Detailed ways

The present invention will be further described below in conjunction with examples. The following description of the examples is provided only to assist understanding of the present invention. It should be pointed out that for those skilled in the art, several modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

Embodiment 1

As an embodiment, as shown in Figures 1 to 7, this magnetic interactive toy with switchable magnetic attraction and repulsion includes an active module 1, a passive module 2 and a game platform. The tops of the active module 1 and the passive module 2 are equipped with There are plugs for installing plug-ins, allowing players to define game characters and assemble them themselves. The game platform is a transparent flat plate with an array of holes. The game map is placed under the game platform. There is an array of round holes on the game platform. Customized obstacles and fence modules can be inserted into the round holes to fix them.

As shown in Figures 1 and 3, the active module 1 is provided with an arc-shaped notch on one side, and a cavity is provided at the bottom of the active module 1 toward the arc-shaped notch. A central magnet 11 is fixed in the cavity toward the arc-shaped notch. An outer fixed magnet 12 is fixed on the other side of the magnet 11 away from the arc-shaped gap, and an outer movable magnet 13 is also provided in the cavity. Since the outer movable magnet 13 and the outer fixed magnet 12 are laterally mutually exclusive, there is no external force. In this case, since the three edge magnets are laterally mutually exclusive, when there is no external force, the connection lines between the outer fixed magnet 12, the outer movable magnet 13 and the center magnet 11 are stably distributed at 120°, and the two outer movable magnets 13 The opening angle between them is facing the arc-shaped notch of the active module 1. The outer movable magnet 13 rolls around the central magnet 11 when disturbed by external magnetic force; the bottom of the cavity is made of transparent acrylic hard material, and the position and relative movement of the magnets in the active module 1 can be observed from the outside.

The specific method for fixing the central magnet 11 and the outer fixed magnet 12 in the cavity is through the shaft hole connection method. There is a small cylinder in the cavity, and the central magnet 11 and the outer fixed magnet 12 are annular and are sleeved and fixed in the cavity. On the inner small cylinder, the central magnet 11, the outer fixed magnet 12 and the outer movable magnet 13 are axially magnetized annular magnets with the same shape and brand.

The passive module 2 is provided with several convex corners. In this embodiment, the passive module 2 is a flat regular triangular prism with rounded corners, that is, it has three convex corners. A passive magnet 21 is fixed on each convex corner, so it can receive magnetic force in multiple directions. Specifically, a small cylinder is provided at the convex corner, and the passive magnet 21 is also an annular shape with the same shape and magnetic properties, and is sleeved and fixed on the small cylinder at the convex corner. The central magnet 11, the passive magnet 21, the outer fixed magnet 12 and the outer movable magnet 13 all use φ7 mm×φ4.5 mm×4 mm NdFeB permanent magnets. The height of the passive magnet 21 is consistent with the height of the magnet in the active module 1. , the contours of the passive magnet 21 and the convex corners of the passive module 2 are tangent, making the connection between the moving magnet 21 and the central magnet 11 more sensitive. All ring magnets are axially magnetized and placed "side by side" in a plane perpendicular to the magnetization axis, which means that when two magnets with opposite magnetization directions, i.e. opposite magnetic poles, come together, they attract each other laterally, magnetizing Magnets with the same orientation repel each other.

The bottom of the active module 1 is provided with a rough surface, so that there is a certain amount of friction between the active module 1 and the game platform, which improves the feel and allows the active module 1 to be better controlled to approach the passive module 2 at a constant speed, thereby experiencing tactile feedback of repulsion and suction. 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 are opposite to the magnetic poles of the center magnet 11 . The active module 1 and the passive module 2 have the characteristics of repelling each other at a distance and attracting at a close distance, and there is a critical distance. When the passive magnet 21 and the central magnet 11 are at the critical distance, they are in an unstable equilibrium state. The convex angle matches the shape of the arc-shaped notch on the active module 1 .

As shown in Figure 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 dominates. When the distance d is infinite, the connection between the outer fixed magnet 12 and the central magnet 11 is The angle θ between the vertical lines is 30°.

As shown in Figure 5b, when the distance d between the active module 1 and the passive module 2 is less than the critical distance, the magnetic attraction between the center magnets of the active part and the passive part dominates, and as the distance d becomes smaller, the angle θ become smaller.

As shown in Figure 5c, the passive module 2 is adsorbed on the center magnet 11 by the active module 1, and the passive magnet 21 becomes a new edge magnet. At this time, the included angle θ is 0 degrees.

As shown in Figures 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 gap of the active module 1, and the passive magnet 21 is magnetically attracted to the central magnet 11. The passive magnet 21. The outer fixed magnet 12 and the outer movable magnet 13 are rotationally symmetrical at 90 degrees around the central magnet 11.

Embodiment 2

As another embodiment, the method of using the magnetic interactive toy with switchable magnetic attraction and repulsion proposed in Embodiment 1 is specifically as follows:

Step 1. Plug the obstacle module into the array hole on the surface of the game platform, place several active modules 1 and passive modules 2 on the surface of the game platform, and install plug-ins on the active module 1 and passive module 2 to act as hunters respectively. Modules and prey modules can also be defined as other names according to the game settings to realize the replacement and customization of game characters and carry out multi-player games or multi-hand games. During simultaneous games, the number of active modules 1 and players is no more than the number of passive magnets 21 on the passive module 2.

Step 2: The player controls one or more active modules 1 to approach the passive module 2. The repulsive force formed by the outer sliding magnet 13 on the passive magnet 21 is greater than the attraction force formed by the central magnet 11 on the passive magnet 21, and the passive module 2 is pushed on the plane. Since the magnetic poles of the passive magnets 21 of several passive modules 2 are the same, several passive modules 2 repel each other. When the active module 1 pushes a certain passive module 2, the pushed passive module 2 generates a repulsive force on other passive modules 2. , causing other passive modules 2 to also move. Games like tabletop ice hockey, football, and obstacle course can be played based on this process, that is, the active module 1 is not used to capture the passive module 2, but it is made to move continuously, with impact or movement as the core gameplay.

Step 2 can also be followed by step 3 to form a capturing gameplay. Step 3 is specifically: when the passive module 2 is pushed to the obstacle module or is surrounded and fixed by several active modules 1, further open the arc-shaped gap of the active module 1. Approaching the central magnet 11 , the attraction force between the central magnet 11 and the passive magnet 21 continues to increase until the central magnet 11 and the passive magnet 21 are magnetically attracted to realize the capture of the passive module 2 .

During the interaction process, users can experience different tactile sensations such as instant attraction, sustained push, and strong resistance and repulsion. Compared with other magnetic toys, the present invention pays more attention to the rich and continuous tactile experience during the magnetic interaction process, which is helpful for experiential perception and learning of physical knowledge such as magnetism.

An outer fixed magnet 12 is fixed on the side of the center magnet 11 away from the slide 3.

The central magnet 11, the passive magnet 21, the outer fixed magnet 12 and the outer sliding magnet 13 are provided with red and blue stickers indicating the north and south magnetic poles. Players can slide the slider 4 to observe and perceive the magnetic interaction principle of this toy.

As shown in FIG. 6 , when the slider 4 has not moved the passive magnet 21 to one end of the central magnet 11 , the outer fixed magnet 12 and the outer sliding magnet 13 are rotationally symmetrical about 120° around the central magnet 11 .

As shown in FIG. 7 , when the slider 4 moves the passive magnet 21 to one end of the central magnet 11 , the passive magnet 21 , the outer fixed magnet 12 and the outer sliding magnet 13 become 90° rotationally symmetrical around the central magnet 11 .
