In this example, the plush outer cover is shaped like a plush toy dog.
[0052] The specific working principle of this invention is as follows:
[0053] I. Body Movements:
[0054] Action ①: When the movement stands upright, the first motor 5 rotates forward, driving the first driving pulley, the first belt, and the first driven pulley to rotate. At the same time, it drives gears A30 and B31 to work. Due to the inertia generated by the rotation direction, gear B31 meshes with the front reduction gear set 3. The front reduction gear set 3 rotates and transmits power to the central gear 17. Under the tension of the compression spring 37, the movable gear 18 and the central gear 17 are interlocked and rotate synchronously. At the same time, the movable gear 18 drives gear C32 to rotate, and gear C32 drives the front axle 6 to rotate. The eccentric cams 8 at both ends of the front axle 6 rotate, causing the left front swing arm 9 and the right front swing arm 10 to swing, and the left front leg 13 and the right front leg 14 to swing. At the same time, the rear leg pull rod 33 pulls the left rear swing arm 11 and the right rear swing arm 12 to swing, and the left rear leg 15 and the right rear leg 16 to swing to complete the forward walking action.
[0055] Action ②: When the movement stands upright, the first motor 5 reverses direction. Gear B31, due to the inertia generated by the rotation direction, meshes with the rear reduction gear set 4. The rear reduction gear set 4 rotates, driving gear D34 to rotate. The eccentric disks 41 at both ends of the axle of gear D34 rotate synchronously. The eccentric disks 41 drive the seat-down lever 20 to pull the rear axle 7. One of the eccentric disks 41 rotates 180°, triggering the seat-down switch N2, stopping the first motor 5, and completing the seat-down action. At the same time, due to the rotation of the cam disk 35, the push-pull rod 19 moves back and forth. When the push-pull rod 19 moves backward, the lever 39 of the push-pull rod 19 presses against the protrusion 40 on the side of the movable gear 18. The pushing force of the push-pull rod 19 is greater than the tension of the compression spring 37, and the movable gear 18 moves outward and separates from the central gear 17.
[0056] Action ③: When the movement is in the seated position, the first motor 5 rotates forward, and the front gear set drives the eccentric wheel 44 to rotate, which is connected to the tail rod 21 through the rocker arm 45 to complete the left and right tail wagging action.
[0057] Action 4: When the dog is in the sitting position, the first motor 5 reverses and the eccentric disk 41 continues to rotate 180° until the standing limit switch N2 is triggered, the first motor 5 stops, and the standing action is completed.
[0058] Head movements:
[0059] Action ①: When the second motor 25 rotates forward, it drives the second driving pulley, the second belt, and the second driven pulley to rotate, thereby driving the upper reduction gear set 27 to work. The upper reduction gear set 27 drives the eccentric rod 28 to rotate. The U-shaped groove 50 on the eccentric rod 28 rotates along the support shaft 24 and transmits the rotation to the head seat 22. Through the optical axis, a leftward head turning and head raising movement trajectory is formed in the slide groove 48 of the ball sleeve 64 to simulate the head rubbing action of an animal. When the set angle is reached, the limit switch N5 on the left side is triggered and the second motor 25 stops.
[0060] Action ②: When the second motor 25 reverses, the head swing trajectory moves in the opposite direction until the return limit switch N4 is triggered, after which the second motor 25 stops.
[0061] Action ③: After the second motor 25 continues to reverse, the head swing trajectory continues to move to the left and upward until the right limit switch N3 is triggered, after which the second motor 25 stops.
[0062] Action 4: After the second motor 25 rotates forward, it triggers the return-to-center limit switch N4 according to the reverse trajectory line and finally returns to the starting position.
[0063] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
