Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0030] The directional terms used in the embodiments of this application, such as "up," "down," and "side," are generally based on the relative positions shown in Figure 1. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute positions. When the product is placed in different orientations, the positions may change; for example, "up" and "down" may be interchanged.

[0031] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0032] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0033] The first aspect of this application provides a power device, as shown in Figures 1 and 2, comprising a housing 3, a first motor 1, a second motor 2, a conductive element 5, and a controller 4.

[0034] The first motor 1 and the second motor 2 are both located inside the housing 3 and are arranged at intervals along the width direction of the housing 3.

[0035] The controller 4 is located inside the housing 3, and the controller 4 is located above the first motor 1 and the second motor 2 along the height direction of the housing 3.

[0036] The controller 4, the first motor 1, and the second motor 2 form a gap of 100.

[0037] The conductive element 5 is located within the gap 100 and is electrically connected to the controller 4 and the first motor 1, as well as electrically connected to the controller 4 and the second motor 2.

[0038] Understandably, the housing 3 provides support for the first motor 1, the second motor 2, the conductive element 5, and the controller 4. The controller 4 controls the operating status of the first motor 1 and the second motor 2 via the conductive element 5. At least a portion of the conductive element 5 is located between the first motor 1 and the second motor 2, which can improve the space utilization efficiency of the power unit of this application, thereby improving the compactness of the power unit of this application and reducing its space occupation.

[0039] In this embodiment, the structures of the first motor 1, the second motor 2, and the controller 4 are generally fixed. Furthermore, since they are designed to perform their functions, their spatial layout is generally limited. Therefore, when the controller 4 is positioned above the first motor 1 and the second motor 2, a large gap 100 is often formed between them to avoid interference. This gap 100 results in the power unit occupying a significant amount of space. On the other hand, the controller 4 needs to transmit electrical signals to the first motor 1 and the second motor 2 via conductive components 5 to control them. However, the conductive components 5 are generally located outside the housing 3, which not only makes them susceptible to damage but also occupies considerable space.

[0040] By arranging the conductive element 5 within the gap 100 formed by the first motor 1, the second motor 2, and the controller 4, this application not only helps to protect the conductive element 5 and maintain its normal operation, but also improves the compactness of the power device of this application, thus reducing the space occupied.

[0041] In this embodiment, the housing 3 serves as a structure supporting the first motor 1, the second motor 2, and the controller 4. It can be manufactured using an integral molding process or as a separate structure, with different parts supporting the first motor 1, the second motor 2, and the controller 4 respectively, and then connected to form the structure.

[0042] In the embodiments of this application, the first motor 1 can function as a generator to generate electricity, or it can function as a power source to transmit power to other structures of the vehicle.

[0043] In the embodiments of this application, the second motor 2 can function as a generator to generate electricity, or it can function as a power source to transmit power to other structures of the vehicle.

[0044] In this embodiment, the conductive element 5 can be a copper busbar or an aluminum busbar. The material of the conductive element 5 can be a conductive metal such as copper or aluminum, or an alloy containing a conductive metal.

[0045] In this embodiment of the application, the controller 4 can be an MCU (Motor Control Unit).

[0046] In this embodiment, both the first motor 1 and the second motor 2 are located within the housing 3 and are spaced apart along the width direction of the housing 3. This arrangement along the width direction means that the output ends of the first motor 1 and the second motor 2 are parallel, which reduces interference between the first motor 1 and the second motor 2 and facilitates power transmission between them and other components. The gap 100 may include the interval formed by the first motor 1 and the second motor 2 along the width direction of the housing 3.

[0047] In this embodiment, a gap 100 is formed between the controller 4, the first motor 1, and the second motor 2. This gap 100 can be formed by connecting the controller 4, the first motor 1, and the second motor 2 to the housing 3, respectively, to fix their positions. In this embodiment, the gap 100 may include the area enclosed by the area below the controller 4, the side of the first motor 1 near the second motor 2, and the side of the second motor 2 near the first motor 1.

[0048] In this embodiment, the conductive element 5 is located within the gap 100 and is electrically connected to the controller 4 and the first motor 1, as well as electrically connected to the controller 4 and the second motor 2. The conductive element 5 can be fixed in position by being electrically connected to the first motor 1, the second motor 2, and the controller 4 respectively. The conductive element 5 can also be electrically connected by bolts to wires leading from the first motor 1, the second motor 2, and the controller 4, thus maintaining its relatively fixed position. Alternatively, the conductive element 5 can be held within the gap 100 by the support formed by the housing 3. The conductive element 5 and the housing 3 can be connected by bolts.

[0049] In some embodiments of this application, the first motor 1, the second motor 2, and the controller 4 are easily damaged by contamination, and therefore all require a relatively enclosed space to operate. As shown in Figure 3, the housing 3 includes a first sub-housing 31 and a second sub-housing 32. The first sub-housing 31 has a first receiving cavity 3101, and the second sub-housing 32 has a second receiving cavity 3201. The first sub-housing 31 and the second sub-housing 32 form a third receiving cavity 301. The conductive element 5 extends from the first receiving cavity 3101 through the third receiving cavity 301 into the second receiving cavity 3201, and relatively seals the first receiving cavity 3101 and the second receiving cavity 3201. This improves the sealing performance of the first motor 1, the second motor 2, and the controller 4.

[0050] It is understood that the first receiving cavity 3101 can accommodate the controller 4, and the second receiving cavity 3201 can accommodate the first motor 1 and the second motor 2. Since the first motor 1 and the second motor 2 have similar operating environment requirements, placing them in the second receiving cavity 3201 helps improve the compactness of the power device of this application. The third receiving cavity 301 formed by the first sub-shell 31 and the second sub-shell 32 facilitates the passage of the conductive element 5 to form electrical connections with the controller 4, the first motor 1, and the second motor 2 respectively. This allows the controller 4 to control the operating status of the first motor 1 and the second motor 2 through the conductive element 5. The conductive element 5 also relatively seals the first receiving cavity 3101 and the second receiving cavity 3201, which on the one hand reduces the possibility of contamination of the controller 4, the first motor 1, and the second motor 2, and on the other hand reduces the number of sealing components, simplifying the structural complexity of the power device of this application.

[0051] In this embodiment, the inlets of the first receiving cavity 3101 and the second receiving cavity 3201 are located on the upper and lower sides of the third receiving cavity 301, respectively, along the height direction of the housing 3. This facilitates the conductive element 5 to directly pass through the inlets of the first receiving cavity 3101 and the second receiving cavity 3201, and to connect with the controller 4, the first motor 1, and the second motor 2, respectively. The conductive element 5 can be threaded to the inlet of the first receiving cavity 3101 to form a seal, and can also abut against the first sub-housing 31 to form a seal on the first receiving cavity 3101. Similarly, the conductive element 5 can be threaded to the inlet of the second receiving cavity 3201 to form a seal, and can also abut against the second sub-housing 32 to form a seal on the second receiving cavity 3201.

[0052] In this embodiment, a portion of the second sub-shell 32 is recessed away from the first sub-shell 31, and the recessed portion and the first sub-shell 31 form a second receiving cavity 3201. At the same time, the recessed portion is located between the first motor 1 and the second motor 2. This is beneficial for the second sub-shell 32 to support the conductive element 5, preventing the conductive element 5 from protruding from the second sub-shell 32 and interfering with the first sub-shell 31. It also helps to improve the compactness of the power device of this application.

[0053] In the embodiments of this application, the third receiving cavity 301 partially overlaps with the gap 100, or the third receiving cavity 301 is located within the gap 100.

[0054] In some embodiments of this application, as shown in FIG3, a first sealing surface 33 is formed between the first sub-shell 31 and the second sub-shell 32, and the first sealing surface 33 extends circumferentially along the third receiving cavity 301.

[0055] Understandably, the first sealing surface 33 helps to improve the sealing performance of the portion of the conductive element 5 located in the third receiving cavity 301, thereby reducing the possibility of the conductive element 5 becoming contaminated and unable to maintain normal operation.

[0056] In this embodiment, the first sub-shell 31 and the second sub-shell 32 can be connected by bolts. The bolts extend in the height direction of the shell 3, which can refer to the arrangement direction of the first sub-shell 31 and the second sub-shell 32.

[0057] In this embodiment, the first sealing surface 33 may refer to the annular surface formed by the contact between the first sub-shell 31 and the second sub-shell 32. The annular first sealing surface 33 facilitates the installation of the conductive element 5 on the second sub-shell 32, and the contact between the first sub-shell 31 and the second sub-shell 32 allows the conductive element 5 to be located within the third receiving cavity 301.

[0058] In this embodiment, the first sealing surface 33 extends circumferentially along the third receiving cavity 301, which can mean that the first sealing surface 33 is perpendicular to the height direction of the housing 3.

[0059] In some embodiments of this application, as shown in FIG3, the conductive element 5 includes a first terminal 511, a connecting portion 512, and a second terminal 513. The connecting portion 512 connects the first terminal 511 and the second terminal 513. The first terminal 511 is connected to the controller 4, and the second terminal 513 is connected to the first motor 1 and the second motor 2 respectively.

[0060] Understandably, the first terminal 511 can be connected to the controller 4, and the second terminal 513 can be connected to the first motor 1 and the second motor 2. Since there are generally two or more first terminals 511 and second terminals 513, the connection part 512 can handle the current from multiple first terminals 511 and second terminals 513, which is beneficial for the controller 4 to control the first motor 1 and the second motor 2 through the conductive part 5.

[0061] In the embodiments of this application, the first terminal 511, the connecting portion 512, and the second terminal 513 can be formed by an integral molding process.

[0062] In this embodiment, the conductive element 5 may further include a first bolt and a second bolt. The first bolt passes through the first terminal 511 and can press the terminal from the controller 4 onto the first terminal 511, thus achieving connection with the controller 4. The second bolt passes through the second terminal 513 and can press the terminal from the first motor 1 and the terminal from the second motor 2 onto the second terminal 513, thus achieving connection with the first motor 1 and the second motor 2 respectively.

[0063] In some embodiments of this application, as shown in FIG3, the power unit includes a rear cover 6, which is connected to a second sub-shell 32 to form a second sealing surface 34. The second sealing surface 34 extends circumferentially along the opening of the second receiving cavity 3201. The conductive element 5 and the rear cover 6 are spaced apart along the length of the shell 3. The first terminal 511 is closer to the second sealing surface 34 than the second terminal 513.

[0064] Understandably, the opening of the second receiving cavity 3201 is due to the placement of the first motor 1 and the second motor 2 within it. The second sealing surface 34 formed by the rear cover 6 and the second sub-shell 32 improves the sealing performance of the second receiving cavity 3201. The second sealing surface 34 extends circumferentially along the opening of the second receiving cavity 3201, reducing the likelihood of impurities entering the interior of the second receiving cavity 3201 through the opening and contaminating the motors. The first terminal 511 is closer to the second sealing surface 34 than the second terminal 513, reducing the possibility of the second terminal 513 interfering with the structure connecting the rear cover 6 and the second sub-shell 32. This allows the rear cover 6 and the second sub-shell 32 to incorporate additional design elements to avoid the second terminal 513.

[0065] In this embodiment, the rear cover 6 and the second sub-shell 32 can be connected by a connector 7, which extends along the length of the shell 3. The orthographic projection of the connector 7 onto the projection plane coincides with the orthographic projection of the second terminal 513 onto the projection plane, which is a plane perpendicular to the length of the shell 3. The connector 7 can pass through the rear cover 6 and form a threaded connection with the second sub-shell 32, thus enabling the connection between the rear cover 6 and the second sub-shell 32.

[0066] In this embodiment, the second sealing surface 34 may be annular.

[0067] In this embodiment, at least a portion of the connecting portion 512 is attached to the second sub-shell 32 and forms a third sealing surface with the second sub-shell 32. The third sealing surface surrounds the entrance of the second receiving cavity 3201 and is located below the first sealing surface 33 along the height direction of the shell 3.

[0068] It is understandable that the first sealing surface 33 is formed by the connection of the first sub-shell 31 and the second sub-shell 32, and is therefore affected by the structure of the first sub-shell 31 and the second sub-shell 32. The third sealing surface is formed by the connection of the connecting part 512 and the second sub-shell 32, and is therefore affected by the structure of the connecting part 512 and the second sub-shell 32. The third sealing surface is located below the first sealing surface 33, which is beneficial because the overall height of the housing 3 is only affected by the first sub-shell 31 and the second sub-shell 32, thus helping to shorten the height of the power unit of this application.

[0069] In some embodiments of this application, as shown in FIG1, the first motor 1 is cylindrical, the second motor 2 is cylindrical, and the conductive element 5 is located between the side of the first motor 1 and the side of the second motor 2.

[0070] Understandably, for the cylindrical first motor 1 and second motor 2, the distance between them, from the center line extending along the width direction of the housing 3, increases as they approach the conductive element 5. This facilitates the placement of the conductive element 5 within the gap 100, thereby reducing interference to the first motor 1 and the second motor 2.

[0071] In some embodiments of this application, as shown in FIG2, the conductive element 5 has a first end 521 and a second end 522 along the width direction of the housing 3. The first end 521 and the output end of the first motor 1 form a first distance along the width direction of the housing 3, and the second end 522 and the output end of the second motor 2 form a second distance along the width direction of the housing 3. The first distance and the second distance are approximately equal.

[0072] Understandably, the first distance and the second distance can indicate the degree of interference of the conductive element 5 to the first motor 1 and the second motor 2. The smaller the first distance, the easier it is for the conductive element 5 to interfere with the first motor 1; the smaller the second distance, the easier it is for the conductive element 5 to interfere with the second motor 2. Having approximately equal first and second distances is beneficial for balancing the interference of the conductive element 5 to the first motor 1 and the second motor 2, and also for facilitating the placement of the conductive element 5 between the first motor 1 and the second motor 2.

[0073] In the embodiments of this application, due to assembly requirements and process limitations, the first distance and the second distance do not need to be exactly equal, and a 5% error is allowed between them.

[0074] In the embodiments of this application, the first distance can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm or 85mm, or other values ​​from 20 to 85mm.

[0075] In the embodiments of this application, the second distance can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm or 85mm, or other values ​​from 20 to 85mm.

[0076] In this embodiment of the application, the output end of the first motor 1 can refer to the center of the rotor shaft of the first motor 1.

[0077] In this embodiment of the application, the output end of the second motor 2 can refer to the center of the rotor shaft of the second motor 2.

[0078] In some embodiments of this application, as shown in FIG1, the width of the portion of the conductive element 5 located in the gap 100 is greater than the first distance.

[0079] It is understandable that a wider conductive element 5 is beneficial for connecting with the first motor 1 and the second motor 2 respectively, and can also improve the compactness of the power device of this application.

[0080] In the embodiments of this application, the width of the conductive element 5 can be 80mm, 85mm, 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm, 150mm, 155mm, 160mm, 165mm, 170mm, 175mm or 180mm, or other values ​​from 80 to 180mm.

[0081] In some embodiments of this application, the conductive element 5 includes a plurality of third terminals 514, which are located between the first motor 1 and the second motor 2 and arranged along the width of the conductive element 5. An electrical gap 51401 is formed between two adjacent third terminals 514, and each third terminal 514 is connected to one of the first motor 1 and the second motor 2.

[0082] It is understandable that the third terminal 514 can be connected to the first motor 1 and the second motor 2, which is beneficial for the controller 4 to control the first motor 1 and the second motor 2 through the conductive component 5.

[0083] In this embodiment, the width of the conductive element 5 may refer to the sum of the widths of all third terminals 514 and all electrical clearances 51401.
