[0038] In this application, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be internal communication between two elements, or it can be only surface contact.

[0039] In this embodiment, the control cabinet shell 10 is used to install the main controller 4012 and the expansion circuit board module 200. This specification does not limit the specific structure of the control cabinet shell 10. For example, the control cabinet shell 10 can have multiple installation spaces to install different components of the control device 300, and the side wall of the control cabinet shell 10 can also be provided with multiple slots and hole structures to pass wires or install sockets, operating buttons and other structures. In some embodiments, the control device 100 can also include other interfaces, such as network interfaces, hardware interfaces, etc., and can also include control buttons such as switches and knobs. These interfaces and control buttons can be installed on the side wall of the control cabinet shell 10. The expansion module area 12 is located at one end of the control cabinet shell 10, which is used to install the expansion circuit board module 200. The expansion module area 12 can be connected to other installation spaces in the control cabinet shell 10, so that the expansion circuit board module 200 in the expansion module area 12 is electrically connected to the main controller 4012.

[0040] The bracket 70 is arranged in the expansion module area 12, and the bracket 70 may include a body 74, and the expansion installation space 72 is arranged in the body 74. The body 74 has a bottom 741 and an opening 743 opposite to each other, and the expansion installation space 72 is connected to the outside through the opening 743. The bottom 741 is provided with a mounting groove 7412, so that the expansion circuit board module 200 in the expansion installation space 72 can be connected to the circuit board 30. The body 74 is generally arranged in a hollow frame, which not only ensures the structural strength, but also improves the heat dissipation effect of the expansion circuit board module 200.

[0041] The connection circuit board 30 is disposed in the control cabinet shell 10, and a portion of the connection circuit board 30 is overlapped on the bottom 741 of the body 74 and exposed in the extended installation space 72 through the mounting groove 7412. One end of the connection circuit board 30 is electrically connected to the main controller 4012, and the other end is electrically connected to the extended circuit board module 200 through the first electrical connector 50. The first electrical connector 50 is connected to the connection circuit board 30 and is located in the mounting groove 7412 of the bottom 741. The first electrical connector 50 is opposite to the opening 743, and the space between the opening 743 and the bottom 741 is used to accommodate the extended circuit board module 200.

[0042] The first electrical connector 50 is an interface for connecting the circuit board 30 and an external device. In this embodiment, the first electrical connector 50 is used to plug and match with the second electrical connector 40 to connect the expansion circuit board 20 and the connection circuit board 30. The first electrical connector 50 may be provided with a metal slot, and a plurality of circuit chips are arranged in the metal slot. When in use, by inserting a part of the structure of the second electrical connector 40 into the metal slot, the communication function between the expansion circuit board 20 and the connection circuit board 30 can be realized.

[0043] Please also see Figure 3 and Figure 4 In this embodiment, the control device 100 may further include a guide rail 90, which is disposed in the extended installation space 72 and connected to the body 74. The guide rail 90 is used to slidably cooperate with the extended circuit board 20 of the extended circuit board module 200, so that the extended circuit board 20 can be installed in the bracket 70 through the guide rail 90. The guide rail 90 can be fixedly connected to the inner wall of the body 74. The first electrical connector 50 and the second electrical connector 40 have a plug-in direction Y when plugged in and out. The plug-in direction Y is consistent with the extension direction of the guide rail 90, that is, the guide rail 90 is extended along the plug-in direction Y.

[0044] When installing the extended circuit board 20, the extended circuit board 20 is completely pushed into the bracket 70 along the guide rail 90 to complete the plug-in matching of the first electrical connector 50 and the second electrical connector 40. When the guide rail 90 and the extended circuit board 20 are slidably matched, the extension direction of the plane where the extended circuit board 20 is located is parallel to or coincides with the extension direction of the guide rail 90, and the extended circuit board 20 is plugged in longitudinally, which avoids the situation that the components on the extended circuit board 20 are loose or deformed when plugged in vertically. The guide rail 90 provides guidance for the installation of the extended circuit board 20, making the installation of the extended circuit board 20 convenient and accurate, and reducing the loss of the first electrical connector 50 and the second electrical connector 40.

The notches of the two guide grooves 92 of the two guide rails 90 are opposite, and the two guide grooves 92 are respectively used to accommodate the opposite sides of the expansion circuit board 20. When the expansion circuit board 20 is installed, the two sides of the expansion circuit board 20 are respectively embedded in the two guide grooves 92.

[0046] In this embodiment, the space between the first electrical connector 50 and the two guide rails 90 is arranged in parallel in the extension direction of the guide rails 90. That is, the space between the first electrical connector 50 and the two guide rails 90 is arranged in parallel in the plug-in direction Y, so that when the expansion circuit board 20 is installed, it can move along the guide rails 90 into the body 74 to get close to the first electrical connector 50, and can move to the second electrical connector 40 to be plugged and matched with the first electrical connector 50.

[0047] In some embodiments, multiple expansion circuit board modules 200 may be provided, and multiple expansion circuit board modules 200 may be detachably connected to the bracket 70. Specifically, two guide rails 90 arranged opposite to each other form a guide rail group 91, and the number of guide rail groups 91 is set to be multiple, and multiple guide rail groups 91 are arranged at intervals to respectively match multiple expansion circuit board modules 200. Multiple guide rail groups 91 are arranged at intervals along the first direction Z, and the first direction Z intersects (for example, perpendicularly) with the plug-in direction Y. In this embodiment, the first direction Z is the height direction of the bracket 70. Multiple expansion circuit board modules 200 are arranged in parallel along the first direction Z, and the types of multiple expansion circuit board modules 200 can be the same or different. As an example, the types of multiple expansion circuit board modules 200 are different. The number of first electrical connectors 50 is also multiple, and multiple first electrical connectors 50 are arranged one-to-one with multiple guide rail groups 91. The types of multiple first electrical connectors 50 are different to adapt to different types of expansion circuit board modules 200.

[0048] The control device 300 may include multiple expansion circuit board modules 200 of different types to meet different needs, and multiple expansion circuit board modules 200 can be installed on the bracket 70 through a detachable plug-in connection, which is convenient for disassembly and assembly, and further improves the adaptability of the control device 300.

Among them, the communication bus connector can adopt the Modbus protocol, and the network transmission interface can be an interface based on a network data structure (such as OPC) protocol.

[0049] In this embodiment, the extension direction of the plane where the expansion circuit board 20 is located is consistent with the plug-in direction Y, the second electrical connector 40 is connected to the end of the expansion circuit board 20 facing the first electrical connector 50, the expansion circuit board 20 slides into the bracket 70 along the guide rail 90, and the second electrical connector 40 is plugged and matched with the first electrical connector 50.

When the expansion circuit board 20 slides into the bracket 70 and the first electrical connector 50 and the second electrical connector 40 are connected, the mounting panel 80 shields at least a portion of the opening 743. The mounting panel 80 is also provided with a clearance opening for making way for the third electrical connector 60, so that the third electrical connector 60 can be electrically connected to the robot 401.

The holding fixture 110 may have a first end and a second end opposite to each other, and the holding fixture 110 is inserted into the mounting panel 80 so that the first end and the second end are respectively located on opposite sides of the mounting panel 80. The first end of the holding fixture 110 is located on a side of the mounting panel 80 away from the extended circuit board 20 and protrudes relative to the side surface to facilitate user holding.

The bracket 70 may also include a connecting portion 76, which is connected to the body 74 and is located in the opening 743, and the connecting portion 76 is used to be detachably connected to the extended circuit board module 200.

The connection portion 76 may be provided with a threaded hole, and the holding fixture 110 may be rotatably connected to the mounting panel 80, and an external thread is provided on the peripheral wall of the second end of the holding fixture 110. When the second electrical connector 40 is plugged into the first electrical connector 50, the second end of the holding fixture 110 is embedded in the connection portion 76 and threadedly connected to the connection portion 76. The holding fixture 110 provides a fulcrum for the user to install the expansion circuit board 20, and also plays a locking role to prevent the expansion circuit board 20 from retreating.

[0053] When installing the expansion circuit board 20, the user holds the holding fixture 110, inserts the two sides of the expansion circuit board 20 into the two guide grooves 92 respectively, and pushes the expansion circuit board 20 into the bracket 70 along the guide rails 90 until the second electrical connector 40 is plugged into the first electrical connector 50. At this time, the installation panel 80 covers part of the opening 743, and the second end of the holding fixture 110 is inserted into the connecting portion 76. The user tightens the holding fixture 110 so that the second end is threadedly connected to the connecting portion 76, thereby locking the expansion circuit board 20 to the bracket 70 to prevent the expansion circuit board 20 from retreating.
