Description

Technical Field

[0001] This utility model relates to the field of intelligent educational equipment technology, and in particular to an interactive device for group collaborative learning. Background Technology

[0002] In modern education, collaborative learning in small groups has become an important teaching model for enhancing student participation and cultivating teamwork skills. However, the desks commonly used in classrooms currently have the following significant shortcomings: 1. Most existing desks are one-piece rectangular structures, which cannot be quickly reshaped. When group discussions are needed, it is inconvenient to piece them together, and the resulting layout is often irregular and unstable, affecting the effectiveness of collaboration.

[0003] 2. Some desks with electronic displays typically have fixed screens that cannot be adjusted, leading to glare or poor viewing angles for students of different heights or those viewing from the side. Furthermore, multi-screen interaction often relies on wired connections. This not only results in cluttered cables and safety hazards in the classroom but also makes plugging and unplugging interfaces cumbersome and prone to failure due to damaged interfaces or poor contact.

[0004] Therefore, there is an urgent need in this field for a comprehensive solution that integrates flexible physical form, optimized human-computer interaction experience, and wireless intelligent collaboration. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an interactive device for collaborative learning in groups. This device can quickly adapt to both independent learning and group collaboration scenarios through its own deformation, providing a comfortable viewing angle and enabling wireless interaction, effectively solving many of the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an interactive device for group collaborative learning, including a main table, at least one side of the main table is connected to an expandable wing plate through a rotating connection mechanism, a support locking mechanism is provided between the main table and the wing plate to provide support and maintain stability when the wing plate is expanded to the use position, and a docking positioning mechanism is provided on the edge of the wing plate for docking with other interactive devices. The main table is equipped with an interactive display unit and a built-in power supply unit, which contains a main control unit and a wireless communication unit. The interactive display unit is movably mounted on the main table via an angle adjustment mechanism. The wireless communication unit supports self-organizing network communication protocols, and the main control unit is configured to work collaboratively with other interactive devices.

[0007] As a further description of the above technical solution: The rotating connection mechanism is a concealed hinge with an opening angle of 180°.

[0008] As a further description of the above technical solution: The support and locking mechanism includes a magnetic block, a magnetic plate, and a pin structure. The magnetic block is fixed to the lower surface of the wing plate in the unfolded state, and the magnetic plate is fixed to the lower surface of the main table body. When the wing plate is folded, the magnetic block and the magnetic plate are attracted to each other.

[0009] As a further description of the above technical solution: The pin structure is embedded in the lower surface of the main table body and includes a housing and a movable pin. The wing plate has a socket on one side that matches the movable pin.

[0010] As a further description of the above technical solution: The docking and positioning mechanism includes male and female connectors respectively located on the two pairs of wing plate joint edges of the main table body. Both male and female connectors are made of magnetic material and can be magnetically connected to each other.

[0011] As a further description of the above technical solution: The angle adjustment mechanism includes a damping hinge assembly disposed on one side of the interactive display unit. One end of the damping hinge assembly is connected to the interactive display unit, and the other end is mounted on the main table.

[0012] As a further description of the above technical solution: The angle adjustment mechanism also includes an adjustment component located on the other side of the interactive display unit. The adjustment component consists of a rotating rod, a rotating sleeve, and a locking bolt. The rotating rod is installed on one side of the interactive display unit. The rotating sleeve is fitted onto the outer surface of the rotating rod and connected to the main table body. The locking bolt is threadedly connected to the rotating sleeve and is used to press against the rotating rod to achieve fixation.

[0013] As a further description of the above technical solution: The main table is also equipped with an audio acquisition unit and an identity recognition unit.

[0014] This utility model has the following beneficial effects: This invention allows for a simple folding and assembly process, transforming an individual desk into a circular collaborative table. This solves the problems of irregular and unstable layouts in traditional desks, adapting to the need for rapid switching in teaching scenarios. The support and locking mechanism, employing both magnetic and pin locking, along with a docking and positioning mechanism using male and female connectors, ensures structural rigidity and stability in various usage configurations, overcoming the instability inherent in simple assembly. The adjustable angle design of the interactive display unit effectively avoids glare and viewing angle issues associated with fixed screens, providing comfortable viewing conditions for all participants and enhancing the equality and participation in collaboration. Wireless communication enables the connection of multiple interactive devices, completely eliminating cumbersome wired connections and solving the problems of messy cables and easily damaged interfaces. This achieves a convenient "assemble and use" effect, demonstrating strong practicality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 One embodiment of this utility model is provided: The main body of the interactive device of this utility model is a rectangular main table 1. The left and right sides of the main table 1 are connected to fan-shaped wing plates 2 by concealed cross hinges. The hinges have an opening and closing degree of 180°, which allows the wing plates 2 to switch between a retracted state that is close to the side of the main table 1 and a horizontally unfolded state.

[0024] The implementation method of the supporting locking mechanism 4 is as follows Figure 3 As shown: A magnetic block 41 is fixed on the lower surface of the wing plate 2, and a magnetic piece 42 is fixed at the corresponding position on the lower surface of the main table body 1. When the wing plate 2 is rotated in the folding direction to a near horizontal position, the magnetic block 41 and the magnetic piece 42 are attracted to each other, which helps the wing plate 2 to be initially positioned and kept in the folded state. When the wing plate 2 is fully unfolded to the horizontal position, the pre-set insertion hole 21 at the root of the wing plate 2 is exactly aligned with the movable pin. Pushing the pin can insert it into the insertion hole 21 to achieve mechanical locking and ensure that the wing plate 2 will not be accidentally folded when bearing weight.

[0025] The implementation method of docking positioning mechanism is as follows Figure 1 , Figure 3 and Figure 6 As shown: When the edges of the wing plates 2 of the two devices are close together, the male connector 6 is inserted into the female connector 5 to magnetically engage and complete the splicing.

[0026] The implementation method of angle adjustment mechanism 8 is as follows Figure 1 and Figure 5 As shown: The interactive display unit 10 is a touchscreen, connected to the main table body 1 on one side via a damping pivot assembly 81. Users can apply a certain force manually to infinitely adjust the screen's tilt angle. The adjustment assembly consists of a rotating rod, a rotating sleeve, and a locking bolt 82. The rotating rod is installed on one side of the interactive display unit 10, the rotating sleeve is fitted onto the outer surface of the rotating rod and connected to the main table body 1, and the locking bolt 82 is threadedly connected to the rotating sleeve to secure the rotating rod. This allows for precise screen angle positioning and prevents the screen from changing angle due to gravity. When not in use, it can be rotated to a horizontal position to function as a writing tablet.

[0027] The main control unit 11 uses an embedded processor based on the ARM Cortex-A series core. This processor integrates a multi-core CPU, GPU, video codec, and rich peripheral interfaces, serving as the control and data processing center of the entire system. The built-in power supply unit 13 uses a lithium polymer battery pack and is equipped with a battery management system (BMS). The output of the BMS is connected to the power management chip of the main control unit via a DC power line, and the chip provides the necessary stable voltages of 3.3V, 5V, and 12V to each unit in the system. The interactive display unit 10 uses a 10.1-inch IPS fully laminated touch screen. The touch function is connected to the main control unit 11 via a USB interface or an I2C interface. The wireless communication unit 12 uses a module that supports Bluetooth 5.0 and above and is compatible with the Mesh network protocol. This module interacts with the main control unit (11) for data and command communication via a UART serial port or an SDIO interface. The audio acquisition unit 9 uses a four-microphone linear array, and its interface is directly connected to the I2S input interface of the main control unit 11. The identification unit 7 uses a reader chip based on the NFC Forum Type 2 / 4 tag protocol to read student card or device ID information.

[0028] When group collaboration is required, the user unfolds the wing plate 2 and locks it with the pin, pushes multiple devices closer together, and assembles them into a ring through the male connector 6 and the female connector 5 (e.g., Figure 5 The empty space allows people to easily pass through and enter the group to display and interact.

[0029] When multiple interactive devices are assembled through the docking and positioning mechanism, the physical distance between any two adjacent devices is mechanically limited to the effective range of Bluetooth communication. Upon detecting a sufficiently strong signal from a device of the same type, the wireless communication unit 12 automatically initiates and completes network formation according to its embedded standard Bluetooth Mesh networking procedure. No algorithmic intervention is required from this invention.

[0030] Once the network is established, a master device is required. This can be achieved through a simple, deterministic hardware logic, such as pre-setting a rule in the firmware of the main control unit 11—the device with the smallest Bluetooth MAC address in the entire network automatically becomes the master device. The MAC address is a unique hardware identifier for the device, and this rule ensures the uniqueness and simplicity of determining the master-slave relationship.

[0031] Once the master device is determined, its master control unit 11 undertakes the coordination task, sending the display content of the local interactive display unit 10 to the slave devices via the data publish / subscribe mechanism of the Bluetooth Mesh network. After receiving the data, the slave device's master control unit 11 drives its local screen to display the same content, achieving synchronization.

[0032] In summary, the intelligent networking function of this utility model is achieved by utilizing the change in physical distance between devices caused by the mechanical assembly action, which in turn leads to a significant change in the physical quantity of wireless signal strength (RSSI), thereby triggering the standard Bluetooth Mesh protocol stack to execute its inherent networking program. It is a typical embodiment combining hardware structure and communication protocol, fully complies with the protection requirements of a utility model patent, and has been fully disclosed.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
