[0002] Building Information Modeling (BIM) has become one of the core concepts in the field of building information technology in recent years, with its data foundation being a three-dimensional information model of the building. Compared to traditional two-dimensional design and drafting, BIM technology fully utilizes three-dimensional graphics technology, using the three-dimensional graphics of the building (building components and the building as a whole) as a carrier to further connect various building information parameters, forming a BIM model, and then managing the entire lifecycle of the building, and even its components. With the digital data of the BIM model as the core, through mobile hardware carriers (such as portable terminals and mobile display stands) or lightweight technologies, it enables on-site display, interactive operation, and multi-terminal collaboration of the BIM model, suitable for various stages such as architectural design communication, construction handover, and project acceptance.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides a portable display device based on BIM (Building Information Modeling), such as... Figures 1 to 8As shown, the device includes a display screen 1, a mounting base 2, first moving wheels 3, a mounting plate 4, and an adjustment device. The mounting base 2 is fixedly connected to the bottom of the display screen 1 to support and fix the display screen 1. The first moving wheels 3 are located on both sides of the bottom of the mounting base 2 to move the display screen 1 and the mounting base 2. The mounting plate 4 is fixedly connected to the top of the first moving wheels 3 to connect the first moving wheels 3 and the mounting base 2. The adjustment device is located inside the mounting base 2 to house and protect the first moving wheels 3. The adjustment device includes a rotating rod 5, a slider 6, a first electric push rod 7, a fixed plate 8, and a second moving wheel 9. The rotating rod 5 is fixedly connected to both ends of the mounting plate 4. The slider 6 is rotatably connected to the side of the rotating rod 5 away from the mounting plate 4, so that the mounting plate 4 can drive the first moving wheels 3 to rotate and adjust the direction. The inner walls of both sides of the mounting base 2... All are provided with sliding grooves, and the slider 6 is slidably connected to the sliding grooves, which is used to drive the first moving wheel 3 of the mounting plate 4 to move into the mounting base 2. Two first electric push rods 7 are fixedly connected to the top inner wall of the mounting base 2. The bottom of the first electric push rod 7 is fixedly connected to the fixing plate 8. The bottom of the fixing plate 8 is fixedly connected to the second moving wheel 9. The first moving wheel 3 is located at both ends of the mounting plate 4. The mounting plate 4 is symmetrically arranged on both sides of the mounting base 2. One end of the mounting plate 4 is located inside the mounting base 2, and the other end extends to the outside of the mounting base 2. Two movable openings 10 are opened at the bottom of the mounting base 2. The second moving wheel 9 is located in the movable opening 10. Baffles 11 are provided on both sides of the top of the movable opening 10. The baffles 11 are fixedly connected to the inner wall of the mounting base 2. The first electric push rod 7, the fixing plate 8 and the second moving wheel 9 are all located between the two baffles 11.

[0021] The mounting plate 4 facilitates the installation of the first moving wheel 3 onto the mounting base 2. The first moving wheel 3 then drives the mounting base 2 and the display screen 1 to move, allowing for easy adjustment of the display screen 1's position. The mounting base 2 facilitates the installation of the first electric push rod 7 and the second moving wheel 9. When the first moving wheel 3 encounters uneven surfaces such as grass, mud, or cracks in paving stones, and becomes stuck or damaged, the second moving wheel 9 can be used to switch it off, allowing the second moving wheel 9 to continue driving the mounting base 2 and the display screen 1, thus improving movement efficiency. The baffle 11 protects the first electric push rod 7 and the second moving wheel 9 from damage, preventing them from affecting the second moving wheel 9's performance. When passing through elevator shafts or corridors, the display screen 1 cannot move due to the restriction imposed by the mounting plate 4 and the first moving wheel 3. When the device can be flexibly turned or placed, or even when it cannot enter, first activate the first electric push rod 7 to push the second moving wheel 9 through the movable opening 10 to move to the ground, supporting the mounting base 2 and the display screen 1. Then rotate the mounting plate 4, causing the mounting plate 4 to drive the first moving wheel 3 and the rotating rod 5 to rotate along the slider 6, so that the mounting plate 4 and the first moving wheel 3 rotate from the horizontal direction to the vertical direction. Then push the mounting plate 4, causing the mounting plate 4 to drive the rotating rod 5 and the first moving wheel 3 to move the slider 6 along the slide groove into the mounting base 2, until it moves to both sides of the baffle 11, so that the mounting plate 4 and the first moving wheel 3 move into the mounting base 2 for storage and protection, preventing the first moving wheel 3 from being hit when the display screen 1 moves or causing the already damaged first moving wheel 3 to be hit again, affecting its use. Then push the display screen 1, the mounting base 2, and the second moving wheel 9 to move, making it easier to pass through narrow spaces.

[0022] like Figures 1 to 4 As shown, the adjustment device also includes a protective limiting component, which includes a protective plate 12, a pull block, and a magnetic structure. The protective plate 12 is provided on the side of the baffle 11 away from the second moving wheel 9. A pull block is fixedly connected to one side of the protective plate 12. Both sides of the protective plate 12 are slidably connected to the inner wall of the mounting base 2. The bottom of the protective plate 12 is located at the top of the mounting plate 4. A limiting groove is opened at the bottom of the display screen 1. The protective plate 12 passes through the top of the mounting base 2 and is inserted into the limiting groove. A magnetic structure is provided on the side of the mounting plate 4 away from the baffle 11 and the top inner wall of the mounting base 2.

[0023] The protective plate 12 provides protection on both sides of the mounting base 2, preventing mud, gravel, and debris from entering the interior of the mounting base 2 and damaging its internal structure. This would ensure the stability of the mounting base 2, display screen 1, and first moving wheel 3. When the first moving wheel 3 needs to be protected, first pull the lever to move the protective plate 12 through the top of the mounting base 2 and into the limiting slot, thus no longer obstructing or protecting the mounting base 2. Then, push the mounting plate 4 and the first moving wheel 3 to rotate, so that the mounting plate 4 and the first moving wheel 3 rotate from the horizontal direction to the vertical direction. Under the action of the slider 6, the mounting plate 4 and the first moving wheel 3 move into the mounting base 2. Then, move the lever downward to move the protective plate 12 to the top of the first moving wheel 3, continuing to protect both sides of the mounting base 2 and preventing foreign objects from entering the interior of the mounting base 2. This improves the service life of the internal structure of the mounting base 2 and facilitates its use.

[0024] like Figures 3 to 6 As shown, the magnetic attraction structure includes a first magnetic block 14, a telescopic rod 15, and a second magnetic block 16. A groove is provided on the side of the mounting plate 4 away from the slider 6. The first magnetic block 14 is fixedly connected inside the groove. The telescopic rod 15 is fixedly connected to the top inner wall of the mounting base 2. The second magnetic block 16 is fixedly connected to the bottom of the telescopic rod 15. The first magnetic block 14 and the second magnetic block 16 are magnetically connected. The telescopic rod 15 and the second magnetic block 16 are located between the baffle 11 and the protective plate 12. The first telescopic rod 15 and the second magnetic block 16 are located at the top two ends of the baffle 11 and are symmetrically arranged with respect to the center of the mounting base 2. A first spring 17 is provided inside the telescopic rod 15. One end of the first spring 17 is fixedly connected to the top inner wall of the telescopic rod 15, and the other end is fixedly connected to the second magnetic block 16.

[0025] When the mounting plate 4 and the first moving wheel 3 rotate from the horizontal direction to the vertical direction, and push the mounting plate 4 and the first moving wheel 3 to move, the rotating rod 5 drives the slider 6 to move along the slide groove to one side of the baffle 11. Then, the first magnetic block 14 on one side of the mounting plate 4 moves to the bottom of the second magnetic block 16. Through the magnetic attraction of the first magnetic block 14 and the second magnetic block 16, the telescopic rod 15 extends and the first spring 17 is stretched. Thus, the mounting plate 4 is fixed in the mounting base 2 under the action of the first magnetic block 14 and the second magnetic block 16, so that the position of the mounting plate 4 and the first moving wheel 3 remains stable. This prevents the mounting plate 4 and the first moving wheel 3 from shaking when the mounting base 2 moves, and thus slipping to the outside of the mounting base 2, affecting the movement of the display screen 1 and the mounting base 2.

[0026] like Figures 5 to 7As shown, a first fixing block 18 is fixedly connected to the bottom of the mounting base 2, and a connecting block 19 is fixedly connected inside the first fixing block 18. The top of the connecting block 19 is fixedly connected to the bottom of the mounting base 2. A second electric push rod 20 is fixedly connected to both sides of the connecting block 19. A limiting groove is opened on the side of the second moving wheel 9 near the first fixing block 18. One end of the second electric push rod 20 passes through one side of the first fixing block 18 and is inserted into the limiting groove. The first fixing block 18 is located at both ends of the bottom of the mounting base 2 and is located between the two first moving wheels 3. Two second fixing blocks 21 are provided on the side of the movable opening 10 away from the first fixing block 18. A fixing structure is provided on the side of the connecting block 19 and inside the second fixing block 21. The diameter of the fixing plate 8 is larger than the diameter of the movable opening 10. Fixing grooves 30 are opened on both sides of the top of the second moving wheel 9.

[0027] The first fixing block 18 and connecting block 19 facilitate the installation and protection of the second electric push rod 20, preventing it from being bumped or damaged at the bottom of the mounting base 2, thus affecting the fixing effect on the first moving wheel 3. The second electric push rod 20 is used to insert and limit the two sides of the first moving wheel 3, improving the stability of the first moving wheel 3 and the mounting plate 4 at the bottom of the mounting base 2, facilitating the movement of the mounting base 2 and the display screen 1. When the second electric push rod 20 is activated, it moves the fixing plate 8 and the second moving wheel 9 downward, causing the second moving wheel 9 to pass through the movable opening 10 and move towards the ground. When the fixing plate 8 moves to the top of the movable opening 10 and fits against the inner wall of the bottom of the mounting base 2, the second moving wheel 9 moves to the ground. At the same time, the fixing rod 24 in the fixing structure is inserted into the fixing groove 30, limiting the position of the second moving wheel 9, thereby improving the stability of the second moving wheel 9 and preventing it from shaking during movement, which would affect the stability of the movement of the mounting base 2 and the display screen 1.

[0028] like Figures 5 to 8As shown, the fixing structure includes a movable block 22, a compression spring 23, a fixing rod 24, a protrusion 25, a movable rod 26, and a movable plate 27. The movable block 22 is located inside the first fixing block 18 and the second fixing block 21 near the movable opening 10. The movable block 22 is fixedly connected to the fixing rod 24. The first fixing block 18 and the second fixing block 21 have insertion holes on the side near the movable opening 10. The end of the fixing rod 24 away from the movable block 22 is located in the insertion hole. The movable block 22 has a movable opening on the side away from the fixing rod 24. The compression spring 23 is fixedly connected inside the movable opening. One end of the compression spring 23 is fixedly connected to the inner wall of the connecting block 19 and the second fixing block 21. The top of the movable block 22 is provided with a protrusion 25, and the top of the protrusion 25 is fixedly connected to... There is a movable rod 26, and a movable plate 27 is fixedly connected to the outside of the movable rod 26. The bottom of the mounting base 2 has a mounting groove, and the movable plate 27 is slidably connected to the mounting groove. The end of the movable block 22 near the compression spring 23 is inclined, and the protrusion 25 is located at the top of the inclined surface. The top of the movable plate 27 is fixedly connected to the second spring 28, which is located on both sides of the movable rod 26. The top of the second spring 28 is fixedly connected to the inner wall of the top of the mounting groove. The second compression spring 23 is in a compressed state. The fixed rod 24 is inserted into the fixed groove 30. The bottom of the fixed plate 8 is fixedly connected to the push rod 29, which is located on both sides of the second movable wheel 9. The number of push rods 29 is the same as the number of movable rods 26, and the push rods 29 are located at the top of the movable rod 26.

[0029] When the first electric push rod 7 drives the second moving wheel 9 to move downward, the fixed plate 8 drives the push rod 29 to move downward. When the fixed plate 8 moves to the top of the movable opening 10 and fits against the bottom inner wall of the mounting base 2, the second moving wheel 9 moves to the ground. At the same time, the push rod 29 pushes the moving rod 26 and the protrusion 25 to move downward, so that the moving plate 27 moves downward along the inner wall of the mounting groove and drives the second spring 28 to stretch. Since the protrusion 25 is located at the top of the inclined surface of the moving block 22, when the moving rod 26 drives the protrusion 25 to move downward, the protrusion 25 moves along the inclined surface of the moving block 22 and squeezes the moving block 22, so that the moving block 22 drives the fixed rod 24 to move along the bottom inner wall of the first fixed block 18 and the second fixed block 21, so that the compression spring 23 stretches. The fixed rod 24 passes through the insertion hole and is inserted into the fixed groove, limiting the two sides of the second moving wheel 9 after it moves, so that the second moving wheel 9 remains stable at the bottom of the mounting base 2, thereby facilitating the movement of the mounting base 2 and the display screen 1.

[0030] Working principle of this invention: Reference Figures 1 to 8As shown, by pushing the first moving wheel 3, the mounting base 2 and the display screen 1 are moved, and the position of the display screen 1 is adjusted for use. When the first moving wheel 3 encounters uneven surfaces such as grass, mud, or stone slab seams, and gets stuck and damaged, or when it needs to pass through elevator shafts or corridors, and the display screen 1 cannot be flexibly turned or placed due to the restriction of the mounting plate 4 and the first moving wheel 3, or even cannot enter, the first electric push rod 7 is activated to push the second moving wheel 9 through the movable opening 10 to the ground to support the mounting base 2 and the display screen 1. The second electric push rod 20 is activated to retract and move into the first fixed block 18, no longer supporting and fixing the first moving wheel 3. Pulling the pull block moves the protective plate 12 through the top of the mounting base 2 and inserts it into the limiting slot. Rotating the mounting plate 4 causes the first moving wheel 3 and the rotating rod 5 to rotate along the slider 6, so that the mounting plate 4... The first moving wheel 3 rotates from the horizontal to the vertical direction, and then pushes the mounting plate 4. This causes the mounting plate 4 to drive the rotating rod 5 and the first moving wheel 3, so that the slider 6 moves along the groove into the mounting base 2 until it moves to both sides of the baffle 11. At the same time, the first magnetic block 14 on one side of the mounting plate 4 moves to the bottom of the second magnetic block 16. Through the magnetic attraction between the first magnetic block 14 and the second magnetic block 16, the telescopic rod 15 extends and the first spring 17 stretches. This fixes the mounting plate 4 in the mounting base 2 under the action of the first magnetic block 14 and the second magnetic block 16, keeping the position of the mounting plate 4 and the first moving wheel 3 stable. After the mounting plate 4 and the first moving wheel 3 have moved into the mounting base 2 for storage and protection, the pull block is moved downwards to move the protective plate 12 to the top of the first moving wheel 3, continuing to protect both sides of the mounting base 2 and preventing foreign objects from entering the interior of the mounting base 2.

[0031] When the first electric push rod 7 drives the second moving wheel 9 to move downwards, the fixed plate 8 moves along the inner wall of the mounting base 2, and drives the push rod 29 to move downwards. When the fixed plate 8 moves to the top of the movable opening 10 and fits against the bottom inner wall of the mounting base 2, the second moving wheel 9 moves to the ground. Since the push rod 29 is located at the top of the moving rod 26, when the push rod 29 moves downwards, it pushes the moving rod 26 and the protrusion 25 downwards, causing the inner wall of the mounting groove of the moving plate 27 to move downwards, and driving the second spring 28 to stretch. Since the protrusion 25 is located at the top of the moving block 22, the second spring 28 stretches. At the top of the slope, when the moving rod 26 drives the protrusion 25 to move downward, the protrusion 25 moves along the slope of the moving block 22 and squeezes the moving block 22, causing the moving block 22 to drive the fixed rod 24 to move along the bottom inner wall of the first fixed block 18 and the second fixed block 21, causing the compression spring 23 to stretch, and the fixed rod 24 to be inserted into the fixed groove, limiting the two sides of the second moving wheel 9 after it moves, so that the second moving wheel remains stable at the bottom of the mounting base 2, and then pushes the display screen 1, the mounting base 2, and the second moving wheel 9 to move through the elevator shaft and corridor for use.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
