Description

Technical Field

[0001] This application relates to the field of motor controller technology, and in particular to motor controllers. Background Technology

[0002] Motor controller housings typically have a terminal block with a conductive component fixed to it. One end of the conductive component extends into the motor controller housing and connects to the terminals of the motor controller body, while the other end is located outside the motor controller housing and connects to the motor terminals to achieve current transmission. However, since the connection point between the conductive component and the motor terminals is located outside the housing, it is susceptible to environmental influences during long-term operation. This can lead to oxidation or corrosion at the connection point, potentially causing poor contact or short circuits, thus affecting the reliability of the motor controller. Utility Model Content

[0003] Therefore, it is necessary to provide a motor controller to address the problem of poor contact or short circuits that easily occur at the connection points between conductive components and motor terminals.

The limiting hole is used to limit the position of the low voltage wire harness after it passes through the second hole.

[0015] In one embodiment, the housing includes:

[0016] The shell body includes multiple plates that form a first chamber, and one of the plates has a connecting hole to form a connecting element.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0042] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0043] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0046] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0047] See Figure 1 and Figure 2 A motor controller includes a motor controller body, a housing 10, a wiring assembly 20, and a potting portion 50. The motor controller body includes a motor controller terminal block 01. The housing 10 has two independent chambers, a first chamber 101 and a second chamber 102, with the motor controller body disposed within the first chamber 101. The wiring assembly 20 includes a terminal block 21 and a conductive element 22. The terminal block 21 is disposed on the housing 10, and the conductive element 22 is disposed on the terminal block 21. A first end of the conductive element 22 is disposed within the first chamber 101 and connected to the motor controller terminal block 01, while a second end of the conductive element 22 is disposed within the second chamber 102 and connected to the motor controller terminal block 02. The potting portion 50 is disposed within the second chamber 102 and at least covers the second end of the conductive element 22 and the motor terminal block 02.

[0048] In the aforementioned motor controller, the second end of the conductive component 22 and the motor terminal 02 are encapsulated by the potting portion 50. This configuration improves the stability of the connection between the second end of the conductive component 22 and the motor terminal 02, reducing loosening or poor contact caused by vibration during long-term operation of the motor controller. At the same time, it reduces the erosion or contamination of the connection area between the conductive component 22 and the motor terminal 02 by moisture, dust and other impurities in the environment, reducing the risk of connection failure or short circuit between the conductive component 22 and the motor terminal 02, and improving the reliability of the motor controller operation.

[0049] In some embodiments, the potting portion 50 includes a potting material cured within the second chamber 102. Specifically, the potting portion 50 is formed by filling the second chamber 102 with potting material and then curing it. This arrangement provides space for the potting material within the second chamber 102, improving the ease and stability of forming the potting portion 50.

[0050] In some embodiments, the housing 10 includes a connecting member 103, through which a first chamber 101 and a second chamber 102 are connected. A conductive element 22 passes through the connecting member 103, and at least a portion of the terminal block 21 is disposed within the second chamber 102. A potting portion 50 encapsulates at least a portion of the terminal block 21. This arrangement ensures that the potting portion 50 simultaneously encapsulates at least a portion of the conductive element 22 and at least a portion of the terminal block 21, thus fixing both the terminal block 21 and the conductive element 22 to the potting portion 50. This reduces the relative displacement between the conductive element 22 and the terminal block 21 caused by vibration, improving the stability of the conductive element 22.

[0051] Furthermore, one end of the terminal block 21 is disposed in the first chamber 101, and the other end extends into the second chamber 102 through the connecting member 103. The potting portion 50 seals the gap between the hole wall of the connecting member 103 and the terminal block 21. Moisture may exist in the first chamber 101. After the potting portion 50 seals the gap between the connecting member 103 and the terminal block 21, it can reduce the possibility of moisture from the first chamber 101 entering the second chamber 102, reduce the erosion of the connection between the conductive component 22 and the motor terminal block 02 by moisture, and further improve the reliability of the connection between the conductive component 22 and the motor terminal block 02.

[0052] See Figure 1 and Figure 3 The connecting member 103 is provided with a first hole 1031 and a second hole 1032 that are interconnected along a first direction. The terminal block 21 passes through the first hole 1031, and the outline of the portion of the terminal block 21 opposite to the first hole 1031 is adapted to a portion of the outline of the first hole 1031. The second hole 1032 is used for the low-voltage wiring harness of the power supply to pass through, and a portion of the outline of the second hole 1032 is adapted to the outline of the low-voltage wiring harness. This arrangement minimizes the gap between the terminal block 21 and the low-voltage wiring harness and the hole wall of the connecting member 103 after the terminal block 21 and the low-voltage wiring harness of the motor are installed, reducing the possibility of the potting compound 50 flowing from the connecting member 103 to the first chamber 101 during the potting process. In addition, the second hole 1032 eliminates the need to make additional holes for the low-voltage wiring harness to pass through on the housing 10, simplifying the structure of the housing 10, and allowing the low-voltage wiring harness to be as close as possible to the terminal block 21, which is beneficial for wiring harness layout. Figure 1 and Figure 3 In the diagram, the X direction is the first direction.

[0053] Furthermore, the motor controller also includes a sealing part, which is annularly disposed between the terminal block 21 and the bore wall of the connecting member 103. The sealing part is also provided with a wire through hole for the low-voltage wiring harness to pass through. This arrangement can further improve the sealing performance between the bore wall of the connecting member 103 and the terminal block 21 and the low-voltage wiring harness.

[0054] See Figure 1 In some embodiments, the terminal block 21 has a first sidewall and a second sidewall disposed opposite to each other along the direction from the first hole 1031 to the second hole 1032. The motor controller also includes a first connecting portion 31 and a second connecting portion 32. Both the first connecting portion 31 and the second connecting portion 32 are located within the first chamber 101. One end of the first connecting portion 31 is disposed on the second sidewall, and the other end extends along a first direction away from the terminal block 21 and is fixedly connected to the housing 10. One end of the second connecting portion 32 is disposed on the first sidewall, and the other end extends along the first direction away from the terminal block 21 and is fixedly connected to the housing 10. This arrangement provides two connection positions between the terminal block 21 and the housing 10, improving the stability of the fixation between the terminal block 21 and the housing 10.

[0055] Furthermore, a limiting hole 3101 is formed between the first connecting part 31, the terminal block 21, and the housing 10. The limiting hole 3101 is disposed opposite to the second hole 1032, and the limiting hole 3101 is used to limit the position of the low-voltage harness after passing through the second hole 1032. This arrangement can limit the direction of the low-voltage harness after passing through the second hole 1032, reduce the disorderly extension of the low-voltage harness after passing through the second hole 1032, and facilitate the connection between the low-voltage harness of the motor and the low-voltage harness of the motor controller.

[0056] Specifically, the first connecting portion 31 includes a first segment 311, a second segment 312, and a third segment 313 connected sequentially. The first segment 311 extends along a first direction and is spaced apart from the second hole 1032. The end of the first segment 311 away from the second segment 312 is connected to the second sidewall of the terminal block 21. The second segment 312 extends along a second direction towards the side closest to the second hole 1032, and the second direction is perpendicular to the first direction. The third segment 313 extends along the first direction away from the terminal block 21, and the end of the third segment 313 away from the second segment 312 is fixedly connected to the housing 10. This arrangement makes the first connecting portion 31 a bent structure, enabling it to connect the terminal block 21 to the housing 10 while simultaneously forming a limiting hole 3101 between the terminal block 21 and the housing 10, thus improving the utilization rate of the first connecting portion 31. Figure 1 The Z-direction is the second direction.

[0057] See Figures 1 to 3The housing 10 includes a housing body 11 and a retaining portion 12. The housing body 11 includes multiple plates that form a first chamber 101. One of the plates has a connecting hole 1030 to form a connecting element 103. The retaining portion 12 is detachably connected to the housing body 11 and is arranged in a ring around the outside of the connecting hole 1030. The retaining portion 12 and the housing body 11 together form a second chamber 102. The end of the second chamber 102 away from the housing body 11 forms a glue-filling port 1021. Specifically, the retaining portion 12 is detachably connected to the connecting element 103, and the retaining portion 12 and the connecting element 103 together form the second chamber 102. Furthermore, the connecting hole 1030 includes a first hole 1031 and a second hole 1032 that are interconnected. With this configuration, when installing the terminal block 21, the terminal block 21 can be connected to the housing body 11 first, and then the retaining portion 12 can be installed, improving the convenience of connecting the terminal block 21 to the housing 10.

[0058] Furthermore, an installation groove is provided on the outer wall of the connecting member 103, and the end of the enclosure part 12 away from the glue inlet 1021 is set in the installation groove and positioned and engaged with the installation groove. This arrangement allows the installation groove to position the enclosure part 12 during installation, thereby improving the stability of the connection of the enclosure part 12.

[0059] See Figure 1 and Figure 4 The terminal block 21 is provided with a limiting channel 210. The limiting channel 210 has a first opening 2101 and a second opening 2102 at its two ends. The first opening 2101 is located within the first chamber 101, and the second opening 2102 is located within the second chamber 102. The conductive element 22 passes through the limiting channel 210, and the limiting channel 210 and the conductive element 22 are in a limiting fit. Both ends of the conductive element 22 protrude outwards from the first opening 2101 and the second opening 2102, respectively. The portion of the terminal block 21 corresponding to the limiting channel 210 passes through the connecting member 103. The limiting channel 210 reduces the shaking of the conductive element 22 relative to the terminal block 21, improving the stability of the conductive element 22 during installation. Furthermore, the portion of the terminal block 21 corresponding to the limiting channel 210 passes through the connecting member 103. This arrangement prevents deformation of the conductive element 22 due to contact with the hole wall of the connecting member 103, thus improving the structural stability of the conductive element 22.

[0060] Specifically, along the second direction, the first chamber 101 and the second chamber 102 are located on both sides of the connecting member 103, and the limiting channel 210 extends along the second direction. The limiting channel 210 restricts the swaying of the conductive member 22 in the first direction and the third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other. This arrangement allows the limiting channel 210 to extend in a straight line, improving the ease of forming the limiting channel 210. Figure 1 and Figure 4 The Z-direction is the second direction.

[0061] See Figure 1 , Figure 4 and Figure 5 The connector 21 includes a connector body 211 and a shielding portion 212. Along a third direction, the shielding portion 212 is spaced apart from the connector body 211, forming a limiting channel 210 between them. Along the extending direction of the limiting channel 210, both ends of the connector body 211 protrude outwards from both ends of the shielding portion 212, and both ends of the conductive member 22 are fixedly connected to both ends of the connector body 211. This arrangement ensures that the connection point between the conductive member 22 and the connector body 211 is located outside the limiting channel 210, improving the ease of connection between the conductive member 22 and the connector body 211. Furthermore, this arrangement provides two connection points between the conductive member 22 and the connector body 211, enhancing the stability of the connection between the conductive member 22 and the connector body 211. Figure 5 In the diagram, the Y direction represents the third direction.

[0062] In some embodiments, along the second direction, the end face of the base body 211 located within the first chamber 101 forms a limiting surface. The conductive element 22 includes a main body segment 221 and a first limiting segment 222 connected to each other. The main body segment 221 extends along the second direction and passes through the limiting channel 210. The first limiting segment 222 extends along the third direction and is located within the first chamber 101, abutting against the limiting surface to restrict the movement of the conductive element 22 along the direction from the first chamber 101 to the second chamber 102. This arrangement can further improve the stability of the connection between the conductive element 22 and the terminal block 21 and reduce the possibility of the conductive element 22 shifting along the second direction.

[0063] In some embodiments, there are multiple conductive elements 22, which are spaced apart along a first direction. The motor controller also includes a first insulating barrier 41 and a second insulating barrier 42, both of which are disposed on the base body 211. The first insulating barrier 41, the second insulating barrier 42, and the shielding portion 212 are located on the same side of the base body 211, and along the second direction, the first insulating barrier 41 and the second insulating barrier 42 are respectively located on both sides of the shielding portion 212. A first insulating barrier 41 is disposed between the first ends of two adjacent conductive elements 22, and a second insulating barrier 42 is disposed between the second ends of two adjacent conductive elements 22. The first insulating barrier 41 and the second insulating barrier 42 respectively insulate the ends of adjacent conductive elements 22, reducing or avoiding the risk of short circuits between adjacent conductive elements 22 and improving the safety and reliability of the motor controller.

[0064] See Figure 4The conductive component 22 is provided with a first connecting hole 2201. The terminal block 21 also includes a fixing part 213 and a fastener 214. The fixing part 213 is disposed inside the base body 211 and has a second connecting hole 2130. The second connecting hole 2130 is disposed opposite to the first connecting hole 2201. Along the axial direction of the second connecting hole 2130, the fixing part 213 and the base body 211 are mutually restrictive to limit the movement of the fixing part 213 towards the first connecting hole 2201. The fastener 214 passes through the first connecting hole 2201 and is threadedly connected to the second connecting hole 2130. This arrangement facilitates the fixing of the conductive component 22 and the base body 211 and improves the stability of the connection between the fastener 214 and the fixing part 213.

[0065] See Figure 1 and Figure 4 The main body segment 221 of the conductive element 22 has a first connecting hole 2201 at one end of the second chamber 102. This first connecting hole 2201 extends along a third direction and is located on the side of the shielding portion 212 away from the connecting member 103. A corresponding fixing portion 213 is provided inside the end of the seat body 211 located within the second chamber 102. Additionally, the first limiting segment 222 of the conductive element 22 also has a first connecting hole 2201, extending along a second direction. A corresponding fixing portion 213 is also provided inside the end of the seat body 211 located within the first chamber 101. This arrangement allows both ends of the conductive element 22 to be fixed to the seat body 211 via the matching fixing portion 213 and fastener 214, improving the stability of the connection between the conductive element 22 and the seat body 211.

[0066] Furthermore, the motor controller terminal 01 is fixedly connected to the first limiting section 222 of the conductive element 22 via a fastener 214 located in the first chamber 101. The motor terminal 02 is fixedly connected to the main body section 221 of the conductive element 22 via a fastener 214 located in the second chamber 102. This configuration eliminates the need for additional connection structures to connect the conductive element 22 to the motor controller terminal 01 and the motor terminal 02, thus improving the assembly efficiency of the device.

[0067] In some embodiments, a friction structure is provided on the outer wall of the fixing part 213, and the seat body 211 is formed on the fixing part 213 by injection molding. This arrangement can improve the bonding strength between the fixing part 213 and the seat body 211 and reduce the risk of the fixing part 213 loosening or rotating inside the seat body 211.

[0068] In some embodiments, the fixing part 213 includes a fixing section 2131 and a limiting section 2132 coaxially connected. The outer diameter of the second limiting section 2132 is larger than the outer diameter of the fixing section 2131. A second connecting hole 2130 is disposed on the fixing section 2131 and coaxial with it. This arrangement creates a stepped structure between the second limiting section 2132 and the fixing section 2131. When the seat body 211 is injection molded to cover the fixing part 213, the stepped structure can effectively restrict the axial movement of the fixing part 213. This arrangement simplifies the structure of the fixing part 213 and facilitates its processing.

[0069] Furthermore, a friction structure is provided on the outer wall of the fixing section 2131, and the outer wall of the second limiting section 2132 includes at least one anti-rotation plane. This arrangement can reduce or prevent the fixing part 213 from rotating, thereby improving the stability of the fixing part 213.

[0070] In some embodiments, the fixing part 213 is a knurled nut, and the outer wall of the knurled nut has a knurled structure, which serves as a friction structure. The fastener 214 is a bolt. This configuration results in a simple structure and facilitates assembly.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
