Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to a sound-based positioning pulley toy. Background Technology

[0002] The various toys currently popular on the market can only be used to arrange or repeat some ordered actions, and cannot provide more fun or interactive play. Moreover, their complex structure makes them inconvenient to assemble, disassemble, and maintain, which greatly increases the cost of the toys and fails to meet customer needs.

[0003] Existing patent title: "A Novel Toy Dog," application number CN201921447723.0, discloses a novel toy dog ​​comprising a head, torso, left forelimb, right forelimb, left hindlimb, right hindlimb, and tail. The torso contains a drive mechanism for swaying the head, left forelimb, right forelimb, left hindlimb, right hindlimb, and tail. The drive mechanism includes a drive mechanism support frame, a drive gearbox, and head drive components, tail drive components, synchronized drive components for the left and right forelimbs, left and right hindlimbs, left and left hindlimbs, and right forelimbs connected to the drive gearbox. These drive components enable the toy dog ​​to walk, crouch, wag its tail, and bark and nod. However, this toy cannot be manually controlled to produce specific actions, nor can it identify the direction of the drive motor based on sound to perform specific actions. It also cannot achieve large-amplitude swaying movements. Furthermore, the toy has a complex structure, high manufacturing cost, insufficient dynamism, and limited entertainment value.

[0004] Therefore, the structure of this toy still needs further improvement. Utility Model Content
