Description

Technical Field

[0001] This invention relates to the field of educational toys, and more particularly to a multifunctional educational toy with human-computer interaction. Background Technology

[0002] Children's educational building blocks are a type of educational toy that stimulates children's imagination, creativity, and problem-solving abilities through building, combining, and creating. Educational building blocks are usually composed of building blocks of various shapes and colors, and children can create various forms by building different structures. The design of educational building blocks encourages children to use their hands and minds, and cultivates their spatial imagination and hand-eye coordination.

[0003] Currently, children's educational building blocks are typically designed with triangular, semi-circular, or square structures. While these structures can cultivate children's spatial imagination and hand-eye coordination to some extent, the range of shapes they can expand into is limited, and they lack interactivity and scientific rigor. In contrast, molecular structure model building block toys often do not record the assembly process in real time, resulting in a lack of understanding during subsequent molecular structure learning and making it difficult to demonstrate the structure in the educational process.

[0004] Therefore, there is a need to propose a human-computer interactive molecular model educational building block to enhance children's interest in chemistry and increase interactivity and scientific accuracy. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a multifunctional educational toy that allows for human-computer interaction.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a human-computer interactive multifunctional educational toy, comprising: a plurality of spherical bases, a plurality of insertion holes arranged in a circumferential array on each of the spherical bases, and a spherical groove disposed at the center position inside the spherical bases.

[0007] A spherical connector is installed in the spherical groove. The spherical connector has a plurality of slots arranged in a circumferential array, and the position of each slot corresponds to the position of the socket. A connector is provided in each slot. The connector has an interface and the interface is configured with a U-shaped structure. The inner wall of the U-shaped structure is provided with a conductive surface.

[0008] Several spherical bases are connected by connecting pins. Each connecting pin has a symmetrical crimp connector at both ends. The crimp connector is a spindle-shaped structure and is adapted to the interface. The connecting pin is divided into an upper rod, a middle rod, and a lower rod. The upper rod and the lower rod are hollow structures. The lower rod is sleeved inside the middle rod. One end of the upper rod is fixedly connected to the middle rod.

[0009] The middle rod has several symmetrically opened circular holes, and each circular hole has a groove symmetrically arranged on both sides. A tensioning structure is installed in the groove. The upper rod and the lower rod are provided with a lifting structure at the end near the pressure joint.

[0010] In a preferred embodiment of the present invention, the tensioning structure includes: a tensioning rod, limiting springs symmetrically installed at both ends of the tensioning rod, and a tensioning plate disposed on one end of the tensioning rod near the sleeve hole; the limiting springs are fixedly installed on the inner wall of the groove, and one end of the tensioning rod extends through the tensioning plate into the interior of the upper rod, and a tensioning block is disposed at the other end of the tensioning rod.

[0011] In a preferred embodiment of the present invention, the upper rod is provided with a plurality of sleeve holes, and the diameter of each sleeve hole corresponds to the diameter of the tension rod. The diameters of the upper rod and the lower rod correspond to the diameters of the insertion holes.

[0012] In a preferred embodiment of the present invention, the lifting structure includes: a plurality of lifting plates, a lifting groove disposed at one end of each lifting plate, and a connecting rod disposed in the lifting groove; the plurality of lifting plates are installed alternately, and the two ends of the connecting rod pass through the lifting groove and connect to the lifting plates.

[0013] In a preferred embodiment of the present invention, the crimp connector is divided into an inverted V-shaped interface and a positive V-shaped interface. The two ends of the inverted V-shaped interface and the positive V-shaped interface are rotatably connected by a rotating rod. The sides of several lifting plates are in contact with the inner walls of the two ends of the inverted V-shaped interface. A conductive segment is provided on the outer wall of the inverted V-shaped interface.

[0014] In a preferred embodiment of the present invention, a fixing plate is installed on one end of the inverted V-shaped interface near the connecting pin. A long groove is formed on the fixing plate, one end of the connecting rod passes through the long groove, and a lifting rod is fitted on the connecting rod.

[0015] In a preferred embodiment of the present invention, the two ends of the inverted V-shaped interface are rotatably connected to the fixing plate through several rotating shafts, and a connecting block is provided on the fixing plate. The connecting block and the fixing plate are fitted together and installed on one end face of the connecting pin.

[0016] In a preferred embodiment of the present invention, the lifting rod extends through the connecting block into the interior of the upper rod, and an L-shaped rod is connected to the end of the lifting rod away from the connecting block. An elongated hole is provided on the upper rod, and one end of the L-shaped rod extends through the elongated hole to the outside.

[0017] A method for using a multifunctional interactive educational toy, characterized by the following steps:

[0018] S1. Place several spherical bases and several connecting pins on the table, and open the recording panel. The recording panel is equipped with a main control system, which displays the three-dimensional model structure of the spherical bases.

[0019] S2. Open the connector inside the spherical base, pick up the connecting pin, pull the L-shaped rod to retract the crimp connector of the shuttle structure inward, insert the crimp connector into the interface after passing through the socket, at which point the conductive section and the conductive surface are in contact with each other to achieve conductivity;

[0020] S3. After the main control system receives the conductive signal after the crimp connector and the interface come into contact, it then displays the three-dimensional model structure of the connecting pin in the recording panel.

[0021] S4. Based on the lengths of the chemical bonds in the molecular model, adjust the length of the connecting pin between the upper and lower rods by aligning the tension rod with the corresponding hole on the upper rod.

[0022] S5. After changing the length of the connecting pin, pull the L-shaped rod again to insert the crimp connector into the interface on the next spherical base to achieve conductivity. The main control system continues to record the model structure until all the assembled molecular structure models are recorded.

[0023] In a preferred embodiment of the present invention, positioners are installed at both ends of the connecting pin in step S4 to locate the length of the connecting pin, and the positioners are wirelessly connected to the main control system.

[0024] This invention addresses the shortcomings of the prior art and has the following beneficial effects:

[0025] (1) This invention proposes a multi-functional educational toy with human-computer interaction. The main control system displays the three-dimensional model structure of the spherical base. Then, the spherical base and the connecting pin cooperate with each other. The crimp connectors at both ends of the connecting pin are adapted to the interface in the spherical base. Conductivity is achieved through the contact between the guide section and the guide surface. After the main control system receives the conductive signal after the crimp connector and the interface are in contact, it displays the three-dimensional model structure of the connecting pin in the recording panel. The connector in the next spherical base is connected to the other end of the connecting pin. The main control system continues to record the model structure until all the assembled molecular structure models are recorded. This structure records the molecular structure model through human-computer interaction, which solves the problem of difficulty in structural display in the subsequent molecular structure learning process due to the lack of a certain understanding process. At the same time, it also improves children's interest in learning chemical molecular structures to a certain extent, increases the interaction between parents and children, and can help children consolidate the chemical knowledge they have learned.

[0026] (2) In this invention, by pulling the L-shaped rod upward, the connecting rod moves in the long slot and the lifting slot. At the same time, the two ends of the inverted V interface and the positive V interface are connected by the rotating rod. The lifting rod moves upward and drives it to rotate on the rotating rod. The crimping joint of the shuttle structure extends and retracts inward, narrowing the width of the crimping joint, and then inserts it into the interface. The guide surface and the guide section inside the interface contact each other to conduct electricity. The crimping joint of the shuttle structure is connected to the U-shaped structure inside the interface to ensure the stable connection of the two components. At the same time, when heat is generated during long-term connection, the heat dissipation effect obtained by the crimping joint of the shuttle structure is better than that of the magnetic suction structure with surface contact connection.

[0027] (3) By pulling the tension rod, the limiting spring set in the groove works in conjunction with the tension rod and the sleeve hole on the upper rod. The length of the connecting pin of the upper rod and the lower rod assembly is changed, so as to change the length of the connecting pin according to the length of the chemical bonds in the molecular model. This greatly realizes the construction of molecular structure model blocks, ensuring that the fun of building blocks is also scientific. At the same time, because the molecular structure model blocks have a certain complexity, they can improve children's spatial imagination and logical thinking ability, and enable children of appropriate age to come into contact with more scientific knowledge, stimulating their interest and love for science.

Figure 9 As shown.

[0045] Several spherical bases 1 are connected by connecting pins 3. The connecting pins 3 are symmetrically provided with pressure joints 17 at both ends. The pressure joints 17 are designed with a spindle shape and are adapted to the interface 32. The connecting pins 3 are divided into an upper rod 7, a middle rod 8 and a lower rod 9. The upper rod 7 and the lower rod 9 are hollow structures, and the lower rod 9 is sleeved in the middle rod 8. One end of the upper rod 7 is fixedly connected to the middle rod 8. Several circular holes 15 are symmetrically opened on the middle rod 8. Each circular hole 15 has a groove 11 symmetrically arranged on both sides. A tensioning structure is installed in the groove 11. The upper rod 7 and the lower rod 9 are provided with a lifting structure at the end near the pressure joint 17.

[0046] like Figure 3 and Figure 4 As shown, the tensioning structure includes: a tension rod 14, limiting springs 16 symmetrically installed at both ends of the tension rod 14, and a tension plate 13 disposed on one end of the tension rod 14 near the sleeve hole 10; the end of the limiting spring 16 away from the tension rod 14 is fixedly installed on the inner wall of the groove 11, and the tension rod 14 extends through the tension plate 13 to the interior of the upper rod 7, and a tension block 12 is disposed at the other end of the tension rod 14; a plurality of sleeve holes 10 are arrayed at one end of the upper rod 7, and the diameter of each sleeve hole 10 corresponds to the diameter of the tension rod 14, and the diameter of the upper rod 7 and the diameter of the lower rod 9 correspond to the diameter of the insertion hole 2.

[0047] like Figure 5 and Figure 6 As shown, the lifting structure includes: several lifting plates 24, a lifting groove 28 disposed at one end of each lifting plate 24, and a connecting rod 29 disposed in the lifting groove 28; the several lifting plates 24 are installed alternately, and the two ends of the connecting rod 29 pass through the lifting groove 28 and connect to the lifting plates 24; the pressure connector 17 is divided into an inverted V interface 21 and a positive V interface 22, the two ends of the inverted V interface 21 and the positive V interface 22 are rotatably connected by a rotating rod 30, and the sides of the several lifting plates 24 are in contact with the inner walls of the two ends of the inverted V interface 21, and a conductive section 25 is disposed on the outer wall of the inverted V interface 21.

[0048] like Figure 7 and Figure 8 As shown, a fixing plate 26 is installed on one end of the inverted V-shaped interface 21 near the connecting pin 3. A long groove 31 is opened on the fixing plate 26. One end of the connecting rod 29 passes through the long groove 31, and a lifting rod 18 is installed on the connecting rod 29. The two ends of the inverted V-shaped interface 21 are rotatably connected to the fixing plate 26 through several rotating shafts. A connecting block 27 is provided on the fixing plate 26. The connecting block 27 and the fixing plate 26 are installed on one end face of the connecting pin 3. The lifting rod 18 extends through the connecting block 27 into the interior of the upper rod 7. An L-shaped rod 19 is connected to the end of the lifting rod 18 away from the connecting block 27. A long hole 20 is opened on the upper rod 7. One end of the L-shaped rod 19 extends to the outside through the long hole 20.

[0049] The lifting rod 18 moves upward, causing it to rotate on the rotating rod 30. The shuttle-shaped crimp connector 17 extends and retracts inward, narrowing its width, and then is inserted into the interface 32. The guide surface and guide section inside the interface 32 make contact with each other to conduct electricity. The shuttle-shaped crimp connector 17 is connected to the U-shaped structure inside the interface 32 to ensure a stable connection between the two components. At the same time, during long-term connection, heat may occur. The heat dissipation effect obtained by using the shuttle-shaped crimp connector 17 is better than that of the magnetic attraction structure with surface contact connection.

[0050] A method for using a multifunctional interactive educational toy, characterized by the following steps:

[0051] S1. Place several spherical bases 1 and several connecting pins 3 on the table, and open the recording panel. The recording panel is equipped with a main control system, which displays the three-dimensional model structure of the spherical bases 1.

[0052] S2. Open the connector 6 inside the spherical base 1, pick up the connecting pin 3, pull the L-shaped rod 19 to retract the crimp connector 17 of the shuttle structure inward, insert the crimp connector 17 into the interface 32 after passing through the socket 2, at which time the conductive section 25 and the conductive surface 33 are in contact with each other to achieve conductivity.

[0053] S3. After the main control system receives the conductive signal after the crimp connector 17 contacts the interface 32, it then displays the three-dimensional model structure of the connecting pin 3 in the recording panel.

[0054] S4. Based on the length of the chemical bonds in the molecular model, by pulling the tension rod 14 to align with the sleeve hole 10 on the upper rod 7, the length of the connecting pin 3 assembling the upper rod 7 and the lower rod 9 is changed.

[0055] S5. After changing the length of the connecting pin 3, pull the L-shaped rod 19 again to insert the crimp connector 17 into the interface 32 on the next spherical base 1 to achieve conductivity. The main control system continues to record the model structure until all the assembled molecular structure models are recorded.

[0056] Positioners 23 are installed at both ends of the connecting pin 3 in S4 to locate the length of the connecting pin 3, and the positioners 23 are connected to the main control system via wireless communication.

[0057] Example 2

[0058] Based on Embodiment 1, a control button is provided on the spherical base 1 to control the switch of the connector 6. During the splicing of the spherical base 1 and the connecting pin 3, the button is pressed to turn on the connector 6, and then the L-shaped rod 19 is pulled upwards. The connector 6 moves in the long groove 31 and the lifting groove 28 through the connecting rod 29. At the same time, the two ends of the inverted V interface 21 and the positive V interface 22 are rotated and connected through the rotating rod 30.

[0059] It should be noted that the bottom of the positive V-interface 22 is set to a closed state, and the two ends of the inverted V-interface 21 near the fixed plate 26 are set to an open and closed state. The lifting rod 18 moves upward and drives it to rotate on the rotating rod 30. The shuttle-shaped crimping head 17 extends and retracts inward, narrowing the width of the crimping head 17, and then inserts it into the interface 32. The guide surface and the guide section inside the interface 32 contact each other to achieve conductivity, thereby transmitting the electrical signal to the main control system. The main control system simulates the three-dimensional model structure of the connecting pin 3 and displays it on the recording panel.

[0060] Using the locators 23 at both ends of the connecting pin 3, two adjacent locators 23 transmit wireless signals to each other to determine the length of the connecting pin 3. Then, the length signal is transmitted to the main control system, and the length data is displayed in the recording panel.

[0061] In use, several spherical bases 1 and several connecting pins 3 are placed on a table. The recording panel is opened, and a main control system is installed inside the recording panel. The main control system displays the three-dimensional model structure of the spherical base 1. Then, the connector 6 inside the spherical base 1 is opened, the connecting pin 3 is picked up, and the L-shaped rod 19 is pulled to retract the spindle-shaped crimp connector 17 inward. The crimp connector 17 is inserted into the interface 32 through the insertion hole 2. At this time, the conductive section 25 and the conductive surface 33 come into contact with each other to achieve conductivity. After the main control system receives the conductive signal after the crimp connector 17 contacts the interface 32, it displays the three-dimensional model structure of the connecting pin 3 in the recording panel.

[0062] Based on the length of the chemical bonds in the molecular model, the length of the connecting pin 3 assembled by the upper rod 7 and the lower rod 9 is changed by pulling the tension rod 14 to correspond with the sleeve hole 10 on the upper rod 7. The L-shaped rod 19 is pulled again to insert the crimp connector 17 into the interface 32 on the next spherical base 1 to achieve conductivity. The main control system continues to record the model structure until the assembled molecular structure model is completely recorded.

[0063] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
