Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a modular integrated drive and control motor structure. Background Technology

[0002] In modern industrial automation, robotics, CNC machine tools, and other fields, servo motors are core actuators, and their performance and reliability are crucial. Traditional servo systems typically employ a separate "driver + motor" structure, where the controller and motor are two independent components electrically connected via external cables. This separate structure has several drawbacks: First, the large number of external cables and connectors increases system size and wiring complexity, introduces potential connection failure risks, and reduces system reliability. Second, the separate structure hinders miniaturization and integration, occupying significant installation space. Third, if the heat generated by power devices (such as MOSFETs) in the controller cannot be dissipated in time, it will directly affect the lifespan and performance stability of the driver. Finally, the system's grounding design is often dispersed and complex; improper handling can easily introduce electromagnetic interference, affecting control accuracy and even posing safety hazards.

[0003] Therefore, how to provide a modular integrated drive and control motor structure to at least partially solve the above-mentioned drawbacks is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0039] The purpose of this invention is to provide a modular integrated drive and control motor structure. By designing the motor and controller into modules and connecting them, the overall assembly and production becomes more efficient and the structure becomes more reliable. At the same time, the heat dissipation effect of the controller is also improved.

[0040] To achieve the above objectives, the present invention provides the following technical solution:

[0041] Please see Figures 1 to 10 This embodiment provides a modular integrated drive and control motor structure, including: a motor module 100 and a controller module 200; the motor module 100 includes a motor body 110, and a busbar connector 120 is provided on the outer side wall of the motor body 110; the controller module 200 is detachably installed on the motor module 100, and the controller module 200 includes a housing, and a control board 220, a drive board 230 and a module heat sink 240 housed in the housing, the module heat sink 240 abuts between the heating element of the drive board 230 and the inner wall of the housing, and a male connector pin 250 is provided on the outer side of the controller module 200 for plugging and cooperating with the busbar connector 120, the male connector pin 250 is connected to the drive board 230, and the drive board 230 is electrically connected to the control board 220.

[0042] Specifically, such as Figures 1 to 5 As shown, the motor module 100 and the controller module 200 can be detachably connected by screws, and they are independent of each other. Only after they are connected together will they be connected to each other for electrical and signal communication through the mating female busbar connector 120 and male busbar pin 250.

[0043] In this embodiment, the motor module 100 includes a motor body 110 and a busbar connector 120 disposed on one side of its rear end. The motor body 110 is a motor structure in the prior art, which will not be described in detail here. Meanwhile, the controller module 200 can be fixedly installed on the side of the motor body 110 where the busbar connector 120 is disposed by screws. Correspondingly, the controller module 200 is provided with a male header pin 250 at the position corresponding to the busbar connector 120. Specifically, in this embodiment, the male header pin 250 is preferably a pin header, which can be inserted into the busbar connector 120 and communicate with it.

[0044] The controller module 200 has a control board 220 and a drive board 230 installed inside its housing. The control board 220 is responsible for receiving communication signals and power input from the host computer and outputting the communication signals and power voltage to the drive board 230 respectively. The drive board 230 is connected to the motor body 110 through the male connector 250 to realize the drive control of the motor.

[0045] Understandably, during operation, the heat-generating elements on the drive board 230 generate a significant amount of heat, affecting its working efficiency. Therefore, this application also installs a modular heat sink 240 on the upper side of the heat-generating elements on the drive board 230. The modular heat sink 240 conducts the heat generated during operation to the housing, thereby cooling the drive board 230. In this way, by designing and connecting the motor and controller components in a modular fashion, the overall assembly and production become more efficient and the structure more reliable. At the same time, the modular heat sink 240 improves the heat dissipation effect of the heat-generating elements on the drive board 230, enhancing the reliability of the product.

[0046] In one possible implementation, the housing includes: a box 211 with an opening and a cover plate 212 installed at the opening of the box 211. The bottom of the box 211 is installed to the motor body 110. The drive board 230 and the control board 220 of the box 211 are both installed inside the box 211, and the drive board 230 is located at the bottom inside the box 211. One end of the module heat sink 240 abuts against the heating element of the drive board 230, and the other end abuts against the cover plate 212.

[0047] Specifically, such as Figure 2 and Figure 3As shown, the housing in this embodiment comprises two parts. One part is a box 211, preferably square in shape, with an opening at the top and a cavity inside for installing other components of the controller module 200. The other part is a cover plate 212 that covers the opening of the box 211. The cover plate 212 can be detachably installed on the top of the box 211 with screws, thus forming a closed shell. During installation, the bottom outer side of the box 211 is attached to the side wall of the motor body 110 and the two are fixed together with screws. The control board 220 and the drive board 230 are installed parallel to each other in the space inside the box 211. In other words, the two are installed inside the housing 211 in an up-down manner. Specifically, the drive board 230 is located at the bottom of the space inside the housing 211, that is, on the lower side, while the control board 220 is located on the upper side of the drive board 230, that is, near the opening. It should be noted that the area of ​​the control board 220 is smaller than that of the drive board 230. The control board 220 is not installed above the position corresponding to the heating element on the drive board 230. A modular heat sink 240 is installed above the heating element. The top of the modular heat sink 240 can just abut against the cover plate 212. In this way, the heat generated by the heating element can be transferred to the cover plate 212 through the modular heat sink 240, thereby improving the heat dissipation effect.

[0048] In one possible implementation, the box body 211 is made of plastic and is integrally molded by injection molding, while the cover plate 212 is made of metal.

[0049] Understandably, in order to improve the heat dissipation of the heat-generating components of the driver board 230, its cover plate 212 is made of a metal material with fast heat conduction, which can be adjusted according to the actual situation. As for the housing 211, in order to prevent it from shielding the signal of the controller or driver board 230 and to prevent leakage, its material is made of insulating plastic. This setting also facilitates the processing and manufacturing of the housing 211 and can reduce production and manufacturing costs.

[0050] It should be noted that in this embodiment, during the injection molding process, the box 211 has multiple internally threaded insert nuts embedded inside. The internally threaded insert nuts are a structure in the prior art, and their function is to provide threads for screwing. The connection between the cover plate 212 and the box 211, and the connection between the drive plate 230 and the bottom of the box 211 are all achieved by the cooperation of screws and internally threaded insert nuts.

[0051] In a possible implementation, the motor module 100 further comprises a guide boss 130, the guide boss 130 is disposed around the busbar insert 120, a guide groove 2111 is disposed at the bottom of the box body 211, the male busbar pins 250 penetrate through the bottom of the guide groove 2111, and the guide groove 2111 is configured to cooperate with the guide boss 130 to guide the aligned installation of the controller module 200 and the motor module 100, and enable the male busbar pins 250 and the busbar insert 120 to be plugged and conducted.

[0052] It can be understood that, in order to ensure that the motor module 100 and the controller module 200 can be aligned and installed easily, and prevent the male busbar pins 250 and the busbar insert 120 from bending during plugging, in this embodiment, a circle of guide boss 130 with a protruding structure is disposed around the busbar insert 120, correspondingly, a circle of concave guide groove 2111 is disposed around the male busbar pins 250, please refer to Figure 4 and Figure 5 In this way, during the assembly process of the motor module 100 and the controller module 200, automatic alignment can be achieved through the cooperation between the guide groove 2111 and the guide boss 130.

[0053] In a possible implementation, the module heat sink 240 has a square structure, two through air ducts 241 are disposed inside the module heat sink 240, and the material of the module heat sink 240 is metal.

[0054] Specifically as shown in Figure 9 , the module heat sink 240 is entirely made of a metal material with high thermal conductivity, and in order to increase the heat dissipation efficiency, two through air ducts 241 are symmetrically disposed in the middle part in this embodiment, that is, the overall cross-section has a Japanese-shaped structure. When installed, one end of the module heat sink abuts against the metal cover plate 212, and the other end abuts against the heating element of the driving board 230, so as to conduct heat.

[0055] In a possible implementation, the driving board 230 and the control board 220 are supported by copper pillars 260, one end of each copper pillar 260 is connected to the grounding point on the control board 220 via a screw, and the other end is connected to the grounding point on the driving board 230 respectively via internal thread insert nuts.

[0056] Specifically as Figure 2 and Figure 3As shown, in this embodiment, there is a certain distance between the drive board 230 and the control board 220. The drive board 230 is installed at the bottom of the housing 211 by screws, while the control board 220 is mounted on the upper side of the drive board 230 by copper pillars 260. It should be noted that the internal threaded insert nut connected to the drive board 230 by screws happens to be a grounding point inside it. Therefore, when the top of the copper pillar 260 is connected to the grounding point of the control board 220, the drive board 230 and the control board 220 are grounded. Thus, when the control board 220 is grounded through a ground wire, the drive board 230 will also be in a grounded state.

[0057] In general, the drive board 230 has multiple grounding points inside, and these grounding points are all connected to the control board 220 through copper pillars 260, which facilitates the subsequent grounding of the drive board 230.

[0058] In one possible implementation, the drive board 230 is connected to the motor body 110 via a grounding plate 300. The grounding plate 300 is provided with a closed screw hole 310 and an open screw hole 320. The closed screw hole 310 is connected to the grounding point on the drive board 230 via a screw, and the open screw hole 320 is connected to the motor body 110 via a screw.

[0059] Specifically, such as Figure 10 As shown, the grounding plate 300 has a Z-shaped structure. One end is connected to the motor body 110 by a screw, and the other end is connected to one of the grounding points on the drive board 230. In this embodiment, the grounding point closest to the screw is preferred, that is, the grounding point connected to the copper column 260. This enables grounding connection between the motor body 110, the drive board 230, and the control board 220. When the control board 220 is grounded through the grounding wire, the entire motor body 110 and the drive board 230 are grounded.

[0060] In one possible implementation, an operation window 2121 is provided in the middle of the cover plate 212, and a removable sealing cover 2122 is provided at the operation window 2121.

[0061] Understandably, to facilitate operation and observation of the control panel 220 by operators, this embodiment provides an operation window 2121 on the cover plate 212 at the position corresponding to the operation panel of the control panel 220, and provides a sealing cover 2122 that can be freely installed or removed, as detailed below. Figure 8 As shown; of course, the size and shape of the operation window 2121 and the sealing cover 2122 can be adjusted according to the actual situation, and this article does not make specific limitations here.

[0062] In one possible implementation, the two ends of the housing 211 are respectively provided with a closed fixing hole 2112 and an open fixing hole 2113, and the two ends of the housing 211 are provided with guide grooves 2114 for guiding screws into the closed fixing hole 2112 and the open fixing hole 2113. The closed fixing hole 2112 and the open fixing hole 2113 are used to pass screws through to fix the housing 211 to the motor body 110.

[0063] Specifically, such as Figure 6 and Figure 7 As shown, the housing 211 is connected to the motor body 110 through the closed fixing holes 2112 and the open fixing holes 2113 at both ends. During installation, the closed fixing holes 2112 of the housing 211 are first fixed with screws, and then the ends of the open fixing holes 2113 are fixed with screws. This design ensures that even if the housing 211 has dimensional errors in the length direction, the controller module 200 can be installed and fixed smoothly and quickly. Furthermore, a guide groove 2114 is provided on the upper side of the closed fixing holes 2112 and the open fixing holes 2113, which is recessed towards the inside of the housing 211. This design makes the housing 211 more compact and aesthetically pleasing, and can also guide the screws to pass through the closed fixing holes 2112 or the open fixing holes 2113.

[0064] In one possible implementation, the lower side of the cover plate 212 is provided with a fixing hole 2123 for fixing the cable 400, and the upper edge of the box body 211 is provided with a fixing groove 2115 for cooperating with the fixing hole 2123.

[0065] In this embodiment, the control board 220 is connected to an external power source or other control source via a cable 400. Therefore, in order to make the overall structure of the controller module 200 more compact and to fix the cable 400, this embodiment provides two fixing holes 2123 for the cable 400 to pass through on the lower edge of one side of the cover plate 212. At the same time, the side wall of the box 211 has a corresponding channel and a fixing slot 2115 that can be engaged with the fixing holes 2123 is also provided on the side wall. This arrangement allows the cable 400 to be stably engaged after the cover plate 212 and the box 211 are installed, so that it will not shake and thus will not affect its connection with the control board 220.

[0066] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0067] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0068] The embodiments provided by this utility model have been described in detail above.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
