Description

Technical Field

[0001] The utility model belongs to the technical field of toys, and particularly relates to a magnetic building block. Background Art

[0002] As a toy for children, building blocks have the characteristics of simple structure, easy assembly, and varied shapes. They are suitable for users of different age groups. Frequent use of building blocks can well train people's ability to construct spatial three-dimensional models. Existing building blocks are generally arranged as a plug-in structure, that is, a building block unit is provided with a protrusion and a recessed hole for connecting with other building block units, so that the building blocks can be connected to each other to form different shapes. The advantage of plug-in building blocks is that the plug-in structure is firm. If the plug-in structure is designed with high dimensional accuracy, some complex shapes can be achieved. This type of building blocks is more suitable for people who are slightly older and have relatively complete hand strength and flexibility. For infants and young children, due to their insufficient hand strength, it is usually difficult to complete the plug-in connection between building block units. In addition, conventional building blocks have simple colors and shapes and are not very playable.

[0003] Therefore, it is necessary to provide an improved technical solution to address the deficiencies of the prior art. Summary of the Invention

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0024] In the description of the present invention, the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connection" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the terms can be understood according to specific circumstances.

[0025] According to the embodiment of the present utility model, Figures 1 to 3 As shown, a magnetic building block is provided, which includes at least two building block units, each of which includes a cavity and a magnetic component 1; the building block unit is a cubic structure, and a hollow magnetic accommodation cavity 201 is provided near the corners of the building block unit. The magnetic component 1 is disposed in the magnetic accommodation cavity 201. When two adjacent building block units are closely attached and the corners correspond, the corresponding magnetic components 1 in the building block units attract each other; at least one building block unit is provided with a light-emitting component 4 and / or a sound-emitting component (not shown), which emits a light signal and / or a sound signal after receiving a command signal. In this embodiment, the light-emitting component 4 is provided inside the building block unit.

[0026] Furthermore, the light-emitting component 4 includes a light-emitting circuit board 401, and a charging port 402, a lamp bead 403, a battery 405 and a switch 404 arranged on the light-emitting circuit board 401; a corresponding hole is opened on the outer wall of the building block unit corresponding to the charging port 402; the charging port 402 is used to plug in a charging device to realize charging and storing of the battery 405. After the switch 404 of the light-emitting component 4 receives the switch 404 instruction, the lamp bead 403 responds by lighting up or off.

[0027] Furthermore, the interior of the building block unit is hollowed out, and the building block unit includes a hollow connecting plate 202 for fixing the light-emitting component 4. The connecting plate 202 is provided with a hole for accommodating the lamp beads 403 at a position corresponding to the lamp beads 403, so that the light-emitting circuit board 401 is as close to the connecting plate 202 as possible, thereby realizing the most compact arrangement of the light-emitting component 4 in the narrow space inside the building block unit.

[0028] Furthermore, in order to better guide the light of the light-emitting component 4 to the outside of the building block unit, in this embodiment, the connecting plate 202 is a light-conducting material plate, which is connected to the inner walls of multiple sides of the building block unit. When the lamp beads 403 emit light, the light is evenly guided to the sides of the connected building block unit through the connecting plate 202, and the connecting plate 202 made of light-conducting material can evenly disperse the light to the inside of the entire building block unit, thereby achieving uniform lighting of the entire building block unit. In order to achieve lighting, the side walls of the building block unit are all made of light-transmitting materials, that is, they have a certain light transmittance.

[0029] Furthermore, the building block unit is a cubic structure, and the cavity includes an outer shell body 2 and a cover plate 3. The outer shell body 2 is a hollow structure, and the cover plate 3 is installed at a pair of side openings of the outer shell body 2; a magnetic accommodating cavity 201 is provided at the inner corners of the opening of the outer shell body 2, and the size of the magnetic accommodating cavity 201 is larger than the size of the magnetic component 1, so that the magnetic component 1 can move freely in the magnetic accommodating cavity 201 to adjust its posture and attract the magnetic component 1 corresponding to the adjacent building block unit.

[0030] In other embodiments of the present invention, the magnetic component 1 close to the switch 404 can move in the accommodating cavity along the direction of distance from the switch 404, and the switch 404 is a magnetic switch; when the magnetic component 1 is not affected by external magnetic force, the magnetic component 1 is attracted by the magnetic switch and approaches the magnetic switch, and the magnetic switch disconnects the circuit of the lamp bead 403 under the action of magnetism; when two adjacent magnetic units approach each other, the magnetic component 1 is attracted by the magnetic components 1 corresponding to the adjacent magnetic units and moves away from the magnetic switch, and the magnetic switch loses its magnetic effect and closes the circuit of the lamp bead 403. During use, when the building block unit is not assembled with other building block units, the magnetic component 1 close to the magnetic switch approaches the magnetic switch under the attraction of the magnetic switch, thereby disconnecting the magnetic switch, and the lamp bead 403 does not light up at this time; when the building block unit is assembled with other building block units, since the attraction between the magnetic components 1 between the two adjacent building block units is greater than the attraction between the magnetic component 1 and the magnetic switch, the magnetic component 1 moves away from the magnetic switch, thereby causing the magnetic switch to lose its magnetic attraction and close the circuit of the lamp bead 403, and the building block unit lights up.

[0031] In other embodiments of the present invention, the building block unit may include a cube and a cuboid, the smallest side of the cuboid building block unit is a square with a side length equal to the side length a of the cuboid building block unit, and the long side of the cuboid building block unit is an integer multiple of the side length a of the cuboid building block unit; magnetic accommodating cavities 201 are arranged at intervals along the length direction near the long side of the cuboid building block unit, and a magnetic component 1 is arranged in the magnetic accommodating cavity 201; the distance d between adjacent magnetic accommodating cavities 201 in the length direction of the cuboid building block unit and the width b of the magnetic accommodating cavity 201 and the side length a of the building block unit satisfy the following relationship: the distance d1 between the building block accommodating cavity located at the end of the length direction of the cuboid building block unit and the adjacent magnetic accommodating cavity 201 is equal to a-1.5b; the distance d1 between the building block accommodating cavity located in the middle of the length direction of the cuboid building block unit and the adjacent magnetic accommodating cavity 201 is equal to ab. By combining rectangular building block units with cube building block units, you can make some buildings such as bridges, making up for the limitation of the shape of cube building block units. Figure 4 A schematic diagram showing the magnetic attraction between the cube building block unit and the rectangular building block unit when they are built.

[0032] To sum up, the magnetic building blocks provided by the present invention have magnetic components 1 arranged inside the building block units, so that the building block units are attracted to each other by the magnetic components 1 when they are assembled, ensuring that the appearance of the building block units is flat, easy to assemble, and reducing the difficulty of assembling for infants and young children. By providing luminous components and / or generating components, the fun and playability of the building block toys are improved, making them more attractive to infants and young children and easier for them to assemble and play.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
