Description

Technical Field

[0001] This case is about a driver assembly structure, in particular a parallel modular driver assembly structure. Background Art

[0002] Automation equipment has evolved from improving production efficiency to further developing intelligence, enabling the equipment to respond to emergency situations with self-judgment and predict the next behavior through big data. Such rapid progress will make the configuration of components in the control panel of the data analysis equipment from the front-end information reception to the back-end more complex. In the control panel, space utilization is one of the competitive indicators of the product, especially the driver occupies most of the volume in the control panel, so the development of a driver assembly structure that is easy to expand, assemble and apply has become the current research and development focus.

[0003] Drivers widely include rectifiers, inverters, frequency converters, servo controllers, IO modules, communication modules, etc. The frequency converter controls and drives the motor by converting the frequency and voltage through AC input. The AC input may have different voltage specifications according to different customer needs, and even the same device may have different working voltage designs. The conversion between DC and AC in a stand-alone frequency converter is designed on the same circuit board or in the same device. Modular frequency converters are different from previous stand-alone frequency converters. The conversion between DC and AC is divided into two components, called rectifier units and inverter units. Customers need to purchase equipment according to their own needs and install and splice them by themselves.

[0004] However, rectifier units or inverter units with different operating voltage specifications often have similar appearance and structure. If you are not careful during assembly, you may mistakenly insert modular inverters with different operating voltages, which may cause the risk of power-on damage to the equipment.

[0005] In view of this, it is necessary to develop an improved parallel modular driver assembly structure to solve the deficiencies and problems of the prior art. Utility Model Content

The parallel driver assembly structure can be realized between any two adjacent modules through a modular guide structure. The following first describes the combination changes provided by the parallel modular driver assembly structure of the present invention.

[0057] Please refer to Figure 1A and Figure 1B . The parallel modular driver assembly structure of the present case provides a first driver combination 220, including a first module 1 and at least one second module 2, and the first module 1 and at least one second module 2 are arranged along a first direction (i.e., the X-axis direction), and the first module 1 and at least one second module 2 are assembled with each other along a second direction (i.e., the Y-axis direction). The first module 1 includes a shell C of the first module 1, a left guide structure GL of the first module 1, and a right guide structure GR of the first module, and the left guide structure GL and the right guide structure GR are respectively arranged on the left side SL of the shell C along the first direction and the right side SR of the shell C. Each second module 2 includes a shell C of the second module 2, a left guide structure GL of the second module 2, and a right guide structure GR of the second module 2, and the left guide structure GL and the right guide structure GR are respectively arranged on the left side SL of the shell C along the first direction and the right side SR of the shell C. The left guide structure GL of the first module 1 and the right guide structure GR of the first module 1 are extended along the second direction, and the left guide structure GL of the second module 2 and the right guide structure GR of the second module 2 are extended along the second direction. The first module 1 and the second module 2 are detachably connected and assembled with each other by the corresponding right guide structure GR of the first module 1 and the Y left guide structure GL of the second module 2 along the second direction, so that the first module 1 and the second module 2 are assembled. In this embodiment, the first module 1 is a rectifier unit with a working voltage of 220V, and the second module 2 is an inverter unit with a working voltage of 220V. In some embodiments, the first driver assembly 220 may include a first module 1 and two second modules 2, wherein the two second modules 2 are extended and assembled on two opposite sides of the first module 1, or the two second modules 2 are assembled with each other and then assembled to one side of the first module 1. It should be emphasized that the number of the second modules 2 and the expansion assembly method are not limited to the aforementioned embodiments, and can be changed according to actual application needs. In addition, the parallel modular driver assembly structure of the present invention further includes a back plate B, which is assembled simultaneously from the back of the first module 1 and at least one second module 2 along the second direction (ie, the Y-axis direction) to supply power to these modules for operation.

[0058] refer to Figure 2A This is a front view of the second driver combination of the parallel modular driver assembly structure of the first embodiment of the present case. Figure 2BThe exploded view of the second driver combination of the parallel modular driver assembly structure of the first embodiment of the present invention. The parallel modular driver assembly structure of the present invention provides a second driver combination 440, including a third module 3 and at least one fourth module 4, and the third module 3 and at least one fourth module 4 are arranged along the first direction (i.e., the X-axis direction), and the third module 3 and at least one fourth module 4 are assembled with each other along the second direction (i.e., the Y-axis direction). The third module 3 includes a shell C of the third module 3, a left guide structure GL of the third module 3, and a right guide structure GR of the third module 3, and the left guide structure GL and the right guide structure GR are respectively arranged on the left side SL of the shell C along the first direction and the right side SR of the shell C. Each fourth module 4 includes a shell C of the fourth module 4, a left guide structure GL of the fourth module 4, and a right guide structure GR of the fourth module 4, and the left guide structure GL and the right guide structure GR are respectively arranged on the left side SL of the shell C along the first direction and the right side SR of the shell C. The left guide structure GL of the third module 3 and the right guide structure GR of the third module 3 are extended along the second direction, and the left guide structure GL of the fourth module 4 and the right guide structure GR of the fourth module 4 are extended along the second direction. The third module 3 and the fourth module 4 are detachably connected and assembled with each other by the corresponding right guide structure GR of the third module 3 and the left guide structure GL of the fourth module 4 along the second direction, thereby realizing the combination of the third module 3 and the fourth module 4. In this embodiment, the third module 3 is a rectifier unit with a working voltage of 440V, and the fourth module 4 is an inverter unit with a working voltage of 440V. In some embodiments, the second driver combination 440 may include a third module 3 and two fourth modules 4, wherein the two fourth modules 4 are extended and assembled on two opposite sides of the third module 3, or the two fourth modules 4 are assembled with each other and then assembled to one side of the third module 3. It should be emphasized that the number and the expansion assembly method of the fourth module 4 are not limited to the aforementioned embodiments, and can be changed according to actual application needs. In addition, the parallel modular driver assembly structure of the present invention further includes a back plate B, which is assembled from the back of the third module 3 and at least one fourth module 4 along the second direction (ie, the Y-axis direction) to supply power to these modules for operation.

[0059] It should be noted that the first module 1 and at least one second module 2 of the aforementioned first driver combination 220, as well as the third module 3 and at least one fourth module 4 of the aforementioned second driver combination 440 are approximately allowed to be plugged into the modular backplane B along the second direction (i.e., the Y-axis direction). However, the operating voltages of the first driver combination 220 and the second driver combination 440 are different and are not compatible. In order to prevent incorrect combinations, so that installers can more friendly and intuitively judge whether they are assembled correctly, and at the same time reduce the assembly error rate, the multiple modules of the parallel driver combination of this case are further provided with different guide structures according to different operating voltages, thereby distinguishing incompatible modules through changes in the design of the guide structure, and avoiding damage to the modules due to misuse. The differences between the first driver combination 220 and the second driver combination 440 are further explained as follows.

[0060] Figure 4 This is an enlarged view of the P1 area of ​​the first driver combination of the parallel modular driver assembly structure of the first embodiment of this case. Figure 1A , Figure 1B and Figure 4In the first driver assembly 220, the right guide structure GR of the first module 1 and the left guide structure GL of the second module 2 are assembled along the second direction (i.e., the Y-axis direction) for illustration. The right guide structure GR of the first module 1 includes a guide groove Gs and a guide rib Gb adjacent to the guide groove Gs. Corresponding to the right guide structure GR of the first module 1, the left guide structure GL of the second module 2 respectively includes a structure of a convex portion Gp corresponding to the guide groove Gs, and a structure of a concave portion Gd corresponding to the guide rib Gb. In this embodiment, the guide groove Gs and the guide rib Gb are arranged along the first direction, and the guide groove Gs is between the shell C and the guide rib Gb. The guide groove Gs has a depth D1 that is the same as the height of the corresponding convex portion Gp, and the guide rib Gb has a height H1 that is the same as the depth of the corresponding concave portion Gd. In addition, in this embodiment, the guide groove Gs has a first width W1a which is the same as the width of the corresponding protrusion Gp, and the guide rib Gb has a second width W1b which is the same as the width of the corresponding recess Gd. Thus, the right guide structure GR of the first module 1 and the left guide structure GL of the second module 2 are allowed to be assembled along the second direction (i.e., the Y-axis direction). Similarly, the right guide structure GR of the second module 2 and the left guide structure GL of the first module 1 can also have the same size of the guide groove Gs, the guide rib Gb, the protrusion Gp and the recess Gd, so as to realize the assembly of these right guide structures GR and the corresponding left guide structures GL along the second direction (i.e., the Y-axis direction). In other words, in the first driver assembly 220, each of the right guide structure GR and the left guide structure GL of each of the first module 1 and the second module 2 has a guide groove Gs and an adjacent guide rib Gb, and the other has a structure of a convex portion Gp corresponding to the guide groove Gs, and a concave portion Gd corresponding to the guide rib Gb, so that the modules can be assembled with each other along the second direction using the right guide structures GR and the corresponding left guide structures GL. In this embodiment, the right guide structure GR disposed on the upper right of the shell C of the first module 1 is allowed to be assembled with the left guide structure GL disposed on the upper left of the shell C of the second module 2 along the second direction, and the right guide structure GR disposed on the lower right of the shell C of the first module 1 is also allowed to be assembled with the left guide structure GL disposed on the lower left of the shell C of the second module 2 along the second direction. Of course, in the first driver assembly 220, the right guide structures GR and the corresponding left guide structures GL can be adjusted according to the actual application requirements. The present case is not limited to this.

[0061] Figure 5 This is an enlarged view of the P2 area of ​​the second driver combination of the parallel modular driver assembly structure of the first embodiment of this case. Figure 2A , Figure 2B and Figure 5In the second driver assembly 440, the right guide structure GR of the third module 3 and the left guide structure GL of the fourth module 4 are assembled along the second direction (i.e., the Y-axis direction) for illustration. The right guide structure GR of the third module 3 includes a guide groove Gs and a guide rib Gb adjacent to the guide groove Gs. Corresponding to the right guide structure GR of the third module 3, the left guide structure GL of the fourth module 4 respectively includes a structure of a convex portion Gp corresponding to the guide groove Gs, and a structure of a concave portion Gd corresponding to the guide rib Gb. In this embodiment, the guide groove Gs and the guide rib Gb are arranged along the first direction, and the guide groove Gs is between the shell C and the guide rib Gb. The guide groove Gs has a depth D2 that is the same as the height of the corresponding convex portion Gp, and the guide rib Gb has a height H2 that is the same as the depth of the corresponding concave portion Gd. In addition, in this embodiment, the guide groove Gs has a first width W2a which is the same as the width of the corresponding protrusion Gp, and the guide rib Gb has a second width W2b which is the same as the width of the corresponding recess Gd. Thus, the right guide structure GR of the third module 3 and the left guide structure GL of the fourth module 4 are allowed to be assembled along the second direction (i.e., the Y-axis direction). Similarly, the right guide structure GR of the fourth module 4 and the left guide structure GL of the third module 3 may also have the same size of guide grooves Gs, guide ribs Gb, protrusions Gp and recesses Gd, so as to realize the assembly of these right guide structures GR and the corresponding left guide structures GL along the second direction (i.e., the Y-axis direction). In other words, in the second driver assembly 440, each of the right guide structure GR and the left guide structure GL of each of the third module 3 and the fourth module 4 has a guide groove Gs and an adjacent guide rib Gb, and the other has a structure of a convex portion Gp corresponding to the guide groove Gs, and a concave portion Gd corresponding to the guide rib Gb, so as to realize that these modules are assembled with each other along the second direction using these right guide structures GR and the corresponding left guide structures GL. In this embodiment, the right guide structure GR disposed on the upper right of the shell C of the third module 3 is allowed to be assembled with the left guide structure GL disposed on the upper left of the shell C of the fourth module 4 along the second direction, and the right guide structure GR disposed on the lower right of the shell C of the third module 3 is also allowed to be assembled with the left guide structure GL disposed on the lower left of the shell C of the fourth module 4 along the second direction. Of course, in the first driver assembly 220, the right guide structures GR and the corresponding left guide structures GL can be adjusted according to the actual application requirements. The present case is not limited to this.

[0062] It is worth noting that the depth D1 of these guide grooves Gs in the first driver combination 220 is less than the depth D1 of these guide grooves Gs in the second driver combination 440. The height H1 of these guide ribs Gb in the first driver combination 220 is less than the height H2 of these guide ribs Gb in the second driver combination 440. That is, the height of these protrusions Gp in the first driver combination 220 is less than the height of these protrusions Gp in the second driver combination 440. The depth of these recesses Gd in the first driver combination 220 is less than the depth of these recesses Gd in the second driver combination 440. In other words, the depth D1 of these guide grooves Gs in the first driver combination 220 (the height of these protrusions Gp) and the height H1 of these guide ribs Gb (the depth of these recesses Gd) are set according to the corresponding operating voltages of the first module 1 and the second module 2. The depth D2 of the guide grooves Gs (the height of the protrusions Gp) and the height H2 of the guide ribs Gb (the depth of the recesses Gd) in the second driver assembly 440 are set according to the operating voltages of the corresponding third module 3 and fourth module 4. In this way, when the operating voltages of the modules are different, the guide grooves Gs, guide ribs Gb, protrusions Gp and recesses Gd used for corresponding assembly have size differences in the Z-axis direction, and cannot be assembled in pairs.

[0063] On the other hand, the first width W1a of the guide grooves Gs in the first driver combination 220 is smaller than the first width W2a of the guide grooves Gs in the second driver combination 440. The second width W1b of the guide ribs Gb in the first driver combination 220 is smaller than the second width W2b of the guide ribs Gb in the second driver combination 440. That is, the width of the protrusions Gp in the first driver combination 220 is smaller than the width of the protrusions Gp in the second driver combination 440. The width of the recesses Gd in the first driver combination 220 is smaller than the width of the recesses Gd in the second driver combination 440. In other words, the first width W1a of the guide grooves Gs in the first driver combination 220 (the width of the protrusions Gp) and the second width W1b of the guide ribs Gb (the width of the recesses Gd) are set according to the corresponding operating voltages of the first module 1 and the second module 2. The first width W2a (the height of the protrusions Gp) of the guide grooves Gs and the second width W2b (the width of the recesses Gd) of the guide ribs Gb in the second driver assembly 440 are set according to the operating voltages of the corresponding third module 3 and fourth module 4. In this way, when the operating voltages of the modules are different, the guide grooves Gs, guide ribs Gb, protrusions Gp and recesses Gd used for corresponding assembly have size differences in the X-axis direction, and cannot be assembled in pairs.

[0064] refer to Figure 3AThis is an alignment diagram of the first module and the fourth module of the parallel modular driver assembly structure of the first embodiment of the present case. FIG. 3B to FIG. 3E This is an enlarged view of the P3 to P6 regions of the first module and the fourth module of the parallel modular drive assembly structure of the first embodiment of the present case. In this embodiment, for example, when the right guide structure GR of the fourth module 4 is aligned with the left guide structure GL of the first module 1 along the second direction, the guide rib Gb of the right guide structure GR of the fourth module 4 partially overlaps with the recessed portion Gd of the left guide structure GL of the first module 1, thereby generating assembly interference ( Figure 3B and Figure 3C ), achieving physical foolproofing, so that modules with different operating voltages cannot be assembled with each other. When the left guide structure GL of a fourth module 4 is aligned with the right guide structure GR of the first module 1 along the second direction, the convex portion Gp of the left guide structure GL of the fourth module 4 partially overlaps with the guide groove Gs of the right guide structure GR of the first module 1, resulting in assembly interference ( Figure 3D and Figure 3E ), achieving physical fool-proofing, and thus realizing applications where modules with different operating voltages cannot be assembled together.

[0065] It should be noted that the structure of the first module 1 and the second module 2 in the first driver assembly 220 is similar to the structure of the third module 3 and the fourth module 4 in the second driver assembly 440. The difference is only a slight change in size according to the corresponding working voltage of the module. In other words, the parallel modular driver assembly structure design of this case only needs to adjust the existing mold to repair the guide rib Gb, guide groove Gs, concave part Gd and convex part Gp. The processing is simple and does not require the replacement of the existing mold, which can reduce considerable costs and energy consumption.

[0066] Since the modules in the first driver assembly 220 or the second driver assembly 440 are assembled with the right guide structures GR and the corresponding left guide structures GL along the second direction (i.e., the Y direction), the parallel modular driver assembly structure of this case can change the shape of the guide ribs Gb and the guide grooves Gs on the XZ plane, so that the modules with the same working voltage value can be detachably connected to each other, and the modules with different working voltage values ​​can generate assembly interference during assembly and alignment to form a physical foolproof mechanism, so that more combinations of working voltage values ​​can be added and the same effect can be achieved. Of course, this case is not limited to this.

[0067] refer to Fig. 6AThis is an exploded view of the first module of the parallel modular drive assembly structure of the second embodiment of the present case. For example, the first module 1 includes a left unit UL, a right unit UR and a middle unit UM assembled along a first direction. The right guide structure GR is arranged above and below the right unit UR, and the left guide structure GL is arranged above and below the left unit UL. In other embodiments, the right guide structure GR and the left guide structure GL are arranged to cooperate with the assembly of the left unit UL, the right unit UR and the middle unit UM, and the present case is not limited to this.

[0068] refer to Figure 6B This is an exploded view of the shell of the second module of the parallel modular drive assembly structure of the second embodiment of the present case. For example, the second module 2 is assembled along the first direction by the left unit UL, the right unit UR and the middle unit UM. The left guide structure GL is set at the upper left and lower left of the middle unit UM, and the right guide structure GR is set at the upper right and lower right of the middle unit UM. This design can respond to the diversified deformation of the guide structure, realize the versatility of components, reduce mold development costs, and enhance product competitiveness. Similarly, the third module 3 and the fourth module 4 respectively include the left unit UL, the right unit UR and the middle unit UM, and can achieve the same effect.

[0069] In summary, the present invention provides a parallel modular drive assembly structure. A plurality of modules are detachably connected in parallel with each other, and can be expanded and assembled with required modules and quantity along a first direction according to application requirements. In addition, each of these modules has a housing, a left guide structure and a right guide structure, wherein the right guide structure is arranged on the right side of the housing along the first direction, and the left guide structure is arranged on the left side of the housing along the first direction. These modules are assembled with corresponding right guide structures and left guide structures along a second direction, and these modules are provided with different guide structures according to different working voltages, thereby distinguishing incompatible modules through design changes of the guide structure, preventing wrong combination, allowing the installer to more friendly and intuitively judge whether the assembly is correct, reducing the assembly error rate, and avoiding damage to the module. Furthermore, by disassembling each module into a plurality of units, and the guide structure is arranged in one of the plurality of units, or the guide structure is composed of a combination of a plurality of units, thereby responding to the diversified deformation of the guide structure, achieving the universality of components and reducing the mold development cost.
