Description

Technical Field

[0001] This utility model relates to the field of children's educational toys, specifically a rigid circuit-connected building block structure. Background Technology

[0002] Children's educational toys are toys specifically designed for children, aiming to consciously stimulate, exercise, and promote children's abilities in one or more developmental areas, such as cognition, physical development, emotional development, or social development, while providing entertainment and fun through play. There is a close correlation between rigid circuit-connected building block structures and children's educational toys, and they are widely applicable to the research and development and production of modular electrified building blocks.

[0003] Assembling the soft and hard boards of existing electrified building blocks is quite difficult. When the soft boards are glued, problems such as misalignment and glue overflow are prone to occur, while the hard boards rely on screws or glue for fixing, which leads to low assembly efficiency and affects the production and use of electrified building blocks. Utility Model Content

[0004] The purpose of this invention is to provide a rigid circuit board connected modular structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rigid board circuit connection type building block structure, including a building block body and building block holes. The top two sides of the building block body are fixedly connected to the building block body. A limiting platform is fixedly connected to the middle of the outer wall of the building block body, and a shallow groove is opened inside the limiting platform. The size of the shallow groove matches that of the flexible board. Elastic buckles are fixedly connected to the middle two sides of the inner wall of the building block body, and a convex-concave mating groove is set on the edge of the building block body to ensure that the positive and negative poles are forcibly aligned. Conductive contacts corresponding to the positive and negative poles of the flexible board or rigid board are reserved on the groove wall of the building block body.

[0006] The 3M flexible circuit board is precisely positioned and bonded by the limiting platform on the surface of the building blocks. At the same time, the snap-fit ​​structure enables quick tool-free installation of the rigid circuit board, thus making it compatible with both flexible and rigid circuit boards and improving production and assembly efficiency.

[0007] Preferably, a limiting sleeve is fitted onto the bottom of the outer wall of the limiting platform, and a paper tape is fixedly connected to one side of the outer wall of the limiting sleeve. An easy-tear opening is provided inside the paper tape, and a protective sleeve is fixedly connected to the side of the paper tape away from the limiting sleeve.

[0008] The diffusion of the adhesive layer is restricted by the cooperation of the limiting platform and the limiting sleeve.

[0009] Preferably, an extension strip is connected to one side of the outer wall of the protective sleeve, and the inner wall of the protective sleeve is fitted to the top of the outer wall of the limiting platform.

[0010] By pulling the extension strip, the protective sleeve is moved, causing it to detach from the limiting sleeve, thus revealing the shallow groove inside the limiting platform.

[0011] Preferably, both the limiting sleeve and the protective sleeve are square structures, and both the limiting sleeve and the paper tape are made of rubber.

[0012] The limiting platform is protected by a protective sleeve and a limiting sleeve to prevent external debris from entering the shallow groove inside the limiting platform.

[0013] Preferably, the inner wall of the building block body is provided with a base on both sides, and a slide rail is slidably connected to the middle of the bottom end of the base, and one side of the outer wall of the slide rail is fixedly connected to the inner wall of the building block body.

[0014] The base is guided by a slide rail to move it smoothly.

[0015] Preferably, the slide rail has an "L" shaped structure, the base is semi-circular, and limit pins are fixedly connected to both sides of the top of the base.

[0016] The movement of the base will cause the limit pin to move as well.

[0017] Preferably, the limiting pin is slidably connected to the block body, and the limiting pin has an inclined surface on the side away from the base, and the base and the limiting pin have a "U" shaped structure.

[0018] When the rigid plate moves down, the edge of its outer wall will exert a pushing force on the limiting pin, causing the limiting pin to drive the base to move away from the elastic buckle.

[0019] Preferably, a spring is fixedly connected to the top of the slide rail, and one side of the outer wall of the spring is fixedly connected to the middle of the top of the base. The base, the slide rail and the spring form an elastic telescopic mechanism.

[0020] The spring returns the base to its original position by generating elastic force. At this time, the limiting pin is located at the corner of the rigid plate, thereby restricting the corner of the rigid plate.

[0021] As can be seen from the above, the rigid circuit connection type modular structure provided by this utility model has the following beneficial effects.

[0022] By utilizing the limiting platforms on the surface of the building blocks, precise positioning and bonding of 3M flexible boards can be achieved. At the same time, a snap-fit ​​structure enables quick tool-free installation of rigid boards, thus making them compatible with both flexible and rigid circuit carriers and improving production and assembly efficiency.

[0023] The protective sleeve and the limiting sleeve protect the limiting platform, preventing external debris from entering the shallow groove inside the limiting platform, and the limiting platform and the limiting sleeve work together to limit the spread of the adhesive layer.

[0024] The rigid plate is secured by elastic buckles in the middle and by limiting pins at the edges and corners, thus stabilizing and preventing it from detaching from the main block. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-11This utility model provides a technical solution: a rigid circuit connection type building block structure, including a building block body 1 and building block holes 2. Building block bodies 1 are fixedly connected to both sides of the top of the building block body 1. A limiting platform 3 is fixedly connected to the middle of the outer wall of the building block body 1, and a shallow groove is formed inside the limiting platform 3, the size of which matches the flexible board. Elastic buckles 4 are fixedly connected to both sides of the middle of the inner wall of the building block body 1, and convex and concave mating grooves are provided on the edge of the building block body 1 to ensure forced alignment of the positive and negative electrodes. The wall has pre-drilled conductive contacts corresponding to the positive and negative poles of the flexible or rigid board; the bottom of the outer wall of the limiting platform 3 is fitted with a limiting sleeve 5, and a paper strip 6 is fixedly connected to one side of the outer wall of the limiting sleeve 5. The paper strip 6 has an easy-tear opening inside, and a protective sleeve 7 is fixedly connected to the side of the paper strip 6 away from the limiting sleeve 5; an extension strip 8 is connected to one side of the outer wall of the protective sleeve 7, and the inner wall of the protective sleeve 7 is in contact with the top of the outer wall of the limiting platform 3; both the limiting sleeve 5 and the protective sleeve 7 are square structures, and both the limiting sleeve 5 and the paper strip 6 are made of rubber.

[0029] In practice, the flexible circuit board is a 3M adhesive flexible circuit board, pre-covered with 3M acrylic foam adhesive and with release paper. The flexible circuit board integrates positive and negative contacts for the circuit, which can be connected by adhesive. The rigid circuit board is a snap-on rigid circuit board with anti-detachment notches on the edges to match the snap-on structure of the building blocks. The surface also has positive and negative contacts corresponding to the contacts of the flexible circuit board and the building blocks, and the circuit is connected by inserting the snap-on slots.

[0030] See Figures 1-6 At this time, both the limiting sleeve 5 and the protective sleeve 7 are fitted onto the outside of the limiting platform 3. The limiting sleeve 5 and the protective sleeve 7 protect the limiting platform 3 and prevent external debris from entering the shallow groove inside the limiting platform 3. When it is necessary to install the flexible board, first pull the extension strip 8 to move the protective sleeve 7, so that the protective sleeve 7 is separated from the limiting sleeve 5, thereby revealing the shallow groove inside the limiting platform 3. Then, peel off the release paper on the flexible board to expose the 3M adhesive surface. After that, align the flexible board with the shallow groove. At this time, the limiting platform 3 and the limiting sleeve 5 cooperate to restrict the spread of the adhesive layer. Then, use the initial tack of the 3M adhesive to lightly press and fix it, so that the adhesive surface is in full contact with the shallow groove. After that, depending on the specific needs, the protective sleeve 7 can be moved to cover the top of the limiting platform 3 to protect the flexible board, or the paper tape 6 can be torn off the protective sleeve 7 directly. After 24 hours of curing, the flexible board is flush with the surface of the limiting platform 3, and there is no glue overflow or lifting.

[0031] Thus, the protective sleeve 7 and the limiting sleeve 5 protect the limiting platform 3, preventing external debris from entering the shallow groove inside the limiting platform 3, and the limiting platform 3 and the limiting sleeve 5 cooperate with each other to limit the diffusion of the adhesive layer.

[0032] See Figure 5 , Figure 6 , Figures 8-11The building block body 1 has bases 9 on both sides of its inner wall, and a slide rail 11 is slidably connected to the middle of the bottom of the base 9. The outer side of the slide rail 11 is fixedly connected to the inner wall of the building block body 1. The slide rail 11 has an "L" shaped structure, the base 9 is semi-circular, and the top two sides of the base 9 are fixedly connected to limit pins 10. The limit pins 10 are slidably connected to the building block body 1, and the side of the limit pin 10 away from the base 9 has a beveled part. The base 9 and the limit pin 10 have a "U" shaped structure. The top of the slide rail 11 is fixedly connected to a spring 12, and the outer side of the spring 12 is fixedly connected to the middle of the top of the base 9. The base 9, the slide rail 11 and the spring 12 form an elastic telescopic mechanism.

[0033] In practice, first align the anti-detachment notch of the hard plate with the buckle slot inside the block, and insert it along the guide inside the slot. At this time, the elastic buckle 4 pops into the anti-detachment notch of the hard plate, achieving tool-free quick locking. Because the outer wall of the limiting pin 10 has a beveled part, when the hard plate moves down, the edge of its outer wall will push the limiting pin 10, causing the limiting pin 10 to drive the base 9 to move away from the elastic buckle 4. At this time, the base 9 will slide along the slide rail 11, and then guide the base 9 to move smoothly through the slide rail 11. At the same time, the movement of the base 9 will squeeze the spring 12, causing it to deform. As the rigid plate moves downward, the spring 12 will reset, and then generate elastic force to return the base 9 to its position. At this time, the limiting pin 10 is located at the corner of the rigid plate, thereby restricting the middle of the rigid plate through the elastic buckle 4 and the corner of the rigid plate by the limiting pin 10, thus stabilizing and limiting the rigid plate to prevent it from detaching from the block body 1. The entire installation process takes a short time. After installation, the rigid plate is flush with the surface of the block, and the contacts on the rigid plate are in pre-contact with the conductive contacts on the inner wall of the block.

[0034] During power-on assembly, building blocks with flexible or rigid boards are aligned and inserted using convex and concave slots. The slot structure forcibly guides the connection direction. During insertion, the convex and concave slots precisely align the positive and negative contacts of the flexible or rigid board with the corresponding contacts of the target building block, achieving reliable circuit conduction. After insertion, the bonding force at the joint is ≥5N. At this point, the flexible board is firmly held in place by the 3M adhesive and the constraint of the shallow slots, while the rigid board is stable and does not loosen due to the locking mechanism, thus ensuring a continuous and reliable circuit connection.

[0035] Furthermore, the limiting platform 3 on the surface of the building blocks is used to achieve precise positioning and bonding of 3M flexible boards. At the same time, a snap-fit ​​structure is adopted to achieve quick tool-free installation of rigid boards, thus making them compatible with both flexible and rigid circuit carriers and improving production and assembly efficiency.

[0036] The edges of the building blocks are equipped with convex and concave mating slots to ensure that the positive and negative poles are aligned, avoid reversed electrode connection, and improve the reliability of circuit connection. The soft board pasting and hard board snap-fit ​​installation processes do not interfere with each other. When building blocks are assembled through the building block hole 2, the flatness and good feel of the building blocks are the same as ordinary particles, while ensuring the stability of circuit connection.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
