[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] The following is for reference. Figures 1 to 6 The servo motor controller of this application is described in detail.

[0037] refer to Figure 1 and Figure 2 The servo motor controller according to an embodiment of the present utility model includes a housing 100, a circuit board assembly 200, and a mounting component 300.

[0038] The housing 100 has an internal cavity; the circuit board assembly 200 is disposed in the cavity, the circuit board assembly 200 includes a plurality of circuit boards 210 stacked along a preset direction, and the surface of the circuit board 210 is provided with lugs 220; the mounting member 300 is disposed on the periphery of the circuit board 210, and each circuit board 210 in the circuit board assembly 200 has at least one lug 220 connected to the mounting member 300 by a threaded connector.

[0039] For example, such as Figures 1 to 5As shown in the figure, the servo motor controller comprises a housing 100, a circuit board set 200 and a mounting piece 300, the housing 100 is formed with a receiving cavity, the circuit board set 200 comprises a plurality of circuit boards 210 stacked along the left-right direction, and the plurality of circuit boards 210 of the circuit board set 200 are stacked along the left-right direction, the board surface of each circuit board 210 is provided with a lug 220, the mounting piece 300 is provided along the left-right direction and is arranged at the common circumferential side of each circuit board 210 of the circuit board set 200, the mounting piece 300 is provided with a penetrating hole 310, a threaded connecting piece is penetratingly arranged in the penetrating hole 310 of the mounting piece 300 and is threadedly connected with the lug 220 on the circuit board 210, and the mounting piece 300 is mounted on the cavity wall of the receiving cavity through a threaded fixing piece.

[0040] It can be understood that when the circuit board 210 is installed, the worker can stack and distribute each circuit board 210 in the circuit board set 200 along the left-right direction, and then install the lug 220 on each circuit board 210 on the mounting piece 300 through the threaded connecting piece, so as to complete the installation of the circuit board set 200 on the mounting piece 300.

[0041] Since the lug 220 is arranged on the board surface of the circuit board 210, and the lug 220 on each circuit board 210 is connected with the mounting piece 300 through a separate threaded connecting piece, the single threaded connecting piece only needs to realize the connection between the single lug 220 and the mounting piece 300, the length of the threaded connecting piece can be selected to be shorter, and correspondingly, the difficulty of the threaded connecting piece breaking during the use of the servo motor controller of the present application is higher, thereby prolonging the service life of the servo motor controller of the present application.

[0042] In some embodiments of the present application, the lug 220 is provided with a clamping protrusion 221a, and the board surface of the circuit board 210 is provided with a clamping hole, and the clamping protrusion 221a is clamped in the clamping hole.

[0043] For example, as shown in the figure, the lug 220 is provided with two clamping protrusions 221a, and the board surface of the circuit board 210 is provided with two clamping holes, and the two clamping protrusions 221a of the lug 220 are clamped in the two clamping holes on the circuit board 210. Figure 4

[0044] It can be understood that when the lug 220 is installed on the circuit board 210, the worker can quickly install the lug 220 on the circuit board 210 by clamping the clamping protrusion 221a of the lug 220 in the clamping hole of the circuit board 210.

[0045] ​In order to improve the firmness of the lug 220 on the circuit board 210, in some embodiments of the present invention, after the snap-fit ​​protrusion 221a of the lug 220 passes through the snap-fit ​​hole on the circuit board 210, the operator can weld the snap-fit ​​protrusion 221a to the hole wall of the snap-fit ​​hole.

[0046] In some embodiments of this utility model, the lug 220 includes a first snap-fit ​​portion 221, a mounting portion 222, and a second snap-fit ​​portion 223 connected in sequence. The first snap-fit ​​portion 221, the mounting portion 222, and the second snap-fit ​​portion 223 together define a receiving groove 220a. Snap-fit ​​protrusions 221a are formed on both the first snap-fit ​​portion 221 and the second snap-fit ​​portion 223. The mounting portion 222 is provided with a threaded hole 222a, and a threaded connector passes through the threaded hole 222a.

[0047] For example, such as Figure 4 As shown, the lug 220 includes a first snap-fit ​​portion 221, a mounting portion 222, and a second snap-fit ​​portion 223 connected in sequence. Both the first snap-fit ​​portion 221 and the second snap-fit ​​portion 223 extend horizontally, with the first snap-fit ​​portion 221 located above the second snap-fit ​​portion 223. The mounting portion 222 extends vertically. The front end of the first snap-fit ​​portion 221 is smoothly connected to the upper end of the mounting portion 222, and the front end of the second snap-fit ​​portion 223 is smoothly connected to the lower end of the mounting portion 222, so that the first snap-fit ​​portion 221, the mounting portion 222, and the second snap-fit ​​portion 223 together form a receiving groove 220a. The left end of the first snap-fit ​​portion 221 and the second snap-fit ​​portion 223 are respectively provided with a snap-fit ​​protrusion 221a, and the mounting portion 222 is provided with a threaded hole 222a extending forward and backward.

[0048] It should be noted that the threaded connector includes a head and a shank that are connected. When the lug 220 and the mounting part 300 are connected, the shank of the threaded connector passes through the through hole 310 of the mounting part 300 and is threadedly connected to the wall of the threaded hole 222a on the mounting part 222.

[0049] It is understandable that the U-shaped shape of the lug 220 results in higher overall strength.

[0050] It is understandable that, since the first snap-fit ​​part 221, the mounting part 222 and the second snap-fit ​​part 223 together form the receiving groove 220a, the part of the shank of the threaded connector that protrudes from the threaded hole 222a can be accommodated in the receiving groove 220a, so as to protect the threaded connector.

[0051] It is understandable that, since the first snap-fit ​​portion 221 and the second snap-fit ​​portion 223 are respectively provided with snap-fit ​​protrusions 221a, when the lug 220 is subjected to load and deforms, the first snap-fit ​​portion 221 and the second snap-fit ​​portion 223 will deform first. Since the rod of the threaded connector is located in the receiving groove 220a, the rod of the threaded connector can support the groove wall of the receiving groove 220a, thereby reducing the deformation of the first snap-fit ​​portion 221 and the second snap-fit ​​portion 223, and further improving the strength of the lug 220.

[0052] In some embodiments of this utility model, reference is made to Figure 4 A boss 222b is formed on the mounting part 222, and a threaded hole 222a is provided on the boss 222b.

[0053] It should be noted that, due to the low thickness of the mounting part 222, after the connection between the mounting part 222 and the mounting part 300 is achieved by the threaded connector, the area of ​​the mounting part 222 near the threaded hole 222a will bear greater stress, which makes the mounting part 222 prone to tearing from the threaded hole 222a.

[0054] In the servo motor controller of this utility model, by providing a boss 222b on the mounting part 222 and setting the threaded hole 222a on the boss 222b, the thickness of the boss 222b is greater and the structural strength of the boss 222b is higher, thereby reducing the probability of tearing at the edge of the threaded hole 222a and extending the service life of the lug 220.

[0055] In some embodiments of the present invention, reference is made to Figure 2 The servo motor controller also includes an insulating plate 400. An insulating plate 400 is provided between any two adjacent circuit boards 210, and the insulating plate 400 is connected to the mounting component 300.

[0056] It is understandable that by placing an insulating plate 400 between any two adjacent circuit boards 210, the insulating plate 400 can separate the two adjacent circuit boards 210, thereby reducing the mutual interference between the two adjacent circuit boards 210.

[0057] To facilitate the connection between the insulating plate 400 and the mounting component 300, in some embodiments of this utility model, the mounting component 300 is provided with a slot 320, and the insulating plate 400 is at least partially engaged in the slot 320.

[0058] For example, such as Figure 5 As shown, a slot 320 is provided on the mounting component 300, and the edge of the insulating plate 400 is engaged in the slot 320.

[0059] It is understandable that by providing a slot 320 on the mounting component 300, and having the edge of the insulating plate 400 engaged within the slot 320, the installation and removal of the insulating plate 400 on the mounting component 300 becomes simpler and more convenient.

[0060] In some embodiments of this utility model, multiple mounting members 300 are provided, and the multiple mounting members 300 are distributed at intervals along the peripheral edge of the circuit board 210.

[0061] For example, such as Figure 2 As shown, the circuit board 210 is rectangular, and four mounting parts 300 are provided. The four mounting parts 300 are respectively located near the four corners of the circuit board 210. Each of the four corners of the circuit board 210 is provided with a lug 220. The lugs 220 at the four corners of the circuit board 210 are respectively connected to the four mounting parts 300 through threaded connectors.

[0062] It is understandable that by setting multiple mounting parts 300, the circuit boards 210 in the circuit board group 200 can be connected more firmly through the mounting parts 300, so that the circuit boards 210 in the circuit board group 200 can form a whole through the mounting parts 300.

[0063] In some embodiments of this utility model, the receiving cavity includes a first receiving sub-cavity and a second receiving sub-cavity, and the circuit board group 200 is disposed in the first receiving sub-cavity; the servo motor controller also includes a power supply 500, which is disposed in the second receiving sub-cavity, and the power supply 500 is electrically connected to each circuit board 210 respectively.

[0064] For example, such as Figure 2 and Figure 6 As shown, the receiving cavity includes a first receiving sub-cavity and a second receiving sub-cavity distributed along the front-back direction. The circuit board group 200 is located in the first receiving sub-cavity, and the power supply 500 of the servo motor controller is located in the second receiving sub-cavity. The power supply 500 is electrically connected to each circuit board 210 through wires.

[0065] It is understood that by placing the power supply 500 and the circuit board assembly 200 in the first and second accommodating sub-cavities respectively, the mutual interference between the power supply 500 and the circuit board assembly 200 can be reduced, thereby improving the safety factor of the servo motor controller of this utility model.

[0066] In a further embodiment of the present invention, the outer shell 100 includes a top plate 110, a bottom plate 120, a first L-shaped side plate 130, a second L-shaped side plate 140, a partition side plate 150, and a U-shaped side plate 160. The top plate 110, bottom plate 120, first L-shaped side plate 130, second L-shaped side plate 140, and partition side plate 150 together form a first receiving sub-cavity, and the top plate 110, bottom plate 120, partition side plate 150, and U-shaped side plate 160 together form a second receiving sub-cavity.

[0067] For example, such as Figure 1 , Figure 2 and Figure 6 As shown, the outer casing 100 includes a top plate 110, a bottom plate 120, a first L-shaped side plate 130, a second L-shaped side plate 140, a partition side plate 150, and a U-shaped side plate 160 that are spliced ​​together. The top plate 110 is located on the upper side of the receiving cavity to form the upper cavity wall of the receiving cavity, and the bottom plate 120 is located on the lower side of the receiving cavity to form the lower cavity wall of the receiving cavity. The first L-shaped side plate 130 is partially located on the left side of the first receiving sub-cavity and partially located on the front side of the first receiving sub-cavity. The portion of the first L-shaped side plate 130 located on the left side of the first receiving sub-cavity forms the left cavity wall of the first receiving sub-cavity. The second L-shaped side plate 140 is partially located on the right side of the first receiving sub-cavity and partially located on the front side of the first receiving sub-cavity. The portion of the second L-shaped side plate 140 located on the right side of the first receiving sub-cavity forms the right cavity wall of the first receiving sub-cavity. The portion of the second L-shaped side plate 140 located in front of the first receiving sub-cavity and the portion of the first L-shaped side plate 130 located in front of the first receiving sub-cavity together constitute the front cavity wall of the first receiving sub-cavity. A partition plate is disposed between the first receiving sub-cavity and the second receiving sub-cavity, and the partition plate constitutes the rear cavity wall of the first receiving sub-cavity and the front cavity wall of the second receiving sub-cavity, respectively. The U-shaped side plate 160 is located partly on the left side, partly on the rear side, and partly on the right side of the second receiving sub-cavity. The portion of the U-shaped side plate 160 located on the left side of the second receiving sub-cavity constitutes the left cavity wall of the second receiving sub-cavity. The portion of the U-shaped side plate 160 located on the rear side of the second receiving sub-cavity constitutes the rear cavity wall of the second receiving sub-cavity. The portion of the U-shaped side plate 160 located on the right side of the second receiving sub-cavity constitutes the right cavity wall of the second receiving sub-cavity.

[0068] It should be noted that, since the outer shell 100 has a first receiving sub-cavity and a second receiving sub-cavity inside, if the outer shell 100 is manufactured by integral molding, the manufacturing difficulty of the outer shell 100 will be high and the manufacturing cost will be high.

[0069] It is understood that in the servo motor controller of this utility model, the outer shell 100 is spliced ​​together from a top plate 110, a bottom plate 120, a first L-shaped side plate 130, a second L-shaped side plate 140, a partition side plate 150, and a U-shaped side plate 160. The structure of the top plate 110, bottom plate 120, first L-shaped side plate 130, second L-shaped side plate 140, partition side plate 150, and U-shaped side plate 160 is simple, and the difficulty of integral molding is relatively low, thereby reducing the overall manufacturing cost of the outer shell 100.

[0070] In some embodiments of this utility model, the servo motor controller further includes a heat dissipation component 600, which is disposed on the base plate 120. The preset direction is horizontal. The heat dissipation component 600 includes a plurality of cooling fans 610, and at least one cooling fan 610 is respectively provided directly below the circuit board assembly 200 and the power supply 500.

[0071] For example, such as Figure 2 and Figure 6 As shown, the servo motor controller also includes a heat dissipation assembly 600, which is mounted on a base plate 120 and includes three cooling fans 610, two of which are located at the lower end of the first receiving sub-cavity and one of which is located at the lower end of the second receiving sub-cavity.

[0072] Understandably, since the circuit boards 210 of the circuit board assembly 200 are stacked horizontally, a vertically extending heat dissipation channel is formed between any two adjacent circuit boards 210. The cooling fan 610 located in the first receiving sub-cavity can blow air upward to remove the heat in the heat dissipation channel, thereby cooling down each circuit board 210. The cooling fan 610 located in the second receiving sub-cavity can blow air upward to remove the heat on the power supply 500, thereby cooling down the power supply 500.

[0073] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
