed at a position separated from the compression part 200 by the casing 100.

[0040] Through the above technical solution, the Hall acquisition unit 400 for detecting the rotation information of the compressor is set separately from the compression unit 200, so as to avoid the Hall acquisition unit 400 from contacting with the refrigerant and refrigeration oil of the compression unit 200 and causing corrosion and aging, thereby improving durability and reliability, and also avoiding the increase in the cost of components and materials required to consider compatibility issues. Moreover, the Hall acquisition unit 400 does not need to be placed in the compression unit 200, so the risk of refrigerant leakage inside the compression unit 200 can be avoided.

[0041] Combination Figure 3The Hall acquisition unit 400 may include a Hall chip 410, a magnetic ring 510 may be provided on the compression unit 200, the motor assembly 210 may include a rotor 211 and a stator 212, the magnetic ring 510 may be configured to rotate synchronously with the rotor 211 of the motor assembly 210, and the Hall chip 410 is used to detect the change in the magnetic field generated by the magnetic ring 510. When the rotor 211 rotates and drives the magnetic ring 510 to rotate synchronously, a rotating magnetic field is generated, and the Hall chip 410 can detect the change in the magnetic field to determine the rotation speed according to the change in the magnetic field, thereby controlling the motor assembly 210 through the detected rotation speed and the target rotation speed.

[0042] Combination Figure 2 and Figure 3 In order to ensure that the Hall acquisition unit 400 can continuously and reliably detect, in the embodiment of the present disclosure, the magnetic ring 510 is aligned with the Hall chip 410 in the extension direction of the rotation axis O of the rotor 211. The alignment here may refer to the alignment of the centers of the two, so that the projections of the centers of the two overlap in the extension direction of the rotation axis O, and ensure that the magnetic field of the magnetic ring 510 can cover the Hall chip 410, so that the Hall chip 410 can accurately detect.

[0043] Combination Figures 1 to 3 , the compression part 200 may include a crankshaft 220 that rotates synchronously with the rotor 211. Specifically, the crankshaft 220 may be inscribed in the inner ring of the rotor 211. After the stator 212 of the motor assembly 210 is energized, the rotor 211 is driven to rotate, and the rotor 211 drives the crankshaft 220 to rotate. The crankshaft 220 may be connected to the moving disk 231, thereby driving the moving disk 231 to work. In this embodiment, the magnetic ring 510 may be coaxially connected to the crankshaft 220, and the coaxiality here means that the central axis of the magnetic ring 510 is coaxial with the central axis of the main shaft of the crankshaft 220. This connection method makes it easier to bring the magnetic ring 510 close to the central area and is easy to install. However, it is not excluded that in other embodiments, the magnetic ring 510 may also be coaxially connected to the rotor 211.

[0044] There can be many ways to connect the magnetic ring 510 and the crankshaft 220. For example, the magnetic ring 510 can be interference fit on the outer circumference of the crankshaft 220, or the magnetic ring 510 and the crankshaft 220 can be connected through a pin 610. The magnetic ring 510 can be connected to one axial end of the crankshaft 220. On the one hand, the pin 610 connection is easier to implement than the interference fit method. On the other hand, the pin 610 can provide the magnetic ring 510 with an axial distance close to the Hall chip 410 to ensure a good detection effect.

[0045] Taking into account the thickness of the housing 100, the size of the Hall chip 410 and the magnetic ring 510, the inner diameter and outer diameter of the magnetic ring 510 are limited because the magnetic ring 510 is set in a limited space. Therefore, it is necessary to shorten the distance between the magnetic ring 510 and the Hall chip 410 as much as possible within the limited space to meet the magnetic induction intensity that can be sensed by the Hall chip 410.

[0046] To this end, in one embodiment of the present disclosure, the magnetic ring 510 can be connected to the end of the compression part 200 close to the electric control part 300, so that the magnetic ring 510 is as close to the electric control part 300 as possible, and thus close to the Hall acquisition part 400 integrated on the electric control part 300. When the magnetic ring 510 is set on the crankshaft 220, the magnetic ring 510 can be connected to one end of the crankshaft 220 by means of the above-mentioned pin 610.

[0047] Reference Figure 3 , the housing portion 100 may include a partition shell 101 disposed between the Hall chip 410 and the magnetic ring 510. In one embodiment, in order to ensure the distance between the magnetic ring 510 and the Hall chip 410, a receiving groove 102 protruding toward the Hall chip 410 may be formed on the partition shell 101, and the magnetic ring 510 may be disposed in the receiving groove 102. It can be understood here that the magnetic ring 510 is accommodated in the receiving groove 102, but is not in contact with the receiving groove 102. It should also be noted that the receiving groove 102 is arranged to adapt to the arrangement of the electric control unit 300 under the premise that the partition shell 101 meets the compact arrangement, that is, on the basis of the original setting position of the partition shell 101, the distance between the magnetic ring 510 and the electric control unit 300 is further shortened by the receiving groove 102.

[0048] Through the above technical solution, the structure of the partition shell 101 is used to form the receiving groove 102, so that the magnetic ring 510 can be closer to the electric control part 300, and thus closer to the Hall acquisition part 400. By designing the receiving groove 102 structure in a relatively small space to place the magnetic ring 510, the distance between the magnetic ring 510 and the Hall acquisition part 400 meets the detection requirements, so as to ensure that the magnetic ring 510 can ensure the magnetic induction intensity at the position of the Hall chip 410.

[0049] In addition to shortening the distance by changing the position of the magnetic ring 510, the distance can also be shortened by changing the position of the Hall chip 410. For example, a groove protruding toward the compression part 200 can be formed on the partition shell 101, that is, opposite to the above-mentioned receiving groove 102, and the Hall chip 410 can be arranged in the groove. Figure 5A padding member 420 may be provided on the side of the Hall chip 410 facing away from the magnetic ring 510, so that the Hall chip 410 is padded and close to the magnetic ring 510. The padding member 420 may be arranged in close contact with the Hall chip 410, or may be arranged to indirectly padded the Hall chip 410 through other structures. For example, when the Hall chip 410 is connected to the control circuit board 310 of the electric control unit 300, the padding member 420 may also be used to padded the control circuit board 310, thereby indirectly padded the Hall chip 410.

[0050] Through the above technical solution, by using the setting of the cushioning member 420, the Hall chip 410 can be closer to the compression part 200, and thus closer to the magnetic ring 510. By setting the cushioning member 420 in a relatively small space of the electric control part 300 to set the Hall chip 410, the distance between the Hall chip 410 and the magnetic ring 510 meets the detection requirements, so as to ensure that the magnetic ring 510 can ensure the magnetic induction intensity at the position of the Hall chip 410.

[0051] The electric control unit 300 may include a control circuit board 310, and the padding member 420 may include a Hall circuit board. The Hall chip 410 is mounted on the Hall circuit board, and the Hall circuit board is disposed on the control circuit board 310. The Hall circuit board can realize the connection between the control circuit board 310 and the Hall chip 410, and can also take into account the padding effect. Figure 5 The Hall circuit board can be connected to the control circuit board 310 through the pin 421, realizing the integration of the acquisition circuit and the control. Figure 4 , the Hall chip 410 can be directly connected to the control circuit board 310 .

[0052] In the embodiment of the present disclosure, the Hall chip 410 and the magnetic ring 510 can be configured to be spaced 7 mm to 15 mm apart in the extending direction of the rotation axis O of the rotor 211. Within this distance range, the Hall chip 410 can be guaranteed to sense the magnetic field. The implementation methods of this distance include but are not limited to one or more of the above.

[0053] Combine the following Figures 6 to 8 The electronic control unit 300 in the embodiment of the present disclosure will be described.

[0054] The electric control unit 300 may include a plurality of IGBT (Insulated Gate Bipolar Transistor) components 320. The IGBT components 320 are the control center of the compressor and are used to drive the compressor to operate. In the prior art, IGBT components are mostly arranged in parallel and side by side. When the electric control unit 300 is used to install the Hall acquisition unit 400, this arrangement will occupy a large space. Therefore, in order to solve this problem, in the embodiment of the present disclosure, a plurality of IGBT components 320 can be arranged circumferentially around the Hall acquisition unit 400.

[0055] Through the above technical solution, multiple IGBT components 320 are arranged circumferentially so as to effectively utilize the circumferential space of the Hall acquisition unit 400. In the embodiment of the present disclosure, when the electric control unit 300 is used to set the Hall acquisition unit 400, space can be effectively saved, the IGBT components 320 are reasonably laid out, the arrangement is optimized, and a compact structure of the electric control unit 300 is achieved.

[0056] Among them, the electric control part 300 may include a copper needle overmolded part 330, which may circumferentially surround the Hall acquisition part 400, and a plurality of IGBT components 320 may be electrically connected to the copper needle overmolded part 330, respectively. It can be understood that the copper needle overmolded part 330 is constructed to be hollowed out in the middle, so that the Hall acquisition part 400 can be located in the hollowed-out area, and a plurality of IGBT components 320 can be located on the periphery of the hollowed-out area to be connected to the copper needle overmolded part 330 on the outside. The IGBT components 320 are all connected to the copper needle overmolded part 330, so that the plurality of IGBT components 320 are uniformly connected to the three-phase terminal 2121 of the stator 212 through the copper needle overmolded part 330, so that the connection structure is more regular, and the layout and connection are optimized.

[0057] The copper needle overmolded part 330 can be constructed as a quadrilateral structure, the middle of the quadrilateral structure is hollowed out, and one side of the quadrilateral structure is electrically connected to the compression part 200, for example, electrically connected to the three-phase terminal 2121 through the lead 331, and the other three sides are respectively used to connect the IGBT components 320, such as Figure 8 As shown. This method of arranging components on each side of the copper needle overmolded part 330 for connection can effectively utilize space, so that the installation space can still meet the requirements when the Hall acquisition unit 400 is introduced. In other embodiments, the shape of the copper needle overmolded part 330 can also be a pentagon or a circle, or other irregular shapes, which can be adjusted according to factors such as the number of components to be connected.

[0058] The number of IGBT components 320 may be six, and every two IGBT components 320 may be connected to one side of the copper needle overmolded component 330 , so that the number of IGBT components 320 on each side is the same and the layout is more regular.

[0059] In the embodiment of the present disclosure, the electric control unit 300 may further include a ceramic gasket 340, the first surface of the ceramic gasket 340 is coated with a first heat-conducting layer, such as thermal grease, and the ceramic gasket 340 may be attached to the housing 100, and the IGBT component 320 is attached to the second surface of the ceramic gasket 340 opposite to the first surface, that is, attached to the side of the ceramic gasket 340 facing away from the housing 100, thereby transferring the heat generated by the IGBT component 320 to the first heat-conducting layer, and can be taken away by the low-temperature and low-pressure refrigerant in the compression unit 200 through the housing 100, so that the electric control unit 300 can operate normally. Among them, a mounting groove 341 may be formed on the housing 100, and the shape of the mounting groove 341 may match the shape of the ceramic gasket 340 to accommodate the ceramic gasket 340, and the setting of the mounting groove 341 may also prevent the IGBT component 320 from being too high after being attached to the ceramic gasket 340, thereby affecting the installation connection. The shape of the ceramic gasket 340 may also match the shape of the IGBT component 320 to better transfer the heat of the IGBT component 320 .

[0060] In order to ensure the installation reliability of the IGBT component 320, the electric control part 300 may include a pressing plate 350, which may be configured to fix the IGBT component 320 to the housing part 100. Specifically, one end of the pressing plate 350 may be fixed to the housing part 100 by a fastener, and the other end may be elastically pressed on the side of the IGBT component 320 facing away from the housing part 100. The pressing plate 350 may be configured as a spring sheet structure, and the end where the IGBT component 320 is pressed may be configured as a branch structure to minimize the contact area with the IGBT component 320 and avoid affecting the heat dissipation of the IGBT component 320.

[0061] According to an embodiment of the present disclosure, referring to Figure 4 The housing 100 may include a first housing 110 and a second housing 120 that are detachably connected. The first housing 110 is used to accommodate the compression unit 200, and the second housing 120 is used to accommodate the electronic control unit 300. The split housing 100 is convenient for the maintenance and replacement of the electronic control unit 300 or the compression unit 200 of the compressor, and the maintenance cost is low.

[0062] In the case of a split housing portion 100, the aforementioned partition shell 101 may include a portion of the first housing 110 and a portion of the second housing 120. In other words, the partition shell 101 is configured as a portion of the first housing 110 and as a portion of the second housing 120. In a first embodiment, the aforementioned receiving groove 102 may be formed on the first housing 110, and the second housing 120 may be formed with a structure matching the shape of the receiving groove 102 to fit the receiving groove 102. In a second embodiment, the receiving groove 102 may be formed as shown in FIG. Figure 4 As shown in , the aforementioned receiving groove 102 can be formed on the first shell 110, and a hole can be opened on the second shell 120 so that the receiving groove 102 protrudes. In a third embodiment, an opening can be formed on the first shell 110 for the magnetic ring 510 to pass through, and the aforementioned receiving groove 102 can be formed on the second shell 120.

[0063] When the housing 100 is an integrated structure, the aforementioned partition housing 101 may be a common part of the housing of the compression unit 200 and the housing of the electric control unit 300, such as Figure 2 and Figure 3 shown.

[0064] When the housing 100 is a split housing, the first housing 110 and the second housing 120 can be fitted together, and a second heat-conducting layer, such as heat-conducting silicone grease, is coated on the adjacent surfaces. Through the heat-conducting fitting of the two, the heat of the second housing 120 for accommodating the electric control unit 300 can be transferred to the first housing 110 for accommodating the compression unit 200, and the heat of the first housing 110 can be taken away by the low-temperature refrigerant of the compression unit 200, thereby cooling the electric control unit 300 and ensuring good performance of the electric control unit 300.

[0065] According to a second aspect of an embodiment of the present disclosure, a thermal management system is provided. The thermal management system includes the above-mentioned compressor and has all the beneficial effects of the above-mentioned compressor, which will not be described in detail here.

[0066] According to a third aspect of an embodiment of the present disclosure, a vehicle is provided, comprising the above-mentioned thermal management system and having all the beneficial effects of the above-mentioned thermal management system, which will not be described in detail here.
