Description

Technical Field

[0001] This invention relates to the field of science education technology, and in particular to a box structure for mobile display, belonging to the category of science education devices. Background Technology

[0002] To promote public science education and improve the scientific literacy of the entire population, mobile science museums have emerged. These mobile museums, using modularly designed exhibits and activities, travel to counties and areas that do not yet have science museums.

[0003] However, the exhibits currently used in mobile science museums are mostly modular, consisting of an upper box, a lower box, and a display stand. During setup, manual labor is required to move the exhibits to the designated location, disassemble and reassemble the upper and lower boxes, and secure the display stand with screws. Dismantling also requires disassembling the components, resulting in a large number of transportable parts. Furthermore, due to the modular structure, the upper and lower boxes must be secured with cable ties during transport. All of these factors significantly increase labor and time costs. Summary of the Invention

[0004] In order to address the aforementioned shortcomings of current mobile science museum display cases, this invention provides a case structure for mobile displays that enables a single person to quickly set up an exhibition, greatly saving labor, time, and transportation costs incurred during the setup process.

[0005] The technical solution of this invention is a box structure for mobile display, comprising a cover plate, a box body, an equipment box, an electric lifting platform, and a support. The cover plate is flat and positioned above the box body, connected to a sliding groove limiting structure at the top of the support via a flip-up limiting structure at its lower end. The box body is a hollow, enclosed frame structure with walls of a certain thickness, featuring a rounded rectangular opening at the top, handles on the left and right sides of the exterior, linear slide rails on the left and right sides of the internal back panel, a first limit switch and a second limit switch at the top and bottom, and four circular openings at the bottom. The equipment box has a flat, thick tabletop at the top, with the same size and shape as the rounded rectangular opening at the top of the box body, and a hollow, frame-shaped equipment box at the bottom. The electric lifting platform is located inside the box body and fixed to the bottom of the box body with screws. The bottom of the support is connected to the upper plate of the electric lifting platform with screws, extending through holes in the support and exiting the box body. The equipment box is positioned above the electric lifting platform.

[0006] The cover plate consists of a main board surface, a fixing lock, a flip-limiting structure, and a C-shaped limiting block. The main board surface is a flat, rounded rectangular high-strength material panel, and its length and width dimensions are between the upper surface of the box and the rounded rectangular opening.

[0007] The flip-limiting structure has a rectangular limiting block at the top, the thickness of which is less than the thickness of the cover plate, a circular metal rod in the middle, and a limiting ball at the bottom.

[0008] The C-shaped limiting blocks are located at the four corners of the main board surface, symmetrically distributed, and slightly protrude from the main board surface. The shape and size of the outline formed by their combination match the shape and size of the rounded rectangular opening at the top of the box.

[0009] The electric lifting platform comprises a base, an upper plate, a lifting assembly, an electric push rod, and casters.

[0010] The upper part of the lifting assembly is connected to the upper plate, and the lower part is connected to the bottom plate.

[0011] The upper part of the electric push rod is connected to the lifting assembly, and the bottom part is connected to the base plate.

[0012] The casters are connected to the bottom of the upper plate by screws and are located at the four corners of the bottom of the upper plate.

[0013] The bracket has a sensor at the bottom, a linear slider at the back, and a sliding groove limiting structure at the top. The bottom of the bracket is connected to the rear of the upper plate of the electric lifting platform by screws.

[0014] The linear slider is connected to the linear guide rail inside the housing.

[0015] The sliding groove limiting structure has rectangular limiting grooves on the left and right sides, which are the same in shape and size as the rectangular limiting block. A through U-shaped sliding groove is provided in the middle, and a first ball limiting groove and a second ball limiting groove are provided behind and below the sliding groove, respectively.

[0016] The beneficial effects of this invention during mobile exhibitions are as follows: 1. This invention mainly comprises five components: a cover plate, a housing, an equipment box, an electric lifting platform, and a support frame. The housing serves as an exhibition stand when in the display state, and when closed, it cooperates with the cover plate to form a sealed unit for use as a packaging box. During movement, the linear slider on the support frame engages with the linear guide rail on the back panel of the housing, ensuring a smooth and stable lifting path. All components are connected by screws, making the structural connections more stable. Exhibits are more securely housed within the housing compared to traditional split-type housings during transportation.

[0017] 2. When the invention is in the closed state, the electric lifting platform will be at its lowest position, and the casters will protrude from the lowest surface of the box, so only one person is needed to push and transport the exhibits.

[0018] 3. When this invention needs to be exhibited, the electric lifting platform is raised to a high position, with the platform panel of the equipment box slightly protruding above the upper surface of the box, so that the entire exhibit is fully exposed within the display area. The casters follow the electric lifting platform as it rises, and the bottom of the box touches the ground. This step can be performed on individual exhibits, or all exhibits can be placed in the designated position and then operated as a whole, achieving one-click setup without the need for flipping, assembling, or disassembling each exhibit as required by traditional modular display cases.

[0019] 4. This invention incorporates a flipping limiting structure and a sliding groove limiting structure, enabling flipping in both horizontal and vertical directions. The mechanical limiting and locking mechanism is simple, provides a secure lock, and facilitates operation. Furthermore, in the horizontal position, both structures are on the same horizontal plane, resulting in an aesthetically pleasing appearance.

[0020] Two states are achieved by flipping the cover plate: In the first state, when flipped to a horizontal position, it acts as a cover to protect the exhibits during closed transport.

[0021] In the second configuration, the display stand is flipped vertically and used as a graphic display board when the exhibit is unfolded. Because the stand extends to a certain height, the exhibit will not obstruct the graphic content. This method eliminates the hassle of having to install and disassemble each exhibit's graphic display stand individually.

[0022] The container structure for mobile displays described in this invention, compared to existing split-type mobile exhibition containers, eliminates the need for reconnecting the upper and lower containers with each flip, making the entire container a single unit. This reduces the possibility of damage to exhibits during handling and transportation. By combining the graphic display stand and the cover plate into one, the hassle of installing, disassembling, and transporting the graphic display stand is eliminated, reducing the total number of transport and handling components by half, significantly reducing labor and time costs. The efficient use of casters makes the handling process easier and greatly shortens the setup and dismantling time. Attached Figure Description

[0032] The scheme will now be described in detail with reference to the accompanying drawings.

[0033] like Figure 1-5 As shown, the technical solution of the present invention is a box structure for mobile display, comprising a cover plate 1, a box body 2, an equipment box 3, an electric lifting platform 4, and a support 5. The cover plate 1 is flat and positioned above the box body 2, connected to the sliding groove limiting structure 53 at the top of the support 5 via a flip-limiting structure 13 at its lower end. The box body 2 is a hollow, enclosed frame structure with walls of a certain thickness. It has a rounded rectangular opening 21 and a support hole 27 at the top, handles 22 on the left and right sides of the exterior, and linear slide rails 23 on the left and right sides of the internal back panel. The top and bottom are respectively equipped with... The equipment box 3 is equipped with a first limit switch 24 and a second limit switch 25. It has four circular openings 26 at the bottom. The top of the equipment box 3 is a flat plate 31 with a certain thickness. Its overall size and shape are the same as the rounded rectangular opening 21 at the top of the box 2. The bottom is a hollow frame-shaped equipment box 32. The electric lifting platform 4 is located inside the box 2 and is fixed to the bottom of the box 2 with screws. The bottom of the bracket 5 is connected to the upper plate 42 of the electric lifting platform 4 with screws and passes through the bracket hole 27 to the box 2. The equipment box 3 is set above the electric lifting platform 4.

[0034] The cover plate 1 comprises a main board surface 11, a fixing lock 12, a flip-limiting structure 13, and a C-shaped limiting block 14.

[0035] The main board surface 11 is a flat, rounded rectangular high-strength material panel.

[0036] The flip-limiting structure 13 has a rectangular limiting block 131 at the top, the thickness of which is less than the thickness of the cover plate 1, a circular metal rod 132 made of metal in the middle, and a limiting ball 133 at the bottom.

[0037] The C-shaped limiting blocks 14 are located at the four corners of the main board surface 11, symmetrically distributed, and slightly protrude from the main board surface 11. The outer shape and size of the combination are consistent with the shape and size of the rounded rectangular opening 21 on the top of the box body 2.

[0038] like Figure 6 , 7 As shown, the electric lifting platform 4 comprises a base 41, an upper plate 42, a lifting assembly 43, an electric push rod 44, and casters 45.

[0039] The upper part of the lifting assembly 43 is connected to the upper plate 42, and the lower part is connected to the bottom plate 41.

[0040] The upper part of the electric push rod 44 is connected to the lifting assembly 43, and the bottom part is connected to the base plate 41.

[0041] The casters 45 are connected to the bottom of the upper plate 42 by screws and are located at the four corners of the bottom of the upper plate 42.

[0042] The bracket 5 is equipped with a sensor 51 at the bottom, a linear slider 52 at the back, and a sliding groove limiting structure 53 at the top. The bottom of the bracket 5 is connected to the rear of the upper plate of the electric lifting platform 4 by screws.

[0043] The linear slider 51 is connected to the linear slide rail 52 inside the housing 2.

[0044] like Figure 8 As shown, the sliding groove limiting structure 53 has rectangular limiting grooves 531 on the left and right sides, which are the same in shape and size as the rectangular limiting block 131. A through U-shaped sliding groove 532 is provided in the middle. A first ball limiting groove 533 and a second ball limiting groove 534 are provided behind and below the sliding groove, respectively.

[0045] The specific implementation examples are described below with reference to the accompanying drawings: like Figure 1-8As shown, when the exhibit needs to be displayed, it is powered on and the locking mechanism 12 is unlocked. The electric push rod 44 is shortened via remote control or switch, pulling the lifting assembly 43 to raise the upper plate 42. The sensor 51 moves upward along the linear guide rail with the bracket 5. When it reaches a certain position, the sensor 51 triggers the first limit switch 24, stopping the electric push rod 43 from shortening and locking it. The panel 31 of the equipment box 3 is positioned slightly above the upper plane of the box 2, fully exposing the exhibit within the display area. The casters 45 rise with the electric lifting platform 4, and the bottom of the box 2 touches the ground. During the above process, the bracket, through the bracket hole 27, moves the cover plate 1 upward along with the automatic lifting platform 4. After the state is locked, the cover plate 1 is flipped from the horizontal position to the vertical direction. The limiting ball 133 on the cover plate 1 disengages from the first ball limiting groove 533. When the cover plate 1 is flipped to the vertical direction, the circular metal rod 132 slides down the through-type U-shaped slide groove 532 from top to bottom to the lowest position. At the same time, the rectangular limiting block 131 is inserted into the rectangular limiting groove 531, and the limiting ball 133 slides into the second ball limiting groove 534 and is fixed, so that the cover plate 1 and the bracket 5 are locked in the vertical direction. The exhibition state of the present invention is completed.

[0046] Similarly, when exhibits need to be dismantled, the cover plate 1 pulls the rectangular limiting block 131 out of the rectangular limiting groove 531 from the vertical direction upwards, and the limiting ball 133 slides out from the second ball limiting groove 534. When the circular metal rod 132 slides from bottom to top along the through U-shaped slide groove 532 to the highest position, it flips the cover plate from the vertical position to the horizontal position. When flipped to the horizontal position, the limiting ball 133 slides into the first ball limiting groove 533, and the bottom end of the rectangular limiting block 131 fits with the front outer surface of the bracket 5, realizing the horizontal locking position of the cover plate 1 and the bracket 5. The electric push rod 44 is controlled by the remote control or switch to increase the stroke, pushing the lifting component 43 to drive the upper plate 42 to descend. When the bracket 5 descends to a certain position, the sensor 51 triggers the second limit switch 25, the electric push rod 43 stops its extension movement and is in a locked state. This drives the equipment box 3 and exhibits to completely descend into the box 2. The C-shaped limiting block 14 of the cover plate 1 engages with the rounded rectangular opening 21 of the box body 2, locking it in place. Due to the locking of the flip-limiting structure 13 and the sliding groove limiting structure 53, the cover plate 1 and the box body 2 are tightly closed, protecting the exhibits. The casters 45 descend with the electric lifting platform 4, eventually reaching below the bottom surface of the box body 2, allowing for the pushing and transport of the exhibits. The closed state of the invention is now complete.
