Description

Technical Field

[0001] This invention relates to the field of research and development technology of assembly modules for granular intelligent building block toys, and in particular to a power data cable plug, main controller, and splitter for granular building block toys.

[0002] The main controller refers to a battery-powered control module used in granular building block toys. Background Technology

[0003] The assembly module of the aforementioned granular building block toy refers to any independent assembly piece within the toy. Among the various assembly modules of the granular building block toy, "boards" or "bricks" are the two most basic building block modules; both "boards" and "bricks" have a square shell structure, with "cylindrical studs" on the top of the square shell, such as... Figure 1 The cylindrical protrusions indicated by reference numeral A in the attached diagram; the opening of the square shell cavity is provided with an "insertion port for the cylindrical protrusions", as shown in the figure. Figure 3 The dotted lines in the attached diagram (B1, B2) indicate the following: the number of cylindrical studs on the top of the "board" and "brick" corresponds to the number of cylindrical stud insertion holes at the opening of the square shell cavity, and their nominal diameters are equal, both being 4.8 mm. A slight interference fit is used between the cylindrical studs and their insertion holes. Utilizing the "hole-and-column connection principle," the cylindrical studs of one building block module are pressed into the insertion holes of another building block module, allowing the two building blocks to be securely joined together. Through this joining method, various building blocks can be assembled into various toy shapes. Based on the "hole-and-column connection principle," the granular building blocks also incorporate a pin-and-pin hole and cross-axis-and-cross-axis hole joining structure. In this invention, the cylindrical studs, cylindrical stud insertion holes, pin holes, and cross-axis holes provided on the building block are collectively referred to as the joining structure on the building block.

[0004] In the assembly module of the granular building block toy, the top of each "cylindrical stud" corresponding to the square shell is a square with a side length of 8 mm; a "board" or "brick" with only one "cylindrical stud" is called a "unit" "board" or "brick". The height of the "board" is 8 mm × 0.4 = 3.2 mm, the height of the "brick" is 8 mm × 1.2 = 9.6 mm, and the diameter of the cylindrical stud is 8 mm × 0.6 = 4.8 mm. People are accustomed to determining the name of the assembly module according to the number of cylindrical studs on the assembly module. For example, a 3-unit board means that a 24 mm × 8 mm × 3.2 mm square shell has 3 cylindrical studs on the top; a 2 × 2-unit brick means that a 16 mm × 16 mm × 9.6 mm square shell has 4 cylindrical studs arranged in 2 rows and 2 columns on the top.

[0005] In existing granular building block toys, the power data lines for various sensors and micro-motors are connected to the main controller using a PF-type connector, such as... Figure 14 As shown, the PF-type plug is based on a 2×2 unit splicing module. The upper part is the slot end of the PF-type plug, including four cylindrical protrusions. Two of these protrusions remain unchanged, while the other two are combined into a wiring slot with four electrical contacts. The outer wall of the wiring slot retains the splicing function of the two cylindrical protrusions. Below this is the plug end of the PF-type plug, including four cylindrical protrusion insertion openings. Two of these openings remain unchanged, and the inner walls of the other two openings retain the splicing function of the two cylindrical protrusion insertion openings. A wiring plug with four electrical contacts is located in the middle. (See diagram below.) Figure 15 The image shows the state of the PF type plug's slot end, the four electrical contacts on the plug end, and the 4-pin ribbon cable before the pressing process. The PF type plug's slot end has a 4-pin ribbon cable positioning groove to ensure that each wire core of the 4-pin ribbon cable is aligned with the pins of the electrical contacts. Then, the plug end of the PF type plug is pressed into the slot end of the PF type plug, causing the pins of the four electrical contacts to pierce the insulation of the 4-pin ribbon cable and connect to the wire cores. Because the pins of the electrical contacts are made of copper, which has relatively weak rigidity, it is common for the pins to fail to pierce the insulation and bend, or for the pins to be misaligned and connect two wire cores simultaneously, resulting in defective products. The PF type plug is connected to an actuator via the 4-pin ribbon cable; the actuator includes a micro motor and various sensors. Figure 16 , Figure 17 The diagram shows the structure and control system principle of the PF-type plug-slot terminal main controller used in existing technologies for granular building block toys. The PF-type plug-slot terminal main controller includes a main board and a housing. The main board includes a main control IC and a PF-type plug-slot terminal. The main control IC is connected to the electrical contacts of the PF-type plug-slot terminal. The PF-type plug-slot terminal is located on top of the housing of the PF-type plug-slot terminal main controller (the structure within the dashed box). After the plug end of the micro motor or sensor PF-type plug is connected to it, it can obtain power from the output terminal main controller of the PF-type plug, and execute the control commands sent by the PF-type plug-slot terminal main controller, or send signals to the PF-type plug-slot terminal main controller. The slot end on one PF-type plug can also be plugged into the plug end of another PF-type plug.

[0006] While the PF-type plug is convenient and quick to use, it inevitably has three drawbacks due to its specific structure: first, the manufacturing process has defects that lead to a high defect rate; second, the wiring terminals at the slot end are exposed, which poses a risk of short circuits during operation; and third, the power and data cables occupy one end of the housing, hindering its flexibility in assembling modular shapes.

[0007] Despite these defects of the PF type plug, due to the established habit of using the PF type plug, power data cable plugs in the field of granular building block toy technology can only adopt the PF type plug structure design. Therefore, no one has questioned or proposed an effective improvement plan for the aforementioned technical defects of the PF type plug. Summary of the Invention

[0008] To address the technical problems existing in the PF-type plug of the power data cable for granular building block toys, this invention proposes a technical solution for a power data cable plug, main controller, and splitter for granular building block toys as follows:

[0009] A power data cable plug for a granular building block toy, the power data cable plug for the granular building block toy includes an upper cover box, a bottom cover plate, and a circuit board;

[0010] The top cover box is a 2×2 unit granular building block assembly module with a height of 6.4 mm. It includes a top plate, a bottom opening, a front side plate, a rear side plate, a left side plate, and a right side plate. The outer surface of the top plate has four cylindrical protrusions, and the inner surface of the top plate has a circuit board, a Type-C male connector, and a power data cable limiting groove. The front and rear side plates each have two slots, and the left side plate has a power data cable retaining plate opening. The height of the power data cable retaining plate opening extends through the height of the left side plate, and the part where it intersects with the top plate is cut off.

[0011] The bottom cover plate includes a type-c male connector mounting hole, an inner stiffening plate, an outer stiffening plate, a front side wall, a rear side wall, and a power data cable clip plate. The outer sides of the front side wall and the rear side wall are each provided with two clips.

[0012] The circuit board includes a circuit board input terminal, a type-C male connector, a circuit board output terminal, and a power data line; the type-C male connector is fixedly electrically connected to the circuit board input terminal by a soldering process, and one end of the power data line is fixedly electrically connected to the circuit board output terminal by a soldering process.

[0013] The Type-C male connector is inserted into the Type-C male connector mounting hole of the bottom cover plate. The circuit board is embedded in the positioning groove. The power data cable is placed along the inner rib of the bottom cover plate to the power data cable holder. The upper cover box is fastened to the bottom cover plate, so that the power data cable holder enters the power data cable holder opening. Since the height of the power data cable holder is less than the height of the power data cable holder opening, a power data cable receiving groove is formed at the upper end of the power data cable holder opening. The claws on the front and rear side walls of the bottom cover plate are correspondingly engaged in the slots of the front and rear side plates of the upper cover box. The bottom cover plate, its outer rib plate, and auxiliary protrusions form two parts with the inner wall of the upper cover box: the first part is two cylindrical protrusion embedding openings, and the second part is the Type-C male connector installed in the middle of the two cylindrical protrusion embedding openings, forming a double cylindrical protrusion embedding opening around the Type-C male connector.

[0014] A main controller includes a motherboard and a housing. The motherboard includes a main control IC and a Type-C female power data cable connector. The main control IC is connected to the Type-C female power data cable connector, which is located on the housing of the main controller. The Type-C female power data cable connector of the main controller is compatible with the Type-C male power data cable connector of the granular building block toy and can be plugged into the Type-C male power data cable connector of the granular building block toy.

[0015] A power splitter includes a Type-C female power data input port, a Type-C female power data output port one, and a Type-C female power data output port two. All three ports are compatible with the Type-C male power data cable connector for granular building block toys and can be plugged into them.

[0016] The method of using the power data cable plug, main controller, and splitter for a granular building block toy described in this invention is as follows: Take the power data cable plug for the granular building block toy and electrically connect the lead end of its power data cable to the interface of an actuator such as an infrared sensor, camera, or micro motor in the granular building block toy. It can then be connected to a main controller equipped with a Type-C female connector for the power data cable connection port. Its ease of use is no less than that of a PF type plug, and due to the connection characteristics of the Type-C interface, its connection safety and reliability are superior to those of a PF type plug.

[0017] The beneficial effects of the power data cable plug, main controller, and splitter for granular building block toys described in this invention are as follows: the Type-C male connector of the power data cable plug for granular building block toys is connected via a soldering process through the power data cable of the circuit board, effectively overcoming the high defect rate of PF type plugs; in the working state, the Type-C male connector of the power data cable plug for granular building block toys is inserted into the Type-C male and female connectors of the main controller, and the wiring terminals are enclosed in the housing, eliminating the potential for short circuits; and because a power data cable receiving groove is formed at the upper end of the power data cable retainer, the power data cable can be placed in the power data cable receiving groove without hindering the splicing with other building block modules.

[0018] Based on the above core technical solutions, and according to the actual situation, further improvements and limitations can be made to some technical features of the power data cable plug and main controller of the granular building block toy, which can also yield a variety of optimized technical solutions.

[0053] The technical solution of the power data cable plug, main controller, and splitter for a granular building block toy according to the present invention will be further described below with reference to specific embodiments:

[0054] Example 1:

[0055] like Figures 1 to 5 As shown, a power data cable plug for a granular building block toy includes an upper cover box 1, a bottom cover plate 2, and a circuit board 3.

[0056] The top cover box 1 is a 2×2 unit granular building block assembly module with a height of 6.4 mm. It includes a top plate 11, a bottom opening 12, a front side plate 13, a rear side plate 14, a right side plate 15, and a left side plate 16. The top plate 11 has four cylindrical protrusions on its outer surface and a limiting groove (not shown) for a circuit board 3 and a power data cable 34 on its inner surface. The front side plate 13 and the rear side plate 14 each have two slots. The left side plate 16 has a power data cable retaining plate opening 161. The height of the power data cable retaining plate opening 161 extends through the height of the left side plate 16, and the part where it intersects with the top plate 11 is cut off.

[0057] The bottom cover plate 2 includes a type-c male connector mounting hole 21, a positioning groove 22, an inner rib plate 23, a power data cable clip plate 24, an outer rib plate 25, a front side wall 26, and a rear side wall 27. The front side wall 26 and the rear side wall 27 are each provided with two claws on their outer sides.

[0058] The circuit board 3 includes a first end 31 of the circuit board, a type-c male connector 32, a second end 33 of the circuit board, and a power data line 34; the type-c male connector 32 is fixedly electrically connected to the first end 31 of the circuit board by a brazing process, and one end of the power data line 34 is fixedly electrically connected to the second end of the circuit board by a brazing process.

[0059] The Type-C male connector 32 is inserted into the Type-C male connector mounting hole 21 of the bottom cover plate 2. The circuit board 3 is embedded in the positioning groove 22. The power data cable 34 is placed along the inner rib plate 23 of the bottom cover plate 2 to the power data cable holder 24. The upper cover box 1 is fastened to the bottom cover plate 2, so that the power data cable holder 24 enters the power data cable holder opening 161. Since the height of the power data cable holder 24 is less than the height of the power data cable holder opening 161, the... The upper end of the power data cable slot 161 forms a power data cable receiving groove, the function of which is to allow the power data cable 34 to be inserted into the receiving groove, so that it can be seamlessly spliced ​​with the adjacent splicing module; the claws on the front side wall 26 and rear side wall 27 of the bottom cover plate 2 are correspondingly engaged into the slots of the front side plate 13 and rear side plate 14 of the upper cover box 1; the bottom cover plate 2, its outer rib plate 25 and auxiliary protrusions 28 and the inner wall of the upper cover box 1 form two parts: the first part is two cylindrical protrusion embedding openings, such as Figure 3 The dotted line indicates the location of B1; the second part is the type-C male connector 32 installed between the two cylindrical protrusion insertion ports, forming a double cylindrical protrusion insertion port around the type-C male connector 32, as shown. Figure 3 At the position indicated by the dotted line in B2, the width of the double cylindrical protrusion insertion port is 4.8 mm, the length is 12.8 mm, and the height is 2.1 mm.

[0060] Example 2:

[0061] like Figure 6 , Figure 7 As shown, a main controller includes a motherboard 6 and a housing. The motherboard 6 includes a main control IC and a Type-C female power data cable connector. The main control IC is connected to the Type-C female power data cable connector, which is located on the housing of the main controller. The Type-C female power data cable connector of the main controller is compatible with the Type-C male power data cable connector for the granular building block toy described in Embodiment 1, and can be plugged into the Type-C male power data cable connector for the granular building block toy.

[0062] like Figure 6 As shown, the dashed box contains the main controller's power data cable connector Type-C female connector, which is compatible with the Type-C male connector of the granular building block toy power data cable plug described in Embodiment 1. It includes four cylindrical protrusions, two of which remain unchanged. The main controller's power data cable connector Type-C female connector is located between the other two cylindrical protrusions. The outer contours of the two cylindrical protrusions form double cylindrical protrusions. When the Type-C male connector of the granular building block toy power data cable plug described in Embodiment 1 is inserted into the Type-C female connector, the double cylindrical protrusion insertion port surrounding the Type-C male connector 32 also simultaneously engages with the double cylindrical protrusions. Furthermore, the two cylindrical protrusion insertion ports of the first part simultaneously engage with the two cylindrical protrusions adjacent to the Type-C female connector.

[0063] like Figure 11 The diagram shows the usage status of the power data cable plug for the granular building block toy described in Embodiment 1 and the main controller described in this embodiment. The Type-C female connector of the main controller's power data cable is connected to the actuator via the power data cable plug for the granular building block toy described in Embodiment 1. The intelligent control system of a granular building block toy typically includes one main controller configured with several actuators. The actuators refer to various sensors with a building block assembly structure on their housing, including ultrasonic sensors, knob sensors, motion sensors, digital tubes, sound sensors, temperature / humidity sensors, light sensors, reading pen modules, touch sensors, push switches, RGB lights, illumination lights, dot matrix screens (8x16), and other signal acquisition actuators, as well as power output actuators such as metal servos, plastic servos, and micro motors. Each actuator is equipped with a power data cable plug for the granular building block toy, which is interconnected with the main controller.

[0064] Example 3:

[0065] Compared with Embodiment 2, the difference in this embodiment is that the power data cable connector of the main controller includes a 24-pin Type-C female connector, a 16-pin Type-C female connector, a 12-pin Type-C female connector, and a 6-pin Type-C female connector. Correspondingly, the Type-C male connector of the power data cable plug of the granular building block toy described in Embodiment 1 must be compatible with it.

[0066] According to the functional settings of the main controller, the number of pins on the Type-C female power data cable connector of the main controller can be selected as 24Pin, 16Pin, 12Pin or 6Pin. Taking advantage of the multiple pins of the Type-C interface, a multi-pin Type-C female connector on the main controller can be transformed into a power data cable connector with different functions through a splitter, which facilitates the expansion and connection of various actuators and brings great convenience to the main controller to flexibly perform its functions.

[0067] Example 4:

[0068] like Figure 8 , Figure 9 , Figure 10 As shown, compared with Embodiment 2 or Embodiment 3, the difference in this embodiment is that: a manual control switch is also included between the power data line connector (Type-C female) of the main controller and the main controller IC of the main controller.

[0069] Example 5:

[0070] Compared with Embodiment 4, the difference in this embodiment is that: the main controller includes a first power data line connector Type-C female 65, a second power data line connector Type-C female 66, a third power data line connector Type-C female 67, and a fourth power data line connector Type-C female 68, and a manual control switch is provided between each of the power data line connector Type-C female 65 and the main control IC of the main controller.

[0071] Example 6:

[0072] like Figure 12As shown, a splitter 8 includes a Type-C female power data input port 81, a Type-C female power data output port 82, and a Type-C female power data output port 83. The Type-C female power data input port 81, the Type-C female power data output port 82, and the Type-C female power data output port 83 of the splitter 8 are all compatible with the Type-C male power data cable connector for the granular building block toy, and can be plugged into the Type-C male power data cable connector for the granular building block toy described in Embodiment 1.

[0073] like Figure 13 The diagram shows the usage status of the power data cable plug for the granular building block toy described in Embodiment 1, the main controller described in Embodiment 2, and the splitter described in this embodiment. When the main controller has one Type-C female power data cable connector that needs to be connected to two actuators, firstly, use a connecting cable with two power data cable plugs for the granular building block toy to connect the Type-C female power data input port 81 of the splitter described in this embodiment to the main controller described in Embodiment 2. Then, connect the power data cable plugs for the granular building block toy of the two selected actuators to the Type-C female power data output port 82 and the Type-C female power data output port 83 of the splitter described in this embodiment. It should be noted that the main controller has two Type-C female power data cable connectors specifically for connecting micro motors, and the splitter described in this embodiment cannot use these two Type-C female power data cable connectors.

[0074] The beneficial effects of the power data cable plug, main controller, and splitter for granular building block toys described in this invention are as follows: It overcomes the defects of existing technologies, creating a new power data cable plug and main controller for granular building block toys. The Type-C interface and multi-core ribbon cable are connected using a soldering process, effectively overcoming the high defect rate of PF-type plugs. Because the Type-C interface allows the wiring endpoints to be enclosed within the housing, and the power data cable plug housing has a power data cable receiving slot, the wiring endpoints are enclosed within the housing during operation, eliminating the risk of short circuits. The power data cable can be placed in the power data cable receiving slot, facilitating its participation in the assembly of building blocks.

[0075] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solutions and embodiments of the present invention, should be covered within the scope of protection of the present invention.
