[0002] Building blocks, as a classic interlocking toy, are beloved by children and adults alike for their high degree of freedom and creativity. Traditional building block toys typically consist of a series of standardized plastic blocks that users can freely assemble into various static models, such as houses, vehicles, and animals, using the protrusions (tenons) and grooves (mortises). This type of play primarily develops users' manual dexterity, spatial imagination, and structural awareness. However, existing building block toys suffer from the following shortcomings: First, they generally lack voice interaction capabilities, unable to understand or respond to user voice commands, and unable to engage in dialogue, significantly diminishing their fun and immersive experience. Second, their level of intelligence is limited; they typically operate as a closed system, making it difficult to communicate with other smart devices or networks, and thus unable to acquire external information or achieve more complex remote control functions.

[0021] This invention proposes a building block robot, aiming to solve the technical problem of how to improve the functionality of building block robots.

[0022] In the embodiments of this utility model, such as Figure 1 As shown, the building block robot includes: a head 10, which has a mounting cavity 11, and at least one side wall of the head 10 has a connecting post 12 for detachable connection with other building blocks; a main control board, which is mounted in the mounting cavity 11; a voice interaction module, which is mounted in the mounting cavity 11 and electrically connected to the main control board; a communication module, which is mounted in the mounting cavity 11 and electrically connected to the main control board, and is used to send or receive communication signals; a battery, which is mounted in the mounting cavity 11 and electrically connected to the main control board; and a body 20, which is detachably assembled from the head 10, and is composed of multiple assembled building blocks.

[0023] In this embodiment, the mounting cavity 11 refers to a closed space for accommodating the main control board, voice interaction module, communication module, and battery. Specifically, it can be implemented using an injection-molded hollow cube structure. The mounting cavity 11 encapsulates the electronic components into independent functional units, protecting the internal components while maintaining the block-like shape. At least one sidewall of the head 10 is provided with a connecting post 12, which is a structure for mortise and tenon connection with conventional building blocks. Specifically, it can be implemented using a raised cylinder or a square column. By standardizing the dimensions of the connecting post 12 to match the grooves in traditional building blocks, physical compatibility between the intelligent module and traditional building blocks is achieved.

[0024] The main control board, serving as the core control circuit board, can be implemented using an embedded microcontroller. It coordinates the operation of the voice interaction module and the communication module through integrated data processing capabilities. The voice interaction module is the hardware component that enables voice input and output functions. It can be implemented using a microphone array and speaker combination, processing user commands and generating voice feedback through a voice recognition algorithm. The communication module is the hardware unit that enables wireless communication. It can be implemented using a Wi-Fi module or a Bluetooth module, establishing a data interaction channel with external devices or networks via wireless protocols. The battery is an independent power supply unit, specifically a rechargeable lithium polymer battery, ensuring continuous operation of the intelligent module when it is disconnected from external power. The body 20 adopts a traditional modular mechanical structure. Specifically, it can be formed by stacking standard building blocks to create the torso 21 and limbs. The head 10 is detachably connected, allowing for free combination of the intelligent module and the mechanical structure.

[0025] The voice interaction module, communication module, and main control board are integrated into the head 10 module in the form of building blocks. The standardized connecting column 12 achieves physical compatibility between the intelligent module and traditional building blocks. At the same time, the detachable splicing structure allows the intelligent head 10 module to be used as an independent functional unit and combined with any building blocks. While retaining the free assembly characteristics of building blocks, it endows the robot with voice interaction, network communication and autonomous operation capabilities.

[0026] The head unit 10, as an independent functional unit, integrates the main control board, voice interaction module, communication module, and battery. This centralized packaging design maintains the modular form while achieving the integration of the electronic system. The connecting pillar 12 enables the intelligent head unit 10 module to be compatible with conventional building blocks, achieving interoperability between the intelligent module and ordinary building blocks.

[0027] The main control board coordinates the work of the voice interaction module and the communication module. When the user issues a voice command, the voice interaction module receives and processes the command, then transmits it to the main control board. The main control board controls the robot's behavior or response based on the command. The communication module is responsible for exchanging data with external devices or networks, expanding the robot's functional range.

[0028] The battery provides independent power to the entire system, ensuring the robot can operate continuously without being limited by an external power source. The body 20 adopts a modular structure, allowing users to freely assemble robot bodies of different shapes as needed. The detachable and modular design of the head 10 and body 20 enables flexible combination of intelligent modules and mechanical structures.

[0029] Users can interact with the robot via voice commands, such as asking questions or issuing control commands. The robot responds to the user by answering with voice or performing corresponding actions. Simultaneously, the communication module can connect to a smartphone or home network to achieve remote control or data synchronization. This design, combining modular integration with the modularity of building blocks, constructs a scalable robot system with intelligent interactive capabilities. It retains the assembly freedom of traditional building blocks while introducing voice interaction and communication functions, greatly enhancing the intelligence and fun of building block toys.

[0030] Through the above solution, this application solves the problems of traditional building block toys lacking voice interaction capabilities, insufficient intelligence, and inability to communicate with other smart devices. The voice interaction module integrated into the head 10 enables the robot to understand and respond to voice commands, achieving human-machine dialogue and greatly enhancing the toy's fun and interactivity. The introduction of the communication module allows the building block robot to exchange data with other smart devices or networks, expanding its functional range and enabling advanced functions such as remote control and information retrieval. Simultaneously, the modular design retains the modularity of building blocks, allowing users to freely assemble robots of different shapes, stimulating creativity. Furthermore, an independent battery power system ensures the robot's mobility and ease of use.

[0031] For example, such as Figure 2 As shown, the head 10 includes a main body 13 and an interactive panel 14. The main body 13 is provided with an installation port. The interactive panel 14 is connected to the main body 13 and covers the installation port. The interactive panel 14 and the main body 13 surround each other to form the installation cavity 11.

[0032] The mounting port of the main body 13 provides ample operating space for the electronic components. The interaction panel 14 is connected to the main body 13 via a snap-fit ​​structure, which includes a slot 135 on the inner wall of the main body 13 and a protrusion 146 on the back of the interaction panel 14. The mounting port is located on the front side of the main body 13, allowing the main control board to be inserted vertically into the mounting cavity 11. The interaction panel 14 is detachably connected to the main body 13 via the elastic deformation of the protrusion 146 and the slot 135.

[0033] The above technical solution achieves a modular design for the head 10 structure, simplifying the installation and maintenance of electronic components. The mounting port of the main body 13 provides an open assembly entrance, facilitating the positioning and fixing of each module. The detachable connection design between the interaction panel 14 and the main body 13 allows for quick access to internal components by simply removing the interaction panel 14 during maintenance, avoiding the complexity of disassembling the entire structure. Simultaneously, the fit between the interaction panel 14 and the main body 13 enhances the stability and sealing of the head 10 structure, providing excellent physical protection for the electronic modules. This split structure optimizes the construction of the mounting cavity 11, ensuring the integrity of the internal space while improving the protection performance of electronic components, effectively supporting the long-term stable operation of the modular robot.

[0034] For example, such as Figure 2 As shown, the interactive panel 14 is provided with at least one of a display screen 141, control buttons 142, a microphone hole 143, and a sound outlet 144.

[0035] The display screen 141 can be embedded in the upper area of ​​the interactive panel 14 to display graphics and text. Control buttons 142 can be located below the display screen 141, using a physical press or touch-sensitive design, such as a combination of a power button and a toggle button. The aperture of the microphone 143 can range from 0.5 to 1.2 mm, arranged in an array to optimize sound wave acquisition. The sound output holes 144 can be symmetrically distributed on both sides of the panel, enhancing audio output through acoustic cavity design. When the interactive panel 14 and the head 10 body 13 form a mounting cavity 11, the microphone 143 and the microphone array within the mounting cavity 11 form a sound guiding channel, the sound output holes 144 and the speaker module form a resonant cavity, and the control buttons 142 form a command transmission link with the main control board through conductive contacts. A high-sensitivity microphone is installed inside the microphone 143 to collect user voice commands. A small speaker is installed inside the sound output holes 144 to play the robot's voice feedback and prompts.

[0036] During user operation, the display screen 141 is configured to display real-time battery status, connection status, or interactive menus, for example, by updating the interface content via the main control board driving the display module. When the user presses the control button 142, a trigger signal is transmitted to the main control board via conductive contacts, thereby controlling the robot to perform movement, vocalization, or communication operations. Voice commands enter the mounting cavity 11 through the microphone hole 143, are collected by the microphone array, and transmitted to the voice interaction module for processing. The processing result can be played back as feedback voice through the speaker and the sound outlet 144. In a simplified embodiment, with only the microphone hole 143 and the sound outlet 144 provided, the voice interaction module achieves bidirectional communication through the sound wave conduction path; when the display screen 141 and control button 142 are added, the interaction panel 14 forms a composite control interface, improving operational efficiency through multimodal input and output. Thus, while maintaining structural enclosure, the interaction panel 14, through its design containing at least one interactive element, satisfies basic voice interaction needs and can achieve complex control functions through modular expansion, effectively solving the technical shortcomings of the single interaction method in traditional block robots.

[0037] The above technical solutions diversify the interaction methods of the building block robot. The display screen 141 provides intuitive visual feedback, allowing users to clearly understand the robot's working status and interactive content. Control buttons 142 allow users to perform quick physical operations, enabling direct control of the robot. The microphone 143 and speaker 144 enable the robot to have voice interaction capabilities; users can control the robot through voice commands, and the robot can also converse with users through voice feedback. This diversified interactive design greatly enhances the intelligence and practicality of the building block robot, transforming it from a simple assembly toy into an intelligent companion with rich interactive functions. Therefore, the robot can better meet users' needs in different scenarios, improve user experience and engagement, and also lay the foundation for future functional expansion.

[0038] For example, such as Figure 2 and Figure 3 As shown, the head 10 is cube-shaped or cuboid-shaped, and the connecting posts 12 are provided on all five side walls of the main body 13. The geometry of the head 10 is defined as cube or cuboid, and the connecting posts 12 are evenly distributed on the five side walls excluding the side wall where the interaction panel 14 is located. The diameter of the connecting posts 12 can be between 3 mm and 8 mm, for example, 5 mm, and the height can be between 4 mm and 12 mm, for example, 8 mm.

[0039] The regular geometric shape of the cube or cuboid allows the six side walls to form standardized connection planes, five of which are configured as functional connection surfaces. Each functional connection surface has a connecting post 12 that interlocks with the grooves of adjacent blocks. When the head 10 rotates 90 degrees or 180 degrees, at least three of the side wall connecting posts 12 can effectively connect with the body 20 blocks. During assembly, the connecting posts 12 on the top side wall allow for vertical stacking of blocks, the connecting posts 12 on the two side walls support horizontal expansion structures, and the connecting posts 12 on the back side wall can connect to auxiliary functional modules.

[0040] The above technical solution solves the problems of directional compatibility and structural stability when the head 10 is assembled with other building blocks. The head 10 adopts a cube shape, giving its sidewalls symmetry and standardized features, facilitating multi-directional matching with other building blocks and expanding the degrees of freedom in assembly. Connecting posts 12 are set on all five sidewalls of the main body 13, increasing the density and distribution range of connection points, improving the connection strength between the head 10 and the body 20, and allowing users to expand the additional building block structure in multiple dimensions. This design, through the synergistic optimization of geometric constraints and connection point layout, strengthens the function of the head 10 as a core connecting node in the building block robot, improving the overall structural flexibility and stability.

[0041] For example, such as Figure 3 As shown, the main body 13 has a first sidewall 131 adjacent to the interactive panel 14. The first sidewall 131 is provided with a foolproof structure 132. The first sidewall 131 is used as a bottom reference surface during the assembly process of the head 10.

[0042] The foolproof structure 132 is configured as a physical protrusion with tactile and visual recognition features, and its height can range from 0.5 mm to 2 mm, providing a distinct tactile feel without affecting the flatness of the splicing. The adjacent positional relationship between the first sidewall 131 and the interaction panel 14 is defined as forming a right angle or obtuse angle connection between them. The shape of the foolproof structure 132 may include stripes, dot matrix, or asymmetrical geometric patterns, such as using border-shaped protrusions to distinguish it from the smooth surfaces of other sidewalls.

[0043] During assembly, the user confirms the position of the reference surface by touching the foolproof structure 132 on the first sidewall 131, and aligns the reference surface with the body 20 for docking. The protrusion of the foolproof structure 132 prevents other sidewalls from being mistaken for the reference surface, ensuring that the head 10 can only be installed in the correct direction. The adjacency between the reference surface and the interaction panel 14 ensures that the display screen 141 or buttons always face a preset orientation; for example, when the interaction panel 14 faces forward, the reference surface is at the bottom, preventing functional components from being inverted after installation. The synergistic effect of the foolproof structure 132 and the connecting post 12 enhances the stability of the assembly; for example, the reference surface connecting post 12 and the corresponding interface of the body 20 form a unique match, preventing loosening of the connection due to incorrect orientation. Thus, the physical identification of the reference surface and the orientation of the functional components form a dual constraint, eliminating orientation confusion and improving structural reliability.

[0044] The above technical solution solves the problem of confusion in the assembly direction of the symmetrical head 10. By protruding a foolproof structure 132 on the first sidewall 131, an asymmetrical physical marker is formed, forcing this sidewall to become the bottom reference surface during assembly. Users can perceive the position of this reference surface by touch, avoiding mistaking other sidewalls for the bottom. The reference surface is positioned adjacent to the interaction panel 14, ensuring that the interaction panel 14 is always in the preset position after the head 10 is installed, making the positions of the display screen 141, buttons, and other functional components conform to ergonomic design. Through the dual positioning mechanism of the reference surface and the foolproof structure 132, the uniqueness of the orientation of the head 10 when assembling with other building blocks is guaranteed, improving the stability of the overall structure. Furthermore, when assembling electronic components, using the first sidewall 131 as the bottom reference surface ensures the accurate positioning of the electronic components during assembly, thereby improving assembly efficiency.

[0045] For example, such as Figure 4 As shown, the inner wall of the main body 13 is provided with a slot 135, and the interactive panel 14 is provided with a connecting plate 145 protruding on the side facing the main body 13. The connecting plate 145 is provided with a snap-fit ​​protrusion 146, which engages with the slot 135.

[0046] The slot 135 can be located on the top, bottom, or side of the inner wall of the main body 13, with a depth ranging from 1 to 3 mm and a width that forms a clearance fit with the protrusion 146. The protrusion height of the connecting plate 145 can be set to 2 to 5 mm, and it is made of plastic material integrally molded with the interactive panel 14. The protrusion 146 can be designed with a trapezoidal cross-section, with its top width being smaller than the opening width of the slot 135 to facilitate insertion. The matching relationship between the slot 135 and the protrusion 146 achieves precise positioning by limiting lateral displacement. At the same time, the protruding structure of the connecting plate 145 makes the protrusion 146 and the slot 135 form a vertical contact surface, preventing tilting due to external forces. When the main body 13 and the interactive panel 14 are assembled, the protrusion 146 supported by the connecting plate 145 slides along the guide of the slot 135 until it undergoes elastic deformation and then engages in the locking position. At this time, the inner wall of the slot 135 provides three-point support for the protrusion 146, ensuring longitudinal tensile strength and lateral torsional strength.

[0047] During assembly, the protruding portion of the connecting plate 145 first contacts the inner wall of the main body 13, and is pre-positioned by the inclined surface of the opening edge of the latching protrusion 146 and the latching groove 135. When pressure is applied, the elastic deformation of the latching protrusion 146 causes it to slide into the latching groove 135. At this time, the side wall of the latching groove 135 contacts the plane of the side of the latching protrusion 146 to form a lateral limit, and the top wall of the latching groove 135 and the barb structure on the top of the latching protrusion 146 form a longitudinal lock. The snap-fit ​​engagement method avoids the tooling required for screw fixing while maintaining structural strength.

[0048] The above technical solution achieves a stable connection between the interactive panel 14 and the main body 13. The snap-fit ​​between the protrusion 146 and the slot 135 provides precise positioning, preventing panel offset or misalignment. The protruding design of the connecting plate 145 increases the contact area and enhances the overall structural strength. The snap-fit ​​structure ensures assembly stability while facilitating disassembly, allowing for tool-free installation and removal, thus improving assembly efficiency.

[0049] For example, such as Figure 3 As shown, the main body 13 has a second sidewall 133 disposed opposite to the interactive panel 14, and the second sidewall 133 has heat dissipation holes 134.

[0050] The positioning of the second sidewall 133 is based on the cubic or cuboid structural features of the head 10. Its distance from the interaction panel 14 allows the heat dissipation holes 134 to be distributed on the non-functional sidewall. The diameter of the heat dissipation holes 134 can be set to 1-3 mm, and the hole spacing is 2-5 times the hole diameter, for example, using a honeycomb or grid arrangement, with the opening area accounting for 10%-30% of the sidewall area. The connecting posts 12 of this sidewall are staggered from the positions of the heat dissipation holes 134 to ensure that the splicing function is not affected. By limiting the heat dissipation holes 134 to exist only on the second sidewall 133, a unidirectional heat dissipation path is formed, avoiding the reduction in structural strength caused by multiple openings.

[0051] Heat generated by the internal electronic components is dissipated outwards through air convection via the heat dissipation holes 134. Since the second sidewall 133 is far from the display screen 141 and microphone hole 143 of the interaction panel 14, the airflow does not interfere with the sound wave transmission of the voice interaction module. The location of the heat dissipation holes 134 corresponds to the heat-generating areas of the electronic components within the main body 13; for example, the main control board faces the center of the heat dissipation hole 134, and the battery is located at the edge of the heat dissipation hole 134, thus achieving differentiated heat dissipation efficiency. This design achieves efficient heat dissipation through localized openings on a single sidewall while maintaining the overall size of the head 10, while retaining the layout of the connecting pillars 12 on the five sidewalls to ensure the integrity of the multi-directional splicing function.

[0052] By creating heat dissipation holes 134 on the second sidewall 133 of the main body 13, heat exchange between the internal air of the head 10 and the external environment is effectively promoted. This allows heat generated by electronic components such as the main control board and battery to dissipate promptly, preventing heat accumulation in the enclosed space. This design not only reduces the operating temperature of the electronic components but also improves the operational stability and lifespan of the block robot. Furthermore, since the heat dissipation holes 134 are located on the sidewall away from the interaction panel 14, they do not obstruct or interfere with the interactive function modules, ensuring the normal use of the interactive functions. In addition, this heat dissipation solution ensures effective heat dissipation without affecting the overall assembly function and aesthetic harmony of the head 10, achieving a balance between structural compactness and heat dissipation efficiency.

[0053] For example, such as Figure 1 As shown, the torso 20 includes a torso 21 and two upper limbs 22 and two lower limbs 23 connected to the torso 21. The head 10 is connected to the top of the torso 21. The two upper limbs 22 are respectively connected to the two sides of the torso 21, and the two lower limbs 23 are connected to the bottom of the torso 21. The torso 21, upper limbs 22, and lower limbs 23 are all assembled from multiple building blocks. The torso 21 is constructed as a cuboid frame structure with a top, bottom, and two sides. The top has a positioning boss corresponding to the bottom surface of the head 10. The top of the torso 21 and the bottom surface of the head 10 form a reference alignment. The modules of the torso 21, upper limbs 22, and lower limbs 23 can be assembled using building blocks of different sizes.

[0054] For example, such as Figure 1As shown, the lower limb 23 includes a leg 231 extending in the vertical direction and a foot 232 detachably connected to the bottom of the leg 231. The cross-sectional dimension of the foot 232 is larger than that of the leg 231. The torso 20 also includes a supporting base plate 24 and a connecting hip 25. The connecting hip 25 is connected to the bottom of the torso 21. The two legs 231 are detachably connected to the left and right sides of the connecting hip 25. The two feet 232 are detachably connected to the top surface of the supporting base plate 24. The cross-sectional dimension of the supporting base plate 24 is larger than that of the head 10. The legs 231, feet 232 and supporting base plate 24 are all assembled from multiple building blocks.

[0055] The design of the leg 231 extending vertically optimizes its longitudinal load-bearing capacity. The detachable connection between the foot 232 and the leg 231 allows for the replacement of foot 232 modules of different sizes or shapes as needed. The cross-sectional dimension of the foot 232 is larger than that of the leg 231, thereby increasing the contact area with the support surface. The hip joint 25 serves as a transition structure between the torso 21 and the lower limbs 23, and has standardized interfaces on both sides to fix the position of the leg 231 and prevent displacement due to uneven force. The top surface of the support base plate 24 is connected to the foot 232 through a snap-fit ​​or slot structure, and its cross-sectional dimension can be set to 1.2 times the size of the head 10 to form a stable bottom support platform. The leg 231, foot 232, and support base plate 24 adopt a modular assembly method, such as through the interlocking of protrusions and grooves, to ensure the mechanical strength between modules, while allowing users to freely adjust the length of the lower limbs 23 or the shape of the foot 232.

[0056] The legs 231, as the main supporting components, transmit loads to the feet 232 through their vertical extension. The increased cross-sectional size of the feet 232 effectively disperses pressure and reduces localized pressure. The combination of the hip joint 25 and the supporting base plate 24 forms a double-fixation structure: the hip joint 25 symmetrically fixes the two legs 231 to the bottom of the torso 21, and the supporting base plate 24 connects to the feet 232 through its top surface. Together, they restrict the lateral displacement of the lower limbs 23. The cross-sectional size of the supporting base plate 24 is larger than that of the head 10, ensuring that the robot's center of gravity projection is always within the range of the base plate, preventing tipping due to uneven weight distribution in the head 10. In the modular assembly method, the interfaces of each module adopt a uniform specification, such as a 5 mm diameter protrusion with an 8 mm spacing, ensuring compatibility between different modules. When it is necessary to adjust the structure of the lower limbs 23, only the corresponding module needs to be disassembled and replaced with a longer leg 231 or a wider foot 232, without changing the overall connection logic, thus achieving a balance between stability and flexibility.

[0057] Through the above technical solutions, a reliable connection between the lower limbs 23 and the torso 21 and the support base plate 24 is achieved. The detachable design of the feet 232 and legs 231 allows users to adjust the size or shape of the feet 232 according to support needs. The wide bottom surface of the support base plate 24, combined with the increased cross-sectional size of the feet 232, effectively disperses the overall weight of the robot and avoids tipping over due to the shift in the center of gravity. The symmetrical plug-in structure connecting the hips 25 ensures the connection stability between the lower limbs 23 and the torso 21, while retaining the flexibility of modular splicing. Users can freely replace different forms of leg 231 or foot 232 modules to adapt to different scenario requirements.

[0058] For example, such as Figure 1 As shown, the upper limb 22 includes an upper arm block 221, a connecting block 222, an elbow block 223, and a finger block 224. The connecting block 222 is connected to the side wall of the torso 21, and the upper arm block 221 is connected to the upper end of the connecting block 222. The elbow block 223 and the finger block 224 are both connected to the connecting block 222. The elbow block 223 is located between the upper arm block 221 and the finger block 224, and it protrudes laterally from the upper arm block 221 and the finger block 224. The connection between the connecting block 222 and the side wall of the torso 21 can be achieved using a mortise and tenon structure or a magnetic interface. The laterally protruding portion of the elbow block 223 can be designed as a fan shape. The end of the finger block 224 can be configured with three fingers or a pincer-shaped structure. Through the above technical solution, modular assembly of the joints of the upper limb 22 is achieved.
