Description

Technical field

[0001] The present utility model relates to the technical field of building blocks, in particular a universal magnetic building block set with a rounded appearance. Background technology

[0002] Magnetic building blocks, as the name suggests, are toys that combine the properties of magnets with the fun of building with blocks. These toys typically consist of several small magnetic building block units, each containing a powerful embedded magnet. This allows the building block units to stick together and form various stable structures.

[0003] The magnetic properties of these building blocks offer children a completely new building experience. Compared to traditional building blocks, magnetic blocks are easier to connect and combine because the magnetic force automatically helps align and firmly connect the blocks. This allows children to more easily create complex three-dimensional structures such as bridges, houses, vehicles, and more.

[0004] The main structure of current magnetic building blocks typically consists of a main body, a bottom cover, a top cover, and magnets. However, current magnetic building blocks usually have a pointed outer shape that can easily scratch or injure human skin, making them relatively safe. Furthermore, most current magnetic building blocks do not have a light-up function, and it is not possible to switch between configurations with and without light-up functionality, which fails to meet different usage requirements. Therefore, there is a need to improve current magnetic building blocks. Content of the present utility model

[0005] In light of the foregoing, the present utility model aims to provide a universal magnetic building block set with a rounded appearance, which effectively solves the problem that existing magnetic building blocks do not meet safety requirements and that switching between a configuration with and without a lighting function is not possible.

[0006] To achieve the above objective, the present utility model uses the following technical solution: A universal magnetic building block set with a rounded design includes a main body, a bottom cover, a first top cover, a second top cover, and magnets. All corners and edges of the main body are rounded, and the main body has a recess open at its top and bottom to accommodate a light unit. The bottom cover fits into the lower opening of the recess and is permanently attached to the main body. The first top cover has a closed plate structure and is removable from the top of the recess. The second top cover features a button cover for triggering the light unit's switch and is removable from the top of the recess. The magnets are fixed within the main body.

[0007] Preferably, the outer contour of the main body is square.

[0008] Preferably, the upper opening and the lower opening of the receiving chamber are both square, and accordingly, the lower cover, the first upper cover and the second upper cover each have a square plate structure.

[0009] Preferably, the main body consists of a translucent material.

[0010] Preferably, the main body is made of plastic.

[0011] Preferably, the bottom cover is permanently attached to the main body by ultrasonic welding.

[0012] Preferably, insertion grooves are formed at the individual corners and edges of the upper opening and the lower opening of the receiving space, and the magnets are present in multiple quantities, with the multiple magnets being inserted and fixed in the corresponding insertion grooves.

[0013] Preferably, the magnets have a cuboid structure.

[0014] Preferably, inwardly projecting lower columns are formed on each inner wall of the receiving space, and each lower column is provided with a lower fixing hole; accordingly, several lower fixing columns project from the inner surface of the lower cover, and the several lower fixing columns are each inserted into the corresponding lower fixing holes and fixed by a mate fit.

[0015] Preferably, the lower columns are present in four quantities and are arranged evenly around the center of the main body, and the lower fixing columns are also present in four quantities.

[0016] Preferably, upper columns projecting inwards are formed on each inner wall of the receiving space, and each upper column is provided with an upper fixing hole; accordingly, several upper fixing columns project from the inner surface of the first upper cover and the inner surface of the second upper cover, and the several upper fixing columns are each inserted into the corresponding upper fixing holes and fixed by a mate fit.

[0017] Preferably, the upper columns are present in four quantities and are arranged evenly around the center of the main body, and the upper fixing columns are also present in four quantities.

[0018] Preferably, the bottom cover, the first top cover and the second top cover are each made of a translucent material.

[0019] Preferably, the bottom cover, the first top cover and the second top cover are each firmly connected to the main body by ultrasonic welding.

[0020] Preferably, the bottom cover, the first top cover and the second top cover are each made of plastic.

[0021] Compared to the prior art, the present utility model exhibits obvious advantages and positive effects that can be derived from the above technical solutions: The design of the utility model, with all corners and edges of the main body rounded, gives the product a smooth appearance, minimizing the risk of scratches or injuries to human skin and thus significantly improving safety, fully meeting safety requirements.
