Detailed Implementation

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] The first aspect of this application provides a power system, as shown in Figures 1, 2, and 3. The power system includes a housing 1, a motor 2, a control module 3, a transmission mechanism 4, and a conductive component 5. The housing 1 has a drive chamber 101, a transmission chamber 102, and a control chamber 103.

[0039] A portion of the motor 2 is located inside the drive chamber 101.

[0040] The transmission mechanism 4 is located inside the transmission chamber 102.

[0041] Control module 3 is located in control room 103.

[0042] Motor 2 is connected to transmission mechanism 4.

[0043] The conductive element 5 extends into the control chamber 103 and is electrically connected to the control module 3, and the conductive element 5 also extends into the transmission chamber 102 and is electrically connected to the motor 2.

[0044] Understandably, the housing 1 provides support for the motor 2, control module 3, and transmission mechanism 4. The control module 3 is electrically connected to the motor 2 via a conductive element 5, and can control the operating parameters of the motor 2 to output appropriate power and transmit it to the transmission mechanism 4. The conductive element 5 is located in the control chamber 103 and the transmission chamber 102, which on the one hand realizes the electrical connection between the motor 2 and the control module 3, and on the other hand improves the space utilization efficiency of the power system of this application, thereby improving its compactness and reducing the space occupied.

[0045] In this embodiment, at least a portion of the motor 2 is located inside the drive chamber 101, which helps to reduce the size of the power system of this application.

[0046] Specifically, when one part of the motor 2 is located inside the drive chamber 101, the other part is located outside the drive chamber 101. Therefore, the housing 1 does not need to completely enclose the motor 2. Compared with the case of complete enclosure, the part of the motor 2 exposed outside the drive chamber 101 lacks the wall surface of the drive chamber 101, thus occupying less space in this direction, which is beneficial to reducing the volume of the housing 1.

[0047] In this embodiment of the application, the part of the motor 2 opposite to its output end can be located outside the drive chamber 101.

[0048] In this embodiment of the application, the motor 2 can be connected to the wall of the drive chamber 101 by bolts.

[0049] In this embodiment of the application, the drive chamber 101 may include two sub-chambers, which are separated by reinforcing ribs, and each sub-chamber is equipped with a motor 2.

[0050] In this embodiment, since the various components of the transmission mechanism 4 generally rotate during operation, the transmission mechanism 4 is located in the transmission chamber 102, which can be protected by the housing 1 on the one hand, and is also conducive to the recovery of lubricating oil for lubrication and cooling of the transmission mechanism 4 on the other hand.

[0051] In this embodiment, the transmission mechanism 4 can be stably positioned within the transmission chamber 102 by being supported by the motor 2 through the portion that forms a transmission connection with the motor 2.

[0052] The motor 2 may include a rotor shaft that extends into the transmission chamber 102. The transmission mechanism 4 includes a gear that is fitted around the rotor shaft and is connected to the rotor shaft via a key or other means to achieve transmission, thus enabling the motor 2 to support the transmission mechanism 4. Optionally, the wall of the transmission chamber 102 has a groove in which a bearing can be arranged. The rotor shaft passes through the bearing and is supported by the bearing.

[0053] In this embodiment, the motor 2 may include a first body and a second body, which are respectively connected to the transmission mechanism 4 for transmission. The first body can receive power through the transmission mechanism 4, and the second body can be used to transmit power to the transmission mechanism 4.

[0054] In this embodiment, the control module 3 is located inside the control room 103, which is beneficial for the control module 3 to be close to the motor 2, thereby improving the reliability of the electrical connection between the two.

[0055] Understandably, the fact that both the control module 3 and the motor 2 are located inside the housing 1 helps to shorten the length of the conductive part 5 that electrically connects them. A shorter conductive part 5 has lower resistance and also makes it easier for assembly personnel to observe and assemble the conductive part 5.

[0056] In this embodiment, since the conductive element 5 extends into the transmission chamber 102 and is electrically connected to the motor 2, it occupies less space in the control chamber 103 and does not occupy space in the drive chamber 101. The drive chamber 101 does not need to allocate additional space for the conductive element 5. Furthermore, since electrical components are generally not installed in the transmission chamber 102, the conductive element 5, located within the transmission chamber 102, provides a certain degree of stability and does not occupy vehicle space. In addition, the transmission mechanism 4 requires a certain amount of space during operation, and therefore generally maintains a certain distance from the wall of the transmission chamber 102. This distance allows for the arrangement of the conductive element 5, thereby improving the space utilization efficiency of the transmission chamber 102 and reducing the volume of the power system in this application, thus minimizing its impact on vehicle space.

[0057] In this embodiment, the control module 3 can be connected to the wall of the control room 103 by bolts.

[0058] In this embodiment, the conductive element 5 extends into the control chamber 103 and is electrically connected to the control module 3, and the conductive element 5 also extends into the transmission chamber 102 and is electrically connected to the motor 2.

[0059] In this embodiment of the application, the opening of the drive chamber 101 and the opening of the transmission chamber 102 are located on opposite sides of the housing 1.

[0060] In this embodiment, the housing 1 can be integrally formed by casting or other methods to form a drive chamber 101, a transmission chamber 102, and a control chamber 103.

[0061] In this embodiment, the control module 3 can be an ECU (Electronic Control Unit).

[0062] In this embodiment, the conductive element 5 may be made of a conductive metal such as copper to achieve an electrical connection between the motor 2 and the control module 3. The conductive element 5 can be used to transmit current and voltage to the motor 2 to control the operation of the motor 2.

[0063] In this embodiment, the control module 3 can control the output power, speed, and start / stop of the motor 2 through the conductive element 5.

[0064] In this embodiment, the control chamber 103 and the drive chamber 101 are relatively enclosed. That is, the control module 3 of the control chamber 103 is blocked by the housing 1 and cannot directly contact the motor 2 of the drive chamber 101. Correspondingly, the motor 2 of the drive chamber 101 is also blocked by the housing 1 and cannot directly contact the control module 3 of the control chamber 103.

[0065] In this embodiment, the power system includes a cover, and the control chamber 103 has an opening for the control module 3 to be inserted. The opening can be sealed by the cover, thus reducing the possibility of the control module 3 being contaminated by impurities and short-circuiting. The cover and the opening of the control chamber 103 can be connected by bolts to form a seal.

[0066] In this embodiment, the transmission mechanism 4 includes a reduction shaft, a gear, and a differential. The reduction shaft is connected to the motor drive, the gear is sleeved on the reduction shaft and connected to the reduction shaft drive, and the gear also meshes with the differential, thus realizing the power transmission to the motor.

[0067] In this embodiment, the opening of the transmission chamber 102 and the opening of the drive chamber 101 face opposite sides of the housing 1, which facilitates the assembly of the motor 2 and the transmission mechanism 3 into the drive chamber 101 and the transmission chamber 102, respectively.

[0068] In some embodiments of this application, as shown in FIG3, the drive chamber 101 and the transmission chamber 102 are located on the same side of the control chamber 103.

[0069] It is understandable that the drive chamber 101 and the transmission chamber 102 are located on the same side of the control chamber 103, which is conducive to the drive chamber 101 and the control chamber 103 being adjacent in position. This is beneficial for the motor 2 to directly extend into the transmission chamber 102 and be connected to the transmission mechanism 4.

[0070] In some embodiments of this application, as shown in Figures 2 and 3, the orthographic projections of the control chamber 103 and the transmission chamber 102 on the first projection plane at least partially overlap, and the orthographic projections of the control chamber 103 and the drive chamber 101 on the first projection plane at least partially overlap. The first projection plane is a plane perpendicular to the height direction of the housing 1. The height direction of the housing 1 is shown in Figure 2.

[0071] Understandably, this arrangement allows the conductive component 5 to extend directly from the control chamber 103 into the transmission chamber 102, ensuring that the conductive component 5 is completely located inside the housing 1 and protected by the housing 1. This not only facilitates the electrical connection between the conductive component 5 and the motor 2 and the control module 3, but also shortens the length of the electrical connection between the conductive component 5 and the motor 2 and the control module 3.

[0072] In this embodiment, the power system further includes a lubrication mechanism for lubricating the transmission mechanism 4 and the conductive component 5. The lubrication mechanism may include an oil pump connected to the transmission chamber 102 to spray lubricating oil into the transmission chamber 102.

[0073] In some embodiments of this application, as shown in FIG2, at least a portion of the conductive element 5 is located above the transmission mechanism 4, and the orthographic projection of the conductive element 5 on the first projection plane is located in the portion where the orthographic projection of the control chamber 103 and the orthographic projection of the transmission chamber 102 coincide.

[0074] It is understandable that the conductive component 5 can extend directly into the transmission chamber 102 from the part where the orthographic projection of the transmission chamber 102 coincides with the orthographic projection of the control chamber 103, which is beneficial for realizing the electrical connection between the control module 3 and the motor 2.

[0075] In addition, the conductive component 5 located above the transmission mechanism 4 can reduce the possibility of collision with the transmission mechanism 4. At the same time, the lubricating oil that lubricates the conductive component 5 can also come into contact with the transmission mechanism 4 under the action of gravity, improving the lubrication efficiency and preventing the conductive component 5 from being immersed in the lubricating oil for a long time.

[0076] In some embodiments of this application, as shown in Figures 1, 2, and 3, the housing 1 has a first connecting hole 104, which extends along the height direction of the housing 1 and connects the control chamber 103 and the transmission chamber 102. The conductive element 5 extends into the transmission chamber 102 through the first connecting hole 104. The height direction of the housing 1 is shown in Figure 2.

[0077] Understandably, the first connecting hole 104 connects the control chamber 103 and the transmission chamber 102, allowing the conductive component 5 to pass through, which facilitates the electrical connection of the conductive component 5 to the control module 3 and the motor 2. The first connecting hole 104, which extends along the height direction of the housing 1, helps to shorten the length of the conductive component 5 that passes through, thereby improving the electrical connection performance of the conductive component 5.

[0078] In this embodiment, the first connecting hole 104 can be formed by drilling after casting the shell 1.

[0079] In some embodiments of this application, as shown in FIG5, the conductive element 5 includes a sealing part 53, a first connecting part 51 and a second connecting part 52. The sealing part 53 connects the first connecting part 51 and the second connecting part 52, and the sealing part 53 seals the first communicating hole 104. The first connecting part 51 is located in the control chamber 103, and the second connecting part 52 is located in the transmission chamber 102.

[0080] Understandably, the first connecting part 51 is located in the control chamber 103 and can form an electrical connection with the control module 3. The second connecting part 52 is located in the transmission chamber 102 and can form an electrical connection with the motor 2. The sealing part 53 can seal the first connecting hole 104, which on the one hand can reduce the lubricating oil in the transmission chamber 102 from entering the control chamber 103 through the first connecting hole 104 and contaminating the control module 3 and causing a short circuit in the control module 3, and on the other hand can also generate friction by contacting the wall of the first connecting hole 104, thereby supporting the conductive component 5.

[0081] In this embodiment, the sealing part 53 and the first connecting hole 104 can be connected and sealed by threads. Specifically, the sealing part 53 has an external thread that extends helically along the extending direction of the first connecting hole 104, and the wall surface of the first connecting hole 104 has an internal thread that matches the external thread. The two engage to form a seal. The gap between the wall surface of the first connecting hole 104 and the sealing part 53 can be filled to improve its sealing performance.

[0082] In this embodiment, the first connecting part 51 can be electrically connected to the control module 3 by means of plugging or other methods. Specifically, the control module 3 has an interface, and the first connecting part 51 is inserted into the interface to form a plug-in and electrical connection with the control module 3.

[0083] In this embodiment, the second connecting part 52 is electrically connected to the wire of the motor 2 by means of bolt fastening or welding. The number of second connecting parts 52 can be one, two, three, or more.

[0084] In this embodiment, the cross-sectional area of ​​the first sealing part 53 is greater than the cross-sectional area of ​​the first connecting part 51 and greater than the cross-sectional area of ​​the second connecting part 52.

[0085] Understandably, since there are generally multiple second connecting parts 52, and the current generated by a single second connecting part 52 is small, but the current generated by all the second connecting parts 52 needs to be collected in the first sealing part 53 and pass through the first connecting part 51, the current passing through the first sealing part 53 is relatively large during operation. Therefore, setting the cross-sectional area of ​​the first sealing part 53 to be larger than the cross-sectional area of ​​the first connecting part 51 and larger than the cross-sectional area of ​​the second connecting part 52 is beneficial to reducing the internal resistance of the first sealing part 53. The reduced internal resistance of the first sealing part 53 can prevent the second connecting part 52 from generating too much heat and melting due to excessive current, thus improving the operational safety of the conductive component 5.

[0086] In some embodiments of this application, the orthographic projection of the conductive element 5 onto the second projection plane partially coincides with the orthographic projection of the motor 2 onto the second projection plane, and the second projection plane is a plane perpendicular to the width direction of the housing 1. The width direction of the housing 1 is shown in Figure 2.

[0087] Understandably, this arrangement improves the structural compactness of the power system of this application, which is beneficial to reducing the size of the power system. Specifically, the orthographic projection of the conductive element 5 on the second projection plane coincides with the orthographic projection of the motor 2 on the second projection plane. On the one hand, this allows the conductive element 5 to be closer to the motor 2, which is beneficial to forming an electrical connection between the conductive element 5 and the motor 2. On the other hand, the overlapping part means that the motor 2, the conductive element 5, and the control module 3 are not arranged sequentially in the height direction of the housing 1, but rather the motor 2 and the conductive element 5 are both located below the control module 3. Therefore, the housing 1 is shortened in the height direction, which reduces the height of the power system of this application and thus reduces its size.

[0088] In this embodiment of the application, as shown in Figures 6 and 7, the power system includes a cover plate 6, and the control room has a window 107. The cover plate 6 can seal the window 107. The portion of the conductive element 5 extending into the control room 103 has its orthographic projection on the second projection plane coincides with the orthographic projection portion of the window 107 on the second projection plane. The conductive element 5 is closer to the window 107 than the control module 3. This facilitates the assembly personnel to connect the conductive element 5 and the control module 3 through the window 107. After connecting the conductive element 5 and the control module 3, the cover plate 6 can be used to seal the window 107, reducing the possibility of contamination of the control module 3 and the conductive element 5.

[0089] Optionally, the conductive component 5 and the control module 3 can be connected by bolts.

[0090] Optionally, window 107 is located on the side of control room 103 adjacent to transmission room 102.

[0091] Optionally, the cover plate 6 and the housing 1 can be connected by bolts to form a sealing surface around the window 107, thereby sealing the window 107.

[0092] In some embodiments of this application, as shown in FIG4, the housing 1 has a second connecting hole 105, which extends along the width direction of the housing 1 and connects the drive chamber 101 and the transmission chamber 102. The motor 2 is electrically connected to the conductive element 5 through the second connecting hole 105.

[0093] It is understandable that the second connecting hole 105 provides a channel for the motor 2 to electrically connect to the conductive component 5, which is beneficial for the motor 2 to form an electrical connection with the conductive component 5 in the transmission chamber 102.

[0094] In some embodiments of this application, as shown in FIG4, the housing 1 has a third connecting hole 106, which extends along the width direction of the housing 1 and connects the drive chamber 101 and the transmission chamber 102. The motor 2 is connected to the transmission mechanism 4 via the third connecting hole 106. The third connecting hole 106 and the second connecting hole 105 are located on the same side of the housing 1.

[0095] Understandably, the third connecting hole 106 allows the motor 2 to pass through and connect with the transmission mechanism 4, while also providing support for the motor 2 and the transmission mechanism 4. The third connecting hole 106 and the second connecting hole 105 are located on the same side of the housing 1, concentrating the weight of the motor 2 and the transmission mechanism 4 on the wall of the drive chamber 101. This facilitates the direct transmission of axial and lateral torques of the transmission mechanism 4 to the housing 1, thereby improving the modal characteristics of the power system and enhancing its NVH (Noise, Vibration and Harshness) performance.

[0096] A second aspect of this application provides an automobile that includes a power system as described in the above embodiments.

[0097] It is understood that, due to the use of the power system of the above embodiments, the automobile of this application has the same technical effects as the above embodiments, and will not be described again here.

[0098] In the embodiments of this application, the vehicle can be an electric vehicle or a hybrid vehicle.

[0099] In this embodiment of the application, the automobile may include an engine, and the motor 2 includes a first body and a second body. The engine and the first body are connected by a transmission mechanism, so that the power generated by the engine can be transmitted to the first body through the transmission mechanism 4. The first body is driven by the power and can generate electrical energy to power the second body.
