[0031] Embodiment 1
[0032] As Figures 1 to 7 shown in the figure, an embodiment of the present application provides a carrier holding device, including a plug-in box 100 and a main control unit 200. The plug-in box 100 is provided with a first interface component, a second interface component and N plug-in positions 110. The first interface component is used for plugging with the second interface component. Each plug-in position 110 is provided with a plug-in port 111, and the plug-in port 111 is used for plugging with an external device. The main control unit 200 is provided with a first interface component.
[0033] In implementation, the carrier holding device provided by the present application is composed of the main control unit 200 and the plug-in box 100. There can be one or more plug-in boxes 100. The first interface components are provided on both the plug-in box 100 and the main control unit 200. The second interface component is also provided on the plug-in box 100. The first interface component and the second interface component are cooperatively plugged. That is to say, the main control unit 200 can be plugged with the plug-in box 100 through the cooperation of the first interface component and the second interface component to realize the connection between the main control unit 200 and the plug-in box 100. Similarly, the two plug-in boxes 100 can also be plugged with each other through the cooperation of the first interface component and the second interface component to realize the connection between the two plug-in boxes 100.
[0034] In implementation, each plug-in box 100 can be assembled, connected and disassembled with an external device. Among them, N plug-in positions 110 are provided on the plug-in box 100, and the plug-in port 111 of each plug-in position 110 is correspondingly plugged with an external device. That is to say, each plug-in box 100 can be plugged with N external devices. N can be a natural number greater than or equal to 1. For example, N can be 2, 3, 4, 5, 6, 8, 10 or other values, and can be specifically set according to the actual situation or usage requirements.
[0035] In some embodiments, the first interface component includes a first power supply interface 121 and a first data interface 131, and the second interface component includes a second power supply interface 122 and a second data interface 132. The first power supply interface 121 is used for connecting with the second power supply interface 122, and the first data interface 131 is used for connecting with the second data interface 132. In implementation, when the first interface component and the second interface component are correspondingly plugged, for example, when the first interface component of the first plug-in box 100 is plugged with the second interface component of the second plug-in box 100, or when the second interface component of a plug-in box 100 is plugged with the first interface component of the main control unit 200, the first power supply interface 121 is connected with the second power supply interface 122 to realize power supply connection, and the first data interface 131 is connected with the second data interface 132 to realize data transmission connection.
[0036] The plug-in port 111 of the plug-in box 100 is connected to an external device. That is to say, the main control machine 200 is connected to N external devices through the plug-in box 100, including power supply connection and data transmission connection, so as to control the working states of the respective external devices by the main control machine 200.
[0037] In some possible embodiments, the load holding device provided in the present application further includes a slave control machine 300. The slave control machine 300 is provided with a first interface component. That is to say, similar to the main control machine 200, the slave control machine 300 can be plugged into the plug-in box 100 through the first interface component and the second interface component to achieve the power supply connection and data transmission connection between the slave control machine 300 and the plug-in box 100. During implementation, the slave control machine 300 is further provided with a first communication interface, and the main control machine 200 is provided with a second communication interface. The second communication interface is used to dock with the first communication interface to achieve data transmission. That is to say, the main control machine 200 can be data-connected to the slave control machine 300. While the main control machine 200 is connected to the plug-in box 100 itself, the main control machine 200 can also be connected to the plug-in box 100 through the slave control machine 300, and then connected to the external device.
[0038] During implementation, taking that one main control machine 200 can be connected to several plug-in boxes 100 and each plug-in box 100 can be connected to two external devices as an example, when the main control machine 200 is connected to one plug-in box 100, at this time one main control machine 200 can be connected to at most two external devices, that is, one-to-two; when the main control machine 200 is connected to two plug-in boxes 100, at this time one main control machine 200 can be connected to at most four external devices, that is, one-to-four; when the main control machine 200 is connected to three plug-in boxes 100, at this time one main control machine 200 can be connected to at most six external devices, that is, one-to-six; and so on. One main control machine 200 can be one-to-N, where N is a multiple of 2, such as one-to-ten, one-to-fourteen or one-to-twenty, etc., without limitation.
[0039] In some other embodiments, the plug-in box 100 includes two modes. The first mode is that a single plug-in box 100 can be connected to two external devices, and the second mode is that a single plug-in box 100 can be connected to four external devices. The plug-in boxes 100 of the two modes can be randomly combined according to actual usage requirements. Exemplarily, when the main controller 200 needs to be connected to four external devices, that is, one-to-four, the main controller 200 can be connected to two plug-in boxes 100 of the first mode, or one main controller 200 can be connected to one plug-in box 100 of the second mode; when the main controller 200 needs to be connected to six external devices, that is, one-to-six, the main controller 200 can be connected to three plug-in boxes 100 of the first mode, or one main controller 200 can be connected to one plug-in box 100 of the first mode plus one plug-in box 100 of the second mode; when the main controller 200 needs to be connected to eight external devices, that is, one-to-eight, the main controller 200 can be connected to four plug-in boxes 100 of the first mode, or one main controller 200 can be connected to two plug-in boxes 100 of the first mode plus one plug-in box 100 of the second mode; or one main controller 200 can be connected to two plug-in boxes 100 of the second mode, and so on, which will not be elaborated here.
[0040] When the number of external devices connected to a main controller 200 exceeds a certain number, such as one-to-ten, one-to-twelve, or one-to-eighteen or more, a slave controller 300 needs to be added. The main controller 200 is connected to a part of the external devices, and then the slave controller 300 is connected to a part of the external devices, and then the main controller 200 and the slave controller 300 are connected. For example, the main controller 200 and the slave controller 300 are connected by a data cable or a network cable to supply power to and control each external device. Of course, it can also be designed to be wirelessly connected between the main controller 200 and the slave controller 300, which is not limited.
[0041] In some alternative embodiments, each plug-in position 110 is provided with a tray 112 for carrying an external device. When forming an external device, the external device can be placed on the tray 112 and then connected to the plug-in port 111.
[0042] The load holding device of the present application includes a plug-in box 100 and a main control unit 200. Among them, the plug-in box 100 is provided with a first interface component, a second interface component, and N plug-in positions 110. The first interface component is used to plug into the second interface component. Each plug-in position 110 is provided with a plug-in port 111, and the plug-in port 111 is used to plug into an external device. The main control unit 200 is provided with a first interface component. By modularizing the plug-in box 100 and the main control unit 200, the first interface component of any one plug-in box 100 can be plugged into the second interface component of another plug-in box 100, and the first interface component on the main control unit 200 can also be plugged into the second interface component of the plug-in box 100. At the same time, each plug-in box 100 can be plugged with N external devices, which facilitates the assembly and disassembly between the plug-in box 100 and the plug-in box 100, as well as between the plug-in box 100 and the external device, and reduces the difficulty of product installation, transportation, and maintenance.
[0043] In some alternative embodiments, the plug-in box 100 further includes a first latch assembly 140 and a second latch assembly 150. There are a first state of latch connection and a second state of separation between the first latch assembly 140 and the second latch assembly 150. The main control unit 200 is provided with the first latch assembly 140.
[0044] During assembly, when the first latch assembly 140 and the second latch assembly 150 are in the first state, the first latch assembly 140 and the second latch assembly 150 are latched together, that is, the first latch assembly 140 and the second latch assembly 150 are connected together to connect the two devices together; when the first latch assembly 140 and the second latch assembly 150 are in the second state, the first latch assembly 140 and the second latch assembly 150 can be separated to disassemble the two devices.
[0045] Exemplarily, the first latch assembly 140 of the main control unit 200 and the second latch assembly 150 of the plug-in box 100 are latched together, so that the main control unit 200 and the plug-in box 100 can be assembled together, and the power supply connection and data transmission connection between the main control unit 200 and the plug-in box 100 are realized by plugging the second interface component of the plug-in box 100 into the first interface component of the main control unit 200. Similarly, the first latch assembly 140 of the first plug-in box 100 can be latched with the second latch assembly 150 of the second plug-in box 100, so that the two plug-in boxes 100 can be assembled together, and the power supply connection and data transmission connection between the two plug-in boxes 100 are realized by plugging the second interface component of one of the two plug-in boxes 100 into the first interface component of the other plug-in box 100.
[0046] In some alternative embodiments, the first latching component 140 includes a first locking tooth 141 and a locking control 142, and the second latching component 150 includes a second locking tooth 151. The second locking tooth 151 is mounted on the plug-in box 100. The locking control 142 is connected to the first locking tooth 141 and is configured to drive the first locking tooth 141 to overlap or be misaligned with the second locking tooth 151.
[0047] During implementation, when the first latching component 140 is disposed on the plug-in box 100, the first locking tooth 141 is movably connected to the plug-in box 100. When the first latching component 140 is disposed on the main control unit 200, the first locking tooth 141 is movably connected to the main control unit 200. The locking control 142 is provided for a user to operate to drive the first locking tooth 141 to move, thereby achieving the overlap or misalignment of the first locking tooth 141 and the second locking tooth 151.
[0048] Exemplarily, taking the plug-in box 100 placed horizontally as an example, the plug-in boxes 100 are distributed vertically, or the plug-in box 100 and the main control unit 200 are distributed vertically. The first interface component is disposed at the bottom of the plug-in box 100 and the main control unit 200, and the second interface component is disposed at the top of the plug-in box 100. Of course, the first interface component and the second interface component may also adopt other arrangement manners. For example, the first interface component is disposed on the left side surface of the plug-in box 100 and the main control unit 200, and the second interface component is disposed on the right side surface of the plug-in box 100, which is not limited.
[0049] Taking the first interface component and the second interface component being respectively disposed at the bottom and the top of the plug-in box 100 as an example, the overlap of the first locking tooth 141 and the second locking tooth 151 means that at least a part of the projections of the first locking tooth 141 and the second locking tooth 151 on the horizontal plane overlap. At this time, the first locking tooth 141 and the second locking tooth 151 are mutually limited and cannot move freely in the vertical direction, thereby connecting two plug-in boxes 100 together, or connecting the plug-in box 100 and the main control unit 200 together; while the misalignment of the first locking tooth 141 and the second locking tooth 151 means that the projections of the first locking tooth 141 and the second locking tooth 151 on the horizontal plane are misaligned with each other. At this time, the first locking tooth 141 and the second locking tooth 151 can move freely in the vertical direction, thereby splitting two plug-in boxes 100, or splitting the plug-in box 100 and the main control unit 200.
[0050] In some alternative embodiments, the first latching component 140 further includes a first latching seat 143. The first locking tooth 141 is movably connected to the first latching seat 143. The second latching component 150 further includes a second latching seat 152. The second latching seat 152 is disposed on the plug-in box 100. The second locking tooth 151 is disposed on the second latching seat 152. The first latching seat 143 has a socket hole 144 for the second latching seat 152 to pass through.
[0051] During implementation, the second latch seat 152 is disposed on the outer shell of the plug-in box 100. For example, the second latch seat 152 is disposed on the top of the outer shell of the plug-in box 100, and the first latch seat 143 is disposed on the bottom of the outer shell of the plug-in box 100, or the first latch seat 143 is disposed on the bottom of the outer shell of the main control unit 200. The first latch seat 143 is provided with a socket hole 144, and the second latch seat 152 can be inserted into the socket hole 144 so that the positions of the first latch tooth 141 and the second latch tooth 151 correspond. For example, when the main control unit 200 is located above the plug-in box 100, the second latch tooth 151 of the main control unit 200 is located below the first latch tooth 141 of the plug-in box 100. The position of the second latch tooth 151 is adjusted by the locking control member 142 so that the first latch tooth 141 and the second latch tooth 151 overlap or are misaligned vertically.
[0052] In some alternative embodiments, the first latch seat 143 is provided with a mounting hole 145 that cooperates with the locking control member 142. The mounting hole 145 is provided with a guiding groove 146, and the locking control member 142 is provided with a guiding post 147 that cooperates with the guiding groove 146. The locking control member 142 and the first latch tooth 141 are rotatably connected.
[0053] The mounting hole 145 can be regarded as a circular hole provided in the first latch seat 143. The locking control member 142 is disposed in the circular hole. The guiding groove 146 extends along the circumferential direction of the circular hole. The locking control member 142 is provided with a guiding post 147, and the guiding post 147 is embedded in the guiding groove 146. When the locking control member 142 is rotated, under the cooperation of the guiding groove 146 and the guiding post 147, the guiding post 147 can extend into or out of the mounting hole 145. Since the locking control member 142 and the first latch tooth 141 are rotatably connected, when the locking control member 142 rotates, it will not drive the first latch tooth 141 to rotate. At the same time, when the guiding post 147 extends into or out of the mounting hole 145, it can drive the first latch tooth 141 to slide.
[0054] In some embodiments, the slave control unit 300 is also provided with a first locking assembly 140, which will not be elaborated here.
[0055] In some embodiments, the locking control member 142 is provided with an adjustment groove 148 for cooperating with an adjustment tool (not shown in the figure) to adjust the locking control member 142. During implementation, one end of the locking control member 142 is for manual operation by the user so that the guiding post 147 rotates to drive the first latch tooth 141 to slide. For better adjustment, the adjustment groove 148 is a groove provided in the locking control member 142. The adjustment tool can be a screwdriver or the like, which can be inserted into the adjustment groove 148 to operate the guiding post 147 to rotate, and the adjustment is more convenient.
