Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a controller and powertrain. Background Technology

[0002] In the existing technology, controllers such as motor controllers, vehicle air conditioning controllers, and power controllers all have three-phase components. The three-phase component is the core component in the controller that realizes the transmission, conversion and distribution of electrical energy. The three-phase component completes the access, output or internal conversion of three-phase electricity through three conductive parts (usually copper busbars, cables or terminals) with a phase difference of 120° between them and the insulation structure, ensuring the safe operation of the power system.

[0003] The three-phase assembly includes three conductive components. To facilitate installation of these components onto the controller housing, each component is encased in a plastic shell with connecting protrusions. Multiple screws pass through these protrusions and connect to the controller housing, thus mounting the three-phase assembly onto the housing. Therefore, to install the conductors onto the controller housing, not only are plastic shells required, but multiple screws are also used, making the installation process relatively cumbersome. Utility Model Content

[0040] In existing technologies, controllers such as motor controllers, vehicle air conditioning controllers, and power controllers all have three-phase components. As a key component of the controller, the three-phase component is responsible for the transmission, conversion, and distribution of electrical energy. The three-phase component consists of three conductive components (commonly copper busbars, cables, or terminals) with a phase difference of 120° between them. These conductive components work together with the insulation structure to complete the input, output, and internal conversion operations of three-phase electricity, thereby ensuring the safe operation of the power system.

[0041] The three-phase module contains three conductive components. To facilitate installation of these components onto the controller housing, each component is encased in a plastic shell with connecting protrusions. During installation, multiple screws pass through these protrusions and connect to the controller housing, thus securing the three-phase module to the housing. This installation method not only requires the plastic shells on the conductive components but also the use of multiple screws, making the installation process rather cumbersome.

[0042] Based on the above-mentioned technical problems, this application provides a controller and a powertrain. The structure of the controller is described below with reference to the accompanying drawings.

[0043] Reference Figure 1 and Figure 2 As shown in the illustration, the controller in this embodiment includes a housing 100 and at least one conductor 200. The housing 100 has at least one mounting groove 110, and a connector 120 is provided on the housing 100 located on at least one side of the mounting groove 110. At least a portion of the conductor 200 is inserted into the mounting groove 110; the connector 120 is configured to connect to the conductor 200 and fix the conductor 200 to the mounting groove 110.

[0044] The controller and powertrain of this application embodiment have a mounting groove 110 provided on the housing 100, at least a portion of the conductor 200 is inserted into the mounting groove 110, and a connector 120 located on at least one side of the mounting groove 110 is provided on the housing 100 and connected to the conductor 200. This can fix the conductor 200 on the mounting groove 110, eliminating the need to provide a plastic shell for the conductor 200, thereby improving the assembly efficiency of the conductor 200 on the housing 100.

[0045] It should be noted that the controller in this application embodiment may be a motor controller, a vehicle air conditioning controller, a power controller, etc. The housing 100 with the mounting groove 110 is specifically a controller housing 100, which may be made of plastic material to facilitate the lightweighting of the controller.

[0046] In one possible implementation, the connector 120 and the conductor 200 are thermally riveted. This simplifies the installation steps of the conductor 200, thereby improving the assembly efficiency of the conductor 200. The connector 120 in its initial state is... Figure 4 As shown in the diagram, during the insertion of the conductor 200 into the mounting slot 110, the connector 120 acts as a barrier to the conductor 200, which facilitates the insertion of the conductor 200 into the mounting slot 110.

[0047] When connected, the connector 120 is attached to the conductor 200. At this time, the connector 120 is also block-shaped, and the connector 120 effectively blocks the opening of the corresponding area mounting groove 110, thereby preventing the conductor 200 from coming out of the mounting groove 110.

[0048] When performing a hot riveting operation on connector 120, the hot riveting equipment should control the heating temperature of connector 120 so that connector 120 melts and connects to conductor 200. It is important to note that the melting temperature of connector 120 should be lower than the melting temperature of conductor 200 to avoid damaging conductor 200 when connector 120 melts. In addition to hot riveting, connector 120 and conductor 200 can also be connected by riveting with rivets.

[0049] In this embodiment, the connector 120 and the housing 100 are integrally formed, both made of plastic. This not only facilitates the thermal riveting of the connector 120, but also improves processing efficiency, simplifies the assembly process, and ensures the connection strength between the connector 120 and the housing 100. Of course, the connector 120 can also be formed separately and then attached to the housing 100. In this case, the connection between the connector 120 and the conductor 200 also satisfies the installation requirements of the conductor 200.

[0050] In this embodiment, the conductor 200 has a connecting portion 230, and the connector 120 is thermally riveted to the connecting portion 230. The thermal riveting of the conductor 200 to the connector 120 via the connecting portion 230 facilitates determining the connection position between the conductor 200 and the connector 120, thereby improving connection accuracy.

[0051] In one possible implementation, such as Figure 5 and Figure 6 As shown, the connecting portion 230 includes a plurality of protrusions that extend along the extending direction of the conductor 200. This increases the contact area between the connector 120 and the connecting portion 230 during thermal riveting, thereby improving the connection strength.

[0052] Multiple raised strips are arranged along the thickness direction of the conductor 200, and the cross-section of each strip is triangular. This allows the multiple raised strips to mesh in a tooth-like manner. During the hot riveting of the connector 120, the molten connector 120 fills the gap between adjacent raised strips. After the connector 120 cools and solidifies, it forms a connecting surface that engages with the raised strips. This further enhances the connection strength between the connecting part 230 and the connector 120. It is understood that the shape and arrangement of the raised strip cross-sections can be adjusted according to usage requirements.

[0053] In another possible implementation, the connecting portion 230 includes multiple protrusions. The cross-section of the protrusions can be circular, triangular, polygonal, or other shapes. In this case, the cooperation between the multiple protrusions and the molten connecting member 120 also helps to improve the connection strength and reliability between the connecting member 120 and the connecting portion 230.

[0054] like Figure 4 As shown, the connector 120 has a guide surface 121 on the side facing away from the mounting groove 110. The guide surface 121 is inclined toward the mounting groove 110, and the cross-sectional area of ​​the connector 120 gradually decreases in the direction away from the housing 100. By providing the guide surface 121, the pressure head of the thermal riveting equipment can move along the guide surface 121 and apply pressure to the connector 120, making it easier for the connector 120 to fold toward the conductor 200 after being heated and connect with the conductor 200, thereby improving the thermal riveting efficiency between the connector 120 and the conductor 200.

[0055] In this embodiment, there are at least two connectors 120, with at least one connector 120 provided on each of the opposite sides of the mounting groove 110. This allows for connection to the conductor 200 via multiple connectors 120, improving the fixation of the conductor 200 on the mounting groove 110.

[0056] In one possible implementation, there are multiple connectors 120, and the connectors 120 on opposite sides of the mounting groove 110 are staggered in the extending direction of the mounting groove 110. This facilitates the arrangement of the connectors 120 and also improves the connection strength between the connectors 120 and the conductor 200.

[0057] In another possible implementation, at least two connectors 120 located on either side of the mounting groove 110 are arranged opposite each other. For example Figure 4 and Figure 5 As shown, two connectors 120 are provided on both sides of the mounting groove 110, and the two connectors 120 on both sides are correspondingly arranged. At this time, the two connectors 120 work together to connect and fix the conductor 200 at the same position, thereby further improving the connection strength with the conductor 200, and thus improving the installation reliability of the conductor 200.

[0058] It should be noted that, in the connected state, when the sum of the widths of the two connectors 120 after hot riveting is greater than or equal to the width of the corresponding mounting groove 110, the two connectors 120 are hot-riveted together. When the sum of the widths of the two connectors 120 after hot riveting is less than the width of the corresponding mounting groove 110, the two connectors 120 are spaced apart and not connected to each other. Of course, in specific implementations, the arrangement and number of connectors 120 can be determined according to requirements.

[0059] In one possible implementation, the conductor 200 is interference-fitted with the mounting groove 110, which facilitates the pre-installation of the conductor 200 in the mounting groove 110 and achieves positioning of the conductor 200 on the mounting groove 110. Furthermore, the interference fit between the conductor 200 and the mounting groove 110 also helps prevent the conductor 200 from tilting relative to the mounting groove 110, thereby further improving the connection stability of the conductor 200 on the housing 100.

[0060] In one possible implementation, such as Figures 6 to 8 As shown, the conductor 200 includes a first segment 210 and a second segment 220 connected to one end of the first segment 210. The first segment 210 is inserted into the mounting groove 110 and connected to the connector 120, while the second segment 220 is located outside the mounting groove 110. Here, the first segment 210 of the conductor 200 facilitates the installation of the conductor 200 in the mounting groove 110, while the second segment 220, located outside the mounting groove 110, facilitates the connection of the conductor 200 with other components.

[0061] like Figure 6 As shown, the second segment 220 includes a first part 211 and a second part 212 connected to one end of the first part 211. The end of the first part 211 away from the second part 212 is connected to the first segment 210. The first part 211 and the second segment 220 are integrally formed, while the second part 212 is formed separately. The first segment 210 is formed by connecting the first part 211 and the second part 212.

[0062] In terms of specific structure, the first part 211 and the second section 220 are sheet-like, and the two are connected in an "L" shape. The second part 212 has a sheet-like first end and a cylindrical second end, and the first end is used to connect with the first part 211. Corresponding to the second end, a through hole is provided at the bottom of the mounting groove 110, and the through hole facilitates the electrical connection between the second end and related components.

[0063] The first part 211 has a third end and a fourth end, wherein the third end is used to connect with the first end, and the fourth end is used to connect with the second part 220. For example... Figure 7As shown, the third end is provided with a connecting hole 2111, and the two opposite sides of the first end are respectively provided with flanges 2121. The third end of the first part 211 can be placed between the two flanges 2121 and abut against one side of the first end of the second part 212.

[0064] A connecting piece 240 is connected between the two flanges 2121. The two sides of the connecting piece 240 are connected to the corresponding flanges 2121 respectively. A connecting block 241 protruding into the connecting hole 2111 is provided in the middle of the connecting piece 240. The connecting block 241 is embedded in the connecting hole 2111, so that the first part 211 and the second part 212 are connected. In the connected state, the first part 211 is fixedly set relative to the second part 212.

[0065] The connecting portion 230 in this embodiment may be disposed on the first portion 211 and the second portion 212, or it may be disposed on only the first portion 211 or the second portion 212. For example... Figure 6 As shown, the width of the first part 211 is smaller than the width of the second part 212. Of course, the width of the first segment 210 can be varied according to the usage requirements. In this case, the specifications of the mounting groove 110 can be consistent with the specifications of the first segment 210 to ensure the interference fit between the conductor 200 and the mounting groove 110.

[0066] It should be noted that the connection between the first part 211 and the second part 212 is not limited to the connection hole 2111, the connecting piece 240, and the flange 2121. Other connection methods can also be used, as long as the connection requirements between the first part 211 and the second part 212 are met. In addition, besides being formed separately and then connected, the first segment 210, the first part 211, and the second part 212 can also be formed as a single piece, that is, the conductor 200 is formed as a single piece, which can also meet the usage requirements of the conductor 200.

[0067] In one possible implementation, such as Figure 3 As shown, there are three mounting slots 110. The three mounting slots 110 are spaced apart and arranged side by side along a preset direction. The conductor 200 and the connector 120 are correspondingly provided with the mounting slots 110. The housing 100 is provided with at least one weight reduction slot 130 located between two adjacent mounting slots 110.

[0068] The three mounting slots 110 here allow for the installation of three conductors 200 on the housing 100. The three conductors 200 are specifically the three-phase components of the controller. In addition, the weight reduction slots 130 help reduce the weight of the housing 100, thereby facilitating the lightweight design of the controller.

[0069] In this embodiment, the preset direction can be, for example, the width direction of the housing 100. The specific arrangement can be determined according to requirements. Taking a motor controller as an example, one end of each conductor 200 is used to electrically connect to the power module in the motor controller, and the other end is used to electrically connect to the motor, thereby transmitting the three-phase AC power converted by the power module to the motor.

[0070] In this embodiment, the weight-reducing grooves 130 are specifically arranged in multiple manner between two adjacent mounting grooves 110, and the multiple weight-reducing grooves 130 are also spaced apart along the extension direction of the conductor 200. This facilitates further improvement in the weight-reduction effect. It is understood that the number, position, and shape of the weight-reducing grooves 130 can be determined according to requirements.

[0071] In this embodiment of the controller, the conductor 200 can be positioned on the housing 100 by directly inserting it into the mounting slot 110. Then, the conductor 200 is fixed to the mounting slot 110 by thermal riveting with the connector 120. This allows the conductor 200 to be insulated by the housing 100, eliminating the need for a plastic outer shell and simplifying the assembly process.

[0072] Furthermore, by fixing the conductor 200 to the mounting groove 110 via the connector 120, the conductor 200 cannot move relative to the mounting groove 110. Even if the housing 100 vibrates, it is less likely to cause powdering at the connection between the conductor 200 and the connector 120, thus ensuring the reliability and firmness of the conductor 200 connection. Moreover, the connector 120 can also work with the housing 100 to partially enclose the conductor 200 circumferentially, which also helps to improve the insulation effect on the outside of the conductor 200.

[0073] The powertrain of this application embodiment includes a motor and a controller as described above that is electrically connected to the motor.

[0074] Specifically, the controller in the powertrain is the motor controller. The motor and the motor controller work together. The motor controller is used to control the operating status of the motor, and the feedback signal of the motor affects the control commands of the motor controller to the motor.

[0075] The motor controller includes a power module disposed within the housing 100. One end of the conductor 200 in the motor controller is electrically connected to the power module, and the other end is electrically connected to the motor, so as to transmit the AC power output by the power module to the motor.

[0076] Here, the conductor 200 in the motor controller can be installed on the housing 100 through the mounting slot 110 and the connector 120, which simplifies the assembly process of the motor controller and improves the assembly efficiency of the motor controller. The connection of the conductor 200 on the housing 100 is firm and reliable, which helps to ensure the stability of the conductor 200 in use, so that the motor controller and the motor have a good working effect, which in turn helps to improve the stability of the powertrain in use.

[0077] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.

[0078] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
