Description

A combination of magnetic building blocks

Technical field

The invention relates to the field of building blocks, in particular to a combination of magnetic building blocks.

Background technique

Existing building block toys mostly adopt a tenon-and-mortise structure connection method. Such building block toys mainly rely on mechanical force to be stacked on each other, can only splice some very simple shapes, and are easy to collapse.

At the same time, the building blocks are mostly plastic or wooden building blocks, and there are hidden safety hazards when children use them, and they are not suitable for use by young children.

Summary of the invention

Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a magnetic building block combination that uses magnets to facilitate the splicing of various shapes, and at the same time uses cubes, triangular pyramids, triangular prisms and cubes with missing corners to achieve various shapes. In addition, the outer skin of the building blocks is made of fabric, and the interior is made of sponge, which can improve safety, economical and environmental protection.

The present invention provides a combination of magnetic building blocks, including building blocks of at least 4 shapes. The building blocks include a closed cloth outer skin, the inner of the cloth outer skin is filled with a sponge body matching the overall shape of the cloth outer skin, and a magnet is arranged between the sponge body and the cloth outer skin; For the fixation of the magnet, it can be glued to the outside of the sponge or inside the outer skin of the cloth, or it can be directly inserted into the gap between the sponge and the outer skin of the cloth;

The 4 types of building blocks are square building blocks, triangular pyramid building blocks, triangular prism building blocks and missing corner building blocks;

The shape of the triangular prism block is consistent with the shape obtained by cutting along the diagonal line of the upper and lower sides of the square block;

The shape of the triangular pyramid building block is consistent with the triangular pyramid shape cut along the four corners of the square volume block, and the corresponding shape after cutting the triangular pyramid is consistent with the shape of the missing corner building block;

The magnets on the same side of the building blocks of various shapes have the same magnetism towards the outside;

The magnets on at least one side of all building blocks are N poles facing outwards, and the magnets on at least one side of all building blocks are S poles facing outwards.

In a further improvement of the present invention, the cutting surfaces of the triangular pyramid building block and the missing corner building block have no magnet distribution, the cutting surface of the triangular prism building block has no magnet distribution, and the corners of the remaining surfaces are distributed with magnets. By adopting this technical solution, it is convenient to take advantage of various shapes and combine them into more shapes of non-cubes.

In a further improvement of the present invention, the magnets of the same shape of the building blocks have the same magnetic properties on the outward side. Adopting this technical scheme is convenient for children to splice when they are in use.

In a further improvement of the present invention, the side length of the square volume block is 5-20 cm. Adopting this technical scheme is convenient for children to use.

As a further improvement of the present invention, the magnetic building block assembly further includes one or more of sphere, cuboid, cylinder, terrace, and pyramid-shaped building blocks. By adopting this technical scheme, the types of splicing products are increased.

The beneficial effects of the present invention are:

(1) The building block combination uses magnets to realize the splicing of various shapes, which is more suitable for children to operate. At the same time, compared with the traditional tenon-and-mortise structure connection, more shapes can be combined.

(2) This building block uses cubes, triangular pyramids, triangular prisms and cubes with missing corners. The building blocks of various shapes are "cut" from cubes. Therefore, the mutually attracted surfaces of the magnets match when splicing, which is convenient for splicing. Improve the stability, and at the same time the placement of the magnet can take advantage of each shape to realize the splicing of multiple shapes.

(3) The outer skin of the building blocks is made of fabric, and the interior is made of sponge, which can improve the safety of use, is economical and environmentally friendly, and is light in weight. It is suitable for children, especially young children.
