Description

Technical Field

[0001] The utility model relates to the field of toys, in particular to a linkage toy driving structure and a linkage toy adopting the driving structure. Background Art

[0002] As a new type of toy, linkage toys are highly praised by people because they can perform coordinated movements of hands and feet such as dancing, which is interesting. Most of the existing linkage toys require two driving devices to drive the hands and legs or head respectively, so as to achieve coordinated movements of hands, feet and head. The structure is complicated and increases the weight of the toy, making the whole toy uncoordinated when swinging, and appearing clumsy. In order to reduce weight and simplify the structure, there are also toys driven by a single driving device, which connects the hands and hands through a single connecting rod to drive the hands and feet synchronously. The use of a single connecting rod to drive through the principle of leverage is prone to jamming, which affects play. Utility Model Content

[0003] The purpose of the utility model is to provide a linkage toy driving structure and a linkage toy using the driving structure in view of the deficiencies of the prior art, so as to solve the problems of the existing linkage toy driving structure being complex inside, occupying a large volume, being clumsy, and being easy to get stuck.

[0004] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0005] A linkage toy driving structure comprises a driving gear box, an eccentric wheel connected to the driving gear box, and a linkage bracket matched with the eccentric wheel, wherein the linkage bracket is connected with the limbs of a doll and drives the limbs of the doll to be linked; wherein the linkage bracket comprises a swing shaft arranged in the middle, and a first linkage plate and a second linkage plate arranged on both sides of the swing shaft and movably connected to the swing shaft, and the limbs of the doll are movably connected to the first linkage plate and the second linkage plate respectively; and a swing driving member matched with the eccentric wheel is arranged at the swing shaft.

[0006] Swing wings are arranged on both sides of the swing shaft, and a first connecting shaft connected with the first linkage plate or the second linkage plate is arranged on the swing wings.

[0007] A first connecting shaft sliding hole matching with the first connecting shaft is provided on the first connecting shaft plate and the second connecting shaft plate, corresponding to the first connecting shaft.

[0008] The swing driving member is a torsion spring member, and the ends of both ends of the torsion spring member extend downward to the lowermost end of the eccentric wheel and form a movable limiting portion of the convex shaft of the eccentric wheel.

[0009] The upper and lower ends of the outer sides of the first linkage plate and the second linkage plate are respectively provided with an arm connecting portion and a leg connecting portion.

[0010] The driving gear box is provided with a driving motor, a transmission gear set meshing with the power output end of the driving motor, and an eccentric wheel driving gear meshing with the transmission gear set. The eccentric wheel and the eccentric wheel driving gear rotate coaxially.

[0011] A linkage toy adopting the driving structure comprises a trunk, arms, legs and a head. The linkage toy driving structure is arranged in the trunk, and the arms and legs are movably connected to the linkage toy driving structure.

[0012] A second connecting shaft is provided at the end of the arm portion, and a third connecting shaft is provided at the end of the leg portion.

[0013] The head is arranged between the two arm parts, and two sides of the head are connected to the ends of the two arm parts.

[0014] The beneficial effects of the utility model are as follows: the driving structure of the utility model adopts a swing shaft and two linkage plates to form a linkage bracket, and then drives the linkage bracket through an eccentric wheel, so that the problem of easy jamming of connecting rod transmission can be solved while adopting a single driving gear box. In addition, the utility model adopts an elastic torsion spring to cooperate with the eccentric wheel to drive the linkage bracket, so that the action of the linkage doll adopting the driving structure of the utility model has a stronger sense of rhythm and power.
