[0056] The electric scroll compressor is widely used in electric commercial vehicles and passenger vehicles due to its structural advantages. For the electric scroll compressor, its components mainly include a shell, a motor, a moving and stationary disc, a controller, etc. In the past product feedback, it is found that the failure rate of the control board is relatively prominent. The electronic components constituting the control board have their temperature range, and once the range is exceeded, the components may fail, causing the compressor to fail, so the heat dissipation problem of the electric control board needs to be solved.

[0057] Based on the above starting point, a structure of a sub-bearing seat is designed to obtain a larger heat dissipation area. At the same time, the improvement of the split bearing seat structure can adapt to more types and sizes of bearings, reduce development cost, and bring better economic benefits to enterprises. Figure 3 is a perspective view of the combination of the middle and rear shells and the split bearing seat of the vehicle scroll compressor according to the present application. Figure 4 is a perspective view of the middle and rear shells of the vehicle scroll compressor according to the present application. Figure 5 is a perspective view of the split bearing seat of the vehicle scroll compressor according to the present application. As shown in Figures 3 to 5 the vehicle scroll compressor according to the present application at least includes a rear shell 10 and a split bearing seat 20. The rear shell 10 separates a control panel mounting cavity and a low-pressure cavity, and includes a threaded seat 16 and an arc-shaped groove 11 surrounding the threaded seat 16. A plurality of flow guide heat dissipation fins 15 are arranged in the arc-shaped groove 11, and a first end 12 of the arc-shaped groove 11 is connected to an air inlet 14. The split bearing seat 20 is opposite to the rear shell 10, and includes a bearing seat 22 and a circular arc plate 21 surrounding the bearing seat 22. The circular arc plate 21 covers the arc-shaped groove 11 to form a refrigerant passage for guiding the flow of refrigerant on one side of the rear shell. A second end 13 of the arc-shaped groove 11 is provided with an opening for the outflow of refrigerant from the refrigerant passage. The split bearing seat replaces the original integrated structure, expands the area of the air inlet passage, increases the heat exchange area, and enables the controller to be better cooled. At the same time, different sizes of bearings can be adapted by replacing the split bearing seat without changing the rear shell.

[0058] In a preferred embodiment, the flow guide heat dissipation fins 15 are arranged in the arc-shaped groove 11 along the extension direction of the arc-shaped groove 11, extending from the first end 12 to the second end 13, but not limited thereto.

[0059] In a preferred embodiment, the flow guide heat dissipation fins 15 divide the arc-shaped groove 11 into a first sub-passage and a second sub-passage, but not limited thereto.

[0060] In a preferred embodiment, the second end 13 of the arc-shaped groove 11 is provided with a through hole, and the through hole is connected to the first sub-passage to form a first outlet 24 for the outflow of refrigerant, but not limited thereto.

[0061] In a preferred embodiment, the second end 13 of the arc-shaped groove 11 is also provided with a notch, and the notch and the arc-shaped groove 11 form a through hole to form a second outlet 25 for the outflow of refrigerant, but not limited thereto.

[0062] In a preferred embodiment, a plurality of threaded seats 16 are arranged in the arc-shaped groove 11, and the split bearing seat 20 is provided with a plurality of threaded bosses 23. The threaded bosses 23 are screwed with the threaded seats 16 by bolts, so that the split bearing seat 20 is pressed to cover the arc-shaped groove 11 of the rear shell 10, but not limited thereto.

[0063] In a preferred embodiment, the split bearing seat 20 is further provided with a plurality of reinforcing ribs 26, one end of which is connected to the bearing seat 22 and the other end is connected to the threaded boss 23, but not limited thereto.

[0064] In a preferred embodiment, the threaded seat 16 and the arc-shaped groove 11 are integrally formed on the rear shell 10, but not limited thereto.

[0065] The present application splits the structure of the integrated rear shell and bearing seat, forming the structure of the rear shell 10 and the split bearing seat 20. In the present application, the split bearing seat 20 and the rear shell 10 are both provided with mounting holes, and the two are connected by bolts. The split bearing seat 20 covers the flow channel on the rear shell 10 and leaves an outlet for the refrigerant to enter the low-pressure cavity of the compressor. The split bearing seat 20 has a bearing mounting portion for bearing installation and fixation, which can be modified to adapt to different styles of bearings without replacing the rear shell assembly.

[0066] Thanks to the split structure of the sub-bearing seat, the part of the back of the control panel mounting surface below the sub-bearing, which was originally unable to flow through the refrigerant, can also participate in the heat exchange process with the refrigerant. The heat conduction fin 15 is directly connected to the back of the control panel mounting surface on the rear shell 10, and has good heat conduction. The heat conduction fin 15 divides the refrigerant vapor from the suction port 14, increases the heat exchange area with the refrigerant vapor, and improves the heat dissipation conditions of the controller, bringing better heat dissipation effect. The split bearing seat 20 can adapt different types and sizes of sub-bearings to the same rear shell 10, improving the adaptability range of the rear shell 10.

[0067] The embodiment of the present application also provides an electric vehicle comprising the above-mentioned vehicle scroll compressor. The related technical features and technical effects are as described above, and will not be repeated here.

[0068] In summary, the present application aims to provide a vehicle scroll compressor and an electric vehicle, which can effectively increase the heat exchange area of the back of the controller installation by using a split bearing seat structure, so that the control panel installed in the electric control panel cavity can obtain better cooling. In addition, using a split bearing seat can adapt different sizes of sub-bearings to the same compressor rear shell by only replacing the bearing seat, improving the efficiency of parts use and reducing product development cost.

[0069] The above is a further detailed description of the present application in combination with specific preferred embodiments, and the specific implementation of the present application should not be limited to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, without departing from the concept of the present application, a number of simple deductions or substitutions can be made, which should be considered as falling within the protection scope of the present application.
