Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor controller technology, specifically to a guide column mounting structure and a motor controller. Background Technology
[0002] The motor controller is the core component for controlling the operation of a motor. By adjusting parameters such as voltage, current, and frequency, it enables precise control of the motor's speed, torque, and direction. It is widely used in electric vehicles, industrial automation, robotics, and other fields.
[0003] Motor controllers typically include a driver board, on which power devices such as MOSFETs and IGBTs are arranged to perform the inverter function of converting DC power into three-phase AC power. In addition to power devices, the driver board also needs to accommodate three-phase current guides and other electronic components. The three-phase current guides occupy a large amount of space on the driver board, and the two are highly interconnected, making decoupling difficult and affecting the layout of electronic components.
[0004] Specifically, such as Figure 1-3 As shown, the existing flow guide column 1' has a flow guide strip 2' integrated at its bottom. After determining the position of the flow guide column 1', the flow guide strip 2' is fastened to the drive plate 3' with screws. Because the flow guide strip 2' occupies a large space, the layout space for electronic components is reduced; moreover, because the position of the flow guide strip 2' is fixed, electronic components need to be arranged adaptively, affecting layout flexibility. Furthermore, as... Figure 1 , 4 As shown, the guide column 1' is provided with mounting holes 12' for mounting the three-phase wire lugs 4' of the motor. Since the mounting contact surface 11' of the mounting hole 12' is a plane, when the wire lugs 4' of the motor lead are installed and overlapped on the guide column 1', the wire lugs 4' may rotate with the movement of the three-phase wires of the motor, which may lead to problems such as loosening and poor contact, reducing the reliability of equipment operation. Utility Model Content
[0005] This invention addresses the technical problem in existing technologies where the installation structure of the guide column is highly correlated with the drive board, thus affecting the arrangement space and flexible layout of electronic components on the drive board. It proposes a guide column installation structure that increases the arrangement space and layout flexibility of electronic components on the drive board, and the installation structure is stable, low-cost, and highly feasible.
[0006] The technical solution of this utility model:
[0007] A flow guide column mounting structure, comprising:
[0008] A flow guide column, one end of which is used for electrical connection with the outside, and the other end of which is connected to a flow guide.
[0009] The flow guide includes a connecting section, a bending section, and an overlapping section. The connecting section is used to install and connect to the drive plate. The bending section raises the overlapping section away from the drive plate. The overlapping section is used to overlap with the flow guide column.
[0010] Furthermore, one end of the guide post is formed with an overlapping plane and a mounting hole adapted to the wire nose, and an anti-rotation structure is provided between the overlapping plane and the wire nose to prevent the wire nose from rotating.
[0011] Furthermore, the anti-rotation structure is an anti-rotation protrusion formed on the left and / or right side of the overlapping plane.
[0012] Furthermore, the guide tube includes two connecting sections and a bending section. Both connecting sections are installed and connected to the drive plate. The bottom ends of the two bending sections are connected to the connecting sections one by one, and the top ends of the two bending sections are connected to the overlapping section.
[0013] Furthermore, the overlapping section includes an overlapping area for direct overlap with the guide column and a transition area for extending the overlapping area to the target position.
[0014] Furthermore, the flow guide is formed by stamping, and the flow guide is made of aluminum.
[0015] In another aspect, this utility model provides a motor controller, including the flow guide column mounting structure as described in any of the above.
[0016] Furthermore, the motor controller includes three guide columns, with the two outer guide columns arranged symmetrically.
[0017] After adopting the above technical solution, the guide column installation structure and motor controller provided by this utility model have the following beneficial effects compared with the prior art: This utility model sets a guide column at the bottom of the guide column. The guide column includes a connecting section, a bending section and an overlapping section. Since the overlapping section is raised by the bending section, only the connecting section is connected to the drive board, thus reducing the space occupied on the drive board and increasing the layout space of the electronic components on the drive board. Moreover, in this embodiment, the electronic components on the drive board can be laid out first, only needing to leave space to install the connecting section. Then, it can be raised by the bending section and extended by the overlapping section to overlap with the guide column at the target position. This provides more options for the arrangement of electronic components on the drive board, improving the flexibility and convenience of the arrangement of electronic components on the drive board.

[0035] like Figure 5-8As shown, this embodiment provides a guide column mounting structure suitable for a motor controller. The mounting structure includes a guide column 1 and a guide busbar 2. One end of the guide column 1 is used for electrical connection to an external device, such as a motor lead wire, and the other end overlaps with the guide busbar 2. Further, the guide busbar 2 includes a connecting section 21, a bending section 22, and an overlapping section 23. The connecting section 21 is used for mounting to a drive plate 3, and connecting holes can be provided on the connecting section 21 for installation with screws or other fasteners. The bottom end of the bending section 22 is connected to the connecting section 21, and the top end of the bending section 22 is connected to the overlapping section 23. The bending section 22 bends upwards away from the drive plate 3, thereby raising the overlapping section 23. The overlapping section 23 is used to overlap with the guide column 1, for example, through welding or fastener connection.
[0036] Thus, the flow guide column installation structure provided in this embodiment, compared with the prior art, has a flow guide row 2 set at the bottom of the flow guide column 1. The flow guide row 2 includes a connecting section 21, a bending section 22, and an overlapping section 23. Since the overlapping section 23 is raised by the bending section 22, only the connecting section 21 connects with the drive board 3, thus reducing its space occupation on the drive board 3 and increasing the layout space of the electronic components on the drive board 3. Moreover, in this embodiment, the electronic components on the drive board 3 can be laid out first, only requiring space to install the connecting section 21. Then, it can be raised by the bending section 22 and extended by the overlapping section 23 to overlap with the flow guide column 1 at the target position. This provides more options for the arrangement of electronic components on the drive board 3, improving the flexibility and convenience of the electronic component arrangement on the drive board 3.
[0037] like Figure 5 , 9 As shown in Figure -10, in this embodiment, an overlapping plane 11 and a mounting hole 12 for the motor lead wire lug 4 are formed at one end of the guide post 1. The motor lead wire lug 4 contacts the overlapping plane 11, and mounting holes are also provided on the motor lead wire lug 4 for installation with fasteners. The overlapping plane 11 is preferably a vertical plane, so that the lug 4 can be installed vertically, reducing the lateral space occupied.
[0038] Furthermore, this embodiment also provides an anti-rotation structure between the overlapping plane 11 and the lug 4 to prevent the lug 4 from rotating, thus preventing the lug 4 from rotating around the mounting hole 12 after installation and improving reliability. Preferably, the anti-rotation structure is an anti-rotation protrusion 13 formed on the left and / or right side of the overlapping plane 11. This anti-rotation protrusion 13 can limit the installation of the lug 4 and prevent it from rotating. The anti-rotation structure can be obtained by machining a mounting groove, with the bottom surface of the mounting groove forming the overlapping plane 11 and the two sides of the mounting groove forming the anti-rotation protrusion 13. This is easy to process and has low cost. Of course, other anti-rotation structures can also be provided in other embodiments, such as an anti-rotation groove on the left and / or right edge of the overlapping plane 11, and an anti-rotation protrusion on the lug 4 that can be inserted into the anti-rotation groove to achieve the anti-rotation function.
[0039] like Figure 5-8 As shown, the overlapping section 23 in this embodiment includes an overlapping area 231 and a transition area 232. The shape of the overlapping area 231 is adapted to the flow guide column 1 for direct overlap with the flow guide column 1. The transition area 232 connects partly to the bending section 22 and partly to the overlapping area 231, thereby extending the overlapping area 231 to the target position. After the electronic components on the drive board 3 are arranged, the installation position of the connecting section 21 may be far from the corresponding flow guide column 1, which can be extended through the transition area 232. The transition area 232 can also be provided with clearance holes or weight reduction holes as needed.
[0040] Furthermore, to enhance the fixation effect on the guide column 1, the guide column 2 in this embodiment includes two connecting sections 21 and a bent section 22. Both connecting sections 21 are mounted on the drive plate 3, and their mounting positions on the drive plate 3 can be set as needed. The bottom ends of the two bent sections 22 are connected to the corresponding connecting sections 21, and the top ends of the two bent sections 22 are connected to the overlapping section 23. This support and connection by the two connecting sections 21 and the bent section 22 improves the fixation effect on the guide column 1, especially when the distance between the connecting section 21 and the corresponding guide column 1 is relatively large. The bent section 22 is preferably bent vertically, thereby reserving more space for the placement of electronic components.
[0041] Preferably, the flow guide 2 in this embodiment is formed by stamping, and the flow guide 2 is an aluminum busbar.
[0042] This embodiment also provides a motor controller, including the flow guide column mounting structure described above. The motor controller includes three flow guide columns 1, forming a three-phase AC flow guide column configuration. The position of each flow guide column 1 can be set as needed, and the flow guide array 2 is adaptively arranged according to the position of each flow guide column 1 and the reserved position on the drive board 3. Preferably, in this embodiment, the two flow guide columns 1 located on the leftmost and rightmost sides are arranged axially symmetrically, so that the flow guide array 2 corresponding to these two flow guide columns 1 has the same structure, which can reduce the types of parts and lower costs.
[0043] As can be seen from the above, the guide column mounting structure and motor controller provided in this embodiment increase the arrangement space and layout flexibility of electronic components on the drive board. Moreover, the mounting structure is stable, low in cost, and highly feasible. In addition, it also improves the reliability of the connection between the guide column and the external wire nose.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
