Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, and in particular to an integrated retractable smart mobile blackboard. Background Technology

[0002] Against the backdrop of the rapid development of educational informatization and intelligentization, smart mobile blackboards, as a new type of teaching equipment, are widely used in modern teaching scenarios due to their convenience and multifunctionality.

[0003] Traditional mobile blackboards mostly use fixed support structures, and height adjustment usually relies on manual knobs or levers, which are cumbersome to operate and have limited adjustment precision, making it difficult to meet the needs of teachers of different heights and diverse teaching scenarios. At the same time, the existing support structure of mobile blackboards presents a contradiction between stability and space storage. To ensure stability during use, the support area is large, resulting in excessive space occupation when not in use, causing inconvenience for transportation and storage; conversely, reducing the support area for easier storage results in an insufficient bottom support area, posing a risk of tipping over and affecting the lifespan and safety of the device. Therefore, developing an integrated retractable smart mobile blackboard with flexible height adjustment, stable support, and easy storage and relocation is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated retractable smart mobile blackboard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated retractable smart mobile blackboard includes a support plate, on the lower side of which support components are symmetrically arranged. Each support component includes a bidirectional threaded rod and a synchronous motor. A large gear is fixedly sleeved on the outer side of the middle of the bidirectional threaded rod, and a small gear is fixedly installed on the output end of the synchronous motor, meshing with the large gear. Rectangular sliding sleeves are symmetrically threaded onto the outer sides of both ends of the bidirectional threaded rod. An electric lifting rod is fixedly installed at the bottom of the rectangular sliding sleeves. A turntable is rotatably installed on the lower side of the output end of the electric lifting rod, and rollers are rotatably installed at the bottom of the turntable.

[0007] Furthermore, the outer sides of the large gear and the small gear are covered with protective covers, which are fixedly installed on the bottom of the support plate.

[0008] By adopting the above technical solution, the protective cover provides protection for the gear meshing space.

[0009] Furthermore, a connecting seat is fixedly connected to the upper side of the synchronous motor, and a sleeve is slidably fitted on the outer side of the rectangular sliding sleeve. Both the connecting seat and the sleeve are fixedly installed at the bottom of the support plate.

[0010] Furthermore, a stabilizing telescopic rod is fixedly connected between the outer walls of the two electric lifting rods.

[0011] By adopting the above technical solution, the stability of the telescopic boom is enhanced, thereby improving the structural stability between the two electric lifting booms.

[0012] Furthermore, an auxiliary stabilizing component is provided on the outer side of the roller. The auxiliary stabilizing component includes a sliding sleeve, which is slidably sleeved on the outer wall of the output end of the electric lifting rod. A buckle is fixedly installed at the bottom of the sliding sleeve, and the buckle covers the outer side of the turntable.

[0013] Furthermore, a plurality of hydraulic rods are fixedly installed on the upper side of the sliding sleeve, and a top seat is fixedly installed on the top of the hydraulic rods. The top seat is fixedly installed on the outer wall of the output end of the electric lifting rod.

[0014] By adopting the above technical solution, the hydraulic rod can be activated to push the cover downwards, so that the bottom of the cover touches the ground. The cover provides support and avoids the instability of the rollers when in static support.

[0015] Furthermore, a rubber gasket is fixedly installed at the bottom of the cover.

[0016] Furthermore, a mounting groove plate is fixedly installed on the upper side of the support plate, and a blackboard is fixedly installed on the front side of the mounting groove plate.

[0017] By adopting the above technical solution, the mounting plate provides a rear bottom support for the blackboard.

[0018] Furthermore, electrically retractable auxiliary plates are symmetrically slidably installed on both sides of the mounting groove plate.

[0019] Furthermore, a controller is fixedly installed on the upper side of the support plate.

[0020] By adopting the above technical solution, the electric retractable sub-plate can extend or retract from both sides of the mounting slot plate. When retracted, it reduces the overall volume and is easy to transport. When unfolded, it expands the usable area of ​​the teaching and writing area.

[0021] Compared with related technologies, the integrated retractable smart mobile blackboard proposed in this utility model has the following beneficial effects:

[0022] In this utility model, an integrated retractable smart mobile blackboard is constructed using a support assembly. Within this assembly, a synchronous motor drives a small gear to rotate, which in turn meshes with a large gear to further rotate a bidirectional threaded rod. This, in turn, drives rectangular sliding sleeves on both sides to move towards each other. As the rectangular sliding sleeves move away from each other, the distance between the two electric lifting rods at the bottom increases, thus enlarging the support surface area formed between the four electric lifting rods located under the support plate. This improves support stability and enhances the device's anti-overturning performance. When the rectangular sliding sleeves move closer together, the overall size of the support system shrinks, facilitating the retraction and storage of the entire device. Furthermore, rollers are provided at the bottom of the electric lifting rods to facilitate the movement and transport of the device, further enhancing the practicality of this utility model.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figures 1-5An integrated retractable smart mobile blackboard includes a support plate 1, with a support component 2 symmetrically arranged on the lower side of the support plate 1. The support component 2 includes a bidirectional threaded rod 22 and a synchronous motor 25. A large gear 23 is fixedly sleeved on the outer side of the middle of the bidirectional threaded rod 22. A small gear 26 is fixedly installed on the output end of the synchronous motor 25. The small gear 26 meshes with the large gear 23. Rectangular sliding sleeves 27 are symmetrically threaded on the outer sides of both ends of the bidirectional threaded rod 22. An electric lifting rod 29 is fixedly installed at the bottom of the rectangular sliding sleeve 27. A turntable 211 is rotatably installed on the lower side of the output end of the electric lifting rod 29. A roller 212 is rotatably installed at the bottom of the turntable 211.

[0031] In this embodiment, an auxiliary stabilizing component 7 is provided on the outer side of the roller 212. The auxiliary stabilizing component 7 includes a sliding sleeve 71, which is slidably sleeved on the outer wall of the output end of the electric lifting rod 29. A cover 74 is fixedly installed at the bottom of the sliding sleeve 71, which covers the outer side of the turntable 211. Several hydraulic rods 72 are fixedly installed on the upper side of the sliding sleeve 71. A top seat 73 is fixedly installed on the top of the hydraulic rods 72, which is fixedly installed on the outer wall of the output end of the electric lifting rod 29. A rubber gasket 75 is fixedly installed at the bottom of the cover 74.

[0032] With the above structure, when the device is moved to the use position, the hydraulic rod 72 is activated to drive the sliding sleeve 71 to slide downward on the outer wall of the output end of the electric lifting rod 29, thereby causing the cover 74 to abut against the ground, so that the bottom of the cover 74 plays a supporting role and avoids the instability of the roller 212 when statically supported.

[0033] In this embodiment, a mounting slot plate 4 is fixedly installed on the upper side of the support plate 1, a blackboard 5 is fixedly installed on the front side of the mounting slot plate 4, an electric retractable auxiliary plate 6 is symmetrically slidably installed on both sides of the mounting slot plate 4, and a controller 3 is fixedly installed on the upper side of the support plate 1.

[0034] With the above structure, the electric retractable sub-plate 6 can be retracted or expanded on both sides of the mounting slot plate 4, thereby increasing the usable area on both sides of the blackboard 5. In addition, the controller 3 controls the synchronous motor 25, electric lifting rod 29 and hydraulic rod 72 in this utility model to drive synchronously, so as to meet the adjustment and balance of the support system. An electric drive rod is provided between the inner end of the electric retractable sub-plate 6 and the inner side of the mounting slot plate 4, and the electric retractable sub-plate 6 is driven to retract or expand through the electric drive rod.

[0035] In this embodiment, a protective cover 21 is provided on the outer side of the large gear 23 and the small gear 26, and the protective cover 21 is fixedly installed at the bottom of the support plate 1.

[0036] Through the above structure, the protective cover 21 protects the stability of the gear meshing transmission space.

[0037] In this embodiment, a connecting seat 24 is fixedly connected to the upper side of the synchronous motor 25, and a sleeve 28 is slidably sleeved on the outer side of the rectangular sliding sleeve 27. Both the connecting seat 24 and the sleeve 28 are fixedly installed at the bottom of the support plate 1.

[0038] Through the above structure, the connecting seat 24 provides a supporting connection for the synchronous motor 25, and the sleeve 28 provides a sliding guide for the rectangular sliding sleeve 27.

[0039] In this embodiment, a stable telescopic rod 210 is fixedly connected between the outer walls of the two electric lifting rods 29.

[0040] Through the above structure, the stabilizing telescopic rod 210 enhances the structural stability between the two electric lifting rods 29.

[0041] In this invention, to improve the blackboard's support stability during use, the synchronous motor 25 is activated via the controller 3. The output of the synchronous motor 25 drives the pinion 26 to rotate, which meshes with the large gear 23, thereby driving the bidirectional threaded rod 22 to rotate. Since rectangular sliding sleeves 27 are symmetrically threaded onto the outer sides of both ends of the bidirectional threaded rod 22, its rotation drives the rectangular sliding sleeves 27 on both sides to move towards each other. When the rectangular sliding sleeves 27 on both sides move away, the distance between the two electric lifting rods 29 at the bottom increases, and the support surface area formed between the four electric lifting rods 29 located under the support plate 1 increases, improving support stability and enhancing the blackboard's anti-tipping performance. Conversely, if a smaller support system is needed for storage, the synchronous motor 25 can be controlled to rotate in the opposite direction, bringing the rectangular sliding sleeves 27 closer together and reducing the support surface area. The controller 3 can control the extension and retraction of the electric lifting rods 29 according to the needs of teachers of different heights and diverse teaching scenarios. The extension or retraction of the output end of the electric lifting rod 29 drives the turntable 211 and roller 212 to rise or fall, thereby achieving flexible adjustment of the overall height of the blackboard. During this process, the stabilizing telescopic rod 210, fixedly connected between the outer walls of the two electric lifting rods 29, enhances the structural stability between them, ensuring smooth height adjustment. Once the blackboard is moved to the appropriate position and the support area and height are adjusted, to prevent instability of the roller 212 during static support, the hydraulic rod 72 can be activated via the controller 3. The hydraulic rod 72 drives the sliding sleeve 71 to slide downwards on the outer wall of the output end of the electric lifting rod 29, causing the cover 74 to abut against the ground. The rubber gasket 75 fixedly installed at the bottom of the cover 74 increases friction with the ground, providing stable support and effectively enhancing the blackboard's static support stability.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
