Description

Technical Field

[0001] This application belongs to the field of automotive parts technology, and more specifically, relates to a high-voltage wiring harness mounting structure, a motor controller, and a vehicle. Background Technology

[0002] High-voltage wiring harnesses are key components in motor controllers used for high-voltage power transmission. They mainly connect the high-voltage junction box to the motor controller, and are responsible for transmitting the high-voltage power from the power battery to the motor controller. They also support power distribution for components such as inverters. They are the core connection components of the high-voltage system in new energy vehicles. Their core design includes shielding performance, mechanical protection, and sealing to ensure the safety and stability of high-voltage power transmission.

[0003] Currently, the high-voltage wiring harness connecting the motor controller and the battery pack uses a high-voltage connector. Using this high-voltage connector helps reduce the cost of the motor controller. However, due to structural limitations, a window needs to be opened on the top cover of the motor controller, and a separate wiring cover needs to be added to fix the high-voltage connector and ensure a reliable connection between the high-voltage connector and the filter module. This not only increases the cost of the motor controller to some extent, but also increases the installation steps. In addition, a sealing structure needs to be added between the wiring cover and the top cover, which also increases the risk of seal failure of the motor controller. Utility Model Content

[0004] The purpose of this application is to provide an installation structure for a high-voltage wiring harness, a motor controller, and a vehicle, in order to solve the problems of complex installation structures for high-voltage wiring harnesses and the resulting sealing failures.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A high-voltage wiring harness installation structure is provided, comprising: a controller housing, a top cover, an elastic clamping assembly, and a high-voltage connector. A filter module is installed inside the controller housing; the top cover covers the controller housing; the elastic clamping assembly is pre-installed on the inner surface of the top cover and corresponds to the input terminal of the filter module; the terminals of the high-voltage connector pass through the controller housing and are inserted between the elastic clamping assembly and the input terminal of the filter module. The high-voltage wiring harness is electrically connected to the filter module by the elastic clamping assembly and the input terminal of the filter module being elastically clamped together.

[0006] The beneficial effects of the high-voltage wiring harness installation structure provided in this application are as follows: Compared with the prior art, the installation structure of the high-voltage wiring harness in this application does not require opening a window on the top cover to add a wiring cover plate. Instead, the elastic clamping component is pre-installed on the inner surface of the top cover. After the top cover is fixed to the controller housing, the elastic clamping component forms elastic contact with the input end of the filter module inside the controller housing. Then, the wiring terminal of the high-voltage controller is inserted through the controller housing between the elastic clamping component and the input end of the filter module. When the wiring terminal is inserted, it forms a pressure on the elastic clamping component, causing the elastic clamping component to elastically compress, thereby inserting the wiring terminal. The reaction force of the elastic compression of the elastic clamping component is applied to the wiring terminal, causing the wiring terminal to elastically press against the input end of the filter module, thereby achieving a reliable connection between the high-voltage wiring harness and the filter module.

[0007] This installation structure allows the wiring terminals to be connected to the input terminal of the filter module without any special operation. During installation, simply fix the top cover to the controller housing, insert the wiring terminals of the high-voltage connector into the controller housing, and they will be pressed by the elastic clamping component, thus electrically connecting to the filter module. Installation is simple and convenient.

[0008] This mounting structure eliminates the need for bolt holes on the high-voltage connector terminals, increasing the current carrying capacity of the terminals. This allows for a reduction in terminal size based on actual needs, lowering manufacturing costs. Furthermore, it eliminates the need for bolts to secure the high-voltage connector to the filter module's input, reducing assembly steps and making installation simple and convenient.

[0009] This installation structure also eliminates the need for windows on the top cover, thus avoiding the risk of sealing failure caused by installing wiring covers at the windows.

[0010] Since there is no need to open a window on the top cover or install a wiring cover, the high-voltage wiring harness can be installed, reducing manufacturing costs. At the same time, it also reduces the height of the motor controller, which is beneficial for the placement of the motor controller in the vehicle. It also eliminates the cost and installation process of setting a sealing structure for the window, thus reducing the manufacturing cost of the motor controller to a certain extent.

[0011] In conjunction with the first aspect, in one possible implementation, the elastic clamping assembly includes a pressure block and an elastic element disposed between the pressure block and the upper cover; The inner surface of the upper cover is provided with a guide post and an anti-detachment structure provided at the end of the guide post. The pressure block is slidably fitted on the guide post and limited by the anti-detachment structure. The elastic element is elastically pre-pressed between the pressure block and the upper cover.

[0012] In the above technical solution, the pressure block, as a component that directly contacts and presses the terminal block, can also slide along the guide post through the connection. Under the action of the pre-tightened elastic element, the pressure block is connected to the guide post, maintaining an elastic pressing state and continuously pressing the terminal block, so that the terminal block of the high-voltage connector is always in close contact with the input end of the filter module, ensuring the reliability of the electrical connection.

[0013] In conjunction with the first aspect, in one possible implementation, a limiting post is further provided on the inner surface of the upper cover, the elastic element is fitted on the limiting post, and the pressure block is slidably connected to the limiting post; four guide posts are corresponding to the four corners of the pressure block, and the limiting post is located in the middle of the four guide posts.

[0014] In the above technical solution, the elastic element is constrained by limiting posts to ensure that the elastic element expands and contracts in the compression direction without deviation. Simultaneously, guide posts are installed at the four corners of the pressure block to ensure balanced force distribution at each position when the pressure block is pressed downwards, thus ensuring the reliability of the electrical connection.

[0015] In conjunction with the first aspect, in one possible implementation, a sleeve concentric with the limiting post is further provided on the inner surface of the upper cover, and the elastic element is located inside the sleeve; a reserved gap for the sliding of the pressure block is reserved between the sleeve and the pressure block.

[0016] In the above technical solution, the sleeve and the anti-loosening nut together restrict the up and down sliding stroke of the pressure block, which can prevent the pressure block from detaching from the guide post and prevent the pressure block from moving excessively upward along the guide post.

[0017] When the clamping block tightens the terminal block, it is necessary to ensure that the anti-detachment structure does not come into contact with or interfere with the terminal block or other electrical components inside the controller housing, so as to avoid the anti-detachment structure causing scratch damage to the terminal block or other electrical components.

[0018] In conjunction with the first aspect, in one possible implementation, the pressure block is provided with a pressing protrusion extending away from the upper cover, the pressing protrusion pressing against the terminal of the high-voltage connector.

[0019] When the clamping block tightens the terminal block, it is necessary to ensure that the anti-detachment structure does not come into contact with or interfere with the terminal block or other electrical components inside the controller housing, so as to avoid the anti-detachment structure causing scratch damage to the terminal block or other electrical components.

[0020] In conjunction with the first aspect, in one possible implementation, the anti-disengagement structure includes an anti-disengagement nut screwed to the end of the guide post, wherein the height of the clamping protrusion is higher than that of the anti-disengagement nut, so that when the pressure block clamps the terminals of the high-voltage connector, the anti-disengagement nut avoids electrical components within the controller housing.

[0021] In the above technical solution, in order to prevent the anti-loosening nut from rubbing against the surrounding electrical components when the pressure block is tightening the terminal block, the height of the pressure protrusion needs to be designed to ensure that the anti-loosening nut will not interfere with the surrounding electrical components when the pressure block is tightened.

[0022] In conjunction with the first aspect, in one possible implementation, the pressure block has two corresponding pressing protrusions, which respectively press the positive terminal and the negative terminal of the high-voltage connector.

[0023] In the above technical solution, two clamping protrusions are used to clamp the two positive and negative terminals respectively, ensuring the reliability of the electrical connection between the high-voltage harness and the filter module.

[0024] In conjunction with the first aspect, in one possible implementation, the pressing surface of the pressing protrusion is a plane.

[0025] In the above technical solution, since the terminals of the high-voltage connector have a large surface area, they can make full contact with the input end of the filter module, ensuring the reliability of the electrical connection. At the same time, the large surface area contact can also avoid the risk of point contact failure and poor contact.

[0026] Secondly, embodiments of this application also provide a motor controller, including the aforementioned high-voltage wiring harness mounting structure.

[0027] Thirdly, embodiments of this application also provide a vehicle including the aforementioned high-voltage wiring harness mounting structure.

[0028] The motor controller and vehicle provided in this application embodiment use this installation structure for electrical connection between the high-voltage wiring harness and the filter module. This solves the problem of complex installation of the high-voltage wiring harness and avoids the impact of sealing failure on the internal electrical components of the controller. This improves the efficiency and service life of the motor controller assembly and ensures the stability of vehicle operation. Attached Figure Description

[0037] Currently, when electrically connecting high-voltage wiring harnesses to electrical components inside the controller housing, a window needs to be created on the top cover, which is then fixed to the controller housing. The terminals of the high-voltage connector are inserted into the controller housing, and a wiring cover is then fixed at the window to connect the terminals to the input of the filter module. This connection method suffers from several problems: the window on the top cover can lead to poor sealing and seal failure; the addition of a sealing structure and wiring cover also increases manufacturing costs; and the multiple installation steps require more time. Therefore, these issues hinder cost reduction for the motor controller. To address these problems, this application proposes a technical solution that eliminates the need for a window on the top cover.

[0038] Please refer to the following: Figures 1 to 8 The installation structure of the high-voltage wiring harness provided in this application is described below. The installation structure includes a controller housing 2, a top cover 1, an elastic clamping assembly 6, and a high-voltage connector 3. A filter module 5 is installed inside the controller housing 2. The top cover 1 covers the controller housing 2. The elastic clamping assembly 6 is pre-installed on the inner surface of the top cover 1 and corresponds to the input terminal of the filter module 5. The terminals of the high-voltage connector 3 pass through the controller housing 2 and are inserted between the elastic clamping assembly 6 and the input terminal of the filter module 5. The high-voltage wiring harness 4 and the filter module 5 are electrically connected by the elastic clamping assembly 6 and the input terminal of the filter module 5.

[0039] Compared with the prior art, the installation structure of the high-voltage wiring harness 4 provided in this application does not require opening a window on the upper cover 1 to add a wiring cover plate. Instead, the elastic clamping component 6 is pre-installed on the inner surface of the upper cover 1. After the upper cover 1 is fixed to the controller housing 2, the elastic clamping component 6 forms elastic contact with the input end of the filter module 5 inside the controller housing 2. Then, the wiring terminal of the high-voltage controller is inserted through the controller housing 2 between the elastic clamping component 6 and the input end of the filter module 5. When the wiring terminal is inserted, it forms a pressure on the elastic clamping component 6, causing the elastic clamping component 6 to elastically compress, thereby inserting the wiring terminal. The reaction force of the elastic compression of the elastic clamping component 6 is applied to the wiring terminal, causing the wiring terminal to elastically press against the input end of the filter module 5, thereby achieving a reliable connection between the high-voltage wiring harness 4 and the filter module 5.

[0040] This installation structure allows the wiring terminals to be connected to the input terminal of the filter module 5 without special operation. During installation, simply fix the top cover 1 to the controller housing 2 and insert the wiring terminals of the high-voltage connector 3 into the controller housing 2 to achieve a reliable electrical connection between the high-voltage harness 4 and the filter module 5. This reduces the installation time of fixing the wiring cover with bolts, reduces assembly steps, and makes installation simple and convenient.

[0041] This mounting structure eliminates the need for bolt holes on the high-voltage connector terminals, increasing the current carrying capacity of the terminals. This allows for a reduction in terminal size based on actual needs, lowering manufacturing costs. Furthermore, it eliminates the need for bolts to secure the high-voltage connector to the filter module's input, reducing assembly steps and making installation simple and convenient.

[0042] This installation structure also eliminates the need for opening windows on the top cover 1, thus avoiding the risk of sealing failure caused by installing wiring cover plates at the windows.

[0043] Since there is no need to open a window on the top cover 1 or set up a wiring cover, the high-voltage wiring harness can be installed, which reduces the manufacturing cost. At the same time, it also reduces the height of the motor controller, which is beneficial for the layout of the motor controller in the vehicle. It also eliminates the cost and installation process of setting up a sealing structure for the window, which reduces the manufacturing cost of the motor controller to a certain extent.

[0044] In this application, the pressure block is made of insulating material, which avoids the risk of electrical leakage and ensures the safety of the electrical connection. The insulating material can be any of bakelite, polyethylene, polytetrafluoroethylene, etc.

[0045] The connection between the top cover and the controller housing is a conventional technique, such as bolting or snap-fitting. To ensure the airtightness of the motor controller, a sealing ring is installed between the top cover and the controller housing.

[0046] The filter module is fixed inside the controller housing with bolts. The output end of the filter module is electrically connected to the capacitor by bolts or laser welding, and the input end is electrically connected to the high-voltage wiring harness. The terminals of the high-voltage connector are inserted into the controller housing and then fixed to the controller housing by bolts.

[0047] In some embodiments, see Figures 5 to 8 The elastic pressing assembly 6 includes a pressing block 61 and an elastic element 66 disposed between the pressing block 61 and the upper cover 1; a guide post 62 is provided on the inner surface of the upper cover 1, the pressing block 61 is slidably fitted on the guide post 62, and the elastic element 66 is elastically pre-pressed between the pressing block 61 and the upper cover 1.

[0048] In the above technical solution, the pressure block 61, as a component that directly contacts and presses the terminal block, can slide along the guide post 62 after being connected to it. Under the action of the pre-tightened elastic element 66, the pressure block 61 is connected to the guide post 62, maintaining an elastic pressing state and continuously pressing the terminal block, so that the terminal block of the high voltage connector 3 is always in close contact with the input end of the filter module 5, ensuring the reliability of the electrical connection.

[0049] As an optional implementation, the connection between the pressure block 61 and the upper cover 1 can also be achieved by directly connecting multiple elastic elements 66. That is, the elastic elements 66 are directly connected between the pressure block 61 and the upper cover 1. This allows multiple elastic elements 66 to be evenly connected on the pressure block 61, ensuring the uniformity of force on the pressing surface of the pressure block 61 and the reliability of the electrical connection. For example, elastic elements 66 can be provided at the four corners of the pressure block 61, and an elastic element 66 can also be provided at the geometric center of the pressure block 61.

[0050] However, since the elastic element 66 has good deformability, it is easy to deviate in the direction of elastic compression. Therefore, in the following embodiment, a limiting post 65 is used to constrain the compression direction of the elastic element 66.

[0051] In some embodiments, see Figures 5 to 8 On the inner surface of the upper cover 1, there is also a limiting post 65. The elastic element 66 is fitted on the limiting post 65. The pressure block 61 is slidably connected to the limiting post 65. There are four guide posts 62 at the four corners of the pressure block 61. The limiting post 65 is located in the middle of the four guide posts 62.

[0052] In the above technical solution, the elastic element 66 is constrained by the limiting post 65 to ensure that the elastic element 66 expands and contracts in the compression direction without deviation. At the same time, guide posts 62 are respectively set at the four corners of the pressure block 61 to ensure the balance of force at each position when the pressure block 61 is pressed down, and to ensure the reliability of the electrical connection.

[0053] As an alternative implementation, the elastic element 66 can also be directly fitted onto the guide post 62 without the need for an additional limiting post 65.

[0054] In the above technical solution, the limiting post 65 and the guide post 62 can have the same structure; the guide post 62 can be an integral structure that is injection molded onto the upper cover 1, or it can be glued to the upper cover 1, or it can have a threaded hole formed on the upper cover 1. The upper end of the guide post 62 is threadedly connected to the upper cover 1. In this case, the guide post 62 can be supported by a suitable bolt, and the nut of the bolt also serves as the anti-detachment structure 63 of the limiting pressure block 61.

[0055] Optionally, the anti-detachment structure 63 of the pressure block 61 on the guide post 62 can also be an anti-detachment nut or a shaft retaining ring threaded to the end of the guide post 62. Both can prevent the pressure block 61 from falling off the guide post 62, and neither will affect the upward sliding of the pressure block 61 along the guide post 62 under the thrust when the terminal is inserted.

[0056] Optionally, the anti-loosening structure 63 can also be a bolt threaded onto the guide post 62. In this case, the guide post 62 is provided with an internal threaded hole for connection with the bolt. Figure 8 The indicator shows that an internal threaded hole is provided on the limit post 65.

[0057] In this application, the elastic element 66 is preferably a compression spring.

[0058] In some embodiments, see Figure 6 and Figure 8 On the inner surface of the upper cover 1, there is also a sleeve 67 concentric with the limiting post 65, and the elastic element 66 is located inside the sleeve 67; a reserved gap H is reserved between the sleeve 67 and the pressure block 61 for sliding.

[0059] The sleeve 67 has a limiting function for the elastic element 66, which can prevent the elastic element 66 from deflecting when compressed. Therefore, a gap needs to be reserved between the sleeve 67 and the pressure block 61. This reserved gap is the stroke of the pressure block 61 sliding along the limiting post 65 and the guide post 62; therefore, the sleeve 67 has a limiting function for the pressure block 61.

[0060] Combined with the anti-detachment structure 63 at the end of the guide post 62, the sleeve 67 and the anti-detachment nut together restrict the up-and-down sliding stroke of the pressure block 61, which can prevent the pressure block 61 from detaching from the guide post 62 and prevent the pressure block 61 from moving excessively upward along the guide post 62.

[0061] When the pressure block 61 presses the terminal block, it is necessary to ensure that the anti-detachment structure 63 does not come into contact with or interfere with the terminal block or other electrical components inside the controller housing 2, so as to avoid the anti-detachment structure 63 causing scratch damage to the terminal block or other electrical components.

[0062] Therefore, in some embodiments, see Figure 6 and Figure 8 The pressure block 61 is provided with a pressing protrusion 64 extending away from the upper cover 1, which presses against the wiring terminals of the high-voltage connector 3. The pressing protrusion 64 prevents the anti-detachment structure 63 on the guide post 62 from interfering with the wiring terminals.

[0063] As an alternative implementation, a countersunk hole can be provided on the pressure block 61, and the nut of the bolt, which serves as the anti-loosening structure 63, is hidden in the countersunk hole. The depth of the countersunk hole needs to ensure that even if the pressure block 61 slides upward, the nut will not be exposed outside the countersunk hole, and there will be no interference with the wiring terminals.

[0064] In some embodiments, see Figure 6 The anti-disengagement structure 63 includes an anti-disengagement nut screwed to the end of the guide post 62. The height of the pressing protrusion 64 is higher than that of the anti-disengagement nut so that the anti-disengagement nut avoids electrical components inside the controller housing 2 when the pressure block 61 presses the wiring terminals of the high-voltage connector 3.

[0065] The anti-loosening structure 63 has been described in various ways. In order to prevent the anti-loosening nut from rubbing against the surrounding electrical components when the pressure block 61 is pressing the terminal, the height of the pressing protrusion 64 needs to be designed to ensure that the anti-loosening nut will not interfere with the surrounding electrical components when the pressure block 61 is pressed.

[0066] In some embodiments, see Figure 6 and Figure 8 The pressure block 61 has two corresponding pressing protrusions 64, which press the positive and negative terminals of the high-voltage connector 3 respectively. By pressing the two positive and negative terminals respectively with the two pressing protrusions 64, the reliability of the electrical connection between the high-voltage wiring harness 4 and the filter module 5 is ensured.

[0067] In some embodiments, see Figure 6 and Figure 8 The pressing surface of the pressing protrusion 64 is flat. Because the terminals of the high-voltage connector 3 have a large surface area, they can make full contact with the input terminal of the filter module 5, ensuring the reliability of the electrical connection. At the same time, the large surface area contact can also avoid the risk of point contact failure and poor contact.

[0068] Therefore, the pressing surface of the corresponding pressing protrusion 64 also contacts the terminal block surface, ensuring the balance of the pressing force applied to the terminal block, thereby ensuring the reliability of the electrical connection.

[0069] Alternatively, the pressing surface of the pressing protrusion 64 can also be an arc-shaped surface.

[0070] Based on the same inventive concept, embodiments of this application also provide a motor controller, including the aforementioned high-voltage wiring harness mounting structure, see [link to relevant documentation]. Figures 1 to 4 .

[0071] Based on the same inventive concept, this application also provides a vehicle including the aforementioned high-voltage wiring harness mounting structure.

[0072] The motor controller and vehicle provided in this application embodiment use this installation structure for electrical connection between the high-voltage wiring harness 4 and the filter module 5. This solves the problem of complex installation of the high-voltage wiring harness 4 and avoids the impact of sealing failure on the internal electrical components of the controller. This improves the efficiency and service life of the motor controller assembly and ensures the stability of vehicle operation.
