Description
Technical Field
[0001] The invention belongs to the field of toys, and in particular relates to an educational puzzle assembly. Background Art
[0002] Jigsaw puzzles are fun and have a high rate of reuse. They are very beneficial for improving imagination, creativity, and hands-on ability. Therefore, they are loved by the general public and are especially suitable for use as children's enlightenment teaching aids.
[0003] Jigsaw puzzles generally include multiple puzzle blocks, and the puzzle blocks can be connected together in different ways. The existing ways of connection mainly include the following: (1) In two puzzle blocks connected to each other, one puzzle block is formed with at least one concave connection hole, and the other puzzle block is formed with at least one convex connection column, and the multiple puzzle blocks are connected together by plugging the connection column and the puzzle hole into each other. (2) The blocks are connected by magnetic attraction. The magnetic attraction can be a permanent magnet built into a common magnetic sheet, or a magnetic attraction type electronic building block system disclosed in Chinese invention patent CN 201310037891.3. Each electronic building block module includes a circuit board with a functional circuit, a plug connector connected to the edges of both sides of the circuit board, and a socket connector docked with the plug connector. The circuit board is provided with three signal lines, namely a positive power line, a data signal line, and a negative power line. The plug connector and the socket connector both include an insulating body and three conductive terminals arranged side by side on the insulating body. The insulating body has a docking surface for connecting with another connector. The docking surface of the insulating body is provided with a plurality of receiving grooves, and permanent magnets are installed in the receiving grooves. The conductive terminals penetrate the interior of the insulating body and extend outside the docking surface. The three conductive terminals are respectively a positive power terminal, a data signal terminal, and a negative power terminal. The three conductive terminals are respectively connected to corresponding signal lines on the circuit board. The plurality of electronic building block modules include a power supply and signal generation module for providing power and signal source, and the other plurality of electronic building block modules are sequentially cascaded with the power supply and signal generation module.
[0004] The existing splicing methods between the puzzle blocks in the puzzle toys have the following shortcomings: ① The splicing column and the splicing hole, such as the snap-on type, simply rely on the friction between the two to ensure the connection and fixation, which is easy to cause the connection to loosen due to long-term use. At the same time, the adjacent puzzle blocks are overlapped after splicing, and there is an overlapping part between the two, which makes the puzzle toy as a whole relatively crude and not delicate enough, and is not suitable for older children to play with; ② The magnetic electronic building block system requires a circuit board to be set in the electronic building block module, which is expensive; the plug connector and the socket connector therein can only realize the connection of the electronic building block modules in the horizontal direction, and it is difficult to realize three-dimensional splicing. When used for three-dimensional splicing, the electronic building block module at the top is easy to fall due to gravity. Not only is the splicing strength insufficient, but the splicing diversity is low, which limits the creativity and imagination of the user. Summary of the invention
[0005] The invention object of the present application is to provide an educational splicing component with strong splicing diversity, high splicing strength and the ability to achieve three-dimensional splicing.
[0006] In order to achieve the above-mentioned invention object, the technical solution of this application is as follows:
[0007] A puzzle assembly comprises at least two puzzle pieces which are detachably spliced together. Among the two puzzle pieces which are spliced together, one puzzle piece is provided with at least one circumferentially open connecting channel and the outer end of the connecting channel is located at the edge of the puzzle piece, and the other puzzle piece is provided with at least one through hole, wherein a first thread segment is provided in the connecting channel, a screw rod passes through the through hole and the connecting channel in sequence, and the screw rod is threadedly connected to the first thread segment, and a positioning structure is provided between the puzzle piece provided with the through hole and the screw rod.
[0008] The present application provides a connecting channel on the puzzle block, and the first threaded section provided therein facilitates the installation of a screw between the connecting channel and the through hole; the puzzle blocks are spliced by installing a screw between the connecting channel and the through hole, which can not only achieve splicing in the horizontal direction, but also achieve splicing in the vertical direction, thereby obtaining a multi-level three-dimensional splicing effect, the strength of the threaded fixation is very effective, and the puzzle blocks will not fall due to gravity during three-dimensional splicing.
[0009] Since the connecting channel is circumferentially open, the size of the channel is not limited by the thickness of the blocks, which makes it possible for the outer diameter of the screw used to be equal to or even greater than the thickness of the blocks, further effectively ensuring the connection strength between the blocks; for thinner blocks, providing a circumferentially open connecting channel can also greatly reduce the processing difficulty and cost, and the yield rate is also higher.
[0010] The educational puzzle toy of the present application is used in the field of education, which can not only cultivate students' hands-on ability, but also can let children's imagination play freely because of the diverse splicing methods and high splicing strength. Children do not have to feel frustrated and lose interest because the splicing components cannot realize their imaginations, and truly play the enlightenment and educational role of the educational puzzle components. In the above-mentioned educational puzzle components, the positioning structure includes a head disposed at the end of the screw and having a size larger than the aperture of the through hole and / or a second threaded section disposed on the inner wall of the through hole, and the screw is threadedly connected with the second threaded section. The head that plays a limiting role and the second threaded section that establishes a connection between the screw and the puzzle block with the through hole so that the two are mutually squeezed can both prompt the screw to approach the puzzle block with the through hole until it abuts against the puzzle block with the connecting channel, prevent the puzzle block with the through hole and the puzzle block with the connecting channel from being separated, and ensure that the two are firmly spliced.
[0011] In the above-mentioned puzzle assembly, the puzzle pieces are in the form of sheets, and at least one side of the puzzle piece with the connecting channel is provided with a strip groove that penetrates the connecting channel; or, both sides of the puzzle piece with the connecting channel are provided with strip grooves that penetrate the connecting channel. The strip groove is the reason why the connecting channel can be open circumferentially. There can be one strip groove or two strip grooves. When two strip grooves are provided, the two strip grooves are relatively arranged on the two sides of the first assembly piece. The two strip grooves make the circumferential openness of the connecting channel higher, which is convenient for installing a screw with a larger outer diameter to achieve a higher strength splicing.
[0012] In the splicing relationship, the positions of the puzzles with connecting channels and the puzzles with through holes and the splicing functions they play are relatively fixed, which will limit the splicing diversity of the puzzles to a certain extent. In order to remove this limitation, in the above-mentioned puzzle assembly, the inner end and / or the outer end of the connecting channel are provided with a flared area so that the flared area can be used as a through hole alone or two flared areas can be used as a through hole after splicing; the through hole is a circumferentially closed through hole or the through hole is connected to a strip channel whose outer end extends to the edge of the puzzle so that the strip channel can be used as a connecting channel.
[0013] After the inner and / or outer ends of the connecting channels of the puzzle blocks with connecting channels are provided with flared areas, the puzzle blocks with connecting channels have both the function of connecting channels and the function of through holes (realized by the flared areas); after the strip channels connecting the edges of the puzzle blocks and the through holes are provided on the puzzle blocks with through holes, the puzzle blocks with through holes have both the function of through holes and the function of connecting channels (realized by the strip channels); the functions of the puzzle blocks, which originally had relatively single positions and functions in the splicing relationship, are made more diverse, and any splicing positions can be reached according to the imagination of the user, and the splicing combinations between the puzzle blocks are more diverse, which greatly enhances the fun of the educational puzzle assembly of the present application and has a better educational enlightenment effect.
[0014] Obviously, a flared area can also be provided at the outer end of the strip-shaped channel so that the flared area can be used as a through hole alone or two flared areas can be combined to be used as a through hole. When the flared area is provided at the outer end of the connecting channel, two blocks with the same flared area can combine the flared areas at their respective edges to form a circumferentially substantially closed through hole. By installing bolts in the through hole, at least three blocks can be spliced at the same time.
[0015] In the above-mentioned puzzle assembly, the puzzle pieces are all made of sheet materials and are in regular or irregular geometric shapes. The shape of the puzzle pieces mainly depends on the specific combination concept and arrangement of the specific puzzle pieces.
[0016] In order to increase the fun of the puzzle assembly, in the above-mentioned puzzle assembly, at least two puzzle blocks that are detachably spliced together are connected with a circuit board and an electric actuator, the circuit board and the electric actuator are connected by a wire, and a circuit communication interface connection structure is provided between the circuit board and the wire.
[0017] Adding a circuit control system to the puzzle assembly helps to further improve the fun and train the user's logical thinking ability. The puzzle blocks connected to the electric actuator can be directly spliced with the puzzle blocks connected to the circuit board, or they can be spliced together through at least one puzzle block that is not connected to the electric actuator and the puzzle block connected to the circuit board; but it should be noted that regardless of whether the two puzzle blocks are directly connected, the circuit board and the electric actuator are directly connected through wires, and the communication between the two does not pass through the puzzle blocks that are not connected to the electric actuator. This avoids the defect of invalid extension of the transmission path of the current and / or data signal between the functional module and the control circuit board caused by the cascade of electrical connections and / or signal connections of the puzzle blocks connected to the circuit board-the puzzle blocks that are not connected to the electric actuator-the puzzle blocks connected to the electric actuator. At the same time, it also reduces the production requirements of the intermediate puzzle blocks and reduces the difficulty of troubleshooting after the transmission path is disconnected for no reason.
[0018] Since the main audience of the educational puzzle assembly of the present application is teenagers, a safe and effective connection between the circuit board and the electric actuator is necessary. The above purpose can be achieved by optimizing the circuit communication interface connection structure.
[0019] In the above-mentioned puzzle assembly, the circuit communication interface connection structure includes a first connector arranged on a circuit board and a second connector arranged on a wire, the first connector includes an insulating seat fixed on the circuit board, the insulating seat is provided with at least one first conductive terminal, the second connector includes a connector seat, the connector seat is provided with at least one second conductive terminal, a magnetic connection structure is provided between the insulating seat and the connector seat, and when the insulating seat and the connector seat are magnetically connected, the first conductive terminal and the second conductive terminal are contacted and connected one by one.
[0020] The magnetic connection structure enables the insulating seat and the connector seat to be magnetically connected. Under the action of the magnetic attraction, the first conductive terminal and the second conductive terminal can be contacted and connected one by one. The magnetic connection method makes the connection and disconnection of the circuit board and the electric actuator very easy and convenient. The communication between the circuit board and the electric actuator with wires can be achieved without plugging and unplugging. Moreover, the loss of the magnetic connection seat and the magnetic connector is very small, the service life is long, and the damage to the first connector and the second structure caused by repeated plugging and unplugging is completely eliminated.
[0021] In the above-mentioned puzzle assembly, the magnetic connection structure includes at least one first magnet arranged on the insulating seat and at least one second magnet arranged on the connector seat, and the polarities of the first magnet and the second magnet are opposite; there are two first magnets arranged at both ends of the insulating seat, and the first magnet is passed through the insulating seat; there are two second magnets arranged at both ends of the connector seat, and the second magnet is passed through the connector seat. The two first magnets are respectively located on both sides of the first conductive terminal, and the two second magnets are respectively located on both sides of the second conductive terminal, so as to ensure that the first conductive terminal and the second conductive terminal always keep in contact. When the number of the first conductive terminal and the second conductive terminal is greater than one, this arrangement of the first magnet and the second magnet is very beneficial to ensure that all the first conductive terminals and the second conductive terminals keep in contact.
[0022] Preferably, the polarities of the two first magnets at both ends of the insulating seat are opposite; the polarities of the two second magnets at both ends of the connector seat are opposite. This ensures that the insulating seat and the connector seat are always magnetically attracted in the same direction, avoiding connection errors that may occur due to reverse magnetic attraction.
[0023] In the above-mentioned puzzle assembly, there are a plurality of first conductive terminals arranged in a row, and the first conductive terminals are inserted into the insulating seat; there are a plurality of second conductive terminals arranged in a row, and the second conductive terminals are inserted into the connector seat; a positioning notch is provided on the top of the first conductive terminal, and a positioning convex head protruding from the connector seat is provided on the top of the second conductive terminal, and the positioning convex head matches the positioning notch, and the top of the first magnet is flush with the surface of the insulating seat, and the top of the second magnet is flush with the surface of the connector seat. In this way, when the first magnet and the second magnet are magnetically connected, the surface of the insulating seat is in contact with the surface of the connector seat, so that the positioning convex head can be embedded in the positioning notch to achieve contact and connection. When the two are in contact, the positioning notch can form a circumferential wrapping around the positioning convex head, thereby increasing the contact surface between the first conductive terminal and the second conductive terminal.
[0024] In the above-mentioned puzzle assembly, the positioning protrusion is axially movably connected to the connector seat, an anti-dropping limit structure is provided between the positioning protrusion and the connector seat, a wiring pin is provided at the inner end of the positioning protrusion, and a conductive elastomer is provided between the positioning protrusion and the wiring pin; the positioning recess is bowl-shaped, the positioning protrusion is ball-shaped, and the positioning recess matches the positioning protrusion; the lower end of the first conductive terminal is welded to the circuit board, and a gap is provided between the insulating seat and the circuit board. The conductive elastomer is conducive to driving the positioning protrusion to always rest against the positioning recess. The gap left between the insulating seat and the circuit board can help the circuit board and the insulating seat to dissipate heat.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] (1) The present application provides a connecting channel on the puzzle block, and a first threaded section provided in the connecting channel facilitates the installation of a screw between the connecting channel and the through hole; by installing a screw between the connecting channel and the through hole to achieve splicing of the puzzle blocks, not only can splicing in the horizontal direction be achieved, but also splicing in the vertical direction can be achieved, thereby obtaining a multi-level three-dimensional splicing effect. The strength of the threaded fixing is very effective, and the puzzle blocks will not fall due to gravity during three-dimensional splicing.
[0027] (2) In the present application, the connecting channel on the puzzle block is circumferentially open, so the size of the channel is not limited by the thickness of the puzzle block. This makes it possible for the outer diameter of the screw used to be comparable to or even greater than the thickness of the puzzle block, further effectively ensuring the connection strength between the puzzle blocks. For puzzle blocks with thinner thickness, the provision of a circumferentially open connecting channel can also greatly reduce the processing difficulty and cost, and the yield rate is also higher.
[0028] (3) The present application provides a flared area at the inner end and / or outer end of the connecting channel of the puzzle block provided with the connecting channel, so that the puzzle block provided with the connecting channel has both the function of the connecting channel and the function of a through hole (realized by the flared area); and after a strip channel connecting the edge of the puzzle block and the through hole is provided on the puzzle block provided with the through hole, the puzzle block provided with the through hole has both the function of the through hole and the function of a connecting channel (realized by the strip channel); thereby, in the splicing relationship, the functions of the puzzle blocks that originally had relatively single positions and functions are more diverse, and any splicing position can be reached according to the imagination of the user, and the splicing combinations between the puzzle blocks are more diverse, which greatly enhances the fun of the educational puzzle assembly of the present application and has a better educational enlightenment effect.
[0029] (4) The present application also connects a circuit board and an electric actuator to at least two detachably connected blocks, and the circuit board and the electric actuator are connected by wires; adding a circuit control system to the puzzle assembly helps to further improve the fun and train the user's logical thinking ability. The block connected to the electric actuator can be directly connected to the block connected to the circuit board, or it can be connected together through at least one block not connected to the electric actuator and the block connected to the circuit board; but it should be noted that regardless of whether the two blocks are directly connected, the circuit board and the electric actuator are directly connected by wires, and the communication between the two does not pass through the block not connected to the electric actuator, thus avoiding the defect of invalid extension of the transmission path of the current and / or data signal between the functional module and the control circuit board caused by the cascade of electrical connections and / or signal connections of the block connected to the circuit board-the block not connected to the electric actuator-the block connected to the electric actuator, and at the same time reducing the production requirements of the intermediate blocks and reducing the difficulty of troubleshooting after the transmission path is disconnected for no reason.
[0030] (5) The present application adopts a magnetic connection structure to realize the magnetic connection between the insulating seat and the connector seat. Under the action of the magnetic attraction, the first conductive terminal and the second conductive terminal can be contacted and connected one by one. The magnetic connection method makes the connection and disconnection of the circuit board and the electric actuator very easy and convenient. The communication between the circuit board and the electric actuator with wires can be realized without plugging and unplugging. In addition, the loss of the magnetic connection seat and the magnetic connector is very small, and the service life is long, which completely eliminates the damage to the first connector and the second structure caused by repeated plugging and unplugging.

Children do not have to feel frustrated and lose interest because the splicing components cannot realize their imaginations, and the educational puzzle components can truly play an enlightening and educational role.
