Abstract
Description
Technical Field
[0001] This invention relates to the field of toys, and in particular to a connection structure for toys. Background Technology
[0002] Educational toys are important companions in children's growth process. They can help children develop their intelligence and improve their hands-on and thinking abilities while playing. Interesting educational toys are effective tools to help children understand the world and come into contact with and learn about all things new and interesting.
[0003] Building blocks are among the most popular educational toys for both parents and children. Their unique combination play allows children to create and assemble models, greatly increasing playability and long-term appeal. They also develop children's intelligence and improve hand-eye coordination.
[0004] Currently, the connection between adjacent toy pieces in toys is generally achieved by using a fixed plug-in structure or by using magnets to magnetically connect the two toy pieces. Fixed plug-in structures have noticeable unevenness at both ends of the connection. The protruding structure not only increases the risk of injury to the user, but also makes it easy to feel uncomfortable when playing with individual pieces. On the other hand, magnetically attached toys are difficult to connect firmly, and the connection is easily broken, resulting in an unstable structure after assembly. Summary of the Invention
[0005] The main objective of this invention is to provide a connection structure for toys that solves the problem of fixed protrusions at the connection positions.
[0006] This invention proposes a connecting structure for a toy, used to connect connecting blocks, including a protruding connecting structure and a recessed connecting structure;
[0007] The connecting block is provided with a protruding connecting structure and / or a recessed connecting structure;
[0008] The protruding connection structure includes a weak magnet, a slide rail, and a sliding block. The sliding block can slide along the slide rail, and a plug-in post is provided at the end of the sliding block away from the weak magnet.
[0009] The recessed connection structure includes a strong magnet and a insertion slot, with the strong magnet located at the bottom of the insertion slot;
[0010] The protruding connection structure is used to connect with its corresponding recessed connection structure so that two adjacent connection blocks can be connected together.
[0011] In the corresponding protruding and recessed connection structures, the magnetism of the strong magnet is greater than that of the weak magnet.
[0012] When the corresponding protruding connection structure and recessed connection structure are connected, the strong magnet attracts the sliding block, and the plug is inserted into the plug slot.
[0013] Furthermore, the sliding block includes a sliding locking part 322 and a plug-in post, wherein the cross-sectional area of the sliding locking part 322 is larger than the cross-sectional area of the plug-in post;
[0014] The slide includes a guide section and a concealed section. The cross-sectional area of the guide section is larger than that of the concealed section. The sliding locking section 322 is movably disposed in the guide section, and the plug-in post is movably disposed in the concealed section. The plug-in post is movably inserted into the concealed section.
[0015] Furthermore, the sliding block includes an inner connecting part, a sliding locking part 322 and a plug-in post in sequence, and the cross-sectional area of the sliding locking part 322 is larger than the cross-sectional area of the plug-in post and the cross-sectional area of the inner connecting part.
[0016] The slide includes a connecting guide section and a hidden section. The cross-sectional area of the guide section is larger than that of the hidden section. The inner connecting section and the sliding locking section 322 are movably disposed in the guide section. The plug-in post is movably disposed in the hidden section and is movably inserted into the hidden section.
[0017] Furthermore, the slide also includes an inner channel, which is located on the side of the guide section away from the hidden section, and the inner connecting section is movably inserted into the inner channel.
[0018] Furthermore, the cross-sectional area of the plug-in post is the same as the cross-sectional area of the inner connection part.
[0019] Furthermore, an assembly alignment structure is provided on two adjacent connecting blocks.
[0020] Furthermore, the weak magnet and the strong magnet are respectively one of the following: metal alloy magnet, ferrite permanent magnet and rubber magnet.
[0021] Furthermore, a guide slope is provided around the opening of the insertion slot.
[0022] Furthermore, when the corresponding protruding connecting structure's insertion slot and the recessed connecting structure's slide are opposite each other, the attraction of the strong magnet to the sliding block is greater than the sum of the attraction of the weak magnet to the sliding block, the weight of the sliding block, and the friction force between the sliding block and the slide.
[0023] Furthermore, the connecting block is equipped with a connecting magnet.
[0024] This invention proposes a connection structure for a toy, in which connecting blocks can be connected through corresponding protruding and recessed connecting structures. Specifically, the attraction of a strong magnet causes the sliding block to detach from the weak magnet and move along the slide track towards the strong magnet, allowing the insertion post to be inserted into the insertion slot. The strong magnet attracts the insertion post. Through the insertion of the insertion post and the insertion slot, the connection between the two connecting blocks can be made stable and better fixed in the set position. After the two connecting blocks separate, the sliding block retracts into the slide track under the attraction of the weak magnet, solving the problem of fixed protrusions at the connection position.

Detailed Implementation
[0030] The technical solution described in this paper will now be described in further detail with reference to the accompanying drawings.
[0031] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.
[0032] Reference Figure 1-4This invention proposes a connecting structure for a toy, used to connect connecting blocks 1, including a protruding connecting structure 3 and a recessed connecting structure 2; the connecting block 1 is provided with a protruding connecting structure 3 and / or a recessed connecting structure 2; the protruding connecting structure 3 includes a weak magnet 33, a slide rail 31 and a sliding block 32, the sliding block 32 can slide along the slide rail 31, and the end of the sliding block 32 facing away from the weak magnet 33 is provided with a plug post 321; the recessed connecting structure 2 includes a strong magnet 22 and a plug groove 21, the strong magnet 22 is located at the bottom of the plug groove 21; the protruding connecting structure 3 is used to connect with its corresponding recessed connecting structure 2, so that two adjacent connecting blocks 1 are connected together; in the corresponding protruding connecting structure 3 and recessed connecting structure 2, the magnetism of the strong magnet 22 is greater than that of the weak magnet 33; when the corresponding protruding connecting structure 3 and recessed connecting structure 2 are connected, the strong magnet 22 attracts the sliding block 32, and the plug post 321 is inserted into the plug groove 21.
[0033] Specifically, connecting block 1 is a separate block in the assembly toy. Connecting blocks 1 can be connected to each other through corresponding protruding connecting structures 3 and recessed connecting structures 2. Specifically, due to the attraction of the strong magnet 22, the sliding block 32 is detached from the weak magnet 33 and moves along the slide 31 towards the strong magnet 22, causing the insertion post 321 to be inserted into the insertion slot 21. The strong magnet 22 attracts the insertion post 321. Through the insertion of the insertion post 321 and the insertion slot 21, the connection between the two connecting blocks 1 can be made stable and better fixed in the set position. After the two connecting blocks 1 are separated, the sliding block 32 retracts into the slide 31 under the attraction of the weak magnet 33, avoiding unnecessary protrusion of the insertion post 321, which would affect the user's use and solve the problem of fixed protrusion at the connection position.
[0034] Specifically, in some embodiments, the sliding block 32 is made entirely of a material that can be attracted by a magnet; in some embodiments, the sliding block 32 is a structure made of a material that can be attracted by a magnet at both ends; in some embodiments, the sliding block 32 may include one or more plug-in posts 321.
[0035] Furthermore, in some embodiments, the sliding block 32 includes a sliding locking part 322 and a plug-in post 321, the cross-sectional area of the sliding locking part 322 being larger than the cross-sectional area of the plug-in post 321; the slide rail 31 includes a guide part 312 and a hidden part 311, the cross-sectional area of the guide part 312 being larger than the cross-sectional area of the hidden part 311, the sliding locking part 322 being movably disposed within the guide part 312, the plug-in post 321 being movably disposed within the hidden part 311, and the plug-in post 321 being movably inserted into the hidden part 311.
[0036] Specifically, the sliding block 32 can be limited by the cross-sectional area of the sliding locking part 322 being larger than that of the plug post 321, preventing the sliding block 32 from detaching from the connecting block 1 from the hidden part 311. Furthermore, the shape and size of the cross-section of the guide part 312 are matched with the shape and size of the cross-section of the guide part 312. The side wall of the guide part 312 also plays a limiting role, so that the sliding block 32 only slides along the guide part 312 and is not easy to swing. The connection structure of the toy works stably and smoothly.
[0037] Furthermore, referring to Figure 3 In some embodiments, the sliding block 32 includes an inner connecting portion 323, a sliding locking portion 322, and a plug-in post 321 in sequence. The cross-sectional area of the sliding locking portion 322 is larger than the cross-sectional area of the plug-in post 321 and the cross-sectional area of the inner connecting portion 323. The slide rail 31 includes a guide portion 312 and a hidden portion 311 that are connected. The cross-sectional area of the guide portion 312 is larger than the cross-sectional area of the hidden portion 311. The inner connecting portion 323 and the sliding locking portion 322 are movably disposed in the guide portion 312, and the plug-in post 321 is movably disposed in the hidden portion 311. The plug-in post 321 is movably inserted into the hidden portion 311.
[0038] Specifically, the sliding block 32 can be limited by the cross-sectional area of the sliding locking part 322 being larger than that of the plug post 321, preventing the sliding block 32 from detaching from the connecting block 1 from the hidden part 311. The shape and size of the cross-section of the guide part 312 are matched with the shape and size of the cross-section of the guide part 312. The side wall of the guide part 312 also restricts the guide part 312, so that the sliding block 32 only slides along the guide part 312 and is not easy to swing. The connection structure of the toy works stably and smoothly. The inner connecting part 323 is smaller than the sliding locking part 322, which can reduce the effective adsorption area of the weak magnet 33, making it easier for the sliding block 32 to move under the adsorption of the strong magnet 22.
[0039] Furthermore, in some embodiments, the slide 31 further includes an inner channel, which is located on the side of the guide portion 312 opposite to the hidden portion 311, and the inner connecting portion 323 is movably inserted into the inner channel.
[0040] Specifically, during the movement of the sliding block 32, the inner channel guides the inner connecting part 323.
[0041] Furthermore, in some embodiments, the cross-sectional area of the plug post 321 is the same as the cross-sectional area of the inner connection portion 323.
[0042] Specifically, the plug-in post 321 and the inner connecting part 323 have the same cross-sectional area. In some designs, the plug-in post 321 and the inner connecting part 323 can have the same length, so there is no need to distinguish them during assembly, making assembly more convenient.
[0043] Furthermore, in some embodiments, the weak magnet 33 and the strong magnet 22 are made of the same or different materials.
[0044] Specifically, the difference in magnetic force between the weak magnet 33 and the strong magnet 22 is achieved through the design of the shape or material of the magnet.
[0045] Furthermore, in some embodiments, the weak magnet 33 and the strong magnet 22 are respectively one of a metal alloy magnet, a ferrite permanent magnet, and a rubber magnet.
[0046] Specifically, the weak magnet 33 and the strong magnet 22 are designed according to the requirements, and the metal alloy magnets can be, but are not limited to, neodymium iron boron magnets, samarium cobalt magnets, and alnico magnets.
[0047] Furthermore, in some embodiments, a guide slope 211 is provided around the opening of the insertion slot 21.
[0048] Specifically, the insertion post 321 is guided into the insertion slot 21 by the guiding slope 211, making it easier for the insertion post 321 to be inserted into the insertion slot 21.
[0049] Furthermore, in some embodiments, when the insertion groove 21 of the corresponding protruding connecting structure 3 and the slide rail 31 of the recessed connecting structure 2 are opposite, the attraction force of the strong magnet 22 on the sliding block 32 is greater than the sum of the attraction force of the weak magnet 33 on the sliding block 32, the gravity of the sliding block 32, and the friction force between the sliding block 32 and the slide rail 31.
[0050] Specifically, the formula for calculating the attractive force of a magnet is:
[0051]
[0052] Where F represents the attractive force, B represents the magnetic induction intensity of the permanent magnet, A represents the effective adsorption area of the magnet, and μ0 represents the magnetic permeability of air (4π×10⁻⁶). -7 -N / A 2 ), μ r The relative permeability of the magnet is represented by d, and the distance between the permanent magnet and the object being attracted is represented by d. In some embodiments, the attraction force of the strong magnet 22 on the sliding block 32 is much greater than the attraction force of the weak magnet 33 on the sliding block 32, the gravity of the sliding block 32, and the friction force between the sliding block 32 and the slide rail 31, which can better achieve the goal of driving the sliding block 32 to insert into the slide rail 31.
[0053] Furthermore, the connecting block 1 is provided with a connecting magnet 4.
[0054] Specifically, in some embodiments, the connecting magnet 4 is located beside the protruding connecting structure 3 and the recessed connecting structure 2. The connecting magnet 4 serves as an alternative connecting structure. The magnetic attraction between the connecting magnets 4 of the two connecting blocks 1 can connect the two connecting blocks 1 without using the protruding connecting structure 3 and the recessed connecting structure 2. In some embodiments, since the connecting magnet 4 is used for direct connection and has a strong attraction force, the magnetic attraction between the connecting magnets 4 can be used to position the two connecting blocks 1. Then, by adjusting the angle of the connecting blocks 1, it is easier to align the insertion post 321 of the protruding connecting structure 3 and the insertion slot 21 of the recessed connecting structure 2, making it easier to assemble the connecting blocks 1. The magnet can serve as an assembly alignment structure.
[0055] Furthermore, in some embodiments, an assembly alignment structure is provided on two adjacent connecting blocks 1.
[0056] Specifically, the alignment structure is located on the side of the protruding connecting structure 3 and the recessed connecting structure 2. The alignment structure is used to guide the rapid assembly of two adjacent connecting blocks 1. In some embodiments, the alignment structure includes a protrusion and a groove. In some embodiments, in order to reduce the probability of causing injury to the user due to the protrusion being too sharp, the protrusion is set to be spherical or hemispherical, etc.
[0057] The present invention proposes a connection structure for a toy, in which connecting blocks 1 can be connected by corresponding protruding connecting structures 3 and recessed connecting structures 2. Specifically, the attraction of the strong magnet 22 causes the sliding block 32 to detach from the weak magnet 33 and move along the slide 31 toward the strong magnet 22, allowing the insertion post 321 to be inserted into the insertion slot 21. The strong magnet 22 attracts the insertion post 321. Through the insertion of the insertion post 321 and the insertion slot 21, the connection between the two connecting blocks 1 can be made stable and better fixed in the set position. After the two connecting blocks 1 are separated, the sliding block 32 retracts into the slide 31 under the attraction of the weak magnet 33, solving the problem of fixed protrusion at the connection position.
[0058] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
