Description

[0001] MULTILATERAL MODULE ASSEMBLY [0002]

The present invention relates to a polyhedral modular assembly, and more particularly, to a polyhedral modular assembly having a structure in which unit modules are coupled by magnetic force.

Recently, attention has been paid to a polyhedron module type assembly in which specific functions are given to a cube-type unit module and unit modules having different functions are assembled together to form a finished product. These polyhedron modular assemblies are applied to toy and diagonal products aiming at creative play or learning, and recently they have been widely applied to DIY and robot products.

Each of the unit modules constituting the polyhedral modular assembly is generally provided with fastening means such as magnets on each surface of the unit module to facilitate disassembly / assembly between the modules. In addition, a connector or a contact terminal, which is provided as a separate component from the coupling means, may be added to each side of the unit module for connection of electrical signals between the unit modules. A technique for this is disclosed in Patent Document 1.

Patent Literature 1 discloses a portable telephone which comprises a main body casing formed in a polyhedral shape and having a hole formed at the center of each side thereof, and a hole formed in a side surface of the main casing, wherein a power transmission line, A plurality of coils connected to the plurality of reception lines, and a plurality of coils connected to the plurality of coils, the coils being connected to the plurality of coils, And an external coupling part including a second contact terminal protruded at a predetermined distance from a plurality of contact pieces electrically connected to any one of the first, second, and third data terminals, .

However, if the connector or terminal for connecting the electric signal to the unit module is provided as a separate component from the fastening means, the number of parts increases and the installation structure becomes complicated, making it difficult to miniaturize the unit module. In addition, for face coupling between the modules, the connectors must be paired in such a manner that a male connector is provided in the first unit module and a female connector is provided in the second unit module. According to such a coupling structure, since the same coupling structure can not be provided on all the surfaces of the unit module, the compatibility of the unit modules is lowered, so that there is a limitation in making various shapes by combining the unit modules.

On the other hand, in the case of conventional robot toys, when assembling a driving part such as a motor of a robot, it is necessary to use a connecting part provided by a toy maker or to assemble a small assembly assisting part by bolt / nut fastening method There is an inconvenience that power and control signal lines for driving the respective motors need to be connected separately from the outside of the robot.

Referring to FIG. 1, a unit module 100 according to the present invention includes a module body 101 and a magnetic and electrical connection function between the different unit modules 100 installed in the module body 101 Lt; RTI ID = 0.0 > 102 < / RTI > The polyhedron modular assembly has at least two or more unit modules 100 formed in various shapes.

The module main body 101 has a polyhedral body such as a cube, a hexagonal prism, an octagonal prism, or the like. The material of the module body 101 is preferably plastic, but it is not limited to this example.

The connection medium 102 is installed in each unit module 100 to perform magnetic and electrical connections between the unit modules 100. It is preferable that a plurality of connection mediums 102 are provided corresponding to respective surfaces of the unit module 100. For convenience of illustration, an example in which the connecting medium 102 is provided on one side of the module body 101 is shown in the figure.

As shown in Fig. 2, the coupling medium 102 includes a magnetic core 102a and a conductive layer 102b coated on the surface of the magnetic core 102a. As the magnetic core 102a, a usual ferromagnetic material can be employed. The conductive layer 102b is formed by coating a conductive material including a metal having relatively good electrical conductivity such as copper or gold. The surface of the conductive layer 102b surrounding the magnetic core 102a facing the outside of the unit module 100 is directly exposed to the outside. At this time, it is preferable that the exposed surface of the conductive layer 102b and the surface of the unit module 100 coincide on the same plane, or the exposed surface of the conductive layer 102b slightly protrudes by a predetermined height.

Preferably, the connecting medium 102 may have a tapered structure such that the connecting medium 102 has a gradually decreasing diameter with the front end thereof becoming a trapezoidal cross-sectional shape. According to this structure, it is possible to prevent the connection medium 102 from being detached from the unit module 100 while exposing the front surface of the connection medium 102 to the outside of the unit module 100.

Preferably, a plurality of connection media 102 are arranged at regular intervals with respect to the center of the unit module 100 to provide more powerful and symmetrical magnetic force. Also, when a plurality of connection media 102 are provided, there is an advantage that an electrical signal or the like can be transmitted through a plurality of channels. As shown in FIG. 1, the connection medium 102 may be arranged in at least one surface of the unit module 100, or a plurality of connection mediums 102 may be arranged in a '+' shape as shown in FIG. Alternatively, the connection medium 102 may be arranged in an "x" shape.

The magnetic body 103a is provided so as to be capable of rotating, reversing, and / or moving forward and backward in the inner space of the support holder 103b. According to this structure, when different unit modules 100 are brought into contact with each other at the time of assembling operation, the magnetic bodies can be relocated in the inner space of the support holder 103b in a state of being rotated or inverted such that their polarities are opposite to each other .

With this structure, it is possible to prevent the magnetic body 103a from being detached from the support holder 103b while exposing the front end surface of the magnetic body 103a to the outside of the support holder 103b.

The support holder 103b is made of a material such as aluminum which has no magnetic property and has a conductive surface. The support holder 103b functions to energize the circuit board and the magnetic body 103a together with the function of supporting the magnetic body 103a.

Alternatively, as shown in FIG. 5, the connection medium 104 may be of a donut shape, that is, a ring shape having a predetermined width. In this case, as shown in FIG. 6, the support holders 104b are preferably arranged concentrically from the center of the surface of the unit module 100 to provide a more powerful and symmetrical magnetic force. In addition, when a plurality of connection media 104 are provided, an electrical signal or the like can be transmitted through a plurality of channels as shown in FIG. Each of the connection media 104 is electrically connected to the first circuit board 110 disposed close to one side of the unit block 100 and electrically connected to the second circuit board 110 via the predetermined wiring 111, And is connected to the circuit board 112.

As shown in FIG. 8, the polyhedral modular assembly has various shapes in which unit modules 100 adjacent to each other are combined and combined by the magnetic force of the magnetic core 104a.

At this time, on the surface where the different unit modules 100 are in contact, the front end surface of the magnetic substance 103a is exposed on the surface of the unit module 100 to electrically connect the different unit modules 100, . In this case, the electric signals are transmitted in the order of the circuit boards 110 and 112, the support holder 104b and the magnetic body 103a in any unit module 100, and in the other unit module 100 coupled thereto, The magnetic body 103a, the support holder 104b, and the circuit boards 110 and 112 in this order.

In the case of applying the present invention, it is possible to make an assembling toy that can be electrically connected by only block assembly and remote-drive control, and can assemble and transmit signals before electric power from all sides of the unit module 100, A robot and the like can be produced.
