Detailed Description

The utility model is further described below with reference to examples. The following examples are presented only to aid in the understanding of the utility model. It should be noted that it will be apparent to those skilled in the art that modifications can be made to the present utility model without departing from the principles of the utility model, and such modifications and adaptations are intended to be within the scope of the utility model as defined in the following claims.

Example 1

As an embodiment, as shown in fig. 1 to 7, the magnetic interaction toy with changeable magnetic attraction and repulsion force comprises an active module 1, a passive module 2 and a game platform, wherein plugs for installing plug-ins are arranged at the tops of the active module 1 and the passive module 2, so that players can conveniently define game roles and self-assemble the toy. The game platform is a transparent flat plate with array holes, the game map is pressed below the game platform, and the game platform is provided with array round holes, so that the self-defined barrier and fence modules can be inserted into the round holes to be fixed.

As shown in fig. 1 and 3, an arc gap is formed on one side of the active module 1, a cavity is formed at the bottom of the active module 1 toward one side of the arc gap, a center magnet 11 is fixed at one side of the cavity toward the arc gap, an outer fixed magnet 12 is fixed at the other side of the center magnet 11 away from the arc gap, an outer movable magnet 13 is further arranged in the cavity, and because the outer movable magnet 13 and the outer fixed magnet 12 are mutually exclusive transversely, the outer fixed magnet 12, the outer movable magnet 13 and the center magnet 11 are distributed in a 120-degree stable manner under the condition of no external force, and the opening angle between the two outer movable magnets 13 is opposite to the arc gap of the active module 1. The outer movable magnet 13 rolls around the center magnet 11 when being interfered by external magnetic force; the bottom of the cavity is made of transparent acrylic hard material, so that the position and the relative movement condition of the magnet in the driving module 1 can be observed from the outside.

The specific method for fixing the center magnet 11 and the outer fixed magnet 12 in the cavity is that a small cylinder is arranged in the cavity through a shaft hole connection mode, the center magnet 11 and the outer fixed magnet 12 are annular and are sleeved and fixed on the small cylinder in the cavity, and the center magnet 11, the outer fixed magnet 12 and the outer movable magnet 13 are annular magnets which are magnetized in the same shape and the same number in the axial direction.

The passive module 2 is provided with a plurality of convex corners, and in this embodiment, the passive module 2 is a flat regular triangular prism with rounded corners, i.e. three convex corners. Each lobe has a passive magnet 21 fixed to it, so that it can be magnetically acted on in multiple directions. Specifically, a small cylinder is arranged at the lobe, and the passive magnet 21 is also ring-shaped with the same shape and magnetism and is sleeved and fixed on the small cylinder of the lobe. The center magnet 11, the passive magnet 21, the outer fixed magnet 12 and the outer movable magnet 13 all adopt neodymium iron boron permanent magnets with phi 7mm multiplied by phi 4.5mm multiplied by 4mm, the height of the passive magnet 21 is consistent with the height of the magnets in the driving module 1, and the profiles of the convex angles of the passive magnet 21 and the passive module 2 are tangent, so that the connection between the passive magnet 21 and the center magnet 11 is more sensitive. All ring magnets are magnetized axially and "side by side" in a plane perpendicular to the axis of magnetization, which means that when two magnets of opposite magnetization directions, i.e. opposite poles, are brought together, they attract each other in the lateral direction, and magnets of the same magnetization direction repel each other.

The rough surface is arranged at the bottom of the driving module 1, so that a certain friction force exists between the driving module 1 and the game platform, the hand feeling is improved, the driving module 1 can be better controlled to be close to the driven module 2 at a uniform speed, and the touch feedback of repulsive force and attractive force is experienced. As shown in fig. 5, the passive magnet 21, the outer fixed magnet 12, and the outer sliding magnet 13 have the same magnetic poles and have opposite magnetic poles to the center magnet 11. The active module 1 and the passive module 2 have the characteristics of distant repulsion and close attraction, and have a critical distance, and are in an unstable equilibrium state when the passive magnet 21 and the center magnet 11 are at the critical distance. The lobes match the shape of the arcuate indentations on the active module 1.

As shown in fig. 5a, when the distance d between the active module 1 and the passive module 2 is large, the magnetic repulsive force of the edge magnets is dominant, and when the distance d is infinite, the angle θ between the line connecting the outer fixed magnet 12 and the center magnet 11 and the vertical line is 30 °.

As shown in fig. 5b, when the distance d between the active module 1 and the passive module 2 is smaller than the critical distance, the magnetic attraction between the center magnets of the active member and the passive member is dominant, and the included angle θ becomes smaller as the distance d becomes smaller.

As shown in fig. 5c, the passive module 2 is attracted to the center magnet 11 by the active module 1, and the passive magnet 21 becomes a new edge magnet, and the angle θ is 0 degrees.

As shown in fig. 2 and 4, when the passive module 2 and the active module 1 are connected, one of the convex corners of the passive module 2 is inserted into the arc-shaped notch of the active module 1, the passive magnet 21 is magnetically attracted to the center magnet 11, and the passive magnet 21, the outside fixed magnet 12 and the outside movable magnet 13 are rotationally symmetrical about the center magnet 11 by 90 degrees.

When the passive module 2 is pushed to the obstacle module or surrounded and fixed by the plurality of active modules 1, the arc notch of the active module 1 is further close to the center magnet 11, and the attraction between the center magnet 11 and the passive magnet 21 is continuously increased until the center magnet 11 and the passive magnet 21 are magnetically attracted, so that the passive module 2 is captured. Games like table hockey, football, barrier running can also be played, i.e. passive module 2 is captured without active module 1, but is made to move continuously, with impact or movement as a core play.

In the interaction process, the user can experience different touch sensations such as instant attraction force, continuous pushing force, strong anti-repulsive force and the like. The magnetic interaction toy with changeable attraction and repulsion magnetic force is more focused on rich and continuous touch experience in the magnetic interaction process than other magnetic toys, and is helpful for experience type perception and learning of physical knowledge such as magnetism.

The slide way 3 is provided with a slide block 4, one end of the slide block 4 is inserted into the demonstrator and is fixedly provided with a passive magnet 21, which corresponds to the passive module 2, and the passive magnet 21 is only one side of the demonstrator which actively moves; the end of the slideway 3 in the demonstrator is fixedly provided with a central magnet 11, one side, far away from the slideway 3, of the central magnet 11 is fixedly provided with an outer fixed magnet 12, and two outer sliding magnets 13 are magnetically attracted to the two sides of the central magnet 11, which is equivalent to the driving module 1.
