Description

Technical Field

[0001] This utility model relates to the field of assembly toys, specifically to a magnetic assembly toy with interchangeable features. Background Technology

[0002] With the increasing diversity of children's toys and the development of the times, the toy industry needs to continuously innovate new technologies and ways to play, and actively launch new and innovative toy products to satisfy children's curiosity and happy childhood.

[0003] Traditional assembly toys mainly use interference fits between parts, ball heads and sockets, C-shaped buckles, mushroom heads and other structures to achieve assembly. However, they have problems such as a large number of parts, easy damage to the appearance, and inconvenience for children to operate, making it difficult to quickly achieve fun.

[0004] Traditional magnetic toys primarily use multiple identical magnetic blocks to attract each other and form a block shape, which differs significantly from the intended design. Alternatively, they may have a flat pattern on one surface of a magnetic block, with the patterns from multiple blocks combining to create a complete image. However, neither of these types of magnetic toys is novel or innovative, and they fail to satisfy children's curiosity. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems and shortcomings by providing a magnetic assembly toy with interchangeable features, effectively solving the problems of existing assembly toys being difficult to assemble, having large differences in appearance, and being unable to change the character's form.

[0006] The technical solution of this utility model is implemented as follows: The present invention discloses a magnetic assembly toy with interchangeable features, comprising: a central magnetic block having multiple magnetic surfaces; multiple shaped patches having partial shaped features and at least one adsorption surface, the adsorption surface being magnetically attracted and attached to one of the magnetic surfaces of the central magnetic block; after the multiple shaped patches are magnetically attracted and attached to the magnetic surfaces of the central magnetic block according to a set position and direction, the partial shaped features of the multiple shaped patches together form a complete shaped feature, or the partial shaped features of the multiple shaped patches together with the central magnetic block form a complete shaped feature.

[0007] In some embodiments, the shape of the central magnetic block is a cube, rectangle, triangle, cone, or irregular polyhedron.

[0008] In some embodiments, each magnetic surface of the central magnetic block is provided with a magnet on its inner wall, and the adsorption surface of the shaped patch is provided with an iron sheet or a magnetic sheet.

[0009] Furthermore, the central magnetic block includes a housing and a cover, and the inner wall of the housing is provided with a magnet mounting position corresponding to the middle position of the magnetic surface, and the magnet is installed in the magnet mounting position.

[0010] In some embodiments, at least one of the multiple shaping patches of the same complete shape includes at least one replacement patch. The replacement patch is a partial shape with the same shape as the shaping patch but a different form. The shape of the complete shape is changed by replacing the shaping patch with the replacement patch.

[0011] In some embodiments, the magnetic surface of the central magnetic block has planar patterns with the same part shape but different shapes. The number of shape patches is one less than the number of magnetic surfaces. After all the shape patches are magnetically attracted and attached to the magnetic surfaces, the planar pattern of one of the magnetic surfaces is exposed, so that the partial shapes of the multiple shape patches together with the exposed planar pattern of the central magnetic block form a complete shape.

[0012] In some embodiments, the magnetic surface of the central magnetic block is a plane, a convex surface, or a concave surface, and the adsorption surface of the shaped patch is a plane, a concave surface, or a convex surface.

[0013] In some embodiments, the complete model is a human doll, animal, vehicle, or scene model.

[0014] In some embodiments, the shaped patch has two adsorption surfaces, and a portion of the shaped patch is a hinge shape. The two adsorption surfaces are magnetically attracted and attached to one of the magnetic surfaces of the two central magnetic blocks to enable the two central magnetic blocks to rotate through the hinge.

[0015] In some embodiments, when the central magnetic block is a cube or rectangle and the complete shape is a humanoid doll, the plurality of shaping patches include a head shaping patch, a back shaping patch, a left hand shaping patch, a right hand shaping patch, and foot shaping patches. A portion of the head shaping patch represents the head of the humanoid doll; a portion of the back shaping patch represents the back of the humanoid doll; a portion of the left hand shaping patch represents the left hand of the humanoid doll; a portion of the right hand shaping patch represents the right hand of the humanoid doll; and a portion of the foot shaping patches represents the feet of the humanoid doll. The six magnetic surfaces of the central magnetic block each have six different facial patterns. After the five shaping patches are magnetically attracted and attached to the five magnetic surfaces of the central magnetic block according to a set position and direction, the partial shapes of the five shaping patches, together with the remaining exposed facial patterns, form a complete humanoid doll shape.

[0016] The beneficial effects of this utility model are: (1) Since the central magnetic block is used as the connecting base and multiple shaped patches are designed as three-dimensional partial shapes, and then the adsorption surface of the shaped patch is magnetically attached to the magnetic surface of the central magnetic block to form a complete three-dimensional shape, the assembly of this utility model is simpler and faster than traditional assembly toys, and the number of parts is smaller, which is conducive to children to quickly realize the fun; at the same time, compared with traditional magnetic toys, this utility model has a more three-dimensional effect, no longer a simple flat pattern, and the model after assembly has a stronger simulation effect, which is highly innovative and can satisfy children's curiosity.

[0017] (2) Since each magnetic surface of the central magnetic block can be set with a planar pattern, when the shape patch is magnetically attracted to the central magnetic block and retains an exposed planar pattern of the magnetic surface, these shape patches and the exposed planar pattern can be combined to form a complete shape. This design can further reduce the number of shape patches and achieve rapid assembly with fewer parts; moreover, different exposed planar patterns can achieve changes in shape and are more interesting.

[0018] (3) Since the central magnetic block can be reused, different shapes can be interchanged and matched to assemble various shapes. The assembly is flexible and diverse, and a variety of different ways to play can be achieved.

[0019] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be understood that the terms "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish descriptive features, without any order or emphasis.

[0024] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "fitting," "connected," "linked," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The magnetic assembly toy of this invention, which allows for arbitrary interchangeability, is described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, this utility model relates to a magnetic assembly toy with interchangeable shapes, including a central magnetic block 1 and multiple shaped patches 2. The central magnetic block 1 has multiple magnetic surfaces 10, and each shaped patch 2 has a partial shaped body 21 and at least one adsorption surface 22. The adsorption surface 22 is magnetically attracted and adhered to one of the magnetic surfaces 10 of the central magnetic block 1. After the multiple shaped patches 2 are magnetically attracted and adhered to the magnetic surfaces 10 of the central magnetic block 1 according to a set position and direction, the partial shaped bodies 21 of the multiple shaped patches 2 together form a complete shape, or the partial shaped bodies 21 of the multiple shaped patches 2 together with the central magnetic block 1 form a complete shape. Therefore, compared with traditional assembly toys, the assembly of this utility model is simpler and faster, and the number of parts is smaller, allowing children to quickly enjoy the fun. At the same time, compared with traditional magnetic toys, this utility model has a more three-dimensional effect, no longer a simple two-dimensional shape, and the assembled shape has a stronger simulation effect, is highly innovative, and can satisfy children's curiosity.

[0028] Understandably, the partial shape 21 on the shape patch 2 is a three-dimensional shape, rather than a two-dimensional image of the pattern 15. For example... Figure 1 The shape patch 2 on the left is a hand shape patch. Its actual partial shape 21 is a three-dimensional shape of a right hand. Therefore, the assembled toy is a three-dimensional shape of a human doll, rather than a complete flat pattern 15 after the assembly of existing traditional magnetic toys.

[0029] Understandably, the shape of the central magnetic block 1 of this invention can be diverse. For example, the shape of the central magnetic block 1 can be a cube, rectangle, triangle, cone, or irregular polyhedron; it can also be a trapezoid, a multi-curved irregular shape, a polygon, etc. Furthermore, each face of the central magnetic block 1 can be a magnetic face 10; or some faces can be non-magnetic faces 10. For example, when the central magnetic block 1 is a cone, it has five faces: four triangular faces and a rectangular face at the bottom. In this case, all five faces can be designed as magnetic faces 10, or only four triangular faces can be designed as magnetic faces 10, while the bottom rectangular face is a non-magnetic face 10, serving as the placement base.

[0030] The decorative patch 2 has at least one adsorption surface 22, meaning it can have only one adsorption surface 22 or two or more adsorption surfaces 22. For example, if the decorative patch 2 has two adsorption surfaces 22, and the partial decorative body 21 of the decorative patch 2 is a hinged body, then after the two adsorption surfaces 22 are magnetically attracted and attached to one of the magnetic surfaces 10 of the two central magnetic blocks 1, the two central magnetic blocks 1 can rotate relative to each other through the hinge. Furthermore, for example, the shape patch 2 with two adsorption surfaces 22 and a hinge can be designed to simulate the connection between two train carriages and the relative ends of these two carriages. The two central magnetic blocks 1 are rectangular. After the two adsorption surfaces 22 of the shape patch 2 are magnetically attached to the two central magnetic blocks 1 respectively, other shape patches 2 with a single adsorption surface 22, including those shaped like the top of the carriage, the front of the carriage, the rear of the carriage, and the wheels at the bottom of the carriage, are magnetically attached to the other magnetic surfaces 10 of the two central magnetic blocks 1. In this way, these shape patches 2 and the two central magnetic blocks 1 can be combined to form a complete train shape. At the same time, the train can move by the wheels of the shape patch 2 shaped like the wheels at the bottom of the carriage. Therefore, the simulation effect is strong and the gameplay is novel and interesting. As can be seen from the above, this utility model is not limited to assembling only one central magnetic block 1 and multiple shaped patches 2. As needed, it can also be assembled with two or more central magnetic blocks 1 and multiple shaped patches 2. Therefore, the assembly is flexible and diverse, and has a high degree of playability.

[0031] In this invention, each magnetic surface 10 of the central magnetic block 1 has a magnet 14 on its inner wall. Preferably, the magnet 14 is positioned in the center of each magnetic surface 10. The adsorption surface 22 of the shaped patch 2 has an iron sheet 23 or a magnetic sheet to facilitate adsorption with the magnet 14 of the central magnetic block 1. Preferably, an iron sheet 23 is used, which reduces cost and eliminates the need to distinguish the magnetic pole directions of the magnetic sheet and the magnet 14. The iron sheet 23 can be exposed on the surface of the adsorption surface 22 and mounted on it by adhesive or other embedding methods, or it can be... Figure 4The embodiment shown in this embodiment is that the iron sheet 23 is wrapped inside the shaped patch 2 and placed near the adsorption surface 22, and the processing method can be injection molding.

[0032] The magnet 14 of the central magnetic block 1 can be installed in the following manner: Figure 3 In the embodiment shown, the central magnetic block 1 includes a housing 11 and a cover 12. The inner wall of the housing 11 is provided with a magnet mounting position at the middle position corresponding to the magnetic surface 10. Specifically, the inner walls around the housing 11 are provided with rectangular magnet mounting positions 111, and the inner wall of the bottom surface of the housing 11 is provided with a cylindrical magnet mounting position 112. This embodiment also includes a sleeve post 13. The bottom of the sleeve post 13 can extend into the cylindrical magnet mounting position 112. The top of the sleeve post 13 is provided with a cavity 131 for placing a magnet 14. After the cover 12 is closed with the housing 11, the cover 12 blocks the opening end of the cavity 131, thereby preventing the magnet 14 placed in the cavity 131 from falling out. The opening end of the rectangular magnet mounting position 111 faces the opening end of the housing 11. Simultaneously, insertion plates 121 are provided on the inner surface of the cover 12 near the four edges aligned with the rectangular magnet mounting position 111. When the cover 12 is closed to the housing 11, the insertion plates 121 extend into the rectangular magnet mounting position 111, thereby limiting the vertical movement of the magnet 14 placed in the rectangular magnet mounting position 111 and preventing excessive movement of the magnet 14 from affecting its normal adsorption function. Alternatively, the magnet 14 can be injection molded and placed inside the central magnetic block 1.

[0033] When used as a set, this utility model of a magnetic assembly toy can consist of a central magnetic block 1 paired with more than one magnetic surface 10 of the central magnetic block 1 in the number of modeling patches 2. For example, the central magnetic block 1 is a cube with six magnetic surfaces 10, while the modeling patches 2 can be six or more, such as seven, eight, or nine. Six of the modeling patches 2 are magnetically attracted and attached to the six magnetic surfaces 10 of the central magnetic block 1 to form a complete model. The remaining modeling patches 2 can be replaced with one or more of the six modeling patches 2 to change the appearance of the complete model. Specifically, for example, six decorative patches 2 are magnetically attached to the six magnetic surfaces 10 of the central magnetic block 1 to form a complete humanoid doll. The doll's two arms are angled downwards and it is not holding any weapons. Two more decorative patches 2 remain: a left-hand decorative patch 203 and a right-hand decorative patch 204 with arms raised upwards, and the right-hand decorative patch 204 holding a spear. By removing the two original decorative patches 2 with the arms pointing downwards and replacing them with the remaining left-hand and right-hand decorative patches 203 and 204, the doll's shape changes from its original angled arms to one where the right hand holds a spear and both arms are raised upwards. This simple and quick replacement of the decorative patches 2 allows for shape changes and adds a lot of fun. Of course, there can also be two or more right-hand shaped patches 204. These right-hand shaped patches 204 have the same right-hand part shape, but their shapes are different. Some are raised, some are stretched out, and some are bent. By replacing the right-hand shaped patches 204 with different shapes, the shape of the human-shaped doll can also be changed.

[0034] When used with this magnetic assembly toy, it can also consist of a central magnetic block 1 paired with fewer magnetic surfaces 10 than the central magnetic block 1. For example, the central magnetic block 1 is a cube with six magnetic surfaces 10, while the modeling patches 2 can be five. These five modeling patches 2 are magnetically attracted and attached to five designated magnetic surfaces 10 of the central magnetic block 1, forming a complete model. The remaining magnetic surface 10 serves as the toy's base, allowing it to be placed on a table or countertop. Alternatively, one magnetic surface 10 can be designed with a planar pattern 15, and then the five modeling patches 2 are magnetically attracted and attached to the five unpatterned magnetic surfaces 10 of the central magnetic block 1, allowing the partial modeling 21 of these five modeling patches 2, along with the planar pattern 15, to form a complete model. Figure 1 As shown, Figure 1The planar pattern 15 is a face pattern, and the five shape patches 2 include a head shape patch 201, a back shape patch 202, a left hand shape patch 203, a right hand shape patch 204, and a foot shape patch 205. The partial shape 21 of the head shape patch 201 is the head shape of the human-shaped doll, the partial shape 21 of the back shape patch 202 is the back shape of the human-shaped doll, the partial shape 21 of the left hand shape patch 203 is the left hand shape of the human-shaped doll, the partial shape 21 of the right hand shape patch 204 is the right hand shape of the human-shaped doll, and the partial shape 21 of the foot shape patch 205 is the foot shape of the human-shaped doll. After the five shape patches 2 are magnetically attracted and attached to the five unpatterned magnetic surfaces 10 of the central magnetic block 1 according to the set position and direction, the partial shape 21 of the five shape patches 2 together with the face pattern form a complete human-shaped doll.

[0035] Furthermore, in order to achieve assembly and shape transformation with fewer parts, such as Figure 2 As shown, the central magnetic block 1 in this embodiment is a cube, and each of its six magnetic surfaces 10 has a face pattern. The six face patterns are different, such as a closed-mouth smile, a wide-mouth laugh, a sad pout, etc. The five shape stickers 2 include a head shape sticker 201, a back shape sticker 202, a left hand shape sticker 203, a right hand shape sticker 204, and two foot shape stickers 205. When the adsorption surfaces 22 of these five shape stickers 2 are magnetically attracted and attached to five of the magnetic surfaces 10 of the central magnetic block 1 according to the set position and direction, and the closed-mouth smile face pattern 151 is exposed, then they together form a smiling humanoid doll shape, while the other five face patterns are covered and cannot be seen due to the magnetic attachment of the shape stickers 2. When you need to change the expression to a sad, pouting face, you can rearrange the positions of the five decorative patches 2, exposing the facial pattern 152 of the sad, pouting expression, while the other five magnetic surfaces 10 adhere to the decorative patches 2. This will allow the doll to change into a sad expression. Figure 5 As shown. With this design, a central magnetic block 1 plus five shape pieces 2 can achieve six different shapes, enabling rapid assembly and diverse shape changes with fewer parts, making it more fun and cheaper.

[0036] This utility model Figures 1 to 6The magnetic surfaces 10 of the central magnetic block 1 shown are all planar, but they can also be curved, such as a convex surface protruding outwards or a concave surface concave inwards. Correspondingly, if the magnetic surface 10 is planar, the adsorption surface 22 of the decorative patch 2 is also planar; if the magnetic surface 10 is a convex surface, the adsorption surface 22 of the decorative patch 2 is concave; and if the magnetic surface 10 is concave, the adsorption surface 22 of the decorative patch 2 is convex. This design ensures a more secure connection between the decorative patch 2 and the central magnetic block 1. Of course, the magnetic surface 10 can also be other shapes.

[0037] The partial shape 21 of the shape patch 2 of this utility model can be designed into various shapes, so that the complete shape after assembly can be various imitations, such as human-shaped dolls. Figure 1 or Figure 5 As shown; a complete model can also be a vehicle, such as a train or a tank; a complete model can also be an animal, such as a tiger or a rabbit; a complete model can also be a scene model, such as a house or a rockery; it can also imitate weapons, plants, daily necessities, household appliances, etc.

[0038] The following is a detailed description of specific embodiments.

[0039] Example 1: like Figure 1 , Figure 2 and Figure 5 As shown, this embodiment of the magnetic assembly toy with arbitrary interchangeability includes a central magnetic block 1 and five model patches 2. The central magnetic block 1 is a cube with six magnetic surfaces 10, each of which has a face pattern. The six face patterns are all different. The five model patches 2 include a head model patch 201, a back model patch 202, a left hand model patch 203, a right hand model patch 204, and two foot model patches 205. The partial model 21 of the head model patch 201 is the top of the head and the wings located on both sides of the top of the head. The partial model 21 of the back model patch 202 is a pair of outwardly protruding tail wings. The partial model 21 of the left hand model patch 203 is the left hand shape of the human-shaped doll. The partial model 21 of the right hand model patch 204 is the right hand shape of the human-shaped doll. The partial model 21 of the two foot model patches 205 is the two feet shape of the human-shaped doll. The five decorative patches 2 have the same size adsorption surface 22 as the magnetic surface 10, and are all planar. When the adsorption surfaces 22 of these five decorative patches 2 are magnetically attracted and attached to five of the magnetic surfaces 10 of the central magnetic block 1 according to the set positions and directions, and the facial patterns of the closed-mouth smiling expression are exposed, they together form a smiling humanoid doll shape. The other five facial patterns are obscured and cannot be seen due to the magnetic attachment of the decorative patches 2. Figure 1 As shown. When it is necessary to change the expression to a sad, pouting face, the positions of the five shaping patches 2 can be changed so that the facial pattern of the sad, pouting expression is exposed, while the other five magnetic surfaces 10 are attached to the shaping patches 2. Then the doll can change into a sad expression, as shown. Figure 5 As shown.

[0040] Since each magnetic surface 10 of the central magnetic block 1 can be set with a planar pattern 15, when the shape patch 2 is magnetically attracted to the central magnetic block 1 and retains an exposed planar pattern 15 on the magnetic surface 10, these shape patches 2 and the exposed planar pattern 15 can together form a complete shape. This design can further reduce the number of shape patches 2, achieving rapid assembly with fewer parts; moreover, choosing different exposed planar patterns 15 can achieve changes in shape, which is very interesting.

[0041] Example 2: like Figure 6 As shown, this embodiment of the magnetic assembly toy with interchangeable shapes includes a central magnetic block 1 and seven model stickers 2. The central magnetic block 1 is a cube with six magnetic faces 10. The seven model stickers 2 include a head sticker 201, two face stickers 206, a back sticker 202, a left hand sticker 203, a right hand sticker 204, and a foot sticker 205. The two face stickers 206 have the same face shape, but their expressions are different: one is a closed-mouth smile, and the other is a sad pout. When the six decorative stickers 2—the head sticker 201, the smiling face sticker 206, the back sticker 202, the left hand sticker 203, the right hand sticker 204, and the feet sticker 205—are magnetically attached to the six magnetic surfaces 10 of the central magnetic block 1 according to their set positions and directions, they together form a smiling humanoid doll. To change the expression to a sad, pouting one, simply detach the smiling face sticker 206 from the central magnetic block 1 and attach the sad, pouting face sticker 206 to it, thus transforming the doll into a sad expression.
