DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] Reference Figure 1-5 A folding display board includes a device body 1, the device body 1 includes a mounting base 2, the mounting base 2 is provided with a display board structure 3, the display board structure 3 includes a supporting component 4, the supporting component 4 is provided with a display board component 5, the display board component 5 includes a No. 1 fixed plate 501, the No. 1 fixed plate 501 is provided with four expansion components 502, and the expansion component 502 is composed of two expansion components 502.

[0028] The mounting base 2 includes a base 201, and a cylinder No. 1 202 is fixedly connected inside the base 201. The cylinder No. 1 202 is a prior art and will not be described in detail here. The output end of the cylinder No. 1 202 is fixedly connected to a bottom plate 203, and the length and width of the bottom plate 203 are the same as the length and width of the inside of the base 201. When the bottom plate 203 is retracted into the base 201, the top of the base 201 exceeds a part of the top of the bottom plate 203.

[0029] The supporting component 4 includes a No. 2 cylinder 401 fixedly connected to the base plate 203. The No. 2 cylinder 401 is a prior art and will not be elaborated on here. The output end of the No. 2 cylinder 401 is fixedly connected to the mounting plate 402. Support assemblies 403 are provided on both sides of the mounting plate 402. The supporting assembly 403 includes a rotating drum 4034 hinged to the base plate 203. An extension plate 4032 is slidably connected inside the rotating drum 4034, and the other end of the extension plate 4032 is hinged to the No. 1 fixed plate 501.

[0030] The first fixing plate 501 is hinged to the mounting plate 402 , and each of the four sides of the first fixing plate 501 corresponds to a second fixing plate 503 and is hinged to the second fixing plate 503 .

[0031] The expansion component 502 includes a No. 2 fixed plate 5021, and a magnet 5022 is provided on one side of the No. 2 fixed plate 5021. The magnetic fields of the magnets 5022 in the same group of expansion components 502 are opposite, and suction will be generated between the two. A slide plate 5023 is slidably connected to one side of the No. 2 fixed plate 5021, and the slide plate 5023 is made of magnetic metal material. A groove 5042 is provided on the other side of the No. 2 fixed plate 5021. The adjacent expansion components 502 are connected at the ends, and the groove 5024 corresponds to the slide plate 5023. A damping rubber is provided in the groove 5024, and the damping rubber is not shown in the figure.

[0032] When folding, take out the magnet, stick it on the No. 2 fixing plate 5021, and align it with the groove 5024, then move the magnet to another No. 2 fixing plate 5021, then the slide plate 5023 will move back until it is completely moved out of the groove 5024, then rotate the corresponding No. 2 fixing plate 5021 to make the two No. 2 fixing plates 503 fit together, then under the action of the suction force between the two magnets 5022, the two No. 2 fixing plates 5021 will be fixed together, and so on, the other expansion components 502 can be folded.

[0033] Then, the output end of the No. 2 cylinder 401 is controlled to move downward with the mounting plate 402. At this time, the height of the No. 1 fixed plate 501 will be reduced, and when the position of the No. 1 fixed plate 5021 changes, one end of the extension plate 5032 will change accordingly, so that the support component 403 will pull it down. At this time, the No. 1 fixed plate 501 will rotate until it overlaps with the mounting plate 402. In this process, the No. 2 fixed plate 5021 hinged to the side of the No. 1 fixed plate 501 will also rotate until it is perpendicular to the No. 1 fixed plate 501, and one side of the No. 1 fixed plate 501 will contact the top of the bottom plate 203.

[0034] Finally, the output of cylinder No. 1 202 is controlled to move the bottom plate 203 downward. When the bottom plate 203 moves downward, the fixed plate No. 2 5021 will also move along until the bottom plate 203 moves into the base 201, and a part of the fixed plate No. 2 5021 will also move into the base 201, and the side surface of the fixed plate No. 2 5021 will be connected to the inner side of the base 201, thereby fixing and limiting the fixed plate No. 2 5021.
