[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] In the related art, some process holes are usually set on the bus of the compressor, and some of the process holes are close to the pins of the power device. When the compressor works under certain specific environments, water vapor or condensed water will be generated on the surface of the bus. At this time, the water vapor or condensed water will cause a short circuit between the copper bar and the pin, which originally had a long enough creepage distance, causing the power device to burn out and the compressor to fail and be damaged.

[0043] Reference below Figure 1-Figure 8 A compressor 2 according to an embodiment of the present invention is described.

[0044] The compressor 2 according to the present invention comprises a housing 21, a power device 11, a busbar 12 and an electric control board 13. A motor cavity and an electric control cavity 23 are formed inside the housing 21. A stator assembly 24 and a rotating shaft 25 matched with the stator assembly 24 are arranged in the motor cavity. The stator assembly 24 is provided with a terminal 26. A plurality of pins 111 are formed on one side of the power device 11 in the thickness direction. The busbar 12 is arranged on one side of the power device 11 in the thickness direction. A first hole 123 suitable for the pins 111 to pass through is formed on the busbar 12. 12 is connected to the terminal 26; the electric control board 13 is arranged on the side of the bus 12 away from the power device 11, the electric control board 13 is electrically connected to the power device 11 through the pin 111, and the electric control board 13 is electrically connected to the bus 12; wherein, a bus copper bus 121 electrically connected to the electric control board 13 is arranged in the bus 12, and a second hole 124 penetrating to the bus copper bus 121 is formed on the surface of the bus 12, and a protruding first partition rib 141 is formed on the surface of the bus 12, and the first hole 123 and the second hole 124 are arranged on both sides of the first partition rib 141.

[0045] The power device 11 , busbar 12 , electric control board 13 and other structures arranged in the electric control chamber 23 of the compressor 2 according to the present invention may be collectively referred to as the electric control assembly 1 in this application.

[0046] The compressor 2 is provided with a housing 21 and a cover plate 22. The housing 21 has a motor cavity for accommodating a stator assembly 24 and a rotating shaft 25 matched with the stator assembly 24. The stator assembly 24 is provided with a terminal 26, which is connected to a busbar 121. The electric control assembly 1 is arranged at the end of the housing 21, and the power device 11, the busbar 12 and the electric control board 13 are stacked in sequence in a direction away from the housing 21. The cover plate 22 is arranged on the housing 21 and forms an electric control cavity 23 for accommodating the electric control assembly 1 between the housing 21. Figure 8As shown, the compressor 2 achieves maximum utilization of space by stacking the various parts of the electronic control component 1 (power device 11, bus 12, and electronic control board 13) in sequence in a direction away from the housing 21. Not only is the overall size of the compressor 2 reduced, but the compactness and stability of its internal structure are also improved. The terminal 26 of the stator assembly 24 is directly connected to the bus copper bar 121, which reduces the number of electrical connection points and reduces the risk of electrical failure. At the same time, since the electronic control component 1 is firmly installed in the electronic control cavity 23 formed by the housing 21 and the cover plate 22, it can more effectively prevent the electrical connection from being damaged by vibration or external force.

[0047] A plurality of pins 111 are provided on one side of the power device 11 in the thickness direction, and the compressor 2 can electrically connect the power device 11 with the electric control board 13 through the pins 111. A bus 12 is provided on one side of the power device 11 in the thickness direction, that is, the bus 12 is located at the top of the power device 11, and a first hole 123 is provided on the bus 12, and the first hole 123 is suitable for the pin 111 of the power device 11 to pass through. During assembly, the electric control board 13 is arranged on the side of the bus 12 away from the power device 11, and the pin 111 passes through the first hole 123 and cooperates with the electric control board 13 to realize the electrical connection between the power device 11 and the electric control board 13, thereby ensuring the reliability and stability of the internal electrical connection of the electric control component 1 and reducing the failure rate caused by poor electrical connection. A bus copper bus 121 electrically connected to the electric control board 13 is arranged in the bus 12. At the same time, a second hole 124 penetrating to the bus copper bus 121 is arranged on the bus 12. The second hole 124 is spaced apart from the first hole 123. The second hole 124 can be understood as a process hole on the bus 12, such as some positioning holes or other types of holes, which are convenient for processing and assembly of the bus 12. The power device 11, the bus 12 and the electric control board 13 are stacked in sequence in the thickness direction to form a compact structure, which helps to reduce the overall size of the electric control component 1, makes the electric control component 1 easier to integrate into the compressor 2, and further helps to reduce the volume and weight of the compressor 2.

[0048] The surface of the bus 12 is provided with a protruding first rib 141, which is located between the first hole 123 and the second hole 124. The provision of the first rib 141 effectively increases the creepage distance between the first hole 123 and the second hole 124. In a humid or condensing environment, even if water vapor or condensed water may appear on the surface of the bus 12, the first rib 141 can prevent the water vapor from directly connecting the pin 111 in the first hole 123 and the bus copper bar 121 in the second hole 124, thereby reducing the risk of short circuit caused by water vapor, ensuring that the electrical connection inside the electric control component 1 is safe and reliable, and avoiding the burning of the power device 11 or the failure and damage of the compressor 2 due to electrical faults. In addition, the first rib 141 can not only serve as an electrical isolation barrier, but also may enhance the structural strength of the bus 12 to a certain extent, which helps to improve the overall durability and reliability of the compressor 2.

[0049] According to one embodiment of the present invention, the bus copper busbar 121 is constructed in multiples, the second holes 124 are constructed in multiple groups corresponding to the bus copper busbar 121, and the multiple second holes 124 arranged at intervals in the extension direction of the corresponding bus copper busbar 121 are constructed as a group, and the extension direction of the first partition rib 141 is arranged parallel to the extension direction of the busbar 12 and is located on one side of a group of second holes 124. The compressor 2 is provided with multiple bus copper busbars 121, which can more effectively distribute and conduct current. Each bus copper busbar 121 is responsible for the transmission of a part of the current, which can reduce the current load on a single copper busbar, reduce resistance and heat generation, and improve the efficiency of current transmission. At the same time, the provision of multiple bus copper busbars 121 not only contributes to the uniform distribution of current, but also increases the heat dissipation area. Since the copper busbar is a good conductor of heat, multiple copper busbars can better disperse and conduct the generated heat, thereby improving the heat dissipation performance of the entire compressor 2 and extending the service life. The second holes 124 are process holes on the busbar, such as weight-reducing holes or positioning holes. The arrangement of multiple groups of second holes 124 can improve the assembly efficiency and lightweight of the busbar during processing and assembly. The extension direction of the first partition rib 141 is arranged parallel to the extension direction of the busbar 12 and is located on one side of a group of second holes 124, which not only maintains the compactness of the structure, but also optimizes the space utilization, so that all components can be effectively arranged in a limited space, while maintaining good current transmission and heat dissipation performance, and at the same time ensures that a first partition rib 141 is arranged between a second hole 124 and a first hole 123 adjacent to each other, which can effectively isolate the electrical appliances.

[0050] According to one embodiment of the present invention, the busbar 12 is respectively formed with second holes 124 that penetrate to the busbar copper busbar 121 on both sides in the thickness direction, and the first partition ribs 141 are respectively arranged on both sides of the busbar 12 in the thickness direction. The second hole 124 is a process hole on the busbar 12, and the setting of the process hole facilitates various process operations on the busbar 12 during the manufacturing process, such as electroplating, cleaning, and testing. These holes can be used as channels for fluids (such as electroplating liquids and cleaning agents) to ensure that the process can be carried out evenly and thoroughly, thereby improving product quality and production efficiency. At the same time, the process holes can also be used as positioning holes or inspection holes in the assembly process, which helps to simplify the assembly process and reduce production costs. The setting of the first partition rib 141 not only ensures electrical isolation, but also helps to enhance the structural strength and stability of the busbar 12. The first partition rib 141 is arranged on both sides of the busbar 12 in the thickness direction, and can serve as a supporting structure to prevent the busbar 12 from being deformed or damaged when subjected to external forces.

[0051] According to one embodiment of the present invention, the cross section of the first partition rib 141 in the extension direction is configured as a polygon or the edge of the first partition rib 141 away from the bus 12 is configured as an arc edge. The provision of the first partition rib 141 increases the creepage distance between the first hole 123 and the second hole 124, and at the same time, the condensed water or water vapor on the bus 12 short-circuits the pin 111 in the first hole 123 and the bus copper bar 121 in the second hole 124, thereby improving the electrical isolation effect of the bus 12. In actual processing, the shape of the first partition rib 141 can be reasonably designed to further extend the creepage distance between the first hole 123 and the second hole 124. For example, the cross section of the first partition rib 141 (the cross section here refers to the cross section in the extension direction of the first partition rib 141) can be a polygon, such as a triangle, a quadrilateral, etc., or a special figure with an arc edge on the top. The first partition rib 141 designed in this way can further increase the creepage distance between the first hole 123 and the second hole 124 and improve the electrical isolation effect.

[0052] In addition, the shape design of the first partition rib 141 also has a certain influence on the structural strength of the bus 12. When the cross-section of the first partition rib 141 is a polygon, such as a rectangle, a trapezoid or a hexagon, its structural strength is improved compared to a circle or an ellipse. The polygonal first partition rib 141 can better resist forces from different directions, thereby enhancing the overall structural strength and stability of the compressor 2. The design of the arc edge can reduce stress concentration to a certain extent, improve the fatigue resistance of the first partition rib 141, and extend the service life of the compressor 2.

[0053] According to an embodiment of the present invention, the shortest straight-line distance between the first hole 123 and the second hole 124 is D, the height of the first rib 141 is H, and the following conditions are satisfied: H-0.5D≥k, k satisfies: 1mm≤k≤2mm. Figure 3 As shown, the first hole 123 and the second hole 124 are both constructed in multiple forms. In order to ensure electrical isolation on the bus 12, it is necessary to ensure that a first partition rib 141 is also provided between the first hole 123 and the second hole 124 that are closest to each other. The function of the first partition rib 141 is to prevent condensed water or water vapor generated on the bus 12 from directly electrically connecting the first hole 123 and the second hole 124. Therefore, the first partition rib 141 needs to have a certain height. For the first holes 123 and the second holes 124 at different distances, the height of the first partition rib 141 can be varied to avoid the first partition rib 141 between the first holes 123 and the second holes 124 that are far apart being too high and resulting in a waste of material costs, or the first partition rib 141 between the first holes 123 and the second holes 124 that are close to each other being too low and unable to provide sufficient electrical isolation effect. Specifically, the shortest straight-line distance between the first hole 123 and the second hole 124 is D, the height of the first partition 141 is H, and satisfies: H-0.5D≥k, 1mm≤k≤2mm, where the value of K can be preferably 1.75mm, H-0.5D≥1.75mm, and the height H of the first partition 141 directly affects the creepage distance between the first hole 123 and the second hole 124. As the shortest straight-line distance D between the first hole 123 and the second hole 124 increases, the height H of the first partition 141 can be reduced accordingly. While ensuring sufficient creepage distance, the amount of the first partition 141 can be appropriately reduced to avoid unnecessary cost waste. The setting of the first partition 141H can ensure that the first partition 141 can provide sufficient electrical isolation effect in compressors 2 of different sizes.

[0054] It should be noted that no matter how D changes, H must be greater than or equal to 0.

[0055] According to one embodiment of the present invention, the diameter of the second hole 124 is d and satisfies: d≤1.5 mm. By limiting the diameter d of the second hole 124 (i.e., d≤1.5 mm), the risk of electrical leakage caused by excessive pores inside the electric control component 1 can be reduced, and the electrical isolation effect can be improved. At the same time, a smaller pore size also helps to reduce the possibility of impurities such as water vapor and dust entering the inside of the electric control component 1, thereby improving the reliability and durability of the compressor 2.

[0056] According to one embodiment of the present invention, the shortest distance between two adjacent second holes 124 is L and satisfies: L≥3.5mm. The setting of the shortest straight-line distance L between two adjacent second holes 124 (i.e., L≥3.5mm) helps to maintain the integrity of the internal structure of the compressor 2. A larger hole spacing can reduce the structural weakening caused by too dense holes and improve the shock and vibration resistance of the compressor 2.

[0057] According to one embodiment of the present invention, a copper bar 1211 connected to the bus copper bar 121 is formed on the bus 12, and the copper bar 1211 extends in the thickness direction of the bus 12 and is connected to the electric control board 13. The surface of the bus 12 is formed with an insulating protrusion 125 covering the root of the copper bar 1211. The copper bar 1211 extends in the thickness direction of the bus 12 and is connected to the electric control board 13. This design can ensure the stability and reliability of the electrical connection. The insulating protrusion 125 formed on the surface of the bus 12 covers the root of the copper bar 1211, which can prevent the water vapor or condensed water on the bus 12 from contacting the copper bar 1211, and prevent the risk of electrical short circuit and leakage. The insulating protrusion 125 provides an additional electrical isolation layer, which can ensure the safe operation of the compressor 2 even in harsh working environments.

[0058] According to one embodiment of the present invention, at least one first partition rib 141 is formed with a disconnection notch 1411, and the insulating protrusion 125 is arranged in the disconnection notch 1411 and is located between the first hole 123 and the second hole 124. By forming the disconnection notch 1411 on the first partition rib 141 and arranging the insulating protrusion 125 at the notch, the layout of the structure of the electric control component 1 can be arranged more flexibly, which helps to reduce the interference between the structures and improve the stability and reliability of the overall circuit. The insulating protrusion 125 is located in the disconnection notch 1411 and between the first hole 123 and the second hole 124, so that the insulating protrusion 125 can also serve as a structure for electrical isolation between the first hole 123 and the second hole 124, further enhancing the safety of the area.

[0059] According to one embodiment of the present invention, the pins 111 are configured as a plurality of pins arranged at intervals in the first direction, the first holes 123 are configured as a plurality of pins arranged in one-to-one correspondence with the corresponding pins 111, and the end of the first hole 123 facing the power device 11 is formed with a flared section 1231 whose aperture gradually increases in the direction of the power device 11. The design of the plurality of pins 111 and the corresponding first holes 123 helps to disperse the current, reduce the heat accumulation and electrical loss caused by the current concentration, improve the electrical efficiency of the compressor 2, and also help to extend its service life. Since the pins 111 and the holes are arranged one-to-one and at intervals, it is easier to align and fix the various components during the assembly and maintenance process, reducing assembly errors and maintenance time, and improving work efficiency. The design of the flared section 1231 enables the pin 111 to pass through the entrance of the hole more easily when inserted into the first hole 123, simplifies the assembly efficiency of the pin 111 and the busbar 12, and can also reduce the collision damage of the pin 111 when it is inserted into the first hole 123, thereby improving the safety of the compressor 2.

[0060] According to one embodiment of the present invention, the height of the first partition rib 141 of the busbar 12 on the side facing the power device 11 is not less than the first partition rib 141 on the side of the busbar 12 facing away from the power device 11. Since the flared section 1231 is provided on the side of the busbar 12 facing the power device 11, the distance between the first hole 123 and the second hole 124 on the side of the busbar 12 facing the power device 11 is closer, thereby appropriately increasing the height of the first partition rib 141 on the side of the busbar 12 facing the power device 11 (i.e., the size of the first partition rib 141 in the thickness direction of the busbar 12), ensuring that there is enough creepage distance between the first hole 123 and the second hole 124, thereby ensuring the electrical isolation effect.

[0061] According to one embodiment of the present invention, the first partition rib 141 is constructed as an annular rib that surrounds at least part of the outer periphery of the first hole 123. Different from the strip-shaped first partition rib 141 located between the first hole 123 and the second hole 124 in the above-mentioned embodiment, the first partition rib 141 can also be directly constructed as an annular rib that surrounds the first hole 123. The setting of the annular rib can also ensure that the first partition rib 141 exists between the first hole 123 and the second hole 124. The design of the annular rib provides an all-round electrical isolation barrier for the first hole 123. Compared with the simple strip-shaped or dot-shaped first partition rib 141, the annular rib can more effectively improve the electrical isolation effect and reduce the risk of electrical short circuit. The design of the annular rib not only has practical functions, but also can improve the appearance of the electric control component 1.

[0062] According to one embodiment of the present invention, a second partition rib 142 is provided between at least two adjacent second holes 124. The second partition rib 142 is provided between the first hole 123 and the second hole 124 to enhance the electrical isolation effect. Similarly, as shown in the figure, the second partition rib 142 can also be provided between two adjacent second holes 124, which can enhance the electrical isolation effect and increase the structural strength of the busbar.

[0063] According to one embodiment of the present invention, the busbar 12 includes an insulating layer 122, which is coated on at least part of the outer surface of the copper busbar 12, and a first hole 123 and a second hole 124 are formed on the insulating layer 122, and the first partition rib 141 and the second partition rib 142 are respectively formed integrally with the insulating layer 122. The setting of the insulating layer 122 provides the necessary electrical isolation for the copper busbar 12, and effectively prevents the risk of current leakage or short circuit. By forming the first hole 123 and the second hole 124, as well as the first partition rib 141 and the second partition rib 142 on the insulating layer 122, the processing and assembly process of the compressor 2 can be simplified, so that the pins 111, the wires and other components can be connected to the busbar 12 more easily and accurately, thereby improving the assembly efficiency and accuracy. The one-piece design makes it possible for there to be no seams or connection points between the first partition rib 141 and the second partition rib 142 and the insulating layer 122, thereby enhancing the strength and stability of the overall structure, helping the busbar 12 to resist external impact and vibration, and preventing the structure from loosening or deforming. At the same time, the one-piece design can ensure that there is no gap between the first barrier rib 141 or the second barrier rib 142 and the insulating layer 122 of the busbar 12 , further improving the electrical isolation effect of the first barrier rib 141 and the second barrier rib 142 .

[0064] In some embodiments, the electric control assembly 1 further includes: a mounting plate 15 and an insulating plate 16. The mounting plate 15 is arranged on the side of the power device 11 away from the bus 12, and the mounting plate 15 is suitable for connecting to the housing 21 of the compressor 2; the insulating plate 16 is arranged between the power device 11 and the mounting plate 15. The design of the mounting plate 15 provides a stable installation foundation for the power device 11. The mounting plate 15 can firmly fix the power device 11 on the housing 21 of the compressor 2 to prevent loosening or damage caused by vibration or external force, which helps to improve the stability and reliability of the electric control assembly 1. The setting of the insulating plate 16 provides the necessary electrical isolation between the power device 11 and the mounting plate 15, which can prevent the risk of current leakage or short circuit and ensure the safe operation of the compressor 2.

[0065] The vehicle according to the present invention will be briefly described below.

[0066] The vehicle according to the present invention includes the compressor 2 in the above embodiment. Since the vehicle according to the present invention is provided with the compressor 2 in the above embodiment, the compressor 2 reduces the volume of the compressor 2 by optimizing the structure and layout of the electronic control component 1, which is beneficial to the layout of the entire vehicle. The electronic control component 1 can ensure the electrical isolation effect through the first isolation rib 141, so that the operation of the compressor 2 is more stable, thereby ensuring the stability and safety of the vehicle during operation.

[0067] In summary, the compressor 2 is provided with a shell 21 and a cover plate 22, a motor cavity is formed in the shell 21, the shell 21, the cover plate 22 and the electric control cavity 23, a stator assembly 24 and a rotating shaft 25 cooperating with the stator assembly 24 are arranged in the motor cavity, an electric control assembly 1 is arranged in the electric control cavity 23, the electric control assembly 1 includes an electric control board 13, a bus 12 and a power device 11, a mounting plate 15 and an insulating plate 16, and the compressor 2 arranges the electric control assembly 1 and the stator assembly 24 in two cavities respectively, which can avoid interference during assembly of various components. The power device 11 is provided with a pin 111 connected to the electric control board 13, and the busbar 12 is provided with a first hole 123 suitable for the pin 111 to pass through and a second hole 124 used for the assembly process. During assembly, the pin 111 of the power device 11 passes through the first hole 123 and cooperates with the electric control board 13, thereby realizing the electrical connection between the power device 11 and the electric control board 13; the busbar 12 is provided with a busbar copper bus 121 and an insulating layer 122 covering at least part of the outer surface of the busbar copper bus 121, and a copper strip 1211 electrically connected to the electric control board 13 is formed on the busbar copper bus 121, and the first hole 123 penetrates the insulating layer 122 and connects to the busbar copper bus 121. The copper busbar 121 is spaced apart to facilitate the passage of the pin 111, and the second hole 124 extends to the surface of the busbar 121 (it can also be understood that the second hole 124 also penetrates the insulating layer 122, but the busbar 121 separates the second hole 124). A first barrier rib 141 is provided between the first hole 123 and the second hole 124. The first barrier rib 141 can increase the creepage distance between the first hole 123 and the second hole 124, and prevent the condensed water or water vapor generated on the busbar 12 from short-circuiting the pin 111 in the first hole 123 and the busbar 121 in the second hole 124, thereby improving the electrical isolation effect of the electric control component 1. During processing, the cross section of the first barrier rib 141 in the extension direction can be constructed as a polygon or a complex figure with an arc-shaped edge on the top, so as to further increase the creepage distance between the first hole 123 and the second hole 124. In addition, the first barrier rib 141 can also be constructed as an annular rib surrounding the first hole 123. After the copper strip 1211 passes through the insulating layer 122, it is connected to the electric control board 13. An insulating protrusion 125 covering at least part of the outer periphery of the copper strip 1211 can be provided on the insulating layer 122. For the convenience of layout, a disconnection notch 1411 can be provided at the position of the insulating protrusion 125 of the first partition 141. The insulating protrusion 125 is located in the disconnection notch 1411, which also has an electrical isolation effect. During processing, a flared section 1231 is formed at the end of the first hole 123 facing the power device 11. The flared section 1231 facilitates the pin 111 to pass through, thereby improving the assembly efficiency of the power device 11 and the bus 12. Since the second holes 124 are distributed at different positions on the surface of the bus 12, a second partition rib 142 can be provided between two second holes 124 that are relatively close to each other. An insulating plate 16 and a mounting plate 15 are provided in sequence on the side of the power device 11 away from the busbar, which are used to provide electrical isolation and facilitate the assembly of the electric control component 1 and the compressor 2, respectively.The electric control assembly 1 is disposed in an electric control chamber 23 formed by a housing 21 and a cover plate 22 of the compressor 2, so that the overall structure of the compressor 2 is more compact and convenient for vehicle layout.
