Description

Technical Field

[0001] This utility model relates to the field of electronic sand table technology, and in particular to an electronic sand table with a physical object recognition and interaction system. Background Technology

[0002] The physical object recognition interactive system electronic sand table is an intelligent interactive platform that integrates physical models and digital technology. It uses built-in sensors or image recognition technology to capture physical models (such as buildings, vehicles, etc.) placed on the sand table in real time, and links them with virtual projection or screen display to show dynamic data, three-dimensional scenes and related information.

[0003] Users can interact with the sand table via gestures, touch, or mobile devices to achieve functions such as spatial layout simulation, scheme deduction, and data visualization analysis. The system supports multi-user collaborative operation and can dynamically overlay geographic information, IoT data, and simulation models, making it suitable for fields such as urban planning, military exercises, and educational training. Its advantages lie in its intuitive display that blends virtual and real elements, its instant interactive experience, and its cross-platform data integration capabilities, effectively improving decision-making efficiency and scenario-based understanding, and providing innovative solutions for complex system demonstrations and collaboration.

[0004] Existing electronic sand tables work by embedding an identification token at the bottom of the corresponding physical model. When the physical model is placed on the electronic sand table, the electronic sand table recognizes the identification token at the bottom of the physical model and begins to introduce relevant information about the physical model. One electronic sand table can recognize multiple physical models. In actual use, most of the physical models are placed in the storage cabinet at the bottom of the electronic sand table. However, when recognizing and introducing multiple physical models, it is necessary to constantly put the physical models in or take them out of the storage cabinet, which is quite inconvenient. On the other hand, piling up multiple physical models at the edge of the electronic sand table will affect the customer's view of the electronic sand table. Utility Model Content

[0005] The purpose of this invention is to provide an electronic sand table for physical object recognition and interaction system to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electronic sand table for physical object recognition and interaction system, comprising an electronic sand table body, a storage cabinet fixedly installed at the bottom of the electronic sand table, a support plate provided on the side wall of the storage cabinet, a lifting mechanism provided between the two ends of the support plate and the side wall of the storage cabinet, and a limit mechanism provided between the bottom of the support plate and the side wall of the storage cabinet.

[0007] As a further description of the above technical solution: the lifting mechanism includes two fixed blocks, which are fixedly installed on the bottom of the electronic sand table body. A swing arm is rotatably installed on each of the two fixed blocks, and the end of the two swing arms away from the fixed blocks is rotatably connected to both ends of the support plate.

[0008] As a further description of the above technical solution: the limiting mechanism includes a slide block, which is slidably installed on the side wall of the storage cabinet. A limiting plate is provided on the slide block, and a connecting block is fixedly installed at the bottom of the support plate. The connecting block is slidably installed on the limiting plate.

[0009] As a further description of the above technical solution: a connecting rod is fixedly installed on the side wall of the slide block, the limiting plate is slidably connected to the connecting rod, and the connecting rod is disposed inside the limiting plate.

[0010] As a further description of the above technical solution: support rods are rotatably mounted on the side walls of the two swing arms, and sliders are rotatably connected to the ends of the two support rods away from the swing arms. The two sliders are slidably mounted on the side walls of the storage cabinet. Pins are slidably mounted on both sides of one side of the storage cabinet. A spring is fixedly connected between the pins and the storage cabinet, and the pins are engaged with the side walls of the sliders.

[0011] As a further description of the above technical solution: a door panel is rotatably installed on the side wall of the storage cabinet, and casters are fixedly installed at the four corners of the bottom of the storage cabinet.

[0012] This invention provides an electronic sand table for interactive physical object recognition. It offers the following advantages: During use, to facilitate quick retrieval of physical models, a support plate is installed on the side wall of the storage cabinet. The support plate has two states: a folded state, in which the support plate is close to the side wall of the storage cabinet and located at the bottom edge of the electronic sand table body; and an unfolded state, in which the support plate is away from the side wall of the storage cabinet and raised to one side of the electronic sand table body. During the transition between these two states, the support plate, under the action of a limiting mechanism, always faces vertically upwards. Therefore, placing the physical model on the support plate facilitates retrieval. Furthermore, in the folded state, the support plate's position at the bottom edge of the electronic sand table body prevents excessive length extension, reducing the risk of the physical model falling off the support plate due to collision.

[0026] 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.

[0027] Reference Figure 1-9An electronic sand table for physical object recognition interaction system includes an electronic sand table body 1, a storage cabinet 2 fixedly installed at the bottom of the electronic sand table, a support plate 3 provided on the side wall of the storage cabinet 2, lifting mechanisms provided between the two ends of the support plate 3 and the side wall of the storage cabinet 2, and a limiting mechanism provided between the bottom of the support plate 3 and the side wall of the storage cabinet 2. In the use of this device, to facilitate quick retrieval of physical models, the support plate 3 is provided on the side wall of the storage cabinet 2. The support plate 3 has two states: a retracted state and a folded state. Located near the side wall of the storage cabinet 2 and at the bottom edge of the electronic sand table body 1, the support plate 3 is away from the side wall of the storage cabinet 2 in the unfolded state and is raised to one side of the electronic sand table body 1. During the transition between the two states, the support plate 3 is always facing vertically upward under the action of the limiting mechanism. Therefore, it is convenient to place the physical model on the support plate 3 to retrieve the physical model. In the retracted state, the support plate 3 is located at the bottom edge of the electronic sand table body 1, which will not cause additional length overextension in this state and reduce the risk of the physical model on the support plate 3 being knocked off.

[0028] As a preferred technical solution of this embodiment, the lifting mechanism includes two fixed blocks 4, which are fixedly installed at the bottom of the electronic sand table body 1. Each of the two fixed blocks 4 is rotatably mounted with a swing arm 5. The end of each swing arm 5 away from the fixed block 4 is rotatably connected to both ends of the support plate 3. When it is necessary to lift the support plate 3, the swing arm 5 is rotated so that the swing arm 5 is horizontal, which can lift the support plate 3.

[0029] As a preferred technical solution in this embodiment, the limiting mechanism includes a slide block 6, which is slidably installed on the side wall of the storage cabinet 2. A limiting plate 7 is provided on the slide block 6. A connecting block 8 is fixedly installed at the bottom of the support plate 3, and the connecting block 8 is slidably installed on the limiting plate 7. During the rotation and rise of the swing arm 5, the support plate 3 rises accordingly. However, since the connecting block 8 fixedly installed at the bottom of the support plate 3 is slidably connected to the limiting plate 7, and the limiting plate 7 is always perpendicular to the side wall of the storage cabinet 2, the support plate 3 always remains vertically upward. At the same time, the slide block 6 slides on the side wall of the storage cabinet 2 to cooperate with the lifting and lowering of the support plate 3.

[0030] As a preferred technical solution in this embodiment, a connecting rod 9 is fixedly installed on the side wall of the slide block 6, and the limiting plate 7 is slidably connected to the connecting rod 9. The connecting rod 9 is disposed inside the limiting plate 7. When the support plate 3 is retracted, the connecting rod 9 is completely inside the limiting plate 7. When the support plate 3 is unfolded, the limiting plate 7 moves along the connecting rod 9 to cooperate with the unfolding of the support plate 3. The connecting block 8 moves on the limiting plate 7. When it moves to the end, the limiting plate 7 slides along the connecting rod 9 again, thereby reducing the length of the limiting plate 7 and preventing the limiting plate 7 from being too long and causing the limiting plate 7 to overextend.

[0031] As a preferred embodiment, support rods 10 are rotatably mounted on the side walls of the two swing arms 5. A slider 11 is rotatably connected to one end of each support rod 10 away from the swing arms 5. The two sliders 11 are slidably mounted on the side walls of the storage cabinet 2. Pins 12 are slidably mounted on both sides of one side of the storage cabinet 2. A spring 13 is fixedly connected between the pins 12 and the storage cabinet 2. The pins 12 engage with the side walls of the sliders 11. When the support plate 3 rises to the top, the pins 12 engage with the sliders 11 to lock them in place. At this time, the support rods 10 and swing arms 5 provide support, stabilizing the support plate 3. When the support plate 3 is retracted, the pins 12 are pulled out, allowing the pins 12 to lock into contact with the sliders 11.

[0032] As a preferred technical solution in this embodiment, a door panel 14 is rotatably installed on the side wall of the storage cabinet 2, and universal wheels 15 are fixedly installed at the four corners of the bottom of the storage cabinet 2; the door panel 14 seals the internal space of the storage cabinet 2 to protect the physical model, and the universal wheels 15 facilitate the overall movement of the device.

[0033] The general working principle of this utility model is as follows:

[0034] The electronic sand table body 1 is equipped with multiple recognition tokens. Object recognition is based on capacitive touch screen tag recognition technology, which is implemented by object recognition tokens combined with underlying recognition software. It supports the simultaneous recognition of multiple tokens. The tokens are embedded or glued to the bottom of the model to be recognized. When the token touches the touch screen, the program recognizes the model's ID, coordinates and angle information, and sends a TUIO message to the application, which pops up an introduction about the model.

[0035] To facilitate the retrieval of physical models, multiple physical models to be used are placed on the support plate. When in use, the swing arm is rotated to raise the support plate, making it easy to retrieve the physical models. At the same time, when the support plate is raised, it remains horizontal and stable due to the restriction plate. When retracted, the support plate is located at the bottom edge of the electronic sand table body, which will not cause additional length overextension in this state, reducing the risk of physical models being knocked off the support plate.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
