[0039] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0040] In the description of the embodiments of this utility model, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of the embodiments of this utility model, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances.

[0042] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0043] like Figure 1 and Figure 2 As shown, a top plate structure according to an embodiment of the present utility model includes a first plate group 110, a second plate group 120, a first rotating component 130, and a second rotating component 140.

[0044] Specifically, the first board assembly 110 includes a first main board 111 and a second main board 112 that are movably connected. The second main board 112 is located to one side of the first main board 111 and is movable relative to the first main board 111 in a first direction X, to move away from or towards the first main board 111. When the top plate structure needs to be folded away, the second main board 112 can be moved towards the first main board 111, causing the first board assembly 110 to fold down and reduce its space occupation. Figure 2 As shown by the dashed lines, in the first direction X, the first motherboard 111 has a first region Z1 and a second region Z2, with the second region Z2 located on the side of the first region Z1 closer to the second motherboard 112. The second motherboard 112 has a third region Z3 and a fourth region Z4, with the third region Z3 located on the side of the fourth region Z4 closer to the first motherboard 111. For example, as... Figure 2 As shown, the center line of the first motherboard 111 in the first direction X is the dividing line. On the first motherboard 111, the side of its dividing line closer to the second motherboard 112 is the second region Z2, and the other side is the first region Z1. The center line of the second motherboard 112 in the first direction X is the dividing line. On the second motherboard 112, the side of its dividing line closer to the first motherboard 111 is the third region Z3, and the other side is the fourth region Z4.

[0045] The second plate group 120 is connected to one side edge of the first plate group 110, such as Figure 1 As shown, in the second direction Y, which is perpendicular to the first direction X, the second plate group 120 is located at one side edge of the first plate group 110. There can be two second plate groups 120, one located at each side edge of the first plate group 110. Figure 2As shown, the second plate assembly 120 includes a first sub-plate 121 and a second sub-plate 124. The first sub-plate 121 is rotatably connected to the first main plate 111. The first sub-plate 121 can rotate between a folded position and an unfolded position. The first sub-plate 121 has a first pivot 122 located at the connection between the first sub-plate 121 and the first main plate 111. The first sub-plate 121 rotates around the first pivot 122 between the folded position and the unfolded position. The first pivot 122 is parallel to the first direction X. When the first sub-plate 121 is in the folded position, the first sub-plate 121 and the first main plate 111 are perpendicular or approximately perpendicular to each other. When the first sub-plate 121 is in the unfolded position, the first sub-plate 121 and the first main plate 111 are parallel or approximately parallel. During the rotation of the first sub-plate 121 from the folded position to the unfolded position, the included angle between the first sub-plate 121 and the first main plate 111 gradually increases.

[0046] The second sub-plate 124 is rotatably connected to the second main plate 112. The second sub-plate 124 is located on the side of the first sub-plate 121 closest to the second main plate 112. The second sub-plate 124 can rotate between a folded position and an unfolded position. The second sub-plate 124 has a second pivot 125 located at the connection between the second sub-plate 124 and the second main plate 112. The second sub-plate 124 rotates around the second pivot 125 between the folded and unfolded positions. The second pivot 125 is parallel to the first direction X. When the second sub-plate 124 is in the folded position, the second sub-plate 124 and the second main plate 112 are perpendicular or approximately perpendicular to each other. When the second sub-plate 124 is in the unfolded position, the second sub-plate 124 and the second main plate 112 are parallel or approximately parallel. During the rotation of the second sub-plate 124 from the folded position to the unfolded position, the included angle between the second sub-plate 124 and the second main plate 112 gradually increases.

[0047] When the second main board 112 moves relative to the first main board 111, it drives the second sub-board 124 to move, allowing the second sub-board 124 to move relative to the first sub-board 121 in the first direction X. Thus, when the top panel structure needs to be folded, the second main board 112 moves toward the first main board 111, and drives the second sub-board 124 toward the first sub-board 121, thereby reducing the width of the top panel structure in the first direction X. This also causes the first sub-board 121 and the second sub-board 124 to rotate toward the folded position, reducing the angle between the first sub-board 121 and the first main board 111, and reducing the angle between the second sub-board 124 and the second main board 112, thereby reducing the width of the top panel structure in the second direction Y and improving the folding compression rate of the top panel structure.

[0048] The first rotating assembly 130 is located in the first region Z1. One end of the first rotating assembly 130 is connected to the first main board 111, and the other end is connected to the first sub-board 121. The first rotating assembly 130 can drive the first sub-board 121 to rotate around the first rotating shaft 122. The second rotating assembly 140 is located in the fourth region Z4, such that the second rotating assembly 140 is far away from the first rotating assembly 130. One end of the second rotating assembly 140 is connected to the second main board 112, and the other end is connected to the second sub-board 124. The second rotating assembly 140 can drive the second sub-board 124 to rotate around the second rotating shaft 125. In this way, during the movement of the second main board 112 and the second sub-board 124 along the first direction X, interference between the second main board 112 and the second sub-board 124 and the first rotating assembly 130 or the second rotating assembly 140 can be avoided, thereby realizing the folding and compression of the top plate structure. In some embodiments, the first rotating component 130 is disposed at the end of the first main board 111 away from the second main board 112, and the second rotating component 140 is disposed at the end of the second main board 112 away from the first main board 111, so as to maximize the reduction of the width of the top plate structure in the first direction.

[0049] According to the top plate structure of this utility model embodiment, the top plate structure is configured as a first plate group 110 and a second plate group 120 rotatably connected. The first plate group 110 includes a first main plate 111 and a second main plate 112, and the second main plate 112 is movable relative to the first main plate 111 in a first direction X. The second plate group 120 includes a first sub-plate 121 and a second sub-plate 124. The first sub-plate 121 is rotatably connected to the first main plate 111 and is rotatable between a folded position and an unfolded position; the second sub-plate 124 is rotatably connected to the second main plate 112 and is rotatable between a folded position and an unfolded position. A first rotating component 130 is disposed in a first region Z1, and a second rotating component 140 is disposed in a fourth region Z4. The second rotating component 140 and the first rotating component 130 are disposed far apart from each other to avoid interference between the first main plate 111, the second main plate 112, the first sub-plate 121, the second sub-plate 124 and the first rotating component 130 or the second rotating component 140. This allows the top plate structure to reduce its width in the first direction X by moving the first main plate 111 relative to the first main plate 111. By rotating the first sub-plate 121 and the second sub-plate 124 to the folded position, the width of the top plate structure in the direction perpendicular to the first direction X is reduced. This enables the top plate structure to deform and reduce its width in multiple directions, thereby improving the folding compression rate of the top plate structure and reducing transportation costs.

[0050] According to some embodiments of this utility model, the first rotating assembly 130 includes a first part and a second part. The first part is connected to the first main board 111, and the second part is connected to the first sub-board 121. The first part and the second part are rotatably connected, forming a first connecting fulcrum 132. When the first sub-board 121 rotates from the unfolded position to the retracted position, the first connecting fulcrum 132 moves toward the connection point between the first sub-board 121 and the first main board 111. When the first sub-board 121 rotates from the unfolded position to the retracted position, an angle is formed between the first sub-board 121 and the first main board 111, and the first connecting fulcrum 132 moves toward the connection point between the first sub-board 121 and the first main board 111, so that the first rotating assembly 130 deforms toward the angle between the first sub-board 121 and the first main board 111 for storage, saving space and preventing the first rotating assembly 130 from causing injury to the user.

[0051] The second rotating assembly 140 includes a third part and a fourth part. The third part is connected to the second main board 112, and the fourth part is connected to the second sub-board 124. The third and fourth parts are rotatably connected, forming a second connecting fulcrum 142. When the second sub-board 124 rotates from the unfolded position to the retracted position, the second connecting fulcrum 142 moves toward the connection point between the second sub-board 124 and the second main board 112. When the second sub-board 124 rotates from the unfolded position to the retracted position, an angle is formed between the second sub-board 124 and the second main board 112. The movement of the second connecting fulcrum 142 toward the connection point between the second sub-board 124 and the second main board 112 causes the second rotating assembly 140 to deform toward the angle between the second sub-board 124 and the second main board 112 for storage, saving space and preventing the second rotating assembly 140 from causing injury to the user.

[0052] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, the first part includes a first rotating rod 131, the second part includes a first rocker arm 133, and a first connecting part 123 is provided on the first sub-plate 121. The first rocker arm 133 is rotatably connected to the first connecting part 123, as shown. Figure 3 As shown, the first connecting part 123 is located on the side of the first sub-plate 121 near the second main plate 112. The first connecting part 123 is a sheet metal structure. The first rocker arm 133 is rotatably connected to the first connecting part 123 via a pivot shaft. One end of the first rotating rod 131 is connected to the first main plate 111, and the first rotating rod 131 can rotate relative to the first main plate 111. The other end of the first rotating rod 131 is rotatably connected to the first rocker arm 133, forming the first connecting fulcrum 132. The first rotating rod 131 and the first rocker arm 133 can be rotatably connected via a pivot shaft. Figure 2As shown, there can be two first rocker arms 133 and two first rotating rods 131, with the two first rocker arms 133 and the two first rotating rods 131 arranged in parallel, thereby improving the strength of the first rotating assembly 130. When the first rotating rod 131 rotates relative to the first main board 111, it drives the first rocker arms 133 to move, causing the first connecting part 123 to move away from or towards the first main board 111, so that the first sub-plate 121 rotates between the folded position and the unfolded position. During this process, the first rocker arms 133 can swing relative to the first sub-plate 121. The first rotating rod 131 and the first rocker arm 133 drive the first sub-plate 121 to rotate. The first rotating rod 131 and the first rocker arm 133 can rotate relative to each other. On the one hand, the first rotating rod 131 and the first rocker arm 133 can be folded, reducing the space occupied by the first rotating assembly 130. On the other hand, when the first sub-plate 121 rotates to the folded position, the first connecting part 123 can be as close as possible to the first main plate 111, so that the first sub-plate 121 can be perpendicular to the first main plate 111, thereby improving the folding compression rate of the top plate structure.

[0053] According to some embodiments of this utility model, the first part further includes a first base 134 and a first driving member 135. The first base 134 is fixedly connected to the first main board 111, and the first rotating rod 131 is rotatably connected to the first base 134. Figure 3 As shown, the first base 134 includes a first connecting rib 136 and a first supporting rib 137. The first connecting rib 136 is connected to the first main board 111 by fasteners. One end of the first supporting rib 137 is connected to the first connecting rib 136, and the first supporting rib 137 and the first connecting rib 136 are perpendicular to each other. The other end of the first supporting rib 137 is rotatably connected to the first rotating rod 131 through a pivot shaft.

[0054] One end of the first driving member 135 is connected to the first base 134 and spaced apart from the first rotating rod 131, while the other end is connected to the first connecting fulcrum 132, thereby driving the first rotating rod 131 to rotate relative to the first base 134. Figure 3 As shown, one end of the first driving member 135 is rotatably connected to the end of the first support rib 137 near the first connecting rib 136 via a pivot shaft, and the other end is rotatably connected to the first rotating rod 131 via a pivot shaft. In some embodiments, the first driving member 135 can be an electric push rod or a cylinder. The first driving member 135 is telescopic along its own length direction, and by extending or shortening the first driving member 135, the first connecting fulcrum 132132 is moved, thereby causing the first rotating rod 131 to rotate.

[0055] like Figure 6As shown, according to some embodiments of the present invention, when the first sub-plate 121 is in the folded position, the first rocker arm 133 is located on the side of the first connecting portion 123 near the first main plate 111, and the first rotating rod 131 is located on the side of the first base 134 near the first sub-plate 121, so that the first rotating assembly 130 folds towards the connection between the first main plate 111 and the first sub-plate 121, reducing the space occupied by the first rotating assembly 130 and preventing the user from colliding with the first rotating rod 131 or the first rocker arm 133. When the first sub-plate 121 rotates from the folded position to the unfolded position, the first rotating rod 131 rotates towards the side of the first base 134 away from the first sub-plate 121.

[0056] like Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, the third part includes a second rotating rod 141, the fourth part includes a second rocker arm 143, and a second connecting part 126 is provided on the second sub-plate 124. The second rocker arm 143 is rotatably connected to the second connecting part 126. The second connecting part 126 can be provided on the side of the second sub-plate 124 opposite to the first sub-plate 121. The second connecting part 126 is a sheet metal structure to improve the connection strength. The second connecting part 126 and the second rocker arm 143 can be rotatably connected via a pivot shaft.

[0057] One end of the second rotating rod 141 is connected to the second main board 112, and the second rotating rod 141 is rotatable relative to the second main board 112. For example, the second rotating rod 141 and the second main board 112 can be connected by a hinge. The other end of the second rotating rod 141 is rotatably connected to the second rocker arm 143, forming the second connection fulcrum 142. The second rotating rod 141 and the second rocker arm 143 can be rotatably connected by a pivot. When the second rotating rod 141 rotates relative to the second main board 112, the second rotating rod 141 drives the second rocker arm 143 to move, thereby causing the second connecting part 126 to move away from or towards the second main board 112, thus causing the second sub-plate 124 to rotate between the folded position and the unfolded position. During this process, the second rocker arm 143 can swing relative to the second sub-plate 124. The second sub-plate 124 is driven to rotate by the second rotating rod 141 and the second rocker arm 143. The second rotating rod 141 and the second rocker arm 143 can rotate relative to each other. On the one hand, the second rotating rod 141 and the second rocker arm 143 can be folded to reduce the space occupied by the second rotating assembly 140. On the other hand, when the second sub-plate 124 rotates to the folded position, the second connecting part 126 can be as close as possible to the second main plate 112. The second sub-plate 124 can be perpendicular to the second main plate 112, thereby improving the folding compression rate of the top plate structure.

[0058] According to some embodiments of this utility model, the third part further includes a second base 144 and a second driving member 145. The second base 144 is fixedly connected to the second main board 112, and the second rotating rod 141 is rotatably connected to the second base 144. Figure 4 As shown, the second base 144 includes a second connecting rib 146 and a second supporting rib 147. The second connecting rib 146 is connected to the second main board 112 by fasteners. One end of the second supporting rib 147 is connected to the second connecting rib 146, and the second supporting rib 147 and the second connecting rib 146 are perpendicular to each other. The other end of the second supporting rib 147 is rotatably connected to the second rotating rod 141 through a pivot shaft.

[0059] One end of the second driving member 145 is connected to the second base 144 and spaced apart from the second rotating rod 141, while the other end of the second driving member 145 is connected to the second connecting fulcrum 142 to drive the second rotating rod 141 to rotate relative to the second base 144. Figure 3 As shown, one end of the second support rib 147 near the second connecting rib 146 is rotatably connected to one end of the second driving member 145 via a pivot shaft, and the other end is rotatably connected to the second rotating rod 141 via a pivot shaft. In some embodiments, the second driving member 145 can be an electric push rod or a cylinder push rod. The second driving member 145 is telescopic along its own length direction, and the extension or shortening of the second driving member 145 drives the second connecting fulcrum 142142 to move, thereby causing the second rotating rod 141 to rotate.

[0060] like Figure 7 As shown, according to some embodiments of the present invention, when the second sub-plate 124 is in the folded position, the second rocker arm 143 is located on the side of the second connecting portion 126 near the second main plate 112, and the second rotating rod 141 is located on the side of the second base 144 near the second sub-plate 124, so that the second rotating assembly 140 folds towards the connection between the second main plate 112 and the second sub-plate 124, reducing the space occupied by the second rotating assembly 140 and preventing the user from colliding with the second rotating rod 141 or the second rocker arm 143. When the second sub-plate 124 rotates from the folded position to the unfolded position, the second rotating rod 141 rotates towards the side of the second base 144 away from the second sub-plate 124.

[0061] According to some embodiments of this utility model, the top plate structure further includes a reinforcing rod 150. The reinforcing rod 150 is disposed on the side of the second main plate 112 opposite to the first main plate 111, and is located at the end of the second main plate 112 closest to the first main plate 111. The reinforcing rod 150 is telescopic along its own length. When the reinforcing rod 150 is in the retracted state, the telescopic end 151 of the reinforcing rod 150 is located on the second main plate 112, avoiding interference between the reinforcing rod 150 and the first sub-plate 121. Figure 2 and Figure 5As shown, when the reinforcing rod 150 is in the extended state, and both the first sub-plate 121 and the second sub-plate 124 are in the unfolded position, the telescopic end 151 of the reinforcing rod 150 abuts against the second sub-plate 124 to support the second sub-plate 124 and the first sub-plate 121, thereby improving the stability of the top plate structure.

[0062] A mobile building according to this utility model includes a main body and a top plate structure as described above. A first plate assembly 110 is connected to the main body, and the top plate structure is located on top of the main body. Specifically, the main body includes a base plate and walls. The base plate, walls, and top plate structure enclose the internal space of the mobile building. Support columns are provided on the base plate, and the first plate assembly 110 is connected to the support columns.

[0063] In summary, this utility model embodiment provides a top plate structure that reduces the width of the top plate structure in multiple directions by moving the first main plate 111 relative to the first main plate 111 in a first direction X, and by rotating the first sub-plate 121 and the second sub-plate 124 to a folded position, thereby increasing the folding compression rate of the top plate structure and reducing transportation costs. The first rotating rod 131 and the first rocker arm 133 drive the first sub-plate 121 to rotate, and the second rotating rod 141 and the second rocker arm 143 drive the second sub-plate 124 to rotate, enabling the first rotating assembly 130 and the second rotating assembly 140 to fold. When the top plate structure is folded, the space occupied by the first rotating assembly 130 and the second rotating assembly 140 is smaller, and the folding compression rate of the top plate structure is higher.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit it. It should be pointed out that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
