[0027] Please refer to Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of an electric drive assembly of an integrated compressor provided by the present application. In one aspect of the present application, an electric drive assembly 10 of an integrated compressor is provided, the electric drive assembly 10 comprises an integrated housing 1, a master controller 2, a drive motor 3, a compressor 4, a motor harness 5, a compressor harness 6 and a reducer 7; a first accommodating area 11, a second accommodating area 12, a third accommodating area 13 and a fourth accommodating area 14 separated from each other are provided in the integrated housing 1. Specifically, the first accommodating area 11, the second accommodating area 12 and the third accommodating area are stacked along the first direction D1, the fourth accommodating area 14 is arranged side by side with the second accommodating area 12 along the second direction D2, and the first direction D1 and the second direction D2 intersect; the master controller 2, the drive motor 3 and the compressor 4 are arranged in the first accommodating area 11, the second accommodating area 12 and the third accommodating area 13 respectively; the motor harness 5 is arranged in the integrated housing 1 and connects the drive motor 3 and the master controller 2; the compressor harness 6 is arranged in the integrated housing 1 and connects the compressor 4 and the master controller 2; the reducer 7 is arranged in the fourth accommodating area 14, and the reducer 7 is connected to the drive motor 3. Through the above structure, the electric drive assembly 10 of the present application can integrate the compressor 4, the motor, the master controller 2 and the reducer 7 in an integrated housing 1, thereby reducing the parts used for connection, reducing weight, reducing volume, and facilitating the layout of the whole vehicle, and the motor harness 5 and the compressor harness 6 are also integrated in the integrated housing 1, which can protect the connection of the harness and improve the reliability of the harness connection.

[0028] In order to reduce the volume of the compressor 4 so that the compressor 4 can be installed in the third accommodating area 13, the electric drive assembly 10 of the embodiment of the present application connects the master controller 2 with the compressor 4 through the compressor harness 6, so that the compressor 4 can be controlled by the master controller 2, so that the compressor 4 can reduce the volume of a controller, thereby realizing the integration of the compressor 4 and the electric drive assembly 10 in one housing. By integrating the compressor 4 in this way, the brackets or bolts used for connection and the housing of the compressor 4 and other parts can be omitted, thereby reducing the weight of the electric drive assembly 10 after integration and reducing costs.

[0029] The motor harness 5 and the compressor harness 6 are both integrated in the integrated housing 1, which can avoid external influences or damage to the harness connection, and can improve the reliability of the harness connection. When in use, the main controller 2 can control the drive motor 3 to work according to the motor harness 5, and the drive motor 3 can drive the reducer 7 to work. The main controller 2 can also control the compressor 4 through the compressor harness 6. In other words, the main controller 2 can control the drive motor 3 and the compressor 4 respectively through the motor harness 5 and the compressor harness 6. On the one hand, the compressor controller 22 originally set on the compressor 4 can be omitted to reduce the volume of the compressor 4. On the other hand, centralized control can be achieved. The motor harness 5 and the compressor harness 6 are both connected to the main controller 2, which can play a role in constraining the harness, reduce the length required for the harness connection, improve the reliability of the harness connection, and achieve cost reduction and efficiency improvement.

[0030] Furthermore, the first accommodating area 11, the second accommodating area 12, the third accommodating area 13 and the fourth accommodating area 14 are integrated together, which can increase the rigidity of the integrated shell 1 and reduce the vibration of the electric drive assembly 10 during operation, thereby improving the NVH performance Noise, Vibration, Harshness, noise, vibration and acoustic roughness of the electric drive assembly 10.

[0031] In one embodiment of this application, please continue to combine Figure 2 and Figure 3 , Figure 2 yes Figure 1 The structural diagram of the first accommodating area in FIG. Figure 3 yes Figure 1 The integrated housing 1 includes a housing portion 15 and two partition plates 16; the housing portion 15 includes a supporting partition plate 151 and two first shell plates 152, the supporting partition plate 151 extends along a first direction D1; the two first shell plates 152 are respectively connected to the supporting partition plate 151 and are located on the same side of the supporting partition plate 151; the partition plates 16 are arranged between the first shell plates 152 at intervals, and each partition plate 16 is connected to the supporting partition plate 151; the first accommodating area 11, the second accommodating area 12 and the third accommodating area 13 are formed between the two partition plates 16 and between each partition plate 16 and the corresponding first shell plate 152.

[0032] Specifically, the supporting partition 151 can separate the shell 15 into two parts, one of which can be separated into the first accommodating area 11, the second accommodating area 12 and the third accommodating area 13 along the first direction D1 by the partition plate 16 and the first shell plate 152. The other part can be used to form the fourth accommodating area 14.

[0033] In one embodiment of the present application, along the first direction D1, the second accommodation area 12 is located between the first accommodation area 11 and the third accommodation area 13. The master controller 2, the drive motor 3 and the compressor 4 are arranged in the first accommodation area 11, the second accommodation area 12 and the third accommodation area 13 in sequence.

[0034] Specifically, the two first shell plates 152 and the two partition plates 16 are arranged in the order of the first shell plate 152, the partition plate 16, the partition plate 16 and the first shell plate 152 along the first direction D1. That is, along the first direction D1, the first accommodating area 11 and the third accommodating area 13 are formed between the first shell plate 152 and the corresponding partition plate 16, and the second accommodating area 12 is formed between the two partition plates 16.

[0035] Furthermore, in the first accommodation area 11 of the master controller 2, such an arrangement can facilitate the connection and arrangement of the wire harness. The motor wire harness 5 and the compressor wire harness 6 can extend from the master controller 2 along the first direction D1 and respectively connect the drive motor 3 located in the second accommodation area 12 and the compressor 4 located in the third accommodation area 13, so that the wire harness can be arranged in an orderly manner in the integrated housing 1, improving or avoiding confusion and crossing of the wire harness arrangement, and improving the reliability of the wire harness connection.

[0036] In one embodiment of the present application, the integrated shell 1 also includes a first sealing plate 17, which connects one of the partition plates 16 and a first outer shell plate 152. The first sealing plate 17, the partition plate 16, the first outer shell plate 152 and the supporting partition plate 151 surround the first accommodating area 11 to form a box structure; the first sealing plate 17 is provided with a wiring harness through hole, through which the power supply wiring harness 5 and the compressor wiring harness 6 pass.

[0037] Specifically, the first accommodating area 11 formed by the first shell plate 152, the partition plate 16 and the supporting partition plate 151 has an opening in the second direction D2, and the first sealing plate 17 can connect the corresponding partition plate 16 and the first shell plate 152 and cover the opening, thereby forming a box structure of the sealing plate, which plays a role in protecting the master controller 2. In order to facilitate the electrical connection between the master controller 2 and the drive motor 3 and the compressor 4, a harness through hole can be set on the first sealing plate 17 to facilitate the passage of the motor harness 5 and the compressor harness 6, so as to realize the control of the drive motor 3 and the compressor 4 by the master controller 2.

[0038] Furthermore, the wiring harness through hole may include a first through hole and a second through hole, the first through hole is used for the power supply wiring harness 5 to pass through, and the second through hole is used for the compressor wiring harness 6 to pass through. In this way, the wiring harnesses can be classified and organized to improve the neatness of the wiring harness connection; it can also play the role of fixing the wiring harness and improve the reliability of the wiring harness connection.

[0039] In one embodiment of the present application, the shell portion 15 also includes two second shell plates 153, which are respectively connected to the supporting partitions 151 and are located on the other side of the supporting partitions 151 facing away from the first shell plate 152; the integrated shell 1 also includes a second sealing plate 18, which is connected to the second shell plate 153, and the second sealing plate 18, the supporting partition 151 and the second shell plate 153 together form a fourth accommodating area 14.

[0040] Specifically, the second shell plate 153 extends along the second direction D2, and the second sealing plate 18 is connected to one end of the second shell plate 153 facing away from the supporting partition 151, so that the second sealing plate 18, the supporting partition 151 and the corresponding two second shell plates 153 can enclose the fourth accommodating area 14. The fourth accommodating area 14 is adjacent to the first accommodating area 11, the second accommodating area 12 and the third accommodating area 13, and there is only one supporting partition 151 in the middle. Through such a setting, on the one hand, the four accommodating areas can be integrated together to improve the rigidity of the integrated shell 1, thereby improving the NVH performance; on the other hand, it is also convenient to integrate the reducer 7, the main controller 2, the drive motor 3 and the compressor 4 together, reduce the overall volume of the electric drive assembly 10, and provide convenience for the layout of the whole vehicle.

[0041] Furthermore, along the first direction D1, the two partition plates 16 can be located between the two second outer shell plates 153, so that the fourth accommodating area 14 can be arranged side by side with the second accommodating area 12, thereby reducing the straight-line distance between the reducer 7 and the drive motor 3, so as to facilitate the connection between the reducer 7 and the drive motor 3 and improve the efficiency of the drive motor 3 in driving the reducer 7 to work.

[0042] In one embodiment of the present application, a mounting hole is provided on the support partition 151; the driving motor 3 includes a driving shaft 31, and the reducer 7 includes an input gear 71, and the driving shaft 31 and the input gear 71 are drivingly connected.

[0043] Specifically, the drive shaft 31 can pass through the mounting hole and be driven and connected to the input gear 71. When the electric drive assembly 10 is running, the drive shaft 31 can drive the input gear 71 to rotate together, thereby driving the reducer 7 to work. The whole process is highly efficient and reliable.

[0044] In one embodiment of the present application, the electric drive assembly 10 also includes a differential 8 accommodated in the fourth accommodating area 14; the reducer 7 also includes an output gear 72; the output gear 72 and the differential 8 are drivingly connected; the electric drive assembly 10 also includes an output shaft 9, and the two output shafts 9 are respectively arranged on opposite sides of the differential 8 and are drivingly connected to the differential 8.

[0045] Specifically, in addition to the input gear 71 and the output gear 72, the reducer 7 also includes an intermediate gear 73 for transmitting kinetic energy. The input gear 71 and the output gear 72 are arranged in sequence along the first direction D1, and the intermediate gear 73 is located between the input gear 71 and the output gear 72. The kinetic energy on the input gear 71 can be transmitted to the output gear 72 through the intermediate gear 73, thereby driving the differential 8 to rotate. It should be noted that in addition to being connected to the differential 8, the two output shafts 9 are also connected to the wheels 20. The rotation of the differential 8 can drive the output shafts 9 to rotate, thereby outputting kinetic energy to the wheels 20.

[0046] In a specific embodiment, the intermediate gear 73 includes an intermediate pinion 732 and an intermediate large gear 731 which are synchronously fixed, the intermediate pinion 732 meshes with the output gear 72, and the intermediate large gear 731 meshes with the input gear 71, so that the drive shaft 31 drives the input gear 71 to rotate, the input gear 71 drives the intermediate large gear 731 and the intermediate pinion 732 to rotate, and then the intermediate pinion 732 drives the output gear 72 to rotate, the output gear 72 drives the differential 8 to rotate, and finally the kinetic energy is transmitted to the wheel 20 along the output shaft 9 through the differential 8, so that the wheel 20 rotates. In another specific embodiment, since the positional arrangements of the differential 8, the input gear 71 and the output gear 72 are different, the intermediate gear 73 may also include other structures, such as two synchronously fixed large gears or pinions, etc., which will not be described in detail here.

[0047] In one embodiment of the present application, the integrated shell 1 also includes a third sealing plate 19, which is connected to the first outer shell plate 152, and the third sealing plate 19 and the first outer shell plate 152 together form a wiring harness installation channel; the motor wiring harness 5 and the compressor wiring harness 6 are both connected to the drive motor 3 and the compressor 4 respectively from the main controller 2 along the wiring harness installation channel.

[0048] Specifically, in order to protect the wiring harness connection from external influences and improve the reliability of the wiring harness connection, the motor wiring harness 5 and the compressor wiring harness 6 can be arranged in the wiring harness installation channel to improve or avoid the situation where the wiring harness is exposed.

[0049] In one embodiment of the present application, the motor wiring harness 5 includes a low-voltage wiring harness 51 and a high-voltage wiring harness 52; the main controller 2 includes a motor controller 21 and a compressor controller 22, and the low-voltage wiring harness 51 and the high-voltage wiring harness 52 are both connected to the drive motor 3 and the motor controller 21; the compressor wiring harness 6 connects the compressor 4 and the compressor controller 22.

[0050] Specifically, the motor controller 21 and the compressor controller 22 are integrated in the first accommodating area 11, which can reduce the parts and structures used to connect and install the compressor controller 22, thereby reducing costs. Along the first direction D1, the compressor controller 22 and the motor controller 21 are arranged in sequence, so that the motor controller 21 is connected to the drive motor 3 and the compressor controller 22 is connected to the compressor 4.

[0051] Furthermore, both the low-voltage harness 51 and the high-voltage harness 52 can be connected to the drive motor 3 along the harness installation channel, thereby improving or avoiding the situation where the harness is messy and intertwined, and improving the reliability of the harness connection. The drive motor 3 also includes a motor rotor 32, which is drivingly connected to the drive shaft 31. When in use, the low-voltage harness 51 can transmit the signal of the drive motor 3 to the motor controller 21, and the motor controller 21 can control the drive motor 3 to work through the high-voltage harness 52 according to the signal, so that the motor rotor 32 rotates, and then drives the drive shaft 31 to rotate, thereby driving the reducer 7 and the differential 8 to work.

[0052] The compressor controller 22 can also control the operation of the compressor 4 through the compressor wiring harness 6. Specifically, Figure 4 As shown, Figure 4 yes Figure 1 The compressor 4 includes a compressor motor 41 and a scroll 42, and the compressor motor 41 is drivingly connected to the scroll 42. Figure 1 and Figure 4 Since the compressor controller 22 is integrated with the motor controller 21, the compressor controller 22 can share a power supply with the motor controller 21. That is to say, the compressor harness 6 can not only provide power to the compressor 4, but also be used to transmit signals to the compressor 4, so that the compressor controller 22 controls the operation of the compressor 4, thereby saving additional harnesses and reducing costs. When in use, the compressor controller 22 can control the rotation of the compressor motor 41 through the compressor harness 6, and the compressor motor 41 then drives the vortex 42 to rotate, thereby realizing the operation of the compressor 4.

[0053] Please combine Figure 1 and Figure 5 , Figure 5It is a structural schematic diagram of another embodiment of the electric drive assembly of the integrated compressor of the present application. In another embodiment of the present application, different from the above-mentioned embodiment, the integrated shell 1 includes a box body, a shell portion 15 and a partition plate 16. Along the third direction D3, the shell portion 15 is connected to the box body and is located below the box body. The first accommodating area 11 is located in the box body. The partition plate 16 is arc-shaped and is connected and fixed to the box body. The partition plate 16 encloses the second accommodating area 12. The shell portion 15 includes a first shell plate 152, a supporting partition plate 151 and a second shell plate 153. The first shell plate 152 encloses the third accommodating area 13 and is connected to the box body through the supporting partition plate 151. The second shell plate 153 is connected to the box body and encloses the fourth accommodating area 14. Along the third direction D3, the first accommodating area 11 is located above the second accommodating area 12. Along the first direction D1, the second accommodating area 12 and the third accommodating area 13 are arranged in sequence. Along the second direction D2, the fourth accommodating area 14 is arranged side by side with the second accommodating area 12. The third direction D3 intersects with the second direction D2 and the first direction D1.

[0054] The master controller 2, the drive motor 3, the compressor 4 and the reducer 7 are sequentially arranged in the first accommodating area 11, the second accommodating area 12, the third accommodating area 13 and the fourth accommodating area 14. By opening a harness through hole on the box body, the motor harness 5 and the compressor harness 6 can pass through the harness through hole to connect the drive motor 3 and the compressor 4 respectively.

[0055] Through the above structure, it is also possible to integrate the compressor 4, the drive motor 3, the main controller 2 and the reducer 7 in one housing, and separate the mechanical structure of the compressor 4 from the compressor controller 22, thereby reducing the volume of the electric drive assembly 10, reducing weight and reducing costs.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted. In addition, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product of the present application is usually placed when used, which is only for the convenience of describing the embodiments of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application.
