[0035] At present, the volume of servo drives is getting smaller and smaller, especially for single-board servo drives. Due to the large number of communication interfaces, I / O interfaces, input and output interfaces, etc., all interfaces cannot be arranged on the front and rear end covers. Usually, interfaces are arranged on the upper and lower sides of the drive. In this way, the housing of the drive usually adopts a split structure, divided into an upper shell and a lower shell. The upper shell is clamped on the lower shell. However, in order to avoid input and output interfaces and the like, openings are made on the clamping side of the upper shell, which reduces the bending strength of the housing. After the upper shell and the lower shell are clamped, the opening part is prone to deformation.

[0036] The present utility model proposes a servo drive 100.

[0037] Please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the servo driver 100 includes a housing assembly 10 and a driving main board. The housing assembly 10 includes a first housing 20 and a second housing 30. At least one of the first housing 20 and the second housing 30 is provided with a side plate, and an opening 40 is provided on the side plate. The second housing 30 covers the first housing 20, and an installation cavity and an installation opening are formed by enclosing the second housing 30, the first housing 20 and the side plate; the driving main board includes a main board body and a connector. The main board body is electrically connected to the connector. The main board body is disposed in the installation cavity, and the connector is disposed in the installation opening; a first buckling portion is provided at a position of the side plate close to the opening 40, and a second buckling portion is provided at a position of the first housing 20 or the second housing 30 corresponding to the first buckling portion. The first buckling portion and the second buckling portion are buckled and connected;

[0038] The technical solution of the present utility model includes a housing assembly 10 and a driving main board. The housing assembly 10 includes a first housing 20 and a second housing 30. In this embodiment, a side plate can be provided on the first housing 20 or the second housing 30, or side plates can be provided on both the first housing 20 and the second housing 30 at the same time, and an opening 40 is provided on the side plate, so that an installation cavity and an installation opening which are connected and communicated are formed after the first housing 20, the second housing 30 and the side plate are covered. The installation cavity is used for installing the main board body in the driving main board, and the installation opening is used for installing the connector electrically connected to the main board body. The main board body is electrically connected to an external device through the connector. In this embodiment, the side plate can be integrally formed with the first housing 20 and / or the second housing 30, or can be connected by fasteners later, and no excessive limitation is made on this. Since an opening 40 is provided on the side plate as the installation opening, in order to improve the bending resistance and clamping strength when the side plate is connected, in this embodiment, a first buckling portion is provided at a position of the side plate close to the opening 40, and a second buckling portion is provided at a position of the first housing 20 or the second housing 30 corresponding to the first buckling portion, so that the first buckling portion and the second buckling portion are buckled and connected. Providing a buckling portion at a position of the side plate close to the opening 40 can effectively improve the bending resistance and clamping strength when the side plate is connected to the first housing 20 or the second housing 30.

[0039] In one embodiment, the side plates include a first side plate 21 and a second side plate 31. Among them, the first housing 20 has the first side plate 21, the second housing 30 has a second side plate 31 that fits against the first side plate 21. The second side plate 31 is located on the side of the first side plate 21 facing away from the installation cavity. The first fastening portion is provided on the side of the first side plate 21 facing the second side plate 31, and the second fastening portion is provided on the side of the second side plate 31 facing the first side plate 21. In this embodiment, the first housing 20 is provided with the first side plate 21, and the first fastening portion is provided on the first side plate 21. The second housing 30 is provided with a second fastening portion on the second side plate 31. Among them, the first fastening portion is provided on the side of the first side plate 21 facing the second side plate 31, and the second fastening portion is provided at a position corresponding to the first fastening portion on the side of the second side plate 31 facing the first side plate 21. Therefore, when the second housing 30 is closed onto the first housing 20, the second housing 30 and the first housing 20 will enclose to form an installation cavity. Since the first housing 20 is provided with the first side plate 21 and the first fastening portion is provided on the first side plate 21, and the second housing 30 is provided with the second side plate 31, and the second fastening portion is provided at a position on the side of the second side plate 31 facing the first side plate 21 and corresponding to the first fastening portion. Therefore, when the second housing 30 is closed onto the first housing 20, the first fastening portion slides into the second fastening portion along the side wall of the second side plate 31 to achieve fastening. In this embodiment, since the second side plate 31 of the second housing 30 is sleeved outside the first side plate 21 of the first housing 20, that is to say, the second side plate 31 is sleeved on the outer periphery of the first side plate 21. And because the first fastening portion protrudes from the side of the first side plate 21 facing the second side plate 31, and the second fastening portion is provided at a position on the side of the second side plate 31 facing the first side plate 21 and corresponding to the first fastening portion. When the second housing 30 is covered on the first housing 20, the first fastening portion is fastened in the second fastening portion. At this time, the first fastening portion does not protrude from the second side plate 31, forming a hidden fastening. An opening 40 for installing an interface is provided on the first side plate 21 and / or the second side plate 31. The first fastening portion and / or the second fastening portion is provided on one side or both sides of the opening 40.Since it is necessary to install electronic components in the installation cavity formed by enclosing the first housing 20 and the second housing 30, corresponding wiring terminals need to be provided for electrical connection with the electronic components. Since the existing interfaces provided at the front end or the rear end of the installation cavity are insufficient, interfaces are opened on the side of the installation cavity. Opening the structure on the side will cause the connection strength between the first housing 20 and the second housing 30 to decrease. In this embodiment, an opening 40 for installing the wiring terminal is opened on the first housing 20 or the second housing 30, or partial openings 40 are opened on both the first housing 20 and the second housing 30 at the same time. After the two are covered and connected, the partial openings 40 enclose to form the complete installation opening as described above. Since the first fastening portion and the second fastening portion are arranged in a hidden manner, such an arrangement not only has the characteristics of small size and free position.

[0040] In one embodiment, the first fastening portion provided on the first side plate 21 of the first housing 20 is a first protruding portion 213, and the second fastening portion provided on the second side plate 31 of the second housing 30 is a first groove 311. Among them, the first protruding portion 213 is provided on the side of the first side plate 21 facing the second side plate 31, while the first groove 311 is provided on the side of the second side plate 31 facing the first side plate 21 and at a position corresponding to the first protruding portion 213. Therefore, when the second housing 30 is covered on the first housing 20, the second housing 30 and the first housing 20 will enclose an installation cavity, which can be used to install other electrical components or electronic devices, etc. Since the first housing 20 is provided with the first side plate 21 and the first protruding portion 213 is provided on the first side plate 21, and the second housing 30 is provided with the second side plate 31, and a first groove 311 is opened on the side of the second side plate 31 facing the first side plate 21 and at a position corresponding to the first protruding portion 213, when the second housing 30 is covered on the first housing 20, the first protruding portion 213 slides into the first groove 311 along the side wall of the second side plate 31 to achieve fastening. In this embodiment, since the second side plate 31 of the second housing 30 is sleeved on the outside of the first side plate 21 of the first housing 20, that is, the second side plate 31 is sleeved on the outer periphery of the first side plate 21, and because the first protruding portion 213 protrudes from the side of the first side plate 21 facing the second side plate 31, and a first groove 311 is opened on the side of the second side plate 31 facing the first side plate 21 and at a position corresponding to the first protruding portion 213, when the second housing 30 is covered on the first housing 20, the first protruding portion 213 is fastened in the first groove 311. At this time, the first protruding portion 213 does not protrude from the second side plate 31, forming a hidden fastening. Such a setting of the first protruding portion 213 on the first side plate 21 and the first groove 311 on the second side plate 31 can improve the bending strength of the first side plate 21 and the second side plate 31 on the first housing 20 and the second housing 30, and the two are hiddenly arranged with the characteristics of small size and free position, which can effectively strengthen the clamping strength after the first housing 20 and the second housing 30 are assembled.

[0041] Specifically, as Figure 2 and Figure 4 shown, the depth of the first groove 311 is less than the thickness of the second side plate 31. In this embodiment, to ensure the self-strength of the second side plate 31, in this embodiment, the depth of the first groove 311 is set to be less than the thickness of the second side plate 31. Such a setting can more perfectly achieve the above-mentioned hidden design, and it can also effectively avoid opening through holes on the second side plate 31, resulting in a decrease in the structural strength of the second side plate 31 itself.

[0042] In one embodiment, as Figure 3As shown, the first side plate 21 includes a first support section 211 and a second support section 212. The first support section 211 is disposed on the second support section 212. The thickness of the first support section 211 is less than that of the second support section 212, so as to define a support platform 214 between the edges of the first support section 211 and the second support section 212. One side of the second side plate 31 is supported on the support platform 214. In this embodiment, the first side plate 21 includes the first support section 211 and the second support section 212. The first support section 211 and the second support section 212 may be integrally formed, or they may be fixedly connected by fasteners. There is no excessive limitation on this. The thickness of the first support section 211 is less than that of the second support section 212, and the first support section 211 is disposed at the end of the second support section 212 away from the first housing 20. Since the thickness of the first support section 211 is less than that of the second support section 212, the first support section 211 does not completely occupy the end face of the second support section 212 away from the first housing 20. The end face and the side of the first support section 211 away from the installation cavity define the support platform 214. When the second housing 30 is covered on the first housing 20, one end of the second side plate 31 away from the second housing 30 will be supported on the support platform 214. By such a setting, the second side plate 31 can be supported and clamped on the first side plate 21 more stably and firmly, so that the connection between the first housing 20 and the second housing 30 is more stable and firm. In other embodiments, similarly, to enable the first side plate 21 to have a supporting effect on the second side plate 31, a protruding platform may be convexly provided at one end of the first side plate 21 away from the installation cavity. The protruding platform is mainly used to support the second side plate 31.

[0043] Specifically, the first protrusion 213 is disposed on the first support section 211. The first protrusion 213 and the support platform 214 enclose a second groove 2111. A second protrusion 313 is formed between one end of the second side plate 31 and the first groove 311. The second protrusion 313 is limited in the second groove 2111. In this embodiment, since the first protrusion 213 protrudes from the first support section 211 in the direction away from the installation cavity, the first protrusion 213 and the support platform 214 enclose a second groove 2111. Secondly, as Figure 4 shown, a second protrusion 313 is formed between one end of the second side plate 31 away from the second housing 30 and the first groove 311. When the second housing 30 is covered on the first housing 20 and the first protrusion 213 is buckled in the first groove 311, the second protrusion 313 will be buckled in the second groove 2111 at the same time. By such a setting, the connection firmness effect between the second housing 30 and the first housing 20 can be further improved.

[0044] In one embodiment, asFigure 3 As shown, on the side of the first protruding portion 213 facing the second side plate 31 from the first side plate 21, there is a first guiding surface 2131 for the first protruding portion 213 to slide into the first groove 311. In order to make the insertion of the first protruding portion 213 into the first groove 311 smoother, in this embodiment, a first guiding surface 2131 is provided on the side of the first protruding portion 213 facing the second side plate 31. The first guiding surface 2131 can be inclined or arc-shaped. The first guiding surface 2131 can pass through the second protruding portion 313 described in the above embodiment more smoothly when the first protruding portion 213 slides into the first groove 311. Through such a setting, the first protruding portion 213 can be more smoothly installed into the first groove 311, enabling the second housing 30 and the first housing 20 to be snap-connected.

[0045] Specifically, the first guiding surface 2131 is inclined in the direction from the first protruding portion 213 towards the first side plate 21, and the thickness of the first protruding portion 213 is gradually enlarged in the direction towards the first side plate 21. In this embodiment, the first guiding surface 2131 is inclined, and the first guiding surface 2131 is inclined in the direction from the first protruding portion 213 towards the first side plate 21, and the thickness of the first protruding portion 213 is gradually enlarged in the direction towards the first side plate 21. Here, the thickness refers to the dimension of the first protruding portion 213 along the extending direction of the first side plate 21. Since the first protruding portion 213 needs to abut against the second protruding portion 313 when sliding into the first groove 311, and the first protruding portion 213 can more smoothly slide into the first groove 311 through the second protruding portion 313, so setting the end face of the first protruding portion 213 facing the second side plate 31 to be inclined can effectively reduce the resistance when the first protruding portion 213 abuts against the second protruding portion 313. Of course, in other embodiments, in order to further improve the effect of the first protruding portion 213 detaching from the first groove 311, the end of the first protruding portion 213 facing the support platform 214 can be inclined or arc-shaped. Such a setting can effectively improve the smoothness of the first protruding portion 213 when detaching from the first groove 311, and an inclined surface or arc-shaped surface adapted to the end of the first protruding portion 213 facing the support platform 214 can also be provided in the first groove 311.

[0046] In another embodiment, the end of the first protruding portion 213 away from the first side plate 21 is arc-shaped. Similarly, in order to make the first protruding portion 213 slide into the first groove 311 more smoothly, therefore, in this embodiment, the end of the first protruding portion 213 away from the first side plate 21 is arc-shaped, which can also effectively reduce the resistance between the first protruding portion 213 and the second protruding portion 313 when the first protruding portion 213 slides into the first groove 311.

[0047] In one embodiment, asFigure 2 , Figure 4 , Figure 5 and Figure 6 As shown in Figure 5 , Figure 6 , at one end of the second side plate 31 away from the second housing 30, a second guiding surface 312 is provided, and the second guiding surface 312 is arranged on the side surface of the second side plate 31 facing the first side plate 21. Similar to the above embodiment, in order to enable the first protruding portion 213 to enter the first groove 311 more smoothly through the second protruding portion 313, in this embodiment, a second guiding surface 312 is provided at one end of the second side plate 31 away from the second housing 30, and the second guiding surface 312 is arranged on the side surface of the second side plate 31 facing the first side plate 21. In this embodiment, the second guiding surface 312 can also be arranged in an inclined or arc shape. For example, the second guiding surface 312 is a chamfer at one end of the second side plate 31 away from the second housing 30, and the chamfer is arranged on the side of the second side plate 31 facing the first side plate 21.

[0048] Specifically, the second guiding surface 312 is an inclined surface, one end of the inclined surface is in transitional connection with the end surface of the second side plate 31 away from the second housing 30, and the other end of the inclined surface is in transitional connection with the end surface of the second side plate 31 facing the first side plate 21. In this embodiment, the second guiding surface 312 is arranged in an inclined surface shape, where one end of the inclined surface is in smooth transitional connection with the end surface of the second side plate 31 away from the second housing 30, and the other end is in smooth transitional connection with the end surface of the second side plate 31 facing the first side plate 21. That is to say, the inclined surface gradually approaches the first side plate 21 and the installation cavity along the direction from the second side plate 31 to the second housing 30, that is, the distance from the first side plate 21 and the installation cavity is gradually reduced. The second guiding surface 312 arranged in this way can guide the first protruding portion 213. In other embodiments, the second guiding surface 312 in this embodiment and the first guiding surface in the above embodiment can be used in the same embodiment, and no more limitations are made in this regard.

[0049] In one embodiment, as shown in Figure 1As shown, one of the first housing 20 and the second housing 30 is provided with a buckle 50, and the other is provided with a notch 60. The notch 60 is correspondingly formed for the buckle 50, and the notch 60 is buckled with the buckle 50. To further improve the connection strength between the first housing 20 and the second housing 30, in this embodiment, a buckle 50 is also provided on one side of the first housing 20 and the second housing 30, and a notch 60 is provided on the other side. The notch 60 is correspondingly formed for the buckle 50, and the notch 60 is used to be buckled with the buckle 50. For example, the buckle 50 is protrudingly provided on the first housing 20, and the notch 60 is formed on the second side plate 31 of the second housing 30. When the second housing 30 is closed on the first housing 20, the buckle 50 is inserted into the notch 60, making the buckling between the second housing 30 and the first housing 20 more stable. Secondly, considering the convenience of disassembling the first housing 20 and the second housing 30, in this embodiment, a side groove 70 is also formed on the second housing 30. The side groove 70 is provided at one end of the second side plate 31 of the second housing 30 away from the second housing 30, and the side groove 70 is provided directly below the notch 60. When it is necessary to disassemble the second housing 30 from the first housing 20, a tool can be inserted into the side groove 70, and then the second side plate 31 of the second housing 30 can be pried up, so that the buckle 50 is disengaged from the notch 60 and the first protrusion 213 is disengaged from the first groove 311. Then, the second housing 30 can be manually taken out from the first housing 20.

[0050] The present utility model also provides a servo system, which includes a servo driver 100 as described in any of the above embodiments.
