Description

Technical Field

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

[0002] Building blocks, as a classic type of construction toy, have long held an important place in children's education and entertainment. Through standardized modular design, they allow users to construct diverse three-dimensional structures, such as buildings, vehicles, and animal models, by assembling building blocks of different shapes and sizes. Traditional building blocks are typically made of plastic, with interlocking structures such as protrusions and grooves on the surface, achieving stable connections through physical interlocking, while also possessing the characteristic of being repeatedly disassembled and reassembled. The core value of these toys lies in cultivating users' spatial awareness, hands-on skills, and creative thinking. Their open-ended assembly logic allows users to freely unleash their imagination, realizing everything from simple structures to complex scenes.

[0003] However, existing building block toy technology has significant limitations—the vast majority of products only support static display functions. Once assembled, the models typically exist as fixed decorations, lacking dynamic interactive capabilities. For example, in animal-shaped building block toys, the limbs and head cannot move automatically after assembly; this static characteristic directly restricts the expansion of the interactive features of building block toys. For child users, a purely static display is unlikely to maintain long-term interest. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a movable structure for a building block toy in which the head and limbs can swing automatically at the same time.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a movable structure for a building block toy, comprising a main body, a head, two front swinging parts and two rear swinging parts, wherein the head is hinged to the front of the main body, the two rear swinging parts are hinged to the two sides of the rear of the main body, and a driving device is provided on the main body. The driving device includes a drive motor, a gear set, and two transmission wheels. The two transmission wheels are located on both sides of the driving device. The gear set includes a transmission gear, a transmission shaft is provided on the transmission gear, a transmission key is provided on the transmission shaft, a keyway matching the transmission key is provided on the transmission wheel, the transmission wheel is inserted into the transmission shaft, and a mounting groove is provided on the transmission wheel at a position offset from the keyway.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example: Reference Figure 1 A movable structure for a building block toy includes a main body 1, a head 2, two front swing parts 3 and two rear swing parts 4. The head 2 is hinged to the front of the main body 1, and the two rear swing parts 4 are hinged to the rear sides of the main body 1. A driving device is provided on the main body 1 to drive the head 2, the front swing parts 3 and the rear swing parts 4 to move. The main body 1 is also provided with a battery compartment (not shown in the figure) for installing batteries to provide power to the driving device. refer to Figure 4 The driving device includes a drive motor 71, a gear set 72, and two transmission wheels 73. The two transmission wheels 73 are located on both sides of the driving device. The gear set 72 includes a transmission gear 721. A transmission shaft 722 is provided on the transmission gear 721. A transmission key is provided on the transmission shaft 722. A keyway 74 matching the transmission key is provided on the transmission wheel 73. The transmission wheel 73 is inserted into the transmission shaft 722. The drive motor 71 drives the gear set 72 to run, thereby driving the transmission shaft on the transmission gear to rotate. The transmission shaft drives the transmission wheel 73 to rotate around the transmission shaft 722 through the transmission key. An installation groove is provided on the transmission wheel 73 at a position offset from the keyway 74. A front rotating rod 31 is provided on the front swing part 3 and can be rotatably inserted into the installation groove. When the transmission wheel rotates, the front rotating rod 31 rotates around the transmission shaft 722, thereby driving the front swing part 3 to swing, simulating the movement of an animal's forelimb. A first connecting rod 61 is rotatably connected to the front rotating rod 31. The rear swing part 4 is provided with a rear rotating rod 41, which is rotatably connected to the rear of the first connecting rod 61. The rotatable connection means that the rear rotating rod can rotate on its own after installation. A second connecting rod 62 is also rotatably connected to the front rotating rod 31 on one side. The head part 2 is provided with a head rotating rod 22 near the second connecting rod 62, which is rotatably connected to the front of the second connecting rod 62. When the front rotating rod 31 rotates around the transmission shaft 722, the first connecting rod 61 and the second connecting rod 62 drive the rear swing part 4 and the head part 2 to swing, simulating the movement of the head and hind limbs of an animal. This breaks through the single form of traditional static building blocks and significantly improves the dynamic interactive experience and fun when playing with them.

[0020] Further reference Figure 4 The first link 61 and the second link 62 each include two link assemblies 63 and at least two connecting pins 64. Each link assembly 63 has a plurality of equally spaced connecting holes 631 arranged in a straight line. At least two connecting holes 631 overlap on the two link assemblies 63, and connecting pins 64 are inserted into the at least two overlapping connecting holes 631. The connecting holes 631 are also used to connect with the front rotating rod 31, the rear rotating rod 41, and the head rotating rod 22. The modular design enables length adjustment, allowing the first link 61 and the second link 62 to flexibly adapt to the head 2 and the rear swinging part 4. To meet different swing requirements and avoid creating separate molds for different length specifications, thereby reducing production costs and inventory management complexity, the connecting pin 64 is provided with elastic buckles 8 at both ends. In this embodiment, the elastic buckle 8 includes two arc-shaped elastic pieces 81. The outer ends of the elastic pieces 81 extend outward to form a snap-fit ​​portion 82. During installation, the elastic pieces 81 are compressed inward to be inserted into the connecting hole 631. After the snap-fit ​​portion passes through the connecting hole 631, the elastic pieces 81 open outward and are snapped onto the outside of the connecting hole 631 by the snap-fit ​​portion to prevent them from being pulled out. In addition, the arc-shaped elastic pieces do not affect the rotation of the elastic buckle 8.

[0021] Further reference Figure 2 , 3 The main body 1 is provided with a limiting rod 11, and the front swing part above the front rotating rod 31 is provided with a long strip-shaped limiting groove 32. The limiting rod 11 is placed in the limiting groove 32 to limit the swing trajectory of the front swing part 3, so that its trajectory is more in line with the walking posture.

[0022] Further reference Figure 2 , 3The rear swing part 4 is rotatably connected to a first pivot part 42, and the main body 1 is rotatably connected to a second pivot part 14. The second pivot part 14 is provided with a cross groove 141 on the side facing the first pivot part 42. The shape of the end of the first pivot part 42 facing the second pivot part 14 matches the cross groove 141. The first pivot part 42 is inserted into the second pivot part 14, thereby realizing the hinge connection between the rear swing part 4 and the main body 1. The first pivot part 42 and the second pivot part 14 are provided with elastic buckles 8 on the side away from each other. The first pivot part 42 and the second pivot part 14 are connected to the rear swing part 4 and the main body 1 respectively through the elastic buckles 8.

[0023] Further reference Figure 2 , 3 A mounting bracket 12 is provided at the front of the main body 1. A mounting bracket pivot 13 is provided on the mounting bracket 12. A rotating component 21 is rotatably connected to the mounting bracket pivot 13. The head part 2 is inserted into the rotating component 21, thereby realizing the hinge connection between the head part 2 and the main body 1.

[0024] Further reference Figure 1 , 2 The main body 1 is also connected to the front of the jaw 5, which is located below the head 2. The head 2 and the jaw 5 are designed separately. The head 2 can swing relative to the jaw 5 to simulate the chewing action of the lower jaw when the animal is eating, giving the toy a biological realism and enhancing the visual expression and scene immersion.

[0025] Furthermore, the front swinging part 3, the rear swinging part 4, the head part 2, and the jaw part 5 are assembled from building blocks, which can be used to create different shapes.
