However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order presented herein; rather, changes that will be apparent upon understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity. The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application. Throughout this specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. Conversely, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between. As used herein, the term "and / or" includes any one of the relevant items listed and any combination of any two or more of them. Although terms such as "first," "second," and "third" may be used herein to describe individual components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. More precisely, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as such in the examples may also be referred to as the second component, assembly, region, layer, or part. For ease of description, spatial relational terms such as “above,” “upper,” “below,” and “lower” may be used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relational terms are intended to include not only the orientation depicted in the drawings but also the different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element.Therefore, the term "above" includes both "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., oscillating 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly. The terminology used herein is for describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "comprising," "including," and "having" enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible as will be apparent upon understanding the disclosure of this application.

[0024] Example 1 Addressing the technical challenges of existing electric drive integration methods for new energy commercial vehicles, such as numerous components, large and heavy electric drive assemblies, difficulties in vehicle layout, complex internal and external structures, and cumbersome assembly processes, this application provides an electric drive assembly, which will be discussed below. Figures 1-5 This electric drive assembly is described in detail.

[0025] Combination Figures 1-5 As shown, the electric drive assembly includes a housing section, which is an integral structure rather than a split structure, and surrounds a sealed mounting cavity. This sealed mounting cavity is divided into a first mounting area, a second mounting area, a third mounting area, and a fourth mounting area. The first and second mounting areas are spaced apart in a first direction 105, the fourth and third mounting areas are spaced apart in the first direction 105, the first and fourth mounting areas are spaced apart in a second direction 106, and the second and third mounting areas are spaced apart in the second direction 106. In other words, the housing section as a whole has a roughly rectangular structure. The integrated structure of the housing section offers higher integration and easier installation compared to a split structure. Furthermore, the integrated housing design is manufactured using a one-piece molding process, avoiding the complexity of separate placement and wiring required in a split structure.

[0026] It should be noted that, with Figure 1 Taking the directions shown in the figure as an example, the first direction 105 refers to the vertical upward direction, and the second direction 106 refers to the horizontal leftward direction.

[0027] Specifically, it still combines Figure 5 As shown, the cover includes a housing 101, a first end cap 107, and a second end cap 108; wherein, the housing 101 has a main body 102 and an extension, and a first mounting area is formed in the main body 102; optionally, two extensions are provided, namely a first extension 103 and a second extension 104, the first extension 103 extends from the main body 102 along a first direction 105, and the second extension extends from the main body 102 along a second direction 106.

[0028] Furthermore, the housing 101 includes a main body 109, a front cover 110, and a rear cover 111; the main body 109 is similar in shape to the motor module 2, both being cylindrical; the front cover 110 is disposed at one end of the main body 109 along its axial direction; the rear cover 111 is disposed at the other end of the main body 109 along its axial direction, and the rear cover 111, the main body 109, and the front cover 110 enclose a first mounting area.

[0029] Optionally, the front cover 110 and the main body 109, and the rear cover 111 and the main body 109 are both connected by bolts. Using bolts ensures the reliability and durability of the connection, facilitates installation, and allows for detachable connections for the main body 109, front cover 110, and rear cover 111. When maintenance is needed on components within the first installation area, disassembly is convenient; simply removing the bolts allows separation of the main body 109, front cover 110, and rear cover 111.

[0030] In practical use, considering that bolts are prone to loosening under vibration, rubber pads can be placed at the bolt connection to increase the friction coefficient at the bolt connection, thereby improving the connection's firmness.

[0031] Among them, combined Figure 1 and Figure 5 As shown, the first end cap 107 is fastened to the first extension 103, and a second mounting area is formed between the end cap 107 and the first extension 103. Optionally, the first end cap 107 is fixed to the first extension 103 with bolts. Similarly, the bolted connection allows for a detachable connection between the first extension 103 and the first end cap 107, facilitating disassembly when maintenance is required on components within the second mounting area; simply removing the bolts separates the first extension 103 and the first end cap 107. Preferably, the first end cap 107 is a plate-like structure with reinforcing ribs, which improve the strength of the first end cap 107.

[0032] Among them, still combined Figure 1 and Figure 5As shown, the second end cap is fastened to the second extension 104, and a fourth mounting area and a third mounting area are arranged at intervals along the first direction 105 between the end cap and the second extension 104. Optionally, the second end cap 108 is fixed to the second extension 104 with bolts. Similarly, the bolted connection method enables a detachable connection between the second extension 104 and the second end cap 108, facilitating disassembly when maintenance is required on components in the third and fourth mounting areas; simply removing the bolts allows separation of the second extension 104 and the second end cap 108. Preferably, the second end cap 108 is a plate-like structure with reinforcing ribs, which improve the strength of the second end cap 108.

[0033] Combination Figures 1-5 As shown, the electric drive assembly includes a motor module 2, which is fixedly mounted in the first mounting area. Preferably, the motor module 2 includes a motor. During actual installation, the rigidity requirements of the motor installation must be considered to ensure that the motor's performance does not degrade or become damaged due to vibration or uneven stress during operation.

[0034] Combination Figures 1-5 As shown, the electric drive assembly includes a motor controller module 3, which is fixedly installed in the second installation area and electrically connected to the motor module 2 through a first connector, so as to realize the start-stop, speed and other control of the motor through the motor controller module 3.

[0035] Optionally, the motor controller module 3 includes a controller, preferably a PLC controller. It is worth noting that this application does not make any structural or program improvements to the controller itself.

[0036] Optionally, the first connector is a three-phase terminal block copper busbar 113, through which the motor controller module 3 is electrically connected to the copper busbar of the motor module 2. Here, the three-phase terminal block copper busbar 113 serves as the first connector, acting as a bridge connecting the motor controller and the motor. It is typically made of copper with high conductivity and is responsible for transmitting the three-phase AC power output from the controller to the motor. Furthermore, the three-phase terminal block copper busbar 113 is bolted to the housing 101.

[0037] Combination Figures 1-5 As shown, the electric drive assembly also includes a power controller module 4 and a high-voltage power distribution module 5. The power controller module 4 is fixedly installed in the third mounting area. The high-voltage power distribution module 5 is fixedly installed in the fourth mounting area.

[0038] The high-voltage power distribution module 5 is electrically connected to the motor controller module 3 via a second connector 501. Optionally, the second connector 501 is a first wiring harness 112, meaning the high-voltage power distribution module 5 is electrically connected to the motor controller module 3 via the first wiring harness 112. Since the motor controller module 3 requires power from the high-voltage power distribution module 5 (but is not involved in control), the first wiring harness 112 is used to achieve the connection between the two. The first wiring harness 112 offers greater flexibility than a rigid connection, facilitating wiring in limited spaces and making it easier to disassemble and reassemble during maintenance or replacement. Furthermore, compared to a customized rigid connection, the mass production cost of the first wiring harness 112 is lower.

[0039] The high-voltage power distribution module 5 is also electrically connected to the power controller module 4 via the third connector 502.

[0040] Optionally, the third connector 502 includes a second wiring harness 114 and a filter copper busbar 115, and the high-voltage power distribution module 5 is electrically connected to the power controller module 4 through the second wiring harness 114 and the filter copper busbar 115 respectively.

[0041] The above-mentioned use of the second wiring harness 114 realizes the current transmission between the high-voltage power distribution module 5 and the power controller module 4. The second wiring harness 114 itself has flexible wiring and is easy to install in complex spaces.

[0042] The aforementioned copper busbar filter 115 is used to achieve signal propagation between the high-voltage power distribution module 5 and the power controller module 4. The copper busbar filter 115 also suppresses electromagnetic interference, ensuring the signal stability of the power controller module 4 and the system reliability.

[0043] In this embodiment, combined with Figure 1 As shown, multiple power holes 116 are provided on the main body 109 at positions corresponding to the high-voltage power distribution module 5 along the first direction 105; the wiring harness of the external power supply is electrically connected to the high-voltage power distribution module 5 through the power holes 116.

[0044] The aforementioned power port 116 provides a channel for external power harnesses to enter the enclosure, serving as a physical interface for power transmission. The design of multiple power ports 116 supports multiple power inputs, improving the system's power supply reliability.

[0045] Optionally, four power supply holes 116 are provided, arranged at intervals along a vertically upward direction. The power supply holes 116 are located along the first direction 105, ensuring their layout aligns with the main structural direction of the enclosure. This helps optimize internal space utilization and makes the wiring harness arrangement neater and more orderly.

[0046] In this embodiment, combined with Figure 1As shown, the electric drive assembly includes a water-cooled heat dissipation unit 6, which includes a water inlet pipe 601, a heat dissipation pipe, a transfer pipe 602, and a condenser 603. The water inlet pipe 601 is disposed on the second extension 104 and can be connected to an external water source, that is, the external water source is introduced into the enclosure through the water inlet pipe 601.

[0047] The heat dissipation pipes are formed on the first end cover 107 and the second end cover 108, respectively. To improve the heat dissipation effect, the heat dissipation pipes can be arranged in a serpentine pattern on the first end cover 107 and the second end cover 108. It should be noted that the heat dissipation pipes are not additional pipes, but are directly formed on the first end cover 107 and the second end cover 108. They can be understood as being formed by directly opening holes in the first end cover 107 and the second end cover 108.

[0048] The water inlet hole of the heat dissipation pipe on the second end cover 108 is connected to the water inlet pipe 601. This means that when external water flows through the water inlet pipe 601, it will be directly guided to the heat dissipation pipe on the second end cover 108, thereby realizing heat exchange between the high voltage power distribution module 5 and the power controller module 4.

[0049] One end of the transfer pipe 602 is connected to the water outlet of the heat dissipation pipe on the second end cover 108, and the other end is connected to the water inlet of the heat dissipation pipe on the first end cover 107. In other words, after the cooling water completes the heat exchange of the high voltage power distribution module 5 and the power controller module 4, it is guided through the transfer pipe 602 to the heat dissipation pipe on the first end cover 107, thereby exchanging heat with the motor controller module 3.

[0050] The water inlet of the condenser 603 is connected to the water outlet of the heat dissipation pipe on the first end cover 107. That is, after the cooling water completes the heat exchange of the motor controller module 3, it passes through the condenser 603 and is connected to the external water source.

[0051] In this embodiment, the electric drive assembly includes an oil cooling heat dissipation unit 7, which includes an oil reservoir, stator oil cooling pipes, rotor oil cooling pipes, and a main pipeline 701. The oil reservoir is located at a preset position in the first installation area (optionally, the first preset position is below the motor) and is used to store cooling oil. The oil reservoir is connected to the oil inlet of the condenser 603 and can guide the cooling oil to the condenser 603. In other words, when the cooling oil is guided to the condenser 603, the condenser 603 can exchange heat and cool the cooling oil.

[0052] The stator oil cooling pipe surrounds the stator of motor module 2 and is connected to the oil reservoir. The rotor oil cooling pipe surrounds the rotor of motor module 2 and is connected to the oil reservoir. The main pipe 701 is connected to the oil outlet of the condenser 603; the cooling oil that has undergone heat exchange in the condenser 603 is connected to the stator oil cooling pipe and the rotor oil cooling pipe respectively through the main pipe 701. The actual cooling process is as follows: First, cooling oil is supplied to the oil reservoir through the oil filling hole; then, the cooling oil passes through the condenser 603, where it undergoes refrigeration and heat exchange; then, the refrigerated and heat-exchanged cooling oil is guided through the main pipe 701 to the enclosure, where it is supplied to the stator oil cooling pipe and the rotor oil cooling pipe respectively, thereby achieving heat dissipation for the motor stator and rotor; finally, the heat-exchanged cooling oil flows to the oil reservoir, which then guides the cooling oil with a higher temperature back to the condenser 603 for refrigeration.

[0053] In summary, compared to the prior art where each module is covered by an independent housing 101, this application integrates multiple modules into an integrated housing 101, reducing the number of housings 101 and thus reducing the total weight of the electric drive assembly. Furthermore, the reduced overall mass of the electric drive assembly improves the efficiency of the electric drive operation.

[0054] In addition, during installation, each module only needs to be placed in its corresponding installation area, and then the first end cover 107 and the second end cover 108 are fastened onto the housing 101 to complete the assembly. From a process perspective, this reduces the number of production steps and greatly improves assembly efficiency.

[0055] Example 2 This application also provides a vehicle including the aforementioned electric drive assembly. Therefore, it possesses all the beneficial effects of an electric drive assembly, which will not be specifically elaborated upon here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
