[0061] Please refer to Figure 1 refer to Figure 4 , a flap device provided in the embodiments of the present application includes: a support structure 10, a flipping member 20 and two pressing components 30.

[0062] The support structure 10 serves as the support main body of the flap device, and is used to support other components and allow the sheet 40 to be placed for flipping. The support structure 10 can be in the shape of a bracket; in this embodiment, the support structure 10 is a square column-shaped bracket with a hollow interior for the sheet 40 to be flipped.

[0063] In this embodiment, the flipping member 20 serves as the component that drives the sheet 40 to flip, and is rotatably arranged on the support structure 10. In practical applications, a bearing seat 15 can be arranged on the support structure 10; please refer to Figure 4 , a rotating shaft 22 can be connected to the flipping member 20, and the flipping member 20 is rotatably installed on the bearing seat 15 through the rotating shaft 22. Correspondingly, a power component 16 can be provided to drive the rotation of the rotating shaft 22, thereby driving the flipping of the flipping member 20; the power component 16 can include a motor and transmission equipment, which will not be elaborated in this solution. And, a power control component 14 for controlling the power component 16 can be arranged on the support structure 10.

[0064] In this embodiment, a through cavity 21 for placing the plate 40 is provided on the flipping member 20; the through cavity 21 penetrates the flipping member 20 along the normal direction of the plate 40. It should be noted that in this embodiment, the normal direction of the plate 40 refers to the normal direction when the plate 40 is placed in the through cavity 21, that is, the direction perpendicular to the plane of the plate 40, and at the same time, it is also in the Figure 1 x-axis direction shown in

[0065] Two pressing components 30 are respectively arranged on both sides of the flipping member 20 along the normal direction of the plate 40, that is, on both sides of the communication direction of the through cavity 21. The two pressing components 30 are used to press both sides of the plate 40 respectively when the plate 40 needs to be flipped.

[0066] When the plate 40 needs to be taken and placed, the pressing component 30 can move away from the flipping member 20 so that the plate 40 can be taken out of or placed into the through cavity 21. Among them, the way that the pressing component 30 moves away from the flipping member 20 can be, for example, that the pressing component 30 is detachably connected to the flipping member 20, so that when the plate 40 needs to be taken and placed, the pressing component 30 can be disassembled. The way that the pressing component 30 moves away from the flipping member 20 can also be, for example, that the pressing component 30 is flip-connectable to the flipping member 20. Correspondingly, when the plate 40 needs to be taken and placed, the pressing component 30 is flipped to open the through cavity 21. The way that the pressing component 30 moves away from the flipping member 20 can also be, for example, slidable connection, that is, the pressing component 30 is slidably connected to the flipping member 20 along the normal direction of the plate 40.

[0067] At the same time, in practical applications, the two pressing components 30 can adopt different connection methods; for example, one pressing component 30 is flip-connected to one side of the flipping member 20, and the other pressing component 30 is detachably connected to the other side of the flipping member 20.

[0068] In this solution, after the plate 40 is placed in the through cavity 21, the two pressing components 30 can press the plate 40 against the flipping member 20 from both sides respectively, and then the power component 16 drives the flipping member 20 to rotate around the rotation axis 22 to realize the flipping of the plate 40. In this embodiment, the rotation axis 22 can be set at the central position of the flipping member 20, so that the plate 40 can be flipped around itself, and thus the occupied area of the support structure 10 can be reduced.

[0069] Compared with the hoisting and flipping method, this solution can reduce the occupied area, reduce the complexity of fixing the plate 40, reduce the possibility of the plate 40 falling, and improve the simplicity of operation.

[0070] In a further improved embodiment, please refer to Figure 3 and Figure 5, the pressing assembly 30 includes: a connecting member 31 and a plurality of first pressing members 32; the connecting member 31 is used to connect the flipping member 20; the first pressing member 32 is movably disposed on the connecting member 31 along a first direction, and is used to press and fix the sheet 40 in the through cavity 21 when the sheet 40 needs to be flipped.

[0071] In this embodiment, the first direction may be the same as the normal direction after the above-mentioned sheet 40 is placed in the through cavity 21, that is, the first direction is also the Figure 1 x-axis direction in

[0072] At the same time, in this embodiment, the first pressing member 32 may include a plurality of them, so as to be able to provide a pressing force to the normal plane of the sheet 40 from multiple different positions, and achieve better pressing of the sheet 40.

In this embodiment, by rotating the first screw 34, the first pressing member 32 is driven to slide along the first direction, so as to control the first pressing member 32 to press the sheet 40 or move away from the sheet 40.

[0076] In a more specific embodiment, a guiding groove 35 is provided on the connecting member 31; the first pressing member 32 is slidably disposed in the guiding groove 35 along the first direction. The guiding groove 35 can play a guiding role for the sliding of the first pressing member 32.

[0080] In this embodiment, the first direction in which the first pressing member 32 slides corresponds to the normal plane of the plate 40; the second direction in which the second pressing member 33 slides corresponds to the side surface of the plate 40; thus, the normal plane and the side surface of the plate 40 can be simultaneously pressed by the first pressing member 32 and the second pressing member 33, so as to better fix the plate 40.

[0081] Wherein, there may be a plurality of second pressing members 33, which are respectively disposed on two sides or multiple sides of the connecting member 31.

[0086] As an improved manner, the pushing member 37 fixedly connects to multiple regions of the second pressing member 33 through a plurality of extension rods 39, and can provide a thrust force for the second pressing member 33 from multiple regions, so that the second pressing member 33 can better press the side of the plate 40. Correspondingly, the second pressing member 33 may be a long strip-shaped plate body corresponding to the shape of the side surface of the plate 40.

[0087] In one embodiment, the connecting member 31 is detachably connected to the flipping member 20 and / or the connecting member 31 is flip-ably connected to the flipping member 20.

[0088] Specifically, in this embodiment, the connecting member 31 can be connected to the flipping member 20 in a detachable connection manner. For example, both sides of the connecting member 31 are connected to the flipping member 20 through detachable members such as bolts.
