Description

Technical Field

[0001] This utility model relates to the field of mobile building technology, and in particular to a roof panel assembly and a mobile building. Background Technology

[0002] Mobile homes, RVs, and other mobile structures, as an important branch of modern construction technology, are rapidly developing due to their flexibility, sustainability, and adaptability. Mobile structures reduce their volume through collapse and folding for easy transport. The roof of a mobile structure is typically composed of multiple interconnected panels, which collapse or expand by moving and rotating relative to each other. Some panels can move relative to each other to fold or stretch, and can also flip relative to fixed components to open or close. Because the roof panels typically have few support points to allow for multi-directional movement, and the rotation of multiple panels is not along the same axis, the gaps between the panels change during rotation. Furthermore, due to gravity, misalignment can easily occur between the panels, leading to mutual compression and deformation. Utility Model Content

[0003] The technical problem to be solved by this utility model is that in related technologies, during the rotation of the roof panel of a mobile building to retract or expand, the panels that make up the roof panel are prone to misalignment and interference, resulting in mutual compression and deformation between the panels.

[0004] To solve the above-mentioned technical problems, this utility model provides a top plate assembly, comprising:

[0005] A first plate has a first axis of rotation and is capable of rotating around the first axis of rotation between a folded position and an unfolded position. A storage area is formed on the side of the first plate facing the second plate.

[0006] The second plate is located on one side of the first plate and is at least partially located within the storage area. The second plate has a second axis of rotation and is capable of rotating about the second axis of rotation between a folded position and an unfolded position. The second axis of rotation is not coaxial with the first axis of rotation.

[0007] A support member is disposed on the first plate and contacts the second plate, thereby separating the first plate from the second plate.

[0008] The second plate is provided with a storage slot, the storage slot having an opening facing the first plate; and...

[0009] The rotation of the second plate and the first plate allows the support member to slide along the second plate into or out of the storage slot.

[0010] According to one embodiment of the present invention, the second plate is movable relative to the first plate to move into or away from the storage area, and the movement of the second plate relative to the first plate can move the support member to the location of the storage slot.

[0011] According to one embodiment of the present invention, a transition slope is formed on the peripheral wall of the storage groove, the transition slope extends obliquely from the opening of the storage groove to the bottom of the storage groove, and the support member can slide into or out of the storage groove along the transition slope.

[0012] According to one embodiment of the present invention, the storage groove is located at one end of the second plate away from the second rotation axis, and the support member is located at one end of the first plate away from the first rotation axis.

[0013] According to one embodiment of the present invention, the support member includes a mounting base and a rolling element. The mounting base is connected to the first plate body, and the rolling element is rotatably connected to the mounting base. The rolling element protrudes from the side of the first plate body facing the second plate body and contacts the second plate body.

[0014] According to one embodiment of the present invention, the support member further includes a reinforcing plate, the reinforcing plate being fixedly connected to the first plate body, and the mounting base being connected to the reinforcing plate.

[0015] According to one embodiment of the present invention, the first plate includes a support frame and a cover plate, the cover plate being connected to the support frame, and the reinforcing plate being connected to the support frame.

[0016] This utility model also provides a mobile building, including:

[0017] main body;

[0018] A fixed top plate is connected to the main body and located on top of the main body;

[0019] At least one top plate assembly as described above, wherein both the first plate and the second plate are rotatably connected to the fixed top plate.

[0020] According to one embodiment of the present invention, the fixed top plate includes a first fixed plate and a second fixed plate connected to each other;

[0021] The first plate is rotatably connected to the first fixed plate, and the first rotation axis is located on the first fixed plate; the second plate is rotatably connected to the second fixed plate, and the second rotation axis is located on the second fixed plate.

[0022] The second fixing plate is movable relative to the first fixing plate, so as to move the second fixing plate into or away from the storage area.

[0023] According to one embodiment of the present invention, the mobile building has a folded state and an unfolded state.

[0024] When the mobile building is in the retracted state, the orthographic projection of the second fixing plate on the plane where the first fixing plate is located falls within the first fixing plate. Both the first plate and the second plate are in the retracted position, and the second plate is stored in the storage area.

[0025] When the mobile building is in the unfolded state, at least a portion of the orthographic projection of the second fixing plate onto the plane where the first fixing plate is located falls outside the first fixing plate. Both the first plate and the second plate are in the unfolded position, and at least a portion of the second plate is located outside the storage area.

[0026] Compared with the prior art, the advantages of the top plate assembly of this utility model embodiment are as follows:

[0027] The top plate assembly of this utility model provides support by placing a support member between the first plate and the second plate, with the support member in contact with the second plate. This separation of the first and second plates prevents them from being squeezed or deformed due to differences in rotational speed or gravity, thus extending the service life of the top plate assembly. Furthermore, when the first and second plates rotate, the support member can slide along the second plate into or out of the receiving groove to accommodate changes in distance between the first and second plates caused by rotation, preventing excessive support from the support member against the first and second plates and thus avoiding deformation.

[0047] like Figure 1 As shown, a top plate assembly 100 according to an embodiment of the present invention includes a first plate 110, a second plate 120 and a support member 130.

[0048] Specifically, the first plate 110 has a first rotation axis X, and the first plate 110 is capable of rotating about the rotation axis to rotate between an unfolded position and a folded position. The second plate 120 is located on one side of the first plate 110, such as... Figure 3 As shown, a storage area 111 is formed on one side of the first plate 110. Figure 3 The dashed line in the diagram represents the storage area 111, one side of which coincides with the first plate 110. At least a portion of the second plate 120 is located within the storage area 111; that is, the second plate 120 at least partially coincides with the first plate 110, and at least a portion of the orthographic projection of the second plate 120 onto the plane containing the first plate 110 lies on the first plate 110. The second plate 120 has a second rotation axis Y, and the second plate 120 is capable of rotating about the second rotation axis Y between an unfolded position and a folded position. The first rotation axis X and the second rotation axis Y are not coaxial.

[0049] like Figure 5 As shown, the support member 130 is disposed on the first plate 110 and contacts the second plate 120 to separate the first plate 110 and the second plate 120 from each other. During the rotation of the first plate 110 and the second plate 120, the support member 130 remains in contact with the first plate 110 and the second plate 120 to support the first plate 110 and the second plate 120, so that the distance between the first plate 110 and the second plate 120 is greater than or equal to zero, thus preventing the first plate 110 and the second plate 120 from interfering with each other or deforming due to factors such as the difference in rotational speed and gravity.

[0050] The second plate 120 is provided with a storage groove 121, and the storage groove 121 has an opening facing the first plate 110. When the first plate 110 rotates about the first rotation axis X and the second plate 120 rotates about the second rotation axis Y, the support member 130 can slide into or out of the storage groove 121 along the second plate 120. It is understood that since the first rotation axis X and the second rotation axis Y are not coaxial, and at least a part of the second plate 120 is located in the storage area 111, when the first plate 110 and the second plate 120 rotate, the distance between the side of the first plate 110 facing the second plate 120 and the side of the second plate 120 facing the first plate 110 changes with the rotation angle. In addition, due to the influence of gravity, the first plate 110 and the second plate 120 are prone to interference and mutual compression, which can cause the first plate 110 and the second plate 120 to deform and be damaged. By providing a storage slot 121, and allowing the support member 130 to enter or leave the storage slot 121 during the rotation of the first plate 110 and the second plate 120, the distance between the first plate 110 and the second plate 120 changes due to rotation, thus preventing the support member 130 from excessively supporting the first plate 110 and the second plate 120. Furthermore, when the support member 130 enters the storage slot 121, the distance between the first plate 110 and the second plate 120 decreases, reducing the space occupied by the first plate 110 and the second plate 120 and facilitating storage. Specifically, when both the first plate 110 and the second plate 120 are in the folded position, part of the support member 130 is located within the storage slot 121, thereby reducing the distance between the first plate 110 and the second plate 120, reducing the thickness of the top plate assembly 100, and increasing the folding rate, thus facilitating the storage and transportation of mobile buildings. In addition, the support member 130 requires a certain amount of thrust to slide out of the storage slot 121. Thus, when the top plate assembly 100 is folded and stored, the storage slot 121 provides a certain resistance to the support member 130, preventing the first plate 110 and the second plate 120 from being vibrated and sliding relative to each other during transportation.

[0051] According to the embodiment of the present invention, the top plate assembly 100 provides support by disposing a support member 130 between the first plate 110 and the second plate 120, with the support member 130 in contact with the second plate 120. This separation of the first plate 110 and the second plate 120 prevents them from being squeezed or deformed due to differences in rotational speed or gravity, thus extending the service life of the top plate assembly 100. Furthermore, when the first plate 110 and the second plate 120 rotate, the support member 130 can slide along the second plate 120 into or out of the receiving groove 121 to accommodate changes in distance between the first plate 110 and the second plate 120 caused by rotation, preventing the support member 130 from excessively supporting the first plate 110 and the second plate 120 and causing deformation.

[0052] According to some embodiments of the present invention, the second plate 120 can move relative to the first plate 110 to move into or away from the storage area 111. The movement of the second plate 120 relative to the first plate 110 can move the support member 130 to the location of the storage groove 121, so that when the first plate 110 and the second plate 120 rotate to the unfolded position, the support member 130 can slide along the second plate 120 into the storage groove 121. Specifically, the second plate 120 is movable relative to the first plate 110 between a first position and a second position. When the second plate 120 is in the first position, the portion of the second plate 120 within the storage area 111 accounts for the largest proportion of its own volume. When the second plate 120 is in the second position, the portion of the second plate 120 within the storage area 111 accounts for the smallest proportion of its own volume. It can be understood that when the second plate 120 is in the second position, at least a portion of the second plate 120 is located within the storage area 111, that is, at least a portion of the second plate 120 overlaps with at least a portion of the first plate 110, thus providing a shielding effect to prevent rainwater from seeping in through the gap between the first plate 110 and the second plate 120. Figure 2 As shown, the storage slot 121 is located at the end of the second plate 120 away from the first plate 110. The second plate 120 moves toward the storage area 111 so that the support member 130 moves toward the location of the storage slot 121.

[0053] like Figure 2 and Figure 6 As shown, according to some embodiments of the present invention, a transition slope 122 is formed on the peripheral wall of the receiving groove 121. The transition slope 122 extends obliquely from the opening of the receiving groove 121 to the bottom of the receiving groove 121, so that the transition slope 122 has a certain slope. The support member 130 can slide into or out of the receiving groove 121 along the transition slope 122, thereby making the sliding of the support member 130 within the receiving groove 121 and between the surface of the second plate 120 smoother. Furthermore, the sliding of the support member 130 on the transition slope 122 adapts to the gradual change in the distance between the first plate 110 and the second plate 120 during rotation, ensuring that the support member 130 remains in contact with the second plate 120. Figure 1 and Figure 7 As shown, where, Figure 7 The top panel assembly 100 is in a retracted state. Both the first panel 110 and the second panel 120 are in the retracted position. The second panel 120 is located in a second position relative to the first panel 110. The area of ​​the first panel 110 is larger than the area of ​​the second panel 120. When the top panel assembly 100 is retracted, the second panel 120 is located inside the first panel 110. Figure 1As shown, the transition slope 122 can be located on the side wall of the storage groove 121 away from the second rotation axis Y. When the support member 130 moves outside the storage groove 121, the support member 130 is located on the side of the storage groove 121 away from the fixed top plate 200.

[0054] like Figure 1 As shown, according to some embodiments of this utility model, the storage groove 121 is located at the end of the second plate 120 away from the second rotation axis Y, and the support member 130 is located at the end of the first plate 110 away from the first rotation axis X. It is understood that the ends of the first plate 110 and the second plate 120 away from the second rotation axis Y lack support points and are prone to deformation and interference under gravity. By placing the support member 130 at the end of the first plate 110 away from the fixed top plate 200, support points are increased, supporting the first plate 110 and the second plate 120, reducing deformation of the first plate 110 and the second plate 120, and avoiding interference between them.

[0055] like Figure 6 As shown, according to some embodiments of the present invention, the support member 130 includes a mounting base 131 and a rolling element 132. The mounting base 131 is connected to the first plate 110. The mounting base 131 can be fixedly connected to the first plate 110 by fasteners, or the mounting base 131 and the first plate 110 can be welded together. The rolling element 132 is rotatably connected to the mounting base 131. The rolling element 132 protrudes from the side of the first plate 110 facing the second plate 120 and contacts the second plate 120. The rolling element 132 contacts the second plate 120 and can slide along the second plate 120. In some embodiments, the rolling element 132 is a ball bearing. The mounting base 131 is provided with a mounting groove, the opening of which faces the side where the second plate 120 is located. The rolling element 132 is disposed in the mounting groove, and at least a portion of the rolling element 132 protrudes from the mounting groove. The support member 130 may also include an elastic member, which may be a spring. The elastic member is located between the rolling member 132 and the bottom of the mounting groove. When the first plate 110 and the second plate 120 rotate and the distance between them changes, the elastic member may contract or extend to adjust the size of the part of the rolling member 132 protruding from the mounting groove to adapt to the change in distance between the first plate 110 and the second plate 120.

[0056] like Figure 6As shown, according to some embodiments of the present invention, the support member 130 further includes a reinforcing plate 133, which can be a steel plate. The reinforcing plate 133 is fixedly connected to the first plate body 110, and the mounting base 131 is connected to the reinforcing plate 133 to improve the connection strength between the support member 130 and the first plate body 110. The first plate body 110 may include a support frame 112 and a cover plate 113. The cover plate 113 is connected to the support frame 112, and the reinforcing plate 133 is connected to the support frame 112 to improve the connection strength and support strength. In some embodiments, there are at least two support members 130, which are distributed along a direction perpendicular to the rotation axis of the first plate body 110 to reduce the pressure on a single support member 130.

[0057] A mobile building according to this utility model includes a main body, a fixed top plate 200, and at least one top plate assembly 100 as described above. The main body includes walls and a base plate, and the main body encloses to form the lower space of the mobile building. The fixed top plate 200 is connected to the main body and is located on top of the main body. A first plate 110 and a second plate 120 are both rotatably connected to the fixed top plate 200, and a first rotation axis X and a second rotation axis Y are both located on the fixed top plate 200 and on the same side of the fixed top plate 200.

[0058] According to some embodiments of this utility model, the fixed top plate 200 includes a first fixed plate 201 and a second fixed plate 202 connected to each other. The first plate body 110 is rotatably connected to the first fixed plate 201, and a first rotation axis is located on the first fixed plate 201. The second plate body 120 is rotatably connected to the second fixed plate 202, and a second rotation axis is located on the second fixed plate 202. The second fixed plate 202 can move relative to the first fixed plate 201 to drive the second fixed plate 202 to move into or away from the storage area 111.

[0059] Specifically, such as Figure 8 As shown, the fixed top plate 200 includes a first fixed plate 201 and a second fixed plate 202. The first fixed plate 201 and the second fixed plate 202 are slidably connected. The second fixed plate 202 is located on one side of the first fixed plate 201, and the second fixed plate 202 and the first fixed plate 201 at least partially overlap. The first fixed plate 201 is connected to the first plate body 110, and the second fixed plate 202 is connected to the second plate body 120. When the second fixed plate 202 slides relative to the first fixed plate 201, it drives the second plate body 120 to move relative to the first plate body 110, so that the second plate body 120 moves into or away from the storage area 111.

[0060] In some embodiments, the mobile building has a folded state and an unfolded state. When the mobile building is in the folded state, the orthographic projection of the second fixing plate 202 onto the plane of the first fixing plate 201 falls within the first fixing plate 201, and both the first plate body 110 and the second plate body 120 are in the folded position, with the second plate body 120 stored within the storage area 111. When the mobile building is in the unfolded state, at least a portion of the orthographic projection of the second fixing plate 202 onto the plane of the first fixing plate 201 falls outside the first fixing plate 201, and both the first plate body 110 and the second plate body 120 are in the unfolded position, with at least a portion of the second plate body 120 located outside the storage area 111.

[0061] like Figure 7 and Figure 8 As shown, where, Figure 7 China Mobile's building is in a retracted state. Figure 8 The mobile building is in its deployed state. A set of roof panel assemblies 100 are connected to both the left and right sides of the fixed roof panel 200. The same set of roof panel assemblies 100 are located on the same side of the fixed roof panel 200. For the roof panel assembly 100 located on the left side of the fixed roof panel 200, both the first rotation axis X and the second rotation axis Y are located on the left side of the fixed roof panel 200; for the roof panel assembly 100 located on the right side of the fixed roof panel 200, both the first rotation axis X and the second rotation axis Y are located on the right side of the fixed roof panel 200. The first plate 110 of each set of roof panel assemblies 100 is rotatably connected to the first fixed plate 201, and the second plate 120 of each set of roof panel assemblies 100 is rotatably connected to the second fixed plate 202.

[0062] like Figure 8 As shown, when the top plate assembly 100 is in the unfolded state, the second fixing plate 202 is away from the first fixing plate 201, the second plate body 120 is in the second position, and both the first plate body 110 and the second plate body 120 are rotated to the unfolded position. The first plate body 110 and the second plate body 120 are parallel or approximately parallel to the fixed top plate 200. When the top plate assembly 100 is retracted, the second fixing plate 202 moves towards the first fixing plate 201, causing the second plate body 120 to move to the first position. During this process, the support member 130 remains in contact with and slides relative to the side surface of the second plate body 120 facing the first plate body 110. Then, both the first plate 110 and the second plate 120 rotate downwards and move toward the folded position. The distance between the first plate 110 and the second plate 120 decreases, and the support member 130 slides along the transition slope 122 into the receiving groove 121 to adapt to the change in distance between the first plate 110 and the second plate 120. This ensures that the support member 130 remains in contact with the second plate 120 during the rotation of the first plate 110 and the second plate 120, providing support for the first plate 110 and the second plate 120 and preventing the first plate 110 and the second plate 120 from interfering with each other.

[0063] In summary, the top plate assembly 100 provided by this utility model embodiment provides support by placing a support member 130 between the first plate 110 and the second plate 120, with the support member 130 in contact with the second plate 120. This provides support force and maintains a certain distance between the first plate 110 and the second plate 120, preventing them from being squeezed or deformed due to differences in rotational speed, gravity, or other factors, thus extending the service life of the top plate assembly 100. When the first plate 110 and the second plate 120 rotate relative to the fixed top plate 200, the support member 130 can slide along the transition slope 122 to move into or away from the storage groove 121, thereby adapting to changes in the distance between the first plate 110 and the second plate 120 during rotation.

[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.
