Preferably, the base and the cover body are respectively connected to the two sides of the mounting bracket in an ultrasonic welding manner. When ultrasonic waves act on thermoplastic plastic contact surfaces, tens of thousands of high-frequency vibrations per second will be generated. The high-frequency vibration waves are transmitted to a surface of the mounting bracket, a surface of the base, and a surface of the cover body. A local high temperature may be caused due to a high acoustic resistance at interfaces of the surface of the mounting bracket and the surfaces of the base and cover body. As plastic has poor thermal conductivity, heat cannot be dissipated in time and is accumulated in a welding region. As a result, the interfaces of the surface of the mounting bracket and the surfaces of the base and cover body are quickly melted. Furthermore, a certain pressure is applied. After the action of the ultrasonic waves stops, the pressure is last for several seconds, so that the interfaces are solidified and molded. In this way, the mounting bracket, the base, and the cover body form a whole. The welding purpose is achieved. The welding strength can be close to the strength of an original material. Moreover, welding lines can be reduced. In a case of guaranteeing the connection strength, the product has a more attractive appearance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

First Embodiment

Referring to FIG. 1 to FIG. 12, a magnetic toy includes:

• • a mounting bracket 10, wherein the mounting bracket 10 includes a plurality of clamping members 11; two adjacent clamping members 11 are connected to form the mounting bracket 10;
  • a clamping portion 12 is arranged at an end portion of each of the clamping members 11; a clamping space 13 is formed between the two clamping portions 12 on the two adjacent clamping members 11;
  • a magnetic member 20, wherein the magnetic member 20 is arranged in the clamping space 13, wherein the magnetic member 20 includes an iron tube 21 and a magnet 22; the magnet 22 is arranged in the iron tube 21; two adjacent mounting columns 121 in the clamping space 13 are respectively clamped to two ends of the iron tube 21;
  • a base 301, wherein the base 301 is connected to one side of the mounting bracket 10; and
  • a cover body 302, wherein the cover body 302 is connected to the other side of the mounting bracket 10 and is covered on the base 301;
  • wherein the base 301 and the cover body 302 are both provided with gaps 31; the gaps 31 correspond to the clamping space 13; and when the base 301 and the cover body 302 are connected to the mounting bracket 10, at least part of the iron tube 21 is arranged into the gaps 31.

In this embodiment, the clamping portions 12 are provided with mounting columns 121; the mounting columns 121 are arranged in a manner of facing the mounting space 13; the magnet 22 is rotatably arranged in the iron tube 21; and the two ends of the iron tube 21 respectively sleeve the two adjacent mounting columns 121.

Due to the arrangement of the above structure, during use, the clamping members 11 are connected to one another in sequence to form the mounting bracket 10. Angles between two edges of different types of clamping members 11 are different, so that magnetic toys in different shapes with the mounting brackets 10 can be formed, for example, a triangular magnetic toy, a rectangular attraction toy, a trapezoid attraction toy, or a hexagonal attraction toy. As shown in FIG. 10 to FIG. 12, users have more assembling choices on the magnetic toys in various shapes, which improves the fun of the product. The mounting columns 121 are arranged on the outer sides of the end portions of the clamping members 11. After all the clamping members 11 are connected, the clamping space 13 is formed between two opposite mounting columns 121. The magnet 22 is arranged in the iron tube 21. A first end of the iron tube 21 sleeves the mounting column 121 on one clamping member 11, and a second end of the iron tube 21 sleeves the mounting column 121 on the other clamping member 11. The two clamping members 11 are connected to stably connect the two ends of the iron tube 21 to the two mounting columns 121. When the magnet 22 is arranged in the iron tube 21, the magnet 22 can rotate in the iron tube 21. Under the action of a magnetic force, an orientation of a magnetic pole of the magnet 22 can be automatically adjusted. An N pole of one magnetic toy attracts an S pole of another identical magnetic toy, or an S pole of the magnetic toy attracts an N pole of the another identical magnetic toy, so as to achieve stable connection between the magnetic toys. Meanwhile, the iron tube can shrink magnetic induction lines around the magnet, so that the magnetic induction lines around the magnet are distributed more densely, and the magnetic induction intensity of a surface of the iron tube is improved. When two adjacent iron tubes get close to each other, a magnetic force between the two iron tubes is higher, which further improves the stability of connection of the magnetic toys and improves the use experience of a user. The base 301 and the cover body 302 are respectively connected to two sides of the mounting bracket 10, so that all the clamping members 11 can be fixed and are prevented from being separated from one another, which improves the stability of the product. Furthermore, the base 301, the cover body 302, and the mounting bracket can be in different colors. When the base 301 and the cover body 302 are connected to the two sides of the mounting bracket, edges of the clamping members are exposed between the base 301 and the cover body 302 to form a sandwich shape. There may be more colors matching each other, so that the product has a more attractive appearance and richer colors. Preferably, the base 301 and the cover body 302 are respectively connected to the two sides of the mounting bracket 10 in an ultrasonic welding manner. When ultrasonic waves act on thermoplastic plastic contact surfaces, tens of thousands of high-frequency vibrations per second will be generated. The high-frequency vibration waves are transmitted to a surface of the mounting bracket, a surface of the base 301, and a surface of the cover body 302. A local high temperature may be caused due to a high acoustic resistance at interfaces of the surface of the mounting bracket and the surfaces of the base 301 and cover body 302. As plastic has poor thermal conductivity, heat cannot be dissipated in time and is accumulated in a welding region. As a result, the interfaces of the surface of the mounting bracket and the surfaces of the base 301 and cover body 302 are quickly melted. Furthermore, a certain pressure is applied. After the action of the ultrasonic waves stops, the pressure is last for several seconds, so that the interfaces are solidified and molded. In this way, the mounting bracket, the base 301, and the cover body 302 form a whole. The welding purpose is achieved. The welding strength can be close to the strength of an original material. Moreover, welding lines can be reduced. In a case of guaranteeing the connection strength, the product has a more attractive appearance.

Due to the arrangement of the above structure, the base 301 and the cover body 302 are both provided with the gaps 31. When the base 301 and the cover body 302 are connected to the mounting bracket 10, the gaps 31 correspond to the clamping space 13. The iron tube 21 is exposed in the gaps 31, so that the magnetic members 20 of different magnetic toys are directly connected, which improves the magnetic force of the product and achieves high magnetic strength. The magnetic connection between two magnetic toys is more stable, and the use experience of a user is improved.

In this embodiment, abutment platforms 122 are arranged at joints of the mounting columns 121 and the clamping members 11; and when the iron tube 21 sleeves the mounting columns 121, end portions of the iron tube 21 abut against the abutment platforms 122. Due to the arrangement of the above structure, during use, the iron tube 21 sleeves the mounting columns 121 until the end portions of the iron tube 21 abut against the abutment platforms 122, and at this time, the iron tube 21 is at a mounting position. The abutment platforms can effectively restrict a sleeving depth of the iron tube 21 and restrict the position of the iron tube 21, thereby preventing damage to the iron tube 21 or the mounting columns 121 caused by improper mounting, and increasing the yield of the product.

In this embodiment, a diameter of a connecting end of each of the mounting columns 121 is greater than a diameter of a free end of the mounting column 121. Due to the arrangement of the above structure, a diameter of each of the mounting columns 121 gradually increases from its free end to its connecting end. To connect the mounting columns 121 to the iron tube 21, a user is allowed to plug the mounting columns 121 into the iron tube 21 more easily according to the relatively small diameters of the free ends of the mounting columns 121, so that the assembling efficiency is improved, and the yield of the product is increased.

In this embodiment, a guide cambered surface 123 is arranged at a free end of each of the mounting columns 121. Due to the arrangement of the above structure, to connect the mounting columns 121 to the iron tube 21, the guide cambered surfaces 123 are in contact with an inner wall of the iron tube 21, which further facilitates a user to plug the mounting columns 121 into the iron tube 21, and improves the production efficiency.

In this embodiment, the magnet 22 is columnar; a diameter of the magnet 22 matches an inner diameter of the iron tube 21; an axial direction of the magnet 22 matches an axial direction of the iron tube 21; and the magnet 22 rotates in the iron tube around the axial direction of the magnet. Due to the arrangement of the above structure, the columnar magnet 22 rotates in the iron tube 21 more easily. During use, the axial direction of the magnet 22 is basically parallel to the axial direction of the iron tube 21, and the diameter of the magnet 22 is slightly less than the inner diameter of the iron tube 21. Under the action of the magnetic force, the magnet 22 rotates, so that a direction of a magnetic pole of the magnet 22 matches a direction of an external magnetic field, which achieves free connection between magnetic blocks more easily and improves the use experience of a user.

In this embodiment, a connecting block 111 is arranged at a first end of each of the clamping members 11; a connecting slot 112 is formed in a second end of the clamping member 11; and the connecting block 111 on one of the clamping members 11 is plugged into the connecting slot 112 on the neighboring clamping member 11. Due to the arrangement of the above structure, the connecting block 111 on one clamping member 11 is connected to the connecting slot 112 on another clamping member 11, so that the two clamping members 11 are connected to each other, which can facilitate the assembling and connection of the clamping members and improve the assembling efficiency.

In this embodiment, one side of an axis of the magnet 22 is an S pole, and the other side of the axis of the magnet 22 is an N pole. Due to the arrangement of the above structure, the magnet 22 rotates around the axis to adjust orientations of magnetic poles. When two magnetic toys are connected to each other, under the action of the magnetic force, the magnets 22 rotate around the axes, so that the orientations of the magnetic poles of the magnets 22 can be automatically adjusted. An N pole of one magnetic toy and an S pole of the other identical magnetic toy attract together, or an S pole of the magnetic toy and an N pole of the other identical magnetic toy attract together, so as to achieve stable connection between the magnetic toys.

In this embodiment, a transverse length of the iron tube 21 is greater than a transverse length of the magnet 22; and a space exists between an end portion of the magnet 22 and a free end of each of the mounting columns 121. Due to the arrangement of the above structure, when the magnet 22 rotates around the axis, the space existing between the end portion of the magnet 22 and the free end of each of the mounting columns 121 can eliminate a friction force between the magnet 22 and the mounting column 121, so that the magnet 22 can rotate more easily around the axis, which conveniently adjusts the magnetic poles and facilitates the stable connection between the magnetic toys.

In this embodiment, a mounting convex block 32 is arranged on an inner side of the cover body 302; a mounting groove 33 is formed in an inner side of the base 301; and when the cover body 302 is connected to the other side of the mounting bracket 10 and is covered on the base 301, the mounting convex block 32 is plugged into the mounting groove 33. Due to the arrangement of the above structure, the base 301 and the cover body 302 are respectively connected to the two sides of the mounting bracket 10. The mounting convex block 32 is connected into the mounting groove 33. The mounting convex block 32 is stably connected to the mounting groove 33 in an ultrasonic welding manner, which improves the stability of the product and fixes all the clamping members 11. Furthermore, the base 301 and the cover body 302 can be transparent or semi-transparent, so that the mounting bracket 10 can be observed through the base 301 and the cover body 302, and the product is more attractive.

In this embodiment, a connecting portion 14 is arranged at a position, close to each of the mounting columns 121, of each of the clamping members 11 in a protruding manner; abutment blocks 34 are arranged on an inner side of the cover body 302 and/or an inner side of the base 301; and when the cover body 302 is connected to the other side of the mounting bracket 10 and is covered on the base 301, the abutment blocks 34 abut against an end surface of the connecting portion 14. Due to the arrangement of the above structure, when the base 301 and the cover body 302 are connected to the mounting bracket 10, the abutment blocks 34 abut against the end surface of the connecting portion 14, so that the base 301 and the cover body 302 are more stably connected to the mounting bracket 10, and positioning between the base 301, the cover body 302, and the mounting bracket 10 is achieved. The mounting is facilitated, and the stability of the product is improved.

In this embodiment, a connecting board 15 is arranged at an edge of each of the clamping members 11 in a protruding manner; and when the cover body 302 is connected to the other side of the mounting bracket 10 and is covered on the base 301, an outer edge of the cover body 302 and/or an outer edge of the base 301 abut against and are connected to an inner side of the connecting board 15. Due to the arrangement of the above structure, the outer edge of the cover body 302 and the outer edge of the base 301 abut against and are connected to the inner side of the connecting board 15, and the outer edge of the base 301 and the outer edge of the cover body 302 are connected to the inner side of the connecting board 15 in an ultrasonic welding manner, so that welding lines can be reduced, and stable connection can be achieved.

In this embodiment, connecting edges 35 are arranged at an edge of an outer surface of the cover body 302 and/or an edge of an outer surface of the base 301; and at least part of the connecting edges 35 abut against and are connected to an inner side of the connecting board 15. Due to the arrangement of the above structure, the connecting edges abut against the inner side of the connecting board 15, and the connecting edges 35 can be connected to the inner side of the connecting board 15 in an ultrasonic welding manner. The connecting edges 35 can improve the intensities of the base 301 and the cover body 302, which further improves the intensity of the product.

In this embodiment, reinforcing ribs 36 are arranged in the middle of a surface of the cover body 302 and/or in the middle of a surface of the base 301 in a protruding manner. Due to the arrangement of the above structure, the reinforcing ribs 36 are arranged in the middles of the base 301 and the cover body 302 in the protruding manner, so that the intensity of the product can be improved. Furthermore, the reinforcing ribs 36 in the middles of inner surfaces of the base 301 and the cover body 302 can be connected to a surface of the mounting bracket 10 in an ultrasonic welding manner or the like, which further improves the intensity of the product.

In this embodiment, connecting cambered surfaces 37 are arranged at an edge of an inner side of the cover body 302 and/or an edge of an inner side of the base 301; and the two connecting cambered surfaces 37 are connected to form a central through hole 40. Due to the arrangement of the above structure, the two connecting cambered surfaces 37 are connected to each other. The central through hole 40 is formed between inner surfaces of the connecting cambered surfaces 37, so that a hollowed magnetic toy can be formed. Magnetic toys with frames in various shapes are formed according to differences between the shapes of the clamping members 11 and the shapes of the base 301 and cover body 302.

In this embodiment, an arc-shaped transition surface 16 is arranged on an outer edge of each of the clamping members 11; and the arc-shaped transition surface 16 matches an outer surface of the iron tube 21. Due to the arrangement of the above structure, a radian of the arc-shaped transition surface 16 is basically consistent with a radian of the outer surface of the iron tube 21. When two magnetic toys magnetically attract each other, the arc-shaped transition surfaces of the two magnetic toys abut against each other, which further improves the stability of the product and facilitates a user to assemble the magnetic toys.

In this embodiment, a transition curved surface 151 is arranged at an edge of the connecting board 15; and the transition curved surface 151 is used to allow the connecting edges 35 to slide along the transition curved surface 151.

In this way, the base 301 and the cover body 302 are quickly positioned on the mounting bracket, which facilitates a user to mount the base 301 and the cover body 302 and improves the production efficiency of the product.

In this embodiment, each of the clamping members 11 is a plastic clamping member.

Furthermore, the magnetic attraction member includes the iron tube and the magnet located in the iron tube, so that the transverse length of the iron tube can be set to be greater than that of the magnet. Specifically, the transverse length of the iron tube can be set to be twice that of the magnet, and the first clamping end and the second clamping end can be inserted into two ends of the iron tube, so that a magnetic attraction contact area between the magnetic attraction toys can be multiplied, and the magnet can still be fixed in a center position of the iron tube to provide a stronger and more stable magnetic attraction force, thus enhancing the second stage of magnetic force. In addition, the iron tube wrapping around the magnet makes magnetic induction lines around the magnet distributed intensively, so that the magnetic induction intensity around a surface of the magnetic attraction body becomes stronger, thus enhancing the third stage of magnetic force. A surface contact magnetic force of the magnetic attraction toy is enhanced by superposition of the enhancement of the three stages of magnetic forces, so that a user can put out a more three-dimensional, complicated and stable model using the magnetic attraction building blocks without increasing the cost for a strong magnet, and children's imagination can be developed more fully, which greatly increases the fun of experience of children. In addition, the first clamping piece and the second clamping piece are respectively clamped to two ends of the iron tube. On the one hand, the ribs welded with the first clamping piece and the second clamping piece are arranged on the base and the cover body, so that the number of welding lines is greatly increased, and a decrease in the quality of a product caused by difficulty in finding lack of weld is prevented. On the other hand, the thickness of an entire plastic building block is greatly increased, so that the overall torque resistance and tensile strength are greatly improved in order that children think a toy building block body cannot be broken with bare hands. A safety threat caused by the following fact can be effectively avoided: when playing the toy, a child swallows the magnet carelessly since a toy shell is broken. The safety of the magnetic attraction toy is then improved. Further, every country does not allow strong magnets to be exposed in children's products. The magnet is fixed in the iron tube. On the one hand, this regulation is met, and on the other hand, the magnetic attraction toys can be in direct contact through the surfaces of the iron tubes. Meanwhile, magnetic fields around the magnet are also strengthened.

In this embodiment, the base and the cover body can be provided with triangular, square, hexagonal, pentagonal, rhombus-shaped, trapezoid, fan-shaped or semicircular cross sections or cross sections in other shapes. When the base and the cover body can be provided with square cross sections, there are four magnetic attraction members and four mounting frames, which are respectively arranged on an upper side, lower side, left side and right side of the square base.

The first connection end 421 is a groove, and the second connection end 431 is a convex block matched with the groove 421. When the first clamping end 422 is plugged to the first opening 311, and the second clamping end 432 is plugged to the second opening 312, the convex block is connected with the groove. Specifically, the first clamping piece 42 and the second clamping piece 43 are both plastic clamping pieces. One end of the magnet 32 is an N pole, and the other end of the magnet 32 is an S pole. By means of the above structure, the magnetic attraction toy is simple in structure, reasonable in design and stable in connection, so that connection between the magnetic attraction member and the mounting frame is effectively achieved. Further, by means of the cooperation between the groove and the convex block, a position offset between the first clamping piece and the second clamping piece can be effectively prevented, so that the first clamping end of the first clamping piece and the second clamping end of the second clamping piece stably clamp the iron tube. Specifically, one end of the magnet is an N pole, and the other end of the magnet is an S pole, so that the N pole of the magnetic attraction toy can be easily guided to attract the S pole of another same magnetic attraction toy, and the S pole of the magnetic attraction toy can be guided to attract the N pole of another same magnetic attraction toy, so as to achieve stable connection between the magnetic attraction toys and facilitate the user to build a three-dimensional model. Further, the first clamping end 422 has a narrow front portion and a wide rear portion, and the second clamping end 432 has a narrow front portion and a wide rear portion, so that a first guide portion 423 is formed at a front end of the first clamping end, and a second guide portion 433 is formed at a front end of the second clamping end, and the first clamping end and the second clamping end can be inserted into the two ends of the iron tube to clamp the iron tube.

The locating holes 41 include a first locating hole unit 411 formed in the first clamping piece 42 and a second locating hole unit 412 formed in the second clamping piece 43. When the first clamping end 422 is plugged to the first opening 311 and the second clamping end 432 is plugged to the second opening 312, and when the first locating hole unit 411 sleeves the first locating pillar unit 111 and the second locating hole unit 412 sleeves the second locating pillar unit 112, the cover body 2 is covered on the base 1 to stop the first locating pillar unit 111 in the first locating hole unit 411 and stop the second locating pillar unit 112 in the second locating hole unit 412, so as to stop the mounting frame 4 in the base 1. The magnetic attraction member 3 is stopped in the limiting gap 5. The cover body 2 is provided with a stop edge 21. When the cover body 2 is covered on the base 1, the stop edge 21 abuts against the first locating pillar unit 111 and the second locating pillar unit 112 to stop the first locating pillar unit 111 in the first locating hole unit 411 and stop the second locating pillar unit 112 in the second locating hole unit 412, so that the magnetic attraction member 3 is stopped in the limiting gap 5. Specifically, a raised first rib 12 is also arranged on the base 1. When the first clamping end 422 is plugged to the first opening 311 and the second clamping end 432 is plugged to the second opening 312, and when the first locating hole unit 411 sleeves the first locating pillar unit 111 and the second locating hole unit 412 sleeves the second locating pillar unit 112, the first clamping piece 42 and the second clamping piece 43 are both connected with the first rib 12 by means of ultrasonic line welding. Further, a raised second rib 22 is arranged on the cover body 2. When the first locating hole unit 411 sleeves the first locating pillar unit 111 and the second locating hole unit 412 sleeves the second locating pillar unit 112, and when the cover body 2 is covered on the base 1, the first clamping piece 42 and the second clamping piece 43 are both connected with the second rib 22 by means of ultrasonic line welding. Much further, when the cover body is covered on the base, a first stop edge abuts against a first locating pillar and a second locating pillar to stop and press the first clamping piece and the second clamping piece to the base, so that the magnetic attraction member is stopped in the limiting gap. By means of the above structure, connection among the magnetic attraction member, the mounting frame and the base is effectively achieved. The mounting frame is stably fixed on the base by connecting the locating holes of the mounting frame to the locating pillars on the base in a sleeving manner. The first clamping piece and the second clamping piece are both connected with the first rib by means of the ultrasonic line welding, and the first clamping piece and the second clamping piece are both connected with the second rib by means of the ultrasonic line welding, so that the first clamping piece and the second clamping piece are stably mounted between the cover body and the base; the first clamping piece and the second clamping piece can be effectively prevented from being separated from the locating pillars, thus preventing the magnetic attraction member clamped by the first clamping piece and the second clamping piece from being separated from the limiting gap; and the situation that a child carelessly swallows the loosened magnetic attraction member is prevented, thus further improving the safety and stability of the magnetic attraction toy. Furthermore, a three-dimensional model built using the magnetic attraction toy is more stable. Further, by means of adding the first rib and the second rib inside, the welding area is enlarged, the process risk of lack of weld is effectively avoided, the quality of a product is improved, and the reject ratio of products is reduced.
