Description

Electric toy head and neck linkage mechanism

Technical field

The utility model relates to an electric toy, in particular to a head and body neck linkage mechanism of an electric toy. Background technique

With the development of science and technology, all kinds of novelty toys are also emerging. In order to make the simulated animal toys more vivid, the head or limbs of such animal toys have been designed to be movable to enhance the realisticity of the toy and to enhance the child's interest in playing with the toy. However, the existing toys have a relatively simple manner of movement. The head or the limbs are usually reciprocated by the motor to rotate around the shaft. The head and the limbs are each only subjected to separate movements, which are relatively rigid, and rarely have the head and The movements of the limbs are organically combined to form a joint structure or a publicity. Summary of the invention

In order to overcome the above-mentioned deficiencies of the electric toy, the utility model provides an electric toy head and neck linkage mechanism.

The technical solution adopted by the utility model to solve the technical problem thereof is: an electric toy head and neck linkage mechanism, which is composed of a head movement mechanism, an upper support motion mechanism and a back movement mechanism; the head movement mechanism is capped by the head The upper link of the neck, the lower link of the neck and the middle pole of the head limb form a four-bar linkage mechanism, and the upper limb movement mechanism is composed of a middle leg of the head limb, an upper link of the upper limb, a lower link of the upper limb and a middle pole of the ankle support. a dry mechanism, the back movement mechanism The upper upper link, the middle middle link, the lower back link and the middle back of the limb form a four-bar linkage. Further: a head chin is provided at the joint of the upper jaw of the head and the upper link of the neck. Further, an upper limb rotation shaft is disposed at a joint of the upper neck link, the middle limb middle rod, the hind limb middle rod and the upper back link, and the upper limb shaft is provided with an upper limb.

Further: a drive motor is provided at the junction of the upper limb lower link, the limb back intermediate lever, and the lower back link.

Further: a chute is opened on the lower jaw of the head connected to the lower link of the neck. The electric toy head and neck linkage mechanism of the utility model has novel design, can realize the linkage of the head, the neck and the upper limb, enhances the dynamic and authenticity of the toy when traveling, and improves the playability and the ornamental of the toy.

As shown in FIG. 1 to FIG. 5, an electric toy head and neck linkage mechanism is specifically a dinosaur electric toy, which is composed of a head movement mechanism, an upper limb movement mechanism and a back movement mechanism; the head movement mechanism is composed of a head The upper jaw 1, the neck upper link 2, the neck lower link 3 and the head limb intermediate rod 4 constitute a four-bar linkage mechanism, and the upper limb movement mechanism is composed of a head limb intermediate rod 4, an upper limb upper link 5, and an upper limb lower link 6 The intermediate rod 7 is formed with a four-bar linkage mechanism, and the back movement mechanism is composed of a limb rear intermediate rod 7, a back upper link 8, a back intermediate rod 9, and a back lower link 10 to form a four-bar linkage mechanism. A head sill 11 is provided at the junction of the head 颚 1 on the head and the upper link 2 on the neck. The upper limb shaft 12 is disposed at the joint of the neck upper link 2, the head limb intermediate rod 4, the limb back intermediate rod 7 and the back upper link 8, and the upper limb shaft 13 is disposed on the upper limb shaft 12. A drive motor 14 is provided at the junction of the upper limb lower link 6, the limb back intermediate rod 7 and the lower back link 10. A chute 15 is formed in the lower jaw 11 at the junction with the lower neck link 3. Wherein, the head movement mechanism is used for controlling the opening movement of the upper jaw 1 and the lower jaw 11 of the head, the upper limb movement mechanism controls the lifting and lowering movement of the upper limb 13 , and the back movement mechanism controls the downward tilting up movement of the neck.

The action process is as follows: the driving motor 14 is started, and when the output shaft of the driving motor 14 rotates counterclockwise, the upper limb lower link 6, the limb back intermediate rod 7 and the back lower link 10 are rotated, in the process, the upper limb moving mechanism And the back movement mechanism is deflected downward by the output shaft of the driving motor 14 to realize the downward tilting movement of the neck, the upper limb 13 is lifted, and the lower neck connecting rod 3 drives the head upper jaw 1 to be opened on the lower jaw 11 of the head. The chute 15 moves up to open the mouth. On the other hand, when the output shaft of the drive motor 14 rotates clockwise, the neck is lifted up, the upper limb 13 is sunk, and the upper and lower jaws are closed. In this way, only through one drive motor 14, while achieving the dinosaur head, Linkage control of the neck and upper limbs.

Of course, the head and neck linkage mechanism of the present invention not only relates to dinosaur electric toys, but also adopts a structure similar to the joint control of the head, the neck and the upper limb driven by a motor, and also belongs to the scope claimed by the utility model. .
