[0002] Building blocks are a series of modular components with standardized shapes or connection methods, designed for free assembly and creative construction through stacking, splicing, and combination. The modular motor assembly of building blocks is a core component specifically designed to add motion and control functions to static building block structures. The building block motor serves as the power unit for the building block model, providing drive functionality for the toy.

[0003] Existing block motors cannot accurately match the standard layout of blocks, making it difficult to directly embed them into the block structure. They usually require additional adapters to connect with the blocks, resulting in poor size adaptability of the block motors. Furthermore, the block motors do not have a cable winding mechanism, and excessively long, loose cables can easily get caught in rotating gears, tracks, or other moving parts, causing the model to jam.

[0010] The power cable is guided by moving it into the movable hole.

[0011] Preferably, the first rubber sleeve and the second rubber sleeve are combined in an elliptical shape to wrap the cable and prevent damage or breakage of the power cable during the clamping process.

[0012] The power supply cable is wrapped with rubber sleeves No. 1 and No. 2 to improve its tensile strength.

[0030] 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.

[0031] Please see Figures 1-6This utility model provides a technical solution: a modular power motor assembly for building blocks, including a first mounting shell 1, a second mounting shell 2, a micro DC motor 3, and a winding mechanism 13. The bottom of the outer wall of the first mounting shell 1 is connected to the second mounting shell 2, and the micro DC motor 3 is installed in the middle of the inner wall of the second mounting shell 2. The output end of the micro DC motor 3 is connected to a reduction gear set 4, and the output end of the reduction gear set 4 is connected to an output shaft 5. A control circuit board 6 is connected to the middle of the outer wall of the micro DC motor 3 through wires, and power supply cables 7 are connected to both sides of the outer wall of the control circuit board 6. A power plug 8 is connected to the side away from the control circuit board 6. The top of the outer wall of the first mounting housing 1 is fixedly connected with a connecting particle hole 9 that matches the building block. Both the first mounting housing 1 and the second mounting housing 2 have output connection holes in the middle of their outer walls, which can be connected to axles or other external actuators. The bottom and sides of the outer walls of the first mounting housing 1 and the second mounting housing 2 have mounting holes, and corresponding splicing protrusions or recesses on the outside, which can be spliced ​​with other building block modules. The control circuit board 6 is electrically connected to the micro DC motor 3 to realize the control of the motor drive, and can support wireless communication modules or other control interfaces.

[0032] For specific implementation, please refer to Figures 3-6 First, place the miniature DC motor 3, the reduction gear set 4, and the control circuit board 6 into the second mounting housing 2 in sequence. Then, connect the output shaft 5 to the output end of the reduction gear set 4. Next, connect and fix the first mounting housing 1 to the second mounting housing 2, so that all components are compactly arranged in the housing compatible with the building blocks. Then, pull the power cable 7 to connect the power plug 8 to the socket, thereby providing power to the building block motor.

[0033] Next, the shell can be easily combined with other building blocks through the particle holes 9 without the need for additional fixing structures. The built-in control circuit board 6 makes the motor drive more reliable and precise, and the functions can be switched through wireless communication or buttons. The built-in Teflon power cable provides a standardized power supply interface, which is convenient for connecting to power modules or other components. Compared with traditional motor modules, the size is significantly reduced, the external wiring is simplified, and efficient control and stable power supply of the motor are achieved. It can also be directly assembled with building blocks, thereby significantly improving the dynamic function and playability of building block toys.

[0034] See Figure 3 and Figure 8 Both mounting housing 1 and mounting housing 2 have movable holes 10 at the rear of their outer walls. A rubber sleeve 11 is fixedly connected inside the movable hole 10 at the rear of mounting housing 1, and a rubber sleeve 12 is fixedly connected inside the movable hole 10 at the rear of mounting housing 2. The rubber sleeves 11 and 12 are combined to form an ellipse, which wraps around the cable to prevent the power cable 7 from being damaged or broken during the connection process.

[0035] In practice, when the first mounting housing 1 is connected to the second mounting housing 2, the power supply cable 7 is moved in advance so that it is located inside the movable hole 10 to avoid damage or breakage of the power supply cable 7 during the connection process between the first mounting housing 1 and the second mounting housing 2. Afterwards, the power supply cable 7 is wrapped with the first rubber sleeve 11 and the second rubber sleeve 12 to improve the tensile strength of the power supply cable 7.

[0036] See Figure 2 , Figure 6 and Figure 7 The winding mechanism 13 includes a winding rod 1301 connected to the inner wall of the second mounting housing 2. A locking groove 1302 is provided on one side of the outer wall of the winding rod 1301, and a limiting pin 1305 is movably connected to the other side of the inside of the winding rod 1301. The outer wall of the limiting pin 1305 is fixedly connected to the inner wall of the first mounting housing 1. The limiting pin 1305 and the winding rod 1301 are rotatably connected. A fixing member 1303 is connected inside the locking groove 1302. Both the fixing member 1303 and the locking groove 1302 are "+" shaped structures. A knob 1304 is welded to one side of the outer wall of the fixing member 1303.

[0037] In practice, since the fixing part 1303 is connected to the knob 1304, the knob 1304 is moved first so that the fixing part 1303 is inserted into the snap-fit ​​groove 1302. At this time, the fixing part 1303 and the winding rod 1301 are engaged. Then, when the knob 1304 is turned, the winding rod 1301 will rotate around the limit pin 1305 as the axis. At this time, the limit pin 1305 guides the winding rod 1301 to rotate smoothly. Then, the power supply cable 7 is wound up by the rotation of the winding rod 1301.

[0038] The power supply cable 7 is wound around by the winding mechanism 13 to prevent the power supply cable 7 from being too long and loose, thereby preventing the loose cable from being wound into the moving parts and causing the model to jam and stop running, and also preventing it from tearing the welding points of the wires.

[0039] 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.
