Referring to fig. 4 and fig. 6, after the power interface 123 takes power, the voltage is reduced through a terminal strip, and the 220V ac power is converted into 48V dc power, which is then provided to the main control board 121 and each sub-controller 130. Each mounting groove 110a is correspondingly provided with a plug-in bottom plate 140, the power interface 123 is connected to the main control board 121, the main control board 121 is connected to the plug-in bottom plate 140, and the sub-controller 130 is detachably connected to the plug-in bottom plate 140. The socket base plate 140 may be provided with a power connector (not shown), an adaptor (not shown), and a data interface 141, and is connected to the terminal strip through the power connector, and is connected to the main control board 121 through the adaptor, the sub-controller 130 is connected to the data interface 141, and is connected to the main control board 121 through the data interface 141, the main control board 121 distributes data to each data interface 141, and the sub-controller 130 obtains the data through the data interface 141, thereby performing a screen loading operation. The sub-controller 130 and the data interface 141 are detachably fixed: when the sub-controller 130 is assembled and fixed in the installation groove 110a, the sub-controller and the plug base plate 140 are mutually plugged and fixed through the data interface 141, and meanwhile, the data connection is established with the plug base plate 140 through the data interface 141; when the sub-controller 140 is pulled out, the sub-controller 140 is separated from the data interface 141, and the sub-controller 130 is disconnected from the main control board 121.

Specifically, in the embodiment shown in fig. 4, each parallel space is divided into two mounting grooves 110a, and the two mounting grooves 110a share one plugging base plate 140, so that the two mounting grooves 110a can share part of the circuits on the plugging base plate 140, and meanwhile, the plugging base plate 140 can have a larger area, which is beneficial to the circuit design on the plugging base plate 140 and the fixation of the plugging base plate 140 itself.

In particular embodiments, sub-controllers 130 are hot-plugged into docking cradle 140 such that video controller array 10 can add or remove sub-controllers 130 during use. For example, the sub-controller 130 implements hot plugging with the plug backplane 140 via the data interface 141. From this, when the area that the LED display screen corresponds appears the demonstration problems such as black screen in the area of carrying, can directly demolish sub-controller 130 that the area of carrying problem was regional, change new sub-controller 130, and need not to overhaul at the scene, only need overhaul the sub-controller 130 of demolising can, can not influence the demonstration of LED display screen for the LED display screen can resume normal demonstration in short time.

The blocking portion 1351 and the pushing portion 1353 with a predetermined included angle can enhance the clamping between the protruding buckle 135 and the case 110, and prevent the protruding buckle 135 from slipping off the case 110.

A wedge-shaped surface 1355 may be disposed on the protruding buckle 135, the wedge-shaped surface 1355 is used for providing a buffer when the sub-controller 130 slides into the mounting groove 110a, when the sub-controller 130 slides in, the chassis 110 slides along the wedge-shaped surface 1355 of the protruding buckle 135, the free end 1333 of the buckle 133 is pressed down, and finally the protruding buckle 135 is completely retracted into the through hole 1311, and after the sliding is in place, the buckle 133 is automatically reset, and the sub-controller 130 is automatically clamped with the chassis 110. In the illustrated embodiment, the wedge 1355 is disposed on the relief portion 1353.

According to the video controller array 10, by arranging the plurality of sub-controllers 130, each sub-controller 130 can carry the LED display screen, and data connection is established between the plurality of sub-controllers 130 and the main control module 120, so that the plurality of sub-controllers 130 can cooperate to complete the picture carrying that the required carrying capacity exceeds the carrying capacity of a single sub-controller 130 under the coordination of the main control module 120. The sub-controllers 130 are detachably connected to the chassis 110, and are connected to or disconnected from the main control module 120 during the installation and disassembly processes, so that different loading capacities can be realized by changing the number of the sub-controllers 130, and the dynamic adjustment of the loading capacity of the video controller array 10 can be realized, thereby adapting to scenes without loading capacities.

Further, sub-controller 130 is capable of implementing hot-plugging, so that sub-controller 130 can be replaced or added in a timely manner. The fastening member 133 is disposed to keep the sub-controller 130 and the case 110 clamped, so as to prevent the sub-controller 130 from being disconnected easily and causing power failure.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
