Description

Technical Field

[0001] This utility model relates to the field of building block toys, and in particular to a light-emitting device for building block toys and a building block toy. Background Technology

[0002] Building blocks are toys that develop intelligence and improve hands-on skills. LEGO bricks are currently the most widely used building block toys, and their bricks are all of standard size. However, existing building block toys do not have light-up functions. In order to pursue some novel experiences, people have thought of adding light-up functions to building block toys. However, existing technologies include two approaches: one is to modify the structure of individual building blocks into light-emitting blocks, which is unsuitable for toys like Lego that use standard building block structures; and the other is to connect multiple light-emitting blocks using wires, which is inconvenient if the assembled toy is solid, as clamping the wires between adjacent blocks would affect the stability of the assembled structure. Another approach is to attach LEDs to the cavity walls if the assembled toy has internal cavities, but this method is also unsuitable for solid assembled toys. Therefore, a light-emitting device needs to be designed that neither alters the structural dimensions of existing standard building blocks nor affects the structural stability of the assembled toy. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a light-emitting device for building block toys and a building block toy.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a light-emitting device for building block toys, including a flexible circuit board with a width not greater than the width of the building block piece, the flexible circuit board including multiple mounting parts with lengths corresponding to the lengths of different building block pieces, which are spaced apart and / or not spaced apart, the mounting parts are provided with mounting through holes that can fit the protrusions of the building block pieces, and the flexible circuit board is also provided with at least one LED light and at least one electrical connection interface.

[0005] Preferably, the thickness of the flexible circuit board is no more than 0.3 mm.

[0006] Preferably, the flexible circuit board is also provided with creases for bending.

[0007] Preferably, the LED light is disposed on the mounting portion and / or on a first extension extending from the edge of the mounting portion.

[0008] Preferably, the electrical connection interface is disposed on a second extension extending from the edge of the mounting portion.

[0009] Preferably, the two mounting parts that are spaced apart are connected by a connecting part whose width is smaller than the width of the mounting part.

[0010] Preferably, the mounting part and the connecting part are integrally formed, or the mounting part and the connecting part are formed by splicing two flexible FPC plates through the form of particle protrusions and grooves, and both flexible FPC plates involved in the splicing have positive and negative electrode plates. When the two flexible FPC plates are spliced, the two sets of positive and negative electrode plates are pressed together to make the mounting part and the connecting part electrically connected.

[0011] Preferably, the mounting part is one or more of the following: strip-shaped, circular, or arc-shaped.

[0012] A building block toy includes multiple building block pieces that can be assembled into a certain shape, and a light-emitting device for the building block toy as described in any of the preceding claims that can be matched and installed in the assembly structure of the multiple building block pieces.

[0013] The beneficial effects of this utility model are as follows: This utility model adopts a flexible circuit board composed of multiple mounting parts. The mounting parts can be set according to their corresponding building block particles. The flexible circuit board is equipped with LED lights and mounting through holes. The flexible circuit board can be bent along with the assembly structure of the building block particles. The mounting through holes can easily fit the flexible circuit board onto the protrusions of the building block particles without affecting the assembly of the building block particles or the stability of the assembled structure.

Detailed Implementation

[0022] To more clearly illustrate the purpose, technical solution, and advantages of the embodiments of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description will be provided. Obviously, the described embodiments are some, but not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Examples of embodiments of this utility model Figures 1 to 7As shown, a light-emitting device for building block toys includes a flexible circuit board 1 with a width no greater than the width of a building block. The flexible circuit board 1 is an FPC board, and its width is related to the width of the building block to be mounted. For example, if the flexible circuit board is to be mounted on a 1x4 LEGO brick, since a basic LEGO unit is a 1x1 brick with dimensions of 8*8*9.6mm, the length, width, and height of the brick correspond to 8mm, 8mm, and 9.6mm respectively. For a 1x4 brick, its length, width, and height correspond to 32mm, 8mm, and 9.6mm respectively. At this point, the width of the flexible circuit board 1 must be less than 8mm. This ensures that the flexible circuit board 1 will not be exposed on the assembled building block toy when it is installed on the building block pieces, thus not affecting the appearance of the assembled building block toy. The flexible circuit board 1 includes multiple mounting parts 2 with spaced intervals and / or no spaced intervals, each corresponding to the length of a different building block piece. That is, one mounting part 2 corresponds to one building block piece. The adjacent mounting parts 2 are spaced apart or placed close together depending on the position where the lights need to be lit on the building block toy to be assembled. For example, if the position where the lights need to be lit is on the same layer and perpendicularly spliced ​​together... On a 1x8 brick and a 1x3 brick, the length of one mounting part 2 is equivalent to the length of the 1x8 brick, and the length of the other mounting part 2 is equivalent to the length of the 1x3 brick. The two mounting parts 2 are placed close together and perpendicular to each other, with no gap between them. If the two bricks are placed close together on the same layer and in the same row, then the mounting part 2 can be set as one, with its length being equivalent to the sum of the lengths of the two bricks. If the position where the light needs to be lit is the 1x8 brick on the lower layer and the 1x3 brick on the upper layer, then one mounting part 2... The length of part 2 is still equivalent to the length of a 1x8 brick, and the length of the other mounting part 2 is still equivalent to the length of a 1x3 brick. However, the two mounting parts 2 are set alternately. After the lower mounting part 2 is installed on the lower building block, the flexible circuit board 1 is bent upward to the upper building block, and then bent again to install the upper mounting part 2 on the upper building block. Since the standard building block is strip-shaped, round or arc-shaped, the mounting part 2 is selected according to the shape of the building block to be installed, choosing one or more of the following: strip (long strip or square), round or arc-shaped.To facilitate bending of the flexible circuit board 1, creases 10 are provided on the flexible circuit board 1 for bending. Creases 10 also serve as a reminder that bending of the flexible circuit board 1 is required during installation, preventing installation errors. When two adjacent mounting portions 2 are spaced apart, a connecting portion 5 with a width smaller than the width of the mounting portion 2 is between them. This means the connecting portion 5 is also part of the flexible circuit board, maintaining unobstructed electrical connections for the light-emitting devices. In this case, if two adjacent mounting portions 2 are spaced apart and side-by-side on the same layer, the connecting portion 5 is elongated. If two adjacent mounting portions 2 are spaced apart on the same layer at a certain angle and not parallel, the connecting portion 5 is elongated. At this point, a bend angle with the same included angle is set at the corresponding position of the connecting part 5. The two ends of the bend angle are in the same direction as the corresponding mounting part 2. If two adjacent mounting parts 2 are set parallel to each other on the same layer, the connecting part 5 is set as a strip structure perpendicular to the two mounting parts 2. The connecting part 5 can pass through the position between the outer wall of the protrusion of the building block and the edge of the top surface of the building block or through the gap between two adjacent protrusions on the building block. When there is a cavity in the assembled building block toy, the connecting part 5 can also be set in the cavity. If multiple mounting parts 2 are set alternately on building blocks on different layers, and there is a cavity inside the assembled building block toy, the connecting part 5 can be located in the cavity. The assembled building block toy is solid. The connecting part 5 can extend sequentially from bottom to top from the gap between two adjacent building blocks on the same layer, thus maintaining the integrity of the flexible circuit board 1 and facilitating its installation. The protrusions on the building blocks are small cylindrical protrusions on top of the building blocks. The mounting part 2 is provided with mounting through holes 20 that can fit over the protrusions of the building blocks. That is, the mounting part 2 is provided with mounting through holes 20, and the mounting part 2 fits over the protrusions of the building blocks using the mounting through holes 20. The diameter of the mounting through holes 20 is slightly larger than the outer diameter of the protrusions of the building blocks. The number of mounting through holes 20 on the mounting part 2 is the same as the number of protrusions on the building blocks to be installed. The building blocks are 1x5 bricks, meaning each block has five raised dots arranged in a row on top. The mounting part 2 is correspondingly equipped with five mounting through holes 20 arranged in a row. The flexible circuit board 1 also has at least one LED light 3 and at least one electrical connection interface 4. The LED light 3 is mounted on the mounting part 2 corresponding to the building block that needs to light up. The LED light 3 can be the same or different LEDs depending on the requirements. The electrical connection interface 4 is located on the flexible circuit board 1 and is used to connect to an external power source or other light-emitting devices. One or more electrical connection interfaces 4 can be provided for convenient use according to the application requirements.

[0024] Further improvements include ensuring that the thickness of the flexible circuit board 1 is no greater than 0.3mm, preferably less than 0.2mm, so as not to affect the assembly between the building blocks and the stability of the assembled structure.

[0025] Further improvements, such as Figures 1 to 3 As shown, the LED light 3 is disposed on the mounting part 2 and / or on the first extension 21 extending from the edge of the mounting part 2. The first extension 21 is located on the side of the mounting part 2 facing the inside of the building block toy after the mounting part 2 is mounted on the building block pieces. That is, one way is to place the LED light 3 on the edge of the mounting part 2, another way is to place it between two adjacent mounting through holes 20 on the mounting part 2, and a third way is to extend the first extension 21 from the edge of the mounting part 2 and then place the LED light 3 on the first extension 21. One or more of the three methods can be selected as appropriate.

[0026] Further improvements, such as Figures 1 to 7 As shown, the electrical connection interface 4 is provided on the second extension 22 extending from the edge of the mounting part 2. The second extension 22 extends from the mounting part 2. After the mounting part 2 is installed on the building block, the second extension 22 can be exposed to facilitate connection with an external power supply or with other light-emitting devices.

[0027] Figures 1-3 The image shows a configuration where the mounting part 2 and the connecting part 5 are integrally formed.

[0028] The following describes the installation part and the connecting part, which are formed by splicing two flexible FPC boards 13 with granular protrusions and grooves. It should be noted that the granular protrusions and grooves can be implemented by setting granular protrusions and grooves on two flexible FPC boards 15 respectively, or by setting through holes on both flexible FPC boards 15, and completing the detachable pressing connection by the pressing force of two external building blocks.

[0029] like Figures 4-7 As shown, both flexible FPC boards 13 involved in the splicing have positive electrode plates 11 and negative electrode plates 12. Simultaneously, the two sets of positive electrode plates 11 and negative electrode plates 12 are pressed together to conduct electricity, thus electrically connecting the mounting part 2 and the connecting part 5. Connections between different blocks are made and energized through the pressing of the flexible FPC boards 13, making operation more convenient and reducing operational difficulty. The number of sets of particle bumps and grooves involved in the splicing can be one set, or... Figures 4-7 The number of groups shown can be two or more, and there is no limitation on this.

[0030] It should be noted that the flexible FPC board 13 involved in splicing can have a set of positive electrode 11 and negative electrode 12 on one side, or it can have a set of positive electrode 11 and negative electrode 12 on both sides. The double-sided setting is more reasonable and more applicable. Both of these setting methods are within the scope of protection of this application.

[0031] To increase the area of ​​the positive electrode 11 and the negative electrode 12, clearance grooves can be provided on the positive electrode 11 and the negative electrode 12 to avoid the particle protrusions or grooves on the flexible FPC board 13, i.e. Figures 4-7 The arrangement shown is such that the positive electrode 11 and the negative electrode 12 are arranged around the particle protrusions or grooves;

[0032] A building block toy includes multiple building blocks that can be assembled into a certain shape, and a light-emitting device for the building block toy as described above, which can be matched and installed in the assembly structure of the multiple building blocks. The building blocks are selected from existing standard building blocks, such as Lego building blocks, which can be assembled into a certain shape, such as a car, a doll, etc. According to the number of light-emitting positions and the specifications of the building blocks of the required light-emitting positions, a corresponding number of mounting parts 2 that match the specifications of the corresponding building blocks are set. The mounting parts 2 are connected by connecting parts 5, and the length of the connecting parts 5 can be set according to the distance between two mounting parts 2. During the assembly process, the corresponding mounting parts 2 are installed on the corresponding building blocks that need to be lit by bending the flexible circuit board 1 at the crease 10 position.

[0033] In summary, the new integrated solution of this application has at least the following advantages compared with the old component-based solution:

[0034] 1. All components (LED beads, resistors, capacitors, main control IC, etc.) are integrated on several large FPC boards, greatly reducing the number of accessories in a set of lighting fixtures;

[0035] 2. FPC boards replace most of the wires, reducing the tangled and redundant wires and making them less prone to breakage;

[0036] 3. The circuit is less prone to short circuits, making it safer;

[0037] 4. The large quantity and limited number of small parts reduce the loss rate and lower the risk of accidental ingestion;

[0038] 5. From a product manufacturing perspective, the new solution can be processed using specialized surface mount equipment, making the production line safer and increasing efficiency by at least 50% compared to the previous solution. It also enables batch and mechanized gluing operations, resulting in stronger component adhesion.

[0039] Although the present invention has been described in detail above with general description and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
