DETAILED DESCRIPTION

[0030] All features disclosed in this specification, or all steps of any methods or processes disclosed in this specification, can be combined in any combination, except combinations where at least some of the features and / or steps are mutually exclusive.

[0031] As shown in Figures 1-2 and Figure 3 , the utility model provides a blink movement structure suitable for plush pet toy, through improved transmission mode and component design, greatly promoted structure simplification, stability and blink effect real sense. The movement structure includes a gear box 7, gear transmission module 14 is installed in gear box 7, gear transmission module 14 is driven by motor, realizes the power transmission of blink action. Gear box 7 is arranged at the core position of movement, ensures its stability and transmission efficiency. Gear transmission module 14 is reasonably designed, through the rotation transmission power of motor to transmission rod 4, make the action of whole structure more stable, low noise, be suitable for application in the plush pet toy of higher interactivity.

[0032] The both sides of gear box 7 are provided with movement cover 3, for protecting gear transmission module 14 and other transmission components from outside interference, increase the aesthetic property of whole structure simultaneously. The inside of movement cover 3 is equipped with guide limiting structure, through the limiting of transmission rod 4's movement path, realize transmission rod 4's accurate guidance in single direction in reciprocating motion process, ensure that transmission rod 4 does not occur horizontal deviation or distortion in the operation process. Guide limiting structure is designed through limiting guide convex part 13 and the limiting contact surface 8 of transmission rod 4 upper and lower end, make transmission rod 4 only do reciprocating motion along one direction, as shown in Figure 3 .

[0033] Transmission rod 4 is installed in each movement cover 3, wherein the design of transmission rod 4 is T-shaped transmission rod 4, simple structure and practical. One end of transmission rod 4 is connected with eccentric wheel 6, drives transmission rod 4 to make reciprocating motion along guide limiting structure through the rotation of eccentric wheel 6. Eccentric wheel 6 is fixed on the output shaft of gear box 7, can efficiently convert the rotary motion of motor into the linear reciprocating motion of T-shaped transmission rod 4.

[0034] The transmission rod 4 is provided with two first slotted holes 12 at one end, which are used to connect the hinged ears of the eyelid assembly 2, so that the transmission rod 4 can drive the opening and closing of the eyelid during reciprocating movement, thereby simulating the effect of blinking.

[0035] The transmission rod 4 connects the first hinged ear 18 of the eyelid assembly 2 and the connecting shaft 11 through the two first slotted holes 12, and the connecting shaft 11 passes through the first hinged ear 18 and the first slotted hole 12 respectively, ensuring the stable connection of the eyelid assembly 2 and the transmission rod 4.

[0036] When the transmission rod 4 reciprocates, it drives the up and down movement of the eyelid assembly 2 through the connection with the first slotted hole 12, completes the synchronous opening and closing of the eyelid, effectively simplifies the transmission mechanism, avoids the problem of asynchronous movement of the upper and lower eyelids in the traditional structure due to the use of double transmission rods 4, and ensures the authenticity and consistency of the blinking action.

[0037] The eyelid assembly 2 is installed outside the eyeball 15 and includes a first eyelid 21 and a second eyelid 22 for up and down movement respectively. The first eyelid 21 and the second eyelid 22 are provided with second hinged ears 17 at a position away from the first hinged ear 18, and the two eyelids are hinged to each other to ensure that they can always maintain a certain contact state during opening and closing. The eyeball 15 is provided with a fixed ear 16 at a position corresponding to the second hinged ear 17 to enhance the connection stability. The fixed ear 16 and the second hinged ear 17 both extend into the mounting slot of the eye support frame 9 and are connected by a movement center shaft 10, so that the eyelid assembly 2 can be opened and closed up and down along the movement center shaft 10 under the drive of the transmission rod 4.

[0038] In order to further simplify the structure and assembly difficulty of the transmission rod 4, the other end of the transmission rod 4 is provided with a second slotted hole 5, and the drive shaft of the eccentric wheel 6 extends into the second slotted hole 5. The transmission rod 4 produces longitudinal linear reciprocating motion through the rotation of the eccentric wheel 6. The longitudinal arrangement of the second slotted hole 5 helps the stable movement of the transmission rod 4, so that it always maintains linear motion under the drive of the eccentric wheel 6, avoiding the wear of parts caused by irregular movement.

[0039] As Figure 1As shown, both sides of the first eyelid and the second eyelid are provided with a card slot 24, and an arc-shaped card buckle film 23 is installed in the card slot on each eyelid, and card hooks 231 are provided on both sides of the arc-shaped card buckle film for hooking the card slot, and the arc-shaped card buckle film 23 is sewn to the inner eyelid position of the plush leather shell to realize the connection between the plush leather shell and the eyelid assembly. The arc-shaped card buckle film 23 is sewn to the inner eyelid position of the plush leather shell, and then the two raised ends of the arc-shaped card buckle film 23 are snapped into the card slot 24 on the eyelid assembly. There are 4 card points in total for the upper and lower eyelids of each eye, so that the leather shell and the movement are tightly combined. When the eyelids of the movement move, the leather shell moves with it. While the combination is tight, the difficulty of assembly is reduced, and the movement plastic parts are not exposed, and the plush image is more simulated.

[0040] In addition, the movement structure also includes an eye mask 1, which is installed on the outside of the eyeball 15 and the eyelid fastener, can effectively protect the internal movement components, and is fixedly assembled with the movement cover 3 and the gear box 7 to ensure the stability of the overall structure.

[0041] In this embodiment, the eye mask 1 is narrow at the top and wide at the bottom, fitting the curved shape of the plush pet toy's head, making the overall design more consistent with the plush toy's appearance. In terms of structural design, the angle between the two eyes is designed to be slightly tilted, which better simulates the effect of a natural blink, increasing the toy's interactivity and visual appeal.
